with respect to a breach of the Seller's representations and warranties pursuant
to Section 3.02(a) or with respect to the existence of any such Liens or claims
shall be to require the Seller to repurchase the related Receivables pursuant to

relocation, shall authorize and file such financing statements or amendments as
may be necessary to continue the perfection of the interest of the Purchaser in

transferee computer tapes, compact disks, records or print-outs (including any
restored from back-up archives) that, if they shall refer in any manner
whatsoever to any Receivable, shall indicate clearly and unambiguously that such
Receivable has been sold and is owned by the Purchaser (or, upon transfer of the
Receivables to the Issuer, the Issuer), unless such Receivable has been paid in
full or repurchased by the Seller.

        (g)     The Seller shall permit the Purchaser and its agents at any time

succession; provided, however, that the consent of the Insurer shall not be
required if (i) the Servicer shall be the surviving entity in any such merger,
conversion or consolidation or (ii) Circuit City Stores, Inc. shall, in
connection with such transfer or other assignment or such merger, conversion or

     a material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever, based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     6.01(c)) any such settlement is effected with the written consent of the
     Seller; and

          (iii) against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Purchaser or the
     Representative), reasonably incurred in investigating, preparing or
     defending against any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or any claim
     whatsoever, based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under clause (i) or (ii) above.

     (b)  Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
hereunder to the extent it is not materially prejudiced as a result thereof and
in any event shall not relieve it from any liability which it may have otherwise
than on account of this indemnity agreement. Counsel to the indemnified parties
shall be selected by the Purchaser or the Representative, subject to the consent
of the indemnifying party (which consent shall not be unreasonably withheld). An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for fees
and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or

                                       16

circumstances. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

     (c)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6.01(a)(ii) effected without
its written consent if (i) such settlement is entered into more than 45 days
after receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement; provided,
however, that such indemnifying party shall not be liable for such settlement if
it has notified the indemnified party in writing that it objects to the terms of
such settlement within 30 days after receipt of the notice described in clause
(ii) above or that it objects to the requested fees and expenses within 45 days
after receipt of such request.

     (d)  If recovery is not available under the provisions of this Section for
any reason other than as specified herein, the parties entitled to
indemnification by the terms hereof shall be entitled to contribution to
liabilities and expenses, except to the extent that contribution is not
permitted under Section 11(f) of the Securities Act. In determining the amount
of contribution to which the respective parties are entitled, there shall be
considered the relative benefits received by each party, the parties' relative
knowledge and access to information concerning the matter with respect to which
the claim was asserted, the opportunity to correct and prevent any statement or
omission, and any other equitable considerations appropriate under the
circumstances. The parties hereto agree that it would not be equitable if the
amount of such contribution were determined by pro rata or per capita allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section. The aggregate amount
of losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section shall be deemed to include any legal
or other expenses reasonably incurred by such indemnified party in
investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever, based upon any such untrue or alleged
untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
underwriting discounts and commissions received by it in connection with the
Securities underwritten by it and distributed to the public exceeds the amount
of any damages which such Underwriter has otherwise been required to pay by
reason of any such untrue or alleged untrue statement or omission or alleged
omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     CarMax Auto Superstores, Inc., a Virginia corporation (the "Seller"), makes
the following representations and warranties in the Receivables Purchase
Agreement dated as of November 1, 2001 (the "Receivables Purchase Agreement")
between the Seller and Pooled Auto Securities Shelf LLC, a Delaware limited
liability company (the "Depositor"). All capitalized terms used in such
representations and warranties have the respective meanings assigned to them in
the Receivables Purchase Agreement.

     (a)  Characteristics of Receivables. Each Receivable (i) has been
          ------------------------------
originated by the Seller in the ordinary course of business in connection with
the sale of a new or used motor vehicle and has been fully and properly executed
by the parties thereto, (ii) contains customary and enforceable provisions such
that the rights and remedies of the holder thereof are adequate for realization
against the collateral of the benefits of the security, (iii) provides for level
monthly payments that fully amortize the Amount Financed by maturity (except
that the period between the date of such Receivable and the date of the first
Scheduled Payment may be less than or greater than one month and the amount of
the first and last Scheduled Payments may be less than or greater than the level
payments) and yield interest at the related APR, (iv) provides for, in the event
that such Receivable is prepaid, a prepayment that fully pays the Principal
Balance of such Receivable with interest at the related APR through the date of
payment, (v) is a retail installment sale contract substantially in the form of
Exhibit E to the Receivables Purchase Agreement, (vi) is secured by a new or
used motor vehicle that had not been repossessed as of the Cutoff Date, (vii) is
a Simple Interest Receivable, (viii) relates to an Obligor who has made at least
one (1) payment under such Receivable as of the Cutoff Date and (ix) relates to
an Obligor whose mailing address is located in any State.

     (b)  Receivable Schedule. The information set forth in the Receivable
          -------------------
Schedule was true and correct in all material respects as of the opening of
business on the Cutoff Date, and no selection procedures believed to be adverse
to the Depositor, the Noteholders and/or the Certificateholders were utilized in
selecting the Receivables from those retail installment sale contracts which met
the criteria contained in the Receivables Purchase Agreement. The information
set forth in the compact disk or other listing regarding the Receivables made
available to the Depositor and its assigns (which compact disk or other listing
is required to be delivered as specified herein) is true and correct in all
material respects.

     (c)  Compliance with Law. Each Receivable and the sale of the related
          -------------------
Financed Vehicle complied, at the time such Receivable was originated and
complies, as of the Closing Date, in all material respects with all requirements
of applicable federal, state and local laws, and regulations thereunder,
including usury laws, the Federal Truth-in-Lending Act, the Equal Credit
Opportunity Act, the Fair Credit Reporting Act, the Fair Credit Billing Act, the
Fair Debt Collection Practices Act, the Federal Trade Commission Act, the
Magnuson-Moss Warranty Act, the Federal Reserve Board's Regulations B, M and Z,
the Soldiers' and Sailors' Civil Relief Act of 1940 and state adaptations of the
National Consumer Act and the Uniform Consumer Credit Code.

                                       D-1

<PAGE>

        (d)     Binding Obligation. Each Receivable represents the genuine,
                ------------------
legal, valid and binding payment obligation in writing of the related Obligor,
enforceable by the holder thereof in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
liquidation or other similar laws affecting the enforcement of creditors' rights
generally and by general principles of equity.

        (e)     No Government Obligor.  No Receivable is due from the United
                ---------------------
States of America or any State or from any agency, department or instrumentality
of the United States of America or any State.

        (f)     Security Interest in Financed Vehicles. Immediately prior to the
                --------------------------------------
transfer of the Receivables by the Seller to the Depositor, each Receivable was
secured by a valid, binding and enforceable first priority perfected security
interest in favor of the Seller in the related Financed Vehicle, which security
interest has been validly assigned by the Seller to the Depositor. The Servicer
has received, or will receive within 180 days after the Closing Date, the
original certificate of title for each Financed Vehicle (other than any Financed
Vehicle that is subject to a certificate of title statute or motor vehicle
registration law that does not require that the original certificate of title
for such Financed Vehicle be delivered to the Seller).

        (g)     Receivables in Force. No Receivable has been satisfied,
                --------------------
subordinated or rescinded, nor has any Financed Vehicle been released in whole
or in part from the Lien granted by the related Receivable.

        (h)     No Waiver.  No provision of any Receivable has been waived in
                ---------
such a manner that such Receivable fails to meet all of the representations and
warranties made by the Seller in this Exhibit D with respect thereto.

        (i)     No Defenses. No Receivable is subject to any right of
                -----------
rescission, setoff, counterclaim or defense, including the defense of usury, and
the operation of any of the terms of any Receivable, or the exercise of any
right thereunder, will not render such Receivable unenforceable in whole or in
part or subject to any right of rescission, setoff, counterclaim or defense,
including the defense of usury, and the Seller has not received written notice
of the assertion with respect to any Receivable of any such right of rescission,
setoff, counterclaim or defense.

        (j)     No Liens. To the best of the Seller's knowledge, no liens or
                --------
claims have been filed for work, labor or materials or for unpaid state or
federal taxes relating to any Financed Vehicle that are prior to, or equal or
coordinate with, the security interest in such Financed Vehicle created by the
related Receivable.

        (k)     No Default; Repossession. To the best of the Seller's knowledge,
                ------------------------
no default, breach, violation or event permitting acceleration under the terms
of any Receivable has occurred and no continuing condition that with notice or

        (l)     Title.  The Seller intends that the transfer of the Receivables

the Seller to the Depositor and that the beneficial interest in, and title to,
the Receivables not be part of the Seller's estate in the event of the filing of
a bankruptcy petition by or against the Seller under any bankruptcy law. The
Seller has not sold, transferred, assigned or pledged any Receivable to any
Person other than the Depositor. Immediately prior to the transfer of the
Receivables contemplated by Section 2.01(a) of the Receivables Purchase
Agreement, the Seller had good and marketable title to the Receivables free and
clear of any Lien, claim or encumbrance of any Person and, immediately upon such
transfer, the Depositor shall have good and marketable title to the Receivables
free and clear of any Lien, claim or encumbrance of any Person.

        (m)     Security Interest Matters. The Receivables Purchase Agreement
                -------------------------
creates a valid and continuing "security interest" (as defined in the Relevant
UCC) in the Receivables in favor of the Depositor, which security interest is
prior to all other Liens and is enforceable as such as against creditors of and
purchasers from the Seller. The Receivables constitute "tangible chattel paper"
(as defined in the Relevant UCC). The Seller has caused or will cause prior to
the Closing Date the filing of all appropriate financing statements in the
proper filing offices in the appropriate jurisdictions under applicable law
necessary to perfect the security interest in the Receivables granted to the
Depositor under the Receivables Purchase Agreement. Other than the security
interest granted to the Depositor under the Receivables Purchase Agreement, the
Seller has not pledged, assigned, sold, granted a security interest in or
otherwise conveyed any of the Receivables. The Seller has not authorized the
filing of and is not aware of any financing statements against the Seller that
include a description of collateral covering the Receivables other than any
financing statement relating to the security interest granted to the Depositor
under the Sale and Servicing Agreement or that has been terminated. The motor
vehicle retail installment sale contracts that constitute or evidence the
Receivables do not have any marks or notations indicating that they have been
pledged, assigned or otherwise conveyed to any Person other than the Depositor,
the Trust or the Indenture Trustee. The Seller is not aware of any judgment or
tax lien filings against the Seller.

                --------------------

security interest in any collateral described in this financing statement will
violate the rights of the Trust." All financing statements filed or to be filed
against the Seller in favor of the Indenture Trustee (as assignee of the Trust)
contain a statement substantially to the following effect: "A purchase of or
security interest in any collateral described in this financing statement will
violate the rights of the Indenture Trustee."

        (o)     Valid Assignment. No Receivable has been originated in, or is

assignment and conveyance of such Receivable under the Receivables Purchase
Agreement or the Sale and Servicing Agreement or the pledge of such Receivable
under the Indenture is unlawful, void or voidable or under which such Receivable
would be rendered void or voidable as a result of any such sale, transfer,
assignment, conveyance or pledge. The Seller has not entered into any agreement
with any account debtor that prohibits, restricts or conditions the assignment
of the Receivables.
