                             COVENANTS OF SELLERS

          .1   Liens in Force. The Financed Vehicle securing each Receivable
               --------------
shall not be released by the related Seller in whole or in part from the
security interest granted under the Receivable, except upon payment in full of
the Receivable or as otherwise contemplated herein or the Related Documents and
the related Seller shall not take or permit any action inconsistent with the
foregoing.

                                       9

 
          .2   No Impairment.  The related Seller shall do nothing to impair the
               -------------
rights of the Purchaser or the Secured Parties in the Receivables, the Dealer
Agreements, the Dealer Assignments, the Insurance Policies or any other property
or interest comprising the Other Conveyed Property.

          .3   No Amendments. The Sellers shall not take or permit any action to
               -------------
extend or otherwise amend the terms of any Receivable, except in accordance with
the Related Documents.

          .4   Restrictions on Liens. The Sellers shall not: (i) create or incur
               ---------------------
or agree to create or incur, or consent to cause (upon the happening of a
contingency or otherwise) the creation, incurrence or existence of any Lien or
restriction on transferability of the Receivables or of any Other Conveyed
Property except for the Lien in favor of the Purchaser and the Collateral Agent
as assignee thereof, and the restrictions on transferability imposed by this
Agreement or (ii) sign or file under the Uniform Commercial Code of any
jurisdiction any financing statement or sign any security agreement authorizing
any secured party thereunder to file such financing statement, with respect to
the Receivables or to any Other Conveyed Property, except in each case any such
instrument solely securing the rights and preserving the Lien of the Purchaser
and the Collateral Agent as assignee thereof. The Sellers will take no action to
cause any Receivable to be evidenced by an instrument (as such term is defined
in the relevant UCC).

          .5   Preservation of Collateral. The Sellers will do, execute,
          -------------------------------
acknowledge and deliver, or cause to be done, executed, acknowledged and
delivered, such instruments of transfer or take such other steps or actions as
may be necessary, or required by the Purchaser or the Collateral Agent or the
Agent, to effect the Conveyance, to perfect the security interest granted in the
Receivables and the Other Conveyed Property to the Collateral Agent on behalf of
the Secured Parties, to ensure that such Conveyance and security interest ranks
prior to all other Liens and to preserve the priority of such Conveyance and
security interest and the validity and enforceability thereof.

                                  ARTICLE V.

                                  REPURCHASES

          .1   Repurchase of Receivables Upon Breach of Warranty. Upon the
          ------------------------------------------------------
occurrence of a Repurchase Event, AFS shall, unless the breach which is the
subject of such Repurchase Event shall have been cured in all material respects,
repurchase the Receivable relating thereto (whether or not it was the Seller
thereof) from the Purchaser and, simultaneously with the repurchase of the
Receivable, AFS shall deposit the Purchase Amount in full, without deduction or
offset, to the Collection Account, pursuant to Section 8.18 of the Receivables
Financing Agreement. It is understood and agreed that the obligation of AFS to
repurchase any Receivable, as to which a breach has occurred and is continuing,
shall, if such obligation is fulfilled, constitute the sole remedy against AFS,
ACC or AFC for such breach available to Purchaser, the Backup Servicer, the
Noteholder, the Certificateholders or the Collateral Agent on behalf of the
Secured Parties. The provisions of this Section 5.1 are intended to grant the
Collateral Agent and the Agent a direct right against AFS to demand performance
hereunder, and in connection

                                      10

 
therewith, AFS waives any requirement of prior demand against Purchaser with
respect to such repurchase obligation. Any such repurchase shall take place in
the manner specified in Section 8.7 of the Receivables Financing Agreement.
Notwithstanding any other provision of this Agreement or the Receivables
Financing Agreement to the contrary, the obligation of AFS under this Section
shall not terminate upon a termination of AFS as Servicer under the Receivables
Financing Agreement and shall be performed in accordance with the terms hereof
notwithstanding the failure of the Servicer or Purchaser to perform any of their
respective obligations with respect to such Receivable under the Receivables
Financing Agreement.

          .2   Reassignment of Purchased Receivables. Upon deposit in the
          ------------------------------------------
Collection Account of the Purchase Amount of any Receivable repurchased by AFS
under Section 5.1 hereof, Purchaser (at AFS's expense) shall take such steps as
may be reasonably requested by AFS in order to assign to AFS all of Purchaser's
and the Collateral Agent's right, title and interest in and to such Receivable
and all security and documents and all Other Conveyed Property conveyed to
Purchaser and the Collateral Agent directly relating thereto, without recourse,
representation or warranty, except as to the absence of Liens created by or
arising as a result of actions of Purchaser or the Collateral Agent. Such
assignment shall be a sale and assignment outright, and not for security. If,
following the reassignment of a Purchased Receivable, in any enforcement suit or
legal proceeding, it is held that AFS may not enforce any such Receivable on the
ground that it shall not be a real party in interest or a holder entitled to
enforce the Receivable, Purchaser and the Collateral Agent shall, at the expense
of AFS, take such steps as AFS deems reasonably necessary to enforce the
Receivable, including bringing suit in Purchaser's or in the Collateral Agent's
name.

          .3   Waivers. No failure or delay on the part of Purchaser, or the
          ------------
Collateral Agent as assignee of Purchaser, in exercising any power, right or
remedy under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude any other
or future exercise thereof or the exercise of any other power, right or remedy.

                                  ARTICLE VI.

                             CONDITIONS PRECEDENT

          (d)  the Sellers shall take any action (including, but not limited to,
     the filing of appropriate UCC financing statements) required to perfect the
     ownership interest of the Purchaser in the Receivables and the Other
     Conveyed Property (provided, however, that the Sellers shall make such

     promptly provide to each of the Purchaser and the Collateral Agent and the
     Agent a copy of a stamped acknowledgement copy thereof);

          (e)  such sale or contribution shall be reflected on the books and
     records of the Trust pursuant to Section 5.1; and

          (f)  to the extent that, after giving effect to the sale and/or
     contribution of Receivables made on such date there would be one or more
     states of the United States in which Financed Vehicles securing more than
     10% of the Pool Balance were titled and as to which states an Opinion of
     Counsel had not been given on the Effective Date or on a prior Receivables
     Transfer Date as to the perfection, priority and enforceability of the
     Collateral Agent's security interest for each such state, AFS shall have
     caused to be delivered to the Purchaser, the Collateral Agent and the Agent
     such an Opinion of Counsel;

          (g)  prior to first sale/and or contribution of Receivables by ACC,
     legal opinions of (i) the General Counsel of ACC, (ii) Texas counsel, (iii)
     California counsel and (iv) such other counsel as may be required by the
     Agent, the Collateral Agent and/or the Rating Agencies, each in form and
     substance satisfactory to the Agent covering such matters as the agent may
     reasonably request shall be delivered to the Purchaser, the Collateral
     Agent and the Agent; and

          (h)  the Purchaser and the Collateral Agent shall have received lien
     releases duly executed and delivered by Wells Fargo Bank (Texas), National
     Association with respect to the Receivables to be sold or contributed.

                                 ARTICLE VII.

                                 MISCELLANEOUS

          .1   Liability of Sellers. Sellers shall be liable in accordance
          -------------------------

document or any further action by any of the parties to this Agreement.

          .3   Limitation on Liability of Sellers and Others. Each Seller and

         REPRESENTATIONS AND WARRANTIES FROM AFS AS TO THE RECEIVABLES
         -------------------------------------------------------------

               Each Receivable that (i) was originated by AFS or ACC directly or
by a Dealer for the retail sale or refinancing of a Financed Vehicle in the
ordinary course of its business and such Seller or Dealer (as the case may be)
had all necessary licenses and permits to originate Receivables in the
applicable state, and, if originated by a Dealer, was purchased by AFS or ACC
from such Dealer under a Dealer Agreement or pursuant to a Dealer Assignment and
was validly assigned by such Dealer to such Seller, or, with respect to any
Receivable sold to the Purchaser by AFC, was purchased by AFC from AFS or ACC,
(ii) has created or shall create a valid, subsisting and enforceable first
priority perfected security interest in favor of AFS or ACC in the related
Financed Vehicle (which security interest has been assigned to the Purchaser and
shall be validly assignable by the Purchaser to the Collateral Agent on behalf
of the Secured Parties), except as enforceability may be limited by bankruptcy,
insolvency, reorganization or similar laws affecting the enforcement of
creditors' rights generally, (iii) was fully and properly executed by the
parties thereto and contains customary and enforceable provisions such as to
render the rights and remedies of the holder thereof adequate for realization
against the collateral security, (iv) is a Simple Interest Receivable or Pre-
Computed Receivable which provides for level monthly payments (provided that the
                                                               --------
payment in the first monthly period and the final monthly period of the life of
the Receivable may be minimally different from the level payment) which, if made
when due, shall fully amortize the Amount Financed over the original term, (v)
provides for, in the event that such contract is prepaid, a prepayment that
fully pays the principal balance and includes accrued but unpaid interest
through the date of prepayment in an amount at least equal to the Annual
Percentage Rate, and (vi) except to the extent permitted by this Agreement or
the Receivables Financing Agreement, has not been amended, waived or rewritten
or collections with respect thereto deferred or waived; and

          (1) with respect to which all requirements of applicable federal,
     state and local laws, and regulations thereunder (including, without
     limitation, usury laws, the Federal Truth-in-Lending Act, the Equal Credit
     Opportunity Act, the Fair Credit Billing Act, the Fair Credit Reporting
     Act, the Fair Debt Collection Practices Act, the Federal Trade Commission
     Act, the Magnuson-Moss Warranty Act, the Federal Reserve Board's
     Regulations 'B' and 'Z', the Soldiers' and Sailors' Civil Relief Act of
     1940, and state adaptations of the National Consumer Act and of the Uniform
     Consumer Credit Code and other consumer credit laws and equal credit
     opportunity and disclosure laws), in respect of such Receivable, the sale
     of the Financed Vehicle related thereto and the sale of credit life and
     credit accident and health insurance and any extended service contracts, if
     any, in connection with such Receivable, have been complied with in all
     material respects;

          (2) that is a Dollar obligation of an Obligor domiciled in the United
     States of America and that was originated and, if originated by a Dealer,
     was sold by the 

                                     S-A-1

 
     Dealer to AFS or ACC, without any fraud or material misrepresentation on
     the part of such Dealer or on the part of the Obligor;

          (3) which represents the genuine, legal, valid and binding payment
     obligation of the Obligor thereon, enforceable by the holder thereof in
     accordance with its terms, except (A) as enforceability may be limited by
     bankruptcy, insolvency, reorganization or similar laws affecting the
     enforcement of creditors' rights generally and by equitable limitations on
     the availability of specific remedies, regardless of whether such
     enforceability is considered in a proceeding in equity or at law and (B) as
     such Receivable may be modified by the application of the Soldiers' and
     Sailors' Civil Relief Act of 1940, as amended; and all parties to such
     Receivable had full legal capacity to execute and deliver such Receivable
     and all other documents related thereto and to grant the security interest
     purported to be granted thereby;

          (4) which is not due from the United States of America or any State or
     from any agency, department, subdivision or instrumentality thereof;

          (5) with respect to which the information set forth in the Schedule of
     Receivables has been produced from AFS's and, to the extent it maintains
     separate computer records, AFC's or ACC's (as the case may be) electronic
     ledger and was true and correct in all material respects, and is a complete
     and accurate description, on the relevant Receivables Transfer Date, of the
     Receivables sold to the Purchaser on such date; and with respect to which,
     on or prior to the relevant Receivables Transfer Date, AFS and, to the
     extent it maintains separate computer records, AFC or ACC (as the case may
     be) has appropriately marked its computer records to indicate the sale to
     the Purchaser of the Receivables sold on such date and with respect to
     which the Monthly Tape delivered by the Servicer to the Backup Servicer
     from time to time was complete and accurate as of the date delivered and
     consistent with the information set forth in the Schedule of Receivables
     with respect to such Receivable;

          (6) which (i) as of the related Advance Date, (A) had an original
     maturity of at least 6 months but not more than 72 months, (B) had an
     original Amount Financed of at least $1,000 and not more than $50,000, (C)
     had an Annual Percentage Rate of at least 7.75% and not more than 27.0%,
     and (D) was not more than 30 days past due; and (ii) with respect to which
     no funds have been advanced with respect to such Receivable by the
     Purchaser, a Seller, the Servicer, any Dealer, or anyone acting on behalf
     of any of them in order to cause such Receivable to qualify under subclause
                                                                       ---------
     (i)(D) of this clause (f);
     ------         ---------- 

          (7) which has not been satisfied, subordinated or rescinded, and the
     Financed Vehicle securing such Receivable has not been released from the
     Lien of such Receivable in whole or in part;

                                     S-A-2

 
          (8) with respect to which no provision has been waived (except to the
     extent permitted by this Agreement or the Receivables Financing Agreement);

          (9) except for any Lien granted by the Wells Fargo Documents (as
     defined in the Intercreditor Agreement) which Lien shall be released on the
     applicable Receivables Transfer Date, as to which neither any Seller nor
     the Purchaser has done anything to convey any right to any Person that
     would result in such Person having a right to payments due under such
     Receivable or otherwise to impair the rights of the Collateral Agent on
     behalf of the Secured Parties in such Receivable or the proceeds thereof;

          (10) which has not been sold, transferred, assigned or pledged by the
     Purchaser to any Person other than hereunder; and no Dealer has a
     participation in, or other right to receive, proceeds of such Receivable
     and with respect to which neither AFS nor the Purchaser has taken any
     action to convey any right to any Person (other than hereunder) that would
     result in such Person having a right to payments received under the related
     Insurance Policy or the related Dealer Agreement or Dealer Assignment or to
     payments due under such Receivable;

          (11) which is not subject to any right of rescission, setoff,
     counterclaim or defense and no such right has been asserted or, to the
     knowledge of the Purchaser or of any Seller, threatened with respect
     thereto;

          (12) with respect to which no liens or claims have been filed for
     work, labor or materials relating to a Financed Vehicle that are liens
     prior to or equal or coordinate with, the security interest in the Financed
     Vehicle granted by such Receivable;

          (13) with respect to which no default, breach, violation or event
     permitting acceleration thereof has occurred, and none of the Purchaser,
     the Servicer or any Seller has waived any of the foregoing;

          (14) at the time of the origination of which the related Financed
     Vehicle was covered by a comprehensive and collision insurance policy (i)
     in an amount at least equal to the lesser of (a) its maximum insurable
     value and (b) the Amount Financed, (ii) naming AFS or ACC, as applicable,
     as loss payee and (iii) insuring against loss and damage due to fire,
     theft, transportation, collision and other risks generally covered by
     comprehensive and collision coverage and with respect to which the Obligor
     is required to maintain physical loss and damage insurance, naming AFS or
     ACC and its successors and assigns as an additional insured party, and such
     Receivable permits the holder thereof to obtain Force-Placed Insurance at
     the expense of the Obligor if the Obligor fails to do so unless otherwise
     prohibited by the law of the state in which the related contract was
     entered into;

                                     S-A-3

 
          (15) with respect to which, (i) immediately prior to the sale thereof
     to the Purchaser, the applicable Seller had, and has conveyed to the
     Purchaser, good and marketable title free and clear of all liens,
     encumbrances, security interests and rights of others, and (ii) the sale
     and assignment thereof to the Purchaser has been perfected under the UCC;

          (16) with respect to each of which a Receivable File is in the
     possession of the Custodian and such Receivable File contains (i) the fully
     executed original of such Receivable, (ii) a certificate of insurance, an
     application form for insurance signed by the related Obligor, or a signed
     representation letter from the Obligor named in such Receivable pursuant to
     which such Obligor has agreed to obtain physical damage insurance for the
     related Financed Vehicle, or copies thereof, or a documented verbal
     confirmation by an insurance agent for such Obligor of a policy number for
     an insurance policy for the Financed Vehicle, (iii) the original Lien
     Certificate (indicating AFS or ACC as first lienholder) or application
     therefor or a letter from the applicable Dealer agreeing unconditionally to
     repurchase the related Receivable if the certificate of title is not
     received by the Servicer within 180 days (provided that the Lien
                                               --------
     Certificate is delivered to the Custodian within 180 days), and (iv) a
     credit application or file of credit information regarding the Obligor, or
     a copy thereof; each of such documents (if any) which is required to be
     signed by the Obligor has been signed by the Obligor in the appropriate
     spaces; and all blanks on any form have been properly filled in and each
     form has otherwise been correctly prepared;

          (17) which was not originated in, or is subject to the laws of, any
     jurisdiction the laws of which would make unlawful, void or voidable the
     sale, pledge, transfer and assignment of such Receivable under this
     Agreement and with respect to which a Seller has not entered into any
     agreement with any account debtor that prohibits, restricts or conditions
     the assignment of any portion of such Receivable;

          (18) as to which all filings (including, without limitation, UCC
     filings but subject to clause (p) above in the case of the applicable Lien
                            ----------
     Certificate) required to be made by any Person and actions required to be
     taken or performed by any Person in any jurisdiction to give the Collateral
     Agent, on behalf of the Secured Parties, a first priority perfected Lien on
     such Receivable and the proceeds thereof and the other Collateral related
     thereto have been made, taken or performed;

          (19) of which there is only one original executed copy;

          (20) which constitutes chattel paper within the meaning of the UCC;

          (21) as to which no selection procedures adverse to the Investors have
     been utilized in selecting such Receivable from all other similar
     Receivables owned or originated by AFS and its Affiliates;

                                     S-A-4

 
          (22) with respect to which, by the related Advance Date and on each
     relevant date thereafter, AFS or ACC or, to the extent it maintains such
     records, AFC (as the case may be) will have caused the portions of its
     servicing and other records relating to such Receivable to be clearly and
     unambiguously marked to show that such Receivable constitutes part of the
     Collateral and is subject to the Lien of the Collateral Agent on behalf of
     the Secured Parties;

          (23) which is not assumable by another Person in a manner which would
     release the Obligor thereof from such Obligor's obligations to the
     Purchaser with respect to such Receivable;

          (24) with respect to which the related Financed Vehicle had not been
     repossessed;

          (25) with respect to which the following is true:

                    The Lien Certificate for the related Financed Vehicle shows,
     or, if a new or replacement Lien Certificate is being applied for with
     respect to such Financed Vehicle, the Lien Certificate will be received
     within 180 days of the related Receivables Transfer Date and will show, AFS
     or ACC, as the case may be, named as the original secured party under such
     Receivable and, accordingly, AFS or ACC, as the case may be, will be the
     holder of a first priority security interest in such Financed Vehicle. With
     respect to each Receivable for which the Lien Certificate has not yet been
     returned from the Registrar of Titles, AFS or ACC, as the case may be, has
     received written evidence from the related Dealer or the Obligor that such
     Lien Certificate showing such Seller as first lienholder has been applied
     for. If the Receivable was originated in a state in which a filing or
     recording is required of the secured party to perfect a security interest
     in motor vehicles, such filings or recordings have been duly made to show
     AFS or ACC, as the case may be, named as the original secured party under
     the related Receivable;


          (26) which is not a Defaulted Receivable;

          (27) which is not a Delinquent Receivable;

          (28) which is not secured by vehicles which are financed
     repossessions; and

          (29) which was originated in the United States of America and, at the
     time of origination, materially conformed to all requirements of the
     Servicing Procedures and Credit Manual applicable to such Receivable.

                                     S-A-5

 
          For purposes of this Agreement (including the computation from time to
time of the Borrowing Base), the eligibility of Receivables will be determined
from time to time, such that a Receivable that was an Eligible Receivable at one
time but that subsequently fails to meet all applicable eligibility requirements
will no longer be an Eligible Receivable (unless and until it again meets all
applicable eligibility requirements).

                                                                       Exhibit A
