entire beneficial  ownership interest in, the assets of a trust fund (the "Trust
Fund")  consisting  primarily of a pool (the "Mortgage  Pool") of commercial and
multifamily mortgage loans (the "Mortgage Loans"), having as of their respective
cut-off  dates  (the  "Cut-off  Dates"),   an  aggregate  principal  balance  of
$974,502,237  (the  "Initial  Pool  Balance"),  after  taking  into  account all

99.1,  between  GMACCM as seller and the Depositor as  purchaser.  The Depositor

Corporation  ("GACC")  pursuant to a mortgage loan purchase  agreement dated May

Servicing Agreement

     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 June 1, 1999 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 Mayer, Brown & Platt at 10:00 a.m.,
New York City time, on June 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

          "THE  INFORMATION   HEREIN  HAS  BEEN  PROVIDED  SOLELY  BY  [NAME  OF
          [APPLICABLE] UNDERWRITER].  NEITHER THE ISSUER OF THE CERTIFICATES NOR
          ANY OF ITS AFFILIATES MAKES ANY  REPRESENTATION  AS TO THE ACCURACY OR
          COMPLETENESS OF THE  INFORMATION  HEREIN.  THE  INFORMATION  HEREIN IS
          PRELIMINARY  AND  WILL  BE  SUPERSEDED  BY THE  APPLICABLE  PROSPECTUS
          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

                                       7

<PAGE>

          PREPARED BY THE UNDERWRITERS,] SUPERSEDES ALL INFORMATION CONTAINED IN
          ANY COLLATERAL  TERM SHEETS  RELATING TO THE MORTGAGE POOL  PREVIOUSLY
          PROVIDED BY [NAME OF [APPLICABLE] UNDERWRITER]."

     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 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

                                       8

<PAGE>

     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  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.

                                       9

          (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.

                                       10

<PAGE>


     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.

     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  PriceWaterhouseCoopers,  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

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:

          (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. (1)

                                       12

<PAGE>



          (c) 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 Pooling and Servicing  Agreement and this  Agreement and that,
     to the best of his 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.

     6.4 The  Underwriters  shall have  received the opinions of Mayer,  Brown &
Platt,  special  counsel for the Company and GMACCM,  dated the Closing Date and
substantially  to the effect set forth in Exhibits  A-1 and A-2,  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.

     6.5 The  Underwriters  shall have  received  from their  counsel an opinion
dated the Closing  Date in form and  substance  reasonably  satisfactory  to the
Underwriters.

     6.6 The  Underwriters  shall  have  received  from  PriceWaterhouseCoopers,
L.L.P.,  certified  public  accountants,  (a) a letter dated the date hereof and
reasonably  satisfactory  in form and  substance to the  Underwriters  and their
counsel,  to the effect that they have performed certain  specified  procedures,
all of which have 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"  agrees with the records of the Company and the GMACCM excluding
any questions of legal  interpretation  and (b) the letter prepared  pursuant to
Section 5.9 hereof.

     6.7 The respective  classes of  Underwritten  Certificates  shall have been
rated as set forth on Schedule I.

     6.8 The Underwriters  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  representations  and  warranties
made by, and on  certificates  or other  documents  furnished by officers and/or
authorized  representatives  of,  parties to this  Agreement and the Pooling and
Servicing  Agreement and on  certificates  furnished by public  officials.  Such
opinion  may  assume  the  due  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

                                       13

<PAGE>

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.

     6.9 The Underwriters shall have received from Mayer, Brown & Platt, 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 on Schedule I hereto.

     6.10 The  Underwriters  shall have  received  from counsel to each Mortgage
Loan Seller, the opinions  substantially to the effect set forth in Exhibit D-3A
and D-3B of the GMACCM Mortgage Loan Purchase Agreement,  Exhibit C-3 of each of
the Purchase Agreements.

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

     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  Loans  contained in the Prospectus  Supplement  under the headings
"Summary--The Mortgage Pool," "Risk Factors" and/or "Description of the Mortgage
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

                                       14

<PAGE>

regarding  GMACCM or the Mortgage Loans  contained in the Prospectus  Supplement
under  the  headings   "Summary--The   Mortgage  Pool,"  "Risk  Factors"  and/or
"Description  of the Mortgage 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 or
Term  Sheet  Diskettes  that are  caused by errors  in the Pool  Information  or
information contained in the Term Sheet Master Tape; 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  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

                                       15

<PAGE>

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.

                                       16

<PAGE>


     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

                                       17

<PAGE>

Underwritten  Certificates,  this Agreement will terminate  without liability to
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,

                                  June 9, 1999


To:  Persons listed on Annex A hereto

GMAC Commercial Mortgage Securities, Inc., Mortgage
Pass-Through Certificates, Series 1999-C2

Ladies and Gentlemen:

     We have acted as special  counsel to GMAC Commercial  Mortgage  Securities,
Inc. (the  "Company") and GMAC  Commercial  Mortgage  Corporation  ("GMACCM") in
connection   with  the   issuance  by  the  Company  of  Mortgage   Pass-Through
Certificates,   Series  1999-C2  (the   "Certificates"),   evidencing  undivided
interests  in a trust fund (the "Trust  Fund")  consisting  primarily of certain
mortgage  loans (the  "Mortgage  Loans"),  pursuant to the Pooling and Servicing
Agreement,  dated as of June 1, 1999 (the  "Pooling and  Servicing  Agreement"),
among the Company as depositor,  GMACCM as master servicer and special servicer,
LaSalle Bank National  Association as trustee (the  "Trustee") and ABN AMRO Bank
N.V., as fiscal agent (the "Fiscal Agent").

     Certain of the  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 May  25,  1999  (the  "GMACCM  Mortgage  Loan  Purchase
Agreement"),  between the Company and the Seller.  Certain of the Mortgage Loans
were purchased by the Company from Column Financial,  Inc.  ("Column")  pursuant
to,  and  for  the  consideration  described  in,  the  Mortgage  Loan  Purchase
Agreement,  dated May 25, 1999 (the "Column  Mortgage Loan Purchase  Agreement")
between the Company and Column.  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 May 25, 1999 (the "GACC  Mortgage Loan Purchase  Agreement"),  between the
Company  and  GACC.  Mortgage  Company  ("GSMC"),   pursuant  to,  and  for  the
consideration  described in, the Mortgage Loan Purchase  Agreement,  dated as of
May 25, 1999 (the "GSMC Mortgage Loan Purchase Agreement"),  between the Company
and GSMC.

     The Company has sold the Class X, Class A-1,  Class A-2,  Class B, Class C,
Class D, Class E, Class F and Class G to Donaldson, Lufkin & Jenrette Securities
Corporation,  Deutsche  Bank  Securities  Inc. and  Goldman,  Sachs & Co. as the
underwriters (the "Underwriters") named in the Underwriting Agreement, dated May
25, 1999 (the "Underwriting Agreement"),  among the Company, the Seller, and the
Underwriters.  The Company  sold the Class H, Class J, Class K, Class L, Class M
and Class N Certificates to Commercial Asset Trading Inc.  ("CATI")  pursuant to
the  Certificate  Purchase  Agreement,  dated  May 25,  1999  (the  "Certificate
Purchase  Agreement"),  between the Company and CATI. The Company sold the Class
R-I,  Class R-II

                                     A-1-1

<PAGE>

and Class R-III  Certificates  to Credit  Suisse First Boston  Corporation.  The
Certificate Purchase Agreement,  the Underwriting Agreement, the GMACCM Mortgage
Loan Purchase Agreement,  the Column Mortgage Loan Purchase Agreement,  the GACC
Mortgage Loan Purchase Agreement,  the GSMC Mortgage Loan Purchase Agreement and
the Pooling and Servicing  Agreement are referred to herein  collectively as the
"Agreements."  Capitalized  terms not defined herein have the meanings set forth
in the Agreements.

     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 has filed 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 May 25, 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
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."

     In connection  with  rendering  this opinion  letter,  we have examined the
Agreements and such other documents as we have deemed  necessary.  As to matters
of fact, we have examined and relied upon the accuracy of the representations of
parties  to  the  Agreements   contained  therein  and,  where  we  have  deemed
appropriate, separate additional representations or certifications of parties to
the  Agreements,   their  respective  officers  and  representatives  or  public
officials.  In  rendering  this  opinion  letter,  we have also  assumed (i) the
authenticity of all documents  submitted to us as originals,  the genuineness of
all signatures,  the legal capacity of natural persons and the conformity to the
originals of all documents  submitted to us as copies,  (ii) except as expressly
addressed  below,  the  due  authorization,  execution  and  delivery,  and  the
necessary power with respect thereto,  and the enforceability of such documents,
(iii) the  conformity to the  requirements  of the  Agreements,  of the Mortgage
Notes, the Mortgages and other documents  delivered or caused to be delivered to
the Trustee by or on behalf of the Company,  (iv) the performance by all parties
to the  Agreements  in  accordance  with their  covenants  and  agreements  made
therein,  and  (v)  that  there  is not  any  other  agreement  that  materially
supplements or otherwise modifies the agreements expressed in the Agreements.

     In rendering this opinion letter, we do not express any opinion  concerning
any law other than the law of the State of New York,  the  corporate  law of the
State of Delaware  and the federal law of the United  States,  nor do we 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 and, in each case,  as in existence  on the date  hereof.  In
rendering  the opinions set forth below,  as to matters  governed by the laws of
the  Commonwealth  of  Pennsylvania  or

                                     A-1-2

<PAGE>

other laws that may be  applicable  to the Company  and  GMACCM,  we have relied
without  independent  investigation on the opinion letter of Maria Corpora-Buck,
Esq.,  general counsel to the Company and GMACCM,  dated the date hereof, a copy
of which is annexed  hereto.  In addition,  in rendering  the opinions set forth
below, as to matters governed by the laws of the State of California that may be
applicable to GMACCM, we have relied on the opinion letter of Severson & Werson,
special California counsel to GMACCM,  dated the date hereof, a copy of which is
annexed  hereto.  To the extent  that we have  relied on the  foregoing  opinion
letters,  the  opinions  set forth  below are  subject to the same  assumptions,
qualifications,  exceptions and other  limitations set forth therein.  We do not
express any opinion on any issue not expressly addressed below.

     Based upon the foregoing, it is our opinion that:

     1. The Registration Statement has become effective under the Securities Act
of 1933,  as amended (the  "Act"),  and, to the best of our  knowledge,  no stop
order suspending the effectiveness of the Registration Statement has been issued
or threatened under Section 8(d) of the Act.

     2. The Registration  Statement,  at the Effective Date, and the Prospectus,
as of the date of the Prospectus Supplement, other than financial or statistical
information  or  Computational   Materials  or  ABS  Term  Sheets  contained  or
incorporated by reference therein,  complied as to form in all material respects
with  the  requirements  of the Act and the  applicable  rules  and  regulations
thereunder.

     3. To our knowledge, there are no material contracts,  indentures, or other
documents  (not  including  Computational  Materials  and ABS Term  Sheets) of a
character  required to be described or referred to under either the Registration
Statement  or the  Prospectus  or to be filed as  exhibits  to the  Registration
Statement  other  than  those  described  or  referred  to  therein  or filed or
incorporated by reference as exhibits thereto.

     4. The  Certificates,  when duly and validly  executed,  authenticated  and
delivered in accordance with the Pooling and Servicing  Agreement,  and paid for
in and delivered in accordance with the  Underwriting  Agreement and Certificate
Purchase  Agreement,  will  be  entitled  to the  benefits  of the  Pooling  and
Servicing Agreement.

     5. The statements  contained in the  Prospectus  and the Private  Placement
Memorandum under the headings "ERISA Considerations" and "Certain Federal Income
Tax Consequences",  to the extent that they constitute matters of federal law or
legal  conclusions  with respect  thereto,  while not  purporting to discuss all
possible  consequences  of  investment in the  Certificates,  are correct in all
material  respects  with  respect  to those  consequences  or  matters  that are
discussed therein.

     6. The Pooling and  Servicing  Agreement  is not  required to be  qualified
under the Trust Indenture Act of 1939, as amended, and the Trust Fund created by
the Pooling and Servicing  Agreement is not required to be registered  under the
Investment Company Act of 1940, as amended.

                                     A-1-3

<PAGE>


     7. No consent, approval,  authorization or order of any federal or State of
New York court or governmental  agency or body is required for the  consummation
by the Company or GMACCM of the  transactions  contemplated  by the terms of the
Agreements,  except (a) such as have been obtained under the Act and (b) such as
may be required under the blue sky laws of any  jurisdiction  in connection with
the purchase and the offer and sale of the Publicly Offered  Certificates by the
Underwriters, as to which we express no opinion.

     8. Neither the issuance  and the sale of the  Certificates  pursuant to the
Agreements,  nor the consummation of any other of the transactions  contemplated
by, or the  fulfillment by the Company or GMACCM of the terms of the Agreements,
will result in a breach of any term or  provision of any federal or State of New
York statute or  regulation  or, to the best of our  knowledge,  conflict  with,
result in a breach,  violation or  acceleration of or constitute a default under
any  order  of  any  federal  or  State  of New  York  court,  regulatory  body,
administrative  agency or governmental body having jurisdiction over the Company
or GMACCM.

     9. 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  all  other  parties  thereto,  each  of the  Agreements  will
constitute  a valid,  legal and  binding  agreement  of the  Company and GMACCM,
enforceable  against the Company and GMACCM in accordance with its 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 any of the
Agreements which purport to provide  indemnification  with respect to securities
law violations.

     10. As described in the  Prospectus and the Private  Placement  Memorandum,
and assuming (i) the making of appropriate  elections and (ii)  compliance  with
all the provisions of the Agreements,  for federal income tax purposes,  each of
REMIC  I,  REMIC  II and  REMIC  III  will  qualify  as a real  estate  mortgage
investment  conduit (a "REMIC") within the meaning of Sections 860A through 860G
(the "REMIC  Provisions")  of the Internal  Revenue Code of 1986 (the "Code") in
effect on the date hereof,  and (i) the Class R-I Certificates  will be the sole
class of "residual  interests" in REMIC I, (ii) the Class R-II Certificates will
be the sole  class of  "residual  interests"  in REMIC  II,  (iii) the REMIC III
Regular  Certificates  will be "regular  interests"  in REMIC III,  and (iv) the
Class R-III Certificates will be the sole class of "residual interests" in REMIC
III.

     11.  For  purposes  of City and State of New York  income  and  corporation
franchise  tax as in effect on the date  hereof,  each of REMIC I,  REMIC II and
REMIC III will be classified as a REMIC and not a  corporation,  partnership  or
trust,  in conformity  with the federal income tax treatment of each such REMIC.
Accordingly,  each of REMIC I,  REMIC II and REMIC  III will be exempt  from all
City and State of New York taxation imposed on its income,  franchise or capital
stock,  and its assets will not be included in the  calculation of any franchise
tax liability.

     In rendering the opinions  expressed above we express no opinion  regarding
any severability  provision in the Agreements or regarding the legal,  valid and
binding effect or the

                                     A-1-4

<PAGE>

enforceability of any indemnification  provision in the Agreements to the extent
that any such  provisions  may be deemed  to cover  matters  under  the  federal
securities laws. The opinions  expressed in paragraph 9 above are subject to the
further  qualification that certain of the remedial provisions in the Agreements
may be limited or  rendered  ineffective  or  unenforceable  in whole or in part
under the laws of the State of New York (but the  inclusion  of such  provisions
does  not  make the  remedies  provided  by the  Agreements  inadequate  for the
practical  realization  of the  rights and  benefits  purported  to be  provided
thereby, except for the economic consequences of procedural or other delay).

     Whenever our opinion  with respect to the  existence or absence of facts is
indicated to be based on our  knowledge or  awareness,  we are  referring to the
actual knowledge of the Mayer,  Brown & Platt attorneys who have represented you
in connection with the  transactions  contemplated by the Agreements.  Except as
expressly set forth herein, we have not undertaken any independent investigation
to determine  the  existence or absence of such facts and no inference as to our
knowledge  concerning  such  facts  should  be drawn  from the  fact  that  such
representation has been undertaken by us.

     This  opinion  letter is rendered  for the sole  benefit of each  addressee
hereof, and no other person or entity is entitled to rely hereon. 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.

                                                Very truly yours,


                                                MAYER, BROWN & PLATT

                   GMAC Commercial Mortgage Securities, Inc., Mortgage
                   Pass-Through Certificates, Series 1999-C2
                   ---------------------------------------------------

Ladies and Gentlemen:

     We have acted as special  counsel to GMAC Commercial  Mortgage  Securities,
Inc. (the  "Company") and GMAC  Commercial  Mortgage  Corporation  ("GMACCM") in
connection   with  the   issuance  by  the  Company  of  Mortgage   Pass-Through
Certificates,   Series  1999-C2  (the   "Certificates"),   evidencing  undivided
interests  in a trust fund (the "Trust  Fund")  consisting  primarily of certain
mortgage  loans (the  "Mortgage  Loans"),  pursuant to the Pooling and Servicing
Agreement,  dated as of June 1, 1999 (the  "Pooling and  Servicing  Agreement"),
among the Company as depositor,  GMACCM as master servicer and special servicer,
LaSalle Bank National  Association as trustee (the  "Trustee") and ABN AMRO Bank
N.V., as fiscal agent (the "Fiscal Agent").

     Certain of the  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 May  25,  1999  (the  "GMACCM  Mortgage  Loan  Purchase
Agreement"),  between the Company and the Seller.  Certain of the Mortgage Loans
were purchased by the Company from Column Financial,  Inc.  ("Column")  pursuant
to,  and  for  the  consideration  described  in,  the  Mortgage  Loan  Purchase
Agreement,  dated May 25, 1999 (the "Column  Mortgage Loan Purchase  Agreement")
between the Company and Column.  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 May 25, 1999 (the "GACC  Mortgage Loan Purchase  Agreement"),  between the
Company  and  GACC.  Mortgage  Company  ("GSMC"),   pursuant  to,  and  for  the
consideration  described in, the Mortgage Loan Purchase  Agreement,  dated as of
May 25, 1999 (the "GSMC Mortgage Loan Purchase Agreement"),  between the Company
and GSMC.

     The Company has sold the Class X, Class A-1,  Class A-2,  Class B, Class C,
Class D, Class E, Class F and Class G to Donaldson, Lufkin & Jenrette Securities
Corporation,  Deutsche  Bank  Securities  Inc. and  Goldman,  Sachs & Co. as the
underwriters (the "Underwriters") named in the Underwriting Agreement, dated May
25, 1999 (the AUnderwriting Agreement"),  among the Company, the Seller, and the
Underwriters.  The Company  sold the Class H, Class J, Class K, Class L, Class M
and Class N  Certificates  to  Commercial  Asset  Trading  Inc.  pursuant to the
Certificate  Purchase Agreement,  dated May 25, 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  Credit  Suisse  First  Boston
Corporation. The Certificate

                                     A-2-1

<PAGE>

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

     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 has filed 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 May 25, 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."

     Because  of  the  wholly  or   partially   non-legal   character   of  many
determinations  involved in the preparation of the Registration  Statement,  the
Prospectus and the Private Placement Memorandum, we are not advising herein with
respect  to and do not  assume  any  responsibility  herein  for  the  accuracy,
completeness  or  fairness  of the  statements  contained  in  the  Registration
Statement,  the  Prospectus  or the  Private  Placement  Memorandum  and make no
representation  herein  that  we  have  otherwise   independently  verified  the
accuracy, completeness or fairness of such statements. In particular and without
limiting  the  foregoing,  we  express  no  advice  as to any  such  accounting,
financial or statistical  information  contained in the Registration  Statement,
the Prospectus or the Private Placement  Memorandum,  or as to any Computational
Materials or ABS Term Sheets, and we have not examined any accounting, financial
or  statistical  records  from which the  information  and  statements  included
therein were derived. In addition,  with limited exception, we have not reviewed
any of the Mortgage Notes, Mortgages or other documents in the Mortgage Files or
made any inquiry of any originator of any Mortgage Loan other than GMACCM.

     We do  not  act as  general  counsel  to  the  Company  or  GMACCM.  In our
representation  of the Company and GMACCM in  connection  with the  transactions
contemplated by the Agreements,  however, we met in conferences and participated
in telephone  conversations  with  representatives of parties to the Agreements,
Donaldson,  Lufkin & Jenrette Securities  Corporation,  Deutsche Bank Securities
Inc. and Goldman,  Sachs & Co. and their  respective  counsel in addition to us.
During  those  conferences  and  telephone  conversations,  the  contents of the
Registration Statement,  the Prospectus and the Private Placement Memorandum and
related matters were discussed.  With respect to the accuracy,  completeness and
fairness of the

                                     A-2-2

<PAGE>

information relating to GMACCM and the Trustee and the Fiscal Agent contained in
the  Prospectus  and  the  Private  Placement   Memorandum  under  the  captions
"Description  of the  Mortgage  Pool--The  Seller,"  "Servicing  of the Mortgage
Loans--The  Servicer"  and  "Description  of the  Certificates--The  Trustee and
Fiscal Agent",  we have relied  exclusively on those  conferences  and telephone
conversations  and that no  information  inconsistent  therewith has come to our
attention.  In addition,  we have examined the Agreements  and reviewed  various
opinions rendered and certificates  delivered in connection with the issuance of
the  Certificates.  We have not otherwise  undertaken any  procedures  that were
intended or likely to elicit information  concerning the accuracy,  completeness
or fairness of the statements made in the Registration Statement, the Prospectus
or the Private Placement Memorandum.  We have assumed that there is not and will
not be any other agreement that materially supplements or otherwise modifies the
agreements expressed in the Agreements.

     Based  upon and  subject  to the  foregoing,  and  further  based  upon our
understanding  of  applicable  law and the  experience  we  have  gained  in our
practice  thereunder,  we hereby advise you that no information  has come to our
attention  that causes us to believe that (i) the  Registration  Statement as of
the date it became  effective,  contained or contains any untrue  statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the  statements  therein  not  misleading  and (ii) the  Prospectus  or the
Private  Placement  Memorandum  as of the date  thereof or hereof,  contained or
contains any untrue  statement of a material fact or omitted or omits 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.

     Whenever our opinion  with respect to the  existence or absence of facts is
indicated to be based on our  knowledge or  awareness,  we are  referring to the
actual knowledge of the Mayer,  Brown & Platt attorneys who have represented the
Company  and GMACCM in  connection  with the  transactions  contemplated  by the
Agreements.  Except as expressly set forth herein,  we have not  undertaken  any
independent  investigation  to determine  the existence or absence or such facts
and no inference as to our knowledge  concerning such facts should be drawn from
the fact that such representation has been undertaken by us.

     This letter is provided for the sole benefit of each addressee hereof,  and
no other person or entity is entitled to rely hereon.  Copies of this letter may
not be  furnished  to any other  person or entity,  nor may any  portion of this
letter be quoted, circulated or referred to in any other document.


                                                 Very truly yours,

                                                                    June 9, 1999

To:  Persons Listed on Annex A hereto

GMAC Commercial Mortgage Securities, Inc.,
Mortgage Pass-Through Certificates, Series 1999-C2

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-C2  (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 June 1, 1999 (the  "Pooling and  Servicing  Agreement"),
among the Company as depositor,  GMACCM as master servicer and special  servicer
and LaSalle Bank National  Association,  as trustee (the "Trustee") and ABN AMRO
Bank N.V., as fiscal agent.

     Certain of the Mortgage Loans (the "GACC Mortgage Loans") were purchased by
the Company from German  American  Capital  Corporation  ("GACC")  pursuant to a
mortgage loan purchase  agreement,  dated as of May 25, 1999 (the "GACC Mortgage
Loan Purchase Agreement"), between the Company and GACC. Certain of the Mortgage
Loans (the "Column  Mortgage  Loans") were  purchased by the Company from Column
Financial, Inc. ("Column") pursuant to a mortgage loan purchase agreement, dated
as of May 25, 1999 (the "Column Mortgage Loan Purchase Agreement"),  between the
Company and Column.  Certain of the Mortgage Loans (the "GSMC  Mortgage  Loans")
were  purchased by the Company  from Goldman  Sachs  Mortgage  Company  ("GSMC")
pursuant to a mortgage  loan purchase  agreement,  dated May 25, 1999 (the "GSMC
Mortgage Loan Purchase Agreement"), between the Company and GSMC. Certain of the
Mortgage Loans (the "GMACCM  Mortgage Loans") were purchased by the Company from
GMACCM pursuant to a mortgage loan purchase  agreement,  dated May 25, 1999 (the
"GMACCM Mortgage Loan Purchase Agreement"),  between the Company and GMACCM (the
GMACCM  Mortgage  Loans,  together  with the GACC  Mortgage  Loans,  the  Column
Mortgage Loans and the GSMC Loans, the "Mortgage Loans").

     The Company sold the Class X, Class A-1, Class A-2, Class B, Class C, Class
D, Class E, Class F and Class G  Certificates  to  Donaldson,  Lufkin & Jenrette
Securities  Corporation  ("DLJ"),   Goldman,  Sachs  &  Co.  and  Deutsche  Bank
Securities  Inc.  as  the  underwriters  (the   "Underwriters")   named  in  the
Underwriting Agreement, dated May 25, 1999 (the "Underwriting Agreement"), among
the Company,  GMACCM and the Underwriters.  The Company sold all of the Class H,
Class J, Class K, Class L, Class M and Class N Certificates to Commercial  Asset
Trading  Inc.  ("CATI")  as initial  purchaser  (in such  capacity,  an "Initial

                                      B-1

<PAGE>

Purchaser") pursuant to the Certificate Purchase Agreement,  dated as of May 25,
1999 (the "Certificate Purchase  Agreement"),  between the Company and CATI. The
Company sold the Class R-I,  Class R-II and Class R-III  Certificates  to Credit
Suisse First Boston  Corporation  as initial  purchaser  (in such  capacity,  an
"Initial  Purchaser").  The Certificate  Purchase  Agreement,  the  Underwriting
Agreement,  the GACC Purchase Agreement, the Column Purchase Agreement, the GSMC
Purchase Agreement,  the GMACCM 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, (ii) general principles of equity,


                                       B-2
<PAGE>

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 Mayer, Brown & Platt, 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,

     Pursuant to Section 4.3 of the Underwriting  Agreement,  dated May 25, 1999
(the "Underwriting Agreement"), among GMAC Commercial Mortgage Securities, Inc.,
GMAC Commercial Mortgage  Corporation,  Donaldson,  Lufkin & Jenrette Securities
Corporation,  Goldman Sachs & Co. and Deutsche  Bank  Securities  Inc.,  each an
underwriter set forth therein (collectively the "Underwriters")  relating to the
Certificates referenced above, each of the undersigned does hereby certify that:

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

     (b) With respect to each class of Certificates, set forth below is (i), the
first price at which 10% of the  aggregate  actual or notional,  as the case may
be, principal  balance of each such class of Certificates was sold to the public
at a  single  price,  if  applicable,  or (ii) if more  than  10% of a class  of
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
the public,  the purchase price for each such class of Certificates  paid by the
Underwriters  expressed as a percentage  of the actual or notional,  as the case
may be,  principal  balance of such  class of  Certificates  calculated  by: (1)
estimating  the fair market value of each such class of  Certificates  as of May
__, 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 class of Certificates:

<PAGE>



     This  Pooling and  Servicing  Agreement  (this  "Agreement"),  is dated and
effective as of June 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 LASALLE BANK NATIONAL
ASSOCIATION, as Trustee and ABN AMRO BANK N.V., as Fiscal Agent.


                             PRELIMINARY STATEMENT:

     The Depositor intends to sell the  Certificates,  to be issued hereunder in
multiple  Classes,  which in the aggregate  will evidence the entire  beneficial
ownership interest in the Trust Fund to be created hereunder, the primary assets
of which will be the Mortgage  Loans.  The aggregate of the initial Cut-off Date
Principal Balances of the Mortgage Loans is approximately $974,502,236.

     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.

     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
Date, the longest remaining amortization schedule, irrespective of its scheduled
maturity.

acknowledged and delivered,  as amended,  modified,  renewed or extended through
the date hereof and from time to time hereafter.

     "Assumed  Monthly  Payment":  With respect to any Balloon Mortgage Loan for
its Stated  Maturity Date (provided that such Mortgage Loan has not been paid in
full,  and no other  Liquidation  Event has occurred in respect  thereof,  on or
before the end of the  Collection  Period in which  such  Stated  Maturity  Date
occurs (or in the case of a Late Due Date Mortgage Loan, on or before the end of
the Collection Period immediately  preceding the Collection Period in which such
Stated  Maturity  Date occurs)) and for any  subsequent  Due Date therefor as of
which such Mortgage Loan remains  outstanding and part of the Trust Fund (or, in
the case of a Late Due Date Mortgage  Loan, for any subsequent Due Date therefor
which follows in the same month a  Determination  Date as of which such Mortgage
Loan  remains  outstanding  and part of the Trust Fund),  if no Monthly  Payment
(other than the related Balloon Payment) is due for such Due Date, the scheduled
monthly payment of principal and/or interest deemed to be due in respect thereof
for the  Stated  Maturity  Date

amortization  schedule  (if any),  in effect  immediately  prior to, and without
regard to the  occurrence  of, its most recent  scheduled  maturity  date.  With
respect to any REO Loan,  for any Due Date therefor as of which (or, in the case
of a Late Due Date Mortgage Loan, for any Due Date therefor which follows in the
same month a  Determination  Date as of which) the related REO Property  remains
part of the Trust  Fund,  the  scheduled  monthly  payment of  principal  and/or
interest  deemed  to be due in  respect  thereof  on such Due Date  equal to the
Monthly  Payment (or, in the case of a Balloon  Mortgage  Loan  described in the
preceding sentence of this definition, the Assumed Monthly Payment) exclusive of
any  Excess  Interest  that was due (or deemed  due) in  respect of the  related
Mortgage Loan for the last Due Date prior to its becoming an REO Loan.

amount of any  Delinquency  Advances made by the Master  Servicer or Trustee for

                          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

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 the  Custodian  (with a copy to the Master
Servicer),  on or before the Closing  Date,  the Mortgage  File for each of such
Mortgage Loan Seller's Mortgage Loans 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  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


                                       59

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  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

     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 Defect or Breach
would cause the  Mortgage  Loan to be other than a  "qualified  mortgage"  under
Section  860G(a)(3)  of the Code,  such  Defect or Breach  shall be cured or the
related  Mortgage  Loan  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 or event  under the


                                       63
<PAGE>

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.



                                       64

     (d) The Trustee shall, for the benefit of the  Certificateholders,  enforce
the  obligations  of each  Mortgage  Loan Seller under  Section 6 of the related
Mortgage Loan Purchase  Agreement and the  obligations of GMACCM under Section 4
of each Supplemental Agreement. Such enforcement, including, without limitation,
the legal  prosecution  of claims,  shall be carried  out in such form,  to such
extent and at such time as the Trustee would require were it, in its  individual
capacity,  the owner of the  affected  Mortgage  Loan(s).  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.

                                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 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

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

instruments, with respect to


                                       67
<PAGE>

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 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 Fiscal Agent, 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.

     (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


                                       69
<PAGE>

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 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,

     (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 Excess  Liquidation  Proceeds and
Liquidation  Proceeds that are received in connection with the Master Servicer's
or the Depositor's  purchase of all the Mortgage Loans 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  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.



                                       71

     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:

     (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



                                       72

     (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. (312) 499-5406 (or such  alternative  number provided by the Master
Servicer to the Trustee in writing)  and by  telephone  at  telephone  no. (312)
499-5485  (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. To the extent the Master Servicer has not delivered
to the Trustee  for  deposit in the  Distribution  Account  such  amounts as are
required to be  delivered on the Master  Servicer  Remittance  Date,  the Master
Servicer shall pay interest  thereon to the Trustee at an interest rate equal to
the  Reimbursement  Rate then in effect for the period from the Master Servicing
Remittance Date to and excluding the date such amounts are deposited.

     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  Loss, 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 Loss, 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  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


                                       73
<PAGE>

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.

     (d) The  Trustee  shall  establish  and  maintain  the  Excess  Liquidation

Excess Liquidation  Proceeds 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 Excess  Liquidation  Reserve  Proceeds Account may be
invested  by the  Trustee  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.

     Upon  the  disposition  of any REO  Property  in  accordance  with  Section
3.18(d), the Special Servicer will calculate the Excess Liquidation Proceeds, if
any, realized in connection with such sale and deposit such amount in the Excess
Liquidation Proceeds Reserve Account.

of amounts  relating to the Trust Fund held in the Interest Reserve Account (but
only to the extent of Net  Investment  Earnings  with  respect  to the  Interest
Reserve Account for any Collection Period).

     (d) The Trustee shall, on any Distribution  Date, make withdrawals from the
Excess  Liquidation  Proceeds Reserve Account to the extent required to make the
distributions from the Excess  Liquidation  Proceeds Reserve Account required by
Section 4.01(c).

     SECTION  3.06  Investment  of  Funds  in  the  Certificate   Account,   the
                    Distribution   Account,   the  Excess  Liquidation  Proceeds
                    Reserve  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,  the  Excess  Liquidation
Proceeds Reserve Account or the Interest Reserve Account to invest,  or if it 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,  the Excess  Liquidation  Proceeds  Reserve  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


                                       78
<PAGE>

demand,  the  Master  Servicer  (in the  case of the  Certificate  Account,  any
Lock-Box Account,  the Excess Liquidation  Proceeds Reserve 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,  the Excess  Liquidation  Proceeds
Reserve Account or any Cash Collateral  Account,  interest and investment income
realized on funds  deposited in each such Investment  Account,  to the extent of
the Net  Investment  Earnings,  if any,  with  respect to such  account for each
Collection  Period,  shall be for the sole and  exclusive  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, the Excess Liquidation Proceeds Reserve Account or the Interest Reserve
Account,  the  Trustee  shall  immediately  deposit  therein,  without  right of
reimbursement,  the amount of the Net  Investment  Loss, if any, with respect to
such  account.  If any loss  shall  be  incurred  in  respect  of any  Permitted
Investment on deposit in the REO Account,  the Special  Servicer  shall promptly
deposit  therein from its own funds,  without right of  reimbursement,  no later
than the end of the Collection  Period during which such loss was incurred,  the
amount of the Net Investment Loss, if any, for such Collection Period

                                       79
<PAGE>

     (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 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  guideline  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


                                       80
<PAGE>

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 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


                                       81
<PAGE>

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).

     (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 (w) two  increments  (but not less than BBB)  below the  rating of the
highest  rated  Certificate  from Standard & Poor's (x) A2 by Moody'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  (w),  (x) and (y) shall not be  applicable  with  respect  to  Moody's,
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  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 and  Moody'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


                                       83
<PAGE>

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)(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 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), (B) Standard & Poor's (in
all  cases),  and (C)  Moody'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
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,  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) The Master  Servicer  shall have  obtained an Opinion of Counsel from
the  related  Mortgagor  to the effect that such  release  will not cause any of
REMIC I,  REMIC II or REMIC III to fail to  qualify  as a REMIC at any time that
any  Certificates are outstanding or cause a tax to be imposed on the Trust Fund
under the REMIC Provisions;

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



                                       85
<PAGE>

     (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 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


                                       86
<PAGE>

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



                                       87
<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.



                                       88
<PAGE>

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


                                       89
<PAGE>

or rights  provided by the Mortgage  Note or Mortgage or otherwise  available at
law or in equity.  The Special Servicer shall be responsible for the preparation
of  all  such  documents  and  pleadings.  When  submitted  to the  Trustee  for
signature,  such documents or pleadings shall be accompanied by a certificate of
a Servicing  Officer  requesting that such pleadings or documents be executed by
the Trustee and  certifying  as to the reason such  documents or  pleadings  are
required and that the  execution  and  delivery  thereof by the Trustee will not
invalidate  or  otherwise  affect  the  lien  of the  Mortgage,  except  for the
termination of such a lien upon completion of the foreclosure or trustee's sale.

     SECTION 3.11 Servicing Compensation; Nonrecoverable Servicing Advances.

     (a) As compensation for its activities hereunder, the Master Servicer shall
be entitled to receive the  Servicing Fee with respect to each Mortgage Loan and
REO Loan. 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


                                       90
<PAGE>

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.

     (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


                                       91
<PAGE>

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.

     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.  If the Trustee  fails to make a Servicing
Advance  required  to be made by it, the Fiscal  Agent  shall make such  advance
(subject to Section  3.11(g)


                                       92
<PAGE>

below) within one (1) Business Day of such failure by the Trustee. The making of
such  Advance by the Fiscal  Agent shall cure the failure by the Trustee to make
such Advance.

     (f) The Master Servicer,  the Special Servicer,  the Trustee and the Fiscal
Agent shall each be entitled to receive  interest at the  Reimbursement  Rate in
effect from time to time,  accrued on the amount of each Servicing  Advance made
thereby for so long as such Servicing  Advance is outstanding,  payable,  first,
out of Penalty  Charges  received on the  Mortgage  Loan or 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, the Trustee or the Fiscal Agent shall be
required to make any Servicing  Advance that it  determines  in its  reasonable,
good  faith  judgment  would  constitute  a  Nonrecoverable  Servicing  Advance;
provided,  however,  that the Special  Servicer  may make an  Emergency  Advance
notwithstanding that, at the time such Advance is made, the Special Servicer may
not have adequate information available in order to make a determination whether
or not such advance would, if made, be a Nonrecoverable  Servicing  Advance.  In
addition,  Nonrecoverable  Servicing Advances  (including any Emergency Advances
made  pursuant to the proviso of the  preceding  sentence  which are  ultimately
determined  to be  Nonrecoverable  Servicing  Advances)  shall  be  reimbursable
pursuant to Section 3.05 out of general  collections  on the Mortgage  Loans and
REO Properties on deposit in the Certificate  Account.  The determination by the
Master  Servicer,  the Special  Servicer or, if  applicable,  the Trustee or the
Fiscal Agent,  that it has made a Nonrecoverable  Servicing  Advance or that any
proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing
Advance,  shall be evidenced by an Officer's  Certificate  delivered promptly to
the Trustee (or, if applicable,  retained  thereby) and the  Depositor,  setting
forth the basis for such determination,  together with (if such determination is
prior to the liquidation of the related Mortgage Loan or 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,  the Trustee or the Fiscal Agent, as the case may be, may,  subject to
its reasonable and good faith determination that such Appraisal will demonstrate
the  nonrecoverability  of the related  Advance,  obtain an  Appraisal  for such
purpose at the expense of the Trust Fund.  The Trustee or the Fiscal Agent shall
be entitled to rely on any determination of nonrecoverability that may have been
made by the Master Servicer or the Special Servicer with respect to a particular
Servicing  Advance,  and the Master  Servicer  shall be  entitled to rely on any
determination  of  nonrecoverability  that may  have  been  made by the  Special
Servicer with respect to a particular Servicing Advance.

     SECTION 3.12 Inspections; Collection of Financial Statements.

     (a) The Master Servicer shall perform (or cause to be performed) a physical
inspection  of  each  Mortgaged   Property  (other  than  Mortgaged   Properties
constituting  collateral for Specially  Serviced  Mortgaged Loans) at such times
and in such manner as are  consistent  with the Servicing  Standard,  but in any
event at least  once  every two years or,  if the  related  Mortgage  Loan 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 if the related
Tenant  or its  Guarantor  has a  published  rating of not less than BBB- or its
equivalent from any nationally-recognized rating agency, every two years, if the
related  Tenant or its guarantor has a published  rating  between BB+ and BB- or
its equivalent from any nationally-recognized rating agency, and annually if the
related  Tenant or its Guarantor has a published  rating of less than BB- or its
equivalent from any  nationally-recognized  rating agency.  Notwithstanding  the
foregoing, the Master Servicer shall perform (or cause to be performed) annually
a physical  inspection of each Mortgaged  Property for which no published rating
is publicly  available for the related  Tenant under each Credit Lease Loan that
represents 5% or more of the initial principal balance of the Mortgage Pool, and
will  inspect or cause to be inspected  every  second year each other  Mortgaged
Property for which the related Tenant or its Guarantor has no published publicly
available rating.).  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,  Moody'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 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


                                       94
<PAGE>

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.

     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


                                       95
<PAGE>

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
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


                                       96
<PAGE>

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 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.



                                       97
<PAGE>

     (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 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.



                                       98
<PAGE>

     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.

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


                                       99
<PAGE>

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 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


                                      100
<PAGE>

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 at the
expense of the purchasing party such  instruments of transfer or assignment,  in
each case without recourse, representation or warranty, as shall be necessary to
vest in the  Master  Servicer  or the  Special  Servicer,  as  applicable,  such
Defaulted  Mortgage  Loan.  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


                                      101
<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  Liquidation  Proceeds (net of
related Liquidation  Expenses) for any REO Property purchased hereunder shall be
deposited  in the  Certificate  Account,  except  that any  portion of  proceeds
consisting  of Excess  Liquidation  Proceeds  shall be  deposited  in the Excess
Liquidation Proceeds Reserve Account.

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

     (e)  Whether  any cash  bid  constitutes  a fair  price  for any  Defaulted
Mortgage  Loan or REO  Property,  as the case may be,  for  purposes  of Section
3.18(d), shall be determined by the Special Servicer, if the highest bidder is a
Person  other than an  Interested  Person,  and by the  Trustee,  if the highest
bidder  is an  Interested  Person;  provided,  however,  that  no  bid  from  an
Interested Person shall constitute a fair price unless (i) it is the highest bid
received and (ii) at least two other bids are received  from  independent  third
parties.  In determining  whether any offer  received from an Interested  Person
represents a fair price for any such Mortgage Loan 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.



                                      102
<PAGE>

     (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
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,


                                      103
<PAGE>

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 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.



                                      104
<PAGE>

     (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  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


                                      105
<PAGE>

foregoing  shall not limit the Servicer  and Special  Servicer's  obligation  to
establish  or direct the  related  Mortgagor  to  establish  a Lock-Box  Account
pursuant to Section 3.24.

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

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

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

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

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

     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


                                      106
<PAGE>

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 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

                                      107
<PAGE>

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
analysis and  determination  that the modification,  waiver,  amendment or other
action contemplated by Section 3.20(a) is reasonably likely to produce a greater
recovery to  Certificateholders on a present value basis than would liquidation,
should prove to be wrong or incorrect, so long as the analysis and determination
were made on a reasonable  basis in good faith by the Master Servicer or Special
Servicer  and the Master  Servicer  or Special  Servicer  was not  negligent  in
ascertaining the pertinent facts.

     (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


                                      108
<PAGE>

consent,  modification,  waiver or indulgence or any other matter or thing,  the
granting  of which is within the Master  Servicer's  or the  Special  Servicer's
discretion  pursuant to the terms of the instruments  evidencing or securing the
related  Mortgage Loan and is permitted by the terms of this Agreement,  require
that  such  Mortgagor  pay  to  it,  as  additional  servicing  compensation,  a
reasonable or customary fee (not to exceed 1.0% of the unpaid principal  balance
of  the  related  Mortgage  Loan)  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
copies thereof) and records (including records stored electronically on computer
tapes, magnetic discs and the like) relating to the Mortgage Loan and reasonably
requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto without acting through a Sub-Servicer.  The Master Servicer
shall use reasonable  efforts to comply with the preceding  sentence within five
Business Days of the occurrence of each related  Servicing  Transfer Event.  The
Special  Servicer  may,  as to  any  delinquent  Mortgage  Loan,  prior  to  the
occurrence  of a Servicing  Transfer  Event with  respect  thereto,  request and
obtain the foregoing documents and information.

     Upon  determining  that a  Specially  Serviced  Mortgage  Loan has become a
Corrected  Mortgage  Loan and if the  Master  Servicer  is not also the  Special
Servicer,  the Special  Servicer shall promptly give notice thereof,  and return
the related  Servicing File, to the Master Servicer and upon giving such notice,
and  returning  such  Servicing  File,  to  the  Master  Servicer,  the  Special
Servicer's  obligation to service such Mortgage Loan, and the Special Servicer's
right to receive the Special  Servicing Fee with respect to such Mortgage  Loan,

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

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

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

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

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

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

     (a) The Majority  Certificateholder  of the Controlling  Class,  may at any
time and from time to time replace any existing  Special Servicer or any Special
Servicer  that has  resigned or otherwise  ceased to serve as Special  Servicer,
including  pursuant to Section 7.01. Such Holders shall so designate a Person to
so serve by the  delivery  to the  Trustee  of a  written  notice  stating  such
designation,  subject to 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

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

liability to the Trust or the  Certificateholders  for any action taken,  or for
refraining  from the  taking  of any  action,  in good  faith  pursuant  to this
Agreement,  or for  errors  in  judgment.  Each  Holder  and  Certificate  Owner
acknowledges  and agrees,  by its acceptance of its  Certificates or an interest
therein,  that the Majority  Certificateholder of the Controlling Class may have
special  relationships  and  interests  that  conflict with those of Holders and
Certificate  Owners of one or more  Classes of  Certificates,  that the Majority
Certificateholder  of the  Controlling  Class may act solely in the interests of
the Holders and Certificate  Owners of the Controlling  Class, that the Majority
Certificateholder  of the  Controlling  Class  does not have any  duties  to the
Holders  and  Certificate  Owners of any Class of  Certificates  other  than the
Controlling Class, that the Majority  Certificateholder of the Controlling Class
may take actions that favor interests of the Holders and  Certificate  Owners of
the Controlling  Class over the interests of the Holders and Certificate  Owners
of  one  or  more  other  Classes  of   Certificates,   and  that  the  Majority

                                      112
<PAGE>

Certificateholder  of the Controlling  Class shall have no liability  whatsoever
for having so acted,  and no  Certificateholder  may take any action  whatsoever
against the Majority Certificateholder of the Controlling Class or any director,
officer, employee, agent or principal thereof for having so acted.

     SECTION 3.24 Lock-Box Accounts and Servicing Accounts.

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

     (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.

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.

material adverse effect on the performance by GMACCM under this Agreement.

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

(xxiii),  (xxvi), (xxix), (xxxii), and (xxxv) above with respect to any Class of

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

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:



                                      121
<PAGE>

     (i) to the  Holders  of the Class A,  Class B,  Class C,  Class D, Class E,
Class F and Class G  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 N Certificates,  without
regard to whether  any such Class is entitled  to  distributions  of interest or
principal on such  Distribution  Date (whether by reason of its Class  Principal
Balance  having been reduced to zero, by reason of it not yet being  entitled to
distributions of principal, or for any other reason).

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

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

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

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

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

                                      122
<PAGE>

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

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

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

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

     (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



                                      123
<PAGE>

     (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.

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

applicable  law and (F) the  Trustee  shall be entitled  to  distribute  or make

extent the  Trustee  deems the same to be  necessary  or  appropriate).  Nothing
herein shall be construed to impose upon the Trustee any  obligation  or duty to
furnish or distribute any Additional  Information to any Person in any instance,
and the  Trustee  shall  neither  have  any  liability  for  furnishing  nor for
refraining from furnishing Additional  Information in any instance.  The Trustee
shall be entitled (but not required) to request and receive  direction  from the
Depositor as to the manner of delivery of any such  Additional  Information,  if

Upon  request,  the Trustee shall deliver or shall cause to be delivered to each

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

     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 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.(312) 499-5406 (or
such  alternative  number  provided  by the Master  Servicer  to the  Trustee in
writing) and by telephone at telephone  no. (312) 499- 5485  (Attention:  Master
Servicing  Manager) (or such alternative  number provided by the Master Servicer
to the  Trustee in writing) as soon as  possible,  but in any event  before 5:00
p.m., New York City time, on such day. If after such notice the Trustee does not
receive the full  amount of such  Delinquency  Advances by 11:00 a.m.,  New York
City time,  on the  Business  Day  immediately  following  such Master  Servicer
Remittance  Date,  then the Trustee  shall make the portion of such  Delinquency
Advances  that was  required  to be, but was not,  made by the  Master  Servicer
pursuant to this Section  4.03(a).  If the Trustee  fails to make a  Delinquency
Advance  required to be made by it  hereunder,  the Fiscal Agent shall make such
advance  no  later  than  1:00  p.m.  New York  City  time on the  Business  Day
immediately  following such Master Servicer  Remittance Date. The making of such
Advance by the Fiscal  Agent  shall cure the failure by the Trustee to make such
Advance.

     (b) The aggregate  amount of Delinquency  Advances to be made by the Master
Servicer  in respect  of the  Mortgage  Loans  (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


                                      133
<PAGE>

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

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

                                      134
<PAGE>

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, LK, LL, LM and LN 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 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 N, Class M, Class L, Class K, Class J,
Class H, Class G,  Class F,  Class E, Class D, Class C and Class B  Certificates
shall be reduced  sequentially,  in that order, in each case, until the first to
occur of such  excess  being  reduced  to zero or the  related  Class  Principal
Balance being reduced to zero.  If, after the foregoing  reductions,  the amount
described  in clause (i) of the second  preceding  sentence  still  exceeds  the
amount  described  in clause  (ii) of the second  preceding  sentence,  then the
respective Class Principal  Balances of the Class A-1 and Class A-2 Certificates
shall be reduced,  pro rata in  accordance  with the relative  sizes of the then
outstanding Class Principal Balances of such Classes of Certificates,  until the
first to occur of such excess being reduced to zero or each such Class Principal
Balance being reduced to zero. Such  reductions in the


                                      135
<PAGE>

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 N  Certificates,
with the inclusion or exclusion of appropriate bracketed provisions contained in
Exhibit A-15 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, Class K, Class L, Class M and Class N  Certificates,  and $1,000,000 in
the case of the Class X Certificates,  and in each such case in any whole dollar
denomination in excess thereof; provided,  however, that a single Certificate of
each Class  thereof  may be issued in a  different  denomination.  The  Residual
Certificates  will be issuable  only in  denominations  representing  Percentage
Interests of not less than 20% in the related Class.

     (b) The Certificates shall be executed by manual or facsimile  signature on
behalf of the Trustee in its  capacity  as trustee  hereunder  by an  authorized
officer.  Certificates bearing the manual or facsimile signatures of individuals
who were at any time the authorized officers of the Trustee shall be entitled to
all  benefits  under  this  Agreement,   subject  to  the  following   sentence,
notwithstanding  that such  individuals  or any of them have ceased to hold such
offices prior to the authentication and delivery of such Certificates or did not
hold such  offices at the date of such  Certificates.  No  Certificate  shall be
entitled  to any  benefit  under this  Agreement,  or be valid for any  purpose,
however,   unless  there  appears  on  such   Certificate   a   certificate   of
authentication  substantially  in the form  provided for herein  executed by the
Certificate   Registrar   by  manual   signature,   and  such   certificate   of
authentication upon any Certificate shall be conclusive  evidence,  and the only
evidence,  that such  Certificate  has been  duly  authenticated  and  delivered
hereunder. All Certificates shall be dated the date of their authentication.

     SECTION 5.02 Registration of Transfer and Exchange of Certificates.

     (a) At all  times  during  the  term  of this  Agreement,  there  shall  be
maintained at the office of the Certificate  Registrar a Certificate Register in
which, subject to such reasonable  regulations as the Certificate  Registrar may
prescribe,  the  Certificate  Registrar  shall provide for the  registration  of
Certificates  and of transfers and exchanges of Certificates as herein provided.
The  Trustee  is  hereby  initially  appointed  (and  hereby  agrees  to  act in
accordance  with the terms hereof)


                                      136
<PAGE>

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 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,  the Fiscal  Agent or the
     Certificate Registrar in their respective capacities as such).

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



                                      137

     (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 FAN 97-03-E (December 9, 1996)
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,  the Fiscal Agent and the Master  Servicer with an
opinion of counsel satisfactory to the Depositor,  the Trustee, the Fiscal Agent
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,  the Fiscal Agent 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, the Fiscal Agent 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.  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  assets" of, any Plan or (b) the
purchase of any such  Certificate  by or on behalf of, or with "plan assets" of,
any Plan is permissible  under applicable law, will not result in any non-exempt
prohibited  transaction  under ERISA or Section  4975 of the Code,  and will not
subject the Depositor,  the Trustee,  the Fiscal Agent or the Master Servicer to
any  obligation  in  addition  to those  undertaken  herein,  and the  following
conditions are met: (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.  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


                                      138
<PAGE>

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
     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.



                                      139
<PAGE>

          (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 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,


                                      140
<PAGE>

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 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.



                                      141
<PAGE>

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

     (j) Upon  request,  the  Certificate  Registrar  shall  provide  the Master
Servicer,  the Special  Servicer and the  Depositor  with an updated copy of the
Certificate  Register on or about January 1 and July 1 of each year,  commencing
January 1, 2000.

     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 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

<PAGE>

     to  the  Certificate  Registrar  of  the  Book-Entry  Certificates  by  the
Depository,  accompanied by  registration  instructions  from the Depository for
registration  of  transfer  and any other  documents  necessary  to satisfy  the
requirements of any applicable transfer restrictions, the Trustee shall execute,
and the Certificate  Registrar shall  authenticate  and deliver,  the applicable
Definitive   Certificates   to  the  Certificate   Owners   identified  in  such
instructions.  None of the Depositor, the Master Servicer, the Special Servicer,
the Trustee,  the Fiscal Agent or the Certificate  Registrar shall be liable for
any delay in delivery of such  instructions,  and each may conclusively rely on,
and shall be  protected in relying on, such  instructions.  Upon the issuance of
Definitive  Certificates for purposes of evidencing  ownership of the Registered
Certificates held in book-entry form, the registered  holders of such Definitive
Certificates   shall  be  recognized  as   Certificateholders   hereunder   and,
accordingly,  shall be  entitled  directly to receive  payments  on, to exercise
Voting  Rights with  respect to, and to transfer and  exchange  such  Definitive
Certificates.

     SECTION 5.04 Mutilated, Destroyed, Lost or Stolen Certificates.

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

     SECTION 5.05 Persons Deemed Owners.

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

           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,



                                      144
<PAGE>

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.

     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


                                      145
<PAGE>

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

                                     DEFAULT

     (ii) any failure by the Special  Servicer to deposit  into,  or to remit to

continues  unremedied  for one  Business  Day  following  the date on which such
deposit or remittance was first required to be made; or

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

     (iv) any failure on the part of the Master Servicer or the Special Servicer

shall have been given to the Master  Servicer  or the Special  Servicer,  as the
case may be, by the Trustee or the Depositor,  or to the Master  Servicer or the
Special Servicer,  as the case may be by the Holders of Certificates entitled to
not less than 25% of the Voting Rights; provided, however, that if such covenant
or  agreement  is capable  of being  cured and the  Master  Servicer  or Special
Servicer,  as applicable,  is diligently  pursuing such cure, such 30 day period
shall be extended for an additional 30 days; or

     (v) any breach on the part of the Master  Servicer or the 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
continues  unremedied  for a period of 30 days after the date on which notice of
such breach,  requiring  the same to be  remedied,  shall have been given to the
Master Servicer or the Special  Servicer by the Trustee or the Depositor,  or to
the Master Servicer or the Special  Servicer,  as the case may be by the Holders
of  Certificates  entitled to not less than 25% of the Voting Rights;  provided,
however,  if such  breach is capable of being  cured and the Master  Servicer or
Special  Servicer,  as  applicable,  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
federal or state bankruptcy,  insolvency or similar law for the appointment of a
conservator,   receiver,   liquidator,   trustee  or  similar  official  in  any
bankruptcy,  insolvency,   readjustment  of  debt,  marshalling  of  assets  and
liabilities or similar proceedings,  or for the winding-up or liquidation of its
affairs,  shall have been  entered  against  the Master  Servicer or the Special
Servicer and such decree or order shall have remained in force  undischarged  or

                                      147
<PAGE>

     (vii) the Master  Servicer or the  Special  Servicer  shall  consent to the

of the foregoing; or

     (ix) the  Trustee  shall have  received  written  notice from FITCH IBCA or
Moody's that the  continuation of the Master Servicer or the Special Servicer in
such capacity would result in the downgrade,  qualification or withdrawal of any
rating then assigned by such 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 cooperate with the Trustee or any other Successor
Master  Servicer or Special


                                      148
<PAGE>

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


                                      149
<PAGE>

of the Master Servicer or the Special  Servicer,  as the case may be, hereunder.
Pending  appointment  of a  successor  to the  Master  Servicer  or the  Special
Servicer, as the case may be, hereunder,  the Trustee shall act in such capacity
as hereinabove  provided. In connection with any such appointment and assumption
described herein, the Trustee may make such arrangements for the compensation of
such  successor  out of payments on Mortgage  Loans 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.

     SECTION 8.01 Duties of Trustee and Fiscal Agent.

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

     (b) The Trustee, upon receipt of all resolutions, certificates, statements,
opinions,  reports,  documents,  orders or other  instruments  furnished  to the
Trustee  which  are  specifically  required  to be  furnished  pursuant  to  any
provision of this Agreement  (other than the Mortgage Files, the review of which
is  specifically  governed by the terms of Article  II),  shall  examine them to
determine  whether they conform to the  requirements of this  Agreement.  If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall take such action as it deems appropriate to
have the instrument  corrected.  Neither the Trustee, nor the Fiscal Agent shall
be  responsible  for the  accuracy  or content of any  resolution,  certificate,
statement, opinion, report, document, order or other instrument furnished by the
Depositor,  the Master Servicer or the Special  Servicer or any other person and
accepted by the Trustee in good faith, pursuant to this Agreement.

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

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

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

     (iii) The Trustee shall not be personally liable with respect to any action
taken,  suffered or omitted to be taken by it in good faith in  accordance  with
the direction of Holders of


                                      151
<PAGE>

Certificates entitled to at least 25% of the Voting Rights relating to the time,
method and place of conducting any  proceeding  for any remedy  available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this
Agreement.

     SECTION 8.02 Certain Matters Affecting the Trustee.

     Except as otherwise provided in Section 8.01:

     (i) The Trustee and the Fiscal  Agent may rely upon and shall be  protected
in acting or refraining from acting upon any resolution,  Officer's Certificate,
certificate  of  auditors  or  any  other  certificate,  statement,  instrument,
opinion, report, notice, request, consent, order, appraisal, bond or other paper
or document  reasonably  believed by it to be genuine and to have been signed or
presented by the proper party or parties;

     (ii) The Trustee  and the Fiscal  Agent may  consult  with  counsel and the
written  advice of such  counsel or any  Opinion  of  Counsel  shall be full and
complete authorization and protection in respect of any action taken or suffered
or omitted by it hereunder  in good faith and in  accordance  therewith  and the
expense of such  consultation  with counsel shall be reimbursable  under Section
8.05(b) hereof;

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

     (iv)  Neither the Trustee nor the Fiscal Agent shall be  personally  liable
for any action  reasonably  taken,  suffered  or omitted by it in good faith and
believed by it to be  authorized  or within the  discretion  or rights or powers
conferred upon it by this Agreement;

     (v) Prior to the occurrence of an Event of Default  hereunder and after the
curing of all Events of Default which may have  occurred,  the Trustee shall not
be bound to make any  investigation  into the  facts or  matters  stated  in any
resolution,   certificate,   statement,  instrument,  opinion,  report,  notice,
request,  consent,  order,  approval,  bond or other paper or  document,  unless
requested  in writing to do so by Holders of  Certificates  entitled to at least
50% of the  Voting  Rights;


                                      152
<PAGE>

provided,  however,  that if the payment within a reasonable time to the Trustee
of the costs,  expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee,  not reasonably assured
to the Trustee by the  security  afforded to it by the terms of this  Agreement,
the Trustee may require  reasonable  indemnity against such expense or liability
as a condition to taking any such action;

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

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

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

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

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

     SECTION 8.04 Trustee and the Fiscal Agent May Own Certificates.

     Each of the Trustee and the Fiscal Agent, in their  individual or any other
capacity,  may become the owner or pledgee of Certificates  with the same rights
it would have if it were not Trustee or the Fiscal Agent.

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

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

     SECTION 8.06 Eligibility Requirements for Trustee and Fiscal Agent.

     The Trustee hereunder shall at all times be an association or a corporation
organized and doing  business  under the laws of the United States of America or
any State  thereof or the  District of Columbia,  authorized  under such laws to
exercise  trust  powers,  having a  combined  capital  and  surplus  of at least
$100,000,000  and  subject to  supervision  or  examination  by federal or state
authority.  If such association or corporation publishes reports of condition at
least  annually,  pursuant  to  law  or to the  requirements  of  the  aforesaid
supervising  or examining  authority,  then for the purposes of this Section the
combined capital and surplus of such association or corporation  shall


                                      154
<PAGE>

be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published.  The long-term  unsecured debt  obligations of
the Trustee shall at all times be rated not less than "Aa2" by Moody's,  "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 if and for so long as a Fiscal Agent is  appointed  and acting
hereunder,  at least investment grade by each Rating Agency (or, if not rated by
FITCH  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);  provided,  that  either the  Trustee or the Fiscal
Agent shall at all times be an institution whose long term senior unsecured debt
is rated  not less  than "AA" by  Standard  & Poor's  "Aa2" by Moody and "AA" by
FITCH  IBCA or such  other  rating  as shall not  result  in the  qualification,
downgrade or withdrawal  of any of the ratings then  assigned to the  respective
Classes of Certificates,  as confirmed in writing by each Rating Agency. In case
at any time the  Trustee or the  Fiscal  Agent  shall  cease to be  eligible  in
accordance with the provisions of this Section,  the Trustee or the Fiscal Agent
shall resign  immediately in the manner and with the effect specified in Section
8.07;  provided  that if the Trustee  shall cease to be so eligible  because its
combined capital and surplus is no longer at least $100,000,000 or its long-term
unsecured debt rating no longer conforms to the  requirements of the immediately
preceding  sentence,  and if the Trustee proposes to the other parties hereto to
enter into an agreement with (and reasonably  acceptable to) each of them or the
Trustee  appoints  a fiscal  agent,  and if in light of such  agreement  or such
appointment,  the Trustee's  continuing  to act in such  capacity  would not (as
evidenced in writing by each rating  Agency) cause any Rating Agency to qualify,
downgrade or withdraw any rating assigned  thereby to any Class of Certificates,
then upon the execution and delivery of such agreement or the  effectiveness  of
such appointment,  the Trustee shall not be required to resign, and may continue
in such  capacity,  for so long as none of the  ratings  assigned  by the Rating
Agencies to the Certificates is adversely  affected thereby.  The corporation or
association  serving as Trustee may have normal banking and trust  relationships
with the  Depositor,  the  Master  Servicer,  the  Special  Servicer  and  their
respective Affiliates.

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

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

     (b) If at any time the  Trustee or Fiscal  Agent shall cease to be eligible
in accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor


                                      155
<PAGE>

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

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

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

     SECTION 8.08 Successor Trustee and the Fiscal Agent.

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


                                      156
<PAGE>

and to enable the successor trustee and fiscal agent, if applicable,  to perform
its obligations hereunder.

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

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

     SECTION 8.09 Merger or Consolidation of Trustee and the Fiscal Agent.

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

     SECTION 8.10 Appointment of Co-Trustee or Separate Trustee.

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

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


                                      157
<PAGE>

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. 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.



                                      158

     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

agreement or other  instrument  to which it is a party or which is applicable to
it or any of its assets.

the Special  Servicer,  the Master  Servicer,  the  Trustee  and the  Depositor,
constitutes  a  valid,  legal  and  binding  obligation  of  the  Fiscal  Agent,

                                   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,  the Fiscal Agent and the Trustee (other than the obligations
of the  Trustee  to  provide  for and make  payments  to  Certificateholders  as
hereafter set forth) shall  terminate upon payment (or provision for payment) to
the  Certificateholders  of all amounts  held by or on behalf of the Trustee and
required  hereunder to be so paid on the Distribution Date following the earlier
to occur of (i) the  purchase  by the Master  Servicer or the  Depositor  of all
Mortgage  Loans  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


                                      164
<PAGE>

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.

     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).

     shall satisfy all  requirements  of a qualified  liquidation  under Section
     860F of the Code and any regulations thereunder;

          (ii) during such 90-day liquidation period and at or prior to the time
     of making of the final payment on the Certificates,  the Trustee shall sell
     all of the assets of REMIC I to the Master  Servicer or the  Depositor,  as
     applicable, for cash; and

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

     (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.

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  as  provided  in  Section   5.02(d)(iii),   (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,


                                      167
<PAGE>

title,  address  and  telephone  number  of the  person  who  will  serve as the
representative of each of REMIC I, REMIC II and REMIC III.

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



                                      168

     (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 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 Fiscal  Agent,  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


                                      169
<PAGE>

10.01(f),  cause  REMIC  I,  REMIC  II or REMIC  III to be  subject  to a tax on
"prohibited transactions" or "contributions" pursuant to the REMIC Provisions.

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

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

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

     SECTION 10.03 Grantor Trust Administration.

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

     (b) The  Trustee  shall pay out of its own funds  any and all  routine  tax
administration  expenses of the Trust Fund  incurred with respect to the Grantor
Trust (but not including any professional  fees or expenses related to audits or
any  administrative or judicial  proceedings with respect to the Trust Fund that
involve  the  Internal   Revenue   Service  or  state  tax   authorities   which
extraordinary  expenses shall be payable or reimbursable to the Trustee from the
Trust Fund unless otherwise provided in Section 10.02(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


                                      170

Provisions or other  compliance  guidance issued by the Internal Revenue Service
or any state or local taxing authority.

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

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

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

     (i) to cure any ambiguity,

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

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

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

     (v) to modify, eliminate or add to the provisions of Section 5.02(d) or any
other  provision  hereof  restricting  transfer of the Residual  Certificates by
virtue of their being the REMIC "residual  interests," provided that such change
shall not, as evidenced by an Opinion of Counsel, cause either the Trust Fund or
any of the  Certificateholders  (other than the  transferor)  to be subject to a
federal tax caused by a transfer to a Person that is not a United  States Person
and a Permitted Transferee, or

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

<PAGE>

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

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

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

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

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

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

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

     (e) It shall not be necessary for the consent of  Certificateholders  under
this Section 11.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining  such consents and of evidencing  the  authorization  of the
execution  thereof by  Certificateholders  shall be  subject to such  reasonable
regulations as the Trustee may prescribe.

     (f) The Trustee may but shall not be obligated to enter into any  amendment
pursuant to this Section that affects its rights,  duties and  immunities  under
this Agreement or otherwise.

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

     SECTION 11.02 Recordation of Agreement; Counterparts.

     (a) To the extent permitted by applicable law, this Agreement is subject to
recordation in all appropriate  public offices for real property  records in all
the  counties  or other  comparable  jurisdictions  in  which  any or all of the

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

     (b) For the purpose of  facilitating  the  recordation of this Agreement as
herein  provided  and  for  other  purposes,  this  Agreement  may  be  executed

the same instrument.

     SECTION 11.03 Limitation on Rights of Certificateholders.

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

provided  for  herein) or in any manner  otherwise  control  the  operation  and
management  of the Trust Fund, or the  obligations  of the parties  hereto,  nor

this Agreement, such Holder previously shall have given to the Trustee a written
notice of default  hereunder,  and of the continuance  thereof,  as hereinbefore
provided,  and unless also  (except in the case of a default by the Trustee) the
Holders of Certificates of any Class evidencing not less than 25% of the related

suit or proceeding  in its own name as Trustee  hereunder and shall have offered
to the Trustee such  reasonable  indemnity as it may require  against the costs,
expenses and liabilities to be incurred therein or thereby, and the Trustee, for
60 days after its receipt of such notice, request and offer of indemnity,  shall
have neglected or refused to institute any such action, suit or proceeding.  The

may be incurred therein or hereby. It is understood and intended,  and expressly
covenanted by each Certificateholder with every other  Certificateholder and the
Trustee, that no one or more Holders of Certificates shall have any right in any
manner  whatsoever  by virtue of any  provision  of this  Agreement  to  affect,
disturb  or  prejudice   the  rights  of  the  Holders  of  any  other  of  such

other such Holder,  which  priority or preference is not otherwise  provided for
herein,  or to  enforce  any right  under this  Agreement,  except in the manner
herein  provided  and  for  the  equal,   ratable  and  common  benefit  of  all
Certificateholders. For the protection and enforcement of the provisions of this
Section  11.03(c),  each and every  Certificateholder  and the Trustee  shall be
entitled to such relief as can be given either at law or in equity.

     SECTION 11.04 GOVERNING LAW.

                                                                  Execution Copy

                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of May 25, 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)  Column  Financial,  Inc.
("Column")  pursuant to, and for the  consideration  described  in, the Mortgage
Loan  Purchase  Agreement,  dated as of May 25,1999 (the "Column  Mortgage  Loan
Purchase  Agreement")  between the  Purchaser and Column,  (ii) German  American
Capital Corporation ("GACC"),  pursuant to, and for the consideration  described
in, the Mortgage  Loan Purchase  Agreement,  dated as of May 25, 1999 (the "GACC
Mortgage  Loan  Purchase  Agreement"),  between the Purchaser and GACC and (iii)
Goldman Sachs Mortgage Company ("GSMC")  pursuant to, and for the  consideration
described  in, the Mortgage Loan  Purchase  Agreement,  dated as of May 25, 1999
(the "GSMC  Mortgage  Loan Purchase  Agreement")  between the Purchaser and GSMC
(the mortgage loans  purchased by the Purchaser  under the Column  Mortgage Loan
Purchase  Agreement,  the GACC  Mortgage  Loan  Purchase  Agreement and the GSMC
Mortgage Loan  Purchase  Agreement,  the "Other  Mortgage  Loans").  The Seller,
Column,  GACC  and GSMC  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,  Moody's Investors  Service,  Inc. 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 June 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"), LaSalle Bank National Association, as trustee
(in such  capacity,  the  "Trustee")  and ABN AMRO  Bank N.V.  as fiscal  agent.
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.

<PAGE>

     The Purchaser  intends to sell the Class A-1,  Class A-2, Class B, Class C,
Class D, Class E, Class F, Class G and Class X Certificates to Donaldson, Lufkin
& Jenrette  Securities  Corporation,  Deutsche Bank Securities Inc. and Goldman,
Sachs  &  Co.,  (together,  the  "Underwriters")  pursuant  to  an  underwriting
agreement dated the date hereof (the  "Underwriting  Agreement").  The Purchaser
intends  to sell the Class F, Class G, Class H, Class J, Class K, Class L, Class
M and Class N Certificates  to Commercial  Asset Trading Inc. (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 Credit Suisse
First Boston Corporation (in such capacity, an "Initial  Purchaser").  The Class
H, Class J, Class K, Class L, Class M, Class N, 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 May 25, 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 June 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  $[___________]  subject to a
variance of plus or minus 5%. The purchase price for the Mortgage Loans shall be
$________________.

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


                                       2
<PAGE>

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. 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


                                       3
<PAGE>

(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  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 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


                                       5
<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
     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


                                       6
<PAGE>

     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-7  through  A-9,
     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--The Mortgage Pool", "Risk Factors" and "Description
     of the Mortgage  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.

          (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.

          (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 Initial
     Purchasers  and their  respective  affiliates,  that may be entitled to any
     commission  or  compensation  in


                                       8
<PAGE>

     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
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


                                       9
<PAGE>

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.

     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


                                       10
<PAGE>

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 Mayer, Brown & Platt, 1675 Broadway,  New York, New York 10019
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;

               (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


                                       11
<PAGE>

          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)  Neither the  Underwriting  Agreement  nor 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;

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 -- The Mortgage Pool", "Risk Factors" and/or  "Description
of the  Mortgage  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 prospectus dated November 5,
1998,  as  supplemented  by the  prospectus  supplement  dated May 25, 1999 (the
"Prospectus Supplement"), relating to the Registered Certificates;  "Memorandum"
shall mean the private placement  memorandum dated May 25, 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


                                       13
<PAGE>

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 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


                                       14
<PAGE>

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

registered  mail,  postage  prepaid,  by overnight mail or courier  service,  or
transmitted  by facsimile and confirmed by a similar mailed  writing,  if to the
Purchaser, addressed to GMAC Commercial Mortgage Securities, Inc. at 650 Dresher

Corporation,  or to such  other  address or  facsimile  number as the Seller may
designate in writing to the Purchaser.

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.

                                    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.


                                      C-1
<PAGE>

     (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  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


                                      C-2
<PAGE>

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 under an "all risk" insurance policy against loss by hazards of extended
coverage in an amount (subject to a customary  deductible) at least equal to the
full insurable  replacement cost of the  improvements  located on such Mortgaged
Property,   which  policy  contains   appropriate   endorsements  to  avoid  the
application of coinsurance and does not permit  reduction in insurance  proceeds
for depreciation.  If any portion of the improvements upon the related Mortgaged
Property was, at the time of the  origination  of such Mortgage Loan, in a flood
zone  area as  identified  in the  Federal  Register  by the  Federal  Emergency
Management  Agency as a 100 year flood zone or special  hazard  area,  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,  or (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 workers' compensation
insurance (if applicable),  comprehensive general liability insurance in amounts
generally  required by the Seller, and at least twelve 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 names the
holder  of the  Mortgage  as an  additional  insured  or  contains  a  mortgagee
endorsement  naming the holder of the Mortgage as loss payee and 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.


                                      C-3
<PAGE>

     (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  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
[______] 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,  permits and  authorizations  required


                                      C-5

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 each  Mortgage Loan which is a
Credit Lease Loan:


                                      C-6
<PAGE>

     (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 either (i) fully  amortizes  over its original term and has
          no  "balloon"  payment of rent due under the related  Credit  Lease or
          (ii) is a Balloon Loan,  for which a residual value  insurance  policy
          has been  obtained  that  requires  the  payment of an amount at least
          equal to the Balloon Payment due on the related Maturity Date;

     (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;

     (I)  For  each  Credit  Lease  Loan  under  which  a  Credit  Lease  may be
          terminated upon the occurrence of a casualty or condemnation,  a lease
          enhancement insurance policy has been obtained that requires upon such
          termination  the payment in full 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,  except to the extent of  coverage  provided by the related
          lease enhancement insurance policy;

     (J)  The terms of any guaranty of the payment and  performance  obligations
          of the tenant under any Credit Lease are unconditional and provide for
          guaranty of payment and not of collection; and

     (K)  The Borrower  under the Mortgage  Loan  identified  as GMACCM Loan No.
          4210 in the  Mortgage  Loan  Schedule  (a) does not have any  material
          monetary obligations under the Credit Lease other than those for which
          the related tenant is required to reimburse the Borrower and indemnity
          obligations  for  liabilities  imposed by applicable law, (b) does not
          have any  material  non-monetary  obligations  under the Credit  Lease
          except for the  delivery  of  possession  of the leased  property  and
          providing estoppel  certificates,  and (c) except for  representations
          qualified by its knowledge,  has not made any material  representation
          or  warranty  under the Credit  Lease that would  impose any  material
          monetary  obligation upon the Borrower or result in the termination of
          the Credit Lease.

     (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


                                      C-8
<PAGE>

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;

     (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  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


                                      C-9
<PAGE>

          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  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.


                                      C-10
<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 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 by the Mortgagor,  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 June 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) [Reserved]

     It is understood  and agreed that the  representations  and  warranties set
forth in this Exhibit C shall survive delivery of the respective  Mortgage Files
to the  Purchaser  and/or  the  Trustee  and shall  inure to the  benefit of the
Purchaser,  and its successors  and assigns  (including

                   FORM OF OPINION I OF COUNSEL TO THE SELLER

June 9, 1999

To: Persons on Annex A

Re: GMAC Commercial Mortgage Securities, Inc.
    Mortgage Pass-Through Certificates, Series 1999-C2

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-C2  (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 June 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,
LaSalle Bank, as trustee (the "Trustee") and ABN AMRO Bank N.V. as fiscal agent.

     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 May 25, 1999 (the "GMACCM Mortgage Loan Purchase
Agreement"),  between the Company and the Seller.  Certain of the Mortgage Loans
were purchased by the Company from Column Financial,  Inc.  ("Column")  pursuant
to,  and  for  the  consideration  described  in,  the  Mortgage  Loan  Purchase
Agreement,  dated  as of May  25,  1999  (the  "Column  Mortgage  Loan  Purchase
Agreement")  between the Company and Column.  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  May  25,  1999  (the  "GACC  Mortgage  Loan  Purchase
Agreement"),  between the Company and GACC. Mortgage Company ("GSMC"),  pursuant
to,  and  for  the  consideration  described  in,  the  Mortgage  Loan  Purchase
Agreement,  dated  as  of  May  25,  1999  (the  "GSMC  Mortgage  Loan  Purchase
Agreement"),  between the Company and GSMC. 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,
Class E,  Class F and  Class G  Certificates  to  Donaldson,  Lufkin &  Jenrette
Securities Corporation,  Deutsche Bank Securities Inc. and Goldman, Sachs & Co.,
as the underwriters (the


                              Exhibit D-3A - Page 1
<PAGE>

"Underwriters")  named in the Underwriting  Agreement,  dated as of May 25, 1999
(the  "Underwriting  Agreement"),   among  the  Company,  the  Seller,  and  the
Underwriters.  The Company  sold the Class H, Class J, Class K, Class L, Class M
and Class N Certificates to Commercial Asset Trading Inc.  ("CATI")  pursuant to
the Certificate  Purchase Agreement,  dated as of May 25, 1999 (the "Certificate
Purchase  Agreement"),  between the Company and CATI. The Company sold the Class
R-I,  Class R-II and Class R-III  Certificates  to Credit  Suisse  First  Boston
Corporation.

     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


                             Exhibit D-3A - Page 2
<PAGE>

proceeding  in  equity  or  at  law,  and  (iii)  public  policy  considerations
underlying  the  securities   laws,  to  the  extent  that   suchpublic   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 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 Mayer, Brown & Platt, 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,

Re: GMAC Commercial Mortgage Securities, Inc.,
    Mortgage Pass-Through Certificates, Series 1999-C2

Ladies and Gentlemen:

     This  opinion  is being  provided  to you by the  undersigned,  as  special
counsel to GMAC Commercial Mortgage Corporation ("GMACCM"),  pursuant to Section
8(e) of the Mortgage  Loan Purchase  Agreement,  dated May 25, 1999 (the "GMACCM
Mortgage Loan Purchase Agreement"), between GMAC Commercial Mortgage Securities,
Inc.  (the  "Purchaser")  and  GMACCM  as the  Seller,  (in  such  capacity  the
"Seller"),  relating  to the sale by the Seller of certain  mortgage  loans (the
"GMACCM Mortgage Loans"),  and relating to the Certificates sold pursuant to the
Underwriting Agreement, dated as of May 25, 1999 (the "Underwriting Agreement"),
between the Purchaser and Donaldson,  Lufkin & Jenrette Securities  Corporation,
Deutsche  Bank  Securities  Inc. and  Goldman,  Sachs & Co, and issued under the
Pooling  and  Servicing  Agreement,  dated as of June 1, 1999,  among  GMACCM as
special  servicer  and  master  servicer  (in such  respective  capacities,  the
"Special  Servicer" and the "Master  Servicer"),  the  Purchaser,  as depositor,
LaSalle Bank National  Association,  as trustee and ABN AMRO Bank N.V. as fiscal
agent (the  "Pooling  and  Servicing  Agreement"  and  together  with the GMACCM
Mortgage Loan  Purchase  Agreement,  the  "Agreements").  Capitalized  terms not
otherwise defined herein have the meanings assigned to them in the Agreements.

     In connection with the transactions described above, certain mortgage loans
(the  "GACC  Mortgage  Loans")  were sold to the  Purchaser  by German  American
Capital Corporation ("GACC"),  pursuant to the Mortgage Loan Purchase Agreement,
dated as of May


                              Exhibit D-3B - Page 1
<PAGE>

25, 1999 (the "GACC  Mortgage Loan Purchase  Agreement"),  between the Purchaser
and GACC,  certain other mortgage  loans (the "GSMC Trust Mortgage  Loans") were
sold to the Purchaser by Goldman Sachs Mortgage Company("GSMC"), pursuant to the
Mortgage Loan Purchase  Agreement,  dated as of May 25, 1999 (the "GSMC Mortgage
Loan Purchase  Agreement"),  between the  Purchaser and GSMC,  and certain other
mortgage  loans (the  "Column  Mortgage  Loans")  were sold to the  Purchaser by
Column  Financial,  Inc.  ("Column"),  pursuant to the  Mortgage  Loan  Purchase
Agreement,  dated  as of May  25,  1999  (the  "Column  Mortgage  Loan  Purchase
Agreement"), between the Purchaser and Column.

     In rendering this opinion, we have examined and relied upon executed copies
of the Agreements and originals or copies,  certified or otherwise identified to
our  satisfaction,  of such  certificates  and other documents as we have deemed
appropriate  for the purposes of rendering  this  opinion.  We have examined and
relied upon, among other things,  the documents and opinions delivered to you at
the closing being held today  relating to the  Certificates,  as well as (a) the
Prospectus  and the  Memorandum,  (b) an executed copy of the GACC Mortgage Loan
Purchase  Agreement,  the GMACCM  Mortgage  Loan  Purchase  Agreement,  the GSMC
Mortgage Loan Purchase Agreement and the Column Mortgage Loan Purchase Agreement
and (c) an executed copy of the Pooling and Servicing Agreement.

     In conducting our examination, we have assumed, without investigation,  the
legal capacity of all natural  persons,  the genuineness of all signatures,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original documents of all documents  submitted to us as certified or photostatic
copies and the authenticity of the originals of such latter documents.  We have,
with your  permission,  also relied upon the  opinions of even date  herewith of
Maria  Corpora-Buck,  Esq.,  General  Counsel to GMACCM,  and Severson & Werson,
special California counsel to GMACCM, addressed to you. As to any facts material
to the opinions  expressed  herein which were not  independently  established or
verified,  we have relied upon oral or written statements and representations of
officers and other representatives of GMACCM and others.

     We are members of the bar of the State of New York and do not purport to be
experts on or to express any opinion  herein  concerning any laws other than the
laws of the  State of New York and the  federal  laws of the  United  States  of
America. We express no opinion herein as to the laws of any other jurisdiction.

     Based upon the matters stated herein and upon such investigation as we have
deemed  necessary,  we are of the  opinion  that the  Agreements  have been duly
authorized,  executed  and  delivered  by GMACCM  and,  upon due  authorization,
execution and delivery by the Purchaser, will each constitute a valid, legal and
binding agreement of GMACCM,  enforceable  against GMACCM in accordance with its
respective  terms,  except as  enforceability  may be limited by (a) bankruptcy,
insolvency,  liquidation,  receivership,  moratorium,  reorganization  or  other
similar  laws  relating to or affecting  the  enforcement  of  creditors  rights
generally and (b) general principles of equity, whether enforcement is sought in
a proceeding in equity or at law.


                              Exhibit D-3B - Page 2
<PAGE>

     In rendering the opinions  expressed above, we express no opinion regarding
any severability  provision in the Agreements or regarding the legal,  valid and
binding effect or the  enforceability  of any  indemnification  provision in the
Agreements to the extent that any such provisions may be deemed to cover matters
under the federal  securities laws. The opinions  expressed above are subject to
the  further  qualification  that  certain  of the  remedial  provisions  in the
Agreements may be limited or rendered  ineffective or  unenforceable in whole or
in part  under  the laws of the  State of New York  (but the  inclusion  of such
provisions does not make the remedies provided by the Agreements  inadequate for
the practical  realization  of the rights and benefits  purported to be provided
thereby, except for the economic consequences of procedural or other delay).

     We have not ourselves checked the accuracy or completeness of, or otherwise
independently verified, the information furnished with respect to the Prospectus
Supplement  or the  Memorandum.  In  addition,  as you are aware,  with  limited
exception,  we did not  examine or review the  Mortgage  Files  although  we did
review the asset summaries (the "GMACCM Asset Summaries") furnished and prepared
by GMACCM  with  respect  to the  GMACCM  Mortgage  Loans  sold under the GMACCM
Mortgage Loan Purchase  Agreement,  the GACC Mortgage  Loans sold under the GACC
Mortgage Loan Purchase  Agreement,  the GSMC Mortgage  Loans sold under the GSMC
Mortgage Loan Purchase  Agreement and the Column  Mortgage  Loans sold under the
Column Mortgage Loan Purchase Agreement (collectively, the "Mortgage Loans"). We
did  not,   however,   check  the  accuracy  or  completeness  of  or  otherwise
independently  verify the information  contained in the GMACCM Asset  Summaries.
Moreover,  we note that we were advised by GMACCM in connection  with our review
of the GMACCM Asset  Summaries  that such GMACCM Asset  Summaries were summaries
only, and in certain instances being continually  updated and corrected and were
not  intended to be relied on for a complete  legal  description  of each GMACCM
Mortgage Loan.

     In  the  course  of the  preparation  by the  Purchaser  of the  Prospectus
Supplement and the Memorandum,  we have participated in conferences with certain
officers  of  GMACCM,   the  Purchaser,   counsel  to  the  Purchaser  and  your
representatives,  during which the contents of the Prospectus Supplement and the
Memorandum  and related  matters  were  discussed  and, at your  request we have
reviewed the information  contained in the Prospectus Supplement (other than the
information  presented  in tabular  form)  under the  headings  "Summary  -- The
Mortgage  Pool,"  "Risk  Factors"  and/or  "Description  of the  Mortgage  Pool"
relating to GMACCM,  the Purchaser  and the Mortgage  Loans  (collectively,  the
"Selected  Information").  On the basis of the  discussions  and limited  review
referred  to above,  although  we are not  passing  upon,  and do not assume any
responsibility  for, the accuracy,  completeness  or fairness of the  statements
contained  in  the  Prospectus  Supplement  and  the  Memorandum,   and  without
independent check or verification of the Selected  Information except as stated,
no facts have come to our  attention  that have  caused us to  believe  that the
Selected  Information  set  forth in either  the  Prospectus  Supplement  or the
Memorandum  (other than financial and statistical  data included or not included
therein  or  incorporated  by  reference  therein,  as to  which we  express  no
opinion),  as of its issue date,  contained  any untrue  statement of a material
fact or omitted to


                              Exhibit D-3B - Page 3
<PAGE>

state a material fact necessary to make the statements  therein, in the light of
the circumstances under which they were made, not misleading.

     Whenever our opinion  with respect to the  existence or absence of facts is
indicated to be based on our  knowledge or  awareness,  we are  referring to the
actual knowledge of the Mayer,  Brown & Platt attorneys who have represented you
in connection with the  transactions  contemplated by the Agreements.  Except as
expressly set forth herein, we have not undertaken any independent investigation
to determine  the  existence or absence of such facts and no inference as to our
knowledge  concerning  such  facts  should  be drawn  from the  fact  that  such
representation has been undertaken by us.

     This  letter is limited to the  specific  issues  addressed  herein and the
opinion  rendered above is limited in all respects to laws and facts existing on
the date hereof.  By rendering  this opinion,  we do not undertake to advise you
with  respect  to any other  matter or of any change in such laws or facts or in
the interpretations of such laws which may occur after the date hereof.

     We are furnishing this opinion to you solely for your benefit. This opinion
is not to be used,  circulated,  quoted or  otherwise  referred to for any other
purpose,  except that the persons  listed on Exhibit A hereto may rely upon this
opinion in connection  with their rating of the  Certificates to the same extent
as if this opinion had been addressed to them.

                                                Very truly yours,


                                                Mayer, Brown & Platt


                              Exhibit D-3B - Page 4



                                                                  EXECUTION COPY

                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of May 25, 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,  Moody's Investors  Service,  Inc. 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 June 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 LaSalle Bank 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, Class F, Class G and Class X Certificates to Donaldson, Lufkin
& Jenrette  Securities  Corporation,  Deutsche Bank Securities Inc. and Goldman,
Sachs & Co. (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  The Purchaser intends to
sell the Class H, Class J, Class K, Class L, Class M and Class N Certificates to
Commercial  Asset  Trading  Inc.  (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 Credit  Suisse  First  Boston
Corporation in such  capacity,  an "Initial  Purchaser").  The Class H, Class J,
Class K,  Class L, Class M,  Class N,  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 May 25, 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  June,  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 $__________, subject
to a variance of plus or minus 5%. The  purchase  price for the  Mortgage  Loans
shall be $__________.

     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 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 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 by
GMAC Commercial  Mortgage  Corporation.  On the Closing 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) 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

          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  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 or
     the financial condition of the Seller.

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  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) 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, the
party  discovering  such breach  shall give prompt  written  notice to the other

     and the  performance and compliance with the terms of this Agreement by the

     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 Purchaser to carry out the transactions
     contemplated by this Agreement.

          (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,  (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  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.

     agent or other person, other than the Seller, the Underwriters, 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

         Re: GMAC Commercial Mortgage Securities, Inc.,
             Mortgage Pass-Through Certificates, Series 1999-C2

Ladies and Gentlemen:

     I am 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-C2  (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 June 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 LaSalle Bank National Association, as trustee (the "Trustee").

     Certain of the  Mortgage  Loans were  purchased by the  Depositor  from the
Seller,  pursuant to, and for the consideration  described in, the Mortgage Loan
Purchase  Agreement,  dated as of May 25,  1999  (the  "Mortgage  Loan  Purchase
Agreement"),  between  the  Seller and the  Depositor.  In  connection  with the
transactions  described  above,  the  Seller  and  GMACCM  have  entered  into a
Supplemental Agreement, dated as of May 25, 1999 (the "Supplemental Agreement"),
in order to facilitate such  transactions and in contemplation of the assignment
by the Seller to the Depositor of all of its right, title and interest in and to
the Supplemental Agreement. The Mortgage Loan


                                      C-3-1
<PAGE>

Purchase 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.

     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 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 corporate power and authority, 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


                                      C-3-2
<PAGE>

          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.

     3.   No consent, approval, authorization or order of a State of New York or
          federal  court or  governmental  agency  or body is  required  for the
          consummation  by the Seller of the  transactions  contemplated  by the
          terms  of  the  Agreements,  except  for  those  consents,  approvals,
          authorizations or orders which previously have been obtained.

     4.   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 of New York or
          federal statute or regulation or conflict with or result in a material
          breach or violation of any order or regulation of any state 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 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,


                                      C-3-3



                                                                  EXECUTION COPY

                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective  as of May 25, 1999,  between  Column  Financial,  Inc. 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,  Moody's Investors  Service,  Inc. 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 June 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 LaSalle Bank 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, Class F, Class G and Class X Certificates to Donaldson, Lufkin
& Jenrette  Securities  Corporation,  Deutsche Bank Securities Inc. and Goldman,
Sachs & Co. (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  The Purchaser intends to
sell the Class H, Class J, Class K, Class L, Class M and Class N Certificates to
Commercial  Asset  Trading  Inc.  (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 Credit  Suisse  First  Boston
Corporation in such  capacity,  an "Initial  Purchaser").  The Class H, Class J,
Class K,  Class L, Class M,  Class N,  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:

purchase and sale of the Mortgage Loans shall take place on May 25, 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

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 $__________, subject
to a variance of plus or minus 5%. The  purchase  price for the  Mortgage  Loans
shall be $__________.

       SECTION 2. Conveyance of Mortgage Loans.

       (a)  Effective  as of the Closing  Date,  subject  only to receipt by the

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 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 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 by
GMAC Commercial  Mortgage  Corporation.  On the Closing 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) 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


                                       2

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.

     (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  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.

     (b) 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  Delaware,  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

<PAGE>

     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 or
     the financial condition of the Seller.

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  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) 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, the
party  discovering  such breach  shall give prompt  written  notice to the other

     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 Purchaser to carry out the transactions
     contemplated by this Agreement.

          (iii) The Purchaser has the full power and authority to enter into and
     consummate  all  transactions  contemplated  by this  Agreement,  has  duly

     creditors' rights generally,  (B) general principles of equity,  regardless

     enforceability  of the provisions of this Agreement that purport to provide
     indemnification for securities laws liabilities.

     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

     faith and reasonable judgment, is likely to materially and adversely affect

     agent or other person, other than the Seller, the Underwriters, the Initial
     Purchasers  and their  respective  affiliates,  that may be entitled to any

     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

     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.

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-C2

Ladies and Gentlemen:

     I am Counsel to Column Financial,  Inc. (the "Seller"). In that capacity, I
am familiar  with the issuance of certain  Mortgage  Pass-Through  Certificates,
Series 1999-C2 (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
June 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
LaSalle Bank National Association, as trustee (the "Trustee").

     Certain of the  Mortgage  Loans were  purchased by the  Depositor  from the
Seller,  pursuant to, and for the consideration  described in, the Mortgage Loan
Purchase  Agreement,  dated as of May 25,  1999  (the  "Mortgage  Loan  Purchase
Agreement"),  between  the  Seller and the  Depositor.  In  connection  with the
transactions  described  above,  the  Seller  and  GMACCM  have  entered  into a
Supplemental Agreement, dated as of May 25, 1999 (the "Supplemental Agreement"),
in order to facilitate such  transactions and in contemplation of the assignment
by the Seller to the Depositor of all of its right, title and interest in and to
the Supplemental Agreement. The Mortgage Loan


                                     C-3-1
<PAGE>

Purchase 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.

     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  Georgia,  the  corporate  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 Georgia 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 Delaware
          and has the requisite corporate power and authority, 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


                                      C-3-2
<PAGE>

          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.

     3.   No consent, approval,  authorization or order of a State of Georgia or
          federal  court or  governmental  agency  or body is  required  for the
          consummation  by the Seller of the  transactions  contemplated  by the
          terms  of  the  Agreements,  except  for  those  consents,  approvals,
          authorizations or orders which previously have been obtained.

     4.   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 of  Georgia  or
          federal statute or regulation or conflict with or result in a material
          breach or violation of any order or regulation of any state 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 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,


                                      C-3-3



                                                                  EXECUTION COPY

                        MORTGAGE LOAN PURCHASE AGREEMENT


     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and

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,  Moody's Investors  Service,  Inc. 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 June 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 LaSalle Bank 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, Class F, Class G and Class X Certificates to Donaldson, Lufkin
& Jenrette  Securities  Corporation,  Deutsche Bank Securities Inc. and Goldman,
Sachs & Co. (together, the "Underwriters") pursuant to an underwriting agreement
dated the date hereof (the "Underwriting  Agreement").  The Purchaser intends to
sell the Class H, Class J, Class K, Class L, Class M and Class N Certificates to
Commercial  Asset  Trading  Inc.  (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 Credit  Suisse  First  Boston
Corporation in such  capacity,  an "Initial  Purchaser").  The Class H, Class J,
Class K,  Class L, Class M,  Class N,  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 May 25, 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  June,  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 $__________, subject
to a variance of plus or minus 5%. The  purchase  price for the  Mortgage  Loans
shall be $__________.

     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 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 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 by
GMAC Commercial  Mortgage  Corporation.  On the Closing 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) 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


                                       2
<PAGE>

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.

     (d) The Seller and the Purchaser  intend the transfer of the Mortgage Loans
hereunder to be a true sale by the Seller to the Purchaser  that is absolute and
irrevocable  and that provides the  Purchaser  with full control of the Mortgage
Loans.

     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) Reserved.

     (b) The Seller,  as of the date hereof,  hereby represents and warrants to,

          (i) The  Seller  is a limited  partnership,  duly  organized,  validly
     existing and in good standing  under the laws of the State of New York, 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

     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 or
     the financial condition of the Seller.

          (vii) The  Seller has not dealt with any  broker,  investment  banker,
     agent or other person,  other than the  Purchaser,  the  Underwriters,  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) 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, the
party  discovering  such breach  shall give prompt  written  notice to the other

     and the  performance and compliance with the terms of this Agreement by the

     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 Purchaser to carry out the transactions
     contemplated by this Agreement.

          (iii) The Purchaser has the full power and authority to enter into and
     consummate  all  transactions  contemplated  by this  Agreement,  has  duly

     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  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

     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.

     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

     the performance by the Purchaser under this Agreement.

     Re: GMAC Commercial Mortgage Securities, Inc.,
         Mortgage Pass-Through Certificates, Series 1999-C2

Ladies and Gentlemen:

     I am Counsel to Goldman  Sachs  Mortgage  Company (the  "Seller").  In that
capacity,  I am  familiar  with the  issuance of certain  Mortgage  Pass-Through
Certificates,   Series  1999-C2  (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 June 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 LaSalle Bank National Association, as trustee (the "Trustee").

     Certain of the  Mortgage  Loans were  purchased by the  Depositor  from the
Seller,  pursuant to, and for the consideration  described in, the Mortgage Loan
Purchase  Agreement,  dated as of June 25,  1999 (the  "Mortgage  Loan  Purchase
Agreement"),  between  the  Seller and the  Depositor.  In  connection  with the
transactions  described  above,  the  Seller  and  GMACCM  have  entered  into a
Supplemental   Agreement,   dated  as  of  June  25,  1999  (the   "Supplemental
Agreement"),  in order to facilitate such  transactions  and in contemplation of
the  assignment  by the Seller to the  Depositor of all of its right,  title and
interest in and to the Supplemental Agreement. The Mortgage Loan


                                      C-3-1
<PAGE>

Purchase 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.

     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 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  formed  and is  validly  existing  as a  limited
          partnership  in good standing  under the laws of the State of New York
          and has the requisite corporate power and authority, 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


                                      C-3-2
<PAGE>

          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.

     3.   No consent, approval, authorization or order of a State of New York or
          federal  court or  governmental  agency  or body is  required  for the
          consummation  by the Seller of the  transactions  contemplated  by the
          terms  of  the  Agreements,  except  for  those  consents,  approvals,
          authorizations or orders which previously have been obtained.

     4.   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 of New York or
          federal statute or regulation or conflict with or result in a material
          breach or violation of any order or regulation of any state or federal
          court,  regulatory body,  administrative  agency or governmental  body
          having jurisdiction over the Seller.

                                                                  EXECUTION COPY

                             SUPPLEMENTAL AGREEMENT

     This Supplemental Agreement (this "Agreement"), is dated and effective as
of May 25, 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 to the Purchaser pursuant
to a certain Mortgage Loan Purchase Agreement (the "GACC Purchase Agreement"),
dated as of March 31, 1999.

     WHEREAS, the Purchaser intends to sell the mortgage loans as shown on
Exhibit A hereto (the "Mortgage Loans") to GMAC Commercial Mortgage Securities,
Inc. as Depositor, (the "Depositor") pursuant to a certain Mortgage Loan

Agreement") 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"). Certain classes of the Certificates will be rated by Standard &
Poor's Ratings Services, Moody's Investors Services, Inc. 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,

Certificates will be issued pursuant to a pooling and servicing agreement to be
dated as of May 1, 1999 (the "Pooling and Servicing Agreement"), among the
Depositor 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 LaSalle Bank 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).

     WHEREAS, the Depositor intends to sell the Class A-1, Class A-2, Class B,
Class C, Class D, Class E, Class F, Class G and Class X Certificates to
Donaldson, Lufkin & Jenrette Securities Corporation, Deutsche Bank Securities

Agreement"). The Depositor intends to sell the Class H, Class J, Class K, Class
L, Class M and Class N Certificates to GMACCM (in such capacity, an "Initial
Purchaser") pursuant to a Certificate Purchase Agreement dated as of the date
hereof (the "Certificate Purchase Agreement"). The Depositor intends to sell the
Class R-I, Class R-II and Class R-III Certificates to Credit Suisse First Boston
Corporation (in such capacity, an "Initial Purchaser").

     WHEREAS, each of the Seller and the Purchaser, in connection with the
transactions described above, desires to amend and supplement certain of the
provisions of the GACC Purchase Agreement as they relate to the Mortgage Loans
in order to facilitate such transactions

                                        1
<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 June 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 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 either the ability of the
              Seller to perform its obligations under this Agreement or the
              financial condition of the Seller.

       (vii)  The Seller has not dealt with any broker, investment banker, agent
              or other person, other than the Purchaser, the Underwriters, 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,


                                       3
<PAGE>

              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 by the
Purchaser, to such assignee. The representations, warranties and covenants set
forth in Section 2(a) shall, as between the Seller and the Purchaser,
supplement, and as between the Seller and any successors or assigns of the
Purchaser, replace and amend and restate in their entirety, the representations,
warranties and covenants of the Seller made pursuant to 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, in each case which materially and adversely
              affect the ability of the Purchaser to carry out the transactions
              contemplated by this Agreement.

       (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


                                       4
<PAGE>

              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 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 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.


                                       5
<PAGE>

     (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 the 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)   The Purchaser has full right and authority to sell, assign and
              transfer its interest in such Mortgage Loan;

       (iii)  The Purchaser has not 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 Purchaser's actual knowledge, without independent inquiry
              as to the provisions of the Mortgage Loans, there is no valid
              offset, defense or counterclaim to such Mortgage Loan arising out
              of the Purchaser's actions or holding of the Mortgage Loans; and

       (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;

provided  that,  with respect to the  representations  and warranties in clauses
(iii), (iv), (v) and (vi) above, such  representations and warranties cover only
actions  taken  directly by the  Purchaser  and its  Affiliates  or taken by the
Seller at the direction of the Purchaser.

     (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 interests of the Seller, the party discovering such breach shall
give prompt written notice to the other party hereto.


                                       6

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


                                       7
<PAGE>

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. 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 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 it 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 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 or replace any Mortgage Loan in accordance with Section 4(a) or 4(b)
or disputes its obligation to repurchase or replace 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


                                       8
<PAGE>

provided in this Section 4 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).


                                       9
<PAGE>

     (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, 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

SECTION 8. Indemnification.

joint or several, to which it


                                       10
<PAGE>

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
the Purchaser's representations or warranties contained in Section 3(b) of this
Agreement. This indemnity will be in addition to any liability which the
Purchaser may otherwise have.

     (b) The indemnity agreement contained in this Section 8 shall remain
operative and in full force and effect regardless of (i) any termination of this
Agreement, or (ii) any investigation made by any indemnified party.

SECTION 9. 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 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 10. 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 11. 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

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

                             MORTGAGE LOAN SCHEDULE


                                       A-1
<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 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,


                                      B-1
<PAGE>

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. 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).


                                      B-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 twelve 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.


                                      B-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
_________ Mortgage Loans as to which the interest of the related Mortgagor 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.


                                      B-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, permits and authorizations


                                      B-5
<PAGE>

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 each Mortgage Loan which is a
Credit Lease Loan:


                                      B-6
<PAGE>

     (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 either (i) fully amortizes over its original term and has
          no "balloon" payment of rent due under the related Credit Lease or
          (ii) is a Balloon Loan, for which a residual value insurance policy
          has been obtained that requires the payment of an amount at least
          equal to the Balloon Payment due on the related Maturity Date;

     (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;


                                      B-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;

     (I)  For each Credit Lease Loan under which a Credit Lease may be
          terminated upon the occurrence of a casualty or condemnation, a lease
          enhancement insurance policy has been obtained that requires upon such
          termination the payment in full 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, except to the extent of coverage provided by the related
          lease enhancement insurance policy;

     (J)  The terms of any guaranty of the payment and performance obligations
          of the tenant under any Credit Lease are unconditional and provide for
          guaranty of payment and not of collection; and

     (K)  The Borrower under the Mortgage Loan identified as GMACCM Loan No.
          4210 in the Mortgage Loan Schedule (a) does not have any material
          monetary obligations under the Credit Lease other than those for which
          the related tenant is required to reimburse the Borrower and indemnity
          obligations for liabilities imposed by applicable law, (b) does not
          have any material non-monetary obligations under the Credit Lease
          except for the delivery of possession of the leased property and
          providing estoppel certificates, and (c) except for representations
          qualified by its knowledge, has not made any material representation
          or warranty under the Credit Lease that would impose any material
          monetary obligation upon the Borrower or result in the termination of
          the Credit Lease.

     (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


                                      B-8
<PAGE>

"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;

     (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

                                      B-9
<PAGE>

          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 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-10
<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 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 May 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.

                             SUPPLEMENTAL AGREEMENT

     This Supplemental Agreement (this "Agreement"), is dated and effective as

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 Column Purchase Agreement.

     The parties hereto agree that, with respect to the Mortgage Loans only, the
Column Purchase Agreement is hereby amended to the extent that the provisions of
the Column Purchase Agreement are inconsistent with this Agreement.

SECTION 2. Representations, Warranties and Covenants of the Seller.

     (a) The Seller hereby makes, as of June 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.


                                       2
<PAGE>

       (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 either the ability of the
              Seller to perform its obligations under this Agreement or the
              financial condition of the Seller.

       (vii)  The Seller has not dealt with any broker, investment banker, agent
              or other person, other than the Purchaser, the Underwriters, 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,


                                       3
<PAGE>

              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 by the
Purchaser, to such assignee. The representations, warranties and covenants set
forth in Section 2(a) shall, as between the Seller and the Purchaser,
supplement, and as between the Seller and any successors or assigns of the
Purchaser, replace and amend and restate in their entirety, the representations,
warranties and covenants of the Seller made pursuant to Section 4.1(a) of the
Column 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 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, in each case which materially and adversely
              affect the ability of the Purchaser to carry out the transactions
              contemplated by this Agreement.

       (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


                                       4
<PAGE>

              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 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 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.


                                       5
<PAGE>

     (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 the 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)   The Purchaser has full right and authority to sell, assign and
              transfer its interest in such Mortgage Loan;

       (iii)  The Purchaser has not 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 Purchaser's actual knowledge, without independent inquiry
              as to the provisions of the Mortgage Loans, there is no valid
              offset, defense or counterclaim to such Mortgage Loan arising out
              of the Purchaser's actions or holding of the Mortgage Loans; and

       (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;

provided that, with respect to the representations and warranties in clauses
(iii), (iv), (v) and (vi) above, such representations and warranties cover only
actions taken directly by the Purchaser and its Affiliates or taken by the
Seller at the direction of the Purchaser.

     (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 interests of the Seller, the party discovering such breach shall
give prompt written notice to the other party hereto.

SECTION 4. Repurchases.


                                       6
<PAGE>

     (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 holders of Certificates (any such failure that materially and


                                       7
<PAGE>

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. 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 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 it 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 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 or replace any Mortgage Loan in accordance with Section 4(a) or 4(b)
or disputes its obligation to repurchase or replace 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


                                       8
<PAGE>

provided in this Section 4 shall replace and amend and restate in their entirety
the provisions of Section 4.3 of the Column 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).


                                       9
<PAGE>

     (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, 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. Indemnification.

     (a) The Purchaser (the "Indemnifying Party") agrees to indemnify and hold
harmless the Seller against any and all losses, claims, damages or liabilities,
joint or several, to which it


                                       10
<PAGE>

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
the Purchaser's representations or warranties contained in Section 3(b) of this
Agreement. This indemnity will be in addition to any liability which the
Purchaser may otherwise have.

     (b) The indemnity agreement contained in this Section 8 shall remain
operative and in full force and effect regardless of (i) any termination of this
Agreement, or (ii) any investigation made by any indemnified party.

SECTION 9. 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 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 10. 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 11. 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 12. 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 13. Successors and Assigns.


                                       11
<PAGE>

     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 and its assignee has the right to assign its
interest under this Agreement, in whole or in part. 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.

     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

                                    EXHIBIT A

                             MORTGAGE LOAN SCHEDULE


                                       A-1
<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 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,


                                      B-1
<PAGE>

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. 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).


                                      B-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 twelve 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.


                                      B-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
_________ Mortgage Loans as to which the interest of the related Mortgagor 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.


                                      B-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, permits and authorizations


                                      B-5
<PAGE>

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 each Mortgage Loan which is a
Credit Lease Loan:


                                      B-6
<PAGE>

     (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

          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 either (i) fully amortizes over its original term and has
          no "balloon" payment of rent due under the related Credit Lease or
          (ii) is a Balloon Loan, for which a residual value insurance policy
          has been obtained that requires the payment of an amount at least
          equal to the Balloon Payment due on the related Maturity Date;

     (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;


                                      B-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;

     (I)  For each Credit Lease Loan under which a Credit Lease may be
          terminated upon the occurrence of a casualty or condemnation, a lease
          enhancement insurance policy has been obtained that requires upon such
          termination the payment in full 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, except to the extent of coverage provided by the related
          lease enhancement insurance policy;

     (J)  The terms of any guaranty of the payment and performance obligations
          of the tenant under any Credit Lease are unconditional and provide for
          guaranty of payment and not of collection; and

     (K)  The Borrower under the Mortgage Loan identified as GMACCM Loan No.
          4210 in the Mortgage Loan Schedule (a) does not have any material
          monetary obligations under the Credit Lease other than those for which
          the related tenant is required to reimburse the Borrower and indemnity
          obligations for liabilities imposed by applicable law, (b) does not
          have any material non-monetary obligations under the Credit Lease
          except for the delivery of possession of the leased property and
          providing estoppel certificates, and (c) except for representations
          qualified by its knowledge, has not made any material representation
          or warranty under the Credit Lease that would impose any material
          monetary obligation upon the Borrower or result in the termination of
          the Credit Lease.

     (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


                                      B-8
<PAGE>

"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;

     (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

                                      B-9
<PAGE>

          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 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-10
<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 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 May 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) [Reserved]

         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

<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 GSMC Purchase Agreement.

     The parties hereto agree that, with respect to the Mortgage Loans only, the
GSMC Purchase Agreement is hereby amended to the extent that the provisions of
the GSMC Purchase Agreement are inconsistent with this Agreement.

SECTION 2. Representations, Warranties and Covenants of the Seller.

     (a) The Seller hereby makes, as of June 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.

<PAGE>

       (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 either the ability of the
              Seller to perform its obligations under this Agreement or the
              financial condition of the Seller.

       (vii)  The Seller has not dealt with any broker, investment banker, agent
              or other person, other than the Purchaser, the Underwriters, 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,


                                       3
<PAGE>

              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 by the
Purchaser, to such assignee. The representations, warranties and covenants set
forth in Section 2(a) shall, as between the Seller and the Purchaser,
supplement, and as between the Seller and any successors or assigns of the
Purchaser, replace and amend and restate in their entirety, the representations,
warranties and covenants of the Seller made pursuant to Section 4.1(a) of the
GSMC 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 limited partnership duly organized, validly
              existing and in good standing under the laws of State of New York.

       (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, in each case which materially and adversely
              affect the ability of the Purchaser to carry out the transactions
              contemplated by this Agreement.

       (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


                                       4
<PAGE>

              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 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 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.


                                       5

     (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 the 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)   The Purchaser has full right and authority to sell, assign and
              transfer its interest in such Mortgage Loan;

       (iii)  The Purchaser has not 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 Purchaser's actual knowledge, without independent inquiry
              as to the provisions of the Mortgage Loans, there is no valid
              offset, defense or counterclaim to such Mortgage Loan arising out
              of the Purchaser's actions or holding of the Mortgage Loans; and

       (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;

provided that, with respect to the representations and warranties in clauses
(iii), (iv), (v) and (vi) above, such representations and warranties cover only
actions taken directly by the Purchaser and its Affiliates or taken by the
Seller at the direction of the Purchaser.

     (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 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


                                       7
<PAGE>

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. 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 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 it 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 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 or replace any Mortgage Loan in accordance with Section 4(a) or 4(b)
or disputes its obligation to repurchase or replace 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


                                       8
<PAGE>

provided in this Section 4 shall replace and amend and restate in their entirety
the provisions of Section 4.3 of the GSMC 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).


                                       9
<PAGE>

     (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, 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

     Costs relating to the transactions contemplated hereby and in the Mortgage

SECTION 8. Indemnification.

     (a) The Purchaser (the "Indemnifying Party") agrees to indemnify and hold

joint or several, to which it


                                       10
<PAGE>

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
the Purchaser's representations or warranties contained in Section 3(b) of this
Agreement. This indemnity will be in addition to any liability which the
Purchaser may otherwise have.

     (b) The indemnity agreement contained in this Section 8 shall remain
operative and in full force and effect regardless of (i) any termination of this
Agreement, or (ii) any investigation made by any indemnified party.

SECTION 9. 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 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 10. 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 11. 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

THE NEW YORK GENERAL OBLIGATIONS LAW SHALL APPLY TO THIS AGREEMENT.

SECTION 12. 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

     The rights and obligations of the Seller under this Agreement shall not be

                             MORTGAGE LOAN SCHEDULE



                                       A-1
<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 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,


                                      B-1
<PAGE>

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. 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).


                                      B-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 twelve 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.


                                      B-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
_________ Mortgage Loans as to which the interest of the related Mortgagor 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

     (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

uses).

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


                                      B-5
<PAGE>

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 each Mortgage Loan which is a
Credit Lease Loan:

<PAGE>

     (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

          under the terms of the Credit Lease, (2) none of the terms of the

          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

          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

          no "balloon" payment of rent due under the related Credit Lease or
          (ii) is a Balloon Loan, for which a residual value insurance policy

          equal to the Balloon Payment due on the related Maturity Date;

     (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;

          be modified without the consent of the mortgagees under the related
          Credit Lease Loan;

     (I)  For each Credit Lease Loan under which a Credit Lease may be

          termination the payment in full 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, except to the extent of coverage provided by the related
          lease enhancement insurance policy;

          of the tenant under any Credit Lease are unconditional and provide for

          the related tenant is required to reimburse the Borrower and indemnity
          obligations for liabilities imposed by applicable law, (b) does not

          qualified by its knowledge, has not made any material representation
          or warranty under the Credit Lease that would impose any material
          monetary obligation upon the Borrower or result in the termination of
          the Credit Lease.

     (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


                                      B-8
<PAGE>

"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;

     (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


                                      B-9
<PAGE>

          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 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-10
<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 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

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 May 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.
