             STATEMENT   REGARDING   ASSUMPTIONS  AS  TO  SECURITIES,   PRICING
ESTIMATES,  AND OTHER  INFORMATION  The  information  contained  in the attached
materials (the "Information") may include various forms of performance analysis,
security  characteristics  and securities  pricing  estimates for the securities
addressed. Please read and understand this entire statement before utilizing the
Information.  The Information is provided  solely by Bear Stearns,  not as agent
for any  issuer,  and  although  it may be  based on data  supplied  to it by an
issuer,  the  issuer  has not  participated  in its  preparation  and  makes  no
representations  regarding  its  accuracy  or  completeness.  Should you receive
Information  that  refers  to the  "Statement  Regarding  Assumptions  and Other
Information," please refer to this statement instead.

The  Information is  illustrative  and is not intended to predict actual results
which  may  differ  substantially  from  those  reflected  in  the  Information.
Performance analysis is based on certain assumptions with respect to significant
factors  that  may  prove  not  to be as  assumed.  You  should  understand  the
assumptions  and  evaluate  whether  they are  appropriate  for  your  purposes.
Performance  results  are  based  on  mathematical  models  that use  inputs  to
calculate results. As with all models, results may vary significantly  depending
upon the value of the inputs given.  Inputs to these models  include but are not
limited to: prepayment expectations (economic prepayment models, single expected
lifetime  prepayments  or a  vector  of  periodic  prepayments),  interest  rate
assumptions   (parallel  and   nonparallel   changes  for   different   maturity
instruments),  collateral  assumptions (actual pool level data,  aggregated pool
level  data,  reported  factors  or  imputed  factors),  volatility  assumptions
(historically  observed or implied  current) and reported  information  (paydown
factors,  rate resets, and trustee statements).  Models used in any analysis may
be  proprietary  making the results  difficult for any third party to reproduce.
Contact your registered representative for detailed explanations of any modeling
techniques employed in the Information.

The  Information  addresses only certain  aspects of the  applicable  security's
characteristics  and thus does not provide a complete  assessment.  As such, the
Information may not reflect the impact of all structural  characteristics of the
security,  including  call  events and cash flow  priorities  at all  prepayment
speeds and/or interest rates.  You should consider whether the behavior of these
securities should be tested as assumptions  different from those included in the
Information. The assumptions underlying the Information, including structure and
collateral,  may be modified from time to time to reflect changed circumstances.
Any investment  decision  should be based only on the data in the prospectus and
the prospectus  supplement or private placement  memorandum (Offering Documents)
and  the  then  current  version  of the  Information.  Any  information  herein
regarding the  collateral or the  securities  supersedes  any prior  information
regarding the collateral or the securities and will be superseded by information
regarding  the  collateral  and/or  the  securities  contained  in the  Offering
Documents  and  any  subsequent  information  regarding  the  collateral  or the
securities.
Offering  Documents  contain data that is current as of their  publication dates
and after  publication  may no longer be complete or current and any  subsequent
information regarding the collateral or the securities.  Contact your registered
representative  for  Offering  Documents,   current  Information  or  additional
materials,  including other models for performance analysis, which are likely to
produce  different   results,   and  any  further   explanation   regarding  the
Information.

Any pricing  estimates  Bear Stearns has supplied at your request (a)  represent
our view, at the time  determined,  of the  investment  value of the  securities
between the  estimated  bid and offer  levels,  the spread  between which may be
significant due to market volatility or illiquidity, (b) do not constitute a bid
by any  person  for any  security,  (c) may not  constitute  prices at which the
securities  could have been  purchased or sold in any market,  (d) have not been
confirmed by actual  trades,  may vary from the value Bear  Stearns  assigns any
such security while in its inventory,  and may not take into account the size of
a position you have in the  security,  and (e) may have been derived from matrix
pricing  that uses data  relating  to other  securities  whose  prices  are more
readily  ascertainable  to produce a  hypothetical  price based on the estimated
yield spread relationship between the securities.

General Information:  The data underlying the Information has been obtained from
sources that we believe are  reliable,  but we do not  guarantee the accuracy of
the  underlying  data  or  computations  based  thereon.   Bear  Stearns  and/or
individuals  employed  thereby may have positions in these  securities while the
Information is circulating or during such period may engage in transactions with
the issuer or its affiliates.  We act as principal in transactions with you, and
accordingly, you must determine the appropriateness for you of such transactions
and address any legal, tax, or accounting considerations applicable to you. Bear
Stearns shall not be a fiduciary or advisor  unless we have agreed in writing to
receive compensation  specifically to act in such capacities. If you are subject
to ERISA,  the  Information is being furnished on the condition that it will not
form a primary  basis for any  investment  decision.  The  Information  is not a
solicitation  of any  transaction  in  securities  which  may be  made  only  by
prospectus  when required by law, in which event you may obtain such  prospectus
from Bear Stearns.

(a)     100% Prepayment Assumption:

          Home Equity Loans: 5.00% CPR in month 1, and an additional 1.8182% per
          annum in each month thereafter until month 12.

        On and after month 12, 25.00% CPR;
        Fixed Rate Home Loans: 350% PSA;
        Adjustable Rate Home Loans: 40% CPR.
(b)  The Certificates  are priced to a 10% clean-up call. The pass-through  rate
     on the Class A-4,  Class A-5,  Class A-8,  Class M and Class B Certificates
     will  increase  by 0.50%  beginning  on the  date  when  the  current  pool
     principal balance declines to less than 10% of the sum of (i) the principal
     balance of the initial  mortgage  loans as of the cut-off date and (ii) the
     amount on deposit in the pre-funding account on the closing date (the "Pool
     Principal Balance").

(c)  The  lesser of (i)  One-Month  LIBOR  plus the  applicable  margin and (ii)
     [10.00]%.

(d)  If on any  payment  date,  the amount  available  for  distribution  on the
     certificates is less than the amount  necessary in order to pay interest on
     the  certificates  at  the  respective  pass-through  rates  and  principal
     required to be paid to the senior certificates, the Class M and the Class B
     certificates, the amount of interest due on the Class B certificates or, if
     the  Class  B  certificates  are  no  longer  outstanding,  the  Class  M-2
     certificates,  on that  payment  date will be  reduced by the amount of the
     shortfall.

Offering:                           The  Certificates  will be  issued  publicly  from  the  Depositor's  shelf
                                    registration.

Form of Securities:                 Book-entry: Class A, Class M and Class B Certificates.

Prepayment Pricing
Speed Assumption:                   Home  Equity  Loans:  A constant  prepayment  of 5.00% per year of the then
                                    outstanding  principal  balance of the loans in the first month of the life
                                    of the loans and an  additional  1.8182% per year in each month  thereafter
                                    until it  reaches  25.00% on the 12th  month.  Beginning  in the 12th month
                                    and  thereafter  during  the life of such home  equity  loans,  a  constant
                                    prepayment rate of 25.00% per year.
                                    Fixed Rate Home Loans: 350% PSA.
                                    Adjustable Rate Home Loans: 40% CPR.

Payment Date:                       The 25th day of each month  (or,  if that day is not a  business  day,  the
                                    next succeeding business day), commencing November 27, 2000.

          the case of the first  Payment Date) to and including the day prior to
          the then current  Payment  Date at the  applicable  pass-through  rate
          based on the actual number of days elapsed  during the Accrual  Period
          and an assumed year of 360 days.

          first Payment  Date) based on an assumed year of 360 days,  consisting
          of 12 30-day months.


Assets of the  Trust:  The  assets of the Trust  will  include  (i)  closed-end,

     first  liens and  having  loan-to-value  ratios  of up to 125%  (the  "Home
     Loans", and together with the Home Equity Loans, the "Mortgage Loans").

          In addition to the Mortgage Loans conveyed to the trust on the closing
          date,  the  property  of the trust  will  include  cash on  deposit in

          collections on the mortgage loans.


Pre-Funding Account:  On the Closing Date,  approximately  $136,983,933  will be
     deposited into an account (the "Pre-Funding Account"), which amount will be

     earliest of (i) the date on which the amount on deposit in the  Pre-Funding
     Account  is less  than  $50,000,  (ii)  January  28,  2001  and  (iii)  the
     occurrence of a Servicer default under the Pooling and Servicing  Agreement
     (the "Pre-Funding  Period").  The subsequent Mortgage Loans will conform to
     certain  specified  characteristics.  Amounts on deposit in the Pre-Funding
     Account  will be invested in  permitted  investments  as  specified  in the
     Pooling and Servicing  Agreement.  Any amount  remaining in the Pre-Funding
     Account at the end of the Pre-Funding Period will be used to make principal
     payments on the Class A-1 Certificates through Class A-5 Certificates.

Capitalized Interest  Account:  On the Closing Date, a cash deposit will be made
     from the proceeds of the sale of the  Certificates  into an account held by
     the trustee (the "Capitalized Interest Account"). Amounts on deposit in the
     Capitalized  Interest Account will be withdrawn on each Payment Date during
     the Pre-Funding  Period to cover any shortfall in interest  payments on the
     certificates due to the pre-funding  feature during the pre-funding period.
     Any amounts remaining in the capitalized interest account at the end of the
     pre-funding period will be paid to GMACM.


Payments on the  Certificates:  On each monthly  payment date,  the trustee will
     make  distributions  to  certificateholders.   The  amounts  available  for
     distribution will include:

          o    collections of monthly  payments of principal and interest on the
               mortgage  loans,  including  prepayments  and  other  unscheduled
               collections plus

          o    advances for delinquent payments, if required minus

          o    fees and expenses of the trust,  including  reimbursement  of the
               servicer for advances.

          Payments to  certificateholders  will be made from  amounts  available

          o    Tenth,  to pay the amount  necessary  to  increase  the amount of
               overcollateralization to the required overcollateralization level
               to the Class B certificates, to the extent not distributed to the
               Class A certificates  pursuant to clause seventh above, the Class
               M-1 certificates pursuant to clause eighth above or the Class M-2
               certificates  pursuant to clause ninth above, until the principal
               balance of the Class B  certificates  is reduced to the  required
               principal  balance for the Class B certificates  for that payment
               date;

          o    Eleventh,  to pay to the  trustee any unpaid  expenses  and other
               reimbursable amounts owed to the trustee; and

          o    Twelfth, to pay any remaining amount to the Class SB certificates
               and the Class R certificates.

          Payments of principal on the Class A  certificates  shall be allocated
               as follows:

          o    Payments of principal  shall be distributed  concurrently  to the
               Class A-I group in the  aggregate and the Class A-II group in the
               aggregate,  in each case in proportion  to the  percentage of the
               principal collections derived from the related loan group on each
               payment date,  until the  certificate  principal  balances of the
               Class A-I group certificates or the Class A-II group certificates
               in the aggregate have been reduced to zero.

          o    After  either  the  certificates  in the  Class  A-I group in the
               aggregate  or the  certificates  in the Class  A-II  group in the
               aggregate  are reduced to zero,  all  principal  collections  and
               interest collections received from the related loan group will be
               distributed  to  the  remaining  class  or  classes  of  Class  A
               certificates  to  the  extent   necessary  to  pay  interest  and
               principal due on those classes.

               o    The Class A-I group shall include the Class A-1,  Class A-2,
                    Class A-3, Class A-4 and Class A-5 certificates.

               o    The Class A-II group shall include the Class A-6,  Class A-7
                    and Class A-8 certificates.

          Payments  of  principal   that  are  allocated  to  the   certificates
          representing  the Class A-I group or the Class A-II group will be paid
          sequentially within the respective group of certificates,  which means
          that  principal will not be paid on any class of  certificates  unless
          the principal balance of each class of certificates  within such group
          with a lower numerical  designation  has been reduced to zero,  except
          that  a  special   payment   provision   applies   to  the  Class  A-5
          certificates, as described below.

          Because   principal   payments  on  the  certificates  in  respect  of
          liquidation  loss amounts and  overcollateralization  increase amounts
          will be allocated  between the certificates in the Class A-I group and
          the  certificates  in  the  Class  A-II  group  in  proportion  to the
          principal  collections  received  from the related  group,  and not in
          proportion to the amount of liquidation loss amounts on mortgage loans
          in the related  group or the amount of  overcollateralization  derived
          from that group,  excess  interest  collections  from one group may be
          applied  on  any  payment  date  to  make  principal  payments  to the
          certificates corresponding to the other group.

          For at least three years after the closing date, no principal  will be
          distributed to the Class A-5 certificates unless the principal balance
          of the Class A-1, Class A-2, Class A-3 and the Class A-4  certificates
          has been reduced to zero.  After that date, the Class A-5 certificates
          will  receive  a  portion  of  principal  payments  allocated  to  the
          certificates   in  the  Class  A-I  group  while   other   classes  of
          certificates in the Class A-I group are outstanding.

          For at least three years after the closing date, no principal  will be
          distributed to the Class M  certificates  and the Class B certificates
          unless the principal  balance of all of the Class A  certificates  and
          the Class R certificates has been reduced to zero.


Step-down Date:  The first  payment  date  occurring  after the payment  date in
     October 2003, as to which the aggregate of the certificate  balances of the
     Senior  Certificates  (after  applying  payments  received  in the  related
     Collection  Period)  will be able to be reduced on such  payment date to an
     amount equal to the excess, if any, of (a) the aggregate principal balances
     of the  Mortgage  Loans as of such payment  date (after  applying  payments
     received  in the  related  Collection  Period)  over (b) the greater of (i)
     approximately  [24.70]% of the aggregate principal balances of the Mortgage
     Loans as of the end of the related  Collection Period and (ii) 0.50% of the
     initial Pool Balance;  provided,  however,  that the step-down  date may be
     subject to certain loss and  delinquency  criteria set forth in the pooling
     and servicing agreement.

Servicing Fee:                      The  servicing  fee  to  be  paid  to  the  servicer  as  compensation  for
                                    servicing  the Mortgage  Loans will be 0.50% per annum.  The  servicing fee
                                    will be computed and payable monthly.


Advancing:                          For any  month,  if the  servicer  does  not  receive  the  full  scheduled
                                    payment  on a home  loan,  the  servicer  will  advance  funds to cover the
                                    amount of the scheduled  payment that was not made.  For any month,  if the
                                    servicer  does not receive the full  scheduled  interest  payment on a home
                                    equity  loan,  the  servicer  has the option to advance  funds to cover the
                                    amount of the scheduled  interest  payment that was not made.  The servicer
                                    will be  required  to  advance  delinquent  interest  payments  on the home
                                    equity loans to the extent that the  shortfall  would result in a shortfall
                                    in  the  amount  of  interest   available   to  pay  interest  due  on  the
                                    certificates.  However,  the servicer is only  required to advance funds if
                                    it determines  that the advance will be  recoverable  from future  payments
                                    or collections on that mortgage loan.


Credit Enhancement:                 Credit  enhancement  with respect to the  Certificates  will be provided by
                                    (1) excess interest, (2) overcollateralization and (3) subordination.

                                    Excess Interest:  Because the mortgagors are
                                    expected   to  pay  more   interest  on  the
                                    mortgage  loans  than  is  necessary  to pay
                                    interest on the  certificates,  there may be
                                    excess   interest.   Some  of  this   excess
                                    interest   may  be  used  to   protect   the
                                    certificates  against  some losses by making
                                    an     additional     payment     to     the
                                    certificateholders  up to the  amount of the
                                    losses.

                                    Overcollateralization:  Excess interest that
                                    is not needed to cover  losses  will be used
                                    to make additional principal payments on the
                                    certificates,  until the aggregate principal
                                    balance of the  mortgage  loans  exceeds the
                                    aggregate    principal    amount    of   the
                                    certificates  by a  specified  amount.  This
                                    excess will represent overcollateralization,
                                    which may absorb some losses on the mortgage
                                    loans  if they  are not  covered  by  excess
                                    interest.      If     the      level      of
                                    overcollateralization  falls  below  what is
                                    required,   the  excess  interest  described
                                    above  will be paid to the  certificates  as
                                    principal,   until  the  required  level  of
                                    overcollateralization is reached.

                                    Subordination:  Most losses on the  mortgage
                                    loans will be allocated in full to the first
                                    class listed below with a principal  balance
                                    greater than zero:

o       Class B

o       Class M-2

o       Class M-1

                                    When this occurs,  the principal  balance of
                                    the class to which the loss is  allocated is
                                    reduced,  without a corresponding payment of
                                    principal.

                                    If none of the Class M certificates or Class
                                    B certificates  remain  outstanding,  losses
                                    will  be   allocated   among   the  Class  A
                                    certificates  and the Class R  certificates,
                                    in proportion to their  remaining  principal
                                    balances.


Optional Redemption:  A principal payment may be made to redeem the certificates
     upon the  exercise by the  servicer of its option to purchase  the mortgage
     loans in the trust after the  aggregate  principal  balance of the mortgage
     loans is reduced  to an amount  less than or equal to 10% of the sum of the
     initial  aggregate  principal balance of the mortgage loans and the initial
     amount deposited in the pre-funding  account. The purchase price payable by
     the  servicer  for the  mortgage  loans will be the  aggregate  outstanding
     principal  balance of the mortgage  loans, or the fair market value of real
     estate acquired by foreclosure, plus accrued and unpaid interest thereon at
     the weighted  average of the net loan rates of the mortgage  loans  through
     the day preceding the payment date of this purchase.

Tax  Status:  The  certificates,  other  than  the  Class R  certificates,  will
     represent  ownership  of  regular  interests  in  a  real  estate  mortgage
     investment  conduit and will be treated as  representing  ownership of debt
     for federal  income tax purposes.  For federal  income tax  purposes,  each
     class of Class R certificates  will be the sole residual interest in one of
     the two real estate mortgage investment conduits.

ERISAEligibility:  The Class A Certificates may be purchased by employee benefit
     plans subject to the  requirements of ERISA.  The Class M certificates  and
     the  Class B  certificates  may not be  purchased  by most  such  plans  or
     retirement  accounts,  except  as  may  be  permitted  under  an  exemption
     available to insurance  companies  using  general  accounts or in the event
     that the RFC exemption is amended to permit Class M certificates  and Class
     B  certificates  rated  BBB- or better  to be  purchased  by such  plans or
     retirement accounts.  The Class R Certificates may not be purchased by such
     plans.

SMMEAStatus: The Certificates will not constitute  "mortgage related securities"
     for purposes of SMMEA.
