     (c) The Trust is intended to be a grantor trust, of which Company is the
grantor, within the meaning of subpart E, part I, subchapter J, chapter 1,
subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

     (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of the Company and shall be used exclusively
for the uses and purposes of Plan Participants and general creditors as herein
set forth. Plan Participants and their beneficiaries shall have no preferred
claim on, or any beneficial ownership interest in, any assets of the Trust. Any
rights created under the Plan and this Trust Agreement shall be mere unsecured
contractual rights of Plan Participants and their beneficiaries against Company.
Any assets held by the Trust will be subject to the claims of Company's general
creditors under federal and state law in the event of Insolvency, as defined in
Section 3(a) herein.

     (e) In addition to depositing the Ten Dollars ($10.00) necessary to
establish the initial principal of the Trust pursuant to Section 1(a), the
Company shall also deposit, no later than 45 days following the effective date
of the Trust Agreement, an amount which equates to the funds deferred (plus
accrued earnings as provided in the Plan) by the Plan Participants pursuant to
the Plan through March 31, 2000. Thereafter, no later than 45 days following the
end of each calendar quarter, the Company shall deposit funds deferred (plus
accrued earnings as provided in the Plan) by Plan Participants in such calendar
quarter; provided, however, the Company may instead make periodic deposits of
funds concurrently with the deferrals made by Plan Participants to the extent
Plan Participants have selected investment options that are authorized Trust
investments. No later than 45 days following the end of each calendar year (or
from time to time at the discretion of the Company in order to assure adequate
funding of the Trust and proper crediting of Plan Participant deferrals and
related earnings), the Company shall deposit additional funds into the Trust in
an amount sufficient to pay each Plan Participant the anticipated benefits as
provided in the Plan.

     Section 2. Payment to Plan Participants and Their Beneficiaries.

     (a) Company shall deliver to Trustee a schedule (the "Payment Schedule")
that indicates, with respect to any payment required under the terms of the Plan
or Section 2(c) below, the amounts payable in respect of each Plan Participant
(and his or her beneficiaries), that provides a formula or other instructions
acceptable to Trustee for determining the amounts so payable, the form in which
such amounts are to be paid (as provided for or available under the Plan), and
the time of commencement for payment of such amounts. Except as otherwise
provided herein, Trustee shall make payments to the Plan Participants and their
beneficiaries in accordance with such Payment Schedule. The Company shall make
provision for the reporting and withholding of any federal, state or local taxes
that may be required to be withheld with respect to the payment of benefits
pursuant to the terms of the Plan and shall pay amounts withheld to the
appropriate taxing authorities.

     (b) The entitlement of a Plan Participant or his or her beneficiaries to
benefits under the Plan shall be determined by Company or such party as it shall
designate under the Plan, and

                                                                             -2-
<PAGE>   3

any claim for such benefits shall be considered and reviewed under the
procedures set out in the Plan.

     (c) Notwithstanding the foregoing provisions of this Section 2 (and
pursuant to Section 5.7 of the Plan), each Participant shall receive payment of
such Participant's Account Balance under the Plan within six (6) months
following the occurrence of any event or condition which, after the expiration
of any applicable cure or grace period, gives the holder of any note, debenture
or other evidence of indebtedness (whether now or hereafter existing) of the
Company or any of its subsidiaries, or any person acting on such holder's
behalf, the right to require the repurchase, redemption or repayment of all or a
portion of such indebtedness by the Company or any of its subsidiaries.

     (d) Company may make payment of benefits directly to Plan Participants or
their beneficiaries as they become due under the terms of the Plan or Section
2(c) above. Company shall notify Trustee of its decision to make payment of
benefits directly prior to the time amounts are payable to Participants or their
beneficiaries. In addition, if the principal of the Trust, and any earnings
thereon, are not sufficient to make payments of benefits in accordance with the
terms of the Plan and Section 2(c) above, Company shall make the balance of each
such payment as it falls due. Trustee shall notify Company where principal and
earnings are not sufficient.

     Section 3. Trustee Responsibility Regarding Payments to Trust Beneficiary
                When Company Is Insolvent.

     (a) Trustee shall cease payment of benefits to Plan Participants and their
beneficiaries if the Company is Insolvent. Company shall be considered
"Insolvent" for purposes of this Trust Agreement if, (i) Company is unable to
pay its debts as they become due, (ii) Company is subject to a pending
proceeding as a debtor under the United States Bankruptcy Code, or (iii) Company
is determined to be insolvent by the Federal Deposit Insurance Corporation.

     (b) At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of Company under federal and state law as set forth
below:

          (1) The Board of Directors and the Chief Executive Officer of Company
shall have the duty to inform Trustee in writing of Company's Insolvency. If a
person claiming to be a creditor of Company alleges in writing to Trustee that
Company has become Insolvent, Trustee shall determine whether Company is
Insolvent and, pending such determination, Trustee shall discontinue payment of
benefits to Plan Participants or their beneficiaries. In such a situation, The
Trustee may ask the Board of Directors for a resolution and/or the Chief
Executive Officer for an affidavit that the Company is not Insolvent. The
Trustee may rely on such resolution or affidavit without further investigation
if the document(s) unequivocally state that the Company is not Insolvent. If the
Board of Directors or Chief Executive Officer fails to provide the requested
documentation, the Trustee may treat the Company as Insolvent until clear and
convincing evidence to the contrary is available. Notices of Insolvency shall be
mailed to: Department Manager, Retirement Services, Trust and Investment
Services Group, SunTrust Bank, 200 S. Orange Avenue, Suite 800, Orlando, FL
32802.

                                                                             -3-
<PAGE>   4

          (2) Unless Trustee has actual knowledge of Company's Insolvency, or
has received notice from Company or a person claiming to be a creditor alleging
that Company is Insolvent, Trustee shall have no duty to inquire whether Company
is Insolvent. Trustee may in all events rely on such evidence concerning
Company's solvency as may be furnished to Trustee and that provides Trustee with
a reasonable basis for making a determination concerning Company's solvency.

          (3) If at any time Trustee has determined that Company is Insolvent,
Trustee shall discontinue payments to Plan Participants or their beneficiaries
and shall hold the assets of the Trust for the benefits of Company's general
creditors. Nothing in this Trust Agreement shall in any way diminish any rights
of Plan Participants or their beneficiaries to pursue their rights as general
creditors of Company with respect to benefits due under the Plan or otherwise.

          (4) Trustee shall resume the payment of benefits to Plan Participants
or their beneficiaries in accordance with Section 2 of this Trust Agreement only
after the Trustee receives written notification from the Board of Directors or
Chief Executive Officer of the Company that Company is not Insolvent.

     (c) Provided that there are sufficient assets, if Trustee discontinues the
payment of benefits from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
Participants or their beneficiaries under the terms of the Plan for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
Participants or their beneficiaries by Company in lieu of the payments provided
for hereunder during any such period of discontinuance.

     Section 4. Payments to Company

     Except as provided in Section 3 hereof, after the Trust has become
irrevocable, Company shall have no right or power to direct Trustee to return to
Company or to divert to others any of the Trust assets before all payments of
benefits have been made to Plan Participants and their beneficiaries pursuant to
the terms of the Plans.

     Section 5. Investment Authority.

     (a) Trustee shall invest in life insurance policies, annuities, any and all
securities or obligations (including stock or rights to acquire stock) including
securities or obligations issued by Company, as determined by the Trustee,
unless otherwise instructed by the Chief Financial Officer of the Company. All
rights associated with assets of the Trust shall be exercised by Trustee or the
person designated by Trustee, and shall in no event be exercisable by or rest
with Plan Participants.

     (b) Company may direct the Trustee as to the investment of any or all
assets held in the Trust Fund. The Trustee shall not be liable for, and the
Company shall indemnify and hold the Trustee harmless against, any liability,
loss, expense, assessment or cost incurred by the

                                                                             -4-

the instructions of the Company given under this section.

     Section 6. Disposition of Income.

     During the term of this Trust, all income received by the Trust, net of
expenses and taxes, shall be accumulated and reinvested.

     Section 7. Accounting by Trustee.

     Trustee shall keep accurate and detailed records of all investments,
receipts, disbursements, and all other transactions required to be made,
including such specific records as shall be agreed upon in writing between
Company and Trustee. Within sixty (60) days following the close of each calendar
year and within forty-five (45) days after the removal or resignation of
Trustee, Trustee shall deliver to Company a written account of the
administration of the Trust during such year or during the period from the close
of the last preceding year to the date of such removal or resignation, setting
forth all investments, receipts, disbursements and other transactions effected
by it, including a description of all securities and investments purchased and
sold with the cost or net proceeds of such purchases or sales (accrued interest
paid or receivable being shown separately), and showing all cash, securities and
other property held in the Trust at the end of such year or as of the date of
such removal or resignation, as the case may be.

     Section 8. Responsibility of Trustee.

     (a) Trustee shall act with the care, skill, prudence and diligence under
the circumstances then prevailing that a prudent person acting in like capacity
and familiar with such matters would use in the conduct of an enterprise of a
like character and with like aims, provided, however, that Trustee shall incur
no liability to any person for any action taken pursuant to a direction, request
or approval given by Company or an officer of Company which is contemplated by,
and in conformity with, the terms of the Plan or this Trust and is given in
writing by Company. In the event of a dispute between Company and a party,
Trustee may apply to a court of competent jurisdiction to resolve the dispute.

     (b) If Trustee undertakes or defends any litigation arising in connection
with this Trust, Company agrees to indemnify Trustee against Trustee's costs,
expenses and liabilities (including, without limitation, attorneys' fees and
expenses) relating thereto and to be primarily liable for such payments,
provided the Trustee shall not be indemnified for any action taken by the
Trustee which is in breach of its duties and obligations under this Trust
Agreement. If Company does not pay such costs, expenses and liabilities in a
reasonably timely manner, Trustee may obtain payment from the Trust.

     (c) Trustee may consult with legal counsel (who may also be counsel for
Company generally) with respect to any of its duties or obligations hereunder.

                                                                             -5-

assign the policy (as distinct from conversion of the policy to a different
form) other than to a successor Trustee, or to loan to any person the proceeds
of any borrowing against such policy.

     (f) However, notwithstanding the provisions of Section 8(e) above, Trustee
may loan to Company the proceeds of any borrowing against an insurance policy or
annuity held as an asset of the Trust.

shall then occur.

                  This Pooling and Servicing Agreement (this "Agreement"), is
dated and effective as of December 1, 2000, among GMAC COMMERCIAL MORTGAGE
SECURITIES, INC., as Depositor, GMAC COMMERCIAL MORTGAGE CORPORATION, as Master
Servicer, GMAC COMMERCIAL MORTGAGE CORPORATION, as Special Servicer, and LASALLE
BANK NATIONAL ASSOCIATION, as Trustee and ABN AMRO BANK N.V., as Fiscal Agent.

PRELIMINARY STATEMENT:

                  The Depositor intends to sell the Certificates, to be issued
hereunder in multiple Classes, which in the aggregate will evidence the entire
beneficial ownership interest in the Trust Fund to be created hereunder, the
primary assets of which will be the Mortgage Loans and the Companion Loans. The
aggregate of the initial Cut-off Date Principal Balances of the Mortgage Loans
is approximately $1,269,742,026, and the Cut-off Date Principal Balances of the
Companion Loans is approximately $48,379,248.

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Mortgage Loans and the Companion
Loans (exclusive of that portion of interest payments thereon that constitute
Excess Interest) and certain other related assets subject to this Agreement as a
REMIC for federal income tax purposes, and such segregated pool of assets will
be designated as "REMIC I". The Class R-I Certificates will represent the sole
class of "residual interests" in REMIC I for purposes of the REMIC Provisions
under federal income tax law. With respect to each Mortgage Loan or Companion
Loan, there shall be a corresponding REMIC I Regular Interest. The designation
for each such REMIC I Regular Interest shall be the loan number for the related
Mortgage Loan or Companion Loan set forth on the schedule of Mortgage Loans and
Loan Groups attached hereto as Schedule I. The REMIC I Remittance Rate (as
defined herein) and the initial Uncertificated Principal Balance of each such
REMIC I Regular Interest shall be based on the Net Mortgage Rate as of the
Cut-off Date and the Cut-off Date Principal Balance, respectively, for the
related Mortgage Loan or Companion Loan. Determined solely for purposes of
satisfying Treasury Regulation Section 1.860G-1(a)(4)(iii), the "latest possible
maturity date" for each such REMIC I Regular Interest shall be the first
Distribution Date that follows the Stated Maturity Date for the related Mortgage
Loan or Companion Loan. None of the REMIC I Regular Interests will be
certificated.

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the REMIC I Regular Interests as a REMIC
for federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC II." The Class R-II Certificates will represent the sole
class of "residual interests" in REMIC II for purposes of the REMIC Provisions
under federal income tax law. The following table irrevocably sets forth the
designation, REMIC II Remittance Rate and the initial Uncertificated Principal
Balance for each of the REMIC II Regular Interests. Determined solely for
purposes of satisfying Treasury Regulation Section 1.860G-1(a)(4)(iii), the
"latest possible maturity date" for each REMIC II Regular Interest shall be the
first Distribution Date that is at least two years after the end of the
remaining amortization schedule of the Mortgage Loan or Companion Loan that has,
as of the Closing Date, the longest remaining amortization schedule,
irrespective of its scheduled maturity. None of the REMIC II Regular Interests
will be certificated.

*   Calculated in accordance with the definition of "REMIC II Remittance Rate."

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the REMIC II Regular Interests as a
REMIC for federal income tax purposes, and such segregated pool of assets will
be designated as "REMIC III". The Class R-III Certificates will represent the
sole class of "residual interests" in REMIC III for purposes of the REMIC
Provisions under federal income tax law. The following table irrevocably sets
forth the designation, the Pass-Through Rate and initial Class Principal Balance

                        ORIGINAL ISSUANCE OF CERTIFICATES

                                Loans and Companion Loans.

                  (a) The Depositor, concurrently with the execution and
delivery hereof, does hereby establish a trust, appoint the Trustee to serve as
trustee of such trust and assign to the Trustee without recourse for the benefit
of the Certificateholders all the right, title and interest of the Depositor,
including any security interest therein for the benefit of the Depositor, in, to

Loan Schedule, (ii) Sections 2, 4(a), 6 and 13 of each Mortgage Loan Purchase

interest and principal received or receivable on or with respect to the Mortgage
Loans and Companion Loans (other than payments of principal and interest due and
payable on the Mortgage Loans and Companion Loans on or before the Cut-off
Date). The transfer of the Mortgage Loans and Companion Loans and the related
rights and property accomplished hereby is absolute and, notwithstanding Section
11.07, is intended by the parties to constitute a sale.

                  (b) In connection with the Depositor's assignment pursuant to
subsection (a) above, the Depositor shall direct, and hereby represents and
warrants that it has directed, each Mortgage Loan Seller pursuant to the related
Mortgage Loan Purchase Agreement to deliver to and deposit with, or cause to be
delivered to and deposited with, the Trustee or the Custodian (with a copy to
the Master Servicer), on or before the Closing Date, the Mortgage File for each
of such Mortgage Loan Seller's Mortgage Loans and Companion Loans, as
applicable, so assigned. If the related Mortgage Loan Seller cannot deliver, or
cause to be delivered as to any Mortgage Loan or Companion Loan, the original
Mortgage Note, the Mortgage Loan Seller shall deliver a copy or duplicate
original of such Mortgage Note, together with an affidavit certifying that the
original thereof has been lost or destroyed. If the related Mortgage Loan Seller
cannot deliver, or cause to be delivered, as to any Mortgage Loan or Companion
Loan, any of the documents and/or instruments referred to in clauses (2), (4),
(11) and (12) of the definition of "Mortgage File", with evidence of recording
or filing, as the case may be, thereon, because of a delay caused by the public
recording or filing office where such document or instrument has been delivered
for recordation or filing, or because such original recorded document has been
lost or returned from the recording or filing office and subsequently lost, as
the case may be, the

                                       63
<PAGE>

delivery requirements of the related Mortgage Loan Purchase Agreement and this
Section 2.01(b) shall be deemed to have been satisfied as to such missing
document or instrument, and such missing document or instrument shall be deemed
to have been included in the Mortgage File, provided that a photocopy of such
missing document or instrument (certified by the related Mortgage Loan Seller to
be a true and complete copy of the original thereof submitted for recording or
filing, as the case may be) is delivered to the Trustee or a Custodian appointed
thereby on or before the Closing Date and either the original of such missing
document or instrument, or a copy thereof, with evidence of recording or filing,
as the case may be, thereon, is delivered to or at the direction of the Trustee
within 180 days of the Closing Date (or within such longer period after the
Closing Date as the Trustee may consent to, which consent shall not be
unreasonably withheld so long as the related Mortgage Loan Seller has provided
the Trustee with evidence of such recording or filing, as the case may be, or
has certified to the Trustee as to the occurrence of such recording or filing,
as the case may be, and is, as certified to the Trustee no less often than
quarterly, in good faith attempting to obtain from the appropriate county
recorder's or filing office such original or copy). Upon request, the Trustee
shall provide a copy of any such certification, promptly after receipt thereof,
to any Certificate Owner holding a Certificate in the Controlling Class that has
provided a certification to the Trustee in the form attached hereto as Exhibit
K. If the related Mortgage Loan Seller cannot deliver, or cause to be delivered,
as to any Mortgage Loan or Companion Loan, the original or a copy of the related
lender's title insurance policy referred to in clause (9) of the definition of
"Mortgage File" solely because such policy has not yet been issued, the delivery
requirements of this Section 2.01(b) shall be deemed to be satisfied as to such
missing item, and such missing item shall be deemed to have been included in the
related Mortgage File, provided that the related Mortgage Loan Seller shall have
delivered to the Trustee or a Custodian appointed thereby, on or before the
Closing Date, a commitment for title insurance "marked-up" at the closing of
such Mortgage Loan or Companion Loan, and the related Mortgage Loan Seller shall
deliver to the Trustee or such Custodian, promptly following the receipt
thereof, the original related lender's title insurance policy (or a copy
thereof). In addition, notwithstanding anything to the contrary contained
herein, if there exists with respect to any group of related
Cross-Collateralized Mortgage Loans only one original of any document referred
to in the definition of "Mortgage File" covering all the Mortgage Loans and
Companion Loans in such group, then the inclusion of the original of such
document in the Mortgage File for any of the Mortgage Loans and Companion Loans
in such group shall be deemed an inclusion of such original in the Mortgage File
for each such Mortgage Loan or Companion Loan. Neither the Trustee nor any
Custodian shall in any way be liable for any failure by the Mortgage Loan Seller
or the Depositor to comply with the delivery requirements of the Mortgage Loan
Purchase Agreement and this Section 2.01(b).

                  If any of the endorsements referred to in clause (1) of the
definition of "Mortgage File", or any of the assignments referred to in clauses
(3), (5) and (7) of the definition of "Mortgage File", are delivered to the
Trustee in blank, the Trustee shall be responsible for promptly (and in any
event within 45 days of the Closing Date) completing the related endorsement or
assignment in the name of the Trustee (in such capacity) and in any event prior
to releasing possession thereof.

                  (c) Except under the circumstances provided for in the last
sentence of this subsection (c), the Trustee shall, as to each Mortgage Loan and
Companion Loan, at the expense of the related Mortgage Loan Seller, promptly
(and in any event within 45 days of the Closing

                                       64
<PAGE>

Date) cause to be submitted for recording or filing, as the case may be, in the
appropriate public office for real property records or UCC Financing Statements,
as appropriate, each assignment referred to in clauses (3) and (5) of the
definition of "Mortgage File" and each UCC-2 and UCC-3 referred to in clause
(11)(B) of the definition of "Mortgage File"; provided, however, that each
Mortgage Loan Seller shall have the right to direct the Trustee, in writing, to
cause the aforementioned recording and filing requirements to be completed
(within the specified time period) by a Person other than the Trustee, in which
case the Trustee shall (i) promptly deliver the referenced documents to such
Person for recording and filing and (ii) notify the related Mortgage Loan Seller
with respect to each Mortgage Loan and Companion Loan for which the related
assignment or file copy of any UCC-2 and UCC-3 has not been received within the
time period specified in Section 2.02(b). Each such assignment shall reflect
that it should be returned by the public recording office to the Trustee or its
designee following recording, and each such UCC-2 and UCC-3 shall reflect that
the file copy thereof should be returned to the Trustee or its designee
following filing. Promptly following receipt, the Trustee shall, at the expense
of the respective Mortgage Loan Seller, deliver a copy of any such document or
instrument to the Master Servicer. If any such document or instrument is lost or
returned unrecorded or unfiled, as the case may be, because of a defect therein,
the Trustee shall direct the related Mortgage Loan Seller pursuant to the
related Mortgage Loan Purchase Agreement promptly to prepare or cause to be
prepared a substitute therefor or cure such defect, as the case may be, and
thereafter the Trustee shall upon receipt thereof cause the same to be duly
recorded or filed, as appropriate.

                  (d) All documents and records in the Depositor's or any
Mortgage Loan Seller's possession relating to the Mortgage Loans and Companion
Loans that are not required to be a part of a Mortgage File in accordance with
the definition thereof shall be delivered to the Master Servicer on or before
the Closing Date and shall be held by the Master Servicer (or a Sub-Servicer
retained thereby) on behalf of the Trustee in trust for the benefit of the
Certificateholders. If the Sub-Servicer shall hold any original documents and
records delivered to it pursuant to this clause (d) then the Sub-Servicer shall
deliver copies thereof to the Master Servicer.

                  (e) In connection with the Depositor's assignment pursuant to
subsection (a) above, the Depositor shall deliver, and hereby represents and
warrants that it has delivered, to the Trustee and the Master Servicer, on or
before the Closing Date, a fully executed original counterpart of each Mortgage
Loan Purchase Agreement and each Supplemental Agreement, as in full force and
effect, without amendment or modification, on the Closing Date.

                  SECTION 2.02  Acceptance by Trustee.

                  (a) The Trustee, by the execution and delivery of this
Agreement, hereby certifies receipt by it or a Custodian on its behalf, subject
to the provisions of Section 2.01 and the further review provided for in this
Section 2.02, and further subject to any exceptions noted on any exception
report prepared by the Trustee or such Custodian and attached hereto as Schedule
II, of the documents specified in clauses (1), (2), (3), (9) and (12) of the
definition of "Mortgage File", of a fully executed original counterpart of each
Mortgage Loan Purchase Agreement and of all other assets included in REMIC I and
delivered to it, in good faith and without notice of any adverse claim, and
declares that it or a Custodian on its behalf holds and will hold such documents
and the other documents delivered or caused to be delivered by the

                                       65

Mortgage Loan Sellers constituting the Mortgage Files, and that it holds and
will hold such other assets included in REMIC I, in trust for the exclusive use
and benefit of all present and future Certificateholders. In connection with the
foregoing, the Trustee hereby certifies, subject to any exceptions noted on any
exception report prepared by the Trustee or the Custodian and attached hereto as
Schedule II, as to each Mortgage Note, that it (A) appears regular on its face
(handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Mortgagor), (B) appears to have been executed
(where appropriate) and (C) purports to relate to such Mortgage Loan or
Companion Loan.

                  (b) Within 60 days of the Closing Date, the Trustee or a
Custodian on its behalf shall review each of the Mortgage Loan or Companion Loan
documents delivered or caused to be delivered by the Mortgage Loan Sellers
constituting the Mortgage Files; and, promptly following such review, the
Trustee shall certify in writing in the form attached hereto as Schedule III to
each of the Depositor, the Master Servicer, the Special Servicer, each
Certificateholder in the Controlling Class, each Mortgage Loan Seller and, upon
request, any Certificateholder that, as to each Mortgage Loan or Companion Loan
listed in the Mortgage Loan Schedule (other than any Mortgage Loan or Companion
Loan paid in full or any Mortgage Loan or Companion Loan specifically identified
in any exception report annexed thereto as not being covered by such
certification), (i) all documents specified in clauses (1) through (5), (9),
(11) and (12) (in the case of clause (11), without regard to whether such UCC
financing statements were in the possession of the Mortgage Loan Seller (or its
agent)) of the definition of "Mortgage File" are in its possession or the
related Mortgage Loan Seller has otherwise satisfied the delivery requirements
in accordance with Section 2.01(b) and (ii) all documents delivered or caused to
be delivered by the related Mortgage Loan Seller constituting the related
Mortgage File have been reviewed by it or by a Custodian on its behalf and (A)
appear regular on their face and relate to such Mortgage Loan or Companion Loan,
(B) appear to have been executed (where appropriate) and (C) purport to relate
to such Mortgage Loan or Companion Loan. If the Trustee's certification pursuant
to the preceding sentence includes an exception report, or if such certification
indicates that any recording or filing required by Section 2.01(c) has not been
completed with respect to a Mortgage Loan or Companion Loan, the Trustee or a
Custodian on its behalf shall continuously update such exception report to
reflect receipt of any additional documents or instruments or evidence of
recording or filing of such additional documents or instruments with respect to
such Mortgage Loan or Companion Loan, until the earliest of (i) the date on
which such exceptions are eliminated and any such recording or filing has been
completed, (ii) the date on which the affected Mortgage Loan or Companion Loan
has been removed from the Trust Fund, and (iii) the date which is two years
after the Closing Date, and shall provide such updated exception report
(beginning 150 days after the Closing Date and continuing every 90 days
thereafter until the date which is two years after the Closing Date) to each of
the Depositor, the Master Servicer, the Special Servicer, the Majority
Certificateholder of the Controlling Class and, upon request, any
Certificateholder. At any time after the date which is two years after the
Closing Date, the Depositor, the Master Servicer, the Special Servicer and any
Certificateholder may receive, upon request, an updated exception report.

                  (c) The Trustee or a Custodian on its behalf shall review each
of the Mortgage Loan and Companion Loan documents received thereby subsequent to
the Closing Date; and, on or about the first anniversary of the Closing Date,
the Trustee shall certify in writing in the form attached hereto as Schedule III
to each of the Depositor, the Master Servicer, the Special

                                       66
<PAGE>

Servicer, the Majority Certificateholder of the Controlling Class, any related
Class S Certificateholder and each Mortgage Loan Seller that, as to each
Mortgage Loan or Companion Loan listed on the Mortgage Loan Schedule (other than
any Mortgage Loan or Companion Loan as to which a Liquidation Event has
occurred) and except as specifically identified in any exception report annexed
to such certification, (i) all documents specified in clauses (1) through (5),
(9), (11) and (12) (in the case of clause (11), without regard to whether such
UCC financing statements were in the possession of the Mortgage Loan Seller (or
its agent)) of the definition of "Mortgage File" are in its possession or the
related Mortgage Loan Seller has otherwise satisfied the delivery requirements
in accordance with Section 2.01(b), (ii) it or a Custodian on its behalf has
received either a recorded original of each of the assignments specified in
clauses (3) and, insofar as an unrecorded original thereof had been delivered or
caused to be delivered by the related Mortgage Loan Seller, (5) of the
definition of "Mortgage File" or a copy of such recorded original certified by
the applicable public recording office to be true and complete and (iii) all
Mortgage Loan and Companion Loan documents received by it or any Custodian have
been reviewed by it or by such Custodian on its behalf and (A) appear regular on
their face and relate to such Mortgage Loan or Companion Loan, (B) appear to
have been executed (where appropriate) and (C) purport to relate to such
Mortgage Loan or Companion Loan.

                  (d) It is acknowledged that neither the Trustee nor any
Custodian is under any duty or obligation (i) to determine whether any of the
documents specified in clauses (6), (7), (8), (10), (13), (14), (15), (16) and
(17) of the definition of "Mortgage File" exist or are required to be delivered
by the Depositor, any Mortgage Loan Seller or any other Person or (ii) to
inspect, review or examine any of the documents, instruments, certificates or
other papers relating to the Mortgage Loans and Companion Loans delivered to it
to determine that the same are genuine, enforceable, in recordable form or
appropriate for the represented purpose or that they are other than what they
purport to be on their face.

                  (e) If, in the process of reviewing the Mortgage Files or at
any time thereafter, the Trustee or any Custodian finds (or, if at any time, any
other party hereto finds) any document or documents constituting a part of a
Mortgage File to have not been properly executed or, subject to Section 2.01(b),
to have not been delivered, to contain information that does not conform in any
material respect with the corresponding information set forth in the Mortgage
Loan Schedule, or to be defective on its face (each, a "Defect" in the related
Mortgage File) the Trustee (or such other party) shall promptly so notify each
of the other parties hereto and the related Mortgage Loan Seller. If and when
notified of any error in the Mortgage Loan Schedule, the Depositor shall
promptly correct such error and distribute a new, corrected Mortgage Loan
Schedule to each of the other parties hereto, and upon receipt by the Trustee of
such a corrected Mortgage Loan Schedule so identified, such new, corrected
Mortgage Loan Schedule shall be deemed to amend and replace the existing
Mortgage Loan Schedule for all purposes.

                  SECTION 2.03  Mortgage Loan Sellers' Repurchase of Mortgage
                                Loans and Loan Groups for Defects in Mortgage
                                Files and Breaches of Representations and
                                Warranties.

                  (a) If the Trustee discovers or receives notice of a Defect in
any Mortgage File or a breach of any representation or warranty set forth in or
made pursuant to Section 4(a) of each Mortgage Loan Purchase Agreement or
Section 2(a) of either Supplemental Agreement (a

                                       67
<PAGE>

"Breach"), which Defect or Breach, as the case may be, materially and adversely
affects the value of any Mortgage Loan or Loan Group or the interests of the
Certificateholders therein, or if the Trustee discovers or receives notice of
any event that would give rise to the repurchase of a Mortgage Loan or Loan
Group pursuant to Section 6(b) of any Mortgage Loan Purchase Agreement or
Section 4(b) of either Supplemental Agreement, the Trustee shall give prompt
written notice of such Defect, Breach or event, as the case may be, to the
Depositor, the Master Servicer, the Special Servicer, the Rating Agencies and
the related Mortgage Loan Seller (and GMACCM, in the case of such a Defect,
Breach or event under a Supplemental Agreement) and shall request that the
related Mortgage Loan Seller (or GMACCM, in the case of such a Defect, Breach or
event under the Supplemental Agreement), within the time period provided for in
the related Mortgage Loan Purchase Agreement or Supplemental Agreement, as
applicable, cure such Defect, Breach or event, as the case may be, in all
material respects or repurchase the affected Mortgage Loan or Loan Group at the
applicable Purchase Price in conformity with the related Mortgage Loan Purchase
Agreement or Supplemental Agreement, as applicable; provided, however, that in
lieu of effecting any such repurchase, a Mortgage Loan Seller (or GMACCM, in the
case of such a Defect, Breach or event under the Supplemental Agreement) will be
permitted to deliver a Qualifying Substitute Mortgage Loan until the second
anniversary of the Closing Date and to pay a cash amount equal to the applicable
Substitution Shortfall Amount, subject to the terms and conditions of the
related Mortgage Loan Purchase Agreement or Supplemental Agreement, as
applicable, and this Agreement; provided, further, that if such Defect or Breach
would cause the Mortgage Loan or Loan Group to be other than a "qualified
mortgage" under Section 860G(a)(3) of the Code, such Defect or Breach shall be
cured or the related Mortgage Loan or Loan Group shall be repurchased or
replaced with a Qualifying Substitute Mortgage Loan within 60 days of discovery.
In the case of any Breach, Defect or event with respect to a
Cross-Collateralized Mortgage Loan that requires repurchase of such Mortgage
Loan the Cross-Collateralized Mortgage Loan must be repurchased in its entirety.
Notwithstanding the foregoing, the applicable Mortgage Loan Seller will not be
required to repurchase all of the related Cross-Collateralized Mortgage Loans
if, after giving effect to the repurchase only of the Mortgage Loans or Loans
Group materially and adversely affected by such Breach or Defect, both (i) the
Debt Service Coverage Ratio for the four preceding calendar quarters for all of
the Mortgaged Properties then remaining subject to the related Mortgage is not
less than 0.10x below the Debt Service Coverage Ratio set forth in the
Prospectus with respect to such Cross-Collateralized Mortgage Loan and the
related Cross-Collateralized Mortgage Loans, and (ii) the Loan-to-Value Ratio
for all of the Mortgage Properties then remaining subject to the related
Mortgage is not greater than 10% more than the Loan-to-Value Ratio set forth in
the Prospectus with respect to such Cross-Collateralized Mortgage Loan and the
related Cross-Collateralized Mortgage Loans, in each case determined by the
Master Servicer or Special Servicer, as applicable. If the Master Servicer or
Special Servicer, as applicable determines that an Appraisal is required for
purposes of determining the foregoing, the Appraisal will be at the related
Mortgage Loan Seller's expense, if the scope and cost of the Appraisal is
approved by the related Mortgage Loan Seller (such approval not to be
unreasonably withheld).

                  Unless the applicable delivery requirements are otherwise
deemed to have been satisfied pursuant to Section 2.01(b) (including by virtue
of the delivery of alternative documents as specified in Section 2.01(b)), any
of the following Defects shall be conclusively presumed materially and adversely
to affect the interests of Certificateholders in, and the value of, a Mortgage
Loan: (a) the absence from the Mortgage File of the original signed Mortgage
Note,

                                       68
<PAGE>

unless the Mortgage File contains a signed lost note affidavit that appears to
be regular on its face; (b) the absence from the Mortgage File of the original
signed Mortgage that appears to be regular on its face, unless there is included
in the Mortgage File a certified copy of the Mortgage and a certificate stating
that the original signed Mortgage and any intervening assignments required to
create a complete chain of assignment to the Trustee were sent for recordation;
or (c) the absence from the Mortgage File of the item called for by paragraph
(9) of the definition of Mortgage File. If any of the foregoing Defects (each, a
"Material Document Defect") is discovered by the Trustee, the Trustee will take
the steps described elsewhere in this section.

                  As to any Qualifying Substitute Mortgage Loan or Loans, the
Trustee shall direct the related Mortgage Loan Seller (or GMACCM, in the case of
such a Defect, Breach or event under the Supplemental Agreement) to deliver to
the Trustee for such Qualifying Substitute Mortgage Loan or Loans (with a copy
to the Master Servicer), the related Mortgage File(s) with the related Mortgage
Note(s) endorsed as required by clause (1) of the definition of "Mortgage File".
No substitution may be made in any calendar month after the Determination Date
for such month. Monthly Payments due with respect to Qualifying Substitute
Mortgage Loans in the month of substitution shall not be part of the Trust Fund
and will be retained by Master Servicer and remitted by the Master Servicer to
the related Mortgage Loan Seller (or GMACCM, in the case of such a Defect,
Breach or event under the Supplemental Agreement) on the next succeeding
Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Monthly Payment due on the related Deleted
Mortgage Loan for such month and thereafter the related Mortgage Loan Seller (or
GMACCM, in the case of such a Defect, Breach or event under the Supplemental
Agreement) shall be entitled to retain all amounts received in respect of such
Deleted Mortgage Loan.

                  In any month in which the related Mortgage Loan Seller (or
GMACCM under a Supplemental Agreement) substitutes one or more Qualifying
Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer will determine the applicable Substitution Shortfall Amount. The
Trustee shall direct the related Mortgage Loan Seller (or GMACCM, as applicable)
to deposit cash equal to the applicable portion of such amount into the
applicable Distribution Account concurrently with the delivery of the Mortgage
File(s) for the Qualifying Substitute Mortgage Loan(s), without any
reimbursement thereof. The Trustee shall also direct the related Mortgage Loan
Seller (or GMACCM, as applicable) to give written notice to the Trustee and the
Master Servicer of such deposit, accompanied by an Officers' Certificate as to
the calculation of the applicable Substitution Shortfall Amount. The Trustee
shall direct the related Mortgage Loan Seller (or GMACCM, as applicable) to
amend the Mortgage Loan Schedule to reflect the removal of each Deleted Mortgage
Loan and, if applicable, the substitution of the Qualifying Substitute Mortgage
Loan(s); and, upon such amendment, the Trustee shall deliver or cause the
delivery of such amended Mortgage Loan Schedule to the other parties hereto.
Upon any such substitution, the Qualifying Substitute Mortgage Loan(s) shall be
subject to the terms of this Agreement in all respects.

                  (b) In connection with any repurchase of or substitution for a
Mortgage Loan or Loan Group contemplated by this Section 2.03, the Trustee, the
Master Servicer and the Special Servicer shall each tender promptly to the
related Mortgage Loan Seller (or GMACCM, as applicable), upon delivery to each
of the Trustee, the Master Servicer and the Special Servicer of a trust receipt
executed by the related Mortgage Loan Seller (or GMACCM, as applicable), all

                                       69
<PAGE>

portions of the Mortgage File and other documents pertaining to such Mortgage
Loan or Loan Group possessed by it, and each document that constitutes a part of
the related Mortgage File that was endorsed or assigned to the Trustee shall be
endorsed or assigned, as the case may be, to the related Mortgage Loan Seller
(or GMACCM, as applicable) in the same manner as provided in Section 2 of each
Mortgage Loan Purchase Agreement. Additionally, in connection with any
repurchase of or substitution for a Mortgage Loan or Loan Group pursuant to this
Section 2.03, the Master Servicer shall release or cause to be released to the
related Mortgage Loan Seller (or GMACCM, as applicable) any Reserve Funds or
Escrow Payments with respect to the related Mortgage Loan or Loan Group. If the
affected Mortgage Loan or Loan Group is to be repurchased, the Trustee shall
designate the Collection Account as the account to which funds in the amount of
the Purchase Price are to be wired. The Trustee shall notify any related Class S
Certificateholder of any repurchase or substitution regarding any related
Companion Loan.

                  (c) Section 6 of the related Mortgage Loan Purchase Agreement
and Section 4 of each Supplemental Agreement provides the sole remedy available
to the Certificateholders, or the Trustee on behalf of the Certificateholders,
respecting any Defect in a Mortgage File or any Breach of any representation or
warranty set forth in or required to be made pursuant to Section 4(a) of such
Mortgage Loan Purchase Agreement or Section 2(a) of such Supplemental Agreement
or any of the circumstances described in Section 6(b) of such Mortgage Loan
Purchase Agreement or in Section 4(b) of such Supplemental Agreement.

                  (d) The Trustee shall, for the benefit of the
Certificateholders, enforce the obligations of each Mortgage Loan Seller under
Section 6 of the related Mortgage Loan Purchase Agreement and the obligations of
GMACCM under Section 4 of each Supplemental Agreement. Such enforcement,
including, without limitation, the legal prosecution of claims, shall be carried
out in such form, to such extent and at such time as the Trustee would require
were it, in its individual capacity, the owner of the affected Mortgage Loan(s)
or Companion Loan(s). The Trustee shall be reimbursed for the reasonable costs
of such enforcement, together with interest thereon at the Reimbursement Rate:
first, from a specific recovery of costs, expenses or attorneys' fees against
the related Mortgage Loan Seller (or GMACCM, in the case of enforcement under a
Supplemental Agreement); second, pursuant to Section 3.05(a)(ix) out of the
related Purchase Price, to the extent that such expenses are a specific
component thereof; and third, if at the conclusion of such enforcement action it
is determined that the amounts described in clauses first and second are
insufficient, then pursuant to Section 3.05(a)(x) out of general collections on
the Mortgage Loans on deposit in the Collection Account.

                  (e) Notwithstanding anything to the contrary in this Section
2.03, with respect to any repurchase of the Mortgage Loan identified on the
Mortgage Loan Schedule as Loan Number 24082 ("Arizona Mills Loan"), subject to
and in accordance with the terms and conditions of the GMACCM Mortgage Loan
Purchase Agreement and the Goldman Sachs Mortgage Company Mortgage Loan Purchase
Agreement, if pursuant to this Section 2.03, either the interest in the Arizona
Mills Loan conveyed under the GMACCM Mortgage Loan Purchase Agreement or the
interest in the Arizona Mills Loan conveyed under the Goldman Sachs Mortgage
Company Mortgage Loan Purchase Agreement is required to be repurchased, the
Trustee shall cause both such interests to be repurchased concurrently by the
respective Mortgage Loan Sellers pursuant to this Section 2.03. The applicable
Mortgage Loan Sellers will

                                       70
<PAGE>

maintain the right to deliver a Qualifying Substitute Mortgage Loan in lieu of
repurchase as described in this Section 2.03 with respect to their respective
interests in the Arizona Mills Loan.

                  SECTION 2.04  Issuance of Class R-I Certificates; Creation of
                                REMIC I Regular Interests.

                  Concurrently with the assignment to the Trustee of the assets

Depositor, the REMIC I Regular Interests have been issued hereunder and the
Trustee has executed, and caused the Certificate Registrar to authenticate and

II to receive distributions from the proceeds of REMIC I in respect of the Class

                  SECTION 2.05  Conveyance of REMIC I Regular Interests;
                                Acceptance of REMIC II by the Trustee.

                  The Depositor, as of the Closing Date, and concurrently with
the execution and delivery hereof, does hereby assign without recourse all the
right, title and interest of the Depositor in and to the REMIC I Regular
Interests to the Trustee for the benefit of the Class R-II Certificateholders
and REMIC III as holder of the REMIC II Regular Interests. The Trustee
acknowledges the assignment to it 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-II Certificateholders and REMIC III as the
holder of the REMIC II Regular Interests.

the REMIC II Regular Interests have been issued hereunder and the Trustee has
executed, and caused the Certificate Registrar to authenticate and deliver, to

of REMIC II. The rights of the Class R-II Certificateholders and REMIC III to
receive distributions from the proceeds of REMIC II in respect of the Class R-II
Certificates and the REMIC II Regular Interests, respectively, and all ownership
interests of the Class R-II Certificateholders and REMIC III in and to such

                  The Depositor, as of the Closing Date, and concurrently with
the execution and delivery hereof, does hereby assign without recourse all the
right, title and interest of the Depositor in and to the REMIC II Regular
Interests to the Trustee for the benefit of the REMIC

                                  ARTICLE III

                        ADMINISTRATION AND THE SERVICING
                                OF THE TRUST FUND

                  SECTION 3.01  Servicing and Administration of the Mortgage
                                Loans and Companion Loans.

                  (a) Each of the Master Servicer and the Special Servicer shall
service and administer the Mortgage Loans and Companion Loans that it is
obligated to service and administer pursuant to this Agreement on behalf of the
Trustee and in the best interests of and for the benefit of the
Certificateholders (as determined by the Master Servicer or the Special
Servicer, as the case may be, in its good faith and reasonable judgment), in
accordance with applicable law, the terms of this Agreement and the terms of the
respective Mortgage Loans or Companion Loans as the case may be (and in the case
of the Loan Groups, the related Intercreditor Agreement) and, to the extent
consistent with the foregoing, further as follows: (i) with the same care, skill
and diligence as is normal and usual in its general mortgage servicing and REO
property management activities on behalf of third parties or on behalf of
itself, whichever is higher, with respect to mortgage loans and REO properties
that are comparable to those for which it is responsible hereunder; (ii) with a
view to the timely collection of all scheduled payments of principal and
interest under the Mortgage Loans and Companion Loans or, if a Mortgage Loan or
Companion Loan comes into and continues in default and if, in the good faith and
reasonable judgment of the Special Servicer, no satisfactory arrangements can be
made for the collection of the delinquent payments, the maximization of the
recovery on such Mortgage Loan or Companion Loan to the Certificateholders (as a
collective whole) on a present value basis (the relevant discounting of
anticipated collections that will be distributable to Certificateholders to be
performed at the related Net Mortgage Rate); and (iii) without regard to (A) any
relationship that the Master Servicer or the Special Servicer, as the case may
be, or any Affiliate thereof may have with the related Mortgagor, (B) the
ownership of any Certificate by the Master Servicer or the Special Servicer, as
the case may be, or by any Affiliate thereof, (C) the Master Servicer's
obligation to make Advances, (D) the Special Servicer's obligation to make (or
to direct the Master Servicer to make) Servicing Advances, (E) the right of the
Master

                                       72
<PAGE>

Servicer (or any Affiliate thereof) or the Special Servicer (or any Affiliate
thereof), as the case may be, to receive reimbursement of costs, or the
sufficiency of any compensation payable to it, hereunder or with respect to any
particular transaction and (F) the obligation of GMACCM, as a Mortgage Loan
Seller, to repurchase Mortgage Loans and Companion Loans pursuant to Section
6(b) of the Mortgage Loan Purchase Agreement or Section 4(b) of either
Supplemental Agreement (the conditions set forth in the immediately foregoing
clauses (i), (ii) and (iii), the "Servicing Standard"). Each of the Master
Servicer and Special Servicer shall also service and administer each of the
Companion Loans in accordance with its related Intercreditor Agreement. Without
limiting the generality of the foregoing, each of the Master Servicer and the
Special Servicer, in its own name, in connection with its servicing and
administrative duties hereunder is hereby authorized and empowered by the
Trustee to exercise efforts consistent with the foregoing standard and to
execute and deliver, on behalf of the Certificateholders and the Trustee or any
of them, any and all financing statements, continuation statements and other
documents or instruments necessary to maintain the lien created by any Mortgage
or other security document in the related Mortgage File on the related Mortgaged
Property and related collateral; subject to Section 3.20, any and all
modifications, waivers, amendments or consents to or with respect to any
documents contained in the related Mortgage File; and any and all instruments of
satisfaction or cancellation, or of full release or discharge, and all other
comparable instruments, with respect to the Mortgage Loans, Companion Loans and
the Mortgaged Properties. Each of the Master Servicer and the Special Servicer
is also authorized to approve a request by a Mortgagor under a Mortgage Loan or
Companion Loan that it is obligated to service and administer pursuant to this
Agreement, for an easement, consent to alteration or demolition, and for other
similar matters, provided that the Master Servicer or the Special Servicer, as
the case may be, determines, exercising its good faith business judgment and in
accordance with the Servicing Standard, that such approval will not affect the
security for, or the timely and full collectability of, the related Mortgage
Loan or Companion Loan. Subject to Section 3.10, the Trustee shall furnish, or
cause to be furnished, to the Master Servicer and the Special Servicer any
powers of attorney and other documents necessary or appropriate to enable the
Master Servicer or the Special Servicer, as the case may be, to carry out its
servicing and administrative duties hereunder; provided, however, that the
Trustee shall not be held liable, and shall be indemnified by the Master
Servicer or the Special Servicer, as applicable, for any negligence with respect
to, or misuse of, any such power of attorney by the Master Servicer or the
Special Servicer, as the case may be; and further provided that neither the
Master Servicer nor the Special Servicer, without the Trustee's written consent,
shall initiate any action in the Trustee's name without indicating its
representative capacity or cause the Trustee to be registered to do business in
any state.

                  (b) Subject to Section 3.01(a), the Master Servicer and the
Special Servicer each shall have full power and authority, acting alone or,
subject to Section 3.22, through Sub-Servicers, 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.

                  (c) The relationship of the Master Servicer and the Special
Servicer to the Trustee and, unless the same Person acts in both capacities, to
each other under this Agreement is intended by the parties to be that of an
independent contractor and not that of a joint venturer, partner or agent.
Unless the same Person acts in both capacities, the Master Servicer shall have
no responsibility for the performance by the Special Servicer of its duties
under this Agreement,

                                       73
<PAGE>

and the Special Servicer shall have no responsibility for the performance of the
Master Servicer under this Agreement.

                  (d) Subject to Section 3.01(a), each of the Master Servicer
and Special Servicer shall service and administer each Mortgage Loan or Loan
Group that is a Cross-Collateralized Mortgage Loan as a single Mortgage Loan as
and when it deems such treatment necessary and appropriate.

                  (e) The parties hereto acknowledge that each Loan Group is
subject to the terms and conditions of the related Intercreditor Agreement. With
respect to each Loan Group, the parties hereto recognize the respective rights
and obligations of the noteholders under the related Intercreditor Agreement,
including with respect to the allocation of collections on or in respect of such
Loan Group in accordance with Sections 3 or 4 of such Intercreditor Agreement
and the making of payments to the noteholders in accordance with Section 7 of
such Intercreditor Agreement. The Master Servicer assumes the obligations of
servicer under each Intercreditor Agreement and, if such Loan Group is then
being specially serviced, the Special Servicer assumes the obligations of
servicer under each Intercreditor Agreement. In the event of any inconsistency
between the provisions of an Intercreditor Agreement and the provisions of this
Agreement relating to the rights and obligations of the Trustee, as holder of
the related Mortgage Loan and Companion Loan, this Agreement shall control with
respect to such Loan Group.

                  SECTION 3.02  Collection of Mortgage Loan and Companion Loan
                                Payments.

                  The Master Servicer (or the Special Servicer with respect to
the Specially Serviced Mortgage Loans) shall make reasonable efforts to collect
all payments called for under the terms and provisions of the Mortgage Loans and
Companion Loans (as the case may be), and shall, to the extent such procedures
shall be consistent with this Agreement and the terms and conditions of the
Mortgage Loans and Companion Loans, follow such collection procedures as are
consistent with the Servicing Standard; provided, however, that nothing herein
contained shall be construed as an express or implied guarantee by the Master
Servicer or the Special Servicer of the collectability of the Mortgage Loans and
Companion Loans. Consistent with the foregoing, the Master Servicer may in its
discretion waive any Penalty Charge in connection with any delinquent payment on
a Mortgage Loan or Companion Loan (other than a Specially Serviced Mortgage
Loan) and the Special Servicer may in its discretion waive any Penalty Charge in
connection with any delinquent payment on a Specially Serviced Mortgage Loan.

                  SECTION 3.03  Collection of Taxes, Assessments and Similar
                                Items; Servicing Accounts and Reserve Accounts.

                  (a) Each of the Master Servicer (or the Special Servicer with
respect to the Specially Serviced Mortgage Loans) shall establish and maintain
one or more accounts (the "Servicing Accounts"), into which all Escrow Payments
shall be deposited and retained. Servicing Accounts shall be Eligible Accounts.
Withdrawals of amounts so collected in respect of any Mortgage Loan or Companion
Loan (and interest earned thereon) from a Servicing Account may be made only to:
(i) effect payment of real estate taxes, assessments, insurance premiums, ground
rents (if applicable) and comparable items in respect of the related Mortgaged
Property; (ii) reimburse the Fiscal Agent, the Trustee, the Master Servicer and
the Special

                                       74
<PAGE>

Servicer, in that order, as applicable, for any unreimbursed Servicing Advances
made thereby to cover any of the items described in the immediately preceding
clause (i); (iii) refund to the related Mortgagor any sums as may be determined
to be overages; (iv) pay interest, if required and as described below, to the
related Mortgagor on balances in the Servicing Account (or, if and to the extent
not payable to the related Mortgagor, to pay such interest to the Master
Servicer or Special Servicer, as applicable); (v) disburse Insurance Proceeds if
required to be applied to the repair or restoration of the related Mortgaged
Property; or (vi) clear and terminate the Servicing Account at the termination
of this Agreement in accordance with Section 9.01. As part of its servicing
duties, the Master Servicer and the Special Servicer shall pay or cause to be
paid to the Mortgagors interest on funds in Servicing Accounts maintained
thereby, to the extent required by law or the terms of the related Mortgage Loan
or Companion Loan. The Servicing Accounts shall not be considered part of the
segregated pool of assets constituting REMIC I, REMIC II, REMIC III or the
Grantor Trust.

                  (b) Each of the Master Servicer (with respect to Mortgage
Loans and Companion Loans other than Specially Serviced Mortgage Loans) and the
Special Servicer (with respect to the Specially Serviced Mortgage Loans) shall
(i) maintain accurate records with respect to each related Mortgaged Property
reflecting the status of real estate taxes, assessments and other similar items
that are or may become a lien thereon and the status of insurance premiums and
any ground rents payable in respect thereof, and (ii) use reasonable efforts to
obtain, from time to time, all bills for the payment of such items (including
renewal premiums) for Mortgage Loans and Companion Loans which require the
related Mortgagor to escrow for the payment of such items and shall effect
payment thereof prior to the applicable penalty or termination date, employing
for such purpose Escrow Payments as allowed under the terms of the related
Mortgage Loan or Companion Loan. To the extent that a Mortgage Loan or Companion
Loan does not require a Mortgagor to escrow for the payment of real estate
taxes, assessments, insurance premiums, ground rents (if applicable) and similar
items, the Master Servicer (or the Special Servicer with respect to the
Specially Serviced Mortgaged Loans) shall use reasonable efforts consistent with
the Servicing Standard to cause the related Mortgagor to comply with the
requirements of the related Mortgage for payments in respect of such items at
the time they first become due.

                  (c) In accordance with the Servicing Standard, the Master
Servicer (at the direction of the Special Servicer in the case of Specially
Serviced Mortgage Loans) shall advance with respect to each related Mortgaged
Property all such funds as are necessary for the purpose of effecting the
payment of (i) real estate taxes, assessments and other similar items that are
or may become a lien thereon, (ii) ground rents (if applicable), and (iii)
premiums on Insurance Policies, in each instance if and to the extent Escrow
Payments collected from the related Mortgagor are insufficient to pay such item
when due and the related Mortgagor has failed to pay such item on a timely
basis, and provided that the particular advance would not, if made, constitute a
Nonrecoverable Servicing Advance. All such Servicing Advances shall be
reimbursable in the first instance from related collections from the Mortgagors,
and further as provided in Section 3.05. No costs incurred by the Master
Servicer or the Special Servicer in effecting the payment of real estate taxes,
assessments, ground rents (if applicable) and other similar items on or in
respect of the Mortgaged Properties shall, for purposes hereof, including,
without limitation, calculating monthly distributions to Certificateholders, be
added to the unpaid

                                       75
<PAGE>

principal balances of the related Mortgage Loans or Companion Loans,
notwithstanding that the terms of such Mortgage Loans or Companion Loans so
permit.

                  (d) The Master Servicer (or the Special Servicer with respect
to Specially Serviced Mortgage Loans) shall, establish and maintain, as
applicable, one or more accounts (the "Reserve Accounts"), into which all
Reserve Funds, if any, shall be deposited and retained. Withdrawals of amounts
so deposited may be made to pay for, or to reimburse the related Mortgagor in
connection with, the related repairs, environmental remediation, replacements
and/or capital improvements at the related Mortgaged Property if such repairs,
environmental remediation, replacements and/or capital improvements have been
completed, and such withdrawals are made, in accordance with the Servicing
Standard and the terms of the related Mortgage Note, Mortgage and any agreement
with the related Mortgagor governing such Reserve Funds. Subject to the terms of
the related Mortgage Note and Mortgage, all Reserve Accounts shall be Eligible
Accounts. As part of its servicing duties, the Master Servicer and the Special
Servicer shall pay or cause to be paid to the Mortgagors interest on funds in
the Reserve Accounts maintained thereby, to the extent required by applicable
law or the terms of the related Mortgage Loan or Companion Loan. The Reserve
Accounts shall not be considered part of the segregated pool of assets
comprising REMIC I, REMIC II, REMIC III or the Grantor Trust.

                  SECTION 3.04  Collection Account, Distribution Accounts,
                                Excess Liquidation Proceeds Reserve Account and
                                Interest Reserve Account.

                  (a) The Master Servicer shall establish and maintain a
Collection Account that shall be held in the name of the Master Servicer on
behalf of the Certificateholders and shall consist of a Mortgage Loan Subaccount
and, with respect to each Companion Loan, a Companion Subaccount. In lieu of
establishing a separate Companion Subaccount with respect to each Companion
Loan, the Master Servicer may establish one Companion Subaccount for deposit of
amounts allocable to Class S Certificateholders provided that the Master
Servicer maintains adequate books and records to account for the separate
entitlements of each Companion Loan. The Master Servicer shall deposit or cause
to be deposited into the Collection Account on a daily basis, except as
otherwise specifically provided herein, the following payments and collections
received or made by or on behalf of it subsequent to the Cut-off Date (other
than in respect of principal and interest on the Mortgage Loans and Companion
Loans due and payable on or before the Cut-off Date), and payments (other than
Principal Prepayments) received by it on or prior to the Cut-off Date but
allocable to a period subsequent thereto:

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

                          (ii) all payments on account of interest (including,
             without limitation, Default Interest and Excess Interest) on the
             Mortgage Loans and Companion Loans, late payment charges and
             Prepayment Premiums;

                          (iii) any amounts received from the Special Servicer
             which are required to be transferred from the REO Account pursuant
             to Section 3.16(c) and amounts of interest and investment income
             earned in respect of amounts relating to the Trust Fund held in any
             Lock-Box Account or Cash Collateral Account, if any, and only to
             the extent

                                       76
<PAGE>

             not required to be paid to the applicable Mortgagor under the terms
             of the related Mortgage Loan and Companion Loan documents or
             applicable law;

                          (iv) all Insurance Proceeds and Liquidation Proceeds
             received in respect of any Mortgage Loan, Companion Loan or REO
             Property (other than Excess Liquidation Proceeds and Liquidation
             Proceeds that are received in connection with the Master Servicer's
             or the Depositor's purchase of all the Mortgage Loans, any
             Companion Loans and any REO Properties in the Trust Fund and that
             are to be deposited in the applicable Distribution Account pursuant
             to Section 9.01) and any Borrower Recoveries;

                          (v) any amounts required to be deposited by the Master
             Servicer pursuant to Section 3.06 in connection with losses
             incurred with respect to Permitted Investments of funds relating to
             the Trust Fund held in the Collection Account;

                          (vi) that portion of each Delinquency Advance that
             represents (without duplication) the Servicing Fee; and

                          (vii) any amounts required to be deposited by the
             Master Servicer or the Special Servicer pursuant to Section 3.07(b)
             in connection with losses resulting from a deductible clause in a
             blanket hazard policy.

                  The foregoing requirements for deposit in the Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, actual payments from Mortgagors in the
nature of Escrow Payments, Reserve Funds, charges for beneficiary statements or
demands, assumption fees, amounts collected for mortgagor checks returned for
insufficient funds, ancillary fees and any other amounts that the Master
Servicer and the Special Servicer are entitled to as additional servicing
compensation pursuant to Section 3.11 need not be deposited by the Master
Servicer in the Collection Account. If 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. The Master Servicer shall promptly deliver to
the Special Servicer as additional servicing compensation in accordance with
Section 3.11(d), assumption fees, modification fees, ancillary fees and other
transaction fees due to and received by the Master Servicer with respect to
Specially Serviced Mortgage Loans. The Collection Account shall be maintained as
a segregated account, separate and apart from trust funds created for mortgage
pass-through certificates of other series serviced and the other accounts of the
Master Servicer.

                  Upon receipt of any of the amounts described in clauses (i),
(ii) and (iv) above with respect to any Mortgage Loan or Companion Loan which is
not an REO Loan, the Special Servicer shall promptly, but in no event later than
two Business Days after receipt, remit such amounts to the Master Servicer for
deposit into the Collection Account in accordance with the second preceding
paragraph, unless the Special Servicer determines, consistent with the Servicing
Standard, that a particular item should not be deposited because of a
restrictive endorsement or other appropriate reason. Any such amounts received
by the Special Servicer with respect to an REO Property shall be deposited by
the Special Servicer into the REO Account and remitted to the Master Servicer
for deposit into the Collection Account pursuant to Section 3.16(c). With
respect to any such amounts paid by check to the order of the Special

                                       77
<PAGE>

Servicer, the Special Servicer shall endorse such check to the order of the
Master Servicer and shall deliver promptly, but in no event later than two
Business Days after receipt, any such check to the Master Servicer by overnight
courier, unless the Special Servicer determines, consistent with the Servicing
Standard, that a particular item cannot be so endorsed and delivered because of
a restrictive endorsement or other appropriate reason.

                  Funds in the Collection Account may be invested only in
Permitted Investments in accordance with the provisions of Section 3.06. The
Master Servicer shall give notice to the Trustee, the Special Servicer and the
Depositor of the location of the Collection Account as of the Closing Date and
of the new location of the Collection Account promptly after any change thereto.

                  (b) On each Master Servicer Remittance Date, the Master
Servicer shall, with respect to each Mortgage Loan and Companion Loan and prior
to making the allocations between the Mortgage Loan Subaccount and the related
Companion Subaccount, if any, pursuant to Section 3.04(c):

                          (i) withdraw from the Collection Account any sums
             deposited therein in error and pay such sums to the Persons
             entitled thereto;

                          (ii) pay itself, as additional servicing compensation
             in accordance with Section 3.11(b), (A) interest and investment
             income earned in respect of amounts relating to the Trust Fund held
             in the Collection Account, any Lock-Box Account and Cash Collateral
             Account as provided in Section 3.06(b) (but only to the extent of
             the Net Investment Earnings with respect to the Collection Account,
             any Lock-Box Account and Cash collateral Account for any collection
             Period) and (B) Prepayment Interest Excesses and Balloon Payment
             Interest Excess received on the Mortgage Loan and, if such Mortgage
             Loan is a Companion Loan, allocable to the holder of such Companion
             Loan in accordance with Section 3 or 4 of the Intercreditor
             Agreement; to reimburse itself or the Trustee, as the case may be,
             for any unreimbursed expenses reasonably incurred by such Person in
             respect of any Breach or Defect with respect to such Mortgage Loan
             or Loan Group giving rise to a repurchase obligation on the part of
             a Mortgage Loan Seller pursuant to Section 6 of the related
             Mortgage Loan Purchase Agreement or by GMACCM pursuant to Section 4
             of either Supplemental Agreement, including, without limitation,
             any expenses arising out of the enforcement of the repurchase
             obligation, together with interest thereon at the Reimbursement
             Rate, each such Person's right to reimbursement pursuant to this
             clause (ii) with respect to such Mortgage Loan or Loan Group being
             limited to that portion of the Purchase Price paid for such
             Mortgage Loan or Loan Group that represents such expense in
             accordance with clause (d) of the definition of Purchase Price; and

                          (iii) to pay itself, the Special Servicer, GMACCM, the
             Majority Certificateholder of the Controlling Class or the related
             Class S Certificateholder, as the case may be, with respect to each
             Mortgage Loan or Loan Group, if any, previously purchased by such
             Person pursuant to or as contemplated by this Agreement, all
             amounts received on such Mortgage Loan or Loan Group subsequent to
             the date of purchase.

Mortgage Loan Subaccount the following amounts from funds on deposit in the
Collection Account with respect to such Mortgage Loan or Loan Group:

                  of principal and interest on each Mortgage Loan or Loan Group,
                  but, in the case of a Loan Group, only to the extent allocable
                  to the Mortgage Loan therein pursuant to the terms of Section
                  3 or 4 of the Intercreditor Agreement, whether received in the
                  form of Monthly Payments, Balloon Payments, Principal
                  Prepayments, Liquidation Proceeds or Insurance Proceeds;

                           (B) the Purchase Price received in connection with
                  any purchase of a Mortgage Loan (but not any related Companion
                  Loan) by a Mortgage Loan Seller pursuant to Section 6 of the
                  related Mortgage Loan Purchase Agreement or by GMACCM pursuant
                  to Section 4 of either Supplemental Agreement or any purchase
                  of a Mortgage Loan (but not the related Companion Loan)
                  pursuant to Section 3.18 or 9.01; and

                           (C) any Borrower Recoveries in respect of such
                  Mortgage Loan not allocable to any Class S Certificateholder

             respect to such Companion Loan:

                           (A) except for amounts allocated as provided in
                  clause (B) below all payments received on account of principal

                  extent of any Borrower Recoveries in respect of such Companion
                  Loan, if either (x) such Companion Loan is not a Specially
                  Serviced Mortgage Loan and no monetary event of default has
                  occurred and is continuing under the related Loan Group
                  mortgage loan documents or (y) all principal, interest and all
                  other amounts due to the Trust Fund in respect of such

                  (II) any other item of expense previously paid pursuant to

<PAGE>

                            (iii) In making the foregoing deposits into the
                  Collection Account and the allocations of amounts received
                  with respect to any Companion Loan between the Mortgage Loan
                  Subaccount and the Companion Subaccount, if the Special
                  Servicer, in connection with a Workout of such Loan Group,
                  has modified the terms thereof such that (i) the related
                  Mortgage Note Principal Balance is decreased, (ii) the
                  Mortgage Rate or scheduled amortization payments on the
                  related Mortgage Note are reduced, (iii) payments of interest
                  or principal on such Mortgage Note are waived, reduced or

                  Loan Subaccount and Companion Subaccount pursuant to this
                  Section 3.04 shall be made as though such Workout did not
                  occur, with the payment terms of the related Mortgage Loan or
                  Companion Loan remaining the same as they are on the date
                  hereof, and the related Companion Loan (and, as a result, the
                  related Companion Subaccount) shall bear all waivers,
                  reductions or deferrals of amounts due on such Loan Group and
                  the related Mortgage Notes attributable to such Workout (up
                  to the amount of the amounts distributable to the related
                  Class S Certificateholder from amounts on deposit in the
                  Companion Subaccount).

                  (d) (i) The Trustee shall establish and maintain a Companion
Loan Distribution Account for the benefit of each respective class of Class S
Certificateholder. Any Companion Loan Distribution Account shall be maintained
as a segregated account or subaccount, separate and apart from other accounts
administered by the Trustee. The Trustee may establish a single Companion Loan
Distribution Account for deposit of amounts distributable to Class S
Certificateholders; provided that it shall maintain adequate books and records
with respect to all amounts on deposit from time to time in the Companion Loan
Distribution Account identifying the Companion Loan to which all such deposits
relate. The Trustee shall have the exclusive right to withdraw funds from the
Companion Loan Distribution Account.

                  The Master Servicer shall deliver to the Trustee each month on
or before the Master Servicer Remittance Date therein, for deposit in the
applicable Companion Loan Distribution Account, that portion of the Available
Class S Distribution Amount for the related Companion Loan (calculated without
regard to clauses (b)(iii) or (b)(iv) of the definition thereof) for the related
Distribution Date then on deposit in the related Companion Subaccount together
with any Trustee Fees payable with respect to such Companion Loan to the extent

Proceeds Reserve Account and the Interest Reserve Account) 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 the Master Servicer, the Special Servicer or the
         Trustee, as the case may be, that such Permitted Investment would not
         constitute a Permitted Investment in respect of funds thereafter on
         deposit in the Investment Account.

                  (b) Whether or not the Master Servicer directs the investment
of funds in the Collection Account, and to the extent the Master Servicer
directs the investment of funds in any Lock-Box Account or any Cash Collateral
Account, interest and investment income realized on funds deposited in each such
Investment Account, to the extent of the Net Investment Earnings, if any, with
respect to such account for each Collection Period, shall be for the sole and
exclusive

                                       91

benefit of the Master Servicer and shall be subject to its withdrawal, or
withdrawal at its direction, in accordance with Section 3.05(a). Interest and
investment income realized on funds deposited in the Certificate Distribution
Account, the Companion Loan Distribution Account, the Excess Liquidation
Proceeds Reserve Account and the Interest Reserve Account, to the extent of Net
Investment Earnings, if any, with respect to such account for each Collection
Period, shall be for the sole and exclusive benefit of the Trustee and shall be
subject to its withdrawal in accordance with Section 3.05(b) or (c), as the case
may be. Whether or not the Special Servicer directs the investment of funds in
the REO Account, interest and investment income realized on funds deposited
therein, to the extent of the Net Investment Earnings, if any, for such
Investment Account for each Collection Period, shall be for the sole and
exclusive benefit of the Special Servicer and shall be subject to its withdrawal
in accordance with Section 3.16(b). If any loss shall be incurred in respect of
any Permitted Investment on deposit in the Collection Account, and to the extent
the Master Servicer has discretion to direct the investment of funds in any
Lock-Box Account or any Cash Collateral Account for its sole and exclusive
benefit, the Master Servicer shall deposit therein, no later than the end of the
Collection Period during which such loss was incurred, without right of
reimbursement, the amount of the Net Investment Loss, if any, with respect to
such account for such Collection Period. If any loss shall be incurred in
respect of any Permitted Investment on deposit in the Certificate Distribution
Account, the Companion Loan Distribution Account, the Excess Liquidation
Proceeds Reserve Account or the Interest Reserve Account, the Trustee shall
immediately deposit therein, without right of reimbursement, the amount of the
Net Investment Loss, if any, with respect to such account. If any loss shall be
incurred in respect of any Permitted Investment on deposit in the REO Account,
the Special Servicer shall promptly deposit therein from its own funds, without
right of reimbursement, no later than the end of the Collection Period during
which such loss was incurred, the amount of the Net Investment Loss, if any, for
such Collection Period

                  (c) 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 Trustee may and, subject to Section 8.02, upon the
request of Holders of Certificates entitled to a majority of the Voting Rights
allocated to any Class shall take such action as may be appropriate to enforce
such payment or performance, including the institution and prosecution of
appropriate proceedings.

                  SECTION 3.07  Maintenance of Insurance Policies; Errors and
                                Omissions and Fidelity Coverage.

                  (a) Each of the Master Servicer (in the case of Mortgage Loans
and Companion Loans other than Specially Serviced Mortgage Loans) and the
Special Servicer (in the case of Specially Serviced Mortgage Loans) shall use
reasonable efforts to cause each Mortgagor to maintain in respect of the related
Mortgaged Property all insurance coverage as is required under the related
Mortgage; provided that if any Mortgage permits the holder thereof to dictate to
the Mortgagor the insurance coverage to be maintained on such Mortgaged
Property, the Master Servicer or the Special Servicer, as appropriate, shall
impose such insurance requirements as are consistent with the Servicing
Standard. If a Mortgagor fails to maintain such insurance, the Master Servicer
(at the direction of the Special Servicer in the case of a Specially Serviced
Loan) shall (to the extent available at commercially reasonable terms) obtain
such insurance (which may be through a master or single interest policy) and the
cost (including any

                                       92
<PAGE>

deductible relating to such insurance) of such insurance (or in the case of a
master or single interest policy, the incremental cost (including any deductible
relating to such insurance) of such insurance relating to the specific Mortgaged
Property), shall be a Servicing Advance and shall be recoverable by the Master
Servicer pursuant to Section 3.05(a). If at any time a Mortgaged Property is
located in an area identified in the Flood Hazard Boundary Map or Flood
Insurance Rate Map issued by the Federal Emergency Management Agency as having
special flood hazards or it becomes located in such area by virtue of remapping
conducted by such agency (and flood insurance has been made available), the
Master Servicer (or in the case of a Specially Serviced Loan, the Special
Servicer) shall, if and to the extent that the Mortgage Loan or Companion Loan
requires the Mortgagor or permits the mortgagee to require the Mortgagor to do
so, use reasonable efforts to cause the related Mortgagor to maintain a flood
insurance policy meeting the requirements of the current guideline of the
Federal Insurance Administration in the maximum amount of insurance coverage
available under the National Flood Insurance Act of 1968, the Flood Disaster
Protection Act of 1973 or the National Flood Insurance Reform Act of 1994, as
amended, unless otherwise specified by the related Mortgage Loan or Companion
Loan. If (i) the Mortgagor is required by the terms of the Mortgage Loan or
Companion Loan to maintain such insurance (or becomes obligated by virtue of the
related Mortgaged Property becoming located in such area by virtue of such
remapping) or (ii) the terms of the Mortgage Loan or Loan Group permit the
mortgagee to require the Mortgagor to obtain such insurance, the Master Servicer
(or in the case of a Specially Serviced Loan, the Special Servicer), shall
promptly notify the Mortgagor of its obligation to obtain such insurance. If the
Mortgagor fails to obtain such flood insurance within 120 days of such
notification, the Master Servicer (or in the case of a Specially Serviced Loan,
the Special Servicer) shall obtain such insurance, the cost of which shall be a
Servicing Advance and shall be recoverable by the Master Servicer or Special
Servicer pursuant to Section 3.05(a); provided that the Master Servicer or
Special Servicer shall not be required to incur any such cost if such Advance
would constitute a Nonrecoverable Servicing Advance. Subject to Section 3.17(a),
the Special Servicer shall also use reasonable efforts to cause to be maintained
for each REO Property (to the extent available at commercially reasonable terms)
no less insurance coverage than was previously required of the Mortgagor under
the related Mortgage or as is consistent with the Servicing Standard. All such
insurance policies shall contain a "standard" mortgagee clause, with loss
payable to the Master Servicer (in the case of Mortgaged Properties) or the
Special Servicer (in the case of REO Properties) on behalf of the Trustee, and
shall be issued by an insurer authorized under applicable law to issue such
insurance. Any amounts collected by the Master Servicer or the Special Servicer
under any such policies (other than amounts to be applied to the restoration or
repair of the related Mortgaged Property or REO Property or amounts to be
released to the related Mortgagor, in each case in accordance with applicable
law, the terms of the related Mortgage Loan or Companion Loan documents and the
Servicing Standard) shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.05(a), in the case of amounts received in
respect of a Mortgage Loan or Companion Loan, or in the REO Account, subject to
withdrawal pursuant to Section 3.16(c), in the case of amounts received in
respect of an REO Property. Any cost incurred by the Master Servicer or the
Special Servicer in maintaining any such insurance shall not, for purposes
hereof, including, without limitation, calculating monthly distributions to
Certificateholders, be added to the outstanding principal balance of the related
Mortgage Loan or Companion Loan, notwithstanding that the terms of such Mortgage
Loan or Companion Loan so

                                       93
<PAGE>

permit, but shall be recoverable by the Master Servicer as a Servicing Advance
pursuant to Section 3.05(a).

                  (b) (i) If the Master Servicer or the Special Servicer obtains
and maintains a blanket policy insuring against hazard losses on all of the
Mortgaged Properties and/or REO Properties for which it is responsible to cause
the maintenance of insurance hereunder, then, to the extent such policy provides
protection equivalent to the individual policies otherwise required, the Master
Servicer or the Special Servicer, as the case may be, shall conclusively be
deemed to have satisfied its obligation to cause hazard insurance to be
maintained on such Mortgaged Properties and/or REO Properties. Such policy may
contain a deductible clause (not in excess of a customary amount), in which case
the Master Servicer or the Special Servicer, as appropriate, shall, if there
shall not have been maintained on a Mortgaged Property or an REO Property a
hazard insurance policy complying with the requirements of Section 3.07(a), and
there shall have been one or more losses which would have been covered by such
policy, promptly deposit into the Collection Account (or into the Servicing
Account if insurance proceeds are to be applied to the repair or restoration of
the applicable Mortgaged Property or disbursed to the related Mortgagor) from
its own funds the amount not otherwise payable under the blanket policy because
of such deductible clause to the extent that any such deductible exceeds the
deductible limitation that pertained to the related Mortgage Loan, or, in the
absence of any such deductible limitation, the deductible limitation which is
consistent with the Servicing Standard. The Master Servicer and the Special
Servicer each agrees to prepare and present, on behalf of itself, the Trustee
and Certificateholders, claims under any such blanket policy maintained by it in
a timely fashion in accordance with the terms of such policy.

                          (ii) If the Master Servicer or the Special Servicer,
             as applicable, causes any Mortgaged Property or REO Property to be
             covered by a master force placed insurance policy, which provides
             protection equivalent to the individual policies otherwise
             required, the Master Servicer or Special Servicer shall
             conclusively be deemed to have satisfied its respective obligations
             to cause hazard insurance to be maintained on such Mortgaged
             Properties and/or REO Properties. Such policy may contain a
             deductible clause, in which case the Master Servicer or the Special
             Servicer, as applicable, shall in the event that (x) there shall
             not have been maintained on the related Mortgaged Property or REO
             Property a policy otherwise complying with the provisions of
             Section 3.07(a), and (y) there shall have been one or more losses
             which would have been covered by such a policy had it been
             maintained, immediately deposit into the Collection Account (or
             into the Servicing Account if insurance proceeds are to be applied
             to the repair or restoration of the applicable Mortgaged Property
             or disbursed to the related Mortgagor) from its own funds the
             amount not otherwise payable under such policy because of such
             deductible to the extent that any such deductible exceeds the
             deductible limitation that pertained to the related Mortgage Loan,
             or, in the absence of any such deductible limitation, the
             deductible limitation which is consistent with the Servicing
             Standard. The Master Servicer and the Special Servicer each agrees
             to prepare and present, on behalf of itself, the Trustee and the
             Certificateholders, claims under any such master force placed
             insurance policy maintained by it in a timely fashion in accordance
             with the terms of such policy.

                                       94
<PAGE>

                  (c) Each of the Master Servicer and the Special Servicer shall
obtain and maintain at its own expense and keep in full force and effect
throughout the term of this Agreement a blanket fidelity bond and an errors and
omissions insurance policy covering its officers and employees and other persons
acting on behalf of it in connection with its activities under this Agreement
and naming the Trustee as an additional insured. The amount of coverage shall be
at least equal to the coverage that would be required by FNMA or FHLMC,
whichever is greater, with respect to the Master Servicer or Special Servicer,
as the case may be, if the Master Servicer or Special Servicer, as the case may
be, were servicing and administering the Mortgage Loans, Companion Loans and/or
REO Properties for which it is responsible hereunder for FNMA or FHLMC. Coverage
of the Master Servicer or the Special Servicer under a policy or bond obtained
by an Affiliate of such Person and providing the coverage required by this
Section 3.07(c) shall satisfy the requirements of this Section 3.07(c).

                  (d) All insurance coverage required to be maintained by the
Master Servicer or Special Servicer, as applicable, under this Section 3.07
shall be obtained from Qualified Insurers having a claims paying ability rating
(or the obligations of which are guaranteed or backed by a company having such
claims paying ability rating or insurance financial strength rating, as
applicable) of not less than (x) A2 by Moody's and (y) if rated by Fitch, "A" by
Fitch (or, if not rated by Fitch, rated A-IX or better by A.M. Best); provided,
however, that the requirements of clauses (x) and (y) shall not be applicable
with respect to Moody's or Fitch, as applicable, if the related Rating Agency
shall have confirmed in writing that an insurance company with a lower claims
paying ability rating shall not result, in and of itself, in a downgrade,
qualification or withdrawal of the then current ratings by such Rating Agency of
any class of Certificates.

                  SECTION 3.08  Enforcement of Due-On-Sale Clauses; Assumption
                                Agreements; Subordinate Financing; Defeasance.

                  (a) As to each Mortgage Loan or Companion Loan which contains
a provision in the nature of a "due-on-sale" clause, which by its terms:

                          (i) provides that such Mortgage Loan or Companion Loan
             shall (or may at the mortgagee's option) become due and payable
             upon the sale or other transfer of an interest in the related
             Mortgaged Property; or

                          (ii) provides that such Mortgage Loan or Companion
             Loan may not be assumed without the consent of the mortgagee in
             connection with any such sale or other transfer,

then, for so long as such Mortgage Loan or Companion Loan is included in the
Trust Fund, the Special Servicer, on behalf of the Trustee as the mortgagee of
record, shall exercise (or, subject to Section 3.20(a)(iv), waive its right to
exercise) any right it may have with respect to such Mortgage Loan or Companion
Loan (x) to accelerate the payments thereon, or (y) to withhold its consent to
any such sale or other transfer, in a manner consistent with the Servicing
Standard. In the event that the Special Servicer intends or is required, in
accordance with the preceding sentence, the Mortgage Loan or Companion Loan
documents or applicable law, to permit the transfer of any Mortgaged Property,
the Special Servicer, if consistent with the Servicing

                                       95
<PAGE>

Standard, may enter into an assumption and modification agreement with the
Person to whom the related Mortgaged Property has been or is intended to be
conveyed or may enter into a substitution of liability agreement, pursuant to
which the original Mortgagor and any original guarantors are released from
liability, and the transferee and any new guarantors are substituted therefor
and become liable under the Mortgage Note and any related guaranties and, in
connection therewith, may require from the related Mortgagor a reasonable and
customary fee for the additional services performed by it, together with
reimbursement for any related costs and expenses incurred by it (but only to the
extent that charging such fee and entering into such assumption and modification
agreement will not be a significant modification of the Mortgage Loan or
Companion Loan for purposes of the REMIC Provisions). The Special Servicer shall
promptly notify the Trustee of any such agreement and forward the original
thereof to the Trustee for inclusion in the related Mortgage File. Subject to
Section 3.20(a), if the Special Servicer intends or is required to permit the
transfer of any Mortgaged Property and enter into an assumption agreement or a
substitution of liability agreement, as the case may be, in accordance with the
foregoing, the Special Servicer shall submit to (A) Fitch, in the case of any
Mortgage Loan or Loan Group that has, or any Mortgage Loan or Loan Group that is
part of a Related Borrower Group that has, one of the then-ten highest
outstanding principal balances in the Mortgage Pool; and (B) Moody's, in the
case of any Mortgage Loan or Loan Group that has an outstanding principal
balance in excess of the lesser of (1) $20,000,000 or (2) 2% of the then
outstanding principal balance of the Mortgage Pool a copy of such documentation
and any information with respect to such action as the Special Servicer deems
appropriate or as such Rating Agency may reasonably request, and shall obtain
Rating Agency Confirmation from Fitch (in the case of any Mortgage Loan or Loan
Group described in clause (A) above) and Moody's (in the case of any Mortgage
Loan or Loan Group described in clause (B) above) prior to executing such
assumption agreement or substitution of liability agreement; provided, however,
if the Special Servicer shall not have received such Rating Agency Confirmation
from Fitch within five (5) Business Days of such Rating Agency's receipt of a
copy of such documentation and such information, such Rating Agency Confirmation
shall be deemed to have been delivered to the Special Servicer by Fitch.

                  (b) As to each Mortgage Loan or Companion Loan which contains
a provision in the nature of a "due-on-encumbrance" clause, which by its terms:

                          (i) provides that such Mortgage Loan or Companion Loan
             shall (or may at the mortgagee's option) become due and payable
             upon the creation of any additional lien or other encumbrance on
             the related Mortgaged Property; or

                          (ii) requires the consent of the mortgagee to the
             creation of any such additional lien or other encumbrance on the
             related Mortgaged Property,

then, for so long as such Mortgage Loan or Companion Loan is included in the
Trust Fund, the Special Servicer, on behalf of the Trustee as the mortgagee of
record, shall exercise (or, subject to Section 3.20(a)(iv), waive its right to
exercise) any right it may have with respect to such Mortgage Loan or Companion
Loan (x) to accelerate the payments thereon, or (y) to withhold its consent to
the creation of any such additional lien or other encumbrance, in a manner
consistent with the Servicing Standard; provided, however that the Special
Servicer, shall not waive its right to exercise any such right when such right
arises as a result of the imposition of a lien

                                       96
<PAGE>

against a Mortgaged Property which lien secures additional indebtedness or a
mechanic's or similar lien not permitted under the related Mortgage Loan or
Companion Loan documents unless, the Special Servicer shall submit to (A) Fitch
(but only in the case of any Mortgage Loan or Loan Group that has, or any
Mortgage Loan or Loan Group that is part of a Related Borrower Group that has,
one of the then-ten highest outstanding principal balances in the Mortgage
Pool), and (B) Moody's (in the case of any Mortgage Loan or Loan Group that has
an outstanding principal balance in excess of the lesser of (1) $20,000,000 or
(2) 2% of the then outstanding principal balance of the Mortgage Pool) a copy of
the documentation under which any such lien would arise together with such other
information with respect to such proposed waiver as the Special Servicer deems
appropriate or as such Rating Agency may reasonably request, and shall obtain
Rating Agency Confirmation with respect to such proposed waiver; provided,
however, if the Special Servicer shall not have received such Rating Agency
Confirmation from Fitch within five (5) Business Days of such Rating Agency's
receipt of a copy of such documentation and such information, such Rating Agency
Confirmation shall be deemed to have been delivered to the Special Servicer by
Fitch.

                  (c) With respect to any Mortgage Loan or Loan Group which
permits release of Mortgaged Properties through a Defeasance Option, the Master
Servicer shall, to the extent consistent with and permitted by the applicable
Mortgage Loan documents, permit (or, if the terms of such Mortgage Loan or Loan
Group permit the lender to require defeasance, the Master Servicer shall
require) the exercise of such Defeasance Option on any Due Date occurring more
than two years after the Startup Day (the "Release Date") subject to the
following conditions:

                          (i) No event of default exists under the related
             Mortgage Note;

                          (ii) The Mortgagor pays on such Release Date (A) all
             interest accrued and unpaid on the Principal Balance of the
             Mortgage Note to and including the Release Date; (B) all other
             sums, excluding scheduled interest or principal payments due under
             the Mortgage Note and (C) any costs and expenses incurred in
             connection with such release;

                          (iii) The Mortgagor has delivered Defeasance
             Collateral providing payments on or prior to all successive
             scheduled payment dates from the Release Date to the related
             Maturity Date, and in an amount equal to or greater than the
             scheduled payments due on such dates under the Mortgage Loan or
             Loan Group;

                          (iv) The Mortgagor shall have delivered a security
             agreement granting the Trust Fund a first priority security
             interest in the Defeasance Collateral;

                          (v) The Master Servicer shall have received an Opinion
             of Counsel from the related Mortgagor (which shall be an expense of
             the related Mortgagor) to the effect that the Trust Fund has a
             first priority security interest in the Defeasance Collateral and
             that the assignment thereof is valid and enforceable;

                          (vi) The Master Servicer shall have obtained at the
             related Mortgagor's expense a certificate from an Independent
             certified public accountant certifying that the Defeasance
             Collateral complies with the requirements of the related Mortgage
             Note;

                                       97
<PAGE>

                          (vii) The Master Servicer shall have obtained an
             Opinion of Counsel from the related Mortgagor to the effect that
             such release will not cause any of REMIC I, REMIC II or REMIC III
             to fail to qualify as a REMIC at any time that any Certificates are
             outstanding or cause a tax to be imposed on the Trust Fund under
             the REMIC Provisions;

                          (viii) The Borrower shall have provided evidence to
             the Master Servicer demonstrating that the lien of the related
             Mortgage is being released to facilitate the disposition of the
             Mortgaged Property or another customary commercial transaction, and
             not as part of an arrangement to collateralize the Certificates
             issued by the related REMIC with obligations that are not real
             estate mortgages;

                          (ix) If required by the terms of such Mortgage Loan or
             Loan Group, the Master Servicer shall have received Rating Agency
             Confirmation from each of Fitch and Moody's with respect to the
             exercise of such Defeasance Option; and

                          (x) if the Defeasance Option is being exercised to
             release less than all of the Mortgaged Properties securing either a
             Cross-Collateralized Mortgage Loan or a Mortgage Loan, or Loan
             Group secured by multiple Mortgaged Properties, the Borrower shall
             have provided evidence satisfactory to both the Master Servicer and
             the Special Servicer that demonstrates compliance with any debt
             service coverage ratio, loan-to-value ratio or other financial
             tests or conditions specified in the applicable Mortgage Loan or
             Loan Group in connection with the exercise of such Defeasance
             Option.

                  (d) Nothing in this Section 3.08 shall constitute a waiver of
the Trustee's right, as the mortgagee of record, to receive notice of any
assumption of a Mortgage Loan or Loan Group, any sale or other transfer of the
related Mortgaged Property or the creation of any additional lien or other
encumbrance with respect to such Mortgaged Property.

                  (e) Except as otherwise permitted by Section 3.20, neither the
Master Servicer nor the Special Servicer shall agree to modify, waive or amend
any term of any Mortgage Loan or Loan Group in connection with the taking of, or
the failure to take, any action pursuant to this Section 3.08.

                  (f) In the event that the Master Servicer receives a request
from any Mortgagor for consent to (i) the transfer of a Mortgaged Property or
assumption of a Mortgage Loan or Loan Group pursuant to Section 3.08(a) or (ii)
the creation of an additional lien or encumbrance on a Mortgaged Property
pursuant to Section 3.08(b), the Master Servicer shall notify the Special
Servicer of such request and furnish to the Special Servicer any applicable
transfer, assumption, encumbrance or related documentation which the Master
Servicer has received in connection with such request.

                  SECTION 3.09  Realization Upon Defaulted Mortgage Loans.

                  (a) The Master Servicer shall notify the Special Servicer of
the occurrence of a Servicing Transfer Event in respect of any Mortgage Loan or
Loan Group. The Special Servicer shall monitor such Specially Serviced Mortgage
Loan, evaluate whether the causes of the default can be corrected over a
reasonable period without significant impairment of the value

                                       98
<PAGE>

of the related Mortgaged Property, initiate corrective action in cooperation
with the Mortgagor if, in the Special Servicer's judgment, cure is likely, and
take such other actions (including without limitation, negotiating and accepting
a discounted payoff of a Mortgage Loan or Companion Loan) as are consistent with
the Servicing Standard. If, in the Special Servicer's judgment, such corrective
action has been unsuccessful, no satisfactory arrangement can be made for
collection of delinquent payments, and the Defaulted Mortgage Loan has not been
released from the Trust Fund pursuant to any provision hereof, then the Special
Servicer shall, subject to subsections (b) through (d) of this Section 3.09,
exercise reasonable efforts, consistent with the Servicing Standard, to
foreclose upon or otherwise comparably convert (which may include an REO
Acquisition) the ownership of property securing such Mortgage Loan or Loan
Group. The foregoing is subject to the provision that, in any case in which a
Mortgaged Property shall have suffered damage from an Uninsured Cause, the
Master Servicer and the Special Servicer shall have the right but not the
obligation to expend its own funds toward the restoration of such property if it
shall determine in its reasonable discretion (i) that such restoration will
increase the net proceeds of liquidation of such Mortgaged Property to
Certificateholders after reimbursement to itself for such expenses, and (ii)
that such expenses will be recoverable by the Master Servicer or Special
Servicer, as the case may be, out of the proceeds of liquidation of such
Mortgaged Property, as contemplated in Section 3.05(a). The Special Servicer
(or, subject to Section 3.19(c), the Master Servicer) shall advance all other
costs and expenses incurred by it in any such proceedings, subject to its being
entitled to reimbursement therefor as a Servicing Advance as provided in Section
3.05(a) and further subject to its being entitled to pay out of the related
Liquidation Proceeds any Liquidation Expenses incurred in respect of any
Mortgage Loan or Loan Group, which Liquidation Expenses were outstanding at the
time such proceeds are received. When applicable state law permits the Special
Servicer to select between judicial and non-judicial foreclosure in respect of
any Mortgaged Property, the Special Servicer shall make such selection in a
manner consistent with the Servicing Standard. Nothing contained in this Section
3.09 shall be construed so as to require the Special Servicer, on behalf of the
Trust Fund, to make a bid on any Mortgaged Property at a foreclosure sale or
similar proceeding that is in excess of the fair market value of such property,
as determined by the Special Servicer in its sole judgment taking into account
the factors described in Section 3.18(e) and the results of any Appraisal
obtained pursuant to this Agreement, all such bids to be made in a manner
consistent with the Servicing Standard. If and when the Master Servicer or the
Special Servicer deems it necessary and prudent for purposes of establishing the
fair market value of any Mortgaged Property securing a Defaulted Mortgage Loan,
whether for purposes of bidding at foreclosure or otherwise, the Master Servicer
or the Special Servicer, as the case may be, is authorized to have an Appraisal
performed with respect to such property (the cost of which Appraisal shall be
covered by, and reimbursable as, an Additional Trust Fund Expense).

                  (b) The Special Servicer shall not acquire any personal
property pursuant to this Section 3.09 (with the exception of cash or cash
equivalents pledged as collateral for a Mortgage Loan or Companion Loan) unless
either:

                          (i) such personal property is incident to real
             property (within the meaning of Section 856(e)(1) of the Code) so
             acquired by the Special Servicer; or

                          (ii) the Special Servicer shall have obtained an
             Opinion of Counsel (the cost of which may be withdrawn from the
             Collection Account pursuant to Section

                                       99
<PAGE>

             3.05(a)) to the effect that the holding of such personal property
             by the Trust Fund will not (subject to Section 10.01(f)) cause the
             imposition of a tax on the Trust Fund under the REMIC Provisions or
             cause any of REMIC I, REMIC II or REMIC III to fail to qualify as a
             REMIC at any time that any Certificate is outstanding.

                  (c) Notwithstanding the foregoing provisions of this Section
3.09, the Special Servicer shall not, on behalf of the Trustee, initiate
foreclosure proceedings, obtain title to a Mortgaged Property in lieu of
foreclosure or otherwise, have a receiver of rents appointed with respect to any
Mortgaged Property, or take any other action with respect to any Mortgaged
Property, if, as a result of any such action, the Trustee, on behalf of 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 CERCLA or any comparable law, unless
(as evidenced by an Officer's Certificate to such effect delivered to the
Trustee) the Special Servicer has previously received an Environmental
Assessment in respect of such Mortgaged Property prepared within the twelve
months preceding such determination by a Person who regularly conducts
Environmental Assessments and the Special Servicer, based solely (as to
environmental matters and related costs) on the information set forth in such
Environmental Assessment, determines that:

                          (i) the Mortgaged Property is in compliance with
             applicable environmental laws and regulations or, if not, that
             acquiring such Mortgaged Property and taking such actions as are
             necessary to bring the Mortgaged Property in compliance therewith
             is reasonably likely to produce a greater recovery to
             Certificateholders on a present value basis than not acquiring such
             Mortgaged Property and not taking such actions; and

                          (ii) there are no circumstances or conditions present
             at the Mortgaged Property relating to the use, management or
             disposal of Hazardous Materials for which investigations, testing,
             monitoring, containment, clean-up or remediation could be required
             under any applicable environmental laws and regulations or, if such
             circumstances or conditions are present for which any such action
             could be required, that acquiring such Mortgaged Property and
             taking such actions with respect to such Mortgaged Property is
             reasonably likely to produce a greater recovery to
             Certificateholders on a present value basis than not acquiring such
             Mortgaged Property and not taking such actions.

The cost of any such Environmental Assessment, as well as the cost of any
remedial, corrective or other further action contemplated by clause (i) and/or
clause (ii) of the preceding sentence, may be withdrawn from the Collection
Account by the Master Servicer at the direction of the Special Servicer as an
expense of the Trust Fund pursuant to Section 3.05(a); and if any such
Environmental Assessment so warrants, the Special Servicer shall, at the expense
of the Trust Fund, perform such additional environmental testing as are
consistent with the Servicing Standard to determine whether the conditions
described in clauses (i) and (ii) of the preceding sentence have been satisfied.

                  (d) If the environmental testing contemplated by subsection
(c) above establishes that either of the conditions set forth in clauses (i) and
(ii) of the first sentence thereof

                                      100
<PAGE>

has not been satisfied with respect to any Mortgaged Property securing a
Defaulted Mortgage Loan, then the Special Servicer shall take such action as it
deems to be in the best economic interest of the Trust Fund (other than
proceeding to acquire title to the Mortgaged Property); and is hereby authorized
at such time as it deems appropriate to release all or a portion of such
Mortgaged Property from the lien of the related Mortgage.

                  (e) The Special Servicer shall provide written reports monthly
to the Master Servicer (who shall forward such reports to the Trustee, who shall
forward such reports to the Certificateholders) regarding any actions taken by
the Special Servicer with respect to any Mortgaged Property securing a Defaulted
Mortgage Loan as to which the environmental testing contemplated in subsection
(c) above has revealed that either of the conditions set forth in clauses (i)
and (ii) of the first sentence thereof has not been satisfied, in each case
until the earliest to occur of satisfaction of both such conditions, removal of
the related Mortgage Loan or Loan Group from the Trust Fund and release of the
lien of the related Mortgage on such Mortgaged Property.

                  (f) The Special Servicer shall report to the Internal Revenue
Service and the related Mortgagor, in the manner required by applicable law, the
information required to be reported regarding any Mortgaged Property which is
abandoned or foreclosed, information returns with respect to the receipt of
mortgage interests received in a trade or business and the information returns
relating to cancellation of indebtedness income with respect to any Mortgaged
Property required by Sections 6050J, 6050H and 6050P, respectively, of the Code.
Such reports shall be in form and substance sufficient to meet the reporting
requirements imposed by Sections 6050J, 6050H and 6050P of the Code. The Special
Servicer shall deliver a copy of any such report upon request to the Trustee.

                  (g) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, the advisability of the maintenance of
an action to obtain a deficiency judgment if the state in which the Mortgaged
Property is located and the terms of the Mortgage Loan or Companion Loan permit
such an action.

                  (h) The Special Servicer shall maintain accurate records of
each Final Recovery Determination in respect of a Defaulted Mortgage Loan or REO
Property and the basis thereof. Each Final Recovery Determination shall be
evidenced by an Officer's Certificate delivered to the Trustee no later than the
10th Business Day following such Final Recovery Determination.

                  SECTION 3.10  Trustee to Cooperate; Release of Mortgage Files.

                  (a) Upon the payment in full of any Mortgage Loan or Loan
Group, or the receipt by the Master Servicer or the Special Servicer of a
notification that payment in full shall be escrowed in a manner customary for
such purposes, the Master Servicer or the Special Servicer, as the case may be,
will immediately notify the Trustee and request delivery of the related Mortgage
File. Any such notice and request shall be in the form of a Request for Release
signed by a Servicing Officer and 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 3.04(a)
have been or will be so deposited. Within seven

                                      101
<PAGE>

Business Days (or within such shorter period as release can reasonably be
accomplished if the Master Servicer or the Special Servicer notifies the Trustee
of an exigency) of receipt of such notice and request, the Trustee shall
release, or cause any related Custodian to release, the related Mortgage File to
the Master Servicer or the Special Servicer, whichever requested it. No expenses
incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account.

                  (b) From time to time as is appropriate for servicing or
foreclosure of any Mortgage Loan or Loan Group, the Master Servicer or the
Special Servicer may deliver to the Trustee a Request for Release signed by a
Servicing Officer thereof. Upon receipt of the foregoing, the Trustee shall
deliver or cause the related Custodian to deliver, the Mortgage File or any
document therein to the Master Servicer or the Special Servicer, as the case may
be. Upon return of such Mortgage File or such document to the Trustee or the
related Custodian, or the delivery to the Trustee of a certificate of a
Servicing Officer stating that such Mortgage Loan or Loan Group was liquidated
and that all amounts received or to be received in connection with such
liquidation which are required to be deposited into the Collection Account
pursuant to Section 3.04(a) have been or will be so deposited, or that such
Mortgage Loan or Loan Group has become an REO Property, the Request for Release
shall be released by the Trustee to the Master Servicer or the Special Servicer,
as applicable.

                  (c) Within three Business Days (or within such shorter period
as delivery can reasonably be accomplished if the Special Servicer notifies the
Trustee of an exigency) of receipt thereof, the Trustee shall execute and
deliver to the Special Servicer any court pleadings, requests for trustee's sale
or other documents 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. The Special
Servicer shall be responsible for the preparation of all such documents and
pleadings. When submitted to the Trustee for signature, such documents or
pleadings shall be accompanied by a certificate of a Servicing Officer
requesting that such pleadings or documents be executed by the Trustee and
certifying as to the reason such documents or pleadings are required and that
the execution and delivery thereof 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 3.11  Servicing Compensation; Nonrecoverable Servicing
                                Advances.

                  (a) As compensation for its activities hereunder, the Master
Servicer shall be entitled to receive the Servicing Fee with respect to each
Mortgage Loan and REO Loan and with respect to each Companion Loan, the
Companion Servicing Fee. As to each Mortgage Loan, Companion Loan and REO Loan,
the Servicing Fee and the Companion Servicing Fee shall accrue from time to time
at the Servicing Fee Rate and shall be computed on the same basis and the same
principal amount respecting which any related interest payment due on such
Mortgage Loan or Companion Loan or deemed to be due on such REO Loan is
computed. The Servicing Fee and the Companion Servicing Fee with respect to any
Mortgage Loan or Companion Loan or REO Loan shall cease to accrue if a
Liquidation Event occurs in respect thereof. The Servicing Fee and the Companion
Servicing Fee shall be payable monthly, on a

                                      102
<PAGE>

loan-by-loan basis, from payments of interest on each Mortgage Loan or Companion
Loan, REO Revenues allocable as interest on each REO Loan and the interest
portion of Delinquency Advances on each Mortgage Loan or Companion Loan and REO
Loan. The Master Servicer shall be entitled to recover unpaid Servicing Fees in
respect of any Mortgage Loan or Companion Loan or REO Loan out of that portion
of related Insurance Proceeds or Liquidation Proceeds allocable as recoveries of
interest, to the extent permitted by Section 3.05(a). The right to receive the
Servicing Fee and the Companion 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.

                  (b) Additional servicing compensation in the form of
assumption fees, modification fees, earnout fees, charges for beneficiary
statements or demands, amounts collected for checks returned for insufficient
funds and any similar or ancillary fees (excluding any other amounts relating to
Prepayment Premiums), in each case to the extent actually paid by a Mortgagor
with respect to a Mortgage Loan (or, if a Loan Group is involved, such Loan
Group) that is not a Specially Serviced Mortgage Loan is not required to be
deposited in the Collection Account and, to the extent not required to be paid
to the Special Servicer pursuant to Section 3.11(d), may be retained by the
Master Servicer. The Master Servicer shall also be entitled to additional
servicing compensation in the form of (i) any Prepayment Interest Excesses,
Balloon Payment Interest Excesses, and further to the extent received on
Mortgage Loans (or, if a Loan Group is involved, such Loan Group) other than
Specially Serviced Mortgage Loans, any Penalty Charges not allocable to pay
Advance Interest collected on the Mortgage Loans and Companion Loans; (ii)
interest or other income earned on deposits in the Investment Accounts (other
than the REO Account), in accordance with Section 3.06(b) (but only to the
extent of the Net Investment Earnings, if any, with respect to each such
Investment Account for each Collection Period), and (iii) to the extent not
required to be paid to any Mortgagor under applicable law or under the related
Mortgage, any interest or other income earned on deposits in the Servicing
Accounts and Reserve Accounts maintained thereby. The Master Servicer shall be
required to pay out of its own funds all overhead and general and administrative
expenses incurred by it in connection with its servicing activities hereunder
(including, without limitation, payment of any amounts due and owing to any of
Sub-Servicers retained by it and the premiums for any blanket policy insuring
against hazard losses pursuant to Section 3.07(b)), if and to the extent such
expenses are not payable directly out of the Collection Account, and the Master
Servicer shall not be entitled to reimbursement therefor except as expressly
provided in this Agreement.

                  (c) As compensation for its activities hereunder, the Special
Servicer shall be entitled to receive the Special Servicing Fee with respect to
each Specially Serviced Mortgage Loan and each REO Loan. As to each Specially
Serviced Mortgage Loan and each REO Loan, the Special Servicing Fee shall accrue
from time to time at the Special Servicing Fee Rate on the same basis and the
same principal amount respecting which any related interest payment due on such
Specially Serviced Mortgage Loan or deemed to be due on such REO Loan is
computed. The Special Servicing Fee with respect to each such Specially Serviced
Mortgage Loan and each REO Loan shall cease to accrue as of the date a
Liquidation Event occurs in respect thereof. As to each such Specially Serviced
Mortgage Loan and each REO Loan, earned but unpaid Special Servicing Fees shall
be payable monthly out of general collections on the Mortgage Loans and

                                      103
<PAGE>

Companion Loans and any REO Properties on deposit in the Collection Account
pursuant to Section 3.05(a).

                  As further compensation for its activities hereunder, the
Special Servicer shall be entitled to receive the Workout Fee with respect to
each Corrected Mortgage Loan. As to each Corrected Mortgage Loan, the Workout
Fee shall be payable from, and shall be calculated by application of the Workout
Fee Rate to, each collection of interest and principal received on such Mortgage
Loan or Loan Group for so long as it remains a Corrected Mortgage Loan. The
Workout Fee with respect to any Corrected Mortgage Loan will cease to be payable
if a Servicing Transfer Event occurs with respect thereto or if the related
Mortgaged Property becomes an REO Property; provided that a new Workout Fee will
become payable if and when such Mortgage Loan or Loan Group again becomes a
Corrected Mortgage Loan. If the Special Servicer is terminated other than for
cause or resigns in accordance with Section 6.04, it shall retain the right to
receive any and all Workout Fees payable in respect of Mortgage Loans or
Companion Loans that became Corrected Mortgage Loans during the period that it
acted as Special Servicer and were still such at the time of such termination or
resignation (and the successor Special Servicer shall not be entitled to any
portion of such Workout Fees), in each case until the Workout Fee for any such
loan ceases to be payable in accordance with the preceding sentence.

                  As further compensation for its activities hereunder, the
Special Servicer shall also be entitled to receive a Liquidation Fee with
respect to each Specially Serviced Mortgage Loan or REO Property as to which it
receives any full or discounted payoff or any Liquidation Proceeds (other than
in connection with the purchase of any such Specially Serviced Mortgage Loan or
REO Property by the Special Servicer, the related Class S Certificateholder or
the Majority Certificateholder of the Controlling Class pursuant to Section 3.18
or by the Master Servicer or the Depositor pursuant to Section 3.18 or by the
Master Servicer or the Depositor pursuant to Section 9.01). As to each such
Specially Serviced Mortgage Loan or REO Property, the Liquidation Fee shall be
payable from, and shall be calculated by application of the Liquidation Fee Rate
to, such full or discounted payoff and/or such Liquidation Proceeds. No
Liquidation Fee will be payable with respect to any Specially Serviced Mortgage
Loan solely by virtue of such Mortgage Loan or Loan Group becoming a Corrected
Mortgage Loan. Notwithstanding anything herein to the contrary, no Liquidation
Fee will be payable from, or based upon the receipt of, Liquidation Proceeds
collected as a result of any purchase of a Specially Serviced Mortgage Loan or
REO Property described in the parenthetical to the first sentence of this
paragraph; provided, however, that if any such Liquidation Proceeds are received
with respect to any Corrected Mortgaged Loan, and the Special Servicer is
properly entitled to a Workout Fee therefrom, such Workout Fee will be payable
based on and from the portion of such Liquidation Proceeds that constitute
principal and/or interest.

                  Notwithstanding anything to the contrary herein, a Liquidation
Fee and a Workout Fee relating to the same Mortgage Loan or Loan Group shall not
be paid from the same proceeds on or with respect to such Mortgage Loan or Loan
Group.

                  Subject to the Special Servicer's right to employ
Sub-Servicers, the Special Servicer's right to receive the Special Servicing
Fee, the Workout Fee and/or the Liquidation Fee

                                      104
<PAGE>

may not be transferred in whole or in part except in connection with the
transfer of all of the Special Servicer's responsibilities and obligations under
this Agreement.

                  (d) Additional servicing compensation in the form of (i) all
assumption fees and modification fees received on or with respect to Specially
Serviced Mortgage Loans and (ii) fifty percent (50%) of all assumption fees and
earnout fees received on or with respect to Mortgage Loans or Loan Groups that
are not Specially Serviced Mortgage Loans shall be promptly paid by the Master
Servicer to the Special Servicer and shall not be required to be deposited in
the Collection Account pursuant to Section 3.04(a). Additional servicing
compensation in the form of assumption fees, earnout fees and modification fees
that the Master Servicer is entitled to and that are collected by the Special
Servicer, shall be paid promptly to the Master Servicer by the Special Servicer.
The Special Servicer shall also be entitled to additional servicing compensation
in the form of: (i) to the extent not required to be paid to any Mortgagor under
applicable law, any interest or other income earned on deposits in the REO
Account, any Servicing Accounts and any Reserve Accounts maintained thereby; and
(ii) to the extent not required to be paid to the Master Servicer as additional
servicing compensation pursuant to Section 3.11(b), any Penalty Charges (to the
extent not allocable to pay Advance Interest) collected on the Specially
Serviced Mortgage Loans and REO Loans. The Special Servicer shall be required to
pay out of its own funds all overhead and general and administrative expenses
incurred by it in connection with its servicing activities hereunder (including,
without limitation, payment of any amounts due and owing to any Sub-Servicers
retained by it and the premiums for any blanket policy obtained by it insuring
against hazard losses pursuant to Section 3.07(b)), if and to the extent such
expenses are not payable directly out of the Collection Account or the REO
Account, and the Special Servicer shall not be entitled to reimbursement except
as expressly provided in this Agreement.

                  (e) If the Master Servicer or Special Servicer is required
under this Agreement to make a Servicing Advance, but neither does so within 15
days after such Advance is required to be made, the Trustee shall, to the extent
a Responsible Officer of the Trustee has actual knowledge of such failure by the
Master Servicer or the Special Servicer to make such Advance (subject to Section
3.11(h) below), make such Advance. If the Trustee fails to make a Servicing
Advance required to be made by it, the Fiscal Agent shall make such advance
(subject to Section 3.11(h) below) within one (1) Business Day of such failure
by the Trustee. The making of such Advance by the Fiscal Agent shall cure the
failure by the Trustee to make such Advance.

                  (f) The Master Servicer, the Special Servicer, the Trustee and
the Fiscal Agent shall each be entitled to receive interest at the Reimbursement
Rate in effect from time to time, accrued on the amount of each Servicing
Advance made thereby for so long as such Servicing Advance is outstanding,
payable, first, out of Penalty Charges received on the Mortgage Loan or Loan
Group or REO Loan as to which such Servicing Advance was made and, then, once
such Servicing Advance has been reimbursed pursuant to Section 3.05, out of
general collections on the Mortgage Loans, Companion Loans and REO Properties.

                  (g) [Reserved]

                                      105
<PAGE>

                  (h) On each Master Servicer Remittance Date, the Master
Servicer shall pay from the related Servicing Fee, each Broker Strip Amount by
wire transfer in immediately available funds to an account designated by the
Strip Holder.

                  (i) Notwithstanding anything to the contrary set forth herein,
none of the Master Servicer, the Special Servicer, the Trustee or the Fiscal
Agent shall be required to make any Servicing Advance that it determines in its
reasonable, good faith judgment would constitute a Nonrecoverable Servicing
Advance; provided, however, that the Special Servicer may make an Emergency
Advance notwithstanding that, at the time such Advance is made, the Special
Servicer may not have adequate information available in order to make a
determination whether or not such advance would, if made, be a Nonrecoverable
Servicing Advance. In addition, Nonrecoverable Servicing Advances (including any
Emergency Advances made pursuant to the proviso of the preceding sentence which
are ultimately determined to be Nonrecoverable Servicing Advances) shall be
reimbursable pursuant to Section 3.05 out of general collections on the Mortgage
Loans, Companion Loans and REO Properties on deposit in the Collection Account.
The determination by the Master Servicer, the Special Servicer or, if
applicable, the Trustee or the Fiscal Agent, that it has made a Nonrecoverable
Servicing Advance or that any proposed Servicing Advance, if made, would
constitute a Nonrecoverable Servicing Advance, shall be evidenced by an
Officer's Certificate delivered promptly to the Trustee (or, if applicable,
retained thereby) and the Depositor, setting forth the basis for such
determination, together with (if such determination is prior to the liquidation
of the related Mortgage Loan or Loan Group or REO Property) a copy of an
Appraisal of the related Mortgaged Property or REO Property, as the case may be,
if an Appraisal shall have been performed within the twelve months preceding
such determination, and further accompanied by any other information, including,
without limitation, engineers' reports, environmental surveys, inspection
reports, rent rolls, income and expense statements or similar reports, that the
Master Servicer or the Special Servicer may have obtained and that supports such
determination. If such an Appraisal shall not have been required and performed
pursuant to the terms of this Agreement, the Master Servicer, the Special
Servicer, the Trustee or the Fiscal Agent, as the case may be, may, subject to
its reasonable and good faith determination that such Appraisal will demonstrate
the nonrecoverability of the related Advance, obtain an Appraisal for such
purpose at the expense of the Trust Fund. The Trustee or the Fiscal Agent shall
be entitled to rely on any determination of nonrecoverability that may have been
made by the Master Servicer or the Special Servicer with respect to a particular
Servicing Advance, and the Master Servicer shall be entitled to rely on any
determination of nonrecoverability that may have been made by the Special
Servicer with respect to a particular Servicing Advance.

                  SECTION 3.12  Inspections; Collection of Financial Statements.

                  (a) The Master Servicer shall perform (or cause to be
performed) a physical inspection of each Mortgaged Property (other than
Mortgaged Properties constituting collateral for Specially Serviced Mortgaged
Loans) at such times and in such manner as are consistent with the Servicing
Standard, but in any event at least once every two years or, if the related
Mortgage Loan or Loan Group has a current balance of greater than $2,000,000, at
least once every year. The Master Servicer shall prepare (or cause to be
prepared) a written report of each such inspection detailing the condition of
the Mortgaged Property and specifying the existence of (i) any vacancy in the
Mortgaged Property evident from such inspection that the Master Servicer

                                      106
<PAGE>

deems material, (ii) any sale, transfer or abandonment of the Mortgaged Property
evident from such inspection, (iii) any adverse change in the condition or value
of the Mortgaged Property evident from such inspection that the Master Servicer
deems material, or (iv) any waste committed on the Mortgaged Property evident
from such inspection. The Master Servicer, upon request, shall deliver to the
Trustee a copy of each such written report.

                  (b) The Special Servicer shall perform (or cause to be
performed) a physical inspection of each Mortgaged Property constituting
collateral for a Specially Serviced Mortgage Loan at such times and in such
manner as are consistent with the Servicing Standard. If any Mortgage Loan or
Companion Loan becomes a Specially Serviced Mortgage Loan, then as soon as
practicable (and in any event within 90 days thereafter) the Special Servicer
shall perform (or cause to be performed) a physical inspection of each Mortgaged
Property constituting collateral for such Mortgage Loan or Companion Loan. The
Special Servicer shall prepare (or cause to be prepared) a written report of
each such inspection detailing the condition of the Mortgaged Property and
specifying the existence of (i) any vacancy in the Mortgaged Property evident
from such inspection that the Special Servicer deems material, (ii) any sale,
transfer or abandonment of the Mortgaged Property evident from such inspection,
(iii) any adverse change in the condition or value of the Mortgaged Property
evident from such inspection that the Special Servicer deems material, or (iv)
any waste committed on the Mortgaged Property evident from such inspection. The
Special Servicer, upon request, shall deliver to the Trustee and the Master
Servicer a copy of each such written report.

                  (c) The Master Servicer (or, in the case of Specially Serviced
Mortgage Loans, the Special Servicer) shall make reasonable efforts to collect
promptly from each Mortgagor (other than a Mortgagor on a Credit Lease Loan)
quarterly and annual operating statements and rent rolls of the related
Mortgaged Property. In addition, the Special Servicer shall make reasonable
efforts to obtain quarterly and annual operating statements and rent rolls with
respect to each REO Property. The Master Servicer and Special Servicer, upon
request, shall each deliver copies of the collected items to the other such
party and the Trustee in each case within 10 days of its receipt of such
request.

                  SECTION 3.13  Annual Statement as to Compliance.

                  Each of the Master Servicer and the Special Servicer will
deliver to the Trustee, with a copy to the Depositor, on or before April 30th of
each year, beginning in 2001, an Officer's Certificate stating, as to the signer
thereof, that (i) a review of the activities of the Master Servicer or the
Special Servicer, as the case may be, during the preceding calendar year and of
its performance under this Agreement has been made under such officer's
supervision, (ii) to the best of such officer's knowledge, based on such review,
the Master Servicer or the Special Servicer, as the case may be, has fulfilled
in all material respects its obligations under this Agreement throughout such
year, or, if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof and (iii) the Master Servicer or the Special Servicer, as the case may
be, has received no notice regarding qualification, or challenging the status,
of the Trust Fund as a REMIC or of the Grantor Trust as a "grantor trust" under
the Grantor Trust Provisions from the Internal Revenue Service or any other
governmental agency or body or, if it has received any such notice,

                                      107
<PAGE>

specifying the details thereof. A copy of such Officer's Certificate may be
obtained by Certificateholders upon written request to the Trustee pursuant to
Section 8.12 hereof.

                  SECTION 3.14  Reports by Independent Public Accountants.

                  On or before April 30th of each year, beginning in 2001, the
Master Servicer at its expense shall cause a firm of independent public
accountants (which may also render other services to the Master Servicer) and
that is a member of the American Institute of Certified Public Accountants to
furnish a statement to the Trustee, and to the Depositor to the effect 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 mortgage loan servicing standards (to
the extent applicable to commercial and multifamily mortgage loans), identified
in the Uniform Single Attestation Program for Mortgage Bankers established by
the Mortgage Bankers Association of America, with respect to the servicing of
commercial and multifamily mortgage loans during the most recently completed
calendar 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 commercial and multifamily 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.

                  The Special Servicer will deliver an annual accountants'
report only if, and in such form as may be, requested by the Rating Agencies or
if the Special Servicer and the Master Servicer are not the same Person.

                  The Master Servicer and the Special Servicer, to the extent
applicable, will use reasonable efforts to cause the accountants referred to
above to cooperate with the Depositor in conforming any reports delivered
pursuant to this Section 3.14 to requirements imposed by the Commission on the
Depositor in connection with the Commission's issuance of a no-action letter
relating to the Depositor's reporting requirements in respect of the Trust Fund
pursuant to the Exchange Act.

                  SECTION 3.15  Access to Certain Information.

                  Each of the Master Servicer and the Special Servicer shall
provide or cause to be provided to the Trustee, and to the OTS, the FDIC, and
any other federal or state banking or insurance regulatory authority that may
exercise authority over any Certificateholder, access to any documentation
regarding the Mortgage Loans, Companion Loans, Loan Groups and the Trust Fund
within its control which may be required by this Agreement or by applicable law.
Such access shall be afforded without charge but only upon reasonable prior
written request and during normal business hours at the offices of the Master
Servicer or the Special Servicer, as the case may be, designated by it.

                                      108

                  SECTION 3.16  Title to REO Property; REO Account.

                  (a) If title to any REO Property is acquired, the deed or
certificate of sale shall be issued to the Trustee or its nominee on behalf of
the Certificateholders. The Special Servicer, on behalf of the Trust Fund, shall
attempt to sell any REO Property prior to the close of the third taxable year of
the Trust Fund following the taxable year in which the Trust Fund acquires
ownership of such REO Property for purposes of Section 860G(a)(8) of the Code,
unless the Special Servicer either (i) is granted an extension of time (an "REO
Extension") by the Internal Revenue Service to sell such REO Property or (ii)
obtains for the Trustee an Opinion of Counsel, addressed to the Trustee and the
Special Servicer, to the effect that the holding by the Trust Fund of such REO
Property subsequent to the close of such period will not (subject to Section
10.01(f)) result in the imposition of taxes on "prohibited transactions" of
REMIC I, REMIC II or REMIC III as defined in Section 860F of the Code or cause
REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC (for federal (or
any applicable state or local) income tax purposes) at any time that any
Certificates are outstanding. If the Special Servicer is granted the REO
Extension contemplated by clause (i) of the immediately preceding sentence or
obtains the Opinion of Counsel contemplated by clause (ii) of the immediately
preceding sentence, the Special Servicer shall sell such REO Property within
such longer liquidation period as is permitted by such REO Extension or such
Opinion of Counsel, as the case may be. Any expense incurred by the Special
Servicer in connection with its being granted the REO Extension contemplated by
clause (i) of the second preceding sentence or its obtaining the Opinion of
Counsel contemplated by clause (ii) of the second preceding sentence, shall be
an expense of the Trust Fund payable out of the Collection Account pursuant to
Section 3.05(a).

                  (b) The Special Servicer shall cause all funds collected and
received in connection with any REO Property to be held separate and apart from
its own funds and general assets. If any REO Acquisition shall occur, the
Special Servicer shall establish and maintain (or cause to be established and
maintained) one or more accounts (collectively, the "REO Account"), to be held
on behalf of the Trustee in trust for the benefit of the Certificateholders, for
the retention of revenues and other proceeds derived from each REO Property. The
REO Account shall be an Eligible Account and may consist of one account for some
or all of the REO Properties. The Special Servicer shall deposit, or cause to be
deposited, in the REO Account, within two Business Days of receipt, all REO
Revenues, Liquidation Proceeds (net of all Liquidation Expenses paid therefrom)
and Insurance Proceeds received in respect of an REO Property. The Special
Servicer is authorized to pay out of related Liquidation Proceeds any
Liquidation Expenses incurred in respect of an REO Property and outstanding at
the time such proceeds are received. Funds in the REO Account may be invested in
Permitted Investments in accordance with Section 3.06. The Special Servicer
shall be entitled to make withdrawals from the REO Account to pay itself, as
additional servicing compensation in accordance with Section 3.11(d), interest
and investment income earned in respect of amounts held in the REO Account as
provided in Section 3.06(b) (but only to the extent of the Net Investment
Earnings with respect to the REO Account for any Collection Period). The Special
Servicer shall give notice to the Trustee and the Master Servicer of the
location of any REO Account when first established and of the new location of
such REO Account prior to any change thereof.

                  (c) The Special Servicer shall cause all funds necessary for
the proper operation, management, maintenance, disposition and liquidation of
any REO Property to be

                                      109
<PAGE>

withdrawn from the REO Account, but only to the extent of amounts on deposit in
the REO Account relating to such REO Property. Within one Business Day following
the end of each Collection Period, the Special Servicer shall withdraw from the
REO Account and deposit into the Collection Account or deliver to the Master
Servicer (which shall deposit such amounts into the Collection Account) the
aggregate of all amounts received in respect of each REO Property during such
Collection Period, net of any withdrawals made out of such amounts pursuant to
Section 3.16 (b) or this Section 3.16(c); provided that the Special Servicer may
retain in the REO Account such portion of proceeds and collections as may be
necessary to maintain a reserve of sufficient funds for the proper operation,
management, maintenance and disposition of the related REO Property (including
without limitation the creation of a reasonable reserve for repairs,
replacements and necessary capital improvements and other related expenses),
such reserve not to exceed an amount sufficient to cover such items to be
incurred during the following twelve-month period.

                  (d) The Special Servicer shall keep and maintain separate
records, on a property-by-property basis, for the purpose of accounting for all
deposits to, and withdrawals from, the REO Account pursuant to Section 3.16(b)
or (c).

                  SECTION 3.17  Management of REO Property; Independent
                                Contractors.

                  (a) Prior to the acquisition of title to any Mortgaged
Property securing a Defaulted Mortgage Loan, the Special Servicer shall review
the operation of such Mortgaged Property and determine the nature of the income
that would be derived from such property if it were acquired by the Trust Fund.
If the Special Servicer determines from such review, in its good faith and
reasonable judgment, that:

                          (i) None of the income from Directly Operating such
             Mortgaged Property would be subject to tax as "net income from
             foreclosure property" within the meaning of the REMIC Provisions or
             would be subject to the tax imposed on "prohibited transactions"
             under Section 860F of the Code (either such tax referred to herein
             as an "REO Tax"), such Mortgaged Property may be Directly Operated
             by the Special Servicer as REO Property;

                          (ii) Directly Operating such Mortgaged Property as an
             REO Property could result in income from such property that would
             be subject to an REO Tax, but that a lease of such property to
             another party to operate such property, or the performance of some
             services by an Independent Contractor with respect to such
             property, or another method of operating such property would not
             result in income subject to an REO Tax, then the Special Servicer
             may (provided, that in the good faith and reasonable judgment of
             the Special Servicer, it is commercially feasible) acquire such
             Mortgaged Property as REO Property and so lease or operate such REO
             Property; or

                          (iii) Directly Operating such property as REO Property
             could result in income subject to an REO Tax and, in the good faith
             and reasonable judgment of the Special Servicer, that no
             commercially feasible means exists to operate such property as REO
             Property without the Trust Fund incurring or possibly incurring an
             REO Tax on income from such property, the Special Servicer shall
             deliver to the Trustee, in writing, a

                                      110
<PAGE>

             proposed plan (the "Proposed Plan") to manage such property as REO
             Property. Such plan shall include potential sources of income, and
             to the extent commercially feasible, estimates of the amount of
             income from each such source. Within a reasonable period of time
             after receipt of such plan, the Trustee shall consult with the
             Special Servicer and shall advise the Special Servicer of the Trust
             Fund's federal income tax reporting position with respect to the
             various sources of income that the Trust Fund would derive under
             the Proposed Plan. In addition, the Trustee shall (to the maximum
             extent possible) advise the Special Servicer of the estimated
             amount of taxes that the Trust Fund would be required to pay with
             respect to each such source of income. After receiving the
             information described in the two preceding sentences from the
             Trustee, the Special Servicer shall either (A) implement the
             Proposed Plan (after acquiring the respective Mortgaged Property as
             REO Property) or (B) manage and operate such property in a manner
             that would not result in the imposition of an REO Tax on the income
             derived from such property.

                  The Special Servicer's decision as to how each REO Property
shall be managed and operated shall in any event be based on the good faith and
reasonable judgment of the Special Servicer as to which means would (to the
extent commercially feasible) maximize the net after-tax REO Revenues received
by the Trust Fund with respect to such property without materially and adversely
affecting the Special Servicer's ability to sell such REO Property in accordance
with this Agreement and, to the extent consistent with the foregoing, in
accordance with the Servicing Standard. Both the Special Servicer and the
Trustee may consult with counsel knowledgeable in such matters at the expense of
the Trust Fund in connection with determinations required under this Section
3.17(a). Neither the Special Servicer nor the Trustee shall be liable to the
Certificateholders, the Trust Fund, the other parties hereto or each other for
errors in judgment made in good faith in the reasonable exercise of their
discretion while performing their respective responsibilities under this Section
3.17(a) or, to the extent it relates to federal income tax consequences for the
Trust Fund, Section 3.17(b) below. Nothing in this Section 3.17(a) is intended
to prevent the sale of a Defaulted Mortgage Loan or REO Property pursuant to the
terms and subject to the conditions of Section 3.18.

                  (b) If title to any REO Property is acquired, the Special
Servicer shall manage, conserve, protect and operate such REO Property for the
benefit of the Certificateholders solely for the purpose of its prompt
disposition and sale in a manner that 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, except as permitted by Section 3.17(a), result in the receipt by
the Trust Fund 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. Subject to the
foregoing, however, the Special Servicer shall have full power and authority to
do any and all things in connection therewith as are in the best interests of
and for the benefit of the Certificateholders (as determined by the Special
Servicer in its good faith and reasonable judgment) and, consistent therewith,
shall withdraw from the REO Account, to the extent of amounts on deposit therein
with respect to each REO Property, funds necessary for the proper operation,
management, maintenance and disposition of such REO Property, including, without
limitation:

                                      111
<PAGE>

                          (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;

                          (iii) any ground rents in respect of such REO
             Property; and

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

To the extent that amounts on deposit in the REO Account in respect of any REO
Property are insufficient for the purposes set forth in the prior sentence with
respect to such REO Property, the Special Servicer shall advance such amount as
is necessary for such purposes (which advances shall be Servicing Advances)
unless (as evidenced by an Officer's Certificate delivered to the Trustee) such
advances would, if made, constitute Nonrecoverable Servicing Advances; provided,
however, that the Special Servicer shall make any such Servicing Advance if it
is a necessary fee or expense incurred in connection with the defense or
prosecution of legal proceedings and such advance will be deemed to constitute a
recoverable Servicing Advance.

                  (c) The Special 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 may
             not be inconsistent herewith and shall reflect an agreement reached
             at arm's length;

                          (ii) the fees of such Independent Contractor (which
             shall be an expense of the Trust Fund) shall be reasonable and
             customary in light of the nature and locality of the REO Property;

                          (iii) any such contract shall require, or shall be
             administered to require, that the Independent Contractor (A) pay,
             out of related REO Revenues, all costs and expenses incurred in
             connection with the operation and management of such REO Property,
             including, without limitation, those listed in subsection (b)
             hereof, and (B) remit all related REO Revenues (net of its fees and
             such costs and expenses) to the Special Servicer;

                          (iv) none of the provisions of this Section 3.17(c)
             relating to any such contract or to actions taken through any such
             Independent Contractor shall be deemed to relieve the Special
             Servicer of any of its duties and obligations hereunder with
             respect to the operation and management of any such REO Property;
             and

                          (v) the Special 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 Special 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

                                      112
<PAGE>

indemnification of the Special Servicer by such Independent Contractor, and
nothing in this Agreement shall be deemed to limit or modify such
indemnification.

                  SECTION 3.18  Sale of Defaulted Mortgage Loans and REO
                                Properties.

                  (a) The parties hereto may sell or purchase, or permit the
sale or purchase of, a Mortgage Loan, Companion Loan or REO Property only on the
terms and subject to the conditions set forth in this Section 3.18 or as
otherwise expressly provided in or contemplated by Sections 2.03(a) and 9.01,
and in the case of any Companion Loan, the related Intercreditor Agreement.

                  (b) In the event that any Mortgage Loan or Loan Group becomes
a Defaulted Mortgage Loan and the Special Servicer has determined in good faith
that such Defaulted Mortgage Loan will become subject to foreclosure
proceedings, the Special Servicer shall promptly so notify, in writing, the
Master Servicer and the Trustee, and the Trustee shall so notify, in writing,
within 10 days after receipt of its notice, the Holders of the Controlling Class
(including, in the case of any Loan Group, the holders of the Controlling Class
of Class S Certificates). The Majority Certificateholder of the Controlling
Class (including, in the case of any Loan Group, the holders of the Controlling
Class of Class S Certificates) may at its (or their) option purchase from the
Trust Fund, at a price equal to the Purchase Price, any such Defaulted Mortgage
Loan (which shall include the Mortgage Loan and all Companion Loans if a Loan
Group is involved). The Purchase Price for any such Defaulted Mortgage Loan
purchased hereunder shall be deposited into the Collection Account, and the
Trustee, upon receipt of an Officer's Certificate from the Master Servicer to
the effect that such deposit has been made, shall release or cause to be
released to the Majority Certificateholder of such Controlling Class (or any
designee thereof), the related Mortgage File, and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as shall
be necessary to vest in the Majority Certificateholder of such Controlling Class
(or any designee thereof), ownership of such Defaulted Mortgage Loan (subject,
in the case of an Additional Servicing Fee Mortgage Loan to the rights of the
applicable Designated Sub-Servicer to sub-service such Mortgage Loan and the
rights of the applicable Designated Sub-Servicer, Archon Financial, L.P. and the
Master Servicer, as applicable, to receive or retain their applicable portion of
the Additional Servicing Fee, in each case, pursuant to the related Designated
Sub-Servicer Agreement). In connection with any such purchase, the Special
Servicer shall deliver the related Credit File to such Certificateholder(s).
Notwithstanding the above, if such Defaulted Mortgage Loan is a Loan Group, the
purchase option shall first be solely exercisable by the Majority
Certificateholder of the Controlling Class of the respective Loan Group's Class
S Certificates if any such class is outstanding. If the Majority
Certificateholder of the related Class S Certificates does not exercise such
option within the time limits set forth in this Section 3.18, the purchase
option will then be exercisable by the Majority Certificateholder of the
Controlling Class of Certificates other than the Class S Certificates pursuant
to this Section 3.18(b).

                  (c) If the Majority Certificateholder of the Controlling Class
has not purchased any such Defaulted Mortgage Loan within (x) 15 days of its
having received notice in respect thereof pursuant to the immediately preceding
subsection and, (y) in the case of any Defaulted Mortgage Loan that is a Loan
Group, an additional 15 day period allowed for the Majority Certificateholder of
the Controlling Class of Certificates other than the Class S

                                      113
<PAGE>

Certificates to exercise its purchase option on any Defaulted Mortgage Loan that
was a Loan Group if the related Class S Certificateholder does not exercise its
purchase option as set forth in Section 3.18(b) either the Special Servicer or,
subject to the Special Servicer's prior rights in such regard, the Master
Servicer may at its option, within 15 days after receipt of such notice,
purchase such Defaulted Mortgage Loan from the Trust Fund, at a price equal to
the Purchase Price. The Purchase Price for any such Defaulted Mortgage Loan
purchased hereunder shall be deposited into the Collection Account except that,
in the case of any purchase by a Class S Certificateholder, the portion of the
Purchase Price for any Loan Group attributable to the related Companion Loan
shall be deposited directly into the related Companion Loan Subaccount, and the
Trustee, upon receipt of an Officer's Certificate from the Master Servicer to
the effect that such deposit has been made, shall release or cause to be
released to the Master Servicer or the Special Servicer, as applicable, the
related Mortgage File, and shall execute and deliver at the expense of the
purchasing party such instruments of transfer or assignment, in each case
without recourse, representation or warranty, as shall be necessary to vest in
the Master Servicer or the Special Servicer, as applicable, such Defaulted
Mortgage Loan (subject, in the case of an Additional Servicing Fee Mortgage Loan
to the rights of the applicable Designated Sub-Servicer to sub-service such
Mortgage Loan and the rights of the applicable Designated Sub-Servicer, Archon
Financial, L.P. and the Master Servicer, as applicable, to receive or retain
their applicable portion of the Additional Servicing Fee, in each case, pursuant
to the related Designated Sub-Servicer Agreement). In connection with any such
purchase by the Master Servicer, the Special Servicer shall deliver the related
Credit File to the Master Servicer.

                  (d) The Special Servicer may offer to sell any such Defaulted
Mortgage Loan not otherwise purchased by the Majority Certificateholder of the
Controlling Class (or the Controlling Class of Class S Certificates), the Master
Servicer or the Special Servicer pursuant to subsection (b) or (c) above (and
subject to the rights of Designated Sub-Servicers as set forth therein), if and
when the Special Servicer determines, consistent with the Servicing Standard,
that such a sale would produce a greater recovery to Certificateholders on a
present value basis than would liquidation of the related Mortgaged Property.
Such offering shall be made in a commercially reasonable manner (which, for
purposes hereof, includes an offer to sell without representation or warranty
other than customary warranties of title, loan status, condition and similar
customary matters, if liability for breach thereof is limited to recourse
against the Trust Fund) for a period of not less than 10 days or more than 90
days. Unless the Special Servicer determines that acceptance of any offer would
not be in the best economic interests of the Trust Fund, the Special Servicer
shall accept the highest cash offer received from any Person that constitutes a
fair price for such Mortgage Loan or Loan Group. In the absence of any offer
determined as provided below to be fair, the Special Servicer shall proceed with
respect to such Defaulted Mortgage Loan in accordance with Section 3.09 and,
otherwise, in accordance with the Servicing Standard.

                  The Special Servicer shall use reasonable efforts to solicit
offers for each REO Property on behalf of the Certificateholders, in such manner
as will be reasonably likely to realize a fair price within the time period
provided for by Section 3.16(a). The Special Servicer shall accept the first
(and, if multiple bids are contemporaneously received, highest) cash bid
received from any Person that constitutes a fair price for such REO Property. If
the Special Servicer determines, in its good faith and reasonable judgment, that
it will be unable to realize a fair price for any REO Property within the time
constraints imposed by Section 3.16(a), then the

                                      114
<PAGE>

Special Servicer shall dispose of such REO Property upon such terms and
conditions as the Special Servicer shall deem necessary and desirable to
maximize the recovery thereon under the circumstances and, in connection
therewith, shall accept the highest outstanding cash bid, regardless of from
whom received. The Liquidation Proceeds (net of related Liquidation Expenses)
for any REO Property purchased hereunder shall be deposited in the Collection
Account, except that any portion of proceeds consisting of Excess Liquidation
Proceeds shall be deposited in the Excess Liquidation Proceeds Reserve Account.

                  The Special Servicer shall give the Trustee and the Master
Servicer not less than three Business Days' prior written notice of its
intention to sell any Defaulted Mortgage Loan or REO Property. No Interested
Person shall be obligated to submit a bid to purchase any Defaulted Mortgage
Loan or REO Property, and notwithstanding anything to the contrary herein,
neither the Trustee, in its individual capacity, nor any of its Affiliates may
bid for or purchase any Defaulted Mortgage Loan or any REO Property pursuant
hereto.

                  (e) Whether any cash bid constitutes a fair price for any
Defaulted Mortgage Loan or REO Property, as the case may be, for purposes of
Section 3.18(d), shall be determined by the Special Servicer, if the highest
bidder is a Person other than an Interested Person, and by the Trustee, if the
highest bidder is an Interested Person; provided, however, that no bid from an
Interested Person shall constitute a fair price unless (i) it is the highest bid
received and (ii) at least two other bids are received from independent third
parties. In determining whether any offer received from an Interested Person
represents a fair price for any such Mortgage Loan, Loan Group or REO Property,
the Trustee shall be supplied with and shall rely on the most recent Appraisal
or updated Appraisal conducted in accordance with this Agreement within the
preceding 12-month period or, in the absence of any such Appraisal, on a
narrative appraisal prepared by a Qualified Appraiser retained by the Special
Servicer. Such appraiser shall be selected by the Special Servicer if the
Special Servicer is not making an offer with respect to a Defaulted Mortgage
Loan or REO Property and shall be selected by the Master Servicer if the Special
Servicer is making such an offer. The cost of any such narrative appraisal shall
be covered by, and shall be reimbursable as, a Servicing Advance. In determining
whether any offer from a Person other than an Interested Person constitutes a
fair price for any such Mortgage Loan, Loan Group or REO Property, the Special
Servicer shall take into account (in addition to the results of any Appraisal,
updated Appraisal or narrative Appraisal that it may have obtained pursuant to
this Agreement within the prior 12 months), and in determining whether any offer
from an Interested Person constitutes a fair price for any such Mortgage Loan or
REO Property, any appraiser shall be instructed to take into account, as
applicable, among other factors, the period and amount of any delinquency on the
affected Defaulted Mortgage Loan, the occupancy level and physical condition of
the Mortgaged Property or REO Property, the state of the local economy and the
obligation to dispose of any REO Property within the time period specified in
Section 3.16(a). The Purchase Price for any Defaulted Mortgage Loan or REO
Property shall in all cases be deemed a fair price.

                  (f) Subject to subsections (a) through (e) above, the Special
Servicer shall act on behalf of the Trust Fund in negotiating and taking any
other action necessary or appropriate in connection with the sale of any
Defaulted Mortgage Loan or REO Property, and the collection of all amounts
payable in connection therewith. In connection therewith, the Special Servicer
may charge prospective offerors, and may retain, fees that approximate the
Special Servicer's actual

                                      115
<PAGE>

costs in the preparation and delivery of information pertaining to such sales or
exchanging offers without obligation to deposit such amounts into the Collection
Account. Any sale of a Defaulted Mortgage Loan or any REO Property shall be
final and without recourse to the Trustee or the Trust Fund (except such
recourse to the Trust Fund imposed by those representations and warranties
typically given in such transactions, any prorations applied thereto and any
customary closing matters), and if such sale is consummated in accordance with
the terms of this Agreement, none of the Special Servicer, the Master Servicer,
the Depositor or the Trustee shall have any liability to any Certificateholder
with respect to the purchase price therefor accepted by the Special Servicer or
the Trustee.

                  (g) Any sale of a Defaulted Mortgage Loan or any REO Property
shall be for cash only (unless, as evidenced by an Opinion of Counsel, a sale
for other consideration will not cause an Adverse REMIC Event).

                  (h) Notwithstanding any of the foregoing paragraphs of this
Section 3.18, the Special Servicer shall not be obligated to accept the highest
cash offer if the Special Servicer determines, in its reasonable and good faith
judgment, that rejection of such offer would be in the best interests of the
Certificateholders, and the Special Servicer may accept a lower cash offer (from
any Person other than itself or an Affiliate) if it determines, in its
reasonable and good faith judgment, that acceptance of such offer would be in
the best interests of the Certificateholders (for example, if the prospective
buyer making the lower offer is more likely to perform its obligations or the
terms offered by the prospective buyer making the lower offer are more
favorable).

                  SECTION 3.19  Additional Obligations of the Master Servicer
                                and the Special Servicer.

                  (a) In connection with each Adjustable Rate Mortgage Loan
(and, if and to the extent applicable, any successor REO Loan), the Master
Servicer shall calculate adjustments in the Mortgage Rate and the Monthly
Payment and shall notify the Mortgagor of such adjustments, all in accordance
with the Mortgage Note and applicable law. In the event the Index for any
Adjustable Rate Mortgage Loan (or successor REO Loan) is not published or is
otherwise unavailable, the Master Servicer shall select a comparable alternative
index with respect to such Adjustable Rate Mortgage Loan (or successor REO Loan)
over which it has no direct control, which is readily verifiable and which is
acceptable under the terms of the related Mortgage Note.

                  (b) The Master Servicer and the Special Servicer, as
applicable, shall each deliver to the other and to the Trustee (for inclusion in
the Mortgage File) copies of all Appraisals, environmental reports and
engineering reports (or, in each case, updates thereof) obtained with respect to
any Mortgaged Property or REO Property.

                  (c) No more frequently than once per calendar month, the
Special Servicer may require the Master Servicer, and the Master Servicer shall
be obligated, subject to the second following paragraph, to reimburse the
Special Servicer for any Servicing Advances made by but not previously
reimbursed to the Special Servicer, and to pay the Special Servicer interest
thereon at the Reimbursement Rate from the date made to, but not including, the
date of

                                      116
<PAGE>

reimbursement. Such reimbursement and any accompanying payment of Advance
Interest shall be made within ten (10) days of the request therefor by wire
transfer of immediately available funds to an account designated by the Special
Servicer. Upon the Master Servicer's reimbursement to the Special Servicer of
any Servicing Advance and payment to the Special Servicer of interest thereon,
all in accordance with this Section 3.19(c), the Master Servicer shall for all
purposes of this Agreement be deemed to have made such Servicing Advance at the
same time as the Special Servicer originally made such Advance, and accordingly,
the Master Servicer shall be entitled to reimbursement for such Advance,
together with interest thereon, at the same time, in the same manner and to the
same extent as the Master Servicer would otherwise have been entitled if it had
actually made such Servicing Advance.

                  Notwithstanding anything to the contrary contained in this
Agreement, if the Special Servicer is required under this Agreement to make any
Servicing Advance but does not desire to do so, the Special Servicer may, in its
sole discretion, request that the Master Servicer make such Advance, such
request to be made in writing and in a timely manner that does not materially
and adversely affect the interests of any Certificateholder. Subject to the
following paragraph, the Master Servicer shall have the obligation to make any
such Servicing Advance that it is requested by the Special Servicer to make
within ten days of the Master Servicer's receipt of such request. The Special
Servicer shall be relieved of any obligations with respect to an Advance that it
requests the Master Servicer to make (regardless of whether or not the Master
Servicer shall make such Advance). The Master Servicer shall be entitled to
reimbursement for any Servicing Advance made by it at the direction of the
Special Servicer, together with Advance Interest thereon, at the same time, in
the same manner and to the same extent as the Master Servicer is entitled with
respect to any other Servicing Advance made thereby. If the Special Servicer
makes any Servicing Advances in accordance with the terms of this Agreement, the
Special Servicer shall notify the Master Servicer in writing within one Business
Day of any such Servicing Advance.

                  Notwithstanding the foregoing provisions of this Section
3.19(c), the Master Servicer shall not be required to make at the Special
Servicer's direction, or to reimburse the Special Servicer for, any Servicing
Advance if the Master Servicer determines in its reasonable, good faith judgment
that the Servicing Advance which the Special Servicer is directing the Master
Servicer to make or to reimburse to the Special Servicer hereunder either (y)
although not characterized by the Special Servicer as a Nonrecoverable Servicing
Advance, is or would be, if made, a Nonrecoverable Servicing Advance, or (z) the
making of such advance was or would be in violation of the Servicing Standard or
the terms and conditions of this Agreement. The Master Servicer shall notify the
Special Servicer in writing of such determination. Such notice shall not
obligate the Special Servicer to make any such proposed Servicing Advance.

                  (d) Upon the earliest of (i) the date on which any Mortgage
Loan or Loan Group becomes a Modified Mortgage Loan, (ii) the 90th day following
the occurrence of any uncured delinquency in Monthly Payments with respect to
any Mortgage Loan or Companion Loan, (iii) the date on which a receiver is
appointed and continues in such capacity in respect of the Mortgaged Property
securing any Mortgage Loan or Loan Group and (iv) the date on which the
Mortgaged Property securing any Mortgage Loan or Loan Group becomes an REO
Property (each such Mortgage Loan, Loan Group and any related REO Loan, a
"Required Appraisal Loan"), the Special Servicer, shall request and, within 30
days of the occurrence of such event

                                      117
<PAGE>

(or such longer period as the Special Servicer is (as certified thereby to the
Trustee in writing) diligently and in good faith proceeding to obtain such)
obtain an Appraisal of the related Mortgaged Property; provided, however, that
such Appraisal shall not be required if an Appraisal of the Mortgaged Property
had previously been obtained within the prior twelve months, unless the Special
Servicer determines that such previously obtained Appraisal is materially
inaccurate. The cost of any such Appraisal shall be covered by, and reimbursable
as, a Servicing Advance.

                  With respect to each Required Appraisal Loan (unless such loan
has become a Corrected Mortgage Loan and no other Servicing Transfer Event, or
other event that would cause the loan to be a Required Appraisal Loan, has
occurred), the Special Servicer shall, within 30 days of each anniversary of
such loan's becoming a Required Appraisal Loan, order an update of the prior
Appraisal (the cost of which will be covered by, and reimbursable as, a
Servicing Advance). Based upon such Appraisal, the Special Servicer shall
determine and report to the Trustee the Appraisal Reduction Amount, if any, with
respect to such loan. The Special Servicer shall deliver a copy of any such
Appraisal to the Master Servicer.

                  Notwithstanding the foregoing, if a Required Appraisal Loan
has a principal balance of less than $2,000,000, a desktop estimation of value
may be substituted for any Appraisal otherwise required pursuant to this Section
3.19(d).

                  (e) The Master Servicer shall deliver to the Trustee (x) for
deposit in the Certificate Distribution Account on each Master Servicer
Remittance Date, without any right of reimbursement therefor, an amount equal to
the aggregate of all Balloon Payment Interest Shortfalls incurred in connection
with Balloon Payments received in respect of the Mortgage Loans during the most
recently ended Collection Period and (y) for deposit in the applicable Companion
Loan Distribution Account on each Master Servicer Remittance Date, without any
right of reimbursement therefor, an amount equal to the aggregate of all Balloon
Payment Interest Shortfalls incurred in connection with Balloon Payments
received in respect of the related Companion Loan during the most recently ended
Collection Period.

                  (f) The Master Servicer shall deliver to the Trustee (x) for
deposit in the Certificate Distribution Account on each Master Servicer
Remittance Date, without any right of reimbursement therefor, an amount equal to
the lesser of (i) the aggregate of all Prepayment Interest Shortfalls incurred
in connection with Principal Prepayments received in respect of the Mortgage
Loans during the most recently ended Collection Period, and (ii) the aggregate
Master Servicing Fees accrued on the Mortgage Loans received by the Master
Servicer during such Collection Period and (y) for deposit in the applicable
Companion Loan Distribution Account on each Master Servicer Remittance Date,
without any right of reimbursement therefor, an amount equal to the lesser of
(i) the aggregate of all Prepayment Interest Shortfalls incurred in connection
with Principal Prepayments received in respect of the applicable Companion Loans
during the most recently ended Collection Period, and (ii) the aggregate Master
Servicing Fees accrued on such Companion Loan received by the Master Servicer
during such Collection Period.

                  (g) With respect to all ARD Loans, the Master Servicer shall
apply all Monthly Payments and any other sums due, in accordance with the terms
of the related ARD Loan.

                                      118
<PAGE>

                  (h) Subject to Section 3.20(a)(iv), with respect to all ARD
Loans, the Master Servicer and the Special Servicer shall not take any
enforcement action with respect to the payment of Excess Interest or principal
in excess of the principal component of the constant Monthly Payment, other than
request for collection, until the maturity date of the related Mortgage Loan.
The foregoing shall not limit the Servicer and Special Servicer's obligation to
establish or direct the related Mortgagor to establish a Lock-Box Account
pursuant to Section 3.24.

                  (i) The Master Servicer shall be entitled to waive the
application of any provision in any ARD Loan that requires that the property
manager of the related Mortgaged Property be discharged if such ARD Loan is not
paid in full on its Anticipated Repayment Date.

                  (j) With respect to each Mortgage Loan and Companion Loan that
upon the occurrence of certain events permits the Master Servicer to apply the
proceeds of the release of any earnout reserve to the exercise of a Defeasance
Option, the Master Servicer shall only exercise such Defeasance Option in
accordance with Section 3.08 of this Agreement.

                  (k) To the extent consistent with the terms of the applicable
Mortgage Loan or Companion Loan, the Master Servicer shall exercise its option
to apply any proceeds of the release of the related earnout reserve to the
prepayment or defeasance, as applicable, of such Mortgage Loan or Loan Group.

                  (l) Upon the application of the proceeds of the release of any
earnout reserve to the prepayment of the related Mortgage Loan or Loan Group,
the Master Servicer shall calculate, based upon the Maturity Date, Mortgage Rate
and remaining outstanding principal balance of such Mortgage Loan or Loan Group,
a revised schedule upon which the remaining amount of principal and interest due
upon such Mortgage Loan or Loan Group shall be amortized until its Maturity
Date. The Master Servicer shall deliver a copy of such revised amortization
schedule to the related Mortgagor with an instruction to thereafter make Monthly
Payments in accordance with the revised schedule.

                  (m) The Master Servicer shall provide written direction to
each lessor under a Ground Lease requesting that upon any default by the lessee,
notice thereof be provided to the Master Servicer to the extent required by the
Ground Lease.

                  (n) [Intentionally Omitted]

                  (o) The Master Servicer and the Special Servicer shall take
all such action as may be required to comply with the terms and conditions
precedent to payment of claims under the Environmental Policy and in order to
maintain, in full force and effect, such policy. Neither the Master Servicer nor
the Special Servicer shall agree to amend the Environmental Policy unless it
shall have obtained Rating Agency Confirmation with respect to such amendment.
In addition, the Master Servicer shall notify each Rating Agency of any claim
under the Environmental Policy.

                  (p) With respect to any fees payable to a Rating Agency in
connection with an assumption the Master Servicer or Special Servicer, as
applicable, shall not approve any assumption without requiring the Mortgagor to
pay any fees associated with any Rating Agency

                                      119
<PAGE>

Confirmation, to the extent permitted or required under the applicable Mortgage
Loan or Companion Loan documents and otherwise consistent with the Servicing
Standard.

                  SECTION 3.20  Modifications, Waivers, Amendments and Consents.

                  (a) The Master Servicer and the Special Servicer each may
agree to any modification, waiver or amendment of any term of, forgive interest
on and principal of, capitalize interest on, permit the release, addition or
substitution of collateral securing, and/or permit the release of the Mortgagor
on or any guarantor of any Mortgage Loan or Loan Group it is required to service
and administer hereunder, without the consent of the Trustee, any
Certificateholder, subject, however, to each of the following limitations,
conditions and restrictions:

                          (i) other than as provided in Sections 3.02 and 3.08,
             the Master Servicer (in such capacity) shall not agree to any
             modification, waiver or amendment of any term of, or take any of
             the other acts referenced in this Section 3.20(a) with respect to,
             any Mortgage Loan or Loan Group that would (A) affect the amount or
             timing of any related payment of principal, interest or other
             amount payable thereunder, (B) affect the obligation of the related
             Mortgagor to pay any Prepayment Premium or permit a Principal
             Prepayment during any period when the terms of the Mortgage Loan or
             Loan Group prohibit the making of Principal Prepayments or, (C) in
             the Master Servicer's good faith and reasonable judgment,
             materially impair the security for such Mortgage Loan or Loan Group
             or reduce the likelihood of timely payment of amounts due thereon;
             the Special Servicer (in such capacity) may, however, agree to any
             modification, waiver or amendment of any term of, or take any of
             the other acts referenced in this Section 3.20(a) with respect to,
             a Specially Serviced Mortgage Loan that would have any such effect,
             but only if, in the Special Servicer's reasonable and good faith
             judgment, a material default on such Mortgage Loan or Loan Group
             has occurred or a default in respect of payment on such Mortgage
             Loan or Loan Group is reasonably foreseeable, and such
             modification, waiver, amendment or other action is reasonably
             likely to produce a greater recovery to Certificateholders on a
             present value basis, than would liquidation;

                          (ii) any such action taken by the Special Servicer
             shall be accompanied by an Officer's Certificate to such effect and
             to which is attached the present value calculation which
             establishes the basis for such determination, a copy of which shall
             be delivered to the Trustee for delivery to the Rating Agencies;

                          (iii) neither the Master Servicer nor the Special
             Servicer may extend the Stated Maturity Date of any Mortgage Loan
             or Companion Loan beyond the date that is two years prior to the
             Rated Final Distribution Date and, in the case of any Mortgage Loan
             or Companion Loan that is secured solely by a Ground Lease, the
             Master Servicer or the Special Servicer, as the case may be, shall
             give due consideration to the remaining term of such Ground Lease
             prior to extending the Stated Maturity Date of the Mortgage Loan or
             Companion Loan;

                          (iv) neither the Master Servicer nor the Special
             Servicer shall make or permit any modification, waiver or amendment
             of any term of, or take any of the other

                                      120
<PAGE>

             acts referenced in this Section 3.20(a) or clause (h) of Section
             3.19 with respect to, any Mortgage Loan or Companion Loan that
             would (A) cause REMIC I, REMIC II or REMIC III to fail to qualify
             as a REMIC under the Code or (subject to Section 10.01(f)) result
             in the imposition of any tax on "prohibited transactions" or
             "contributions" after the Startup Day of any such REMIC under the
             REMIC Provisions or (B) cause any Mortgage Loan or Companion Loan
             to cease to be a "qualified mortgage" within the meaning of Section
             860G(a)(3) of the Code (neither the Master Servicer nor the Special
             Servicer shall be liable for judgments as regards decisions made
             under this subsection which were made in good faith and, unless it
             would constitute bad faith or negligence to do so, each of the
             Master Servicer and the Special Servicer may rely on opinions of
             counsel in making such decisions);

                          (v) neither the Master Servicer nor the Special
             Servicer shall permit any Mortgagor to add or substitute any
             collateral for an outstanding Mortgage Loan or Loan Group, which
             collateral constitutes real property, unless the Master Servicer or
             the Special Servicer, as the case may be, shall have first
             determined, in its reasonable and good faith judgment, based upon
             an Environmental Assessment performed within the twelve months
             prior to such determination (and such additional environmental
             testing as the Master Servicer or Special Servicer, as the case may
             be, deems necessary and appropriate) prepared by an Independent
             Person who regularly conducts Environmental Assessments (and such
             additional environmental testing), at the expense of the Mortgagor,
             that such additional or substitute collateral is in compliance with
             applicable environmental laws and regulations and that there are no
             circumstances or conditions present with respect to such new
             collateral relating to the use, management or disposal of any
             Hazardous Materials for which investigation, testing, monitoring,
             containment, clean-up or remediation would be required under any
             then applicable environmental laws and/or regulations;

                          (vi) neither the Master Servicer nor the Special
             Servicer shall release or substitute any collateral securing an
             outstanding Mortgage Loan or Loan Group except as provided in
             Sections 3.08 and 3.09(d) and except in the case of a release where
             (A) the use of the collateral to be released will not, in the
             Master Servicer's or Special Servicer's, as the case may be, good
             faith and reasonable judgment, materially and adversely affect the
             Net Operating Income being generated by or the use of the related
             Mortgaged Property, (B) there is a corresponding principal paydown
             of such Mortgage Loan or Loan Group in an amount at least equal to,
             or a delivery of substitute collateral with an Appraised Value at
             least equal to, the Appraised Value of the collateral to be
             released, (C) the remaining Mortgaged Property and any substitute
             collateral is, in the Master Servicer's or Special Servicer's, as
             the case may be, good faith and reasonable judgment, adequate
             security for the remaining Mortgage Loan or Loan Group and (D) the
             Master Servicer or Special Servicer, as applicable, has received
             Rating Agency Confirmation with respect to such release or
             substitution; provided that (x) the limitations, conditions and
             restrictions set forth in clauses (i) through (vi) above shall not
             apply to any modification of any term of any Mortgage Loan or Loan
             Group or any other acts referenced in this Section 3.20(a) that is
             required under the terms of such Mortgage Loan or Loan Group in
             effect on the Closing Date and that is solely within the control of
             the related Mortgagor, and (y) notwithstanding clauses (i) through
             (vi) above, neither the

                                      121
<PAGE>

             Master Servicer nor the Special Servicer shall be required to
             oppose the confirmation of a plan in any bankruptcy or similar
             proceeding involving a Mortgagor if in their reasonable and good
             faith judgment such opposition would not ultimately prevent the
             confirmation of such plan or one substantially similar. Neither the
             Master Servicer nor the Special Servicer may extend the Maturity
             Date on any Mortgage Loan or Loan Group except pursuant to this
             Section 3.20(a) or as otherwise required under the related loan
             documents; and

                          (vii) the Master Servicer shall not consent to any
             assumption of a Mortgage Loan or Loan Group or release of any
             earnout reserve amounts with respect to any Specified Earnout
             Reserve Loan unless the Special Servicer shall have approved such
             assumption or release in writing.

                  (b) Neither the Master Servicer nor the Special Servicer shall
have any liability to the Trust Fund, the Certificateholders or any other Person
if its analysis and determination that the modification, waiver, amendment or
other action contemplated by Section 3.20(a) is reasonably likely to produce a
greater recovery to Certificateholders on a present value basis than would
liquidation, should prove to be wrong or incorrect, so long as the analysis and
determination were made on a reasonable basis in good faith by the Master
Servicer or Special Servicer and the Master Servicer or Special Servicer was not
negligent in ascertaining the pertinent facts. The Master Servicer shall not
have any liability to the Trust Fund, the Certificateholders or any other Person
with respect to the Special Servicer's approval, disapproval or delay in
processing any assumption or earnout release as provided in Section
3.20(a)(vii).

                  (c) Any payment of interest, which is deferred pursuant to any
modification, waiver or amendment permitted hereunder, shall not, for purposes
hereof, including, without limitation, calculating monthly distributions to
Certificateholders, be added to the unpaid principal balance of the related
Mortgage Loan or Companion Loan, notwithstanding that the terms of such Mortgage
Loan or Companion Loan or such modification, waiver or amendment so permit.

                  (d) The Master Servicer and, with respect to a Specially
Serviced Mortgaged Loan, the Special Servicer each may, as a condition to its
granting any request by a Mortgagor for consent, modification, waiver or
indulgence or any other matter or thing, the granting of which is within the
Master Servicer's or the Special Servicer's discretion pursuant to the terms of
the instruments evidencing or securing the related Mortgage Loan or Loan Group
and is permitted by the terms of this Agreement, require that such Mortgagor pay
to it, as additional servicing compensation, a reasonable or customary fee (not
to exceed 1.0% of the unpaid principal balance of the related Mortgage Loan or
Loan Group) for the additional services performed in connection with such
request, together with any related costs and expenses incurred by it.

                  (e) Except for waivers of Penalty Charges and notice periods,
all material modifications, waivers and amendments of the Mortgage Loans or Loan
Groups entered into pursuant to this Section 3.20 shall be in writing.

                  (f) Each of the Master Servicer and the Special Servicer shall
notify the Trustee and such other party, in writing, of any modification, waiver
(other than a waiver of Penalty Charges) or amendment of any term of any
Mortgage Loan or Loan Group and the date thereof, and shall deliver to the
Trustee or the related Custodian for deposit in the related Mortgage File, an
original counterpart of the agreement relating to such modification, waiver or
amendment, promptly (and in any event within 10 Business Days) following the
execution thereof.

                  SECTION 3.21  Transfer of Servicing Between Master Servicer
                                and Special Servicer; Record Keeping.

                  (a) Upon determining that a Servicing Transfer Event has
occurred with respect to any Mortgage Loan or Loan Group and if the Master
Servicer is not also the Special Servicer, the Master Servicer shall promptly
give notice thereof, and deliver the related Servicing File, to the Special
Servicer and shall use reasonable efforts to provide the Special Servicer with
all information, documents (or copies thereof) and records (including records
stored electronically on computer tapes, magnetic discs and the like) relating
to the Mortgage Loan or Loan Group and reasonably requested by the Special
Servicer to enable it to assume its functions hereunder with respect thereto
without acting through a Sub-Servicer. The Master Servicer shall use reasonable
efforts to comply with the preceding sentence within five Business Days of the
occurrence of each related Servicing Transfer Event. The Special Servicer may,
as to any delinquent Mortgage Loan or Loan Group, prior to the occurrence of a
Servicing Transfer Event with respect thereto, request and obtain the foregoing
documents and information.

                  Upon determining that a Specially Serviced Mortgage Loan has
become a Corrected Mortgage Loan and if the Master Servicer is not also the
Special Servicer, the Special Servicer shall promptly give notice thereof, and
return the related Servicing File, to the Master Servicer and upon giving such
notice, and returning such Servicing File, to the Master Servicer, the Special
Servicer's obligation to service such Mortgage Loan or Loan Group, and the
Special Servicer's right to receive the Special Servicing Fee with respect to
such Mortgage Loan or Loan Group, shall terminate, and the obligations of the
Master Servicer to service and administer such Mortgage Loan or Loan Group in
accordance with this Agreement shall resume.

                  Notwithstanding other provisions in this Agreement to the
contrary, the Master Servicer shall remain responsible for the billing and
collection, accounting, data collection, reporting and other basic Master
Servicer administrative functions with respect to Specially Serviced Mortgage
Loans, provided that the Special Servicer shall establish procedures for the
Master Servicer as to the application of receipts and tendered payments and
shall have the exclusive responsibility for and authority over all contacts with
and notices to Mortgagors and similar matters relating to each Specially
Serviced Mortgage Loan and the related Mortgaged Property.

                  (b) In servicing any Specially Serviced Mortgage Loans, the
Special Servicer shall provide to the Trustee originals of documents included
within the definition of "Mortgage File" for inclusion in the related Mortgage
File (with a copy of each such original to the Master Servicer), and copies of
any additional related Mortgage Loan or Loan Group information, including
correspondence with the related Mortgagor.

                  (c) Notwithstanding anything in this Agreement to the
contrary, in the event that the Master Servicer and the Special Servicer are the
same Person, all notices, certificates, information and consents required to be
given by the Master Servicer to the Special Servicer or vice versa shall be
deemed to be given without the necessity of any action on such Person's part.

                  SECTION 3.22  Sub-Servicing Agreements.

                  (a) The Master Servicer and the Special Servicer may each
enter into Sub-Servicing Agreements for the servicing and administration of all
or a part of the Mortgage Loans or Loan Groups for which it is responsible
hereunder, provided that, in each case, the Sub-Servicing Agreement: (i) is not
inconsistent with this Agreement and shall provide that the Sub-Servicer will
maintain errors and omissions insurance and fidelity bond coverage as required
of the Master Servicer or the Special Servicer (whichever retained it) under
Section 3.07 hereof; (ii) provides that if the Master Servicer or the Special
Servicer, as the case may be, shall for any reason no longer be the Master
Servicer or Special Servicer, as applicable, hereunder (including, without
limitation, by reason of an Event of Default or their termination hereunder),
the Trustee, its designee or any successor Master Servicer or Special Servicer
may thereupon assume all of the rights and, except to the extent they arose
prior to the date of assumption, obligations of the Master Servicer or the
Special Servicer, as the case may be, under such agreement; (iii) in the case of
a Sub-Servicing Agreement entered into by the Master Servicer, expressly or
effectively provides that (if the Master Servicer and the Special Servicer are
not the same Person) such agreement shall terminate with respect to any Mortgage
Loan or Loan Group serviced thereunder at the time such Mortgage Loan or Loan
Group becomes a Specially Serviced Mortgage Loan (provided that, if any
Additional Servicing Fee Mortgage Loan becomes a Specially Serviced Mortgage
Loan, the applicable Designated Sub-Servicer, Archon Financial, L.P. and the
Master Servicer, as the case may be, shall be entitled to continue to receive or
retain their applicable portion of the Additional Servicing Fee with respect to
such Mortgage Loan or Loan Group pursuant to the related Designated Sub-Servicer
Agreement); (iv) requires that the Master Servicer or the Special Servicer, as
the case may be, consent to any modification to the terms of a Mortgage Loan

(vi) in the case of a Sub-Servicing Agreement entered into by the Special
Servicer, relates only to Specially Serviced Mortgage Loans or REO Properties
and expressly or effectively provides that (if the Master Servicer and the
Special Servicer are not the same Person) such agreement shall terminate with
respect to any such Mortgage Loan or Loan Group that becomes a Corrected
Mortgage Loan. Termination penalties or fees incurred under any such
Sub-Servicing Agreement shall not be an obligation of, or expense chargeable to,
the Certificateholders or the Trust Fund. References in this Agreement to
actions taken or to be taken by the Master Servicer or the Special Servicer, as
the case may be, include actions taken or to be taken by a Sub-Servicer on
behalf of the Master Servicer or the Special Servicer, as the case may be; and,
in connection therewith, all amounts advanced by any Sub-Servicer to satisfy the
obligations of the Master Servicer or the Special Servicer, as the case may be,
hereunder to make Servicing Advances and Delinquency Advances shall be deemed to
have been advanced by the Master Servicer or the Special Servicer, as the case
may be, out of its own funds and, accordingly, such Advances shall be
recoverable by such Sub-Servicer in the same manner and out of the same funds as
if such Sub-Servicer were the Master Servicer or the Special Servicer, as the
case may be, and, for so long as they are outstanding, such Advances shall
accrue interest in accordance with Section 3.11(f) or Section

                                      124

4.03(d), as applicable, such interest to be allocable between the Master
Servicer or the Special Servicer, as the case may be, and such Sub-Servicer as
they may agree. For purposes of this Agreement, the Master Servicer and the
Special Servicer each shall be deemed to have received any payment when the
Sub-Servicer receives such payment.

                  (b) Each Sub-Servicer shall be 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.

                  (c) As part of its servicing activities hereunder, the Master
Servicer and the Special Servicer, for the benefit of the Trustee and the
Certificateholders, shall (at no expense to the Trustee, the Certificateholders
or the Trust Fund) monitor the performance and enforce the obligations of each
Sub-Servicer retained by it under the related Sub-Servicing Agreement. Such
enforcement, including, without limitation, the legal prosecution of claims,
termination of Sub-Servicing Agreements in accordance with their respective
terms and the pursuit of other appropriate remedies, shall be in such form and
carried out to such an extent and at such time by the Master Servicer and the
Special Servicer in accordance with the Servicing Standard.

                  (d) In the event the Trustee, its designee or any successor
Master Servicer or Special Servicer assumes the rights and obligations of the
Master Servicer or the Special Servicer under any Sub-Servicing Agreement, the
Master Servicer or the Special Servicer, as the case may be, at its expense
shall, upon request of the Trustee, deliver to the assuming party all documents
and records relating to such Sub-Servicing Agreement and the Mortgage Loans then
being serviced thereunder and an accounting of amounts collected and held on
behalf of it thereunder, and otherwise use reasonable efforts to effect the
orderly and efficient transfer of the Sub-Servicing Agreement to the assuming
party.

                  (e) Notwithstanding any Sub-Servicing Agreement, the Master
Servicer and the Special Servicer each shall remain obligated and liable to the
Trustee and the Certificateholders for the servicing and administration of the
Mortgage Loans and Loan Groups in accordance with the provisions of this
Agreement to the same extent and under the same terms and conditions as if it
alone were servicing and administering the Mortgage Loans and Loan Groups for
which it is responsible.

                  SECTION 3.23  Designation of Special Servicer by the Majority
                                Certificateholder of the Controlling Class.

                  (a) The Majority Certificateholder of the Controlling Class,
may at any time and from time to time replace any existing Special Servicer or
any Special Servicer that has resigned or otherwise ceased to serve as Special
Servicer, including pursuant to Section 7.01. Such Holders shall so designate a
Person to so serve by the delivery to the Trustee of a written notice stating
such designation, subject to Rating Agency Confirmation. The Trustee shall,
promptly after receiving any such notice, so notify the Rating Agencies. The
designated Person shall become the Special Servicer as of the date the Trustee
shall have received: (i) written confirmation from the Rating Agencies stating
that if the designated Person were to serve as Special Servicer hereunder, none
of the then-current ratings of the outstanding Classes of the Certificates would
be qualified (including by placement on "negative credit watch"),

                                      125
<PAGE>

downgraded or withdrawn; (ii) a written acceptance of all obligations of the
Special Servicer under this Agreement, executed by the designated Person; and
(iii) an Opinion of Counsel (at the expense of the Person designated to become
the Special Servicer or the Holders that made the designation) to the effect
that the designation of such Person to serve as Special Servicer is in
compliance with this Section 3.23 and all other applicable provisions of this
Agreement, that upon the execution and delivery of the written acceptance
referred to in the immediately preceding clause (ii), the designated Person
shall be bound by the terms of this Agreement and that this Agreement shall be
enforceable against the designated Person in accordance with its terms. The
existing Special Servicer shall be deemed to have resigned simultaneously with
such designated Person's becoming the Special Servicer hereunder; provided,
however, that (i) the resigning Special Servicer shall continue to be entitled
to receive all amounts accrued or owing to it under this Agreement on or prior
to the effective date of such resignation, whether in respect of Servicing
Advances or otherwise, and (ii) it and its directors, officers, employees and
agents shall continue to be entitled to the benefits of Section 6.03,
notwithstanding any such resignation. Such resigning Special Servicer shall
cooperate with the Trustee, the Master Servicer and the replacement Special
Servicer in effecting the termination of the resigning Special Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer within two Business Days to the replacement Special Servicer for
administration by it of all cash amounts that shall at the time be or should
have been deposited in the REO Account or delivered by the Special Servicer to
the Master Servicer or that are thereafter received with respect to Specially
Serviced Mortgage Loans and REO Properties.

                  (b) The Majority Certificateholder of the Controlling Class
will have no liability to the Trust 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. Each Holder and Certificate Owner
acknowledges and agrees, by its acceptance of its Certificates or an interest
therein, that the Majority Certificateholder of the Controlling Class may have
special relationships and interests that conflict with those of Holders and
Certificate Owners of one or more Classes of Certificates, that the Majority
Certificateholder of the Controlling Class may act solely in the interests of
the Holders and Certificate Owners of the Controlling Class, that the Majority
Certificateholder of the Controlling Class does not have any duties to the
Holders and Certificate Owners of any Class of Certificates other than the
Controlling Class, that the Majority Certificateholder of the Controlling Class
may take actions that favor interests of the Holders and Certificate Owners of
the Controlling Class over the interests of the Holders and Certificate Owners
of one or more other Classes of Certificates, and that the Majority
Certificateholder of the Controlling Class shall have no liability whatsoever
for having so acted, and no Certificateholder may take any action whatsoever
against the Majority Certificateholder of the Controlling Class or any director,
officer, employee, agent or principal thereof for having so acted.

                  (c) Notwithstanding the foregoing, if the Controlling Class
consists of Book-Entry Certificates, then the rights of the Holders of the
Controlling Class set forth above in this Section 3.23 may be exercised directly
by the relevant Certificate Owners, provided that the identity of such
Certificate Owners has been confirmed to the Trustee to its reasonable
satisfaction.

                  SECTION 3.24  Lock-Box Accounts and Servicing Accounts.

                  (a) The Master Servicer shall administer each Lock-Box
Account, Cash Collateral Account and Servicing Account in accordance with the
related Mortgage Loan or Loan Group, Cash Collateral Account Agreement or
Lock-Box Agreement, if any.

                  (b) For any Mortgage Loan or Loan Group that provides that a
Lock-Box Account or Cash Collateral Account will be established upon the
occurrence of certain events specified in such Mortgage Loan or Loan Group, the
Master Servicer (or, with respect to any Specially Serviced Loan, the Special
Servicer) shall use reasonable efforts to establish or cause to be established
such Lock-Box Account upon the occurrence of such events unless the Master
Servicer (or the Special Servicer, as applicable) determines, in accordance with
the Servicing Standards, that such Lock-Box Account should not be established.
Notwithstanding the foregoing, the Master Servicer (or the Special Servicer, as
applicable) shall use reasonable efforts to establish or cause to be established
a Lock-Box Account for each ARD Loan no later than its Anticipated Repayment
Date.

                  SECTION 3.25  Representations and Warranties of the Master
                                Servicer and the Special Servicer.

                  GMACCM, in its capacity as both Master Servicer and Special
Servicer hereunder hereby represents and warrants to the Trustee, for its own
benefit and the benefit of the Certificateholders, the Fiscal Agent and to the
Depositor, as of the Closing Date, that:

                          (i) GMACCM is a corporation, duly organized, validly
             existing and in good standing under the laws of the State of
             California, and GMACCM is in compliance with the laws of each State
             in which any Mortgaged Property is located to the extent necessary
             to perform its obligations under this Agreement.

                          (ii) The execution and delivery of this Agreement by
             GMACCM, and the performance and compliance with the terms of this
             Agreement by GMACCM, will not violate GMACCM's organizational
             documents 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) GMACCM 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 GMACCM, enforceable against
             GMACCM in accordance with the terms hereof, subject to (A)
             applicable bankruptcy, insolvency, reorganization, moratorium and
             other laws affecting the enforcement of creditors' rights
             generally, and (B) general principles of equity, regardless of
             whether such enforcement is considered in a proceeding in equity or
             at law.

<PAGE>

                          (v) GMACCM 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, 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 GMACCM's good faith and
             reasonable judgment, is likely to affect materially and adversely
             either the ability of GMACCM to perform its obligations under this
             Agreement or the financial condition of GMACCM.

                          (vi) No litigation is pending or, to the best of
             GMACCM's knowledge, threatened against GMACCM the outcome of which,
             in GMACCM's good faith and reasonable judgment, could reasonably be
             expected to prohibit GMACCM from entering into this Agreement or
             materially and adversely affect the ability of GMACCM to perform
             its obligations under this Agreement.

                          (vii) GMACCM has errors and omissions insurance
             coverage which is in full force and effect and complies with the
             requirements of Section 3.07 hereof.

                          (viii) No consent, approval, authorization or order,
             registration or filing with or notice to, any governmental
             authority or court is required, under federal or state law, for the
             execution, delivery and performance of or compliance by GMACCM with
             this Agreement, or the consummation by GMACCM of any transaction
             contemplated hereby, other than (1) such consents, approvals,
             authorizations, qualifications, registrations, filings, or notices
             as have been obtained or made and (2) where the lack of such
             consent, approval, authorization, qualification, registration,
             filing or notice would not have a material adverse effect on the
             performance by GMACCM under this Agreement.

                         PAYMENTS TO CERTIFICATEHOLDERS
                               AND RELATED MATTERS

                  SECTION 4.01  Distributions.

                  (a) On each Distribution Date, the Trustee shall be deemed to

             for all prior Distribution Dates;

                          (ii) to pay principal to REMIC II in respect of the
             various REMIC I Regular Interests, up to an amount equal to, and
             pro rata in accordance with, in the case of each such REMIC I
             Regular Interest for such Distribution Date, the excess, if any, of
             the Uncertificated Principal Balance of such REMIC I Regular
             Interest outstanding

             immediately prior to such Distribution Date, over the Stated
             Principal Balance of the related Mortgage Loan, Companion Loan, REO
             Loan or, if applicable, Replacement Mortgage Loan(s), as the case
             may be, that will be outstanding immediately following such
             Distribution Date; and

                          (iii) to reimburse REMIC II for any Realized Losses
             and Additional Trust Fund Expenses previously deemed allocated to
             the various REMIC I Regular Interests, up to an amount equal to,
             and pro rata in accordance with, the Loss Reimbursement Amount for
             each such REMIC I Regular Interest immediately prior to such
             Distribution Date.

                  On each Distribution Date, the Trustee shall be deemed to

(i), that portion, if any, of the Available Certificate Distribution Amount and
Available Class S Distribution Amount for such date that has not otherwise been
deemed paid to REMIC II in respect of the REMIC I Regular Interests pursuant to
the foregoing provisions of this Section 4.01(a) (such portion, the "Class R-I

                  On each Distribution Date, the Trustee shall be deemed to

amounts relating to Prepayment Premiums) deemed paid to REMIC II in respect of
the REMIC I Regular Interests pursuant to this Section 4.01(a) on any

apply the REMIC II Distribution Amount (other than any amounts withdrawn from
the Excess Liquidation Proceeds Reserve Account) for such date for the following

                          (i) to pay interest to REMIC III in respect of all
             REMIC II Regular Interests up to an amount equal to all
             Uncertificated Distributable Interest in respect of such REMIC II
             Regular Interests for such Distribution Date and, to the extent not
             previously deemed paid, for all prior Distribution Dates with such
             payments allocated among the REMIC II Regular Interests such that
             remaining amounts, if any, of unpaid

             interest on each such REMIC II Regular Interest will equate to the
             remaining unpaid accrued interest on the corresponding Class of
             Principal Balance Certificates or Class X Component outstanding
             after all subsequent adjustments made on such Distribution Date
             under Section 4.01(c) below;

             REMIC II Regular Interests apportioned as payment of Uncertificated
             Principal Balance among REMIC II Regular Interests such that the
             remaining Uncertificated Principal Balance of each such class will
             equal the then outstanding Class Principal Balance of the
             corresponding Principal Balance Certificate after all subsequent
             adjustments made on such Distribution Date under Sections 4.01(c)
             and (i) below (other than payments thereunder in reimbursement of
             any Realized Losses and Additional Trust Fund Expenses); and

                          (iii) to reimburse REMIC III for any Realized Losses
             and Additional Trust Fund Expenses previously deemed allocated to
             REMIC II Regular Interests, apportioned among the REMIC II Regular

             corresponding Classes of Principal Balance Certificates on such
             Distribution Date under Sections 4.01(c) and (i) below.

                  On each Distribution Date, the Trustee shall be deemed to
apply any amounts withdrawn from the Excess Liquidation Proceeds Reserve Account
for such Distribution Date to reimburse REMIC III for any Realized Losses and
Additional Trust Fund Expenses previously deemed allocated to REMIC II Regular
Interests and unreimbursed pursuant to Section 4.01(b)(iii), consistent with the
reimbursement payments made on the corresponding Classes of Principal Balance
Certificates on such Distribution Date under Sections 4.01(c) and (i) below.

                  On each Distribution Date, the Trustee shall pay to the
Holders of the Class R-II Certificates, in accordance with Sections 4.01(c) and
(i), that portion, if any, of the REMIC II Distribution Amount for such date
that has not otherwise been deemed paid to REMIC III in respect of the REMIC II
Regular Interests pursuant to the foregoing provisions of this Section 4.01(b)
(such portion, the "Class R-II Distribution Amount" for such Distribution Date).

                  On each Distribution Date, the Trustee shall be deemed to
apply all amounts relating to Prepayment Premiums then on deposit in the
applicable Distribution Account and received during or prior to the related
Collection Period, to pay additional interest to REMIC III in respect of REMIC
II Regular Interests allocable among the REMIC II Regular Interests in an amount
with respect to each REMIC II Regular Interest equal to the amount allocable to
the corresponding Class of Principal Balance Certificates and Class X Component
outstanding after all subsequent adjustments made on such Distribution Date
under Sections 4.01(c) and (i) below.

                  (c) On each Distribution Date, following the deemed payments
to REMIC III in respect of the REMIC II Regular Interests on such date pursuant
to Section 4.01(b), the Trustee shall withdraw from the applicable Distribution
Account the Available Certificate Distribution Amount for such Distribution Date
and shall apply such amount for the following purposes and in the following
order of priority:

(xxiii), (xxvi), (xxix), (xxxii), (xxxv) and (xxxviii) above with respect to any
Class of Principal Balance Certificates, will be so made to the Holders thereof,
up to an amount equal to the entire then outstanding Class Principal Balance of
such Class of Certificates. References to "remaining Principal Distribution
Amount" in any of clauses (ii), (v), (viii), (xi), (xiv), (xvii), (xx), (xxiii),
(xxvi), (xxix), (xxxii), (xxxv), (xxxviii) and (xli) above, in connection with
the payments of principal to be made to the Holders of any Class of Principal
Balance Certificates, shall be to the Principal Distribution Amount for such
Distribution Date, net of any payments of principal made in respect thereof to
the Holders of each Class of Principal Balance Certificates that have a higher
Payment Priority.

                  On each Distribution Date, the Trustee shall withdraw any
amounts then on deposit in the applicable Distribution Account that represent
Prepayment Premiums collected

                                      136
<PAGE>

during or prior to the related Collection Period and shall distribute such
amounts, in each case, subject to available funds, as additional interest, as
follows:

                  (i) to the Holders of the Class A, Class B, Class C, Class D,
         Class E and Class F Certificates up to an amount equal to, in the case
         of each such Class, the product of (a) such Prepayment Premiums, (b)
         the applicable Discount Rate Fraction and (c) the Principal Allocation
         Fraction of such Class; and

                  (ii) then, to the Holders of the Class X Certificates.

         All of the foregoing distributions to be made from the applicable
Distribution Account on any Distribution Date with respect to the REMIC III
Certificates shall be deemed made from the payments deemed made to REMIC II in
respect of the REMIC II Regular Interests on such Distribution Date pursuant to
Section 4.01(b).

         On each Distribution Date, the Trustee shall withdraw from the
applicable Distribution Account, as Grantor Trust Assets, any amounts that
represent Excess Interest actually collected on the ARD Loans and any related
REO Loans during the related Collection Period and shall distribute with respect
to their interests in the Grantor Trust, such amounts to the holders of the
Class P Certificates, without regard to whether any such Class is entitled to
distributions of interest or principal on such Distribution Date (whether by
reason of its Class Principal Balance having been reduced to zero, by reason of
it not yet being entitled to distributions of principal, or for any other
reason).

         On each Distribution Date, the Trustee shall withdraw amounts from the
Excess Liquidation Proceeds Reserve Account and shall distribute such amounts in
the following priority:

                  (i) first, to reimburse the Holders of the Principal Balance
         Certificates (other than the Class S Certificates) (in order of
         alphabetical Class designation) up to an amount equal to all Realized
         Losses or Additional Trust Fund Expenses, if any, previously deemed
         allocated to them and unreimbursed after application of the Available
         Certificate Distribution Amount for such Distribution Date;

                  (ii) second, for distribution to the Special Servicer as
         additional servicing compensation, the excess, if any, of (x) the
         balance of the Excess Liquidation Proceeds Reserve Account on such
         Distribution Date over (y) the aggregate Certificate Balance of the
         Principal Balance Certificates as of such Distribution Date; and

                  (iii) third, upon the reduction of the aggregate Certificate
         Balance of the Principal Balance Certificates to zero, to pay any
         amounts remaining on deposit in such account to the Special Servicer as
         additional compensation.

(d) All distributions made with respect to each Class on each Distribution Date
shall be allocated pro rata among the outstanding Certificates in such Class
based on their respective Percentage Interests. Except as otherwise provided in
the last paragraph of Section 4.01(c) or as provided below, all such
distributions with respect to each Class on each Distribution Date shall be made
to the Certificateholders of the respective Class of record at the

                                      137
<PAGE>

close of business on the related Record Date and shall be made by wire transfer
of immediately available funds to the account of any such Certificateholder at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Trustee with wiring instructions no
less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
Distribution Dates) or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. The final
distribution on each Certificate (determined without regard to any possible
future reimbursement of any Realized Loss or Additional Trust Fund Expense
previously allocated to such Certificate) will be made in like manner, but only
upon presentation and surrender of such Certificate at the offices of the
Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution. Any distribution that is to be
made with respect to a Certificate in reimbursement of a Realized Loss or
Additional Trust Fund Expense previously allocated thereto, which reimbursement
is to occur after the date on which such Certificate is surrendered as
contemplated by the preceding sentence, will be made by check mailed to the
address of the Certificateholder that surrendered such Certificate as such
address last appeared in the Certificate Registrar or to any other address of
which the Trustee was subsequently notified in writing.

         (e) 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
Certificate Registrar, the Depositor, the Master Servicer or the Special
Servicer shall have any responsibility therefor except as otherwise provided by
this Agreement or applicable law.

         (f) The rights of the Certificateholders to receive distributions from
the proceeds of the Trust Fund in respect of their Certificates, and all rights
and interests of the Certificateholders in and to such distributions, shall be
as set forth in this Agreement. Neither the Holders of any Class of Certificates
nor any party hereto 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. Distributions in reimbursement of Realized
Losses and Additional Trust Fund Expenses previously allocated to a Class of
Certificates shall not constitute distributions of principal and shall not
result in a reduction of the related Class Principal Balance.

         (g) Except as otherwise provided in Section 9.01, whenever the Trustee
expects that the final distribution with respect to any Class of Certificates
(determined without regard to any possible future reimbursement of any Realized
Loss or Additional Trust Fund Expense previously allocated to such Class of
Certificates) will be made on the next Distribution Date, the Trustee shall, as
soon as practicable in the month in which such Distribution Date occurs, mail to
each Holder of such Class of Certificates as of the date of mailing a notice to
the effect that:

                                      138
<PAGE>

                  (i) the Trustee 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 offices of the Certificate Registrar or such other location therein
         specified, and

                  (ii) no interest shall accrue on such Certificates from and
         after the applicable Interest Accrual Period for such Distribution
         Date.

         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
uninvested in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(g) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee 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 Trustee, directly or through an agent, shall take such steps
to contact the remaining non-tendering Certificateholders concerning the
surrender of their Certificates as it shall deem appropriate. The costs and
expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any Certificateholder on any
amount held in trust hereunder by the Trustee as a result of such
Certificateholder's failure to surrender its Certificate(s) for final payment
thereof in accordance with this Section 4.01(g). If all of the Certificates
shall not have been surrendered for cancellation by the second anniversary of
the delivery of the second notice, the Trustee shall distribute all unclaimed
funds and other assets which remain subject hereto in accordance with applicable
laws.

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

         (i) On each Distribution Date, for distribution in respect of each
class of Class S Certificates, the Trustee shall withdraw from the applicable
Companion Loan Distribution Account the Available Class S Distribution Amount
deposited in respect of such class of Class S Certificates for such Distribution
Date and shall apply such amount for the following purposes and in the following
order of priority:

                  (i) to pay interest to the Holders of such Class S
         Certificates, in an amount equal to all Distributable Certificate
         Interest in respect of each such Class S

                                      139
<PAGE>

         Certificates for such Distribution Date and, to the extent not
         previously paid, for all prior Distribution Dates;

                  (ii) to pay principal to the Holders of such Class S
         Certificates up to an amount equal to the lesser of (1) the then
         outstanding Class Principal Balance of such Class S Certificates and
         (2) the Class S Principal Distribution Amount for such class;

                  (iii) to reimburse the Holders of such Class S Certificates,
         up to an amount equal to all Realized Losses and Additional Trust Fund
         Expenses, if any, previously deemed allocated to such Class S
         Certificates and for which no reimbursement has previously been paid;
         and

                  (iv) to pay to Holders of the Class R-III Certificates, the
         balance, if any, of the Available Class S Distribution Amount for such
         Distribution Date;

provided that, on the Final Distribution Date, the payments of principal to be
made pursuant to clause (ii) above with respect to any Class S class of
Principal Balance Certificates, will be so made to the Holders thereof, up to an
amount equal to the entire then outstanding Class Principal Balance of such
Class of Class S Certificates.

         (j) On each Distribution Date, the Trustee shall withdraw any amounts
then on deposit in the applicable Companion Loan Distribution Account that
represent Prepayment Premiums collected during or prior to the related
Collection Period and shall distribute such amounts, in each case, subject to
available funds, as additional interest, to the holders of the related class of
Class S Certificateholders.

         (k) All the foregoing distributions to be made under (i) and (j) with
respect to the Class S Certificates shall be deemed made from the payment deemed
made to REMIC II in respect of the REMIC II Regular Interest on such
Distribution Date pursuant to Section 4.01(b).

instruct the Trustee at any time not to require the use of a password or the
receipt of a certification. At the direction of the Depositor, the Trustee shall
remove any or all of such restrictions and make any or all of such information
available to any person. The Trustee makes no representations or warranties as
to the accuracy or completeness of such information and assumes no
responsibility therefor. In addition, the Trustee may disclaim responsibility
for any information distributed by the Trustee for which it is not the original
source. In connection with providing access to the Trustee's internet website,
the Trustee may require registration and acceptance of a disclaimer. The Trustee
shall not be liable for the dissemination of information in accordance with this
Agreement. The Trustee may provide such information through means other than

such alternative means and (ii) Certificateholders shall have received notice of
such alternative means. The provisions in this Section shall not limit the
Master Servicer's ability to make accessible certain information regarding the
Mortgage Loans and Companion Loans at a website maintained by the Master
Servicer.

                  Within a reasonable period of time after the end of each

of the description of Distribution Date Statements above aggregated for such
calendar year or applicable portion thereof during which such person was a
Certificateholder, together with such other information as the Trustee
determines to be necessary to enable Certificateholders to prepare their tax
returns for such calendar year. Such obligation of the

                                      143
<PAGE>

Trustee shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Trustee pursuant to any
requirements of the Code as from time to time are in force.

shall furnish to the Holders of the Residual Certificates the Form 1066 and
shall furnish their respective Schedules Q thereto at the times required by the
Code or the Internal Revenue Service, and shall provide from time to time such
information and computations with respect to the entries on such forms as any
Holder of the Residual Certificates may reasonably request.

                  The specification of information to be furnished by the
Trustee to the Certificateholders in this Section 4.02 (and any other terms of
this Agreement requiring or calling for delivery or reporting of information by
the Trustee to Certificateholders and Certificate Owners) shall not limit the
Trustee in furnishing, and the Trustee is hereby authorized to furnish, to
Certificateholders, Certificate Owners and/or to the public any other

with respect to the Mortgage Loans and Companion Loans, the Mortgaged Properties
or the Trust Fund as may be provided to it by the Depositor, the Master Servicer
or the Special Servicer or gathered by it in any investigation or other manner

the request of the Depositor (except pursuant to clause (E) below), (B) the
Trustee shall be entitled to indicate the source of all information furnished by
it, and the Trustee may affix thereto any disclaimer it deems appropriate in its

appropriate), (C) the Trustee may notify Certificateholders, and Certificate
Owners of the availability of any such information in any manner as it, in its

without the consent of the Depositor, the Trustee may, in its sole discretion,
furnish Additional Information to a Rating Agency in any instance, and to the

determines that the furnishing of such information would assist in the
evaluation of the investment characteristics or valuation of the Certificates or
would be in the best interests of the Certificateholders or is required by
applicable law and, in the case of any Additional Information requested by a
Certificate Owner or Certificateholder, such Certificate Owner or
Certificateholder has delivered an executed certificate in the form of Exhibit K
hereto and (F) the Trustee shall be entitled to distribute or make available
such Additional Information in accordance with such reasonable rules and
procedures as it may deem necessary or appropriate (which may include the
requirement that an agreement that provides such information shall be used
solely for purposes of evaluating the investment characteristics or valuation of
the Certificates be executed by the recipient, if and to the extent the Trustee
deems the same to be necessary or appropriate). Nothing herein shall be
construed to impose upon the Trustee any obligation or duty to furnish or
distribute any Additional Information to any Person in any instance, and the
Trustee shall neither have any liability for furnishing nor for refraining from
furnishing Additional Information in any instance. The Trustee shall be entitled
(but not required) to request and receive direction from the Depositor as to the
manner of delivery of any such Additional Information, if and to the extent the
Trustee deems necessary or advisable, and

                           (ii) the aggregate amount that is to be transferred
         from the Collection Account to the applicable Distribution Account in

                           (v) the loan number and the unpaid principal balance
         as of the close of business on such Determination Date of each
         Specially Serviced Mortgage Loan and each other Defaulted Mortgage
         Loan; and

                           (vi) such other information on a Mortgage
         Loan-by-Mortgage Loan or Loan Group-by-Loan Group or REO
         Property-by-REO Property basis as the Trustee or the Depositor shall

         Companion Loan, any Mortgage Loans or Companion Loans in default or

                  In addition, the Master Servicer is also required to perform
with respect to each Mortgaged Property and REO Property (except any Mortgaged
Property securing a Credit Lease Loan):

                           (i) Within 30 days after receipt of a quarterly
         operating statement, if any, commencing with the calendar quarter ended

         revenue, expense, and net operating income information substantially in
         accordance with Exhibit I presenting the computation made in accordance
         with the methodology set forth in Exhibit F (but only to the extent the
         related borrower is required by the Mortgage to deliver and does
         deliver, or otherwise agrees to provide and does provide, such
         information) for such Mortgaged Property or REO Property as of the end

         Trustee by electronic means the Operating Statement Analysis upon
         request; and

                                      146
<PAGE>

                           (ii) Within 30 days after receipt by the Master
         Servicer of an annual operating statement, an NOI adjustment analysis
         containing substantially the content set forth in Exhibit I (the "NOI
         Adjustment Worksheet") (but only to the extent the related borrower is
         required by the Mortgage to deliver and does deliver, or otherwise
         agrees to provide and does provide, such information), presenting the
         computation made in accordance with the methodology described in
         Exhibit F to "normalize" the full year net operating income and debt
         service coverage numbers used by the Master Servicer in preparing the
         Comparative Financial Status Report above. The Master Servicer will
         deliver to the Trustee by electronic means the "NOI Adjustment
         Worksheet" upon request.

Upon request, the Trustee shall deliver or shall cause to be delivered to each
Certificateholder, to each party hereto, to any Underwriter, to the Rating
Agencies, and to each Person that provides the Trustee with an Investor
Certification a copy of the Operating Statement Analysis and NOI Adjustment
Worksheet most recently performed by the Master Servicer with respect to any
Mortgage Loan or Companion Loan and delivered to the Trustee.

                  Not later than the first day of the calendar month following
each Master Servicer Remittance Date, the Master Servicer shall forward to the
Trustee a statement, setting forth the status of the Collection Account as of
the close of business on such Master Servicer Remittance Date, stating that all
remittances to the Trustee required by this Agreement to be made by the Master
Servicer have been made (or, in the case of any such required remittance that
has not been made by the Master Servicer, specifying the nature and status
thereof) and showing, for the period from the preceding Master Servicer
Remittance Date (or, in the case of the first Master Servicer Remittance Date,
from the Cut-off Date) to such Master Servicer Remittance Date, the aggregate of
deposits into and withdrawals from the Collection Account for each category of
deposit specified in Section 3.04(a) and each category of withdrawal specified

reasonable request of the Trustee, any and all additional information relating
to the Mortgage Pool and the Companion Loans in the possession of the Master
Servicer (which information shall be based upon reports delivered to the Master
Servicer by the Special Servicer with respect to Specially Serviced Mortgage
Loans and REO Properties).

                  The Master Servicer, on the first Business Day following each
Determination Date, shall forward to the Special Servicer all information
collected by the Master Servicer which the Special Servicer is required to
include in the reports delivered by the Special Servicer pursuant to Section
4.02(c) below. Further, the Master Servicer shall cooperate with the Special
Servicer and provide the Special Servicer with the information in the possession
of the Master Servicer reasonably requested by the Special Servicer, in writing,
to the extent required to allow the Special Servicer to perform its obligations
under this Agreement with respect to those Mortgage Loans and Companion Loans
serviced by the Master Servicer.

                  The obligation of the Master Servicer to deliver the reports
required to be delivered by it pursuant to this subsection is subject to the
Master Servicer having received from the Special Servicer in a timely manner the
related reports and information necessary or required to enable the Master
Servicer to prepare and deliver such reports. The Master Servicer shall not be
responsible for the accuracy or content of any report, document or information
furnished by

                                      147
<PAGE>

the Special Servicer to the Master Servicer pursuant to this Agreement and
accepted by the Master Servicer in good faith pursuant to this Agreement.

                  (c) On the second Business Day after each Determination Date,
the Special Servicer shall forward to the Master Servicer, for each Specially
Serviced Mortgage Loan and REO Property, reports containing all information the
Master Servicer will be required to include in the other reports that the Master
Servicer is obligated to deliver to the Trustee pursuant to Section 4.02(b), to
the extent such information relates to any Specially Serviced Mortgage Loan or
any REO Property. The Special Servicer shall also deliver to the Trustee, upon
the reasonable written request of the Trustee, any and all additional
information in the possession of the Special Servicer relating to the Specially
Serviced Mortgage Loans and the REO Properties.

                  The Special Servicer shall cooperate with the Master Servicer
and provide the Master Servicer with the information in the possession of the
Special Servicer reasonably requested by the Master Servicer, in writing, to the
extent required to allow the Master Servicer to perform its obligations under
this Agreement with respect to the Specially Serviced Mortgage Loans and REO
Properties. Additional information regarding the Specially Serviced Mortgage
Loans and REO Properties, including, without limitation, any financial or
occupancy information (including lease summaries) provided to the Special
Servicer by the Mortgagors or otherwise obtained, shall be delivered to the
Master Servicer, within ten days of receipt.

                  (d) The Master Servicer and the Special Servicer may make
available to Certificate Owners who have certified to the Master Servicer their
beneficial ownership of any Certificate, or prospective Certificate Owners who
provide appropriate confirmation that they are prospective Certificate Owners
who intend to keep any information confidential, copies of any reports or files
prepared by the Servicer pursuant to this Agreement.

                  (e) Each of the Master Servicer and Special Servicer may make
information concerning the Mortgage Loans and Companion Loans available on any
website that it has established.

                  SECTION 4.03 Delinquency Advances.

                  (a) On each Delinquency Advance Date, the Master Servicer
shall either (i) deposit into the Collection Account from its own funds an
amount equal to the aggregate amount of Delinquency Advances, if any, to be made
in respect of the related Distribution Date, (ii) apply amounts held in the
Collection Account for future distribution to Certificateholders in subsequent
months in discharge of any such obligation to make Delinquency Advances, or
(iii) make Delinquency Advances in the form of any combination of (i) and (ii)
aggregating the total amount of Delinquency Advances to be made; provided that,
if Late Collections (net of related Workout Fees) of the delinquent Monthly
Payments for which Delinquency Advances are to be made for the related
Distribution Date, are on deposit in the Collection Account and available to
make such Advances, the Master Servicer shall utilize such Late Collections to
make such Advances pursuant to clause (ii) above. Any amounts held in the
Collection Account for future distribution and so used to make Delinquency
Advances 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 the next succeeding Determination Date (to the extent not previously

                                      148
<PAGE>

replaced through the deposit of Late Collections of the delinquent principal and
interest in respect of which such Delinquency Advances were made). If, as of
3:00 p.m., New York City time, on any Master Servicer Remittance Date, the
Trustee shall not have received any Delinquency Advance required to be made by
the Master Servicer pursuant to this Section 4.03(a) (and the Master Servicer
shall not have delivered to the Trustee the requisite Officer's Certificate and
documentation related to a determination of nonrecoverability of a Delinquency
Advance), then the Trustee shall provide notice of such failure to a Servicing
Officer of the Master Servicer by facsimile transmission sent to telecopy no.
(215) 328-0173 (or such alternative number provided by the Master Servicer to
the Trustee in writing) and by telephone at telephone no. (215) 328-1784
(Attention: Master Servicing Manager) (or such alternative number provided by
the Master Servicer to the Trustee in writing) as soon as possible, but in any
event before 5:00 p.m., New York City time, on such day. If after such notice
the Trustee does not receive the full amount of such Delinquency Advances by
11:00 a.m., New York City time, on the Business Day immediately following such
Master Servicer Remittance Date, then the Trustee shall make the portion of such
Delinquency Advances that was required to be, but was not, made by the Master
Servicer pursuant to this Section 4.03(a). If the Trustee fails to make a
Delinquency Advance required to be made by it hereunder, the Fiscal Agent shall
make such advance no later than 1:00 p.m. New York City time on the Business Day
immediately following such Master Servicer Remittance Date. The making of such
Advance by the Fiscal Agent shall cure the failure by the Trustee to make such
Advance.

                  (b) The aggregate amount of Delinquency Advances to be made by
the Master Servicer in respect of the Mortgage Loans and any MacArthur Companion
Loan (including, without limitation, Assumed Monthly Payments for Balloon
Mortgage Loans delinquent as to their respective Balloon Payments) and any REO
Loans for any Distribution Date shall equal, subject to subsection (c) below,
the aggregate of all Monthly Payments (other than Balloon Payments) and any
Assumed Monthly Payments, in each case net of related Workout Fees payable with
respect to such Mortgage Loan or MacArthur Companion Loan hereunder, that were
due or deemed due, as the case may be, in respect thereof on their respective
Due Dates during the same month as such Distribution Date and that were not paid
by or on behalf of the related Mortgagors or otherwise collected as of the close
of business on the later of the related Due Date or the last day of the related
Collection Period (it being understood and agreed that none of the Master
Servicer, the Trustee or the Fiscal Agent shall in any event be obligated
hereunder to make a Delinquency Advance with respect to (i) any Companion Loan
(other than a MacArthur Companion Loan) or (ii) after purchase of any Mortgage
Loan pursuant to the Intercreditor Agreement, such Mortgage Loan).
Notwithstanding the foregoing, (A) if an Appraisal Reduction Amount exists with
respect to any Mortgage Loan that is a Required Appraisal Loan, then, in the
event of subsequent delinquencies thereon, the interest portion of the
Delinquency Advance in respect of such Required Appraisal Loan for the related
Distribution Date shall be reduced (it being herein acknowledged that there
shall be no reduction in the principal portion of such Delinquency Advance) by
the product of (i) the amount of the interest portion of such Delinquency
Advance for such Required Appraisal Loan for such Distribution Date without
regard to this proviso, multiplied by (ii) a fraction, expressed as a
percentage, the numerator of which is equal to (x) in the case of any Mortgage
Loan, the Appraisal Reduction Amount and (y) in the case of any Loan Group, the
excess, if any, of the Appraisal Reduction Amount, over the Stated Principal
Balance of the related Companion Loan and the denominator of which is equal to
the Stated Principal Balance of the Mortgage Loan and any related

                                      149
<PAGE>

Companion Loans for such Required Appraisal Loan immediately prior to such
Distribution Date or (B) if an Appraisal Reduction Amount exists with respect to
the Companion Loans (taken together) that are part of the MacArthur Loan Group
after it has become a Required Appraisal Loan, then, in the event of subsequent
delinquencies thereon, the interest portion of the Delinquency Advance in
respect of related Companion Loans (taken together) for the related Distribution
Date shall be reduced (it being herein acknowledged that there shall be no
reduction in the principal portion of such Delinquency Advance) by the product
of (i) the amount of the interest portion of such Delinquency Advance for such
related Companion Loans (taken together) for such Distribution Date without
regard to this proviso, multiplied by (ii) a fraction, expressed as a
percentage, the numerator of which is equal to the Appraisal Reduction Amount
and the denominator of which is equal to the Stated Principal Balance of such
Companion Loans (taken together) immediately prior to such Distribution Date.

         (c) Notwithstanding anything herein to the contrary, no Delinquency
Advance shall be required to be made hereunder if such Delinquency Advance
would, if made, constitute a Nonrecoverable Delinquency Advance. In addition,
Nonrecoverable Delinquency Advances shall be reimbursable pursuant to Section
3.05(a) out of general collections on the Mortgage Loans and REO Properties on
deposit in the Collection Account. The determination by the Master Servicer or,
if applicable, the Trustee or the Fiscal Agent, that it has made a
Nonrecoverable Delinquency Advance or that any proposed Delinquency Advance, if
made, would constitute a Nonrecoverable Delinquency Advance, shall be evidenced
by an Officer's Certificate delivered promptly (and, in any event, in the case
of a proposed Delinquency Advance to be made by the Master Servicer, no less
than two Business Days prior to the related Delinquency Advance Date) by the
Master Servicer to the Trustee (or, if applicable, retained thereby) and the
Depositor, setting forth the basis for such determination, together with (if
such determination is prior to the liquidation of the related Mortgage Loan,
Loan Group or REO Property) a copy of an Appraisal of the related Mortgaged
Property or REO Property, as the case may be, which shall have been performed
within the twelve months preceding such determination, and further accompanied
by any other information that the Master Servicer or the Special Servicer may
have obtained and that supports such determination. If such an Appraisal shall
not have been required and performed pursuant to the terms of this Agreement,
the Master Servicer, the Special Servicer, the Trustee or the Fiscal Agent, as
the case may be, may, subject to its reasonable and good faith determination
that such Appraisal will demonstrate the nonrecoverability of the related
Advance, obtain an Appraisal for such purpose at the expense of the Trust Fund.
The Trustee and the Fiscal Agent shall be entitled to rely on any determination
of nonrecoverability that may have been made by the Master Servicer or the
Special Servicer with respect to a particular Delinquency Advance, and the
Master Servicer shall be entitled to rely on any determination of
nonrecoverability that may have been made by the Special Servicer with respect
to a particular Delinquency Advance.

         (d) The Master Servicer, the Trustee and the Fiscal Agent shall each be
entitled to receive interest at the Reimbursement Rate in effect from time to
time, accrued on the amount of each Delinquency Advance made thereby (out of its
own funds) for so long as such Delinquency Advance is outstanding (or, if any
Delinquency Advance is required to be made in respect of a delinquent Monthly
Payment on any Mortgage Loan or any MacArthur Companion Loan prior to the end of
the grace period for such Monthly Payment, for so long as such Delinquency
Advance is outstanding following the end of such grace period), payable first,
out

                                      150
<PAGE>

of Penalty Charges received on the Mortgage Loan or any MacArthur Companion
Loan or REO Loan as to which such Delinquency Advance was made and, then, once
such Delinquency Advance has been reimbursed, out of general collections on the
Mortgage Loans or the applicable MacArthur Companion Loan and REO Properties
pursuant to Section 3.05(a) other than any Delinquency Advance made on any
MacArthur Companion Loan.

         (e) Notwithstanding the above, none of the Master Servicer, Trustee or
Fiscal Agent will be required to make any Delinquency Advances on any Companion
Loan except for a MacArthur Companion Loan. Further, in making a determination
regarding whether any Delinquency Advance on a MacArthur Companion Loan is a
Nonrecoverable Delinquency Advance, the party making such determination shall
make such determination based solely upon the ultimate recovery of amounts
related to such Companion Loan.

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

         (a) On each Distribution Date, following the deemed distributions to be
made in respect of the REMIC I Regular Interests pursuant to Section 4.01(a),
the Uncertificated Principal Balance of each REMIC I Regular Interest (after
taking account of such deemed distributions) shall be reduced to equal the
Stated Principal Balance of the related Mortgage Loan, Companion Loan or REO
Loan or, if applicable, Replacement Mortgage Loan(s), as the case may be, that
will be outstanding immediately following such Distribution Date. Such
reductions shall be deemed to be an allocation of Realized Losses and Additional
Trust Fund Expenses.

         (b) On each Distribution Date, following the payments deemed to be made
to REMIC III in respect of the REMIC II Regular Interests on such date pursuant
to Section 4.01(b), the Trustee shall determine the amount, if any, by which (i)
the then aggregate Uncertificated Principal Balance of REMIC II Regular
Interests LA-1, LA-2, LB, LC, LD, LE, LF, LG, LH, LJ, LK, LL, LM, LN, LO, LS-AM,
LS-MAC-1, LS-MAC-2, LS-MAC-3, and LS-MAC-4 exceeds (ii) an amount equal to the
aggregate Stated Principal Balance that will be outstanding immediately
following such Distribution Date. If such excess does exist, then the respective
Uncertificated Principal Balances of such REMIC II Regular Interests shall be
reduced such that the Uncertificated Principal Balance of each REMIC II Regular
Interest corresponds with the Certificate Principal Balance of the corresponding
Class of Principal Balance Certificates outstanding after the subsequent
adjustments made on such Distribution Date under Section 4.04(c) below.

         (c) On each Distribution Date, following all distributions to be made
on such date pursuant to Section 4.01, the Trustee shall allocate first to the
applicable class of Class S Certificates until the remaining Certificate
Principal Balance thereof has been reduced to zero, the aggregate of all
Realized Losses and Additional Trust Fund Expenses that were incurred with
respect to the related Companion Loan at any time following the Cut-off Date
through the end of the related Collection Period and in any event that were not
previously allocated pursuant to this Section 4.04 on any prior Distribution
Date, but only to the extent that (i) the Certificate Principal Balance of such
Class S Certificates as of such Distribution Date (after taking into account all
of the distributions made on such Distribution Date pursuant to Section 4.01),

                                      151
<PAGE>

exceeds (ii) the aggregate Stated Principal Balance of the related Companion
Loan that will be outstanding immediately following such Distribution Date.
Realized Losses and Additional Trust Fund Expenses shall be allocated to the
Class S-MAC-4, Class S-MAC-3, Class S-MAC-2 and Class S-MAC-1 in that order to
the extent of the Certificate Principal Balance of each. On each Distribution
Date, following the distributions to be made to the Certificateholders on such
date pursuant to Section 4.01(c), the Trustee shall determine the amount, if
any, by which (i) the then aggregate Certificate Principal Balance of the
Principal Balance Certificates (after giving effect to the reduction in the
Certificate Principal Balance of any Class S Certificate on such Distribution
Date), exceeds (ii) the aggregate Stated Principal Balance of the Mortgage Loans
that will be outstanding immediately following such Distribution Date. If such
excess does exist, then the Class Principal Balances of the Class P, Class O,
Class N, Class M, Class L, Class K, Class J, Class H, Class G, Class F, Class E,
Class D, Class C and Class B Certificates shall be reduced sequentially, in that
order, in each case, until the first to occur of such excess being reduced to
zero or the related Class Principal Balance being reduced to zero. If, after the
foregoing reductions, the amount described in clause (i) of the second preceding
sentence still exceeds the amount described in clause (ii) of the second
preceding sentence, then the respective Class Principal Balances of the Class
A-1 and Class A-2 Certificates shall be reduced, pro rata in accordance with the
relative sizes of the then outstanding Class Principal Balances of such Classes
of Certificates, until the first to occur of such excess being reduced to zero
or each such Class Principal Balance being reduced to zero. Such reductions in
the Class Principal Balances of the respective Classes of Principal Balance
Certificates shall be deemed to be allocations of Realized Losses and Additional
Trust Fund Expenses.

                                THE CERTIFICATES

         SECTION 5.01      The Certificates.

         (a) The Certificates will be substantially in the respective forms
annexed hereto as Exhibits A-1 through A-24. The Certificates will be issuable
in registered form only; provided, however, that in accordance with Section 5.03
beneficial ownership interests in the Certificates, other than the Residual
Certificates shall initially be held and transferred through the book-entry
facilities of the Depository. The Residual Certificates will be issued as
Definitive Certificates. The REMIC III Regular Certificates will be issuable in
denominations corresponding to initial Certificate Principal Balances or
Certificate Notional Amounts, as the case may be, as of the Closing Date of not
less than $25,000 in the case of the Class A-1, Class A-2, Class B, Class C and
Class D Certificates, $100,000 in the case of the Class E, Class F, Class G,
Class H, Class J, Class K, Class L, Class M, Class N, Class O, Class P and Class
S-AM, Class S-MAC-1, Class S-MAC-2, Class S-MAC-3 and Class S-MAC-4
Certificates, and $1,000,000 in the case of the Class X Certificates, and in
each such case in any whole dollar denomination in excess thereof; provided,
however, that a single Certificate of each Class thereof may be issued in a
different denomination. The Residual Certificates will be issuable only in
denominations representing Percentage Interests of not less than 20% in the
related Class.

                                      152

         (b) The Certificates shall be executed by manual or facsimile signature
on behalf of the Trustee in its capacity as trustee hereunder by an authorized
officer. Certificates bearing the manual or facsimile signatures of individuals
who were at any time the authorized officers of the Trustee shall be entitled to
all benefits under this Agreement, subject to the following sentence,
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,
however, unless there appears on such Certificate a certificate of
authentication substantially in the form provided for herein executed by the
Certificate Registrar by manual signature, and such certificate of
authentication upon any Certificate 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.

         SECTION 5.02 Registration of Transfer and Exchange of Certificates.

         (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar may
prescribe, the Certificate Registrar shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
The Trustee is hereby initially appointed (and hereby agrees to act in
accordance with the terms hereof) as Certificate Registrar for the purpose of
registering Certificates and transfers and exchanges of Certificates as herein
provided. The Certificate Registrar may appoint, by a written instrument
delivered to the Depositor, the Master Servicer and the Special Servicer, any
other bank or trust company to act as Certificate Registrar under such
conditions as the predecessor Certificate Registrar may prescribe, provided that
the predecessor Certificate Registrar shall not be relieved of any of its duties
or responsibilities hereunder by reason of such appointment. If the Trustee
resigns or is removed in accordance with the terms hereof, the successor trustee
shall immediately succeed to its predecessor's duties as Certificate Registrar.
The Depositor, the Master Servicer and the Special Servicer, shall have the
right to inspect the Certificate Register or to obtain a copy thereof at all
reasonable times, and to rely conclusively upon a certificate of the Certificate
Registrar as to the information set forth in the Certificate Register.

         (b) No transfer of any Non-Registered Certificate shall be made unless
such transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made to a Qualified Institutional Buyer in
accordance with Rule 144A promulgated under the Securities Act in a transaction
that does not require such registration or qualification. If such a transfer is
to be made without registration under the Securities Act, other than a transfer
by the Depositor or an Affiliate thereof, then the Trustee shall require, in
order to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 hereto and a certificate from
such Certificateholder's prospective transferee substantially in the form
attached as Exhibit B-2 hereto.

                                      153

         Notwithstanding the foregoing, transfers of a beneficial interest in
any Class (or portion thereof) of Non-Registered Certificates (other than the
Residual Certificates) in accordance with the rules and procedures of the
Depository applicable to transfers by its respective participants will be
permitted if such transfer is made to a Qualified Institutional Buyer in
accordance with Rule 144A promulgated under the Securities Act.

         None of the Depositor, the Trustee, the Fiscal Agent or the Certificate
Registrar is obligated to register or qualify any Class of Non-Registered
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under this Agreement to permit the transfer of any
Non-Registered Certificate without registration or qualification. Any Holder of
a Non-Registered Certificate desiring to effect such a transfer shall, and does
hereby agree to, indemnify the Depositor, the Trustee, the Fiscal Agent and the
Certificate Registrar 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) (i) No transfer of a Senior Certificate or a Class B, Class C,
Class D, Class E, Class F, Class G, Class S-MAC-1, Class S-MAC-2, Class S-MAC-3
or Class S-MAC-4 Certificate or any interest therein shall be made (A) to any
employee benefit plan or other retirement arrangement, including individual
retirement accounts and annuities, Keogh plans and collective investment funds
and separate accounts in which such plans, accounts or arrangements are
invested, that is subject to ERISA or Section 4975 of the Code (each, a "Plan"),
or (B) to any Person who is directly or indirectly purchasing such Certificate
or interest therein on behalf of, as named fiduciary of, as trustee of, or with
"plan assets" of a Plan, unless: either (A) (1) such Plan qualifies as an
accredited investor as defined in Rule 501(a)(1) of Regulation D of the
Securities Act of 1933, as amended and (2) at the time of such transfer, such
Certificates continue to be rated in one of the top four rating categories by at
least one Rating Agency or (B) such Plan is an "insurance company general
account" (within the meaning of PTCE 95-60 (as defined below)) and the
conditions set forth in Sections I and III of PTCE 95-60 have been satisfied as
of the date of acquisition of such Certificate. Each purchaser or transferee
that is a Plan or is investing on behalf of or with Plan assets of a Plan will
be deemed to have represented that the foregoing conditions have been satisfied.

                  (ii) No transfer of a Residual Certificate or any interest
         therein shall be made (A) to any Plan or (B) to any Person who is
         directly or indirectly purchasing such Certificate or interest therein
         on behalf of, as named fiduciary of, as trustee of, or with "plan
         assets" of a Plan. No transfer of a Class H, Class J, Class K, Class L,
         Class M, Class N, Class O, Class P or Class S-AM Certificate or any
         interest therein shall be made (A) to any Plan or (B) to any Person who
         is directly or indirectly purchasing such Certificate or interest
         therein on behalf of, as named fiduciary of, as trustee of, or with
         "plan assets" of a Plan unless the prospective transferee of any such
         Certificate or any interest therein provides a certification of facts
         to the Depositor, the Master Servicer, the Fiscal Agent and the Trustee
         substantially to the effect that (or, if such Certificate is not in
         certificated form, will be deemed to represent that) the purchase of
         such Certificate by or on behalf of, or with "plan assets" of, any Plan
         is permissible under applicable law, will not constitute or result in
         any non-exempt prohibited transaction under ERISA or Section 4975 of
         the Code, will not subject the Depositor, the Trustee, the Fiscal Agent
         or the Master Servicer to any obligation in addition to those
         undertaken herein, and the

                                      154
<PAGE>

         following conditions are met: (a) the source of funds used to purchase
         such Certificate is an "insurance company general account" (as such
         term is defined in United States Department of Labor Prohibited
         Transaction Class Exemption 95-60 ("PTCE 95-60")) and (b) the
         conditions set forth in Sections I and III of PTCE 95-60 have been
         satisfied as of the date of the acquisition of such Certificates. Any
         purchaser of a Class H, Class J, Class K, Class L, Class M, Class N,
         Class O, Class P or Class S-AM Certificate or any interest therein will
         be deemed to have represented by such purchase that either (a) such
         purchaser is not a Plan and is not purchasing such Certificates by or
         on behalf of, or with "plan assets" of, any Plan or (b) the purchase of
         any such Certificate by or on behalf of, or with "plan assets" of, any
         Plan is permissible under applicable law, will not result in any
         non-exempt prohibited transaction under ERISA or Section 4975 of the
         Code, and will not subject the Depositor, the Trustee, the Fiscal Agent
         or the Master Servicer to any obligation in addition to those
         undertaken herein, and the following conditions are met: (i) the source
         of funds used to purchase such Certificate is an "insurance company
         general account" (as such term is defined in PTCE 95-60) and (ii) the
         conditions set forth in Sections I and III of PTCE 95-60 have been
         satisfied as of the date of the acquisition of such Certificates. The
         Trustee may require that any prospective transferee of a Certificate
         that is held as a Definitive Certificate provide such certifications as
         the Trustee may deem desirable or necessary in order to establish that
         such transferee or the Person in whose name such registration is
         requested is not a Plan or a Person who is directly or indirectly
         purchasing such Certificate on behalf of, as named fiduciary of, as
         trustee of, or with "plan assets" of a Plan or that the conditions of
         an acceptable alternative have been satisfied. The Trustee shall not
         have any responsibility to monitor or restrict the transfer of
         Ownership Interests in any Certificates that are in the form of a
         Book-Entry Certificate.

         (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 Trustee under clause (ii)(A) below to deliver
payments to a Person other than such Person and to have irrevocably authorized
the Trustee under clause (ii)(B) below to negotiate the terms of any mandatory
sale 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 a United
         States Person and shall promptly notify the Trustee 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 Trustee shall require delivery
         to it, and no Transfer of any Residual Certificate shall be registered
         until the Trustee receives, an affidavit and agreement substantially in
         the form attached hereto as Exhibit C-1 (a "Transfer Affidavit and
         Agreement") from the proposed Transferee, in form and substance
         satisfactory to the Trustee, representing and warranting, among other
         things, that such Transferee is a Permitted Transferee, that it is not
         acquiring

                                      155
<PAGE>

         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, that it is a United States Person, and
         that it has reviewed the provisions of this Section 5.02(d) and agrees
         to be bound by them.

                  (C) Notwithstanding the delivery of a Transfer Affidavit and
         Agreement by a proposed Transferee under clause (B) above, if the
         Trustee has actual knowledge that the proposed Transferee is not a
         Permitted Transferee or is not a United States Person, 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 (1) to require a Transfer Affidavit
         and Agreement from any prospective Transferee to whom such Person
         attempts to transfer its Ownership Interest in such Residual
         Certificate and (2) not to transfer its Ownership Interest in such
         Residual Certificate unless it provides to the Trustee a certificate
         substantially in the form attached hereto as Exhibit C-2 stating that,
         among other things, it has no actual knowledge that such prospective
         Transferee is not a Permitted Transferee or is not a United States
         Person.

                  (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 Trustee 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) (A) If any purported Transferee shall become a Holder of
a Residual Certificate in violation of the provisions of this Section 5.02(d) or
if any Holder of a Residual Certificate shall lose its status as a Permitted
Transferee or a United States Person, then the last preceding Holder of such
Residual Certificate that was in compliance with the provisions of this Section
5.02(d) 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. None of the Trustee, the Master Servicer, the Special
Servicer or the Certificate Registrar shall be under any 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), or if any Holder of a Residual Certificate shall lose its
         status as a Permitted Transferee or a United States Person, and to the
         extent that the retroactive restoration of the rights of the

                                      156
<PAGE>

         prior Holder of such Residual Certificate as described in clause
         (ii)(A) above shall be invalid, illegal or unenforceable, then the
         Trustee shall have the right, without notice to the Holder or any prior
         Holder of such Residual Certificate, to sell such Residual Certificate
         to a purchaser selected by the Trustee on such terms as the Trustee may
         choose. Such non-complying Holder shall promptly endorse and deliver
         such Residual Certificate in accordance with the instructions of the
         Trustee. Such purchaser may be the Trustee itself or any Affiliate of
         the Trustee. The proceeds of such sale, net of the commissions (which
         may include commissions payable to the Trustee or its Affiliates),
         expenses and taxes due, if any, will be remitted by the Trustee to such
         non-complying Holder. The terms and conditions of any sale under this
         clause (ii)(B) shall be determined in the sole discretion of the
         Trustee, and the Trustee shall not be liable to any Person having an
         Ownership Interest in a Residual Certificate as a result of its
         exercise of such discretion.

                  (iii) The Trustee 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 not a
Permitted Transferee, 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 not a Permitted Transferee. The
Person holding such Ownership Interest shall be responsible for the reasonable
compensation of the Trustee for providing such information.

                  (iv) The provisions of this Section 5.02(d) set forth prior to
this subsection (iv) may be modified, added to or eliminated, provided that
there shall have been delivered to the Trustee and the Depositor the following:

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

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

                                      157
<PAGE>

                  (e) Subject to the preceding subsections, upon surrender for
         registration of transfer of any Certificate at the offices of the
         Certificate Registrar maintained for such purpose, the Trustee shall
         execute and the Certificate Registrar shall 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 any Holder, its Certificates may be
         exchanged for other Certificates of authorized denominations of the
         same Class of a like aggregate Percentage Interest, upon surrender of
         the Certificates to be exchanged at the offices of the Certificate
         Registrar maintained for such purpose. Whenever any Certificates are so
         surrendered for exchange, the Trustee shall execute and the Certificate
         Registrar shall authenticate and deliver the Certificates which the
         Certificateholder making the exchange is entitled to receive.

                  (g) Every Certificate presented or surrendered for transfer or
         exchange shall (if so required by the Trustee or the Certificate
         Registrar) be duly endorsed by, or be accompanied by a written
         instrument of transfer in the form satisfactory to the Trustee and the
         Certificate Registrar duly executed by, the Holder thereof or his
         attorney duly authorized in writing.

                  (h) No service charge shall be imposed for any transfer or
         exchange of Certificates, but the Trustee or the Certificate Registrar
         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.

                  (i) All Certificates surrendered for transfer and exchange
         shall be physically canceled by the Certificate Registrar, and the
         Certificate Registrar shall hold such canceled Certificates in
         accordance with its standard procedures.

                  (j) Upon request, the Certificate Registrar shall provide the
         Master Servicer, the Special Servicer and the Depositor with an updated
         copy of the Certificate Register on or about January 1 and July 1 of
         each year, commencing January 1, 2001.

                  SECTION 5.03 Book-Entry Certificates.

                  (a) Each Class of Certificates other than Residual
         Certificates shall initially be issued as one or more Certificates
         registered in the name of the Depository or its nominee and, except as
         provided in subsection (c) below, transfer of such Certificates may not
         be registered by the Certificate Registrar unless such transfer is to a
         successor Depository that agrees to hold such Certificates for the
         respective Certificate Owners with Ownership Interests therein. Such
         Certificate Owners shall hold and transfer their respective Ownership
         Interests in and to such Certificates through the book-entry facilities
         of the Depository and, except as provided in subsection (c) below shall
         not be entitled to definitive, fully registered Certificates
         ("Definitive Certificates") in respect of such Ownership Interests. The
         Trustee shall not have any responsibility to monitor or restrict the
         transfer of Ownership Interests in any Book-Entry Certificate. 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

                                      158
<PAGE>

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.

         (b) The Trustee, the Master Servicer, the Special Servicer, the
Depositor and the Certificate Registrar 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 such
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 Trustee 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.

         (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depository is no longer willing or able to
properly discharge its responsibilities with respect to the Book-Entry
Certificates, and (B) the Depositor is unable to locate a qualified successor,
or (ii) the Depositor at its option advises the Trustee and the Certificate
Registrar in writing that it elects to terminate the book-entry system through
the Depository, the Trustee 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 Certificate Registrar of the Book-Entry Certificates by the
Depository, accompanied by registration instructions from the Depository for
registration of transfer and any other documents necessary to satisfy the
requirements of any applicable transfer restrictions, the Trustee shall execute,
and the Certificate Registrar shall authenticate and deliver, the applicable
Definitive Certificates to the Certificate Owners identified in such
instructions. None of the Depositor, the Master Servicer, the Special Servicer,
the Trustee, the Fiscal Agent or the Certificate Registrar shall be liable for
any delay in delivery of such instructions, and each may conclusively rely on,
and shall be protected in relying on, such instructions. Upon the issuance of
Definitive Certificates for purposes of evidencing ownership of the Registered
Certificates held in book-entry form, the registered holders of such Definitive
Certificates shall be recognized as Certificateholders hereunder and,
accordingly, shall be entitled directly to receive payments on, to exercise
Voting Rights with respect to, and to transfer and exchange such Definitive
Certificates.

         SECTION 5.04 Mutilated, Destroyed, Lost or Stolen Certificates.

         If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Trustee and the Certificate Registrar such security or indemnity as may
be required by them to save each of them harmless, then, in the absence of
actual notice to the Trustee or the Certificate Registrar that such Certificate
has been acquired by a bona fide purchaser, the Trustee shall execute, and the
Certificate Registrar shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Certificate,

                                      159
<PAGE>

a new Certificate of the same Class and like Percentage Interest. Upon the
issuance of any new Certificate under this Section, the Trustee and the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) connected therewith. Any replacement Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the applicable REMIC, as if originally issued, whether or not the
lost, stolen or destroyed Certificate shall be found at any time.

         SECTION 5.05 Persons Deemed Owners.

         Prior to due presentation of a Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the person in whose name such Certificate is registered as of the related
Record Date as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 4.01 and for all other purposes whatsoever,
except as and to the extent provided in the definition of "Certificateholder",
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any agent of any of them shall be affected
by notice to the contrary except as provided in Section 5.02(d).

                                   ARTICLE VI

           THE DEPOSITOR, THE MASTER SERVICER AND THE SPECIAL SERVICER

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

         The Depositor, the Master Servicer and the Special Servicer shall be
liable in accordance herewith only to the extent of the respective obligations
specifically imposed upon and undertaken by the Depositor, the Master Servicer
and the Special Servicer herein.

         SECTION 6.02 Merger, Consolidation or Conversion of the Depositor, the
                      Master Servicer and the Special Servicer; Assignment of
                      Rights and Delegation of Duties by the Master Servicer and
                      the Special Servicer.

         (a) Subject to subsection (b) below, the Depositor, the Master Servicer
and the Special Servicer each will keep in full effect its existence, rights and
franchises as a corporation under the laws of the jurisdiction of its
incorporation, and 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
or Companion Loans and to perform its respective duties under this Agreement.

         (b) The Depositor, the Master Servicer and the Special 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, the Master Servicer or the
Special Servicer shall be a party, or any Person succeeding

                                      160
<PAGE>

to the business of the Depositor, the Master Servicer and the Special Servicer,
shall be the successor of the Depositor, the Master Servicer and the Special
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 that (i) such Person is
qualified to service multifamily mortgage loans on behalf of FNMA or FHLMC and
(ii) such merger, consolidation or succession will not result in the downgrade,
qualification or withdrawal of the then-current ratings of the Classes of
Certificates that have been so rated (as evidenced by a letter to such effect
from each Rating Agency).

         (c) Notwithstanding anything else in this Section 6.02 and Section 6.04
to the contrary, the Master Servicer and the Special Servicer may assign all of
its rights and delegate all of its duties and obligations under this Agreement;
provided that the Person accepting such assignment or delegation shall be a
Person that is qualified to service multifamily mortgage loans on behalf of FNMA
or FHLMC, is reasonably satisfactory to the Trustee and the Depositor, is
willing to service the Mortgage Loans and Companion Loans and executes and
delivers to the Depositor and the Trustee an agreement, in form and substance
reasonably satisfactory to the Depositor and the Trustee, which contains an
assumption by such Person of the due and punctual performance and observance of
each covenant and condition to be performed or observed by the Master Servicer
or the Special Servicer, as the case may be, under this Agreement; provided
further that such assignment or delegation will not result in the downgrade,
qualification or withdrawal of the then-current ratings of the Classes of
Certificates that have been rated (as evidenced by a Rating Agency
Confirmation). In the case of any such assignment and delegation, the Master
Servicer or the Special Servicer, as the case may be, shall be released from its
obligations under this Agreement, except that the Master Servicer or the Special
Servicer, as the case may be, shall remain liable for all liabilities and
obligations incurred by it, or arising from its conduct, hereunder prior to the
satisfaction of the conditions to such assignment and delegation set forth in
the preceding sentence. Notwithstanding anything above to the contrary, each of
the Master Servicer and the Special Servicer may, in its sole discretion,
appoint Sub-Servicers in accordance with Section 3.22 hereof and independent
contractors or agents to perform select duties thereof, provided that the Master
Servicer or the Special Servicer shall not be relieved from such duties solely
by virtue of such appointment.

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

         None of the Depositor, the Master Servicer, the Special Servicer or any
of the directors, officers, employees or agents of the Depositor, the Master
Servicer or the Special 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, the Special Servicer or any such Person against
any breach of warranties or representations made herein or 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, the
Special Servicer and any director, officer, employee or agent of the Depositor,
the Master Servicer or the Special Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor,

                                      161
<PAGE>

the Master Servicer and the Special Servicer and any director, officer, employee
or agent of the Depositor, the Master Servicer or the Special Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense incurred in connection with any legal action relating to this Agreement
or the Certificates or any asset of the Trust Fund, other than any loss,
liability or expense specifically required to be borne by such Person pursuant
to the terms hereof, or which constitutes a Servicing Advance (and is otherwise
specifically reimbursable hereunder), or which is incurred by such Person by
reason of such Person's willful misfeasance, bad faith or negligence in the
performance of such Person's duties hereunder or by reason of such Person's
reckless disregard of obligations and duties hereunder. Notwithstanding the
foregoing, in the event of any loss, liability or expense described in the
preceding sentence relates to a Loan Group or related Mortgaged Property, (A)
only the Trust Fund and the related Class S Certificateholder (and not any
unrelated Class S Certificateholder) shall be required to indemnify such Persons
specified in such sentence, and such indemnification shall be made only from
amounts otherwise distributable to such Class S Certificateholder and to the
Trust Fund and (B) no Class S Certificateholder shall have any liability
hereunder with respect to any loss, liability or expense (i) relating solely to
any other Loan Group or Mortgage Loan not a part of such Loan Group or (ii)
relating solely to the issuance, sale, transfer or administration of or
distributions with respect to the Certificates or otherwise solely to the Trust
Fund.

         None of the Depositor, the Master Servicer or the Special Servicer
shall be under any obligation to appear in, prosecute or defend any legal or
administrative action, proceeding, hearing or examination that is not incidental
to its respective duties under this Agreement and which in its opinion may
involve it in any ultimate expense or liability; provided, however, that the
Depositor, the Master Servicer or the Special Servicer may in its discretion
undertake any such action, proceeding, hearing or examination that it may deem
necessary or desirable in respect to this Agreement and the rights and duties of
the parties hereto and the interests of the Certificateholders hereunder. In
such event, the legal expenses and costs of such action, proceeding, hearing or
examination and any liability resulting therefrom shall be expenses, costs and
liabilities of the Trust Fund, and the Depositor, the Master Servicer and the
Special Servicer shall be entitled to be reimbursed therefor out of amounts
attributable to the Mortgage Loans on deposit in the Collection Account as
provided by Section 3.05(a).

         SECTION 6.04 Depositor, Master Servicer and Special Servicer Not to
                      Resign.

         Subject to the provisions of Section 6.02, none of the Depositor, the
Master Servicer or the Special Servicer shall resign from its respective
obligations and duties hereby imposed on it except upon determination that its
duties hereunder are no longer permissible under applicable law. Any such
determination permitting the resignation of the Depositor, the Master Servicer
or the Special Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee. No such resignation by the Master Servicer or
the Special Servicer shall become effective until the Trustee or a successor
servicer shall have assumed the responsibilities and obligations of the Master
Servicer or the Special Servicer, as the case may be, in accordance with Section
7.02.

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

         The Depositor may, but is not obligated to, enforce the obligations of
the Master Servicer and the Special Servicer hereunder and may, but is not
obligated to, perform, or cause a designee to perform, any defaulted obligation
of the Master Servicer or the Special Servicer hereunder or exercise the rights
of the Master Servicer or the Special Servicer hereunder; provided, however,
that neither the Master Servicer nor the Special Servicer shall be relieved of
any of its obligations hereunder 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 or the Special Servicer
and is not obligated to supervise the performance of the Master Servicer or the
Special Servicer under this Agreement or otherwise.

                                  ARTICLE VII

                                     DEFAULT

         deposit into, or to remit to the Trustee for deposit into, the
         applicable Distribution Account any amount required to be so deposited
         or remitted, which failure is not remedied by 11:00 a.m. (New York City
         time) on the relevant Distribution Date; or

                  (ii) any failure by the Special Servicer to deposit into, or
         to remit to the Master Servicer for deposit into, the Collection
         Account any amount required to be so deposited or remitted under this
         Agreement which failure continues unremedied for one Business Day
         following the date on which such deposit or remittance was first
         required to be made; or

                  (iii) any failure by the Master Servicer or the Special
         Servicer to timely make any Servicing Advance required to be made by it
         pursuant to this Agreement which continues unremedied for a period
         ending on the earlier of (A) 15 days following the date such Servicing
         Advance was first required to be made, and (B) either, if applicable,
         (1) in the case of a Servicing Advance relating to the payment of
         insurance premiums, the day on which such insurance coverage terminates
         if such premiums are not paid or (2) in the case of a Servicing Advance
         relating to the payment of real estate taxes, the date of the
         commencement of a foreclosure action with respect to the failure to
         make such payment; or

                  (iv) any failure on the part of the Master Servicer or the
         Special Servicer duly to observe or perform in any material respect any
         other of the covenants or agreements on the part of the Master Servicer
         or the Special Servicer contained in this

                                      163
<PAGE>

         Agreement which continues unremedied for a period of 30 days after the
         date on which written notice of such failure, requiring the same to be
         remedied, shall have been given to the Master Servicer or the Special
         Servicer, as the case may be, by the Trustee or the Depositor, or to
         the Master Servicer or the Special Servicer, as the case may be by the
         Holders of Certificates entitled to not less than 25% of the Voting
         Rights; provided, however, that if such covenant or agreement is
         capable of being cured and the Master Servicer or Special Servicer, as
         applicable, is diligently pursuing such cure, such 30 day period shall
         be extended for an additional 30 days; or

                  (v) any breach on the part of the Master Servicer or the

         Agreement which materially and adversely affects the interests of any
         Class of Certificateholders and which continues unremedied for a period
         of 30 days after the date on which notice of such breach, requiring the
         same to be remedied, shall have been given to the Master Servicer or
         the Special Servicer by the Trustee or the Depositor, or to the Master
         Servicer or the Special Servicer, as the case may be by the Holders of
         Certificates entitled to not less than 25% of the Voting Rights;
         provided, however, if such breach is capable of being cured and the
         Master Servicer or Special Servicer, as applicable, is diligently
         pursuing such cure, such 30 day period shall be extended for an
         additional 30 days; or

                  (vi) a decree or order of a court or agency or supervisory
         authority having jurisdiction in the premises in an involuntary case

         trustee or similar official in any bankruptcy, insolvency, readjustment
         of debt, marshalling of assets and liabilities or similar proceedings,
         or for the winding-up or liquidation of its affairs, shall have been
         entered against the Master Servicer or the Special Servicer and such
         decree or order shall have remained in force undischarged or unstayed
         for a period of 60 days; or

                  (vii) the Master Servicer or the Special Servicer shall
         consent to the appointment of a conservator, receiver, liquidator,
         trustee or similar official in any bankruptcy, insolvency, readjustment
         of debt, marshalling of assets and liabilities or similar proceedings
         of or relating to it or of or relating to all or substantially all of
         its property; or

                  (viii) the Master Servicer or the Special 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 bankruptcy,
         insolvency or reorganization statute, make an assignment for the
         benefit of its creditors, voluntarily suspend payment of its
         obligations, or take any corporate action in furtherance of the
         foregoing;

                  (ix) the Trustee shall have received written notice from Fitch
         that the continuation of the Master Servicer or the Special Servicer in
         such capacity would result in the downgrade, qualification or
         withdrawal of any rating then assigned by such Fitch to any Class of
         Certificates; or

                                      164
<PAGE>

                  (x) a Servicing Officer of the Master Servicer or the Special
         Servicer (as the case may be) receives actual knowledge, that: (i)
         Moody's has qualified, downgraded or withdrawn the rating or ratings on
         one or more Classes of Certificates, or (ii) that Moody's has placed
         one or more Classes of Certificates on "watch status" or "watch status"
         in contemplation of a rating qualification, downgrade or withdrawal
         (and such "watch status" placement shall not have been withdrawn by
         Moody's within 60 days of the date the Servicing Officer of the Master
         Servicer or the Special Servicer (as the case may be) obtained such
         actual knowledge), in the cases of either of clauses (i) or (ii),
         citing servicing concerns with the Master Servicer or the Special
         Servicer (as the case may be) as the sole or material factor in such
         action.

         (b) If any Event of Default with respect to the Master Servicer or the
Special Servicer (in either case for purposes of this Section 7.01(b), the
"Defaulting Party") shall occur and be continuing, then, and in each and every
such case, so long as such 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 the Voting Rights, the Trustee shall
terminate, by notice in writing to the Defaulting Party, with a copy of such
notice to the Depositor (if the termination is effected by the Trustee) or to
the Trustee (if the termination is effected by the Depositor), all of the rights
and obligations of the Defaulting Party under this Agreement and in and to the
Mortgage Loans and Loan Groups and the proceeds thereof (other than any rights
of the Defaulting Party as Certificateholder). From and after the receipt by the
Defaulting Party of such written notice, all authority and power of the
Defaulting Party under this Agreement, whether with respect to the Certificates
(other than as a Holder of any Certificate) or the Mortgage Loans or Loan Groups
or otherwise, shall pass to and be vested in the Trustee pursuant to and under
this Section, and, without limitation, the Trustee is hereby authorized and
empowered to execute and deliver, on behalf of and at the expense of the
Defaulting Party, as attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans or
Loan Groups and related documents, or otherwise. The Master Servicer and the
Special Servicer each agrees that if it is terminated pursuant to this Section
7.01(b), it shall promptly (and in any event no later than ten Business Days
subsequent to its receipt of the notice of termination) provide the Trustee or
any other Successor Master Servicer or Special Servicer with all documents and
records requested by it to enable it to assume the Master Servicer's or Special
Servicer's, as the case may be, functions hereunder, and shall cooperate with
the Trustee or any other Successor Master Servicer or Special Servicer in
effecting the termination of the Master Servicer's or Special Servicer's, as the
case may be, responsibilities and rights hereunder, including, without
limitation, the transfer within two Business Days to the Trustee or any other
Successor Master Servicer or Special Servicer for administration by it of all
cash amounts which shall at the time be or should have been credited by the
Master Servicer or the Special Servicer to the Collection Account, the
applicable Distribution Account, the REO Account or any Servicing Account or
thereafter be received with respect to the Mortgage Loans, Companion Loans or
any REO Property (provided, however, that the Master Servicer and the Special
Servicer each shall continue to be entitled to receive all amounts accrued or
owing to it under this Agreement on or prior to the date of such termination,
whether in respect of Advances made by it or otherwise, and it and its
directors, officers, employees and agents shall continue to be entitled to the
benefits of Section 6.03 notwithstanding any such termination).

         SECTION 7.02 Trustee to Act; Appointment of Successor.

         On and after the time the Master Servicer or the Special Servicer
resigns pursuant to Section 6.04 or receives a notice of termination pursuant to
Section 7.01, the Trustee shall be the successor in all respects to the Master
Servicer or the Special Servicer, as the case may be, in its capacity as such
under this Agreement 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 or the Special
Servicer, as the case may be, by the terms and provisions hereof, including,
without limitation, the Master Servicer's obligation to make Delinquency
Advances; provided that any failure to perform such duties or responsibilities
caused by the Master Servicer's or the Special Servicer's failure to provide
information or monies required by Section 7.01 shall not be considered a default
by the Trustee hereunder. The Trustee shall not be liable for any of the
representations and warranties of the Master Servicer or the Special Servicer or
for any losses incurred by the Master Servicer or the Special Servicer pursuant
to Section 3.06 hereunder nor shall the Trustee be required to purchase any
Mortgage Loan or Loan Group hereunder. As compensation therefor, the Trustee
shall be entitled to the applicable Servicing Fee and Special Servicing Fee and
all funds relating to the Mortgage Loans or Loan Groups which the Master
Servicer or the Special Servicer would have been entitled to charge to the
Collection Account or the applicable Distribution Account if the Master Servicer
or the Special Servicer had continued to act hereunder. Notwithstanding the
above, the Trustee may, if it shall be unwilling to so act, or shall, if it is
unable to so act or if the Holders of Certificates entitled to at least 51% of
the Voting Rights so request in writing to the Trustee or if the Trustee is not
approved as a master servicer or special servicer, as the case may be, by each
Rating Agency, promptly appoint any FNMA or FHLMC-approved mortgage loan
servicing institution that has a net worth of not less than $10,000,000 and is
otherwise acceptable to each Rating Agency (as evidenced by Rating Agency
Confirmation), as the successor to the Master Servicer hereunder or the Special
Servicer, as the case may be, in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master Servicer or the Special
Servicer, as the case may be, hereunder. No appointment of a successor to the
Master Servicer or the Special Servicer, as the case may be, hereunder shall be
effective until the assumption of the successor to the Master Servicer or the
Special Servicer, as the case may be, of all the responsibilities, duties and
liabilities of the Master Servicer or the Special Servicer, as the case may be,
hereunder. Pending appointment of a successor to the Master Servicer or the
Special Servicer, as the case may be, hereunder, the Trustee shall act in such
capacity as hereinabove provided. In connection with any such appointment and
assumption described herein, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans, Companion
Loans or otherwise as it and such successor shall agree; provided, however, that
no such compensation shall be in excess of that permitted the resigning or
terminated party hereunder. The Depositor, the Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. The Trustee shall be reimbursed for all of its
out-of-pocket expenses incurred in connection with obtaining such successor
servicer by the Trust within 60 days of the Trustee's submission of an invoice
with respect thereto and after making reasonable efforts to collect such amounts
from the successor servicer, to the extent such expenses have not been
reimbursed by the successor servicer; such expenses paid by the Trust Fund shall
be deemed to be an Additional Trust Fund Expense.

         SECTION 7.03 Notification to Certificateholders and Others.

         (a) Upon any resignation of the Master Servicer or the Special Servicer
pursuant to Section 6.04, any termination of the Master Servicer or the Special
Servicer pursuant to Section 7.01 or any appointment of a successor to the
Master Servicer or the Special Servicer pursuant to Section 7.02, the Trustee
shall give prompt written notice thereof to Certificateholders at their
respective addresses appearing in the Certificate Register.

         (b) Not later than the later of (i) 60 days after the occurrence of any
event which constitutes or, with notice or lapse of time or both, would
constitute an Event of Default and (ii) five days after the Trustee would be
deemed to have notice of the occurrence of such an event in accordance with
Section 8.02(vii), the Trustee shall transmit by mail to the Depositor and all
Certificateholders notice of such occurrence, unless such default shall have
been cured.

         SECTION 7.04 Waiver of Events of Default.

         The Holders of Certificates representing at least 66 2/3% of the Voting
Rights allocated to the Classes of Certificates affected by any Event of Default
hereunder may waive such Event of Default; provided, however, that an Event of
Default under clause (i) or (ii) of Section 7.01 may be waived only by all of
the Certificateholders of the affected Classes. Upon any such waiver of an Event
of Default, such 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 Event of Default or impair any right consequent thereon
except to the extent expressly so waived. Notwithstanding any other provisions
of this Agreement, for purposes of waiving any Event of Default pursuant to this
Section 7.04, Certificates registered in the name of the Depositor or any
Affiliate of the Depositor shall be entitled to the same Voting Rights with
respect to the matters described above as they would if any other Person held
such Certificates.

                                  ARTICLE VIII

                   CONCERNING THE TRUSTEE AND THE FISCAL AGENT

         SECTION 8.01 Duties of Trustee and Fiscal Agent.

         (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If an Event of Default occurs and is continuing, the
Trustee (other than as successor Master Servicer or Special Servicer) 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 man would
exercise or use under the circumstances in the conduct of his own affairs. Any
permissive right of the Trustee contained in this Agreement shall not be
construed as a duty.

         (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement (other than the Mortgage Files, the review of which
is specifically governed by the terms of Article II), shall examine them to
determine whether they conform to the requirements of this Agreement. If any

                                      167
<PAGE>

such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take such action as it deems appropriate to
have the instrument corrected. Neither the Trustee, nor the Fiscal Agent shall
be responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Depositor, the Master Servicer or the Special Servicer or any other person and
accepted by the Trustee in good faith, pursuant to this Agreement.

         (c) No provision of this Agreement shall be construed to relieve the
Trustee or the Fiscal Agent from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct; provided, however, that:

                  (i) Prior to the occurrence of an Event of Default, and after
         the curing of all such Events of Default which may have occurred, the
         duties and obligations of the Trustee and the Fiscal Agent shall be
         determined solely by the express provisions of this Agreement, the
         Trustee and the Fiscal Agent shall not be liable except for the
         performance of such duties and obligations as are specifically set
         forth in this Agreement, no implied covenants or obligations shall be
         read into this Agreement against the Trustee or the Fiscal Agent and,
         in the absence of bad faith on the part of the Trustee or the Fiscal
         Agent, the Trustee and the Fiscal Agent 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 Fiscal Agent and conforming to the requirements of this
         Agreement;

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

                  (iii) The Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the direction of Holders of Certificates
         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 the Trustee, or exercising any trust or power conferred upon the
         Trustee, under this Agreement.

                  SECTION 8.02 Certain Matters Affecting the Trustee.

                  Except as otherwise provided in Section 8.01:

                  (i) The Trustee and the Fiscal Agent may rely upon and shall
         be protected in acting or refraining from acting upon any resolution,
         Officer's 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) The Trustee and the Fiscal Agent may consult with counsel
         and the written advice of such counsel or any Opinion of Counsel shall
         be full and complete

                                      168
<PAGE>

         authorization and protection in respect of any action taken or suffered
         or omitted by it hereunder in good faith and in accordance therewith
         and the expense of such consultation with counsel shall be reimbursable
         under Section 8.05(b) hereof;

                  (iii) Neither the Trustee nor the Fiscal Agent (in their
         respective capacities as such) shall be under any obligation to
         exercise any of the trusts or powers vested in it by this Agreement or
         to make any investigation of matters arising hereunder 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 Fiscal Agent, as applicable,
         reasonable security or indemnity against the costs, expenses and
         liabilities which may be incurred therein or thereby; neither the
         Trustee nor the Fiscal Agent shall be required to expend or risk its
         own funds or otherwise incur any financial liability in the performance
         of any of its duties hereunder, or in the exercise of any of its rights
         or powers, if it shall have reasonable grounds for believing that
         repayment of such funds or adequate indemnity against such risk or
         liability is not reasonably assured to it; nothing contained herein
         shall, however, relieve the Trustee of the obligation, upon the
         occurrence of an Event of Default which has not been cured, 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
         man would exercise or use under the circumstances in the conduct of his
         own affairs;

                  (iv) Neither the Trustee nor the Fiscal Agent shall be
         personally liable for any action reasonably 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 an Event of Default hereunder
         and after the curing of all Events of Default which may have occurred,
         the Trustee shall not be bound to make any investigation into the facts
         or matters stated in any resolution, certificate, statement,
         instrument, opinion, report, notice, request, consent, order, approval,
         bond or other paper or document, unless requested in writing to do so
         by Holders of Certificates entitled to at least 50% of the Voting
         Rights; provided, however, that if the payment within a reasonable time
         to the Trustee 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, not reasonably assured to the Trustee by the security
         afforded to it by the terms of this Agreement, the Trustee may require
         reasonable indemnity against such expense or liability as a condition
         to taking any such action;

                  (vi) The Trustee nor the Fiscal Agent may execute any of the
         trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, provided that the Trustee shall not
         be relieved from such duties, and the Trustee shall remain responsible
         for all acts and omissions of any such agent;

                  (vii) For all purposes under this Agreement, the Trustee shall
         not be deemed to have notice of any Event of Default unless a
         Responsible Officer of the Trustee has actual knowledge thereof or
         unless written notice of any event which is in

                                      169
<PAGE>

         fact such a default is received by the Trustee at the Corporate Trust
         Office, and such notice references the Certificates or this Agreement;
         and

                  (viii) Neither the Trustee nor the Fiscal Agent shall be
         responsible for any act or omission of the Master Servicer or the
         Special Servicer (unless the Trustee is acting as Master Servicer or
         the Special Servicer, as the case may be) or of the Depositor or any
         other person.

                  SECTION 8.03 Trustee and Fiscal Agent not Liable for Validity
                               or Sufficiency of Certificates or Mortgage Loans
                               or Companion Loans.

                  The recitals contained herein and in the Certificates, other
than the representations and warranties of, and the other statements attributed
to the Trustee in Sections 2.02, 2.05, 2.07 and 8.13 and the signature of the
Trustee set forth on each outstanding Certificate, shall be taken as the
statements of the Depositor, the Master Servicer or the Special Servicer, as the
case may be, and neither the Trustee nor the Fiscal Agent assume responsibility
for their correctness. Neither the Trustee nor the Fiscal Agent make any
representations as to the validity or sufficiency of this Agreement (except to
the extent set forth in Section 8.13) or of any Certificate (other than as to
the signature of the Trustee set forth thereon) or of any Mortgage Loan,
Companion Loan or related document. Neither the Trustee nor the Fiscal Agent
shall be accountable for the use or application by the Depositor of any of the
Certificates issued to it or of the proceeds of such Certificates, or for the
use or application of any funds paid to the Depositor in respect of the
assignment of the Mortgage Loans and Companion Loans to the Trust Fund, or any
funds deposited in or withdrawn from the Collection Account or any other account
by or on behalf of the Depositor, the Master Servicer or the Special Servicer.
Neither the Trustee nor the Fiscal Agent shall be responsible for the accuracy
or content of any resolution, certificate, statement, opinion, report, document,
order or other instrument furnished by the Depositor, the Master Servicer or the
Special Servicer, and accepted by the Trustee or the Fiscal Agent in good faith,
pursuant to this Agreement.

                  SECTION 8.04 Trustee and Fiscal Agent May Own Certificates.

                  Each of the Trustee and the Fiscal Agent, in their individual
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 the Fiscal Agent.

                  SECTION 8.05 Fees and Expenses of Trustee; Indemnification of
                               Trustee and Fiscal Agent.

                  (a) Monthly, the Trustee shall be entitled to withdraw the
         Trustee Fee from the Certificate Distribution Account pursuant to
         Section 3.05(b) for all services rendered by it in the execution of the
         trusts hereby created and in the exercise and performance of any of the
         powers and duties hereunder of the Trustee. As to each Mortgage Loan,
         Companion Loan and REO Loan, the Trustee Fee shall accrue from time to
         time at the Trustee Fee Rate and shall be computed on the same basis
         and the same principal amount respecting which any related interest
         payment due on such Mortgage Loan, Companion Loan or deemed to be due
         on such REO Loan is computed. On or prior to the Distribution Date in
         each month, the Trustee shall be entitled to

                                      170
<PAGE>

         withdraw and pay itself from amounts then on deposit in the
         Distribution Account an amount equal to the then unpaid Trustee Fees.

         (b) The Trustee, Fiscal Agent and any director, officer, employee or
agent of the Trustee and the Fiscal Agent and any of its directors, officers,
employees or agents shall be indemnified and held harmless by the Trust Fund (to
the extent of amounts on deposit in the applicable Distribution Account from
time to time) against any loss, liability or expense (including, without
limitation, costs and expenses of litigation, and of investigation, counsel
fees, damages, judgments and amounts paid in settlement) arising out of, or
incurred in connection with, any act or omission of the Trustee and the Fiscal
Agent relating to the exercise and performance of any of the powers and duties
of the Trustee and the Fiscal Agent hereunder; provided that neither the
Trustee, the Fiscal Agent nor any of the other above specified Persons shall be
entitled to indemnification pursuant to this Section 8.05(b) for (i) allocable
overhead, (ii) expenses or disbursements incurred or made by or on behalf of the
Trustee or the Fiscal Agent in the normal course of the Trustee's and the Fiscal
Agent's performing their routine duties in accordance with any of the provisions
hereof, (iii) any expense or liability specifically required to be borne thereby
pursuant to the terms hereof, or (iv) any loss, liability or expense incurred by
reason of willful misfeasance, bad faith or negligence in the performance of the
Trustee's or Fiscal Agent's obligations and duties hereunder, or by reason of
reckless disregard of such obligations or duties, or as may arise from a breach
of any representation, warranty or covenant of the Trustee or Fiscal Agent made
herein. The provisions of this Section 8.05(b) shall survive any resignation or
removal of the Trustee and appointment of a successor trustee or fiscal agent.

         SECTION 8.06 Eligibility Requirements for Trustee and Fiscal Agent.

         The Trustee hereunder shall at all times be an association or a
corporation organized and doing business under the laws of the United States of
America or any State thereof or the District of Columbia, authorized under such
laws to exercise trust powers, having a combined capital and surplus of at least
$100,000,000 and subject to supervision or examination by federal or state
authority. If such association or corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section the
combined capital and surplus of such association or corporation shall be deemed
to be its combined capital and surplus as set forth in its most recent report of
condition so published. The long-term unsecured debt obligations of the Trustee
shall at all times be rated not less than "Aa2" by Moody's and "AA" by Fitch
(or, if not rated by Fitch, otherwise acceptable to Fitch as would not result in
a qualification, downgrade or withdrawal of the rating assigned by Fitch to any
Class of Certificates) or if and for so long as a Fiscal Agent is appointed and
acting hereunder, at least investment grade by each Rating Agency (or, if not
rated by Fitch, otherwise acceptable to Fitch as would not result in a
qualification, downgrade or withdrawal of the rating assigned by Fitch to any
Class of Certificates); provided, that either the Trustee or the Fiscal Agent
shall at all times be an institution whose long term senior unsecured debt is
rated not less than "Aa2" by Moody and "AA" by Fitch or such other rating as
shall not result in the qualification, downgrade or withdrawal of any of the
ratings then assigned to the respective Classes of Certificates, as confirmed in
writing by each Rating Agency. In case at any time the Trustee or the Fiscal
Agent shall cease to be eligible in accordance with the provisions of this
Section, the Trustee or the Fiscal Agent shall resign immediately in the manner
and with the effect specified in Section 8.07; provided that if the

                                      171
<PAGE>

Trustee shall cease to be so eligible because its combined capital and surplus
is no longer at least $100,000,000 or its long-term unsecured debt rating no
longer conforms to the requirements of the immediately preceding sentence, and
if the Trustee proposes to the other parties hereto to enter into an agreement
with (and reasonably acceptable to) each of them or the Trustee appoints a
fiscal agent, and if in light of such agreement or such appointment, the
Trustee's continuing to act in such capacity would not (as evidenced in writing
by each Rating Agency) cause any Rating Agency to qualify, downgrade or withdraw
any rating assigned thereby to any Class of Certificates, then upon the
execution and delivery of such agreement or the effectiveness of such
appointment, the Trustee shall not be required to resign, and may continue in
such capacity, for so long as none of the ratings assigned by the Rating
Agencies to the Certificates is adversely affected thereby. The corporation or
association serving as Trustee may have normal banking and trust relationships
with the Depositor, the Master Servicer, the Special Servicer and their
respective Affiliates.

         SECTION 8.07 Resignation and Removal of the Trustee and the Fiscal
                      Agent.

         (a) The Trustee or the Fiscal Agent may at any time resign and be
discharged from the trusts hereby created by giving written notice thereof to
the Depositor, the Master Servicer, the Special Servicer and to all
Certificateholders. Upon receiving such notice of resignation, the Depositor
shall promptly appoint a successor trustee or fiscal agent acceptable to the
Master Servicer by written instrument, in duplicate, which instrument shall be
delivered to the resigning Trustee or the Fiscal Agent and to the successor
trustee. A copy of such instrument shall be delivered to the Master Servicer,
the Special Servicer and the Certificateholders by the Depositor. If no
successor trustee or fiscal agent shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Trustee or the Fiscal Agent may petition any court of competent
jurisdiction for the appointment of a successor trustee.

         (b) If at any time the Trustee or Fiscal Agent 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 the Master Servicer,
or if at any time the Trustee or Fiscal Agent shall become incapable of acting,
or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or
Fiscal Agent or of its property shall be appointed, or any public officer shall
take charge or control of the Trustee or Fiscal Agent or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Depositor may remove the Trustee or Fiscal Agent and appoint a successor trustee
or fiscal agent acceptable to the Master Servicer by written instrument, in
duplicate, which instrument shall be delivered to the Trustee or Fiscal Agent so
removed and to the successor trustee or fiscal agent. A copy of such instrument
shall be delivered to the Master Servicer, the Special Servicer and the
Certificateholders by the Depositor.

         (c) The Holders of Certificates entitled to at least 51% of the Voting
Rights may at any time remove the Trustee or the Fiscal Agent and appoint a
successor trustee or fiscal agent 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 Master Servicer,
one complete set to the

                                      172
<PAGE>

Trustee so removed and one complete set to the successor so appointed. A copy
of such instrument shall be delivered to the Depositor, the Special Servicer
and the remaining Certificateholders by the Master Servicer.

         (d) Any resignation or removal of the Trustee or the Fiscal Agent and
appointment of a successor trustee or fiscal agent pursuant to any of the
provisions of this Section 8.07 shall not become effective until acceptance of
appointment by the successor trustee or fiscal agent as provided in Section
8.08. Upon any succession of the Trustee or the Fiscal Agent under this
Agreement, the predecessor Trustee or the Fiscal Agent shall be entitled to the
payment of compensation and reimbursement for services rendered and expenses
incurred (including without limitation unreimbursed Advances and interest
thereon made thereby) accrued or payable up to and including the effective date
of such termination, at such times and from such sources as if the predecessor
Trustee or the Fiscal Agent had not resigned or been removed. Any resignation or
removal of the Trustee shall be deemed to be a simultaneous removal of the
Fiscal Agent hereunder.

         SECTION 8.08 Successor Trustee and Fiscal Agent.

         (a) Any successor trustee or fiscal agent appointed as provided in
Section 8.07 shall execute, acknowledge and deliver to the Depositor, the Master
Servicer, the Special Servicer and to its predecessor trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor trustee or fiscal agent shall become effective and such
successor trustee or fiscal agent, 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 fiscal agent herein. The predecessor trustee or fiscal agent shall
deliver to the successor trustee or fiscal agent all Mortgage Files and related
documents and statements held by it hereunder (other than any Mortgage Files at
the time held on its behalf by a Custodian, which Custodian shall become the
agent of the successor trustee), and the Depositor, the Master Servicer, the
Special Servicer and the predecessor trustee or fiscal agent shall execute and
deliver such instruments and do such other things as may reasonably be required
to more fully and certainly vest and confirm in the successor trustee all such
rights, powers, duties and obligations, and to enable the successor trustee and
fiscal agent, if applicable, to perform its obligations hereunder.

         (b) No successor trustee or fiscal agent shall accept appointment as
provided in this Section 8.08 unless at the time of such acceptance such
successor trustee or fiscal agent shall be eligible under the provisions of
Section 8.06.

         (c) Upon acceptance of appointment by a successor trustee as provided
in this Section 8.08, the successor trustee or fiscal agent shall mail notice of
such appointment to the Depositor and the Certificateholders.

         SECTION 8.09 Merger or Consolidation of Trustee and Fiscal Agent.

         Any entity into which the Trustee or the Fiscal Agent may be merged or
converted or with which it may be consolidated or any entity resulting from any
merger, conversion or consolidation to which the Trustee or the Fiscal Agent
shall be a party, or any entity succeeding to the corporate trust business of
the Trustee or the Fiscal Agent, shall be the

                                      173
<PAGE>

successor of the Trustee or the Fiscal Agent hereunder, provided such entity
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.

         (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.10, such powers, duties, obligations, rights and trusts as the Master Servicer
and the Trustee may consider necessary or desirable. If the Master Servicer
shall not have joined in such appointment within fifteen days after the receipt
by it of a request to do so, or in case an Event of Default in respect of the
Master Servicer shall have occurred and be continuing, the Trustee alone shall
have the power to make such appointment. No co-trustee or separate trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under Section 8.06 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.

         (b) 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 (whether as Trustee hereunder or
as successor to the Master Servicer or the Special 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 the Trust Fund 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.

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

         (d) 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

                                      174
<PAGE>

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.

         (e) The appointment of a co-trustee or separate trustee under this
Section 8.10 shall not relieve the Trustee of its duties and responsibilities
hereunder.

         SECTION 8.11 Appointment of Custodians.

         The Trustee may, with the consent of the Master Servicer, appoint one
or more Custodians to hold all or a portion of the Mortgage Files as agent for
the Trustee. Each Custodian shall be a depository institution subject to
supervision by federal or state authority, shall itself (or together with an
affiliate guaranteeing its financial performance) have a combined capital and
surplus of at least $15,000,000, shall have long-term unsecured debt obligation
ratings from Fitch of at least "BBB" or be otherwise acceptable to Fitch, shall
be qualified to do business in the jurisdiction in which it holds any Mortgage
File, shall maintain and keep in full force and effect throughout the term of
this Agreement a fidelity bond and an errors and omissions insurance policy
covering its officers and employees and other persons acting on its behalf in
connection with its activities under the Agreement in the amount of coverage
customary for custodians acting in such capacity, and shall not be the
Depositor, a Mortgage Loan Seller or any Affiliate of the Depositor or a
Mortgage Loan Seller. Each Custodian shall be subject to the same obligations
and standard of care as would be imposed on the Trustee hereunder in connection
with the retention of Mortgage Files directly by the Trustee. The appointment of
one or more Custodians shall not relieve the Trustee from any of its obligations
hereunder, and the Trustee shall remain responsible for all acts and omissions
of any Custodian.

         SECTION 8.12 Access to Certain Information.

         (a) On or prior to the date of the first sale of any Non-Registered
Certificate to an Independent third party, the Depositor shall provide to the
Trustee ten copies of any private placement memorandum or other disclosure
document used by the Depositor or its Affiliate in connection with the offer and
sale of the Class of Certificates to which such Non-Registered Certificate
belongs. 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 Trustee, the Depositor promptly shall inform the Trustee of such
event and shall deliver to the Trustee ten copies of the private placement
memorandum or disclosure document, as revised, amended or supplemented. The
Trustee shall maintain at its offices primarily responsible for administering
the Trust Fund (or at the Primary Servicing Office of the Master Servicer) and
shall, upon reasonable advance notice, make available during normal business
hours for review by any Holder, Certificate Owner or prospective transferee of a
Certificate or interest therein, originals or copies of the following items: (i)
in the case of a Holder, Certificate Owner or prospective transferee of a
Non-Registered Certificate or interest therein, any private placement memorandum
or other disclosure document relating to the Class of Certificates to which such
Non-Registered Certificate belongs, in the form most recently provided to the
Trustee; and (ii) in all cases, (A) this Agreement and any amendments hereto
entered into pursuant to Section 11.01, (B) all reports required to be delivered

Closing Date, (C) all Officer's Certificates delivered to the Trustee since the
Closing Date pursuant to Section 3.13, (D) all accountants' reports delivered to
the Trustee

or the Special Servicer and delivered to the Trustee pursuant to Section
3.12(b), (G) any and all notices and reports delivered to the Trustee with
respect to any Mortgaged Property securing a defaulted Mortgage Loan or
Companion Loan as to which the environmental testing contemplated by Section
3.09(c) revealed that either of the conditions set forth in clauses (i) and (ii)
of the first sentence thereof was not satisfied (but only for so long as such
Mortgaged Property or the related Mortgage Loan or Companion Loan are part of
the Trust Fund), (H) the respective Mortgage Files, including, without
limitation, any and all modifications, waivers and amendments of the terms of a
Mortgage Loan or Companion Loan entered into by the Master Servicer or the
Special Servicer and delivered to the Trustee pursuant to Section 3.20 (but only
for so long as the affected Mortgage Loan or Companion Loan is part of the Trust
Fund), (I) copies of any Appraisals performed as a result of an Appraisal
Reduction Event, and (J) any and all Officer's Certificates and other evidence
delivered to or retained by the Trustee to support the Master Servicer's,
Special Servicer's, or Trustee's or Fiscal Agent's determination that any
Advance was or, if made, would be a Nonrecoverable Advance. Copies of any and
all of the foregoing items will be available from the Trustee upon written
request; however, the Trustee shall be permitted to require from the requesting
Certificateholder payment of a sum sufficient to cover the reasonable costs and
expenses of providing such copies.

         In connection with providing access to or copies of the items described
in the preceding paragraph, the Trustee may require (a) in the case of
Certificate Owners, a written confirmation executed by the requesting Person, in
form reasonably satisfactory to the Trustee, generally to the effect that such
Person is a beneficial holder of Certificates, is requesting the information
solely for use in evaluating such Person's investment in the Certificates and
will otherwise keep such information confidential and (b) in the case of a
prospective purchaser, a written confirmation executed by the requesting Person,
in form reasonably satisfactory to the Trustee, generally to the effect that
such Person is a prospective purchaser of a Certificate or an interest therein,
is requesting the information solely for use in evaluating a possible investment
in Certificates and will otherwise keep such information confidential. All
Certificateholders, by the acceptance of their Certificates, shall be deemed to
have agreed to keep such information confidential. Notwithstanding the foregoing
provisions of this Section 8.12(a), the Trustee shall have no responsibility for
the accuracy, completeness or sufficiency for any purpose of any information so
made available or furnished by it pursuant to this Section 8.12(a).

         (b) The Trustee shall provide or cause to be provided to the Depositor,
the Master Servicer, and the Special Servicer, and to the Office of Thrift
Supervision, the Federal Deposit Insurance Corporation, and any other federal or
state banking or insurance regulatory authority that may exercise authority over
any Certificateholder, access to the Mortgage Files and any other documentation
regarding the Mortgage Loans, Companion Loans and the Trust Fund within its
control which may be required by this Agreement or by applicable law. Such
access shall be afforded without charge but only upon reasonable prior written
request and during normal business hours at the offices of the Trustee
designated by it.

         (a) The Trustee hereby represents and warrants to the Master Servicer,
for its own benefit and the benefit of the Certificateholders, and to the
Special Servicer and the Depositor, as of the Closing Date, that:

                  (i) The Trustee 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 the
         Trustee, and the performance and compliance with the terms of this
         Agreement by the Trustee, will not violate the Trustee's organizational
         documents 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) This Agreement, assuming due authorization, execution
         and delivery by the Special Servicer, the Master Servicer, the Fiscal
         Agent and the Depositor, constitutes a valid, legal and binding
         obligation of the Trustee, enforceable against the Trustee in
         accordance with the terms hereof, subject to applicable bankruptcy,
         insolvency, reorganization, moratorium and other laws affecting the
         enforcement of creditor's rights generally, and general principles of
         equity, regardless of whether such enforcement is considered in a
         proceeding in equity or at law.

                  (iv) The Trustee is not in default with respect to any order
         or decree of any court, or any order, regulation or demand of any
         federal, state, municipal or governmental agency having jurisdiction,
         which default, in the Trustee's good faith and reasonable judgment, is
         likely to affect materially and adversely the ability of the Trustee to
         perform its obligations or the financial condition or operations of the
         Trustee or its properties.

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

                  (vi) No consent, approval, authorization or order of,
         registration or filing with or notice to, any governmental authority or
         court is required, under federal or state law, for the execution,
         delivery and performance of or compliance by the Trustee with this
         Agreement, or the consummation by the Trustee of any transaction
         contemplated hereby, other than (1) such consents, approvals,
         authorization, qualifications, registrations, filings or notices as
         have been obtained or made and (2) where the lack of such consent,
         approval, authorization, qualification, registration, filing or notice
         would not have a material adverse effect on performance by the Trustee
         under this Agreement.

         Fiscal Agent, and the performance and compliance with the terms of this
         Agreement by the Fiscal Agent, will not violate the Fiscal Agent's
         organizational documents 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.

         and delivery by the Special Servicer, the Master Servicer, the Trustee
         and the Depositor, constitutes a valid, legal and binding obligation of
         the Fiscal Agent, enforceable against the Fiscal Agent in accordance
         with the terms hereof, subject to applicable bankruptcy, insolvency,
         reorganization, moratorium and other laws affecting the enforcement of
         creditors' rights generally, and general principles of equity,
         regardless of whether such enforcement is considered in a proceeding in
         equity or at law.

                  (iv) The Fiscal Agent is not in default with respect to any
         order or decree of any court, or any order, regulation or demand of any
         federal, state, municipal or governmental agency, which default, in the

                  (v) No litigation is pending or, to the best of the Fiscal
         Agent's knowledge, threatened against the Fiscal Agent which would
         prohibit the Fiscal Agent from entering into this Agreement or, in the
         Fiscal Agent's good faith and reasonable judgment, is likely to
         materially and adversely affect the ability of the Fiscal Agent to
         perform its obligations under this Agreement.

                  (vi) No consent, approval, authorization or order of,
         registration or filing with or notice to, any governmental authority or
         court is required, under federal or state law for the execution,
         delivery and performance of or compliance by the Fiscal Agent with this
         Agreement, or the consummation by the Fiscal Agent of any transaction
         contemplated hereby, other than (1) such consents, approvals,
         authorizations qualifications, registrations, filings or notices as
         have been obtained or made and (2) where the lack of such consent,
         approval, authorization, qualification, registration, filing or notice
         would not have a material adverse effect on the performance by the
         Fiscal Agent under this Agreement.

<PAGE>

                  (vi) The long-term unsecured debt of the Fiscal Agent is rated

and rights hereunder as Fiscal Agent.

                                   ARTICLE IX

                                   TERMINATION

         SECTION 9.01 Termination Upon Repurchase or Liquidation of All Mortgage
                      Loans and Companion Loans.

         Subject to Section 9.02, the Trust Fund and the respective obligations
and responsibilities under this Agreement of the Depositor, the Master Servicer,
the Special Servicer, the Fiscal Agent and the Trustee (other than the
obligations of the Trustee to provide for and make payments to
Certificateholders as hereafter set forth) shall terminate upon payment (or
provision for payment) to the Certificateholders of all amounts held by or on
behalf of the Trustee and required hereunder to be so paid on the Distribution
Date following the earlier to occur of (i) the purchase by the Master Servicer
or the Depositor of all Mortgage Loans, Companion Loans and each REO Property
remaining in REMIC I at a price (to be determined as of the end of the
Collection Period for the anticipated Final Distribution Date) equal to (A) the
aggregate Purchase Price of all the Mortgage Loans and Companion Loans included
in REMIC I, plus (B) the appraised value of each REO Property, if any, included
in REMIC I (such appraisal to be conducted by an Independent MAI-designated
appraiser selected by the Master Servicer and approved by the Trustee), minus
(C) solely in the case where the Master Servicer is effecting such purchase, the
aggregate amount of unreimbursed Advances, together with any Advance Interest
accrued and payable to the Master Servicer in respect of such Advances and any
unpaid Servicing Fees, remaining outstanding (which items shall be deemed to
have been paid or reimbursed to the Master Servicer in connection with such
purchase); provided, however, that any such purchase with respect to the
Additional Servicing Fee Mortgage Loans shall be subject to the rights of the
applicable Designated Sub-Servicer to continue to sub-service such Additional
Servicing Fee Mortgage Loans and the rights of Archon Financial, L.P., the
applicable Designated Sub-Servicer and the Master Servicer to receive or retain
their applicable portion, if any, of the Additional Servicing Fee pursuant to
the applicable Designated Sub-Servicer Agreement, and (ii) the final payment or
other liquidation (or any advance with respect thereto) of the last Mortgage
Loan, Companion Loan or REO Property remaining in REMIC I; provided, however,
that in no event shall the trust created hereby continue beyond the expiration

                                      180
<PAGE>

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 Master Servicer or the Depositor each may, at its option, elect to
purchase all of the Mortgage Loans, Companion Loans and each REO Property
remaining in the Trust Fund as contemplated by clause (i) of the preceding
paragraph by giving written notice to the other parties hereto no later than 60
days prior to the anticipated date of purchase; provided, however, that the
Master Servicer or the Depositor may so elect to purchase all of the Mortgage
Loans, Companion Loans and each REO Property remaining in REMIC I only if the
aggregate Stated Principal Balance of the Mortgage Loans and any REO Loans
remaining in the Trust Fund at the time of such election is less than 1% of the
aggregate Cut-off Date Principal Balance of the Mortgage Loans (excluding any
Companion Loans) set forth in the Preliminary Statement. Such option shall be
exercisable by each such Person in the priority in which such Person is listed
in the immediately foregoing sentence. In the event that the Master Servicer or
the Depositor purchases all of the Mortgage Loans, Companion Loans and each REO
Property remaining in REMIC I in accordance with the preceding sentence, the
Master Servicer or the Depositor, as applicable, shall deposit in the
Certificate Distribution Account or any applicable Companion Loan Distribution
Account not later than the Master Servicer Remittance Date relating to the
Distribution Date on which the final distribution on the Certificates is to
occur, an amount in immediately available funds equal to the above-described
purchase price (exclusive of any portion thereof that would be payable to any
Person other than the Certificateholders pursuant to Section 3.05(a) if on
deposit in the Collection Account, which portion shall be deposited in the
Collection Account). In addition, the Master Servicer shall transfer to the
Certificate Distribution Account or any applicable Companion Loan Distribution
Account all amounts required to be transferred thereto on such Master Servicer
Remittance Date from the Collection Account pursuant to Section 3.04(b),
together with any other amounts on deposit in the Collection Account that would
otherwise be held for future distribution. Upon confirmation that such final
deposits have been made, the Trustee shall release or cause to be released to
the Master Servicer or the Depositor, as applicable, the Mortgage Files for the
remaining Mortgage Loans and Companion Loans and any Reserve Funds and Escrow
Payments in any Reserve Accounts or Servicing Account, as applicable, and shall
execute all assignments, endorsements and other instruments furnished to it by
the Master Servicer or the Depositor, as applicable, as shall be necessary to
effectuate transfer of the Mortgage Loans, Companion Loans and REO Properties
remaining in REMIC I. All Credit Files for the remaining Mortgage Loans,
Companion Loans and REO Properties shall be delivered to the purchasing entity.

         Notice of any termination shall be given promptly by the Trustee by
letter to Certificateholders and, if not previously notified pursuant to the
preceding paragraph, to the other parties hereto mailed (a) in the event such
notice is given in connection with the Master Servicer's or the Depositor's
purchase of all of the Mortgage Loans, Companion Loans and each REO Property
remaining in REMIC I, 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, (ii) the amount of any such final payment and
(iii) that the Record Date otherwise applicable to such Distribution Date is not

                                      181
<PAGE>

applicable, payments being made only upon presentation and surrender of the
Certificates at the offices of the Certificate Registrar or such other location
therein designated.

         Upon presentation and surrender of the Certificates by the
Certificateholders on the final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates such
Certificateholder's Percentage Interest of that portion of the amounts then on
deposit in the Certificate Distribution Account or any applicable Companion Loan
Distribution Account that are allocable to payments on the Class to which the
Certificates so presented and surrendered belong. Amounts on deposit in the
applicable Distribution Account as of the final Distribution Date (exclusive of
any portion of such amounts payable or reimbursable to any Person pursuant to
clauses (ii)-(viii) of Section 3.05(b)) shall be allocated for the purposes, in
the amounts and in accordance with the priority set forth in Section 4.01. Any
funds not distributed on such Distribution Date shall be set aside and held
uninvested in trust for the benefit of Certificateholders not presenting and
surrendering their Certificates in the aforesaid manner, and shall be disposed
of in accordance with the last paragraph of Section 4.01(g).

         SECTION 9.02 Additional Termination Requirements.

         (a) In the event the Master Servicer or the Depositor purchases all of
the Mortgage Loans, Companion Loans and each REO Property remaining in REMIC I
as provided in Section 9.01, the Trust Fund (and, accordingly, REMIC I, REMIC II
and REMIC III) shall be terminated in accordance with the following additional
requirements, unless the Master Servicer or the Depositor, as the case may be,
obtains at its own expense and delivers to the Trustee an Opinion of Counsel,
addressed to the Depositor, the Master Servicer and the Trustee, to the effect
that the failure of the Trust Fund to comply with the requirements of this
Section 9.02 will not (subject to Section 10.01(f)) result in the imposition of
taxes on "prohibited transactions" of REMIC I, REMIC II or REMIC III as defined
in Section 860F of the Code or cause REMIC I, REMIC II or REMIC III to fail to
qualify as a REMIC at any time that any Certificates are outstanding:

                  (i) the Trustee shall specify the first day in the 90-day
         liquidation period in a statement attached to the final Tax Return for
         each of REMIC I, REMIC II and REMIC III pursuant to Treasury regulation
         Section 1.860F-1 and shall satisfy all requirements of a qualified
         liquidation under Section 860F of the Code and any regulations
         thereunder;

                  (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
         or the Depositor, as applicable, for cash; and

                  (iii) immediately following the making of the final payment on
         the Certificates, the Trustee shall distribute or credit, or cause to
         be distributed or credited, to the Holders of the related Class of
         Residual Certificates all cash on hand in the related REMIC (other than
         cash retained to meet claims), and REMIC I, REMIC II and REMIC III
         shall terminate at that time.

                                      182
<PAGE>

         (b) By their acceptance of Certificates, the Holders thereof hereby
agree to authorize the Trustee to adopt a plan of complete liquidation of REMIC
I, REMIC II and REMIC III, which authorization shall be binding upon all
successor Certificateholders.

                           ADDITIONAL REMIC PROVISIONS

         SECTION 10.01 REMIC Administration.

         (a) The Trustee shall make an election to treat each of REMIC I, REMIC
II and REMIC III as a REMIC under the Code and, if necessary, under applicable
state law. Such election will be made on Form 1066 or other appropriate federal
tax or information return (including Form 8811) or any appropriate state return
for the taxable year ending on the last day of the calendar year in which the
Certificates are issued. The REMIC I Regular Interests are hereby designated as
the "regular interests" (within the meaning of Section 860G(a)(1) of the Code),
and the Class R-I Certificates are hereby designated as the sole class of
"residual interests" (within the meaning of Section 860G(a)(2) of the Code), in
REMIC I. The REMIC II Regular Interests are hereby designated as the "regular
interests" (within the meaning of Section 860G(a)(1) of the Code), and the Class
R-II Certificates are hereby designated as the sole class of "residual
interests" (within the meaning of Section 860G(a)(2) of the Code), in REMIC II.
The REMIC III Regular Certificates are hereby designated as the "regular
interests" (within the meaning of Section 860G(a)(1) of the Code) and the Class
R-III Certificates will be the sole class of "residual interests" (within the
meaning of Section 860G(a)(2) of the Code), in REMIC III. The Master Servicer,
the Special Servicer and the Trustee shall not (to the extent within the control
of each) permit the creation of any "interests" (within the meaning of Section
860G of the Code) in REMIC I, REMIC II or REMIC III other than the Certificates.

         (b) The Closing Date is hereby designated as the "startup day" of each
of REMIC I, REMIC II and REMIC III within the meaning of Section 860G(a)(9) of
the Code.

         (c) The Trustee, as agent for the tax matters person of each of REMIC

any tax matter or controversy involving the Trust Fund 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 legal expenses, including without limitation attorneys' or accountants'
fees, and costs of any such proceeding and any liability resulting therefrom
shall be expenses of the Trust Fund and the Trustee shall be entitled to
reimbursement therefor out of amounts attributable to the Mortgage Loans,
Companion Loans, and any REO Properties on deposit in the Collection Account as
provided by Section 3.05(a) unless such legal expenses and costs are incurred by
reason of the Trustee's willful misfeasance, bad faith or negligence or
otherwise payable by the Trustee pursuant to Section 10.01(g)(i). In the case of
each of REMIC I, REMIC II and REMIC III, the Holder of Residual Certificates
representing the largest Percentage Interest in the related Class thereof shall
be designated, in the manner provided under Treasury Regulations Section
1.860F-4(d) and temporary Treasury Regulations Section 301.6231(a)(7)-1, as the
tax matters person of such REMIC. By its acceptance thereof, the Holder of
Residual Certificates representing the largest Percentage Interest in each Class
thereof hereby agrees to

                                      183
<PAGE>

irrevocably appoint the Trustee as its agent to perform all of the duties of
the tax matters person for the related REMIC created hereunder.

         (d) The Trustee shall prepare or cause to be prepared, sign and file,
in a timely manner, all of the Tax Returns that it determines are required with
respect to the Grantor Trust and each REMIC created hereunder. The expenses of
preparing such returns shall be borne by the Trustee without any right of
reimbursement therefor.

         (e) The Trustee shall provide (i) to any Transferor of a Residual
Certificate such information as is necessary for the application of any tax

(iii) to the Internal Revenue Service the name, title, address and telephone
number of the person who will serve as the representative of each of REMIC I,
REMIC II and REMIC III.

         (f) The Trustee shall take such actions and shall cause each REMIC
created hereunder to take such actions as are reasonably within the Trustee's
control and the scope of its duties more specifically set forth herein as shall
be necessary to maintain the status thereof as a REMIC under the REMIC
Provisions. The Trustee shall not knowingly or intentionally take any action,
cause REMIC I, REMIC II or REMIC III to take any action or fail to take (or fail
to cause to be taken) any action reasonably within its control and the scope of
duties more specifically set forth herein, that, under the REMIC Provisions, if
taken or not taken, as the case may be, could (i) adversely affect the status of
REMIC I, REMIC II or REMIC III as a REMIC or (ii) result (subject to the
following sentence) in the imposition of a tax upon REMIC I, REMIC II or REMIC
III (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 receives an Opinion of Counsel (at the expense of the
party seeking to take such action or, if such party fails to pay such expense,
and the Trustee determines that taking such action is in the best interest of
REMIC I, REMIC II or REMIC III and the Certificateholders, at the expense of the
Trust Fund, but in no event at the expense of the Trustee) to the effect that
the contemplated action will not, with respect to any REMIC created hereunder
adversely affect such status or, unless the Master Servicer, the Trustee, or the
Special Servicer, as applicable (or other Person acceptable to the Trustee),
determine that the monetary exposure to REMIC I, REMIC II and REMIC III is not
material and in its or their sole discretion to indemnify, to the extent
reasonably acceptable to the Trustee, the Trust Fund against the imposition of
such tax. Wherever in this Agreement a contemplated action may not be taken
because the timing of such action might result in the imposition of a tax on the
Trust Fund, or may only be taken pursuant to an Opinion of Counsel that such
action would not impose a tax on the Trust Fund, such action may nonetheless be
taken provided that the indemnity given in the preceding sentence with respect
to any taxes that might be imposed on the Trust Fund has been given and that all
other preconditions to the taking of such action have been satisfied. The
Trustee shall not take or fail to take any action (whether or not authorized
hereunder) as to which the Master Servicer 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 the Trust Fund or its

                                      184
<PAGE>

assets, or causing the Trust Fund to take any action, which is not expressly
permitted under the terms of this Agreement, each of the parties hereto will
consult with the Trustee or its designee, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to REMIC I,
REMIC II or REMIC III, and such party shall not take any such action, or cause
REMIC I, REMIC II or REMIC III to take any such action, as to which the Trustee
has advised it in writing that an Adverse REMIC Event could occur. 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 expressly permitted by this
Agreement. At all times as may be required by the Code, the Trustee will to the
extent within its control and the scope of its duties as specifically set forth
herein, maintain substantially all of the assets of REMIC I as "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 REMIC I, REMIC II or REMIC III as defined in Section 860F(a)(2) of the Code,
on "net income from foreclosure property" of REMIC I, REMIC II or REMIC III as
defined in Section 860G(c) of the Code, or on any contributions to REMIC I,
REMIC II or REMIC III 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 laws, such tax shall be charged (i) to the Trustee,
if such tax arises out of or results from a breach by the Trustee of any of its
obligations under this Agreement, (ii) to any other party hereto, if such tax
arises out of or results from a breach by such party of any of its obligations
under this Agreement, or (iii) otherwise (including, without limitation, in the
case of any tax permitted to be incurred pursuant to Section 3.17(a)) against
amounts on deposit in the applicable Distribution Account as provided by Section
3.05(b).

         (h) The Trustee shall, for federal income tax purposes, maintain books
and records with respect to each of REMIC I, REMIC II and REMIC III on a
calendar year and on an accrual basis or as otherwise may be required by the
REMIC Provisions.

         (i) Following the Startup Day, the Trustee shall not accept any
contributions of assets to the Trust Fund unless the Trustee shall have received
an Opinion of Counsel (at the expense of the party seeking to make such
contribution) to the effect that the inclusion of such assets in the Trust Fund
will not cause REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC at
any time that any Certificates are outstanding or subject such REMIC to any tax
under the REMIC Provisions or other applicable provisions of federal, state and
local law or ordinances.

         (j) None of the Master Servicer, the Special Servicer or the Trustee
shall enter into any arrangement by which REMIC I, REMIC II or REMIC III will
receive a fee or other compensation for services nor (to the extent within its
control) permit REMIC I, REMIC II or REMIC III to receive any income from assets
other than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or
"permitted investments" as defined in Section 860G(a)(5) of the Code.

         (k) Within 30 days after the Closing Date, the Trustee shall prepare
and file with the Internal Revenue Service Form 8811, "Information Return for
Real Estate Mortgage

                                      185
<PAGE>

Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations" for
each of REMIC I, REMIC II and REMIC III.

         (l) None of the Trustee, the Fiscal Agent, the Master Servicer, or the
Special Servicer shall sell, dispose of or substitute for any of the Mortgage
Loans or Companion Loans (except in connection with (i) the default, imminent
default or foreclosure of a Mortgage Loan or Companion Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of REMIC I, REMIC II or REMIC III,
(iii) the termination of the Trust Fund pursuant to Article IX of this Agreement
or (iv) a purchase of Mortgage Loans or Companion Loans pursuant to or as
contemplated by Section 2.03 or 3.18 of this Agreement) or acquire any assets
for the Trust Fund or sell or dispose of any investments in the Collection
Account, the applicable Distribution Account, or the REO Account for gain, or
accept any contributions to the Trust Fund after the Closing Date, unless it has
received an Opinion of Counsel that such sale, disposition, substitution or
acquisition will not (a) affect adversely the status of REMIC I, REMIC II or
REMIC III as a REMIC or, (b) subject to Section 10.01(f), cause REMIC I, REMIC
II or REMIC III to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions.

         SECTION 10.02 Depositor, Master Servicer, Special Servicer, Fiscal
                       Agent, Trustee to Cooperate.

         (a) The Depositor shall provide or cause to be provided to the Trustee,
within ten days after the Closing Date, all information or data that the Trustee
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.

         (b) The Master Servicer, the Special Servicer, the Fiscal Agent and the
Depositor shall each furnish such reports, certifications and information, and
access to such books and records maintained thereby, as may relate to the
Certificates or the Trust Fund and as shall be reasonably requested by the
Trustee in order to enable it to perform its duties hereunder.

         SECTION 10.03 Grantor Trust Administration.

         (a) The Trustee shall treat the Grantor Trust, for tax return
preparation purposes, as a grantor trust under the Code and, if necessary, under
applicable state law and will file appropriate federal or state Tax Returns for
each taxable year ending on or after the last day of the calendar year in which
the Certificates are issued.

         (b) The Trustee shall pay out of its own funds any and all routine tax
administration expenses of the Trust Fund incurred with respect to the Grantor
Trust (but not including any professional fees or expenses related to audits or
any administrative or judicial proceedings with respect to the Trust Fund that
involve the Internal Revenue Service or state tax authorities which
extraordinary expenses shall be payable or reimbursable to the Trustee from the
Trust Fund unless otherwise provided in Section 10.01(e) or 10.01(f)).

         (c) The Trustee shall prepare, sign and file when due all of the Tax
Returns in respect of the Grantor Trust. The expenses of preparing and filing
such returns shall be borne by

                                      186
<PAGE>

the Trustee without any right of reimbursement therefor. The other parties
hereto shall provide on a timely basis to the Trustee or its designee such
information with respect to the Grantor Trust as is in its possession and
reasonably requested by the Trustee to enable it to perform its obligations
under this Section 10.03. Without limiting the generality of the foregoing, the
Depositor, within ten days following the Trustee's request therefor, shall
provide in writing to the Trustee such information as is reasonably requested by
the Trustee for tax purposes, and the Trustee's duty to perform its reporting
and other tax compliance obligations under this Section 10.03 shall be subject
to the condition that it receives from the Depositor such information possessed
by the Depositor that is necessary to permit the Trustee to perform such
obligations.

         (d) The Trustee shall perform on behalf of the Grantor Trust all
reporting and other tax compliance duties that are required in respect thereof
under the Code, the Grantor Trust Provisions or other compliance guidance issued
by the Internal Revenue Service or any state or local taxing authority.

         (e) The Trustee shall perform its duties hereunder so as to maintain
the status of the Grantor Trust as a grantor trust under the Grantor Trust
Provisions (and the Master Servicer and the Special Servicer shall assist the
Trustee to the extent reasonably requested by the Trustee and to the extent of
information within the Trustee's, the Master Servicer's or the Special
Servicer's possession or control). None of the Trustee, Master Servicer, the
Special Servicer shall knowingly take (or cause the Grantor Trust to take) any
action or fail to take (or fail to cause to be taken) any action that, under the
Grantor Trust Provisions, if taken or not taken, as the case may be, could
adversely affect the status of the Grantor Trust as a grantor trust under the
Grantor Trust Provisions (any such adverse effect on grantor trust status, an
"Adverse Grantor Trust Event"), unless the Trustee has obtained or received an
Opinion of Counsel (at the expense of the party requesting such action or at the
expense of the Trust Fund if the Trustee seeks to take such action or to refrain
from taking any action for the benefit of the Certificateholders) to the effect
that the contemplated action will not result in an Adverse Grantor Trust Event.
None of the other parties hereto shall take any action or fail to take any
action (whether or not authorized hereunder) as to which the Trustee has advised
it in writing that the Trustee has received or obtained an Opinion of Counsel to
the effect that an Adverse Grantor Trust Event could result from such action or
failure to act. In addition, prior to taking any action with respect to the
Grantor Trust, or causing the Trust Fund to take any action, that is not
expressly permitted under the terms of this Agreement, the Master Servicer and
the Special Servicer shall consult with the Trustee or its designee, in writing,
with respect to whether such action could cause an Adverse Grantor Trust Event
to occur. Neither the Master Servicer nor the Special Servicer shall have any
liability hereunder for any action taken by it in accordance with the written
instructions of the Trustee. 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, but in no event at the cost or
expense of the Trust Fund or the Trustee. Notwithstanding any provision of this
Agreement to the contrary, the Grantor Trust Assets shall not be subject to any
expenses, costs or other charges that are attributable to the assets or
activities of REMIC I, REMIC II or REMIC III.

         (f) If any tax is imposed on the Grantor Trust, such tax, together with
all incidental costs and expenses (including, without limitation, penalties and
reasonable attorneys' fees) shall be charged to and paid by: (i) the Special
Servicer, if such tax arises out of or results

                                      187
<PAGE>

from a breach by the Special Servicer of any of its obligations under Article
III or this Section 10.03; (ii) the Master Servicer, if such tax arises out of
or results from a breach by the Master Servicer of any of its obligations under
Article III or this Section 10.03; (iii) the Trustee, if such tax arises out of
or results from a breach by the Trustee of any of its obligations under Article
IV, Article VIII or this Section 10.03; or (iv) the portion of the Trust Fund
constituting the Grantor Trust in all other instances.

         (g) The Trustee shall, for federal income tax purposes, maintain books
and records with respect to the Grantor Trust on a calendar year and on an
accrual basis.

         SECTION 11.01 Amendment.

         (a) This Agreement may be amended from time to time by the parties
hereto, without the consent of any of the Certificateholders:

                  (i) to cure any ambiguity,

                  (ii) to correct or supplement any provisions herein or
         therein, which may be inconsistent with any other provisions herein or
         therein or to correct any error,

                  (iii) to modify, eliminate or add to any of its provisions to
         such extent as shall be necessary or desirable to maintain the
         qualification of REMIC I, REMIC II or REMIC III as a REMIC at all times
         that any Certificate is outstanding or to avoid or minimize the risk of
         the imposition of any tax on REMIC I, REMIC II or REMIC III pursuant to
         the Code that would be a claim against the Trust Fund, provided that
         the Trustee has received an Opinion of Counsel to the effect that (A)
         such action is necessary or desirable to maintain such qualification or
         to avoid or minimize the risk of the imposition of any such tax and (B)
         such action will not adversely affect in any material respect the
         interests of any Certificateholder,

                  (iv) to change the timing and/or nature of deposits into the
         Collection Account or the applicable Distribution Account or to change
         the name in which the Collection Account is maintained, provided that
         (A) the Delinquency Advance Date or the Master Servicer Remittance Date
         shall in no event be later than the related Distribution Date, (B) such
         change shall not, as evidenced by an Opinion of Counsel, adversely
         affect in any material respect the interests of any Certificateholder
         and (C) such change shall not result in the downgrade, qualification or
         withdrawal of the then-current rating assigned to any Class of
         Certificates, as evidenced by a letter from each Rating Agency to such
         effect,

                  (v) to modify, eliminate or add to the provisions of Section
         5.02(d) or any other provision hereof restricting transfer of the
         Residual Certificates by virtue of their being the REMIC "residual
         interests," provided that such change shall not, as evidenced by an
         Opinion of Counsel, cause either the Trust Fund or any of the

                                      188

         Certificateholders (other than the transferor) to be subject to a
         federal tax caused by a transfer to a Person that is not a United
         States Person and a Permitted Transferee, or

                  (vi) to modify, eliminate or add any provision to this
         Agreement to provide for a book-entry registration system for the
         Certificates, or

                  (vii) to make any other provisions with respect to matters or
         questions arising under this Agreement which shall not be materially
         inconsistent with the provisions of this Agreement, provided that such
         action shall not, as evidenced by an Opinion of Counsel, adversely
         affect in any material respect the interests of any Certificateholder.

         (b) This Agreement may also be amended from time to time by the parties
hereto with the consent of the Holders of Certificates evidencing in the
aggregate not less than 66 2/3% of the Percentage Interests of each Class of
Certificates affected thereby for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Holders of Certificates of such
Class; provided, however, that no such amendment shall:

                  (i) reduce in any manner the amount of, or delay the timing
         of, payments which are required to be distributed on any Certificate
         without the consent of the Holder of such Certificate, or

                  (ii) reduce the aforesaid percentage of Certificates of any
         Class the Holders of which are required to consent to any such
         amendment, in any such case without the consent of the Holders of all
         Certificates of such Class then outstanding; or

                  (iii) modify the definition of "Servicing Standard" without
         the consent of the Holders of all Certificates then outstanding.

         (c) Notwithstanding the foregoing, the Trustee will not be entitled to
consent to any amendment hereto without having first received an Opinion or
Opinions of Counsel to the effect that (i) such amendment is permitted pursuant
to the terms of this Agreement and (ii) such amendment or the exercise of any
power granted to the Master Servicer, the Special Servicer, the Depositor, the
Trustee or any other specified person in accordance with such amendment will not
result in the imposition of a tax on REMIC I, REMIC II or REMIC III pursuant to
the REMIC Provisions or cause REMIC I, REMIC II or REMIC III to fail to qualify
as a REMIC.

         (d) Promptly after the execution of any such amendment, the Trustee
shall furnish a statement describing the amendment to each Certificateholder.

         (e) 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 Trustee may prescribe.

                                      189

         (f) The Trustee 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.

         (g) The cost of any Opinion of Counsel to be delivered pursuant to
Section 11.01(a) or (c) shall be borne by the Person seeking the related
amendment, except that if the Master Servicer or the Trustee requests any
amendment of this Agreement in furtherance of the rights and interests of
Certificateholders, the cost of any Opinion of Counsel required in connection
therewith pursuant to Section 11.01(a) or (c) shall be payable out of the
Collection Account.

         SECTION 11.02 Recordation of Agreement; Counterparts.

         (a) 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 Trust Fund on direction by
the Trustee, such direction to be given by the Trustee only upon the Trustee's
receipt of an Opinion of Counsel to be obtained by the party requesting such
recordation (the cost of which may be paid out of the Collection Account) to the
effect that such recordation materially and beneficially affects the interests
of the Certificateholders.

         (b) 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.

         (a) 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.

         (b) 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 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 third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

         (c) 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 or any Mortgage
Loan or Companion Loan, unless, with respect to any suit, action or proceeding
upon or under or with respect to this Agreement, such Holder

                                      190
<PAGE>

previously shall have given to the Trustee a written notice of default
hereunder, and of the continuance thereof, as hereinbefore provided, and unless
also (except in the case of a default by the Trustee) the Holders of
Certificates of any Class evidencing not less than 25% of the related Percentage
Interests in such Class shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee, for 60 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. The Trustee shall be under no obligation to exercise
any of the trusts or powers vested in it under this Section 11.03(c) or to
institute, conduct or defend any litigation hereunder or in relation hereto at
the request, order or direction of any of the Holders of Certificates unless
such Holders have offered to the Trustee reasonable security against the costs,
expenses and liabilities which may be incurred therein or hereby. It is
understood and intended, and expressly covenanted by each Certificateholder with
every other Certificateholder and the Trustee, 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, which priority or
preference is not otherwise provided for herein, 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 11.03(c), each and every Certificateholder and
the Trustee shall be entitled to such relief as can be given either at law or in
equity.

         SECTION 11.04 GOVERNING LAW.

INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE

         The Depositor intends that the conveyance of the Depositor's right,
title and interest in and to the Mortgage Loans and Companion Loans pursuant to
this Agreement shall constitute a sale and not a pledge of security for a loan.

meanings assigned in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

         Pursuant to the terms of the Agreement, distributions will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the month immediately preceding the month of such distribution (the "Record
Date"), in an amount equal to the product of the Percentage Interest evidenced

         The Class X Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class X
Certificates are exchangeable for new Class X Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class X Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class X Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class X Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require, in order to assure compliance with such laws, receipt by
it and the Depositor of a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached as Exhibit B-1 to the
Agreement and a certificate from such Certificateholder's prospective transferee
substantially in the form attached as Exhibit B-2 to the Agreement. Any
purchaser of a Class X Certificate shall be deemed to have represented by such
purchase that it is a "qualified institutional buyer" as that term is defined in
Rule 144A ("Rule 144A") under the Securities Act, that it is aware that the sale
to it is being made in reliance on Rule 144A and that it is acquiring the Class
X Certificates for its own account or for the account of a qualified
institutional buyer, and that it understands that such Class X Certificates may
be resold, pledged or transferred only (a) to a person reasonably believed to be
a qualified institutional buyer that purchases for its own account or for the
account of a qualified institutional buyer to whom notice is given that the
resale, pledge or transfer is being made in reliance on Rule 144A, or (b)
pursuant to another exemption from registration under the Securities Act. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class X Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class X Certificate without registration
or qualification. None of the Depositor, the Trustee or the Certificate
Registrar is obligated to register or qualify the Class X Certificates under the
Securities Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of any Class X Certificate
without registration or qualification. Any Class X Certificateholder desiring to
effect such a transfer shall, and by the acceptance of its Class X Certificate
agrees to, indemnify the Depositor, the Trustee and the Certificate Registrar
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 any Class X Certificate or any interest therein shall be
made (A) to any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, that is subject to ERISA or Section 4975 of the Code
(each, a "Plan"), or (B) to any Person who is directly or indirectly purchasing
such Certificate or interest therein on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such Plan
qualifies as an accredited investor as defined in Rule 501(a)(1) of Regulation D
of the Securities Act of 1933, as amended and (2) at the time of such transfer,
the Class X Certificates continue to be rated in one of the top four rating
categories by at least one Rating Agency or (B) such Plan is an "insurance
company general account" (within the meaning of PTE 95-60) and the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of acquisition of such Certificate.

         No service charge will be imposed for any registration of transfer or
exchange of Class X Certificates, but the Trustee or the Certificate Registrar
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 Class
X Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.

including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

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

distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the

respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class E Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class E Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class E Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                     A-7-4

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class E
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class E Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class E Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class E Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class E Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class E Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class E Certificate without registration
or qualification. Any Class E Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class E Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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 any Class E Certificate or any interest therein shall be
made (A) to any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, that is subject to ERISA or Section 4975 of the Code
(each, a "Plan"), or (B) to any Person who is directly or indirectly purchasing
such Certificate or interest therein on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such Plan
qualifies as an accredited investor as defined in Rule 501(a)(1) of Regulation D
of the Securities Act of 1933, as amended and (2) at the time of such transfer,
the Class E Certificates continue to be rated in one of the top four rating
categories by at least one Rating Agency or (B) such Plan is an "insurance
company general account" (within the meaning of PTE 95-60) and the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of acquisition of such Certificate.

         No service charge will be imposed for any registration of transfer or
exchange of Class E Certificates, but the Trustee or the Certificate Registrar
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 Class
E Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of

                                     A-7-5
<PAGE>

DTC, transfers of interests in this Certificate shall be made through the
book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

of acquisition of such Certificate.

         No service charge will be imposed for any registration of transfer or
exchange of Class F Certificates, but the Trustee or the Certificate Registrar
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 Class
F Certificates.

time by the Depositor, the Master Servicer, the Special Servicer, the Trustee

at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it

distributions hereunder.

Trustee and ABN AMRO Bank N.V., as Fiscal Agent. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

         Pursuant to the terms of the Agreement, distributions will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (each, a "Distribution Date"), commencing on

                                     A-9-3
<PAGE>

this Certificate) will be made after due notice by the Trustee of the pendency
of such distribution and only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar appointed as provided in
the Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to
this Certificate in reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to this Certificate, which reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

"Certificates") are limited in right of distribution 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

time to time for purposes other than, and, in certain cases, prior to,

Loans and the payment of interest on such advances and expenses.

         The Class G Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class G
Certificates are exchangeable for new Class G Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class G Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class G Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class G Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                     A-9-4
<PAGE>

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class G
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class G Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class G Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class G Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class G Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class G Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class G Certificate without registration
or qualification. Any Class G Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class G Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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 any Class G Certificate or any interest therein shall be
made (A) to any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, that is subject to ERISA or Section 4975 of the Code
(each, a "Plan"), or (B) to any Person who is directly or indirectly purchasing
such Certificate or interest therein on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such Plan
qualifies as an accredited investor as defined in Rule 501(a)(1) of Regulation D
of the Securities Act of 1933, as amended and (2) at the time of such transfer,
the Class G Certificates continue to be rated in one of the top four rating
categories by at least one Rating Agency or (B) such Plan is an "insurance
company general account" (within the meaning of PTE 95-60) and the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of acquisition of such Certificate.

         No service charge will be imposed for any registration of transfer or
exchange of Class G Certificates, but the Trustee or the Certificate Registrar
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 Class
G Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of

                                     A-9-5
<PAGE>

DTC, transfers of interests in this Certificate shall be made through the
book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

Trustee and ABN AMRO Bank N.V., as Fiscal Agent. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

         Pursuant to the terms of the Agreement, distributions will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this

the Certificate Register. Notwithstanding the above, the final distribution on
this Certificate (determined without regard to any possible future reimbursement

of such distribution and only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar appointed as provided in
the Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to

Expense previously allocated to this Certificate, which reimbursement is to

the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

         The Depositor's Mortgage Pass-Through Certificates, Series 2000-C3 (the
"Certificates") are limited in right of distribution 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 Certificate Distribution Account may be made from
time to time for purposes other than, and, in certain cases, prior to,
distributions to Certificateholders, such purposes including the reimbursement
of advances made, or certain expenses incurred, with respect to the Mortgage
Loans and the payment of interest on such advances and expenses.

         The Class H Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class H
Certificates are exchangeable for new Class H Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class H Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class H Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class H Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                     A-10-4
<PAGE>

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class H
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class H Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class H Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class H Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class H Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class H Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class H Certificate without registration
or qualification. Any Class H Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class H Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class H Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class H Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

                                     A-10-5
<PAGE>

         No service charge will be imposed for any registration of transfer or
exchange of Class H Certificates, but the Trustee or the Certificate Registrar
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 Class
H Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof

Trustee and ABN AMRO Bank N.V., as Fiscal Agent. To the extent not defined

in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

         Pursuant to the terms of the Agreement, distributions will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (each, a "Distribution Date"), commencing on
the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of

Certificate at the offices of the Certificate Registrar appointed as provided in
the Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to

Expense previously allocated to this Certificate, which reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

         The Depositor's Mortgage Pass-Through Certificates, Series 2000-C3 (the
"Certificates") are limited in right of distribution 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

time to time for purposes other than, and, in certain cases, prior to,

Loans and the payment of interest on such advances and expenses.

         The Class J Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class J
Certificates are exchangeable for new Class J Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class J Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class J Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class J Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                     A-11-4
<PAGE>

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class J
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class J Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class J Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class J Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class J Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class J Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class J Certificate without registration
or qualification. Any Class J Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class J Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class J Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class J Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

         No service charge will be imposed for any registration of transfer or
exchange of Class J Certificates, but the Trustee or the Certificate Registrar
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 Class
J Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

the month immediately preceding the month of such distribution (the "Record
Date"), in an amount equal to the product of the Percentage Interest evidenced
by this Certificate and the amount required to be distributed to the Holders of
the Class K Certificates on the applicable Distribution Date pursuant to the
Agreement. All distributions made under the Agreement on any Class K Certificate
will be made by the Trustee by wire transfer in immediately available funds to
the account of the Person entitled thereto at a bank or other entity having

the Trustee with wiring instructions no less than five Business Days prior to
the Record Date for such distribution (which wiring instructions may be in the
form of a standing order applicable to all subsequent distributions as well), or
otherwise by check mailed to the address of such Certificateholder appearing in
the Certificate Register. Notwithstanding the above, the final distribution on
this Certificate (determined without regard to any possible future reimbursement

                                     A-12-3
<PAGE>

of any Realized Loss or Additional Trust Fund Expense previously allocated to
this Certificate) will be made after due notice by the Trustee of the pendency
of such distribution and only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar appointed as provided in
the Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to
this Certificate in reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to this Certificate, which reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

         The Depositor's Mortgage Pass-Through Certificates, Series 2000-C3 (the
"Certificates") are limited in right of distribution 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 Certificate Distribution Account may be made from
time to time for purposes other than, and, in certain cases, prior to,
distributions to Certificateholders, such purposes including the reimbursement
of advances made, or certain expenses incurred, with respect to the Mortgage
Loans and the payment of interest on such advances and expenses.

         The Class K Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class K
Certificates are exchangeable for new Class K Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class K Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class K Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class K Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                     A-12-4
<PAGE>

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class K
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class K Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class K Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class K Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class K Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class K Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class K Certificate without registration
or qualification. Any Class K Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class K Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class K Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class K Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

                                     A-12-5
<PAGE>

         No service charge will be imposed for any registration of transfer or
exchange of Class K Certificates, but the Trustee or the Certificate Registrar
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 Class
K Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

or qualification. Any Class L Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class L Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class L Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class L Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

         No service charge will be imposed for any registration of transfer or
exchange of Class L Certificates, but the Trustee or the Certificate Registrar
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 Class
L Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Certificate Principal Balance hereof is binding on such Holder and all future

set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate

writing, and thereupon one or more new Class M Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class M Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class M Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without

                                    A-14-4
<PAGE>

registration under the Securities Act, then the Trustee shall require, in order
to assure compliance with such laws, receipt by it and the Depositor of a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit B-1 to the Agreement and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class M
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class M Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class M Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class M Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class M Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class M Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class M Certificate without registration
or qualification. Any Class M Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class M Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class M Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class M Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

         No service charge will be imposed for any registration of transfer or
exchange of Class M Certificates, but the Trustee or the Certificate Registrar
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 Class
M Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of designated portions
of the Trust Fund as a REMIC, without the consent of the Holders of any of the
Certificates.

in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of

Holder is bound.

         Pursuant to the terms of the Agreement, distributions will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (each, a "Distribution Date"), commencing on

Certificate is surrendered as contemplated by the preceding sentence, will be
made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appeared in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

         The Depositor's Mortgage Pass-Through Certificates, Series 2000-C3 (the
"Certificates") are limited in right of distribution 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

time to time for purposes other than, and, in certain cases, prior to,

Loans and the payment of interest on such advances and expenses.

         The Class N Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class N
Certificates are exchangeable for new Class N Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Class N Certificates in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

         No transfer of any Class N Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class N Certificate
(other than

                                     A-15-4
<PAGE>

a transfer thereof by the Depositor or any Affiliate of the Depositor) is to be
made without registration under the Securities Act, then the Trustee shall
require, in order to assure compliance with such laws, receipt by it and the
Depositor of a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached as Exhibit B-1 to the Agreement and
a certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class N
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class N Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class N Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class N Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class N Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class N Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class N Certificate without registration
or qualification. Any Class N Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class N Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

         Any purchaser of a Class N Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an " insurance company general account" (as such term is defined in Department
of Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions
set forth in Sections I and III of PTE 95-60 have been satisfied as of the date
of the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class N Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as

                                     A-15-5
<PAGE>

named fiduciary of, as trustee of, or with "plan assets" of a Plan or that the
conditions of an acceptable alternative representation are satisfied.

         No service charge will be imposed for any registration of transfer or
exchange of Class N Certificates, but the Trustee or the Certificate Registrar
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 Class
N Certificates.

         Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them 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
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any

                                     A-15-6
<PAGE>

amendment necessary to maintain the status of designated portions of the Trust
Fund as a REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

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

Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class O Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No transfer of any Class O Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class O Certificate
(other than

                                     A-16-4
<PAGE>

a transfer thereof by the Depositor or any Affiliate of the Depositor) is to be
made without registration under the Securities Act, then the Trustee shall
require, in order to assure compliance with such laws, receipt by it and the
Depositor of a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached as Exhibit B-1 to the Agreement and
a certificate from such Certificateholder's prospective transferee substantially
in the form attached as Exhibit B-2 to the Agreement. Any purchaser of a Class O
Certificate shall be deemed to have represented by such purchase that it is a
"qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class O Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class O Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class O Certificates under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
transfer of any Class O Certificate without registration or qualification. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class O Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class O Certificate without registration
or qualification. Any Class O Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class O Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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.

                  Any purchaser of a Class O Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an "insurance company general account" (as such term is defined in Department of
Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions set
forth in Sections I and III of PTE 95-60 have been satisfied as of the date of
the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class O Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as

                                     A-16-5

<PAGE>

named fiduciary of, as trustee of, or with "plan assets" of a Plan or that the
conditions of an acceptable alternative representation are satisfied.

                  No service charge will be imposed for any registration of
transfer or exchange of Class O Certificates, but the Trustee or the Certificate
Registrar 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 Class O Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any

                                     A-16-6

<PAGE>

amendment necessary to maintain the status of designated portions of the Trust
Fund as a REMIC, without the consent of the Holders of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

that transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class P Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require, in order to assure compliance

                                     A-17-5
<PAGE>

with such laws, receipt by it and the Depositor of a certificate from the
Certificateholder desiring to effect such transfer substantially in the form
attached as Exhibit B-1 to the Agreement and a certificate from such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the Agreement. Any purchaser of a Class P Certificate shall be
deemed to have represented by such purchase that it is a "qualified
institutional buyer" as that term is defined in Rule 144A ("Rule 144A") under
the Securities Act, that it is aware that the sale to it is being made in
reliance on Rule 144A and that it is acquiring the Class P Certificates for its
own account or for the account of a qualified institutional buyer, and that it
understands that such Class P Certificates may be resold, pledged or transferred
only (a) to a person reasonably believed to be a qualified institutional buyer
that purchases for its own account or for the account of a qualified
institutional buyer to whom notice is given that the resale, pledge or transfer
is being made in reliance on Rule 144A, or (b) pursuant to another exemption
from registration under the Securities Act. None of the Depositor, the Trustee
or the Certificate Registrar is obligated to register or qualify the Class P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class P Certificate without registration or qualification. None of the
Depositor, the Trustee or the Certificate Registrar is obligated to register or
qualify the Class P Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class P Certificate without registration or
qualification. Any Class P Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class P Certificate agrees to, indemnify the
Depositor, the Trustee and the Certificate Registrar 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.

                  Any purchaser of a Class P Certificate will be deemed to have
represented by such purchase that either (a) such purchaser is not an employee
benefit plan or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested, that is
subject to ERISA or Section 4975 of the Code (each, a "Plan") and is not
purchasing such Certificate by or on behalf of, or with "plan assets" of, any
Plan or (b) the purchase of any such Certificate by or on behalf of, or with
"plan assets" of, any Plan is permissible under applicable law, will not result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the
Code, and will not subject the Depositor, the Trustee or the Servicer to any
obligation in addition to those undertaken in the Agreement, and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an "insurance company general account" (as such term is defined in Department of
Labor Prohibited Transaction Exemption ("PTE") 95-60) and (b) the conditions set
forth in Sections I and III of PTE 95-60 have been satisfied as of the date of
the acquisition of such Certificate. The Trustee may require that any
prospective transferee of a Class P Certificate that is held as a Definitive
Certificate, provide such certifications as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such registration is requested is not a Plan or a Person who is directly or
indirectly purchasing such Certificate on behalf of, as named fiduciary of, as
trustee of, or with "plan assets" of a Plan or that the conditions of an
acceptable alternative representation are satisfied.

                  No service charge will be imposed for any registration of
transfer or exchange of Class P Certificates, but the Trustee or the Certificate
Registrar 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 Class P Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

Commercial Mortgage Securities, Inc., as Depositor, GMAC Commercial Mortgage
Corporation, as Master Servicer and Special Servicer, LaSalle Bank National
Association, as Trustee and ABN AMRO Bank N.V., as Fiscal Agent. To the extent
not defined herein, the capitalized terms used herein have the respective
meanings assigned in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 15th day of each month or, if such 15th day is not a Business Day,
the Business Day immediately following (each, a "Distribution Date"), commencing
on the First Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the last Business Day of
the month immediately preceding the month of such distribution (the "Record
Date"), in an amount equal to the product of the Percentage Interest evidenced
by this Certificate and the amount required to be distributed to the Holders of
the Class S-AM Certificates on the applicable Distribution Date pursuant to the
Agreement. All distributions made under the Agreement on any Class S-AM
Certificate will be made by the Trustee by wire transfer in immediately
available funds to the account of the Person entitled thereto at a bank or other
entity having appropriate facilities therefore, if such Certificateholder shall
have provided the Trustee with wiring instructions no less than five Business
Days prior to the Record Date for such distribution (which wiring instructions
may be in the form of a standing order applicable to all subsequent
distributions as well), or otherwise by check mailed to the address of such
Certificateholder appearing in the Certificate Register. Notwithstanding the
above, the final distribution on this Certificate (determined without regard to
any possible future reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to this Certificate) will be made after due notice
by the Trustee of the pendency of such distribution and only upon presentation
and surrender of this Certificate at the offices of the Certificate Registrar
appointed as provided in the Agreement or such other location as may be
specified in such notice. Also notwithstanding the foregoing, any distribution
that may be made with respect to this Certificate

in reimbursement of any Realized Loss or Additional Trust Fund Expense
previously allocated to this Certificate, which reimbursement is to occur after
the date on which this Certificate is surrendered as contemplated by the
preceding sentence, will be made by check mailed to the address of the Holder
that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Depositor's Mortgage Pass-Through Certificates, Series
2000-C3 (the "Certificates") are limited in right of distribution 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 Certificate
Distribution Account may be made from time to time for purposes other than, and,
in certain cases, prior to, distributions to Certificateholders, such purposes
including the reimbursement of advances made, or certain expenses incurred, with
respect to the Mortgage Loans and the payment of interest on such advances and
expenses.

                  The Class S-AM Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class S-AM Certificates are exchangeable for new Class S-AM Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class S-AM Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No transfer of any Class S-AM Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class S-AM Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require, in order to assure compliance with such laws, receipt by
it and the Depositor of a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached as Exhibit B-1 to the
Agreement and a certificate from such Certificateholder's prospective transferee
substantially in the form attached as Exhibit B-2 to the Agreement. Any
purchaser of a Class S-AM Certificate shall be deemed to have represented by
such purchase that it is a "qualified

                                     A-18-4

<PAGE>

institutional buyer" as that term is defined in Rule 144A ("Rule 144A") under
the Securities Act, that it is aware that the sale to it is being made in
reliance on Rule 144A and that it is acquiring the Class S-AM Certificates for
its own account or for the account of a qualified institutional buyer, and that
it understands that such Class S-AM Certificates may be resold, pledged or
transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class S-AM Certificates under the Securities Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of any Class S-AM Certificate without registration or qualification.
None of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class S-AM Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class S-AM Certificate without
registration or qualification. Any Class S-AM Certificateholder desiring to
effect such a transfer shall, and by the acceptance of its Class S-AM
Certificate agrees to, indemnify the Depositor, the Trustee and the Certificate
Registrar 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.

                  Any purchaser of a Class S-AM Certificate will be deemed to
have represented by such purchase that either (a) such purchaser is not an
employee benefit plan or other retirement arrangement, including individual
retirement accounts and annuities, Keogh plans and collective investment funds
and separate accounts in which such plans, accounts or arrangements are
invested, that is subject to ERISA or Section 4975 of the Code (each, a "Plan")
and is not purchasing such Certificate by or on behalf of, or with "plan assets"
of, any Plan or (b) the purchase of any such Certificate by or on behalf of, or
with "plan assets" of, any Plan is permissible under applicable law, will not
result in any non-exempt prohibited transaction under ERISA or Section 4975 of
the Code, and will not subject the Depositor, the Trustee, the Fiscal Agent or
the Servicer to any obligation in addition to those undertaken in the Agreement,
and the following conditions are met: (a) the source of funds used to purchase
such Certificate is an "insurance company general account" (as such term is
defined in Department of Labor Prohibited Transaction Exemption ("PTE") 95-60)
and (b) the conditions set forth in Sections I and III of PTE 95-60 have been
satisfied as of the date of the acquisition of such Certificate. The Trustee may
require that any prospective transferee of a Class S-AM Certificate that is held
as a Definitive Certificate, provide such certifications as the Trustee may deem
desirable or necessary in order to establish that such transferee or the Person
in whose name such registration is requested is not a Plan or a Person who is
directly or indirectly purchasing such Certificate on behalf of, as named
fiduciary of, as trustee of, or with "plan assets" of a Plan or that the
conditions of an acceptable alternative representation are satisfied.

                  No service charge will be imposed for any registration of
transfer or exchange of Class S-AM Certificates, but the Trustee or the
Certificate Registrar 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 Class S-AM Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class S-MAC-1 Certificates
in authorized denominations evidencing the same aggregate Percentage Interest
will be issued to the designated transferee or transferees.

                  No transfer of any Class S-MAC-1 Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. If such a transfer of any Class
S-MAC-1 Certificate (other than a transfer thereof by the Depositor or any
Affiliate of the Depositor) is to be made without registration under the
Securities Act, then the Trustee shall require, in order to assure compliance
with such laws, receipt by it and the Depositor of a certificate from the
Certificateholder desiring to effect such transfer substantially in the form
attached as Exhibit B-1 to the Agreement and a certificate from such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the Agreement. Any purchaser of a Class S-

MAC-1 Certificate shall be deemed to have represented by such purchase that it
is a "qualified institutional buyer" as that term is defined in Rule 144A ("Rule
144A") under the Securities Act, that it is aware that the sale to it is being
made in reliance on Rule 144A and that it is acquiring the Class S-MAC-1
Certificates for its own account or for the account of a qualified institutional
buyer, and that it understands that such Class S-MAC-1 Certificates may be
resold, pledged or transferred only (a) to a person reasonably believed to be a
qualified institutional buyer that purchases for its own account or for the
account of a qualified institutional buyer to whom notice is given that the
resale, pledge or transfer is being made in reliance on Rule 144A, or (b)
pursuant to another exemption from registration under the Securities Act. None
of the Depositor, the Trustee or the Certificate Registrar is obligated to
register or qualify the Class S-MAC-1 Certificates under the Securities Act or
any other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class S- MAC-1 Certificate without
registration or qualification. None of the Depositor, the Trustee or the
Certificate Registrar is obligated to register or qualify the Class S-MAC-1
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class S-MAC-1 Certificate without registration or qualification. Any Class
S-MAC-1 Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class S-MAC-1 Certificate agrees to, indemnify the Depositor,
the Trustee and the Certificate Registrar 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 any Class S-MAC-1 Certificate or any interest
therein shall be made (A) to any employee benefit plan or other retirement
arrangement, including individual retirement accounts and annuities, Keogh plans
and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested, that is subject to ERISA or Section 4975
of the Code (each, a "Plan"), or (B) to any Person who is directly or indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such
Plan qualifies as an accredited investor as defined in Rule 501(a)(1) of
Regulation D of the Securities Act of 1933, as amended and (2) at the time of
such transfer, the Class S-MAC-1 Certificates continue to be rated in one of the
top four rating categories by at least one Rating Agency or (B) such Plan is an
"insurance company general account" (within the meaning of PTE 95-60) and the
conditions set forth in Sections I and III of PTE 95-60 have been satisfied as
of the date of acquisition of such Certificate.

                  No service charge will be imposed for any registration of
transfer or exchange of Class S-MAC-1 Certificates, but the Trustee or the
Certificate Registrar 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 Class S-MAC-1 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

144A, or (b) pursuant to another exemption from registration under the
Securities Act. None of the Depositor, the Trustee or the Certificate Registrar
is obligated to register or qualify the Class S-MAC-3 Certificates under the
Securities Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of any Class S- MAC-3

Trustee or the Certificate Registrar is obligated to register or qualify the
Class S-MAC-3 Certificates under the Securities Act or any other securities law
or to take any action not otherwise required under the Agreement to permit the
transfer of any Class S-MAC-3 Certificate without registration or qualification.
Any Class S-MAC-3 Certificateholder desiring to effect such a transfer shall,
and by the acceptance of its Class S-MAC-3 Certificate agrees to, indemnify the
Depositor, the Trustee and the Certificate Registrar 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.

of, as trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such
Plan qualifies as an accredited investor as defined in Rule 501(a)(1) of
Regulation D of the Securities Act of 1933, as amended and (2) at the time of
such transfer, the Class S-MAC-3 Certificates continue to be rated in one of the
top four rating categories by at least one Rating Agency or (B) such Plan is an
"insurance company general account" (within the meaning of PTE 95-60) and the
conditions set forth in Sections I and III of PTE 95-60 have been satisfied as
of the date of acquisition of such Certificate.

                  No service charge will be imposed for any registration of
transfer or exchange of Class S-MAC-3 Certificates, but the Trustee or the
Certificate Registrar 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 Class S-MAC-3 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by

of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of

remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in

certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

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

that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  No transfer of any Class S-MAC-4 Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. If such a transfer of any Class
S-MAC-4 Certificate (other than a transfer thereof by the Depositor or any
Affiliate of the Depositor) is to be made without registration under the
Securities Act, then the Trustee shall require, in order to assure compliance
with such laws, receipt by it and the Depositor of a certificate from the
Certificateholder desiring to effect such transfer substantially in the form
attached as Exhibit B-1 to the Agreement and a certificate from such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the Agreement. Any purchaser of a Class S-MAC-4 Certificate shall
be deemed to have represented by such purchase that it is a "qualified
institutional buyer" as that term is defined in Rule 144A ("Rule 144A") under
the Securities Act, that it is aware that the sale to it is being made in
reliance on Rule 144A and that it is acquiring the Class S-MAC-4 Certificates
for its own account or for the account of a qualified institutional buyer, and
that it understands that such Class S-MAC-4 Certificates may be resold, pledged
or transferred only (a) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (b) pursuant to another
exemption from registration under the Securities Act. None of the Depositor, the
Trustee or the Certificate Registrar is obligated to register or qualify the
Class S-MAC-4 Certificates under the Securities Act or any other securities law
or to take any action not otherwise required under the Agreement to permit the
transfer of any Class S- MAC-4 Certificate without registration or
qualification. None of the Depositor, the Trustee or the Certificate Registrar
is obligated to register or qualify the Class S-MAC-4 Certificates under the
Securities Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of any Class S-MAC-4
Certificate without registration or qualification. Any Class S-MAC-4
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class S-MAC-4 Certificate agrees to, indemnify the Depositor,
the Trustee and the Certificate Registrar 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 any Class S-MAC-4 Certificate or any interest
therein shall be made (A) to any employee benefit plan or other retirement
arrangement, including individual retirement accounts and annuities, Keogh plans
and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested, that is subject to ERISA or Section 4975
of the Code (each, a "Plan"), or (B) to any Person who is directly or indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with "plan assets" of a Plan, unless: either (A) (1) such
Plan qualifies as an accredited investor as defined in Rule 501(a)(1) of
Regulation D of the Securities Act of 1933, as amended and (2) at the time of
such transfer, the Class S-MAC-4 Certificates continue to be rated in one of the
top four rating categories by at least one Rating Agency or (B) such Plan is an
"insurance company general account" (within the meaning of PTE 95-60) and the
conditions set forth in Sections I and III of PTE 95-60 have been satisfied as
of the date of acquisition of such Certificate.

                  No service charge will be imposed for any registration of
transfer or exchange of Class S-MAC-4 Certificates, but the Trustee or the
Certificate Registrar 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 Class S-MAC-4 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage Pool specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of designated portions of the Trust Fund as a REMIC, without the consent of the
Holders of any of the Certificates.

                  This certifies that [________________________] is the
registered owner of the Percentage Interest evidenced by this Class R-I
Certificate (as specified above) in that certain beneficial ownership interest
evidenced by all the Class R-I Certificates in the Trust Fund created pursuant

the respective meanings assigned in the Agreement. This Certificate is issued
under and is subject to the terms, provisions and conditions of the Agreement,
to which Agreement the Holder of this Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 15th day of each month or, if such 15th day is not a Business Day,
the Business Day immediately following (each, a "Distribution Date"), commencing
upon the First Distribution Date specified

                                     A-23-2
<PAGE>

above, to the Person in whose name this Certificate is registered at the close
of business on the last Business Day of the month immediately preceding the
month of such distribution (the "Record Date"), in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the amount
required to be distributed to the Holders of the Class R-I Certificates on the
applicable Distribution Date pursuant to the Agreement. All distributions made
under the Agreement on any Class R-I Certificate will be made by the Trustee by

the pendency of such distribution and only upon presentation and surrender of
this Certificate at the offices of the Certificate Registrar appointed as
provided in the Agreement or such other location as may be specified in such

                  The Depositor's Mortgage Pass-Through Certificates, Series
2000-C3 (the "Certificates") are limited in right of distribution 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 Certificate Distribution
Account may be made from time to time for purposes other than, and, in certain
cases, prior to, distributions to Certificateholders, such purposes including
the reimbursement of advances made, or certain expenses incurred, with respect
to the Mortgage Loans and the payment of interest on such advances and expenses.

                  The Class R-I Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-I Certificates are
exchangeable for new Class R-I Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-I Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No transfer of any Class R-I Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class R-I Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require, in order to assure compliance with such laws, receipt by
it and the Depositor of a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached as Exhibit B-1 to the
Agreement and a certificate from such Certificateholder's prospective transferee
substantially in the form attached as Exhibit B-2 to the Agreement. None of the
Depositor, the Trustee or the Certificate Registrar is obligated to register or
qualify the Class R-I Certificates under the Securities Act or any other

securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class R-I Certificate without registration or
qualification. Any Class R-I Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class R-I Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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 a Class R-I Certificate or any interest therein
shall be made to (A) any employee benefit plan or other retirement arrangement,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested, that is subject to ERISA or Section 4975 of the
Code (each, a "Plan") or (B) any Person who is directly or indirectly purchasing
the Class R-I Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with assets of a Plan.

                  Each Person who has or who acquires any Ownership Interest in
this Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the provisions of Section
5.02(d) of the Agreement and, if any purported Transferee shall become a Holder
of this Certificate in violation of the provisions of such Section 5.02(d), to
have irrevocably authorized the Trustee under clause (ii)(A) of such Section
5.02(d) to deliver payments to a Person other than such Person and to have
irrevocably authorized the Trustee under clause (ii)(B) of such Section 5.02(d)
to negotiate the terms of any mandatory sale and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
Each Person holding or acquiring any Ownership Interest in this Certificate must
be a Permitted Transferee and a United States Person and shall promptly notify
the Trustee of any change or impending change in its status as a Permitted
Transferee or United States Person. In connection with any proposed Transfer of
any Ownership Interest in this Certificate, the Trustee shall require delivery
to it, and shall not register the Transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit C-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, in form and substance satisfactory to the Trustee, representing and
warranting, among other things, that such Transferee is a Permitted Transferee
and a United States Person, that it is not acquiring its Ownership Interest in
this Certificate as a nominee, trustee or agent for any Person that is not a
Permitted Transferee or is not a United States Person, that for so long as it
retains its Ownership Interest in this Certificate, it will endeavor to remain a
Permitted Transferee and a United States Person, and that it has reviewed the
provisions of Section 5.02(d) of the Agreement and agrees to be bound by them.
Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed
Transferee, if the Trustee has actual knowledge that the proposed Transferee is
not a Permitted Transferee or is not a United States Person, the Trustee shall
not register the Transfer of an Ownership Interest in this Certificate to such
proposed Transferee.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any prospective Transferee to whom such Person attempts to transfer its
Ownership Interest herein and (y) not to transfer its Ownership Interest unless
it provides to the Trustee a certificate substantially in the form attached as
Exhibit C-2 to the Agreement stating that, among other things, it has no actual
knowledge that such prospective Transferee is not a Permitted Transferee or is
not a United

                                     A-23-4

States Person. Each Person holding or acquiring an Ownership Interest in this
Certificate, by purchasing such Ownership Interest herein, agrees to give the
Trustee 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 such Ownership Interest, if it is, or is holding such Ownership
Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Trustee the following: (a) written notification from each Rating Agency
to the effect that the modification of, addition to or elimination of such
provisions will not cause such Rating Agency to withdraw, qualify or downgrade
its then-current rating of any Class of Certificates; and (b) an Opinion of
Counsel, in form and substance satisfactory to the Trustee and the Depositor, to
the effect that such modification of, addition to or elimination of such
provisions will not cause either REMIC I, REMIC II or REMIC III to (x) cease to
qualify as a REMIC or (y) be subject to an entity-level tax caused by the
Transfer of any Class R-I Certificate to a Person which is not a Permitted
Transferee, or cause a Person other than the prospective Transferee to be
subject to a REMIC-related tax caused by the Transfer of a Class R-I Certificate
to a Person which is not a Permitted Transferee.

                  A "Permitted Transferee" is any Transferee other than (i) the
United States, any State or political subdivision thereof, any possession of the
United States, or any agency or instrumentality of any of the foregoing (other
than an instrumentality which is a corporation if all of its activities are
subject to tax and, except for FHLMC, a majority of its board of directors is
not selected by such governmental unit), (ii) a foreign government, any
international organization, or any agency or instrumentality of any of the
foregoing, (iii) any organization (other than certain farmers' cooperatives
described in Section 521 of the Code) which is exempt from the tax imposed by
Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381(a)(2)(C) of the Code, and (v) any
electing large partnership under Section 775 of the Code and/or any other Person
so designated by the Trustee based upon an Opinion of Counsel that the holding
of an Ownership Interest in a Class R-I Certificate by such Person may cause the
Trust Fund or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Class R-I Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

                  A "United States Person" 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
(except, in the case of a partnership, to the extent provided in Treasury
regulations), an estate whose income from sources without the United States is
includable 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, or a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States Persons have the authority to control all substantial
decisions of the trust.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-I Certificates, but the Trustee or the
Certificate Registrar 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 Class R-I Certificates.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                 The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of REMIC I, REMIC II or REMIC III as a REMIC, without the consent of the Holders
of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

registered owner of the Percentage Interest evidenced by this Class R-II
Certificate (as specified above) in that certain beneficial ownership interest
evidenced by all the Class R-II Certificates in the Trust Fund created pursuant

the respective meanings assigned in the Agreement. This Certificate is issued
under and is subject to the terms, provisions and conditions of the Agreement,

hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 15th day of each month or, if such 15th day is not a Business Day,
the Business Day immediately following (each, a "Distribution Date"), commencing
upon the First Distribution Date specified

                                     A-24-2
<PAGE>

above, to the Person in whose name this Certificate is registered at the close
of business on the last Business Day of the month immediately preceding the
month of such distribution (the "Record Date"), in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the amount
required to be distributed to the Holders of the Class R-II Certificates on the

this Certificate at the offices of the Certificate Registrar appointed as

                  The Depositor's Mortgage Pass-Through Certificates, Series
2000-C3 (the "Certificates") are limited in right of distribution 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 Certificate Distribution
Account may be made from time to time for purposes other than, and, in certain
cases, prior to, distributions to Certificateholders, such purposes including
the reimbursement of advances made, or certain expenses incurred, with respect
to the Mortgage Loans and the payment of interest on such advances and expenses.

                  The Class R-II Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-II Certificates are
exchangeable for new Class R-II Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-II Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No transfer of any Class R-II Certificate shall be made unless
that transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction that does not require such
registration or qualification. If such a transfer of any Class R-II Certificate
(other than a transfer thereof by the Depositor or any Affiliate of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require, in order to assure compliance with such laws, receipt by
it and the Depositor of a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached as Exhibit B-1 to the
Agreement and a certificate from such Certificateholder's prospective transferee
substantially in the form attached as Exhibit B-2 to the Agreement. None of the
Depositor, the Trustee or the Certificate Registrar is obligated to register or
qualify the Class R-II Certificates under the Securities Act or any other

securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class R-II Certificate without registration or
qualification. Any Class R-II Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class R-II Certificate agrees to,
indemnify the Depositor, the Trustee and the Certificate Registrar 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 a Class R-II Certificate or any interest
therein shall be made to (A) any employee benefit plan or other retirement
arrangement, including individual retirement accounts and annuities, Keogh plans
and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested, that is subject to ERISA or Section 4975
of the Code (each, a "Plan") or (B) any Person who is directly or indirectly
purchasing the Class R-II Certificate or interest therein on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan.

                  Each Person who has or who acquires any Ownership Interest in
this Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the provisions of Section
5.02(d) of the Agreement and, if any purported Transferee shall become a Holder
of this Certificate in violation of the provisions of such Section 5.02(d), to
have irrevocably authorized the Trustee under clause (ii)(A) of such Section
5.02(d) to deliver payments to a Person other than such Person and to have
irrevocably authorized the Trustee under clause (ii)(B) of such Section 5.02(d)
to negotiate the terms of any mandatory sale and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
Each Person holding or acquiring any Ownership Interest in this Certificate must
be a Permitted Transferee and a United States Person and shall promptly notify
the Trustee of any change or impending change in its status as a Permitted
Transferee or United States Person. In connection with any proposed Transfer of
any Ownership Interest in this Certificate, the Trustee shall require delivery
to it, and shall not register the Transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit C-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, in form and substance satisfactory to the Trustee, representing and
warranting, among other things, that such Transferee is a Permitted Transferee
and a United States Person, that it is not acquiring its Ownership Interest in
this Certificate as a nominee, trustee or agent for any Person that is not a
Permitted Transferee or is not a United States Person, that for so long as it
retains its Ownership Interest in this Certificate, it will endeavor to remain a
Permitted Transferee and a United States Person, and that it has reviewed the
provisions of Section 5.02(d) of the Agreement and agrees to be bound by them.
Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed
Transferee, if the Trustee has actual knowledge that the proposed Transferee is
not a Permitted Transferee or is not a United States Person, the Trustee shall
not register the Transfer of an Ownership Interest in this Certificate to such
proposed Transferee.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any prospective Transferee to whom such Person attempts to transfer its
Ownership Interest herein and (y) not to transfer its Ownership Interest unless
it provides to the Trustee a certificate substantially in the form attached as
Exhibit C-2 to the Agreement stating that, among other things, it has no actual
knowledge that such prospective Transferee is not a Permitted Transferee or is
not a United

                                     A-24-4
<PAGE>

States Person. Each Person holding or acquiring an Ownership Interest in this
Certificate, by purchasing such Ownership Interest herein, agrees to give the
Trustee 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 such Ownership Interest, if it is, or is holding such Ownership
Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Trustee the following: (a) written notification from each Rating Agency
to the effect that the modification of, addition to or elimination of such
provisions will not cause such Rating Agency to withdraw, qualify or downgrade
its then-current rating of any Class of Certificates; and (b) an Opinion of
Counsel, in form and substance satisfactory to the Trustee and the Depositor, to
the effect that such modification of, addition to or elimination of such
provisions will not cause either REMIC I, REMIC II or REMIC III to (x) cease to
qualify as a REMIC or (y) be subject to an entity-level tax caused by the
Transfer of any Class R-II Certificate to a Person which is not a Permitted
Transferee, or cause a Person other than the prospective Transferee to be
subject to a REMIC-related tax caused by the Transfer of a Class R-II
Certificate to a Person which is not a Permitted Transferee.

                  A "Permitted Transferee" is any Transferee other than (i) the
United States, any State or political subdivision thereof, any possession of the
United States, or any agency or instrumentality of any of the foregoing (other
than an instrumentality which is a corporation if all of its activities are
subject to tax and, except for FHLMC, a majority of its board of directors is
not selected by such governmental unit), (ii) a foreign government, any
international organization, or any agency or instrumentality of any of the
foregoing, (iii) any organization (other than certain farmers' cooperatives
described in Section 521 of the Code) which is exempt from the tax imposed by
Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381(a)(2)(C) of the Code, and (v) any
electing large partnership under Section 775 of the Code and/or any other Person
so designated by the Trustee based upon an Opinion of Counsel that the holding
of an Ownership Interest in a Class R-II Certificate by such Person may cause
the Trust Fund or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Class R-II Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

                  A "United States Person" 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
(except, in the case of a partnership, to the extent provided in Treasury
regulations), an estate whose income from sources without the United States is
includable 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, or a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States Persons have the authority to control all substantial
decisions of the trust.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-II Certificates, but the Trustee or the
Certificate Registrar 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 Class R-II Certificates.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of REMIC I, REMIC II or REMIC III as a REMIC, without the consent of the Holders
of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

the respective meanings assigned in the Agreement. This Certificate is issued
under and is subject to the terms, provisions and conditions of the Agreement,
to which Agreement the Holder of this Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 15th day of each month or, if such 15th day is not a Business Day,
the Business Day immediately following (each, a "Distribution Date"), commencing
upon the First Distribution Date specified

                                     A-25-2

above, to the Person in whose name this Certificate is registered at the close
of business on the last Business Day of the month immediately preceding the
month of such distribution (the "Record Date"), in an amount equal to the
product of the Percentage Interest evidenced by this Certificate and the amount
required to be distributed to the Holders of the Class R-III Certificates on the
applicable Distribution Date pursuant to the Agreement. All distributions made
under the Agreement on any Class R-III Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto, as such name and
address appear in the Certificate Register. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the offices of the Certificate Registrar appointed as
provided in the Agreement or such other location as may be specified in such
notice.

                  The Depositor's Mortgage Pass-Through Certificates, Series
2000-C3 (the "Certificates") are limited in right of distribution 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 Certificate Distribution
Account may be made from time to time for purposes other than, and, in certain
cases, prior to, distributions to Certificateholders, such purposes including
the reimbursement of advances made, or certain expenses incurred, with respect
to the Mortgage Loans and the payment of interest on such advances and expenses.

                  The Class R-III Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-III Certificates are
exchangeable for new Class R-III Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-III Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No transfer of any Class R-III Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. If such a transfer of any Class
R-III Certificate (other than a transfer thereof by the Depositor or any
Affiliate of the Depositor) is to be made without registration under the
Securities Act, then the Trustee shall require, in order to assure compliance
with such laws, receipt by it and the Depositor of a certificate from the
Certificateholder desiring to effect such transfer substantially in the form
attached as Exhibit B-1 to the Agreement and a certificate from such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the Agreement. None of the Depositor, the Trustee or the
Certificate Registrar is obligated to register or qualify the Class R-III
Certificates

                                     A-25-3
<PAGE>

under the Securities Act or any other securities law or to take any action not
otherwise required under the Agreement to permit the transfer of any Class R-III
Certificate without registration or qualification. Any Class R-III
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class R-III Certificate agrees to, indemnify the Depositor,
the Trustee and the Certificate Registrar 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 a Class R-III Certificate or any interest
therein shall be made to (A) any employee benefit plan or other retirement
arrangement, including individual retirement accounts and annuities, Keogh plans
and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested, that is subject to ERISA or Section 4975
of the Code (each, a "Plan") or (B) any Person who is directly or indirectly
purchasing the Class R-III Certificate or interest therein on behalf of, as
named fiduciary of, as trustee of, or with assets of a Plan.

                  Each Person who has or who acquires any Ownership Interest in
this Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the provisions of Section
5.02(d) of the Agreement and, if any purported Transferee shall become a Holder
of this Certificate in violation of the provisions of such Section 5.02(d), to
have irrevocably authorized the Trustee under clause (ii)(A) of such Section
5.02(d) to deliver payments to a Person other than such Person and to have
irrevocably authorized the Trustee under clause (ii)(B) of such Section 5.02(d)
to negotiate the terms of any mandatory sale and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
Each Person holding or acquiring any Ownership Interest in this Certificate must
be a Permitted Transferee and a United States Person and shall promptly notify
the Trustee of any change or impending change in its status as a Permitted
Transferee or United States Person. In connection with any proposed Transfer of
any Ownership Interest in this Certificate, the Trustee shall require delivery
to it, and shall not register the Transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit C-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, in form and substance satisfactory to the Trustee, representing and
warranting, among other things, that such Transferee is a Permitted Transferee
and a United States Person, that it is not acquiring its Ownership Interest in
this Certificate as a nominee, trustee or agent for any Person that is not a
Permitted Transferee or is not a United States Person, that for so long as it
retains its Ownership Interest in this Certificate, it will endeavor to remain a
Permitted Transferee and a United States Person, and that it has reviewed the
provisions of Section 5.02(d) of the Agreement and agrees to be bound by them.
Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed
Transferee, if the Trustee has actual knowledge that the proposed Transferee is
not a Permitted Transferee or is not a United States Person, the Trustee shall
not register the Transfer of an Ownership Interest in this Certificate to such
proposed Transferee.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any prospective Transferee to whom such Person attempts to transfer its
Ownership Interest herein and (y) not to transfer its Ownership Interest unless
it provides to the Trustee a certificate substantially in the form attached as
Exhibit C-2 to the Agreement stating that, among other things, it has no actual
knowledge that such prospective Transferee is not a Permitted Transferee or is
not a United

                                     A-25-4
<PAGE>

States Person. Each Person holding or acquiring an Ownership Interest in this
Certificate, by purchasing such Ownership Interest herein, agrees to give the
Trustee 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 such Ownership Interest, if it is, or is holding such Ownership
Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Trustee the following: (a) written notification from each Rating Agency
to the effect that the modification of, addition to or elimination of such
provisions will not cause such Rating Agency to withdraw, qualify or downgrade
its then-current rating of any Class of Certificates; and (b) an Opinion of
Counsel, in form and substance satisfactory to the Trustee and the Depositor, to
the effect that such modification of, addition to or elimination of such
provisions will not cause either REMIC I, REMIC II or REMIC III to (x) cease to
qualify as a REMIC or (y) be subject to an entity-level tax caused by the
Transfer of any Class R-III Certificate to a Person which is not a Permitted
Transferee, or cause a Person other than the prospective Transferee to be
subject to a REMIC-related tax caused by the Transfer of a Class R-III
Certificate to a Person which is not a Permitted Transferee.

                  A "Permitted Transferee" is any Transferee other than (i) the
United States, any State or political subdivision thereof, any possession of the
United States, or any agency or instrumentality of any of the foregoing (other
than an instrumentality which is a corporation if all of its activities are
subject to tax and, except for FHLMC, a majority of its board of directors is
not selected by such governmental unit), (ii) a foreign government, any
international organization, or any agency or instrumentality of any of the
foregoing, (iii) any organization (other than certain farmers' cooperatives
described in Section 521 of the Code) which is exempt from the tax imposed by
Chapter 1 of the Code (including the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381(a)(2)(C) of the Code, and (v) any
electing large partnership under Section 775 of the Code and/or any other Person
so designated by the Trustee based upon an Opinion of Counsel that the holding
of an Ownership Interest in a Class R-III Certificate by such Person may cause
the Trust Fund or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Class R-III Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

                  A "United States Person" 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
(except, in the case of a partnership, to the extent provided in Treasury
regulations), an estate whose income from sources without the United States is
includable 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, or a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States Persons have the authority to control all substantial
decisions of the trust.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-III Certificates, but the Trustee or the
Certificate Registrar 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 Class R-III Certificates.

                  Prior to due presentment of this Certificate for registration
of transfer, the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Certificate Registrar and any agents of any of
them 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 Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar
or any such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan, Companion Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer or the
Depositor at a price determined as provided in the Agreement of all Mortgage
Loans, Companion Loans and any REO Properties remaining in the Trust Fund. The
Agreement permits, but does not require, the Depositor or the Master Servicer to
purchase from the Trust Fund all Mortgage Loans, Companion Loans and any REO
Properties remaining therein. 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 Pool at the time of
purchase being less than 1% of the aggregate Cut-off Date Principal Balance of
the Mortgage specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof, and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent thereunder and the rights of the Certificateholders
thereunder, at any time by the Depositor, the Master Servicer, the Special
Servicer, the Trustee and the Fiscal Agent with the consent of the Holders of
Certificates entitled to at least 66-2/3% of the Voting Rights allocated to the
affected Classes. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain circumstances, including any amendment necessary to maintain the status
of REMIC I, REMIC II or REMIC III as a REMIC, without the consent of the Holders
of any of the Certificates.

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

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  2000 of $________] [evidencing a _____% Percentage Interest in
                  such Class].

Dear Sirs:

         This letter is delivered to you in connection with the transfer by (the
"Transferor") to (the "Transferee") of the captioned Certificates (the
"Certificates"), pursuant to Section 5.02 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated as of December 1, 2000, among
GMAC Commercial Mortgage Securities, Inc., as Depositor, GMAC Commercial
Mortgage Corporation, as Master Servicer and Special Servicer, and LaSalle Bank
National Association., as Trustee, and ABN AMRO Bank N.V., as Fiscal Agent. All
terms used herein and not otherwise defined will have the respective meanings
set forth in the Pooling and Servicing Agreement. The Transferor hereby
certifies, represents and warrants to you, as Certificate Registrar, that:

         1. The Transferor is the lawful owner of the Certificates with the full
right to transfer the Certificates free from any and all claims and encumbrances
whatsoever.

         2. Neither the Transferor nor anyone acting on its behalf has (a)
offered, transferred, pledged, sold or otherwise disposed of the Certificates,
any interest in the Certificates or any other similar security to any person in
any manner, (b) solicited any offer to buy or accept a transfer, pledge or other
disposition of the Certificates, any interest in the Certificates or any other
similar security from any person in any manner, (c) otherwise approached or
negotiated

                                     B-1-1
<PAGE>

with respect to the Certificates, any interest in the Certificates or
any other similar security with any person in any manner, (d) made any general
solicitation with respect to the Certificates, any interest in the Certificates
or any other similar security by means of general advertising or in any other
manner, or (e) taken any other action with respect to the Certificates, any
interest in the Certificates or any other similar security, which (in the case
of any of the acts described in clauses (a) through (e) hereof) would constitute
a distribution under the Securities Act of 1933 (the "Securities Act"), or would
render the disposition of the Certificates a violation of Section 5 of the
Securities Act or any state securities laws, or would require registration or
qualification of the Certificates pursuant to the Securities Act or any state
securities laws.

         3. The Transferor and any person acting on behalf of the Transferor in
this matter reasonably believe that the Transferee is a "qualified institutional
buyer" (as that term is defined in Rule 144A ("Rule 144A") under the Securities
Act) purchasing for its own account or for the account of other qualified
institutional buyers, and has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of an
investment in the Certificates.

         4. The Transferor or a person acting on its behalf has taken reasonable
steps to ensure that the Transferee is aware that the Transferor is relying on
the exemption from the provisions of Section 5 of the Securities Act provided by
Rule 144A.

         5. The Transferor or a person acting on its behalf has furnished, or
caused to be furnished, to the Transferee all information regarding (a) the
Certificates and distributions thereon, (b) the nature, performance and
servicing of the Mortgage Loans and Loan Groups, (c) the Pooling and Servicing
Agreement, and (d) any credit enhancement mechanism associated with the
Certificates, that the Transferee has requested.

                                                     Very truly yours,

         6. If the answer to the foregoing question is "no," then in each case
where the Transferee is purchasing for an account other than its own, such
account belongs to a third party that is itself a "qualified institutional
buyer" within the meaning of Rule 144A, and the "qualified institutional buyer"
status of such third party has been established by the Transferee through one or
more of the appropriate methods contemplated by 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 Certificate 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 any
updated annual financial statements that become available on or before the date
of such purchase, promptly after they become available.

                                                     Very truly yours,

this certification is an Annex:

         1. As indicated below, the undersigned is the chief financial officer,
a person fulfilling an equivalent function, or other executive officer of the
entity purchasing the Certificates (the "Transferee") or, if the Transferee is a

investment adviser (the "Adviser").

         2. The Transferee is a "qualified institutional buyer" as defined in
Rule 144A because (i) the Transferee is an investment company registered under

         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) bank deposit notes and

Transferee's own account?

                     Yes [ ]                      No [ ]

         6. If the answer to the foregoing question is "no," then in each case
where the Transferee is purchasing for an account other than its own, such
account belongs to a third party that is itself a "qualified institutional
buyer" within the meaning of Rule 144A, and the "qualified institutional buyer"
status of such third party has been established by the Transferee through one or
more of the appropriate methods contemplated by Rule 144A.

         7. 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 FOR TRANSFERS OF

County of ________________ )

          _________________, being first duly sworn, deposes and says that:

         1. He/She is the ____________________of _______________________ (the
prospective transferee (the "Transferee") of GMAC Commercial Mortgage
Securities, Inc., Mortgage Pass-Through Certificates, Series 2000-C3, [Class
R-I] [Class R-II] [Class R-III], evidencing a % Percentage Interest in such
Class (the "Residual Certificates"), a___________________ duly organized and
validly existing under the laws of _______________, on behalf of which he/she
makes this affidavit. All capitalized terms used but not otherwise defined
herein will have the respective meanings set forth in the Pooling and Servicing
Agreement pursuant to which the Residual Certificates were issued (the "Pooling
and Servicing Agreement").

         2. The Transferee (i) is, and as of the date of transfer will be, a
"Permitted Transferee" and will endeavor to remain a "Permitted Transferee" for
so long as it holds the Residual Certificates, and (ii) is acquiring the
Residual Certificates for its own account. 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, an electing large partnership under Section 775 of the Code, 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 Transferee is aware (i) of the tax that would be imposed on
transfers of the Residual Certificates to "disqualified organizations" under the
Code that applies to all transfers of the Residual Certificates; (ii) that such
tax would be on the transferor (or, with respect to transfers to electing large
partnerships, on such partnership) 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
will be relieved of liability for the tax if the transferee furnishes to such
Person (other than transfers with respect to electing large partnerships) 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 the Residual Certificates may be a "noneconomic residual
interest" within the meaning of Treasury regulation Section 1.860E1(c) and that
the transferor of a "noneconomic residual interest" will remain liable

                                      C-1-1

<PAGE>

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

         4. The Transferee is aware of the tax imposed on a "pass-through
entity" holding the Residual 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 Transferee is aware that the Certificate Registrar will not
register any transfer of the Residual Certificates by the Transferee unless the
Transferee's transferee, or such transferee's agent, delivers to the Certificate
Registrar, among other things, an affidavit and agreement in substantially the
same form as this affidavit and agreement. The Transferee expressly agrees that
it will not consummate any such transfer if it knows or believes that any
representation contained in such affidavit and agreement is false.

         6. The Transferee consents to any additional restrictions or
arrangements that will be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Residual Certificate will only be
owned, directly or indirectly, by a Permitted Transferee.

         7. The Transferee's taxpayer identification number is ________________.

         8. The Transferee has reviewed the provisions of Section 5.02(d) of the
Pooling and Servicing Agreement, a description of which provisions is set forth
in the Residual Certificates (in particular, clause (ii)(A) of Section 5.02(d)
which authorizes the Trustee to deliver payments on the Residual Certificate to
a Person other than the Transferee and clause (ii)(B) of Section 5.02(d) which
authorizes the Trustee to negotiate a mandatory sale of the Residual
Certificates, in either case, in the event that the Transferee holds such
Residual Certificates in violation of Section 5.02(d)); and the Transferee
expressly agrees to be bound by and to comply with such provisions.

         9. No purpose of the Transferee relating to its purchase or any sale of
the Residual Certificates is or will be to impede the assessment or collection
of any tax.

         10. The Transferee hereby represents to and for the benefit of the
transferor that the Transferee intends and reasonably expects to have the
ability to pay any taxes associated with holding the Residual Certificates as
they become due, fully understanding that it may incur tax liabilities in excess
of any cash flows generated by the Residual Certificates. The Transferee has
provided financial statements or other financial information requested by the
Transferor in connection with the transfer of the Residual Certificates to
permit the Transferor to assess the financial capability of the Transferor to
pay any such taxes.

         11. The Transferee will, in connection with any transfer that it makes
of the Residual Certificates, deliver to the Certificate Registrar a
representation letter substantially in the form of Exhibit C-2 to the Pooling
and Servicing Agreement.

         12. The Transferee is a citizen or resident of the United States, a
corporation, a partnership or other entity created or organized in, or under the
laws of, the United States or any

                                      C-1-2

<PAGE>

political subdivision thereof (except, in the case of a partnership, to the
extent provided in Treasury regulations), an estate whose income from sources
without the United States is includible 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, or a trust for which a court within
the United States is able to exercise primary supervision over its
administration and for which one or more United States Persons have the
authority to control all substantial decisions of the trust.

         13. The Transferee is not acquiring the Residual Certificates with
"plan assets" of any plan subject to Title I of ERISA or Section 4975 of the
Code.

         IN WITNESS WHEREOF, the Transferee has caused this instrument to be
executed on its behalf, pursuant to the authority of its Board of Directors, by
its ___________ and its corporate seal to be hereunto attached, attested by its
[Assistant] Secretary, this day of, __________________________,____________.

                 GMAC Mortgage Pass-Through Certificates Series 2000-C3

         Re:     GMAC Commercial Mortgage Securities, Inc., Mortgage
                 Pass-Through Certificates, Series 2000-C3 (the "Certificates")

Dear Sirs:

         This letter is delivered to you in connection with the transfer by
____________(the "Transferor") to_____________(the "Transferee") of [Class R-I]
[Class R-II] [Class R-III] Certificates evidencing a ____% Percentage Interest
in such Class (the "Residual Certificates"). The Certificates, including the
Residual Certificates, were issued pursuant to the Pooling and Servicing
Agreement, dated as of December 1, 2000 (the "Pooling and Servicing Agreement"),
among GMAC Commercial Mortgage Securities, Inc., as Depositor, GMAC Commercial
Mortgage Corporation, as Master Servicer and Special Servicer, and LaSalle Bank
National Association, as Trustee and ABN AMRO Bank N.V., as Fiscal Agent. All
capitalized terms used but not otherwise defined herein will have the respective
meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby
certifies, represents and warrants to you, as Certificate Registrar, that:

         1. No purpose of the Transferor relating to the transfer of the
Residual Certificates by the Transferor to the Transferee is or will be to
impede the assessment or collection of any tax.

         2. The Transferor understands that the Transferee has delivered to you
a Transfer Affidavit and Agreement in the form attached to the Pooling and
Servicing Agreement. The Transferor does not know or believe that any
representation contained therein is false.

         3. The Transferor at the time of this transfer either (i) (A) has
conducted a reasonable investigation of the financial condition of the
Transferee as contemplated by Treasury

                                      C-2-1

<PAGE>

regulation Section 1.860E-1(c)(4)(i) and, as a result of that investigation, the
Transferor has determined that the Transferee has historically paid its debts as
they became due and has found no significant evidence to indicate that the
Transferee will not continue to pay its debts as they become due in the future,
and (B) has determined that the present value of the anticipated tax liabilities
associated with the holding of the Residual Certificate does not exceed the sum
of (1) the present value of any consideration given to the Transferee to acquire
the Certificate, (2) the present value of the expected future distributions on
the Certificate, and (3) the present value of the anticipated tax savings
associated with holding the Certificate as the REMIC generates losses (having
made such determination by (I) assuming that the Transferee pays tax at a rate
equal to the highest rate of tax specified in Section 11(b)(1) of the Internal
Revenue Code ("Code"), and (II) utilizing a discount rate for present valuations
equal to the applicable Federal rate prescribed by Section 1274(d) of the Code
compounded semi-annually (or a lower discount rate based on the Transferee
having demonstrated that it regularly borrows, in the course of its trade or
business, substantial funds at such lower rate from unrelated third parties)),
or (ii) based on an adequate review of the relevant facts and circumstances,
neither knows nor should know that the Transferee would be unwilling or unable
to pay any taxes due on its share of the taxable income of the REMIC.

         4. The Transferor understands that the transfer of the Residual
Certificates may not be respected for United States income tax purposes (and the
Transferor may continue to be liable for United States income taxes associated
therewith) at least one of the tests as described above in Paragraph 3(i) and
3(ii) has been met as to any transfer.

                                                     Very truly yours,

              MORTGAGE ASSET SCHEDULE TO UCC-1 FINANCING STATEMENT

         METHODOLOGY TO NORMALIZE NET OPERATING INCOME AND DEBT SERVICE COVERAGE

o        GMAC Commercial Mortgage Corporation ("GMACCM") applies the methodology
         presented below to arrive at a servicer adjusted or "Normalized" Net
         Operating Income ("NOI"). The items described below highlight some of
         the major categories requiring adjustment. There may, however, be
         others, and GMACCM will use its market knowledge and discretion in
         making and sufficiently footnoting the necessary adjustments.

o        GMACCM chooses to use the actual management fee stated in the financial
         statement.

o        Where they are clearly identifiable, GMACCM will remove any capital
         expense from any above the line categories (such as extraordinary
         repairs and maintenance) and put them below the line in the capital
         expense comment section.

o        Replacement reserves, tenant improvement and leasing commission
         reserves will be treated as above the line expenses. A determination
         will be made whether there have been credits for the disbursements from
         a reserve and that expenses are not overstated due to exclusion of
         credits.

o        Property taxes should be the annual amount due, excluding any
         delinquent taxes or credits from prior years which would cause the
         number to be higher or lower. The amount for property taxes will be
         adjusted if the period under analysis is less than one year.

o        GMAC Commercial Mortgage will exclude non-recurring, extraordinary
         income. For example, a tax refund, lease buyout or income received for
         a period other than the year in question should be adjusted. If past
         due rent for a prior year was paid and recorded in the current year,
         GMACCM would back it out and footnote it accordingly. Care will be used
         when reflecting percentage/overage rents to ensure that it relates to
         the appropriate period and that the numbers are supported by tenant
         sales information.

o        GMAC Commercial Mortgage will remove any items not pertaining to the
         operation of the property such as, fees for closing the loan
         restructure, a distribution to owners or a charitable contribution.

o        When necessary, income and expenses will be analyzed by looking at
         variances by category. Unusual income and expense items will be
         researched. If there are significant variances, inquiries to the
         borrower will be made. Appropriate adjustments will be made and
         footnotes provided to clearly explain the situation.

                                       F-1

<PAGE>

o        The debt service should be an actual amount the borrower paid per the
         servicing records for the period associated with the operating
         statement. If GMACCM does not have a full year of payments, it will use
         the principal and interest constant in the case of a fixed rate loan
         and, in the case of an adjustable rate loan, will estimate a full year
         amount from the payment history information available.
