ARTICLE III

THE ADMINISTRATOR

SECTION 3.1 Representations and Warranties of the Administrator. The Administrator represents and warrants to the Issuer and the Indenture Trustee as follows:

(a)   Existence and Power. The Administrator is a corporation validly existing and in good standing under the laws of its state of organization and has, in all material respects, full power and authority to own its assets and operate its business as presently owned or operated, and to execute, to deliver and to perform its obligations under the Transaction Documents to which it is a party. The Administrator has obtained all necessary licenses and approvals in each jurisdiction where the failure to do so would materially and adversely affect the ability of the Administrator to perform its obligations under the Transaction Documents or affect the enforceability or collectability of the Receivables or any other part of the Collateral.

(b)   Authorization and No Contravention. The execution, delivery and performance by the Administrator of the Transaction Documents to which it is a party have been duly authorized by all necessary action on the part of the Administrator and do not contravene or constitute a default under (i) any applicable law, rule or regulation, (ii) its organizational documents or (iii) any material agreement to which the Administrator is a party by which its properties are bound (other than violations of such laws, rules, regulations, organizational documents or agreements which do not affect the legality, validity or enforceability of any of such agreements and which, individually or in the aggregate, would not materially and adversely affect the transactions contemplated by, or the Administrator’s ability to perform its obligations under, the Transaction Documents).

(c)   No Consent Required. No approval or authorization by, or filing with, any Governmental Authority is required in connection with the execution, delivery and performance by the Administrator of any Transaction Document other than (i) UCC filings, (ii) approvals and authorizations that have previously been obtained and filings that have previously been made and (iii) approvals, authorizations or filings which, if not obtained or made, would not have a material adverse effect on the enforceability or collectability of the Receivables or any other part of the Collateral or would not materially and adversely affect the ability of the Administrator to perform its obligations under the Transaction Documents.

(d)   Binding Effect. Each Transaction Document to which the Administrator is a party constitutes the legal, valid and binding obligation of the Administrator enforceable against the Administrator in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, receivership, conservatorship or other similar laws affecting the enforcement of creditors’ rights generally and, if applicable, the rights of creditors of corporations from time to time in effect or by general principles of equity.

SECTION 3.2 Not applicable to Santander Consumer in other Capacities. Nothing in this Agreement shall affect any obligation Santander Consumer may have in any other capacity.

SECTION 3.3 Merger of Administrator. Any entity (i) into which the Administrator may be merged or converted or with which it may be consolidated, to which it may sell or transfer its business and assets as a whole or substantially as a whole or any entity resulting from any merger, sale, transfer, conversion or consolidation to which the Administrator shall be a party, or any entity succeeding to the business of the Administrator or (ii) (A) more than 50% of the voting stock or voting power and 50% or more of the economic equity of which is owned directly or indirectly by Banco Santander, S.A. and (B) which executes an agreement of assumption to perform every obligation of the Administrator under this Agreement, shall be the successor to the Administrator under this Agreement, in each case, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 3.4 The Administrator May Own Notes. The Administrator, and any Affiliate of the Administrator, may, in its individual or any other capacity, become the owner or pledgee of Notes with the same rights as it would have if it were not the Administrator or an Affiliate thereof, except as otherwise expressly provided herein or in the other Transaction Documents. Except as set forth herein or in the other Transaction Documents, Notes so owned by or pledged to the Administrator or such Affiliate will have an equal and proportionate benefit under the provisions of this Agreement, without preference, priority or distinction as among all of the Notes.

SECTION 3.5 Liens. The Administrator will not directly or indirectly create, suffer or allow to exist any Lien on the Collateral other than Permitted Liens.

SECTION 3.6 Other Activities of the Administrator. Nothing herein shall prevent the Administrator or its Affiliates from engaging in other businesses or, in its sole discretion, from acting in a similar capacity as an Administrator for any other Person even though such Person may engage in business activities similar to those of the Issuer, the Owner Trustee or the Indenture Trustee.

SECTION 3.7 Form 8-K Filings. The Administrator shall promptly notify the Seller, but in no event later than two (2) Business Days after its occurrence, of any Reportable Event of which a Responsible Officer of the Administrator has actual knowledge (other than a Reportable Event described in clause (a) or (b) of the definition thereof as to which the Seller or the Administrator 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 3.8 Regulation AB. The Administrator shall cooperate fully with the Seller and the Issuer to deliver to the Seller and the Issuer (including any of its assignees or designees) any and all statements, reports, certifications, records and any other information necessary in the good faith determination of the Seller or the Issuer to permit the Seller to comply with the provisions of Regulation AB and its reporting obligations under the Exchange Act.

No Eligible Investment shall be sold or otherwise disposed of prior to its scheduled maturity unless a default occurs with respect to such Eligible Investment and the Administrator directs the Relevant Trustee in writing to dispose of such Eligible Investment. The Administrator acknowledges that upon its written request and at no additional cost, it has the right to receive notification after the completion of each purchase and sale of Eligible Investments or the Relevant Trustee’s receipt of a broker’s confirmation. The Administrator agrees that such notifications shall not be provided by the Relevant Trustee hereunder, and the Relevant Trustee shall make available, upon request and in lieu of notifications, periodic account statements that reflect such investment activity.

(c)   The Relevant Trustee shall possess all right, title and interest in all funds on deposit from time to time in the Trust Accounts and in all proceeds thereof and all such funds, investments and proceeds shall be part of the Trust Estate. Except as otherwise provided herein, the Trust Accounts shall be under the sole dominion and control of the Relevant Trustee for the benefit of the Noteholders (or if there are no Noteholders, for the Certificateholders). If, at any time, any Trust Account ceases to be an Eligible Account, the Administrator shall promptly notify the Relevant Trustee (unless such Trust Account is an account with the Relevant Trustee) in writing and within thirty (30) days (or any longer period if the Rating Agency Condition is satisfied with respect to such longer period) after becoming aware of the fact, establish a new Trust Account as an Eligible Account and shall direct the Relevant Trustee in writing to transfer any cash and/or any investments to such new Trust Account.

(d)   With respect to the Trust Account Property, the parties hereto agree that:

(e)   The Indenture Trustee, to the extent it is acting in the capacity of securities intermediary with respect to Trust Account Property, represents, warrants and covenants that:

(f)   To the extent that there are any other agreements with the Indenture Trustee governing the Trust Accounts, the parties agree that each and every such agreement is hereby amended to provide that, with respect to the Trust Accounts, the law applicable to all issues specified in Article 2(1) of the Hague Securities Convention shall be the laws of the State of New York.

(g)   Except for the Collection Account, the Reserve Account and the Certificate Distribution Account, there are no accounts required to be maintained under the Transaction Documents.
