     Section 4.02. Determination of Monthly Interest.

         (a) Subject to Section 4.02(e), the amount of monthly interest ("CLASS
A MONTHLY INTEREST") distributable from the Collection Account with respect to
the Class A Notes on any Payment Date shall be an amount equal to the product of
(i) a fraction, the numerator of which is the actual number of days in the
related Interest Period and the denominator of which is 360, times (ii) the
Class A Note Interest Rate in effect with respect to the related Interest
Period, times (iii) the Class A Note Principal Balance as of the close of
business on the related Record Date (or, with respect to the initial Payment
Date, the Class A Note Initial Principal Balance).

         On the Determination Date preceding each Payment Date, the Servicer
shall determine the excess, if any (the "CLASS A INTEREST SHORTFALL"), of (x)
the Class A Monthly Interest for such Payment Date over (y) the aggregate amount
of funds allocated and available to pay such Class A Monthly Interest on such
Payment Date. If the Class A Interest Shortfall with respect to any Payment Date
is greater than zero, on each subsequent Payment Date until such Class A
Interest Shortfall is fully paid, an additional amount ("CLASS A ADDITIONAL
INTEREST") equal to the product of (i) a fraction, the numerator of which is the
actual number of days in the related Interest Period and the denominator of
which is 360, times (ii) the Class A Note Interest Rate in effect with respect
to the related Interest Period, times (iii) such Class A Interest Shortfall (or
the portion thereof which has not been paid to the Class A Noteholders) shall be
payable as provided herein with respect to the Class A Notes. Notwithstanding
anything to the contrary herein, Class A Additional Interest shall be payable or
distributed to the Class A Noteholders only to the extent permitted by
applicable law.

         (b) Subject to Section 4.02(e), the amount of monthly interest ("CLASS
B MONTHLY INTEREST") distributable from the Collection Account with respect to
the Class B Notes on any Payment Date shall be an amount equal to the product of
(i) a fraction, the numerator of which is the actual number of days in the
related Interest Period and the denominator of which is 360, times (ii) the
Class B Note Interest Rate in effect with respect to the related Interest
Period, times (iii) the Class B Note Principal Balance as of the close of
business on the related Record Date (or, with respect to the initial Payment
Date, the Class B Note Initial Principal Balance).

         On the Determination Date preceding each Payment Date, the Servicer
shall determine the excess, if any (the "CLASS B INTEREST SHORTFALL"), of (x)
the Class B Monthly Interest for such Payment Date over (y) the aggregate amount
of funds allocated and available to pay such Class B Monthly Interest on such
Payment Date. If the Class B Interest Shortfall with respect to any Payment Date
is greater than zero, on each subsequent Payment Date until such Class B
Interest Shortfall is fully paid, an additional amount ("CLASS B ADDITIONAL
INTEREST") equal to the product of (i) a fraction, the numerator of which is the
actual number of days in the related Interest Period and the denominator of
which is 360, times (ii) the Class B Note Interest Rate in effect with respect
to the related Interest Period, times (iii) such Class B Interest Shortfall (or
the portion thereof which has not been paid to the Class B Noteholders) shall be
payable as provided herein with respect to the Class B Notes. Notwithstanding
anything to the contrary herein, Class B Additional Interest shall


                                       19

be payable or distributed to the Class B Noteholders only to the extent
permitted by applicable law.

         (c) Subject to Section 4.02(e), the amount of monthly interest ("CLASS
C MONTHLY INTEREST") distributable from the Collection Account with respect to
the Class C Notes on any Payment Date shall be an amount equal to the product of
(i) a fraction, the numerator of which is the actual number of days in the
related Interest Period and the denominator of which is 360, times (ii) the
Class C Note Interest Rate in effect with respect to the related Interest
Period, times (iii) the Class C Note Principal Balance as of the close of
business on the related Record Date (or, with respect to the initial Payment
Date, the Class C Note Initial Principal Balance).

                  On the Determination Date preceding each Payment Date, the
Servicer shall determine an amount (the "CLASS C INTEREST SHORTFALL") equal to
(x) the aggregate Class C Monthly Interest for such Payment Date minus (y) the
aggregate amount of funds allocated and available to pay such Class C Monthly
Interest on such Payment Date. If the Class C Interest Shortfall with respect to
any Payment Date is greater than zero, on each subsequent Payment Date until
such Class C Interest Shortfall is fully paid, an additional amount ("CLASS C
ADDITIONAL INTEREST") shall be payable as provided herein with respect to the
Class C Notes equal to the product of (i) a fraction, the numerator of which is
the actual number of days in the related Interest Period and the denominator of
which is 360, times (ii) the Class C Note Interest Rate in effect with respect
to the related Interest Period, times (iii) such Class C Interest Shortfall (or
the portion thereof which has not been paid to the Class C Noteholders (after
giving effect to the application of the proceeds of any draw made on the Cash
Collateral Account as provided in Section 4.04(a)(iv) and Section 4.11(c) for
the purpose of paying such amount with respect to such Payment Date)).
Notwithstanding anything to the contrary herein, Class C Additional Interest
shall be payable or distributed to the Class C Noteholders only to the extent
permitted by applicable law.

(i) a fraction, the numerator of which is the actual number of days in the
related Interest Period and the denominator of which is 360, times (ii) the
Class D Note Interest Rate in effect with respect to the related Interest
Period, times (iii) the Class D Note Principal Balance as of the close of
business on the related Record Date (or, with respect to the initial Payment
Date, the Class D Note Initial Principal Balance).

                  On the Determination Date preceding each Payment Date, the
Servicer shall determine an amount (the "CLASS D INTEREST SHORTFALL") equal to
(x) the aggregate Class D Monthly Interest for such Payment Date minus (y) the
aggregate amount of funds allocated and available to pay such Class D Monthly
Interest on such Payment Date. If the Class D Interest Shortfall with respect to
any Payment Date is greater than zero, on each subsequent Payment Date until
such Class D Interest Shortfall is fully paid, an additional amount ("CLASS D
ADDITIONAL INTEREST") shall be payable as provided herein with respect to the
Class D Notes equal to the product of (i) a fraction, the numerator of which is
the actual number of days in the related Interest Period and the denominator of
which is


                                       20
<PAGE>   24
360, times (ii) the Class D Note Interest Rate in effect with respect to the
related Interest Period, times (iii) such Class D Interest Shortfall (or the
portion thereof which has not been paid to the Class D Noteholders (after giving
effect to the application of the proceeds of any draw made on the Cash
Collateral Account as provided in Section 4.04(a)(viii) and Section 4.11(c) for
the purpose of paying such amount with respect to such Payment Date)).
Notwithstanding anything to the contrary herein, Class D Additional Interest
shall be payable or distributed to the Class D Noteholders only to the extent
permitted by applicable law.

         (e) The amount of Class A Monthly Interest, Class B Monthly Interest,
Class C Monthly Interest and Class D Monthly Interest distributable pursuant to
Section 4.02(a), (b), (c) and (d) above on the first Payment Date will equal the
sum of the interest accrued at the applicable rate from the Closing Date through
and including May 20, 2001 based on LIBOR determined on April 11, 2001 and the
interest accrued from May 21, 2001 through and including June 19, 2001 on LIBOR
determined on May 17, 2001.

         (f) The Transferor may change the Class D Margin Percentage with the
prior written consent of each Rating Agency and without the prior consent of any
Noteholder, so long as the Class D Notes are held by the Transferor or an
Affiliate of the Transferor.

     Section 4.03. Determination of Monthly Principal.

                  The amount of monthly principal distributable from the
Collection Account with respect to the Notes on each Payment Date (the "MONTHLY
PRINCIPAL"), beginning with the Payment Date in the month following the month in
which the Controlled Accumulation Period or, if earlier, the Early Amortization
Period, begins, shall be equal to the least of (i) the Available Principal
Collections on deposit in the Collection Account with respect to such Payment
Date, (ii) for each Payment Date during the Controlled Accumulation Period, the

         on each subsequent Payment Date until the Class B Note Principal
         Balance has been paid in full;

                  (iv) during the Early Amortization Period, after the Class A
         Note Principal Balance and the Class B Note Principal Balance have been
         paid in full, an amount equal to the Monthly Principal remaining, if
         any, shall be distributed to the Paying Agent for payment to the Class
         C Noteholders on such Payment Date and on each subsequent Payment Date
         until the Class C Note Principal Balance has been paid in full;

                  (v) during the Early Amortization Period, after the Class A
         Note Principal Balance, the Class B Note Principal Balance and the
         Class C Note Principal Balance have been paid in full, an amount equal
         to the Monthly Principal remaining, if any, shall be distributed to the
         Paying Agent for payment to the Class D Noteholders on such Payment
         Date and on each subsequent Payment Date until the Class D Note
         Principal Balance has been paid in full; and

                  (vi) in the case of each of the Controlled Accumulation Period
         and the Early Amortization Period, the balance of such Available
         Principal Collections remaining after application in accordance with
         clause (i) or (v) above shall be treated as Shared Principal
         Collections and applied in accordance with Section 8.05 of the
         Indenture.

         (d) On the earlier to occur of (i) the first Payment Date during the
Early Amortization Period and (ii) the Expected Final Principal Payment Date,
the Indenture Trustee, acting in accordance with written instructions from the
Servicer, shall withdraw from the Principal Funding Account and distribute to
the Paying Agent for payment to the Class A Noteholders, the Class B
Noteholders, the Class C Noteholders and the Class D Noteholders, the amounts
deposited into the Principal Funding Account pursuant to subsection 4.04(c)(i).

         (e) The Controlled Accumulation Period is scheduled to commence at the
close of business on July 31, 2007; provided, however, that, if the Accumulation
Period Length (determined as described below) is less than 8 months, the date on
which the Controlled Accumulation Period actually commences will be delayed to
the first Business Day of the month that is the number of whole months prior to
the Expected Final Principal Payment Date at least equal to the Accumulation
Period Length and, as a result, the number of Monthly Periods in the Controlled
Accumulation Period will at least equal the Accumulation Period Length. On the
Determination Date immediately preceding the Reserve Account Funding Date, and
each Determination Date thereafter until the Controlled Accumulation Period
begins, the Servicer will determine the "ACCUMULATION PERIOD LENGTH" which will
equal the number of whole months such that the sum of the Accumulation Period
Factors for each month during such period will be equal to or greater than the
Required Accumulation Factor Number; provided, however, that the Accumulation
Period Length will not be


                                       24
<PAGE>   28



determined to be less than one month; provided further, however, that the
determination of the Accumulation Period Length may be changed at any time if
the Rating Agency Condition is satisfied.

         Section 4.05. Investor Charge-Offs. On each Determination Date, the
Servicer shall calculate the Investor Default Amount, if any, for the related
Payment Date. If, on any Payment Date, the Investor Default Amount for such
Payment Date exceeds the amount of Available Finance Charge Collections
allocated with respect thereto pursuant to subsection 4.04(a)(v) with respect to
such Payment Date, the Invested Amount (after giving effect to any reductions
for any Reallocated Principal Collections on such Payment Date) will be reduced
by the amount of such excess, but not by more than the lesser of the Investor
Default Amount and the Invested Amount (after giving effect to any reductions
for any Reallocated Principal Collections on such Payment Date) for such Payment
Date (such reduction, an "INVESTOR CHARGE-OFF").

         Section 4.06. Reallocated Principal Collections. On each Payment Date,
the Servicer shall apply, or shall cause the Indenture Trustee to apply,
Reallocated Principal Collections with respect to such Payment Date, to fund any
deficiency pursuant to and in the priority set forth in subsections 4.04(a)(i),
(ii), (iii) and (iv). On each Payment Date, the Invested Amount shall be reduced
by the amount of Reallocated Principal Collections for such Payment Date.

         Section 4.07. Excess Finance Charge Collections. Series 2001-A shall
be an Excess Allocation Series with respect to Group One only. Subject to
Section 8.08 of the Indenture, Excess Finance Charge Collections with respect to
the Excess Allocation Series in Group One for any Payment Date will be allocated
to Series 2001-A in an amount equal to the product of (x) the aggregate amount
of Excess Finance Charge Collections with respect to all the Excess Allocation
Series in Group One for such Payment Date and (y) a fraction, the numerator of
which is the Finance Charge Shortfall for Series 2001-A for such Payment Date
and the denominator of which is the aggregate amount of Finance Charge
Shortfalls for all the Excess Allocation Series in Group One for such Payment
Date. The "FINANCE CHARGE SHORTFALL" for Series 2001-A for any Payment Date will
be equal to the excess, if any, of (a) the full amount required to be paid,
without duplication, pursuant to subsections 4.04(a)(i) through (viii) on such
Payment Date over (b) the Available Finance Charge Collections with respect to
such Payment Date (excluding any portion thereof attributable to Excess Finance
Charge Collections).

         Section 4.08. Shared Principal Collections.

          Subject to Section 8.05 of the Indenture, Shared Principal Collections
with respect to the Series in Group One for any Payment Date will be allocated
to Series 2001-A in an amount equal to the product of (x) the aggregate amount
of Shared Principal Collections with respect to all Principal Sharing Series in
Group One for such Payment Date and (y) a fraction, the numerator of which is
the Series 2001-A Principal Shortfall for such Payment Date and the denominator
of which is the aggregate amount of Principal Shortfalls for all the Series
which are Principal Sharing Series in Group One for such Payment Date. The
"SERIES 2001-A PRINCIPAL SHORTFALL" will be equal to (a) for any Payment Date
with respect to the Revolving Period or the Early Amortization Period, zero; (b)
for


                                       25
<PAGE>   29
any Payment Date with respect to the Controlled Accumulation Period, the excess,
if any, of the Controlled Deposit Amount with respect to such Payment Date over
the amount of Available Principal Collections for such Payment Date (excluding
any portion thereof attributable to Shared Principal Collections).

         Section 4.09. Principal Funding Account .

         (a) The Indenture Trustee shall establish and maintain with an Eligible

the Investment Earnings, if any, accrued since the preceding Payment Date on
funds on deposit in the Cash Collateral Account shall be retained in the Cash

the aggregate amount required to be distributed pursuant to subsections

Available Finance Charge Collections), the Indenture Trustee, at the written
direction of the Servicer, shall withdraw from the Cash Collateral Account the
amount of such deficiency up to the Available Cash Collateral Account Amount
and, if the Available Cash Collateral Account Amount is less than such

Finance Charge Collections, minus the amount described in clause (d) of the
definition of Available Finance Charge Collections, shall be deposited into the
Cash Collateral Account under the circumstances set forth in subsection
4.04(a)(ix) up to the amount of the Cash Collateral Account Deficiency.

         (g) If on any Payment Date, after giving effect to all withdrawals from
and deposits to the Cash Collateral Account, the amount on deposit in the Cash
Collateral Account would exceed the Required Cash Collateral Account Amount then
in effect, the Indenture Trustee shall, at the written direction of the
Servicer, release such excess to the Transferor. On the date on which each of
the Class C Note Principal Balance and the Class D Note Principal Balance has

Trustee, at the written direction of the Servicer, shall withdraw from the Cash

         Section 4.12 Determination of LIBOR.

         (a) On each LIBOR Determination Date, the Indenture Trustee shall
determine LIBOR on the basis of the rate for deposits in United States dollars
having a maturity of one month commencing on such LIBOR Determination Date which
appears on Telerate Page 3750 as of 11:00 a.m., London time, on such date. If
such rate does not appear on Telerate Page 3750, LIBOR for that LIBOR
Determination Date shall be determined on the basis of the rates at which
deposits in United States dollars are offered by the Reference Banks at
approximately 11:00 a.m., London time, on that day to prime banks in the London
interbank market for a one-month period and in an amount of not less than U.S.
$1,000,000. The Indenture Trustee shall request the principal London office of
each of the Reference Banks to provide a quotation of its rate. If at least two
(2) such quotations are provided, LIBOR for that LIBOR Determination Date shall
be the arithmetic mean of the quotations. If fewer than two (2) quotations are
provided as requested, LIBOR for that LIBOR Determination Date will be the
arithmetic mean of the rates quoted by major banks in New York City, selected by
the Servicer, at approximately 11:00 a.m., New York City time, on that day for
loans in United States dollars to leading European banks for a one-month period
and in an amount of not less than U.S. $1,000,000; provided, that, if the banks
selected by the Servicer are not quoting such rates, LIBOR for that LIBOR
Determination Date will be the same as LIBOR for the immediately preceding LIBOR
Determination Date.

         (b) The Class A Note Interest Rate, the Class B Note Interest Rate, the
Class C Note Interest Rate and the Class D Note Interest Rate applicable to the
then current and the immediately preceding Interest Periods may be obtained by
telephoning the Indenture Trustee at its corporate trust office at (800)
735-7777 or such other telephone number as shall be designated by the Indenture
Trustee for such purpose by prior written notice by the Indenture Trustee to
each Series 2001-A Noteholder from time to time.

         (c) On each LIBOR Determination Date, the Indenture Trustee shall send
to the Transferor by facsimile transmission, notification of LIBOR for the
following Interest Period.

         Section 4.13. Investment Instructions. Any investment instructions
required to be given to the Indenture Trustee pursuant to the terms hereof must
be given to the Indenture Trustee no later than 11:00 a.m., New York City time,
on the date such investment is to be made. In the event the Indenture Trustee
receives such investment instruction later than such time, the Indenture Trustee
may, but shall have no obligation to, make such investment. In the event the
Indenture Trustee is unable to make an investment required in an investment
instruction received by the Indenture Trustee after 11:00 a.m., New York City
time, on such day, such investment shall be made by the Indenture Trustee on the
next succeeding Business Day. In no event shall the Indenture Trustee be liable
for any investment not made pursuant to investment instructions received after
11:00 a.m., New York City time, on the day such investment is requested to be
made.

                            Miscellaneous Provisions

         Section 8.01. Ratification of Indenture. As supplemented by this
Indenture Supplement, the Indenture is in all respects ratified and confirmed
and the Indenture as so supplemented by this Indenture Supplement shall be read,
taken and construed as one and the same instrument.

         Section 8.02. Form of Delivery of the Series 2001-A Notes.

          The Class A Notes, the Class B Notes and the Class C Notes shall be
Book-Entry Notes and shall be delivered as Registered Notes as provided in
Section 2.01 of the Indenture in substantially the form of Exhibit A hereto.

         Section 8.03. Additional Requirements for Registration of and
Limitations on Transfer and Exchange of Class D Notes.

         (a) (i) Registration of transfer of the Class D Notes shall be effected
only if such transfer is made pursuant to an effective registration statement
under the Securities Act, or is exempt from the registration requirements under
the Securities Act. In the event that registration of a transfer is to be made
in reliance upon an exemption from the registration requirements under the
Securities Act, the transferor or the transferee shall deliver, at its expense,
to the Transferor, the Servicer and the Indenture Trustee, either (A) an
investment letter from the transferee, substantially in the form of the
investment and ERISA representation letter attached hereto as Exhibit E-1, or
(B) an Opinion of Counsel satisfactory to the Transferor, the Servicer and the
Indenture Trustee to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Issuer, the Transferor, the Servicer, the Seller, the Indenture
Trustee or the Transfer Agent and Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such transfer from the Noteholder desiring to effect such transfer and/or such
Noteholder's prospective transferee on which such Opinion of Counsel is based.
None of the Issuer, the Transferor, the Servicer, the Seller, the Indenture
Trustee or the Transfer Agent and Registrar is obligated to register or qualify
the Class D Notes under the Securities Act or any other securities law or to
take any action not otherwise required under this Indenture Supplement or the
Indenture to permit the transfer of the Class D Notes without registration or
qualification. Any Class D Noteholder desiring to effect a transfer of
unregistered Class D Notes shall, and does hereby agree to, indemnify the
Issuer, the Transferor (unless the transferor of the Class D Notes is the
Transferor), the Servicer, the Seller, the Indenture Trustee and the Transfer
Agent and Registrar against any liability that may result if the transfer is not
exempt from such registration or qualification or is not made in accordance with
such federal and state laws and no registration of transfer shall be made until
such letter is so delivered.

         (b) Class D Notes issued upon registration or transfer of, or Class D
Notes issued in exchange for Class D Notes shall bear the restrictive legend
regarding securities laws contained in the form of the Class D Note attached as
Exhibit A-4 hereto, unless the Transferor, the Servicer, the Indenture Trustee
and the Transfer Agent and Registrar receive an Opinion of Counsel, satisfactory


                                       40
<PAGE>   44
to each of them, to the effect that such legend may be removed or modified.

         (c) Registration of transfer of Class D Notes shall be effected only if
the transferee has executed and delivered a certification in the form and
substance attached hereto as Exhibit E-2 to the effect that either (i) the
transferee is not (A) an employee benefit plan (as defined in Section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) that
is subject to the provisions of Title I of ERISA or (B) a plan (as defined in
Section 4975(e)(1) of the Code (the "Code")) that is subject to Section 4975 of
the Code (each of the foregoing, a "Benefit Plan"), and is not acting on behalf
of or investing the assets of a Benefit Plan, or (ii) that the transferee's
acquisition and continued holding of the applicable Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption or other
applicable statutory or regulatory exemption.

         (d) If so requested by the Transferor, the Indenture Trustee will make
available to any prospective purchaser of Class D Notes who so requests, a copy
of a letter provided to the Trustee by or on behalf of the Transferor relating
to the transferability of any Series or Class to a Benefit Plan.

         Section 8.04. Amendment. This Indenture Supplement may be amended only
in accordance with the provisions set forth in Sections 10.01 and 10.02 of the
Indenture.

         Section 8.05. Counterparts. This Indenture Supplement may be executed
in two or more counterparts, and by different parties on separate counterparts,
each of which shall be an original, but all of which shall constitute one and
the same instrument.

         Section 8.06. GOVERNING LAW. THIS INDENTURE SUPPLEMENT SHALL BE
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REFERENCE TO ITS CONFLICT OF LAWS PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH
LAWS.

         Section 8.07. Limitation of Liability. Notwithstanding any other
provision herein or elsewhere, this Agreement has been executed and delivered by
Wilmington Trust Company, not in its individual capacity, but solely in its
capacity as Owner Trustee of the Trust, in no event shall (i) Wilmington Trust
Company in its individual capacity, (ii) any owner of a beneficial interest in
the Trust or (iii) any partner, owner, beneficiary, agent, officer, director,
employee or agent of the Owner Trustee in its individual capacity, any holder of
a beneficial interest in the Trust, the Owner Trustee or of any successor or
assign of the Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed (it being understood that the Owner Trustee has
no such obligations in its individual capacity), have any liability in respect
of the representations, warranties, or obligations of the Trust hereunder or
under any other document, as to all of which recourse shall be had solely to the
assets of the Trust, and for all purposes of this Agreement and each other
document, the Owner Trustee (as such or in its individual capacity) shall be
subject to, and entitled to the benefits of, the terms and provisions of the
Trust Agreement.

                            CLASS A ASSET BACKED NOTE

                         Summary of Terms and Conditions

         This Class A Note is one of a duly authorized issue of Notes of the
Issuer, designated as Advanta Business Card Master Trust, Series 2001-A (the
"SERIES 2001-A NOTES"), issued under a Master Indenture dated as of August 1,
2000 (the "MASTER INDENTURE"), between the Issuer and Bankers Trust Company, as
indenture trustee (the "INDENTURE TRUSTEE"), as supplemented by the Indenture
Supplement dated as of April 1, 2001 (the "INDENTURE SUPPLEMENT"), and
representing the right to receive certain payments from the Issuer. The term
"Indenture," unless the context otherwise requires, refers to the Master
Indenture as supplemented by the Indenture Supplement. The Notes are subject to
all of the terms of the Indenture. All terms used in this Note that are defined
in the Indenture shall have the meanings assigned to them in or pursuant to the
Indenture. In the event of any conflict or inconsistency between the Indenture
and this Note, the Indenture shall control.

         The Class B Notes, the Class C Notes and the Class D Notes will also be
issued under the Indenture.

         The Noteholder, by its acceptance of this Note, agrees that it will
look solely to the property of the Trust allocated to the payment of this Note
for payment hereunder and that the Indenture Trustee is not liable to the
Noteholders for any amount payable under the Note or the Indenture or, except as
expressly provided in the Indenture, subject to any liability under the
Indenture.

         This Note does not purport to summarize the Indenture and reference is
made to the Indenture for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Indenture Trustee.

         The Class A Note Initial Principal Balance is $240,000,000. The Class A
Note Principal Balance on any date of determination will be an amount equal to
(a) the Class A Note Initial Principal Balance, minus (b) the aggregate amount
of principal payments made to the Class A Noteholders on or prior to such date.

         The Expected Final Principal Payment Date is the April 2008 Payment
Date, but principal with respect to the Class A Notes may be paid earlier or
later under certain circumstances described in the Indenture. If for one or more
months during the Controlled Accumulation Period there are not sufficient funds
to deposit into the Principal Funding Account the Controlled Deposit Amount,
then to the extent that excess funds are not available on subsequent Payment
Dates with respect to the Controlled Accumulation Period to make up for such
shortfalls, the final payment of principal of the Notes will occur later than
the Expected Final Principal Payment Date. Payments of principal of the Notes
shall be payable in accordance with the provisions of the Indenture.


                                 Exhibit A-1-5
<PAGE>   52
         Subject to the terms and conditions of the Indenture, the Transferor
may, from time to time, direct the Owner Trustee, on behalf of the Trust, to
issue one or more new Series of Notes.

         On each Payment Date, the Paying Agent shall distribute to each Class A
Noteholder of record on the related Record Date (except for the final payment in
respect of this Class A Note) such Class A Noteholder's pro rata share of the
amounts held by the Paying Agent that are allocated and available on such
Payment Date to pay interest and principal on the Class A Notes pursuant to the
Indenture Supplement. Except as provided in the Indenture with respect to a
final payment, payments to Series 2001-A Noteholders shall be made by (i) check
mailed to each Series 2001-A Noteholder (at such Noteholder's address as it
appears in the Note Register), except that with respect to any Series 2001-A
Notes registered in the name of the nominee of a Clearing Agency, such payment
shall be made in immediately available funds and (ii) without presentation or
surrender of any Series 2001-A Note or the making of any notation thereon. Final
payment of this Class A Note will be made only upon presentation and surrender
of this Class A Note at the office or agency specified in the notice of final
payment delivered by the Indenture Trustee to the Series 2001-A Noteholders in
accordance with the Indenture.

         On any day occurring on or after the date on which the outstanding
principal balance of the Series 2001-A Notes is reduced to 10% or less of the
initial outstanding principal balance of the Series 2001-A Notes, the Servicer
shall have the option to redeem the Series 2001-A Notes, at a purchase price
equal to (i) if such day is a Payment Date, the Reassignment Amount for such
Payment Date or (ii) if such day is not a Payment Date, the Reassignment Amount
for the Payment Date following such day.

         THIS CLASS A NOTE DOES NOT REPRESENT AN OBLIGATION OF, OR AN INTEREST
IN, THE TRANSFEROR, ADVANTA BANK CORP., ADVANTA CORP., OR ANY AFFILIATE OF ANY
OF THEM AND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE
CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.

         Each Noteholder, by accepting a Note, hereby covenants and agrees that
it will not at any time institute against the Issuer or the Transferor, or join
in instituting against the Issuer or the Transferor, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law.

         Except as otherwise provided in the Indenture Supplement, the Class A
Notes are issuable only in minimum denominations of $1,000 and integral
multiples of $1,000. The transfer of this Class A Note shall be registered in
the Note Register upon surrender of this Class A Note for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar
accompanied by a written instrument of transfer, in a form satisfactory to the
Indenture Trustee or the Transfer Agent and Registrar, duly executed by the
Class A Noteholder or such Class A Noteholder's attorney, and duly authorized in
writing with such signature guaranteed, and thereupon one or more new Class A
Notes in any authorized denominations of like aggregate principal amount will be
issued to the


                                 Exhibit A-1-6
<PAGE>   53
designated transferee or transferees.

         As provided in the Indenture and subject to certain limitations therein
set forth, Class A Notes are exchangeable for new Class A Notes in any
authorized denominations and of like aggregate principal amount, upon surrender
of such Notes to be exchanged at the office or agency of the Transfer Agent and
Registrar. No service charge may be imposed for any such exchange but the Issuer
or Transfer Agent and Registrar may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.

         The Issuer, the Transferor, the Indenture Trustee and any agent of the
Issuer, the Transferor or the Indenture Trustee shall treat the person in whose
name this Class A Note is registered as the owner hereof for all purposes, and
neither the Issuer, the Transferor, the Indenture Trustee nor any agent of the
Issuer, the Transferor or the Indenture Trustee shall be affected by notice to
the contrary.

         THIS CLASS A NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAWS PROVISIONS, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

                         Summary of Terms and Conditions

         This Class B Note is one of a duly authorized issue of Notes of the
Issuer, designated as Advanta Business Card Master Trust, Series 2001-A (the
"SERIES 2001-A NOTES"), issued under a Master Indenture dated as of August 1,
2000 (the "MASTER INDENTURE"), between the Issuer and Bankers Trust Company, as
indenture trustee (the "INDENTURE TRUSTEE"), as supplemented by the Indenture
Supplement dated as of April 1, 2001 (the "INDENTURE SUPPLEMENT"), and
representing the right to receive certain payments from the Issuer. The term
"Indenture," unless the context otherwise requires, refers to the Master
Indenture as supplemented by the Indenture Supplement. The Notes are subject to
all of the terms of the Indenture. All terms used in this Note that are defined
in the Indenture shall have the meanings assigned to them in or pursuant to the
Indenture. In the event of any conflict or inconsistency between the Indenture
and this Note, the Indenture shall control.

         The Class A Notes, the Class C Notes and the Class D Notes will also be
issued under the Indenture.

         The Noteholder, by its acceptance of this Note, agrees that it will
look solely to the property of the Trust allocated to the payment of this Note
for payment hereunder and that the Indenture Trustee is not liable to the
Noteholders for any amount payable under the Note or the Indenture or, except as
expressly provided in the Indenture, subject to any liability under the
Indenture.

         This Note does not purport to summarize the Indenture and reference is
made to the Indenture for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Indenture Trustee.

         The Class B Note Initial Principal Balance is $28,500,000.

         The Class B Note Principal Balance on any date of determination will be
an amount equal to (a) the Class B Note Initial Principal Balance, minus (b) the
aggregate amount of principal payments made to the Class B Noteholders on or
prior to such date.

         The Expected Final Principal Payment Date is the April 2008 Payment
Date, but principal with respect to the Class B Notes may be paid earlier or
later under certain circumstances described in the Indenture. If for one or more
months during the Controlled Accumulation Period there are not sufficient funds
to deposit into the Principal Funding Account the Controlled Deposit Amount,
then to the extent that excess funds are not available on subsequent Payment
Dates with respect to the Controlled Accumulation Period to make up for such
shortfalls, the final payment of principal of the Notes will occur later than
the Expected Final Principal Payment Date. Payments of principal of the Notes
shall be payable in accordance with the provisions of the Indenture.

Noteholder of record on the related Record Date (except for the final payment in
respect of this Class B Note) such Class B Noteholder's pro rata share of the
amounts held by the Paying Agent that are allocated and available on such
Payment Date to pay interest and principal on the Class B Notes pursuant to the
Indenture Supplement. Except as provided in the Indenture with respect to a
final payment, payments to Series 2001-A Noteholders shall be made by (i) check
mailed to each Series 2001-A Noteholder (at such Noteholder's address as it
appears in the Note Register), except that with respect to any Series 2001-A
Notes registered in the name of the nominee of a Clearing Agency, such payment

                            CLASS C ASSET BACKED NOTE

                         Summary of Terms and Conditions

         This Class C Note is one of a duly authorized issue of Notes of the
Issuer, designated as Advanta Business Card Master Trust, Series 2001-A (the
"SERIES 2001-A NOTES"), issued under a Master Indenture dated as of August 1,
2000 (the "MASTER INDENTURE"), between the Issuer and Bankers Trust Company, as
indenture trustee (the "INDENTURE TRUSTEE"), as supplemented by the Indenture
Supplement dated as of April 1, 2001 (the "INDENTURE SUPPLEMENT"), and
representing the right to receive certain payments from the Issuer. The term
"Indenture," unless the context otherwise requires, refers to the Master
Indenture as supplemented by the Indenture Supplement. The Notes are subject to
all of the terms of the Indenture. All terms used in this Note that are defined
in the Indenture shall have the meanings assigned to them in or pursuant to the
Indenture. In the event of any conflict or inconsistency between the Indenture
and this Note, the Indenture shall control.

         The Class A Notes, the Class B Notes and the Class D Notes will also be
issued under the Indenture.

         The Noteholder, by its acceptance of this Note, agrees that it will
look solely to the property of the Trust allocated to the payment of this Note
for payment hereunder and that the Indenture Trustee is not liable to the
Noteholders for any amount payable under the Note or the Indenture or, except as
expressly provided in the Indenture, subject to any liability under the
Indenture.

         This Note does not purport to summarize the Indenture and reference is
made to the Indenture for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Indenture Trustee.

         The Class C Note Initial Principal Balance is $21,000,000.

         The Class C Note Principal Balance on any date of determination will be
an amount equal to (a) the Class C Note Initial Principal Balance, minus (b) the
aggregate amount of principal payments made to the Class C Noteholders on or
prior to such date.

         The Expected Final Principal Payment Date is the April 2008 Payment
Date, but principal with respect to the Class C Notes may be paid earlier or
later under certain circumstances described in the Indenture. If for one or more
months during the Controlled Accumulation Period there are not sufficient funds
to deposit into the Principal Funding Account the Controlled Deposit Amount,
then to the extent that excess funds are not available on subsequent Payment
Dates with respect to the Controlled Accumulation Period to make up for such
shortfalls, the final payment of principal of the Notes will occur later than
the Expected Final Principal Payment Date. Payments of principal of the Notes
shall be payable in accordance with the provisions of the Indenture.

                                 Exhibit A-3-5
<PAGE>   68

         Subject to the terms and conditions of the Indenture, the Transferor
may, from time to time, direct the Owner Trustee, on behalf of the Trust, to
issue one or more new Series of Notes.

         On each Payment Date, the Paying Agent shall distribute to each Class C
Noteholder of record on the related Record Date (except for the final payment in
respect of this Class C Note) such Class C Noteholder's pro rata share of the
amounts held by the Paying Agent that are allocated and available on such
Payment Date to pay interest and principal on the Class C Notes pursuant to the
Indenture Supplement. Except as provided in the Indenture with respect to a
final payment, payments to Series 2001-A Noteholders shall be made by (i) check
mailed to each Series 2001-A Noteholder (at such Noteholder's address as it
appears in the Note Register), except that with respect to any Series 2001-A
Notes registered in the name of the nominee of a Clearing Agency, such payment
shall be made in immediately available funds and (ii) without presentation or
surrender of any Series 2001-A Note or the making of any notation thereon. Final
payment of this Class C Note will be made only upon presentation and surrender
of this Class C Note at the office or agency specified in the notice of final
payment delivered by the Indenture Trustee to the Series 2001-A Noteholders in
accordance with the Indenture.

         On any day occurring on or after the date on which the outstanding
principal balance of the Series 2001-A Notes is reduced to 10% or less of the
initial outstanding principal balance of the Series 2001-A Notes, the Servicer
shall have the option to redeem the Series 2001-A Notes, at a purchase price
equal to (i) if such day is a Payment Date, the Reassignment Amount for such
Payment Date or (ii) if such day is not a Payment Date, the Reassignment Amount
for the Payment Date following such day.

         THIS CLASS C NOTE DOES NOT REPRESENT AN OBLIGATION OF, OR AN INTEREST
IN, THE TRANSFEROR, ADVANTA BANK CORP., ADVANTA CORP., OR ANY AFFILIATE OF ANY
OF THEM AND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE
CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.

         Each Noteholder, by accepting a Note, hereby covenants and agrees that
it will not at any time institute against the Issuer or the Transferor, or join
in instituting against the Issuer or the Transferor, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law.


         Except as otherwise provided in the Indenture Supplement, the Class C
Notes are issuable only in minimum denominations of $1,000 and integral
multiples of $1,000. The transfer of this Class C Note shall be registered in
the Note Register upon surrender of this Class C Note for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar
accompanied by a written instrument of transfer, in a form satisfactory to the
Indenture Trustee or the Transfer Agent and Registrar, duly executed by the
Class C Noteholder or such Class C Noteholder's attorney, and duly authorized in
writing with such signature guaranteed, and thereupon one or more new Class C
Notes in any authorized denominations of like aggregate principal amount will be
issued to the

                                 Exhibit A-3-6
<PAGE>   69

designated transferee or transferees.

         As provided in the Indenture and subject to certain limitations therein
set forth, Class C Notes are exchangeable for new Class C Notes in any
authorized denominations and of like aggregate principal amount, upon surrender
of such Notes to be exchanged at the office or agency of the Transfer Agent and
Registrar. No service charge may be imposed for any such exchange but the Issuer
or Transfer Agent and Registrar may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.

         The Issuer, the Transferor, the Indenture Trustee and any agent of the
Issuer, the Transferor or the Indenture Trustee shall treat the person in whose
name this Class C Note is registered as the owner hereof for all purposes, and
neither the Issuer, the Transferor, the Indenture Trustee nor any agent of the
Issuer, the Transferor or the Indenture Trustee shall be affected by notice to
the contrary.

STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAWS PROVISIONS, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN

         The Noteholder, by its acceptance of this Note, agrees that it will
look solely to the property of the Trust allocated to the payment of this Note
for payment hereunder and that the Indenture Trustee is not liable to the
Noteholders for any amount payable under the Note or the Indenture or, except as
expressly provided in the Indenture, subject to any liability under the
Indenture.

         This Note does not purport to summarize the Indenture and reference is
made to the Indenture for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced thereby, and the rights, duties and
immunities of the Indenture Trustee.

         The Class D Note Initial Principal Balance is $10,500,000.

         The Class D Note Principal Balance on any date of determination will be
an amount equal to (a) the Class D Note Initial Principal Balance, minus (b) the
aggregate amount of principal payments made to the Class D Noteholders on or
prior to such date.

         The Expected Final Principal Payment Date is the April 2008 Payment
Date, but principal with respect to the Class D Notes may be paid earlier or
later under certain circumstances described in the Indenture. If for one or more
months during the Controlled Accumulation Period there are not sufficient funds
to deposit into the Principal Funding Account the Controlled Deposit Amount,
then to the extent that excess funds are not available on subsequent Payment
Dates with respect to the Controlled Accumulation Period to make up for such
shortfalls, the final payment of principal of the Notes will occur later than
the Expected Final Principal Payment Date. Payments of principal of the Notes
shall be payable in accordance with the provisions of the Indenture.

                                 Exhibit A-4-5
<PAGE>   76

         Subject to the terms and conditions of the Indenture, the Transferor
may, from time to time, direct the Owner Trustee, on behalf of the Trust, to
issue one or more new Series of Notes.

         On each Payment Date, the Paying Agent shall distribute to each Class D
Noteholder of record on the related Record Date (except for the final payment in
respect of this Class D Note) such Class D Noteholder's pro rata share of the
amounts held by the Paying Agent that are allocated and available on such
Payment Date to pay interest and principal on the Class D Notes pursuant to the
Indenture Supplement. Except as provided in the Indenture with respect to a
final payment, payments to Series 2001-A Noteholders shall be made by (i) check
mailed to each Series 2001-A Noteholder (at such Noteholder's address as it
appears in the Note Register), except that with respect to any Series 2001-A
Notes registered in the name of the nominee of a Clearing Agency, such payment
shall be made in immediately available funds and (ii) without presentation or
surrender of any Series 2001-A Note or the making of any notation thereon. Final
payment of this Class D Note will be made only upon presentation and surrender
of this Class D Note at the office or agency specified in the notice of final
payment delivered by the Indenture Trustee to the Series 2001-A Noteholders in
accordance with the Indenture.

         On any day occurring on or after the date on which the outstanding
principal balance of the Series 2001-A Notes is reduced to 10% or less of the
initial outstanding principal balance of the Series 2001-A Notes, the Servicer
shall have the option to redeem the Series 2001-A Notes, at a purchase price
equal to (i) if such day is a Payment Date, the Reassignment Amount for such
Payment Date or (ii) if such day is not a Payment Date, the Reassignment Amount
for the Payment Date following such day.

         THIS CLASS D NOTE DOES NOT REPRESENT AN OBLIGATION OF, OR AN INTEREST
IN, THE TRANSFEROR, ADVANTA BANK CORP., ADVANTA CORP., OR ANY AFFILIATE OF ANY
OF THEM AND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE
CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.

         Each Noteholder, by accepting a Note, hereby covenants and agrees that
it will not at any time institute against the Issuer or the Transferor, or join
in instituting against the Issuer or the Transferor, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law.

         Except as otherwise provided in the Indenture Supplement, the Class D
Notes are issuable only in minimum denominations of $1,000 and integral
multiples of $1,000. The transfer of this Class D Note shall be registered in
the Note Register upon surrender of this Class D Note for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar
accompanied by a written instrument of transfer, in a form satisfactory to the
Indenture Trustee or the Transfer Agent and Registrar, duly executed by the
Class D Noteholder or such Class D Noteholder's attorney, and duly authorized in
writing with such signature guaranteed, and thereupon one or more new Class D
Notes in any authorized denominations of like aggregate principal amount will be
issued to the

                                 Exhibit A-4-6
<PAGE>   77
designated transferee or transferees.

         As provided in the Indenture and subject to certain limitations therein
set forth, Class D Notes are exchangeable for new Class D Notes in any
authorized denominations and of like aggregate principal amount, upon surrender
of such Notes to be exchanged at the office or agency of the Transfer Agent and
Registrar. No service charge may be imposed for any such exchange but the Issuer
or Transfer Agent and Registrar may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection
therewith.

         Registration of transfer of Class D Notes shall be effected only if the
transferee has executed and delivered a certification in the form and substance
attached to the Indenture Supplement as Exhibit E-2 to the effect that either
(i) the transferee is not (A) an employee benefit plan (as defined in Section
3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) that is subject to the provisions of Title I of ERISA or (B) a plan
(as defined in Section 4975(e)(1) of the Code (the "Code")) that is subject to
Section 4975 of the Code (each of the foregoing, a "Benefit Plan"), and is not
acting on behalf of or investing the assets of a Benefit Plan, or (ii) that the
transferee's acquisition and continued holding of the Note will be covered by a
U.S. Department of Labor Prohibited Transaction Class Exemption or other
applicable statutory or regulatory exemption.

         The Issuer, the Transferor, the Indenture Trustee and any agent of the
Issuer, the Transferor or the Indenture Trustee shall treat the person in whose
name this Class D Note is registered as the owner hereof for all purposes, and
neither the Issuer, the Transferor, the Indenture Trustee nor any agent of the
Issuer, the Transferor or the Indenture Trustee shall be affected by notice to
the contrary.

         THIS CLASS D NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAWS PROVISIONS, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

                  BUSINESS CARD MASTER TRUST, CLASS D ASSET BACKED NOTES,
                  SERIES 2001-A

Dear Sirs:

         In connection with our purchase of the above Class D Asset Backed Notes
(the "Notes") we confirm that:

         1. we understand that the Notes have not and are not being registered
under the Securities Act of 1933, as amended (the "Securities Act"), and are
being sold to us in a transaction that is exempt from the registration
requirements of the Securities Act;

         2. any information we desire concerning the Notes or any other matter
relevant to our decision to purchase the Notes is or has been made available to
us;

         3. we have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of an investment in
the Notes, and we (and any account for which we are purchasing under paragraph
(iv) below) are able to bear the economic risk of an investment in the Notes; we
(and any account for which we are purchasing under paragraph (iv) below) are an
"accredited investor" (as such term is defined in Rule 501(a)(1), (2) or (3) of
Regulation D under the Securities Act); and we are not, and none of such
accounts is, a Benefit Plan;

         4. we are acquiring the Notes for our own account or for accounts as to
which we exercise sole investment discretion and not with a view to any
distribution of the Notes, subject nevertheless to the understanding that the
disposition of our property shall at all times be and remain within our control;


         5. we agree that the Notes must be held indefinitely by us unless
subsequently registered

                                 Exhibit E-1-1
<PAGE>   88
under the Securities Act or an exemption is available from any registration
requirements of the Securities Act and any applicable state securities law;

         5. we agree that in the event that at some future time we wish to
dispose of or exchange any of the Notes (such disposition or exchange not being
currently foreseen or contemplated), we will not transfer or exchange any of the
Notes unless:

                  (a)(i) the sale is to an Eligible Purchaser (as defined
         below), (ii) a letter to substantially the same effect as paragraphs
         (1), (2), (3), (4), (5) and (6) of this letter is executed promptly by
         the purchaser and (iii) all offers or solicitations in connection with
         the sale, whether directly or through any agent acting on our behalf,
         are limited only to Eligible Purchasers and are not made by means of
         any form of general solicitation or general advertising whatsoever; or

                  (B) the Notes are transferred pursuant to Rule 144 under the
         Securities Act by us after we have held them for more than three years;
         or

                  (C) the Notes are sold in any other transaction that does not
         require registration under the Securities Act and, if the Transferor,
         the Servicer, the Seller, the Indenture Trustee or the Transfer Agent
         and Registrar so requests, we therefore have furnished to such party an
         Opinion of Counsel satisfactory to such party, in form and substance
         satisfactory to the Indenture Trustee, to such effect; or

                  (D) the Notes are transferred pursuant to an exception from
         the registration requirements of the Securities Act under Rule 144A
         under the Securities Act; and

7.       we understand that the Notes will bear a legend to substantially the
         following effect:

         "THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED (THE "SECURITIES ACT"). NEITHER THIS NOTE NOR ANY INTEREST
         HEREIN MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
         COMPLIANCE WITH THE REGISTRATION PROVISIONS OF THE SECURITIES ACT AND
         ANY APPLICABLE PROVISIONS OF ANY STATE BLUE SKY OR SECURITIES LAWS OR
         PURSUANT TO AN AVAILABLE EXEMPTION FROM SUCH PROVISIONS. THE TRANSFER
         OF THIS NOTE IS SUBJECT TO CERTAIN CONDITIONS SET FORTH IN THE
         INDENTURE SUPPLEMENT REFERRED TO HEREIN."

         "THIS NOTE MAY NOT BE ACQUIRED BY OR FOR THE ACCOUNT OF A BENEFIT PLAN
         EXCEPT IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH HEREIN AND IN THE
         INDENTURE SUPPLEMENT."

                                 Exhibit E-1-2
<PAGE>   89

Any portion of this legend may be removed or modified if the Transferor, the
Servicer, the Seller, the Indenture Trustee and the Transfer Agent and Registrar
have received an Opinion of Counsel, in form and substance satisfactory to them,
to the effect that such paragraph may be removed or modified.

         "Eligible Purchaser" means either an Eligible Dealer or a corporation,
partnership or other entity which we have reasonable grounds to believe and do
believe can make representations with respect to itself to substantially the
same effect as the representations set forth herein. "Eligible Dealer" means any

whose underlying assets include plan assets by reason of a plan's investment in
such entity. Capitalized terms used but not defined herein shall have the
meanings given to such terms in the Indenture Supplement (the "Indenture
