          THIS POOLING AND SERVICING AGREEMENT, dated as of December 1, 1995, is
hereby executed by and among CS FIRST BOSTON MORTGAGE SECURITIES CORP., a
Delaware corporation, as depositor (the "Depositor"), WELLS FARGO BANK, NATIONAL
ASSOCIATION, a national banking association, as master servicer (in such
capacity, the "Master Servicer") and as initial special servicer (in such
capacity, the "Special Servicer"), LASALLE NATIONAL BANK, a nationally chartered
bank, as trustee for the benefit of the Certificateholders (the "Trustee") and
ABN AMRO BANK N.V., as fiscal agent, (in such capacity, the "Fiscal Agent").

                             PRELIMINARY STATEMENT

          The Depositor intends to sell commercial mortgage pass-through
certificates to be issued hereunder in multiple classes which in the aggregate
will evidence the entire beneficial ownership interest in the Trust Fund
consisting primarily of the Mortgage Loans.  Wells Fargo Bank, National
Association, as Seller (in such capacity "Seller") has sold the Mortgage Loans
to the Depositor and the Depositor is the owner of the Mortgage Loans and the
other property being conveyed by it to the Trustee in accordance with this
Agreement.  The Depositor has duly authorized the execution and delivery of this
Agreement to provide for the conveyance to the Trustee of the Trust Fund.

          As provided herein, the Depositor will make an election to treat the
assets consisting of the Mortgage Loans and certain other related assets
described herein as a "real estate mortgage investment conduit" for federal
income tax purposes and such pool of assets will be designated as "Tier 1
REMIC."  Uncertificated Tier 1 REMIC Regular Interests will be the "regular
interests" in Tier 1 REMIC and the Class R-I Certificate will be the "residual
interest" in Tier 1 REMIC for federal income tax purposes.

          The Depositor will make an election to treat the pool of assets
consisting of the Uncertificated Tier 1 REMIC Regular Interests as a "real
estate mortgage investment conduit" for federal income tax purposes and such
pool of assets will be designated as "Tier 2 REMIC."

          The Class A-1, Class A-2, Class A-X, Class B, Class C, Class D, Class
E, Class F and Class G Certificates will represent "regular interests" in the
Tier 2 REMIC and the Class R-II Certificate will represent the "residual
interest" in the Tier 2 REMIC for federal income tax purposes.

          All covenants and agreements made by the Depositor herein are for the
benefit and security of the Certificateholders and the Trustee.  The Depositor
is entering into this Agreement, and the Trustee is accepting the trust created
hereby, for good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged.  The principal balance of the Mortgage Loans as
of the Cut-off Date is $243,880,562.

          The following table sets forth the designation and aggregate Initial
Certificate Principal Balance for each Class of Certificates:

              (viii) the original lender's title policy and all riders thereto,
     or, in the event such original title policy has not been received from the
     insurer, any one of an original title binder, an original preliminary title
     report or an original title commitment, or a copy thereof certified by the
     title company, and the escrow closing instructions specifying acceptability
     of such document, with the original policy of title insurance to be
     delivered promptly following receipt thereof from the applicable insurer,
     but in any case not later than 45 days after the Delivery Date;

                (ix) the original of any guaranty relating to the Mortgage Loan;

                 (x) if separate from the Mortgage, the original security
     agreement or comparable instrument, an original assignment thereof to the
     Trustee for the benefit of the Certificateholders; and

                (xi) any and all amendments, modifications and supplements to,
     and waivers related to, any of the foregoing.

               Notwithstanding the foregoing, in the event that, in connection
with any Mortgage Loan the Depositor cannot deliver an original recorded
counterpart of any of the documents required to be delivered pursuant to clauses
(ii), (iv) or (v) above with evidence of recording thereon concurrently with the
execution and delivery hereof, the Depositor shall deliver, or cause the Seller
to deliver, to the Trustee a duplicate original or true copy of such document
certified by the Seller or the applicable public recording office to be a true
and complete duplicate original or copy of the original thereof submitted for
recording. The Depositor shall promptly deliver, or cause the Seller to deliver,
to the Trustee (A) such original document, with evidence of recording indicated
thereon, or a photocopy of such document certified by the appropriate county
recorder's office to be a true and complete copy of the original thereof, upon
receipt thereof from the public recording official or from Seller, and (B) upon
discovery of any defect or omission in the deliveries of any of items (ii), (iv)
or (v) above with respect to any Mortgage Loan, a correct and complete document
or instrument meeting the requirements of such item or a certified copy thereof,
certified by the relevant recording office, but in no event shall any such
delivery be made later than 120 days following the Delivery Date. From time to
time the Master Servicer or the Special Servicer may forward or cause to be
forwarded to the Trustee for the benefit of the Certificateholders additional
original documents evidencing an assumption or modification of a Mortgage Loan.

               Notwithstanding the foregoing, in the event that the Seller
cannot deliver to the Trustee any UCC-2 or UCC-3 Assignment with the filing
information of the UCC-1 Financing Statement being assigned, solely because of a
delay caused by the public filing

                                       36
<PAGE>
 
office where such UCC-1 Financing Statement had been delivered for filing, the
Depositor shall deliver or cause the related Seller to deliver to the Trustee a
photocopy of such UCC-2 or UCC-3 Financing Statement with the filing information
left blank.  The Depositor shall cause the Seller, promptly upon receipt of the
applicable filing information of the UCC-1 Financing Statement being so
assigned, to deliver to the Master Servicer the original UCC-2 or UCC-3
Assignment with all appropriate filing information set forth thereon.  In the
event that the original UCC-2 or UCC-3 Assignment with all appropriate filing
information set forth thereon is not received within 120 days of the Delivery
Date, the Depositor shall cooperate with the Master Servicer in the Master
Servicer's efforts to cure or correct any such defect (including, without
limitation, by executing, or causing the Seller to execute, one or more
substitute assignments or other instruments necessary or desirable to effectuate
such cure or correction).

               The Trustee shall, at the expense of the Seller, promptly record
or file, as applicable, in the appropriate public office for real property
records or other public office each original assignment (including any
assignments relating to any Replacement Mortgage Loans) referred to in (iii),
(vi) and (vii) above with respect to each Mortgaged Property. The Trustee shall
give notice to the Master Servicer of each original assignment with evidence of
recording or filing indicated thereon and a photocopy thereof certified by the
appropriate county recorder's office or UCC filing office to be a true and
complete copy of the original thereof, upon receipt thereof from the public
recording or filing official. The Master Servicer, at the expense of the Seller,
shall use its best efforts for each Mortgage Loan to obtain updated ALTA
lender's title insurance policy insuring the Trustee (for the benefit of the
Certificateholders) as to the first priority lien of the Mortgage in the
original principal amount of the Mortgage Loan. If any assignment is returned
unrecorded to the Trustee because of any defect therein, the Trustee shall use
its best efforts to cure or correct, or to cause the Seller to cure or correct,
such defect and cause such assignment to be recorded or filed in accordance with
this paragraph or, if the Trustee gives notice to the Seller that such defect
cannot be so cured, the Trustee shall cause the Seller, within 90 days of the
receipt of such notice to either (1) substitute a Replacement Mortgage Loan or
Loans, without recourse, for the Mortgage Loan as to which the deficiency
exists, which substitution shall be accomplished in the manner and subject to
the conditions set forth in Section 2.03(b), or (2) purchase such Mortgage Loan
at the Purchase Price therefor in accordance with the Mortgage Loan Purchase
Agreement. The Depositor shall cooperate with the Trustee in the Trustee's
efforts to cure or correct any such defect (including, without limitation, by
executing one or more substitute assignments or other instruments necessary or
desirable to effectuate such cure or correction). The Trustee shall give written
notice to the Rating Agencies of the occurrence of any substitution or purchase
required under this paragraph.

               In the case of Mortgage Loans that have been prepaid in full
after the Cut-off Date and prior to the Delivery Date, the Depositor, in lieu of
delivering the above documents to the Trustee, will remit to the Master Servicer
for deposit in the related Collection Account the amount with respect to such
payment that is required to be deposited in the Collection Account pursuant to
Section 3.08 and will provide the Trustee with written notice of such
prepayment.

               SECTION 2.02.  ACCEPTANCE BY TRUSTEE.
                              --------------------- 

               The Trustee will hold (i) the documents referred to in Section
2.01 above and the other documents constituting a part of the Trustee Mortgage
Files delivered to it and (ii) the Uncertificated Tier 1 REMIC Regular
Interests, in each case, in trust for the use and benefit of all present and
future Certificateholders.

               Upon execution and delivery of this Agreement in respect of the
Initial Certification, and within 60 days after the execution and delivery of
this Agreement in respect of the Final Certification, the Trustee shall examine
the Trustee Mortgage Files in its possession, and shall deliver to the
Depositor, the Master Servicer and the Special Servicer a certification (the
"Initial Certification" and the "Final Certification", respectively, in the
respective forms set forth as Exhibit I and Exhibit J hereto) to the effect
                              ---------     ---------                      
that, in the case of the Initial Certification, subject to the further review
provided for herein, as to each Mortgage Loan listed in the Mortgage Loan
Schedule, except as may be specified in a list of exceptions attached thereto
and in the case of the Final Certification to the effect that: (a) all documents
required to be included in the Trustee Mortgage File pursuant to this Agreement
are in its possession, (b) such documents have been reviewed by it and have not
been materially mutilated, damaged, defaced, torn or otherwise physically
altered, and such documents relate to such Mortgage Loan, (c) based on its
examination and only as to the foregoing documents, the information set forth in
items (i) and (ii) of the definition of Mortgage Loan Schedule respecting such
Mortgage Loan accurately reflects the information contained in the documents in
the Trustee Mortgage File and (d) each Mortgage Note has been endorsed and each
assignment of Mortgage has been delivered as provided in Section 2.01 hereof.
The Trustee shall deliver to the Master Servicer, the Special Servicer and the
Seller (as to its respective Mortgage Loans only), a copy of such Final
Certification.  In giving the certifications required above, the Trustee shall
be under no obligation or duty to inspect, review or examine any such documents,
instruments, securities or other papers to determine whether they or the
signatures thereon are genuine, enforceable or appropriate for their represented
purposes, or that they are other than what they purport to be on their face, or
to determine whether any Trustee Mortgage File should include any assumption
agreement, modification agreement, written assurance or substitution agreement.

               If, in the course of such review, the Trustee finds any document
constituting a part of a Trustee Mortgage File which does not meet the
requirements of clauses (a) through (d) in the preceding paragraph, the Trustee
shall promptly notify the Seller, the Master Servicer, and the Depositor in
writing and shall request the Seller to correct or cure such defect in the
manner and within the period or periods set forth in the Mortgage Loan Purchase
Agreement and absent such correction or cure, and, in the case of a defect which
results from a failure to meet one or more requirements of clauses (a) through
(c) in the preceding paragraph, such defect materially and adversely affects the
value of the related Mortgage Loan or the interest of the Trustee in the related
Mortgage Loan, or in any event in the case of a defect under (d), the Trustee
shall request the Seller, at the Seller's election, to, and the Seller shall
promptly upon such request, either (i) substitute for the related Mortgage Loan,
without recourse, a Replacement Mortgage Loan or Loans, which substitution shall
be accomplished in the manner and subject to the conditions set forth in Section
2.03; or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase
Price

                                       38
<PAGE>
 
therefor in accordance with the Mortgage Loan Purchase Agreement.  The Purchase
Price for any such Mortgage Loan shall be paid to the Master Servicer and
deposited by the Master Servicer in the Collection Account.  Upon receipt by the
Trustee of written notification of deposit of the Purchase Price or other amount
required of the Seller, signed by a Servicing Officer of the Master Servicer
(which notification shall include a statement as to the accuracy of the
calculation of the Purchase Price or other required deposit), the Trustee shall
release the related Trustee Mortgage File to the Seller and the Trustee and the
Depositor shall execute and deliver such instruments of transfer or assignment
in the forms presented to it, in each case without recourse, as shall be
necessary to vest in the Seller, or its designee, title (to the extent that such
title was transferred to the Depositor or the Trustee) to any Mortgage Loan
released pursuant hereto.

               The Trustee or its authorized agents shall retain possession and
custody of each Trustee Mortgage File in accordance with and subject to the
terms and conditions set forth herein.

               SECTION 2.03.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE 
                              ------------------------------------------------
                              SELLER TO THE MORTGAGE LOANS.
                              ---------------------------- 

               (a)   The Depositor hereby assigns to the Trustee for the benefit
of the Certificateholders the benefit of the representations, warranties and
covenants of the Mortgage Loan Purchase Agreement, including the representations
and warranties as to the Mortgage Loans specified in Schedule II to such 
Mortgage Loan Purchase Agreement (and attached as Exhibit T hereto) and the 
                                                  ---------       
obligation of the Seller to cure or correct any defective Mortgage Loans or
substitute one or more Replacement Mortgage Loans for or repurchase defective
Mortgage Loans, under certain circumstances, as provided in Section 7 of the
Mortgage Loan Purchase Agreement (subject to the limitations set forth therein)
and the Seller has acknowledged such assignment. The Depositor hereby represents
and warrants to the Trustee with respect to each Mortgage Loan that it has taken
no action to impair or encumber the title to each Mortgage Loan, or to subject
any such Mortgage Loan to any offsets, defenses or counterclaims during the
Depositor's ownership thereof.

               (b)   It is understood and agreed that the representations and
warranties set forth in this Section 2.03 (including those assigned to the
Trustee by the Depositor pursuant to Section 2.03(a) hereof) shall survive
delivery of the respective Trustee Mortgage Files to the Trustee.  Upon
discovery by the Depositor, the Master Servicer, the Special Servicer or the
Trustee (or upon written notice thereof from any Certificateholder expressly
identifying a breach) of a breach or breaches of any of the representations and
warranties set forth in the Mortgage Loan Purchase Agreement that materially and
adversely affects the value of the related Mortgage Loan or the interest of the
Trustee on behalf of the Certificateholders in the related Mortgage Loan, the
party discovering such breach or breaches shall give prompt written notice to
the other parties and the Rating Agencies.  The Master Servicer shall promptly
notify the Seller of such breach and request that such Person correct or cure
such breach in accordance with the Mortgage Loan Purchase Agreement, within 90
days from the date the Seller was notified in writing of such breach (provided
that if the Seller certifies to the Trustee and the Master Servicer that (i)
such defect is not reasonably susceptible of correction or cure within such 90-
day period and is susceptible of correction or cure within

                                       39
<PAGE>
 
an additional 90-day period, (ii) such defect does not cause the related
Mortgage Loan to fail to be a "qualified mortgage" or "qualified replacement
mortgage" within the meaning of Section 860G of the Code and (iii) the Seller is
diligently attempting to correct or cure such defect, then the Seller shall have
an additional period of 90 days in which to correct or cure such defect) and,
upon the failure of the Seller to correct or cure such breach within such period
or periods or the earlier certification of the Seller to the Trustee and the
Master Servicer that any such breach cannot be reasonably cured or corrected,
then, if such breach is not a breach of the representation and warranty of the
Depositor set forth in the last sentence of the first paragraph of Section
2.03(a) hereof, the Trustee shall cause the Seller to either (i) substitute for
such Mortgage Loan, without recourse, a Replacement Mortgage Loan or Loans,
which substitution shall be accomplished in the manner and subject to the
conditions set forth in this Section 2.03(b), or (ii) purchase the affected
Mortgage Loan at the Purchase Price therefor in accordance with the Mortgage
Loan Purchase Agreement; provided, however, that the Seller will be permitted to
                         --------  -------                                      
deliver a Replacement Mortgage Loan only to the extent that the Principal
Balance of such Replacement Mortgage Loan, together with the aggregate
outstanding Principal Balance of all Replacement Mortgage Loans previously
substituted, does not exceed 25% of the aggregate outstanding Principal Balance
of all Mortgage Loans; and provided, further, that the Seller may substitute for
                           --------  -------                                    
such Mortgage Loan only until two years after the start-up day for the REMICs.

               As to any Replacement Mortgage Loan or Loans, the Master Servicer
shall cause the Seller to deliver to the Trustee for such Replacement Mortgage
Loan or Loans, the Mortgage Note, the Mortgage, the related assignment of the
Mortgage, and such other documents and agreements as are required by Section
2.01, with the Mortgage Note endorsed as required by Section 2.01.  No
substitution may be made in any calendar month after the Determination Date for
such month.  Monthly payments due with respect to Replacement 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 Seller 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 Seller shall be
entitled to retain all amounts received in respect of such Deleted Mortgage
Loan.

               The Master Servicer shall amend or cause to be amended the
Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan and
the substitution of the Replacement Mortgage Loan or Loans and upon such
amendment the Master Servicer shall deliver or cause to be delivered such
amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the
Replacement Mortgage Loan or Loans shall be subject to the terms of this
Agreement in all respects. Upon receipt of the Trustee Mortgage File pertaining
to any Replacement Mortgage Loans, the Trustee shall release the Trustee
Mortgage File relating to such Deleted Mortgage Loan to the Seller, and the
Trustee (and the Depositor, if necessary) shall execute and deliver such
instruments of transfer or assignment in the form presented to it, in each case
without recourse, as shall be necessary to vest title (to the extent that such
title was transferred to the Trustee or the Depositor) in the Seller or its
designee to any Deleted Mortgage Loan substituted for pursuant to this Section
2.03.

                                       40
<PAGE>
 
               In any month in which the Seller substitutes one or more
Replacement Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer will determine the amount (if any) by which the aggregate Principal
Balance of all such Replacement Mortgage Loans as of the date of substitution is
less than the aggregate Principal Balance of all such Deleted Mortgage Loans (in
each case after application of scheduled principal portion of the monthly
payments received in the month of substitution). The Depositor shall cause the
Seller to deposit the amount of such shortage into the Collection Account in the
month of substitution pursuant to Section 3.08, without any reimbursement
thereof. In addition, the Depositor shall cause the Seller to deposit into the
Collection Account, together with such shortage, if any, an amount equal to
interest on the Deleted Mortgage Loans at a rate equal to the sum of the
applicable Mortgage Interest Rate from the Due Date as to which interest was
last paid up to the Due Date next succeeding such substitution together with the
amount of unreimbursed Property Protection Advances, amounts required to be paid
to the Special Servicer but remaining unpaid or unreimbursed pursuant to Section
3.12(f), and interest on unreimbursed Advances with respect to such Deleted
Mortgage Loans at the Advance Rate. The Depositor shall cause the Seller, in the
case of the Mortgage Loans, to give notice in writing (accompanied by an
Officer's Certificate as to the calculation of such shortage) to the Trustee and
the Master Servicer of such event.

               Upon the discovery of any party hereto of a breach or breaches of
any of the representations and warranties set forth herein by the Depositor that
materially and adversely affects the value of the related Mortgage Loan or the
interest of the Trustee on behalf of the Certificateholders in the related
Mortgage Loan, the party discovering such breach or breaches shall give prompt
written notice to the other parties hereto and to the Rating Agencies. The
Depositor shall either correct or cure such breach in the same time and manner
as the Seller is required to cure breaches as set forth in the Mortgage Loan
Purchase Agreement and as set forth above. In the event the Depositor cannot
cure or correct such breach or breaches as provided above, the Depositor shall
either substitute or purchase such Mortgage Loan or Loans in the same time,
manner, terms and conditions as the Seller is required to substitute or
repurchase Mortgage Loans as set forth in the Mortgage Loan Purchase Agreement
and as set forth above.

               If the Seller or the Depositor, as the case may be, shall have
repurchased a Mortgage Loan, upon receipt by the Trustee of written notification
(or a request for release in the form of Exhibit K attached hereto) of the
                                         ---------                        
deposit of the Purchase Price signed by a Servicing Officer, the Trustee shall
release the related Trustee Mortgage File to such Person and the Trustee (and
the Depositor, if necessary) shall execute and deliver the related instruments
of transfer or assignment, in the form presented to it, in each case without
recourse, as shall be necessary to transfer title (to the extent that such title
was transferred to the Trustee or the Depositor) from the Trustee and vest title
in the Seller or the Depositor, as the case may be, or the designee of the
Seller or the Depositor, as the case may be, to any Mortgage Loan purchased
pursuant to this Section 2.03.  It is understood and agreed that the obligation
under the Mortgage Loan Purchase Agreement and this Section 2.03 to repurchase
or substitute any Mortgage Loan as to which such breach has occurred and is
continuing shall constitute the sole and exclusive obligation of the Seller and
Depositor in respect thereof.

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

               (a)  The Master Servicer and the Special Servicer each hereby
represents and warrants to the Depositor, the Fiscal Agent and the Trustee that,
as of the Delivery Date:

                    (i)  it is duly organized, validly existing and in good

     or is otherwise in compliance with applicable state law in any state in
     which it has not obtained any such qualification and, in any event, is in
     compliance with the doing business laws of any such state, in each case to
     the extent necessary to ensure the enforceability of each such Mortgage
     Loan and to perform the servicing of the Mortgage Loans or any Specially
     Serviced Mortgage Loans in accordance with the terms of this Agreement,
     except where the failure to so qualify or comply would not adversely affect
     the Master Servicer's or the Special Servicer's ability to perform its
     obligations hereunder in accordance with the terms of this Agreement;

                   (ii)  it has the full corporate power and corporate authority

     Servicer, enforceable against it in accordance with its terms, subject to
     applicable bankruptcy, reorganization, insolvency, receivership, moratorium
     and other laws of general applicability relating to or affecting the
     enforcement of creditors rights generally and affecting enforcement of

     proceeding in equity or at law);

                  (iii)  the execution and delivery of this Agreement by it, the
     servicing of the Mortgage Loans by it hereunder, the consummation by it of
     the transactions herein contemplated, and the fulfillment of or compliance
     with the terms hereof, by it are all in the ordinary course of its business

     and adversely affect, (A) its ability to perform its obligations under this
     Agreement or (B) its business, operations, financial condition, properties
     or assets, taken as a whole;

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

                    (v)  to its knowledge, no certificate of an officer or

     the Trustee and prepared by it in connection with this Agreement and the
     transactions contemplated hereby contains any untrue statement of a
     material fact or omits to state a material fact necessary to make the
     information, certificate, statement or report not misleading; provided that
     nothing in this Agreement shall be deemed to require it to confirm,
     represent or warrant the truth or accuracy of (or to be liable or
     responsible for) any other person's information or report utilized in any
     communication from it; and

                   (vi)  no consent, approval, authorization or order of any
     court or governmental agency or body is required for the execution,
     delivery and performance by it, or compliance by it with, this Agreement,

     consent, approval, authorization or order is required, it has obtained the
     same or will obtain the same prior to the time necessary to perform its
     obligations under this Agreement, and, except to the extent in the case of
     performance, that its failure to be qualified as a foreign corporation or

     of its obligations hereunder.

               (b)  The Trustee hereby represents and warrants to the Depositor,
the Master Servicer, and the Special Servicer that, as of the Delivery Date:

     good standing as a banking corporation under the laws of the United States,
     is duly qualified to do business as a foreign corporation and is in good
     standing under the laws of each jurisdiction in which the performance of
     its duties under this Agreement would require such qualification;

                   (ii)  the Trustee has the full power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement, and has duly authorized by

     Trustee, the consummation by the Trustee of any other of the transactions
     herein contemplated, and the fulfillment of or compliance with the terms
     hereof, by the Trustee are in the ordinary course of business of the
     Trustee and will not (1) result in a breach of any term or provision of the

     adversely affects, or, to the Trustee's knowledge could in the future
     materially and adversely affect, (A) the ability of the Trustee to perform

     transactions contemplated hereby contains any untrue statement of a
     material fact or omits to state a material fact necessary to make the
     information, certificate, statement or report not misleading, provided that
     nothing in this Agreement shall be deemed to require the Trustee to
     confirm, represent or warrant the truth or accuracy of (or to be liable or
     responsible for) any other person's information or report utilized in any
     communication from the Trustee; and

                   (vi)  no consent, approval, authorization or order of any

               (c)  The Fiscal Agent hereby represents and warrants to the

     Fiscal Agent, the consummation by the Fiscal Agent of any other of the
     transactions herein contemplated, and the fulfillment of or compliance with
     the terms hereof, by the Fiscal Agent are in the ordinary course of

                   (iv)  no litigation is pending or, to the Fiscal Agent's
     knowledge, threatened, against the Fiscal Agent that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement or the ability of the Fiscal Agent to perform any of its other
     obligations hereunder in accordance with the terms hereof;

                    (v)  no certificate of an officer or statement furnished in
     writing or written report delivered by the Fiscal Agent to the Depositor

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

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

               The Trustee acknowledges the assignment to it of the Mortgage
Loans and the Depositor's interest in the Mortgage Loan Purchase Agreement,
together with the assignment to it of the Uncertificated Tier 1 REMIC Regular
Interests, receipt of which is hereby acknowledged subject to the Trustee's
review as provided in Section 2.02 hereof. The Trustee acknowledges receipt of
notice that a security interest has been granted in the Uncertificated Tier 1
REMIC Regular Interests pursuant to Section 11.04 hereof. The rights of the
Uncertificated Tier 1 REMIC Regular Interests and the Holders of the Class R-I
Certificates to receive distributions from the proceeds of the Tier 1 REMIC and
all ownership interests of the Holders of Classes of Certificates shall be as
set forth in this Agreement.

               Concurrently with the assignment and delivery to the Trustee of
the Uncertificated Tier 1 Regular Interests and in exchange therefor, the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed the

                                       46

Certificates to receive distributions from the proceeds of the Tier 2 REMIC and
all ownership interests of the Holders of such Certificates in such
distributions shall be as set forth in this Agreement.

               SECTION 2.06.  REMIC PROVISIONS.
                              ---------------- 

               (a)  The Depositor hereby elects, authorizes and directs the
Trustee, to treat and account for the Tier 1 REMIC and Tier 2 REMIC as separate
REMICs under the Code. The Delivery Date is hereby designated as the "startup
day" of each of the REMICs within the meaning of Section 860G(a)(9) of the Code.

               The "regular interests" in Tier 1 REMIC within the meaning of
Section 860G of the Code shall consist of Uncertificated Tier 1 REMIC Regular
Interest and the Class R-I Certificate will be the "residual interest" in Tier 1
REMIC within the meaning of Section 860G of the Code.

               The "regular interests" in Tier 2 REMIC within the meaning of
Section 860G of the Code shall consist of the Class A-1, Class A-2, Class A-X,
Class B, Class C, Class D, Class E, Class F, and Class G Certificates. Class R-
II Certificates will be the "residual interest" in Tier 2 REMIC within the
meaning of Section 860G of the Code.

               The Maturity Date shall be the Final Rated Distribution Date.

               (b)   Each Holder of a Class R Certificate shall act as the "tax
matters person" within the meaning of the REMIC Provisions and Section
6231(a)(7) of the Code for the respective REMIC. By its acceptance of a Class R
Certificate, each Holder shall be deemed to have agreed to such appointment and
shall be deemed to have consented to the appointment of the Trustee as agent to
act on behalf of the REMICs pursuant to the specific duties set forth herein.

               (c)   In the event that any unindemnified federal, state or local
tax is imposed, including without limitation, taxes imposed on a "prohibited
transaction" of a REMIC as defined in Section 860F of the Code, such tax shall
be charged (i) if based on net income from foreclosure of REO Property, out of
the related proceeds or (ii) if based not on such income, then against amounts
otherwise available for distribution on the respective Class R Certificate and
then against amounts otherwise available for distribution to the Regular
Certificateholders or on the Uncertificated Tier 1 REMIC Regular Interests, as
appropriate, in accordance with the provisions set forth in Sections 4.02 and
4.03, respectively. The Trustee shall promptly deposit in the Collection Account
any amount of "prohibited transaction" tax that results from a breach of the
Trustee's duties under this Agreement due to its negligence or willful
misconduct. The Master Servicer or the Special Servicer shall promptly deposit
in the Collection Account any amount of "prohibited transaction" tax that
results from a breach of such Person's respective duties under this Agreement
due to its negligence or willful misconduct.

                                       47
<PAGE>
 
               (d)   The Trustee shall, for federal income tax purposes,
maintain books and records with respect to each of the REMICs on a calendar year
and accrual basis, or as otherwise may be required by the REMIC Provisions.

               (e)   Following the Delivery Date, neither the Trustee nor the
Fiscal Agent nor the Master Servicer nor the Special Servicer, as applicable,
shall accept any contributions of assets (other than Advances) to the Trust Fund
unless the Trustee, Master Servicer or the Special Servicer, as applicable,
shall have received an Opinion of Counsel (at the expense of such Person seeking
to make such contribution) to the effect that the inclusion of such assets in
the Trust Fund will not cause the Tier 1 REMIC or Tier 2 REMIC to fail to
qualify as a REMIC at any time that any Certificates are outstanding or subject
either to any unindemnified tax under the REMIC Provisions or other applicable
provisions of federal, state and local law.

               (f)   Neither the Trustee nor the Master Servicer nor the Special
Servicer nor the Fiscal Agent, as applicable, shall enter into any arrangement
by which any of the REMICs will receive a fee or other compensation for services
nor permit any REMIC to receive any income from assets other than "qualified
mortgages" or "permitted investments" as defined in Section 860G(a)(3) and (4)
of the Code.

               (g)  The Trustee shall act as agent on behalf of the tax matters
person of each of the REMICs and in such capacity the Trustee shall: (i)
prepare, sign and file, or cause to be prepared, signed and filed, federal and
state tax returns for each REMIC when and as required by the REMIC Provisions
and other applicable federal income tax laws as the direct representative of
each REMIC in compliance with the Code and shall provide copies of such returns
as required by the Code; (ii) make elections, on behalf of each REMIC, each to
be treated as a REMIC on the federal tax return of each REMIC for the first
taxable year thereof, in accordance with the REMIC Provisions; and (iii) prepare
and forward, or cause to be prepared and forwarded, to the Certificateholders
and to any governmental taxing authority all information reports as and when
required to be provided to them in accordance with the REMIC Provisions. The
expenses of preparing and filing such returns shall be borne by the Trustee. The
Depositor shall provide on a prompt and timely basis to the Trustee or its
designee such information with respect to each of the REMICs as is in its
possession and reasonably required or requested by the Trustee to enable it to
perform its obligations under this subsection. In its capacity as agent on
behalf of the tax matters person, the Trustee shall also: (A) represent each
REMIC in any audit, controversy or judicial proceeding relating to a
governmental taxing authority and (B) cause to be paid solely from the sources
provided herein the amount of any taxes imposed on either REMIC when and as the
same shall be due and payable (but such obligation shall not prevent the Trustee
or any other appropriate Person from contesting any such tax in appropriate
proceedings and shall not prevent the Trustee from withholding payment of such
tax, if permitted by law, pending the outcome of such proceedings).

               (h)  The Trustee, the Depositor and each Holder of a Class R
Certificate shall take all actions and cause the Trust Fund to take all actions
necessary to create and maintain the status of the respective REMICs as REMICs
under the REMIC Provisions and shall assist each other as necessary to create or
maintain such status.  Neither the Trustee nor

                                       48
<PAGE>
 
the Holder of any Class R Certificate shall take any action, cause the Trust
Fund to take any action or fail to take (or fail to cause the Trust Fund to
take) any action that, under the REMIC Provisions, if taken or not taken, as the
case may be, could (i) endanger the status of any REMIC as a REMIC or (ii)
result in the imposition of a tax upon either REMIC (other than on net income
from foreclosure of REO Property), the tax on prohibited transactions as defined
in Code Section 860F(a)(2) and the tax on prohibited contributions set forth in
Section 860G(d) of the Code) (either such event, an "Adverse REMIC Event")
unless the Trustee has received an Opinion of Counsel (at the expense of the
person seeking to take such action) to the effect that the contemplated action
will not endanger such status or result in the imposition of such a tax.

               (i)  The Trustee shall provide (i) to any transferor of a Class R
Certificate and to the Internal Revenue Service such information as is necessary
for the application of any tax relating to the transfer of such Class R
Certificate to any Person who is Disqualified Organization or is not a U.S.
Person, (ii) to the Certificateholders such information or reports as are
required by the Code or the REMIC Provisions, including reports relating to
interest, original issue discount and market discount or premium and (iii) to
the Internal Revenue Service the name, title, address and telephone number of
the individual who will serve as the representative of each REMIC.

               (j)  Except as provided in Section 3.14, neither the Trustee, the
Master Servicer nor the Special Servicer shall sell, dispose of, modify or
substitute for any of the Mortgage Loans (except in connection with (i) the
default, imminent default or foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by a deed
in lieu of foreclosure, (ii) the bankruptcy of the Trust Fund, (iii) the
termination of the REMICs pursuant to Article X of this Agreement or (iv) a
purchase or substitution of Mortgage Loans pursuant to Article II or III of this
Agreement) or acquire any assets for either REMIC, or sell or dispose of any
investments in the Collection Account or the Distribution Account for gain, or
accept any contributions to the REMICs after the Delivery Date unless it has
received an Opinion of Counsel at the expense of the Trust Fund (unless such
substitution is performed by the Seller as a result of a defect or breach of
representations or warranties under the Mortgage Loan Purchase Agreement in
which case such Opinion shall be at the expense of the Seller) that such sale,
disposition, substitution, modification or acquisition would not result in an
Adverse REMIC Event.  The Trustee, the Fiscal Agent, the Master Servicer and the
Special Servicer shall be entitled to rely conclusively on such Opinion of
Counsel.

               (k)  In order to enable the Trustee to perform its duties as set
forth herein, the Depositor shall provide, or cause to be provided to the
Trustee, within ten days after the Delivery Date, all information or data on a
computer diskette that the Trustee reasonably requests or the Depositor
determines to be relevant for tax purposes to the valuations and offering prices
of the Certificates, including the price, yield, prepayment assumption and
projected cash flows of the Certificates and the Mortgage Loans and the Trustee
shall be entitled to rely upon any and all such information and data in the
performance of its duties set forth herein. Thereafter, the Master Servicer or
the Special Servicer, as the case may be, shall provide promptly upon request
therefor any such additional information or data with respect to the applicable
Mortgage Loans or otherwise in their respective possession or

                                       49
<PAGE>
 
reasonably available to them that the Trustee may from time to time reasonably
request in order to enable the Trustee to perform its duties as set forth herein
and the Trustee shall be entitled to rely upon any and all such information and
data in the performance of its duties set forth herein.  The Depositor shall
indemnify the Trustee and hold it harmless for any loss, liability, damage,
claim or expense of the Trustee arising from any failure of the Depositor to
provide, or to cause to be provided, accurate information or data to the Trustee
on a timely basis.  The indemnification provisions hereunder shall survive the
termination of this Agreement and shall extend to any co-trustee appointed
pursuant to this Agreement.


                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

               SECTION 3.01.  SERVICING STANDARD; SERVICING DUTIES.
                              ------------------------------------ 

               (a)  Except as provided in Section 3.01(b) and subject to the
express provisions of this Agreement, for and on behalf of the Trust Fund and
for the benefit of the Certificateholders as a whole (as determined by the
Master Servicer or the Special Servicer (with respect to Specially Serviced
Mortgage Loans being serviced by the Special Servicer) in their respective
reasonable judgment without taking into account any differing payment priorities
or any interest of the Master Servicer or the Special Servicer in any Class of
Certificates or other rights under this Agreement), the Master Servicer and the
Special Servicer (severally and not jointly) shall service and administer the
Mortgage Loans and REO Properties in accordance with the Servicing Standard,
subject to specific provisions and requirements of this Agreement.

               The "Servicing Standard" shall mean the higher of the following
standards of care:

                    (i)  the same manner in which and with the same care, skill,
     prudence and diligence with which the Master Servicer or the Special
     Servicer, as the case may be, services and administers similar mortgage
     loans for other third-party portfolios, giving due consideration to
     customary and usual standards of practice of prudent institutional
     commercial mortgage lenders servicing their own loans and to the
     maximization of the net present value of the mortgage loans; and

                   (ii)  the care, skill, prudence and diligence the Master
     Servicer or the Special Servicer, as the case may be, uses for loans which
     it owns and which are substantially the same as the Mortgage Loans.

               The Master Servicer and the Special Servicer shall adhere to the
foregoing servicing standards notwithstanding any potential conflicts of
interest which may arise during the course of the transaction contemplated
hereby, including, without limitation, (i) any relationship that the Master
Servicer or the Special Servicer, as the case may be, or any of their respective
Affiliates may have with a Mortgagor, the Depositor or other parties to the

                                       50
<PAGE>
 
transaction contemplated hereby; (ii) the ownership of any Certificates by the
Master Servicer or the Special Servicer, as the case may be, or any of their
respective Affiliates; (iii) the Master Servicer's or the Special Servicer's
right to receive compensation or other fees for its services rendered pursuant
to this Agreement; (iv) the Master Servicer's or the Special Servicer's (or any
other party's) obligations to make advances or otherwise incur servicing
expenses with respect to the Mortgage Loans; (v) the ownership, servicing or
management for others of any other mortgage loans or mortgaged property; and
(vi) any obligation, if any such obligation is expressly set forth in this
Agreement, of the Master Servicer or the Special Servicer to pay any indemnity
with respect to any Mortgage Loan.

               In connection with such servicing and administration, the Master
Servicer or the Special Servicer, as the case may be, shall seek to maximize the
timely recovery of principal and interest on the Mortgage Notes in the best
economic interests of the Certificateholders as a whole; 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 collectibility of payments
on the Mortgage Loans or shall be construed as impairing or adversely affecting
any rights or benefits specifically provided by this Agreement to the Master
Servicer and the Special Servicer, including with respect to Servicing Fees and
Special Servicer Compensation or right to be reimbursed for Advances.  To the
extent consistent with the foregoing and subject to any express limitations and
provisions set forth in this Agreement, the Master Servicer and the Special
Servicer shall have full power and authority to do or cause to be done any and
all things that they may deem necessary or desirable in connection with such
servicing and administration, including but not limited to, the power and
authority, subject to the terms hereof, (a) to execute and deliver, on behalf of
the Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents (including, without limitation, estoppel certificates,
financing statements, continuation statements and other documents and
instruments necessary to preserve and maintain the lien on the related Mortgaged
Property and related collateral), (b) to consent to transfers of any applicable
Mortgaged Property and assumptions of the applicable Mortgage Notes and related
Mortgages, (c) to collect any applicable Insurance Proceeds and applicable
Liquidation Proceeds, (d) to consent to any subordinate financings to be secured
by any applicable Mortgaged Property to the extent that such consent is required
pursuant to the terms of the related Mortgage, (e) to consent to the application
of any proceeds of insurance policies or condemnation awards to the restoration
of the applicable Mortgaged Property or otherwise, (f) to bring an action in a
court of law to enforce rights of the Trustee and the Certificateholders with
respect to the applicable Mortgaged Properties, (g) to execute and deliver, on
behalf of the Certificateholders and the Trustee, documents relating to the
management, operation, maintenance, repair, leasing, marketing and sale of the
applicable Mortgaged Properties and any REO Property, (h) to effectuate
foreclosure or other conversion of the ownership of the applicable Mortgaged
Property securing any Mortgage Loan, (i) to obtain, release, waive or modify any
terms and provisions of the Mortgage Loans and related documents, (j) to
exercise all rights, powers and privileges granted or provided to the holder of
the Mortgage Notes under the terms of the Mortgage, including all rights of
consent or approval thereunder, and (k) to take such actions as the Master
Servicer and the Special Servicer deems necessary or desirable in connection
with any bankruptcy or insolvency proceedings in any way affecting the rights of
the Trustee and the Certificateholders in any of the Mortgage Loans.  Nothing
contained in this Agreement shall

                                       51
<PAGE>
 
limit the ability of the Master Servicer or the Special Servicer to lend money
to (to the extent not secured, in whole or in part, by any Mortgaged Property),
accept deposits from and otherwise generally engage in any kind of business or
dealings with any Mortgagor as though the Master Servicer or the Special
Servicer were not a party to this Agreement or to the transactions contemplated
hereby.

               (b)  The Special Servicer shall be obligated to service,
administer and make Advances on only the Mortgage Loans which have become and
continue to be Specially Serviced Mortgage Loans. The Master Servicer shall be
required to make all calculations and prepare all reports required hereunder
with respect to such Specially Serviced Mortgage Loans (other than calculations
and reports expressly required to be made by the Special Servicer hereunder) as
if no Servicing Transfer Event had occurred and shall continue to collect all
Monthly Payments, make certain Property Protection Advances as set forth herein
and to render such incidental services with respect to such Specially Serviced
Mortgage Loans, all as are specifically provided for herein, but shall have no
other servicing or other duties with respect to such Specially Serviced Mortgage
Loans (including any duty to make Monthly Advances with respect thereto). The
Master Servicer shall give notice within one Business Day to the Special
Servicer of any collections it receives from any Specially Serviced Mortgaged
Loans. The Special Servicer shall instruct within one Business Day after
receiving such notice the Master Servicer on how to apply such funds. The Master
Servicer within one Business Day after receiving such instructions shall apply
such funds in accordance with the Special Servicer's instructions. Each Mortgage
Loan that becomes a Specially Serviced Mortgage Loan shall continue as such
until satisfaction of the conditions specified in Section 3.27. The Master
Servicer shall not be required to initiate extraordinary collection procedures
or legal proceedings with respect to any Mortgage Loan or to undertake any pre-
foreclosure procedures. Subject only to the Servicing Standard and the terms of
this Agreement and of the respective Mortgage Loans, the Master Servicer and the
Special Servicer shall each have full power and authority 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)  Without limiting the generality of the foregoing, each of
the Master Servicer and the Special Servicer, as the case may be, in its own
name or in the name of the Trustee, is hereby authorized and empowered by the
Trustee, when the Master Servicer or the Special Servicer, as the case may be,
believes it appropriate in its best judgment, to execute and deliver, on behalf
of the Trustee, the Certificateholders or any of them, any and all instruments
of satisfaction, cancellation or assignment, or of partial or full release or
discharge and all other comparable instruments, with respect to the Mortgage
Loans, and with respect to the Mortgaged Properties held for the benefit of the
Certificateholders. The Master Servicer or the Special Servicer, as the case may
be, shall promptly notify the Trustee of any such execution and delivery. Upon
receipt of written request of the Master Servicer or the Special Servicer
accompanied by an Officer's Certificate that such document or documents are
necessary or appropriate for the servicing of the Mortgage Loans, the Trustee
shall furnish the Master Servicer and the Special Servicer with any powers of
attorney and other documents necessary or appropriate to enable the Master
Servicer or the Special Servicer to service and administer the Mortgage Loans
including, without limitation, powers of attorney and documents relating to the
management, operation, maintenance,

                                       52
<PAGE>
 
repair, leasing, marketing and sale of the Mortgaged Properties and the sale of
any Specially Serviced Mortgage Loan or REO Property.

               (d)  The Master Servicer shall segregate and hold all funds
collected and received pursuant to any Mortgage Loan constituting Escrow
Payments separate and apart from any of its own funds and general assets and
shall establish and maintain one or more segregated custodial accounts (each, a
"Reserve Account") into which all Escrow Payments shall be deposited within one
(1) Business Day after receipt. The Master Servicer shall also deposit into each
Reserve Account any amounts representing losses on Eligible Investments pursuant
to the immediately succeeding paragraph and any Insurance Proceeds or
Liquidation Proceeds which are required to be applied to the restoration or
repair of any Mortgaged Property pursuant to the related Mortgage Loan. Each
Reserve Account shall be maintained in accordance with the requirements of the
related Mortgage Loan and in accordance with the Servicing Standard. Withdrawals
from a Reserve Account may be made by the Master Servicer only:

               (i)  to effect timely payments of items constituting Escrow
                    Payments for the related Mortgage Loan;

              (ii)  to transfer funds to the Collection Account to reimburse the
                    Master Servicer or the Special Servicer, as the case may be,
                    for any Advance relating to Escrow Payments, but only from
                    amounts received with respect to the related Mortgage Loan
                    which represent late collections of Escrow Payments
                    thereunder;

             (iii)  for application to the restoration or repair of the related
                    Mortgaged Property in accordance with the related Mortgage
                    Loan and the Servicing Standard;

              (iv)  to clear and terminate such Reserve Account upon the
                    termination of this Agreement or pay-off of the related
                    Mortgage Loan;

               (v)  to pay from time to time to the related Mortgagor any
                    interest or investment income earned on funds deposited in
                    the Reserve Account if such income is required to be paid to
                    the related Mortgagor under applicable law or by the terms
                    of the Mortgage Loan, or otherwise to the Master Servicer;
                    and

              (vi)  to remove any funds deposited in a Reserve Account that were
                    not required to be deposited therein or to refund amounts to
                    the Mortgagors determined to be overages.

               Subject to the immediately succeeding sentence, (i) the Master
Servicer may direct any depository institution or trust company in which the
Reserve Accounts are maintained to invest the funds held therein in one or more
Eligible Investments; provided, however, that such funds shall be either (x)
                      --------  -------                                     
immediately available or (y) available in accordance with a schedule which will
permit the Master Servicer to meet the payment

                                       53
<PAGE>
 
obligations for which the Reserve Account was established; (ii) the Master
Servicer shall be entitled to all income and gain realized from any such
investment of funds as additional servicing compensation; and (iii) the Master
Servicer shall deposit from its own funds in the applicable Reserve Account the
amount of any loss incurred in respect of any such investment of funds
immediately upon the realization of such loss.  The Master Servicer shall not
direct the investment of funds held in any Reserve Account and retain the income
and gain realized therefrom if the terms of the related Mortgage Loan or
applicable law permit the Mortgagor to be entitled to the income and gain
realized from the investment of funds deposited therein.  In such event, (1) the
Master Servicer shall direct the depository institution or trust company in
which such Reserve Accounts are maintained to invest the funds held therein in
accordance with the Mortgagor's written investment instructions, if the terms of
the related Mortgage Loan or applicable law require the Master Servicer to
invest such funds in accordance with the Mortgagor's directions; and (2) in the
absence of appropriate written instructions from the Mortgagor, the Master
Servicer shall have no obligation to, but may be entitled to, direct the
investment of such funds; provided, however, that in either event (i) such funds
                          --------  -------                                     
shall be either (y) immediately available or (z) available in accordance with a
schedule which will permit the Master Servicer to meet the payment obligations
for which the Reserve Account was established, and (ii) the Master Servicer
shall have no liability for any loss in investments of such funds that are
invested pursuant to written instructions from the Mortgagor.

               (e)   The relationship of each of the Master Servicer and the
Special Servicer to the Trustee under this Agreement is intended by the parties
to be that of an independent contractor and not of a joint venturer, partner or
agent.

               (f)   With respect to each Mortgage Loan, if required by the
terms of the related Mortgage, any Lock-Box Agreement or similar agreement, the
Master Servicer or the Special Servicer, as the case may be, shall establish and
maintain one or more accounts (either "Lock-Box Accounts") to be held outside
the Trust Fund and maintained by the Master Servicer or the Special Servicer in
accordance with the terms of the related Mortgage. No Lock-Box Account needs to
be an Eligible Account. The Master Servicer or the Special Servicer, as the case
may be, shall apply the funds deposited in such accounts in accordance with
terms of the related Mortgage and any Lock-Box Agreement and in accordance with
the Servicing Standard.

               SECTION 3.02.  SUB-SERVICING.
                              ------------- 

               As part of its servicing activities hereunder, each of the Master
Servicer and the Special Servicer, as the case may be, may appoint one or more
sub-servicers (each, a "Sub-Servicer") to perform all or any portion of their
respective duties hereunder and severally and not jointly, for the benefit of
the Trustee and the Certificateholders, shall supervise, administer, monitor,
enforce and oversee the servicing of the applicable Mortgage Loans by any Sub-
Servicer appointed by it.  The Master Servicer intends to appoint initially
Wells Fargo Realty Finance Corporation, a wholly-owned subsidiary of Wells Fargo
Bank, National Association, to sub-service the Mortgage Loans.  The terms of any
arrangement or agreement between the Master Servicer and a Sub-Servicer, or the
Special Servicer and a Sub-Servicer, as the case may be, shall provide that such
agreement or arrangement may be

                                       54
<PAGE>
 
terminated by the Trustee in the event such Master Servicer or Special Servicer
is terminated in accordance with this Agreement.  The Master Servicer and the
Special Servicer, as the case may be, severally and not jointly, shall pay the
costs of enforcement against any of its Sub-Servicers at its own expense, but
shall be reimbursed therefor only (i) from a general recovery resulting from
such enforcement only to the extent that such recovery exceeds all amounts due
in respect of the related Mortgage Loans or (ii) from a specific recovery of
costs, expenses or attorneys fees against the party against whom such
enforcement is directed.  A Sub-Servicer under a Sub-Servicing Agreement shall
not agree to any modification, waiver, amendment or consent in respect of a
Specially Serviced Mortgage Loan pursuant to Section 3.26 hereof without the
consent of the Special Servicer.  Notwithstanding the provisions of any Sub-
Servicing Agreement, any of the provisions of this Agreement relating to
agreements or arrangements between the Master Servicer, the Special Servicer or
a Sub-Servicer or reference to actions taken through a Sub-Servicer or
otherwise, the Master Servicer or the Special Servicer, as the case may be,
severally and not jointly, shall remain obligated and liable to the Trustee and
the Certificateholders for the servicing and administering of the applicable
Mortgage Loans and any REO Property included in the Trust Fund in accordance
with (and subject to the limitations contained within) the provisions of this
Agreement without diminution of such obligation or liability by virtue of any
Sub-Servicing Agreement or by virtue of indemnification from a Sub-Servicer and
to the same extent and under the same terms and conditions as if the Master
Servicer or the Special Servicer, as the case may be, alone were servicing and
administering the Mortgage Loans.

          SECTION 3.03.  RESERVED.
                         -------- 

          SECTION 3.04.  CERTAIN CONDITIONS RELATING TO REO PROPERTY.  
                         -------------------------------------------   
Subject to the following sentence, but otherwise notwithstanding any other
provision of this Agreement, none of the Master Servicer and the Special
Servicer (and any Sub-Servicer) shall (i) rent, lease or otherwise earn net
income with respect to REO Property (other than with respect to its
disposition), (ii) authorize or permit any construction with respect to any REO
Property, or (iii) Directly Operate (or allow any other person other than an
Independent Contractor to Directly Operate) the REO Property, in each case
without an Opinion of Counsel at the expense of the Trust Fund and reimbursable
to the Master Servicer or the Special Servicer, as the case may be, pursuant to
Section 3.12(f), to the effect that such action will not cause the REO Property
to be other than "foreclosure property" within the meaning of Section 860G(a)(8)
of the Code or to generate "net income from foreclosure property" within the
meaning of Section 860G(c) of the Code upon prior written consent of the Master
Servicer, such consent not to be unreasonably withheld. However, subject to the
other provisions of this Agreement, (i) an Independent Contractor (which may
include the Master Servicer, the Special Servicer or any Sub-Servicer) may enter
into and renew a fixed rent lease arrangement with respect to an REO Property
with an unrelated party provided that (a) in the judgment of the Special
Servicer such lease does not hamper the disposition of the property, (b) any
sublease of such property is also a fixed rent arrangement, and (c) rent
attributable to any related personal property does not constitute more than 15
percent of the total rent received or accrued under the lease for the year, and
(ii) construction or tenant improvements with respect to REO Property in the
nature of repair or maintenance, other improvement to offset normal wear and
tear or obsolescence, or restoration required because of damage from fire,
storm, vandalism or other casualty shall be permissible.

          SECTION 3.05.  OPERATING ADVISOR.
                         ----------------- 
         
          (a)    At any time the Certificate Principal Balance of the most
subordinate Class (other than the Class R-I and Class R-II Certificates) is
greater than 25% of the initial Certificate Principal Balance of such Class, the
Holders of a majority of the Certificates of such Class by Certificate Principal
Balance will have the right to appoint a Person, which may be a Holder (each, an
"Operating Advisor"), that will have the right to approve the actions of the
Special Servicer as set forth in Section 3.30. Promptly upon its appointment,
the Operating Advisor will notify the Master Servicer, the Special Servicer,
each Rating Agency, the Depositor and the Trustee of its appointment and its
acceptance of the terms thereof as set forth herein. Initially, the requisite
Holders of the Class G Certificates shall have the right to appoint an Operating
Advisor. Upon the occurrence of a Trigger Event with respect to Class G
Certificates, the requisite Holders of Class F Certificates, respectively, shall
have the right to appoint an Operating Advisor. Upon the occurrence of a Trigger
Event with respect to the Class F Certificates, the requisite holders of Class E
Certificates shall have the right to appoint an Operating Advisor. If a Trigger
Event occurs thereafter, a majority of the Holders of the next most subordinate
Class of Certificates will have the right to appoint the Operating Advisor and
the Operating Advisor appointed by any Class as to which the Trigger Event
occurred shall, after the appointment of the new Operating Advisor, no longer be
an Operating Advisor. A "Trigger Event" occurs with respect to a Class of
Certificates when the Certificate Principal Balance of such Class is reduced to
25% or less of its initial Certificate Principal Balance.

          (b)  An Operating Advisor may be removed at any time by a written
notice of not less than a majority (by Certificate Principal Balance) of Holders
of the Class entitled at such time to appoint such Operating Advisor.

          SECTION 3.06.  RIGHTS OF THE DEPOSITOR, THE TRUSTEE AND THE
                         --------------------------------------------
                         CERTIFICATEHOLDERS IN RESPECT OF THE MASTER
                         -------------------------------------------
                         SERVICER AND THE SPECIAL SERVICER.
                         --------------------------------- 

          (a)   The Master Servicer and the Special Servicer shall afford the
Rating Agencies, the Depositor, the Trustee, the Fiscal Agent, the Special
Servicer, the Master Servicer or any Certificateholder, and, with respect to any
Specially Serviced Mortgage Loan, the Operating Advisor, upon reasonable notice
and during normal business hours, reasonable access to all relevant, non-
privileged and non-confidential, records and documentation regarding the
applicable Mortgage Loans, REO Property and all accounts, insurance policies and
other relevant matters relating to this Agreement, and access to Servicing
Officers of the Master Servicer and the Special Servicer responsible for their
obligations hereunder. Copies of information or access will be provided to
Certificateholders and each Beneficial Holder providing satisfactory evidence of
ownership of Certificates or beneficial ownership of a Certificate, as the case
may be. Copies (or computer diskettes or other digital or electronic copies of
such information if reasonably available in lieu of paper copies) of any and all
of the foregoing items shall be made available by the Master Servicer and the
Special Servicer upon request; provided, however, that the Master Servicer and
                               --------  -------                              
the Special Servicer shall be permitted to require payment by the requesting
party (other than the Trustee or either Rating Agency) of a sum sufficient to
cover the reasonable expenses

                                       56
<PAGE>
 
actually incurred by the Master Servicer or the Special Servicer of providing
access or copies (including electronic or digital copies) of any such
information requested in accordance with the preceding sentence.

          (b)   Upon reasonable advance written notice, if required by federal
regulation, the Master Servicer and the Special Servicer will provide to each
Certificateholder that is a savings association, bank or insurance company
certain reports and access to information and documentation in the possession of
or reasonably available to the Master Servicer or the Special Servicer, as the
case may be, regarding the Mortgage Loans sufficient to permit such
Certificateholder to comply with applicable regulations of the Office of Thrift
Supervision or other regulatory authorities with respect to investment in the
Certificates; provided, however, that the Master Servicer and the Special
              --------  -------                                          
Servicer shall be entitled to be reimbursed by each such Certificateholder for
the Master Servicer's or the Special Servicer's actual expenses incurred in
providing such reports and access.

          (c)   Neither the Depositor nor the Trustee shall have any 
responsibility or liability for any action or failure to act by the Master
Servicer and the Special Servicer and neither is obligated to supervise the
performance of the Master Servicer and the Special Servicer hereunder or
otherwise. Nothing herein shall be deemed to require the Trustee, the Depositor,
the Master Servicer or the Special Servicer, as applicable, to confirm,
represent or warrant the accuracy of (or to be liable or responsible for) any
other Person's information or report, included in any communication from the
Depositor, the Master Servicer, the Special Servicer or the Trustee, as the case
may be. Notwithstanding the above, the Master Servicer and the Special Servicer
shall not have any liability to the Depositor, the Trustee, any
Certificateholder, any Rating Agency or any other Person to whom it delivers
information pursuant to this Section or any other provision of this Agreement
for federal, state or other applicable securities law violations relating to the
disclosure of such information by the Master Servicer or the Special Servicer.
In the event any Person brings any claims relating to or arising from the
foregoing against the Master Servicer or the Special Servicer (or any employee,
attorney, officer, director or agent thereof), the Trust Fund (from amounts held
in any account or otherwise) shall hold harmless and indemnify the Master
Servicer and the Special Servicer from such claims in accordance with Section
7.03 hereof.

          (d)   The Special Servicer and the Master Servicer shall produce
the reports required of it under this Agreement; provided, however, that the
                                                 --------  -------
Special Servicer and the Master Servicer shall not be required to produce any
ad hoc non-standard written reports with respect to such Mortgage Loans except
- -- ---
if any Person other than the Depositor, Rating Agencies or the Trustee
requesting such report pays a reasonable fee to be determined by the Special
Servicer or the Master Servicer, as applicable. Notwithstanding anything to the
contrary herein, as a condition to the Special Servicer or the Master Servicer
making any report or information available upon request to any Person other than
the parties hereto, the Special Servicer and the Master Servicer may require
that the recipient of such information acknowledge that the Special Servicer or
the Master Servicer, as the case may be, may contemporaneously provide such
information to the Depositor, the Trustee and/or the Certificateholders. Any
transmittal of information by the Special Servicer or the Master Servicer to any
Person other than the Trustee, the Master Servicer, the Special Servicer, the

                                       57
<PAGE>
 
Rating Agencies or the Depositor may be accompanied by a letter from the Master
Servicer or the Special Servicer, as the case may be, containing the following
provision:

          "By receiving the information set forth herein, you hereby acknowledge
          and agree that (and you will obtain the acknowledgement and agreement
          of any person who receives this information from you or at your
          direction) the United States securities laws restrict any person who
          possesses material, non-public information regarding the Trust Fund
          which issued CS First Boston Mortgage Securities Corp., Commercial
          Mortgage Pass-Through Certificates, Series 1995 - WF1 from purchasing
          or selling such Certificates and from communicating such information
          to any other person under circumstances in which it is reasonably
          foreseeable that such person is likely to purchase or sell such
          Certificates."

Any person may call the Special Servicer at (214) 290-2674 in order to inquire
as to how to obtain such information.  The parties hereto further agree that the
Special Servicer may, but shall not be obligated to (unless otherwise provided
in this Agreement) disseminate all reports and information relative to the
Specially Serviced Mortgage Loans electronically or otherwise to any Person.

          SECTION 3.07.  MASTER SERVICER TO ACT AS SPECIAL SERVICER; 
                         -------------------------------------------
                         TRUSTEE TO ACT AS MASTER SERVICER OR SPECIAL
                         --------------------------------------------
                         SERVICER. 
                         --------

          The Special Servicer may resign, or be removed at any time with
or without cause, by the written vote of the Holders of more than 50% of the
Certificate Principal Balance of the Class of Certificates which has the right
to select the Operating Adviser under Section 3.05; provided, that no such
                                                    --------              
resignation or removal will be effective until a qualified successor Special
Servicer reasonably acceptable to the Operating Advisor (to the extent that the
Operating Advisor has been appointed) has been appointed and accepted such
appointment.  Prior to the effectiveness of the appointment of any successor
Special Servicer, the Trustee shall have received written confirmation from each
Rating Agency then rating the Certificates that the appointment of such
successor Special Servicer would not, in and of itself, result in the
qualification, reduction or withdrawal of the ratings at the time assigned to
any Class of Certificates.  If the Special Servicer shall for any reason no
longer be the Special Servicer, and a replacement Special Servicer has not been
appointed, accepted and approved in the manner set forth above, upon receipt of
written notice of the same from the Trustee, the Master Servicer shall assume
all the rights and future obligations of the Special Servicer hereunder except
where the Special Servicer which is removed or resigned is the same entity as
the Master Servicer.  Upon the assumption by the Master Servicer of the duties
of the Special Servicer, references in this Agreement to the "Special Servicer"
shall refer to the Master Servicer in its capacity as the Special Servicer.  If
the Master Servicer shall for any reason no longer be the Master Servicer or the
Special Servicer hereunder (including by reason of an Event of Default),
consistent with the provisions of Section 8.02, the Trustee, shall thereupon
assume all of the rights and obligations of the Master Servicer or the Special
Servicer, as the case may be, hereunder arising thereafter except that the
Trustee shall not be (i) liable for losses of the Master Servicer and the
Special Servicer pursuant to

                                       58
<PAGE>
 
Section 3.08 hereof or (ii) obligated to make Monthly Advances if prohibited by
applicable law.

          In the event that the Master Servicer or the Special Servicer, as
applicable, shall resign or be removed, each of the Master Servicer or the
Special Servicer, as the case may be, shall, upon request of the Trustee, at the
expense of the Master Servicer or the Special Servicer respectively, (i) deliver
to the assuming party all documents and records relating to the Mortgage Loans
then being serviced by such assuming party, (ii) deliver an accounting of
amounts collected and held by the Master Servicer or the Special Servicer, as
the case may be, and (iii) use its best efforts to effect the orderly and
efficient transfer of servicing of the Mortgage Loans to the assuming party.

          SECTION 3.08.  COLLECTION OF MORTGAGE LOAN PAYMENTS AND
                         ----------------------------------------
                         COLLECTION ACCOUNT.
                         ------------------ 

          The Master Servicer and the Special Servicer, severally and not
jointly, shall make reasonable efforts to collect all payments called for under
the terms and provisions of the applicable Mortgage Loans and shall, to the
extent such procedures shall be consistent with this Agreement, follow such
collection procedures as are consistent with the Servicing Standard.

          The Master Servicer shall establish and maintain, in the name of the
Trustee on behalf of the Certificateholders, the Collection Account. Except with
respect to collections on Specially Serviced Mortgage Loans (which shall be
applied in accordance with Section 3.01 (b) hereof), the Master Servicer shall
deposit into the Collection Account on a daily basis within one (1) Business Day
after receipt thereof (A) all monies received from the Special Servicer pursuant
to Section 3.09 except as otherwise specifically provided herein and (B) the
following payments and collections received or made by it subsequent to the Cut-
off Date (other than in respect of principal of and interest on the Mortgage
Loans due on or before the Cut-off Date):

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

                   (ii)  all payments on account of interest on the Mortgage
     Loans;

                  (iii)  all Insurance Proceeds and Net Liquidation Proceeds;

                   (iv)  all Monthly Advances made by the Master Servicer, the
     Special Servicer, the Trustee or the Fiscal Agent pursuant to Sections 5.01
     hereof unless paid directly to the Distribution Account;

                    (v)  any amount of any losses required to be deposited by
     the Master Servicer pursuant to the last paragraph of this Section 3.08 in
     connection with any losses on Eligible Investments;

     Servicer or Special Servicer pursuant to Section 3.13 hereof;

                  (vii)  all proceeds of any Mortgage Loans or property acquired
     in respect of the Mortgage Loans purchased pursuant to Sections 2.01, 2.02,
     2.03, 3.11 or 10.01 hereof and all amounts required to be deposited in
     connection with the substitution of Replacement Mortgage Loans pursuant to
     Sections 2.01, 2.02 or 2.03 hereof; and

                 (viii)  any other amounts required to be deposited in the
     Collection Account pursuant to this Agreement including, without
     limitation, the amounts required to be deposited therein pursuant to
     Section 3.15 hereof.

          The Master Servicer shall be entitled to receive as additional
compensation the following amounts collected on the Mortgage Loans which are not
Specially Serviced Mortgage Loans: late payment charges, assumption fees,
extension fees, servicing fees, modification fees, forbearance fees, and other
usual and customary fees collected from the Mortgagor, including fees common in
bankruptcy and workout situations, collected by virtue of default or other non-
compliance by the Mortgagor with the terms of the Mortgage or any other
instrument or document executed in connection therewith or otherwise, if
collected, need not be remitted by the Master Servicer and may be retained as
additional servicing compensation by the Master Servicer. The Special Servicer
shall retain as additional compensation similar amounts received by it with
respect to the Specially Serviced Mortgage Loans. In the event that the Master
Servicer or the Special Servicer, as the case may be, shall deposit any amount
not required to be deposited and not otherwise subject to withdrawal pursuant to
Section 3.12 hereof, the Master Servicer may at any time withdraw such amount
from the Collection Account and retain such portion for itself or remit such
portion to the Special Servicer as applicable, any provision herein to the
contrary notwithstanding. All funds deposited in the Collection Account shall be
held in the name of the Trustee in trust for the Certificateholders until
disbursed in accordance with this Agreement or withdrawn in accordance with
Section 3.12. In no event shall the Trustee incur liability for withdrawals from
the Collection Account at the direction of the Master Servicer.

          The Master Servicer may invest the funds in the Collection Account in
Eligible Investments, which shall mature not later than the Business Day
preceding the Servicer Remittance Date following the date of such investment.
All such Eligible Investments shall be made in the name of the Trustee for the
benefit of the Certificateholders or its nominee. All income and gain net of any
losses realized from any such investment shall be for the benefit of the Master
Servicer as additional servicing compensation and shall be subject to withdrawal
at its direction from time to time. The amount of any losses net of any gains
incurred in respect of any such investments shall be remitted by the Master
Servicer to the Trustee for deposit in the Distribution Account or deposited in
the Collection Account out of the Master Servicer's own funds on or prior to the
next Servicer Remittance Date.

          SECTION 3.09.  REMITTANCES BY SPECIAL SERVICER.
                         ------------------------------- 

          Except with respect to any REO Account Mortgage Loan, upon the receipt
by the Special Servicer of any of the amounts described in clauses (i), (ii),
(iii), (vi), (vii) and (viii) of Section 3.08, the Special Servicer shall remit
within one Business Day such amounts to the Master Servicer for deposit into the
Collection Account. With respect to any such amounts required to be remitted to
the Master Servicer, the Special Servicer shall endorse any checks received to
the order of the Master Servicer and shall deliver within one Business Day any
such checks or funds to the Master Servicer by overnight courier or comply with
other reasonable instructions of the Master Servicer with respect thereto.

          SECTION 3.10.  REO ACCOUNT; MANAGEMENT OF REO PROPERTIES.
                         ----------------------------------------- 

          In the event that title to any Mortgaged Property is acquired for the
benefit of Certificateholders in foreclosure, by deed in lieu of foreclosure or
otherwise, the deed or certificate of sale shall be taken in the name of the
Trustee (in such capacity), or its nominee, on behalf of the Trust Fund. The
Special Servicer responsible for such REO Property shall, on behalf of the Trust
Fund, dispose of each REO Property in accordance with Section 3.11. Unless an
appraisal shall have been obtained within the preceding twelve month period in
connection with the foreclosure and acquisition of such REO Property, an
Appraisal Reduction or a Realized Loss, promptly following any acquisition by
the Trust Fund of an REO Property, the Special Servicer shall obtain a narrative
MAI appraisal thereof conducted by an independent and MAI certified appraiser at
the expense of the Trust Fund, in order to determine the estimated fair market
value of the related Mortgaged Property or REO Property and shall notify the
other parties hereto of the results of such appraisal.

          The Special Servicer shall segregate and hold all funds collected and
received in connection with the operation of each applicable REO Property
separate and apart from its own funds and general assets and shall establish and
maintain with respect to the REO Properties a separate account or accounts held
in trust for the benefit of the Certificateholders in the name of the Trustee
(an "REO Account"), which shall be an Eligible Account, and will account
separately for funds received or expended with respect to each such REO
Property. All funds in each REO Account may only be invested in Eligible
Investments. The Special Servicer shall notify the Trustee, the Fiscal Agent and
the Master Servicer in writing of the location and account number of each REO
Account and shall notify the Trustee prior to any subsequent change thereof. All
income and gain net of any losses realized from any such investment shall be for
the benefit of the Special Servicer and shall be subject to withdrawal at its
direction from time to time. The amount of any losses net of any gains not paid
to the Special Servicer that are incurred in respect of any such investments
shall be deposited in the REO Account out of the Special Servicer's own funds
not later than the Special Servicer Remittance Date next succeeding the date on
which such losses are realized.

          The Special Servicer shall have full power and authority, subject only
to the specific requirements and prohibitions of this Agreement, to do any and
all things in connection with any applicable REO Property as are consistent with
the Servicing Standard. In connection therewith, the Special Servicer shall
deposit or cause to be deposited on a daily basis in the applicable REO Account
all revenues received by it within one Business Day

                                       61
<PAGE>
 
after receipt thereof with respect to each applicable REO Property and the
related REO Account Mortgage Loan, and shall withdraw therefrom funds necessary
for the proper operation, management and maintenance of such REO Property,
including:

                    (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)  all customary and reasonable costs and expenses
          necessary to maintain, repair, appraise, evaluate, manage or operate
          such REO Property (including, without limitation, the fees and
          expenses of a third party property manager);

                   (iv)  all costs and expenses of capital improvements and
          tenant improvements; and

                    (v) all other costs and expenses, including attorneys' fees,
          which the Special Servicer may suffer or incur in connection with its
          performance of this Agreement with respect to such REO Property.

          To the extent that amounts on deposit in the applicable REO Account
are insufficient for the purposes set forth in clauses (i) through (iv) above,
the Special Servicer shall make all Property Protection Advances; provided,
                                                                  -------- 
however, that the Special Servicer shall be entitled to reimbursement (including
- -------                                                                         
interest accrued thereon at the Advance Rate) therefor pursuant to Section 3.12.
The Special Servicer shall promptly, and in no event later than three Business
Days after the making of a Property Protection Advance, give written notice to
the Master Servicer of the making by the Special Servicer of such Advance.

          On or before the Special Servicer Remittance Date, the Special
Servicer shall withdraw from each REO Account and remit to the Master Servicer
for deposit into the Collection Account the proceeds and collections received or
collected during the period since the applicable second preceding Special
Servicer Determination Date to the Special Servicer Determination Date
immediately preceding the Special Servicer Remittance Date on or with respect to
the related REO Account Mortgage Loans, net of related expenses (as set forth in
the second preceding paragraph above), together with any Monthly Advances on the
Specially Serviced Mortgage Loans; provided, however, the Special Servicer may
                                   --------  -------                          
retain in the applicable REO Account such portion of such proceeds and
collections as may be necessary to maintain in the REO Account sufficient funds
for any appraisal of the REO Property, the proper operation, management and
maintenance of the related REO Property, including, without limitation, the
creation of reasonable reserves for repairs, replacements, necessary capital
improvements and other related expenses and such other costs and expenses
described in the second preceding paragraph above.  In the event the Special
Servicer shall be retaining funds in the REO Account pursuant to the preceding
provision, then the REO Account shall satisfy clause (x) of the definition of
Eligible Account.  The Special Servicer shall notify the Master Servicer on or
prior to the related Determination Date of all expected

                                       62
<PAGE>
 
remittances (and the REO Account Mortgage Loans to which the deposits relate) to
be made to the Master Servicer by the Special Servicer for deposit into the
Collection Account on the next Special Servicer Remittance Date.

          SECTION 3.11.  SALE OF SPECIALLY SERVICED MORTGAGE LOANS AND REO
                         -------------------------------------------------
                         PROPERTIES.
                         ---------- 

          Subject to the requirements provided in the following paragraph, the
Special Servicer may purchase any Specially Serviced Mortgage Loan or any REO
Property being specially serviced by it (in each case at the Purchase Price
therefor) and may offer to sell to any Person (including any Operating Advisor
or any Certificateholder) any such Specially Serviced Mortgage Loan or REO
Property, but in any event, shall so offer to sell any such Specially Serviced
Mortgage Loan or REO Property no later than the time determined by the Special
Servicer to be sufficient to result in the sale of such Specially Serviced
Mortgage Loan or REO Property on or prior to the purchase date specified in
Section 3.15. The Special Servicer shall give the Trustee, the Master Servicer
and the Operating Advisor, if any, not less than five Business Days' prior
written notice of its intention to (i) purchase any such Specially Serviced
Mortgage Loan or REO Property or (ii) offer for sale any such Specially Serviced
Mortgage Loan or REO Property at auction or other manner consistent with the
Servicing Standard set forth in Section 3.01. In connection with the sale of any
Specially Serviced Mortgage Loan or REO Property, the Special Servicer shall
accept the highest cash bid received from any Person (including any
Certificateholder) for any such Specially Serviced Mortgage Loan or REO Property
in an amount at least equal to the Purchase Price therefor (after deducting
allocable expenses).

          In the absence of a bid in an amount at least equal to the Purchase
Price (after deducting allocable expenses), the Special Servicer shall accept
the highest bid received from any Person other than the Master Servicer, Special
Servicer or Operating Advisor, if any, that the Special Servicer determines to
be a fair price for the Specially Serviced Mortgage Loan or REO Property.
However, the Special Servicer may be the purchaser of a Specially Serviced
Mortgage Loan or a related REO Property only if the price at which the Special
Servicer purchases is at least equal to the highest bid and it has received at
least three bids from non-affiliated parties. Notwithstanding anything to the
contrary herein, neither the Trustee, in its individual capacity, nor any of its
Affiliates may bid for or purchase any Specially Serviced Mortgage Loan or any
REO Property. The Special Servicer shall not accept a bid from Wells Fargo Bank,
National Association unless such bid is in the good faith judgment of the
Special Servicer, equal to (and not greater than) the then market value of such
REO Property or the fair price of the Specially Serviced Mortgaged Loan.

          Unless so directed by the Operating Advisor, if any, the Special
Servicer shall not be obligated by either of the foregoing paragraphs or
otherwise to accept the highest cash bid if the Special Servicer determines, in
accordance with the Servicing Standard, that rejection of such bid would be in
the best interests of the Certificateholders. In addition, the Special Servicer
may accept a lower bid (including a bid lower than the Purchase Price) of a
Person other than an Interested Person or the Operating Advisor, if any, if it
determines, in accordance with the Servicing Standard, that acceptance of such
bid would be in the best interests of the Certificateholders (for example, if
the prospective buyer making the lower bid

                                       63
<PAGE>
 
is more likely to perform its obligations, or the terms offered by the
prospective buyer making the lower bid are more favorable), provided, that if
                                                            --------         
any Specially Serviced Mortgaged Loan or REO Property as to which an Appraisal
Reduction has occurred is to be sold by the Special Servicer, then the Special
Servicer shall not, without the approval of the Operating Advisor, if any,
accept any bid for such loan or property that is less than 90% of the appraised
value of the related Mortgaged Property (based on the appraisal used in
determining the related Appraisal Reduction).  The Special Servicer, after
consultation with the Operating Advisor, if any, shall determine no later than
six months prior to the end of the two-year period referred in Section 3.15 with
respect to any REO Property whether a sale of such REO Property pursuant to any
bids being made with respect thereto is in the best economic interests of the
Certificateholders as a whole.  If the Special Servicer so determines, after
consultation with the Operating Advisor, if any, that such a sale would not be
in the best interests of the Certificateholders, the Special Servicer shall seek
an extension of such two-year period in the manner described in Section 3.15.

          In determining whether any bid received from an Interested Person or
whether the price to be paid by the Special Servicer or any Affiliate thereof
represents a fair price or market value for any Specially Serviced Mortgage Loan
or any REO Property, the Special Servicer may rely conclusively on the opinion
of the value of such REO Property by an independent MAI designated appraiser at
the expense of the Trust Fund. In determining whether any bid constitutes a fair
price or market value for any Specially Serviced Mortgage Loan or any REO
Property, the Special Servicer shall take into account, among other factors, the
period and amount of any delinquency on the affected Specially Serviced Mortgage
Loan, the physical condition of the related Mortgaged Property or such REO
Property, the state of the local economy and the Trust Fund's obligation to
dispose of any REO Property within the two-year period specified in Section
3.15.

          Subject to the provisions of Section 3.15, 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 applicable Specially
Serviced Mortgage Loan or REO Property, including the collection of all amounts
payable in connection therewith. Any sale of any Specially Serviced Mortgage
Loan or REO Property shall be without recourse to, or representation or warranty
by, the Trustee, the Depositor, the Master Servicer, the Special Servicer or the
Trust Fund (except that any contract of sale and assignment and conveyance
documents may contain customary warranties of title, so long as the only
recourse for breach thereof is to the Trust Fund), and, if consummated in
accordance with the terms of this Agreement, none of the Master Servicer, the
Special Servicer, the Depositor or the Trustee shall have any liability to the
Trust Fund or any Certificateholder with respect to the purchase price therefor
accepted by the Special Servicer or the Trustee.

          The proceeds of any sale after deduction of the expenses of such sale
incurred in connection therewith shall be deposited within one Business Day in
the Collection Account in accordance with Section 3.08, and the Trustee, upon
receipt of such proceeds, and a Request for Release substantially in the form of
Exhibit K hereto, shall release or cause to be released to the Special Servicer
- ---------                                                                      
the related Trustee Mortgage File and Servicer Mortgage File and shall execute
and deliver such instruments of transfer or assignment, in each case without
recourse, as are provided by the Special Servicer and as shall be necessary to
vest in the

                                       64

applicable purchaser any Specially Serviced Mortgage Loan or REO Property sold
or transferred pursuant hereto.

          SECTION 3.12.  PERMITTED WITHDRAWALS FROM THE COLLECTION ACCOUNT.
                         ------------------------------------------------- 

          The Master Servicer may, from time to time make withdrawals from

     been previously reimbursed by the Special Servicer), the Fiscal Agent, or
     the Trustee and the Special Servicer in that order, for Advances, including
     accrued interest on such Advances at the Advance Rate from the date each
     such Advance was made until the same is reimbursed to the Master Servicer,
     the Special Servicer, the Fiscal Agent or the Trustee pursuant to this
     Section 3.12, such right of reimbursement pursuant to this subclause (b)
     being limited to amounts received in respect of particular Mortgage Loans
     (including, for this purpose, Insurance Proceeds, Liquidation Proceeds,
     amounts representing proceeds of other insurance policies, if any, covering
     the related Mortgaged Property, rental and other income from REO Property
     and proceeds of any purchase or repurchase of the related Mortgage Loan);
     provided, however, that any such Advances made pursuant to Section 3.26 or
     --------  -------           
     in connection with a defaulted Mortgage Loan that the Special Servicer does
     not foreclose on pursuant to the provisions of the last paragraph of
     Section 3.15 may be reimbursed from any other amounts in the Collection
     Account; and provided, further, that any Advance made of any attorney's
                  --------  -------       
     fees or other expenses incurred in connection with its activities pursuant
     to Section 3.15 and described in clause (d) of the definition of Realized
     Loss may be reimbursed from any amounts on deposit in the Collection
     Account;

               (c) to pay to the Master Servicer the Servicing Fee, to the
     extent that such amount was not previously paid to or retained by the
     Master Servicer, and any additional servicing compensation payable to it
     and to pay to the Special Servicer the Special Servicer Compensation (to
     the extent not otherwise retained by the Special Servicer) and any
     additional servicing compensation payable to it;

               (d) to reimburse the Master Servicer or the Special Servicer, as
     the case may be, from Liquidation Proceeds for Liquidation Expenses and to

     from Liquidation Proceeds and, after a Final Recovery Determination, from
     Insurance Proceeds, the amount of any unpaid Servicing Fee or Special
     Servicing Fee together with interest thereon at the Advance Rate with
     respect to the related Mortgage Loan;

               (e) to pay to the Seller, the Master Servicer or the Trustee, as
     the case may be, with respect to each Mortgage Loan or property acquired in

                                       65
<PAGE>
 
     thereof that has been or is being purchased pursuant to Sections 2.01,
     2.02, 2.03, 3.11 or 10.01 hereof, all amounts received thereon subsequent
     to the date of such purchase and not taken into account in determining the
     Purchase Price of such repurchased Mortgage Loan;

               (f)  to pay or reimburse the Trustee, the Master Servicer, the
     Special Servicer, the Fiscal Agent or the Depositor for expenses including
     interest accrued thereon at the Advance Rate of the Trust Fund incurred by
     and reimbursable to such Persons pursuant to the terms hereof (including
     Additional Trust Fund Expenses) and Special Servicer Compensation (to the
     extent not already paid) payable to the Special Servicer from the Trust
     Fund hereunder; provided, however, that with respect to Additional Trust
                     --------  -------     
     Fund Expenses, such Expenses may be paid on a monthly basis.

               (g)  to make payments to the Trustee for deposit in the
     Distribution Account in the amounts, and in the manner, specified in this
     Agreement;

               (h)  to withdraw any amount deposited in the Collection Account
     pursuant to Section 3.08 and not required to be deposited therein; and

               (i)  to clear and terminate the Collection Account upon

          The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account pursuant to such subclauses (a) through
(h) above.  The Master Servicer may apply Liquidation Proceeds and Insurance
Proceeds received with respect to a particular Mortgage Loan to reimbursements
permitted by clauses (b) and (d) above with respect to such Mortgage Loan first
to the Trustee, then to the Fiscal Agent, then to the Special Servicer and
finally to the Master Servicer.

          On or prior to each Servicer Remittance Date, the Master Servicer
shall withdraw from the Collection Account and remit to the Trustee, in

previously remitted by the Master Servicer but subsequently determined to be a
Nonrecoverable Advance, together with any Prepayment Premiums received prior to
the related Determination Date.

          The Master Servicer shall pay to the Special Servicer, the Trustee or
the Fiscal Agent from the Collection Account amounts permitted to be paid to the
Special Servicer, the Fiscal Agent or the Trustee therefrom promptly upon
receipt of a certificate of the Special Servicer Officer, a Responsible Officer
of the Trustee or a Responsible Officer of the Fiscal Agent, as the case may be,
describing the item and amount to which the Special Servicer, the Trustee or the
Fiscal Agent, as the case may be, is entitled.  The Master Servicer may rely
conclusively on any such certificate and shall have no duty to re-calculate the
amounts stated therein.  The Special Servicer shall keep and maintain separate
accounting on a Mortgage

                                       66
<PAGE>
 
Loan by Mortgage Loan basis, for the purpose of justifying any request made by
it for any withdrawal from the Collection Account.

          The Trustee, the Fiscal Agent, the Master Servicer and the Special
Servicer shall in all cases have a right prior to the Certificateholders to any
funds on deposit in the Collection Account from time to time for the payment of,
in the case of the Master Servicer, the Servicing Fee payable to the Master
Servicer hereunder, in the case of the Special Servicer, the Special Servicer
Compensation payable to the Special Servicer, in the case of the Trustee, the
amounts payable to the Trustee hereunder and in the case of the Fiscal Agent,

from amounts on deposit in the Collection Account pursuant to this Agreement.

          SECTION 3.13.  MAINTENANCE OF HAZARD INSURANCE AND OTHER INSURANCE.
                         --------------------------------------------------- 

          Subject to the limitations set forth below, the Master Servicer shall
use reasonable efforts consistent with the Servicing Standard to cause the
related Mortgagor to maintain for each Mortgage Loan (other than any REO Account
Mortgage Loan), and if the related Mortgagor does not so maintain, the Master
Servicer shall cause to be maintained, to the extent the Trustee has an
insurable interest, (a) standard hazard insurance with extended coverage in an
amount that is at least equal to the lesser of (i) the full replacement cost of
improvements securing such Mortgage Loan or Specially Serviced Mortgage Loan, as
the case may be, or (ii) the outstanding principal balance of such Mortgage Loan
and (b) any other insurance coverage for a Mortgage Loan which the related
Mortgagor is required to maintain under the related Mortgage, provided the
                                                              --------    
Master Servicer shall not be required to maintain earthquake insurance on any
Mortgaged Property.  The Special Servicer shall maintain for each REO Property
standard hazard insurance with extended coverage in amount that is at least
equal to the full replacement cost of improvements on the related REO Property
and any other insurance coverage for such Mortgage Loan which the related
Mortgagor is required to maintain under the related Mortgage, provided the
                                                              --------    
Special Servicer shall not be required to maintain earthquake insurance on any
REO Property.

          Each policy of standard hazard insurance maintained with respect to
any Mortgaged Property that is not an REO Property shall contain, or have an
accompanying endorsement that contains, a standard mortgagee clause.  If the
Mortgaged Property is located in a federally designated special flood hazard
area, the Master Servicer (with respect to any Mortgaged Property that is not an
REO Property) or the Special Servicer (with respect to any REO Property), as the
case may be, shall cause flood insurance to be maintained.  Such flood insurance
shall be in an amount equal to the lesser of (i) the unpaid Principal Balance of
the related Mortgage Loan or (ii) the maximum amount of such insurance available
for the related Mortgaged Property under the national flood insurance program,
if the area in which such Mortgaged Property is located is participating in such
program.

                                       67
<PAGE>
 
Pursuant to Section 3.08 hereof, 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 property thus
acquired or amounts released to the Mortgagor in accordance with the terms of
the applicable Mortgage Loan) shall be deposited in the Collection Account.

          Any cost incurred by the Master Servicer or the Special Servicer in
maintaining any insurance pursuant to this Section 3.13 shall not, for the
purpose of calculating monthly distributions to the Certificateholders or
remittances to the Trustee for their benefit, be added to the Principal Balance
of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so
permit.  Such costs shall be paid as a Property Protection Advance by the Master
Servicer or the Special Servicer, as the case may be, subject to Section 5.02
hereof.

          The Master Servicer and the Special Servicer shall conclusively be
deemed to have satisfied their obligations as set forth in the first paragraph
of this Section 3.13 either (i) if the Master Servicer or the Special Servicer,
as the case may be, shall have obtained and maintained a master force placed or
blanket insurance policy insuring against hazard losses on all of the applicable
Mortgage Loans serviced by it, it being understood and agreed that such policy
may contain a deductible clause on terms substantially equivalent to those
commercially available and maintained by comparable servicers consistent with
the Servicing Standard, and provided that such policy is issued by a Qualified
Insurer or (ii) the Master Servicer or the Special Servicer, as the case may be,
so long as the long-term rating of such person is not less than "BBB" (or an
equivalent rating) by S&P and D&P, if rated by D&P, self-insures for its
obligations as set forth in the first paragraph of this Section 3.13.  In the
event that the Master Servicer or the Special Servicer, as applicable, shall
cause any Mortgage Loan to be covered by such a master force placed or blanket
insurance policy, the incremental cost of such insurance allocable to such
Mortgage Loan (i.e., other than any minimum or standby premium payable for such
policy whether or not any Mortgage Loan is then covered thereby), if not borne
by the related Mortgagor, shall be paid by the Master Servicer as a Property
Protection Advance other than with respect to any REO Property which shall be
paid by the Special Servicer as a Property Protection Advance.  If such policy
contains a deductible clause, the Master Servicer or the Special Servicer, as
the case may be, shall, if there shall not have been maintained on the related
Mortgaged Property a policy complying with this Section 3.13 and there shall
have been a loss that would have been covered by such policy, deposit in the
Collection Account the amount not otherwise payable under such master force
placed or blanket insurance policy because of such deductible clause to the
extent that such deductible exceeds (i) the deductible under the related
Mortgage Loan or (ii) if there is no deductible limitation required under the
Mortgage Loan, the deductible amount with respect to insurance policies
generally available on properties similar to the related Mortgaged Property
which is consistent with the Servicing Standard, and deliver to the Trustee an
Officer's Certificate describing the calculation of such amount.  In connection
with its activities as administrator and servicer of the Mortgage Loans, each of
the Master Servicer and the Special Servicer agrees to present, on their
respective behalf and on behalf of the Depositor and the Trustee, claims under
any such master force placed or blanket insurance policy.

                                       68
<PAGE>
 
          With respect to each Mortgage Loan (other than REO Account Mortgage
Loans), the Master Servicer shall maintain accurate records with respect to each
related Mortgaged Property reflecting the status of taxes, assessments and other
similar items that are or may become a lien on the related Mortgaged Property
and the status of insurance premiums payable with respect thereto.  From time to
time, the Master Servicer (other than with respect to REO Account Mortgage
Loans) shall (i) obtain all bills for the payment of such items (including
renewal premiums), and (ii) effect payment of all such bills, taxes and other
assessments with respect to such Mortgaged Properties prior to the applicable
penalty or termination date, in each case employing for such purpose Escrow
Payments as allowed under the terms of the related Mortgage Loan.  If a
Mortgagor fails to make any such payment on a timely basis or collections from
the Mortgagor are insufficient to pay any such item before the applicable
penalty or termination date, the Master Servicer in accordance with the
Servicing Standard shall use its best efforts to pay as a Property Protection
Advance the amount necessary to effect the payment of any such item unless (x)
the Master Servicer reasonably anticipates that such item will be paid by the
Mortgagor by the close of business on or before the applicable penalty or
termination date, but in any event the Master Servicer, shall make such Advance
(subject to clause (y) below) within five Business Days after the Master
Servicer, has received confirmation that such item has not been timely paid;
                                                                            
provided, however, in the case of insurance premiums, if the Master Servicer
- --------  -------                                                           
does not have a master force placed or blanket insurance policy, the Master
Servicer shall make such advance on or before the termination date of the policy
relating to such premium, or (y) the Master Servicer determines in its good
faith business judgment that such Advance would be a Nonrecoverable Advance.
The Master Servicer shall be entitled to reimbursement of Advances, with
interest thereon at the Advance Rate, that it makes pursuant to the preceding
sentence from amounts received on or in respect of the related Mortgage Loan as
to which such Advance was made or if such Advance has become a Nonrecoverable
Advance, to the extent permitted by Section 3.12 of this Agreement; provided
                                                                    --------
that with respect to Specially Serviced Mortgage Loans on which the Master
Servicer has made such Advances, the Special Servicer will, on a monthly basis,
on the Special Servicer Remittance Date reimburse the Master Servicer for such
Advances, including interest accrued thereon at the Advance Rate pursuant to
Article V hereof.  With respect to REO Account Mortgage Loans, the Special
Servicer, the Trustee and the Fiscal Agent shall have the same duties to make
Property Protection Advances as the Master Servicer does as provided above.  No
costs incurred by the Master Servicer, the Trustee, the Fiscal Agent or the
Special Servicer, as the case may be, in effecting the payment of taxes and
assessments on the Mortgaged Properties and related insurance premiums shall,
for the purpose of calculating distributions to Certificateholders, be added to
the Principal Balance of the Mortgage Loans, notwithstanding that the terms of
such Mortgage Loans so permit.

          SECTION 3.14.  ENFORCEMENT OF DUE-ON-SALE CLAUSES; ASSUMPTION
                         ----------------------------------------------
                         AGREEMENTS.
                         ---------- 

          (a)   Except with respect to the one time assignment of any Mortgage
Loan in accordance with the terms of the related Mortgage Note and as referred
to below, when any Mortgaged Property has been or is requested to be conveyed by
the Mortgagor, the Master Servicer unless it has received written consent of the
Special Servicer to the contrary (which consent shall not unreasonably be
withheld and which consent or denial thereof shall

                                       69
<PAGE>
 
be provided by the Special Servicer within ten Business Days of its receipt of a
request for such consent from the Master Servicer; provided that the Special
Servicer's failure to respond to such request within ten Business Days shall be
deemed to be its consent to such request) or, if the related Mortgage Loan is a
Specially Serviced Mortgage Loan, the Special Servicer, shall, to the extent
that it has knowledge of such conveyance, enforce any due-on-sale clause
contained in the related Mortgage Loan in accordance with the Servicing Standard
and, to the extent permitted under the related Mortgage Loan and applicable law
and governmental regulations, but only to the extent that such enforcement will
not adversely affect or jeopardize coverage under any Required Insurance Policy.
It is understood that the Mortgage Loans generally permit the Mortgagors to make
a one time assignment of the related Mortgage Loan in connection with a sale of
the related Mortgaged Property.  In such an event, the Master Servicer, in
accordance with the Servicing Standard, may permit such assignment upon payment
by the Mortgagor of an assumption fee not to exceed one percent (1%) of then
outstanding principal balance of the Mortgage Loan and if the proposed purchaser
meets the Master Servicer's then current underwriting criteria for mortgage
loans comparable to such Mortgage Loan.  The Master Servicer agrees that in the
event its then current underwriting criteria is materially changed from its now
existing underwriting criteria, it will apply the more stringent guidelines.  If
enforcement of the due-on-sale clause is not possible for the reasons set forth
in the first sentence of this paragraph, the Master Servicer or Special
Servicer, as the case may be, shall, in accordance with Section 3.14(b), take or
enter into an assumption and modification agreement from or with the person to
whom such property has been or is about to be conveyed, pursuant to which such
person becomes liable under the Mortgage Loan, provided that the Mortgage Loan
shall continue to be covered (if so covered before the Master Servicer or the
Special Servicer, as the case may be, enters such agreement) by the applicable
Required Insurance Policies.  Each of the Master Servicer with the Special
Servicer's written consent to the extent required above (which consent shall not
unreasonably be withheld and which consent or denial thereof shall be provided
by the Special Servicer within ten Business Days of its receipt of a request for
such consent from the Master Servicer; provided that the Special Servicer's
failure to respond to such request within ten Business Days shall be deemed to
be its consent to such request) and the Special Servicer, as the case may be,
subject to Section 3.14(b), is also authorized to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as Mortgagor and
becomes liable under the Mortgage Loan.  Except as provided in this Section
3.14(a) or Section 3.14(b), the terms of the Mortgage Loan shall not be changed
unless the Mortgage Loan is in default or default with respect thereto is
reasonably foreseeable.  Notwithstanding the foregoing, neither the Master
Servicer nor the Special Servicer, as the case may be, shall be deemed to be in
default under this Section 3.14(a) by reason of any transfer or assumption.

          (b)   Subject to the Master Servicer's or the Special Servicer's, as
the case may be, duty to enforce any due-on-sale clause to the extent set forth
in Section 3.14(a) hereof in any case in which a Mortgaged Property has been
conveyed by a Mortgagor, if an assumption is to be made under Section 3.14(a)
and the Person to whom the conveyance is made is to enter into an assumption
agreement or modification agreement or supplement to the Mortgage Loan that
requires the signature of the Trustee, or if an instrument of release signed by
the Trustee is required releasing the Mortgagor from liability on the Mortgage

                                       70
<PAGE>
 
Loan, the Master Servicer or the Special Servicer, as the case may be, shall
deliver or cause to be delivered to the Trustee for signature the assumption
agreement with the Person to whom the Mortgaged Property is to be conveyed and
such modification agreement or supplement to the Mortgage Loan as are reasonable
or necessary to carry out the terms of the Mortgage Loan or otherwise to comply
with any applicable laws regarding assumptions or the transfer of the Mortgaged
Property to such Person.  The Trustee for the benefit of the Certificateholders
shall execute any necessary instruments in the form presented to it for such
assumption or substitution of liability.  Upon the closing of the transactions
contemplated by such documents, the Master Servicer or the Special Servicer, as
the case may be, shall cause the originals of the assumption agreement, the
release (if any), or the modification or supplement to the Mortgage Loan to be
delivered to the Trustee except to the extent such documents have been submitted
to the recording office, in which event the Master Servicer or the Special
Servicer, as the case may be, shall promptly deliver copies of such documents to
the Trustee.  Any fee collected by the Master Servicer or the Special Servicer,
as the case may be, for entering into an assumption or substitution of liability
agreement will be retained by the Master Servicer or the Special Servicer, as
the case may be, as additional servicing compensation.

          SECTION 3.15.  REALIZATION UPON SPECIALLY SERVICED MORTGAGE LOANS.
                         -------------------------------------------------- 

          Subject to Section 3.30 hereof, the Special Servicer shall foreclose
upon or otherwise comparably convert the ownership of properties securing such
of the Specially Serviced Mortgage Loans as come into and continue in default
and as to which, (a) in the reasonable judgment of the Special Servicer, no
satisfactory arrangements can, in accordance with the Servicing Standard, be
made for collection of delinquent payments pursuant to Section 3.01 hereof and
(b) such foreclosure or other conversion is deemed necessary or advisable by the
Special Servicer and is in its reasonable judgment in the best interests of the
Certificateholders as a whole.  In connection with such foreclosure or other
conversion, the Special Servicer shall follow such practices and procedures that
are consistent with the Servicing Standard, as satisfy the requirements of
subsection (b) of the immediately preceding sentence (to the extent applicable).

          If any Mortgaged Property becomes an REO Property, the Special
Servicer shall promptly notify the Trustee of such event, specifying the date as
of which any Mortgaged Property became an REO Property.  Pursuant to its efforts
to sell such REO Property, the Special Servicer shall either itself or through
an agent selected by the Special Servicer protect and conserve such REO Property
in accordance with the Servicing Standard and may, incident to its conservation
and protection of the interests of the Certificateholders, rent the same, or any
part thereof, as the Special Servicer deems to be in the interest of the
Certificateholders for the period prior to the sale of such REO Property.  The
terms of sale of any REO Property shall, subject to this Agreement, be in the
sole discretion of the Special Servicer.  The Special Servicer or the Master
Servicer shall be under no obligation to finance the sale of any REO Property
but may in its discretion do so with the same rights as it would have if it were
not the Special Servicer or the Master Servicer.

          Notwithstanding Section 3.01 hereof, the Trust Fund shall not acquire
any real property (or personal property incident to such real property) except
in connection with a

                                       71
<PAGE>
 
default or imminent default of a Mortgage Loan.  In the event that the Trust
Fund acquires any real property (or personal property incident to such real
property) in connection with a default or imminent default of a Mortgage Loan,
such property shall be disposed of by the Special Servicer within two years
after its acquisition by the Special Servicer for the Trust Fund, unless (i) the
Special Servicer on behalf of the Trust Fund has applied for an extension of
such two-year period pursuant to Sections 856(e)(3) and 860G(a)(8)(A) of the
Code, in which case the Special Servicer shall dispose of such REO Property
within the applicable extension period or (ii) the Special Servicer provides to
the Trustee an Opinion of Counsel, which shall be obtained at the expense of the
Trust Fund to the effect that the holding by the Trust Fund of such Mortgaged
Property for more than two years after its acquisition will not result in the
imposition of taxes on "prohibited transactions" as defined in Section 860F of
the Code with respect to the Tier 1 REMIC or Tier 2 REMIC or cause the Tier 1
REMIC or Tier 2 REMIC to fail to qualify as a REMIC at any time that any
Certificates are outstanding.  The Special Servicer shall manage, conserve,
protect and operate each such property for the Certificateholders solely for the
purpose of its prompt disposition and sale in a manner which does not cause such
property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) or result in the receipt by any REMIC of any "income from
non-permitted assets" within the meaning of Section 860F(a)(2)(b) of the Code or
any "net income from foreclosure property" which is subject to taxation under
the REMIC Provisions except with the prior written consent of the Master
Servicer.

          The income earned from the management of any Mortgaged Properties
acquired through foreclosure or other judicial proceeding on behalf of the
Certificateholders, net of reimbursement to the Special Servicer for expenses
incurred (including any taxes) in connection with such management, Advances made
by the Master Servicer, the Special Servicer, the Fiscal Agent or the Trustee in
connection with the related Mortgage Loan or REO Property and Liquidation
Expenses incurred by the Special Servicer in connection with the related
Mortgage Loan, shall be applied to the payment of principal of and interest on
the related Specially Serviced Mortgage Loans (with interest accruing and
principal amortizing as though such Mortgage Loans were still current) and all
such net income shall be deemed, for all purposes in this Agreement, to be
payments on account of principal of and interest on the related Mortgage Notes,
and shall be deposited into the related REO Account and transferred to the
Collection Account in accordance with Section 3.10.

          Prior to obtaining a deed as a result of or in lieu of foreclosure, or
otherwise acquiring (or causing the Trustee to acquire) possession of or title
to any Mortgaged Property, the Special Servicer shall obtain a preliminary
"Phase I" environmental assessment of such Mortgaged Property (the
"Environmental Assessment") prepared by an entity or person which regularly
conducts environmental assessments and which or whom has all necessary licenses
required by applicable law and has at least five years of experience conducting
such assessments.  All costs and expenses incurred by the Special Servicer in
connection with such Environmental Assessments shall be paid by the Special
Servicer as a Property Protection Advance.  Such Environmental Assessment shall
contain information upon which the Special Servicer or Operating Advisor could
determine whether there are any circumstances or conditions present at such
Mortgaged Property relating to the use, management or disposal of any Hazardous
Materials or for which investigation, testing, monitoring, containment, clean-up
or remediation could, in the judgment of the Special

                                       72
<PAGE>
 
Servicer, be required under any Environmental Law which, in either event,
materially and adversely affects the value of the Mortgaged Property
(collectively, "Environmental Conditions").  If an Environmental Assessment
reveals any Environmental Conditions, the Special Servicer shall send copies of
the Environmental Assessment to the Depositor, the Trustee, the Master Servicer
and the Operating Advisor, and, subject to Section 3.30, shall perform such
additional environmental testing in accordance with the Servicing Standard, to
establish satisfaction of the Environmental Conditions or to proceed in
accordance with this section (such additional testing is also an "Environmental
Assessment").

          Subject to Section 3.30 hereof, if the Environmental Assessment
establishes the existence of any Environmental Condition and the Special
Servicer believes that it is in the best economic interest of the Trust Fund to
proceed against such Mortgaged Property and, if title thereto is acquired, to
take such remedial, corrective or other action with respect to the unsatisfied
condition or conditions as may be prescribed by applicable law to satisfy such
condition or conditions, the Special Servicer shall so notify the Trustee and
the Master Servicer and proceed against such property.  The cost of any
remedial, corrective or other action contemplated hereby shall be an expense of
the Trust Fund and reimbursed pursuant to Section 3.12(f) hereof, and none of
the Special Servicer, the Master Servicer or the Trustee shall be required to
expend its own funds or otherwise incur any financial liability in connection
with any such action.

          If (i) an Environmental Assessment establishes the existence of any
Environmental Condition with respect to any Mortgaged Property and (ii) either
(A) the Special Servicer believes based upon the Environmental Assessment that
it is not in the best economic interest of the Trust Fund to proceed against
such Mortgaged Property or (B) either (1) the Trustee or (2) the Operating
Advisor has notified the Special Servicer in writing of its objection to the
Special Servicer's intentions to proceed against such Mortgaged Property within
five Business Days of receiving notice thereof, then the Special Servicer shall
take such other action as it deems to be in the best economic interest of the
Trust Fund (other than proceeding against the Mortgaged Property or directly or
indirectly becoming the operator thereof) as determined in accordance with the
Servicing Standard, and is hereby authorized at such time as it deems
appropriate to release such Mortgaged Property from the lien of the related
Mortgage.

          If the Special Servicer takes any action with respect to the use,
management, remediation or disposal of any Hazardous Materials on any Mortgaged
Property, the Special Servicer shall (i) inform each Rating Agency, the
Depositor, the Trustee, the Master Servicer and the Operating Advisor of the
commencement and progress of any such action; and (ii) take such action in
compliance with all applicable Environmental Laws.

          If the Special Servicer determines not to foreclose or otherwise
realize upon a Specially Serviced Mortgage Loan pursuant to this Section 3.15
(except as a result of a modification or a restructuring), the Special Servicer
shall so notify the Depositor, the Master Servicer, the Operating Advisor, each
Rating Agency, the Fiscal Agent and the Trustee and shall take such other action
as may be required to maximize the net present value of such Mortgage Loan.

satisfaction and discharge in full of any Specially Serviced Mortgage Loan) will
be escrowed in a manner customary for such purposes, and upon notification by
the Master Servicer or the Special Servicer, as the case may be, in the form of
a certification (which certification shall include a statement to the effect
that all amounts received or to be received in connection with such payment
which are required to be deposited in the Collection Account have been or will
be so deposited) of a Servicing Officer and a request for release of the Trustee
Mortgage File in the form of Exhibit K hereto the Trustee shall promptly release

Servicer, as the case may be, and the Trustee shall execute and deliver to the
Master Servicer or the Special Servicer, as the case may be, the deed of
reconveyance or release, satisfaction or assignment of mortgage or such
instrument releasing the lien of the Mortgage, as directed by the Master
Servicer or the Special Servicer, as the case may be, together with the Mortgage
Note with written evidence of cancellation thereon.  The provisions of the
immediately preceding sentence shall not, in any manner, limit or impair the
right of the Master Servicer or the Special Servicer, as the case may be, to
execute and deliver, on behalf of the Trustee, the Depositor, the
Certificateholders or any of them, any and all instruments of satisfaction,
cancellation or assignment, or of partial or full release or discharge and all
other comparable instruments, with respect to the Mortgage Loans, and with
respect to the Mortgaged Properties held for the benefit of the
Certificateholders.  No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Distribution
Account but shall be paid by the Master Servicer or the Special Servicer, as the
case may be, except to the extent that such expenses are paid by the related
Mortgagor in a manner consistent with the terms of the related Mortgage and
applicable law.  From time to time and as shall be appropriate for the servicing
or foreclosure of any Mortgage Loan, including for such purpose, collection
under any policy of flood insurance, any fidelity bond or errors or omissions
policy, or for the purposes of effecting a partial or total release of any
Mortgaged Property from the lien of the Mortgage or the making of any
corrections to the Mortgage Note or the Mortgage or any of the other documents
included in the Trustee Mortgage File, the Trustee shall, upon request of the
Master Servicer or the Special Servicer, as the case may be, and the delivery to
the Trustee of a Request for Release signed by a Servicing Officer, in the form
of Exhibit K hereto, release the Trustee Mortgage File to the Master Servicer or

the Special Servicer, as the case may be.

          If the Special Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any related Mortgaged Property, the Special Servicer
shall deliver to the Trustee, for signature as appropriate, any court pleadings,
requests for trustee's sale or other documents necessary to effectuate such
foreclosure or any legal action brought to obtain judgment against the Mortgagor
on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to
enforce any other remedies or rights provided by the Mortgage Note or the
Mortgage or otherwise available at law or in equity, together with a certificate

Servicer and the Special Servicer shall transmit to the Trustee, to the extent
required by this Agreement, all documents and instruments coming into the
possession of the Master Servicer and the Special Servicer from time to time and
shall account fully to the Trustee for any funds received or otherwise collected
thereby, including Liquidation Proceeds or Insurance Proceeds in respect of any
Mortgage Loan.  All Servicer Mortgage Files or Trustee Mortgage Files and funds
collected or held by, or under the control of, the Master Servicer or the

the Trustee, subject to the applicable provisions of this Agreement.  The Master
Servicer and the Special Servicer also agree that they shall not create, incur

payable to the Master Servicer and the Special Servicer, as applicable, under
this Agreement.

          SECTION 3.18.  SERVICING COMPENSATION.

from amounts held in the Collection Account pursuant to subclauses (c) and (d)

and customarily paid by borrowers, the Special Servicer shall use reasonable
good faith efforts to collect such amounts from the related Mortgagor, and to
the extent so collected, in full or in part, the Special Servicer shall not be
entitled to compensation for the portion so collected therefor hereunder out of
the Trust Fund.

for each monthly period ending on each Distribution Date shall be reduced by an
amount equal to the Compensating Interest (if any) for such Distribution Date.

Distribution Account (but only to the extent of the net investment earnings, if
any, with respect to each such account), and, (iii) to the extent not required

earned on deposits in the Reserve Account.

with the Servicing Standard, the Special Servicer may agree to any modification,
waiver or amendment of any term of any related Specially Serviced Mortgage Loan
without the consent of the Master Servicer, the Trustee, the Fiscal Agent, the

                                            --------  -------          
Operating Advisor shall have the power to approve the action of the Special

any term of any Mortgage Loan except as provided in this Agreement.

          (b)    Subject to the provisions of this Section 3.26, the Master
Servicer may agree to any modification, waiver or amendment of any non-Money
Term of a Mortgage Loan that is not a Specially Serviced Mortgage Loan to cure
any ambiguity therein or to correct or supplement any provisions therein that
may be inconsistent with any other provision therein or which may be necessary
to protect and preserve the lien of the related

Certificateholder.

          (c)    All modifications, waivers or amendments of any Mortgage Loan
effected by the Master Servicer or the Special Servicer, as the case may be,
shall be in writing.  The Special Servicer shall not agree to any modification,
amendment or waiver of any Mortgage Loan unless it determines, in its sole
judgment, such modification would increase on a net present value basis the
proceeds of such Mortgage Loan that would be paid to, or recovered by, the Trust
Fund over the amounts that would be paid to, or recovered by, the Trust Fund
without such modification, amendment or waiver; provided that the Special
                                                --------                 
Servicer shall not agree to any modification with respect to any Mortgage Loan
that would (i) reduce the Mortgage Rate of any Mortgage Loan; (ii) increase the
Mortgage Rate, reduce or increase the principal balance (except for reductions
resulting from actual payments of principal) or change the final maturity date
of such Mortgage Loan unless the related Mortgagor is in default with respect to
the Mortgage Loan or, in the judgment of the Special Servicer, such default is
reasonably foreseeable; (iii) cause an Adverse REMIC Event; (iv) extend the
maturity date of any Mortgage Loan later than two years prior to the Final Rated
Distribution Date; (v) permit deferral of interest without accrual of interest
at the Mortgage Interest Rate thereon; or (vi) result in the amount of negative
amortization added to the principal balance of such Mortgage Loan resulting from
such modification exceeding 10% of the principal balance of such Mortgage Loan
(less any negative amortization added to the principal balance of such Mortgage
Loan prior to such modification).

          (d)    Subject to the restrictions of paragraph (c) above, in the case
of a Specially Serviced Mortgage Loan, the Special Servicer may, with the
consent of the Operating Advisor, if any is required, pursuant to Section 3.29,
in accordance with the Servicing Standard, without the consent of the Trustee or
any Certificateholder, do the following:

           (i)   The Special Servicer may, from time to time, adjust the
     payment schedule for the Mortgage Loan, including extending the due dates
     for Monthly Payments and changing the amount of Monthly Payments.

          (ii)   The Special Servicer may from time to time (A) reduce the
     amounts owing under any such Mortgage Loan by forgiving principal and/or
     forgiving interest accrued on such Mortgage Loan and/or late fees or
     penalties and/or (B) reduce or increase the Monthly Payments on any such
     Mortgage Loan (including by reducing or increasing the Principal Balance,
     extending or reducing the amortization term or maturity date or reducing
     the Monthly Payment thereof).

         (iii)   The Special Servicer may from time to time permit the
     Mortgagor to pledge additional collateral for the Mortgage Loan; provided,
                                                                      -------- 
     however, that (1) the Special Servicer shall have requested and received an
     -------                                                                    
     Opinion of Counsel (obtained at the expense of the Trust Fund and
     reimbursable pursuant to Section 3.12(f) to the extent not paid or
     reimbursed by the Mortgagor) to the effect that any such additional pledge
     of collateral is permitted hereby, will not cause the Mortgage Loan to
     cease to be a Qualified Mortgage and will not cause an Adverse REMIC Event;
     and (2) the

                                       81
<PAGE>
 
     Special Servicer shall not permit the Mortgagor to pledge any real property
     collateral pursuant to this Section 3.26 unless the Special Servicer shall
     have first determined in accordance with the Servicing Standard, based upon
     an Environmental Assessment conducted by an independent person in
     accordance with Section 3.15 at the expense of the Mortgagor or Trust Fund,
     that such additional collateral is in compliance with applicable
     Environmental Laws and/or that there are no circumstances present with
     respect to such additional 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 effective Environmental Laws, or, if any such containment, clean-
     up or remediation is required, that adequate funds therefor have been
     placed in escrow with the Master Servicer or the Special Servicer, as the
     case may be, by or on behalf of the Mortgagor.  Any additional collateral
     pledged pursuant to this paragraph may be subsequently released by the
     Special Servicer if the Special Servicer determines that the release is in
     the best interests of the Certificateholders as a whole.

               (iv)   The Special Servicer may from time to time permit the
     Mortgagor to substitute collateral for all or a portion of the Mortgaged
     Property or may release part of the Mortgaged Property; provided, however,
                                                             --------  ------- 
     that (1) after giving effect to such substitution or release of collateral,
     (A) the ratio of the outstanding principal balance of the Mortgage Loan to
     the appraised value of the substituted Mortgaged Property, as appraised by
     an MAI-certified appraiser in accordance with MAI standards (engaged at the
     expense of the Trust Fund and reimbursable pursuant to Section 3.12(f), to
     the extent not paid for by the related Mortgagor) as of a date no earlier
     than 180 days prior to the date of the substitution or release, shall be no
     greater than, and the Debt Service Coverage Ratio shall be no less than,
     that of the Mortgaged Property immediately prior to such substitution or
     release of collateral and (B) any substitute collateral shall consist of a
     fee interest in real property improved by a multifamily or commercial
     structure; (2) the Special Servicer shall have requested and received an
     Opinion of Counsel (obtained at the expense of the Trust Fund to the extent
     not paid or reimbursed by the Mortgagor) to the effect that any such
     substitution or release of collateral is permitted hereby, will not cause
     the Mortgage Loan to cease to be a Qualified Mortgage and will not cause an
     Adverse REMIC Event; (3) the Special Servicer shall not permit the
     Mortgagor to substitute any real property collateral pursuant to this
     Section 3.26 unless the Special Servicer shall have first determined in
     accordance with the Servicing Standard, based upon an Environmental
     Assessment conducted by an independent person in accordance with Section
     3.15 at the expense of the Mortgagor, that such substitute collateral is in
     compliance with applicable Environmental Laws and that there are no
     circumstances present with respect to such substitute 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 effective Environmental Law, or, if any
     such containment, clean-up or remediation is required, that adequate funds
     therefor have been placed in escrow with the Master Servicer or the Special
     Servicer by or on behalf of the Mortgagor and (4) such substitution will
     not, in and of itself, result in the rating of the Certificates being
     reduced below the

                                       82
<PAGE>
 
     then-current rating on the Certificates, as evidenced in writing by the
     Rating Agencies.

          (e)    In the event the Special Servicer intends to permit a Mortgagor
to substitute collateral for all or any portion of a Mortgaged Property as
permitted by Section 3.26(d)(iv) or pledge additional collateral for the
Mortgage Loan as permitted by Section 3.26(d)(iii), if the security interest of
the Trust Fund in such collateral would be perfected by possession, or if such
collateral requires special care or protection, then prior to agreeing to such
substitution or addition of collateral, the Special Servicer shall make
arrangements for such possession, care or protection, and prior to agreeing to
such substitution or addition of collateral (or such arrangement for possession,
care or protection) shall obtain the prior written consent of the Trustee with
respect thereto (which consent shall not be unreasonably withheld, delayed or
conditioned); provided, however, that the Trustee shall not be required (but has
              --------  -------                                                 
the option to) to consent to any substitution or addition of collateral or to
hold any such collateral which will require the Trustee to undertake any
additional duties or obligations or incur any additional expense.

          (f)    The Master Servicer or the Special Servicer may require, in its
discretion, as a condition to granting any request by a Mortgagor for any
consent, modification, extension, waiver or amendment, that such Mortgagor pay
to the Master Servicer or the Special Servicer a reasonable and customary
modification fee to the extent permitted by law.  The Master Servicer or the
Special Servicer shall charge the Mortgagor for any costs and expenses incurred
by the Master Servicer or the Special Servicer in connection with any request
for a modification, extension, waiver or amendment unless the Master Servicer or
the Special Servicer determines that the Mortgagor cannot reasonably afford such
costs and expenses, but the failure or inability of the Mortgagor to pay any
such costs and expenses shall not impair the right of the Master Servicer or the
Special Servicer to cause such costs and expenses, and interest thereon at the
Advance Rate, to be paid or reimbursed by the Trust Fund pursuant to Section
3.12(f).

          (g)    The Master Servicer or the Special Servicer shall notify the
Trustee of any modification, waiver, extension or amendment of any term of any
Mortgage Loan and the date thereof, and shall deliver to the Trustee for deposit
in the related Mortgage File, an original counterpart of the agreement relating
to such modification, waiver or amendment, promptly following the execution
thereof except to the extent such documents have been submitted to the
applicable recording office, in which event the Master Servicer or the Special
Servicer, as the case may be, shall promptly deliver copies of such documents to
the Trustee.

records stored electronically on computer tapes, discs and the like) relating to
the Mortgage Loan in the possession of the Master Servicer and reasonably
requested by the Special Servicer to enable it to assume its duties hereunder

shall continue to act as Master Servicer and administrator of such Mortgage Loan
until the Special Servicer has commenced the servicing of such Mortgage Loan,
which shall occur upon the receipt by the Special Servicer of the information,
documents and records referred to in the preceding sentence.  With respect to
each Mortgage Loan that becomes a Specially Serviced Mortgage Loan, the Master
Servicer shall instruct the related Mortgagor to continue to remit all payments
in respect of such Mortgage Loan to the Master Servicer.  The Master Servicer
shall give written notice to the Special Servicer within one Business Day after
receiving any collections made to the Master Servicer with respect to the
Specially Serviced Mortgage Loans.  Within one Business Day after receiving such
notice, the Special Servicer shall give written notice to the Master Servicer
with instructions on how to apply such collections.  Within one Business Day
after receiving such instructions, the Master Servicer shall use its best
efforts to apply such collections in accordance with the Special Servicer's
instructions.  The Special Servicer Compensation shall accrue from the Due Date
preceding the date the Special Servicer has commenced the servicing of such
Mortgage Loan.  Upon any Mortgage Loan becoming a Specially Serviced Mortgage
Loan, the Special Servicer shall, within 30 days, pay to the Master Servicer all
outstanding Advances including accrued interest thereon with respect to such
Specially Serviced Mortgage Loan to the extent such amounts are not Non-
recoverable Advances and the amounts paid by the Special Servicer to the Master
Servicer shall then be deemed to be Advances of the Special Servicer.

          Upon determining that a Specially Serviced Mortgage Loan (other than
an REO Account Mortgage Loan) has become current and has remained current for
three consecutive Monthly Payments, and upon determining that no other Servicing
Transfer Event has occurred and is continuing with respect thereto, the Special
Servicer shall promptly give notice thereof to the Master Servicer, the Trustee
and the Operating Advisor, if any, and the Special Servicer shall promptly
deliver to the Master Servicer (but in no event more than 5 Business Days after
delivery of such notice to the Master Servicer), all information, documents and
records (including records stored electronically on computer tapes, magnetic
discs and the like) relating to such Mortgage Loan in its possession.  Upon
delivering such information and documents to the Master Servicer and upon giving
such notice: (i) such Mortgage Loan shall cease to be a Specially Serviced
Mortgage Loan, (ii) the Special Servicer's obligation to service such Mortgage
Loan shall terminate, and (iii) the obligations of the Master Servicer to
service and administer such Mortgage Loan shall resume (such Mortgage Loan is
referred to as a "Corrected Mortgage Loan").

          (b)    In servicing any Specially Serviced Mortgage Loan, the Special
Servicer shall provide to the Trustee originals of such documents included
within the definition of "Trustee Mortgage File" which are in the Special
Servicer's possession or were created by the Special Servicer for inclusion in
the related Mortgage File (with a copy of

                                       84
<PAGE>
 
each such original to the Master Servicer) and copies of any additional related
Mortgage Loan information, including correspondence with the related Mortgagor.

          (c)    On or prior to each Determination Date, the Special Servicer
shall deliver promptly to the Master Servicer all reports and information in the
Special Servicer's possession relating to the Specially Serviced Mortgage Loans
and REO Properties as the Master Servicer reasonably requests to enable it to
perform its responsibilities under this Agreement.

          (d)    Notwithstanding the provisions of subsection (c) of this
Section 3.27, the Master Servicer shall maintain ongoing payment records with
respect to each Specially Serviced Mortgage Loan and shall provide the Special
Servicer with any information in the Master Servicer's possession (or reasonably
available to it) reasonably required by the Special Servicer to perform its
duties under this Agreement.

          SECTION 3.28.  LIMITATION ON LIABILITY OF OPERATING ADVISOR AND THE
                         ----------------------------------------------------
                         SPECIAL SERVICER.
                         ---------------- 

          The Operating Advisor shall only have the right to approve certain
actions of the Special Servicer and shall have no liability to the Trust Fund or
the Certificateholders for any action by the Special Servicer taken, or not
taken, upon the good faith approval or disapproval by the Operating Advisor in
accordance with this Agreement, and the Operating Advisor shall have no such
liability for errors in judgment.

          SECTION 3.29.  APPROVAL BY THE OPERATING ADVISOR.
                         --------------------------------- 

          The Special Servicer shall advise the Operating Advisor, if any, [and
the Master Servicer] in a written report (in reasonable detail) if the Special
Servicer proposes to take any of the actions listed below in clauses (a) through
(e) with respect to an applicable Specially Serviced Mortgage Loan, and the
Special Servicer shall not take any such action which the Operating Advisor
disapproves of in writing except in order to comply with applicable law.  If the
Operating Advisor has not disapproved (in a writing delivered to the Special
Servicer) a proposed action of the Special Servicer within five Business Days
after the date of the delivery of the notice to the Operating Advisor of such
proposed action, the Special Servicer may take actions it specifically
recommended.  The Special Servicer shall seek the approval of the Operating
Advisor in respect of the matters set forth in clauses (i) through (vi) of
Section 3.30 to the extent applicable, prior to the Special Servicer taking any
of the following actions:

          (a)    any foreclosure upon or comparable conversion (which may
     include acquisition of an REO Property) of the ownership of properties
     securing such of the Specially Serviced Mortgage Loans as come into and
     continue in default;

          (b)    any modification of a Money Term of a Specially Serviced
     Mortgage Loan or any extension of the maturity date of a Specially Serviced
     Mortgage Loan;

                                       85
<PAGE>
 
          (c)    any sale of a Specially Serviced Mortgage Loan or REO Property
     (other than upon termination of the Trust Fund pursuant to Section 10.01);

          (d)    any determination to bring an REO Property into compliance with
     Environmental Laws; and

          (e) any release of collateral or acceptance of substitute or
     additional collateral for a Mortgage Loan.

          The Operating Advisor in its good faith business judgment may refuse
to approve, by written notice to the Special Servicer, the recommendations of
the Special Servicer based solely upon (1) the present value analysis used in
the report of the Special Servicer and (2) the Operating Advisor's assessment of
the likelihood of success under the Special Servicer's proposed course of
action.  In the event the Operating Advisor refuses to approve the Special
Servicer's recommendations, the Special Servicer shall give written notice to
the Trustee within five Business Days.  If the Special Servicer's recommendation
is not approved by the Operating Advisor, an independent third party arbitrator
selected by the Trustee in its sole discretion (with written notification of
such selection to be delivered promptly to the Special Servicer and Operating
Advisor), within 10 days and subject to written confirmation that such
appointment would not result in a downgrading or withdrawal of the then-current
rating of any Certificate and who shall be required to acknowledge in writing
the acceptance of its appointment and its agreement to serve as such arbitrator,
will determine whether the proposed action of the Special Servicer is in the
best economic interests of the Trust Fund.  Expenses incurred by and fees due to
the independent arbitrator shall be borne by the Holders of the Class of
Certificates then entitled to appoint the Operating Advisor.  Any agreement for
the retention of an independent arbitrator shall provide that such independent
arbitrator will be responsible for (i) selecting a course of action based solely
on the recommendations provided by the Operating Advisor and the Special
Servicer, and (ii) providing a decision within five Business Days of hearing
such recommendations with respect to the related subject matter.  Pending a
decision of the independent arbitrator, the Special Servicer shall not take the
action in question.  The recommendation referred to in clause (i) of the
preceding sentence shall be submitted to the arbitrator by the Special Servicer
and the Operating Advisor within one Business Day after the selection of the
arbitrator by the Trustee.

          SECTION 3.30.  SPECIAL SERVICER REPORTS AND RECOMMENDATIONS.
                         -------------------------------------------- 

          Prior to taking any of the actions set forth in clauses (a) through
(e) of Section 3.29 with respect to a Specially Serviced Mortgage Loan, the
Special Servicer shall make reports and recommendations and provide analyses in
reasonable detail, to the extent applicable, with respect to the following
matters, to the Operating Advisor:

               (i)   whether the foreclosure upon or other comparable conversion
     (including the acquisition of an REO Property) of the ownership of
     properties securing such of the Mortgage Loans as have come into and
     continue in default and as to which no satisfactory arrangements can be
     made for collection of delinquent

                                       86
<PAGE>
 
     payments pursuant to Section 3.26 would, consistent with the Servicing
     Standard, be in the best economic interest of the Trust Fund;

              (ii)   whether, if the Special Servicer proceeds with a
     foreclosure in accordance with the laws of the state where a Mortgaged
     Property is located, in the judgment of the Special Servicer, a deficiency
     judgment should or should not be sought because the likely recovery if a
     deficiency judgment is obtained will or will not be sufficient to warrant
     the cost, time, expense and/or exposure of pursuing such deficiency
     judgment;

             (iii)   whether the waiver or enforcement of any due-on-sale
     clause or due-on-encumbrance clause contained in a Specially Serviced
     Mortgage Loan is in the economic interest of the Trust Fund in accordance
     with the Servicing Standard;

               (iv)  in connection with the taking or entering into of an
     assumption agreement from or with a person to whom a Mortgaged Property
     relating to a Specially Serviced Mortgage Loan has been or is about to be
     conveyed, or the releasing of the original Mortgagor from liability upon a
     Specially Serviced Mortgage Loan and substituting of a new Mortgagor,
     whether the credit status of the prospective new Mortgagor is in compliance
     with the Special Servicer's regular commercial mortgage origination or
     Servicing Standard and criteria consistent with the Servicing Standard;

                (v)  in connection with a decision by the Operating Advisor as
     to whether or not title to a Mortgaged Property should be obtained by the
     Trust Fund as a result of or in lieu of foreclosure or otherwise, or to
     otherwise acquire possession of, or take any other action with respect to,
     any Mortgaged Property if, as a result of any such action, to the knowledge
     of the Special Servicer, the Trustee, for the Trust Fund or the
     Certificateholders or the Special Servicer 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
     other Environmental Law, determine, based upon an Environmental Assessment,
     (A) whether such Mortgaged Property is or is not in material compliance
     with applicable Environmental Laws (including those applicable to Hazardous
     Materials) and, if a determination is made that such Mortgaged Property is
     not in material compliance with such applicable Environmental Laws, whether
     it is in the economic interest of the Trust Fund to take such actions as
     are necessary to bring such Mortgaged Property in material compliance
     therewith or (B) whether there are any circumstances present at such
     Mortgaged Property relating to the use, management, presence or disposal of
     any Hazardous Materials for which investigation, testing, monitoring,
     containment, clean-up or remediation could be reasonably required under any
     currently effective applicable Environmental Law and, if a determination is
     made that such Hazardous Materials are present for which actions could be
     required, whether it would be in the economic interest of the Trust Fund,
     consistent with the Servicing Standard, to take such actions with respect
     to the containment, clean-up or remediation of Hazardous Materials
     affecting such Mortgaged Property pursuant to or as required by
     Environmental Law (setting forth the basis for the Special Servicer's

                                       87
<PAGE>
 
     determination, and the estimated cost to the Trust Fund of such proposed
     action, including any Property Protection Advances); and

               (vi)   with respect to any proposed modification, waiver or
     amendment of a Mortgage Loan or substitution of collateral by the Mortgagor
     pursuant to Section 3.26(d), whether such course of action is reasonably
     likely to produce a greater recovery on a net present value basis than
     liquidation of such Mortgage Loan, setting forth the basis on which the
     Special Servicer made such determination, including the status of any
     existing material default or the grounds for concluding that a payment
     default is reasonably foreseeable.

          SECTION 3.31.  APPRAISAL REDUCTIONS.
                         -------------------- 

          Within 45 days of the earliest to occur of (a) the date on which a
change in the Mortgage Rate, principal balance, payment rate or amortization
terms (each, a "Money Term") or in the stated maturity of any Specially Serviced
Mortgage Loan becomes effective as a result of a modification of such Mortgage
Loan by the Special Servicer, (b) 90 days after the date on which an uncured
delinquency occurs in respect of a Mortgage Loan, (c) 60 days after the date on
which a receiver is appointed in respect of a Mortgaged Property (if such
appointment remains in effect during such 60 day period) or (d) as soon as
reasonably practical after the date on which a Mortgaged Property becomes an REO
Property, the Special Servicer shall advise the Trustee, the Fiscal Agent and
the Master Servicer of such occurrence of such event, and, unless an appraisal
has been conducted within the twelve months preceding such event, will obtain an
appraisal (which may be an update of a prior appraisal) (the cost of which shall
be an Additional Trust Fund Expense and reimbursable pursuant to Section
3.12(f)) satisfying the requirements for such appraisals contained in Section
3.10.  The Special Servicer will determine the appraised value of the related
Mortgaged Property on the basis of such appraisal and will report the same
promptly to the Master Servicer.  The Master Servicer will thereupon determine
and report to the Trustee and the Special Servicer the amount of any Appraisal
Reduction based upon such appraisal.

          In addition, upon the occurrence of any event giving rise to a
subsequent Appraisal Reduction (including the delinquency referred to in the
second proviso to the definition thereof) the Special Servicer will obtain an
       -------                                                               
appraisal (the cost of which shall be an Additional Trust Fund Expense and
reimbursable pursuant to Section 3.12) within 45 days of the occurrence of any
such event giving rise to a subsequent Appraisal Reduction and will adjust the
amount of the Appraisal Reduction in accordance therewith.  If the Master
Servicer or Special Servicer continues to make Advances in connection with such
Mortgage Loan, more than twelve months after an appraisal was obtained with
respect to an Appraisal Reduction, the Special Servicer will order a new
appraisal or update of the prior appraisal (the cost of which shall be an
Additional Trust Fund Expense and reimbursable pursuant to Section 3.12) and
will adjust the amount of the Appraisal Reduction in accordance therewith.

          An Appraisal Reduction related to a Mortgage Loan will be reduced to
zero as of the date such Mortgage Loan is paid in full, liquidated, repurchased
or otherwise disposed.  Notwithstanding the foregoing, an Appraisal Reduction
will be an amount equal to zero with respect to such a Mortgage Loan if (i) the
event giving rise to such Appraisal

                                       88
<PAGE>
 
Reduction is the extension of the maturity of such Mortgage Loan, (ii) the
payments on such Mortgage Loan (other than Balloon Payments) were not delinquent
during the twelve-month period immediately preceding such extension and (iii)
the payments on such Mortgage Loan are then current; provided, that if at any
later date there occurs a delinquency in payment with respect to such Mortgage
Loan, any subsequent Appraisal Reduction will be recalculated and applied to the
same extent as it would have been previously applied.  In addition, in any case,
upon the occurrence of any event giving rise to a subsequent Appraisal Reduction
(including the delinquency referred to in the immediately preceding sentence)
more than twelve months after an appraisal was obtained with respect to an
Appraisal Reduction, the Special Servicer will obtain a new appraisal as
described above, within 45 days of the occurrence of any such event giving rise
to a subsequent Appraisal Reduction and will adjust the amount of the Appraisal
Reduction in accordance therewith.

          With respect to each Mortgaged Property as to which an Appraisal
Reduction has occurred and which has become current and has remained current for
twelve consecutive Monthly Payments, and with respect to which no other
Servicing Transfer Event has occurred and is continuing, the Master Servicer
shall, within 30 days of the date of such twelfth Monthly Payment, order an
appraisal (which may be an update of a prior appraisal) (the cost of which shall
be an Additional Trust Fund Expense and reimbursable pursuant to Section 3.12).
Based upon such appraisal, the Master Servicer shall thereupon redetermine and
report to the Trustee the amount of the Appraisal Reduction with respect to such
Mortgaged Property.

          Each Appraisal Reduction shall become effective on the Distribution
Date (the "Appraisal Reduction Effective Date") in the month following the month
in which the Appraisal Reduction is calculated or recalculated as set forth in
the second proviso in the definition of "Appraisal Reduction", or pursuant to
the second and third preceding paragraphs.

          SECTION 3.32.  REPORTS TO THE SECURITIES AND EXCHANGE COMMISSION.
                         ------------------------------------------------- 

          The Depositor shall file with the Securities and Exchange Commission
(the "Commission"), within 15 days of the Delivery Date, a Current Report on
Form 8-K together with this Agreement and from time to time at the request of
the Master Servicer any report or other information provided to the Depositor by
the Master Servicer and requested to be filed with the Commission.

          The Trustee shall establish, on or prior to the Delivery Date, and

in the Trust Fund, the Distribution Account, into which the Trustee upon receipt
from the Master Servicer shall

amounts required to be remitted by the Depositor pursuant to the terms hereof.
All distributions to be made from time to time to Holders of interests in the
Trust Fund out of funds in the Distribution Account shall be made by or on
behalf of the Trustee.  The Trustee will give notice to the Master Servicer, the
Special Servicer, the Rating Agencies and the Depositor of the location of the
Distribution Account and of any change thereof, prior to the use thereof.  Funds
held in the Distribution Account which have been delivered to the Trustee
earlier than the Servicer Remittance Date prior to the next Distribution Date
shall be invested by the Trustee, to the extent practicable, in Eligible
Investments as directed in writing by the Master Servicer.  All income and gain
net of any losses realized from any such investment shall be for the benefit of
the Master Servicer as additional servicing compensation and shall be subject to
withdrawal by the Trustee for remittance to the Master Servicer at the Master
Servicer's direction from time to time.  The amount of any losses (net of any
gains) incurred in respect of any such investments shall be remitted by the
Master Servicer to the Trustee for deposit in the Distribution Account out of
the Master Servicer's own funds immediately as realized.

          The Trustee shall make, to the extent required or authorized
hereunder, withdrawals from the Distribution Account for the following purposes:

               (a)  to reimburse the Trustee for its expenses;

     Distribution Account and not required to be deposited therein;

               (d)  to make required distributions to the Certificateholders
     pursuant to Section 4.02;

               (e)  to pay any taxes imposed on the Trust Fund; and

               (f)  to clear and terminate the Distribution Account upon
     termination of this Agreement pursuant to Article X hereof.

          SECTION 4.02.  DISTRIBUTIONS.
                         ------------- 

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

     Regular Interest EFG), an amount

                                       90
<PAGE>
 
     equal to the interest accrued on the aggregate Uncertificated Principal
     Balance of such Class of Tier 1 REMIC Regular Interests at the Weighted
     Average Rate during the preceding Due Period, plus any unpaid portion of
     accrued interest for any prior period with interest thereon at a rate equal
     to the related Weighted Average Rate, reduced by the sum of (i) the amount
     of Prepayment Interest Shortfalls allocable to each such Class (in the same
     proportion as the corresponding Class or Classes of Certificates of the
     Tier 2 REMIC as provided in Section 4.05 herein) plus (ii) the amount of
     Deferred Interest allocable to each such Class or Classes (in the same
     proportion as the corresponding Class or Classes of Certificates of the
     Tier 2 REMIC as provided in Section 4.05 herein) plus (iii) the amount of
     Additional Trust Fund Expenses allocable to each such Class (in the same

     Capitalization Amount allocable to each such Class (in the same proportion

     to each Class A-1, Class A-2, Class B, Class C and Class D Uncertificated
     Tier 1 REMIC Regular Interest, the Prepayment Premiums to be distributed on

     Class R-I Certificate, all other amounts remaining in the Tier 1 REMIC;

provided, however, that notwithstanding the deemed distributions set forth in

clauses (A), (B), (C) and (D) above, distributions from the Distribution Account
shall only be made to the Holders of Certificates; and provided, further, that
                                                       --------  -------      
each Realized Loss, Additional Trust Fund Expense (to the extent attributable to
a Mortgage Loan), Appraisal Reduction and Prepayment Interest Shortfall, shall
be deemed allocated, and adjustments or distributions as a consequence thereof
shall be deemed made.

<PAGE>
 
          (b)  On each Distribution Date the Trustee shall apply amounts in the
Distribution Account to pay to the Holders of the Certificates, to the extent of
the Available Distribution Amount for such Distribution Date, as follows in the
following order of priority:

               (i)  to the Class A-1, Class A-2 and Class A-X Certificates, pro
     rata, in respect of interest, in an amount equal to the Interest
     Distribution Amount in respect of each such Class of Certificates for such
     Distribution Date and, to the extent not previously paid, for all prior
     Distribution Dates;

              (ii)  to the Class A-1 Certificates in reduction of their
     Certificate Principal Balance, the Principal Distribution Amount until the
     Certificate Principal Balance thereof has been reduced to zero;

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

     Certificate Principal Balance, the remaining Principal Distribution Amount
     until the Certificate Principal Balance thereof has been reduced to zero;

             (xii)  to the Class F Certificates in respect of interest, in an
     amount equal to the Interest Distribution Amount in respect of such Class

     Certificate Principal Balance, the remaining Principal Distribution Amount
     until the Certificate Principal Balance thereof has been reduced to zero;

             (xiv)  to the Class G Certificates in respect of interest, in an
     amount equal to the Class G Interest Distribution Amount in respect of such
     Class of Certificates for such Distribution Date, and to the extent not

              (xv)  to the Class G Certificates, in reduction of their

          (e) The Trustee shall be responsible for the calculations with respect
to distributions from the Distribution Account and the determination of
Certificate Principal Balances based upon the information furnished to it by the
Master Servicer pursuant to Section 3.19 so long as the Trust Fund has not been
terminated in accordance with this Agreement; provided, however, that the
                                              --------  -------          
Trustee shall not be responsible for recomputing, recalculating or verifying
information provided by the Master Servicer.  All distributions made to
Certificateholders on any Distribution Date will be made to the
Certificateholders of record on the immediately preceding Record Date, except
for the final distribution on a Class, which shall be made only upon
presentation of the Certificate to the Trustee as provided for in the
Certificate.  All distributions made to the Certificateholders shall be based
upon the Percentage Interest represented by their respective Certificates.  If
following its receipt of a Master Servicer's report pursuant to Section 3.19,
the Trustee determines that

                                       93
<PAGE>
 
there are no Mortgage Loans outstanding and no other funds or assets in the
Trust Fund other than the funds in the Distribution Account or the Collection
Account, or if the Trustee otherwise determines that a final distribution will
be made on a Class of Certificates, the Trustee shall promptly send the final
distribution notice to each Certificateholder pursuant to Section 10.03
specifying the manner in which the final distribution will be made.

          (f)  Any Certificateholder shall be entitled to receive distributions
hereunder on a Distribution Date (other than as provided in Section 10.03
respecting the final distribution) by wire transfer to the account specified in
writing by the Certificateholder to the Trustee if the Initial Certificate
Principal Balance evidenced by such Holder's Certificate is at least equal to
$5,000,000 or 100% of the aggregate Initial Certificate Principal Balance of all
Certificates of like Class, except with respect to the Class A-X Certificates,
if the holder thereof holds at least 100% Percentage Interests of such Class.
In each case, the account must be specified in writing at least five Business
Days prior to the Record Date for the Distribution Date on which wire transfers
will commence.  All other distributions shall be made by check payable to the
Certificateholder mailed by first class mail to the address of such
Certificateholder reflected in the Certificate Register.

          (g)  Notwithstanding any other provision of this Agreement, Excess
Prepayment Interest and other penalties shall be payable to the Master Servicer
as additional compensation.

          SECTION 4.03.  ALLOCATION OF REALIZED LOSSES, ADDITIONAL TRUST FUND
                         ----------------------------------------------------
                         EXPENSES AND APPRAISAL REDUCTIONS.
                         --------------------------------- 

          (a)  Prior to each Distribution Date, the Trustee shall, based on the
information furnished to the Trustee by the Master Servicer or the Special
Servicer, as applicable, pursuant to Section 3.19, determine the total of
Realized Losses and Additional Trust Fund Expenses, if any, incurred with
respect to the Mortgage Loans during the previous Prepayment Period.  On each
Distribution Date, such Realized Losses and Additional Trust Fund Expenses will
be allocated (without duplication) as follows:

               (i)   Realized Losses of interest and Additional Trust Fund
     Expenses which have been reimbursed will be allocated (and in each case
     will reduce the interest payable) (A) first, to the Class G, Class F, Class
     E, Class D, Class C and  Class B Certificates, in that order in proportion
     to the interest payable thereon on such Distribution Date, and (B) second
     to the Class A-1, Class A-2 and Class A-X Certificates, pro rata, in
     proportion to the interest payable thereon on such Distribution Date (in
     each case in reduction of the interest payable thereon); and

               (ii)  Additional Trust Fund Expenses which have been reimbursed
     and which exceed amounts received or advanced with respect to such
     Distribution Date on account of interest and Realized Losses attributable
     to principal on the Mortgage Loans will be allocated to the Class G, Class
     F, Class E, Class D, Class C and Class B, in that order, and then to the
     Class A-1 and Class A-2 Certificates, pro rata (in each case by reducing
     the principal balance thereof by the amount so

                                       94
<PAGE>
 
     allocated), until the Certificate Principal Balances of each such Class has
     been reduced to zero.

Realized Losses and Additional Trust Fund Expenses allocated to any Class of
Certificates shall be allocated among the Certificates of such Class on a pro
rata basis in accordance with the Percentage Interest represented by each such
Certificate.

          (b)  If the Certificate Principal Balance of any Class of Certificates
has been reduced as a result of a Realized Loss with respect to a Mortgage Loan
and any recoveries or payments in respect of principal in excess of the
Principal Balance of such Mortgage Loan are subsequently received by the Master
Servicer or the Special Servicer, then on the next Distribution Date such excess
payments or recoveries shall be included in the Principal Distribution Amount
and distributed in accordance with Section 4.02(b).

          (c)  On each Distribution Date, the Trustee shall, based on the
information furnished to the Trustee by the Master Servicer or the Special
Servicer, as applicable, apply the aggregate Appraisal Reduction incurred with
respect to the Mortgage Loans during the previous Due Period.  On each
Distribution Date, such Appraisal Reductions will be allocated (after the
allocation of Realized Losses and Additional Trust Fund Expenses described in
Section 4.03(a)), to the Certificate Principal Balance of the most subordinated
Class of Certificates that would otherwise receive distributions of interest.

With respect to each Class of Certificates as to which a more senior Class of
Certificates is outstanding, the Interest Distribution Amount otherwise
distributable on such Distribution Date to such subordinated Class of
Certificates to which an Appraisal Reduction is allocated on such Distribution
Date will be reduced by the related Appraisal Reduction Capitalization Amount,
and such amount will be added to the Certificate Principal Balance of such Class
of Certificates to the extent actually paid by the related Mortgagor.

Certificateholders Report (in the form attached as Exhibit S hereto).  In
                                                   ---------             
addition, the Trustee shall forward to each Certificateholder, the Depositor,
the Underwriters, each Rating Agency and each beneficial holder of a
Certificate, the Monthly Reports as are provided to the Trustee by the Master
Servicer pursuant to Section 3.19 or Section 3.22 and the Special Servicer
pursuant to Section 3.22.

          (b)  Not later than May 30 of each year, the Trustee shall cause to be
forwarded by mail to each Certificateholder, the Special Servicer, the Seller,
the Operating Advisor, the Depositor, the Underwriters, and each Rating Agency a
copy of the Annual Reports furnished to the Trustee by the Master Servicer
substantially in the form of

                                       95

Exhibit P.  The Trustee will make copies of the Annual Reports available to each
- ---------                                                                       
Certificateholder and each Beneficial Holder providing satisfactory evidence of
ownership of such Certificate or ownership of a beneficial interest in a
Certificate, as the case may be.

          (c)  The Trustee will provide to any Certificateholder upon request
the outstanding Certificate Principal Balance as of the most recent Distribution
Date. Upon the request of any Beneficial Holder of Certificates and upon
presentation of evidence of such ownership satisfactory to Trustee, the Trustee
shall provide to such Beneficial Holder any information which is provided to
Certificateholders.

          (d)  In addition to any other requirements set forth herein relating
to the provision of information to Certificateholders, the Trustee shall provide
to each Certificateholder and each Rating Agency, upon request thereof, such
additional documents relating to the Certificates and the Mortgage Loans as may
be requested by any Certificateholder in writing (subject to the Trustee either
having such documents in its possession or to receipt thereof from the Master
Servicer). The Trustee shall include a notice to such effect, together with the
first monthly statement (and on the monthly statement in each January
thereafter) delivered to each Certificateholder under Section 4.04(a) hereof.

          (e)  Notwithstanding any other provisions hereof, the Trustee, the
Master Servicer and the Special Servicer shall have no obligation to furnish
information in any instance which in their respective judgment could cause them
to incur any liability, including, without limitation, any liability arising out
of the violation of applicable federal or state securities laws, or could cause
it to incur any cost or expense for which it is not indemnified to its
reasonable satisfaction.  The Trustee, the Master Servicer and the Special
Servicer shall each be entitled at its option to require that recipients of such
information agree to such reasonable terms or conditions that are necessary in
their view to protect them against any such liability or to prevent any such
violation of applicable securities or other laws, or to provide indemnification
to the Trustee, the Master Servicer and the Special Servicer for any liability
or damage that may arise therefrom.

          (f)  The Trustee may add to or cause to be accompanied with any
information delivered pursuant to subsections (b), (c), (d), or (e) of this
Section 4.04 as well as pursuant to Sections 3.22(b), 3.23, 3.30, and 3.32, any
legend or disclaimer which the Trustee determines is reasonably appropriate or
necessary in its judgment, including, without limitation, the following legend:

          The [describe or identify information] has been prepared and furnished
               --------------------------------                                 
          by, or has been prepared based upon information furnished by, [the]
          [Master Servicer] [Depositor] [name Special Servicer], and the Trustee
          undertakes no responsibility for the accuracy or completeness of any
          such information or the sufficiency thereof for any particular
          purpose.  The Trustee has not independently investigated or verified
          any such information or the accuracy or completeness thereof, and
          makes no representation or warranty of any kind with respect thereto.
          The Trustee undertakes no obligation to update any such information in
          the future, or to disseminate or make available similar or other
          information in the future (except for any information which the
          Trustee is

          required to distribute under the express terms of the Pooling and
          Servicing Agreement).

          SECTION 4.05.  PREPAYMENT INTEREST SHORTFALLS; DEFERRED INTEREST.
                         ------------------------------------------------- 

          The Interest Distribution Amount for each applicable Class of
Certificates for each Distribution Date shall be reduced in the manner set forth
in the following sentence by Prepayment Interest Shortfalls (to the extent not
offset by Excess Prepayment Interest or a reduction of the Servicing Fee as
provided in Section 3.18(d)).  The Interest Distribution Amount for the Class A-
1, Class A-2, Class A-X, Class B, Class C, Class D, Class E, Class F and Class G
Certificates shall be reduced by Prepayment Interest Shortfalls (to the extent
not offset by Excess Prepayment Interest or a reduction of the Servicing Fee as
provided in Section 3.18(d)) pro rata based on the Interest Distribution Amount
for each such Class of Certificates that would have resulted absent such
reductions.

          On each Distribution Date on which the portion of the Available
Distribution Amount allocable to interest on the Mortgage Loans is insufficient
to pay interest accrued on the Certificates as a result of Deferred Interest on
Mortgage Loans, the amount of such Deferred Interest on Mortgage Loans will (i)
reduce the Interest Distribution Amount payable to the Holders of (and will be
added to the Certificate Principal Balance of) the Class G, Class F, Class E,
Class D, Class C and Class B Certificates, in that order and then to the Class
A-1 and Class A-2 Certificates, pro rata, in proportion to the respective
amounts of interest accrued thereon, and (ii) will be added to the Certificate
Principal Balances of the Class G, Class F, Class E, Class D, Class C, Class B,
Class A-1 and Class A-2 Certificates, to the extent of the reduction in the
Interest Distribution Amount payable to the holders of such Classes.

                                   ADVANCES

          SECTION 5.01.  MONTHLY ADVANCES.
                         ---------------- 

          Subject to the conditions of this Article V, the Master Servicer (or
the Special Servicer with respect to Specially Serviced Mortgage Loans), the
Trustee, as successor to the Master Servicer or Special Servicer, or the Fiscal
Agent as required shall make a Monthly Advance with respect to the Master
Servicer, to the Distribution Account, and with respect to the Special Servicer,
to the Collection Account in the amount, if any, of the aggregate Monthly
Payments (other than the principal portion of any Balloon Payment, but including
Assumed Scheduled Payments), after adjusting the interest portion of each such
Monthly Payment to the Net Mortgage Interest Rate, that were due on the Mortgage
Loans or Specially Serviced Mortgage Loans, as the case may be, on the Due Date
but that were not received and remitted to the Collection Account or the REO
Account by the close of business on the Determination Date preceding the
Servicer Remittance Date; provided, however, that the amount of any Monthly
                          --------  -------                                
Advance required to be made by the Master Servicer, the Special Servicer, the
Trustee, as successor to the Master Servicer or the Special Servicer, or the

                                       97
<PAGE>
 
Fiscal Agent, with respect to a Mortgage Loan as to which there has been an
Appraisal Reduction will be an amount equal to the product of (i) the amount
required to be advanced by the Master Servicer, or the Special Servicer, the
Trustee, as successor to the Master Servicer or the Special Servicer, or the
Fiscal Agent, without giving effect to this proviso and (ii) a fraction, the
numerator of which is the outstanding Principal Balance of such Mortgage Loan as
of the immediately preceding Determination Date less any Appraisal Reduction and
the denominator of which is the outstanding Principal Balance of the Mortgage
Loan as of such Determination Date.  Subject to the conditions of this Article
V, the Special Servicer shall make a Monthly Advance relating to Specially
Serviced Mortgage Loans no later than the Special Servicer Remittance Date to
the Collection Account maintained by the Master Servicer.  The Master Servicer
(or the Special Servicer with respect to Specially Serviced Mortgage Loans), the
Trustee or the Fiscal Agent, as applicable, shall be obligated to make any such
Monthly Advance only to the extent that such Advance will not be a
Nonrecoverable Advance.  The Master Servicer (or the Special Servicer with
respect to Specially Serviced Mortgage Loans), the Trustee or the Fiscal Agent,
as applicable, shall not make any Monthly Advance if such Person in its sole
discretion, and pursuant to Section 5.04, determines that such Monthly Advance
would be a Nonrecoverable Advance and such determination shall be conclusive and
binding on the Trustee and the Certificateholders.  Notwithstanding anything to
the contrary contained in this Agreement, (a) the Master Servicer (or the
Special Servicer with respect to Specially Serviced Mortgage Loans), the Trustee
or the Fiscal Agent, as applicable, shall have no obligation to advance any
Principal Prepayment or the final payment of principal due on a Balloon Loan
(whether upon maturity, acceleration or otherwise) required to be made in
connection with any Mortgage Loan, provided that the Master Servicer (and the
Special Servicer with respect to Specially Serviced Mortgage Loans) will make
Monthly Advances after the Maturity Date in accordance with the interest rate
provisions and the amortization schedule in effect prior to the applicable
maturity date if it does not deem such Monthly Advances to be a Nonrecoverable
Advance, and (b) the obligation of the Master Servicer (or the Special Servicer
with respect to Specially Serviced Mortgage Loans), the Trustee or the Fiscal
Agent, as applicable, to make Monthly Advances with respect to any Mortgage Loan
shall cease on the date upon which the Mortgage Loan becomes a Liquidated Loan.

          On the Determination Date immediately preceding the related
Distribution Date, the Master Servicer, the Trustee or the Fiscal Agent, as
applicable, shall determine whether and to what extent any Mortgagor has failed
to make any payment of principal or interest in respect of scheduled
installments of principal and interest that were due on the Due Date and
determine the Monthly Advances required for the related Distribution Date.  The
Master Servicer shall notify the Special Servicer on the Report Date of such
required Monthly Advance advances on Specially Serviced Mortgage Loans.  The
Master Servicer or Special Servicer (in case of Specially Serviced Mortgage
Loans) shall determine whether such Monthly Advances, if made by such Person
would be recoverable from Insurance Proceeds or Net Liquidation Proceeds or from
any other source of recovery on the related Mortgage Loan.  If the Master
Servicer (or the Special Servicer with respect to Specially Serviced Mortgage
Loans), the Trustee or the Fiscal Agent, as applicable, shall have determined
that it is not obligated to make the entire Monthly Advance because all or a
lesser portion of such Monthly Advance would be a Nonrecoverable Advance, the
Master Servicer (or the Special Servicer with respect to Specially Serviced
Mortgage Loans), the Trustee or

                                       98
<PAGE>
 
the Fiscal Agent, as applicable, shall deliver to the Trustee, not less than two
Business Days prior to the related Distribution Date, the Officer's Certificate
described in Section 5.04.

          In lieu of making all or a portion of any Monthly Advance, the Master
Servicer, the Trustee or the Fiscal Agent, as applicable may cause to be made an
appropriate entry in its records relating to the Collection Account that funds
in such account in excess of the Available Distribution Amount (less the amount
of such Monthly Advance) for the related Distribution Date have been used by the
Master Servicer, the Trustee or the Fiscal Agent, as applicable in discharge of
its obligation to make any such Monthly Advance.  Any funds so applied shall be
replaced by the appropriate party by deposit, in the manner set forth above, in
the Collection Account no later than the Servicer Remittance Date with respect
to the next succeeding Distribution Date to the extent that funds in the
Collection Account on such date are less than the amounts required to be
distributed to the Certificateholders on the related Distribution Date.  The
Master Servicer, the Special Servicer, the Trustee or the Fiscal Agent, as
applicable shall be entitled to be reimbursed from the Collection Account for
all Monthly Advances (including interest accrued thereon at the Advance Rate) of
its own funds made pursuant to this Section as provided in Section 3.12.

          SECTION 5.02.  OTHER ADVANCING OBLIGATIONS.
                         --------------------------- 

          (a)  Subject to the conditions of this Article V, the Master Servicer
or the Special Servicer with respect to Specially Serviced Mortgage Loans, as
applicable shall, after reasonable inquiry, make Property Protection Advances
from time to time, unless the Master Servicer or the Special Servicer, as
applicable, has made a good faith determination that such Advances (including
interest accrued thereon at the Advance Rate) would constitute Nonrecoverable
Advances.  The Master Servicer or the Special Servicer, as applicable, shall not
make any Property Protection Advance if it determines, in its sole discretion,
that such a Property Protection Advance would be a Nonrecoverable Advance and
such determination shall be conclusive and binding on the Trustee and the
Certificateholders.  All Property Protection Advances on Specially Serviced
Mortgage Loans made or to be made by the Master Servicer in connection with the
performance of its obligations under this Agreement shall, if paid by the Master
Servicer, be reimbursed by the Special Servicer on a monthly basis to the Master
Servicer, which payments and reimbursements shall be Property Protection
Advances of the Special Servicer.  On each Report Date, the Master Servicer
shall give the Special Servicer notice of the amount of such Advance.  If the
Master Servicer or the Special Servicer, as applicable shall make a good faith
determination that such advances would be a Nonrecoverable Advance, such Person
shall promptly deliver to the Trustee the Officer's Certificate described in
Section 5.04.  The Master Servicer, the Special Servicer, the Trustee or the
Fiscal Agent, as applicable shall be entitled to reimbursement for any such
Nonrecoverable Advance as provided in Section 3.12 hereof.

          (b)  The Special Servicer, as applicable shall make Property
Protection Advances with respect to any related Specially Serviced Mortgage
Loans, but only to the extent such Person determines that such Property
Protection Advance would not be a Nonrecoverable Advance; provided, however,
                                                          --------  ------- 
that the Master Servicer may continue to make Property Protection Advances with
respect to taxes and insurance on Specially Serviced Mortgage Loans to the
extent such Loans are not REO Account Mortgage Loans but only to

                                       99
<PAGE>
 
the extent that it determines such Property Protection Advance would not be a
Nonrecoverable Advance.  Such Advances are subject to monthly reimbursement by
the Special Servicer pursuant to the above paragraph.  The Special Servicer
shall promptly notify the Master Servicer if it determines that any Advance
would be Nonrecoverable Advance.

          SECTION 5.03.  PRIORITY FOR REIMBURSEMENT.
                         -------------------------- 

          The Master Servicer's and the Special Servicer's rights of
reimbursement (and the Trustee's or the Fiscal Agent's right of reimbursement to
the extent that the Trustee or the Fiscal Agent becomes subrogated to the rights
of the Master Servicer or the Special Servicer in the event that it makes a
Monthly Advance or Property Protection Advance or takes some other necessary
action because the Master Servicer or the Special Servicer, as applicable fails
to do so, with the rights of the Trustee and the Fiscal Agent to reimbursement
being senior to any right of the Master Servicer or the Special Servicer, as
applicable to reimbursement under this Agreement) for Advances and for other
amounts described in this Agreement shall be prior to the rights of the
Certificateholders to receive any amounts recovered with respect to such
Mortgage Loans.

          SECTION 5.04.  NONRECOVERABLE ADVANCES.
                         ----------------------- 

          The determination by the Master Servicer (or any other Person making
an Advance) that any proposed Monthly Advance or Property Protection Advance,
is, or if made, would be, a Nonrecoverable Advance, shall be evidenced by an
Officer's Certificate delivered to the Master Servicer, Trustee, the Fiscal
Agent and Special Servicer setting forth the reasons for such determination,
along with, to the extent such information, report or document is in such
Person's possession or known to be reasonably available at such time, including
any related income and expense statements, rent rolls, occupancy statements,
property improvement reports and copies of appraisals (prepared by an
independent MAI-certified appraiser in accordance with MAI standards within the
last 12 months on the Mortgaged Property), and, if such reports are used by such
Person to determine that any Monthly Advance or Property Protection Advance, as
applicable, would be a Nonrecoverable Advance, any engineers' reports,
environmental surveys or other information relevant thereto which support such
determination.  The determination by any such Person that any Advance would be a
Nonrecoverable Advance shall be conclusive and binding on the Trustee and the
Certificateholders.  Any independent determination by the Master Servicer,
Special Servicer, Trustee or the Fiscal Agent that any proposed Monthly Advance
or Property Protection Advance, if made, would constitute a Nonrecoverable
Advance shall be evidenced by an Officers' Certificate as described in this
Section 5.04.

          SECTION 5.05.  MONTHLY ADVANCE PROCEDURES.
                         -------------------------- 

          (a)  If, as of any Determination Date, the Master Servicer or Special
Servicer determines that a Monthly Advance is required in accordance with
Section 5.01, it shall so notify the Trustee, the Special Servicer and the
Fiscal Agent on the Report Date.  The Master Servicer shall make its Monthly
Advance on or before 1:00 p.m., New York time, on the Servicer Remittance Date
and the Special Servicer shall make its Monthly Advance on or before the Special
Servicer Remittance Date.  Any such Monthly Advances

                                      100
<PAGE>
 
shall be included with the distribution to the Certificateholders on the related
Distribution Date.

          (b)  If the Master Servicer or the Special Servicer, as the case may
be, fails to make a Monthly Advance required to be made pursuant to Section 5.01
on or before 5:00 p.m., New York time, on the Servicer Remittance Date, the
Trustee shall at or before 10:00 A.M., New York time on the related Distribution
Date, provide to the Master Servicer or the Special Servicer, as the case may
be, with a copy to the Fiscal Agent by telecopy, written notice of such failure
and the amount of such failure and that failure to remit the amount required
immediately will be an Event of Default.

          (c)  In the event that the Master Servicer or the Special Servicer, as
the case may be, as of noon New York time on the Servicer Remittance Date has
failed to fulfill its obligations hereunder to make any Monthly Advances (or to
make all or a portion of the remittance to the Trustee required pursuant to
Section 3.12(g)), the Trustee shall immediately notify the Master Servicer or
the Special Servicer, as the case may be, of its termination pursuant to Section
8.01 hereof and shall advance the amount necessary due to such failure by the
Master Servicer or the Special Servicer, as the case may be, such advance to be
considered a Monthly Advance for purposes hereof; and, with respect to any
Monthly Advance made by the Trustee, the Trustee shall have all of the rights
with respect to such Monthly Advances as the Master Servicer or the Special
Servicer, as the case may be, would have had if it had made the Monthly Advances
hereunder, including rights of reimbursement with interest at the Advance Rate
and rights to make the determination that a Monthly Advance is a Nonrecoverable
Advance in accordance with the provisions of Section 5.04 hereof (without regard
to any impairment of any such rights of reimbursement caused by such Master
Servicer's or Special Servicer's default in its obligations hereunder);
provided, however, that if Monthly Advances made by the Trustee, the Master
- --------  -------                                                          
Servicer and the Special Servicer shall at any time be outstanding, or any
amounts of interest thereon shall be accrued and unpaid, all amounts available
to repay such Monthly Advances and interest hereunder shall be applied entirely
to the amounts owing in respect of such Monthly Advances to the Trustee, until
such amounts shall have been repaid in full, before any repayment to the Master
Servicer and the Special Servicer.  The Fiscal Agent will make the Advance prior
to 1:00 p.m., New York time on the related Distribution Date only if the Trustee
fails to do so and, in such event, will be entitled to the same reimbursement as
the Trustee, the Special Servicer or Master Servicer, provided that the Fiscal
Agent's right to reimbursement shall be senior to that of the Trustee, the
Special Servicer and the Master Servicer.  Notwithstanding the foregoing
obligations of the Trustee and the Fiscal Agent to make any Monthly Advance
required to have been made by the Master Servicer or the Special Servicer but
not so made, the Trustee and the Fiscal Agent shall, each in addition to its
other rights hereunder, have the same right as the Master Servicer or the
Special Servicer under Sections 5.01 and 5.04 (subject to the requirements of
Section 5.04) to determine that such Monthly Advance, if made, would constitute,
or any Monthly Advance theretofore made constitutes, a Nonrecoverable Advance,
and the right to refuse to make such a Nonrecoverable Advance and to
reimbursement of any such Nonrecoverable Advance (to the extent made) with
interest thereon at the Advance Rate.

                                      101

          Each of the Trustee and the Fiscal Agent shall be entitled to
conclusively rely on any Officer's Certificate regarding a Nonrecoverable
Advance in connection with making any Advances hereunder.

                               THE CERTIFICATES

          SECTION 6.01.  THE CERTIFICATES.
                         ---------------- 

          The Certificates shall be in substantially the forms set forth in
                                                                           
Exhibits A-1, A-2, A-X, B, C, D, E, F, G, R-I, and R-II hereto, with such
- ------------  ---  ---  -  -  -  -  -  -  ---      ----                  
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Agreement or as may in the reasonable judgment of
the Trustee or the Depositor be necessary, appropriate or convenient to comply,
or facilitate compliance, with applicable laws, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with the rules of any securities exchange
on which any of the Certificates may be listed, or as may, consistently
herewith, be determined by the officers executing such Certificates, as
evidenced by their execution thereof.

          The Definitive Certificates shall be printed, typewritten,
lithographed or engraved or produced by any combination of these methods or may
be produced in any other manner permitted by the rules of any securities
exchange on which any of the Certificates may be listed, all as determined by
the officers executing such Certificates, as evidenced by their execution
thereof.

          The Class A-1, Class A-2, Class B, Class C and Class D Certificates
will be issued in fully registered form only in minimum denominations of
$100,000 and integral multiples of $1,000 in excess thereof.  The Class E, Class
F and Class G Certificates will be issued in fully registered form as Definitive
Certificates in minimum denominations of $100,000 and integral multiples of
$1,000 in excess thereof, provided, that one certificate of each Class, if
                          --------                                        
necessary, may be issued in a smaller amount so that the aggregate of each Class
of Certificates equals its respective aggregate Certificate Principal Balance.
The Class A-X Certificates will be issued in fully registered form as Definitive
Certificates in minimum percentage interests of 10% and integral multiples of
10% in excess thereof.  The Class R-I and Class R-II will be issued in fully
registered form in Definitive Certificates in each case in percentage interest
of 100%.

          The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by a Responsible Officer.  Certificates bearing the manual
or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall bind
the Trustee, notwithstanding that such individuals or any of them have ceased to
be so authorized prior to the authentication and delivery of such Certificates
or did not hold such offices at the date of such Certificate.  No Certificate
shall be entitled to any benefit under this Agreement, or be valid for any
purpose, unless there appears on such Certificate a certificate of
authentication executed by the Trustee

                                      102
<PAGE>
 
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 6.02.  REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.
                         ----------------------------------------------------- 

          (a)  The Trustee shall maintain, or cause to be maintained, a
Certificate Register in which, subject to such reasonable regulations as it may
prescribe, the Trustee shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided.  Upon surrender for
registration of transfer of any Certificate, the Trustee shall execute,
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates in like aggregate interest and of the
same Class.

          (b)  At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of authorized denominations and the same
aggregate interest in the Trust Fund and of the same Class, upon surrender of
the Certificates to be exchanged at the office or agency of the Trustee set
forth in Section 9.11.  Whenever any Certificates are so surrendered for
exchange, the Trustee shall execute, authenticate and deliver the Certificates
which the Certificateholder making the exchange is entitled to receive.  Every
Certificate presented or surrendered for registration of transfer or exchange
shall be accompanied by a written instrument of transfer in form satisfactory to
the Trustee and in compliance with the requirements of this Section 6.02 duly
executed by the Holder thereof or its attorney duly authorized in writing.

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

          (d)  All Certificates surrendered for registration of transfer and
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

          (e)  No transfer of any Class E, Class F, Class G, Class A-X or Class
R 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 which does not require such registration or qualification. In
the event that a transfer is to be made without registration or qualification,
either (i) the Trustee shall require that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee certify
to the Trustee in writing in the forms set forth in Exhibit L and Exhibit M,
                                                    ---------     --------- 
respectively, or such other form acceptable to the Trustee, as to the facts
surrounding the transfer or, (ii) if such certificates are not delivered the
Depositor or the Trustee shall require an Opinion of Counsel reasonably
satisfactory to the requesting party that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not be an expense
of the Depositor or the Trustee.  Neither the Depositor nor the Trustee is
obligated to register or qualify any Class E, Class F, Class G, Class A-X or
Class R Certificate under the Securities Act or any

                                      103
<PAGE>
 
other securities law or to take any action not otherwise required under this
Agreement to permit the transfer of such Certificate or interest without
registration or qualification.  Any such Holder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee and the Depositor against
any liability that may result if the transfer is not so exempt, or is not made
in accordance with federal and state laws.

          (f)  No transfer of a Class A-X, Class B, Class C, Class D, Class E,
Class F or Class G Certificate shall be made to any employee benefit or other
plan that is subject to the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), or Section 4975 of the Code (each, a "Plan"), or to any
trustee or any other person investing "plan assets" of any Plan, unless the
prospective transferee of a Certificateholder desiring to transfer its
Certificate provides the Trustee with a certification as set forth in paragraph
6 of Exhibit M or Opinion of Counsel, or both at the request of the Trustee,
     ---------                                                              
which establishes to the reasonable satisfaction of the Depositor and the
Trustee that either (i) such prospective transferee is not a Plan and is not
using "plan assets" of any Plan to purchase the Certificate or (ii) the purchase
and holding of a Certificate by, on behalf of or with "plan assets" of any Plan
will not constitute or result in a non-exempt prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code.  The Class R Certificates may
not be transferred to a Plan or to any trustee or other person investing "plan
assets" of any Plan.

          (g)  (i)  No Class R Certificate may be held or beneficially owned by
     a Disqualified Organization.  The Class R Certificates shall not be held or
     beneficially owned by a non-U.S. Person.  Prior to the registration of any
     transfer, sale, pledge or other disposition of a Class R Certificate, the
     proposed transferee shall provide to the Trustee a "transfer affidavit" in
     substantially the form set forth in Exhibit N, to the effect that such
                                         ---------                         
     transferee (1) agrees to be bound by the terms of this Agreement and any
     restrictions set forth on the face of such Class R Certificate, as the case
     may be and (2) is not a Disqualified Organization or a non-U.S. Person and
     will not hold such Class R Certificate on behalf of a Disqualified
     Organization or non-U.S. Person.  The transferor of the Class R Certificate
     shall also provide the Trustee with a Transferor Certificate substantially
     in the form of Exhibit O.
                    --------- 

               (ii)   In addition, any transfer, sale, pledge or other
     disposition of any such Certificate to a Pass-Through Entity shall not be
     registered unless the proposed transferee shall have agreed in writing, in
     such form as the Trustee may require, to provide to the Trustee such
     information as the Trustee may reasonably require concerning any record
     interest holder or principal of such Pass-Through Entity who is or was a
     Disqualified Organization. Any Holder of a Class R Certificate, by its
     acceptance thereof, shall be deemed for all purposes to have consented to
     the provisions of this Section 6.02(g).

               (iii)  The restrictions described in this Section 6.02(g) shall
     not apply to a transfer of any such Certificate if the Trustee has received
     an Opinion of Counsel to the effect that the restrictions described in this
     Section 6.02(g) are not necessary to avoid the imposition of tax on a REMIC
     or the disqualification of either REMIC as a REMIC under the Code.

                                      104
<PAGE>
 
          (h)  The Trustee shall have no liability to the Trust Fund arising
from a transfer of any such Certificate in reliance upon a certification, ruling
or Opinion of Counsel described in this Section 6.02; provided, however, that
                                                      --------  ------- 
the Trustee shall not register the transfer of a Class R Certificate if it has
actual knowledge that the proposed transferee does not meet the qualifications
of a permitted Holder of a Class R Certificate as set forth in this Section
6.02.

          SECTION 6.03.  MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.
                         ------------------------------------------------- 

          If (a) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and (b) except in the case of a mutilated Certificate so
surrendered, there is delivered to the Trustee such security or indemnity as may
be required by it to save it harmless, then, in the absence of notice to the
Trustee that such Certificate has been acquired by a bona fide purchaser, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
like tenor and interest in the Trust Fund.  In connection with the issuance of
any new Certificate under this Section 6.03, the Trustee 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) connected therewith.  Any replacement Certificate
issued pursuant to this Section 6.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time.

          SECTION 6.04.  PERSONS DEEMED OWNERS.
                         --------------------- 

          Prior to presentation of a Certificate for registration of transfer,
the Master Servicer, the Special Servicer, the Fiscal Agent, the Trustee, and
any agent of the Master Servicer, the Special Servicer, the Fiscal Agent or the
Trustee may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions as provided
in this Agreement and for all other purposes whatsoever, and neither the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, nor any agent of
the Master Servicer, the Special Servicer the Fiscal Agent, or the Trustee shall
be affected by any notice to the contrary.

          SECTION 6.05.  ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
                         -----------------------------------------------
                         ADDRESSES.
                         --------- 

          If three or more Certificateholders (a) request in writing from the
Trustee a list of the names and addresses of Certificateholders and (b) state
that such Certificateholders desire to communicate with other Certificateholders
with respect to their rights under this Agreement or under the Certificates,
then the Trustee shall, within ten Business Days after the receipt of such
request, afford such Certificateholders access during normal business hours to a
current list of the Certificateholders.  The expense of providing any such
information requested by a Certificateholder shall be borne by the
Certificateholders requesting such information and shall not be borne by the
Trustee.  Every Certificateholder, by receiving and holding a Certificate,
agrees that the Trustee shall not be held accountable

                                      105
<PAGE>
 
by reason of the disclosure of any such information as to the list of the
Certificateholders hereunder, regardless of the source from which such
information was derived.

          SECTION 6.06.  MAINTENANCE OF OFFICE OR AGENCY.
                         ------------------------------- 

          The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies in New York, New York where Certificates
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Trustee in respect of the Certificates and this
Agreement may be served. The Trustee initially designates IBJ Schroder Trust
Bank, Stock Transfer Department, One State Street Plaza, New York, New York
10015 for such purpose. The Trustee will give prompt written notice to the
Certificateholders of any change in the location of any such office or agency.

          SECTION 6.07.  BOOK-ENTRY CERTIFICATES.
                         ----------------------- 

     Notwithstanding the foregoing, the Publicly Offered Certificates, upon
original issuance, shall be issued in the form of one or more Certificates
representing the Book-Entry Certificates, to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Depositor. The Publicly Offered
Certificates shall initially be registered on the Certificate Register in the
name of Cede & Co., the nominee of DTC, as the initial Clearing Agency, and no
Beneficial Holder will receive a definitive certificate representing such
Beneficial Holder's interest in the Certificates, except as provided in Section
6.09. Unless and until definitive, fully registered Certificates ("Definitive
Certificates") have been issued to the Beneficial Holders pursuant to Section
6.09:

          (a)  the provisions of this Section 6.07 shall be in full force and
     effect with respect to the Offered Certificates;

          (b)  the Depositor and the Trustee may deal with the Clearing Agency
     for all purposes with respect to the Certificates (including the making of
     distributions on the Certificates) as the sole Offered Certificateholder;

          (c)  to the extent that the provisions of this Section 6.07 conflict
     with any other provisions of this Agreement, the provisions of this Section
     6.07 shall control; and

          (d)  the rights of the Beneficial Holders of the Publicly Offered
     Certificates shall be exercised only through the Clearing Agency and the
     Participants and shall be limited to those established by law and
     agreements between such Beneficial Holders and the Clearing Agency and/or
     the Participants.  Pursuant to the Depository Agreement, unless and until
     Publicly Offered Certificates are issued pursuant to Section 6.09, the
     initial Clearing Agency will make book-entry transfers among the
     Participants and receive and transmit distributions of principal and
     interest on the related Publicly Offered Certificates to such Participants.

                                      106
<PAGE>
 
          For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of, Holders of the
Publicly Offered Certificates evidencing a specified percentage of the aggregate
unpaid principal amount of Publicly Offered Certificates, such direction or
consent may be given by the Clearing Agency at the direction of Beneficial
Holders owning Publicly Offered Certificates evidencing the requisite percentage
of principal amount of Publicly Offered Certificates.  The Clearing Agency may
take conflicting actions with respect to the Offered Certificates to the extent
that such actions are taken on behalf of the Beneficial Holders.

          SECTION 6.08.  NOTICES TO CLEARING AGENCY.
                         -------------------------- 

          Whenever notice or other communication to the Publicly Offered
Certificateholders is required under this Agreement, unless and until Definitive
Certificates shall have been issued to the related Certificateholders pursuant
to Section 6.09, the Trustee shall give all such notices and communications
specified herein to be given to Holders of the Publicly Offered Certificates to
the Clearing Agency which shall give such notices and communications to the
related Participants in accordance with its applicable rules, regulations and
procedures.

          SECTION 6.09.  DEFINITIVE CERTIFICATES.
                         ----------------------- 

          If (a) the Depositor advises the Trustee in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
under the Depository Agreement with respect to the Certificates and the
Depositor is unable to locate a qualified successor, (b) the Depositor, at its
option, advises the Trustee in writing that it elects to terminate the book-
entry system with respect to the Publicly Offered Certificates through the
Clearing Agency or (c) after the occurrence of an Event of Default, Holders of
Publicly Offered Certificates evidencing not less than 66% of the aggregate
Certificate Principal Balance of the Publicly Offered Certificates advise the
Trustee in writing that the continuation of a book-entry system with respect to
the Publicly Offered Certificates through the Clearing Agency is no longer in
the best interests of the Publicly Offered Certificateholders with respect to
the Publicly Offered Certificates, the Trustee shall notify all Publicly Offered
Certificateholders of the occurrence of any such event and the availability of
Definitive Certificates.  Upon surrender to the Trustee of the Publicly Offered
Certificates by the Clearing Agency, accompanied by registration instructions
from the Clearing Agency for registration, the Trustee shall authenticate and
deliver the Definitive Certificates.  Neither the Depositor, the Fiscal Agent
nor the Trustee shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions.  Upon the issuance of Definitive Certificates all references
herein to obligations imposed upon or to be performed by the Clearing Agency
shall be deemed to be imposed upon and performed by the Trustee, to the extent
applicable with respect to such Definitive Certificates, and the Trustee shall
recognize the Holders of Definitive Certificates as Certificateholders
hereunder.

                         THE SPECIAL SERVICER.
                         -------------------- 

          The Depositor, the Master Servicer and the Special Servicer shall each
be liable, individually and not jointly, in accordance herewith only to the
extent of the obligations specifically and respectively imposed upon and
undertaken by them herein and shall not be liable to any Class or Classes of
Certificates for actions taken which may adversely affect the interests of such
Class or Classes of Certificates as compared to another Class or Classes of
Certificates, including in the circumstance in which the Master Servicer or the
Special Servicer owns an interest in the Certificates as described in Section
7.06.

          SECTION 7.02.  MERGER OR CONSOLIDATION OF THE DEPOSITOR, THE MASTER
                         ----------------------------------------------------
                         SERVICER OR THE SPECIAL SERVICER.
                         -------------------------------- 

          Each of the Depositor, the Master Servicer and the Special Servicer
will do or cause to be done all things necessary to preserve and keep in full
force and effect its existence, rights, good standing and will each obtain and
preserve its qualification to do business as a foreign corporation or limited
partnership, as applicable, in each jurisdiction in which such qualification is
or shall be necessary to protect the validity and enforceability of this
Agreement, or any of the Mortgage Loans and to perform its respective duties
under this Agreement.

          Any Person into which the Depositor, the Special Servicer or the
Master Servicer may be merged or consolidated, or any Person resulting from any
merger or consolidation to which the Depositor, the Special Servicer or the
Master Servicer shall be a party, or any Person succeeding to the business of
the Depositor, the Special Servicer or the Master Servicer, shall be the
successor of the Depositor, the Special Servicer or the Master Servicer, as the
case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that each of the Rating Agencies
                          --------  -------                                  
provides written acknowledgment that its rating of the Certificates in effect
immediately prior to such merger, consolidation, or succession will not be
qualified or reduced as a result of such merger, consolidation or succession.

          Notwithstanding anything else in this Section 7.02 or in Section 7.04
hereof to the contrary, in addition to the delegation of subservicing as
provided in Section 3.02, the Master Servicer and the Special Servicer may
assign their respective rights and delegate their respective duties and
obligations under this Agreement; provided, however, that the Master Servicer or
                                  --------  -------                             
the Special Servicer, as the case may be, gives the Depositor and the Trustee
notice of such assignment; and provided further, that such purchaser or
                               ----------------                        
transferee accepting such assignment and delegation shall be an institution
which is willing to service the Mortgage Loans and executes and delivers to the
Depositor and the Trustee an agreement accepting such delegation and assignment,
which contains an assumption by such Person of

                                      108
<PAGE>
 
the rights, powers, duties, responsibilities, obligations and liabilities of the
Master Servicer or the Special Servicer, as the case may be, with like effect as
if originally named as a party to this Agreement; and provided further, that

each of the Rating Agencies provides written acknowledgement that its rating of
the Certificates in effect immediately prior to such assignment and delegation
will not be qualified or reduced as a result of such assignment and delegation.
In the case of any such assignment and delegation in accordance with the
requirements of this Section 7.02, the Master Servicer or the Special Servicer,
as the case may be, shall be released from their respective 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 as Master Servicer or the Special Servicer, as the case may be, hereunder
prior to the satisfaction of the conditions to such assignment and delegation
set forth in the preceding sentence.

          SECTION 7.03.  LIMITATION ON LIABILITY OF THE DEPOSITOR, THE SPECIAL
                         -----------------------------------------------------
                         SERVICER, THE MASTER SERVICER, FISCAL AGENT AND OTHERS.
                         ------------------------------------------------------ 

          Neither the Depositor, the Special Servicer, the Master Servicer, the
Fiscal Agent nor any of the directors, officers, employees, shareholders,
attorneys, or agents of the Depositor, the Special Servicer, the Fiscal Agent or
the Master Servicer shall be under any liability to 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 Special Servicer, the Fiscal
Agent or the Master Servicer against any breach of representations or warranties
made by it herein or protect the Depositor, the Special Servicer, the Fiscal
Agent or the Master Servicer or any such Person from any liability which would
otherwise be imposed by reasons 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 Special Servicer, the Fiscal Agent or
the Master Servicer and any director, officer, employee, shareholders,
attorneys, or agent thereof 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, the Special Servicer, the Fiscal Agent or the
Master Servicer (and its general partner) and any director, officer, employee or
agent thereof shall be indemnified by the Trust Fund and held harmless against
any loss, liability or expense, including fees and disbursements of attorneys,
incurred in connection with any legal action or dispute relating to this
Agreement, any Mortgage Loans or any REO Property or the Certificates (including
any claims of violations of securities laws) or any exercise of any right under
this Agreement reasonably requiring the use of counsel or the incurring of
expenses, other than with respect to each such Person any loss, liability or
expense incurred by reason of its willful misfeasance, bad faith or negligence
in the performance of duties hereunder or by reason of its reckless disregard of
obligations and duties hereunder.  Neither the Depositor, the Special Servicer,
the Fiscal Agent nor the Master Servicer shall be under any obligation to appear
in, prosecute or defend any legal action that is not incidental to their
respective duties hereunder and which in its opinion may involve it in any
expense or liability; provided, however, that either the Depositor, the Special
                      --------  -------                                        
Servicer, the Fiscal Agent or the Master Servicer may in its discretion
undertake any such action related to its obligations hereunder that it may deem
necessary or desirable in respect of this Agreement and the rights and duties of
the parties

                                      109
<PAGE>
 
hereto and interests of the Trustee and the Certificateholders hereunder.  In
such event, the legal expenses and costs of such action and any liability
resulting therefrom shall be expenses, costs and liabilities of the Trust Fund,
and the Depositor, the Special Servicer, the Fiscal Agent and the Master
Servicer shall be entitled to be reimbursed therefor by the Trust Fund from
amounts in the Collection Account as provided by Section 3.12(f) hereof or
otherwise.  This indemnity shall survive the termination of this Agreement.

          In addition, the Master Servicer and the Special Servicer shall have
no liability with respect to, and shall be entitled to conclusively rely on as
to the truth of the statements and the correctness of the opinions expressed in
any certificates or opinions furnished to the Master Servicer or the Special
Servicer and conforming to the requirements of this Agreement.  Neither the
Master Servicer and/or the Special Servicer, nor any director, officer,
employee, agent or Affiliate, shall be personally liable for any error of
judgement made in good faith by any officer, unless it shall be proved that the
Master Servicer or the Special Servicer, as the case may be, or such officer was
negligent in ascertaining the pertinent facts.  Neither the Master Servicer or
the Special Servicer, nor any director, officer, employee, agent or affiliate,
shall be personally liable for any action taken, suffered or omitted by it in
good faith and believed by it to be authorized or within the discretion, rights
or powers conferred upon it by this Agreement.

          Neither the Master Servicer nor the Special Servicer shall be
obligated to incur any liabilities, costs, charges, fees or other expenses which
relate to or arise from any breach of any representation, warranty or covenant
made by the Depositor, the Fiscal Agent or Trustee in this Agreement.  The Trust
Fund shall indemnify and hold harmless the Master Servicer and the Special
Servicer from any and all claims, liabilities, costs, charges, fees or other
expenses which relate to or arise from any such breach of representation,
warranty or covenant.

          Except as otherwise specifically provided herein:

               (i)    the Master Servicer and the Special Servicer may rely, 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 believed by it to be genuine and to
have been signed or presented by the proper party or parties;

               (ii)   the Master Servicer and the Special Servicer may consult
with counsel, and any written advice or Opinion of Counsel shall be full and
complete authorization and protection with respect to any action taken or
suffered or omitted by it hereunder in good faith and in accordance with such
advice or Opinion of Counsel;

               (iii)  the Master Servicer and the Special Servicer shall not be
personally liable for any action taken, suffered or omitted by it in good faith
and believed by it to be authorized or within the discretion, rights or powers
conferred upon it by this Agreement; and

<PAGE>
 
               (iv)   the Master Servicer and the Special Servicer, in preparing
any reports hereunder, may rely, and shall be protected in acting or refraining
from acting upon any information (financial or other), statement, certificate,
document, agreement, covenant, notice, request or other paper reasonably
believed by it to be genuine and provided by any Mortgagor or manager of a
Mortgaged Property.

          The Master Servicer and the Special Servicer and any director,
officer, employee or agent of the Master Servicer and the Special Servicer shall
be indemnified by the Trustee and the Fiscal Agent, as the case may be, and held
harmless against any loss, liability or expense including reasonable attorneys'
fees incurred in connection with any legal action relating to the Trustee's or
the Fiscal Agent's, as the case may be, respective willful misfeasance, bad
faith or negligence in the performance of its respective duties hereunder or by
reason of reckless disregard of its respective duties hereunder, other than any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence in the performance of any of the Master Servicer's and the Special
Servicer's duties hereunder or by reason of reckless disregard of the Master
Servicer's or Special Servicer's obligations and duties hereunder.  Such
indemnity shall survive the termination of this Agreement or the resignation or
removal of the Master Servicer or the Special Servicer hereunder.  Any payment
hereunder made by the Trustee or the Fiscal Agent pursuant to this paragraph to
the Master Servicer and the Special Servicer shall be paid from the Trustee's or
Fiscal Agent's own funds, without reimbursement from the Trust Fund therefor
except achieved through subrogation as provided in this Agreement.

          SECTION 7.04.  MASTER SERVICER NOT TO RESIGN.
                         ----------------------------- 

          The Master Servicer shall not resign from the obligations and duties
imposed upon it hereunder except upon determination that such obligations and
duties hereunder are no longer permissible under applicable law.  Any such
determination permitting the resignation of the Master Servicer under this
Section 7.04 shall be evidenced by an Opinion of Counsel to such effect
delivered to the Trustee, which shall not be an expense of the Trust Fund.  The
Master Servicer shall give notice of any proposed resignation to the Trustee,
the Special Servicer, the Certificateholders and the Rating Agencies.  No such
resignation by the Master Servicer shall become effective until the Trustee or a
successor servicer shall have assumed the Master Servicer's responsibilities and
obligations in accordance with Section 8.02 hereof.

          SECTION 7.05.  ERRORS AND OMISSIONS INSURANCE; FIDELITY BONDS.
                         ---------------------------------------------- 

          The Master Servicer and the Special Servicer shall, for so long as
each acts as a servicer under this Agreement, obtain and maintain in force (a) a
policy or policies of insurance covering errors and omissions in the performance
of its obligations as a servicer hereunder, and (b) a fidelity bond in respect
of its officers, employees and agents (to the extent such agents are under the
supervision, direction and control of the Master Servicer or the Special
Servicer, as applicable).  Each such policy or policies and bond shall be issued
by a Qualified Insurer and be in form and amount consistent with the Servicing
Standard.  In the event that any such policy or bond ceases to be in effect, the
Master Servicer or the Special Servicer, as the case may be, shall obtain a
comparable replacement policy or bond

                                      111
<PAGE>
 
from an insurer or issuer, meeting the requirements set forth above as of the
date of such replacement.  So long as the long-term rating of the Master
Servicer or Special Servicer, as the case may be, is not less than two rating
categories (ignoring pluses or minuses) lower than the highest rating of any
Class of Certificates as rated by S&P and D&P (if rated by D&P), but in any
event not less than "BBB" or "BBBq" (or its equivalent rating) by D&P (if rated
by D&P) or S&P, respectively, the Master Servicer or the Special Servicer, as
the case may be, may self-insure for the coverage required in (a) and (b) above.

          SECTION 7.06.  MASTER SERVICER AND SPECIAL SERVICER MAY OWN
                         --------------------------------------------
                         CERTIFICATES.
                         ------------ 

          The Master Servicer (if it is not Wells Fargo Bank, National
Association unless it acquires the Certificates at the then fair market value of
such Certificates) and the Special Servicer may become the owner or pledgee of
Certificates with the same rights as they would have if they were not the Master
Servicer or the Special Servicer, as the case may be.  Any such interest of the
Master Servicer or the Special Servicer in the Certificates shall not be taken
into account when evaluating whether actions of the Master Servicer or the
Special Servicer are consistent with their respective obligations in accordance
with the loan Servicing Standard and procedures set forth in Section 3.01
hereto, regardless of whether such actions may have the effect of benefitting
the Class or Classes of Certificates owned by the Master Servicer or Special
Servicer.

                                    DEFAULT

          SECTION 8.01.  EVENTS OF DEFAULT.
                         ----------------- 

          "Event of Default", wherever used herein, means any one of the
following events:

               (a)  any failure (i) by the Master Servicer to remit to the
     Trustee any payment required to be remitted by the Master Servicer under
     the terms of this Agreement (provided that it shall not be an event of
     default if the Master Servicer fails to remit an amount to the Trustee due
     solely to the failure of the Special Servicer to remit to the Master
     Servicer any amount required to be remitted to it pursuant to this
     Agreement) or (ii) by the Special Servicer to remit to the Master Servicer
     or the Trustee any payment required to be remitted by the Special Servicer
     under the terms of this Agreement; or

               (b)  any failure by the Master Servicer or the Special Servicer
     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, as
     the case may be, contained in this Agreement (except as set forth in (c)
     below) which failure (i) materially affects the rights of the
     Certificateholders and (ii) shall continue unremedied for a period of 90
     days (except that such number of days shall be 20 in

                                      112
<PAGE>
 
     the case of a failure to pay the premium for any Required Insurance Policy)
     after the date on which written notice of such failure 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, and the Trustee by the Holders of
     Certificates evidencing not less than 25% of the aggregate then outstanding
     Voting Rights of the Certificates; or

               (c)  if a representation or warranty set forth in Section 2.04
     hereof shall prove to be incorrect as of the time made in any respect that
     materially and adversely affects the interests of the Certificateholders,
     and the circumstances or condition in respect of which such representation
     or warranty was incorrect shall not have been eliminated or cured within
     120 days of the discovery or receipt of notice thereof; or

               (d)  a decree or order of a court or agency or supervisory
     authority having jurisdiction in the premises for the appointment of a
     conservator or receiver or liquidator in any 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

               (e)  the Master Servicer or the Special Servicer shall consent to
     the appointment of a conservator or receiver or liquidator in any
     insolvency, readjustment of debt, marshalling of assets and liabilities or
     similar proceedings of or relating to the Master Servicer or the Special
     Servicer, as the case may be, or all or substantially all of the property
     of the Master Servicer or the Special Servicer, as the case may be; or

               (f)  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, or commence a voluntary case under, any
     applicable insolvency or reorganization statute, make an assignment for the
     benefit of its creditors, or voluntarily suspend payment of its
     obligations; or

               (g)  either Rating Agency shall lower or withdraw the outstanding
     rating of the Certificates because the existing or prospective financial
     condition or mortgage loan servicing capability of the Master Servicer or
     the Special Servicer is insufficient to maintain such outstanding rating.

          If an Event of Default due to the actions or inaction of the Master
Servicer or the Special Servicer, as the case may be, shall occur, then, and in
each and every such case, so long as such Event of Default shall not have been
remedied, the Trustee may, and if so directed by the Holders of Certificates
evidencing not less than 25% of all the Voting Rights evidenced by all
outstanding Certificates, shall, by notice in writing to the Master Servicer or
the Special Servicer, as the case may be, (with a copy to the Rating Agencies),
terminate all of the rights and obligations of the Master Servicer or the
Special Servicer, as the case may

                                      113
<PAGE>
 
be, under this Agreement (other than rights to reimbursement for Advances
previously made, with interest thereon at the Advance Rate, as provided in
Section 3.12 and accrued indemnities, fees and reimbursement rights).

          In addition to the right of the Trustee to terminate the rights and
obligations of the Master Servicer or the Special Servicer hereunder as a result
of an Event of Default, the Trustee shall have all other rights and remedies
available at law or in equity against the Master Servicer or the Special
Servicer as a result of such Event of Default.

          SECTION 8.02.  TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.
                         ---------------------------------------- 

          On and after the time the Master Servicer or the Special Servicer, as
the case may be, receives a notice of termination pursuant to Section 8.01
hereof or resigns pursuant to Section 7.04 hereof, subject to the provisions of
Section 3.07 hereof, 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
servicer under this Agreement and with respect to the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer or the Special
Servicer, as the case may be, by the terms and provisions hereof, subject to
Section 3.07, provided that the Trustee shall not (i) be deemed to have made any
representation or warranty as to any Mortgage Loan made by the Master Servicer
or the Special Servicer, (ii) be responsible for any liabilities incurred by the
Master Servicer or the Special Servicer prior to an Event of Default, and (iii)
shall not be liable to effect any repurchases or substitutions of any Mortgage
Loan.  As compensation therefor, the Trustee shall be entitled to all fees
relating to the Mortgage Loans that the Master Servicer or the Special Servicer,
as the case may be, would have been entitled to charge to the related Collection
Account if the Master Servicer or the Special Servicer, as the case may be, had
continued to act hereunder.  Notwithstanding the foregoing, if the Trustee has
become the successor to the Master Servicer or the Special Servicer in
accordance with this Section 8.02, the Trustee may, if it shall be unwilling to
so act, or shall, if it is unable to so act (exclusive of the obligations with
respect to Monthly Advances), appoint, or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution,
the appointment of which does not adversely affect the then current rating of
the Certificates (as evidenced in writing by the applicable Rating Agencies), as
the successor to the Master Servicer or the Special Servicer, as the case may
be, hereunder 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.  Pending appointment of a successor to the Master Servicer or the
Special Servicer hereunder, the Trustee, unless prohibited by law from so
acting, shall act in such capacity as provided herein.  In connection with such
appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; provided, however, that no such compensation shall be in
                       --------  -------                                       
excess of that permitted the Master Servicer or the Special Servicer, as the
case may be, hereunder.  The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession.  Neither the Trustee nor any other successor servicer shall be
deemed to be in default hereunder by reason of any failure to make, or any delay
in making, any distribution hereunder or any portion thereof

                                      114
<PAGE>
 
caused by the failure of the Master Servicer or the Special Servicer, as the
case may be, to deliver, or any delay in delivering, cash, documents or records
to it.

          Any successor to the Master Servicer or the Special Servicer shall,
during the term of its service as servicer, maintain in force the policy or
policies that the Master Servicer or the Special Servicer, as the case may be,
is required to maintain pursuant to Section 7.05 hereof.

          SECTION 8.03.  NOTIFICATION TO CERTIFICATEHOLDERS.
                         ---------------------------------- 

          (a)  Upon any termination or appointment of a successor to the Master
Servicer or the Special Servicer, as the case may be, the Trustee shall give
prompt written notice thereof to Certificateholders and to the Rating Agencies.

          (b)  Within 10 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Certificateholders and the Rating Agencies
notice of each such Event of Default hereunder known to the Trustee, unless such
Event of Default shall have been cured or waived.


                                  ARTICLE IX

                            CONCERNING THE TRUSTEE

          SECTION 9.01.  DUTIES OF TRUSTEE.
                         ----------------- 

          The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default that may have occurred, undertakes with
respect to the Trust Fund to perform such duties and only such duties as are
specifically set forth in this Agreement.  In case an Event of Default has
occurred and remains uncured, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement, and use the same degree of care and skill
in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.  Any permissive right
of the Trustee set forth in this Agreement shall not be construed as a duty.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they conform
to the requirements of this Agreement.  The Trustee shall have no duty to
recompute, recalculate or verify the accuracy of any resolution, certificate,
statement, opinion, report, document, order or other instrument so furnished to
the Trustee.

          No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct, its negligent failure to perform its obligations
in compliance with this Agreement, or any liability which would be imposed by
reason of its willful misfeasance or bad faith; provided, however, that:
                                                --------  -------       

                                      115
<PAGE>
 
               (a)  prior to the occurrence of an Event of Default, and after
     the curing of all such Events of Default that may have occurred, the duties
     and obligations of the Trustee shall be determined solely by the express
     provisions of this Agreement, the Trustee shall not be personally 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 and the
     Trustee 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 and conforming to the requirements of
     this Agreement which it reasonably believed in good faith to be genuine and
     to have been duly executed by the proper authorities respecting any matters
     arising hereunder;

               (b)  the Trustee shall not be personally liable for an error of
     judgment made in good faith by a Responsible Officer or Responsible
     Officers of the Trustee, unless the Trustee was negligent or acted in bad
     faith or with willful misfeasance;

               (c)  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 evidencing not
     less than 25% of the aggregate Certificate Principal Balance of each Class
     of Certificates 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; and

               (d)  no provision of this Agreement shall require the Trustee or
     the Fiscal Agent 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.

          Except with respect to an Event of Default described in clause (a) or
(h) of Section 8.01, the Trustee shall not be deemed to have knowledge of any
Event of Default or event which, with notice or lapse of time, or both, would
become an Event of Default, unless a Responsible Officer of the Trustee shall
have received written notice thereof from the Master Servicer, the Special
Servicer, the Depositor or a Certificateholder, or a Responsible Officer of the
Trustee has actual notice thereof, provided that the Trustee shall nonetheless
be deemed to have knowledge of a default resulting from the failure to provide
scheduled reports, certificates and statements called for in this Agreement, and
in the absence of such notice no provision hereof requiring the taking of any
action or the assumption of any duties or responsibility by the Trustee
following the occurrence of any Event of Default or event which, with notice or
lapse of time or both, would become an Event of Default, shall be effective as
to the Trustee.

          SECTION 9.02.  CERTAIN MATTERS AFFECTING THE TRUSTEE.
                         ------------------------------------- 

          (a)  Except as otherwise provided in Section 9.01:

               (i)    the Trustee may request and rely upon and shall be
          protected in acting or refraining from acting upon any resolution,
          Officers' Certificate, certificate of auditors or any other
          certificate, statement, instrument, opinion, report, notice, request,

          respect of any action taken or suffered or omitted by it hereunder in
          good faith and in accordance with such Opinion of Counsel;

               (iii)  the Trustee shall be under no obligation to exercise any
          of the trusts or powers vested in it by this Agreement or to
          institute, conduct or defend any litigation hereunder or in relation
          hereto at the request, order or direction of any of the
          Certificateholders, pursuant to the provisions of this Agreement,
          unless such Certificateholders shall have offered to the Trustee
          reasonable security or indemnity against the costs, expenses and
          liabilities which may be incurred therein or thereby; provided,

          not been cured or waived), to exercise such of the rights and powers
          vested in it by this Agreement, and to use the same degree of care and
          skill in their exercise as a prudent person would exercise or use
          under the circumstances in the conduct of such person's own affairs;

               (iv)   the Trustee shall not be personally liable for any action

          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
          so to do by Holders of Certificates evidencing not less than 25% of
          the aggregate Voting Rights of each Class of Certificates; provided,
                                                                     --------

          -------
          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; the reasonable expense of every such

                                      117
<PAGE>
 
          investigation shall be paid by the Master Servicer in the event that
          such investigation relates to an Event of Default by the Master
          Servicer, if an Event of Default by the Master Servicer shall have
          occurred and is continuing, and otherwise by the Certificateholders
          requesting the investigation; the reasonable expense of every such
          investigation shall be paid by the Special Servicer in the event that
          such investigation relates to an Event of Default by the Special
          Servicer, if an Event of Default by the Special Servicer shall have

          or otherwise incur any financial liability in the performance of any
          of its duties hereunder if it shall have reasonable grounds for
          believing that repayment of such funds or adequate indemnity against
          such liability is not assured to it; and

               (viii) the Trustee shall not be liable for any loss on any
          investment of funds pursuant to this Agreement.

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

          SECTION 9.03.  TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.
                         ----------------------------------------------------- 

          The recitals contained herein shall be taken as the statements of the
Depositor, and the Trustee and the Fiscal Agent assume no responsibility for
their correctness.  The Trustee and the Fiscal Agent make no representations as
to the validity or sufficiency of this Agreement, the Certificates or of any
Mortgage Loan or related document.  The Trustee and the Fiscal Agent shall not
be accountable for the use or application by the Depositor, the Special Servicer
or the Master Servicer of any funds paid to the Depositor, the Special Servicer
or the Master Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Master Servicer, the Depositor or
the Special Servicer.

          SECTION 9.04.  TRUSTEE MAY OWN CERTIFICATES.
                         ---------------------------- 

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Certificates with the same rights as it would have if it
were not the Trustee.

          SECTION 9.05.  MASTER SERVICER TO PAY TRUSTEE'S FEES AND EXPENSES.
                         -------------------------------------------------- 

          The Master Servicer shall pay from its own funds on each Distribution
Date the Trustee Fee to the Trustee. In addition, to the extent not recoverable
from other sources or credits available to the Trustee, the Master Servicer will
pay or reimburse the Trustee upon its request from amounts on deposit in the
Collection Account for all expenses and disbursements incurred or made by the
Trustee and the Fiscal Agent beyond usual and customary expenses to the extent
necessary for the performance of the Trustee and the Fiscal Agent in accordance
with any of the provisions of this Agreement (including indemnification for any
loss or liability incurred by it in any legal proceeding brought against it and
including the reasonable compensation, expenses and disbursements of its counsel
and of all other persons not regularly in its employ, whether or not such
expenses are incurred in connection with any Opinion of Counsel required or
permitted to be obtained by the Trustee and the Fiscal Agent), except any such
loss, liability, expense or disbursement as may arise from the Trustee's or the
Fiscal Agent's negligence, bad faith or willful misconduct. The amounts so
payable or reimbursable to the Trustee shall be Additional Trust Fund Expenses.
In the event that the Master Servicer fails to pay or reimburse the Trustee or
the Fiscal Agent to the extent required by the preceding sentence, the Trustee
shall be reimbursed from the Trust Fund therefor pursuant to Section 3.12
hereof. As used herein "beyond usual and customary expenses" of the Trustee or
the Fiscal Agent are those which, necessary under this Agreement, are not of a
type or character for which trustees in comparable situations could generally
expect reimbursement from the assets in the trust fund.

          The Trustee and the Fiscal Agent and any director, officer, employee
or agent of the Trustee and the Fiscal Agent shall be indemnified by the Master
Servicer and the Special Servicer, as the case may be, and held harmless against
any loss, liability or expense including reasonable attorneys' fees incurred in
connection with any legal action relating to the Master Servicer's or the
Special Servicer's, as the case may be, respective willful misfeasance, bad
faith or negligence in the performance of its respective duties hereunder or by
reason of reckless disregard of its respective duties hereunder, other than any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence in the performance of any of the Trustee's and the Fiscal Agent's
duties hereunder or by reason of reckless disregard of the Trustee's obligations
and duties hereunder. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Trustee or the Fiscal Agent
hereunder. Any payment hereunder made by the Master Servicer or the Special
Servicer pursuant to this paragraph to the Trustee and the Fiscal Agent shall be
paid from the Master Servicer's or Special Servicer's own funds, without
reimbursement from the Trust Fund therefor except achieved through subrogation
as provided in this Agreement.

          SECTION 9.06.  ELIGIBILITY REQUIREMENTS FOR TRUSTEE.
                         ------------------------------------ 

          The Trustee hereunder shall at all times be a corporation or
association having its principal office in a state and city acceptable to the
Depositor and organized and doing business under the laws of such state or the
United States of America, authorized under such laws to exercise corporate trust
powers, having a rating on its long-term debt obligations at the time of such
appointment in the second highest rating category by the Rating Agencies or such
lower rating as is acceptable to the Rating Agencies in writing as will not
cause the

                                      119
<PAGE>
 
Rating Agencies to lower its then-current ratings of the Certificates, having a
combined capital and surplus of at least $50,000,000 and subject to supervision
or examination by federal or state authority.  If such corporation or
association 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 9.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 9.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.07 hereof.  Notwithstanding
the above, any successor Trustee need not meet such rating requirements so long
as there is a Fiscal Agent which satisfies such rating requirements.

          SECTION 9.07.  RESIGNATION AND REMOVAL OF TRUSTEE.
                         ---------------------------------- 

          The Trustee, and correspondingly the Fiscal Agent, may at any time
resign and be discharged from the trusts hereby created by (a) giving written
notice of resignation to the Depositor and by mailing notice of resignation by
first class mail, postage prepaid, to the Certificateholders at their addresses
appearing on the Certificate Register, and to the Rating Agencies, not less than
60 days before the date specified in such notice when, subject to Section 9.08,
such resignation is to take effect, and (b) acceptance by a successor trustee
and if required a successor fiscal agent in accordance with Section 9.08 meeting
the qualifications set forth in Section 9.06. If no successor trustee shall have
been so appointed and have accepted appointment within 30 days after the giving
of such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee.

          If (i) at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.06 hereof and shall fail to resign
after written request thereto by the Depositor, or (ii) at any time the Trustee
shall become incapable of acting, or shall be adjudged a bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or (iii)
at any time, the Trustee and the Fiscal Agent fail to make any remittance
required hereunder to the Certificateholders or fail to make any Advance
required hereunder then the Depositor may remove the Trustee and Fiscal Agent
and appoint a successor trustee and successor fiscal agent, if required, by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the Trustee and one copy to the successor trustee. The Trustee and
Fiscal Agent may also be removed at any time by the Holders of Certificates
evidencing not less than 50% of the aggregate Voting Rights of all outstanding
Certificates. Notice of any removal of the Trustee or Fiscal Agent and
acceptance of appointment by the successor trustee shall be given to the Rating
Agencies.

          Any resignation or removal of the Trustee or Fiscal Agent and
appointment of a successor trustee or successor fiscal agent, if required,
pursuant to any of the provisions of this Section 9.07 shall become effective
upon acceptance of appointment by the successor trustee or successor fiscal
agent, if required, as provided in Section 9.08 hereof. Upon such resignation or
removal of the initial Trustee, the obligations of the Fiscal Agent shall be

                                      120
<PAGE>
 
assumed by the successor trustee and the Fiscal Agent shall automatically be
released from any obligation under this Agreement.  A successor fiscal agent
shall be required to be obtained only if the Trustee fails to satisfy the rating
requirements of Section 9.06.

          SECTION 9.08.  SUCCESSOR TRUSTEE AND FISCAL AGENT.
                         ---------------------------------- 

          Any successor trustee and any successor fiscal agent appointed as
provided in Section 9.07 hereof shall execute, acknowledge and deliver to the
Depositor and to its predecessor trustee and predecessor fiscal agent an
instrument accepting such appointment hereunder and thereupon the resignation or
removal of the predecessor trustee and predecessor fiscal agent shall become
effective and such successor trustee, 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 herein. The Depositor and the predecessor trustee and
predecessor fiscal agent, upon payment to it of all amounts to which it is
entitled hereunder, shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor trustee all such rights, powers, duties, and
obligations.

          No successor trustee or successor fiscal agent shall accept
appointment as provided in this Section 9.08 unless at the time of such
acceptance such successor trustee and a successor fiscal agent shall be eligible
under the provisions of Section 9.06 hereof and its appointment shall not
adversely affect the then current rating of the Certificates as confirmed in
writing by the Rating Agencies.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 9.08, the successor trustee shall mail notice of the succession of
such trustee and fiscal agent hereunder to all Holders of Certificates at their
addresses as shown in the Certificate Register and to each Rating Agency.

          SECTION 9.09.  MERGER OR CONSOLIDATION OF TRUSTEE OR FISCAL AGENT.
                         -------------------------------------------------- 

          Any Person into which the Trustee may be merged or converted or with
which it may be consolidated or any Person resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any Person succeeding
to the business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such Person shall be eligible under the provisions of Section 9.06
hereof, without the execution or filing of any paper or further act on the part
of any of the parties hereto, anything herein to the contrary notwithstanding,
if written confirmation shall have been received from each applicable Rating
Agency that such merger or consolidation would not result in the withdrawal or
downgrading of the then current ratings assigned to any Class of Certificates by
each applicable Rating Agency.

                                      121

          Any Person into which the Fiscal Agent may be merged or converted or
with which it may be consolidated or any Person resulting from any merger,
conversion or consolidation to which the Fiscal Agent shall be a party, or any
Person succeeding to the business of the Fiscal Agent, shall be the successor of
the Fiscal Agent hereunder, without the execution or filing of any paper or
further act on the part of any of the parties hereto, provided that such Person
shall be eligible under the provisions of Section 9.06 hereof, anything herein
to the contrary notwithstanding, if written confirmation shall have been
received from each applicable Rating Agency that such merger or consolidation
would not result in the withdrawal or downgrading of the then current ratings
assigned to any Class of Certificates by each applicable Rating Agency.

          SECTION 9.10.  APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
                         --------------------------------------------- 

          Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust Fund or Mortgaged Property securing any Mortgage Note may
at the time be located, the Special 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 and for the benefit of the applicable Certificateholders, such title to
the Trust Fund, or any part thereof, and, subject to the other provisions of
this Section 9.10, such powers, duties, obligations, rights and trusts as the
Special Servicer and the Trustee may consider necessary or desirable. If the
Special Servicer shall not have joined in such appointment within fifteen days
after the receipt by it of a request to do so, or in the case an Event of
Default 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 9.06 and no notice to Certificateholders of the appointment of any co-
trustee or separate trustee shall be required under Section 9.08.

          Every separate trustee and co-trustee shall, to the extent permitted
by law, be appointed and act subject to the following provisions and conditions:

               (a)  all rights, powers, duties and obligations conferred or
     imposed upon the Trustee, except for any obligation of the Trustee under
     this Agreement to advance funds on behalf of the Master Servicer, shall be
     conferred or imposed upon and exercised or performed by the Trustee and
     such separate trustee or co-trustee jointly (it being understood that such
     separate trustee or co-trustee is not authorized to act separately without
     the Trustee joining in such act), except to the extent that under any law
     of any jurisdiction in which any particular act or acts are to be performed
     by the Trustee (whether as Trustee hereunder or as successor to the Master
     Servicer or the Special Servicer, as the case may be), 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 singly by such separate trustee or co-trustee, but
     solely at the direction of the Trustee;

                                      122
<PAGE>
 
               (b)  no trustee hereunder shall be held personally liable by
     reason of any act or omission of any other trustee hereunder; and

               (c)  the Special Servicer and the Trustee acting jointly may at
     any time accept the resignation of or remove any separate trustee or co-
     trustee.

          Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. 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 and a copy thereof given to the
Master Servicer, the Special Servicer and the Depositor.

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

willful misfeasance; provided, however, that (i) the duties and obligations of
                     --------  -------

Sections 5.01 and 5.02, the Fiscal Agent shall not be liable except for the
performance of such duties and obligations, no implied covenants or obligations
shall be read into this Agreement against the Fiscal Agent and, in the absence
of bad faith on the part of the Fiscal Agent, the Fiscal Agent may conclusively
rely, as to the truth and correctness of the statements or conclusions expressed
therein, upon any resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to the Fiscal Agent by the
Depositor, the Servicer or the Trustee and which on their face do not contradict
the requirements of this Agreement, and (ii) the provisions of clause (b) of
Section 9.01 shall apply to the Fiscal Agent.

          (d)  Except as otherwise provided in this Section 9.13(c), the Fiscal

equal to the greater of (A) the sum of (1) the aggregate outstanding principal
balance of the Mortgage Loans (other than Liquidated Loans and Mortgage Loans as
to which a Final Recovery Determination has been made) as of the date of
purchase, together with accrued and unpaid interest thereon from the date to
which such interest was paid or advanced at the sum of the applicable Mortgage
Interest Rate (or the Net Mortgage Interest Rate, in the case of a purchase by
the Master Servicer) with respect to each such Mortgage Loan through the last
day of the month of such purchase, plus (2) the appraised value of any property
acquired in respect of the Mortgage Loans (as determined by an independent MAI
certified appraiser retained by the Trustee at the expense of the Trust Fund
within 3 months of such purchase) and (B) the fair price or market value of the
Mortgage Loans and any remaining property in the Trust Fund related thereto (as
determined by an independent MAI certified appraiser retained by the Trustee at
the expense of the Trust Fund within 3 months of such purchase). The Master
Servicer or the Special Servicer, as the case may be, shall give notice to the
Rating Agencies of the Master Servicer's or the Special Servicer's election to
purchase the Mortgage Loans pursuant to Section 10.01(a) and, where applicable,
of the Optional Termination Date.

          SECTION 10.02. TERMINATION OF TIER 2 REMIC.
                         --------------------------- 

          Tier 2 REMIC shall be terminated on the earlier of (a) the last Final
Rated Distribution Date for the Regular Certificates and (b) the date on which
the Tier 2 REMIC is deemed to receive the last deemed distributions on the
Uncertificated Tier 1 REMIC Regular Interests and the last distribution on the
Class R-II Certificate is made.

          SECTION 10.03. PROCEDURE UPON OPTIONAL PURCHASE.
                         -------------------------------- 

          (a)  In case of any Optional Purchase pursuant to Section 10.01(a),
the Person exercising such purchase option shall, at least twenty days prior to
the date notice is to be mailed to the affected Certificateholders notify the
Trustee and the other parties hereto of such Optional Purchase, the applicable
Distribution Date on which the purchase will be made, whether such date will be
the Optional Termination Date, and the applicable Mortgage Loan Purchase Price
of the related Mortgage Loans to be purchased.

                                      125
<PAGE>
 
          (b)  Any purchase of the Mortgage Loans shall be made by deposit of
the applicable Mortgage Loan Purchase Price into the Distribution Account, as
applicable, on or before the Distribution Date on which such purchase is
effected. Upon receipt by the Trustee of an Officer's Certificate of the Master
Servicer certifying as to the deposit of such Mortgage Loan Purchase Price into
the Distribution Account, the Trustee shall, upon request and at the expense of
the Master Servicer or the Special Servicer, as the case may be, execute and
deliver all such instruments of transfer or assignment, in each case without
recourse, as shall be reasonably requested by the Master Servicer or the Special
Servicer as the case may be, to vest title in the Master Servicer or the Special
Servicer, as the case may be, in the related Mortgage Loans so purchased and
shall transfer or deliver to the Master Servicer or the Special Servicer, as the
case may be, the purchased Mortgage Loans. Any distributions on the Mortgage
Loans received by the Trustee subsequent to (or with respect to any period
subsequent to) the date as of which the Mortgage Loans are so purchased shall be
promptly remitted by it to the Master Servicer or the Special Servicer, as the
case may be.

          (c)  Notice of the Distribution Date on which the Master Servicer
anticipates that the final distribution shall be made (whether upon Optional
Purchase or otherwise), shall be given promptly by the Master Servicer to the
Trustee and by the Trustee by first class mail to Holders of the affected
Certificates and each Rating Agency.  To the extent reasonably possible, such
notice shall be mailed no earlier than the 15th day and not later than the 10th
day preceding the Optional Termination Date or date of final distribution, as
the case may be.  Such notice shall specify (i) the Distribution Date upon which
final distribution on the affected Certificates will be made, (ii) the amount of
such final distribution, (iii) that the Record Date otherwise applicable to such
Distribution Date is not applicable, and (iv) that such distribution will be
made only upon presentation and surrender of such Certificates at the office or
agency maintained for such purposes (the address of which shall be set forth in
such notice). No notice of an Optional Purchase need be given to Holders unless
such Optional Purchase results in a termination of this Agreement.

          (d)  Upon presentation and surrender of the applicable Certificates,
the Trustee shall cause to be distributed to the Certificateholders on the final
Distribution Date the final distributions with respect thereto. Upon any such
termination, the Trustee shall terminate, or request the appropriate party to
terminate, the Collection Account, the Distribution Account and any other
account or fund maintained insofar as it related to the respective Certificates,
subject to the Trustee's obligation hereunder to hold all amounts payable to the
Certificateholders in trust without interest pending such payment.

          (e)  In the event that any Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to any such Certificateholders to surrender their Certificates for cancellation
and receive the final distribution with respect thereto.  If within six months
after the second notice all the Certificates shall not have been surrendered for
cancellation, the Trustee may take appropriate steps, or may appoint an agent to
take appropriate steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of the
funds and other assets which remain subject to the Trust Fund.

          SECTION 10.04. ADDITIONAL TERMINATION REQUIREMENTS.
                         ----------------------------------- 

          (a)  In the event the Master Servicer or the Special Servicer
exercises its purchase option pursuant to Section 10.01(a), the Tier 1 REMIC or
the Tier 2 REMIC, as applicable, shall be terminated in accordance with the
following additional requirements, unless the Trustee has received an Opinion of
Counsel (which Opinion of Counsel shall be acquired by and at the expense of the
party exercising the purchase option) to the effect that the failure of the Tier
1 REMIC or Tier 2 REMIC, as applicable, to comply with the requirements of this
Section 10.04 will not (i) result in the imposition of taxes on a "prohibited
transaction" of the Tier 1 REMIC or Tier 2 REMIC, as applicable, as described in
Section 860F of the Code, or (ii) cause either of the REMICs to fail to qualify
as a REMIC at any time that any Certificates are outstanding:

               (A)  within 90 days prior to the Optional Termination Date or the
          final Distribution Date, as applicable, set forth in the notice given
          by the Master Servicer under Section 10.03, the Trustee shall adopt a
          plan of complete liquidation of the related Tier 1 REMIC and Tier 2
          REMIC (meeting the requirements of a qualified liquidation under the
          REMIC Provisions) and the Trustee shall designate such dates as the
          date of adoption of a plan of complete liquidation in each REMIC's
          final federal income tax return; and

               (B)  at or after the time of adoption of any such plan of
          complete liquidation for the applicable Tier 1 REMIC and Tier 2 REMIC,
          at or prior to the final Distribution Date, the Trustee shall sell all
          of the assets of the Trust Fund for cash.

          (b)  The Trustee, and by its acceptance of a Class R-II Certificate,
the Holder thereof, shall be deemed to have agreed to adopt such a plan of
complete liquidation and to take such other action in connection therewith as
may be reasonably required to liquidate and otherwise terminate the Trust Fund.

          (a)  It is the express intent of the parties hereto that the
conveyance of the Trust Fund to the Trustee by the Depositor as provided in
Section 2.01 be, and be construed as, an absolute sale of the Trust Fund. It is,
further, not the intention of the parties that such conveyance be deemed a
pledge of the Trust Fund by the Depositor to the Trustee to secure a debt or
other obligation of the Depositor. However, in the event that, notwithstanding
the intent of the parties, the Trust Fund is held to be the property of the
Depositor, or if for any other reason this Agreement is held or deemed to create
a security interest in the Trust Fund, then

                                      129
<PAGE>
 
          (1)  this Agreement shall be deemed to be a security agreement; and

          (2)  the conveyance provided for in Section 2.01 shall be deemed to be
     a grant by the Depositor to the Trustee of a security interest in all of

          paper, instruments, documents, money, deposit accounts, certificates

          any of the property described in (x) and (y) below: (x) the Mortgage
          Loans including the Mortgage Notes, related Mortgages, related
          Assignments of Rents, and title, hazard and primary mortgage insurance
          policies identified on the Mortgage Loan Schedule as defined herein,

          on liquidation of any investment purchased at a discount); and (z) the
          Mortgage Loan Purchase Agreement;

               (II)  All accounts, contract rights, general intangibles, chattel

conveyance of the Uncertificated Tier I REMIC Regular Interests to the Trustee
by the Depositor as provided in Section 2.01 be, and be construed as, an
absolute sale of the Uncertificated Tier I REMIC Regular Interests. It is,
further, not the intention of the parties that such conveyance be deemed a
pledge of the Uncertificated Tier I REMIC Regular Interests by the Depositor to
the Trustee to secure a debt or other obligation of the Depositor.  However, in
the event that, notwithstanding the intent of the parties, the Uncertificated
Tier I REMIC Regular Interests are held to be the property of the Depositor, or
if for any other reason this Agreement is held or deemed to create a security
interest in the Uncertificated Tier I REMIC Regular Interests, then

               (1)  this Agreement shall be deemed to be a security agreement to
     secure the obligations to any person or entity to be paid with such funds
     or other assets as provided in this Agreement; and

the Special Servicer and the Trustee, shall, to the extent consistent with this
Agreement, take such reasonable actions as may be necessary to ensure that, if
this Agreement were deemed to create a security interest in the Trust Fund, the
Uncertificated Regular Interests, or the other property described above, such
security interest would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Agreement. At the Depositor's direction, the Master Servicer shall file,
at the expense of the Trust Fund as an Additional Trust Fund Expense, all
filings necessary to maintain the effectiveness of any original filings
necessary under the Uniform Commercial Code as in effect in any jurisdiction to
perfect the Trustee's security interest in or lien on the Trust Fund, the
Uncertificated Regular Interests, and such other property, including without
limitation (A) continuation statements, and (B) such other statements as may be
occasioned by any transfer of any interest of the Master Servicer, the Special

Interests, or such other property. In connection herewith, the Trustee shall
have all of the rights and remedies of a secured party and creditor under the

covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Certificates or the rights of the Holders thereof.

          SECTION 11.07. LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.
                         ------------------------------------------ 

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

          No Certificateholder shall have any right to vote (except as provided
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.

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as herein before
provided, and unless the Holders of Certificates evidencing not less than 25% of
the aggregate Certificate Principal Balance evidenced by the Certificates shall
also 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; it being
understood and intended, and being 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 whatever
by virtue or by availing itself or themselves of any provisions of this
Agreement to affect, disturb or prejudice the rights of

                                      133
<PAGE>
 
the Holders of any other of the Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder or to enforce any right
under this Agreement, except in the manner herein provided and for the common
benefit of all Certificateholders.  For the protection and enforcement of the
provisions of this Section 11.07, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

          SECTION 11.08. CERTIFICATES NONASSESSABLE AND FULLY PAID.
                         ----------------------------------------- 

          It is the intention of the Depositor that Certificateholders shall not
be personally liable for obligations of the Trust Fund, that the interests in
the Trust Fund represented by the Certificates shall be nonassessable for any
reason whatsoever, and that the Certificates, upon due authentication thereof by
the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

          SECTION 11.09. RULE 144A INFORMATION.

          In addition to the other reports and information made available and
distributed to the Depositor, the Trustee or the Certificateholders pursuant to
other provisions of this Agreement, the Master Servicer shall, in accordance
with such reasonable rules and procedures as it may adopt (which may include the
requirement that an agreement governing the availability, use and disclosure of
such information, and which provides adequate indemnity to the Master Servicer,
be executed to the extent the Master Servicer deems such action to be necessary
or appropriate), also make available any additional information

review by the Depositor, the Trustee, the Certificateholders and any other
Persons to whom the Master Servicer believes such disclosure is appropriate, in
each case except to the extent doing so is prohibited by applicable law or by
any documents relating to a Mortgage Loan.

          Any recipient of information provided pursuant to this Section 11.09
shall agree that such information shall not be disclosed or used for any purpose
other than the evaluation of the Class A-X, Class E, Class F and Class G
Certificates by the prospective purchaser. The Depositor shall be responsible
for the physical delivery of the information requested pursuant to this Section
11.09.

The Trust Fund was created pursuant to the Pooling and Servicing Agreement,
dated as of December 1, 1995 (the "Agreement"), between the Depositor, Wells
Fargo Bank, National Association, as Master Servicer and as the initial Special
Servicer, ABN AMRO Bank N.V. as Fiscal Agent and LaSalle National Bank, as
Trustee, a summary of certain of the pertinent provisions of which is set forth
herein.  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.  Capitalized terms used herein but not defined shall have the
meanings assigned thereto in the Agreement.

          This Certificate is one of a duly authorized issue of certificates of
CS First Boston Mortgage Securities Corp. designated as its Commercial Mortgage
Pass-Through Certificates, Series 1995-WF1, which is comprised of eleven
Classes: the Class A-1 Certificates, the Class A-2 Certificates, the Class A-X
Certificates, the Class B Certificates, the Class C Certificates, the Class D
Certificates, the Class E Certificates, the Class F Certificates, the Class G

Reference is hereby made to the Agreement for a statement of the respective
rights and obligations thereunder of the Depositor, the Master Servicer, the
Special Servicer, the Trustee and the Fiscal Agent and the Holders of the
Certificates and the terms upon which the Certificates are issued, authenticated
and delivered.  This Certificate represents an interest in the Trust Fund, which
Trust Fund consists of, among other things, (i) the Mortgage Loans and all
distributions thereon paid or payable after the Cut-off Date, together with the
Mortgage Files relating to the Mortgage Loans, (ii) the Distribution Account and
the Collection Account and all amounts deposited therein

                                     A-1-2

pursuant to the applicable provisions of the Agreement, (iii) REO Property, (iv)
the interest of the Trust Fund in any insurance policies with respect to the
Mortgage Loans, and (v) all proceeds of the conversion, voluntary or
involuntary, of any of the foregoing into cash or other liquid property.

          This Class A-1 Certificate represents a Percentage Interest, as set
forth on the face of this Certificate, equal to the Initial Certificate
Principal Balance of this Certificate divided by the Initial Class A-1
Certificate Principal Balance, both as set forth above.

          The Trustee shall distribute from the Distribution Account, to the
extent of available funds, on the 21st day of each calendar month, or, if such
21st day is not a Business Day, the next succeeding Business Day (the
"Distribution Date"), commencing January 22, 1996, to the Person in whose name
this Certificate is registered at the close of business on the last day of the
month immediately preceding the month of such distribution (each a "Record
Date"), a principal amount equal to the product of the Percentage Interest
evidenced by this Certificate and that portion of the Available Distribution
Amount that is allocated to principal on such Class of Certificates on such
Distribution Date determined pursuant to Section 4.02 of the Agreement.

          Distributions of interest will be made on each Distribution Date, to
the extent of available funds, in an amount equal to that portion of the
Available Distribution Amount that is allocated to interest on such Class of
Certificates on such Distribution Date determined pursuant to Section 4.02 of
the Agreement.

          Not later than each Distribution Date, the Trustee will send to each
Certificateholder a statement containing information relating to the Mortgage
Loans and payments made to Certificateholders.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Holder hereof entitled thereto at the address
appearing in the Certificate Register or, if such Holder holds one or more of
the Class A-1 Certificates with an aggregate initial Certificate Principal
Balance of at least $5,000,000, by wire transfer in immediately available funds
to the account of such Certificateholder designated in writing to the Trustee at
least five Business Days prior to the applicable Record Date for the

Agent's obligations hereunder to make Advances without the consent of the Holder
of such Certificate, (ii) reduce the aforesaid percentages of Certificates, the
holders of which are required to consent to any such amendment (iii) change the
percentage of the Principal Balance of the Mortgage Loans specified in Section
10.01(a) of the Agreement relating to optional termination of the Trust Fund or
(iv) amend these provisions.  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 Depositor, the
Master Servicer, the Special Servicer, the Trustee and the Fiscal Agent to amend
certain terms and conditions set forth in the Agreement without the consent of
Holders of the Certificates.

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

certain limitations therein set forth, this Certificate is exchangeable for one
or more new Certificates of the same Class and of authorized denominations
evidencing a like aggregate Certificate Principal Balance, as requested by the
Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.  The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

          The obligations and responsibilities of the Depositor, the Trustee,
the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any
Mortgage Loan remaining in the Trust Fund, which purchase right the Master
Servicer may exercise at its sole and exclusive election as of any Distribution
Date on or after the date on which the aggregate Principal Balance of the
Mortgage Loans at the time of the purchase is less than 5% of the aggregate
Principal Balance of the Mortgage Loans as of the Cut-off Date; and (b) the
later of (i) the maturity or other liquidation (or any advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund and

entitled to any benefit under the Agreement or be valid or obligatory for any
purpose.

          IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly

thereby, (iii) change the percentage of the Principal Balance of the Mortgage

notation of such consent is made upon this Certificate. The Agreement also
permits the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent to amend certain terms and conditions set forth in the

that the aggregate of each Class of Certificates equals its respective aggregate
Certificate Principal Balance. As provided in the Agreement and subject to
certain limitations therein set forth, this Certificate is exchangeable for one
or more new Certificates of the same Class and of authorized denominations
evidencing a like aggregate Certificate Principal Balance, as requested by the
Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at

mortgage loans secured by mortgages on commercial and multifamily property (the

the Trust Fund by CS First Boston Mortgage Securities Corp. (the "Depositor").
The Trust Fund was created pursuant to the Pooling and Servicing Agreement,
dated as of December 1, 1995 (the "Agreement"), between the Depositor, Wells
Fargo Bank, National Association, as Master Servicer and as the initial Special
Servicer, ABN AMRO Bank N.V. as Fiscal Agent and LaSalle National Bank, as
Trustee, a summary of certain of the pertinent provisions of which is set forth
herein. 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. Capitalized terms used herein but not defined shall have the meanings
assigned thereto in the Agreement.

          This Certificate is one of a duly authorized issue of certificates of
CS First Boston Mortgage Securities Corp. designated as its Commercial Mortgage
Pass-Through Certificates, Series 1995-WF1, which is comprised of eleven
Classes: the Class A-1 Certificates, the Class A-2 Certificates, the Class A-X
Certificates, the Class B Certificates, the Class C Certificates, the Class D
Certificates, the Class E Certificates, the Class F Certificates, the Class G
Certificates, the Class R-I Certificates and the Class R-II Certificates.
Reference is hereby made to the Agreement for a statement of the respective
rights and obligations thereunder of the Depositor, the Master Servicer, the
Special Servicer, the Trustee and the Fiscal Agent and the Holders of the
Certificates and the terms upon which the Certificates are issued, authenticated
and delivered. This Certificate represents an interest in the Trust Fund, which
Trust Fund consists of, among other things, (i) the Mortgage Loans and all
distributions thereon paid or payable after the Cut-off Date, together with the
Mortgage Files relating to the Mortgage Loans, (ii) the Distribution Account and
the Collection Account and all amounts deposited therein pursuant to the
applicable


                                      C-3
<PAGE>
 
provisions of the Agreement, (iii) REO Property, (iv) the interest of the Trust
Fund in any insurance policies with respect to the Mortgage Loans, and (v) all
proceeds of the conversion, voluntary or involuntary, of any of the foregoing
into cash or other liquid property.

          This Class C Certificate represents a Percentage Interest, as set

Principal Balance of this Certificate divided by the Initial Class C Certificate
Principal Balance, both as set forth above.

          The Trustee shall distribute from the Distribution Account, to the
extent of available funds, on the 21st day of each calendar month, or, if such
21st day is not a Business Day, the next succeeding Business Day (the
"Distribution Date"), commencing January 22, 1996, to the Person in whose name
this Certificate is registered at the close of business on the last day of the
month immediately preceding the month of such distribution (each a "Record
Date"), a principal amount equal to the product of the Percentage Interest
evidenced by this Certificate and that portion of the Available Distribution
Amount that is allocated to principal on such Class of Certificates on such
Distribution Date determined pursuant to Section 4.02 of the Agreement.

          Distributions of interest will be made on each Distribution Date, to
the extent of available funds, in an amount equal to that portion of the
Available Distribution Amount that is allocated to interest on such Class of
Certificates on such Distribution Date determined pursuant to Section 4.02 of
the Agreement.

          Not later than each Distribution Date, the Trustee will send to each
Certificateholder a statement containing information relating to the Mortgage
Loans and payments made to Certificateholders.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Holder hereof entitled thereto at the address
appearing in the Certificate Register or, if such Holder holds one or more of
the Class C Certificates with an aggregate initial Certificate Principal Balance
of at least $5,000,000, by wire transfer in immediately available funds to the
account of such Certificateholder designated in writing to the Trustee at least
five Business Days prior to the applicable Record Date for the Distribution Date
on which wire transfers will commence. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice of the pendency
of such final distribution and only upon presentation and surrender of this
Certificate at the office or agency designated in such notice.

Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time

received on or with respect to Mortgage Loans are required to be distributed
with respect to any Certificate, or modify or alter the Master Servicer's, the

make Advances without the consent of the Holder of such Certificate, (ii) reduce
the aforesaid percentages of

without the consent of 100% of the Holders of Certificates of the Class affected
thereby, (iii) change the percentage of the Principal Balance of the Mortgage
Loans specified in Section 10.01(a) of the Agreement relating to optional
termination of the Trust Fund or (iv) amend these provisions. 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 Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent to amend certain terms and conditions set forth in the

transfer at the office or agency of the Trustee designated therefor, duly

attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class and of authorized denominations, and for the same aggregate
interest in the Trust Fund will be issued to the designated transferee or
transferees.

          The Class C Certificates will be issued in fully registered form in
minimum denominations of $100,000 Certificate Principal Balance and in integral
multiples of $1,000 in excess of such amount; provided, however, that one

Certificate Principal Balance. As provided in the Agreement and subject to
certain limitations therein set forth, this Certificate is exchangeable for one
or more new Certificates of the same Class and of authorized denominations
evidencing a like aggregate Certificate Principal Balance, as requested by the
Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

          The obligations and responsibilities of the Depositor, the Trustee,
the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any

mortgage loans secured by mortgages on commercial and multifamily property (the
"Mortgage Loans") and certain other property held in trust and transferred to
the Trust Fund by CS First Boston Mortgage Securities Corp. (the "Depositor").
The Trust Fund was created pursuant to the Pooling and Servicing Agreement,
dated as of December 1, 1995 (the "Agreement"), between the Depositor, Wells
Fargo Bank, National Association, as Master Servicer and as the initial Special
Servicer, ABN AMRO Bank N.V. as Fiscal Agent and LaSalle National Bank, as
Trustee, a summary of certain of the pertinent provisions of which is set forth

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. Capitalized terms used herein but not defined shall have the meanings
assigned thereto in the Agreement.

          This Certificate is one of a duly authorized issue of certificates of
CS First Boston Mortgage Securities Corp. designated as its Commercial Mortgage
Pass-Through Certificates, Series 1995-WF1, which is comprised of eleven
Classes: the Class A-1 Certificates, the Class A-2 Certificates, the Class A-X
Certificates, the Class B Certificates, the Class C Certificates, the Class D
Certificates, the Class E Certificates, the Class F Certificates, the Class G
Certificates, the Class R-I Certificates and the Class R-II Certificates.
Reference is hereby made to the Agreement for a statement of the respective
rights and obligations thereunder of the Depositor, the Master Servicer, the
Special Servicer, the Trustee and the Fiscal Agent and the Holders of the
Certificates and the terms upon which the Certificates are issued, authenticated
and delivered. This Certificate represents an interest in the Trust Fund, which
Trust Fund consists of, among other things, (i) the Mortgage Loans and all
distributions thereon paid or payable after the Cut-off Date, together with the
Mortgage Files relating to the Mortgage Loans, (ii) the Distribution Account and
the Collection Account and all amounts deposited therein pursuant to the

provisions of the Agreement, (iii) REO Property, (iv) the interest of the Trust
Fund in any insurance policies with respect to the Mortgage Loans, and (v) all
proceeds of the conversion, voluntary or involuntary, of any of the foregoing
into cash or other liquid property.

          This Class D Certificate represents a Percentage Interest, as set
forth on the face of this Certificate, equal to the Initial Certificate
Principal Balance of this Certificate divided by the Initial Class D Certificate
Principal Balance, both as set forth above.

          The Trustee shall distribute from the Distribution Account, to the
extent of available funds, on the 21st day of each calendar month, or, if such
21st day is not a Business Day, the next succeeding Business Day (the
"Distribution Date"), commencing January 22, 1996, to the Person in whose name
this Certificate is registered at the close of business on the last day of the
month immediately preceding the month of such distribution (each a "Record
Date"), a principal amount equal to the product of the Percentage Interest
evidenced by this Certificate and that portion of the Available Distribution
Amount that is allocated to principal on such Class of Certificates on such
Distribution Date determined pursuant to Section 4.02 of the Agreement.

          Distributions of interest will be made on each Distribution Date, to
the extent of available funds, in an amount equal to that portion of the
Available Distribution Amount that is allocated to interest on such Class of
Certificates on such Distribution Date determined pursuant to Section 4.02 of
the Agreement.

          Not later than each Distribution Date, the Trustee will send to each
Certificateholder a statement containing information relating to the Mortgage
Loans and payments made to Certificateholders.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Holder hereof entitled thereto at the address
appearing in the Certificate Register or, if such Holder holds one or more of
the Class D Certificates with an aggregate initial Certificate Principal Balance
of at least $5,000,000, by wire transfer in immediately available funds to the
account of such Certificateholder designated in writing to the Trustee at least
five Business Days prior to the applicable Record Date for the Distribution Date
on which wire transfers will commence. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice of the pendency
of such final distribution and only upon presentation and surrender of this
Certificate at the office or agency designated in such notice.

          The Agreement permits, with certain exceptions as 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 and the rights of the Certificateholders under the Agreement 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 evidencing Voting
Rights aggregating not less than 51% of outstanding Certificates affected
thereby; provided, however, that no such amendment may (i) reduce in any manner
         --------  ------- 
the amount of, delay the timing of or change the manner in which payments
received on or with respect to Mortgage Loans are required to be distributed
with respect to any Certificate, or modify or alter the Master Servicer's, the
Special Servicer's, the Trustee's or the Fiscal Agent's obligations hereunder to
make Advances without the consent of the Holder of such Certificate, (ii) reduce
the aforesaid percentages of

                                      D-4
<PAGE>
 
Certificates, the holders of which are required to consent to any such amendment
without the consent of 100% of the Holders of Certificates of the Class affected
thereby, (iii) change the percentage of the Principal Balance of the Mortgage
Loans specified in Section 10.01(a) of the Agreement relating to optional
termination of the Trust Fund or (iv) amend these provisions. 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 Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent to amend certain terms and conditions set forth in the
Agreement without the consent of Holders of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable on the
Certificate Register upon surrender of this Certificate for registration of
transfer at the office or agency of the Trustee designated therefor, duly
endorsed by, or accompanied by a written instrument of transfer in a form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class and of authorized denominations, and for the same aggregate
interest in the Trust Fund will be issued to the designated transferee or
transferees.

          The Class D Certificates will be issued in fully registered form in
minimum denominations of $100,000 Certificate Principal Balance and in integral
multiples of $1,000 in excess of such amount; provided, however, that one

Certificate of each Class may be issued in such other amount as is required so
that the aggregate of each Class of Certificates equals its respective aggregate
Certificate Principal Balance. As provided in the Agreement and subject to
certain limitations therein set forth, this Certificate is exchangeable for one
or more new Certificates of the same Class and of authorized denominations
evidencing a like aggregate Certificate Principal Balance, as requested by the
Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

          The obligations and responsibilities of the Depositor, the Trustee,
the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any
Mortgage Loan remaining in the Trust Fund, which purchase right the Master
Servicer may exercise at its sole and exclusive election as of any Distribution
Date on or after the date on which the aggregate Principal Balance of the
Mortgage Loans at the time of the purchase is less than 5% of the aggregate
Principal Balance of the Mortgage Loans as of the Cut-off Date; and (b) the
later of (i) the maturity or other liquidation (or any advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to the Agreement.

          This Class E Certificate represents a Percentage Interest, as set

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 Depositor,

certain limitations therein set forth, this Certificate is exchangeable for one
or more new Certificates of the same Class and of authorized denominations
evidencing a like aggregate Certificate Principal Balance, as requested by the
Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.  The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any

mortgage loans secured by mortgages on commercial and multifamily property (the
"Mortgage Loans") and certain other property held in trust and transferred to
the Trust Fund by CS First Boston Mortgage Securities Corp. (the "Depositor").
The Trust Fund was created pursuant to the Pooling and Servicing Agreement,
dated as of December 1, 1995 (the "Agreement"), between the Depositor, Wells
Fargo Bank, National Association, as Master Servicer and as the initial Special
Servicer, ABN AMRO Bank N.V. as Fiscal Agent and LaSalle National Bank, as
Trustee, a summary of certain of the pertinent provisions of which is set forth
herein. 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. Capitalized terms used herein but not defined shall have the meanings
assigned thereto in the Agreement.

          This Certificate is one of a duly authorized issue of certificates of
CS First Boston Mortgage Securities Corp. designated as its Commercial Mortgage
Pass-Through Certificates, Series 1995-WF1, which is comprised of eleven
Classes: the Class A-1 Certificates, the Class A-2 Certificates, the Class A-X
Certificates, the Class B Certificates, the Class C Certificates, the Class D
Certificates, the Class E Certificates, the Class F Certificates, the Class G
Certificates, the Class R-I Certificates and the Class R-II Certificates.
Reference is hereby made to the Agreement for a statement of the respective
rights and obligations thereunder of the Depositor, the Master Servicer, the
Special Servicer, the Trustee and the Fiscal Agent and the Holders of the
Certificates and the terms upon which the Certificates are issued, authenticated
and delivered. This Certificate represents an interest in the Trust Fund, which
Trust Fund consists of, among other things, (i) the Mortgage Loans and all
distributions thereon paid or payable after the Cut-off Date, together with the
Mortgage Files relating to the Mortgage Loans, (ii) the Distribution Account and
the Collection Account and all amounts deposited therein pursuant to the
applicable


                                      F-3
<PAGE>
 
provisions of the Agreement, (iii) REO Property, (iv) the interest of the Trust
Fund in any insurance policies with respect to the Mortgage Loans, and (v) all
proceeds of the conversion, voluntary or involuntary, of any of the foregoing
into cash or other liquid property.

          This Class F Certificate represents a Percentage Interest, as set
forth on the face of this Certificate, equal to the Initial Certificate
Principal Balance of this Certificate divided by the Initial Class F
Certificate Principal Balance, both as set forth above.

          The Trustee shall distribute from the Distribution Account, to the
extent of available funds, on the 21st day of each calendar month, or, if such
21st day is not a Business Day, the next succeeding Business Day (the
"Distribution Date"), commencing January 22, 1996, to the Person in whose name
this Certificate is registered at the close of business on the last day of the
month immediately preceding the month of such distribution (each a "Record
Date"), a principal amount equal to the product of the Percentage Interest
evidenced by this Certificate and that portion of the Available Distribution
Amount that is allocated to principal on such Class of Certificates on such
Distribution Date determined pursuant to Section 4.02 of the Agreement.

          Distributions of interest will be made on each Distribution Date, to
the extent of available funds, in an amount equal to that portion of the
Available Distribution Amount that is allocated to interest on such Class of
Certificates on such Distribution Date determined pursuant to Section 4.02 of
the Agreement.

          Not later than each Distribution Date, the Trustee will send to each
Certificateholder a statement containing information relating to the Mortgage
Loans and payments made to Certificateholders.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Holder hereof entitled thereto at the address
appearing in the Certificate Register or, if such Holder holds one or more of
the Class F Certificates with an aggregate initial Certificate Principal
Balance of at least $5,000,000, by wire transfer in immediately available funds
to the account of such Certificateholder designated in writing to the Trustee at
least five Business Days prior to the applicable Record Date for the
Distribution Date on which wire transfers will commence. Notwithstanding the
above, the final distribution on this Certificate will be made after due notice
of the pendency of such final distribution and only upon presentation and
surrender of this Certificate at the office or agency designated in such notice.

          The Agreement permits, with certain exceptions as 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 and the rights of the Certificateholders under the Agreement 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 evidencing Voting
Rights aggregating not less than 51% of outstanding Certificates affected
thereby; provided, however, that no such amendment may (i) reduce in any manner
         --------  -------    
the amount of, delay the timing of or change the manner in which payments
received on or with respect to Mortgage Loans are required to be distributed
with respect to any Certificate, or modify or alter the Master Servicer's, the
Special Servicer's, the Trustee's or the Fiscal Agent's obligations hereunder to
make Advances without the consent of the Holder of such Certificate, (ii) reduce
the aforesaid percentages of


                                      F-4
<PAGE>
 
Certificates, the holders of which are required to consent to any such amendment
without the consent of 100% of the Holders of Certificates of the Class affected
thereby, (iii) change the percentage of the Principal Balance of the Mortgage
Loans specified in Section 10.01(a) of the Agreement relating to optional
termination of the Trust Fund or (iv) amend these provisions. 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 Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent to amend certain terms and conditions set forth in the
Agreement without the consent of Holders of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable on the
Certificate Register upon surrender of this Certificate for registration of
transfer at the office or agency of the Trustee designated therefor, duly
endorsed by, or accompanied by a written instrument of transfer in a form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class and of authorized denominations, and for the same aggregate
interest in the Trust Fund will be issued to the designated transferee or
transferees.

          The Class F Certificates will be issued in fully registered form in
minimum denominations of [$1,000,000] Certificate Principal Balance and in
integral multiples of $1,000 in excess of such amount; provided, however, that
                                               ------- --------          
one Certificate of each Class may be issued in such other amount as is required
so that the aggregate of each Class of Certificates equals its respective
aggregate Certificate Principal Balance. As provided in the Agreement and
subject to certain limitations therein set forth, this Certificate is
exchangeable for one or more new Certificates of the same Class and of
authorized denominations evidencing a like aggregate Certificate Principal
Balance, as requested by the Holder surrendering the same.

          No service charge will be made for such registrations of transfers or
exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

          The obligations and responsibilities of the Depositor, the Trustee,
the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any
Mortgage Loan remaining in the Trust Fund, which purchase right the Master
Servicer may exercise at its sole and exclusive election as of any Distribution
Date on or after the date on which the aggregate Principal Balance of the
Mortgage Loans at the time of the purchase is less than 5% of the aggregate
Principal Balance of the Mortgage Loans as of the Cut-off Date; and (b) the
later of (i) the maturity or other liquidation (or any advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to the Agreement.

          account for investment only and not with a view to or for sale in

          investor having such knowledge and experience in financial and
          business matters, and, in particular, in such matters related to

          able to bear the economic risks of such an investment and (c) an
          "accredited investor" within the meaning of Rule 501(a) promulgated

          opportunity to review, a copy of the Pooling and Servicing Agreement
          and such other information concerning the Certificates, the Mortgage
          Loans and the Depositor as has been requested by the Purchaser from
          the Depositor or the Seller and is relevant to the Purchaser's
          decision to purchase the Certificates.

               5.   The Purchaser has not and will not nor has it authorized or
          will it authorize any person to (a) offer, pledge, sell, dispose of or

          advertising or in any other manner or (e) take any other action, that
          (as to any of (a) through (e) above) would constitute a distribution
          of any Certificate under the Act, that would render the disposition of
          any Certificate a violation of Section 5 of the Act or any state
          securities law, or that would require registration or qualification
          pursuant thereto. The Purchaser will not sell or otherwise transfer
          any of the Certificates, except in compliance with the provisions of
          the Pooling and Servicing Agreement.

          registration of transfer of any Certificate to any such plan, or to
          any person acting on behalf of or with "plan assets" of such plan,
          will not be made unless such plan or person delivers an opinion of
          counsel, addressed and satisfactory to the Trustee and the Depositor,
          to the effect that the purchase and holding of a Certificate by, on
          behalf of or with "plan assets" of such plan would not constitute or
          result in a non-exempt prohibited transaction under Section 406 of
          ERISA or Section 4975 of the Code. The Purchaser understands that
          under current law such an opinion may not be available.

STATE OF ____________  )
                          : ss.:
COUNTY OF ___________     )

         [NAME OF OFFICER], being first duly sworn, deposes and says:

          1.   That he/she is [Title of Officer] of [Name of Owner] (record or
beneficial owner of the Class [R-I] [R-II] Certificates (the "Owner")), a
[savings institution] [corporation] duly organized and existing under the laws
of [the State of ____________________] [the United States], on behalf of which
he makes this affidavit and agreement.

          2.   That the Owner (i) is not and will not be a "disqualified
organization" as of [date of transfer] within the meaning of Section 860E(e)(5)
of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) will
endeavor to remain other than a disqualified organization for so long as it
retains its ownership interest in the Class [R-I] [R-II] Certificates, and (iii)
is acquiring the Class [R-I] [R-II] Certificates for its own account or for the
account of another Owner from which it has received an affidavit and agreement
in substantially the same form as this affidavit and agreement. A "Permitted
Transferee" is any person other than a "disqualified organization". (For this
purpose, a "disqualified organization" means the United States, any state or
political subdivision thereof, any agency or instrumentality of any of the
foregoing (other than an instrumentality all of the activities of which are
subject to tax and, except for the Federal Home Loan Mortgage Corporation, a
majority of whose board of directors is not selected by any such governmental
entity) or any foreign government, international organization or any agency or
instrumentality of such foreign government or organization, any rural electric
or telephone cooperative, or any organization (other than certain farmers'
cooperatives) that is generally exempt from federal income tax unless such
organization is subject to the tax on unrelated business taxable income).

          3.   That the Owner is aware (i) of the tax that would be imposed on
transfers of Class [R-I] [R-II] Certificates to disqualified organizations under
the Code; (ii) that such tax would be on the transferor, or, if such transfer is
through an agent (which person includes a broker, nominee or middleman) for a
non-Permitted Transferee, on the agent; (iii) that the person otherwise liable
for the tax shall be relieved of liability for the tax if the transferee
furnishes to such person an affidavit that the transferee is a Permitted
Transferee and, at the time of transfer, such person does not have actual
knowledge that the affidavit is false; and (iv) that the Class [R-I] [R-II]
Certificates may be "noneconomic residual interests" within the meaning of
Treasury regulations promulgated pursuant to the Code and that the transferor of
a noneconomic residual interest will remain liable for any taxes due with
respect to the income on such residual interest, if a significant purpose of the
transfer was to enable the transferor to impede the assessment or collection of
tax.

                                      N-1
<PAGE>
 
          4.   That the Owner is aware of the tax imposed on a "pass-through
entity" holding Class [R-I] [R-II] 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 and
any person holding the Class [R-I] [R-II] Certificate as nominee for another
person.)

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

          6.   That the Owner has reviewed the restrictions set forth on the
face of the Class [R-I] [R-II] Certificates and the provisions of Section 6.02
of the Pooling and Servicing Agreement under which the Class R Certificates were
issued. The Owner expressly agrees to be bound by and to comply with such
restrictions and provisions.

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

          8.   That the Owner's Taxpayer Identification Number is _____________.

          9.   That the Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, or an estate or
trust whose income from sources without the United States 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.

          10.  That no purpose of the Owner relating to the purchase of the
Class [R-I] [R-II] Certificate by the Owner is or will be to impede the
assessment or collection of tax.

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

          12.  That the Owner has no present knowledge or expectation that it
will become insolvent or subject to a bankruptcy proceeding for so long as any
of the Certificates remain outstanding.

          13.  That no purpose of the Owner relating to any sale of the Class 
[R-I] [R-II] Certificate by the Owner will be to impede the assessment or
collection of tax.

          14.  The Owner hereby agrees to cooperate with the Trustee and to take
any action required of it by the Code or Treasury regulations thereunder
(whether now or hereafter promulgated) in order to create or maintain the REMIC
status of the Trust Fund.

          15.  The Owner hereby agrees that it will not take any action that
could endanger the REMIC status of the Trust Fund or result in the imposition of
tax on the Trust Fund unless counsel for, or acceptable to, the Trustee has
provided an opinion that such action will not result in the loss of such REMIC
status or the imposition of such tax, as applicable.

          16.  The Owner has a net worth of at least $10,000,000.

found that the Purchaser has historically paid its debts as they came due, and
found no significant evidence to indicate that the Purchaser will not continue
to pay its debts as they come due in the future.

          6.   The Purchaser has represented to the Seller that, if the
Certificate constitutes a noneconomic residual interest, it (i) understands that
as holder of a noneconomic residual interest it may incur tax liabilities in
excess of any cash flows generated by the interest, and (ii) intends to pay
taxes associated with its holding of the Certificate as they become due.

                               Very truly yours,



                               (Seller)

Certificates of the Class affected thereby, (iii) change the percentage of the

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 Depositor, the
Master Servicer, the Special Servicer, the Trustee and the Fiscal Agent to amend

transfer at the office or agency of the Trustee designated therefor, duly

attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class and of authorized denominations, and for the same aggregate
interest in the Trust Fund will be issued to the designated transferee or
transferees.

Certificate evidencing the same rights and obligations, as requested by the
Holder surrendering the same.

exchanges, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. The Trustee
and any agent of the Trustee may treat the person in whose name this Certificate
is registered as the owner hereof for all purposes, and neither the Trustee nor
any such agent thereof shall be affected by notice to the contrary.

          Five elections will be made to treat certain assets of the Trust Fund
as real estate mortgage investment conduits (each, a "REMIC") for federal income
tax purposes, and such pool of assets will be designated as "_____________,"

The "regular interests" in the ____________ shall consist of the Regular
Certificates and the "residual interest" in the _____________ shall consist of
the Uncertificated __ interest.  This Class R Certificate represents ownership
of the Uncertificated __ Interest and the Uncertificated __ Interest.

          The obligations and responsibilities of the Depositor, the Trustee,
the Fiscal Agent, the Master Servicer and Special Servicer under the Agreement
shall terminate upon the earlier of: (a) the purchase by the Master Servicer, at
its election, of all Mortgage Loans and all property acquired in respect of any
Mortgage Loan remaining in the Trust Fund, which purchase right the Master
Servicer may exercise at its sole and exclusive election as of any Distribution
Date on or after the date on which the aggregate Principal Balance of the
Mortgage Loans at the time of the purchase is less than 5% of the aggregate
Principal Balance of the Mortgage Loans as of the Cut-off Date; and (b) the
later of (i) the maturity or other liquidation (or any advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to Certificateholders
of all amounts required to be distributed to them pursuant to the Agreement.

          Any term used herein that is defined in the Agreement shall have the
meaning assigned in the Agreement, and nothing herein shall be deemed
inconsistent with that meaning. If the terms hereof are inconsistent with the
Agreement, the Agreement shall control.

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

              SELLER'S REPRESENTATIONS AND WARRANTIES IN RESPECT
                             OF THE MORTGAGE LOANS

               In respect to the Mortgage Loans, the Seller hereby makes the
following representations and warranties:

               (1)    Mortgage Loan Schedule. The information set forth with
                      ----------------------
respect to each Mortgage Loan in the Mortgage Loan Schedule is complete, true
and correct in all material respects as of the date or dates respecting which
such information is furnished, except that with respect to calculations set
forth in the Mortgage Loan Schedule based upon information provided to the
Seller from the related Mortgagors (which information the Seller has reviewed
for and concluded as to its reasonableness in accordance with its underwriting
guidelines), the Seller makes no representation as to the accuracy of the
information so provided.

               (2)    Ownership of Mortgage Loans.  Each Mortgage Loan was
                      ---------------------------
originated by the Seller and, immediately prior to the transfer and assignment
of the Mortgage Loans to the Depositor, the Seller had good and marketable title
to each Mortgage Loan; each Mortgage Loan is a whole loan and not a
participation interest in a mortgage loan; as of the Delivery Date the Seller
has full right, power and authority to transfer and assign each Mortgage Loans
to the Depositor and has validly and effectively transferred (or caused to be
transferred) to the Depositor all of the Seller's legal and beneficial interest
in and to the Mortgage Loans free and clear of any pledge, lien or security
interest created by the Seller; and to the Seller's knowledge, no Mortgagor is a
debtor in any state or federal bankruptcy or insolvency proceeding.

               (3)    Payment Record. Each Mortgage Loan is current as to all
                      --------------
payments due prior to the Cut-off Date; no payment required under each Mortgage
Loan is delinquent more than 30 days or has been delinquent more than 30 days
more than once during the twelve-month period immediately preceding the Cut-off
Date;

               (4)    Lien. With respect to each Mortgage Loan, the related
                      ----
Mortgage is a valid, subsisting and, subject to paragraph (17) hereof,
enforceable first lien on the property therein described, and the related
Mortgage Property, including all improvements thereon and all fixtures,
including, without limitations, installations and mechanical, electrical,
plumbing, heating and air conditioning systems located in or affixed to each
Mortgaged Property, is free and clear of all encumbrances and liens having
priority over the first lien of each Mortgage,except for (A) liens for real
estate taxes and assessments not yet due and payable, (B) covenants, conditions
and restrictions, rights of way, easements and other matters of the public
record as of the date of recording which are acceptable to mortgage lending
institutions generally , or which are specifically referred to in any title
insurance policy contained in the Mortgage File with respect to each Mortgage
Loan and either (1) which are referred to or otherwise considered in the
appraisal made for the originator of the Mortgage Loan, or (2) which do not
materially and adversely affect the appraised value of the related Mortgaged
Property as set forth in such appraisal or (3) which are insured over or insured
against under the applicable title insurance policy in a manner which is
generally acceptable to prudent


                                      T-1
<PAGE>
 
lending institutions, and (C) other matters to which like properties are
commonly subject and which do not materially interfere with (1) the benefits of
the security intended to be provided by the related Mortgage, (2) the use,
enjoyment, value or marketability of the related Mortgaged Property or (3) the
ability of the related Mortgagor to pay timely interest and principal on the
related Mortgage Loan. For each Mortgage Loan, there are no assignments of all
or any portion of the rents, additional rents, charges, issues or profits due
and payable or to become due and payable under any lease or other agreement
pursuant to which any Person is entitled to occupy, use or possess all or any
portion of the Mortgaged Property, which are outstanding and which have priority
to the assignment of leases and rents assigned to the Depositor.

                      The Mortgage File for each Mortgage Loan contains a
security agreement and an assignment of rents and the security agreement
(together with all Uniform Commercial Code financing statements) and the
assignment of rents each creates a valid, subsisting and, enforceable first lien
or first priority security interest in all leases, sub-leases, licenses or other
agreements pursuant to which any Person is entitled to occupy, use or possess
all or any portion of the real property subject to the related Mortgage and all
personal property subject to the security agreement (such enforceability being
subject to bankruptcy, insolvency, moratorium or other laws affecting the rights
of creditors generally, and to general principles of equity (regardless of
whether enforcement of such remedies is considered in a processing in equity or
at law)) and each assignor thereof has the full right to assign the same; the
related Mortgage, and all Uniform Commercial Code financing statements necessary
or, in accordance with the practice of prudent institutional lenders desirable,
to perfect a valid first priority lien on the security interest in all fixtures,
personal property, leases and rents constituting security for repayment of each
Mortgage Loan have been delivered to the title company and will be recorded
and/or filed in all places necessary to provide constructive notice of, or to
otherwise perfect, such lien and security interest; any and all continuations
and assignments of such financing statements have been timely filed in the
appropriate recording offices, and such financing statements perfect a valid
first priority lien in favor of the secured party thereunder; notwithstanding
the foregoing, no representation is made as to the perfection of any security
interest in rents or other personal property to the extent that possession or
control of such items or actions other than the filing of Uniform Commercial
Code financing statements are required in order to effect such perfection.

               (5)    Waivers and Modifications. None of the terms of the
                      -------------------------
Mortgage Notes and Mortgages have been impaired, waived, altered or modified in
any respect, except for eight Mortgage Loans with respect to which the related
Mortgage Interest Rates were converted from a floating rate to a fixed rate and
which were by written instruments which are part of the Mortgage File; any such
instrument has been recorded and/or filed in all places necessary to perfect or
continue the Mortgage as a valid first priority lien on the subject property
securing all rights under the Mortgage Loan as so modified.

               (6)    No Offset or Defense.  Each Mortgage Loan is not subject
                      --------------------
to any valid right of rescission, set-off, counterclaim or defense, including
the defense of usury, nor will the operation of any of the terms of the related
Mortgage Note or Mortgage, or the exercise of any right thereunder, render
either the related Mortgage Note or Mortgage unenforceable, in whole or in part,
or subject to any right of rescission, set-off, counterclaim or defense,

                                      T-2
<PAGE>
 
including the defense of usury (subject to any bankruptcy, insolvency,
moratorium or other laws affecting the enforcement of creditors' rights
generally, or by the application of the rules of equity), and no such right of
rescission, set-off, counterclaim or defense has been asserted with respect
thereto.

               (7)    Mortgage Status. No instrument of subordination,
                      ---------------
cancellation, release, waiver or satisfaction of the related Mortgage or the
terms thereof has been executed in connection with the related Mortgage Loan, in
whole or in part, and no Mortgagor has been released, in whole or in part,
except in connection with any assumption agreement which has been delivered to
the Trustee. The terms of each Mortgage do not provide for a release of any
portion of the related Mortgaged Property from the lien of such Mortgage except
upon payment-in-full.

               (8)    Condemnation. There is no proceeding pending or, to the
                      ------------
best of the Seller's knowledge, threatened for the total or partial condemnation
of any Mortgaged Property which could materially interfere with the security
intended to be provided by the related Mortgage.

               (9)    Title Insurance.  Each Mortgage Loan is covered by an ALTA
                      ---------------                                           
mortgage title insurance policy, or such other generally acceptable form of
policy or insurance acceptable to FNMA or FHLMC (or, to the extent not so
acceptable, to prudent mortgage lending institutions), issued by and the valid
and binding obligation of a title insurer acceptable to FNMA or FHLMC (or, to
the extent not so acceptable, to prudent mortgage lending institutions) and, at
the time of issuance thereof, qualified to do business in the jurisdiction where
the property subject to the related Mortgage is located, insuring the Seller to
the first priority lien of each Mortgage in the original principal amount of the
Mortgage Loan subject only to such matters to which like properties are commonly
subject and which do not materially interfere with the benefits of the security
intended to be provided by each Mortgage or the use, enjoyment, value or
marketability of the related Mortgaged Property, and which are set forth
therein; the Seller is the sole named insured of any such mortgage title
insurance policy, the assignment to the Certificateholders of such mortgage
title insurance policy does not require the consent of or notification to the
insurer and such mortgage title insurance policy is in full force and effect and
will be in full force and effect and inure to the benefit of Certificateholders
upon the consummation of the transactions contemplated by this Agreement; no
claims have been made under any such mortgage title insurance policy and the
Seller has not done, by act or omission, anything which would impair the
coverage of such mortgage title insurance policy. The Seller believes that the
insurer issuing each policy is qualified to do business in the jurisdiction in
which the related Mortgaged Property is located. Each policy contains no
exclusion for or affirmatively insures (a) access to a public road and (b) that
there are no encroachments of any part of the buildings thereon over easements
(except for any Mortgaged Property located in jurisdictions where such
affirmative insurance is not available).

               (10)   No Holdbacks.  The proceeds of each Mortgage Loan have
                      ------------
been fully disbursed and there is no requirement for future advances thereunder.
All costs, fees and expenses payable to the Seller in connection with the making
of each Mortgage Loan have been paid.

               (11)   No Mortgage Default.  There is no payment default and, to
                      -------------------
the best of Seller's knowledge, no other default, breach, violation or event of
acceleration under any Mortgage Note, Mortgage or Lease Assignment that would
impair the value of the related Mortgage Loan in any material respect and no
event which, with the passage of time or the giving of notice, or both, would
constitute a material default or event of acceleration, nor has the Seller
waived any such default, and no foreclosure action or other form of enforcement
has been commenced with respect to any Mortgage.

               (12)   Other Collateral.  With respect to each Mortgage Loan, the
                      ----------------                                          
related Mortgage Note is not and has not been secured by any collateral except
the lien of the corresponding Mortgage (or any related security agreement).

               (13)   Condition of Mortgaged Property. Each Mortgaged Property
                      ------------------------------- 
is in good repair and condition (normal wear and tear excepted), free of any
material damage so as to materially adversely affect the value of such Mortgaged
Property, except as disclosed in the engineer's report, if any, delivered as
part of the Mortgage File.

               (14)   Environmental Assessment. A third party unaffiliated with
                      ------------------------
the Seller has conducted a "Phase I" environmental assessment on the Mortgaged
Property in connection with the origination of the Mortgage Loan and, based upon
the Seller's review of such assessment, to the best knowledge of the Seller, no
environmental condition exists on the Mortgaged Property which (1) constitutes a
material violation of any applicable Environmental Laws the violation of which,
individually or in the aggregate, would have a material adverse effect on the
value of the related Mortgaged Property, (2) would have a material adverse
effect on the use, value or operation of the Mortgaged Property, or (3) would
materially affect the Borrower's ability to pay timely the interest and
principal on the related Mortgage Loan. The Seller has not received any notices
(or copies thereof) issued by any governmental authority or agency of violation
of Environmental Laws with respect to any Mortgaged Property.

               (15)   Insurance. Each Mortgaged Property and all improvement
                      ---------

either a "B+" rating by the A.M. Best's Key Rating Grade or a "A" rating (or an
equivalent rating) by a nationally recognized rating agency against (i) loss by
fire and hazards covered by extended coverage in an amount not less than the
lesser of the amount of the Mortgage Loan or the replacement cost of the
Mortgaged Property, such policies contain a standard mortgage clause naming the
Mortgagee and its successors in interest as a loss payee; (ii) business
interruptions or rental loss insurance, in an amount at least equal to 12 month
s of operations of the related Mortgaged Property; (iii) flood insurance (if any
portion of the Mortgaged Property is located in an area identified by the
Federal Emergency Management Agency as having special hazards; (iv)
comprehensive general liability insurance in amounts as are generally required
by commercial mortgage lenders, and in any event not less than $1 million per
occurrence; and (v) workers' compensation insurance. The insurance coverage
described in this paragraph requires at least 30 days prior notice to the holder
at termination or cancellation, and no such notice has been received which
remains uncured; and each Mortgage obligates the related Mortgagor thereunder to
maintain all such insurance at the Mortgagor's cost and expense, and upon such
Mortgagor's failure to do so, authorizes the holder of the


                                      T-4
<PAGE>
 
Mortgage to obtain and maintain such insurance at such Mortgagor's cost and
expense and to seek reimbursement therefor from such Mortgagor.

               (16)   Mortgage Files.  The Mortgage File for each Mortgage Loan
                      --------------

genuine, and each is the legal, valid and binding obligation of the maker
thereof, enforceable in accordance with its terms, such enforceability being
subject to bankruptcy, insolvency, moratorium or other laws affecting the rights
of creditors generally, and to general principles of equity (regardless of
whether enforcement of such remedies is considered in a proceeding in equity or
at law); and to the Seller's knowledge, all parties to the related Mortgage Note
had legal capacity to enter into, execute and deliver the same and the related
Mortgage Note has been duly and properly executed by such parties.

               (18)   Local Law Compliance.  All inspections, licenses and
                      --------------------                                
certificates, including certificates of occupancy, to be made or issued with

of the Seller's knowledge, are in full force and effect, and to the Seller's
knowledge, each Mortgaged Property is in compliance with applicable laws,

Mortgaged Property the violation of which, individually or in the aggregate,
would not have a material adverse effect on the value of the related Mortgaged
Property.

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

knowledge, there are no asserted claims for material unpaid amounts which are
currently due and payable that under applicable law could give rise to such
lien, affecting the related Mortgaged Property and which are or may be a lien
prior to, or equal or coordinate with, the lien of the related Mortgage, unless
the same are insured over or insured against under the applicable title
insurance policy in a manner which is generally acceptable to prudent lending
institutions.

               (21)   Fee Simple. Each Mortgaged Property consists of an estate

               (23)   Due on Sale. Each related Mortgage contains provisions for
                      -----------
the acceleration of the payment of the unpaid principal balance of each Mortgage
Loan if, without the prior written consent of the holder, the property subject
to the Mortgage, or any interest therein, is directly or indirectly transferred
or sold, except to the extent permitted under the terms of the Mortgage.

               (24)   No Advances. The Seller has not advanced funds for the

material amount required by the Mortgage, or induced, solicited or knowingly
received any advance of funds by a party other than the Mortgagor, directly or
indirectly, for the payment of any amount required by the related Mortgage Note,
except for interest accruing from the date of the Mortgage Note or date of
disbursement of the proceeds, whichever is greater, to the day which precedes by
one month the Due Date of the first installment of principal and interest.

               (25)   Real Property. Each Mortgage Loan is principally secured
                      -------------
by an interest in real property within the meaning of Treasury Regulations
Section 1.860G-2(a)(1) as in effect on the date hereof.

                      -------------------------
of each Mortgage Loan and, to the best of the Seller's knowledge, as of the

File.

               (28)   Appraisal. In connection with the origination of each
                      ---------
Mortgage Loan, the related Mortgaged Property was appraised by a qualified
appraiser approved by the Seller who, to the best of the Seller's knowledge, had
no interest, direct or indirect, in the Mortgaged Property or in any loan made
on the security thereof, and whose compensation was not affected by the approval
or disapproval of the Mortgage Loan; each appraisal was on a form acceptable to
FNMA or FHLMC with such riders as are acceptable to FNMA and FHLMC, as the case
may be, or was on a form that would have been acceptable to prudent mortgage
lending institutions at the time of origination.

                      -------------------
assignments of leases for each Mortgage Loan contain customary and enforceable
provisions for commercial mortgage loans secured by properties such as the
Mortgaged Properties, so as to render the rights and remedies of the holder
adequate for the realization against the Mortgaged Property of the benefits of
the security, including realization by judicial, or if applicable, nonjudicial
foreclosure, subject to the effect of bankruptcy and similar laws affecting the
rights of creditor and the application of principles of equity.

information contained on such schedule of leases is true in all material
