         REVOLVING LIQUIDITY NOTE AGREEMENT (this "Agreement") dated as of July
7, 2005, by and between BANC OF AMERICA SECURITIES AUTO TRUST 2005-WF1, a
Delaware statutory trust, as issuer (the "Issuer") of the revolving liquidity
note (the "Revolving Liquidity Note") issued hereunder, and BANK OF AMERICA,
NATIONAL ASSOCIATION, a Delaware corporation ("BANA"), as the initial holder of
the Revolving Liquidity Note.

                              W I T N E S S E T H:

         WHEREAS the Issuer is issuing Class A-1 3.50545% Auto Loan Asset Backed
Notes (the "Class A-1 Notes"), Class A-2 3.89% Auto Loan Asset Backed Notes (the
"Class A-2 Notes"), Class A-3 3.99% Auto Loan Asset Backed Notes (the "Class A-3
Notes"), the Class A-4 4.08% Auto Loan Asset Backed Notes (the "Class A-4
Notes"; together with the Class A-1 Notes, the Class A-2 Notes and the Class A-3
Notes, the "Class A Notes"), Class B 4.30% Auto Loan Asset Backed Notes (the
"Class B Notes"), Class C 4.49% Auto Loan Asset Backed Notes (the "Class C
Notes"; and together with the Class A Notes and the Class B Notes, the "Notes")
pursuant to the Indenture dated as of July 7, 2005 (as amended and supplemented
from time to time, the "Indenture"), between the Issuer and U.S. Bank National
Association, as indenture trustee (the "Indenture Trustee");

         WHEREAS the Issuer desires to enter into a credit and liquidity
enhancement arrangement that will provide funding for certain required payments
of principal and interest on the Notes in the event that Available Funds and any
amounts on deposit in the Reserve Account that are available to be paid in
respect thereof to Noteholders on any Payment Date are insufficient to fund such
payments;

         WHEREAS BANA is willing to provide such credit and liquidity
enhancement on the terms described herein against delivery to it of the
Revolving Liquidity Note evidencing the obligation of the Issuer to repay
amounts so funded on the terms set forth herein and in the Revolving Liquidity
Note;

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein, and other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties agree as follows:

                                    ARTICLE I

                                   Definitions

         Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned such terms in Appendix A to the Sale Agreement dated
July 7, 2005 by and between BAS Securitization LLC, as Seller and the Issuer.

                                   ARTICLE II

                  Funding by Holder of REVOLVING LIQUIDITY NOTE

         Section 2.1 General Funding Obligation. Pursuant to Section 7.4 of the
Indenture, on each Determination Date, the Indenture Trustee shall calculate the
amount, if any, by which the

<PAGE>

amounts to be distributed in respect of interest on or principal of the Notes
and payments of higher priority pursuant to Sections 8.4 and 5.4(b) of the
Indenture exceed the amount of Available Funds that will be available to make
such payments (such event a "Shortfall Draw Event") and will determine whether
amounts on deposit in the Reserve Account, if any, that are available therefor
will be sufficient to fund such payments on the related Payment Date. If, in
accordance with the Indenture, the Indenture Trustee has determined that
Available Funds and amounts on deposit in the Reserve Account that will be
available to make such payments will be insufficient therefor, then the
Indenture Trustee on behalf of the Issuer will have the right to request the
holder of the Revolving Liquidity Note (the "Holder") to fund such shortfall
(such request, or any request for funding described in Section 2.2 hereof, a
"Draw"); provided that the Holder will not be obligated to fund any such
shortfall to the extent that the aggregate of the amounts funded by it hereunder
and not previously repaid equals or exceeds the Maximum Drawn Amount at such
time (the parties hereto agreeing that interest accrued on the Revolving
Liquidity Note as described herein will not be considered an amount funded by
the Holder for purposes of such calculation). "Maximum Drawn Amount" means, at
any time the greater of (a) the product of (i) 0.50% and (ii) the Pool Balance
as of the Cut-Off Date minus the YSOC Amount on the Closing Date and (b) the
product of (i) 1.25% and (ii) the Pool Balance as of the end of the related
Collection Period minus the YSOC Amount for the related Payment Date. The
"Undrawn Amount" of the Revolving Liquidity Note at any time is an amount equal
to the Maximum Drawn Amount less an amount equal to the aggregate of all amounts
funded pursuant to any previous Draw Requests (as defined in Section 2.3) that
have not yet been repaid pursuant to Section 2.4 (the parties hereto agreeing
that interest accrued on the Revolving Liquidity Note as described herein will
not be considered an amount funded by the Holder for purposes of such
calculation, and any amount paid in respect of such accrued interest will not be
considered to increase the Undrawn Amount). The "Drawn Amount" of the Revolving
Liquidity Note is an amount equal to the aggregate of all amounts funded
pursuant to any previous Draw Requests that have not yet been paid (it being
understood that interest accrued on the Revolving Liquidity Note will not be
considered an amount funded by the Holder for the purposes of such calculation.

         Section 2.2 Additional Funding Obligations. If at any time prior to the
Final Scheduled Payment Date either (i) the short-term unsecured debt rating of
the Holder falls below P-1 by Moody's or A-1+ by Standard & Poor's (or in either
case, such lower ratings as may be permitted by Moody's and S&P), (ii) the
long-term unsecured debt rating of the Holder falls below A1 by Moody's or AA-
by Standard & Poor's (or in either case, such lower ratings as may be permitted
by Moody's and S&P) or (iii) the Holder fails to fund the amount specified in
any Draw Request prepared and submitted to the Holder in accordance with
Sections 2.1 and 2.3 of this Agreement, then the Indenture Trustee on behalf of
the Issuer shall request that the entire Undrawn Amount of the Revolving
Liquidity Note be funded; provided, however, that the Indenture Trustee shall
not exercise its right to request that the entire Undrawn Amount of the
Revolving Liquidity Note be funded for five Business Days following the
occurrence of a downgrade event referred to in clause (i) or (ii) above, during
which time the Holder shall have the right to remedy such downgrade event by
assigning the Revolving Liquidity Note and this Agreement to a Permitted
Assignee pursuant to Section 2.5 or Section 3.3. Upon such assignment, the
downgrade event shall be deemed cured and therefore the Indenture Trustee shall
no longer be permitted to request that the entire Undrawn Amount of the
Revolving Liquidity Note be funded. To the extent the entire Undrawn Amount is
fully funded pursuant to this

                                       2
<PAGE>

Section 2.2, the Undrawn Amount shall be reduced to zero and shall no longer be
subject to draws.

         Section 2.3 Draw Mechanics. Not fewer than two Business Days prior to
the relevant Payment Date, in the case of a Draw described in Section 2.1, and
on any Business Day, in the case of a Draw described in Section 2.2, the Issuer,
by action of the Indenture Trustee (following the assignment of this Agreement
to the Indenture Trustee pursuant to Section 2.5 and until the Indenture
terminates in accordance with its provisions), may deliver a written request
(each such request, a "Draw Request") for funds in the amount of the shortfall
described in Section 2.1 or the entire Undrawn Amount in the case of a Draw
pursuant to Section 2.2. Any such Draw Request may be delivered by facsimile
transmission and hard copy to: Bank of America, National Association,
888-969-9285, Attn: Vilma Tang, Re: Banc of America Securities Auto Trust
2005-WF1 Revolving Liquidity Note Draw Request. Not later than 2:00 p.m. on the
Business Day following delivery of any Draw Request, the Holder will fund the
indicated draw by wire transfer of immediately available funds to (i) in the
case of a Draw described in Section 2.1, the Collection Account and (ii) in the
case of a Draw described in Section 2.2, (x) if a Shortfall Draw Event exists,
the Collection Account and (y) in all other circumstances, the Reserve Account.

         The Holder shall have no further obligation to fund draws on the
Revolving Liquidity Note pursuant to Sections 2.1 or 2.2 of this Agreement or
the Indenture after the Notes have been paid in full or redeemed pursuant to the
Indenture.

         Section 2.4 Repayment of Funded Draws. Subject to the following
sentences, the Issuer is obligated to repay all funded Draws together with
interest accrued on the daily outstanding balance of all funded Draws from the
date made until the date all funded Draws are repaid at the Effective Federal
Funds Rate. The "Effective Federal Funds Rate" shall mean, for any day, the sum
of (a) the weighted average (rounded upwards, if necessary, to the next 1/100 of
1%) of the rates on overnight Federal Funds transactions with members of the
Federal Reserve System arranged by Federal funds brokers, as published on the
next succeeding Business Day by the Federal Reserve Bank of New York, or, if
such rate is not so published for any day that is a Business Day, the average
(rounded upwards, if necessary, to the next 1/100 of 1%) of the quotations for
such day for such transactions received by the Indenture Trustee from three
Federal funds brokers of recognized standing selected by it plus (b) 0.50%. The
parties hereto (and the assignees and third-party beneficiaries hereof, by
accepting the assignment of this Agreement as contemplated in Section 2.5
hereof) agree that Draws will be repaid in part or in whole on any each
succeeding Payment Date on which amounts are available therefor in accordance
with the provisions of Section 8.4(x) or 5.4(b)(vi) of the Indenture, and
interest accrued on the daily outstanding amount of funded Draws will be payable
on and after the Payment Date on which all funded Draws are repaid and on which
amounts are available therefore in accordance with the provisions of Section
8.4(xi) or 5.4(b)(vii) of the Indenture. Payments to the Holder in respect of
funded Draws or accrued interest will be made by wire transfer of immediately
available funds to the following account, or such other account designated by
the Holder in writing:

         Ref: BASAT 05-WF1 RLN Draw Repayment
         Attn: Vilma Tang

         Notwithstanding the foregoing, if following liquidation of the Trust
Estate pursuant to Section 5.4(b) of the Indenture the Issuer has insufficient
funds to make required payments to the Holder of the Revolving Liquidity Note
pursuant to Sections 8.4 and 5.4(b) of the Indenture, then all amounts due under
the Revolving Liquidity Note will be deemed to have been paid in full and this
Agreement shall terminate with no further payment owing from the Issuer.

         Section 2.5 Assignment; Third Party Beneficiaries. The parties hereto
acknowledge and agree that:

                  (a) The right to receive amounts funded by the Holder under
         the Revolving Liquidity Note and all other rights of the Issuer under
         this Agreement will be assigned by the Issuer to the Indenture Trustee
         pursuant to the Indenture for the benefit of the Noteholders, and that
         the Indenture Trustee, on behalf of the Noteholders, and such
         Noteholders, are intended to be third-party beneficiaries of this
         Agreement from and after such assignment and until the Indenture is
         terminated in accordance with its terms. In addition, the Holder
         expressly acknowledges that, pursuant to the Indenture, the Indenture
         Trustee will exercise its right to request funds hereunder in every
         circumstance when such request may be made in accordance with the terms
         of this Agreement.

                  (b) The obligation to fund such draws as and when requested by
         the Issuer or Indenture Trustee by BANA, as holder of the Revolving
         Liquidity Note under this Agreement may be assigned at any time by BANA
         to a Permitted Assignee, and that such Permitted Assignee is intended
         to be a third-party beneficiary of this Agreement from and after such
         assignment and until all amounts due under the Revolving Liquidity Note
         have been paid in full and this Agreement and the Indenture is
         terminated in accordance with its terms. "Permitted Assignee" means, an
         Affiliate of BANA, so long as such Affiliate has at the time of
         assignment: (i) a short-term unsecured debt rating of P-1 by Moody's
         and A-1+ by Standard & Poor's (or in either case, such lower ratings as
         may be permitted by Moody's and S&P), and (ii) a long-term unsecured
         debt rating of A1 by Moody's and AA- by Standard & Poor's (or in either
         case, such lower ratings as may be permitted by Moody's and S&P).

                  (c) Nothing in this Agreement or in the Revolving Liquidity
         Note, whether express or implied, shall be construed to give to any
         other Person any legal or equitable right, remedy or claim under or in
         respect of this Agreement or the Revolving Liquidity Note, or any
         covenants, conditions or provisions contained herein or therein.

                                  ARTICLE III

                            REVOLVING LIQUIDITY NOTE

         Section 3.1 Issuance of Revolving Liquidity Note. On the date hereof,
the Issuer will execute and deliver to the Holder, and the Owner Trustee will
authenticate, a physical certificate evidencing the Revolving Liquidity Note,
substantially in the form of Exhibit A hereto. Each Revolving Liquidity Note
issued hereunder will evidence the repayment obligations of the Issuer set forth
in Section 2.4 hereof and the funding obligations of the Holder thereof set
forth in Section 2.1 and 2.2 hereof, and will be dated the date of its issuance.

         Section 3.2 Terms. Upon issuance, the initial Undrawn Amount of the
Revolving Liquidity Note shall be $11,124,500. The Undrawn Amount will be
reduced by the amount of each Draw funded by the Holder, and increased by
amounts repaid to the Holder pursuant to Section 2.4 up to a maximum of the
Maximum Drawn Amount, excluding interest paid on the Revolving Liquidity Note.
Interest will accrue on the average daily outstanding Drawn Amount from and
including the date of any Draw to but excluding the date on which the Drawn
Amount is reduced to zero. Although the Revolving Liquidity Note is secured by
the Trust Estate, all payments in respect of funded Draws and interest accrued
thereon shall be fully subordinated to required payments to the Noteholders and
to required deposits into the Reserve Account as set forth in the Indenture.

         Section 3.3 Transfer. Prior to the termination of the Indenture, the
Holder may not transfer, assign or convey the Revolving Liquidity Note or this
Agreement unless: (i) the purported transferee, assignee or recipient of such
conveyance has executed a written agreement to be bound by all of the terms and
provisions of this Agreement; (ii) such action shall not, as evidenced by an
Opinion of Counsel delivered to the Owner Trustee and the Indenture Trustee,
adversely affect in any material respect the interests of any Noteholder or
Certificateholder; (iii) the Rating Agency Condition has been satisfied, and
(iv) the purported transferee, assignee or recipient of such conveyance is a
"domestic corporation" within the meaning of Section 7701(a)(30)(C) of the Code
that has not made the election under Section 1362(a)(1) of the Code to be
treated as an S corporation; provided, however, that an assignment to a
Permitted Assignee need not comply with the conditions set forth in clauses (ii)
and (iii) above. The Revolving Liquidity Note may not be transferred, assigned
or conveyed in part; any transfer, conveyance or assignment must be in respect
of 100% of the Revolving Liquidity Note. The Issuer will maintain a register in
which it will record the name and contact information for each Holder. No
transfer, assignment or conveyance of the Revolving Liquidity Note will be
effective prior to notice to the Issuer and the Indenture Trustee and
recordation by the Issuer thereof in such register.

         No transfer will be effective unless the Indenture Trustee has received
a certification from the transferee to the effect that such transferee is not an
"employee benefit plan" as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), whether or not such employee
benefit plan is subject to the provisions of Title I of ERISA (including,
without limitation, government and foreign plans), (b) a "plan" described in
Section 4975(e)(1) of the Code or (c) any entity whose underlying assets include
"plan assets" by reason of any such employee benefit plan's or other plan's
investment in such entity (including, without limitation, group trusts, bank
collective investment trusts, insurance company separate accounts and certain
insurance company general accounts) (each, a "Benefit Plan Investor").

                                       5
<PAGE>

         Section 3.4 No Set-Off. Without affecting the provisions of this
Agreement requiring the calculation of payment amounts, all payments under this
Agreement will be made without set-off or counterclaim, and the parties hereto
waive any right of set-off or counterclaim that any such party may have at law
or equity.

                                   ARTICLE IV

                            Miscellaneous Provisions

         Section 4.1 Fees and Expenses. On the Closing Date, BANA shall receive
a commitment fee in the amount of $557,000 as consideration for serving as the
initial holder of the Revolving Liquidity Note.

         Section 4.2 Assignment by Issuer. The Holder hereby acknowledges and
consents to any mortgage, pledge, assignment and grant of a security interest by
the Issuer to the Indenture Trustee pursuant to the Indenture for the benefit of
the Noteholders of all right, title and interest of the Issuer to and/or the
assignment of any or all of the Issuer's rights and obligations hereunder to the
Indenture Trustee.

         Section 4.3 Amendments to Agreement. (a) Any term or provision of this
Agreement may be amended by the Issuer and the Holder with prior notice to each
Rating Agency but without the consent of the Indenture Trustee, any Noteholder,
or the Owner Trustee; provided that such amendment shall not, as evidenced by an
Officer's Certificate of the Depositor delivered to the Indenture Trustee and
the Owner Trustee materially and adversely affect the interests of the
Noteholders, the Indenture Trustee or the Owner Trustee; provided, further, that
any amendment entered into pursuant to this Section 4.3(a) shall not
significantly change the permitted activities of the Issuer and the Holder.

                  (b) Any term or provision of this Agreement may be amended by
         the Issuer and the Holder with prior notice to each Rating Agency but
         without the consent of the Indenture Trustee, any Noteholder, the Owner
         Trustee or any other Person to add, modify or eliminate any provisions
         as may be necessary or advisable in order to enable the Issuer, the
         Holder or any of their Affiliates to comply with or obtain more
         favorable treatment under any law or regulation or any accounting rule
         or principle, provided that such amendment does not, as evidenced by an
         Officer's Certificate of the Depositor delivered to the Indenture
         Trustee and the Owner Trustee, materially and adversely affect the
         interests of Noteholders; provided, further that the Rating Agency
         Condition with respect to Standard & Poor's shall have been satisfied;
         provided, further that any amendment entered into pursuant to this
         Section 4.3(b) shall not significantly change the permitted activities
         of the Issuer and the Holder.

                  (c) This Agreement may also be amended from time to time by
         the Issuer and the Holder with prior notice to each Rating Agency and
         with the consent of the Holders of a majority of the Note Balance of
         the Controlling Class for the purpose of adding any provisions to or
         changing in any manner or eliminating any of the provisions of this
         Agreement or of modifying in any manner the rights of the Noteholders.
         It will not be necessary for the consent of the Noteholders to approve
         the particular form of any

                                       6
<PAGE>

         proposed amendment or consent, but it will be sufficient if such
         consent approves the substance thereof. The manner of obtaining such
         consents (and any other consents of Noteholders provided for in this
         Agreement) and of evidencing the authorization of the execution thereof
         by Noteholders will be subject to such reasonable requirements as the
         Indenture Trustee may prescribe, including the establishment of record
         dates pursuant to the Note Depository Agreement.

                  (d) Prior to the execution of any amendment to this Agreement,
         the Issuer or the Holder shall provide written notification of the
         substance of such amendment to each Rating Agency; and promptly after
         the execution of any such amendment or consent, the Issuer or the
         Holder shall furnish a copy of such amendment or consent to each Rating
         Agency and the Indenture Trustee.

                  (e) Prior to the execution of any amendment to this Agreement,
         the Holder shall be entitled to receive and conclusively rely upon an
         Opinion of Counsel stating that the execution of such amendment is
         authorized or permitted by this Agreement and that all conditions
         precedent to the execution and delivery of such amendment have been
         satisfied. The Holder may, but shall not be obligated to, enter into
         any such amendment which adversely affects the Holder's own rights,
         duties or immunities under this Agreement. Furthermore, notwithstanding

                 BANC OF AMERICA SECURITIES AUTO TRUST 2005-WF1
                            REVOLVING LIQUIDITY NOTE

                        Representing a Maximum Amount of
                         Funded Draws outstanding at any
                         time not to exceed $11,124,500

         This certifies that BANK OF AMERICA, NATIONAL ASSOCIATION (the
"Holder") is the registered owner of this Revolving Liquidity Note representing
the right to receive the payment of certain Draws funded as described in the
Revolving Liquidity Note Agreement (the "Revolving Liquidity Note Agreement")
dated as of July 7, 2005, between Banc of America Securities Auto Trust
2005-WF1, as issuer (the "Issuer") and Bank of America, National Association, as
initial holder hereof. Capitalized terms used herein and not defined herein
shall have the meanings ascribed thereto in the Revolving Liquidity Note
Agreement and in Appendix A to the Sale Agreement dated as of July 7, 2005,
between the Issuer and BAS Securitization LLC, as seller (the "Sale Agreement").

         This Revolving Liquidity Note represents a 100% undivided interest in
the right of the Holder to receive repayment in full of the aggregate amount of
funded Draws and interest accrued thereon as and to the extent such amounts are
payable in accordance with the Revolving Liquidity Note Agreement. All of the
provisions of the Revolving Liquidity Note Agreement and the Indenture are
incorporated by reference and comprise integral parts of this Revolving
Liquidity Note. The following summary of certain provisions thereof is not and
does not purport

                                  Exhibit A-2
<PAGE>

to be complete. By its acceptance hereof, the holder of this Revolving Liquidity
Note (the "Holder") assents to and is bound by the terms, provisions and
conditions of the Revolving Liquidity Note Agreement, including the provisions
thereof (i) setting forth the obligation of the Holder of this Revolving
Liquidity Note to fund Draws as and when properly requested pursuant to Article
II thereof, (ii) specifying that this Revolving Liquidity Note is secured only
by certain assets of the Issuer and is payable only from certain collections in
respect thereof that are available for such purpose in accordance with the
priority of payments set forth in Sections 8.4 and 5.4(b) of the Indenture, and
(iii) specifying that all payments in respect of funded Draws and interest
accrued thereon shall be fully subordinated to required payments to the holders
of certain other securities issued by the Issuer and to required deposits into a
specified Reserve Account established for the benefit of the holders of such
other securities in accordance with the Indenture.

         "Maximum Drawn Amount" means, at any time, the greater of (a) the
product of (i) 0.50% and (ii) the Pool Balance as of the Cut-Off Date minus the
YSOC Amount on the Closing Date and (b) the product of (i) 1.25% and (ii) the
Pool Balance as of the end of the related Collection Period minus the YSOC
Amount for the related Payment Date. The "Undrawn Amount" of the Revolving
Liquidity Note at any time is an amount equal to the Maximum Drawn Amount at
such time less an amount equal to the aggregate of all amounts funded pursuant
to any previous Draw Requests that have not yet been repaid pursuant to Section
2.4 of the Revolving Liquidity Note Agreement, and increased by amounts repaid
to the Holder pursuant to Section 2.4 of the Revolving Liquidity Note Agreement
(interest accrued on the Revolving Liquidity Note not being considered an amount
funded by the Holder for purposes of such calculation, and any amount paid in
respect of such accrued interest will not be considered to increase the Undrawn
Amount). To the extent the entire Undrawn Amount is fully funded pursuant to
Section 2.2 of the Revolving Liquidity Note Agreement, the Undrawn Amount shall
be reduced to zero and shall no longer be subject to draws. The "Drawn Amount"
of the Revolving Liquidity Note is an amount equal to the aggregate of all
amounts funded pursuant to any previous Draw Requests that have not yet been
paid (it being understood that interest accrued on the Revolving Liquidity Note
will not be considered an amount funded by the Holder for the purposes of such
calculation. Interest will accrue on the average daily outstanding Drawn Amount
from and including the date of any Draw to but excluding the date on which the
Drawn Amount is reduced to zero at the Effective Federal Funds Rate.

         Subject to the more detailed provisions concerning payments to be made
to the Holder of the Revolving Liquidity Note set forth in the Revolving
Liquidity Note Agreement and the Indenture, generally, repayment of Draws
previously funded by the (or a) Holder of the Revolving Liquidity Note, and
interest accrued thereon as described below, will be made on the 18th day of
each calendar month, or if such day is not a Business Day, then on the next
succeeding Business Day, to the extent funds are available therefor.
Notwithstanding the foregoing, if following liquidation of the Trust Estate
pursuant to Section 5.4(b) of the Indenture the Issuer has insufficient funds to
make required payments to the Holder of the Revolving Liquidity Note pursuant to
Sections 8.4 and 5.4(b) of the Indenture, then all amounts due under the
Revolving Liquidity Note will be deemed to have been paid in full and this
Agreement shall terminate with no further payment owing from the Issuer.

                                  Exhibit A-3
<PAGE>

         Any term or provision of this Agreement may be amended pursuant to
Section 4.3 of the Revolving Liquidity Note Agreement by the Issuer and the
Holder with prior notice to each Rating Agency but without the consent of the
Indenture Trustee, any Noteholder, or the Owner Trustee; provided that such
amendment shall not, as evidenced by an Officer's Certificate of the Seller
delivered to the Indenture Trustee and the Owner Trustee materially and
adversely affect the interests of the Noteholders, the Indenture Trustee or the
Owner Trustee or to add, modify or eliminate any provisions as may be necessary
or advisable in order to enable the Issuer, the Holder or any of their
Affiliates to comply with or obtain more favorable treatment under any law or
regulation or any accounting rule or principle, it being a condition to any such
amendment that any such amendment shall not significantly change the permitted
activities of the Issuer or the Holder and the Rating Agency Condition shall
have been satisfied only with respect to Standard & Poor's. This Agreement may
also be amended from time to time by the Issuer and the Holder with prior notice
to each Rating Agency and with the consent of the Holders of a majority of the
Note Balance of the Controlling Class, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Agreement or of modifying in any manner the rights of the Noteholders. It will
not be necessary for the consent of the Noteholders to approve the particular
form of any proposed amendment or consent, but it will be sufficient if such
consent approves the substance thereof. The manner of obtaining such consents
(and any other consents of Noteholders provided for in this Agreement) and of
evidencing the authorization of the execution thereof by Noteholders will be
subject to such reasonable requirements as the Indenture Trustee may prescribe,
including the establishment of record dates pursuant to the Note Depository
Agreement.

         Prior to the termination of the Indenture, the Holder may not transfer,
assign or convey this Revolving Liquidity Note or the Revolving Liquidity Note
Agreement unless: (i) the purported transferee, assignee or recipient of such
conveyance has executed a written agreement to be bound by all of the terms and
provisions of the Revolving Liquidity Note Agreement; (ii) such action shall
not, as evidenced by an Opinion of Counsel delivered to the Owner Trustee and
the Indenture Trustee, adversely affect in any material respect the interests of
any Noteholder or Certificateholder; and (iii) the Rating Agency Condition has
been satisfied; provided, however, that an assignment to a Permitted Assignee
need not comply with the conditions set forth in clauses (ii) and (iii) above.
The Revolving Liquidity Note may not be transferred, assigned or conveyed in
part; any transfer, conveyance or assignment must be in respect of 100% of this
Revolving Liquidity Note. The Issuer will maintain a register in which it will
record the name and contact information for each Holder. No transfer, assignment
or conveyance of this Revolving Liquidity Note will be effective prior to notice
to the Issuer and the Indenture Trustee and recordation by the Issuer thereof in
such register.

         No recourse may be taken, directly or indirectly, with respect to the
obligations of the Holder of this Revolving Liquidity Note under the Revolving
Liquidity Note Agreement or other writing delivered in connection herewith or
therewith, against (i) the Indenture Trustee or the Owner Trustee in its
individual capacity, (ii) any Certificateholder or other owner of a beneficial
interest in the Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director, employee or agent of the Indenture Trustee or the Owner Trustee in its
individual capacity, any Certificateholder or other owner of a beneficial
interest in the Issuer, the Owner Trustee or the Indenture Trustee or of any
successor or assign of the Indenture Trustee or the Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being

                                  Exhibit A-4
<PAGE>

understood that the Indenture Trustee and the Owner Trustee, in their capacities
as such, have no such obligations in their individual capacity) and except that
any such partner, owner or beneficiary shall be fully liable, to the extent
provided by applicable law, for any unpaid consideration for stock, unpaid
capital contribution or failure to pay any installment or call owing to such
entity.

         By its acceptance of this Revolving Liquidity Note, the Holder agrees
that it will not, prior to the date which is one year and one day after the
termination of the Revolving Liquidity Note Agreement with respect to the Issuer
or Seller, acquiesce, petition or otherwise invoke or cause the Issuer to invoke
the process of any court or government authority for the purpose of commencing
or sustaining a case against the Issuer or Seller under any federal or state
bankruptcy, insolvency or similar law, or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Issuer or Seller or any substantial part of the property of either of them, or
ordering the winding up or liquidation of the affairs of the Issuer or Seller.

         THIS REVOLVING LIQUIDITY NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

                                  Exhibit A-5

<PAGE>

                                   ARTICLE II

                                    PURCHASE

     SECTION 2.1 Agreement to Sell and Contribute on the Closing Date. On the
terms and subject to the conditions set forth in this Agreement, BANA does
hereby irrevocably sell, transfer, assign and otherwise convey to the Purchaser
without recourse (subject to the obligations herein) on the Closing Date all of
its right, title and interest in, to and under the following property and
identified in an Assignment substantially in the form of Exhibit A delivered on
the Closing Date (collectively, the "Purchased Assets"):

               (i) the Receivables listed on the Schedule of Receivables and all
          monies received thereon, on and after the Cut-Off Date;

               (ii) the Related Security;

               (iii) the Receivable Files;

               (iv) all of BANA's rights in the Originator Purchase Agreement
          and the Servicing Agreement; and

               (v) any proceeds of the property described above.

The sale, transfer, assignment and conveyance made hereunder does not constitute
and is not intended to result in an assumption by the Purchaser of any
obligation of BANA or any Originator to the Obligors or any other Person in
connection with the Receivables or the other assets and properties conveyed
hereunder or any agreement, document or instrument related thereto.

     SECTION 2.2 Consideration and Payment. In consideration of the sale of the
Purchased Assets sold to the Purchaser on the Closing Date, the Purchaser shall
pay to BANA on such date an amount equal to the estimated fair market value of
the Purchased Assets on the Closing Date.

                                  ARTICLE III

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

     SECTION 3.1 Representations and Warranties of BANA. BANA makes the
following representations and warranties as of the Closing Date on which the
Purchaser will be deemed to have relied in acquiring the Purchased Assets. The
representations and warranties will survive the conveyance of the Purchased
Assets to the Purchaser, the conveyance of the Purchased Assets to the Issuer
pursuant to the Sale Agreement and the pledge thereof by the Issuer to the
Indenture Trustee pursuant to the Indenture:

     (a) Existence and Power. BANA is a national banking association validly
existing and in good standing under the laws of the United States and has, in
all material respects, full power and authority to own its assets and operate
its business as presently owned or operated, and to execute, deliver and perform
its obligations under the Transaction Documents to which it

                                      -2-
                                                   Purchase Agreement (2005-WF1)
<PAGE>

is a party or affect the enforceability or collectibility of the Receivables or
any other part of the Purchased Assets. BANA has obtained all necessary licenses
and approvals in each jurisdiction where the failure to do so would materially
and adversely affect the ability of BANA to perform its obligations under the
Transaction Documents or affect the enforceability or collectibility of the
Receivables or any other part of the Purchased Assets.

     (b) Authorization and No Contravention. The execution, delivery and
performance by BANA of the Transaction Documents to which it is a party have
been duly authorized by all necessary action on the part of BANA and do not
contravene or constitute a default under (i) any applicable law, rule or
regulation, (ii) its organizational documents or (iii) any material indenture or
material agreement or instrument to which BANA is a party or by which its
properties are bound (other than violations of such laws, rules, regulations,
indentures or agreements which do not affect the legality, validity or
enforceability of any of such agreements and which, individually or in the
aggregate, would not materially and adversely affect the transactions
contemplated by, or BANA's ability to perform its obligations under, the
Transaction Documents).

     (c) No Consent Required. No approval or authorization by, or filing with,
any Governmental Authority is required in connection with the execution,
delivery and performance by BANA of any Transaction Document other than (i) UCC
filings, (ii) approvals and authorizations that have previously been obtained
and filings that have previously been made and (iii) approvals, authorizations
or filings which, if not obtained or made, would not have a material adverse
effect on the enforceability or collectibility of the Receivables or any other
part of the Purchased Assets or would not materially and adversely affect the
ability of BANA to perform its obligations under the Transaction Documents.

     (d) Binding Effect. Each Transaction Document to which BANA is a party
constitutes the legal, valid and binding obligation of BANA enforceable against
BANA in accordance with its terms, except as such enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, moratorium, receivership,
conservatorship or other similar laws affecting the enforcement of creditors'
rights generally and, if applicable, the rights of creditors of limited
liability companies from time to time in effect or by general principles of
equity.

     (e) No Proceedings. There are no actions, orders, suits or proceedings
pending or, to the knowledge of BANA, threatened against BANA before or by any
Governmental Authority that (i) assert the invalidity or unenforceability of
this Agreement or any of the other Transaction Documents, (ii) seek to prevent
the issuance of the Notes or the consummation of any of the transactions
contemplated by this Agreement or any of the other Transaction Documents, (iii)
seek any determination or ruling that would materially and adversely affect the
performance by BANA of its obligations under this Agreement or any of the other
Transaction Documents or have a material adverse effect on the Noteholders or
(iv) relating to BANA that would materially and adversely affect the federal or
Applicable Tax State income, excise, franchise or similar tax attributes of the
Notes.

     (f) Lien Filings. BANA is not aware of any material judgment, ERISA or tax
lien filings against BANA.

<PAGE>

     SECTION 3.2 Representations and Warranties of BANA as to each Receivable.
On the date hereof, with respect to the Transferred Receivables BANA hereby
makes the representations and warranties set forth on Schedule I to the Sale
Agreement to the Purchaser as to the Receivables sold, transferred, assigned and
otherwise conveyed to the Purchaser under this Agreement on which such
representations and warranties the Purchaser relies in acquiring the
Receivables. Such representations and warranties shall survive the sale of the
Receivables to the Issuer under the Sale Agreement, and the Grant of the
Receivables by the Issuer to the Indenture Trustee pursuant to the Indenture.
Notwithstanding any statement to the contrary contained herein or in any other
Transaction Document, BANA shall not be required to notify any insurer with
respect to any Insurance Policy obtained by an Obligor.

     SECTION 3.3 Repurchase upon Breach. Upon discovery by or notice to the
Purchaser or BANA of a breach of any of the representations and warranties
described in Section 3.2 which materially and adversely affects the interests of
the Issuer or the Noteholders, the party discovering such breach or receiving
such notice shall give prompt written notice thereof to the other party hereto
and to the Originator; provided, that the failure to give such notice shall not
affect any obligation of BANA hereunder. If the breach materially and adversely
affects the interests of the Issuer or the Noteholders in such Receivable, then
BANA shall either (a) correct or cure such breach or (b) purchase such
Receivable from the holder thereof, in either case on or before the Payment Date
following the end of the Collection Period which includes the 60th day after the
date BANA and the Originator became aware or was notified of such breach. Any
such purchase by BANA shall be at a price equal to the Repurchase Price. In
consideration for such repurchase, BANA shall make (or shall cause to be made) a
payment to the Purchaser equal to the Repurchase Price by depositing (or causing
to be deposited) such amount into the Collection Account prior to 4:00 p.m., New
York City time on the Business Day immediately preceding such Payment Date. Upon
payment of such Repurchase Price by BANA, the Purchaser shall release and shall
execute and deliver such instruments of release, transfer or assignment, in each
case without recourse or representation, as may be reasonably requested by BANA
to evidence such release, transfer or assignment or more effectively vest in
BANA or its designee any Receivable and related Purchased Assets repurchased
pursuant to this Section 3.3. It is understood and agreed that the obligation of
BANA to purchase any Receivable as described above shall constitute the sole
remedy respecting such breach available to the Purchaser.

     SECTION 3.4 Protection of Title.

     (a) BANA shall authorize and file such financing statements and cause to be
authorized and filed such continuation and other statements, all in such manner
and in such places as may be required by law fully to preserve, maintain and
protect the interest of the Purchaser under this Agreement in the Receivables
(other than any Related Security with respect thereto, to the extent that the
interest of the Purchaser therein cannot be perfected by the filing of a
financing statement). BANA shall deliver (or cause to be delivered) to the
Purchaser file-stamped copies of, or filing receipts for, any document filed as
provided above, as soon as available following such filing.

     (b) BANA shall not change its name, identity, corporate structure or
jurisdiction of organization in any manner that would make any financing
statement or continuation statement filed by BANA in accordance with paragraph
(a) above "seriously misleading" within the

                                      -4-
                                                   Purchase Agreement (2005-WF1)
<PAGE>

meaning of Sections 9-506, 9-507 or 9-508 of the UCC, unless it shall have given
the Purchaser at least five days' prior written notice thereof and, to the
extent necessary, shall have promptly filed amendments to previously filed
financing statements or continuation statements described in paragraph (a) above
or filed new financing statements, as applicable.

     (c) BANA shall give the Purchaser at least five days' prior written notice
of any change of location of BANA for purposes of Section 9-307 of the UCC and
shall have taken all action prior to making such change (or shall have made
arrangements to take such action substantially simultaneously with such change,
if it is not possible to take such action in advance) reasonably necessary or
advisable in the opinion of the Purchaser to amend all previously filed
financing statements or continuation statements described in paragraph (a) above
or to file new financing statements, as applicable.

     (d) BANA shall maintain its computer systems so that, from time to time
after the conveyance under this Agreement of the Receivables, any master
computer records (including any backup archives) that refer to a Receivable
shall indicate clearly the interest of the Purchaser (or any subsequent assignee
of the Purchaser) in such Receivable and that such Receivable is owned by such
Person.

     (e) If at any time BANA shall propose to sell, grant a security interest in
or otherwise transfer any interest in motor vehicle receivables to any
prospective purchaser, lender or other transferee, BANA shall give to such
prospective purchaser, lender or other transferee computer tapes, records or
printouts (including any restored from backup archives) that, if they shall
refer in any manner whatsoever to any Receivable, shall indicate clearly that
such Receivable has been sold and is owned by the Purchaser (or any subsequent
assignee of the Purchaser).

     SECTION 3.5 Other Liens or Interests. Except for the conveyances and grants
of security interests pursuant to this Agreement and the other Transaction
Documents, BANA shall not sell, pledge, assign or transfer the Receivables or
other property transferred to the Purchaser to any other Person, or grant,
create, incur, assume or suffer to exist any Lien (other than Permitted Liens)
on any interest therein, and BANA shall defend the right, title and interest of
the Purchaser in, to and under such Receivables or other property transferred to
the Purchaser against all claims of third parties claiming through or under
BANA.

     SECTION 3.6 Perfection Representations, Warranties and Covenants. BANA
hereby makes the perfection representations, warranties and covenants attached
hereto as Schedule I to the Purchaser and the Purchaser shall be deemed to have
relied on such representations, warranties and covenants in acquiring the
Purchased Assets.

                                   ARTICLE IV

                                  MISCELLANEOUS

     SECTION 4.1 Transfers Intended as Sale; Security Interest.

     (a) Each of the parties hereto expressly intends and agrees that the
transfers contemplated and effected under this Agreement are complete and
absolute sales and transfers rather than pledges or assignments of only a
security interest and shall be given effect as such for

                                      -5-
                                                   Purchase Agreement (2005-WF1)
<PAGE>

all purposes. It is further the intention of the parties hereto that the
Receivables and related Purchased Assets shall not be treated as property of
BANA by the FDIC or other governmental authority acting as conservator or
receiver of BANA in a conservatorship, receivership, insolvency or other similar
proceeding in respect of BANA under the Federal Deposit Insurance Act, 12 U.S.C.
Section 1811 et seq or other applicable law. The sales and transfers by BANA of
the Receivables and related Purchased Assets hereunder are and shall be without
recourse to, or representation or warranty (express or implied) by, BANA, except
as otherwise specifically provided herein. The limited rights of recourse
specified herein against BANA are intended to provide a remedy for breach of
representations and warranties relating to the condition of the property sold,
rather than to the collectibility of the Receivables.

     (b) Notwithstanding the foregoing, in the event that the Receivables and
other Purchased Assets are held to be property of BANA, or if for any reason
this Agreement is held or deemed to create indebtedness or a security interest
in the Receivables and other Purchased Assets, then it is intended that:

          (i) This Agreement shall be deemed to be a security agreement within
     the meaning of Articles 8 and 9 of the New York Uniform Commercial Code and
     the Uniform Commercial Code of any other applicable jurisdiction;

          (ii) The conveyance provided for in Section 2.1 shall be deemed to be
     a grant by BANA of, and BANA hereby grants to the Purchaser, a security
     interest in all of its right (including the power to convey title thereto),
     title and interest, whether now owned or hereafter acquired, in and to the
     Receivables and other Purchased Assets, to secure such indebtedness and the
     performance of the obligations of BANA hereunder;

          (iii) The possession by the Purchaser or its agent of the Receivables
     Files and any other property as constitute instruments, money, negotiable
     documents or chattel paper shall be deemed to be "possession by the secured
     party" or possession by the purchaser or a person designated by such
     purchaser, for purposes of perfecting the security interest pursuant to the
     New York Uniform Commercial Code and the Uniform Commercial Code of any
     other applicable jurisdiction; and

          (iv) Notifications to persons holding such property, and
     acknowledgments, receipts or confirmations from persons holding such
     property, shall be deemed to be notifications to, or acknowledgments,
     receipts or confirmations from, bailees or agents (as applicable) of the
     Purchaser for the purpose of perfecting such security interest under
     applicable law.

     SECTION 4.2 Notices, Etc. All demands, notices and communications hereunder
shall be in writing and shall be delivered or mailed by registered or certified
first-class United States mail, postage prepaid, hand delivery, prepaid courier
service, or by facsimile, and addressed in each case as specified on Schedule II
to the Sale Agreement or at such other address as shall be designated in a
written notice to the other parties hereto. Any notice required or permitted to
be mailed to a Noteholder shall be given by first class mail, postage prepaid,
at the address of such Noteholder as shown in the Note Register. Delivery shall
occur only upon receipt or reported tender of such communication by an officer
of the recipient entitled to receive such notices

                                      -6-

<PAGE>

located at the address of such recipient for notices hereunder; provided,
however, that any notice to a Noteholder mailed within the time prescribed in
this Agreement shall be conclusively presumed to have been duly given, whether
or not the Noteholder shall receive such notice.

     SECTION 4.3 Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH LAWS OF THE STATE OF NEW YORK, INCLUDING SECTION
5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW BUT EXCLUDING TO THE
MAXIMUM EXTENT PERMITTED BY LAW ALL OTHER CONFLICT OF LAW PROVISIONS, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

     SECTION 4.4 Headings. The section headings hereof have been inserted for
convenience only and shall not be construed to affect the meaning, construction
or effect of this Agreement.

     SECTION 4.5 Counterparts. This Agreement may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but
all of such counterparts shall together constitute but one and the same
instrument.

     SECTION 4.6 Amendment.

     (a) Any term or provision of this Agreement may be amended by BANA and the
Purchaser with prior notice to each Rating Agency but without the consent of the
Indenture Trustee, any Noteholder, the Issuer or the Owner Trustee; provided
that such amendment shall not, as evidenced by an Officer's Certificate of the
Depositor delivered to the Indenture Trustee materially and adversely affect the
interests of any Noteholder; provided, further, that any amendment entered into
pursuant to this Section 4.6(a) shall not significantly change the permitted
activities of the Issuer.

     (b) Any term or provision of this Agreement may be amended by BANA and the
Purchaser with prior notice to each Rating Agency but without the consent of the
Indenture Trustee, any Noteholder, the Issuer, the Owner Trustee or any other
Person to add, modify or eliminate any provisions as may be necessary or
advisable in order to enable the Seller, the Depositor or any of their
Affiliates to comply with or obtain more favorable treatment under any law or
regulation or any accounting rule or principle; provided that such amendment
shall not, as evidenced by an Officer's Certificate of the Depositor delivered
to the Indenture Trustee materially and adversely affect the interests of any
Noteholder; provided, further, that the Rating Agency Condition with respect to
Standard & Poor's shall have been satisfied; provided, further, that any
amendment entered into pursuant to this Section 4.6(b) shall not significantly
change the permitted activities of the Issuer.

     (c) This Agreement may also be amended from time to time by BANA and the
Purchaser, with prior notice to each Rating Agency and with the consent of the
Holders of Notes evidencing not less than a majority of the Note Balance of the
Controlling Class, for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Noteholders. It will not be

                                      -7-

<PAGE>

necessary for the consent of Noteholders to approve the particular form of any
proposed amendment or consent, but it will be sufficient if such consent
approves the substance thereof. The manner of obtaining such consents (and any
other consents of Noteholders provided for in this Agreement) and of evidencing
the authorization of the execution thereof by Noteholders will be subject to
such reasonable requirements as the Indenture Trustee may prescribe, including
the establishment of record dates pursuant to the Note Depository Agreement.

     (d) Prior to the execution of any such amendment, BANA shall provide
written notification of the substance of such amendment to each Rating Agency;
and promptly after the execution of any such amendment or consent, BANA shall
furnish a copy of such amendment or consent to each Rating Agency and the
Indenture Trustee.

     (e) Prior to the execution of any amendment to this Agreement, the
Purchaser, the Owner Trustee and the Indenture Trustee shall be entitled to
receive and conclusively rely upon an Opinion of Counsel stating that the

                                   SCHEDULE I

              PERFECTION REPRESENTATIONS, WARRANTIES AND COVENANTS

         In addition to the representations, warranties and covenants contained
in the Purchase Agreement, BANA hereby represents, warrants, and covenants to
the Purchaser as follows on the Closing Date:

                                     GENERAL

     1. This Agreement creates a valid and continuing security interest (as
defined in the applicable UCC) in the Receivables and the other Purchased Assets
in favor of the Purchaser, which security interest is prior to all other Liens,
and is enforceable as such as against creditors of and purchasers from BANA.

     2. The Receivables constitute "chattel paper" (including "electronic
chattel paper" or "tangible chattel paper"), "accounts," "instruments" or
"general intangibles," within the meaning of the UCC.

     3. Each Receivable is secured by a first priority validly perfected
security interest in the related Financed Vehicle in favor of the Originator or
BANA, as secured party, or all necessary actions with respect to such Receivable
have been taken or will be taken to perfect a first priority security interest
in the related Financed Vehicle in favor of the Originator or BANA, as secured
party.

                                    CREATION

     4. Immediately prior to the sale, transfer, assignment and conveyance of a
Receivable by BANA to the Purchaser, BANA owned and had good and marketable
title to such Receivable free and clear of any Lien and immediately after the
sale, transfer, assignment and conveyance of such Receivable to the Purchaser,
the Purchaser will have good and marketable title to such Receivable free and
clear of any Lien.

     5. The related Originator has received all consents and approvals to the
sale of the Receivables hereunder to the Purchaser required by the terms of the
Receivables that constitute instruments.

                                   PERFECTION

     6. BANA has caused or will have caused, within ten days after the effective
date of this Agreement, the filing of all appropriate financing statements in
the proper filing office in the appropriate jurisdictions under applicable law
in order to perfect the sale of the Receivables from BANA to the Purchaser, and
the security interest in the Receivables granted to the Purchaser hereunder; and
the Servicer, in its capacity as custodian, has in its possession the original
copies of such instruments or tangible chattel paper that constitute or evidence
the Receivables, and all financing statements referred to in this paragraph
contain a statement that: "A purchase of or security interest in any collateral
described in this financing statement will violate the rights of the Secured
Party".

                                       -1-
                                                   Purchase Agreement (2005-WF1)
<PAGE>

     7. With respect to Receivables that constitute an instrument or tangible
chattel paper, either:

        (i)    All original executed copies of each such instrument or tangible
               chattel paper have been delivered to the Indenture Trustee; or

        (ii)   Such instruments or tangible chattel paper are in the possession
               of the Servicer and the Indenture Trustee has received a written
               acknowledgment from the Servicer that the Servicer (in its
               capacity as custodian) is holding such instruments or tangible
               chattel paper solely on behalf and for the benefit of the
               Indenture Trustee; or

        (iii)  The Servicer received possession of such instruments or tangible
               chattel paper after the Indenture Trustee received a written
               acknowledgment from the Servicer that the Servicer is acting
               solely as agent of the Indenture Trustee.

                                    PRIORITY

     8. BANA has not authorized the filing of, and is not aware of, any
financing statements against BANA that include a description of collateral
covering the Receivables other than any financing statement (i) relating to the
security interest granted to the Purchaser hereunder or (ii) that has been
terminated.

     9. BANA is not aware of any material judgment, ERISA or tax lien filings
against BANA.

     10. Neither BANA nor a custodian holding any Receivable that is electronic
chattel paper has communicated an authoritative copy of any loan agreement that
constitutes or evidences such Receivable to any Person other than the Servicer.

     11. None of the instruments, tangible chattel paper or electronic chattel
paper that constitute or evidence the Receivables has any marks or notations
indicating that they have been pledged, assigned or otherwise conveyed to any
Person other than the Purchaser, the Issuer or the Indenture Trustee.

                     SURVIVAL OF PERFECTION REPRESENTATIONS

     12. Notwithstanding any other provision of the Purchase Agreement or any
other Transaction Document, the perfection representations, warranties and
covenants contained in this Schedule I shall be continuing, and remain in full
force and effect until such time as all obligations under the Transaction
Documents and the Notes have been finally and fully paid and performed.

                                    NO WAIVER

     13. The parties to the Purchase Agreement shall provide the Rating Agencies
with prompt written notice of any breach of the perfection representations,
warranties and covenants contained in this Schedule I, and shall not, without
satisfying the Rating Agency Condition, waive a breach of any of such perfection
representations, warranties or covenants.
