     Pooling and Servicing  Agreement,  dated as of March 30, 1998, among Nomura
Asset Securities Corporation, as Depositor, AMRESCO Services, L.P., as Servicer,
CRIIMI MAE Services Limited  Partnership,  as initial Special Servicer,  LaSalle
National Bank, as Trustee, and ABN AMRO Bank N.V., as Fiscal Agent.


                             PRELIMINARY STATEMENT:

 (Terms  used but not  defined  in this  Preliminary  Statement  shall  have the
meanings specified in Article I hereof)

     The  Depositor  intends  to sell  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. As provided herein,  the Trustee will elect that the Trust Fund,
exclusive of the Lock-Box Accounts, Cash Collateral Accounts,  Reserve Accounts,
the Default  Interest,  the Default Interest  Distribution  Account,  the Excess
Interest and the Excess Interest Distribution Account (such portion of the Trust
Fund,  the "Trust  REMICs"),  be treated for federal  income tax purposes as two
separate real estate  mortgage  investment  conduits (each, a "REMIC" or, in the
alternative,  the "Lower-Tier REMIC" and the "Upper-Tier REMIC,"  respectively).
The Class A-1A,  Class A-1B,  Class A-1C,  Class A-CS1,  Class PS-1,  Class A-2,
Class A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6, Class B-7 and Class B-7H Certificates  constitute "regular
interests" in the Upper-Tier  REMIC and the Class R Certificates  constitute the
sole Class of "residual  interests" in the Upper-Tier  REMIC for purposes of the
REMIC  Provisions.  The  Class LR  Certificates  constitute  the  sole  Class of
"residual  interests"  in  the  Lower-Tier  REMIC  for  purposes  of  the  REMIC
Provisions.  There are also 16  Classes  of  uncertificated  Lower-Tier  Regular
Interests issued under this Agreement (the Class A-1A1-L,  Class A-1A2-L,  Class
A-1B-L,  Class A-1C-L, Class A-2-L, Class A-3-L, Class A-4-L, Class A-5-L, Class
B-1-L,  Class B-2-L,  Class B-3-L,  Class B-4-L, Class B-5-L, Class B-6-L, Class
B-7-L and Class  B-7H-L  Interests),  each of which  will  constitute  a regular
interest in the Lower-Tier REMIC. All such Lower-Tier  Regular Interests will be
held by the Trustee as assets of the Upper-Tier  REMIC.  The parties intend that
the portions of the Trust Fund  representing the Default  Interest,  the Default
Interest  Distribution  Account,  the Excess  Interest  and the Excess  Interest
Distribution  Account will be treated as a grantor trust under Subpart E of Part
1 of  Subchapter J of the Code,  that the Class V-1  Certificates  represent pro
rata undivided  beneficial interests in the portion of the Trust Fund consisting
of the Default Interest,  subject to the obligations to pay the Advance Interest
Amount,  and the Default  Interest  Distribution  Account and that the Class V-2
Certificates represent pro rata undivided beneficial interests in the portion of
the Trust  Fund  consisting  of the  Excess  Interest  and the  Excess  Interest
Distribution Account.

     The  following  table  sets forth the  designation  and  aggregate  initial
Certificate  Balance  (or,  with  respect  to the Class  A-CS1  and  Class  PS-1
Certificates,  Notional  Balance)  for  each  Class of  Certificates  comprising
interests in the Upper-Tier REMIC.

(1) The initial  Notional  Balance of the Class A-CS1  Certificates  is equal to
$200,000,000  (the initial  Certificate  Balance of the Class A-1A  Certificates
minus $311,492,100).

(2) The  initial  Notional  Balance of Class PS-1  Certificates  is equal to the
aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date.

(3)      Rating Agencies (S&P, Fitch, DCR, Moody's)

     The initial  Certificate Balance of each of the Class V-1, Class V-2, Class
R and Class LR  Certificates  is zero.  Additionally,  the Class V-1, Class V-2,
Class  R and  Class  LR  Certificates  do  not  have  a  Notional  Balance.  The
Certificate  Balance  of any  Class  of  Certificates  outstanding  at any  time
represents the maximum  amount which holders  thereof are entitled to receive as
distributions  allocable to principal  from the cash flow on the Mortgage  Loans
and the other  assets in the Trust Fund;  provided,  however,  that in the event
that amounts previously  allocated as Realized Losses to a Class of Certificates
in reduction  of the  Certificate  Balance  thereof are  subsequently  recovered
(including without limitation after the reduction of the Certificate  Balance of
such Class to zero),  such Class may  receive  distributions  in respect of such
recoveries in accordance with the priorities set forth in Section 4.01.

     As of the  Cut-off  Date,  the  Mortgage  Loans  have an  aggregate  Stated
Principal Balance equal to approximately $3,722,686,278.

     In consideration of the mutual agreements herein contained,  the Depositor,
the Servicer,  the initial  Special  Servicer,  the Trustee and the Fiscal Agent

equal  to the  excess,  if any,  of (a) the  Stated  Principal  Balance  of such
Mortgage Loan over (b) the excess of (i) 90% of the sum of the appraised  values
of the related Mortgaged Properties as determined by Updated Appraisals obtained
by the Servicer of the  Mortgaged  Properties  securing  such Mortgage Loan over
(ii) the sum of (A) to the extent not previously  advanced by the Servicer,  the
Trustee or the Fiscal Agent,  all unpaid interest on such Mortgage Loan at a per

within the last 12 months  prior to the first  Distribution  Date on or after an
Appraisal Reduction Event has occurred, the Servicer shall estimate the value of
the related Mortgaged Properties (the "Servicer's  Appraisal Estimate") and such
estimate  shall be used for  purposes of  determining  the  Appraisal  Reduction
Amount for such  Distribution  Date.  Within 60 days (or such shorter  period as
practical)  after the  Servicer  receives  notice or is  otherwise  aware of the
Appraisal  Reduction Event, the Servicer shall obtain an Updated  Appraisal.  On
the  first  Distribution  Date  occurring  on or  after  the  delivery  of  such
appraisal, the Servicer shall adjust the Appraisal Reduction Amount to take into
account such appraisal (regardless of whether the Updated Appraisal is higher or
lower than the Servicer's Appraisal  Estimate).  Each Appraisal Reduction Amount

amount of Monthly  Payments on the Mortgage Loan (unless  during such  extension
period the borrower has been  delinquent for 60 days or more, in which case, the
first  Distribution Date following such 60 day delinquency),  (ii) 60 days after
an uncured  Delinquency  (without regard to the application of any grace period)
occurs in respect of such Mortgage Loan,  (iii) the date on which a reduction in
the amount of Monthly  Payments on such Mortgage  Loan, or a change in any other
material  economic  term of such  Mortgage  Loan (other than an extension of the
Maturity Date), becomes effective as a result of a modification of such Mortgage
Loan by the Special Servicer,  (iv) the date a receiver has been appointed,  (v)
the date a borrower declares  bankruptcy,  (vi) the date a Mortgage Loan becomes

the value of a Mortgaged  Property and security for the related  Mortgage  Loan.
The  Special  Servicer  shall  notify the  Servicer  within five (5) days of its
becoming aware of the occurrence of any of the foregoing events.

     "ARD Loan":  A Mortgage  Loan that  substantially  fully  amortizes  by its
maturity date but provides for a date on which a substantial amount of principal
will be due if the Borrower  elects to prepay the Mortgage  Loan in full on such
date (such date, the "Anticipated Repayment Date"). An ARD Loan provides for the
establishment  of a lock box  (generally  three  months to one year prior to the
Anticipated  Repayment  Date) if one is not  already  in  place,  and  after the
Anticipated Repayment Date, for the application of all cash flow not used to pay
scheduled amounts due on the Mortgage Loan and operating  expenses to reduce the
principal balance of the Mortgage Loan and an increased interest rate.

     "Assignment  of Leases,  Rents and Profits":  With respect to any Mortgaged
Property,  any  assignment  of leases,  rents and  profits or similar  agreement
executed by the Borrower,  assigning to the  mortgagee all of the income,  rents
and profits derived from the ownership, operation, leasing or disposition of all
or a portion of such  Mortgaged  Property,  in the form which was duly executed,
acknowledged and delivered,  as amended,  modified,  renewed or extended through
the date hereof and from time to time hereafter.

     "Assignment  of  Mortgage":  An assignment  of Mortgage  without  recourse,
notice of  transfer or  equivalent  instrument,  in  recordable  form,  which is
sufficient  under the laws of the  jurisdiction  in which the related  Mortgaged

assignment,  notice of transfer or equivalent  instrument  may be in the form of
one  or  more  blanket  assignments  covering  Mortgages  encumbering  Mortgaged
Properties located in the same jurisdiction,  if permitted by law and acceptable
for recording;  provided,  however, that none of the Trustee, the Custodian, the
Special  Servicer and the Servicer shall be responsible for determining  whether
any assignment is legally sufficient or in recordable form.

Balloon  Loan,  the maturity  date of such  Mortgage  Loan.  With respect to any
Balloon Loan,  the date on which such Mortgage Loan would be deemed to mature in
accordance with its original amortization schedule absent its Balloon Payment.

     "Assumed  Scheduled  Payment":  With respect to any  Mortgage  Loan that is
delinquent in respect of its Balloon Payment (including any REO Mortgage Loan as
to which the Balloon  Payment  would have been past due), an amount equal to the
sum of (a) the principal portion of the Monthly Payment that would have been due
on such Mortgage Loan on the related Due Date (or portion thereof not received),
based on the constant  Monthly Payment that would have been due on such Mortgage
Loan on the  related  Due Date based on the  constant  payment  required  by the
related Note or the amortization or payment schedule thereof (as calculated with
interest at the related  Mortgage Rate) (if any),  assuming such Balloon Payment
had not become  due,  after  giving  effect to any prior  modification,  and (b)
interest at the applicable Mortgage Pass-Through Rate.

pursuant to Section 3.20.

     "Available  Funds":  For a Distribution Date, the sum of (i) all previously
undistributed  Monthly  Payments,  Minimum  Defaulted  Monthly Payments or other
receipts on account of principal and interest  (including  Unscheduled  Payments

at the Lower  Rate,  the  Special  Servicer  shall not  agree to  payments  with

after notice to all  Certificateholders,  Holders of Certificates  evidencing at

that for purposes of calculating  distributions on the  Certificates,  Principal
Prepayments  with respect to any Mortgage  Loan are deemed to be received on the
date  they are  applied  in  accordance  with  Section  3.01(b)  to  reduce  the
outstanding principal balance of such Mortgage Loan on which interest accrues.

     (c) Any  amounts  received  in  respect  of a  Mortgage  Loan as to which a
default has occurred and is  continuing in excess of Monthly  Payments  shall be
applied to Default Interest and other amounts due on such Mortgage Loan prior to
the application to late fees.

     SECTION 1.03. Certain Constructions.

     For purposes of the definitions of "Minimum  Defaulted Monthly Payment" and
"Special  Servicing  Fee Rate",  and Section 3.19,  Section 3.12,  Section 3.25,

zero. For purposes of this Agreement, the Class V-1 Certificates shall be deemed

outstanding  that  provide  for the payment of Excess  Interest,  the Class B-7H
Certificates  and the Class B-7H-L Interest shall be deemed to be outstanding so

Lock-Box  Accounts to be  transferred to and held in the name of the Servicer on
behalf  of the  Trustee  as  successor  to the  Mortgage  Loan  Sellers  and the

     On or promptly  following  the Closing  Date,  the Servicer  shall,  to the
extent  possession  of  recorded  copies  of each  Mortgage  and  the  documents
described in Sections  2.01(a)(iv),  (v), (viii),  (xii),  (xiii) and (xiv) have
been  delivered to it, at the expense of the  Depositor,  (1) prepare and record
(a) each Assignment of Mortgage  referred to in Section  2.01(a)(iii)  which has
not yet been submitted for recording and (b) each  Reassignment of Assignment of
Leases, Rents and Profits referred to in Section 2.01(a)(viii) (if not otherwise
included in the related Assignment of Mortgage) which has not yet been submitted

submit (and in no event later than 30 Business Days following the receipt of the
related  documents  in the case of clause 1(a) above and 60 days  following  the
receipt of the applicable documents in the case of clauses 1(b) and 2 above) for
recording or filing,  as the case may be, in the  appropriate  public  recording

receipt of the original  recorded copy (and in no event later than five Business
Days   following   such  receipt)   deliver  such  original  to  the  Custodian.
Notwithstanding  anything to the contrary  contained in this  Section  2.01,  in
those instances where the public recording office retains the original Mortgage,
Assignment  of Mortgage  or  Reassignment  of  Assignment  of Leases,  Rents and
Profits, if applicable,  after any has been recorded,  the obligations hereunder
of the  Depositor  shall be deemed to have been  satisfied  upon delivery to the
Custodian of a copy of such Mortgage,  Assignment of Mortgage or Reassignment of
Assignment of Leases, Rents and Profits, if applicable,  certified by the public
recording  office  to be a true  and  complete  copy  of the  recorded  original
thereof.  If a pro  forma  title  insurance  policy  has been  delivered  to the
Custodian in lieu of an original  title  insurance  policy,  the Depositor  will
promptly  deliver to the Custodian the related  original title insurance  policy
upon receipt thereof. The Depositor shall promptly cause the UCC-1's referred to
in Section  2.01(a)(v) to be filed in the applicable public recording office and
upon filing will  promptly  deliver to the  Custodian  the related  UCC-1,  with
evidence of filing  thereon.  The Depositor shall reimburse the Servicer for all
out-of-pocket  expenses  incurred  and  filing  fees  paid  by the  Servicer  in
connection  with its  obligations  under this  paragraph.  Copies of recorded or
filed Assignments,  Reassignments, UCC-1's and UCC-3's shall be delivered to the
Trustee by the Depositor or Servicer, as applicable.

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

     (b) The Mortgage Loan known as the Westin  Casuarina Resort Loan is secured
by the property  known as the Westin  Casuarina  Resort (the  "Westin  Casuarina
Resort Property").  The Westin Casuarina Resort Property also serves as security
for  another  loan made by NACC to  Galleon  Beach  Resort,  Ltd.  (the  "Westin
Casuarina  Borrower")  on August 7, 1997 (the "Other  Westin  Casuarina  Loan"),
which had an  original  principal  balance  of  $50,000,000.  The  Other  Westin
Casuarina  Loan is included  in the trust fund  created in  connection  with the
issuance of Asset Securitization  Corporation,  Commercial Mortgage Pass-Through
Certificates,  Series 1997-D5  ("Series  1997-D5").  The Westin Casuarina Resort
Loan and the Other  Westin  Casuarina  Loan are pari passu  loans,  entitled  to
payments made by the Westin  Casuarina  Borrower and other  amounts  received in
respect of the Westin Casuarina Resort Property pro rata on the basis of amounts
owing under each such loan.

     In connection with the origination of the Westin Casuarina Resort Loan, the
trustee of Series 1997-D5 (which is LaSalle National Bank) and NACC entered into
the  Westin  Casuarina  Co-Lender  Agreement.  Under  the  terms  of the  Westin
Casuarina  Co-Lender  Agreement,  the  servicer  of  Series  1997-D5  (which  is
presently the same entity that is serving as the initial  Servicer) will service
both the Westin Casuarina Resort Loan and the Other Westin Casuarina Resort Loan
and  the  special  servicer  of  Series  1997-D5  (which  is  initially  AMRESCO
Management, Inc.) will, to the extent necessary, special service both the Westin
Casuarina  Resort Loan and the Other Westin  Casuarina Resort Loan, in each case
under  the  terms of the  pooling  and  servicing  agreement  related  to Series
1997-D5.  The Servicer (although initially the same entity acting as servicer of
1997-D5) will therefore not directly  service the Westin  Casuarina  Resort Loan
(except that the Servicer will be required to advance  delinquent  payments) and
the  Special  Servicer  will not have the ability to direct any  foreclosure  or
workout of the Westin  Casuarina  Resort Loan and the Directing Holder will have
no rights to direct  actions of the Special  Servicer with respect to the Westin
Casuarina Resort Loan.

     Each of the Mortgage Loans known as the Park LaBrea Loan,  the  Springfield
Mall Loan and the Atlanta Marriott  Marquis Loan (the "Special  Mortgage Loans")
are secured by Mortgaged Properties which also serve as security for other loans
made by NACC (the "Other  Mortgage  Loans").  The Other  Mortgage  Loans will be
included in trust funds created in connection  with issuance of separate  series
of commercial mortgage pass-through certificates.  Each Special Mortgage Loan is
a pari passu  loan,  and each is entitled  to  payments  made by the  respective
borrower and other amounts received in respect of the related Mortgaged Property
pro rata on the basis of amounts owing under each such loan.

     Pursuant  to the  terms of the  Co-Lender  Agreements,  the  Servicer  will
service both the Special  Mortgage Loans and the Other Mortgage  Loans,  and the
Special  Servicer  will,  to the extent  necessary,  specially  service both the
Special Mortgage Loans and the Other Mortgage Loans, in each case, in accordance
with the terms hereof.

     SECTION 2.02.  Acceptance by Custodian and the Trustee.

     If the Depositor cannot deliver any original or certified recorded document
described in Section 2.01 on the Closing Date, the Depositor  shall use its best
efforts,  promptly  upon receipt  thereof and in any case not later than 45 days
from the Closing Date, to deliver such original or certified  recorded documents
to the  Custodian  (unless the  Depositor is delayed in making such  delivery by
reason of the fact  that such  documents  shall  not have been  returned  by the
appropriate recording office in which case it shall notify the Custodian and the
Trustee  in  writing  of such  delay and shall  deliver  such  documents  to the
Custodian promptly upon the Depositor's  receipt thereof).  By its execution and
delivery of this Agreement, the Trustee acknowledges the assignment to it of the
Mortgage  Loans in good faith without notice of adverse claims and declares that
the Custodian holds and will hold such documents and all others  delivered to it
constituting  the Mortgage  File (to the extent the documents  constituting  the
Mortgage  File are actually  delivered to the  Custodian)  for any Mortgage Loan
assigned to the  Trustee  hereunder  in trust,  upon the  conditions  herein set
forth,  for the use and benefit of all  present  and future  Certificateholders.
With the exception of any Notes listed by the Trustee on an exception report and
delivered to the Depositor on the Closing Date, the Trustee hereby  acknowledges
the receipt of the Notes or, if applicable,  a lost note affidavit.  The Trustee
agrees to review  each  Mortgage  File within 90 days after the later of (a) the
Trustee's  receipt of such  Mortgage  File or (b) execution and delivery of this
Agreement,  to ascertain that all documents (other than documents referred to in
clause  (ix) of  Section  2.01(a)  which  shall be  delivered  to the  Servicer)
referred to in Section 2.01 above (in the case of the  documents  referred to in
Section 2.01(a)(iv),  (v), (vi), (vii) (in the case of any endorsement thereto),
(viii),  (x) through (xiv),  (xvi) and (xvii), as identified to it in writing by
the  Depositor)  and any original  recorded  documents  referred to in the first
sentence of this Section  included in the delivery of a Mortgage  File have been
received,  have been executed,  appear to be what they purport to be, purport to
be  recorded  or filed (as  applicable)  and have not been  torn,  mutilated  or
otherwise  defaced,  and  that  such  documents  relate  to the  Mortgage  Loans
identified in the Mortgage Loan Schedule.  In so doing,  the Trustee may rely on
the  purported due  execution  and  genuineness  of any such document and on the
purported  genuineness  of any signature  thereon.  If at the conclusion of such
review any document or documents constituting a part of a Mortgage File have not
been executed or received,  have not been recorded or filed (if  required),  are
unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule, appear
not to be what they  purport to be or have been  torn,  mutilated  or  otherwise
defaced,  the Trustee  shall  promptly so notify the  Depositor and the Mortgage
Loan  Seller by  providing a written  report,  setting  forth for each  affected
Mortgage  Loan,  with  particularity,  the  nature of the  defective  or missing
document.  The  Depositor  shall,  or shall cause the  applicable  Mortgage Loan
Seller to, deliver an executed,  recorded or undamaged document,  as applicable,
or, if the failure to deliver such document in such form has a material  adverse
effect on the security provided by the related Mortgaged Property, the Depositor
shall, or shall cause the responsible  Mortgage Loan Sellers to,  repurchase the
related  Mortgage  Loan in the  manner  provided  in Section  2.03.  None of the
Servicer,  the Special  Servicer and the Trustee  shall be  responsible  for any
loss,  cost,  damage or expense to the Trust Fund  resulting from any failure to
receive any document  constituting  a portion of a Mortgage File noted on such a
report or for any failure by the  Depositor  to use its best  efforts to deliver
any such document.

     In  reviewing  any Mortgage  File  pursuant to the  preceding  paragraph or
Section 2.01, the Servicer shall have no responsibility to cause the Trustee to,
and the Trustee will have no  responsibility  to, determine whether any document
or opinion is legal,  valid,  binding or  enforceable,  whether  the text of any
assignment  or  endorsement  is  in  proper  or  recordable  form  (except,   if
applicable,  to determine if the Trustee is the assignee or  endorsee),  whether
any  document  has been  recorded in  accordance  with the  requirements  of any
applicable  jurisdiction,  whether  a blanket  assignment  is  permitted  in any
applicable  jurisdiction,  or  whether  any Person  executing  any  document  or
rendering any opinion is authorized to do so or whether any signature thereon is
genuine.

     The  Trustee  shall hold that  portion of the Trust Fund  delivered  to the
Trustee consisting of "instruments" (as such term is defined in Section 9-105(i)
of the Uniform  Commercial  Code as in effect in Illinois on the date hereof) in
Illinois and, except as otherwise specifically provided in this Agreement, shall
not remove such instruments from Illinois, as applicable,  unless it receives an
Opinion  of  Counsel  (obtained  and  delivered  at the  expense  of the  Person
requesting the removal of such  instruments from Illinois) that in the event the
transfer of the Mortgage Loans to the Trustee is deemed not to be a sale,  after
such  removal,  the Trustee will  possess a first  priority  perfected  security
interest in such instruments.

     SECTION 2.03. Representations, Warranties and Covenants of the Depositor.

     (a) The Depositor hereby represents and warrants that:

       (i)    The Depositor is a corporation  duly organized,  validly  existing
              and in good standing under the laws of the State of Delaware;

       (ii)   The  Depositor  has taken all  necessary  action to authorize  the
              execution,  delivery and  performance of this Agreement by it, and
              has the power and  authority to execute,  deliver and perform this
              Agreement and all the transactions contemplated hereby, including,
              but not limited to, the power and  authority  to sell,  assign and
              transfer the Mortgage Loans in accordance with this Agreement;

       (iii)  This Agreement has been duly and validly authorized,  executed and
              delivered by the  Depositor  and  assuming the due  authorization,
              execution  and  delivery  of this  Agreement  by each other  party
              hereto, this Agreement and all of the obligations of the Depositor
              hereunder  are the legal,  valid and  binding  obligations  of the
              Depositor,  enforceable  in  accordance  with  the  terms  of this
              Agreement,   except  as  such   enforcement   may  be  limited  by
              bankruptcy, insolvency, reorganization, liquidation, receivership,
              moratorium  or other  laws  relating  to or  affecting  creditors'
              rights generally,  or by general  principles of equity (regardless
              of whether such  enforceability  is  considered in a proceeding in
              equity or at law);

       (iv)   The execution and delivery of this  Agreement and the  performance
              of its  obligations  hereunder by the Depositor  will not conflict
              with any provision of its certificate of  incorporation or bylaws,
              or any law or  regulation  to which the  Depositor is subject,  or
              conflict with, result in a breach of or constitute a default under
              (or an event  which  with  notice  or lapse of time or both  would
              constitute  a  default  under)  any of the  terms,  conditions  or
              provisions  of any  agreement or instrument to which the Depositor
              is a party  or by  which  it is  bound,  or any  order  or  decree
              applicable  to  the  Depositor,  or  result  in  the  creation  or
              imposition  of  any  lien  on any of  the  Depositor's  assets  or
              property,  which would materially and adversely affect the ability
              of the  Depositor to carry out the  transactions  contemplated  by
              this Agreement. The Depositor has obtained any consent,  approval,
              authorization or order of any court or governmental agency or body
              required  for  the  execution,  delivery  and  performance  by the
              Depositor of this Agreement;

       (v)    The certificate of  incorporation  of the Depositor  provides that
              the  Depositor  is  permitted  to  engage  in only  the  following
              activities:

               (A)  to acquire,  own,  hold,  sell,  transfer,  assign,  pledge,
                    finance, refinance and otherwise deal with (I) loans secured
                    by  first or  second  mortgages,  deeds of trust or  similar
                    liens   on   residential,    including   single-family   and
                    multi-family, commercial or mixed commercial and residential
                    properties,  shares  issued by  private  non-profit  housing
                    corporations,  or manufactured  housing contracts,  (II) any

               (B)  to  authorize  and  issue  one  or  more  series  (each,   a
                    "Pass-Through    Series")   of    pass-through    securities
                    ("Certificates")   pursuant   to   pooling   and   servicing
                    agreements (each, a "Pooling and Servicing Agreement"), each
                    of which  Pass-Through  Series (I)  represents  an ownership
                    interest in Mortgage Loans or Receivables,  related property

                    structured  to contain one or more classes of  Certificates,
                    each  class  having  the  characteristics  specified  in the

                    Series") of debt obligations ("Bonds"), each issued pursuant
                    to an indenture ("Indenture"), each of which bond series (I)
                    is  collateralized  by Mortgage  Loans,  receivables and any
                    supplemental  collateral  (the  "Supplemental   Collateral";
                    Mortgage  Loans,  Receivables and  Supplemental  Collateral,
                    collectively,  the  "Collateral")  and/or  related  property

                    classes of Bonds of any Bond Series; provided, however, that
                    the Bonds of any Bond  Series  have been rated in one of the
                    two  highest  rating  categories  by one or more  nationally
                    recognized   statistical   rating  agencies  and,   provided
                    further,  that the Bonds of any Bond  Series  other than the
                    initial Bond Series issued by a Trust have been rated in the
                    same  or  a  higher  rating   category  by  the   nationally
                    recognized  statistical rating agency or agencies that rated
                    the initial Bond Series issued by such Trust;

               (D)  to  issue,  acquire,  assume,  own,  hold,  sell,  transfer,
                    assign,   pledge  and  finance   indebtedness  that  (I)  is
                    subordinated  to  the  Bonds;  (II)  is  nonrecourse  to the
                    Depositor  and the related  Trust other than to cash flow on
                    the Collateral  securing a Bond Series issued by the related
                    Trust in excess of amounts necessary to pay holders of Bonds
                    ("Bondholders")   of  such  Bond  Series;   (III)  does  not
                    constitute a claim  against the Depositor to the extent that
                    funds are  insufficient to pay such  indebtedness;  and (IV)
                    does not result in a reduction,  withdrawal or qualifying of
                    the rating or ratings then assigned to the Bonds of any Bond
                    Series  issued  by  the  Trust  issuing  such   subordinated
                    indebtedness,  as  confirmed  in writing  by the  nationally
                    recognized statistical rating agency or agencies rating such
                    Bond Series;

               (E)  (I) to establish  one or more Trusts to engage in any one or
                    more of the activities  described in (A) and (D) above, each
                    of which  Trusts  and any  Trust  formed to engage in one or
                    more of the activities described in (C) above may deliver to
                    the   Depositor    Certificates    ("Trust    Certificates")
                    representing  the  ownership  interest in the assets of such
                    Trust, (II) to acquire,  own, hold, sell, transfer,  assign,
                    pledge,  finance,  and otherwise deal with any or all of the
                    Trust  Certificates  in any Trust  that it  establishes  and
                    (III) to act as settlor or  depositor  of such Trusts and to
                    invest in or sell Trust Certificates; and

               (F)  to engage in any other acts and  activities  and to exercise
                    any powers  permitted to corporations  under the laws of the
                    State of  Delaware  which are  incidental  to, or  connected
                    with, the foregoing,  and necessary,  suitable or convenient
                    to accomplish any of the foregoing;

              Capitalized  terms defined in this clause (v) shall apply only to
              such clause.

       (vi)   There  is no  action,  suit  or  proceeding  pending  against  the
              Depositor  in any  court or by or before  any  other  governmental
              agency or  instrumentality  which would  materially  and adversely
              affect the ability of the  Depositor to carry out its  obligations
              under this Agreement; and

       (vii)  The Trustee,  if not the owner of the related  Mortgage Loan, will
              have a valid and perfected  security interest of first priority in
              each of the Mortgage Loans and any proceeds thereof.

     (b) The  Depositor  hereby  represents  and  warrants  with respect to each
Mortgage Loan that:

       (i)    Immediately  prior to the transfer and  assignment to the Trustee:
              (a) the Note and the Mortgage were not subject to an assignment or
              pledge (except as described in Section 2.01(b) with respect to the
              Westin  Casuarina  Resort  Loan),  and (b) the  Depositor had good
              title to,  and was the sole owner of,  the  Mortgage  Loan and had
              full right to transfer and sell the  Mortgage  Loan to the Trustee
              free and clear of any encumbrance,  equity, lien, pledge,  charge,
              claim or security interest;

       (ii)   The Depositor is transferring such Mortgage Loan free and clear of
              any and all liens,  pledges,  charges or security interests of any
              nature encumbering such Mortgage Loan;

       (iii)  Except as described in Section  2.01(b) with respect to the Westin
              Casuarina   Resort  Loan,  the  related   Assignment  of  Mortgage
              constitutes  the  legal,  valid  and  binding  assignment  of such
              Mortgage  from  the  Depositor  to the  Trustee,  and any  related
              Reassignment   of   Assignment   of  Leases,   Rents  and  Profits
              constitutes  the  legal,  valid and  binding  assignment  from the
              Depositor  to the  Trustee,  and the  Westin  Casuarina  Co-Lender
              Agreement  and  assignment   thereof  to  the  Trustee  hereunder,
              constitutes the legal, valid and binding obligation of the parties
              thereto;

       (iv)   No claims have been made by the Depositor under the lender's title
              insurance  policy,  and  the  Depositor  has not  done,  by act or
              omission,  anything  which  would  impair  the  coverage  of  such
              lender's title insurance policy;

       (v)    All of the  representations  and  warranties  of the Mortgage Loan
              Sellers   contained  in  the  Mortgage   Loan  Purchase  and  Sale
              Agreements are true and correct as of the Cut-off Date;

       (vi)   (1) Such Mortgage  Loan is directly  secured by a Mortgage on Real
              Property,  and (2) either (i) substantially all of the proceeds of
              such  Mortgage  Loan were used to acquire or improve or protect an
              interest in real property that, at the  origination  date, was the
              only  security  for the  Mortgage  Loan (in the case of a Mortgage
              Loan that has not been  modified  in a manner that  constituted  a
              deemed  exchange under Section 1001 of the Code at a time when the
              Mortgage  Loan was not in default or default with respect  thereto
              was not reasonably  foreseeable)  or (ii) the fair market value of
              such  real  property  was at least  equal to 80% of the  principal
              amount  of the  Mortgage  Loan  (a)  at  origination  (or,  if the
              Mortgage  Loan has been  modified in a manner that  constituted  a
              deemed  exchange under Section 1001 of the Code at a time when the
              Mortgage  Loan was not in default or default with respect  thereto
              was  not  reasonably  foreseeable,  the  date  of  the  last  such
              modification)  or (b) at  the  Closing  Date;  provided  that  for
              purposes of this  clause  (ii) the fair  market  value of the real
              property  interest  must first be reduced by (A) the amount of any
              lien on the real property  interest that is senior to the Mortgage
              Loan  (unless such senior lien also  secures a Mortgage  Loan,  in
              which  event  the  computation  described  in (a)  and (b) of this
              clause  (ii)  shall  be  made  on an  aggregate  basis)  and (B) a
              proportionate  amount  of any  lien  that is in  parity  with  the
              Mortgage Loan (unless such other lien secures a Mortgage Loan that
              is  cross-collateralized  with such Mortgage  Loan, in which event
              the computation described in (a) and (b) of this clause (ii) shall
              be made on an aggregate basis); and

       (vii)  The  information  set forth with respect to such  Mortgage Loan on
              the  Mortgage  Loan  Schedule is true and correct in all  material
              respects  as of the dates  respecting  which such  information  is
              given, or if no date is specified, as of the Cut-off Date.

     (c) It is understood and agreed that the representations and warranties set
forth in this Section 2.03 shall  survive  delivery of the  respective  Mortgage
Files to the Trustee until the termination of this Agreement, and shall inure to
the benefit of the Certificateholders and the Servicer.

     (d) Upon discovery by the Custodian,  the Servicer, the Special Servicer or
the Trustee of a breach of the  representation and warranty set forth in Section
2.03(b)(vi) or that any Mortgage Loan otherwise  fails to constitute a Qualified
Mortgage,  such Person shall give prompt notice thereof to the Depositor and the
Depositor  shall correct such  condition or repurchase or cause the  responsible
Mortgage Loan Seller to repurchase  such Mortgage Loan at the  Repurchase  Price
within 90 days of discovery of such failure; it being understood and agreed that
none of such Persons has an obligation to conduct any investigation with respect
to such  matters.  It is  understood  and  agreed  that the  obligations  of the
Depositor  set forth in this  Section  2.03(d) to cure or  repurchase a Mortgage
Loan which fails to constitute a Qualified  Mortgage  shall be the sole remedies
available  to the  Trustee  against  the  Depositor  respecting  a  breach  of a
representation or warranty set forth in Section 2.03(b)(vi).

     (e) Upon discovery by the Custodian,  the Servicer, the Special Servicer or
the Trustee of a breach of any  representation  or warranty of the Mortgage Loan
Sellers in the Mortgage  Loan Purchase and Sale  Agreements  with respect to any
Mortgage Loan, or that any document required to be included in the Mortgage File
does not conform to the  requirements  of Section  2.01,  such Person shall give
prompt notice thereof to the appropriate  Mortgage Loan Seller and such Mortgage
Loan Seller shall,  to the extent such Mortgage Loan Seller is obligated to cure
or repurchase the related  Mortgage Loan under the terms of the related Mortgage
Loan Purchase and Sale  Agreement,  either cure such breach or  repurchase  said
Mortgage Loan at the Repurchase Price within 90 days of the receipt of notice of
the breach as provided in the related Mortgage Loan Purchase and Sale Agreement;
it being  understood  and agreed that none of the Custodian,  the Servicer,  the
Special Servicer, and the Trustee has an obligation to conduct any investigation
with respect to such matters (except,  in the case of the Mortgage Files, to the
extent provided in Section 2.01); provided, however, that in the event that such
breach is capable of being cured as  determined  by the  Servicer or the Special
Servicer,  as applicable,  but not within such 90 day period and the appropriate
Mortgage Loan Seller has commenced and is diligently proceeding with the cure of
such breach within such 90 day period (other than a breach that is also a breach
of Section 2.03(b)(vi) or 2.03(d)),  the appropriate  Mortgage Loan Seller shall
have an additional 90 days to complete such cure; provided,  further,  that with
respect to such  additional 90 day period the  appropriate  Mortgage Loan Seller
shall have  delivered an officer's  certificate  to the Trustee and the Servicer
setting  forth the reason such  breach is not capable of being cured  within the
initial 90 day period and what actions the  Mortgage  Loan Seller is pursuing in
connection  with the cure  thereof and  stating  that the  Mortgage  Loan Seller
anticipates  that such breach will be cured within the additional 90 day period;
and,  provided,  further,  the  Repurchase  Price shall include  interest on any
Advances  made in  respect  of the  related  Mortgage  Loan.  Any  out-of-pocket
expenses  incurred by the Servicer  pursuant to this Section 2.03(e),  and which
have not been  previously  reimbursed,  and  which  in the good  faith  business
judgment of the Servicer would not be ultimately  recoverable  under clause (iv)
of the  definition  of  Repurchase  Price shall  constitute  a Property  Advance
hereunder.

     (f) Upon receipt by the Servicer from the Depositor or appropriate Mortgage
Loan Seller of the  Repurchase  Price for the  repurchased  Mortgage  Loan,  the
Servicer shall deposit such amount in the Collection  Account,  and the Trustee,
pursuant to Section 3.11,  shall,  upon receipt of a certificate  of a Servicing
Officer certifying as to the receipt by the Servicer of the Repurchase Price and
the deposit of the Repurchase Price into the Collection Account pursuant to this
Section  2.03(f),  release  or  cause to be  released  to the  Depositor  or the
appropriate Mortgage Loan Seller the related Mortgage File and shall execute and
deliver  such  instruments  of  transfer  or  assignment,  in each case  without
recourse,  representation  or warranty,  as shall be prepared by the Servicer to
vest in the Depositor or the appropriate  Mortgage Loan Seller any Mortgage Loan
released  pursuant hereto,  and any rights of the Depositor in, to and under the
Mortgage  Loan  Purchase and Sale  Agreement as it related to such Mortgage Loan
that was initially  transferred  to the Trust Fund under  Section  2.01,  and if
applicable  any  rights  of NACC or  Depositor  in,  to and  under  the  related
Bloomfield  Purchase  Agreement  as it related to such  Mortgage  Loan that were
initially  transferred to the Trust Fund under Section 2.01, and the Trustee and
the Servicer shall have no further  responsibility  with regard to such Mortgage
File.

     (g) In the event  that any  Mortgage  Loan  Seller  incurs  any  expense in
connection  with curing a breach of a  representation  or  warranty  pursuant to
Section  2.03(e) which also  constitutes  a default  under the related  Mortgage
Loan,  such Mortgage  Loan Seller shall have a right,  subrogated to that of the
Trustee,  as successor to the mortgagee,  to recover the amount of such expenses
from the  related  Borrower.  The  Servicer  shall  use  reasonable  efforts  in
recovering,  or assisting  such  Mortgage  Loan Seller in  recovering,  from the
related  Borrower the amount of any such expenses.  Any  out-of-pocket  expenses
incurred by the Servicer  pursuant to this Section  2.03(g),  and which have not
been previously reimbursed, and which in the good faith business judgment of the
Servicer would not be ultimately recoverable under clause (iv) of the definition
of Repurchase Price shall constitute a Property Advance hereunder.

     (h) In the event that any  litigation  is  commenced  which  alleges  facts
which, in the judgment of the Depositor, could constitute a breach of any of the
Depositor's  representations  and warranties relating to the Mortgage Loans, the
Depositor hereby reserves the right to conduct the defense of such litigation at
its expense.

     (i) If for any reason the Mortgage Loan Sellers or the  Depositor  fails to
fulfill its  obligations  under this  Section  2.03 with respect to any Mortgage
Loan, the Servicer or Special Servicer shall use reasonable efforts in enforcing
any obligation of the Originator to cure or repurchase  such Mortgage Loan under
the  terms of the  related  Originator  Purchase  Agreement.  Any  out-of-pocket
expenses incurred by the Servicer or Special Servicer,  as applicable,  pursuant
to this Section  2.03(i),  and which have not been  previously  reimbursed,  and
which  in the  good  faith  business  judgment  of  the  Servicer  would  not be
ultimately  recoverable  under clause (iv) of the definition of Repurchase Price
shall constitute a Property Advance hereunder.

     (j) The Depositor additionally represents, warrants and covenants that:

       (i)    The  Depositor  will at all times  maintain  its  valid  corporate
              existence  in good  standing  under  the laws of the  state of its
              incorporation.  The  Depositor  has  otherwise  complied  and will
              comply  in  all  respects  with  the  laws  of  the  state  of its
              incorporation,  and  with  all  other  laws,  federal,  state,  or
              otherwise,  insofar as they are related to its separate  corporate
              existence,   and  it  will   observe   all   requisite   corporate
              formalities.

       (ii)   Although all directors and officers of the  Depositor,  except any
              director who is Independent, are directors, officers, or employees
              of NACC and/or Nomura Securities International, Inc. ("NSI"), such
              persons have not directly received, and will not directly receive,
              any  remuneration  from the  Depositor for serving as directors or
              officers of the  Depositor.  The  Depositor  is charged and pays a
              fair estimate,  adjusted every six months,  of payroll and related
              expenses  for  work  and  services  performed  by  the  directors,
              officers,  and employees of NACC or NSI for services  performed as
              directors or officers of the Depositor. The officers and directors
              of the Depositor,  when acting in such  capacity,  act in the best
              interests of the Depositor, consistent with their fiduciary duties
              as directors  and officers of such  corporation.  The Depositor is
              not  obligated  to  pay  or  distribute  to  NACC  or  any  of its
              Affiliates,  by dividend or  otherwise,  any portion of any of its
              profits or its other assets. The Depositor's profits, if any, may,
              at the  discretion  of the  Depositor's  Board  of  Directors  and
              subject to  applicable  law,  be  transferred  by  dividend to the
              Depositor's shareholder(s), which is presently NACC.

       (iii)  The Depositor  maintains its business in separately  allocated and
              identifiable  office space within the offices of its Affiliates in
              New York City. The  Depositor's  presence at such offices is noted
              in the building  directory and on other signs.  As set forth above
              in connection with payroll expenses,  the Depositor is charged and
              pays rent in an amount  corresponding to the portion of the office
              space allocated to the Depositor.

       (iv)   The Depositor has a telephone  number different from any telephone
              numbers  of NACC and the  Financing  Trust and NSI or any of their
              Affiliates.  The Depositor uses its own stationery  that indicates
              its  separate  telephone  number and  identifies  it as a separate
              corporate entity.

       (v)    The Depositor shall not fail to correct any known misunderstanding
              regarding the separate  identity of the  Depositor,  or purport to
              operate as an  integrated,  single  economic  unit with any of its
              Affiliates in dealing with any  unaffiliated  entity.  Neither the
              Mortgage Loan Sellers nor NSI finance the  Depositor's  operations
              or guarantees the Depositor's obligations,  and the Depositor does
              not finance the  operations  or guarantee the  obligations  of the
              Mortgage  Loan Sellers or NSI;  provided,  however,  that NACC has
              made  capital  contributions  to  the  Depositor,   and  may  make
              additional  capital  contributions from time to time in connection
              with the  expansion of the  Depositor's  business or to enable the
              Depositor to invest in  privately-offered  Certificates.  However,
              NACC  does  not pay or  subsidize  any of the  Depositor's  normal
              operating expenses.  The Depositor will pay from its own funds its
              operating  expenses  and  liabilities,  including  legal  fees and
              expenses,  or will  reimburse the Mortgage Loan Sellers or NSI for
              any such expenses or liabilities paid by the Mortgage Loan Sellers
              or NSI on the Depositor's  behalf.  To facilitate the registration
              process,  NACC and/or NSI has  advanced  and may  advance  certain
              expenses  of  the  Depositor   associated  with  the  registration
              process. The Depositor has repaid or will repay to NACC and/or NSI
              these  expenses  on an  allocable  basis  out of the  proceeds  of
              mortgage  pass-through  transactions.  Neither the  Mortgage  Loan
              Sellers nor NSI have funded or will fund the Depositor's operating
              expenses.  The assets or  creditworthiness  of the  Mortgage  Loan
              Sellers,  NSI or any of their  Affiliates  are not held out by the
              Depositor as being  available  for the payment of the  Depositor's
              liabilities or obligations,  and the assets or creditworthiness of
              the Depositor are not held out by the Depositor as being available
              for the payment of the  liabilities  of the Mortgage Loan Sellers,
              NSI or any of  their  Affiliates  other  than the  Depositor.  The
              assets or  creditworthiness  of the  Depositor are not held out by
              the  Mortgage  Loan  Sellers  or  NSI,  to  the  knowledge  of the
              Depositor,  and the  Depositor  will not permit that its assets or
              creditworthiness  will be held out by the Mortgage Loan Sellers or
              NSI,  as being  available  for the payment of the  liabilities  or
              obligations  of the  Mortgage  Loan  Sellers,  NSI or any of their
              Affiliates.  The assets or  creditworthiness  of the Mortgage Loan
              Sellers,  NSI or any of their  Affiliates  are not held out by the
              Mortgage Loan Sellers or NSI, to the  knowledge of the  Depositor,
              and  the   Depositor   will  not   permit   that  the   assets  or
              creditworthiness  of the Mortgage Loan Sellers or NSI will be held
              out by the Mortgage  Loan Sellers or NSI, as being  available  for
              the payment of the  liabilities of the Depositor.  The Depositor's
              assets are now, and are  expected in the future to be,  sufficient
              to pay the Depositor's  ongoing  expenses as they are incurred and
              to discharge all of the Depositor's  liabilities in the event that
              the business of the Depositor is required to be liquidated.

       (vi)   The separate  corporate  existence of the Depositor is not used by
              either the Depositor,  or, to the knowledge of the  Depositor,  by
              the  Mortgage  Loan  Sellers or NSI,  and the  Depositor  will not
              permit that its separate  corporate  existence will be used by the
              Mortgage Loan Sellers or NSI, to abuse  creditors or to perpetrate
              a fraud, injury, or injustice on creditors.

       (vii)  The  Depositor's   existence  is  not  dependent  on  it  being  a
              subsidiary  of NACC or an Affiliate of NSI and it is expected that
              the  Depositor  would be able to maintain its business and affairs
              even if it were not a  subsidiary  of NACC or an Affiliate of NSI.
              To  the  knowledge  of  the  Depositor,  NACC's  existence  is not
              dependent on the Depositor being its subsidiary and it is expected
              that NACC would be able to maintain  its business and affairs even
              if the Depositor were not its subsidiary.  To the knowledge of the
              Depositor,  the Mortgage Loan Sellers'  existence is not dependent
              on the Depositor being their Affiliate and it is expected that NSI
              would be able to maintain  its  business  and affairs  even if the
              Depositor  were not its  Affiliate.  The  Depositor  conducts  its
              business  separate  and apart from the  business  conducted by any
              other person or entity.

       (viii) The Depositor  maintains corporate records distinct and separately
              identifiable  from the  corporate  records  of the  Mortgage  Loan
              Sellers,  NSI  and any  other  person  or  entity.  The  Depositor
              prepares  monthly   financial   records  distinct  and  separately
              identifiable  from the  financial  records  of the  Mortgage  Loan
              Sellers,  NSI or any of their  Affiliates.  These  statements  and
              reports are prepared and  maintained in accordance  with generally
              accepted accounting principles,  susceptible to audit and audited,
              at least  annually,  in connection with the audit of the Depositor
              and its Affiliates on a consolidated  basis by independent  public
              accountants  in  accordance  with  generally   accepted   auditing
              standards.  Such consolidated financial statements will henceforth
              indicate  that the assets of the  Depositor  are not  available to
              satisfy the creditors of any entity other than the Depositor.  The
              Depositor keeps its funds separate and apart from the funds of the
              Mortgage Loan Sellers,  NSI and any of their  Affiliates,  and its
              other assets are separately  identifiable and distinguishable from
              the  assets of the  Mortgage  Loan  Sellers,  NSI and any of their
              Affiliates.

       (ix)   The  Depositor  acts solely in its own  corporate  name and solely
              through  its duly  authorized  officers or agents.  The  Depositor
              complies with the provisions of its  Certificate of  Incorporation
              and  its  By-Laws  and  complies  in  all  material  respects,  in
              connection with its separate existence, with the laws of the state
              in which it is incorporated. In addition, the sole shareholder and
              the Board of Directors of the Depositor  hold all such meetings or
              execute  consents  necessary to authorize  corporate action by the
              Depositor, and the Depositor maintains appropriate minutes of such
              meetings  or  records  of  its  written  consents.  The  Depositor
              observes all requisite corporate formalities.

       (x)    All transactions  between the Mortgage Loan Sellers or NSI (or any
              of their Affiliates),  on the one hand, and the Depositor,  on the
              other,  are,  and will be, duly  authorized  and  documented,  and
              recorded  accurately in the  appropriate  books and records of the
              Depositor,   and  to  the  knowledge  of  the  Depositor,  in  the
              appropriate books and records of the Mortgage Loan Sellers or NSI,
              if  the  Mortgage   Loan  Sellers  or  NSI  is  a  party  to  such
              transaction.  All  such  transactions  are  fair  to  each  party,
              constitute  exchanges for fair  consideration  and for  reasonably
              equivalent  value,  and are made in good  faith  and  without  any
              actual  intent  to  hinder,  delay,  or  defraud  creditors.   The
              Depositor  will not  take any  action,  and  will  not  engage  in
              transactions  with the Mortgage Loan Sellers,  NSI or any of their
              Affiliates  unless the respective Boards of Directors or officers,
              as appropriate,  of the Depositor and the Mortgage Loan Sellers or
              NSI, if the Mortgage Loan Sellers or NSI, respectively, is a party
              to such transaction,  determine in a reasonable  fashion that such
              actions or transactions  are in their  respective  companies' best
              interests.

       (xi)   The Depositor  intends the transfer of the Mortgage Loans from the
              Mortgage  Loan Sellers to the  Depositor  pursuant to the Mortgage
              Loan  Purchase  and Sale  Agreements  to be a sale of the Mortgage
              Loans.  The Depositor  intends the transfer of the Mortgage  Loans
              from the Depositor to the Trustee pursuant to this Agreement,  and
              the  transfer  of  Certificates   to  NSI  (all   Certificates  so
              transferred,  the  "NSI  Certificates"),  to  be  sales  from  the
              Depositor to the Trustee (the  "Depositor/Trustee  Transfer")  and
              from  the  Depositor  to  NSI  (the   "Depositor/NSI   Transfer"),
              respectively.  The  Depositor  will  treat  the  transfer  of  the
              Mortgage   Loans,   the   Depositor/Trustee   Transfer   and   the
              Depositor/NSI  Transfer as sales for  accounting and tax purposes.
              The  purchase   prices  for  the   Mortgage   Loans  and  the  NSI
              Certificates   reflect  the  good  faith   determinations  of  the
              Depositor of the fair market  value of the Mortgage  Loans and the
              NSI Certificates,  respectively,  and are equal to the prices that
              the  Depositor  believes  would be paid in  sales of the  Mortgage
              Loans or the NSI Certificates between non-affiliated  entities. No
              provision  exists  whereby  such  consideration  may  be  modified
              subsequent  to closing,  and the  Depositor  has no  obligation to
              repay such  consideration,  or interest thereon, to the Trustee or
              NSI, as applicable.  The Depositor will receive the  consideration
              for the NSI Certificates.

       (xii)  The Depositor  irrevocably  transfers and  relinquishes all rights
              with respect to the Mortgage Loans and, specifically, has no right
              to sell,  pledge  or  otherwise  dispose  of the  Mortgage  Loans.
              Subject  to the terms of this  Agreement,  the  Trustee is free to
              deal with the  Mortgage  Loans as  trustee  of trust  property  on
              behalf of the  Certificateholders.  The  Depositor  transfers  the
              Mortgage  Loans without  recourse and has no obligation to deliver
              other  property to the Trustee  either in  substitution  for or in
              addition  to the  Mortgage  Loans in the event of a credit loss or
              decline in value of the Mortgage Loans. The Depositor has no right
              to transfer the Mortgage Loans back to the Mortgage Loan Sellers.

       (xiii) The  Depositor  has  not   transferred   the  Mortgage   Loans  in
              contemplation of insolvency or with a design to prefer one or more
              creditors  to the  exclusion in whole or in part of others or with
              an actual intent to hinder, delay or defraud any of its creditors.

       (xiv)  The  assets of the  Depositor  are now,  and are  expected  in the
              future to be,  sufficient to pay the ongoing business  expenses of
              the  Depositor as they are  incurred  and to discharge  all of its
              liabilities  in the event that the  business of the  Depositor  is
              required to be liquidated.

       (xv)   The property  remaining in the hands of the Depositor after giving
              effect to the  Transfers  is not an  unreasonably  small amount of
              capital for the business in which the Depositor is engaged.

     SECTION 2.04.  Representations,  Warranties  and Covenants of the Servicer,
                    Special Servicer and Trustee.

     (a) The Servicer,  as Servicer,  hereby represents,  warrants and covenants
that as of the Closing Date or as of such date specifically provided herein:

       (i)    The Servicer is a limited  partnership,  duly  organized,  validly
              existing  and in good  standing  under  the  laws of the  State of
              Delaware and has all material  licenses  necessary to carry on its
              business as now being  conducted or is in compliance with the laws
              of each state  (within the United  States of America) in which any
              Mortgaged  Property is located to the extent  necessary  to comply
              with its duties and  responsibilities  hereunder  with  respect to
              each Mortgage Loan in accordance with the terms of this Agreement;
              to the best  knowledge  of the  Servicer,  it is not  required  to
              become  licensed  for such  purposes  with  respect  to the Cayman
              Islands,  but the Servicer shall endeavor to become so licensed if
              so required;

       (ii)   The Servicer has the full partnership  power,  authority and legal
              right to execute  and  deliver  this  Agreement  and to perform in
              accordance herewith;  the execution and delivery of this Agreement
              by the Servicer and its  performance and compliance with the terms
              of this Agreement  will not violate the Servicer's  certificate of
              limited  partnership  or  partnership  agreement,  or constitute a
              default (or an event which, with notice or lapse of time, or both,
              would constitute a default) under, or result in the breach of, any
              material  contract,  agreement  or other  instrument  to which the
              Servicer is a party or which may be  applicable to the Servicer or
              any of its assets;

       (iii)  This Agreement has been duly and validly authorized,  executed and
              delivered  by  the  Servicer  and,  assuming  due   authorization,
              execution and delivery by the other parties hereto,  constitutes a
              legal, valid and binding  obligation of the Servicer,  enforceable
              against it in accordance with the terms of this Agreement,  except
              as such  enforcement  may be  limited by  bankruptcy,  insolvency,
              reorganization,  liquidation,  receivership,  moratorium  or other
              laws relating to or affecting  creditors' rights generally,  or by
              general   principles  of  equity   (regardless   of  whether  such
              enforceability is considered in a proceeding in equity or at law),
              and  all  requisite  partnership  action  has  been  taken  by the
              Servicer to make this  Agreement and all  agreements  contemplated
              hereby  valid and binding  upon the  Servicer in  accordance  with
              their terms;

       (iv)   The  Servicer  is not in  violation  of,  and  the  execution  and
              delivery of this Agreement by the Servicer and its performance and
              compliance  with the terms of this Agreement will not constitute a
              violation  with  respect  to,  any  order or  decree  of any court
              binding on the Servicer or any order or regulation of any federal,
              state,  municipal or governmental agency having  jurisdiction,  or
              result  in the  creation  or  imposition  of any  lien,  charge or
              encumbrance which, in any such event, would have consequences that
              would materially and adversely affect the condition  (financial or
              otherwise)  or  operation  of the  Servicer or its  properties  or
              impair the  ability  of the Trust Fund to realize on the  Mortgage
              Loans;

       (v)    There is no action, suit,  proceeding or investigation  pending or
              threatened against the Servicer which,  either in any one instance
              or in the aggregate,  would result in any material  adverse change
              in the business,  operations,  financial condition,  properties or
              assets  of the  Servicer,  or in any  material  impairment  of the
              right, or would, if adversely  determined,  materially  impair the
              ability of the Servicer, to carry on its business substantially as
              now  conducted,  or in any  material  liability on the part of the
              Servicer,  or which would draw into  question the validity of this
              Agreement  or the  Mortgage  Loans or of any action taken or to be
              taken  in  connection   with  the   obligations  of  the  Servicer
              contemplated herein, or which would be likely to impair materially
              the  ability of the  Servicer  to perform  under the terms of this
              Agreement;

       (vi)   No consent,  approval,  authorization or order of, or registration
              or filing with, or notice to any court or  governmental  agency or
              body, is required for the execution,  delivery and  performance by
              the Servicer of or compliance by the Servicer with this Agreement,
              or if  required,  such  approval  has been  obtained  prior to the
              Cut-off Date; and

       (vii)  any sub-servicing agreement in effect on or after the Closing Date
              between  the  Sub-Servicer  and  the  Servicer  provides  or  will
              provide,  among other  things,  that the  Servicer may at its sole
              option,  terminate any rights the Sub-Servicer may have thereunder
              (without  cost or  obligation  to the Trust Fund or the  Servicer)
              with  respect  to any or all of the  Mortgage  Loans if any of the
              Rating  Agencies  (i) reduces  the rating  assigned to one or more
              Classes of  Certificates as a result of the  sub-servicing  of the
              Mortgage Loans by the  Sub-Servicer or (ii) advise the Servicer or
              the  Trustee  that it will  cause a  qualification,  downgrade  or
              withdrawal for such rating due to continued  sub-servicing  by the
              Sub-Servicer.

     (b) The Special Servicer, as Special Servicer, hereby represents,  warrants
and  covenants  that as of the  Closing  Date or as of  such  date  specifically
provided herein:

       (i)    The Special  Servicer is a limited  partnership,  duly  organized,
              validly  existing and in good standing under the laws of the State
              of  Maryland  and has  all  licenses  necessary  to  carry  on its
              business as now being  conducted or will be in compliance with the
              laws of each state  (within the United States of America) in which
              any  Mortgaged  Property  is located to the  extent  necessary  to
              comply with its duties and responsibilities hereunder with respect
              to each  Mortgage  Loan  in  accordance  with  the  terms  of this
              Agreement;

       (ii)   The Special Servicer has the full power, authority and legal right
              to execute and deliver this Agreement and to perform in accordance
              herewith;  the  execution  and  delivery of this  Agreement by the
              Special Servicer and its performance and compliance with the terms
              of  this  Agreement  will  not  violate  the  Special   Servicer's
              partnership  agreement and  certificate of limited  partnership or
              constitute a default (or an event  which,  with notice or lapse of
              time, or both, would constitute a default) under, or result in the
              breach of, any material contract, agreement or other instrument to
              which the Special  Servicer is a party or which may be  applicable
              to the Special Servicer or any of its assets;

       (iii)  This Agreement has been duly and validly authorized,  executed and
              delivered by the Special Servicer and, assuming due authorization,
              execution and delivery by the other parties hereto,  constitutes a
              legal,  valid and  binding  obligation  of the  Special  Servicer,
              enforceable  against  it in  accordance  with  the  terms  of this
              Agreement,   except  as  such   enforcement   may  be  limited  by
              bankruptcy, insolvency, reorganization, liquidation, receivership,
              moratorium  or other  laws  relating  to or  affecting  creditors'
              rights generally,  or by general  principles of equity (regardless
              of whether such  enforceability  is  considered in a proceeding in
              equity or at law),  and all  requisite  corporate  action has been
              taken by the  Special  Servicer  to make  this  Agreement  and all
              agreements  contemplated hereby valid and binding upon the Special
              Servicer in accordance with their terms;

       (iv)   The Special Servicer is not in violation of, and the execution and
              delivery  of  this  Agreement  by the  Special  Servicer  and  its
              performance  and compliance  with the terms of this Agreement will
              not constitute a violation with respect to, any order or decree of
              any  court  binding  on  the  Special  Servicer  or any  order  or
              regulation of any federal, state, municipal or governmental agency
              having  jurisdiction,  or result in the creation or  imposition of
              any lien,  charge or encumbrance  which, in any such event,  would
              have  consequences  that would materially and adversely affect the
              condition  (financial  or  otherwise)  or operation of the Special
              Servicer or its properties or impair the ability of the Trust Fund
              to realize on the Mortgage Loans;

       (v)    There is no action, suit,  proceeding or investigation  pending or
              threatened  against the Special Servicer which,  either in any one
              instance or in the aggregate, would result in any material adverse
              change  in  the   business,   operations,   financial   condition,
              properties or assets of the Special  Servicer,  or in any material
              impairment  of the  right,  or  would,  if  adversely  determined,
              materially impair the ability of the Special Servicer, to carry on
              its business  substantially  as now conducted,  or in any material
              liability on the part of the Special Servicer, or which would draw
              into question the validity of this Agreement or the Mortgage Loans
              or of any  action  taken  or to be taken  in  connection  with the
              obligations of the Special Servicer  contemplated herein, or which
              would be likely to impair  materially  the  ability of the Special
              Servicer to perform under the terms of this Agreement; and

       (vi)   No consent,  approval,  authorization or order of, or registration
              or filing with, or notice to any court or  governmental  agency or
              body, is required for the execution,  delivery and  performance by
              the Special Servicer of or compliance by the Special Servicer with
              this  Agreement,  or if required,  such approval has been obtained
              prior to the Cut-off Date.

     (c) It is understood and agreed that the representations and warranties set
forth in this Section shall survive delivery of the respective Mortgage Files to
the Trustee or the Custodian on behalf of the Trustee until the  termination  of
this Agreement, and shall inure to the benefit of the Trustee, the Depositor and
the  Servicer or Special  Servicer,  as the case may be. Upon  discovery  by the
Depositor,  the  Servicer,  Special  Servicer  or a  Responsible  Officer of the
Trustee (or upon written notice thereof from any  Certificateholder) of a breach
of any of the  representations  and  warranties  set forth in this Section which
materially and adversely  affects the interests of the  Certificateholders,  the
Servicer,  the Special  Servicer or the Trustee in any Mortgage  Loan, the party
discovering  such breach shall give prompt  written  notice to the other parties
hereto and the Mortgage Loan Sellers.

     (d) The Trustee hereby represents and warrants that as of the Closing Date:

       (i)    The Trustee is a nationally chartered bank duly organized, validly
              existing, and in good standing under the laws of the United States
              and  has  full  power,  authority  and  legal  right  to  own  its
              properties and conduct its business as presently  conducted and to
              execute, deliver and perform the terms of this Agreement.

       (ii)   This Agreement has been duly authorized, executed and delivered by
              the  Trustee  and,  assuming  due  authorization,   execution  and
              delivery by the other parties hereto,  constitutes a legal,  valid
              and  binding  instrument   enforceable   against  the  Trustee  in
              accordance  with its  terms,  except  as such  enforcement  may be
              limited by bankruptcy, insolvency, reorganization or other similar
              laws affecting the enforcement of creditors' rights in general and
              by  general   equity   principles   (regardless  of  whether  such
              enforcement is considered in a proceeding in equity or at law).

       (iii)  Neither  the  execution  and  delivery  of this  Agreement  by the
              Trustee nor the  consummation  by the Trustee of the  transactions
              herein contemplated to be performed by the Trustee, nor compliance
              by the Trustee with the provisions  hereof,  will conflict with or
              result in a breach of, or constitute a default  under,  any of the
              provisions of any  applicable  law (subject to the  appointment in
              accordance  with such applicable law of any co-trustee or separate
              trustee required pursuant to this Agreement),  governmental  rule,
              regulation,  judgment,  decree or order  binding on the Trustee or
              its properties or the  organizational  documents of the Trustee or
              the terms of any material  agreement,  instrument  or indenture to
              which the Trustee is a party or by which it is bound.

     SECTION  2.05.   Execution  and  Delivery  of  Certificates;   Issuance  of
                      Lower-Tier Regular Interests.

     The Trustee acknowledges the assignment to it of the Mortgage Loans and the
delivery of the Mortgage  Files to the  Custodian  (to the extent the  documents
constituting  the  Mortgage  Files are  actually  delivered  to the  Custodian),
subject to the  provisions  of Section 2.01 and Section  2.02 and,  concurrently
with such delivery, (i) acknowledges the issuance of and hereby declares that it
holds the Lower-Tier Regular Interests on behalf of the Upper-Tier REMIC and the
Holders of the Regular  Certificates  and the Class R Certificates  and (ii) has

portion"  of the  interest  payments  on the Class  A-1A-L  Interest  within the
meaning  of  Treasury  Regulations  Section   1.860G-1(a)(2).   The  Class  PS-1

Class of the Lower-Tier Regular Interests is equal to the Certificate Balance of
the Related Certificates. The interest rate for each Class of Lower-Tier Regular
Interests  is a per  annum  rate  equal to the  Weighted  Average  Net  Mortgage
Pass-Through Rate.

interests in the Default  Interest subject to the liability of the Trust Fund to
pay Advance Interest Amounts.  The Class V-2 Certificates  represent  beneficial
pro rata undivided interests in the Excess Interest. The Class V-1 and Class V-2
Certificates  do not  represent  regular  or  residual  interests  in either the
Upper-Tier REMIC or the Lower-Tier REMIC.

     The Servicer's or Special Servicer's liability for actions and omissions in
its capacity as Servicer or Special  Servicer,  as the case may be, hereunder is
limited as provided herein (including,  without limitation,  pursuant to Section
6.03  hereof).  To the extent  consistent  with the foregoing and subject to any
express  limitations  set forth in this  Agreement,  the  Servicer  and  Special
Servicer  shall seek to maximize the timely and  complete  recovery of principal
and interest on the Notes;  provided,  however,  that nothing  herein  contained
shall be construed as an express or implied guarantee by the Servicer or Special
Servicer  of the  collectability  of the  Mortgage  Loans.  Subject  only to the
Servicing Standard,  the Servicer and Special Servicer shall have full power and
authority,  acting alone or through  sub-servicers  (subject to paragraph (c) of
this  Section 3.01 and to Section  3.02),  to do or cause to be done any and all
things in connection  with such servicing and  administration  which it may deem
consistent with the Servicing Standard and, in its reasonable  judgment,  in the
best interests of the Certificateholders,  including,  without limitation,  with
respect to each Mortgage Loan, to prepare, execute and deliver, on behalf of the
Certificateholders  and the  Trustee or any of them:  (i) any and all  financing
statements, continuation statements and other documents or instruments necessary
to maintain the lien on each  Mortgaged  Property and related  collateral;  (ii)
subject to Sections 3.09, 3.10 and 3.30, any modifications, waivers, consents or
amendments to or with respect to any documents contained in the related Mortgage
File; and (iii) any and all instruments of satisfaction or  cancellation,  or of
partial or full release or discharge, and all other comparable instruments, with
respect to the Mortgage  Loans and the  Mortgaged  Properties.  The Servicer and
Special  Servicer  shall  provide to the  Borrowers  any reports  required to be
provided to them pursuant to the Mortgage  Loans.  Subject to Section 3.11,  the
Trustee  shall,  upon the receipt of a written  request of a Servicing  Officer,
execute and deliver to the Servicer and Special  Servicer any powers of attorney
and other documents  prepared by the Servicer and Special Servicer and necessary
or appropriate (as certified in such written request) to enable the Servicer and
Special  Servicer  to  carry  out  their  servicing  and  administrative  duties
hereunder.

     (b) Unless otherwise provided in the related Note, the Servicer shall apply
any partial  Principal  Prepayment  received on a Mortgage  Loan on a date other
than a Due Date to the  principal  balance of such  Mortgage  Loan as of the Due
Date  immediately  following  the  date of  receipt  of such  partial  Principal
Prepayment.  Unless  otherwise  provided in the related Note, the Servicer shall
apply any amounts  received on U.S.  Treasury  obligations  (which  shall not be
redeemed by the Servicer prior to the maturity thereof) in respect of a Mortgage
Loan  being  defeased  pursuant  to its terms to the  principal  balance  of and
interest on such  Mortgage  Loan as of the Due Date  immediately  following  the
receipt of such amounts.

     (c)  Each  of  the  Servicer  and  the  Special  Servicer  may  enter  into
sub-servicing  agreements  with  third  parties  with  respect  to  any  of  its
respective obligations hereunder, provided, that (i) any such agreement shall be
consistent with the provisions of this Agreement,  (ii) no sub-servicer retained
by the  Servicer  or the  Special  Servicer,  as  applicable,  shall  grant  any
modification,  waiver or amendment to any Mortgage  Loan without the approval of
the Servicer or the Special  Servicer,  as  applicable,  which approval shall be
given or withheld in accordance  with the procedures set forth in Sections 3.09,
3.10, 3.28 or 3.30 (or the definition of Minimum Defaulted Monthly Payment), and
(iii) such  agreement  shall be consistent  with the Servicing  Standard (to the
extent  consistent with this Agreement).  Any such  sub-servicing  agreement may
permit the  sub-servicer to delegate its duties to agents or  subcontractors  so
long  as  the  related   agreements   or   arrangements   with  such  agents  or
subcontractors are consistent with the provisions of this Section 3.01(c).

     Any  sub-servicing  agreement  entered  into by the Servicer or the Special
Servicer,  as  applicable,  other  than  the  subservicing  agreement  with  the
Sub-Servicer,  shall provide that it may be assumed or terminated by the Trustee
or the Servicer, respectively, if the Trustee or the Servicer, respectively, has
assumed the duties of the Servicer or the Special Servicer, respectively, or any
successor  Servicer  or  Special  Servicer,  as  applicable,   without  cost  or
obligation  to the  assuming or  terminating  party or the Trust Fund,  upon the
assumption  by such party of the  obligations  of the  Servicer  or the  Special
Servicer,  as  applicable,   pursuant  to  Section  7.02.   Notwithstanding  the
foregoing,  any  sub-servicing  agreement in effect on or after the Closing Date
between the Sub-Servicer and the Servicer provides or will provide,  among other
things,  that the  Servicer  may at its sole  option,  terminate  any rights the
Sub-Servicer  may have thereunder  (without cost or obligation to the Trust Fund
or the Servicer)  with respect to any or all of the Mortgage Loans if any of the
Rating  Agencies  (i)  reduces  the rating  assigned  to one or more  Classes of
Certificates  as a result  of the  sub-servicing  of the  Mortgage  Loans by the
Sub-Servicer  or (ii) advise the  Servicer  or the Trustee  that it will cause a
qualification,  downgrade  or  withdrawal  for  such  rating  due  to  continued
sub-servicing by the Sub-Servicer.

     Any  sub-servicing  agreement  entered into by the Servicer,  including any
sub-servicing agreement with the Sub-Servicer,  shall provide that, with respect
to any  Mortgage  Loan in which  an  Affiliate  of the  sub-servicer  holds  any
subordinate debt,  preferred equity  investment,  or mezzanine debt of a related
Borrower or its Affiliate, such sub-servicer may sub-service such Mortgage Loan;
provided,  however,  that the Servicer  shall make all decisions with respect to
the  administration  of any such Mortgage Loan  including,  without  limitation,
lease  approvals,  calculation  of and releases  from  reserves,  modifications,
waivers  and  amendments  of the  terms  thereof,  releases  of  collateral  and
transfers to special servicing.

     Any  sub-servicing  agreement,  and  any  other  transactions  or  services
relating to the Mortgage Loans involving a  sub-servicer,  shall be deemed to be
between  the  Servicer  or  the  Special  Servicer,  as  applicable,   and  such
sub-servicer alone, and the Trustee,  the Trust Fund and the  Certificateholders
shall  not  be  deemed  parties  thereto  and  shall  have  no  claims,  rights,
obligations,  duties or liabilities with respect to the sub-servicer,  except as
set forth in Section  3.01(d) and no provision  herein may be construed so as to
require the Trust Fund to indemnify any such sub-servicer.

     (d) If the Trustee or any successor Servicer assumes the obligations of the
Servicer,  or if the  Servicer or any  successor  Special  Servicer  assumes the
obligations  of the Special  Servicer,  in each case in accordance  with Section
7.02, the Trustee, the Servicer or such successor, as applicable,  to the extent
necessary to permit the Trustee, the Servicer or such successor,  as applicable,
to carry out the provisions of Section 7.02,  shall,  without act or deed on the
part of the Trustee, the Servicer or such successor,  as applicable,  succeed to
all of the rights and  obligations of the Servicer or the Special  Servicer,  as
applicable,  under any  sub-servicing  agreement entered into by the Servicer or
the Special Servicer, as applicable, pursuant to Section 3.01(c), subject to the
right of  termination by the Trustee or Servicer,  as  applicable,  set forth in
Section  3.01(c).  In such event,  the Trustee,  the  Servicer or the  successor
Servicer or the Special Servicer, as applicable, shall be deemed to have assumed
all of the Servicer's or the Special Servicer's interest, as applicable, therein
(but not any  liabilities  or obligations in respect of acts or omissions of the
Servicer  or  the  Special  Servicer,  as  applicable,   prior  to  such  deemed
assumption)  and to have  replaced  the  Servicer  or the Special  Servicer,  as
applicable,  as a party to such sub-servicing agreement to the same extent as if
such sub-servicing  agreement had been assigned to the Trustee,  the Servicer or
such successor  Servicer or successor  Special Servicer,  as applicable,  except
that the Servicer or the Special Servicer,  as applicable,  shall not thereby be
relieved of any liability or obligations under such sub-servicing agreement that
accrued prior to the  succession  of the Trustee,  the Servicer or the successor
Servicer or successor Special Servicer, as applicable.

     In the event that the Trustee,  the Servicer or any  successor  Servicer or
Special  Servicer,  as  applicable,  assumes the  servicing  obligations  of the
Servicer or the Special  Servicer,  as applicable,  upon request of the Trustee,
the Servicer or such successor Servicer or Special Servicer, as applicable,  the
Servicer or Special  Servicer shall at its own expense (except in the event that
the Servicer is terminated  pursuant to Section 6.04(c),  in which event, at the
expense of the  Certificateholders  effecting such  termination)  deliver to the
Trustee,  the  Servicer  or such  successor  Servicer  or Special  Servicer,  as
applicable,  all documents and records relating to any  sub-servicing  agreement
and the Mortgage  Loans then being  serviced  thereunder  and an  accounting  of
amounts  collected  and  held by it,  if any,  and will  otherwise  use its best
efforts  to effect the  orderly  and  efficient  transfer  of any  sub-servicing
agreement to the  Trustee,  the  Servicer or the  successor  Servicer or Special
Servicer, as applicable.

     SECTION 3.02. Liability of the Servicer.

     Notwithstanding any sub-servicing  agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Servicer or Special
Servicer and any Person acting as sub-servicer (or its agents or subcontractors)
or any reference to actions taken through any Person acting as  sub-servicer  or
otherwise,  the  Servicer  or Special  Servicer,  as  applicable,  shall  remain
obligated and  primarily  liable to the Trustee and  Certificateholders  for the
servicing  and  administering  of the  Mortgage  Loans  in  accordance  with the
provisions of this Agreement without  diminution of such obligation or liability
by virtue  of such  sub-servicing  agreements  or  arrangements  or by virtue of
indemnification  from the Depositor or any other Person  acting as  sub-servicer
(or its agents or  subcontractors)  to the same  extent and under the same terms
and conditions as if the Servicer or Special Servicer, as applicable, alone were
servicing and  administering  the Mortgage  Loans.  Each of the Servicer and the
Special  Servicer  shall  be  entitled  to  enter  into an  agreement  with  any
sub-servicer  providing for indemnification of the Servicer or Special Servicer,
as applicable,  by such  sub-servicer,  and nothing  contained in this Agreement
shall be deemed to limit or modify such  indemnification,  but no such agreement
for indemnification shall be deemed to limit or modify this Agreement.

     SECTION 3.03. Collection of Certain Mortgage Loan Payments.

     (a)  The  Servicer  or the  Special  Servicer,  as  applicable,  shall  use
reasonable  efforts  to  collect  all  payments  called  for under the terms and
provisions of the Mortgage Loans it is obligated to service hereunder, and shall
follow the Servicing Standard with respect to such collection  procedures.  With
respect to each Specially Serviced Mortgage Loan, the Special Servicer shall use
its  reasonable  efforts  to  collect  income  statements  and rent  rolls  from
Borrowers  as  required  by the Loan  Documents  and the terms  hereof and shall
provide  copies thereof to the Servicer as provided  herein.  The Servicer shall
provide at least six months'  notice to the Special  Servicer  and  Borrowers of
Balloon  Payments  coming due.  Consistent  with the foregoing,  the Servicer or
Special  Servicer,  as applicable,  may in its discretion waive any late payment
charge (but not any Default Interest) in connection with any delinquent  Monthly
Payment or Balloon  Payment with respect to any Mortgage Loan. In addition,  the
Servicer  shall be entitled to take such actions with respect to the  collection
of payments on the Mortgage  Loans as are  permitted or required  under  Section
3.28 hereof.

     (b) In the  event  that the  Servicer  or  Special  Servicer  receives,  or
receives  notice from the related  Borrower  that it will be  receiving,  Excess
Interest  in any  Collection  Period,  the  Servicer  or  Special  Servicer,  as
applicable, will promptly notify the Trustee.

     SECTION 3.04.  Collection of Taxes,  Assessments and Similar Items;  Escrow
                    Accounts.

     (a) With respect to each Mortgage Loan (other than any REO Mortgage  Loan),
the  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.  Except with respect
to the Westin  Casuarina  Resort Loan, from time to time, the Servicer shall (i)
obtain all bills for the payment of such items (including renewal premiums), and
(ii) effect payment of all such bills 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  Borrower  fails  to make  any such  payment  on a  timely  basis or
collections  from the Borrower are  insufficient to pay any such item before the
applicable  penalty or termination date, (or with respect to Mortgage Loans with
no Escrow Accounts for such purpose,  upon determining (using efforts consistent
with the  Servicing  Standard)  that the Borrower has not made such payment) the
Servicer shall advance the amount of any shortfall as a Property  Advance unless
the Servicer  determines in its good faith  business  judgment that such Advance
would  be  a  Nonrecoverable   Advance.   The  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 respecting  which such Advance was made or if such
Advance has become a Nonrecoverable  Advance, to the extent permitted by Section
3.06 of this  Agreement.  No costs  incurred by the  Servicer in  effecting  the
payment of taxes and  assessments  on the Mortgaged  Properties  shall,  for the
purpose of  calculating  distributions  to  Certificateholders,  be added to the
amount owing under the related Mortgage Loans, notwithstanding that the terms of
such Mortgage Loans so permit.

     (b) The 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, an "Escrow Account") into which
all  Escrow  Payments  shall be  deposited  within  one (1)  Business  Day after
receipt.  The Servicer  shall also deposit into each Escrow  Account any amounts
representing losses on Permitted Investments pursuant to Section 3.07(b) 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.  Escrow Accounts shall be Eligible Accounts (except to the extent
the related  Mortgage  Loan  requires it to be held in an account that is not an
Eligible Account) and shall be entitled "AMRESCO Services, L.P., as Servicer, in
trust for LaSalle National Bank, as Trustee in trust for Holders of Nomura Asset
Securities Corporation,  Commercial Mortgage Pass-Through  Certificates,  Series
1998-D6, and Various Borrowers".  Withdrawals from an Escrow Account may be made
by the Servicer only:

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

       (ii)   to  transfer  funds to the  Collection  Account to  reimburse  the
              Servicer,  the Special Servicer,  the Trustee or the Fiscal Agent,
              as  applicable,  for any  Advance  (with  interest  thereon at the
              Advance Rate) 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 Escrow Account upon the termination of
              this Agreement;

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

       (vi)   to remove any funds  deposited in an Escrow  Account that were not
              required to be deposited therein.

     SECTION  3.05.  Collection  Account;   Distribution   Account;   Upper-Tier
                     Distribution Account; Default Interest Distribution
                     Account; and Excess Interest Distribution Account.

     (a) The Servicer shall establish and maintain the Collection Account in the
Trustee's name, for the benefit of the Certificateholders and the Trustee as the
Holder of the Lower-Tier  Regular  Interests.  The  Collection  Account shall be
established and maintained as an Eligible Account. The Servicer shall deposit or
cause  to be  deposited  in the  Collection  Account  within  one  Business  Day
following receipt the following payments and collections  received or made by it
on or with respect to the Mortgage Loans:

       (i)    all  payments  on  account of  principal  on the  Mortgage  Loans,
              including the principal component of Unscheduled Payments;

       (ii)   all payments on account of interest on the Mortgage  Loans and the
              interest  portion of all  Unscheduled  Payments and all Prepayment
              Premiums;

       (iii)  any amounts required to be deposited  pursuant to Section 3.07(b),
              in connection  with net losses  realized on Permitted  Investments
              with respect to funds held in the Collection Account;

       (iv)   all Net REO  Proceeds  withdrawn  from an REO Account  pursuant to
              Section 3.17(b) and all Net Insurance Proceeds and Net Liquidation
              Proceeds;

       (v)    any amounts received from Borrowers which represent  recoveries of
              Property  Protection  Expenses,  to the extent not permitted to be
              retained by the Servicer or Special Servicer as provided herein;

       (vi)   any other amounts  required by the provisions of this Agreement to
              be  deposited  into the  Collection  Account  by the  Servicer  or
              Special Servicer,  including, without limitation,  proceeds of any
              repurchase of a Mortgage Loan pursuant to Sections 2.03(d) and (e)
              hereof; and

       (vii)  any Servicer Prepayment Interest Shortfalls.

     The foregoing  requirements for deposits in the Collection Account shall be
exclusive,  it being understood and agreed that, without limiting the generality
of the  foregoing,  payments in the nature of late payment  charges  (subject to
Section 3.12 hereof),  Assumption  Fees,  loan  modification  fees, loan service
transaction fees, extension fees, demand fees, beneficiary statement charges and
similar  fees need not be deposited  in the  Collection  Account by the Servicer
and, to the extent  permitted  by  applicable  law,  the Servicer or the Special
Servicer,  as  applicable  in  accordance  with Section  3.12  hereof,  shall be
entitled  to retain  any such  charges  and fees  received  with  respect to the
Mortgage  Loans.  In the event  that the  Servicer  deposits  in the  Collection
Account any amount not  required  to be  deposited  therein,  it may at any time
withdraw such amount from the Collection  Account,  any provision  herein to the
contrary notwithstanding.

     (b) The Trustee shall  establish and maintain the  Distribution  Account in
the name of the Trustee, in trust for the benefit of the  Certificateholders and
the Trustee as the Holder of the Lower-Tier Regular Interests.  The Distribution
Account shall be established and maintained as an Eligible Account.

     (c) The Trustee shall  establish and maintain the  Upper-Tier  Distribution
Account  in  the  name  of  the  Trustee,  in  trust  for  the  benefit  of  the
Certificateholders. The Upper-Tier Distribution Account shall be established and
maintained as an Eligible Account.  With respect to each Distribution  Date, the
Trustee  shall  withdraw  from  the  Distribution  Account  and  deposit  in the
Upper-Tier  Distribution  Account on or before such date the amount of Available
Funds  (including  P&I Advances) and  Prepayment  Premiums to be  distributed in
respect of the Lower-Tier  Regular Interests  pursuant to Section 4.01(a)(i) and
Section 4.01(a)(ii) hereof on such date.  Notwithstanding anything herein to the
contrary, the Upper-Tier  Distribution Account may be maintained as a subaccount
of the Distribution  Account;  provided,  that accounts shall be maintained in a
manner sufficient to identify the deposits thereto and withdrawals therefrom.

     (d) Prior to the Servicer Remittance Date relating to any Collection Period
in which Default Interest is received,  the Trustee shall establish and maintain
the Default  Interest  Distribution  Account in the name of the Trustee in trust
for the  benefit  of the  Holders  of the Class V-1  Certificates.  The  Default
Interest Distribution Account shall be established and maintained as an Eligible
Account.  On or before the Servicer Remittance Date related to each Distribution
Date,  the  Servicer  shall  remit to the  Trustee  for  deposit in the  Default
Interest Distribution Account an amount equal to (i) the amount of the aggregate
Default Interest received during the preceding Collection Period, minus (ii) any
portions thereof withdrawn from the Collection  Account pursuant to clause (iii)
of Section  3.06 (such  amount,  if any,  the "Net  Default  Interest"  for such
Distribution Date).

     (e)  Prior to the  Servicer  Remittance  Date  relating  to any  Collection
Period,  in which Excess  Interest is received,  the Trustee shall establish and
maintain the Excess Interest  Distribution Account in the name of the Trustee in
trust for the benefit of the Holders of the Class V-2  Certificates.  The Excess
Interest Distribution Account shall be established and maintained as an Eligible

Distribution  Date,  the Servicer  shall remit to the Trustee for deposit in the
Excess  Interest  Distribution  Account an amount  equal to the Excess  Interest
received during the applicable Collection Period.  Following the distribution of
Excess Interest to Certificateholders on the first Distribution Date after which
there are no longer any Mortgage Loans outstanding which pursuant to their terms
could pay Excess  Interest,  the Trustee  shall  terminate  the Excess  Interest
Distribution Account.

     (f)  Funds  in  the  Collection  Account,  the  Distribution  Account,  the
Upper-Tier  Distribution  Account, the Default Interest Distribution Account and
the  Excess  Interest   Distribution   Account  may  be  invested  in  Permitted
Investments  in accordance  with the  provisions  of Section 3.07.  The Servicer
shall give written  notice to the Trustee of the location and account  number of
the  Collection  Account and shall  notify the  Trustee in writing  prior to any
subsequent change thereof.

     SECTION 3.06. Permitted Withdrawals from the Collection Account.

              and the Fiscal  Agent  shall have  priority  with  respect to such
              payment or  reimbursement),  the Servicer's right to reimburse any
              such Person  pursuant to this clause (ii) being limited to (x) any
              collections  on or in respect of the  particular  Mortgage Loan or

              Section  4.06(d),  or (z)  any  other  amounts  in the  Collection
              Account in the event that such  Advances or any  Advance  Interest
              Amount have been deemed to be  Nonrecoverable  Advances or are not
              reimbursed from recoveries in respect of the related Mortgage Loan
              or REO Property after a Final Recovery Determination;

       (iii)  (A) to pay to the  Servicer,  the Trustee or the Fiscal  Agent the

              Advance Interest Amounts not relating to any P&I Advances, in each
              case, first, out of any collected Default Interest  (provided that
              in the case of both (A) and (B),  the Trustee and the Fiscal Agent
              shall have priority with respect to such payments);

       (iv)   to pay on or before each Servicer  Remittance Date to the Servicer
              and the Special  Servicer,  as applicable,  as  compensation,  the

              3.07(b)  any  interest  or  investment   income  earned  on  funds
              deposited in the  Collection  Account (the  Servicer may rely on a
              certification  of the  Special  Servicer  as to amounts of Special
              Servicing  Compensation  to be  withdrawn  pursuant to this clause
              (iv));

       (v)    to remit  to the  Distribution  Account,  an  amount  equal to the
              Trustee Fee in respect of the  immediately  preceding  month to be
              paid from interest received on the related Mortgage Loan;

       (vi)   to pay on or before each Distribution  Date to the Depositor,  the
              appropriate Mortgage Loan Seller or other Originator,  as the case
              may be, with respect to each  Mortgage  Loan or REO Property  that
              has  previously  been  purchased or  repurchased by it pursuant to
              Section 2.03(d),  Section  2.03(e),  Section 3.18 or Section 9.01,
              all amounts received thereon during the related  Collection Period
              and  subsequent  to the date as of which the  amount  required  to
              effect such purchase or repurchase was determined;

       (vii)  to the extent not  reimbursed or paid pursuant to any other clause
              of this  Section  3.06,  to  reimburse  or pay the  Servicer,  the
              Trustee, the Special Servicer,  the Depositor or the Fiscal Agent,
              as  applicable,  for  unpaid  Servicing  Fees,  Special  Servicing
              Compensation  and  other  unpaid  items  incurred  by such  Person
              pursuant  to the  second  sentence  of  Section  3.07(c),  Section
              3.08(a) and (b), Section 3.10,  Section 3.12(e),  Section 3.17(a),
              (b) and (c),  Section  3.18(a),  the fourth  paragraph  of Section
              3.22,  Section 6.03,  Section 7.04,  Section  8.01(c)(v),  Section
              8.05(d) or Section 10.07, or any other provision of this Agreement
              pursuant  to which such Person is  entitled  to  reimbursement  or
              payment  from the Trust  Fund,  in each  case  only to the  extent
              reimbursable  under such Section,  it being acknowledged that this
              clause  (vii) shall not be deemed to modify the  substance  of any
              such Section,  including  the  provisions of such Section that set
              forth the  extent to which one of the  foregoing  Persons is or is
              not entitled to payment or reimbursement;

       (viii) to transfer  to the  Trustee for deposit in one or more  separate,
              non-interest bearing accounts any amount reasonably  determined by
              the Trustee to be necessary to pay any applicable  federal,  state
              or local taxes imposed on the  Upper-Tier  REMIC or the Lower-Tier
              REMIC  under the  circumstances  and to the  extent  described  in
              Section 4.05;

       (ix)   to withdraw any amount deposited into the Collection  Account that
              was not required to be deposited therein; and

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

     The Servicer  shall keep and maintain  separate  accounting,  on a Mortgage
Loan by Mortgage Loan basis,  for the purpose of justifying any withdrawal  from
the Collection Account pursuant to subclauses (i)-(vii) above.

     The  Servicer  shall pay to the  Trustee,  the Fiscal  Agent or the Special
Servicer  from the  Collection  Account  (to the  extent  permitted  by  clauses
(i)-(vii) above) amounts  permitted to be paid to the Trustee,  the Fiscal Agent
or the Special Servicer  therefrom,  promptly upon receipt of a certificate of a
Responsible  Officer of the Trustee or the Fiscal  Agent or a  certificate  of a
Servicing Officer,  as applicable,  describing the item and amount to which such
Person is entitled.  The Servicer may rely  conclusively on any such certificate
and shall have no duty to recalculate the amounts stated therein.

     The Trustee,  the Fiscal Agent, the Special Servicer and the 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  reimbursement  or
payment of the Servicing Compensation  (including investment income), or Trustee
Fees, Special Servicing Compensation,  Advances, Advance Interest Amounts, their
respective  expenses  hereunder  to the extent such fees and  expenses are to be
reimbursed or paid from amounts on deposit in the Collection Account pursuant to
this  Agreement  (and  to  have  such  amounts  paid  directly  to  third  party
contractors  for any  invoices  approved  by the  Trustee,  the  Servicer or the
Special Servicer,  as applicable) and any federal,  state or local taxes imposed
on either the Upper-Tier REMIC or Lower-Tier REMIC.

     SECTION  3.07.  Investment  of Funds  in the  Collection  Account,  the REO
                     Account,  the Lock-Box  Accounts,  the Cash  Collateral
                     Accounts, the Interest Reserve Account and the Reserve
                     Accounts.

     (a) The Servicer (or with respect to any REO Account, the Special Servicer,
or with respect to the Interest Reserve Account, NACC) may direct any depository
institution  maintaining the Collection Account,  any Borrower Accounts (subject
to the second  succeeding  sentence),  the Interest  Reserve Account and any REO
Account (each, for purposes of this Section 3.07, an "Investment  Account"),  to
invest the funds in such Investment Account in one or more Permitted Investments
that bear interest or are sold at a discount, and that mature, unless payable on
demand,  no later than the Business Day  preceding  the date on which such funds
are  required to be  withdrawn  from such  Investment  Account  pursuant to this
Agreement.  Any direction by the Servicer,  the Special  Servicer or by NACC, to
invest funds on deposit in an  Investment  Account shall be in writing and shall
certify that the requested investment is a Permitted Investment which matures at
or prior to the time required hereby or is payable on demand. In the case of any
Escrow Account,  Lock-Box  Account,  Cash Collateral  Account or Reserve Account
(the "Borrower  Accounts"),  the Servicer shall act upon the written  request of
the related  Borrower or Manager to the extent the Servicer is required to do so
under the terms of the respective  Mortgage Loan or related documents,  provided
that in the  absence  of  appropriate  written  instructions  from  the  related
Borrower or Manager meeting the  requirements of this Section 3.07, the Servicer
shall have no obligation  to, but will be entitled to, direct the  investment of
funds in such accounts in Permitted Investments.  All such Permitted Investments
shall be held to maturity,  unless payable on demand. Any investment of funds in
an Investment  Account shall be made in the name of the Trustee (in its capacity
as such) or in the name of a nominee of the Trustee. The Trustee shall have sole
control  (except  with  respect to  investment  direction  which shall be in the
control of the Servicer (or NACC, with respect to the Interest  Reserve Account,
or the Special  Servicer,  with respect to any REO Accounts),  as an independent
contractor to the Trust Fund) over each such  investment and any  certificate or
other instrument  evidencing any such investment shall be delivered  directly to
the Trustee or its agent (which shall initially be the Servicer),  together with
any document of transfer, if any, necessary to transfer title to such investment
to the Trustee or its  nominee.  The  Trustee  shall have no  responsibility  or
liability with respect to the investment directions of the Servicer, the Special
Servicer,  NACC,  any  Borrower  or Manager or any losses  resulting  therefrom,
whether from  Permitted  Investments  or otherwise.  The Servicer  shall have no
responsibility  or liability with respect to the investment  directions of NACC,
the Special Servicer, any Borrower or Manager or any losses resulting therefrom,
whether from Permitted Investments or otherwise. In the event amounts on deposit
in an  Investment  Account are at any time  invested  in a Permitted  Investment
payable on demand, the Servicer (or the Special Servicer or NACC, as applicable)
shall:

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

     (y)  demand   payment  of  all  amounts  due   thereunder   promptly   upon
          determination  by the  Servicer (or the Special  Servicer or NACC,  as
          applicable)  that such  Permitted  Investment  would not  constitute a
          Permitted  Investment in respect of funds thereafter on deposit in the
          related Investment Account.

     (b) All income and gain realized from  investment of funds deposited in any
Investment Account shall be for the benefit of the Servicer (except with respect
to the investment of funds deposited in (i) any Borrower Account, which shall be
for the  benefit  of the  related  Borrower  to the  extent  required  under the
Mortgage  Loan or applicable  law, (ii) any REO Account,  which shall be for the
benefit of the Special  Servicer or (iii) the Interest  Reserve  Account,  which
shall be for the benefit of NACC) and, if held in the Collection  Account or REO
Account shall be subject to withdrawal by the Servicer or the Special  Servicer,
as  applicable,   in  accordance  with  Section  3.06  or  Section  3.17(b),  as
applicable,  and if held in the Interest  Reserve  Account,  shall be subject to
withdrawal  by NACC  pursuant to written  instructions.  The  Servicer  (or with
respect  to any REO  Account,  the  Special  Servicer,  or with  respect  to the
Interest  Reserve  Account,  NACC)  shall  deposit  from its own funds  into the
Collection  Account,  any  REO  Account  or the  Interest  Reserve  Account,  as
applicable,  the amount of any loss  incurred  in respect of any such  Permitted
Investment  immediately upon realization of such loss; provided,  however,  that
the Servicer, Special Servicer, or NACC, as applicable, may reduce the amount of
such payment to the extent it forgoes any investment  income in such  Investment
Account  otherwise  payable to it. The Servicer  shall also deposit from its own
funds in any  Borrower  Account  the amount of any loss  incurred  in respect of
Permitted  Investments,  except to the extent that  amounts are invested for the
benefit of the Borrower under the terms of the Mortgage Loan or applicable law.

     (c)  Except as  otherwise  expressly  provided  in this  Agreement,  if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default  occurs  in any  other  performance  required  under any  Permitted
Investment,  the Trustee or, if the Servicer maintains the account in which such
Permitted  Investment is held,  the Servicer in the name of the Trustee may, and
upon the request of Holders of Certificates representing greater than 50% of the
Percentage  Interests of any Class shall, take such action as may be appropriate
to  enforce  such  payment  or   performance,   including  the  institution  and
prosecution of appropriate proceedings.  In the event the Trustee takes any such
action,  the Trust Fund shall pay or  reimburse  the Trustee for all  reasonable
out-of-pocket  expenses,  disbursements  and  advances  incurred  or made by the
Trustee in connection therewith. In the event that the Trustee does not take any
such  action,  the  Servicer  may take such action at its own cost and  expense,
except with  respect to any  Borrower  Account as to which the related  Borrower
directs investments, which shall be at the expense of the Trust Fund.

     SECTION 3.08.  Maintenance  of Insurance  Policies and Errors and Omissions
                    and Fidelity Coverage.

     (a) The Servicer on behalf of the Trustee,  as  mortgagee,  shall cause the
related  Borrower to  maintain,  to the extent  required by each  Mortgage  Loan
(other than REO Mortgage Loans), and if the Borrower does not so maintain, shall
itself  maintain  (subject  to  the  provisions  of  this  Agreement  concerning
Nonrecoverable Advances) to the extent the Trustee as mortgagee has an insurable
interest and to the extent available at commercially  reasonable rates, (i) fire
and hazard insurance with extended coverage on the related Mortgaged Property in
an  amount  which is at least  equal to the  lesser of (A) one  hundred  percent
(100%) of the then "full  replacement  cost" of the  improvements and equipment,
(excluding  foundations,  footings and excavation costs),  without deduction for
physical depreciation,  and (B) the outstanding principal balance of the related
Mortgage Loan or such greater amount as is necessary to prevent any reduction in
such  policy by reason of the  application  of  co-insurance  and to prevent the
Trustee thereunder from being deemed a co-insurer and provided such policy shall
include a "replacement cost" rider, (ii) insurance providing coverage against 12
months  (or such  longer  period or with such  extended  period  endorsement  as
provided in the related Mortgage or other loan document) of rent  interruptions,
provided,  that no such  business  interruption  insurance  is required  for the
Carmax  Credit Lease Loans or the Circuit City Credit Lease Loans and (iii) such
other  insurance  as is required in the related  Mortgage  Loan.  All  insurance
referred to above for Mortgaged  Properties  shall be from a Qualified  Insurer.
The Special  Servicer  shall  maintain fire and hazard  insurance  with extended
coverage on each REO  Property  (subject  to the  provisions  of this  Agreement
concerning  Nonrecoverable Advances) in an amount which is at least equal to one
hundred percent (100%) of the then "full  replacement  cost" of the improvements
and equipment (excluding  foundations,  footings and excavation costs),  without
deduction for physical  depreciation.  If the Special Servicer does not maintain
the  insurance  described  in  the  preceding  sentence  or the  required  flood
insurance  described  below,  the Servicer shall,  as soon as practicable  after
receipt of notice of such failure,  maintain such insurance, and if the Servicer
does not maintain such insurance,  the insurance  required in the first sentence
of this Section 3.08(a) or the required flood insurance  described below (if the
related Borrower fails to maintain such  insurance),  the Trustee shall, as soon
as practicable after receipt of notice of such failure,  maintain such insurance
and if the Trustee does not maintain such  insurance,  the Fiscal Agent shall do
so,  provided that, in each such case,  such  obligation  will be subject to the
provisions of this Agreement  concerning  Nonrecoverable  Advances.  The Special
Servicer shall maintain,  with respect to each REO Property (i) public liability
insurance  providing  such coverage  against such risks as the Special  Servicer
determines,  consistent with the related Mortgage and the Servicing Standard, to
be in the best interests of the Trust Fund,  (ii) insurance  providing  coverage
against 24 months of rent  interruptions  and (iii) such other  insurance as was
required  pursuant to the terms of the related  Mortgage Loan. All insurance for
an REO Property shall be from a Qualified Insurer.  Any amounts collected by the
Servicer or the Special  Servicer  under any such  policies  (other than amounts
required to be applied to the  restoration  or repair of the  related  Mortgaged
Property or amounts to be released to the Borrower in accordance  with the terms
of the related Mortgage) shall be deposited into the Collection Account pursuant
to Section  3.05,  subject to  withdrawal  pursuant  to Section  3.06.  Any cost
incurred  by  the  Servicer,  Special  Servicer,  Trustee  or  Fiscal  Agent  in
maintaining  any such  insurance  shall  not,  for the  purpose  of  calculating
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan,  notwithstanding that the terms of such Mortgage Loan
so permit. It is understood and agreed that no other additional  insurance other
than flood insurance or earthquake insurance subject to the conditions set forth
below is to be required  of any  Borrower or to be  maintained  by the  Servicer
other than  pursuant to the terms of the related  Mortgage  and pursuant to such
applicable  laws and  regulations  as shall at any time be in force and as shall
require such additional insurance.  If the Mortgaged Property (other than an REO
Property) is located in a federally  designated  special flood hazard area,  and
the Servicer,  in performing its  obligations  hereunder in accordance  with the
Servicing  Standard,  is aware of such  location,  the  Servicer  shall  use its
reasonable best efforts to cause the related Borrower to maintain, to the extent
required  by  each  Mortgage  Loan,  and if the  related  Borrower  does  not so
maintain,  will itself  obtain  (subject  to the  provisions  of this  Agreement
concerning  Nonrecoverable  Advances) flood insurance in respect  thereof.  Such
flood  insurance  shall be in an amount  equal to the  lesser of (i) the  unpaid
principal  balance of the related  Mortgage Loan and (ii) the maximum  amount of
such insurance required by the terms of the related Mortgage and as is available
for the related  property under the national flood insurance  program  (assuming
that the  area in which  such  property  is  located  is  participating  in such
program).  If an REO Property (i) is located in a federally  designated  special
flood  hazard  area or (ii) is  related  to a Mortgage  Loan  pursuant  to which
earthquake insurance was in place at the time of origination and continues to be
available at commercially  reasonable  rates,  the Special  Servicer will obtain
(subject to the provisions of this Agreement concerning Nonrecoverable Advances)
flood  insurance  and/or  earthquake  insurance  in  respect  thereof  providing
substantially the same coverage as described in the preceding sentences or, with
respect to earthquake insurance, in the amount required by the Mortgage Loan or,
if not  specified,  in-place at  origination.  If at any time during the term of
this Agreement a recovery under a flood or fire and hazard  insurance  policy in
respect of an REO  Property is not  available  but would have been  available if
such insurance were maintained  thereon in accordance with the standards applied
to Mortgaged Properties described herein, the Special Servicer shall (subject to
the provisions of this Agreement concerning  Nonrecoverable Advances) either (i)
immediately  deposit into the  Collection  Account from its own funds the amount
that would have been  recovered or (ii) apply to the  restoration  and repair of
the property  from its own funds the amount that would have been  recovered,  if
such  application  would be consistent  with the Servicing  Standard;  provided,
however, that the Special Servicer shall not be responsible for any shortfall in
insurance  proceeds  resulting  from an insurer's  refusal or inability to pay a
claim. In the case of any insurance otherwise required to be maintained pursuant
to this  Section  that is not being so  maintained  because the  Servicer or the
Special  Servicer,  as applicable,  has  determined  that it is not available at
commercially  reasonable  rates,  the  Servicer  or  the  Special  Servicer,  as
applicable,  shall  deliver an  Officer's  Certificate  to the  Trustee and each
Rating Agency which details the steps that were taken in seeking such  insurance
and the factors which led to the  determination  that such  insurance was not so
available.  Costs to the Servicer or Special  Servicer of maintaining  insurance
policies  pursuant to this Section 3.08 shall be paid by the Servicer or Special
Servicer as a Property  Advance  and shall be  reimbursable  to the  Servicer or
Special Servicer with interest at the Advance Rate, which  reimbursement  may be
effected under Section 3.06(ii) or (vii).

     The  Servicer  (or the  Special  Servicer,  with  respect to the  Specially
Serviced Mortgage Loans) agrees to prepare and present, on behalf of itself, the
Trustee and the  Certificateholders,  claims under each related insurance policy
maintained  pursuant to this Section  3.08(a) in a timely  fashion in accordance
with the terms of such policy and to take such reasonable steps as are necessary
to receive payment or to permit recovery thereunder.

     All insurance  policies  required  hereunder  shall name the Trustee or the
Servicer or the Special Servicer, on behalf of the Trustee as the mortgagee,  as
loss payee.

     Notwithstanding  the  foregoing  provisions  of this Section  3.08(a),  the
Servicer may permit the Credit Tenants with respect to Circuit City Credit Lease
Loans and the Carmax Credit Lease Loans to self-insure with respect to the risks
required to be insured  against by this Section  3.08(a) in accordance  with the
terms of the related  Credit Lease,  and, with respect to certain credit tenants
at certain of the Mortgaged  Properties who currently are self-insured for their
portion of such  Mortgaged  Property as of the Closing  Date,  the  Servicer may
permit such tenant to continue to self-insure.

     Any  determination  made by the Servicer or Special Servicer that insurance
is not  commercially  reasonably  available  shall be subject to confirmation by
Fitch, DCR and S&P that such  determination  not to purchase such insurance will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
ratings assigned to the Certificates  rated by Fitch, DCR and S&P, provided that
the Servicer  and the Special  Servicer  shall not be required to maintain  such
insurance while Fitch and S&P consider such determination.

     (b) (I) If the Servicer or the Special Servicer, as applicable, obtains and
maintains a blanket  insurance policy insuring against fire and hazard losses on
all of the  Mortgaged  Properties  (other than REO  Properties)  as to which the
related Borrower has not maintained  insurance  required by the related Mortgage
Loan or on all of the REO Properties,  as the case may be, it shall conclusively
be  deemed  to  have  satisfied  its  respective   obligations   concerning  the
maintenance of insurance coverage set forth in Section 3.08(a). Any such blanket
insurance  policy  shall be  maintained  with a  Qualified  Insurer.  A  blanket
insurance policy may contain a deductible  clause, in which case the Servicer or
the Special  Servicer,  as applicable,  shall, in the event that (i) there shall
not have been maintained on the related  Mortgaged  Property a policy  otherwise
complying with the provisions of Section 3.08(a), and (ii) there shall have been
one or more losses  which  would have been  covered by such a policy had it been
maintained,  immediately  deposit into the Collection Account from its own funds
the  amount not  otherwise  payable  under the  blanket  policy  because of such
deductible clause to the extent that any such deductible  exceeds the deductible
limitation  that  pertained to the related  Mortgage Loan, or, in the absence of
any such deductible  limitation,  the deductible  limitation which is consistent
with the Servicing  Standard.  In connection  with its activities as Servicer or
the Special  Servicer  hereunder,  as  applicable,  the  Servicer or the Special
Servicer, respectively,  agrees to prepare and present, on behalf of itself, the
Trustee and  Certificateholders,  claims under any such blanket  policy which it
maintains in a timely fashion in accordance with the terms of such policy and to
take  such  reasonable  steps as are  necessary  to  receive  payment  or permit
recovery thereunder.

         (II) If the Servicer or the Special Servicer, as applicable, causes any
Mortgaged  Property  or REO  Property  to be  covered by a master  force  placed
insurance policy, such policy shall be issued by a Qualified Insurer and provide
no less coverage in scope and amount for such Mortgaged Property or REO Property
than the  insurance  required to be  maintained  pursuant to Section  3.08(a) in
which case the Servicer or Special Servicer shall conclusively be deemed to have
satisfied its respective  obligations to maintain  insurance pursuant to Section
3.08(a). Such policy may contain a deductible clause, in which case the Servicer
or the Special Servicer, as applicable, shall, in the event that (i) there shall
not have been  maintained  on the related  Mortgaged  Property or REO Property a
policy  otherwise  complying  with the provisions of Section  3.08(a),  and (ii)
there shall have been one or more losses which would have been covered by such a
policy had it been maintained,  immediately  deposit into the Collection Account
from its own funds the amount not otherwise payable under such policy because of
such  deductible to the extent that any such  deductible  exceeds the deductible
limitation  that  pertained to the related  Mortgage Loan, or, in the absence of
any such deductible  limitation,  the deductible  limitation which is consistent
with the Servicing Standard.

     (c) The Servicer and the Special Servicer shall maintain a fidelity bond in
the form and  amount  that  would  meet the  servicing  requirements  of prudent
institutional  commercial  mortgage  lenders and loan servicers with the Trustee
named as loss payee.  The Servicer and the Special Servicer each shall be deemed
to have complied with this  provision if one of its  respective  Affiliates  has
such  fidelity  bond  coverage  and,  by the terms of such  fidelity  bond,  the
coverage afforded  thereunder  extends to the Servicer and the Special Servicer,
as applicable.  In addition, the Servicer and the Special Servicer shall keep in
force  during  the term of this  Agreement  a policy or  policies  of  insurance
covering  loss  occasioned  by the  errors and  omissions  of its  officers  and
employees in  connection  with its  obligations  to service the  Mortgage  Loans
hereunder in the form and amount that would meet the servicing  requirements  of
prudent  institutional  commercial  mortgage lenders and loan servicers with the
Trustee named as loss payee.  The Servicer or the Special  Servicer  shall cause
each and every sub-servicer for it to maintain, or cause to be maintained by any
agent or contractor  servicing any Mortgage Loan on behalf of such sub-servicer,
a fidelity bond and an errors and omissions  insurance  policy which satisfy the
requirements  for the fidelity  bond and the errors and  omissions  policy to be
maintained by the Servicer pursuant to this Section 3.08(c).  All fidelity bonds
and  policies of errors and  omissions  insurance  obtained  under this  Section
3.08(c) shall be issued by a Qualified Insurer.

     SECTION 3.09.  Enforcement of Due-On-Sale Clauses;  Assumption  Agreements;
                    Defeasance Provisions.

     (a) If any  Mortgage  Loan (other than the Westin  Casuarina  Resort  Loan)
contains a  provision  in the  nature of a  "due-on-sale"  clause,  which by its
terms:

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

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

then,  for so long as such  Mortgage  Loan is included  in the Trust  Fund,  the
Servicer or Special Servicer,  as applicable,  on behalf of the Trust Fund shall
not be required to enforce such due-on-sale  clause and in connection  therewith
shall not be required to (x)  accelerate  payments  thereon or (y)  withhold its
consent to such an  assumption  to the extent  permitted  under the terms of the
related Mortgage Loan if (x) such provision is not exercisable  under applicable
law or such exercise is reasonably  likely to result in meritorious legal action
by the  Borrower  or (y)  the  Servicer  or  Special  Servicer,  as  applicable,
determines,  in  accordance  with the  Servicing  Standard,  that  granting such
consent  would be likely to result  in a greater  recovery,  on a present  value
basis  (discounting at the related Mortgage Rate) than would enforcement of such
clause.  If the Servicer or Special  Servicer,  as applicable,  determines  that
granting  of such  consent  would  likely  result in a greater  recovery or such
provision  is not legally  enforceable,  the  Servicer or Special  Servicer,  as
applicable,  is authorized to take or enter into an assumption agreement from or
with the Person to whom the related  Mortgaged  Property has been or is about to
be  conveyed,  and to release the  original  Borrower  from  liability  upon the
Mortgage Loan and substitute the new Borrower as obligor thereon, provided, that
(a) the credit status of the  prospective new Borrower is in compliance with the
Servicer's or Special  Servicer's  regular  commercial  mortgage  origination or
servicing  standards  and criteria  (as  evidenced in writing by the Servicer or
Special  Servicer) and the terms of the related Mortgage and (b) the Servicer or
Special  Servicer has received  written  confirmation  from each of Fitch,  DCR,
Moody's  and S&P that such  assumption  or  substitution  would  not,  in and of
itself,  cause a  downgrade,  qualification  or  withdrawal  of the then current
ratings  assigned to the  Certificates;  provided,  however,  that if the Stated
Principal Balance of such Mortgage Loan is less than the lesser of (x) 2% of the
total  aggregate  Stated  Principal  Balances  of the  Mortgage  Loans  and  (y)
$30,000,000, and is not one of the ten largest Mortgage Loans in the Trust Fund,
such written confirmation shall not be required from any of the Rating Agencies.
In  connection  with each such  assumption or  substitution  entered into by the
Special  Servicer,  the Special  Servicer shall give prior notice thereof to the
Servicer.  The Servicer or Special  Servicer,  as  applicable,  shall notify the
Trustee that any such assumption or substitution agreement has been completed by
forwarding  to the Trustee  (with a copy to the  Servicer,  if  applicable)  the
original  copy of such  agreement,  which  copies  shall be added to the related
Mortgage File and shall, for all purposes, be considered a part of such Mortgage
File to the same extent as all other  documents and  instruments  constituting a
part thereof.

         Prior to waiving any "due on sale" clause,  taking or entering into any
assumption agreement or permitting the release of a Borrower and substitution of
a new  Borrower  with  respect to any Mortgage  Loan,  the Servicer  shall first
provide to the Special Servicer a copy of its  recommendation  and the materials
upon which such recommendation is based and then provide the Special Servicer an
opportunity during a four Business Day period prior to taking any such action to
confer with them as to the advisability of such action (it being understood that
the  Servicer  shall not have any  obligation  to  follow  any  instructions  or
directions given to them by the Special Servicer with respect to such actions).

     (b) If any  Mortgage  Loan (other than the Westin  Casuarina  Resort  Loan)
contains a provision in the nature of a  "due-on-encumbrance"  clause,  which by
its terms:

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

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

then the Servicer or Special  Servicer,  as  applicable,  on behalf of the Trust
Fund,  shall not be required to enforce  such  due-on-encumbrance  clause and in
connection  therewith will not be required to (i) accelerate the payments on the
related  Mortgage Loan or (ii) withhold its consent to such lien or encumbrance,
if  the  Servicer  or  Special  Servicer,  as  applicable,  (x)  determines,  in
accordance with the Servicing  Standard,  that such consent would be in the best
interests of the Trust Fund and (y) receives  prior  written  confirmation  from
each of Fitch, Moody's, DCR and S&P that granting such consent would not, in and
of itself,  cause a downgrade,  qualification  or  withdrawal of any of the then
current ratings assigned to the Certificates.

     Prior to  waiving  any  "due on  encumbrance"  clause,  or  permitting  the
creation of any lien or other encumbrance on a Mortgaged Property,  the Servicer
shall first provide to the Special Servicer a copy of its recommendation and the
materials upon which such  recommendation  is based and then provide the Special
Servicer an  opportunity  during a four  Business Day period prior to taking any
such action to confer with them as to the  advisability of such action (it being
understood  that the  Servicer  shall  not have any  obligation  to  follow  any
instructions or directions given to them by the Special Servicer with respect to
such actions).

     (c) Nothing in this Section 3.09 shall constitute a waiver of the Trustee's
right,  as the  mortgagee of record,  to receive  notice of any  assumption of a
Mortgage Loan, any sale or other transfer of the related  Mortgaged  Property or
the creation of any lien or other  encumbrance  with  respect to such  Mortgaged
Property.

     (d) In  connection  with the taking of, or the failure to take,  any action
pursuant to this Section  3.09,  neither the  Servicer nor the Special  Servicer
shall  agree to  modify,  waive or  amend,  and no  assumption  or  substitution
agreement  entered into pursuant to Section 3.09(a) shall contain any terms that
are different  from,  any term of any Mortgage  Loan or the related Note,  other
than pursuant to Section 3.30.

     (e) With  respect to any  Mortgage  Loan (other  than the Westin  Casuarina
Resort Loan) which permits release of Mortgaged Properties through defeasance:

       (i)    In the event such  Mortgage  Loan  requires  that the  Servicer on
              behalf  of the  Trustee  purchase  the  required  U.S.  government
              obligations,   the  Servicer   shall  purchase  (upon  receipt  of
              sufficient  funds  from  the  Borrower  exercising  such  right of
              defeasance)  such obligations in accordance with the terms of such
              Mortgage  Loan;  provided,  that the Servicer shall not accept the
              amounts paid by the related  Borrower to effect  defeasance  until
              acceptable U.S. government obligations have been identified.

       (ii)   In the event that such Mortgage Loan permits the assumption of the
              obligations  of the related  Borrower  by a  successor  mortgagor,
              prior  to  permitting  such  assumption  and  to  the  extent  not
              inconsistent  with such Mortgage  Loan,  the Servicer shall obtain
              written  confirmation from each Rating Agency that such assumption
              would not, in and of itself,  cause a downgrade,  qualification or
              withdrawal   of  the  then   current   ratings   assigned  to  the
              Certificates.

       (iii)  To the  extent  not  inconsistent  with such  Mortgage  Loan,  the
              Servicer  shall  require an  Opinion  of  Counsel  to the  related
              Borrower  (which  shall be an expense of the related  Borrower) to
              the effect that the Trustee has a first priority security interest
              in the defeasance deposit and the U.S. government  obligations and
              the  assignment  thereof is valid and  enforceable;  such opinion,
              together with any other  certificates  or documents to be required
              in connection with such defeasance  shall be in form and substance
              acceptable to each Rating Agency.

       (iv)   To the  extent  not  inconsistent  with  the  Mortgage  Loan,  the
              Servicer  shall  require a certificate  at the related  Borrower's
              expense from an Independent certified public accountant certifying
              that the U.S. government  obligations comply with the requirements
              of the related Loan Agreement or Mortgage.

       (v)    Prior to permitting  release of any Mortgaged  Properties  through
              defeasance,  to the  extent  not  inconsistent  with  the  related
              Mortgage Loan, the Servicer shall obtain written confirmation from
              each  Rating  Agency  that such  defeasance  would not,  in and of
              itself, result in a downgrade,  qualification or withdrawal of the
              then current ratings assigned to the Certificates.

       (vi)   Prior to  permitting  release of any  Mortgaged  Property  through
              defeasance,  if the related Mortgage Loan so requires and provides
              for the related  Borrower to pay the cost  thereof,  the  Servicer
              shall require an Opinion of Counsel of the related Borrower to the
              effect  that such  release  will not cause  either the  Upper-Tier
              REMIC or  Lower-Tier  REMIC to fail to  qualify  as a REMIC at any
              time that any  Certificates  are  outstanding or cause a tax to be
              imposed on the Trust Fund under the REMIC Provisions.

     SECTION 3.10. Appraisals; Realization Upon Defaulted Mortgage Loans.

     (a)  Contemporaneously  with the earliest of (i) the effective  date of any
(A) modification of a Mortgage Rate,  principal balance or amortization terms of
any Mortgage  Loan, or any other term of a Mortgage  Loan,  (B) extension of the
Maturity Date of a Mortgage Loan as described below in Section  3.30(c),  or (C)
consent to the release of any  Mortgaged  Property  from the lien of the related
Mortgage other than pursuant to the terms of the related Mortgage Loan, (ii) the
occurrence of any Appraisal Reduction Event, (iii) a default in the payment of a
Balloon Payment, or (iv) the date on which the Special Servicer, consistent with
the  Servicing  Standard,  requests that an Updated  Appraisal be obtained,  the
Servicer (after  consultation with the Special Servicer) shall obtain an Updated
Appraisal;  provided, however, that the Servicer shall not be required to obtain
an Updated Appraisal  pursuant to clauses (i) through (iv) above with respect to
any  Mortgaged  Property for which there exists an appraisal  which is less than
twelve  months  old.  With  respect to the Westin  Casuarina  Resort  Loan,  the
Servicer  will be  permitted  to rely on any Updated  Appraisal  obtained by the
Servicer of Series  1997-D5.  The Servicer  shall obtain letter  updates to each
Updated Appraisal annually and prior to the Special Servicer granting extensions
beyond one year or any subsequent  extension after granting a one year extension
with respect to the same  Mortgage  Loan.  For so long as any Mortgage  Loan for
which an Updated  Appraisal has been obtained is included in the Trust Fund, the
Servicer  shall  obtain a new  Updated  Appraisal  with  respect  to an  Updated
Appraisal  which is more than two years old.  The  Servicer  shall send all such
letter updates and Updated Appraisals to the Rating Agencies.

     (b) Upon the  occurrence of a material  default under a Specially  Serviced
Mortgage Loan, except as otherwise  specifically provided in Section 3.09(a) and
(b),  the  Special  Servicer  may,   consistent  with  the  Servicing  Standard,
accelerate such Specially  Serviced  Mortgage Loan and commence a foreclosure or
other acquisition with respect to the related Mortgaged  Property or Properties,
provided,  that the  Special  Servicer  determines  that such  acceleration  and
foreclosure are more likely to produce a greater recovery to  Certificateholders
on a present value basis (discounting at the related Mortgage Rate) than would a
waiver of such default or an extension or  modification  in accordance  with the
provisions of Section 3.30 hereof.  In connection  with any foreclosure or other
acquisition  as to which  the  Special  Servicer  is not  required  to act under
Instructions  from the Directing  Holders,  the Servicer shall pay the costs and
expenses in any such  proceedings as an Advance unless the Servicer  determines,
in its good faith judgment,  that such Advance would constitute a Nonrecoverable
Advance.  The  Servicer  shall be entitled to  reimbursement  of Advances  (with
interest at the Advance  Rate) made  pursuant to the  preceding  sentence to the
extent permitted by Section  3.06(ii),  (iii) and (vii). If the Special Servicer
is acting pursuant to Instructions, the cost and expenses in any such proceeding
shall  be  paid  by the  Directing  Holders  or the  Special  Servicer,  without
reimbursement therefor by the Trust Fund.

     (c)  If  the  Special  Servicer  elects  to  proceed  with  a  non-judicial
foreclosure  in  accordance  with the laws of the  state or  locality  where the
Mortgaged  Property is located,  the Special  Servicer  shall not be required to
pursue a deficiency  judgment  against the related  Borrower or any other liable
party if the laws of the  state or  locality  do not  permit  such a  deficiency
judgment after a non-judicial foreclosure or if the Special Servicer determines,
in its best  judgment,  that the likely  recovery  if a  deficiency  judgment is
obtained  will not be  sufficient  to warrant  the cost,  time,  expense  and/or
exposure of pursuing the deficiency judgment and such determination is evidenced
by an Officers' Certificate delivered to the Trustee.

     (d) In the event  that  title to any  Mortgaged  Property  is  acquired  in
foreclosure or by deed in lieu of  foreclosure,  the deed or certificate of sale
shall be issued to the Trustee,  or to its nominee  (which shall not include the
Special  Servicer) or a separate  trustee or co-trustee on behalf of the Trustee
as  holder  of  the  Lower-Tier   Regular   Interests  and   Certificateholders.
Notwithstanding  any such  acquisition of title and  cancellation of the related
Mortgage Loan, such Mortgage Loan shall (except for purposes of Section 9.01) be
considered  to be an REO Mortgage Loan held in the Trust Fund until such time as
the  related REO  Property  shall be sold by the Trust Fund and shall be reduced
only by collections net of expenses. Consistent with the foregoing, for purposes
of all calculations hereunder, so long as such Mortgage Loan shall be considered
to be an outstanding Mortgage Loan:

       (i)    it shall be assumed that,  notwithstanding  that the  indebtedness
              evidenced  by the related  Note shall have been  discharged,  such
              Note and, for purposes of determining the Stated Principal Balance
              thereof, the related  amortization  schedule in effect at the time
              of any such acquisition of title shall remain in effect; and

       (ii)   Subject to Section 1.02(b), Net REO Proceeds received in any month
              shall be applied to amounts that would have been payable under the
              related  Note in  accordance  with the terms of such Note.  In the
              absence of such terms,  Net REO  Proceeds  shall be deemed to have
              been  received  first in  payment  of the  accrued  interest  (not
              including  Excess  Interest) that remained unpaid on the date that
              the related REO Property was acquired by the Trust Fund; second in
              respect of the  delinquent  principal  installments  that remained
              unpaid on such date; and thereafter,  Net REO Proceeds received in
              any month  shall be applied  to the  payment  of  installments  of
              principal and accrued  interest on such Mortgage Loan deemed to be
              due and payable in accordance with the terms of such Note and such
              amortization  schedule  until such principal has been paid in full
              and then to Excess  Interest  and  other  amounts  due under  such
              Mortgage Loan. If such Net REO Proceeds exceed the Monthly Payment
              then  payable,   the  excess  shall  be  treated  as  a  Principal
              Prepayment received in respect of such Mortgage Loan.

     (e)  Notwithstanding  any  provision  herein to the  contrary,  the Special
Servicer  shall not  acquire  for the  benefit  of the Trust  Fund any  personal
property pursuant to this Section 3.10 unless either:

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

       (ii)   the Special  Servicer shall have requested and received an Opinion
              of Counsel  (which  opinion shall be an expense of the  Lower-Tier
              REMIC) to the effect that the holding of such personal property by
              the Lower-Tier REMIC will not cause the imposition of a tax on the
              Lower-Tier REMIC or Upper-Tier REMIC under the REMIC Provisions or
              cause the Lower-Tier  REMIC or Upper-Tier REMIC to fail to qualify
              as a REMIC at any time that any Certificate is outstanding.

     (f)  Notwithstanding  any provision to the contrary in this Agreement,  the
Special  Servicer  shall not, on behalf of the Trust Fund,  obtain  title to any
direct or indirect partnership interest or other equity interest in any Borrower
pledged  pursuant to any pledge agreement unless the Special Servicer shall have
requested and received an Opinion of Counsel  (which opinion shall be an expense
of the Trust Fund) to the effect that the holding of such  partnership  interest
or other equity  interest by the Trust Fund will not cause the  imposition  of a
tax on the Lower-Tier  REMIC or Upper-Tier  REMIC under the REMIC  Provisions or
cause the Lower-Tier  REMIC or Upper-Tier REMIC to fail to qualify as a REMIC at
any time that any Certificate is outstanding.

     (g)  Notwithstanding  any  provision  to the  contrary  contained  in  this
Agreement,  the Special Servicer shall not, on behalf of the Trust Fund,  obtain
title to a  Mortgaged  Property  as a  result  of or in lieu of  foreclosure  or
otherwise,  obtain title to any direct or indirect  partnership  interest in any
Borrower  pledged  pursuant to a pledge  agreement and thereby be the beneficial
owner of a Mortgaged Property, and shall not otherwise acquire possession of, or
take any other action with respect to, any Mortgaged Property if, as a result of
any such  action,  the  Trustee,  for the Trust Fund or the  Certificateholders,
would be considered to hold title to, to be a  "mortgagee-in-possession"  of, or
to be an "owner" or "operator" of such Mortgaged  Property within the meaning of
the  Comprehensive  Environmental  Response,  Compensation  and Liability Act of
1980, as amended from time to time, or any  comparable  law,  unless the Special
Servicer has previously  determined in accordance  with the Servicing  Standard,
based on an updated  environmental  assessment report prepared by an Independent
Person who regularly conducts environmental audits, that:

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

       (ii)   there are no  circumstances  present  at such  Mortgaged  Property
              relating  to the use,  management  or  disposal  of any  Hazardous
              Materials   for   which   investigation,    testing,   monitoring,
              containment,  clean-up or remediation  could be required under any
              currently effective federal, state or local law or regulation,  or
              that, if any such  Hazardous  Materials are present for which such
              action could be required, after consultation with an environmental
              consultant, it would be in the best economic interest of the Trust
              Fund to take such actions  with respect to the affected  Mortgaged
              Property.

     In the  event  that the  environmental  assessment  first  obtained  by the
Special  Servicer  with  respect to a  Mortgaged  Property  indicates  that such
Mortgaged  Property may not be in compliance with applicable  environmental laws
or that Hazardous  Materials may be present but does not definitively  establish
such fact, the Special Servicer shall cause such further  environmental tests to
be conducted by an Independent  Person who regularly  conducts such tests as the
Special   Servicer   shall   deem   prudent   to  protect   the   interests   of
Certificateholders.  Any such tests  shall be deemed  part of the  environmental
assessment obtained by the Special Servicer for purposes of this Section 3.10.

     (h) The environmental  assessment  contemplated by Section 3.10(g) shall be
prepared  within  three  months of the  determination  that such  assessment  is
required by any Independent Person who regularly conducts  environmental  audits
for purchasers of commercial  property where the Mortgaged  Property is located,
as determined by the Special Servicer in a manner  consistent with the Servicing
Standard.   The  Servicer   shall  advance  the  cost  of  preparation  of  such
environmental  assessments  unless the  Servicer  determines,  in its good faith
judgment,  that such  Advance  would be a  Nonrecoverable  Advance.  The Special
Servicer shall provide such information as reasonably  requested by the Servicer
or  Sub-Servicer  to  determine  whether  such  Advance,  if  made,  would  be a
Nonrecoverable  Advance.  The  Servicer  shall be entitled to  reimbursement  of
Advances  (with  interest at the Advance  Rate) made  pursuant to the  preceding
sentence in the manner set forth in Section 3.06.

     (i) If the Special Servicer  determines pursuant to Section 3.10(g)(i) that
a Mortgaged Property is not in compliance with applicable environmental laws but
that it is in the best economic  interest of the Trust Fund to take such actions
as are necessary to bring such Mortgaged Property in compliance therewith, or if
the  Special  Servicer  determines  pursuant  to  Section  3.10(g)(ii)  that the
circumstances  referred to therein  relating to Hazardous  Materials are present
but that it is in the best  economic  interest  of the  Trust  Fund to take such
action with respect to the  containment,  clean-up or  remediation  of Hazardous
Materials affecting such Mortgaged Property as is required by law or regulation,
the  Special  Servicer  shall  take  such  action  as it deems to be in the best
economic  interest of the Trust Fund,  but only if the Trustee has mailed notice
to the Holders of the Regular Certificates of such proposed action, which notice
shall be  prepared  by the Special  Servicer,  and only if the Trustee  does not
receive,  within 30 days of such notification,  instructions from the Holders of
greater than 50% of the aggregate  Voting  Rights of such Classes  directing the
Special Servicer not to take such action.  Notwithstanding the foregoing, if the
Special Servicer reasonably determines that it is likely that within such 30-day
period  irreparable  environmental  harm to such Mortgage  Property would result
from the  presence of such  Hazardous  Materials  and  provides a prior  written
statement to the Trustee  setting forth the basis for such  determination,  then
the Special  Servicer  may take such action to remedy such  condition  as may be
consistent with the Servicing Standard. None of the Trustee, the Servicer or the
Special  Servicer  shall be  obligated to take any action or not take any action
pursuant to this  Section  3.10(i) at the  direction  of the  Certificateholders
unless the  Certificateholders  agree to indemnify the Trustee, the Servicer and
the  Special  Servicer  with  respect to such  action or  inaction.  The Special
Servicer shall advance the cost of any such compliance, containment, clean-up or
remediation unless the Special Servicer determines,  in its good faith judgment,
that such Advance would constitute a Nonrecoverable Advance.

     (j) The  Special  Servicer  shall  report  to the  IRS  and to the  related
Borrower,  in the manner required by applicable law, the information required to
be reported regarding any Mortgaged Property which is abandoned or foreclosed or
regarding any  cancellation of  indebtedness  with respect to any Mortgage Loan.
The Special  Servicer  shall  deliver a copy of any such report to the Servicer,
the Sub-Servicer and the Trustee.

     (k) The costs of any Updated  Appraisal  obtained  pursuant to this Section
3.10 shall be paid by the Servicer as an Advance and shall be reimbursable  from
the Collection  Account (or from the Collateral  Account to the extent  Advances
are otherwise reimbursable therefrom pursuant to this Section 3.10).

     SECTION 3.11. Trustee to Cooperate; Release of Mortgage Files.

     Upon the  payment  in full of any  Mortgage  Loan,  or the  receipt  by the
Servicer of a  notification  that payment in full has been  escrowed in a manner
customary for such purposes,  the Servicer shall immediately  notify the Trustee
or the  Custodian  by 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  pursuant to Section 3.05 have been or will be so deposited)
of a Servicing Officer and shall request delivery to it of the Mortgage File. No
expenses  incurred in connection  with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Trust Fund.

     From time to time upon  request of the  Servicer  or Special  Servicer  and
delivery to the Trustee and the Custodian of a Request for Release,  the Trustee
shall  promptly cause the Custodian to release the Mortgage File (or any portion
thereof)  designated  in  such  Request  for  Release  to the  Servicer  (or the
Sub-Servicer) or Special Servicer,  as applicable.  Upon return of the foregoing
to the Custodian, or in the event of a liquidation or conversion of the Mortgage
Loan  into  an REO  Property,  receipt  by the  Trustee  of a  certificate  of a
Servicing  Officer  stating that such Mortgage Loan was  liquidated and that all
amounts received or to be received in connection with such liquidation which are
required to be deposited into the  Collection  Account or  Distribution  Account
have been so  deposited,  or that such Mortgage Loan has become an REO Property,
the Custodian shall deliver a copy of the Request for Release to the Servicer or
Special Servicer, as applicable.

     Upon  written  certification  of a Servicing  Officer,  the  Trustee  shall
execute and deliver to the Special  Servicer any court  pleadings,  requests for
trustee's sale or other documents  prepared by the Special Servicer,  its agents
or attorneys,  necessary to the  foreclosure  or trustee's  sale in respect of a
Mortgaged Property or to any legal action brought to obtain judgment against any
Borrower  on the Note or  Mortgage  or to obtain a  deficiency  judgment,  or to
enforce  any  other  remedies  or rights  provided  by the Note or  Mortgage  or
otherwise available at law or in equity. Each such certification shall include a
request  that such  pleadings  or  documents  be  executed  by the Trustee and a
statement as to the reason such  documents or pleadings are  required,  and that
the  execution  and  delivery  thereof by the  Trustee  will not  invalidate  or
otherwise affect the lien of the Mortgage,  except for the termination of such a
lien upon completion of the foreclosure or trustee's sale.

     SECTION  3.12.   Servicing  Fees,   Trustee  Fees  and  Special   Servicing
                      Compensation.

     (a) As  compensation  for its activities  hereunder,  the Servicer shall be
entitled with respect to each Mortgage Loan to the Servicing Fee, which shall be
payable  from  amounts  on  deposit  in the  Collection  Account as set forth in
Section  3.06(iv).  The  Servicer's  rights  to the  Servicing  Fee  may  not be
transferred in whole or in part except in connection with the transfer of all or

     (b) As  compensation  for its activities  hereunder,  the Special  Servicer
shall be entitled with respect to each Specially  Serviced  Mortgage Loan to the
Special Servicing  Compensation,  which shall be payable from amounts on deposit
in the  Collection  Account  as set  forth  in  Section  3.06(iv).  The  Special
Servicer's  rights to the Special  Servicing Fee may not be transferred in whole
or in  part  except  in  connection  with  the  transfer  of all of the  Special
Servicer's  responsibilities and obligations under this Agreement.  In addition,
the  Special  Servicer  shall be  entitled  to  receive,  as  Special  Servicing
Compensation, (i) to the extent permitted by applicable law and the related Loan
Documents,  any Assumption  Fees,  modification  fees, loan service  transaction

Special  Servicer  on  any  Specially  Serviced  Mortgage  Loan,  and,  for  any
modification,  extension or other action by the Special Servicer with respect to
any Specially Serviced Mortgage Loan for which the consent of, or review by, the
Servicer is required,  75% of any modification,  extension or other fees payable
by the related Borrower in connection therewith;  and (ii) any interest or other
income  earned on  deposits in the REO  Accounts.  Special  Servicer  shall also
receive from the Sub-Servicer 25% of any loan  modification  fees and Assumption
Fees on Mortgage Loans which are not Specially  Serviced  Mortgage  Loans.  If a
review by, or the consent of, the Servicer is not specifically required pursuant
to the terms hereof  including,  without  limitation,  Section 3.28(l),  Section
3.30(c) or Section  3.30(b)(viii)  (and  provided the Special  Servicer does not

     (c) The  Servicer,  Special  Servicer  and  Trustee  shall be  entitled  to

the  performance of their duties under this Agreement  which are  "unanticipated
expenses  incurred  by the REMIC"  within the  meaning of  Treasury  Regulations
Section 1.860G-1(b)(3)(iii).  Such expenses shall include, by way of example and
not by way of  limitation,  environmental  assessments,  Updated  Appraisals and
appraisals  in  connection  with  foreclosure,  the  fees  and  expenses  of any
administrative  or judicial  proceeding  and expenses  expressly  identified  as
reimbursable in Section 3.06(vii).

     (d) No provision of this Agreement or of the Certificates shall require the
Servicer,  the Special  Servicer,  the Trustee or the Fiscal  Agent to expend or
risk  their  own  funds  or  otherwise  incur  any  financial  liability  in the
performance of any of their duties  hereunder or thereunder,  or in the exercise
of any of their rights or powers, if, in the good faith business judgment of the
Servicer,  Special  Servicer,  Trustee  or  Fiscal  Agent,  as the  case may be,
repayment of such funds would not be ultimately  recoverable from late payments,
Net Insurance Proceeds,  Net Liquidation Proceeds and other collections on or in
respect of the Mortgage  Loans,  or from  adequate  indemnity  from other assets
comprising the Trust Fund against such risk or liability.

     If the Servicer,  the Special Servicer or the Trustee receives a request or
inquiry from a Borrower,  any Certificateholder or any other Person the response
to which would, in the Servicer's or the Trustee's good faith business  judgment
require the assistance of Independent  legal counsel or other  consultant to the
Servicer, the Special Servicer or the Trustee, the cost of which would not be an
expense of the Trust Fund hereunder,  then the Servicer, the Special Servicer or
the  Trustee,  as the case may be,  shall not be  required to take any action in
response   to  such   request  or   inquiry   unless   the   Borrower   or  such
Certificateholder  or such other Person, as applicable,  makes  arrangements for
the payment of the Servicer's,  the Special Servicer's or the Trustee's expenses
associated with such counsel (including,  without limitation, posting an advance
payment for such expenses) satisfactory to the Servicer, the Special Servicer or
the  Trustee,  as  the  case  may  be,  in  its  sole  discretion.  Unless  such
arrangements have been made, the Servicer,  the Special Servicer or the Trustee,
as the case may be,  shall have no  liability  to any Person for the  failure to
respond to such request or inquiry.

medium  reasonably  acceptable to the Trustee.  The information that pertains to
Specially  Serviced Mortgage Loans and REO Properties  reflected in such reports
shall be based solely upon the reports  delivered by the Special Servicer to the

in the form  required  by Section  3.13(f) or shall be provided by means of such

investigation  or inquiry,  the information  and reports  delivered to it by the
Special  Servicer,  and the Trustee shall be entitled to conclusively  rely upon
the Servicer's  reports and the Special  Servicer's  reports without any duty or
obligation  to  recompute,  verify or  recalculate  any of the amounts and other
information  stated  therein  (and  such  reports  may  include  any  reasonable
disclaimers  with  respect  to  information  provided  by third  parties or with

       (i)    At least annually by June 30th, with respect to each Mortgage Loan
              and REO Mortgage Loan (to the extent prepared by and received from
              the  Special  Servicer  in  the  case  of any  Specially  Serviced
              Mortgage  Loan  or REO  Mortgage  Loan),  an  Operating  Statement
              Analysis for the related Mortgaged  Property or REO Property as of
              the end of the preceding  calendar  year,  together with copies of
              the  operating  statements  and rent rolls (but only to the extent
              the related  Borrower is required by the  Mortgage to deliver,  or
              otherwise  agrees to provide such information and, with respect to
              operating   statements  and  rent  rolls  for  Specially  Serviced
              Mortgage Loans and REO Properties, only to the extent requested by
              the Special  Servicer) for the related  Mortgaged  Property or REO
              Property as of the end of the preceding  fiscal year. The Servicer
              shall  use its best  reasonable  efforts  to  obtain  said  annual
              operating  statements  and rent rolls with  respect to each of the
              Mortgage Loans other than Specially Serviced Mortgage Loans or REO
              Mortgage  Loans,  which efforts shall include a letter sent to the
              related  Borrower each quarter  (followed up with telephone calls)
              requesting such annual  operating  statements and rent rolls until
              they are  received to the extent such  action is  consistent  with
              applicable law and the terms of the Mortgage Loans.

       (ii)   Within  thirty days after  receipt by the Servicer (or the Special
              Servicer in the case of a Specially  Serviced Mortgage Loan or REO
              Property) of any annual  operating  statements with respect to any
              Mortgaged  Property or REO Property (to the extent prepared by and
              received  from the Special  Servicer in the case of any  Specially
              Serviced  Mortgage  Loan  or  REO  Property),  an  NOI  Adjustment
              Worksheet for such Mortgaged  Property (with the annual  operating
              statements  attached  thereto as an exhibit) (and such reports may
              include any  reasonable  disclaimers  with respect to  information
              provided by third parties or with respect to assumptions  required
              to be made in the preparation of such reports as the Servicer, the
              Special Servicer or Sub-Servicer deems appropriate).

The Servicer shall  maintain one Operating  Statement  Analysis  report for each
Mortgaged Property and REO Property (to the extent prepared by and received from
the Special  Servicer in the case of any REO Property or any Mortgaged  Property
constituting  security for a Specially  Serviced  Mortgage Loan).  The Operating
Statement  Analysis  report for each  Mortgaged  Property  (other  than any such
Mortgaged Property which is REO Property or constitutes security for a Specially
Serviced Mortgage Loan) is to be updated by the Servicer and such updated report
delivered  to the Trustee  within  thirty days after  receipt by the Servicer of
updated operating statements for such Mortgaged Property.  The Servicer will use
the  "Normalized"  column  from  the NOI  Adjustment  Worksheet  to  update  the
Operating  Statement  Analysis  report  and  will use any  operating  statements
received with respect to any Mortgaged  Property  (other than any such Mortgaged
Property which is REO Property or constitutes  security for a Specially Serviced
Mortgage  Loan) to update  the  Operating  Statement  Analysis  report  for such
Mortgaged Property,  such updates to be completed and copies thereof sent to the
Trustee within thirty days after receipt of the necessary  information (and such
reports may include  any  reasonable  disclaimers  with  respect to  information
provided by third parties or with respect to assumptions  required to be made in
the  preparation  of such  reports as the  Servicer,  the  Special  Servicer  or
Sub-Servicer deems appropriate).

     The  Special  Servicer  will be  required  pursuant  to Section  3.13(g) to
deliver to the  Servicer  the  information  required  pursuant  to this  Section
3.13(d) with respect to Specially Serviced Mortgage Loans and REO Mortgage Loans

beginning in May 1998, the Servicer shall prepare and deliver to the Trustee and
the Special  Servicer,  a Watch List of all Mortgage Loans that the Servicer has
determined are in jeopardy of becoming  Specially  Serviced  Mortgage Loans. For
this purpose, Mortgage Loans that are in jeopardy of becoming Specially Serviced
Mortgage Loans shall include,  without  limitation:  (i) Mortgage Loans having a
current  Debt  Service  Coverage  Ratio  that  is 80% or  less  of the  trailing
twelve-month  Debt Service  Coverage  Ratio as of the Cut-off Date (as stated on
Annex A to the  Prospectus)  or  having a  current  trailing  twelve-month  Debt
Service  Coverage Ratio that is less than 1.05x (other than Credit Lease Loans),
(ii) Mortgage Loans as to which any required inspection of the related Mortgaged

determines  can reasonably be expected to materially  adversely  affect the cash
flow generated by such Mortgaged Property,  (iii) Mortgage Loans which have come
to  the  Servicer's  attention  in the  performance  of its  duties  under  this
Agreement  (without any expansion of such duties by reason  hereof) that (A) any
tenant occupying 25% or more of the space in the related Mortgaged  Property has
vacated  (without being  replaced by a comparable  tenant and lease) or been the
subject of bankruptcy or similar  proceedings  or (B) relate to a borrower or an
affiliate  that is the  subject  of a  bankruptcy  or similar  proceeding,  (iv)
Mortgage  Loans that are at least one Collection  Period  delinquent in payment,
and (v) Mortgage Loans that are within 60 days of maturity (and such reports may
include any reasonable disclaimers with respect to information provided by third
parties or with respect to assumptions required to be made in the preparation of
such  reports as the  Servicer,  the  Special  Servicer  or  Sub-Servicer  deems
appropriate).

events  promptly upon the Special  Servicer  having  knowledge of such event. In
addition, in connection with their servicing of the Mortgage Loans, the Servicer
and the Special  Servicer shall provide to each other and to the Trustee written
notice of any event that  comes to their  knowledge  with  respect to a Mortgage
Loan or REO Property  that the Servicer or the Special  Servicer,  respectively,
determines,  in  accordance  with  Servicing  Standards,  would  have a material
adverse effect on such Mortgage Loan or REO Property, which notice shall include
an explanation as to the reason for such material adverse effect.

     (f) At least one Business Day prior to each Servicer  Remittance  Date, the
Special Servicer shall deliver, or cause to be delivered,  to the Servicer,  DCR

provided by third parties or with respect to assumptions  required to be made in
the  preparation  of such  reports as the  Servicer,  the  Special  Servicer  or
Sub-Servicer deems appropriate).

     (g) The Special  Servicer  shall  deliver or cause to be  delivered  to the
Servicer,  DCR  and  S&P  and,  upon  the  request  of any of the  Trustee,  the
Depositor,  the  Underwriters  or any other Rating  Agency,  to such  requesting
party, the following  materials,  in each case to the extent that such materials
or the  information  on which they are based have been  received  by the Special
Servicer:

       (i)    Annually,  on or before June 10 of each year, commencing with June

              statements  and rent rolls for the related  Mortgaged  Property or
              REO Property as of the end of the  preceding  calendar  year.  The
              Special  Servicer shall use its best reasonable  efforts to obtain
              said annual  operating  statements  and rent rolls with respect to
              each  Mortgaged  Property  constituting  security  for a Specially
              Serviced Mortgage Loan and each REO Property,  which efforts shall
              include a letter sent to the related Borrower or other appropriate
              party each quarter  (followed up with telephone calls)  requesting
              such  annual  operating  statements  and rent rolls until they are
              received.

       (ii)   Within 20 days of receipt by the  Special  Servicer  of any annual
              operating  statements  with  respect  to  any  Mortgaged  Property
              relating to a Specially  Serviced  Mortgage  Loan, or at least six

which  constitutes  security for a Specially  Serviced Mortgage Loan or is a REO
Property  is to be updated  by the  Special  Servicer  and such  updated  report
delivered to the Servicer  within 20 days after receipt by the Special  Servicer
of updated operating  statements for each such Mortgaged Property.  In addition,
the Special  Servicer shall provide each such report to the Servicer in the then
applicable CSSA format.  The Special Servicer will use the  "Normalized"  column
from the NOI  Adjustment  Worksheet to update the Operating  Statement  Analysis
report  and will use any  operating  statements  received  with  respect  to any
Mortgaged Property which constitutes  security for a Specially Serviced Mortgage
Loan or is a REO Property to update the Operating  Statement Analysis report for
such Mortgaged Property, such updates to be completed and copies thereof sent to
the Servicer within 20 days after receipt of the necessary information.

     (h) The Trustee shall be entitled to rely  conclusively on and shall not be
responsible for the content or accuracy of any information provided to it by the
Servicer or the Special Servicer pursuant to this Agreement.

the reporting person during the preceding  calendar year (or such shorter period
from  the  Closing  Date to the end of the  related  calendar  year)  and of its
performance under this Agreement has been made under such officer's supervision,
(ii) that, to the best of such officer's  knowledge,  based on such review,  the
reporting  person  has  fulfilled  all of its  material  obligations  under this
Agreement throughout such year (or such shorter period), or, if there has been a
default in the fulfillment of any such obligation,  specifying each such default
known to such officer, the nature and status thereof and what action it proposes
to take  with  respect  thereto,  (iii)  that,  to the  best  of such  officer's
knowledge,  each related  sub-servicer  has fulfilled its obligations  under its
sub-servicing  agreement  in all  material  respects,  or,  if there  has been a
material  default in the fulfillment of such  obligations,  specifying each such
default  known to such  officer  and the  nature and  status  thereof,  and (iv)
whether it has received any notice regarding  qualification,  or challenging the
status,  of the Upper-Tier  REMIC or Lower-Tier REMIC as a REMIC from the IRS or
any other governmental agency or body.

     SECTION 3.15. Annual Independent Public Accountants' Servicing Report.

     On or before  March 15 of each year,  beginning  with March 15,  1999,  the
Servicer and the Special Servicer (the "reporting person") each at the reporting
person's expense shall cause a firm of nationally recognized  Independent public
accountants  (who may also render other services to the reporting  person) which
is a member of the American Institute of Certified Public Accountants to furnish
a statement (an "Accountant's  Statement") to the Trustee,  the Depositor and to
the Rating Agencies, to the effect that such firm has examined certain documents
and  records  relating to the  servicing  of the  similar  mortgage  loans under
similar  agreements  and  that,  on the  basis  of  such  examination  conducted
substantially in compliance with generally  accepted auditing  standards and the
Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for
Mortgages  serviced for FHLMC,  such  servicing has been conducted in compliance
with similar  agreements  except for such  significant  exceptions  or errors in
records that, in the opinion of such firm, generally accepted auditing standards
and the Uniform  Single  Attestation  Program for Mortgage  Bankers or the Audit
Program for  Mortgages  serviced for FHLMC  require it to report,  in which case
such  exceptions and errors shall be so reported.  Each  reporting  person shall
obtain from the related accountants,  or shall prepare, an electronic version of
each Accountant's  Statement and provide such electronic  version to the Trustee
for filing in accordance  with the  procedures set forth in Section 3.22 hereof.
With respect to any electronic version of an Accountant's  Statement prepared by
the reporting  person,  the reporting person shall receive written  confirmation
from the related accountants that such electronic version is a conformed copy of

     SECTION 3.16. Access to Certain Documentation.

     The Servicer and Special  Servicer shall provide to any  Certificateholders
that are federally  insured financial  institutions,  the Federal Reserve Board,

jurisdiction  of  which  any   Certificateholder  is  subject,   access  to  the
documentation regarding the Mortgage Loans required by applicable regulations of
the Federal  Reserve  Board,  FDIC, OTS or any such  governmental  or regulatory
body, such access being afforded without charge but only upon reasonable request
and during  normal  business  hours at the  offices of the  Servicer  or Special
Servicer.  Nothing in this Section 3.16 shall detract from the obligation of the
Servicer  and  Special  Servicer  to  observe  any  applicable  law  prohibiting
disclosure of information with respect to the Borrowers,  and the failure of the
Servicer and Special Servicer to provide access as provided in this Section 3.16
as a result of such  obligation  shall not  constitute  a breach of this Section
3.16.

     SECTION  3.17.  Title and  Management  of REO  Properties  and REO  Account
                     Properties.

     (a) 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
upon abandonment or reclamation from bankruptcy, the deed or certificate of sale
shall be taken in the name of the  Trustee,  or its  nominee  (which  shall  not
include the Servicer),  or a separate  trustee or  co-trustee,  on behalf of the
Trust Fund. The Special Servicer,  on behalf of the Trust Fund, shall dispose of
any REO Property  prior to the close of the third  calendar  year  following the
year in which  the  Trust  Fund  acquires  ownership  of such REO  Property  for
purposes of Section  860G(a)(8) of the Code,  unless (i) the Special Servicer on
behalf of the  Lower-Tier  REMIC has  applied  for an  extension  of such period
pursuant to Sections  856(e)(3) and 860G(a)(8)(A) of the Code, in which case the
Special  Servicer shall sell such REO Property  within the applicable  extension
period or (ii) the Special Servicer seeks and  subsequently  receives an Opinion
of Counsel (which  opinion shall be an expense of the Trust Fund),  addressed to
the Special  Servicer and  Trustee,  to the effect that the holding by the Trust
Fund of such REO Property for an additional specified period will not cause such
REO Property to fail to qualify as "foreclosure  property" within the meaning of
Section  860G(a)(8)  of the Code  (determined  without  regard to the  exception
applicable  for  purposes  of Section  860D(a) of the Code) at any time that any
Certificate is outstanding, in which event such period shall be extended by such
additional  specified period subject to any conditions set forth in such Opinion
of Counsel. The Special Servicer,  on behalf of the Trust Fund, shall dispose of
any REO  Property  held by the Trust Fund  prior to the last day of such  period
(taking  into account  extensions)  by which such REO Property is required to be
disposed of pursuant to the provisions of the immediately  preceding sentence in
a manner provided under Section 3.18 hereof.  The Special Servicer shall manage,
conserve,  protect  and operate  each REO  Property  for the  Certificateholders
solely for the purpose of its prompt disposition and sale in a manner which does
not cause such REO Property to fail to qualify as "foreclosure  property" within
the meaning of Section 860G(a)(8) of the Code (determined  without regard to the
exception applicable for purposes of Section 860D(a)).

     (b) 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 REO Property as are consistent with the manner
in which the Special  Servicer  manages and operates  similar  property owned or
managed by the Special Servicer or any of its Affiliates,  all on such terms and
for such period as the Special  Servicer  deems to be in the best  interests  of
Certificateholders,  and, in connection  therewith,  the Special  Servicer shall
agree to the payment of management  fees that are consistent with general market
standards.  Consistent with the foregoing,  the Special  Servicer shall cause or
permit to be earned  with  respect to such REO  Property  any "net  income  from
foreclosure  property," within the meaning of Section 860G(c) of the Code, which
is subject to tax under the REMIC Provisions only if it has determined,  and has
so advised  the  Trustee in  writing,  that the  earning of such income on a net
after-tax basis could  reasonably be expected to result in a greater recovery on
behalf of  Certificateholders  than an alternative method of operation or rental
of such REO  Property  that  would not be  subject  to such a tax.  The  Special
Servicer  shall  segregate and hold all revenues  received by it with respect to
any REO Property  separate  and apart from its own funds and general  assets and
shall  establish  and  maintain  with  respect to any REO  Property a segregated
custodial  account (each, an "REO Account"),  each of which shall be an Eligible
Account and shall be entitled "LaSalle  National Bank, as Trustee,  in trust for
Holders of Nomura Asset Securities Corporation, Commercial Mortgage Pass-Through
Certificates,  Series  1998-D6,  REO  Account."  The Special  Servicer  shall be
entitled to withdraw for its account any interest or investment income earned on
funds deposited in an REO Account to the extent provided in Section 3.07(b). The
Special  Servicer  shall  deposit or cause to be  deposited  in the REO  Account
within one Business Day after  receipt all revenues  received by it with respect
to any REO  Property  (other  than  Liquidation  Proceeds),  and shall  withdraw
therefrom funds necessary for the proper  operation,  management and maintenance
of such REO Property and for other Property  Protection Expenses with respect to
such REO Property, including:

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

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

       (iii)  all  costs and  expenses  reasonable  and  necessary  to  protect,
              maintain,  manage,  operate,  repair and restore any REO Property;
              and

       (iv)   any taxes imposed on the Upper Tier REMIC or  Lower-Tier  REMIC in
              respect of net income from foreclosure property in accordance with
              Section 4.05.

     To the extent that such REO Proceeds are  insufficient for the purposes set
forth in clauses (i) through  (iii) above and the Special  Servicer has provided
written  notice of such  shortfall to the Servicer at least five  Business  Days
prior to the date that such  amounts are due,  the  Servicer  shall  advance the
amount of such  shortfall  unless  the  Servicer  determines,  in its good faith
judgment,  that  such  Advance  would  be a  Nonrecoverable  Advance;  provided,
however,  the Special Servicer shall make reasonable efforts to request Advances
once in any 30 day period to satisfy all such  shortfalls.  The Special Servicer
shall  reasonably  cooperate  with the  Servicer in  providing  any  information
required to determine  whether an Advance would be a Nonrecoverable  Advance and
the Servicer shall  reasonably  cooperate with the Special Servicer in providing
any   information   required  to  determine   whether  an  Advance  would  be  a
Nonrecoverable  Advance.  If the  Servicer  does not make  any such  Advance  in
violation of the  immediately  preceding  sentence,  the Trustee shall make such
Advance;  and if the Trustee  fails to make any such  Advance,  the Fiscal Agent
shall make such Advance,  unless in either case, the Trustee or the Fiscal Agent
determines that such Advance would be a Nonrecoverable  Advance. The Trustee and
the Fiscal Agent shall be entitled to rely,  conclusively,  on any determination
by the Servicer that an Advance, if made, would be a Nonrecoverable Advance. The
Trustee and the Fiscal Agent, in determining  whether or not a proposed  Advance
would be a Nonrecoverable  Advance, shall be subject to the standards applicable
to the Servicer  hereunder.  The Servicer,  the Trustee or the Fiscal Agent,  as
applicable,  shall be entitled to  reimbursement of such Advances (with interest
at the Advance Rate) made pursuant to the preceding sentence,  to the extent set
forth in Section 3.06. The Special Servicer shall withdraw from each REO Account
and remit to the Servicer for deposit into the  Collection  Account on a monthly
basis  prior to or on the  related  Due Date the Net REO  Proceeds  received  or
collected from each REO Property,  except that in determining the amount of such
Net REO Proceeds, the Special Servicer may retain in each REO Account reasonable
reserves for repairs,  replacements and necessary capital improvements and other
related expenses.

     Notwithstanding the foregoing, the Special Servicer shall not:

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

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

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

       (iv)   Directly  Operate or allow any Person to Directly  Operate any REO
              Property  on any  date  more  than  90  days  after  its  date  of
              acquisition   by  the  Trust  Fund,   unless  such  Person  is  an
              Independent Contractor;

unless,  in any such case,  the Special  Servicer has  requested and received an
Opinion of Counsel  addressed  to the Special  Servicer  and the Trustee  (which
opinion  shall be an expense of the Trust  Fund) to the effect  that such action
will not cause such REO  Property to fail to qualify as  "foreclosure  property"
within the meaning of Section 860G(a)(8) of the Code (determined  without regard
to the exception  applicable for purposes of Section 860D(a) of the Code) at any
time that it is held by the Trust Fund,  in which case the Special  Servicer may
take such actions as are specified in such Opinion of Counsel.

     The Special  Servicer  shall be required  to contract  with an  Independent
Contractor  (acceptable  to each  Rating  Agency (in the case of DCR only if the
Stated Principal Balance of such Mortgage Loan exceeds 2% of the total aggregate
Stated  Principal  Balance  of the  Mortgage  Loans)  as  evidenced  by  written
confirmation that contracting with such Independent Contractor would not, in and
of itself cause a downgrade,  qualification  or  withdrawal  of the then current
ratings assigned to any Class of  Certificates),  the fees and expenses of which
shall be an expense of the Trust Fund and payable out of REO  Proceeds,  for the
operation and management of any REO Property, within 90 days of the Trust Fund's
acquisition thereof (unless the Special Servicer shall have provided the Trustee
with an Opinion of Counsel that the operation and management of any REO Property
other than through an Independent  Contractor  shall not cause such REO Property
to fail to qualify as "foreclosure  property" within the meaning of Code Section
860G(a)(8))  (which  opinion  shall be an expense of the Trust  Fund),  provided
that:

       (i)    the terms and  conditions of any such contract shall be reasonable
              and  customary  for the area and type of property and shall not be
              inconsistent herewith;

       (ii)   any such  contract  shall  require,  or shall be  administered  to
              require,  that  the  Independent  Contractor  pay  all  costs  and
              expenses  incurred in connection with the operation and management
              of such REO Property,  including those listed above, and remit all
              related  revenues  (net of such costs and expenses) to the Special
              Servicer  as soon as  practicable,  but in no event  later than 30
              days following the receipt thereof by such Independent Contractor;

       (iii)  none of the  provisions  of this Section  3.17(b)  relating to any
              such  contract or to actions  taken  through any such  Independent
              Contractor  shall be deemed to relieve the Special Servicer of any
              of its duties and  obligations to the Trust Fund or the Trustee on
              behalf of the Certificateholders with respect to the operation and
              management of any such REO Property; and

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

     The Special Servicer shall be entitled to enter into any agreement with any
Independent  Contractor  performing  services  for it  related to its duties and
obligations  hereunder  for  indemnification  of the  Special  Servicer  by such
Independent  Contractor,  and nothing in this Agreement shall be deemed to limit
or modify such indemnification.

     (c)  Promptly  following  any  acquisition  by  the  Trust  Fund  of an REO
Property,  the Special  Servicer  shall  notify the  Servicer  and  Sub-Servicer
thereof,  and, upon receipt of such notice, the Servicer shall obtain an Updated
Appraisal thereof, but only in the event that any Updated Appraisal with respect
thereto is more than 12 months old, in order to determine  the fair market value
of such REO Property and shall notify the  Depositor,  the Special  Servicer and
the Trustee hereto of the results of such appraisal. Any such appraisal shall be
conducted by an appraiser who is an MAI and the cost thereof shall be an expense
of the Trust Fund. The Servicer shall obtain a new Updated Appraisal or a letter
update every 12 months thereafter.

     (d) When and as  necessary,  the  Special  Servicer  shall  deliver  to the
Trustee a statement prepared by the Special Servicer setting forth the amount of
net income or net loss, as determined for federal income tax purposes, resulting
from the operation and  management of a trade or business on, the  furnishing or
rendering  of a  non-customary  service to the tenants of, or the receipt of any
other amount not  constituting  Rents from Real  Property in respect of, any REO
Property in accordance with Sections 3.17(a) and 3.17(b).

     SECTION 3.18. Sale of Specially Serviced Mortgage Loans and REO Properties.

     (a) With respect to any  Specially  Serviced  Mortgage Loan or REO Property
which  the  Special  Servicer  has  determined  to sell in  accordance  with the
provisions  hereof,  the  Special  Servicer  shall  deliver  to the  Trustee  an
Officers'  Certificate  to the effect  that  pursuant to the terms  hereof,  the
Special Servicer has determined to sell such Specially Serviced Mortgage Loan or
REO Property in accordance with this Section 3.18. The Special Servicer may then
offer to sell to any  Person any  Specially  Serviced  Mortgage  Loan or any REO
Property or,  subject to the  following  sentence,  purchase any such  Specially
Serviced  Mortgage  Loan or REO Property (in each case at the  Repurchase  Price
therefor),  but shall,  in any event, so offer to sell any REO Property no later
than the time  determined by the Special  Servicer to be sufficient to result in
the sale of such REO Property  within the period  specified in Section  3.17(a).
The Special  Servicer  shall  deliver such  Officers'  Certificate  and give the
Trustee not less than ten Business Days prior written notice of its intention to
sell any Specially  Serviced  Mortgage  Loan or REO Property,  in which case the
Special  Servicer  shall  accept the highest  offer (of at least  three  offers)
received  from any Person for any  Specially  Serviced  Mortgage Loan or any REO
Property in an amount at least equal to the Repurchase Price therefor or, at its
option,  if it has  received  no offer at least  equal to the  Repurchase  Price
therefor,  purchase the Specially  Serviced Mortgage Loan or REO Property at the
Repurchase Price.

     In the absence of any such offer or purchase by the Special  Servicer,  the
Special Servicer shall accept the highest offer received from any Person that is
determined  by  the  Special  Servicer  to be a fair  price,  as  determined  in
accordance with Section 3.18(b),  for such Specially  Serviced  Mortgage Loan or
REO  Property,  if the  highest  offeror is a Person  other  than an  Interested
Person,  or is determined  to be a fair price by the Trustee in accordance  with
Section 3.18(b), if the highest offeror is an Interested Person;  provided, that
the Trustee  shall be entitled to engage,  at the expense of the Trust Fund,  an
Independent  appraiser  to determine  whether the highest  offer is a fair price
and, further provided,  that if the highest offeror is an Interested Person such
offer shall not be accepted if it is less than the Repurchase Price,  unless the
Rating  Agencies have confirmed,  in writing,  that such acceptance will not, in
itself, result in the qualification, downgrade or withdrawal of the then-current
ratings assigned to the Certificates.  Notwithstanding  anything to the contrary
herein,  neither  the  Trustee,  in  its  individual  capacity,  nor  any of its
Affiliates may make an offer or purchase any Specially Serviced Mortgage Loan or
any REO Property pursuant hereto.

     The Special  Servicer  shall not be  obligated  by either of the  foregoing
paragraphs  or  otherwise  to accept the highest  offer if the Special  Servicer
determines,  in accordance with the Servicing  Standard,  that rejection of such
offer would be in the best interests of the Certificateholders. In addition, the
Special  Servicer may accept a lower offer if it determines,  in accordance with
the  Servicing  Standard,  that  acceptance  of such offer  would be in the best
interests of the  Certificateholders  (for  example,  if the  prospective  buyer
making the lower offer is more likely to perform its  obligations,  or the terms
offered by the  prospective  buyer  making the lower offer are more  favorable),
provided  that the offeror is not an Affiliate of the Special  Servicer.  In the
event that the Special Servicer determines with respect to any REO Property that
the offers being made with respect  thereto are not in the best interests of the
Certificateholders and that the end of the period referred to in Section 3.17(a)
with respect to such REO Property is  approaching,  the Special  Servicer  shall
seek an  extension of such period in the manner  described  in Section  3.17(a);
provided,  however,  that the  Special  Servicer  shall  use its  best  efforts,
consistent  with the Servicing  Standard,  to sell any REO Property prior to the
Rated Final Distribution Date.

     (b) In  determining  whether any offer  received from an Interested  Person
represents  a fair price for any  Specially  Serviced  Mortgage  Loan or any REO
Property,  the Trustee may  conclusively  rely on the opinion of an  Independent
appraiser or other  Independent  expert in real estate  matters  retained by the
Trustee at the  expense of the Trust  Fund.  In  determining  whether  any offer
constitutes  a fair price for any  Specially  Serviced  Mortgage Loan or any REO
Property,  the Special  Servicer  (if the highest  offeror is not an  Interested
Person) or the  Trustee  (or, if  applicable,  such  appraiser)  shall take into
account,  and any  appraiser  or other  expert in real estate  matters  shall be
instructed to take into account, as applicable, among other factors, any Updated
Appraisal previously  obtained,  the period and amount of any delinquency on the
affected   Specially   Serviced   Mortgage   Loan,   the   physical   (including
environmental) 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 time period specified in Section 3.17(a).

     (c) Subject to the provisions of Section 3.17,  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 Specially  Serviced
Mortgage Loan or REO Property,  including the collection of all amounts  payable
in connection  therewith.  Any sale of a Specially Serviced Mortgage Loan or any
REO Property shall be without recourse to, or representation or warranty by, the
Trustee, the Fiscal Agent, the Depositor,  the 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 such  sale is
consummated in accordance with the duties of the Special Servicer, the Servicer,
the  Depositor,  the Fiscal Agent and the Trustee  pursuant to the terms of this
Agreement, no such Person who so performed shall have any liability to the Trust
Fund or any  Certificateholder  with  respect  to the  purchase  price  therefor
accepted by the Special Servicer or, if the offeror is an Interested Person, the
Servicer (or the Trustee, if the Servicer is an offeror).

     (d) The Special  Servicer  shall file  information  returns  regarding  the
abandonment or foreclosure of Mortgaged  Properties with the IRS at the time and
in the manner required by the Code.

     (e) The  proceeds of any sale after  deduction of the expenses of such sale
incurred in connection therewith shall be promptly,  and in any event within one
Business Day following receipt thereof,  deposited in the Collection  Account in
accordance with Section 3.05(a)(iv).

     SECTION 3.19. Additional  Obligations of the Servicer and Special Servicer;
                   Inspections.

     (a) The Servicer (or, with respect to Specially Serviced Mortgage Loans and
REO  Properties,  the Special  Servicer)  shall inspect or cause to be inspected
(each at its own expense,  respectively)  each Mortgaged  Property at such times
and in such manner as are  consistent  with the Servicing  Standard,  but in any
event shall inspect each Mortgaged Property with an Allocated Loan Amount of (A)
$2,000,000 or more at least once every 12 months and (B) less than $2,000,000 at
least  once every 24 months,  in each case  commencing  in June 1998 (or at such
lesser  frequency as each Rating  Agency shall have  confirmed in writing to the
Servicer,  will not result a downgrade,  qualification or withdrawal of the then
current  ratings  assigned  to any  Class  of the  Certificates)  and (C) if the
Mortgage Loan (i) becomes a Specially  Serviced  Mortgage Loan,  (ii) has a Debt
Service  Coverage  Ratio of less than 1.05  (except with respect to Credit Lease
Loans) or (iii) is delinquent for 60 days,  each Mortgaged  Property  related to
such Specially Serviced Mortgage Loan shall be inspected by the Special Servicer
as soon as  practicable  and  thereafter at least every 12 months for so long as
such condition exists.  The Servicer or Special Servicer,  as applicable,  shall
send to the  Rating  Agencies,  within 20 days of  completion,  each  inspection
report.  For any  Mortgage  Loans  serviced  by the  initial  Servicer,  Special
Servicer may provide  notice to the initial  Servicer of its intent to inspect a
Mortgaged  Property.  Upon  completion  of  the  inspection  of  such  Mortgaged
Property,  Special  Servicer shall provide a copy of the  inspection  report for
such property to the Servicer and Servicer shall be relieved of its then current
obligation to inspect such property.

     The Special Servicer shall have the right to inspect  Mortgaged  Properties
that are on the  Sub-Servicer's  Watch List,  provided that the Special Servicer
notifies the  Sub-Servicer  prior to such  inspection and provides a copy of the
inspection report for such property to the Sub-Servicer.

     (b) With  respect to each  Mortgage  Loan,  the  Servicer  (or the  Special
Servicer,  in the case of a Specially  Serviced Mortgage Loan) shall enforce the
Trustee's  rights with respect to the Manager  under the related Loan  Documents
and  Management  Agreement,  provided,  that,  if such right  accrues  under the
related Loan Documents or Management Agreement only because of the occurrence of
the  related  Anticipated  Repayment  Date,  if any,  the  Servicer  (or Special
Servicer, if applicable) shall irrevocably waive such right with respect to such
date. In the event the Servicer (or Special Servicer, as applicable) is entitled
to terminate  the Manager,  the Servicer (or Special  Servicer,  as  applicable)
shall   promptly   give   notice   to  the   Trustee   (who   shall   copy   the
Certificateholders),  the  Originator,  the  Depositor,  and each Rating Agency.
After receipt of such notice,  the most subordinate  Class of Certificates  then
outstanding shall have the right to recommend termination of the Manager, and if
so, to recommend a Successor Manager (meeting the requirements set forth below).
Certificateholders representing Percentage Interests of greater than 50% of such
subordinate  Class of Certificates  will have ten Business Days from the receipt
of such notice to respond to such notice.  Upon receipt of a  recommendation  to
terminate the Manager and appoint a Successor Manager,  the Servicer (or Special
Servicer, as applicable) shall give notice of such recommendation to the Trustee
(who shall copy the Certificateholders),  and the Servicer (or Special Servicer,
as applicable) shall effect such recommendation unless: (i) within five Business
Days  of the  receipt  of  notice  of  such  recommendation,  Certificateholders
representing   Percentage  Interests  of  greater  than  50%  of  any  Class  of
Certificates  then outstanding  which was assigned a rating by any Rating Agency
on the Closing  Date reject such  proposed  Successor  Manager in which case the
Servicer (or Special Servicer,  as applicable) shall procure a Successor Manager
as set  forth in the  following  sentence;  or (ii)  the  Servicer  (or  Special
Servicer,  as  applicable)  determines  that effecting  such  recommendation  to
terminate  is not  consistent  with the  Servicing  Standard,  the  Servicer (or
Special Servicer, as applicable) shall only effect such recommendation if within
30 days of giving notice to all other Holders the Servicer (or Special Servicer,
as applicable) has not received a rejection of such  recommendation from Holders
of Certificates  representing  Voting Rights of greater than 50% of any Class of
Certificates then outstanding which is assigned a rating by any Rating Agency on
the Closing Date. If the Servicer (or Special Servicer,  as applicable) does not
receive a required  response (or if the response received is inconsistent) or in
the event a  Manager  is  otherwise  terminated  or  resigns  under the  related
Mortgage or  Management  Agreement  and the related  Borrower does not appoint a
Successor Manager,  the Servicer (or Special Servicer,  as applicable) shall use
its best  efforts to retain a Successor  Manager (or the  recommended  Successor
Manager, if any) on terms substantially  similar to the Management Agreement or,
failing  that,  on terms as  favorable  to the Trust Fund as can  reasonably  be
obtained by the Servicer (or Special Servicer, as applicable).  For the purposes
of this paragraph,  a "Successor Manager" shall be reasonably  acceptable to the
Servicer (or Special  Servicer,  as applicable)  and a  professional  management
corporation  or  business  entity  which  (i)  manages,  and is  experienced  in
managing,  other  comparable  commercial  properties,  (ii) will not result in a
downgrade,  qualification  or withdrawal of the then current ratings assigned to
the Certificates by each of Fitch,  DCR, (in the case of DCR, only if the Stated
Principal Balance of such Mortgage Loan exceeds 2% of the total aggregate Stated
Principal  Balance of the Mortgage  Loans)  Moody's and S&P and (iii)  otherwise
satisfies any criteria set forth in the Mortgage and related documents.

     (c) With  respect  to site  inspection  information,  quarterly  and annual
Borrower financial information,  the Sub-Servicer shall make such inquiry of any
Borrower under any related  Mortgage Loan as the Special Servicer may reasonably
request.

     SECTION 3.20. Authenticating Agent.

     The  Trustee  may  appoint  an  Authenticating  Agent  to  execute  and  to
authenticate  Certificates.  The Authenticating  Agent must be acceptable to the
Depositor  and the  Servicer  and  must be a  corporation  organized  and  doing
business  under the laws of the United States of America or any state,  having a
principal  office and place of  business in a state and city  acceptable  to the
Depositor  and the Servicer,  having a combined  capital and surplus of at least
$15,000,000,  authorized  under such laws to do a trust  business and subject to
supervision or examination  by federal or state  authorities.  The Trustee shall
serve as the initial  Authenticating  Agent and the Trustee  hereby accepts such
appointment.

     Any  corporation  into  which  the  Authenticating  Agent  may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which the Authenticating  Agent
shall be party, or any corporation  succeeding to the corporate  agency business
of the  Authenticating  Agent,  shall be the  Authenticating  Agent  without the
execution  or filing of any paper or any  further act on the part of the Trustee
or the Authenticating Agent.

     The Authenticating Agent may at any time resign by giving at least 30 days'
advance  written  notice of  resignation  to the Trustee,  the Depositor and the
Servicer. The Trustee may at any time terminate the agency of the Authenticating
Agent by giving written notice of termination to the  Authenticating  Agent, the
Depositor and the Servicer.  Upon receiving a notice of resignation or upon such
a termination, or in case at any time the Authenticating Agent shall cease to be
eligible in accordance  with the  provisions  of this Section 3.20,  the Trustee
promptly  shall  appoint  a  successor  Authenticating  Agent,  which  shall  be
acceptable  to the  Servicer  and the  Depositor,  and shall mail notice of such
appointment to all Certificateholders.  Any successor  Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers,  duties and  responsibilities  of its predecessor  hereunder,  with like
effect as if  originally  named as  Authenticating  Agent  herein.  No successor
Authenticating  Agent shall be appointed unless eligible under the provisions of
this Section 3.20.

     The Authenticating  Agent shall have no responsibility or liability for any
action  taken by it as such at the  direction  of the  Trustee.  Any  reasonable
compensation paid to the Authenticating Agent shall be an unreimbursable expense
of the Trustee.

     SECTION 3.21. Appointment of Custodians.

     The Trustee may appoint one or more  Custodians to hold all or a portion of
the  Mortgage  Files as agent for the  Trustee,  by  entering  into a  Custodial
Agreement.  The  Trustee  agrees  to  comply  with the  terms of each  Custodial
Agreement and to enforce the terms and provisions  thereof against the Custodian
for the benefit of the Certificateholders.  Each Custodian shall be a depository
institution  subject to supervision by federal or state authority,  shall have a
combined  capital  and surplus of at least  $10,000,000,  shall have a long-term
debt rating of at least "BBB" from Fitch,  DCR and S&P and "Baa2" from  Moody's,
unless the Trustee shall have  received  prior  written  confirmation  from each
Rating Agency that the appointment of such Custodian would not cause such Rating
Agency to withdraw,  qualify or downgrade any of its then-current ratings on the
Certificates, and shall be qualified to do business in the jurisdiction in which
it holds any Mortgage  File.  Each  Custodial  Agreement  may be amended only as
provided in Section  10.07.  Any reasonable  compensation  paid to the Custodian
shall be an  unreimbursable  expense of the Trustee.  The Trustee shall serve as
the initial Custodian.  The Custodian shall maintain a fidelity bond in the form
and amount that are customary for securitizations  similar to the securitization
evidenced by this Agreement, with the Trustee named as loss payee. The Custodian
shall be deemed to have  complied with this  provision if one of its  respective
Affiliates  has such  fidelity  bond coverage and, by the terms of such fidelity
bond, the coverage afforded  thereunder  extends to the Custodian.  In addition,
the Custodian  shall keep in force during the term of this Agreement a policy or
policies of insurance  covering  loss  occasioned by the errors and omissions of
its officers and employees in connection with its  obligations  hereunder in the
form  and  amount  that  are  customary  for  securitizations   similar  to  the
securitization  evidenced  by this  Agreement,  with the  Trustee  named as loss
payee.  All  fidelity  bonds and  policies  of errors  and  omissions  insurance
obtained  under this  Section  3.21 shall be issued by a Qualified  Insurer,  or
shall be otherwise acceptable to the Rating Agencies.

Servicer, the Special Servicer shall prepare and execute a Form 12b-25 under the
Exchange Act and shall deliver an electronic version of such form to the Trustee

     (c) The  Servicer,  or the  Special  Servicer  with  respect  to  Specially
Serviced  Mortgage Loans shall,  in accordance  with such  reasonable  rules and
procedures as it may adopt (which may include the requirement  that an agreement
that  provides  that such  information  shall be used  solely  for  purposes  of
evaluating the investment characteristics of the Certificates be executed to the
extent the Servicer,  or the Special Servicer with respect to Specially Serviced
Mortgage  Loans,  deems such action to be necessary or  appropriate),  also make
available  any  additional  information  relating  to the  Mortgage  Loans,  the
Mortgaged Properties or the Borrowers,  for review by the Depositor,  the Rating
Agencies and any other  Persons to whom the  Servicer,  or the Special  Servicer
with respect to Specially  Serviced  Mortgage Loans believes such  disclosure is
appropriate,  in each  case  except  to the  extent  doing so is  prohibited  by
applicable law or by any related Loan Documents related to a Mortgage Loan.

     (d) The Servicer  and the Special  Servicer  shall make  available at their

as applicable  and (iv) any and all officer's  certificates  and other  evidence
delivered  to  the  Trustee  and  the   Depositor  to  support  the   Servicer's
determination  that any  Advance  was,  or if made  would  be, a  Nonrecoverable
Advance.  Copies of any and all of the foregoing  items shall be available  from
the  Servicer  or the  Special  Servicer,  as  applicable,  or the  Trustee,  as
applicable, upon request.

     (e)  Notwithstanding  the  obligations  of the  Servicer  set  forth in the
preceding  provisions  of this  Section  3.22,  the  Servicer  may  withhold any
information  not yet  included  in a Form  8-K  filed  with  the  Commission  or
otherwise  made  publicly  available  with  respect to which the  Trustee or the
Servicer has determined that such withholding is appropriate.

     (f) Notwithstanding  any provisions in this Agreement to the contrary,  the
Trustee  shall not be required to review the content of any  Exchange Act Report
for compliance  with applicable  securities  laws or regulations,  completeness,
accuracy or otherwise,  and the Trustee shall have no liability  with respect to
any   Exchange   Act  Report   filed  with  the   Commission   or  delivered  to
Certificateholders.  None of the Servicer,  the Special Servicer and the Trustee
shall  be  responsible  for the  accuracy  or  completeness  of any  information
supplied by a Borrower or a third party for  inclusion in any Form 8-K, and each

Trust Fund against any loss,  liability or expense  incurred in connection  with
any legal action  relating to any statement or omission or alleged  statement or
omission therein.

     SECTION 3.23. Lock-Box Accounts, Cash Collateral Accounts,  Escrow Accounts
                   and Reserve Accounts.

     The Servicer  shall  administer  each  Lock-Box  Account,  Cash  Collateral

     SECTION 3.24. Property Advances.

     (a) The  Servicer  (or,  to the extent  provided  in Section  3.24(b),  the
Trustee or the Fiscal Agent or to the extent  specifically  provided for in this
Agreement,  the Special Servicer) shall make any Property Advances as and to the
extent  otherwise  required  pursuant  to the  terms  hereof.  For  purposes  of
distributions to  Certificateholders  and compensation to the Servicer,  Special
Servicer or Trustee,  Property  Advances shall not be considered to increase the
principal balance of any Mortgage Loan,  notwithstanding  that the terms of such
Mortgage Loan so provide.

     (b) The  Servicer  shall notify the Trustee and the Fiscal  Agent,  and the
Special Servicer shall notify the Servicer, the Trustee and the Fiscal Agent, in
writing promptly upon, and in any event within one Business Day after,  becoming
aware that it will be unable to make any  Property  Advance  required to be made
pursuant to the terms hereof,  and in connection  therewith,  shall set forth in
such notice the amount of such Property  Advance,  the Person to whom it will be
paid, and the circumstances and purpose of such Property Advance,  and shall set
forth  therein  information  and  instructions  for the payment of such Property
Advance,  and,  on the date  specified  in such  notice for the  payment of such
Property  Advance,  or, if the date for payment has passed or if no such date is
specified, then within five Business Days following such notice, the Trustee (or
with respect to a Property Advance required to be made by the Special  Servicer,
the  Servicer,  and if the  Servicer  so fails,  the  Trustee),  subject  to the
provisions of Section 3.24(c),  shall pay the amount of such Property Advance in
accordance with such information and instructions.  If the Trustee fails to make
any Property  Advance  required to be made under this Section  3.24,  the Fiscal
Agent, subject to the provisions of Section 3.24(c),  shall make such Advance on
the same day the  Trustee  was  required  to make  such  Property  Advance  and,
thereby, the Trustee shall not be in default under this Agreement.

     (c) None of the  Servicer,  the  Trustee,  the Fiscal  Agent or the Special
Servicer  shall be obligated to make a Property  Advance as to any Mortgage Loan
or REO Property if the  Servicer,  the Trustee,  the Fiscal Agent or the Special
Servicer,  as applicable,  determines that such Advance will be a Nonrecoverable
Advance.  The Trustee and the Fiscal  Agent (or the  Servicer  with respect to a
Property Advance required to be made by the Special  Servicer) shall be entitled
to rely, conclusively, on any determination by the Servicer or Special Servicer,
as  applicable,  that a Property  Advance,  if made,  would be a  Nonrecoverable
Advance.  The  Trustee and the Fiscal  Agent,  in  determining  whether or not a
Property Advance  previously made is, or a proposed Property  Advance,  if made,
would be, a Nonrecoverable  Advance shall be subject to the standards applicable
to the Servicer hereunder.

     (d) The  Servicer,  the Special  Servicer,  the  Trustee  and/or the Fiscal
Agent,  as  applicable,  shall be  entitled  to the  reimbursement  of  Property
Advances  made  by any of them  to the  extent  permitted  pursuant  to  Section
3.06(ii) of this Agreement, together with any related Advance Interest Amount in
respect of such Property Advances,  and the Servicer and Special Servicer hereby
covenant  and  agree to  promptly  seek and  effect  the  reimbursement  of such
Property  Advances  from  the  related  Borrowers  to the  extent  permitted  by
applicable law and the related Loan Documents.

     SECTION 3.25. Appointment of Special Servicer.

     (a) CRIIMI MAE  Services  Limited  Partnership  is hereby  appointed as the
initial Special Servicer to service each Specially Serviced Mortgage Loan.

     (b)  Certificateholders  representing  greater  than 50% of the  Percentage
Interests of the most subordinate Class of Certificates  outstanding at any time
shall be entitled to remove the Special  Servicer  with or without  cause and to
appoint a successor Special Servicer,  provided that each Rating Agency confirms
to the Trustee in writing that such removal and  appointment,  in and of itself,
would not cause a downgrade,  qualification  or  withdrawal  of the then current
ratings  assigned to any Class of  Certificates.  If there is a Special Servicer
Event of Default, the Special Servicer shall be removed and replaced pursuant to
Sections 7.01(c) and 7.02.

     (c) The  appointment  of any such  successor  Special  Servicer,  shall not
relieve  the  Servicer,  the  Trustee  or the Fiscal  Agent of their  respective
obligations  to make  Advances  as set  forth  herein;  provided,  however,  the
Servicer  shall not be liable for any actions or any inaction of such  successor
Special Servicer. Any termination fee payable to the terminated Special Servicer
(and it is  acknowledged  that  there is no such fee  payable  in the event of a
termination of the Servicer as Special Servicer or in the event of a termination
for  breach  of this  Agreement)  shall  be paid  by the  Certificateholders  so
terminating the Special Servicer and shall not in any event be an expense of the
Trust Fund.

     (d) No termination of the Special  Servicer and  appointment of a successor
Special  Servicer shall be effective  until the successor  Special  Servicer has
assumed all of its  responsibilities,  duties and liabilities hereunder pursuant
to a writing satisfactory to the Trustee and each Rating Agency, as evidenced in
writing,  and the Trustee has  received  written  confirmation  from each Rating
Agency  that such  appointment  would not cause any  Rating  Agency to  qualify,
withdraw or downgrade any of its then current ratings on any  Certificates.  Any
successor  Special  Servicer  shall  make  the  representations  and  warranties
provided for in Section 2.04(a) mutatis mutandis.

     SECTION 3.26.  Transfer of Servicing Between Servicer and Special Servicer;
                    Record Keeping.

     (a) Upon determining that any Mortgage Loan has become a Specially Serviced
Mortgage  Loan,  the Servicer  shall  immediately  give notice  thereof,  to the
Special  Servicer and shall use its best efforts to provide the Special Servicer
with  all   information,   documents  (but  excluding  the  original   documents
constituting   the  Mortgage  File)  and  records   (including   records  stored
electronically  on computer tapes,  magnetic discs and the like) relating to the
Mortgage Loan and reasonably  requested by the Special  Servicer to enable it to
assume its duties  hereunder  with  respect  thereto  without  acting  through a
sub-servicer.  The  Servicer  shall  use its best  efforts  to  comply  with the
preceding  sentence  within five  Business  Days of the date such  Mortgage Loan
became a Specially Serviced Mortgage Loan and in any event shall continue to act
as 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  (provided  that receipt of copies of all
documents in the Mortgage File shall suffice for such purpose).  With respect to
each Mortgage Loan that becomes a Specially Serviced Mortgage Loan, the Servicer
shall instruct the related Borrower to continue to remit all payments in respect
of such  Mortgage  Loan to the Servicer.  The Servicer or Special  Servicer,  as
applicable, may agree that, notwithstanding the preceding sentence, with respect
to each  Mortgage  Loan that  became a Specially  Serviced  Mortgage  Loan,  the
Servicer shall instruct the related Borrower to remit all payments in respect of
such Mortgage Loan to the Special  Servicer,  provided that the payee in respect
of such payments shall remain the Servicer.  The Special Servicer shall remit to
the Servicer any such payments received by it pursuant to the preceding sentence
within one Business Day of receipt.  The Servicer  shall  forward any notices it
would  otherwise send to the Borrower of a Specially  Serviced  Mortgage Loan to
the Special Servicer who shall send such notice to the related Borrower.

     Upon  determining that no event has occurred and is continuing with respect
to a Mortgage  Loan that causes such  Mortgage  Loan to be a Specially  Serviced
Mortgage Loan, the Special Servicer shall immediately give notice thereof to the
Servicer,  and upon giving such notice,  such  Mortgage Loan shall cease to be a
Specially  Serviced  Mortgage Loan in  accordance  with the first proviso of the
definition  of  Specially   Serviced  Mortgage  Loan,  the  Special   Servicer's
obligation to service such Mortgage Loan shall  terminate and the obligations of
the Servicer to service and  administer  such  Mortgage  Loan as a Mortgage Loan
that is not a Specially Serviced Mortgage Loan shall resume. In addition, if the
related  Borrower  has been  instructed,  pursuant  to the last  sentence of the
preceding  paragraph,  to make  payments  to the  Special  Servicer,  upon  such
determination, the Special Servicer shall instruct the related Borrower to remit
all payments in respect of such Specially Serviced Mortgage Loan directly to the
Servicer.

     (b) In servicing any Specially Serviced Mortgage Loan, the Special Servicer
shall  provide  to the  Trustee  originals  of  documents  included  within  the
definition of "Mortgage File" for inclusion in the related Mortgage File (to the
extent such documents are in the possession of the Special  Servicer) and copies
of any additional  related Mortgage Loan information,  including  correspondence
with the related  Borrower,  and the Special  Servicer  shall  promptly  provide
copies of all of the foregoing to the Servicer and the  Sub-Servicer  as well as
copies of any analysis or internal  review prepared by or for the benefit of the
Special Servicer.

     (c) Not  later  than the  Business  Day  preceding  each  date on which the
Servicer is required to furnish a report under  Section  3.13(a) to the Trustee,
the Special  Servicer shall deliver to the Trustee,  with a copy to the Servicer
and the  Sub-Servicer,  a written  statement  describing,  on a Mortgage Loan by
Mortgage  Loan basis (for all Mortgage  Loans for which the Special  Servicer is
collecting the payments  thereon),  (i) the amount of all payments on account of
interest  received on each Specially  Serviced  Mortgage Loan, the amount of all
payments  on account of  principal,  including  Principal  Prepayments,  on each
Specially  Serviced Mortgage Loan, the amount of Net Insurance  Proceeds and Net
Liquidation  Proceeds received with respect to each Specially  Serviced Mortgage
Loan, and the amount of net income or net loss, as determined from management of
a trade or business on, the furnishing or rendering of a  non-customary  service
to the tenants of, or the receipt of any rental income that does not  constitute
Rents from Real  Property  with  respect to the REO  Property  relating  to each
applicable  Specially  Serviced  Mortgage Loan, in each case in accordance  with
Section  3.17 and (ii) such  additional  information  relating to the  Specially
Serviced Mortgage Loans as the Servicer or Trustee reasonably requests to enable
it to perform its duties under this Agreement.

     (d)  Notwithstanding  the provisions of the preceding  subsection  (c), the
Servicer  shall  maintain  ongoing  payment  records with respect to each of the
Specially  Serviced  Mortgage Loans and shall provide the Special  Servicer with
any  information  reasonably  required  by the  Special  Servicer to perform its
duties under this  Agreement.  The Special  Servicer  shall provide the Servicer
with any information  reasonably  required by the Servicer to perform its duties
under this Agreement.

     SECTION 3.27. Interest Reserve Account.

     (a) On each  Servicer  Remittance  Date  relating to any  Interest  Accrual
Period  ending in any February and on any Servicer  Remittance  Date relating to
any Interest  Accrual  Period ending in any January which occurs in a year which
is not a leap year, the Servicer  shall remit to the Trustee,  in respect of the
Interest Reserve Loans, for deposit into the Interest Reserve Account, an amount
equal to one day's  interest  (assuming a 360-day year) on the Stated  Principal
Balance of the Interest  Reserve Loans as of the Due Date occurring in the month
preceding the month in which such Servicer Remittance Date occurs at the related
Net Mortgage  Pass-Through  Rate,  to the extent a full  Monthly  Payment or P&I
Advance is made in respect  thereof (all amounts so deposited in any consecutive
January and February, "Withheld Amounts").

     (b) On each Servicer Remittance Date occurring in March, the Servicer shall
instruct  the Trustee to withdraw  from the Interest  Reserve  Account an amount
equal to the Withheld Amounts from the preceding  January,  if any, and February
and deposit such amount into the Distribution Account.

     SECTION 3.28. Limitations on and Authorizations of the Servicer and Special
                   Servicer with Respect to Certain Mortgage Loans.

     (a) Prior to taking any action with  respect to a Mortgage  Loan secured by
Mortgaged  Properties  located in a "one-action"  state, the Servicer or Special
Servicer, as applicable, shall consult with legal counsel, the fees and expenses
of which shall be an expense of the Trust Fund.

     (b) With respect to any Mortgage Loan which  permits the related  Borrower,
with  the  consent  or  grant  of a waiver  by  mortgagee,  to incur  additional
indebtedness,  to grant additional  encumbrances  against the related  Mortgaged
Property or to amend or modify the related Borrower's  organizational  documents
or the organizational  documents of the owner of the Borrower, then the Servicer
or the Special  Servicer,  as applicable may only either consent to such action,
or grant a waiver with respect thereto, if the Servicer or the Special Servicer,
as  applicable  determines  that such consent or waiver is likely to result in a
greater  recovery on a present value basis  (discounted at the related  Mortgage
Rate) than would not  consenting  to such action and the Servicer or the Special
Servicer first obtains  written  confirmation  from each Rating Agency that such
consent or grant of a waiver would not, in and of itself, result in a downgrade,
qualification  or withdrawal of any of the then current ratings  assigned to the
Certificates.

     (c) With respect to the Mortgage Loans that require the related Borrower to
pay Rating  Agency  monitoring  or review fees,  the Servicer  shall enforce the
obligation of the related  Borrowers to pay Rating  Agency  monitoring or review
fees and shall  remit such fees from the  related  Cash  Collateral  Account for
payment of such fees to the  applicable  Rating  Agencies.  The  Servicer  shall
receive bills from the Rating Agencies for monitoring,  review and  surveillance
of the  Certificates and the Mortgage Loans on behalf of NACC and shall promptly
notify and send such bills to NACC,  Attention:  Marlyn A.  Marincas.  NACC will
notify each Rating  Agency to bill NACC for such services and to send such bills
to the Servicer.  The Servicer shall notify NACC of the portion of the bill that
it has paid from  funds  collected  from such  Borrowers  and NACC will pay such
portion of the bill not paid from funds provided by the applicable Borrowers (as
described in this section (c)).

     (d) With respect to all Mortgage  Loans that provide that the holder of the
related  Note  may  apply  amounts  received  thereunder   (including,   without
limitation, Liquidation Proceeds) against principal, interest and any other sums
due in the order as the holder shall determine, the Servicer shall apply amounts
received in respect of such  Mortgage  Loans (i) first to  interest  (other than
Excess  Interest or Default  Interest) due  thereunder;  (ii) next to principal;
(iii) next to default interest due thereunder;  (iv) next to Prepayment Premiums
(except  for  Return of Fee  Amounts)  due  thereunder;  (v) then to any  Excess
Interest due thereunder; (vi) then to reimburse any litigation or other expenses
incurred in  collecting  any such amounts  received in respect of such  Mortgage
Loan;  (vii) then to any Return of Fee Amounts due thereunder and (viii) finally
to any other sums due thereunder.

     (e) With  respect to the  Mortgage  Loans that have  Anticipated  Repayment
Dates,   the   Servicer   (including   the   Servicer  in  its   capacity  as  a
Certificateholder,  if applicable),  shall not take any enforcement  action with
respect  to the  payment  of  Excess  Interest  or  principal  in  excess of the
principal  component of the constant  Monthly  Payment,  other than requests for
collection, until the maturity date of the related Mortgage Loan.

     (f) To the extent not inconsistent with the related Mortgage Loan,  neither
the Servicer  nor the Special  Servicer  shall  consent to a change of franchise
affiliation  with  respect to a  Mortgaged  Property  unless it obtains  written
confirmation  from Fitch,  DCR, S&P and Moody's that such consent  would not, in
and of itself,  result in a downgrade,  qualification  or withdrawal of the then
current ratings assigned to the Certificates.

     (g)   With   respect   to  any   Mortgage   Loan   secured   by  a   senior
housing/healthcare  facility, the Special Servicer shall hire a consultant which
is  experienced  in the  operation  of such  facilities  in the event  that such
Mortgage Loan becomes a Specially Serviced Mortgage Loan.

     (h) With  respect to the  Mortgage  Loans that have  Anticipated  Repayment
Dates, the Servicer shall be permitted,  in its discretion,  to waive all or any
accrued  Excess  Interest if, prior to the related  maturity  date,  the related
Borrower has  requested  the right to prepay the Mortgage  Loan in full together
with  all  payments  required  by the  Mortgage  Loan in  connection  with  such
prepayment except for all or a portion of accrued Excess Interest, provided that
the Servicer's  determination to waive the right to such accrued Excess Interest
is reasonably  likely to produce a greater  payment to  Certificateholders  on a
present  value basis than a refusal to waive the right to such Excess  Interest.
Any such waiver shall not be effective  until such  prepayment is tendered.  The
Servicer will have no liability to the Trust Fund, the Certificateholders or any
other person so long as such determination is based on such criteria. Other than
pursuant to Section 3.30, the Special  Servicer shall have no right to waive the
payment of Excess  Interest  under the  circumstances  described in this Section
3.28(h).

     (i)  With  respect  to the  Mortgage  Loans  that  (i)  require  earthquake
insurance,  or (ii) (A) at the date of  origination  were  secured by  Mortgaged
Properties on which the related Borrower maintained earthquake insurance and (B)
have  provisions  which  enable the  Servicer to continue to require the related
Borrower  to maintain  earthquake  insurance,  the  Servicer  shall  require the
related Borrower to maintain such insurance in the amount, in the case of clause
(i),  required by the  Mortgage  Loan and in the  amount,  in the case of clause
(ii),  maintained at  origination,  in each case, to the extent such amounts are
available at commercially  reasonable  rates. Any  determination by the Servicer
that such insurance is not available at commercially  reasonable  rates shall be
subject to  confirmation by Fitch that such  determination  not to purchase such
insurance  will not result in a downgrade,  qualification  or  withdrawal of the
then current ratings assigned to the Certificates rated by Fitch.

     (j) The Servicer shall send written notice to each Borrower and the related
Manager and clearing bank that, if applicable,  the Servicer  and/or the Trustee
has been appointed as the "Designee" of the "Lender" under any related  Lock-Box
Agreement.

     (k) Each of the  Servicer  and the Special  Servicer  hereby  agrees to use
efforts  consistent  with the  Servicing  Standard  to abide  by the  terms  and
conditions  precedent to payment of claims under any Lease Enhancement  Policies
and Residual  Value  Policies and to use efforts  consistent  with the Servicing
Standard to take all such action as may be required to comply with the terms and
provisions of such policies in order to maintain, in full force and effect, such
Lease  Enhancement  Policies and Residual  Value  Policies,  including,  but not
limited to, (i) notifying  the related  insurer in writing as soon as reasonably
practicable,  but in any event within the time period  required  under the Lease
Enhancement Policy,  after the Servicer or the Special Servicer,  as applicable,
first  receives  written  notification  of the  commencement  of a  condemnation
proceeding with respect to any Mortgaged Property covered by a Lease Enhancement
Policy, (ii) notifying the insurer in writing as soon as reasonably practicable,
but in any event  within the time period  required  under the Lease  Enhancement
Policy,  after the  Servicer  or the  Special  Servicer,  as  applicable,  first
receives written  notification of the occurrence of physical damage with respect
to any such  Mortgaged  Property  that may be covered  by such  policy and (iii)
notifying the insured as soon as reasonably practicable, but in any event within
the time period required under the Lease Enhancement Policy,  after the Servicer
or the Special Servicer,  as applicable,  first receives written notification of
termination  or rent  abatement by the related credit tenant with respect to any
credit lease  underlying  a Mortgaged  Property  covered by a Lease  Enhancement
Policy.  In addition to complying with all  conditions to coverage,  each of the
Servicer  and the  Special  Servicer  hereby  agrees  that it will  use  efforts
consistent  with the  Servicing  Standard to take any and all  actions  required
under the Lease  Enhancement  Policy or Residual Value Policy in connection with
any claim,  including (i) the timely  presentation of a proof of loss containing
all  required  information,  (ii) the  prosecution  of all claims  relating to a
casualty or  condemnation,  consistent with the Servicing  Standard,  which will
maximize any  recoveries or awards from sources other than the insurer under the
Lease  Enhancement  Policy,  (iii) providing  reasonable access to any Mortgaged
Property  (but only to the  extent  such  access is  available  pursuant  to the
related Loan Documents,  applicable law and the related Credit Lease),  (iv) the
providing of any other notices required under the Lease Enhancement  Policies or
Residual  Value  Policy in a timely  fashion  and any other  actions  which will
maximize any recoveries under the Lease Enhancement Policies, and (v) the timely
submission of claims under the Lease Enhancement Policy or Residual Value Policy
to the extent the Servicer or the Special Servicer, as applicable, determines in
accordance with the Servicing Standard that any such claim would not be excluded
under the terms of the Lease  Enhancement  Policy or Residual Value Policy.  Any
and all amounts  collected  under a Lease  Enhancement  Policy or Residual Value
Policy shall be  immediately  deposited in the  Collection  Account,  subject to
withdrawal as provided herein.

     (l) For any  Specially  Serviced  Mortgage  Loan and with respect to which,
under the  terms of the  related  Loan  Documents,  the  mortgagee  may,  in its
discretion,  apply Insurance Proceeds,  condemnation awards or escrowed funds to
the  prepayment  of such loan prior to the  expiration  of the related  Lock-out
Period,  the Special  Servicer  may only make such a  prepayment  if the Special
Servicer has first  received the prior  written  consent of the Servicer  (which
consent will be given or withheld in accordance with the Servicing Standard).

     (m) If any Mortgage Loan provides that the "Lender" with respect thereto is
required  to  purchase  U.S.  government  obligations  on behalf of the  related
Borrower in connection  with any  defeasance  of the related Note,  the Servicer
shall (upon receipt of sufficient funds from the related Borrower) purchase such
obligations  and  effectuate  such  defeasance,  at the Borrower's  expense,  in
accordance  with the provisions of the related Loan  Documents,  consistent with
the Servicing Standard.

     (n) The Servicer (together with its employees, officer and directors) shall
not utilize the proprietary and nonpublic  information  that it becomes aware of
in servicing the Mortgage Loans to render advice in connection with, solicit, or
otherwise  participate  in the  refinancing  of any Mortgage  Loans  (whether at
maturity or otherwise,  unless the Mortgage Loan Seller confirms in writing that
it will not pursue the  refinancing  of such  Mortgaged  Property).  Neither the
Servicer nor the Special  Servicer shall make its Mortgage Loan Servicing System
available to the  Servicer's  Affiliates or the Special  Servicer's  Affiliates,
respectively,  engaged in the commercial mortgage  origination  business for the
purpose  of  refinancing  a  Mortgage  Loan  prior  to or at its due  date.  The
provisions of this Section  3.28(n) shall not be applicable to  Sub-Servicer  in
its capacity as subservicer nor in the capacity as a successor Servicer.

     (o) The  Servicer  shall  administer  the Westin  Casuarina  Resort Loan in
accordance with the Westin Casuarina Co-Lender Agreement, including making a pro
rata share of any  Property  Advances  pursuant to Section 3 of such  agreement,
unless the servicer under Series 1997-D5  determines that such Advance will be a
Nonrecoverable Advance.

     (p) With  respect to each Credit  Lease Loan for which a Lease  Enhancement
Policy has been obtained, to the extent permitted in the Mortgage Loan Documents
in the event of a condemnation  which results in a partial  abatement of rent by
the related  Borrower,  periodic  payments (but not lump sum payments)  from the
Lease  Enhancement  Policy shall be made to the lock-box account related to such
Credit Lease Loan, and the Servicer shall apply such amounts to the next Monthly
Payment.

     (q) With respect to any Credit Lease Loan as to which the insurer under the
related casualty and condemnation lease enhancement insurance policy has invoked
the  arbitration  provision  under  such  policy  with  respect  to any  payment
thereunder, the Servicer or Special Servicer, with respect to Specially Serviced
Mortgage  Loans,  shall hold any  payment  required  to be made by such  insurer
pending the outcome of such  arbitration  in a  segregated  account (the "Credit
Lease Insurance  Arbitration  Account",  which shall be an Eligible Account, and
shall make a P&I Advance  (subject to a  nonrecoverability  determination)  with
respect  to the  amount  of such  payment.  Upon the  final  resolution  of such
arbitration,  (a) if  favorable  to the Trust Fund,  amounts in the Credit Lease
Insurance  Arbitration Account shall,  together with interest earned thereon, be
remitted to the  Servicer  and,  (b) if  favorable  to the insurer (an  "Adverse
Resolution"),  shall be remitted to the insurer for payment in  accordance  with
the  determination  of the arbitration  panel. To the extent of any such Adverse
Resolution,  and to the extent there are not other sources of recovery,  (a) P&I
Advances  made pursuant to this Section  3.28(q) shall be deemed  Nonrecoverable
Advances, and (b) the amount of any such award to the insurer shall be allocated
as a Realized Loss as provided in this Agreement.

     (r) Without limiting the obligations of the Servicer hereunder with respect
to the enforcement of a Borrower's  obligations  under the related Mortgage Loan
Documents,  the  Servicer  agrees that it shall  enforce the  provisions  of the
Mortgage Loan Documents with respect to the collection of Prepayment Premiums.

     (s) In the event that a Rating Agency shall charge a fee in connection with
providing  confirmation  hereunder that a proposed action will not result in the
downgrade,  withdrawal,  or qualification of any rating assigned to any Class of
Certificates, the Servicer shall require the related Borrower to pay such fee to
the full extent permitted under the applicable Mortgage Loan Documents.

     (t) The Servicer  shall  convene  dial-in  conference  calls on a quarterly
basis  for the  purpose  of  providing  investors  in the  Certificates  with an
opportunity to discuss pool and loan  performance  issues,  beginning in October
1998.

     (u) To the extent not inconsistent with the related Mortgage Loan,  neither
the Servicer nor the Special  Servicer  shall  consent to a  replacement  of the
related property manager with respect to a Mortgaged  Property unless it obtains
written  confirmation  from Fitch,  DCR, S&P and Moody's that such consent would
not, in and of itself, result in a downgrade, qualification or withdrawal of the
then current ratings assigned to the Certificates provided, however, that if the
Stated Principal Balance of such Mortgage Loan is less than the lesser of (x) 2%
of the total aggregate Stated  Principal  Balances of the Mortgage Loans and (y)
$30,000,000, and is not one of the ten largest Mortgage Loans in the Trust Fund,
such written confirmation shall not be required from DCR.

     (v) To the extent not inconsistent with the related Mortgage Loan,  neither
the Servicer nor the Special  Servicer  shall consent to a transfer of ownership
interest in any  Borrower or  beneficial  owner of  Borrower  with  respect to a
Mortgaged  Property unless it obtains written  confirmation from Fitch, DCR, S&P
and  Moody's  that  such  consent  would  not,  in and of  itself,  result  in a
downgrade,  qualification  or withdrawal of the then current ratings assigned to
the  Certificates,  provided,  however,  that if the Stated Principal Balance of
such  Mortgage  Loan is less than the  lesser  of (x) 2% of the total  aggregate
Stated Principal Balances of the Mortgage Loans and (y) $30,000,000,  and is not
one  of the  ten  largest  Mortgage  Loans  in  the  Trust  Fund,  such  written
confirmation shall not be required from any of the Rating Agencies.

     (w) To the extent not  inconsistent  with the related  Mortgage  Loan,  the
Servicer shall  maintain all reserve  accounts and cash  collateral  accounts as
Eligible  Accounts  and  shall  invest  funds  in  such  accounts  in  Permitted
Investments.

     (x) To the extent not  inconsistent  with the related  Mortgage  Loan,  the
Servicer shall, as a condition to granting consent to any material alteration of
a  Mortgaged  Property  require any such  Borrower to post cash  security in the
amount of 125% of the projected cost of such alteration, provided, however, that
if the Stated Principal Balance of such Mortgage Loan is less than the lesser of
(x) 2% of the total aggregate  Stated  Principal  Balances of the Mortgage Loans
and (y)  $30,000,000,  and is not one of the ten largest  Mortgage  Loans in the
Trust Fund, such deposit shall not be required.  A material  alteration shall be
an alteration  where the  projected  cost of such  alteration  exceeds 5% of the
Stated Principal Balance of such Mortgage Loan.

     (y) No more than 90 days  prior to the  Maturity  Date with  respect to the
Mortgage Loan  identified as the Research Park loan (the  "Research Park Loan"),
the Servicer shall request written  confirmation from the related Borrower as to
whether such Borrower  intends to pay the outstanding  principal  balance of the
Research Park Loan on its Maturity Date.  The Servicer shall promptly  provide a
copy of the related Borrower's response to such request to the Special Servicer.
In the event the Borrower fails to respond to such inquiry,  or responds that it
does not intend to pay the  outstanding  principal  balance of the Research Park
Loan,  such loan  shall be deemed a  Specially  Serviced  Mortgage  Loan and the
servicing of such loan shall be  transferred to the Special  Servicer.  If after
receipt of a response from such Borrower, the Special Servicer determines that a
default on the related  Maturity  Date is  reasonably  foreseeable,  the Special
Servicer shall notify the Borrower  thereunder  that the Special  Servicer would
agree to extend the Maturity  Date of the Research  Park Loan until the Due Date
that is at least 360  months  from the date of the  origination  of such Loan if
such Borrower  agrees that the terms of the Research Park Loan shall be modified
to provide for terms  substantially  similar to those  provided  for in Mortgage
Loans for which there is an Anticipated Repayment Date (including the payment of
Excess  Interest,  at a  rate  not to  exceed  the  related  Default  Rate,  and
application  of excess  cash  flow from the  Mortgaged  Property  to prepay  the
Research Park Loan).

     (z) Pursuant to the  provisions of any Mortgage Loan which provides for the
removal of a property manager, any calculation of Debt Service Coverage Ratio by
the Servicer  shall use the Mortgage  Rate,  and not the Revised  Mortgage Rate,
regardless of the rate in effect at the time of such calculation.

     (aa)The  Servicer shall not remove any property  manager solely because any
Mortgage Loan has reached its  Anticipated  Repayment  Date and there remains an
outstanding principal balance on such Mortgage Loan.

     (bb)With  respect to the  Mortgage  Loan  known as Bristol I, the  Servicer
shall not  exercise  discretion  with  respect to any request  for  substitution
pursuant to Section 2.4.4 of the related Loan Agreement.  The Borrower shall not
be permitted to substitute any of the Mortgaged Properties unless the conditions
to such  substitution  set forth in Sections  2.4.1 and 3.2 of the related  Loan
Agreement have been  satisfied and the Servicer  receives  written  confirmation
from Fitch,  DCR,  S&P and Moody's that such  substitution  would not, in and of
itself,  result in a downgrade,  qualification or withdrawal of the then current
ratings  assigned to the  Certificates.  The  Borrower  shall be permitted to so
substitute  provided that such conditions are met and that the Servicer receives
such written confirmation. Prior to the occurrence of any such substitution, the
Servicer  shall first  provide to the Special  Servicer a copy of all  materials
provided by such borrower to evidence that related conditions have been met, and
then  provide the Special  Servicer an  opportunity  during a four  Business Day
period  prior  to any  such  substitution  to  confer  with  them as to  whether
applicable conditions have been met (it being understood that the Servicer shall
not have any obligation to follow any  instructions or directions  given to them
by the Special Servicer with respect thereto).

     SECTION 3.29. Intentionally left Blank.

     SECTION 3.30. Modification, Waiver, Amendment and Consents.

     (a) The Special Servicer may, consistent with the Servicing Standard, agree
to the  modification,  waiver or  amendment  of any term of a  Mortgage  Loan in
accordance with this Section 3.30.

     (b) The Special Servicer may, consistent with the Servicing Standard, agree
to any  modification,  waiver  or  amendment  of any term of,  forgive  or defer
interest on and principal of, and/or add collateral  for, any Mortgage Loan with
the consent of Certificateholders  representing 100% of the Percentage Interests
of the most subordinate  Class of Certificates  then  outstanding  determined as
provided  below,  subject,  however,  to  each  of  the  following  limitations,
conditions and restrictions:

       (i)    a material  default on such  Mortgage Loan has occurred or, in the
              Special Servicer's  reasonable and good faith judgment,  a default
              in  respect  of  payment  on  such  Mortgage  Loan  is  reasonably
              foreseeable,  and such  modification,  waiver,  amendment or other
              action is  reasonably  likely to  produce  a greater  recovery  to
              Certificateholders   on  a  present   value  basis  (the  relevant
              discounting of anticipated  collections that will be distributable
              to Certificateholders  will be done at the related Mortgage Rate),
              than would liquidation;

       (ii)   the  Special  Servicer  shall  not  extend  the date on which  any
              Balloon  Payment is scheduled to be due on any Specially  Serviced
              Mortgage Loan except as provided for below;

       (iii)  no reduction of any scheduled  monthly payment of principal and/or
              interest on any Specially  Serviced  Mortgage Loan may result in a
              debt service coverage ratio for such Mortgage Loan of greater than
              1.10 to 1, and the Special  Servicer may only agree to  reductions
              lasting a period of no more than twelve consecutive months and, in
              the  aggregate,  no more  than  three  consecutive  reductions  of
              twelve-months or less each;

       (iv)   the  Special  Servicer  shall not release or  substitute  material
              collateral or release  mortgagors or guarantors except as provided
              in clause (v) below;

       (v)    the  Special  Servicer  may  only  allow a  release  of  Mortgaged
              Properties  through  defeasance or the  assumption of a Borrower's
              obligations with respect to a Mortgage Loan in accordance with the
              terms thereof and the provisions of Section 3.09 hereof;

       (vi)   the  Special  Servicer  may not  forgive  an  aggregate  amount of
              principal  of the  Mortgage  Loans in  excess  of the  Certificate
              Balance  of  the  most  subordinate  Class  of  Certificates  then
              outstanding  (as determined as provided below) minus the aggregate
              of the  greater of (A) any  Appraisal  Reduction  Amounts  and (B)
              Delinquency  Reduction Amounts of each Mortgage Loan that, in each
              case, have not resulted in a Realized Loss;

       (vii)  the  Special  Servicer  shall not permit any  Borrower  to add any
              collateral unless (A) the Special Servicer has first determined in
              accordance   with   the   Servicing   Standard,   based   upon  an
              environmental  assessment  prepared by an  Independent  Person who
              regularly conducts  environmental  assessments,  at the expense of
              the  Borrower,  that such  additional  collateral is in compliance
              with applicable  environmental laws and regulations and that there
              are no  circumstances  or conditions  present with respect to such
              new collateral  relating to the use, management or disposal of any
              hazardous materials for which investigation,  testing, monitoring,
              containment,  clean-up or remediation  would be required under any
              then applicable  environmental laws and/or regulations and (B) the
              Special Servicer has received an Opinion of Counsel at the expense
              of the  Special  Servicer  or the  Borrower  (unless  the  Special
              Servicer owns the most subordinate  Class of Certificates in which
              case,  at the expense of the Trust  Fund),  to the effect that the
              addition of such  collateral  will not cause either the Upper-Tier
              REMIC or the  Lower-Tier  REMIC to fail to  qualify  as a REMIC or
              cause a tax to be  imposed  on the  Trust  Fund  under  the  REMIC
              Provisions; and

       (viii) the Special  Servicer may waive or reduce a Lock-out Period or any
              Prepayment  Premiums  only if the  commencement  of a  foreclosure
              proceeding  with respect to the related  Mortgage Loan is imminent
              and the Special Servicer first receives written  notification from
              the  Servicer  that such  action in the  opinion of the  Servicer,
              consistent  with the  Servicing  Standard  and based  solely  upon
              information  furnished by the Special Servicer without independent
              investigation by the Servicer thereof, is more likely to result in
              a  greater  recovery,  on a  present  value  basis,  than  would a
              foreclosure.

     Notwithstanding  the foregoing,  the Special Servicer shall not be required
to oppose the  confirmation  of a plan in any  bankruptcy or similar  proceeding
involving  a  Borrower  if in  its  reasonable  and  good  faith  judgment  such
opposition would not (i) ultimately prevent the confirmation of such plan or one
substantially  similar and (ii) produce a greater recovery to Certificateholders
on a present value basis.

     For  purposes  of  determining  the amount of  principal  which the Special
Servicer may forgive pursuant to clause (vi) above,  the most subordinate  Class
shall  include  the next  subordinate  Class  provided  that  Certificateholders
evidencing  100% of the  Percentage  Interests  of such  Class  consent  to such
forgiveness.

     (c)  Following a default by a Borrower in the payment of a Balloon  Payment
on the related Maturity Date, or if the Special Servicer  reasonably  determines
that a default  with  respect to such  Balloon  Loan is  imminent,  the  Special
Servicer may elect to grant a one-year extension of such Balloon Loan;  provided
that the Special  Servicer may only extend such Balloon Loan if (i)  immediately
prior to the default on the Balloon Payment the related Borrower had made twelve
consecutive  Monthly  Payments on or prior to their Due Dates,  (ii) the Special
Servicer  determines in its reasonable judgment that such Borrower has attempted
in good faith to refinance  such Balloon Loan or Mortgaged  Property,  (iii) the
Special  Servicer  determines  that  (A)  extension  of  such  Balloon  Loan  is
consistent  with the Servicing  Standard and (B) extension of such Mortgage Loan
is likely to result in a recovery  which on a net  present  value basis would be
greater  than the  recovery  that would  result  from a  foreclosure,  (iv) such
extension  requires  that all cash flow on all  related  Mortgaged  Property  or
Properties in excess of amounts  required to operate and maintain such Mortgaged
Property or  Properties be applied to payments of principal and interest on such
Balloon Loan and (v) the Special Servicer  terminates the related Manager unless
the Special  Servicer  determines  that  retaining  such Manager is conducive to
maintaining the value of the related Mortgaged  Properties;  provided,  further,
the Special Servicer shall provide notice to the Trustee (and the Trustee hereby
agrees   to   forward   such   notice   immediately   upon   receipt   to   each
Certificateholder)  that the Special  Servicer has elected to extend the Balloon
Loan and  submit a case to the  Servicer  (an  "Extension  Case") and if (A) the
Servicer, based on such Extension Case but without any independent investigation
thereof, concurs with such Extension Case but Holders of Certificates evidencing
at least  66-2/3% of the  Percentage  Interests  of each  Class of  Certificates
entitled to vote direct the Special  Servicer not to extend or (B) the Servicer,
based on such Extension Case and without any independent  investigation thereof,
does not concur with such Extension Case and Holders of Certificates  evidencing
greater than (x) 50% of the aggregate  Voting  Rights of all  Certificateholders
entitled  to  vote  and  (y)  66-2/3%  of the  aggregate  Voting  Rights  of all
Certificateholders  entitled to vote who respond to such notice  within 30 days,
direct the Special  Servicer not to extend,  then the Special Servicer shall not
extend.

     The Special  Servicer may,  consistent with the Servicing  Standard,  grant
subsequent  one-year extensions of such Balloon Loan if (i) the related Borrower
has made twelve  consecutive  Monthly  Payments in an amount equal to or greater
than the Minimum Defaulted Monthly Payments,  (ii) the requirements set forth in
clauses (ii) - (iv) of the preceding paragraph are satisfied; provided, however,
the Special Servicer shall provide notice to the Trustee (and the Trustee hereby
agrees   to   forward   such   notice   immediately   upon   receipt   to   each
Certificateholder)  that the Special  Servicer has elected to extend the Balloon
Loan and submit an Extension Case to the Servicer and if (A) the Servicer, based
on such  Extension  Case but  without  any  independent  investigation  thereof,
concurs with such Extension Case but Holders of Certificates evidencing at least
66-2/3% of the Percentage  Interests of each Class of  Certificates  entitled to
vote direct the Special  Servicer  not to extend or (B) the  Servicer,  based on
such Extension Case and without any independent  investigation thereof, does not
concur with such Extension Case and Holders of Certificates  evidencing  greater
than (x) 50% of the aggregate Voting Rights of all  Certificateholders  entitled
to vote and (y) 66-2/3% of the aggregate Voting Rights of all Certificateholders
entitled to vote who respond to such notice within 30 Business Days,  direct the
Special Servicer not to extend,  then the Special Servicer shall not extend. The
holders of the Class A-CS1 and Class PS-1  Certificates  will not be entitled to
vote with respect to proposed  extensions of a Specially Serviced Mortgage Loan.
If the related Borrower fails to make a timely Minimum Defaulted Monthly Payment
more than once during any two year period after an extension of a Balloon  Loan,
no further extensions will be granted.

     During the 30-day period after notice of a proposed  extension of a Balloon
Loan  has  been  given,  each of the  Servicer  and  Special  Servicer  shall be
permitted to communicate  with the  Certificateholders  regarding its respective
position with respect to such  extension.  Notwithstanding  the  foregoing,  the
Special  Servicer shall not agree to any extension of a Mortgage Loan beyond the
earlier of two years prior to the Rated Final Distribution Date or past the date
which  is ten  years  prior  to the  expiration  of any  related  ground  lease.
Notwithstanding  the  foregoing,  the  Special  Servicer  may extend a defaulted
payment  due on the  Maturity  Date  of a  Balloon  Loan  and  grant  subsequent
extensions  pursuant to the Instructions of the Directing  Holders (as described
in paragraphs  (d) and (e) below).  The Servicer shall within five Business Days
after receipt of an Extension Case from the Special  Servicer,  give the Special
Servicer  written  notice as to whether or not it concurs with the extension set
forth in such Extension  Case. The Special  Servicer shall provide the necessary
information and back-up material for the Servicer to determine  whether it would
extend  prior to sending any such notice to the  Trustee.  The Special  Servicer
will notify the Servicer of any Mortgage Loan with respect to which the Borrower
has indicated in writing an intent to request an extension.

     The  Holders of the Class  A-CS1 and Class PS-1  Certificates  shall not be
entitled to vote with respect to proposed extensions of a Balloon Loan.

     Any  extension  of a Balloon  Loan  pursuant to this  Section  will require
monthly  payments in an amount  equal to or greater  than the Minimum  Defaulted
Monthly Payment.

     (d)   The   Special   Servicer   may  be   given   revocable   instructions
("Instructions")  (with a copy to the  Servicer) to extend a Specially  Serviced
Mortgage Loan that has defaulted on a Balloon Payment (which  extension shall be
conditioned on the  requirements  of clauses  (ii)-(iv) of Section 3.30(c) above
except that such Instructions shall not be subject to the rejection of the other
Certificateholders  and the related  Borrower  will not be required to have made
twelve consecutive  Monthly Payments on or prior to the Due Date) by the Holders
of Certificates  representing  greater than 50% of the Voting Rights of the most
subordinate  Class or Classes of Certificates  then  outstanding  representing a
minimum of 1.0% of the aggregate initial Certificate  Balances of all Classes of
Certificates  (or if the  Certificate  Balance of such Class or Classes has been
reduced to less than 40% of its initial Certificate Balance, the holders of such
Class  together  with the  Holders  of the next  most  subordinate  Class)  (the
"Directing  Holders")  under  the  following  circumstance  and  subject  to the
requirements of paragraph (e):

       (i)    If the Special Servicer has determined to commence  foreclosure or
              acquisition  proceedings,  the Special  Servicer  shall notify the
              Trustee  (and  the  Trustee  hereby  agrees  to  notify  Directing
              Holders), the Depositor and the Servicer of its proposed action;

       (ii)   If the Special Servicer  receives  contrary  Instructions from the
              Directing  Holders within seven days after notice was given to the
              Directing Holders (and the Trustee hereby agrees to forward to the
              Special  Servicer  promptly  any  Instructions   provided  by  the
              Directing   Holders),   the  Special   Servicer  will  delay  such
              proceedings, and the procedures described below shall apply to the
              servicing of such Mortgage Loan; and

       (iii)  In the event  that the  Special  Servicer  does not  receive  such
              Instructions  within such seven-day  period,  the Special Servicer
              may proceed in connection with the foreclosure or acquisition in a
              manner consistent with the Servicing Standard.

If the Directing Holders revoke their  Instructions to extend the Mortgage Loan,
the Special  Servicer  shall  service the Mortgage  Loan without  regard to such
original  Instructions;  provided,  however, that the Directing Holders shall be
required to maintain the Collateral Account in accordance with this Section 3.30
unless and until the Mortgage  Loan is no longer a Specially  Serviced  Mortgage
Loan for nine consecutive months or has been liquidated; and provided,  further,
that any such foreclosure shall be subject to the provisions of Section 3.10.

     (e) If the Special Servicer receives  Instructions and the Servicer has not
otherwise  been required to obtain an Updated  Appraisal as described in Section
3.10 above within the preceding twelve month period,  the Special Servicer shall
notify the  Servicer and the Servicer  shall as soon as  reasonably  practicable
obtain an Updated  Appraisal of the Mortgaged  Property (the cost of which shall
be paid by the Servicer as a Property  Advance),  in order to determine the fair
market value of such  Mortgaged  Property,  after  accounting  for the estimated
liquidation  and  carrying  costs (the  "Fair  Market  Value" of such  Mortgaged
Property).  Within two  Business  Days after the Special  Servicer's  receipt of
Instructions, the Servicer shall establish a segregated account (the "Collateral
Account") and the Directing  Holders  shall deposit  therein (at the  Servicer's
request),  in proportion to their  respective  Percentage  Interests,  an amount
equal  to the  lesser  of (i)  125% of the  Fair  Market  Value  of the  related
Mortgaged  Property and (ii) the outstanding  principal  balance of the Mortgage
Loan plus unreimbursed  Advances (with interest thereon at the Advance Rate) and
unpaid accrued  interest (the "Deposit").  If no Updated  Appraisal has yet been
obtained,  the amount of the Deposit will be determined  based on the Servicer's
estimate of the Fair Market Value of the Mortgaged Property, in which case, upon
the Servicer's receipt of such Updated  Appraisal,  the Servicer shall remit any
excess deposit to the Directing  Holders,  or the Directing Holders will deposit
in the Collateral  Account any shortfall,  as the case may be. In the event that
the Directing  Holders do not make the required deposit within two Business Days
following the Special Servicer's  receipt of Instructions,  the Special Servicer
shall act in  accordance  with the  Servicing  Standard  without  regard to such
Instructions.  The  Directing  Holders  shall be deemed to have  granted  to the
Servicer  for  the  benefit  of  Certificateholders  a first  priority  security
interest in the  Collateral  Account,  as security  for the  obligations  of the
Directing Holders.

     If the Special  Servicer is acting  pursuant to  Instructions,  the Special
Servicer shall direct the Servicer to withdraw from the  Collateral  Account for
deposit into the  Collection  Account on or prior to the Business Day  preceding
each  Servicer  Remittance  Date an amount  equal to the sum of (i) the  Minimum
Defaulted  Monthly  Payment on the related  Balloon  Loan and (ii) any  Property
Protection  Expenses  or any  expenses  incurred  to protect  and  preserve  the
security for a Mortgage  Loan or taxes and  assessments  or  insurance  premiums
(without  regard  to a  non-recoverability  determination),  and  the  Directing
Holders  shall,  upon request  therefor by the Servicer,  deposit from their own
funds into the  Collateral  Account  the amount of such P&I  Advance or Property
Advance.  Such withdrawals  shall be reimbursed,  with interest,  at the Advance
Rate (but in no event  greater  than the Default  Rate on the  related  Mortgage
Loan),  and shall be  recoverable  only from funds  recovered  from the  related
Mortgage  Loan  (whether  pursuant to  liquidation  or the  Mortgage  Loan being
brought current) but only after such funds have been applied to the purposes set
forth in Section 3.06(i)-(x). If the Directing Holders fail to make such deposit
within one (1) Business Day after receipt of the Servicer's request, the Special
Servicer  shall no longer be  required  to follow  such  Instructions  and shall
specially  service such Mortgage Loan as though no Instructions  had been given;
provided,  however, that the Directing Holders shall be required to maintain the
Collateral  Account in  accordance  with the  requirements  of this Section 3.30
unless and until the related  Mortgage  Loan is no longer a  Specially  Serviced
Mortgage Loan for nine consecutive  months or has been liquidated.  The Servicer
shall  invest  amounts  on  deposit  in  the  Collateral  Account  in  Permitted
Investments upon direction by the Directing Holders.  Directing Holders shall be
entitled to reinvestment  income as received,  and will reimburse the Collateral
Account for any losses incurred.  Any Collateral Account  established  hereunder
will be an "outside reserve fund"  beneficially  owned by the related  Directing
Holders for federal income tax purposes, and any amounts paid or reimbursed from
the  Upper-Tier  REMIC or  Lower-Tier  REMIC to the  Collateral  Account will be
treated as paid to the Directing Holders as beneficial owners.

     (f) If a Balloon Loan or the related Mortgaged Property which is subject to
Instructions is liquidated or disposed of, all Net Liquidation Proceeds shall be
deposited in the  Collection  Account and the Servicer  shall  withdraw from the
Collateral  Account,  and  deposit  into the  Collection  Account as  additional
Liquidation  Proceeds for distribution to  Certificateholders  the lesser of (a)
the amount by which 125% of the Fair Market Value (determined at the time of the
Deposit)  (plus  accrued and unpaid  interest,  accumulated  carrying  costs and
conveyance expenses) exceeds the net sales proceeds, and (b) the amount by which
the outstanding principal balance of the related Mortgage Loan plus unreimbursed
Advances (with interest  thereon) and unpaid  accrued  interest  exceeds the net
sales  proceeds,  provided  that in no event shall such  additional  Liquidation
Proceeds  exceed the  unpaid  principal  balance,  accrued  and unpaid  interest
(including  Default  Interest),  unreimbursed  Advances  made  by the  Servicer,
Special Servicer, Trustee or Fiscal Agent and interest thereon, and any expenses
paid by the Trust Fund with respect to such Mortgage Loan.

     If the amount  realized upon  disposition of the Mortgage Loan or Mortgaged
Property  exceeds 125% of the Fair Market Value,  the Servicer shall deposit the
excess in the Collection Account to the extent not required by applicable law to
be paid to the  related  Borrower.  If the  Mortgage  Loan  has not  been  sold,
liquidated or disposed of on or before the third anniversary of the Instructions
(or such earlier date so that the Trust Fund owns the Mortgaged  Property for no
longer than the period  permitted by Section  3.17(a)),  the  Directing  Holders
shall immediately  purchase the Mortgage Loan for a purchase price equal to Fair
Market Value  (determined  at the time of the  Deposit)  plus accrued and unpaid
interest,  accumulated carrying costs and conveyance expenses and, in connection
therewith,  amounts then on deposit in the  Collateral  Account shall be applied
first in payment of such purchase price. For purposes of this paragraph,  if the
Updated  Appraisal  is dated more than twelve  months prior to the date on which
such purchase is to occur,  then the Servicer shall obtain an Updated  Appraisal
upon which the  calculation  of Fair  Market  Value  shall be based and the term
"Fair Market Value" for purposes of the purchase  price and the first  paragraph
of this section (f) shall be the greater of (i) the Fair Market Value calculated
at the time the  Instructions  were first given and (ii) the Fair  Market  Value
calculated in connection with the referenced Updated Appraisal, provided that in
no event shall such price exceed the unpaid principal balance,  accrued interest
(including  Default  Interest),  unreimbursed  Advances  made  by the  Servicer,
Special  Servicer,  Trustee or Fiscal Agent,  and interest  thereon and expenses
paid by the Trust Fund with respect to such Mortgage Loan.

     If at any time  following  the  establishment  of a Collateral  Account and
prior to the  disposition of the Specially  Serviced  Mortgage Loan or Mortgaged
Property,  the  Mortgaged  Property  suffers a hazard  loss that  results in the
Mortgaged  Property not being rebuilt and payments to the Trustee are made under
the related  hazard  insurance  policy,  the  Servicer  shall pay all amounts on
deposit in the Collateral Account to the Directing Holders.  In addition,  after
amounts  required to be deposited in the  Collection  Account as set forth above
have  been  withdrawn  from  the  Collateral   Account  following   foreclosure,
liquidation,  disposition,  purchase  by  Directing  Holders,  or if the related
Mortgage  Loan  is no  longer  a  Specially  Serviced  Mortgage  Loan  for  nine
consecutive  months,  any remaining  amounts in the Collateral  Account shall be
released to the Directing Holders.

     (g)  Until the  disposition  of the  Specially  Serviced  Mortgage  Loan or
Mortgaged  Property as to which Directing Holders have provided  Instructions or
the cure of such  default,  no P&I Advances  shall be made in respect of amounts
otherwise distributable to the Class of the Directing Holders in respect of such
Mortgage  Loan.  The Trustee shall notify the Servicer at least one Business Day
prior to the Servicer  Remittance Date of the amount of scheduled  distributions
otherwise due to the Class of Certificates  held by the Directing Holders on the
related Distribution Date.

     (h) The Special  Servicer  shall  provide  copies of any  modifications  or
extensions to each Rating Agency.  All  modifications,  waivers,  amendments and
other actions entered into or taken in respect of the Mortgage Loans pursuant to
this Section  3.30 shall be in writing.  The Special  Servicer  shall notify the
Servicer and the Trustee, in writing, of any modification,  waiver, amendment or
other action  entered into or taken in respect of any Mortgage  Loan pursuant to
this Section 3.30,  prior to the effective date thereof and the date as of which
the related  modification,  waiver or  amendment  is to take  effect,  and shall
deliver to the  Trustee or the  related  Custodian  for  deposit in the  related
Mortgage  File (with a copy to the  Servicer)  an  original  counterpart  of the
agreement  relating to such  modification,  waiver,  amendment or other  action,
promptly  (and in any event within 10 Business  Days)  following  the  execution
thereof. Following the execution of any modification, waiver or amendment agreed
to by the Special Servicer pursuant to clauses (a) and (b)(i) above, the Special
Servicer shall deliver to the Trustee (with a copy to the Servicer) an Officer's
Certificate  setting forth in reasonable  detail the basis of the  determination
made by it pursuant to clause (a) and (b)(i) above.

     (i) If a modification,  waiver or amendment  results,  in and of itself, in
the withdrawal,  downgrade or qualification  of any of the then-current  ratings
assigned to any Class of Certificates  (not including the Class of Certificates,
if any, that  consented to such  actions),  then the Special  Servicer  shall be
terminated and shall be replaced pursuant to Section 7.02.

     (j) Any payment of interest  which is deferred as  described  herein  shall
not,  for  purposes,  including,  without  limitation,  of  calculating  monthly
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan,  notwithstanding that the terms of such Mortgage Loan
so permit or that such interest may actually be capitalized.

     (k) The Servicer or the Special Servicer, as applicable, shall be permitted
to modify,  waive or amend any term of a Mortgage Loan that is not in default or
as  to  which  default  is  not  reasonably   foreseeable,   but  only  if  such
modification, waiver or amendment (a) would not be "significant" as such term is
defined in Code Section 1001, or Treasury Regulations Section 1.860G-2(b)(3), as
determined  by the  Servicer or Special  Servicer  (and the  Servicer or Special
Servicer  may rely on an Opinion of Counsel in making such  determination),  (b)
would be in accordance  with the Servicing  Standard and (c) would not adversely
affect  in any  material  respect  the  interest  of any  Certificateholder  not
consenting thereto.  The consent thereto of the majority of Percentage Interests
of each Class of Certificates affected thereby or written confirmation from each
Rating Agency that such  modification,  waiver or amendment will not result in a
qualification, withdrawal or downgrading of the then current ratings assigned to
the Certificates shall not be required,  but either shall be conclusive evidence
that such  modification,  waiver or amendment would not adversely  affect in any
material respect the interest of any  Certificateholder  not consenting thereto.
Prior  to  waiving  any  "due on  sale"  clause,  taking  or  entering  into any
assumption agreement or permitting the release of a Borrower and substitution of
a new Borrower with respect to any Mortgage  Loan,  the Servicer  shall,  unless
otherwise  agreed by the Servicer  and Special  Servicer,  first  provide to the
Special Servicer a copy of its  recommendation and the materials upon which such
recommendation  is based and then  provide the Special  Servicer an  opportunity
during a four Business Day period prior to taking any such action to confer with
them as to  advisability  of such action (it being  understood that the Servicer
shall not have any obligation to follow any  instructions or directions given to
them by the Special Servicer with respect to such actions).

                       DISTRIBUTIONS TO CERTIFICATEHOLDERS

     SECTION 4.01. Distributions.

     (a) On each  Distribution  Date,  the Trustee  shall pay to itself from the
Distribution  Account the Trustee  Fee,  and the  remaining  amounts held in the
Distribution  Account shall be withdrawn (to the extent of Available  Funds) and
distributed in respect of the Lower-Tier Regular Interests as follows:

       (i)    The amounts and timing of  principal  and  interest  payments  and
              Prepayment Interest Shortfall allocations on each Lower-Tier REMIC
              Regular  Interest  will be identical to such amounts and timing on
              the   corresponding   Class  of  Related   Certificates  for  such
              Distribution  Date,  except  that,  solely for this  purpose,  (A)
              principal will be distributed on the Class A-1A1-L Interest in the
              amount and at the time the  corresponding  amount of  principal is
              distributed  on  the  Class  A-1A  Certificates  pursuant  to  the
              definition  of  Class  A-1A  Component  1  Balance,  and  (B)  all
              calculations  with  respect  to  the  Related  Lower-Tier  Regular
              Interests shall be made as though (x) the Class A-1A,  Class A-1B,
              Class A-1C, Class A-2, Class A-3, Class A-4, Class A-5, Class B-1,
              Class  B-2,  Class  B-3,  Class  B-4,  Class  B-5,  and  Class B-6
              Pass-Through Rates were equal to the Weighted Average Net Mortgage
              Pass-Through  Rate,  (y) the Class PS-1 and Class  A-CS1  Notional
              Balances were zero at all times,  and (z) any  Reduction  Interest
              Shortfall   allocated   to,   or  any   restoration   of   amounts
              corresponding to such Reduction Interest Shortfall distributed on,
              the Class PS-1  Certificates  on such  Distribution  Date based on
              notional  reductions  to  the  Certificate  Balance  of a  Related
              Certificate  were allocated to or distributed  on, as the case may
              be, the  Lower-Tier  Regular  Interest  that  corresponds  to such
              Related Certificate.

       (ii)   Prepayment  Premiums  shall  be  distributed  in  respect  of  the
              Lower-Tier   Regular   Interests   in   accordance   with  Section
              4.01(c)(ii).

       (iii)  Realized  Losses  shall be  allocated  to,  and shall  reduce  the
              Certificate   Balances  of,  each  Class  of  Lower-Tier   Regular
              Interests  without  distribution on any Distribution  Date, to the
              extent  that the  Certificate  Balance of such Class  exceeds  the
              Certificate  Balance  of the  corresponding  Related  Certificates
              because of Realized Losses allocated to such Related Certificates;
              provided  that  Realized  Losses   allocable  to  the  Class  A-1A
              Certificates shall be allocated pro rata between the Class A-1A1-L
              and Class A-1A2-L Interests based on their  Certificate  Balances.
              Amounts recovered in respect of any amounts previously written off
              as Realized  Losses will be distributed to the Related  Lower-Tier
              Regular Interests, to the extent that amounts recovered in respect
              of any  amounts  previously  written  off as  Realized  Losses are
              distributed to the corresponding Related Certificates,  and to the
              Class  A-1A1-L  and  Class  A-1A2-L  Interests  pro rata  based on
              Realized   Losses   previously   allocated  in  reduction  of  the
              Certificate Balances of such Lower-Tier Regular Interests.

       (iv)   Any  amounts  remaining  in the  Distribution  Account  after  the
              distribution  set  forth  above in this  Section  4.01(a)(i)-(iii)
              shall be distributed to the Class LR Certificates.

     (b) On  each  Distribution  Date,  amounts  distributed  on the  Lower-Tier
Regular  Interests  pursuant  to  Section  4.01(a)  shall  be  deposited  in the
Upper-Tier  Distribution  Account,  and  Holders of each  Class of  Certificates
(other than the Class LR Certificates) shall receive  distributions from amounts
on deposit in the  Upper-Tier  Distribution  Account in respect of interest  and
principal,  subject  to  Section  4.01(h),  in the  amounts  and in the order of
priority set forth below:

                    interest,  up to an  amount  equal to the  aggregate  unpaid
                    Class  Interest  Shortfalls  previously  allocated  to  such
                    Classes;

                    Amount  less  amounts  of  Principal   Distribution   Amount
                    distributed  pursuant  to  all  prior  clauses,   until  the

                    Certificates,   in  reduction  of  the  Certificate  Balance
                    thereof,  an  amount  equal  to the  Principal  Distribution

                    respect  of  interest,  up to an amount  equal to the unpaid
                    Class  Interest  Shortfalls  previously  allocated  to  such
                    Class, (B) to the Class PS-1  Certificates in respect of the
                    Reduction Interest  Distribution  Amount attributable to the
                    notional  reduction in the Certificate  Balance of the Class
                    A-2 Certificates pursuant to Section 4.01(i) up to an amount
                    equal  to the  Reduction  Interest  Distribution  Amount  so
                    attributable and (C) to the Class PS-1  Certificates,  up to
                    an amount equal to the unpaid Reduction Interest  Shortfalls
                    previously  allocated  to the  Class  PS-1  Certificates  in

                    Distribution  Amount  distributed   pursuant  to  all  prior
                    clauses,  until the  Certificate  Balance  of such  Class is
                    reduced to zero;

          (xlv)     Forty-fifth,  to the Class B-6  Certificates,  to the extent
                    not  distributed  pursuant  to all  prior  clauses,  for the
                    unreimbursed  amounts of Realized Losses,  if any, an amount
                    equal to the aggregate of such unreimbursed  Realized Losses
                    previously allocated to such Class;

          (xlvi)    Forty-sixth, pro rata, (A) to the Class PS-1 Certificates in
                    respect  of  the  Reduction  Interest   Distribution  Amount
                    attributable  to the notional  reduction in the  Certificate
                    Balance of the Class B-7 and Class B-7H  Certificates  up to
                    an  amount  equal  to the  Reduction  Interest  Distribution
                    Amount  so   attributable   and  (B)  to  the   Class   PS-1
                    Certificates,  up to an amount equal to the unpaid Reduction
                    Interest Shortfalls  previously  allocated to the Class PS-1
                    Certificates in respect of Reduction  Interest  Distribution
                    Amounts distributable under Clause (A);

          (xlvii)   Forty-seventh,  pro rata,  to the  Class B-7 and Class  B-7H
                    Certificates  in respect of interest,  up to an amount equal
                    to the aggregate Class Interest Distribution Amounts of such
                    classes;

          (xlviii)  Forty-eighth,  pro rata,  to the  Class  B-7 and Class  B-7H
                    Certificates  in respect of interest,  up to an amount equal
                    to the aggregate unpaid Class Interest Shortfalls previously
                    allocated to such classes;

          (xlix)    Forty-ninth,  pro rata, based on Certificate  Balance to the
                    Class B-7 and Class B-7H  Certificates  in  reduction of the
                    Certificate   Balances  thereof,  an  amount  equal  to  the
                    Principal  Distribution Amount less amounts of the Principal
                    Distribution  Amount  distributed   pursuant  to  all  prior
                    clauses, until the Certificate Balance of each such class is
                    reduced to zero;

          (l)       Fiftieth,  pro  rata,  to  the  Class  B-7  and  Class  B-7H
                    Certificates,  to the extent not distributed pursuant to all
                    prior  clauses,  for the  unreimbursed  amounts of  Realized
                    Losses,  if any, an amount  equal to the  aggregate  of such
                    unreimbursed  Realized Losses  previously  allocated to such
                    classes; and

          (li)      Fifty-first, to the Class R Certificates.

     On each  Distribution  Date,  amounts  received  on a  Mortgage  Loan  that
represent  recoveries of Subordinate Class Advance Amounts shall be allocated by
the  Trustee to the Class of  Certificates  and the Related  Lower-Tier  Regular
Interest that advanced the related  Subordinate  Class Advance Amount in respect
of the distributions to which such Class of Certificates and Related  Lower-Tier
Regular  Interest  were  entitled  on  the  Distribution   Date  on  which  such
distributions  were reduced by such  Subordinate  Class Advance Amount.  Amounts
allocated  with respect to interest shall be applied to any related unpaid Class
Interest  Shortfalls.   On  each  Distribution  Date,  the  Paying  Agent  shall
distribute such recoveries of Subordinate Class Advance Amounts allocated to the
related Class of Certificates and Related  Lower-Tier  Regular Interest pursuant
to this paragraph to such Class and Related Lower-Tier Regular Interest.

     All  references  to pro  rata in the  preceding  clauses  with  respect  to
interest and Class Interest  Shortfalls  shall mean pro rata based on the amount
distributable  pursuant  to  such  clauses,  with  respect  to  distribution  of
principal other than for unreimbursed  Realized Losses shall mean pro rata based
on  Certificate  Balance  and with  respect  to  distributions  with  respect to
unreimbursed  Realized  Losses  shall  mean pro  rata  based  on the  amount  of
unreimbursed Realized Losses previously allocated to the applicable Classes.

     (c) (i) On each  Distribution  Date,  following the  distribution  from the
Distribution  Account in respect of the Lower-Tier Regular Interests pursuant to
Section 4.01(c)(ii), the Paying Agent shall make distributions of any Prepayment
Premiums  with  respect to any  Principal  Prepayments  received  in the related
Collection Period from amounts deposited in the Upper-Tier  Distribution Account
pursuant to Section 3.05(c) in the following amounts (as additional payments and
not as payments of interest and principal due thereunder) and order of priority,
with  respect  to the  Certificates  of each  Class in each  case to the  extent
remaining amounts of Prepayment Premiums are available therefor:

       (I)    First, to the Class A-CS1 Certificates, an amount equal to (A) the
              present value  (discounted at the Discount Rate (as defined below)
              for the Class A-CS1  Certificates plus the Spread Rate (as defined
              below) for the Class A-CS1 Certificates) of the aggregate interest
              that  would  have  been  paid  in  respect  of  the  Class   A-CS1
              Certificates from the Distribution Date occurring in the following
              month until the Notional  Balance of the Class A-CS1  Certificates
              would have been  reduced to zero had the  related  prepayment  not
              occurred,  minus (B) the present value (discounted at the Discount
              Rate for the Class A-CS1 Certificates plus the Spread Rate for the
              Class A-CS1  Certificates) of the aggregate  interest that will be
              paid in respect of Class A-CS1  Certificates from the Distribution
              Date occurring in the following  month until the Notional  Balance
              of the Class A-CS1  Certificates is reduced to zero following such
              prepayment  (assuming no further  prepayments are made except that
              all Mortgage  Loans prepay on  Anticipated  Repayment  Dates where
              applicable);

       (II)   Second, to the Class PS-1 Certificates, an amount equal to (A) the
              present value  (discounted at the Discount Rate for the Class PS-1
              Certificates plus the Spread Rate for the Class PS-1 Certificates)
              of the aggregate  interest that would have been paid in respect of
              the Class PS-1  Certificates  from the Distribution Date occurring
              in the  following  month until the  Notional  Balance of the Class
              PS-1 Certificates  would have been reduced to zero had the related
              prepayment not occurred,  minus (B) the present value  (discounted
              at the  Discount  Rate for the Class  PS-1  Certificates  plus the
              Spread  Rate for the Class  PS-1  Certificates)  of the  aggregate
              interest  that will be paid in respect of Class PS-1  Certificates
              from the Distribution  Date occurring in the following month until
              the Notional Balance of the Class PS-1  Certificates is reduced to
              zero following such  prepayment  (assuming no further  prepayments
              are made  except that all  Mortgage  Loans  prepay on  Anticipated
              Repayment Dates where applicable);

       (III)  Third, to the Class A-1A Certificates,  an amount equal to (A) the
              present value  (discounted at the Discount Rate for the Class A-1A
              Certificates plus the Spread Rate for the Class A-1A Certificates)
              of the aggregate  principal and interest that would have been paid
              in respect of the Class A-1A  Certificates  from the  Distribution
              Date  occurring  in the  following  month  until  the  Certificate
              Balance of the Class A-1A Certificates  would have been reduced to
              zero had the related prepayment not occurred, minus the sum of (B)
              the amount of such prepayment  distributed in respect of the Class
              A-1A  Certificates  and (C) the present value  (discounted  at the
              Discount Rate for the Class A-1A Certificates plus the Spread Rate
              for the Class A-1A  Certificates)  of the aggregate  principal and
              interest   that  will  be  paid  in  respect  of  the  Class  A-1A
              Certificates from the Distribution Date occurring in the following
              month until the Certificate Balance of the Class A-1A Certificates
              is reduced to zero following such prepayment  (assuming no further
              prepayments  are made except  that all  Mortgage  Loans  prepay on
              Anticipated Repayment Dates where applicable);

       (IV)   Fourth, to the Class A-1B Certificates, an amount equal to (A) the
              present value  (discounted at the Discount Rate for the Class A-1B
              Certificates plus the Spread Rate for the Class A-1B Certificates)
              of the aggregate  principal and interest that would have been paid
              in respect of the Class A-1B  Certificates  from the  Distribution
              Date  occurring  in the  following  month  until  the  Certificate
              Balance of the Class A-1B Certificates  would have been reduced to
              zero had the related prepayment not occurred, minus the sum of (B)
              the amount of such prepayment  distributed in respect of the Class
              A-1B  Certificates  and (C) the present value  (discounted  at the
              Discount Rate for the Class A-1B Certificates plus the Spread Rate
              for the Class A-1B  Certificates)  of the aggregate  principal and
              interest   that  will  be  paid  in  respect  of  the  Class  A-1B
              Certificates from the Distribution Date occurring in the following
              month until the Certificate Balance of the Class A-1B Certificates
              is reduced to zero following such prepayment  (assuming no further
              prepayments  are made except  that all  Mortgage  Loans  prepay on
              Anticipated Repayment Dates where applicable); and

       (V)    Fifth, to the Class A-1C Certificates,  an amount equal to (A) the
              present value  (discounted at the Discount Rate for the Class A-1C
              Certificates plus the Spread Rate for the Class A-1C Certificates)
              of the aggregate  principal and interest that would have been paid
              in respect of the Class A-1C  Certificates  from the  Distribution
              Date  occurring  in the  following  month  until  the  Certificate
              Balance of the Class A-1C Certificates  would have been reduced to
              zero had the related prepayment not occurred, minus the sum of (B)
              the amount of such prepayment  distributed in respect of the Class
              A-1C  Certificates  and (C) the present value  (discounted  at the
              Discount Rate for the Class A-1C Certificates plus the Spread Rate
              for the Class A-1C  Certificates)  of the aggregate  principal and
              interest   that  will  be  paid  in  respect  of  the  Class  A-1C
              Certificates from the Distribution Date occurring in the following
              month until the Certificate Balance of the Class A-1C Certificates
              is reduced to zero following such prepayment  (assuming no further
              prepayments  are made except  that all  Mortgage  Loans  prepay on
              Anticipated Repayment Dates where applicable).

In all  clauses  above,  Prepayment  Premiums  will  only  be  distributed  on a
Distribution Date (i) if the respective  Certificate Balance or Notional Balance
of the related Class or Classes is greater than zero on the last Business Day of
the Interest Accrual Period ending  immediately  prior to such Distribution Date
and (ii) if the amount computed  pursuant to the related clause above is greater
than  zero.  Any  Prepayment  Premiums  remaining  following  the  distributions
described in the preceding clauses (I) through (VI) and any Post-lockout  Return
of Fee Amounts shall be  distributed  to holders of the Class B-7H  Certificates
regardless of whether the Certificate Balance thereof has been reduced to zero.

Notwithstanding  the foregoing,  Prepayment Premiums shall be distributed on any
Distribution  Date  only to the  extent  they are  received  in  respect  of the
Mortgage Loans in the related Collection Period.

         (ii) On each  Distribution  Date,  prior  to the  distributions  to the
Certificates  from the  Upper-Tier  Distribution  Account  pursuant  to  Section
4.01(c)(i),  the Lower-Tier  Regular  Interests shall receive  distributions  in
respect of Prepayment Premiums in proportion to their Certificate Balances.

     (d) Intentionally deleted.

     (e) The Certificate  Balances of each Class of Regular  Certificates (other
than the Class  A-CS1 and  Class  PS-1  Certificates)  will be  reduced  without
distribution  on any  Distribution  Date as a  write-off  to the  extent  of any
Realized  Losses  allocated  to such Class with  respect to such date.  Any such
write-offs  will be applied to Classes of Regular  Certificates in the following
order,  in each case until the  Certificate  Balance of such Class is reduced to
zero:  first, to the Class B-7  Certificates  and Class B-7H  Certificates,  pro
rata, based on their respective  Certificate  Balances;  second to the Class B-6
Certificates;  third, to the Class B-5  Certificates;  fourth,  to the Class B-4
Certificates,  fifth,  to the Class B-3  Certificates;  sixth,  to the Class B-2
Certificates;  seventh, to the Class B-1 Certificates;  eighth, to the Class A-5
Certificates;  ninth,  to the Class A-4  Certificates;  tenth,  to the Class A-3
Certificates; eleventh, to the Class A-2 Certificates; and finally, to the Class
A-1A,  Class  A-1B  and  Class  A-1C  Certificates,  pro  rata,  based  on their
respective Certificate Balances and pro rata as between the Class A-1A Component
1 Balance and the Class A-1A  Component  2 Balance.  Any  amounts  recovered  in
respect  of  amounts   previously  written  off  as  Realized  Losses  shall  be
distributed to the Classes of  Certificates  described above in reverse order of
allocation of Realized  Losses  thereto.  Shortfalls  in Available  Funds due to
servicing or trustee  compensation  other than the Servicing Fee and the Trustee
Fee (including servicing compensation resulting solely from interest on Advances
(to the extent not payable from Default  Interest)),  extraordinary  expenses of
the Trust  Fund  (other  than  indemnification  expenses),  a  reduction  in the
Mortgage  Rate on a Mortgage  Loan by a bankruptcy  court  pursuant to a plan of
reorganization or pursuant to any of its equitable  powers, or otherwise,  shall
be allocated in the same manner as Realized Losses to the Certificates.

     Realized Losses and such other amounts described above which are applied to
each Class of Certificates will be allocated to reduce the Certificate  Balances
of the Related  Lower-Tier  Regular  Interests and pro rata as between the Class
A-1A1-L and Class A-1A2-L Interests based on their Certificate Balances.

     (f) All amounts  distributable to a Class of Certificates  pursuant to this
Section 4.01 on each  Distribution  Date shall be  allocated  pro rata among the
outstanding Certificates in each such Class based on their respective Percentage
Interests. Such distributions shall be made on each Distribution Date other than
the Termination Date to each  Certificateholder  of record on the related Record
Date by check  mailed by first Class mail to the  address set forth  therefor in
the  Certificate  Register or, provided that such Holder shall have provided the
Paying Agent with wire instructions in writing at least five Business Days prior
to the related Record Date, by wire transfer of immediately  available  funds to
the  account  of such  Holder at a bank or other  entity  located  in the United
States and having  appropriate  facilities  therefor.  The final distribution on
each  Certificate  shall be made in like manner,  but only upon  presentment and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Holders of such final distribution.

     (g)  Except as  otherwise  provided  in  Section  9.01 with  respect  to an
Anticipated Termination Date, the Trustee shall, no later than the fifteenth day
of the month in the month  preceding  the month in which the final  distribution
with respect to any Class of  Certificates  is expected to be made, mail to each
Holder of such Class of Certificates, on such date a notice to the effect that:

          (A)  the Trustee reasonably expects based upon information  previously
               provided to it that the final  distribution  with respect to such
               Class of Certificates will be made on such Distribution Date, but
               only upon  presentation and surrender of such Certificates at the
               office of the Trustee therein specified, and

          (B)  if such final  distribution is made on such Distribution Date, no
               interest  shall accrue on such  Certificates  from and after such
               Distribution Date;

provided,  however,  that  the  Class  V-1,  Class  V-2,  Class R and  Class  LR
Certificates  shall  remain  outstanding  until  there  is  no  other  Class  of
Certificates  or Lower-Tier  Regular  Interests  outstanding  and the Class B-7H
Certificates shall be deemed to be outstanding so long as there are any Mortgage
Loans outstanding that provide for payments of Prepayment Premiums in connection
with voluntary or involuntary prepayments.

     Any funds not  distributed  to any  Holder or  Holders  of such  Classes of
Certificates on such  Distribution Date because of the failure of such Holder or
Holders to tender their Certificates  shall, on such date, be set aside and held
in trust for the benefit of the appropriate  non-tendering Holder or Holders. If
any  Certificates  as to which  notice has been given  pursuant to this  Section
4.01(g) shall not have been surrendered for cancellation within six months after
the time specified in such notice, the Trustee shall mail a second notice to the
remaining non-tendering Holders to surrender their Certificates for cancellation
to receive the final distribution with respect thereto. If within one year after
the second notice not all of such  Certificates  shall have been surrendered for
cancellation,  the Trustee may,  directly or through an agent,  take appropriate
steps to contact the remaining  non-tendering  Holders  concerning  surrender of
their Certificates. The costs and expenses of holding such funds in trust and of
contacting  such  Holders  shall be paid out of such funds.  If within two years
after the second notice any such  Certificates  shall not have been  surrendered
for  cancellation,  the  Paying  Agent  shall  pay to the  Trustee  all  amounts
distributable to the Holders thereof, and the Trustee shall thereafter hold such
amounts for the benefit of such Holders until the earlier of (i) its termination
as Trustee hereunder and the transfer of such amounts to a successor Trustee and
(ii) the  termination of the Trust Fund and  distribution of such amounts to the
Class R Certificateholders. No interest shall accrue or be payable to any Holder
on any  amount  held in trust  hereunder  or by the  Trustee as a result of such
Holder's  failure to surrender its  Certificate(s)  for final payment thereof in
accordance  with this  Section  4.01(g).  Any such  amounts  transferred  to the
Trustee  may be  invested  in  Permitted  Investments  and all  income  and gain
realized from investment of such funds shall be for the benefit of the Trustee.

     (h)  Notwithstanding  any provision in this Agreement to the contrary,  the
aggregate amount distributable to each Class pursuant to this Section 4.01 shall
be reduced by the aggregate  amount paid to any Person  pursuant to Section 6.03
or Section  8.05(b) and (d), such  reduction to be allocated  among such Classes
pro rata, based upon the respective amounts so distributable without taking into
account  the  provision  of this  Section  4.01(h).  Such  reduction  of amounts
otherwise  distributable  to a Class  shall be  allocated  first in  respect  of
interest and second in respect of principal.  For purposes of determining  Class
Interest Shortfalls and Certificate  Balances,  the amount of any such reduction
so allocated to a Class shall be deemed to have been distributed to such Class.

     (i) The Certificate  Balances of the Class A-2, Class A-3, Class A-4, Class
A-5,  Class B-1, Class B-2, Class B-3, Class B-4, Class B-5, Class B-6 and Class
B-7 Certificates  shall be notionally  reduced on any  Distribution  Date to the
extent of any Delinquency  Reduction Amounts or Appraisal Reduction Amounts with
respect to such  Distribution  Date;  provided that (i) if a Delinquency  and an
Appraisal  Reduction Event occur with respect to the same  Distribution Date and
the same  Mortgage  Loan,  the  reduction  shall equal the  Appraisal  Reduction
Amount,  (ii)  following  the  occurrence of an Appraisal  Reduction  Event with
respect to any Mortgage Loan, no further Delinquency  Reduction Amounts shall be
applied with respect to such Mortgage Loan and any Delinquency Reduction Amounts
previously  applied shall be reversed and (iii) for any  Distribution  Date, the
aggregate of the Appraisal  Reduction Amounts and Delinquency  Reduction Amounts
shall  not  exceed  the  Certificate   Balance  (as  adjusted  by  any  notional
reductions) of the most subordinate Class of Certificates  outstanding among the
Class B-7,  Class B-6,  Class B-5,  Class B-4,  Class B-3, Class B-2, Class B-1,
Class A-5,  Class A-4, Class A-3 and Class A-2  Certificates  (and to the extent
the  aggregate of the  Appraisal  Reduction  Amounts and  Delinquency  Reduction
Amounts exceeds such Certificate Balance, such excess shall be applied,  subject
to any reversal  described below, to notionally reduce the next most subordinate
Class of Certificates on the next Distribution  Date). Any such reductions shall
be applied  notionally,  first,  to the Class B-7 and Class  B-7H  Certificates,
second to the  Class B-6  Certificates,  third,  to the Class B-5  Certificates,
fourth,  to the Class B-4  Certificates,  fifth, to the Class B-3  Certificates,
sixth, to the Class B-2  Certificates,  seventh,  to the Class B-1 Certificates,
eighth,  to the Class  A-5  Certificates,  ninth to the Class A-4  Certificates,
tenth to the Class A-3 Certificates,  and finally, to the Class A-2 Certificates
(provided in each case that no Certificate  Balance in respect of any such class
shall  be  notionally  reduced  below  zero).  Any  notional  reduction  of  the
Certificate  Balance  of such  Certificates  as a result of any  Delinquency  or
Appraisal Reduction Event shall be reversed to the extent there is a recovery of
any or all of the  Delinquency  Amounts  or a  Realized  Loss.  Additionally,  a
reversal or additional  reduction  shall occur to the extent that the Servicer's
Appraisal  Estimate  is less than or greater  than the  Appraisal  Reduction  as
adjusted  to take into  account a  subsequent  independent  MAI  Appraisal.  For
purposes of calculating Interest Accrual Amounts, any such reduction or reversal
made on the  Distribution  Date occurring in an Interest Accrual Period shall be
deemed to have been made on the first day of such Interest Accrual Period.

     (j)  Shortfalls  in Available  Funds  resulting  from  Prepayment  Interest
Shortfalls  in  excess  of  Servicer  Prepayment  Interest  Shortfalls  shall be
allocated to and be deemed distributed to, each Class of Certificates, pro rata,
based upon the Class Interest  Distribution Amount (plus the aggregate Reduction
Interest  Distribution  Amount,  in the  case of the  Class  PS-1  Certificates)
distributable  to each such  Class,  and  shall be  allocated  to each  Class of
Lower-Tier  Regular  Interests in the same manner in which interest is allocated
pursuant to Section 4.01(a)(i). Servicer Prepayment Interest Shortfalls shall be
deposited  by the  Servicer  into  the  Collection  Account  on or  prior to the
Servicer Remittance Date.

     Shortfalls  in Available  Funds  resulting  from  indemnification  expenses
pursuant to Section 6.03 shall be allocated to each Class of  Certificates,  pro
rata,  based on  amounts  distributable  to each  Class and shall be  allocated,
first,   in  respect  of  interest  and,   second,   in  respect  of  principal.
Indemnification  expenses which are applied to each Class of Certificates  shall

for all  Certificates  of each  applicable  Class  and per  $1,000  of  original

Loan Status Report,  the Historical  Loss Estimate  Report,  the Historical Loan
Modification  Report,  the REO Status Report and a Watch List (indicating  those
Mortgage  Loans that the  Servicer  has  determined  are in jeopardy of becoming
Specially  Serviced  Mortgage  Loans)  provided  by the  Servicer to the Trustee
pursuant to Section  3.13(c) and 3.13(e) on the Servicer  Remittance  Date.  The
information  that  pertains  to  Specially   Serviced  Mortgage  Loans  and  REO
Properties  reflected  in such  reports  shall be based  solely upon the reports
delivered  by the Special  Servicer to the  Servicer at least one  Business  Day
prior to the related Servicer  Remittance Date.  Absent manifest error, (i) none
of the Servicer,  the Special  Servicer or the Trustee shall be responsible  for
the accuracy or completeness of any information  supplied to it by a Borrower or
third  party  that  is  included  in  any  reports,  statements,   materials  or
information  prepared or provided by the Servicer,  the Special  Servicer or the
Trustee,  as  applicable,  (ii) the  Trustee  shall not be  responsible  for the
accuracy or completeness  of any  information  supplied to it by the Servicer or
Special  Servicer  that is included in any  reports,  statements,  materials  or
information  prepared  or  provided  by the  Servicer  or Special  Servicer,  as
applicable,  and (iii) the Trustee shall be entitled to  conclusively  rely upon
the Servicer's  reports and the Special  Servicer's  reports without any duty or
obligation  to  recompute,  verify or  re-evaluate  any of the  amounts or other
information stated therein.

     Commencing in May,  1998, the  information  contained in the reports in the
preceding  paragraph  of this  Section  4.02(c)  shall be made  available to the
Trustee electronically by the Servicer in the form of the standard CSSA Reports,
and the  Trustee  will in lieu of  mailing  such  reports as  described  in such
preceding  paragraph make such reports available  electronically in such form to
Certificateholders  using the media  mutually  agreed upon by the  Trustee,  the
Underwriter and the Depositor; provided, however, that the Trustee will continue
to provide  Certificateholders  with a written copy of such reports upon request
in the manner described in such preceding paragraph.

     The  Trustee  shall  deliver a copy of each  Operating  Statement  Analysis
report and NOI  Adjustment  Worksheet  that it receives  from the  Servicer  and
Special  Servicer to the  Depositor,  each  Underwriter  and each Rating  Agency
promptly after its receipt  thereof.  Upon request,  the Trustee shall make such
reports  available  to the  Certificateholders  and the Special  Servicer.  Upon
request,  the Trustee shall also make available any NOI Adjustment Worksheet for
a Mortgaged  Property or REO  Property in the  possession  of the Trustee to any
potential investor (as identified by the  Certificateholder  or Beneficial Owner
that is selling its Certificates or beneficial interest) in the Certificates.

     (d) The Trustee shall make available at its offices, during normal business
hours,  upon not less than two Business  Day's prior  notice,  for review by any
Certificateholder, any prospective investor in a Certificate, the Depositor, the
Servicer,  the  Sub-Servicer,  the  Special  Servicer,  any Rating  Agency,  any
Underwriter, and any other Person to whom the Depositor believes such disclosure
is appropriate,  originals or copies of documents relating to the Mortgage Loans
and any  related  REO  Properties  to the extent in its  possession,  including,
without  limitation,  the following  items  (except to the extent  prohibited by
applicable  law or to the extent it is aware that such  disclosure is prohibited
by the Mortgage  Documents provided that the Trustee shall have no obligation to
review the Mortgage Documents for such prohibition):  (i) this Agreement and any
amendments  thereto;  (ii) all  Distribution  Date  Statements  delivered to the
Certificateholders   since  the  Closing  Date;   (iii)  all  annual   Officers'
Certificates and all accountants'  reports  delivered by the Servicer or Special
Servicer to the Trustee  since the Closing Date  regarding  compliance  with the
relevant agreements; (iv) the most recent property inspection report prepared by
or on  behalf  of the  Servicer  or the  Special  Servicer  in  respect  of each
Mortgaged Property;  (v) the most recent annual (or more frequent, if available)
operating  statements,  rent rolls (to the extent such rent rolls have been made
available  by the related  Borrower)  and/or  lease  summaries  and retail sales
information,  if any,  collected  by or on behalf of the Servicer or the Special
Servicer in respect to each Mortgaged Property;  (vi) any and all modifications,
waivers  and  amendments  of the terms of a Mortgage  Loan  entered  into by the
Servicer and/or the Special Servicer;  (vii) any and all Officers'  Certificates
and other evidence delivered to or by the Trustee to support the Servicer's, the
Trustee's  or the Fiscal  Agent's,  as the case may be,  determination  that any
Advance,  if made,  would be a  Nonrecoverable  Advance;  and  (viii)  any other
materials  not  otherwise  required  to  be  provided  hereunder  provided  to a
requesting  Certificateholder  as provided in this Agreement in situations where
such  requesting  Certificateholder  declined  to enter  into a  confidentiality
agreement with the Servicer.  Copies of any and all of the foregoing  items will
be  available  from the Trustee upon  request.  The Trustee will be permitted to
require  payment by the  requesting  party (other than a Rating Agency) of a sum
sufficient to cover the reasonable costs and expenses of making such information
available and providing any copies thereof.  The Trustee's obligation under this
Section  4.02(d) to make  available  any  document  is subject to the  Trustee's
receipt of such document.

     The Trustee shall provide  access to the  information  in the  Distribution
Date  Statements  referred  to in Section  4.02(a)  telephonically  through  the
Trustee's ASAP System,  electronically through the Trustee's website or bulletin
board  service or by such other  mechanism as the Trustee may have in place from
time to time.

     (e) On or within two Business Days  following each  Distribution  Date, the
Trustee  shall  prepare and furnish to the  Financial  Market  Publisher and the
Underwriter, using the format and media mutually agreed upon by the Trustee, the
Financial  Market  Publisher,  the Underwriter and the Depositor,  the following
information  regarding each Mortgage Loan and any other  information  reasonably
requested by the Underwriter and available to the Trustee:

       (i)    the Loan Number;

       (ii)   each related Mortgage Rate; and

       (iii)  the principal balance as of such Distribution Date.

The  Trustee  shall only be  obligated  to deliver the  statements,  reports and
information  contemplated  by this  Section  4.02 to the extent it receives  the
necessary  underlying  information from the Servicer or the Special Servicer and
shall not be liable for any failure to deliver any thereof on the prescribed due
dates,  to the  extent  caused by  failure to  receive  timely  such  underlying
information.  Nothing  herein shall  obligate  the Trustee,  the Servicer or the
Special  Servicer  to violate  any  applicable  law  prohibiting  disclosure  of
information  with respect to any  Borrower  and the failure of the Trustee,  the
Servicer or the  Special  Servicer to  disseminate  information  for such reason
shall not be a breach hereof.

     SECTION 4.03. Compliance with Withholding Requirements.

     Notwithstanding  any other  provision of this  Agreement,  the Paying Agent
shall comply with all federal withholding  requirements with respect to payments
to  Certificateholders  of interest or original  issue  discount that the Paying
Agent  reasonably  believes  are  applicable  under the  Code.  The  consent  of
Certificateholders  shall not be required for any such  withholding.  The Paying
Agent agrees that it will not  withhold  with respect to payments of interest or
original issue discount in the case of a Holder that is non-U.S. Person that has
furnished or caused to be furnished (i) an effective  Form W-8 or Form W-9 or an
acceptable  substitute  form or a  successor  form and who is not a  "10-percent
shareholder"  within the meaning of Code Section  871(h)(3)(B)  or a "controlled
foreign corporation"  described in Code Section 881(c)(3)(C) with respect to the
Trust Fund or the  Depositor,  or (ii) an effective  Form 4224 or an  acceptable
substitute  form or a successor form. In the event the Paying Agent or its agent
withholds  any amount  from  interest  or original  issue  discount  payments or
advances  thereof  to any  Certificateholder  pursuant  to  federal  withholding
requirements,  the Paying  Agent  shall  indicate  the amount  withheld  to such
Certificateholder.  Any  amount so  withheld  shall be  treated  as having  been
distributed to such Certificateholder for all purposes of this Agreement.

     SECTION 4.04. REMIC Compliance.

     (a) The parties intend that each of the Upper-Tier REMIC and the Lower-Tier
REMIC shall constitute, and that the affairs of each of the Upper-Tier REMIC and
the  Lower-Tier  REMIC shall be conducted so as to qualify it as, a "real estate
mortgage  investment  conduit" as defined in, and in accordance  with, the REMIC
Provisions,  and the provisions  hereof shall be interpreted  consistently  with
this  intention.  In furtherance of such  intention,  the Trustee shall,  to the
extent permitted by applicable law, act as agent, and is hereby appointed to act
as agent, of each of the Upper-Tier  REMIC and the Lower-Tier REMIC and shall on
behalf of each of the Upper-Tier  REMIC and the Lower-Tier  REMIC:  (i) prepare,
sign and file,  or cause to be prepared and filed,  all required Tax Returns for
each of the Upper-Tier REMIC and the Lower-Tier REMIC,  using a calendar year as
the taxable year for each of the Upper-Tier  REMIC and the Lower-Tier REMIC when
and as required by the REMIC Provisions and other applicable  federal,  state or
local  income  tax  laws;  (ii)  make  an  election,  on  behalf  of each of the
Upper-Tier REMIC and the Lower-Tier REMIC, to be treated as a REMIC on Form 1066
for its first  taxable  year, in  accordance  with the REMIC  Provisions;  (iii)
prepare  and  forward,   or  cause  to  be  prepared  and   forwarded,   to  the
Certificateholders  and the Internal  Revenue  Service and applicable  state and
local  tax  authorities  all  information  reports  as and when  required  to be
provided to them in accordance with the REMIC Provisions of the Code and Section
4.07; (iv) if the filing or  distribution of any documents of an  administrative
nature not  addressed in clauses (i) through  (iii) of this  Section  4.04(a) is
then  required by the REMIC  Provisions  in order to maintain  the status of the
Upper-Tier REMIC or the Lower-Tier REMIC as a REMIC or is otherwise  required by
the Code,  prepare,  sign and file or  distribute,  or cause to be prepared  and
signed and filed or distributed, such documents with or to such Persons when and
as required by the REMIC  Provisions  or the Code or  comparable  provisions  of
state and local law;  (v) within  thirty  days of the Closing  Date,  furnish or
cause to be  furnished  to the  Internal  Revenue  Service,  on Form  8811 or as
otherwise may be required by the Code, the name, title and address of the Person
that the Holders of the  Certificates  may contact for tax information  relating
thereto  (and  the  Trustee  shall  act as the  representative  of  each  of the
Upper-Tier REMIC and the Lower-Tier REMIC for this purpose),  together with such
additional  information  as may be required by such Form,  and shall update such
information at the time or times and in the manner required by the Code (and the
Depositor  agrees  within 10 Business  Days of the  Closing  Date to provide any
information  reasonably  requested by the Servicer,  the Special Servicer or the
Trustee and  necessary  to make such  filing);  and (vi)  maintain  such records
relating  to each of the  Upper-Tier  REMIC and the  Lower-Tier  REMIC as may be
necessary  to  prepare  the   foregoing   returns,   schedules,   statements  or
information,  such records, for federal income tax purposes, to be maintained on
a calendar year and on an accrual  basis.  The Holder of the largest  Percentage
Interest in the Class R or Class LR Certificates shall be the tax matters person
of the  Upper-Tier  REMIC or the  Lower-Tier  REMIC,  respectively,  pursuant to
Treasury Regulations Section 1.860F-4(d). If more than one Holder should hold an
equal  Percentage  Interest in the Class R or Class LR Certificates  larger than
that held by any other Holder, the first such Holder to have acquired such Class
R or Class LR Certificates  shall be such tax matters person.  The Trustee shall
act as  attorney-in-fact  and  agent for the tax  matters  person of each of the
Upper-Tier REMIC and Lower-Tier REMIC, and each Holder of a Percentage  Interest
in the Class R or Class LR Certificates, by acceptance hereof, is deemed to have
consented to the  Trustee's  appointment  in such capacity and agrees to execute
any  documents  required  to give  effect  thereto,  and any fees  and  expenses
incurred  by the  Trustee  in  connection  with any audit or  administrative  or
judicial  proceeding  shall be paid by the Trust  Fund.  The  Trustee  shall not
intentionally  take any action or  intentionally  omit to take any action if, in
taking or omitting to take such  action,  the Trustee  knows that such action or
omission (as the case may be) would cause the termination of the REMIC status of
the  Upper-Tier  REMIC or the  Lower-Tier  REMIC or the imposition of tax on the
Upper-Tier  REMIC or the Lower-Tier  REMIC (other than a tax on income expressly
permitted  or  contemplated  to be  received  by the  terms of this  Agreement).
Notwithstanding  any provision of this  paragraph to the  contrary,  the Trustee
shall not be required to take any action that the Trustee in good faith believes
to be inconsistent  with any other  provision of this  Agreement,  nor shall the
Trustee  be  deemed  in  violation  of this  paragraph  if it takes  any  action
expressly  required or authorized by any other provision of this Agreement,  and
the Trustee shall have no responsibility or liability with respect to any act or
omission of the Depositor,  the Servicer or the Special  Servicer which does not
enable the Trustee to comply  with any of clauses (i) through  (vi) of the fifth
preceding sentence or which results in any action contemplated by clauses (i) or
(ii) of the next  succeeding  sentence.  In this  regard the  Trustee  shall (i)
exercise  reasonable  care  not to  allow  the  occurrence  of  any  "prohibited
transactions"  within the  meaning  of Code  Section  860F(a),  unless the party
seeking  such action  shall have  delivered to the Trustee an Opinion of Counsel
(at such party's expense) that such occurrence would not (A) result in a taxable
gain,  (B) otherwise  subject the  Upper-Tier  REMIC or Lower-Tier  REMIC to tax
(other than a tax at the highest marginal  corporate tax rate on net income from
foreclosure  property),  or (C) cause either the Upper-Tier  REMIC or Lower-Tier
REMIC to fail to qualify as a REMIC;  and (ii) exercise  reasonable  care not to
allow the Trust Fund to receive income from the  performance of services or from
assets not permitted under the REMIC Provisions to be held by a REMIC (provided,
however,  that the receipt of any income expressly  permitted or contemplated by
the terms of this Agreement shall not be deemed to violate this clause). None of
the Servicer,  the Special  Servicer and the Depositor  shall be  responsible or
liable  (except in  connection  with any act or omission  referred to in the two
preceding  sentences)  for  any  failure  by the  Trustee  to  comply  with  the
provisions of this Section  4.04.  The  Depositor,  the Servicer and the Special
Servicer  shall  cooperate in a timely  manner with the Trustee in supplying any
information  within the  Depositor's,  the Servicer's or the Special  Servicer's
control (other than any confidential  information) that is reasonably  necessary
to enable the Trustee to perform its duties under this Section 4.04.

     (b) The following  assumptions  are to be used for purposes of  determining
the anticipated  payments of principal and interest for calculating the original
yield to  maturity  and  original  issue  discount  with  respect to the Regular
Certificates:  (i)  each  Mortgage  Loan  will pay  principal  and  interest  in
accordance  with its terms and  scheduled  payments  will be timely  received on
their Due Dates, provided that the Mortgage Loans will prepay in accordance with
the  Prepayment  Assumption;  (ii) none of the  Servicer,  the Depositor and the
Class LR Certificateholders will exercise the right described in Section 9.01 of
this  Agreement  to cause  early  termination  of the Trust  Fund;  and (iii) no
Mortgage Loan is  repurchased  by the Mortgage Loan Seller,  the Depositor or an
Mortgage Loan Seller pursuant to Article II hereof.

     SECTION 4.05. Imposition of Tax on the Trust Fund.

     In the event that any tax,  including  interest,  penalties or assessments,
additional  amounts or additions to tax, is imposed on the  Upper-Tier  REMIC or
Lower-Tier   REMIC,   such  tax  shall  be  charged  against  amounts  otherwise
distributable  to the  Holders  of the  Certificates;  provided,  that any taxes
imposed on any net income from  foreclosure  property  pursuant to Code  Section
860G(d)  or any  similar  tax  imposed  by a state or local  jurisdiction  shall
instead be treated as an expense of the related REO Property in determining  Net
REO Proceeds  with  respect to the REO Property  (and until such taxes are paid,
the Special  Servicer from time to time shall  withdraw from the REO Account and
transfer  to the  Trustee  amounts  reasonably  determined  by the Trustee to be
necessary  to pay such taxes,  which the Trustee  shall  maintain in a separate,
non-interest-bearing  account,  and the Trustee shall deposit in the  Collection
Account the excess  determined by the Trustee from time to time of the amount in
such  account  over the amount  necessary  to pay such  taxes) and shall be paid
therefrom;  provided  that any such tax imposed on net income  from  foreclosure
property  that  exceeds the amount in any such  reserve  shall be retained  from
Available Funds as provided in Section 3.06(viii) and the next sentence.  Except
as provided in the preceding  sentence,  the Trustee is hereby authorized to and
shall retain or cause to be retained from Available  Funds  sufficient  funds to
pay or provide for the payment of, and to actually  pay,  such tax as is legally
owed by the Upper-Tier REMIC or Lower-Tier REMIC (but such  authorization  shall
not prevent the Trustee from  contesting,  at the expense of the Trust Fund, any
such tax in appropriate  proceedings,  and  withholding  payment of such tax, if
permitted  by law,  pending  the  outcome of such  proceedings).  The Trustee is
hereby  authorized  to and shall  segregate  or cause to be  segregated,  into a
separate  non-interest  bearing account, (i) the net income from any "prohibited
transaction"  under Code Section 860F(a) or (ii) the amount of any  contribution
to the  Upper-Tier  REMIC or  Lower-Tier  REMIC  after the  Startup  Day that is
subject to tax under Code Section 860G(d) and use such income or amount,  to the
extent  necessary,  to pay such tax (and return the balance thereof,  if any, to
the Collection Account or the Upper-Tier  Distribution  Account, as the case may
be). To the extent that any such tax is paid to the  Internal  Revenue  Service,
the  Trustee  shall  retain  an  equal  amount  from  future  amounts  otherwise
distributable  to the Holders of the Class R or the Class LR Certificates as the
case may be,  and shall  distribute  such  retained  amounts  to the  Holders of
Regular Certificates or Lower-Tier Regular Interests, as applicable,  until they
are fully  reimbursed and then to the Holders of the Class R Certificates or the
Class LR Certificates, as applicable. Neither the Servicer, the Special Servicer
nor the Trustee shall be  responsible  for any taxes  imposed on the  Upper-Tier
REMIC or  Lower-Tier  REMIC except to the extent such tax is  attributable  to a
breach of a representation or warranty of the Servicer,  the Special Servicer or
the Trustee or an act or omission of the Servicer,  the Special  Servicer or the
Trustee in  contravention  of this Agreement in both cases,  provided,  further,
that such breach,  act or omission could result in liability under Section 6.03,
in the case of the Servicer or Section 4.04 or 8.01, in the case of the Trustee.
Notwithstanding  anything in this Agreement to the contrary,  in each such case,
the Servicer or the Special  Servicer  shall not be  responsible  for  Trustee's
breaches,  acts or omissions,  and the Trustee shall not be responsible  for the
breaches, acts or omissions of the Servicer or the Special Servicer.

     SECTION 4.06. Remittances; P&I Advances.

     (a)  "Applicable  Monthly  Payment"  shall mean, for any Mortgage Loan with
respect to any month,  (A) if such Mortgage Loan is delinquent as to its Balloon
Payment  (including  any such  Mortgage  Loan as to which the related  Mortgaged
Property has become an REO Property), the related Assumed Scheduled Payment, (B)
if such  Mortgage  Loan has been  extended  in  accordance  with the  terms  and
conditions otherwise set forth in this Agreement,  the Minimum Defaulted Monthly
Payment and (C) if such  Mortgage  Loan is not  described by the  preceding  two
sentences  (including  any such Mortgage Loan as to which the related  Mortgaged
Property has become an REO Property),  the Monthly  Payment (after giving effect
to any  modification  other than as  described  in (A) or (B) above);  provided,
however, that for purposes of calculating the amount of any P&I Advance required
to be made by the Servicer, the Trustee or the Fiscal Agent, notwithstanding the
amount of such Applicable  Monthly Payment,  interest shall be calculated at the
Mortgage Pass-Through Rate. The Applicable Monthly Payment shall be reduced, for
purposes of P&I  Advances,  by any  modifications  pursuant  to Section  3.30 or
otherwise  and by any  reductions  by a bankruptcy  court  pursuant to a plan of
reorganization or pursuant to any of its equitable powers.

     (b) On the Servicer Remittance Date immediately preceding each Distribution
Date, the Servicer shall:

       (i)    remit to the Trustee for  deposit in the  Distribution  Account an
              amount equal to the Prepayment  Premiums  received by the Servicer
              or  Special  Servicer  in the  Collection  Period  preceding  such
              Distribution Date;

       (ii)   remit to the Trustee for  deposit in the  Distribution  Account an
              amount equal to the aggregate of the  Available  Funds (other than
              P&I  Advances),  the Trustee  Fee and  Subordinate  Class  Advance
              Recoveries for such Distribution Date; and

       (iii)  make a P&I Advance by depositing into the Distribution Account, in
              an amount equal to the sum of the Applicable  Monthly Payments for
              each Mortgage Loan to the extent such amounts were not received on
              such Mortgage Loan as of the close of business on the  immediately
              preceding   Determination  Date,  unless  related  recoveries  are
              received by the close of business on the day prior to the Servicer
              Remittance  Date (and therefore are not included in the remittance
              described in the preceding clause (ii)).

     (c) Intentionally deleted.

     (d) Notwithstanding Section 4.06(b)(iii),  the Servicer shall (i) make only
one full advance in respect of each  Mortgage  Loan  pursuant to such Section in
respect of the most subordinate  Class of Certificates  then outstanding  unless
the related  Delinquency  is cured prior to the  following Due Date and (ii) not
make any P&I Advance in respect of Reduction Interest  Distribution  Amounts and
Reduction  Interest  Shortfalls,  and  accordingly,  the Servicer may reduce the
aggregate  amount of P&I Advances to be deposited by the Servicer on the related
Servicer Remittance Date in respect of such amounts the Servicer is not required
to advance.  For purposes of clause (i) of the preceding sentence,  the Servicer
shall  reduce the  aggregate  amount of the P&I  Advance it would  otherwise  be
required to make with respect to any Mortgage  Loans that have had more than one
uncured  Delinquency  by the  lesser  of (a) the  total  amount  that  would  be
distributable  to the  most  subordinate  outstanding  Class in  respect  of all
Mortgage Loans on such Distribution Date if the Servicer were to make a full P&I
Advance and (b) the amount of the  delinquent  Monthly  Payment on such Mortgage
Loans.  In the event that there is more than one Mortgage Loan that has had more
than one uncured  Delinquency as of any Servicer  Remittance Date and the amount
determined  pursuant  to clause (b) of the  preceding  sentence  exceeds the P&I
amount  determined  pursuant to clause (a)  thereof,  the P&I  Advance  that the
Servicer  makes in respect of such  Mortgage  Loans  (i.e.,  the amount by which
clause (b)  exceeds  clause  (a)) will be deemed to have been made in respect of
such delinquent Monthly Payment,  pro rata in accordance with the amounts of any
such delinquent Monthly Payments. (The first P&I Advance made by the Servicer in
respect  of a  Mortgage  Loan  shall  be  deemed  to be in  respect  of the most
subordinate  Class for  purposes  of clause  (i) of the first  sentence  of this
paragraph.) In addition,  on any Servicer  Remittance Date on which the Servicer
is not  required to make a P&I  Advance for the benefit of the most  subordinate
Class as described  above,  the Servicer  shall  initially make such P&I Advance
(for accounting purposes only) and shall,  immediately  subsequent to the making
of the P&I Advance on such Servicer  Remittance Date,  reimburse itself for such
P&I Advance from amounts otherwise  distributable to such most subordinate Class
on the related Distribution Date (such amount of reimbursement or any amount not
advanced by the Servicer which, if advanced, could have been so reimbursed,  the
"Subordinate  Class Advance Amount").  The Trustee shall provide to the Servicer
written  statements  one  Business  Day prior to the  Servicer  Remittance  Date
listing (i) the aggregate Reduction Interest  Distribution Amounts and Reduction
Interest  Shortfalls for such Distribution Date and (ii) the distribution due to
the Holders of the most subordinate Class of Certificates.

     (e) The Servicer  shall not be required or permitted to make an advance for
Excess Interest or Default  Interest.  The amount required to be advanced by the
Servicer in respect of Applicable  Monthly  Payments on Mortgage Loans that have
been subject to an Appraisal  Reduction  Event will equal the product of (i) the
amount  required to be advanced by the Servicer  without  giving  effect to such
Appraisal  Reduction Amounts and (ii) a fraction,  the numerator of which is the
Stated Principal Balance of the Mortgage Loan (as of the last day of the related
Collection  Period)  less  any  Appraisal  Reduction  Amounts  thereof  and  the
denominator of which is the Stated Principal  Balance (as of the last day of the
related Collection Period). The amount to be advanced by the Servicer in respect
of any Mortgage Loan on any Distribution Date shall be reduced by the greater of
the  reduction in respect of any  Appraisal  Reduction  Event and the  reduction
described in clause (d)(i) above.

     (f) Any amount  advanced by the Servicer  pursuant to Section  4.06(b)(iii)
shall  constitute  a P&I Advance  for all  purposes  of this  Agreement  and the
Servicer shall be entitled to reimbursement  (with interest at the Advance Rate)
thereof to the full extent as otherwise set forth in this Agreement.

     (g) If as of 11:00 a.m., New York City time, on any  Distribution  Date the
Servicer  shall not have made the P&I Advance  required to have been made on the
related Servicer Remittance Date pursuant to Section  4.06(b)(iii),  the Trustee
shall  immediately  notify the Fiscal Agent by telephone  promptly  confirmed in
writing,  and the Trustee shall no later than 12:00 noon, New York City time, on
such Business Day deposit into the Distribution Account in immediately available
funds an amount equal to the P&I Advances  otherwise  required to have been made
by the  Servicer.  If the Trustee  fails to make any P&I Advance  required to be
made under this Section  4.06,  the Fiscal Agent shall make such P&I Advance not
later than 2:00 p.m., New York City time, on such Business Day and, thereby, the
Trustee shall not be in default under this Agreement.

     (h)  None of the  Servicer,  the  Trustee  or the  Fiscal  Agent  shall  be
obligated to make a P&I Advance as to any Monthly  Payment or Assumed  Scheduled
Payment or Minimum  Defaulted Monthly Payment on any date on which a P&I Advance
is  otherwise  required to be made by this  Section  4.06 if the  Servicer,  the
Trustee or Fiscal Agent,  as applicable,  determines that such advance will be a
Nonrecoverable  Advance. The Servicer shall be required to provide notice to the
Trustee and the Fiscal Agent on or prior to the Servicer  Remittance Date of any
such non-recoverability determination made on or prior to such date. The Trustee
and  the  Fiscal  Agent  shall  be  entitled  to  rely,  conclusively,   on  any
determination  by  the  Servicer  that  a  P&I  Advance,  if  made,  would  be a
Nonrecoverable  Advance;  provided,  however, that if the Servicer has failed to
make a P&I Advance for reasons other than a  determination  by the Servicer that
such Advance would be a Nonrecoverable  Advance, the Trustee or Fiscal Agent, as
applicable,  shall make such advance within the time periods required by Section
4.06(g)  unless  the  Trustee  or the  Fiscal  Agent,  in  good  faith,  makes a
determination  prior to the times specified in Section 4.06(g) that such advance
would  be a  Nonrecoverable  Advance.  The  Trustee  and the  Fiscal  Agent,  in
determining whether or not an Advance previously made is, or a proposed Advance,
if made,  would be, a  Nonrecoverable  Advance shall be subject to the standards
applicable to the Servicer hereunder.

     (i) The Servicer, the Trustee or the Fiscal Agent, as applicable,  shall be
entitled to the  reimbursement  of P&I Advances it makes to the extent permitted
pursuant to Section 3.06(ii) of this Agreement together with any related Advance
Interest Amount in respect of such P&I Advances to the extent permitted pursuant
to Section  3.06(iii) and the Servicer and Special  Servicer hereby covenant and
agree to promptly  seek and effect the  reimbursement  of such Advances from the
related  Borrowers  to the extent  permitted by  applicable  law and the related
Mortgage Loan.

     SECTION 4.07. Grantor Trust Reporting.

     The parties  intend that the portions of the Trust Fund  consisting  of (i)
the Default Interest and the Default Interest  Distribution Account and (ii) the
Excess Interest and the Excess Interest  Distribution  Account shall constitute,
and that the affairs of the Trust Fund  (exclusive of the Trust REMICs) shall be
conducted so as to qualify such portion as a "grantor trust" under the Code, and
the provisions hereof shall be interpreted  consistently with this intention. In
furtherance  of such  intention,  the  Trustee  shall  furnish  or  cause  to be
furnished to Class V-1 and Class V-2  Certificateholders and shall file or cause
to be filed with the Internal  Revenue  Service  together with Form 1041 or such
other form as may be applicable,  income with respect to their  applicable share
of Default  Interest  and the amount of any  interest on  unreimbursed  Advances
payable to the  Servicer,  the  Trustee  and the Fiscal  Agent,  as  applicable,
therefrom   pursuant  to  Section  3.06(iii)  in  the  case  of  the  Class  V-1
Certificates,  and Excess Interest in the case of the Class V-2 Certificates, at
the time or times and in the manner required by the Code.

Certificates  of each Class will be issuable in registered form only, in minimum
denominations  of  authorized   Certificate  Balance  or  Notional  Balance,  as
applicable,  as described in the succeeding table, and multiples of $1 in excess
thereof (or such  lesser  amount if the  Certificate  or  Notional  Balance,  as
applicable,  is not a multiple of $1).  With respect to any  Certificate  or any
beneficial  interest in a Certificate,  the "Denomination"  thereof shall be (i)
the  amount  (A) set forth on the face  thereof or (B) in the case of any Global
Certificate,  set forth on a schedule  attached  thereto  or, in the case of any
beneficial interest in a Global  Certificate,  the amount set forth on the books

     Each Certificate will share ratably in all rights of the related Class. The
Class B-7H  Certificates  shall be issuable in a single,  registered  definitive
physical  certificate  evidencing its aggregate initial Certificate Balance. The
Class V-1, Class V-2, Class R and LR  Certificates  will each be issuable in one
or more registered, definitive physical certificates in minimum denominations of
5% Percentage  Interests and integral  multiples of a 1% Percentage  Interest in
excess thereof and together  aggregating the entire 100% Percentage  Interest in
each such Class.

     The  Global  Certificates  shall  be  issued  as one or  more  certificates
registered in the name of a nominee designated by the Depository, and Beneficial
Owners shall hold  interests in the Global  Certificates  through the book-entry
facilities  of  the  Depository  in  the  minimum  Denominations  and  aggregate
Denominations and Classes as set forth above.

     The Global  Certificates  shall in all  respects  be  entitled  to the same
benefits  under this  Agreement as  Individual  Certificates  authenticated  and
delivered hereunder.

     (b) Except  insofar as pertains to any  Individual  Certificate,  the Trust
Fund,  the Paying  Agent and the Trustee  may for all  purposes  (including  the
making of payments  due on the Global  Certificates  and the giving of notice to
Holders  thereof) deal with the Depository as the authorized  representative  of
the Beneficial  Owners with respect to the Global  Certificates for the purposes
of exercising the rights of  Certificateholders  hereunder;  provided,  however,
that,  for  purposes  of  providing  information  pursuant  to  Section  3.22 or
transmitting  communications pursuant to Section 5.05(a), to the extent that the
Depositor  has  provided  the Trustee  with the names of  Beneficial  Owners the
Trustee shall provide such information to such Beneficial  Owners directly.  The
rights of Beneficial Owners with respect to Global Certificates shall be limited
to those established by law and agreements between such  Certificateholders  and
the  Depository  and  Depository  Participants.  Except as set forth in  Section
5.01(e) below, Beneficial Owners of Global Certificates shall not be entitled to
physical  certificates  for the  Global  Certificates  as to which  they are the
Beneficial Owners. Requests and directions from, and votes of, the Depository as
Holder of the Global  Certificates shall not be deemed  inconsistent if they are
made with respect to different Beneficial Owners. Subject to the restrictions on
transfer set forth in Section 5.02 and  Applicable  Procedures,  the holder of a
beneficial  interest  in a  Private  Global  Certificate  may  request  that the
Depositor,  or an agent  thereof,  cause the Depository (or any Agent Member) to
notify the Certificate  Registrar and the Certificate  Custodian in writing of a
request for transfer or exchange of such  beneficial  interest for an Individual
Certificate or  Certificates.  Upon receipt of such a request and payment by the
related  Beneficial Owner of any attendant  expenses,  the Depositor shall cause
the issuance  and  delivery of such  Individual  Certificates.  The  Certificate
Registrar   may  establish  a  reasonable   record  date  in   connection   with
solicitations of consents from or voting by  Certificateholders  and give notice
to the  Depository  of such record  date.  Without  the  written  consent of the
Depositor  and  the  Certificate   Registrar,   no  Global  Certificate  may  be
transferred by the Depository  except to a successor  Depository  that agrees to
hold the Global Certificates for the account of the Beneficial Owners.

     (c) Any of the  Certificates  may be issued  with  appropriate  insertions,
omissions,  substitutions  and  variations,  and may have imprinted or otherwise
reproduced thereon such legend or legends,  not inconsistent with the provisions
of this  Agreement,  as may be  required to comply with any law or with rules or
regulations  pursuant  thereto,  or with the rules of any  securities  market in
which the Certificates are admitted to trading, or to conform to general usage.

     (d) The  Global  Certificates  (i) shall be  delivered  by the  Certificate
Registrar to the Depository or,  pursuant to the  Depository's  instructions  on
behalf of the Depository to, and deposited with, the Certificate Custodian,  and
in either case shall be registered in the name of Cede & Co. and (ii) shall bear
a legend substantially to the following effect:

                  "Unless  this   certificate  is  presented  by  an  authorized
                  representative  of The Depository  Trust  Company,  a New York
                  corporation   ("DTC"),   to  the  Certificate   Registrar  for
                  registration  of  transfer,   exchange  or  payment,  and  any
                  certificate  issued is registered in the name of Cede & Co. or
                  in  such  other  name  as  is  requested   by  an   authorized
                  representative  of DTC (and any  payment is made to Cede & Co.
                  or to such  other  entity  as is  requested  by an  authorized
                  representative  of DTC),  ANY  TRANSFER,  PLEDGE  OR OTHER USE
                  HEREOF FOR VALUE OR  OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
                  inasmuch as the  registered  owner hereof,  Cede & Co., has an
                  interest herein."

     The Global  Certificates may be deposited with such other Depository as the
Certificate  Registrar  may from time to time  designate,  and  shall  bear such
legend as may be appropriate.

     (e) If  (i)  the  Depository  advises  the  Trustee  in  writing  that  the
Depository  is no longer  willing,  qualified or able  properly to discharge its
responsibilities as Depository,  and the Trustee is unable to locate a qualified
successor,  (ii) the  Depositor  or the Trustee,  at its sole option,  elects to
terminate the book-entry  system  through the Depository  with respect to all or
any portion of any Class of  Certificates  or (iii) after the  occurrence  of an
Event  of  Default,  Beneficial  Owners  owning  not  less  than a  majority  in
Certificate  Balance  or  Notional  Balance,   as  applicable,   of  the  Global
Certificate  for any  Class  then  outstanding  advise  the  Depository  through
Depository  Participants in writing that the continuation of a book-entry system
through the Depository is no longer in the best interest of the Beneficial Owner
or Owners of such Global  Certificate,  the Trustee  shall  notify the  affected
Beneficial  Owner or Owners  through the  Depository  of the  occurrence of such
event and the availability of Individual  Certificates to such Beneficial Owners
requesting  them.  Upon surrender to the Trustee of Global  Certificates  by the
Depository,  accompanied by  registration  instructions  from the Depository for
registration of transfer,  the Trustee shall issue the Individual  Certificates.
Neither the Trustee, the Fiscal Agent, the Certificate Registrar,  the Servicer,
the Special  Servicer nor the Depositor shall be liable for any actions taken by
the  Depository  or its nominee,  including,  without  limitation,  any delay in
delivery of such instructions. Upon the issuance of Individual Certificates, the
Trustee, the Fiscal Agent, the Certificate Registrar,  the Servicer, the Special
Servicer,   and  the  Depositor   shall  recognize  the  Holders  of  Individual
Certificates as Certificateholders hereunder.

     (f) If the  Trustee,  its agents or the  Servicer or Special  Servicer  has
instituted or has been directed to institute any judicial  proceeding in a court
to enforce the rights of the Certificateholders under the Certificates,  and the
Trustee,  the Servicer or the Special  Servicer has been advised by counsel that
in  connection  with such  proceeding  it is  necessary or  appropriate  for the
Trustee,  the  Servicer or the  Special  Servicer  to obtain  possession  of the
Certificates,  the Trustee, the Servicer or the Special Servicer may in its sole
discretion   determine   that  the   Certificates   represented  by  the  Global
Certificates shall no longer be represented by such Global Certificates. In such
event, the Trustee or the Authenticating Agent will execute and authenticate and
the   Certificate   Registrar   will  deliver,   in  exchange  for  such  Global
Certificates,  Individual  Certificates  (and if the Trustee or the  Certificate
Custodian has in its possession Individual Certificates previously executed, the
Authenticating  Agent  will  authenticate  and the  Certificate  Registrar  will
deliver such Certificates) in a Denomination equal to the aggregate Denomination
of such Global Certificates.

     (g) If the Trust  Fund  ceases to be  subject to Section 13 or 15(d) of the
Exchange  Act, the Trustee  shall make  available to each Holder of a Class B-7,
Class B-7H, Class V-1, Class V-2, Class R or Class LR Certificate,  upon request
of  such  a  Holder,  information  substantially  equivalent  in  scope  to  the
information  currently filed by the Servicer with the Commission pursuant to the
Exchange  Act,  plus such  additional  information  required to be provided  for
securities  qualifying  for resales  under Rule 144A under the Act, all of which
information referred to in this paragraph shall be provided on a timely basis to
the Trustee by the Servicer.

     For so long as the Class B-7, Class B-7H,  Class V-1, Class V-2, Class R or
Class LR Certificates remain outstanding,  neither the Depositor nor the Trustee
nor the Certificate  Registrar shall take any action which would cause the Trust
Fund to fail to be subject to Section 15(d) of the Exchange Act.

     (h) Each  Certificate may be printed or in typewritten or similar form, and
each Certificate  shall,  upon original issue, be executed and  authenticated by
the Trustee or the  Authenticating  Agent and  delivered to the  Depositor.  All
Certificates shall be executed by manual or facsimile signature on behalf of the
Trustee  or  Authenticating   Agent  by  an  authorized  officer  or  signatory.
Certificates  bearing the  signature  of an  individual  who was at any time the
proper  officer or signatory of the Trustee or  Authenticating  Agent shall bind
the Trustee or Authenticating  Agent,  notwithstanding  that such individual has
ceased  to  hold  such  office  or  position  prior  to  the  delivery  of  such
Certificates  or did not  hold  such  office  or  position  at the  date of such
Certificates.  No  Certificate  shall be  entitled  to any  benefit  under  this
Agreement, or be valid for any purpose, unless there appears on such Certificate
a certificate  of  authentication  in the form set forth in Exhibits A-1 through
A-24  executed  by the  Authenticating  Agent  by  manual  signature,  and  such
certificate of authentication upon any Certificate shall be conclusive evidence,
and the only evidence,  that such  Certificate has been duly  authenticated  and
delivered  hereunder.  All  Certificates  shall  be  dated  the  date  of  their
authentication.

     SECTION 5.02.  Registration, Transfer and Exchange of Certificates.

     (a) The  Trustee  shall  keep or  cause to be kept at the  Corporate  Trust
Office books (the  "Certificate  Register") for the  registration,  transfer and
exchange of Certificates (the Trustee, in such capacity,  being the "Certificate
Registrar"). The names and addresses of all Certificateholders and the names and
addresses of the  transferees  of any  Certificates  shall be  registered in the
Certificate  Register;  provided,  however,  in no event  shall the  Certificate
Registrar be required to maintain in the  Certificate  Register the names of the
individual  Participants  holding beneficial interests in the Trust Fund through
the Depository.  The Person in whose name any Certificate is so registered shall
be deemed and treated as the sole owner and Holder  thereof for all  purposes of
this Agreement and the Depositor,  the Certificate Registrar,  the Servicer, the
Special Servicer,  the Trustee, the Fiscal Agent, any Paying Agent and any agent
of any of them shall not be affected by any notice or knowledge to the contrary.
An  Individual  Certificate  is  transferable  or  exchangeable  only  upon  the
surrender of such  Certificate  to the  Certificate  Registrar at the  Corporate
Trust Office together with an assignment and transfer (executed by the Holder or
his duly authorized attorney),  subject to the requirements of Sections 5.02(c),
(d),  (e),  (f),  (g) and (h).  Upon  request of the  Trustee,  the  Certificate
Registrar  shall provide the Trustee with the names,  addresses  and  Percentage
Interests of the Holders.

     Neither the Trustee nor the Certificate Registrar shall have any obligation
or duty to monitor,  determine or inquire as to compliance  with any restriction
or transfer  imposed under Article 5 of this  Agreement or under  applicable law
with respect to any transfer of any Certificate,  or any interest therein, other
than to require  delivery  of the  certification(s)  and/or  opinions of counsel
described in Article 5 applicable  with  respect to changes in  registration  of
record  ownership of Certificates in the Certificate  Register.  The Trustee and
the  Certificate  Registrar  shall have no liability  for  transfers,  including
transfers made through the book-entry facilities of the Depository or between or
among  Depository  participants  or  Beneficial  Owners  made  in  violation  of
applicable restrictions.

     (b)  Upon  surrender  for   registration  of  transfer  of  any  Individual
Certificate,  subject to the  requirements of Sections  5.02(c),  (d), (e), (f),
(g), (h) and (i), the Trustee shall execute and the  Authenticating  Agent shall
duly authenticate in the name of the designated  transferee or transferees,  one
or more new Certificates in  Denominations  of a like aggregate  Denomination as
the  Individual  Certificate  being  surrendered.  Such  Certificates  shall  be
delivered by the Certificate  Registrar in accordance with Section 5.02(e). Each
Certificate  surrendered  for  registration  of transfer  shall be canceled  and
subsequently destroyed by the Certificate Registrar. Each new Certificate issued
pursuant to this Section 5.02 shall be  registered  in the name of any Person as
the  transferring  Holder may  request,  subject to the  provisions  of Sections
5.02(c), (d), (e), (f), (g), (h) and (i).

     (c) In addition to the  provisions of Sections  5.02(d),  (e), (f), (g) and
(h) and the rules of the Depository; the exchange,  transfer and registration of
transfer of  Individual  Certificates  or  beneficial  interests  in the Private
Global Certificates shall be subject to the following restrictions:

       (i)    Transfers between Holders of Individual Certificates. With respect
              to the  transfer  and  registration  of transfer of an  Individual
              Certificate representing an interest in the Class B-7, Class B-7H,
              Class  V-1,  Class  V-2,  Class R or  Class LR  Certificates  to a
              transferee  that  takes  delivery  in the  form  of an  Individual
              Certificate:

               (A)  The Certificate  Registrar shall register the transfer of an
                    Individual  Certificate  if the requested  transfer is being
                    made  by a  transferee  who  has  provided  the  Certificate
                    Registrar   with   an   Investment   Representation   Letter
                    substantially   in  the  form  of  Exhibit  D-1  hereto  (an
                    "Investment  Representation Letter"), to the effect that the
                    transfer is being made to a Qualified Institutional Buyer in
                    accordance with Rule 144A;

               (B)  The Certificate  Registrar shall register the transfer of an
                    Individual  Certificate  pursuant to  Regulation S after the
                    expiration of the  Restricted  Period if (1) the  transferor
                    has provided the  Certificate  Registrar with a Regulation S
                    Transfer Certificate  substantially in the form of Exhibit I
                    hereto (a "Regulation S Transfer Certificate"),  and (2) the
                    transferee   furnishes  to  the  Certificate   Registrar  an
                    Investment Representation Letter; and

     (C) The Certificate  Registrar shall register the transfer of an Individual
Certificate  if  prior  to  the  transfer  such  transferee   furnishes  to  the
Certificate Registrar (1) an Investment Representation Letter to the effect that
the  transfer  is being made to an  Institutional  Accredited  Investor or to an
Affiliated Person in accordance with an applicable  exemption under the Act, and
(2) an Opinion of Counsel  acceptable  to the  Certificate  Registrar  that such
transfer is in compliance with the Act;

              and, in each case, the  Certificate  Registrar shall register the
              transfer  of an  Individual  Certificate  only  if  prior  to the
              transfer the transferee furnishes to the Certificate  Registrar a
              written  undertaking by the transferor to reimburse the Trust for
              any  costs  incurred  by  it  in  connection  with  the  proposed
              transfer.  In  addition,  the  Certificate  Registrar  may,  as a
              condition of the  registration of any such transfer,  require the
              transferor to furnish such other certificates,  legal opinions or
              other   information   (at  the   transferor's   expense)  as  the
              Certificate  Registrar may reasonably require to confirm that the
              proposed transfer is being made pursuant to an exemption from, or
              in a transaction not subject to, the registration requirements of
              the Act and other applicable laws.

       (ii)   Transfers within the Private Global Certificates.  Notwithstanding
              any provision to the contrary herein,  so long as a Private Global
              Certificate remains outstanding and is held by or on behalf of the
              Depository, transfers within the Private Global Certificates shall
              only be made in accordance with this Section 5.02(c)(ii).

               (A)  Rule  144A  Global   Certificate   to  Regulation  S  Global
                    Certificate  During the  Restricted  Period.  If, during the
                    Restricted  Period,  a Beneficial  Owner of an interest in a
                    Rule 144A Global  Certificate wishes at any time to transfer
                    its beneficial interest in such Rule 144A Global Certificate
                    to a Person who wishes to take delivery  thereof in the form
                    of a beneficial  interest in the related Regulation S Global
                    Certificate,  such  Beneficial  Owner may,  in  addition  to

                    for an equivalent  beneficial  interest in such Regulation S
                    Global  Certificate only upon compliance with the provisions
                    of  this  Section   5.02(c)(ii)(A).   Upon  receipt  by  the

                    Global  Certificate to be  transferred,  (2) a written order
                    given  in   accordance   with  the   Applicable   Procedures

                    to be  debited  for,  such  beneficial  interest,  and (3) a
                    certificate  in the form of  Exhibit  J hereto  given by the
                    Beneficial Owner of such interest, the Certificate Registrar
                    shall instruct the Depository or the Certificate  Custodian,
                    as applicable,  to reduce the  Denomination of the Rule 144A
                    Global  Certificate  by the  Denomination  of the beneficial
                    interest  in  the  Rule  144A  Global  Certificate  to be so
                    transferred  and,  concurrently  with  such  reduction,   to

                    S Global  Certificate by the aggregate  Denomination  of the
                    beneficial  interest in the Regulation S Global  Certificate
                    to be transferred, and, concurrently with such reduction, to
                    increase   the   Denomination   of  the  Rule  144A   Global
                    Certificate by the aggregate  Denomination of the beneficial
                    interest in the  Regulation  S Global  Certificate  to be so
                    transferred,  and to credit or cause to be  credited  to the
                    account  of the  Person  specified  in such  instructions  a
                    beneficial  interest  in such Rule 144A  Global  Certificate
                    having a  Denomination  equal  to the  amount  by which  the
                    Denomination  of the  Regulation  S Global  Certificate  was
                    reduced upon such transfer.

       (iii)  Transfers  from the  Private  Global  Certificates  to  Individual
              Certificates.   Any  and  all  transfers  from  a  Private  Global
              Certificate  to a transferee  wishing to take delivery in the form
              of an Individual  Certificate  will require the transferee to take
              delivery  subject  to the  restrictions  on the  transfer  of such
              Individual  Certificate  described in the Securities  Legend,  and
              such  transferee  agrees  that it will  transfer  such  Individual
              Certificate only as provided therein and herein.  No such transfer
              shall be made and the Certificate Registrar shall not register any
              such transfer unless such transfer is made in accordance with this
              Section 5.02(c)(iii).

               (A)  Transfers  of a  beneficial  interest  in a  Private  Global
                    Certificate  to an  Institutional  Accredited  Investor will
                    require  delivery in the form of an  Individual  Certificate
                    and the  Certificate  Registrar shall register such transfer
                    only  upon   compliance   with  the  provisions  of  Section
                    5.02(c)(i)(C).

               (B)  Transfers  of a  beneficial  interest  in a  Private  Global
                    Certificate  to  a  Qualified   Institutional   Buyer  or  a
                    Regulation S Investor  wishing to take  delivery in the form
                    of an  Individual  Certificate  will  be  registered  by the
                    Certificate   Registrar  only  upon   compliance   with  the
                    provisions of Sections 5.02(c)(i)(A) and (B), respectively.

               (C)  Notwithstanding  the foregoing,  no transfer of a beneficial
                    interest  in  a  Regulation  S  Global   Certificate  to  an
                    Individual  Certificate  pursuant to subparagraph  (B) above
                    shall be made  prior  to the  expiration  of the  Restricted
                    Period.

                    Upon  acceptance  for  exchange or transfer of a beneficial
              interest  in  a  Private  Global  Certificate  for  an  Individual
              Certificate,  as provided herein, the Certificate  Registrar shall
              endorse on the  schedule  affixed to the  related  Private  Global
              Certificate (or on a continuation of such schedule affixed to such
              Private Global Certificate and made a part thereof) an appropriate
              notation  evidencing  the date of such  exchange or transfer and a
              decrease in the  Denomination  of such Private Global  Certificate
              equal to the Denomination of such Individual Certificate issued in
              exchange  therefor or upon  transfer  thereof.  Unless  determined
              otherwise  by  the   Certificate   Registrar  in  accordance  with
              applicable law, an Individual  Certificate issued upon transfer of
              or  exchange  for a  beneficial  interest  in the  Private  Global
              Certificate shall bear the Securities Legend.

       (iv)   Transfers  of  Individual   Certificates  to  the  Private  Global
              Certificates.  If a Holder of an Individual  Certificate wishes at
              any time to transfer  such  Certificate  to a Person who wishes to
              take delivery thereof in the form of a beneficial  interest in the
              related  Regulation S Global  Certificate or the related Rule 144A
              Global  Certificate,   such  transfer  may  be  effected  only  in
              accordance  with  the  Applicable   Procedures  and  this  Section
              5.02(c)(iv).  Upon  receipt by the  Certificate  Registrar  at the
              Corporate  Trust Office of (1) the  Individual  Certificate  to be
              transferred  with an assignment  and transfer  pursuant to Section
              5.02(a),  (2) written  instructions  given in accordance  with the
              Applicable   Procedures   from  an  Agent  Member   directing  the
              Certificate Registrar to credit or cause to be credited to another
              specified  Agent  Member's  account a beneficial  interest in such
              Regulation  S  Global   Certificate   or  such  Rule  144A  Global
              Certificate,  as the  case  may  be,  in an  amount  equal  to the
              Denomination  of the Individual  Certificate to be so transferred,
              (3) a  written  order  given in  accordance  with  the  Applicable
              Procedures  containing  information  regarding  the account of the
              Agent  Member  and,  in the  case  of  any  transfer  pursuant  to
              Regulation S, the Euroclear or Cedel account,  as the case may be,
              to be  credited  with  such  beneficial  interest,  and (4) (x) an
              Investment  Representation  Letter  from the  transferee  and,  if
              delivery  is to be taken in the form of a  beneficial  interest in
              the  Regulation  S Global  Certificate,  a  Regulation  S Transfer
              Certificate   from   the   transferor   or   (y)   an   Investment
              Representation  Letter from the transferee to the effect that such
              transferee is a Qualified Institutional Buyer if delivery is to be
              taken in the form of a beneficial interest in the Rule 144A Global
              Certificate,   the   Certificate   Registrar   shall  cancel  such
              Individual  Certificate,  execute  and  deliver  a new  Individual
              Certificate for the Denomination of the Individual Certificate not
              so  transferred,  registered  in the  name  of the  Holder  or the
              Holder's  transferee  (as  instructed  by  the  Holder),  and  the
              Certificate   Registrar  shall  instruct  the  Depository  as  the
              Certificate Custodian, as applicable, to increase the Denomination
              of the  Regulation  S Global  Certificate  or the Rule 144A Global
              Certificate,  as the  case  may  be,  by the  Denomination  of the
              Individual  Certificate  to be so  transferred,  and to  credit or
              cause to be  credited to the  account of the Person  specified  in
              such  instructions  who,  in  the  case  of  any  increase  in the
              Regulation  S Global  Certificate  during the  Restricted  Period,
              shall be an Agent  Member  acting for or on behalf of Euroclear or
              Cedel, or both, as the case may be, a  corresponding  Denomination
              of the Rule 144A Global  Certificate  or the  Regulation  S Global
              Certificate, as the case may be.

                    It  is  the   intent  of  the   foregoing   that  under  no
              circumstances may an Institutional Accredited Investor that is not
              a  Qualified  Institutional  Buyer take  delivery in the form of a
              beneficial interest in a Private Global Certificate.

       (v)    All Transfers.  An exchange of a beneficial  interest in a Private
              Global Certificate for an Individual  Certificate or Certificates,
              an exchange of an Individual  Certificate  or  Certificates  for a
              beneficial  interest  in  a  Private  Global  Certificate  and  an
              exchange of an Individual  Certificate or Certificates for another
              Individual  Certificate or Certificates (in each case,  whether or
              not such exchange is made in anticipation of subsequent  transfer,
              and, in the case of the Private  Global  Certificates,  so long as
              the Private Global Certificates remain outstanding and are held by
              or on behalf of the  Depository),  may be made only in  accordance
              with this  Section  5.02 and in  accordance  with the rules of the
              Depository and Applicable Procedures.

     (d) If Certificates  are issued upon the transfer,  exchange or replacement
of Certificates  not bearing the Securities  Legend,  the Certificates so issued
shall not bear the  Securities  Legend.  If  Certificates  are  issued  upon the
transfer, exchange or replacement of Certificates bearing the Securities Legend,
or if a request is made to remove the Securities  Legend on a  Certificate,  the
Certificates  so issued  shall bear the  Securities  Legend,  or the  Securities
Legend  shall not be removed,  as the case may be,  unless there is delivered to
the  Certificate  Registrar  such  satisfactory  evidence,  which may include an
Opinion of Counsel (at the expense of the party  requesting  the removal of such
legend)  familiar  with United  States  securities  laws,  as may be  reasonably
required by the Certificate  Registrar,  that neither the Securities  Legend nor
the  restrictions  on  transfers  set forth  therein are required to ensure that
transfers of any Certificate comply with the provisions of Rule 144A or Rule 144
under the Act or that such Certificate is not a "restricted security" within the
meaning of Rule 144 under the Act. Upon provision of such satisfactory evidence,
the Certificate  Registrar shall execute and deliver a Certificate that does not
bear the Securities Legend.

     (e) Subject to the  restrictions on transfer and exchange set forth in this
Section 5.02, the Holder of any Individual  Certificate may transfer or exchange
the same in  whole  or in part  (with a  denomination  equal  to any  authorized
denomination) by surrendering  such Certificate at the Corporate Trust Office or
at the office of any transfer agent  appointed as provided under this Agreement,
together with an instrument of assignment or transfer (executed by the Holder or
its duly authorized  attorney),  in the case of transfer,  and a written request
for exchange,  in the case of exchange.  Following a proper request for transfer
or exchange,  the Certificate Registrar shall, within five Business Days of such
request if made at such  Corporate  Trust Office or within ten Business  Days if
made at the office of a transfer agent (other than the  Certificate  Registrar),
execute  and  deliver  at the  Corporate  Trust  Office or at the office of such
transfer  agent, as the case may be, to the transferee (in the case of transfer)
or Holder (in the case of  exchange) or send by first Class mail (at the risk of
the  transferee  in the case of transfer or Holder in the case of  exchange)  to
such  address as the  transferee  or Holder,  as  applicable,  may  request,  an
Individual  Certificate  or  Certificates,  as the case may require,  for a like
aggregate  Denomination  and in such  Denomination  or  Denominations  as may be
requested.   The  presentation  for  transfer  or  exchange  of  any  Individual
Certificate  shall not be valid unless made at the Corporate  Trust Office or at
the office of a transfer agent by the registered  Holder in person, or by a duly
authorized attorney-in-fact. The Certificate Registrar may decline to accept any
request for an exchange or registration  of transfer of any  Certificate  during
the period of fifteen days preceding any Distribution Date.

     (f) An Individual  Certificate (other than an Individual Certificate issued
in exchange for a beneficial interest in a Public Global Certificate pursuant to
Section 5.01) or a beneficial  interest in a Private Global Certificate may only
be transferred to Eligible  Investors,  as described herein. In the event that a
Responsible  Officer of the  Certificate  Registrar  becomes  aware that such an
Individual Certificate or beneficial interest in a Private Global Certificate is
being held by or for the benefit of a Person who is not an Eligible Investor, or
that such holding is unlawful  under the laws of a relevant  jurisdiction,  then
the  Certificate  Registrar  shall  have the  right to void  such  transfer,  if
permitted  under  applicable  law,  or to  require  the  investor  to sell  such
Individual Certificate or beneficial interest in a Private Global Certificate to
an Eligible Investor within fourteen days after notice of such determination and
each  Certificateholder  by  its  acceptance  of a  Certificate  authorizes  the
Certificate Registrar to take such action.

     (g) Subject to the provisions of this Section 5.02  regarding  transfer and
exchange,  transfers of the Global Certificates shall be limited to transfers of
such  Global  Certificates  in  whole,  but  not in  part,  to  nominees  of the
Depository or to a successor of the Depository or such successor's nominee.

     (h) No fee or service charge shall be imposed by the Certificate  Registrar
for its services in respect of any registration of transfer or exchange referred
to in this Section 5.02 other than for  transfers  to  Institutional  Accredited
Investors,   as  provided  herein.   In  connection  with  any  transfer  to  an
Institutional Accredited Investor, the transferor shall reimburse the Trust Fund
for any  costs  (including  the cost of the  Certificate  Registrar's  counsel's
review of the documents and any legal  opinions,  submitted by the transferor or
transferee  to the  Certificate  Registrar as provided  herein)  incurred by the
Certificate  Registrar  in  connection  with  such  transfer.   The  Certificate
Registrar may require  payment by each  transferor of a sum  sufficient to cover
any tax,  expense or other  governmental  charge payable in connection  with any
such transfer.

     (i) Subject to Section  5.02(e),  transfers  of the Class B-7,  Class B-7H,
Class V-1,  Class  V-2,  Class R and Class LR  Certificates  may be made only in
accordance with this Section 5.02(i).  The Certificate  Registrar shall register
the transfer of a Class B-7, Class B-7H,  Class V-1, Class V-2, Class R or Class
LR Certificate only if (x) the transferor has advised the Certificate  Registrar
in  writing  that  such   Certificate  is  being   transferred  to  a  Qualified
Institutional  Buyer,  an  Affiliated  Person  or  an  Institutional  Accredited
Investor  and (y)  prior  to  such  transfer  the  transferee  furnishes  to the
Certificate  Registrar an Investment  Representation  Letter.  In addition,  the
Certificate  Registrar  may as a  condition  of  the  registration  of any  such
transfer  require the  transferor  to furnish such other  certifications,  legal
opinions or other information (at the transferor's expense) as it may reasonably
require to confirm  that the  proposed  transfer  is being made  pursuant  to an
exemption  from,  or  in  a  transaction   not  subject  to,  the   registration
requirements of the Act and other applicable laws.

     (j) Neither the Depositor,  the Servicer,  the Trustee nor the  Certificate
Registrar is obligated to register or qualify the Class B-7,  Class B-7H,  Class
V-1,  Class  V-2,  Class R or Class LR  Certificates  under the Act or any other
securities law or to take any action not otherwise required under this Agreement
to  permit  the  transfer  of  such   Certificates   without   registration   or
qualification.  Any Certificateholder  desiring to effect such a transfer shall,
and does hereby agree to, indemnify the Depositor, the Servicer, the Trustee and
the  Certificate  Registrar,  against any loss,  liability  or expense  that may
result if the transfer is not so exempt or is not made in  accordance  with such
federal and state laws.

     (k) No transfer of any Class A-2,  Class A-3,  Class A-4,  Class A-5, Class
B-1,  Class B-2,  Class B-3,  Class B-4,  Class B-5, Class B-6, Class B-7, Class
B-7H, Class V-1, Class V-2, Class R or Class LR Certificate (each, a "Restricted
Certificate")  shall be made to (i) an  employee  benefit  plan  subject  to the
fiduciary responsibility  provisions of ERISA, or Section 4975 of the Code, or a
governmental  plan subject to any federal,  state or local law ("Similar  Law"),
which is to a material extent,  similar to the foregoing  provisions of ERISA or
the Code (collectively,  a "Plan") or (ii) a collective investment fund in which
a Plan is  invested,  an  insurance  company  that is using  the  assets  of any
insurance company separate account or general account in which the assets of any
such Plan are invested (or which are deemed pursuant to ERISA or any Similar Law
to include  assets of Plans) to acquire any such  Restricted  Certificate or any
other  Person  acting on  behalf of any Plan or using the  assets of any Plan to
acquire any such Restricted Certificate, other than (with respect to transfer of
Restricted  Certificates  other  than the  Class  V-1,  Class  V-2 and  Residual
Certificates) an insurance company using the assets of its general account under
circumstances  whereby  such  transfer  to  such  insurance  company  would  not
constitute a "prohibited  transaction"  within the meaning of Section 406 or 407
of ERISA,  Section 4975 of the Code,  or a materially  similar  characterization
under any Similar Law. Each prospective  transferee of a Restricted  Certificate
shall either (1) deliver to the  Depositor,  the  Certificate  Registrar and the
Trustee,  a transfer  or  representation  letter,  substantially  in the form of
Exhibit D-2 hereto,  stating  that the  prospective  transferee  is not a Person
referred to in (i) or (ii) above or (2) in the event the  transferee  is such an
entity  specified  in (i) or  (ii)  above,  except  in the  case  of a  Residual
Certificate, which may not be transferred unless the transferee represents it is
not such an entity,  such entity shall provide an Opinion of Counsel in form and
substance satisfactory to the Certificate Registrar that the purchase or holding
of the  certificates  by or on behalf of a plan will not result in the assets of
the  trust  being  deemed  to be "plan  assets"  and  subject  to the  fiduciary
responsibility  provisions of ERISA or the prohibited  transaction provisions of
ERISA and the Code or Similar Law, will not constitute or result in a prohibited
transaction within the meaning of Section 406 or 407 of ERISA or Section 4975 of
the  Code,  and will  not  subject  the  Servicer,  the  Special  Servicer,  the
Depositor,  the  Trustee  or the  Certificate  Registrar  to any  obligation  or
liability. Neither the Trustee, the Servicer nor the Certificate Registrar shall
register a Class R or Class LR  Certificate  in any  Person's  name  unless such
Person has  provided  the  letter  referred  to in clause  (1) of the  preceding
sentence.  The transferee of a beneficial  interest in a Global Certificate that
is a Restricted  Certificate  shall be deemed to represent that it is not a Plan
or a Person  acting on  behalf  of any Plan or using  the  assets of any Plan to
acquire  such  interest  other than (with  respect to  transfers  of  beneficial
interests in Global  Certificates  which are Restricted  Certificates other than
the Class V-1, Class V-2 and Residual  Certificates) an insurance  company using
the assets of its general account under  circumstances  whereby such transfer to
such insurance  company would not constitute a "prohibited  transaction"  within
the  meaning  of Section  406 or 407 of ERISA,  Section  4975 of the Code,  or a
materially  similar  characterization  under any Similar  Law. Any transfer of a
Restricted  Certificate that would violate or result in a prohibited transaction
under ERISA or Section 4975 of the Code shall be deemed absolutely null and void
ab initio.

     (l) Each Person who has or acquires any Ownership  Interest shall be deemed
by the acceptance or acquisition of such Ownership Interest to have agreed to be
bound by the following  provisions  and the rights of each Person  acquiring any
Ownership Interest are expressly subject to the following provisions:

       (i)    Each Person acquiring or holding any Ownership Interest shall be a
              Permitted  Transferee and shall not acquire or hold such Ownership
              Interest as agent (including a broker, nominee or other middleman)
              on behalf of any Person  that is not a Permitted  Transferee.  Any
              such Person shall promptly notify the Certificate Registrar of any
              change or  impending  change in its  status  (or the status of the
              beneficial  owner  of  such  Ownership  Interest)  as a  Permitted
              Transferee.  Any  acquisition  described in the first  sentence of
              this Section 5.02(l) by a Person who is not a Permitted Transferee
              or by a Person  who is acting as an agent of a Person who is not a
              Permitted  Transferee  shall  be void  and of no  effect,  and the
              immediately  preceding owner who was a Permitted  Transferee shall
              be  restored  to  registered  and  beneficial   ownership  of  the
              Ownership Interest as fully as possible.

       (ii)   No Ownership  Interest may be  Transferred,  and no such  Transfer
              shall be  registered  in the  Certificate  Register,  without  the
              express  written  consent of the  Certificate  Registrar,  and the
              Certificate  Registrar shall not recognize the Transfer,  and such
              proposed  Transfer  shall not be  effective,  without such consent
              with respect thereto.  In connection with any proposed Transfer of
              any Ownership  Interest,  the  Certificate  Registrar  shall, as a
              condition to such consent,  (x) require delivery to it in form and
              substance  satisfactory to it, and the proposed  transferee  shall
              deliver  to  the   Certificate   Registrar  and  to  the  proposed
              transferor  an affidavit  in  substantially  the form  attached as
              Exhibit C-1 (a "Transferee  Affidavit") of the proposed transferee
              (A) that such proposed  transferee is a Permitted  Transferee  and
              (B) stating that (i) the proposed transferee historically has paid
              its  debts  as they  have  come  due and  intends  to do so in the
              future,  (ii) the proposed  transferee  understands  that,  as the
              holder  of an  Ownership  Interest,  it may incur  liabilities  in
              excess of cash flows generated by the residual interest, (iii) the
              proposed  transferee  intends to pay taxes associated with holding
              the  Ownership  Interest  as they become  due,  (iv) the  proposed
              transferee will not transfer the Ownership  Interest to any Person
              that does not provide a  Transferee  Affidavit  or as to which the
              proposed transferee has actual knowledge that such Person is not a
              Permitted Transferee or is acting as an agent (including a broker,
              nominee or other  middleman)  for a Person that is not a Permitted
              Transferee, and (v) the proposed transferee expressly agrees to be
              bound by and to abide by the  provisions  of this Section  5.02(l)
              and (y) other than in connection with the initial  issuance of the
              Class R and Class LR  Certificates,  require a statement  from the
              proposed transferor  substantially in the form attached as Exhibit
              C-2 (the "Transferor Letter"), that the proposed transferor has no
              actual  knowledge that the proposed  transferee is not a Permitted
              Transferee and has no actual  knowledge or reason to know that the
              proposed   transferee's   statements  in  the  preceding   clauses
              (x)(B)(i) or (iii) are false.

       (iii)  Notwithstanding  the  delivery  of  a  Transferee  Affidavit  by a
              proposed  transferee  under  clause (ii) above,  if a  Responsible
              Officer of the Certificate Registrar has actual knowledge that the
              proposed transferee is not a Permitted Transferee,  no Transfer to
              such  proposed  transferee  shall be  effected  and such  proposed
              Transfer  shall not be  registered  on the  Certificate  Register;
              provided,  however,  that the  Certificate  Registrar shall not be
              required to conduct any  independent  investigation  to  determine
              whether a proposed transferee is a Permitted Transferee.

     Upon notice to the Certificate Registrar that there has occurred a Transfer
to any Person that is a Disqualified Organization or an agent thereof (including
a broker, nominee, or middleman) in contravention of the foregoing restrictions,
and in any event not later than 60 days after a request for information from the
transferor of such Ownership Interest,  or such agent, the Certificate Registrar
and the Trustee agree to furnish to the IRS and the transferor of such Ownership
Interest or such agent such information  necessary to the application of Section
860E(e) of the Code as may be required by the Code,  including,  but not limited
to, the present value of the total anticipated excess inclusions with respect to
such Class R or Class LR Certificate (or portion thereof) for periods after such
Transfer.  At the election of the  Certificate  Registrar  and the Trustee,  the
Certificate  Registrar and the Trustee may charge a reasonable fee for computing
and furnishing  such  information to the transferor or to such agent referred to
above;  provided,  however,  that such Persons shall in no event be excused from
furnishing such information.

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

     If  (i)  any  mutilated  Certificate  is  surrendered  to  the  Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction,  loss or theft of any Certificate,  and (ii) there is delivered
to the Certificate Registrar such security or indemnity as may be required by it
to save it, the  Trustee  and the  Servicer  harmless,  then,  in the absence of
actual knowledge by a Responsible Officer of the Certificate Registrar that such
Certificate  has been  acquired  by a bona fide  purchaser,  the  Trustee or the
Authenticating   Agent  shall  execute  and  authenticate  and  the  Certificate
Registrar  shall  deliver,  in  exchange  for or in lieu of any such  mutilated,
destroyed,  lost or stolen Certificate,  a new Certificate of the same Class and
of like tenor and Percentage Interest.  Upon the issuance of any new Certificate
under this Section 5.03, the Certificate  Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation  thereto and any other expenses  (including the fees and expenses of
the Certificate  Registrar)  connected  therewith.  Any replacement  Certificate
issued pursuant to this Section 5.03 shall constitute  complete and indefeasible
evidence of ownership  of the  corresponding  interest in the Trust Fund,  as if
originally  issued,  whether or not the lost,  stolen or  destroyed  Certificate
shall be found at any time.

     SECTION 5.04. Appointment of Paying Agent.

     The  Trustee  may  appoint  a  Paying  Agent  for  the  purpose  of  making
distributions to Certificateholders  pursuant to Section 4.01. The Trustee shall
cause such Paying Agent,  if other than the Trustee or the Servicer,  to execute
and deliver to the Servicer and the Trustee an  instrument  in which such Paying
Agent shall agree with the  Servicer and the Trustee that such Paying Agent will
hold all sums held by it for the payment to  Certificateholders in trust for the
benefit of the  Certificateholders  entitled  thereto  until such sums have been
paid to the  Certificateholders or disposed of as otherwise provided herein. The
initial Paying Agent shall be the Trustee.  Except for LaSalle National Bank, as
the  initial  Paying  Agent,  the Paying  Agent  shall at all times be an entity
having a long-term  unsecured debt rating of at least "AA" by Fitch, DCR and S&P
and "Aa2" by Moody's, or shall be otherwise acceptable to each Rating Agency.

     SECTION 5.05. Access to Certificateholders' Names and Addresses.

     (a) If any  Certificateholder or the Servicer or Sub-Servicer (for purposes
of this Section  5.05,  an  "Applicant")  applies in writing to the  Certificate
Registrar, and such application states that the Applicant desires to communicate
with other Certificateholders,  the Certificate Registrar shall furnish or cause
to be  furnished  to such  Applicant  a list of the names and  addresses  of the
Certificateholders  as of the most  recent  Record  Date,  at the expense of the
Applicant,  in the case of any Certificateholder and the expense of the Trust in
the case of the Servicer or Sub-Servicer.

     (b) Every  Certificateholder,  by  receiving  and holding its  Certificate,
agrees with the Trustee that the Trustee and the Certificate Registrar shall not
be held accountable in any way by reason of the disclosure of any information as
to the names and addresses of the  Certificateholders  hereunder,  regardless of
the source from which such information was derived.

     SECTION 5.06. Actions of Certificateholders.

     (a) Any request, demand, authorization,  direction, notice, consent, waiver
or  other  action   provided  by  this   Agreement  to  be  given  or  taken  by
Certificateholders  may be embodied in and evidenced by one or more  instruments
of substantially similar tenor signed by such Certificateholders in person or by
agent  duly  appointed  in  writing;  and except as herein  otherwise  expressly
provided, such action shall become effective when such instrument or instruments
are  delivered  to the Trustee  and,  when  required,  to the  Depositor  or the
Servicer.  Proof of execution of any such instrument or of a writing  appointing
any such  agent  shall be  sufficient  for any  purpose  of this  Agreement  and
conclusive in favor of the Trustee,  the Depositor and the Servicer,  if made in
the manner provided in this Section.

     (b) The fact and date of the execution by any Certificateholder of any such
instrument or writing may be proved in any  reasonable  manner which the Trustee
deems sufficient.

     (c) Any request, demand, authorization,  direction, notice, consent, waiver
or other act by a Certificateholder shall bind every Holder of every Certificate
issued upon the registration of transfer  thereof or in exchange  therefor or in
lieu  thereof,  in  respect of  anything  done,  or  omitted to be done,  by the
Trustee,  the  Depositor  or the  Servicer in reliance  thereon,  whether or not
notation of such action is made upon such Certificate.

     (d) The Trustee or Certificate  Registrar may require such additional proof
of any matter referred to in this Section 5.06 as it shall deem necessary.

                                   ARTICLE VI

                           THE DEPOSITOR, THE SERVICER
                            AND THE SPECIAL SERVICER

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

     The Depositor,  the Servicer and the Special  Servicer each shall be liable
in  accordance  herewith  only to the  extent  of the  obligations  specifically
imposed by this Agreement.

     SECTION 6.02.   Merger or Consolidation of the Servicer.

     Subject to the following  paragraph,  the Servicer will keep in full effect
its existence,  rights and good standing as a limited partnership under the laws
of the State of Delaware and will not  jeopardize  its ability to do business in
each  jurisdiction  in which the Mortgaged  Properties are located or to protect
the validity and  enforceability  of this Agreement,  the Certificates or any of
the Mortgage Loans and to perform its respective duties under this Agreement.

     The  Servicer  may be merged or  consolidated  with or into any Person,  or
transfer all or substantially all of its assets to any Person, in which case any
Person  resulting from any merger or consolidation to which it shall be a party,
or any Person succeeding to its business, shall be the successor of the Servicer
hereunder,  and shall be deemed to have  assumed all of the  liabilities  of the
Servicer hereunder, if each of the Rating Agencies has confirmed in writing that
such merger or  consolidation  or transfer of assets and  succession,  in and of
itself,  will not cause a downgrade,  qualification  or  withdrawal  of the then
current ratings assigned by such Rating Agency to any Class of Certificates.

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

     (a) Neither the Depositor,  the Servicer,  the Special  Servicer nor any of
the directors, officers, employees or agents of the Depositor or the Servicer or
the  Special  Servicer  shall be under any  liability  to the Trust  Fund or the
Certificateholders  for any action taken,  or for refraining  from the taking of
any action, in good faith pursuant to this Agreement, or for errors in judgment;
provided,  however,  that this provision  shall not protect the Depositor or the
Servicer  or the  Special  Servicer  or any such  Person  against  any breach of
warranties or representations  made herein, or against any liability which would
otherwise  be  imposed  by reason of willful  misconduct,  bad  faith,  fraud or
negligence in the  performance  of duties or by reason of reckless  disregard of
obligations  or duties  hereunder.  The  Depositor,  the  Servicer,  the Special
Servicer and any  director,  officer,  employee or agent of the  Depositor,  the
Servicer or the Special  Servicer  may rely in good faith on any document of any
kind which,  prima facie, is properly  executed and submitted by any appropriate
Person respecting any matters arising  hereunder.  The Depositor,  the Servicer,
the  Special  Servicer  and any  director,  officer,  employee  or  agent of the
Depositor or the Servicer or the Special  Servicer shall be indemnified and held
harmless by the Trust Fund  against any loss,  liability  or expense  (including
legal fees and  expenses)  (i)  incurred  in  connection  with any legal  action
relating to this Agreement or the Certificates,  other than any loss,  liability
or  expense  incurred  by reason of  willful  misconduct,  bad  faith,  fraud or
negligence (or in the case of the Servicer or the Special Servicer, by reason of
any specific  liability  imposed for a breach of the Servicing  Standard) in the
performance  of  duties  hereunder  or  by  reason  of  reckless   disregard  of
obligations or duties hereunder, in each case by the Person being indemnified or
(ii) imposed by any taxing  authority if such loss,  liability or expense is not
specifically  reimbursable pursuant to the terms of this Agreement.  Neither the
Depositor  nor  the  Servicer  nor the  Special  Servicer  shall  be  under  any
obligation to appear in, prosecute or defend any legal action unless such action
is related to its respective duties under this Agreement and in its opinion does
not expose it to any expense or liability; provided, however, that the Depositor
or the Servicer or the Special  Servicer  may in its  discretion  undertake  any
action  related to its  obligations  hereunder  which it may deem  necessary  or
desirable  with  respect  to this  Agreement  and the  rights  and duties of the
parties hereto and the interests of the  Certificateholders  hereunder.  In such
event,  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  Servicer  and the  Special  Servicer  shall be  entitled  to be
reimbursed  therefor from the Collection  Account as provided in Section 3.06 of
this Agreement.

     SECTION  6.04.  Limitation on  Resignation  of the Servicer and the Special
                     Servicer; Termination of the Servicer and the Special
                     Servicer.

     (a) The  Servicer  and the Special  Servicer  may assign  their  respective
rights and delegate their respective duties and obligations under this Agreement
in  connection  with the sale or  transfer  of a  substantial  portion  of their
mortgage  servicing  or  asset  management  portfolio,  provided  that:  (i) the
purchaser or transferee  accepting  such  assignment and delegation (A) shall be
satisfactory  to the Trustee and to the  Depositor,  (B) shall be an established
mortgage finance institution, bank or mortgage servicing institution,  organized
and  doing  business  under the laws of any  state of the  United  States or the
District  of  Columbia,  authorized  under such laws to perform  the duties of a
servicer of mortgage loans or a Person resulting from a merger, consolidation or
succession that is permitted under Section 6.02, (C) shall be acceptable to each
Rating Agency as confirmed by a letter from each Rating Agency  delivered to the
Trustee  that  such  assignment  or  delegation  will  not  cause  a  downgrade,
withdrawal or qualification of the then current ratings of the Certificates, and
(D) shall execute and deliver to the Trustee an agreement, in form and substance
reasonably  satisfactory  to the Trustee,  which  contains an assumption by such
Person of the due and punctual  performance  and observance of each covenant and
condition to be performed or observed by the Servicer  under this Agreement from
and after the date of such  agreement;  (ii) as  confirmed by a letter from each
Rating Agency  delivered to the Trustee,  each Rating Agency's rating or ratings
of the Regular Certificates in effect immediately prior to such assignment, sale
or transfer will not be  qualified,  downgraded or withdrawn as a result of such
assignment,  sale or transfer;  (iii) the Servicer or the Special Servicer shall
not be released from its  obligations  under this  Agreement that arose prior to
the effective date of such  assignment  and delegation  under this Section 6.04;
and (iv) the  rate at  which  the  Servicer  Compensation  or  Special  Servicer
Compensation,  as applicable (or any component  thereof) is calculated shall not
exceed  the  rate  then  in  effect.  Upon  acceptance  of such  assignment  and
delegation,  the  purchaser or  transferee  shall be the  successor  Servicer or
Special Servicer, as applicable, hereunder.

     (b) Except as provided in this Section  6.04,  the Servicer and the Special
Servicer shall not resign from their  respective  obligations  and duties hereby
imposed on them except upon  determination  that such  duties  hereunder  are no
longer permissible under applicable law. Any such  determination  permitting the
resignation of the Servicer or the Special  Servicer,  as  applicable,  shall be
evidenced by an Opinion of Counsel  (obtained  at the  resigning  Servicer's  or
Special Servicer's expense) to such effect delivered to the Trustee.

     (c) The  Depositor,  upon paying the  Servicer a negotiated  fee,  shall be
permitted  to remove  the  Servicer  provided  that (i) each  Rating  Agency has
confirmed  in writing  that such  removal and  replacement  will not result in a
downgrade,  qualification  or  withdrawal  of the then  current  ratings by such
Rating Agency to any Class of  Certificates  and (ii) the  replacement  Servicer
shall be a servicing  company that is an Affiliate of the  Depositor;  provided,
however,  that such replacement  Servicer will not directly service or specially
service any Mortgage  Loan in which an Affiliate of the  Depositor  has a common
equity  interest in the  related  Borrower or its  Affiliate.  If the  Depositor
removes the Servicer pursuant to the preceding sentence, the Depositor shall pay
for all costs and expenses that would otherwise be incurred by the Trust Fund in
connection with such removal and replacement. Without limiting the generality of
the succeeding  paragraph,  no such removal shall be effective  unless and until
(i) the  Servicer  or the  Special  Servicer  has been paid any unpaid  Servicer
Compensation  or Special  Servicer  Compensation,  as  applicable,  unreimbursed
Advances  (including  Advance  Interest Amounts thereon to which it is entitled)
and all other amounts to which the Servicer or the Special  Servicer is entitled
hereunder to the extent such amounts  accrue  prior to such  effective  date and
(ii) with respect to a resignation by the Servicer,  the successor  Servicer has
deposited  into the  Investment  Accounts from which  amounts were  withdrawn to
reimburse the terminated Servicer,  an amount equal to the amounts so withdrawn,
to the extent such amounts would not have been permitted to be withdrawn  except
pursuant  to this  paragraph,  in  which  case  the  successor  Servicer  shall,
immediately upon deposit, have the same right of reimbursement or payment as the
terminated  Servicer had immediately prior to its termination  without regard to
the operation of this paragraph.

     No  resignation  or removal of the  Servicer  or the  Special  Servicer  as
contemplated  by the  preceding  paragraphs  shall  become  effective  until the
Trustee or a  successor  Servicer  or Special  Servicer  shall have  assumed the
Servicer's or the Special Servicer's  responsibilities,  duties, liabilities and
obligations  hereunder.  If no  successor  Servicer or Special  Servicer  can be
obtained to perform  such  obligations  for the same  compensation  to which the
terminated  Servicer or Special  Servicer would have been  entitled,  additional
amounts payable to such successor  Servicer or Special Servicer shall be treated
as Realized Losses.

     (d) With respect to any Mortgage Loan in which an Affiliate of the Servicer
holds any subordinate  debt,  preferred equity investment or mezzanine debt of a
related Borrower or its Affiliate,  the Servicer may service such Mortgage Loan.
However,  the Servicer  shall  appoint an operating  advisor  acceptable  to the
Rating Agencies,  as evidenced by written  confirmation  that the appointment of
such  operating  advisor  will,  in  and  of  itself,  not  cause  a  downgrade,
qualification or withdrawal of the then current ratings assigned to any Class of
Certificates, who shall make all decisions with respect to the administration of
such  Mortgage  Loan  and the  related  Mortgaged  Property  including,  without
limitation,  lease  reviews and  approvals,  calculation  of and  releases  from
reserves,  modifications,  waivers and amendments of the terms thereof, releases
of collateral and transfers to special servicing. Such operating advisor will be
obligated   to   perform   such   function   in  the   best   interest   of  the
Certificateholders  in  accordance  with  the  Servicing  Standard.  The cost of
retaining such operating advisor shall be paid by the Servicer,  and no costs or
expense shall be passed through to the Trust Fund as a result of the appointment
of such operating advisor.

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

     The  Servicer and the Special  Servicer  shall  afford the  Depositor,  the
Trustee and the Rating Agencies,  upon reasonable notice, during normal business
hours  access to all  records  maintained  by it in  respect  of its  rights and
obligations   hereunder  and  access  to  its  officers   responsible  for  such
obligations.  Upon request,  the Servicer and the Special Servicer shall furnish
to the Depositor and the Trustee its most recent financial statements (or in the
case of the initial Servicer,  the financial  statements of AMRESCO,  INC. if no
separate  financial  statements have been prepared for the initial Servicer) and
such other  information  in its  possession  regarding  its  business,  affairs,
property and  condition,  financial or  otherwise as the party  requesting  such
information,  in its  reasonable  judgment,  determines  to be  relevant  to the
performance  of the  obligations  hereunder  of the  Servicer  and  the  Special
Servicer. The Depositor may, but is not obligated to, enforce the obligations of
the Servicer or the Special Servicer hereunder which are in default and may, but
is not  obligated  to,  perform,  or cause a designee to perform,  any defaulted
obligation of such Person hereunder or exercise its rights  hereunder,  provided
that the Servicer and the Special  Servicer  shall not be relieved of any of its
obligations  hereunder  by virtue of such  performance  by the  Depositor or its
designee.  In the event the Depositor or its designee undertakes any such action
it will be reimbursed by the Trust Fund from the Collection  Account as provided
in Section 3.06 and Section  6.03(a) hereof to the extent not  recoverable  from
the Servicer or Special Servicer,  as applicable.  Neither the Depositor nor the
Trustee and neither the Servicer,  with respect to the Special Servicer, nor the
Special Servicer, with respect to the Servicer, shall have any responsibility or
liability  for any  action or  failure  to act by the  Servicer  or the  Special
Servicer  and  neither  such Person is  obligated  to monitor or  supervise  the
performance  of the  Servicer or the Special  Servicer  under this  Agreement or
otherwise.  Neither the  Servicer  nor the Special  Servicer  shall be under any
obligation to disclose confidential or proprietary  information pursuant to this
Section.

     SECTION 6.06. Servicer or Special Servicer as Owner of a Certificate.

     The Servicer or an Affiliate of the Servicer or the Special  Servicer or an
Affiliate  of the Special  Servicer  may become the Holder (or with respect to a
Global Certificate, Beneficial Owner) of any Certificate with the same rights it
would have if it were not the  Servicer or the Special  Servicer or an Affiliate
thereof. If, at any time during which the Servicer or the Special Servicer or an
Affiliate  of the Servicer or the Special  Servicer is the Holder or  Beneficial
Owner of any Certificate,  the Servicer or the Special Servicer proposes to take
action  (including  for this  purpose,  omitting to take action) that (i) is not
expressly prohibited by the terms hereof and would not, in the Servicer's or the
Special Servicer's good faith judgment, violate the Servicing Standard, and (ii)
if taken,  might  nonetheless,  in the Servicer's or the Special Servicer's good
faith  judgment,  be  considered  by other  Persons  to  violate  the  Servicing
Standard,  the  Servicer or the Special  Servicer  may seek the  approval of the
Certificateholders  to such action by delivering to the Trustee a written notice
that (i)  states  that it is  delivered  pursuant  to this  Section  6.06,  (ii)
identifies the Percentage  Interest in each Class of  Certificates  beneficially
owned by the Servicer or the Special Servicer or an Affiliate of the Servicer or
the Special  Servicer,  and (iii) describes in reasonable detail the action that
the Servicer or the Special Servicer proposes to take. The Trustee, upon receipt
of such  notice,  shall  forward it to the  Certificateholders  (other  than the
Servicer  and its  Affiliates  or the Special  Servicer and its  Affiliates,  as
appropriate)  together with such  instructions for response as the Trustee shall
reasonably determine. If at any time Certificateholders holding greater than 50%
of the Voting Rights of all Certificateholders (calculated without regard to the
Certificates beneficially owned by the Servicer or its Affiliates or the Special
Servicer or its  Affiliates)  shall have  consented  in writing to the  proposal
described in the written  notice,  and if the  Servicer or the Special  Servicer
shall act as  proposed  in the written  notice,  such action  shall be deemed to
comply  with  the  Servicing   Standard.   The  Trustee  shall  be  entitled  to
reimbursement from the Servicer or the Special Servicer,  as applicable,  of the
reasonable  expenses of the Trustee incurred  pursuant to this paragraph.  It is
not the intent of the  foregoing  provision  that the  Servicer  or the  Special
Servicer be permitted to invoke the  procedure  set forth herein with respect to
routine  servicing  matters  arising  hereunder,  except in the case of  unusual
circumstances.

                                     DEFAULT

     SECTION 7.01. Events of Default.

     (a) "Servicer Event of Default", wherever used herein, means any one of the
following events:

       (i)    any failure by the Servicer to remit to the Collection  Account or
              any  failure by the  Servicer  to remit to the Trustee for deposit
              into the Distribution  Account,  Upper-Tier  Distribution Account,
              Excess Interest Distribution Account,  Interest Reserve Account or
              Default Interest  Distribution  Account, any amount required to be
              so deposited by the  Servicer  (including a P&I Advance)  pursuant
              to, and at the time specified by the terms of this Agreement; or

       (ii)   any failure on the part of the Servicer duly to observe or perform
              in any material  respect any other of the  covenants or agreements
              or the breach of any  representations or warranties on the part of
              the  Servicer   contained  in  this  Agreement   which   continues
              unremedied for a period of 30 days after the date on which written
              notice of such failure,  requiring the same to be remedied,  shall
              have been given to the  Servicer by the  Depositor or the Trustee,
              or to the  Servicer,  the Depositor and the Trustee by the Holders
              of Certificates evidencing Percentage Interests of at least 25% of
              any Class affected thereby; or

       (iii)  confirmation  in  writing  by any Rating  Agency  that  failure to
              remove the  Servicer  will,  in and of itself,  cause a downgrade,
              qualification  or withdrawal of the then current ratings  assigned
              to any Class of Certificates; or

       (iv)   a decree or order of a court or agency  or  supervisory  authority
              having  jurisdiction in the premises in an involuntary  case under
              any present or future federal or state  bankruptcy,  insolvency or
              similar law for the  appointment  of a conservator  or receiver or
              liquidator in any insolvency,  readjustment of debt, marshaling of
              assets  and  liabilities  or  similar  proceedings,   or  for  the
              winding-up or liquidation of its affairs,  shall have been entered
              against the Servicer and such decree or order shall have  remained
              in force undischarged or unstayed for a period of 60 days; or

       (v)    the Servicer shall consent to the  appointment of a conservator or
              receiver or liquidator in any  insolvency,  readjustment  of debt,
              marshaling of assets and liabilities or similar  proceedings of or
              relating   to  the   Servicer,   or  of  or  relating  to  all  or
              substantially all of its property; or

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

       (vii)  the Servicer shall fail to make any Property  Advance  required to
              be made by the Servicer  hereunder  (whether or not the Trustee or
              the Fiscal  Agent makes such  Advance),  which  failure  continues
              unremedied  for a period  of thirty  (30)  days  after the date on
              which  such  Property  Advance  was first due (or for any  shorter
              period as may be required,  if  applicable,  to avoid any lapse in
              insurance  coverage  required under any Mortgage or this Agreement
              with respect to any Mortgaged Property or to avoid any foreclosure
              or similar action with respect to any Mortgaged Property by reason
              of a failure to pay real estate taxes and  assessments  and if the
              Trustee  makes a required  Property  Advance  pursuant  to Section
              3.08(a) due to the Servicer's  failure to make a required Advance,
              such Event of Default shall occur  immediately upon such Advance);
              or

       (viii) the Servicer shall no longer be an "approved"  servicer by each of
              the Rating Agencies for mortgage pools similar to the Trust Funds;

then,  and in each and every such case,  so long as a Servicer  Event of Default
shall not have been remedied,  the Trustee may, and at the written  direction of
the Holders of at least 25% of the aggregate  Voting Rights of all  Certificates
shall, terminate the Servicer.

     In the  event  that the  Servicer  is also  the  Special  Servicer  and the
Servicer is terminated as provided in this Section 7.01, the Servicer shall also
be terminated as Special Servicer.

     (b) "Special  Servicer Event of Default",  wherever used herein,  means any
one of the following events:

       (i)    any  failure by the Special  Servicer  to remit to the  Collection
              Account  any amount  required  to be so  deposited  by the Special
              Servicer  pursuant  to and in  accordance  with the  terms of this
              Agreement; or

       (ii)   any failure on the part of the Special Servicer duly to observe or
              perform in any  material  respect  any other of the  covenants  or
              agreements or the breach of any  representations  or warranties on
              the part of the Special Servicer contained in this Agreement which
              continues  unremedied  for a period  of 30 days  after the date on
              which  written  notice of such  failure,  requiring the same to be
              remedied,  shall have been given to the  Special  Servicer  by the
              Servicer,  the  Depositor  or  the  Trustee,  or  to  the  Special
              Servicer,  the  Servicer,  the  Depositor  and the  Trustee by the
              Holders of  Certificates  evidencing  Percentage  Interests  of at
              least 25% of any Class affected thereby; or

       (iii)  confirmation  in  writing  by any Rating  Agency  that  failure to
              remove the  Special  Servicer  would,  in and of  itself,  cause a
              downgrade, qualification or withdrawal of the then current ratings
              assigned to any Class of Certificates; or

       (iv)   a decree or order of a court or agency  or  supervisory  authority
              having  jurisdiction in the premises in an involuntary  case under
              any present or future federal or state  bankruptcy,  insolvency or
              similar law for the  appointment  of a conservator  or receiver or
              liquidator in any insolvency,  readjustment of debt, marshaling of
              assets  and  liabilities  or  similar  proceedings,   or  for  the
              winding-up or liquidation of its affairs,  shall have been entered
              against the Special  Servicer  and such decree or order shall have
              remained  in force  undischarged  or  unstayed  for a period of 60
              days; or

       (v)    the  Special  Servicer  shall  consent  to  the  appointment  of a
              conservator   or  receiver  or  liquidator   in  any   insolvency,
              readjustment  of debt,  marshaling  of assets and  liabilities  or
              similar proceedings of or relating to the Special Servicer,  or of
              or relating to all or substantially all of its property; or

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

       (vii)  the  Special  Servicer  shall no longer be an  "approved"  special
              servicer by each of the Rating Agencies for mortgage pools similar
              to the Trust Fund;

then,  and in each and every such case, so long as a Special  Servicer  Event of
Default  shall not have been  remedied,  the  Trustee  may,  and at the  written
direction of the Holders of at least 25% of the  aggregate  Voting Rights of all
Certificates shall, terminate the Special Servicer.

     (c) In the event that the  Servicer or the Special  Servicer is  terminated
pursuant to this Section 7.01, the Trustee (the  "Terminating  Party") shall, by
notice in writing to the  Servicer or the Special  Servicer,  as the case may be
(the "Terminated Party"), terminate all of its rights and obligations under this
Agreement and in and to the Mortgage Loans and the proceeds thereof,  other than
any rights the Terminated  Party may have hereunder as a  Certificateholder  and
any rights or  obligations  that accrued  prior to the date of such  termination
(including  the right to receive all  amounts  accrued or owing to it under this
Agreement,  plus interest at the Advance Rate on such amounts until  received to
the extent such  amounts  bear  interest as  provided  in this  Agreement,  with
respect to periods  prior to the date of such  termination  and the right to the
benefits of Section 6.03 notwithstanding any such termination).  On or after the
receipt by the Terminated  Party, of such written  notice,  all of its authority
and power under this Agreement, whether with respect to the Certificates (except
that the Terminated Party shall retain its rights as a Certificateholder  in the
event and to the extent that it is a Certificateholder) or the Mortgage Loans or
otherwise,  shall pass to and be vested in the Terminating Party pursuant to and
under this Section and,  without  limitation,  the  Terminating  Party is hereby
authorized and empowered to execute and deliver, on behalf of and at the expense
of the Terminated Party, as attorney-in-fact or otherwise, any and all documents
and  other  instruments,  and to do or  accomplish  all  other  acts  or  things
necessary or appropriate  to effect the purposes of such notice of  termination,
whether to complete the transfer and  endorsement  or assignment of the Mortgage
Loans and related documents, or otherwise. The Servicer and the Special Servicer
each  agree in the  event it is  terminated  pursuant  to this  Section  7.01 to
promptly  (and in any event no later than ten Business  Days  subsequent to such
notice) provide,  at its own expense,  the Terminating  Party with all documents
and records  requested by the Terminating  Party to enable the Terminating Party
to assume its functions  hereunder,  and to cooperate with the Terminating Party
and the successor to its responsibilities hereunder in effecting the termination
of its responsibilities and rights hereunder, including, without limitation, the
transfer to the successor Servicer or Special Servicer or the Terminating Party,
as applicable,  for  administration by it of all cash amounts which shall at the
time be or should have been credited by the Servicer or the Special  Servicer to
the Collection Account, and any REO Account, Lock-Box Account or Cash Collateral
Account  thereafter  be received with respect to the Mortgage  Loans,  and shall
promptly provide the Terminating  Party or such successor  Servicer or successor
Special Servicer (which may include the Trustee),  as applicable,  all documents
and  records  reasonably  requested  by it,  such  documents  and  records to be
provided in such form as the  Terminating  Party or such  successor  Servicer or
Special Servicer shall reasonably request (including  electromagnetic  form), to
enable it to assume the Servicer's or Special Servicer's function hereunder. All
reasonable costs and expenses of the Terminating Party or the successor Servicer
or successor  Special  Servicer  incurred in connection  with  transferring  the
Mortgage Files to the successor  Servicer or Special  Servicer and amending this
Agreement to reflect such succession as successor  Servicer or successor Special
Servicer pursuant to this Section 7.01 shall be paid by the predecessor Servicer
or  the  Special  Servicer,  as  applicable,  upon  presentation  of  reasonable
documentation of such costs and expenses. If the predecessor Servicer or Special
Servicer (as the case may be) has not  reimbursed the  Terminating  Party or the
successor  Servicer or Special  Servicer for such expenses  within 90 days after
the presentation of reasonable  documentation,  such expense shall be reimbursed
by the Trust  Fund;  provided  that the  Terminated  Party  shall not thereby be
relieved  of its  liability  for such  expenses.  If and to the extent  that the
Terminated  Party has not reimbursed  such costs and expenses,  the  Terminating
Party shall have an  affirmative  obligation to take all  reasonable  actions to
collect such expenses on behalf of the Trust Fund.

     SECTION 7.02. Trustee to Act; Appointment of Successor.

     On and after the time the  Servicer  or the  Special  Servicer  receives  a
notice of termination  pursuant to Section 7.01, the Terminating  Party shall be
its  successor in all  respects in its capacity as Servicer or Special  Servicer
under this Agreement and the  transactions set forth or provided for herein and,
except as provided herein, shall be subject to all the responsibilities, duties,
limitations on liability and liabilities relating thereto and arising thereafter
placed on the Servicer or Special  Servicer by the terms and provisions  hereof;
provided,   however,   that   (i)   the   Terminating   Party   shall   have  no
responsibilities,  duties, liabilities or obligations with respect to any act or
omission of the Servicer or Special Servicer and (ii) any failure to perform, or
delay in performing,  such duties or  responsibilities  caused by the Terminated
Party's  failure to  provide,  or delay in  providing,  records,  tapes,  disks,
information  or monies  shall not be  considered  a  default  by such  successor
hereunder.  The Trustee,  as successor  Servicer or successor  Special Servicer,
shall be  indemnified  to the full  extent  provided  the  Servicer  or  Special
Servicer,  as applicable,  under this  Agreement  prior to the Servicer's or the
Special  Servicer's  termination.  The  appointment  of a successor  Servicer or
successor  Special  Servicer  shall not affect any liability of the  predecessor
Servicer or Special  Servicer which may have arisen prior to its  termination as
Servicer or Special Servicer.  The Terminating Party shall not be liable for any
of the representations and warranties of the Servicer or Special Servicer herein
or in any  related  document  or  agreement,  for any acts or  omissions  of the
predecessor  Servicer or predecessor Special Servicer or for any losses incurred
in respect of any Permitted  Investment by the Servicer pursuant to Section 3.07
hereunder  nor shall the  Trustee be  required to  purchase  any  Mortgage  Loan
hereunder. As compensation therefor, the Terminating Party as successor Servicer
or successor Special Servicer shall be entitled to the Servicing Compensation or
Special  Servicing  Compensation,  as applicable,  and all funds relating to the
Mortgage Loans that accrue after the date of the Terminating  Party's succession
to which the  Servicer  or  Special  Servicer  would have been  entitled  if the
Servicer or Special Servicer, as applicable,  had continued to act hereunder. In
the event any Advances  made by the Servicer and the Trustee or the Fiscal Agent
shall at any time be  outstanding,  or any amounts of interest  thereon shall be
accrued and  unpaid,  all  amounts  available  to repay  Advances  and  interest
hereunder  shall be applied  entirely to the Advances made by the Trustee or the
Fiscal Agent (and the accrued and unpaid interest thereon),  until such Advances
and  interest  shall have been repaid in full.  Notwithstanding  the above,  the
Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so
act, or if the Holders of Certificates entitled to at least 25% of the aggregate
Voting  Rights so request in writing to the  Trustee,  or if neither the Trustee
nor the Fiscal  Agent is rated by each  Rating  Agency in one of its two highest
long-term  debt  rating  categories  or if the Rating  Agencies  do not  provide
written  confirmation that the succession of the Trustee, as Servicer or Special
Servicer, as applicable, will not cause a downgrade, qualification or withdrawal
of the then current ratings assigned to the Certificates,  promptly appoint,  or
petition a court of competent  jurisdiction to appoint, any established mortgage
loan  servicing  institution  the  appointment  of which  will not  result  in a
downgrade,  qualification  or withdrawal  of the then current  rating or ratings
assigned to any Class of  Certificates  as  evidenced  in writing by each Rating
Agency,  as the successor to the Servicer or Special  Servicer,  as  applicable,
hereunder in the assumption of all or any part of the  responsibilities,  duties
or liabilities of the Servicer or Special Servicer hereunder.  No appointment of
a successor to the  Servicer or Special  Servicer  hereunder  shall be effective
until  the  assumption  by such  successor  of all  the  Servicer's  or  Special
Servicer's   responsibilities,   duties  and  liabilities   hereunder.   Pending
appointment  of a successor  to the  Servicer  (or the  Special  Servicer if the
Special  Servicer is also the Servicer)  hereunder,  unless the Trustee shall be
prohibited  by law from so acting,  the  Trustee  shall act in such  capacity as
herein above  provided.  Pending the  appointment  of a successor to the Special
Servicer,  unless the Servicer is also the Special Servicer,  the Servicer shall
act in such  capacity.  In  connection  with  such  appointment  and  assumption
described herein, 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  Terminated  Party  hereunder,  provided,  further,  that  if  no
successor to the Terminated  Party can be obtained to perform the obligations of
such Terminated Party hereunder for such compensation, then, subject to approval
by the Directing Holders, additional amounts shall be paid to such successor and
such amounts in excess of that permitted the  Terminated  Party shall be treated
as Realized  Losses.  Upon  determining that a successor to the Terminated Party
cannot be obtained for the compensation that the Terminated Party was receiving,
the Trustee  shall give notice of that fact to the Directing  Holders.  Once the
Trustee  has  determined  the amount of  compensation  acceptable  to a proposed
successor  to the  Terminated  Party,  the  Trustee  shall  give  notice  to the
Directing   Holders  of  the  identity  of  such   successor  and  the  proposed
compensation.  The  Directing  Holders will then have ten  Business  Days during
which to propose their own successor and compensation  (which must be acceptable
to the Rating  Agencies,  as evidenced in writing that the  appointment  of such
successor,  in and of itself would not result in a downgrade,  qualification  or
withdrawal  by any Rating  Agency of the then  current  ratings  assigned to the
Certificates)  or to approve  the  successor  and  compensation  proposed by the
Trustee.  The Depositor,  the Trustee, the Servicer or Special Servicer and such
successor shall take such action,  consistent  with this Agreement,  as shall be
necessary to effectuate any such succession.

     SECTION 7.03. Notification to Certificateholders.

     (a) Upon any termination pursuant to Section 7.01 above or appointment of a
successor to the Servicer or the Special Servicer, the Trustee shall give prompt
written  notice  thereof to  Certificateholders  at their  respective  addresses
appearing in the Certificate Register and to each Rating Agency.

     (b) Within 30 days after the  occurrence of any Event of Default of which a
Responsible  Officer of the Trustee  has actual  knowledge,  the  Trustee  shall
transmit by mail to all Holders of Certificates and to each Rating Agency notice
of such Event of Default,  unless such Event of Default shall have been cured or
waived.

     SECTION 7.04. Other Remedies of Trustee.

     During  the  continuance  of any  Servicer  Event of  Default  or a Special
Servicer Event of Default,  so long as such Servicer Event of Default or Special
Servicer  Event of Default,  if applicable,  shall not have been  remedied,  the
Trustee,  in addition to the rights  specified in Section  7.01,  shall have the
right,  in its own name as trustee of an express trust,  to take all actions now
or hereafter  existing at law, in equity or by statute to enforce its rights and
remedies and to protect the interests,  and enforce the rights and remedies,  of
the  Certificateholders  (including  the  institution  and  prosecution  of  all
judicial, administrative and other proceedings and the filing of proofs of claim
and debt in connection  therewith).  In such event, the legal fees, expenses and
costs of such action and any liability  resulting  therefrom  shall be expenses,
costs and liabilities of the Trust Fund, and the Trustee shall be entitled to be
reimbursed  therefor  from the  Collection  Account as provided in Section 3.06.
Except as otherwise expressly provided in this Agreement, no remedy provided for
by this  Agreement  shall be exclusive of any other  remedy,  and each and every
remedy shall be  cumulative  and in addition to any other remedy and no delay or
omission to exercise  any right or remedy  shall impair any such right or remedy
or shall be deemed to be a waiver of any  Servicer  Event of  Default or Special
Servicer Event of Default, if applicable.

     SECTION 7.05. Waiver of Past Events of Default; Termination.

     The  Holders  of  Certificates  evidencing  not less  than  66-2/3%  of the
aggregate  Voting  Rights of the  Certificates  may, on behalf of all Holders of
Certificates,  waive any  default by the  Servicer  or Special  Servicer  in the
performance of its obligations hereunder and its consequences,  except a default
in making any required deposits (including P&I Advances) to or payments from the
Collection  Account or the  Distribution  Account or in  remitting  payments  as
received,  in each case in accordance with this Agreement.  Upon any such waiver
of a past default,  such default shall cease to exist,  and any Event of Default
arising  therefrom  shall be deemed to have been  remedied for every  purpose of
this  Agreement.  No such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

     SECTION 8.01. Duties of Trustee.

     (a) The Trustee,  prior to the occurrence of an Event of Default of which a
Responsible  Officer of the Trustee has actual knowledge and after the curing or
waiver of all Events of Default which may have  occurred,  undertakes to perform
such duties and only such duties as are specifically set forth in this Agreement
and no permissive right of the Trustee shall be construed as a duty.  During the
continuance of an Event of Default of which a Responsible Officer of the Trustee
has actual  knowledge,  the Trustee,  subject to the provisions of Sections 7.02
and 7.05 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.

     (b) The Trustee, upon receipt of any resolutions, certificates, statements,
opinions,  reports,  documents,  orders or other  instruments  furnished  to the
Trustee  which  are  specifically  required  to be  furnished  pursuant  to  any
provision  of this  Agreement,  shall  examine  them to  determine  whether they
conform on their face to the requirements of this Agreement;  provided, however,
that,  the Trustee shall not be  responsible  for the accuracy or content of any
such resolution,  certificate,  statement,  opinion,  report, document, order or
other instrument  provided to it hereunder.  If any such instrument is found not
to  conform  on its face to the  requirements  of this  Agreement  in a material
manner,  the  Trustee  shall  take  action as it deems  appropriate  to have the
instrument  corrected,  and if the  instrument is not corrected to the Trustee's
reasonable  satisfaction,  the  Trustee  will  provide  notice  thereof  to  the
Certificateholders.

     (c)  Neither the Trustee  nor any of its  officers,  directors,  employees,
agents or  "control"  persons  within  the  meaning  of the Act  shall  have any
liability arising out of or in connection with this Agreement,  provided,  that,
subject to Section  8.02, no provision of this  Agreement  shall be construed to
relieve the Trustee,  or any such person,  from  liability for its own negligent
action,  its own negligent  failure to act or its own willful  misconduct or its
own bad faith; and provided, further, that:

       (i)    Prior  to the  occurrence  of an  Event  of  Default  of  which  a
              Responsible Officer of the Trustee has actual knowledge, and after
              the curing or waiver of all such Events of Default  which 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 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, in the absence of bad
              faith on the part of the  Trustee,  the Trustee  may  conclusively
              rely, as to the truth of the statements and the correctness of the
              opinions  expressed therein,  upon any resolutions,  certificates,
              statements,   reports,  opinions,   documents,   orders  or  other
              instruments furnished to the Trustee that conform on their face to
              the  requirements  of this Agreement  without  responsibility  for
              investigating the contents thereof;

       (ii)   The  Trustee  shall  not be  personally  liable  for an  error  of
              judgment  made  in  good  faith  by  a   Responsible   Officer  or
              Responsible  Officers,  unless it shall be proved that the Trustee
              was negligent in ascertaining the pertinent facts;

       (iii)  The Trustee  shall not be  personally  liable with  respect to any
              action taken,  suffered or omitted to be taken by it in good faith
              in  accordance  with the  direction  of  Holders  of  Certificates
              entitled to greater than 50% of the Percentage  Interests (or such
              other  percentage as is specified  herein) of each affected  Class
              (or the  Directing  Holders  if so  specified  herein),  or of the
              aggregate Voting Rights of the 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;

       (iv)   Neither the Trustee nor any of its respective directors, officers,
              employees,  agents or control persons shall be responsible for any
              act or  omission of any  Custodian,  Paying  Agent or  Certificate
              Registrar  that is not an  Affiliate  of the  Trustee  and that is
              selected  other  than by the  Trustee,  performed  or  omitted  in
              compliance  with any custodial or other  agreement,  or any act or
              omission of the Servicer,  Special Servicer,  the Depositor or any
              other Person,  including,  without limitation,  in connection with
              actions taken pursuant to this Agreement;

       (v)    The  Trustee  shall not be under  any  obligation  to  appear  in,
              prosecute or defend any legal action  which is not  incidental  to
              its respective duties as Trustee in accordance with this Agreement
              (and,  if it does,  all legal  expenses  and costs of such  action
              shall be expenses  and costs of the Trust  Fund),  and the Trustee
              shall be entitled to be reimbursed  therefor  from the  Collection
              Account,  unless such legal action arises out of the negligence or
              bad  faith  of  the  Trustee  or  any  breach  of  an  obligation,
              representation,  warranty or  covenant  of the  Trustee  contained
              herein; and

       (vi)   The  Trustee  shall  not be  charged  with  knowledge  of any act,
              failure  to act or breach of any  Person  upon the  occurrence  of
              which the Trustee may be  required  to act,  unless a  Responsible
              Officer of the Trustee  obtains actual  knowledge of such failure.
              The  Trustee  shall be  deemed  to have  actual  knowledge  of the
              Servicer's or the Special  Servicer's failure to provide scheduled
              reports,  certificates  and statements  when and as required to be
              delivered to the Trustee pursuant to this Agreement.

     None of the provisions contained in this Agreement shall require either the
Trustee,  in its capacity as Trustee, or the Fiscal Agent, to expend or risk its
own funds, or otherwise  incur financial  liability in the performance of any of
its duties  hereunder,  or in the exercise of any of its rights or powers, if in
the opinion of the Trustee or the Fiscal Agent,  respectively,  the repayment of
such  funds  or  adequate  indemnity  against  such  risk  or  liability  is not
reasonably assured to it, and none of the provisions contained in this Agreement
shall in any event  require the Trustee to perform,  or be  responsible  for the
manner of performance  of, any of the obligations of the Servicer or the Special
Servicer under this  Agreement,  except during such time, if any, as the Trustee
shall be the  successor  to, and be vested with the rights,  duties,  powers and
privileges of, the Servicer or the Special Servicer in accordance with the terms
of this Agreement. Neither the Trustee nor the Fiscal Agent shall be required to
post any surety or bond of any kind in connection  with its  performance  of its
obligations  under this  Agreement  and neither the Trustee nor the Fiscal Agent
shall  be  liable  for any loss on any  investment  of  funds  pursuant  to this
Agreement.

     SECTION 8.02. Certain Matters Affecting the Trustee.

     (a) Except as otherwise provided in Section 8.01:

       (i)    The Trustee may request and/or rely upon and shall be protected in
              acting or refraining  from acting upon any  resolution,  Officers'
              Certificate,  certificate  of auditors  or any other  certificate,
              statement,  instrument, opinion, report, notice, request, consent,
              order,  appraisal,  bond or  other  paper or  document  reasonably
              believed by it to be genuine and to have been signed or  presented
              by the  proper  party or  parties  and the  Trustee  shall have no
              responsibility to ascertain or confirm the genuineness of any such
              party or parties;

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

       (iii)  (A) The Trustee shall be under no obligation 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;  (B) the right of the
              Trustee  to  perform  any  discretionary  act  enumerated  in this
              Agreement  shall not be construed as a duty, and the Trustee shall
              not be  answerable  for  other  than  its  negligence  or  willful
              misconduct in the  performance  of any such act; and (C) provided,
              however,  that  subject  to  the  foregoing  clause  (A),  nothing
              contained  herein  shall  relieve the Trustee of the  obligations,
              upon the  occurrence  of an Event of  Default  (which has not been
              cured or waived) of which a Responsible Officer of the Trustee has
              actual knowledge, to exercise such of the rights and powers vested
              in it by this  Agreement,  and to use the same  degree of care and
              skill in their exercise, as a prudent person would exercise or use
              under  the  circumstances  in the  conduct  of such  person's  own
              affairs;

       (iv)   Neither the Trustee nor any of its directors, officers, employees,
              Affiliates,  agents or "control" persons within the meaning of the
              Act shall be personally  liable for any action taken,  suffered or
              omitted by it in good faith and reasonably believed by the Trustee
              to be  authorized  or within  the  discretion  or rights or powers
              conferred upon it by this Agreement;

       (v)    The Trustee shall not be bound to make any investigation  into the
              facts or matters stated in any resolution, certificate, statement,
              instrument,  opinion,  report, notice,  request,  consent,  order,
              approval,  bond or other paper or  document,  unless  requested in
              writing to do so by Holders of  Certificates  entitled to at least
              25% (or such  other  percentage  as is  specified  herein)  of the
              Percentage  Interests of any affected  Class;  provided,  however,
              that if the payment within a reasonable time to the Trustee of the
              costs,  expenses or liabilities likely to be incurred by it in the
              making of such  investigation  is, in the opinion of the  Trustee,
              not reasonably  assured to the Trustee by the security afforded to
              it by the  terms  of  this  Agreement,  the  Trustee  may  require
              reasonable  indemnity  against  such  expense  or  liability  as a
              condition to taking any such  action.  The  reasonable  expense of
              every  such  investigation  shall be paid by the  Servicer  or the
              Special Servicer if an Event of Default shall have occurred and be
              continuing  relating to the  Servicer,  or the  Special  Servicer,
              respectively,  and otherwise by the Certificateholders  requesting
              the investigation; and

       (vi)   The Trustee may execute any of the trusts or powers  hereunder  or
              perform  any duties  hereunder  either  directly  or by or through
              agents or attorneys  but shall not be relieved of the  obligations
              hereunder.

     (b) Following the Start-up Day, the Trustee shall not,  except as expressly
required by any provision of this Agreement,  accept any  contribution of assets
to the Trust Fund unless the Trustee  shall have  received an Opinion of Counsel
(the costs of obtaining such opinion to be borne by the Person  requesting  such
contribution)  to the effect that the inclusion of such assets in the Trust Fund
will not cause either the Upper-Tier  REMIC or the  Lower-Tier  REMIC to fail to
qualify as a REMIC at any time that any  Certificates are outstanding or subject
either the Upper-Tier  REMIC or the Lower-Tier  REMIC to any tax under the REMIC
Provisions or other  applicable  provisions  of federal,  state and local law or
ordinances.

     (c)  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.

     The Trustee shall have no duty to conduct any affirmative  investigation as
to the occurrence of any condition requiring the repurchase of any Mortgage Loan
by the Depositor  pursuant to this Agreement or the  eligibility of any Mortgage
Loan for purposes of this Agreement.

     SECTION  8.03.  Trustee  and Fiscal  Agent Not Liable for  Certificates  or
                     Mortgage Loans.

     The recitals contained herein and in the Certificates shall not be taken as
the statements of the Trustee,  the Fiscal Agent,  the Servicer,  or the Special
Servicer  and the  Trustee,  the Fiscal  Agent,  the  Servicer  and the  Special
Servicer assume no responsibility for their correctness. The Trustee, the Fiscal
Agent,  the  Servicer  and  the  Special  Servicer  make no  representations  or
warranties  as to  the  validity  or  sufficiency  of  this  Agreement,  of  the
Certificates  or any prospectus used to offer the  Certificates  for sale or the
validity,  enforceability  or  sufficiency  of any  Mortgage  Loan,  or  related
document.  Neither the  Trustee nor the Fiscal  Agent shall at any time have any
responsibility  or liability for or with respect to the  legality,  validity and
enforceability  of any  Mortgage,  any  Mortgage  Loan,  or the  perfection  and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with  respect to the  sufficiency  of the Trust Fund or its ability to
generate  the  payments  to be  distributed  to  Certificateholders  under  this
Agreement.  Without  limiting the foregoing,  neither the Trustee nor the Fiscal
Agent shall be liable or responsible for: the existence, condition and ownership
of any  Mortgaged  Property;  the  existence  of any  hazard or other  insurance
thereon  (other than if the Trustee  shall  assume the duties of the Servicer or
the Special Servicer  pursuant to Section 7.02) or the  enforceability  thereof;
the existence of any Mortgage Loan or the contents of the related  Mortgage File
on any computer or other record  thereof (other than if the Trustee shall assume
the duties of the Servicer or the Special  Servicer  pursuant to Section  7.02);
the validity of the  assignment of any Mortgage Loan to the Trust Fund or of any
intervening  assignment;  the completeness of any Mortgage File; the performance
or  enforcement of any Mortgage Loan (other than if the Trustee shall assume the
duties of the Servicer or the Special  Servicer  pursuant to Section 7.02);  the
compliance  by the  Depositor,  the  Servicer or the Special  Servicer  with any
warranty or representation  made under this Agreement or in any related document
or the accuracy of any such  warranty or  representation  prior to the Trustee's
receipt of notice or other  discovery  of any  non-compliance  therewith  or any
breach thereof;  any investment of monies by or at the direction of the Servicer
or any loss  resulting  therefrom,  it being  understood  that the Trustee shall
remain  responsible  for  any  Trust  Fund  property  that  it may  hold  in its
individual capacity; the acts or omissions of any of the Depositor, the Servicer
or the Special  Servicer  (other than if the Trustee  shall assume the duties of
the Servicer or Special Servicer pursuant to Section 7.02) or any subservicer or
any Borrower;  any action of the Servicer or Special Servicer (other than if the
Trustee shall assume the duties of the Servicer or Special Servicer  pursuant to
Section 7.02) or any subservicer taken in the name of the Trustee, except to the
extent such action is taken at the express written direction of the Trustee; the
failure of the  Servicer or the Special  Servicer or any  subservicer  to act or
perform  any duties  required  of it on behalf of the Trust Fund or the  Trustee
hereunder;  or any action by or omission of the Trustee taken at the instruction
of the Servicer or the Special  Servicer (other than if the Trustee shall assume
the duties of the  Servicer or the Special  Servicer  pursuant to Section  7.02)
unless the taking of such action is not  permitted by the express  terms of this
Agreement;  provided,  however, that the foregoing shall not relieve the Trustee
of its  obligation  to  perform  its  duties as  specifically  set forth in this
Agreement. Neither the Trustee nor the Fiscal Agent shall be accountable for the
use or application by the Depositor, the Servicer or the Special Servicer of any
of the Certificates or of the proceeds of such  Certificates,  or for the use or
application  of any funds paid to the  Depositor,  the  Servicer  or the Special
Servicer in respect of the  assignment of the Mortgage  Loans or deposited in or
withdrawn  from  the  Collection  Account,   Distribution  Account,   Upper-Tier
Distribution  Account,   Lock-Box  Account,  Cash  Collateral  Account,  Reserve
Accounts,  Interest Reserve Account,  Default Interest  Distribution  Account or
Excess Interest  Distribution  Account or any other account  maintained by or on
behalf of the Servicer or the Special Servicer, other than any funds held by the
Trustee or the Fiscal Agent,  as applicable.  Neither the Trustee nor the Fiscal
Agent shall have any  responsibility  for filing any  financing or  continuation
statement in any public  office at any time or to otherwise  perfect or maintain
the perfection of any security  interest or lien granted to it hereunder (unless
the  Trustee  shall  have  become  the  successor  Servicer)  or to record  this
Agreement.  In making any  calculation  hereunder  which includes as a component
thereof the payment or  distribution of interest for a stated period at a stated
rate "to the extent  permitted by applicable law," the Trustee shall assume that
such payment is so  permitted  unless a  Responsible  Officer of the Trustee has
actual  knowledge,  or  receives  an Opinion of Counsel  (at the  expense of the
Person asserting the  impermissibility)  to the effect, that such payment is not
permitted by applicable law.

     SECTION 8.04. Trustee and Fiscal Agent May Own Certificates.

     The Trustee, the Fiscal Agent and any agent of the Trustee and Fiscal Agent
in its individual capacity or any other capacity may become the owner or pledgee
of  Certificates,  and may deal with the  Depositor  and the Servicer in banking
transactions,  with the same rights it would have if it were not Trustee, Fiscal
Agent or such agent.

     SECTION 8.05. Payment of Trustee's Fees and Expenses; Indemnification.

     (a) The  Trustee  or any  successor  Trustee  shall  be  entitled,  on each
Distribution  Date,  to the  Trustee  Fee  (which  shall not be  limited  by any
provision of law in regard to the compensation of a trustee of an express trust)
for all services  rendered by the Trustee in the  execution of the trusts hereby
created  and in the  exercise  and  performance  of any of the powers and duties
hereunder of the Trustee,  which  Trustee Fee shall be paid to the Trustee prior
to  the   distribution   on   such   Distribution   Date  of   amounts   to  the
Certificateholders.  In  the  event  that  the  Trustee  assumes  the  servicing
responsibilities  of the Servicer or the Special Servicer  hereunder pursuant to
or  otherwise  arising  from the  resignation  or removal of the Servicer or the
Special Servicer, the Trustee shall be entitled to the compensation to which the
Servicer or the Special Servicer, as the case may be, would have been entitled.

     (b) The Trustee and the Fiscal  Agent shall each be paid or  reimbursed  by
the Trust Fund upon its request for all reasonable  expenses,  disbursements and
advances  incurred or made by the Trustee or the Fiscal Agent pursuant to and in
accordance  with  any  of  the  provisions  of  this  Agreement  (including  the
reasonable compensation and the expenses and disbursements of its counsel and of
all  persons  not  regularly  in its  employ) to the extent  such  payments  are
"unanticipated  expenses  incurred by the REMIC"  within the meaning of Treasury
Regulations Section  1.860G-1(b)(iii)  except any such expense,  disbursement or
advance as may arise from its negligence or bad faith; provided,  however, that,
subject to the last  paragraph  of Section  8.01,  neither  the  Trustee nor the
Fiscal  Agent shall  refuse to perform any of its duties  hereunder  solely as a
result of the failure to be paid the Trustee Fee and the  Trustee's  expenses or
any sums due to the Fiscal Agent.

     The  Servicer  and  the  Special  Servicer  covenant  and  agree  to pay or
reimburse the Trustee for the reasonable  expenses,  disbursements  and advances
incurred or made by the Trustee in connection with any transfer of the servicing
responsibilities  of  the  Servicer  or  the  Special  Servicer,   respectively,
hereunder,  pursuant to or otherwise  arising from the resignation or removal of
the Servicer,  in accordance  with any of the  provisions of this Agreement (and
including the reasonable fees and expenses and  disbursements of its counsel and
all other  persons  not  regularly  in its  employ),  except  any such  expense,
disbursement  or advance as may arise  from the  negligence  or bad faith of the
Trustee or  expenses  incurred  by the  Trustee  in its  capacity  as  successor
Servicer;  provided,  that in the event that the Servicer is terminated pursuant
to Section 6.04(c),  expenses incurred in connection with such transfer shall be
paid by the Depositor.

     (c) Each of the Paying Agent, the Certificate Registrar, the Custodian, the
Depositor,  the  Servicer,  the  Special  Servicer  and  the  Trustee  (each,  a
"Cross-Indemnifying  Party") shall indemnify the Servicer, the Special Servicer,
the Trustee and the Fiscal Agent and their respective Affiliates and each of the
directors,  officers,  employees and agents of the Trustee, the Fiscal Agent and
their respective  Affiliates (each, a "Cross-Indemnified  Party"), and hold each
of them harmless against any and all claims, losses, damages,  penalties, fines,
forfeitures,  reasonable and necessary legal fees and related costs,  judgments,
and any other costs,  fees and  expenses  that the  Cross-Indemnified  Party may
sustain  in  connection  with this  Agreement  (including,  without  limitation,
reasonable fees and  disbursements of counsel incurred by the  Cross-Indemnified
Party in any action or proceeding between the  Cross-Indemnifying  Party and the
Cross-Indemnified  Party or between  the  Cross-Indemnified  Party and any third
party or otherwise) related to each such  Cross-Indemnifying  Party's respective
willful  misconduct,  bad faith,  fraud and/or  negligence in the performance of
each of its respective  duties  hereunder or by reason of reckless  disregard of
its respective  obligations and duties  hereunder  (including in the case of the
Servicer, any agent of the Servicer or subservicer).

     (d) The Trust Fund shall  indemnify  the Trustee  and the Fiscal  Agent and
their respective Affiliates and each of the directors,  officers,  employees and
agents of the Trustee, the Fiscal Agent and their respective Affiliates (each, a
"Trust-Indemnified  Party")  from,  and hold it  harmless  against,  any and all
losses,  liabilities,  damages,  claims or  unanticipated  expenses  (including,
without limitation, reasonable fees and disbursements of counsel incurred by the
Trust-Indemnified  Party in any action or  proceeding  between any of the Paying
Agent, the Certificate Registrar, the Custodian, the Depositor, the Servicer and
the  Special   Servicer   and  the   Trust-Indemnified   Party  or  between  the
Trust-Indemnified  Party and any third party or otherwise) arising in respect of
this Agreement or the  Certificates,  in each case to the extent and only to the
extent,  such payments are expressly  reimbursable  under this  Agreement or are
"unanticipated  expenses  incurred by the REMIC"  within the meaning of Treasury
Regulations Section 1.860G-1(b)(3)(iii), other than (i) those resulting from the
negligence,  fraud,  bad faith or willful  misconduct  of the  Trust-Indemnified
Party and (ii) those as to which such  Trust-Indemnified  Party is  entitled  to
indemnification  pursuant to Section 8.05(c).  The term "unanticipated  expenses
incurred by a REMIC" shall include any fees,  expenses and  disbursement  of any
separate  trustee or  co-trustee  appointed  hereunder,  only to the extent such
fees,  expenses and  disbursements  were not  reasonably  anticipated  as of the
Closing Date and the losses, liabilities, damages, claims or expenses (including
reasonable attorneys' fees) incurred or advanced by a Trust-Indemnified Party in
connection with any litigation arising out of this Agreement, including, without
limitation,  under Section 2.03,  Section 3.10,  the third  paragraph of Section
3.11,  Section  4.05  and  Section  7.01.  The  right  of  reimbursement  of the
Trust-Indemnified  Parties  under this  Section  8.05(d)  shall be senior to the
rights of all Certificateholders.

     (e)  Notwithstanding  anything  herein to the  contrary,  this Section 8.05
shall survive the  termination or maturity of this Agreement or the  resignation
or removal of the  Trustee or the Fiscal  Agent,  as the case may be, as regards
rights  accrued  prior to such  resignation  or removal and (with respect to any
acts or omissions during their respective  tenures) the resignation,  removal or
termination  of the  Servicer,  the  Special  Servicer,  the Paying  Agent,  the
Certificate Registrar or the Custodian.

     (f) This Section 8.05 shall be expressly  construed to include,  but not be
limited to, such indemnities,  compensation, expenses, disbursements,  advances,
losses,  liabilities,  damages  and the like,  as may  pertain  or relate to any
environmental law or environmental matter.

     SECTION 8.06. Eligibility Requirements for Trustee.

     The Trustee  hereunder  shall at all times be a corporation  or association
organized and doing business under the laws of any state or the United States of
America,  authorized  under such laws to exercise  corporate trust powers and to
accept the trust conferred under this Agreement,  having a combined  capital and
surplus of at least $50,000,000 and a rating on its unsecured  long-term debt of
at least "BBB" by Fitch,  DCR and S&P and "Baa2" by Moody's (or at any time when
there is no Fiscal Agent appointed and acting hereunder or any such Fiscal Agent
so appointed  has a rating on its  long-term  unsecured  debt that is lower than
"AA" by Fitch,  DCR and S&P and "Aa2" by Moody's  (without regard to any plus or
minus or numeric  qualifier)  the rating on the unsecured  long term debt of the
Trustee  must be at least "AA" by Fitch,  DCR and S&P and "Aa2" by  Moody's,  or
meet different  standards  provided that each Rating Agency shall have confirmed
in writing that such different standards would not, in and of itself,  result in
a downgrade, qualification or withdrawal of the then current ratings assigned to
the  Certificates) and subject to supervision or examination by federal or state
authority  and shall not be an  Affiliate  of the  Servicer  (except  during any
period  when the Trustee  has  assumed  the duties of the  Servicer  pursuant to
Section 7.02); provided that,  notwithstanding that the long-term unsecured debt
of LaSalle National Bank and ABN AMRO Bank N.V. are not rated by Fitch,  LaSalle
National Bank shall not fail to qualify as Trustee  solely by virtue of the lack
of such ratings until such time as Fitch shall notify the Trustee,  the Servicer
and the Special  Servicer in writing  that  LaSalle  National  Bank is no longer
exempt from the foregoing  rating  requirements  imposed by this sentence.  If a
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 purposes of this Section the combined capital and surplus of
such  corporation  shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published. In the event that the
place of business from which the Trustee  administers  the Trust Fund is a state
or local  jurisdiction that imposes a tax on the Trust Fund or the net income of
a REMIC  (other  than a tax  corresponding  to a tax  imposed  under  the  REMIC
Provisions)  the Trustee  shall elect  either to (i) resign  immediately  in the
manner and with the effect  specified  in  Section  8.07,  (ii) pay such tax and
continue  as Trustee or (iii)  administer  the Trust Fund from a state and local
jurisdiction  that does not impose  such a tax.  In case at any time the Trustee
shall cease to be eligible in  accordance  with the  provisions of this Section,
the Trustee shall resign immediately in the manner and with the effect specified
in Section 8.07.

     SECTION 8.07. Resignation and Removal of the Trustee.

     The Trustee may at any time resign and be discharged from the trusts hereby
created by giving written notice  thereof to the  Depositor,  the Servicer,  the
Special  Servicer and each Rating Agency.  Upon such notice of resignation,  the
Fiscal  Agent shall also be deemed to have been removed  and,  accordingly,  the
Servicer shall promptly  appoint a successor  Trustee,  the appointment of which
would not, as  evidenced  in writing,  in and of itself,  result in a downgrade,
qualification  or withdrawal  by any Rating  Agency of the then current  ratings
assigned to the  Certificates,  and a successor  Fiscal  Agent (if  necessary to
satisfy the  requirements  contained in Section 8.06), the appointment of which,
if the  successor  Trustee is not rated by each Rating  Agency in one of its two
highest long-term debt rating categories, would not, as evidenced in writing, in
and of itself, result in a downgrade,  qualification or withdrawal by any Rating
Agency of the then  current  ratings  assigned to the  Certificates,  by written
instrument, in triplicate,  which instrument shall be delivered to the resigning
Trustee,  with a copy to the Fiscal  Agent  deemed  removed,  and the  successor
Trustee and successor Fiscal Agent. If no successor Trustee and successor Fiscal
Agent shall have been so appointed and have accepted  appointment within 30 days
after the giving of such notice of  resignation,  the resigning  Trustee and the
Fiscal  Agent  may  petition  any  court  of  competent   jurisdiction  for  the
appointment of a successor Trustee and successor Fiscal Agent.

     If at any time the Trustee  shall cease to be eligible in  accordance  with
the  provisions of Section 8.06 and shall fail to resign after  written  request
therefor by the  Depositor  or  Servicer,  or if at any time the  Trustee  shall
become  incapable of acting,  or shall be adjudged  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 upon
a confirmation in writing by any Rating Agency that not terminating the Trustee,
or  the  Fiscal  Agent,  as  applicable,  would,  in and of  itself,  cause  the
then-current  rating  assigned  to any Class of  Certificates  to be  qualified,
withdrawn or  downgraded,  then the  Depositor or the Servicer  shall remove the
Trustee and the Fiscal Agent and the Servicer shall promptly appoint a successor
Trustee  and  successor  Fiscal  Agent by  written  instrument,  which  shall be
delivered  to the Trustee and the Fiscal  Agent so removed and to the  successor
Trustee and the successor Fiscal Agent.

     The Holders of  Certificates  entitled to at least 50% of the Voting Rights
may at any time remove the Trustee and the Fiscal  Agent (and any removal of the
Trustee  shall be deemed to be a removal also of the Fiscal Agent) and appoint a
successor   Trustee  and  successor  Fiscal  Agent  by  written   instrument  or
instruments,   in   seven   originals,   signed   by  such   Holders   or  their
attorneys-in-fact  duly authorized,  one complete set of which instruments shall
be delivered to the  Depositor,  one complete set to the Servicer,  one complete
set to the Trustee so  removed,  one  complete  set to the Fiscal  Agent  deemed
removed, one complete set to the successor Trustee so appointed and one complete
set to the successor Fiscal Agent so appointed.

     In the event of removal of the Trustee, the Fiscal Agent shall be deemed to
have been removed.

     In the event that the  Trustee  or Fiscal  Agent is  terminated  or removed
pursuant to this  Section  8.07,  all of its rights and  obligations  under this
Agreement and in and to the Mortgage Loans shall be  terminated,  other than any
rights or  obligations  that accrued  prior to the date of such  termination  or
removal  (including  the right to receive all fees,  expenses and other  amounts
accrued or owing to it under this  Agreement,  plus interest at the Advance Rate
on all such amounts  until  received to the extent such amounts bear interest as
provided in this  Agreement,  with respect to periods  prior to the date of such
termination or removal).

     Any  resignation or removal of the Trustee and Fiscal Agent and appointment
of a successor  Trustee and, if such trustee is not rated by each Rating  Agency
in one of its two highest long-term debt rating  categories,  a successor Fiscal
Agent  pursuant to any of the  provisions  of this Section 8.07 shall not become
effective  until  acceptance of  appointment  by the  successor  Trustee and, if
necessary, successor Fiscal Agent as provided in Section 8.08.

     SECTION 8.08. Successor Trustee and Fiscal Agent.

     (a) Any  successor  Trustee and any  successor  Fiscal  Agent  appointed as
provided  in  Section  8.07  shall  execute,  acknowledge  and  deliver  to  the
Depositor, to the Servicer and to the predecessor Trustee and predecessor Fiscal
Agent, as the case may be,  instruments  accepting their appointment  hereunder,
and  thereupon  the  resignation  or  removal  of the  predecessor  Trustee  and
predecessor  Fiscal Agent shall become effective and such successor  Trustee and
successor  Fiscal  Agent,  without any further act,  deed or  conveyance,  shall
become fully vested with all the rights,  powers,  duties and obligations of its
predecessor hereunder, with the like effect as if originally named as Trustee or
Fiscal Agent herein, provided that the appointment of such successor Trustee and
successor  Fiscal  Agent  shall  not,  as  evidenced  in  writing,  result  in a
downgrade,  qualification  or withdrawal of the then current ratings assigned to
the Certificates. The predecessor Trustee shall deliver to the successor Trustee
all Mortgage Files and related  documents and  statements  held by it hereunder,
and the  Depositor  and the  predecessor  Trustee 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  shall accept
appointment  as  provided  in  this  Section  8.08  unless  at the  time of such
acceptance  such  successor  Trustee shall be eligible  under the  provisions of
Section 8.06.

     Upon  acceptance of appointment by a successor  Trustee as provided in this
Section 8.08, the Depositor  shall mail notice of the succession of such Trustee
hereunder  to all Holders of  Certificates  at their  addresses  as shown in the
Certificate  Register. If the Depositor fails to mail such notice within 10 days
after acceptance of appointment by the successor Trustee,  the successor Trustee
shall cause such notice to be mailed at the expense of the Depositor.

     (b) Any  successor  Trustee  or Fiscal  Agent  appointed  pursuant  to this
Agreement shall satisfy the eligibility  requirements  set forth in Section 8.06
hereof.

     SECTION 8.09. Merger or Consolidation of Trustee.

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

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

     Notwithstanding  any other provisions  hereof, at any time, for the purpose
of meeting any legal  requirements of any  jurisdiction in which any part of the
Trust  Fund or  property  securing  the  same may at the  time be  located,  the
Depositor 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 (at the expense of the  Trustee) as  co-trustee  or  co-trustees,
jointly with the Trustee,  or separate trustee or separate  trustees,  of all or
any part of the  Trust  Fund,  and to vest in such  Person or  Persons,  in such
capacity, such title to the Trust Fund, or any part thereof, and, subject to the
other provisions of this Section 8.10, such powers, duties, obligations,  rights
and trusts as the Depositor and the Trustee may consider necessary or desirable.
If the Depositor shall not have joined in such appointment  within 15 days after
the  receipt by it of a request  so to do, or in case an Event of Default  shall
have occurred and be continuing,  the Trustee alone shall have the power to make
such  appointment.  Except as required by applicable  law, the  appointment of a
co-trustee   or  separate   trustee   shall  not  relieve  the  Trustee  of  its
responsibilities,  obligations  and  liabilities  hereunder.  No  co-trustee  or
separate trustee hereunder shall be required to meet the terms of eligibility as
a successor  Trustee  under  Section 8.06  hereunder and no notice to Holders of
Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be
required under Section 8.08 hereof.

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

     No trustee under this Agreement shall be personally liable by reason of any
act or omission of any other trustee under this Agreement. The Depositor and the
Trustee acting  jointly may at any time accept the  resignation of or remove any
separate  trustee or co-trustee,  or if the separate trustee or co-trustee is an
employee of the Trustee,  the Trustee acting alone may 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  VIII.  Every such  instrument  shall be filed with the Trustee.
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.  In no
event shall any such separate trustee or co-trustee be entitled to any provision
relating to the conduct of affecting the liability of or affording protection to
such  separate  trustee or  co-trustee  that  imposes a standard of conduct less
stringent  than  that  imposed  by  the  Trustee  hereunder,  affording  greater
protection  than that  afforded to the Trustee  hereunder or providing a greater
limit on liability than that provided to the Trustee hereunder.

     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.

     SECTION 8.11.  Fiscal Agent Appointed; Concerning the Fiscal Agent.

     (a) The Trustee  hereby  appoints ABN AMRO Bank N.V. as the initial  Fiscal
Agent  hereunder for the purposes of exercising and  performing the  obligations
and duties imposed upon the Fiscal Agent by Sections 3.24 and 4.06.

     (b) The Fiscal Agent undertakes to perform such duties and only such duties
as are specifically set forth in Sections 3.24 and 4.06.

     (c) No provision of this Agreement shall be construed to relieve the Fiscal
Agent from  liability  for its own  negligent  failure to act or its own willful
misfeasance or for a breach of a representation  or warranty  contained  herein;
provided, however, that (i) the duties and obligations of the Fiscal Agent shall
be determined  solely by the express  provisions of Sections 3.24 and 4.06,  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,
the Special  Servicer  or the Trustee and which on their face do not  contradict
the  requirements of this  Agreement,  and (ii) the provisions of clause (ii) of
Section 8.01(c) shall apply to the Fiscal Agent.

     (d) Except as otherwise provided in Section 8.11(c),  the Fiscal Agent also
shall have the benefit of provisions of clauses (i), (ii), (iii) (other than the
proviso thereto), (iv), (v) (other than the proviso thereto) and (vi) of Section
8.02(a).

                                   ARTICLE IX

                                   TERMINATION

     SECTION 9.01. Termination.

     (a) The respective  obligations and  responsibilities of the Servicer,  the
Special Servicer, the Depositor, the Trustee and the Fiscal Agent created hereby
with  respect to the  Certificates  (other than the  obligation  to make certain
payments and to send certain  notices to  Certificateholders  as hereinafter set
forth) shall terminate  immediately  following the occurrence of the last action
required  to be  taken  by  the  Trustee  pursuant  to  this  Article  IX on the
Termination Date;  provided,  however,  that in no event shall the trust created
hereby continue beyond the expiration of twenty-one  years from the death of the
last survivor of the  descendants of Joseph P. Kennedy,  the late  Ambassador of
the United States to the United Kingdom, living on the date hereof.

     (b) The Trust Fund, the Upper-Tier  REMIC and the Lower-Tier REMIC shall be
terminated and the assets of the Trust Fund shall be sold or otherwise  disposed
of in connection  therewith,  only pursuant to a "plan of complete  liquidation"
within the  meaning of Code  Section  860F(a)(4)(A)  providing  for the  actions
contemplated by the provisions hereof pursuant to which the applicable Notice of
Termination is given and requiring that the Trust Fund, the Upper-Tier REMIC and
the Lower-Tier  REMIC shall terminate on a Distribution  Date occurring not more
than 90 days following the date of adoption of the plan of complete liquidation.
For purposes of this Section 9.01(b),  the Notice of Termination  given pursuant
to  Section  9.01(c)  shall  constitute  the  adoption  of the plan of  complete
liquidation  as of the date such notice is given,  which date shall be specified
by the Servicer in the final federal income tax returns of the Upper-Tier  REMIC
and the Lower-Tier REMIC. Notwithstanding the termination of the Trust REMICs or
the Trust  Fund,  the  Trustee  shall be  responsible  for  filing the final Tax
Returns for the Trust REMICs and applicable  income tax or  information  returns
for the Grantor  Trust for the period  ending with such  termination,  and shall
retain books and records with respect to the Trust REMICs and the Grantor  Trust
for the same period of retention  for which it maintains  its own tax returns or
other reasonable period.

     (c) The Depositor,  and if the Depositor does not exercise the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  specifying  the  Anticipated   Termination  Date,  by
purchasing  on such date all, but not less than all, of the Mortgage  Loans then
included in the Trust Fund, and all property acquired in respect of any Mortgage
Loan, at a purchase price,  payable in cash,  equal to not less than the greater
of:

       (i)    the sum of

          (A)  100%  of the  unpaid  principal  balance  of each  Mortgage  Loan
               included  in the  Trust  Fund  as of the  last  day of the  month
               preceding   such   Distribution   Date  (less  any  P&I  Advances
               previously made on account of principal);

          (B)  the fair market value of all other property included in the Trust
               Fund as of the last day of the month preceding such  Distribution
               Date, as determined by an Independent appraiser acceptable to the
               Servicer  as of the date not more than 30 days  prior to the last
               day of the month preceding such Distribution Date;

          (C)  all unpaid  interest  accrued on such  principal  balance of each
               such Mortgage Loan  (including for this purpose any Mortgage Loan
               as to which  title to the  related  Mortgaged  Property  has been
               acquired)  at the  Mortgage  Rate (plus the Excess  Rate,  to the
               extent  applicable),  to the last day of the month preceding such
               Distribution  Date  (less  any P&I  Advances  previously  made on
               account of interest);

          (D)  the  aggregate  amount of  unreimbursed  Advances,  with interest
               thereon at the Advance Rate, and unpaid  Servicing  Compensation,
               Special  Servicing  Compensation,  Trustee  Fees and  Trust  Fund
               expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and expenses incurred by any and all parties to this Agreement or
by the Trust Fund in  connection  with the  purchase of the  Mortgage  Loans and
other assets of the Trust Fund  pursuant to this Section  9.01(c) shall be borne
by the party  exercising  its purchase  rights  hereunder.  The Trustee shall be
entitled  to rely  conclusively  on any  determination  made  by an  Independent
appraiser pursuant to this subsection (c).

     Anything in this Section 9.01 to the contrary notwithstanding,  the holders
of the Class V-1  Certificates  shall  receive that portion of the proceeds of a
sale of the assets of the Trust Fund allocable to the Net Default  Interest,  as
their interests may appear,  and the holders of the Class V-2 Certificates shall
receive  that  portion of the proceeds of a sale of the assets of the Trust Fund
allocable to Excess Interest, as their interests may appear.

     (d) If the  Trust  Fund  has not been  previously  terminated  pursuant  to
subsection  (c) of this Section  9.01,  the Trustee  shall  determine as soon as
practicable the Distribution Date on which the Trustee  reasonably  anticipates,
based on information with respect to the Mortgage Loans  previously  provided to
it, that the final  distribution  will be made (i) to the Holders of outstanding
Regular  Certificates,  and to the Trustee in respect of the Lower-Tier  Regular
Interests   notwithstanding  that  such  distribution  may  be  insufficient  to
distribute in full the  Certificate  Balance of each  Certificate  or Lower-Tier
Regular  Interest,  together  with amounts  required to be  distributed  on such
Distribution  Date  pursuant to Section  4.01(a),  (b), (c) or (d) or (ii) if no
such Classes of Certificates are then  outstanding,  to the Holders of the Class
LR  Certificates  of any  amount  remaining  in the  Collection  Account  or the
Distribution  Account  and to the  Holders  of the Class R  Certificates  of any
amount  remaining  in the  Upper-Tier  Distribution  Account,  in  either  case,
following  the  later to  occur of (A) the  receipt  or  collection  of the last
payment  due on  any  Mortgage  Loan  included  in the  Trust  Fund  or (B)  the
liquidation  or  disposition  pursuant to Section 3.18 of the last asset held by
the Trust Fund.

     (e) Notice of any  termination  of the Trust Fund  pursuant to this Section
9.01 shall be mailed by the Trustee to affected  Certificateholders  with a copy
to the  Servicer  and  each  Rating  Agency  at  their  addresses  shown  in the
Certificate  Registrar  as soon as  practicable  after the  Trustee  shall  have
received,  given or been deemed to have received a Notice of Termination  but in
any event not more than thirty  days,  and not less than ten days,  prior to the
Anticipated  Termination  Date.  The notice  mailed by the  Trustee to  affected
Certificateholders shall:

       (i)    specify  the  Anticipated  Termination  Date on  which  the  final
              distribution  is anticipated to be made to Holders of Certificates
              of the Classes specified therein;

       (ii)   specify the amount of any such final distribution, if known; and

       (iii)  state that the final  distribution to  Certificateholders  will be
              made only upon  presentation  and surrender of Certificates at the
              office of the Paying Agent therein specified.

If the Trust Fund is not terminated on any Anticipated  Termination Date for any
reason,  the  Trustee  shall  promptly  mail  notice  thereof  to each  affected
Certificateholder.

     (f) Any  funds not  distributed  on the  Termination  Date  because  of the
failure of any  Certificateholders  to tender  their  Certificates  shall be set
aside  and  held in  trust  for the  account  of the  appropriate  non-tendering
Certificateholders,   whereupon   the  Trust  Fund  shall   terminate.   If  any
Certificates as to which notice of the Termination  Date has been given pursuant
to this Section 9.01 shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee  hereunder and the transfer of such amounts to
a successor  Trustee and (ii) the termination of the Trust Fund and distribution
of such amounts to the Class R  Certificateholders.  No interest shall accrue or
be  payable  to any  Certificateholder  on any  amount  held as a result of such
Certificateholder's  failure to surrender its  Certificate(s)  for final payment
thereof in accordance  with this Section 9.01.  Any such amounts  transferred to
the Trustee may be invested  in  Permitted  Investments  and all income and gain
realized from investment of such funds shall be for the benefit of the Trustee.

     (g) The Holder of a 100%  Percentage  Interest in the Class LR Certificates
may purchase any Mortgage Loan on its  Anticipated  Repayment Date, if any, at a
price equal to the sum of the following:

       (i)    100% of the outstanding principal balance of such Mortgage Loan on
              such Anticipated  Repayment Date (less any P&I Advances previously
              made on account of principal);

       (ii)   all  unpaid  interest  accrued on such  principal  balance of such
              Mortgage Loan at the Mortgage Rate thereof, to the last day of the
              Interest Accrual Period preceding such Anticipated  Repayment Date
              (less any P&I Advances previously made on account of interest);

       (iii)  the aggregate amount of all unreimbursed  Advances with respect to
              such Mortgage Loan, with interest thereon at the Advance Rate, and
              unpaid Special  Servicing  Compensation,  Servicing  Compensation,
              Trustee Fees and Trust Fund expenses; and

       (iv)   the amount of any Liquidation  Expenses incurred by the Trust Fund
              in connection with such purchase;

provided,  that, such Holder,  at its expense,  has provided the Trustee with an
Opinion of Counsel to the effect  that such  purchase  would not (x) result in a
gain which would be subject to the tax on net income  derived  from  "prohibited
transactions"  imposed by Code Section  860F(a)(1)  or  otherwise  result in the
imposition  of any other tax on the  Lower-Tier  REMIC or the  Upper-Tier  REMIC
under the REMIC  Provisions  or (y) cause  either  the  Upper-Tier  REMIC or the
Lower-Tier  REMIC to fail to  qualify  as a REMIC;  such  opinion  relying  upon
appraisals  of the fair market value (for the purposes of Section  860F(c)(1) of
the Code) of such Mortgage Loan by at least three Independent appraisers.

     Notwithstanding  the foregoing,  such Mortgage Loan may not be purchased if
the  fair  market  value  of the  Mortgage  Loan  is  greater  than  100% of the
outstanding principal balance of such Mortgage Loan.

     The Holder of 100% of the most subordinate Class of Certificates  (provided
that the  Class  B-7H  Certificates  shall  not be  considered  a Class for such
purposes) may purchase any Mortgage Loan on or after its  Anticipated  Repayment
Date under the same terms and conditions  hereunder as in the case of a purchase
by the  Holder  of the  Class LR  Certificates  if the  Holder  of the  Class LR
Certificates  either (i)  notifies the Holder of the most  subordinate  Class of
Certificates  that it will not purchase  such Mortgage Loan or (ii) does not, in
fact, purchase such Mortgage Loan on its Anticipated Repayment Date.

     The  proceeds of any such  purchase  hereunder  shall be  deposited  in the
Collection Account and disbursed as provided herein.

     Notwithstanding anything to the contrary contained in this Section 9.01(g),
if the Class LR or most  subordinate  Class of Certificates  shall be held by an
Affiliate of the Depositor,  such Affiliate may not exercise any of the purchase
rights  under this Section  9.01(g)  with respect to a Mortgage  Loan that is in
default.

                            MISCELLANEOUS PROVISIONS

     SECTION 10.01. Counterparts.

     This   Agreement   may  be  executed   simultaneously   in  any  number  of
counterparts,  each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.

     SECTION 10.02. Limitation on Rights of Certificateholders.

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

     No  Certificateholder  shall have any right to vote  (except  as  expressly
provided  for  herein) or in any manner  otherwise  control  the  operation  and
management  of the Trust Fund, or the  obligations  of the parties  hereto,  nor
shall anything herein set forth, or contained in the terms of 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 person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

     No Certificateholder  shall have any right to institute any suit, action or
proceeding  in equity or at law upon or under or with respect to this  Agreement
or any  Mortgage  Loan,  unless such Holder  previously  shall have given to the
Trustee  a  written  notice  of  default  and of  the  continuance  thereof,  as
hereinbefore provided, and unless also the Holders of Certificates  representing
Percentage  Interests  of at least 25% of each  affected  Class of  Certificates
shall have made written request upon the Trustee to institute such action,  suit
or proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs,  expenses
and liabilities to be incurred therein or thereby,  and the Trustee, for 60 days
after its receipt of such  notice,  request and offer of  indemnity,  shall have
neglected or refused to institute  any such action,  suit or  proceeding.  It is
understood and intended, and expressly covenanted by each Certificateholder with
every other  Certificateholder  and the Trustee,  that no one or more Holders of
Certificates  of any Class shall have any right in any manner whatever by virtue
of any provision of this Agreement to affect, disturb or prejudice the rights of
the  Holders of any other of such  Certificates,  or to obtain or seek to obtain
priority over or  preference  to any other such Holder,  or to enforce any right
under this  Agreement,  except in the manner herein  provided and for the equal,
ratable and common benefit of all Holders of Certificates of such Class. For the
protection and  enforcement  of the  provisions of this Section,  each and every
Certificateholder  and the  Trustee  shall be  entitled to such relief as can be
given either at law or in equity.

     SECTION 10.03. Governing Law.

     THIS AGREEMENT  SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE
OF NEW YORK AND THE  OBLIGATIONS,  RIGHTS AND REMEDIES OF THE PARTIES  HEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     SECTION 10.06. Notice to the Depositor and Each Rating Agency.

     (a) The Trustee  shall use its best efforts to promptly  provide  notice to

              the extent  collected  pursuant  to Section  3.03;  however,  with
              respect to Fitch,  the Servicer  shall  provide only the quarterly

              upon  request  (and with  respect to the  Special  Servicer,  such

     SECTION 10.07. Amendment.

     This Agreement or any Custodial  Agreement may be amended from time to time
by the Depositor, the Servicer, the Special Servicer, the Trustee and the Fiscal
Agent,  without  the consent of any of the  Certificateholders,  (i) to cure any
ambiguity,  (ii) to correct or supplement any provisions  herein or therein that
may be defective or inconsistent  with any other  provisions  herein or therein,
(iii) to amend any  provision  hereof to the extent  necessary  or  desirable to
maintain  the  rating or  ratings  assigned  to each of the  Classes  of Regular
Certificates  by each Rating Agency,  (iv) to amend or supplement any provisions
herein or therein that shall not  adversely  affect in any material  respect the
interests  of any  Certificateholder  not  consenting  thereto,  as evidenced in
writing by an Opinion of Counsel,  at the expense of the party  requesting  such
amendment or confirmation in writing from each Rating Agency that such amendment
or supplement will not result in a  qualification,  withdrawal or downgrading of
the  then-current  ratings  assigned  to  the  Certificates,  (v)  to  amend  or
supplement any provisions  hereof to the extent necessary or desirable to enable
the  Certificates  to be listed in the  Luxembourg  Stock  Exchange  (Bureau  de
Luxembourg)  or (vi) to make any other  provisions  with  respect  to matters or
questions arising under this Agreement, which shall not be inconsistent with the
provisions of this  Agreement and will not result in a downgrade,  qualification
or  withdrawal  of the then  current  rating or  ratings  then  assigned  to any
outstanding  Class of  Certificates,  as  confirmed  by each  Rating  Agency  in
writing.

     This Agreement or any Custodial  Agreement may also be amended from time to
time by the Depositor,  the Servicer,  the Special Servicer, the Trustee and the
Fiscal  Agent with the  consent of the Holders of each of the Classes of Regular
Certificates  representing not less than 66-2/3% of the Percentage  Interests of
each Class of  Certificates  affected by the amendment for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of  this   Agreement   or  of   modifying  in  any  manner  the  rights  of  the
Certificateholders; provided, however, that no such amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction under this
              Agreement,  without the consent of the Holders of all Certificates
              representing  all of the  Percentage  Interests  of the  Class  or
              Classes affected hereby;

       (iii)  alter the Servicing  Standard or the  obligations of the Servicer,
              the Special  Servicer,  the Trustee or the Fiscal  Agent to make a
              P&I Advance or Property Advance without the consent of the Holders
              of all Certificates  representing all of the Percentage  Interests
              of the Class or Classes affected thereby; or

       (iv)   amend any section  hereof which  relates to the  amendment of this
              Agreement   without   the  consent  of  all  the  holders  of  all
              Certificates representing all Percentage Interests of the Class or
              Classes affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend this Agreement to modify, eliminate or add to any
of its  provisions  to such  extent  as  shall  be  necessary  to  maintain  the
qualification  of the Trust  REMIC as two  separate  REMICs,  or to prevent  the
imposition of any additional  material  state or local taxes,  at all times that
any  Certificates  are  outstanding;  provided,  however,  that such action,  as
evidenced by an Opinion of Counsel  (obtained at the expense of the Trust Fund),
is  necessary  or helpful  to  maintain  such  qualification  or to prevent  the
imposition  of any such taxes,  and would not  adversely  affect in any material
respect the interest of any Certificateholder.

     In the event that neither the Depositor nor any successor thereto,  if any,
is in existence,  any amendment under this Section 10.07 shall be effective with
the consent of the  Trustee,  the Fiscal  Agent,  the Special  Servicer  and the
Servicer,  in  writing,  and  to  the  extent  required  by  this  Section,  the
Certificateholders.  Promptly after the execution of any amendment, the Servicer
shall forward to the Trustee and the Trustee shall furnish written  notification
of the  substance of such  amendment to each  Certificateholder  and each Rating
Agency.

     It shall not be necessary for the consent of Certificateholders  under this
Section 10.07 to approve the particular form of any proposed  amendment,  but it
shall be sufficient if such consent  shall  approve the substance  thereof.  The
method of obtaining  such consents and of evidencing  the  authorization  of the
execution  thereof by  Certificateholders  shall be  subject to such  reasonable
regulations as the Trustee may prescribe;  provided,  however,  that such method
shall always be by affirmation and in writing.

     Notwithstanding  any  contrary  provision of this  Agreement,  no amendment
shall be made to this Agreement or any Custodial  Agreement unless, if requested
by the  Servicer  and/or the Trustee,  the  Servicer and the Trustee  shall have
received an Opinion of  Counsel,  at the  expense of the party  requesting  such
amendment (or, if such amendment is required by either Rating Agency to maintain
the rating issued by it or requested by the Trustee for any purpose described in
clause (i) or (ii) of the first sentence of this Section, then at the expense of
the Trust  Fund),  to the effect that such  amendment  will not cause either the
Upper-Tier  REMIC or Lower-Tier  REMIC to fail to qualify as a REMIC at any time
that any  Certificates are outstanding or cause a tax to be imposed on the Trust
Fund  under the  REMIC  Provisions  (other  than a tax at the  highest  marginal
corporate tax rate on net income from foreclosure property).

     Prior to the execution of any amendment to this  Agreement or any Custodial
Agreement,  the Trustee, the Fiscal Agent, the Special Servicer and the Servicer
may  request  and shall be  entitled  to rely  conclusively  upon an  Opinion of
Counsel,  at the expense of the party  requesting  such  amendment  (or, if such
amendment is required by either  Rating  Agency to maintain the rating issued by
it or  requested by the Trustee for any purpose  described in clause (i),  (ii),
(iii) or (v) (which do not modify or otherwise relate solely to the obligations,
duties or rights of the Trustee) of the first sentence of this Section,  then at
the expense of the Trust Fund) stating that the  execution of such  amendment is
authorized or permitted by this Agreement. The Trustee and the Fiscal Agent may,
but shall not be obligated to, enter into any such  amendment  which affects the
Trustee's  or the Fiscal  Agent's own rights,  duties or  immunities  under this
Agreement.

     SECTION 10.08. Confirmation of Intent.

     It is the express  intent of the parties  hereto that the conveyance of the
Trust Fund  (including  the Mortgage  Loans) by the  Depositor to the Trustee on
behalf of  Certificateholders  as contemplated by this Agreement and the sale by
the Depositor of the Certificates be, and be treated for all purposes as, a sale
by the  Depositor of the  undivided  portion of the  beneficial  interest in the
Trust Fund represented by the Certificates. 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 continue to be property of the Depositor then (a) this Agreement
shall also be deemed to be a security  agreement  under  applicable law; (b) the
transfer of the Trust Fund  provided for herein shall be deemed to be a grant by
the Depositor to the Trustee on behalf of Certificateholders of a first priority
security interest in all of the Depositor's  right, title and interest in and to
the Trust Fund and all amounts  payable to the holders of the Mortgage  Loans in
accordance with the terms thereof and all proceeds of the conversion,  voluntary
or  involuntary,  of the foregoing into cash,  instruments,  securities or other
property,  including,  without limitation, all amounts from time to time held or
invested  in  the  Collection  Account,  the  Distribution  Account,  Upper-Tier
Distribution Account,  Default Interest Distribution Account and Excess Interest
Distribution Account,  whether in the form of cash,  instruments,  securities or
other  property;  (c) the  possession  by the Trustee (or the  Custodian  on its
behalf) of Notes and such other  items of property  as  constitute  instruments,
money,  negotiable  documents or chattel paper shall be deemed to be "possession
by the secured party" for purposes of perfecting the security  interest pursuant
to Section 9-305 of the Delaware and Illinois  Uniform  Commercial Code; and (d)
notifications to Persons holding such property, and acknowledgments, receipts or
confirmations from Persons holding such property,  shall be deemed notifications
to,   or   acknowledgments,    receipts   or   confirmations   from,   financial
intermediaries, bailees or agents (as applicable) of the Trustee for the purpose
of perfecting such security interest under applicable law. Any assignment of the
interest of the Trustee pursuant to any provision hereof shall also be deemed to
be an assignment of any security  interest created hereby.  The Depositor shall,
and  upon  the  request  of the  Servicer,  the  Trustee  shall,  to the  extent
consistent with this Agreement (and at the expense of the Trust Fund), take such
actions as may be  necessary to ensure that,  if this  Agreement  were deemed to
create a security  interest in the Mortgage Loans,  such security interest would
be deemed to be a perfected security interest of first priority under applicable
law and will be maintained as such throughout the term of this Agreement.  It is
the intent of the  parties  that such a  security  interest  would be  effective
whether any of the Certificates are sold, pledged or assigned.

     SECTION 10.09. Streit Act.

     Any  provisions  required to be contained in this  Agreement by Section 126
and/or Section 130-k or Article 4-A of the New York Real Property Law are hereby
incorporated herein, and such provisions shall be in addition to those conferred
or imposed by this Agreement;  provided,  however,  that to the extent that such
Section 126 and/or Section 130-k shall not have any effect,  and if said Section
126 and/or  Section  130-k  should at any time be  repealed or cease to apply to
this  Agreement or be construed by judicial  decision to be  inapplicable,  said
Section 126 and/or Section 130-k shall cease to have any further effect upon the
provisions of this  Agreement.  In case of a conflict  between the provisions of
this Agreement and any mandatory  provisions of Article 4-A of the New York Real
Property  Law,  such  mandatory  provisions  of said Article 4-A shall  prevail,
provided that if said Article 4-A shall not apply to this  Agreement,  should at
any time be  repealed,  or cease to apply to this  Agreement  or be construed by
judicial decision to be inapplicable,  such mandatory provisions of such Article
4-A  shall  cease  to have  any  further  effect  upon  the  provisions  of this
Agreement.

     SECTION 10.10. No Intended Third-Party Beneficiaries.

     No Person other than a party to this  Agreement  and any  Certificateholder
shall have any rights with  respect to the  enforcement  of any of the rights or
obligations  hereunder.  Without  limiting  the  foregoing,  the parties to this
Agreement  specifically state that no Borrower,  property manager or other party
to a Mortgage Loan is an intended third-party beneficiary of this Agreement.

No.:  A-1A-

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-1A  Certificates.  The Trust Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1B,  Class A-1C,  Class A-CS1,  Class PS-1, Class A-2,
Class A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  A-1A  Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-1A  Certificates  for such  Distribution  Date, all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-1A Certificates will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided  that such  Certificateholder  hall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each

that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other

Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in

amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and

              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,

to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the

                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent

                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser

              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans

described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-1B  Certificates.  The Trust Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A,  Class A-1C,  Class A-CS1,  Class PS-1, Class A-2,
Class A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class LR Certificates (together with the A-1B Certificates,  the "Certificates";
the Holders of Certificates issued under the Pooling and Servicing Agreement are
collectively referred to herein as "Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-1B  Certificates  for such  Distribution  Date, all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-1B Certificates will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or

                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any

                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser

              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans

payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-1C  Certificates.  The Trust Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-CS1,  Class PS-1, Class A-1E,
Class A-2, Class A-3,  Class A-4,  Class A-5, Class A-8Z,  Class B-1, Class B-2,
Class B-3, Class B-3SC,  Class B-4, Class B-5, Class B-6, Class B-7, Class B-7H,
Class V-1, Class V-2, Class R and Class LR Certificates  (together with the A-1C
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-1C  Certificates  for such  Distribution  Date, all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-1C Certificates will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any

       (i)    the sum of

                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent

                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of

                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days

              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall

payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-2  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  A-2   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-2  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-2 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

No.:  A-3-

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-3  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  A-3   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-3  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-3 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not

                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such

Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section

created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been

Pooling and Servicing Agreement or be valid for any purpose.

No.:  A-4-

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-4  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  A-4   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-4  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-4 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate

supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be

              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates

              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,

to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the

payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class A-5  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  A-5   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class A-5  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-5 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are Class A-1A,  Class A-1B,  Class A-1C, Class PS-1, Class A-2, Class
A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4, Class
B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and Class
LR Certificates (together with the A-CS1 Certificates,  the "Certificates";  the
Holders of  Certificates  issued under the Pooling and  Servicing  Agreement are
collectively referred to herein as "Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     This Certificate represents a "regular interest" in a "real estate mortgage
investment  conduit,"  as those  terms are  defined,  respectively,  in Sections
860G(a)(1)  and 860D of the  Internal  Revenue  Code of l986,  as  amended,  and
certain other assets.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of interest then distributable,  if any, allocable to the Class
A-CS1  Certificates for such  Distribution  Date, all as more fully described in
the Pooling and Servicing Agreement. Holders of this Certificate may be entitled
to Prepayment Premiums, as provided in the Pooling and Servicing Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class A-CS1  Certificates  will be calculated based on a 360-day year consisting
of twelve 30-day months on the outstanding Notional Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.  The Interest  Accrual Period with respect to the
Distribution  Date occurring in April 1998 shall consist of the actual number of
11 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Notional Balance.  Such Certificates shall be
delivered by the Certificate Registrar in accordance with Section 5.02(e) of the
Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class PS-1  Certificates.  The Trust Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are Class A-1A, Class A-1B, Class A-1C, Class A-CS1,  Class A-2, Class
A-3,  Class A-4,  Class A-5,  Class B-1,  Class B-2, Class B-3, Class B-4, Class
B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and Class
LR Certificates  (together with the PS-1 Certificates,  the "Certificates";  the
Holders of  Certificates  issued under the Pooling and  Servicing  Agreement are
collectively referred to herein as "Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of interest then distributable,  if any, allocable to the Class
PS-1 Certificates for such Distribution Date, all as more fully described in the
Pooling and Servicing Agreement.  Holders of this Certificate may be entitled to
Prepayment Premiums, as provided in the Pooling and Servicing Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class PS-1 Certificates will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Notional Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.  The Interest  Accrual Period with respect to the
Distribution  Date occurring in April 1998 shall consist of the actual number of
11 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Notional Balance.  Such Certificates shall be
delivered by the Certificate Registrar in accordance with Section 5.02(e) of the
Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

               (A)  100% of the unpaid  principal  balance of each Mortgage Loan
                    included  in the Trust  Fund as of the last day of the month
                    preceding  such  Distribution  Date  (less any P&I  Advances
                    previously made on account of principal);

               (B)  the fair market value of all other property  included in the
                    Trust  Fund as of the last day of the month  preceding  such
                    Distribution Date, as determined by an Independent appraiser
                    acceptable  to the  Servicer as of the date not more than 30
                    days  prior  to the  last day of the  month  preceding  such
                    Distribution Date;

               (C)  all unpaid  interest  accrued on such  principal  balance of
                    each such  Mortgage  Loan  (including  for this  purpose any
                    Mortgage  Loan as to which  title to the  related  Mortgaged
                    Property has been  acquired) at the Mortgage  Rate (plus the
                    Excess Rate,  to the extent  applicable)  to the last day of
                    the month  preceding  such  Distribution  Date (less any P&I
                    Advances previously made on account of interest);

               (D)  the aggregate amount of unreimbursed Advances, with interest
                    thereon  at  the   Advance   Rate,   and  unpaid   Servicing
                    Compensation,  Special Servicing Compensation,  Trustee Fees
                    and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

No.:  B-1-

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class B-1  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-2, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-1   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-1  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-1 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary

prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early

                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such

              (C)    all unpaid  interest  accrued on such principal  balance of

                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such

              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class B-2  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-1, Class B-3, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-2   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-2  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-2 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage

Investor, the transferor shall reimburse the Trust Fund for any costs (including

any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,

Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the

                    preceding  such  Distribution  Date  (less any P&I  Advances
                    previously made on account of principal);

               (B)  the fair market value of all other property  included in the
                    Trust  Fund as of the last day of the month  preceding  such

                    Property has been  acquired) at the Mortgage  Rate (plus the
                    Excess Rate,  to the extent  applicable)  to the last day of

                    Advances previously made on account of interest);

               (D)  the aggregate amount of unreimbursed Advances, with interest
                    thereon  at  the   Advance   Rate,   and  unpaid   Servicing
                    Compensation,  Special Servicing Compensation,  Trustee Fees
                    and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such

              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section

payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

No.:  B-3-

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class B-3  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-1, Class B-2, Class B-4,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-3   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-3  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-3 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

No.:  B-4--

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class B-4  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-1, Class B-2, Class B-3,
Class B-5, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-4   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-4  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-4 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

No.:  B-5--

     This  certifies  that Cede & Co. is the  registered  owner of a  beneficial
ownership interest in a Trust Fund,  including the distributions to be made with
respect to the Class B-5  Certificates.  The Trust  Fund,  described  more fully
below, consists primarily of a pool of Mortgage Loans secured by first liens and
a second  lien on  commercial  properties  and held in trust by the  Trustee and
serviced by the Servicer. The Trust Fund was created, and the Mortgage Loans are
to be  serviced,  pursuant to the Pooling and  Servicing  Agreement  (as defined
below).  The Holder of this  Certificate,  by virtue of the  acceptance  hereof,
assents to the terms,  provisions  and  conditions  of the Pooling and Servicing
Agreement  and is bound  thereby.  Also issued  under the Pooling and  Servicing
Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-1, Class B-2, Class B-3,
Class B-4, Class B-6,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-5   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-5  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-5 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers

Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

              (i)    reduce in any manner the amount of, or delay the timing of,
                     payments  received on Mortgage  Loans which are required to
                     be  distributed on any  Certificate  without the consent of
                     all  the  holders  of  all  Certificates  representing  all
                     Percentage  Interests  of the  Class  or  Classes  affected
                     thereby;

              (ii)   change  the  percentages  of Voting  Rights of  Holders  of
                     Certificates which are required to consent to any action or
                     inaction under the Pooling and Servicing Agreement, without
                     the consent of the Holders of all Certificates representing
                     all of the  Percentage  Interests  of the Class or  Classes
                     affected hereby;

              (iii)  alter the  Servicing  Standard set forth in the Pooling and
                     Servicing Agreement or the obligations of the Servicer, the
                     Special Servicer, the Trustee or the Fiscal Agent to make a
                     P&I Advance or Property  Advance without the consent of the
                     Holders  of  all  Certificates   representing  all  of  the
                     Percentage  Interests  of the  Class  or  Classes  affected

              (iv)   amend any section of the Pooling  and  Servicing  Agreement
                     which relates to the amendment of the Pooling and Servicing
                     Agreement  without  the  consent of all the  holders of all
                     Certificates  representing all Percentage  Interests of the
                     Class or Classes affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,

Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the

                            last day of the month  preceding  such  Distribution
                            Date  (less  any  P&I  Advances  previously  made on

                            the related Mortgaged Property has been acquired) at
                            the  Mortgage  Rate  (plus the Excess  Rate,  to the
                            extent  applicable)  to the  last  day of the  month
                            preceding  such  Distribution  Date  (less  any  P&I

              (ii)   the aggregate fair market value of the Mortgage Loans,  and
                     all other property acquired in respect of any Mortgage Loan

                     than 30 days  prior to the last day of the month  preceding
                     such Distribution Date,  together with one month's interest
                     thereon at the Mortgage Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall

described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been

Agreement are the Class A-1A, Class A-1B,  Class A-1C, Class A-CS1,  Class PS-1,
Class A-2,  Class A-3,  Class A-4,  Class A-5,  Class B-1, Class B-2, Class B-3,
Class B-4, Class B-5,  Class B-7, Class B-7H,  Class V-1, Class V-2, Class R and
Class  LR  Certificates   (together  with  the  Class  B-6   Certificates,   the
"Certificates";  the  Holders  of  Certificates  issued  under the  Pooling  and
Servicing    Agreement    are    collectively     referred    to    herein    as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of principal and interest then distributable, if any, allocable
to the Class B-6  Certificates  for such  Distribution  Date,  all as more fully
described in the Pooling and Servicing  Agreement.  Holders of this  Certificate
may be entitled to Prepayment Premiums, as provided in the Pooling and Servicing
Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-6 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Certificate Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such  agreements,  (iii) to amend any provision of the Pooling and
Servicing  Agreement to the extent necessary or desirable to maintain the rating
or ratings  assigned  to each of the  Classes of  Regular  Certificates  by each
Rating Agency,  (iv) to amend or supplement  any  provisions in such  agreements
that shall not  adversely  affect in any material  respect the  interests of any
Certificateholder  not consenting thereto, as evidenced in writing by an Opinion
of  Counsel,   at  the  expense  of  the  party  requesting  such  amendment  or
confirmation  in  writing  from  each  Rating  Agency  that  such  amendment  or
supplement will not result in a qualification,  withdrawal or downgrading of the
then-current  ratings  assigned  to the  Certificates,  or (v) to make any other
provisions  with respect to matters or questions  arising  under the Pooling and
Servicing Agreement,  which shall not be inconsistent with the provisions of the
Pooling  and   Servicing   Agreement   and  will  not  result  in  a  downgrade,
qualification  or withdrawal of the then current rating or ratings then assigned
to any outstanding Class of Certificates,  as confirmed by each Rating Agency in
writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This certifies that Nomura Asset  Securities  Corporation is the registered
owner  of a  beneficial  ownership  interest  in a  Trust  Fund,  including  the
distributions to be made with respect to the Class B-7  Certificates.  The Trust
Fund, described more fully below, consists primarily of a pool of Mortgage Loans
secured by first liens and a second lien on  commercial  properties  and held in
trust by the Trustee and serviced by the  Servicer.  The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing
Agreement (as defined below).  The Holder of this Certificate,  by virtue of the
acceptance  hereof,  assents  to the terms,  provisions  and  conditions  of the
Pooling and  Servicing  Agreement  and is bound  thereby.  Also issued under the
Pooling and Servicing  Agreement are Class A-1A,  Class A-1B,  Class A-1C, Class
A-CS1,  Class PS-1, Class A-2, Class A-3, Class A-4, Class A-5, Class B-1, Class
B-2, Class B-3,  Class B-4,  Class B-5, Class B-6, Class B-7H,  Class V-1, Class
V-2,  Class  R  and  Class  LR   Certificates   (together  with  the  Class  B-7
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of interest then distributable,  if any, allocable to the Class
B-7 Certificates for such Distribution  Date, all as more fully described in the
Pooling and Servicing Agreement.  Holders of this Certificate may be entitled to
Prepayment Premiums, as provided in the Pooling and Servicing Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-7 Certificates  will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Notional Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Notional Balance.  Such Certificates shall be
delivered by the Certificate Registrar in accordance with Section 5.02(e) of the
Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as
confirmed by each Rating Agency in writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

              (i)    reduce in any manner the amount of, or delay the timing of,
                     payments  received on Mortgage  Loans which are required to
                     be  distributed on any  Certificate  without the consent of
                     all  the  holders  of  all  Certificates  representing  all
                     Percentage  Interests  of the  Class  or  Classes  affected
                     thereby;

              (ii)   change  the  percentages  of Voting  Rights of  Holders  of
                     Certificates which are required to consent to any action or
                     inaction under the Pooling and Servicing Agreement, without
                     the consent of the Holders of all Certificates representing
                     all of the  Percentage  Interests  of the Class or  Classes
                     affected hereby;

              (iii)  alter the  Servicing  Standard set forth in the Pooling and
                     Servicing Agreement or the obligations of the Servicer, the
                     Special Servicer, the Trustee or the Fiscal Agent to make a
                     P&I Advance or Property  Advance without the consent of the
                     Holders  of  all  Certificates   representing  all  of  the
                     Percentage  Interests  of the  Class  or  Classes  affected
                     thereby; or

              (iv)   amend any section of the Pooling  and  Servicing  Agreement
                     which relates to the amendment of the Pooling and Servicing
                     Agreement  without  the  consent of all the  holders of all
                     Certificates  representing all Percentage  Interests of the
                     Class or Classes affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

                            last day of the month  preceding  such  Distribution
                            Date  (less  any  P&I  Advances  previously  made on
                            account of principal);

                     (B)    the fair market value of all other property included
                            in the  Trust  Fund as of the last day of the  month

                            an Independent  appraiser acceptable to the Servicer
                            as of the date not  more  than 30 days  prior to the
                            last day of the month  preceding  such  Distribution
                            Date;

                     (C)    all  unpaid  interest   accrued  on  such  principal
                            balance of each such  Mortgage Loan  (including  for
                            this purpose any Mortgage  Loan as to which title to
                            the related Mortgaged Property has been acquired) at
                            the  Mortgage  Rate  (plus the Excess  Rate,  to the
                            extent  applicable)  to the  last  day of the  month
                            preceding  such  Distribution  Date  (less  any  P&I

              (ii)   the aggregate fair market value of the Mortgage Loans,  and
                     all other property acquired in respect of any Mortgage Loan
                     in the Trust Fund,  on the last day of the month  preceding
                     such  Distribution  Date, as  determined by an  Independent
                     appraiser  acceptable to the Servicer as of a date not more
                     than 30 days  prior to the last day of the month  preceding
                     such Distribution Date,  together with one month's interest
                     thereon at the Mortgage Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

     This certifies that Nomura Asset  Securities  Corporation is the registered
owner  of a  beneficial  ownership  interest  in a  Trust  Fund,  including  the
distributions to be made with respect to the Class B-7H Certificates.  The Trust
Fund, described more fully below, consists primarily of a pool of Mortgage Loans
secured by first liens and a second lien on  commercial  properties  and held in
trust by the Trustee and serviced by the  Servicer.  The Trust Fund was created,
and the Mortgage Loans are to be serviced, pursuant to the Pooling and Servicing
Agreement (as defined below).  The Holder of this Certificate,  by virtue of the
acceptance  hereof,  assents  to the terms,  provisions  and  conditions  of the
Pooling and  Servicing  Agreement  and is bound  thereby.  Also issued under the
Pooling and Servicing  Agreement are Class A-1A,  Class A-1B,  Class A-1C, Class
A-CS1,  Class PS-1, Class A-2, Class A-3, Class A-4, Class A-5, Class B-1, Class
B-2,  Class B-3,  Class B-4,  Class B-5,  Class B-6, Class B-7, Class V-1, Class
V-2,  Class  R  and  Class  LR  Certificates   (together  with  the  Class  B-7H
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate amount of interest then distributable,  if any, allocable to the Class
B-7H Certificates for such Distribution Date, all as more fully described in the
Pooling and Servicing Agreement.  Holders of this Certificate may be entitled to
Prepayment Premiums, as provided in the Pooling and Servicing Agreement.

     During each Interest  Accrual  Period (as defined  below),  interest on the
Class B-7H Certificates will be calculated based on a 360-day year consisting of
twelve 30-day months on the outstanding Notional Balance hereof.

     Interest  accrued on this  Certificate  during an Interest  Accrual Period,
plus the aggregate unpaid Interest  Shortfall with respect to this  Certificate,
if any, will be payable on the related  Distribution Date to the extent provided
in the Pooling and  Servicing  Agreement.  The  "Interest  Accrual  Period" with
respect to any Distribution  Date other than the Distribution  Date occurring on
April 17, 1998 commences on and includes the eleventh day of the month preceding
the month in which such  Distribution  Date occurs and ends on and  includes the
tenth day of the month in which such Distribution Date occurs, provided that the
first  Interest  Accrual  Period  shall  commence on the Cut-off Date and end on
April 10, 1998.  Each Interest  Accrual  Period other than the Interest  Accrual
Period with  respect to the  Distribution  Date  occurring  on April 17, 1998 is
assumed to consist of 30 days.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Notional Balance.  Such Certificates shall be
delivered by the Certificate Registrar in accordance with Section 5.02(e) of the
Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as

the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of

                     previously made on account of principal);

              (B)    the fair market value of all other property included in the

                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the

              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans

described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited

Servicing Agreement.

to the obligation to reimburse the Servicer, the Trustee or the Fiscal Agent, as
applicable, for interest on Advances, and such portion of the Trust Fund will be
treated as a grantor trust for federal income tax purposes.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     Pursuant to the terms of the Pooling and Servicing Agreement,  the Trustee,
or the Paying Agent on behalf of the Trustee,  will  distribute  (other than the
final distribution on any Certificate), on the fourth Business Day following the
eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate Net Default Interest,  if any, allocable to the Class V-1 Certificates
for such  Distribution  Date,  all as more fully  described  in the  Pooling and
Servicing Agreement.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all

Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as
confirmed by each Rating Agency in writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

              (i)    reduce in any manner the amount of, or delay the timing of,
                     payments  received on Mortgage  Loans which are required to
                     be  distributed on any  Certificate  without the consent of
                     all  the  holders  of  all  Certificates  representing  all
                     Percentage  Interests  of the  Class  or  Classes  affected
                     thereby;

              (ii)   change  the  percentages  of Voting  Rights of  Holders  of
                     Certificates which are required to consent to any action or
                     inaction under the Pooling and Servicing Agreement, without
                     the consent of the Holders of all Certificates representing
                     all of the  Percentage  Interests  of the Class or  Classes
                     affected hereby;

              (iii)  alter the  Servicing  Standard set forth in the Pooling and
                     Servicing Agreement or the obligations of the Servicer, the
                     Special Servicer, the Trustee or the Fiscal Agent to make a
                     P&I Advance or Property  Advance without the consent of the
                     Holders  of  all  Certificates   representing  all  of  the
                     Percentage  Interests  of the  Class  or  Classes  affected
                     thereby; or

              (iv)   amend any section of the Pooling  and  Servicing  Agreement
                     which relates to the amendment of the Pooling and Servicing
                     Agreement  without  the  consent of all the  holders of all
                     Certificates  representing all Percentage  Interests of the
                     Class or Classes affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the

                            last day of the month  preceding  such  Distribution
                            Date  (less  any  P&I  Advances  previously  made on

                            the  Mortgage  Rate  (plus the Excess  Rate,  to the

                     than 30 days  prior to the last day of the month  preceding
                     such Distribution Date,  together with one month's interest
                     thereon at the Mortgage Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the

eleventh day of such month (each such date, a  "Distribution  Date");  provided,
that if the  eleventh day of any month is not a Business  Day, the  Distribution
Date shall be the fifth  Business Day  following the eleventh day of such month,
to the Person in whose name this  Certificate  is  registered  as of the related
Record  Date,  an amount  equal to such  Person's  pro rata share  (based on the
Percentage  Interest  represented  by this  Certificate)  of that portion of the
aggregate Excess Interest,  if any,  allocable to the Class V-2 Certificates for
such Distribution Date, all as more fully described in the Pooling and Servicing
Agreement.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as
confirmed by each Rating Agency in writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

                                  EXHIBIT A-23

THIS  CERTIFICATE  DOES  NOT  REPRESENT  AN  OBLIGATION  OF OR  INTEREST  IN THE
DEPOSITOR, THE ORIGINATOR, THE SERVICER, THE TRUSTEE, THE FISCAL AGENT OR ANY OF
THEIR  RESPECTIVE  AFFILIATES.  NEITHER  THE  CERTIFICATES  NOR  THE  UNDERLYING
MORTGAGE  LOANS  ARE  INSURED  OR  GUARANTEED  BY  ANY  GOVERNMENTAL  AGENCY  OR
INSTRUMENTALITY.

FOR U.S. FEDERAL INCOME TAX PURPOSES,  THIS CERTIFICATE IS A "RESIDUAL INTEREST"
IN A "REAL  ESTATE  MORTGAGE  INVESTMENT  CONDUIT" AS THOSE  TERMS ARE  DEFINED,
RESPECTIVELY,  IN SECTIONS  860G(a)(2) AND 860D OF THE INTERNAL  REVENUE CODE OF
1986, AS AMENDED (THE "CODE").  A TRANSFEREE OF THIS CERTIFICATE,  BY ACCEPTANCE
HEREOF,  IS  DEEMED  TO  HAVE  ACCEPTED  THIS  CERTIFICATE  SUBJECT  TO  CERTAIN
RESTRICTIONS ON TRANSFERABILITY,  AS SET FORTH IN SECTION 5.02(l) OF THE POOLING
AND  SERVICING  AGREEMENT,  AND SHALL BE REQUIRED TO FURNISH AN AFFIDAVIT TO THE
TRANSFEROR AND THE TRUSTEE TO THE EFFECT THAT, AMONG OTHER THINGS, (A) IT IS NOT
A  DISQUALIFIED   ORGANIZATION,   AS  SUCH  TERM  IS  DEFINED  IN  CODE  SECTION
860(E)(e)(5),  OR AN AGENT (INCLUDING A BROKER,  NOMINEE OR OTHER MIDDLEMAN) FOR
SUCH DISQUALIFIED  ORGANIZATION AND IS OTHERWISE A PERMITTED TRANSFEREE,  (B) IT
HAS HISTORICALLY PAID ITS DEBTS AS THEY HAVE COME DUE AND INTENDS TO CONTINUE TO
PAY ITS  DEBTS AS THEY COME DUE IN THE  FUTURE,  AND (C) IT  INTENDS  TO PAY ANY
TAXES ASSOCIATED WITH HOLDING THIS CERTIFICATE AS THEY BECOME DUE. ANY PURPORTED
TRANSFER TO A DISQUALIFIED  ORGANIZATION OR OTHER PERSON THAT IS NOT A PERMITTED
TRANSFEREE OR OTHERWISE IN VIOLATION OF THESE  RESTRICTIONS  SHALL BE ABSOLUTELY
NULL AND VOID AND  SHALL  VEST NO RIGHTS IN ANY  PURPORTED  TRANSFEREE.  IF THIS
CERTIFICATE  REPRESENTS  A  "NON-ECONOMIC  RESIDUAL  INTEREST",  AS  DEFINED  IN
TREASURY REGULATIONS SECTION  1.860E-1(c),  TRANSFERS OF THIS CERTIFICATE MAY BE
DISREGARDED  FOR FEDERAL  INCOME TAX PURPOSES.  IN ORDER TO SATISFY A REGULATORY
SAFE HARBOR UNDER WHICH SUCH TRANSFERS WILL NOT BE  DISREGARDED,  THE TRANSFEROR
MAY BE  REQUIRED,  AMONG OTHER  THINGS,  TO SATISFY  ITSELF AS TO THE  FINANCIAL
CONDITION OF THE PROPOSED TRANSFEREE.

THE HOLDER OF THIS CERTIFICATE,  BY ACCEPTANCE  HEREOF, IS DEEMED TO HAVE AGREED
TO CONSENT TO ACT AS "TAX  MATTERS  PERSON" OF THE  UPPER-TIER  REMIC AND TO THE
APPOINTMENT  OF THE  TRUSTEE AS  ATTORNEY-IN-FACT  AND AGENT FOR THE TAX MATTERS
PERSON OR AS  OTHERWISE  PROVIDED  IN THE  POOLING AND  SERVICING  AGREEMENT  TO
PERFORM THE FUNCTIONS OF A "TAX MATTERS PARTNER" FOR PURPOSES OF SUBCHAPTER C OF
CHAPTER 63 OF SUBTITLE F OF THE CODE.

THIS  CERTIFICATE  HAS NOT  BEEN  AND  WILL  NOT BE  REGISTERED  UNDER  THE U.S.
SECURITIES  ACT OF 1933,  AS AMENDED (THE "1933  ACT"),  OR ANY STATE OR FOREIGN
SECURITIES LAW. THE HOLDER HEREOF, BY PURCHASING THIS  CERTIFICATE,  AGREES THAT
THIS CERTIFICATE MAY BE REOFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY
IN  COMPLIANCE  WITH THE  1933 ACT AND  OTHER  APPLICABLE  LAWS AND ONLY  (A)(1)
PURSUANT TO RULE 144A UNDER THE 1933 ACT TO AN  INSTITUTIONAL  INVESTOR THAT THE
HOLDER  REASONABLY  BELIEVES  IS A  QUALIFIED  INSTITUTIONAL  BUYER,  WITHIN THE

                       NOMURA ASSET SECURITIES CORPORATION
                 COMMERCIAL MORTGAGE PASS-THROUGH CERTIFICATES,
                             SERIES 1998-D6, CLASS R

CUSIP:  655356 JW 4                                    Percentage Interest: 100%

No.:  R--

     This certifies that Nomura Asset  Securities  Corporation is the registered
owner of the  Percentage  Interest  evidenced by this  Certificate  in the Trust
Fund.  The Class R  Certificateholder  is not  entitled to interest or principal
distributions.  The Class R  Certificateholder  will be  entitled to receive the
proceeds of the remaining  assets of the Upper-Tier  REMIC, if any, on the Final
Scheduled Distribution Date for the Certificates, after distributions in respect
of any accrued but unpaid interest on the Certificates  and after  distributions
in  reduction of principal  balance have reduced the  principal  balances of the
Certificates  to zero.  It is not  anticipated  that  there  will be any  assets
remaining  in  the  Upper-Tier  REMIC  or  Trust  Fund  on the  Final  Scheduled
Distribution Date following the distributions on the Regular  Certificates.  The
Trust Fund, described more fully below, consists primarily of a pool of Mortgage
Loans secured by first liens and a second lien on commercial properties and held
in trust by the  Trustee  and  serviced  by the  Servicer.  The  Trust  Fund was
created, and the Mortgage Loans are to be serviced,  pursuant to the Pooling and
Servicing  Agreement  (as defined  below).  The Holder of this  Certificate,  by
virtue of the acceptance hereof, assents to the terms, provisions and conditions
of the Pooling and Servicing  Agreement and is bound thereby.  Also issued under
the Pooling and Servicing  Agreement are the Class A-1A, Class A-1B, Class A-1C,
Class A-CS1,  Class PS-1, Class A-2, Class A-3, Class A-4, Class A-5, Class B-1,
Class B-2,  Class B-3,  Class B-4,  Class B-5, Class B-6, Class B-7, Class B-7H,
Class  V-1,  Class  V-2 and  Class LR  Certificates  (together  with the Class R
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     This  Certificate  represents  a  "residual  interest"  in a  "real  estate
mortgage  investment  conduit,"  as those terms are  defined,  respectively,  in
Sections 860G(a)(2) and 860D of the Code.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreements;  and (xi) the proceeds of any of the foregoing (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as
confirmed by each Rating Agency in writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage
              Rate.

     All costs and  expenses  incurred by any and all parties to the Pooling and
Servicing  Agreement  or by the Trust Fund  pursuant  to Section  9.01(c) of the
Pooling  and  Servicing  Agreement  shall be borne by the party  exercising  its
purchase rights  thereunder.  The Trustee shall be entitled to rely conclusively
on any  determination  made by an  Independent  appraiser  pursuant  to  Section
9.01(c) of the Pooling and Servicing Agreement.

     The  obligations  created by the  Pooling  and  Servicing  Agreement  shall
terminate upon the earliest to occur of (i) the repurchase of the Mortgage Loans
by the  Depositor,  the Servicer or the Holder of the Class LR  Certificates  as
described  above; or (ii) the later of (a) the receipt or collection of the last
payment  due on any  Mortgage  Loan  included  in the  Trust  Fund,  or (b)  the
liquidation and disposition  pursuant to the Pooling and Servicing  Agreement of
the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been
executed by the Trustee or on its behalf by the Authenticating  Agent, by manual
signature,  this  Certificate  shall not be entitled  to any  benefit  under the
Pooling and Servicing Agreement or be valid for any purpose.

                       NOMURA ASSET SECURITIES CORPORATION
                 COMMERCIAL MORTGAGE PASS-THROUGH CERTIFICATES,
                            SERIES 1998-D6, CLASS LR

CUSIP:                                                 Percentage Interest: 100%

No.: LR--

     This  certifies  that Nomura Asset Capital  Corporation  is the  registered
owner of the  Percentage  Interest  evidenced by this  Certificate  in the Trust
Fund.  The Class LR  Certificateholder  is not entitled to interest or principal
distributions.  The Class LR  Certificateholder  will be entitled to receive the
proceeds of the remaining  assets of the Lower-Tier  REMIC, if any, on the Final
Scheduled Distribution Date for the Certificates, after distributions in respect
of any accrued but unpaid interest on the Certificates  and after  distributions
in  reduction of principal  balance have reduced the  principal  balances of the
Certificates  to zero.  It is not  anticipated  that  there  will be any  assets
remaining  in  the  Lower-Tier  REMIC  or  Trust  Fund  on the  Final  Scheduled
Distribution Date following the distributions on the Regular  Certificates.  The
Trust Fund was created,  and the Mortgage Loans are to be serviced,  pursuant to
the Pooling and  Servicing  Agreement  (as  defined  below).  The Holder of this
Certificate,  by  virtue  of  the  acceptance  hereof,  assents  to  the  terms,
provisions  and  conditions of the Pooling and Servicing  Agreement and is bound
thereby.  Also issued under the Pooling and  Servicing  Agreement  are the Class
A-1A,  Class A-1B,  Class A-1C,  Class A-CS1,  Class PS-1, Class A-2, Class A-3,
Class A-4,  Class A-5,  Class B-1,  Class B-2,  Class B-3, Class B-4, Class B-5,
Class B-6, Class B-7, Class B-7H,  Class V-1, Class V-2 and Class R Certificates
(together with the Class LR  Certificates,  the  "Certificates";  the Holders of
Certificates  issued under the Pooling and Servicing  Agreement are collectively
referred to herein as "Certificateholders").

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and  Servicing  Agreement  dated as of March 30, 1998 (the "Pooling
and Servicing Agreement"),  by and among Nomura Asset Securities Corporation, as
Depositor,  AMRESCO  Services,  L.P., as Servicer,  CRIIMI MAE Services  Limited
Partnership,  as Special  Servicer,  LaSalle National Bank, as Trustee,  and ABN
AMRO Bank N.V., as Fiscal Agent. To the extent not defined  herein,  capitalized
terms used herein  shall have the meanings  assigned  thereto in the Pooling and
Servicing Agreement.

     This  Certificate  represents  a  "residual  interest"  in a  "real  estate
mortgage  investment  conduit,"  as those terms are  defined,  respectively,  in
Sections 860G(a)(2) and 860D of the Code.

     The Trustee makes no representation or warranty as to any of the statements
contained  herein or the  validity or  sufficiency  of the  Certificates  or the
Mortgage  Loans and has executed  this  Certificate  in its limited  capacity as
Trustee under the Pooling and Servicing Agreement.

     All  distributions  (other than the final  distribution on any Certificate)
will be made by the Paying Agent to the persons in whose names the  Certificates
are  registered at the close of business on each Record Date,  which will be the
tenth day of the month in which the related Distribution Date occurs or, if such
day is not a Business Day, the preceding Business Day. Such distributions  shall
be made on each  Distribution  Date  other  than  the  Termination  Date to each
Certificateholder  of record on the related Record Date by check mailed by first
class mail to the address set forth  therefor in the  Certificate  Register  or,
provided that such  Certificateholder  shall have provided the Paying Agent with
wire  instructions  in writing at least five  Business Days prior to the related
Record Date, by wire transfer of immediately  available  funds to the account of
such  Certificateholder  at a bank or other entity  located in the United States
and having  appropriate  facilities  therefor.  The final  distribution  on each
Certificate  shall  be  made in like  manner,  but  only  upon  presentment  and
surrender of such  Certificate  at the office of the Trustee or its agent (which
may be the  Paying  Agent or the  Certificate  Registrar  acting as such  agent)
maintained  in the  Borough  of  Manhattan  that is  specified  in the notice to
Certificateholders of such final distribution.

     Any funds not  distributed  on the  Termination  Date because of failure of
Certificateholders  to tender their  Certificates shall be set aside and held in
trust for the account of the  non-tendering  Certificateholders,  whereupon  the
Trust  Fund  shall  terminate.  If any  Certificates  as to which  notice of the
Termination  Date has been given  pursuant  to Section  9.01 of the  Pooling and
Servicing  Agreement shall not have been surrendered for cancellation within six
months after the time specified in such notice,  the Trustee shall mail a second
notice to the remaining Certificateholders, at their last addresses shown in the
Certificate  Register, to surrender their Certificates for cancellation in order
to receive,  from such funds held, the final  distribution with respect thereto.
If within one year after the second notice any  Certificate  shall not have been
surrendered  for  cancellation,  the Trustee may,  directly or through an agent,
take appropriate  steps to contact the remaining  Certificateholders  concerning
surrender  of their  Certificates.  The costs and expenses of  maintaining  such
funds and of contacting Certificateholders shall be paid out of the assets which
remain held. If within two years after the second notice any Certificates  shall
not have been  surrendered for  cancellation,  the Paying Agent shall pay to the
Trustee all amounts  distributable to the Holders thereof, and the Trustee shall
thereafter  hold such amounts for the benefit of such Holders  until the earlier
of (i) its termination as Trustee under the Pooling and Servicing  Agreement and
the transfer of such amounts to a successor  Trustee or (ii) the  termination of
the   Trust   Fund  and   distribution   of  such   amounts   to  the   Class  R
Certificateholders.   No   interest   shall   accrue  or  be   payable   to  any
Certificateholder  on any  amount  held as a result of such  Certificateholder's
failure to surrender its  Certificate(s) for final payment thereof in accordance
with Section 9.01 of the Pooling and Servicing Agreement. Such funds held by the
Trustee  may be invested  under  certain  circumstances,  and subject to certain
conditions as specified in the Pooling and Servicing Agreement.

     This  Certificate  is limited in right of payment to,  among other  things,
certain  collections  and recoveries in respect of the Mortgage  Loans,  as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     As provided in the Pooling and Servicing Agreement, the Trust Fund includes
(i) such  Mortgage  Loans as from time to time are  subject to the  Pooling  and
Servicing Agreement, together with the Mortgage Files relating thereto; (ii) all
scheduled or  unscheduled  payments on or collections in respect of the Mortgage
Loans due after the Cut-off  Date;  (iii) any REO  Property;  (iv) all  revenues
received  in  respect  of any REO  Property;  (v) the  Servicer's,  the  Special
Servicer's and the Trustee's rights under the insurance policies with respect to
the  Mortgage  Loans  required  to be  maintained  pursuant  to the  Pooling and
Servicing  Agreement and any proceeds  thereof;  (vi) any Assignments of Leases,
Rents  and  Profits  and any  security  agreements;  (vii)  any  indemnities  or
guaranties  given as  additional  security  for any Mortgage  Loans;  (viii) all
assets  deposited in the Lock-Box  Accounts,  Cash Collateral  Accounts,  Escrow
Accounts and Reserve  Accounts  (to the extent such assets in such  accounts are
not  assets  of  the  respective   Borrowers),   the  Collection  Account,   the
Distribution  Account, the Upper-Tier  Distribution Account, the Excess Interest
Distribution  Account,  the Interest  Reserve  Account and the Default  Interest
Distribution  Account,  including  reinvestment  income;  (ix) any environmental
indemnity  agreements relating to the Mortgaged  Properties;  (x) the rights and
remedies  under the Mortgage Loan Purchase and Sale  Agreements  and  Bloomfield
Purchase  Agreement;  and (xi) the proceeds of any of the foregoing  (other than
any  interest  earned on  deposits in the  Lock-Box  Accounts,  Cash  Collateral
Accounts,  Escrow Accounts and any Reserve Accounts, to the extent such interest
belongs to the related  Borrower).  As  provided  in the  Pooling and  Servicing
Agreement,  withdrawals  may be made  from  certain  of the  above-accounts  for
purposes other than distributions to Certificateholders.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement,  and reference is made to the Pooling and Servicing Agreement for the
interests,  rights,  benefits,  obligations and duties evidenced hereby, and the
limitations thereon, and the rights, duties and immunities of the Trustee.

     As provided in the Pooling and  Servicing  Agreement and subject to certain
limitations set forth therein,  this Certificate is transferable or exchangeable
only upon  surrender of this  Certificate  to the  Certificate  Registrar at the
Corporate Trust Office together with an assignment and transfer (executed by the
Holder or his duly authorized attorney),  subject to the requirements in Article
V of the Pooling and Servicing  Agreement.  Upon surrender for  registration  of
transfer of this  Certificate,  subject to the  requirements of Article V of the
Pooling  and   Servicing   Agreement,   the  Trustee   shall   execute  and  the
Authenticating  Agent  shall  duly  authenticate  in the name of the  designated
transferee  or  transferees,   one  or  more  new   Certificates  in  authorized
denominations of a like aggregate  Certificate Balance.  Such Certificates shall
be delivered by the Certificate  Registrar in accordance with Section 5.02(e) of
the Pooling and Servicing Agreement.

     Prior to due presentation of this Certificate for registration of transfer,
the Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the  Certificate
Registrar, any Paying Agent and any agent of any of them may treat the Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Servicer,  the Trustee,  the Fiscal Agent,  the
Certificate  Registrar,  any  Paying  Agent or any agent of any of them shall be
affected by notice to the contrary.

     No fee or service charge shall be imposed by the Certificate  Registrar for
its services in respect of any registration of transfer or exchange  referred to
in Section 5.02 of the Pooling and Servicing  Agreement other than for transfers
to  Institutional  Accredited  Investors as provided in Section  5.02(h) of that
Agreement.  In  connection  with any  transfer  to an  Institutional  Accredited
Investor, the transferor shall reimburse the Trust Fund for any costs (including
the cost of the Certificate  Registrar's  counsel's  review of the documents and
any legal opinions, submitted by the transferor or transferee to the Certificate
Registrar  as  provided  herein)  incurred  by  the  Certificate   Registrar  in
connection with such transfer.  The Certificate Registrar may require payment by
each  transferor  of a sum  sufficient  to  cover  any  tax,  expense  or  other
governmental charge payable in connection with any such transfer.

     The Pooling and  Servicing  Agreement  or any  Custodial  Agreement  may be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the  Trustee  and  the  Fiscal  Agent,   without  the  consent  of  any  of  the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions  therein  that  may be  defective  or  inconsistent  with  any  other
provisions in such agreements, (iii) to amend any provision hereof to the extent
necessary or desirable to maintain the rating or ratings assigned to each of the
Classes  of  Regular  Certificates  by each  Rating  Agency,  (iv) to  amend  or
supplement any provisions in such agreements that shall not adversely  affect in
any material  respect the  interests  of any  Certificateholder  not  consenting
thereto, as evidenced in writing by an Opinion of Counsel, at the expense of the
party  requesting  such  amendment or  confirmation  in writing from each Rating
Agency that such  amendment or  supplement  will not result in a  qualification,
withdrawal  or  downgrading  of  the   then-current   ratings  assigned  to  the
Certificates,  or (v) to make any other  provisions  with  respect to matters or
questions arising under the Pooling and Servicing Agreement,  which shall not be
inconsistent with the provisions of the Pooling and Servicing Agreement and will
not result in a  downgrade,  qualification  or  withdrawal  of the then  current
rating or ratings then assigned to any  outstanding  Class of  Certificates,  as
confirmed by each Rating Agency in writing.

     The Pooling and Servicing  Agreement or any Custodial Agreement may also be
amended from time to time by the Depositor,  the Servicer, the Special Servicer,
the Trustee and the Fiscal  Agent with the consent of the Holders of each of the
Classes  of  Regular  Certificates  representing  not less than  66-2/3%  of the
Percentage Interests of each Class of Certificates affected by the amendment for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Pooling and Servicing  Agreement or of modifying in
any manner the rights of the Certificateholders; provided, however, that no such
amendment shall:

       (i)    reduce in any  manner  the  amount  of, or delay  the  timing  of,
              payments  received  on  Mortgage  Loans  which are  required to be
              distributed  on any  Certificate  without  the  consent of all the
              holders of all Certificates  representing all Percentage Interests
              of the Class or Classes affected thereby;

       (ii)   change the percentages of Voting Rights of Holders of Certificates
              which are required to consent to any action or inaction  under the
              Pooling  and  Servicing  Agreement,  without  the  consent  of the
              Holders of all  Certificates  representing  all of the  Percentage
              Interests of the Class or Classes affected hereby;

       (iii)  alter  the  Servicing  Standard  set  forth  in  the  Pooling  and
              Servicing  Agreement  or  the  obligations  of the  Servicer,  the
              Special  Servicer,  the Trustee or the Fiscal  Agent to make a P&I
              Advance or Property  Advance without the consent of the Holders of
              all Certificates  representing all of the Percentage  Interests of
              the Class or Classes affected thereby; or

       (iv)   amend any  section of the Pooling and  Servicing  Agreement  which
              relates to the  amendment of the Pooling and  Servicing  Agreement
              without  the  consent  of all  the  holders  of  all  Certificates
              representing  all  Percentage  Interests  of the Class or  Classes
              affected thereby.

     Further, the Depositor, the Servicer, the Special Servicer, the Trustee and
the Fiscal Agent, at any time and from time to time,  without the consent of the
Certificateholders,  may amend the Pooling and  Servicing  Agreement  to modify,
eliminate or add to any of its  provisions  to such extent as shall be necessary
to maintain the  qualification of the Trust REMIC as two separate REMICs,  or to
prevent the imposition of any additional  material state or local taxes,  at all
times  that any  Certificates  are  outstanding;  provided,  however,  that such
action,  as evidenced  by an Opinion of Counsel  (obtained at the expense of the
Trust  Fund),  is  necessary  or helpful to maintain  such  qualification  or to
prevent the imposition of any such taxes,  and would not adversely affect in any
material respect the interest of any Certificateholder.

     The  Depositor,  and if the  Depositor  does not exercise  the option,  the
Servicer  and, if neither the Servicer nor the  Depositor  exercises the option,
the  holders  of the  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest  in  such  Class  and,  if such  holders  of the  Class  LR
Certificates  fail to exercise such option,  the Special  Servicer may effect an
early termination of the Trust Fund, upon not less than 30 days' prior Notice of
Termination  given to the  Trustee and  Servicer  any time on or after the Early
Termination  Notice  Date  (defined  as any  date  as of  which  either  (a) the
aggregate  Stated  Principal  Balance of the Mortgage Loans is less than 1.0% of
the aggregate Stated  Principal  Balance of the Mortgage Loans as of the Cut-off
Date or (b) if outstanding  Mortgage  Loans  remaining in the Trust Fund consist
solely of the Circuit City Credit Lease Loans,  Carmax Credit Lease Loans and/or
the Parkview House Apartments Loan) specifying the Anticipated Termination Date,
by  purchasing  on such date all, but not less than all, of the  Mortgage  Loans
then  included in the Trust Fund,  and all  property  acquired in respect of any
Mortgage Loan, at a purchase price,  payable in cash, equal to not less than the
greater of:

       (i)    the sum of

              (A)    100% of the unpaid principal  balance of each Mortgage Loan
                     included  in the Trust Fund as of the last day of the month
                     preceding  such  Distribution  Date (less any P&I  Advances
                     previously made on account of principal);

              (B)    the fair market value of all other property included in the
                     Trust Fund as of the last day of the month  preceding  such
                     Distribution   Date,  as   determined  by  an   Independent
                     appraiser  acceptable  to the  Servicer  as of the date not
                     more  than 30  days  prior  to the  last  day of the  month
                     preceding such Distribution Date;

              (C)    all unpaid  interest  accrued on such principal  balance of
                     each such  Mortgage  Loan  (including  for this purpose any
                     Mortgage  Loan as to which title to the  related  Mortgaged
                     Property has been  acquired) at the Mortgage Rate (plus the
                     Excess Rate, to the extent  applicable)  to the last day of
                     the month  preceding such  Distribution  Date (less any P&I
                     Advances previously made on account of interest);

              (D)    the  aggregate  amount  of  unreimbursed   Advances,   with
                     interest  thereon at the Advance Rate, and unpaid Servicing
                     Compensation,  Special Servicing Compensation, Trustee Fees
                     and Trust Fund expenses; and

       (ii)   the  aggregate  fair market value of the Mortgage  Loans,  and all
              other  property  acquired in respect of any  Mortgage  Loan in the
              Trust  Fund,  on  the  last  day  of  the  month   preceding  such
              Distribution  Date,  as  determined  by an  Independent  appraiser
              acceptable  to the  Servicer  as of a date not  more  than 30 days
              prior to the last day of the  month  preceding  such  Distribution
              Date,  together with one month's  interest thereon at the Mortgage

     All costs and  expenses  incurred by any and all parties to the Pooling and

the last  asset held by the Trust  Fund.  In no event,  however,  will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy, the late ambassador of the United States to the United Kingdom,  living
on the date hereof.

     Unless the  Certificate  of  Authentication  on this  Certificate  has been

Pooling and Servicing Agreement or be valid for any purpose.

          Re:  Transfer  of  Nomura  Asset  Securities  Corporation,  Commercial
               Mortgage Pass-Through Certificates, Series 1998-D6

Ladies and Gentlemen:

     This  letter is  delivered  pursuant  to Section  5.02 of the  Pooling  and
Servicing  Agreement  dated as of March 30,  1998 (the  "Pooling  and  Servicing
Agreement"),  by and among Nomura Asset  Securities  Corporation,  as depositor,
AMRESCO Services, L.P., as servicer, CRIIMI MAE Services Limited Partnership, as
special  servicer,  LaSalle National Bank, as trustee (the  "Trustee"),  and ABN
AMRO Bank N.V., as fiscal agent (the "Fiscal  Agent"),  on behalf of the holders
of  Nomura  Asset  Securities  Corporation,   Commercial  Mortgage  Pass-Through
Certificates,  Series  1998-D6  (the  "Certificates")  in  connection  with  the
transfer  by   _________________   (the  "Seller")  to  the   undersigned   (the
"Purchaser")  of   [$_______________   aggregate   Certificate   Balance]  [___%
Percentage  Interest] of Class Certificates (such registered  interest being the
"Certificate").  Capitalized  terms used but not defined  herein  shall have the
meanings ascribed thereto in the Pooling and Servicing Agreement.

     In connection  with such transfer,  the undersigned  hereby  represents and
warrants to you as follows [check one of the following]:

         |  |  [For   Institutional   Accredited   Investors  only]  We  are  an
               "institutional   accredited  investor"  (an  entity  meeting  the
               requirements of Rule  501(a)(1),  (2), (3) or (7) of Regulation D
               under the  Securities  Act of 1933,  as amended (the  "Securities
               Act")) and have such  knowledge  and  experience in financial and
               business  matters as to be capable of  evaluating  the merits and
               risks  of our  investment  in  the  Certificate,  and we and  any
               accounts  for  which  we are  acting  are  each  able to bear the
               economic  risk of our or its  investment.  We are  acquiring  the
               Certificate  purchased  by us for our own  account  or for one or
               more  accounts  (each of which  is an  "institutional  accredited
               investor")  as to each  of  which  we  exercise  sole  investment
               discretion.  The  Purchaser  hereby  undertakes  to reimburse the
               Trust  for any  costs  incurred  by it in  connection  with  this
               transfer.

         |  |  [For  Qualified  Institutional  Buyers  only] The  Purchaser is a
               "qualified  institutional  buyer" within the meaning of Rule 144A
               ("Rule 144A")  promulgated  under the  Securities Act of 1933, as
               amended (the  "Securities  Act"). The Purchaser is aware that the
               transfer  is  being  made  in  reliance  on  Rule  144A,  and the
               Purchaser  has had the  opportunity  to  obtain  the  information
               required to be provided  pursuant to paragraph  (d)(4)(i) of Rule
               144A.

         |  | [For Affiliated  Persons Only] The Purchaser is a person involved
               in the organization or operation of the issuer or an affiliate of
               such a person,  as defined in Rule 405 of the  Securities  Act of
               1933, as amended (the "Securities Act").

     2.  The  Purchaser's  intention  is to  acquire  the  Certificate  (a)  for
investment for the  Purchaser's  own account or (b) for resale to (i) "qualified
institutional buyers" in transactions under Rule 144A, or (ii) to "institutional
accredited  investors"  meeting the requirements of Rule 501(a)(1),  (2), (3) or
(7) of Regulation D promulgated  under the Securities Act, pursuant to any other
exemption from the  registration  requirements of the Securities Act, subject in
the case of this clause (ii) to (a) the receipt by the Certificate  Registrar of
a letter  substantially  in the form hereof,  (b) the receipt by the Certificate
Registrar of an opinion of counsel acceptable to the Certificate  Registrar that
such reoffer,  resale,  pledge or transfer is in compliance  with the Securities
Act,  (c) the  receipt  by the  Certificate  Registrar  of such  other  evidence
acceptable to the  Certificate  Registrar that such reoffer,  resale,  pledge or
transfer is in compliance with the Securities Act and other applicable laws, and
(d) a written undertaking to reimburse the Trust for any costs incurred by it in
connection with the proposed transfer.  It understands that the Certificate (and
any  subsequent  Individual  Certificate)  has not  been  registered  under  the
Securities  Act,  by  reason  of a  specified  exemption  from the  registration
provisions of the  Securities  Act which depends upon,  among other things,  the
bona fide nature of the  Purchaser's  investment  intent (or intent to resell to
only certain investors in certain exempted transactions) as expressed herein.

     3. The Purchaser  acknowledges  that the  Certificate  (and any Certificate
issued on transfer or exchange  thereof)  has not been  registered  or qualified
under  the  Securities  Act or the  securities  laws of any  State or any  other
jurisdiction,  and that the Certificate cannot be resold unless it is registered
or  qualified  thereunder  or unless an  exemption  from  such  registration  or
qualification is available.

     4. The Purchaser has reviewed the Private Placement  Memorandum dated March
30, 1998, relating to the Certificates (the "Private Placement  Memorandum") and
the  agreements  and  other  materials  referred  to  therein  and  has  had the
opportunity  to ask  questions  and  receive  answers  concerning  the terms and
conditions of the transactions contemplated by the Private Placement Memorandum.

     5. The Purchaser hereby  undertakes to be bound by the terms and conditions
of the  Pooling  and  Servicing  Agreement  in its  capacity  as an  owner of an
Individual   Certificate  or   Certificates,   as  the  case  may  be  (each,  a
"Certificateholder"),  in all respects as if it were a signatory  thereto.  This
undertaking is made for the benefit of the Trust, the Certificate  Registrar and
all Certificateholders present and future.

     6. The  Purchaser  will not sell or  otherwise  transfer any portion of the
Certificate, except in compliance with Section 5.02 of the Pooling and Servicing
Agreement.

     7.  Check one of the following:*

*  Each Purchaser must include one of the two alternative certifications.

         |  |  The  Purchaser is a "U.S.  Person" and it has attached  hereto an
               Internal Revenue Service ("IRS") Form W-9 (or successor form).

         |  |  The Purchaser is not a U.S.  Person and under  applicable  law in
               effect  on the date  hereof,  no  taxes  will be  required  to be
               withheld  by  the   Trustee  (or  its  agent)  with   respect  to
               distributions  to be made on the  Certificate.  The Purchaser has
               attached  hereto  either  (i) a duly  executed  IRS  Form W-8 (or
               successor   form),   which   identifies  such  Purchaser  as  the
               beneficial   owner  of  the  Certificate  and  states  that  such
               Purchaser is not a U.S.  Person or (ii) two duly executed  copies
               of IRS  Form  4224  (or  successor  form),  which  identify  such
               Purchaser as the beneficial  owner of the  Certificate  and state
               that interest and original issue discount on the  Certificate and
               Permitted  Investments  is,  or is  expected  to be,  effectively
               connected with a U.S. trade or business.  The Purchaser agrees to
               provide to the Certificate Registrar updated IRS Forms W-8 or IRS
               Forms  4224,  as the case may be, any  applicable  successor  IRS
               forms, or such other certifications as the Certificate  Registrar
               may reasonably  request,  on or before the date that any such IRS
               form or certification  expires or becomes  obsolete,  or promptly
               after the occurrence of any event  requiring a change in the most
               recent  IRS  form  of  certification   furnished  by  it  to  the
               Certificate Registrar.

For this purpose, "U.S. Person" means a citizen or resident of the United States
for U.S. federal income tax purposes, a corporation,  partnership (except to the
extent provided in applicable  Treasury  Regulations) or other entity created or
organized  in or under the laws of the  United  States  or any of its  political
subdivisions,  an estate the income of which is subject to U.S.  federal  income
taxation  regardless  of its  source,  or a trust if a court  within  the United
States is able to exercise primary  supervision over the  administration of such
trust,  and one or more United States  fiduciaries have the authority to control
all  substantial  decisions  of such  trust,  (or,  to the  extent  provided  in

is subject to the Employee  Retirement  Income  Security Act of 1974, as amended
("ERISA"),  Section 4975 of the Code, or any essentially similar Federal,  State
or local law (a "Similar Law") (each, a "Plan"), nor (b) a collective investment
fund in which such Plans are  invested,  an  insurance  company  using assets of
separate  accounts or general  accounts  which include assets of Plans (or which
are deemed  pursuant to ERISA or any Similar Law to include  assets of Plans) or
other  Person  acting on behalf of any such Plan or using the assets of any such
Plan,  other than an insurance  company using the assets of its general  account
under  circumstances  whereby such purchase and the  subsequent  holding of such
Certificate  by such  insurance  company  would  not  constitute  or result in a
prohibited  transaction  within  the  meaning  of  Section  406 or 407 or ERISA,
Section 4975 of the Code,  or a materially  similar  characterization  under any
Similar Law; and

     2. The Purchaser  understands that if the Purchaser is a Person referred to
in  1(a)  or  1(b)  above,  except  in the  case  of the  Class  R or  Class  LR
Certificate, which may not be transferred unless the transferee represents it is
not such a Person,  such Purchaser is required to provide to the Depositor,  the
Trustee and the Certificate Registrar an Opinion of Counsel which establishes to
the  satisfaction of the Depositor,  the Trustee and the  Certificate  Registrar
that the purchase or holding of the  Certificates by or on behalf of a Plan will
not result in the assets of the Trust Fund being deemed to be "plan  assets" and
subject  to the  fiduciary  responsibility  provisions  of ERISA and the Code or
Similar  Law,  and will not  constitute  or result in a  prohibited  transaction
within the meaning of Section 406 or Section 407 of ERISA or Section 4975 of the
Code,  and will not  subject the  Servicer,  the  Depositor,  the Trustee or the
Certificate  Registrar to any obligation or liability (including  obligations or
liabilities  under ERISA or Section 4975 of the Code),  which Opinion of Counsel
shall not be at the expense of the Servicer,  the Depositor,  the Trustee or the
Certificate Registrar.

     IN WITNESS WHEREOF,  the Purchaser hereby executes the ERISA Representation

                           FORM OF CUSTODIAL AGREEMENT

     THIS CUSTODIAL AGREEMENT, dated as of [ ] by and among [NAME OF CUSTODIAN],
as  Custodian  (the  "Custodian"),  AMRESCO  Services,  L.P.,  as servicer  (the
"Servicer"),  CRIIMI MAE Services Limited Partnership,  as special servicer (the
"Special Servicer"), and LaSalle National Bank, as Trustee (the "Trustee").


                              W I T N E S S E T H :

     WHEREAS, the Servicer,  the Special Servicer and the Trustee are parties to
a Pooling and Servicing Agreement (the "Pooling and Servicing Agreement"), dated
as of March 30, 1998, among Nomura Asset Securities  Corporation,  as Depositor,
the  Servicer,  the Special  Servicer,  the  Trustee and ABN AMRO Bank N.V.,  as
Fiscal  Agent,  relating  to Nomura  Asset  Securities  Corporation,  Commercial
Mortgage Pass-Through  Certificates,  Series 1998-D6 (capitalized terms used but
not  defined  herein  having the  meaning  assigned  thereto in the  Pooling and
Servicing Agreement);

     WHEREAS,  the parties hereto desire the Custodian to take possession of the
documents specified in Section 2.01 of the Pooling and Servicing  Agreement,  as
custodian for the Trustee, in accordance with the terms hereof;

     NOW,  THEREFORE,   in  consideration  of  the  mutual  undertakings  herein
expressed, the parties hereto hereby agree as follows:

     1. The Trustee  hereby  certifies  that it has caused to be  delivered  and
released to the Custodian and the Custodian hereby  acknowledges  receipt of the
documents  specified  in Section  2.01 of the  Pooling and  Servicing  Agreement
pertaining  to  each of the  Mortgage  Loans  identified  in the  Mortgage  Loan
Schedule attached to the Pooling and Servicing Agreement as Exhibit B. From time
to time,  the  Servicer  shall  forward  to the  Custodian  additional  original
documents  evidencing an assumption or  modification of a Mortgage Loan approved
by the Servicer.  All Mortgage Loan  documents  held by the Custodian as to each
Mortgage  Loan are referred to herein as the  "Custodian's  Mortgage  File." The
Custodian  hereby agrees to review each of the  Custodian's  Mortgage  Files and
perform such other  obligations  of the  Custodian as such  obligations  are set
forth in the Pooling and Servicing Agreement (including Section 2.02 thereof).

     2. With respect to each Note,  each Mortgage,  each  Assignment of Mortgage
and each other document  constituting  each  Custodian's  Mortgage File which is
delivered to the Custodian or which at any time comes into the possession of the
Custodian,  the Custodian is exclusively the custodian for and the bailee of the
Trustee or the  Servicer.  The Custodian  shall hold all documents  constituting
each Custodian's  Mortgage File received by it for the exclusive use and benefit
of the Trustee,  and shall make disposition  thereof only in accordance with the
instructions  furnished by the  Servicer.  The  Custodian  shall  segregate  and
maintain  continuous  custody  of all  documents  constituting  the  Custodian's
Mortgage File received in secure and fire  resistant  facilities  located in the
State of __________ in accordance with customary  standards for such custody. In
the event the  Custodian  discovers  any defect with respect to any  Custodian's
Mortgage File, the Custodian shall give written  specification of such defect to
the Servicer and the Trustee.

     3. From time to time and as appropriate for the foreclosure or servicing of
any of the  Mortgage  Loans,  the  Custodian  is hereby  directed,  upon written
request and receipt from the Servicer (a copy of which shall be forwarded to the
Trustee),  to release to the Servicer the related  Custodian's  Mortgage File or
the  documents  set forth in such  receipt to the  Servicer.  All  documents  so
released  to the  Servicer  shall be held by it in trust for the  benefit of the
Trustee.  The Servicer  shall return to the Custodian the  Custodian's  Mortgage
File or such documents when the Servicer's need therefor in connection with such
foreclosure  or servicing no longer  exists,  unless the Mortgage  Loan shall be
liquidated,  in which case, upon receipt of a certification  to this effect from
the Servicer to the Custodian,  the Servicer's  receipt shall be released by the
Custodian to the Servicer.

     4. Upon the  purchase  of any  Mortgage  Loan  pursuant to the terms of the
Pooling and Servicing Agreement or the payment in full of any Mortgage Loan, and
upon receipt by the Custodian of the Servicer's request for release, receipt and
certification  (which certification shall include a statement to the effect that
all amounts  received in connection  with such payment or  repurchase  have been
credit to the  Collection  Account or  Distribution  Account as  provided in the
Pooling and Servicing  Agreement),  the  Custodian  shall  promptly  release the
related Custodian's Mortgage File to the Servicer.

     5. It is  understood  that the  Custodian  will  charge  such  fees for its
services under this Agreement as are set forth in a separate  agreement  between
the  Custodian  and the  Servicer,  the  payment  of  which,  together  with the
Custodian's expenses in connection therewith,  shall be solely the obligation of
the Servicer.

     6. The  Trustee  may upon 30 days  written  days  notice  (with copy to the
Servicer)  remove  and  discharge  the  Custodian  or  any  successor  Custodian
thereafter  appointed  from the  performance  of its duties under this Custodial
Agreement.  Simultaneously,  the Trustee shall appoint a successor  Custodian to
act on its behalf by  written  instrument,  one  original  counterpart  of which
instrument  shall be delivered to each Rating  Agency,  one copy to the Servicer
and one copy to the successor  Custodian.  In the event of any such removal, the
Custodian shall promptly transfer to the successor Custodian,  as directed,  all
Custodian's  Mortgage Files being administered  under this Custodial  Agreement.
Notwithstanding  the foregoing,  so long as AMRESCO Services,  L.P. is Servicer,
the Trustee shall not have a right to remove the Custodian.

     7. Upon reasonable  prior written notice to the Custodian,  the Trustee and
its agents, accountants,  attorneys and auditors will be permitted during normal
business hours to examine the Custodian's Mortgage Files, documents, records and
other papers in the possession of or under the control of the Custodian relating
to any or all of the Mortgage Loans.

     8. If the  Custodian is furnished  with written  notice from the Trustee or
the Servicer that the Pooling and Servicing  Agreement has been terminated as to
any or all of the Mortgage  Loans,  it shall upon written request of the Trustee
or the Servicer  release to such  persons as the Trustee or the  Servicer  shall
designate the Custodian's  Mortgage Files relating to such Mortgage Loans as the
Trustee or the Servicer  shall  request and shall  complete the  Assignments  of
Mortgage  and  endorse  the Notes only as, and if, the  Trustee or the  Servicer
shall request.  The person making such written request shall send notice of such
request to all other parties to the Pooling and Servicing Agreement.

     9. The Custodian  shall,  at its own expense,  maintain at all times during
the existence of this Custodial  Agreement and keep in full force and effect (a)
fidelity insurance,  (b) theft of documents insurance, (c) forgery insurance and
(d) errors and omissions insurance. All such insurance shall be in amounts, with
standard  coverage and subject to  deductibles,  as are  customary for insurance
typically  maintained  by banks which act as custodian  in similar  transactions
provided,  however, that so long as the Custodian is rated at least "AA" no such
insurance shall be required.

     10. This Custodial  Agreement may be executed  simultaneously in any number
of counterparts,  each of which  counterparts shall be deemed to be an original,
and such counterparts shall constitute and be one and the same instrument.

     11.  Within  10 days  of each  anniversary  of the  date of this  Custodial
Agreement, or upon the request of the Trustee or the Servicer at any other time,
the  Custodian  shall  provide to the Trustee and the Servicer a list of all the
Mortgage  Loans  for which  the  Custodian  holds a  Custodian's  Mortgage  File
pursuant to this Custodial Agreement.  Such list may be in the form of a copy of
the Mortgage  Loan  Schedule with manual  deletions to  specifically  denote any
Mortgage  Loans  paid  off,  liquidated  or  repurchased  since the date of this
Custodial Agreement.

     12. This Custodial Agreement shall be construed in accordance with the laws
of the  State of New York,  and the  obligations,  rights  and  remedies  of the
parties hereunder shall be determined in accordance with such laws.

     13. By execution of this Custodial  Agreement,  the Custodian warrants that
it currently does not hold and during the existence of this Custodial  Agreement
shall not hold any adverse  interest,  by way of security or  otherwise,  in any
Mortgage  Loan,  and hereby waives and releases any such  interest  which it may
have in any Mortgage Loan as of the date hereof.

     14. The  Custodian  may  terminate  its  obligations  under this  Custodial
Agreement upon at least 60 days notice to the Trustee and the Servicer, provided
that so long as CRIIMI MAE Services Limited Partnership is the Servicer, AMRESCO
Services,  L.P. will not resign from its duties hereunder.  In the event of such
termination,  the  Trustee  shall  appoint  a  successor  Custodian.  Upon  such
appointment,  the Custodian shall promptly transfer to the successor  Custodian,
as  directed,  all  Custodian's  Mortgage  Files being  administered  under this
Custodial Agreement.

     15. This  Custodial  Agreement  shall  terminate  upon the final payment or
other liquidation (or advance with respect thereto) of the last Mortgage Loan or
the  disposition  of all property  acquired upon  foreclosure or deed in lieu of
foreclosure of any Mortgage Loan, and the final  remittance of all funds due the
Certificateholders under the Pooling and Servicing Agreement. In such event, all
documents remaining in the Custodian's  Mortgage Files shall be forwarded to the
Trustee.

     16. All demands,  notices and communications  hereunder shall be in writing
and shall be deemed to have been duly given when received by the addressee.  Any
such  demand,  notice or  communication  hereunder  shall be deemed to have been
received on the date  delivered to or received at the premises of the  addressee
(as evidenced, in the case of registered or certified mail, by the date noted on
the return receipt).

     17. The Servicer shall indemnify,  defend,  and hold harmless the Custodian
for any actions taken by the Custodian at its written request.

such other  documents,  instruments and agreements as the Company or the Trustee
shall reasonably request.

     2.  Representations  and Warranties.  (a) The Seller hereby  represents and
warrants to the Company as of the Closing Date that:

       (i)    The Seller is a corporation  duly organized,  validly existing and
              in good standing under the laws of the State of Delaware with full
              power  and  authority  to  carry  on  its  business  as  presently
              conducted by it;

       (ii)   The  Seller  has  taken all  necessary  action  to  authorize  the
              execution,  delivery and  performance of this Agreement by it, and
              has the power and  authority to execute,  deliver and perform this
              Agreement and all the transactions contemplated hereby, including,
              but not limited to, the power and  authority  to sell,  assign and
              transfer the Mortgage Loans in accordance with this Agreement;

       (iii)  Assuming  the due  authorization,  execution  and delivery of this
              Agreement  by  the  Company,   this   Agreement  and  all  of  the
              obligations  of the  Seller  hereunder  are the  legal,  valid and
              binding obligations of the Seller,  enforceable in accordance with
              the terms of this  Agreement,  except as such  enforcement  may be
              limited by bankruptcy,  insolvency,  reorganization,  liquidation,
              receivership,  moratorium  or other laws  relating to or affecting
              creditors'  rights generally,  or by general  principles of equity
              (regardless  of whether such  enforceability  is  considered  in a
              proceeding in equity or at law);

       (iv)   The execution and delivery of this  Agreement and the  performance
              of its obligations  hereunder by the Seller does not conflict with
              any  provision  of any law or  regulation  to which the  Seller is
              subject,  or conflict with,  result in a breach of or constitute a
              default  under any of the terms,  conditions  or provisions of any
              agreement or instrument to which the Seller is a party or by which
              it is bound, or any order or decree  applicable to the Seller,  or
              result in the  creation  or  imposition  of any lien on any of the
              Seller's assets or property,  which would materially and adversely
              affect the  ability  of the  Seller to carry out the  transactions
              contemplated  by this  Agreement.  The  Seller  has  obtained  any
              consent,  approval,   authorization  or  order  of  any  court  or
              governmental  agency or body required for the execution,  delivery
              and performance by the Seller of this Agreement; and

       (v)    There is no action,  suit or proceeding pending against the Seller
              in any court or by or  before  any  other  governmental  agency or
              instrumentality  which would  materially and adversely  affect the
              ability  of the  Seller to carry out its  obligations  under  this
              Agreement  or have a  material  adverse  effect  on the  financial
              condition  of the  Seller or the  ability of the Seller to perform
              its obligations under this Agreement.

     (b) The Seller hereby represents and warrants with respect to each Mortgage
Loan that as of the date specified below or, if no such date is specified, as of
the Closing Date:

          (i)       Immediately  prior to the sale,  transfer and  assignment to
                    the Company,  each related Note and Mortgage was not subject
                    to an assignment  (other than to the Seller) or pledge,  and
                    the  Seller  had good and  marketable  title to, and was the
                    sole owner of, the Mortgage Loan;

          (ii)      The Seller has full right and authority to sell,  assign and
                    transfer  such  Mortgage  Loan  and  the  assignment  to the
                    Company constitutes a legal, valid and binding assignment of
                    such Mortgage;

          (iii)     The Seller is transferring such Mortgage Loan free and clear
                    of any and all liens, pledges, charges or security interests
                    of any nature  encumbering such Mortgage Loan subject to the
                    matters described in clause (xi) below;

          (iv)      Each related Note, Mortgage,  Assignment of Leases and Rents
                    (if any) and other  agreement  executed in  connection  with
                    such Mortgage Loan are legal, valid and binding  obligations
                    of the related  Borrower,  enforceable  in  accordance  with
                    their terms,  except as such  enforcement  may be limited by
                    bankruptcy, insolvency, reorganization,  moratorium or other
                    laws  affecting  the   enforcement   of  creditors'   rights
                    generally, or by general principles of equity (regardless of
                    whether such enforceability is considered in a proceeding in
                    equity or at law) and to the best of the Seller's knowledge,
                    there is no valid defense, counterclaim, right of rescission
                    or right of set-off or  abatement  available  to the related
                    Borrower  with  respect  to such  Note,  Mortgage  and other
                    agreements;

          (v)       Each related Assignment of Leases and Rents creates a valid,
                    collateral or first priority assignment of, or a valid first
                    priority  security  interest  in,  certain  rights under the
                    related  lease,  subject  only to a license  granted  to the
                    related  Borrower to exercise  certain rights and to perform
                    certain   obligations   of  the  lessor  under  such  lease,
                    including  the  right  to  operate  the  related   Mortgaged
                    Property; no person other than the related Borrower owns any
                    interest  in any  payments  due  under  such  lease  that is
                    superior  to or  of  equal  priority  with  the  mortgagee's
                    interest therein;

          (vi)      Each related  assignment  of Mortgage from the Seller to the
                    Company and any related Reassignment of Assignment of Leases
                    and Rents,  if any,  or  assignment  of any other  agreement
                    executed in  connection  with such Mortgage  Loan,  from the
                    Seller  to the  Company  constitutes  the  legal,  valid and
                    binding assignment from the Seller to the Company, except as
                    such  enforcement may be limited by bankruptcy,  insolvency,
                    reorganization,  liquidation,  receivership,  moratorium  or
                    other  laws  relating  to  or  affecting  creditors'  rights
                    generally, or by general principles of equity (regardless of
                    whether such enforceability is considered in a proceeding in
                    equity or at law);

          (vii)     Since  origination,  and except as set forth in the  related
                    Mortgage  File,  such  Mortgage  Loan has not  been  waived,
                    modified,  altered,  satisfied,  canceled,  subordinated  or
                    rescinded and, each related Mortgaged  Property has not been
                    released from the lien of the related Mortgage in any manner
                    which materially interferes with the security intended to be
                    provided by such Mortgage;

          (viii)    Each related Mortgage is a valid and enforceable  first lien
                    on  the  related  Mortgaged  Property,  and  such  Mortgaged
                    Property  (subject to the matters  described  in clause (xi)
                    below),   is  free   and   clear  of  any   mechanics'   and
                    materialmen's  liens  which are  prior to or equal  with the
                    lien of the related Mortgage, except those which are insured
                    against by a lender's title  insurance  policy (as described
                    below);

          (ix)      The  Seller has not taken any  action  that would  cause the
                    representations and warranties made by each related Borrower
                    in the Mortgage Loan not to be true;

          (x)       The Seller has no  knowledge  that the  representations  and
                    warranties  made by each related  Borrower in such  Mortgage
                    Loan are not true in any material respect;

          (xi)      Except  with  respect to the  Mortgage  Loan  secured by the
                    Mortgaged  Property  known as the  Westin  Casuarina  Resort
                    Property,  which has a  Certificate  of Title from the Grand
                    Cayman Island government,  the lien of each related Mortgage
                    is insured by an ALTA lender's title insurance  policy (or a
                    binding commitment  therefor),  or its equivalent as adopted
                    in the  applicable  jurisdiction,  insuring the Seller,  its
                    successors and assigns, or the holder of the related Note as
                    to a valid and first  priority  lien of the  Mortgage  in at
                    least the original principal amount of such Mortgage Loan or
                    Allocated Loan Amount of the related Mortgaged  Property (as
                    set forth on the Mortgage Loan Schedule  which is an exhibit
                    to the Pooling and Servicing Agreement), subject only to (a)
                    the lien of current real property taxes, ground rents, water
                    charges,  sewer  rents  and  assessments  not  yet  due  and
                    payable, (b) covenants, conditions and restrictions,  rights
                    of way,  easements and other matters of public record,  none
                    of  which,  individually  or in  the  aggregate,  materially
                    interferes   with  the  current  use  or  operation  of  the
                    Mortgaged  Property or the security  intended to be provided
                    by such Mortgage or with the  Borrower's  ability to pay its
                    obligations  when  they  become  due  or  the  value  of the
                    Mortgaged  Property  and (c)  the  exceptions  (general  and
                    specific)   set  forth  in  such  policy,   none  of  which,
                    individually or in the aggregate, materially interferes with
                    the  security  intended to be  provided by such  Mortgage or
                    with the related  Borrower's  ability to pay its obligations
                    when they become due or the value,  use or  operation of the
                    Mortgaged Property;  the Seller or its successors or assigns
                    is the sole named  insured of such  policy;  such  policy is
                    assignable  to the  Company  without  the  consent of or any
                    notification to the insurer, and is in full force and effect
                    upon the  consummation of the  transactions  contemplated by
                    this  Agreement;  no claims have been made under such policy
                    and the Seller has not done  anything,  by act or  omission,
                    and the Seller has no knowledge  of any matter,  which would
                    impair or  diminish  the  coverage  of such  policy;  to the
                    extent  required by applicable law, the insurer issuing such
                    policy is  qualified to do business in the  jurisdiction  in
                    which the related Mortgaged Properties are located;

          (xii)     The proceeds of such Mortgage Loan have been fully disbursed
                    and there is no requirement for future  advances  thereunder
                    and the  Seller  covenants  that it will not make any future
                    advances under the Mortgage Loan to the related Borrower;

          (xiii)    Each  related  Mortgaged  Property  is free of any  material
                    damage that would affect  materially and adversely the value
                    of such Mortgaged Property as security for the Mortgage Loan
                    and there is no proceeding  pending for the total or partial
                    condemnation of such Mortgaged Property;

          (xiv)     Each of the related Borrowers (and, if the related Mortgaged
                    Property  is  secured  by a  senior  housing  or  healthcare
                    facility,  each of the  operators  of such  facility)  is in
                    possession  of all  material  licenses,  permits  and  other
                    authorizations necessary and required by all applicable laws
                    for the  conduct  of its  business  and all  such  licenses,
                    permits and  authorizations  are valid and in full force and
                    effect, and if a related Mortgaged Property is improved by a
                    healthcare facility, the most recent inspection or survey by
                    governmental  authorities having  jurisdiction in connection
                    with such licenses,  permits and authorizations did not cite
                    such Mortgaged Property for material violations (which shall
                    include only "Level A" violations or the equivalent,  in the
                    case of  skilled  nursing  facilities,  that  have  not been
                    cured); and if a related Mortgaged Property is improved by a
                    hotel,   the  most  recent   inspection  or  review  by  the
                    franchisor, if any, did not cite such Mortgaged Property for
                    material violations of the related franchise agreement which
                    have not been cured;

          (xv)      The Seller or, to the best of Seller's knowledge, Bloomfield

                    passu loan from the Seller secured by the related  Mortgaged
                    Property  (which  other  loan is not  included  in the Trust
                    Fund), such Mortgage Loan is a whole loan and no other party
                    holds an interest in the Mortgage Loan;

          (xviii)  (A)The Mortgage Rate (exclusive of any default interest, late
                    charge or yield  maintenance  charge) of such  Mortgage Loan

                    from,  applicable  state or federal  laws,  regulations  and
                    other  requirements  pertaining to usury;  any and all other
                    requirements of any federal, state or local laws, including,

                    applicable  to such Mortgage Loan have been complied with as
                    of the date of origination of such Mortgage Loan and (B) the

                    Bloomfield  during the origination  process of such Mortgage
                    Loan and the  origination,  servicing and collection of each
                    Mortgage Loan is in all respects  legal,  proper and prudent
                    in accordance with customary industry standards;

          (xx)      All taxes and  governmental  assessments  that  prior to the
                    Closing  Date  became  due and  owing in  respect  of,  each

          (xxi)     All escrow  deposits and payments  required  pursuant to the
                    Mortgage Loans are in the possession,  or under the control,
                    of the Seller or its agent and there are no  deficiencies in
                    connection  therewith and all such escrows and deposits have
                    been conveyed by the Seller to the Company and identified as
                    such with appropriate detail;

          (xxii)    To the  extent  required  under  applicable  law,  as of the
                    Cut-off Date,  the Seller was  authorized to transact and do
                    business in the jurisdiction in which each related Mortgaged
                    Property  is located at all times when it held the  Mortgage
                    Loan;

          (xxiii)   (A)Each related Mortgaged Property  is insured by a fire and
                    extended  perils  insurance  policy,  issued  by an  insurer
                    meeting the requirements  under the related Mortgage Loan in
                    an amount not less than the replacement  cost and the amount
                    necessary  to  avoid  the  operation  of  any   co-insurance
                    provisions  with respect to the Mortgaged  Property,  except
                    the CarMax  Credit  Lease Loans and the Circuit  City Credit
                    Lease Loans,  under which the related  Mortgaged  Properties
                    are  self-insured  by the related Credit Tenant,  and except
                    with  respect  to  certain  portions  of  certain  Mortgaged

                    portion of such Mortgaged Property;

                    (B)  Each related Mortgaged  Property is covered by business

                         interruptions)   (except   the   Mortgaged   Properties
                         securing the CarMax  Credit Lease Loans and the Circuit
                         City  Credit  Lease  Loans  which do not have  business
                         interruption  insurance) and each Mortgaged Property is
                         covered by comprehensive general liability insurance in
                         amounts generally required by institutional lenders for
                         similar properties;

                    (C)  All premiums on any insurance  policies  required to be
                         paid as of the date hereof have been paid;

                    (D)  The  insurance  policies  require  prior  notice to the
                         insured of  termination  or  cancellation,  and no such
                         notice has been received; and

                    (E)  Each related  Mortgage or Loan Agreement  obligates the
                         related Borrower to maintain all such insurance and, at
                         such  Borrower's  failure  to  do  so,  authorizes  the
                         mortgagee to maintain such  insurance at the Borrower's
                         cost and  expense  and to seek  reimbursement  therefor
                         from such Borrower;

          (xxiv)    There  is  no  default,   breach,   violation  or  event  of
                    acceleration  existing  under the  related  Mortgage  or the
                    related Note and, to the Seller's knowledge, no event which,
                    with the passage of time or with  notice and the  expiration
                    of any grace or cure  period,  would and does  constitute  a
                    default, breach, violation or event of acceleration;

          (xxv)     Such Mortgage  Loan has not been 30 days or more  delinquent
                    since  origination  and  as of  the  Cut-off  Date  was  not
                    delinquent;

          (xxvi)    Each related  Mortgage  contains  customary and  enforceable
                    provisions  such as to render the rights and remedies of the
                    holder  thereof  adequate  for the  realization  against the
                    Mortgaged   Property  of  the  benefits  of  the   security,
                    including   realization   by  judicial  or,  if  applicable,
                    non-judicial   foreclosure,   and  there  is  no   exemption
                    available to the Borrower  which would  interfere  with such
                    right to foreclose.  To the best of the Seller's  knowledge,
                    no Borrower is a debtor in a state or federal  bankruptcy or
                    insolvency preceding;

          (xxvii)   In each  related  Mortgage or Loan  Agreement  (except  with
                    respect  to the  Mortgage  Loan known as SL  Hillside),  the
                    related Borrower represents and warrants that, except as set
                    forth in certain  environmental  reports or other  documents
                    previously  provided to the Rating  Agencies and to the best
                    of its  knowledge,  it has not used,  caused or permitted to
                    exist  and  will not use,  cause or  permit  to exist on the
                    related  Mortgaged  Property any Hazardous  Materials in any
                    manner  which  violates   federal,   state  or  local  laws,
                    ordinances,  regulations,  orders,  directives  or  policies
                    governing  the  use,  storage,  treatment,   transportation,
                    manufacture, refinement, handling, production or disposal of
                    Hazardous   Materials;   the  related   Borrower  agrees  to
                    indemnify,  defend and hold the mortgagee and its successors
                    and  assigns  harmless  from and against any and all losses,
                    liabilities,  damages, injuries, penalties, fines, expenses,
                    and claims of any kind whatsoever (including attorneys' fees
                    and  costs)  paid,  incurred  or  suffered  by, or  asserted
                    against,  any such party  resulting from a breach of certain
                    representations,   warranties  or  covenants  given  by  the
                    Borrower  in  such  Mortgage  or Loan  Agreement.  A Phase I
                    environmental   report   was   conducted   by  a   reputable
                    environmental  engineer  in  connection  with such  Mortgage
                    Loan,   which   report  does  not   indicate   any  material
                    non-compliance or material existence of Hazardous Materials,
                    except as  disclosed  in the  Prospectus  Supplement  to the
                    Prospectus,   each  dated  March  27,   1998,   under  "Risk
                    Factors--The     Mortgage      Loans--Environmental      Law
                    Considerations." To the best of the Seller's knowledge, each
                    related  Mortgaged  Property,  except  as  disclosed  in the
                    Prospectus,  is in material  compliance  with all applicable
                    federal,  state and local laws  pertaining to  environmental
                    hazards, and to the best of Seller's knowledge, no notice of
                    violation  of such laws has been issued by any  governmental
                    agency or  authority;  the  Seller  has not taken any action
                    which would cause the related  Mortgaged  Property not to be
                    in  compliance  with  all  federal,  state  and  local  laws
                    pertaining to environmental hazards;

          (xxviii)  Each related Mortgage or Loan Agreement contains  provisions
                    for the  acceleration of the payment of the unpaid principal
                    balance of such Mortgage Loan if, without complying with the
                    requirements  of the Mortgage or Loan Agreement or obtaining
                    the  prior   written   consent  of  the   Mortgagee  or  the
                    satisfaction of certain  conditions,  the related  Mortgaged
                    Property, or any interest therein, is directly or indirectly
                    transferred  or  sold,  or  encumbered  in  connection  with
                    subordinate  financing and each related  Mortgage  prohibits
                    the pledge or encumbrance of the Mortgaged  Property without
                    the consent of the holder of the Mortgage Loan;

          (xxix)    (1) The Mortgage Loan is directly secured by a Mortgage on a
                    commercial property or multifamily residential property, and
                    (2) the fair market value of such real property was at least
                    equal to 80% of the  principal  amount of the Mortgage  Loan
                    (a) at  origination  (or  if  the  Mortgage  Loan  has  been
                    modified  in a manner  that  constituted  a deemed  exchange
                    under  Section  1001 of the Code at a time when the Mortgage
                    Loan was not in default or default with respect  thereto was
                    not  reasonably  foreseeable,  the  date  of the  last  such
                    modification) or (b) at the Closing Date;  provided that the
                    fair market value of the real  property  interest must first
                    be  reduced  by (A)  the  amount  of any  lien  on the  real
                    property  interest  that  is  senior  to the  Mortgage  Loan
                    (unless  such senior lien also secures a Mortgage  Loan,  in
                    which event the  computation  described in (a) and (b) shall
                    be  made on an  aggregated  basis)  and (B) a  proportionate
                    amount of any lien that is in parity with the Mortgage  Loan
                    (unless  such  other lien  secures a  Mortgage  Loan that is
                    cross-collateralized with such Mortgage Loan, in which event
                    the computation described in (a) and (b) shall be made on an
                    aggregate   basis).   All  improvements   included  for  MAI
                    appraisals   are  within  the   boundaries  of  the  related
                    Mortgaged Property;

          (xxx)     Each Mortgage Loan constitutes a "qualified mortgage" within
                    the meaning of Section  860G(a)(3)  of the Code (but without
                    regard to the rule in  Treasury  Regulations  1.860G-2(f)(2)
                    that treats a defective  obligation as a qualified mortgage,
                    or any substantially similar successor provision);

          (xxxi)    The  mortgage  loan  schedule  which  is an  exhibit  to the
                    Pooling and Servicing  Agreement is complete and accurate in
                    all respects;

          (xxxii)   Except with respect to the Mortgaged  Properties known as SL
                    Hillside  (in  which   approximately  2-3%  of  the  related
                    Mortgaged  Property  is used  for a  purpose  which is not a
                    conforming use or a legal  non-conforming use) and Reservoir
                    Nursing  Home  (which  is  in  violation  of  certain  state
                    requirements   relating   to  the  number  of  beds  at  the
                    facility),  each Mortgaged Property is in compliance, in all
                    material   respects,   with  all  applicable  laws,   zoning
                    ordinances,  rules, covenants and restrictions affecting the
                    construction, occupancy, use and operation of such Mortgaged
                    Property.   All   inspections,   licenses  and  certificates
                    required,    including   certificates   of   occupancy   (if
                    applicable),   whether  by  law,  ordinance,  regulation  or
                    insurance  standards to be made or issued with regard to the
                    Mortgaged Property, have been obtained and are in full force
                    and effect;

          (xxxiii)  (A) Except as disclosed on Exhibit A attached  hereto,  each
                    Borrower is an entity whose organizational documents provide
                    that it is,  and at  least so long as the  Mortgage  Loan is
                    outstanding  will continue to be, a  single-purpose  entity.
                    (For this  purpose,  "single-purpose  entity"  shall  mean a
                    person,  other  than  an  individual,  which  is  formed  or
                    organized  solely for the purpose of owning and  operating a
                    single  property  (other than the borrower under the Andover
                    Park Mortgage Loan which owns an undeveloped parcel adjacent
                    to the related Mortgaged  Property),  does not engage in any
                    business unrelated to such property and its financing,  does
                    not have any assets other than those related to its interest
                    in the property or its financing,  or any indebtedness other
                    than as permitted by the related  Mortgage or the other Loan
                    Documents,  has its  own  books  and  records  and  accounts
                    separate and apart from any other  person,  and holds itself
                    out as being a legal  entity,  separate  and apart  from any
                    other person);

                    (B)  Except  with  respect  to the six  loans to  affiliated
                         borrowers  (including the Coach House Loan)  identified
                         on Exhibit B hereto as borrower affiliation number 3, a
                         non-consolidation   opinion  was   obtained   for  each
                         Borrower or group of affiliated  Borrowers in which the
                         Cut-off Date Principal  Balance of the Mortgage Loan or

          (xxxiv)   With respect to any Mortgage  Loan where a material  portion
                    of the estate of the related Borrower therein is a leasehold
                    estate  and the fee  interest  of the  ground  lessor is not
                    subject and subordinate to the related Mortgage,  the Seller
                    represents and warrants that:

                    (A)  The ground lease or a memorandum  regarding it has been
                         duly recorded. The ground lease permits the interest of
                         the lessee to be encumbered by the related Mortgage and
                         does  not  restrict  the use of the  related  Mortgaged
                         Property by such lessee, its successors or assigns in a
                         manner  that  would   adversely   affect  the  security
                         provided  by the  related  Mortgage.  There has been no
                         material change in the terms of such ground lease since
                         its recordation,  except by written instruments, all of
                         which are included in the related Mortgage File;

                    (B)  Except  with  respect  to the  ground  leases  for  the
                         Mortgage  Loans  known  as  Westin  Casuarina   Resort,
                         Bristol I-New Orleans French Quarter and Monterey Plaza
                         Hotel Property,  the lessor under such ground lease has
                         agreed in writing and included in the related  Mortgage
                         File  that  the  ground   lease  may  not  be  amended,
                         modified,  canceled  or  terminated  without  the prior
                         written  consent  of the  mortgagee  and  that any such
                         action  without  such  consent  is not  binding  on the
                         mortgagee, its successors or assigns;

                    (C)  Except with respect to the Mortgaged  Property securing
                         the FAC Realty  Loan,  known as Boaz,  and except  with
                         respect to the  Headquarters  Plaza Loan, each of which
                         related  ground lease expires four years  following the
                         maturity  date of such Mortgage Loan (and both of which
                         have loan documents  that require the related  borrower
                         to purchase  such  Mortgaged  Property,  in the case of
                         Boaz,  the Purchase  Price has been  escrowed  with the
                         Trustee  and in the  case  of  Headquarters  Plaza  the
                         Purchase  Price is  $1.00),  the  ground  lease  has an
                         original  term (or an  original  term  plus one or more
                         optional renewal terms, which, under all circumstances,
                         may be  exercised,  and  will  be  enforceable,  by the
                         mortgagee)  that  extends not less than 10 years beyond
                         the stated maturity of the related Mortgage Loan;

                    (D)  The ground lease is prior to any mortgage or other lien
                         upon the related fee  interest and the landlord has not
                         entered  into an agreement  to  subordinate  the ground
                         lease to future mortgages or liens on the fee interest.

                    (E)  Except with  respect to the ground  leases for Stanford
                         Park  Hotel,  the  ground  lease is  assignable  to the
                         mortgagee  under the  leasehold  estate and its assigns
                         without the consent of the lessor thereunder.

                    (F)  As of the date of hereof,  the ground  lease is in full
                         force and effect and no default  has  occurred,  nor is
                         there any existing condition which, but for the passage
                         of time or giving of notice,  would result in a default
                         under the terms of the ground lease;

                    (G)  Except with respect to the Mortgaged  Property known as
                         the Westin Casuarina Resort Property,  the ground lease
                         or  ancillary  agreement  between  the  lessor  and the
                         lessee  requires  the  lessor  to  give  notice  of any
                         default by the lessee to the mortgagee;

                    (H)  Except with respect to the Mortgaged  Property known as
                         the Westin Casuarina  Resort  Property,  a mortgagee is
                         permitted a reasonable  opportunity  (including,  where
                         necessary,  sufficient  time to gain  possession of the
                         interest of the lessee under the ground  lease  through
                         legal  proceedings,  or to take other action so long as
                         the  mortgagee is  proceeding  diligently)  to cure any
                         default  under the ground lease which is curable  after
                         the receipt of notice of any default  before the lessor
                         may  terminate  the  ground  lease.  All  rights of the
                         mortgagee  under  the  ground  lease  and  the  related
                         Mortgage  (insofar  as it relates to the ground  lease)
                         may be exercised by or on behalf of the mortgagee;

                    (I)  The ground  lease does not impose any  restrictions  on
                         subletting   that  would  be  viewed  as   commercially
                         unreasonable by an institutional  investor.  The lessor
                         is not permitted to disturb the possession, interest or
                         quiet  enjoyment of any  subtenant of the lessee in the
                         relevant  portion of the Mortgaged  Property subject to
                         the  ground  lease for any  reason,  or in any  manner,
                         which would adversely  affect the security  provided by
                         the related Mortgage;

                    (J)  The ground lease  provides  that any related  insurance
                         proceeds or  condemnation  award (other than in respect
                         of a total or substantially  total loss or taking) will
                         be applied  either to the repair or  restoration of all
                         or part of the  related  Mortgaged  Property  with  the
                         mortgagee or a trustee appointed by it having the right
                         to  hold  and  disburse  such  proceeds  as  repair  or
                         restoration  progresses  (except  with  respect  to the
                         ground  lease for the Value City  Credit  Lease  Loans,
                         known as 3080/3232  Alum Creek Drive and One Mall Road,
                         under  which  the  related  Credit  Tenant  may,  under
                         certain  circumstances,  hold  and  disburse  insurance
                         proceeds),  or,  if  permitted  by the  related  ground
                         lease,  to the  payment  of the  outstanding  principal
                         balance of the Mortgage Loan, together with any accrued
                         interest,  except  that  in the  case  of  condemnation
                         awards,  the ground  lessor is entitled to an amount of
                         such  award   generally  based  on  the  value  of  the
                         unimproved land taken;

                    (K)  Except  with  respect  to the  ground  leases  for  the
                         Burnham  Pacific-Golden State Discovery Plaza Property,
                         the  Bristol  I-Holiday   Inn-Houston   Medical  Center
                         Property and the Bristol I-New Orleans  French  Quarter
                         Property (under each of which the proceeds must be used
                         to rebuild the related Mortgaged  Property),  under the
                         terms of the ground lease and the related Mortgage, any
                         related insurance  proceeds,  or condemnation  award in
                         respect  of a  total  or  substantially  total  loss or
                         taking  of  the  related  Mortgaged  Property  will  be
                         applied  first  to  the  payment  of  the   outstanding
                         principal  balance of the Mortgage Loan,  together with
                         any  accrued   interest   (except  where   contrary  to
                         applicable law or in cases where a different allocation
                         would not be viewed as commercially unreasonable by any
                         institutional   investor,   taking  into   account  the
                         relative  duration of the ground  lease and the related
                         Mortgage  and the  ratio  of the  market  value  of the
                         related Mortgage property to the outstanding  principal
                         balance  of such  Mortgage  Loan.  Until the  principal
                         balance  and  accrued  interest  rate are paid in full,
                         neither  the  lessee  nor the  lessor  under the ground
                         lease will have the option to  terminate  or modify the
                         ground  lease  without  prior  written  consent  of the
                         mortgagee  as a  result  of  any  casualty  or  partial
                         condemnation, except to provide for an abatement of the
                         rent;

                    (L)  Except  with  respect  to the  ground  leases  for  the
                         Mortgaged  Properties  know as  Bristol  I-New  Orleans

                         Park,  MHP,  the ground  lease  requires  the lessor to
                         enter  into a new  lease  upon the  termination  of the
                         ground lease or upon rejection of the ground lease in a
                         bankruptcy proceeding; and

                    (M)  The rent due under  the  ground  lease  for the  Westin
                         Casuarina  Resort  Property has been fully paid for the
                         full term of the lease.

                    earthquake,  windstorm or flood insurance, as of the Cut-off
                    Date, such insurance is required to be maintained  until the
                    principal  balance of the related  Mortgage  Loan is paid in
                    full;

          (xxxvi)   With     respect    to     Mortgage     Loans    that    are

                    in  the  related  Borrower  or the  direct  parent  of  such
                    Borrower),  neither the Seller nor any affiliate thereof has
                    any obligation or right to make any capital  contribution to

                    Borrower under a Mortgage Loan is an affiliate of a Borrower
                    under any other Mortgage Loan;

          (xxxix)   After receipt of the Purchase Price, the Seller has no right
                    of set-off  with  respect to the  transfer  of the  Mortgage
                    Loans to the Company;

          (xl)      With respect to each Mortgage Loan originated by Bloomfield:

                    (A)  Such Mortgage Loan was  underwritten in accordance with
                         standards  established by the Seller, using application
                         forms and  related  credit  documents  approved  by the

                         agreed to fund such loan;

                    (C)  The  closing  documents  for such  Mortgage  Loan  were

                         reason of any damage to or  destruction  of any portion

                         interference of the Credit  Tenant's use,  occupancy or
                         enjoyment of the leased  property,  provided,  however,
                         that the Credit Lease may permit a lease termination in
                         any such event if notice by the  Credit  Tenant of such
                         termination is accompanied by the exercise of an option
                         to purchase  the  Mortgaged  Property  for at least the
                         principal  balance of the  Mortgage  Loans plus accrued
                         interest;

                    (C)  In the  event  that the  related  Credit  Lease  may be
                         terminated   upon  the  occurrence  of  a  casualty  or
                         condemnation, such Credit Lease Loan has the benefit of
                         a noncancelable  Lease Enhancement Policy for which the
                         premium has been paid in full;

                    (D)  The  Borrower  does not have any  monetary  obligations
                         under  the  Lease,   and  every   monetary   obligation
                         associated  with  managing,   owning,   developing  and
                         operating  the  leased  property  (including,  but  not
                         limited to, the costs associated with utilities, taxes,
                         insurance,  ground rents,  payments  under any easement

                         maintenance and repairs) is an obligation of the Credit
                         Tenant;

                    (E)  The Borrower does not have any  continuing  nonmonetary
                         obligations  under the Credit Lease, the performance of
                         which would involve a material  expenditure of funds or
                         the  non-performance  of which would entitle the Credit
                         Tenant to terminate the related Credit Lease;

                    (F)  The Borrower has not made any false  representation  or
                         warranty  under the Credit  Lease that would impose any
                         material  monetary  obligation upon the Borrower or any
                         Landlord  or result in the  termination  of the  Credit
                         Lease;

                    (G)  Except with  respect to the Best Buy Credit  Lease Loan
                         and the Eckerd  Credit  Lease Loan,  the Credit  Tenant
                         cannot terminate the Credit Lease for any reason, prior
                         to the  payment  in full  of or the  payment  of  funds
                         sufficient to pay in full (i) the principal  balance of
                         the Mortgage Loan, (ii) all accrued and unpaid interest
                         on the Mortgage  Loan, and (iii) any other sums due and
                         payable  under the  Mortgage  Loan,  as of the  related
                         termination  date,  except for a default by the related
                         Borrower under the Credit Lease;

                    (H)  In the event the Credit  Tenant  assigns or sublets the
                         leased  property,  the Credit Tenant remains  primarily
                         obligated under the Credit Lease;

                    (I)  The Credit  Tenant has agreed to indemnify  the related
                         Borrower  from any  claims of any  nature  arising as a
                         result of any hazardous  material  affecting the leased
                         property  caused by the Credit Tenant and arising after
                         commencement of the Credit Lease;

                    (J)  to the Seller's  knowledge,  each Credit Lease contains
                         customary and enforceable  provisions  which render the
                         rights and remedies of the lessor  thereunder  adequate
                         for the  enforcement  and  satisfaction of the lessor's
                         rights thereunder;

                         documents,  as of the closing date of each Credit Lease
                         Loan

                            (1)    each  Credit  Lease  was in  full  force  and
                                   effect, and no default by the Borrower or the
                                   Tenant has occurred  under the Credit  Lease,
                                   nor is there any  existing  condition  which,
                                   but for the  passage of time or the giving of
                                   notice  or both,  would  result  in a default
                                   under the terms of the Credit Lease;

                            (2)    none of the terms of the  Credit  Lease  have
                                   been impaired, waived, altered or modified in
                                   any  respect  (except  as  described  in  the
                                   related tenant estoppel) and the Credit Lease
                                   Loan provides  that the related  Credit Lease
                                   cannot be modified without the consent of the
                                   Seller;

                            (3)    no Credit  Tenant has been  released in whole
                                   or in part,  from its  obligations  under the
                                   Credit Lease;

                            (4)    there  is no  current  right  of  rescission,
                                   offset,  abatement,  diminution,  defense  or
                                   counterclaim  to any Credit  Lease,  nor will
                                   the  operation  of any of  the  terms  of the
                                   Credit Leases,  or the exercise of any rights
                                   thereunder,    render   the   Credit    Lease
                                   unenforceable  (in  whole  or  in  part),  or
                                   subject to any right of  rescission,  offset,
                                   abatement,     diminution,     defense     or
                                   counterclaim  and no such  right or claim has
                                   been asserted with respect thereto; and

                            (5)    each  Credit  Lease  has a term  ending on or
                                   after  the  final  maturity  of  the  related
                                   Credit  Lease Loan and except with respect to

                                   a Balloon  Payment at its maturity (and which
                                   has in  effect a  Residual  Value  Policy  to
                                   cover any difference), each Credit Lease Loan
                                   is   fully-amortizing   from  rent   payments
                                   received during the term of the Credit Lease;

                    (L)  to the Mortgage Loan Seller's knowledge,  the Mortgaged
                         Property  is not  subject  to any lease  other than the
                         related  Credit  Lease,  except  with  respect  to  the
                         Mortgaged  Properties  securing  the Value City  Credit

                         tenant whose rent was not used in  underwriting  of the
                         Credit  Lease  Loan,  no  Person  has  any   possessory
                         interest  in,  or  right  to  occupy,   the   Mortgaged
                         Property,  except  under and  pursuant  to such  Credit
                         Lease and the Credit  Tenant  under the related  Credit
                         Lease, or its wholly-owned subsidiary,  is in occupancy

                    (M)  each  Credit  Tenant has agreed to notify the Seller of
                         any event of default under the related Credit Lease and
                         to  provide  the  Seller  with  additional  time and an
                         opportunity to cure;

                    (N)  each Credit  Tenant under a Credit Lease is required to
                         make all rental payments  directly to the Seller (or an
                         account  controlled  by  Seller),  its  successors  and
                         assigns;

                    (O)  each Credit Lease Loan provides that the related Credit
                         Lease  cannot be  modified  without  the consent of the
                         Seller thereunder;

                    (P)  the  credit  lease  assignment  creates  a valid  first
                         priority security interest in favor of the Seller,  its
                         successors  and  assigns,  in rights  under the  Credit
                         Lease,  including the right to monthly  lease  payments
                         and, to the extent  payable  under each  Credit  Lease,

                    (Q)  no person owns any  interest in any  payments due under
                         such Credit Lease other than the Borrower;

                    (R)  the Credit Lease is subordinate in right to the related
                         Mortgage;

                    (S)  in the event  the  Trustee  acquires  title to a Credit
                         Lease  Property  by   foreclosure  or  otherwise,   the
                         Borrower's  interest  under the related Credit Lease is
                         freely assignable by the Trustee and its successors and
                         assigns to any person without the consent of the Credit
                         Tenant, and in the event the Borrower's  interest is so
                         assigned,  the  Credit  Tenant  will  be  obligated  to
                         recognize  the  assignee  as lessor  under such  Credit
                         Lease;

                         guaranty  from the  rated  parent or  affiliate  of the
                         Credit  Tenant,  (i) such guaranty is legal,  valid and

                         (iv) the  guaranty  provides  that it is a guaranty  of
                         both  the  performance  and  payment  of the  financial
                         obligations  of the  Credit  Tenant,  and  not  only of
                         collection;  and (v) the  guaranty  is  binding  on the
                         guarantor,  its  successors  and assigns and may not be
                         amended or released without the Trustee's consent;

                    (W)  the Mortgaged  Property has a permanent  certificate of
                         occupancy  and the Credit  Tenant has  commenced  lease

                    account of payments due on the Note or Mortgage;

          (xlix)    To the best of the Seller's  knowledge,  there is no pending

                    investigation against the borrower or the Mortgaged Property

                    documents permit the lender,  following a default under such
                    Mortgage  Loan,  to apply funds  received in respect of such
                    Mortgage Loan to amounts owing thereunder in the order which
                    the lender deems appropriate.

     (c) The Seller has not dealt with any broker,  investment banker,  agent or

     3. Notice of Breach;  Cure and Repurchase.  (a) Pursuant to the Pooling and
Servicing Agreement, the Seller and the Company shall be given notice of (A) any
breach of any  representation  or warranty  contained in Section 2(b) (i), (ii),

holders of the Certificates therein.

     (b) Within 90 days of the  receipt  of the  notice (or with  respect to the
representation and warranty contained in Section 2(b)(xxix) or (xxx), discovery)
of a breach  provided for in clause (a), the Seller shall either (i)  repurchase
the related  Mortgage  Loan at the  Repurchase  Price or (ii) promptly cure such
breach in all material respects;  provided, however, that in the event that such
breach (other than a breach of Section  2(b)(xxix) or (xxx)) is capable of being
cured but not within  such 90 day period  and the  Seller has  commenced  and is
diligently  proceeding  with the cure of such breach  within such 90 day period,
the Seller shall have an  additional  90 days to complete  such cure,  provided,
further,  that with  respect to such  additional  90 day period the Seller shall
have delivered an officer's  certificate to the Trustee setting forth the reason
such breach is not  capable of being cured  within the initial 90 day period and
what  actions  the Seller is pursuing in  connection  with the cure  thereof and
stating  that the Seller  anticipates  that such breach will be cured within the
additional  90 day period;  and  provided,  further,  that in the event that the
Seller fails to complete the cure of such breach  within such  additional 90 day
period,  the Repurchase Price shall also include interest at the Advance Rate on
any Advance made by the Servicer in respect of the related  Mortgage Loan.  Upon
any such repurchase of a Mortgage Loan by Seller,  the Company shall execute and
deliver such instruments of transfer or assignment presented to it by Seller, in
each case  without  recourse,  as shall be necessary to vest in Seller the legal

its  obligations or satisfy any of the conditions on its part to be performed or

     2.  Representations  and Warranties.  (a) The Seller hereby  represents and
warrants to the Company as of the Closing Date that:

          (i)       The  Seller is a  business  trust  duly  organized,  validly
                    existing and in good standing under the laws of the State of
                    Delaware  with  full  power  and  authority  to carry on its
                    business as presently conducted by it;

          (ii)      The Seller has taken all  necessary  action to authorize the
                    execution, delivery and performance of this Agreement by it,
                    and has the power and  authority  to  execute,  deliver  and
                    perform this Agreement and all the transactions contemplated
                    hereby,  including,  but  not  limited  to,  the  power  and
                    authority to sell, assign and transfer the Mortgage Loans in
                    accordance with this Agreement;

          (iii)     Assuming the due  authorization,  execution  and delivery of
                    this Agreement by the Company, this Agreement and all of the
                    obligations of the Seller hereunder are the legal, valid and
                    binding obligations of the Seller, enforceable in accordance
                    with the terms of this Agreement, except as such enforcement
                    may be limited by  bankruptcy,  insolvency,  reorganization,
                    liquidation, receivership, moratorium or other laws relating
                    to or affecting  creditors' rights generally,  or by general
                    principles   of   equity   (regardless   of   whether   such
                    enforceability is considered in a proceeding in equity or at
                    law);

          (iv)      The  execution  and  delivery  of  this  Agreement  and  the
                    performance of its obligations  hereunder by the Seller does
                    not conflict  with any provision of any law or regulation to
                    which the Seller is subject,  or conflict with,  result in a
                    breach of or  constitute  a default  under any of the terms,
                    conditions  or  provisions of any agreement or instrument to
                    which the Seller is a party or by which it is bound,  or any
                    order or decree  applicable to the Seller,  or result in the
                    creation or  imposition  of any lien on any of the  Seller's
                    assets or property,  which would  materially  and  adversely
                    affect   the   ability  of  the  Seller  to  carry  out  the
                    transactions  contemplated by this Agreement. The Seller has
                    obtained any consent,  approval,  authorization  or order of
                    any court or  governmental  agency or body  required for the
                    execution,  delivery and  performance  by the Seller of this
                    Agreement; and

          (v)       There is no action,  suit or proceeding  pending against the
                    Seller in any court or by or before  any other  governmental
                    agency  or   instrumentality   which  would  materially  and
                    adversely  affect the ability of the Seller to carry out its
                    obligations  under this Agreement or have a material adverse
                    effect  on the  financial  condition  of the  Seller  or the
                    ability of the Seller to perform its obligations  under this
                    Agreement.

     (b) The Seller hereby represents and warrants with respect to each Mortgage
Loan that as of the date specified below or, if no such date is specified, as of
the Closing Date:

          (i)       Immediately  prior to the sale,  transfer and  assignment to
                    the Company,  each related Note and Mortgage was not subject
                    to an assignment  (other than to the Seller) or pledge,  and
                    the  Seller  had good and  marketable  title to, and was the
                    sole owner of, the Mortgage Loan;

          (ii)      The Seller has full right and authority to sell,  assign and
                    transfer  such  Mortgage  Loan  and  the  assignment  to the
                    Company constitutes a legal, valid and binding assignment of
                    such Mortgage;

          (iii)     The Seller is transferring such Mortgage Loan free and clear
                    of any and all liens, pledges, charges or security interests
                    of any nature  encumbering such Mortgage Loan subject to the
                    matters described in clause (xi) below;

          (iv)      Each related Note, Mortgage,  Assignment of Leases and Rents
                    (if any) and other  agreement  executed in  connection  with
                    such Mortgage Loan are legal, valid and binding  obligations
                    of the related  Borrower,  enforceable  in  accordance  with
                    their terms,  except as such  enforcement  may be limited by
                    bankruptcy, insolvency, reorganization,  moratorium or other
                    laws  affecting  the   enforcement   of  creditors'   rights
                    generally, or by general principles of equity (regardless of
                    whether such enforceability is considered in a proceeding in
                    equity or at law) and to the best of the Seller's knowledge,
                    there is no valid defense, counterclaim, right of rescission
                    or right of set-off or  abatement  available  to the related
                    Borrower  with  respect  to such  Note,  Mortgage  and other
                    agreements;

          (v)       Each related Assignment of Leases and Rents creates a valid,
                    collateral or first priority assignment of, or a valid first
                    priority  security  interest  in,  certain  rights under the
                    related  lease,  subject  only to a license  granted  to the
                    related  Borrower to exercise  certain rights and to perform
                    certain   obligations   of  the  lessor  under  such  lease,
                    including  the  right  to  operate  the  related   Mortgaged
                    Property; no person other than the related Borrower owns any
                    interest  in any  payments  due  under  such  lease  that is
                    superior  to or  of  equal  priority  with  the  mortgagee's
                    interest therein;

          (vi)      Each related  assignment  of Mortgage from the Seller to the
                    Company and any related Reassignment of Assignment of Leases
                    and Rents,  if any,  or  assignment  of any other  agreement
                    executed in  connection  with such Mortgage  Loan,  from the
                    Seller  to the  Company  constitutes  the  legal,  valid and
                    binding assignment from the Seller to the Company, except as
                    such  enforcement may be limited by bankruptcy,  insolvency,
                    reorganization,  liquidation,  receivership,  moratorium  or
                    other  laws  relating  to  or  affecting  creditors'  rights
                    generally, or by general principles of equity (regardless of
                    whether such enforceability is considered in a proceeding in
                    equity or at law);

          (vii)     Since  origination,  and except as set forth in the  related
                    Mortgage  File,  such  Mortgage  Loan has not  been  waived,
                    modified,  altered,  satisfied,  canceled,  subordinated  or
                    rescinded and, each related Mortgaged  Property has not been
                    released from the lien of the related Mortgage in any manner
                    which materially interferes with the security intended to be
                    provided by such Mortgage;

          (viii)    Each related Mortgage is a valid and enforceable  first lien
                    on  the  related  Mortgaged  Property,  and  such  Mortgaged
                    Property  (subject to the matters  described  in clause (xi)
                    below),   is  free   and   clear  of  any   mechanics'   and
                    materialmen's  liens  which are  prior to or equal  with the
                    lien of the related Mortgage, except those which are insured
                    against by a lender's title  insurance  policy (as described
                    below);

          (ix)      The  Seller has not taken any  action  that would  cause the
                    representations and warranties made by each related Borrower
                    in the Mortgage Loan not to be true;

          (x)       The Seller has no  knowledge  that the  representations  and
                    warranties  made by each related  Borrower in such  Mortgage
                    Loan are not true in any material respect;

          (xi)      The lien of each  related  Mortgage  is  insured  by an ALTA
                    lender's  title  insurance  policy (or a binding  commitment
                    therefor),  or its  equivalent as adopted in the  applicable
                    jurisdiction,   insuring  the  Seller,  its  successors  and
                    assigns, or the holder of the related Note as to a valid and
                    first priority lien of the Mortgage in at least the original
                    principal  amount of such  Mortgage  Loan or Allocated  Loan
                    Amount of the related  Mortgaged  Property  (as set forth on
                    the  Mortgage  Loan  Schedule  which  is an  exhibit  to the
                    Pooling and  Servicing  Agreement),  subject only to (a) the
                    lien of current real property  taxes,  ground  rents,  water
                    charges,  sewer  rents  and  assessments  not  yet  due  and
                    payable, (b) covenants, conditions and restrictions,  rights
                    of way,  easements and other matters of public record,  none
                    of  which,  individually  or in  the  aggregate,  materially
                    interferes   with  the  current  use  or  operation  of  the
                    Mortgaged  Property or the security  intended to be provided
                    by such Mortgage or with the  Borrower's  ability to pay its
                    obligations  when  they  become  due  or  the  value  of the
                    Mortgaged  Property  and (c)  the  exceptions  (general  and
                    specific)   set  forth  in  such  policy,   none  of  which,
                    individually or in the aggregate, materially interferes with
                    the  security  intended to be  provided by such  Mortgage or
                    with the related  Borrower's  ability to pay its obligations
                    when they become due or the value,  use or  operation of the
                    Mortgaged Property;  the Seller or its successors or assigns
                    is the sole named  insured of such  policy;  such  policy is
                    assignable  to the  Company  without  the  consent of or any
                    notification to the insurer, and is in full force and effect
                    upon the  consummation of the  transactions  contemplated by
                    this  Agreement;  no claims have been made under such policy
                    and the Seller has not done  anything,  by act or  omission,
                    and the Seller has no knowledge  of any matter,  which would
                    impair or  diminish  the  coverage  of such  policy;  to the
                    extent  required by applicable law, the insurer issuing such
                    policy is  qualified to do business in the  jurisdiction  in
                    which the related Mortgaged Properties are located;

          (xii)     The proceeds of such Mortgage Loan have been fully disbursed
                    and there is no requirement for future  advances  thereunder
                    and the  Seller  covenants  that it will not make any future
                    advances under the Mortgage Loan to the related Borrower;

          (xiii)    Each  related  Mortgaged  Property  is free of any  material
                    damage that would affect  materially and adversely the value
                    of such Mortgaged Property as security for the Mortgage Loan
                    and there is no proceeding  pending for the total or partial
                    condemnation of such Mortgaged Property;

          (xiv)     Each of the related Borrowers (and, if the related Mortgaged
                    Property  is  secured  by a  senior  housing  or  healthcare
                    facility,  each of the  operators  of such  facility)  is in
                    possession  of all  material  licenses,  permits  and  other
                    authorizations necessary and required by all applicable laws
                    for the  conduct  of its  business  and all  such  licenses,
                    permits and  authorizations  are valid and in full force and
                    effect, and if a related Mortgaged Property is improved by a
                    healthcare facility, the most recent inspection or survey by
                    governmental  authorities having  jurisdiction in connection
                    with such licenses,  permits and authorizations did not cite
                    such Mortgaged Property for material violations (which shall
                    include only "Level A" violations or the equivalent,  in the
                    case of  skilled  nursing  facilities,  that  have  not been
                    cured); and if a related Mortgaged Property is improved by a
                    hotel,   the  most  recent   inspection  or  review  by  the
                    franchisor, if any, did not cite such Mortgaged Property for
                    material violations of the related franchise agreement which
                    have not been cured;

          (xv)      The Seller or, to the best of Seller's knowledge, Bloomfield
                    has  inspected  or  caused  to  be  inspected  each  related
                    Mortgaged  Property within the past 12 months  preceding the
                    Cut-off  Date  or  within  1  month  of  origination  of the

                    feature,  other  contingent  interest  feature  or  negative
                    amortization;

          (xvii)    Such  Mortgage Loan is a whole loan and no other party holds
                    an interest in the Mortgage Loan;

          (xviii)   (A) The Mortgage Rate  (exclusive  of any default  interest,
                    late charge or yield  maintenance  charge) of such  Mortgage
                    Loan  complied  as of the date of  origination  with,  or is
                    exempt from,  applicable state or federal laws,  regulations
                    and other  requirements  pertaining  to  usury;  any and all
                    other  requirements  of any  federal,  state or local  laws,
                    including, without limitation, truth-in-lending, real estate
                    settlement   procedures,   equal   credit   opportunity   or
                    disclosure laws,  applicable to such Mortgage Loan have been
                    complied with as of the date of origination of such Mortgage
                    Loan and (B) the Seller has  received  an opinion  that such
                    Mortgage Loan is not usurious;

          (xix)     (A) With respect to each  Mortgage  Loan  originated  by the
                    Seller,  no  fraudulent  acts were  committed  by the Seller
                    during the origination process of such Mortgage Loan and the
                    origination,  servicing and collection of each Mortgage Loan
                    is in all respects  legal,  proper and prudent in accordance
                    with  customary  industry  standards and (B) with respect to
                    each Mortgage Loan originated by Bloomfield,  to the best of
                    the Seller's knowledge, no fraudulent acts were committed by
                    Bloomfield  during the origination  process of such Mortgage
                    Loan and the  origination,  servicing and collection of each
                    Mortgage Loan is in all respects  legal,  proper and prudent
                    in accordance with customary industry standards;

          (xx)      All taxes and  governmental  assessments  that  prior to the
                    Closing  Date  became  due and  owing in  respect  of,  each
                    related  Mortgaged  Property  have been paid or an escrow of
                    funds in an amount  sufficient  to cover such  payments  has

                    Mortgage Loans are in the possession,  or under the control,
                    of the Seller or its agent and there are no  deficiencies in
                    connection  therewith and all such escrows and deposits have
                    been conveyed by the Seller to the Company and identified as
                    such with appropriate detail;

          (xxii)    To the  extent  required  under  applicable  law,  as of the
                    Cut-off Date,  the Seller was  authorized to transact and do
                    business in the jurisdiction in which each related Mortgaged
                    Property  is located at all times when it held the  Mortgage
                    Loan;

          (xxiii)   (A) Each related Mortgaged Property is insured by a fire and
                    extended  perils  insurance  policy,  issued  by an  insurer
                    meeting the requirements  under the related Mortgage Loan in
                    an amount not less than the replacement  cost and the amount
                    necessary  to  avoid  the  operation  of  any   co-insurance
                    provisions  with respect to the Mortgaged  Property,  except
                    with  respect  to  certain  portions  of  certain  Mortgaged
                    Properties  in which a Credit  Tenant  self-insures  for its
                    portion of such Mortgaged Property;

                    (B)  Each related Mortgaged  Property is covered by business

                         interruptions)  and each Mortgaged  Property is covered
                         by comprehensive general liability insurance in amounts

                         insured of  termination  or  cancellation,  and no such
                         notice has been received; and

                    (E)  Each related  Mortgage or Loan Agreement  obligates the
                         related Borrower to maintain all such insurance and, at
                         such  Borrower's  failure  to  do  so,  authorizes  the
                         mortgagee to maintain such  insurance at the Borrower's
                         cost and  expense  and to seek  reimbursement  therefor
                         from such Borrower;

          (xxiv)    There  is  no  default,   breach,   violation  or  event  of
                    acceleration  existing  under the  related  Mortgage  or the
                    related Note and, to the Seller's knowledge, no event which,
                    with the passage of time or with  notice and the  expiration
                    of any grace or cure  period,  would and does  constitute  a
                    default, breach, violation or event of acceleration;

          (xxv)     Such Mortgage  Loan has not been 30 days or more  delinquent
                    since  origination  and  as of  the  Cut-off  Date  was  not
                    delinquent;

          (xxvi)    Each related  Mortgage  contains  customary and  enforceable
                    provisions  such as to render the rights and remedies of the
                    holder  thereof  adequate  for the  realization  against the
                    Mortgaged   Property  of  the  benefits  of  the   security,
                    including   realization   by  judicial  or,  if  applicable,
                    non-judicial   foreclosure,   and  there  is  no   exemption
                    available to the Borrower  which would  interfere  with such
                    right to foreclose.  To the best of the Seller's  knowledge,
                    no Borrower is a debtor in a state or federal  bankruptcy or
                    insolvency preceding;

          (xxvii)   In each  related  Mortgage  or Loan  Agreement,  the related
                    Borrower  represents and warrants that,  except as set forth
                    in  certain   environmental   reports  or  other   documents
                    previously  provided to the Rating  Agencies and to the best
                    of its  knowledge,  it has not used,  caused or permitted to
                    exist  and  will not use,  cause or  permit  to exist on the
                    related  Mortgaged  Property any Hazardous  Materials in any
                    manner  which  violates   federal,   state  or  local  laws,
                    ordinances,  regulations,  orders,  directives  or  policies
                    governing  the  use,  storage,  treatment,   transportation,
                    manufacture, refinement, handling, production or disposal of
                    Hazardous   Materials;   the  related   Borrower  agrees  to
                    indemnify,  defend and hold the mortgagee and its successors
                    and  assigns  harmless  from and against any and all losses,
                    liabilities,  damages, injuries, penalties, fines, expenses,
                    and claims of any kind whatsoever (including attorneys' fees
                    and  costs)  paid,  incurred  or  suffered  by, or  asserted
                    against,  any such party  resulting from a breach of certain
                    representations,   warranties  or  covenants  given  by  the
                    Borrower  in  such  Mortgage  or Loan  Agreement.  A Phase I
                    environmental   report   was   conducted   by  a   reputable
                    environmental  engineer  in  connection  with such  Mortgage
                    Loan,   which   report  does  not   indicate   any  material
                    non-compliance or material existence of Hazardous Materials,
                    except as disclosed  in the  Prospectus  Supplement  and the
                    Prospectus,   each  dated  March  27,   1998  (under   "Risk
                    Factors--The     Mortgage      Loans--Environmental      Law
                    Considerations" in the Prospectus  Supplement).  To the best
                    of the Seller's knowledge,  each related Mortgaged Property,
                    except  as  disclosed  in  the  Prospectus,  is in  material
                    compliance with all applicable federal, state and local laws
                    pertaining  to  environmental  hazards,  and to the  best of
                    Seller's knowledge,  no notice of violation of such laws has
                    been issued by any  governmental  agency or  authority;  the
                    Seller  has not  taken  any  action  which  would  cause the
                    related Mortgaged  Property not to be in compliance with all
                    federal,  state and local laws  pertaining to  environmental
                    hazards;

          (xxviii)  Each related Mortgage or Loan Agreement contains  provisions
                    for the  acceleration of the payment of the unpaid principal
                    balance of such Mortgage Loan if, without complying with the
                    requirements  of the Mortgage or Loan Agreement or obtaining
                    the  prior   written   consent  of  the   Mortgagee  or  the
                    satisfaction of certain  conditions,  the related  Mortgaged
                    Property, or any interest therein, is directly or indirectly
                    transferred  or  sold,  or  encumbered  in  connection  with
                    subordinate  financing and each related  Mortgage  prohibits
                    the pledge or encumbrance of the Mortgaged  Property without
                    the consent of the holder of the Mortgage Loan;

          (xxix)    (1) The Mortgage Loan is directly secured by a Mortgage on a
                    commercial property or multifamily residential property, and
                    (2) the fair market value of such real property was at least
                    equal to 80% of the  principal  amount of the Mortgage  Loan
                    (a) at  origination  (or  if  the  Mortgage  Loan  has  been
                    modified  in a manner  that  constituted  a deemed  exchange
                    under  Section  1001 of the Code at a time when the Mortgage
