Please read and understand this entire statement before utilizing the Information. The Information is provided solely by Bear, Stearns & Co. ("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. Offering Documents contain data that is current as of their publication dates and after publication may no longer be complete or current. 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 thereof 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. 2 [ADVANTA LOGO] $[247,500,000] (APPROXIMATE) ADVANTA REVOLVING HOME EQUITY LOAN TRUST 1999-A ADVANTA REVOLVING HOME EQUITY LOAN ASSET-BACKED NOTES, SERIES 1999-A ADVANTA MORTGAGE CONDUIT SERVICES, INC.

EXPECTED SETTLEMENT AND REGISTRATION: On or about May [27], 1999 through DTC, Cedelbank and Euroclear. PAYMENT DATES: The 25th of each month, beginning June 25, 1999. CLASS A VARIABLE RATE NOTES: The Trust will issue variable rate notes ("the Class A Notes") in the aggregate principal balance of $[247,500,000] (the "Original Class A Principal Balance"), collateralized by the Loans. DENOMINATIONS: The Notes will be offered for purchase in minimum denominations of $1,000 and multiples of $1 in excess thereof. LOANS: A pool of adjustable rate home equity revolving credit line loans secured by first or junior mortgages or deeds of trust on residential properties made under certain home equity revolving credit line loan agreements (the "Credit Line Agreements").

Page 3 4 ADVANTA REVOLVING HOME EQUITY LOAN TRUST 1999-A Computational Materials INTEREST ACCRUAL PERIOD: Interest will accrue from the prior Payment Date (or in the case of the first Payment Date, from the Closing Date) through the day preceding the current Payment Date (Actual/360 basis). REMITTANCE PERIOD: As to any Payment Date, the calendar month preceding the month of such Payment Date. RECORD DATE: With respect to any Payment Date, the business day immediately preceding such Payment Date. OPTIONAL REDEMPTION DATE: On the first Payment Date after the aggregate Class A Principal Balance has reduced to an amount less than or equal to 10% of the Original Class A Principal Balance. STEP-UP COUPON: For Payment Dates occurring after the Optional Redemption Date, the spread to LIBOR on the Class A Notes will double. PRICING PREPAYMENT SPEED: 30% CPR, 5% Constant Draw Rate. SUBSEQUENT DRAWS: Any additional balances arising as a result of draws under the Credit Line Agreements ("Additional Balance") subsequent to the Cut-off Date will automatically be assigned to the Trust, and depending on the timing of such draws and the amount of principal collections, may result in a corresponding increase in the Overcollateralization Amount (defined as the excess of (i) the aggregate pool principal balance over (ii) the outstanding Class A Principal Balance). CREDIT ENHANCEMENT: Credit enhancement with respect to the Class A Notes will be provided by (1) Excess Cashflow (as defined on page 7 herein), (2) overcollateralization, and (3) the Ambac Insurance Policy. OVERCOLLATERALIZATION: The Bond Insurer will require that the Overcollateralization Amount be maintained at a certain specified level (the "Specified Overcollateralization Amount"). The Bond Insurer may permit the Specified Overcollateralization Amount to decrease or "step-down" over time, subject to certain floors and triggers. If certain trigger(s) are hit, the specified overcollateralization increases. The Overcollateralization Amount as of the Closing Date is expected to be less than the Specified Overcollateralization Amount, thus requiring an increase in the Overcollateralization Amount on future Payment Dates until it equals the Specified Overcollateralization Amount.

Page 4 5 ADVANTA REVOLVING HOME EQUITY LOAN TRUST 1999-A Computational Materials CLASS A NOTE RATE: The Class A Note Rate for each Interest Accrual Period will generally equal the lesser of: (i) (x) with respect to any Payment Date which occurs on or prior to the Optional Redemption Date, the per annum rate equal to the sum of (a) the London interbank offered rate for one-month Eurodollar deposits appearing on Telerate Screen Page 3750 (LIBOR) as of the second LIBOR Business Day prior to the first day of such Interest Accrual Period (or as of two LIBOR Business Days prior to the Closing Date, in the case of the first Interest Accrual Period) and (b) [__]% and (y) for any Payment Date thereafter, the per annum rate equal to the sum of (a) LIBOR and (b) [2x the pricing spread]% (the rate described in this clause (i), the "Class A Formula Rate") and (ii) (x) the per annum rate equal to (i) the product of (a) 12, and (b) the aggregate amount of interest due on the Loans during the prior Remittance Period, net of the amount of Prepayment Interest Shortfalls, Relief Act Shortfalls, the fee payable to the Master Servicer (the "Servicing Fee"), the fee payable to the Indenture Trustee (the "Indenture Trustee Fee"), the fee payable to the Owner Trustee (the "Owner Trustee Fee") and the premium payable to the Insurer (the "Premium Amount") for the related Remittance Period, divided by (ii) the aggregate principal balance of the Loans as of the beginning of the related Remittance Period, less (y) 0.50% (the rate described in this clause (ii) the "Class A Net Funds Cap Rate"). NET FUNDS CAP CARRY FORWARD: For any Payment Date, if the amount of interest due on the Class A Notes is calculated at the Class A Net Funds Cap Rate, then the difference between the amount of interest due and the amount that would have been due if interest were calculated at the Class A Formula Rate (such difference the "Class A Net Funds Cap Carry Forward Amount") will be payable (together with interest thereon at the Class A Formula Rate) on future Payment Dates to the extent of the funds available therefor as described below under the heading "Cash Flow Waterfall." Payment of such amounts are not covered by the Ambac Insurance Policy.

Page 5 6 ADVANTA REVOLVING HOME EQUITY LOAN TRUST 1999-A Computational Materials PRINCIPAL PAYMENTS FOR CLASS A NOTES: The term of the Class A Notes has been divided into two periods, the Managed Amortization Period and the Rapid Amortization Period. The Managed Amortization Period will commence on June 25, 1999 (the "Initial Payment Date") and will end on the [36]th Payment Date (or, if earlier, the Payment Date immediately following the occurrence of a Rapid Amortization Event). The Rapid Amortization Period will commence on the Payment Date immediately following the end of the Managed Amortization Period and will end on the Payment Date on which the Class A Note Principal Balance has been reduced to zero. On each Payment Date, the holders of the Class A Notes will be entitled to receive the Scheduled Principal Distribution Amount for such Payment Date. The aggregate distributions of principal to the Class A Noteholders will not exceed the Original Class A Principal Balance. On any Payment Date during the Managed Amortization Period, the Scheduled Principal Distribution Amount will equal the excess (but in no event less than $0) of (x) the lesser of (i) the Maximum Principal Payment and (ii) the Net Principal Collections over (y) the Overcollateralization Reduction Amount, if any, with respect to such Payment Date. With respect to any Payment Date, the Maximum Principal Payment will equal [96.75]% (the Fixed Allocation Percentage) of the Principal Collections for the related Remittance Period. With respect to any Payment Date, Net Principal Collections are the excess of (x) Principal Collections for the related Remittance Period over (y) the aggregate principal amount of Additional Balances arising during the related Remittance Period, provided, that in no event will the Net Principal Collections be less than $0 with respect to any Payment Date. On any Payment Date during the Rapid Amortization Period, the Scheduled Principal Distribution Amount will equal the excess (but in no event less than $0) of (x) the Maximum Principal Payment over (y) the Overcollateralization Reduction Amount, if any, with respect to such Payment Date. With respect to any Payment Date, the Overcollateralization Reduction Amount will be the lesser of (i) the excess of (x) the Overcollateralization Amount for such Payment Date (assuming that 100% of the Scheduled Principal Distribution Amount for such Payment Date will be applied as a reduction in the Class A Principal Balance on such Payment Date), over (y) the Specified Overcollateralization Amount for such Payment Date, and (ii) the Scheduled Principal Distribution Amount for such Payment Date (calculated without taking into account any Overcollateralization Reduction Amount for such Payment Date).

Page 6 7 ADVANTA REVOLVING HOME EQUITY LOAN TRUST 1999-A Computational Materials ACCELERATED PRINCIPAL PAYMENTS: The holders of the Class A Notes may receive a payment of Excess Cashflow on any Payment Date, as a payment of principal (any such payment, an Accelerated Principal Payment), for the purpose of increasing the Overcollateralization Amount applicable to such Payment Date. CASH FLOW WATERFALL: On each Payment Date, to the extent of the available funds, the Indenture Trustee will make the following allocations, disbursements and transfers in the following order of priority: 1) Fees due to the Indenture Trustee and Owner Trustee; 2) Premium Amount payable to the Insurer; 3) Interest on the Class A Notes at the Class A Note Rate, together with any unpaid interest from prior Payment Dates; 4) Scheduled Principal Distribution Amount; 5) as a distribution of principal, the Overcollateralization Deficit; 6) any Reimbursement Amount to the Insurer; 7) the Accelerated Principal Payment in satisfaction of the overcollateralization requirements, payable out of Excess Cashflow; 8) any Class A Net Funds Cap Carry-Forward Amount then due; 9) reimbursement to the Master Servicer for any Servicer Advances to the extent not previously reimbursed; and 10) any amount remaining to the Certificateholders. With respect to any Payment Date, the Overcollateralization Deficit will be the amount, if any, by which the current Class A Principal Balance (after taking into account the payment of all principal from sources other than the Policy on such Payment Date), exceeds the aggregate principal balance of the Loans as of such Payment Date. With respect to any Payment Date, the "Excess Cashflow" will be the available funds with respect to such Payment Date remaining after the distribution of the amounts in clauses (1) through (6) above on such Payment Date. SERVICING FEE: 0.50% per annum (the Servicing Fee Rate) on the aggregate principal balances of the Loans ADVANCES: Servicing Advances only (not P&I Advances). TAX STATUS: The Class A Notes will be characterized as debt. ERISA ELIGIBILITY: The Class A Notes are expected to be ERISA eligible. SMMEA ELIGIBILITY: The offered securities will NOT be SMMEA eligible.
