on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-6 Certificates on such Distribution  Date. The
Notional Amount of the Class A-6 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-6  Certificates  have no
Certificate Principal Balance.

Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the account of the Person entitled

thereto if such Person shall have so notified the Master Servicer or such Paying
Agent, or by check mailed to the address of the Person entitled thereto, as such
name and address shall appear on the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the

in  certain  circumstances  without  the  consent  of the  Holders of any of the
Certificates and, in certain  additional  circumstances,  without the consent of
the Holders of certain Classes of Certificates.

                  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

below or other  written  instrument  of  transfer  in form  satisfactory  to the

Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

Certificate is registered as the owner hereof for all purposes,  and neither the
Company,  the Master Servicer,  the Trustee nor any such agent shall be affected
by notice to the contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in

not  require,  the Master  Servicer  or the  Company to (i)  purchase at a price
determined as provided in the Agreement  all  remaining  Mortgage  Loans and all
property acquired in respect of any Mortgage Loan or (ii) purchase in whole, but
not in part, all of the Certificates  from the Holders thereof;  provided,  that
any such option may only be  exercised if the Pool Stated  Principal  Balance of
the Mortgage  Loans as of the  Distribution  Date upon which the proceeds of any
such  purchase  are  distributed  is less than ten percent of the  Cut-off  Date
Principal Balance of the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

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.

         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential

certificate or other obligation secured by or payable from payments
on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-13 Certificates on such Distribution Date. The
Notional Amount of the Class A-13  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-13 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified the Master Servicer

or such Paying Agent,  or by check mailed to the address of the Person  entitled
thereto, as such name and address shall appear on the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing  in the aggregate  not less than 66% of the  Percentage  Interests of
each Class of Certificates  affected thereby.  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 the Certificate. The Agreement also permits the


NY1-192849.1

amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain  additional  circumstances,  without the
consent of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company,  the Master Servicer,  the Trustee nor any such agent shall be affected
by notice to the contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by or on

behalf of the Trustee and required to be paid to them  pursuant to the Agreement
following  the  earlier of (i) the  maturity  or other  liquidation  of the last
Mortgage Loan subject thereto or the  disposition of all property  acquired upon
foreclosure  or deed in lieu of  foreclosure  of any Mortgage  Loan and (ii) the
purchase  by the  Master  Servicer  or the  Company  from the Trust  Fund of all
remaining  Mortgage Loans and all property  acquired in respect of such Mortgage
Loans,  thereby  effecting early retirement of the  Certificates.  The Agreement
permits,  but does not  require,  the  Master  Servicer  or the  Company  to (i)
purchase  at a price  determined  as  provided in the  Agreement  all  remaining
Mortgage Loans and all property acquired in respect of any Mortgage Loan or (ii)
purchase in whole,  but not in part,  all of the  Certificates  from the Holders
thereof; provided, that any such option may only be exercised if the Pool Stated
Principal  Balance of the Mortgage Loans as of the Distribution  Date upon which
the proceeds of any such  purchase are  distributed  is less than ten percent of
the Cut-off Date Principal Balance of the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-11 Certificates on such Distribution Date. The
Notional Amount of the Class A-11  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-11 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified the Master Servicer

or such Paying Agent,  or by check mailed to the address of the Person  entitled
thereto, as such name and address shall appear on the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing  in the aggregate  not less than 66% of the  Percentage  Interests of
each Class of Certificates  affected thereby.  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 the Certificate. The Agreement also permits the

amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain  additional  circumstances,  without the
consent of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company,  the Master Servicer,  the Trustee nor any such agent shall be affected
by notice to the contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by or on

following  the  earlier of (i) the  maturity  or other  liquidation  of the last
Mortgage Loan subject thereto or the  disposition of all property  acquired upon
foreclosure  or deed in lieu of  foreclosure  of any Mortgage  Loan and (ii) the
purchase  by the  Master  Servicer  or the  Company  from the Trust  Fund of all
remaining  Mortgage Loans and all property  acquired in respect of such Mortgage
Loans,  thereby  effecting early retirement of the  Certificates.  The Agreement
permits,  but does not  require,  the  Master  Servicer  or the  Company  to (i)
purchase  at a price  determined  as  provided in the  Agreement  all  remaining
Mortgage Loans and all property acquired in respect of any Mortgage Loan or (ii)
purchase in whole,  but not in part,  all of the  Certificates  from the Holders
thereof; provided, that any such option may only be exercised if the Pool Stated
Principal  Balance of the Mortgage Loans as of the Distribution  Date upon which
the proceeds of any such  purchase are  distributed  is less than ten percent of
the Cut-off Date Principal Balance of the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-8  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest

Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-8 Certificates on such Distribution  Date. The
Notional Amount of the Class A-8 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-8  Certificates  have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-8  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities I, Inc., the Master Servicer, the Trustee or


NY1-191861.2

<PAGE>



GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the
Master Servicer,  GMAC Mortgage Corporation or any of their affiliates will have
any obligation with respect to any certificate or other obligation secured by or
payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-8 Certificates on such Distribution  Date. The
Notional Amount of the Class A-8 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-8  Certificates  have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-191861.2

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-14  Certificates  with  respect  to a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities I, Inc., the Master Servicer, the Trustee or


NY1-192796.2

<PAGE>



GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the
Master Servicer,  GMAC Mortgage Corporation or any of their affiliates will have
any obligation with respect to any certificate or other obligation secured by or
payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,

described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-14 Certificates on such Distribution Date. The
Notional Amount of the Class A-14  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-14 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-5  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities  I,  Inc.,  the  Master  Servicer,   the  Trustee  or  GMAC  Mortgage
Corporation or any of their affiliates. None of the

<PAGE>



Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-5 Certificates on such Distribution  Date. The
Notional Amount of the Class A-5 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-5  Certificates  have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-191683.1

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-10  Certificates  with  respect  to a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest

Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,

registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-10 Certificates on such Distribution Date. The
Notional Amount of the Class A-10  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-10 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-15  Certificates  with  respect  to a  Trust  Fund  consisting

Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred

Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-15 Certificates on such Distribution Date. The
Notional Amount of the Class A-15  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-15 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-5  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities  I,  Inc.,  the  Master  Servicer,   the  Trustee  or  GMAC  Mortgage
Corporation or any of their affiliates. None of the


NY1-191684.1

<PAGE>



Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-5 Certificates on such Distribution  Date. The
Notional Amount of the Class A-5 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-5  Certificates  have no
Certificate Principal Balance.



NY1-191684.1

<PAGE>



                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-191684.1

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the
Master Servicer,  GMAC Mortgage Corporation or any of their affiliates will have
any obligation with respect to any certificate or other obligation secured by or
payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-14 Certificates on such Distribution Date. The
Notional Amount of the Class A-14  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-14 Certificates have no
Certificate Principal Balance.


NY1-192784.2

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-192784.2

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the

Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-14 Certificates on such Distribution Date. The
Notional Amount of the Class A-14  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-14 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the
Master Servicer,  GMAC Mortgage Corporation or any of their affiliates will have
any obligation with respect to any certificate or other obligation secured by or
payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-16 Certificates on such Distribution Date. The
Notional Amount of the Class A-16  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-16 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-9  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any

Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,

month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-9 Certificates on such Distribution  Date. The
Notional Amount of the Class A-9 Certificates as of any date of determination is

Certificate Principal Balance.

Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-3  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities  I,  Inc.,  the  Master  Servicer,   the  Trustee  or  GMAC  Mortgage
Corporation or any of their affiliates. None of the

<PAGE>



Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-3 Certificates on such Distribution  Date. The
Notional Amount of the Class A-3 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-3  Certificates  have no
Certificate Principal Balance.



NY1-192340.1

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-192340.1

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the
         Class  A-7  Certificates  with  respect  to  a  Trust  Fund  consisting
         primarily of a pool of conventional  one- to four-family fixed interest
         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this
Certificate  nor the underlying  Mortgage Loans are guaranteed or insured by any
governmental  agency  or  instrumentality  or by  Residential  Funding  Mortgage
Securities  I,  Inc.,  the  Master  Servicer,   the  Trustee  or  GMAC  Mortgage
Corporation or any of their affiliates. None of the


NY1-191212.2

<PAGE>



Company,  the  Master  Servicer,  GMAC  Mortgage  Corporation  or any  of  their
affiliates  will have any  obligation  with respect to any  certificate or other
obligation secured by or payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified  above (the  "Agreement")  among the Company,  the Master Servicer and
Bankers Trust Company,  as trustee (the "Trustee"),  a summary of certain of the
pertinent provisions of which is set forth hereafter.  To the extent not defined
herein,  the  capitalized  terms used herein have the  meanings  assigned in the
Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-7 Certificates on such Distribution  Date. The
Notional Amount of the Class A-7 Certificates as of any date of determination is
equal to the aggregate  Certificate Principal Balance of the Certificates of all
classes  immediately  prior to such  date.  The Class A-7  Certificates  have no
Certificate Principal Balance.



NY1-191212.2

<PAGE>



                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing


NY1-191212.2

<PAGE>



in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.

         evidencing a percentage interest in the distributions  allocable to the

         rate  first  mortgage  loans  formed  and sold by  RESIDENTIAL  FUNDING
         MORTGAGE SECURITIES I, INC.

                  This  Certificate  is  payable  solely  from the assets of the
Trust Fund,  and does not represent an obligation of or interest in  Residential
Funding Mortgage  Securities I, Inc., the Master Servicer,  the Trustee referred
to below or GMAC Mortgage  Corporation or any of their affiliates.  Neither this

GMAC Mortgage  Corporation or any of their affiliates.  None of the Company, the
Master Servicer,  GMAC Mortgage Corporation or any of their affiliates will have
any obligation with respect to any certificate or other obligation secured by or
payable from payments on the Certificates.

                  This certifies  that  RESIDENTIAL  FUNDING  CORPORATION is the
registered  owner of the Percentage  Interest  evidenced by this  Certificate in
certain  distributions with respect to the Trust Fund consisting primarily of an
interest in a pool of conventional  one-to four-family fixed interest rate first
mortgage loans (the "Mortgage  Loans"),  formed and sold by Residential  Funding
Mortgage  Securities  I, Inc.  (hereinafter  called  the  "Company,"  which term
includes any successor entity under the Agreement  referred to below). The Trust
Fund  was  created  pursuant  to a  Pooling  and  Servicing  Agreement  dated as
specified above (the "Agreement") among the Company, the Master Servicer and The
First National Bank of Chicago, as trustee (the "Trustee"), a summary of certain
of the pertinent  provisions of which is set forth hereafter.  To the extent not
defined herein,  the capitalized terms used herein have the meanings assigned in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, a distribution will be
made on the 25th day of each month or, if such 25th day is not a  Business  Day,
the Business Day immediately following (the "Distribution Date"),  commencing as
described  in the  Agreement,  to the Person in whose name this  Certificate  is
registered  at the close of business on the last day (or if such last day is not
a Business  Day, the Business Day  immediately  preceding  such last day) of the
month immediately  preceding the month of such distribution (the "Record Date"),
from the Available  Distribution Amount in an amount equal to the product of the
Percentage  Interest evidenced by this Certificate and the amount required to be
distributed to Holders of Class A-23 Certificates on such Distribution Date. The
Notional Amount of the Class A-23  Certificates as of any date of  determination
is equal to the aggregate  Certificate  Principal Balance of the Certificates of
all classes  immediately prior to such date. The Class A-23 Certificates have no
Certificate Principal Balance.

                  Distributions  on this  Certificate will be made either by the
Master  Servicer  acting on behalf of the Trustee or by a Paying Agent appointed
by the Trustee in  immediately  available  funds (by wire transfer or otherwise)
for the  account of the Person  entitled  thereto if such  Person  shall have so
notified  the Master  Servicer or such Paying  Agent,  or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

                  Notwithstanding  the  above,  the final  distribution  on this
Certificate  will be made after due notice of the pendency of such  distribution
and only upon  presentation  and surrender of this  Certificate at the office or
agency  appointed  by the Trustee for that  purpose in the City and State of New
York.

                  This  Certificate  is  one  of  a  duly  authorized  issue  of
Certificates  issued in several  Classes  designated  as  Mortgage  Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

                  The  Certificates  are  limited in right of payment to certain
collections  and  recoveries   respecting  the  Mortgage  Loans,   all  as  more
specifically set forth herein and in the Agreement. In the event Master Servicer
funds  are  advanced  with  respect  to  any  Mortgage  Loan,  such  advance  is
reimbursable  to the Master  Servicer,  to the extent provided in the Agreement,
from related recoveries on such Mortgage Loan or from other cash that would have
been distributable to Certificateholders.

                  As provided in the Agreement,  withdrawals  from the Custodial
Account   and/or  the   Certificate   Account   created   for  the   benefit  of
Certificateholders  may be made by the  Master  Servicer  from  time to time for
purposes other than distributions to Certificateholders, such purposes including
without  limitation  reimbursement  to the  Company  and the Master  Servicer of
advances made, or certain expenses incurred, by either of them.

                  The  Agreement   permits,   with  certain  exceptions  therein
provided,  the amendment of the Agreement and the modification of the rights and
obligations of the Company,  the Master  Servicer and the Trustee and the rights
of the  Certificateholders  under the Agreement at any time by the Company,  the
Master  Servicer and the Trustee with the consent of the Holders of Certificates
evidencing

in the aggregate not less than 66% of the Percentage  Interests of each Class of
Certificates   affected  thereby.  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 the  Certificate.  The Agreement also permits the amendment
thereof in certain  circumstances  without  the consent of the Holders of any of
the Certificates and, in certain additional  circumstances,  without the consent
of the Holders of certain Classes of Certificates.

                  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 or agencies  appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other  written  instrument  of  transfer  in form  satisfactory  to the
Trustee and the Certificate Registrar duly executed by the Holder hereof or such
Holder's  attorney  duly  authorized  in writing,  and thereupon one or more new
Certificates of authorized denominations evidencing the same Class and aggregate
Percentage Interest will be issued to the designated transferee or transferees.

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

                  No service  charge will be made for any such  registration  of
transfer or exchange, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the  Master  Servicer,   the  Trustee  and  the
Certificate  Registrar and any agent of the Company,  the Master  Servicer,  the
Trustee  or the  Certificate  Registrar  may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes,  and neither the
Company, the Master

Servicer,  the  Trustee  nor any such agent  shall be  affected by notice to the
contrary.

                  This  Certificate  shall  be  governed  by  and  construed  in
accordance with the laws of the State of New York.

                  The  obligations  created by the  Agreement  in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to  Certificateholders  of all  amounts  held by or on behalf of the Trustee and
required to be paid to them pursuant to the  Agreement  following the earlier of
(i) the maturity or other  liquidation of the last Mortgage Loan subject thereto
or the disposition of all property  acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer or
the Company from the Trust Fund of all remaining Mortgage Loans and all property
acquired in respect of such Mortgage Loans,  thereby  effecting early retirement
of the Certificates.  The Agreement  permits,  but does not require,  the Master
Servicer or the Company to (i) purchase at a price determined as provided in the
Agreement all remaining  Mortgage Loans and all property  acquired in respect of
any  Mortgage  Loan or (ii)  purchase  in  whole,  but not in  part,  all of the
Certificates from the Holders thereof;  provided,  that any such option may only
be exercised if the Pool Stated  Principal  Balance of the Mortgage  Loans as of
the  Distribution  Date  upon  which  the  proceeds  of any  such  purchase  are
distributed  is less than ten percent of the Cut-off Date  Principal  Balance of
the Mortgage Loans.

                  Reference  is hereby  made to the further  provisions  of this
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as if set forth at this place.

                  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.
