ARTICLE II

CONVEYANCE OF TRANSFERRED ASSETS; PROTECTION OF TITLE

SECTION 2.1 Conveyance of Transferred Assets. In consideration of the Issuer’s sale and delivery to, or upon the order of, the Seller of all of the Notes and the Certificate on the Closing Date, the Seller does hereby irrevocably sell, transfer, assign and otherwise convey to the Issuer without recourse (subject to the obligations herein) all right, title and interest of the Seller, whether now owned or hereafter acquired, in, to and under the Transferred Assets, as evidenced by an assignment substantially in the form of Exhibit A hereto delivered on the Closing Date. The sale, transfer, assignment and conveyance made hereunder does not constitute and is not intended to result in an assumption by the Issuer of any obligation of the Seller or the Originator to the Obligors, the Dealers, insurers or any other Person in connection with the Receivables or the other assets and properties conveyed hereunder or any agreement, document or instrument related thereto.

SECTION 2.2 Protection of Title.

(a) The Seller shall authorize and file such financing statements and cause to be authorized and filed such continuation and other financing statements, all in such manner and in such places as may be required by law fully to preserve, maintain and protect the interest of the Issuer and the Indenture Trustee under this Agreement in the Purchased Assets (to the extent that the interest of the Issuer or the Indenture Trustee therein can be perfected by the filing of a financing statement). The Seller shall deliver (or cause to be delivered) to the Issuer file-stamped copies of, or filing receipts for, any document filed as provided above, as soon as available following such filing.

(b) The Seller shall notify the Issuer and the Administrator in writing within ten (10) days following the occurrence of (i) any change in the Seller’s organizational structure and (ii) any change in the Seller’s name. The Seller shall take all action prior to making such change (or shall have made arrangements to take such action substantially simultaneously with such change, if it is not possible to take such action in advance) reasonably necessary to amend all previously filed financing statements or continuation statements described in clause (a) above to maintain perfection of the Issuer in the Receivables and shall have delivered to the Indenture Trustee within thirty (30) days after such change an Opinion of Counsel either (A) stating that, in the opinion of such counsel, all financing statements and continuation statements and amendments thereto have been executed and filed that are necessary to preserve and protect the interest of the Issuer in the Receivables or (B) stating that, in the opinion of such counsel, no such action shall be necessary to preserve and protect such interest.

(c) The Seller shall give the Issuer, the Administrator and the Indenture Trustee at least five days’ prior written notice of any change of location of the Seller for purposes of Section 9-307 of the UCC and shall have taken all action prior to making such change (or shall have made arrangements to take such action substantially simultaneously with such change, if it is not practicable to take such action in advance) reasonably necessary or advisable to amend all previously filed financing statements or continuation statements described in clause (a) above.


		2		Sale Agreement (SDART 2026-1)

SECTION 2.3 Other Liens or Interests. Except for the conveyances and grants of security interests pursuant to this Agreement and the other Transaction Documents, the Seller shall not sell, pledge, assign or transfer the Receivables or other property transferred to the Issuer to any other Person, or grant, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) on any interest therein, and the Seller shall defend the right, title and interest of the Issuer in, to and under such Receivables and other property transferred to the Issuer against all claims of third parties claiming through or under the Seller.

SECTION 2.4 Transfers Intended as Sales; Security Interest.

(a) Each of the parties hereto expressly intends and agrees that the transfers contemplated and effected under this Agreement are complete and absolute sales, transfers, assignments and conveyances rather than pledges or assignments of only a security interest and shall be given effect as such for all purposes. It is further the intention of the parties hereto that the Receivables and related Transferred Assets shall not be part of the Seller’s estate in the event of a bankruptcy or insolvency of the Seller. The sales and transfers by the Seller of Receivables and related Transferred Assets hereunder are and shall be without recourse to, or representation or warranty (express or implied) by, the Seller, except as otherwise specifically provided herein. The limited rights of recourse specified herein against the Seller are intended to provide a remedy for breach of representations and warranties relating to the condition of the property sold, rather than to the collectability of the Receivables.

(b) Notwithstanding the foregoing, in the event that the Receivables and other Transferred Assets are held to be property of the Seller, or if for any reason this Agreement is held or deemed to create indebtedness or a security interest in the Receivables and other Transferred Assets, then it is intended that:

(i)

This Agreement shall be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York UCC and the UCC of any other applicable jurisdiction;

(ii)

The conveyance provided for in Section 2.1 shall be deemed to be a grant by the Seller of, and the Seller hereby grants to the Issuer, a security interest in all of its right (including the power to convey title thereto), title and interest, whether now owned or hereafter acquired, in and to the Receivables and other Transferred Assets, to secure such indebtedness and the performance of the obligations of the Seller hereunder;

(iii)

The possession by the Issuer, or the Servicer as the Issuer’s agent, of the Receivable Files and any other property that constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “possession by the secured party” or possession by the purchaser or a person designated by such purchaser, for purposes of perfecting the security interest pursuant to the New York UCC and the UCC of any other applicable jurisdiction; and


		3		Sale Agreement (SDART 2026-1)

(iv)

Notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed to be notifications to, or acknowledgments, receipts or confirmations from, bailees or agents, as applicable, of the Issuer for the purpose of perfecting such security interest under applicable law.

ARTICLE III

THE SELLER

SECTION 3.1 Representations and Warranties of Seller. The Seller makes the following representations and warranties as of the Closing Date on which the Issuer will be deemed to have relied in acquiring the Transferred Assets. The representations and warranties speak as of the execution and delivery of this Agreement and will survive the conveyance of the Transferred Assets to the Issuer and the pledge thereof by the Issuer to the Indenture Trustee for the benefit of the Noteholders pursuant to the Indenture:

(a) Existence and Power. The Seller is validly existing under the laws of its jurisdiction of formation 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 Seller 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 Seller to perform its obligations under the Transaction Documents or affect the enforceability or collectability of the Receivables or any other part of the Transferred Assets.

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


		4		Sale Agreement (SDART 2026-1)

(d) Binding Effect. Each Transaction Document to which the Seller is a party constitutes the legal, valid and binding obligation of the Seller enforceable against the Seller 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 from time to time in effect or by general principles of equity.

(e) Lien Filings. The Seller is not aware of any material judgment, ERISA or tax lien filings against the Seller.

(f) No Proceedings. There are no actions, orders, suits, investigations or Proceedings pending or, to the knowledge of the Seller, threatened against the Seller before or by any Governmental Authority that (i) assert the invalidity or unenforceability of this Agreement or any of the other Transaction Documents or (ii) seek any determination or ruling that would materially and adversely affect the performance by the Seller of its obligations under this Agreement or any of the other Transaction Documents.

(g) Investment Company Act. The Seller is not an “investment company” that is registered or required to be registered under, or otherwise subject to the restrictions of the Investment Company Act of 1940, as amended.

(h) Assignment. The Receivables and the other Transferred Assets have been validly assigned by the Seller to the Issuer.

(i) Security Interests. The Seller has not authorized the filing of and is not aware of any financing statements against the Seller that include a description of collateral covering any Receivable other than any financing statement relating to security interests granted under the Transaction Documents or that have been or, prior to the assignment of such Receivables hereunder, will be terminated, amended or released. This Agreement creates a valid and continuing security interest in the Receivables (other than the Related Security with respect thereto, to the extent that an ownership interest therein cannot be perfected by the filing of a financing statement) in favor of the Issuer which security interest is prior to all other Liens (other than Permitted Liens) and is enforceable as such against all other creditors of and purchasers and assignees from the Seller.

(j) Creation, Perfection and Priority of Security Interests. The representations and warranties regarding creation, perfection and priority of security interests in the Transferred Assets, which are attached to this Agreement as Exhibit B, are true and correct.

(k) Reserve Account Deposit. On the Closing Date the Seller will cause the amount available in the Reserve Account to equal the Initial Reserve Account Deposit Amount through a cash deposit from proceeds of the sale of the Notes.

SECTION 3.2 Merger or Consolidation of, or Assumption of the Obligations of, Seller. Any entity (i) into which the Seller 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 Seller shall be a party, or any entity succeeding to the business of the Seller or (ii) (A) more than 50% of the


		5		Sale Agreement (SDART 2026-1)

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 Seller under this Agreement, shall be the successor to the Seller under this Agreement, in each case, without the execution or filing of any additional paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. Within thirty days following the consummation of any of the foregoing transactions in which the Seller is not the surviving entity, the Seller shall deliver to the Indenture Trustee an Opinion of Counsel either (A) stating that, in the opinion of such counsel, all financing statements and continuation statements and amendments thereto have been executed and filed that are necessary to preserve and protect the interest of the Issuer in the Receivables and the other Transferred Assets or (B) stating that, in the opinion of such counsel, no such action shall be necessary to preserve and protect such interest.

SECTION 3.3 Limitation on Liability of Seller and Others. The Seller and any officer or employee or agent of the Seller 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. The Seller will not be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its obligations under this Agreement and that in its opinion may involve it in any expense or liability.

SECTION 3.4 Seller May Own Notes. The Seller, and any Affiliate of the Seller, 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 Seller 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 the Seller or any such Affiliate will have an equal and proportionate benefit under the provisions of this Agreement and the other Transaction Documents, without preference, priority, or distinction as among all of the Notes. Unless all Notes are owned by the Issuer, the Seller, any Certificateholder, the Sponsor, the Servicer, the Administrator or any of their respective Affiliates, any Notes owned by the Issuer, the Seller, any Certificateholder, the Sponsor, the Servicer, the Administrator or any of their respective Affiliates shall be disregarded with respect to the determination of any request, demand, authorization, direction, notice, consent, vote or waiver hereunder or under any other Transaction Document.

SECTION 3.5 Sarbanes-Oxley Act Requirements. To the extent any documents are required to be filed or any certification is required to be made with respect to the Issuer or the Notes pursuant to the Sarbanes-Oxley Act, the Issuer hereby authorizes the Seller to prepare, sign, certify and file any such documents or certifications on behalf of the Issuer.

SECTION 3.6 Compliance with Organizational Documents. The Seller shall comply in all material respects with its limited liability company agreement and other organizational documents.

SECTION 3.7 Compliance with the FDIC Rule. If an FDIC Safe Harbor Compliance Event has occurred and is continuing, the Seller (i) shall perform the covenants set forth in Article XII of the Indenture applicable to it and (ii) shall facilitate compliance with Article XII of the Indenture by the Bank Parties.
