assets described in Section 2.01(a), the Purchaser shall pay the Seller, in
immediately available funds, the Receivables Purchase Price. The Purchaser shall
deposit, from funds it receives from the issuance of the Securities, the Initial
Reserve Account Deposit into the Reserve Account, which amount shall be an asset

the Owner Trustee pursuant to the Sale and Servicing Agreement, all payments of
principal and interest on or in respect of the Receivables received after the
Cutoff Date.

         Section 2.03. Transfer of Receivables. Pursuant to the Sale and
Servicing Agreement, the Purchaser will assign all of its right, title and
interest in, to and under the Receivables and other assets described in Section
2.01(a) to the Issuer. The parties hereto acknowledge that the Issuer will
pledge its rights to and under the Receivables and other assets described in
Section 2.01(a) to the Indenture Trustee pursuant to the Trust Agreement. The
Purchaser has the right to assign its interest under this Agreement as may be
required to effect the purposes of the Sale and Servicing Agreement, without the
consent of the Seller, and the Owner Trustee as assignee shall succeed to the
rights and obligations hereunder of the Purchaser.

Receivable Files available to the Purchaser or its agent for examination during

              (c)  No Violation. The consummation of the transactions
         contemplated by this Agreement and the fulfillment of the terms hereof
         shall not conflict with, result in any breach of any of the terms and
         provisions of, nor constitute (with or without notice or lapse of time)
         a default under, the limited liability company agreement or certificate
         of formation of the Purchaser, or conflict with or breach any of the
         material terms or provisions of, or constitute (with or without notice
         or lapse of time) a default under, any indenture, agreement or other
         instrument to which the Purchaser is a party or by which it may be
         bound.

         Section 3.02. Representations and Warranties of CarMax.

         (a)  The Seller makes the representations and warranties contained in
Exhibit D attached hereto and incorporated herein by reference on which the
Purchaser relies in accepting the Receivables. The representations and
warranties of CarMax contained in Section 7.1 of the Sale and Servicing
Agreement are incorporated herein as if set forth herein and as if made to the
Purchaser on the date hereof.

         (b)  As of each Representation Date, the Seller Information is true and
accurate in all material respects and did not or does not contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

         (c)  It is understood and agreed that the representations and
warranties incorporated by reference in Section 3.02(a) or set forth in Section
3.02(b) shall remain operative and in full force and effect, shall survive the
transfer and conveyance of the Receivables and other assets described in Section
2.01(a) by the Seller to the Purchaser and by the Purchaser to the Issuer and
shall inure to the benefit of the Purchaser, the Trustees and the
Securityholders.

         (d)  The Seller shall indemnify the Purchaser and hold the Purchaser
harmless against any losses, penalties, fines, forfeitures, legal fees and
related costs, judgments and other costs and expenses resulting from any third
party claim, demand, defense or assertion based on or grounded upon, or
resulting from, a breach of the Seller's representations and warranties
incorporated by reference in Section 3.02(a) or set forth in Section 3.02(b).
The Trustees shall also have the remedies provided in the Sale and Servicing
Agreement.

         (e)  Any cause of action against the Seller relating to or arising out
of the breach of any of its representations and warranties made or incorporated
by reference in this Section shall accrue as to any Receivable upon (i)
discovery of such breach by the Purchaser or either Trustee or notice thereof by
the Seller to the Purchaser, (ii) failure by the Seller to cure such breach and
(iii) demand upon the Seller by the Purchaser for all amounts payable in respect
of such Receivable under this Agreement.

         (f)  The Purchaser or the Seller, as the case may be, shall inform the
other parties promptly, in writing, upon discovery of any breach of the Seller's
representations and warranties pursuant to this Section which materially and
adversely affects the interests of the Securityholders in any Receivable.

         (g)  If a breach of any representation or warranty incorporated by
reference in Section 3.02(a) which materially and adversely affects the
interests of the Purchaser, the Trust or the Securityholders in any Receivable
shall not have been cured by the close of business on the last day of the
Collection Period which includes the thirtieth day after the date on which the
Seller becomes aware of, or receives written notice from the Servicer, the
Purchaser, the Owner Trustee or the Insurer of such breach or failure, the
Seller shall repurchase such Receivable from the Trust on the Distribution Date
immediately following such Collection Period. In consideration for the
repurchase of any such Receivable, the Seller shall remit the Purchase Amount of
such Receivable to the Trust. Upon any such repurchase, the Purchaser shall,
without further action, be deemed to transfer, assign, set-over and otherwise
convey to the Seller, without recourse, representation or warranty, all the
right, title and interest of the Purchaser in, to and under such repurchased
Receivable and all other related assets described in Section 2.01(a). The
Purchaser, the Issuer, the Owner Trustee or the Indenture Trustee, as
applicable, shall execute such documents and instruments of transfer or
assignment and take such other actions as shall reasonably be requested by the
Seller to effect the conveyance of such Receivable pursuant to this Section. The
sole remedy of the Purchaser, the Issuer, the Trustees or the Securityholders
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
this Section.

                             COVENANTS OF THE SELLER

         Section 5.01. Protection of Right, Title and Interest in, to and Under
the Receivables.

         (a)  The Seller, at its expense, shall cause all financing statements
and continuation statements and any other necessary documents covering the
Purchaser's right, title and interest in, to and under the Receivables and other
property conveyed by the Seller to the Purchaser hereunder to be promptly
authorized, recorded, registered and filed, and at all times to be kept
recorded, registered and filed, all in such manner and in such places as may be
required by law fully to preserve and protect the right, title and interest of
the Purchaser hereunder to the Receivables and such other property. The Seller
shall deliver to the Purchaser file-stamped copies of, or filing receipts for,
any document recorded, registered or filed as provided above, as soon as
available following such recording, registration or filing. The Purchaser shall
cooperate fully with the Seller in connection with the obligations set forth
above and will execute any and all documents reasonably required to fulfill the
intent of this subsection.

         (b)  Within five days after the Seller makes any change in its name,
identity or organizational structure which would make any financing statement or
continuation statement filed in accordance with Section 4.01(d) seriously
misleading within the meaning of the UCC as in effect in the applicable state,
the Seller shall give the Purchaser notice of any such change and, within 30
days after such change, shall authorize and file such financing statements or
amendments as may be necessary to continue the perfection of the Purchaser's
security interest in the Receivables and the proceeds thereof.

         (c)  The Seller shall give the Purchaser written notice within five
days of any relocation of the state of organization of the Seller or any office
in which the Seller keeps records concerning the Receivables and whether, as a
result of such relocation, the applicable provisions of the UCC would require
the filing of any amendment of any previously filed financing or continuation
statement or of any new financing statement and, within 30 days after such
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
the Receivables and the proceeds thereof. The Seller shall at all times maintain
its state of organization, its principal place of business and its chief
executive office and the location of the office where the Receivables Files and
any accounts and records relating to the Receivables are kept within the United
States of America.

         (d)  The Seller shall maintain accounts and records as to each
Receivable accurately and in sufficient detail to permit (i) the reader thereof
to know at any time the status of such Receivable, including payments and
recoveries made and payments owing (and the nature of each) and (ii)
reconciliation between payments or recoveries on (or with respect to) each
Receivable.

         (e)  The Seller shall maintain its computer systems so that, from and
after the time of the transfer of the Receivables to the Purchaser pursuant to
this Agreement, the Seller's master computer records (including any back-up
archives) that refer to a Receivable shall indicate

                                       13

<PAGE>

clearly and unambiguously that such Receivable is owned by the Purchaser (or,
upon transfer of the Receivables to the Issuer, by the Issuer). Indication of
the Purchaser's ownership of a Receivable shall be deleted from or modified on
the Seller's computer systems when, and only when, such Receivable shall have
been paid in full or repurchased by the Seller.

         (f)  If at any time the Seller shall propose to sell, grant a security
interest in or otherwise transfer any interest in any motor vehicle retail
installment sale contract to any prospective purchaser, lender or other
transferee, the Seller shall give to such prospective purchaser, lender or other
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
during normal business hours to inspect, audit and make copies of and abstracts
from the Seller's records regarding any Receivable.

         (h)  If the Seller has repurchased one or more Receivables from the
Purchaser or the Issuer pursuant to Section 3.02(g), the Seller shall, upon
request, furnish to the Purchaser, within ten days, a list of all Receivables
(by receivable number and name of Obligor) then owned by the Purchaser, together
with a reconciliation of such list to the Receivables Schedule.

         Section 5.02. Security Interests. Except for the conveyances hereunder,
the Seller covenants that it will not sell, pledge, assign or transfer to any
other Person, or grant, create, incur, assume or suffer to exist any Lien on any
Receivable, whether now existing or hereafter created, or any interest therein;
the Seller will immediately notify the Purchaser of the existence of any Lien on
any Receivable and, in the event that the interests of the Securityholders in
such Receivable are materially and adversely affected, such Receivable shall be
repurchased from the Purchaser by the Seller in the manner and with the effect
specified in Section 3.02(g), and the Seller shall defend the right, title and
interest of the Purchaser in, to and under the Receivables, whether now existing
or hereafter created, against all claims of third parties claiming through or
under the Seller.

         Section 5.03. Delivery of Payments. The Seller covenants and agrees to
deliver in kind upon receipt to the Servicer under the Sale and Servicing
Agreement all payments received by the Seller in respect of the Receivables as
soon as practicable after receipt thereof by the Seller.

         Section 5.04. No Impairment. The Seller covenants that it shall take no
action, nor omit to take any action, which would impair the rights of the
Purchaser in any Receivable, nor shall it, except as otherwise provided in this
Agreement or the Sale and Servicing Agreement, reschedule, revise or defer
payments due on any Receivable.

         Section 5.05. Costs and Expenses. The Seller shall pay all reasonable
costs and expenses incurred in connection with the perfection of the Purchaser's
right, title and interest in, to and under the Receivables.

<PAGE>

         Section 5.06. Hold Harmless. The Seller shall protect, defend,
indemnify and hold the Purchaser and the Issuer and their respective assigns and
their attorneys, accountants, employees, officers and directors harmless from
and against all losses, costs, liabilities, claims, damages and expenses of
every kind and character, as incurred, resulting from or relating to or arising
out of (i) the inaccuracy, nonfulfillment or breach of any representation,
warranty, covenant or agreement made by CarMax in this Agreement, (ii) any legal
action, including any counterclaim, that has either been settled by the
litigants (which settlement, if the Seller is not a party thereto shall be with
the consent of the Seller) or has proceeded to judgment by a court of competent
jurisdiction, in either case to the extent it is based upon alleged facts that,
if true, would constitute a breach of any representation, warranty, covenant or
agreement made by the Seller in this Agreement, (iii) any actions or omissions
of the Seller or any employee or agent of the Seller occurring prior to the
Closing Date with respect to any Receivable or Financed Vehicle or (iv) any
failure of a Receivable to be originated in compliance with all requirements of
law. These indemnity obligations shall be in addition to any obligation that the
Seller may otherwise have.

         Section 5.07. Merger, Consolidation or Assumption of the Obligations of
the Seller. The Seller shall not transfer or otherwise assign its obligations as
Servicer under the Sale and Servicing Agreement nor enter into any merger,
conversion or consolidation to which the Servicer is a party, unless the Insurer
shall otherwise consent in writing to any such transfer, assignment or
succession; provided, however, that the consent of the Insurer shall not be
required if the Servicer shall be the surviving entity in any such merger,
conversion or consolidation.

                                 INDEMNIFICATION

         Section 6.01. Indemnification.

         (a)  The Seller agrees to indemnify and hold harmless the Purchaser,
each Underwriter and each person, if any, who controls the Purchaser or any
Underwriter within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act as follows:

              (i)    against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact included in the Seller
         Information or any similar information contained in the Preliminary
         Prospectus or the Prospectus or any amendment or supplement thereto, or
         the omission or alleged omission from the Seller Information or such
         similar information of 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

<PAGE>

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 June 1, 2002 (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 or an Affiliate of 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 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
the lapse of time or both would constitute a default, breach, violation or event
permitting acceleration under the terms of any Receivable has arisen and the
Seller has not waived any such event or condition.

         (l)  Title. The Seller intends that the transfer of the Receivables
contemplated by Section 2.01(a) of the Receivables Purchase Agreement constitute
a sale of the Receivables from

                                      D-2

<PAGE>

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. With respect to each Receivable, the Seller has
taken all steps necessary to perfect its security interest against the related
Obligor in the related Financed Vehicle. 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.

         (n)  Financing Statements. All financing statements filed or to be
filed against the Seller in favor of the Trust (as assignee of the Depositor)
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 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
subject to the laws of, any jurisdiction under which the sale, transfer,
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.

         (p)  One Original. There is only one original executed copy of each
Receivable.

                                      D-3

         Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to them in the Indenture dated as of June 1, 2002
between the Trust and the Indenture Trustee (the "Agreement"). As used herein,

         Noteholders or the Certificateholders with respect to such Distribution
         Date.

         As used herein, the term "Net Principal Policy Amount" shall mean, on
any Distribution Date, the sum of the Note Balance as of the Closing Date plus
the Certificate Balance as of the Closing Date, minus all amounts previously
drawn on the Policy or withdrawn from the Reserve Account in either case with
respect to Monthly Note Principal or Monthly Certificate Principal.

         As used herein, the term "Insurance Agreement" shall mean the Insurance
and Reimbursement Agreement, dated as of June 26, 2002 among Pooled Auto
Securities Shelf LLC (the "Depositor"), CarMax Auto Superstores, Inc.,
individually, as seller (the "Seller") and as servicer (the "Servicer") and
MBIA.

         As used herein, the term "Insolvency Proceeding" means (i) the
commencement, after the date hereof, of any bankruptcy, insolvency, readjustment
of debt, reorganization, marshalling of assets and liabilities or similar
proceedings by or against the Seller, the Servicer, the Depositor or the Trust,
or (ii) the commencement, after the date hereof, of any proceedings by or
against the Seller, the Servicer, the Depositor or the Trust for the winding up
or liquidation of its affairs or (iii) the consent, after the date hereof, to
the appointment of a trustee, conservator, receiver, or liquidator in any
bankruptcy, insolvency, readjustment of debt, reorganization, marshalling of
assets and liabilities or similar proceedings of or relating to the Seller, the

         Subject to the foregoing, if any amount paid or required to be paid in
respect of the Insured Obligation is voided (a "Preference Event") under any
applicable bankruptcy, insolvency, receivership or similar law in an Insolvency
Proceeding, and, as a result of such a Preference Event, the Beneficiary, the
Noteholders or the Certificateholders are required to return such voided
payment, or any portion of such voided payment made or to be made in

                                       2

<PAGE>

respect of the Notes or the Certificates, respectively (an "Avoided Payment"),
MBIA will pay an amount equal to each such Avoided Payment, irrevocably,
absolutely and unconditionally and without the assertion of any defenses to
payment, including fraud in inducement or fact or any other circumstances that
would have the effect of discharging a surety in law or in equity, upon receipt
by MBIA from the Beneficiary, the Noteholders or the Certificateholders of (x) a
certified copy of a final order of a court exercising jurisdiction in such
Insolvency Proceeding to the effect that the Beneficiary, the Noteholders or the
Certificateholders are required to return any such payment or portion thereof
prior to the Termination Date (as defined below) of this Policy because such
payment was voided under applicable law, with respect to which order the appeal
period has expired without an appeal having been filed (the "Final Order"), (y)
an assignment, in the form of Exhibit D hereto, irrevocably assigning to MBIA
all rights and claims of the Beneficiary, the Noteholders or the
Certificateholders relating to or arising under such Avoided Payment and (z) a
Notice for Payment in the form of Exhibit A hereto appropriately completed and
executed by the Beneficiary, the Noteholders or the Certificateholders. Such
payment shall be disbursed to the receiver, conservator, debtor-in-possession or
trustee in bankruptcy named in the Final Order and not to the Beneficiary, the
Noteholders or the Certificateholders directly unless such Noteholder or such
Certificateholder (as the case may be) has returned principal and interest paid
on the Notes or the Certificates (as the case may be) to such receiver,
conservator, debtor-in-possession or trustee in bankruptcy, in which case such
payment shall be disbursed to such Noteholder or such Certificateholder (as the
case may be).

         Notwithstanding the foregoing, in no event shall MBIA be obligated to
make any payment in respect of any Avoided Payment, which payment represents a
payment of interest or the principal amount of the Notes or the Certificates,
prior to the time MBIA would have been required to make a payment in respect of
such interest or principal pursuant to the first paragraph of this Policy.

         Payment of amounts hereunder shall be made in immediately available
funds (x) pursuant to the first paragraph of this Policy on the later of (a)
12:00 noon, New York City time, on the Distribution Date or (b) 12:00 noon, New
York City time, on the Business Day next succeeding presentation to MBIA and
State Street Bank and Trust Company, N.A., as Fiscal Agent for MBIA or any
successor fiscal agent appointed by MBIA (the "Fiscal Agent") (as hereinafter
provided) of a notice for payment in the form of Exhibit A hereto ("Notice for
Payment"), appropriately completed and executed by the Beneficiary, and (y) in
respect of Avoided Payments prior to 12:00 noon New York City time, on the
second Business Day following MBIA's receipt of the documents required under
clauses (x) through (z) of the second preceding paragraph. Any such documents
received by MBIA or the Fiscal Agent after 12:00 noon New York City time on any
Business Day or on any day that is not a Business Day shall be deemed to have
been received by MBIA or the Fiscal Agent, as applicable, prior to 12:00 noon on
the next succeeding Business Day. All payments made by MBIA hereunder will be
made with MBIA's own funds. A Notice for Payment under this Policy may be
presented to the Fiscal Agent and MBIA on any Business Day following the
Determination Date in respect of which the Notice for Payment is being
presented, by (a) delivery of the original Notice for Payment to the Fiscal
Agent and MBIA at its respective addresses set forth below, or (b) facsimile
transmission of the original Notice for Payment to the Fiscal Agent and MBIA at
its respective facsimile numbers set forth below. If presentation is made by
facsimile transmission, the Beneficiary shall (i) simultaneously confirm
transmission by telephone to the Fiscal Agent and MBIA at its respective
telephone numbers set forth below, and (ii) as soon as reasonably practicable,
deliver

                                       3

<PAGE>

the original Notice for Payment to the Fiscal Agent and MBIA at its respective
addresses set forth below.

         If any Notice for Payment received by the Fiscal Agent is not in proper
form or is otherwise insufficient for the purpose of making a claim hereunder,
it shall be deemed not to have been received by the Fiscal Agent and MBIA, and
MBIA or the Fiscal Agent, shall promptly so advise the Indenture Trustee, and
the Indenture Trustee may submit an amended Notice for Payment.

         Payments due hereunder unless otherwise stated herein will be disbursed
by the Fiscal Agent or MBIA to the Indenture Trustee on behalf of the
Noteholders and the Certificateholders by wire transfer of immediately available
funds in the amount of such payment.

         The Fiscal Agent is the agent of MBIA only, and the Fiscal Agent shall
in no event be liable to the Noteholders or the Certificateholders for any acts
of the Fiscal Agent or any failure of MBIA to deposit or cause to be deposited
sufficient funds to make payments due under this Policy.

         MBIA hereby waives and agrees not to assert any and all rights to
require the Beneficiary to make demand on or to proceed against any person,
party or security prior to the Beneficiary demanding payment under this Policy.

         No defenses, set-offs and counterclaims of any kind available to MBIA
so as to deny payment of any amount due in respect of this Policy will be valid
and MBIA hereby waives and agrees not to assert any and all such defenses,
set-offs and counterclaims, including, without limitation, any such rights
acquired by subrogation, assignment or otherwise.

         MBIA shall be subrogated to the rights of the Noteholders and the
Certificateholders to receive payments under the Notes and the Certificates to
the extent of any payment by MBIA hereunder.

         Any rights of subrogation acquired by MBIA as a result of any payment
made under this Policy shall, in all respects, be subordinate and junior in
right of payment to the prior indefeasible payment in full of all amounts due
the Noteholders and the Certificateholders under the Notes and the Certificates.
MBIA's obligations under this Policy shall be discharged to the extent funds to
pay the Insured Obligation are deposited into the Collection Account, the Note
Payment Account or the Certificate Payment Account by the Servicer or the
Indenture Trustee, as applicable, in accordance with the Sale and Servicing
Agreement (except to the extent such payment is thereafter returned as an
Avoided Payment) or disbursed by MBIA as provided in this Policy, whether or not
such funds are properly applied by the Owner Trustee or the Beneficiary.

         This Policy is neither transferable nor assignable, in whole or in
part, except to a successor trustee duly appointed and qualified under the
Agreement. Such transfer and assignment shall be effective upon receipt by MBIA
of a copy of the instrument effecting such transfer and assignment signed by the
transferor and by the transferee, and a certificate, properly completed and
signed by the transferor and the transferee, in the form of Exhibit B hereto
(which shall be conclusive evidence of such transfer and assignment), and, in
such case, the transferee instead of the transferor shall, without the necessity
of further action, be entitled to all the benefits of and rights under this
Policy in the transferor's place, provided that, in such case, the Notice for
Payment presented hereunder shall be a certificate of the transferee and shall
be signed by one who states therein that he is a duly authorized officer of the
transferee.
