 ARTICLE II 

CONVEYANCE OF TRANSFERRED ASSETS 

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 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 Custody of Receivable Files. 

(a) Custody. To assure uniform quality in servicing the Receivables and to reduce administrative costs, the Issuer and the Indenture
Trustee, not in its individual capacity but solely as Indenture Trustee, upon the execution and delivery of this Agreement, hereby revocably appoint 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 Receivable Files, which are hereby or will hereby be constructively delivered to the Indenture Trustee (or its agent or designee), as pledgee of the Issuer pursuant to the Indenture. “Receivable
File” means, with respect to each Receivable, the following documents or instruments (but only to the extent applicable to such Receivable), which may be held in tangible paper form or electronic form: 

 

	 	(i)	the fully executed original, electronically authenticated original or authoritative copy of the Contract (in each case within the meaning of the UCC) related to such Receivable, including any written amendments or
extensions thereto; 

  

	 	(ii)	the original Certificate of Title or, if not yet received, evidence that an application therefor has been submitted with the appropriate authority, a guaranty of title from a Dealer or such other document (electronic or
otherwise, as used in the applicable jurisdiction) that the Servicer keeps on file, in accordance with its Customary Servicing Practices, evidencing the security interest of the Originator in the Financed Vehicle; provided, however,
that in lieu of being held in the Receivable File, the Certificate of Title may be held by a third party service provider engaged by the Servicer to obtain and/or hold Certificates of Title; and 


  

					
		 	2	  	Sale and Servicing Agreement (SDART 2018-3)









	 	(iii)	any and all other documents that the Servicer or the Seller keeps on file, in accordance with its Customary Servicing Practices, relating to a Receivable, an Obligor or a Financed Vehicle. 


(b) Safekeeping. The Servicer, in its capacity as custodian, shall hold the Receivable Files for the benefit of the Issuer and the
Indenture Trustee, as pledgee of the Issuer. In performing its duties as custodian, the Servicer shall act in accordance with its Customary Servicing Practices. The Servicer will promptly report to the Issuer and the Indenture Trustee any failure on
its part to hold a material portion of the Receivable Files or to maintain its accounts, records, and computer systems as herein provided and shall promptly take appropriate action to remedy any such failure. Nothing herein will be deemed to require
an initial review or any periodic review by the Issuer or the Indenture Trustee of the Receivable Files. The Servicer may, in accordance with its Customary Servicing Practices, (i) maintain all or a portion of the Receivable Files in electronic
form and (ii) maintain custody of all or any portion of the Receivable Files with one or more of its agents or designees. 
 (c)
Maintenance of and Access to Records. The Servicer will maintain each Receivable File in the United States (it being understood that the Receivable Files, or any part thereof, may be maintained at the offices of any Person to whom the
Servicer has delegated responsibilities in accordance with Section 6.5). The Servicer will make available to the Issuer and the Indenture Trustee or their duly authorized representatives, attorneys or auditors a list of
locations of the Receivable Files upon request. The Servicer will provide access to the Receivable Files, and the related accounts records, and computer systems maintained by the Servicer at such times as the Issuer or the Indenture Trustee direct,
but only upon reasonable notice and during the normal business hours at the respective offices of the Servicer. 
 (d) Release of
Documents. Upon written instructions from the Indenture Trustee, the Servicer will 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 designate, as soon thereafter as is practicable. Any document so released will be handled by the Indenture Trustee with reasonable care and returned to the Servicer
for safekeeping as soon as the Indenture Trustee or its agent or designee, as the case may be, has no further need therefor. 
 (e)
Instructions; Authority to Act. All instructions from the Indenture Trustee will be in writing and signed by an Authorized Officer of the Indenture Trustee, and the Servicer will be deemed to have received proper instructions with respect to
the Receivable Files upon its receipt of such written instructions. 
 (f) Custodian’s Indemnification. Subject to
Section 6.2, the Servicer as custodian will indemnify the Issuer and the Indenture Trustee for any and all liabilities, obligations, losses, compensatory damages, payments, costs, or expenses (including reasonable
attorneys’ fees and expenses and court costs and any losses incurred in connection with a successful defense, in whole or part, of any claim that the Indenture Trustee breached its standard of care and legal fees and expenses incurred in
actions against the indemnifying party) of any kind whatsoever that may be imposed on, incurred by or asserted against the Issuer or the Indenture Trustee as the result of any improper act or omission in any way relating to the maintenance and
custody by the 

  

					
		 	3	  	Sale and Servicing Agreement (SDART 2018-3)








 
Servicer as custodian of the Receivable Files or the enforcement of the Issuer’s or Indenture Trustee’s rights (including indemnification rights) under the Transaction Documents;
provided, however, that the Servicer as custodian will not be liable (i) to the Indenture Trustee or the Issuer for any portion of any such amount resulting from the willful misconduct, bad faith or negligence of the Indenture
Trustee or the Issuer, respectively, or (ii) to the Indenture Trustee for any portion of any such amount resulting from the failure of the Indenture Trustee, the Indenture Trustee’s agent or the Indenture Trustee’s designee to handle
with reasonable care any Certificate of Title or other document released to the Indenture Trustee, the Indenture Trustee’s agent or the Indenture Trustee’s designee pursuant to Section 2.2(d). The provisions of
this Section 2.2(f) shall survive the termination or assignment of this Agreement and the resignation or removal of the Indenture Trustee or Servicer, in its capacity as custodian. 

(g) Effective Period and Termination. The Servicer’s appointment as custodian will become effective as of the Cut-Off Date and will continue in full force and effect until terminated pursuant to this Section. If Santander Consumer resigns as Servicer in accordance with the provisions of this Agreement or if all of the
rights and obligations of the Servicer 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 Noteholders of Notes evidencing not
less than a majority of the Note Balance of the Controlling Class (or, if the Notes are no longer Outstanding, by the Majority Certificateholders), in the same manner as the Indenture Trustee or such Noteholders (or Certificateholders) 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 will deliver to the Indenture Trustee (or, at the direction of the Indenture
Trustee, to its 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; provided, however, that with respect to
authoritative copies of the Receivables constituting electronic chattel paper, the Servicer, in its sole discretion, shall either (i) continue to hold any such authoritative copies on behalf of the Issuer and the Indenture Trustee or the
Indenture Trustee’s agent (provided that the Servicer has not been terminated in accordance with the provisions of this Section 2.2(g)) or (ii) deliver copies of such authoritative copies and destroy the
authoritative copies maintained by the Servicer prior to its termination such that the copy delivered to the Indenture Trustee or the Indenture Trustee’s agent becomes the authoritative copy of the Receivable constituting electronic chattel
paper. 
 (h) Liability of Indenture Trustee. The Indenture Trustee shall not be liable for the acts or omissions of the Servicer, in
its capacity as custodian of the Receivable Files.

 ARTICLE III 

ADMINISTRATION AND SERVICING OF 

RECEIVABLES AND TRUST PROPERTY 

SECTION 3.1 Duties of Servicer. 

(a) The Servicer is hereby appointed by the Issuer and authorized to act as agent for the Issuer and in such capacity shall manage, service,
administer and make collections on the Receivables, and perform the other actions required by the Servicer under this Agreement. The Servicer agrees that its servicing of the Receivables will be carried out in accordance with its Customary Servicing
Practices, using the degree of skill and attention that the Servicer exercises with respect to all comparable motor vehicle receivables that it services for itself or others. The Servicer’s duties will include collection and posting of all
payments, responding to inquiries of Obligors on such Receivables, investigating delinquencies, sending invoices or payment coupons to Obligors, reporting any required tax information to Obligors, accounting for Collections and furnishing monthly
and annual statements to the Indenture Trustee with respect to distributions and performing the other duties specified herein. The Servicer is not required under the Transaction Documents to make any disbursements via wire transfer or otherwise on
behalf of an Obligor. There are no requirements under the Receivables or the Transaction Documents for funds to be, and funds shall not be, held in trust for an Obligor. No payments or disbursements shall be made by the Servicer on behalf of the
Obligor. The Servicer hereby accepts such appointment and authorization and agrees to perform the duties of Servicer with respect to the Receivables set forth herein. 

(b) The Servicer will follow its Customary Servicing Practices and will have full power and authority to do any and all things in connection
with such managing, servicing, administration and collection that it may deem necessary or desirable. 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 the Receivables or to the Financed Vehicles securing such Receivables. The Servicer is hereby authorized to commence, in its own name or in the name of the Issuer, a legal proceeding to enforce a Receivable or an Insurance Policy or to
commence or participate in any other legal proceeding (including a bankruptcy proceeding) relating to or involving a Receivable, an Obligor, a Financed Vehicle or an Insurance Policy. If the Servicer commences a legal proceeding to enforce a
Receivable or an Insurance Policy, the Issuer will thereupon be deemed to have automatically assigned such Receivable or its rights under such Insurance Policy to the Servicer solely for purposes of commencing or participating in any such proceeding
as a party or claimant, and the Servicer is authorized and empowered by the Issuer to execute and deliver in the Servicer’s name any notices, demands, claims, complaints, responses, affidavits or other documents or instruments in connection
with any such proceeding. If in any enforcement suit or legal proceeding it is held that the Servicer may not enforce a Receivable or Insurance Policy on the ground that it is not a real party in interest or a holder entitled to enforce the
Receivable or Insurance Policy, the Issuer will, at the Servicer’s expense and direction, take steps to enforce the 

  

					
		 	5	  	Sale and Servicing Agreement (SDART 2018-3)








 
Receivable or Insurance Policy, including bringing suit in its name or the name of the Indenture Trustee. The Issuer will 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. The Servicer, at its expense, will obtain on behalf of the Issuer all licenses, if any, required by the laws of any
jurisdiction to be held by the Issuer in connection with ownership of the Receivables, and will make all filings and pay all fees as may be required in connection therewith during the term hereof. 

(c) The Servicer hereby agrees that upon its resignation and the appointment of a successor Servicer hereunder, the Servicer will terminate its
activities as Servicer hereunder in accordance with Section 7.1, and, in any case, in a manner which the Indenture Trustee reasonably determines will facilitate the transition of the performance of such activities to such
successor Servicer, and the Servicer shall cooperate with and assist such successor Servicer. 
 (d) The Servicer shall not be required to
monitor whether Obligors maintain an Insurance Policy on the Financed Vehicles. 
 SECTION 3.2 Collection of Receivable
Payments. 
 (a) The Servicer will make reasonable efforts to collect all payments called for under the terms and provisions of the
Receivables as and when the same become due in accordance with its Customary Servicing Practices. Subject to Section 3.5, the Servicer may grant extensions, rebates, deferrals, amendments, modifications, temporary
reductions in payments or adjustments with respect to any Receivable in accordance with its Customary Servicing Practices; provided, however, that if the Servicer (i) extends the date for final payment by the Obligor of any
Receivable beyond the last day of the Collection Period immediately prior to the Class E Final Scheduled Payment Date, (ii) reduces the Contract Rate with respect to any Receivable other than as required by applicable law (including,
without limitation, the Servicemembers Civil Relief Act) or court order or (iii) reduces the Principal Balance with respect to any Receivable other than (A) as required by applicable law or court order, (B) in connection with a
settlement in the event the Receivable becomes a Defaulted Receivable or (C) in connection with a Cram Down Loss relating to such Receivable, it will promptly purchase such Receivable in the manner provided in, and subject to the conditions set
forth in, Section 3.6. The Servicer may in its discretion waive any late payment charge or any other fees that may be collected in the ordinary course of servicing a Receivable. The Servicer shall not be required to make
any advances of funds or guarantees regarding collections, cash flows or distributions. Payments on the Receivables, including payoffs, made in accordance with the related documentation for such Receivables, shall be posted to the Servicer’s
Obligor records in accordance with the Servicer’s Customary Servicing Practices. Such payments shall be allocated to principal, interest or other items in accordance with the related documentation for such Receivables. 

(b) Subject to the proviso of the second sentence of Section 3.2(a), the Servicer and its Affiliates may engage in
any marketing practice or promotion or any sale of any products, goods or services to Obligors with respect to the Receivables so long as such practices, promotions or sales are offered to obligors of comparable motor vehicle receivables serviced by
the Servicer for itself and others, whether or not such practices, promotions or sales might result in a decrease in the aggregate amount of payments on the Receivables, prepayments or faster or slower timing of the payment of the Receivables. 

  

					
		 	6	  	Sale and Servicing Agreement (SDART 2018-3)








 (c) Notwithstanding anything in this Agreement to the contrary, the Servicer may refinance any
Receivable and deposit the full outstanding Principal Balance of such Receivable into the Collection Account. The receivable created by such refinancing shall not be property of the Issuer. The Servicer and its Affiliates may also sell insurance or
debt cancellation products, including products which result in the cancellation of some or all of the amount of a Receivable upon the death or disability of the Obligor or any casualty with respect to the Financed Vehicle. 

(d) Records documenting collection efforts shall be maintained during the period a Receivable is delinquent in accordance with the
Servicer’s Customary Servicing Practices. Such records shall be maintained on at least a periodic basis that is not less frequent than as prescribed by the Servicer’s Customary Servicing Practices, and describe the entity’s activities
in monitoring delinquent pool assets including, for example, phone calls, letters and payment rescheduling plans in cases where delinquency is deemed temporary (e.g., illness or unemployment) in accordance with the Servicer’s Customary
Servicing Practices. 
 (e) The Servicer shall not be required to maintain a fidelity bond or errors and omissions policy. 

SECTION 3.3 Repossession of Financed Vehicles. On behalf of the Issuer, the Servicer will use commercially reasonable efforts,
consistent with its Customary Servicing Practices, to repossess or otherwise convert the ownership of and liquidate the Financed Vehicle securing any Receivable as to which the Servicer has determined eventual payment in full is unlikely; provided,
however, that the Servicer may elect not to repossess a Financed Vehicle if in its sole discretion it determines that repossession will not increase the amounts described in clauses (a) through (c) of the definition of Liquidation Proceeds by
an amount greater than the expense of such repossession or that the proceeds ultimately recoverable with respect to such Receivable would be increased by forbearance. The Servicer is authorized as it deems necessary or advisable, consistent with its
Customary Servicing Practices, to make reasonable efforts to realize upon any recourse to any Dealer and to sell the related Financed Vehicle at public or private sale. The foregoing will be subject to the provision that, in any case in which the
Financed Vehicle has suffered damage, the Servicer shall not be required to expend funds in connection with the repair or the repossession of such Financed Vehicle unless it determines in its sole discretion that such repair and/or repossession will
increase the amounts described in clauses (a) through (c) of the definition of Liquidation Proceeds with respect to such Financed Vehicle by an amount greater than the amount of such expenses. The Servicer, in its sole discretion, may in
accordance with its Customary Servicing Practices sell any Receivable’s deficiency balance. To facilitate any such sale the Servicer may, in accordance with its Customary Servicing Practices, purchase from the Issuer such Receivable’s
deficiency balance for a purchase price equal to the proceeds received by the Servicer in an arm’s-length transaction for the sale of such Receivable’s deficiency balance. Net proceeds of any such
sale allocable to the Receivable will constitute Liquidation Proceeds, and the sole right of the Issuer and the Indenture Trustee with respect to any such sold Receivables will be to receive such Liquidation Proceeds. Upon such sale, the Servicer
will mark its computer records indicating that any such receivable sold is no longer a Receivable. The Servicer is authorized to take any and all actions necessary or appropriate on behalf of the Issuer to evidence the sale of the Financed Vehicle
at a public or private sale or the sale of the Receivable to the Servicer to facilitate a deficiency balance sale pursuant to the provisions of this paragraph, in each case, free from any Lien or other interest of the Issuer or the Indenture
Trustee.

 SECTION 3.4 Maintenance of Security Interests in Financed Vehicles. The Servicer
will, in accordance with its Customary Servicing Practices, take such steps as are necessary to maintain perfection of the security interest created by each Receivable in the related Financed Vehicle. The provisions set forth in this Section are the
sole requirements under the Transaction Documents with respect to the maintenance of collateral or security on the Receivables. It is understood that the Financed Vehicles are the collateral and security for the Receivables, but that the Certificate
of Title with respect to a Financed Vehicle does not constitute collateral for that Receivable and merely evidences such security interest. 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. 

SECTION 3.5 Covenants of Servicer. Unless required by law or court order, the Servicer will not release the Financed Vehicle
securing any Receivable from the security interest granted by such Receivable in whole or in part except (i) in the event of payment in full by or on behalf of the Obligor thereunder or payment in full less a deficiency which the Servicer would
not attempt to collect in accordance with its Customary Servicing Practices, (ii) in connection with repossession or (iii) as may be required by an insurer in order to receive proceeds from any Insurance Policy covering such Financed
Vehicle. 
 SECTION 3.6 Purchase of Receivables Upon Breach. Upon discovery by any party hereto of a breach of any of the
covenants set forth in Section 3.2, 3.3, 3.4 or 3.5 which materially and adversely affects the interests of the Issuer or the Noteholders in any Receivable, the party discovering or receiving written
notice of such breach shall give prompt written notice thereof to the other parties hereto; provided, (i) that the delivery of a Servicer’s Certificate shall be deemed to constitute prompt notice by the Servicer and the Issuer of
such breach and (ii) the Indenture Trustee shall be deemed to have knowledge of such breach only if a Responsible Officer has actual knowledge thereof, including without limitation upon receipt of written notice; provided,
further, that the failure to give such notice shall not affect any obligation of the Servicer under this Section 3.6. If the breach materially and adversely affects the interests of the Issuer or the Noteholders in
such Receivable, then the Servicer shall either (a) correct or cure such breach or (b) purchase such Receivable from the Issuer, in either case on or before the Business Day before the Payment Date following the end of the Collection
Period which includes the 60th day (or, if the Servicer elects, an earlier date) after the date the Servicer became aware or was notified of such breach. Any such breach or failure will be deemed
not to have a material and adverse effect if such breach or failure does not affect the ability of the Issuer to receive and retain timely payment in full on such Receivable. Any such purchase by the Servicer shall be at a price equal to the related
Repurchase Price. In consideration for such purchase, the Servicer shall make (or shall cause to be made) a payment to the Issuer equal to the Repurchase Price by depositing such amount into the Collection Account prior to noon, New York City time,
on such date of purchase (or, if the Servicer elects, an earlier date). Upon payment of such

Repurchase Price by the Servicer, the Indenture Trustee, on behalf of the Noteholders, and the Issuer shall release and shall execute and deliver such instruments of release, transfer or
assignment, in each case without recourse or representation, as may be reasonably requested by the Servicer to evidence such release, transfer or assignment or more effectively vest in the Servicer or its designee all of the Issuer’s and
Indenture Trustee’s rights in any Receivable and related Transferred Assets purchased pursuant to this Section 3.6. It is understood and agreed that the obligation of the Servicer to purchase any Receivable as
described above shall constitute the sole remedy respecting such breach available to the Issuer and the Indenture Trustee. 
 SECTION
3.7 Servicing Fee. On each Payment Date, the Indenture Trustee on behalf of the Issuer shall pay to the Servicer the Servicing Fee in accordance with Section 4.4 for the immediately preceding Collection Period as
compensation for its services. In addition, the Servicer will be entitled to retain all Supplemental Servicing Fees. The Servicer also will be entitled to receive investment earnings (net of investment losses and expenses) on funds on deposit in the
Collection Account and the Reserve Account during each Collection Period. 
 SECTION 3.8 Servicer’s
Certificate. On or before the Determination Date preceding each Payment Date, the Servicer shall deliver to the Indenture Trustee, the Owner Trustee and each Paying Agent, with a copy to each of the Rating Agencies, a Servicer’s Certificate

furnished by the Indenture Trustee to the Noteholders pursuant to Section 4.6 hereof and Section 6.6 of the Indenture. At the sole option of the Servicer, each Servicer’s Certificate may be
delivered in electronic format or hard copy format. 
 SECTION 3.9 Annual Officer’s Certificate; Notice of

Days after having obtained knowledge thereof written notice in an Officer’s Certificate of any event which with the giving of notice or lapse of time, or both, would become a Servicer Replacement Event. Except to the extent set forth in this
Section 3.9(b), Section 7.2 and Section 9.22 of this Agreement and Section 3.12 and Section 6.5 of the Indenture, the
Transaction Documents do not require any policies or procedures to monitor any performance or other triggers and events of default. 
 (c)
The Servicer will deliver to the Issuer, on or before March 30th of each year, beginning on March 30, 2019, a report regarding the Servicer’s assessment of compliance with the Servicing
Criteria specified in Exhibit C as applicable to the Servicer during the immediately preceding calendar year, including disclosure of any material instance of non-compliance identified by the Servicer,

Servicing Criteria with respect to the Servicer or any Affiliate thereof during the related fiscal year delivered by such accountants pursuant to paragraph (c) of Rule 13a-18 or Rule 15d-18 of the Exchange Act and Item 1122 of Regulation AB. The certification required by this paragraph may be replaced by any similar certification using other procedures or attestation standards which are now or

(b) The Servicer, however, shall not be obligated to deliver any report described above to any Person who does not comply with or agree to the
required procedures of such firm of independent certified public accountants, including but not limited to execution of engagement letters or access letters regarding such reports. 

SECTION 3.11 Servicer Expenses. The Servicer will be required to pay all expenses (other than Liquidation Expenses) incurred by
it in connection with its activities hereunder, including fees and disbursements of independent accountants, taxes imposed on the Servicer and expenses incurred in connection with distributions and reports to the Noteholders and the
Certificateholders. The Servicer will be entitled to retain an amount equal to the amount of Liquidation Expenses incurred during a Collection Period from Liquidation Proceeds received during such Collection Period. The Servicer shall pay
(i) fees, expenses, indemnities and disbursements of (x) the Indenture Trustee to the extent required under Section 6.7 of the Indenture, (y) the Owner Trustee to the extent required under Sections 8.1
and 8.2 of the Trust Agreement and (z) the Administrator and (ii) organizational expenses of the Issuer.

communicate with other Noteholders or Note Owners, as applicable, with respect to an exercise of their rights under the terms of the Transaction Documents. If the requesting party is not a Noteholder as reflected on the Note Register, the Seller may
require that the requesting party provide Verification Documents. Each request must include (i) the name of the requesting Noteholder or Note Owner, as applicable and (ii) a description of the method by which other Noteholders or Note

		 	10	  	Sale and Servicing Agreement (SDART 2018-3)

Issuer, the Seller shall include disclosure regarding any request that complies with the requirements of this Section 3.13 received during the related Collection Period from a Noteholder or Note Owner to communicate with
other Noteholders or Note Owners, as applicable, related to the Noteholders or Note Owners exercising their rights under the terms of the Transaction Documents. The disclosure in such Form 10-D regarding the
request to communicate shall include (w) the name of the investor making the request, (x) the date the request was received, (y) a statement to the effect that the Seller has received a request from such Noteholder or Note Owner, as

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

THE SELLER 
 SECTION
5.1 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 pursuant to the Indenture: 

  

					
		 	19	  	Sale and Servicing Agreement (SDART 2018-3)








 (a) Existence and Power. The Seller is a Delaware limited liability company 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 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 limited liability company 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 indenture or agreement to which the Seller is a party or by which its properties are bound (other than violations of such laws, rules, regulations, 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. 
 (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 of limited liability
companies 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,
(ii) seek to prevent the issuance of the Notes or the consummation of any of the transactions contemplated by this Agreement or any of the other Transaction Documents, (iii) 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 or the collectability or enforceability of the Receivables, or (iv) relate to the Seller that would materially and
adversely affect the federal or Applicable Tax State income, excise, franchise or similar tax attributes of the Notes. 

  

					
		 	20	  	Sale and Servicing Agreement (SDART 2018-3)








 (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
includes 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. 

SECTION 5.2 Liability of Seller; Indemnities. The Seller shall be liable in accordance herewith only to the extent of the
obligations specifically undertaken by the Seller under this Agreement, and hereby agrees to the following: 
 (a) The Seller shall
indemnify, defend, and hold harmless the Issuer, the Owner Trustee and the Indenture Trustee (including when performing its duties as Relevant Trustee) from and against any loss, liability or expense (including reasonable attorneys’ fees and
expenses and court costs and any losses incurred in connection with a successful defense, in whole or part, of any claim that the Indenture Trustee breached its standard of care and legal fees and expenses incurred in actions against the
indemnifying party) incurred by reason of the Seller’s violation of federal or State securities laws in connection with the registration or the sale of the Notes. 

(b) Indemnification under this Section 5.2 will survive the resignation or removal of the Owner Trustee or the
Indenture Trustee and the termination of this Agreement and will include, without limitation, reasonable fees and expenses of counsel and expenses of litigation including those incurred in connection with the enforcement of the Indenture
Trustee’s rights (including indemnification rights) under the Transaction Documents. If the Seller has made any indemnity payments pursuant to this Section 5.2 and the Person to or on behalf of whom such payments are
made thereafter collects any of such amounts from others, such Person will promptly repay such amounts to the Seller, without interest. 

  

					
		 	21	  	Sale and Servicing Agreement (SDART 2018-3)








 (c) The Seller’s obligations under this Section 5.2 are
obligations solely of the Seller and will not constitute a claim against the Seller to the extent that the Seller does not have funds sufficient to make payment of such obligations. In furtherance of and not in derogation of the foregoing, the
Issuer, the Servicer, the Indenture Trustee and the Owner Trustee, by entering into or accepting this Agreement, acknowledge and agree that they have no right, title or interest in or to the Other Assets of the Seller. To the extent that,
notwithstanding the agreements and provisions contained in the preceding sentence, the Issuer, the Servicer, the Indenture Trustee or the Owner Trustee either (i) asserts an interest or claim to, or benefit from, Other Assets, or (ii) is
deemed to have any such interest, claim to, or benefit in or from Other Assets, whether by operation of law, legal process, pursuant to applicable provisions of insolvency laws or otherwise (including by virtue of Section 1111(b) of the
Bankruptcy Code or any successor provision having similar effect under the Bankruptcy Code), then the Issuer, the Servicer, the Indenture Trustee or the Owner Trustee, as applicable, further acknowledges and agrees that any such interest, claim or
benefit in or from Other Assets is and will be expressly subordinated to the indefeasible payment in full of the other obligations and liabilities, which, under the terms of the relevant documents relating to the securitization or conveyance of such
Other Assets, are entitled to be paid from, entitled to the benefits of, or otherwise secured by such Other Assets (whether or not any such entitlement or security interest is legally perfected or otherwise entitled to a priority of distributions or
application under applicable law, including insolvency laws, and whether or not asserted against the Seller), including the payment of post-petition interest on such other obligations and liabilities. This subordination agreement will be deemed a
subordination agreement within the meaning of Section 510(a) of the Bankruptcy Code. The Issuer, the Servicer, the Indenture Trustee and the Owner Trustee each further acknowledges and agrees that no adequate remedy at law exists for a breach
of this Section 5.2(c) and the terms of this Section 5.2(c) may be enforced by an action for specific performance. The provisions of this Section 5.2(c) will be for the
benefit of those entitled to rely thereon and will survive the termination or assignment of this Agreement, and the resignation or removal of any indemnified party. 

SECTION 5.3 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) 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 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. 

  

					
		 	22	  	Sale and Servicing Agreement (SDART 2018-3)








 SECTION 5.4 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 5.5 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 Servicer, the Administrator or any of their respective Affiliates, any Notes owned by the Issuer, the Seller, any Certificateholder, 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 5.6 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 Servicer and the Seller, or either of them, to prepare, sign, certify and file any such documents or
certifications on behalf of the Issuer. 
 SECTION 5.7 Compliance with Organizational Documents. The Seller shall comply with
its limited liability company agreement and other organizational documents.

(a) Existence and Power. The Servicer is an Illinois corporation validly existing and in good standing under the laws of its state of

contemplated by, or the Servicer’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 Servicer of any Transaction Document other than (i) UCC filings,

if not obtained or made, would not have a material adverse effect on the enforceability or collectability of the Receivables or would not materially and adversely affect the ability of the Servicer to perform its obligations under the Transaction
Documents. 
 (d) Binding Effect. Each Transaction Document to which the Servicer is a party constitutes the legal, valid and binding
obligation of the Servicer enforceable against the Servicer 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 creditors’ rights generally and, if applicable, the rights of creditors of corporations from time to time in effect or by general principles of equity. 

(e) No Proceedings. There are no actions, suits, investigations or proceedings pending or, to the knowledge of the Servicer, threatened

SECTION 6.2 Indemnities of Servicer. The Servicer and the Issuer will be liable in accordance herewith only to the extent of the
obligations specifically undertaken by the Servicer and the Issuer, respectively, under this Agreement, and hereby agrees to the following: 

  

					
		 	24	  	Sale and Servicing Agreement (SDART 2018-3)








 (a) The Servicer will defend, indemnify and hold harmless the Issuer, the Owner Trustee, the
Indenture Trustee (including when performing its duties as Relevant Trustee) and the Seller from and against any and all costs, expenses (including reasonable attorneys’ fees and expenses and court costs and any losses incurred in connection
with a successful defense, in whole or part, of any claim that the Indenture Trustee breached its standard of care and legal fees and expenses incurred in actions against the indemnifying party), losses, damages, claims and liabilities, arising out
of or resulting from the use, ownership or operation by the Servicer or any Affiliate thereof or any sub-contractor hired by the Servicer or such Affiliate of a Financed Vehicle. 

(b) The Issuer, the Owner Trustee and the Indenture Trustee (including when performing its duties as Relevant Trustee) shall be indemnified,
defended and held harmless from and against any taxes that may at any time be asserted against any such Person with respect to the transactions contemplated herein or in the other Transaction Documents, if any, including, without limitation, 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, and as of the date of, the conveyance of the Receivables to the
Issuer or the issuance and original sales of the Notes, or asserted with respect to ownership of the Receivables, or federal or other Applicable Tax State income taxes arising out of the transactions contemplated by this Agreement and the other
Transaction Documents) and costs and expenses in defending against the same. For the avoidance of doubt, the Servicer will not indemnify for any costs, expenses, losses, claims, damages or liabilities due to the credit risk of the Obligors and for
which reimbursement would constitute recourse for uncollectible Receivables. Amounts payable pursuant to this Section 6.2(b) shall be payable (i) to the Indenture Trustee and the Owner Trustee pursuant to
Section 4.4(a) hereof or Section 5.4(b) of the Indenture, as applicable (to the extent of Available Funds available therefor), and, to the extent not paid thereunder, by the Servicer, and

 (c) The Servicer will indemnify, defend and hold harmless the Issuer, the Owner Trustee, the
Indenture Trustee (including when performing its duties as Relevant Trustee) and the Seller from and against any and all costs, expenses, losses, claims, damages, and liabilities to the extent that such cost, expense, loss, claim, damage, or
liability arose out of, or was imposed upon any such Person through, the negligence, willful misfeasance, or bad faith (other than errors in judgment) of the Servicer in the performance of its duties under this Agreement or any other Transaction
Document to which it is a party, or by reason of its failure to perform its obligations or of reckless disregard of its obligations and duties under this Agreement or any other Transaction Document to which it is a party; provided,
however, that the Servicer will not indemnify for any costs, expenses, losses, claims, damages or liabilities arising from its breach of any covenant for which the purchase of the affected Receivables is specified as the sole remedy pursuant
to Section 3.6. 
 (d) The Issuer or, if applicable, the Servicer will compensate and indemnify the Indenture
Trustee (including when performing its duties as Relevant Trustee) and the Owner Trustee to the extent and subject to the conditions set forth in Section 6.7 of the Indenture and Section 8.2 of the
Trust Agreement, as applicable, except, with respect to the Indenture Trustee, to the extent that any cost, expense, loss, claim, damage or liability arises out of or is incurred in connection with the performance by the Indenture Trustee of the
duties of a Successor Servicer hereunder. 

  

					
		 	25	  	Sale and Servicing Agreement (SDART 2018-3)








 (e) Indemnification under this Section 6.2 by Santander Consumer (or
any successor thereto pursuant to Section 7.1) as Servicer, with respect to the period such Person was the Servicer, will survive the termination or assignment of such Person as Servicer or a resignation by such Person as
Servicer as well as the termination or assignment of this Agreement or the resignation or removal of the Owner Trustee or the Indenture Trustee (including when performing its duties as Relevant Trustee) and will include reasonable fees and expenses
of counsel and expenses of litigation. If either the Issuer or the Servicer has made any indemnity payments pursuant to this Section 6.2 and the Person to or on behalf of whom such payments are made thereafter collects any
of such amounts from others, such Person will promptly repay such amounts to such party, without interest. 
 SECTION 6.3 Merger
or Consolidation of, or Assumption of the Obligations of, Servicer. Any entity (i) into which the Servicer 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 Servicer shall be a party, or any entity succeeding to the business of the Servicer or (ii) of which more than 50% of
the voting stock or voting power and 50% or more of the economic equity is owned directly or indirectly by Banco Santander, S.A. and which executes an agreement of assumption to perform every obligation of the Servicer under this Agreement, shall be
the successor to the Servicer 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 6.4 Limitation on Liability of Servicer and Others. 

(a) Neither the Servicer nor any of the directors or officers or employees or agents of the Servicer will be under any liability to the Issuer,
the Indenture Trustee, the Owner Trustee, the Noteholders or the Certificateholders, except as provided under this Agreement or the other Transaction Documents, 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 will 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 its failure to perform its obligations or of reckless disregard of obligations and duties under this Agreement, or by reason of negligence in the performance of its duties under this Agreement (except for errors
in judgment). The Servicer and any director, officer or employee or agent of the Servicer may rely in good faith on any Opinion of Counsel or on any Officer’s Certificate of the Seller or certificate of auditors believed to be genuine and to
have been signed by the proper party in respect of any matters arising under this Agreement. 
 (b) Except as provided in this Agreement, the
Servicer will not be under any obligation to appear in, prosecute, or defend any legal action that is not incidental to its duties to service the Receivables in accordance with this Agreement, and that in its opinion may involve it in any expense or
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 the Certificateholders under this Agreement. In such event, the legal expenses and costs of such action and any liability resulting therefrom will be expenses, costs and liabilities of the Servicer. 

  

					
		 	26	  	Sale and Servicing Agreement (SDART 2018-3)

consent, delegate (a) any or all of its duties (including, without limitation, its duties as custodian) under the Transaction Documents to any of its Affiliates or (b) specific duties (including, without limitation, its duties as
custodian) to sub-contractors who are in the business of performing such duties; provided, that no such delegation shall relieve the Servicer of its responsibility with respect to such duties and the
Servicer shall remain obligated and liable to the Issuer, the Indenture Trustee and, to the extent it is acting as Relevant Trustee, the Certificate Paying Agent for its duties hereunder as if the Servicer alone were performing such duties. For any
servicing activities delegated to third parties in accordance with this Section 6.5, the Servicer shall follow such policies and procedures to monitor the performance of such third parties and compliance with such servicing
activities as the Servicer follows with respect to comparable motor vehicle receivables serviced by the Servicer for its own account. 

SECTION 6.6 Santander Consumer Not to Resign as Servicer. Subject to the provisions of Sections 6.3 and 6.5,
Santander Consumer will not resign from the obligations and duties hereby imposed on it as Servicer under this Agreement except upon determination that the performance of its duties under this Agreement is no longer permissible under applicable law.
Notice of any such determination permitting the resignation of Santander Consumer will be communicated to the Issuer and the Indenture Trustee at the earliest practicable time (and, if such communication is not in writing, will be confirmed in
writing at the earliest practicable time) and any such determination will be evidenced by an Opinion of Counsel to such effect delivered to the Issuer and the Indenture Trustee concurrently with or promptly after such notice. No such resignation
will become effective until a successor Servicer has assumed the responsibilities and obligations of Santander Consumer as Servicer. 

SECTION 6.7 Servicer May Own Notes. The Servicer, and any Affiliate of the Servicer, 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 Servicer 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 Servicer 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. 
 ARTICLE VII 

TERMINATION OF SERVICER 

SECTION 7.1 Termination of Servicer. 

(a) If a Servicer Replacement Event shall have occurred and be continuing, the Indenture Trustee shall, at the direction of the Noteholders
representing at least a majority of the Note Balance of the Controlling Class (or, if no Notes are Outstanding, the Relevant Trustee shall, at the direction of the Majority Certificateholders), by notice given to the Servicer, the Owner Trustee, the
Issuer, the Administrator and the Noteholders, terminate the rights and obligations of the Servicer under this Agreement with respect to the Receivables. In the event the Servicer is removed or resigns as Servicer with respect to servicing the
Receivables, the Indenture Trustee shall appoint a successor Servicer. Upon the Servicer’s receipt of notice of 

  

					
		 	27	  	Sale and Servicing Agreement (SDART 2018-3)








 
termination, such Servicer will continue to perform its functions as Servicer under this Agreement only until the date specified in such termination notice or, if no such date is specified in
such termination notice, until receipt of such notice. If a successor Servicer has not been appointed at the time when the outgoing Servicer ceases to act as Servicer in accordance with this Section, the Indenture Trustee without further action will
automatically be appointed the successor Servicer. Notwithstanding the above, the Indenture Trustee, if it is legally unable or is unwilling to so act, will appoint, or petition a court of competent jurisdiction to appoint a successor Servicer. Any
successor Servicer shall be an established institution having a net worth of not less than $100,000,000 and whose regular business includes the servicing of comparable motor vehicle receivables having an aggregate outstanding principal amount of not
less than $50,000,000. 
 (b) Noteholders holding not less than a majority of the Note Balance of the Controlling Class (or, if no Notes are
Outstanding, the Majority Certificateholders) may waive any Servicer Replacement Event. Upon any such waiver, such Servicer Replacement Event shall cease to exist and be deemed not to have occurred, and any Servicer Replacement Event arising
therefrom shall be deemed not to have occurred for every purpose of this Agreement, but no such waiver shall extend to any prior, subsequent or other Servicer Replacement Event or impair any right consequent thereto. 

(c) If replaced, the Servicer agrees that it will use commercially reasonable efforts at its own expense to effect the orderly and efficient
transfer of the servicing of the Receivables to a successor Servicer. 
 (d) Upon the effectiveness of the assumption by the successor
Servicer of its duties pursuant to this Section 7.1, the successor Servicer shall be the successor in all respects to the Servicer in its capacity as Servicer under this Agreement with respect to the Receivables, and shall

of the Servicer, whether to complete the transfer and endorsement of the Receivables and related documents, or otherwise. No Servicer shall resign or be relieved of its duties under this Agreement, as Servicer of the Receivables, until a newly
appointed Servicer for the Receivables shall have assumed the responsibilities and obligations of the resigning or terminated Servicer under this Agreement. Notwithstanding anything else herein to the contrary, in no event shall the Indenture
Trustee be liable for any Servicing Fee or for any differential in the amount of the Servicing Fee paid hereunder and the amount necessary to induce any successor Servicer to act as successor Servicer under this Agreement and the transactions set
forth or provided for herein. 
 (e) In connection with such appointment, the Indenture Trustee may make such arrangements for the

		 	31	  	Sale and Servicing Agreement (SDART 2018-3)








 (e) The Servicer shall maintain (or shall cause its
Sub-Servicer to maintain) its computer systems so that, from time to time after the conveyance under this Agreement of the Receivables, the master computer records (including any backup archives) that refer to
a Receivable shall indicate clearly the interest of the Issuer in such Receivable and that such Receivable is owned by the Issuer and has been pledged to the Indenture Trustee on behalf of the Noteholders pursuant to the Indenture. Indication of the

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 9.4 Transfers Intended as Sale; 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:

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 as 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


  

	 	(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. 


SECTION 9.5 Information Requests. The parties hereto shall provide any information reasonably requested by the Servicer, the

of such Noteholder as shown in the Note Register. Delivery shall occur only upon receipt or reported tender of such communication by an officer of the recipient entitled to receive such notices located at the address of such recipient for notices
hereunder; provided, however, that any notice to a Noteholder mailed within the time and manner prescribed in this Agreement shall be conclusively presumed to have been duly given, whether or not the Noteholder shall receive such
notice.

SUBSTANTIVE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO THE RULES THEREOF RELATING TO CONFLICTS OF LAW, OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK
GENERAL OBLIGATIONS LAW, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement. 
 SECTION 9.13
Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. This Agreement shall create and constitute the continuing obligations of the parties
hereto in accordance with its terms, and shall remain in full force and effect until such time as the parties hereto shall agree. 

SECTION 9.14 Acknowledgment and Agreement. By execution below, the Seller expressly acknowledges and consents to the pledge,

however, that (i) if the Indenture Trustee declines to act in accordance with this Section 9.24 at the direction of a Noteholder or Note Owner due to the failure of such Noteholder or Note Owner to offer the
Indenture Trustee reasonable security or indemnity satisfactory to the Indenture Trustee against the reasonable costs, expenses, disbursement, advances and liabilities that might be incurred by it, its agents and its counsel in connection with such
act, such Noteholder or Note Owner shall be deemed to be a “Requesting Party” or (ii) if the Owner Trustee declines to act in accordance with this Section 9.24 at the direction of a Certificateholder due to
the failure of such Certificateholder to offer the Owner Trustee security or indemnity satisfactory to the Owner Trustee against the reasonable costs, expenses, disbursement, advances and liabilities that might be incurred by it, its agents and its
counsel in connection with such act, such Certificateholder shall be deemed to be a “Requesting Party.” If the Requesting Party is the Indenture Trustee or the Owner Trustee acting at the direction of a Noteholder, Note Owner or
Certificateholder, as applicable, the Indenture Trustee or Owner Trustee, as applicable, as Requesting Party, will act solely at the direction of such Noteholder, Note Owner, or Certificateholder in making all decisions related to mediation or
arbitration. Santander Consumer will inform the Requesting Party in writing upon a determination by Santander Consumer that a Receivable subject to a demand to repurchase will be repurchased and the monthly distribution report filed by the Seller on
Form 10-D for the Collection Period in which such Receivables were repurchased shall include disclosure of such repurchase. A failure of Santander Consumer to inform the Requesting Party that a Receivable
subject to a demand will be repurchased within 180 days of the receipt of notice of the request shall be deemed to be a determination by Santander Consumer that no repurchase of that Receivable due to a breach of
Section 3.3 of the Purchase Agreement is required. The monthly distribution report filed by the Seller on Form 10-D for the Collection Period in which a repurchase demand is made
and for each subsequent Collection Period until such repurchase demand is resolved or the related Receivable is repurchased, shall include disclosure regarding the date of the repurchase demand as well as the status of such repurchase demand for
each applicable Receivable. If both the Owner Trustee (on behalf of one or more Certificateholders) and the Indenture Trustee (on behalf of one or more Noteholders or Note Owners) are Requesting Parties, then the Indenture Trustee as Requesting
Party shall have the right to make the selection of mediation or arbitration. If more than one Noteholder or Note Owner has directed the Indenture Trustee in connection with a request to pursue dispute resolution pursuant to this
Section 9.24, the Indenture Trustee shall act at the direction of the Noteholders or Note Owners, as applicable, holding a majority of the Note Balance of the Notes held by such directing Noteholders and/or Note Owners. If
more than one Certificateholder has directed the Owner Trustee in connection with a request to pursue dispute resolution pursuant to this Section 9.24, the Owner Trustee shall act at the direction of the Certificateholders
holding the majority of the voting interests of such directing Certificateholders. For the avoidance of doubt, neither the Indenture Trustee nor the Owner Trustee is required to, nor intends to, exercise discretion with respect to any action
pursuant to this Section 9.24(a). 

  

					
		 	39	  	Sale and Servicing Agreement (SDART 2018-3)








 (b) The Requesting Party will provide notice in accordance with the provisions of
Section 9.6 of its intention to refer the matter to mediation or arbitration, as applicable, to Santander Consumer, with a copy to the Issuer, the Seller, the Owner Trustee and the Indenture Trustee. Santander Consumer
agrees that it will participate in the resolution method selected by the Requesting Party. Santander Consumer shall provide notice to the Seller, the Issuer, the Owner Trustee, and the Indenture Trustee that Santander Consumer has received a request
to mediate or arbitrate a repurchase request. Upon receipt of such notice, the Seller, the Issuer, the Owner Trustee (acting at the direction of a Certificateholder), and the Indenture Trustee (acting at the direction of a Noteholder or Note Owner)
shall advise the Requesting Party and Santander Consumer of an intent to join in the mediation or arbitration, which shall result in their being joined as a Requesting Party in the proceeding. A Requesting Party may not initiate a mediation or
arbitration pursuant to this Section 9.24 with respect to a Receivable that is, or has been, the subject of an ongoing or previous mediation or arbitration (whether by that Requesting Party or another Requesting Party) but
will have the right, subject to a determination by the parties to the existing mediation or arbitration that such joinder would not prejudice the rights of the participants to such existing mediation or arbitration or unduly delay such proceeding,
to join an existing mediation or arbitration with respect to that Receivable if the mediation or arbitration has not yet concluded. In the case of any such joinder, if the initial Requesting Party is (i) the Indenture Trustee (on behalf of one
or more Noteholders or Note Owners), any decisions related to the mediation or arbitration will be made by the Indenture Trustee at the written direction of the Requesting Investor holding a majority of the Note Balance of all of the Notes held by
such directing Noteholders and/or Note Owners, and (ii) the Owner Trustee (on behalf of one or more Certificateholders), any decisions related to the mediation or arbitration will be made by the Owner Trustee on behalf of the Certificateholders
holding the majority of the voting interests of the directing Certificateholders. 
 (c) If the Requesting Party selects mediation as the
resolution method, the following provisions will apply: 
 (i) The mediation will be administered by a nationally recognized
arbitration and mediation association selected by the Requesting Party pursuant to such association’s mediation procedures in effect at such time. 

(ii) The fees and expenses of the mediation will be allocated as mutually agreed by the parties as part of the mediation. 

(iii) The mediator will be impartial, knowledgeable about and experienced with the laws of the State of New York that are
relevant to the repurchase dispute and will be appointed from a list of neutrals maintained by the American Arbitration Association (the “AAA”). 

  

					
		 	40	  	Sale and Servicing Agreement (SDART 2018-3)








 (d) If the Requesting Party selects arbitration as the resolution method, the following
provisions will apply: 
 (i) The arbitration will be administered by a nationally recognized arbitration and mediation
association jointly selected by the parties, and if the parties are unable to agree on an association, by the AAA, and conducted pursuant to such association’s arbitration procedures in effect at such time. 

(ii) The arbitrator will be impartial, knowledgeable about and experienced with the laws of the State of New York that are
relevant to the dispute hereunder and will be appointed from a list of neutrals maintained by AAA. 
 (iii) The arbitrator
will make its final determination no later than 90 days after appointment or as soon as practicable thereafter. The arbitrator will resolve the dispute in accordance with the terms of this Agreement, and may not modify or change this Agreement in
any way. The arbitrator will not have the power to award punitive damages or consequential damages in any arbitration conducted by it, and Santander Consumer shall not be required to pay more than the applicable Repurchase Price with respect to any
receivable which Santander Consumer is required to repurchase under the terms of the Purchase Agreement or this Agreement, as applicable. In its final determination, the arbitrator will determine and award the costs of the arbitration (including the
fees of the arbitrator, cost of any record or transcript of the arbitration, and administrative fees) and reasonable attorneys’ fees to the parties as determined by the arbitrator in its reasonable discretion. The determination of the
arbitrator will be in writing and counterpart copies will be promptly delivered to the parties. The determination may be enforced in any court of competent jurisdiction. 

(iv) No person may bring a putative or certified class action to arbitration. 

(e) The following provisions will apply to both mediations and arbitrations: 

(i) Any mediation or arbitration will be held in New York, New York or such other location mutually agreed to by the Requesting
Party and Santander Consumer; 
 (ii) Notwithstanding this dispute resolution provision, the parties will have the right to
seek provisional relief from a competent court of law, including a temporary restraining order, preliminary injunction or attachment order, provided such relief would otherwise be available by law; and 

(iii) The details and/or existence of any unfulfilled repurchase request, any meetings or discussions regarding any unfulfilled
repurchase request, mediations or arbitration proceedings conducted under this Section 9.24, including all offers, promises, conduct and statements, whether oral or written, made in the course of the parties’ attempt
to resolve an unfulfilled repurchase request, any information exchanged in connection with any mediation, and any discovery taken in connection with any arbitration (collectively, “Confidential Information”), shall be and remain
confidential and inadmissible (except disclosures required by applicable law) for any purpose, including 

  

					
		 	41	  	Sale and Servicing Agreement (SDART 2018-3)








 
impeachment, in any mediation, arbitration or litigation, or other proceeding (including any proceeding under this Section 9.24) other than as required to be disclosed
in accordance with applicable law, regulatory requirements, or court order or to the extent that Santander Consumer, in its sole discretion, elects to disclose such information. Such information will be kept strictly confidential and will not be
disclosed or discussed with any third party, except that a party may disclose such information to its own attorneys, experts, accountants and other agents and representatives (collectively “Representatives”), as reasonably required
in connection with any resolution procedure under this Section 9.24, and to the Asset Representations Reviewer, if an Asset Review has been conducted, if the disclosing party (a) directs such Representatives to keep
the information confidential, (b) is responsible for any disclosure by its Representatives of such information and (c) takes at its sole expense all reasonable measures to restrain such Representatives from disclosing such information. If
any party receives a subpoena or other request for information from a third party (other than a governmental regulatory body) for Confidential Information, the recipient will promptly notify the other party and will provide the other party with the
opportunity to object to the production of its Confidential Information or seek other appropriate protective remedies, consistent with the applicable requirements of law and regulation. If, in the absence of a protective order, such party or any of
its representatives are compelled as a matter of law, regulation, legal process or by regulatory authority to disclose any portion of the Confidential Information, such party may disclose to the party compelling disclosure only the part of such
Confidential Information that is required to be disclosed. For the avoidance of doubt, if the Indenture Trustee is the Requesting Party, the Indenture Trustee may disclose Confidential Information with respect to an Asset Review to the Requesting
Investor which directed the Indenture Trustee in connection with such Asset Review. 
 SECTION 9.25 Cooperation with Voting.
Each of Santander Consumer, the Seller and the Issuer hereby acknowledges and agrees that it shall cooperate with the Indenture Trustee to facilitate any vote by the Instituting Noteholders pursuant to the terms of
Section 7.6 of the Indenture. 
 SECTION 9.26 EU Risk Retention. Santander Consumer hereby covenants
and agrees, in connection with the EU Retention Rules, on an ongoing basis, so long as any Notes remain Outstanding: 
 (a) Santander
Consumer, as “originator” for the purposes of the EU Retention Rules, will retain upon issuance of the Notes and on an ongoing basis a material net economic interest (the “Retained Interest”) of not less than 5% in the
securitization transaction described in the Prospectus, in the form of retention of a first loss tranche, in accordance with the text of option (d) of each of Article 405(1) of the EU CRR, Article 51(1) of the AIFM Regulation and Article 254(2)
of the Solvency II Regulation, by holding all the membership interest in the Seller (or one or more other wholly-owned special purpose subsidiaries of Santander Consumer), which in turn will retain a portion of the aggregate Percentage Interests of
the Certificates, such portion representing at least 5% of the aggregate nominal value of the Receivables; 

  

					
		 	42	  	Sale and Servicing Agreement (SDART 2018-3)








 (b) Santander Consumer will not (and will not permit the Seller or any of its other affiliates
to) sell, hedge or otherwise mitigate its credit risk under or associated with the Retained Interest, except to the extent permitted in accordance with the EU Retention Rules; 

(c) Santander Consumer will not change the manner in which it retains the Retained Interest while any of the Notes are outstanding, except
under exceptional circumstances in accordance with the EU Retention Rules; and 
 (d) Santander Consumer will provide ongoing confirmation of
Santander Consumer’s continued compliance with its obligations described in clauses (a), (b) and (c) above (i) in or concurrently with the delivery of each Servicer’s Certificate, (ii) on the occurrence of any Event of Default
and (iii) from time to time upon request by any Noteholder in connection with any material change in the performance of the Receivables or the Notes or any material breach of the Transaction Documents.
