The analysis in this report is based on information  provided by Chase Manhattan
Mortgage  Corporation  (the "Seller").  Chase  Securities Inc.  ("CSI") makes no
representations as to the accuracy or completeness of the information  contained
herein.  The  information  contained  herein is qualified in its entirety by the
information in the Prospectus  and Prospectus  Supplement for this  transaction.
The  information  contained  herein  is  preliminary  as  of  the  date  hereof,
supersedes  any  previous  information  delivered  to  you by CSI  and  will  be
superseded by the applicable final Prospectus and Prospectus  Supplement and any
other   information   subsequently   filed  with  the  Securities  and  Exchange
Commission. These materials are subject to change, completion, or amendment from
time to time without notice,  and CSI is under no obligation to keep you advised
of such changes.  These  materials are not intended as an offer or  solicitation
with respect to the purchase or sale of any security.  Any  investment  decision
with respect to the securities  should be made by you based upon the information
contained in the final  Prospectus  Supplement  and  Prospectus  relating to the
securities. You should consult your own counsel,  accountant, and other advisors
as to the legal, tax,  business,  financial and related aspects of a purchase of
these securities.

The attached  information contains certain tables and other statistical analyses
(the "Computational Materials") which have been prepared by CSI in reliance upon
information furnished by the Seller. They may not be provided to any third party
other than the addressee's legal, tax, financial and/or accounting  advisors for
the purposes of evaluating  said  material.  Numerous  assumptions  were used in
preparing the Computational  Materials which may or may not be reflected herein.
As such, no assurance can be given as to the Computational  Materials' accuracy,
appropriateness or completeness in any particular context; nor as to whether the
Computational Materials and/or the assumptions upon which they are based reflect
present  market  conditions or future market  performance.  These  Computational
Materials  should not be construed as either  projections  or  predictions or as
legal, tax, financial or accounting  advice. Any weighted average lives,  yields
and principal payment periods shown in the Computational  Materials are based on
prepayment   assumptions,   and  changes  in  such  prepayment  assumptions  may
dramatically  affect such weighted average lives,  yields and principal  payment
periods.  In addition,  it is possible that prepayments on the underlying assets
will  occur at rates  slower or  faster  than the  rates  shown in the  attached
Computational   Materials.   Furthermore,   unless   otherwise   provided,   the
Computational  Materials  assume  no  losses  on the  underlying  assets  and no
interest shortfalls.  The specific  characteristics of the securities may differ
from those shown in the Computational  Materials due to differences  between the
actual  underlying  assets  and  the  hypothetical  underlying  assets  used  in
preparing the Computational  Materials.  The principal amount and designation of
any security  described  in the  Computational  Materials  are subject to change
prior  to  issuance.   Neither  CSI  nor  any  of  its   affiliates   makes  any
representation or warranty as to the actual rate or timing of payments on any of
the underlying assets or the payments or yield on the securities.

THIS  INFORMATION IS FURNISHED TO YOU SOLELY BY CSI AND NOT BY THE ISSUER OF THE
SECURITIES  OR ANY  OF ITS  AFFILIATES  (OTHER  THAN  CSI).  CSI  IS  ACTING  AS
UNDERWRITER  AND NOT  ACTING AS AGENT  FOR THE  ISSUER  IN  CONNECTION  WITH THE
PROPOSED TRANSACTION.

                                    and the  principal  portion of Advances,  in
                                    each  case   previously   incurred   by  the
                                    Subservicer   in  the   performance  of  its
                                    servicing  obligations  in  connection  with
                                    such mortgage loans.


MORTGAGE LOANS:                     The  mortgage  pool will consist of mortgage
                                    loans   ("Mortgage   Loans")  that  will  be
                                    divided  into  a  fixed  rate  coupon  group
                                    (Group  I)  and  an  adjustable-rate  coupon
                                    group  (Group II).  The  mortgage  loans are
                                    secured by first liens on real properties.


ADMINISTRATIVE FEES:                The Master  Servicer,  Servicer  and Trustee
                                    will be paid fees aggregating  approximately
                                    51 bps per annum  (payable  monthly)  on the
                                    outstanding   principal   balance   of   the

      CHASE FUNDING, MORTGAGE LOAN ASSET-BACKED CERTIFICATES, SERIES 1999-3

                              CERTIFICATE STRUCTURE


CREDIT ENHANCEMENT:                 1) Excess interest
                                    2) Over-Collateralization
                                    3) Cross-Collateralization
                                    4) Subordination


EXCESS INTEREST:                    Excess  interest  cashflows  from each group
                                    will be available as credit  enhancement for
                                    the related group.


OVERCOLLATERALIZATION:              The overcollateralization ("O/C") provisions
                                    are  intended  to  provide  for the  limited
                                    acceleration  of  the  senior   Certificates
                                    relative to the  amortization of the related
                                    mortgage group, generally until the required
                                    O/C   levels   are   reached.    Accelerated
                                    amortization is achieved by applying certain
                                    excess  interest  collected on each mortgage
                                    group to the  payment  of  principal  on the
                                    related  senior  Certificates,  resulting in
                                    the  accumulation of O/C. By paying down the
                                    principal balance of the certificates faster
                                    than  the  principal   amortization  of  the
                                    related       mortgage       group,       an
                                    overcollateralization  amount  equal  to the
                                    excess of the aggregate principal balance of
                                    the   related   mortgage   group   over  the
                                    principal    balance    of    the    related
                                    Certificates  is  created.  Excess  interest
                                    will be directed  to build each  group's O/C
                                    amount until the  respective  mortgage group
                                    reaches its required  O/C target.  Upon this
                                    event, the  acceleration  feature will cease
                                    unless  it  is  once  again   necessary   to
                                    maintain  the   required   O/C  level.   For
                                    purposes  of  applying  excess  interest  to
                                    build  each   group's  O/C  amount,   excess
                                    interest  will  begin to be  applied  to the
                                    Group   I   Certificates   on   the   fourth
                                    Distribution  Date (January 25, 2000) and to
                                    the  Group  II  Certificates  on  the  first
