      SALE AND SERVICING AGREEMENT, dated as of November 1, 2006 (as from time
to time amended, supplemented or otherwise modified and in effect, this
"Agreement"), among USAA AUTO OWNER TRUST 2006-4 (the "Issuer"), a Delaware
statutory trust, USAA ACCEPTANCE, LLC, a Delaware limited liability company (the
"Depositor") and USAA FEDERAL SAVINGS BANK, a federally chartered savings
association, as seller of the Receivables to the Depositor (in such capacity,
the "Seller") and servicer (in such capacity, the "Servicer").

      WHEREAS, the Issuer desires to purchase a portfolio of receivables and
related property consisting of motor vehicle installment loan contracts
originated by the Seller in the ordinary course of its business;

      WHEREAS, the Seller is concurrently selling such portfolio of receivables
and related property to the Depositor pursuant to the Receivables Purchase
Agreement, and the Depositor is willing to sell such portfolio of receivables
and related property to the Issuer; and

      WHEREAS, the Servicer is willing to service such receivables on behalf of
the Issuer.

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto, intending to be
legally bound, agree as follows:

                                    ARTICLE I

                              DEFINITIONS AND USAGE

      Except as otherwise specified herein or as the context may otherwise
require, capitalized terms used but not otherwise defined herein are defined in
Appendix A hereto, which also contains rules as to usage that shall be
applicable herein.

                                   ARTICLE II

                                 TRUST PROPERTY

      SECTION 2.1 Conveyance of Trust Property; Intent of the Parties. In
consideration of the Issuer's delivery to, or upon the order of, the Depositor
of the Notes and the Certificates, the Depositor does hereby irrevocably sell,
transfer, assign and otherwise convey to the Issuer (i) without recourse
(subject to the obligations herein) all right, title and interest of the
Depositor, whether now owned or hereafter acquired, in and to the Trust Property
and (ii) funds in the amount of the Reserve Initial Deposit. The sale, transfer,
assignment and conveyance made hereunder shall not constitute and is not
intended to result in an assumption by the Issuer of any obligation of the
Depositor to the Obligors or any other Person in connection with the Receivables
and the other Trust Property or any agreement, document or instrument related
thereto. The Depositor and the Issuer intend that the sale, transfer, assignment
and conveyance of the Trust Property pursuant to this Section 2.1 shall be a
sale, and not a secured borrowing, for accounting purposes.

<PAGE>

      SECTION 2.2 Representations and Warranties of the Depositor regarding the
Receivables. The Depositor makes the following representations and warranties
with respect to the Receivables, on which the Issuer relies in purchasing the
Receivables and pledging the same to the Indenture Trustee. Such representations
and warranties speak as of the execution and delivery of this Agreement and as
of the Transfer Date, but shall survive the sale, transfer and assignment of the
Receivables by the Depositor to the Issuer and the pledge of the Receivables by
the Issuer to the Indenture Trustee pursuant to the Indenture.

      (i)   Schedule of Receivables. The information set forth in Schedule A to
            this Agreement with respect to each Receivable is true and correct
            in all material respects, and no selection procedures adverse to the
            Securityholders have been used in selecting the Receivables from all
            receivables owned by the Seller which meet the selection criteria
            specified herein.

      (ii)  No Sale or Transfer. No Receivable has been sold, transferred,
            assigned or pledged by the Depositor to any Person other than the
            Issuer.

      (iii) Good Title. Immediately prior to the transfer and assignment of the
            Receivables to the Issuer herein contemplated, the Depositor had
            good and marketable title to each Receivable free and clear of all
            Liens and rights of others; and, immediately upon the transfer
            thereof, the Issuer, has either (i) good and marketable title to
            each Receivable, free and clear of all of all Liens and rights of
            others, and the transfer has been perfected under applicable law or
            (ii) a first priority perfected security interest in each
            Receivable.

      (iv)  Receivable Files. The Receivable Files shall be kept at one or more
            of the locations specified in Schedule B-1 hereto; provided, that
            the Lien Certificates shall be kept at one or more of the locations
            specified in Schedule B-2 hereto.

      (v)   Characteristics of Receivables. Each Receivable (a) has been
            originated for the retail financing of a Financed Vehicle by an
            Obligor located in one of the States of the United States or the
            District of Columbia; (b) 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; and (c) provides for fully amortizing level
            scheduled monthly or semi-monthly payments (provided that the
            payment in the last month in the life of the Receivable may be
            different from the level scheduled payment) and for accrual of
            interest at a fixed rate according to the simple interest method.

      (vi)  Compliance with Law. Each Receivable and each sale of the related
            Financed Vehicle complied at the time it was originated or made, and
            complies on and after the Cut-off 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 Federal Trade Commission Act, the
            Magnuson-Moss Warranty Act, Federal Reserve Board Regulations B and
            Z, state adaptations of the National Consumer Act and of the Uniform
            Consumer Credit Code, and any

                                       2
<PAGE>

            other consumer credit, equal opportunity, and disclosure laws
            applicable to such Receivable and sale.

      (vii) Binding Obligation. Each Receivable constitutes the legal, valid,
            and binding payment obligation in writing of the Obligor,
            enforceable by the holder thereof in all material respects in
            accordance with its terms, subject, as to enforcement, to applicable
            bankruptcy, insolvency, reorganization, liquidation and other
            similar laws and equitable principles relating to or affecting the
            enforcement of creditors' rights.

     (viii) No Government Obligor. No Receivable is due from the United States
            of America or any state or from any agency, department,
            instrumentality or political subdivision of the United States of
            America or any state or local municipality and no Receivable is due
            from a business except to the extent that such receivable has a
            personal guaranty.

      (ix)  Security Interest in Financed Vehicle. Immediately prior to the sale
            and assignment thereof to the Issuer as herein contemplated, each
            Receivable was secured by a validly perfected first priority
            security interest in the Financed Vehicle in favor of the Seller as
            secured party or all necessary and appropriate action with respect
            to such Receivable had been taken to perfect a first priority
            security interest in the related Financed Vehicle in favor of the
            Seller as secured party, which security interest is assignable and
            has been so assigned by the Seller to the Depositor and by the
            Depositor to the Issuer.

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

      (xi)  No Waiver. No provision of a Receivable has been waived in such a
            manner that such Receivable fails either to meet all of the
            representations and warranties made by the Depositor herein with
            respect thereto pursuant to this Section 2.2.

      (xii) No Amendments. No Receivable has been amended except pursuant to
            instruments included in the Receivable Files and no such amendment
            has caused such Receivable either to fail to meet all of the
            representations and warranties made by the Depositor herein with
            respect thereto pursuant to this Section 2.2.

     (xiii) No Defenses. As of the Cut-off Date, there are no rights of
            rescission, setoff, counterclaim, or defense, and the Depositor has
            no knowledge of the same being asserted or threatened, with respect
            to any Receivable.

      (xiv) No Liens. As of the Cut-off Date, the Depositor has no knowledge of
            any Liens, claims that have been filed, including Liens for work,
            labor, materials or unpaid taxes relating to a Financed Vehicle,
            that would be Liens prior to, or equal or coordinate with, the Lien
            granted by the Receivable.

                                       3
<PAGE>

      (xv)  No Default. Except for payment defaults continuing for a period of
            not more than thirty (30) days as of the Cut-off Date, the Depositor
            has no knowledge that a default, breach, violation, or event
            permitting acceleration under the terms of any Receivable exists;
            the Depositor has no knowledge that a continuing condition that with
            notice or lapse of time would constitute a default, breach,
            violation, or event permitting acceleration under the terms of any
            Receivable exists; and the Depositor has not waived any of the
            foregoing.

      (xvi) Insurance. Each Receivable requires that the Obligor thereunder
            obtain comprehensive and collision insurance covering the Financed
            Vehicle.

     (xvii) Lawful Assignment. No Receivable has been originated in, or is
            subject to the laws of, any jurisdiction under which the sale,
            transfer, and assignment of such Receivable under the Agreement is
            unlawful, void or voidable.

    (xviii) All Filings Made. No filings (other than UCC filings which have
            been made) or other actions are necessary in any jurisdiction to
            give the Issuer a first priority perfected security interest in the
            Receivables and to give the Indenture Trustee a first priority
            perfected security interest in the Receivables.

      (xix) One Original. With respect to any Receivable for which an original
            executed copy exists, there is no more than one original executed
            copy of such Receivable which does not have any marks or notations
            indicating that it has been pledged, assigned or otherwise conveyed
            to any Person other than the Seller and which, immediately prior to
            the delivery thereof to the Servicer, as custodian for the Indenture
            Trustee, was in the possession of the Seller.

      (xx)  Security. Each Receivable is secured by a new or used automobile or
            light-duty truck.

      (xxi) Maturity of Receivables. Each Receivable has a remaining maturity,
            as of the Cut-off Date, of not less than 8 months and not more than
            72 months and an original maturity of not less than 9 months and not
            more than 72 months. No Receivable has a scheduled maturity later
            than December 15, 2012.

     (xxii) Annual Percentage Rate. Each Receivable is a fully-amortizing
            simple interest contract which bears interest at a fixed rate per
            annum and which provides for level scheduled monthly or semi-monthly
            payments (except for the last payment, which may be minimally
            different from the level payments) over its respective remaining
            term, is not secured by any interest in real estate.

    (xxiii) No Repossessions. Each Receivable is secured by a Financed Vehicle
            that, as of the Cut-off Date, has not been repossessed without
            reinstatement of such Receivable.

                                       4
<PAGE>

     (xxiv) Obligor Not Subject to Bankruptcy Proceedings. Each Receivable has
            been entered into by an Obligor who has not been identified on the
            computer files of the Seller as being a debtor in any bankruptcy
            proceeding as of the Cut-off Date.

      (xxv) No Overdue Payments. No Receivable has any payment that is more than
            thirty (30) days past due as of the Cut-off Date.

     (xxvi) Tangible Chattel Paper. The Receivables constitute "tangible
            chattel paper" within the meaning of UCC Section 9-102.

    (xxvii) Remaining Principal Balance. Each Receivable had a remaining
            principal balance, as of the Cut-off Date, of at least $800.00.

   (xxviii) Filing Statement Language. The financing statements referenced in
            paragraph (xviii) above, will contain a statement to the following
            effect "A purchase of or security interest in any collateral
            described in this financing statement will violate the rights of the
            Secured Party".

      SECTION 2.3 Repurchase upon Breach. Each of the Depositor, the Servicer,
the Issuer and the Owner Trustee shall inform the other parties to this
Agreement promptly, in writing, upon the discovery by it of any breach of the
Depositor's representations and warranties pursuant to Section 2.2. Unless the
breach shall have been cured by the last day of the second Collection Period
following written notice to the Indenture Trustee of such breach, the Indenture
Trustee shall enforce the obligation of the Depositor under this Section 2.3 to
repurchase any Receivable, the Issuer's interest in which is materially and
adversely affected by the breach as of such last day (or, at the Depositor's
option, the last day of the first Collection Period following the discovery). In
consideration of the purchase of the Receivable, the Depositor shall remit the
Purchase Amount (less any Liquidation Proceeds deposited, or to be deposited, in
the Collection Account with respect to such Receivable pursuant to Section 3.3),
in the manner specified in Section 4.5. The sole remedy of the Issuer, the Owner
Trustee, the Indenture Trustee, the Noteholders or the Certificateholders with
respect to a breach of the Depositor's representations and warranties pursuant
to Section 2.2 shall be to require the Depositor to repurchase such Receivables
pursuant to this Section 2.3. The obligation of the Depositor to repurchase
under this Section 2.3 shall not be solely dependent upon the actual knowledge
of the Depositor of any breached representation or warranty. Neither the Owner
Trustee nor the Indenture Trustee shall have any duty to conduct an affirmative
investigation as to the occurrence of any condition requiring the repurchase of
any Receivable pursuant to this Section 2.3 or the eligibility of any Receivable
for purposes of this Agreement. Notwithstanding anything herein to the contrary,
the Depositor shall only be obligated to pay such Purchase Amount and repurchase
the related Receivable to the extent it receives the Purchase Amount from the
Seller pursuant to Section 7.02 of the Receivables Purchase Agreement.

      SECTION 2.4 Custody of Receivable Files. To assure uniform quality in
servicing the Receivables and to reduce administrative costs, the Issuer, upon
the execution and delivery of this Agreement, hereby revocably appoints the
Servicer, and the Servicer hereby accepts such appointment, to act as the agent
of the Issuer and the Indenture Trustee as custodian of the

                                       5
<PAGE>

following documents or instruments, which are hereby constructively delivered to
the Indenture Trustee, as pledgee of the Issuer pursuant to the Indenture, with
respect to each Receivable:

            (i) The original executed Receivable or, if no such original exists,
      a copy thereof.

            (ii) The original credit application fully executed by the Obligor
      or a photocopy thereof or a record thereof on a computer file, diskette or
      on microfiche.

            (iii) The notice of recorded Lien or such documents that the
      Servicer or the Depositor shall keep on file, in accordance with its
      customary procedures, evidencing the first priority perfected security
      interest of the Seller in the Financed Vehicle.

            (iv) Any and all other documents (including any computer file,
      diskette or microfiche) that the Servicer or the Seller shall keep on
      file, in accordance with its customary procedures, relating to a
      Receivable, an Obligor (to the extent relating to a Receivable), or a
      Financed Vehicle.

      The Servicer acknowledges that it holds the documents and instruments
relating to the Receivables for the benefit of the Issuer and the Indenture
Trustee. The Issuer and the Indenture Trustee shall have no responsibility to
monitor the Servicer's performance as custodian and shall have no liability in
connection with the Servicer's performance of such duties hereunder.

      SECTION 2.5 Duties of Servicer as Custodian.

      (a)   Safekeeping. The Servicer shall hold the Receivable Files for the
benefit of the Issuer and the Indenture Trustee and shall maintain such accurate
and complete accounts, records and computer systems pertaining to each
Receivable File as shall enable the Servicer and the Issuer to comply with the
terms and conditions of this Agreement, and the Indenture Trustee to comply with
the terms and conditions of the Indenture. In performing its duties as
custodian, the Servicer shall act with reasonable care, using that degree of
skill and attention that the Servicer exercises with respect to the receivable
files relating to all comparable automotive receivables that the Servicer
services for itself or others. The Servicer shall conduct, or cause to be
conducted, periodic audits of the Receivable Files held by it under this
Agreement and of the related accounts, records and computer systems, in such a
manner as shall enable the Issuer or the Indenture Trustee to identify all
Receivables Files and such related accounts, records and computer systems and
verify the accuracy of the Servicer's record keeping. The Servicer shall
promptly report to the Issuer and the Indenture Trustee any failure on its part
to hold the Receivable Files and maintain its accounts, records, and computer
systems as herein provided and shall promptly take appropriate action to remedy
any such failure. Nothing herein shall be deemed to require an initial review or
any periodic review by the Issuer, the Owner Trustee or the Indenture Trustee of
the Receivable Files.

      (b)   Maintenance of and Access to Records. The Servicer shall maintain
each Receivable File at its offices specified in Schedule B-1 to this Agreement
provided, that all Lien Certificates will be maintained at the location
specified in Schedule B-2, or at such other office as shall be specified to the
Issuer and the Indenture Trustee by 30 days' prior written notice. The Servicer
shall make available to the Issuer and the Indenture Trustee or their duly
authorized

                                       6
<PAGE>

representatives, attorneys, or auditors, the Receivable Files and the
related accounts, records and computer systems maintained by the Servicer during
normal business hours as the Issuer or the Indenture Trustee shall reasonably
request, which does not unreasonably interfere with the Servicer's normal
operations.

      (c)  Release of Documents. Upon written instructions from the Indenture
Trustee, the Servicer shall release or cause to be released any document in the
Receivable Files to the Indenture Trustee, the Indenture Trustee's agent or the
Indenture Trustee's designee, as the case may be, at such place or places as the
Indenture Trustee may reasonably designate, as soon as is reasonably
practicable, to the extent it does not unreasonably interfere with the
Servicer's normal operations. The Servicer shall not be responsible for any loss
occasioned by the failure of the Indenture Trustee or its agent or designee to
return any document or any delay in doing so.

      SECTION 2.6 Instructions; Authority to Act. All instructions from the
Indenture Trustee shall be in writing and signed by an Authorized Officer of the
Indenture Trustee, and the Servicer shall be deemed to have received proper
instructions with respect to the Receivable Files upon its receipt of such
written instructions.

      SECTION 2.7 Custodian's Indemnification. The Servicer, as custodian, shall
indemnify the Issuer, the Owner Trustee and the Indenture Trustee for any and
all liabilities, obligations, losses, compensatory damages, payments, costs, or
expenses of any kind whatsoever that may be imposed on, incurred, or asserted
against the Issuer, the Owner Trustee or the Indenture Trustee as the result of
any improper act or omission in any way relating to the maintenance and custody
by the Servicer as custodian of the Receivable Files; provided, however, that
the Servicer shall not be liable (i) to the Issuer for any portion of any such
amount resulting from the willful misfeasance, bad faith, or negligence of the
Indenture Trustee, the Owner Trustee or the Issuer, (ii) to the Owner Trustee
for any portion of any such amount resulting from the willful misfeasance, bad
faith, or negligence of the Indenture Trustee, the Owner Trustee or the Issuer
and (iii) to the Indenture Trustee for any portion of any such amount resulting
from the willful misfeasance, bad faith, or negligence of the Indenture Trustee,
the Owner Trustee or the Issuer.

      SECTION 2.8 Effective Period and Termination. The Servicer's appointment
as custodian shall become effective as of the Cut-off Date and shall continue in
full force and effect until terminated pursuant to this Section 2.8. If the Bank
shall resign as Servicer in accordance with the provisions of this Agreement or
if all of the rights and obligations of the Servicer shall have been terminated
under Section 7.1, the appointment of the Servicer as custodian hereunder may be
terminated by the Indenture Trustee, or by the holders of Notes evidencing not
less than a majority of the principal amount of the Controlling Class
Outstanding (or if no Notes are Outstanding, by holders of Certificates
evidencing not less than a majority of the Percentage Interests evidenced by the
Certificates), in the same manner as the Indenture Trustee or such
Securityholders may terminate the rights and obligations of the Servicer under
Section 7.1. As soon as practicable after any termination of such appointment,
the Servicer shall deliver to the Indenture Trustee or the Indenture Trustee's
agent the Receivable Files and the related accounts and records maintained by
the Servicer at such place or places as the Indenture Trustee may reasonably
designate.

         ADMINISTRATION AND SERVICING OF RECEIVABLES AND TRUST PROPERTY

      SECTION 3.1 Duties of Servicer. The Servicer shall manage, service,
administer and make collections on the Receivables with reasonable care, using
that degree of skill and attention that the Servicer exercises with respect to
all comparable new or used automobile and light-duty truck receivables that it
services for itself. The Servicer's duties shall include collection and posting
of all payments, responding to inquiries of Obligors on such Receivables,
investigating delinquencies, sending payment coupons to Obligors, reporting tax
information to Obligors, accounting for collections, furnishing monthly and
annual statements to the Owner Trustee and the Indenture Trustee with respect to
distributions, making Advances pursuant to Section 4.4, preparing (or causing to
be prepared) the tax returns of the Trust in accordance with Section 5.6 of the
Trust Agreement and, if requested to do so, providing the certifications
required, pursuant to Section 5.1(b) hereof. The Servicer shall follow its
customary standards, policies and procedures in performing its duties as
Servicer. Without limiting the generality of the foregoing, the Servicer is
hereby authorized and empowered to execute and deliver, on behalf of itself, the
Issuer, the Owner Trustee, the Indenture Trustee, the Noteholders, the
Certificateholders, or any of them, any and all instruments of satisfaction or
cancellation, or partial or full release or discharge, and all other comparable
instruments, with respect to such Receivables or to the Financed Vehicles
securing such Receivables. If the Servicer shall commence a legal proceeding to
enforce a Receivable, the Issuer (in the case of a Receivable other than a
Purchased Receivable) shall thereupon be deemed to have automatically assigned,
solely for the purpose of collection, such Receivable to the Servicer. If in any
enforcement suit or legal proceeding it shall be held that the Servicer may not
enforce a Receivable on the ground that it shall not be a real party in interest
or a holder entitled to enforce the Receivable, the Issuer shall, at the
Servicer's expense and direction, take steps to enforce the Receivable,
including bringing suit in its name or the names of the Indenture Trustee, the
Noteholders, the Certificateholders, or any of them. The Issuer shall furnish
the Servicer with any powers of attorney and other documents reasonably
necessary or appropriate to enable the Servicer to carry out its servicing and
administrative duties hereunder.

      SECTION 3.2 Collection of Receivable Payments. The Servicer shall make
reasonable efforts to collect all payments called for under the terms and
provisions of the Receivables as and when the same shall become due and shall
follow such collection procedures as it follows with respect to all comparable
new or used automobile and light-duty truck receivables that it services for
itself. The Servicer shall not change the amount of or reschedule the due date
of any scheduled payment of a Receivable to a date more than 30 days from the
original due date of such scheduled payment, change the annual percentage rate
of or extend any Receivable or change any material term of a Receivable, except
as provided by the terms of the Receivable or of this Agreement or as required
by law or court order; provided, however, that the Servicer may extend any
Receivable that is in default or with respect to which default is reasonably
foreseeable and that would be acceptable to the Servicer with respect to
comparable new or used automobile and light-duty truck receivables that it
services for itself if (a) the amount on deposit in the Reserve Account is
greater than zero at the time of the extension, (b) the total credit-related
extensions granted on the Receivable will not exceed four months in

                                       8
<PAGE>

the aggregate, (c) the total number of credit-related extensions granted on the
Receivable will not exceed two, and (d) the maturity of such Receivable will not
be extended beyond December 2012. If, as a result of inadvertently rescheduling
or extending payments, such rescheduling or extension breaches any of the terms
of the proviso to the preceding sentence, then the Servicer shall be obligated
to purchase such Receivable pursuant to Section 3.7. For the purpose of such
purchases pursuant to Section 3.7, notice shall be deemed to have been received
by the Servicer at such time as shall make purchase mandatory as of the last day
of the Collection Period during which the discovery of such breach occurred.

      Notwithstanding anything to the contrary herein, the Servicer may
implement programs that grant payment extensions in respect of receivables that
are not delinquent. Any such program shall be implemented with the approval of
the senior officer's credit committee of the Servicer in accordance with the
Servicer's general lending and policy guidelines. Any such payment extension may
extend the maturity of the applicable receivable beyond its original term to
maturity. Notwithstanding anything to the contrary herein, the Servicer may also
reduce the interest rate on Receivables affected by the application of the
Servicemembers Civil Relief Act to a rate that is lower than the maximum rate
prescribed by the Servicemembers Civil Relief Act and may readjust the payment
schedule for any Receivable that is affected by the application of the
Servicemembers Civil Relief Act until the maturity of the receivable.

      The Servicer may at any time perform specific duties as servicer or
custodian under this Agreement through subcontractors; provided, however, that
no such delegation or subcontracting shall relieve the Servicer of its
responsibilities with respect to such duties as to which the Servicer shall
remain primarily responsible with respect thereto. All amounts payable to any
subcontractor shall be paid by the Servicer and shall not be obligations of the
Indenture Trustee, the Owner Trustee or the Issuer or paid from the Indenture
Trust Estate. References in this Agreement to actions taken or to be taken by
the Servicer include actions taken or to be taken by a subcontractor on behalf
of the Servicer.

      SECTION 3.3 Realization Upon Receivables. On behalf of the Issuer, the
Servicer shall use reasonable efforts, consistent with its customary standards,
policies and procedures, to repossess or otherwise convert the ownership of the
Financed Vehicle securing any Receivable as to which the Servicer shall have
determined to be a Defaulted Receivable or otherwise (and shall specify any such
Defaulted Receivable to the Indenture Trustee no later than the Determination
Date following the Collection Period in which the Servicer shall have made such
determination). The Servicer shall follow such customary standards, policies and
procedures as it shall deem necessary or advisable in its servicing of
comparable receivables, which may include selling the Financed Vehicle at public
or private sale. The Servicer shall be entitled to recover from proceeds all
reasonable expenses incurred by it in the course of converting the Financed
Vehicle into cash proceeds. The Liquidation Proceeds (net of such expenses)
realized in connection with any such action with respect to a Receivable shall
be deposited by the Servicer in the Collection Account in the manner specified
in Section 4.2 and shall be applied to reduce (or to satisfy, as the case may
be) the Purchase Amount of the Receivable, if such Receivable is to be
repurchased by the Depositor pursuant to Section 2.3, or is to be purchased by
the Servicer pursuant to Section 3.7. The foregoing shall be subject to the
provision that, in any case in which the Financed Vehicle shall have suffered
damage, the Servicer shall not be required to

                                       9
<PAGE>

expend funds in connection with the repair or the repossession of such Financed
Vehicle unless it shall determine in its discretion that such repair and/or
repossession will increase the Liquidation Proceeds by an amount greater than
the amount of such expenses.

      SECTION 3.4 Allocations of Collections. If an Obligor is obligated under
one or more Receivables and also under one or more other assets owned by the
Bank or assigned by the Bank to third parties, then any payment on any such
asset received from or on behalf of such Obligor shall, if identified as being
made with respect to a particular item or asset, be applied to such item, and
otherwise shall be allocated by the Bank in accordance with its customary
standards, policies and procedures.

      SECTION 3.5 Maintenance of Security Interests in Financed Vehicles. The
Servicer shall, in accordance with its customary procedures, take such steps as
are necessary to maintain perfection of the security interest created by each
Receivable in the related Financed Vehicle. The Issuer hereby authorizes the
Servicer to take such steps as are necessary to re-perfect such security
interest on behalf of the Issuer and the Indenture Trustee in the event of the
relocation of a Financed Vehicle or for any other reason, in either case, when
the Servicer has knowledge of the need for such re-perfection. In the event that
the assignment of a Receivable to the Issuer is insufficient, without a notation
on the related Financed Vehicle's certificate of title, or without fulfilling
any additional administrative requirements under the laws of the state in which
the Financed Vehicle is located, to transfer to the Issuer a perfected security
interest in the related Financed Vehicle, the Servicer hereby agrees that the
Servicer's listing as the secured party on the certificate of title is deemed to
be in its capacity as agent of the Issuer and the Indenture Trustee and further
agrees to hold such certificate of title as the agent and custodian of the
Issuer and the Indenture Trustee; provided that the Servicer shall not, nor
shall the Issuer or the Indenture Trustee have the right to require that the
Servicer, make any such notation on the related Financed Vehicles' certificate
of title or fulfill any such additional administrative requirement of the laws
of the state in which a Financed Vehicle is located.

      SECTION 3.6 Covenants of Servicer. The Servicer shall not (i) release the
Financed Vehicle securing each such Receivable from the security interest
granted by such Receivable in whole or in part except in the event of payment in
full by or on behalf of the Obligor thereunder, (ii) impair the rights of the
Trust or the Indenture Trustee in the Receivables, or (iii) increase the number
of payments under a Receivable, increase the Amount Financed under a Receivable
or extend or forgive payments on a Receivable, except as provided in Section
3.2. In the event that at the end of the scheduled term of any Receivable, the
outstanding principal amount thereof is such that the final payment to be made
by the related Obligor is larger than the regularly scheduled payment of
principal and interest made by such Obligor, the Servicer may permit such
Obligor to pay such remaining principal amount in more than one payment of
principal and interest; provided that the last such payment shall be due on or
prior to the Collection Period immediately preceding the Class B Final Scheduled
Payment Date.

      SECTION 3.7 Purchase of Receivables Upon Breach. (a) The Servicer, the
Depositor or the Owner Trustee, as the case may be, promptly shall inform the
other parties to this Agreement, in writing, upon the discovery of any breach
pursuant to Section 3.2, 3.5 or 3.6. Unless the breach shall have been cured by
the last day of the second Collection Period following such discovery (or, at
the Servicer's election, the last day of the first following Collection Period),

                                       10
<PAGE>

the Servicer shall purchase any Receivable materially and adversely affected by
such breach as determined by the Indenture Trustee (which shall include any
Receivable as to which a breach of Section 3.6 has occurred) at the Purchase
Amount (less any Liquidation Proceeds deposited, or to be deposited, in the
Collection Account with respect to such Receivable pursuant to Section 3.3). In
consideration of the purchase of such Receivable, the Servicer shall remit the
Purchase Amount in the manner specified in Section 4.5. For purposes of this
Section 3.7, the Purchase Amount shall consist in part of a release by the
Servicer of all rights of reimbursement with respect to Outstanding Advances on
the Receivable. The sole remedy of the Issuer, the Owner Trustee, the Indenture
Trustee, the Noteholders or the Certificateholders with respect to a breach
pursuant to Section 3.2, 3.5 or 3.6 shall be to require the Servicer to purchase
Receivables pursuant to this Section 3.7.

      (b)   With respect to all Receivables purchased pursuant to this Section
3.7, the Issuer shall assign to the Servicer or the Depositor, as applicable,
without recourse, representation or warranty, all of the Issuer's right, title
and interest in and to such Receivables and all security and documents relating
thereto.

      SECTION 3.8 Servicer Fees. The Servicer shall be entitled to any interest
earned on the amounts deposited in the Collection Account during each Collection
Period plus all late fees, prepayment charges and other administrative fees and
expenses or similar charges, if any, allowed by applicable law and the terms of
the Receivables during each Collection Period (the "Supplemental Servicing
Fee"). The Servicer also shall be entitled to the Servicing Fee, as provided
herein.

      SECTION 3.9 Servicer's Certificate. On or prior to the Determination Date
for each Payment Date, the Servicer shall deliver to the Depositor, the Owner
Trustee, each Note Paying Agent and Certificate Paying Agent, the Indenture
Trustee and the Seller, with a copy to the Rating Agencies, a Servicer's
Certificate containing all information (including all specific dollar amounts)
necessary to make the transfers and distributions pursuant to Sections 4.3, 4.4,
4.5, 4.6 and 4.7 hereof, and Section 8.2 of the Indenture for the Collection
Period preceding the date of such Servicer's Certificate, together with the
written statements to be furnished by the Owner Trustee to Certificateholders
pursuant to Section 4.9 hereof and by the Indenture Trustee to the Noteholders
pursuant to Section 4.9 hereof and Section 6.6 of the Indenture. Receivables
purchased or to be purchased by the Servicer or the Depositor shall be
identified by the Servicer by the Seller's account number with respect to such
Receivable (as specified in the Schedule of Receivables).

      SECTION 3.10 Annual Statement as to Compliance; Item 1122 Servicing
Criteria Assessment; Notice of Event of Servicing Termination. (a) The Servicer
shall deliver to the Owner Trustee, the Indenture Trustee and each Rating Agency
on or before March 31 of each year beginning March 31, 2007,

      (i) an Officer's Certificate, with respect to the preceding 12-month
period (or such shorter period in the case of the first such certificate),
stating that (x) a review of the activities of the Servicer during the preceding
12-month period (or such shorter period in the case of the first

                                       11
<PAGE>

such certificate) and of its performance under this Agreement has been made
under such officer's supervision and (y) to the best of such officer's
knowledge, based on such review, the Servicer has fulfilled all its obligations
in all material respects under this Agreement throughout such period, or, if
there has been a failure to fulfill any such obligation in any material respect,
specifying each such failure known to such officer and the nature and status
thereof, and

      (ii) the servicing criteria assessment required to be filed in respect of
the Trust under the Exchange Act under Item 1122 of Regulation AB if periodic
reports under Section 15(d) of the Exchange Act, or any successor provision
thereto, were required to be filed in respect of the Trust. Such report shall be
signed by an authorized officer of the Servicer and shall at a minimum address
each of the Servicing Criteria specified on a certification substantially in the
form of Appendix C hereto delivered to the Depositor concurrently with the
execution of this Agreement. To the extent any of the Servicing Criteria are not
applicable to the Servicer, with respect to asset-backed securities transactions
taken as a whole involving the Servicer and that are backed by the same asset
type backing the Notes, such report shall include such a statement to that
effect. The Depositor and the Servicer, and each of their respective officers
and directors shall be entitled to rely on upon each such servicing criteria
assessment.

      A copy of such Officer's Certificate and the report referred to in Section
3.11 may be obtained by any Certificateholder by a request in writing to the
Owner Trustee, or by any Noteholder or Person certifying that it is a Note Owner
by a request in writing to the Indenture Trustee, in either case addressed to
the applicable Corporate Trust Office. Upon the telephone request of the Owner
Trustee, the Indenture Trustee shall promptly furnish the Owner Trustee a list
of Noteholders as of the date specified by the Owner Trustee.

      (b) The Servicer shall deliver to the Owner Trustee, the Indenture Trustee
and each Rating Agency promptly after having obtained knowledge thereof, but in
no event later than five (5) Business Days thereafter, written notice in an
Officer's Certificate of any event which with the giving of notice or lapse of
time, or both, would become an Event of Servicing Termination under Section 7.1.
The Seller shall deliver to the Owner Trustee, the Indenture Trustee and each
Rating Agency promptly after having obtained knowledge thereof, but in no event
later than five (5) Business Days thereafter, written notice in an Officer's
Certificate of any event which with the giving of notice or lapse of time, or
both, would become an Event of Servicing Termination under clause (a)(ii) of
Section 7.1.

      (c) The Servicer shall cause each Reporting Subcontractor to deliver to
the Depositor an assessment of compliance and accountant's attestation as and
when provided in paragraph (a)(ii) of this Section 3.10 and Section 3.11. The
Servicer shall execute (provided the Servicer is not an Affiliate of the
Depositor) (and shall cause each Reporting Subcontractor to execute) a reliance
certificate to enable the Certification Parties to rely upon each (i) annual
report on assessments of compliance with servicing criteria provided pursuant to
Section 3.10 and (ii) accountant's report provided pursuant to Section 3.10 and
shall include a certification that each such annual compliance statement or
report discloses any deficiencies or defaults described to the registered public
accountants of such Person to enable such accountants to render the certificates
provided for in Section 3.11.

                                       12
<PAGE>

      (d) In the event the Servicer, any Subservicer or Reporting Subcontractor
is terminated or resigns during the term of this Agreement, such Person shall
provide the documents and information pursuant to Section 3.10 and Section 3.11
with respect to the period of time it was subject to this Agreement or provided
services with respect to the Trust or the Receivables. Notwithstanding anything
to the contrary contained herein, if the Servicer has exercised commercially
reasonable efforts to obtain any assessment or attestation required hereunder
from a Reporting Subcontractor, the failure by the Reporting Subcontractor to
provide such attestation on or assessment shall not constitute a breach
hereunder by the Servicer.

      SECTION 3.11 Annual Independent Certified Public Accountant's Report. The
Servicer shall cause a firm of independent certified public accountants, who may
also render other services to the Servicer, the Seller or the Depositor, to
deliver to the Owner Trustee and the Indenture Trustee on or before March 31 of
each year beginning March 31, 2007 with respect to the prior calendar year (or
such shorter period in the case of the first such report) the attestation report
that would be required to be filed in respect of the Trust under the Exchange
Act if periodic reports under Section 15(d) of the Exchange Act, or any
successor provision thereto, were required to be filed in respect of the Trust.
Such attestation shall be in accordance with Rules 1-02(a)(3) and 2-02(g) of
Regulation S-X under the Securities Act and the Exchange Act, including, without
limitation that in the event that an overall opinion cannot be expressed, such
registered public accounting firm shall state in such report why it was unable
to express such an opinion.

      SECTION 3.12 Access to Certain Documentation and Information Regarding
Receivables. The Servicer shall provide to the Certificateholders, the Indenture
Trustee and the Noteholders access to the Receivable Files in such cases where
the Certificateholders, the Indenture Trustee or the Noteholders shall be
required by applicable statutes or regulations to review such documentation.
Access shall be afforded without charge, but only upon reasonable request and
during the normal business hours at the respective offices of the Servicer.
Nothing in this Section 3.12 shall affect the obligation of the Servicer to
observe any applicable law prohibiting disclosure of information regarding the
Obligors, and the failure of the Servicer to provide access to information as a
result of such obligation shall not constitute a breach of this Section 3.12.

      SECTION 3.13 Servicer Expenses. The Servicer shall be required to pay all
expenses incurred by it in connection with its activities hereunder, including
fees, expenses (including counsel fees and expenses) and disbursements of the
Owner Trustee and the Indenture Trustee, independent accountants, taxes imposed
on the Servicer and expenses incurred in connection with distributions and
reports to Noteholders and Certificateholders.

      SECTION 3.14 Insurance. The Servicer, in accordance with its customary
servicing procedures and underwriting standards, shall require that each Obligor
shall have obtained and shall maintain comprehensive and collision insurance
covering the related Financed Vehicle as of the execution of the Receivable. The
Servicer shall enforce its rights under the Receivables to require the Obligors
to maintain comprehensive and collision insurance, in accordance with the
Servicer's customary practices and procedures with respect to comparable new or
used automobile and light-duty truck receivables that it services for itself or
others.

                  DISTRIBUTIONS; RESERVE ACCOUNT; STATEMENTS TO
                       NOTEHOLDERS AND CERTIFICATEHOLDERS

      SECTION 4.1 Accounts. (a) The Servicer shall, prior to the Closing Date,
cause to be established and maintained an Eligible Deposit Account in the name
"The Bank of New York, as Indenture Trustee, as secured party from USAA Auto
Owner Trust 2006-4", initially at the corporate trust department of the
Indenture Trustee, which shall be designated as the "Collection Account". The
Collection Account shall be under the sole dominion and control of the Indenture
Trustee; provided, that the Servicer may make deposits to and direct the
Indenture Trustee in writing to make withdrawals from the Collection Account in
accordance with the terms of the Basic Documents. The Collection Account will be
established and maintained pursuant to an account agreement which specifies New
York law as the governing law. In addition, the Collection Account shall be
established and maintained at an institution which agrees in writing that for so
long as the Notes are outstanding it will comply with entitlement orders (as
defined in Article 8 of the UCC) originated by the Indenture Trustee without
further consent of the Issuer. All monies deposited from time to time in the
Collection Account shall be held by the Indenture Trustee as secured party for
the benefit of the Noteholders and, after payment in full of the Notes, as agent
of the Issuer and as part of the Trust Property. All deposits to and withdrawals
from the Collection Account shall be made only upon the terms and conditions of
the Basic Documents.

      If the Servicer is required to remit collections pursuant to the first
sentence of Section 4.2, all amounts held in the Collection Account shall, to
the extent permitted by applicable law, rules and regulations, be invested, as
directed in writing by the Servicer, by the bank or trust company then
maintaining the Collection Account in specified Permitted Investments that
mature not later than the Business Day immediately prior to the Payment Date for
the Collection Period to which such amounts relate (or in the case of the
Special Payment Date, the portion of such funds needed to make the final payment
on the Class A-1 Notes shall mature not later than the Business Day immediately
prior to the Special Payment Date) and such Permitted Investments shall be held
to maturity. All interest and other income (net of losses and investment
expenses) on funds on deposit in the Collection Account shall be withdrawn from
the Collection Account at the written direction of the Servicer and shall be
paid to the Servicer. The Indenture Trustee shall not be liable for investment
losses in Permitted Investments made in accordance with directions from the
Servicer. In the event that the Collection Account is no longer to be maintained
at the corporate trust department of the Indenture Trustee, the Servicer shall,
with the Indenture Trustee's or Issuer's assistance as necessary, cause an
Eligible Deposit Account to be established as the Collection Account within ten
(10) Business Days (or such longer period not to exceed thirty (30) calendar
days as to which each Rating Agency may consent) and give written notice of the
location and account number of such account to the Indenture Trustee.

      (b) The Servicer shall, prior to the Closing Date, cause to be established
 and maintained an Eligible Deposit Account in the name "The Bank of New York,

department of the Indenture Trustee, which shall be designated as the "Principal
Distribution Account". The Principal Distribution Account shall be under the
sole dominion and control of the Indenture Trustee; provided, that the Servicer
may make deposits to and direct the Indenture Trustee in writing to make
withdrawals from the Principal Distribution Account in accordance with the terms
of the Basic Documents. The Principal Distribution Account will be established
and maintained pursuant to an account agreement which specifies New York law as
the governing law. In addition, the Principal Distribution Account shall be
established and maintained at an institution which agrees in writing that for so
long as the Notes are outstanding it will comply with entitlement orders (as
defined in Article 8 of the UCC) originated by the Indenture Trustee without
further consent of the Issuer. All monies deposited from time to time in the
Principal Distribution Account shall be held by the Indenture Trustee as secured
party for the benefit of the Noteholders and, after payment in full of the
Notes, as agent of the Issuer and as part of the Trust Property. All deposits to
and withdrawals from the Principal Distribution Account shall be made only upon
the terms and conditions of the Basic Documents.

      (c) The Servicer shall, prior to the Closing Date, cause an Eligible
 Deposit Account to be established and maintained, in the name "USAA Auto Owner
 Trust 2006-4 Certificate Distribution Account", initially at the corporate
 trust department of the Owner Trustee, which shall be designated as the
 "Certificate Distribution Account". The Certificate Distribution Account shall
 be under the sole dominion and control of the Owner Trustee. All monies
 deposited from time to time in the Certificate Distribution Account pursuant to
 this Agreement and the Indenture shall be held by the Owner Trustee as part of
 the Trust Property and shall be applied as provided in the Basic Documents. In
 the event that the Certificate Distribution Account is no longer to be
 maintained at the corporate trust department of the Owner Trustee, the Servicer
 shall cause an Eligible Deposit Account to be established as the Certificate
 Distribution Account within ten (10) Business Days (or such longer period not
 to exceed thirty (30) calendar days as to which each Rating Agency may consent)
 and give written notice of the location and account number of such account to
 the Owner Trustee. The Certificate Distribution Account will be established and
 maintained pursuant to an account agreement which specifies New York law as the
 governing law.

      SECTION 4.2 Collections. The Servicer shall remit to the Collection
Account within two (2) Business Days of the receipt thereof (i) all payments by
or on behalf of the Obligors (but excluding Purchased Receivables) and (ii) all
Liquidation Proceeds, both as collected during the Collection Period; provided
that the Bank, so long as it is acting as the Servicer and no Event of Servicing
Termination has occurred and is continuing, may make remittances of collections
on a less frequent basis than that specified in the immediately preceding
sentence. It is understood that such less frequent remittances may be made only
on the specific terms and conditions set forth below in this Section 4.2 and
only for so long as such terms and conditions are fulfilled. Accordingly,
notwithstanding the provisions of the first sentence of this Section 4.2, the
Servicer shall remit collections received during a Collection Period to the
Collection Account in immediately available funds on the Business Day preceding
the related Payment Date (or in the case of the Special Payment Date, on the
Business Day preceding the Special Payment Date) but only for so long as the
Monthly Remittance Condition is satisfied. The Owner Trustee or the Indenture
Trustee shall not be deemed to have knowledge of any event or circumstance in
the definition of Monthly Remittance Condition that would require remittance by
the Servicer to the

                                       15
<PAGE>

Collection Account within two (2) Business Days of receipt as aforesaid unless
the Owner Trustee or the Indenture Trustee has received written notice of such
event or circumstance from the Seller or the Servicer in an Officer's
Certificate or from the holders of Notes evidencing not less than 25% of the
principal amount of the Notes Outstanding or from the Certificateholders of
Certificates evidencing not less than 25% of the Percentage Interests evidenced
by the Certificates or a Trustee Officer in the Corporate Trust Office with
knowledge hereof or familiarity herewith has actual knowledge of such event or
circumstance. For purposes of this Article IV the phrase "payments by or on
behalf of Obligors" shall mean payments made by Persons other than the Servicer
or by other means.

      SECTION 4.3 Application of Collections. For the purposes of this
Agreement, as of the close of business on the last day of each Collection
Period, all collections for the Collection Period with respect to each
Receivable (other than a Purchased Receivable) shall be applied by the Servicer
first to the amount of interest accrued on such Receivable to the date of
receipt, then to reduce the scheduled principal amount outstanding on the
Receivable to the extent of the remaining scheduled payment and then to any
outstanding fees under the terms of the Receivable. Amounts paid by the
Depositor, the Seller or the Servicer in respect of Purchased Receivables shall
be allocated first to any interest accrued on the related Receivable and then to
the Principal Balance of the related Receivable.

      SECTION 4.4 Advances. (a) As of each Determination Date, the Servicer
shall make a payment with respect to each Receivable (other than a Defaulted
Receivable) equal to the excess, if any, of (x) the product of the Principal
Balance of such Receivable as of the first day of the related Collection Period
and one-twelfth of the Annual Percentage Rate (as adjusted downward, as the case
may be, in accordance with the Servicemembers Civil Relief Act or pursuant to
Section 3.2) on such Receivable (calculated on the basis of a 360-day year of
twelve 30-day months), over (y) the interest actually received by the Servicer
with respect to such Receivable from the Obligor or from payment of the Purchase
Amount during or with respect to such Collection Period. The Servicer shall
deposit all such Advances into the Collection Account in immediately available
funds no later than, 11:00 a.m. New York City time, on the Determination Date.
Notwithstanding the foregoing, the Servicer may elect not to make any Advance
with respect to a Receivable to the extent that the Servicer, in its sole
discretion, shall determine that such Advance is not recoverable from subsequent
payments on such Receivable or from withdrawals from the Reserve Account. To the
extent that the amount set forth in clause (y) above with respect to a
Receivable is greater than the amount set forth in clause (x) above with respect
thereto, such excess amount shall be distributed to the Servicer pursuant to
Section 4.6(b). In addition, in the event that a Receivable becomes a Defaulted
Receivable, Outstanding Advances in respect of that Receivable shall be
reimbursed to the extent of interest Collections with respect to such Receivable
and, if such amounts are insufficient, from amounts on deposit in the Reserve
Account, and if such amounts are not sufficient, from amounts on deposit in the
Collection Account. The Servicer shall not make any advance with respect to
principal of Receivables.

      (b) The Servicer shall deposit in the Collection Account the aggregate
Advances on the Receivables pursuant to Section 4.4(a). To the extent that the
Servicer fails to make an Advance pursuant to Section 4.4(a) on the date
required, the Servicer shall so notify the Issuer

                                       16
<PAGE>

and the Indenture Trustee in writing specifying the amount of the Advance and
the Receivable to which such Advance related, and the Indenture Trustee shall
withdraw such amount (or, if determinable by the Servicer, such portion of such
amount as does not represent advances for delinquent interest) from the Reserve
Account and deposit such amount in the Collection Account.

      SECTION 4.5 Additional Deposits. (a) The Depositor and the Servicer shall
deposit in the Collection Account the aggregate Purchase Amounts with respect to
Purchased Receivables pursuant to Sections 2.3 and 3.7, respectively, and the
Servicer shall deposit therein all Purchase Amounts to be paid under Section
8.1. All such deposits with respect to a Collection Period shall be made, in
immediately available funds, on the Business Day preceding the Payment Date
related to such Collection Period (or in the case of the Special Payment Date,
the Business Day preceding the Special Payment Date).

      (b) The Indenture Trustee, in accordance with the written instructions of
the Servicer, shall, on each Payment Date, and the Special Payment Date to the
extent such amounts are for distribution to the Class A-1 Notes, make a
withdrawal from the Reserve Account (i) first, in an amount equal to the Reserve
Account Excess Amount for such Payment Date and (ii) second, in an amount equal
to the amount (if positive) calculated by the Servicer pursuant to the second
sentence of Section 4.6(b).

      SECTION 4.6 Distributions. (a) On each Payment Date, the Indenture Trustee
shall cause the transfer and distribution of the amounts set forth in the
Servicer's Certificate for such Payment Date from the Collection Account to the
Servicer, in immediately available funds, for repayment of Outstanding Advances
pursuant to Section 4.4(a).

      (b) The Servicer shall on or before each Determination Date calculate the
Available Collections, the Reserve Account Excess Amount, the Available Funds,
the Servicing Fee and all unpaid Servicing Fees from prior Collection Periods,
if any, the Accrued Class A Note Interest, the Accrued Class B Note Interest,
the First Priority Principal Payment, if any, and the Regular Principal
Distribution Amount. In addition, the Servicer shall calculate on or before each
Determination Date the difference, if any, between the Total Required Payment
and the Available Funds and, pursuant to Section 4.5(b), the Indenture Trustee
shall withdraw funds from the Reserve Account in an amount equal to the lesser
of such difference (if positive) or the balance of such Reserve Account.

      (c) On each Payment Date, the Servicer shall instruct the Indenture
Trustee (based on the information contained in the Servicer's Certificate
delivered on or before the related Determination Date pursuant to Section 3.9),
to make the following withdrawals from the Collection Account and make deposits,
distributions and payments, to the extent of Available Funds for such Payment
Date (plus funds, if any, deposited in the Collection Account from the Reserve
Account pursuant to Section 4.5(b)), in the following order of priority:

            (i) first, to the Servicer, the Servicing Fee and all unpaid
      Servicing Fees from prior Collection Periods;

            (ii) second, to the Class A Noteholders, the Accrued Class A Note
      Interest for such Payment Date; provided that if there are not sufficient
      funds available to pay the entire amount of the Accrued Class A Note
      Interest, the amounts available shall be applied to the payment of such
      interest on the Class A Notes on a pro rata basis;

            (iii) third, to the Class A Noteholders, the First Priority
      Principal Payment, if any, for such Payment Date to be distributed in the

      Interest for such Payment Date;

            (v) fifth, to the Principal Distribution Account, the Regular
      Principal Distribution Amount (less any amounts distributed under clause
      (iii) above) for such Payment Date;

            (vi) sixth, if such Payment Date is a Final Scheduled Payment Date
      for any Class, to the Principal Distribution Account, the amount necessary
      to reduce the remaining principal amount of such Class to zero after
      giving effect to the amount, if any, to be applied on such Payment Date to
      such Class from funds deposited pursuant to clauses (iii) and (v) above;

            (vii) seventh, to the Reserve Account, the amount, if any, required
      to reinstate the amount in the Reserve Account up to the Specified Reserve

            (viii) eighth, to the Indenture Trustee and the Owner Trustee, all

      of the Indenture and Section 7.1 of the Trust Agreement, respectively, and
      not previously paid; and

                 (A) if the Notes have been accelerated after an Event of
          Default specified in Section 5.1(iii) of the Indenture, then the

                        available shall be applied to the payment of such
                        interest on the Class A Notes on a pro rata basis;

                     (4)to the Class A Noteholders, the First Priority Principal

Servicer to the Indenture Trustee pursuant to Section 4.6(c) and Section 4.6(d)
(based on the information contained in the Servicer's Certificate delivered on
or before the related Determination Date pursuant to Section 3.9) shall specify
that on the Special Payment Date, distributions shall be made from the
Collection Account and the Principal Distribution Account in respect of the
Class A-1 Notes. The portion of the Available Funds (plus funds, if any,
deposited in the Collection Account from the Reserve Account pursuant to Section
4.5(b)) distributed from the Collection Account and the Principal Distribution
Account in respect of the Class A-1 Notes on the Special Payment Date, shall be
allocated in the order and priority set forth in Section 4.6(c) and Section
4.6(d) as though such amounts were to be distributed on the December 2007
Payment Date.

      SECTION 4.7 Reserve Account. (a) (i) The Servicer shall, prior to the
Closing Date, cause to be established and maintained an Eligible Deposit Account
in the name "The Bank of New York, as Indenture Trustee, as secured party from
USAA Auto Owner Trust 2006-4", initially at the corporate trust department of
the Indenture Trustee, which shall be designated as the "Reserve Account" (the
Reserve Account, together with the Collection Account (including the Principal
Distribution Account), the "Trust Accounts"). The Reserve Account shall be under
the sole dominion and control of the Indenture Trustee; provided, that the
Servicer may make deposits to the Reserve Account in accordance with the Basic
Documents. The Reserve Account will be established and maintained pursuant to an
account agreement which specifies New York law as the governing law. In
addition, the Reserve Account shall be established and maintained at an
institution which agrees in writing that for so long as the Notes are
Outstanding it will comply with entitlement orders (as defined in Article 8 of
the UCC) originated by the Indenture Trustee without further consent of the
Issuer. On the Closing Date, the Depositor shall deposit the Reserve Initial
Deposit into the Reserve Account. The Reserve Account and all amounts,
securities, investments, financial assets and other property deposited in or
credited to the Reserve Account (such amounts, the "Reserve Account Property")
shall be held by the Indenture Trustee as secured party for the benefit of the
Noteholders and, after payment in full of the Notes, as agent of the Owner
Trustee and as part of the Trust Property, and all deposits to and withdrawals
from there from shall be made only upon the terms and conditions of the Basic
Documents.

      The Reserve Account Property shall, to the extent permitted by applicable
law, rules and regulations, be invested, as directed in writing by holders of
Certificates holding not less than a majority of the Percentage Interests
evidenced by the Certificates, by the bank or trust company then maintaining the
Reserve Account in Permitted Investments that mature not later than the next
Payment Date (or in the case of the Special Payment Date, the portion of such
funds needed to make final payment on the Class A-1 Notes shall mature not later
than the Business Day immediately prior to the Special Payment Date) or such
later date that satisfies the Rating Agency Condition, and such Permitted
Investments shall be held to maturity. If The Bank of New York is the Indenture
Trustee, in the absence of written direction, all funds shall be retained

                                       21
<PAGE>

uninvested. Additionally, amounts in the Reserve Account will be retained
uninvested in the circumstances described in Section 8.3(c) of the Indenture.
All interest and other income (net of losses and investment expenses) on funds
on deposit in the Reserve Account shall be deposited therein. The Indenture
Trustee shall not be liable for investment losses in Permitted Investments made
in accordance with directions from the investment instructions received from
holders of the Certificates as provided above. In the event the Reserve Account
is no longer to be maintained at the corporate trust department of the Indenture
Trustee, the Servicer shall, with the Indenture Trustee's or Owner Trustee's
assistance as necessary, cause an Eligible Deposit Account to be established as
the Reserve Account within ten (10) Business Days (or such longer period not to
exceed thirty (30) calendar days as to which each Rating Agency may consent) and
give written notice of the location and account number of such account to the
Indenture Trustee.

            (ii) With respect to Reserve Account Property:

                  (A) any Reserve Account Property that is a "financial asset"
            as defined in Section 8-102(a)(9) of the UCC shall be physically
            delivered to, or credited to an account in the name of, the
            institution maintaining the Reserve Account in accordance with such
            institution's customary procedures such that such institution
            establishes a "securities entitlement" in favor of the Indenture
            Trustee with respect thereto; and

                  (B) any Reserve Account Property that is held in deposit
            accounts shall be held solely in the name of the Indenture Trustee
            at one or more depository institutions having the Required Rating
            and each such deposit account shall be subject to the exclusive
            custody and control of the Indenture Trustee and the Indenture
            Trustee shall have sole signature authority with respect thereto.

            (iii) Except for any deposit accounts specified in clause (ii)(B)
      above, the Reserve Account shall only be invested in securities or in
      other assets which the institution maintaining the Reserve Account agrees
      to treat as "financial assets" as defined in Section 8-102(a)(9) of the
      UCC.

      (b) If the Servicer pursuant to Section 4.4 determines on or before any
Determination Date that it is required to make an Advance and does not do so
from its own funds, the Servicer shall promptly instruct the Indenture Trustee
in writing to draw funds, in an amount specified by the Servicer, from the
Reserve Account and deposit them in the Collection Account to cover any
shortfall. Such payment shall be deemed to have been made by the Servicer
pursuant to Section 4.4 for purposes of making distributions pursuant to this
Agreement, but shall not otherwise satisfy the Servicer's obligation to deliver
the amount of the Advances to the Indenture Trustee, and the Servicer shall
within two (2) Business Days replace any funds in the Reserve Account so used.

      (c) Following the payment in full of the aggregate principal amount of the
Notes and of all other amounts owing or to be distributed hereunder or under the
Indenture or the Trust Agreement to Noteholders, the Indenture Trustee and the
Owner Trustee, any remaining Reserve Account Property shall be distributed to
the Certificate Distribution Account.

remit collections on a monthly basis rather than within two (2) Business Days of
receipt, the Bank may make the remittances pursuant to Sections 4.2 and 4.5
above, net of amounts to be distributed to the Bank pursuant to Section 4.6(c).
Nonetheless, the Servicer shall account for all of the above described

Servicer's Certificate as if the amounts were deposited and/or transferred

      (a) The Depositor makes the following representations and warranties on
which the Issuer is deemed to have relied in acquiring the Trust Property. The

Trustee pursuant to the Indenture:

      (i) Organization and Good Standing. The Depositor is a limited liability
company duly formed, validly existing and in good standing under the laws of the
State of Delaware, with all requisite power and authority to own its properties
and to conduct its business as such properties are currently owned and such
business is presently conducted, and had at all relevant times, and has, power,
authority, and legal right to acquire and own the Receivables.

      (ii) Power and Authority. The Depositor has all requisite power and
authority to execute and deliver this Agreement and the other Basic Documents to
which it is a party and to carry out their terms; the Depositor has full power
and authority to sell and assign the property to be sold, and assigned to and
deposited with the Issuer, and the Depositor shall have duly authorized such
sale and assignment to the Issuer by all necessary limited liability company
action; and the execution, delivery, and performance of this Agreement and the
other Basic Documents to which the Depositor is a party have been duly
authorized, executed and delivered by the Depositor by all necessary limited
liability company action.

      (iii) Binding Obligations. This Agreement, when duly executed and
delivered by the other parties hereto, constitutes a legal, valid, and binding
obligation of the Depositor enforceable against the Depositor in accordance with
its terms, except as the enforceability hereof may be limited by bankruptcy,
insolvency, reorganization, or other similar laws affecting creditors' rights in
general and by general principles of equity, regardless of whether such
enforceability is considered in a proceeding in equity or at law.

      (iv) No Violation. The consummation of the transactions contemplated by
this Agreement and the other Basic Documents to which the Depositor is a party
and the fulfillment of the terms hereof and thereof do not (i) conflict with,
result in any breach of any of the terms and provisions of, or constitute (with
or without notice or lapse of time) a default under, the limited liability
company agreement of the Depositor, 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 Depositor is a party or by which it is bound, (ii) result in the creation or
imposition of any lien upon any of its properties pursuant to the terms of any
such indenture, agreement, or other instrument, or (iii) violate any law or, to
the best of the Depositor's knowledge, any order, rule, or regulation applicable
to the

                                       25
<PAGE>

Depositor of any court or of any federal or state regulatory body,
administrative agency, or other governmental instrumentality having jurisdiction
over the Depositor or its properties.

      (v) No Proceedings. There are no proceedings or investigations pending,
or, to the best of the Depositor's knowledge, threatened, before any court,
regulatory body, administrative agency, or other governmental instrumentality
having jurisdiction over the Depositor or its properties (i) asserting the

Securities, (ii) seeking to prevent the issuance of the Securities or the
consummation of any of the transactions contemplated by this Agreement or the

the other Basic Documents or the Securities or (iv) relating to the Depositor
and which might adversely affect the federal income tax attributes of the
Securities.

      (vi) Security Interest Representation. This Agreement creates a valid and
continuing security interest (as defined in the applicable UCC) in the
Receivables that is in existence in favor of the Issuer, which security interest
is prior to all other liens, and is enforceable as such as against creditors of
and purchasers from the Depositor, which security interest will be assigned to

interest granted to the Issuer, the Depositor has not pledged, assigned,
transferred or sold, a security interest in, or otherwise conveyed any of the

lien filing against it.

original sale of the Notes and the Certificates, including any sales, gross
receipts, general corporation, tangible personal property, privilege, or license
taxes (but, in the case of the Issuer, not including any taxes asserted with
respect to ownership of the Receivables or federal or state income taxes arising
out of the transactions contemplated by this Agreement and the other Basic

the performance of its duties under this Agreement, or by reason of reckless
disregard of its obligations and duties under this Agreement and (ii) the

will be the successor to the Depositor under this Agreement without the
execution or filing of any document or any further act on the part of any of the
parties to this Agreement. The Depositor shall provide notice of any merger,
conversion, consolidation, or succession pursuant to this Section 5.3 to the
Rating Agencies.

      SECTION 5.4 Limitation on Liability of Depositor and Others. The Depositor
and any officer or employee or agent of the Depositor may rely in good faith on
the advice of counsel or on any document of any kind, prima facie properly
executed and submitted by any Person respecting any matters arising hereunder.

defend any legal action that shall not be incidental to its obligations under
this Agreement, and that in its opinion may involve it in any expense or
liability.

      SECTION 5.5 Depositor May Own Notes or Certificates. The Depositor, and
any Affiliate of the Depositor, may in its individual or any other capacity
become the owner or pledgee of Notes or Certificates with the same rights as it

otherwise expressly provided herein or in the other Basic Documents. Except as
set forth herein or in the other Basic Documents, Notes and Certificates so
owned by or pledged to the Depositor or any such Affiliate shall have an equal
and proportionate benefit under the provisions of this Agreement and the other

Certificateholders, except as provided under this Agreement, for any action
taken or for refraining from the taking of any action pursuant to this Agreement
or for errors in judgment; provided, however, that this provision shall not
protect the Servicer or any such Person against any liability that would
otherwise be imposed by reason of willful misfeasance or bad faith in the
performance of duties or by reason of reckless disregard of obligations and
duties under this Agreement, or by reason of negligence in the performance of
its duties under this Agreement. The Servicer and any director, officer or
employee or agent of the Servicer may rely in good faith on any Opinion of

any obligation to appear in, prosecute, or defend any legal action that shall
not be incidental to its duties to service the Receivables in accordance with

liability; provided, however, that the Servicer may undertake any reasonable
action that it may deem necessary or desirable in respect of this Agreement and
the rights and duties of the parties to this Agreement and the interests of the
Noteholders and Certificateholders under this Agreement. In such event, the
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Issuer, and the Servicer shall
be entitled to be reimbursed therefor. Any amounts due the Servicer

pursuant to this subsection shall be payable on a Payment Date from the
Available Collections on deposit in the Collection Account only after all
payments required to be made on such date to the Noteholders, the
Certificateholders and the Servicer have been made, and deposits of any amount
required to be deposited into the Reserve Account pursuant to Section 4.6(c)(vi)
to maintain the amount on deposit therein (exclusive of investment income and
earnings on amounts on deposit therein) at the Specified Reserve Balance on such
date have been made.

Servicer's duties under this Agreement, other than (i) any loss or liability
otherwise reimbursable pursuant to this Agreement; (ii) any loss, liability, or
expense incurred solely by reason of the Servicer's willful misfeasance,
negligence, or bad faith in the performance of its duties hereunder or by reason

specific duties as servicer under this Agreement through sub-contractors;

its responsibilities with respect to such duties as to which the Servicer shall
remain primarily responsible and the Servicer shall be solely responsible for
the fees of any such sub-contractors.

      SECTION 6.6 Servicer Not to Resign as Servicer. Subject to the provisions
of Section 6.3, the Servicer shall not resign from its obligations and duties
under this Agreement except upon determination that the performance of its
duties under this Agreement shall no longer be permissible under applicable law.
Notice of any such determination permitting the resignation of the Servicer
shall be communicated to the Owner Trustee, the Indenture Trustee and the
Depositor at the earliest practicable time (and, if such communication is not in
writing, shall be confirmed in writing at the earliest practicable time) and any
such determination shall be evidenced by an Opinion of Counsel to such effect
delivered to the Owner Trustee and the Indenture Trustee concurrently with or
promptly after such notice. No such resignation shall become effective until the
Indenture Trustee or a Successor Servicer shall have (i) taken the actions
required by Section 7.1(b), (ii) assumed the responsibilities and obligations of

      SECTION 7.1 Events of Servicing Termination. (a) If any one of the
following events ("Events of Servicing Termination") shall occur and be
continuing:

            (i) Any failure by the Servicer (or, so long as the Seller is the

      Trustee any proceeds or payment required to be so delivered under the
      terms of the Notes and the Certificates and this Agreement that shall
      continue unremedied for a period of five (5) Business Days after written
      notice of such failure is received by the Servicer or the Seller, as the
      case may be, from the Owner Trustee or the Indenture Trustee or after
      discovery of such failure by an officer of the Servicer or the Seller, as
      the case may be; or

            (ii) Failure on the part of the Servicer (or, so long as the Seller
      is the Servicer, the Seller) duly to observe or to perform in any material
      respect any other covenants or agreements, as the case may be, set forth
      in the Notes, the Certificates or in this Agreement, which failure shall
      (A) materially and adversely affect the rights of Noteholders or
      Certificateholders and (B) continue unremedied for a period of ninety (90)
      days after the date on which written notice of such failure, requiring the
      same to be remedied, shall have been given (1) to the Servicer or the
      Seller, as the case may be, by the Owner Trustee or the Indenture Trustee,
      or (2) to the Owner Trustee, the Indenture Trustee, the Seller and the
      Servicer by the Noteholders of Notes evidencing not less than 25% of the

      liabilities, or similar proceedings, or for the winding up or liquidation
      of its respective affairs, and the continuance of any such decree or order

      or the Servicer shall admit in writing its inability to pay its debts
      generally as they become due, file a petition to take advantage of any
      applicable insolvency or reorganization statute, make an assignment for
      the benefit of its creditors, or voluntary suspend payment of its
      obligations or become insolvent;

then the Indenture Trustee shall promptly notify each Rating Agency, and in each
and every case, so long as an Event of Servicing Termination shall not have been
remedied, either the Indenture Trustee or the holders of Notes evidencing not
less than a majority of the principal amount of the Controlling Class

than a majority of the Percentage Interests evidenced by the Certificates), by
notice then given in writing to the Servicer (and to the Indenture Trustee and
the Owner Trustee if given by the Noteholders and to the Owner Trustee if given
by the Certificateholders) (with a copy to the Rating Agencies) may terminate
all of the rights and obligations of the Servicer under this Agreement. On or
after the receipt by the Servicer of such written notice, all authority and
power of the Servicer under this Agreement, whether with respect to the Notes,
the Certificates or the Trust Property or otherwise, shall pass to and be vested
in the Indenture Trustee or such Successor Servicer as may be appointed under
Section 7.2; and, without limitation, the Indenture Trustee and the Owner
Trustee are hereby authorized and empowered to execute and deliver, on behalf of
the predecessor Servicer, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement of the Receivables
and related documents, or otherwise.

      (b) Upon termination of the Servicer under Section 7.1(a), the predecessor
Servicer shall cooperate with the Indenture Trustee, the Owner Trustee and such

deposit, or shall thereafter be received with respect to a Receivable and the
delivery of the Receivable Files and the related accounts and records maintained
by the Servicer. All reasonable costs and expenses (including attorneys' fees)
incurred in connection with transferring the Receivable Files to the Successor
Servicer and amending this Agreement to reflect such succession as Servicer
pursuant to this Section 7.1 shall be paid by the predecessor Servicer upon
presentation of reasonable documentation of such costs and expenses.

      SECTION 7.2 Appointment of Successor Servicer. (a) Upon the Servicer's
receipt of notice of termination pursuant to Section 7.1 or the Servicer's
resignation in accordance with the terms of this Agreement, the predecessor
Servicer shall continue to perform its functions as Servicer under this
Agreement, in the case of termination, only until the date specified in such
termination notice or, if no such date is specified in a notice of termination,
until receipt of such notice and, in the case of resignation, until the later of
(x) the date 90 days from the delivery to the Indenture Trustee and the Owner
Trustee of written notice of such resignation (or written confirmation of such
notice) in accordance with the terms of this Agreement and (y) the date upon
which the predecessor Servicer shall become unable to act as Servicer, as
specified in the notice of resignation and accompanying Opinion of Counsel. In
the event of the Servicer's resignation or termination hereunder, the Issuer
shall appoint a Successor Servicer, and the

                                       33
<PAGE>

Successor Servicer shall accept its appointment by a written assumption in form
acceptable to the Owner Trustee and the Indenture Trustee (with a copy to each
Rating Agency) and shall provide the Depositor in writing with such information
as reasonably requested by the Depositor to comply with its reporting
obligations under the Exchange Act with respect to a replacement servicer. In
the event that a Successor Servicer has not been appointed at the time when the
predecessor Servicer has ceased to act as Servicer in accordance with this
Section 7.2, the Indenture Trustee without further action shall automatically be
appointed the Successor Servicer and the Indenture Trustee shall be entitled to
the Servicing Fee and shall provide the Depositor in writing with such
information as reasonably requested by the Depositor to comply with its
reporting obligations under the Exchange Act with respect to a Master Servicer.
The Indenture Trustee may resign as the Servicer by giving written notice of
such resignation to the Issuer and in such event shall be released from such
duties and obligations, such release not to be effective until the date a
Successor Servicer enters into a written assumption as provided in this Section.
Upon delivery of any such notice to the Issuer, the Issuer shall obtain a new
servicer as the Successor Servicer in accordance with this Section.
Notwithstanding the above, if the Indenture Trustee shall be legally unable so
to act or if, within 30 days after the delivery of its notice of resignation,
the Issuer shall not have obtained a Successor Servicer, the Indenture Trustee
shall appoint, or petition a court of competent jurisdiction to appoint, any
established institution, having a net worth of not less than $100,000,000 and
whose regular business shall include the servicing of automotive receivables, as
the successor to the Servicer under this Agreement; provided that the Rating
Agency Condition shall be satisfied in connection with such appointment.

      (b) Upon appointment, the Successor Servicer shall be the successor in all
respects to the predecessor Servicer and shall be subject to all the
responsibilities, duties, and liabilities arising thereafter relating thereto
placed on the predecessor Servicer, by the terms and provisions of this
Agreement.

      (c) In connection with such appointment, subject to Section 3.7(e) of the
Indenture, the Indenture Trustee may make such arrangements for the compensation
of such Successor Servicer out of payments on Receivables as it and such
Successor Servicer shall agree; provided, however, that no such compensation
shall be in excess of that permitted the predecessor Servicer under this
Agreement. The Indenture Trustee and such Successor Servicer shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

      SECTION 7.3 Repayment of Advances. If the identity of the Servicer shall
change, the predecessor Servicer shall be entitled to receive to the extent of
available funds reimbursement for Outstanding Advances pursuant to Section 4.3
and 4.4, in the manner specified in Section 4.6, with respect to all Advances
made by the predecessor Servicer.

      SECTION 7.4 Notification to Noteholders and Certificateholders. Upon any
termination of, or appointment of a successor to, the Servicer pursuant to this
Article VII, the Indenture Trustee shall give prompt written notice thereof to
Noteholders, and the Owner Trustee shall give prompt written notice thereof to
Certificateholders at their respective addresses of record and to each Rating
Agency.

      SECTION 7.5 Waiver of Past Events of Servicing Termination. The holders of
Notes evidencing not less than a majority of the principal amount of the
Controlling Class (or, if no Notes are Outstanding, holders of Certificates
evidencing not less than a majority of the Percentage Interests evidenced by the
Certificates) may, on behalf of all Noteholders and Certificateholders, waive
any Event of Servicing Termination hereunder and its consequences, except an
event resulting from the failure to make any required deposits to or payments
from any of the Trust Accounts or the Certificate Distribution Account in
accordance with this Agreement, which shall require the unanimous vote of all
Holders of Outstanding Securities. Upon any such waiver of a past Event of
Servicing Termination, such Event of Servicing Termination shall cease to exist,
and shall be deemed to have been remedied for every purpose of this Agreement.
No such waiver shall extend to any subsequent or other event or impair any right
consequent thereon. The Issuer shall provide written notice of any such waiver
to the Rating Agencies.

                                  ARTICLE VIII

                                   TERMINATION

      SECTION 8.1 Optional Purchase of All Receivables. As of the last day of
any Collection Period as of which the Pool Factor shall be equal to or less than
the Optional Purchase Percentage, the Servicer shall have the option to purchase
the Trust Property from the Trust. To exercise such option, the Servicer shall
deposit pursuant to Section 4.5 in the Collection Account an amount equal to the
lesser of (i) the aggregate Purchase Amount for the Receivables and (ii) the
fair market value of the Receivables, and shall succeed to all interests in and
to the Trust. Notwithstanding the foregoing, the Servicer shall not be permitted
to exercise such option unless the amount to be deposited in the Collection
Account pursuant to the preceding sentence is greater than or equal to the sum
of the outstanding principal amount of the Notes and all accrued but unpaid
interest (including any over due interest) thereon. The amount deposited in the
Collection Account pursuant to this Section 8.1 shall be used on the next
Payment Date to make payments in full to Noteholders and Certificateholders in
the manner set forth in Article IV. The purchase of the Trust Property pursuant
to this Section shall not be permitted unless either (i) the Servicer's
long-term unsecured debt is rated at the time of such purchase at least Baa3 by
Moody's or (ii) the Servicer provides to the Indenture Trustee and the Owner
Trustee an Opinion of Counsel in form reasonably satisfactory to the Indenture
Trustee and the Owner Trustee and in form and substance satisfactory to Moody's
to the effect that such purchase will not constitute a fraudulent transfer of
assets of the Servicer under applicable state and federal law; provided that
this sentence may be deleted or modified with the consent of Moody's and without
the consent of any Securityholder, the Indenture Trustee or the Owner Trustee.

      SECTION 8.2 Succession Upon Satisfaction and Discharge of Indenture.
Following the satisfaction and discharge of the Indenture and the payment in
full of the principal of and interest on the Notes, to the extent permitted by
applicable law and until the payment of all amounts owing or to be distributed
hereunder to the Certificateholders, the Indenture Trustee will continue to
carry out its obligations hereunder as agent for the Owner Trustee, including
without limitation making distributions from the Collection Account in
accordance with Section 4.6, making withdrawals from the Reserve Account in
accordance with Section 4.5(b) and Section 4.7.

the consent of any of the Noteholders or the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions in this Agreement, or to add
any provisions to or change or eliminate any provisions or to modify the rights

lieu thereof whether or not notation of such consent is made upon such Note or
the Certificate), 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 or the Certificateholders; provided,
however, that no such amendment shall (A) increase or reduce in any manner the

Trustee and the Indenture Trustee shall be entitled to receive and rely upon an
Opinion of Counsel stating that the execution of such amendment is authorized or

the meaning of ss. 9-506 of the UCC, unless it shall have given the Owner
Trustee and the Indenture Trustee at least 10 days' prior written notice
thereof, with a copy to the Rating Agencies, and shall have promptly filed
appropriate amendments to all previously filed financing statements or
continuation statements.

      (c) The Depositor, the Seller and the Servicer shall give the Owner
Trustee and the Indenture Trustee at least ten (10) days' prior written notice
of any relocation of its principal executive office or change in the

Receivable shall have been paid in full or repurchased.

      (f) If at any time the Seller or the Servicer shall propose to sell, grant
a security interest in, or otherwise transfer any interest in automotive
receivables to any prospective purchaser, lender, or other transferee, the
Servicer shall give to such prospective purchaser, lender, or other transferee
computer tapes, records, or print-outs (including any restored from back-up
archives) that, if they shall refer in any manner whatsoever to any Receivable,

the Issuer and has been pledged to the Indenture Trustee.

      (g) The Servicer, upon receipt of reasonable prior notice, shall permit
the Owner Trustee, the Indenture Trustee and their respective agents at any time

the Noteholders or the Certificateholders, any right, remedy, power or privilege
hereunder, shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, remedy, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges therein provided are
cumulative and not exhaustive of any rights, remedies, powers and privileges
provided by law.

      SECTION 9.9 Third-Party Beneficiaries. This Agreement will inure to the
benefit of and be binding upon the parties hereto, the Indenture Trustee and the
Owner Trustee and their respective successors and permitted assigns and each of
the Indenture Trustee and the Owner Trustee may enforce the provisions hereof as
if they were parties thereto. Except as otherwise provided in this Article IX,
no other Person will have any right or obligation hereunder. The parties hereto
hereby acknowledge and consent to the pledge of this Agreement by the Issuer to
the Indenture Trustee for the benefit of the Noteholders pursuant to the
Indenture.

      SECTION 9.10 Actions by Noteholders or Certificateholders. (a) Wherever in
this Agreement a provision is made that an action may be taken or a notice,
demand, or instruction given by Noteholders or Certificateholders, such action,
notice, or instruction may be taken or given by any Noteholder or
Certificateholder, as applicable, unless such provision requires a specific
percentage of Noteholders or Certificateholders.

      (b) Any request, demand, authorization, direction, notice, consent,
waiver, or other act by a Noteholder or Certificateholder shall bind such
Noteholder or Certificateholder and every subsequent holder of such Note or
Certificate issued upon the registration of transfer

                                       40
<PAGE>

thereof or in exchange therefor or in lieu thereof in respect of anything done
or omitted to be done by the Owner Trustee, the Indenture Trustee or the
Servicer in reliance thereon, whether or not notation of such action is made
upon such Note or Certificate.

      SECTION 9.11 Limitation of Liability of Owner Trustee and Indenture
Trustee. (a) Notwithstanding anything contained herein to the contrary, this
Agreement has been countersigned by Wells Fargo Delaware Trust Company not in
its individual capacity but solely in its capacity as Owner Trustee of the
Issuer and in no event shall Wells Fargo Delaware Trust Company, in its
individual capacity or, except as expressly provided in the Trust Agreement, as
Owner Trustee of the Issuer have any liability for the representations,
warranties, covenants, agreements or other obligations of the Issuer hereunder
or in any of the certificates, notices or agreements delivered pursuant hereto,
as to all of which recourse shall be had solely to the assets of the Issuer. For
all purposes of this Agreement, in the performance of its duties or obligations
hereunder or in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Articles VI and VII of the Trust Agreement.

      (b) Notwithstanding anything contained herein to the contrary, this
Agreement has been accepted by The Bank of New York, not in its individual
capacity but solely as Indenture Trustee, and in no event shall The Bank of New
York, have any liability for the representations, warranties, covenants,
agreements or other obligations of the Issuer hereunder or in any of the
certificates, notices or agreements delivered pursuant hereto, as to all of
which recourse shall be had solely to the assets of the Issuer. For all purposes
of this Agreement, in the performance of its duties or obligations hereunder or
in the performance of any duties or obligations of the Issuer hereunder, the
Indenture Trustee shall be subject to, and entitled to the benefits of, the
terms and provisions of Article VI of the Indenture.

      SECTION 9.12 Savings Clause. It is the intention of the Depositor and the
Issuer that the transfer of the Trust Property contemplated herein constitute an
absolute transfer of the Trust Property, conveying good title to the Trust
Property from the Depositor to the Issuer. However, in the event that such
transfer is deemed to be a pledge or other transfer for security, the Depositor
hereby grants to the Issuer a first priority security interest in all of the
Depositor's right, title and interest in, to and under the Trust Property, and
all proceeds thereof, to secure a loan in an amount equal to all amounts payable
under the Notes and the Certificates, and in such event, this Agreement shall
constitute a security agreement under applicable law.

                             EXCHANGE ACT REPORTING

      SECTION 10.1 Further Assurances. The Indenture Trustee, the Owner Trustee
and the Servicer shall reasonably cooperate with the Depositor in connection
with the satisfaction of the Depositor's reporting requirements under the
Exchange Act with respect to the Trust. The Depositor shall not exercise its
right to request delivery of information or other performance under these
provisions other than in good faith. In addition to the information specified
below, if so requested by the Depositor for the purpose of satisfying its
reporting obligation under the Exchange Act, the Indenture Trustee, the Owner
Trustee and the Servicer shall provide the

                                       41
<PAGE>

Depositor with (a) such information which is available to such Person without
unreasonable effort or expense and within such timeframe as may be reasonably
requested by the Depositor to comply with the Depositor's reporting obligations
under the Exchange Act and (b) to the extent such Person is a party (and the
Depositor is not a party) to any agreement or amendment required to be filed,
copies of such agreement or amendment in EDGAR-compatible form. Each of the
Servicer, the Indenture Trustee and the Owner Trustee acknowledges that
interpretations of the requirements of Regulation AB may change over time,
whether due to interpretive guidance provided by the Commission or its staff,
consensus among participants in the asset-backed securities markets, advice of
counsel, or otherwise, and agrees to comply with requests made by the Depositor
in good faith for delivery of information under these provisions on the basis of
evolving interpretations of Regulation AB.

      SECTION 10.2 Form 10-D Filings. So long as the Depositor is required to
file Exchange Act Reports with respect to the Issuer, no later than each Payment
Date, each of the Indenture Trustee, the Owner Trustee and the Servicer shall
notify (and the Servicer shall cause any Subservicer to notify) the Depositor of
any Form 10-D Disclosure Item with respect to such Person, together with a
description of any such Form 10-D Disclosure Item in form and substance
reasonably acceptable to the Depositor. In addition to such information as the
Servicer is obligated to provide pursuant to other provisions of this Agreement,
if so requested by the Depositor, the Servicer shall provide such information
which is available to the Servicer, without unreasonable effort or expense
regarding the performance or servicing of the Receivables as is reasonably
required to facilitate preparation of distribution reports in accordance with
Item 1121 of Regulation AB. Such information shall be provided concurrently with
the Statements to Noteholders pursuant to Section 4.9, commencing with the first
such report due not less than five Business Days following such request.

      SECTION 10.3 Form 8-K Filings. So long as the Depositor is required to
file Exchange Act Reports with respect to the Issuer, each of the Indenture
Trustee, the Owner Trustee and the Servicer shall promptly notify the Depositor,
but in no event later than one (1) Business Day after its occurrence, of any
Reportable Event (in the case of the Owner Trustee, only an event in clause (d)
of the definition of "Reportable Event") of which such Person (or in the case of
the Owner Trustee and the Indenture Trustee, a Responsible Officer of such
Person) has actual knowledge. Each Person shall be deemed to have actual
knowledge of any such event to the extent that it relates to such Person or any
action or failure to act by such Person.

      SECTION 10.4 Form 10-K Filings. So long as the Depositor is required to
file Exchange Act Reports: (i) if the Item 1119 Parties listed on Appendix B
have changed since the Closing Date, no later than March 1 of each year, the
Depositor shall provide each of the Indenture Trustee, the Owner Trustee and the
Servicer with an updated Appendix B setting forth the Item 1119 Parties and (ii)
no later than March 15 of each year, commencing in 2007, the Indenture Trustee,
the Owner Trustee and the Servicer shall notify the Depositor of any Form 10-K
Disclosure Item, together with a description of any such Form 10-K Disclosure
Item in form and substance reasonably acceptable to the Depositor.

      SECTION 10.5 Report on Assessment of Compliance and Attestation. So long
as the Depositor is required to file Exchange Act Reports, on or before March 15
of each calendar year, commencing in 2007:

      (a) The Indenture Trustee shall deliver to the Depositor and the Servicer
a report of the Indenture Trustee's assessment of compliance with the Servicing
Criteria during the immediately preceding calendar year, as set forth under
Rules 13a-18 and 15d-18 of the Exchange Act (or any successor provisions) and
Item 1122 of Regulation AB. Such report shall be signed by an authorized officer
of the Indenture Trustee and shall at a minimum address each of the Servicing
Criteria specified on a certification substantially in the form of Appendix C
hereto delivered to the Depositor concurrently with the execution of this
Agreement (provided that such certification may be revised after the date of
this Agreement as agreed by the Depositor and the Indenture Trustee to reflect
any guidance with respect to such criteria from the Commission). To the extent
any of the Servicing Criteria are not applicable to the Indenture Trustee, with
respect to asset-backed securities transactions taken as a whole involving the
Indenture Trustee and that are backed by the same asset type backing the Notes,
such report shall include such a statement to that effect. The Indenture Trustee
acknowledges and agrees that the Depositor and the Servicer with respect to its
duties as the Certifying Person, and each of their respective officers and
directors shall be entitled to rely on upon each such servicing criteria
assessment and the attestation delivered pursuant to Section 10.5(b) below.

      (b) The Indenture Trustee shall deliver to the Depositor and the Servicer
a report of a registered public accounting firm that attests to, and reports on,
the assessment of compliance made by the Indenture Trustee and delivered
pursuant to the preceding paragraph. Such attestation shall be in accordance
with Rules 13a-18 and 15d-18 of the Exchange Act (or any successor provisions),
Rules 1-02(a)(3) and 2-02(g) of Regulation S-X (or any successor provisions)
under the Securities Act and the Exchange Act, including, without limitation
that in the event that an overall opinion cannot be expressed, such registered
public accounting firm shall state in such report why it was unable to express
such an opinion. Such report must be available for general use and not contain
restricted use language.

      (c) The Indenture Trustee shall cause each Reporting Subcontractor to
deliver to the Depositor and the Servicer an assessment of compliance and
accountant's attestation as and when provided in paragraphs (a) and (b) of this
Section. An assessment of compliance provided by a Subcontractor need not
address any elements of the Servicing Criteria other than those specified by the
Indenture Trustee pursuant to Section 10.5(a).

      (d) In the event the Indenture Trustee or Reporting Subcontractor is
terminated or resigns during the term of this Agreement, such Person shall
provide the documents and information pursuant to this Section 10.5 with respect
to the period of time it was subject to this Agreement or provided services with
respect to the Trust or the Receivables.

      SECTION 10.6 Back-up Sarbanes-Oxley Certification. No later than March 15
of each year, beginning in 2007, the Indenture Trustee and the Servicer shall
provide to the Person who signs the Sarbanes-Oxley Certification (the
"Certifying Person") a certification (each, a "Performance Certification") and
shall cause each Reporting Subcontractor, in the form attached

                                       43
<PAGE>

hereto as Appendix D (in the case of the Indenture Trustee or a Reporting
Subcontractor) and as Appendix E (in the case of the Servicer) on which the
Certifying Person, the entity for which the Certifying Person acts as an
officer, and such entity's officers, directors and Affiliates (collectively with
the Certifying Person, "Certification Parties") can reasonably rely. No
certifications shall be required under this clause unless the Depositor is
required under the Exchange Act to file an annual report on Form 10-K with
respect to the Trust. So long as the Servicer is an Affiliate of the Depositor,
the Servicer may, but is not required to deliver the Performance Certificate. In
the event that prior to the filing date of the Form 10-K in March of each year,
the Indenture Trustee or the Servicer has actual knowledge of information
material to the Sarbanes-Oxley Certification, the Indenture Trustee or the
Servicer shall promptly notify the Depositor. Each of the Indenture Trustee and
the Servicer agrees to cooperate with all reasonable requests made by any
Certifying Person or Certification Party in connection with such Person's
attempt to conduct any due diligence that such Person reasonably believes to be
appropriate in order to allow it to deliver any Sarbanes-Oxley Certification or
portion thereof with respect to the Trust.

      SECTION 10.7   Use of Subcontractors.

      (a) It shall not be necessary for the Indenture Trustee or the Servicer to
seek the consent of the Depositor or any other party hereto to the utilization
of any Subcontractor. Each of the Indenture Trustee and the Servicer shall
promptly upon request provide to the Depositor (or any designee of the
Depositor, such as the Servicer or the Administrator) a written description (in
form and substance satisfactory to the Depositor) of the role and function of
each Subcontractor utilized by such Person, specifying (i) the identity of each
such Subcontractor, (ii) which (if any) of such Subcontractors are
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB and (iii) which elements of the Servicing Criteria will be
addressed in assessments of compliance provided by each Subcontractor identified
pursuant to clause (ii) of this paragraph. As a condition to the utilization of
any Subcontractor determined to be a Reporting Subcontractor, the Indenture
Trustee shall cause any such Subcontractor for the benefit of the Depositor to
comply with the provisions of Sections 10.5 and 10.6 of this Agreement to the
same extent as if such Subcontractor were the Indenture Trustee. The Indenture
Trustee shall be responsible for obtaining from each Subcontractor and
delivering to the Depositor, any assessment of compliance and attestation
required to be delivered by such Subcontractor under Section 10.5 and Section
10.6, in each case as and when required to be delivered.

      (b) As a condition to the utilization of any Subcontractor determined to
be a Reporting Subcontractor, the Servicer shall cause any such Subcontractor
for the benefit of the Depositor to comply with the provisions of Section
3.10(a)(ii), Section 3.11 and Section 10.6 of this Agreement to the same extent
as if such Subcontractor were the Servicer. The Servicer shall be responsible
for obtaining from each Subcontractor and delivering to the Depositor, any
assessment of compliance and attestation required to be delivered by such
Subcontractor under this Agreement, in each case as and when required to be
delivered.

      SECTION 10.8 Representations and Warranties. Each of the Indenture Trustee
and the Owner Trustee represents that (i) there are no affiliations, relating to
such Person with respect to

                                       44
<PAGE>

any 1119 Party, (ii) there are no relationships or transactions with respect to
any 1119 Party and such Person that are outside the ordinary course of business
or on terms other than would be obtained in an arm's length transaction with an
unrelated third party, apart from the transactions contemplated under the Basic
Documents, and that are material to the investors' understanding of the Notes
and (iii) there are no legal proceedings pending, or known to be contemplated by
governmental authorities, against such Person, or of which the property of such
Person is subject, that is material to the Noteholders.

      SECTION 10.9   Indemnification.

      (a) Each of the Indenture Trustee and the Servicer shall indemnify the
Depositor, each affiliate of the Depositor, the Servicer with respect to its
duties as Certifying Person or each Person who controls any of such parties
(within the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act) and the respective present and former directors, officers,
employees and agents of each of the foregoing, and shall hold each of them
harmless from and against any losses, damages, penalties, fines, forfeitures,
legal fees and expenses and related costs, judgments, and any other costs, fees
and expenses that any of them may sustain arising out of or based upon:

      (i) (A) any untrue statement of a material fact contained or alleged to be
contained in (x) with respect to the Indenture Trustee, the servicing criteria
assessment provided under this Article X and (y) with respect to the Servicer,
Section 3.10 and Section 3.11 of this Agreement by or on behalf of such Person
(with respect to each such party, the "Provided Information"), or (B) the
omission or alleged omission to state in the Provided Information a material
fact required to be stated in the Provided Information, or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided, by way of clarification, that clause (B) of
this paragraph shall be construed solely by reference to the related Provided
Information and not to any other information communicated in connection with a
sale or purchase of securities, without regard to whether the Provided
Information or any portion thereof is presented together with or separately from
such other information; or

      (ii) with respect to the Indenture Trustee, any failure by the Indenture
Trustee to deliver any servicing criteria assessment when and as required under
this Article X and with respect to the Servicer, any failure by the Servicer to
deliver any information, report, certification, accountant's letter or other
material when and as required under Section 3.10, Section 3.11 or Article X, as
applicable.

      (b) In the case of any failure of performance described in clause (ii) of
this Section, each of the Indenture Trustee and the Servicer shall promptly
reimburse the Depositor for all costs reasonably incurred by each such party in
order to obtain the information, report, certification, accountants' letter or
other material not delivered as required by the Indenture Trustee or the
Servicer, as applicable.

      (c) Each of the Indenture Trustee and the Servicer shall require that any
Reporting Subcontractor agree to the provisions of paragraphs (a) and (b) of
this Section 10.9, or shall be responsible for all such indemnification, costs
or expenses if the Reporting Subcontractor will not agree to such provisions.

                                       45
<PAGE>

      (d) Notwithstanding anything to the contrary contained herein, in no event
shall the Indenture Trustee be liable for special, indirect or consequential
damages of any kind whatsoever, including but not limited to lost profits, even
if the Indenture Trustee has been advised of the likelihood of such loss or
damage and regardless of the form of action.

      SECTION 10.10 Amendments. In the event the parties to this Agreement
desire to further clarify or amend any provision of this Article X, this
Agreement shall be amended to reflect the new agreement between the parties
covering matters in this Article X pursuant to Section 9.01, provided such
amendment will not require any Opinion of Counsel or satisfaction of the Rating
Agency Condition or the consent of any Noteholder or Certificateholder.

                                       46

                             DEFINITIONS AND USAGE

      The following rules of construction and usage shall be applicable to any
agreement or instrument that is governed by this Appendix:

when used in any agreement or instrument governed hereby and in any
certificate or other document made or delivered pursuant thereto unless
otherwise defined therein.

in any certificate or other document made or delivered pursuant thereto,
accounting terms not defined in this Appendix or in any such agreement,

in this Appendix or in any such agreement, instrument, certificate or other
document, to the extent not defined, shall have the respective meanings given
to them under generally accepted accounting principles as in effect on the
date of such agreement or instrument. To the extent that the definitions of
accounting terms in this Appendix or in any such agreement, instrument,
certificate or other document are inconsistent with the meanings of such terms
under generally accepted accounting principles, the definitions contained in
this Appendix or in any such instrument, certificate or other document shall
control.

      The words "hereof," "herein," "hereunder" and words of similar import
when used in an agreement or instrument refer to such agreement or instrument

references in an agreement or instrument to "Article," "Section" or another
subdivision or to an attachment are, unless the context otherwise requires, to
an article, section or subdivision of or an attachment to such agreement or
instrument; and the term "including" and its variations shall be deemed to be
followed by "without limitation."

      The definitions contained in this Appendix are equally applicable to
both the singular and plural forms of such terms and to the masculine as well
as to the feminine and neuter genders of such terms.

      Any agreement, instrument or statute defined or referred to below or in
any agreement or instrument that is governed by this Appendix means such
agreement or instrument or statute as from time to time amended, modified or
supplemented, including (in the case of agreements or instruments) by waiver
or consent and (in the case of statutes) by succession of comparable successor
statutes and includes (in the case of agreements or instruments) references to
all attachments thereto and instruments incorporated therein. References to a
Person are also to its permitted successors and assigns.

                               within 30 calendar days of full repayment of the
                               related pool assets, or such other number of days

                               are paid from the Servicer's funds and not
                               charged to the obligor, unless the late payment
1122(d)(4)(xii)                was due to the obligor's error or omission.
----------------------------------------------------------------------------------------------------------------------
                               Disbursements made on behalf of an obligor are

rights have terminated pursuant to Section 2.15 of this Agreement.

               (j) The number of shares of “Registrable Securities then outstanding” shall be
determined by the number of shares of Common Stock outstanding which are, and the number of shares
of Common Stock issuable pursuant to then exercisable or convertible securities which are,
Registrable Securities.

               (k) “SEC” means the Securities and Exchange Commission.

               (l) “Securities Act” means the Securities Act of 1933, as amended, (and any successor

          2.2 Request for Registration.

               (a) If the Company shall receive at any time after the earlier of (i) January 1, 2008, or (ii)
180 days after the effective date of registration statement pertaining to an IPO, a written request
from the Holders of a majority of the Registrable Securities then outstanding, voting together as a
single class on an as-converted to Common Stock basis (the “Initiating Holders”), that the
Company file a registration statement under the Securities Act covering the registration of
Registrable Securities with an anticipated aggregate offering price of at least $25,000,000, then
the Company shall, within 20 days after receiving such request, give written notice of such request
to all Holders and shall, subject to the limitations of subsection 2.2(b), use all commercially
reasonable efforts to cause to be registered under the Securities Act all of the Registrable
Securities that each such Holder has requested to be registered within 20 days after the mailing of
such notice by the Company.

               (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their
request by means of an underwriting, they shall so advise the Company as a part of their request
and the Company shall include such information in the written notice referred to in subsection
2.2(a). The underwriter will be selected by the Company, which underwriter shall be reasonably
acceptable to a majority in interest of the Holders whose Registrable Securities are to be included
in the underwriting. In such event, the right of any
Holder to include Registrable Securities in such registration shall be conditioned upon such

4

 

Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable
Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder) to the extent provided herein. The Company and all Holders
proposing to distribute their securities through such underwriting shall enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for such underwriting.
Notwithstanding any other provision of this Section 2.2, if the underwriter advises the Company in
good faith that marketing factors require a limitation of the number of shares to be underwritten,
then the Company shall so advise all Holders of Registrable Securities which would otherwise be
underwritten pursuant hereto, and the number of shares of Registrable Securities that may be
included in the underwriting shall be allocated among all participating Holders thereof, including
the Initiating Holders, in proportion (as nearly as practicable) to the amount of Registrable
Securities of the Company owned by each participating Holder. In no event shall any Registrable
Securities be excluded from such underwriting unless all other securities are first excluded from
such offering. Any Registrable Securities excluded from or withdrawn from such underwriting shall
be withdrawn from registration.

               (c) Notwithstanding the foregoing, if the Company shall furnish to the Initiating Holders a
certificate signed by the President of the Company stating that in the good faith judgment of the
Board of Directors of the Company (the “Board of Directors”) it would be seriously
detrimental to the Company and its stockholders for such registration statement to be filed, the
Company shall have the right to defer such filing for a period of not more than 120 days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right or the similar right set forth in Section 2.4(b)(iii) more than
once in any 12-month period, and provided, further, that the Company shall not register any
securities for the account of itself or any other stockholder during such 120-day period (other
than in an IPO or an Excluded Registration).

               (d) In addition, the Company shall not be obligated to effect, or to take any action to
effect, any registration pursuant to this Section 2.2:

                    (i) After the Company has effected two (2) registrations pursuant to this Section 2.2 and such
registrations have been declared or ordered effective, provided, however, that such
registrations have been declared or ordered effective and that either (A) the conditions of Section
2.5(a) have been satisfied or (B) the registration statements remain effective and there are no
stop orders in effect to such registration statements;

                    (ii) During the period starting with the date 90 days prior to the Company’s good faith
estimate of the date of filing of, and ending on a date 180 days after the effective date of, a
registration subject to Section 2.3 hereof, unless such offering is not the initial public offering
of the Company’s securities, in which case, ending on a date 90 days after the effective date of
such registration subject to Section 2.3 hereof; provided that the Company is actively employing in
good faith all commercially reasonable efforts to cause such registration statement to become
effective; or

                    (iii) If the Initiating Holders propose to dispose of shares of Registrable Securities that
may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.4 below.

5

 

          2.3 Company Registration.

               (a) If (but without any obligation to do so) at any time after the earlier of (i) January 1,
2008 or (ii) 180 days after the effective date of the registration statement pertaining to an IPO,
the Company proposes to register (including for this purpose a registration effected by the Company
for stockholders other than the Holders) any of its stock under the Securities Act in connection
with the public offering of such securities solely for cash (other than an Excluded Registration or
any registration on any form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within 20 days after mailing of such
notice by the Company in accordance with Section 4.5, the Company shall, subject to the provisions
of Section 2.8, use all commercially reasonable efforts to cause to be registered under the
Securities Act all of the Registrable Securities that each such Holder has requested to be
registered if any stock of the Company is registered.

               (b) The Company shall have the right to terminate or withdraw any registration initiated by it
under this Section 2.3 prior to the effectiveness of such registration whether or not any Holder
has elected to include securities in such registration. The expenses of such registration shall be
borne by the Company, in accordance with Section 2.7 hereof.

          2.4 Form S-3 Registration. In case the Company shall receive from any Holder or
Holders of not less than 30% of the Registrable Securities then outstanding, voting together as a
single class on an as-converted to Common Stock basis, a written request or requests that the
Company effect a registration on Form S-3 with respect to all or a part of the Registrable
Securities owned by such Holder or Holders, the Company will:

               (a) promptly give written notice of the proposed registration, and any related qualification
or compliance, to all other Holders; and

               (b) use all commercially reasonable efforts to effect, as soon as practicable, such
registration and all such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’
Registrable Securities as are specified in such request, together with all or such portion of the
Registrable Securities of any other Holder or Holders joining in such request as are specified in a
written request given within 15 days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 2.4: (i) if Form S-3 is not
available for such offering by the Holders; (ii) if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration, propose to sell
Registrable Securities and such other securities (if any) at an aggregate price to the public of
less than $1,000,000; (iii) if the Company shall furnish to the Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of Directors, it
would be seriously detrimental to the Company and its stockholders for such registration statement
to be filed, in the Company shall have the right to defer such filing for a period of not more than
120 days after receipt of the request of the Holder or Holders under this Section 2.4;
provided, however, that the Company shall not utilize this right or the similar
right set forth in

6

 

Section 2.2(c) more than once in any 12-month period; (iv) if the Company has,
within the 12-month period preceding the date of such request, already effected two registrations
on Form S-3 for the Holders pursuant to this Section 2.4; (v) in any jurisdiction in which the
Company would be required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance unless the Company is already
qualified to do business or subject to service of process in that jurisdiction; or (vi) during the
period ending 180 days after the effective date of a registration statement subject to Section 2.3.

               (c) Subject to the foregoing, the Company shall file a registration statement covering the
Registrable Securities and other securities so requested to be registered as soon as practicable
after receipt of the request or requests of the Holders. Registrations effected pursuant to this
Section 2.4 shall not be counted as demands for registration or registrations effected pursuant to
Sections 2.2 or 2.3, respectively.

          2.5 Obligations of the Company. Whenever required under this Section 2 to effect the
registration of any Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

               (a) Prepare and file with the SEC a registration statement with respect to such Registrable
Securities and use all commercially reasonable efforts to cause such registration statement to
become effective, and, upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for up to 120 days, or until the
distribution described in such registration statement is completed, if earlier.

               (b) Prepare and file with the SEC such amendments and supplements to such registration
statement and the prospectus used in connection with such registration statement as may be
necessary to comply with the provisions of the Securities Act with respect to the disposition of
all securities covered by such registration statement for up to 120 days, or until the distribution
described in such registration statement is completed, if earlier.

               (c) Promptly notify the Holders of the effectiveness of such registration statement, and
furnish to the Holders such numbers of copies of a prospectus, including any supplement to the
prospectus, in conformity with the requirements of the Securities Act, and such other documents as
they may reasonably request in order to facilitate the disposition of Registrable Securities owned
by them.

               (d) Following the effective date of such registration statement, notify the Holders of any
request by the SEC that the Company amend or supplement such registration statement, or the
associated prospectus.

               (e) Use all commercially reasonable efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such jurisdictions as
shall be reasonably requested by the Holders, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdiction unless the Company is
already qualified to do business or subject to service of process in that jurisdiction.

7

 

               (f) In the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement, in usual and customary form, with the managing underwriter of such
offering. Each Holder and other security holder participating in such underwriting shall also
enter into and perform its obligations under such an agreement.

               (g) Notify each Holder of Registrable Securities covered by such registration statement at any
time when a prospectus relating thereto is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such registration statement,
as then in effect, includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing, such obligation to continue for 120 days or until the
distribution described in such registration statement is completed, if earlier.

               (h) Cause all such Registrable Securities registered pursuant to this Section 2 to be listed
on each national securities exchange or trading system on which similar securities issued by the
Company are then listed.

               (i) Provide a transfer agent and registrar for all Registrable Securities registered pursuant
hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the
effective date of such registration.

               (j) Make generally available to its security holders, and to deliver to each Holder
participating in the registration statement, an earnings statement of the Company that will satisfy
the provisions of Section 11(a) of the Securities Act covering a period of 12 months beginning
after the effective date of such registration statement as soon as reasonably practicable after the
termination of such 12-month period.

          2.6 Information From Holders. It shall be a condition precedent to the obligations of
the Company to take any action pursuant to this Section 2 with respect to the Registrable
Securities of any selling Holder that such Holder shall furnish to the Company such information
regarding such Holder, the Registrable Securities held by it, and the intended method of
disposition of such securities as shall be required to effect the registration of such Holder’s
Registrable Securities. The Company shall have no obligation with respect to any registration
requested pursuant to Section 2.2 or Section 2.4 of this Agreement if, as a result of the
application of the preceding sentence, or the anticipated aggregate offering price of the
Registrable Securities to be included in the registration does not equal or exceed the anticipated
aggregate offering price required to originally trigger the Company’s obligation to initiate such
registration as specified in subsection 2.2(a) or subsection 2.4(b)(ii), whichever is applicable.

          2.7 Expenses of Registration. All expenses other than underwriting discounts and
commissions incurred in connection with registrations, filings or qualifications pursuant to
Sections 2.2, 2.3 and 2.4 including (without limitation) all registration, filing and qualification
fees, printers’ and accounting fees, fees and disbursements of counsel for the Company, and the
reasonable fees and disbursements of one counsel for the selling Holders selected by them with the
approval of the Company, which approval shall not be unreasonably withheld, shall be borne by the
Company; provided, however, that the Company shall not be required to pay for any

8

 

expenses of any registration proceeding begun pursuant to Section 2.2 or 2.4 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of the Registrable
Securities to be registered (in which case all participating Holders shall bear such expenses),
unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one
demand registration pursuant to Section 2.2 or one right to a Form S-3 registration under Section
2.4, as the case may be.

          2.8 Underwriting Requirements. In connection with any offering involving an
underwriting of shares of the Company’s capital stock, the Company shall not be required under
Section 2.3 to include any of the Holders’ securities in such underwriting unless they accept the
terms of the underwriting as agreed upon between the Company and the underwriters selected by the
Company (or by other persons entitled to select the underwriters), and then only in such quantity
as the underwriters determine in their sole discretion will not jeopardize the success of the
offering by the Company. If the total amount of securities, including Registrable Securities,
requested by stockholders to be included in such offering exceeds the amount of securities sold
other than by the Company that the underwriters determine in their sole discretion is compatible
with the success of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which the underwriters
determine in their sole discretion will not jeopardize the success of the offering (the securities
so included to be apportioned pro rata among the selling stockholders according to the total amount
of securities entitled to be included therein owned by each selling stockholder or in such other
proportions as shall mutually be agreed to by such selling stockholders). For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder which is a holder of
Registrable Securities and which is a venture capital fund, or a partnership or corporation, the
Affiliated Funds, members, partners, retired partners and stockholders of such holder, or the
estates and family members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons shall be deemed to be a single “selling stockholder,” and
any pro-rata reduction with respect to such “selling stockholder” shall be based upon the aggregate
amount of shares carrying registration rights owned by all entities and individuals included in
such “selling stockholder,” as defined in this sentence.

          2.9 Delay of Registration. No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any such registration as the result of any controversy
that might arise with respect to the interpretation or implementation of this Section 2.

          2.10 Indemnification. In the event any Registrable Securities are included in a
registration statement under this Section 2:

               (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder,
any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who
controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities (joint or several) to which they may become
subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based
upon any of the following statements, omissions or violations (collectively a “Violation”):
(i) any untrue statement or alleged untrue statement of a material

9

 

fact contained in such
registration statement, including any preliminary prospectus or final prospectus contained therein
or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements therein not
misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities law or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any state securities law; and the Company will pay to each such Holder,
underwriter or controlling person, as incurred, any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
subsection 2.10(a) shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability, or action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld), nor shall the Company be liable to any Holder,
underwriter or controlling person for any such loss, claim, damage, liability, or action to the
extent that it arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

               (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the
Company, each of its directors, each of its officers who has signed the registration statement,
each person, if any, who controls the Company within the meaning of the Securities Act, any
underwriter, any other Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject, under the Securities
Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each
case to the extent (and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder expressly for use in connection with
such registration; and each such Holder will pay, as incurred, any legal or other expenses
reasonably incurred by any person intended to be indemnified pursuant to this subsection 2.10(b),
in connection with investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.10(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Holder, which consent shall not be
unreasonably withheld; provided, that in no event shall any indemnity under this subsection
2.10(b) exceed the net proceeds from the offering received by such Holder, except in the case of
willful fraud by such Holder.

               (c) Promptly after receipt by an indemnified party under this Section 2.10 of notice of the
commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against any
indemnifying party under this Section 2.10, deliver to the indemnifying party a written notice of
the commencement thereof and the indemnifying party shall have the right to participate in, and, to
the extent the indemnifying party so desires, jointly with any other indemnifying party similarly
noticed, to assume the defense thereof with counsel mutually satisfactory to the parties;
provided, however, that an indemnified party (together with all other indemnified
parties which may be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with the reasonable fees and expenses to be paid by the indemnifying party,
if

10

 

representation of such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential differing interests between such indemnified party and
any other party represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of any such action,
if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this Section 2.10, but the omission so to deliver written
notice to the indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 2.10.

               (d) If the indemnification provided for in this Section 2.10 is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim,
damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions that resulted in such
loss, liability, claim, damage or expense as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by a Holder under this Subsection 2.10(d)
exceed the net proceeds from the offering received by such Holder, except in the case of willful
fraud by such Holder. The relative fault of the indemnifying party and of the indemnified party
shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a material fact relates
to information supplied by the indemnifying party or by the indemnified party and the parties’
relative intent, knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

               (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and
contribution contained in the underwriting agreement entered into in connection with the
underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.

               (f) The obligations of the Company and Holders under this Section 2.10 shall survive the
completion of any offering of Registrable Securities in a registration statement under this Section
2, and otherwise.

          2.11 Reports Under the Exchange Act. With a view to making available to the Holders
the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of
the SEC that may at any
time permit a Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to:

               (a) make and keep public information available, as those terms are understood and defined in
SEC Rule 144, at all times after 90 days after the effective date of an IPO so long as the Company
remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange
Act;

               (b) take such action, including the voluntary registration of its Common Stock under Section
12 of the Exchange Act, as is necessary to enable the Holders to

11

 

utilize Form S-3 for the sale of
their Registrable Securities, such action to be taken as soon as practicable after the end of the
fiscal year in which the first registration statement filed by the Company for the offering of its
securities to the general public is declared effective;

               (c) file with the SEC in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act; and

               (d) furnish to any Holder upon request, so long as the Holder owns any Registrable Securities,
(i) a written statement by the Company that it has complied with the reporting requirements of SEC
Rule 144 (at any time after 90 days after the effective date of an IPO), the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting requirements), or that
it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after
it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such
other reports and documents so filed by the Company, and (iii) such other information as may be
reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

          2.12 Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities pursuant to this Section 2 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee (a) of at least 25,000 shares of such
securities (subject to adjustment for stock splits, stock dividends, reclassification or the like
with respect to such shares) (or if the transferring Holder owns less than 25,000 shares of such
securities, then all Registrable Securities held by the transferring Holder), (b) that is a
subsidiary, parent, partner, limited partner, retired partner, member, retired member or
stockholder of a Holder, (c) that is an Affiliated Fund, (d) who is a Holder’s child, stepchild,
grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law,
son-in-law, daughter-in-law, brother-in-law, or sister-in-law (such a relation, a Holder’s
“Immediate Family Member”, which term shall include adoptive relationships), or (e) that is
a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member,
provided the Company is, within a reasonable time after such transfer, furnished with
written notice of the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; and provided,
further, that such assignment shall be effective only if the transferee agrees in writing
to be bound by this Agreement and immediately following such transfer the further disposition of
such securities by the transferee or assignee is restricted under the Securities Act. For the
purposes of determining the number of shares of Registrable Securities held by a transferee or
assignee, the holdings of transferees and assignees of (x) a partnership who are partners or
retired partners of such partnership or (y) a limited liability company who are members or retired
members of such limited liability company (including Immediate Family Members of such partners or
members who acquire Registrable Securities by gift, will or intestate succession) shall be
aggregated together and with the partnership or limited liability company; provided that all
assignees and transferees who would not qualify individually for assignment of registration rights
shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or
taking any action under Section 2.

          2.13 Limitations on Subsequent Registration Rights. From and after the date of this
Agreement, the Company shall not, without the prior written consent of the Holders

12

 

of a majority of
the outstanding Registrable Securities, enter into any agreement with any holder or prospective
holder of any securities of the Company which would allow such holder or prospective holder (a) to
include any of such securities in any registration filed under Section 2.2 hereof, unless under the
terms of such agreement, such holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of his securities will not reduce the amount of
the Registrable Securities of the Holders which is included or (b) to make a demand registration
which could result in such registration statement being declared effective prior to the earlier of
either of the dates set forth in subsection 2.2(a) or within 120 days of the effective date of any
registration effected pursuant to Section 2.2.

          2.14 Lock-Up Agreement.

               (a) Lock-Up Period; Agreement. In connection with the initial public offering of the
Company’s securities and upon request of the Company or the underwriters managing such offering of
the Company’s securities, each Holder shall not sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any securities of the Company, however or
whenever acquired (other than those included in the registration) without the prior written consent
of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180
days, but subject to such extension or extensions as may be required by the underwriters in order
to publish research reports while complying with the Rule 2711 of the National Association of
Securities Dealers, Inc.) from the effective date of such registration as may be requested by the
Company or such managing underwriters, and shall execute an agreement reflecting the foregoing as
may be requested by the underwriters at the time of the Company’s initial public offering.

               (b) Limitations. The obligations described in Section 2.14(a) shall apply only if all
officers and directors of the Company and all greater than 5% stockholders enter into similar
agreements, and shall not apply to a registration relating solely to employee benefit plans, or to
a registration relating solely to a transaction pursuant to Rule 145 under the Securities Act.

               (c) Stop-Transfer Instructions. In order to enforce the foregoing covenants, the
Company may impose stop-transfer instructions with respect to the securities of each Holder (and
the securities of every other person subject to the restrictions in Section 2.14(a)).

               (d) Transferees Bound. Each Holder agrees that prior to the Company’s initial public
offering it will not transfer securities of the Company unless each transferee agrees in writing to
be bound by all of the provisions of this Section 2.14.

               (e) Each Holder agrees that a legend reading substantially as follows shall be placed on all
certificates representing all Registrable Securities of each Holder (and the shares or securities
of every other person subject to the restriction contained in this Section 2.14):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD
OF UP TO 180 DAYS AFTER THE EFFECTIVE DATE OF THE ISSUER’S REGISTRATION
STATEMENT

13

 

FILED UNDER THE ACT, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN
THE COMPANY AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE
OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD IS BINDING ON
TRANSFEREES OF THESE SHARES.

          2.15 Termination of Registration Rights. No Holder shall be entitled to exercise any
right provided for in this Section 2 after the earlier of (a) five (5) years following the
consummation of an IPO, (b) with respect to any Holder, at such time after the IPO as Rule 144 or
another similar exemption under the Securities Act is available for the sale of all of such
Holder’s shares during a three-month period without registration, or (c) upon termination of the
Agreement, as provided in Section 4.2.

     3. Covenants of the Company.

          3.1 Delivery of Financial Statements. The Company shall deliver to each Major
Investor (other than a Major Investor reasonably deemed by the Company to be a competitor of the
Company):

               (a) as soon as practicable, but in any event within 120 days after the end of each fiscal year
of the Company (or such longer period of time as may be required by the Company’s independent
public accountants), an income statement for such fiscal year, a balance sheet of the Company and
statement of stockholder’s equity as of the end of such year, and a statement of cash flows for
such year, such year-end financial reports to be in reasonable detail, prepared in accordance with
U.S. generally accepted accounting principles (“GAAP”), and audited and certified by an
independent public accounting firm of nationally recognized standing selected by the Company;

               (b) as soon as practicable, but in any event within 45 days after the end of each of the first
three quarters of each fiscal year of the Company, an unaudited profit or loss statement, a
statement of cash flows for such fiscal quarter and an unaudited balance sheet as of the end of
such fiscal quarter;

               (c) within 30 days of the end of each month, an unaudited income statement and a statement of
cash flows and balance sheet for and as of the end of such month, in reasonable detail;

               (d) as soon as practicable, but in any event prior to the end of each fiscal year, a budget
and business plan for the next fiscal year, prepared on a monthly basis, and, as soon as prepared,
any other updated or revised budgets for such fiscal year prepared by the Company; and

               (e) with respect to the financial statements called for in subsections (b) and (c) of this
Section 3.1, an instrument executed by the Chief Financial Officer or President of the Company and
certifying on behalf of the Company that such financials were prepared in accordance with GAAP
consistently applied with prior practice for earlier periods (with the exception of footnotes that
may be required by GAAP) and fairly present the financial condition

14

 

of the Company and its results
of operation for the period specified, subject to year-end audit adjustment, provided that the
foregoing shall not restrict the right of the Company to change its accounting principles
consistent with GAAP, if the Board of Directors or a committee thereof determines that it is in the
best interest of the Company to do so.

          3.2 Inspection. The Company shall permit each Major Investor (except for a Major
Investor reasonably deemed by the Company to be a competitor of the Company), at such Major
Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account
and records and to discuss the Company’s affairs, finances and accounts with its officers, all at
such reasonable times as may be requested by the Major Investor; provided, however,
that the Company shall not be obligated pursuant to this Section 3.2 to provide access to any
information which it reasonably considers to be a trade secret or similar confidential information.

          3.3 Termination of Covenants. The covenants set forth in Sections 3.1 and 3.2 shall
terminate as to each Holder and be of no further force or effect (a) immediately prior to the
consummation of an IPO, (b) when the Company first becomes subject to the periodic reporting
requirements of Sections 13 or 15(d) of the Exchange Act or (c) upon termination of this Agreement,
as provided in Section 4.2, whichever is the earliest to occur.

     4. Miscellaneous.

          4.1 Waiver of Registration Rights. Effective and contingent upon execution of this
Agreement by the Company and the holders of at least a majority of the “Registrable Securities,” as
that term is defined in each of the Prior Agreements, any and all rights of the holders of
Registrable Securities under the Prior Agreements to register and sell their Registrable Securities
or any other securities of the Company held by such holders as part of or in connection with the
proposed initial public offering of the Company’s Common Stock pursuant to that certain
Registration Statement on Form S-1 (File No. 333-134086), filed with the Securities and Exchange
Commission on May 12, 2006, are hereby waived.

          4.2 Termination. This Agreement shall terminate, and have no further force and
effect, (a) upon the closing of a Sale of the Company (as defined below) or (b) upon the written
agreement of the Company and the holders of a majority of the Registrable Securities then
outstanding, voting together as a single class on an as-converted to Common Stock basis. For
purposes of this Section 4.2, a “Sale of the Company” shall include a sale, lease, or other
disposition of all or substantially all of the Company’s assets or business or the Company’s merger
into or consolidation with any other corporation or other entity, or any other corporate
reorganization, in which the holders of the Company’s outstanding voting stock immediately prior to
such transaction own, immediately after such transaction, securities representing less than fifty
percent (50%) of the voting power of the corporation or other entity surviving such transaction,
provided that a Sale of the Company shall not include a merger effected exclusively for the purpose
of changing the domicile of the Company or a sale of shares by the Company for primarily equity
financing purposes.

          4.3 Entire Agreement. This Agreement constitutes the entire agreement between the
parties hereto pertaining to the subject matter hereof, and any and all other written

15

 

or oral
agreements relating to the subject matter hereof existing between the parties hereto, including
without limitation, the Prior Agreements, are expressly terminated and canceled.

          4.4 Successors and Assigns. Except as otherwise provided in this Agreement, the terms
and conditions of this Agreement shall inure to the benefit of and be binding upon the respective
permitted successors and assigns of the parties (including transferees of any Preferred Stock or
any Common Stock issued upon conversion thereof). Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto or their respective successors
and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

          4.5 Amendments and Waivers. Any term of this Agreement may be amended or waived only
with the written consent of the Company and the Investors holding a majority of the Registrable
Securities then outstanding. Notwithstanding the foregoing, this Agreement may be amended with
only the written consent of the Company for the sole purpose of including additional purchasers of
Preferred Stock as “Investors” and “Holders.” Any amendment or waiver effected in accordance with
this paragraph shall be binding upon each party to the Agreement, whether or not such party has
signed such amendment or waiver, each future holder of all such Registrable Securities, and the
Company.

          4.6 Notices. Unless otherwise provided, any notice required or permitted by this
Agreement shall be in writing and shall be deemed sufficient upon delivery, when delivered
personally or by overnight courier or sent by facsimile, or 48 hours after being deposited in the
U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be
notified at such party’s address or facsimile number as set forth on Exhibit A hereto or as
subsequently modified by written notice.

          4.7 Severability. If one or more provisions of this Agreement are held to be
unenforceable under applicable law, such provision shall be excluded from this Agreement, and the
balance of the Agreement shall be interpreted as if such provision were so excluded and shall be
enforceable in accordance with its terms.

          4.8 Governing Law. This Agreement and all acts and transactions pursuant hereto shall
be governed, construed and interpreted in accordance with the laws of the State of California,
without giving effect to principles of conflicts of laws.

          4.9 Counterparts. This Agreement may be executed in two or more counterparts,
including facsimiles, each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

          4.10 Titles and Subtitles. The titles and subtitles used in this Agreement are used
for convenience only and are not to be considered in construing or interpreting this Agreement.

          4.11 Aggregation of Stock. All shares of the Preferred Stock held or acquired by
affiliated entities or persons shall be aggregated together for the purpose of determining the
availability of any rights under this Agreement.
