     Pooling and Servicing Agreement,  dated as of October 24, 1997, among Asset
Securitization Corporation,  as Depositor,  AMRESCO Services, L.P., as Servicer,
AMRESCO Management, Inc., 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-1D,  Class A-CS1,  Class PS-1,
Class A-1E,  Class A-2,  Class A-3,  Class A-4, Class A-5, Class A-6, Class A-7,
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 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  twenty-one  Classes of  uncertificated  Lower-Tier  Regular  Interests
issued under this Agreement (the Class A-1A-L, Class A-1B-L, Class A-1C-L, Class
A-1D-L,  Class A-1E-L, Class A-2-L, Class A-3-L, Class A-4-L, Class A-5-L, Class
A-6-L, Class A-7-L,  Class A-8Z-L,  Class B-1-L, Class B-2-L, Class B-3-L, Class
B-3SC-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.

           Class                     Certificate Balance or Notional Balance

           Class A-1A                              $  165,018,148.00
           Class A-1B                                 172,648,684.00

(1)  The initial  Notional  Balance of Class PS-1  Certificates  is equal to the
     aggregate  Stated  Principal  Balance of the Mortgage Loans (other than the
     Comsat  Junior Loan and the SC Junior  Portion of the Saul  Centers  Retail
     Pool Loan) as of the Cut-off Date.

(2)  The initial Notional Balance of the Class CS-1 Certificates is equal to the
     initial Certificate Balance of the Class A-1A Certificates.

     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  (other  than with  respect to the Class
A-8Z  Certificates  due to  capitalized  interest  on the Comsat  Junior  Loan);
provided,  however,  that in the event  that  amounts  previously  allocated  as
Realized Losses (or with respect to the Class A-8Z and Class B-3SC Certificates,
Class A-8Z Realized Losses and Class B-3SC Realized  Losses,  respectively) 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 (other than the Comsat Junior
Loan and the SC Junior  Portion of the Saul  Centers  Retail  Pool Loan) have an
aggregate Stated Principal Balance equal to approximately $1,754,015,636.

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

     SECTION 1.01.Defined.

     Whenever used in this Agreement,  the following  words and phrases,  unless
the  context  otherwise  requires,  shall have the  meanings  specified  in this
Article.

reimbursed and Servicing Fees,  Trustee Fees or Special  Servicing  Compensation
for which the Servicer, the Trustee or the Special Servicer, as applicable,  has
not been timely paid or reimbursed for the number of days from the date on which
such Advance was made or such Servicing Fees,  Trustee Fees or Special Servicing
Compensation  were due  through  the date of  payment  or  reimbursement  of the
related  Advance or other such  amount,  less any amount of interest  previously
paid on such  Advance or  Servicing  Fees,  Trustee  Fees or  Special  Servicing
Compensation;  provided,  that, with respect to a P&I Advance, in the event that
the related  Borrower  makes  payment of the amount in respect of which such P&I
Advance was made with interest at the Default Rate, the Advance  Interest Amount
payable to the Servicer, the Trustee or the Fiscal Agent shall be paid (i) first
from the amount of Default  Interest paid by the Borrower and (ii) to the extent
such  amounts  are  insufficient  therefor,  from  amounts  on  deposit  in  the
Collection  Account  other than amounts  with respect to the Comsat  Junior Loan
(or,  in the case of Class  A-8Z P&I  Advances  or Class  B-3SC  Advances,  from

Loan  and  the  SC  Junior  Portion  of  the  Saul  Centers  Retail  Pool  Loan,
respectively).

     "Advance Rate": A per annum rate equal to the sum of (i) the Prime Rate (as

monthly as of each Servicer  Remittance Date.  Interest at the Advance Rate will
accrue from (and including) the date on which the related Advance is made or the
related  expense  incurred to (but excluding) the date on which such amounts are
recovered out of amounts received on the Mortgage Loan as to which such Advances
were made or servicing  expenses incurred or the first Servicer  Remittance Date
after a  determination  of  non-recoverability,  as the  case  may be,  is made,
provided  that such  interest at the Advance Rate will continue to accrue to the
extent funds are not available in the Collection  Account for such reimbursement
of such Advance.

     "Affiliate":  With  respect  to any  specified  Person,  any  other  Person

specified  Person means the power to direct the  management and policies of such
Person,  directly  or  indirectly,  whether  through  the  ownership  of  voting
securities,   by  contract  or  otherwise,   and  the  terms  "controlling"  and
"controlled" have meanings correlative to the foregoing.  The Trustee may obtain
and rely on an Officers'  Certificate of the Servicer,  the Special Servicer, or
the Depositor to determine whether any Person is an Affiliate of such party.

     "Affiliated  Person":  Any Person (other than a Rating Agency)  involved in
the  organization  or operation of the Depositor or an affiliate,  as defined in
Rule 405 of the Act, of such Person.

Mortgaged  Property in the applicable  Mortgage,  Loan Agreement or the Mortgage
Loan Schedule.

compliance  required  by  Section  3.14  hereof  and  an  annual  report  of  an
Independent accountant required pursuant to Section 3.15 hereof.

     "Anticipated  Repayment  Date":  With respect to any Mortgage  Loan that is
indicated on the Mortgage Loan Schedule as having a Revised  Mortgage  Rate, the
date upon which such Mortgage Loan commences  accruing  interest at such Revised

     "Anticipated  Termination  Date":  Any  Distribution  Date on  which  it is
anticipated that the Trust Fund will be terminated pursuant to Section 9.01(c).

     "Applicable Monthly Payment":  As defined in Section 4.06(a).

     "Applicable Procedures":  As defined in Section 5.02(b).

     "Appraisal  Reduction  Amount":  For  any  Distribution  Date  and  for any
Mortgage Loan other than the Comsat Junior Loan and the SC Junior Portion of the
Saul  Centers  Retail  Pool Loan as to which an  Appraisal  Reduction  Event has
occurred,  an amount  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  annum  rate  equal  to  its  Mortgage  Rate,  (B)  all
unreimbursed Property Advances and the principal portion of all unreimbursed P&I
Advances, and all unpaid interest on Advances at the Advance Rate, in respect of
such  Mortgage  Loan and (C) all  currently  due and unpaid real  estate  taxes,

and unpaid with respect to such Mortgage  Loan (which taxes,  premiums and other
amounts have not been the subject of an Advance by the Servicer,  the Trustee or
the Fiscal  Agent,  as  applicable).  If no Updated  Appraisal has been obtained
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 30 days 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 shall also be adjusted to take into account any
subsequent  Updated Appraisal and annual letter updates,  as of the date of each
such subsequent Updated Appraisal or letter update.

     "Appraisal  Reduction Event":  With respect to any Mortgage Loan, the first
Distribution  Date  following the earliest of (i) the third  anniversary  of the
date on which an extension of the Maturity  Date of such  Mortgage  Loan becomes
effective as a result of a  modification  of such  Mortgage  Loan by the Special
Servicer  pursuant  to the terms  hereof,  which  extension  does not change the
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) 90 days after
an uncured  Delinquency  (without regard to the application of any grace period)
occurs in respect of such Mortgage  Loan,  (iii)  immediately  after 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) immediately after a receiver
has been appointed,  (v) immediately after a borrower declares bankruptcy,  (vi)
immediately  after a Mortgage  Loan becomes an REO Mortgage  Loan,  (vii) upon a
default  in the  payment  of a  Balloon  Payment,  (viii)  immediately  upon the
occurrence of an event for which a Property Advance would be required to be made
by the Servicer or (ix) any other event which, in the discretion of the Servicer
and of which the Servicer becomes aware in performing its obligations hereunder,
in accordance with the Servicing Standard, would materially and adversely impair
the value of a Mortgaged  Property and security for the related  Mortgage  Loan.
The Special  Servicer shall notify the Servicer  promptly upon the occurrence of
any of the foregoing events.

     "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

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
Property  is  located  to  reflect  of record  the sale of the  Mortgage,  which
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 and
the Servicer  shall be  responsible  for  determining  whether any assignment is
legally sufficient or in recordable form.

     "Assumed  Maturity  Date":  With respect to any Mortgage Loan that is not a
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.

receipts on account of principal and interest  (including  Unscheduled  Payments
and any Net REO  Proceeds  transferred  from an REO Account  pursuant to Section
3.17(b)) on or in respect of the Mortgage Loans, received by the Servicer in the
Collection  Period  relating to such  Distribution  Date, (ii) all other amounts

the  Collection  Account by the Servicer  pursuant to Section 3.05  allocable to

Advance  Amounts)  made by the  Servicer,  the  Trustee or the  Fiscal  Agent in

previously  made which has not been previously  reimbursed to the Servicer,  the
Special Servicer, the Trustee or the Fiscal Agent, as applicable,  and which, in
the good faith  business  judgment of the Servicer,  the Special  Servicer,  the
Trustee  or the  Fiscal  Agent,  as  applicable,  will not or,  in the case of a
proposed  Advance,  would not be  ultimately  recoverable  from  late  payments,
Insurance Proceeds,  Liquidation Proceeds and other collections on or in respect
of the related Mortgage Loan. The judgment or determination by the Servicer, the
Special  Servicer,  the  Trustee  or  the  Fiscal  Agent  that  it  has  made  a
Nonrecoverable Advance or that any proposed Advance, if made, would constitute a
Nonrecoverable Advance shall be evidenced in the case of the Servicer or Special
Servicer,  by a certificate of a Servicing Officer delivered to the Trustee, the

of a  Responsible  Officer  of the  Trustee  or  Fiscal  Agent,  as  applicable,
delivered  to the  Depositor  (and the  Trustee if the  Certificate  is from the
Fiscal Agent),  which in each case sets forth such judgment or determination and
the procedures and considerations of the Servicer,  Special Servicer, Trustee or
Fiscal Agent, as applicable, forming the basis of such determination (including,

determination in its good faith  discretion,  such as related income and expense
statements,  rent  rolls,  occupancy  status,  property  inspections,  Servicer,

non-recoverability  made by the Servicer may be made without regard to any value
determination  made by the Special  Servicer  other than  pursuant to an Updated
Appraisal.  Notwithstanding the above, the Trustee and the Fiscal Agent shall be
entitled  to rely  upon any  determination  by the  Servicer  that  any  Advance
previously made is a Nonrecoverable  Advance or that any proposed Advance would,
if made, constitute a Nonrecoverable Advance (and with respect to a proposed P&I
Advance,  the Trustee and the Fiscal  Agent,  as  applicable,  shall rely on the

or any  political  subdivision  thereof,  an estate  whose  income is subject to
United States  federal  income tax  regardless of its source,  or a trust if for
taxable  years  beginning  after  December 31, 1996 (or for taxable years ending
after August 20, 1996, if the trustee has made an  applicable  election) a court
within  the  United  States is able to  exercise  primary  supervision  over the
administration  of such  trust,  and one or more  such  U.S.  Persons  have  the
authority to control all substantial  decisions of such trust (or, to the extent
provided in  applicable  Treasury  Regulations,  certain  trusts in existence on
August 20, 1996 which are eligible to elect to be treated as U.S. Persons).

     "Voting  Rights":   The  portion  of  the  voting  rights  of  all  of  the
Certificates  that is allocated to any Certificate or Class of Certificates.  At
all times during the term of this Agreement, the percentage of the Voting Rights
assigned  to each Class  shall be (a) 0%, in the case of the Class  A-8Z,  Class
B-3SC, Class V-1, Class V-2, Class R and Class LR Certificates, (b) 0.17% in the
case of the  Class  A-CS1  Certificates,  5.19%  in the case of the  Class  PS-1
Certificates (the sum of such percentages for each such Class outstanding is the
"Fixed  Voting Rights  Percentage");  provided that the Voting Rights of (i) the
Class  ACS-1  Certificates  will be  reduced to zero upon the  reduction  of the
Notional  Balance  of such class to zero,  and (ii) the Class PS-1  Certificates
will be  reduced  to zero on the  Distribution  Date on which  none of the A-1B,
Class A-1C,  Class A-1D, Class A-1E, Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5,  Class A-6,  Class A-7,  Class B-1,  Class B-2, Class B-3, Class B-4,
Class B-5 and Class B-6 Certificates are outstanding,  (c) in the case of any of
the Class A-1A, Class A-1B, Class A-1C, Class A-1D, Class A-1E, Class A-2, Class
A-3,  Class A-4,  Class A-5,  Class A-6,  Class A-7, 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,  a
percentage  equal to the  product  of (i) 100%  minus  the Fixed  Voting  Rights
Percentage multiplied by (ii) a fraction, the numerator of which is equal to the
aggregate outstanding  Certificate Balance of any such Class and the denominator
of which  is equal to the  aggregate  outstanding  Certificate  Balances  of all
Classes of Certificates. The Class A-CS1, Class PS-1, Class A-8Z and Class B-3SC
Certificates  shall not be entitled to vote with respect to proposed  extensions
of a Specially Serviced Mortgage Loan;  provided,  however,  that the Class A-8Z
Certificate  shall be entitled to vote solely with respect to  extensions of the
Comsat Junior Loan if the Comsat  Senior Loan has been paid in full.  The Voting
Rights  of any  Class  of  Certificates  shall be  allocated  among  Holders  of
Certificates  of  such  Class  in  proportion  to  their  respective  Percentage
Interests.  The  aggregate  Voting  Rights of  Holders of more than one Class of
Certificates  shall be equal to the sum of the  products  of each such  Holder's
Voting Rights and the percentage of Voting Rights allocated to the related Class
of Certificates.  Any  Certificateholder  may transfer its Voting Rights without
transferring its ownership  interest in the related  Certificates  provided that
such Certificateholder  provides notice of such transfer to the Trustee prior to
the  effectiveness  of  such  transfer.  The  Voting  Rights  of each  Class  of
Certificates  will be  deemed  to be  reduced  on any day on which an  Appraisal
Reduction  Amount is allocated to such Class  pursuant to Section  4.06(e).  The
Fixed  Voting  Right  Percentage  of  the  Class  A-CS1  Certificates  shall  be
proportionally  reduced upon the allocation of Appraisal  Reduction Amounts with
respect to the Class A-1A Certificates  pursuant to Section 4.06(e) based on the
amount of such  reduction.  The Fixed Voting Right  Percentage of the Class PS-1
Certificates  shall be  proportionally  reduced upon the allocation of Appraisal
Reduction  Amounts to the Class A-1B,  Class A-1C, Class A-1D, Class A-1E, Class
A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class B-1, Class B-2
Class B-3,  Class B-4 Class B-5 and Class B-6  Certificates  pursuant to Section
4.06(e) based on the amount of such reduction.

Exhibit M-6 attached  hereto,  setting forth,  among other things,  any Mortgage
Loan that is in jeopardy of becoming a Specially Serviced Mortgage Loan.
    

     "Weighted  Average Net  Mortgage  Pass-Through  Rate":  With respect to any
Distribution  Date,  a per annum  rate  equal to the  fraction  (expressed  as a
percentage)  the numerator of which is the sum of the products for each Mortgage
Loan  other than the Comsat  Junior  Loan and the SC Junior  Portion of the Saul
Centers  Retail  Pool Loan of (i) the Net  Mortgage  Pass-Through  Rate for such
Mortgage  Loan and (ii) the Stated  Principal  Balance of such Mortgage Loan and
the denominator of which is the sum of the Stated Principal Balances of all such
Mortgage Loans, as of their respective Due Date preceding the prior Distribution
Date.

     "Weighted Average  Pass-Through Rate": With respect to any Interest Accrual
Period,  a fraction  (expressed as a percentage),  the numerator of which is the
sum of (i) the sum of the products of (A) the Pass-Through  Rate with respect to
each class of  Certificates  having a  Pass-Through  Rate  (other than the Class
PS-1,  Class  A-CS1,  Class  A-8Z  and  Class  B-3SC  Certificates)  and (B) the
Certificate  Balance of such Class as of the first day of such Interest  Accrual
Period and (ii) the  product  of (A) the  Pass-Through  Rate on the Class  A-CS1
Certificates  and (B) the Notional Balance of such class as of such date and the
denominator  of  which  is the sum of the  Certificate  Balances  of each  class
included in clause (i)(A) above as of such date (provided in the case of clauses
(i) and (ii), any reductions in Certificate Balance as a result of distributions
or allocations of Realized Losses to such class,  respectively,  occurring in an
Interest  Accrual  Period  shall be deemed to have been made on the first day of

than the Actual/360 Mortgage Loans) and of Advances provided for herein shall be
made on the basis of a 360-day year  consisting  of twelve  30-day  months.  All
calculations  of interest with respect to the  Actual/360  Mortgage Loans and of
Advances  provided for herein shall be made as set forth in such Mortgage  Loans
with respect to the calculation of the related Mortgage Rate.

     (b) Any  Mortgage  Loan  payment is deemed to be  received on the date such
payment is actually received by the Servicer, or the Trustee; provided, however,
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",
"Special  Servicing Fee", Section 3.19, Section 3.12, Section 3.25, Section 3.30

Classes of Related Lower-Tier Regular Interests, and shall expressly not include
the  Class  A-8Z  Certificates  or the  Class  B-3SC  Certificates  (or  Related
Lower-Tier Regular Interests)).  For such purposes, the Class B-7 and Class B-7H
Certificates (and the Classes of Related Lower-Tier Regular Interests)  together
shall be considered to be one Class and the Class A-1A,  Class A-1B, Class A-1C,
Class A-1D, Class A-CS1 and Class PS-1  Certificates (and the Classes of Related

For purposes of this Agreement,  each Class of Certificates other than the Class
V-1,  Class  V-2,  Class  LR and  Class R  Certificates  shall be  deemed  to be

reduced to zero.  For  purposes of this  Agreement,  the Class V-1  Certificates
shall be deemed to be  outstanding  so long as there are any Notes  outstanding,

and the Class R and Class LR  Certificates  shall be deemed to be outstanding so
long as the Trust Fund has not been  terminated  pursuant to Section  9.01.  For
purposes of this Agreement, the Class A-CS1 and Class PS-1 Certificates shall be
deemed to be  outstanding  until their  respective  Notional  Balances have been
reduced to zero.

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES


     SECTION  2.01.Conveyance  of Mortgage  Loans;  Assignment  of Mortgage Loan
Purchase and Sale Agreement.

     The Depositor,  concurrently  with the execution and delivery hereof,  does
hereby sell,  transfer,  assign,  set over and  otherwise  convey to the Trustee
without recourse (except to the extent herein provided) all the right, title and
interest of the Depositor in and to the Mortgage Loans  (including the Westin GC
Participation (except to the extent the Other Participant has an interest in the
related loan  documents)),  including all rights to payment in respect  thereof,
except as set forth below, and any security interest thereunder (whether in real
or  personal  property  and  whether  tangible  or  intangible)  in favor of the
Depositor, and all Reserve Accounts, Lock-Box Accounts, Cash Collateral Accounts
and all other  assets  included  or to be  included  in the  Trust  Fund for the
benefit of the  Certificateholders.  Such transfer and  assignment  includes all
interest and  principal  due on or with respect to the Mortgage  Loans after the
Cut-off Date (but excluding interest accrued prior to the 17th day preceding the
first Due Date following the Cut-off Date). In connection with such transfer and
assignment, the Depositor shall make a cash deposit to the Collection Account in
an amount equal to the Cash Deposit. The Depositor,  concurrently with execution
and delivery hereof,  does also hereby transfer,  assign, set over and otherwise
convey to the Trustee without  recourse  (except to the extent provided  herein)
all the right, title and interest of the Depositor in, to and under the Mortgage
Loan Purchase and Sale Agreement and, in, to and under each Originator  Purchase
Agreement as assignee of the Mortgage  Loan  Seller's  rights  thereunder to the
extent  related to any Mortgage  Loan.  The  Servicer,  Special  Servicer or the
Trustee  shall  notify the  Mortgage  Loan  Seller and the  Depositor  upon such
party's  becoming  aware of any  breach of the  representations  and  warranties
contained in this  Agreement or the Mortgage  Loan  Purchase and Sale  Agreement
that gives rise to a cure or repurchase obligation;  provided,  that the failure
of the Servicer, the Special Servicer or Trustee to give such notification shall
not  constitute a waiver of any cure or  repurchase  obligation.  The  Depositor
shall cause the Reserve Accounts, Cash Collateral Accounts and 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 Seller and the Originators.

     In connection with such transfer and assignment,  the Depositor does hereby
deliver to, and deposit with,  the  Custodian  (on behalf of the Trustee),  with
copies to the  Servicer and the Special  Servicer,  the  following  documents or
instruments with respect to each Mortgage Loan so assigned  (provided,  however,
the documents specified in item (ix) shall be delivered only to the Servicer):

        (i)     the original of the Note, endorsed without recourse to the order
                of the  Trustee  in the  following  form:  "Pay to the  order of
                LaSalle  National  Bank, as Trustee,  without  recourse",  or in
                blank, which Note and all endorsements thereon shall, unless the
                Mortgage  Loan was  originated  by the Mortgage  Loan Seller (as
                indicated on the Mortgage Loan Schedule),  show a complete chain
                of endorsement from the Originator to the Trustee;

        (ii)    the original  recorded  Mortgage or counterpart  thereof showing
                the  Originator as mortgagee  or, if any such original  Mortgage

                office, a copy thereof  certified to be a true and complete copy
                of the original thereof submitted for recording;

        (iii)   an  executed   Assignment  of  Mortgage  in  suitable  form  for
                recordation in the jurisdiction in which the Mortgaged  Property
                is  located to  "LaSalle  National  Bank,  as  Trustee,  without
                recourse";

        (iv)    if the related security agreement is separate from the Mortgage,

                suitable for filing, disclosing the assignment to the Trustee of
                the  security   interest  in  the  personal  property  (if  any)
                constituting security for repayment of the Mortgage Loan;

        (vi)    the  original  of the  Loan  Agreement  or  counterpart  thereof
                relating to such Mortgage Loan, if any;

                such instrument to the Trustee (a "Reassignment of Assignment of
                Leases,  Rents and Profits") in suitable form for recordation in
                the  jurisdiction  in which the  Mortgaged  Property  is located
                (which reassignment,  however, may be included in the Assignment
                of Mortgage and need not be a separate instrument);

        (ix)    copies of the original  Environmental  Reports of the  Mortgaged
                Properties made in connection  with  origination of the Mortgage
                Loans, if any;

        (x)     copies of the original  Management  Agreements,  if any, for the
                Mortgaged Property;

        (xii)   if the related  assignment  of  contracts  is separate  from the
                Mortgage,  the original  executed  version of such assignment of
                contracts and the assignment thereof to the Trustee;

        (xiii)  if any related Lock-Box  Agreement or Cash Collateral  Agreement
                is separate from the Mortgage or Loan Agreement, a copy thereof;
                with respect to the Reserve Accounts,  Cash Collateral  Accounts
                and  Lock-Box  Accounts,  if any, a copy of the UCC-1  financing
                statements,  if any,  submitted  for filing with  respect to the
                Mortgage  Loan  Seller's   security   interest  in  the  Reserve
                Accounts, Cash Collateral Accounts and Lock-Box Accounts and all
                funds  contained   therein  (and  UCC-3   financing   statements
                assigning such security interest to the Trustee on behalf of the
                Certificateholders);

        (xiv)   any and all  amendments,  modifications  and supplements to, and
                waivers related to, any of the foregoing;

        (xv)    with respect to the Westin GC Loan, the Westin GC  Participation
                Agreement; and

        (xvi)   any other written agreements related to the Mortgage Loan.

     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(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(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(viii) (if not otherwise  included
in the related  Assignment  of Mortgage)  which has not yet been  submitted  for
recordation;  and (2) prepare and file each UCC-2 or UCC-3  financing  statement
referred to in Section  2.01(v) or (xiii) which has not yet been  submitted  for
filing.  The Servicer shall upon delivery promptly prepare and 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  office,  each
such  document.  In the  event  that  any  such  document  is lost  or  returned
unrecorded  because of a defect  therein,  the  Servicer,  at the expense of the
Depositor,  shall use its best efforts to promptly prepare a substitute document
for signature by the  Depositor,  and  thereafter  the Servicer shall cause each
such document to be duly recorded.  The Servicer shall, promptly upon 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(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.

     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. The Trustee agrees to review each Mortgage File within
45 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 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(iv),  (v), (vi), (vii) (in the case of any
endorsement  thereto),  (viii) and (x)  through  (xv),  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  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 Mortgage Loan Seller to, repurchase the related Mortgage Loan in
the manner provided in Section 2.03. None of the Servicer,  the Special Servicer
and 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

                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

        (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

                        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

                        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

                        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

        (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,  the Note and the Mortgage  were
                                not subject to an assignment or pledge,  and 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)   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;

                        (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 Seller  contained in the Mortgage
                                Loan  Purchase and Sale  Agreement  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

                                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 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
Seller in the  Mortgage  Loan  Purchase and Sale  Agreement  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 Mortgage Loan Seller and the Mortgage Loan Seller
shall, to the extent the Mortgage Loan Seller is obligated to cure or repurchase
the related Mortgage Loan under the terms of the 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 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 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  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  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,  that in the event
the Mortgage Loan Seller fails to cure such breach within such additional 90-day
period,  the  Repurchase  Price shall  include  interest on any Advances made in
respect of the related Mortgage Loan during such period.

     (f) Upon receipt by the Servicer from the Depositor or 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
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  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 the Mortgage Loan Seller 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 the  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,  the 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  the  Mortgage  Loan Seller in  recovering,  from the
related Borrower the amount of any such expenses.

     (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 Seller or the  Depositor  fails to
fulfill its  obligations  under this  Section  2.03 with respect to any Mortgage
Loan, the 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.

     (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 the Mortgage Loan Seller  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 the  Mortgage  Loan  Seller  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 the  Mortgage  Loan  Seller  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 the Mortgage Loan Seller.

        (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 the Mortgage Loan Seller 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   does   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 Seller nor NSI
                finances  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
                Seller or NSI; provided,  however, that the Mortgage Loan Seller
                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,
                the Mortgage  Loan Seller 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 Seller or NSI for any such expenses or liabilities
                paid  by the  Mortgage  Loan  Seller  or NSI on the  Depositor's
                behalf.  To facilitate the  registration  process,  the Mortgage
                Loan Seller  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 the Mortgage
                Loan Seller and/or NSI these expenses on an allocable  basis out
                of the proceeds of mortgage pass-through  transactions.  Neither
                the  Mortgage  Loan  Seller  nor NSI has funded or will fund the
                Depositor's  operating expenses.  The assets or creditworthiness
                of the Mortgage Loan Seller,  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  Seller,  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 Seller 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  Seller or NSI, as being  available  for the
                payment of the  liabilities  or obligations of the Mortgage Loan
                Seller,   NSI  or  any  of  their  affiliates.   The  assets  or
                creditworthiness  of the  Mortgage  Loan  Seller,  NSI or any of
                their affiliates are not held out by the Mortgage Loan Seller or
                NSI, to the knowledge of the  Depositor,  and the Depositor will
                not permit that the assets or  creditworthiness  of the Mortgage
                Loan Seller or NSI will be held out by the Mortgage  Loan Seller
                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 Seller or NSI,  and the  Depositor  will not
                permit that its separate corporate existence will be used by the
                Mortgage Loan Seller 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 the  Mortgage  Loan Seller 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 the
                Mortgage Loan Seller or an affiliate of NSI. To the knowledge of
                the  Depositor,  the  Mortgage  Loan  Seller's  existence is not
                dependent  on  the  Depositor  being  its  subsidiary  and it is
                expected that the Mortgage Loan Seller 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
                Seller's  existence is not dependent on the Depositor  being its
                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 Seller,  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  Seller,  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 Seller,
                NSI and  any of  their  affiliates,  and its  other  assets  are
                separately  identifiable and distinguishable  from the assets of
                the Mortgage Loan Seller, 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 Seller 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 Seller or
                NSI,  if the  Mortgage  Loan  Seller  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 Seller,  NSI or any of their
                affiliates   unless  the  respective   Boards  of  Directors  or
                officers, as appropriate, of the Depositor and the Mortgage Loan
                Seller or NSI, if the Mortgage Loan Seller 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  Seller  to the  Depositor  pursuant  to the
                Mortgage  Loan  Purchase and Sale  Agreement 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 the
                Pooling   and   Servicing   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  the  Pooling  and  Servicing
                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 Seller.

        (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 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 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; 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  Servicer  of  or  compliance  by  the  Servicer  with  this
                Agreement, or if required, such approval has been obtained prior
                to the Cut-off Date.

     (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 corporation,  duly organized,  validly

                Texas and has all 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 Special Servicer, it is
                not required to become  licensed for such  purposes with respect
                to the Cayman Islands,  but the Special Servicer shall become so
                licensed if so required;

        (ii)    The Special Servicer has the full corporate power, authority and
                legal right to execute and deliver this Agreement and to perform

                Agreement  by the  Special  Servicer  and  its  performance  and
                compliance with the terms of this Agreement will not violate the
                Special  Servicer's  charter or by-laws 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

                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,  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 Seller.

     (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.

Lower-Tier Regular Interests.

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

860G(a)(9) of the Code.  The "latest  possible  maturity date" of the Lower-Tier
Regular  Interests  and  the  Regular   Certificates  for  purposes  of  Section
860G(a)(1) of the Code is the Scheduled  Final  Distribution  Date.  The initial
Certificate  Balance of each 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 (other than the Class A-8Z-L Interest
and the Class  B-3SC-L  Interest)  is a per  annum  rate  equal to the  Weighted
Average Net Mortgage  Pass-Through  Rate. The interest rate for the Class A-8Z-L
Interest is the Mortgage  Pass-Through Rate on the Comsat Junior Loan. The Class
B-3SC-L  Interest has no interest rate and is not entitled to  distributions  of
interest.

     (b) The Class V-1  Certificates  represent  pro rata  undivided  beneficial
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.

     (c) None of the Depositor,  the Trustee, the Servicer,  the Fiscal Agent or
the Special  Servicer  shall enter into any  arrangement by which the Trust Fund
will receive a fee or other compensation for services other than as specifically
contemplated herein.

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS


     SECTION 3.01.  Servicer to Act as Servicer;  Administration of the Mortgage
Loans.

     (a)  The  Servicer  and  the  Special  Servicer,  each  as  an  independent
contractor  servicer,  shall service and administer the Mortgage Loans on behalf
of the  Trust  Fund and the  Trustee  (as  trustee  for  Certificateholders)  in
accordance with the Servicing Standard.

     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.  Notwithstanding the
foregoing,  neither the Servicer nor the Special  Servicer shall modify,  amend,
waive or  otherwise  consent  to any  change of the terms of any  Mortgage  Loan
except under the  circumstances  described in Sections 3.09, 3.10, 3.28 and 3.30
or the definition of Minimum Defaulted Monthly Payment hereof.  The Servicer and
Special  Servicer  shall service and administer the Mortgage Loans in accordance
with  applicable law and shall provide to the Borrowers any reports  required to
be provided to them thereby.  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  and  (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.  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,  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.

     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 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.  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, 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 Asset
Securitization  Corporation,   Commercial  Mortgage  Pass-Through  Certificates,
Series 1997-D5,  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 and any Class A-8Z
                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, Class A-8Z Available Funds and Class B-3SC 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.

     (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

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.

        (ii)    to pay or reimburse the Trustee,  the Fiscal Agent, the Servicer

                Trustee 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

                particular  Mortgage  Loan or REO Property with respect to which

                Advances,  any Subordinate Class Advance Amounts with respect to
                the related Distribution Date as provided in 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

                Advance  Interest Amount relating to P&I Advances and (B) to pay
                to the Servicer,  Special Servicer,  Trustee or Fiscal Agent any
                Advance  Interest  Amounts  not  relating  to any  P&I  Advances
                (provided,  however, that payment of Advance Interest Amounts in
                respect  of Class  A-8Z P&I  Advances  shall be  limited  to any
                collections  on or in  respect of the Comsat  Junior  Loan,  and
                payment of Advance  Interest  Amounts in respect of Class  B-3SC
                Advances shall be limited to any collections on or in respect of
                the Saul  Centers  Retail  Pool Loan in excess of the  Senior SC
                Distribution  Amount,  and collections on the Comsat Junior Loan
                and the SC Junior  Portion of the Saul Centers  Retail Pool Loan
                shall be  unavailable  with respect to advances other than Class
                A-8Z P&I  Advances  and Class  B-3SC  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);

                Special  Servicing  Compensation  (if  any),  respectively,   in
                respect of the immediately  preceding  month, to be paid, in the
                case of the Servicing Fee, from interest received on the related

                Servicer may rely on a certification  of the Special Servicer as

                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

                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),

                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  pay  to  the   participant  or   participants   (the  "Other
                Participant")  in the  Westin GC  Participation,  other than the
                Trustee  as  assignee  of the  Depositor  under  the  Westin  GC
                Participation  Agreement, the amount of any payment to which the
                Other  Participant is entitled under the Westin GC Participation
                Agreement;

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

        (xi)    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 (ii)-(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,   Nomura  Asset  Capital
Corporation)  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 Nomura Asset Capital Corporation, 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 Nomura Asset  Capital  Corporation,  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,  Nomura  Asset
Capital Corporation,  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 Nomura
Asset Capital Corporation,  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 Nomura Asset Capital Corporation, 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 Nomura
                Asset Capital  Corporation,  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 Nomura Asset  Capital  Corporation)  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 Nomura Asset Capital  Corporation  pursuant to
written  instructions.  The Servicer  (or with  respect to any REO Account,  the
Special Servicer, or with respect to the Interest Reserve Account,  Nomura Asset
Capital  Corporation)  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 Nomura Asset Capital Corporation, 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  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.


     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 18
months  (or such  longer  period or with such  extended  period  endorsement  as
provided in the related  Mortgage or other loan document) of rent  interruptions
and (iii) such other insurance as is required in the related  Mortgage Loan. 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,  the
Servicer will use its 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  Kmart  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.

     Any  determination  made by the Servicer or Special Servicer that insurance
is not  commercially  reasonably  available  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.

     (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  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  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,  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,  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.
    

     (b)  If  any  Mortgage  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 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.

     (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 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 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. 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  Certificateholders  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  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  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 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 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 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 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

the Trustee's responsibilities and obligations under this Agreement.

     Except as otherwise  provided  herein,  the Servicer shall pay all expenses
incurred by it in connection with its servicing activities hereunder,  including
all fees of any  sub-servicers  retained  by it.  Except as  otherwise  provided
herein, the Trustee shall pay all expenses incurred by it in connection with its

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, loan service  transaction  fees,  demand fees,
statement  charges and other fees  relating to any Specially  Serviced  Mortgage
Loan or with respect to servicing  activities  performed by the Special Servicer
and, for any modification, extension or other action by the Special Servicer for
which the consent of, or review by, the  Servicer is  required,  one-half 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.  If a review  by, or the  consent  of,  the  Servicer  is not
required in connection  with an  extension,  modification  or other action,  the
Special  Servicer  shall be  entitled  to the full  amount of any  modification,
extension or other fees.

     Except as otherwise  provided  herein,  the Special  Servicer shall pay all
expenses incurred by it in connection with its servicing activities hereunder.

     (c)  In  addition  to the  Special  Servicing  Fees  provided  for in  this
Agreement,  and not in lieu thereof,  the Special  Servicer shall be entitled to
the Principal  Recovery Fee; provided,  however,  that no Principal Recovery Fee
will be payable in connection  with, or out of  Liquidation  Proceeds  resulting
from, the purchase of any Specially  Serviced  Mortgage Loan (i) by the Mortgage
Loan Seller  pursuant  to any  repurchase  obligation  under the  Mortgage  Loan
Purchase and Sale Agreement or by the Originators  pursuant to their obligations
under the Original Purchase Agreements or (ii) by the Servicer, the Depositor or
Certificateholders pursuant to Section 9.01.

     (d) Notwithstanding  the foregoing,  in the event that the Special Servicer
is, or is an  Affiliate  of, or has an economic  arrangement  for the purpose of
retaining  the full Special  Servicing  Fee Rate with,  the Holder or Holders of
Certificates  representing  greater than 50% of the Percentage  Interests of the
most subordinate Class of Certificates  then  outstanding,  the Special Servicer
shall provide  written notice  thereof to the Servicer and the Special  Servicer
shall be  entitled  to receive a Special  Servicing  Fee that  accrues at a rate
equal to one-half of the Special Servicing Fee Rate.

     (e) The  Servicer,  Special  Servicer  and  Trustee  shall be  entitled  to
reimbursement from the Trust Fund for the costs and expenses incurred by them in
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).

     (f) 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.

prior to the related  Servicer  Remittance  Date in the form required by Section
3.13(f)  or shall be  provided  by means of such  reports  so  delivered  by the

manifest  error,  the  Servicer  shall be  entitled to  conclusively  rely upon,
without investigation or inquiry, the information and reports delivered to it by
the Special  Servicer,  and the Trustee shall be entitled to  conclusively  rely

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

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

     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

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
or having a current  trailing  twelve-month  Debt Service Coverage Ratio that is
less than 1.00x, (ii) Mortgage Loans as to which any required  inspection of the
related Mortgaged  Property  conducted by the Servicer  indicates a problem that
the Servicer  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)

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

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 and
S&P and,  upon the request of any of the  Trustee,  the  Depositor  or any other

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 ten
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.

March 15 of each year,  beginning with March 15, 1998, an Officer's  Certificate
stating,  as to each signatory  thereof,  (i) that a review of the activities of
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  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,  1998,  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
the original Accountant's Statement.


     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,
the FDIC and the OTS and the supervisory agents and examiners of such boards and
such  corporations,  and  any  other  governmental  or  regulatory  body  to the
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 Asset Securitization  Corporation,  Commercial Mortgage  Pass-Through
Certificates,  Series  1997-D5,  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. 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  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 thirty  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  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
in accordance with MAI standards 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 send 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 Section
3.10, the Special Servicer shall deliver to the Trustee an Officers' Certificate
to the effect that pursuant to Section 3.10, 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 the  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 (at
its own expense) 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 December 1997 (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  1.0 or  (iii) is  delinquent  for 60  days,  each  related
Mortgaged  Property  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.

     (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, Moody's and S&P and (iii) otherwise satisfies
any criteria set forth in the Mortgage and related documents.

     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 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 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.

     SECTION 3.22. Reports to the Securities and Exchange Commission;  Available
Information.

     (a) The Servicer  shall prepare and sign, on behalf of the  Depositor,  any
and all Exchange Act Reports;  provided,  however,  that (i) the Depositor shall

Trust Fund and (ii) the Special Servicer shall prepare and sign on behalf of the
Depositor  any Exchange Act Report which  includes an Annual  Compliance  Report
relating to the Special  Servicer.  Each  Exchange  Act Report  consisting  of a

Delinquent Loan Status Report,  Historical Loss Estimate Report, Historical Loan
Modification  Report,  REO Status  Report,  Operating  Statement  Analysis,  NOI

consisting  of an Annual  Compliance  Report shall be prepared as exhibits to an
Annual Report on Form 10-K and shall identify the aggregate number of Holders of
Public  Certificates  and  Direct  Participants   holding  positions  in  Public
Certificates as of December 31 (or the nearest  Business Day if such date is not

such report,  which  version  shall be prepared as a Microsoft  Word for Windows
file (or in such other format as the Trustee,  the Depositor and the Servicer or
the Special Servicer may agree),  provided, that, with respect to the electronic
version of each Exchange Act Report  consisting of a monthly  Distribution  Date
Statement,  the Servicer need only deliver an electronic  version of the related
Form 8-K and the  Trustee  shall  attach an  electronic  version of the  related
monthly Distribution Date Statement thereto as an exhibit.  Exchange Act Reports
consisting of (i) a monthly  Distribution  Date Statement  shall be filed within

delivered  to the  Trustee  on a  computer  diskette  (delivered  by  courier in
packaging  designed to shield such diskette from damage in  transmission)  or by
means of electronic data transfer system mutually agreed upon by the Trustee and
the Servicer or Special  Servicer.  The Trustee  shall forward each Exchange Act
Report to the  Depositor in a manner and in a format  agreed upon by the Trustee
and the Depositor.  Manually-signed  copies of each Exchange Act Report shall be
delivered  to the  Depositor to the  attention of William  Kramer (or such other
Persons  as are  designated  in writing  by the  Depositor),  with a copy to the
Trustee.

     If  information  for any Exchange Act Report is  incomplete  by the date on
which such report is required to be filed under the  Exchange  Act, the Servicer
or,  with  respect to any  Annual  Compliance  Report  relating  to the  Special
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
for forwarding to the Depositor as provided  above.  The Servicer or the Special
Servicer, as applicable,  shall deliver the related report in electronic form to
the Trustee when such  information is available and such completed  report shall
be forwarded electronically by the Trustee to the Depositor.

     None of the Servicer, the Special Servicer and the Trustee shall (i) file a
Form ID with  respect  to the  Depositor  or (ii)  cause the Trust  Fund to stop
filing reports,  statements and information with the Commission pursuant to this
Section unless directed to do so by the Depositor or the continued  reporting is
prohibited  under  the  Exchange  Act or any  regulations  thereunder.  Upon the
written request of the Depositor,  the Servicer shall file a Form 15 relating to
the Trust Fund with the  Commission  and send a copy  thereof to the Trustee and
the Depositor.

     The Trustee shall, at the written  direction of the Depositor,  solicit any
and all proxies of the Certificateholders  whenever such proxies are required to
be solicited pursuant to the Exchange Act.

     (b) [Intentionally left blank].

     (c) The  Servicer  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 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  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) [Intentionally left blank].

     The Servicer and the Special  Servicer  shall make available at its offices
during normal business hours, or send to the requesting  party at the expense of
each such  requesting  party (other than the Rating  Agencies and the Depositor)
for  review  by  the  Depositor,   the  Trustee,   the  Rating   Agencies,   any
Certificateholder,  any  Person  identified  to  the  Servicer  or  the  Special
Servicer, as applicable, by a Certificateholder as a prospective transferee of a
Certificate and any other Persons to whom the Servicer or the Special  Servicer,
as applicable,  believes such disclosure to be appropriate the following  items:
(i) all financial statements,  occupancy  information,  rent rolls, retail sales
information,  average daily room rates and similar  information  received by the
Servicer or the Special Servicer,  as applicable,  from each Borrower,  (ii) the
inspection  reports  prepared  by or on behalf of the  Servicer  or the  Special

terms of a Mortgage  Loan entered into by the Servicer or the Special  Servicer,
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
of the Servicer,  the Special  Servicer and the Trustee shall be indemnified and
held harmless by the Trust Fund against any loss,  liability or expense incurred
in  connection  with any legal action  relating to any  statement or omission or
alleged statement or omission therein. None of the Trustee, the Special Servicer
and the Servicer shall have any  responsibility or liability with respect to any
Exchange  Act  Report  filed by the  Depositor,  and each of the  Servicer,  the
Special  Servicer and the Trustee shall be indemnified  and held harmless by the
Trust Fund against any loss,  liability or expense  incurred in connection  with
any legal action  relating to any statement or omission or alleged  statement or
omission therein.


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

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

     The Servicer  shall  administer  each  Lock-Box  Account,  Cash  Collateral
Account,  Escrow  Account and  Reserve  Account in  accordance  with the related
Mortgage  or Loan  Agreement,  Cash  Collateral  Account  Agreement  or Lock-Box
Agreement, if any.

     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) AMRESCO  Management,  Inc. 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  appointment,  in and of itself,  would not
have caused 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.  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 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,
a written statement  describing,  on a Mortgage Loan by Mortgage Loan basis, (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.

     (e) The Servicer  shall  furnish to the Special  Servicer a current copy of
any "watch list" that it maintains with respect to the Mortgage Loans.

     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  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 Mortgage 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
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  or to  amend  or  modify  the  related  Borrower's  organizational
documents,  then the Special Servicer may only consent to either such action, or
grant a waiver with respect  thereto,  if the Special  Servicer  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 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. The Servicer shall not be entitled
or required to consent to, or grant a waiver with respect to, either action.

     (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 Nomura Asset  Capital
Corporation  and  shall  promptly  notify  and send such  bills to Nomura  Asset
Capital Corporation,  Attention: Sheryl McAfee. Nomura Asset Capital Corporation
will notify each Rating Agency to bill Nomura Asset Capital Corporation for such
services  and  to  send  such  bills  to  the  Servicer.  Nomura  Asset  Capital
Corporation  will pay such  portion of the bill not paid from funds  provided by
the  applicable  Borrowers  (as  described in this section (c)) and the Servicer
shall notify Nomura Asset Capital  Corporation,  of the portion of the bill that
it has paid from funds collected from such Borrowers.  In the event that for any
reason  Nomura Asset  Capital  Corporation  shall fail to pay any Rating  Agency
monitoring  or  review  fee as  required  by  this  section,  Nomura  Securities
International, Inc. shall pay such fee.

     (d) With respect to all Mortgage  Loans that provide that the holder of the
related Note may apply the monthly payment against  principal,  interest and any
other sums due in the order as the holder shall  determine,  the Servicer  shall
apply such Monthly  Payment to interest  (other than Excess  Interest or Default
Interest)  under the related  Mortgage Loan prior to application to principal or
any other sums due.

     (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,  the
Servicer shall not consent to a change of franchise  affiliation with respect to
a Mortgaged Property unless it obtains written  confirmation from Fitch, 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 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(i).

     (h)  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.

     (i) 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.

     (j) Each of the  Servicer  and the Special  Servicer  hereby  agrees to use
reasonable  best  efforts  to abide by the terms  and  conditions  precedent  to
payment of claims under any Lease  Enhancement  Policies and to use best efforts
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,  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 reasonable best efforts to take any and
all actions required under the Lease  Enhancement  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 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 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. Any
and all amounts collected under a Lease Enhancement  Policy shall be immediately
deposited in the Collection Account, subject to withdrawal as provided herein.

     (k) With respect to the Saul Centers  Retail Pool Loan,  the Servicer shall
not declare a default thereunder for the failure of the related Borrower to make
a required Monthly Payment so long as such Borrower pays an amount in respect of
such Monthly  Payment at least equal to the Minimum SC Senior  Monthly  Payment.
With respect to the Comsat  Junior Loan,  the  Servicer  shall not  foreclose or
otherwise  exercise  remedies  available to the Servicer  thereunder  unless the
Comsat Senior Loan is also in default or has been paid in full.

     (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 (i) the prior written consent of the Servicer (which
consent will be given or withheld in accordance with the Servicing  Standard) or
(ii) the affirmative vote in favor of such prepayment from 66 2/3% of the Voting
Rights  of all  Certificateholders  or 66  2/3%  of  the  Voting  Rights  of all
Certificateholders  responding  within 20 Business Days of being given notice by
the Trustee of such  proposed  action.  Upon the written  request of the Special
Servicer,  the  Trustee  shall  forward  Certificateholders  any  request of the
Special  Servicer  for  the  vote  of the  Certificateholders  pursuant  to this
Section.

     (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  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)  Servicer   shall   promptly   provide  notice  to  the  "licensor"  or
"franchisor"  with respect to the Mortgaged  Properties that are Holiday Inns or
Westin Hotels to the effect that the related  Mortgage Loan has been assigned to
the  Trust  Fund.  In so doing,  Servicer  shall  include  in such  notices  the
information specified in the related "comfort" or "estoppel" letters executed by
the related "licensor or "franchisor".  Trustee shall cooperate with Servicer in
furnishing any information required to be included in such notices.

     (o) 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  Servicer's   affiliates   engaged  in  the  commercial   mortgage
origination business.

     (p) On each Servicer  Remittance  Date, the Servicer shall withdraw (to the
extent  received) from the Collection  Account an amount equal to the product of
(i) the  "Participation  Percentage" (as defined in the Westin GC  Participation
Agreement) and (ii) the amount of each Monthly Payment on the Westin GC Loan and
remit such amount to the Other Participant on the following Distribution Date as
provided in the Westin GC  Participation  Agreement.  Nothing in this  Agreement
shall be  deemed to  override  the  provisions  of the  Westin GC  Participation
Agreement  with  respect  to the  rights  of the Other  Participant  thereunder,
including  the rights of the Other  Participant  with  respect to its  allocable
share of any Net Liquidation Proceeds, Insurance Proceeds or condemnation award.
The Servicer and the Special Servicer, as applicable,  shall exercise the rights
of the "Lead Lender" under the Westin GC  Participation  Agreement in accordance
with the Servicing  Standard and shall act with respect to the Westin GC Loan as
if such loan were a Mortgage Loan hereunder  provided that, for purposes hereof,
Monthly Payments,  P&I Advances and Assumed Scheduled  Payments shall refer only
to the portion of the Westin GC Loan other than the  "Participation  Percentage"
(as  defined in the Westin GC  Participation  Agreement)  of such  amounts  with
respect to the Westin GC Loan.

     (q) With  respect to each Kmart Loan,  the  Servicer  shall,  to the extent
permitted under the related Mortgage Loan Documents, accelerate all indebtedness
thereunder prior to making any claim under the related casualty and condemnation
lease enhancement insurance policy.

     (r) 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  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(r) 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.

     (s) 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.

     (t) 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.

     (u) 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.

     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  collateral or
          release  mortgagors  or  guarantors  except as  provided in clause (v)
          below;

     (v)  the Special  Servicer may only allow a substitution  of collateral and
          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 of
          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  (determined  as  provided  in the
preceding  sentence)  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.  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 paragraph  (d) 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:

     (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 Servicer
shall  withdraw  from the  Collateral  Account and 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 (d) 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 five Business Days
prior to the Servicer  Remittance Date of the amount of distributions to be made
to 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 the clause (a) or (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) or (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.

                       DISTRIBUTIONS TO CERTIFICATEHOLDERS

     SECTION 4.01. Distributions.

     (a) On each  Distribution  Date,  amounts held in the Distribution  Account
shall be withdrawn (to the extent of Available Funds, in the case of all Classes
of Lower-Tier  Regular  Interests  other than the Class A-8Z-L  Interest and the
Class B-3SC-L Interest; to the extent of Class A-8Z Available Funds, in the case
of the Class A-8Z-L Interest;  and to the extent of Class B-3SC Available Funds,
in the case of the Class B-3SC-L  Interest) and  distributed  on the  Lower-Tier
REMIC 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,  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-1D, Class
          A-1E,  Class A-2,  Class A-3,  Class A-4,  Class A-5, Class A-6, Class
          A-7,  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.  The  Class  A-8Z-L
          Interest will accrue  interest,  and its  Certificate  Balance will be
          increased,  at the same time and in the same amounts as the Class A-8Z
          Certificates.  The  Certificate  Balance of each  Class of  Lower-Tier
          Regular Interests shall at all times equal the Certificate  Balance of
          its Related Class of Certificates.

     (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.  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.

     (iv) Any amounts remaining in the Lower-Tier 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 (other than such amounts in
respect  of  amounts  distributed  on the Class  A-8Z-L  Interest  and the Class
B-3SC-L  Interest   pursuant  to  Section   4.01(a),   which  such  amounts  are
distributable pursuant to Sections 4.01(d)(i) and 4.01(d)(ii),  respectively) in

                    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).

               (VI) Sixth,  to the Class A-1D  Certificates,  an amount equal to
                    (A) the present value  (discounted  at the Discount Rate for
                    the Class A-1D  Certificates  plus the  Spread  Rate for the
                    Class A-1D  Certificates)  of the  aggregate  principal  and
                    interest  that  would have been paid in respect of the Class
                    A-1D  Certificates  from the Distribution  Date occurring in
                    the  following  month until the  Certificate  Balance of the
                    Class A-1D 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-1D   Certificates   and  (C)  the   present   value
                    (discounted   at  the  Discount  Rate  for  the  Class  A-1D
                    Certificates  plus  the  Spread  Rate  for  the  Class  A-1D
                    Certificates)  of the aggregate  principal and interest that
                    will be paid in respect of the Class A-1D  Certificates from
                    the Distribution Date occurring in the following month until
                    the  Certificate  Balance of the Class A-1D  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) 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 Class A-1A-L Interest shall receive distributions in respect of
Prepayment   Premiums   distributable   to  the  Class  A-1A  and  Class   A-CS1
Certificates,  the Class A-1B-L Interest shall receive  distributions in respect
of Prepayment Premiums  distributable to the Class A-1B Certificates,  the Class

respect of Prepayment Premiums distributable to the Class PS-1 Certificates, the
Class A-8Z-L  Interest  shall  receive  distributions  in respect of  Prepayment
Premiums  distributable  to the Class A-8Z  Certificates,  and the Class  B-7H-L
Interest  shall  receive   distributions  in  respect  of  Prepayment   Premiums
distributable  to the Class  B-7H  Certificates,  in each case from  amounts  on
deposit in the  Distribution  Account.  The Class A-1A-L,  Class  A-1B-L,  Class
A-1C-L,  Class A-1D-L, Class A-2-L, Class A-8Z-L, Class B-3SC-L and Class B-7H-L
Interests shall be entitled to receive distributions of such Prepayment Premiums
regardless of whether their respective Certificate Balances have been reduced to
zero.
    
     (d) (i) On each Distribution  Date,  Holders of the Class A-8Z Certificates
shall receive  distributions  from amounts (if any) on deposit in the Upper-Tier
Distribution  Account  in respect of  amounts  distributed  on the Class  A-8Z-L
Interest,  in respect of principal (including  accretions to principal resulting
from the capitalization of interest) in the amounts and in the order of priority
set forth below:

                           (A)      First,  to the Class A-8Z  Certificates,  in
                                    reduction   of   the   Certificate   Balance
                                    thereof,    the   Class    A-8Z    Principal
                                    Distribution  Amount,  until the Certificate
                                    Balance thereof is reduced to zero;

                           (B)      Second, to the Class A-8Z Certificates,  for
                                    the  unreimbursed   amounts  of  Class  A-8Z
                                    Realized  Losses,  if any,  up to an  amount
                                    equal   to   the   Class   A-8Z    Principal
                                    Distribution  Amount less  portions  thereof
                                    distributed   on  such   Distribution   Date
                                    pursuant  to any  prior  clause,  an  amount
                                    equal to the aggregate of such  unreimbursed
                                    Class  A-8Z   Realized   Losses   previously
                                    allocated thereto; and

                           (C)      Third, to the Class R Certificates, but only
                                    to the  extent of any Class  A-8Z  Available
                                    Funds    remaining    in   the    Upper-Tier
                                    Distribution Account.

     On each Distribution  Date,  Holders of the Class A-8Z  Certificates  shall
receive distributions of principal in an amount equal to the aggregate amount of
principal  distributed to the Class A-8Z-L Interest and the Certificate  Balance
of the  Class  A-8Z  Certificates  will  be  reduced  in  accordance  with  such
distributions  of principal and by the allocation of Class A-8Z Realized  Losses
to such Class.


          (ii)  On  each   Distribution   Date,   Holders  of  the  Class  B-3SC
Certificates  shall  receive  distributions  from  amounts  on  deposit  in  the
Upper-Tier  Distribution  Account in respect of amounts distributed on the Class
B-3SC-L  Interest,  in respect of  principal  in the amounts and in the order of
priority set forth below:

                           (A)      First, to the Class B-3SC  Certificates,  in
                                    reduction   of   the   Certificate   Balance
                                    thereof,    the   Class   B-3SC    Principal
                                    Distribution  Amount,  until the Certificate
                                    Balance thereof is reduced to zero;

                           (B)      Second, to the Class B-3SC Certificates, for
                                    the  unreimbursed  amounts  of  Class  B-3SC
                                    Realized  Losses,  if any,  up to an  amount
                                    equal   to   the   Class   B-3SC   Principal
                                    Distribution  Amount less  portions  thereof
                                    distributed   on  such   Distribution   Date
                                    pursuant  to any  prior  clause,  an  amount
                                    equal to the aggregate of such  unreimbursed
                                    Class  B-3SC  Realized   Losses   previously
                                    allocated   to   such   Lower-Tier   Regular
                                    Interest; and

                           (C)      Third, to the Class R Certificates, but only
                                    to the extent of any Class  B-3SC  Available
                                    Funds    remaining    in   the    Upper-Tier
                                    Distribution Account.

     On each Distribution  Date,  Holders of the Class B-3SC  Certificates shall
receive distributions of principal in an amount equal to the aggregate amount of
principal distributed to the Class B-3SC-L Interest, and the Certificate Balance
of the  Class  B-3SC  Certificates  will be  reduced  in  accordance  with  such
distributions  of principal and by the allocation of Class B-3SC Realized Losses
to such Class.

          (iii)  On each  Distribution  Date,  Net  Default  Interest  for  such
Distribution Date shall be distributed to the Class V-1 Certificates.

          (iv) On any applicable  Distribution  Date,  Excess  Interest for such
Distribution Date shall be distributed to the Class V-2 Certificates.

     (e) The Certificate  Balances of each Class of Regular  Certificates (other
than the Class A-8Z, Class B-3SC,  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 (other than those  attributable to the Comsat Junior Loan or
the SC Junior  Portion of the Saul Centers  Retail Pool Loan) 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-7  Certificates;  ninth, to the Class A-6
Certificates;  tenth, to the Class A-5 Certificates;  eleventh, to the Class A-4
Certificates;  twelfth, to the Class A-3 Certificates;  thirteenth, to the Class
A-2 Certificates;  fourteenth,  to the Class A-1E Certificates,  and finally, to
the Class A-1A,  Class A-1B, Class A-1C and Class A-1D  Certificates,  pro rata,
based on their respective Certificate Balances. 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.  The Certificate Balance of the Class A-8Z Certificates
will be reduced without  distribution on any Distribution Date as a write-off to
the extent of any Class A-8Z  Realized  Losses  with  respect to such date.  The
Class A-8Z  Certificates  will only be  entitled to  recoveries  from the Comsat
Junior Loan. The  Certificate  Balance of the Class B-3SC  Certificates  will be
reduced  without  distribution  on any  Distribution  Date as a write-off to the
extent of any Class B-3SC  Realized  Losses with respect to such date. The Class
B-3SC  Certificates  will only be entitled to  recoveries  from the Saul Centers
Retail Pool Loan, to the extent  available  after  application  to the SC Senior
Portion.  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, including without limitation by allocation to the Class A-8Z
Certificates  if due to the Comsat Junior Loan, to the Class B-3SC  Certificates
if due to the SC Junior Portion of the Saul Centers Retail Pool Loan, and to the
other Certificates if due to other Mortgage Loans.

     Realized Losses and such other amounts described above which are applied to
each Class of Certificates  will be allocated to reduce the Certificate  Balance
of the Related Lower-Tier Regular Interests.

     (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 holds  Certificates with
an aggregate initial Certificate Balance in excess of $5,000,000, and 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) On or after any  Distribution  Date on which the Class B-6 Certificates
are the most  subordinate  class of  Certificates  outstanding,  the Certificate
Balances of the Class B-6,  Class B-5,  Class B-4,  Class B-3,  Class B-2, Class
B-1,  Class A-7, Class A-6, Class A-5, Class A-4, Class A-3, Class A-2 and Class
A-1E  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-6,  Class B-5,  Class B-4,  Class B-3,  Class B-2, Class B-1, Class A-7,
Class  A-6,  Class  A-5,  Class  A-4,  Class  A-3,  Class  A-2  and  Class  A-1E
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-6
Certificates,  second,  to the Class B-5  Certificates,  third, to the Class B-4
Certificates,  fourth,  to the Class B-3  Certificates,  fifth, to the Class B-2
Certificates,  sixth, to the Class B-1 Certificates,  seventh,  to the Class A-7
Certificates,  eighth,  to the Class A-6  Certificates,  ninth, to the Class A-5
Certificates,  tenth to the Class  A-4  Certificate,  eleventh  to the Class A-3
Certificates,  twelfth, to the Class A-2 Certificates, and finally, to the Class
A-1E 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.  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 unanticipated  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.  Unanticipated  indemnification  expenses  which are  applied to each
Class of  Certificates  shall be  allocated  to the Related  Lower-Tier  Regular
Interests.

     Prepayment  Interest  Shortfalls in excess of Servicer  Prepayment Interest
Shortfalls   shall  be  allocated  prior  to  the  allocation  of  unanticipated
indemnification expenses.

shall contain substantially the categories of information regarding the Mortgage
Loans set forth in the Prospectus under the caption "Description of the Mortgage
Pool--Certain  Terms and Conditions of the Mortgage  Loans"  (calculated,  where
applicable, on the basis of the most recent relevant information provided by the
Borrowers  to the Servicer or the Special  Servicer,  as the case may be, and by
the Servicer or the Special Servicer, as the case may be, to the Trustee), which
shall also include a loan-by-loan  listing (in descending balance order) showing
loan name,  property type,  location,  unpaid principal balance,  Mortgage Rate,
paid through date,  maturity date, net interest  portion of the Monthly Payment,
principal portion of the Monthly Payment and any Prepayment Premium. Such report
shall be made available electronically; provided, however, that the Trustee will
provide  Certificateholders  with a written  copy of such  report  upon  written
request.

     (c) On each Distribution  Date, the Trustee shall deliver or shall cause to
be delivered  by first class mail to each  Certificateholder,  each  prospective

Depositor,  each  Underwriter  and each Rating Agency a copy of the  Comparative
Financial Status Report,  the Delinquent Loan Status Report, the Historical Loss

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 January 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 loan
file and CSSA  property  file,  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 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 Special Servicer,  either Rating Agency,  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 by the terms of any of the
Mortgage  Documents):  (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 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 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  or Unitholder  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  4.05(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),  Class A-8Z Available Funds (other than Class A-8Z
               P&I Advances) and Class B-3SC  Available  Funds (other than Class
               B-3SC Advances) and Subordinate Class Advance Recoveries for such
               Distribution Date; and

          (iii)make a P&I  Advance,  Class  A-8Z  P&I  Advance  or  Class  B-3SC
               Advance,  as  applicable,  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 (and therefore are
               not included in the remittance  described in the preceding clause
               (ii)).

     (c) Notwithstanding anything to the contrary contained in Section 4.06, any
P&I Advance with  respect to the Saul Centers  Retail Pool Loan shall not exceed
the Minimum SC Senior Monthly  Payment.  No Class A-8Z P&I Advance shall be made
until  after the Class  A-8Z  Scheduled  Distribution  Date and then only if the
Balloon  Payment due on the Maturity Date of the Comsat Junior Loan has not been
made.

     (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  (which shall not include
the Class A-8Z  Certificates or the Class B-3SC  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  Delinquent  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
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 last  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  or in  respect  of  Reduction  Interest
Distribution Amounts and Reduction Interest  Shortfalls.  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 (and with  respect to a P&I Advance,  the Trustee or the
Fiscal Agent, as applicable, shall rely on the Servicer's determination that the
Advance would be a  Nonrecoverable  Advance if the Trustee or Fiscal  Agent,  as
applicable,  determines  that it does  not  have  sufficient  time to make  such
determination); 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.

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 Class B-7  Certificates  shall each be issued as one or more Individual
Certificates,   substantially   in  the  form  of  Exhibit  A-21  hereto.   Such
Certificates shall not be issuable as Global  Certificates  unless the Depositor
determines  that  issuance  in such form is  feasible  under  Procedures  of the
Depository  (after  consideration of the date of the  Distribution  Date and the
requirements   of  the   Depository)  and  the  Paying  Agent  concurs  in  such
determination.

     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 Certificateholders (even if
such  Certificateholders  hold their  Certificates  through the  Depository) 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 this 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-26  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,  Certificate Registrar, the Servicer,  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  5.01(i)  and
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.

     (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
5.01(i) and 5.02(c), (d), (e), (f), (g), (h) and (i).

     (c) In addition to the  provisions  of Sections  5.01(i) and 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 complying with all applicable  rules and procedures of the
          Depository  and CEDEL or  Euroclear  applicable  to transfers by their
          respective  participants  (the "Applicable  Procedures"),  transfer or
          cause the  transfer  of such  beneficial  interest  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 Certificate  Registrar at the Corporate Trust Office of
          (1)  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 the Regulation S Global  Certificate
          in an amount equal to the  Denomination of the beneficial  interest in
          the Rule 144A  Global  Certificate  to be  transferred,  (2) a written
          order given in accordance  with the Applicable  Procedures  containing
          information  regarding  the  account  of  the  Agent  Member  and  the
          Euroclear or CEDEL  account,  as the case may be, to be credited with,
          and the account of the Agent Member 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 increase  the  Denomination  of the  Regulation S
          Global  Certificate by the Denomination of the beneficial  interest in
          the Rule 144A Global  Certificate to be so transferred,  and to credit
          or cause to be credited to the account of the Person specified in such
          instructions  (who shall be an Agent Member acting for or on behalf of
          Euroclear or CEDEL, or both, as the case may be) a beneficial interest
          in the Regulation S Global  Certificate having a Denomination equal to
          the  amount  by  which  the  Denomination  of  the  Rule  144A  Global
          Certificate was reduced upon such transfer.

               (B)  Rule  144A  Global   Certificate   to  Regulation  S  Global
          Certificate  After the  Restricted  Period.  If, after 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  holder  may,  in addition to
          complying  with all  Applicable  Procedures,  transfer  or  cause  the
          transfer of such  beneficial  interest  for an  equivalent  beneficial
          interest in such Regulation S Global  Certificate only upon compliance
          with the  provisions of this Section  5.02(c)(ii)(B).  Upon receipt by
          the Certificate Registrar at the Corporate Trust Office of (1) 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 the  Regulation  S Global  Certificate  in an
          amount equal to the  Denomination  of the  beneficial  interest in the
          Rule 144A Global  Certificate to be  transferred,  (2) a written order
          given  in  accordance  with  the  Applicable   Procedures   containing
          information regarding the account of the Agent Member and, in the case
          of a transfer  pursuant to and in  accordance  with  Regulation S, the
          Euroclear or CEDEL  account,  as the case may be, to be credited with,
          and the account of the Agent Member to be debited for, such beneficial
          interest,  and (3) a certificate in the form of Exhibit K 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 aggregate  Denomination of the beneficial  interest
          in  the  Rule  144A  Global  Certificate  to  be so  transferred  and,
          concurrently with such reduction,  to increase the Denomination of the
          Regulation S Global  Certificate by the aggregate  Denomination of the
          beneficial  interest  in the Rule  144A  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 the
          Regulation S Global  Certificate  having a  Denomination  equal to the
          amount by which the  Denomination of the Rule 144A Global  Certificate
          was reduced upon such transfer.

               (C)   Regulation  S  Global   Certificate  to  Rule  144A  Global
          Certificate.  If the Beneficial Owner of an interest in a Regulation S
          Global  Certificate  wishes  at any time to  transfer  its  beneficial
          interest  in such  Regulation  S Global  Certificate  to a Person  who
          wishes to take delivery  thereof in the form of a beneficial  interest
          in the related Rule 144A Global  Certificate,  such  Beneficial  Owner
          may, in addition to complying with all Applicable Procedures, transfer
          or cause the transfer of such  beneficial  interest for an  equivalent
          beneficial  interest  in such Rule 144A Global  Certificate  only upon
          compliance  with the provisions of this Section  5.02(c)(ii)(C).  Upon
          receipt by the Certificate  Registrar at the Corporate Trust Office of
          (1)  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 the Rule 144A Global  Certificate in
          an amount equal to the Denomination of the beneficial  interest in the
          Regulation S Global Certificate to be transferred, (2) a written order
          given  in  accordance  with  the  Applicable   Procedures   containing
          information  regarding  the account of the Agent Member to be credited
          with,  and the account of the Agent Member or, if such account is held
          for Euroclear or CEDEL,  the Euroclear or CEDEL  account,  as the case
          may be, to be debited  for,  such  beneficial  interest,  and (3) with
          respect to a transfer  of a  beneficial  interest  in a  Regulation  S
          Global Certificate for a beneficial  interest in the related Rule 144A
          Global  Certificate (i) during the Restricted Period, a certificate in
          the form of Exhibit L hereto  given by the  holder of such  beneficial
          interest  or  (ii)  after  the   Restricted   Period,   an  Investment
          Representation  Letter  from the  transferee  to the effect  that such
          transferee  is  a  Qualified   Institutional  Buyer,  the  Certificate
          Registrar shall instruct the Depository or the Certificate  Custodian,
          as applicable,  to reduce the  Denomination of the Regulation 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 a
     legend set forth on the face of such Certificate  substantially in the form
     of  Exhibit  G as  attached  hereto  (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
Section  5.01(i)  and 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 Section  5.01(i) and 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-1E,  Class A-2,  Class A-3, Class A-4, Class
A-5, Class A-6,  Class A-7,  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 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 (i) 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 (ii)  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  (i) 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(e)  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 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  (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.

     (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.

     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,  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  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  (x) is an  acquired  servicing  unit  and  (y) is an
affiliate of the Depositor;  provided,  however,  that such replacement Servicer
will not  directly  service  any  Mortgage  Loan in which  an  affiliate  of the
Depositor has an equity interest. 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.

     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,  Servicer,  Special  Servicer and the Trustee its most recent
financial  statements (or in the case of the Servicer or Special  Servicer,  the
financial  statements of AMRESCO,  INC. if no separate financial statements have
been  prepared for the 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  fifteen  (15)  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,  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. 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 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,  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; 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 Certificateholders effecting such termination.

     (c) Each of the Paying Agent, the Certificate Registrar, the Custodian, the
Depositor, the Servicer and the Special Servicer (each, an "Indemnifying Party")
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, an "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 Indemnified
Party  may  sustain  in  connection  with  this  Agreement  (including,  without
limitation,  reasonable  fees  and  disbursements  of  counsel  incurred  by the
Indemnified Party in any action or proceeding between the Indemnifying Party and
the Indemnified  Party or between the  Indemnified  Party and any third party or
otherwise)  related  to  each  such  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 each 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  Indemnified  Party in any action or
proceeding  between the Indemnifying  Party and the Indemnified Party or between
the  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 Indemnified Party and
(ii) those as to which such  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 an 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  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 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 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 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 may 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,  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).

                                   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) Any holder of a Class LR  Certificate  representing  greater than a 50%
Percentage  Interest in such Class 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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30-day period.  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 LR 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 none of the Class A-8Z, Class B-3SC or 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 9.0(g),
if the  Class LR or most  subordinate  Class of  Certificates  (which  shall not
include the Class A-8Z Certificate or the Class B-3SC Certificate) 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.

     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,  or (v) 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  Interest 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, 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
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.

     This certifies that _______________________________ 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-1D,
Class A-CS1, Class PS-1, Class A-1E, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7, 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 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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  ______________________________ 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-1D,
Class A-CS1, Class PS-1, Class A-1E, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7, 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-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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                  (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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 ____________________________ 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-1D,
Class A-CS1, Class PS-1, Class A-1E, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7, 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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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 _______________________________ 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-1D  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-1E, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7, 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-1D  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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-1D 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-1D 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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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 __________________________ 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-1E 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-1D, Class A-CS1, Class PS-1, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7, 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-1E  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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-1E 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-1E 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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                  (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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-2-

     This certifies that  ________________________  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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-3, Class A-4, Class
A-5, Class A-6,  Class A-7,  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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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

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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  ______________________________ 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-1D,  Class A-1E,  Class A-CS1,  Class PS-1,  Class A-2, Class A-4, Class
A-5, Class A-6,  Class A-7,  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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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-4-

     This certifies that ____________________________ 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-5, Class A-6,  Class A-7,  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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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

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

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.

Percentage  Interest in such Class may effect an early  termination of the Trust
Fund,  upon not less  than 30 days'  prior  Notice of  Termination  given 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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                                    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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.

than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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-6-

     This certifies that ____________________________ 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-6  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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-7,  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  Class  A-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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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-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 A-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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                                    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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  _________________________ 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-6 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  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  Class  A-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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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-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 A-7 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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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

     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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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 __________________________ 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-8Z 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4,  Class A-5,  Class A-6,  Class A-7,  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  Class  A-8Z
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").  The  beneficial  ownership  interest  represented by the
Class  A-8Z  Certificates  corresponds  only to the  portion  of the Trust  Fund
consisting of the Comsat Junior Loan.

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and Servicing  Agreement dated as of October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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-8Z 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-8Z 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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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 Comsat Junior Loan, as more
specifically set forth herein and in the Pooling and Servicing Agreement.

     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. 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  herein or 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
                         Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

               (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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-CS1-

     This certifies that  _______________________  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-CS1  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-1D,  Class PS-1, Class A-1E, Class A-2, Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, 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-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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 is assumed to consist of 30 days. The Interest  Accrual Period
with respect to the  Distribution  Date occurring in November 1997 shall consist
of the actual number of 16 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates with an aggregate initial Notional Balance in excess of $5,000,000,
and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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

                                    of the last day of the month  preceding such
                                    Distribution Date;

                           (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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                  (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.:  PS-1-

     This certifies that __________________________ 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-1D, Class A-CS1, Class A-1E, Class A-2, Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, 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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 is assumed to consist of 30 days. The Interest  Accrual Period
with respect to the  Distribution  Date occurring in November 1997 shall consist
of the actual number of 16 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates with an aggregate initial Notional Balance in excess of $5,000,000,
and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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

                                    any P&I Advances  previously made on account
                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

                                    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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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. 

     IN WITNESS  WHEREOF,  the Trustee has caused this Class PS-1 Certificate to
be duly executed.

     This certifies  that  _____________________  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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  _______________________  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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  Class B-1, 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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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:

                           to  the  last  day  of  the  month   preceding   such
                           Distribution Date, together with one month's interest
                           thereon at the Mortgage Rate.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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 ___________________________. 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-1D,  Class A-1E,  Class A-CS1,  Class PS-1,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  ___________________________ 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-3SC 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  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  B-3SC
Certificates,  the "Certificates";  the Holders of Certificates issued under the
Pooling  and  Servicing  Agreement  are  collectively   referred  to  herein  as
"Certificateholders").  The  beneficial  ownership  interest  represented by the
Class  B-3SC  Certificates  corresponds  only to the  portion  of the Trust Fund
consisting of the SC Junior Portion of the Saul Centers Retail Pool Loan.

     This  Certificate is issued pursuant to, and in accordance  with, the terms
of a Pooling and Servicing  Agreement dated as of October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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  then  distributable,  if any,
allocable to the Class B-3SC  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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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 SC Junior Portion of the
Saul Centers Retail Pool Loan, as more  specifically set forth herein and in the
Pooling and Servicing Agreement.

     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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  ___________________________ 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  Class B-1, Class B-2, Class
B-3, Class B-3SC,  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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;

                           of all the holders of all  Certificates  representing

                           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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  specifying  the
Anticipated  Termination Date, by purchasing on such date all, but not less than

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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  _______________________  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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class

B-3, Class B-3SC,  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  _________________________ 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-6 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, Class
A-4, Class A-5,  Class A-6,  Class A-7, Class A-8Z,  Class B-1, Class B-2, Class
B-3, Class B-3SC,  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (B)      the fair market value of all other  property

                                    Mortgaged Property has been acquired) at the
                                    Mortgage  Rate (plus the Excess Rate, to the
                                    extent  applicable)  to the  last day of the

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the
                                    Advance   Rate,    and   unpaid    Servicing
                                    Compensation,        Special       Servicing

                                    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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  ______________________________ 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2,  Class A-3, Class A-4,
Class A-5, Class A-6,  Class A-7,  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-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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates with an aggregate initial Notional Balance in excess of $5,000,000,
and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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-7H-

     This certifies that ____________________________ 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2,  Class A-3, Class A-4,
Class A-5, Class A-6,  Class A-7,  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 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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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
November  17, 1997  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 November 10, 1997.  Each Interest  Accrual Period other than the
Interest  Accrual  Period with  respect to the  Distribution  Date  occurring on
November 17, 1997 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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates with an aggregate initial Notional Balance in excess of $5,000,000,
and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.

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

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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 the right to receive Default Interest,  subject
to the obligation to reimburse the Servicer, the Trustee or the Fiscal Agent, as
applicable, for interest on Advances.

     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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (B)      the fair market value of all other  property
                                    included  in the  Trust  Fund as of the last

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

     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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.

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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 the right to receive Excess  Interest,  which
portions 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 fourteenth day of each month, or
if such day is not a Business Day, the Business Day  immediately  following such
day,  commencing  in  November,  1997 (each such date, a  "Distribution  Date");
provided,  however,  that in any month the Distribution  Date will be no earlier
than the third  Business  Day  following  the  eleventh  day of such  month and;
provided  further,  that if the eleventh day of any month is not a Business Day,
the  Distribution  Date shall be the fourth  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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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

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

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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.

THEIR  RESPECTIVE  AFFILIATES.  NEITHER  THE  CERTIFICATES  NOR  THE  UNDERLYING
MORTGAGE  LOANS  ARE  INSURED  OR  GUARANTEED  BY  ANY  GOVERNMENTAL  AGENCY  OR

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

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

HOLDER  REASONABLY  BELIEVES  IS A  QUALIFIED  INSTITUTIONAL  BUYER,  WITHIN THE
MEANING  OF  RULE  144A  ("QIB")  PURCHASING  FOR ITS OWN  ACCOUNT  OR A  PERSON
PURCHASING FOR THE ACCOUNT OF A QIB, WHOM THE HOLDER HAS INFORMED, IN EACH CASE,
THAT THE REOFFER, RESALE, PLEDGE, OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON
RULE 144A OR (2) IN CERTIFICATED FORM TO AN "INSTITUTIONAL  ACCREDITED INVESTOR"
AS SUCH TERM IS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF REGULATION D UNDER
THE 1933 ACT AND (B) IN ACCORDANCE WITH ANY OTHER APPLICABLE  SECURITIES LAWS OF
ANY STATE OF THE UNITED STATES.

THIS CERTIFICATE SHOULD NOT BE PURCHASED BY A TRANSFEREE THAT IS (A) AN EMPLOYEE

TRANSFEREE IS SUCH AN ENTITY  SPECIFIED IN (A) OR (B) 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

     This certifies that  ______________________________ 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-1D,  Class A-CS1,  Class PS-1,  Class A-1E,  Class A-2, Class A-3, 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  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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 Internal Revenue Code of 1986, as amended.

     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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreements and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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;

                           (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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  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

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

CUSIP:  045424 GD4                                     Percentage Interest: 100%

No.: LR--

     This certifies that _______________________________ 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-1D, Class A-CS1,  Class PS-1, Class A-1E,
Class A-2,  Class A-3,  Class A-4,  Class A-5, Class A-6, Class A-7, 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 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 October 24, 1997 (the "Pooling
and Servicing  Agreement"),  by and among Asset Securitization  Corporation,  as
Depositor,  AMRESCO Services,  L.P., as Servicer,  AMRESCO Management,  Inc., 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 Internal Revenue Code of 1986, as amended.

     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; provided,  however,  that
with respect to the  Distribution  Date  occurring in November  1997, the Record
Date will be the Closing Date,  except as specified in the Pooling and Servicing
Agreement. 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   holds
Certificates  with  an  aggregate  initial  Certificate  Balance  in  excess  of
$5,000,000,  and 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  Agreement,  Bloomfield
Purchase Agreement and First Boston 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. 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  herein or 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
                           Interest 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.

     Any  Holder  of  Class  LR  Certificates  representing  greater  than a 50%
Percentage  Interest in such Class 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
Swiss Bank Tower Loan,  Kmart Loans and/or  Circuit City Loans)  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:

                                    Distribution Date;

                                    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

                                    of interest);

                           (D)      the   aggregate   amount   of   unreimbursed
                                    Advances,   with  interest  thereon  at  the

          (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.

     The Servicer or the Depositor may also effect such  termination as provided
above if it first  notifies  each Holder of a Class LR  Certificate  through the
Trustee of its intention to do so in writing at least 30 days prior to the Early
Termination  Notice  Date and no Class LR Holder  terminates  the Trust  Fund as
described  above within such 30 day period.  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  surviving  descendant(s)  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.

              Re:  Transfer of Asset Securitization Corporation, Commercial
                   Mortgage Pass-Through Certificates, Series 1997-D5

Ladies and Gentlemen:

     This  letter is  delivered  pursuant  to Section  5.02 of the  Pooling  and
Servicing  Agreement  dated as of October 24, 1997 (the  "Pooling and  Servicing
Agreement"),  by and  among  Asset  Securitization  Corporation,  as  depositor,
AMRESCO  Services,  L.P.,  as servicer,  AMRESCO  Management,  Inc.,  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 Asset
Securitization  Corporation,   Commercial  Mortgage  Pass-Through  Certificates,
Series  1997-D5  (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
October  24,  1997,   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 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) for taxable years beginning
after  December 31, 1996 (or for taxable  years ending after August 20, 1996, if
the trustee has made an applicable election) 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 (B) for all other taxable years,  such
trust is subject to United States federal income tax regardless of the source of
its income  (or,  to the extent  provided in  applicable  Treasury  Regulations,

[B-7][B-7H][V-1][V-2][R][LR],  CUSIP No.  045424-________ (the  "Certificates"),
issued  pursuant  to the Pooling  and  Servicing  Agreement  (the  "Pooling  and
Servicing  Agreement")  dated  as of  October  24,  1997,  by  and  among  Asset
Securitization  Corporation,  as depositor (the "Depositor"),  AMRESCO Services,

the  meaning set forth in the Pooling and  Servicing  Agreement.  The  Purchaser
hereby certifies, represents and warrants to, and covenants with, the Depositor,
the Certificate Registrar and the Trustee that:

     1. The  Purchaser is not (a) an employee  benefit plan or other  retirement
arrangement,  including an individual  retirement account or a Keogh plan, which
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
Letter on __________, __________.

                          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"),  AMRESCO  Management,  Inc.,  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 October 24, 1997, among Asset  Securitization  Corporation,  as Depositor,
the  Servicer,  the Special  Servicer,  the  Trustee and ABN AMRO Bank N.V.,  as
Fiscal Agent, relating to Asset Securitization Corporation, Commmercial Mortgage
Pass-Through  Certificates,  Series  1997-D5  (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 AMRESCO Management, Inc. 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.

                                   the  Seller,  or  result in the  creation  or

                                   Seller   to   carry   out  the   transactions
                                   contemplated  by this  Agreement.  The Seller

                                   authorization   or  order  of  any  court  or
                                   governmental  agency or body required for the

                         (v)       There  is  no  action,   suit  or  proceeding
                                   pending against the Seller in any court or by

                                   instrumentality  which would  materially  and
                                   adversely affect the ability of the Seller to

                                   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.

                                   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

                                   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

                                   amounts  generally  required by institutional
                                   lenders for similar properties;  all premiums
                                   on such  insurance  policies  required  to be
                                   paid as of the date  hereof  have been  paid;
                                   such insurance  policies require prior notice
                                   to   the    insured   of    termination    or
                                   cancellation,  and no such  notice  has  been
                                   received;   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

                                   Materials;  the  related  Borrower  agrees to
                                   indemnify,  defend and hold the mortgagee and
                                   its successors and assigns  harmless from and

                                   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

                                   Supplement,  dated  October  24,  1997 to the

                                   "Prospectus"), does not indicate any material
                                   non-compliance   or  material   existence  of

                                   Seller's  knowledge,  each related  Mortgaged
                                   Property,   except   as   disclosed   in  the
                                   Prospectus   Supplement,   is   in   material

                                   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

                                   Agreement  or  obtaining  the  prior  written
                                   consent  of  the   Mortgagee,   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 as
                                   evidenced  by  an  MAI  appraisal   conducted
                                   within 12 months  of the  origination  of the
                                   Mortgage  Loan,  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

                                   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

                                    estate  and the fee  interest  of the ground
                                    lessor is not subject and subordinate to the
                                    related Mortgage,  the Seller represents and

                                   (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

                                        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;

                                        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)  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  Mortgaged
                                        Property  known as the  Roseburg  Valley
                                        Mall  Property,   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   execution   and
                                        delivery,  the  ground  lease is in full

                                        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;

                                        to the mortgagee;

                                        default  under the ground lease which is
                                        curable  after the  receipt of notice of
                                        any   default   before  the  lessor  may

                                        relates  to  the  ground  lease)  may be
                                        exercised   by  or  on   behalf  of  the

                                   (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,

                                        reason,  or in any  manner,  which would
                                        adversely  affect the security  provided
                                        by the related Mortgage;

                                   (J)  Any   related   insurance   proceeds  or

                                        to hold and  disburse  such  proceeds as
                                        repair or restoration progresses, or, if
                                        permitted by the related  ground  lease,

                                        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; and

                                   (K)  Under the terms of the ground  lease and
                                        the   related   Mortgage,   any  related

                                        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   as   provided   by
                                        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

                                        paid in full, neither the lessee nor the
