 ARTICLE II 

PURCHASE 
 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 (i) all of the Notes and (ii) the Certificates on the Closing Date, the Seller does hereby sell,
transfer, assign, set over, sell and otherwise convey to the Issuer without recourse (subject to the obligations herein) on the Closing Date all of its right, title, interest, claims and demands, 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 (the “Assignment”) 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. 
 ARTICLE III 

REPRESENTATIONS, WARRANTIES AND COVENANTS 

SECTION 3.1 Representations and Warranties of the 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: 
 (a) Existence and Power. The
Seller is a limited liability company validly existing and in good standing under the laws of the State of Delaware and has, in all material respects, all power and authority to carry on its business as it is now conducted. 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 this Agreement 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 this Agreement (i) have been duly authorized by all necessary limited liability company action on the part of the Seller and (ii) do not contravene or constitute a default under (A) any applicable order,
law, rule or regulation, (B) its organizational documents or (C) any material agreement, contract, order or other instrument to which it is a party or its property is subject (other than violations which do not affect the legality,
validity or enforceability of such agreements or 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, this Agreement).

 (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 this Agreement 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 this Agreement. 

  

					
		  	-2-	  	COPAR 2021-1 Sale Agreement

 (d) Binding Effect. This Agreement 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) No Proceedings. There are no 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 (ii) seek any determination or ruling that would materially and adversely affect the performance by the Seller of its obligations under this
Agreement. 
 (f) Lien Filings. The Seller is not aware of any material judgment, ERISA or tax lien filings against the Seller. 

SECTION 3.2 Representations and Warranties of the Seller Regarding the Transferred Assets. On the date hereof, the Seller hereby makes
the following representations and warranties to the Issuer, on which the Issuer will be deemed to have relied in acquiring the Transferred Assets: 

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

(b) 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 created by the Seller (other than Permitted Liens) and is enforceable as such against all other creditors of and purchasers and assignees from the Seller. 

(c) The representations and warranties regarding creation, perfection and priority of security interests in the Transferred Assets, which are
attached to this Agreement as Schedule II, are true and correct. 
 SECTION 3.3 Liability of the Seller. 

(a) The Seller shall be liable in accordance herewith only to the extent of the obligations specifically undertaken by the Seller under this
Agreement. 

  

					
		  	-3-	  	COPAR 2021-1 Sale Agreement

 (b) The Seller shall indemnify, defend, and hold harmless the Issuer, the Owner Trustee and
the Indenture 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. 
 (c) Indemnification under this Section 3.3 will survive the resignation or removal of
the Owner Trustee or the Indenture Trustee and the termination or assignment 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 3.3 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. 

(d) The Seller’s obligations under this Agreement and the other Transaction Documents 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 in, claim to or benefit in or from Other Assets or (ii) is deemed to have any such interest in, 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 further acknowledges and agrees that any such interest in, claim to 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 3.3(d) and the terms of this
Section 3.3(d) may be enforced by an action for specific performance. The provisions of this Section 3.3(d) will be for the third-party benefit of those entitled to rely thereon and will survive
the termination of or the assignment of this Agreement, and the resignation or removal of any indemnified party. Any amounts payable to the Indenture Trustee pursuant to this Section 3.3(d), to the extent not paid by the
Seller, shall be paid by the Issuer in accordance with Section 8.5(a) of the Indenture. 

  

					
		  	-4-	  	COPAR 2021-1 Sale Agreement

 SECTION 3.4 Merger or Consolidation of, or Assumption of the Obligations of, Seller.
Any Person (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, (ii) resulting from any merger, sale,
transfer, conversion, or consolidation to which the Seller shall be a party, (iii) succeeding to the business of the Seller, or (iv) 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 Capital One Financial Corporation, which Person in any of the foregoing cases executes an agreement of assumption to perform every obligation of the Seller under this Agreement, will be the successor to the Seller under
this Agreement without the execution or filing of any document or any further act on the part of any of the parties to this Agreement anything herein to the contrary notwithstanding. The Seller shall provide notice of any merger, conversion,
consolidation or succession pursuant to this Section 3.5 to the Administrator. Notwithstanding the foregoing, if the Seller enters into any of the foregoing transactions and is not the surviving entity, the Seller will
deliver to the Indenture Trustee and the Owner 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 and, if the Notes are Outstanding, the Indenture Trustee for the benefit of the Noteholders, respectively, in the Receivables, or (B) stating that, in the opinion of such counsel,
no such action is necessary to preserve and protect such interest. 
 SECTION 3.5 Seller May Own Notes and Certificates. The Seller,
and any Affiliate of the Seller, may in its individual or any other capacity become the owner or pledgee of Notes and Certificates 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 and Certificates 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 and Certificates. 

SECTION 3.6 Compliance with Organizational Documents. The Seller shall comply with its limited liability company agreement and other
organizational documents. 
 SECTION 3.7 Protection of Title. 

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

  

					
		  	-5-	  	COPAR 2021-1 Sale Agreement

 (b) The Seller shall notify the Issuer in writing within ten (10) days following the
occurrence of (i) any change in the Seller’s organizational structure as a limited liability company, (ii) any change in the Seller’s “location” (within the meaning of
Section 9-307 of the UCC) and (iii) any change in the Seller’s name, and shall take all action prior to making such change (or shall have made arrangements to take such action substantially
simultaneously with such change, if it is not practicable to take such action in advance) reasonably necessary or advisable in the opinion of the Issuer to amend all previously filed financing statements or continuation statements described in
paragraph (a) above. The Seller will at all times maintain its “location” within the United States. 
 (c) The Seller
shall maintain (or shall cause the 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 (or any subsequent assignee of the Issuer) in such Receivable and that such Receivable is owned by such Person. Indication of such Person’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. 

(d) If at any time the Seller 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 Seller 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 (or any subsequent assignee of the Issuer). 

SECTION 3.8 Other Liens or Interests. Except for the conveyances and grants of security interests pursuant to this Agreement and the
other Transaction Documents, the Seller shall not sell, pledge, assign or transfer the Receivables or other property transferred to the Issuer to any other Person, or grant, create, incur, assume or suffer to exist any Lien (other than Permitted
Liens) on any interest therein, and the Seller shall defend the right, title and interest of the Issuer in, to and under such Receivables or other property transferred to the Issuer against all claims of third parties claiming through or under the
Seller. 
 SECTION 3.9 Exchange Act Filings. The Issuer hereby authorizes the Seller to prepare, sign, certify and file any and all
reports, statements and information respecting the Issuer and/or the Notes required to be filed pursuant to the Exchange Act, and the rules thereunder. 

SECTION 3.10 Sarbanes-Oxley Act Requirements. To the extent any documents are required to be filed or any certification is required to
be made with respect to the Issuer or the Notes pursuant to the Sarbanes-Oxley Act, the Issuer hereby authorizes the Seller to prepare, sign, certify and file any such documents or certifications on behalf of the Issuer. 

SECTION 3.11 Compliance with the FDIC Rule. The Seller (i) shall perform the covenants set forth in Article XII of the
Indenture applicable to it and (ii) shall facilitate compliance with Article XII of the Indenture by the Capital One Parties. 

  

					
		  	-6-	  	COPAR 2021-1 Sale Agreement

 SECTION 3.12 Noteholder Communication. A Noteholder (if the Notes are represented by
Definitive Notes) or a Note Owner (if the Notes are represented by Book-Entry Notes) may send a request to the Seller at any time notifying the Seller that such Noteholder or Note Owner, as applicable, would like to 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 Owners, as
applicable, may contact the requesting Noteholder or Note Owner. A Noteholder or Note Owner, as applicable, that delivers a request under this Section 3.12 will be deemed to have certified to the Issuer, the Seller and the
Bank that its request to communicate with other Noteholders or Note Owners, as applicable, relates solely to a possible exercise of rights under the Indenture or the other Transaction Documents, and will not be used for other purposes. In each
monthly distribution report on Form 10-D under the Exchange Act with respect to the Issuer, the Seller shall include disclosure regarding any request that complies with the requirements of this
Section 3.12 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 applicable, stating that such Noteholder or Note Owner, as applicable, is interested in communicating with
other Noteholders or Note Owners, as applicable, with regard to the possible exercise of rights under the Transaction Documents, and (z) a description of the method other Noteholders or Note Owners, as applicable, may use to contact the
requesting Noteholder or Note Owner. The Seller and the Servicer will be responsible for any expenses incurred in connection with the filing of such disclosure and the reimbursement of any costs incurred by the Indenture Trustee in connection with
the preparation thereof. 
 ARTICLE IV 

MISCELLANEOUS 
 SECTION 4.1
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 and assignments 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 the 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 the 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 collectibility of the Receivables. 

  

					
		  	-7-	  	COPAR 2021-1 Sale Agreement

 (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 its agent of the Receivable Files and any other property that constitute instruments, money, negotiable documents or chattel paper shall be deemed to be “possession by the secured party” or possession by the purchaser or a
Person designated by such purchaser, for purposes of perfecting such 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 4.2 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 e-mail (if an applicable e-mail address is provided on Schedule I hereto), and addressed in each case as specified on Schedule I, or at such other address as shall be designated by any of the specified addressees in a written
notice to the other parties hereto. Any notice required or permitted to be mailed to a Noteholder or Certificateholder shall be given by first class mail, postage prepaid, at the address of such Noteholder or Certificateholder 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 or Certificateholder mailed within the time and manner prescribed in this Agreement shall be conclusively presumed to have been duly given, whether or not the Noteholder or Certificateholder shall
receive such notice. 
 SECTION 4.3 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 4.4 Headings. The section headings hereof have been inserted for convenience
only and shall not be construed to affect the meaning, construction or effect of this Agreement. 
 SECTION 4.5 Counterparts. This
Agreement may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, regardless of whether delivered in physical or electronic form, but all of such counterparts shall together constitute but one and
the same instrument. 
 SECTION 4.6 Amendment. 

(a) Any term or provision of this Agreement (including Appendix A hereto) may be amended by the Seller without the consent of the
Indenture Trustee, any Noteholder, the Owner Trustee or any other Person subject to the satisfaction of one of the following conditions: 

(i) The Seller delivers an Opinion of Counsel or an Officer’s Certificate to the Indenture Trustee to the effect that such
amendment will not materially and adversely affect the interests of the Noteholders; or 
 (ii) The Rating Agency Condition
is satisfied with respect to such amendment and the Seller notifies the Indenture Trustee in writing that the Rating Agency Condition is satisfied with respect to such amendment. 

(b) This Agreement (including Appendix A) may also be amended from time to time by the Issuer and the Seller, with the consent of the
Holders of Notes evidencing not less than a majority of the Outstanding 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 or the Certificateholders. It will not be necessary for the consent of Noteholders or Certificateholders 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 and Certificateholders provided for in this Agreement) and of evidencing the authorization of the execution
thereof by Noteholders and Certificateholders will be subject to such reasonable requirements as the Indenture Trustee and Owner Trustee may prescribe, including the establishment of record dates pursuant to the Depository Agreement. 

(c) Prior to the execution of any amendment pursuant to this Section 4.6, the Seller shall provide written
notification of the substance of such amendment to each Rating Agency; and promptly after the execution of any such amendment, the Seller shall furnish a copy of such amendment to each Rating Agency, the Issuer, the Owner Trustee and the Indenture
Trustee; provided, that no amendment pursuant to this Section 4.6 shall be effective which materially and adversely affects the rights, protections or duties of the Indenture Trustee or the Owner Trustee without the
prior written consent of such Person. 
 (d) Prior to the execution of any amendment to this Agreement, the Owner Trustee and the Indenture
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 an Officer’s Certificate of the Seller or the Administrator that
all conditions precedent to the execution and delivery of such amendment have been satisfied. 

  

					
		  	-9-	  	COPAR 2021-1 Sale Agreement

 (e) Notwithstanding subsections (a) and (b) of this

custodian of the following documents or instruments with respect to each Receivable (but only to the extent applicable to such Receivable and only to the extent held in tangible paper or electronic form) (the “Receivable Files”):

  

	 	(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 credit application or a photocopy thereof to the extent held in paper form; 

 

	 	(iii)	 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 or hold Certificates of Title; and 

  

	 	(iv)	 any and all other documents that the Servicer keeps on file, in accordance with its Customary Servicing
Practices, relating to a Receivable, an Obligor or a Financed Vehicle (but only to the extent applicable to such Receivable and only to the extent held in tangible paper form or electronic form).

Indenture Trustee, as pledgee of the Issuer. In performing its duties as custodian, the Servicer shall act in accordance with its Customary Servicing Practices. Nothing herein will be deemed to require an initial review or any periodic review by the

documents or instruments included in 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 5.5). 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 held in
tangible form 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, which do not unreasonably interfere with the Servicer’s normal operations, at the respective offices of the Servicer; provided, however, that in the case of this clause
(c), an officer of the Bank must be present during any such visit or discussion. 
 (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, to the extent it does not unreasonably interfere with the Servicer’s normal operations. 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. The Servicer shall not be responsible for any loss
occasioned by the failure of the Indenture Trustee or its agent or designee to return any document or any delay in doing so.

and 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 including those incurred in connection with any action, claim or suit brought to enforce the Indenture Trustee’s right to indemnification; provided, however, that the Servicer as custodian will
not be liable (i) to the Indenture Trustee or to 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 2.1(d). The provisions of this Section 2.1(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. Any amount payable to the Indenture Trustee pursuant to this Section 2.1(f), to the extent
not paid by the Servicer, shall be paid by the Issuer in accordance with Section 8.5(a) of the Indenture.

Agreement or if all of the rights and obligations of the Servicer have been terminated under Section 6.1, the appointment of the Servicer as custodian hereunder may be terminated by the Indenture Trustee pursuant to the
Transaction Documents, or by the Noteholders evidencing not less than a majority of the Outstanding Note Balance of the Controlling Class (or, if the Notes are no longer Outstanding, by the Majority Certificateholders), in the same manner as the
Relevant Trustee or such Noteholders (or Certificateholders) may terminate the rights and obligations of the Servicer under Section 6.1. As soon as practicable after any termination of such appointment, the Servicer will
deliver to the successor custodian the Receivable Files and the related accounts and records maintained by the Servicer at such place or places as the successor custodian 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 2.1(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. No such termination or resignation shall be given effect until a successor custodian has assumed the duties as custodian hereunder and in the Transaction Documents. 

(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.

RECEIVABLES AND TRUST PROPERTY 

SECTION 3.1 Duties of Servicer. 

(a) The Servicer is hereby appointed and authorized by the Issuer to act as agent for the Issuer and in such capacity shall manage, service,
administer and make collections on the Receivables in accordance with its Customary Servicing Practices, subject to the provisions herein, using the degree of skill and care 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, pursuing delinquencies, providing invoices or other payment
information (which may be in electronic form) to Obligors, reporting any required tax information to Obligors and accounting for Collections. 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. There are no requirements under the Receivables or the Transaction
Documents for payments or disbursements to 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

		  	4	  	COPAR 2021-1 Servicing Agreement

 (b) Subject to the provisions of Section 3.2 and any other
provision in this Agreement restricting the Servicer or specifying obligations different from the Customary Servicing Practices, 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 as long as such activities will not result or cause the Issuer to be treated, for United States federal income tax purposes, as
an association (or a publicly traded partnership) taxable as a corporation or as other than a fixed investment trust described in Treasury Regulation section 301.7701-4(c) that is treated as a grantor trust
for United States federal income tax purposes. 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 such 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 Proceeding to enforce a Receivable or an Insurance Policy or to commence or participate in any other 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 Proceeding to enforce a Receivable, 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 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, reasonably requested by the Seller 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 6.1, and, in any case, in a manner which the successor Servicer 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. 

  

					
		  	5	  	COPAR 2021-1 Servicing Agreement

 (d) The Servicer shall not be required to maintain a fidelity bond or error and omissions
policy or 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. The Servicer
may grant Permitted Modifications, but not any other extension, deferral, amendment, modification, alteration, temporary reduction in payments or adjustment, 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 preceding the latest Final Scheduled Payment Date of any Notes issued
under the Indenture or (ii) reduces the Contract Rate or Outstanding Principal Balance with respect to any Receivable, in either case other than (A) as required by law or court order, at the direction of a regulatory authority, in
accordance with regulatory guidance or in accordance with the Servicer’s compliance procedures for complying with the Servicemembers Civil Relief Act and any similar applicable state law or (B) in connection with a modification, adjustment
or settlement in the event the Receivable becomes a Severely Distressed Receivable, it will promptly purchase such Receivable in the manner provided in Section 3.6; provided, further, that the Servicer shall
not make a modification described in the preceding clause (i) or (ii) that would trigger a purchase pursuant to Section 3.6 for the sole purpose of enabling the Servicer to purchase a Receivable from the Issuer. The
Servicer may in its discretion waive any late payment charge or any other fees that constitute Supplemental Servicing Fees and Reimbursements that may be collected in the ordinary course of servicing a Receivable. The Servicer is not required to
make any advances of funds or guarantees regarding collections, cash flows or distributions. Without limiting the foregoing, the Servicer and its Affiliates (each in its individual capacity and not on behalf of the Issuer) may engage in any
marketing practice or promotion or any sale of any products, goods or services, including Insurance Policy, 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. 
 “Permitted Modification” means an extension, deferral, alteration, amendment, modification, temporary
reduction in payment or adjustment to the terms of, or with respect to, any Receivable with respect to which at least one of the following conditions has been satisfied: 
  

	 	(i)	 any amendment, modification, alteration or adjustment, individually and collectively with any other amendment,
modification, alteration or adjustment proposed to be made with respect to the Receivable, is ministerial in nature (including, without limitation, any change to the due date for monthly payments that is not classified by the Servicer as an
extension); 

  

					
		  	6	  	COPAR 2021-1 Servicing Agreement

	 	(ii)	 any amendment, modification, alteration or adjustment, individually and collectively with any other amendment,
modification, alteration or adjustment that (A) is required by law, or (B) (i) is in accordance with the Servicer’s Customary Servicing Practices and (ii) is intended by the Servicer to comply with or respond to a law, government
regulation or government enforcement activity pertaining to the Receivables or classes of loans similar to the Receivables; 

  

	 	(iii)	 in the case of any extension or deferral, (A) the Obligor’s address is within a geographic area
determined by the President of the United States or the Governor of the applicable state to warrant individual, or individual and public, assistance from the federal government under the Robert T. Stafford Disaster Relief and Emergency Assistance
Act or similar state law, as the case may be, or (B) the Obligor is a United States federal or state government employee that is furloughed on account of a shutdown of such government occurring as a result of a lapse in annual appropriations;

  

	 	(iv)	 any amendment, modification, alteration or adjustment where (A) the Obligor is in payment default, the
Receivable is a Severely Distressed Receivable or in the judgment of the Servicer, in accordance with the Servicer’s Customary Servicing Practices, it is reasonably foreseeable that the Obligor will default (it being understood that the
Servicer may proactively contact any Obligor whom the Servicer believes may be at higher risk of a payment default under the related Receivable, and it being further understood that if the Obligor has notified the Servicer that the obligor has been
materially and adversely impacted by a natural disaster or public terror attack, then the Servicer may reasonably conclude that it is reasonably foreseeable that such Obligor will default) and (B) the Servicer believes that such amendment,
modification, alteration or adjustment is appropriate or necessary to preserve the value of the Receivable and to prevent the Receivable from going into default (or, where the Receivable is already in default, to prevent the Receivable from becoming
further impaired); or 

  

	 	(v)	 any other extension, deferral, amendment, modification, alteration, temporary reduction in payment, or
adjustment is (A) in accordance with the Servicer’s Customary Servicing Practices and (B) the Servicer has delivered an opinion to the Issuer and the Administrator to the effect that such extension, deferral, amendment, modification,
alteration, temporary reduction in payment or adjustment will not cause the Issuer to be treated, for United States federal income tax purposes, as an association (or a publicly traded partnership) taxable as a corporation or as other than a grantor
trust for United States federal income tax purposes. 

 (b) Notwithstanding anything in this Agreement to the contrary, the
Servicer may refinance any Receivable at the request of the Obligor by making a new loan to the related Obligor and depositing the full Outstanding Principal Balance of such Receivable into the Collection Account. The receivable created by such
refinancing shall not be the property of the Issuer. The Outstanding Principal Balance shall be treated for all purposes, including for United States federal income tax purposes, as a payoff of all amounts owed by the related Obligor with respect to
such Receivable. 

  

					
		  	7	  	COPAR 2021-1 Servicing Agreement

 (c) Nothing in any section of this Agreement shall be construed to prevent the Servicer from
implementing new programs, whether on an intermediate, pilot or permanent basis, or on a regional or nationwide basis, or from modifying its standards, policies and procedures as long as, in each case, such programs or modifications (i) would
be consistent with its Customary Servicing Practices and (ii) would not cause the Issuer to be treated, for United States federal income tax purposes, as an association (or a publicly traded partnership) taxable as a corporation or as other
than a grantor trust for United States federal income tax purposes. 
 SECTION 3.3 Realization Upon Receivables. 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 the Financed Vehicle securing any Receivable as to which the Servicer has determined
eventual payment in full is unlikely, unless it determines in its sole discretion that repossession will not increase the Liquidation Proceeds by an amount greater than the expense of such repossession, that the proceeds ultimately recoverable with
respect to such Receivable would be increased by forbearance or that repossessing such Financed Vehicle would otherwise not be consistent with the Servicer’s Customary Servicing Practices. The Servicer will follow such Customary Servicing
Practices as it deems necessary or advisable, which may include reasonable efforts to realize upon any recourse to any Dealer and selling the 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. In addition, the Servicer may from time to time (but is not
required to) sell any deficiency balance in accordance with its Customary Servicing Practices; provided, however, that (i) each sale must be made at a price equal to the fair market value of such deficiency balance in cash in
immediately available funds and (ii) such sale must be without recourse, representation or warranty by the Issuer (other than any representation or warranty regarding the absence of Liens, that the Issuer has good title to the deficiency
balance, or similar representation or warranty). 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 from a third party 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. 

  

					
		  	8	  	COPAR 2021-1 Servicing Agreement

 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 for 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 created by the Receivable 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, at the direction of a regulatory authority or in accordance
with regulatory guidance, the Servicer will not release the Financed Vehicle securing each such Receivable from the security interest granted by such Receivable in whole or in part except (a) 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, (b) in connection with repossession or (c) 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 with respect to any Receivable which materially and adversely affects the
interests of the Issuer, the Certificateholders or the Noteholders, the party discovering or receiving written notice of such breach shall give prompt written notice thereof to the other parties hereto; provided, that (i) delivery of a
Servicer’s Report which identifies that Receivables are being or have been purchased pursuant to this Section 3.6 shall be deemed to constitute prompt notice by the Servicer and the Issuer of such breach and
(ii) the Servicer or 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 hereunder. If the breach materially and adversely affects the interests of the Issuer, the Certificateholders or the Noteholders or if the Servicer
is required to purchase a Receivable pursuant to Section 3.2, then the Servicer shall either (a) correct or cure such breach, if applicable, or (b) purchase such Receivable from the Issuer, in either case on or
before the Payment Date following the end of the Collection Period which includes the sixtieth (60th) day (or, if the Servicer elects, an earlier date) after the date that the Servicer became
aware or was notified of such breach or obligation to repurchase, as applicable. Any such breach or failure will be deemed not to have a material and adverse effect if such breach or failure has not affected 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 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 11:00 a.m., New York City time on the date of such purchase, if such date is not a Payment Date or, if such date is a Payment Date, then prior to the close
of business on the Business Day prior to such date. Upon payment of such Repurchase Price by the Servicer, the Issuer and the Indenture Trustee, on behalf of the Noteholders, shall release and shall execute and deliver such instruments of release,
transfer or assignment, in each case without recourse or representation and as prepared by and at the expense of the Servicer, as shall be reasonably necessary to vest in the Servicer or its designee any Receivable and the related Transferred Assets
purchased pursuant hereto. 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.

the Servicer shall not be required to maintain any investor record relating to the posting of disbursements or otherwise.

(a) Existence and Power. The Servicer is a national banking association validly existing under the laws of the United States of America
and has, in all material respects, all power and authority to carry on its business as it is now conducted. The Servicer has obtained all necessary licenses and approvals in each jurisdiction where the failure to do so would materially and adversely

(b) Authorization and No Contravention. The execution, delivery and performance by the Servicer of this Agreement (i) have been
duly authorized by all necessary action on the part of the Servicer and (ii) do not contravene or constitute a default under (A) any applicable order, law, rule or regulation, (B) its organizational documents or (C) any material
agreement, contract, order or other instrument to which it is a party or its property is subject (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 or 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, this Agreement). 

(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 this Agreement other than (i) UCC filings, (ii) approvals and authorizations that have previously been obtained and filings that have previously been made and (iii) approvals,

obligations under this Agreement. 
 (d) Binding Effect. This Agreement 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 the

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 United States 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. Any amounts payable to the Indenture Trustee pursuant to this Section 5.2(b), to the extent not paid by the Servicer, shall be paid by the Issuer in accordance with Section 8.5(a) of the Indenture. 

(c) The Servicer will indemnify, defend and hold harmless the Issuer, the Owner Trustee, the Indenture 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 repurchase of the affected Receivables is specified as the sole remedy pursuant to Section 3.6.

 (d) The Servicer will compensate and indemnify the Owner Trustee to the extent and subject
to the conditions set forth in Sections 8.1 and 8.2 of the Trust Agreement. The Servicer will compensate and indemnify the Indenture Trustee to the extent and subject to the conditions set forth in Section 6.7
of the Indenture, except 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 5.2 by the Bank (or any successor thereto pursuant to
Section 6.1), 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 or
assignment of this Agreement and the Trust Agreement or the resignation or removal of the Owner Trustee or the Indenture Trustee and will include reasonable fees and expenses of counsel and expenses of litigation and those amounts incurred in
connection with any action, claim or suit brought by the Indenture Trustee or the Owner Trustee to enforce its right to indemnification. If the Servicer 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 Servicer, without interest. 

SECTION 5.3 Merger or Consolidation of, or Assumption of the Obligations of, Servicer. Any Person (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, (ii) resulting from any merger, sale, transfer conversion or consolidation to which
the Servicer shall be a party, (iii) succeeding to the business of the Servicer or (iv) 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 Capital One
Financial Corporation, which Person in any of the foregoing cases executes an agreement of assumption to perform every obligation of the Servicer under this Agreement, will be the successor to the Servicer under this Agreement without the execution
or filing of any document or any further act on the part of any of the parties to this Agreement anything herein to the contrary notwithstanding. The Servicer shall provide prior notice of the effective date of any merger, conversion, consolidation
or succession pursuant to this Section 5.3 to the Issuer, the Indenture Trustee, the Owner Trustee and the Seller. The Servicer shall provide the Seller in writing such information as reasonably requested by the Seller to
comply with its Exchange Act reporting obligations with respect to a successor Servicer. 
 SECTION 5.4 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 in Section 5.2 of this Agreement and as otherwise provided under this Agreement, 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 5.5 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 and the Indenture Trustee for its duties hereunder as if the Servicer alone were performing such duties. 

SECTION 5.6 The Bank Not to Resign as Servicer. Subject to the provisions of Sections 5.3 and 5.5, the Bank 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 the Bank will be communicated to the Issuer, the Indenture Trustee and Owner 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, the Indenture Trustee and Owner Trustee concurrently with or promptly after such notice. No such resignation
will become effective until a successor Servicer has (i) assumed the responsibilities and obligations of the Bank as Servicer and (ii) provided in writing the information reasonably requested by the Seller to comply with its reporting
obligations under the Exchange Act with respect to a replacement Servicer. 
 SECTION 5.7 Servicer May Own Notes and Certificates.
The Servicer, and any Affiliate of the Servicer, may, in its individual or any other capacity, become the owner or pledgee of Notes and Certificates 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 and Certificates 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 Noteholders and Certificateholders.

 ARTICLE VI 

REPLACEMENT OF SERVICER 
 SECTION
6.1 Replacement of Servicer. 
 (a) If a Servicer Replacement Event shall have occurred and be continuing, the Relevant Trustee shall,
at the direction of 662⁄3% of the Outstanding Note Balance of the Controlling Class (or, if no Notes are Outstanding, the Majority Certificateholders), by notice
given to the Servicer, the Owner Trustee, the Issuer, the Administrator, the Certificateholders 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, acting at the direction of 662⁄3% of the Outstanding Note
Balance of the Controlling Class (or, if no Notes are Outstanding, the Majority Certificateholders), shall appoint a successor Servicer. Upon the Servicer’s receipt of notice of termination the predecessor 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 predecessor 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 in its sole discretion, 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 Outstanding 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 to have been cured and 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 to effect the orderly and efficient transfer of the
servicing of the Receivables to a successor Servicer. All reasonable costs and expenses incurred in connection with transferring the Receivable Files to the successor Servicer and all other reasonable costs and expenses incurred in connection with
the transfer to the successor Servicer related to the performance by the Servicer hereunder will be paid by the predecessor Servicer upon presentation of reasonable documentation of such costs and expenses. 

  

					
		  	17	  	COPAR 2021-1 Servicing Agreement

 (d) Upon the effectiveness of the assumption by the successor Servicer of its duties
pursuant to this Section 6.1, 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 5.2(e). In such event, the Indenture Trustee and the Owner Trustee are hereby authorized and empowered (but not obligated) 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. 

(e) In connection with such appointment, the Issuer 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 6.2 Notification to Noteholders and Certificateholders. Upon any termination of, or appointment of a successor to, the Servicer
pursuant to this Article VI, the Indenture Trustee will give prompt (but in no case later than five (5) Business Days after such occurrence) written notice thereof to the Owner Trustee, the Issuer and the Administrator, the Asset
Representations Reviewer and to the Noteholders and Certificateholders at their respective addresses of record. 
 ARTICLE VII 

OPTIONAL PURCHASE 
 SECTION 7.1
Optional Purchase of Trust Estate. The Servicer shall have the right at its option (the “Optional Purchase”) to purchase (and/or to designate one or more other Persons 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: (a) as of the last day of the related Collection Period, the Net Pool Balance has declined to 10% or less of the Net Pool Balance as of the Cut-Off Date; and (b) the sum of the Optional Purchase Price and Available Funds for such Payment Date would be sufficient to pay (x) the amounts required to be paid under clauses first
through ninth and eleventh of Section 8.5(a) of the Indenture (assuming that such Payment Date is not a Redemption Date) and (y) the Outstanding Note Balance (after giving effect to the
payments described in the preceding clause (x)). The purchase price for the Trust Estate (other than the Reserve Account) (the “Optional Purchase Price”) shall equal the Net Pool Balance plus accrued and unpaid interest on the
Receivables as of the last day of the Collection Period immediately preceding the Redemption Date, which amount (net of any Collections deposited into the Collection Account after the last day of the Collection Period immediately preceding the
Redemption Date) shall be deposited by the Servicer (or its designee) into the Collection Account on or prior to noon, New York City time, on the Redemption Date. If the Servicer (or its designee), 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.

manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Noteholders or the Certificateholders. It will not be necessary for the consent of Noteholders or Certificateholders to approve the

Section 8.1, this Agreement may only be amended by the Servicer if (i) the Majority Certificateholders or, if 100% of the aggregate Percentage Interests is then beneficially owned by the Bank and/or its Affiliates,

the certification provided by the Indenture Trustee pursuant to such clause in signing a Sarbanes Certification and filing such with the Commission. The Indenture Trustee further acknowledges that interpretations of the requirements of Regulation AB
may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants in the asset-backed securities markets, advice of counsel, or otherwise, and agrees to cooperate with the Seller to
deliver to the Seller and the Servicer such information necessary in the good faith determination of the Seller or the Servicer to permit the Seller or the Servicer, as applicable, to comply with the provisions of Regulation AB. 

(c) The Indenture Trustee shall provide the Seller and the Servicer (each, a “Transaction Party” and, collectively, the

Exchange Act nor shall it have any responsibility for making any filing to be made by a securitizer under the Exchange Act or Regulation AB. The Transaction Parties hereby acknowledge and agreed that the Indenture Trustee’s reporting is limited
to information that it has received or acquired solely in its capacity as indenture trustee under this Agreement and the Indenture and not in any other capacity. The Transaction Parties further hereby acknowledge and agree that, other than any
express duties or responsibilities as trustee under the Transaction Documents, the Indenture Trustee has no duty or obligation to undertake any investigation or inquiry related to repurchase demand activity in connection with any Transaction
Documents, and no obligations or duties are otherwise implied by this section.

knowledge of any such event to the extent that it relates to the Indenture Trustee or any action or failure to act by the Indenture Trustee. 

SECTION 8.21 Cooperation with Voting. Each of the Servicer 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 8.22 EU Risk Retention. The Bank hereby covenants and agrees, in connection with the EU Securitization Regulation and the UK
Securitization Regulation, in each case as in effect and applicable on the Closing Date, on an ongoing basis, so long as any Notes remain Outstanding: 

(a) The Bank, as “originator” (as such term is defined for the purposes of each of the Securitization Regulations), 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 at least 5% of
the nominal value of each of the tranches sold or transferred to investors in accordance with the text of

option (a) of Article 6(3) of the EU Securitization Regulation and option (a) of Article 6(3) of the UK Securitization Regulation, by holding (i) at least 5% of the nominal value
of each Class of Notes and (ii) all the membership interest in the Seller (or one or more other wholly-owned special purpose subsidiaries of the Bank), which in turn will hold at least 5% of the nominal value of the Certificates; 

(b) The Bank will not (and will not permit the Seller or any of its other affiliates to) hedge or otherwise mitigate its credit risk under or
associated with the Retained Interest, or sell, transfer or otherwise surrender all or part of the rights, benefits or obligations arising from the Retained Interest, except, in each case, to the extent permitted by the SR Rules; 

(c) The Bank will not change the manner or form in which it retains the Retained Interest while any of the Notes are outstanding, except as
permitted by the SR Rules; and 
 (d) The Bank will provide ongoing confirmation of its continued compliance with its obligations described
in the foregoing clauses (a), (b) and (c), in or concurrently with the delivery of each Servicer’s Report.
