          (a) The Company has filed with the Securities and Exchange  Commission
     (the "Commission") a registration statement (No. 333-37717) on Form S-3 for
     the registration  under the Securities Act of 1933, as amended (the "Act"),

     the  Representatives.  The  Company  proposes  to file with the  Commission
     pursuant to Rule 424(b) under the rules and  regulations  of the Commission

     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

     8-K),  together with any amendment thereof or supplement thereto authorized
     by the Company on or prior to the Closing Date for use in  connection  with
     the offering of the Certificates,  are hereinafter  called the "Prospectus"
     and any  diskette  attached to the  Prospectus  is  hereinafter  called the
     "Diskette." Any  preliminary  form of the Prospectus  Supplement  which has
     heretofore  been filed pursuant to Rule 424, or prior to the effective date
     of the  Registration  Statement  pursuant  to Rule  402(a),  or  424(a)  is
     hereinafter called a 

                                       2

<PAGE>


     "Preliminary  Prospectus  Supplement;"  and any  diskette  attached  to the
     Preliminary  Prospectus  Supplement  is  hereinafter  referred  to  as  the
     "Preliminary  Diskette."  As used  herein,  "Pool  Information"  means  the

     the Agreed Upon Procedures  Letter dated May 18, 1998 and rendered by Price
     Waterhouse  LLP (a "hard copy" of which Pool  Information  was initialed on
     behalf of each Mortgage Loan Seller and the Company).

          (b)  The  Registration   Statement  has  become  effective,   and  the
     Registration Statement as of its effective date (the "Effective Date"), and
     the Prospectus,  as of the date of the Prospectus  Supplement,  complied in
     all material  respects with the applicable  requirements of the Act and the
     1933 Act Regulations;  and the Registration  Statement, as of the Effective
     Date,  did not contain any untrue  statement of a material fact and did not
     omit to state any material fact required to be stated  therein or necessary
     to make the  statements  therein not  misleading and the Prospectus and any
     Diskette, as of the date of the Prospectus  Supplement,  did not, and as of
     the Closing Date will not,  contain an untrue  statement of a material fact
     and did not and will not omit to state a material  fact  necessary in order
     to make the statements  therein,  in the light of the  circumstances  under
     which they were made, not misleading;  provided,  however, that neither the
     Company  nor  GMACCM  makes any  representations  or  warranties  as to the
     information contained in or omitted from the Registration  Statement or the
     Prospectus or any amendment  thereof or supplement  thereto relating to the
     information  identified by  underlining or other  highlighting  as shown in
     Exhibit C (the "Excluded Information"); and provided, further, that neither
     the Company nor GMACCM makes any representations or warranties as to either
     (i) any information in any Computational Materials or ABS Term Sheets (each
     as hereinafter  defined) required to be provided by the Underwriters to the
     Company pursuant to Section 4.2, or (ii) as to any information contained in
     or omitted from the portions of the Prospectus identified by underlining or
     other  highlighting as shown in Exhibit D (the "Underwriter  Information");
     and provided, further, that neither the Company nor, except as contemplated
     by Section 1.2(a), GMACCM makes any representations or warranties as to any
     information  regarding  the  Mortgage  Loans or the  Mortgage  Loan Sellers
     contained  in or omitted  from the  portions of the  Prospectus  Supplement
     under the  headings  "Summary of the  Prospectus  Supplement--The  Mortgage
     Asset Pool," "Risk  Factors--The  Mortgage  Loans" and  "Description of the
     Mortgage  Asset  Pool"  or  contained  in or  omitted  from  Annex A to the
     Prospectus  Supplement  or contained  in or omitted from the Diskette  (the
     "Mortgage  Loan Seller  Information"),  other than that any  Mortgage  Loan
     Seller  Information  (exclusive of the  information  set forth on pages A-9
     through A-13, inclusive, of Annex A to the Prospectus Supplement (the "Loan
     Detail") and the information on the Diskette) that represents a restatement
     or aggregation of the information on the Loan Detail,  accurately  reflects
     the information  contained in the Loan Detail; and provided,  further, that
     neither the Company nor GMACCM makes any representations or warranties with
     respect to the Diskette to the extent that the information set forth in the
     Diskette is different  than the  information  set forth in the Loan Detail.
     Neither the Company nor, except as  contemplated by Section 1.2(a),  GMACCM
     makes any  representations  or warranties,  however,  as to the accuracy or
     completeness   of  any   information  in  the  Loan  Detail.   The  Company
     acknowledges that, except for any Computational

     only  information  furnished in writing by or on behalf of any  Underwriter
     for use in connection with the preparation of the  Registration  Statement,
     any preliminary prospectus or the Prospectus,  and the Underwriters confirm
     that the Underwriter Information is correct.

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

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

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

     respects.

          (b) This Agreement has been duly authorized, executed and delivered by
     GMACCM and, assuming the due  authorization,  execution and delivery by the

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

     in authorized denominations of $25,000 or less initial principal balance or
     evidencing percentage interests in such class of less than 20%, as the case
     may be, the fair market value of all such  Certificates  sold to any single
     Person on the date of initial sale thereof by such  Underwriter will not be
     less than $100,000.

          (b) As of the date hereof and as of the Closing Date, such Underwriter
     has complied  with all of its  obligations  hereunder,  including,  without
     limitation,  Section 4.2, and, with respect to all Computational  Materials
     and ABS Term Sheets provided by such Underwriter to the Company pursuant to
     Section 4.2, if any, such  Computational  Materials and ABS Term Sheets are
     accurate in all material  respects  (taking  into  account the  assumptions
     explicitly  set forth in the  Computational  Materials  or ABS Term Sheets,
     except to the extent of any errors therein that are caused by errors in the
     Pool  Information) and include all assumptions  material to the preparation
     thereof.  The Computational  Materials and ABS Term Sheets provided by such
     Underwriter to the Company  constitute a complete set of all  Computational
     Materials and ABS Term Sheets  delivered by such Underwriter to prospective
     investors  that are  required  to be filed  with the  Commission.

     1.4 Each  Representative  represents and warrants to the Company and GMACCM
that it has been  authorized  by each of the other  Underwriters  to execute and
deliver this Agreement on behalf of such Underwriters.

     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 Certificates at a price for each such class
set forth in Schedule I hereto.  There will be added to the  purchase  prices of
the  Certificates  an amount equal to interest  accrued thereon from the Cut-off
Date to but not including the Closing Date.

     3. Delivery and Payment. Delivery of and payment for the Certificates shall
be made at the office of Orrick,  Herrington & Sutcliffe LLP at 10:00 a.m.,  New
York City time, on May 18, 1998 or such later date as the Representatives  shall
designate,  which  date and time  may be  postponed  by  agreement  between  the
Representatives  and the Company (such date and time of delivery and payment for
the  Certificates  being  herein  called the  "Closing  Date").  Delivery of the
Certificates  (also  referred  to herein as the "DTC  Registered  Certificates")
shall  be  made  to the  Representatives  for  the  respective  accounts  of the
Underwriters through DTC, in each case against payment by the Underwriters to or
upon the order of each  Mortgage  Loan Seller by wire  transfer  in  immediately
available  funds of the amount to which such Mortgage Loan Seller is entitled in
accordance with the terms of an allocation  agreement dated the date hereof (the
"Allocation  Agreement"),  to which  each  such  Mortgage  Loan  Seller  and the
Company,  among others,  are parties.  As a further condition to the delivery of
the

                                       5

DTC  Registered  Certificates,  each  Representative  shall  have  furnished  by
telephonic  notice to the applicable  Mortgage Loan Seller the federal reference
number for the related wire transfer to such Mortgage Loan Seller and shall have
furnished  to the  Company  each  such  federal  reference  number  as  soon  as
practicable after such federal reference number becomes available.

     4. Offering by Underwriters.

     4.1  It  is  understood  that  the   Underwriters   propose  to  offer  the
Certificates  for sale to the  public  as set forth in the  Prospectus,  and the
Underwriters  agree that all such offers and sales by the Underwriters  shall be
made in  compliance  with all  applicable  laws and  regulations.  It is further
understood  that the  Company,  in  reliance  upon a  no-filing  letter from the
Attorney  General of the State of New York granted  pursuant to Policy Statement
105, has not and will not file an offering  statement  pursuant to Section 352-e
of the  General  Business  Law of the  State of New  York  with  respect  to the
Certificates.  As required by Policy Statement 105, each  Underwriter  therefore
covenants  and agrees with the Company  that sales of the  Certificates  made by
such  Underwriter  in and  from  the  State  of New  York  will be made  only to
institutional investors within the meaning of Policy Statement 105.

     4.2 It is  understood  that each  Underwriter  may  prepare  and provide to
prospective investors certain Computational  Materials and ABS Term Sheets (each
as defined below) in connection with its offering of the  Certificates,  subject

     statement:

          "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  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

                                       7

<PAGE>


     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  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 

                                       8

<PAGE>


     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.

          (i) 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 Certificates, (a) if less than 10% of the aggregate actual
or notional, as the case may be, principal balance of such class of 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
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 Certificates, then the weighted average price
at which the  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 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  Certificates  was  sold  to the  public,  (ii)  the  prepayment
assumption  used in  pricing  each class of  Certificates,  and (iii) such other
information  as to  matters of fact as the  Company  may  

                                       9

<PAGE>


reasonably  request to enable it to comply with its reporting  requirements with
respect to each class of 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  Certificates,  the  Company  will  furnish the
Representatives with a copy of each such proposed amendment or supplement.

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

     5.3 If,  during the period  after the first date of the public  offering of
the Certificates in which a prospectus  relating to the 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  Representatives  on behalf of the several
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 Representatives, 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  Representatives  may
reasonably request. 

     5.5 The Company agrees,  so long as the 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
Representatives  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
Certificates   for  sale   under   the  laws  of  such   jurisdictions   as  the
Representatives may reasonably designate and will maintain such qualification in
effect so long as required  for the initial  distribution  of the  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.

                                       10

     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  Certificates.  

     5.8 If,  during the period  after the  Closing  Date in which a  prospectus
relating to the  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  Certificates is
in effect,  the Company will advise the  Representatives 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 Price  Waterhouse LLP,  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  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  December  31,  1997,  there shall have been no material  adverse
change (not in the ordinary  course of business) in the condition of the Company
or  GMACCM.  

     6.3 The Company shall have  delivered to the  Underwriters  a  certificate,
dated the Closing  Date,  of the  President,  a Senior Vice  President or a Vice
President of the Company to the effect that the signer of such  certificate  has
examined this Agreement, the 

                                       11

          (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.

     6.4 GMACCM shall have delivered to the  Underwriters  a certificate,  dated

Date and  substantially  to the effect set forth in Exhibit A and 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.

     6.6 The  Underwriters  shall have received from Brown & Wood, LLP,  counsel
for the  Underwriters,  an opinion  dated the Closing Date in form and substance
reasonably  satisfactory to the  Underwriters. 

     6.7 The  Underwriters  shall  have  received  from  Price  Waterhouse  LLP,
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 Pool,"
"Description of the Certificates" and "Yield and Maturity Considerations" agrees
with the records of the Company and the  Mortgage  Loan  Sellers  excluding  any
questions  of legal  interpretation  and (b) the  letter  prepared  pursuant  to
Section 5.9 hereof.  

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

     6.9 The Underwriters  shall have received,  with respect to the Trustee,  a

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

     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 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 GMACCM 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 of
Prospectus  Supplement - The Mortgage  Asset

                                       13

Pool," "Risk Factors - The Mortgage  Loans" and/or  "Description of the Mortgage
Asset Pool" or on Annex A to the  Prospectus  Supplement  (exclusive of the Loan
Detail)  and  such  information  represents  a  restatement  or  aggregation  of
information  contained in the Loan Detail, or (iii) any such untrue statement or
alleged  untrue  statement  or omission or alleged  omission is with  respect to
information  regarding  GMACCM or the GMACCM  Mortgage  Loans  contained  in the
Prospectus Supplement under the headings "Summary of Prospectus Supplement - The
Mortgage Asset Pool," "Risk Factors - The Mortgage Loans" and/or "Description of
the Mortgage Asset Pool" or on Annex A to the Prospectus  Supplement  (exclusive
of the Loan Detail),  and such  information  does not represent a restatement or
aggregation 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,  except 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  portion  of the Pool
Information relating to the GMACCM Mortgage Loans.

     7.2 Each  Underwriter  agrees,  severally  and not jointly to indemnify and
hold harmless the Company,  GMACCM,  their respective  directors or officers and
any person who  controls  the  Company  or GMACCM  within the  meaning of either
Section 15 of the Act or Section 20 of the  Exchange  Act to the same  extent as
the  indemnity  set forth in clause 7.1 above from the Company and GMACCM to the
Underwriters,  but only with respect to (i) the Underwriter Information relating
to such Underwriter or supplied by such Underwriter to the Company for inclusion
in the Prospectus  Supplement and (ii) the Computational  Materials and ABS Term
Sheets delivered to investors in the Certificates by such Underwriter, except to
the extent of any errors in the Computational  Materials or ABS Term Sheets that
are  caused by errors in the Pool  Information.  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  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
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 

                                       14

<PAGE>


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  Representatives,  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 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.

     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  

                                       15

<PAGE>


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 Certificates.

     8.  Termination.  This Agreement  shall be subject to termination by notice
given to the Company and GMACCM,  if the sale of the  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 Certificates.

     9. Default by an Underwriter. If any Underwriter shall fail to purchase and
pay for any of the  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  Certificates  that the defaulting
Underwriter agreed but failed to purchase;  provided, however, that in the event
that  the  initial   principal  amount  of  Certificates   that  the  defaulting
Underwriter  agreed but failed to  purchase  shall  exceed 10% of the  aggregate
principal balance of all of the 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  Certificates,  and  if  such
nondefaulting  Underwriters  do  not  purchase  all of  the  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 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.

Company,  GMACCM, the Underwriters or the officers of any of the Company, GMACCM

To:   Persons Listed on Annex A hereto

               GMAC Commercial Mortgage Securities, Inc.,
               Mortgage Pass-Through Certificates, Series 1998-C1


Ladies and Gentlemen:


     I am General  Counsel to GMAC  Commercial  Mortgage  Securities,  Inc. (the
"Company")  and  GMAC  Commercial  Mortgage  Corporation  ("GMACCM").   In  that
capacity,  I am  familiar  with the  issuance of certain  Mortgage  Pass-Through
Certificates,   Series  1998-C1  (the   "Certificates"),   evidencing  undivided
interests  in a trust fund (the "Trust  Fund")  consisting  primarily of certain
mortgage  loans (the  "Mortgage  Loans"),  pursuant to a Pooling  and  Servicing
Agreement,  dated as of May 1, 1998 (the  "Pooling  and  Servicing  Agreement"),
among the Company as depositor,  GMACCM as master servicer and special servicer,
LaSalle  National  Bank as trustee  (the  "Trustee")  and ABN AMRO Bank N.V.  as
fiscal agent.

     Certain of the Mortgage Loans (the "GMACCM  Mortgage Loans") were purchased
by the Company from GMACCM pursuant to, and for the consideration  described in,
the Mortgage  Loan Purchase  Agreement,  dated as of April 28, 1998 the ("GMACCM
Mortgage Loan Purchase Agreement"),  between GMACCM and the Company.  Certain of
the Mortgage  Loans (the "GACC  Mortgage  Loans") were  purchased by the Company
from German American Capital Corporation  ("GACC") pursuant to the Mortgage Loan
Purchase Agreement, dated as of April 28, 1998 (the "GACC Mortgage Loan Purchase
Agreement"), between GACC and the Company.

     The Company sold the Class X, Class A-1, Class A-2, Class B, Class C, Class
D,  Class E and  Class  F  Certificates  (collectively,  the  "Publicly  Offered
Certificates")  to Deutsche  Morgan  Grenfell  Inc. and Lehman  Brothers Inc. as
representatives   (the   "Representatives")   for   themselves   and  the  other
underwriters (the "Underwriters") named in the Underwriting Agreement,  dated as
of April 28, 1998 (the "Underwriting Agreement"),  among the Company, GMACCM and
the  Representatives,  and sold the Class G, Class H, Class J, Class K, Class L,
Class M, Class N, Class R-I,  Class R-II and R-III  Certificates  (collectively,
the  "Privately  Offered  Certificates")  to Deutsche  Morgan  Grenfell Inc. and
Lehman Brothers Inc. as initial purchasers (the "Initial  Purchasers")  pursuant
to  the  Certificate  Purchase  Agreement,  dated  as of  April  28,  1998  (the
"Certificate  Purchase  Agreement"),  among the Company,  GMACCM and the Initial
Purchasers (the Certificate Purchase Agreement,  the Underwriting Agreement, the
GMACCM  Mortgage  Loan  Purchase  Agreement,  the GACC  Mortgage  Loan  Purchase
Agreement  and  the  Pooling  and   Servicing   Agreement,   collectively,   the
"Agreements"). Capitalized terms not defined herein have

                                      B-1

<PAGE>


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.

     2. 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,  and to enter into and  perform  its
obligations under the Agreements.

     3. 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 

                                      B-2

<PAGE>


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,  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.

     4. 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.

     5. 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,  State of  California  or federal  statute or
regulation or conflict with, result in a breach, violation or acceleration of or
constitute  a  default  under  the  terms of any  indenture  or  other  material
agreement or instrument to which GMACCM or the Company is a party or by which it
is bound or any order or  regulation  of any  Commonwealth  of  Pennsylvania  or
federal court,  regulatory  body,  administrative  agency or  governmental  body
having jurisdiction over GMACCM or the Company.

     This  opinion  letter is rendered  for the sole  benefit of each  addressee
hereof,  and no other person or entity,  except  Orrick,  Herrington & Sutcliffe
LLP, is entitled to rely hereon without my prior written consent. Copies of this
opinion  letter may not be furnished to any other person or entity,  nor may any
portion of this opinion letter be quoted, circulated or referred to in any other
document without my prior written consent.


                                            Very truly yours,

                                            Maria Corpora-Buck

     Re:  GMAC Commercial Mortgage Securities, Inc., Mortgage
          Pass-Through Certificates, Series 1998-C1


     Pursuant to Section 4.3 of the Underwriting Agreement, dated April 28, 1998
(the "Underwriting Agreement"), among GMAC Commercial Mortgage Securities, Inc.,
GMAC  Commercial  Mortgage  Corporation  and,  Deutsche Morgan Grenfell Inc. and
Lehman  Brothers  Inc.,  each as  representative  on behalf  of  itself  and the
underwriters set forth therein (the "Underwriters") relating to the Certificates
referenced above, 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
18, 1998; (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:

     This Pooling and Servicing Agreement (this "Agreement"), is dated and
effective as of May 1, 1998, among GMAC COMMERCIAL MORTGAGE SECURITIES, INC., as
Depositor, GMAC COMMERCIAL MORTGAGE CORPORATION, as Master Servicer, GMAC
COMMERCIAL MORTGAGE CORPORATION, as Special Servicer, LASALLE NATIONAL BANK, 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 Stated
Principal Balances of the Mortgage Loans is approximately $1,438,000,264.

     As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of the Mortgage Loans 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.

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

     SECTION 2.01 Establishment of Trust; Conveyance of Mortgage Loans.

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

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



                                       56
<PAGE>

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(c).  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.
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  



                                       57
<PAGE>

the Trustee  shall upon receipt  thereof  cause the same to be duly  recorded or
filed, as appropriate.

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

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

     SECTION 2.02 Acceptance by Trustee.

     (a)  The  Trustee,  by  the  execution  and  delivery  of  this  Agreement,

delivered  to it, in good faith and  without  notice of any adverse  claim,  and
declares that it or a Custodian on its behalf holds and will hold such documents
and the other documents delivered or caused to be delivered by the Mortgage Loan
Sellers  constituting  the Mortgage Files,  and that it holds and will hold such
other assets  included in REMIC I, in trust for the exclusive use and benefit of
all present and future Certificateholders.

     (b) Within 60 days of the Closing  Date,  the Trustee or a Custodian on its
behalf shall review each of the Mortgage Loan  documents  delivered or caused to
be delivered by the Mortgage Loan Sellers  constituting the Mortgage Files; and,
promptly  following such review, the Trustee shall certify in writing to each of
the Depositor,  the Master Servicer, the Special Servicer and each Mortgage Loan
Seller  that,  as to each  Mortgage  Loan listed in the Mortgage  Loan  Schedule
(other than any  Mortgage  Loan paid in full or any Mortgage  Loan  specifically
identified in any exception  report annexed thereto as not being covered by such
certification),  (i) all  documents  specified in clauses (1), (2), (3), (9) and
(12) of the  definition of "Mortgage  File" are in its possession or the related
Mortgage  Loan Seller has  otherwise  satisfied  the  delivery  requirements  in
accordance with Section  2.01(b),  (ii) all documents  delivered or caused to be
delivered by the related Mortgage Loan Seller  constituting the related

forth in the  Mortgage  Loan  Schedule  with  respect to the items  specified in
clauses (i),  (ii),  (iii),  (iv) and (vii) of the  definition of "Mortgage Loan
Schedule", is correct.

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

any duty or obligation (i) to determine  whether any of the documents  specified
in clauses (4) - (8), (10),  (11),  (13) and (14) of the definition of "Mortgage
File" exist or are required to be delivered by the Depositor,  any Mortgage Loan
Seller or any other  Person or (ii) to  inspect,  review or  examine  any of the
documents,  instruments,  certificates  or other papers relating to the Mortgage
Loans  delivered to it to determine that the same are genuine,  enforceable,  in
recordable  form or  appropriate  for the  represented  purpose or that they are
other than what they purport to be on their face.

     (e) If, in the  process  of  reviewing  the  Mortgage  Files or at any time
thereafter,  the Trustee or any Custodian  finds (or, if at any time,  any other
party hereto finds) any document or documents  constituting a part of a Mortgage
File to have not been properly executed or, subject to Section 2.01(b),  to have
not been delivered, to contain information that does not conform in any material
respect  with the  corresponding  information  set  forth in the  Mortgage  Loan
Schedule,  or to be  defective  on its face  (each,  a "Defect"  in the  related

                                       59
<PAGE>


Mortgage Loan  Schedule,  the Depositor  shall  promptly  correct such error and
distribute a new,  corrected Mortgage Loan Schedule to each of the other parties
hereto,  and upon  receipt by the  Trustee  of such a  corrected  Mortgage  Loan
Schedule so  identified,  such new,  corrected  Mortgage Loan Schedule  shall be
deemed  to amend  and  replace  the  existing  Mortgage  Loan  Schedule  for all
purposes.

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

     (a) If the Trustee discovers or receives notice of a Defect in any Mortgage
File or a breach of any  representation or warranty set forth in Section 4(a) of
each Mortgage Loan Purchase  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,
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 shall request that
the related  Mortgage  Loan Seller,  within the time period  provided for in the
related Mortgage Loan Purchase Agreement,  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,  provided,  however, that in lieu of effecting any such
repurchase,  a Mortgage  Loan 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
related Mortgage Loan Purchase Agreement and this Agreement;  provided, further,
that if such Breach would cause the Mortgage  Loan to be other than a "qualified
mortgage"  under  Section  860G(a)(3)  of the Code,  such Breach  shall be cured
within 90 days of discovery.

     As to any Qualifying  Substitute  Mortgage Loan or Loans, the Trustee shall
direct the  related  Mortgage  Loan  Seller 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 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  shall be entitled to retain all
amounts received in respect of such Deleted Mortgage Loan.


                                       60
<PAGE>


     In any month in which the related  Mortgage Loan Seller  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 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 to give  written  notice to the  Trustee  and the  Master
Servicer of such  deposit,  accompanied  by an Officers'  Certificate  as to the
calculation  the applicable  Substitution  Shortfall  Amount.  The Trustee shall
direct the related  Mortgage  Loan Seller 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,

Account as the account to which funds in the amount of the Purchase Price are to

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

     SECTION 3.01 Servicing and Administration of the Mortgage Loans.

     (a) Each of the Master Servicer and the Special  Servicer shall service and
administer  the Mortgage  Loans that it is  obligated to service and  administer
pursuant to this Agreement on behalf of the Trustee and in the best interests of
and for the  benefit  of the  Certificateholders  (as  determined  by the Master
Servicer  or the  Special  Servicer,  as the case may be, in its good  faith and
reasonable  judgment),  in  accordance  with  applicable  law, the terms of this
Agreement  and the terms of the  respective  Mortgage  Loans and,  to the extent
consistent with the foregoing, further as follows: (i) with the same care, skill
and diligence as is normal and usual in its general  mortgage  servicing and REO
property  management  activities  on  behalf  of third  parties  or on behalf of
itself,  whichever is higher,  with respect to mortgage loans and REO properties
that are comparable to those for which it is responsible hereunder;  (ii) with a
view to the  timely  collection  of all  scheduled  payments  of  principal  and
interest  under the  Mortgage  Loans  or,  if a  Mortgage  Loan  comes  into and
continues  in default and if, in the good faith and  reasonable  judgment of the
Special Servicer, no satisfactory arrangements can be made for the collection of
the delinquent payments,  the maximization of the recovery on such Mortgage Loan
to the  Certificateholders (as a collective whole) on a present value basis (the
relevant  discounting of anticipated  collections  that will be distributable to
Certificateholders  to be performed at the related Net Mortgage Rate); and (iii)
without regard to (A) any  relationship  that the Master Servicer or the Special
Servicer, as the case may be, or any Affiliate thereof may have with the related
Mortgagor,  (B) the ownership of any  Certificate by the Master  Servicer or the
Special  Servicer,  as the case may be,  or by any  Affiliate  thereof,  (C) the
Master  Servicer's  obligation  to make  Advances,  (D) the  Special  Servicer's
obligation to make (or to direct the Master Servicer to make) Servicing Advances
and (E) the right of the  Master  Servicer  (or any  Affiliate  thereof)  or the
Special  Servicer  (or any  Affiliate  thereof),  as the case may be, to receive
reimbursement  of costs, or the sufficiency of any  compensation  payable to it,
hereunder or with respect to any  particular  transaction  (the  conditions  set
forth in the immediately  foregoing  clauses (i), (ii) and (iii), the "Servicing
Standard"). Without limiting the generality of the foregoing, each of the Master
Servicer  and the Special  Servicer,  in its own name,  in  connection  with its
servicing and administrative duties hereunder is hereby authorized and empowered
by the Trustee to exercise efforts consistent with the foregoing standard and to
execute and deliver, on behalf of the  Certificateholders and the Trustee or any
of them,  any and all financing  statements,  continuation  statements and other
documents or instruments  necessary to maintain the lien created by any Mortgage
or other security document in the related Mortgage File on the related Mortgaged
Property  and  related  collateral;   subject  to  Section  3.20,  any  and  all
modifications,  waivers,  amendments  or  consents  to or  with  respect  to any
documents contained in the related Mortgage File; and any and all instruments of
satisfaction  or  cancellation,  or of full release or 



                                       64
<PAGE>


discharge,  and all other comparable  instruments,  with respect to the Mortgage
Loans and the Mortgaged Properties.  Each of the Master Servicer and the Special
Servicer is also authorized to approve a request by a Mortgagor under a Mortgage
Loan that it is obligated to service and administer  pursuant to this Agreement,
for an easement,  consent to  alteration  or  demolition,  and for other similar
matters,  provided that the Master Servicer or the Special Servicer, as the case
may  be,  determines,  exercising  its  good  faith  business  judgment  and  in
accordance with the Servicing  Standard,  that such approval will not affect the
security  for, or the timely and full  collectability  of, the related  Mortgage
Loan.  Subject  to Section  3.10,  the  Trustee  shall  furnish,  or cause to be
furnished,  to the  Master  Servicer  and the  Special  Servicer  any  powers of
attorney  and other  documents  necessary  or  appropriate  to enable the Master
Servicer or the Special Servicer, as the case may be, to carry out its servicing
and administrative duties hereunder;  provided,  however, that the Trustee shall
not be held  liable,  and shall be  indemnified  by the Master  Servicer  or the
Special Servicer,  as applicable,  for any negligence with respect to, or misuse
of, any such power of attorney by the Master  Servicer or the Special  Servicer,
as the case may be.

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

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

     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.

     (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 


                                       66
<PAGE>


of effecting the payment of (i) real estate taxes, assessments and other similar
items that are or may become a lien thereon,  (ii) ground rents (if applicable),
and (iii) premiums on Insurance Policies,  in each instance if and to the extent
Escrow  Payments  collected from the related  Mortgagor are  insufficient to pay
such item when due and the  related  Mortgagor  has failed to pay such item on a
timely  basis,  and provided  that the  particular  advance  would not, if made,
constitute  a  Nonrecoverable  Servicing  Advance.  All such  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.

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

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

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

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


                                       67
<PAGE>


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

     (iv) all Insurance Proceeds and Liquidation Proceeds received in respect of
any Mortgage  Loan or REO Property  (other than  Liquidation  Proceeds  that are
received in connection with the Master Servicer's or 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

     (vi) 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.

     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  



                                       68
<PAGE>


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)(vi), (b)(iii) 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) [reserved];

     (ii) 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);

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


                                       69

     (iv) 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

     (v) 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  (ii)  through  (v) 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
(ii) through (v),  then the Trustee  shall  provide  notice of such failure to a
Servicing  Officer of the Master  Servicer  by  facsimile  transmission  sent to

Servicer to the Trustee in writing)  and by  telephone  at  telephone  no. (215)
328-1789  (or such  alternative  number  provided by the Master  Servicer to the
Trustee in writing) as soon as possible,  but in any event before 5:00 p.m., New
York City time, on such day.

     Funds in the Distribution Account shall not be invested.  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

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

withdraw  from the  Distribution  Account  and deposit in the  Interest  Reserve
Account an amount equal to the aggregate of the Withheld  Amounts  calculated in
accordance  with the  previous  sentence.  If the Trustee  shall  deposit in the
Interest Reserve Account any amount not required to be deposited therein, it may
at any  time  withdraw  such  amount  from the  Interest  Reserve  Account,  any
provision  herein to the  contrary  notwithstanding.  On or prior to the  Master
Servicer  Remittance  Date in March of each  calendar

any withdrawal from the Certificate Account.

     The Master  Servicer  shall pay to the Special  Servicer (or to third party

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



                                       74

     (a)  (i)  The  Master  Servicer  may  direct  any  depository   institution
maintaining the Certificate  Account,  any Lock-Box Account, any Cash Collateral
Account or the  Interest  Reserve  Account,  and (ii) the Special  Servicer  may
direct  any  depository  institution  maintaining  the REO  Account  (each,  for
purposes of this Section 3.06, an "Investment 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 Investment of amounts in the Interest Reserve
Account),  shall maintain continuous possession of any Permitted Investment that
is either (i) a "certificated  security", as such term is defined in the Uniform
Commercial  Code of any  applicable  jurisdiction  (the  "UCC"),  or (ii)  other
property  in  which a  secured  party  may  perfect  its  security  interest  by
possession  under the UCC or any other  applicable  law.  Possession of any such
Permitted  Investment  by the  Master  Servicer,  or the  Special  Servicer,  as
applicable,  shall constitute  possession by a person  designated by the Trustee
for purposes of Articles 8 and 9 of the UCC and  possession  by the Trustee,  as
secured party, for purposes of Section 9-305 of the UCC and any other applicable
law. In the event  amounts on deposit in an  Investment  Account are at any time
invested in a Permitted  Investment  payable on demand,  the Master Servicer (in
the case of the Certificate Account, any Lock-Box Account or any Cash Collateral
Account),  the Special Servicer (in the case of the REO Account) and the Trustee
(in the case of the 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 or the Interest  Reserve Account and, to the extent the
Master Servicer  directs the investment of funds in any Lock-Box  Account or any
Cash  Collateral  Account,  



                                       75
<PAGE>

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) or 3.05(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 or the Interest
Reserve Account, and to the extent the Master Servicer directs the investment of
funds in any Lock-Box Account or any Cash Collateral Account 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 REO Account,  the Special Servicer shall promptly deposit therein
from its own funds, without right of reimbursement, no later than the end of the
Collection  Period  during which such loss was  incurred,  the amount of the Net
Investment Loss, if any, for such Collection Period.

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

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

     (a) Each of the Master  Servicer (in the case of Mortgage  Loans other than
Specially  Serviced  Mortgage  Loans) and the Special  Servicer  (in the case of
Specially  Serviced  Mortgage Loans) shall use reasonable  efforts to cause each
Mortgagor to maintain in respect of the related Mortgaged Property all insurance
coverage  as is  required  under  the  related  Mortgage;  provided  that if any
Mortgage  permits the holder  thereof to dictate to the  Mortgagor the insurance
coverage to be maintained on such Mortgaged Property, the Master Servicer or the
Special Servicer,  as appropriate,  shall impose such insurance  requirements as
are consistent  with the Servicing  Standard.  If a Mortgagor  fails to maintain
such insurance, the Master Servicer (at the direction of the Special Servicer in
the case of a  Specially  Serviced  Loan)  shall  (to the  extent  available  at
commercially  reasonable  terms) obtain such  insurance  (which may be through a
master  or  single  interest  policy)  and the cost  (including  any  deductible
relating to such  insurance)  of such  insurance  (or in the case of a master or
single interest policy, the incremental cost (including any deductible  relating
to  such  insurance)  of  such  insurance  relating  to the  



                                       76

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


                                       77

     (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  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  



                                       78
<PAGE>


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.  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)  not less than (i) Baa2 by Moody's and (ii) 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 (i)
and (ii) shall not be  applicable  with  respect to  Moody'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)(iii),  waive its right to exercise) any
right it may have with  respect  to such  Mortgage  Loan (x) to  accelerate  the
payments  thereon,  or (y) to  withhold  its  consent  to 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




                                       79
<PAGE>


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. 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
with respect to a Mortgage Loan having one of the then-ten  highest  outstanding
principal  balances in the  Mortgage  Pool,  the Master  Servicer or the Special
Servicer,  as the case may be,  prior to  entering  into such  agreement,  shall
submit  to  FITCH  IBCA a copy  of  such  agreement  together  with  such  other
information  with  respect  to such  action as the  Master  Servicer  or Special
Servicer,  as  applicable,  deems  appropriate  or as FITCH IBCA may  reasonably
request,  and shall  request that FITCH IBCA  deliver to the Master  Servicer or
Special Servicer, as applicable, written confirmation that the execution of such
agreement  would not result in a  qualification,  withdrawal or downgrade of the
then-current  ratings of the  Certificates.  FITCH  IBCA  shall  respond to such
request within five (5) Business Days of receipt of a copy of such agreement and
any information FITCH IBCA so reasonably  requests;  provided,  however,  if the
Master  Servicer  or  Special  Servicer  shall not have  received  such  written
confirmation  within five (5) Business Days of FITCH IBCA's receipt of a copy of
such  agreement  and  such  information,  such  written  confirmation  shall  be
considered to have been delivered to the Master Servicer or Special  Servicer by
FITCH IBCA.

     (b) As to each Mortgage Loan which  contains a provision in the nature of a
"due-on-encumbrance" clause, which by its terms:

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

     (ii)  requires  the consent of the  mortgagee  to the  creation of any such
additional lien or other  encumbrance on the related Mortgaged  Property,  then,
for so long as such  Mortgage  Loan is included  in the Trust  Fund,  the Master
Servicer  or, in the case of a Specially  Serviced  Mortgage  Loan,  the Special
Servicer,  on behalf of the Trustee as the mortgagee of record,  shall  exercise
(or, subject to Section 3.20(a)(iii),  waive its right to exercise) any right it
may have with  respect to such  Mortgage  Loan (x) to  accelerate  the  payments
thereon,  or (y) 



                                       80
<PAGE>


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 Special  Servicer (as applicable)  with
respect to any Mortgage  Loan or Specially  Serviced  Mortgage Loan which has an
unpaid  principal  balance  at  such  time  equal  to at  least  5% of the  then
outstanding balance of the Mortgage Pool, has received written confirmation from
each Rating  Agency that such  waiver,  in and of itself,  would not result in a
downgrade,  qualification  or withdrawal of the then current ratings assigned to
any class of Certificates.

     (c) With respect to any Mortgage  Loan which  permits  release of Mortgaged
Properties through a Defeasance Option, the Master Servicer shall, to the extent
consistent with and permitted by the applicable Mortgage Loan documents,  permit
the exercise of such  Defeasance  Option on any Due Date occurring more than two
years after the Startup Day (the "Release  Date") upon the  satisfaction  of 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;


                                       81
<PAGE>


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

     (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.

     (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  



                                       82
<PAGE>


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 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  



                                       83
<PAGE>


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  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

     (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 



                                       84
<PAGE>


clauses (i) and (ii) of the first sentence  thereof has not been  satisfied,  in
each case until the earliest to occur of satisfaction  of both such  conditions,
removal of the related Mortgage Loan from the Trust Fund and release of the lien
of the related Mortgage on such Mortgaged Property.

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

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


                                       85
<PAGE>


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

     (c) Within three  Business Days (or within such shorter  period as delivery
can reasonably be accomplished if the Special  Servicer  notifies the Trustee of
an exigency) of receipt  thereof,  the Trustee  shall execute and deliver to the
Special  Servicer  any court  pleadings,  requests for  trustee's  sale or other
documents  necessary  to the  foreclosure  or  trustee's  sale in  respect  of a
Mortgaged Property or to any legal action brought to obtain judgment against any
Mortgagor on the Mortgage  Note or Mortgage or to obtain a deficiency  judgment,
or to enforce any other  remedies or rights  provided  by the  Mortgage  Note or
Mortgage or otherwise  available at law or in equity. The Special Servicer shall
be responsible  for the  preparation  of all such documents and pleadings.  When
submitted to the Trustee for  signature,  such  documents or pleadings  shall be
accompanied by a certificate of a Servicing Officer  requesting that such plead-
ings 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 Master  Servicing  Fee with respect to each  Mortgage
Loan and REO Loan. As to each Mortgage Loan and REO Loan,  the Master  Servicing
Fee shall accrue from time to time at the Master Servicing Fee Rate and shall be
computed  on the  basis of the same  principal  amount  and for the same  period
respecting  which any  related  interest  payment due on such  Mortgage  Loan or
deemed to be due on such REO Loan is  computed.  The Master  Servicing  Fee with
respect to any Mortgage  Loan or REO Loan shall cease to accrue if a Liquidation
Event  occurs in  respect  thereof.  The Master  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 Master Servicing Fees in respect of
any Mortgage Loan or REO Loan out of that portion of related Insurance  



                                       86
<PAGE>


Proceeds or  Liquidation  Proceeds  allocable as recoveries of interest,  to the
extent permitted by Section  3.05(a).  The right to receive the Master 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 collected on the Mortgage
Loans;  (ii)  interest or other  income  earned on  deposits in the  Certificate
Account and the Interest  Reserve  Account,  in accordance  with Section 3.06(b)
(but only to the extent of the Net Investment Earnings,  if any, with respect to
each such  Investment  Account  for each  Collection  Period),  and (iii) to the
extent not required to be paid to any Mortgagor  under  applicable  law or under
the related  Mortgage,  any interest or other  income  earned on deposits in the
Servicing Accounts and Reserve Accounts maintained thereby.  The Master Servicer
shall be  required  to pay out of its own funds all  overhead  and  general  and
administrative  expenses  incurred  by  it  in  connection  with  its  servicing
activities hereunder (including,  without limitation, payment of any amounts due
and  owing  to any of  Sub-Servicers  retained  by it and the  premiums  for any
blanket policy insuring against hazard losses pursuant to Section  3.07(b)),  if
and to the extent such expenses are not payable  directly out of the Certificate
Account, and the Master Servicer shall not be entitled to reimbursement therefor
except as expressly  provided in this  Agreement.  The Master Servicer shall pay
the Trustee Fee out of the Servicing Fee without right of reimbursement.

     (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 basis of the same
principal  amount and for the same period  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 Section 9.01).  As to each such  Specially  Serviced
Mortgage Loan or REO Property,  the  Liquidation  Fee shall be payable from, and
shall be calculated by application of the  Liquidation Fee Rate to, such full or
discounted payoff and/or such Liquidation  Proceeds.  No Liquidation Fee will be
payable with respect to any Specially Serviced Mortgage Loan solely by virtue of
such Mortgage Loan becoming a Corrected Mortgage Loan.  Notwithstanding anything
herein to the contrary,  no Liquidation  Fee will be payable from, or based upon
the receipt of, Liquidation  Proceeds collected as a result of any purchase of a
Specially  Serviced Mortgage Loan or REO Property described in the parenthetical
to the first sentence of this  paragraph;  provided,  however,  that if any such
Liquidation  Proceeds are received with respect to any Corrected Mortgaged Loan,
and the Special Servicer is properly  entitled to a Workout Fee therefrom,  such
Workout Fee will be payable  based on and from the  portion of such  Liquidation
Proceeds that constitute principal and/or interest.

     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 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 3.11(g)  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, 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




                                       89
<PAGE>


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).  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 within 60 days of its preparation.


                                       90
<PAGE>


     (b) The  Special  Servicer  shall  perform  (or  cause to be  performed)  a
physical  inspection of each Mortgaged  Property  constituting  collateral for a
Specially  Serviced  Mortgage  Loan at such  times  and in  such  manner  as are
consistent with the Servicing Standard. If any Mortgage Loan becomes a Specially
Serviced  Mortgage Loan, then as soon as practicable (and in any event within 90
days thereafter) the Special Servicer shall perform (or cause to be performed) a
physical inspection of each Mortgaged Property constituting  collateral for such
Mortgage  Loan.  The Special  Servicer shall prepare (or cause to be prepared) a
written report of each such inspection  detailing the condition of the Mortgaged
Property  and  specifying  the  existence  of (i) any  vacancy in the  Mortgaged
Property  evident from such inspection that the Special Servicer deems material,
(ii) any sale,  transfer or abandonment of the Mortgaged  Property  evident from
such  inspection,  (iii) any  adverse  change in the  condition  or value of the
Mortgaged  Property evident from such inspection that the Special Servicer deems
material,  or (iv) any waste  committed on the Mortgaged  Property  evident from
such  inspection.  The Special  Servicer,  upon  request,  shall  deliver to the
Trustee and the Master  Servicer a copy of each such  written  report  within 60
days of its preparation.

     (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 quarterly and annual operating  statements and rent rolls of
the related Mortgaged Property,  and financial statements of such Mortgagor,  if
delivery  of such  items  is  required  pursuant  to the  terms  of the  related
Mortgage.  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 1999, 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  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 1999,  the  Master
Servicer at its expense  shall cause a firm of  independent  public  accountants
(which may also  render  other  services to the Master  Servicer)  and that is a
member of the American  Institute of Certified  Public  Accountants to furnish a
statement  to the  Trustee  and to the  Depositor  to the effect that (i) it has
obtained  a  letter  of  representation   regarding  certain  matters  from  the
management of the Master  Servicer,  which includes an assertion that the Master
Servicer has complied with certain minimum mortgage loan servicing standards (to
the extent applicable to commercial and multifamily mortgage loans),  identified
in the Uniform Single  Attestation  Program for Mortgage Bankers  established by
the Mortgage  Bankers  Association of America,  with respect to the servicing of
commercial and  multifamily  mortgage  loans during the most recently  completed
calendar year and (ii) on the basis of an examination  conducted by such firm in
accordance  with standards  established  by the American  Institute of Certified
Public  Accountants,  such  representation  is  fairly  stated  in all  material
respects,  subject  to such  exceptions  and  other  qualifications  that may be
appropriate.  In rendering its report such firm may rely, as to matters relating
to the  direct  servicing  of  commercial  and  multifamily  mortgage  loans  by
Sub-Servicers,  upon comparable reports of firms of independent certified public
accountants  rendered on the basis of examinations  conducted in accordance with
the same  standards  (rendered  within one year of such  report) with respect to
those Sub-Servicers.

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

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

     SECTION 3.15 Access to Certain Information.

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


                                       92

     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 on behalf of the  Certificateholders.  The
Special  Servicer,  on behalf of the Trust Fund,  shall  attempt to sell any REO
Property  within  two years of  acquiring  ownership  of such REO  Property  for
purposes of Section  860G(a)(8) of the Code,  unless the Special Servicer either
(i) is granted an extension of time (an "REO Extension") by the Internal Revenue
Service to sell such REO  Property or (ii) obtains for the Trustee an Opinion of
Counsel,  addressed to the Trustee and the Special Servicer,  to the effect that
the holding by the Trust Fund of such REO  Property  subsequent  to the close of
such period will not (subject to Section  10.01(f))  result in the imposition of
taxes on "prohibited  transactions" of REMIC I, REMIC II or REMIC III as defined
in Section  860F of the Code or cause  REMIC I, REMIC II or REMIC III to fail to
qualify as a REMIC (for federal (or any  applicable  state or local)  income tax
purposes)  at any time that any  Certificates  are  outstanding.  If the Special
Servicer  is  granted  the  REO  Extension  contemplated  by  clause  (i) of the
immediately preceding sentence or obtains the Opinion of Counsel contemplated by
clause (ii) of the immediately  preceding  sentence,  the Special Servicer shall
sell  such REO  Property  within  such  period  longer  than  three  years 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 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.


                                       93
<PAGE>


     (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.

     (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


                                       94
<PAGE>


     (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.

     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 




                                       95
<PAGE>


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 and maintenance 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 clauses (i) - (iv) above
with  respect to such REO  Property,  the Special  Servicer  shall  advance such
amount as is necessary  for such  purposes  (which  advances  shall be Servicing
Advances)  unless (as  evidenced  by an Officer's  Certificate  delivered to the
Trustee) such  advances  would,  if made,  constitute  Nonrecoverable  Servicing
Advances;  provided,  however,  that the  Special  Servicer  shall make any such
Servicing  Advance if it is a necessary  fee or expense  incurred in  connection
with the defense or  prosecution of legal  proceedings  and such advance will be
deemed to constitute a recoverable Servicing Advance.

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

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

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

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

     (iv) none of the  provisions of this Section  3.17(c)  relating to any such
contract or to actions taken through any such  Independent  Contractor  shall be
deemed to relieve  the  


                                       96
<PAGE>


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 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 



                                       97
<PAGE>


receipt of an Officer's  Certificate from the Master Servicer to the effect that
such deposit has been made,  shall release or cause to be released to the Master
Servicer or the Special Servicer, as applicable,  the related Mortgage File, and
shall execute and deliver such  instruments of transfer or  assignment,  in each
case without recourse, representation or warranty, as shall be necessary to vest
in the Master Servicer or the Special  Servicer,  as applicable,  such Defaulted
Mortgage Loan. In connection with any such purchase by the Master Servicer,  the
Special Servicer shall deliver the related Credit File to the Master Servicer.

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

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

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


                                       98
<PAGE>



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

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


                                       99
<PAGE>


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

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

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

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

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

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



                                      100
<PAGE>


shall be entitled to  reimbursement  for such  Advance,  together  with interest
thereon,  at the same time,  in the same  manner  and to the same  extent as the
Master  Servicer would otherwise have been entitled if it had actually made such
Servicing Advance.

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

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

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




                                      101
<PAGE>


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 lesser of (i) the aggregate of
all  Prepayment  Interest  Shortfalls  incurred  in  connection  with  Principal
Prepayments  received in respect of the Mortgage  Pool during the most  recently
ended Collection  Period,  and (ii) the aggregate Master Servicing Fees received
by the Master Servicer during such 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) 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 Loan. The foregoing shall not limit the Servicer and Special
Servicer's  obligation to establish a Lock-Box Account pursuant to Section 3.24.
If a Mortgagor  elects not to repay the principal due and  outstanding on an ARD
Loan on its  Anticipated  Repayment  Date, the Master  Servicer shall notify any
such Mortgagor that the Revised Rate for such Mortgage Loan shall not exceed the
related initial Mortgage Rate plus 2.00%.

     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 affect the amount or timing of any
related payment of principal, interest or other amount payable thereunder or, in
the Master Servicer's good faith and reasonable judgment,  materially impair the
security for such  Mortgage Loan or reduce the  likelihood of timely  payment of
amounts due thereon; the Special Servicer (in such capacity) may, however, agree
to any  modification,  waiver  or  amendment  of any term of, or take any of the
other acts  referenced  in this  Section  3.20(a)  with  respect to, a Specially
Serviced  Mortgage  Loan that  would have any such  effect,  but only if, in the
Special  Servicer's  reasonable and good faith judgment,  a material  default on
such  Mortgage  Loan has  occurred  or a default  in  respect of payment on such
Mortgage  Loan  is  reasonably  foreseeable,  and  such  modification,   waiver,
amendment or other action is reasonably  likely to produce a greater recovery to
Certificateholders on a present value basis, than would liquidation.

     (ii) With respect to the Senior  Living Loan,  the Master  Servicer and the
Special Servicer,  as applicable,  upon receipt of a Rating Agency Confirmation,
may  agree  to any  increase,  defeasance  or  revision  of the  Surety  Bond in
accordance  with the terms of the Surety Bond and the Senior Living  Subrogation
Agreement;

     (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;

     (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) 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  



                                      103
<PAGE>


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 (and
such  additional  environmental  testing  as  the  Master  Servicer  or  Special
Servicer,  as the case may be, deems necessary and  appropriate)  prepared by an
Independent  Person who regularly conducts  Environmental  Assessments (and such
additional  environmental  testing), at the expense of the Mortgagor,  that such
additional  or  substitute   collateral   is  in  compliance   with   applicable
environmental  laws and  regulations  and that  there  are no  circumstances  or
conditions  present  with  respect to such new  collateral  relating to the use,
management  or  disposal of any  Hazardous  Materials  for which  investigation,
testing,  monitoring,  containment,  clean-up or  remediation  would be required
under any then applicable environmental laws and/or regulations; and

     (vi) neither the Master Servicer nor the Special  Servicer shall release or
substitute  any  collateral  securing  an  outstanding  Mortgage  Loan except as
provided in Section  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 result in the downgrade,  qualification 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 (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

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 Special  Servicer and the
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

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

services  performed in connection  with such request,  together with any related
costs and expenses incurred by it.

     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

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

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,

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

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

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

     SECTION 3.22 Sub-Servicing Agreements.

     (a) The Master  Servicer and the Special  Servicer may each enter into Sub-
Servicing  Agreements for the servicing and  administration  of all or a part of

case, the Sub-Servicing  Agreement:  (i) is not inconsistent with this Agreement
and shall  provide that the  Sub-Servicer  will  maintain  


                                      106
<PAGE>


errors and  omissions  insurance  and fidelity  bond coverage as required of the
Master Servicer or the Special  Servicer  (whichever  retained it) under Section
3.07 hereof;  (ii) provides that if the Master Servicer or the Special Servicer,
as the case may be,  shall for any  reason no longer be the Master  Servicer  or
Special Servicer, as applicable,  hereunder (including,  without limitation,  by
reason of an Event of Default or their termination hereunder),  the Trustee, its
designee or any  successor  Master  Servicer or Special  Servicer may  thereupon
assume all of the rights and,  except to the extent they arose prior to the date
of assumption,  obligations of the Master Servicer or the Special  Servicer,  as
the case may be, under such agreement;  (iii) provides that any successor Master
Servicer may terminate such agreement  without cause and without  payment of any
termination fee; (iv) in the case of a Sub-Servicing  Agreement  entered into by
the Master  Servicer,  expressly  or  effectively  provides  that (if the Master
Servicer and the Special  Servicer are not the same Person) such agreement shall
terminate with respect to any Mortgage Loan serviced thereunder at the time such
Mortgage Loan becomes a Specially Serviced Mortgage Loan; and (v) in the case of
a Sub-Servicing Agreement entered into by the Special Servicer,  relates only to
Specially Serviced Mortgage Loans or REO Properties and expressly or effectively
provides that (if the Master Servicer and the Special  Servicer are not the same
Person) such  agreement  shall  terminate with respect to any such Mortgage Loan
that becomes a Corrected Mortgage Loan.  References in this Agreement to actions
taken or to be taken by the Master Servicer or the Special Servicer, as the case
may be, include  actions taken or to be taken by a Sub-Servicer on behalf of the
Master Servicer or the Special Servicer,  as the case may be; and, in connection
therewith,  all amounts  advanced by any Sub-Servicer to satisfy the obligations
of the Master Servicer or the Special Servicer, as the case may be, hereunder to
make Servicing  Advances and  Delinquency  Advances shall be deemed to have been
advanced by the Master Servicer or the Special Servicer, as the case may be, out
of its own funds and,  accordingly,  such Advances  shall be recoverable by such
Sub-Servicer  in  the  same  manner  and  out  of  the  same  funds  as if  such
Sub-Servicer were the Master Servicer or the Special  Servicer,  as the case may
be,  and,  for so long as they  are  outstanding,  such  Advances  shall  accrue
interest in accordance with Section 3.11(f) or Section  4.03(d),  as applicable,
such  interest  to be  allocable  between  the Master  Servicer  or the  Special
Servicer,  as the case may be,  and such  Sub-Servicer  as they may  agree.  For
purposes of this Agreement,  the Master  Servicer and the Special  Servicer each
shall be deemed to have received any payment when the Sub-Servicer receives such
payment.

     (b) Each Sub-Servicer shall be authorized to transact business in the state
or  states  in which the  related  Mortgaged  Properties  it is to  service  are
situated, if and to the extent required by applicable law.

     (c) As part of its servicing activities hereunder,  the Master Servicer and
the Special Servicer, for the benefit of the Trustee and the Certificateholders,
shall (at no expense to the Trustee, the  Certificateholders  or the Trust Fund)
monitor  the  performance  and  enforce  the  obligations  of each  Sub-Servicer
retained  by it under the related  Sub-Servicing  Agreement.  Such  enforcement,
including,  without limitation,  the legal prosecution of claims, termination of
Sub-Servicing  Agreements  in  accordance  with their  respective  terms and the
pursuit of other 


                                      107
<PAGE>


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.  The Master Servicer and the Special Servicer each
shall  have the right to  remove a  Sub-Servicer  retained  by it at any time it
considers such removal to be in the best interests of Certificateholders.

     (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
administering the Mortgage Loans for which it is responsible.

                      Certificateholder of the Controlling Class.

     The  Certificateholders  entitled  to more  than 50% of the  Voting  Rights

of the Certificates would be qualified,  downgraded or withdrawn; (ii) a written

that made the  designation) to the effect that the designation of such Person to
serve as Special  Servicer is in compliance with this Section 3.23 and all other
applicable provisions of this Agreement, that upon the execution and delivery of
the written acceptance referred to in the immediately preceding clause (ii), the
designated  Person shall be bound by the terms of this  Agreement  and that this
Agreement shall be enforceable  against the designated Person in accordance with
its  terms.  The  existing  Special  Servicer  shall be deemed to have  resigned
simultaneously  with such  designated  Person's  becoming  the Special  


                                      108

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

transfer  within two  Business  Days to the  replacement  Special  Servicer  for
administration  by it of all cash  amounts  that  shall at the time be or should
have been  deposited in the REO Account or delivered by the Special  Servicer to
the Master  Servicer or that are  thereafter  received with respect to Specially
Serviced Mortgage Loans and REO Properties.

     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

     (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 LockBox 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  LockBox
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.

                   Special Servicer.

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

GMACCM to perform its obligations under this Agreement.

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

than payments  thereunder in reimbursement of any Realized Losses and Additional
Trust Fund Expenses); and

     (iii) to reimburse REMIC III for any Realized  Losses and Additional  Trust
Fund  Expenses  previously  deemed  allocated  to  REMIC II  Regular  Interests,
apportioned as payment of Uncertificated  Principal Balance among the classes of
REMIC II Regular  Interests  such that the remaining  Uncertificated  Balance of
each such class will equal the Principal Balance of the corresponding  Principal
Balance Certificate after all subsequent payments made on such Distribution Date

and

     (xxxix) to pay to the Holders of the Class R-III  Certificates the balance,

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

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

          (i) to the  Holders of the Class A, Class B, Class C, Class D, Class E
     and Class F  Certificates  in an aggregate  amount up to the product of (a)
     such  Prepayment  Premiums,  (b) the  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).

     (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  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 



                                      119
<PAGE>


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

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

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

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



                                      120
<PAGE>


occurs,  mail to each  Holder of such  Class of  Certificates  as of the date of
mailing a notice to the effect that:

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

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

Any funds not distributed to any Holder or Holders of Certificates of such Class
on such  Distribution  Date  because of the failure of such Holder or Holders to
tender their Certificates, shall, on such date, be set aside and held uninvested
in  trust  and   credited  to  the  account  or  accounts  of  the   appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given  pursuant to this  Section  4.01(g)  shall not have been  surrendered  for
cancellation  within six months after the time  specified  in such  notice,  the
Trustee   shall   mail  a  second   notice   to  the   remaining   non-tendering
Certificateholders  to surrender their Certificates for cancellation in order to
receive the final  distribution  with respect thereto.  If within one year after
the second  notice all such  Certificates  shall not have been  surrendered  for
cancellation,  the Trustee,  directly or through an agent, shall take such steps
to  contact  the  remaining  nontendering   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.

     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. (215) 328-3478
(or such  alternative  number  provided by the Master Servicer to the Trustee in
writing) and by telephone at telephone  no. (215)  328-1790  (Attention:  Master
Servicing  Manager) (or such alternative  number provided by the Master Servicer
to the  Trustee in writing) as soon as  possible,  but in any event  before 5:00
p.m., New York City time, on such day. If after such notice the Trustee does not
receive the full  amount of such  Delinquency  Advances by 11:00 a.m.,  New York
City time,  on the  Business  Day  immediately  following  such Master  Servicer
Remittance  Date,  then the Trustee  shall make the portion of such  Delinquency
Advances  that was  required  to be, but 



                                      130
<PAGE>


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 related
Collection  Period  and  that  were  not  paid by or on  behalf  of the  related
Mortgagors or otherwise collected as of the close of business on 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


                                      131
<PAGE>


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
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.

     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,  a  Replacement  Mortgage  Loan,  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  



                                      132
<PAGE>


Balance  of the  corresponding  Class  of  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 Class Principal  Balances
of the  respective  Classes  of  Principal  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-16.  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
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,  Class E and Class F
Certificates,  $100,000  in the case of the 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) as  Certificate  Registrar for the purpose of
registering  



                                      134
<PAGE>


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

     (ii)  Notwithstanding the foregoing,  transfers of a beneficial interest in
any Class (or portion thereof) of Private Book-Entry  Certificates in accordance
with the rules and procedures of the  Depository  applicable to transfers by its
respective participants will be permitted if such transfer is made in accordance
with  Rule  144A  promulgated  under  the  Securities  Act.  Any  transfer  of a
beneficial  interest  in any Class (or portion  thereof)  of Private  Book-Entry
Certificates other than pursuant to Rule 144A, or to a transferee that wishes to
take delivery of such interest in definitive form, will be permitted upon:


                                      135
<PAGE>


     (A) receipt by the Trustee and the Depositor of the documentation  required
     by Section 5.02(b)(i)(A) or (B);

     (B) the execution by the Trustee,  and the  authentication  and delivery by
     the Certificate  Registrar to the transferee,  of a Definitive  Certificate
     representing such beneficial interest; and

     (C) to the extent that the beneficial  interest being  transferred does not
     represent the entire  Certificate  Principal  Balance of the related Class,
     either  (1)  the  execution  by the  Trustee,  and the  authentication  and
     delivery by the Certificate  Registrar to the Depository (upon surrender by
     the Depository of the prior Book-Entry Certificate) of, a new Private Book-
     Entry Certificate  representing the remaining  beneficial  interest of such
     Class of Private Book-Entry Certificates or (2) the appropriate notation by
     the Trustee on the Private Book-Entry Certificate or otherwise in its books
     and records as custodian  for the  Depository  evidencing  the date of such
     exchange or transfer  and a decrease in the  denomination  of such  Private
     Book-Entry   Certificate  equal  to  the  denomination  of  the  Definitive
     Certificate issued in exchange therefor or upon transfer thereof.

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

     (c) (i) No transfer of a Senior  Certificate or any interest  therein shall
be made  (A) to any  employee  benefit  plan or  other  retirement  arrangement,
including  individual  retirement  accounts  and  annuities,   Keogh  plans  and
collective  investment funds and separate accounts in which such plans, accounts
or  arrangements  are invested,  that is subject to ERISA or Section 4975 of the
Code  (each,  a  "Plan"),  or (B) to any Person who is  directly  or  indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with 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) 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  Subordinated  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



                                      136
<PAGE>


purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with assets of a Plan,  unless the prospective  transferee
provides the Depositor,  the Trustee and the Master  Servicer with an opinion of
counsel satisfactory to the Depositor,  the Trustee and the Master Servicer that
such transfer is permissible under applicable law, will not constitute or result
in any non-exempt prohibited transaction under ERISA or Section 4975 of the Code
and will not subject the  Depositor,  the Trustee or the Master  Servicer to any
obligation in addition to those  undertaken  herein.  In lieu of such opinion of
counsel, the prospective transferee of a Subordinated  Certificate may provide a
certification  of facts  substantially  to the effect that the  purchase of such
Certificate by or on behalf of, or with assets of, any Plan is permissible under
applicable  law,  will not  constitute  or result in any  non-exempt  prohibited
transaction  under  ERISA or  Section  4975 of the Code,  will not  subject  the
Depositor,  the Trustee or the Master  Servicer to any obligation in addition to
those undertaken 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. In addition, so long as any
portion  of the Class B, Class C, Class D, Class E, Class F, Class G and Class H
Certificates  are Book-Entry  Certificates,  any purchaser of such  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 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  of, as trustee  of, or with assets of a Plan.  The Trustee  shall not
have any  responsibility  to monitor  or  restrict  the  transfer  of  Ownership
Interests in any Subordinated  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



                                      137
<PAGE>


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.

          (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 



                                      138
<PAGE>


     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 noncomplying
     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, 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 



                                      139
<PAGE>


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 



                                      140
<PAGE>


to cover any tax or other governmental  charge that may be imposed in connection
with any transfer or exchange of Certificates.

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

     (j) The  Certificate  Registrar  shall be required to provide notice to the
Master  Servicer,  the Special  Servicer and the Depositor of each transfer of a
Certificate  and to  provide  each  such  Person  with  an  updated  copy of the
Certificate  Register on or about January 1 and July 1 of each year,  commencing
July 1, 1998.

     SECTION 5.03 Book-Entry Certificates.

     (a) Each  class  of  Registered  Certificates  and the  Private  Book-Entry
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 (and, with respect to the Private Book-Entry  Certificates,  except as
provided in Section  5.02(b)(ii)),  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 


                                      141
<PAGE>


reasonable  record date in  connection  with  solicitations  of consents from or
voting by  Certificateholders  and shall give notice to the  Depository  of such
record date.

     (c) If  (i)(A)  the  Depositor  advises  the  Trustee  and the  Certificate
Registrar  in  writing  that the  Depository  is no  longer  willing  or able to
properly  discharge  its   responsibilities   with  respect  to  the  Book-Entry
Certificates,  and (B) the Depositor is unable to locate a qualified  successor,
or (ii) the  Depositor  at its option  advises the  Trustee and the  Certificate
Registrar in writing that it elects to terminate the  book-entry  system through
the  Depository,  the Trustee shall notify all Certificate  Owners,  through the
Depository,  of the  occurrence  of any such  event and of the  availability  of
Definitive   Certificates  to  Certificate  Owners  requesting  the  same.  Upon
surrender to the  Certificate  Registrar of the Book-Entry  Certificates  by the
Depository,  accompanied by  registration  instructions  from the Depository for
registration  of  transfer  and any other  documents  necessary  to satisfy  the
requirements of any applicable transfer restrictions, the Trustee shall execute,
and the Certificate  Registrar shall  authenticate  and deliver,  the applicable
Definitive   Certificates   to  the  Certificate   Owners   identified  in  such
instructions.  None of the Depositor, the Master Servicer, the Special Servicer,
the Trustee,  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 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 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 



                                      144
<PAGE>


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

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

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

<PAGE>


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

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

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

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

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

Servicer under this Agreement or otherwise.

                                     DEFAULT

     (New York City time) on the relevant Distribution Date; provided,  however,
     that the Master Servicer will pay the Trustee interest on such late payment
     at the prime rate until such late payment is received by the Trustee; or

          (ii) any failure by the Special  Servicer to deposit into, or to remit
     to the Master Servicer for deposit into, the Certificate Account any amount
     required to be so deposited or remitted under this Agreement  which failure

     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

     Special Servicer contained in this Agreement which continues unremedied for
     a period of 30 days after the date on which written notice of such failure,
     requiring  the same to be  remedied,  shall  have been  given to the 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

                                      147
<PAGE>


     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

     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

     marshalling of assets and  liabilities or similar  proceedings,  or for the
     winding-up or liquidation of its affairs,  shall have been entered  against
     the Master Servicer or the Special  Servicer and such decree or order shall
     have remained in force undischarged or unstayed for a period of 60 days; or

     of assets and liabilities or similar proceedings of or relating to it or of
     or relating to all or substantially all of its property;

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

          (ix) the Trustee shall have received written notice from either Rating
     Agency 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.

     (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 



                                      148
<PAGE>


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 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 



                                      149
<PAGE>


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  Servicing  Fees  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 it is not  appropriately  rated  as a master
servicer  or  special  servicer,  as the case  may be,  by each  Rating  Agency,
promptly appoint any FNMA- or FHLMC-approved mortgage loan servicing institution
that has a net worth of not less than $10,000,000 and is otherwise acceptable to
each Rating Agency (as evidenced by written confirmation therefrom to the effect
that the  appointment  of such  institution  would not result in the  downgrade,
qualification  or  withdrawal  of its  rating  then  assigned  to any  Class  of
Certificates),  as the successor to the Master Servicer hereunder or the Special
Servicer,  as the  case  may be,  in the  assumption  of all or any  part of the
responsibilities,  duties or liabilities  of the Master  Servicer or the Special
Servicer,  as the case may be,  hereunder.  No appointment of a successor to the
Master Servicer or the Special Servicer,  as the case may be, hereunder shall be
effective  until the  assumption of the successor to the Master  Servicer or the
Special Servicer,  as the case may be, of all the  responsibilities,  duties and
liabilities of the Master Servicer or the Special Servicer,  as the case may be,
hereunder.  Pending  appointment  of a successor  to the 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.


                                      150

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

     SECTION 7.04   Waiver of Events of Default.

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

                                  ARTICLE VIII

                   CONCERNING THE TRUSTEE AND THE FISCAL AGENT

     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 or the Fiscal  Agent 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



                                      152
<PAGE>



     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  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 and the Fiscal Agent.

     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;

          (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 



                                      153
<PAGE>


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

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

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



                                      155
<PAGE>


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,  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 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
obligations  and duties  hereunder,  or by reason of reckless  disregard of such
obligations  or  duties,  or as may arise  from a breach of any  representation,
warranty or covenant of the Trustee made herein.  The provisions of this Section
8.05(b) shall survive any  resignation or removal of the Trustee and appointment
of a successor trustee 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 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  and "AA" by Fitch
(or, if not rated by Fitch, otherwise acceptable to Fitch as would not result in
a qualification,  downgrade or withdrawal of the rating assigned by Fitch to any
Class of Certificates)  or an equivalent  rating by each Rating Agency 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,  otherwise
acceptable  to  Fitch as would  not  result  in a  qualification,  downgrade  or
withdrawal  of the  rating  assigned  by  Fitch 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 "Aa2"
or an equivalent  rating by each Rating Agency 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, and



                                      156
<PAGE>


if in light of such  agreement the Trustee's  continuing to act in such capacity
would not (as  evidenced in writing by each rating  Agency)  cause either 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
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 or fiscal  agent.  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 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 



                                      157
<PAGE>


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 or fiscal
agent all such  rights,  powers,  duties  and  obligations,  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 or fiscal agent
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 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 



                                      159
<PAGE>


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 be qualified to do business in the jurisdiction in
which it holds any Mortgage File 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.

     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  NonRegistered  Certificate
belongs.  In addition,  if any such private  placement  memorandum or disclosure
document is revised,  amended or supplemented at any time following the delivery
thereof to the Trustee,  the Depositor promptly shall inform the Trustee of such
event and shall  deliver  to the  Trustee  ten copies of the  private  placement
memorandum or disclosure  document,  as revised,  amended or  supplemented.  The
Trustee shall maintain at its offices  primarily  responsible for  administering
the Trust Fund (or at the Primary  Servicing  Office of the Master 



                                      160

Servicer) and shall,  upon  reasonable  advance  notice,  make available  during
normal  business hours for review by any Holder of a  Certificate,  originals or

transferee of a Non-Registered Certificate,  any private placement memorandum or
other  disclosure  document  relating to the Class of Certificates to which such
Non-Registered  Certificate  belongs,  in the form most recently provided to the
Trustee;  and (ii) in all cases,  (A) this Agreement and any  amendments  hereto
entered into pursuant to Section 11.01, (B) all reports required to be delivered
to  Certificateholders  of the relevant Class pursuant to Section 4.02 since the

Section  3.12,  (F) as to each  Mortgage  Loan  pursuant  to which  the  related
Mortgagor is required to deliver such items or the Master Servicer has otherwise
acquired such items, the most recent annual operating statement and rent roll of
the related Mortgaged Property and financial statements of the related Mortgagor
collected by the Master  Servicer or the Special  Servicer and  delivered to the
Trustee  pursuant  to  Section  3.12(b),  (G) any and all  notices  and  reports
delivered  to the Trustee  with  respect to any  Mortgaged  Property  securing a
defaulted  Mortgage Loan as to which the environmental  testing  contemplated by
Section 3.09(c)  revealed that either of the conditions set forth in clauses (i)
and (ii) of the first  sentence  thereof was not satisfied (but only for so long
as such  Mortgaged  Property or the related  Mortgage Loan are part of the Trust
Fund), (H) the respective Mortgage Files, including, without limitation, any and
all  modifications,  waivers  and  amendments  of the terms of a  Mortgage  Loan
entered into by the Master Servicer or the Special Servicer and delivered to the
Trustee pursuant to Section 3.20 (but only for so long as the affected  Mortgage
Loan is part of the Trust Fund) and (I) any and all Officer's  Certificates  and
other  evidence  delivered  to or  retained by the Trustee to support the Master
Servicer's,  Special  Servicer's,  or Trustee's or Fiscal Agent's  determination
that any Advance was or, if made, would be a Nonrecoverable  Advance.  Copies of
any and all of the  foregoing  items will be  available  from the  Trustee  upon
request;  however, the Trustee shall be permitted to require from the requesting
Certificateholder  payment of a sum sufficient to cover the reasonable costs and
expenses of providing such copies.

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

reasonably satisfactory to the Trustee, generally to the effect that such Person

use in  evaluating  such  Person's  investment  in  the  Certificates  and  will
otherwise  keep  such  information  confidential  and  (b)  in  the  case  of  a
prospective purchaser, a written confirmation executed by the requesting Person,
in form  reasonably  satisfactory  to the Trustee,  generally to the effect that
such Person is a prospective  purchaser of a Certificate or an interest therein,
is requesting the information solely for use in evaluating a possible investment
in  Certificates  and will otherwise  keep such  information  confidential.  All
Certificateholders,  by the acceptance of their Certificates, shall be deemed to
have agreed to 



                                      161
<PAGE>


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

     (b) The Trustee shall provide or cause to be provided to the Depositor, the

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

     SECTION 8.13   Representations and Warranties of the Trustee and the Fiscal
                    Agent.

     (a) The Trustee hereby represents and warrants to the Master Servicer,  for

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

          (iii)  This  Agreement,  assuming  due  authorization,  execution  and
     delivery by the Special Servicer, the Master Servicer, the Fiscal Agent and
     the  Depositor,  constitutes a valid,  legal and binding  obligation of the
     Trustee,  enforceable  against  the  Trustee in  accordance  with the terms
     hereof,  subject  to  applicable  bankruptcy,  insolvency,  reorganization,

     adversely  the  ability of the Trustee to perform  its  obligations  or the
     financial condition or operations of the Trustee or its properties.

          (v) No  litigation  is  pending  or,  to  the  best  of the  Trustee's
     knowledge,  threatened against the Trustee which would prohibit the Trustee

     reasonable  judgment,  is likely to  materially  and  adversely  affect the
     ability of the Trustee to perform its obligations under this Agreement.

          (vi) No consent, approval,  authorization or order of, registration or
     filing with or notice to, any governmental  authority or court is required,

     the  Netherlands,  duly  organized,  validly  existing and in good standing
     under the laws governing its creation and existence.

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

          (iii)  This  Agreement,  assuming  due  authorization,  execution  and
     delivery by the Special Servicer,  the Master Servicer, the Trustee and the
     Depositor,  constitutes a valid, legal and binding obligation of the Fiscal
     Agent,  enforceable  against the Fiscal Agent in accordance  with the terms
     hereof,  subject  to  applicable  bankruptcy,  insolvency,  reorganization,
     moratorium  and other laws affecting the  enforcement of creditors'  rights

          (iv) The Fiscal  Agent is not in default  with respect to any order or
     decree of any court,  or any order,  regulation  or demand of any  federal,
     state,  municipal or  governmental  agency,  which  default,  in the Fiscal
     Agent's good faith and reasonable judgment,  is likely to affect materially

     obligations or the financial condition or operations of the Fiscal Agent or
     its properties.

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

          (vi) No consent, approval,  authorization or order of, registration or
     filing with or notice to, any governmental  authority or court is required,

     by the Fiscal Agent 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

                                   ARTICLE IX

                                   TERMINATION

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

     Subject to Section 9.02, the Trust Fund and the respective  obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Special  Servicer,  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's, living on the date hereof.

     The Master Servicer or the Depositor 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. 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


                                      166
<PAGE>


Distribution  Date on which the final  distribution  on the  Certificates  is to
occur,  an amount in immediately  available  funds equal to the  above-described
purchase price  (exclusive of any portion thereof would be payable to any Person
other than the  Certificateholders  pursuant to Section 3.05(a) if on deposit in
the  Certificate  Account,  which portion shall be deposited in the  Certificate
Account).  In addition,  the Master Servicer shall transfer to the  Distribution
Account all amounts  required to be transferred  thereto on such Master Servicer
Remittance Date from the Certificate  Account pursuant to the first 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
of  Certificates  so  presented  and  surrendered.  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)-(v) of Section 3.05(b)) shall be allocated for the purposes, in the amounts
and in  accordance  with the priority set forth in Section  4.01.  Any funds not
distributed on such  Distribution Date shall be set aside and held uninvested in
trust for the benefit of  Certificateholders  not  presenting  and  surrendering
their  Certificates  in the  aforesaid  manner,  and  shall  be  disposed  of in
accordance with the last paragraph of Section 4.01(g).

     SECTION 9.02   Additional Termination Requirements.

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

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

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

                           ADDITIONAL REMIC PROVISIONS

     SECTION 10.01  REMIC Administration.

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

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

     (c) The  Trustee,  as agent for the tax matters  person of each of REMIC I,
REMIC II and REMIC III,  shall (i) act on behalf of the REMIC in relation to any
tax matter or controversy  involving the Trust Fund and (ii) represent the Trust
Fund in any administrative or judicial  proceeding relating to an examination or
audit by any  governmental  taxing  authority  with respect  thereto.  The legal
expenses,  including  without  limitation  attorneys' or accountants'  fees, and
costs of any such  proceeding  and any liability  resulting  therefrom  shall be
expenses  of the Trust Fund and the Trustee  shall be entitled to  reimbursement
therefor  out of  amounts  attributable  to  the  Mortgage  Loans  and  any  REO
Properties on deposit in the Certificate  Account as provided by Section 3.05(a)
unless such legal  expenses  and costs are  incurred by reason of the  Trustee's
willful  misfeasance,  bad faith or negligence.  In the case of each of REMIC I,
REMIC II and REMIC III,  the Holder of Residual  Certificates  representing  the
largest Percentage Interest in the related Class thereof shall be designated, in
the manner provided under Treasury Regulations Section 1.860F-4(d) and temporary
Treasury Regulations Section 301.6231(a)(7)-1, as the tax matters person of such
REMIC.  By  its  acceptance  thereof,   the  Holder  of  Residual   Certificates
representing the largest Percentage Interest in each Class thereof 



                                      169
<PAGE>


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 each REMIC created hereunder.  The expenses of preparing such returns
shall be borne by the Trustee without any right of reimbursement therefor.

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

     (f) The Trustee  shall take such actions and shall cause each REMIC created
hereunder to take such actions as are  reasonably  within the Trustee's  control
and the scope of its  duties  more  specifically  set  forth  herein as shall be
necessary to maintain the status thereof as a REMIC under the REMIC  Provisions.
The Trustee shall not knowingly or intentionally take any action, cause REMIC I,
REMIC II or REMIC III to take any action or fail to take (or fail to cause to be
taken) any action  reasonably  within its  control  and the scope of duties more
specifically set forth herein, that, under the REMIC Provisions, if taken or not
taken, as the case may be, could (i) endanger 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  endanger 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  



                                      170
<PAGE>


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 the  Trust  Fund as  "qualified  mortgages"  as  defined  in  Section
860G(a)(3)  of the  Code and  "permitted  investments"  as  defined  in  Section
860G(a)(5) of the Code.

     (g) In the event that any tax is imposed on  "prohibited  transactions"  of
REMIC I, REMIC II or REMIC III as defined in Section  860F(a)(2) of the Code, on
"net  income  from  foreclosure  property"  of REMIC I, REMIC II or REMIC III as
defined in Section 860G(c) of the Code, 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 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 REMIC I, REMIC II or REMIC III  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
such  REMIC  will not cause such REMIC 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.


                                      171
<PAGE>


     (j) None of the Master Servicer,  the Special Servicer, the Fiscal Agent 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  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 11.01 Amendment.

     (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 (A) such
change shall not adversely affect the then-current  rating assigned to any Class
of  Certificates,  as  evidenced  by a letter  from each  Rating  Agency to such
effect,  and (B) 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


                                      173
<PAGE>


     (vi) 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.

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.

     (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

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.

the  counties  or other  comparable  jurisdictions  in  which  any or all of the
properties  subject to the Mortgages are situated,  and in any other appropriate
public  recording  office or elsewhere,  such  recordation to be effected by the
Master  Servicer at the expense of the Trust Fund on  direction  by the Trustee,
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.

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
or any of them.

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

be construed so as to  constitute  the  Certificateholders  from time to time as
partners or members of an association;  nor shall any Certificateholder be under
any liability to any third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

     (c) No Certificateholder shall have any right by virtue of any provision of
this  Agreement to institute any suit,  action or proceeding in equity or at law

proceeding  upon  or  under  or with  respect  to 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 Percentage
Interests  in such Class  shall have made  written  request  upon the Trustee to
institute such action,  suit or proceeding in its own name as Trustee  hereunder

institute,  conduct or defend any litigation  hereunder or in relation hereto at
the request,  order or direction  of any of the Holders of  Certificates  unless
such Holders have offered to the Trustee reasonable  security against the costs,
expenses  and  liabilities  which  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  Certificates,  or to  obtain  or seek to  obtain
priority  over or  preference  to any  other  such  Holder,  which  priority  or
preference is not otherwise  provided for herein, 

     SECTION 11.04  GOVERNING LAW.

Certificate as such address last appeared in the Certificate  Register or to any
such other address of which the Trustee is subsequently notified in writing.

without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, Class A-2
Certificates  are  exchangeable  for new Class A-2  Certificates  in  authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

     As provided in the Agreement and subject to certain limitations therein set
forth,  the  transfer of this  Certificate  is  registrable  in the  Certificate
Register upon surrender of this  Certificate for registration of transfer at the
offices of the  Certificate  Registrar,  duly endorsed by, or  accompanied  by a
written  instrument  of transfer  in the form  satisfactory  to the  Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing,  and  thereupon  one or more new Class A-2  Certificates  in authorized
denominations  evidencing the same aggregate  Percentage Interest will be issued
to the designated transferee or transferees.

     No transfer of a Senior  Certificate or any interest  therein shall be made
(i) to any employee  benefit  plan or other  retirement  arrangement,  including
individual  retirement  accounts  and  annuities,  Keogh  plans  and  collective
investment  funds  and  separate  accounts  in which  such  plans,  accounts  or
arrangements are invested,  that is subject to ERISA or Section 4975 of the Code
(each, a "Plan"), or (ii) 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 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 GMAC and certain of its  affiliates)  and (2) at the time of
such transfer,  the Senior  Certificates  continue to be rated in one of the top

may require  payment of a sum sufficient to cover any tax or other  governmental
charge that may be imposed in connection  with any transfer or exchange of Class
A-2 Certificates.

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

     The Trust Fund and the obligations created by the Agreement shall terminate

all amounts held by or on behalf of the Trustee and  required to be  distributed
to them pursuant to the Agreement following the earlier of (i) the final payment
or other  liquidation (or any advance with respect thereto) of the last Mortgage

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the

Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any

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

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

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

any purchaser of such  Certificates  will be deemed to have  represented by such
purchase that either (a) such purchaser is not a Plan and is not purchasing such

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,  the Master Servicer,  the Special Servicer,  the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 662/3% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this  Certificate  shall be  conclusive  and binding on
such  Holder  and  upon  all  future  Holders  of  this  Certificate  and of any
Certificate  issued upon the transfer  hereof or in exchange  herefor or in lieu
hereof  whether or not notation of such  consent is made upon this  Certificate.
The Agreement  also permits the  amendment  thereof,  in certain  circumstances,
including any amendment  necessary to maintain the status of designated portions
of the Trust Fund as a REMIC,  without  the consent of the Holders of any of the
Certificates.

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

this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  distributions  will be made on the

is  registered  at the close of business on the last  Business  Day of the month
immediately  preceding the month of such distribution (the "Record Date"), in an

the  Agreement or such other  location as may be specified in such notice.  Also
notwithstanding the foregoing, any distribution that may be made with respect to
this  Certificate in reimbursement of any Realized Loss or Additional Trust Fund
Expense  previously  allocated to this  Certificate,  which  reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the  preceding  sentence,  will be made by check  mailed to the  address  of the
Holder that  surrenders  this  Certificate  as such address last appeared in the
Certificate  Register  or to any such  other  address  of which the  Trustee  is

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

     The Depositor's  Mortgage  Pass-Through  Certificates,  Series 1998-C1 (the

Certificate  Account and the Distribution  Account may be made from time to time
for purposes  other than,  and, in certain  cases,  prior to,  distributions  to
Certificateholders,  such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

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

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


 
                                      A-5-3

<PAGE>



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 Servicer to any
obligation in addition to those  undertaken in the Agreement,  and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an "insurance  company general  account" (as such term is defined in 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 Class C  Certificate  that is
held as a Definitive Certificate, provide such certifications as the Trustee may
deem  desirable or necessary in order to establish  that such  transferee or the
Person in whose name such  registration  is  requested is not a Plan or a Person
who is directly or indirectly purchasing such Certificate on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan.

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

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

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

the Holder surrendering the same.

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

     No transfer of a Class D Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including

(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the
Class D Certificate or interest  therein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan, unless the prospective transferee provides
the Trustee,  the Fiscal Agent,  the Master  Servicer and the  Depositor  with a
certification  of  facts  and an  Opinion  of  Counsel  which  establish  to the
satisfaction  of the  Trustee,  the Fiscal  Agent,  the Master  Servicer and the
Depositor  that such  transfer is  permissible  under  applicable  law, will not
constitute  or result in a violation  of Section 406 of ERISA or Section 4975 of
the Code and will not subject the  Depositor,  the Trustee,  the Fiscal Agent or
the Master  Servicer to any  obligation  in addition to those  undertaken in the
Agreement.  In lieu of such opinion of counsel, the prospective  transferee of a
Class D Certificate may provide a certification  of facts  substantially  to the
effect that the purchase of such  Certificate by or on behalf of, or with assets
of, any Plan is permissible  under applicable law, will not constitute or result
in any  non-exempt  prohibited  transaction  under ERISA or Section  4975 of the
Code,  will not subject the  Depositor,  the  Trustee,  the Fiscal  Agent or the
Master  Servicer  to any  obligation  in  addition  to those  undertaken  in the
Agreement, and the following conditions are met: (a) the source of funds used to
purchase such  Certificate is an "insurance  company  general  account" (as such
term is defined in United  States  Department  of Labor  Prohibited  Transaction
Class  Exemption  ("PTCE") 95-60) and (b) the conditions set forth in Sections I
and III of PTCE 95-60 have been  satisfied as of the date of the  acquisition of
such  Certificate.  In  addition,  so long as the Class D  Certificates  (or any
portion  thereof) are  registered  in the name of Cede & Co., as nominee of DTC,
any purchaser of such  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

Trustee, the Fiscal Agent or the Servicer to any obligation in addition to those
undertaken  in the  Agreement,  and the  following  conditions  are met: (a) the
source of funds used to  purchase  such  Certificate  is an  "insurance  company
general  account" (as such term is defined in 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 Class D  Certificate  that is held as a Definitive
Certificate,  provide such  certifications  as the Trustee may deem desirable or
necessary in order to establish that such transferee or the Person in whose name
such  registration  is  requested  is not a Plan or a Person who is  directly or
indirectly  purchasing such  Certificate on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan.

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

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

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

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

satisfied as of the date of the  acquisition of such  Certificates.  The Trustee
may require that any  prospective  transferee of a Class E  Certificate  that is

name such registration is requested is not a Plan or a Person who is directly or
indirectly  purchasing such  Certificate on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan.

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

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

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

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

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

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 in the  Agreement,  and the

in United States  Department of Labor  Prohibited  Transaction  Class  Exemption
("PTCE")  95-60) and (b) the  conditions set forth in Sections I and III of PTCE
95-60 have been satisfied as of the date of the acquisition of such Certificate.
In addition,  so long as the Class F Certificates  (or any portion  thereof) are

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

in whose name such  registration  is  requested is not a Plan or a Person who is
directly  or  indirectly  purchasing  such  Certificate  on behalf  of, as named
fiduciary of, as trustee of, or with assets of a Plan.

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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

all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

     The Trust Fund and the obligations created by the Agreement shall terminate

to them pursuant to the Agreement following the earlier of (i) the final payment
or other  liquidation (or any advance with respect thereto) of the last Mortgage
Loan or REO Property  remaining in the Trust Fund,  and (ii) the purchase by the
Master  Servicer  or the  Depositor  at a price  determined  as  provided in the
Agreement of all Mortgage  Loans and any REO  Properties  remaining in the Trust
Fund. The Agreement permits,  but does not require,  the Depositor or the Master

Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class G  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as
Exhibit B-2 to the  Agreement;  and (ii) in all other cases,  (A) a  certificate

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).  Notwithstanding
the foregoing,  so long as the Class G Certificates (or any portion thereof) are
registered  in the  name of  Cede & Co.,  as  nominee  of  DTC,  transfers  of a
beneficial  interest  therein in accordance with the rules and procedures of the
Depository  applicable  to  transfers  by its  respective  participants  will be
permitted  if such  transfer is made in  accordance  with Rule 144A  promulgated
under the Securities  Act. Any transfer of a beneficial  interest in any Class G
Certificate  that is  registered  in the name of Cede & Co.,  as nominee of DTC,
other  than  pursuant  to Rule  144A,  or to a  transferee  that  wishes to take
delivery of such  interest in  definitive  form,  will be  permitted  upon:  (A)
receipt by the  Trustee  and the  Depositor  of the  documentation  required  by
Section 5.02(b)(i)(A) or (B) of the Agreement; (B) the execution by the Trustee,
and  the  authentication  and  delivery  by  the  Certificate  Registrar  to the
transferee,  of a Definitive Certificate  representing such beneficial interest;
and (C) to the extent that the beneficial  interest being  transferred  does not
represent the entire Certificate  Principal Balance of the Class G Certificates,
the  execution  by the  Trustee,  and the  authentication  and  delivery  by the
Certificate  Registrar to the Depository of, a Class G Certificate  representing
the  remaining  beneficial  interest of such Class G  Certificates.  None of the
Depositor,  the  Trustee,  the  Fiscal  Agent or the  Certificate  Registrar  is
obligated to register or qualify the Class G  Certificates  under the Securities
Act or any other  securities  law or to take any action not  otherwise  required
under the  Agreement to permit the transfer of any Class G  Certificate  without
registration or qualification.  Any Class G Certificateholder desiring to effect
such a transfer shall,  and by the acceptance of its Class G Certificate  agrees
to, indemnify the Depositor,  the Trustee,  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.

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

thereof)  are  registered  in the name of Cede & Co.,  as  nominee  of DTC,  any
purchaser  of such  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 Servicer to any
obligation in addition to those  undertaken in the Agreement,  and the following
conditions are met: (a) the source of funds used to purchase such Certificate is
an "insurance  company general  account" (as such term is defined in 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 Class G  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

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

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

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).  None of the
Depositor,  the  Trustee,  the  Fiscal  Agent or the  Certificate  Registrar  is
obligated to register or qualify the Class H  Certificates  under the Securities
Act or any other  securities  law or to take any action not  otherwise  required

registration or qualification.  Any Class H Certificateholder desiring to effect
such a transfer shall,  and by the acceptance of its Class H Certificate  agrees
to, 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.

(each, a "Plan") or (B) any Person who is directly or indirectly  purchasing the

certification  of  facts  and an  Opinion  of  Counsel  which  establish  to the
satisfaction  of the  Trustee,  the Fiscal  Agent,  the Master  Servicer and the
Depositor  that such  transfer is  permissible  under  applicable  law, will not
constitute or result in any non-exempt prohibited  transaction under Section 406
of ERISA or Section  4975 of the Code and will not  subject the  Depositor,  the
Trustee,  the Fiscal Agent or the Master  Servicer to any obligation in addition
to those  undertaken in the Agreement.  In lieu of such opinion of counsel,  the
prospective  transferee of a Class H Certificate may provide a certification  of
facts substantially to the effect that the purchase of such Certificate by or on
behalf of, or with assets of, any Plan is permissible under applicable law, will
not constitute or result in any non-exempt prohibited transaction under ERISA or
Section  4975 of the Code,  will not subject the  Depositor,  the  Trustee,  the
Fiscal  Agent or the Master  Servicer  to any  obligation  in  addition to those
undertaken in the Agreement, and the following conditions are met (a) the source
of funds used to purchase  such  Certificate  is an "insurance  company  general
account"  (as  such  term is  defined  in  United  States  Department  of  Labor
Prohibited  Transaction  Class Exemption  ("PTCE") 95-60) and (b) the conditions
set forth in Sections I and III of PTCE 95-60 have been satisfied as of the date
of the acquisition of such Certificate.

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

     Notwithstanding  the  foregoing,   for  so  long  as  this  Certificate  is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC,  transfers of interests in this  Certificate
shall be made through the book-entry facilities of DTC.

all purposes, and none

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

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

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

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

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

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

that  certain  beneficial  ownership  interest  evidenced  by all  the  Class  J

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

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

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

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

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


 
                                     A-11-3

or  qualify  the  Class J  Certificates  under the  Securities  Act or any other
securities law or to take any action not otherwise  required under the Agreement
to permit  the  transfer  of any Class J  Certificate  without  registration  or
qualification.  Any Class J Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class J Certificate agrees to, indemnify the
Depositor,  the Trustee, 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.

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

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

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

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,  the Master Servicer,  the Special Servicer,  the Trustee
and the Fiscal Agent with the consent of the Holders of


 
                                     A-11-4

<PAGE>


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

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

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

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

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

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

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


 
                                     A-12-3

or  qualify  the  Class K  Certificates  under the  Securities  Act or any other
securities law or to take any action not otherwise  required under the Agreement
to permit  the  transfer  of any Class K  Certificate  without  registration  or
qualification.  Any Class K Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class K Certificate agrees 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.

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

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

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,  the Master Servicer,  the Special Servicer,  the Trustee
and the Fiscal Agent with the consent of the Holders of


 
                                     A-12-4

<PAGE>


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

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

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

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

coupons in minimum denominations  specified in the Agreement. As provided in the
Agreement  and  subject  to  certain  limitations  therein  set  forth,  Class L

Register upon surrender of this  Certificate for registration of transfer at the
offices of the  Certificate  Registrar,  duly endorsed by, or  accompanied  by a
written  instrument  of transfer  in the form  satisfactory  to the  Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in

denominations  evidencing the same aggregate  Percentage Interest will be issued
to the designated transferee or transferees.

is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class L  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in

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

Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class  L  Certificate  without  registration  or  qualification.   Any  Class  L
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class L Certificate  agrees 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.

     No transfer of a Class L Certificate or any interest  therein shall be made
to (A) any employee  benefit  plan or other  retirement  arrangement,  including

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

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

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,

future  Holders  of this  Certificate  and of any  Certificate  issued  upon the

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

     Unless the  certificate of  authentication  hereon has been executed by the
Certificate  Registrar,  by  manual  signature,  this  Certificate  shall not be

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

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

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

     No transfer of any Class M  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class M  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the

attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as

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

Certificates under the Securities Act or any other securities law or to take any
action not otherwise  required under the Agreement to permit the transfer of any
Class  M  Certificate  without  registration  or  qualification.   Any  Class  M
Certificateholder  desiring  to  effect  such  a  transfer  shall,  and  by  the
acceptance of its Class M Certificate  agrees 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.

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

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

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,

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

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

     No transfer of any Class N  Certificate  shall be made unless that transfer
is made pursuant to an effective  registration  statement  under the  Securities
Act,  and  effective   registration  or  qualification  under  applicable  state
securities  laws,  or is  made in a  transaction  that  does  not  require  such
registration  or  qualification.  If such a transfer of any Class N  Certificate
(other  than a  transfer  thereof  by the  Depositor  or  any  Affiliate  of the
Depositor) is to be made without registration under the Securities Act, then the
Trustee shall require,  in order to assure compliance with such laws, receipt by
it and the  Depositor  of: (i) if such  transfer  is  purportedly  being made in
reliance  upon Rule 144A  under  the  Securities  Act,  a  certificate  from the
Certificateholder  desiring to effect such  transfer  substantially  in the form
attached  as  Exhibit  B-1  to  the  Agreement  and  a  certificate   from  such
Certificateholder's prospective transferee substantially in the form attached as

from the Certificateholder desiring to effect such transfer substantially in the
form  attached  to the  Agreement  as Exhibit  B-1 and a  certificate  from such
Certificateholder's prospective transferee substantially in the form attached to

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).  None of the
Depositor,  the  Trustee,  the  Fiscal  Agent or the  Certificate  Registrar  is
obligated to register or qualify the Class N  Certificates  under the Securities
Act or any other securities law or to take any action not

otherwise  required  under the  Agreement  to permit the transfer of any Class N
Certificate without registration or qualification. Any Class N Certificateholder
desiring to effect such a transfer  shall,  and by the acceptance of its Class N
Certificate  agrees 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.

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

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

     Prior to due presentment of this  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 this  Certificate is registered as the owner hereof for
all  purposes,  and none of the  Depositor,  the Master  Servicer,  the  Special
Servicer,  the Trustee, the Fiscal Agent, the Certificate  Registrar or any such
agent shall be affected by notice to the contrary.

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

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment  thereof,  and the  modification  of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent  thereunder and the rights of the  Certificateholders  thereunder,  at any
time by the Depositor,  the Master Servicer,  the Special Servicer,  the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66 2/3% of the Voting  Rights  allocated to the affected  Classes.  Any
such consent by


 
                                     A-15-4

<PAGE>



the Holder of this  Certificate  shall be conclusive  and binding on such Holder
and upon all future Holders of this  Certificate and of any  Certificate  issued
upon the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation  of such  consent is made upon this  Certificate.  The  Agreement  also
permits the amendment thereof, in certain circumstances, including any amendment
necessary to maintain the status of  designated  portions of the Trust Fund as a
REMIC, without the consent of the Holders of any of the Certificates.

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

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

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

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

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

Agreement.  All  distributions  made  under  the  Agreement  on  any  Class  R-I

     The Depositor's  Mortgage  Pass-Through  Certificates,  Series 1998-C1 (the

Certificate  Account and Distribution  Account may be made from time to time for
purposes  other  than,  and,  in  certain  cases,  prior  to,  distributions  to

of interest on such advances and expenses.

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

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

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

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

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

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


 
                                     A-16-3

<PAGE>



is not  acquiring  its  Ownership  Interest  in this  Certificate  as a nominee,
trustee or agent for any Person that is not a Permitted  Transferee  or is not a
United States Person,  that for so long as it retains its Ownership  Interest in
this Certificate, it will endeavor to remain a Permitted Transferee and a United
States Person, and that it has reviewed the provisions of Section 5.02(d) of the
Agreement  and agrees to be bound by them.  Notwithstanding  the  delivery  of a
Transfer  Affidavit and Agreement by a proposed  Transferee,  if the Trustee has
actual knowledge that the proposed  Transferee is not a Permitted  Transferee or
is not a United States Person, the Trustee shall not register the Transfer of an
Ownership Interest in this Certificate to such proposed Transferee.

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

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

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

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

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

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

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

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

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

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

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

Mortgage Securities,  Inc., as Depositor,  GMAC Commercial Mortgage Corporation,
as Master Servicer and Special  Servicer,  LaSalle National Bank, as Trustee and

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

     Pursuant to the terms of the Agreement,  distributions  will be made on the

Day immediately  following  (each, a "Distribution  Date"),  commencing upon the
First  Distribution  Date  specified  above,  to the  Person in whose  name this
Certificate  is  registered at the close of business on the last Business Day of
the month immediately  preceding the month of such distribution (as to the Class

Percentage  Interest evidenced by this Certificate and the amount required to be

of interest on such advances and expenses.

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

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

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

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

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


 
                                     A-17-3

<PAGE>



is not  acquiring  its  Ownership  Interest  in this  Certificate  as a nominee,
trustee or agent for any Person that is not a Permitted  Transferee  or is not a
United States Person,  that for so long as it retains its Ownership  Interest in
this Certificate, it will endeavor to remain a Permitted Transferee and a United
States Person, and that it has reviewed the provisions of Section 5.02(d) of the
Agreement  and agrees to be bound by them.  Notwithstanding  the  delivery  of a
Transfer  Affidavit and Agreement by a proposed  Transferee,  if the Trustee has
actual knowledge that the proposed  Transferee is not a Permitted  Transferee or
is not a United States Person, the Trustee shall not register the Transfer of an
Ownership Interest in this Certificate to such proposed Transferee.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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


 
                                     A-18-3

<PAGE>



and Agreement") from the proposed Transferee, in form and substance satisfactory
to the Trustee,  representing  and  warranting,  among other  things,  that such
Transferee is a Permitted  Transferee and a United States Person, that it is not
acquiring its Ownership  Interest in this  Certificate as a nominee,  trustee or
agent  for any  Person  that is not a  Permitted  Transferee  or is not a United
States  Person,  that for so long as it retains its  Ownership  Interest in this
Certificate,  it will  endeavor  to remain a Permitted  Transferee  and a United
States Person, and that it has reviewed the provisions of Section 5.02(d) of the
Agreement  and agrees to be bound by them.  Notwithstanding  the  delivery  of a
Transfer  Affidavit and Agreement by a proposed  Transferee,  if the Trustee has
actual knowledge that the proposed  Transferee is not a Permitted  Transferee or
is not a United States Person, the Certificate  Registrar shall not register the
Transfer  of  an  Ownership  Interest  in  this  Certificate  to  such  proposed
Transferee.

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

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

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

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

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

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

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

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

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

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

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

                    [K] [L] [M] [N], having an initial  principal  balance as of
                    May 1, 1998 of $___________

Dear Sirs:

     This letter is  delivered  to you in  connection  with the transfer by (the
"Transferor") to ____________  (the  "Transferee") of the captioned  Certificate
(the  "Certificate"),  pursuant to Section  5.02 of the  Pooling  and  Servicing
Agreement  (the  "Pooling and  Servicing  Agreement"),  dated as of May 1, 1998,
among GMAC Commercial Mortgage  Securities,  Inc. as Depositor,  GMAC Commercial
Mortgage Corporation,  as Master Servicer and Special Servicer, LaSalle National
Bank, as Trustee and ABN AMRO Bank N.V., as Fiscal Agent.  All terms used herein
and not otherwise  defined shall have the  respective  meanings set forth in the
Pooling and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Certificate Registrar, that:

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

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

     3. The Transferor and any person acting on behalf of the Transferor in this
matter  reasonably  believe that the  Transferee  is a "qualified  institutional
buyer" (as that term is defined in Rule 144A ("Rule 144A") under the  Securities
Act) purchasing for its own account.  In determining whether the Transferee is a
"qualified  institutional buyer," the Transferor and any person acting on behalf
of the  Transferor  in this matter has relied upon the  following  method(s)  of
establishing  the  Transferee's  ownership  and  discretionary   investments  of
securities (check one or more):


 

<PAGE>



     __  (a)  The  Transferee's   most  recent  publicly   available   financial
statements,  which  statements  present the  information  as of a date within 16
months  preceding  the  date of sale of the  Certificate  in the  case of a U.S.
purchaser  and  within  18  months  preceding  such  date of sale for a  foreign
purchaser; or

     __  (b)  The  most  recent  publicly  available  information  appearing  in
documents filed by the Transferee with the Securities and Exchange Commission or
another  United  States  federal,   state,  or  local  governmental   agency  or
self-regulatory   organization,   or  with  a  foreign  governmental  agency  or
self-regulatory organization, which information is as of a date within 16 months
preceding the date of sale of the  Certificate  in the case of a U.S.  purchaser
and within 18 months preceding such date of sale for a foreign purchaser; or

     __ (c) The  most  recent  publicly  available  information  appearing  in a
recognized securities manual, which information is as of a date within 16 months
preceding the date of sale of the  Certificate  in the case of a U.S.  purchaser
and within 18 months preceding such date of sale for a foreign purchaser; or

     __ (d) A certification by the chief financial  officer, a person fulfilling
an equivalent function, or other executive officer of the Transferee, specifying
the amount of  securities  owned and  invested on a  discretionary  basis by the
Transferee as of a specific date on or since the close of the Transferee's  most
recent  fiscal  year,  or,  in the case of a  Transferee  that is a member  of a
"family of  investment  companies,"  as that term is  defined  in Rule  144A,  a
certification by an executive officer of the investment  adviser  specifying the
amount of  securities  owned by the  "family of  investment  companies"  as of a
specific date on or since the close of the Transferee's most recent fiscal year.

     4. The  Transferor  and any  person  acting  on  behalf  of the  Transferor
understand  that in  determining  the aggregate  amount of securities  owned and
invested on a  discretionary  basis by an entity for  purposes  of  establishing
whether such entity is a "qualified institutional buyer:"

          (a)  the  following  instruments  and  interests  shall  be  excluded:
     securities of issuers that are affiliated with the  Transferee;  securities
     that are part of an unsold  allotment to or subscription by the Transferee,
     if the  Transferee is a dealer;  securities of issuers that are part of the
     Transferee's  "family of  investment  companies,"  if the  Transferee  is a
     registered  investment  company;  bank deposit  notes and  certificates  of
     deposit; loan participations;  repurchase agreements;  securities owned but
     subject  to  a  repurchase  agreement;  and  currency,  interest  rate  and
     commodity swaps;

          (b) the aggregate  value of the  securities  shall be the cost of such
     securities,  except where the entity reports its securities holdings in its
     financial  statements  on the basis of their market  value,  and no current
     information  with  respect  to  the  cost  of  those  securities  has  been
     published, in which case the securities may be valued at market; and

          (c)  securities   owned  by   subsidiaries  of  the  entity  that  are
     consolidated  with the  entity  in its  financial  statements  prepared  in
     accordance with generally accepted accounting principles may be included if
     the investments of such subsidiaries are managed under the direction of the
     entity, except that, unless the entity is a reporting company under Section
     13 or 15(d) of the  Securities  Exchange Act of 1934,  securities  owned by
     such   subsidiaries  may  not  be  included  if  the  entity  itself  is  a
     majority-owned  subsidiary  that  would  be  included  in the  consolidated
     financial statements of another enterprise.

     5. Unless the Transferee is an "accredited  investor" within the meaning of
Rule 501(a) (1), (2), (3), or (7) that is furnishing a Transferee Certificate in
the form of Exhibit B-3 to the Pooling and Servicing  Agreement,  the Transferor
or a person acting on its behalf has taken  reasonable  steps to ensure that the
Transferee is aware that the  Transferor  is relying on the  exemption  from the
provisions of Section 5 of the Securities Act provided by Rule 144A.

     6. The Transferor or a person acting on its behalf has furnished, or caused
to be furnished, to the Transferee all information regarding (a) the Certificate
and  distributions  thereon,  (b) the nature,  performance  and servicing of the
Mortgage  Loans,  (c) the Pooling and  Servicing  Agreement,  and (d) any credit
enhancement  mechanism associated with the Certificate,  that the Transferee has
requested.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

          [For Transferees Other Than Registered Investment Companies]

     The undersigned  hereby  certifies as follows to [name of Transferor]  (the
"Transferor")  and [name of Certificate  Registrar],  as Certificate  Registrar,
with  respect  to the  mortgage  pass-through  certificate  (the  "Certificate")
described in the Transferee  Certificate to which this certification relates and
to which this certification is an Annex:

     1. As indicated  below, the undersigned is the chief financial  officer,  a
person  fulfilling an equivalent  function,  or other  executive  officer of the
entity purchasing the Certificate (the "Transferee").

     2. The  Transferee  is a  "qualified  institutional  buyer" as that term is
defined in Rule 144A under the Securities Act of 1933 ("Rule 144A"), because (i)
the Transferee owned and/or invested on a discretionary  basis  $_______________
1/ in securities  (other than the excluded  securities  referred to below) as of
the  end  of the  Transferee's  most  recent  fiscal  year  (such  amount  being
calculated in accordance  with Rule 144A) and (ii) the Transferee  satisfies the

     official or is a foreign  bank or  equivalent  institution,  and (b) has an
     audited net worth of at least  $25,000,000  as  demonstrated  in its latest

     of sale for a foreign bank or equivalent institution.

     __ Savings and Loan. The Transferee (a) is a savings and loan  association,

     savings  and loan  association  or  equivalent  institution  and (b) has an
     audited net worth of at least  $25,000,000  as  demonstrated  in its latest
     annual financial  statements,  a copy of which is attached hereto,  as of a
     date not more than 16 months  preceding the date of sale of the Certificate
     in the case of a U.S.  savings and loan  association,  and not more than 18
     months  preceding  such  date  of  sale  for a  foreign  savings  and  loan
     association or equivalent institution.

     __ Broker-dealer. The Transferee is a dealer registered pursuant to Section
     15 of the Securities Exchange Act of 1934.

     __ Insurance Company.  The Transferee is an insurance company whose primary
     and  predominant  business  activity  is the  writing of  insurance  or the
     reinsuring  of risks  underwritten  by  insurance  companies  and  which is
     subject to supervision by the insurance  commissioner or a similar official
     or agency of a State, U.S. territory or the District of Columbia.

- ----------
1/  Transferee  must  own  and/or  invest  on a  discretionary  basis  at  least
$100,000,000  in securities  unless  Transferee is a dealer,  and, in that case,
Transferee must own and/or invest on a discretionary  basis at least $10,000,000
in securities.


 
                                      B-2-4

<PAGE>



     __ State or Local Plan. The Transferee is a plan established and maintained
     by a State, its political subdivisions, or any agency or instrumentality of
     the State or its political subdivisions, for the benefit of its employees.

     __ ERISA  Plan.  The  Transferee  is an  employee  benefit  plan within the
     meaning of Title I of the Employee Retirement Income Security Act of 1974.

     __ Investment  Advisor.  The Transferee is an investment advisor registered
     under the Investment Advisers Act of 1940.

     __  Other.  (Please  supply  a  brief  description  of  the  entity  and  a
     cross-reference  to the paragraph and subparagraph  under subsection (a)(1)
     of  Rule  144A  pursuant  to  which  it  qualifies.  Note  that  registered
     investment companies should complete Annex 2 rather than this Annex 1.)

     3. The term  "securities" as used herein does not include (i) securities of
issuers that are affiliated with the  Transferee,  (ii) securities that are part
of an unsold  allotment to or subscription by the Transferee,  if the Transferee
is a dealer,  (iii) bank deposit notes and  certificates  of deposit,  (iv) loan
participation, (v) repurchase agreements, (vi) securities owned but subject to a
repurchase agreement and (vii) currency,  interest rate and commodity swaps. For
purposes of determining the aggregate amount of securities owned and/or invested
on a discretionary  basis by the Transferee,  the Transferee did not include any
of the securities referred to in this paragraph.

     4. For purposes of  determining  the aggregate  amount of securities  owned
and/or invested on a discretionary basis by the Transferee,  the Transferee used
the cost of such securities to the Transferee, unless the Transferee reports its
securities  holdings in its  financial  statements  on the basis of their market
value,  and no current  information with respect to the cost of those securities
has been published, in which case the securities were valued at market. Further,
in  determining  such  aggregate  amount,   the  Transferee  may  have  included
securities   owned  by  subsidiaries  of  the  Transferee,   but  only  if  such
subsidiaries  are consolidated  with the Transferee in its financial  statements
prepared in accordance with generally accepted accounting  principles and if the
investments of such  subsidiaries are managed under the Transferee's  direction.
However,   such   securities   were  not  included  if  the   Transferee   is  a
majority-owned, consolidated subsidiary of another enterprise and the Transferee
is not itself a reporting company under the Securities Exchange Act of 1934.

     5. The  Transferee  acknowledges  that it is  familiar  with  Rule 144A and
understands that the Transferor and other parties related to the Certificate are
relying and will continue to rely on the  statements  made herein because one or
more sales to the Transferee may be in reliance on Rule 144A.

        ___       ___     Will the Transferee be purchasing the Certificate only
        Yes       No      for the Transferee's own account?

     6. If the answer to the foregoing question is "no," then in each case where
the  Transferee  is  purchasing  for an account other than its own, such account
belongs to a third party that is itself a "qualified institutional buyer" within
the meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been  established by the  Transferee  through one or more of the
appropriate methods contemplated by Rule 144A.

Master Servicer that (a) such transfer is permissible under applicable law, will
not constitute or result in any non-exempt prohibited  transaction under Section
406 of ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement and the Transferee has attached hereto an opinion of counsel to
such  affect,  or (b)  such  transfer  will  not  constitute  or  result  in any
non-exempt prohibited  transaction under ERISA or Section 4975 of the Code, will
not subject the Depositor,  the Trustee or the Master Servicer to any obligation
in addition to those undertaken in the Agreement,  and the following  conditions
are met:  (i) the  source  of  funds  used to  purchase  the  Certificate  is an
"insurance  company  general  account" (as such term is defined in United States
Department of Labor  Prohibited  Transaction  Class Exemption ("PTCE 95-60") and
(ii) the  conditions  set forth in  Sections  I and III of PTCE  95-60 have been
satisfied as of the date of the acquisition of the Certificate.

                                                          ANNEX 2 TO EXHIBIT B-2

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [For Transferees That Are Registered Investment Companies]

     The undersigned  hereby  certifies as follows to [name of Transferor]  (the
"Transferor")  and [name of Certificate  Registrar],  as Certificate  Registrar,
with  respect  to the  mortgage  pass-through  certificate  (the  "Certificate")
described in the Transferee  Certificate to which this certification relates and
to which this certification is an Annex:

     1. As indicated  below, the undersigned is the chief financial  officer,  a
person  fulfilling an equivalent  function,  or other  executive  officer of the
entity purchasing the Certificate (the  "Transferee") or, if the Transferee is a
"qualified  institutional  buyer" as that term is defined in Rule 144A under the
Securities  Act of 1933 ("Rule 144A") because the Transferee is part of a Family
of  Investment  Companies  (as defined  below),  is an executive  officer of the
investment adviser (the "Adviser").

     2. The Transferee is a "qualified  institutional  buyer" as defined in Rule
144A because (i) the Transferee is an investment  company  registered  under the
Investment  Company Act of 1940, and (ii) as marked below,  the Transferee alone
owned and/or invested on a discretionary  basis, or the  Transferee's  Family of
Investment  Companies owned, at least $100,000,000 in securities (other than the
excluded  securities  referred to below) as of the end of the Transferee's  most
recent fiscal year. For purposes of determining  the amount of securities  owned
by the Transferee or the Transferee's Family of Investment  Companies,  the cost
of such  securities  was  used,  unless  the  Transferee  or any  member  of the
Transferee's  Family of Investment  Companies,  as the case may be,  reports its
securities  holdings in its  financial  statements  on the basis of their market
value,  and no current  information with respect to the cost of those securities
has been  published,  in which case the securities of such entity were valued at
market.

     __  The  Transferee   owned  and/or  invested  on  a  discretionary   basis
     $___________ in securities (other than the excluded  securities referred to
     below) as of the end of the  Transferee's  most  recent  fiscal  year (such
     amount being calculated in accordance with Rule 144A).

     __ The Transferee is part of a Family of Investment  Companies  which owned
     in the  aggregate  $ in  securities  (other  than the  excluded  securities
     referred to below) as of the end of the  Transferee's  most  recent  fiscal
     year (such amount being calculated in accordance with Rule 144A).

     3. The term "Family of  Investment  Companies"  as used herein means two or
more  registered  investment  companies  (or series  thereof) that have the same
investment  adviser or  investment  advisers that are  affiliated  (by virtue of
being majority owned  subsidiaries  of the same parent or because one investment
adviser is a majority owned subsidiary of the other).

     4. The term  "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee or are part of the  Transferee's
Family of  Investment  Companies,  (ii) bank deposit notes and  certificates  of
deposit, (iii) loan participation,  (iv) repurchase  agreements,  (v) securities
owned but subject to a repurchase agreement and (vi) currency, interest rate and
commodity  swaps. For purposes of determining the aggregate amount of securities
owned and/or  invested on a discretionary  basis by the Transferee,  or owned by
the Transferee's Family of Investment  Companies,  the securities referred to in
this paragraph were excluded.

     5. The  Transferee  is  familiar  with Rule 144A and  understands  that the
parties to which this  certification is being made are relying and will continue
to  rely  on the  statements  made  herein  because  one or  more  sales  to the
Transferee will be in reliance on Rule 144A.

        ___       ___         Will the Transferee be purchasing the Certificate
        Yes       No          only for the Transferee's own account?


 
                                      B-2-7

<PAGE>


     6. If the answer to the foregoing question is "no," then in each case where
the  Transferee  is  purchasing  for an account other than its own, such account
belongs to a third party that is itself a "qualified institutional buyer" within
the meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been  established by the  Transferee  through one or more of the
appropriate methods contemplated by Rule 144A.

     7. The undersigned  will notify the parties to which this  certification is
made of any  changes  in the  information  and  conclusions  herein.  Until such
notice,  the  Transferee's   purchase  of  the  Certificate  will  constitute  a
reaffirmation  of this  certification  by the undersigned as of the date of such
purchase.

(the  "Certificate"),  pursuant to Section  5.02 of the  Pooling  and  Servicing

     1. The  Transferee  is acquiring  the  Certificate  for its own account for
investment and not with a view to or for sale or transfer in connection with any
distribution thereof, in whole or in part, in any manner which would violate the
Securities  Act of 1933, as amended (the  "Securities  Act"),  or any applicable
state securities laws.

     2. The Transferee  understands  that (a) the  Certificate  has not been and
will not be registered under the Securities Act or registered or qualified under
any applicable  state securities laws, (b) neither the Depositor nor the Trustee
is  obligated  so to  register or qualify  the  Certificate  and (c) neither the
Certificate nor any security issued in exchange  therefor or in lieu thereof may
be resold or transferred unless it is (i) registered  pursuant to the Securities
Act and registered or qualified pursuant to any applicable state securities laws
or  (ii)  sold or  transferred  in a  transaction  which  is  exempt  from  such
registration and qualification and the Certificate  Registrar has received (A) a
certificate from the prospective  transferor  substantially in the form attached
as Exhibit B-1 to the Pooling and Servicing  Agreement,  and a certificate  from
the prospective transferee  substantially in the form attached either as Exhibit
B-2 or Exhibit B-3 to the Pooling and Servicing Agreement,  or (B) an Opinion of
Counsel satisfactory to the Certificate  Registrar that the transfer may be made
without  registration  under  the  Securities  Act,  together  with the  written
certification(s)  as to the facts  surrounding the transfer from the prospective
transferor and/or  prospective  transferee upon which such Opinion of Counsel is
based.

     3. The Transferee  understands  that it may not sell or otherwise  transfer
the Certificate,  any security issued in exchange therefor or in lieu thereof or
any  interest in the  foregoing  except in  compliance  with the  provisions  of

OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR QUALIFICATION

QUALIFICATION  AND IN  ACCORDANCE  WITH THE  PROVISIONS  OF SECTION  5.02 OF THE
POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SERVICING AGREEMENT.

     4. Neither the  Transferee nor anyone acting on its behalf has (a) offered,
pledged,  sold,  disposed  of or  otherwise  transferred  the  Certificate,  any
interest in the  Certificate or any other similar  security to any person in any
manner, (b) solicited any offer to buy or accept a pledge,  disposition or other
transfer  of the  Certificate,  any  interest  in the  Certificate  or any other

taken  any  other  action,  that (in the case of any of the  acts  described  in
clauses  (a)  through  (e)  above)  would   constitute  a  distribution  of  the
Certificate  under the  Securities  Act,  would  render the  disposition  of the
Certificate  a  violation  of  Section  5 of the  Securities  Act  or any  state
securities law or would require registration or qualification of the Certificate
pursuant thereto.  The Transferee will not act, nor has it authorized or will it
authorize any person to act, in any manner set forth in the  foregoing  sentence

such knowledge and experience in financial and business matters as to be capable

Transferee has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision; and the Transferee is able to
bear the economic  risks of such an investment and can afford a complete loss of
such investment.

     7. The Transferee  hereby  certifies to the Trustee,  the Depositor and the
Master Servicer that (a) such transfer is permissible under applicable law, will
not constitute or result in any non-exempt prohibited  transaction under Section
406 of ERISA or Section 4975 of the Code and will not subject the Depositor, the
Trustee or the Master Servicer to any obligation in addition to those undertaken
in the Agreement and the Transferee has attached hereto an opinion of counsel to
such  affect,  or (b)  such  transfer  will  not  constitute  or  result  in any
non-exempt prohibited  transaction under ERISA or Section 4975 of the Code, will
not subject the Depositor,  the Trustee or the Master Servicer to any obligation
in addition to those undertaken in the Agreement,  and the following  conditions
are met:  (i) the  source  of  funds  used to  purchase  the  Certificate  is an
"insurance  company  general  account" (as such term is defined in United States

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT
                  FOR TRANSFERS OF REMIC RESIDUAL CERTIFICATES


STATE OF      )
              ) ss:
COUNTY OF     )


     _____________________, being first duly sworn, deposes and says that:

     1.  He/She  is  the   ____________________  of  ____________________   (the
prospective   transferee  (the   "Transferee")   of  GMAC  Commercial   Mortgage
Securities,  Inc., Mortgage  Pass-Through  Certificates,  Series 1998-C1,  Class
[R-I] [R-II] [R-III],  evidencing a ____% Percentage Interest in such Class (the
"Residual Certificates"), a ________________ duly organized and validly existing
under the laws of  _____________________,  on behalf of which  he/she makes this
affidavit.  All  capitalized  terms used but not otherwise  defined herein shall
have the  respective  meanings set forth in the Pooling and Servicing  Agreement
pursuant  to which the  Residual  Certificates  were issued  (the  "Pooling  and
Servicing Agreement").

     2.  The  Transferee  (i) is,  and as of the  date of  transfer  will  be, a
"Permitted  Transferee" and will endeavor to remain a "Permitted Transferee" for
so long as it  holds  the  Residual  Certificates,  and  (ii) is  acquiring  the
Residual  Certificates  for  its  own  account  or for the  account  of  another
prospective  transferee from which it has received an affidavit in substantially
the same form as this  affidavit.  A "Permitted  Transferee" is any Person other
than a "disqualified  organization"  or a possession of the United States.  (For
this purpose, a "disqualified  organization" means an electing large partnership
under  section  775 of the Code,  the  United  States,  any  state or  political
subdivision  thereof,  any  agency or  instrumentality  of any of the  foregoing
(other than an  instrumentality,  all of the  activities of which are subject to
tax and,  except for the Federal Home Loan Mortgage  Corporation,  a majority of
whose board of directors is not selected by any such governmental entity) or any
foreign government,  international organization or any agency or instrumentality
of such foreign  government  or  organization,  any rural  electric or telephone
cooperative, or any organization (other than certain farmers' cooperatives) that
is generally exempt from federal income tax unless such  organization is subject
to the tax on unrelated business taxable income.

     3.  The  Transferee  is  aware  (i) of the tax that  would  be  imposed  on
transfers of the Residual Certificates to "disqualified organizations" under the
Code that applies to all transfers of the Residual Certificates;  (ii) that such
tax would be on the transferor  (or, with respect to transfers to electing large
partnerships,  on such  partnership)  or, if such  transfer  is through an agent
(which  Person  includes a broker,  nominee or  middleman)  for a  non-Permitted
Transferee,  on the agent;  (iii) that the Person  (other  than  transfers  with
respect to electing large  partnerships)  otherwise  liable for the tax shall be
relieved of liability for the tax if the transferee  furnishes to such Person an
affidavit  that the  transferee  is a Permitted  Transferee  and, at the time of
transfer,  such Person  does not have actual  knowledge  that the  affidavit  is
false; and (iv) that the Residual  Certificates  may be a "noneconomic  residual
interest" within the meaning of Treasury regulation Section 1.860E-1(c) and that
the transferor of a "noneconomic  residual  interest" will remain liable for any
taxes due with  respect  to the  income  on such  residual  interest,  unless no
significant  purpose of the transfer is to enable the  transferor  to impede the
assessment or collection of tax.

     4. The  Transferee is aware of the tax imposed on a  "pass-through  entity"
holding the Residual  Certificates if at any time during the taxable year of the
pass-through  entity a  non-Permitted  Transferee  is the  record  holder  of an
interest in such entity.  (For this purpose, a "pass-through  entity" includes a
regulated  investment  company,  a real estate  investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

     5. The Transferee is aware that the Certificate Registrar will not register
any  transfer  of  the  Residual  Certificates  by  the  Transferee  unless  the
Transferee's transferee, or such transferee's agent, delivers to the Certificate
Registrar,  among other things,  an affidavit and agreement in substantially the
same form as this affidavit and agreement.  The Transferee expressly agrees that
it will not  consummate  any such  transfer  if it  knows or  believes  that any
representation contained in such affidavit and agreement is false.

     6. The Transferee  consents to any additional  restrictions or arrangements
that shall be deemed necessary upon advice of counsel to constitute a reasonable
arrangement to ensure that the Residual Certificate will only be owned, directly
or indirectly, by a Permitted Transferee.

     7. The Transferee's taxpayer identification number is __________.

     8. The  Transferee  has reviewed the  provisions of Section  5.02(d) of the
Pooling and Servicing Agreement,  a description of which provisions is set forth
in the Residual  Certificates (in particular,  clause (ii)(A) of Section 5.02(d)
which authorizes the Trustee to deliver payments on the Residual  Certificate to
a Person other than the Transferee  and clause (ii)(B) of Section  5.02(d) which
authorizes   the  Trustee  to  negotiate  a  mandatory   sale  of  the  Residual
Certificates,  in either  case,  in the event  that the  Transferee  holds  such
Residual  Certificates  in violation  of Section  5.02(d));  and the  Transferee
expressly agrees to be bound by and to comply with such provisions.

     9. No purpose of the Transferee relating to its purchase or any sale of the
Residual  Certificates  is or will be to impede the  assessment or collection of
any tax.

     10.  The  Transferee  hereby  represents  to and  for  the  benefit  of the
transferor that the Transferee  intends to pay any taxes associated with holding
the Residual  Certificates as they become due, fully  understanding  that it may
incur tax  liabilities  in excess of any cash flows  generated  by the  Residual
Certificates.

     11. The Transferee  will, in connection  with any transfer that it makes of
the Residual Certificates, deliver to the Certificate Registrar a representation
letter  substantially  in the form of Exhibit H-2 to the  Pooling and  Servicing
Agreement in which it will represent and warrant, among other things, that it is
not  transferring  the  Residual   Certificates  to  impede  the  assessment  or
collection of any tax and that it has at the time of such  transfer  conducted a
reasonable  investigation of the financial  condition of the proposed transferee
as  contemplated  by  Treasury  regulation  Section  1.860E-1(c)(4)(i)  and  has
satisfied the requirements of such provision.

     12.  The  Transferee  is a citizen or  resident  of the  United  States,  a
corporation, a partnership or other entity created or organized in, or under the
laws of, the United States or any political  subdivision thereof (except, in the
case of a  partnership,  to the extent  provided  in Treasury  regulations  such
partnership  is not a U.S.  person),  or an estate or trust  whose  income  from
sources  without  the United  States is  includible  in gross  income for United
States federal income tax purposes regardless of its connection with the conduct
of a trade or business within the United States.

     13. The Transferee is not (A) an 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) a Person  who is  directly  or  indirectly
purchasing the Class Residual  Certificates or interest therein on behalf of, as
named  fiduciary  of, as  trustee  of,  or with  assets  of a Plan,  unless  the
prospective  transferee  provides  the  Trustee,  the Fiscal  Agent,  the Master
Servicer  and the  Depositor  with a  certification  of facts and an  Opinion of
Counsel which establish to the  satisfaction  of the Trustee,  the Fiscal Agent,
the Master  Servicer and the Depositor that such transfer is  permissible  under
applicable  law, will not  constitute or result in a violation of Section 406 of
ERISA or  Section  4975 of the Code and will  not  subject  the  Depositor,  the
Trustee,  the Fiscal Agent or the Master  Servicer to any obligation in addition
to those undertaken in the Pooling and Servicing Agreement.

     Re:       GMAC Commercial Mortgage Securities,  Inc., Mortgage Pass-Through
               Certificates, Series 1998-C1 (the "Certificates")


Dear Sirs:

     This  letter  is  delivered  to you in  connection  with  the  transfer  by
_________________ (the "Transferor") to ____________________  (the "Transferee")
of [Class R-I] [Class R-II] [Class R-III] Certificates evidencing a % Percentage
Interest  in  such  Class  (the  "Residual  Certificates").   The  Certificates,
including  the Residual  Certificates,  were issued  pursuant to the Pooling and
Servicing  Agreement,  dated  as of May 1,  1998  (the  "Pooling  and  Servicing
Agreement"), among GMAC Commercial Mortgage Securities, Inc., as Depositor, GMAC
Commercial  Mortgage  Corporation,  as Master  Servicer  and  Special  Servicer,
LaSalle  National Bank, as Trustee and ABN AMRO Bank N.V., as Fiscal Agent.  All
capitalized  terms  used  but  not  otherwise  defined  herein  shall  have  the
respective  meanings  set forth in the  Pooling  and  Servicing  Agreement.  The
Transferor  hereby  certifies,  represents  and warrants to you, as  Certificate
Registrar, that:

     1. No purpose of the  Transferor  relating to the  transfer of the Residual
Certificates  by the  Transferor  to the  Transferee is or will be to impede the
assessment or collection of any tax.

     2. The  Transferor  understands  that the Transferee has delivered to you a
Transfer  Affidavit  and  Agreement  in the form  attached  to the  Pooling  and
Servicing  Agreement.   The  Transferor  does  not  know  or  believe  that  any
representation contained therein is false.

     3. The Transferor  has at the time of this transfer  conducted a reasonable
investigation  of the financial  condition of the Transferee as  contemplated by
Treasury  regulation  Section   1.860E-1(c)(4)(i)  and,  as  a  result  of  that
investigation,   the  Transferor   has   determined   that  the  Transferee  has
historically  paid its debts as they  became  due and has  found no  significant
evidence to indicate that the  Transferee  will not continue to pay its debts as
they become due in the future.  The Transferor  understands that the transfer of
the Residual  Certificates  may not be respected  for United  States  income tax
purposes (and the  Transferor may continue to be liable for United States income
taxes  associated  therewith)  unless  the  Transferor  has  conducted  such  an
investigation.

     4. The Transferee has no actual knowledge that such prospective  Transferee
is not a Permitted Transferee or is not a United States Person.

                                             Very truly yours,

     Methodology to Normalize Net Operating Income and Debt Service Coverage


o    GMAC Commercial  Mortgage  Corporation  ("GMACCM")  applies the methodology
     presented  below to arrive  at a  servicer  adjusted  or  "Normalized"  Net
     Operating  Income ("NOI").  The items described below highlight some of the
     major categories requiring  adjustment.  There may, however, be others, and
     GMACCM  will  use  its  market  knowledge  and  discretion  in  making  and
     sufficiently footnoting the necessary adjustments.

o    GMACCM  chooses to use the actual  management  fee stated in the  financial
     statement.

o    Where they are clearly identifiable, GMACCM will remove any capital expense
     from any above  the line  categories  (such as  extraordinary  repairs  and
     maintenance)  and put them below the line in the  capital  expense  comment
     section.

o    Replacement  reserves,  tenant improvement and leasing commission  reserves
     will be treated as above the line expenses.  A  determination  will be made
     whether  there have been credits for the  disbursements  from a reserve and
     that expenses are not overstated due to exclusion of credits.

o    Property  taxes should be the annual amount due,  excluding any  delinquent
     taxes or credits from prior years which would cause the number to be higher
     or lower.  The amount for  property  taxes will be  adjusted  if the period
     under analysis is less than one year.

o    GMAC Commercial Mortgage will exclude non-recurring,  extraordinary income.
     For example,  a tax refund,  lease  buyout or income  received for a period
     other than the year in question should be adjusted.  If past due rent for a
     prior year was paid and recorded in the current year,  GMACCM would back it
     out  and  footnote  it  accordingly.  Care  will be  used  when  reflecting
     percentage/overage  rents to  ensure  that it  relates  to the  appropriate
     period and that the numbers are supported by tenant sales information.

o    GMAC  Commercial  Mortgage  will  remove  any items not  pertaining  to the
     operation of the property such as, fees for closing the loan restructure, a
     distribution to owners or a charitable contribution.

o    When  necessary,  income  and  expenses  will be  analyzed  by  looking  at
     variances by category. Unusual income and expense items will be researched.
     If there are significant variances, inquiries to the borrower will be made.
     Appropriate  adjustments  will be made and  footnotes  provided  to clearly
     explain the situation.

o    The debt  service  should be an actual  amount  the  borrower  paid per the
     servicing records for the period  associated with the operating  statement.
     If GMACCM does not have a full year of payments,  it will use the principal
     and interest  constant in the case of a fixed rate loan and, in the case of
     an adjustable  rate loan, will estimate a full year amount from the payment
     history information available.

                                                                  EXECUTION COPY

                        MORTGAGE LOAN PURCHASE AGREEMENT

     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of April 28, 1998, between GMAC Commercial Mortgage  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 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 May 1, 1998 (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 National Bank 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.

     The  Purchaser  intends to sell  certain of the  Certificates  to  Deutsche
Morgan Grenfell Inc.,  Lehman Brothers Inc. and Residential  Funding  Securities
Corp. (together, the "Underwriters") pursuant to an underwriting agreement dated
the date hereof (the  "Underwriting  Agreement").  The Purchaser intends to sell
the  remaining  Certificates  (the  "Non-Registered  Certificates")  to Deutsche
Morgan  Grenfell  Inc. and Lehman  Brothers  Inc.  (the  "Initial  Purchasers"),
pursuant  to a  certificate  purchase  agreement  dated  the  date  hereof  (the
"Certificate Purchase Agreement").

     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 18, 1998 or such
other date as shall be mutually  acceptable to the parties  hereto (the "Closing
Date").  As of the close of business on May 1, 1998 (the  "Cut-off  Date"),  the
Mortgage Loans will have an aggregate  principal balance (the "Aggregate Cut-off
Date Balance"), after application of all payments of principal due thereon on or
before  such date,  whether or not  received,  of  $1,198,282,763,  subject to a
variance of plus or minus 5%. The purchase price for the Mortgage Loans shall be
determined and paid to the Seller in accordance  with the terms of an allocation
agreement  dated the date  hereof  (the  "Allocation  Agreement"),  to which the
Seller and Purchaser, among others, are parties.

     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 in accordance with the Allocation
Agreement),  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, 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,  and all other  recoveries  of
principal and interest  collected  thereon after the Cut-off Date. All scheduled
payments of principal and interest due thereon on or before the Cut-off Date and
collected after the 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
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

                                       2

included in the related Mortgage File,  provided that a copy of such document or
instrument  (without  evidence of recording  or filing  thereon,  but  certified
(which certificate may relate to multiple  documents and/or  instruments) by the
Seller to be a true and complete  copy of the  original  thereof  submitted  for
recording or filing, as the case may be) has been delivered to the Trustee,  and
either the original of such missing  document or instrument,  or a copy thereof,
with evidence of recording or filing, as the case may be, thereon,  is delivered
to or at the direction of the Purchaser (or any subsequent owner of the affected
Mortgage Loan,  including without limitation the Trustee) within 180 days of the
Closing  Date (or  within  such  longer  period  after the  Closing  Date as the
Purchaser (or such subsequent  owner) may consent to, which consent shall not be
unreasonably  withheld so long as the Seller has provided the Purchaser (or such
subsequent owner) with evidence of such recording or filing, as the case may be,
or  has  certified  to  the  Purchaser  (or  such  subsequent  owner)  as to the
occurrence of such recording or filing, as the case may be, and is, as certified
to the Purchaser (or such  subsequent  owner) no less often than  quarterly,  in
good faith attempting to obtain from the appropriate county recorder's or filing
office such  original or copy).  If the Seller  cannot  deliver,  or cause to be
delivered,  as to any  Mortgage  Loan,  the  original  or a copy of the  related
lender's title  insurance  policy referred to in clause (ix) of Exhibit B solely
because such policy has not yet been issued,  the delivery  requirements of this
Section 2(b) shall be deemed to be satisfied as to such missing  item,  and such
missing item shall be deemed to have been included in the related Mortgage File,
provided  that the Seller has  delivered to the Trustee a  commitment  for title
insurance "marked-up" at the closing of such Mortgage Loan, and the Seller shall
deliver to or at the direction of the Purchaser (or any subsequent  owner of the
affected  Mortgage Loan,  including  without  limitation the Trustee),  promptly
following the receipt  thereof,  the original  related  lender's title insurance
policy  (or a  copy  thereof).  In  addition,  notwithstanding  anything  to the
contrary  contained herein, if there exists with respect to any group of related
cross-collateralized  Mortgage Loans only one original of any document  referred
to in  Exhibit  B  covering  all the  Mortgage  Loans  in such  group,  then the
inclusion of the original of such  document in the Mortgage  File for any of the
Mortgage  Loans in such group shall be deemed an inclusion  of such  original in
the  Mortgage  File for each such  Mortgage  Loan.  On the  Closing  Date,  upon
notification  from the Seller that the purchase  price  referred to in Section 1
(exclusive of any  applicable  holdback for  transaction  expenses in accordance
with the  Allocation  Agreement)  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 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; 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

                                       3

<PAGE>


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.

                                       4

<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 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,  

                                       5

<PAGE>


     any security  evidencing  or, upon  issuance,  that would have evidenced an
     interest in the Mortgage Loans or any substantial number thereof.

          (ix) Insofar as it relates to the Mortgage Loans,  the information set
     forth on pages A-9 through A-13,  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/or the Seller and does not represent a  restatement  or
     aggregation of the  information  on the Loan Detail,  the  information  set
     forth in the Prospectus  Supplement and the Memorandum  (also as defined in
     Section 9) under the headings  "Summary of the  Prospectus  Supplement--The
     Mortgage Asset Pool", "Risk  Factors--The  Mortgage Loans" and "Description
     of the  Mortgage  Asset  Pool",  set  forth  on  Annex A to the  Prospectus
     Supplement and (to the extent it contains information  consistent with that
     on such Annex A) set forth on the  Diskette,  does not  contain  any untrue
     statement of a material fact or (in the case of the  Memorandum,  when read
     together with the other  information  specified  therein as being available
     for review by investors)  omit to state any material fact necessary to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading.

          (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.

                                       6

<PAGE>


          (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  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.

                                       7

<PAGE>


     (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)  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, 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)  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.

     If the Seller is notified of a defect in any Mortgage File that corresponds
to  information  set forth in the  Mortgage  Loan  Schedule,  the  Seller  shall
promptly correct such defect and provide a new, corrected Mortgage Loan Schedule
to the  Purchaser,  which  corrected  Mortgage Loan Schedule  shall be deemed to
amend and replace the existing Mortgage Loan Schedule for all purposes.

     (b)  Notwithstanding  Section  6(a),  within  60  days  of the  earlier  of
discovery or receipt of notice by the Seller,  from either the  Purchaser or any
successor  or assign  thereof,  that any  Mortgage  Loan does not  constitute  a
"qualified  mortgage" within the meaning of Section  860G(a)(3) of the Code, the
Seller shall repurchase such Mortgage Loan from the then owner(s) thereof at the
applicable  Purchase Price by payment of such Purchase Price by wire transfer of
immediately available funds to the account designated by such owner(s).

     In addition,  if, as of the Closing Date, any Mortgage Loan is secured by a
Mortgage that does not constitute a valid first lien upon the related  Mortgaged
Property,  including all  buildings  located  thereon and all fixtures  attached
thereto,  or if a Mortgage  is subject to  something  other than (A) the lien of
current  real  property  taxes  and  assessments  not yet due and  payable,  (B)
covenants,  conditions  and  restrictions,  rights of way,  easements  and other
matters of public record, (C) exceptions and exclusions specifically referred to
in the lender's title insurance  policy issued or, as evidenced by a "marked-up"
commitment,  to be  issued  in  respect  of such  Mortgage  Loan  and (D)  those
exceptions  set forth on Schedule  C-1 to Exhibit C hereto (the  exceptions  set
forth in the foregoing  clauses (A), (B), (C) and (D)  collectively,  "Permitted
Encumbrances"),  or if the insurer that issued the Title  Policy  referred to in
clause  (vi) of  Exhibit  C  hereto  in  respect  of any  Mortgage  Loan was not
qualified to do business in the state in which the related Mortgaged Property is
located,  and in either case such failure  materially and adversely  affects the
interests  of holder of  Certificates,  (any such failure  that  materially  and
adversely  affects the  interests of holders of  Certificates,  also a "Material
Breach"),  the Seller shall be required,  at its option, to either (i) cure such
Material  Breach  in all  material  respects  or (ii)  repurchase  the  affected
Mortgage Loan, in each case, within the applicable Permitted Cure Period. If any
such Material Breach

                                       8

<PAGE>


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 foregoing,  and subject to the following paragraph, the
"Permitted  Cure Period"  applicable to any Defect or Material Breach in respect
of any  Mortgage  Loan  shall be the 90-day  period  immediately  following  the
earlier  of the  discovery  by the  Seller or receipt by the Seller of notice of
such Defect or Material Breach, as the case may be; provided that if such Defect
or Material  Breach,  as the case may be,  cannot be  corrected  or cured in all
material respects within such 90-day period,  but is reasonably likely that such
Defect or  Material  Breach,  as the case may be,  could be  corrected  or cured
within 180 days of the  earlier of  discovery  by the Seller and  receipt by the
Seller of notice of such Material  Documents Defect or Material  Breach,  as the
case may be, and the Seller is diligently  attempting to effect such  correction
or cure,  then the applicable  Permitted Cure Period shall,  with the consent of
the  Purchaser  or  its  assignee  (which  consent  shall  not  be  unreasonably
withheld), be extended for an additional 90 days.

     (c) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan  contemplated by this Section 6, the then owner(s)  thereof shall tender or
cause to be tendered promptly to the Seller, upon delivery of a receipt executed
by the Seller,  the related  Mortgage File and Servicing File, and each document
that  constitutes  a part of the Mortgage  File that was endorsed or assigned to
the Purchaser or the Trustee shall be endorsed or assigned,  as the case may be,
to the  Seller  in the  same  manner.  The  form  and  sufficiency  of all  such
instruments and certificates shall be the responsibility of the Seller.

     (d) Except as provided in Section  2(b),  this  Section 6 provides the sole
remedies available to the Purchaser,  and its successors and assigns (including,
without limitation,  the Trustee and the holders of the Certificates) respecting
any Defect in a Mortgage  File or any breach of any  representation  or warranty
made pursuant to Section 4(a) and set forth in Exhibit C, or in connection  with
the  circumstances  described  in Section  6(b).  If the Seller  defaults on its
obligations to repurchase  any Mortgage Loan in accordance  with Section 6(a) or
6(b) or disputes its  obligation to  repurchase  any Mortgage Loan in accordance
with either such  subsection,  the Purchaser or its  successors  and assigns may
take such  action as is  appropriate  to enforce  such  payment or  performance,
including,  without  limitation,  the institution and prosecution of appropriate
proceedings.  The Seller shall  reimburse  the  Purchaser  for all necessary and
reasonable costs and expenses incurred in connection with such enforcement.

     SECTION 7. Closing.

     The closing of the sale of the Mortgage Loans (the "Closing") shall be held
at the offices of Orrick,  Herrington  & Sutcliffe  LLP, 666 Fifth  Avenue,  New
York, New York 10103 at 10:00 a.m., New York City time, on the Closing Date.

                                       9

<PAGE>


     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  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

     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.

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  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  contained  in  the  Prospectus
Supplement  or  the  Memorandum  under  the  headings   "Summary  of  Prospectus
Supplement  - The  Mortgage  Asset Pool",  "Risk  Factors - The Mortgage  Loans"
and/or  "Description  of the Mortgage Asset Pool" or contained on Annex A to the
Prospectus  Supplement (exclusive of the Loan Detail), and such information does
not represent a restatement or aggregation 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

                                       11

<PAGE>


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.  333-37717  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 December 17,
1997, as  supplemented  by the prospectus  supplement  dated April 28, 1998 (the
"Prospectus Supplement"), relating to the Registered Certificates;  "Memorandum"
shall mean the private  placement  memorandum dated April 28, 1998,  relating to
the  Non-Registered  Certificates;  "Computational  Materials"  shall  have  the
meaning  assigned  thereto in the no-action  letter dated May 20, 1994 issued by
the Division of Corporation  Finance of the  Securities and Exchange  Commission
(the "Commission") to Kidder,  Peabody Acceptance Corporation I, Kidder, Peabody
& Co.  Incorporated,  and Kidder  Structured Asset Corporation and the no-action
letter dated May 27, 1994 issued by the Division of  Corporation  Finance of the
Commission  to  the  Public  Securities  Association   (together,   the  "Kidder
Letters");  and "ABS Term Sheets" shall have the meaning assigned thereto in the
no-action  letter dated  February 17, 1995 issued by the Division of Corporation
Finance of the Commission to the Public Securities Association (the "PSA Letter"
and, together with the Kidder Letters, the "No-Action Letters").

     (b) Promptly after receipt by any person entitled to indemnification  under
this Section 9 (each, an "indemnified  party") of notice of the  commencement of
any action,  such indemnified party will, if a claim in respect thereof is to be
made against the Seller (the "indemnifying  party") under this Section 9, notify
the indemnifying party in writing of the commencement  thereof; but the omission
to notify the indemnifying  party will not relieve it from any liability that it
may have to any  indemnified  party otherwise than under this Section 9. In case
any such action is brought  against any  indemnified  party and it notifies  the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to participate  therein, and to the extent that it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof,  with counsel
satisfactory  to  such  indemnified  party;  provided,   however,  that  if  the
defendants  in any such  action  include  both  the  indemnified  party  and the
indemnifying  party and the  indemnified  party or parties shall have reasonably
concluded that there may be legal defenses  available to it or them and/or other
indemnified  parties that are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select  separate  counsel  to  assert  such  legal  defenses  and  to  otherwise
participate in the defense of such action on behalf of such indemnified party or
parties.  Upon receipt of notice from the indemnifying party to such indemnified
party of its  election to assume the defense of such action and  approval by the
indemnified party of counsel,  which approval will not be unreasonably withheld,
the  indemnifying  party  will not be  liable  for any  legal or other  expenses
subsequently  incurred by such indemnified  party in connection with the defense
thereof,  unless (i) the indemnified  party shall have employed separate counsel
in  connection  with the  assertion  of legal  defenses in  accordance  with the
proviso  to the  preceding  sentence  (it being  understood,  however,  that the
indemnifying  party  shall  not be  liable  for the  expenses  of more  than one
separate  counsel,  approved  by  the  Purchaser  and  the  indemnifying  party,
representing  all the indemnified  parties under Section 9(a) who are parties to
such  action),  (ii) the  indemnifying  party  shall not have  employed  counsel
reasonably  satisfactory to the  indemnified  party to represent the indemnified
party within a reasonable  time after  notice of  commencement  of the action or
(iii) the  indemnifying  party has  authorized the employment of counsel for the
indemnified party at the expense of the indemnifying  party;

                                       12

<PAGE>


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  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 in accordance with the Allocation Agreement.

     SECTION 11. Notices.

     All demands,  notices and communications  hereunder shall be in writing and
shall be deemed to have been duly given if personally delivered to or mailed, by

     Each of the officers,  directors  and  controlling  persons  referred to in
Section 9 hereof is an intended  third party  beneficiary  of the  covenants and
indemnities  of the  Seller  set  forth in  Section 9 of this  Agreement.  It is
acknowledged  and agreed that such covenants and  indemnities may be enforced by
or on behalf of any such person or entity  against the Seller to the same extent
as if it was a party hereto.

     SECTION 13. Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,
incorporated herein by reference or contained in the certificates of officers of
the Seller submitted  pursuant hereto,  shall remain operative and in full force
and effect and shall survive delivery of the Mortgage Loans by the Seller to the
Purchaser or its designee.

     SECTION 14. Severability of Provisions.

     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 15. 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.

except that any person into which the Seller may be merged or  consolidated,  or
any  corporation  or other  entity  resulting  from any  merger,  conversion  or
consolidation to which the Seller is a party, or any person succeeding to all or
substantially  all of the business of the Seller,  shall be the successor to the
Seller hereunder.  The Purchaser has the right to assign its interest under this
Agreement, in whole or in part, as may be required to effect the purposes of the
Pooling and Servicing  Agreement,  and the assignee shall, to the extent of such

                                    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, 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,  to the  extent  such  security  interest  can be
perfected  by the  recordation  of a Mortgage  or the filing of a UCC  financing
statement,  in all personal property owned by the Mortgagor that is used in, and
is reasonably necessary to, the operation of the related Mortgaged Property.

     (vi) Title  Insurance.  The lien of the  related  Mortgage is insured by an
ALTA lender's  title  insurance  policy ("Title  Policy"),  or its equivalent as
adopted in the applicable jurisdiction,  issued by a nationally recognized title
insurance company, insuring the originator of such Mortgage Loan, its successors
and  assigns,  as to the first  priority  lien of the  Mortgage in the  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

                                      C-1

<PAGE>


foregoing   description  is  evidenced  by  a  commitment  for  title  insurance
"marked-up"  at the closing of such loan).  Each Title Policy (or, if it has yet
to be issued,  the coverage to be provided thereby) is in full force and effect,
all premiums thereon have been paid and, to the Seller's knowledge,  no material
claims have been made  thereunder and no claims have been paid  thereunder.  The
Seller has not, by act or omission,  done anything that would materially  impair
the coverage  under such Title  Policy.  Immediately  following the transfer and
assignment of the related  Mortgage Loan to the Trustee,  such Title Policy (or,
if it has yet to be issued,  the coverage to be provided  thereby) will inure to
the benefit of the Trustee without the consent of or notice to the insurer.

     (vii) No Waivers by Seller of Material Defaults.  The Seller has not waived
any material default,  breach, violation or event of acceleration existing under
the related Mortgage or Mortgage Note.

     (viii) No Offsets,  Defenses or  Counterclaims.  There is no valid  offset,
defense or counterclaim to such Mortgage Loan.

     (ix)  Condition  of  Property;  Condemnation.  Except  as set  forth in any
engineering  report  prepared in connection with the origination of (or obtained
in  connection  with or otherwise  following the Seller's  acquisition  of) such
Mortgage Loan,  the related  Mortgaged  Property is, to the Seller's  knowledge,
free and clear of any damage  that would  materially  and  adversely  affect its
value as security for such Mortgage Loan. The Seller has no actual notice of the
commencement of a proceeding for the condemnation of all or any material portion
of the related Mortgaged Property.

     (x)  Compliance  with Usury Laws.  Such  Mortgage  Loan  complied  with all
applicable usury laws in effect at its date of origination.

     (xi) Full  Disbursement  of Mortgage  Loan  Proceeds.  The proceeds of such
Mortgage Loan have been fully  disbursed and there is no requirement  for future
advances thereunder.

     (xii) Enforceability.  The related Mortgage Note and Mortgage and all other
documents  and  instruments  evidencing,  guaranteeing,  insuring  or  otherwise
securing such Mortgage Loan have been duly and properly  executed by the parties
thereto,  and each is the  legal,  valid  and  binding  obligation  of the maker
thereof  (subject  to  any  non-recourse  provisions  contained  in  any  of the
foregoing  agreements and any  applicable  state  anti-deficiency  legislation),
enforceable  in accordance  with its terms,  except as such  enforcement  may be
limited by bankruptcy, insolvency,  reorganization,  receivership, moratorium or
other laws  relating to or affecting  the rights of creditors  generally  and by
general  principles  of  equity  (regardless  of  whether  such  enforcement  is
considered in a proceeding in equity or at law).

     (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   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 

                                      C-2

<PAGE>


available, a flood insurance policy meeting any requirements of the then current
guidelines of the Federal Insurance Administration is in effect with a generally
acceptable  insurance carrier, in an amount representing  coverage not less than
the least of (1) the  outstanding  principal  balance of such Mortgage Loan, (2)
the full insurable value of such Mortgaged  Property,  (3) the maximum amount of
insurance  available under the National Flood Insurance Act of 1968, as amended,
and  (4)  100%  of the  replacement  cost of the  improvements  located  on such
Mortgaged Property. In addition, the Mortgage requires the Mortgagor to maintain
in respect of the Mortgaged Property  comprehensive  general liability insurance
in amounts generally  required by the Seller,  and at least six months rental or
business interruption insurance, and all such insurance required by the Mortgage
to be  maintained  is in full  force  and  effect.  Each such  insurance  policy
requires  prior  notice  to  the  holder  of  the  Mortgage  of  termination  or
cancellation,  and no such  notice has been  received,  including  any notice of
nonpayment of premiums, that has not been cured.

     (xiv) Environmental  Condition.  The related Mortgaged Property was subject
to one or more  environmental  site  assessments  (or an update of a  previously
conducted assessment), which was (were) performed on behalf of the Seller, or as
to which the related  report was delivered to the Seller in connection  with its
origination or acquisition of such Mortgage Loan; and the Seller, having made no
independent   inquiry  other  than  reviewing  the  resulting  report(s)  and/or
employing an environmental  consultant to perform the  assessment(s)  referenced
herein, has no knowledge of any material and adverse environmental conditions or
circumstance  affecting  such  Mortgaged  Property that was not disclosed in the
related  report(s).  The Seller has not taken any  action  with  respect to such
Mortgage  Loan  or  the  related  Mortgaged  Property  that  could  subject  the
Purchaser, or its successors and assigns in respect of the Mortgage Loan, to any
liability  under the  Comprehensive  Environmental  Response,  Compensation  and
Liability Act of 1980, as amended  ("CERCLA") or any other  applicable  federal,
state or local  environmental  law,  and the Seller has not  received any actual
notice of a material  violation of CERCLA or any  applicable  federal,  state or
local  environmental law with respect to the related Mortgaged Property that was
not disclosed in the related report.  The related  Mortgage or loan documents in
the related  Mortgage File requires the Mortgagor to comply with all  applicable
federal, state and local environmental laws and regulations.

     (xv) No  Cross-Collateralization  with Other Mortgage Loans.  Such Mortgage
Loan is not  cross-collateralized  with  any  mortgage  loan  that  will  not be
included in the Trust Fund.

     (xvi) Waivers and Modifications.  The terms of the related Mortgage and the
Mortgage  Note  have not been  impaired,  waived,  altered  or  modified  in any
material respect, except as specifically set forth in the related Mortgage File.

     (xvii) Taxes and Assessments.  There are no delinquent taxes, ground rents,
assessments for improvements or other similar  outstanding charges affecting the
related  Mortgaged  Property which are or may become a lien of priority equal to
or  higher  than  the  lien  of the  related  Mortgage.  For  purposes  of  this
representation  and warranty,  real property taxes and assessments  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
three  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

                                      C-3

<PAGE>


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.

     (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

                                      C-4

<PAGE>


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) [Reserved.]

     (xxvii) No Equity Participation or Contingent  Interest.  The Mortgage Loan
contains no equity  participation  by the  lender,  and does not provide for any
contingent or additional  interest in the form of participation in the cash flow
of the related Mortgaged Property, or for negative amortization.

     (xxviii) No Advances of Funds.  No holder of the Mortgage  Loan has, to the
Seller's knowledge,  advanced funds or induced,  solicited or knowingly received
any advance of funds from a party other than the owner of the related  Mortgaged
Property,  directly or indirectly, for the payment of any amount required by the
Mortgage Loan.

     (xxix)  Licenses,  Permits,  Etc. To the Seller's  knowledge,  based on due
diligence  customarily performed in the origination of comparable mortgage loans
by the Seller,  as of the date of  origination of the Mortgage Loan, the related
Mortgagor or operator of the related Mortgaged Property was in possession of all
material licenses,  permits and  authorizations  required by applicable laws for
the  ownership and  operation of the related  Mortgaged  Property as it was then
operated and if a related  Mortgaged  Property is improved by a skilled nursing,
congregate  care or assisted  living  facility,  the most recent  inspection  or
survey by governmental  authorities having  jurisdiction in connection with such
licenses,  permits and  authorizations  did not cite such Mortgaged Property for
material  violations  (which  shall  include  only  "Level  A"  (or  equivalent)
violations in the case of skilled nursing facilities) that had not been cured or
as to which a plan of correction  had not been submitted to and accepted by such
governmental  authorities.  To the extent such facility participates in Medicaid
or Medicare,  such facility is in  compliance in all material  respects with the
requirements of such program.

     (xxx) Servicing.  The servicing and collection  practices used with respect
to the Mortgage Loan have complied with applicable law in all material  respects
and are consistent  with the servicing  standard set forth in Section 3.01(a) of
the Pooling and Servicing Agreement.

     (xxxi) Customary Remedies.  The related Mortgage or Mortgage Note, together
with  applicable  state  law,  contains  customary  and  enforceable  provisions
(subject to the exceptions  set forth in paragraph  (xii)) such as to render the
rights  and  remedies  of  the  holders  thereof   adequate  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  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 each  Mortgage  Loan to the related
Mortgagor at origination did not exceed the  non-contingent  principal amount of
the Mortgage  Loan and either:  (A)

                                      C-5

<PAGE>


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)  Inspection.  In connection  with the  origination or acquisition of
each Mortgage Loan, the Seller inspected or caused to be inspected the Mortgaged
Property.

     (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 estate in real estate or, if the related Mortgage Loan is
secured in whole or in part by the  interest of a Mortgagor  as a lessee under a
ground  lease  of a  Mortgaged  Property  (a  "Ground  Lease"),  by the  related
Mortgagor's  interest in the Ground Lease but not by the related fee interest in
such Mortgaged  Property (the "Fee Interest") or if the Mortgage Loan is secured
in whole or in part by a Ground Lease and a Fee Interest,  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,  such  Ground  Lease or a
              memorandum thereof has been or will be duly recorded;  such Ground
              Lease  (or  the  related  estoppel  letter  or  lender  protection
              agreement  between  the Seller and  related  lessor)  permits  the
              interest of the lessee  thereunder to be encumbered by the related
              Mortgage;  and there has been no  material  change in the  payment
              terms of such Ground  Lease since the  origination  of the related
              Mortgage Loan, with the exception of material changes reflected in
              written instruments that are a part of the related Mortgage File;

                                      C-6

<PAGE>


       (b)    The  lessee's  interest in such Ground Lease is not subject to any
              liens or encumbrances  superior to, or of equal priority with, the
              related  Mortgage,  other than the  ground  lessor's  related  fee
              interest and Permitted Encumbrances;

       (c)    The Mortgagor's interest in such Ground Lease is assignable to the
              Purchaser  and its  successors  and  assigns  upon  notice to, but
              without the consent of, the lessor thereunder (or, if such consent
              is required,  it has been obtained prior to the Closing Date) and,
              in the event that it is so assigned,  is further assignable by the
              Purchaser  and its  successors  and  assigns  upon  notice to, but
              without the need to obtain the consent of, such lessor;

       (d)    Such Ground Lease is in full force and effect,  and the Seller has
              received  no  notice  that  an  event  of  default  has   occurred
              thereunder, and, to the Seller's actual knowledge, there exists no
              condition  that,  but for the  passage  of time or the  giving  of
              notice,  or both,  would  result in an event of default  under the
              terms of such Ground Lease;

       (e)    Such  Ground  Lease,  or an  estoppel  letter or other  agreement,
              requires  the lessor under such Ground Lease to give notice of any
              default  by  the  lessee  to  the  mortgagee,  provided  that  the
              mortgagee  has  provided  the  lessor  with  notice of its lien in
              accordance  with the  provisions  of such Ground  Lease,  and such
              Ground Lease,  or an estoppel letter or other  agreement,  further
              provides  that no notice of  termination  given  under such Ground
              Lease is effective  against the  mortgagee  unless a copy has been
              delivered to the mortgagee;

       (f)    A mortgagee  is  permitted a  reasonable  opportunity  (including,
              where  necessary,  sufficient  time  to  gain  possession  of  the
              interest  of the  lessee  under  such  Ground  Lease)  to cure any
              default  under  such  Ground  Lease,  which is  curable  after the
              receipt  of  notice  of  any  such  default,   before  the  lessor
              thereunder may terminate such Ground Lease;

       (g)    Such Ground Lease has an original  term  (including  any extension
              options set forth  therein)  which extends not less than ten years
              beyond the Stated Maturity Date of the related Mortgage Loan;

       (h)    Under the terms of such  Ground  Lease and the  related  Mortgage,
              taken  together,  any  related  insurance  proceeds  other than in
              respect of a total or substantially  total loss or taking, will be
              applied  either to the repair or restoration of all or part of the
              related  Mortgaged  Property,  with  the  mortgagee  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; and

       (i)    Such Ground Lease does not impose any  restrictions  on subletting
              which  would

                                      C-7

<PAGE>


              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.

       (j)    Such Ground Lease requires the lessor to enter into a new lease in
              the  event of a  termination  of the  Ground  Lease by reason of a
              default  by the  Mortgagor  under  the  Ground  Lease,  including,
              rejection of the ground lease in a bankruptcy proceeding.

     (xxxviii)  Deed of Trust.  If the related  Mortgage  is a deed of trust,  a
trustee,  duly  qualified  under  applicable  law to serve as such,  is properly
designated and serving under such Mortgage.

     (xxxix)  Lien  Releases.  Except in cases  where  either (a) a release of a
portion  of the  Mortgaged  Property  was  contemplated  at  origination  of the
Mortgage  Loan and such  portion was not  considered  material  for  purposes of
underwriting   the  Mortgage  Loan  or  (b)  release  is  conditioned  upon  the
satisfaction of certain underwriting and legal requirements and the payment of a
release price, the related Mortgage Note or Mortgage does not require the holder
thereof to release all or any portion of the Mortgaged Property from the lien of
the related  Mortgage  except upon payment in full of all amounts due under such
Mortgage Loan.

     (xl) Junior Liens. The Mortgage Loan does not permit the related  Mortgaged
Property to be  encumbered  by any lien junior to or of equal  priority with the
lien of the related  Mortgage  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. Except for those Mortgage Loans identified on
Schedule C-1 hereto which  represent 2.95% of the Mortgage Loans by Cut-Off Date
Principal Balance, the Mortgagor is an entity,  other than an individual,  whose
organizational   documents  or  the  related  Mortgage  Loan  Documents  provide
substantially  to the  effect  that the  Mortgagor:  (a) is formed or  organized
solely  for the  purpose of owning and  operating  one or more of the  Mortgaged
Properties  securing  the  Mortgage  Loans,  (b) may not engage in any  business
unrelated to such Mortgaged Property or Mortgaged Properties,  (c) does not have
any assets  other than those  related to its  interest in and

                                      C-8

<PAGE>


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) [Reserved.]

     (xlvi) 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,  1998),  (ii)  only  with  substitute
collateral  constituting  "government  securities"  within the meaning of Treas.
Reg. ss.  1.860G-2(a)(8)(i),  and (iii) only to facilitate  the  disposition  of
mortgage real property and not as a part of an  arrangement to  collateralize  a
REMIC offering with obligations that are not real estate mortgages.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Exhibit 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  without  limitation the
Trustee and the holders of the Certificates), notwithstanding any restrictive or
qualified endorsement or assignment.

                   FORM OF OPINION I OF COUNSEL TO THE SELLER


May [__], 1998


To: Persons on Annex A

Re: GMAC Commercial Mortgage Corporation,
    Mortgage Pass-Through Certificates, Series 1998-C1

Ladies and Gentlemen:

     I  am  General  Counsel  to  GMAC  Commercial  Mortgage   Corporation  (the
"Seller"). In that capacity, I am familiar with the issuance of certain Mortgage
Pass-Through  Certificates,  Series  1998-C1  (the  "Certificates"),  evidencing
undivided  interests in a trust fund (the "Trust Fund") consisting  primarily of
certain  mortgage  loans  (the  "Mortgage  Loans"),  pursuant  to a Pooling  and
Servicing  Agreement,  dated  as of May 1,  1998  (the  "Pooling  and  Servicing
Agreement"),  among GMAC Commercial Mortgage Securities, Inc. (the "Company") as
depositor, the Seller as master servicer and special servicer,  LaSalle National
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 April 28,  1998  (the  "GMACCM  Mortgage  Loan
Purchase  Agreement"),  between  the  Company  and the  Seller.  Certain  of the
Mortgage  Loans were  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 April 28, 1998 (the "GACC Mortgage
Loan  Purchase  Agreement"),  between  GACC and the  Company.  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 X, Class A-1,  Class A-2,  Class B, Class C,
Class D, Class E and Class F Certificates  (collectively,  the "Publicly Offered
Certificates")  to Deutsche  Morgan  Grenfell  Inc. and Lehman  Brothers Inc. as
representatives   (the   "Representatives")   for   themselves   and  the  other
underwriters (the "Underwriters") named in the Underwriting Agreement,  dated as
of April 28, 1998 (the "Underwriting Agreement"), among the Company, the Seller,
and the Representatives,  and sold the Class G, Class H, Class J, Class K, Class
L,  Class M,  Class N,  Class  R-I,  Class  R-II and  Class  R-III  Certificates
(collectively, the "Privately Offered Certificates") to Deutsche Morgan Grenfell
Inc. and Lehman Brothers Inc. as initial  purchasers (the "Initial  Purchasers")
pursuant to the Certificate Purchase Agreement,  dated as of April 28, 1998 (the
"Certificate Purchase Agreement"), among the Company, the Seller and the Initial
Purchasers.

                                     D-3A-1

<PAGE>


     In connection with rendering this opinion  letter,  I have examined or have
caused  persons under my  supervision  to examine the  Agreements and such other
records and other documents as I have deemed  necessary.  I have further assumed
that  there  is not  and  will  not  be  any  other  agreement  that  materially
supplements or otherwise modifies the agreements expressed in the Agreements. As
to matters of fact, I have examined and relied upon  representations  of parties
contained   in  the   Agreements   and,   where  I  have   deemed   appropriate,
representations  and certifications of officers of 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.   The Seller 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, and to enter into
     and perform its obligations under the Agreements.

2.   Each of the Agreements has been duly and validly  authorized,  executed and
     delivered by the Seller and, upon due authorization, execution and delivery
     by the other parties thereto,  will constitute the valid, legal and binding
     agreements of the Seller, enforceable against the Seller in accordance with
     their terms,  except as  enforceability  may be limited by (i)  bankruptcy,
     insolvency, liquidation,  receivership, moratorium, reorganization or other
     similar laws affecting the rights of creditors,  (ii) general principles of
     equity,  whether enforcement is sought in a proceeding in equity or at law,
     and (iii) public policy  considerations  underlying the securities laws, to
     the extent that such public policy  considerations limit the enforceability
     of  the   provisions   of  the   Agreements   which   purport   to  provide
     indemnification with respect to securities law violations.

                                     D-3A-2

<PAGE>


3.   No  consent,  approval,  authorization  or  order  of the  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.

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 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.

                   FORM OF OPINION II OF COUNSEL TO THE SELLER



                                                                    EXHIBIT 99.2
                                                                  EXECUTION COPY


                        MORTGAGE LOAN PURCHASE AGREEMENT


     This Mortgage  Loan Purchase  Agreement  (this  "Agreement"),  is dated and
effective as of April 28, 1998,  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 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 May 1, 1998 (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 National Bank 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.

     The  Purchaser  intends to sell  certain of the  Certificates  to  Deutsche
Morgan Grenfell Inc.,  Lehman Brothers Inc. and Residential  Funding  Securities
Corp. (together, the "Underwriters") pursuant to an underwriting agreement dated
the date hereof (the  "Underwriting  Agreement").  The Purchaser intends to sell
the  remaining  Certificates  (the  "Non-Registered  Certificates")  to Deutsche
Morgan  Grenfell  Inc.  and Lehman  Brothers  Inc.  (the  "Initial  Purchasers),
pursuant  to a  certificate  purchase  agreement  dated  the  date  hereof  (the
"Certificate Purchase Agreement").

     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 18, 1998 or such
other date as shall be mutually  acceptable to the parties  hereto (the "Closing
Date").  As of the close of business on May 1, 1998 (the  "Cut-off  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  $239,717,501,  subject to a
variance of plus or minus 5%. The purchase price for the Mortgage Loans shall be
determined and paid to the Seller in accordance  with the terms of an allocation
agreement  dated the date  hereof  (the  "Allocation  Agreement"),  to which the
Seller and Purchaser, among others, are parties.

     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 in accordance with the Allocation
Agreement),  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, 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,  and all other  recoveries  of
principal and interest  collected  thereon after the Cut-off Date. All scheduled
payments of principal and interest due thereon on or before the Cut-off Date and
collected after the 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
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


                                       2
<PAGE>

office where such document or instrument has been  delivered for  recordation or
filing,  or because such  original  recorded  document has been lost or returned
from the recording or filing office and  subsequently  lost, as the case may be,
the  delivery  requirements  of this  Section  2(b) shall be deemed to have been
satisfied as to such missing item, and such missing item shall be deemed to have
been  included  in the  related  Mortgage  File,  provided  that a copy  of such
document or instrument  (without  evidence of recording or filing  thereon,  but
certified   (which   certificate  may  relate  to  multiple   documents   and/or
instruments)  by the  Seller  to be a true  and  complete  copy of the  original
thereof  submitted  for  recording  or  filing,  as the  case  may be) has  been
delivered  to the Trustee,  and either the original of such missing  document or
instrument, or a copy thereof, with evidence of recording or filing, as the case
may be,  thereon,  is delivered to or at the  direction of the Purchaser (or any
subsequent owner of the affected Mortgage Loan, including without limitation the
Trustee) within 180 days of the Closing Date (or within such longer period after
the Closing Date as the  Purchaser  (or such  subsequent  owner) may consent to,
which  consent  shall not be  unreasonably  withheld  so long as the  Seller has
provided  the  Purchaser  (or  such  subsequent  owner)  with  evidence  of such
recording or filing,  as the case may be, or has  certified to the Purchaser (or
such subsequent  owner) as to the occurrence of such recording or filing, as the
case may be, and is, as certified to the Purchaser (or such subsequent owner) no
less  often  than  quarterly,  in good  faith  attempting  to  obtain  from  the
appropriate  county  recorder's or filing office such original or copy).  If the
Seller cannot  deliver,  or cause to be delivered,  as to any Mortgage Loan, the
original or a copy of the related lender's title insurance policy referred to in
clause (ix) of Exhibit B solely because such policy has not yet been issued, the
delivery requirements of this Section 2(b) shall be deemed to be satisfied as to
such missing  item,  and such missing item shall be deemed to have been included
in the related  Mortgage  File,  provided  that the Seller has  delivered to the
Trustee a  commitment  for title  insurance  "marked-up"  at the closing of such
Mortgage  Loan,  and the  Seller  shall  deliver to or at the  direction  of the
Purchaser (or any  subsequent  owner of the affected  Mortgage  Loan,  including
without  limitation the Trustee),  promptly  following the receipt thereof,  the
original  related  lender's  title  insurance  policy  (or a copy  thereof).  In
addition,  notwithstanding  anything to the contrary  contained herein, if there
exists with respect to any group of related cross-collateralized  Mortgage Loans
only one  original of any  document  referred  to in Exhibit B covering  all the
Mortgage  Loans  in such  group,  then the  inclusion  of the  original  of such
document in the Mortgage File for any of the Mortgage  Loans in such group shall
be deemed an  inclusion  of such  original  in the  Mortgage  File for each such
Mortgage Loan. On the Closing Date, upon  notification  from the Seller that the
purchase price  referred to in Section 1 (exclusive of any  applicable  holdback
for transaction  expenses in accordance with the Allocation  Agreement) 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 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; 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


                                      3
<PAGE>

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  Maryland,  and is in
     compliance  with the laws of each State in which any Mortgaged  Property is
     located  to the  extent  necessary  to ensure 


                                       4
<PAGE>

          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  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

                                       5
<PAGE>

          with the sale of the Mortgage Loans or the  consummation of any of the
          other transactions contemplated hereby.

               (viii) Neither the Seller nor anyone acting on its behalf has (A)
          offered,  pledged,  sold,  disposed of or  otherwise  transferred  any
          Certificate,  any  interest in any  Certificate  or any other  similar
          security to any person in any manner,  (B)  solicited any offer to buy
          or  to  accept  a  pledge,   disposition  or  other  transfer  of  any
          Certificate,  any  interest in any  Certificate  or any other  similar
          security from any person in any manner,  (C)  otherwise  approached or
          negotiated  with  respect  to any  Certificate,  any  interest  in any
          Certificate  or any  other  similar  security  with any  person in any
          manner,  (D)  made  any  general  solicitation  by  means  of  general
          advertising  or in any other manner with  respect to any  Certificate,
          any interest in any Certificate or any similar security,  or (E) taken
          any other  action,  that (in the case of any of the acts  described in
          clauses  (A)  through  (E)  above)  would  constitute  or  result in a
          violation of the Securities  Act or any state  securities law relating
          to or in connection  with the issuance of the  Certificates or require
          registration  or  qualification  pursuant to the Securities Act or any
          state securities law of any Certificate not otherwise intended to be a
          Registered Certificate.  In addition, the Seller will not act, nor has
          it  authorized  or will it authorize  any person to act, in any manner
          set  forth  in  the  foregoing  sentence  with  respect  to any of the
          Certificates  or interests  therein.  For  purposes of this  paragraph
          4(b)(viii),  the term "similar  security"  shall be deemed to include,
          without limitation,  any security  evidencing or, upon issuance,  that
          would  have  evidenced  an  interest  in  the  Mortgage  Loans  or any
          substantial number thereof.

               (ix) Insofar as it relates to the Mortgage Loans, the information
          set  forth on pages A-9  through  A-13,  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/or
          the Seller and does not represent a restatement  or aggregation 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 of the Prospectus Supplement--The Mortgage
          Asset Pool",  "Risk  Factors--The  Mortgage Loans" and "Description of
          the  Mortgage  Asset  Pool",  set  forth on Annex A to the  Prospectus
          Supplement and (to the extent it contains information  consistent with
          that on such Annex A) set forth on the Diskette,  does not contain any
          untrue statement of a material fact or (in the case of the Memorandum,
          when read together  with the other  information  specified  therein as
          being  available for review by  investors)  omit to state any material
          fact  necessary  to make  the  statements  therein,  in  light  of the
          circumstances under which they were made, not misleading.

               (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

                                       6
<PAGE>

          the Seller of any transaction  contemplated hereby, other than (1) the
          filing or recording of financing statements, instruments of assignment
          and other similar documents necessary in connection with Seller's sale
          of the Mortgage Loans to the Purchaser, (2) such consents,  approvals,
          authorizations,  qualifications,  registrations, filings or notices as
          have been  obtained  or made and (3)  where the lack of such  consent,
          approval, authorization, qualification, registration, filing or notice
          would not have a material  adverse  effect on the  performance  by the
          Seller under this Agreement.

     (c) Upon  discovery by any of the parties  hereto of a breach of any of the
representations  and warranties made pursuant to and set forth in subsection (b)
above which materially and adversely affects the interests of the Purchaser or a
breach of any of the  representations and warranties made pursuant to subsection
(a) above and set forth in Exhibit C which materially and adversely  affects the
value of any  Mortgage  Loan or the  interests  therein of the  Purchaser or its
successors  and  assigns  (including,  without  limitation  the  Trustee and the
holders of the  Certificates),  the party  discovering  such  breach  shall give
prompt written notice to the other party hereto.

     SECTION 5. Representations, Warranties and Covenants of the Purchaser.

     (a) The Purchaser,  as of the date hereof,  hereby  represents and warrants
to, and covenants with, the Seller that:

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

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

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

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

                                       7
<PAGE>

          (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.

     (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)  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, 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 


                                       8
<PAGE>

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) 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.

     For purposes of the foregoing,  and subject to the following paragraph, the
"Permitted  Cure Period"  applicable to any Defect or Material Breach in respect
of any  Mortgage  Loan  shall be the 90-day  period  immediately  following  the
earlier  of the  discovery  by the  Seller or receipt by the Seller of notice of
such Defect or Material Breach, as the case may be; provided that if such Defect
or Material  Breach,  as the case may be,  cannot be  corrected  or cured in all
material respects within such 90-day period,  but is reasonably likely that such
Defect or  Material  Breach,  as the case may be,  could be  corrected  or cured
within 180 days of the  earlier of  discovery  by the Seller and  receipt by the
Seller of notice of such Material  Documents Defect or Material  Breach,  as the
case may be, and the Seller is diligently  attempting to effect such  correction
or cure,  then the applicable  Permitted Cure Period shall,  with the consent of
the  Purchaser  or  its  assignee  (which  consent  shall  not  be  unreasonably
withheld), be extended for an additional 90 days.

     If the Seller is notified of a defect in any Mortgage File that corresponds
to  information  set forth in the  Mortgage  Loan  Schedule,  the  Seller  shall
promptly correct such defect and provide a new, corrected Mortgage Loan Schedule
to the  Purchaser,  which  corrected  Mortgage Loan Schedule  shall be deemed to
amend and replace the existing Mortgage Loan Schedule for all purposes.

     (b)  Notwithstanding  Section  6(a),  within  60  days  of the  earlier  of
discovery or receipt of notice by the Seller,  from either the  Purchaser or any
successor  or assign  thereof,  that any  Mortgage  Loan does not  constitute  a
"qualified  mortgage" within the meaning of Section  860G(a)(3) of the Code, the
Seller shall repurchase such Mortgage Loan from the then owner(s) thereof at the
applicable  Purchase Price by payment of such Purchase Price by wire transfer of
immediately available funds to the account designated by such owner(s).

     (c) In connection  with any  repurchase of or  substitution  for a Mortgage
Loan  contemplated by this Section 6, the then owner(s)  thereof shall tender or
cause to be tendered promptly to the Seller, upon delivery of a receipt executed
by the Seller,  the related  Mortgage File and Servicing File, and each document
that  constitutes  a part of the Mortgage  File that was endorsed or assigned to
the Purchaser or the Trustee shall be endorsed or assigned,  as the case may be,
to the  Seller  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 


                                       9
<PAGE>

of any representation or warranty made pursuant to Section 4(a) and set forth in
Exhibit C, or in connection with the circumstances described in Section 6(b). If
the Seller  defaults on its  obligations  to  repurchase  any  Mortgage  Loan in
accordance  with Section 6(a) or 6(b) or disputes its  obligation  to repurchase
any Mortgage Loan in accordance  with either such  subsection,  the Purchaser or
its  successors  and assigns may take such action as is  appropriate  to enforce
such payment or performance,  including, without limitation, the institution and
prosecution of appropriate proceedings. The Seller shall reimburse the Purchaser
for all necessary and reasonable costs and expenses  incurred in connection with
such enforcement.

     SECTION 7. Closing.

     The closing of the sale of the Mortgage Loans (the "Closing") shall be held
at the offices of Orrick,  Herrington  & Sutcliffe  LLP, 666 Fifth  Avenue,  New

     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  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.

                                       10
<PAGE>

     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:

     SECTION 9. Indemnification.

     (a) The Seller  agrees to indemnify and hold  harmless the  Purchaser,  its

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

<PAGE>

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 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

under the headings "Summary of Prospectus Supplement - The Mortgage Asset Pool",
"Risk Factors - The Mortgage  Loans" and/or  "Description  of the Mortgage Asset
Pool" or contained on Annex A to the  Prospectus  Supplement  (exclusive  of the
Loan  Detail),  and  such  information  does  not  represent  a  restatement  or
aggregation  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.  333-37717  filed  by the  Purchaser  on Form  S-3,
including  without  limitation  exhibits  thereto and  information  incorporated

"Prospectus Supplement"), relating to the Registered Certificates;  "Memorandum"
shall mean the private  placement  memorandum dated April 28, 1998,  relating to
the  Non-Registered  Certificates;  "Computational  Materials"  shall  have  the
meaning  assigned  thereto in the no-action  letter dated May 20, 1994 issued by
the Division of Corporation  Finance of the  Securities and Exchange  Commission
(the "Commission") to Kidder,  Peabody Acceptance Corporation I, Kidder, Peabody
& Co.  Incorporated,  and Kidder  Structured Asset Corporation and the no-action
letter dated May 27, 1994 issued by the Division of  Corporation  Finance of the
Commission  to  the  Public  Securities  Association   (together,   the  "Kidder
Letters");  and "ABS Term Sheets" shall have the meaning assigned thereto in the
no-action  letter dated  February 17, 1995 issued by the Division of Corporation
Finance of the Commission to the Public Securities Association (the "PSA Letter"
and, together with the Kidder Letters, the "No-Action Letters").

     (b) Promptly after receipt by any person entitled to indemnification  under
this Section 9 (each, an "indemnified  party") of notice of the  commencement of
any action,  such indemnified party will, if a claim in respect thereof is to be
made against the Seller (the "indemnifying  party")


                                       12
<PAGE>

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  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 


                                       13
<PAGE>

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 in accordance with the Allocation Agreement.

     SECTION 11. Notices.

     All demands,  notices and communications  hereunder shall be in writing and

Purchaser, addressed to GMAC Commercial Mortgage Securities, Inc. at 650 Dresher

number as the Seller may designate in writing to the Purchaser.

     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


                                       14
<PAGE>

enforced by or on behalf of any such person or entity  against the Seller to the
same extent as if it was a party hereto.

     SECTION 13. Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,
incorporated herein by reference or contained in the certificates of officers of
the Seller submitted  pursuant hereto,  shall remain operative and in full force
and effect and shall survive delivery of the Mortgage Loans by the Seller to the
Purchaser or its designee.

     SECTION 14. Severability of Provisions.

     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 15. 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 16. 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 17. 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 18. Successors and Assigns.

any  corporation  or other  entity  resulting  from any  merger,  conversion  or
consolidation to which the Seller is a party, or any person succeeding to all or
substantially  all of the business of the Seller,  shall be the successor to the
Seller hereunder.  The Purchaser has the right to assign its interest under this
Agreement, in whole or in part, as may be required to effect the purposes of the
Pooling and Servicing  Agreement,  and the assignee shall, to the extent of such
assignment,  succeed to the rights and  obligations  hereunder of the Purchaser.

                assignment  from the originator of the Mortgage Loan to the most

                thereon) and which were in the  possession of the Seller (or its

                                    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,
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 related  Mortgage  constitutes a valid
first lien upon the related Mortgaged Property,  including all buildings located
thereon and all fixtures attached  thereto,  such lien being subject only to (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,  and (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 (the
exceptions  set forth in the  foregoing  clauses (A), (B) and (C)  collectively,
"Permitted   Encumbrances").   The  Permitted  Encumbrances  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  


                                      C-1
<PAGE>

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, to the extent such security interest can
be perfected by the  recordation  of a Mortgage or the filing of a UCC financing
statement,  in all personal property owned by the Mortgagor that is used in, and
is reasonably necessary to, the operation of the related Mortgaged Property.

        (vi) Title Insurance.  The lien of the related Mortgage is insured by an
ALTA lender's  title  insurance  policy ("Title  Policy"),  or its equivalent as
adopted in the applicable jurisdiction,  issued by a nationally recognized title
insurance company, insuring the originator of such Mortgage Loan, its successors
and  assigns,  as to the first  priority  lien of the  Mortgage in the  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.  To the  Seller's
actual  knowledge,  the insurer that issued such Title Policy is qualified to do
business in the state in which the related Mortgaged Property is located,

        (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

                                      C-2
<PAGE>

Mortgage Loan have been fully  disbursed and there is no requirement  for future
advances thereunder.

        (xii)  Enforceability.  The related  Mortgage  Note and Mortgage and all
other documents and instruments evidencing,  guaranteeing, insuring or otherwise
securing such Mortgage Loan have been duly and properly  executed by the parties
thereto,  and each is the  legal,  valid  and  binding  obligation  of the maker
thereof  (subject  to  any  non-recourse  provisions  contained  in  any  of the
foregoing  agreements and any  applicable  state  anti-deficiency  legislation),
enforceable  in accordance  with its terms,  except as such  enforcement  may be
limited by bankruptcy, insolvency,  reorganization,  receivership, moratorium or
other laws  relating to or affecting  the rights of creditors  generally  and by
general  principles  of  equity  (regardless  of  whether  such  enforcement  is
considered in a proceeding in equity or at law).

        (xiii) Insurance.  All improvements upon the related Mortgaged  Property
are insured  against loss by hazards of extended  coverage in an amount (subject
to a  customary  deductible)  at least  equal to the  lesser of the  outstanding
principal balance of such Mortgage Loan and 100% of the full replacement cost of
the  improvements  located on such  Mortgaged  Property  and the related  hazard
insurance policy contains  appropriate  endorsements to avoid the application of
co-insurance   and  does  not  permit   reduction  in  insurance   proceeds  for
depreciation.  If any portion of the related Mortgaged Property was, at the time
of the  origination of such Mortgage Loan, in an area  identified in the Federal
Register by the Federal  Emergency  Management  Agency as having  special  flood
hazards, and flood insurance was available, a flood insurance policy meeting any
requirements   of  the  then  current   guidelines  of  the  Federal   Insurance
Administration is in effect with a generally acceptable insurance carrier, in an
amount  representing  coverage  not less than the  least of (1) the  outstanding
principal  balance of such Mortgage Loan,  (2) the full insurable  value of such
Mortgaged  Property,  (3) the maximum  amount of insurance  available  under the
National  Flood  Insurance  Act  of  1968,  as  amended,  and  (4)  100%  of the
replacement  cost of the  improvements  located on such Mortgaged  Property.  In
addition,  the  Mortgage  requires  the  Mortgagor to maintain in respect of the
Mortgaged  Property   comprehensive   general  liability  insurance  in  amounts
generally  required  by the Seller,  and at least six months  rental or business
interruption  insurance,  and all such insurance  required by the Mortgage to be
maintained  is in full force and effect.  Each such  insurance  policy  requires
prior notice to the holder of the Mortgage of termination or  cancellation,  and
no such  notice  has been  received,  including  any  notice  of  nonpayment  of
premiums, that has not been cured.

        (xiv)  Environmental  Condition.  The  related  Mortgaged  Property  was
subject  to one or  more  environmental  site  assessments  (or an  update  of a
previously  conducted  assessment),  which was (were) performed on behalf of the
Seller,  or as to which  the  related  report  was  delivered  to the  Seller in
connection  with its  origination  or acquisition of such Mortgage Loan; and the
Seller,  having made no  independent  inquiry other than reviewing the resulting
report(s)  and/or   employing  an   environmental   consultant  to  perform  the
assessment(s)  referenced  herein,  has no knowledge of any material and adverse
environmental  conditions or circumstance affecting such Mortgaged Property that
was not disclosed in the related report(s).  The Seller has not taken 


                                      C-3
<PAGE>

any action with respect to such Mortgage Loan or the related Mortgaged  Property
that could subject the  Purchaser,  or its  successors and assigns in respect of
the  Mortgage  Loan,  to any  liability  under the  Comprehensive  Environmental
Response,  Compensation and Liability Act of 1980, as amended  ("CERCLA") or any
other applicable  federal,  state or local environmental law, and the Seller has
not  received  any  actual  notice  of a  material  violation  of  CERCLA or any
applicable federal, state or local environmental law with respect to the related
Mortgaged  Property  that was not disclosed in the related  report.  The related
Mortgage or loan  documents in the related  Mortgage File requires the Mortgagor
to comply with all applicable  federal,  state and local  environmental laws and
regulations.

        (xv) No Cross-Collateralization with Other Mortgage Loans. Such Mortgage
Loan is not  cross-collateralized  with  any  mortgage  loan  that  will  not be
included in the Trust Fund.

        (xvi) Waivers and  Modifications.  The terms of the related Mortgage and
the Mortgage  Note have not been  impaired,  waived,  altered or modified in any
material respect, except as specifically set forth in the related Mortgage File.

        (xvii) Taxes and  Assessments.  There are no  delinquent  taxes,  ground
rents,  assessments  for  improvements  or  other  similar  outstanding  charges
affecting  the  related  Mortgaged  Property  which are or may  become a lien of
priority equal to or higher than the lien of the related Mortgage.  For purposes
of this  representation and warranty,  real property taxes and assessments 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 one Mortgage  Loan 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 


                                      C-4
<PAGE>

is in recordable  form and  constitutes a legal,  valid and binding  assignment,
sufficient to convey to the assignee named therein all of the assignor's  right,
title and interest in, to and under such Assignment of Leases.

        (xxi) Escrows.  All escrow deposits  relating to such Mortgage Loan that
are, as of the Closing Date,  required to be deposited with the mortgagee or its
agent have been so deposited.

        (xxii)  No  Mechanics'  or  Materialmen's  Liens.  As  of  the  date  of
origination of such Mortgage Loan and, to the actual knowledge of the Seller, as
of the Closing Date, the related Mortgaged Property was and is free and clear of
any  mechanics'  and  materialmen's  liens or liens in the nature  thereof which
create a lien prior to that created by the related Mortgage,  except those which
are insured against by the Title Policy referred to in (vi) above.

        (xxiii) No Material  Encroachments.  To the Seller's knowledge (based on
surveys and/or title  insurance  obtained in connection  with the origination of
such Mortgage Loan), as of the date of such origination, no improvement that was
included  for the  purpose of  determining  the  appraised  value of the related
Mortgaged  Property at the time of origination of such Mortgage Loan lay outside
the boundaries and building  restriction  lines of such property to any material
extent  (unless  affirmatively  covered by the title  insurance  referred  to in
paragraph (vi) above),  and no improvements on adjoining  properties  encroached
upon such Mortgaged Property to any material extent. To the Seller's  knowledge,
based upon opinions of counsel and/or other due diligence  customarily performed
by the Seller,  the  improvements  located on or forming part of such  Mortgaged
Property  comply  in all  material  respects  with  applicable  zoning  laws and
ordinances  (except to the extent that they may constitute legal  non-conforming
uses).

        (xxiv)  Originator  Authorized.  To the extent required under applicable
law as of the Closing Date,  the originator of such Mortgage Loan was authorized
to do business in the  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.

                                      C-5
<PAGE>

        (xxvii) No Equity  Participation  or Contingent  Interest.  The Mortgage
Loan contains no equity  participation  by the lender,  and does not provide for
any contingent or additional  interest in the form of  participation in the cash
flow of the related Mortgaged Property, or for negative amortization.

        (xxviii) No Advances of Funds.  No holder of the  Mortgage  Loan has, to
the  Seller's  knowledge,  advanced  funds or induced,  solicited  or  knowingly
received  any  advance of funds from a party other than the owner of the related
Mortgaged  Property,  directly  or  indirectly,  for the  payment  of any amount
required by the Mortgage Loan.

        (xxix) Licenses,  Permits, Etc. To the Seller's knowledge,  based on due
diligence  customarily performed in the origination of comparable mortgage loans
by the Seller,  as of the date of  origination of the Mortgage Loan, the related
Mortgagor or operator of the related Mortgaged Property was in possession of all
material licenses,  permits and  authorizations  required by applicable laws for
the  ownership and  operation of the related  Mortgaged  Property as it was then
operated and if a related  Mortgaged  Property is improved by a skilled nursing,
congregate  care or assisted  living  facility,  the most recent  inspection  or
survey by governmental  authorities having  jurisdiction in connection with such
licenses,  permits and  authorizations  did not cite such Mortgaged Property for
material  violations  (which  shall  include  only  "Level  A"  (or  equivalent)
violations in the case of skilled nursing facilities) that had not been cured or
as to which a plan of correction  had not been submitted to and accepted by such
governmental  authorities.  To the extent such facility participates in Medicaid
or Medicare,  such facility is in  compliance in all material  respects with the
requirements of such program.

        (xxx)  Servicing.  The  servicing  and  collection  practices  used with
respect to the Mortgage Loan have complied with  applicable  law in all material
respects and are  consistent  with the  servicing  standard set forth in Section
3.01(a) of the Pooling and Servicing Agreement.

        (xxxi)  Customary  Remedies.  The related  Mortgage  or  Mortgage  Note,
together  with  applicable  state  law,   contains   customary  and  enforceable
provisions  (subject to the exceptions set forth in paragraph  (xii)) such as to
render the rights and remedies of the holders thereof adequate 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
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 each  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

                                      C-6
<PAGE>

principal balance of the Mortgage Loan on such date;  provided that for purposes
hereof,  the fair  market  value of the real  property  interest  must  first be
reduced  by (X) the  amount of any lien on the real  property  interest  that is
senior to the Mortgage Loan and (Y) a  proportionate  amount of any lien that is
in parity with the Mortgage Loan (unless such other lien secures a Mortgage Loan
that is  cross-collateralized  with  such  Mortgage  Loan,  in which  event  the
computation described in clauses (1) and (2) of this paragraph (xxxiii) shall be
made on a pro rata  basis in  accordance  with the  fair  market  values  of the
Mortgaged Properties securing such  cross-collateralized  Mortgage Loans; or (B)
substantially  all the  proceeds  of such  Mortgage  Loan were used to  acquire,
improve or protect the real property  which served as the only security for such
Mortgage  Loan  (other  than a recourse  feature  or other  third  party  credit
enhancement    within   the    meaning   of   Treasury    Regulations    Section
1.860G-2(a)(1)(ii)).

        (xxxiv) LTV and  Significant  Modifications.  If the  Mortgage  Loan was
"significantly  modified" prior to the Closing Date so as to result in a taxable
exchange  under Section 1001 of the Code, it either (A) was modified as a result
of the default or  reasonably  foreseeable  default of such Mortgage Loan or (B)
satisfies  the  provisions  of  either  clause  (A)(1)  of  paragraph   (xxxiii)
(substituting  the date of the last such  modification for the date the Mortgage
Loan was  originated)  or clause  (A)(2) of paragraph  (xxxiii),  including  the
proviso thereto.

        (xxxv) [Reserved.]

        (xxxvi)  Litigation.  To the  Seller's  actual  knowledge,  there are no
pending  actions,  suits or proceedings  by or before any court or  governmental
authority  against or affecting the related  Mortgagor or the related  Mortgaged
Property that, if determined  adversely to such Mortgagor or Mortgaged Property,
would materially and adversely affect the value of the Mortgaged Property or the
ability of the  Mortgagor to pay  principal,  interest or any other  amounts due
under such Mortgage Loan.

        (xxxvii)  Leasehold  Estate.  Each  Mortgaged  Property  consists of the
related Mortgagor's fee simple estate in real estate or, if the related Mortgage
Loan is secured in whole or in part by the  interest of a Mortgagor  as a lessee
under a ground lease of a Mortgaged Property (a "Ground Lease"),  by the related
Mortgagor's  interest in the Ground Lease but not by the related fee interest in
such Mortgaged  Property (the "Fee Interest") or if the Mortgage Loan is secured
in whole or in part by a Ground Lease and a Fee Interest,  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,  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, 


                                      C-7
<PAGE>

                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  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)     A mortgagee is permitted a  reasonable  opportunity  (including,
                where  necessary,  sufficient  time  to gain  possession  of the
                interest  of the  lessee  under such  Ground  Lease) to cure any
                default  under such  Ground  Lease,  which is curable  after the
                receipt  of  notice  of any  such  default,  before  the  lessor
                thereunder may terminate such Ground Lease;

        (g)     Such Ground Lease has an original term  (including any extension
                options set forth therein) which extends not less than ten years
                beyond the Stated Maturity Date of the related Mortgage Loan;

        (h)     Under the terms of such Ground  Lease and the related  Mortgage,
                taken  together,  any related  insurance  proceeds other than in
                respect of a total or substantially  total loss or taking,  will
                be applied either to the repair or restoration of all or part of
                the related Mortgaged Property,  with the mortgagee or a trustee
                appointed  by it  having  the  right to hold and  disburse


                                      C-8
<PAGE>

                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; and

        (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.


        (j)     Such Ground Lease  requires the lessor to enter into a new lease
                in the event of a termination of the Ground Lease by reason of a
                default  by the  Mortgagor  under the Ground  Lease,  including,
                rejection of the ground lease in a bankruptcy proceeding.

        (xxxviii) Deed of Trust.  If the related  Mortgage is a deed of trust, a
trustee,  duly  qualified  under  applicable  law to serve as such,  is properly
designated and serving under such Mortgage.

        (xxxix) Lien  Releases.  Except in cases where either (a) a release of a
portion  of the  Mortgaged  Property  was  contemplated  at  origination  of the
Mortgage  Loan and such  portion was not  considered  material  for  purposes of
underwriting   the  Mortgage  Loan  or  (b)  release  is  conditioned  upon  the
satisfaction of certain underwriting and legal requirements and the payment of a
release price, the related Mortgage Note or Mortgage does not require the holder
thereof to release all or any portion of the Mortgaged Property from the lien of
the related  Mortgage  except upon payment in full of all amounts due under such
Mortgage Loan.

        (xl)  Junior  Liens.  The  Mortgage  Loan does not  permit  the  related
Mortgaged  Property to be encumbered by any lien junior to or of equal  priority
with the lien of the related  Mortgage  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.

                                      C-9
<PAGE>

        (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. Except for those Mortgage Loans identified
on Schedule C-1 hereto which  represent  4.45% of the Mortgage  Loans by Cut-Off
Date Principal  Balance,  the Mortgagor is an entity,  other than an individual,
whose  organizational  documents or the related Mortgage Loan Documents  provide
substantially  to the  effect  that the  Mortgagor:  (a) is formed or  organized
solely  for the  purpose of owning and  operating  one or more of the  Mortgaged
Properties  securing  the  Mortgage  Loans,  (b) may not engage in any  business
unrelated to such Mortgaged Property or Mortgaged Properties,  (c) does not have
any 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.

        (xlvi)  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, 1998),  (ii) only with
substitute collateral constituting "government securities" within the meaning of
Treas. Reg. ss. 1.860G-2(a)(8)(i),  and (iii) only to facilitate the disposition
of mortgage real property and not as a part of an arrangement to collateralize a
REMIC offering with obligations that are not real estate mortgages.

        It is understood and agreed that the  representations and warranties set
forth in this Exhibit 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  without  limitation the
Trustee and the holders of the Certificates), notwithstanding any restrictive or
qualified endorsement or assignment.

                            SCHEDULE C-1 to EXHIBIT C

                    REPRESENTATIONS AND WARRANTIES EXCEPTIONS

1. CCRT Properties, L.P. (Grossmont Trolley) - TA1585

     a)   (ii) and (xx).  In order for  Seller to assign  its  interest  in that
          certain  Assignment  of License  Agreement  for  Parking,  Seller must
          notify the San Diego  Metropolitan  Transit  Development  Board of the
          assignment  and must notify its assignee of the  obligation  to notify
          San  Diego  Metropolitan  Transit  Development  Board  of  any  future
          assignments.  In order for assignees to take over  Seller's  interest,
          they are  subject  to both the rights  and the  obligations  under the
          Assignment.

     b)   (xiii).  Insurance  must be maintained  pursuant to the guidelines set
          forth in provision  (xiii),  however the Deed of Trust sets forth that
          the  insurance  may be  maintained  by either the  Mortgagor  or their
          tenants.

     c)   (xxxvii). Mortgagor ground leases the property to a Ground Lessee. The
          Ground  Lessee in turn ground  leases the  property  back to Mortgagor
          pursuant to three separate Ground  Subleases.  This Loan is secured by
          (i) a fee interest in the property  and (ii)  Mortgagor's  interest in
          the three Ground Subleasehold Estates on the property. The Mortgagor's
          interest  in the Ground  Subleases  is subject to the Ground  Lessee's
          interest in the Ground Lease and the Mortgage/Deed of Trust in the fee
          is subject to the Ground  Lease.  Our  responses  are with  respect to
          Mortgagor's Ground Subleasehold interest.

         i)       Mortgagor is the Ground Lessor and the lien  encumbers its fee
                  interest.

         ii)      Provision  (g) of  Section  (xxxvii)  is not true.  The Ground
                  Lease and the underlying  Ground  Subleases expire in 2016, 12
                  years before the Maturity Date of the Mortgage Loan.  However,
                  the Mortgage Loan will continue to be secured by a lien on the
                  fee  estate,  after the  expiration  of the  Ground  Lease and
                  Ground Subleases.

         iii)     In regards to provision  (i) of section  (xxxvii),  the Ground
                  Subleases  do not  specifically  contain a  covenant  that the
                  Ground Sublessor is not permitted to disturb the possession or
                  interest of any  subtenants  of the Ground  Sublessee,  in any
                  manner,  which would materially  adversely affect the security
                  provided by the Mortgage.

Re:  GMAC Commercial Mortgage Corporation,  Mortgage Pass-Through  Certificates,
     Series 1998-C1

Ladies and Gentlemen:

     I am General Counsel to German American Capital Corporation (the "Seller").
In  that  capacity,  I  am  familiar  with  the  issuance  of  certain  Mortgage
Pass-Through  Certificates,  Series  1998-C1  (the  "Certificates"),  evidencing
undivided  interests in a trust fund (the "Trust Fund") consisting  primarily of
certain  mortgage  loans  (the  "Mortgage  Loans"),  pursuant  to a Pooling  and
Servicing  Agreement,  dated  as of May 1,  1998  (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,  LaSalle National Bank as trustee (the "Trustee") and ABN
AMRO Bank N.V. as fiscal agent.

     Certain of the  Mortgage  Loans were  purchased by the  Depositor  from the
GMACCM,  pursuant to, and for the consideration  described in, the Mortgage Loan
Purchase  Agreement,  dated as of April 28,  1998  (the  "GMACCM  Mortgage  Loan
Purchase Agreement"),  between the Depositor and GMACCM. Certain of the Mortgage
Loans were purchased by the Depositor from German American  Capital  Corporation
("GACC"), pursuant to, and for the consideration described in, the Mortgage Loan
Purchase Agreement, dated as of April 28, 1998 (the "GACC Mortgage Loan Purchase
Agreement"),  between GACC and the  Depositor.  The GACC  Mortgage Loan Purchase
Agreement  is  referred  to herein  as the  "Agreement."  Capitalized  terms not
defined  herein  have the  meanings  set  forth  in the  Pooling  and  Servicing
Agreement and the Agreement.  This opinion is rendered  pursuant to Section 8(e)
of the GACC Mortgage Loan Purchase Agreement.

                                     D-3A-1
<PAGE>

     The Depositor has sold the Class X, Class A-1, Class A-2, Class B, Class C,
Class D, Class E and Class F Certificates  (collectively,  the "Publicly Offered
Certificates") to the underwriters pursuant to the Underwriting Agreement, dated
as of April  28,  1998 (the  "Underwriting  Agreement"),  among  the  Depositor,
GMACCM,  and the underwriters named therein and sold the Class G, Class H, Class
J, Class K, Class L,  Class M,  Class N, Class R-I,  Class R-II and Class  R-III
Certificates  (collectively,  the "Privately Offered  Certificates") to Deutsche
Morgan Grenfell Inc. and Lehman Brothers Inc. as initial purchasers  pursuant to
the Certificate Purchase Agreement, dated as of April 28, 1998 (the "Certificate
Purchase Agreement"), among the Depositor, GMACCM and initial purchasers.

     In connection with rendering this opinion  letter,  I have examined or have
caused  persons  under my  supervision  to examine the  Agreement 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 Agreement.  As
to matters of fact, I have examined and relied upon  representations  of parties
contained in the Agreement and, where I have deemed appropriate, representations
and certifications of officers of 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
Agreement.

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

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

1.   The Seller is duly incorporated and is validly existing as a corporation in
     good standing under the laws of the State of Maryland and has the requisite
     power and authority,  


                                     D-3A-2
<PAGE>

     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 Agreement.

2.   The Agreement has been duly and validly authorized,  executed and delivered
     by the Seller and,  upon due  authorization,  execution and delivery by the
     other  parties  thereto,  will  constitute  the  valid,  legal and  binding
     agreements of the Seller enforceable  against the Seller in accordance with
     their terms,  except as  enforceability  may be limited by (i)  bankruptcy,
     insolvency, liquidation,  receivership, moratorium, reorganization or other
     similar laws affecting the rights of creditors,  (ii) general principles of
     equity,  whether enforcement is sought in a proceeding in equity or at law,
     and (iii) public policy  considerations  underlying the securities laws, to
     the extent that such public policy  considerations limit the enforceability
     of the provisions of the Agreement which purport to provide indemnification
     with respect to securities law violations.

3.   No  consent,   approval,   authorization  or  order  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 Agreement,  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 Agreement,
     will result in a material breach of any term or provision of the charter or
     bylaws of the  Seller or any state or  federal  statute  or  regulation  or
     conflict with, result in a material breach, violation or acceleration of or
     constitute  a material  default  under the terms of any  indenture or other
     material agreement or instrument to which the Seller is a party or by which
     it is bound or any  order or  regulation  of any  state or  federal  court,
     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,

Re:  GMAC Commercial Mortgage Corporation,  Mortgage Pass-Through  Certificates,
     Series 1998-C1

Ladies and Gentlemen:

     This  opinion  is being  provided  to you by the  undersigned,  as  special
counsel to German American  Capital  Corporation  ("GACC"),  pursuant to Section
8(e) of the Mortgage  Loan Purchase  Agreement,  dated April 28, 1998 (the "GACC
Mortgage Loan Purchase Agreement"), between GMAC Commercial Mortgage Securities,
Inc. (the "Purchaser") and GACC as the Seller,  (in such capacity the "Seller"),
relating  to the sale by the Seller of  certain  mortgage  loans (the  "Mortgage
Loans"), and pursuant to Section 6.11 of the Underwriting Agreement, dated as of
April 28, 1998,  between the  Purchaser  and Deutsche  Morgan  Grenfell Inc. and
Lehman Brothers Inc., relating to that certain Pooling and Servicing  Agreement,
dated as of May 1, 1998, among GMAC Commercial Mortgage  Corporation  ("GMACCM")
as special  servicer and master  servicer (in such  respective  capacities,  the
"Special Servicer" and the "Master Servicer"),  the Purchaser,  LaSalle National
Bank,  as  trustee  and ABN AMRO Bank N.V.  as fiscal  agent (the  "Pooling  and
Servicing   Agreement"  and  together  with  the  GACC  Mortgage  Loan  Purchase
Agreement,  the  "Agreements").  Capitalized  terms not otherwise defined herein
have the meanings assigned to them in the Agreements.

     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,  and (c) an  executed  copy of the  Pooling  and  Servicing
Agreement.


                                     D-3B-1
<PAGE>

     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.

     We have not ourselves checked the accuracy or completeness of, or otherwise
independently verified, the information furnished with respect to the Prospectus
or the Memorandum.  In addition,  as you are aware, we did not examine or review
the Mortgage Files.  However,  in the course of the preparation by the Purchaser
of the Prospectus and the Memorandum,  we have  participated in conferences with
certain officers of the Seller, the Purchaser, counsel to the Purchaser and your
representatives,  during which the contents of the Prospectus and the Memorandum
and related matters were discussed.  On the basis of the discussions 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 and the  Memorandum,  and without  independent  check or verification
except as stated,  no facts have come to our  attention  that have  caused us to
believe that either the Prospectus 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  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 [Insert Name of Counsel to Seller]  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,
