TITLE OF SECURITIES:                   Advanta Mortgage Loan Trust 1999-1, Mortgage Loan Asset-Backed Certificates, Series
                                       1999-1 (collectively, the "Certificates").

DESCRIPTION OF TRANSACTION:            This MBIA-wrapped transaction has six fixed rate certificates (Classes A-1 to A-6)
                                       and one floating rate certificate (Class A-7) and is supported by two groups of
                                       mortgage loans. Classes A-1 to A-6 are primarily supported by cash flows from a
                                       group of fixed rate first and junior lien mortgages. Class A-7 is primarily
                                       supported by a group of adjustable rate first lien mortgages. Each class will also
                                       have the benefit of limited cross-collateralization from the other group of
                                       mortgage loans.

MORTGAGE LOANS:                        Both of the fixed and adjustable rate mortgage loans are secured by single-family
                                       residences that may be detached, part of a two- to four-family dwelling, a
                                       condominium unit or a unit in a planned unit development. The actual mortgage loans
                                       in each group as of the closing date will represent approximately $350,000,000 in
                                       each of the fixed rate group and ARM group. It is anticipated that at the end of
                                       the pre-funding period, there will be approximately $400,000,000 in each of the
                                       fixed rate group and ARM group. As of the Statistical Calculation Date, the
                                       principal balance of the mortgage loans is expected to be $313,282,466 for the
                                       fixed rate group and $349,979,204 for the ARM group.

                                       may be applied to the purchase of additional mortgage loans for assignment to the
                                       fixed rate group and approximately $50 million, which may be applied to the

                                       ARM available funds cap rate. To the extent that a Supplemental Interest Amount
                                       exists and remains unpaid it will carry-forward, accruing interest at the Class A-7
                                       Certificate pass-through rate, and be paid when possible. If an optional
                                       termination is exercised any remaining Supplemental Interest Amount might not be
                                       paid in full.

                                       Any Supplemental Interest Amount is not guaranteed by MBIA and the
                                       ratings do not address the likelihood of receiving any such amounts.

PRINCIPAL DISTRIBUTION:                AMOUNTS DISTRIBUTABLE TO HOLDERS OF THE CERTIFICATES SHALL BE ALLOCATED ON EACH
