Ladies and Gentlemen:

     GMAC Commercial  Mortgage  Securities,  Inc., a Delaware  corporation  (the

"Underwriters"),  the respective classes of Mortgage Pass-Through  Certificates,
Series  1999-C1,  that are  identified  on Schedule I, in each case,  having the
initial  aggregate  stated  principal  amount (a "Class  Principal  Balance") or
initial  aggregate  notional  principal  amount (a "Class Notional  Amount") and
initial  pass-through  rate set  forth on  Schedule  I (such  Certificates,  the
"Underwritten Certificates").  The Class X, Class A-1, Class A-2, Class B, Class
C, Class D and Class E Certificates (collectively, the "Certificates"), together
with the Class F,  Class G,  Class H,  Class J and Class K  Certificates  issued
therewith,  will  evidence the entire  interest in the Trust Fund (as defined in
the Pooling and Servicing Agreement referred to below) consisting primarily of a
pool (the "Pool") of multifamily  and  commercial  mortgage loans (the "Mortgage
Loans") as described in the Prospectus Supplement (as hereinafter defined) to be
sold by the Company.

     The  Certificates  will be issued under a pooling and  servicing  agreement
(the "Pooling and Servicing Agreement") to be dated as of February 1, 1999 among
the Company, as depositor,  GMAC Commercial Mortgage Corporation ("GMACCM"),  as
master servicer (in such capacity,  the "Master  Servicer") and special servicer
(in such capacity, the "Special 


<PAGE>


Servicer"),  and Norwest Bank Minnesota,  National Association,  as trustee (the
"Trustee").  The  Certificates  are  described in the Basic  Prospectus  and the
Prospectus  Supplement  (each as  hereinafter  defined)  which the  Company  has
furnished to the Underwriters.

     Certain  of the  Mortgage  Loans  (the  "GMACCM  Mortgage  Loans")  will be
acquired  by the  Company  from  GMACCM  pursuant  to a mortgage  loan  purchase
agreement,  dated as of February 2, 1999 (the  "GMACCM  Mortgage  Loan  Purchase
Agreement"),  between the Company and GMACCM. Certain of the Mortgage Loans (the
"ML Trust Mortgage Loans") will be acquired by the Company from LaSalle National
Bank as Trustee for  Restructured  Asset  Certificates  With  Enhanced  Returns,
Series  1998-ML  Trust  ("ML  Trust")  pursuant  to  a  mortgage  loan  purchase
agreement,  dated as of February 2, 1999 (the "ML Trust  Mortgage  Loan Purchase
Agreement"),  between the Company and ML Trust.  Certain of the  Mortgage  Loans
(the "GACC Mortgage Loans") will be acquired by the Company from German American
Capital  Corporation  ("GACC")  pursuant to a mortgage loan purchase  agreement,
dated as of  February 2, 1999 (the "GACC  Mortgage  Loan  Purchase  Agreement"),
between the Company and GACC (the GACC Mortgage Loans,  together with the GMACCM
Mortgage Loans and the ML Trust Mortgage Loans, the "Mortgage  Loans").  GMACCM,
ML Trust and GACC together  constitute the "Mortgage Loan Sellers." The "Cut-off
Date" with respect to each Mortgage Loan shall be the due date for such Mortgage
Loan in February 1999.

     1. Representations, Warranties and Covenants.

     1.1  The  Company   represents   and  warrants  to,  and  agrees  with  the
Underwriters that:

          (a) The Company has filed with the Securities and Exchange  Commission
     (the "Commission") a registration statement (No. 333-64963) on Form S-3 for
     the registration  under the Securities Act of 1933, as amended (the "Act"),
     of Mortgage Pass-Through  Certificates (issuable in series),  including the
     Certificates, which registration statement has become effective, and a copy
     of which,  as amended to the date hereof,  has heretofore been delivered to
     the Underwriters. The Company proposes to file with the Commission pursuant
     to Rule 424(b) under the rules and regulations of the Commission  under the
     Act (the "1933 Act  Regulations") a supplement  dated February 2, 1999 (the
     "Prospectus  Supplement"),  to the  prospectus  dated November 5, 1998 (the
     "Basic  Prospectus"),  relating  to the  Certificates  and  the  method  of
     distribution thereof. Such registration statement (No. 333-64963) including
     exhibits thereto and any information  incorporated therein by reference, as
     amended  at the  date  hereof,  is  hereinafter  called  the  "Registration
     Statement;"  the Basic  Prospectus  and the  Prospectus  Supplement and any
     information   incorporated   therein  by  reference   (including,   without
     limitation,  and only for purposes of clarification,  any information filed
     with the  Commission  pursuant to a Current  Report on Form 8-K),  together
     with any amendment thereof or supplement  thereto authorized by the Company
     on or prior to the Closing Date for use in connection  with the offering of
     the Certificates,  are hereinafter called the "Prospectus" and any diskette


                                       2
<PAGE>



     attached  to the  Prospectus  is  hereinafter  called the  "Diskette."  Any
     preliminary  form of the Prospectus  Supplement  which has heretofore  been
     filed  pursuant  to  Rule  424,  or  prior  to the  effective  date  of the
     Registration  Statement  pursuant to Rule 402(a),  or 424(a) is hereinafter
     called a "Preliminary  Prospectus Supplement;" and any diskette attached to
     the  Preliminary  Prospectus  Supplement is hereinafter  referred to as the
     "Preliminary  Diskette."  As used  herein,  "Pool  Information"  means  the
     compilation of information and data regarding the Mortgage Loans covered by
     the Agreed Upon  Procedures  Letter dated  February 2, 1999 and rendered by
     Deloitte & Touche,  L.L.P.  (a "hard  copy" of which Pool  Information  was
     initialed on behalf of each Mortgage Loan Seller and the Company).

          (b)  The  Registration   Statement  has  become  effective,   and  the
     Registration Statement as of its effective date (the "Effective Date"), and
     the Prospectus,  as of the date of the Prospectus  Supplement,  complied in
     all material  respects with the applicable  requirements of the Act and the
     1933 Act Regulations;  and the Registration  Statement, as of the Effective
     Date,  did not contain any untrue  statement of a material fact and did not
     omit to state any material fact required to be stated  therein or necessary
     to make the  statements  therein not  misleading and the Prospectus and any
     Diskette, as of the date of the Prospectus  Supplement,  did not, and as of
     the Closing Date will not,  contain an untrue  statement of a material fact
     and did not and will not omit to state a material  fact  necessary in order
     to make the statements  therein,  in the light of the  circumstances  under
     which they were made, not misleading;  provided,  however, that neither the
     Company  nor  GMACCM  makes any  representations  or  warranties  as to the
     information contained in or omitted from the Registration  Statement or the
     Prospectus or any amendment  thereof or supplement  thereto relating to the
     information  identified by  underlining or other  highlighting  as shown in
     Exhibit C (the "Excluded Information"); and provided, further, that neither
     the Company nor GMACCM makes any representations or warranties as to either
     (i) any information in any Computational Materials or ABS Term Sheets (each
     as hereinafter  defined) required to be provided by the Underwriters to the
     Company pursuant to Section 4.2, or (ii) as to any information contained in
     or omitted from the portions of the Prospectus identified by underlining or
     other  highlighting as shown in Exhibit D (the "Underwriter  Information");
     and provided, further, that neither the Company nor, except as contemplated
     by Section 1.2(a),  GMACCM,  makes any  representations or warranties as to
     any  information  regarding the Mortgage Loans or the Mortgage Loan Sellers
     contained  in or omitted  from the  portions of the  Prospectus  Supplement
     under  the  headings  "Summary   Information--The   Mortgage  Pool,"  "Risk
     Factors--Risks  Related  to the  Mortgage  Loans" and  "Description  of the
     Mortgage  Asset  Pool"  or  contained  in or  omitted  from  Annex A to the
     Prospectus  Supplement  or contained  in or omitted from the Diskette  (the
     "Mortgage  Loan Seller  Information"),  other than that the  Mortgage  Loan
     Seller  Information  (exclusive of the  information  set forth on pages A-8
     through A-11, inclusive, of Annex A to the Prospectus Supplement (the "Loan
     Detail") and the information on the Diskette) that represents a restatement
     of the information on the Loan Detail,  accurately reflects the information
     contained  in the Loan  Detail;  and  provided,  further,  that neither the
     Company nor GMACCM makes any  representations or warranties with respect to
     the Diskette to the extent that the  information  set forth in the Diskette
     is different than the information set forth in the Loan Detail. Neither the
     Company nor, except as  contemplated  by Section  1.2(a),  GMACCM makes any
     representations or warranties,  however, as to the accuracy or completeness
     of any  information  in the Loan  Detail.  The Company  acknowledges  that,
     except for any Computational Materials and ABS Term Sheets, the Underwriter
     Information  constitutes the only information furnished in writing by or on
     behalf of any Underwriter for use in 


                                       3
<PAGE>



     connection  with  the  preparation  of  the  Registration  Statement,   any
     preliminary prospectus or the Prospectus, and the Underwriters confirm that
     the Underwriter Information is correct.

          (c) The Company has been duly  incorporated and is validly existing as
     a corporation  in good standing under the laws of the State of Delaware and
     has the requisite  corporate power to own its properties and to conduct its
     business as presently conducted by it.

          (d) This Agreement has been duly authorized, executed and delivered by
     the Company and, assuming due authorization,  execution and delivery by the
     Underwriters,  constitutes  a valid,  legal and binding  obligation  of the
     Company,  enforceable  against  the  Company in  accordance  with the terms
     hereof, subject to (i) applicable bankruptcy,  insolvency,  reorganization,
     moratorium  and other laws affecting the  enforcement of creditors'  rights
     generally,  (ii) generally principles of equity, regardless of whether such
     enforcement  is  considered  in a proceeding in equity or at law, and (iii)
     public policy considerations  underlying the securities laws, to the extent
     that such public  policy  considerations  limit the  enforceability  of the
     provisions of this  Agreement that purport to provide  indemnification  for
     securities laws liabilities.

          (e) As of the Closing Date (as defined herein),  the Certificates will
     conform in all material  respects to the description  thereof  contained in
     the Prospectus and the representations and warranties of the Company in the

     in a proceeding in equity or at law, and (iii) public policy considerations
     underlying  the  securities  laws to the  extent  that such  public  policy
     considerations limit the enforceability of the provisions of this Agreement
     that purport to provide indemnification for securities laws liabilities.

     1.3 Each Underwriter represents and warrants to and agrees with the Company
and GMACCM that:

          (a) With respect to each class of Underwritten  Certificates,  if any,
     to be  issued  in  authorized  denominations  of  $25,000  or less  initial
     principal balance or

     Section 4.2, if any, such  Computational  Materials and ABS Term Sheets are
     accurate in all material  respects  (taking  into  account the  assumptions
     explicitly  set forth in the  Computational  Materials  or ABS Term Sheets,
     except to the extent of any errors therein that are caused by errors in the
     Pool  Information) and include all assumptions  material to the preparation
     thereof.  The Computational  Materials and ABS Term Sheets provided by such
     Underwriter to the Company  constitute a complete set of all  Computational
     Materials and ABS Term Sheets  delivered by such Underwriter to prospective
     investors that are required to be filed with the Commission.

     2. Purchase and Sale.  Subject to the terms and  conditions and in reliance
upon the  representations and warranties herein set forth, the Company agrees to
sell to each of the Underwriters, and each of the Underwriters agrees, severally
and not jointly,  to purchase from the Company,  the actual or notional,  as the
case may be, principal  amounts or percentage  interests set forth in Schedule I
hereto in the respective  classes of  Underwritten  Certificates  at a price for
each such  class  set forth in  Schedule  I hereto.  There  will be added to the
purchase  prices of the  Underwritten  Certificates  an amount equal to interest
accrued thereon from the Cut-off Date to but not including the Closing Date.

     3.  Delivery  and  Payment.  Delivery of and  payment for the  Underwritten
Certificates  shall be made at the office of Orrick,  Herrington & Sutcliffe LLP
at 10:00 a.m., New York City time, on February 9, 1999 or such later date as the
Underwriters shall designate,  which date and time may be postponed by agreement
between the  Underwriters  and the Company  (such date and time of delivery  and
payment for the  Underwritten  Certificates  being  herein  called the  "Closing
Date").  Delivery of the Underwritten  Certificates  (also referred to herein as
the "DTC Registered  Certificates")  shall be made to the respective accounts of
the  Underwriters  through DTC, in each case against payment by the Underwriters
to or upon the order of GMACCM by wire transfer in immediately  available  funds
of the amount that has been agreed to by GMACCM and the Company  (net of certain
expenses, which will be paid by the Underwriters on behalf of the Company). As a
further  condition  to the  delivery of the DTC  Registered  Certificates,  each
Underwriter  shall have  furnished  by  telephonic  notice to GMACCM the federal
reference  number  for the  related  wire  transfer  to GMACCM  and  shall  have
furnished  to the  Company  each  such  federal  reference  number  as  soon  as
practicable after such federal reference number becomes available.

     4. Offering by Underwriters.

     4.1  It  is  understood  that  the   Underwriters   propose  to  offer  the

          SUPPLEMENT AND BY ANY OTHER  INFORMATION  SUBSEQUENTLY  FILED WITH THE
          SECURITIES AND EXCHANGE COMMISSION."

          (ii) In the case of  Collateral  Term  Sheets,  such legend shall also
     include the following statement:

          "THE   INFORMATION   CONTAINED   HEREIN  WILL  BE  SUPERSEDED  BY  THE
          DESCRIPTION   OF  THE  MORTGAGE  POOL   CONTAINED  IN  THE  PROSPECTUS
          SUPPLEMENT  RELATING TO THE CERTIFICATES AND [, EXCEPT WITH RESPECT TO
          THE  INITIAL  COLLATERAL  TERM SHEET  PREPARED  BY THE  UNDERWRITERS,]
          SUPERSEDES ALL  INFORMATION  CONTAINED IN ANY  COLLATERAL  TERM SHEETS
          RELATING  TO  THE  MORTGAGE  POOL  PREVIOUSLY  PROVIDED  BY  [NAME  OF

     The Company shall have the right to require additional  specific legends or
     notations to appear on any Computational  Materials or ABS Term Sheets, the
     right to require changes  regarding the use of terminology and the right to
     determine the types of information  appearing therein.  Notwithstanding the
     foregoing,  subsections  (c)(i)  and  (c)(ii)  will  be  satisfied  if  all
     Computational  Materials  and ABS Term Sheets  referred  to therein  bear a
     legend in a form previously approved in writing by the Company.

          (d) Such  Underwriter  shall  provide the Company with  representative
     forms of all  Computational  Materials  and ABS Term Sheets  prior to their
     first use, to the extent such forms have not  previously  been  approved by
     the Company for use by the Underwriters.  Such Underwriter shall provide to
     the Company,  for filing on Form 8-K as provided in Section 5.9, copies (in
     such format as required by the Company) of all Computational  Materials and
     ABS Term Sheets that are required to be filed with the Commission  pursuant
     to the  No-Action  Letters.  Such  Underwriter  may  provide  copies of the
     foregoing in a consolidated  or aggregated  form including all  information
     required  to be filed.  All  Computational  Materials  and ABS Term  Sheets
     described in this  subsection (d) must be provided to the Company not later
     than 10:00 a.m.  New York time one business  day before  filing  thereof is
     required pursuant to the terms of this Agreement.  Such Underwriter  agrees
     that it will not  provide to any  investor or  prospective  investor in the
     Certificates any Computational Materials or ABS Term Sheets on or after the
     day on which Computational Materials and ABS Term Sheets are required to be
     provided to the Company  pursuant to this Section 4.2(d) (other than copies
     of Computational  Materials or 



                                       7
<PAGE>


     ABS Term Sheets previously submitted to the Company in accordance with this
     Section   4.2(d)  for  filing   pursuant  to  Section  5.9),   unless  such
     Computational  Materials or ABS Term Sheets are preceded or  accompanied by
     the delivery of a Prospectus to such investor or prospective investor.

          (e) All information  included in the  Computational  Materials and ABS
     Term Sheets shall be generated based on substantially  the same methodology
     and assumptions that are used to generate the information in the Prospectus
     Supplement as set forth therein; provided,  however, that the Computational
     Materials and ABS Term Sheets may include  information based on alternative
     methodologies  or assumptions if specified  therein.  If any  Computational
     Materials  or ABS  Term  Sheets  delivered  by such  Underwriter  that  are
     required  to be filed were based on  assumptions  with  respect to the Pool
     that differ from the final Pool  Information in any material  respect or on
     Certificate  structuring  terms that were revised in any  material  respect
     prior to the printing of the  Prospectus,  such  Underwriter  shall prepare
     revised  Computational  Materials or ABS Term  Sheets,  as the case may be,
     based on the final  Pool  Information  and final  structuring  assumptions,
     circulate such revised  Computational  Materials and ABS Term Sheets to all
     recipients of the  preliminary  versions  thereof that indicated  orally to
     such   Underwriter   they  would   purchase  all  or  any  portion  of  the
     Certificates, and include such revised Computational Materials and ABS Term
     Sheets  (marked,  "as revised") in the  materials  delivered to the Company
     pursuant to subsection (d) above.

          (f) The  Company  shall  not be  obligated  to file any  Computational
     Materials  or ABS Term  Sheets  that have been  determined  to contain  any
     material error or omission, provided that, at the request of the applicable
     Underwriter,  the Company  will file  Computational  Materials  or ABS Term
     Sheets  that  contain  a  material  error or  omission  if  clearly  marked
     "superseded by materials  dated  __________"  and  accompanied by corrected
     Computational  Materials  or ABS  Term  Sheets  that are  marked  "material
     previously  dated  _________,  as  corrected." In the event that within the
     period during which the Prospectus relating to the Certificates is required
     to be  delivered  under the Act,  any  Computational  Materials or ABS Term
     Sheets  delivered  by an  Underwriter  are  determined,  in the  reasonable
     judgment of the Company or such Underwriter, to contain a material error or
     omission,  such  Underwriter  shall  prepare a  corrected  version  of such
     Computational  Materials or ABS Term Sheets, shall circulate such corrected
     Computational  Materials and ABS Term Sheets to all recipients of the prior
     versions  thereof that either  indicated  orally to such  Underwriter  they
     would  purchase  all  or  any  portion  of the  Certificates,  or  actually
     purchased  all or any portion  thereof,  and shall  deliver  copies of such
     corrected   Computational  Materials  and  ABS  Term  Sheets  (marked,  "as
     corrected")  to the Company for filing with the  Commission in a subsequent
     Form 8-K  submission  (subject to the Company's  obtaining an  accountant's
     comfort letter in respect of such corrected Computational Materials and ABS
     Term Sheets, which shall be at the expense of such Underwriter).

          (g) If an Underwriter does not provide any Computational  Materials or
     ABS Term  Sheets to the  Company  pursuant to  subsection  (d) above,  such
     Underwriter  shall be deemed to have  represented,  as of the Closing Date,
     that it did not provide any  prospective  investors with any information in
     written  or  electronic  form  in  connection  



                                       8

     with the offering of the Certificates that is required to be filed with the
     Commission in accordance with the No-Action  Letters,  and such Underwriter
     shall  provide  the  Company  with a  certification  to that  effect on the
     Closing Date.

          (h) In the event of any delay in the delivery by such  Underwriter  to
     the Company of all Computational  Materials and ABS Term Sheets required to
     be delivered in accordance with subsection (d) above, or in the delivery of
     the accountant's comfort letter in respect thereof pursuant to Section 5.9,
     the Company shall have the right to delay the release of the  Prospectus to
     investors  or to the  Underwriters,  to delay the Closing  Date and to take
     other appropriate  actions, in each case as necessary in order to allow the
     Company to comply with its  agreement  set forth in Section 5.9 to file the
     Computational Materials and ABS Term Sheets by the time specified therein.

          (i) The  Underwriter  represents  that it has in place,  and covenants
     that it shall maintain internal controls and procedures which it reasonably
     believes to be sufficient  to ensure full  compliance  with all  applicable
     legal  requirements of the No-Action Letters with respect to the generation
     and use of  Computational  Materials and ABS Term Sheets in connection with
     the offering of the Certificates.

          (j) Notwithstanding  anything herein to the contrary,  for purposes of
     this Agreement,  neither the Preliminary Diskette nor the Diskette shall be
     deemed to be Computational Materials or ABS Term Sheets.

     Each  Underwriter  represents  and warrants  that,  if and to the extent it
provided any prospective investors with any Computational Materials or ABS Terms
Sheets  prior  to the  date  hereof  in  connection  with  the  offering  of the
Certificates,  all of the  conditions set forth in clauses (a) through (h) above
have been or, to the extent the relevant  condition  requires action to be taken
after the date hereof, will be, satisfied with respect thereto.

     4.3 Each  Underwriter  further  agrees  that,  on or prior to the sixth day
after the  Closing  Date,  it shall  provide  the  Company  with a  certificate,
substantially in the form of Exhibit E attached hereto, setting forth (i) in the
case of each  class of  Underwritten  Certificates,  (a) if less than 10% of the
aggregate  actual or  notional,  as the case may be,  principal  balance of such
class of Underwritten  Certificates has been sold to the public as of such date,
the value calculated pursuant to clause (b)(iii) of Exhibit E hereto, or, (b) if
10% or more of such  class of  Underwritten  Certificates  has been  sold to the
public  as of such  date but no  single  price  is paid for at least  10% of the
aggregate  actual or  notional,  as the case may be,  principal  balance of such
class of Underwritten Certificates, then the weighted average price at which the
Underwritten  Certificates  of such class were sold expressed as a percentage of
the aggregate actual or notional,  as the case may be, principal balance of such
class of Underwritten  Certificates sold, or (c) the first single price at which
at least 10% of the aggregate actual or notional,  as the case may be, principal
balance of such class of Underwritten  Certificates was sold to the public, (ii)
the  prepayment   assumption   used  in  pricing  each  class  of   Underwritten
Certificates,  and (iii)  such  other  information  as to matters of fact as the
Company  may  reasonably  request  to  enable it to  comply  with its  reporting
requirements  with  respect to each class of  Underwritten  Certificates  to the
extent such  information  can in the good faith judgment of such  Underwriter be
determined by it.

     5. Agreements. The Company agrees with the several Underwriters that:

     5.1 Before  amending or  supplementing  the  Registration  Statement or the
Prospectus  with  respect to the  Underwritten  Certificates,  the Company  will
furnish  the  Underwriters  with a copy  of  each  such  proposed  amendment  or
supplement.

     5.2 The Company will cause the  Prospectus  Supplement to be transmitted to
the  Commission  for  filing  pursuant  to Rule  424(b)  under  the Act by means
reasonably  calculated to result in filing with the Commission  pursuant to said
rule.

     5.3 If,  during the period  after the first date of the public  offering of
the Underwritten Certificates in which a prospectus relating to the Underwritten
Certificates  is required to be  delivered  under the Act, any event occurs as a
result of which it is necessary to amend or supplement the  Prospectus,  as then
amended or supplemented,  in order to make the statements  therein, in the light
of the  circumstances  when the  Prospectus  is delivered  to a  purchaser,  not
misleading, or if it shall be necessary to amend or supplement the Prospectus to
comply  with the Act or the 1933 Act  Regulations,  the  Company  promptly  will
prepare and furnish, at its own expense, to the Underwriters,  either amendments
or  supplements to the Prospectus so that the statements in the Prospectus as so
amended or  supplemented  will not, in the light of the  circumstances  when the
Prospectus is delivered to a purchaser,  be misleading or so that the Prospectus
will comply with law.

     5.4 The Company will furnish to the Underwriters, without charge, a copy of
the Registration Statement (including exhibits thereto) and, so long as delivery
of a prospectus by an  underwriter or dealer may be required by the Act, as many
copies of the Prospectus,  any documents  incorporated by reference  therein and
any  amendments  and  supplements  thereto as the  Underwriters  may  reasonably
request.

     5.5 The Company agrees, so long as the Underwritten  Certificates  shall be
outstanding,  or until  such time as the  several  Underwriters  shall  cease to
maintain a secondary  market in the  Certificates,  whichever  first occurs,  to
deliver to the Underwriters  the annual statement as to compliance  delivered to
the Trustee pursuant to Section 3.13 of the Pooling and Servicing  Agreement and
the annual statement of a firm of independent  public  accountants  furnished to
the Trustee pursuant to Section 3.14 of the Pooling and Servicing Agreement,  as
soon as such statements are furnished to the Company.

     5.6 The  Company  will  endeavor to arrange  for the  qualification  of the
Underwritten  Certificates for sale under the laws of such  jurisdictions as the
Underwriters  may reasonably  designate and will maintain such  qualification in
effect so long as required  for the  initial  distribution  of the  Underwritten
Certificates;  provided,  however,  that the  Company  shall not be  required to
qualify to do business in any  jurisdiction  where it is not now so qualified or
to take any action  that would  subject  it to general or  unlimited  service of
process in any jurisdiction where it is not now so subject.

     5.7  Except  as  herein  provided,   the  several   Underwriters  shall  be
responsible only for paying all costs and expenses  incurred by them,  including
the fees and disbursements of their counsel, in connection with the purchase and
sale of the Underwritten Certificates.



                                       10

     5.8 If,  during the period  after the  Closing  Date in which a  prospectus
relating to the Underwritten  Certificates is required to be delivered under the
Act, the Company receives notice that a stop order suspending the  effectiveness
of  the  Registration  Statement  or  preventing  the  offer  and  sale  of  the
Underwritten Certificates is in effect, the Company will advise the Underwriters
of the issuance of such stop order.

     5.9 The Company shall file the Computational  Materials and ABS Term Sheets
(if any) provided to it by the Underwriters under Section 4.2(d) hereof with the
Commission pursuant to a Current Report on Form 8-K by 10:00 a.m. on the morning
the  Prospectus  is  delivered  to  the  Underwriters  or,  in the  case  of any
Collateral  Term Sheet required to be filed prior to such date, by 10:00 a.m. on
the second  business day following the first day on which such  Collateral  Term
Sheet has been sent to a prospective investor;  provided, however, that prior to
such filing of the  Computational  Materials and ABS Term Sheets (other than any
Collateral  Term  Sheets  that are not  based on the  Pool  Information)  by the
Company,  each Underwriter must comply with its obligations  pursuant to Section
4.2 and the  Company  must  receive a letter  from  Deloitte  & Touche,  L.L.P.,
certified public accountants, satisfactory in form and substance to the Company,
GMACCM and their respective  counsels,  to the effect that such accountants have
performed certain specified procedures,  all of which have been agreed to by the
Company,  as a result of which  they  determined  that all  information  that is
included in the Computational Materials and ABS Term Sheets (if any) provided by
the  Underwriters  to the Company for filing on Form 8-K, as provided in Section
4.2 and this  Section  5.9, is accurate  except as to such  matters that are not
deemed by the  Company to be  material.  The  Company  shall file any  corrected
Computational  Materials  described  in  Section  4.2(f) as soon as  practicable
following receipt thereof. The Company also will file with the Commission within
fifteen days of the issuance of the  Certificates  a Current  Report on Form 8-K
(for purposes of filing the Pooling and Servicing Agreement).

     6. Conditions to the  Obligations of the  Underwriters.  The  Underwriters'
obligation  to purchase the  Underwritten  Certificates  shall be subject to the
following conditions:

     6.1  No  stop  order  suspending  the  effectiveness  of  the  Registration
Statement  shall be in effect,  and no  proceedings  for that  purpose  shall be
pending or, to the knowledge of the Company,  threatened by the Commission;  and
the Prospectus  Supplement  shall have been filed or transmitted for filing,  by
means reasonably  calculated to result in a filing with the Commission  pursuant
to Rule 424(b) under the Act.

     6.2 Since January 1, 1999, there shall have been no material adverse change
(not in the  ordinary  course of  business)  in the  condition of the Company or
GMACCM.

     6.3 The Company shall have  delivered to the  Underwriters  a  certificate,
dated the Closing  Date,  of the  President,  a Senior Vice  President or a Vice
President of the Company to the effect that the signer of such  certificate  has
examined this Agreement, the Prospectus, the Pooling and Servicing Agreement and
various other closing  documents,  and that, to the best of his or her knowledge
after reasonable investigation:

     in all material respects; and

          (b) the Company has, in all material  respects,  complied with all the
     agreements  and satisfied all the conditions on its part to be performed or
     satisfied hereunder at or prior to the Closing Date.

     6.4 GMACCM shall have delivered to the  Underwriters  a certificate,  dated
the Closing Date, of the President,  a Senior Vice President or a Vice President
of GMACCM to the effect that the signer of such  certificate  has  examined  the

or  her  knowledge  after  reasonable  investigation,  the  representations  and
warranties  of GMACCM  contained in the Pooling and  Servicing  Agreement and in
this Agreement are true and correct in all material respects.

     6.5 The Underwriters shall have received the opinions of Orrick, Herrington

Date and  substantially  to the effect  set forth in  Exhibit A, the  opinion of

conduct its business, as presently conducted by it.

     6.6 The  Underwriters  shall have  received  from their  counsel an opinion

     6.7 The  Underwriters  shall have received from Deloitte & Touche,  L.L.P.,

been  agreed  to by you,  as a result  of which  they  determined  that  certain
information of an accounting,  financial or statistical  nature set forth in the
Prospectus  Supplement  under the captions  "Description  of the Mortgage  Asset
Pool," "Description of the Certificates" and "Yield and Maturity Considerations"

of the Pooling and  Servicing  Agreement  against  such party.  Such opinion may
express its reliance as to factual  



                                       12

matters on representations  and warranties made by, and on certificates or other

     7. Indemnification and Contribution.

     7.1 The Company and GMACCM,  jointly and severally,  agree to indemnify and
hold  harmless  each  Underwriter  and each person,  if any,  who controls  such
Underwriter  within the meaning of either Section 15 of the Act or Section 20 of
the Securities  Exchange Act of 1934 (the "Exchange Act"),  from and against any
and all losses,  claims,  damages and liabilities caused by any untrue statement
or alleged  untrue  statement of a material fact  contained in the  Registration
Statement for the  registration of the  Underwritten  Certificates as originally
filed or in any  amendment  thereof or other  filing  incorporated  by reference
therein,  or in the  Prospectus or  incorporated  by reference  therein (if used
within the period set forth in Section 5.3 hereof and as amended or supplemented
if the Company shall have furnished any amendments or supplements  thereto),  or
in the Diskette,  or caused by any omission or alleged omission to state therein
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein,  in light of the circumstances  under which they were made,
not misleading,  except insofar as such losses, claims,  damages, or liabilities
are caused by any such untrue  statement or omission or alleged untrue statement
or omission based upon any  information  with respect to which the  Underwriters
have agreed to indemnify the Company pursuant to Section 7.2;  provided that the
Company and GMACCM will be liable for any such loss, claim,  damage or liability
that arises out of or is based upon any such untrue  statement or alleged untrue
statement or omission or alleged  omission made therein relating to the Mortgage
Loan Seller  Information or Pool  Information only if and to the extent that (i)
any such untrue statement is with respect to information  regarding the Mortgage
Loans contained in the Loan Detail or, to the extent  consistent with Annex A to
the Prospectus  Supplement,  the Diskette,  or (ii) any such untrue statement or
alleged  untrue  statement  or omission or alleged  omission is with  respect to
information  regarding  any or all of the Mortgage Loan Sellers or any or all of
the Mortgage  



                                       13
<PAGE>


Loans  contained  in the  Prospectus  Supplement  under  the  headings  "Summary
Information-The  Mortgage  Pool,"  "Risk  Factors-Risks  Related to the Mortgage
Loans"  and/or  "Description  of the  Mortgage  Asset Pool" or on Annex A to the
Prospectus  Supplement  (exclusive  of the Loan  Detail)  and  such  information
represents a restatement of information  contained in the Loan Detail,  or (iii)
any such untrue  statement  or alleged  untrue  statement or omission or alleged
omission is with respect to information  regarding  GMACCM or the Mortgage Loans
contained   in  the   Prospectus   Supplement   under  the   headings   "Summary
Information-The  Mortgage  Pool,"  "Risk  Factors-Risks  Related to the Mortgage
Loans"  and/or  "Description  of the  Mortgage  Asset Pool" or on Annex A to the
Prospectus  Supplement (exclusive of the Loan Detail), and such information does
not represent a restatement  of  information  contained in the Loan Detail;  and
provided that none of the Company,  GMACCM or any Underwriter  will be liable in
any case to the extent that any such loss, claim, damage or liability arises out
of or is based upon any such untrue  statement  or alleged  untrue  statement or
omission or alleged omission made therein relating to the Excluded  Information,
or any information  included in Computational  Materials or ABS Term Sheets that
have been superseded by revised Computational Materials or ABS Terms Sheets (any
such  information,   the  "Excluded  Pool   Information")   provided  that  such
Underwriter has complied with its obligation to circulate revised  Computational
Materials  and ABS Terms  Sheets  in  accordance  with  Section  4.2(e)  and has
delivered  them to the Company no later than one (1) Business Day after delivery
to  investors;  provided,  however,  that each of the Company and GMACCM will be
liable to the extent  any such loss,  claim,  damage or  liability  is caused by
errors in the Pool Information relating to the Mortgage Loans.

     7.2 Each  Underwriter  agrees,  severally  and not jointly to indemnify and
hold harmless the Company,  GMACCM,  their respective  directors or officers and
any person who  controls  the  Company  or GMACCM  within the  meaning of either
Section 15 of the Act or Section 20 of the  Exchange  Act to the same  extent as
the  indemnity  set forth in clause 7.1 above from the Company and GMACCM to the
Underwriters,  but only with respect to (i) the Underwriter Information relating
to such Underwriter or supplied by such Underwriter to the Company for inclusion
in the Prospectus  Supplement and (ii) the Computational  Materials and ABS Term
Sheets delivered to investors in the Certificates by such Underwriter, except to
the extent of any errors in the Computational  Materials or ABS Term Sheets that
are  caused by  errors  in the Pool  Information;  provided,  however,  that the
indemnification  set forth in this  Section 7.2 shall not apply to the extent of
any errors in the Computational  Materials or ABS Term Sheets that are caused by
Excluded Pool  Information  provided that such Underwriter has complied with its
obligation to circulate revised Computational  Materials and ABS Terms Sheets in
accordance  with Section  4.2(e) and has delivered  them to the Company no later
than one (1)  Business  Day  after  delivery  to  investors.  In  addition,  the
Underwriter  agrees to indemnify  and hold harmless the Company,  GMACCM,  their
respective  directors  or officers  and any person who  controls  the Company or
GMACCM  within the meaning of either  Section 15 of the Act or Section 20 of the
Exchange  Act against  any and all  losses,  claims,  damages,  liabilities  and
expenses (including, without limitation,  reasonable attorneys' fees) caused by,
resulting from,  relating to, or based upon any legend regarding  original issue
discount on any Underwritten  Certificate  resulting from incorrect  information
provided  by such  Underwriter  in the  certificates  described  in Section  4.3
hereof.

     7.3 In case any proceeding (including any governmental investigation) shall
be instituted  involving any person in respect of which  indemnity may be sought
pursuant to either  



                                       14
<PAGE>


Section 7.1 or 7.2, such person (the "indemnified  party") shall promptly notify
the person against whom such indemnity may be sought (the "indemnifying  party")
in writing and the indemnifying  party,  upon request of the indemnified  party,
shall  retain  counsel  reasonably  satisfactory  to the  indemnified  party  to
represent  the  indemnified  party and any  others  the  indemnifying  party may
designate in such proceeding and shall pay the reasonable fees and disbursements
of such  counsel  related  to  such  proceeding.  In any  such  proceeding,  any
indemnified  party  shall  have the right to  retain  its own  counsel,  but the
reasonable  fees and  expenses of such  counsel  shall be at the expense of such
indemnified  party unless (i) the indemnifying  party and the indemnified  party
shall have  mutually  agreed to the  retention of such counsel or (ii) the named
parties to any such proceeding  (including any impleaded  parties)  include both
the  indemnifying  party and the indemnified  party and  representation  of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall not, in connection with any proceeding or related  proceedings in the same
jurisdiction,  be liable for the  reasonable  fees and expenses of more than one
separate firm for all such indemnified parties. Such firm shall be designated in
writing by the  Underwriters,  in the case of parties  indemnified  pursuant  to
Section  7.1, and by the Company or GMACCM,  in the case of parties  indemnified
pursuant to Section 7.2. The indemnifying  party may, at its option, at any time
upon  written  notice  to the  indemnified  party,  assume  the  defense  of any
proceeding and may designate counsel reasonably  satisfactory to the indemnified
party in connection  therewith,  provided  that the counsel so designated  would
have no actual  or  potential  conflict  of  interest  in  connection  with such
representation.  Unless  it shall  assume  the  defense  of any  proceeding  the
indemnifying  party shall not be liable for any  settlement  of any  proceeding,
effected  without its written  consent,  but if settled  with such consent or if
there be a final judgment for the plaintiff,  the  indemnifying  party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. If the indemnifying party assumes the defense of
any proceeding,  it shall be entitled to settle such proceeding with the consent
of the  indemnified  party or, if such  settlement  provides  for release of the
indemnified  party in  connection  with all matters  relating to the  proceeding
which have been asserted against the indemnified party in such proceeding by the
other parties to such settlement, without the consent of the indemnified party.

     7.4 If the indemnification provided for in this Section 7 is unavailable to
an indemnified  party under Section 7.1 or 7.2 hereof or insufficient in respect
of any losses,  claims,  damages or  liabilities  referred to therein,  then the
indemnifying  party,  in lieu of  indemnifying  such  indemnified  party,  shall
contribute to the amount paid or payable by such  indemnified  party as a result
of such  losses,  claims,  damages  or  liabilities,  in such  proportion  as is
appropriate  to reflect not only the relative  benefits  received by the Company
and GMACCM on the one hand and the  Underwriters  on the other from the offering
of the Underwritten  Certificates but also the relative fault of the Company and
GMACCM on the one hand and of the  Underwriters  on the other in connection with
the statements or omissions  which resulted in such losses,  claims,  damages or
liabilities,  as  well  as any  other  relevant  equitable  considerations.  The
relative  fault  of the  Company  and  GMACCM  on the one hand and of any of the
Underwriters  on the other shall be  determined  by  reference  to,  among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged  omission to state a material  fact  relates to  information
supplied  by the  Company  or  GMACCM  or by an  Underwriter,  and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent such statement or omission.



                                       15

     7.5 The  Company,  GMACCM and the  Underwriters  agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined by
pro rata  allocation  or by any other method of  allocation  which does not take
account of the considerations  referred to in Section 7.4 above. The amount paid
or payable by an indemnified  party as a result of the losses,  claims,  damages
and  liabilities  referred  to in this  Section 7 shall be  deemed  to  include,
subject  to the  limitations  set  forth  above,  any  legal or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or  defending  any such action or claim except  where the  indemnified  party is
required to bear such  expenses  pursuant to Section  7.4;  which  expenses  the
indemnifying  party  shall  pay as and  when  incurred,  at the  request  of the
indemnified  party, to the extent that the  indemnifying  party believes that it
will be  ultimately  obligated  to pay  such  expenses.  In the  event  that any
expenses so paid by the indemnifying party are subsequently determined to not be
required  to be borne by the  indemnifying  party  hereunder,  the  party  which
received  such  payment  shall  promptly  refund the amount so paid to the party
which  made such  payment.  No person  guilty  of  fraudulent  misrepresentation
(within  the  meaning  of  Section  11(f)  of the  Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.

     7.6 The indemnity and contribution  agreements  contained in this Section 7
and the  representations  and  warranties  of the  Company  and  GMACCM  in this
Agreement shall remain operative and in full force and effect  regardless of (i)
any termination of this Agreement,  (ii) any investigation  made by or on behalf
of an Underwriter or any person controlling an Underwriter or by or on behalf of
the Company or GMACCM and their  respective  directors or officers or any person
controlling the Company or GMACCM and (iii) acceptance of and payment for any of
the Underwritten Certificates.

     8.  Termination.  This Agreement  shall be subject to termination by notice
given to the Company and GMACCM,  if the sale of the  Underwritten  Certificates
provided for herein is not consummated  because of any failure or refusal on the
part of the  Company or GMACCM to comply with the terms or to fulfill any of the
conditions of this  Agreement,  or if for any reason the Company or GMACCM shall
be unable to perform their respective  obligations under this Agreement.  If the
Underwriters  terminate  this  Agreement in accordance  with this Section 8, the
Company  or  GMACCM  will   reimburse  the   Underwriters   for  all  reasonable
out-of-pocket  expenses (including reasonable fees and disbursements of counsel)
that shall have been reasonably  incurred by the Underwriters in connection with
the proposed purchase and sale of the Underwritten Certificates.

     9. Default by an Underwriter. If any Underwriter shall fail to purchase and
pay for any of the  Underwritten  Certificates  agreed to be  purchased  by such
Underwriter hereunder and such failure to purchase shall constitute a default in
the  performance  of  its  obligations  under  this  Agreement,   the  remaining
Underwriters  shall  be  obligated  to take  up and  pay  for  the  Underwritten
Certificates  that the  defaulting  Underwriter  agreed but failed to  purchase;
provided,  however,  that in the  event  that the  initial  principal  amount of
Underwritten  Certificates that the defaulting  Underwriter agreed but failed to
purchase  shall  exceed  10% of the  aggregate  principal  balance of all of the
Underwritten  Certificates  set  forth  in  Schedule  I  hereto,  the  remaining
Underwriters  shall have the right to purchase  all,  but shall not be under any
obligation  to  purchase  any,  of the  Underwritten  Certificates,  and if such
nondefaulting Underwriters do not purchase all of the Underwritten Certificates,
this   Agreement  will  terminate   without   liability  to 



                                       16
<PAGE>


the nondefaulting Underwriters, the Company or GMACCM. In the event of a default
by any  Underwriter  as set forth in this  Section 9, the  Closing  Date for the
Underwritten  Certificates  shall be postponed  for such period,  not  exceeding
seven days, as the nondefaulting  Underwriters shall determine in order that the
required changes in the Registration  Statement,  the Prospectus or in any other
documents or arrangements may be effected.  Nothing  contained in this Agreement
shall  relieve  any  defaulting  Underwriter  of its  liability,  if any, to the
Company  and to any  nondefaulting  Underwriter  for damages  occasioned  by its
default hereunder.

     10. Certain  Representations  and  Indemnities  to Survive.  The respective
agreements, representations, warranties, indemnities and other statements of the
Company,  GMACCM, the Underwriters or the officers of any of the Company, GMACCM
and the  Underwriters  set forth in or made  pursuant  to this  Agreement,  will
remain in full force and effect,  regardless of any investigation,  or statement
as to the results thereof, made by or on behalf of any Underwriter or made by or
on  behalf  of the  Company  or  GMACCM  or any of  their  respective  officers,
directors or controlling  persons,  and will survive delivery of and payment for
the Underwritten Certificates.

     11. Notices. All communications  hereunder will be in writing and effective
only  on  receipt,  and,  if sent to any of the  Underwriters,  will be  mailed,

upon the parties  hereto and their  respective  successors  and the officers and
directors and  controlling  persons  referred to in Section 7 hereof,  and their
successors  and assigns,  and no other person will have any right or  obligation
hereunder.

     13.  Applicable  Law. THIS  AGREEMENT  WILL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS AND DECISIONS OF THE STATE OF NEW YORK.

                [GMAC Commercial Mortgage Corporation Letterhead]

                                                               February __, 1999

To:  Persons Listed on Annex A hereto

                   GMAC Commercial Mortgage Securities, Inc.,
               Mortgage Pass-Through Certificates, Series 1999-C1

Ladies and Gentlemen:

     I am General  Counsel to GMAC  Commercial  Mortgage  Securities,  Inc. (the
"Company")  and  GMAC  Commercial  Mortgage  Corporation  ("GMACCM").   In  that
capacity,  I am  familiar  with the  issuance of certain  Mortgage  Pass-Through
Certificates,   Series  1999-C1  (the   "Certificates"),   evidencing  undivided
interests  in a trust fund (the "Trust  Fund")  consisting  primarily of certain
mortgage  loans (the  "Mortgage  Loans"),  pursuant to a Pooling  and  Servicing
Agreement, dated as of February 1, 1999 (the "Pooling and Servicing Agreement"),
among the Company as depositor,  GMACCM as master servicer and special  servicer
and Norwest Bank Minnesota, National Association, as trustee (the "Trustee").

     Certain of the Mortgage Loans (the "GMACCM  Mortgage Loans") were purchased
by the Company from GMACCM pursuant to, and for the consideration  described in,
the  Mortgage  Loan  Purchase  Agreement,  dated as of  February  2,  1999  (the
"Mortgage Loan Purchase Agreement"),  between GMACCM and the Company. Certain of
the Mortgage  Loans (the "GACC  Mortgage  Loans") were  purchased by the Company
from German American Capital Corporation  ("GACC") pursuant to the Mortgage Loan
Purchase  Agreement,  dated as of  February  2, 1999 (the  "GACC  Mortgage  Loan
Purchase  Agreement"),  between  GACC and the  Company.  Certain of the Mortgage
Loans (the "ML Trust Mortgage Loans") were purchased by the Company from LaSalle
National  Bank as Trustee for  Restructured  Asset  Certificates  With  Enhanced
Returns,  Series  1998-ML  Trust ("ML  Trust")  pursuant  to the  Mortgage  Loan
Purchase  Agreement,  dated as of February 2, 1999 (the "ML Trust  Mortgage Loan
Purchase Agreement"), between ML Trust and the Company.

     The Company  sold a portion of the Class X and all of the Class A-1,  Class
A-2, Class B, Class C, Class D and Class E Certificates to Goldman, Sachs & Co.,
Deutsche  Bank  Securities  Inc.  and  Donaldson,  Lufkin & Jenrette  Securities
Corporation as the underwriters (the  "Underwriters")  named in the Underwriting
Agreement,  dated as of February 2, 1999 (the "Underwriting  Agreement"),  among
the  Company,  GMACCM and the  Underwriters.  The Company  sold a portion of the
Class X to GMACCM pursuant to the Class X Certificate Purchase Agreement,  dated
as of February 2, 1999 (the "Class X Certificate Purchase  Agreement"),  between
the Company  and  GMACCM,  and all of the Class F, Class G, Class H, Class J and
Class K  Certificates  to GMACCM as  initial  purchaser  (in such  capacity,  an
"Initial Purchaser") pursuant to the Certificate Purchase Agreement, dated as of
February 2, 1999 (the "Certificate Purchase Agreement"), between the Company and
GMACCM.  The Company sold the Class R-I, Class R-II and Class R-III Certificates
to  Goldman,  Sachs & Co. as initial  purchaser  (in such  capacity,  an Initial
Purchaser"). The Certificate Purchase Agreement, the 



<PAGE>


Underwriting Agreement,  the Class X Certificate Purchase Agreement,  the GMACCM
Mortgage Loan Purchase Agreement, the GACC Mortgage Loan Purchase Agreement, the
ML  Trust  Mortgage  Loan  Purchase  Agreement  and the  Pooling  and  Servicing
Agreement are collectively  referred to as the  "Agreements".  Capitalized terms
not defined herein have the meanings set forth in the Agreements.

     In  connection  with  rendering  this opinion  letter,  I have examined the
Agreements  and  such  other  records  and  other  documents  as I  have  deemed
necessary.  I have  further  assumed that there is not and will not be any other
agreement  that  materially  supplements  or otherwise  modifies the  agreements
expressed in the  Agreements.  As to matters of fact, I have examined and relied
upon  representations  of parties  contained in the Agreements and, where I have
deemed  appropriate,  representations  and  certifications  of  officers  of the
Company,   GMACCM,  the  Trustee,  other  transaction   participants  or  public
officials.  I have assumed the authenticity of all documents  submitted to me as
originals,  the genuineness of all signatures other than officers of the Company
and GMACCM,  the legal  capacity of natural  persons  other than officers of the
Company  and  GMACCM  and  the  conformity  to the  originals  of all  documents
submitted  to me as copies.  I have  assumed  that all  parties,  except for the
Company and GMACCM,  had the  corporate  power and  authority  to enter into and
perform all obligations thereunder.  As to such parties, I also have assumed the
due  authorization  by all  requisite  corporate  action,  the due execution and
delivery and the  enforceability  of such documents.  I have further assumed the
conformity of the Mortgage Loans and related  documents to the  requirements  of
the Agreements.

     In rendering this opinion letter,  I do not express any opinion  concerning
any law other than the law of the  Commonwealth  of  Pennsylvania,  the  General
Corporation  Law of the State of  Delaware  and the  federal  law of the  United
States,  and I do not express  any opinion  concerning  the  application  of the
"doing business" laws or the securities laws of any jurisdiction  other than the
federal  securities  laws of the United  States.  To the extent  that any of the
matters upon which I am opining herein are governed by laws ("Other Laws") other
than the laws  identified  in the preceding  sentence,  I have assumed with your
permission  and without  independent  verification  or  investigation  as to the
reasonableness   of  such   assumption,   that  such  Other  Laws  and  judicial
interpretation  thereof do not vary in any respect material to this opinion from
the  corresponding  laws  of  the  Commonwealth  of  Pennsylvania  and  judicial
interpretations thereof. I do not express any opinion on any issue not expressly
addressed below.

     Based upon the foregoing, I am of the opinion that:

     1.  The  Company  is  duly  incorporated  and  is  validly  existing  as  a
corporation  in good standing  under the laws of the State of Delaware,  and has
the requisite power and authority, corporate or other, to own its properties and
conduct  its  business,  as  presently  conducted  by it,  and to enter into and
perform its obligations under the Agreements. GMACCM has the requisite power and
authority,  corporate or other, to enter into and perform its obligations  under
the  Agreements.  Each of the Agreements  has been duly and validly  authorized,
executed and  delivered by the Company and GMACCM and,  upon due  authorization,
execution and delivery by the other parties thereto,  will constitute the valid,
legal and binding  agreements  of GMACCM and the  Company,  enforceable  against
GMACCM and the Company in accordance with their terms,  except as enforceability
may  be  limited  by  (i)  bankruptcy,  insolvency,  liquidation,  receivership,
moratorium,  reorganization  or other  similar  laws  affecting  the  rights  of
creditors, 


                                        2

(ii) general principles of equity, whether enforcement is sought in a proceeding
in equity or at law,  and (iii)  public  policy  considerations  underlying  the
securities laws, to the extent that such public policy  considerations limit the
enforceability  of the  provisions  of the  Agreements  which purport to provide
indemnification with respect to securities law violations. No consent, approval,
authorization or order of the  Commonwealth of Pennsylvania,  State of Delaware,
State of California or federal court or governmental  agency or body is required
for the consummation by GMACCM or the Company of the  transactions  contemplated
by  the  terms  of  the  Agreements,   except  for  those  consents,  approvals,
authorizations or orders which previously have been obtained.  Neither the sale,
issuance and delivery of the  Certificates as provided in the Agreements nor the
consummation  of  any  other  of  the  transactions   contemplated  by,  or  the
fulfillment  by the  Company  or  GMACCM  of any  other  of the  terms  of,  the
Agreements,  will result in a breach of any term or  provision of the charter or
bylaws of GMACCM or the Company or any  Commonwealth of  Pennsylvania,  State of
Delaware, or federal statute or regulation or conflict with, result in a breach,
violation or  acceleration  of or  constitute  a default  under the terms of any
indenture  or other  material  agreement  or  instrument  to which GMACCM or the
Company  is a party or by which it is bound or any  order or  regulation  of any
Commonwealth of Pennsylvania or federal court,  regulatory body,  administrative
agency or governmental body having jurisdiction over GMACCM or the Company. This
opinion letter is rendered for the sole benefit of each addressee hereof, and no
other person or entity,  except Orrick,  Herrington & Sutcliffe LLP, is entitled
to rely hereon without my prior written  consent.  Copies of this opinion letter
may not be furnished to any other person or entity,  nor may any portion of this
opinion  letter be  quoted,  circulated  or  referred  to in any other  document
without my prior written consent.

                                             Very truly yours,



                                             Maria Corpora-Buck

A-2,  Class  B,  Class  C,  Class D and  Class  E  Certificates  (together,  the

     (a) The prepayment  assumption  used in pricing the  Certificates  was [ ]%

Certificates  have been sold to the  public  but no single  price is paid for at
least 10% of the  aggregate  actual or notional,  as the case may be,  principal
balance of such class of Certificates,  then the weighted average price at which
the Certificates of such class were sold expressed as a percentage of the actual
or  notional,   as  the  case  may  be,  principal  balance  of  such  class  of
Certificates,  or (iii) if less than 10% of the aggregate actual or notional, as
the case may be,  principal  balance of a class of Certificates has been sold to

February  [___],  1999;  (2) adding  such  estimated  fair  market  value to the
aggregate  purchase price of each class of Certificates  described in clause (i)
or (ii) above; (3) dividing each of the fair market values  determined in clause
(1) by the sum obtained in clause (2); (4) multiplying the quotient obtained for
each  class of  Certificates  in clause  (3) by the  purchase  price paid by the
Purchaser  for all the  Certificates;  and (5) for each  class of  Certificates,
dividing the product  obtained from such class of  Certificates in clause (4) by
the original actual or notional,  as the case may be, principal  balance of such

1.   Representations, Warranties and Covenants.

     1.1 The Company  represents  and warrants to, and agrees with the Purchaser
that:

          (a) The Company has filed with the Securities and Exchange  Commission
     (the "Commission") a registration statement (No. 333-64963) on Form S-3 for
     the registration  under the Securities Act of 1933, as amended (the "Act"),
     of Mortgage Pass-Through  Certificates (issuable in series),  including the
     Publicly  Offered  Certificates,  which  registration  statement has become
     effective,  and a copy  of  which,  as  amended  to the  date  hereof,  has
     heretofore  been delivered to the Purchaser.  The Company  proposes to file
     with the Commission pursuant to Rule 424(b) under the rules and regulations
     of the Commission  under the Act (the "1933 Act  Regulations") a supplement
     dated  February 2, 1999 (the  "Prospectus  Supplement"),  to the prospectus
     dated November 5, 1998 (the "Basic  Prospectus"),  relating to the Publicly
     Offered  Certificates  and  the  method  of  distribution   thereof.   Such
     registration  statement (No. 333-64963)  including exhibits thereto and any
     information  incorporated  therein  by  reference,  as  amended at the date
     hereof,  is  hereinafter  called the  "Registration  Statement;"  the Basic
     Prospectus and the Prospectus  Supplement and any information  incorporated
     therein by reference (including,  without limitation, and only for purposes
     of clarification,  any information filed with the Commission  pursuant to a

     preliminary  form of the Prospectus  Supplement  which has heretofore  been
     filed  pursuant  to  Rule  424,  or  prior  to the  effective  date  of the
     Registration  Statement  pursuant to Rule 402(a),  or 424(a) is hereinafter
     called a "Preliminary  Prospectus Supplement;" and any diskette attached to
     the  Preliminary  Prospectus  Supplement is hereinafter  referred to as the

     initialed on behalf of each Mortgage Loan Seller and the Company).

          (b)  The  Registration   Statement  has  become  effective,   and  the
     Registration Statement as of its effective date (the "Effective Date"), and
     the Prospectus,  as of the date of the Prospectus  Supplement,  complied in
     all material  respects with the applicable  requirements of the Act and the
     1933 Act Regulations;  and the Registration  Statement, as 


                                       2

<PAGE>

     of the Effective  Date, did not contain any untrue  statement of a material
     fact and did not omit to state  any  material  fact  required  to be stated
     therein or necessary to make the statements  therein not misleading and the
     Prospectus and any Diskette,  as of the date of the Prospectus  Supplement,
     did not, and as of the Closing Date will not,  contain an untrue  statement
     of a material  fact and did not and will not omit to state a material  fact
     necessary  in order to make the  statements  therein,  in the  light of the
     circumstances under which they were made, not misleading

          (c) The Company has been duly  incorporated and is validly existing as
     a corporation  in good standing under the laws of the State of Delaware and
     has the requisite  corporate power to own its properties and to conduct its
     business as presently conducted by it.

          (d) This Agreement has been duly authorized, executed and delivered by
     the Company.

          (e)  As of  the  Closing  Date  (as  defined  herein),  the  Purchased
     Certificate  will  conform  in all  material  respects  to the  description
     thereof contained in the Prospectus and the  representations and warranties
     of the  Company in the  Pooling and  Servicing  Agreement  will be true and
     correct in all material respects.

     2. Purchase and Sale.  Subject to the terms and  conditions and in reliance
upon the  representations and warranties herein set forth, the Company agrees to
sell to the  Purchaser,  and the Purchaser  agrees to purchase from the Company,
the Purchased  Certificate  with a Class Notional  Amount of  $667,164,136  at a
price of 4.498540.  There will be added to the purchase  prices of the Purchased
Certificate an amount equal to interest accrued thereon from the Cut-off Date to

     3.  Delivery  and  Payment.  Delivery  of and  payment  for  the  Purchased
Certificate shall be made at the office of Orrick, Herrington & Sutcliffe LLP at
10:00  a.m.,  New York City time,  on February 9, 1999 or such later date as the
Purchaser  shall  designate,  which date and time may be  postponed by agreement
between  the  Purchaser  and the  Company  (such date and time of  delivery  and
payment for the Purchased  Certificate  being herein called the "Closing Date").
Delivery  of the  Purchased  Certificate  (also  referred  to herein as the "DTC
Registered  Certificates") shall be made to the account of the Purchaser through
DTC.

     4. Agreements. The Company agrees with the Purchaser that:

          4.1 Before amending or supplementing the Registration Statement or the
     Prospectus with respect to the Publicly Offered  Certificates,  the Company
     will furnish the Purchaser  with a copy of each such proposed  amendment or
     supplement.

          4.2 The Company will cause the Prospectus Supplement to be transmitted
     to the Commission for filing pursuant to Rule 424(b) under the Act by means
     reasonably  calculated to result in filing with the Commission  pursuant to
     said rule.

     of the Publicly Offered  Certificates in which a prospectus relating to the
     Publicly  Offered  Certificates  is

                                       3

<PAGE>

     required to be  delivered  under the Act,  any event  occurs as a result of
     which it is  necessary  to  amend or  supplement  the  Prospectus,  as then
     amended or supplemented,  in order to make the statements  therein,  in the
     light of the circumstances when the Prospectus is delivered to a purchaser,
     not  misleading,  or if it shall be  necessary to amend or  supplement  the
     Prospectus to comply with the Act or the 1933 Act Regulations,  the Company
     promptly will prepare and furnish,  at its own expense,  to the  Purchaser,
     either  amendments or  supplements to the Prospectus so that the statements
     in the Prospectus as so amended or  supplemented  will not, in the light of
     the  circumstances  when the  Prospectus  is delivered  to a purchaser,  be
     misleading or so that the Prospectus will comply with law.

          4.4 The Company will furnish to the Purchaser,  without charge, a copy
     of the Registration  Statement (including exhibits thereto) and, so long as
     delivery of a prospectus by an underwriter or dealer may be required by the
     Act,  as many  copies of the  Prospectus,  any  documents  incorporated  by
     reference  therein  and  any  amendments  and  supplements  thereto  as the
     Purchaser may reasonably request.

          4.5 The Company agrees,  so long as the Publicly Offered  Certificates
     shall be outstanding,  to deliver to the Purchaser the annual  statement as
     to  compliance  delivered  to the Trustee  pursuant to Section  3.13 of the
     Pooling  and  Servicing  Agreement  and the annual  statement  of a firm of
     independent public accountants furnished to the Trustee pursuant to Section
     3.14 of the Pooling and Servicing Agreement, as soon as such statements are
     furnished to the Company.

          4.6 If, during the period after the Closing Date in which a prospectus
     relating to the Purchased Certificate is required to be delivered under the
     Act,  the  Company  receives  notice  that  a  stop  order  suspending  the
     effectiveness  of the  Registration  Statement or preventing  the offer and
     sale of the Purchased Certificate is in effect, the Company will advise the
     Purchaser of the issuance of such stop order.

     5.  Conditions  to  the  Obligations  of  the  Purchaser.  The  Purchaser's
obligation  to  purchase  the  Purchased  Certificate  shall be  subject  to the
following conditions:

          5.1 No stop order  suspending the  effectiveness  of the  Registration
     Statement shall be in effect,  and no proceedings for that purpose shall be
     pending or, to the knowledge of the Company,  threatened by the Commission;
     and the  Prospectus  Supplement  shall have been filed or  transmitted  for
     filing,  by means  reasonably  calculated  to result  in a filing  with the
     Commission pursuant to Rule 424(b) under the Act.

          5.2 Since January 1, 1999,  there shall have been no material  adverse
     change (not in the ordinary  course of  business)  in the  condition of the
     Company or GMACCM as Master Servicer.

          5.3 The Company shall have  delivered to the Purchaser a  certificate,
     dated the Closing Date, of the President, a Senior Vice President or a Vice
     President of the Company to the effect that the signer of such  certificate
     has examined  this  Agreement,  the  Prospectus,  the Pooling and Servicing
     Agreement and various other closing documents, and that, to the best of his
     or her knowledge after reasonable investigation:

                                       4

<PAGE>

               (a) the  representations  and  warranties  of the Company in this
          Agreement  and in the Pooling  and  Servicing  Agreement  are true and
          correct in all material respects; and

               (b) the Company has, in all material respects,  complied with all
          the  agreements  and  satisfied  all the  conditions on its part to be
          performed or satisfied hereunder at or prior to the Closing Date.

     5.4 [Reserved]

          5.5  The  Purchaser  shall  have  received  the  opinions  of  Orrick,
     Herrington  & Sutcliffe  LLP,  special  counsel for the Company and GMACCM,
     dated the Closing Date and substantially to the effect set forth in Exhibit
     A, the opinion of Maria Corpora-Buck, Esq., general counsel for the Company
     and GMACCM,  dated the  Closing  Date and  substantially  to the effect set
     forth in Exhibit B and the opinion of Severson & Werson, special California
     counsel  for the  GMACCM,  dated  the  Closing  Date  that  GMACCM  is duly
     incorporated  and is validly  existing as a  corporation  in good  standing
     under the laws of the State of California,  and has the requisite power and
     authority,  corporate  or other,  to own its  properties  and  conduct  its
     business, as presently conducted by it.

     Deloitte & Touche,  L.L.P.,  certified public  accountants,  dated the date
     hereof and reasonably  satisfactory in form and substance to the Purchaser,
     to the effect that they have performed certain specified  procedures,  as a
     result of which they determined that certain  information of an accounting,
     financial  or  statistical  nature set forth in the  Prospectus  Supplement
     under the captions  "Description of the Mortgage Asset Pool,"  "Description
     of the  Certificates" and "Yield and Maturity  Considerations"  agrees with

          5.8 The Purchaser shall have received,  with respect to the Trustee, a
     favorable opinion of counsel,  dated the Closing Date, addressing the valid
     existence  of  such  party  under  the  laws  of  the  jurisdiction  of its
     organization, the due authorization,  execution and delivery of the Pooling
     and Servicing Agreement by such party and, subject to standard  limitations
     regarding  laws  affecting  creditors'  rights and  general  principles  of
     equity, the  enforceability of the Pooling and Servicing  Agreement against
     such party.  Such opinion may express its reliance as to factual matters on

     documents  furnished  by officers  and/or  authorized  representatives  of,
     parties to this  Agreement and the Pooling and  Servicing  Agreement and on

     authorization,  execution  and delivery of the  instruments  and  documents
     referred to therein by the parties  thereto  other than the party on behalf
     of which such opinion is being  rendered.  Such opinion may be qualified as
     an  opinion  only on the  laws of each  state in which  the  writer  of the
     opinion is  admitted  to  practice  law and the  federal  law of the United
     States.

          5.9 The  Purchaser  shall have  received  from  Orrick,  Herrington  &
     Sutcliffe LLP, special counsel to the Company, and from Maria Corpora-Buck,
     Esq., general counsel to the Company,  reliance letters with respect to any
     opinions delivered to the rating agencies identified in Section 5.5 herein.

          5.10 The  Purchaser  shall have received from counsel to each Mortgage
     Loan Seller, the opinions  substantially to the effect set forth in Exhibit

     of the GACC  Mortgage  Loan  Purchase  Agreement and Section 8(d) of the ML
     Trust Mortgage Loan Purchase Agreement.

The  Company  will  furnish the  Purchaser  with  conformed  copies of the above
opinions, certificates, letters and documents as they reasonably request.

     6. Indemnification and Contribution.

          6.1 The Company  agrees to indemnify  and hold  harmless the Purchaser
     and each person,  if any, who controls such Purchaser within the meaning of
     either Section 15 of the Act or Section 20 of the  Securities  Exchange Act
     of 1934 (the "Exchange Act"), from and against any and all losses,  claims,
     damages and  liabilities  caused by any untrue  statement or alleged untrue
     statement of a material fact  contained in the  Registration  Statement for
     the registration of the Publicly  Offered  Certificates as originally filed
     or in any  amendment  thereof or other  filing  incorporated  by  reference
     therein, or in the Prospectus or incorporated by reference therein (if used
     within  the  period  set forth in  Section  5.2  hereof  and as  amended or
     supplemented  if  the  Company  shall  have  furnished  any  amendments  or
     supplements  thereto),  or in the  Diskette,  or caused by any  omission or
     alleged  omission to state  therein a material  fact  required to be stated
     therein  or  necessary  to make  the  statements  therein,  in light of the
     circumstances under which they were made, not misleading.

          6.2 In case any proceeding (including any governmental  investigation)
     shall be instituted  involving any person in respect of which indemnity may
     be sought  pursuant to Section 6.1, such person (the  "indemnified  party")
     shall promptly  notify the person against whom such indemnity may be sought
     (the  "indemnifying  party") in writing and the  indemnifying  party,  upon
     request  of  the  indemnified   party,   shall  retain  counsel  reasonably
     satisfactory  to the indemnified  party to represent the indemnified  party
     and any others the indemnifying  party may designate in such proceeding and
     shall pay the reasonable fees and  disbursements of such counsel related to
     such proceeding.  In any such proceeding,  any indemnified party shall have
     the right to retain its own counsel,  but the reasonable  fees and expenses
     of such counsel  shall be at the expense of such  indemnified  party unless
     (i) the  indemnifying  party and the indemnified  party shall have mutually
     agreed to the  retention of such  counsel or (ii) the named  parties to any
     such  proceeding   (including  any  impleaded  parties)  include  both  the
     indemnifying  party and the indemnified  party and  representation  of both
     parties  by the  same  counsel  would be  inappropriate  due to  actual  or
     potential  differing  interests  between them.  It is  understood  that the
     indemnifying  party shall not, in connection with any proceeding or related
     proceedings in the same jurisdiction, be liable for the reasonable fees and
     expenses of more than one separate firm for all such  indemnified  parties.
     Such firm shall be designated in writing by the Purchaser. The indemnifying
     party  may,  at  its  option,  at  any  time  upon  written  notice  to the
     indemnified  party,  assume the defense of any proceeding and may designate
     counsel  reasonably  satisfactory  to the  indemnified  party in

                                       6

<PAGE>

     connection therewith, provided that the counsel so designated would have no
     actual  or  potential   conflict  of  interest  in  connection   with  such
     representation.  Unless it shall assume the defense of any  proceeding  the
     indemnifying   party  shall  not  be  liable  for  any  settlement  of  any
     proceeding,  effected without its written consent, but if settled with such
     consent or if there be a final judgment for the plaintiff, the indemnifying
     party agrees to indemnify the  indemnified  party from and against any loss
     or liability by reason of such settlement or judgment.  If the indemnifying
     party assumes the defense of any proceeding, it shall be entitled to settle
     such  proceeding  with the  consent  of the  indemnified  party or, if such
     settlement provides for release of the indemnified party in connection with
     all matters relating to the proceeding which have been asserted against the
     indemnified  party  in  such  proceeding  by  the  other  parties  to  such
     settlement, without the consent of the indemnified party.

          6.3  The  indemnity  and  contribution  agreements  contained  in this
     Section 7 and the  representations  and  warranties  of the Company in this
     Agreement shall remain operative and in full force and effect regardless of
     (i) any termination of this Agreement, (ii) any investigation made by or on
     behalf  of the  Company  and  its  directors  or  officers  or  any  person
     controlling  the  Company  and  (iii)  acceptance  of and  payment  for the
     Purchased Certificate.

     7.  Termination.  This Agreement  shall be subject to termination by notice
given to the  Company,  if the sale of the  Purchased  Certificate  provided for
herein is not  consummated  because of any failure or refusal on the part of the
Company to comply  with the terms or to fulfill  any of the  conditions  of this
Agreement,  or if for any reason  the  Company  shall be unable to  perform  its
obligations under this Agreement.  If the Purchaser terminates this Agreement in
accordance with this Section 7, the Company will reimburse the Purchaser for all
reasonable  out-of-pocket  expenses (including reasonable fees and disbursements
of  counsel)  that shall  have been  reasonably  incurred  by the  Purchaser  in
connection with the proposed purchase and sale of the Purchased Certificate.

     8. Certain  Representations  and  Indemnities  to Survive.  The  respective
agreements, representations, warranties, indemnities and other statements of the
Company,  the  Purchaser or the officers of any of the Company and the Purchaser
set forth in or made pursuant to this  Agreement,  will remain in full force and
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of any  Purchaser or made by or on behalf of the Company or
any of its  respective  officers,  directors or  controlling  persons,  and will
survive delivery of and payment for the Purchased Certificate.

     9. Notices.  All communications  hereunder will be in writing and effective
only  on  receipt,  if  sent  to the  Company,  will  be  mailed,  delivered  or
telegraphed  and  confirmed to it at 650 Dresher Road,  P.O. Box 1015,  Horsham,

upon the parties  hereto and their  respective  successors  and the officers and
directors and  controlling  


                                       7

     persons referred to in Section 6 hereof,  and their successors and assigns,
     and no other person will have any right or obligation hereunder.

     11.  Applicable  Law. THIS  AGREEMENT  WILL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS AND DECISIONS OF THE STATE OF NEW YORK.

     12.  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
counterparts,  each of which shall be deemed an original,  which taken  together
shall constitute one and the same instrument.

To:  Persons Listed on Annex A hereto

               GMAC Commercial Mortgage Securities, Inc.,
               Mortgage Pass-Through Certificates, Series 1999-C1

Ladies and Gentlemen:

     I am General  Counsel to GMAC  Commercial  Mortgage  Securities,  Inc. (the
"Company")  and  GMAC  Commercial  Mortgage  Corporation  ("GMACCM").   In  that
capacity,  I am  familiar  with the  issuance of certain  Mortgage  Pass-Through
Certificates,   Series  1999-C1  (the   "Certificates"),   evidencing  undivided
interests  in a trust fund (the "Trust  Fund")  consisting  primarily of certain
mortgage  loans (the  "Mortgage  Loans"),  pursuant to a Pooling  and  Servicing
Agreement, dated as of February 1, 1999 (the "Pooling and Servicing Agreement"),
among the Company as depositor,  GMACCM as master servicer and special  servicer
and Norwest Bank Minnesota, National Association, as trustee (the "Trustee").

     Certain of the Mortgage Loans (the "GMACCM  Mortgage Loans") were purchased
by the Company from GMACCM pursuant to, and for the consideration  described in,
the  Mortgage  Loan  Purchase  Agreement,  dated as of  February  2,  1999  (the
"Mortgage Loan Purchase Agreement"),  between GMACCM and the Company. Certain of
the Mortgage  Loans (the "GACC  Mortgage  Loans") were  purchased by the Company
from German American Capital Corporation  ("GACC") pursuant to the Mortgage Loan
Purchase  Agreement,  dated as of  February  2, 1999 (the  "GACC  Mortgage  Loan
Purchase  Agreement"),  between  GACC and the  Company.  Certain of the Mortgage
Loans (the "ML Trust Mortgage Loans") were purchased by the Company from LaSalle
National  Bank as Trustee for  Restructured  Asset  Certificates  With  Enhanced
Returns,  Series  1998-ML  Trust ("ML  Trust")  pursuant  to the  Mortgage  Loan
Purchase  Agreement,  dated as of February 2, 1999 (the "ML Trust  Mortgage Loan
Purchase Agreement"), between ML Trust and the Company.

     The Company sold a portion of the Class X Certificates and all of the Class
A-1, Class A-2,  Class B, Class C, Class D and Class E Certificates  to Goldman,
Sachs & Co.,  Deutsche Bank  Securities  Inc. and  Donaldson,  Lufkin & Jenrette
Securities  Corporation as the underwriters  (the  "Underwriters")  named in the
Underwriting  Agreement,  dated  as  of  February  2,  1999  (the  "Underwriting
Agreement"),  among the Company,  GMACCM and the Underwriters.  The Company sold
the  remaining  portion of the Class X  Certificates  to GMACCM  pursuant to the
Class X Certificate Purchase Agreement, dated as of February 2, 1999 (the "Class
X Certificate Purchase  Agreement"),  between the Company and GMACCM, and all of
the Class F,  Class G, Class H,  Class J and Class K  Certificates  to GMACCM as
initial  purchaser (in such capacity,  an "Initial  Purchaser")  pursuant to the
Certificate  Purchase Agreement,  dated as of February 2, 1999 (the "Certificate
Purchase Agreement"), between the Company and GMACCM. The Company sold the Class
R-I, Class R-II and Class R-III Certificates to Goldman,  Sachs & Co. as initial
purchaser (in such capacity,  an Initial  Purchaser").  The Certificate Purchase
Agreement,   the

Underwriting Agreement,  the Class X Certificate Purchase Agreement,  the GMACCM
Mortgage Loan Purchase Agreement, the GACC Mortgage Loan Purchase Agreement, the
ML  Trust  Mortgage  Loan  Purchase  Agreement  and the  Pooling  and  Servicing
Agreement are collectively  referred to as the  "Agreements".  Capitalized terms
not defined herein have the meanings set forth in the Agreements.

     In  connection  with  rendering  this opinion  letter,  I have examined the
Agreements  and  such  other  records  and  other  documents  as I  have  deemed
necessary.  I have  further  assumed that there is not and will not be any other
agreement  that  materially  supplements  or otherwise  modifies the  agreements
expressed in the  Agreements.  As to matters of fact, I have examined and relied
upon  representations  of parties  contained in the Agreements and, where I have
deemed  appropriate,  representations  and  certifications  of  officers  of the
Company,   GMACCM,  the  Trustee,  other  transaction   participants  or  public
officials.  I have assumed the authenticity of all documents  submitted to me as
originals,  the genuineness of all signatures other than officers of the Company
and GMACCM,  the legal  capacity of natural  persons  other than officers of the
Company  and  GMACCM  and  the  conformity  to the  originals  of all  documents
submitted  to me as copies.  I have  assumed  that all  parties,  except for the
Company and GMACCM,  had the  corporate  power and  authority  to enter into and
perform all obligations thereunder.  As to such parties, I also have assumed the
due  authorization  by all  requisite  corporate  action,  the due execution and
delivery and the  enforceability  of such documents.  I have further assumed the
conformity of the Mortgage Loans and related  documents to the  requirements  of
the Agreements.

     In rendering this opinion letter,  I do not express any opinion  concerning
any law other than the law of the  Commonwealth  of  Pennsylvania,  the  General
Corporation  Law of the State of  Delaware  and the  federal  law of the  United
States,  and I do not express  any opinion  concerning  the  application  of the
"doing business" laws or the securities laws of any jurisdiction  other than the
federal  securities  laws of the United  States.  To the extent  that any of the
matters upon which I am opining herein are governed by laws ("Other Laws") other
than the laws  identified  in the preceding  sentence,  I have assumed with your
permission  and without  independent  verification  or  investigation  as to the
reasonableness   of  such   assumption,   that  such  Other  Laws  and  judicial
interpretation  thereof do not vary in any respect material to this opinion from
the  corresponding  laws  of  the  Commonwealth  of  Pennsylvania  and  judicial
interpretations thereof. I do not express any opinion on any issue not expressly
addressed below.

     Based upon the foregoing, I am of the opinion that:

     1.  The  Company  is  duly  incorporated  and  is  validly  existing  as  a
corporation  in good standing  under the laws of the State of Delaware,  and has
the requisite power and authority, corporate or other, to own its properties and
conduct  its  business,  as  presently  conducted  by it,  and to enter into and
perform its obligations under the Agreements. GMACCM has the requisite power and
authority,  corporate or other, to enter into and perform its obligations  under
the  Agreements.  Each of the Agreements  has been duly and validly  authorized,
executed and  delivered by the Company and GMACCM and,  upon due  authorization,
execution and delivery by the other parties thereto,  will constitute the valid,
legal and binding  agreements  of GMACCM and the  Company,  enforceable  against
GMACCM and the Company in accordance with their terms,  except as enforceability
may  be  limited  by  (i)  bankruptcy,  insolvency,  liquidation,  receivership,
moratorium,  reorganization  or other  similar  laws  affecting  the  rights  of
creditors, 


                                       2

(ii) general principles of equity, whether enforcement is sought in a proceeding
in equity or at law,  and (iii)  public  policy  considerations  underlying  the
securities laws, to the extent that such public policy  considerations limit the
enforceability  of the  provisions  of the  Agreements  which purport to provide
indemnification with respect to securities law violations. No consent, approval,
authorization or order of the  Commonwealth of Pennsylvania,  State of Delaware,
State of California or federal court or governmental  agency or body is required
for the consummation by GMACCM or the Company of the  transactions  contemplated
by  the  terms  of  the  Agreements,   except  for  those  consents,  approvals,
authorizations or orders which previously have been obtained.  Neither the sale,
issuance and delivery of the  Certificates as provided in the Agreements nor the
consummation  of  any  other  of  the  transactions   contemplated  by,  or  the
fulfillment  by the  Company  or  GMACCM  of any  other  of the  terms  of,  the
Agreements,  will result in a breach of any term or  provision of the charter or
bylaws of GMACCM or the Company or any  Commonwealth of  Pennsylvania,  State of
Delaware, or federal statute or regulation or conflict with, result in a breach,
violation or  acceleration  of or  constitute  a default  under the terms of any
indenture  or other  material  agreement  or  instrument  to which GMACCM or the
Company  is a party or by which it is bound or any  order or  regulation  of any
Commonwealth of Pennsylvania or federal court,  regulatory body,  administrative
agency or governmental body having jurisdiction over GMACCM or the Company. This
opinion letter is rendered for the sole benefit of each addressee hereof, and no
other person or entity,  except Orrick,  Herrington & Sutcliffe LLP, is entitled
to rely hereon without my prior written  consent.  Copies of this opinion letter
may not be furnished to any other person or entity,  nor may any portion of this
opinion  letter be  quoted,  circulated  or  referred  to in any other  document
without my prior written consent.

                                                     Very truly yours,



                                                     Maria Corpora-Buck
                                                     General Counsel

<PAGE>


     This  Pooling and  Servicing  Agreement  (this  "Agreement"),  is dated and
effective as of February 1, 1999,  among GMAC  COMMERCIAL  MORTGAGE  SECURITIES,
INC., as Depositor,  GMAC COMMERCIAL MORTGAGE  CORPORATION,  as Master Servicer,
GMAC COMMERCIAL  MORTGAGE  CORPORATION,  as Special  Servicer,  and NORWEST BANK
MINNESOTA, NATIONAL ASSOCIATION, as Trustee.

                             PRELIMINARY STATEMENT:

     The Depositor intends to sell the  Certificates,  to be issued hereunder in
multiple  Classes,  which in the aggregate  will evidence the entire  beneficial
ownership interest in the Trust Fund to be created hereunder, the primary assets
of which will be the Mortgage  Loans.  The aggregate of the initial Cut-off Date
Principal Balances of the Mortgage Loans is approximately $1,334,328,273.

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

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

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

     As provided herein,  the Trustee will elect to treat the segregated pool of
assets  consisting  of the REMIC II  Regular  Interests  as a REMIC for  federal
income tax purposes,  and such  segregated  pool of assets will be designated as
"REMIC  III".  The Class R-III  Certificates  will  represent  the sole class of
"residual  interests"  in REMIC III for purposes of the REMIC  Provisions  under
federal  income  tax  law.  The  following  table  irrevocably  sets  forth  the
designation,  the Pass-Through Rate and initial Class Principal Balance for each
of the Classes of REMIC III Regular Certificates. Determined solely for purposes
of  satisfying  Treasury  Regulation  Section  1.860G-1(a)(4)(iii),  the "latest
possible maturity date" for each Class of REMIC III Regular  Certificates  shall
be the first  Distribution  Date that is at least two years after the end of the
remaining amortization schedule of the Mortgage Loan that has, as of the Closing

obligations, (3) an obligation that has a remaining maturity of greater than 365
days from the date of acquisition thereof. If an obligation is rated by Standard

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

     SECTION 2.01 Establishment of Trust; Conveyance of Mortgage Loans.

     (a) The  Depositor,  concurrently  with the execution and delivery  hereof,
does hereby  establish a trust,  appoint the Trustee to serve as trustee of such
trust  and  assign  to the  Trustee  without  recourse  for the  benefit  of the
Certificateholders all the right, title and interest of the Depositor, including
any security interest therein for the benefit of the Depositor, in, to and under
(i) the Mortgage Loans  identified on the Mortgage Loan Schedule,  (ii) Sections
2, 4(a), 6 and 13 of each Mortgage Loan Purchase Agreement and Sections 2, 4 and
6 of each  Supplemental  Agreement and (iii) all other assets  included or to be
included  in REMIC I.  Such  assignment  includes  all  interest  and  principal
received or  receivable  on or with  respect to the  Mortgage  Loans (other than
payments of principal  and interest due and payable on the Mortgage  Loans on or
before the Cut-off  Date).  The transfer of the  Mortgage  Loans and the related
rights and property accomplished hereby is absolute and, notwithstanding Section
11.07, is intended by the parties to constitute a sale.

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


                                       53
<PAGE>


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

     If any of the  endorsements  referred to in clause (1) of the definition of
"Mortgage  File", or any of the assignments  referred to in clauses (3), (5) and
(7) of the definition of "Mortgage File", are delivered to the Trustee in blank,
the Trustee shall be  responsible  for  completing  the related  endorsement  or
assignment in the name of the Trustee (in such capacity).

     (c) Except under the  circumstances  provided  for in the last  sentence of
this subsection (c), the Trustee shall, as to each Mortgage Loan, at the expense
of the related  Mortgage Loan Seller,  promptly (and in any event within 45 days
of the Closing Date) cause to be submitted for recording or filing,  as the case
may be, in the  appropriate  public  office  for real  property  records  or UCC
Financing Statements, as appropriate, each assignment referred to in clauses (3)
and (5) of the  definition of "Mortgage  File" and each UCC-2 and UCC-3 referred
to in clause (11)(B) of the definition of "Mortgage  File";  provided,  however,
that each  Mortgage  Loan Seller shall have the right to direct the Trustee,  in
writing, to cause the aforementioned


                                       54
<PAGE>


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

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

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

     SECTION 2.02 Acceptance by Trustee.

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

     (b) Within 60 days of the Closing  Date,  the Trustee or a Custodian on its
behalf shall review each of the Mortgage Loan  documents  delivered or caused to
be delivered by the Mortgage Loan Sellers  constituting the Mortgage Files; and,
promptly following such review, the


                                       55
<PAGE>


Trustee shall certify in writing to each of the Depositor,  the Master Servicer,
the Special  Servicer and each  Mortgage  Loan Seller that,  as to each Mortgage
Loan listed in the Mortgage Loan Schedule  (other than any Mortgage Loan paid in
full or any  Mortgage  Loan  specifically  identified  in any  exception  report
annexed thereto as not being covered by such  certification),  (i) all documents
specified in clauses (1), (2), (3), (9) and (12) of the  definition of "Mortgage
File" are in its  possession  or the related  Mortgage Loan Seller has otherwise
satisfied the delivery  requirements in accordance with Section 2.01(b) and (ii)
all documents  delivered or caused to be delivered by the related  Mortgage Loan
Seller  constituting  the related Mortgage File have been reviewed by it or by a
Custodian  on its  behalf  and  appear  regular on their face and relate to such
Mortgage Loan.

     (c) The  Trustee or a  Custodian  on its behalf  shall  review  each of the
Mortgage Loan documents received thereby subsequent to the Closing Date; and, on
or about the first anniversary of the Closing Date, the Trustee shall certify in
writing to each of the Depositor,  the Master Servicer, the Special Servicer and
each  Mortgage Loan Seller that, as to each Mortgage Loan listed on the Mortgage
Loan Schedule (other than any Mortgage Loan as to which a Liquidation  Event has
occurred) and except as specifically  identified in any exception report annexed
to such certification), (i) all documents specified in clauses (1), (2), (9) and
(12) of the  definition of "Mortgage  File" are in its possession or the related
Mortgage  Loan Seller has  otherwise  satisfied  the  delivery  requirements  in
accordance  with  Section  2.01(b),  (ii) it or a  Custodian  on its  behalf has
received  either a recorded  original of each of the  assignments  specified  in
clauses (3) and, insofar as an unrecorded original thereof had been delivered or
caused  to be  delivered  by  the  related  Mortgage  Loan  Seller,  (5)  of the
definition of "Mortgage File" or a copy of such recorded  original  certified by
the  applicable  public  recording  office to be true and complete and (iii) all
Mortgage Loan documents received by it or any Custodian have been reviewed by it
or by such  Custodian on its behalf and appear  regular on their face and relate
to such Mortgage Loan.

     (d) It is acknowledged  that neither the Trustee nor any Custodian is under
any duty or obligation (i) to determine  whether any of the documents  specified
in clauses (4) - (8),  (10),  (11),  (13),  (14) and (15) of the  definition  of
"Mortgage  File" exist or are  required to be delivered  by the  Depositor,  any
Mortgage  Loan Seller or any other Person or (ii) to inspect,  review or examine
any of the documents, instruments,  certificates or other papers relating to the
Mortgage  Loans  delivered  to  it to  determine  that  the  same  are  genuine,
enforceable,  in recordable form or appropriate  for the represented  purpose or
that they are other than what they purport to be on their face.

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


                                       56
<PAGE>


Mortgage Loan Schedule so identified, such new, corrected Mortgage Loan Schedule
shall be deemed to amend and replace the existing Mortgage Loan Schedule for all
purposes.

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

     (a) If the Trustee discovers or receives notice of a Defect in any Mortgage
File or a breach of any representation or warranty set forth in or made pursuant
to Section  4(a) of each  Mortgage  Loan  Purchase  Agreement or Section 2(a) of
either Supplemental Agreement (a "Breach"),  which Defect or Breach, as the case
may be,  materially and adversely  affects the value of any Mortgage Loan or the
interests  of the  Certificateholders  therein,  or if the Trustee  discovers or
receives  notice of any  event  that  would  give  rise to the  repurchase  of a
Mortgage Loan  pursuant to Section 6(b) of any Mortgage Loan Purchase  Agreement
or Section 4(b) of either Supplemental Agreement,  the Trustee shall give prompt
written  notice of such  Defect,  Breach  or  event,  as the case may be, to the
Depositor, the Master Servicer, the Special Servicer and the Rating Agencies and
the related  Mortgage  Loan Seller  (and  GMACCM,  in the case of such a Defect,
Breach or event  under a  Supplemental  Agreement)  and shall  request  that the
related Mortgage Loan Seller (or GMACCM, in the case of such a Defect, Breach or
event under the Supplemental Agreement),  within the time period provided for in
the related  Mortgage  Loan Purchase  Agreement or  Supplemental  Agreement,  as
applicable,  cure  such  Defect,  Breach  or  event,  as the case may be, in all
material  respects or repurchase  the affected  Mortgage Loan at the  applicable
Purchase Price in conformity with the related  Mortgage Loan Purchase  Agreement
or Supplemental  Agreement,  as applicable;  provided,  however, that in lieu of
effecting any such repurchase, a Mortgage Loan Seller (or GMACCM, in the case of
such a  Defect,  Breach  or event  under  the  Supplemental  Agreement)  will be
permitted  until  the  second  anniversary  of the  Closing  Date to  deliver  a
Qualifying  Substitute  Mortgage  Loan  and to pay a cash  amount  equal  to the
applicable Substitution Shortfall Amount, subject to the terms and conditions of
the related  Mortgage  Loan Purchase  Agreement or  Supplemental  Agreement,  as
applicable,  and this Agreement;  provided,  further,  that if such Breach would
cause the Mortgage  Loan to be other than a "qualified  mortgage"  under Section
860G(a)(3) of the Code, such Breach shall be cured or the related  Mortgage Loan
shall be  repurchased  or replaced  with a Qualifying  Substitute  Mortgage Loan
within 90 days of discovery.

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


                                       57
<PAGE>


or event  under the  Supplemental  Agreement)  shall be  entitled  to retain all
amounts received in respect of such Deleted Mortgage Loan.

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

     (b) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan contemplated by this Section 2.03, the Trustee, the Master Servicer and the
Special  Servicer shall each tender promptly to the related Mortgage Loan Seller
(or GMACCM,  as  applicable),  upon delivery to each of the Trustee,  the Master
Servicer  and the Special  Servicer of a trust  receipt  executed by the related
Mortgage Loan Seller (or GMACCM,  as  applicable),  all portions of the Mortgage
File and other  documents  pertaining to such Mortgage Loan possessed by it, and
each  document  that  constitutes  a part of the related  Mortgage File that was
endorsed or assigned to the Trustee  shall be endorsed or assigned,  as the case
may be, to the related  Mortgage Loan Seller (or GMACCM,  as  applicable) in the
same manner as provided in Section 2 of each Mortgage  Loan Purchase  Agreement.
Additionally,  in  connection  with  any  repurchase  of or  substitution  for a
Mortgage Loan pursuant to this Section 2.03,  the Master  Servicer shall release
or cause to be  released  to the related  Mortgage  Loan  Seller (or GMACCM,  as
applicable)  any Reserve  Funds or Escrow  Payments  with respect to the related
Mortgage Loan. If the affected  Mortgage Loan is to be repurchased,  the Trustee
shall  designate  the  Certificate  Account as the account to which funds in the
amount  of the  Purchase  Price are to be wired.

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

     (d) The Trustee shall, for the benefit of the  Certificateholders,  enforce
the  obligations  of each  Mortgage  Loan Seller under  Section 6 of the related
Mortgage Loan Purchase  Agreement and the  obligations of GMACCM under Section 4
of each Supplemental Agreement.


                                       58

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

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

     The Depositor,  as of the Closing Date, and concurrently with the execution
and delivery hereof,  does hereby assign without  recourse all the right,  title
and  interest of the  Depositor  in and to the REMIC I Regular  Interests to the
Trustee  for the benefit of the Class R-II  Certificateholders  and REMIC III as
holder  of  the  REMIC  II  Regular  Interests.  The  Trustee  acknowledges  the
assignment to it of the REMIC I Regular Interests and declares that it holds and
will hold the same in trust for the exclusive use and benefit of all present and
future Class R-II Certificateholders and REMIC III as the holder of the REMIC II

be as set forth in this Agreement.

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

     The Depositor,  as of the Closing Date, and concurrently with the execution

     Concurrently  with the  assignment  to the  Trustee of the REMIC II Regular

Trustee has executed,  and caused the Certificate  Registrar to authenticate and
deliver,  to or upon the order of the Depositor,  the REMIC III  Certificates in
authorized  denominations  evidencing the entire  beneficial  ownership of REMIC

receive  distributions  from the proceeds of REMIC III in respect of their REMIC
III Certificates, and all ownership interests of the respective Classes of REMIC
III  Certificateholders  in and to such distributions,  shall be as set forth in

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

     SECTION 3.01 Servicing and Administration of the Mortgage Loans.

     (a) Each of the Master Servicer and the Special  Servicer shall service and
administer  the Mortgage  Loans that it is  obligated to service and  administer
pursuant to this Agreement on behalf of the Trustee and in the best interests of
and for the  benefit  of the  Certificateholders  (as  determined  by the Master
Servicer  or the  Special  Servicer,  as the case may be, in its good  faith and
reasonable  judgment),  in  accordance  with  applicable  law, the terms of this
Agreement  and the terms of the  respective  Mortgage  Loans and,  to the extent
consistent with the foregoing, further as follows: (i) with the same care, skill
and diligence as is normal and usual in its general  mortgage  servicing and REO
property  management  activities  on  behalf  of third  parties  or on behalf of
itself,  whichever is higher,  with respect to mortgage loans and REO properties
that are comparable to those for which it is responsible hereunder;  (ii) with a
view to the  timely  collection  of all  scheduled  payments  of  principal  and
interest  under the  Mortgage  Loans  or,  if a  Mortgage  Loan  comes  into and
continues  in default and if, in the good faith and  reasonable  judgment of the
Special Servicer, no satisfactory arrangements can be made for the collection of
the delinquent payments,  the maximization of the recovery on such Mortgage Loan
to the  Certificateholders (as a collective whole) on a present value basis (the
relevant discounting


                                       60
<PAGE>


of anticipated  collections that will be distributable to  Certificateholders to
be performed at the related Net Mortgage Rate);  and (iii) without regard to (A)
any relationship that the Master Servicer or the Special  Servicer,  as the case
may be, or any Affiliate  thereof may have with the related  Mortgagor,  (B) the
ownership of any Certificate by the Master Servicer or the Special Servicer,  as
the  case  may  be,  or by any  Affiliate  thereof,  (C) the  Master  Servicer's
obligation to make Advances,  (D) the Special Servicer's  obligation to make (or
to direct the Master Servicer to make) Servicing Advances,  (E) the right of the
Master  Servicer  (or any  Affiliate  thereof) or the Special  Servicer  (or any
Affiliate  thereof),  as the case may be, to receive  reimbursement of costs, or
the sufficiency of any compensation  payable to it, hereunder or with respect to
any particular  transaction and (F) the obligation of GMACCM, as a Mortgage Loan
Seller,  to repurchase  Mortgage  Loans pursuant to Section 6(b) of the Mortgage
Loan Purchase  Agreement or Section 4(b) of either  Supplemental  Agreement (the
conditions set forth in the immediately  foregoing  clauses (i), (ii) and (iii),
the  "Servicing  Standard").  Without  limiting the generality of the foregoing,
each of the  Master  Servicer  and the  Special  Servicer,  in its own name,  in
connection  with its servicing  and  administrative  duties  hereunder is hereby
authorized and empowered by the Trustee to exercise efforts  consistent with the
foregoing   standard   and  to   execute   and   deliver,   on   behalf  of  the
Certificateholders  and the  Trustee  or any of  them,  any  and  all  financing
statements, continuation statements and other documents or instruments necessary
to maintain the lien created by any Mortgage or other  security  document in the
related Mortgage File on the related Mortgaged Property and related  collateral;
subject to Section  3.20,  any and all  modifications,  waivers,  amendments  or
consents to or with respect to any documents  contained in the related  Mortgage
File; and any and all instruments of satisfaction  or  cancellation,  or of full
release or discharge, and all other comparable instruments,  with respect to the
Mortgage Loans and the Mortgaged Properties. Each of the Master Servicer and the
Special  Servicer is also authorized to approve a request by a Mortgagor under a
Mortgage  Loan that it is obligated to service and  administer  pursuant to this
Agreement, for an easement,  consent to alteration or demolition,  and for other
similar matters,  provided that the Master Servicer or the Special Servicer,  as
the case may be, determines,  exercising its good faith business judgment and in
accordance with the Servicing  Standard,  that such approval will not affect the
security  for, or the timely and full  collectability  of, the related  Mortgage
Loan.  Subject  to Section  3.10,  the  Trustee  shall  furnish,  or cause to be
furnished,  to the  Master  Servicer  and the  Special  Servicer  any  powers of
attorney  and other  documents  necessary  or  appropriate  to enable the Master
Servicer or the Special Servicer, as the case may be, to carry out its servicing
and administrative duties hereunder;  provided,  however, that the Trustee shall
not be held  liable,  and shall be  indemnified  by the Master  Servicer  or the
Special Servicer,  as applicable,  for any negligence with respect to, or misuse
of, any such power of attorney by the Master  Servicer or the Special  Servicer,
as the case may be.

     (b)  Subject  to  Section  3.01(a),  the Master  Servicer  and the  Special
Servicer each shall have full power and  authority,  acting alone or, subject to
Section  3.22,  through  Sub-Servicers,  to do or  cause  to be done any and all
things in connection  with such servicing and  administration  which it may deem
necessary or desirable.

     (c) The relationship of the Master Servicer and the Special Servicer to the
Trustee and, unless the same Person acts in both capacities, to each other under
this  Agreement  is  intended  by  the  parties  to be  that  of an  independent
contractor and not that of a joint venturer,  partner or agent.  Unless the same
Person acts in both capacities, the Master Servicer shall have


                                       61
<PAGE>


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

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

     SECTION 3.02 Collection of Mortgage Loan Payments.

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

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

     (a) Each of the Master  Servicer (or the Special  Servicer  with respect to
the Specially  Serviced Mortgage Loans) shall establish and maintain one or more
accounts (the  "Servicing  Accounts"),  into which all Escrow  Payments shall be
deposited  and  retained.   Servicing   Accounts  shall  be  Eligible  Accounts.
Withdrawals  of  amounts so  collected  in  respect  of any  Mortgage  Loan (and
interest  earned  thereon)  from a  Servicing  Account  may be made only to: (i)
effect payment of real estate taxes,  assessments,  insurance  premiums,  ground
rents (if applicable) and comparable  items in respect of the related  Mortgaged
Property;  (ii)  reimburse  the  Trustee,  the Master  Servicer  and the Special
Servicer, in that order, as applicable,  for any unreimbursed Servicing Advances
made thereby to cover any of the items  described in the  immediately  preceding
clause (i); (iii) refund to the related  Mortgagor any sums as may be determined
to be overages;  (iv) pay interest,  if required and as described  below, to the
related Mortgagor on balances in the Servicing Account (or, if and to the extent
not  payable  to the  related  Mortgagor,  to pay such  interest  to the  Master
Servicer or Special Servicer, as applicable); (v) disburse Insurance Proceeds if
required to be applied to the repair or  restoration  of the  related  Mortgaged
Property;  or (vi) clear and terminate the Servicing  Account at the termination
of this  Agreement in  accordance  with Section  9.01.  As part of its servicing
duties,  the Master  Servicer and the Special  Servicer shall pay or cause to be
paid to the  Mortgagors  interest  on funds  in  Servicing  Accounts  maintained
thereby,  to the extent  required  by law or the terms of the  related  Mortgage
Loan. The Servicing Accounts shall not be considered part of the segregated pool
of assets constituting REMIC I, REMIC II, REMIC III or the Grantor Trust.


                                       62
<PAGE>


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

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

     (d) The Master Servicer (or the Special  Servicer with respect to Specially
Serviced Mortgage Loans) shall,  establish and maintain,  as applicable,  one or
more accounts (the "Reserve  Accounts"),  into which all Reserve Funds,  if any,
shall be deposited and retained. Withdrawals of amounts so deposited may be made
to pay for, or to  reimburse  the related  Mortgagor  in  connection  with,  the
related  repairs,   environmental   remediation,   replacements  and/or  capital
improvements at the related  Mortgaged  Property if such repairs,  environmental
remediation,  replacements and/or capital improvements have been completed,  and
such  withdrawals  are made, in accordance  with the Servicing  Standard and the
terms of the related Mortgage Note,  Mortgage and any agreement with the related
Mortgagor  governing  such  Reserve  Funds.  Subject to the terms of the related
Mortgage Note and Mortgage,  all Reserve Accounts shall be Eligible Accounts. As
part of its servicing duties, the Master Servicer and the Special Servicer shall
pay or  cause to be paid to the  Mortgagors  interest  on  funds in the  Reserve
Accounts  maintained  thereby, to the extent required by law or the terms of the
related Mortgage


                                       63

Loan. The Reserve  Accounts shall not be considered  part of the segregated pool
of assets comprising REMIC I, REMIC II, REMIC III or the Grantor Trust.

     SECTION 3.04   Certificate  Account,   Distribution  Account  and  Interest
                    Reserve Account.

     (a) The Master Servicer shall establish and maintain a Certificate  Account
in which the Master  Servicer  shall deposit or cause to be deposited on a daily
basis, except as otherwise  specifically provided herein, the following payments
and collections received or made by or on behalf of it subsequent to the Cut-off
Date (other than in respect of principal and interest on the Mortgage  Loans due
and payable on or before the Cut-off Date),  and payments  (other than Principal
Prepayments)  received by it on or prior to the Cut-off Date but  allocable to a
period subsequent thereto:

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

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

     (iii) any amounts  received from the Special Servicer which are required to
be transferred  from the REO Account  pursuant to Section 3.16(c) and amounts of
interest  and  investment  income  earned in respect of amounts  relating to the
Trust Fund held in any Lock-Box Account or Cash Collateral  Account, if any, and
only to the extent not required to be paid to the applicable Mortgagor under the
terms of the related Mortgage Loan documents or applicable law;

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

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

     (vi) that  portion of each  Delinquency  Advance that  represents  (without
duplication) the Master Servicing Fee and, if applicable,  the Special Servicing
Fee; and

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

     The foregoing  requirements for deposit in the Certificate Account shall be
exclusive,  it being understood and agreed that, without limiting the generality
of the  foregoing,  actual  payments  from  Mortgagors  in the  nature of Escrow
Payments, Reserve Funds, charges for


                                       64
<PAGE>


beneficiary  statements  or demands,  assumption  fees,  amounts  collected  for
mortgagor checks returned for insufficient  funds,  ancillary fees and any other
amounts  that the Master  Servicer  and the Special  Servicer are entitled to as
additional servicing compensation pursuant to Section 3.11 need not be deposited
by the Master Servicer in the Certificate  Account. If the Master Servicer shall
deposit in the  Certificate  Account  any amount not  required  to be  deposited
therein,  it may at any time withdraw such amount from the Certificate  Account,
any provision herein to the contrary notwithstanding.  The Master Servicer shall
promptly deliver to the Special Servicer as additional servicing compensation in
accordance with Section 3.11(d),  assumption fees,  modification fees, ancillary
fees and other  transaction fees due to and received by the Master Servicer with
respect to Specially  Serviced Mortgage Loans. The Certificate  Account shall be
maintained as a segregated account,  separate and apart from trust funds created
for mortgage  pass-through  certificates  of other series serviced and the other
accounts of the Master Servicer.

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

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

     (b) The Trustee shall  establish and maintain the  Distribution  Account in
trust for the benefit of the Certificateholders.  The Distribution Account shall
be maintained as a segregated  account,  separate and apart from trust funds for
mortgage  pass-through  certificates of other series administered by the Trustee
and other accounts of the Trustee.

     The Master  Servicer  shall  deliver to the Trustee each month on or before
the Master  Servicer  Remittance Date therein,  for deposit in the  Distribution
Account,  that portion of the Available  Distribution Amount (calculated without
regard to clause (a)(v), (b)(iii), (b)(iv) or (b)(vi) of the definition thereof)
for the related Distribution Date then on deposit in the Certificate Account.

     In addition,  the Master Servicer  shall,  as and when required  hereunder,
deliver to the Trustee for deposit in the Distribution Account:


                                       65
<PAGE>


     (i) any Delinquency  Advances required to be made by the Master Servicer in
accordance  with  Section  4.03 (in each case,  net of the portion  thereof that
represents  Master Servicing Fees and/or Special  Servicing Fees, which is to be
deposited in the Certificate Account);

     (ii) any Compensating  Interest  Payments required to be made by the Master
Servicer pursuant to Section 3.19;

     (iii) any Liquidation Proceeds paid by the Master Servicer or the Depositor
in  connection  with  the  purchase  of all of the  Mortgage  Loans  and any REO
Properties in the Trust Fund pursuant to Section 9.01 (exclusive of that portion
thereof required to be deposited in the Certificate  Account pursuant to Section
9.01); and

     (iv) any other  amounts  required  to be so  delivered  for  deposit in the
Distribution Account pursuant to any provision of this Agreement.

     The Trustee shall,  upon receipt,  deposit in the Distribution  Account any
and all amounts  received by the Trustee  that are required by the terms of this
Agreement to be deposited  therein.  If, as of 3:00 p.m., New York City time, on
any Master Servicer Remittance Date or on such other date as any amount referred
to in the  foregoing  clauses  (i)  through  (iv) is  required  to be  delivered
hereunder,  the Master  Servicer  shall not have  delivered  to the  Trustee for
deposit in the  Distribution  Account  the  relevant  portion  of the  Available
Distribution  Amount or any of the amounts referred to in the foregoing  clauses
(i) through (iv),  then the Trustee  shall  provide  notice of such failure to a
Servicing  Officer of the Master  Servicer  by  facsimile  transmission  sent to
telecopy no. (215) 328-3478 (or such  alternative  number provided by the Master
Servicer to the Trustee in writing)  and by  telephone  at  telephone  no. (215)
328-1790  (or such  alternative  number  provided by the Master  Servicer to the
Trustee in writing) as soon as possible,  but in any event before 5:00 p.m., New
York City time, on such day.

     Funds  in the  Distribution  Account  may be  invested  by the  Trustee  in
Permitted  Investments  and the  Trustee  shall be required to deposit an amount
equal to the Net Investment Shortfall,  if any, in such account, all as provided
in accordance with the provisions of Section 3.06. The Trustee shall give notice
to the Master  Servicer,  the Special Servicer and the Depositor of the location
of the  Distribution  Account as of the Closing  Date and of the new location of
the Distribution Account prior to any change thereof.

     (c) The Trustee shall  establish and maintain the Interest  Reserve Account
in trust for the benefit of the Certificateholders. The Interest Reserve Account
shall be maintained as a segregated account, separate and apart from trust funds
for  mortgage  pass-through  certificates  of other series  administered  by the
Trustee and other accounts of the Trustee. Funds in the Interest Reserve Account
may be invested in Permitted  Investments  in accordance  with the provisions of
Section 3.06 and the Trustee shall be required to deposit an amount equal to the
Net Investment Shortfall, if any, in such account, all as provided in accordance
with the provisions of Section 3.06.

     On each Master  Servicer  Remittance  Date occurring in (i) January of each
calendar year that is not a leap year and (ii)  February of each calendar  year,
the Trustee shall


                                       66
<PAGE>


calculate  the Withheld  Amount with respect to each  Interest  Reserve Loan. On
each such Master Servicer  Remittance  Date, the Trustee shall withdraw from the
Distribution Account and deposit in the Interest Reserve Account an amount equal
to the  aggregate of the Withheld  Amounts  calculated  in  accordance  with the
previous sentence.  If the Trustee shall deposit in the Interest Reserve Account
any amount not required to be  deposited  therein,  it may at any time  withdraw
such amount from the  Interest  Reserve  Account,  any  provision  herein to the
contrary notwithstanding.  On or prior to the Master Servicer Remittance Date in
March of each  calendar  year,  the Trustee shall  transfer to the  Distribution
Account the aggregate of all Withheld Amounts on deposit in the Interest Reserve
Account. On the Closing Date, the Depositor shall make an initial deposit in the
amount of $462,933 to the  Interest  Reserve  Account,  which  deposit  shall be
treated  as  the  "Withheld  Amounts"  for  purposes  of the  Distribution  Date
occurring in March 1999.

                    Distribution Account and the Interest Reserve Account.

     (a) The Master Servicer may, from time to time, make  withdrawals  from the
Certificate Account for any of the following purposes:

advanced  on or in  respect  of such  Mortgage  Loan or such REO  Loan  that are
allocable as a recovery or advance of interest thereon;

     (iii) to pay to the Special  Servicer,  out of general  collections  on the

     (v) to reimburse the Trustee and itself, in that order, as applicable,  for
unreimbursed  Delinquency  Advances made thereby,  the Master  Servicer's or the
Trustee's  respective rights to be reimbursed  pursuant to this clause (v) being
limited to amounts  received that represent Late  Collections of interest on and
principal of the  particular  Mortgage Loans and REO Loans with respect to which
such Delinquency Advances were made (in each case, net of related Workout Fees);

general collections on the Mortgage Loans and REO Properties;

     (ix) to reimburse  itself (if it is not the affected  Mortgage Loan Seller)
or the Trustee,  as the case may be, for any  unreimbursed  expenses  reasonably
incurred  by such  Person in respect of any  Breach or Defect  giving  rise to a
repurchase  obligation  of a Mortgage Loan Seller under Section 6 of the related
Mortgage  Loan  Purchase   Agreement  (or  Section  4  of  either   Supplemental
Agreement),  including,  without  limitation,  any  expenses  arising out of the
enforcement of the repurchase obligation,  together with interest thereon at the
Reimbursement  Rate, each such Person's right to reimbursement  pursuant to this
clause (ix) with respect to any Mortgage  Loan being  limited to that portion of
the Purchase Price paid for such Mortgage Loan that  represents  such expense in
accordance with clause (c) of the definition of Purchase Price;

     (x) in accordance with Section  2.03(d),  to reimburse the Trustee,  out of
general   collections   on  the  Mortgage  Loans  and  REO  Properties  for  any

     (xiii)  to  pay  to  the  Special   Servicer,   as   additional   servicing
compensation,  all Penalty Charges received on any Specially  Serviced  Mortgage

                                       68
<PAGE>


otherwise  allocable to pay Advance Interest in respect of the related Specially

officers,  employees and agents, as the case may be, out of general  collections

by Section 3.16(a),  (E) the cost of recording this Agreement in accordance with
Section 11.02(a),  and (F) the cost of an Appraisal obtained pursuant to Section
3.11(g) or Section 4.03(c);

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

Distribution Account for any of the following purposes:


                                       69

expenses  relating to tax  audits,  if and to the extent that either (1) none of
the  Trustee,  the Master  Servicer or the Special  Servicer is liable  therefor

failed  to  make  the  required  payment,  and (B)  reimburse  the  Trustee  for
reasonable  expenses  incurred  by  and  reimbursable  to it by the  Trust  Fund
pursuant to Section 10.01(c);

     (vii) to withdraw funds deposited into the  Distribution  Account in error;
and

     (viii) to clear and terminate the  Distribution  Account at the termination

     (c) The Trustee may, from time to time, make  withdrawals from the Interest

     SECTION  3.06  Investment  of  Funds  in  the  Certificate   Account,   the
                    Distribution  Account,  the Interest Reserve Account and the
                    REO Account.

     (a)  (i)  The  Master  Servicer  may  direct  any  depository   institution
maintaining the Certificate Account, any Lock-Box Account or any Cash Collateral
Account  to  invest,  (ii)  the  Special  Servicer  may  direct  any  depository
institution  maintaining  the REO  Account to invest,  or if it is a  depository
institution,  may itself invest, and (iii) the Trustee may direct the depository
institution maintaining the Distribution Account or the Interest Reserve Account
to invest, or if it


                                       70
<PAGE>


is such depository institution, may itself invest, the funds held therein in one
or more  Permitted  Investments  bearing  interest  or sold at a  discount,  and
maturing,  unless  payable  on  demand,  (i) no  later  than  the  Business  Day
immediately  preceding the next succeeding date on which such funds are required
to be withdrawn from such account pursuant to this Agreement,  if a Person other
than the depository institution maintaining such account is the obligor thereon,
and (ii) no later than the next succeeding date on which such funds are required
to be withdrawn from such account pursuant to this Agreement,  if the depository
institution  maintaining such account is the obligor thereon. All such Permitted
Investments shall be held to maturity,  unless payable on demand. Any investment
of funds in an  Investment  Account shall be made in the name of the Trustee (in
its  capacity  as  such).   The  Master  Servicer  (with  respect  to  Permitted
Investments of amounts in the Certificate  Account, any Lock-Box Account and any
Cash  Collateral  Account) and the Special  Servicer  (with respect to Permitted
Investments  of amounts in the REO  Account) on behalf of the  Trustee,  and the
Trustee (with respect to Permitted  Investments  of amounts in the  Distribution
Account and the Interest Reserve Account),  shall (and Trustee hereby designates
the Master Servicer and the Special Servicer, as applicable,  as the Person that
shall) (i) be the  "entitlement  holder" of any Permitted  Investment  that is a
"security  entitlement" and (ii) maintain "control" of any Permitted  Investment
that is either a "certificated  security" or an "uncertificated  security".  For
purposes of this Section  3.06(a),  the terms  "entitlement  holder",  "security
entitlement",  "control",  "certificated security" and "uncertificated security"
shall have the meanings given such terms in Revised Article 8 (1994 Revision) of
the UCC, and "control" of any Permitted Investment by the Master Servicer or the
Special  Servicer  shall  constitute  "control" by a Person  designated  by, and
acting  on  behalf  of the  Trustee  for  purposes  of  Revised  Article 8 (1994
Revision) of the UCC. In the event amounts on deposit in an  Investment  Account
are at any time invested in a Permitted Investment payable on demand, the Master
Servicer (in the case of the Certificate  Account,  any Lock-Box  Account or any
Cash Collateral Account),  the Special Servicer (in the case of the REO Account)
and the  Trustee  (in the  case of the  Distribution  Account  and the  Interest
Reserve Account) shall:

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

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

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


                                       71
<PAGE>


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

     (c)  Except as  otherwise  expressly  provided  in this  Agreement,  if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default  occurs  in any  other  performance  required  under any  Permitted
Investment,  the Trustee may and,  subject to Section 8.02,  upon the request of
Holders of Certificates entitled to a majority of the Voting Rights allocated to
any Class shall take such action as may be  appropriate  to enforce such payment
or  performance,  including  the  institution  and  prosecution  of  appropriate
proceedings.

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

     (a) Each of the Master  Servicer (in the case of Mortgage  Loans other than
Specially  Serviced  Mortgage  Loans) and the Special  Servicer  (in the case of
Specially  Serviced  Mortgage Loans) shall use reasonable  efforts to cause each
Mortgagor to maintain in respect of the related Mortgaged Property all insurance
coverage  as is  required  under  the  related  Mortgage;  provided  that if any
Mortgage  permits the holder  thereof to dictate to the  Mortgagor the insurance
coverage to be maintained on such Mortgaged Property, the Master Servicer or the
Special Servicer,  as appropriate,  shall impose such insurance  requirements as
are consistent  with the Servicing  Standard.  If a Mortgagor  fails to maintain
such insurance, the Master Servicer (at the direction of the Special Servicer in
the case of a  Specially  Serviced  Loan)  shall  (to the  extent  available  at
commercially  reasonable  terms) obtain such  insurance  (which may be through a
master  or  single  interest  policy)  and the cost  (including  any  deductible
relating to such  insurance)  of such  insurance  (or in the case of a master or
single interest policy, the incremental cost (including any deductible  relating
to  such  insurance)  of  such  insurance  relating  to the  specific  Mortgaged
Property),  shall be a Servicing  Advance and shall be recoverable by the Master
Servicer  pursuant to Section  3.05(a).  If at any time a Mortgaged  Property is
located  in an  area  identified  in the  Flood  Hazard  Boundary  Map or  Flood
Insurance Rate Map issued by the Federal  Emergency  Management Agency as having
special flood hazards or it becomes located


                                       72
<PAGE>


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

     (b)  (i)  If the  Master  Servicer  or the  Special  Servicer  obtains  and
maintains  a  blanket  policy  insuring  against  hazard  losses  on  all of the
Mortgaged  Properties and/or REO Properties for which it is responsible to cause
the maintenance of insurance hereunder, then, to the extent such policy provides
protection equivalent to the individual policies otherwise required,  the Master
Servicer or the Special  Servicer,  as the case may be,  shall  conclusively  be
deemed  to have  satisfied  its  obligation  to  cause  hazard  insurance  to be
maintained on such Mortgaged  Properties and/or REO Properties.  Such policy may
contain a deductible clause (not


                                       73
<PAGE>


in excess of a  customary  amount),  in which  case the Master  Servicer  or the
Special Servicer, as appropriate, shall, if there shall not have been maintained
on a Mortgaged  Property or an REO Property a hazard  insurance policy complying
with the requirements of Section 3.07(a),  and there shall have been one or more
losses which would have been covered by such policy,  promptly  deposit into the
Certificate  Account (or into the Servicing Account if insurance proceeds are to
be applied to the repair or restoration of the applicable  Mortgaged Property or
disbursed to the related  Mortgagor) from its own funds the amount not otherwise
payable under the blanket policy because of such deductible clause to the extent
that any such deductible exceeds the deductible limitation that pertained to the
related Mortgage Loan, or, in the absence of any such deductible limitation, the
deductible  limitation  which is  consistent  with the Servicing  Standard.  The
Master Servicer and the Special Servicer each agrees to prepare and present,  on
behalf of itself,  the Trustee  and  Certificateholders,  claims  under any such
blanket policy maintained by it in a timely fashion in accordance with the terms
of such policy.

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

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


                                       74
<PAGE>


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

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

     (a) As to each Mortgage Loan which  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 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
Master  Servicer  or, in the case of a Specially  Serviced  Mortgage  Loan,  the
Special  Servicer,  on behalf of the Trustee as the  mortgagee of record,  shall
exercise (or, subject to Section  3.20(a)(iv),  waive its right to exercise) any
right it may have with  respect  to such  Mortgage  Loan (x) to  accelerate  the
payments  thereon,  or (y) to  withhold  its  consent  to any such sale or other
transfer,  in a manner consistent with the Servicing Standard. In the event that
the Master Servicer or Special  Servicer  intends or is required,  in accordance
with the preceding  sentence,  the Mortgage Loan documents or applicable law, to
permit the  transfer  of any  Mortgaged  Property,  the Master  Servicer  or the
Special Servicer, as the case may be, if consistent with the Servicing Standard,
may enter into an assumption and modification  agreement with the Person to whom
the  related  Mortgaged  Property  has been or is intended to be conveyed or may
enter into substitution of liability  agreement,  pursuant to which the original
Mortgagor  and any original  guarantors  are released  from  liability,  and the
transferee  and any new guarantors  are  substituted  therefor and become liable
under the Mortgage Note and any related guaranties and, in connection therewith,
may require from the related  Mortgagor a reasonable  and  customary fee for the
additional services performed by it, together with reimbursement for any related
costs and expenses incurred by it (but only to the extent that charging such fee
and entering  into such  assumption  and  modification  agreement  will not be a
significant  modification  of the  Mortgage  Loan  for  purposes  of  the  REMIC
Provisions).  The Master Servicer or the Special  Servicer,  as the case may be,
shall promptly notify the Trustee of any such agreement and forward the original
thereof to the Trustee for inclusion in the related  Mortgage  File.  Subject to
Section 3.20(a), if the Master


                                       75
<PAGE>


Servicer or Special  Servicer  intends or is required to permit the  transfer of
any Mortgaged Property and enter into an assumption  agreement or a substitution
of liability  agreement,  as the case may be, in accordance  with the foregoing,
the  Master  Servicer  or the  Special  Servicer,  as the case may be,  prior to
entering into such agreement, shall submit to (A) FITCH IBCA, in the case of any
Mortgage Loan that has, or any Mortgage Loan that is part of a Related  Borrower
Group that has, one of the then-ten highest  outstanding  principal  balances in
the Mortgage Pool;  and (B) Standard & Poor's,  in the case of any Mortgage Loan
that has an  outstanding  principal  balance  in  excess  of the  lesser  of (1)
$20,000,000  or (2)  1.5%  of the  then  outstanding  principal  balance  of the
Mortgage Pool, a copy of such  documentation and any information with respect to
such action as the Master  Servicer or Special  Servicer,  as applicable,  deems
appropriate or as such Rating Agency may reasonably  request,  and shall request
that such Rating Agency deliver to the Master Servicer or Special  Servicer,  as
applicable,  Rating  Agency  Confirmation  with respect to the execution of such
agreement  within  five  (5)  Business  Days  of  receipt  of  a  copy  of  such
documentation  and any  information  such Rating Agency so reasonably  requests;
provided,  however,  if the Master  Servicer or Special  Servicer shall not have
received such written confirmation from FITCH IBCA within five (5) Business Days
of  such  Rating  Agency's  receipt  of a copy of such  documentation  and  such
information, such written confirmation shall be deemed to have been delivered to
the Master Servicer or Special Servicer by FITCH IBCA.

     (b) As to each Mortgage Loan which  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 additional lien or other
encumbrance on the related Mortgaged Property; or

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

then,  for so long as such  Mortgage  Loan is included  in the Trust  Fund,  the
Master  Servicer  or, in the case of a Specially  Serviced  Mortgage  Loan,  the
Special  Servicer,  on behalf of the Trustee as the  mortgagee of record,  shall
exercise (or, subject to Section 3.20(a)(iii),  waive its right to exercise) any
right it may have with  respect  to such  Mortgage  Loan (x) to  accelerate  the
payments  thereon,  or (y) to withhold  its consent to the  creation of any such
additional lien or other encumbrance,  in a manner consistent with the Servicing
Standard;  provided,  however  that the  Master  Servicer  or,  in the case of a
Specially  Serviced  Mortgage  Loan, the Special  Servicer,  shall not waive its
right to  exercise  any such  right  when such  right  arises as a result of the
imposition of a lien against a Mortgaged  Property which lien secures additional
indebtedness  or a mechanic's  or similar lien not  permitted  under the related
Mortgage Loan documents unless, the Master Servicer or the Special Servicer,  as
the case may be, prior to waiving any such right, shall submit to (A) FITCH IBCA
(but only in the case of any Mortgage  Loan that has, or any Mortgage  Loan that
is part of a Related  Borrower  Group  that  has,  one of the  then-ten  highest
outstanding  principal  balances in the Mortgage Pool) and (B) Standard & Poor's
(in all  cases),  a copy of the  documentation  under  which any such lien would
arise together with such other  information with respect to such proposed waiver
as the Master Servicer or Special Servicer, as applicable,  deems appropriate or
as such Rating Agency may reasonably request, and shall request that such Rating
Agency deliver to the Master Servicer or Special Servicer, as applicable,


                                       76
<PAGE>


Rating Agency  Confirmation with respect to such proposed waiver within five (5)
Business  Days of receipt of a copy of such  documentation  and any  information
such Rating  Agency so reasonably  requests;  provided,  however,  if the Master
Servicer or Special  Servicer shall not have received such written  confirmation
from FITCH IBCA within five (5) Business Days of such Rating Agency's receipt of
a copy of such  documentation  and such information,  such written  confirmation
shall be  deemed  to have been  delivered  to the  Master  Servicer  or  Special
Servicer by FITCH IBCA.

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

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

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

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

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

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

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

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

     (viii) The Borrower  shall have  provided  evidence to the Master  Servicer
demonstrating  that the  lien of the  related  Mortgage  is  being  released  to
facilitate the disposition


                                       77
<PAGE>


of the Mortgaged Property or another customary commercial  transaction,  and not
as part of an  arrangement  to  collateralize  the  Certificates  issued  by the
related REMIC with obligations that are not real estate mortgages; and

     (ix) If required by the terms of such Mortgage  Loan,  the Master  Servicer
shall  have  received  Rating  Agency  Confirmation  from each of FITCH IBCA and
Standard & Poor's with respect to the exercise of such Defeasance Option.

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

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

     SECTION 3.09 Realization Upon Defaulted Mortgage Loans.

     (a) The Master Servicer shall notify the Special Servicer of the occurrence
of a  Servicing  Transfer  Event in respect of any  Mortgage  Loan.  The Special
Servicer shall monitor such Specially  Serviced Mortgage Loan,  evaluate whether
the causes of the default can be  corrected  over a  reasonable  period  without
significant impairment of the value of the related Mortgaged Property,  initiate
corrective  action  in  cooperation  with  the  Mortgagor  if,  in  the  Special
Servicer's  judgment,  cure is likely,  and take such other  actions  (including
without limitation,  negotiating and accepting a discounted payoff of a Mortgage
Loan)  as are  consistent  with  the  Servicing  Standard.  If,  in the  Special
Servicer's   judgment,   such  corrective  action  has  been  unsuccessful,   no
satisfactory  arrangement can be made for collection of delinquent payments, and
the  Defaulted  Mortgage Loan has not been released from the Trust Fund pursuant
to any provision hereof, then the Special Servicer shall, subject to subsections
(b) through (d) of this Section 3.09, exercise  reasonable  efforts,  consistent
with the Servicing Standard,  to foreclose upon or otherwise  comparably convert
(which may include an REO Acquisition)  the ownership of property  securing such
Mortgage  Loan.  The foregoing is subject to the provision  that, in any case in
which a Mortgaged  Property shall have suffered damage from an Uninsured  Cause,
the Master  Servicer and the Special  Servicer  shall have the right but not the
obligation to expend its own funds toward the restoration of such property if it
shall  determine in its  reasonable  discretion (i) that such  restoration  will
increase  the  net  proceeds  of  liquidation  of  such  Mortgaged  Property  to
Certificateholders  after  reimbursement  to itself for such expenses,  and (ii)
that such  expenses  will be  recoverable  by the  Master  Servicer  or  Special
Servicer,  as the  case  may be,  out of the  proceeds  of  liquidation  of such
Mortgaged  Property,  as contemplated in Section  3.05(a).  The Special Servicer
(or,  subject to Section  3.19(c),  the Master Servicer) shall advance all other
costs and expenses incurred by it in any such proceedings,  subject to its being
entitled to reimbursement therefor as a Servicing Advance as provided in Section
3.05(a)  and  further  subject to its being  entitled  to pay out of the related
Liquidation  Proceeds  any  Liquidation  Expenses  incurred  in  respect  of any
Mortgage  Loan,  which  Liquidation  Expenses were  outstanding at the time such
proceeds are received. When applicable state law permits the Special Servicer to
select between judicial and non-judicial foreclosure in respect of any


                                       78
<PAGE>


Mortgaged  Property,  the Special Servicer shall make such selection in a manner
consistent with the Servicing  Standard.  Nothing contained in this Section 3.09
shall be construed so as to require the Special Servicer, on behalf of the Trust
Fund, to make a bid on any Mortgaged  Property at a foreclosure  sale or similar
proceeding  that is in  excess of the fair  market  value of such  property,  as
determined by the Special  Servicer in its sole judgment taking into account the
factors  described in Section 3.18(e) and the results of any Appraisal  obtained
pursuant to this Agreement, all such bids to be made in a manner consistent with
the Servicing Standard.  If and when the Master Servicer or the Special Servicer
deems it  necessary  and prudent for  purposes of  establishing  the fair market
value of any Mortgaged  Property securing a Defaulted Mortgage Loan, whether for
purposes of bidding at  foreclosure  or  otherwise,  the Master  Servicer or the
Special  Servicer,  as the  case  may be,  is  authorized  to have an  Appraisal
performed  with respect to such property (the cost of which  Appraisal  shall be
covered by, and reimbursable as, an Additional Trust Fund Expense).

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

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

     (ii) the Special  Servicer  shall have  obtained an Opinion of Counsel (the
cost of which may be withdrawn from the Certificate  Account pursuant to Section
3.05(a)) to the effect that the holding of such  personal  property by the Trust
Fund will not (subject to Section 10.01(f)) cause the imposition of a tax on the
Trust Fund under the REMIC Provisions or cause any of REMIC I, REMIC II or REMIC
III to  fail  to  qualify  as a  REMIC  at any  time  that  any  Certificate  is
outstanding.

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

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


                                       79
<PAGE>


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

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

     (d) If the  environmental  testing  contemplated  by  subsection  (c) above
establishes  that either of the  conditions set forth in clauses (i) and (ii) of
the first sentence  thereof has not been satisfied with respect to any Mortgaged
Property  securing a Defaulted  Mortgage Loan,  then the Special  Servicer shall
take such  action as it deems to be in the best  economic  interest of the Trust
Fund (other than  proceeding to acquire title to the Mortgaged  Property) and is
hereby  authorized  at such time as it deems  appropriate  to  release  all or a
portion of such Mortgaged Property from the lien of the related Mortgage.

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

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

     (g) The Special  Servicer shall have the right to determine,  in accordance
with the Servicing Standard, the advisability of the maintenance of an action to
obtain a deficiency


                                       80
<PAGE>


judgment if the state in which the  Mortgaged  Property is located and the terms
of the Mortgage Loan permit such an action.

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

     SECTION 3.10 Trustee to Cooperate; Release of Mortgage Files.

     (a) Upon the payment in full of any  Mortgage  Loan,  or the receipt by the
Master Servicer or the Special  Servicer of a notification  that payment in full
shall be escrowed in a manner  customary for such purposes,  the Master Servicer
or the Special Servicer, as the case may be, will immediately notify the Trustee
and request  delivery of the related  Mortgage File. Any such notice and request
shall be in the form of a Request for Release signed by a Servicing  Officer and
shall  include a  statement  to the effect  that all  amounts  received or to be
received in  connection  with such payment which are required to be deposited in
the  Certificate  Account  pursuant to Section  3.04(a)  have been or will be so
deposited.  Within seven Business Days (or within such shorter period as release
can reasonably be accomplished  if the Master  Servicer or the Special  Servicer
notifies the Trustee of an exigency) of receipt of such notice and request,  the
Trustee shall release,  or cause any related  Custodian to release,  the related
Mortgage  File  to the  Master  Servicer  or  the  Special  Servicer,  whichever
requested  it.  No  expenses  incurred  in  connection  with any  instrument  of
satisfaction  or deed of  reconveyance  shall be chargeable  to the  Certificate
Account.

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

     (c) Within three  Business Days (or within such shorter  period as delivery
can reasonably be accomplished if the Special  Servicer  notifies the Trustee of
an exigency) of receipt  thereof,  the Trustee  shall execute and deliver to the
Special  Servicer  any court  pleadings,  requests for  trustee's  sale or other
documents  necessary  to the  foreclosure  or  trustee's  sale in  respect  of a
Mortgaged Property or to any legal action brought to obtain judgment against any
Mortgagor on the Mortgage  Note or Mortgage or to obtain a deficiency  judgment,
or to enforce any other  remedies or rights  provided  by the  Mortgage  Note or
Mortgage or otherwise  available at law or in equity. The Special Servicer shall
be responsible  for the  preparation  of all such documents and pleadings.  When
submitted to the Trustee for signature, such documents or


                                       81
<PAGE>


pleadings  shall  be  accompanied  by  a  certificate  of  a  Servicing  Officer
requesting  that such  pleadings  or  documents  be  executed by the Trustee and
certifying  as to the reason such  documents or pleadings  are required and that
the  execution  and  delivery  thereof by the  Trustee  will not  invalidate  or
otherwise affect the lien of the Mortgage,  except for the termination of such a
lien upon completion of the foreclosure or trustee's sale.

     SECTION 3.11 Servicing Compensation; Nonrecoverable Servicing Advances.

     (a) As compensation for its activities hereunder, the Master Servicer shall
be entitled to receive the  Servicing Fee with respect to each Mortgage Loan and
REO Loan. As to each Mortgage Loan and REO Loan,  the Servicing Fee shall accrue
from time to time at the  Servicing  Fee Rate and shall be  computed on the same
basis  and the same  principal  amount  respecting  which any  related  interest
payment  due on such  Mortgage  Loan or  deemed  to be due on such  REO  Loan is
computed.  The Servicing Fee with respect to any Mortgage Loan or REO Loan shall
cease to accrue if a Liquidation Event occurs in respect thereof.  The Servicing
Fee shall be payable monthly, on a loan-by-loan basis, from payments of interest
on each Mortgage Loan,  REO Revenues  allocable as interest on each REO Loan and
the interest portion of Delinquency Advances on each Mortgage Loan and REO Loan.
The Master  Servicer  shall be  entitled  to recover  unpaid  Servicing  Fees in
respect  of any  Mortgage  Loan or REO  Loan  out of  that  portion  of  related
Insurance Proceeds or Liquidation  Proceeds allocable as recoveries of interest,
to the extent permitted by Section  3.05(a).  The right to receive the Servicing
Fee may not be  transferred  in whole or in part except in  connection  with the
transfer of all of the Master Servicer's  responsibilities and obligations under
this Agreement.

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


                                       82
<PAGE>


     (c) As  compensation  for its activities  hereunder,  the Special  Servicer
shall be  entitled to receive the  Special  Servicing  Fee with  respect to each
Specially  Serviced  Mortgage  Loan  and  each REO  Loan.  As to each  Specially
Serviced Mortgage Loan and each REO Loan, the Special Servicing Fee shall accrue
from time to time at the  Special  Servicing  Fee Rate on the same basis and the
same principal amount  respecting which any related interest payment due on such
Specially  Serviced  Mortgage  Loan  or  deemed  to be due on such  REO  Loan is
computed.  The Special  Servicing  Fee with respect to each  Specially  Serviced
Mortgage  Loan  and  each  REO  Loan  shall  cease  to  accrue  as of the date a
Liquidation  Event  occurs in respect  thereof.  As to each  Specially  Serviced
Mortgage Loan and each REO Loan,  earned but unpaid Special Servicing Fees shall
be payable monthly out of general  collections on the Mortgage Loans and any REO
Properties on deposit in the Certificate Account pursuant to Section 3.05(a).

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

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


                                       83
<PAGE>


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

     Subject  to the  Special  Servicer's  right to  employ  Sub-Servicers,  the
Special  Servicer's right to receive the Special  Servicing Fee, the Workout Fee
and/or the  Liquidation Fee may not be transferred in whole or in part except in
connection with the transfer of all of the Special  Servicer's  responsibilities
and obligations under this Agreement.

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

     (e) If the Master  Servicer  or Special  Servicer  is  required  under this
Agreement to make a Servicing Advance,  but neither does so within 15 days after
such  Advance  is  required  to be made,  the  Trustee  shall,  to the  extent a
Responsible  Officer of the Trustee has actual  knowledge of such failure by the
Master Servicer or the Special Servicer to make such Advance (subject to Section
3.11(g) below), make such Advance.

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

     (g) Notwithstanding  anything to the contrary set forth herein, none of the
Master  Servicer,  the Special Servicer or the Trustee shall be required to make
any Servicing Advance that it determines in its reasonable,  good faith judgment
would constitute a Nonrecoverable


                                       84
<PAGE>


Servicing  Advance;  provided,  however,  that the Special  Servicer may make an
Emergency  Advance  notwithstanding  that, at the time such Advance is made, the
Special Servicer may not have adequate information  available in order to make a
determination  whether or not such advance would,  if made, be a  Nonrecoverable
Servicing Advance. In addition, Nonrecoverable Servicing Advances (including any
Emergency  Advances made pursuant to the proviso of the preceding sentence which
are ultimately  determined to be  Nonrecoverable  Servicing  Advances)  shall be
reimbursable pursuant to Section 3.05 out of general collections on the Mortgage
Loans  and  REO  Properties  on  deposit  in  the   Certificate   Account.   The
determination  by the Master  Servicer,  the Special Servicer or, if applicable,
the Trustee,  that it has made a  Nonrecoverable  Servicing  Advance or that any
proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing
Advance,  shall be evidenced by an Officer's  Certificate  delivered promptly to
the Trustee (or, if applicable,  retained  thereby) and the  Depositor,  setting
forth the basis for such determination,  together with (if such determination is
prior to the liquidation of the related Mortgage Loan or REO Property) a copy of
an Appraisal of the related Mortgaged Property or REO Property,  as the case may
be, which shall have been  performed  within the twelve  months  preceding  such
determination,  and further  accompanied  by any other  information,  including,
without  limitation,   engineers'  reports,  environmental  surveys,  inspection
reports,  rent rolls, income and expense statements or similar reports, that the
Master Servicer or the Special Servicer may have obtained and that supports such
determination.  If such an Appraisal  shall not have been required and performed
pursuant  to the terms of this  Agreement,  the  Master  Servicer,  the  Special
Servicer or the Trustee,  as the case may be, may, subject to its reasonable and
good   faith   determination   that  such   Appraisal   will   demonstrate   the
nonrecoverability  of the related Advance,  obtain an Appraisal for such purpose
at the expense of the Trust Fund.  The Trustee  shall be entitled to rely on any
determination  of  nonrecoverability  that  may  have  been  made by the  Master
Servicer or the Special Servicer with respect to a particular Servicing Advance,
and the  Master  Servicer  shall be  entitled  to rely on any  determination  of
nonrecoverability  that may have been made by the Special  Servicer with respect
to a particular Servicing Advance.

     SECTION 3.12 Inspections; Collection of Financial Statements.

     (a) The Master Servicer shall perform (or cause to be performed) a physical
inspection  of  each  Mortgaged   Property  (other  than  Mortgaged   Properties
constituting  collateral for Specially  Serviced  Mortgaged Loans) at such times
and in such manner as are  consistent  with the Servicing  Standard,  but in any
event at least once  every two years (or,  if the  related  Mortgage  Loan has a
current balance of greater than $2,000,000,  at least once every year except, in
the case of a Credit Lease Loan,  at least once every three  years).  The Master
Servicer  shall prepare (or cause to be prepared) a written  report of each such
inspection  detailing the condition of the Mortgaged Property and specifying the
existence  of (i) any  vacancy  in the  Mortgaged  Property  evident  from  such
inspection that the Master Servicer deems material,  (ii) any sale,  transfer or
abandonment of the Mortgaged  Property evident from such  inspection,  (iii) any
adverse change in the condition or value of the Mortgaged  Property evident from
such  inspection  that the Master  Servicer  deems  material,  or (iv) any waste
committed on the Mortgaged  Property  evident from such  inspection.  The Master
Servicer, upon request, shall deliver to the Trustee a copy of each such written
report.  In the event the  published  rating  for any  Tenant  or  Guarantor  is
downgraded  by any of  Standard  & Poor's  or FITCH  IBCA by one or more  rating
increments  (e.g. AA to A) and no inspection has been performed due to a ratings
downgrade in the  preceding  twelve months for the related  Mortgaged  Property,
then in each such instance, the Master Servicer or


                                       85
<PAGE>


Special Servicer, as applicable,  shall cause all Mortgaged Properties leased to
such Tenant to be inspected as soon as reasonably practical and, thereafter,  in
accordance with the first sentence of this clause (a).

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

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

     SECTION 3.13 Annual Statement as to Compliance.

     Each of the Master  Servicer and the Special  Servicer  will deliver to the
Trustee,  with a copy to the  Depositor,  on or before  April 30th of each year,
beginning in 2000, an Officer's  Certificate  stating, as to the signer thereof,
that (i) a review  of the  activities  of the  Master  Servicer  or the  Special
Servicer,  as the case may be,  during the  preceding  calendar  year and of its
performance under this Agreement has been made under such officer's supervision,
(ii) to the best of such officer's  knowledge,  based on such review, the Master
Servicer  or the  Special  Servicer,  as the case may be, has  fulfilled  in all
material respects its obligations under this Agreement throughout such year, or,
if  there  has  been a  default  in the  fulfillment  of  any  such  obligation,
specifying  each such  default  known to such  officer and the nature and status
thereof and (iii) the Master Servicer or the Special  Servicer,  as the case may
be, has received no notice regarding  qualification,  or challenging the status,
of the Trust Fund as a REMIC or of the Grantor Trust as a "grantor  trust" under
the Grantor  Trust  Provisions  from the Internal  Revenue  Service or any other
governmental  agency or body or, if it has received any such notice,  specifying
the details  thereof.  A copy of such Officer's  Certificate  may be obtained by
Certificateholders  upon written request to the Trustee pursuant to Section 8.12
hereof.


                                       86

     SECTION 3.14 Reports by Independent Public Accountants.

     On or  before  April  30th of each  year,  beginning  in 2000,  the  Master
Servicer at its expense  shall cause a firm of  independent  public  accountants
(which may also  render  other  services to the Master  Servicer)  and that is a
member of the American  Institute of Certified  Public  Accountants to furnish a
statement  to the  Trustee  and to the  Depositor  to the effect that (i) it has
obtained  a  letter  of  representation   regarding  certain  matters  from  the
management of the Master  Servicer,  which includes an assertion that the Master
Servicer has complied with certain minimum mortgage loan servicing standards (to
the extent applicable to commercial and multifamily mortgage loans),  identified
in the Uniform Single  Attestation  Program for Mortgage Bankers  established by
the Mortgage  Bankers  Association of America,  with respect to the servicing of
commercial and  multifamily  mortgage  loans during the most recently  completed
calendar year and (ii) on the basis of an examination  conducted by such firm in
accordance  with standards  established  by the American  Institute of Certified
Public  Accountants,  such  representation  is  fairly  stated  in all  material
respects,  subject  to such  exceptions  and  other  qualifications  that may be
appropriate.  In rendering its report such firm may rely, as to matters relating
to the  direct  servicing  of  commercial  and  multifamily  mortgage  loans  by
Sub-Servicers,  upon comparable reports of firms of independent certified public
accountants  rendered on the basis of examinations  conducted in accordance with
the same  standards  (rendered  within one year of such  report) with respect to
those Sub-Servicers.

     The Special  Servicer will deliver an annual  accountants'  report only if,
and in such form as may be, requested by the Rating Agencies.

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

     SECTION 3.15 Access to Certain Information.

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

     SECTION 3.16 Title to REO Property; REO Account.

     (a) If title to any REO Property is acquired,  the deed or  certificate  of
sale  shall  be  issued  to  the  Trustee  or  its  nominee  on  behalf  of  the
Certificateholders.  The Special  Servicer,  on behalf of the Trust Fund,  shall
attempt to sell any REO Property prior to the close of the third taxable year of
the Trust Fund following the taxable year in which the Trust Fund acquires


                                       87
<PAGE>


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

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

     (c) The Special  Servicer  shall cause all funds  necessary  for the proper
operation,  management,  maintenance,  disposition  and  liquidation  of any REO
Property to be withdrawn from the REO Account, but only to the extent of amounts
on deposit in the REO Account relating to such REO Property. Within one Business
Day following the end of each  Collection  Period,  the Special  Servicer  shall
withdraw  from the REO  Account  and  deposit  into the  Certificate  Account or
deliver to the Master  Servicer  (which  shall  deposit  such  amounts  into the
Certificate  Account) the  aggregate of all amounts  received in respect of each
REO Property during such Collection  Period,  net of any withdrawals made out of
such amounts pursuant to


                                       88
<PAGE>


Section 3.16 (b) or this Section 3.16(c); provided that the Special Servicer may
retain in the REO Account  such portion of proceeds  and  collections  as may be
necessary to maintain a reserve of  sufficient  funds for the proper  operation,
management,  maintenance and disposition of the related REO Property  (including
without   limitation   the  creation  of  a  reasonable   reserve  for  repairs,
replacements and necessary  capital  improvements  and other related  expenses),
such  reserve  not to exceed  an amount  sufficient  to cover  such  items to be
incurred during the following twelve-month period.

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

     SECTION 3.17 Management of REO Property; Independent Contractors.

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

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

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

     (iii)  Directly  Operating  such  property as REO Property  could result in
income subject to an REO Tax and, in the good faith and  reasonable  judgment of
the Special Servicer, that no commercially feasible means exists to operate such
property as REO Property without the Trust Fund incurring or possibly  incurring
an REO Tax on income from such property,  the Special  Servicer shall deliver to
the Trustee,  in writing,  a proposed plan (the "Proposed  Plan") to manage such
property as REO Property.  Such plan shall include  potential sources of income,
and to the extent commercially feasible,  estimates of the amount of income from
each such source. Within a reasonable period of time after receipt of such plan,
the Trustee shall consult with the Special Servicer and shall advise the Special
Servicer of the Trust Fund's federal income tax reporting  position with respect
to the  various  sources of income  that the Trust Fund would  derive  under the
Proposed Plan. In addition,  the Trustee shall (to the maximum extent  possible)
advise the Special Servicer of the estimated amount of taxes that the Trust Fund
would


                                       89
<PAGE>


be required to pay with respect to each such source of income.  After  receiving
the information  described in the two preceding sentences from the Trustee,  the
Special  Servicer shall either (A) implement the Proposed Plan (after  acquiring
the  respective  Mortgaged  Property as REO  Property) or (B) manage and operate
such property in a manner that would not result in the  imposition of an REO Tax
on the income derived from such property.

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

     (b) If title to any REO Property is acquired,  the Special  Servicer  shall
manage,  conserve,  protect and operate such REO Property for the benefit of the
Certificateholders  solely for the purpose of its prompt disposition and sale in
a  manner  that  does  not  cause  such  REO  Property  to  fail to  qualify  as
"foreclosure  property" within the meaning of Section 860G(a)(8) of the Code or,
except as permitted by Section 3.17(a),  result in the receipt by the Trust Fund
of any  "income  from  non-permitted  assets"  within  the  meaning  of  Section
860F(a)(2)(B) of the Code or any "net income from foreclosure property" which is
subject  to  taxation  under the REMIC  Provisions.  Subject  to the  foregoing,
however,  the Special Servicer shall have full power and authority to do any and
all things in connection  therewith as are in the best  interests of and for the
benefit of the  Certificateholders (as determined by the Special Servicer in its
good faith and reasonable  judgment) and, consistent  therewith,  shall withdraw
from the REO Account,  to the extent of amounts on deposit  therein with respect
to each REO  Property,  funds  necessary for the proper  operation,  management,
maintenance and disposition of such REO Property, including, without limitation:

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

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

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

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


                                       90
<PAGE>


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

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

     (i) the terms and  conditions of any such contract may not be  inconsistent
herewith and shall reflect an agreement reached at arm's length;

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

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

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

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

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

     SECTION 3.18 Sale of Defaulted Mortgage Loans and REO Properties.

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

     (b) In the event that any Mortgage  Loan becomes a Defaulted  Mortgage Loan
and the  Special  Servicer  has  determined  in good faith  that such  Defaulted
Mortgage  Loan will  become  subject to  foreclosure  proceedings,  the  Special
Servicer shall promptly so notify, in


                                       91
<PAGE>


writing,  the Master Servicer and the Trustee,  and the Trustee shall so notify,
in  writing,  within 10 days after  receipt of its  notice,  the  Holders of the
Controlling Class. The Majority  Certificateholder  of the Controlling Class may
at its (or their)  option  purchase from the Trust Fund, at a price equal to the
Purchase  Price,  any such  Defaulted  Mortgage Loan. The Purchase Price for any
Defaulted  Mortgage  Loan  purchased  hereunder  shall  be  deposited  into  the
Certificate Account, and the Trustee,  upon receipt of an Officer's  Certificate
from the Master  Servicer to the effect that such  deposit has been made,  shall
release  or  cause  to be  released  to the  Majority  Certificateholder  of the
Controlling Class (or any designee thereof) the related Mortgage File, and shall
execute and deliver such  instruments  of transfer or  assignment,  in each case
without   recourse,   as   shall   be   necessary   to  vest  in  the   Majority
Certificateholder  of the Controlling Class (or any designee thereof)  ownership
of such  Defaulted  Mortgage  Loan. In connection  with any such  purchase,  the
Special   Servicer   shall   deliver   the   related   Credit   File   to   such
Certificateholder(s).

     (c) If the  Majority  Certificateholder  of the  Controlling  Class has not
purchased  any  Defaulted  Mortgage  Loan within 15 days of its having  received
notice in respect thereof pursuant to the immediately  preceding subsection (b),
either the Special  Servicer or, subject to the Special  Servicer's prior rights
in such  regard,  the Master  Servicer  may at its option,  within 15 days after
receipt of such notice,  purchase  such  Defaulted  Mortgage Loan from the Trust
Fund,  at a price  equal to the  Purchase  Price.  The  Purchase  Price  for any
Defaulted  Mortgage  Loan  purchased  hereunder  shall  be  deposited  into  the
Certificate Account, and the Trustee,  upon receipt of an Officer's  Certificate
from the Master  Servicer to the effect that such  deposit has been made,  shall
release or cause to be released to the Master Servicer or the Special  Servicer,
as  applicable,  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 necessary to vest in the Master Servicer
or the Special  Servicer,  as  applicable,  such  Defaulted  Mortgage  Loan.  In
connection with any such purchase by the Master  Servicer,  the Special Servicer
shall deliver the related Credit File to the Master Servicer.

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

     The Special  Servicer  shall use  reasonable  efforts to solicit offers for
each REO Property in such manner as will be reasonably  likely to realize a fair
price within the time period


                                       92
<PAGE>


provided for by Section  3.16(a).  The Special  Servicer  shall accept the first
(and,  if  multiple  bids  are  contemporaneously  received,  highest)  cash bid
received from any Person that constitutes a fair price for such REO Property. If
the Special Servicer determines, in its good faith and reasonable judgment, that
it will be unable to realize a fair price for any REO  Property  within the time
constraints imposed by Section 3.16(a),  then the Special Servicer shall dispose
of such REO  Property  upon such terms and  conditions  as the Special  Servicer
shall deem  necessary and  desirable to maximize the recovery  thereon under the
circumstances and, in connection therewith, shall accept the highest outstanding
cash bid, regardless of from whom received.

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

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

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


                                       93
<PAGE>


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

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

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

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

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

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

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


                                       94
<PAGE>


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

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

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

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


                                       95
<PAGE>


Mortgaged  Property,  unless an Appraisal  thereof had previously  been obtained
within the prior twelve months.  The cost of such Appraisal shall be covered by,
and reimbursable as, a Servicing Advance.

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

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

     (f) The Master  Servicer  shall  deliver to the  Trustee for deposit in the
Distribution  Account on each Master Servicer Remittance Date, without any right
of reimbursement  therefor,  an amount equal to the sum of (A) the lesser of (i)
the aggregate of all Prepayment  Interest Shortfalls incurred in connection with
Principal Prepayments received in respect of the Mortgage Loans (other than Late
Due Date Mortgage Loans) during the most recently ended Collection  Period,  and
(ii) the aggregate  Master Servicing Fees received by the Master Servicer during
such  Collection  Period and (B) the aggregate of all  Extraordinary  Prepayment
Interest Shortfalls,  if any, incurred in connection with Principal  Prepayments
received in respect of Late Due Date  Mortgage  Loans  during the most  recently
ended Collection Period.

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

     (h)  Subject to Section  3.20(a)(iv),  with  respect to all ARD Loans,  the
Master Servicer and the Special  Servicer shall not take any enforcement  action
with  respect to the payment of Excess  Interest or  principal  in excess of the
principal  component of the  constant  Monthly  Payment,  other than request for
collection,  until the maturity date of the related Mortgage Loan. The foregoing
shall not limit the Servicer and Special  Servicer's  obligation to establish or
direct the related Mortgagor to establish a Lock-Box Account pursuant to Section
3.24.  The Master  Servicer  shall,  within 90 days of the Startup Day provide a
legally  effective  waiver to any such  Mortgagor such that the Revised Rate for
such  Mortgage  Loan shall not exceed the  related  initial  Mortgage  Rate plus
2.00%.

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


                                       96

     SECTION 3.20 Modifications, Waivers, Amendments and Consents.

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

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

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

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

     (iv)  neither the Master  Servicer nor the Special  Servicer  shall make or
permit any modification,  waiver or amendment of any term of, or take any of the
other acts referenced in this Section 3.20(a) or clause (h) of Section 3.19 with
respect  to, any  Mortgage  Loan that would (A) cause REMIC I, REMIC II or REMIC
III to fail to  qualify  as a REMIC  under  the  Code  or  (subject  to  Section
10.01(f))  result in the imposition of any tax on "prohibited  transactions"  or
"contributions"  after  the  Startup  Day of any  such  REMIC  under  the  REMIC
Provisions or (B) cause any Mortgage Loan to cease to be a "qualified  mortgage"
within  the  meaning  of  Section  860G(a)(3)  of the Code  (neither  the Master
Servicer  nor the  Special  Servicer  shall be liable for  judgments  as regards
decisions made under this subsection which were made


                                       97
<PAGE>


in good faith and, unless it would  constitute bad faith or negligence to do so,
each of the Master  Servicer  and the Special  Servicer  may rely on opinions of
counsel in making such decisions);

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

     (vi) neither the Master Servicer nor the Special  Servicer shall release or
substitute  any  collateral  securing  an  outstanding  Mortgage  Loan except as
provided in Sections  3.08 and 3.09(d) and except in the case of a release where
(A) the use of the collateral to be released will not, in the Master  Servicer's
or Special Servicer's,  as the case may be, good faith and reasonable  judgment,
materially and adversely  affect the Net Operating  Income being generated by or
the  use of  the  related  Mortgaged  Property,  (B)  there  is a  corresponding
principal  paydown of such  Mortgage  Loan in an amount at least  equal to, or a
delivery of substitute collateral with an appraised value at least equal to, the
appraised  value of the collateral to be released,  (C) the remaining  Mortgaged
Property and any substitute  collateral is, in the Master  Servicer's or Special
Servicer's,  as the case may be, good faith and  reasonable  judgment,  adequate
security  for  the  remaining   Mortgage  Loan  and  (D)  such  release   and/or
substitution would not, in and of itself, result in the downgrade, qualification
(including by placement on "negative  credit watch") or withdrawal of the rating
then assigned by any Rating Agency to any Class of Certificates (as confirmed in
writing by each Rating Agency);

provided that (x) the  limitations,  conditions  and  restrictions  set forth in
clauses (i) through (vi) above shall not apply to any  modification  of any term
of any Mortgage Loan or any other acts  referenced in this Section  3.20(a) that
is required  under the terms of such Mortgage Loan in effect on the Closing Date
and  that is  solely  within  the  control  of the  related  Mortgagor,  and (y)
notwithstanding  clauses (i) through (vi) above, neither the Master Servicer nor
the Special  Servicer shall be required to oppose the  confirmation of a plan in
any  bankruptcy  or  similar  proceeding  involving  a  Mortgagor  if  in  their
reasonable and good faith judgment such opposition would not ultimately  prevent
the confirmation of such plan or one substantially  similar.  Neither the Master
Servicer nor the Special  Servicer may extend the Maturity  Date on any Mortgage
Loan except pursuant to this Section 3.20(a) or as otherwise  required under the
related loan documents.

     (b) Neither the Master  Servicer  nor the Special  Servicer  shall have any
liability to the Trust Fund, the  Certificateholders  or any other Person if its

                                       98

reasonably  likely to  produce a greater  recovery  to  Certificateholders  on a
present  value  basis  than  would  liquidation,  should  prove  to be  wrong or
incorrect,  so long as the analysis and determination  were made on a reasonable
basis in good faith by the Master  Servicer or Special  Servicer  and the Master
Servicer or Special  Servicer was not  negligent in  ascertaining  the pertinent
facts.

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

     (d) The Master Servicer and, with respect to a Specially Serviced Mortgaged
Loan, the Special  Servicer each may, as a condition to its granting any request
by a Mortgagor  for consent,  modification,  waiver or  indulgence  or any other
matter or thing,  the granting of which is within the Master  Servicer's  or the

unpaid  principal  balance  of the  related  Mortgage  Loan) for the  additional
services  performed in connection  with such request,  together with any related
costs and expenses incurred by it.

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

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

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

     (a) Upon  determining  that a Servicing  Transfer  Event has occurred  with
respect to any Mortgage Loan and if the Master  Servicer is not also the Special
Servicer,  the Master Servicer shall promptly give notice  thereof,  and deliver
the related  Servicing  File, to the Special  Servicer and shall use  reasonable
efforts to provide the Special  Servicer  with all  information,  documents  (or

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

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

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

     SECTION 3.22 Sub-Servicing Agreements.

     (a) The  Master  Servicer  and the  Special  Servicer  may each  enter into
Sub-Servicing  Agreements for the servicing and  administration of all or a part
of the Mortgage Loans for which it is responsible  hereunder,  provided that, in
each  case,  the  Sub-Servicing  Agreement:  (i) is not  inconsistent  with this
Agreement  and shall  provide that the  Sub-Servicer  will  maintain  errors and
omissions  insurance  and  fidelity  bond  coverage  as  required  of the Master
Servicer or the Special  Servicer  (whichever  retained  it) under  Section 3.07
hereof;  (ii) provides that if the Master Servicer or the Special  Servicer,  as
the case may be,  shall  for any  reason no longer  be the  Master  Servicer  or
Special Servicer, as applicable,  hereunder (including,  without limitation,  by
reason of an Event of Default or their termination hereunder),  the Trustee, its
designee or any  successor  Master  Servicer or Special  Servicer may  thereupon
assume all of the rights and,  except to the extent they arose prior to the date
of assumption,  obligations of the Master Servicer or the Special  Servicer,  as
the case may be,  under  such  agreement;  (iii) in the case of a  Sub-Servicing
Agreement entered into by the Master Servicer, expressly or effectively provides
that (if the


                                      100
<PAGE>


Master Servicer and the Special Servicer are not the same Person) such agreement
shall  terminate  with respect to any Mortgage Loan  serviced  thereunder at the
time such  Mortgage  Loan  becomes a  Specially  Serviced  Mortgage  Loan;  (iv)
requires that the Master Servicer  consent to any modification to the terms of a

any such  Sub-Servicing  Agreement  shall not be an  obligation  of, or  expense
chargeable  to, the  Certificateholders  or the Trust Fund.  References  in this
Agreement to actions taken or to be taken by the Master  Servicer or the Special
Servicer,  as the  case  may be,  include  actions  taken  or to be  taken  by a
Sub-Servicer  on behalf of the Master Servicer or the Special  Servicer,  as the
case  may  be;  and,  in  connection  therewith,  all  amounts  advanced  by any
Sub-Servicer  to satisfy the  obligations of the Master  Servicer or the Special
Servicer,  as the  case  may  be,  hereunder  to  make  Servicing  Advances  and
Delinquency  Advances  shall be  deemed  to have  been  advanced  by the  Master
Servicer or the Special Servicer,  as the case may be, out of its own funds and,
accordingly, such Advances shall be recoverable by such Sub-Servicer in the same
manner  and out of the  same  funds  as if such  Sub-Servicer  were  the  Master
Servicer or the Special  Servicer,  as the case may be, and, for so long as they
are outstanding,  such Advances shall accrue interest in accordance with Section
3.11(f) or Section 4.03(d), as applicable, such interest to be allocable between
the  Master  Servicer  or the  Special  Servicer,  as the case may be,  and such
Sub-Servicer  as they may agree.  For  purposes  of this  Agreement,  the Master
Servicer  and the Special  Servicer  each shall be deemed to have  received  any

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

     (d) In the event the Trustee, its designee or any successor Master Servicer
or Special Servicer assumes the rights and obligations of the Master Servicer or
the Special Servicer under any Sub-Servicing  Agreement,  the Master Servicer or
the Special Servicer,  as the case may be, at its expense shall, upon request of
the Trustee, deliver to the assuming party all documents and records relating to
such  Sub-Servicing  Agreement  and  the  Mortgage  Loans  then  being  serviced

thereunder,  and  otherwise  use  reasonable  efforts to effect the  orderly and
efficient transfer of the Sub-Servicing Agreement to the assuming party.

     (e)  Notwithstanding any Sub-Servicing  Agreement,  the Master Servicer and
the Special  Servicer each shall remain  obligated and liable to the Trustee and
the  Certificateholders  for the  servicing and  administration  of the Mortgage

under  the  same  terms  and  conditions  as  if it  alone  were  servicing  and

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

     The  Certificateholders  entitled  to more  than 50% of the  Voting  Rights
allocated  to the  Controlling  Class,  may at any time  and  from  time to time
replace any existing  Special Servicer or any Special Servicer that has resigned
or  otherwise  ceased  to serve  as  Special  Servicer.  Such  Holders  shall so
designate  a Person  to so serve by the  delivery  to the  Trustee  of a written
notice  stating  such  designation,  subject to the  confirmation  of the Rating
Agencies. The Trustee shall, promptly after receiving any such notice, so notify
the Rating Agencies.  The designated Person shall become the Special Servicer as
of the date the Trustee shall have received:  (i) written  confirmation from the
Rating Agencies  stating that if the designated  Person were to serve as Special
Servicer hereunder,  none of the then-current ratings of the outstanding Classes
of the  Certificates  would be  qualified  (including  by placement on "negative
credit  watch"),  downgraded  or  withdrawn;  (ii) a written  acceptance  of all
obligations  of the  Special  Servicer  under this  Agreement,  executed  by the
designated Person; and (iii) an Opinion of Counsel (at the expense of the Person
designated  to  become  the  Special  Servicer  or the  Holders  that  made  the
designation)  to the  effect  that the  designation  of such  Person to serve as
Special  Servicer  is in  compliance  with  this  Section  3.23  and  all  other
applicable provisions of this Agreement, that upon the execution and delivery of
the written acceptance referred to in the immediately preceding clause (ii), the
designated  Person shall be bound by the terms of this  Agreement  and that this
Agreement shall be enforceable  against the designated Person in accordance with
its  terms.  The  existing  Special  Servicer  shall be deemed to have  resigned
simultaneously  with such  designated  Person's  becoming  the Special  Servicer
hereunder;  provided,  however,  that (i) the resigning  Special  Servicer shall
continue to be entitled to receive all amounts accrued or owing to it under this
Agreement  on or prior to the  effective  date of such  resignation,  whether in
respect of  Servicing  Advances  or  otherwise,  and (ii) it and its  directors,
officers,  employees and agents shall continue to be entitled to the benefits of
Section 6.03,  notwithstanding  any such  resignation.  Such  resigning  Special
Servicer shall cooperate with the Trustee and the replacement  Special  Servicer
in   effecting   the   termination   of   the   resigning   Special   Servicer's
responsibilities  and  rights  hereunder,  including,  without  limitation,  the
transfer  within two  Business  Days to the  replacement  Special  Servicer  for
administration  by it of all cash  amounts  that  shall at the time be or should
have been  deposited in the REO Account or delivered by the Special  Servicer to
the Master  Servicer or that are  thereafter  received with respect to Specially
Serviced Mortgage Loans and REO Properties.

                                      102
<PAGE>


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

                    the Special Servicer.

     GMACCM,  in its  capacity as both  Master  Servicer  and  Special  Servicer

with the laws of each State in which any  Mortgaged  Property  is located to the
extent necessary to perform its obligations under this Agreement.

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

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

     (iv) This Agreement, assuming due authorization,  execution and delivery by
the other parties hereto,  constitutes a valid,  legal and binding obligation of
GMACCM,  enforceable against GMACCM in accordance with the terms hereof, subject
to (A) applicable bankruptcy, insolvency,  reorganization,  moratorium and other
laws affecting the enforcement of creditors' rights  generally,  and (B) general
principles of equity,  regardless of whether such enforcement is considered in a
proceeding in equity or at law.

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


                                      103
<PAGE>


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

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

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

the extent not  previously  deemed paid, for all prior  Distribution  Dates with
such payments allocated among the REMIC II Regular Interests such that remaining

subsequent  adjustments  made on such  Distribution  Date under Section  4.01(c)

Certificates on such Distribution Date under Section 4.01(c) below.

     On each  Distribution  Date,  the  Trustee  shall pay to the Holders of the
Class R-II Certificates,  in accordance with Section 4.01(c),  that portion,  if
any, of the REMIC II  Distribution  Amount for such date that has not  otherwise

of this Section 4.01(b) (such portion,  the "Class R-II Distribution Amount" for
such Distribution Date).

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

     (c) On each Distribution  Date,  following the deemed payments to REMIC III
in respect of the REMIC II Regular  Interests  on such date  pursuant to Section

Distribution Dates;

     (ii) to pay  principal  first to the Holders of the Class A-1  Certificates
and second to the Holders of the Class A-2 Certificates,  in each case, up to an
amount equal to the lesser of (1) the then outstanding  Class Principal  Balance
of such Class of  Certificates  and (2) the remaining  portion,  if any, of such
Principal Distribution Amount;

     (iii)  to  reimburse  the  Holders  of the  respective  Classes  of Class A
Certificates,  up to an amount  equal to and pro rata as among  such  Classes in

Fund  Expenses,   if  any,  previously  deemed  allocated  to  such  Classes  of
Certificates and for which no reimbursement has previously been paid; and

     (iv) to make  payments  on the  Subordinated  Certificates  pursuant to the
following paragraph;

provided  that,  on each  Distribution  Date  after the  aggregate  of the Class
Principal  Balances of the  Subordinated  Certificates has been reduced to zero,
and in any event on the Final Distribution Date, the payments of principal to be
made  pursuant  to clause  (ii)  above,  will be so made to the  Holders  of the
respective  Classes of Class A  Certificates,  up to an amount equal to, and pro
rata as among such Classes in accordance  with, the respective then  outstanding
Class  Principal  Balances  of  such  Classes  of  Certificates.  References  to

provided that, on the Final  Distribution  Date, the payments of principal to be

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

     On each  Distribution  Date, the Trustee shall withdraw any amounts then on
deposit in the Distribution Account that represent Prepayment Premiums collected
during or prior to the  related  Collection  Period  and shall  distribute  such
amounts,  in each case, subject to available funds, as additional  interest,  as
follows:

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

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

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

     On each Distribution Date, the Trustee shall withdraw from the Distribution
Account,  as Grantor Trust Assets,  any amounts that represent  Excess  Interest
actually collected on the ARD Loans and any related REO Loans during the related
Collection  Period and shall  distribute  with respect to their interests in the
Grantor  Trust,  such  amounts  to the  holders  of the Class K-1  Certificates,
without  regard to  whether  any such  Class is  entitled  to  distributions  of
interest or principal on such  Distribution Date (whether by reason of its Class
Principal  Balance  having been  reduced to zero,  by reason of it not yet being
entitled to distributions of principal, or for any other reason).

     (d) All distributions  made with respect to each Class on each Distribution
Date shall be  allocated  pro rata among the  outstanding  Certificates  in such
Class based on their


                                      110
<PAGE>


respective  Percentage  Interests.  Except  as  otherwise  provided  in the last
paragraph of Section 4.01(c) or as provided below, all such  distributions  with
respect  to  each  Class  on  each  Distribution  Date  shall  be  made  to  the
Certificateholders of the respective Class of record at the close of business on
the  related  Record  Date and  shall be made by wire  transfer  of  immediately
available funds to the account of any such  Certificateholder at a bank or other
entity having appropriate facilities therefor, if such  Certificateholder  shall
have  provided the Trustee with wiring  instructions  no less than five Business
Days prior to the related Record Date (which wiring  instructions  may be in the
form of a standing  order  applicable to all subsequent  Distribution  Dates) or
otherwise by check mailed to the address of such Certificateholder as it appears
in  the  Certificate  Register.  The  final  distribution  on  each  Certificate
(determined without regard to any possible future  reimbursement of any Realized
Loss or Additional Trust Fund Expense previously  allocated to such Certificate)
will be made in like manner,  but only upon  presentation  and surrender of such
Certificate at the offices of the  Certificate  Registrar or such other location
specified in the notice to  Certificateholders  of such final distribution.  Any
distribution  that is to be made with respect to a Certificate in  reimbursement
of a  Realized  Loss or  Additional  Trust  Fund  Expense  previously  allocated
thereto,  which  reimbursement  is  to  occur  after  the  date  on  which  such
Certificate is surrendered as  contemplated by the preceding  sentence,  will be
made by check mailed to the address of the  Certificateholder  that  surrendered
such  Certificate as such address last appeared in the Certificate  Registrar or
to any other address of which the Trustee was subsequently notified in writing.

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

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

     (g) Except as  otherwise  provided in Section  9.01,  whenever  the Trustee
expects that the final  distribution  with respect to any Class of  Certificates
(determined without regard to any possible future  reimbursement of any Realized
Loss or  Additional  Trust Fund  Expense  previously  allocated to such Class of
Certificates) will be made on the next Distribution Date, the


                                      111
<PAGE>


Trustee shall,  as soon as  practicable in the month in which such  Distribution
Date occurs, mail to each Holder of such Class of Certificates as of the date of
mailing a notice to the effect that:

     (i) the Trustee  expects that the final  distribution  with respect to such
Class of  Certificates  will be made on such  Distribution  Date  but only  upon
presentation  and  surrender  of  such   Certificates  at  the  offices  of  the
Certificate Registrar or such other location therein specified, and

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

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

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

                    Master Servicer and the Special Servicer.

respective Schedules Q thereto at the times required by the Code or the Internal
Revenue  Service,  and shall  provide  from time to time  such  information  and

Residual Certificates may reasonably request.

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

shall be entitled to indicate the source of all information furnished by it, and
the Trustee may affix thereto any  disclaimer it deems  appropriate  in its sole
discretion  (together with any warnings as to the confidential nature and/or the
uses  of  such  information  as  it  may,  in  its  sole  discretion,  determine
appropriate),  (C) the Trustee  may notify  Certificateholders  and  Certificate
Owners of the  availability of any such  information in any manner as it, in its
sole  discretion,  may  determine,  (D) the Trustee  shall be entitled  (but not
obligated) to require  payment from each  recipient of a reasonable fee for, and
its  out-of-pocket   expenses  incurred  in  connection  with,  the  collection,
assembly,  reproduction  or delivery  of any such  Additional  Information,  (E)
without the consent of the Depositor,  the Trustee may, in its sole  discretion,
furnish  Additional  Information to a Rating Agency in any instance,  and to the
Certificateholders,   Certificate  Owners  and/or  the   public-at-large  if  it
determines  that  the  furnishing  of  such  information  would  assist  in  the
evaluation of the investment characteristics or valuation of the Certificates or
would be in the best  interests  of the  Certificateholders  or is  required  by
applicable  law and (F) the  Trustee  shall be entitled  to  distribute  or make
available such Additional  Information in accordance with such reasonable  rules
and procedures as it may deem  necessary or  appropriate  (which may include the
requirement  that an agreement  that  provides  such  information  shall be used

the Certificates be executed by the recipient,  if and to the extent the Trustee
deems  the  same to be  necessary  or  appropriate).  Nothing  herein  shall  be
construed to impose upon the Trustee any obligation or duty to furnish or

distribute  any Additional  Information  to any Person in any instance,  and the
Trustee shall neither have any liability for furnishing nor for refraining  from
furnishing Additional Information in any instance. The Trustee shall be entitled

     related  borrower is required by the Mortgage to deliver and does  deliver,
     or  otherwise  agrees  to  provide  and does  provide,  such  information),
     presenting  the  computation   made  in  accordance  with  the  methodology
     described in Exhibit F to  "normalize"  the full year net operating  income

Mortgage  Loan  Schedule),  and (iii)  whether such Tenant or Guarantor has been
placed on credit watch by any Rating Agency.

     Not later than the first day of the calendar  month  following  each Master
Servicer  Remittance  Date,  the Master  Servicer shall forward to the Trustee a
statement,  setting forth the status of the Certificate  Account as of the close
of  business  on  such  Master  Servicer   Remittance  Date,  stating  that  all
remittances  to the Trustee  required by this Agreement to be made by the Master
Servicer  have been made (or, in the case of any such required  remittance  that

thereof)  and  showing,  for the  period  from  the  preceding  Master  Servicer

     The obligation of the Master Servicer to deliver the reports required to be
delivered  by it  pursuant  to this  subsection  (b) is  subject  to the  Master
Servicer  having  received  from the  Special  Servicer  in a timely  manner the
related  reports  and  information  necessary  or  required to enable the Master
Servicer to prepare and deliver such reports.  The Master  Servicer shall not be

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

     (c) On the second Business Day after each  Determination  Date, the Special
Servicer  shall  forward to the Master  Servicer,  for each  Specially  Serviced

required  to allow the Master  Servicer to perform  its  obligations  under this

     SECTION 4.03 Delinquency Advances.

     (a) On each Delinquency  Advance Date, the Master Servicer shall either (i)
deposit into the  Certificate  Account from its own funds an amount equal to the
aggregate amount of Delinquency  Advances,  if any, to be made in respect of the
related  Distribution  Date, (ii) apply amounts held in the Certificate  Account
for future distribution to  Certificateholders in subsequent months in discharge
of any such obligation to make Delinquency  Advances,  or (iii) make Delinquency
Advances in the form of any  combination of (i) and (ii)  aggregating  the total
amount of Delinquency  Advances to be made;  provided that, if Late  Collections
(net of related  Workout  Fees) of the  delinquent  Monthly  Payments  for which
Delinquency  Advances are to be made for the related  Distribution  Date, are on
deposit in the  Certificate  Account and  available to make such  Advances,  the
Master  Servicer  shall  utilize  such Late  Collections  to make such  Advances
pursuant to clause (ii) above.  Any amounts held in the Certificate  Account for
future  distribution  and  so  used  to  make  Delinquency   Advances  shall  be
appropriately  reflected  in the Master  Servicer's  records and replaced by the
Master  Servicer  by  deposit in the  Certificate  Account on or before the next
succeeding Determination Date (to the extent not previously replaced through the
deposit of Late Collections of the delinquent  principal and interest in respect
of which such  Delinquency  Advances were made).  If, as of 3:00 p.m.,  New York
City


                                      120
<PAGE>


time,  on any  Master  Servicer  Remittance  Date,  the  Trustee  shall not have
received  any  Delinquency  Advance  required to be made by the Master  Servicer
pursuant  to this  Section  4.03(a)  (and the  Master  Servicer  shall  not have
delivered to the Trustee the requisite  Officer's  Certificate and documentation
related to a determination of nonrecoverability of a Delinquency Advance),  then
the Trustee shall provide  notice of such failure to a Servicing  Officer of the
Master  Servicer by facsimile  transmission  sent to telecopy no. (215) 328-3478
(or such  alternative  number  provided by the Master Servicer to the Trustee in
writing) and by telephone at telephone  no. (215)  328-1790  (Attention:  Master
Servicing  Manager) (or such alternative  number provided by the Master Servicer
to the  Trustee in writing) as soon as  possible,  but in any event  before 5:00
p.m., New York City time, on such day. If after such notice the Trustee does not
receive the full  amount of such  Delinquency  Advances by 11:00 a.m.,  New York
City time,  on the  Business  Day  immediately  following  such Master  Servicer
Remittance  Date,  then the Trustee  shall make the portion of such  Delinquency
Advances  that was  required  to be, but was not,  made by the  Master  Servicer
pursuant to this Section 4.03(a).

     (b) The aggregate  amount of Delinquency  Advances to be made by the Master
Servicer  in respect  of the  Mortgage  Loans  (including,  without  limitation,
Assumed  Monthly  Payments for Balloon  Mortgage  Loans  delinquent  as to their
respective  Balloon  Payments) and any REO Loans for any Distribution Date shall
equal,  subject to subsection (c) below,  the aggregate of all Monthly  Payments
(other than Balloon Payments) and any Assumed Monthly Payments, in each case net
of related Workout Fees payable  hereunder,  that were due or deemed due, as the
case may be, in respect  thereof on their  respective  Due Dates during the same
month as such  Distribution  Date and that  were not paid by or on behalf of the
related  Mortgagors  or  otherwise  collected as of the close of business on the
later of the related Due Date or the last day of the related  Collection Period;
provided  that,  if an  Appraisal  Reduction  Amount  exists with respect to any
Required Appraisal Loan, then, in the event of subsequent delinquencies thereon,
the  interest  portion of the  Delinquency  Advance in respect of such  Required
Appraisal  Loan for the  related  Distribution  Date shall be reduced  (it being
herein acknowledged that there shall be no reduction in the principal portion of
such Delinquency Advance) to equal the product of (i) the amount of the interest
portion of such  Delinquency  Advance for such Required  Appraisal Loan for such
Distribution Date without regard to this proviso, multiplied by (ii) a fraction,
expressed  as a  percentage,  the  numerator  of which  is  equal to the  Stated
Principal  Balance of such Required  Appraisal  Loan  immediately  prior to such
Distribution  Date, net of the related  Appraisal  Reduction Amount, if any, and
the  denominator  of  which is equal to the  Stated  Principal  Balance  of such
Required Appraisal Loan immediately prior to such Distribution Date.

     (c) Notwithstanding anything herein to the contrary, no Delinquency Advance
shall be required to be made hereunder if such  Delinquency  Advance  would,  if
made,   constitute   a   Nonrecoverable   Delinquency   Advance.   In  addition,
Nonrecoverable  Delinquency  Advances shall be reimbursable  pursuant to Section
3.05(a) out of general  collections  on the Mortgage Loans and REO Properties on
deposit in the Certificate Account. The determination by the Master Servicer or,
if  applicable,  the  Trustee,  that it has  made a  Nonrecoverable  Delinquency
Advance or that any proposed  Delinquency  Advance,  if made, would constitute a
Nonrecoverable   Delinquency  Advance,   shall  be  evidenced  by  an  Officer's
Certificate  delivered  promptly  (and, in any event,  in the case of a proposed
Delinquency Advance to be made by the Master Servicer, no less than two Business
Days prior to the related  Delinquency  Advance Date) by the Master  Servicer to
the Trustee (or, if applicable, retained thereby) and the Depositor,


                                      121
<PAGE>


setting  forth  the  basis  for  such  determination,  together  with  (if  such
determination  is prior to the  liquidation of the related  Mortgage Loan or REO
Property)  a copy of an  Appraisal  of the  related  Mortgaged  Property  or REO
Property,  as the case may be, which shall have been performed within the twelve
months  preceding  such  determination,  and  further  accompanied  by any other
information  that the Master Servicer or the Special  Servicer may have obtained
and that supports such  determination.  If such an Appraisal shall not have been
required  and  performed  pursuant  to the terms of this  Agreement,  the Master
Servicer,  the Special Servicer or the Trustee, as the case may be, may, subject
to its  reasonable  and  good  faith  determination  that  such  Appraisal  will
demonstrate the  nonrecoverability  of the related Advance,  obtain an Appraisal
for such purpose at the expense of the Trust Fund. The Trustee shall be entitled
to rely on any determination of nonrecoverability that may have been made by the
Master Servicer or the Special Servicer with respect to a particular Delinquency
Advance,  and the Master Servicer shall be entitled to rely on any determination
of  nonrecoverability  that may have  been  made by the  Special  Servicer  with
respect to a particular Delinquency Advance.

     (d) The Master  Servicer and the Trustee  shall each be entitled to receive
interest at the Reimbursement  Rate in effect from time to time,  accrued on the
amount of each  Delinquency  Advance  made thereby (out of its own funds) for so
long as such Delinquency  Advance is outstanding (or, if any Delinquency Advance
is  required  to be made in  respect  of a  delinquent  Monthly  Payment  on any
Mortgage Loan prior to the end of the grace period for such Monthly Payment, for
so long as such  Delinquency  Advance is  outstanding  following the end of such
grace period),  payable first,  out of Penalty Charges  received on the Mortgage
Loan or REO Loan as to which such  Delinquency  Advance was made and, then, once
such Delinquency Advance has been reimbursed,  out of general collections on the
Mortgage Loans and REO Properties pursuant to Section 3.05(a).

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

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

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


                                      122
<PAGE>


of Principal Balance Certificates  outstanding after the subsequent  adjustments
made on such Distribution Date under Section 4.04(c) below.

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

                                THE CERTIFICATES

     SECTION 5.01 The Certificates.

     (a) The Certificates  will be substantially in the respective forms annexed
hereto as Exhibits A-1 through A-15.  (In the case of the Class K  Certificates,
with the inclusion or exclusion of appropriate bracketed provisions contained in
Exhibit A-12 to reflect the applicable  subclass  designation.) The Certificates
will be issuable in registered form only; provided,  however, that in accordance
with Section 5.03 beneficial ownership interests in the Registered  Certificates
shall initially be held and transferred through the book-entry facilities of the
Depository.  The  Non-Registered  Certificates  will  be  issued  as  Definitive
Certificates.   The  REMIC  III  Regular   Certificates   will  be  issuable  in
denominations   corresponding  to  initial  Certificate  Principal  Balances  or
Certificate  Notional Amounts, as the case may be, as of the Closing Date of not
less than  $25,000  in the case of the Class A-1,  Class A-2,  Class B, Class C,
Class D and  Class E,  $100,000  in the case of the Class F,  Class G,  Class H,
Class J and Class K, and $1,000,000 in the case of the Class X Certificates, and
in each such case in any whole dollar denomination in excess thereof;  provided,
however,  that a single  Certificate  of each Class  thereof  may be issued in a
different  denomination.  The  Residual  Certificates  will be issuable  only in
denominations  representing  Percentage  Interests  of not less  than 20% in the
related Class.

     (b) The Certificates shall be executed by manual or facsimile  signature on
behalf of the Trustee in its  capacity  as trustee  hereunder  by an  authorized
officer.  Certificates bearing the manual or facsimile signatures of individuals
who were at any time the authorized officers of the Trustee shall be entitled to
all benefits under this Agreement, subject to the following


                                      123
<PAGE>


sentence,  notwithstanding  that such  individuals or any of them have ceased to
hold such offices prior to the  authentication and delivery of such Certificates
or did not hold such offices at the date of such  Certificates.  No  Certificate
shall be  entitled  to any  benefit  under this  Agreement,  or be valid for any
purpose,  however,  unless there appears on such  Certificate  a certificate  of
authentication  substantially  in the form  provided for herein  executed by the
Certificate   Registrar   by  manual   signature,   and  such   certificate   of
authentication upon any Certificate shall be conclusive  evidence,  and the only
evidence,  that such  Certificate  has been  duly  authenticated  and  delivered
hereunder. All Certificates shall be dated the date of their authentication.

     SECTION 5.02 Registration of Transfer and Exchange of Certificates.

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

     (b) (i)No transfer of any  Non-Registered  Certificate shall be made unless
such transfer is made pursuant to an effective  registration statement under the
Securities Act, and effective  registration or  qualification  under  applicable
state  securities  laws, or is made in a transaction  that does not require such
registration  or  qualification.  If  such  a  transfer  is to be  made  without
registration under the Securities Act, other than a transfer by the Depositor or
an  Affiliate  thereof,  then the  Trustee  shall  require,  in order to  assure
compliance with such laws, receipt by it and the Depositor of:

     (A) if such transfer is  purportedly  being made in reliance upon Rule 144A
     under the Securities Act, a certificate from the Certificateholder desiring
     to effect such transfer  substantially  in the form attached as Exhibit B-1
     hereto  and  a  certificate  from  such   Certificateholder's   prospective
     transferee substantially in the form attached as Exhibit B-2 hereto; and

     (B) in all  other  cases,  (1) a  certificate  from  the  Certificateholder
     desiring to effect such transfer  substantially in the form attached hereto
     as Exhibit B-1 and a certificate from such Certificateholder's  prospective
     transferee  substantially  in the form attached  hereto as Exhibit B-3, and
     (2)  unless  the  Depositor  directs  otherwise,   an  Opinion  of  Counsel
     satisfactory  to the  Trustee  and the  Depositor  to the effect  that such
     transfer may


                                      124
<PAGE>


     be made without such registration (which Opinion of Counsel shall not be an
     expense of the Trust Fund or of the  Depositor,  the Master  Servicer,  the
     Special  Servicer,  the  Trustee  or the  Certificate  Registrar  in  their
     respective capacities as such).

     (ii) None of the  Depositor,  the Trustee or the  Certificate  Registrar is
obligated to register or qualify any Class of Non-Registered  Certificates under
the  Securities  Act or any  other  securities  law or to take  any  action  not
otherwise   required  under  this  Agreement  to  permit  the  transfer  of  any
Non-Registered Certificate without registration or qualification.  Any Holder of
a Non-Registered  Certificate desiring to effect such a transfer shall, and does
hereby  agree to,  indemnify  the  Depositor,  the Trustee  and the  Certificate
Registrar against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

     (c) (i) No transfer of a Senior  Certificate or any interest  therein shall
be made  (A) to any  employee  benefit  plan or  other  retirement  arrangement,
including  individual  retirement  accounts  and  annuities,   Keogh  plans  and
collective  investment funds and separate accounts in which such plans, accounts
or  arrangements  are invested,  that is subject to ERISA or Section 4975 of the
Code  (each,  a  "Plan"),  or (B) to any Person who is  directly  or  indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as  trustee  of, or with  "plan  assets"  of a Plan,  unless:  (1) such Plan
qualifies  for the  exemptive  relief  available  under the terms of  Prohibited
Transaction  Exemption 94-29 (granted to certain affiliates of the Depositor) or
Prohibited  Transaction  Exemption  89-88,  90-83  or  D-10433  granted  to  the
underwriters  of the  Certificates  and (2) at the  time of such  transfer,  the
Senior  Certificates  continue  to be  rated  in  one of the  top  three  rating
categories by at least one Rating Agency.

     (ii) No transfer of a Non-Registered  Certificate  shall be made (A) to any
Plan  or  (B) to any  Person  who is  directly  or  indirectly  purchasing  such
Certificate or interest  therein on behalf of, as named fiduciary of, as trustee
of, or with "plan assets" of a Plan, unless the prospective  transferee provides
the  Depositor,  the Trustee and the Master  Servicer with an opinion of counsel
satisfactory  to the  Depositor,  the Trustee and the Master  Servicer that such
transfer is permissible  under  applicable law, will not constitute or result in
any non-exempt  prohibited  transaction  under ERISA or Section 4975 of the Code
and will not subject the  Depositor,  the Trustee or the Master  Servicer to any
obligation in addition to those  undertaken  herein.  In lieu of such opinion of
counsel, the prospective transferee of a Non-Registered  Certificate that is not
a Residual Certificate may provide a certification of facts substantially to the
effect that the purchase of such  Certificate  by or on behalf of, or with "plan
assets" of, any Plan is permissible under applicable law, will not constitute or
result in any non-exempt  prohibited  transaction under ERISA or Section 4975 of
the Code, will not subject the Depositor,  the Trustee or the Master Servicer to
any  obligation  in  addition  to those  undertaken  herein,  and the  following
conditions are met: (a) the source of funds used to purchase such Certificate is
an "insurance company general account" (as such term is defined in United States
Department of Labor Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60"))
and (b) the  conditions  set forth in Sections I and III of PTCE 95-60 have been
satisfied  as of the  date  of the  acquisition  of  such  Certificates  and the
condition  set forth in Section I(a) of PTCE 95-60 will be satisfied  throughout
the  prospective  transferees'  holding of such  Certificates.  Any purchaser of
Book-Entry Certificates will be deemed to have represented by such purchase that
either (a) such purchaser is not a Plan and is not purchasing such  Certificates
by or on behalf of, or with "plan


                                      125
<PAGE>


assets" of, any Plan or (b) the purchase of any such Certificate by or on behalf
of, or with "plan assets" of, any Plan is permissible under applicable law, will
not result in any non-exempt prohibited  transaction under ERISA or Section 4975
of the Code,  and will not  subject  the  Depositor,  the  Trustee or the Master
Servicer  to any  obligation  in addition to those  undertaken  herein,  and the
following  conditions  are met:  (a) the source of funds used to  purchase  such
Certificate is an "insurance  company general  account" (as such term is defined
in PTCE  95-60) and (b) the  conditions  set forth in Sections I and III of PTCE
95-60 have been satisfied as of the date of the acquisition of such Certificates
and the  condition  set forth in Section  I(a) of PTCE  95-60 will be  satisfied
throughout  the  prospective  transferees'  holding  of such  Certificates.  The
Trustee  may  require  that  any   prospective   transferee  of  a  Subordinated
Certificate that is held as a Definitive Certificate provide such certifications
as the Trustee may deem  desirable or necessary in order to establish  that such
transferee or the Person in whose name such  registration  is requested is not a
Plan or a Person who is directly or indirectly  purchasing  such  Certificate on
behalf  of, as named  fiduciary  of, as trustee  of, or with "plan  assets" of a
Plan. The Trustee shall not have any  responsibility  to monitor or restrict the
transfer of Ownership  Interests in any  Certificates  that are in the form of a
Book-Entry Certificate.

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

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

          (B) In connection with any proposed Transfer of any Ownership Interest
     in a Residual Certificate, the Trustee shall require delivery to it, and no
     Transfer of any Residual  Certificate shall be registered until the Trustee
     receives,  an affidavit  and agreement  substantially  in the form attached
     hereto as Exhibit  C-1 (a  "Transfer  Affidavit  and  Agreement")  from the
     proposed  Transferee,  in form and substance  satisfactory  to the Trustee,
     representing and warranting,  among other things, that such Transferee is a
     Permitted  Transferee,  that it is not acquiring its Ownership  Interest in
     the Residual  Certificate that is the subject of the proposed Transfer as a
     nominee,  trustee  or  agent  for  any  Person  that  is  not  a  Permitted
     Transferee,  that for so long as it retains  its  Ownership  Interest  in a
     Residual  Certificate,  it will endeavor to remain a Permitted  Transferee,
     that it is a United States Person,  and that it has reviewed the provisions
     of this Section 5.02(d) and agrees to be bound by them.

          (C) Notwithstanding the delivery of a Transfer Affidavit and Agreement
     by a proposed Transferee under clause (B) above, if the Trustee has actual


                                      126
<PAGE>


     knowledge that the proposed Transferee is not a Permitted  Transferee or is
     not a United  States  Person,  no  Transfer of an  Ownership  Interest in a
     Residual Certificate to such proposed Transferee shall be effected.

          (D) Each  Person  holding or  acquiring  any  Ownership  Interest in a
     Residual  Certificate  shall agree (1) to require a Transfer  Affidavit and
     Agreement from any  prospective  Transferee to whom such Person attempts to
     transfer its Ownership Interest in such Residual Certificate and (2) not to
     transfer its  Ownership  Interest in such  Residual  Certificate  unless it
     provides to the Trustee a  certificate  substantially  in the form attached
     hereto as Exhibit C-2 stating that,  among other  things,  it has no actual
     knowledge that such prospective Transferee is not a Permitted Transferee or
     is not a United States Person.

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

     (ii) (A) If any  purported  Transferee  shall become a Holder of a Residual
Certificate  in violation of the  provisions  of this Section  5.02(d) or if any
Holder of a Residual Certificate shall lose its status as a Permitted Transferee
or a United  States  Person,  then the last  preceding  Holder of such  Residual
Certificate  that was in compliance  with the provisions of this Section 5.02(d)
shall be  restored,  to the  extent  permitted  by law,  to all rights as Holder
thereof  retroactive  to the  date  of  registration  of such  Transfer  of such
Residual  Certificate.  None of the Trustee,  the Master  Servicer,  the Special
Servicer or the Certificate Registrar shall be under any liability to any Person
for any  registration of Transfer of a Residual  Certificate that is in fact not
permitted  by this  Section  5.02(d)  or for  making  any  payments  due on such
Certificate to the Holder thereof or for taking any other action with respect to
such Holder under the provisions of this Agreement.

          (B) If any  purported  Transferee  shall become a Holder of a Residual
     Certificate in violation of the restrictions in this Section 5.02(d), or if
     any Holder of a Residual  Certificate  shall lose its status as a Permitted
     Transferee  or  a  United  States  Person,  and  to  the  extent  that  the
     retroactive  restoration of the rights of the prior Holder of such Residual
     Certificate as described in clause (ii)(A) above shall be invalid,  illegal
     or unenforceable,  then the Trustee shall have the right, without notice to
     the Holder or any prior Holder of such Residual  Certificate,  to sell such
     Residual  Certificate to a purchaser  selected by the Trustee on such terms
     as the Trustee may choose. Such non-complying Holder shall promptly endorse
     and deliver such Residual  Certificate in accordance with the  instructions
     of the Trustee.  Such  purchaser may be the Trustee itself or any Affiliate
     of the Trustee.  The proceeds of such sale, net of the  commissions  (which
     may include commissions payable to the Trustee or its Affiliates), expenses
     and  taxes  due,  if  any,   will  be  remitted  by  the  Trustee  to  such
     non-complying Holder. The terms


                                      127
<PAGE>


     and conditions of any sale under this clause (ii)(B) shall be determined in
     the sole discretion of the Trustee,  and the Trustee shall not be liable to
     any Person  having an  Ownership  Interest in a Residual  Certificate  as a
     result of its exercise of such discretion.

     (iii) The Trustee shall make available to the Internal  Revenue Service and
those Persons  specified by the REMIC Provisions,  all information  necessary to
compute any tax imposed (A) as a result of the Transfer of an Ownership Interest
in a  Residual  Certificate  to any Person  who is not a  Permitted  Transferee,
including   the   information   described  in  Treasury   Regulations   Sections
1.860D-1(b)(5) and 1.860E-2(a)(5)with respect to the "excess inclusions" of such
Residual  Certificate and (B) as a result of any regulated  investment  company,
real estate investment trust, common trust fund,  partnership,  trust, estate or
organization  described  in  Section  1381 of the Code that  holds an  Ownership
Interest  in a Residual  Certificate  having as among its record  holders at any
time any Person  which is not a Permitted  Transferee.  The Person  holding such
Ownership  Interest shall be responsible for the reasonable  compensation of the
Trustee for providing such information.

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

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

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

     (e) Subject to the preceding  subsections,  upon surrender for registration
of  transfer of any  Certificate  at the  offices of the  Certificate  Registrar
maintained  for such  purpose,  the Trustee  shall  execute and the  Certificate
Registrar  shall  authenticate  and  deliver,  in the  name  of  the  designated
transferee or transferees,  one or more new  Certificates of the same Class of a
like aggregate Percentage Interest.

     (f) At the option of any Holder,  its  Certificates  may be  exchanged  for
other  Certificates  of  authorized  denominations  of the same  Class of a like
aggregate  Percentage  Interest,  upon  surrender  of  the  Certificates  to  be
exchanged  at the  offices  of the  Certificate  Registrar  maintained  for such
purpose. Whenever any Certificates are so surrendered for


                                      128
<PAGE>


exchange,  the  Trustee  shall  execute  and  the  Certificate  Registrar  shall
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive.

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

     (h) No service  charge  shall be imposed  for any  transfer  or exchange of
Certificates,  but the Trustee or the Certificate  Registrar may require payment
of a sum  sufficient to cover any tax or other  governmental  charge that may be
imposed in connection with any transfer or exchange of Certificates.

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

     (j) Upon  request,  the  Certificate  Registrar  shall  provide  the Master
Servicer,  the Special  Servicer and the  Depositor  with an updated copy of the
Certificate  Register on or about January 1 and July 1 of each year,  commencing
July 1, 1999.

     SECTION 5.03 Book-Entry Certificates.

     (a) Each Class of Registered  Certificates shall initially be issued as one
or more  Certificates  registered  in the name of the  Depository or its nominee
and, except as provided in subsection (c) below,  transfer of such  Certificates
may not be registered by the Certificate  Registrar unless such transfer is to a
successor  Depository that agrees to hold such  Certificates  for the respective
Certificate  Owners with Ownership  Interests  therein.  Such Certificate Owners
shall hold and  transfer  their  respective  Ownership  Interests in and to such
Certificates through the book-entry  facilities of the Depository and, except as
provided in subsection  (c) below,  shall not be entitled to  definitive,  fully
registered Certificates ("Definitive Certificates") in respect of such Ownership
Interests.  The Trustee shall not have any responsibility to monitor or restrict
the transfer of Ownership Interests in any Book-Entry Certificate. All transfers
by Certificate Owners of their respective  Ownership Interests in the Book-Entry
Certificates shall be made in accordance with the procedures  established by the
Depository  Participant or brokerage firm representing  such Certificate  Owner.
Each Depository  Participant shall only transfer the Ownership  Interests in the
Book-Entry  Certificates  of  Certificate  Owners it  represents or of brokerage
firms  for which it acts as agent in  accordance  with the  Depository's  normal
procedures.

     (b) The Trustee, the Master Servicer,  the Special Servicer,  the Depositor
and the  Certificate  Registrar  may for all  purposes,  including the making of
payments due on the  Book-Entry  Certificates,  deal with the  Depository as the
authorized  representative  of the  Certificate  Owners  with  respect  to  such
Certificates  for the purposes of  exercising  the rights of  Certificateholders
hereunder.  The rights of  Certificate  Owners  with  respect to the  Book-Entry
Certificates shall be limited to those established by law and agreements between
such  Certificate  Owners and the Depository  Participants  and brokerage  firms
representing such Certificate


                                       129
<PAGE>


Owners.  Multiple  requests and directions from, and votes of, the Depository as
Holder of the  Book-Entry  Certificates  with respect to any  particular  matter
shall not be deemed  inconsistent  if they are made with  respect  to  different
Certificate  Owners.  The Trustee  may  establish  a  reasonable  record date in
connection with  solicitations of consents from or voting by  Certificateholders
and shall give notice to the Depository of such record date.

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


     SECTION 5.04 Mutilated, Destroyed, Lost or Stolen Certificates.

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

provided in the  definition of  "Certificateholder",  and none of the Depositor,
the  Master  Servicer,  the  Special  Servicer,  the  Trustee,  the  Certificate
Registrar  or any  agent  of any of them  shall be  affected  by  notice  to the
contrary except as provided in Section 5.02(d).

                                   ARTICLE VI

           THE DEPOSITOR, THE MASTER SERVICER AND THE SPECIAL SERVICER

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

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

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

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

     (b) The  Depositor,  the Master  Servicer  and the Special  Servicer may be
merged or consolidated with or into any Person, or transfer all or substantially
all of its assets to any  Person,  in which case any Person  resulting  from any
merger or  consolidation  to which the  Depositor,  the Master  Servicer  or the
Special  Servicer shall be a party, or any Person  succeeding to the business of
the  Depositor,  the Master  Servicer  and the  Special  Servicer,  shall be the
successor of the Depositor, the Master Servicer and the Special Servicer, as the
case may be,  hereunder,  without  the  execution  or filing of any paper or any
further act on the part of any of the  parties  hereto,  anything  herein to the
contrary notwithstanding;  provided that (i) such Person is qualified to service
multifamily  mortgage  loans on behalf  of FNMA or FHLMC  and (ii) such  merger,
consolidation  or succession will not result in the downgrade,  qualification or
withdrawal of the then-current  ratings of the Classes of Certificates that have
been so rated (as evidenced by a letter to such effect from each Rating Agency).

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

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

     None of the Depositor,  the Master Servicer, the Special Servicer or any of
the  directors,  officers,  employees  or agents of the  Depositor,  the  Master
Servicer or the Special  Servicer shall be under any liability to the Trust Fund
or the Certificateholders for any action taken or for refraining from the taking
of any  action  in good  faith  pursuant  to this  Agreement  or for  errors  in
judgment;   provided,  however,  that  this  provision  shall  not  protect  the
Depositor,  the Master Servicer, the Special Servicer or any such Person against
any breach of warranties or  representations  made herein or any liability which
would  otherwise  be  imposed  by reason of  willful  misfeasance,  bad faith or
negligence in the  performance  of duties or by reason of reckless  disregard of
obligations  and duties  hereunder.  The  Depositor,  the Master  Servicer,  the
Special Servicer and any director,  officer, employee or agent of the Depositor,
the  Master  Servicer  or the  Special  Servicer  may rely in good  faith on any
document of any kind prima facie  properly  executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Master Servicer and
the  Special  Servicer  and any  director,  officer,  employee  or  agent of the
Depositor,  the Master Servicer or the Special  Servicer shall be indemnified by
the Trust Fund and held harmless against any loss, liability or expense incurred
in  connection  with  any  legal  action  relating  to  this  Agreement  or  the
Certificates or any asset of the Trust Fund,  other than any loss,  liability or
expense  specifically  required to be borne by such Person pursuant to the terms
hereof, or which constitutes a Servicing Advance (and is otherwise  specifically
reimbursable  hereunder),  or which is incurred by such Person by reason of such
Person's willful misfeasance, bad faith or negligence in the performance of such
Person's duties  hereunder or by reason of such Person's  reckless  disregard of
obligations and duties hereunder.


                                      132
<PAGE>


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

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

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

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

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

                                  ARTICLE VII

Servicer,  as applicable,  is diligently  pursuing such cure, such 30 day period
shall be extended for an additional 30 days; or

     (v) any breach on the part of the Master  Servicer or the Special  Servicer
of any  representation or warranty  contained in this Agreement which materially
and adversely affects the interests of any Class of Certificateholders and which

of  Certificates  entitled to not less than 25% of the Voting Rights;  provided,
however,  if such  breach is capable of being  cured and the Master  Servicer or
Special  Servicer,  as  applicable,  such 30 day period shall be extended for an
additional 30 days; or

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

     (ix) the Trustee  shall have received  written  notice from FITCH IBCA that

would result in the  downgrade,  qualification  or withdrawal of any rating then
assigned by such Rating Agency to any Class of Certificates, or

     (x) the Master Servicer or the Special  Servicer is removed from Standard &
Poor's approved  master servicer list or special  servicer list, as the case may
be,  and the  ratings  of any of the  Certificates  by  Standard  &  Poor's  are
downgraded,  qualified or withdrawn  (including,  without limitation,  placed on
"negative credit watch") in connection with such removal.

     (b) If any Event of Default  with  respect to the  Master  Servicer  or the
Special  Servicer  (in either case for  purposes of this  Section  7.01(b),  the
"Defaulting  Party") shall occur and be continuing,  then, and in each and every
such case,  so long as such Event of Default shall not have been  remedied,  the
Depositor  or the Trustee  may,  and at the written  direction of the Holders of
Certificates  entitled to at least 51% of the Voting  Rights,  the Trustee shall
terminate,  by notice in writing to the  Defaulting  Party,  with a copy of such
notice to the  Depositor (if the  termination  is effected by the Trustee) or to
the Trustee (if the termination is effected by the Depositor), all of the rights
and  obligations of the Defaulting  Party under this Agreement and in and to the
Mortgage Loans and the proceeds thereof (other than any rights of the Defaulting
Party as Certificateholder).  From and after the receipt by the Defaulting Party
of such written  notice,  all authority and power of the Defaulting  Party under
this Agreement, whether with respect to the Certificates (other than as a Holder
of any  Certificate)  or the Mortgage  Loans or otherwise,  shall pass to and be
vested  in the  Trustee  pursuant  to  and  under  this  Section,  and,  without
limitation,  the  Trustee is hereby  authorized  and  empowered  to execute  and
deliver,  on  behalf  of  and  at  the  expense  of  the  Defaulting  Party,  as
attorney-in-fact or otherwise, any and all documents and other instruments,  and
to do or accomplish all other acts or things  necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement  or  assignment  of the  Mortgage  Loans and related  documents,  or
otherwise.  The Master Servicer and the Special  Servicer each agrees that if it
is terminated  pursuant to this Section  7.01(b),  it shall promptly (and in any
event no later than ten Business Days subsequent to its receipt of the notice of
termination)  provide  the  Trustee or any other  Successor  Master  Servicer or
Special Servicer with all documents and records  requested by it to enable it to
assume  the  Master  Servicer's  or  Special  Servicer's,  as the  case  may be,
functions hereunder, and shall


                                      135
<PAGE>


cooperate  with the Trustee or any other  Successor  Master  Servicer or Special
Servicer  in  effecting  the  termination  of the Master  Servicer's  or Special
Servicer's,   as  the  case  may  be,  responsibilities  and  rights  hereunder,
including,  without  limitation,  the transfer  within two Business  Days to the
Trustee  or  any  other  Successor  Master  Servicer  or  Special  Servicer  for
administration  by it of all cash  amounts  which shall at the time be or should
have been  credited  by the  Master  Servicer  or the  Special  Servicer  to the
Certificate Account, the Distribution  Account, the REO Account or any Servicing
Account or thereafter be received with respect to the Mortgage  Loans or any REO
Property (provided,  however,  that the Master Servicer and the Special Servicer
each shall continue to be entitled to receive all amounts accrued or owing to it
under this  Agreement  on or prior to the date of such  termination,  whether in
respect of Advances made by it or otherwise, and it and its directors, officers,
employees  and agents  shall  continue to be entitled to the benefits of Section
6.03 notwithstanding any such termination).

     SECTION 7.02 Trustee to Act; Appointment of Successor.

     On and after the time the Master Servicer or the Special  Servicer  resigns
pursuant to Section 6.04 or receives a notice of termination pursuant to Section
7.01, the Trustee shall be the successor in all respects to the Master  Servicer
or the Special Servicer,  as the case may be, in its capacity as such under this
Agreement  and the  transactions  set forth or provided  for herein and shall be
subject to all the responsibilities, duties and liabilities relating thereto and
arising thereafter placed on the Master Servicer or the Special Servicer, as the
case may be, by the terms and provisions hereof, including,  without limitation,
the Master Servicer's obligation to make Delinquency Advances; provided that any
failure  to  perform  such  duties  or  responsibilities  caused  by the  Master
Servicer's or the Special  Servicer's  failure to provide  information or monies
required  by Section  7.01  shall not be  considered  a default  by the  Trustee
hereunder.  The Trustee shall not be liable for any of the  representations  and
warranties  of the Master  Servicer  or the  Special  Servicer or for any losses
incurred by the Master Servicer or the Special Servicer pursuant to Section 3.06
hereunder  nor shall the  Trustee be  required to  purchase  any  Mortgage  Loan
hereunder.  As  compensation  therefor,  the  Trustee  shall be  entitled to the
applicable Master Servicing Fee and Special Servicing Fee and all funds relating
to the Mortgage  Loans which the Master  Servicer or the Special  Servicer would
have been  entitled  to charge to the  Certificate  Account or the  Distribution
Account if the Master  Servicer or the Special  Servicer  had  continued  to act
hereunder.  Notwithstanding the above, the Trustee may, if it shall be unwilling
to so act, or shall, if it is unable to so act or if the Holders of Certificates
entitled  to at least 51% of the  Voting  Rights so  request  in  writing to the
Trustee  or if the  Trustee  is not  approved  as a master  servicer  or special
servicer,  as the case may be, by each Rating Agency,  promptly appoint any FNMA
or  FHLMC-approved  mortgage loan servicing  institution that has a net worth of
not less than $10,000,000 and is otherwise  acceptable to each Rating Agency (as
evidenced by written  confirmation  therefrom to the effect that the appointment
of  such  institution  would  not  result  in the  downgrade,  qualification  or
withdrawal  of its rating then  assigned to any Class of  Certificates),  as the
successor to the Master Servicer hereunder or the Special Servicer,  as the case
may be, in the assumption of all or any part of the responsibilities,  duties or
liabilities of the Master Servicer or the Special Servicer,  as the case may be,
hereunder.  No appointment of a successor to the Master  Servicer or the Special
Servicer,  as the case may be, hereunder shall be effective until the assumption
of the successor to the Master Servicer or the Special Servicer, as the case may
be, of all the  responsibilities,  duties and liabilities of the Master Servicer
or the Special Servicer, as the case may be, hereunder. Pending appointment of a
successor to the


                                      136
<PAGE>


Master  Servicer or the Special  Servicer,  as the case may be,  hereunder,  the
Trustee shall act in such capacity as hereinabove  provided.  In connection with
any such appointment and assumption  described herein, the Trustee may make such
arrangements  for the compensation of such successor out of payments on Mortgage
Loans or otherwise as it and such successor shall agree; provided, however, that
no such  compensation  shall be in excess of that  permitted  the  resigning  or
terminated party hereunder.  The Depositor, the Trustee and such successor shall
take such  action,  consistent  with this  Agreement,  as shall be  necessary to
effectuate any such succession.

     SECTION 7.03 Notification to Certificateholders.

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

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

     SECTION 7.04 Waiver of Events of Default.

     The  Holders of  Certificates  representing  at least 66 2/3% of the Voting
Rights allocated to the Classes of Certificates affected by any Event of Default
hereunder may waive such Event of Default;  provided,  however, that an Event of
Default  under  clause (i) or (ii) of Section  7.01 may be waived only by all of
the Certificateholders of the affected Classes. Upon any such waiver of an Event
of  Default,  such Event of Default  shall cease to exist and shall be deemed to
have been remedied for every purpose  hereunder.  No such waiver shall extend to
any subsequent or other Event of Default or impair any right consequent  thereon
except to the extent expressly so waived.  Notwithstanding  any other provisions
of this Agreement, for purposes of waiving any Event of Default pursuant to this
Section  7.04,  Certificates  registered  in the  name of the  Depositor  or any
Affiliate  of the  Depositor  shall be entitled  to the same Voting  Rights with
respect to the matters  described  above as they would if any other  Person held
such Certificates.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

     SECTION 8.01 Duties of Trustee.

     (a) The Trustee,  prior to the  occurrence of an Event of Default and after
the  curing  or  waiver  of all  Events  of  Default  which  may have  occurred,
undertakes to perform such duties and only such duties as are  specifically  set
forth in this  Agreement.  If an Event of Default occurs and is continuing,  the
Trustee  (other than as successor  Master  Servicer or Special  Servicer)  shall
exercise such of the rights and powers vested in it by this  Agreement,  and use
the


                                      137
<PAGE>


same degree of care and skill in their  exercise as a prudent man would exercise
or use under the circumstances in the conduct of his own affairs. Any permissive
right of the Trustee  contained  in this  Agreement  shall not be construed as a
duty.

     (b) The Trustee, upon receipt of all resolutions, certificates, statements,
opinions,  reports,  documents,  orders or other  instruments  furnished  to the
Trustee  which  are  specifically  required  to be  furnished  pursuant  to  any
provision of this Agreement  (other than the Mortgage Files, the review of which
is  specifically  governed by the terms of Article  II),  shall  examine them to
determine  whether they conform to the  requirements of this  Agreement.  If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take such action as it deems appropriate to
have the  instrument  corrected.  The Trustee shall not be  responsible  for the
accuracy or content of any resolution,  certificate, statement, opinion, report,
document,  order or other  instrument  furnished  by the  Depositor,  the Master
Servicer or the Special Servicer or any other person and accepted by the Trustee
in good faith, pursuant to this Agreement.

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

     (i) Prior to the occurrence of an Event of Default, and after the curing of
all such Events of Default which may have occurred,  the duties and  obligations
of the Trustee  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 certificates or opinions furnished to
the Trustee and conforming to the requirements of this Agreement;

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

     (iii) The Trustee shall not be personally liable with respect to any action
taken,  suffered or omitted to be taken by it in good faith in  accordance  with
the direction of Holders of Certificates  entitled to at least 25% of the Voting
Rights  relating to the time,  method and place of conducting any proceeding for
any remedy available to the Trustee,  or exercising any trust or power conferred
upon the Trustee, under this Agreement.

     SECTION 8.02 Certain Matters Affecting the Trustee.

     Except as otherwise provided in Section 8.01:

     (i) The  Trustee  may  rely  upon and  shall  be  protected  in  acting  or
refraining from acting upon any resolution,  Officer's Certificate,  certificate
of auditors or any other certificate,  statement,  instrument,  opinion, report,
notice, request, consent, order, appraisal, bond


                                      138
<PAGE>


or other paper or document  reasonably  believed by it to be genuine and to have
been signed or presented by the proper party or parties;

     (ii) The Trustee may consult  with  counsel and the written  advice of such
counsel or 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  therewith and the expense of such  consultation
with counsel shall be reimbursable under Section 8.05(b) hereof;

     (iii) The Trustee shall not be under any  obligation to exercise any of the
trusts or powers vested in it by this Agreement or to make any  investigation of
matters  arising  hereunder or to  institute,  conduct or defend any  litigation
hereunder or in relation hereto at the request, order or direction of any of the
Certificateholders,  pursuant to the provisions of this  Agreement,  unless such
Certificateholders  shall have  offered to the  Trustee  reasonable  security or
indemnity  against the costs,  expenses  and  liabilities  which may be incurred
therein or thereby;  the Trustee shall not be required to expend or risk its own
funds or otherwise  incur any financial  liability in the  performance of any of
its duties  hereunder,  or in the exercise of any of its rights or powers, if it
shall have  reasonable  grounds for  believing  that  repayment of such funds or
adequate  indemnity against such risk or liability is not reasonably  assured to
it;  nothing  contained  herein  shall,  however,  relieve  the  Trustee  of the
obligation, upon the occurrence of an Event of Default which has not been cured,
to exercise such of the rights and powers vested in it by this Agreement, and to
use the same  degree of care and skill in their  exercise as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs;

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

     (v) Prior to the occurrence of an Event of Default  hereunder and after the
curing of all Events of Default which may have  occurred,  the Trustee shall not
be bound to make any  investigation  into the  facts or  matters  stated  in any
resolution,   certificate,   statement,  instrument,  opinion,  report,  notice,
request,  consent,  order,  approval,  bond or other paper or  document,  unless
requested  in writing to do so by Holders of  Certificates  entitled to at least
50% of the  Voting  Rights;  provided,  however,  that if the  payment  within a
reasonable time to the Trustee of the costs,  expenses or liabilities  likely to
be incurred by it in the making of such  investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this  Agreement,  the  Trustee  may  require  reasonable  indemnity
against such expense or liability as a condition to taking any such action;

     (vi) The  Trustee  may  execute  any of the trusts or powers  hereunder  or
perform any duties hereunder  either directly or by or through agents,  provided
that the Trustee shall not be relieved  from such duties,  and the Trustee shall
remain responsible for all acts and omissions of any such agent;

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


                                      139
<PAGE>


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

     (viii) The Trustee shall not be responsible  for any act or omission of the
Master Servicer or the Special  Servicer (unless the Trustee is acting as Master
Servicer or the Special Servicer, as the case may be) or of the Depositor or any
other person.

     SECTION 8.03   Trustee   not  Liable  for   Validity  or   Sufficiency   of
                    Certificates or Mortgage Loans.

     The  recitals  contained  herein  and in the  Certificates,  other than the
representations  and warranties of, and the other  statements  attributed to the
Trustee in Sections 2.02,  2.05,  2.07 and 8.13 and the signature of the Trustee
set forth on each outstanding  Certificate,  shall be taken as the statements of
the Depositor,  the Master Servicer or the Special Servicer, as the case may be,
and the Trustee assumes no responsibility for correctness.  The Trustee makes no
representations  as to the validity or sufficiency of this Agreement  (except to
the extent set forth in Section  8.13) or of any  Certificate  (other than as to
the  signature  of the Trustee set forth  thereon)  or of any  Mortgage  Loan or
related  document.  The  Trustee  shall  not  be  accountable  for  the  use  or
application by the Depositor of any of the  Certificates  issued to it or of the
proceeds of such  Certificates,  or for the use or application of any funds paid
to the Depositor in respect of the assignment of the Mortgage Loans to the Trust
Fund, or any funds deposited in or withdrawn from the Certificate Account or any
other  account  by or on behalf of the  Depositor,  the Master  Servicer  or the
Special  Servicer.  The Trustee  shall not be  responsible  for the  accuracy or
content of any resolution,  certificate,  statement,  opinion, report, document,

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

     SECTION 8.04 Trustee May Own Certificates.

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

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

     (a) Monthly, the Trustee shall be entitled to withdraw the Trustee Fee from
the Distribution  Account pursuant to Section 3.05(b) for all services  rendered
by it in the  execution  of the trusts  hereby  created and in the  exercise and
performance  of any of the powers and duties  hereunder  of the  Trustee.  On or
prior to the  Distribution  Date in each month, the Trustee shall be entitled to
withdraw and pay itself from amounts then on deposit in the Distribution Account
an amount equal to the then unpaid Trustee Fees.

     (b) The Trustee and any of its  directors,  officers,  employees  or agents
shall be  indemnified  and held  harmless  by the Trust  Fund (to the  extent of
amounts on deposit in the  Distribution  Account from time to time)  against any
loss, liability or expense (including, without limitation, costs and expenses of
litigation,  and of investigation,  counsel fees, damages, judgments and amounts
paid in settlement)  arising out of, or incurred in connection  with, any act or
omission of the Trustee  relating to the exercise and  performance of any of the
powers and duties of the Trustee  hereunder;  provided  that neither the Trustee
nor any of the other above


                                      140
<PAGE>


specified Persons shall be entitled to indemnification  pursuant to this Section
8.05(b) for (i) allocable overhead,  (ii) expenses or disbursements  incurred or
made by or on behalf  of the  Trustee  in the  normal  course  of the  Trustee's
performing its routine duties in accordance  with any of the provisions  hereof,
(iii)  any  expense  or  liability  specifically  required  to be borne  thereby
pursuant to the terms hereof, or (iv) any loss, liability or expense incurred by
reason of willful misfeasance, bad faith or negligence in the performance of the
Trustee's  obligations and duties hereunder,  or by reason of reckless disregard
of  such  obligations  or  duties,  or  as  may  arise  from  a  breach  of  any
representation,  warranty or covenant of the Trustee made herein. The provisions
of this Section  8.05(b) shall survive any resignation or removal of the Trustee
and appointment of a successor trustee.

     SECTION 8.06 Eligibility Requirements for Trustee.

     The Trustee hereunder shall at all times be an association or a corporation
organized and doing  business  under the laws of the United States of America or
any State  thereof or the  District of Columbia,  authorized  under such laws to
exercise  trust  powers,  having a  combined  capital  and  surplus  of at least
$100,000,000  and  subject to  supervision  or  examination  by federal or state
authority.  If such association or corporation publishes reports of condition at
least  annually,  pursuant  to  law  or to the  requirements  of  the  aforesaid
supervising  or examining  authority,  then for the purposes of this Section the
combined capital and surplus of such association or corporation  shall be deemed
to be its combined capital and surplus as set forth in its most recent report of
condition so published.  The long-term unsecured debt obligations of the Trustee
shall at all times be rated not less than "AA" by  Standard & Poor's and "AA" by
FITCH IBCA (or, if not rated by FITCH IBCA,  otherwise  acceptable to FITCH IBCA
as would not result in a  qualification,  downgrade or  withdrawal of the rating
assigned  by FITCH IBCA to any Class of  Certificates)  or such other  rating as
shall not result in the  qualification,  downgrade or  withdrawal  of any of the
ratings then assigned to the respective Classes of Certificates, as confirmed in
writing by each Rating Agency. In case at any time the Trustee 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;
provided that if the Trustee shall cease to be so eligible  because its combined
capital  and  surplus  is no  longer  at  least  $100,000,000  or its  long-term
unsecured debt rating no longer conforms to the  requirements of the immediately
preceding  sentence,  and if the Trustee proposes to the other parties hereto to
enter into an agreement with (and reasonably  acceptable to) each of them or the
Trustee  appoints  a fiscal  agent,  and if in light of such  agreement  or such
appointment,  the Trustee's  continuing  to act in such  capacity  would not (as
evidenced in writing by each rating  Agency) cause any Rating Agency to qualify,
downgrade or withdraw any rating assigned  thereby to any Class of Certificates,
then upon the execution and delivery of such agreement or the  effectiveness  of
such appointment,  the Trustee shall not be required to resign, and may continue
in such  capacity,  for so long as none of the  ratings  assigned  by the Rating
Agencies to the Certificates is adversely  affected thereby.  The corporation or
association  serving as Trustee may have normal banking and trust  relationships
with the  Depositor,  the  Master  Servicer,  the  Special  Servicer  and  their
respective Affiliates.

     SECTION 8.07 Resignation and Removal of the Trustee.

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

     (b) 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 the Master 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,  then the  Depositor may remove the Trustee and appoint a successor
trustee acceptable to the Master Servicer by written  instrument,  in duplicate,
which  instrument  shall be  delivered  to the  Trustee  so  removed  and to the
successor  trustee.  A copy of such instrument  shall be delivered to the Master
Servicer, the Special Servicer and the Certificateholders by the Depositor.

     (c) The  Holders  of  Certificates  entitled  to at least 51% of the Voting
Rights may at any time remove the  Trustee  and  appoint a successor  trustee by
written  instrument or  instruments,  in  triplicate,  signed by such Holders or
their  attorneys-in-fact duly authorized,  one complete set of which instruments
shall be  delivered to the Master  Servicer,  one complete set to the Trustee so
removed and one  complete  set to the  successor  so  appointed.  A copy of such
instrument  shall be delivered to the  Depositor,  the Special  Servicer and the
remaining Certificateholders by the Master Servicer.

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

     SECTION 8.08 Successor Trustee.

     (a) Any  successor  trustee  appointed  as provided  in Section  8.07 shall
execute,  acknowledge  and deliver to the Depositor,  the Master  Servicer,  the
Special  Servicer and to its  predecessor  trustee an instrument  accepting such
appointment  hereunder,   and  thereupon  the  resignation  or  removal  of  the
predecessor trustee shall become effective and such successor


                                      142
<PAGE>


trustee, without any further act, deed or conveyance,  shall become fully vested
with  all  the  rights,  powers,  duties  and  obligations  of  its  predecessor
hereunder,  with the like effect as if originally  named as trustee herein.  The
predecessor  trustee shall deliver to the successor  trustee all Mortgage  Files
and  related  documents  and  statements  held by it  hereunder  (other than any
Mortgage  Files at the time held on its behalf by a Custodian,  which  Custodian
shall become the agent of the successor trustee), and the Depositor,  the Master
Servicer,  the Special  Servicer and the  predecessor  trustee shall execute and
deliver such  instruments and do such other things as may reasonably be required
to more fully and certainly  vest and confirm in the successor  trustee all such
rights,  powers, duties and obligations,  and to enable the successor trustee to
perform its obligations hereunder.

     (b) 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.

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

     SECTION 8.09 Merger or Consolidation of Trustee.

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

     SECTION 8.10 Appointment of Co-Trustee or Separate Trustee.

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


                                      143
<PAGE>


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

     (c) Any notice,  request or other  writing  given to the  Trustee  shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as  effectively  as if given to each of them.  Every  instrument  appointing any
separate  trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee,  upon its acceptance
of the trusts conferred,  shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided  therein,  subject to all the  provisions of this  Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording  protection to, the Trustee.  Every
such instrument shall be filed with the Trustee.

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

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

     SECTION 8.11 Appointment of Custodians.

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


                                      144
<PAGE>


The appointment of one or more Custodians shall not relieve the Trustee from any
of its obligations  hereunder,  and the Trustee shall remain responsible for all
acts and omissions of any Custodian.

     SECTION 8.12 Access to Certain Information.

     (a) On or  prior  to the  date  of the  first  sale  of any  Non-Registered
Certificate to an Independent  third party,  the Depositor  shall provide to the
Trustee  ten copies of any  private  placement  memorandum  or other  disclosure
document used by the Depositor or its Affiliate in connection with the offer and
sale of the  Class of  Certificates  to which  such  Non-Registered  Certificate
belongs.  In addition,  if any such private  placement  memorandum or disclosure
document is revised,  amended or supplemented at any time following the delivery
thereof to the Trustee,  the Depositor promptly shall inform the Trustee of such
event and shall  deliver  to the  Trustee  ten copies of the  private  placement
memorandum or disclosure  document,  as revised,  amended or  supplemented.  The
Trustee shall maintain at its offices  primarily  responsible for  administering
the Trust Fund (or at the Primary  Servicing  Office of the Master Servicer) and

hours for review by any Holder, Certificate Owner or prospective transferee of a
Certificate or interest therein, originals or copies of the following items: (i)

Non-Registered Certificate or interest therein, any private placement memorandum
or other disclosure document relating to the Class of Certificates to which such

the conditions  set forth in clauses (i) and (ii) of the first sentence  thereof
was not  satisfied  (but  only  for so long as such  Mortgaged  Property  or the
related Mortgage Loan are part of the Trust Fund),  (H) the respective  Mortgage
Files,  including,  without limitation,  any and all modifications,  waivers and
amendments of the terms of a Mortgage  Loan entered into by the Master  Servicer

     In connection with providing  access to or copies of the items described in
the preceding paragraph,  the Trustee may require (a) in the case of Certificate

reasonably satisfactory to the Trustee, generally to the effect that such Person
is a beneficial holder of Certificates, is requesting the information solely for
use in  evaluating  such  Person's  investment  in  the  Certificates  and  will
otherwise  keep  such  information  confidential  and  (b)  in  the  case  of  a
prospective purchaser, a written confirmation executed by the requesting Person,

provisions of this Section 8.12(a), the Trustee shall have no responsibility for
the accuracy,  completeness or sufficiency for any purpose of any information so
made available or furnished by it pursuant to this Section 8.12(a).

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

     SECTION 8.13 Representations and Warranties of the Trustee.

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

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

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

     (iii) This Agreement, assuming due authorization, execution and delivery by
the Special  Servicer,  the Master  Servicer and the  Depositor,  constitutes  a
valid,  legal and binding  obligation  of the Trustee,  enforceable  against the
Trustee in accordance with the terms hereof,  subject to applicable  bankruptcy,
insolvency, reorganization,  moratorium and other laws affecting the enforcement
of creditor's rights generally, and general principles of equity,  regardless of
whether such enforcement is considered in a proceeding in equity or at law.

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

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

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

     SECTION 8.14 Filings with the Securities and Exchange Commission.

     Based  on  information  furnished  to it by the  Master  Servicer  and  the
Depositor  (in an 80 column  unformatted  electronic  format  acceptable  to the
Trustee),  the Trustee  will prepare and file with the  Securities  and Exchange
Commission on Form 8-K (including  EDGAR  filings),  on behalf of the Trust Fund
the Distribution  Date Statement.  The Trustee shall have no  responsibility  to
file any items other than those specified in this Section 8.14. Prior to January
2, 2000 (and each anniversary thereafter until directed by the Depositor to file
a Form 15, delisting the transaction) the Trustee shall hire counsel selected by
the  Depositor to file Form 10-K's on behalf of the Trust Fund for the preceding
fiscal  year.  Any fees and  expenses  accrued  and  incurred  by the Trustee in
connection with this Section 8.14 (including  reasonable  attorneys' fees) shall
be reimbursed  to it by the  Depositor.  Prior to filing any such  reports,  the
Trustee shall submit reports to the Depositor for review and approval.

                                   ARTICLE IX

                                   TERMINATION

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

     Subject to Section 9.02, the Trust Fund and the respective  obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Special  Servicer and the Trustee (other than the  obligations of the Trustee to
provide for and make  payments to  Certificateholders  as  hereafter  set forth)
shall   terminate   upon   payment   (or   provision   for   payment)   to   the
Certificateholders  of all  amounts  held by or on  behalf  of the  Trustee  and
required  hereunder to be so paid on the Distribution Date following the earlier
to occur of (i) the purchase


                                      147
<PAGE>


by the Master  Servicer  or the  Depositor  of all  Mortgage  Loans and each REO
Property  remaining in REMIC I at a price (to be determined as of the end of the
Collection Period for the anticipated Final  Distribution Date) equal to (A) the
aggregate Purchase Price of all the Mortgage Loans included in REMIC I, plus (B)
the  appraised  value of each REO  Property,  if any,  included in REMIC I (such
appraisal to be conducted by an Independent MAI-designated appraiser selected by
the Master  Servicer and approved by the Trustee),  minus (C) solely in the case
where the Master  Servicer is effecting such purchase,  the aggregate  amount of
unreimbursed Advances, together with any Advance Interest accrued and payable to
the Master  Servicer in respect of such Advances and any unpaid  Servicing Fees,
remaining  outstanding  (which  items  shall  be  deemed  to have  been  paid or
reimbursed to the Master Servicer in connection  with such  purchase),  and (ii)
the final payment or other  liquidation (or any advance with respect thereto) of
the last Mortgage Loan or REO Property remaining in REMIC I; provided,  however,
that in no event shall the trust created hereby  continue  beyond the expiration
of 21 years from the death of the last survivor of the  descendants of Joseph P.
Kennedy,  the late  ambassador  of the United  States to the Court of St. James,
living on the date hereof.

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


                                      148
<PAGE>


     Notice of any termination  shall be given promptly by the Trustee by letter
to Certificateholders  and, if not previously notified pursuant to the preceding
paragraph,  to the other  parties  hereto mailed (a) in the event such notice is
given in connection with the Master  Servicer's or the  Depositor's  purchase of
all of the  Mortgage  Loans  and each  REO  Property  remaining  in REMIC I, not
earlier  than the 15th day and not  later  than the 25th day of the  month  next
preceding  the  month  of the  final  distribution  on the  Certificates  or (b)
otherwise  during  the  month  of  such  final  distribution  on or  before  the
Determination  Date in such month, in each case specifying (i) the  Distribution
Date  upon  which  the  Trust  Fund will  terminate  and  final  payment  of the
Certificates  will be made,  (ii) the amount of any such final payment and (iii)
that the Record  Date  otherwise  applicable  to such  Distribution  Date is not
applicable,  payments  being made only upon  presentation  and  surrender of the
Certificates at the offices of the Certificate  Registrar or such other location
therein designated.

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

     SECTION 9.02 Additional Termination Requirements.

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

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

          (ii) during such 90-day liquidation period and at or prior to the time
     of making of the final payment on the Certificates,  the Trustee shall sell
     all of the assets of


                                      149
<PAGE>


     REMIC I to the Master Servicer or the Depositor,  as applicable,  for cash;
     and

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

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

                                   ARTICLE X

                           ADDITIONAL REMIC PROVISIONS

     SECTION 10.01 REMIC Administration.

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

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

     (c) The  Trustee,  as agent for the tax matters  person of each of REMIC I,
REMIC II and REMIC III,  shall (i) act on behalf of the REMIC in relation to any
tax matter or controversy  involving the Trust Fund and (ii) represent the Trust
Fund in any administrative or judicial  proceeding relating to an examination or
audit by any  governmental  taxing  authority  with respect  thereto.  The legal
expenses,  including  without  limitation  attorneys' or accountants'  fees, and
costs of any such  proceeding  and any liability  resulting  therefrom  shall be
expenses  of the Trust Fund and the Trustee  shall be entitled to  reimbursement
therefor  out of  amounts  attributable  to  the  Mortgage  Loans  and  any  REO
Properties on deposit in the Certificate Account


                                      150
<PAGE>


as provided by Section 3.05(a) unless such legal expenses and costs are incurred
by reason of the Trustee's willful misfeasance,  bad faith or negligence. In the
case of each of  REMIC  I,  REMIC II and  REMIC  III,  the  Holder  of  Residual
Certificates  representing the largest Percentage  Interest in the related Class
thereof shall be designated,  in the manner provided under Treasury  Regulations
Section 1.860F-4(d) and temporary Treasury Regulations Section 301.6231(a)(7)-1,
as the tax matters person of such REMIC. By its acceptance  thereof,  the Holder
of Residual  Certificates  representing the largest Percentage  Interest in each
Class thereof hereby agrees to  irrevocably  appoint the Trustee as its agent to
perform  all of the  duties of the tax  matters  person  for the  related  REMIC
created hereunder.

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

     (e)  The  Trustee  shall  provide  (i)  to  any  Transferor  of a  Residual
Certificate  such  information  as is necessary for the  application  of any tax
relating to the transfer of such Residual Certificate to any Person who is not a
Permitted Transferee, (ii) to the Certificateholders such information or reports
as are required by the Code or the REMIC Provisions  including  reports relating
to interest,  original issue discount and market  discount or premium (using the
Prepayment  Assumption)  and (iii) to the  Internal  Revenue  Service  the name,
title,  address  and  telephone  number  of the  person  who  will  serve as the
representative of each of REMIC I, REMIC II and REMIC III.

     (f) The Trustee  shall take such actions and shall cause each REMIC created
hereunder to take such actions as are  reasonably  within the Trustee's  control
and the scope of its  duties  more  specifically  set  forth  herein as shall be
necessary to maintain the status thereof as a REMIC under the REMIC  Provisions.
The Trustee shall not knowingly or intentionally take any action, cause REMIC I,
REMIC II or REMIC III to take any action or fail to take (or fail to cause to be
taken) any action  reasonably  within its  control  and the scope of duties more
specifically set forth herein, that, under the REMIC Provisions, if taken or not
taken,  as the case may be,  could (i)  adversely  affect the status of REMIC I,
REMIC  II or REMIC  III as a REMIC  or (ii)  result  (subject  to the  following
sentence)  in the  imposition  of a tax  upon  REMIC I,  REMIC  II or REMIC  III
(including but not limited to the tax on prohibited  transactions  as defined in
Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth
in Section  860G(d) of the Code) (either such event,  an "Adverse  REMIC Event")
unless the  Trustee  receives an Opinion of Counsel (at the expense of the party
seeking to take such action or, if such party fails to pay such expense, and the
Trustee  determines  that taking such action is in the best interest of REMIC I,
REMIC II or REMIC III and the  Certificateholders,  at the  expense of the Trust
Fund,  but in no event at the  expense of the  Trustee)  to the effect  that the
contemplated  action  will not,  with  respect  to any REMIC  created  hereunder
adversely affect such status or, unless the Master Servicer, the Trustee, or the
Special  Servicer,  as applicable  (or other Person  acceptable to the Trustee),
determine  that the monetary  exposure to REMIC I, REMIC II and REMIC III is not
material  and in its or  their  sole  discretion  to  indemnify,  to the  extent
reasonably  acceptable to the Trustee,  the Trust Fund against the imposition of
such tax.  Wherever  in this  Agreement a  contemplated  action may not be taken
because the timing of such action might result in the imposition of a tax on the
Trust Fund, or may only be taken pursuant to an Opinion of Counsel


                                      151
<PAGE>


that such  action  would not  impose a tax on the Trust  Fund,  such  action may
nonetheless be taken provided that the indemnity given in the preceding sentence
with respect to any taxes that might be imposed on the Trust Fund has been given
and  that all  other  preconditions  to the  taking  of such  action  have  been
satisfied. The Trustee shall not take or fail to take any action (whether or not
authorized  hereunder) as to which the Master Servicer has advised it in writing
that it has  received an Opinion of Counsel to the effect that an Adverse  REMIC
Event could occur with respect to such action. In addition,  prior to taking any
action with  respect to the Trust Fund or its assets,  or causing the Trust Fund
to take any action,  which is not  expressly  permitted  under the terms of this
Agreement,  each of the  parties  hereto  will  consult  with the Trustee or its
designee, in writing, with respect to whether such action could cause an Adverse
REMIC  Event to occur with  respect to REMIC I, REMIC II or REMIC III,  and such
party shall not take any such action, or cause REMIC I, REMIC II or REMIC III to
take any such action,  as to which the Trustee has advised it in writing that an
Adverse  REMIC Event could  occur.  The Trustee may consult with counsel to make
such written advice, and the cost of same shall be borne by the party seeking to
take the action not expressly  permitted by this Agreement.  At all times as may
be required by the Code,  the Trustee will to the extent  within its control and
the scope of its duties as specifically set forth herein, maintain substantially
all of the  assets of REMIC I as  "qualified  mortgages"  as  defined in Section
860G(a)(3)  of the  Code and  "permitted  investments"  as  defined  in  Section
860G(a)(5) of the Code.

     (g) In the event that any tax is imposed on  "prohibited  transactions"  of
REMIC I, REMIC II or REMIC III as defined in Section  860F(a)(2) of the Code, on
"net  income  from  foreclosure  property"  of REMIC I, REMIC II or REMIC III as
defined in  Section  860G(c) of the Code,  or on any  contributions  to REMIC I,
REMIC II or REMIC III after the Startup Day therefor pursuant to Section 860G(d)
of the  Code,  or any  other  tax is  imposed  by  the  Code  or any  applicable
provisions of state or local laws, such tax shall be charged (i) to the Trustee,
if such tax arises out of or results  from a breach by the Trustee of any of its
obligations  under this Agreement,  (ii) to any other party hereto,  if such tax
arises out of or results  from a breach by such party of any of its  obligations
under this Agreement, or (iii) otherwise (including,  without limitation, in the
case of any tax permitted to be incurred  pursuant to Section  3.17(a))  against
amounts on deposit in the Distribution Account as provided by Section 3.05(b).

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

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

     (j) None of the Master Servicer,  the Special Servicer or the Trustee shall
enter into any arrangement by which REMIC I, REMIC II or


                                      152
<PAGE>


REMIC III will  receive a fee or other  compensation  for  services  nor (to the
extent within its control)  permit REMIC I, REMIC II or REMIC III to receive any
income  from  assets  other  than  "qualified  mortgages"  as defined in Section
860G(a)(3)  of the  Code  or  "permitted  investments"  as  defined  in  Section
860G(a)(5) of the Code.

     (k) Within 30 days after the Closing  Date,  the Trustee  shall prepare and
file with the Internal Revenue Service Form 8811,  "Information  Return for Real
Estate Mortgage  Investment  Conduits (REMIC) and Issuers of Collateralized Debt
Obligations" for each of REMIC I, REMIC II and REMIC III.

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

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

     (a) The  Depositor  shall  provide or cause to be provided to the  Trustee,
within ten days after the Closing Date, all information or data that the Trustee
reasonably  determines to be relevant for tax purposes as to the  valuations and
issue prices of the  Certificates,  including,  without  limitation,  the price,
yield, prepayment assumption and projected cash flow of the Certificates.

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

     SECTION 10.03 Grantor Trust Administration.

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

     (b) The  Trustee  shall pay out of its own funds  any and all  routine  tax
administration  expenses of the Trust Fund  incurred with respect to the Grantor
Trust (but not including any professional  fees or expenses related to audits or
any  administrative or judicial  proceedings with respect to the Trust Fund that
involve the Internal Revenue Service or state tax


                                      153

authorities which extraordinary expenses shall be payable or reimbursable to the
Trustee  from the Trust Fund unless  otherwise  provided in Section  10.02(e) or
10.02(f)).

     (c) The  Trustee  shall  prepare,  sign  and  file  when due all of the Tax
Returns in respect of the Grantor  Trust.  The expenses of preparing  and filing
such returns  shall be borne by the Trustee  without any right of  reimbursement
therefor.  The other  parties  hereto  shall  provide  on a timely  basis to the
Trustee or its designee such information with respect to the Grantor Trust as is
in its  possession  and  reasonably  requested  by the  Trustee  to enable it to
perform  its  obligations  under  this  Section  10.02.   Without  limiting  the
generality  of the  foregoing,  the  Depositor,  within ten days  following  the
Trustee's  request  therefor,  shall  provide  in writing  to the  Trustee  such
information as is reasonably requested by the Trustee for tax purposes,  and the
Trustee's  duty to perform its  reporting and other tax  compliance  obligations
under this Section 10.02 shall be subject to the condition that it receives from
the Depositor such  information  possessed by the Depositor that is necessary to
permit the Trustee to perform such obligations.

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

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

     (f) If any tax is imposed on the Grantor Trust, such tax, together with all
incidental  costs and expenses  (including,  without  limitation,  penalties and
reasonable  attorneys'  fees)  shall be charged to and paid by: (i) the  Special
Servicer,  if such tax  arises out of or  results  from a breach by the  Special
Servicer of any of its obligations under Article III or this Section 10.02; (ii)
the Master  Servicer,  if such tax arises out of or results from a breach by the
Master  Servicer of any of its  obligations  under  Article III or this  Section
10.02; (iii) the Trustee,  if such tax arises out of or results from a breach by
the Trustee of any of its  obligations  under  Article IV,  Article VIII or this
Section 10.02;  or (iv) the portion of the Trust Fund  constituting  the Grantor
Trust in all other instances.

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

<PAGE>


Counsel,  cause  either the Trust Fund or any of the  Certificateholders  (other

Person that is not a United States Person and a Permitted Transferee, or

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

     payments which are required to be distributed  on any  Certificate  without
     the consent of the Holder of such Certificate, or

     then outstanding; or

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

     (c)  Notwithstanding  the  foregoing,  the Trustee  will not be entitled to
consent to any  amendment  hereto  without  having first  received an Opinion or
Opinions of Counsel to the effect that (i) such amendment is permitted  pursuant
to the terms of this  Agreement  and (ii) such  amendment or the exercise of any
power granted to the Master Servicer, the Special Servicer,  the Depositor,  the
Trustee or any other specified person in accordance with such amendment will not

manner with the Trustee and the Master Servicer


                                      159

offices of the  Certificate  Registrar,  duly endorsed by, or  accompanied  by a

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

     No transfer of a Senior  Certificate or any interest  therein shall be made
(i) to any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or

whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the  Depositor,  the Master  Servicer,  the  Special  Servicer,  the
Trustee, the Certificate Registrar or any such agent shall be affected by notice

Master  Servicer  or the  Depositor  at a price  determined  as  provided in the

Fund. The Agreement permits,  but does not require,  the Depositor or the Master
Servicer  to  purchase  from the  Trust  Fund  all  Mortgage  Loans  and any REO
Properties  remaining  therein.  The  exercise of such right will  effect  early
retirement of the  Certificates;  however,  such right to purchase is subject to
the  aggregate  Stated  Principal  Balance of the  Mortgage  Pool at the time of
purchase being less than 1% of the aggregate  Cut-off Date Principal  Balance of
the Mortgage Pool specified on the face hereof.

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor,  the Master Servicer, the Special Servicer and the Trustee thereunder

Depositor,  the Master  Servicer,  the Special Servicer and the Trustee with the
consent  of the  Holders  of  Certificates  entitled  to at least 66 2/3% of the

of this Certificate  shall be conclusive and binding on such Holder and upon all
future  Holders  of this  Certificate  and of any  Certificate  issued  upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this  Certificate.  The Agreement  also permits the
amendment thereof, in certain  circumstances,  including any

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

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

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

transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made

certain circumstances,  including any amendment necessary to maintain the status

Holders of any of the Certificates.

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

any Plan is permissible  under applicable law, will not result in any non-exempt
prohibited  transaction  under ERISA or Section  4975 of the Code,  and will not

indirectly  purchasing such  Certificate on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan.

charge that may be imposed in connection  with any transfer or exchange of Class

Master  Servicer  or the  Depositor  at a price  determined  as  provided in the

Fund. The Agreement permits,  but does not require,  the Depositor or the Master
Servicer  to  purchase  from the  Trust  Fund  all  Mortgage  Loans  and any REO
Properties  remaining  therein.  The  exercise of such right will  effect  early
retirement of the  Certificates;  however,  such right to purchase is subject to

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

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

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

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

or other  liquidation (or any advance with respect thereto) of the last Mortgage
Loan or REO Property  remaining in the Trust Fund,  and (ii) the purchase by the
Master  Servicer  or the  Depositor  at a price  determined  as  provided in the

Servicer  to  purchase  from the  Trust  Fund  all  Mortgage  Loans  and any REO
Properties  remaining  therein.  The  exercise of such right will  effect  early

the Mortgage Pool specified on the face hereof.

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

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

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

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

Master  Servicer  or the  Depositor  at a price  determined  as  provided in the

Fund. The Agreement permits,  but does not require,  the Depositor or the Master
Servicer  to  purchase  from the  Trust  Fund  all  Mortgage  Loans  and any REO
Properties  remaining  therein.  The  exercise of such right will  effect  early
retirement of the  Certificates;  however,  such right to purchase is subject to
the  aggregate  Stated  Principal  Balance of the  Mortgage  Pool at the time of
purchase being less than 1% of the aggregate  Cut-off Date Principal  Balance of
the Mortgage Pool specified on the face hereof.

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

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

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

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

registered in the name of Cede & Co. or in such other name as is requested by an

to them pursuant to the Agreement following the earlier of (i) the final payment
or other  liquidation (or any advance with respect thereto) of the last Mortgage

Master  Servicer  or the  Depositor  at a price  determined  as  provided in the
Agreement of all Mortgage  Loans and any REO  Properties  remaining in the Trust
Fund. The Agreement permits,  but does not require,  the Depositor or the Master
Servicer  to  purchase  from the  Trust  Fund  all  Mortgage  Loans  and any REO
Properties  remaining  therein.  The  exercise of such right will  effect  early
retirement of the  Certificates;  however,  such right to purchase is subject to
the  aggregate  Stated  Principal  Balance of the  Mortgage  Pool at the time of
purchase being less than 1% of the aggregate  Cut-off Date Principal  Balance of
the Mortgage Pool specified on the face hereof.

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

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

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

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

as Master Servicer and Special  Servicer,  and Norwest Bank Minnesota,  National
Association, as Trustee. To the extent not defined herein, the capitalized terms
used  herein  have the  respective  meanings  assigned  in the  Agreement.  This
Certificate  is  issued  under  and is  subject  to the  terms,  provisions  and
conditions of the Agreement,  to which Agreement the Holder of this  Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

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

recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth
herein and in the Agreement. As provided in the Agreement,  withdrawals from the
Certificate  Account and the Distribution  Account may be made from time to time
for purposes  other than,  and, in certain  cases,  prior to,  distributions  to

or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

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

     No transfer of any Class F  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class F  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to  register  or qualify the Class F
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under



                                     A-8-3
<PAGE>


the  Agreement  to  permit  the  transfer  of any  Class F  Certificate  without
registration or qualification.  Any Class F Certificateholder desiring to effect
such a transfer shall,  and by the acceptance of its Class F Certificate  agrees
to, indemnify the Depositor,  the Trustee and the Certificate  Registrar against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     No transfer of a Class F Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class F Certificate or interest  therein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan, unless the prospective transferee provides
the Trustee, the Master Servicer and the Depositor with a certification of facts
and an Opinion of Counsel which  establish to the  satisfaction  of the Trustee,
the Master  Servicer and the Depositor that such transfer is  permissible  under
applicable  law, will not  constitute or result in a violation of Section 406 of
ERISA or  Section  4975 of the Code and will  not  subject  the  Depositor,  the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement. In lieu of such opinion of counsel, the prospective transferee
of a Class F Certificate may provide a certification  of facts  substantially to
the effect  that the  purchase of such  Certificate  by or on behalf of, or with
assets of, any Plan is permissible  under applicable law, will not constitute or
result in any non-exempt  prohibited  transaction under ERISA or Section 4975 of
the Code, will not subject the Depositor,  the Trustee or the Master Servicer to
any  obligation  in  addition  to those  undertaken  in the  Agreement,  and the
following  conditions  are met:  (a) the source of funds used to  purchase  such
Certificate is an "insurance  company general  account" (as such term is defined
in United States  Department of Labor  Prohibited  Transaction  Class  Exemption
("PTCE")  95-60) and (b) the  conditions set forth in Sections I and III of PTCE
95-60 have been satisfied as of the date of the acquisition of such  Certificate
and the  condition  set forth in Section  I(a) of PTCE  95-60 will be  satisfied
throughout the prospective transferees' holding of such Certificate.

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

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

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

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



                                     A-8-4
<PAGE>


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

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

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

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

Certificate  is  issued  under  and is  subject  to the  terms,  provisions  and

offices of the Certificate  Registrar  appointed as provided in the Agreement or
such other location as may be specified in such notice. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional  Trust Fund Expense  previously

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

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

     The Depositor's  Mortgage  Pass-Through  Certificates,  Series 1999-C1 (the
"Certificates")  are limited in right of distribution to certain collections and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth
herein and in the Agreement. As provided in the Agreement,  withdrawals from the
Certificate  Account and the Distribution  Account may be made from time to time
for purposes  other than,  and, in certain  cases,  prior to,  distributions  to
Certificateholders,  such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

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

     No transfer of any Class G  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class G  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to  register  or qualify the Class G
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under



                                     A-9-3
<PAGE>


the  Agreement  to  permit  the  transfer  of any  Class G  Certificate  without
registration or qualification.  Any Class G Certificateholder desiring to effect
such a transfer shall,  and by the acceptance of its Class G Certificate  agrees
to, indemnify the Depositor,  the Trustee and the Certificate  Registrar against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     No transfer of a Class G Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class G Certificate or interest  therein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan, unless the prospective transferee provides
the Trustee, the Master Servicer and the Depositor with a certification of facts
and an Opinion of Counsel which  establish to the  satisfaction  of the Trustee,
the Master  Servicer and the Depositor that such transfer is  permissible  under
applicable  law, will not  constitute or result in a violation of Section 406 of
ERISA or  Section  4975 of the Code and will  not  subject  the  Depositor,  the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement. In lieu of such opinion of counsel, the prospective transferee
of a Class G Certificate may provide a certification  of facts  substantially to
the effect  that the  purchase of such  Certificate  by or on behalf of, or with
assets of, any Plan is permissible  under applicable law, will not constitute or
result in any non-exempt  prohibited  transaction under ERISA or Section 4975 of
the Code, will not subject the Depositor,  the Trustee or the Master Servicer to
any  obligation  in  addition  to those  undertaken  in the  Agreement,  and the
following  conditions  are met:  (a) the source of funds used to  purchase  such
Certificate is an "insurance  company general  account" (as such term is defined
in United States  Department of Labor  Prohibited  Transaction  Class  Exemption
("PTCE")  95-60) and (b) the  conditions set forth in Sections I and III of PTCE
95-60 have been satisfied as of the date of the acquisition of such Certificates
and the  condition  set forth in Section  I(a) of PTCE  95-60 will be  satisfied
throughout the prospective transferees' holding of such Certificate.

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

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

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

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



                                     A-9-4
<PAGE>


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

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

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

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

     The Class H Certificates are issuable in fully registered form only without
coupons in minimum denominations  specified in the Agreement. As provided in the
Agreement  and  subject  to  certain  limitations  therein  set  forth,  Class H

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

     No transfer of any Class H  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class H  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to  register  or qualify the Class H
Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class  H  Certificate  without  registration  or  qualification.   Any  Class  H
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class H Certificate agrees to,



                                     A-10-3

indemnify the Depositor,  the Trustee and the Certificate  Registrar against any
liability  that may  result if the  transfer  is not so exempt or is not made in
accordance with such federal and state laws.

     No transfer of a Class H Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class H Certificate or interest  therein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan, unless the prospective transferee provides
the Trustee, the Master Servicer and the Depositor with a certification of facts
and an Opinion of Counsel which  establish to the  satisfaction  of the Trustee,
the Master  Servicer and the Depositor that such transfer is  permissible  under
applicable  law,  will not  constitute  or result in any  non-exempt  prohibited
transaction  under Section 406 of ERISA or Section 4975 of the Code and will not
subject the Depositor,  the Trustee or the Master  Servicer to any obligation in
addition  to those  undertaken  in the  Agreement.  In lieu of such  opinion  of
counsel,  the  prospective  transferee  of a Class H  Certificate  may provide a
certification  of facts  substantially  to the effect that the  purchase of such
Certificate by or on behalf of, or with assets of, any Plan is permissible under
applicable  law,  will not  constitute  or result in any  non-exempt  prohibited
transaction  under  ERISA or  Section  4975 of the Code,  will not  subject  the
Depositor,  the Trustee or the Master  Servicer to any obligation in addition to
those undertaken in the Agreement,  and the following conditions are met (a) the
source of funds used to  purchase  such  Certificate  is an  "insurance  company
general  account" (as such term is defined in United States  Department of Labor
Prohibited  Transaction  Class Exemption  ("PTCE") 95-60) and (b) the conditions
set forth in Sections I and III of PTCE 95-60 have been satisfied as of the date
of the  acquisition of such  Certificate  and the condition set forth in Section
I(a) of PTCE 95-60 will be satisfied  throughout  the  prospective  transferees'
holding of such Certificate.

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

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

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

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

     The Class J Certificates are issuable in fully registered form only without
coupons in minimum denominations  specified in the Agreement. As provided in the
Agreement  and  subject  to  certain  limitations  therein  set  forth,  Class J

the Holder surrendering the same.

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

     No transfer of any Class J  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class J  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to  register  or qualify the Class J
Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class  J  Certificate  without  registration  or  qualification.   Any  Class  J
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class J Certificate agrees to,

indemnify the Depositor,  the Trustee and the Certificate  Registrar against any
liability  that may  result if the  transfer  is not so exempt or is not made in
accordance with such federal and state laws.

     No transfer of a Class J Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class J Certificate or interest  therein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan, unless the prospective transferee provides
the Trustee, the Master Servicer and the Depositor with a certification of facts
and an Opinion of Counsel which  establish to the  satisfaction  of the Trustee,
the Master  Servicer and the Depositor that such transfer is  permissible  under
applicable  law,  will not  constitute  or result in any  non-exempt  prohibited
transaction  under Section 406 of ERISA or Section 4975 of the Code and will not
subject the Depositor,  the Trustee or the Master  Servicer to any obligation in
addition  to those  undertaken  in the  Agreement.  In lieu of such  opinion  of
counsel,  the  prospective  transferee  of a Class J  Certificate  may provide a
certification  of facts  substantially  to the effect that the  purchase of such
Certificate by or on behalf of, or with assets of, any Plan is permissible under
applicable  law,  will not  constitute  or result in any  non-exempt  prohibited
transaction  under  ERISA or  Section  4975 of the Code,  will not  subject  the
Depositor,  the Trustee or the Master  Servicer to any obligation in addition to
those undertaken in the Agreement,  and the following conditions are met (a) the
source of funds used to  purchase  such  Certificate  is an  "insurance  company
general  account" (as such term is defined in United States  Department of Labor
Prohibited  Transaction  Class Exemption  ("PTCE") 95-60) and (b) the conditions
set forth in Sections I and III of PTCE 95-60 have been satisfied as of the date
of the  acquisition of such  Certificate  and the condition set forth in Section
I(a) of PTCE 95-60 will be satisfied  throughout  the  prospective  transferees'
holding of such Certificate.

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

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

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

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

     The Class K[-1][-2] Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided

offices of the  Certificate  Registrar,  duly endorsed by, or  accompanied  by a

writing,  and  thereupon  one  or  more  new  Class  K[-1][-2]  Certificates  in
authorized  denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

     No transfer of any Class  K[-1][-2]  Certificate  shall be made unless that
transfer  is made  pursuant to an  effective  registration  statement  under the
Securities Act, and effective  registration or  qualification  under  applicable
state  securities  laws, or is made in a transaction  that does not require such
registration  or  qualification.  If  such a  transfer  of any  Class  K[-1][-2]
Certificate  (other than a transfer thereof by the Depositor or any Affiliate of
the Depositor) is to be made without registration under the Securities Act, then
the Trustee shall require, in order to assure compliance with such laws, receipt
by it and the Depositor of: (i) if such  transfer is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to  register  or  qualify  the Class
K[-1][-2]  Certificates  under the Securities Act or any other securities law or
to take any action not  otherwise  required  under the  Agreement  to permit the
transfer  of  any  Class   K[-1][-2]   Certificate   without   registration   or
qualification.  Any Class K[-1][-2]  Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class K[-1][-2]  Certificate agrees
to, indemnify the Depositor,  the Trustee and the Certificate  Registrar against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

collective  investment funds and separate accounts in which such plans, accounts
or  arrangements  are invested,  that is subject to ERISA or Section 4975 of the
Code (each, a "Plan") or (B) any Person who is directly or indirectly purchasing
the Class  K[-1][-2]  Certificate  or  interest  therein  on behalf of, as named
fiduciary  of, as trustee of, or with assets of a Plan,  unless the  prospective
transferee  provides the Trustee,  the Master  Servicer and the Depositor with a
certification  of  facts  and an  Opinion  of  Counsel  which  establish  to the
satisfaction  of the Trustee,  the Master  Servicer and the Depositor  that such
transfer is permissible  under  applicable law, will not constitute or result in
any non-exempt prohibited transaction under Section 406 of ERISA or Section 4975
of the Code and will not  subject  the  Depositor,  the  Trustee  or the  Master
Servicer to any obligation in addition to those undertaken in the Agreement.  In
lieu of such opinion of counsel, the prospective transferee of a Class K[-1][-2]
Certificate may provide a  certification  of facts  substantially  to the effect
that the purchase of such Certificate by or on behalf of, or with assets of, any
Plan is permissible  under  applicable law, will not constitute or result in any
non-exempt prohibited  transaction under ERISA or Section 4975 of the Code, will
not subject the Depositor,  the Trustee or the Master Servicer to any obligation
in addition to those undertaken in the Agreement,  and the following  conditions
are met  (a) the  source  of  funds  used to  purchase  such  Certificate  is an
"insurance  company  general  account" (as such term is defined in United States
Department of Labor Prohibited  Transaction Class Exemption  ("PTCE") 95-60) and
(b) the  conditions  set forth in  Sections  I and III of PTCE  95-60  have been
satisfied  as of the  date  of the  acquisition  of  such  Certificate  and  the
condition  set forth in Section I(a) of PTCE 95-60 will be satisfied  throughout
the prospective transferees' holding of such Certificate.

     No service  charge  will be imposed  for any  registration  of  transfer or
exchange of Class  K[-1][-2]  Certificates,  but the Trustee or the  Certificate
Registrar  may  require  payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be imposed in  connection  with any  transfer  or
exchange of Class K[-1][-2] Certificates.

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

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

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

as Master Servicer and Special  Servicer,  and Norwest Bank Minnesota,  National
Association, as Trustee. To the extent not defined herein, the capitalized terms
used  herein  have the  respective  meanings  assigned  in the  Agreement.  This
Certificate  is  issued  under  and is  subject  to the  terms,  provisions  and
conditions of the Agreement,  to which Agreement the Holder of this  Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

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

the Class R-I Certificates on the applicable  Distribution  Date pursuant to the
Agreement.  All  distributions  made  under  the  Agreement  on  any  Class  R-I
Certificate  will be made by the  Trustee by check  mailed to the address of the

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

     The Depositor's  Mortgage  Pass-Through  Certificates,  Series 1999-C1 (the
"Certificates")  are limited in right of distribution to certain collections and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth
herein and in the Agreement. As provided in the Agreement,  withdrawals from the
Certificate  Account and Distribution  Account may be made from time to time for
purposes  other  than,  and,  in  certain  cases,  prior  to,  distributions  to
Certificateholders,  such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

     As provided in the Agreement and subject to certain limitations therein set
forth,  the  transfer of this  Certificate  is  registrable  in the  Certificate
Register upon surrender of this  Certificate for registration of transfer at the

written  instrument  of transfer  in the form  satisfactory  to the  Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in


                                     A-13-2
<PAGE>


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

     No transfer of any Class R-I Certificate shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration or  qualification.  If such a transfer of any Class R-I Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated  to register or qualify the Class R-I
Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class R-I  Certificate  without  registration  or  qualification.  Any Class R-I
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class R-I Certificate agrees to, indemnify the Depositor,  the
Trustee and the Certificate  Registrar  against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

     No transfer of a Class R-I  Certificate  or any interest  therein  shall be
made to (A) any employee benefit plan or other retirement arrangement, including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class R-I  Certificate or interest  therein on behalf of, as named fiduciary of,
as  trustee  of, or with  assets of a Plan,  unless the  prospective  transferee
provides the Trustee, the Master Servicer and the Depositor with a certification
of facts and an Opinion of Counsel which  establish to the  satisfaction  of the
Trustee, the Master Servicer and the Depositor that such transfer is permissible
under  applicable  law, will not  constitute or result in a violation of Section
406 of ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement.

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



                                     A-13-3
<PAGE>


Transferee is not a Permitted  Transferee or is not a United States Person,  the
Trustee  shall not  register  the  Transfer  of an  Ownership  Interest  in this
Certificate to such proposed Transferee.

     Each Person holding or acquiring any Ownership Interest in this Certificate
shall  agree  (x) to  require  a  Transfer  Affidavit  and  Agreement  from  any
prospective  Transferee  to whom such Person  attempts to transfer its Ownership
Interest  herein  and (y) not to  transfer  its  Ownership  Interest  unless  it
provides  to the Trustee a  certificate  substantially  in the form  attached as
Exhibit C-2 to the Agreement  stating that, among other things, it has no actual
knowledge that such prospective  Transferee is not a Permitted  Transferee or is
not a United  States  Person.  Each Person  holding or  acquiring  an  Ownership
Interest in this  Certificate,  by purchasing  such Ownership  Interest  herein,
agrees to give the Trustee  written notice that it is a  "pass-through  interest
holder"   within  the  meaning  of   temporary   Treasury   Regulation   Section
1.67-3T(a)(2)(i)(A)  immediately upon acquiring such Ownership  Interest,  if it
is, or is holding such Ownership Interest on behalf of, a "pass-through interest
holder".

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

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

     A "United States  Person" is a citizen or resident of the United States,  a
corporation,  partnership  or other entity created or organized in, or under the
laws of, the United States or any political  subdivision thereof (except, in the
case of a  partnership,  to the extent  provided  in Treasury  Regulations),  an
estate whose  income from sources  without the United  States is  includable  in
gross income for United  States  federal  income tax purposes  regardless of its
connection with the conduct of a trade or business within the United States,  or
a trust  if a court  within  the  United  States  is  able to  exercise  primary
supervision over the  administration  of the trust and one or more United States
Persons have the authority to control all substantial decisions of the trust.

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

     Prior to due presentment of this  Certificate for registration of transfer,
the Depositor,  the Master  Servicer,  the Special  Servicer,  the Trustee,  the
Certificate  Registrar  and any  agents of any of them may  treat the  Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the Depositor,



                                     A-13-4
<PAGE>


the  Master  Servicer,  the  Special  Servicer,  the  Trustee,  the  Certificate
Registrar or any such agent shall be affected by notice to the contrary.

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

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

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

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

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

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

recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth

or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

                                     A-14-2
<PAGE>


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

     No  transfer  of any  Class  R-II  Certificate  shall be made  unless  that
transfer  is made  pursuant to an  effective  registration  statement  under the
Securities Act, and effective  registration or  qualification  under  applicable
state  securities  laws, or is made in a transaction  that does not require such
registration or qualification.  If such a transfer of any Class R-II Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is  obligated to register or qualify the Class R-II
Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class R-II Certificate  without  registration or  qualification.  Any Class R-II
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class R-II Certificate agrees to, indemnify the Depositor, the
Trustee and the Certificate  Registrar  against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

     No transfer of a Class R-II  Certificate  or any interest  therein shall be
made to (A) any employee benefit plan or other retirement arrangement, including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class R-II  Certificate or interest therein on behalf of, as named fiduciary of,
as  trustee  of, or with  assets of a Plan,  unless the  prospective  transferee
provides the Trustee, the Master Servicer and the Depositor with a certification
of facts and an Opinion of Counsel which  establish to the  satisfaction  of the
Trustee, the Master Servicer and the Depositor that such transfer is permissible
under  applicable  law, will not  constitute or result in a violation of Section
406 of ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement.

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



                                     A-14-3
<PAGE>


Transferee is not a Permitted  Transferee or is not a United States Person,  the
Trustee  shall not  register  the  Transfer  of an  Ownership  Interest  in this
Certificate to such proposed Transferee.

     Each Person holding or acquiring any Ownership Interest in this Certificate
shall  agree  (x) to  require  a  Transfer  Affidavit  and  Agreement  from  any
prospective  Transferee  to whom such Person  attempts to transfer its Ownership
Interest  herein  and (y) not to  transfer  its  Ownership  Interest  unless  it
provides  to the Trustee a  certificate  substantially  in the form  attached as
Exhibit C-2 to the Agreement  stating that, among other things, it has no actual
knowledge that such prospective  Transferee is not a Permitted  Transferee or is
not a United  States  Person.  Each Person  holding or  acquiring  an  Ownership
Interest in this  Certificate,  by purchasing  such Ownership  Interest  herein,
agrees to give the Trustee  written notice that it is a  "pass-through  interest
holder"   within  the  meaning  of   temporary   Treasury   Regulation   Section
1.67-3T(a)(2)(i)(A)  immediately upon acquiring such Ownership  Interest,  if it
is, or is holding such Ownership Interest on behalf of, a "pass-through interest
holder".

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

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

     A "United States  Person" is a citizen or resident of the United States,  a
corporation,  partnership  or other entity created or organized in, or under the
laws of, the United States or any political  subdivision thereof (except, in the
case of a  partnership,  to the extent  provided  in Treasury  Regulations),  an
estate whose  income from sources  without the United  States is  includable  in
gross income for United  States  federal  income tax purposes  regardless of its
connection with the conduct of a trade or business within the United States,  or
a trust  if a court  within  the  United  States  is  able to  exercise  primary
supervision over the  administration  of the trust and one or more United States
Persons have the authority to control all substantial decisions of the trust.

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

     Prior to due presentment of this  Certificate for registration of transfer,
the Depositor,  the Master  Servicer,  the Special  Servicer,  the Trustee,  the
Certificate  Registrar  and any  agents of any of them may  treat the  Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the Depositor,



                                     A-14-4
<PAGE>


the  Master  Servicer,  the  Special  Servicer,  the  Trustee,  the  Certificate
Registrar or any such agent shall be affected by notice to the contrary.

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

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

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

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

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

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

"Certificates")  are limited in right of distribution to certain collections and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth

Certificateholders,  such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

                                     A-15-2
<PAGE>


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

     No  transfer  of any Class  R-III  Certificate  shall be made  unless  that
transfer  is made  pursuant to an  effective  registration  statement  under the
Securities Act, and effective  registration or  qualification  under  applicable
state  securities  laws, or is made in a transaction  that does not require such
registration or qualification. If such a transfer of any Class R-III Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate
from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to
the Agreement as Exhibit B-3, and (B) unless the Depositor directs otherwise, an
Opinion of Counsel  satisfactory  to the Trustee and the Depositor to the effect
that such  transfer  may be made  without such  registration  (which  Opinion of
Counsel  shall not be an  expense  of the Trust  Fund or of the  Depositor,  the
Master Servicer,  the Special Servicer, the Trustee or the Certificate Registrar
in their respective  capacities as such). None of the Depositor,  the Trustee or
the  Certificate  Registrar  is obligated to register or qualify the Class R-III
Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class R-III Certificate without  registration or qualification.  Any Class R-III
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class R-III  Certificate  agrees to,  indemnify the Depositor,
the Trustee and the Certificate  Registrar against any liability that may result
if the transfer is not so exempt or is not made in accordance  with such federal
and state laws.

     No transfer of a Class R-III  Certificate or any interest  therein shall be
made to (A) any employee benefit plan or other retirement arrangement, including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class R-III Certificate or interest therein on behalf of, as named fiduciary of,
as  trustee  of, or with  assets of a Plan,  unless the  prospective  transferee
provides the Trustee, the Master Servicer and the Depositor with a certification
of facts and an Opinion of Counsel which  establish to the  satisfaction  of the
Trustee, the Master Servicer and the Depositor that such transfer is permissible
under  applicable  law, will not  constitute or result in a violation of Section
406 of ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement.

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



                                     A-15-3
<PAGE>


Transferee is not a Permitted  Transferee or is not a United States Person,  the
Certificate  Registrar shall not register the Transfer of an Ownership  Interest
in this Certificate to such proposed Transferee.

     Each Person holding or acquiring any Ownership Interest in this Certificate
shall  agree  (x) to  require  a  Transfer  Affidavit  and  Agreement  from  any
prospective  Transferee  to whom such Person  attempts to transfer its Ownership
Interest  herein  and (y) not to  transfer  its  Ownership  Interest  unless  it
provides  to the Trustee a  certificate  substantially  in the form  attached as
Exhibit C-2 to the Agreement  stating that, among other things, it has no actual
knowledge that such prospective  Transferee is not a Permitted  Transferee or is
not a United  States  Person.  Each Person  holding or  acquiring  an  Ownership
Interest in this  Certificate,  by purchasing  such Ownership  Interest  herein,
agrees to give the Trustee  written notice that it is a  "pass-through  interest
holder"   within  the  meaning  of   temporary   Treasury   Regulation   Section
1.67-3T(a)(2)(i)(A)  immediately upon acquiring such Ownership  Interest,  if it
is, or is holding such Ownership Interest on behalf of, a "pass-through interest
holder".

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

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

     A "United States  Person" is a citizen or resident of the United States,  a
corporation,  partnership  or other entity created or organized in, or under the
laws of, the United States or any political  subdivision thereof (except, in the
case of a  partnership,  to the extent  provided  in Treasury  Regulations),  an
estate whose  income from sources  without the United  States is  includable  in
gross income for United  States  federal  income tax purposes  regardless of its
connection with the conduct of a trade or business within the United States,  or
a trust  if a court  within  the  United  States  is  able to  exercise  primary
supervision over the  administration  of the trust and one or more United States
Persons have the authority to control all substantial decisions of the trust.

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

     Prior to due presentment of this  Certificate for registration of transfer,
the Depositor,  the Master  Servicer,  the Special  Servicer,  the Trustee,  the
Certificate  Registrar  and any  agents of any of them may  treat the  Person in
whose name this  Certificate is registered as the owner hereof for all purposes,
and none of the Depositor,



                                     A-15-4
<PAGE>


the  Master  Servicer,  the  Special  Servicer,  the  Trustee,  the  Certificate
Registrar or any such agent shall be affected by notice to the contrary.

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

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

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

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

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

Dear Sirs:

     This  letter  is  delivered  to you in  connection  with  the  transfer  by
_________________________  (the "Transferor") to _________________________  (the
"Transferee") of the captioned  Certificates (the  "Certificates"),  pursuant to
Section 5.02 of the Pooling and Servicing  Agreement (the "Pooling and Servicing
Agreement"),  dated as of  February  1,  1999,  among GMAC  Commercial  Mortgage
Securities,  Inc. as Depositor, GMAC Commercial Mortgage Corporation,  as Master
Servicer and Special Servicer, and Norwest Bank Minnesota, National Association,
as  Trustee.  All terms used  herein and not  otherwise  defined  shall have the
respective  meanings  set forth in the  Pooling  and  Servicing  Agreement.  The
Transferor  hereby  certifies,  represents  and warrants to you, as  Certificate
Registrar, that:

          1. The  Transferor  is the lawful owner of the  Certificates  with the
     full right to transfer  the  Certificates  free from any and all claims and
     encumbrances whatsoever.

          2.  Neither  the  Transferor  nor anyone  acting on its behalf has (a)
     offered,   transferred,   pledged,   sold  or  otherwise  disposed  of  the
     Certificates,  any  interest  in  the  Certificates  or any  other  similar
     security to any person in any  manner,  (b)  solicited  any offer to buy or
     accept a transfer,  pledge or other  disposition of the  Certificates,  any
     interest in the  Certificates or any other similar security from any person
     in any manner,  (c) otherwise  approached or negotiated with respect to the
     Certificates,  any  interest  in  the  Certificates  or any  other  similar
     security with any person in any manner,  (d) made any general  solicitation
     with respect to the  Certificates,  any interest in the Certificates or any
     other  similar  security  by means of general  advertising  or in any other
     manner, or (e) taken any other action with respect to the Certificates, any
     interest in the Certificates or any other similar  security,  which (in the
     case of any of the acts  described in clauses (a) through (e) hereof) would
     constitute a distribution under the Securities Act of 1933 (the "Securities
     Act"), or would render the  disposition of the  Certificates a violation of
     Section 5 of the  Securities  Act or any state  securities  laws,  or would
     require  registration or qualification of the Certificates  pursuant to the
     Securities Act or any state securities laws.

          3. The Transferor and any person acting on behalf of the Transferor in
     this  matter  reasonably  believe  that  the  Transferee  is  either  (a) a
     "qualified  institutional  buyer"  (as that  term is  defined  in Rule 144A
     ("Rule 144A") under the Securities  Act)  purchasing for its own account or
     (b) either (i) an  "accredited  investor"  within the meaning of  paragraph
     (1),  (2),  (3) or (7) of Rule 501(a) under the  Securities  Act or (ii) an
     entity in which all the equity owners are "accredited investors" within the
     meaning  of  paragraph  (1),  (2),  (3) or (7) of  Rule  501(a)  under  the
     Securities  Act, and has such  knowledge  and  experience  in financial and
     business  matters as to be capable of evaluating the merits and risks of an
     investment in the Certificates.

          4. Unless the Transferee is either (a) an "accredited investor" within
     the meaning of Rule 501(a)(1),  (2), (3) or (7) under the Securities Act or
     (b) an entity in which all the  equity  owners are  "accredited  investors"

     the Securities Act that is furnishing a Transferee  Certificate in the form
     of Exhibit B-3 to the Pooling and Servicing Agreement,  the Transferor or a
     person acting on its behalf has taken  reasonable  steps to ensure that the
     Transferee is aware that the  Transferor  is relying on the exemption  from
     the provisions of Section 5 of the Securities Act provided by Rule 144A.

          5. The Transferor or a person acting on its behalf has  furnished,  or
     caused to be furnished, to the Transferee all information regarding (a) the

Dear Sirs:

     This  letter  is  delivered  to you in  connection  with  the  transfer  by
_________________________  (the "Transferor") to _________________________  (the

respective  meanings  set forth in the  Pooling  and  Servicing  Agreement.  The
Transferee  hereby  certifies,  represents  and warrants to you, as  Certificate
Registrar, that:

          1. The Transferee is a "qualified institutional buyer" as that term is

     or (b) pursuant to another exemption from registration under the Securities
     Act.

          2. The Transferee has been  furnished with all  information  regarding

          3. If the Transferee  proposes that the  Certificates be registered in
     the  name  of  a  nominee,   such   nominee  has   completed   the  Nominee
     Acknowledgment below.

          4. If any  Certificates  are held by the Transferor in definitive form
     (as opposed to Private  Book-Entry  Certificates  registered in the name of
     Cede & Co.) the Transferee  hereby certifies to the Trustee,  the Depositor
     and the Master Servicer that such transfer is permissible  under applicable
     law,  and either (a) such  Transferee  is not an  "employee  benefit  plan"

     Section 4975 of the Code, or any entity deemed to hold "plan assets" within
     the meaning of the Regulation published at 29 C.F.R.  2510.3-101,  (b) will
     not constitute or result in any  non-exempt  prohibited  transaction  under
     Section  406 of ERISA or Section  4975 of the Code and will not subject the
     Depositor, the Trustee or the Master Servicer to any



                                     B-2-1
<PAGE>


     obligation  in  addition  to  those  undertaken  in the  Agreement  and the
     Transferee has attached hereto an opinion of counsel to such effect, or (c)
     in the case of Class F, Class G, Class H, Class J or Class K  Certificates,
     such transfer will not  constitute or result in any  non-exempt  prohibited
     transaction  under ERISA or Section 4975 of the Code,  will not subject the
     Depositor, the Trustee or the Master Servicer to any obligation in addition
     to those undertaken in the Agreement,  and the following condition are met:
     (i) the source of funds used to purchase the  Certificate  is an "insurance
     company  general  account"  (as  such  term is  defined  in  United  States
     Department of Labor Prohibited  Transaction Class Exemption ("PTCE") 95-60)

and/or invested on a discretionary basis by the Transferee,  the Transferee used
the cost of such securities to the Transferee, unless the Transferee reports its
securities  holdings in its  financial  statements  on the basis of their market
value,  and no current  information with respect to the cost of those securities
has been published, in which case the securities were valued at market. Further,
in  determining  such  aggregate  amount,   the  Transferee  may  have  included
securities   owned  by  subsidiaries  of  the  Transferee,   but  only  if  such
subsidiaries  are consolidated  with the Transferee in its financial  statements
prepared in accordance with generally accepted accounting  principles and if the
investments of such  subsidiaries are managed under the Transferee's  direction.
However,  such  securities  were not  included if the  Transferee  is a majority
owned,  consolidated  subsidiary of another enterprise and the Transferee is not
itself a reporting company under the Securities Exchange Act of 1934.

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

     Will  the   Transferee  be  purchasing  the   Certificates   only  for  the
Transferee's own account?

     Yes _____     No _____         

     6. If the answer to the foregoing question is "no," then in each case where
the  Transferee  is  purchasing  for an account other than its own, such account
belongs to a third party that is itself a "qualified institutional buyer" within
the meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been  established by the  Transferee  through one or more of the
appropriate methods contemplated by Rule 144A.

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

                             ANNEX 2 TO EXHIBIT B-2

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [For Transferees That Are Registered Investment Companies]

     The undersigned  hereby  certifies as follows to [name of Transferor]  (the
"Transferor")  and [name of Certificate  Registrar],  as Certificate  Registrar,
with  respect  to the  mortgage  pass-through  certificate  (the  "Certificate")
described in the Transferee  Certificate to which this certification relates and
to which this certification is an Annex:

     1. As indicated  below, the undersigned is the chief financial  officer,  a
person  fulfilling an equivalent  function,  or other  executive  officer of the
entity purchasing the Certificates (the "Transferee") or, if the Transferee is a
"qualified  institutional  buyer" as that term is defined in Rule 144A under the
Securities  Act of 1933 ("Rule 144A") because the Transferee is part of a Family
of  Investment  Companies  (as defined  below),  is an executive  officer of the
investment adviser (the "Adviser").

     2. The Transferee is a "qualified  institutional  buyer" as defined in Rule
144A because (i) the Transferee is an investment  company  registered  under the
Investment  Company Act of 1940, and (ii) as marked below,  the Transferee alone
owned and/or invested on a discretionary  basis, or the  Transferee's  Family of
Investment  Companies owned, at least $100,000,000 in securities (other than the
excluded  securities  referred to below) as of the end of the Transferee's  most
recent fiscal year. For purposes of determining  the amount of securities  owned
by the Transferee or the Transferee's Family of Investment  Companies,  the cost
of such  securities  was  used,  unless  the  Transferee  or any  member  of the
Transferee's  Family of Investment  Companies,  as the case may be,  reports its
securities  holdings in its  financial  statements  on the basis of their market
value,  and no current  information with respect to the cost of those securities
has been  published,  in which case the securities of such entity were valued at
market.

     ____The   Transferee  owned  and/or  invested  on  a  discretionary   basis
$__________ in securities (other than the excluded securities referred to below)
as of the end of the  Transferee's  most recent  fiscal year (such  amount being
calculated in accordance with Rule 144A).

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

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

     4. The term  "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee or are part of the  Transferee's
Family of  Investment  Companies,  (ii) bank deposit notes and  certificates  of
deposit, (iii) loan participations,  (iv) repurchase agreements,  (v) securities
owned but subject to a repurchase agreement and (vi) currency, interest rate and
commodity  swaps. For purposes of determining the aggregate amount of securities
owned and/or  invested on a discretionary  basis by the Transferee,  or owned by
the Transferee's Family of Investment  Companies,  the securities referred to in
this paragraph were excluded.

     5. The  Transferee  is  familiar  with Rule 144A and  understands  that the
parties to which this  certification is being made are relying and will continue
to  rely  on the  statements  made  herein  because  one or  more  sales  to the
Transferee will be in reliance on Rule 144A.

     Will  the   Transferee  be  purchasing  the   Certificates   only  for  the
Transferee's own account?

     Yes _____     No _____         



                                     B-2-7

     6. If the answer to the foregoing question is "no," then in each case where
the  Transferee  is  purchasing  for an account other than its own, such account
belongs to a third party that is itself a "qualified institutional buyer" within
the meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been  established by the  Transferee  through one or more of the
appropriate methods contemplated by Rule 144A.

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

Securities,  Inc., as Depositor, GMAC Commercial Mortgage Corporation, as Master
Servicer  and  as  Special  Servicer,  and  Norwest  Bank  Minnesota,   National
Association,  as Trustee.  All terms used herein and not otherwise defined shall
have the respective  meanings set forth in the Pooling and Servicing  Agreement.
The Transferee hereby certifies,  represents and warrants to you, as Certificate
Registrar, that:

          1. The  Transferee is acquiring the  Certificates  for its own account
     for investment and not with a view to or for sale or transfer in connection
     with any  distribution  thereof,  in whole or in part,  in any manner which
     would  violate the  Securities  Act of 1933,  as amended  (the  "Securities
     Act"), or any applicable state securities laws.

          2. The Transferee  understands  that (a) the Certificates has not been

     qualified  under any  applicable  state  securities  laws,  (b) neither the
     Depositor  nor the  Trustee is  obligated  so to  register  or qualify  the
     Certificates  and (c) neither the  Certificates  nor any security issued in
     exchange therefor or in lieu thereof may be resold or transferred unless it
     is (i)  registered  pursuant  to  the  Securities  Act  and  registered  or
     qualified  pursuant to any applicable state securities laws or (ii) sold or
     transferred  in  transactions  that are exempt from such  registration  and
     qualification requirements and the Trustee and the Depositor have received:
     (A) if such transfer is  purportedly  being made in reliance upon Rule 144A
     under the Securities Act, a certificate from the Certificateholder desiring
     to effect such transfer  substantially  in the form attached as Exhibit B-1
     hereto  and  a  certificate  from  such   Certificateholder's   prospective
     transferee  substantially  in the form attached as Exhibit B-2 hereto;  and
     (B) in all other cases, a certificate from the  Certificateholder  desiring
     to  effect  such  transfer  substantially  in the form  attached  hereto as
     Exhibit B-1 and a  certificate  from such  Certificateholder's  prospective

     to the Trustee and the  Depositor  to the effect that such  transfer may be
     made without registration under the Securities Act.

          3.  The  Transferee  understands  that  it may not  sell or  otherwise
     transfer the  Certificate,  any security issued in exchange  therefor or in
     lieu thereof or any interest in the foregoing except in compliance with the
     provisions  of Section 5.02 of the Pooling and Servicing  Agreement,  which
     provisions it has carefully  reviewed,  and that the Certificate  will bear
     legends substantially to the following effect:



                                     B-3-1
<PAGE>


               THIS  CERTIFICATE  HAS NOT BEEN AND  WILL  NOT BE  REGISTERED  OR
          QUALIFIED  UNDER THE  SECURITIES  ACT, OR THE  SECURITIES  LAWS OF ANY
          STATE. ANY RESALE,  TRANSFER OR OTHER  DISPOSITION OF THIS CERTIFICATE
          WITHOUT  SUCH  REGISTRATION  OR  QUALIFICATION  MAY BE MADE  ONLY IN A
          TRANSACTION  WHICH DOES NOT REQUIRE SUCH REGISTRATION OR QUALIFICATION
          AND IN ACCORDANCE  WITH THE  PROVISIONS OF SECTION 5.02 OF THE POOLING
          AND SERVICING AGREEMENT REFERRED TO HEREIN.

          -AND-

               NO TRANSFER OF THIS  CERTIFICATE  TO AN EMPLOYEE  BENEFIT PLAN OR
          OTHER   RETIREMENT   ARRANGEMENT  THAT  IS  SUBJECT  TO  THE  EMPLOYEE

          ARRANGEMENT,   WILL  BE  REGISTERED  EXCEPT  IN  COMPLIANCE  WITH  THE
          PROCEDURES DESCRIBED IN THE POOLING AND SERVICING AGREEMENT.

     4. Neither the  Transferee nor anyone acting on its behalf has (a) offered,

transfer  of the  Certificate,  any  interest  in the  Certificate  or any other
similar  security  from any person in any manner,  (c)  otherwise  approached or

any other similar  security with any person in any manner,  (d) made any general

taken  any  other  action,  that (in the case of any of the  acts  described  in
clauses  (a)  through  (e)  above)  would   constitute  a  distribution  of  the
Certificate  under the  Securities  Act,  would  render the  disposition  of the
Certificate  a  violation  of  Section  5 of the  Securities  Act  or any  state
securities law or would require registration or qualification of the Certificate
pursuant thereto.  The Transferee will not act, nor has it authorized or will it
authorize any person to act, in any manner set forth in the  foregoing  sentence
with respect to the Certificate,  any security issued in exchange therefor or in
lieu thereof or any interest in the foregoing.

     5. The Transferee has been furnished with all information regarding (a) the
Depositor,  (b) the  Certificate  and  distributions  thereon,  (c) the Mortgage
Loans,  (d) the Pooling and Servicing  Agreement,  and (e) all related  matters,
that it has requested.

     6. The Transferee is either (i) an "accredited investor" within the meaning
of paragraph  (1),  (2), (3) or (7) of Rule 501(a) under the  Securities  Act or
(ii) an entity in which all the equity owners are "accredited  investors" within
the  meaning  of  paragraph  (1),  (2),  (3) or (7) of  Rule  501(a)  under  the
Securities  Act, and has such knowledge and experience in financial and business
matters as to be capable of evaluating  the merits and risks of an investment in
the  Certificates;  the  Transferee  has sought such  accounting,  legal and tax
advice as it has considered  necessary to make an informed investment  decision;
and the  Transferee is able to bear the economic risks of such an investment and
can afford a complete loss of such investment.

     7. The Transferee  hereby  certifies to the Trustee,  the Depositor and the
Master  Servicer that such transfer is  permissible  under  applicable  law, and
either (a) such Transferee is not an "employee  benefit plan" within the meaning
of Section  3(3) of ERISA,  a "plan"  within the meaning of Section  4975 of the
Code,  or any entity  deemed to hold  "plan  assets"  within the  meaning of the
Regulation published at 29 C.F.R. 2510.3-101,  (b) will not constitute or result
in any non-exempt  prohibited  transaction under Section 406 of ERISA or Section
4975 of the Code and will not subject the  Depositor,  the Trustee or the Master

the Transferee has attached hereto an opinion of counsel to such effect,  or (c)
in the case of Class F, Class G, Class H, Class J or Class K Certificates,  such
transfer will not constitute or result in any non-exempt prohibited  transaction
under ERISA or Section  4975 of the Code,  will not subject the  Depositor,  the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement,  and the following  condition are met: (i) the source of funds

"Permitted  Transferee" and will endeavor to remain a "Permitted Transferee" for
so long as it  holds  the  Residual  Certificates,  and  (ii) is  acquiring  the
Residual  Certificates  for  its  own  account  or for the  account  of  another
prospective  transferee from which it has received an affidavit in substantially
the same form as this  affidavit.  A "Permitted  Transferee" is any Person other
than a "disqualified  organization"  or a possession of the United States.  (For
this purpose, a "disqualified  organization" means an electing large partnership
under  section  775 of the Code,  the  United  States,  any  state or  political
subdivision  thereof,  any  agency or  instrumentality  of any of the  foregoing
(other than an  instrumentality,  all of the  activities of which are subject to
tax and,  except for the Federal Home Loan Mortgage  Corporation,  a majority of
whose board of directors is not selected by any such governmental entity) or any
foreign government,  international organization or any agency or instrumentality
of such foreign  government  or  organization,  any rural  electric or telephone
cooperative, or any organization (other than certain farmers' cooperatives) that
is generally exempt from federal income tax unless such  organization is subject
to the tax on unrelated business taxable income.

     3.  The  Transferee  is  aware  (i) of the tax that  would  be  imposed  on
transfers of the Residual Certificates to "disqualified organizations" under the
Code that applies to all transfers of the Residual Certificates;  (ii) that such
tax would be on the transferor  (or, with respect to transfers to electing large
partnerships,  on such  partnership)  or, if such  transfer  is through an agent
(which  Person  includes a broker,  nominee or  middleman)  for a  non-Permitted
Transferee,  on the agent;  (iii) that the Person  (other  than  transfers  with
respect to electing large  partnerships)  otherwise  liable for the tax shall be
relieved of liability for the tax if the transferee  furnishes to such Person an
affidavit  that the  transferee  is a Permitted  Transferee  and, at the time of
transfer,  such Person  does not have actual  knowledge  that the  affidavit  is
false; and (iv) that the Residual  Certificates  may be a "noneconomic  residual
interest" within the meaning of Treasury Regulation Section 1.860E-1(c) and that
the transferor of a "noneconomic  residual  interest" will remain liable for any
taxes due with  respect  to the  income  on such  residual  interest,  unless no
significant  purpose of the transfer is to enable the  transferor  to impede the
assessment or collection of tax.

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

     5. The Transferee is aware that the Certificate Registrar will not register
any  transfer  of  the  Residual  Certificates  by  the  Transferee  unless  the
Transferee's transferee, or such transferee's agent, delivers to the



                                     C-1-1
<PAGE>


Certificate  Registrar,  among other  things,  an  affidavit  and  agreement  in
substantially  the same form as this  affidavit and  agreement.  The  Transferee
expressly  agrees that it will not  consummate  any such transfer if it knows or
believes that any  representation  contained in such  affidavit and agreement is
false.

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

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

     8. The  Transferee  has reviewed the  provisions of Section  5.02(d) of the
Pooling and Servicing Agreement,  a description of which provisions is set forth
in the Residual  Certificates (in particular,  clause (ii)(A) of Section 5.02(d)
which authorizes the Trustee to deliver payments on the Residual  Certificate to
a Person other than the Transferee  and clause (ii)(B) of Section  5.02(d) which
authorizes   the  Trustee  to  negotiate  a  mandatory   sale  of  the  Residual
Certificates,  in either  case,  in the event  that the  Transferee  holds  such
Residual  Certificates  in violation  of Section  5.02(d));  and the  Transferee
expressly agrees to be bound by and to comply with such provisions.

     9. No purpose of the Transferee relating to its purchase or any sale of the
Residual  Certificates  is or will be to impede the  assessment or collection of
any tax.

     10.  The  Transferee  hereby  represents  to and  for  the  benefit  of the
transferor that the Transferee  intends to pay any taxes associated with holding
the Residual  Certificates as they become due, fully  understanding  that it may
incur tax  liabilities  in excess of any cash flows  generated  by the  Residual
Certificates.

     11. The Transferee  will, in connection  with any transfer that it makes of
the Residual Certificates, deliver to the Certificate Registrar a representation
letter  substantially  in the form of Exhibit H-2 to the  Pooling and  Servicing
Agreement in which it will represent and warrant, among other things, that it is
not  transferring  the  Residual   Certificates  to  impede  the  assessment  or
collection of any tax and that it has at the time of such  transfer  conducted a
reasonable  investigation of the financial  condition of the proposed transferee
as  contemplated  by  Treasury  Regulation  Section  1.860E-1(c)(4)(i)  and  has
satisfied the requirements of such provision.

     12.  The  Transferee  is a citizen or  resident  of the  United  States,  a
corporation, a partnership or other entity created or organized in, or under the
laws of, the United States or any political  subdivision thereof (except, in the
case of a  partnership,  to the extent  provided  in Treasury  Regulations),  an
estate whose  income from sources  without the United  States is  includible  in
gross income for United  States  federal  income tax purposes  regardless of its
connection with the conduct of a trade or business within the United States,  or
a trust for which a court within the United  States is able to exercise  primary
supervision  over its  administration  and for which one or more  United  States
Persons have the authority to control all substantial decisions of the trust.

     13. The  Transferee is not acquiring the Residual  Certificates  with "plan
assets" of any plan subject to Title I of ERISA or Section 4975 of the Code.

             GMAC Commercial Mortgage Securities, Inc.,
             Mortgage Pass-Through Certificates, Series 1999-C1

         Re:    GMAC Commercial Mortgage Securities, Inc., Mortgage Pass-Through
                Certificates, Series 1999-C1 (the "Certificates")

Dear Sirs:

     This  letter  is  delivered  to you in  connection  with  the  transfer  by
_________________________  (the "Transferor") to _________________________  (the
"Transferee") of [Class R-I] [Class R-II] [Class R-III] Certificates  evidencing
a _____% Percentage  Interest in such Class (the "Residual  Certificates").  The
Certificates,  including the Residual Certificates,  were issued pursuant to the
Pooling and Servicing Agreement,  dated as of February 1, 1999 (the "Pooling and
Servicing  Agreement"),  among GMAC  Commercial  Mortgage  Securities,  Inc., as
Depositor, GMAC Commercial Mortgage Corporation,  as Master Servicer and Special
Servicer,  and Norwest Bank Minnesota,  National  Association,  as Trustee.  All
capitalized  terms  used  but  not  otherwise  defined  herein  shall  have  the
respective  meanings  set forth in the  Pooling  and  Servicing  Agreement.  The
Transferor  hereby  certifies,  represents  and warrants to you, as  Certificate
Registrar, that:

          1. No  purpose  of the  Transferor  relating  to the  transfer  of the
     Residual  Certificates by the Transferor to the Transferee is or will be to
     impede the assessment or collection of any tax.

          2. The Transferor understands that the Transferee has delivered to you
     a Transfer  Affidavit and Agreement in the form attached to the Pooling and
     Servicing  Agreement.  The  Transferor  does not know or  believe  that any
     representation contained therein is false.

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

                                              Very truly yours,

     Methodology to Normalize Net Operating Income and Debt Service Coverage

o    GMAC Commercial  Mortgage  Corporation  ("GMACCM")  applies the methodology
     presented  below to arrive  at a  servicer  adjusted  or  "Normalized"  Net
     Operating  Income ("NOI").  The items described below highlight some of the
     major categories requiring  adjustment.  There may, however, be others, and
     GMACCM  will  use  its  market  knowledge  and  discretion  in  making  and
     sufficiently footnoting the necessary adjustments.

o    GMACCM  chooses to use the actual  management  fee stated in the  financial
     statement.

o    Where they are clearly identifiable, GMACCM will remove any capital expense
     from any above  the line  categories  (such as  extraordinary  repairs  and
     maintenance)  and put them below the line in the  capital  expense  comment
     section.

o    Replacement  reserves,  tenant improvement and leasing commission  reserves
     will be treated as above the line expenses.  A  determination  will be made
     whether  there have been credits for the  disbursements  from a reserve and
     that expenses are not overstated due to exclusion of credits.

o    Property  taxes should be the annual amount due,  excluding any  delinquent
     taxes or credits from prior years which would cause the number to be higher
     or lower.  The amount for  property  taxes will be  adjusted  if the period
     under analysis is less than one year.

o    GMAC Commercial Mortgage will exclude non-recurring,  extraordinary income.
     For example,  a tax refund,  lease  buyout or income  received for a period
     other than the year in question should be adjusted.  If past due rent for a
     prior year was paid and recorded in the current year,  GMACCM would back it
     out  and  footnote  it  accordingly.  Care  will be  used  when  reflecting
     percentage/overage  rents to  ensure  that it  relates  to the  appropriate
     period and that the numbers are supported by tenant sales information.

o    GMAC  Commercial  Mortgage  will  remove  any items not  pertaining  to the
     operation of the property such as, fees for closing the loan restructure, a
     distribution to owners or a charitable contribution.

o    When  necessary,  income  and  expenses  will be  analyzed  by  looking  at
     variances by category. Unusual income and expense items will be researched.
     If there are significant variances, inquiries to the borrower will be made.
     Appropriate  adjustments  will be made and  footnotes  provided  to clearly
     explain the situation.

o    The debt  service  should be an actual  amount  the  borrower  paid per the
     servicing records for the period  associated with the operating  statement.
     If GMACCM does not have a full year of payments,  it will use the principal
     and interest  constant in the case of a fixed rate loan and, in the case of
     an adjustable  rate loan, will estimate a full year amount from the payment
     history information available.

                                                                  Execution Copy


                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of February 2, 1999, between GMAC Commercial  Mortgage  Corporation
as seller (the "Seller" or "GMACCM") and GMAC  Commercial  Mortgage  Securities,
Inc. as purchaser (the "Purchaser").

     The Seller desires to sell,  assign,  transfer and otherwise  convey to the
Purchaser,  and the  Purchaser  desires  to  purchase,  subject to the terms and
conditions set forth below,  the multifamily and commercial  mortgage loans (the
"Mortgage  Loans")  identified on the schedule  annexed hereto as Exhibit A (the
"Mortgage Loan  Schedule").  Certain other multi family and commercial  mortgage
loans will be  purchased  by the  Purchaser  from (i) LaSalle  National  Bank as
Trustee for  Restructured  Asset  Certificates  With  Enhanced  Returns,  Series
1998-ML Trust ("ML Trust") pursuant to, and for the consideration  described in,
the  Mortgage  Loan  Purchase  Agreement,  dated as of February 2, 1999 (the "ML
Trust Mortgage Loan Purchase  Agreement") between the Purchaser and the ML Trust
and (ii) German American Capital Corporation ("GACC"),  pursuant to, and for the
consideration  described in, the Mortgage Loan Purchase  Agreement,  dated as of
February 2, 1999 (the "GACC  Mortgage  Loan  Purchase  Agreement"),  between the
Depositor and GACC (the mortgage loans  purchased by the Purchaser  under the ML
Trust  Mortgage  Loan  Purchase  Agreement  and the GACC  Mortgage Loan Purchase
Agreement,  the  "Other  Mortgage  Loans").  The  Seller,  ML Trust and GACC are
collectively referred to as the "Mortgage Loan Sellers."

     It is expected that the Mortgage Loans will be  transferred,  together with
other  multifamily  and  commercial  mortgage  loans to a trust fund (the "Trust
Fund") to be formed by the  Purchaser,  beneficial  ownership  of which  will be
evidenced   by   a   series   of   mortgage   pass-through   certificates   (the
"Certificates"). Certain classes of the Certificates will be rated by Standard &
Poor's Ratings Services and Fitch IBCA, Inc. (together,  the "Rating Agencies").
Certain classes of the  Certificates  (the  "Registered  Certificates")  will be
registered under the Securities Act of 1933, as amended (the "Securities  Act").
The Trust Fund will be created and the Certificates will be issued pursuant to a
pooling and servicing agreement to be dated as of February 1, 1999 (the "Pooling
and Servicing  Agreement"),  among the Purchaser as depositor,  GMAC  Commercial
Mortgage  Corporation  as  master  servicer  (in  such  capacity,   the  "Master
Servicer") and special servicer (in such capacity,  the "Special  Servicer") and
Norwest Bank Minnesota,  National Association, as trustee (in such capacity, the
"Trustee").  Capitalized  terms not otherwise  defined  herein have the meanings
assigned  to them in the  Pooling and  Servicing  Agreement  as in effect on the
Closing Date.

     The Purchaser  intends to sell the Class A-1,  Class A-2, Class B, Class C,
Class D, Class E and a portion of the Class X Certificates  to Goldman,  Sachs &
Co., Deutsche Bank Securities Inc. and Donaldson,  Lufkin & Jenrette  Securities
Corporation (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  


<PAGE>


The Purchaser  intends to sell a portion of the Class X  Certificates  to GMACCM
(in such  capacity,  a "Class X  Certificate  Purchaser")  pursuant to a Class X
Certificate  Purchase  Agreement dated the date hereof (the "Class X Certificate
Purchase Agreement").  The Purchaser intends to sell the Class F, Class G, Class
H, Class J and Class K  Certificates  to GMACCM (in such  capacity,  an "Initial
Purchaser")  pursuant to a Certificate  Purchase Agreement dated the date hereof
(the "Certificate Purchase Agreement").  The Purchaser intends to sell the Class
R-I,  Class R-II and the Class R-III  Certificates  to Goldman,  Sachs & Co. (in
such capacity, an "Initial Purchaser").  The Class F, Class G, Class H, Class J,
Class K, Class R-I,  Class R-II and Class R-III  Certificates  are  collectively
referred to as the "Non-Registered Certificates."

     Now, therefore,  in consideration of the premises and the mutual agreements
set forth herein, the parties agree as follows:

SECTION 1. Agreement to Purchase.

     The Seller agrees to sell,  assign,  transfer and  otherwise  convey to the
Purchaser,  and the  Purchaser  agrees to  purchase,  the  Mortgage  Loans.  The
purchase and sale of the Mortgage  Loans shall take place on February 9, 1999 or
such other date as shall be  mutually  acceptable  to the  parties  hereto  (the
"Closing Date"). The "Cut-off Date" with respect to any Mortgage Loan is the Due
Date for such  Mortgage  Loan in February  1999.  As of the close of business on
their respective  Cut-off Dates (which Cut-off Dates may occur after the Closing
Date),  the  Mortgage  Loans  will  have an  aggregate  principal  balance  (the
"Aggregate  Cut-off  Date  Balance"),  after  application  of  all  payments  of
principal  due  thereon on or before  such date,  whether  or not  received,  of
$1,313,693,704,  subject to a variance of plus or minus 5%. The  purchase  price
for the Mortgage Loans shall be $1,310,116,152.

SECTION 2. Conveyance of Mortgage Loans.

     (a) Effective as of the Closing Date, subject only to receipt by the Seller
of the  purchase  price  referred  to in  Section  1  hereof  (exclusive  of any
applicable  holdback  for  transaction  expenses),  the Seller does hereby sell,
transfer,  assign,  set over and  otherwise  convey  to the  Purchaser,  without
recourse, all the right, title and interest of the Seller in and to the Mortgage
Loans  identified on the Mortgage  Loan Schedule as of such date,  including all
interest and  principal  received or receivable by the Seller on or with respect
to the Mortgage  Loans after the Cut-off Date for such Mortgage  Loan,  together
with all of the Seller's right, title and interest in and to the proceeds of any
related title,  hazard, or other insurance  policies and any escrow,  reserve or
other comparable  accounts related to the Mortgage Loans. The Purchaser shall be
entitled to (and,  to the extent  received  by or on behalf of the  Seller,  the
Seller  shall  deliver or cause to be  delivered  to or at the  direction of the
Purchaser) all scheduled  payments of principal and interest due on the Mortgage
Loans after the Cut-off Date for each Mortgage Loan, and all other recoveries of
principal and interest  collected thereon after such Cut-off Date. All scheduled
payments of principal and interest due thereon on or before the Cut-off Date for
each  Mortgage  Loan and  collected  after such Cut-off Date shall belong to the
Seller.

     (b) In connection with the Seller's  assignment  pursuant to subsection (a)
above, the Seller hereby agrees that, at least five (5) Business Days before the
Closing Date, it shall have  delivered to and  deposited  with the Trustee,  the
Mortgage  File (as  described  on 



                                       2
<PAGE>



Exhibit B hereto) for each Mortgage Loan so assigned. It is further acknowledged
and  agreed by the Seller  that the  Purchaser  intends to cause the  Trustee to
perform a limited review of such Mortgage Files to enable the Trustee to confirm
to the  Purchaser on or before the Closing Date that the Mortgage  Note referred
to in clause (i) of Exhibit B has been  delivered  by the Seller with respect to
each such  Mortgage  File.  In the event  Seller  fails to so deliver  each such
Mortgage File to the Trustee, the Purchaser and its successors and assigns shall
be entitled  to pursue any rights or remedies in respect of such  failure as may
be available under applicable law. If the Seller cannot deliver,  or cause to be
delivered as to any Mortgage Loan, the original  Mortgage Note, the Seller shall
deliver a copy or duplicate  original of such  Mortgage  Note,  together with an
affidavit  certifying that the original  thereof has been lost or destroyed.  If
the Seller cannot  deliver,  or cause to be delivered,  as to any Mortgage Loan,
the original or a copy of any of the documents and/or instruments referred to in
clauses  (ii),  (iv),  (viii),  (xi)(A) and (xii) of Exhibit B, with evidence of
recording  thereon,  solely because of a delay caused by the public recording or
filing  office  where  such  document  or  instrument  has  been  delivered  for
recordation or filing,  or because such original recorded document has been lost
or returned from the recording or filing  office and  subsequently  lost, as the
case may be, the delivery  requirements  of this Section 2(b) shall be deemed to
have been  satisfied  as to such  missing  item,  and such missing item shall be
deemed to have been included in the related Mortgage File,  provided that a copy
of such document or instrument (without evidence of recording or filing thereon,
but  certified  (which  certificate  may  relate to  multiple  documents  and/or
instruments)  by the  Seller  to be a true  and  complete  copy of the  original
thereof  submitted  for  recording  or  filing,  as the  case  may be) has  been
delivered  to the Trustee,  and either the original of such missing  document or
instrument, or a copy thereof, with evidence of recording or filing, as the case
may be,  thereon,  is delivered to or at the  direction of the Purchaser (or any
subsequent owner of the affected Mortgage Loan, including without limitation the
Trustee) within 180 days of the Closing Date (or within such longer period after
the Closing Date as the  Purchaser  (or such  subsequent  owner) may consent to,
which  consent  shall not be  unreasonably  withheld  so long as the  Seller has
provided  the  Purchaser  (or  such  subsequent  owner)  with  evidence  of such
recording or filing,  as the case may be, or has  certified to the Purchaser (or
such subsequent  owner) as to the occurrence of such recording or filing, as the
case may be, and is, as certified to the Purchaser (or such subsequent owner) no
less  often  than  quarterly,  in good  faith  attempting  to  obtain  from  the
appropriate  county  recorder's or filing office such original or copy).  If the
Seller cannot  deliver,  or cause to be delivered,  as to any Mortgage Loan, the
original or a copy of the related lender's title insurance policy referred to in
clause (ix) of Exhibit B solely because such policy has not yet been issued, the
delivery requirements of this Section 2(b) shall be deemed to be satisfied as to
such missing  item,  and such missing item shall be deemed to have been included
in the related  Mortgage  File,  provided  that the Seller has  delivered to the
Trustee a  commitment  for title  insurance  "marked-up"  at the closing of such
Mortgage  Loan,  and the  Seller  shall  deliver to or at the  direction  of the
Purchaser (or any  subsequent  owner of the affected  Mortgage  Loan,  including
without  limitation the Trustee),  promptly  following the receipt thereof,  the
original  related  lender's  title  insurance  policy  (or a copy  thereof).  In
addition,  notwithstanding  anything to the contrary  contained herein, if there
exists with respect to any group of related cross-collateralized  Mortgage Loans
only one  original of any  document  referred  to in Exhibit B covering  all the
Mortgage  Loans  in such  group,  then the  inclusion  of the  original  of such
document in the Mortgage File for any of the Mortgage  Loans in such group shall
be deemed an  inclusion  of such  original  in the  Mortgage  File for each such
Mortgage Loan. On the Closing 



                                       3
<PAGE>


Date, upon  notification  from the Seller that the purchase price referred to in
Section 1 (exclusive of any applicable  holdback for  transaction  expenses) has
been  received by the Seller,  the Trustee shall be authorized to release to the
Purchaser or its designee all of the Mortgage Files in the Trustee's  possession
relating to the Mortgage Loans.

     (c) As to each Mortgage Loan, the Seller shall be responsible for all costs
associated  with (i) the  recording  or  filing,  as the  case  may be,  of each
assignment  referred to in clauses (iii) and (v) of Exhibit B and each UCC-2 and
UCC-3, if any,  referred to in clause (xi)(B) of Exhibit B and (ii) the delivery
of a copy of any such  document or instrument  to the Master  Servicer  promptly
following  its return to the Trustee or its  designee  after such  recording  or
filing; provided that the Seller shall not be responsible for actually recording
or filing any such document or instrument. If any such document or instrument is
lost or returned  unrecorded or unfiled, as the case may be, because of a defect
therein,  the  Seller  shall  promptly  prepare  or cause the  preparation  of a
substitute  therefor or cure or cause the curing of such defect, as the case may
be, and shall thereafter  deliver the substitute or corrected  document to or at
the direction of the Purchaser (or any subsequent owner of the affected Mortgage
Loan,  including  without  limitation  the Trustee) for recording or filing,  as
appropriate, at the Seller's expense.

     (d) All  documents  and records in the  Seller's  possession  (or under its
control)  relating to the Mortgage Loans that are not required to be a part of a
Mortgage  File in  accordance  with  Exhibit B (all  such  other  documents  and
records,  as to any Mortgage  Loan,  the  "Servicing  File"),  together with all
escrow  payments,  reserve funds and other comparable funds in the possession of
the Seller (or under its  control)  with respect to the  Mortgage  Loans,  shall
(unless  they are held by a  sub-servicer  that shall,  as of the Closing  Date,
begin acting on behalf of the Master  Servicer  pursuant to a written  agreement
between such parties) be delivered by the Seller (or its agent) to the Purchaser
(or its designee) no later than the Closing Date. If a sub-servicer shall, as of
the Closing Date,  begin acting on behalf of the Master Servicer with respect to
any Mortgage Loan  pursuant to a written  agreement  between such  parties,  the
Seller  shall  deliver  a copy  of the  related  Servicing  File  to the  Master
Servicer.

     (e) The Seller's records will reflect the transfer of the Mortgage Loans to
the Purchaser as a sale.

SECTION 3. Examination of Mortgage Loan Files and Due Diligence Review.

     The Seller shall reasonably  cooperate with any examination of the Mortgage
Files  and  Servicing  Files  that  may be  undertaken  by or on  behalf  of the
Purchaser.  The fact that the  Purchaser  has conducted or has failed to conduct
any partial or complete examination of the Mortgage Files and/or Servicing Files
shall not affect the Purchaser's  right to pursue any remedy available in equity
or at law for a breach of the Seller's representations, warranties and covenants
set forth in or contemplated by Section 4.

SECTION 4. Representations, Warranties and Covenants of the Seller.

     (a) The Seller  hereby  makes,  as of the Closing Date (or as of such other
date specifically provided in the particular representation or warranty), to and
for the benefit of the Purchaser,  and its  successors  and assigns  (including,
without  limitation,  the Trustee and the 


                                       4
<PAGE>



holders of the  Certificates),  each of the  representations  and warranties set
forth in Exhibit C, with such  changes or  modifications  as may be permitted or
required by the Rating Agencies.

     (b) In addition,  the Seller, as of the date hereof,  hereby represents and
warrants to, and covenants with, the Purchaser that:

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

          (ii) The execution and delivery of this  Agreement by the Seller,  and
     the  performance  and  compliance  with the terms of this  Agreement by the
     Seller,  will  not  violate  the  Seller's   organizational   documents  or
     constitute a default (or an event which,  with notice or lapse of time,  or
     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets,  in each case which  materially  and
     adversely  affect the  ability of the Seller to carry out the  transactions
     contemplated by this Agreement.

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery  by  the  Purchaser,   constitutes  a  valid,  legal  and  binding
     obligation of the Seller, enforceable against the Seller in accordance with
     the  terms  hereof,  subject  to  (A)  applicable  bankruptcy,  insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors' rights generally,  (B) general principles of equity,  regardless
     of whether such  enforcement  is considered in a proceeding in equity or at
     law, and (C) public policy  considerations  underlying the securities laws,
     to  the  extent  that  such   public   policy   considerations   limit  the
     enforceability  of the provisions of this Agreement that purport to provide
     indemnification for securities laws liabilities.

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

          (vi) No litigation is pending with regard to which Seller has received
     service of process or, to the best of the  Seller's  knowledge,  threatened
     against the Seller the  outcome of which,  in the  Seller's  good faith and
     reasonable  judgment,  could  reasonably be expected to prohibit the Seller
     from entering into this  Agreement or 


                                       5
<PAGE>


     materially  and  adversely  affect the ability of the Seller to perform its
     obligations under this Agreement.

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  the
     Class X Certificate Purchaser,  the Initial Purchasers and their respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the other transactions contemplated hereby.

          (viii)  Neither  the Seller  nor  anyone  acting on its behalf has (A)
     offered,   pledged,   sold,  disposed  of  or  otherwise   transferred  any
     Certificate,  any interest in any Certificate or any other similar security
     to any person in any manner,  (B) solicited any offer to buy or to accept a
     pledge,  disposition or other transfer of any Certificate,  any interest in
     any  Certificate  or any  other  similar  security  from any  person in any
     manner,  (C)  otherwise  approached  or  negotiated  with  respect  to  any
     Certificate,  any interest in any Certificate or any other similar security
     with any person in any manner,  (D) made any general  solicitation by means
     of  general  advertising  or in  any  other  manner  with  respect  to  any
     Certificate,  any interest in any Certificate or any similar  security,  or
     (E) taken any other action,  that (in the case of any of the acts described
     in clauses (A) through (E) above) would constitute or result in a violation
     of the  Securities  Act or  any  state  securities  law  relating  to or in
     connection with the issuance of the Certificates or require registration or
     qualification pursuant to the Securities Act or any state securities law of
     any Certificate not otherwise intended to be a Registered  Certificate.  In
     addition,  the  Seller  will  not  act,  nor has it  authorized  or will it
     authorize  any  person to act,  in any  manner  set forth in the  foregoing
     sentence with respect to any of the Certificates or interests therein.  For
     purposes of this paragraph 4(b)(viii), the term "similar security" shall be
     deemed to include,  without  limitation,  any security  evidencing or, upon
     issuance,  that would have  evidenced an interest in the Mortgage  Loans or
     the Other Mortgage Loans or any substantial number thereof.

          (ix)  Insofar  as it  relates  to the  Mortgage  Loans  and the  Other
     Mortgage  Loans,  the  information  set  forth on pages A-8  through  A-11,
     inclusive,  of Annex A to the Prospectus  Supplement (as defined in Section
     9) (the  "Loan  Detail")  and,  to the  extent  consistent  therewith,  the
     information set forth on the diskette attached to the Prospectus Supplement
     and the accompanying  prospectus (the  "Diskette"),  is true and correct in
     all material respects.  Insofar as it relates to the Mortgage Loans and the
     Other Mortgage Loans and/or the Seller and does not represent a restatement
     of the  information on the Loan Detail,  the  information  set forth in the
     Prospectus  Supplement  and the  Memorandum (as defined in Section 9) under
     the headings "Summary Information--The Mortgage Pool", "Risk Factors--Risks
     Related to the  Mortgage  Loans" and  "Description  of the  Mortgage  Asset
     Pool", set forth on Annex A to the Prospectus Supplement and (to the extent
     it contains information  consistent with that on such Annex A) set forth on
     the Diskette,  does not contain any untrue  statement of a material fact or
     (in  the  case  of the  Memorandum,  when  read  together  with  the  other
     information  specified  therein as being available for review by investors)
     omit to state any material fact necessary to make the  statements  therein,
     in light of the circumstances under which they were made, not misleading.



                                       6
<PAGE>


          (x) No consent,  approval,  authorization or order of, registration or
     filing with, or notice to, any governmental authority or court is required,
     under federal or state law (including, with respect to any bulk sale laws),
     for the execution,  delivery and performance of or compliance by the Seller
     with this Agreement,  or the  consummation by the Seller of any transaction
     contemplated  hereby,  other than (1) the filing or  recording of financing
     statements, instruments of assignment and other similar documents necessary
     in connection  with Seller's sale of the Mortgage  Loans to the  Purchaser,
     (2)   such    consents,    approvals,    authorizations,    qualifications,
     registrations,  filings or notices  as have been  obtained  or made and (3)
     where the lack of such  consent,  approval,  authorization,  qualification,
     registration,  filing or notice would not have a material adverse effect on
     the performance by the Seller under this Agreement.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)
above which materially and adversely affects the interests of the Purchaser or a
breach of any of the  representations and warranties made pursuant to subsection
(a) above and set forth in Exhibit C which materially and adversely  affects the
value of any  Mortgage  Loan or the  interests  therein of the  Purchaser or its
successors  and  assigns  (including,  without  limitation  the  Trustee and the
holders of the  Certificates),  the party  discovering  such  breach  shall give
prompt written notice to the other party hereto.

SECTION 5. Representations, Warranties and Covenants of the Purchaser.

     (a) The Purchaser,  as of the date hereof,  hereby  represents and warrants
to, and covenants with, the Seller that:

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

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

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery by the Seller,  constitutes a valid,  legal and binding obligation
     of the Purchaser,  enforceable against the Purchaser in accordance with the
     terms   hereof,   subject  to  (A)   applicable   bankruptcy,   insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors'  rights  generally,   and  (B)  general  principles  of  equity,
     regardless  of whether such  enforcement  is  considered in a proceeding in
     equity or at law.


                                       7

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

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

          (vii) The Purchaser has not dealt with any broker,  investment banker,
     agent or other person, other than the Seller, the Underwriters, the Class X
     Certificate   Purchaser,   the  Initial  Purchasers  and  their  respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the transactions contemplated hereby.

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

     (b) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties  set forth above which  materially and adversely
affects the  interests of the Seller,  the party  discovering  such breach shall
give prompt written notice to the other party hereto.

SECTION 6. Repurchases.

     (a) Within 90 days of the earlier of  discovery or receipt of notice by the
Seller,  from either the  Purchaser  or any  successor or assign  thereof,  of a
Defect (as defined in the Pooling and  Servicing  Agreement  as in effect on the
Closing  Date) in respect of the Mortgage File for any Mortgage Loan or a breach
of any representation or warranty made pursuant to Section 4(a) and set forth in
Exhibit C (a "Breach"),  which Defect or Breach,  as the case may be, materially
and adversely affects the value of any Mortgage Loan or the interests therein of
the Purchaser or its successors and assigns (including,  without limitation, the
Trustee and the holders of the Certificates),  the Seller shall cure such Defect
or  Breach,  as the case may be, in all  material  respects  or  repurchase  the
affected Mortgage Loan from the then owner(s) thereof at the applicable Purchase
Price (as  defined in the Pooling and  Servicing  Agreement  as in effect on the



                                       8
<PAGE>


Closing Date) by payment of such Purchase  Price by wire transfer of immediately
available funds to the account designated by such owner(s);  provided,  however,
that in lieu of effecting any such  repurchase,  the Seller will be permitted to
deliver a Qualifying  Substitute Mortgage Loan and to pay a cash amount equal to
the  applicable   Substitution  Shortfall  Amount,  subject  to  the  terms  and
conditions  of the Pooling and  Servicing  Agreement as in effect on the Closing
Date.

     If the Seller is notified of a Defect in any Mortgage File that corresponds
to  information  set forth in the  Mortgage  Loan  Schedule,  the  Seller  shall
promptly correct such Defect and provide a new, corrected Mortgage Loan Schedule
to the  Purchaser,  which  corrected  Mortgage Loan Schedule  shall be deemed to
amend and replace the existing Mortgage Loan Schedule for all purposes.

     (b)  Notwithstanding  Section  6(a),  within  60  days  of the  earlier  of
discovery or receipt of notice by the Seller,  from either the  Purchaser or any
successor  or assign  thereof,  that any  Mortgage  Loan does not  constitute  a
"qualified  mortgage" within the meaning of Section  860G(a)(3) of the Code, the
Seller shall repurchase such Mortgage Loan from the then owner(s) thereof at the
applicable  Purchase Price by payment of such Purchase Price by wire transfer of
immediately available funds to the account designated by such owner(s).

     In addition,  if, as of the Closing Date, any Mortgage Loan is secured by a
Mortgage that does not constitute a valid first lien upon the related  Mortgaged
Property,  including all  buildings  located  thereon and all fixtures  attached
thereto,  or if a Mortgage  is subject to  something  other than (A) the lien of
current  real  property  taxes  and  assessments  not yet due and  payable,  (B)
covenants,  conditions  and  restrictions,  rights of way,  easements  and other
matters of public record, (C) exceptions and exclusions specifically referred to
in the lender's title insurance  policy issued or, as evidenced by a "marked-up"
commitment,  to be  issued  in  respect  of such  Mortgage  Loan  and (D)  those
exceptions  set forth on Schedule  C-1 to Exhibit C hereto (the  exceptions  set
forth in the foregoing  clauses (A), (B), (C) and (D)  collectively,  "Permitted
Encumbrances"),  or if the insurer that issued the Title  Policy  referred to in
clause  (vi) of  Exhibit  C  hereto  in  respect  of any  Mortgage  Loan was not
qualified to do business in the state in which the related Mortgaged Property is
located,  and in either case such failure  materially and adversely  affects the
interests of holders of  Certificates,  (any such failure  that  materially  and
adversely  affects the interests of holders of  Certificates,  also a "Breach"),
the Seller shall be required,  at its option,  to either (i) cure such Breach in
all material  respects or (ii)  repurchase  the affected  Mortgage Loan, in each
case,  within the applicable  Permitted Cure Period (as defined  below).  If any
such  Breach is not  corrected  or cured in all  material  respects  within  the
applicable  Permitted Cure Period, the Seller shall, not later than the last day
of such  Permitted Cure Period,  (i) repurchase the affected  Mortgage Loan from
the Purchaser or its assignee at the applicable Purchase Price or (ii) if within
the  three-month  period  commencing on the closing date (or within the two-year
period  commencing  on the  Closing  Date  if the  related  Mortgage  Loan  is a
"defective  obligation"  within the meaning of Section  860(a)(4)(B)(ii)  of the
Code and Treasury Regulation Section 1.860G-2(f)),  at its option,  replace such
Mortgage  Loan  with  a  Qualifying   Substitute   Mortgage  Loan  and  pay  any
corresponding  Substitution  Shortfall  Amount.  The Seller agrees that any such
repurchase or substitution  shall be completed in accordance with and subject to
the terms and conditions of the Pooling and Servicing Agreement.



                                       9
<PAGE>


     For purposes of the preceding  paragraph  only, the "Permitted Cure Period"
applicable  to any Breach in respect  of any  Mortgage  Loan shall be the 90-day
period  immediately  following  the  earlier of the  discovery  by the Seller or
receipt by the Seller of notice of such  Breach;  provided  that if such  Breach
cannot be corrected or cured in all material respects within such 90-day period,
but is reasonably likely that such Breach could be corrected or cured within 180
days of the  earlier of  discovery  by the  Seller and  receipt by the Seller of
notice of such  Breach and the Seller is  diligently  attempting  to effect such
correction or cure,  then the applicable  Permitted Cure Period shall,  with the
consent  of  the  Purchaser  or  its  assignee   (which  consent  shall  not  be
unreasonably withheld), be extended for an additional 90 days.

     (c) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan  contemplated by this Section 6, the then owner(s)  thereof shall tender or
cause to be tendered promptly to the Seller, upon delivery of a receipt executed
by the Seller,  the related  Mortgage File and Servicing File, and each document
that  constitutes  a part of the Mortgage  File that was endorsed or assigned to
the Purchaser or the Trustee shall be endorsed or assigned,  as the case may be,
to the Seller or its designee in the same manner.  The form and  sufficiency  of
all such instruments and certificates shall be the responsibility of the Seller.

     (d) Except as provided in Section  2(b),  this  Section 6 provides the sole
remedies available to the Purchaser,  and its successors and assigns (including,
without limitation,  the Trustee and the holders of the Certificates) respecting
any Defect in a Mortgage  File or any breach of any  representation  or warranty
made pursuant to Section 4(a) and set forth in Exhibit C, or in connection  with
the  circumstances  described  in Section  6(b).  If the Seller  defaults on its
obligations to repurchase  any Mortgage Loan in accordance  with Section 6(a) or
6(b) or disputes its  obligation to  repurchase  any Mortgage Loan in accordance
with either such  subsection,  the Purchaser or its  successors  and assigns may
take such  action as is  appropriate  to enforce  such  payment or  performance,
including,  without  limitation,  the institution and prosecution of appropriate
proceedings.  The Seller shall  reimburse  the  Purchaser  for all necessary and
reasonable costs and expenses incurred in connection with such enforcement.

SECTION 7. Closing.

     The closing of the sale of the Mortgage Loans (the "Closing") shall be held
at the offices of Orrick,  Herrington  & Sutcliffe  LLP, 666 Fifth  Avenue,  New
York, New York 10103 at 10:00 a.m., New York City time, on the Closing Date.

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

          (i) All of the  representations and warranties of the Seller specified
     herein shall be true and correct as of the Closing Date,  and the Aggregate
     Cut-off  Date Balance  shall be within the range  permitted by Section 1 of
     this Agreement;

          (ii) All documents  specified in Section 8 (the "Closing  Documents"),
     in such forms as are agreed upon and acceptable to the Purchaser,  shall be
     duly executed and delivered by all signatories as required  pursuant to the
     respective terms thereof;


                                       10
<PAGE>


          (iii) The Seller shall have delivered and released to the Trustee, the
     Purchaser or the  Purchaser's  designee,  as the case may be, all documents
     and funds required to be so delivered pursuant to Section 2;

          (iv) The result of any examination of the Mortgage Files and Servicing
     Files  performed  by or on behalf of the  Purchaser  pursuant  to Section 3
     shall be satisfactory to the Purchaser in its sole determination;

          (v) All other terms and  conditions of this  Agreement  required to be
     complied with on or before the Closing Date shall have been complied  with,
     and the  Seller  shall  have the  ability  to  comply  with all  terms  and
     conditions and perform all duties and  obligations  required to be complied
     with or performed after the Closing Date;

          (vi) The Seller  shall have paid or agreed to pay all fees,  costs and
     expenses payable by it to the Purchaser pursuant to this Agreement; and

          (vii)  None of the  Underwriting  Agreement,  the Class X  Certificate
     Purchase  Agreement or the Certificate  Purchase  Agreement shall have been
     terminated in accordance with its terms.

     Both parties  agree to use their best efforts to perform  their  respective
obligations hereunder in a manner that will enable the Purchaser to purchase the
Mortgage Loans on the Closing Date.

SECTION 8. Closing Documents.

The Closing Documents shall consist of the following:

     (a) This  Agreement  duly  executed and  delivered by the Purchaser and the
Seller;

reasonably request.

SECTION 9. Indemnification.

     (a) The Seller  agrees to indemnify and hold  harmless the  Purchaser,  its
officers  and  directors,  and each person,  if any, who controls the  Purchaser
within the meaning of either  Section 15 of the  Securities Act or Section 20 of
the Securities  Exchange Act of 1934, as amended (the "Exchange  Act"),  against
any and all losses, claims,  damages or liabilities,  joint or several, to which
they or any of them may become  subject under the  Securities  Act, the Exchange
Act or other  federal or state  statutory  law or  regulation,  at common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Prospectus Supplement,  the
Memorandum, the Diskette or, insofar as they are required to be filed as part of
the Registration  Statement pursuant to the No-Action Letters, any Computational
Materials or ABS Term Sheets with respect to the Registered Certificates,  or in
any revision or amendment thereof or supplement  thereto, or arise out of or are
based  upon  the  omission  or  alleged  omission  (in  the  case  of  any  such
Computational  Materials or ABS Term Sheets,  when read in conjunction  with the
Prospectus and, in the case of the Memorandum, when read together with the other
information  specified  therein as being  available  for review by investors) to
state therein a material fact required to be stated therein or necessary to make
the  statements  therein,  in light of the  circumstances  under which they were
made,  not  misleading;  but only if and to the extent  that (i) any such untrue
statement or alleged untrue  statement is with respect to information  regarding
the Mortgage Loans or the Other Mortgage Loans  contained in the Loan Detail or,
to the  extent  consistent  therewith,  the  Diskette,  or (ii) any such  untrue
statement or alleged  untrue  statement or omission or alleged  omission is with
respect to  information  regarding the Seller or the Mortgage Loans or the Other
Mortgage Loans  contained in the Prospectus  Supplement or the Memorandum  under
the headings "Summary  Information -- The Mortgage Pool",  "Risk Factors --Risks
Related to the Mortgage  Loans" and/or  "Description of the Mortgage Asset Pool"
or  contained on Annex A to the  Prospectus  Supplement  (exclusive  of the Loan
Detail),  and such  information  does not represent a restatement of information
contained in the Loan Detail;  or (iii) such untrue  statement,  alleged  untrue
statement,  omission or alleged omission arises out of or is based upon a breach
of the  representations  and  warranties  of the  Seller  set  forth  in or made
pursuant  to Section 4;  provided,  that the  indemnification  provided  by this
Section 9 shall not apply to the extent that such untrue statement of a material
fact or omission of a material fact  necessary to make the  statements  made, in
light of the circumstances in which they were made, not misleading,  was made as
a result of an error in the  manipulation  of, or  calculations  based upon, the
Loan Detail. This indemnity agreement will be in addition to any liability which
the Seller may otherwise have.

     For  purposes of the  foregoing,  "Registration  Statement"  shall mean the
registration  statement  No.  333-64963  filed  by the  Purchaser  on Form  S-3,
including  without  limitation  exhibits  thereto and  information  incorporated
therein by reference;  "Prospectus"  shall mean the 


                                       12
<PAGE>


prospectus dated November 5, 1998, as supplemented by the prospectus  supplement
dated February 2, 1999 (the "Prospectus Supplement"), relating to the Registered
Certificates;  "Memorandum"  shall mean the private  placement  memorandum dated
February 2, 1999,  relating to the Non-Registered  Certificates;  "Computational
Materials" shall have the meaning assigned thereto in the no-action letter dated
May 20, 1994 issued by the Division of Corporation Finance of the Securities and
Exchange Commission (the "Commission") to Kidder, Peabody Acceptance Corporation
I, Kidder,  Peabody & Co. Incorporated,  and Kidder Structured Asset Corporation
and  the  no-action  letter  dated  May  27,  1994  issued  by the  Division  of
Corporation  Finance  of the  Commission  to the Public  Securities  Association
(together,  the "Kidder Letters");  and "ABS Term Sheets" shall have the meaning
assigned  thereto in the no-action  letter dated February 17, 1995 issued by the
Division  of  Corporation  Finance of the  Commission  to the Public  Securities
Association  (the "PSA  Letter"  and,  together  with the  Kidder  Letters,  the
"No-Action Letters").

     (b) Promptly after receipt by any person entitled to indemnification  under
this Section 9 (each, an "indemnified  party") of notice of the  commencement of
any action,  such indemnified party will, if a claim in respect thereof is to be
made against the Seller (the "indemnifying  party") under this Section 9, notify
the indemnifying party in writing of the commencement  thereof; but the omission
to notify the indemnifying  party will not relieve it from any liability that it
may have to any  indemnified  party otherwise than under this Section 9. In case
any such action is brought  against any  indemnified  party and it notifies  the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to participate  therein, and to the extent that it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof,  with counsel
satisfactory  to  such  indemnified  party;  provided,   however,  that  if  the
defendants  in any such  action  include  both  the  indemnified  party  and the
indemnifying  party and the  indemnified  party or parties shall have reasonably
concluded that there may be legal defenses  available to it or them and/or other
indemnified  parties that are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select  separate  counsel  to  assert  such  legal  defenses  and  to  otherwise
participate in the defense of such action on behalf of such indemnified party or
parties.  Upon receipt of notice from the indemnifying party to such indemnified
party of its  election to assume the defense of such action and  approval by the
indemnified party of counsel,  which approval will not be unreasonably withheld,
the  indemnifying  party  will not be  liable  for any  legal or other  expenses
subsequently  incurred by such indemnified  party in connection with the defense
thereof,  unless (i) the indemnified  party shall have employed separate counsel
in  connection  with the  assertion  of legal  defenses in  accordance  with the
proviso  to the  preceding  sentence  (it being  understood,  however,  that the
indemnifying  party  shall  not be  liable  for the  expenses  of more  than one
separate  counsel,  approved  by  the  Purchaser  and  the  indemnifying  party,
representing  all the indemnified  parties under Section 9(a) who are parties to
such  action),  (ii) the  indemnifying  party  shall not have  employed  counsel
reasonably  satisfactory to the  indemnified  party to represent the indemnified
party within a reasonable  time after  notice of  commencement  of the action or
(iii) the  indemnifying  party has  authorized the employment of counsel for the
indemnified party at the expense of the indemnifying  party; and except that, if
clause (i) or (iii) is applicable,  such  liability  shall only be in respect of
the counsel referred to in such clause (i) or (iii).

     (c)  If  the  indemnification  provided  for in  this  Section  9 is due in
accordance  with  its  terms  but  is for  any  reason  held  by a  court  to be
unavailable to an indemnified party on 



                                       13
<PAGE>


grounds  of  policy  or  otherwise,  then  the  indemnifying  party,  in lieu of
indemnifying  such  indemnified  party,  shall  contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities,  in such proportion as is appropriate to reflect the relative fault
of the indemnified and indemnifying parties in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any  other  relevant  equitable  considerations.  The  relative  fault of the
indemnified and indemnifying  parties shall be determined by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
or the  omission  or  alleged  omission  to state a  material  fact  relates  to
information supplied by such parties

     (d) The  Purchaser  and the  Seller  agree  that it  would  not be just and
equitable if  contribution  pursuant to Section 9(c) were determined by pro rata
allocation  or by any other method of  allocation  that does not take account of
the considerations referred to in Section 9(c) above. The amount paid or payable
by an  indemnified  party  as a  result  of  the  losses,  claims,  damages  and
liabilities referred to in this Section 9 shall be deemed to include, subject to
the limitations set forth above, any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim,  except  where the  indemnified  party is required to bear such
expenses pursuant to this Section 9, which expenses the indemnifying party shall
pay as and when incurred, at the request of the indemnified party, to the extent
that the indemnifying  party will be ultimately  obligated to pay such expenses.
If any expenses so paid by the indemnifying party are subsequently determined to
not be required to be borne by the indemnifying party hereunder,  the party that
received  such  payment  shall  promptly  refund the amount so paid to the party
which  made such  payment.  No person  guilty  of  fraudulent  misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.

     (e) The indemnity and contribution  agreements  contained in this Section 9
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
termination of this Agreement,  (ii) any  investigation  made by any indemnified
party, and (iii) acceptance of and payment for any of the Certificates.

SECTION 10. Costs.

     Costs relating to the  transactions  contemplated  hereby shall be borne by
the respective parties hereto.

SECTION 11. Notices.

     All demands,  notices and communications  hereunder shall be in writing and
shall be deemed to have been duly given if personally delivered to or mailed, by
registered  mail,  postage  prepaid,  by overnight mail or courier  service,  or
transmitted  by facsimile and confirmed by a similar mailed  writing,  if to the

SECTION 12. Third Party Beneficiaries.

     Each of the officers,  directors  and  controlling  persons  referred to in
Section 9 hereof is an intended  third party  beneficiary  of the  covenants and
indemnities  of the  Seller  set  forth in  Section 9 of this  Agreement.  It is
acknowledged  and agreed that such covenants and  indemnities may be enforced by
or on behalf of any such person or entity  against the Seller to the same extent
as if it was a party hereto.

SECTION 13. Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,
incorporated herein by reference or contained in the certificates of officers of
the Seller submitted  pursuant hereto,  shall remain operative and in full force
and effect and shall survive delivery of the Mortgage Loans by the Seller to the
Purchaser or its designee.

SECTION 14. Severability of Provisions.

                                    EXHIBIT C

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

                     REGARDING THE INDIVIDUAL MORTGAGE LOANS

     With  respect to each  Mortgage  Loan,  the Seller  hereby  represents  and
warrants, as of the date hereinbelow specified or, if no such date is specified,
as of the Closing Date, except as set forth on Schedule C-1 hereto, that:

          (i)  Ownership of Mortgage  Loans.  Immediately  prior to the transfer
     thereof to the Purchaser,  the Seller had good and marketable title to, and
     was the sole owner and holder of, such Mortgage Loan, free and clear of any
     and all liens,  encumbrances and other interests on, in or to such Mortgage
     Loan (other than, in certain cases,  the right of a subservicer to directly
     service such Mortgage Loan).  Such transfer  validly  assigns  ownership of
     such  Mortgage Loan to the  Purchaser  free and clear of any pledge,  lien,
     encumbrance or security interest.

          (ii) Authority to Transfer  Mortgage Loans.  The Seller has full right
     and authority to sell, assign and transfer such Mortgage Loan. No provision
     of the  Mortgage  Note,  Mortgage or other loan  document  relating to such
     Mortgage  Loan  prohibits  or  restricts  the  Seller's  right to assign or
     transfer such Mortgage Loan.

          (iii)  Mortgage  Loan  Schedule.  The  information  pertaining to such
     Mortgage  Loan set forth in the Mortgage Loan Schedule was true and correct
     in all material respects as of the Cut-off Date.

          (iv) Payment Record. Such Mortgage Loan was not as of the Cut-off Date
     for such Mortgage  Loan,  and has not been during the  twelve-month  period
     prior  thereto,  30 days or more  delinquent in respect of any debt service
     payment required thereunder,  without giving effect to any applicable grace
     period.

          (v) Permitted Encumbrances.  The Permitted Encumbrances (as defined in
     the Mortgage Loan Purchase  Agreement of which this Exhibit C forms a part)
     do not materially  interfere  with the security  intended to be provided by
     the related Mortgage, the current use or operation of the related Mortgaged
     Property or the current  ability of the Mortgaged  Property to generate net
     operating income  sufficient to service the Mortgage Loan. If the Mortgaged
     Property is operated as a nursing  facility,  a  hospitality  property or a
     multifamily  property,  the Mortgage,  together with any separate  security
     agreement,   similar  agreement  and  UCC  financing  statement,   if  any,
     establishes  and  creates a first  priority,  perfected  security  interest
     (subject only to any prior purchase money security interest), to the extent
     such security interest can be perfected by the recordation of a Mortgage or
     the filing of a UCC financing statement,  in all personal property owned by
     the  Mortgagor  that  is used  in,  and is  reasonably  necessary  to,  the
     operation of the related Mortgaged Property.

          (vi) Title  Insurance.  The lien of the related Mortgage is insured by
     an ALTA lender's title insurance policy ("Title Policy"), or its equivalent
     as  adopted  in  the


                                      C-1
<PAGE>


     applicable jurisdiction,  issued by a nationally recognized title insurance
     company,  insuring the originator of such Mortgage Loan, its successors and
     assigns,  as to the first  priority  lien of the  Mortgage in the  original
     principal  amount of the  Mortgage  Loan after all  advances of  principal,
     subject only to Permitted Encumbrances (or, if a title insurance policy has
     not yet been issued in respect of the Mortgage  Loan, a policy  meeting the
     foregoing  description  is evidenced by a  commitment  for title  insurance
     "marked-up" at the closing of such loan).  Each Title Policy (or, if it has
     yet to be issued, the coverage to be provided thereby) is in full force and
     effect, all premiums thereon have been paid and, to the Seller's knowledge,
     no material  claims have been made  thereunder and no claims have been paid
     thereunder.  The Seller has not, by act or  omission,  done  anything  that
     would materially  impair the coverage under such Title Policy.  Immediately
     following the transfer and  assignment of the related  Mortgage Loan to the
     Trustee, such Title Policy (or, if it has yet to be issued, the coverage to
     be provided  thereby) will inure to the benefit of the Trustee  without the
     consent of or notice to the insurer.

          (vii) No Waivers by Seller of  Material  Defaults.  The Seller has not
     waived any material  default,  breach,  violation or event of  acceleration
     existing under the related Mortgage or Mortgage Note.

          (viii)  No  Offsets,  Defenses  or  Counterclaims.  There  is no valid
     offset, defense or counterclaim to such Mortgage Loan.

          (ix) Condition of Property;  Condemnation.  Except as set forth in any
     engineering  report  prepared in  connection  with the  origination  of (or
     obtained in connection with or otherwise following the Seller's acquisition
     of) such Mortgage Loan, the related Mortgaged  Property is, to the Seller's
     knowledge, free and clear of any damage that would materially and adversely
     affect its value as  security  for such  Mortgage  Loan.  The Seller has no
     actual notice of the  commencement of a proceeding for the  condemnation of
     all or any material portion of the related Mortgaged Property.

          (x) Compliance  with Usury Laws.  Such Mortgage Loan complied with all
     applicable usury laws in effect at its date of origination.

          (xi) Full Disbursement of Mortgage Loan Proceeds. The proceeds of such
     Mortgage  Loan have been fully  disbursed and there is no  requirement  for
     future advances thereunder.

          (xii)  Enforceability.  The related Mortgage Note and Mortgage and all
     other  documents  and  instruments  evidencing,  guaranteeing,  insuring or
     otherwise  securing such Mortgage Loan have been duly and properly executed
     by the parties thereto, and each is the legal, valid and binding obligation
     of the maker thereof (subject to any non-recourse  provisions  contained in
     any of the foregoing  agreements and any applicable  state  anti-deficiency
     legislation),  enforceable  in  accordance  with its terms,  except as such
     enforcement  may be  limited  by  bankruptcy,  insolvency,  reorganization,
     receivership,  moratorium or other laws relating to or affecting the rights
     of creditors  generally and by general  principles of equity (regardless of
     whether such  enforcement  is  considered  in a proceeding  in equity or at
     law).


                                      C-2
<PAGE>


          (xiii) Insurance. All improvements upon the related Mortgaged Property
     are  insured  against  loss by hazards of  extended  coverage  in an amount
     (subject  to a  customary  deductible)  at least equal to the lesser of the
     outstanding  principal  balance of such  Mortgage Loan and 100% of the full
     replacement  cost of the improvements  located on such Mortgaged  Property,
     and the related hazard insurance policy contains  appropriate  endorsements
     to avoid the  application  of  co-insurance  provisions and does not permit
     reduction in insurance  proceeds  for  depreciation.  If any portion of the
     related  Mortgaged  Property  was, at the time of the  origination  of such
     Mortgage Loan, in an area identified in the Federal Register by the Federal
     Emergency  Management  Agency as having  special flood  hazards,  and flood
     insurance was available,  a flood insurance policy meeting any requirements
     of the then current  guidelines of the Federal Insurance  Administration is
     in effect  with a  generally  acceptable  insurance  carrier,  in an amount
     representing  coverage  not  less  than the  least  of (1) the  outstanding
     principal  balance of such Mortgage Loan,  (2) the full insurable  value of
     such  Mortgaged  Property,  (3) the maximum  amount of insurance  available
     under the National Flood Insurance Act of 1968, as amended, and (4) 100% of
     the  replacement  cost  of  the  improvements  located  on  such  Mortgaged
     Property.  In addition,  the Mortgage requires the Mortgagor to maintain in
     respect of the Mortgaged Property comprehensive general liability insurance
     in amounts generally required by the Seller, and at least six months rental
     or business interruption insurance,  and all such insurance required by the
     Mortgage to be maintained is in full force and effect.  Each such insurance
     policy  requires  prior notice to the holder of the Mortgage of termination
     or cancellation, and no such notice has been received, including any notice
     of nonpayment of premiums, that has not been cured.

          (xiv)  Environmental  Condition.  The related  Mortgaged  Property was
     subject to one or more  environmental  site  assessments (or an update of a
     previously conducted  assessment),  which was (were) performed on behalf of
     the Seller,  or as to which the related  report was delivered to the Seller
     in connection  with its  origination  or acquisition of such Mortgage Loan;
     and the Seller, having made no independent inquiry other than reviewing the
     resulting report(s) and/or employing an environmental consultant to perform
     the assessment(s)  referenced  herein, has no knowledge of any material and
     adverse environmental  conditions or circumstance  affecting such Mortgaged
     Property  that was not disclosed in the related  report(s).  The Seller has
     not taken any action  with  respect to such  Mortgage  Loan or the  related
     Mortgaged Property that could subject the Purchaser,  or its successors and
     assigns  in  respect  of the  Mortgage  Loan,  to any  liability  under the
     Comprehensive  Environmental  Response,  Compensation  and Liability Act of
     1980, as amended ("CERCLA") or any other applicable federal, state or local
     environmental  law, and the Seller has not received any actual  notice of a
     material  violation  of CERCLA or any  applicable  federal,  state or local
     environmental law with respect to the related  Mortgaged  Property that was
     not disclosed in the related report. The related Mortgage or loan documents
     in the related  Mortgage  File  requires  the  Mortgagor to comply with all
     applicable federal, state and local environmental laws and regulations.

          (xv)  No  Cross-Collateralization  with  Other  Mortgage  Loans.  Such
     Mortgage Loan is not cross-collateralized  with any mortgage loan that will
     not be included in the Trust Fund.


                                      C-3
<PAGE>


          (xvi) Waivers and Modifications. The terms of the related Mortgage and
     the Mortgage Note have not been  impaired,  waived,  altered or modified in
     any  material  respect,  except as  specifically  set forth in the  related
     Mortgage File.

          (xvii) Taxes and Assessments.  There are no delinquent  taxes,  ground
     rents,  assessments for improvements or other similar  outstanding  charges
     affecting the related Mortgaged  Property which are or may become a lien of
     priority  equal to or higher  than the lien of the  related  Mortgage.  For
     purposes of this  representation  and  warranty,  real  property  taxes and
     assessments shall not be considered unpaid until the date on which interest
     and/or penalties would be payable thereon.

          (xviii) Mortgagor's Interest in Mortgaged Property. Except in the case
     of eleven  (11)  Mortgage  Loans as to which the  interest  of the  related
     Mortgagor  in the  related  Mortgaged  Property  is in  whole  or in part a
     leasehold  estate,  the  interest of the related  Mortgagor  in the related
     Mortgaged Property consists of a fee simple estate in real property.

          (xix)  Whole  Loan.  Each  Mortgage  Loan  is a whole  loan  and not a
     participation interest.

          (xx) Valid Assignment. The assignment of the related Mortgage referred
     to in clause (iii) of Exhibit B  constitutes  the legal,  valid and binding
     assignment of such Mortgage from the relevant assignor to the Trustee.  The
     Assignment of Leases set forth in the Mortgage or separate from the related
     Mortgage and related to and delivered in connection with each Mortgage Loan
     establishes and creates a valid,  subsisting and, subject only to Permitted
     Encumbrances,  enforceable  first priority lien and first priority security
     interest in the  related  Mortgagor's  interest  in all leases,  subleases,
     licenses  or other  agreements  pursuant to which any person is entitled to
     occupy,  use or possess all or any portion of the real property  subject to
     the related  Mortgage,  and each assignor  thereunder has the full right to
     assign the same. The related  assignment of any  Assignment of Leases,  not
     included in a Mortgage,  executed and  delivered in favor of the Trustee is
     in recordable form and constitutes a legal,  valid and binding  assignment,
     sufficient to convey to the assignee  named  therein all of the  assignor's
     right, title and interest in, to and under such Assignment of Leases.

          (xxi) Escrows. All escrow deposits relating to such Mortgage Loan that
     are, as of the Closing Date, required to be deposited with the mortgagee or
     its agent have been so deposited.

          (xxii)  No  Mechanics'  or  Materialmen's  Liens.  As of the  date  of
     origination  of such  Mortgage  Loan and,  to the actual  knowledge  of the
     Seller, as of the Closing Date, the related  Mortgaged  Property was and is
     free and clear of any  mechanics' and  materialmen's  liens or liens in the
     nature  thereof  which  create a lien prior to that  created by the related
     Mortgage,  except  those  which are  insured  against  by the Title  Policy
     referred to in (vi) above.


                                      C-4
<PAGE>


          (xxiii) No Material Encroachments. To the Seller's knowledge (based on
     surveys and/or title insurance  obtained in connection with the origination
     of such Mortgage Loan), as of the date of such origination,  no improvement
     that was included for the purpose of determining the appraised value of the
     related Mortgaged Property at the time of origination of such Mortgage Loan
     lay outside the boundaries and building  restriction lines of such property
     to any material extent (unless affirmatively covered by the title insurance
     referred to in paragraph  (vi)  above),  and no  improvements  on adjoining
     properties  encroached upon such Mortgaged Property to any material extent.
     To the Seller's knowledge,  based upon opinions of counsel and/or other due
     diligence  customarily performed by the Seller, the improvements located on
     or forming part of such Mortgaged  Property comply in all material respects
     with applicable zoning laws and ordinances  (except to the extent that they
     may constitute legal non-conforming uses).

          (xxiv) Originator Authorized.  To the extent required under applicable
     law as of the  Closing  Date,  the  originator  of such  Mortgage  Loan was
     authorized  to do  business  in  the  jurisdiction  in  which  the  related
     Mortgaged  Property is located at all times when it held the Mortgage  Loan
     to the extent necessary to ensure the enforceability of such Mortgage Loan.

          (xxv) No Material Default. (A) To the Seller's knowledge, there exists
     no  material  default,  breach or event of  acceleration  under the related
     Mortgage  or  Mortgage  Note,  and (B) the Seller has not  received  actual
     notice of any event (other than payments due but not yet delinquent)  that,
     with the passage of time or with notice and the  expiration of any grace or
     cure period,  would constitute such a material default,  breach or event of
     acceleration; provided, however, that this representation and warranty does
     not cover any default,  breach or event of acceleration  that  specifically
     pertains  to any  matter  otherwise  covered  or  addressed  by  any  other
     representation and warranty made by the Seller herein.

          (xxvi)  Inspection.  In connection with the origination or acquisition
     of each Mortgage Loan,  the Seller  inspected or caused to be inspected the
     Mortgaged Property.

          (xxvii) No Equity Participation or Contingent  Interest.  The Mortgage
     Loan contains no equity  participation by the lender,  and does not provide
     for any contingent or additional  interest in the form of  participation in
     the  cash  flow  of  the  related  Mortgaged  Property,   or  for  negative
     amortization.

          (xxviii) No Advances of Funds.  No holder of the Mortgage Loan has, to
     the Seller's knowledge,  advanced funds or induced,  solicited or knowingly
     received  any  advance  of funds  from a party  other than the owner of the
     related Mortgaged Property,  directly or indirectly, for the payment of any
     amount required by the Mortgage Loan.

          (xxix) Licenses, Permits, Etc. To the Seller's knowledge, based on due
     diligence  customarily  performed in the origination of comparable mortgage
     loans by the Seller,  as of the date of  origination  of the Mortgage Loan,
     the related Mortgagor or operator of the related Mortgaged  Property was in
     possession of all material licenses, 



                                      C-5
<PAGE>


     permits and  authorizations  required by applicable  laws for the ownership
     and operation of the related Mortgaged Property as it was then operated.

          (xxx)  Servicing.  The servicing and  collection  practices  used with
     respect to the  Mortgage  Loan have  complied  with  applicable  law in all
     material respects and are consistent with the servicing  standard set forth
     in Section 3.01(a) of the Pooling and Servicing Agreement.

          (xxxi)  Customary  Remedies.  The related  Mortgage or Mortgage  Note,
     together with  applicable  state law,  contains  customary and  enforceable
     provisions (subject to the exceptions set forth in paragraph (xii)) such as
     to render the rights and remedies of the holders  thereof  adequate for the
     practical  realization  against  the  related  Mortgaged  Property  of  the
     principal benefits of the security intended to be provided thereby.

          (xxxii)  Insurance and  Condemnation  Proceeds.  The related  Mortgage
     provides that insurance proceeds and condemnation  proceeds will be applied
     for  one of the  following  purposes:  either  to  restore  or  repair  the
     Mortgaged  Property,  or to repay the  principal of the Mortgage  Loan,  or
     otherwise at the option of the holder of the Mortgage.

          (xxxiii) LTV. The gross  proceeds of such Mortgage Loan to the related
     Mortgagor at origination did not exceed the non-contingent principal amount
     of the Mortgage  Loan and either:  (A) such  Mortgage Loan is secured by an
     interest in real  property  having a fair market  value (1) at the date the
     Mortgage  Loan was  originated at least equal to 80 percent of the original
     principal  balance of the Mortgage Loan or (2) at the Closing Date at least
     equal to 80 percent of the  principal  balance of the Mortgage Loan on such
     date;  provided that for purposes hereof, the fair market value of the real
     property  interest  must  first be reduced by (X) the amount of any lien on
     the real  property  interest  that is senior to the Mortgage Loan and (Y) 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 clauses (1) and (2) of this  paragraph  (xxxiii)
     shall be made on a pro rata basis in accordance with the fair market values
     of the Mortgaged  Properties  securing such  cross-collateralized  Mortgage
     Loans;  or (B)  substantially  all the proceeds of such  Mortgage Loan were
     used to acquire,  improve or protect the real property  which served as the
     only  security  for such  Mortgage  Loan (other than a recourse  feature or
     other  third  party  credit  enhancement  within the  meaning  of  Treasury
     Regulations Section 1.860G-2(a)(1)(ii)).

          (xxxiv) LTV and  Significant  Modifications.  If the Mortgage Loan was
     "significantly  modified"  prior to the  Closing  Date so as to result in a
     taxable exchange under Section 1001 of the Code, it either (A) was modified
     as a result  of the  default  or  reasonably  foreseeable  default  of such
     Mortgage Loan or (B)  satisfies  the  provisions of either clause (A)(1) of
     paragraph (xxxiii) (substituting the date of the last such modification for
     the date the Mortgage  Loan was  originated)  or clause (A)(2) of paragraph
     (xxxiii), including the proviso thereto.

          (xxxv)  Credit Lease Loans.  With respect to Loan Number GMAC 4750 and
     Loan Number GMAC 1520 only, which are Credit Lease Loans:

          (A)  To the Seller's  knowledge,  each credit lease  ("Credit  Lease")
               contains  customary and enforceable  provisions  which render the
               rights and  remedies of the lessor  thereunder  adequate  for the
               enforcement and satisfaction of the lessor's rights thereunder;

          (B)  To the  Seller's  knowledge,  in  reliance  on a tenant  estoppel
               certificate  and  representation  made by the  tenant  under  the
               Credit  Lease or  representations  made by the  related  borrower
               under the Mortgage Loan Documents, as of the closing date of each
               Credit  Lease  Loan (1) each  Credit  Lease was in full force and
               effect, and no default by the borrower or the tenant has occurred
               under  the  Credit  Lease,  nor is there any  existing  condition
               which,  but for the  passage of time or the giving of notice,  or
               both,  would  result in a default  under the terms of the  Credit
               Lease,  (2)  none of the  terms of the  Credit  Lease  have  been
               impaired,  waived,  altered or modified in any respect (except as
               described in the related tenant estoppel), (3) no tenant has been
               released,  in whole or in part,  from its  obligations  under the
               Credit  Leases,  (4)  there is no right  of  rescission,  offset,
               abatement,  diminution,  defense  or  counterclaim  to any Credit
               Lease,  nor will the  operation of any of the terms of the Credit
               Leases,  or the  exercise  of any rights  thereunder,  render the
               Credit Lease  unenforceable,  in whole or in part,  or subject to
               any right of rescission,  offset, abatement,  diminution, defense
               or  counterclaim,  and  no  such  right  of  rescission,  offset,
               abatement,  diminution, defense or counterclaim has been asserted
               with respect thereto, and (5) each Credit Lease has a term ending
               on or after the final maturity of the related Credit Lease Loan;

          (C)  The Mortgaged Property is not subject to any lease other than the
               related Credit Lease,  no Person has any possessory  interest in,
               or right to  occupy,  the  Mortgaged  Property  except  under and
               pursuant  to such Credit  Lease and the tenant  under the related
               Credit Lease is in occupancy of the Mortgaged Property;

          (D)  The lease  payments under the related Credit Lease are sufficient
               to pay the entire  amount of scheduled  interest and principal on
               the  Credit  Lease  Loan,  subject to the rights of the Tenant to
               terminate the Credit Lease or offset, abate, suspend or otherwise
               diminish  any  amounts  payable  by the  tenant  under the Credit
               Lease.  Each Credit Lease Loan fully  amortizes over its original
               term,  and,  there is no "balloon"  payment of rent due under the
               Credit Leases;

          (E)  Under the terms of the Credit Leases, the lessee is not permitted
               to assign its  interest  or  obligations  under the Credit  Lease
               unless such lessee remains fully liable thereunder;


                                      C-7
<PAGE>


          (F)  The  mortgagee is entitled to notice of any event of default from
               the tenant under Credit Leases;

          (G)  Each tenant  under a Credit  Lease is required to make all rental
               payments  directly to the  mortgagee,  its successors and assigns
               under the related Credit Lease Loan;

          (H)  Each Credit  Lease Loan  provides  that the related  Credit Lease
               cannot be modified  without the consent of the  mortgagees  under
               the related Credit Lease Loan; and

          (I)  Each  Credit  Lease  Loan  under  which  a  Credit  Lease  may be
               terminated  upon the  occurrence  of a casualty  or  condemnation
               requires upon such  termination the payment in full by the tenant
               of: (a) the principal balance of the loan and (b) all accrued and
               unpaid interest on the Mortgage Loan.  Under the Credit Lease for
               each Credit  Lease  Loan,  upon the  occurrence  of a casualty or
               condemnation, the tenant has no right of rent abatement.

          (xxxvi)  Litigation.  To the Seller's actual  knowledge,  there are no
     pending   actions,   suits  or  proceedings  by  or  before  any  court  or
     governmental  authority  against or affecting the related  Mortgagor or the
     related Mortgaged Property that, if determined  adversely to such Mortgagor
     or Mortgaged  Property,  would materially and adversely affect the value of
     the Mortgaged  Property or the ability of the  Mortgagor to pay  principal,
     interest or any other amounts due under such Mortgage Loan.

          (xxxvii)  Leasehold  Estate.  Each Mortgaged  Property consists of the
     related  Mortgagor's  fee simple  interest  in real  estate or the  related
     Mortgage  Loan is  secured  in  whole  or in part  by the  interest  of the
     Mortgagor  as a lessee under a ground  lease of the  Mortgaged  Property (a
     "Ground  Lease").  Any Mortgage Loan that is secured by the interest of the
     Mortgagor under a Ground Lease may or may not be secured by the related fee
     interest in such  Mortgaged  Property (the "Fee  Interest").  If a Mortgage
     Loan is  secured  in  whole or in part by a Ground  Lease,  either  (1) the
     ground lessor's Fee Interest is subordinated to the lien of the Mortgage or
     (2) the following apply to such Ground Lease:

          (A)  To the actual  knowledge  of the Seller,  based on due  diligence
               customarily  performed in the origination of comparable  mortgage
               loans by the Seller,  such Ground Lease or a  memorandum  thereof
               has been or will be duly  recorded;  such  Ground  Lease  (or the
               related estoppel letter or lender  protection  agreement  between
               the Seller and related lessor) permits the interest of the lessee
               thereunder to be encumbered  by the related  Mortgage;  and there
               has been no material  change in the payment  terms of such Ground
               Lease since the  origination of the related  Mortgage Loan,  with
               the   exception   of  material   changes   reflected  in  written
               instruments that are a part of the related Mortgage File;


                                      C-8
<PAGE>


          (B)  The lessee's  interest in such Ground Lease is not subject to any
               liens or encumbrances superior to, or of equal priority with, the
               related  Mortgage,  other than the ground  lessor's  related  fee
               interest and Permitted Encumbrances;

          (C)  The  Mortgagor's  interest in such Ground Lease is  assignable to
               the Purchaser and its  successors and assigns upon notice to, but
               without  the  consent  of, the  lessor  thereunder  (or,  if such
               consent is required,  it has been  obtained  prior to the Closing
               Date)  and,  in the  event  that it is so  assigned,  is  further
               assignable by the Purchaser and its  successors  and assigns upon
               notice to, but  without  the need to obtain the  consent of, such
               lessor;

          (D)  Such Ground Lease is in full force and effect, and the Seller has
               received  no  notice  that  an  event  of  default  has  occurred
               thereunder,  and, to the Seller's actual knowledge,  there exists
               no condition  that,  but for the passage of time or the giving of
               notice,  or both,  would result in an event of default  under the
               terms of such Ground Lease;

          (E)  Such  Ground  Lease,  or an estoppel  letter or other  agreement,
               requires the lessor under such Ground Lease to give notice of any
               default by the lessee to the mortgagee  under such Mortgage Loan,
               provided  that the  mortgagee has provided the lessor with notice
               of its lien in  accordance  with the  provisions  of such  Ground
               Lease,  and such Ground  Lease,  or an  estoppel  letter or other
               agreement,  further provides that no notice of termination  given
               under such Ground Lease is effective against the mortgagee unless
               a copy has been delivered to the mortgagee;

          (F)  The mortgagee  under such Mortgage Loan is permitted a reasonable
               opportunity (including, where necessary,  sufficient time to gain
               possession of the interest of the lessee under such Ground Lease)
               to cure any  default  under such Ground  Lease,  which is curable
               after  the  receipt  of notice of any such  default,  before  the
               lessor thereunder may terminate such Ground Lease;

          (G)  Such Ground Lease has an original term  (including  any extension
               options set forth  therein) which extends not less than ten years
               beyond the Stated Maturity Date of the related Mortgage Loan;

          (H)  Under the terms of such Ground  Lease and the  related  Mortgage,
               taken  together,  any related  insurance  proceeds  other than in
               respect of a total or substantially total loss or taking, will be
               applied either to the repair or restoration of all or part of the
               related  Mortgaged  Property,   with  the  mortgagee  under  such
               Mortgage  Loan or a trustee  appointed  by it having the right to
               hold and  disburse  such  proceeds  as the repair or  restoration
               progresses  (except in such  cases  where a  provision  entitling
               another  party to hold and disburse  such  proceeds  would not be
               viewed  as  commercially  


                                      C-9
<PAGE>


               unreasonable by a prudent commercial  mortgage lender), or to the
               payment of the outstanding principal balance of the Mortgage Loan
               together with any accrued interest thereon;

          (I)  Such Ground Lease does not impose any  restrictions on subletting
               which  would  be  viewed,  as of the date of  origination  of the
               related  Mortgage  Loan,  as  commercially  unreasonable  by  the
               Seller; and such Ground Lease contains a covenant that the lessor
               thereunder  is  not  permitted,  in  the  absence  of an  uncured
               default,  to disturb the possession,  interest or quiet enjoyment
               of any  subtenant  of the lessee,  or in any manner,  which would
               materially  adversely affect the security provided by the related
               Mortgage; and

          (J)  Such  Ground  Lease,  or an estoppel  letter or other  agreement,
               requires  the  lessor to enter into a new lease in the event of a
               termination  of the  Ground  Lease by reason of a default  by the
               Mortgagor  under the Ground  Lease,  including,  rejection of the
               ground lease in a bankruptcy proceeding.

          (xxxviii)Deed  of Trust. If the related Mortgage is a deed of trust, a
     trustee,  duly qualified under applicable law to serve as such, is properly
     designated and serving under such Mortgage.

          (xxxix) Lien Releases. Except in cases where either (a) a release of a
     portion of the Mortgaged  Property was  contemplated  at origination of the
     Mortgage Loan and such portion was not considered  material for purposes of
     underwriting  the  Mortgage  Loan or (b)  release is  conditioned  upon the
     satisfaction of certain underwriting and legal requirements and the payment
     of a release price,  the related Mortgage Note or Mortgage does not require
     the holder thereof to release all or any portion of the Mortgaged  Property
     from the lien of the related  Mortgage  except upon  payment in full of all
     amounts due under such Mortgage Loan.

          (xl)  Junior  Liens.  The  Mortgage  Loan does not permit the  related
     Mortgaged  Property  to be  encumbered  by any lien  junior  to or of equal
     priority with the lien of the related Mortgage (excluding any lien relating
     to another  Mortgage Loan that is  cross-collateralized  with such Mortgage
     Loan)  without  the prior  written  consent  of the  holder  thereof or the
     satisfaction  of debt  service  coverage  or similar  conditions  specified
     therein.

          (xli) Mortgagor Bankruptcy.  To the Seller's knowledge,  the Mortgagor
     is  not  a  debtor  in  any  state  or  federal  bankruptcy  or  insolvency
     proceeding.

          (xlii) Due  Organization of Mortgagors.  As of the date of origination
     of each Mortgage,  each related Mortgagor which is not a natural person was
     duly  organized  and  validly  existing  under the laws of the state of its
     jurisdiction. 

          (xliii)  Due-On-Sale.  The Mortgage Loan contains  provisions  for the
     acceleration  of the  payment  of the  unpaid  principal  balance  of  such
     Mortgage Loan if, without  complying with the requirements of such Mortgage
     Loan, the related Mortgaged Property,  or any controlling interest therein,
     is directly or indirectly transferred or sold.



                                      C-10

          (xliv)  Single  Purpose  Entity.  The related  Mortgagor is an entity,
     other than an  individual,  whose  organizational  documents or the related
     Mortgage  Loan  Documents  provide  substantially  to the  effect  that the
     Mortgagor:  (A) is formed or organized solely for the purpose of owning and
     operating  one or more of the  Mortgaged  Properties  securing the Mortgage
     Loans,  (B) may not  engage in any  business  unrelated  to such  Mortgaged
     Property or Mortgaged  Properties,  (C) does not have any  material  assets

     has its own books and records separate and apart from any other person, and
     (F) holds itself out as a legal  entity,  separate and apart from any other
     person.

          (xlv)  Defeasance  Provisions.  Any  Mortgage  Loan  which  contains a
     provision for any defeasance of mortgage collateral either (A) requires the
     consent  of the  holder  of the  Mortgage  Loan to any  defeasance,  or (B)
     permits defeasance (i) no earlier than two years after the Closing Date (as
     defined in the Pooling  and  Servicing  Agreement,  dated as of February 1,
     1999),  (ii)  only  with  substitute  collateral  constituting  "government
     securities"  within the meaning of Treas. Reg. ss.  1.860G-2(a)(8)(i),  and
     (iii) only to facilitate the  disposition of mortgage real property and not
     as a  part  of an  arrangement  to  collateralize  a  REMIC  offering  with
     obligations that are not real estate mortgages.

          (xlvi) Nursing Home or Congregate Care Facility.

          (A) to the Seller's  knowledge,  based upon due diligence  customarily
     performed in the origination of comparable mortgage loans as of the date of
     the  origination  of the  Mortgage  Loan,  the  operator of the  healthcare
     facility  located  on the  related  Mortgaged  Property  had  all  material
     licenses and permits  required by applicable  law for the operation and use
     of such facility;

          (B) to the Seller's  knowledge,  based upon due diligence  customarily
     performed in the origination of comparable mortgage loans as of the date of
     the  origination  of the Mortgage  Loan,  to the extent that such  facility
     participates  in Medicaid,  Medicare,  or any other  similar  program,  the
     facility is in  compliance in all material  respects with the  requirements
     for participation in such programs;

                   FORM OF OPINION I OF COUNSEL TO THE SELLER

February ___, 1999

To:  Persons on Annex A

Re:  GMAC Commercial Mortgage Securities, Inc.
     Mortgage Pass-Through Certificates, Series 1999-C1

Ladies and Gentlemen:

     I am General Counsel to GMAC Commercial Mortgage  Corporation (the "Seller"
or  "GMACCM").  In that  capacity,  I am familiar  with the  issuance of certain
Mortgage  Pass-Through   Certificates,   Series  1999-C1  (the  "Certificates"),
evidencing  undivided  interests in a trust fund (the "Trust  Fund")  consisting
primarily  of certain  mortgage  loans (the  "Mortgage  Loans"),  pursuant  to a
Pooling and Servicing Agreement,  dated as of February 1, 1999 (the "Pooling and
Servicing  Agreement"),  among GMAC Commercial  Mortgage  Securities,  Inc. (the
"Company") as  depositor,  the Seller as master  servicer and special  servicer,
Norwest Bank Minnesota, National Association, as trustee (the "Trustee").

     Certain  of the  Mortgage  Loans were  purchased  by the  Company  from the
Seller,  pursuant to, and for the consideration  described in, the Mortgage Loan
Purchase  Agreement,  dated as of February 2, 1999 (the  "GMACCM  Mortgage  Loan
Purchase  Agreement"),  between  the  Company  and the  Seller.  Certain  of the
Mortgage  Loans will be purchased by the Company from LaSalle  National  Bank as
Trustee for  Restructured  Asset  Certificates  With  Enhanced  Returns,  Series
1998-ML Trust ("ML Trust") pursuant to, and for the consideration  described in,
the  Mortgage  Loan  Purchase  Agreement,  dated as of February 2, 1999 (the "ML
Trust Mortgage Loan Purchase  Agreement")  between the Company and the ML Trust.
Certain of the  Mortgage  Loans will be  purchased  by the  Company  from German
American Capital  Corporation  ("GACC"),  pursuant to, and for the consideration
described in, the Mortgage Loan Purchase Agreement, dated as of February 2, 1999
(the "GACC Mortgage Loan Purchase  Agreement"),  between the Depositor and GACC.
The  Pooling and  Servicing  Agreement  and the GMACCM  Mortgage  Loan  Purchase
Agreement are referred to herein together as the "Agreements." Capitalized terms
not defined herein have the meanings set forth in the  Agreements.  This opinion
is  rendered  pursuant  to Section  8(e) of the GMACCM  Mortgage  Loan  Purchase
Agreement.

     The Company has sold the Class A-1,  Class A-2,  Class B, Class C, Class D,
and Class E and a portion of the Class X Certificates  to Goldman,  Sachs & Co.,
Deutsche  Bank  Securities  Inc.  and  Donaldson,  Lufkin & Jenrette  Securities
Corporation as the underwriters (the  "Underwriters")  named in the Underwriting
Agreement,  dated as of February 2, 1999 (the "Underwriting  Agreement"),  among
the Company, the Seller, and the Underwriters. The Company has sold a portion of
the Class X Certificates  to GMACCM  pursuant to a Class X Certificate  Purchase
Agreement,  dated as of  February  2, 1999 (the  "Class X  Certificate  Purchase
Agreement"), between the Company and GMACCM. The Company sold the Class F, Class
G,  Class  H,  Class J and  Class  K  Certificates  to  GMACCM  pursuant  to the
Certificate  Purchase 



                                     D-3A-1
<PAGE>


Agreement,  dated as of February 2, 1999 (the "Certificate Purchase Agreement"),
between the Company and GMACCM.  The Company sold the Class R-I,  Class R-II and
Class R-III Certificates to Goldman, Sachs & Co.

     In connection with rendering this opinion  letter,  I have examined or have
caused  persons under my  supervision  to examine the  Agreements and such other
records and other documents as I have deemed  necessary.  I have further assumed
that  there  is not  and  will  not  be  any  other  agreement  that  materially
supplements or otherwise modifies the agreements expressed in the Agreements. As
to matters of fact, I have examined and relied upon  representations  of parties
contained   in  the   Agreements   and,   where  I  have   deemed   appropriate,
representations  and certifications of officers of the Company,  the Seller, the
Trustee, other transaction  participants or public officials. I have assumed the
authenticity of all documents  submitted to me as originals,  the genuineness of
all  signatures  other than  officers  of the Seller and the  conformity  to the
originals of all  documents  submitted to me as copies.  I have assumed that all
parties,  except for the  Company and the Seller,  had the  corporate  power and
authority  to enter into and  perform  all  obligations  thereunder.  As to such
parties,  I also have assumed the due  authorization by all requisite  corporate
action, the due execution and delivery and the enforceability of such documents.
I have  further  assumed  the  conformity  of the  Mortgage  Loans  and  related
documents to the requirements of the Agreements.

     In rendering this opinion letter,  I do not express any opinion  concerning
any law other than the law of the  Commonwealth  of  Pennsylvania,  the  General
Corporation  Law of the State of  Delaware  and the  federal  law of the  United
States,  and I do not express  any opinion  concerning  the  application  of the
"doing business" laws or the securities laws of any jurisdiction  other than the
federal  securities  laws of the United  States.  To the extent  that any of the
matters upon which I am opining herein are governed by laws ("Other Laws") other
than the laws  identified  in the preceding  sentence,  I have assumed with your
permission  and without  independent  verification  or  investigation  as to the
reasonableness   of  such   assumption,   that  such  Other  Laws  and  judicial
interpretation  thereof do not vary in any respect material to this opinion from
the  corresponding  laws  of  the  Commonwealth  of  Pennsylvania  and  judicial
interpretations thereof. I do not express any opinion on any issue not expressly
addressed below.

     Based upon the foregoing, I am of the opinion that:

1.   Each of the Agreements has been duly and validly  authorized,  executed and
     delivered by the Seller and, upon due authorization, execution and delivery
     by the other parties thereto,  will constitute the valid, legal and binding
     agreements of the Seller, enforceable against the Seller in accordance with
     their terms,  except as  enforceability  may be limited by (i)  bankruptcy,
     insolvency, liquidation,  receivership, moratorium, reorganization or other
     similar laws affecting the rights of creditors,  (ii) general principles of
     equity,  whether enforcement is sought in a proceeding in equity or at law,
     and (iii) public policy  considerations  underlying the securities laws, to
     the extent that such public policy  considerations limit the enforceability
     of  the   provisions   of  the   Agreements   which   purport   to  provide
     indemnification with respect to securities law violations.

2.   No  consent,  approval,   authorization  or  order  of  a  Commonwealth  of
     Pennsylvania  or federal court or  governmental  agency or body is required
     for the consummation by the 



                                     D-3A-2
<PAGE>


     Seller of the  transactions  contemplated  by the terms of the  Agreements,
     except  for those  consents,  approvals,  authorizations  or  orders  which
     previously have been obtained.

3.   Neither the  consummation of any of the  transactions  contemplated by, nor
     the fulfillment by the Seller of any other of the terms of, the Agreements,
     will result in a material breach of any term or provision of the charter or
     bylaws of the Seller or any Commonwealth of Pennsylvania or federal statute
     or regulation or conflict with,  result in a material breach,  violation or
     acceleration  of or  constitute a material  default  under the terms of any
     indenture or other material  agreement or instrument to which the Seller is
     a  party  or by  which  it is  bound  or any  order  or  regulation  of any
     Commonwealth   of   Pennsylvania   or  federal  court,   regulatory   body,
     administrative  agency or governmental  body having  jurisdiction  over the
     Seller.

This opinion letter is rendered for the sole benefit of each  addressee  hereof,
and no other person or entity,  except  Orrick,  Herrington & Sutcliffe  LLP, is
entitled to rely hereon  without prior written  consent.  Copies of this opinion
letter may not be furnished  to any other person or entity,  nor may any portion
of this  opinion  letter  be  quoted,  circulated  or  referred  to in any other
document without my prior written consent.

                                           Very truly yours,

                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of February 2, 1999, between German American Capital Corporation as
seller (the "Seller") and GMAC Commercial Mortgage Securities, Inc. as purchaser
(the "Purchaser").

     The Seller desires to sell,  assign,  transfer and otherwise  convey to the
Purchaser,  and the  Purchaser  desires  to  purchase,  subject to the terms and
conditions set forth below,  the multifamily and commercial  mortgage loans (the
"Mortgage  Loans")  identified on the schedule  annexed hereto as Exhibit A (the
"Mortgage Loan Schedule").

     It is expected that the Mortgage Loans will be  transferred,  together with
other  multifamily  and  commercial  mortgage  loans to a trust fund (the "Trust
Fund") to be formed by the  Purchaser,  beneficial  ownership  of which  will be
evidenced   by   a   series   of   mortgage   pass-through   certificates   (the
"Certificates"). Certain classes of the Certificates will be rated by Standard &
Poor's Ratings Services and Fitch IBCA Inc.  (together,  the "Rating Agencies").
Certain classes of the  Certificates  (the  "Registered  Certificates")  will be
registered under the Securities Act of 1933, as amended (the "Securities  Act").
The Trust Fund will be created and the Certificates will be issued pursuant to a
pooling and servicing agreement to be dated as of February 1, 1999 (the "Pooling
and Servicing  Agreement"),  among the Purchaser as depositor,  GMAC  Commercial
Mortgage  Corporation  as  master  servicer  (in  such  capacity,   the  "Master
Servicer") and special servicer (in such capacity,  the "Special  Servicer") and
Norwest Bank Minnesota,  National Association, as trustee (in such capacity, the
"Trustee").  Capitalized  terms not otherwise  defined  herein have the meanings
assigned  to them in the  Pooling and  Servicing  Agreement  as in effect on the
Closing Date.

     The Purchaser  intends to sell the Class A-1,  Class A-2, Class B, Class C,
Class D, Class E and a portion of the Class X Certificates  to Goldman,  Sachs &
Co., Deutsche Bank Securities Inc. and Donaldson,  Lufkin & Jenrette  Securities
Corporation (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  The Purchaser intends to
sell a portion of the Class X Certificates to GMACCM (in such capacity, a "Class
X Certificate  Purchaser")  pursuant to a Class X Certificate Purchase Agreement
dated the date  hereof  (the  "Class X  Certificate  Purchase  Agreement").  The
Purchaser  intends  to sell the Class F,  Class G,  Class H, Class J and Class K
Certificates to GMACCM (in such capacity,  an "Initial Purchaser") pursuant to a
Certificate Purchase Agreement dated the date hereof (the "Certificate  Purchase
Agreement").  The  Purchaser  intends to sell the Class R-I,  Class R-II and the
Class R-III Certificates to Goldman,  Sachs & Co. (in such capacity, an "Initial
Purchaser").  The Class F, Class G, Class H, Class J, Class K, Class R-I,  Class
R-II  and  Class  R-III  Certificates  are  collectively   referred  to  as  the
"Non-Registered Certificates."

     Now, therefore,  in consideration of the premises and the mutual agreements
set forth herein, the parties agree as follows:


<PAGE>


     Section 1. Agreement to Purchase.

     The Seller agrees to sell,  assign,  transfer and  otherwise  convey to the
Purchaser,  and the  Purchaser  agrees to  purchase,  the  Mortgage  Loans.  The
purchase and sale of the Mortgage  Loans shall take place on February 2, 1999 or
such other date as shall be  mutually  acceptable  to the  parties  hereto  (the
"Closing Date"). The "Cut-off Date" with respect to any Mortgage Loan is the Due
Date for such  Mortgage  Loan in February  1999.  As of the close of business on
their  respective  Cut-off Dates (which Cut-off Date may occur after the Closing
Date),  the  Mortgage  Loans  will  have an  aggregate  principal  balance  (the
"Aggregate  Cut-off  Date  Balance"),  after  application  of  all  payments  of
principal  due  thereon on or before  such date,  whether  or not  received,  of
$5,356,279,  subject to a variance of plus or minus 5%. The  purchase  price for
the  Mortgage  Loans shall be  determined  pursuant to a certain  Mortgage  Loan
Purchase Agreement, dated as of March 31, 1998.

     Section 2. Conveyance of Mortgage Loans.

     (a) Effective as of the Closing Date, subject only to receipt by the Seller
of the  purchase  price  referred  to in  Section  1  hereof  (exclusive  of any
applicable  holdback  for  transaction  expenses),  the Seller does hereby sell,
transfer,  assign,  set over and  otherwise  convey  to the  Purchaser,  without
recourse, all the right, title and interest of the Seller in and to the Mortgage
Loans  identified on the Mortgage  Loan Schedule as of such date,  including all
interest and  principal  received or receivable by the Seller on or with respect
to the Mortgage  Loans after the Cut-off Date for such Mortgage  Loan,  together
with all of the Seller's right, title and interest in and to the proceeds of any
related title,  hazard, or other insurance  policies and any escrow,  reserve or
other comparable  accounts related to the Mortgage Loans. The Purchaser shall be

Seller  shall  deliver or cause to be  delivered  to or at the  direction of the
Purchaser) all scheduled  payments of principal and interest due on the Mortgage

     (c) All  documents  and records in the  Seller's  possession  (or under its

(or its agent) to the  Purchaser  (or its  designee)  no later than the  Closing
Date. If a sub-servicer shall, as of the Closing Date, begin acting on behalf of
the Master  Servicer  with  respect to any Mortgage  Loan  pursuant to a written
agreement  between such parties,  the Seller shall deliver a copy of the related
Servicing File to the Master Servicer.

     (d) The Seller's records will reflect the transfer of the Mortgage Loans to

     The Seller shall reasonably  cooperate with any examination of the Mortgage
Files  and  Servicing  Files  that  may be  undertaken  by or on  behalf  of the
Purchaser.  The fact that the  Purchaser  has conducted or has failed to conduct
any partial or complete examination of the Mortgage Files and/or Servicing Files
shall not affect the Purchaser's  right to pursue any remedy available in equity
or at law for a breach of the Seller's representations, warranties and covenants
set forth in or contemplated by Section 4.

Section 4. Representations, Warranties and Covenants of the Seller.

     (a) Reserved.

     in good  standing  under  the  laws of the  State  of  Maryland,  and is in
     compliance  with the laws of each State to the extent  necessary to perform
     its obligations under this Agreement.

          (ii) The execution and delivery of this  Agreement by the Seller,  and
     the  performance  and  compliance  with the terms of this  Agreement by the
     Seller,  will  not  violate  the  Seller's   organizational   documents  or
     constitute a default (or an event which,  with notice or lapse of time,  or
     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets,  in each case which  materially  and
     adversely  affect the  ability of the Seller to carry out the  transactions
     contemplated by this Agreement.

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery  by  the  Purchaser,   constitutes  a  valid,  legal  and  binding
     obligation of the Seller, enforceable against the Seller in accordance with
     the  terms  hereof,  subject  to  (A)  applicable  bankruptcy,  insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors' rights generally,  (B) general principles of equity,  regardless
     of whether such  enforcement  is considered in a proceeding in equity or at
     law, and (C)

     public policy considerations  underlying the securities laws, to the extent
     that such public  policy  considerations  limit the  enforceability  of the
     provisions of this  Agreement that purport to provide  indemnification  for
     securities laws liabilities.

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

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

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  the
     Class X Certificate Purchaser, the Initial Purchasers, and their respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with  the  sale of the  Mortgage  Loans  by the  Seller  to the
     Purchaser or the consummation of any of the other transactions contemplated
     hereby.

          (viii)  Neither  the Seller  nor  anyone  acting on its behalf has (A)
     offered,   pledged,   sold,  disposed  of  or  otherwise   transferred  any
     Certificate,  any interest in any Certificate or any other similar security
     to any person in any manner,  (B) solicited any offer to buy or to accept a
     pledge,  disposition or other transfer of any Certificate,  any interest in
     any  Certificate  or any  other  similar  security  from any  person in any
     manner,  (C)  otherwise  approached  or  negotiated  with  respect  to  any
     Certificate,  any interest in any Certificate or any other similar security
     with any person in any manner,  (D) made any general  solicitation by means
     of  general  advertising  or in  any  other  manner  with  respect  to  any
     Certificate,  any interest in any Certificate or any similar  security,  or
     (E) taken any other action,  that (in the case of any of the acts described
     in clauses (A) through (E) above) would constitute or result in a violation
     of the  Securities  Act or  any  state  securities  law  relating  to or in
     connection with the issuance of the Certificates or require registration or
     qualification pursuant to the Securities Act or any state securities law of
     any Certificate not otherwise intended to be a Registered  Certificate.  In
     addition,  the  Seller  will  not  act,  nor has it  authorized  or will it
     authorize  any  person to act,  in any  manner  set forth in the  foregoing
     sentence with respect to any of the Certificates or interests therein.  For
     purposes of this paragraph 4(b)(viii), the term "similar security" shall be
     deemed to include,  without  limitation,  any security  evidencing or, upon
     issuance,  that would have  evidenced an interest in the Mortgage  Loans or
     any substantial number thereof.

          (ix) No consent, approval,  authorization or order of, registration or
     filing with, or notice to, any governmental authority or court is required,
     under federal or state law (including, with respect to any bulk sale laws),
     for the execution, delivery and

     consummation by the Seller of any transaction  contemplated  hereby,  other
     than (1) the filing or recording of financing  statements,  instruments  of
     assignment  and  other  similar  documents  necessary  in  connection  with
     Seller's sale of the Mortgage  Loans to the  Purchaser,  (2) such consents,
     approvals,  authorizations,   qualifications,   registrations,  filings  or
     notices  as have  been  obtained  or made  and (3)  where  the lack of such
     consent, approval,  authorization,  qualification,  registration, filing or
     notice would not have a material  adverse effect on the  performance by the
     Seller under this Agreement.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)
above which materially and adversely affects the interests of the Purchaser, the
party  discovering  such breach  shall give prompt  written  notice to the other
party hereto.

     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets.

          (iii) The Purchaser has the full power and authority to enter into and

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

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

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

     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the transactions contemplated hereby.

     or filing  with,  or notice  to,  any  governmental  authority  or court is
     required,  under  federal or state law,  for the  execution,  delivery  and

representations  and warranties  set forth above which  materially and adversely
affects the  interests of the Seller,  the party  discovering  such breach shall

Re:   GMAC Commercial Mortgage Securities, Inc.,
      Mortgage Pass-Through Certificates, Series 1999-C1

Ladies and Gentlemen:

     I am  Director  and Counsel to German  American  Capital  Corporation  (the
"Seller"). In that capacity, I am familiar with the issuance of certain Mortgage
Pass-Through  Certificates,  Series  1999-C1  (the  "Certificates"),  evidencing
undivided  interests in a trust fund (the "Trust Fund") consisting  primarily of
certain  mortgage  loans  (the  "Mortgage  Loans"),  pursuant  to a Pooling  and
Servicing  Agreement,  dated as of February 1, 1999 (the  "Pooling and Servicing
Agreement"),  among GMAC Commercial Mortgage Securities,  Inc. as depositor (the
"Depositor"), GMAC Commercial Mortgage Corporation ("GMACCM") as master servicer
and special  servicer  and Norwest  Bank  Minnesota,  National  Association,  as
trustee (the "Trustee").

     Certain of the Mortgage  Loans were  purchased by the Depositor from German
American Capital  Corporation  ("GACC"),  pursuant to, and for the consideration
described in, the Mortgage Loan Purchase Agreement, dated as of February 2, 1999
(the  "Agreement"),  between the  Depositor  and GACC.  In  connection  with the
transactions  described  above,  the  Seller  and  GMACCM  have  entered  into a
Supplemental  Agreement,  dated  as of  February  __,  1999  (the  "Supplemental
Agreement"),  in order to facilitate such  transactions  and in contemplation of
the assignment by the Purchaser to the Depositor of all of its right,  title and
interest in and to the GACC Mortgage Loan Purchase Agreement.  The Agreement and
the  Supplemental   Agreement  are  referred  to  herein  as  the  "Agreements."
Capitalized  terms  not  defined  herein  have  the  meanings  set  forth in the
Agreement. This opinion is rendered pursuant to Section 8(e) of the Agreement.



                                      C-3-1
<PAGE>


     In connection with rendering this opinion  letter,  I have examined or have
caused  persons under my  supervision  to examine the  Agreements and such other
records and other documents as I have deemed  necessary.  I have further assumed
that  there  is not  and  will  not  be  any  other  agreement  that  materially
supplements or otherwise modifies the agreements expressed in the Agreements. As
to matters of fact, I have examined and relied upon  representations  of parties
contained   in  the   Agreements   and,   where  I  have   deemed   appropriate,
representations  and  certifications of officers of GMACCM,  the Depositor,  the
Seller, the Trustee, other transaction  participants or public officials. I have
assumed the  authenticity  of all documents  submitted to me as  originals,  the
genuineness  of all  signatures  other  than  officers  of the  Seller  and  the
conformity to the originals of all documents  submitted to me as copies.  I have
assumed that all parties,  except for the Seller,  had the  corporate  power and
authority  to enter into and  perform  all  obligations  thereunder.  As to such
parties,  I also have assumed the due  authorization by all requisite  corporate
action, the due execution and delivery and the enforceability of such documents.
I have  further  assumed  the  conformity  of the  Mortgage  Loans  and  related
documents to the requirements of the Agreements.

     In rendering this opinion letter,  I do not express any opinion  concerning
any law other than the law of the State of New York, the General Corporation Law
of the State of Delaware and the federal law of the United States,  and I do not
express any opinion  concerning the application of the "doing  business" laws or
the securities laws of any jurisdiction  other than the federal  securities laws
of the United  States.  To the extent  that any of the  matters  upon which I am
opining  herein  are  governed  by laws  ("Other  Laws")  other  than  the  laws
identified in the preceding  sentence,  I have assumed with your  permission and
without  independent  verification or investigation as to the  reasonableness of
such assumption, that such Other Laws and judicial interpretation thereof do not
vary in any respect material to this opinion from the corresponding  laws of the
State of New York and  judicial  interpretations  thereof.  I do not express any
opinion on any issue not expressly addressed below.

Based upon the foregoing, I am of the opinion that:

1.   The Seller is duly incorporated and is validly existing as a corporation in
     good standing under the laws of the State of Maryland and has the requisite
     power and authority,  corporate or other, to own its properties and conduct
     its business,  as presently  conducted by it, and to enter into and perform
     its obligations under the Agreements.

2.   The  Agreements  have  been  duly  and  validly  authorized,  executed  and
     delivered by the Seller and, upon due authorization, execution and delivery
     by the other parties thereto,  will constitute the valid, legal and binding
     agreements of the Seller enforceable  against the Seller in accordance with
     their terms,  except as  enforceability  may be limited by (i)  bankruptcy,
     insolvency, liquidation,  receivership, moratorium, reorganization or other
     similar laws affecting the rights of creditors,  (ii) general principles of
     equity,  whether enforcement is sought in a proceeding in equity or at law,
     and (iii) public policy  considerations  underlying the securities laws, to
     the extent that such public policy  considerations limit the enforceability
     of  the   provisions   of  the   Agreements   which   purport   to  provide
     indemnification with respect to securities law violations.


                                      C-3-2
<PAGE>


3.   Neither the  consummation of any of the  transactions  contemplated by, nor
     the fulfillment by the Seller of any other of the terms of, the Agreements,
     will result in a material breach of any term or provision of the charter or
     bylaws of the  Seller or any state or  federal  statute  or  regulation  or
     conflict with, result in a material breach, violation or acceleration of or
     constitute  a material  default  under the terms of any  indenture or other
     material agreement or instrument to which the Seller is a party or by which
     it is bound or any  order or  regulation  of any  state or  federal  court,

<PAGE>


                             SUPPLEMENTAL AGREEMENT


     This Supplemental  Agreement (this "Agreement"),  is dated and effective as
of February 2, 1999, between GMAC Commercial Mortgage Corporation as seller (the
"Seller")  and  German   American   Capital   Corporation   as  purchaser   (the
"Purchaser").

     WHEREAS, the Seller sold certain mortgage loans (the "GACC Mortgage Loans")
to the Purchaser  pursuant to a certain  Mortgage Loan Purchase  Agreement  (the
"GACC Purchase Agreement"), dated as of March 31, 1998.

     WHEREAS,  the Purchaser  intends to sell certain of the GACC Mortgage Loans

"Certificates"). Certain classes of the Certificates will be rated by Standard &
Poor's Ratings Services and Fitch IBCA, Inc. (together,  the "Rating Agencies").
Certain classes of the  Certificates  (the  "Registered  Certificates")  will be
registered under the Securities Act of 1933, as amended (the "Securities  Act").
The Trust Fund will be created and the Certificates will be issued pursuant to a

and Servicing  Agreement"),  among the Depositor as depositor,  GMAC  Commercial
Mortgage  Corporation  as  master  servicer  (in  such  capacity,   the  "Master

Securities   Corporation   (together,   the   "Underwriters")   pursuant  to  an
Underwriting   Agreement  dated  as  of  the  date  hereof  (the   "Underwriting
Agreement").  The Depositor  intends to sell a portion of the X Certificates  to
GMAC Commercial Mortgage Corporation ("GMACCM," and in such capacity, the "Class
X Certificate  Purchaser")  pursuant to a Class X Certificate Purchase Agreement
dated as of the date hereof (the "Class X Certificate Purchase Agreement").  The

     WHEREAS,  each of the  Seller and the  Purchaser,  in  connection  with the
transactions  described  above,  desires to amend and supplement  certain of the

<PAGE>


and in  contemplation of the assignment by the Purchaser to the Depositor of all
of its right, title and interest in and to this Agreement.

     Now, therefore,  in consideration of the premises and the mutual agreements
set forth herein, the parties agree as follows:

SECTION 1. Amendment of GACC Purchase Agreement.

     The parties hereto agree that, with respect to the Mortgage Loans only, the
GACC Purchase  Agreement is hereby  amended to the extent that the provisions of
the GACC Purchase Agreement are inconsistent with this Agreement.

SECTION 2. Representations, Warranties and Covenants of the Seller.

     (a) The Seller  hereby makes,  as of February 9, 1999 (the "Closing  Date")
(or as of such other date specifically provided in the particular representation
or warranty),  to and for the benefit of the  Purchaser,  and its successors and
assigns  (including,  without  limitation,  the  Depositor,  the Trustee and the
holders of the  Certificates),  each of the  representations  and warranties set
forth in Exhibit B, with such  changes or  modifications  as may be permitted or
required by the Rating Agencies.

     (b) In addition,  the Seller, as of the date hereof,  hereby represents and
warrants to, and covenants with, the Purchaser that:

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

          (ii) The execution and delivery of this  Agreement by the Seller,  and
     the  performance  and  compliance  with the terms of this  Agreement by the
     Seller,  will  not  violate  the  Seller's   organizational   documents  or
     constitute a default (or an event which,  with notice or lapse of time,  or
     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets,  in each case which  materially  and
     adversely  affect the  ability of the Seller to carry out the  transactions
     contemplated by this Agreement.

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery  by  the  Purchaser,   constitutes  a  valid,  legal  and  binding
     obligation of the Seller, enforceable against the Seller in accordance with
     the  terms  hereof,  subject  to  (A)  applicable  bankruptcy,  insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors' rights generally,  (B) general principles of equity,  regardless
     of


                                       2
<PAGE>


     whether such enforcement is considered in a proceeding in equity or at law,
     and (C) public policy considerations underlying the securities laws, to the
     extent that such public policy  considerations  limit the enforceability of
     the provisions of this  Agreement  that purport to provide  indemnification
     for securities laws liabilities.

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

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

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  the
     Class X Certificate Purchaser,  the Initial Purchasers and their respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the other transactions contemplated hereby.

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

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)
above which  materially and adversely  affects the interests of the Purchaser or
its  successors  or  assigns  or a  breach  of any of  the  representations  and
warranties  made  pursuant  to  subsection  (a) above and set forth in Exhibit B
which  materially  and  adversely  affects the value of any Mortgage Loan or the
interests  therein of the Purchaser or its  successors  and assigns  (including,
without   limitation  the  Depositor,   the  Trustee  and  the  holders  of  the
Certificates),  the party  discovering  such breach  shall give  prompt  written
notice to the other party hereto or if this Agreement has been assigned, to such
assignee.  The  representations,  warranties  and  covenants  set  forth in this
Section 2(a) shall, as between Seller and Purchaser,  supplement, and as between
Seller and any successors or assigns of Purchaser, replace and amend and restate
in their entirety the representations,


                                       3
<PAGE>


warranties  and covenants of the Seller set forth in Section  4.1(a) of the GACC
Purchase Agreement to the extent they relate to the Mortgage Loans.

SECTION 3. Representations, Warranties and Covenants of the Purchaser.

     (a) The Purchaser,  as of the date hereof,  hereby  represents and warrants
to, and covenants with, the Seller that:

          (i) The Purchaser is a corporation  duly organized,  validly  existing
     and in good standing under the laws of State of Maryland.

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

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery by the Seller,  constitutes a valid,  legal and binding obligation
     of the Purchaser,  enforceable against the Purchaser in accordance with the
     terms   hereof,   subject  to  (A)   applicable   bankruptcy,   insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors'  rights  generally,   and  (B)  general  principles  of  equity,
     regardless  of whether such  enforcement  is  considered in a proceeding in
     equity or at law.

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

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

          (vii) The Purchaser has not dealt with any broker,  investment banker,
     agent or other person, other than the Seller, the Underwriters, the Class X
     Certificate   Purchaser,   the  Initial  Purchasers  and  their  respective
     affiliates, that may be entitled to any


                                       4
<PAGE>


     commission  or  compensation  in  connection  with the sale of the Mortgage
     Loans or the consummation of any of the transactions contemplated hereby.

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

     (b) The Purchaser hereby makes, as of the Closing Date (or as of such other
date specifically provided in the particular representation or warranty), to and
for the benefit of the Seller,  and its successors and assigns,  with respect to
each Mortgage Loan each of the representations and warranties set forth below:

          (i) Immediately  prior to the transfer  thereof to the Depositor,  the
     Purchaser had whatever title to such Mortgage Loan as was conveyed to it by
     Seller,  free  and  clear  of any and all  liens,  encumbrances  and  other
     interests on, in or to such  Mortgage  Loan (other than, in certain  cases,
     the right of a subservicer to directly  service such Mortgage Loan) created
     by  Purchaser.  Such transfer  validly  assigns such title to such Mortgage
     Loan to the Depositor  free and clear of any pledge,  lien,  encumbrance or
     security interest created by the Purchaser.

          (ii) Without  independent inquiry as to the provisions of the Mortgage
     Loans,  the  Purchaser  has full right and  authority  to sell,  assign and
     transfer its interest in such Mortgage Loan.

          (iii) The  Purchaser  has not, by act or omission,  done anything that
     would  materially  impair the coverage under the lender's  title  insurance
     policy that insures the lien of the related Mortgage.

          (iv) The  Purchaser  has not  waived  any  material  default,  breach,
     violation or event of acceleration  existing under the related  Mortgage or
     Mortgage Note.

          (v) To the  best of the  Purchaser's  knowledge,  without  independent
     inquiry  as to the  provisions  of the  Mortgage  Loans,  there is no valid
     offset, defense or counterclaim to such Mortgage Loan.

          (vi) The terms of the related  Mortgage and the Mortgage Note have not
     been impaired, waived, altered or modified by the Purchaser in any material
     respect, except as specifically set forth in the related Mortgage File.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties  set forth above which  materially and adversely
affects the


                                       5
<PAGE>


interests  of the Seller,  the party  discovering  such breach shall give prompt
written notice to the other party hereto.

SECTION 4. Repurchases.

     (a) Within 90 days of the earlier of  discovery or receipt of notice by the
Seller,  from either the  Purchaser  or any  successor or assign  thereof,  of a
Defect (as defined in the Pooling and  Servicing  Agreement  as in effect on the
Closing  Date) in respect of the Mortgage File for any Mortgage Loan or a breach
of any representation or warranty made pursuant to Section 2(a) and set forth in
Exhibit B (a "Breach"),  which Defect or Breach,  as the case may be, materially
and adversely affects the value of any Mortgage Loan or the interests therein of
the Purchaser or its successors and assigns (including,  without limitation, the
Depositor,  the Trustee and the holders of the  Certificates),  the Seller shall
cure such  Defect or Breach,  as the case may be, in all  material  respects  or
repurchase  the affected  Mortgage  Loan from the then  owner(s)  thereof at the
applicable  Purchase Price (as defined in the Pooling and Servicing Agreement as
in  effect  on the  Closing  Date) by  payment  of such  Purchase  Price by wire
transfer  of  immediately  available  funds to the  account  designated  by such
owner(s);  provided, however, that in lieu of effecting any such repurchase, the
Seller will be permitted to deliver a Qualifying Substitute Mortgage Loan and to
pay a cash amount equal to the applicable Substitution Shortfall Amount, subject
to the terms and conditions of the Pooling and Servicing  Agreement as in effect
on the Closing Date.

     If the Seller is notified of a Defect in any Mortgage File that corresponds
to  information  set forth in the  Mortgage  Loan  Schedule,  the  Seller  shall
promptly correct such Defect and provide a new, corrected Mortgage Loan Schedule
to the Purchaser or any successor or assign thereof,  which  corrected  Mortgage
Loan  Schedule  shall be deemed to amend and replace the existing  Mortgage Loan
Schedule for all purposes.

     (b)  Notwithstanding  Section  4(a),  within  60  days  of the  earlier  of
discovery or receipt of notice by the Seller,  from either the  Purchaser or any
successor  or assign  thereof,  that any  Mortgage  Loan does not  constitute  a
"qualified  mortgage" within the meaning of Section  860G(a)(3) of the Code, the
Seller shall repurchase such Mortgage Loan from the then owner(s) thereof at the
applicable  Purchase Price by payment of such Purchase Price by wire transfer of
immediately available funds to the account designated by such owner(s).

     In addition,  if, as of the Closing Date, any Mortgage Loan is secured by a
Mortgage that does not constitute a valid first lien upon the related  Mortgaged
Property,  including all  buildings  located  thereon and all fixtures  attached
thereto,  or if a Mortgage  is subject to  something  other than (A) the lien of
current  real  property  taxes  and  assessments  not yet due and  payable,  (B)
covenants,  conditions  and  restrictions,  rights of way,  easements  and other
matters of public record, (C) exceptions and exclusions specifically referred to
in the lender's title insurance  policy issued or, as evidenced by a "marked-up"
commitment,  to be  issued  in  respect  of such  Mortgage  Loan  and (D)  those
exceptions  set forth on Schedule  B-1 to Exhibit B hereto (the  exceptions  set
forth in the foregoing  clauses (A), (B), (C) and (D)  collectively,  "Permitted
Encumbrances"),  or if the insurer that issued the Title  Policy  referred to in
clause  (vi) of  Exhibit  B  hereto  in  respect  of any  Mortgage  Loan was not
qualified to do business in the state in which the related Mortgaged Property is
located,  and in either case such failure  materially and adversely  affects the
interests  of holder of  Certificates,  (any such failure  that  materially  and
adversely affects


                                       6
<PAGE>


the interests of holders of Certificates,  also a "Breach"), the Seller shall be
required, at its option, to either (i) cure such Breach in all material respects
or (ii)  repurchase  the  affected  Mortgage  Loan,  in each  case,  within  the
applicable  Permitted Cure Period.  If any such Breach is not corrected or cured
in all material respects within the applicable Permitted Cure Period, the Seller
shall, not later than the last day of such Permitted Cure Period, (i) repurchase
the affected  Mortgage Loan from the Purchaser or its assignee at the applicable
Purchase  Price or (ii) if  within  the  three-month  period  commencing  on the
closing date (or within the two-year  period  commencing  on the Closing Date if
the related  Mortgage  Loan is a  "defective  obligation"  within the meaning of
Section   860(a)(4)(B)(ii)   of  the  Code  and  Treasury   Regulation   Section
1.860G-2(f)),  at its  option,  replace  such  Mortgage  Loan with a  Qualifying
Substitute  Mortgage  Loan  and pay  any  corresponding  Substitution  Shortfall
Amount.  The Seller  agrees that any such  repurchase or  substitution  shall be
completed  in  accordance  with and subject to the terms and  conditions  of the
Pooling and Servicing Agreement.

     For purposes of the preceding  paragraph  only, the "Permitted Cure Period"
applicable  to any Defect or Breach in respect of any Mortgage Loan shall be the
90-day period  immediately  following the earlier of the discovery by the Seller
or receipt by the Seller of notice of such Defect or Breach, as the case may be;
provided that if such Defect or Breach,  as the case may be, cannot be corrected
or cured in all material  respects within such 90-day period,  but is reasonably
likely that such Defect or Breach,  as the case may be,  could be  corrected  or
cured  within 180 days of the earlier of  discovery by the Seller and receipt by
the  Seller of notice of such  Defect  or  Breach,  as the case may be,  and the
Seller is  diligently  attempting to effect such  correction  or cure,  then the
applicable Permitted Cure Period shall, with the consent of the Purchaser or its
assignee (which consent shall not be unreasonably  withheld), be extended for an
additional 90 days.

     (c) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan  contemplated by this Section 4, the then owner(s)  thereof shall tender or
cause to be tendered promptly to the Seller, upon delivery of a receipt executed
by the Seller,  the related  Mortgage File and Servicing File, and each document
that  constitutes  a part of the Mortgage  File that was endorsed or assigned to
the Purchaser or the Trustee shall be endorsed or assigned,  as the case may be,
to the Seller or its designee in the same manner.  The form and  sufficiency  of
all such instruments and certificates shall be the responsibility of the Seller.

     (d) This Section 4 provides the sole remedies  available to the  Purchaser,
and its successors and assigns (including,  without  limitation,  the Depositor,
the  Trustee  and the holders of the  Certificates)  respecting  any Defect in a
Mortgage File or any breach of any  representation  or warranty made pursuant to
Section 2(a) and set forth in Exhibit B, or in connection with the circumstances
described  in  Section  4(b).  If the  Seller  defaults  on its  obligations  to
repurchase any Mortgage Loan in accordance with Section 4(a) or 4(b) or disputes
its  obligation to repurchase  any Mortgage Loan in accordance  with either such
subsection,  the Purchaser or its successors and assigns may take such action as
is  appropriate  to enforce  such  payment or  performance,  including,  without
limitation,  the  institution and  prosecution of appropriate  proceedings.  The
Seller shall reimburse the Purchaser for all necessary and reasonable  costs and
expenses incurred in connection with such enforcement.  The remedies provided in
this Section 4


                                       7
<PAGE>


shall replace and amend and restate in their  entirety the provisions of Section
4.3 of the GACC Purchase Agreement with respect to the Mortgage Loans.

SECTION 5. Conveyance of Mortgage Files.

     (a) In connection with the Purchaser's  assignment of the Mortgage Loans to
the Depositor  pursuant to the Mortgage Loan Purchase  Agreement,  the Purchaser
hereby  covenants  with the Seller that,  at least five (5) Business Days before
the Closing Date, it shall have delivered to and deposited with the Trustee, the
Mortgage  File  (as  described  on  Exhibit  B to  the  Mortgage  Loan  Purchase
Agreement)  for each  Mortgage Loan so assigned to the extent that such Mortgage
File was delivered to the Purchaser.  In the event Purchaser fails to so deliver
each such  Mortgage  File to the  Trustee,  the  Seller and its  successors  and
assigns  shall be  entitled  to pursue any rights or remedies in respect of such
failure as may be available under applicable law.

     (b) For the benefit of the Purchaser and its  successors  and assigns,  the
Seller  acknowledges and agrees that the Depositor  intends to cause the Trustee
to perform a limited review of the Mortgage Files relating to the Mortgage Loans
to enable the Trustee to confirm to the  Depositor on or before the Closing Date
that the  Mortgage  Note  referred to in clause (i) of Exhibit B of the Mortgage
Loan Purchase  Agreement has been  delivered to the Trustee with respect to each
such Mortgage File. If the Seller cannot deliver, or cause to be delivered as to
any Mortgage Loan,  the original  Mortgage Note, the Seller shall deliver a copy
or  duplicate  original  of such  Mortgage  Note,  together  with  an  affidavit
certifying that the original  thereof has been lost or destroyed.  If the Seller
cannot deliver, or cause to be delivered,  as to any Mortgage Loan, the original
or a copy of any of the  documents  and/or  instruments  referred  to in clauses
(ii), (iv), (viii), (xi)(A) and (xii) of Exhibit B of the Mortgage Loan Purchase
Agreement,  with evidence of recording thereon, solely because of a delay caused
by the public  recording or filing office where such document or instrument  has
been  delivered for  recordation  or filing,  or because such original  recorded
document  has been lost or  returned  from the  recording  or filing  office and
subsequently lost, as the case may be, the delivery requirements of this Section
5 shall be deemed to have  been  satisfied  as to such  missing  item,  and such
missing item shall be deemed to have been included in the related Mortgage File,
provided  that a copy  of such  document  or  instrument  (without  evidence  of
recording or filing  thereon,  but certified  (which  certificate  may relate to
multiple  documents and/or  instruments) by the Seller to be a true and complete
copy of the original thereof  submitted for recording or filing, as the case may
be) has been  delivered to the Trustee,  and either the original of such missing
document or instrument, or a copy thereof, with evidence of recording or filing,
as the  case  may  be,  thereon,  is  delivered  to or at the  direction  of the
Depositor or Trustee  within 180 days of the Closing Date (or within such longer
period  after the Closing  Date as the Trustee  (or such  subsequent  owner) may
consent to,  which  consent  shall not be  unreasonably  withheld so long as the
Seller has provided the Depositor or Trustee with evidence of such  recording or
filing,  as the case may be, or has  certified to the Depositor or Trustee as to
the  occurrence  of such  recording  or  filing,  as the case may be, and is, as
certified to the Trustee no less often than quarterly,  in good faith attempting
to obtain from the appropriate  county recorder's or filing office such original
or copy).

     (c) If the  Seller  cannot  deliver,  or cause to be  delivered,  as to any
Mortgage  Loan, the original or a copy of the related  lender's title  insurance
policy  referred to in clause (ix) of Exhibit B of the  Mortgage  Loan  Purchase
Agreement solely because such policy has not yet been issued,


                                       8
<PAGE>


the delivery  requirements  of this Section 5 shall be deemed to be satisfied as
to such  missing  item,  and such  missing  item  shall be  deemed  to have been
included in the related Mortgage File, provided that the Seller has delivered to
the Trustee a commitment for title insurance  "marked-up" at the closing of such
Mortgage  Loan,  and the  Seller  shall  deliver to or at the  direction  of the
Depositor  or Trustee,  promptly  following  the receipt  thereof,  the original
related  lender's  title  insurance  policy (or a copy  thereof).  In  addition,
notwithstanding  anything to the contrary contained herein, if there exists with
respect to any group of  related  cross-collateralized  Mortgage  Loans only one
original of any document  referred to in Exhibit B of the Mortgage Loan Purchase
Agreement  covering all the Mortgage Loans in such group,  then the inclusion of
the original of such document in the Mortgage File for any of the Mortgage Loans
in such group shall be deemed an inclusion of such original in the Mortgage File
for each such Mortgage Loan.

     (d) As to each Mortgage Loan, the Seller shall be responsible for all costs
associated  with (i) the  recording  or  filing,  as the  case  may be,  of each
assignment  referred  to in clauses  (iii) and (v) of Exhibit B to the  Mortgage
Loan Agreement and each UCC-2 and UCC-3,  if any,  referred to in clause (xi)(B)
of Exhibit B to the Mortgage Loan Purchase  Agreement and (ii) the delivery of a
copy  of any  such  document  or  instrument  to the  Master  Servicer  promptly
following  its return to the Trustee or its  designee  after such  recording  or
filing; provided that the Seller shall not be responsible for actually recording
or filing any such document or instrument. If any such document or instrument is
lost or returned  unrecorded or unfiled, as the case may be, because of a defect
therein,  the  Seller  shall  promptly  prepare  or cause the  preparation  of a
substitute  therefor or cure or cause the curing of such defect, as the case may
be, and shall thereafter  deliver the substitute or corrected  document to or at
the  direction  of the  Depositor  or the Trustee for  recording  or filing,  as
appropriate, at the Seller's expense.

SECTION 6. Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,

representation,  warranty or covenant of this  Agreement  that is  prohibited or
unenforceable  or  is  held  to be  void  or  unenforceable  in  any  particular

particular  jurisdiction  shall  not  invalidate  or render  unenforceable  such

jurisdiction.  To the extent  permitted by  applicable  law, the parties  hereto
waive any provision of law which prohibits or renders void or unenforceable  any
provision hereof.

                                    EXHIBIT A

                             MORTGAGE LOAN SCHEDULE


<PAGE>


                                    EXHIBIT B

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER
                     REGARDING THE INDIVIDUAL MORTGAGE LOANS


     With  respect to each  Mortgage  Loan,  the Seller  hereby  represents  and
warrants, as of the date hereinbelow specified or, if no such date is specified,
as of the Closing Date, except as set forth on Schedule B-1 hereto, that:

     (i) Ownership of Mortgage Loans.  Immediately prior to the transfer thereof
to the Depositor,  the Purchaser had good and  marketable  title to, and was the
sole owner and  holder of,  such  Mortgage  Loan,  free and clear of any and all
liens,  encumbrances  and other interests on, in or to such Mortgage Loan (other
than,  in certain  cases,  the right of a subservicer  to directly  service such
Mortgage Loan). Such transfer validly assigns ownership of such Mortgage Loan to
the  Depositor  free and clear of any  pledge,  lien,  encumbrance  or  security
interest.

     (ii) Authority to Transfer Mortgage Loans. The Purchaser has full right and
authority to sell,  assign and transfer such Mortgage  Loan. No provision of the
Mortgage  Note,  Mortgage or other loan document  relating to such Mortgage Loan
prohibits or restricts the Purchaser's right to assign or transfer such Mortgage
Loan.

     (iii) Mortgage Loan Schedule.  The information  pertaining to such Mortgage
Loan set forth in the Mortgage  Loan  Schedule  attached as Exhibit A hereto was
true and correct in all material respects as of the Cut-off Date.

     (iv) Payment Record.  Such Mortgage Loan was not as of the Cut-off Date for
such  Mortgage  Loan,  and has not been  during the  twelve-month  period  prior
thereto,  30 days or more  delinquent  in  respect of any debt  service  payment
required thereunder, without giving effect to any applicable grace period.

     (v) Permitted  Encumbrances.  The Permitted Encumbrances (as defined in the
Agreement of which this Exhibit B forms a part) do not materially interfere with
the security intended to be provided by the related Mortgage, the current use or
operation  of the  related  Mortgaged  Property  or the  current  ability of the
Mortgaged  Property to generate net operating  income  sufficient to service the
Mortgage Loan. If the Mortgaged  Property is operated as a nursing  facility,  a
hospitality property or a multifamily property, the Mortgage,  together with any
separate security agreement,  similar agreement and UCC financing statement,  if
any,  establishes  and creates a first  priority,  perfected  security  interest
(subject only to any prior purchase money security interest), to the extent such
security  interest  can be  perfected  by the  recordation  of a Mortgage or the
filing of a UCC  financing  statement,  in all  personal  property  owned by the
Mortgagor that is used in, and is reasonably  necessary to, the operation of the
related Mortgaged Property.

     (vi) Title  Insurance.  The lien of the  related  Mortgage is insured by an
ALTA lender's  title  insurance  policy ("Title  Policy"),  or its equivalent as
adopted in the applicable jurisdiction,  issued by a nationally recognized title
insurance company, insuring the originator of such Mortgage Loan, its successors
and  assigns,  as to the first  priority  lien of the  Mortgage in the


                                       B-1
<PAGE>


original  principal amount of the Mortgage Loan after all advances of principal,
subject only to Permitted  Encumbrances (or, if a title insurance policy has not
yet been issued in respect of the Mortgage  Loan, a policy meeting the foregoing
description is evidenced by a commitment for title insurance  "marked-up" at the
closing of such loan).  Each Title  Policy (or, if it has yet to be issued,  the
coverage to be  provided  thereby)  is in full force and  effect,  all  premiums
thereon have been paid and, to the Seller's  knowledge,  no material claims have
been made thereunder and no claims have been paid thereunder. Neither the Seller
nor the Purchaser has, by act or omission,  done anything that would  materially
impair the coverage under such Title Policy.  Immediately following the transfer
and  assignment of the related  Mortgage Loan to the Trustee,  such Title Policy
(or, if it has yet to be issued, the coverage to be provided thereby) will inure
to the benefit of the Trustee without the consent of or notice to the insurer.

     (vii) No Waivers by Seller of Material Defaults. Neither the Seller nor the
Purchaser  has  waived  any  material  default,  breach,  violation  or event of
acceleration existing under the related Mortgage or Mortgage Note.

     (viii) No Offsets,  Defenses or  Counterclaims.  There is no valid  offset,
defense or counterclaim to such Mortgage Loan.

     (ix)  Condition  of  Property;  Condemnation.  Except  as set  forth in any
engineering  report  prepared in connection with the origination of (or obtained
in  connection  with or otherwise  following the Seller's  acquisition  of) such
Mortgage Loan,  the related  Mortgaged  Property is, to the Seller's  knowledge,
free and clear of any damage  that would  materially  and  adversely  affect its
value as security for such Mortgage Loan. The Seller has no actual notice of the
commencement of a proceeding for the condemnation of all or any material portion
of the related Mortgaged Property.

     (x)  Compliance  with Usury Laws.  Such  Mortgage  Loan  complied  with all
applicable usury laws in effect at its date of origination.

     (xi) Full  Disbursement  of Mortgage  Loan  Proceeds.  The proceeds of such
Mortgage Loan have been fully  disbursed and there is no requirement  for future
advances thereunder.

     (xii) Enforceability.  The related Mortgage Note and Mortgage and all other
documents  and  instruments  evidencing,  guaranteeing,  insuring  or  otherwise
securing such Mortgage Loan have been duly and properly  executed by the parties
thereto,  and each is the  legal,  valid  and  binding  obligation  of the maker
thereof  (subject  to  any  non-recourse  provisions  contained  in  any  of the
foregoing  agreements and any  applicable  state  anti-deficiency  legislation),
enforceable  in accordance  with its terms,  except as such  enforcement  may be
limited by bankruptcy, insolvency,  reorganization,  receivership, moratorium or
other laws  relating to or affecting  the rights of creditors  generally  and by
general  principles  of  equity  (regardless  of  whether  such  enforcement  is
considered in a proceeding in equity or at law).

     (xiii) Insurance.  All improvements upon the related Mortgaged Property are
insured against loss by hazards of extended  coverage in an amount (subject to a
customary  deductible) at least equal to the lesser of the outstanding principal
balance  of such  Mortgage  Loan and 100% of the  full  replacement  cost of the
improvements located on such Mortgaged Property and the


                                      B-2
<PAGE>


related hazard insurance policy contains  appropriate  endorsements to avoid the
application  of  co-insurance  provisions  and  does  not  permit  reduction  in
insurance  proceeds for  depreciation.  If any portion of the related  Mortgaged
Property was, at the time of the  origination  of such Mortgage Loan, in an area
identified in the Federal Register by the Federal Emergency Management Agency as
having  special  flood  hazards,  and flood  insurance  was  available,  a flood
insurance policy meeting any requirements of the then current  guidelines of the
Federal  Insurance  Administration  is in  effect  with a  generally  acceptable
insurance carrier, in an amount representing coverage not less than the least of
(1) the  outstanding  principal  balance  of such  Mortgage  Loan,  (2) the full
insurable value of such Mortgaged Property,  (3) the maximum amount of insurance
available  under the National Flood  Insurance Act of 1968, as amended,  and (4)
100% of the  replacement  cost of the  improvements  located  on such  Mortgaged
Property.  In  addition,  the  Mortgage  requires  the  Mortgagor to maintain in
respect of the Mortgaged Property  comprehensive  general liability insurance in
amounts  generally  required  by the Seller,  and at least six months  rental or
business interruption insurance, and all such insurance required by the Mortgage
to be  maintained  is in full  force  and  effect.  Each such  insurance  policy
requires  prior  notice  to  the  holder  of  the  Mortgage  of  termination  or
cancellation,  and no such  notice has been  received,  including  any notice of
nonpayment of premiums, that has not been cured.

     (xiv) Environmental  Condition.  The related Mortgaged Property was subject
to one or more  environmental  site  assessments  (or an update of a  previously
conducted assessment), which was (were) performed on behalf of the Seller, or as
to which the related  report was delivered to the Seller in connection  with its
origination or acquisition of such Mortgage Loan; and the Seller, having made no
independent   inquiry  other  than  reviewing  the  resulting  report(s)  and/or
employing an environmental  consultant to perform the  assessment(s)  referenced
herein, has no knowledge of any material and adverse environmental conditions or
circumstance  affecting  such  Mortgaged  Property that was not disclosed in the
related  report(s).  The Seller has not taken any  action  with  respect to such
Mortgage  Loan  or  the  related  Mortgaged  Property  that  could  subject  the
Purchaser, or its successors and assigns in respect of the Mortgage Loan, to any
liability  under the  Comprehensive  Environmental  Response,  Compensation  and
Liability Act of 1980, as amended  ("CERCLA") or any other  applicable  federal,
state or local  environmental  law,  and the Seller has not  received any actual
notice of a material  violation of CERCLA or any  applicable  federal,  state or
local  environmental law with respect to the related Mortgaged Property that was
not disclosed in the related report.  The related  Mortgage or loan documents in
the related  Mortgage File requires the Mortgagor to comply with all  applicable
federal, state and local environmental laws and regulations.

     (xv) No  Cross-Collateralization  with Other Mortgage Loans.  Such Mortgage
Loan is not  cross-collateralized  with  any  mortgage  loan  that  will  not be
included in the Trust Fund.

     (xvi) Waivers and Modifications.  The terms of the related Mortgage and the
Mortgage  Note  have not been  impaired,  waived,  altered  or  modified  in any
material respect, except as specifically set forth in the related Mortgage File.

     (xvii) Taxes and Assessments.  There are no delinquent taxes, ground rents,
assessments for improvements or other similar  outstanding charges affecting the
related  Mortgaged  Property which are or may become a lien of priority equal to
or  higher  than  the  lien  of the  related  Mortgage.  For  purposes  of  this
representation and warranty, real property taxes and assessments


                                      B-3
<PAGE>


shall not be considered unpaid until the date on which interest and/or penalties
would be payable thereon.

     (xviii)  Mortgagor's  Interest in Mortgaged  Property.  The interest of the
related  Mortgagor in the related  Mortgaged  Property  consists of a fee simple
estate in real property.

     (xix)  Whole  Loan.   Each  Mortgage  Loan  is  a  whole  loan  and  not  a
participation interest.

     (xx)  Valid  Assignment.  The  original  assignment  of  the  Mortgage,  in
recordable form, executed by the most recent assignee of record thereof prior to
the Trustee or, if none, by the  originator,  either in blank or in favor of the
Trustee (in such capacity)  included in the Mortgage File constitutes the legal,
valid and binding  assignment of such Mortgage from the relevant assignor to the
Trustee. The Assignment of Leases set forth in the Mortgage or separate from the
related  Mortgage and related to and delivered in connection  with each Mortgage
Loan establishes and creates a valid,  subsisting and, subject only to Permitted
Encumbrances,  enforceable  first  priority  lien and  first  priority  security
interest in the related Mortgagor's interest in all leases, subleases,  licenses
or other agreements  pursuant to which any person is entitled to occupy,  use or
possess all or any portion of the real property subject to the related Mortgage,
and each assignor  thereunder has the full right to assign the same. The related
assignment of any Assignment of Leases, not included in a Mortgage, executed and
delivered in favor of the Trustee is in recordable form and constitutes a legal,
valid and binding assignment, sufficient to convey to the assignee named therein
all of the assignor's right, title and interest in, to and under such Assignment
of Leases.

     (xxi) Escrows. All escrow deposits relating to such Mortgage Loan that are,
as of the Closing Date, required to be deposited with the mortgagee or its agent
have been so deposited.

     (xxii) No Mechanics' or Materialmen's  Liens. As of the date of origination
of such  Mortgage  Loan and, to the actual  knowledge  of the Seller,  as of the
Closing Date,  the related  Mortgaged  Property was and is free and clear of any
mechanics' and materialmen's liens or liens in the nature thereof which create a
lien prior to that  created by the  related  Mortgage,  except  those  which are
insured against by the Title Policy referred to in (vi) above.

     (xxiii) No Material  Encroachments.  To the  Seller's  knowledge  (based on
surveys and/or title  insurance  obtained in connection  with the origination of
such Mortgage Loan), as of the date of such origination, no improvement that was
included  for the  purpose of  determining  the  appraised  value of the related
Mortgaged  Property at the time of origination of such Mortgage Loan lay outside
the boundaries and building  restriction  lines of such property to any material
extent  (unless  affirmatively  covered by the title  insurance  referred  to in
paragraph (vi) above),  and no improvements on adjoining  properties  encroached
upon such Mortgaged Property to any material extent. To the Seller's  knowledge,
based upon opinions of counsel and/or other due diligence  customarily performed
by the Seller,  the  improvements  located on or forming part of such  Mortgaged
Property  comply  in all  material  respects  with  applicable  zoning  laws and
ordinances  (except to the extent that they may constitute legal  non-conforming
uses).

     (xxiv) Originator  Authorized.  To the extent required under applicable law
as of the Closing Date,  the  originator of such Mortgage Loan was authorized to
do business in the


                                      B-4
<PAGE>


jurisdiction  in which the  related  Mortgaged  Property is located at all times
when  it  held  the  Mortgage  Loan  to  the  extent  necessary  to  ensure  the
enforceability of such Mortgage Loan.

     (xxv) No Material Default.  (A) To the Seller's knowledge,  there exists no
material default,  breach or event of acceleration under the related Mortgage or
Mortgage  Note,  and (B) the Seller has not received  actual notice of any event
(other than payments due but not yet delinquent)  that, with the passage of time
or with notice and the expiration of any grace or cure period,  would constitute
such a material  default,  breach or event of acceleration;  provided,  however,
that this  representation  and warranty  does not cover any  default,  breach or
event of acceleration that specifically pertains to any matter otherwise covered
or addressed by any other representation and warranty made by the Seller herein.

     (xxvi)  Inspection.  In connection  with the  origination or acquisition of
each Mortgage Loan, the Seller inspected or caused to be inspected the Mortgaged
Property.

     (xxvii) No Equity Participation or Contingent  Interest.  The Mortgage Loan
contains no equity  participation  by the  lender,  and does not provide for any
contingent or additional  interest in the form of participation in the cash flow
of the related Mortgaged Property, or for negative amortization.

     (xxviii) No Advances of Funds.  No holder of the Mortgage  Loan has, to the
Seller's knowledge,  advanced funds or induced,  solicited or knowingly received
any advance of funds from a party other than the owner of the related  Mortgaged
Property,  directly or indirectly, for the payment of any amount required by the
Mortgage Loan.

     (xxix)  Licenses,  Permits,  Etc. To the Seller's  knowledge,  based on due
diligence  customarily performed in the origination of comparable mortgage loans
by the Seller,  as of the date of  origination of the Mortgage Loan, the related
Mortgagor or operator of the related Mortgaged Property was in possession of all
material licenses,  permits and  authorizations  required by applicable laws for
the  ownership and  operation of the related  Mortgaged  Property as it was then
operated and if a related  Mortgaged  Property is improved by a skilled nursing,
congregate  care or assisted  living  facility,  the most recent  inspection  or
survey by governmental  authorities having  jurisdiction in connection with such
licenses,  permits and  authorizations  did not cite such Mortgaged Property for
material  violations  (which  shall  include  only  "Level  A"  (or  equivalent)
violations in the case of skilled nursing facilities) that had not been cured or
as to which a plan of correction  had not been submitted to and accepted by such
governmental  authorities.  To the extent such facility participates in Medicaid
or Medicare,  such facility is in  compliance in all material  respects with the
requirements of such program.

     (xxx) Servicing.  The servicing and collection  practices used with respect
to the Mortgage Loan have complied with applicable law in all material  respects
and are consistent  with the servicing  standard set forth in Section 3.01(a) of
the Pooling and Servicing Agreement.

     (xxxi) Customary Remedies.  The related Mortgage or Mortgage Note, together
with  applicable  state  law,  contains  customary  and  enforceable  provisions
(subject to the exceptions  set forth in paragraph  (xii)) such as to render the
rights and remedies of the holders thereof adequate


                                      B-5
<PAGE>


for the  practical  realization  against the related  Mortgaged  Property of the
principal benefits of the security intended to be provided thereby.

     (xxxii) Insurance and Condemnation  Proceeds. The related Mortgage provides
that insurance proceeds and condemnation proceeds will be applied for one of the
following purposes:  either to restore or repair the Mortgaged  Property,  or to
repay the  principal  of the  Mortgage  Loan,  or otherwise at the option of the
holder of the Mortgage.

     (xxxiii)  LTV.  The gross  proceeds  of such  Mortgage  Loan to the related
Mortgagor at origination did not exceed the  non-contingent  principal amount of
the Mortgage  Loan and either:  (A) such Mortgage Loan is secured by an interest
in real  property  having a fair market value (1) at the date the Mortgage  Loan
was originated at least equal to 80 percent of the original principal balance of
the Mortgage Loan or (2) at the Closing Date at least equal to 80 percent of the
principal balance of the Mortgage Loan on such date;  provided that for purposes
hereof,  the fair  market  value of the real  property  interest  must  first be
reduced  by (X) the  amount of any lien on the real  property  interest  that is
senior to the Mortgage Loan and (Y) 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 clauses (1) and (2) of this paragraph (xxxiii) shall be
made on a pro rata  basis in  accordance  with the  fair  market  values  of the
Mortgaged Properties securing such  cross-collateralized  Mortgage Loans; or (B)
substantially  all the  proceeds  of such  Mortgage  Loan were used to  acquire,
improve or protect the real property  which served as the only security for such
Mortgage  Loan  (other  than a recourse  feature  or other  third  party  credit
enhancement    within   the    meaning   of   Treasury    Regulations    Section
1.860G-2(a)(1)(ii)).

     (xxxiv)  LTV  and  Significant  Modifications.  If the  Mortgage  Loan  was
"significantly  modified" prior to the Closing Date so as to result in a taxable
exchange  under Section 1001 of the Code, it either (A) was modified as a result
of the default or  reasonably  foreseeable  default of such Mortgage Loan or (B)
satisfies  the  provisions  of  either  clause  (A)(1)  of  paragraph   (xxxiii)
(substituting  the date of the last such  modification for the date the Mortgage
Loan was  originated)  or clause  (A)(2) of paragraph  (xxxiii),  including  the
proviso thereto.

     (xxxv) [Reserved]

     (xxxvi) Litigation. To the Seller's actual knowledge,  there are no pending
actions,  suits or proceedings by or before any court or governmental  authority
against or affecting  the related  Mortgagor or the related  Mortgaged  Property
that, if determined  adversely to such  Mortgagor or Mortgaged  Property,  would
materially  and  adversely  affect the value of the  Mortgaged  Property  or the
ability of the  Mortgagor to pay  principal,  interest or any other  amounts due
under such Mortgage Loan.

     (xxxvii) Leasehold Estate.  Each Mortgaged Property consists of the related
Mortgagor's fee simple  interest in real estate or the related  Mortgage Loan is
secured in whole or in part by the interest of the Mortgagor as a lessee under a
ground lease of the  Mortgaged  Property (a "Ground  Lease").  Any Mortgage Loan
that is secured by the interest of the Mortgagor under a Ground Lease may or may
not be secured by the related fee interest in such Mortgaged  Property (the "Fee
Interest"). If a Mortgage Loan is secured in whole or in part by a Ground Lease,
either


                                      B-6
<PAGE>


(1) the ground  lessor's Fee Interest is  subordinated to the lien of the
Mortgage or (2) the following apply to such Ground Lease:

(A)  To the actual knowledge of the Seller,  based on due diligence  customarily
     performed in the  origination  of comparable  mortgage loans by the Seller,
     such  Ground  Lease  or a  memorandum  thereof  has  been  or  will be duly
     recorded;  such  Ground  Lease (or the  related  estoppel  letter or lender
     protection  agreement  between the Seller and related  lessor)  permits the
     interest of the lessee thereunder to be encumbered by the related Mortgage;
     and there has been no material  change in the payment  terms of such Ground
     Lease  since  the  origination  of the  related  Mortgage  Loan,  with  the
     exception of material changes  reflected in written  instruments that are a
     part of the related Mortgage File;

(B)  The  lessee's  interest in such Ground Lease is not subject to any liens or
     encumbrances  superior to, or of equal priority with, the related Mortgage,
     other  than  the  ground  lessor's   related  fee  interest  and  Permitted
     Encumbrances;

(C)  The  Mortgagor's  interest  in  such  Ground  Lease  is  assignable  to the
     Purchaser  and its  successors  and assigns upon notice to, but without the
     consent of, the lessor thereunder (or, if such consent is required,  it has
     been  obtained  prior to the Closing  Date) and, in the event that it is so
     assigned,  is further  assignable by the Purchaser and its  successors  and
     assigns upon notice to, but without the need to obtain the consent of, such
     lessor;

(D)  Such Ground Lease is in full force and effect,  and the Seller has received
     no notice that an event of default  has  occurred  thereunder,  and, to the
     Seller's  actual  knowledge,  there exists no condition  that,  but for the
     passage of time or the giving of notice,  or both, would result in an event
     of default under the terms of such Ground Lease;

(E)  Such Ground Lease, or an estoppel letter or other  agreement,  requires the
     lessor  under such Ground Lease to give notice of any default by the lessee
     to the mortgagee,  provided that the mortgagee under such Mortgage Loan has
     provided  the  lessor  with  notice  of its  lien in  accordance  with  the
     provisions  of such Ground  Lease,  and such Ground  Lease,  or an estoppel
     letter or other  agreement,  further provides that no notice of termination
     given under such Ground Lease is effective  against the mortgagee  unless a
     copy has been delivered to the mortgagee;

(F)  The   mortgagee   under  such  Mortgage  Loan  is  permitted  a  reasonable
     opportunity (including, where necessary, sufficient time to gain possession
     of the interest of the lessee under such Ground  Lease) to cure any default
     under such Ground  Lease,  which is curable  after the receipt of notice of
     any such default,  before the lessor  thereunder  may terminate such Ground
     Lease;

(G)  Such Ground Lease has an original term (including any extension options set
     forth  therein)  which  extends  not less than ten years  beyond the Stated
     Maturity Date of the related Mortgage Loan;


                                      B-7
<PAGE>


(H)  Under  the  terms of such  Ground  Lease and the  related  Mortgage,  taken
     together,  any related insurance  proceeds other than in respect of a total
     or substantially total loss or taking, will be applied either to the repair
     or restoration of all or part of the related Mortgaged  Property,  with the
     mortgagee under such Mortgage Loan or a trustee  appointed by it having the
     right to hold and  disburse  such  proceeds  as the  repair or  restoration
     progresses (except in such cases where a provision  entitling another party
     to hold and  disburse  such  proceeds  would not be viewed as  commercially
     unreasonable by a prudent commercial mortgage lender), or to the payment of
     the  outstanding  principal  balance of the Mortgage Loan together with any
     accrued interest thereon;

(I)  Such Ground  Lease does not impose any  restrictions  on  subletting  which
     would be viewed,  as of the date of  origination  of the  related  Mortgage
     Loan, as  commercially  unreasonable  by the Seller;  and such Ground Lease
     contains a covenant  that the lessor  thereunder is not  permitted,  in the
     absence of an uncured default, to disturb the possession, interest or quiet
     enjoyment  of any  subtenant of the lessee,  or in any manner,  which would
     materially  adversely affect the security provided by the related Mortgage;
     and

(J)  Such Ground Lease, or an estoppel letter or other  agreement,  requires the
     lessor  to enter  into a new  lease in the  event of a  termination  of the
     Ground  Lease by reason  of a default  by the  Mortgagor  under the  Ground
     Lease, including, rejection of the ground lease in a bankruptcy proceeding.

     (xxxviii)  Deed of Trust.  If the related  Mortgage  is a deed of trust,  a
trustee,  duly  qualified  under  applicable  law to serve as such,  is properly
designated and serving under such Mortgage.

     (xxxix)  Lien  Releases.  Except in cases  where  either (a) a release of a
portion  of the  Mortgaged  Property  was  contemplated  at  origination  of the
Mortgage  Loan and such  portion was not  considered  material  for  purposes of
underwriting   the  Mortgage  Loan  or  (b)  release  is  conditioned  upon  the
satisfaction of certain underwriting and legal requirements and the payment of a
release price, the related Mortgage Note or Mortgage does not require the holder
thereof to release all or any portion of the Mortgaged Property from the lien of
the related  Mortgage  except upon payment in full of all amounts due under such
Mortgage Loan.

     (xl) Junior Liens. The Mortgage Loan does not permit the related  Mortgaged
Property to be  encumbered  by any lien junior to or of equal  priority with the
lien of the related  Mortgage  (excluding any lien relating to another  Mortgage
Loan that is  cross-collateralized  with such  Mortgage  Loan) without the prior
written  consent  of the  holder  thereof or the  satisfaction  of debt  service
coverage or similar conditions specified therein.

     (xli) Mortgagor Bankruptcy. To the Seller's knowledge, the Mortgagor is not
a debtor in any state or federal bankruptcy or insolvency proceeding.


                                      B-8
<PAGE>


     (xlii) Due  Organization  of  Mortgagors.  As of the date of origination of
each  Mortgage,  each related  Mortgagor  which is not a natural person was duly
organized and validly existing under the laws of the state of its jurisdiction.

     (xliii)  Due-On-Sale.   The  Mortgage  Loan  contains  provisions  for  the
acceleration  of the payment of the unpaid  principal  balance of such  Mortgage
Loan if,  without  complying  with the  requirements  of such Mortgage Loan, the
related Mortgaged Property,  or any controlling interest therein, is directly or
indirectly transferred or sold.

     (xliv) Single Purpose  Entity.  The related  Mortgagor is an entity,  other
than an individual,  whose organizational documents or the related Mortgage Loan
Documents provide substantially to the effect that the Mortgagor:  (A) is formed
or organized  solely for the purpose of owning and  operating one or more of the
Mortgaged  Properties  securing  the Mortgage  Loans,  (B) may not engage in any
business unrelated to such Mortgaged Property or Mortgaged Properties,  (C) does
not have any  material  assets  other than those  related to its interest in and
operation of such Mortgage Property or Mortgaged  Properties,  (D) may not incur
indebtedness  other than as permitted by the related  Mortgage or other Mortgage
Loan  Documents,  (E) has its own books and records  separate and apart from any
other  person,  and (F) holds itself out as a legal  entity,  separate and apart
from any other person.

     (xlv) Defeasance  Provisions.  Any Mortgage Loan which contains a provision
for any defeasance of mortgage collateral either (A) requires the consent of the
holder of the Mortgage Loan to any defeasance,  or (B) permits defeasance (i) no
earlier  than two years  after the  Closing  Date (as defined in the Pooling and
Servicing  Agreement,  dated as of August 1,  1998),  (ii) only with  substitute
collateral  constituting  "government  securities"  within the meaning of Treas.
Reg. ss.  1.860G-2(a)(8)(i),  and (iii) only to facilitate  the  disposition  of
mortgage real property and not as a part of an  arrangement to  collateralize  a
REMIC offering with obligations that are not real estate mortgages.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Exhibit B shall survive delivery of the respective  Mortgage Files
to the  Purchaser,  the  Depositor  and/or the  Trustee  and shall  inure to the
benefit of the  Purchaser,  and its successors  and assigns  (including  without
limitation  the  Depositor,  the Trustee  and the holders of the  Certificates),
notwithstanding any restrictive or qualified endorsement or assignment.

                                                                  EXECUTION COPY


                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of February 2, 1999,  between  Restructured Asset Certificates With
Enhanced  Returns,  Series  1998-ML  Trust as seller  (the  "Seller"),  of which
LaSalle  National Bank is the trustee (in such capacity,  the "Seller  Trustee")
and GMAC Commercial Mortgage Securities, Inc. as purchaser (the "Purchaser").

     The Seller desires to sell,  assign,  transfer and otherwise  convey to the
Purchaser,  and the  Purchaser  desires  to  purchase,  subject to the terms and
conditions set forth below,  the multifamily and commercial  mortgage loans (the
"Mortgage  Loans")  identified on the schedule  annexed hereto as Exhibit A (the
"Mortgage Loan Schedule").

     It is expected that the Mortgage Loans will be  transferred,  together with
other  multifamily  and  commercial  mortgage  loans to a trust fund (the "Trust
Fund") to be formed by the  Purchaser,  beneficial  ownership  of which  will be
evidenced   by   a   series   of   mortgage   pass-through   certificates   (the
"Certificates"). Certain classes of the Certificates will be rated by Standard &
Poor's Ratings Services and Fitch IBCA Inc.  (together,  the "Rating Agencies").
Certain classes of the  Certificates  (the  "Registered  Certificates")  will be
registered under the Securities Act of 1933, as amended (the "Securities  Act").
The Trust Fund will be created and the Certificates will be issued pursuant to a
pooling and servicing agreement to be dated as of February 1, 1999 (the "Pooling
and Servicing  Agreement"),  among the Purchaser as depositor,  GMAC  Commercial
Mortgage  Corporation  as  master  servicer  (in  such  capacity,   the  "Master
Servicer") and special servicer (in such capacity,  the "Special  Servicer") and
Norwest Bank Minnesota,  National Association, as trustee (in such capacity, the
"Trustee").  Capitalized  terms not otherwise  defined  herein have the meanings
assigned  to them in the  Pooling and  Servicing  Agreement  as in effect on the
Closing Date (as defined below).

     The Purchaser  intends to sell the Class A-1,  Class A-2, Class B, Class C,
Class D, Class E and a portion of the Class X Certificates  to Goldman,  Sachs &
Co., Deutsche Bank Securities Inc. and Donaldson,  Lufkin & Jenrette  Securities
Corporation (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  The Purchaser intends to
sell a portion of the Class X Certificates to GMACCM (in such capacity, a "Class
X Certificate  Purchaser")  pursuant to a Class X Certificate Purchase Agreement
dated the date  hereof  (the  "Class X  Certificate  Purchase  Agreement").  The
Purchaser  intends  to sell the Class F,  Class G,  Class H, Class J and Class K
Certificates to GMACCM (in such capacity,  an "Initial Purchaser") pursuant to a
Certificate Purchase Agreement dated the date hereof (the "Certificate  Purchase
Agreement").  The  Purchaser  intends to sell the Class R-I,  Class R-II and the
Class R-III Certificates to Goldman,  Sachs & Co. (in such capacity, an "Initial
Purchaser").  The Class F, Class G, Class H, Class J, Class K, Class R-I,  Class
R-II  and  Class  R-III  Certificates  are  collectively   referred  to  as  the
"Non-Registered Certificates."

     Now, therefore,  in consideration of the premises and the mutual agreements
set forth herein, the parties agree as follows:


<PAGE>


     SECTION 1. Agreement to Purchase.

     The Seller agrees to sell,  assign,  transfer and  otherwise  convey to the
Purchaser,  and the  Purchaser  agrees to  purchase,  the  Mortgage  Loans.  The
purchase and sale of the Mortgage  Loans shall take place on February 9, 1999 or
such other date as shall be  mutually  acceptable  to the  parties  hereto  (the
"Closing Date"). The "Cut-off Date" with respect to any Mortgage Loan is the Due
Date for such  Mortgage  Loan in February  1999.  As of the close of business on
their respective  Cut-off Dates (which Cut-off Dates may occur after the Closing
Date),  the  Mortgage  Loans  will  have an  aggregate  principal  balance  (the
"Aggregate  Cut-off  Date  Balance"),  after  application  of  all  payments  of
principal  due  thereon on or before  such date,  whether  or not  received,  of
$15,278,290,  subject to a variance of plus or minus 5%. The purchase  price for
the  Mortgage  Loans shall be  determined  pursuant to a certain  Mortgage  Loan
Purchase Agreement, dated as of June 30, 1998.

     SECTION 2. Conveyance of Mortgage Loans.

     (a) Effective as of the Closing Date, subject only to receipt by the Seller
of the  purchase  price  referred  to in  Section  1  hereof  (exclusive  of any
applicable  holdback  for  transaction  expenses),  the Seller does hereby sell,
transfer,  assign,  set over and  otherwise  convey  to the  Purchaser,  without
recourse, all the right, title and interest of the Seller in and to the Mortgage
Loans  identified on the Mortgage  Loan Schedule as of such date,  including all
interest and  principal  received or receivable by the Seller on or with respect
to the Mortgage  Loans after the Cut-off Date for each Mortgage  Loan,  together
with all of the Seller's right, title and interest in and to the proceeds of any
related title,  hazard, or other insurance  policies and any escrow,  reserve or
other comparable  accounts related to the Mortgage Loans. The Purchaser shall be
entitled to (and,  to the extent  received  by or on behalf of the  Seller,  the
Seller  shall  deliver or cause to be  delivered  to or at the  direction of the
Purchaser) all scheduled  payments of principal and interest due on the Mortgage
Loans after the Cut-off Date for such Mortgage Loan, and all other recoveries of
principal and interest  collected thereon after such Cut-off Date. All scheduled
payments of principal and interest due thereon on or before the Cut-off Date for
each  Mortgage  Loan and  collected  after such Cut-off Date shall belong to the
Seller.

     (b) In connection with the Seller's  assignment  pursuant to subsection (a)
above, the Seller hereby agrees that, at least five (5) Business Days before the
Closing Date, it shall have  delivered to and  deposited  with the Trustee,  the
Mortgage  File (as  described  on Exhibit B hereto)  for each  Mortgage  Loan so
assigned to the extent that such Mortgage File was delivered to the Seller.

     (c) All  documents  and records in the  Seller's  possession  (or under its
control)  relating to the Mortgage Loans that are not required to be a part of a
Mortgage  File in  accordance  with  Exhibit B (all  such  other  documents  and
records,  as to any Mortgage  Loan,  the  "Servicing  File"),  together with all
escrow  payments,  reserve funds and other comparable funds in the possession of
the Seller (or under its  control)  with respect to the  Mortgage  Loans,  shall
(unless  they are held by a  sub-servicer  that shall,  as of the Closing  Date,
begin acting on behalf of the Master  Servicer  pursuant to a written  agreement
between such parties) be delivered by the Seller (or its agent) to the Purchaser
(or its designee) no later than the Closing Date.


                                       2
<PAGE>


     (d) The Seller's records will reflect the transfer of the Mortgage Loans to
the Purchaser as a sale.

     SECTION 3. Examination of Mortgage Loan Files and Due Diligence Review.

     The Seller shall reasonably  cooperate with any examination of the Mortgage
Files that may be undertaken by or on behalf of the Purchaser. The fact that the
Purchaser  has  conducted  or has failed to  conduct  any  partial  or  complete
examination  of the Mortgage Files and/or  Servicing  Files shall not affect the
Purchaser's  right to  pursue  any  remedy  available  in equity or at law for a
breach of the Seller's representations, warranties and covenants set forth in or
contemplated by Section 4.

     SECTION 4. Representations, Warranties and Covenants of the Seller.

     (a) Reserved.

     (b) The  Seller  Trustee,  as of the date  hereof,  hereby  represents  and
warrants to, and covenants with, the Purchaser that:

          (i) The Seller Trustee is duly organized, validly existing and in good
     standing under the laws of the United States, and is in compliance with the
     laws of each State in which any Mortgaged Property is located to the extent
     necessary to ensure the enforceability of each Mortgage Loan and to perform
     its obligations under this Agreement.

          (ii) The  execution  and  delivery  of this  Agreement  by the  Seller
     Trustee,  and  the  performance  and  compliance  with  the  terms  of this
     Agreement  by the Seller  Trustee,  will not violate  the Seller  Trustee's
     organizational  documents or constitute a default (or an event which,  with
     notice or lapse of time, or both,  would  constitute a default)  under,  or
     result in the breach of, any  material  agreement  or other  instrument  to
     which it is a party or which is applicable  to it or any of its assets,  in
     each case which  materially and adversely  affect the ability of the Seller
     Trustee to carry out the transactions contemplated by this Agreement.

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

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

          (vii) The Seller  Trustee  has not dealt with any  broker,  investment
     banker, agent or other person, other than the Purchaser,  the Underwriters,

     respective   affiliates,   that  may  be  entitled  to  any  commission  or
     compensation  in  connection  with  the sale of the  Mortgage  Loans by the
     Seller  to  the  Purchaser  or  the   consummation  of  any  of  the  other
     transactions contemplated hereby.

          (viii)  Neither the Seller Trustee nor anyone acting on its behalf has
     (A)  offered,  pledged,  sold,  disposed of or  otherwise  transferred  any

     security to any person in any manner,  (B) solicited any offer to buy or to
     accept a pledge,  disposition  or other  transfer of any Mortgage Loan, any
     interest in any Mortgage Loan or any other similar security from any person
     in any manner,  (C) otherwise  approached or negotiated with respect to any
     Mortgage  Loan,  any  interest in any  Mortgage  Loan or any other  similar
     security with any person in any manner,  (D) made any general  solicitation
     by means of general  advertising or in any other manner with respect to any
     Mortgage Loan,  any interest in any Mortgage Loan or any similar  security,
     or (E)  taken  any  other  action,  that  (in the  case of any of the  acts
     described in clauses (A) through (E) above) would constitute or result in a
     violation of the Securities Act or any state  securities law relating to or
     in  connection   with  the  issuance  of  the  Mortgage  Loans  or  require
     registration or  qualification  pursuant to the Securities Act or any state
     securities law of any Mortgage  Loan. In addition,  the Seller Trustee will
     not act, nor has it  authorized  or will it authorize any person to act, in
     any manner set forth in the  foregoing  sentence with respect to any of the
     Certificates or interests therein.

          (ix) No consent, approval,  authorization or order of, registration or
     filing with, or notice to, any governmental authority or court is required,
     under federal or state law (including, with respect to any bulk sale laws),
     for the execution,  delivery and performance of or compliance by the Seller
     Trustee with this Agreement,  or the  consummation by the Seller Trustee of
     any transaction contemplated hereby, other than (1) the filing or recording
     of  financing  statements,  instruments  of  assignment  and other  similar
     documents  necessary in connection with Seller's sale of the Mortgage Loans
     to

     qualification,  registration,  filing or notice  would not have a  material
     adverse  effect  on  the  performance  by the  Seller  Trustee  under  this
     Agreement.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)

     and the  performance and compliance with the terms of this Agreement by the

     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets.

          (iii) The Purchaser has the full power and authority to enter into and

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery by the Seller,  constitutes a valid,  legal and binding obligation

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

          (vi) No  litigation  is  pending  or,  to the best of the  Purchaser's
     knowledge,  threatened  against  the  Purchaser  which would  prohibit  the
     Purchaser  from entering into this  Agreement or, in the  Purchaser's  good
     faith and reasonable judgment, is likely to


                                       5
<PAGE>


     materially  and  adversely  affect  either the ability of the  Purchaser to
     perform its obligations under this Agreement or the financial  condition of
     the Purchaser.

          (vii) The Purchaser has not dealt with any broker,  investment banker,
     agent or other person, other than the Seller, the Underwriters, the Class X
     Certificate   Purchaser,   the  Initial  Purchasers  and  their  respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the transactions contemplated hereby.

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

     (b) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties  set forth above which  materially and adversely
affects the  interests of the Seller,  the party  discovering  such breach shall

<PAGE>


and in  contemplation of the assignment by the Purchaser to the Depositor of all

     Now, therefore,  in consideration of the premises and the mutual agreements
set forth herein, the parties agree as follows:

SECTION 1. Amendment of ML Trust Purchase Agreement.

     The parties hereto agree that, with respect to the Mortgage Loans only, the
ML Trust Purchase  Agreement is hereby amended to the extent that the provisions
of the ML Trust Purchase Agreement are inconsistent with this Agreement.

Section 2. Representations, Warranties and Covenants of the Seller.

     (a) The Seller  hereby makes,  as of February 9, 1999 (the "Closing  Date")
(or as of such other date specifically provided in the particular representation
or warranty),  to and for the benefit of the  Purchaser,  and its successors and
assigns  (including,  without  limitation,  the  Depositor,  the Trustee and the
holders of the  Certificates),  each of the  representations  and warranties set
forth in Exhibit B, with such  changes or  modifications  as may be permitted or
required by the Rating Agencies.

     (b) In addition,  the Seller, as of the date hereof,  hereby represents and
warrants to, and covenants with, the Purchaser that:

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

          (ii) The execution and delivery of this  Agreement by the Seller,  and
     the  performance  and  compliance  with the terms of this  Agreement by the
     Seller,  will  not  violate  the  Seller's   organizational   documents  or
     constitute a default (or an event which,  with notice or lapse of time,  or
     both,  would  constitute a default)  under, or result in the breach of, any
     material  agreement or other  instrument to which it is a party or which is
     applicable to it or any of its assets,  in each case which  materially  and
     adversely  affect the  ability of the Seller to carry out the  transactions
     contemplated by this Agreement.

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery  by  the  Purchaser,   constitutes  a  valid,  legal  and  binding
     obligation of the Seller, enforceable against the Seller in accordance with
     the  terms  hereof,  subject  to  (A)  applicable  bankruptcy,  insolvency,
     reorganization,  moratorium  and other laws  affecting the  enforcement  of
     creditors' rights generally,  (B) general principles of equity,  regardless
     of whether 


                                       2
<PAGE>


     such enforcement is considered in a proceeding in equity or at law, and (C)
     public policy considerations  underlying the securities laws, to the extent
     that such public  policy  considerations  limit the  enforceability  of the
     provisions of this  Agreement that purport to provide  indemnification  for
     securities laws liabilities.

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

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

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  the
     Class X Certificate Purchaser,  the Initial Purchasers and their respective
     affiliates,  that may be  entitled to any  commission  or  compensation  in
     connection  with the sale of the Mortgage Loans or the  consummation of any
     of the other transactions contemplated hereby.

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

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)
above which  materially and adversely  affects the interests of the Purchaser or
its  successors  or  assigns  or a  breach  of any of  the  representations  and
warranties  made  pursuant  to  subsection  (a) above and set forth in Exhibit B
which  materially  and  adversely  affects the value of any Mortgage Loan or the
interests  therein of the Purchaser or its  successors  and assigns  (including,
without   limitation  the  Depositor,   the  Trustee  and  the  holders  of  the
Certificates),  the party  discovering  such breach  shall give  prompt  written
notice to the other  party  hereto or if this  Agreement  is  assigned,  to such
assignee.  The  representations,  warranties  and  covenants  set  forth in this
Section  2(a)  shall  replace  and  amend  and  restate  in their  entirety  the
representations,  warranties  and  covenants  of the Seller set forth in Section
4.1(a) of the ML Trust  Purchase  Agreement  to the  extent  they  relate to the
Mortgage Loans.

SECTION 3. Representations, Warranties and Covenants of the Purchaser Trustee.

     (a) The Purchaser  Trustee,  as of the date hereof,  hereby  represents and
warrants to, and covenants with, the Seller that:

          (i) The Purchaser  Trustee is duly organized,  validly existing and in
     good standing under the laws of the United States.

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

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

          (iv)  This  Agreement,  assuming  due  authorization,   execution  and
     delivery by the Seller,  constitutes a valid,  legal and binding obligation
     of the Purchaser  Trustee,  enforceable  against the  Purchaser  Trustee in
     accordance  with the terms hereof,  subject to (A)  applicable  bankruptcy,
     insolvency,  reorganization,   moratorium  and  other  laws  affecting  the
     enforcement of creditors' rights generally,  and (B) general  principles of
     equity,   regardless  of  whether  such  enforcement  is  considered  in  a
     proceeding in equity or at law.

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

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

          (vii) The Purchaser Trustee has not dealt with any broker,  investment
     banker, agent or other person, other than the Seller, the Underwriters, the
     Class X Certificate Purchaser,  the Initial Purchasers and their respective
     affiliates, that may be entitled to any


                                       4
<PAGE>


     commission  or  compensation  in  connection  with the sale of the Mortgage
     Loans or the consummation of any of the transactions contemplated hereby.

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

     (b) The Purchaser hereby makes, as of the Closing Date (or as of such other
date specifically provided in the particular representation or warranty), to and
for the benefit of the Seller,  and its successor  and assigns,  with respect to
each Mortgage Loan each of the  representations  and  warranties set forth below
with such changes or modifications as may be permitted or required by the Rating
Agencies:

          (i) Immediately prior to the transfer thereof to the Depositor, to the
     Purchaser's  knowledge,  the Purchaser had whatever  title to such Mortgage
     Loan as was conveyed to it by Seller,  free and clear of any and all liens,
     encumbrances  and other  interests  on, in or to such  Mortgage Loan (other
     than, in certain cases, the right of a subservicer to directly service such
     Mortgage Loan).  Such transfer  validly assigns such title to such Mortgage
     Loan to the Depositor  free and clear of any pledge,  lien,  encumbrance or
     security interest executed by the Purchaser.

          (ii) The Purchaser  has full right and  authority to sell,  assign and
     transfer its interest in such Mortgage Loan.

          (iii) To the Purchaser's  knowledge,  the Purchaser has not, by act or
     omission, done anything that would materially impair the coverage under the
     lender's  title  insurance  policy  that  insures  the lien of the  related
     Mortgage.

          (iv) To the  Purchaser's  knowledge,  the Purchaser has not waived any
     material default, breach, violation or event of acceleration existing under
     the related Mortgage or Mortgage Note.

          (v) To the Purchaser's knowledge, there is no valid offset, defense or
     counterclaim to such Mortgage Loan.

          (vi) To the Purchaser's  knowledge,  the terms of the related Mortgage
     and the Mortgage Note have not been impaired,  waived,  altered or modified
     by the Purchaser in any material respect,  except as specifically set forth
     in the related Mortgage File.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties  set forth above which  materially and adversely
affects the


                                       5
<PAGE>


interests  of the Seller,  the party  discovering  such breach shall give prompt
written notice to the other party hereto.

SECTION 4. Repurchases.

     (a) Within 90 days of the earlier of  discovery or receipt of notice by the
Seller,  from either the  Purchaser  or any  successor or assign  thereof,  of a
Defect (as defined in the Pooling and  Servicing  Agreement  as in effect on the
Closing  Date) in respect of the Mortgage File for any Mortgage Loan or a breach
of any representation or warranty made pursuant to Section 2(a) and set forth in
Exhibit B (a "Breach"),  which Defect or Breach,  as the case may be, materially
and adversely affects the value of any Mortgage Loan or the interests therein of
the Purchaser or its successors and assigns (including,  without limitation, the
Depositor,  the Trustee and the holders of the  Certificates),  the Seller shall
cure such  Defect or Breach,  as the case may be, in all  material  respects  or
repurchase  the affected  Mortgage  Loan from the then  owner(s)  thereof at the
applicable  Purchase Price (as defined in the Pooling and Servicing Agreement as
in  effect  on the  Closing  Date) by  payment  of such  Purchase  Price by wire
transfer  of  immediately  available  funds to the  account  designated  by such
owner(s);  provided, however, that in lieu of effecting any such repurchase, the
Seller will be permitted to deliver a Qualifying Substitute Mortgage Loan and to
pay a cash amount equal to the applicable Substitution Shortfall Amount, subject
to the terms and conditions of the Pooling and Servicing  Agreement as in effect
on the Closing Date.

     If the Seller is notified of a Defect in any Mortgage File that corresponds
to  information  set forth in the  Mortgage  Loan  Schedule,  the  Seller  shall
promptly correct such Defect and provide a new, corrected Mortgage Loan Schedule
to the  Purchaser,  which  corrected  Mortgage Loan Schedule  shall be deemed to
amend and replace the existing Mortgage Loan Schedule for all purposes.

     (b)  Notwithstanding  Section  4(a),  within  60  days  of the  earlier  of
discovery or receipt of notice by the Seller,  from either the  Purchaser or any
successor  or assign  thereof,  that any  Mortgage  Loan does not  constitute  a
"qualified  mortgage" within the meaning of Section  860G(a)(3) of the Code, the
Seller shall repurchase such Mortgage Loan from the then owner(s) thereof at the
applicable  Purchase Price by payment of such Purchase Price by wire transfer of
immediately available funds to the account designated by such owner(s).

     In addition,  if, as of the Closing Date, any Mortgage Loan is secured by a
Mortgage that does not constitute a valid first lien upon the related  Mortgaged
Property,  including all  buildings  located  thereon and all fixtures  attached
thereto,  or if a Mortgage  is subject to  something  other than (A) the lien of
current  real  property  taxes  and  assessments  not yet due and  payable,  (B)
covenants,  conditions  and  restrictions,  rights of way,  easements  and other
matters of public record, (C) exceptions and exclusions specifically referred to
in the lender's title insurance  policy issued or, as evidenced by a "marked-up"
commitment,  to be  issued  in  respect  of such  Mortgage  Loan  and (D)  those
exceptions  set forth on Schedule  B-1 to Exhibit B hereto (the  exceptions  set
forth in the foregoing  clauses (A), (B), (C) and (D)  collectively,  "Permitted
Encumbrances"),  or if the insurer that issued the Title  Policy  referred to in
clause  (vi) of  Exhibit  B  hereto  in  respect  of any  Mortgage  Loan was not
qualified to do business in the state in which the related Mortgaged Property is
located,  and in either case such failure  materially and adversely  affects the
interests  of holder of  Certificates,  (any such failure  that  materially  and
adversely affects


                                       6
<PAGE>


the interests of holders of Certificates,  also a "Breach"), the Seller shall be
required, at its option, to either (i) cure such Breach in all material respects
or (ii)  repurchase  the  affected  Mortgage  Loan,  in each  case,  within  the
applicable  Permitted Cure Period.  If any such Breach is not corrected or cured
in all material respects within the applicable Permitted Cure Period, the Seller
shall, not later than the last day of such Permitted Cure Period, (i) repurchase
the affected  Mortgage Loan from the Purchaser or its assignee at the applicable
Purchase  Price or (ii) if  within  the  three-month  period  commencing  on the
closing date (or within the two-year  period  commencing  on the Closing Date if
the related  Mortgage  Loan is a  "defective  obligation"  within the meaning of
Section   860(a)(4)(B)(ii)   of  the  Code  and  Treasury   Regulation   Section
1.860G-2(f)),  at its  option,  replace  such  Mortgage  Loan with a  Qualifying
Substitute  Mortgage  Loan  and pay  any  corresponding  Substitution  Shortfall
Amount.  The Seller  agrees that any such  repurchase or  substitution  shall be
completed  in  accordance  with and subject to the terms and  conditions  of the
Pooling and Servicing Agreement.

     For purposes of the preceding  paragraph  only, the "Permitted Cure Period"
applicable  to any Defect or Breach in respect of any Mortgage Loan shall be the
90-day period  immediately  following the earlier of the discovery by the Seller
or receipt by the Seller of notice of such Defect or Breach, as the case may be;
provided that if such Defect or Breach,  as the case may be, cannot be corrected
or cured in all material  respects within such 90-day period,  but is reasonably
likely that such Defect or Breach,  as the case may be,  could be  corrected  or
cured  within 180 days of the earlier of  discovery by the Seller and receipt by
the  Seller of notice of such  Defect  or  Breach,  as the case may be,  and the
Seller is  diligently  attempting to effect such  correction  or cure,  then the
applicable Permitted Cure Period shall, with the consent of the Purchaser or its
assignee (which consent shall not be unreasonably  withheld), be extended for an
additional 90 days.

     (c) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan  contemplated by this Section 4, the then owner(s)  thereof shall tender or
cause to be tendered promptly to the Seller, upon delivery of a receipt executed
by the Seller,  the related  Mortgage File and Servicing File, and each document
that  constitutes  a part of the Mortgage  File that was endorsed or assigned to
the Purchaser or the Trustee shall be endorsed or assigned,  as the case may be,
to the Seller or its designee in the same manner.  The form and  sufficiency  of
all such instruments and certificates shall be the responsibility of the Seller.

     (d) This Section 4 provides the sole remedies  available to the  Purchaser,
and its successors and assigns (including,  without  limitation,  the Depositor,
the  Trustee  and the holders of the  Certificates)  respecting  any Defect in a
Mortgage File or any breach of any  representation  or warranty made pursuant to
Section 2(a) and set forth in Exhibit B, or in connection with the circumstances
described  in  Section  4(b).  If the  Seller  defaults  on its  obligations  to
repurchase any Mortgage Loan in accordance with Section 4(a) or 4(b) or disputes
its  obligation to repurchase  any Mortgage Loan in accordance  with either such
subsection,  the Purchaser or its successors and assigns may take such action as
is  appropriate  to enforce  such  payment or  performance,  including,  without
limitation,  the  institution and  prosecution of appropriate  proceedings.  The
Seller shall reimburse the Purchaser for all necessary and reasonable  costs and
expenses incurred in connection with such enforcement.  The remedies provided in
this Section 4


                                       7
<PAGE>


shall replace and amend and restate in their  entirety the provisions of Section
4.3 of the ML Trust Purchase Agreement.

SECTION 5. Conveyance of Mortgage Files.

     (a) In connection with the Purchaser's  assignment of the Mortgage Loans to
the Depositor  pursuant to the Mortgage Loan Purchase  Agreement,  the Purchaser
hereby  covenants  with the Seller that,  at least five (5) Business Days before
the Closing Date, it shall have delivered to and deposited with the Trustee, the
Mortgage  File  (as  described  on  Exhibit  B to  the  Mortgage  Loan  Purchase
Agreement)  for each  Mortgage Loan so assigned to the extent that such Mortgage
File was delivered to the Purchaser.  In the event Purchaser fails to so deliver
each such  Mortgage  File to the  Trustee,  the  Seller and its  successors  and
assigns  shall be  entitled  to pursue any rights or remedies in respect of such
failure as may be available under applicable law.

     (b) For the benefit of the Purchaser and its  successors  and assigns,  the
Seller  acknowledges and agrees that the Depositor  intends to cause the Trustee
to perform a limited review of the Mortgage Files relating to the Mortgage Loans
to enable the Trustee to confirm to the  Depositor on or before the Closing Date
that the  Mortgage  Note  referred to in clause (i) of Exhibit B of the Mortgage
Loan Purchase  Agreement has been  delivered to the Trustee with respect to each
such Mortgage File. If the Seller cannot deliver, or cause to be delivered as to
any Mortgage Loan,  the original  Mortgage Note, the Seller shall deliver a copy
or  duplicate  original  of such  Mortgage  Note,  together  with  an  affidavit
certifying that the original  thereof has been lost or destroyed.  If the Seller
cannot deliver, or cause to be delivered,  as to any Mortgage Loan, the original
or a copy of any of the  documents  and/or  instruments  referred  to in clauses
(ii), (iv), (viii), (xi)(A) and (xii) of Exhibit B of the Mortgage Loan Purchase
Agreement,  with evidence of recording thereon, solely because of a delay caused
by the public  recording or filing office where such document or instrument  has
been  delivered for  recordation  or filing,  or because such original  recorded
document  has been lost or  returned  from the  recording  or filing  office and
subsequently lost, as the case may be, the delivery requirements of this Section
5 shall be deemed to have  been  satisfied  as to such  missing  item,  and such
missing item shall be deemed to have been included in the related Mortgage File,
provided  that a copy  of such  document  or  instrument  (without  evidence  of
recording or filing  thereon,  but certified  (which  certificate  may relate to
multiple  documents and/or  instruments) by the Seller to be a true and complete
copy of the original thereof  submitted for recording or filing, as the case may
be) has been  delivered to the Trustee,  and either the original of such missing
document or instrument, or a copy thereof, with evidence of recording or filing,
as the  case  may  be,  thereon,  is  delivered  to or at the  direction  of the
Depositor or Trustee  within 180 days of the Closing Date (or within such longer
period  after the Closing  Date as the Trustee  (or such  subsequent  owner) may
consent to,  which  consent  shall not be  unreasonably  withheld so long as the
Seller has provided the Depositor or Trustee with evidence of such  recording or
filing,  as the case may be, or has  certified to the Depositor or Trustee as to
the  occurrence  of such  recording  or  filing,  as the case may be, and is, as
certified to the Trustee no less often than quarterly,  in good faith attempting
to obtain from the appropriate  county recorder's or filing office such original
or copy).

     (c) If the  Seller  cannot  deliver,  or cause to be  delivered,  as to any
Mortgage  Loan, the original or a copy of the related  lender's title  insurance
policy  referred to in clause (ix) of Exhibit B of the  Mortgage  Loan  Purchase
Agreement  solely  because  such policy has not yet been  issued, 


                                       8
<PAGE>


the delivery  requirements  of this Section 5 shall be deemed to be satisfied as
to such  missing  item,  and such  missing  item  shall be  deemed  to have been
included in the related Mortgage File, provided that the Seller has delivered to
the Trustee a commitment for title insurance  "marked-up" at the closing of such
Mortgage  Loan,  and the  Seller  shall  deliver to or at the  direction  of the
Depositor  or Trustee,  promptly  following  the receipt  thereof,  the original
related  lender's  title  insurance  policy (or a copy  thereof).  In  addition,
notwithstanding  anything to the contrary contained herein, if there exists with
respect to any group of  related  cross-collateralized  Mortgage  Loans only one
original of any document  referred to in Exhibit B of the Mortgage Loan Purchase
Agreement  covering all the Mortgage Loans in such group,  then the inclusion of
the original of such document in the Mortgage File for any of the Mortgage Loans
in such group shall be deemed an inclusion of such original in the Mortgage File
for each such Mortgage Loan.

     (d) As to each Mortgage Loan, the Seller shall be responsible for all costs
associated  with (i) the  recording  or  filing,  as the  case  may be,  of each
assignment  referred  to in clauses  (iii) and (v) of Exhibit B to the  Mortgage
Loan Agreement and each UCC-2 and UCC-3,  if any,  referred to in clause (xi)(B)
of Exhibit B to the Mortgage Loan Purchase  Agreement and (ii) the delivery of a
copy  of any  such  document  or  instrument  to the  Master  Servicer  promptly
following  its return to the Trustee or its  designee  after such  recording  or
filing; provided that the Seller shall not be responsible for actually recording
or filing any such document or instrument. If any such document or instrument is
lost or returned  unrecorded or unfiled, as the case may be, because of a defect
therein,  the  Seller  shall  promptly  prepare  or cause the  preparation  of a
substitute  therefor or cure or cause the curing of such defect, as the case may
be, and shall thereafter  deliver the substitute or corrected  document to or at
the  direction  of the  Depositor  or the Trustee for  recording  or filing,  as
appropriate, at the Seller's expense.

SECTION 6. Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,
incorporated herein by reference or contained in the certificates of officers of
the Seller submitted  pursuant hereto,  shall remain operative and in full force
and effect and shall survive delivery of the Mortgage Loans by the Seller to the
Purchaser or its designee.

SECTION 7. Costs.

     Costs relating to the transactions  contemplated hereby and in the Mortgage
Loan Purchase Agreement shall be borne by the Seller.

SECTION 8. Severability of Provisions.

     Any part, provision, representation, warranty or covenant of this Agreement
that is  prohibited  or  which  is held to be  void or  unenforceable  shall  be
ineffective  to the  extent  of such  prohibition  or  unenforceability  without
invalidating   the   remaining   provisions   hereof.   Any   part,   provision,
representation,  warranty or covenant of this  Agreement  that is  prohibited or
unenforceable  or  is  held  to be  void  or  unenforceable  in  any  particular
jurisdiction  shall,  as to such  jurisdiction,  be ineffective to the extent of
such  prohibition  or  unenforceability   without   invalidating  the  remaining
provisions  hereof,  and  any  such  prohibition  or   unenforceability  in  any
particular  jurisdiction  shall  not  invalidate  or render  unenforceable  such
provision in any other


                                       9
<PAGE>


jurisdiction.  To the extent  permitted by  applicable  law, the parties  hereto
waive any provision of law which prohibits or renders void or unenforceable  any
provision hereof.

SECTION 9. Counterparts.

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

SECTION 10. GOVERNING LAW.

     THIS AGREEMENT AND THE RIGHTS, DUTIES,  OBLIGATIONS AND RESPONSIBILITIES OF
THE PARTIES  HERETO SHALL BE GOVERNED IN  ACCORDANCE  WITH THE INTERNAL LAWS AND
DECISIONS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES
EXCEPT THAT THE PARTIES  HERETO INTEND THAT THE  PROVISIONS OF SECTION 5-1401 OF
THE NEW YORK GENERAL OBLIGATIONS LAW SHALL APPLY TO THIS AGREEMENT.

SECTION 11. Further Assurances.

     The Seller and the Purchaser agree to execute and deliver such  instruments
and take  such  further  actions  as the  other  party  may,  from time to time,
reasonably  request in order to  effectuate  the  purposes  and to carry out the
terms of this Agreement.

SECTION 12. Successors and Assigns.

     The rights and  obligations of the Seller under this Agreement shall not be
assigned  by the Seller  without  the prior  written  consent of the  Purchaser,
except that any person into which the Seller may be merged or  consolidated,  or
any  corporation  or other  entity  resulting  from any  merger,  conversion  or
consolidation to which the Seller is a party, or any person succeeding to all or
substantially  all of the business of the Seller,  shall be the successor to the
Seller hereunder.  The Purchaser has the right to assign its interest under this
Agreement, in whole or in part, to the Depositor and the Depositor shall, to the
extent of such  assignment,  succeed to the rights and obligations  hereunder of
the Purchaser.  Subject to the foregoing, this Agreement shall bind and inure to
the benefit of and be  enforceable  by the Seller and the  Purchaser,  and their
permitted successors and assigns.

SECTION 13. Amendments.

     No term or provision of this Agreement may be amended,  waived, modified or
in any way altered, unless such amendment, waiver, modification or alteration is
in writing and signed by a duly  authorized  officer of the party  against  whom
such amendment, waiver, modification or alteration is sought to be enforced.

                                    EXHIBIT A

                             MORTGAGE LOAN SCHEDULE


<PAGE>


                                    EXHIBIT B

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER
                     REGARDING THE INDIVIDUAL MORTGAGE LOANS


     With  respect to each  Mortgage  Loan,  the Seller  hereby  represents  and
warrants, as of the date hereinbelow specified or, if no such date is specified,
as of the Closing Date, except as set forth on Schedule B-1 hereto, that:

     (i) Ownership of Mortgage Loans.  Immediately prior to the transfer thereof
to the Depositor,  the Purchaser had good and  marketable  title to, and was the
sole owner and  holder of,  such  Mortgage  Loan,  free and clear of any and all
liens,  encumbrances  and other interests on, in or to such Mortgage Loan (other
than,  in certain  cases,  the right of a subservicer  to directly  service such
Mortgage Loan). Such transfer validly assigns ownership of such Mortgage Loan to
the  Depositor  free and clear of any  pledge,  lien,  encumbrance  or  security
interest.

     (ii) Authority to Transfer Mortgage Loans. The Purchaser has full right and
authority to sell,  assign and transfer such Mortgage  Loan. No provision of the
Mortgage  Note,  Mortgage or other loan document  relating to such Mortgage Loan
prohibits or restricts the Purchaser's right to assign or transfer such Mortgage
Loan.

     (iii) Mortgage Loan Schedule.  The information  pertaining to such Mortgage
Loan set forth in the Mortgage  Loan  Schedule  attached as Exhibit A hereto was
true and correct in all material respects as of the Cut-off Date.

     (iv) Payment Record.  Such Mortgage Loan was not as of the Cut-off Date for
such  Mortgage  Loan,  and has not been  during the  twelve-month  period  prior
thereto,  30 days or more  delinquent  in  respect of any debt  service  payment
required thereunder, without giving effect to any applicable grace period.

     (v) Permitted  Encumbrances.  The Permitted Encumbrances (as defined in the
Agreement of which this Exhibit B forms a part) do not materially interfere with
the security intended to be provided by the related Mortgage, the current use or
operation  of the  related  Mortgaged  Property  or the  current  ability of the
Mortgaged  Property to generate net operating  income  sufficient to service the
Mortgage Loan. If the Mortgaged  Property is operated as a nursing  facility,  a
hospitality property or a multifamily property, the Mortgage,  together with any
separate security agreement,  similar agreement and UCC financing statement,  if
any,  establishes  and creates a first  priority,  perfected  security  interest
(subject only to any prior purchase money security interest), to the extent such
security  interest  can be  perfected  by the  recordation  of a Mortgage or the
filing of a UCC  financing  statement,  in all  personal  property  owned by the
Mortgagor that is used in, and is reasonably  necessary to, the operation of the
related Mortgaged Property.

     (vi) Title  Insurance.  The lien of the  related  Mortgage is insured by an
ALTA lender's  title  insurance  policy ("Title  Policy"),  or its equivalent as
adopted in the applicable jurisdiction,  issued by a nationally recognized title
insurance company, insuring the originator of such Mortgage Loan, its successors
and assigns, as to the first priority lien of the Mortgage in the


<PAGE>


original  principal amount of the Mortgage Loan after all advances of principal,
subject only to Permitted  Encumbrances (or, if a title insurance policy has not
yet been issued in respect of the Mortgage  Loan, a policy meeting the foregoing
description is evidenced by a commitment for title insurance  "marked-up" at the
closing of such loan).  Each Title  Policy (or, if it has yet to be issued,  the
coverage to be  provided  thereby)  is in full force and  effect,  all  premiums
thereon have been paid and, to the Seller's  knowledge,  no material claims have
been made thereunder and no claims have been paid thereunder. Neither the Seller
nor the Purchaser has, by act or omission,  done anything that would  materially
impair the coverage under such Title Policy.  Immediately following the transfer
and  assignment of the related  Mortgage Loan to the Trustee,  such Title Policy
(or, if it has yet to be issued, the coverage to be provided thereby) will inure
to the benefit of the Trustee without the consent of or notice to the insurer.

     (vii) No Waivers by Seller of Material Defaults. Neither the Seller nor the
Purchaser  has  waived  any  material  default,  breach,  violation  or event of
acceleration existing under the related Mortgage or Mortgage Note.

     (viii) No Offsets,  Defenses or  Counterclaims.  There is no valid  offset,
defense or counterclaim to such Mortgage Loan.

     (ix)  Condition  of  Property;  Condemnation.  Except  as set  forth in any
engineering  report  prepared in connection with the origination of (or obtained
in  connection  with or otherwise  following the Seller's  acquisition  of) such
Mortgage Loan,  the related  Mortgaged  Property is, to the Seller's  knowledge,
free and clear of any damage  that would  materially  and  adversely  affect its
value as security for such Mortgage Loan. The Seller has no actual notice of the
commencement of a proceeding for the condemnation of all or any material portion
of the related Mortgaged Property.

     (x)  Compliance  with Usury Laws.  Such  Mortgage  Loan  complied  with all
applicable usury laws in effect at its date of origination.

     (xi) Full  Disbursement  of Mortgage  Loan  Proceeds.  The proceeds of such
Mortgage Loan have been fully  disbursed and there is no requirement  for future
advances thereunder.

     (xii) Enforceability.  The related Mortgage Note and Mortgage and all other
documents  and  instruments  evidencing,  guaranteeing,  insuring  or  otherwise
securing such Mortgage Loan have been duly and properly  executed by the parties
thereto,  and each is the  legal,  valid  and  binding  obligation  of the maker
thereof  (subject  to  any  non-recourse  provisions  contained  in  any  of the
foregoing  agreements and any  applicable  state  anti-deficiency  legislation),
enforceable  in accordance  with its terms,  except as such  enforcement  may be
limited by bankruptcy, insolvency,  reorganization,  receivership, moratorium or
other laws  relating to or affecting  the rights of creditors  generally  and by
general  principles  of  equity  (regardless  of  whether  such  enforcement  is
considered in a proceeding in equity or at law).

     (xiii) Insurance.  All improvements upon the related Mortgaged Property are
insured against loss by hazards of extended  coverage in an amount (subject to a
customary  deductible) at least equal to the lesser of the outstanding principal
balance  of such  Mortgage  Loan and 100% of the  full  replacement  cost of the
improvements located on such Mortgaged Property and the



                                      B-2
<PAGE>


related hazard insurance policy contains  appropriate  endorsements to avoid the
application  of  co-insurance  provisions  and  does  not  permit  reduction  in
insurance  proceeds for  depreciation.  If any portion of the related  Mortgaged
Property was, at the time of the  origination  of such Mortgage Loan, in an area
identified in the Federal Register by the Federal Emergency Management Agency as
having  special  flood  hazards,  and flood  insurance  was  available,  a flood
insurance policy meeting any requirements of the then current  guidelines of the
Federal  Insurance  Administration  is in  effect  with a  generally  acceptable
insurance carrier, in an amount representing coverage not less than the least of
(1) the  outstanding  principal  balance  of such  Mortgage  Loan,  (2) the full
insurable value of such Mortgaged Property,  (3) the maximum amount of insurance
available  under the National Flood  Insurance Act of 1968, as amended,  and (4)
100% of the  replacement  cost of the  improvements  located  on such  Mortgaged
Property.  In  addition,  the  Mortgage  requires  the  Mortgagor to maintain in
respect of the Mortgaged Property  comprehensive  general liability insurance in
amounts  generally  required  by the Seller,  and at least six months  rental or
business interruption insurance, and all such insurance required by the Mortgage
to be  maintained  is in full  force  and  effect.  Each such  insurance  policy
requires  prior  notice  to  the  holder  of  the  Mortgage  of  termination  or
cancellation,  and no such  notice has been  received,  including  any notice of
nonpayment of premiums, that has not been cured.

     (xiv) Environmental  Condition.  The related Mortgaged Property was subject
to one or more  environmental  site  assessments  (or an update of a  previously
conducted assessment), which was (were) performed on behalf of the Seller, or as
to which the related  report was delivered to the Seller in connection  with its
origination or acquisition of such Mortgage Loan; and the Seller, having made no
independent   inquiry  other  than  reviewing  the  resulting  report(s)  and/or
employing an environmental  consultant to perform the  assessment(s)  referenced
herein, has no knowledge of any material and adverse environmental conditions or
circumstance  affecting  such  Mortgaged  Property that was not disclosed in the
related  report(s).  The Seller has not taken any  action  with  respect to such
Mortgage  Loan  or  the  related  Mortgaged  Property  that  could  subject  the
Purchaser, or its successors and assigns in respect of the Mortgage Loan, to any
liability  under the  Comprehensive  Environmental  Response,  Compensation  and
Liability Act of 1980, as amended  ("CERCLA") or any other  applicable  federal,
state or local  environmental  law,  and the Seller has not  received any actual
notice of a material  violation of CERCLA or any  applicable  federal,  state or
local  environmental law with respect to the related Mortgaged Property that was
not disclosed in the related report.  The related  Mortgage or loan documents in
the related  Mortgage File requires the Mortgagor to comply with all  applicable
federal, state and local environmental laws and regulations.

     (xv) No  Cross-Collateralization  with Other Mortgage Loans.  Such Mortgage
Loan is not  cross-collateralized  with  any  mortgage  loan  that  will  not be
included in the Trust Fund.

     (xvi) Waivers and Modifications.  The terms of the related Mortgage and the
Mortgage  Note  have not been  impaired,  waived,  altered  or  modified  in any
material respect, except as specifically set forth in the related Mortgage File.

     (xvii) Taxes and Assessments.  There are no delinquent taxes, ground rents,
assessments for improvements or other similar  outstanding charges affecting the
related  Mortgaged  Property which are or may become a lien of priority equal to
or  higher  than  the  lien  of the  related  Mortgage.  For  purposes  of  this
representation and warranty, real property taxes and assessments


                                      B-3
<PAGE>


shall not be considered unpaid until the date on which interest and/or penalties
would be payable thereon.

     (xviii) Mortgagor's  Interest in Mortgaged Property.  Except in the case of
two  Mortgage  Loans as to which the  interest of the related  Mortgagor  in the
related  Mortgaged  Property  is in whole  or in part a  leasehold  estate,  the
interest of the related Mortgagor in the related Mortgaged  Property consists of
a fee simple estate in real property.

     (xix)  Whole  Loan.   Each  Mortgage  Loan  is  a  whole  loan  and  not  a
participation interest.

     (xx)  Valid  Assignment.  The  original  assignment  of  the  Mortgage,  in
recordable form, executed by the most recent assignee of record thereof prior to
the Trustee or, if none, by the  originator,  either in blank or in favor of the
Trustee (in such capacity)  included in the Mortgage File constitutes the legal,
valid and binding  assignment of such Mortgage from the relevant assignor to the
Trustee. The Assignment of Leases set forth in the Mortgage or separate from the
related  Mortgage and related to and delivered in connection  with each Mortgage
Loan establishes and creates a valid,  subsisting and, subject only to Permitted
Encumbrances,  enforceable  first  priority  lien and  first  priority  security
interest in the related Mortgagor's interest in all leases, subleases,  licenses
or other agreements  pursuant to which any person is entitled to occupy,  use or
possess all or any portion of the real property subject to the related Mortgage,
and each assignor  thereunder has the full right to assign the same. The related
assignment of any Assignment of Leases, not included in a Mortgage, executed and
delivered in favor of the Trustee is in recordable form and constitutes a legal,
valid and binding assignment, sufficient to convey to the assignee named therein
all of the assignor's right, title and interest in, to and under such Assignment
of Leases.

     (xxi) Escrows. All escrow deposits relating to such Mortgage Loan that are,
as of the Closing Date, required to be deposited with the mortgagee or its agent
have been so deposited.

     (xxii) No Mechanics' or Materialmen's  Liens. As of the date of origination
of such  Mortgage  Loan and, to the actual  knowledge  of the Seller,  as of the
Closing Date,  the related  Mortgaged  Property was and is free and clear of any
mechanics' and materialmen's liens or liens in the nature thereof which create a
lien prior to that  created by the  related  Mortgage,  except  those  which are
insured against by the Title Policy referred to in (vi) above.

     (xxiii) No Material  Encroachments.  To the  Seller's  knowledge  (based on
surveys and/or title  insurance  obtained in connection  with the origination of
such Mortgage Loan), as of the date of such origination, no improvement that was
included  for the  purpose of  determining  the  appraised  value of the related
Mortgaged  Property at the time of origination of such Mortgage Loan lay outside
the boundaries and building  restriction  lines of such property to any material
extent  (unless  affirmatively  covered by the title  insurance  referred  to in
paragraph (vi) above),  and no improvements on adjoining  properties  encroached
upon such Mortgaged Property to any material extent. To the Seller's  knowledge,
based upon opinions of counsel and/or other due diligence  customarily performed
by the Seller,  the  improvements  located on or forming part of such  Mortgaged
Property  comply  in all  material  respects  with  applicable  zoning  laws and
ordinances  (except to the extent that they may constitute legal  non-conforming
uses).


                                      B-4
<PAGE>


     (xxiv) Originator  Authorized.  To the extent required under applicable law
as of the Closing Date,  the  originator of such Mortgage Loan was authorized to
do  business in the  jurisdiction  in which the  related  Mortgaged  Property is
located at all times when it held the Mortgage  Loan to the extent  necessary to
ensure the enforceability of such Mortgage Loan.

     (xxv) No Material Default.  (A) To the Seller's knowledge,  there exists no
material default,  breach or event of acceleration under the related Mortgage or
Mortgage  Note,  and (B) the Seller has not received  actual notice of any event
(other than payments due but not yet delinquent)  that, with the passage of time
or with notice and the expiration of any grace or cure period,  would constitute
such a material  default,  breach or event of acceleration;  provided,  however,
that this  representation  and warranty  does not cover any  default,  breach or
event of acceleration that specifically pertains to any matter otherwise covered
or addressed by any other representation and warranty made by the Seller herein.

     (xxvi)  Inspection.  In connection  with the  origination or acquisition of
each Mortgage Loan, the Seller inspected or caused to be inspected the Mortgaged
Property.

     (xxvii) No Equity Participation or Contingent  Interest.  The Mortgage Loan
contains no equity  participation  by the  lender,  and does not provide for any
contingent or additional  interest in the form of participation in the cash flow
of the related Mortgaged Property, or for negative amortization.

     (xxviii) No Advances of Funds.  No holder of the Mortgage  Loan has, to the
Seller's knowledge,  advanced funds or induced,  solicited or knowingly received
any advance of funds from a party other than the owner of the related  Mortgaged
Property,  directly or indirectly, for the payment of any amount required by the
Mortgage Loan.

     (xxix)  Licenses,  Permits,  Etc. To the Seller's  knowledge,  based on due
diligence  customarily performed in the origination of comparable mortgage loans
by the Seller,  as of the date of  origination of the Mortgage Loan, the related
Mortgagor or operator of the related Mortgaged Property was in possession of all
material licenses,  permits and  authorizations  required by applicable laws for
the  ownership and  operation of the related  Mortgaged  Property as it was then
operated and if a related  Mortgaged  Property is improved by a skilled nursing,
congregate  care or assisted  living  facility,  the most recent  inspection  or
survey by governmental  authorities having  jurisdiction in connection with such
licenses,  permits and  authorizations  did not cite such Mortgaged Property for
material  violations  (which  shall  include  only  "Level  A"  (or  equivalent)
violations in the case of skilled nursing facilities) that had not been cured or
as to which a plan of correction  had not been submitted to and accepted by such
governmental  authorities.  To the extent such facility participates in Medicaid
or Medicare,  such facility is in  compliance in all material  respects with the
requirements of such program.

     (xxx) Servicing.  The servicing and collection  practices used with respect
to the Mortgage Loan have complied with applicable law in all material  respects
and are consistent  with the servicing  standard set forth in Section 3.01(a) of
the Pooling and Servicing Agreement.

     (xxxi) Customary Remedies.  The related Mortgage or Mortgage Note, together
with  applicable  state  law,  contains  customary  and  enforceable  provisions
(subject to the exceptions set


                                      B-5
<PAGE>


forth in  paragraph  (xii))  such as to render the rights  and  remedies  of the
holders  thereof  adequate  for the  practical  realization  against the related
Mortgaged  Property of the  principal  benefits of the  security  intended to be
provided thereby.

     (xxxii) Insurance and Condemnation  Proceeds. The related Mortgage provides
that insurance proceeds and condemnation proceeds will be applied for one of the
following purposes:  either to restore or repair the Mortgaged  Property,  or to
repay the  principal  of the  Mortgage  Loan,  or otherwise at the option of the
holder of the Mortgage.

     (xxxiii)  LTV.  The gross  proceeds  of such  Mortgage  Loan to the related
Mortgagor at origination did not exceed the  non-contingent  principal amount of
the Mortgage  Loan and either:  (A) such Mortgage Loan is secured by an interest
in real  property  having a fair market value (1) at the date the Mortgage  Loan
was originated at least equal to 80 percent of the original principal balance of
the Mortgage Loan or (2) at the Closing Date at least equal to 80 percent of the
principal balance of the Mortgage Loan on such date;  provided that for purposes
hereof,  the fair  market  value of the real  property  interest  must  first be
reduced  by (X) the  amount of any lien on the real  property  interest  that is
senior to the Mortgage Loan and (Y) 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 clauses (1) and (2) of this paragraph (xxxiii) shall be
made on a pro rata  basis in  accordance  with the  fair  market  values  of the
Mortgaged Properties securing such  cross-collateralized  Mortgage Loans; or (B)
substantially  all the  proceeds  of such  Mortgage  Loan were used to  acquire,
improve or protect the real property  which served as the only security for such
Mortgage  Loan  (other  than a recourse  feature  or other  third  party  credit
enhancement    within   the    meaning   of   Treasury    Regulations    Section
1.860G-2(a)(1)(ii)).

     (xxxiv)  LTV  and  Significant  Modifications.  If the  Mortgage  Loan  was
"significantly  modified" prior to the Closing Date so as to result in a taxable
exchange  under Section 1001 of the Code, it either (A) was modified as a result
of the default or  reasonably  foreseeable  default of such Mortgage Loan or (B)
satisfies  the  provisions  of  either  clause  (A)(1)  of  paragraph   (xxxiii)
(substituting  the date of the last such  modification for the date the Mortgage
Loan was  originated)  or clause  (A)(2) of paragraph  (xxxiii),  including  the
proviso thereto.

     (xxxv) [Reserved]

     (xxxvi) Litigation. To the Seller's actual knowledge,  there are no pending
actions,  suits or proceedings by or before any court or governmental  authority
against or affecting  the related  Mortgagor or the related  Mortgaged  Property
that, if determined  adversely to such  Mortgagor or Mortgaged  Property,  would
materially  and  adversely  affect the value of the  Mortgaged  Property  or the
ability of the  Mortgagor to pay  principal,  interest or any other  amounts due
under such Mortgage Loan.

     (xxxvii) Leasehold Estate.  Each Mortgaged Property consists of the related
Mortgagor's fee simple  interest in real estate or the related  Mortgage Loan is
secured in whole or in part by the interest of the Mortgagor as a lessee under a
ground lease of the  Mortgaged  Property (a "Ground  Lease").  Any Mortgage Loan
that is secured by the interest of the Mortgagor under a Ground Lease may or may
not be secured by the related fee interest in such


                                      B-6
<PAGE>


Mortgaged Property (the "Fee Interest").  If a Mortgage Loan is secured in whole
or in part by a Ground  Lease,  either (1) the ground  lessor's  Fee Interest is
subordinated  to the lien of the  Mortgage  or (2) the  following  apply to such
Ground Lease:

     (A)  To  the  actual  knowledge  of the  Seller,  based  on  due  diligence
          customarily  performed in the origination of comparable mortgage loans
          by the Seller,  such Ground Lease or a memorandum  thereof has been or
          will be duly  recorded;  such Ground  Lease (or the  related  estoppel
          letter or lender  protection  agreement between the Seller and related
          lessor) permits the interest of the lessee thereunder to be encumbered
          by the related Mortgage;  and there has been no material change in the
          payment  terms of such  Ground  Lease  since  the  origination  of the
          related   Mortgage  Loan,  with  the  exception  of  material  changes
          reflected  in  written  instruments  that  are a part  of the  related
          Mortgage File;

     (B)  The lessee's interest in such Ground Lease is not subject to any liens
          or  encumbrances  superior to, or of equal  priority with, the related
          Mortgage,  other than the ground  lessor's  related fee  interest  and
          Permitted Encumbrances;

     (C)  The  Mortgagor's  interest in such Ground Lease is  assignable  to the
          Purchaser and its  successors  and assigns upon notice to, but without
          the  consent  of,  the  lessor  thereunder  (or,  if such  consent  is
          required,  it has been obtained prior to the Closing Date) and, in the
          event that it is so assigned,  is further  assignable by the Purchaser
          and its successors and assigns upon notice to, but without the need to
          obtain the consent of, such lessor;

     (D)  Such  Ground  Lease is in full  force and  effect,  and the Seller has
          received no notice that an event of default has  occurred  thereunder,
          and, to the Seller's actual knowledge, there exists no condition that,
          but for the  passage of time or the giving of notice,  or both,  would
          result in an event of default under the terms of such Ground Lease;

     (E)  Such Ground Lease, or an estoppel letter or other agreement,  requires
          the lessor  under such  Ground  Lease to give notice of any default by
          the lessee to the  mortgagee,  provided that the mortgagee  under such
          Mortgage  Loan has  provided  the  lessor  with  notice of its lien in
          accordance  with the provisions of such Ground Lease,  and such Ground
          Lease, or an estoppel letter or other agreement, further provides that
          no notice of  termination  given under such Ground  Lease is effective
          against  the  mortgagee  unless  a  copy  has  been  delivered  to the
          mortgagee;

     (F)  The  mortgagee  under such  Mortgage  Loan is  permitted a  reasonable
          opportunity  (including,  where  necessary,  sufficient  time  to gain
          possession  of the interest of the lessee under such Ground  Lease) to
          cure any default under such Ground  Lease,  which is curable after the
          receipt of notice of any such  default,  before the lessor  thereunder
          may terminate such Ground Lease;


                                      B-7
<PAGE>


     (G)  Such  Ground  Lease has an  original  term  (including  any  extension
          options  set  forth  therein)  which  extends  not less than ten years
          beyond the Stated Maturity Date of the related Mortgage Loan;

     (H)  Under the terms of such Ground Lease and the related  Mortgage,  taken
          together,  any related  insurance  proceeds other than in respect of a
          total or substantially total loss or taking, will be applied either to
          the  repair or  restoration  of all or part of the  related  Mortgaged
          Property,  with the  mortgagee  under such  Mortgage Loan or a trustee
          appointed by it having the right to hold and disburse such proceeds as
          the repair or  restoration  progresses  (except in such cases  where a
          provision  entitling  another party to hold and disburse such proceeds
          would  not  be  viewed  as  commercially  unreasonable  by  a  prudent
          commercial  mortgage  lender),  or to the  payment of the  outstanding
          principal  balance of the  Mortgage  Loan  together  with any  accrued
          interest thereon;

     (I)  Such Ground Lease does not impose any restrictions on subletting which
          would be viewed, as of the date of origination of the related Mortgage
          Loan,  as  commercially  unreasonable  by the Seller;  and such Ground
          Lease contains a covenant that the lessor thereunder is not permitted,
          in the  absence of an uncured  default,  to  disturb  the  possession,
          interest or quiet enjoyment of any subtenant of the lessee,  or in any
          manner,  which would materially adversely affect the security provided
          by the related Mortgage; and

     (J)  Such Ground Lease, or an estoppel  letter or other agreement  requires
          the lessor to enter into a new lease in the event of a termination  of
          the  Ground  Lease by reason of a default by the  Mortgagor  under the
          Ground Lease, including, rejection of the ground lease in a bankruptcy
          proceeding.

     (xxxviii)  Deed of Trust.  If the related  Mortgage  is a deed of trust,  a
trustee,  duly  qualified  under  applicable  law to serve as such,  is properly
designated and serving under such Mortgage.

     (xxxix)  Lien  Releases.  Except in cases  where  either (a) a release of a
portion  of the  Mortgaged  Property  was  contemplated  at  origination  of the
Mortgage  Loan and such  portion was not  considered  material  for  purposes of
underwriting   the  Mortgage  Loan  or  (b)  release  is  conditioned  upon  the
satisfaction of certain underwriting and legal requirements and the payment of a
release price, the related Mortgage Note or Mortgage does not require the holder
thereof to release all or any portion of the Mortgaged Property from the lien of
the related  Mortgage  except upon payment in full of all amounts due under such
Mortgage Loan.



                                      B-8
<PAGE>


     (xl) Junior Liens. The Mortgage Loan does not permit the related  Mortgaged
Property to be  encumbered  by any lien junior to or of equal  priority with the
lien of the related  Mortgage  (excluding any lien relating to another  Mortgage
Loan that is  cross-collateralized  with such  Mortgage  Loan) without the prior
written  consent  of the  holder  thereof or the  satisfaction  of debt  service
coverage or similar conditions specified therein.

     (xli) Mortgagor Bankruptcy. To the Seller's knowledge, the Mortgagor is not
a debtor in any state or federal bankruptcy or insolvency proceeding.

     (xlii) Due  Organization  of  Mortgagors.  As of the date of origination of
each  Mortgage,  each related  Mortgagor  which is not a natural person was duly
organized and validly existing under the laws of the state of its jurisdiction.

     (xliii)  Due-On-Sale.   The  Mortgage  Loan  contains  provisions  for  the
acceleration  of the payment of the unpaid  principal  balance of such  Mortgage
Loan if,  without  complying  with the  requirements  of such Mortgage Loan, the
related Mortgaged Property,  or any controlling interest therein, is directly or
indirectly transferred or sold.

     (xliv) Single  Purpose  Entity.  The Mortgagor is an entity,  other than an
individual,   whose  organizational  documents  or  the  related  Mortgage  Loan
Documents provide substantially to the effect that the Mortgagor:  (A) is formed
or organized  solely for the purpose of owning and  operating one or more of the
Mortgaged  Properties  securing  the Mortgage  Loans,  (B) may not engage in any
business unrelated to such Mortgaged Property or Mortgaged Properties,  (C) does
not have any  material  assets  other than those  related to its interest in and
operation of such Mortgage Property or Mortgaged  Properties,  (D) may not incur
indebtedness  other than as permitted by the related  Mortgage or other Mortgage
Loan  Documents,  (E) has its own books and records  separate and apart from any
other  person,  and (F) holds itself out as a legal  entity,  separate and apart
from any other person.

     (xlv) Defeasance  Provisions.  Any Mortgage Loan which contains a provision
for any defeasance of mortgage collateral either (A) requires the consent of the
holder of the Mortgage Loan to any defeasance,  or (B) permits defeasance (i) no
earlier  than two years  after the  Closing  Date (as defined in the Pooling and
Servicing  Agreement,  dated as of August 1,  1998),  (ii) only with  substitute
collateral  constituting  "government  securities"  within the meaning of Treas.
Reg. ss.  1.860G-2(a)(8)(i),  and (iii) only to facilitate  the  disposition  of
mortgage real property and not as a part of an  arrangement to  collateralize  a
REMIC offering with obligations that are not real estate mortgages.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Exhibit B shall survive delivery of the respective  Mortgage Files
to the  Purchaser,  the  Depositor  and/or the  Trustee  and shall  inure to the
benefit of the  Purchaser,  and its successors  and assigns  (including  without
limitation  the  Depositor,  the Trustee  and the holders of the  Certificates),
notwithstanding any restrictive or qualified endorsement or assignment.

<PAGE>

                            INDEMNIFICATION AGREEMENT

                    GMAC Commercial Mortgage Securities, Inc.
               Mortgage Pass-Through Certificates, Series 1999-C1

     WHEREAS,  GMAC  Commercial  Mortgage  Corporation  ("GMACCM")  sold certain
mortgage loans (the "Mortgage  Loans") to Restructured  Asset  Certificates with
Enhanced  Returns,  Series 1998-ML Trust (the "ML Trust")  pursuant to a certain
Mortgage Loan Purchase Agreement (the "ML Trust Purchase  Agreement"),  dated as
of June 30, 1998.

     WHEREAS,  ML Trust  intends to sell the Mortgage  Loans to GMAC  Commercial
Mortgage  Securities,  Inc.  (the  "Depositor")  and the  Depositor  intends  to
transfer the Mortgage  Loans,  together with other  multifamily  and  commercial
mortgage loans to a trust fund (the "Trust Fund") to be formed by the Depositor,
beneficial  ownership  of  which  will be  evidenced  by a  series  of  mortgage
pass-through  certificates (the "Certificates").  The Trust Fund will be created
and  the  Certificates  will be  issued  pursuant  to a  pooling  and  servicing
agreement  to be dated as of  February  1,  1999  (the  "Pooling  and  Servicing
Agreement"),  among the Depositor, as depositor,  GMACCM, as master servicer and
special servicer, and Norwest Bank Minnesota,  National Association,  as trustee
(in such  capacity,  the  "Trustee").  Capitalized  terms not otherwise  defined
herein  have  the  meanings  assigned  to  them  in the  Pooling  and  Servicing
Agreement.

     WHEREAS, GMACCM and ML Trust, in connection with the transactions described
above, entered into a Supplemental Agreement,  dated as of February 2, 1999 (the
"Supplemental  Agreement"),  which  amended  and  supplemented  certain  of  the
provisions  of the ML Trust  Purchase  Agreement  as they relate to the Mortgage
Loans in order to facilitate such transactions.

     WHEREAS,  ML Trust will assign to the  Depositor  all of ML Trust's  right,
title and interest in and to the Supplemental Agreement.

     WHEREAS,  as a condition  precedent to the consummation of the transactions
described above,  including,  without  limitation,  the receipt by ML Trust of a
ratable portion of the proceeds of the sale of the Certificates,  it is required
that Lehman ALI, Inc.  ("Lehman"),  indemnify  GMACCM for any losses relating to
the  breach  of  certain  representations  and  warranties  of ML  Trust  in the
Supplemental Agreement.

     NOW THEREFORE,  in consideration of the agreements  contained  herein,  and
other valuable consideration, Lehman and GMACCM agree as follows:

     1.  Indemnification  and  Contribution.  (a) Lehman agrees to indemnify and
hold harmless  GMACCM and each person who controls  GMACCM within the meaning of
either the  Securities  Act of 1933,  as amended (the  "Securities  Act") or the
Securities  Exchange Act of 1934, as amended (the "Exchange  Act"),  against any
and all losses,  claims,  damages or liabilities,  joint or several, to which it
may become subject  insofar as such losses,  claims,  damages or liabilities (or
actions in respect  thereto) arise out of or are based upon the breach of any of
ML Trust's representations or warranties contained in any of clauses (i) or (ii)
of Section


<PAGE>


3(b) of the  Supplemental  Agreement.  This indemnity will be in addition to any
liability which ML Trust may otherwise have.

     (b) Promptly after receipt by an indemnified  party under this Section 1 of
notice of the  commencement  of any action,  such  indemnified  party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 1, notify the indemnifying party in writing of the commencement thereof,
but the  omission  so to notify  the  indemnifying  party will not  relieve  the
indemnifying party from any liability which it may have to any indemnified party
otherwise than under this Section 1. In case any such action is brought  against
any indemnified party and it notifies the indemnifying party of the commencement
thereof,  the indemnifying party will be entitled to participate therein, and to
the extent  that it may elect by written  notice  delivered  to the  indemnified
party promptly after receiving the aforesaid notice from such indemnified party,
to assume the defense  thereof,  with counsel  reasonably  satisfactory  to such
indemnified  party;  provided that, if the defendants in any such action include
both the indemnified party and the indemnifying  party and the indemnified party
or parties  shall have  reasonably  concluded  that there may be legal  defenses
available to it or them and/or other  indemnified  parties  which are  different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate  counsel to assert such
legal  defenses  and to otherwise  participate  in the defense of such action on
behalf of such  indemnified  party or parties.  Upon  receipt of notice from the
indemnifying  party to such  indemnified  party of its election so to assume the
defense of such action and approval by the  indemnified  party of counsel (which
approval shall not be reasonably  withheld),  the indemnifying party will not be
liable to such indemnified  party for expenses incurred by the indemnified party
in connection with the defense  thereof unless (i) the  indemnified  party shall
have  employed  separate  counsel  in  connection  with the  assertion  of legal
defenses in accordance  with the proviso to the immediately  preceding  sentence
(it being understood,  however,  that the indemnifying party shall not be liable
for the expenses of more than one separate counsel in each  jurisdiction),  (ii)
the indemnifying party shall not have employed counsel  reasonably  satisfactory
to the indemnified  party to represent the indemnified party within a reasonable
time after notice of commencement of the action or (iii) the indemnifying  party
has authorized in writing the employment of counsel for the indemnified party at
the expense of the  indemnifying  party; and except that, if clause (i) or (iii)
is applicable,  such liability shall be only in respect of the counsel  referred
to in such clause (i) or (iii).

     (c) If the  indemnification  provided  for in this  Section I shall for any
reason be unavailable to, or insufficient to hold harmless an indemnified  party
in accordance with its terms to an indemnified  party under this Section 1, then
Lehman on the one hand and GMACCM on the other  shall  contribute  to the amount
paid or payable by such  indemnified  party as a result of the  losses,  claims,
damages or liabilities  (or actions in respect of) referred to in subsection (a)
or (b) above, in such proportion as is appropriate to reflect the relative fault
of ML Trust,  on the one hand, and GMACCM on the other,  in connection  with the
breach of  representation  and warranty  that  resulted in such losses,  claims,
damages or liabilities,  as well as any other relevant equitable considerations.
The relative  fault shall be  determined  by reference  to, among other  things,
whether the breach of representation or warranty relates to information supplied
by ML Trust or GMACCM and the parties'  relative  intent,  knowledge,  access to
information and opportunity to correct or prevent such breach of  representation
or warranty.  Lehman and GMACCM agree that it would not be just and equitable if
contributions  pursuant to this subsection (c) were to be


                             
<PAGE>


determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable  considerations referred to herein. The amount
paid or  payable  by an  indemnified  party as a result of the  losses,  claims,
damages or liabilities (or actions in respect thereof)  referred to in the first
sentence  of this  subsection  (c) shall be deemed to include any legal or other
expenses  reasonably  incurred  by such  indemnified  party in  connection  with
investigating  or defending  against any action or claim which is the subject of
this  Section  1,  subject  to  the  limitations  therein  provided  under  this
subsection  (c). No person  guilty of fraudulent  misrepresentation  (within the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution  from  any  person  who  was not  also  guilty  of such  fraudulent
misrepresentation.

     2. Notices. All demands,  notices and communications  hereunder shall be in
writing and shall be deemed to have been duly given if  personally  delivered to
or mailed,  by registered mail,  postage  prepaid,  by overnight mail or courier
service,  or transmitted by facsimile and confirmed by a similar mailed writing,

may designate in writing to GMACCM.

     3.  Severability.  The  invalidity or  unenforceability  of any one or more
phrases,  sentences,  paragraphs or Sections in this Agreement  shall not affect
the validity or  enforceability  of the remaining  portions of this Agreement or
any part thereof.

     4.  Definitions.  Capitalized  terms used and not otherwise  defined herein
shall have the meaning set forth in the Pooling and Servicing Agreement.

     5. Miscellaneous.  This Indemnification Agreement shall be governed by, and
construed  in  accordance  with,  the  laws  of  the  State  of New  York.  This
Indemnification  Agreement shall inure to the benefit of and be binding upon the
parties  hereto and their  successors  and assigns and the  controlling  persons
referred  to herein,  and no other  person  shall  have any right or  obligation
hereunder.  Neither this  Indemnification  Agreement  nor any term hereof may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing  signed by the party  against whom  enforcement  of the change,  waiver,
discharge  or  termination  is sought.  This  Indemnification  Agreement  may be
executed in counterparts,  each of which when so executed and delivered shall be
considered an original,  and all such counterparts  shall constitute one and the
same  instrument.  Any person into which Lehman may be merged,  consolidated  or
converted,  or any  corporation  resulting from any merger or  consolidation  to
which  Lehman  shall be a party,  or any person  succeeding  to the  business of
Lehman, shall be the successor of Lehman, as the case may be, hereunder, without

the parties hereto, anything herein to the contrary notwithstanding.

Agreement  to be duly  executed  by  their  respective  officers  hereunto  duly
