SECTION 3.2. The Certificate. The Certificate shall be executed on behalf of the Trust by manual or facsimile signature of an authorized officer of the Owner Trustee. A Certificate bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have

been affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to the benefit of this Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the authentication and delivery of such Certificate or did not hold such offices at the date of authentication and delivery of such Certificate. A transferee of a Certificate shall become a Certificateholder, and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder, upon due registration of such Certificate in such transferee's name pursuant to Section 3.4.

SECTION 3.3. Authentication of Certificate. Concurrently with the sale of the Receivables to the Trust pursuant to the Sale and Servicing Agreement, the Owner Trustee shall cause the Certificate to be executed on behalf of the Trust, authenticated and delivered to or upon the written order of the Depositor, signed by its chairman of the board, its president or any vice president, its treasurer or any assistant treasurer without further corporate action by the Depositor, in authorized denominations. No Certificate shall entitle its holder to any benefit under this Agreement, or shall be valid for any purpose, unless there shall appear on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A, executed by the Owner Trustee or Deutsche Bank Trust Company Americas as the Owner Trustee's authentication agent, by manual signature; such authentication shall constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. The Certificate shall be dated the date of its authentication.

SECTION 3.4. Registration of Transfer and Exchange of Certificate. The Certificate Registrar shall keep or cause to be kept, at the office or agency maintained pursuant to Section 3.7, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Owner Trustee shall provide for the registration of the Certificate and of transfers and exchanges of the Certificate as herein provided. Deutsche Bank Trust Company Americas shall be the initial Certificate Registrar.

The Certificate Registrar shall provide the Trust Collateral Agent with the name and address of the Certificateholder on the Closing Date. Upon any transfers of the Certificate, the Certificate Registrar shall notify the Trust Collateral Agent of the name and address of the transferee in writing, by facsimile, on the day of such transfer.

Upon surrender for registration of transfer of the Certificate at the office or agency maintained pursuant to Section 3.7, the Owner Trustee shall execute, authenticate and deliver (or shall cause Deutsche Bank Trust Company Americas as its authenticating agent to authenticate and deliver), in the name of the designated transferee, a new Certificate dated the date of authentication by the Owner Trustee or any authenticating agent.

A Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Owner Trustee and the Certificate Registrar duly executed by the Certificateholder or his attorney duly authorized in writing, with such signature guaranteed by an "eligible guarantor institution" meeting the requirements of the Certificate Registrar, which requirements include membership or participation in the Securities Transfer Agent's Medallion Program ("STAMP") or such other "signature guarantee program" as may be determined by the Certificate Registrar in addition to, or in substitution for, STAMP, all in accordance with the Exchange Act. Each Certificate surrendered for registration of transfer or exchange shall be canceled and subsequently disposed of by the Owner Trustee in accordance with its customary practice.

No service charge shall be made for any registration of transfer or exchange of the Certificate, but the Owner Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of the Certificate.

SECTION 3.5. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate shall be surrendered to the Certificate Registrar, or if the Certificate Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there shall be delivered to the

Certificate Registrar, the Owner Trustee and (unless an Insurer Default shall have occurred and be continuing) the Security Insurer, such security or indemnity as may be required by them to save each of them harmless, then in the absence of notice that such Certificate shall have been acquired by a bona fide purchaser, the Owner Trustee on behalf of the Trust shall execute and the Owner Trustee, or Deutsche Bank Trust Company Americas, as the Owner Trustee's authenticating agent, shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like class, tenor and denomination. In connection with the issuance of any new Certificate under this Section, the Owner Trustee or the Certificate Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Certificate issued pursuant to this Section shall constitute conclusive evidence of an ownership interest in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

SECTION 3.6. Persons Deemed Certificateholders. Every Person by virtue of becoming a Certificateholder in accordance with this Agreement shall be deemed to be bound by the terms of this Agreement. Prior to due presentation of the Certificate for registration of transfer, the Owner Trustee, the Certificate Registrar and the Security Insurer and any agent of the Owner Trustee, the Certificate Registrar and the Security Insurer, may treat the person in whose name any Certificate shall be registered in the Certificate Register as the owner of such Certificate for the purpose of receiving distributions pursuant to the Sale and Servicing Agreement and for all other purposes whatsoever, and none of the Owner Trustee, the Certificate Registrar or the Security Insurer nor any agent of the Owner Trustee, the Certificate Registrar or the Security Insurer shall be bound by any notice to the contrary.

SECTION 3.7. Maintenance of Office or Agency. The Owner Trustee shall maintain in New York, an office or offices or agency or agencies where the Certificate may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Owner Trustee in respect of the Certificate and the Basic Documents may be served.

The Owner Trustee shall give prompt written notice to the Depositor, the Certificateholder and (unless an Insurer Default shall have occurred and be continuing) the Security Insurer of any change in the location of the Certificate Register or any such office or agency.

SECTION 3.8. Disposition in Whole But Not in Part. The Certificate may be transferred in whole but not in part. Any attempted transfer of the Certificate that would divide the ownership of the Owner Trust Estate shall be void. The Certificate is only transferable (i) to an Affiliate of AmeriCredit Corp. whose stock has been pledged to the Security Insurer or (ii) to another entity with the prior written consent of the Security Insurer in its sole discretion. The Owner Trustee shall cause any Certificate issued to contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE, EXCEPT UNDER THE LIMITED CONDITIONS SPECIFIED IN THE TRUST AGREEMENT."

SECTION 3.9. ERISA Restrictions. The Certificate may not be acquired by or for the account of (i) an employee benefit plan (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) that is subject to the provisions of Title I of ERISA, (ii) a plan (as defined in Section 4975(e)(1) of the Code) that is subject to Section 4975 of the Code, or (iii) any entity whose underlying assets include assets of a plan described in (i) or (ii) above by reason of such plan's investment in the entity (each, a "Benefit Plan"). By accepting and holding its beneficial ownership interest in its Certificate, the Holder thereof shall be deemed to have represented and warranted that it is not a Benefit Plan.

SECTON 4.2. Action by Certificateholder with Respect to Certain Matters. The Owner Trustee shall not have the power, except upon the direction of the Certificateholder or the Security Insurer in accordance with the Basic Documents, to (a) remove the Servicer under the Sale and Servicing Agreement pursuant to Section 9.2 thereof or (b) except as expressly provided in the Basic Documents, sell the Receivables after the termination of the Indenture.

SECTION 4.3. Restrictions on Certificateholder's Power.

(a) The Certificateholder shall not direct the Owner Trustee to take or refrain from taking any action if such action or inaction would be contrary to any obligation of the Trust or the Owner Trustee under this Agreement or any of the Basic Documents or would be contrary to Section 2.3 nor shall the Owner Trustee be obligated to follow any such direction, if given.

(b) The Certificateholder shall not have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action, or proceeding in equity or at law upon or under or with respect to this Agreement or any Basic Document, unless the Certificateholder is the Instructing Party pursuant to Section 5.3 and unless the Certificateholder previously shall have given to the Owner Trustee a written notice of default and of the continuance thereof, as provided in this Agreement, and also unless Certificateholder shall have made written request upon the Owner Trustee to institute such action, suit or proceeding in its own name as Owner Trustee under this Agreement and shall have offered to the Owner Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Owner Trustee, for 30 days after its receipt of such notice, request, and offer of indemnity, shall have neglected or refused to institute any such action, suit, or proceeding, and during such 30-day

The Owner Trustee shall have no duty to give such written consent to Bankruptcy Action by the Trust if the Owner Trustee shall not have been furnished (at the expense of the Trust) or the Person that requested that such letter be furnished to the Owner Trustee) a letter from an independent accounting firm of national reputation stating that in the opinion of such firm the Trust is then insolvent. The Owner Trustee (as such and in its individual capacity) shall not be personally liable to any Person on account of the Owner Trustee's good faith reliance on the provisions of this Section or in connection with the Owner Trustee's giving prior written consent to Bankruptcy Action by the Trust in accordance herewith, or withholding such consent, in good faith, and neither the Trust nor any Certificateholder shall have any claim for breach of fiduciary duty or otherwise against the Owner Trustee (as such and in its individual capacity) for giving or withholding its consent to any such Bankruptcy Action.

(b) The parties hereto stipulate and agree that no Certificateholder has power to commence any Bankruptcy Action on the part of the Trust or to direct the Owner Trustee to take any Bankruptcy Action on the part of the Trust. To the extent permitted by applicable law, the consent of the Security Insurer and the Trust Collateral Agent shall be obtained prior to taking any Bankruptcy Action by the Trust.

(c) The provisions of this Section do not constitute an acknowledgement or admission by the Trust, the Owner Trustee, any Certificateholder or any creditor of the Trust that the Trust is eligible to be a debtor, under the United States Bankruptcy Code, I1 U.S.C. §§ 101 et seq., as amended.

SECTION 5.2. General Duties. It shall be the duty of the Owner Trustee to discharge (or cause to be discharged) all of its responsibilities pursuant to the terms of this Agreement and the Sale and Servicing Agreement and to administer the Trust in the interest of the Holder, subject to the Basic Documents and in accordance with the provisions of this Agreement. Notwithstanding the foregoing, the Owner Trustee shall be deemed to have discharged its duties and responsibilities hereunder and under the Basic Documents to the extent the Servicer has agreed in the Sale and Servicing Agreement to perform any act or to discharge any duty of the Trust or the Owner Trustee hereunder or under any Basic Document, and the Owner Trustee shall not be liable for the default or failure of the Servicer to carry out its obligations under the Sale and Servicing Agreement.

The Instructing Party shall not instruct the Owner Trustee in a manner inconsistent with this Agreement or the Basic Documents.

(b) The Owner Trustee shall not be required to take any action hereunder or under any Basic Document if the Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the Owner Trustee or is contrary to the terms hereof or of any Basic Document or is otherwise contrary to law.

(c) Whenever the Owner Trustee is unable to decide between alternative courses of action permitted or required by the terms of this Agreement or any Basic Document, the Owner Trustee shall promptly give notice (in such form as shall be appropriate under the circumstances) to the Instructing Party requesting instruction as to the course of action to be adopted, and to the extent the Owner Trustee acts in good faith in accordance with any written instruction of the Instructing Party received, the Owner Trustee shall not be liable on account of such action to any Person. If the Owner Trustee shall not have received appropriate instruction within ten days of such notice (or within such shorter period of time as reasonably may be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action, not inconsistent with this Agreement or the Basic Documents, as it shall deem to be in the best interests of the Certificateholder, and shall have no liability to any Person for such action or inaction.

(d) In the event that the Owner Trustee is unsure as to the application of any provision of this Agreement or any Basic Document or any such provision is ambiguous as to its application, or is, or appears to be, in conflict with any other applicable provision, or in the event that this Agreement permits any determination by the Owner Trustee or is silent or is incomplete as to the course of action that the Owner Trustee is required to take with respect to a particular set of facts, the Owner Trustee may give notice (in such form as shall be appropriate under the circumstances) to the Instructing Party requesting instruction and, to the extent that the Owner Trustee acts or refrains from acting in good faith in accordance with any such instruction received, the Owner Trustee shall not be liable, on account of such action or inaction, to any Person. If the Owner Trustee shall not have received appropriate instruction within 10 days of such notice (or within such shorter period of time as reasonably may be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action, not inconsistent with this Agreement or the Basic Documents, as it shall deem to be in the best interests of the Certificateholder, and shall have no liability to any Person for such action or inaction.

SECTION 5.4. No Duties Except as Specified in this Agreement or in Instructions. The Owner Trustee shall not have any duty or obligation to manage, make any payment with respect to, register, record, sell, dispose of, or otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from taking any action under, or in connection with, any document contemplated hereby to which the Owner Trustee is a party, except as expressly provided by the terms of this Agreement or in any document or written instruction received by the Owner Trustee pursuant to Section 5.3; and no implied duties or obligations shall be read into this Agreement or any Basic Document against the Owner Trustee.

If such corporation shall publish reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purpose of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of this Section, the Owner Trustee shall resign immediately in the manner and with the effect specified in Section 9.2.

SECTION 9.2. Resignation or Removal of Owner Trustee. The Owner Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the Depositor, the Security Insurer and the Servicer. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor Owner Trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Owner Trustee and one copy to the

successor Owner Trustee, provided that the Depositor shall have received written confirmation from each of the Rating Agencies that the proposed appointment will not result in an increased capital charge to the Security Insurer by either of the Rating Agencies. If no successor Owner Trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Owner Trustee or the Security Insurer may petition any court of competent jurisdiction for the appointment of a successor Owner Trustee.

If at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of Section 9.1 and shall fail to resign after written request therefor by the Depositor, or if at any time the Owner Trustee shall be legally unable to act, or shall be adjudged bankrupt or insolvent, or a receiver of the Owner Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Owner Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor with the consent of the Security Insurer (so long as an Insurer Default shall not have occurred and be continuing) may remove the Owner Trustee. If the Depositor shall remove the Owner Trustee under the authority of the immediately preceding sentence, the Depositor shall promptly appoint a successor Owner Trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the outgoing Owner Trustee so removed, one copy to the Security Insurer and one copy to the successor Owner Trustee and payment of all fees owed to the outgoing Owner Trustee.

Any resignation or removal of the Owner Trustee and appointment of a successor Owner Trustee pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor Owner Trustee pursuant to Section 9.3 and payment of all fees and expenses owed to the outgoing Owner Trustee. The Depositor shall provide notice of such resignation or removal of the Owner Trustee to each of the Rating Agencies.

SECTION 9.3. Successor Owner Trustee. Any successor Owner Trustee appointed pursuant to Section 9.2 shall execute, acknowledge and deliver to the Depositor, the Servicer, the Security Insurer and to its predecessor Owner Trustee an instrument accepting such appointment under this Agreement, and thereupon the resignation or removal of the predecessor Owner Trustee shall become effective and such successor Owner Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor under this Agreement, with like effect as if originally named as Owner Trustee. The predecessor Owner Trustee shall upon payment of its fees and expenses deliver to the successor Owner Trustee all documents and statements and monies held by it under this Agreement; and the Depositor and the predecessor Owner Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor Owner Trustee all such rights, powers, duties and obligations.

No successor Owner Trustee shall accept appointment as provided in this Section unless at the time of such acceptance such successor Owner Trustee shall be eligible pursuant to Section 9.1.

Upon acceptance of appointment by a successor Owner Trustee pursuant to this Section, the Servicer shall mail notice of the successor of such Owner Trustee to the Certificateholder, the Trustee, the Noteholders, the Security Insurer and the Rating Agencies. If the Servicer shall fail to mail such notice within 10 days after acceptance of appointment by the successor Owner Trustee, the successor Owner Trustee shall cause such notice to be mailed at the expense of the Servicer.

SECTION 9.4. Merger or Consolidation of Owner Trustee. Any corporation into which the Owner Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Owner Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Owner Trustee, shall be the successor of the Owner Trustee hereunder, provided such corporation shall be eligible pursuant to Section 9.1, without the execution or filing of any instrument or any further act on the part

of any of the parties hereto, anything herein to the contrary notwithstanding; provided, further, that the Owner Trustee shall mail notice of such merger or consolidation to the Rating Agencies and the Security Insurer.

SECTION 9.5. Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Owner Trust Estate or any Financed Vehicle may at the time be located, the Servicer and the Owner Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Owner Trustee and the Security Insurer to act as co-trustee, jointly with the Owner Trustee, or separate trustee or separate trustees, of all or any part of the Owner Trust Estate, and to vest in such Person, in such capacity, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Servicer and the Owner Trustee may consider necessary or desirable. If the Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request so to do, the Owner Trustee subject, unless an Insurer Default shall have occurred and be continuing, to the approval of the Security Insurer (which approval shall not be unreasonably withheld) shall have the power to make such appointment. No co-trustee or separate trustee under this Agreement shall be required to meet the terms of eligibility as a successor trustee pursuant to Section 9.1 and no notice of the appointment of any co-trustee or separate trustee shall be required pursuant to Section 9.3.

Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) all rights, powers, duties and obligations conferred or imposed upon the Owner Trustee shall be conferred upon and exercised or performed by the Owner Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Owner Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed, the Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Owner Trustee;

(ii) no trustee under this Agreement shall be personally liable by reason of any act or omission of any other trustee under this Agreement; and

(iii) the Servicer and the Owner Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee.

Any notice, request or other writing given to the Owner Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Owner Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Owner Trustee. Each such instrument shall be filed with the Owner Trustee and a copy thereof given to the Servicer and the Security Insurer.

Any separate trustee or co-trustee may at any time appoint the Owner Trustee, its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or

co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Owner Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

SECTION 10.2. No Legal Title to Owner Trust Estate in Certificateholder. The Certificateholder shall not have legal title to any part of the Owner Trust Estate. The Certificateholder shall be entitled to receive distributions in accordance with Article VIII.

THIS CERTIFIES THAT AFS SenSub Corp. is the registered owner of a nonassessable, fully-paid, beneficial ownership interest in certain distributions of AmeriCredit Automobile Receivables Trust 2003-B-X (the "Trust") formed by AFS SenSub Corp., a Nevada corporation (the "Seller").

OWNER TRUSTEE'S CERTIFICATE OF AUTHENTICATION

This is the Certificate referred to in the within-mentioned Trust Agreement.

The Trust was created pursuant to a Trust Agreement dated as of May 2, 2003, as amended and restated as of May 14, 2003 (the "Trust Agreement"), between the Seller and Deutsche Bank Trust Company Delaware, as owner trustee (the "Owner Trustee"), a summary of certain of the pertinent provisions of which is set forth below. To the extent not otherwise defined herein, the capitalized terms used herein have the meanings assigned to them in the Trust Agreement.

This is the duly authorized Certificate designated as "Asset Backed Certificate" (herein called the "Certificate"). Also issued under the Indenture, dated as of May 14, 2003, among the Trust, JPMorgan Chase Bank, as trustee and indenture collateral agent, are six classes of Notes designated as "Class A-1 1.29% Asset Backed Notes" (the "Class A-1 Notes"), "Class A-2-A 1.55% Asset Backed Notes" (the "Class A-2-A Notes"), "Class A-2-B Floating Rate Asset Backed Notes" (the "Class A-2-B Notes"), "Class A-3 2.11% Asset Backed Notes" (the "Class A-3 Notes"), "Class A-4-A 2.72% Asset Backed Notes" (the "Class A-4-A Notes") and "Class A-4-B Floating Rate Asset Backed Notes" (the "Class A-4-B Notes" and together with the Class A-1 Notes, the Class A-2-A Notes, the Class A-2-B Notes, the Class A-3 Notes and the Class A-4-A Notes, the "Notes"). This Certificate is issued under and is

subject to the terms, provisions and conditions of the Trust Agreement, to which Trust Agreement the holder of this Certificate by virtue of the acceptance hereof assents and by which such holder is bound. The property of the Trust includes a pool of retail installment sale contracts secured by new and used automobiles, vans or light duty trucks (the "Receivables"), all monies due thereunder on or after Cutoff Date, security interests in the vehicles financed thereby, certain bank accounts and the proceeds thereof, proceeds from claims on certain insurance policies and certain other rights under the Trust Agreement and the Sale and Servicing Agreement, all right, to and interest of the Seller in and to the Purchase Agreement dated as of May 14, 2003 among AmeriCredit Financial Services, Inc. and the Seller and all proceeds of the foregoing.

The holder of this Certificate acknowledges and agrees that its rights to receive distributions in respect of this Certificate are subordinated to the rights of the Noteholders as described in the Sale and Servicing Agreement, the Indenture and the Trust Agreement, as applicable.

Distributions on this Certificate will be made as provided in the Trust Agreement by the Owner Trustee by wire transfer or check mailed to the Certificateholder without the presentation or surrender of this Certificate or the making of any notation hereon. Except as otherwise provided in the Trust Agreement and notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Owner Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency maintained for the purpose by the Owner Trustee in the Borough of Manhattan, The City of New York.

(Reverse of Certificate)

The Certificate does not represent an obligation of, or an interest in, the Seller, the Servicer, the Owner Trustee or any Affiliates of any of them and no recourse may be had against such parties or their assets, except as may be expressly set forth or contemplated herein or in the Trust Agreement, the Indenture or the Basic Documents. In addition, this Certificate is not guaranteed by any governmental agency or instrumentality and is limited in right of payment to certain collections with respect to the Receivables, all as more specifically set forth herein and in the Sale and Servicing Agreement. A copy of each of the Sale and Servicing Agreement and the Trust Agreement may be examined during normal business hours at the principal office of the Seller, and at such other places, if any, designated by the Seller, by any Certificateholder upon written request.

The Trust Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Seller under the Trust Agreement at any time by the Seller and the Owner Trustee with the consent of the Note Majority and the Certificateholder. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and on all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Trust Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Certificateholder.

As provided in the Trust Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies of the Certificate Registrar maintained by the Owner Trustee in the Borough of Manhattan, The City of New York, accompanied by a written instrument of transfer in form satisfactory to the Owner Trustee and the Certificate Registrar duly executed by the holder hereof or such holder's attorney duly authorized in writing, and thereupon a new Certificate evidencing the same aggregate interest in the Trust will be issued to the designated transferee. The initial Certificate Registrar appointed under the Trust Agreement is Deutsche Bank Trust Company Americas. No service charge will be made for any such registration of transfer or exchange, but the Owner Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

The Owner Trustee, the Security Insurer and any agent of the Owner Trustee or the Security Insurer may treat the person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Owner Trustee, the Security Insurer nor any such agent shall be affected by any notice to the contrary.

The obligations and responsibilities created by the Trust Agreement and the Trust created thereby shall terminate upon the payment to the Certificateholder of all amounts required to be paid to it pursuant to the Trust Agreement and the Sale and Servicing Agreement and the disposition of all property held as part of the Trust. The Seller or the Servicer of the Receivables may at its option purchase the corpus of the Trust at a price specified in the Sale and Servicing Agreement, and such purchase of the Receivables and other property of the Trust will effect early retirement of the Certificate; however, such right of purchase is exercisable, subject to certain restrictions, only as of the last day of any Collection Period as of which the Pool Balance is 10% or less of the Original Pool Balance.

The Certificate may not be acquired by (a) an employee benefit plan (as defined in Section 3(3) of ERISA) that is subject to the provisions of Title I of ERISA, (b) a plan (as defined in Section 4975(e)(1) of the Code) that is subject to subject to Section 4975 or (c) any entity whose underlying assets include assets of a plan described in (a) or (b) above by reason of such plan's investment in the entity (each, a "Benefit Plan"). By accepting and holding this Certificate, the Holder hereof shall be deemed to have represented and warranted that it is not a Benefit Plan.

The recitals contained herein shall be taken as the statements of the Depositor or the Servicer, as the case may be, and the Owner Trustee assumes no responsibility for the correctness thereof. The Owner Trustee makes no representations as to the validity or sufficiency of this Certificate or of any Receivable or related document.

Unless the certificate of authentication hereon shall have been executed by an authorized officer of the Owner Trustee, by manual or facsimile signature, this Certificate shall not entitle the Holder hereof to any benefit under the Trust Agreement or the Sale and Servicing Agreement or be valid for any purpose.
