 SALE AND SERVICING AGREEMENT, dated as of August 26, 2015 (as amended, supplemented or
otherwise modified and in effect from time to time, this “Agreement”), by and among SANTANDER DRIVE AUTO RECEIVABLES TRUST 2015-4, a Delaware statutory trust (the “Issuer”), SANTANDER DRIVE AUTO RECEIVABLES LLC, a
Delaware limited liability company, as seller (the “Seller”), SANTANDER CONSUMER USA INC., an Illinois corporation (“Santander Consumer”), as servicer (in such capacity, the “Servicer”), and WELLS

ARTICLE I

		  		  	Sale and Servicing Agreement (2015-4)









 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 applicable Originator to the Obligors, the Dealers 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
Representations and Warranties of the Seller as to each Receivable. On the date hereof, the Seller hereby makes the representations and warranties set forth on Schedule I to the Issuer and the Indenture Trustee as to the
Receivables sold, transferred, assigned and otherwise conveyed to the Issuer under this Agreement on which such representations and warranties the Issuer relies in acquiring the Receivables. The Seller hereby further represents and warrants that, as
to the Receivables sold, transferred, assigned and otherwise conveyed to the Issuer under this Agreement, each such Receivable was selected using selection procedures that were not known or intended by the Seller to be adverse to the Issuer. The
representations and warranties as to each Receivable shall survive the Grant of the Receivables by the Issuer to the Indenture Trustee pursuant to the Indenture. Notwithstanding any statement to the contrary contained herein or in any other
Transaction Document, the Seller shall not be required to notify any insurer with respect to any Insurance Policy obtained by an Obligor or to notify any Dealer about any aspect of the transaction contemplated by the Transaction Documents. 

SECTION 2.3 Repurchase Upon Breach. Upon discovery by or notice to any party hereto of a breach of any of the representations
and warranties set forth in Section 2.2 with respect to any Receivable at the time such representations and warranties were made which materially and adversely affects the interests of the Issuer or the Noteholders, the party discovering
such breach or receiving such notice shall give prompt written notice thereof to the other parties hereto; provided, that delivery of a Servicer’s Certificate shall be deemed to constitute prompt notice by the Servicer, the Seller and
the Issuer of such breach; provided, further, that the failure to give such notice shall not affect any obligation of the Seller hereunder. If the breach materially and adversely affects the interests of the Issuer or the Noteholders
in such Receivable, then the Seller shall either (a) correct or cure such breach or (b) repurchase such Receivable from the Issuer, in either case on the Business Day before the Payment Date following the end of the Collection Period which
includes the 60th day (or, if the Seller elects, an earlier date) after the date the Seller became aware or was notified of such breach. Any such 

  

					
		  	2	  	Sale and Servicing Agreement (2015-4)









 
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 Seller shall be at a price equal to the related Repurchase Price. In consideration for such repurchase, the Seller 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 repurchase, or earlier date, if elected by the Seller. Upon payment of such Repurchase Price by the Seller, 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 Seller to evidence such release,
transfer or assignment or more effectively vest in the Seller or its designee all of the Issuer’s and Indenture Trustee’s rights in any Receivable and related Transferred Assets repurchased pursuant to this Section 2.3. It is
understood and agreed that the right to cause the Seller to repurchase (or to enforce the obligations of Santander Consumer under the Purchase Agreement to repurchase) any Receivable as described above shall constitute the sole remedy respecting
such breach available to the Issuer and the Indenture Trustee. Neither the Owner Trustee nor the Indenture Trustee will have any duty to conduct an affirmative investigation as to the occurrence of any condition requiring the repurchase of any
Receivable pursuant to this Section 2.3. 
 SECTION 2.4 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 applicable 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 


  

					
		  	3	  	Sale and Servicing Agreement (2015-4)










	 	(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 due 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 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 Servicer as custodian of the Receivable Files; 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, breach of contract or negligence of the Indenture Trustee


  

					
		  	4	  	Sale and Servicing Agreement (2015-4)









 
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 due 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 2.4(d). 
 (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, in the same manner as the Indenture Trustee or such Noteholders 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. 
 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 

  

					
		  	5	  	Sale and Servicing Agreement (2015-4)









 
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 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. 
 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 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, (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 Section 3.6. The Servicer 

  

					
		  	6	  	Sale and Servicing Agreement (2015-4)









 
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. 

(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 

  

					
		  	7	  	Sale and Servicing Agreement (2015-4)









 
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. 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 Receivable 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 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 such breach shall give prompt written notice thereof to the other parties hereto; provided, that the delivery of a Servicer’s Certificate shall be deemed to constitute prompt notice by
the Servicer and the Issuer of such breach; 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 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 

  

					
		  	8	  	Sale and Servicing Agreement (2015-4)









 
Repurchase Price. In consideration for such repurchase, 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 repurchase (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 repurchased 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 executed by an Authorized Officer of the Servicer containing all information necessary to make the
payments, transfers and distributions pursuant to Sections 4.3 and 4.4 on such Payment Date, together with the written statements to be 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 Servicer Replacement Event. 

(a) So long as the Seller is filing any reports with respect to the Issuer under the Exchange Act, the Servicer will deliver to the Issuer,
with a copy to the Indenture Trustee, on or before March 30th of each year, beginning on March 30, 2016, an Officer’s Certificate, dated as of December 31 of the immediately
preceding year, providing such information as is required under Item 1123 of Regulation AB. 
 (b) The Servicer will deliver to the
Issuer, with a copy to the Indenture Trustee within five (5) Business 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) So long as the Seller is filing any reports with respect to the Issuer under the Exchange Act, the Servicer will deliver to the Issuer, on
or before March 30th of each year,

Regulation AB. 
 SECTION 3.10 Annual Registered Public Accounting Firm Attestation 

(a) So long as the Seller is filing any reports with respect to the Issuer under the Exchange Act, on or before March 30th of each year, beginning March 30, 2016, the Servicer shall cause a registered public accounting firm, which may also render other services to the Servicer or to its Affiliates, to furnish to
the Issuer, with a copy to the Indenture Trustee, each attestation report on assessments of compliance with the 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 in the future in use by servicers of comparable assets, or which otherwise comply with any rule, regulation, “no action” letter or similar guidance promulgated by the Commission. 

(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 expenses described in the
definition of Liquidation Proceeds) 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 shall also pay all fees and disbursements of the Indenture Trustee (in accordance with Section 6.7 of the Indenture), Owner Trustee (in accordance with
Section 8.1 of the Trust Agreement) and Administrator and organizational expenses of the Issuer. 
 SECTION 3.12
Back-up Servicing. In the event that Santander Consumer is the Servicer, and (i) the long-term unsecured debt rating by Moody’s of Banco Santander, S.A. falls below “Baa3” (a “Ratings Trigger Event”)
or (ii) Banco Santander, S.A. ceases to directly or indirectly own at least 50% of the common stock of Santander Consumer (an “Ownership Trigger Event”), Santander Consumer shall have in place a back-up servicing

respectively, unless it shall be acceptable to Moody’s at such time, or otherwise satisfy the Rating Agency Condition with respect to Moody’s, for Santander Consumer not to have in place a back-up servicing arrangement or to deviate from
such published criteria.

be required to deposit into the Collection Account an amount equal to the Collections received during any Collection Period until noon, New York City time, on the Business Day prior to the related Payment Date. The “Monthly Remittance

 ARTICLE V 

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: 

(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 or instrument to which the Seller is a party or by which its
properties are bound (other than violations of such laws, rules, regulations, indentures, agreements or instruments 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. 

  

					
		  	18	  	Sale and Servicing Agreement (2015-4)









 (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. 
 (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. 

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 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. 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. 
 (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 

  

					
		  	19	  	Sale and Servicing Agreement (2015-4)









 
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 third party benefit of those entitled to rely thereon and will survive the termination of this Agreement. 

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 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 or (B) stating that, in the opinion of such counsel, no such action shall be necessary to preserve and protect such interest. 

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. 

  

					
		  	20	  	Sale and Servicing Agreement (2015-4)









 
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. 
 SECTION 5.8 Perfection Representations,
Warranties and Covenants. The Seller hereby makes the perfection representations, warranties and covenants attached hereto as Exhibit B to the Issuer and the Indenture Trustee and the Issuer shall be deemed to have relied on such
representations, warranties and covenants in acquiring the Transferred Assets. 
 ARTICLE VI 

THE SERVICER 
 SECTION
6.1 Representations of Servicer. The Servicer 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: 

(a) Existence and Power. The Servicer is an Illinois corporation validly existing and in good standing under the laws of its state of
organization and has, in all material respects, full power and authority to own its assets and operate its business as presently owned or operated, and to execute, to deliver and to perform its obligations under the Transaction Documents to which it
is a party. The Servicer 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 Servicer 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 Servicer of the Transaction Documents to which it is a party have been duly authorized by all necessary action on the part of the Servicer 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 or instrument to which the Servicer is a party or by which its properties are bound, in
each case, other than violations of such laws, rules, regulations, organizational documents, indentures, agreements or instruments which do not affect 

  

					
		  	21	  	Sale and Servicing Agreement (2015-4)









 
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
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, (ii) approvals and authorizations
that have previously been obtained and filings that have previously been made or approvals, authorizations or filings that will be made on a timely basis and (iii) approval, authorizations or filings that, 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
against the Servicer 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 Servicer of its obligations under this
Agreement or any of the other Transaction Documents or (iv) relate to the Servicer that would materially and adversely affect the federal or Applicable Tax State income, excise, franchise or similar tax attributes of the Notes. 

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

  

					
		  	22	  	Sale and Servicing Agreement (2015-4)









 
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. 

(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 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. 

(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 of such Person as Servicer or a resignation by such Person as Servicer as well as the termination 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 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 the Servicer, 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. 

  

					
		  	23	  	Sale and Servicing Agreement (2015-4)









 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. 

SECTION 6.5 Delegation of Duties. The Servicer may, at any time without notice or 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


  

					
		  	24	  	Sale and Servicing Agreement (2015-4)









 
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, 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
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 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. 

  

					
		  	25	  	Sale and Servicing Agreement (2015-4)









 (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 be subject to all the responsibilities, duties and liabilities relating thereto, except with respect to the obligations of the predecessor Servicer that survive its termination as Servicer, including
indemnification obligations as set forth in Section 6.2(e). In such event, the Indenture Trustee and the Owner Trustee are hereby authorized and empowered to execute and deliver, on behalf of the predecessor Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such termination and replacement 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 compensation of the successor Servicer out
of Available Funds as it and such successor Servicer will agree; provided, however, that no such compensation will be in excess of the amount paid to the predecessor Servicer under this Agreement. 

SECTION 7.2 Notification to Noteholders. Upon any termination of, or appointment of a successor to, the Servicer pursuant to
this Article VII, the Indenture Trustee will give prompt written notice thereof to the Owner Trustee, the Issuer, the Administrator and to the Noteholders at their respective addresses of record. 

ARTICLE VIII 
 OPTIONAL
PURCHASE 
 SECTION 8.1 Optional Purchase of Trust Estate. The Servicer shall have the right at its option (the
“Optional Purchase”) to purchase the Trust Estate (other than the Reserve Account) from the Issuer on any Payment Date if both of the following conditions are satisfied: (i) as of the last day of the related Collection Period,
the Pool Balance has declined to 10% or less of the Pool Balance as of the Cut-Off Date and (ii) the sum of the Optional Purchase Price and the Available Funds for such Payment Date would be sufficient to pay (A) the Servicing Fee for such
Payment Date and all unpaid Servicing Fees with respect to prior periods, (B) interest then due on the Notes and (C) the aggregate unpaid Note Balance of all of the Outstanding Notes. To exercise such option, the Servicer shall deposit,
subject to Section 4.5, the Optional Purchase Price into the Collection Account on the Redemption Date. The Servicer shall furnish 

  

					
		  	26	  	Sale and Servicing Agreement (2015-4)









 
written notice of its election to exercise the Optional Purchase to the Indenture Trustee and the Owner Trustee not later than twenty days prior to date of the Optional Purchase. If the Servicer
exercises the Optional Purchase, the Notes shall be redeemed and in each case in whole but not in part on the related Payment Date for the Redemption Price. 

ARTICLE IX 

MISCELLANEOUS PROVISIONS 

SECTION 9.1 Amendment.

Noteholder, the Issuer, the Owner Trustee or any other Person subject to the satisfaction of one of the following conditions:

(b) This Agreement (including Appendix A) may also be amended from time to time by the Seller, the Servicer and the Indenture Trustee
(when so directed by an Issuer Request), with the consent of the Noteholders evidencing not less than a majority of the Note Balance of the Controlling Class, for the purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of the Noteholders; provided, that no such amendment shall (i) reduce the interest rate or principal amount of any Note or change or delay the Final Scheduled
Payment Date of any Note without the consent of the Holder of such Note or (ii) reduce the percentage of the aggregate outstanding principal balance of the Outstanding Notes, the consent of which is required to consent to any matter without the
consent of the Holders of at least the percentage of the Note Balance which was required to consent to such matter before giving effect to such amendment. It will not be necessary for the consent of Noteholders to approve the particular form of any
proposed amendment or consent, but it will be sufficient if such consent approves the substance thereof. The manner of obtaining such consents (and any other consents of Noteholders provided for in this Agreement) and of evidencing the authorization
of the execution thereof by Noteholders will be subject to such reasonable requirements as the Indenture Trustee may prescribe, including the establishment of record dates pursuant to the Depository Agreement. 

(c) Any term or provision of this Agreement (including Appendix A) may also be amended from time to time by the Seller and the

and the Servicer shall provide written notification of such amendment to the Indenture Trustee, the Issuer and the Owner Trustee and promptly after the execution of any such amendment, the Seller

 (d) Prior to the
execution of any such amendment, the Servicer shall provide written notification of the substance of such amendment to each Rating Agency and the Owner Trustee; and promptly after the execution of any such amendment, the Servicer shall furnish a
copy of such amendment to each Rating Agency, the Owner Trustee and the Indenture Trustee; provided, notwithstanding anything herein to the contrary, that no amendment pursuant to this Section 9.1 shall be effective which affects
the rights, protections or duties of the Indenture Trustee (including when performing its duties as Relevant Trustee) or the Owner Trustee without the prior written consent of such Person (which consent shall not be unreasonably withheld or
delayed). 
 (e) Prior to the execution of any amendment to this Agreement, the Owner Trustee and the Indenture Trustee (if the Indenture
Trustee is then the Relevant Trustee) shall be entitled to receive and conclusively rely upon an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement and that all conditions precedent to the
execution and delivery of such amendment have been satisfied. The Owner Trustee and the Indenture Trustee may, but shall not be obligated to, enter into or execute on behalf of the Issuer any such amendment which adversely affects the Owner
Trustee’s or the Indenture Trustee’s (including when performing its duties as Relevant Trustee), as applicable, own rights, duties or immunities under this Agreement. 

(f) Notwithstanding subsections (a) and (b) of this Section 9.1, this Agreement may only be amended by the
Seller and the Servicer if (i) the Majority Certificateholders consent to such amendment or (ii) such amendment shall not, as evidenced by an Officer’s Certificate of the Seller or the Servicer or an Opinion of Counsel delivered to
the Indenture Trustee and the Owner Trustee, materially and adversely affect the interests of the Certificateholders. 
 SECTION 9.2
Protection of Title. 
 (a) The Seller shall authorize and file such financing statements and cause to be authorized and filed
such continuation and other 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 Receivables (other than
any Related Security with respect thereto, to the extent that the interest of the Issuer or the Indenture Trustee therein cannot 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)
Neither the Seller nor the Servicer shall change its name, identity, organizational structure or jurisdiction of organization in any manner that would make any financing statement or continuation statement filed by the Seller in accordance with
paragraph (a) above “seriously misleading” within the meaning of Sections 9-506, 9-507 or 9-508 of the UCC, unless it (i) shall have given the Issuer and the Indenture Trustee at
least five days’ prior written notice thereof,

(ii) to the extent necessary, shall have promptly filed amendments to previously filed financing statements or continuation statements described in paragraph (a) above and
(iii) shall have delivered to the Indenture Trustee within 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 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 paragraph (a) above. 

(d) The Servicer shall maintain (or shall cause its Sub-Servicer to maintain) in accordance with its Customary Servicing Practices accounts
and records as to each Receivable accurately and in sufficient detail to permit (i) the reader thereof to know at any time the status of such Receivable, including payments and recoveries made and payments owing (and the nature of each) and
(ii) reconciliation between payments or recoveries on (or with respect to) each Receivable and the amounts from time to time deposited in the Collection Account in respect of such Receivable. 

(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 Issuer’s and the Indenture Trustee’s interest in a Receivable shall not be deleted from or modified on such
computer systems until, and only until, the related Receivable shall have been paid in full or repurchased. 
 (f) If at any time the
Servicer shall propose to sell, grant a security interest in or otherwise transfer any interest in motor vehicle receivables to any prospective purchaser, lender or other transferee, the Servicer shall give to such prospective purchaser, lender or
other transferee computer tapes, records or printouts (including any restored from backup archives) that, if they shall refer in any manner whatsoever to any Receivable, shall indicate clearly that such Receivable has been sold and is owned by the
Issuer and has been pledged to the Indenture Trustee on behalf of the Noteholders. 
 SECTION 9.3 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 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. 

  

					
		  	29	  	Sale and Servicing Agreement (2015-4)









 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: 
  

	 	(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 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
Issuer, the Seller or any of their Affiliates, in order to comply with or obtain more favorable treatment under any current or future law, rule, regulation, accounting rule or principle. 

  

					
		  	30	  	Sale and Servicing Agreement (2015-4)









 SECTION 9.6 Notices, Etc. All demands, notices and communications hereunder shall
be in writing and shall be delivered or mailed by registered or certified first-class United States mail, postage prepaid, hand delivery, prepaid courier service, or by facsimile or by electronic transmission, and addressed in each case as set forth
on Schedule II hereto or at such other address as shall be designated in a written notice to the other parties hereto. Any notice required or permitted to be mailed to a Noteholder shall be given by first class mail, postage prepaid, at
the address 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 prescribed in this Agreement shall be conclusively presumed to have been duly given, whether or not the Noteholder shall receive such
notice. 
 SECTION 9.7 Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL,
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. 
 SECTION 9.8
Headings. The section headings hereof have been inserted for convenience of reference only and shall not be construed to affect the meaning, construction or effect of this Agreement. 

SECTION 9.9 Counterparts. This Agreement may be executed in any number of counterparts, each of which so executed shall be
deemed to be an original, but all of such counterparts shall together constitute but one and the same instrument. 
 SECTION 9.10
Waivers. No failure or delay on the part of the Servicer, the Seller, the Issuer or the Indenture Trustee in exercising any power or right hereunder (to the extent such Person has any power or right hereunder) shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or the exercise of any other power or right. No notice to or demand on any party hereto in any case shall entitle it to any
notice or demand in similar or other circumstances. No waiver or approval by any party hereto under this Agreement shall, except as may otherwise be stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval
under this Agreement shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. 
 SECTION 9.11
Entire Agreement. The Transaction Documents contain a final and complete integration of all prior expressions by the parties hereto with respect to the subject matter thereof and shall constitute the entire agreement among the parties
hereto with respect to the subject matter thereof, superseding all prior oral or written understandings. There are no unwritten agreements among the parties.

agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this
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,
assignment and Grant of a security interest in the Receivables, the other Transferred Assets and the Issuer’s rights under this Agreement by the Issuer to the Indenture Trustee pursuant to the Indenture for the benefit of the Noteholders. In
addition, the Seller hereby acknowledges and agrees that for so long as the Notes are outstanding, the Indenture Trustee will have the right to exercise all powers, privileges and claims of the Issuer under this Agreement in the event that the
Issuer shall fail to exercise the same. 
 SECTION 9.15 Cumulative Remedies. The remedies herein provided are cumulative and
not exclusive of any remedies provided by law.

event permitting acceleration under the terms of the Receivable existed as of the Cut-Off Date or that any continuing condition that with notice or lapse of time, or both, would constitute a default, breach, violation or event permitting
acceleration under the terms of the Receivable had arisen as of the Cut-Off Date and the Seller has not waived any of the foregoing. 

  

	(g)	Insurance. The Receivable requires that the Obligor thereunder obtain comprehensive and collision insurance covering the related Financed Vehicle. 


 

	(h)	No Government Obligor. The Obligor on the Receivable is not the United States of America or any state thereof or any local government, or any agency, department, political subdivision or instrumentality of the
United States of America or any state thereof or any local government. 

  

	(i)	Assignment. No Receivable has been originated in, or is subject to the laws of, any jurisdiction under which the sale, transfer, assignment, setting over, conveyance or pledge of such Receivable would be
unlawful, void, or voidable. Santander Consumer has not entered into any agreement with any Obligor that prohibits, restricts or conditions the assignment of the related Receivable. 


 

	(j)	Good Title. It is the intention of the Seller that the sale, contribution, transfer, assignment and conveyance herein contemplated constitute an absolute sale, contribution, transfer, assignment and conveyance of
the Receivables and that the Receivables not be part of the Seller’s estate in the event of the filing of a bankruptcy petition by or against the Seller under any bankruptcy law. As of the Closing Date, no Receivable has been sold, contributed,
transferred, assigned, conveyed or pledged to any Person other than pursuant to the Transaction Documents. As of the Closing Date and immediately prior to the sale and transfer contemplated in the Sale and Servicing Agreement, the Seller had good
and marketable title to and was the sole owner of each Receivable free and clear of all Liens (except any Lien which will be released prior to assignment of such Receivable hereunder), and, immediately upon the sale and transfer thereof, the Issuer
will have good and marketable title to each Receivable, free and clear of all Liens (other than Permitted Liens). 

  

	(k)	Filings. All filings (including, without limitation, UCC filings) necessary in any jurisdiction to give the Issuer a first priority, validly perfected ownership interest in the Receivables (other than any Related
Security with respect thereto, to the extent that an ownership interest therein cannot be perfected by the filing of a financing statement), and to give the Indenture Trustee a first priority perfected security interest therein, will be made within
ten days of the Closing Date. 


  

					
		  	I-3	  	 Schedule I to the

Sale and Servicing Agreement











	(l)	Priority. The Receivable is not pledged, assigned, sold, subject to a security interest, or otherwise conveyed other than pursuant to the Transaction Documents. The Seller has not authorized the filing of and is
not aware of any financing statements against the Originator or 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 Receivable hereunder, will be terminated, amended or released. The Sale and Servicing Agreement creates a valid and continuing security interest in the Receivable (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. 

  

	(m)	Characterization of Receivables. Each Receivable constitutes either “tangible chattel paper,” an “account,” an “instrument,” or a “general intangible,” each as defined in
the UCC. 

  

	(n)	One Original. There is only one executed original copy of the Contract (in each case within the meaning of the UCC) related to each Receivable. 


 

	(o)	No Defenses. The Seller has no knowledge either of any facts which would give rise to any right of rescission, offset, claim, counterclaim or defense, or of the same being asserted or threatened, with respect to
any Receivable.
