(a) If any Receivable is subject to repurchase pursuant to Section 6.01 or Section 6.02 of this Agreement, which
repurchase is not resolved in accordance with the terms of this Agreement within 180 days after notice is delivered to Capital One as specified in any such Section, the party providing such notice (the “Requesting Party”) will have

 (iv) The fees and expenses
of the mediation will be allocated as mutually agreed by the Requesting Party and the Representing Party as part of the mediation. 

(v) A failure by the Requesting Party and the Representing Party to resolve a disputed matter through mediation shall not
preclude either party from seeking a resolution of such matter through the initiation of a judicial proceeding in a court of competent jurisdiction, subject to subsection 6.03(d) below. 

(c) If the Requesting Party selects arbitration as the resolution method, the following provisions will apply: 

(i) The arbitration will be held in accordance with the United States Arbitration Act, notwithstanding any choice of law
provision in this Agreement, and under the auspices of the AAA and in accordance with the Rules.

(iii) If the repurchase request specified in subsection 6.03(a) involves the repurchase of an aggregate amount of
Receivables equal to or in excess of $[            ], a three-arbitrator panel will be used. The arbitral panel will consist of three Qualified Dispute Resolution Professionals,
(A) one to be appointed by the Requesting Party within five Business Days of providing notice to the Representing Party of its selection of arbitration, (B) one to be appointed by the Representing Party within five Business Days of the
Requesting Party’s appointment of an arbitrator, and (C) the third, who will preside over the arbitral panel, to be chosen by the two party-appointed arbitrators within five Business Days of the Representing Party’s appointment. If
any party fails to appoint an arbitrator or the two party-appointed arbitrators fail to appoint the third within the relevant time periods, then the appointments will be made by the AAA pursuant to the Rules. 

(iv) Each arbitrator selected for any arbitration will abide by the Code of Ethics for Arbitrators in Commercial Disputes in
effect at the time the arbitration is initiated. Prior to accepting an appointment, each arbitrator must promptly disclose any circumstances likely to create a reasonable inference of bias or conflict of interest or likely to preclude completion of

 (v) The Requesting Party and the Representing Party each agree that it is their
intention that after consulting with the parties, the arbitrator or arbitral panel, as applicable, will devise procedures and deadlines for the arbitration, to the extent not already agreed to by the parties, with the goal of expediting the
proceeding and completing the arbitration within [        ] days after appointment of the arbitrator or arbitral panel, as applicable. The arbitrator or the arbitral panel, as applicable, will have the

(30) calendar days of the making of a request. Additional depositions may be scheduled only with the permission of the arbitrator or arbitral panel, and for good cause shown. Each deposition shall be limited to a maximum of three
(3) hours’ duration. All objections are reserved for the arbitration hearing except for objections based on privilege and proprietary or confidential information. 

(C) Any dispute regarding discovery, or the relevance or scope thereof, shall be determined by the arbitrator or arbitral
panel, which determination shall be conclusive. 
 (D) All discovery shall be completed within sixty (60) calendar days
following the appointment of the arbitrator or the arbitral panel, as applicable; provided, that the arbitrator or the arbitral panel, as applicable, will have the ability to grant the parties, or either of them, additional discovery to the

 -4- 








 (vi) The Requesting Party and the Representing Party each agree that it is their
intention that the arbitrator or the arbitral panel, as applicable, will resolve the dispute in accordance with the terms of this Agreement, and may not modify or change this Agreement in any way. The arbitrator or the arbitral panel, as applicable,
will not have the power to award punitive damages or consequential damages in any arbitration conducted. The Requesting Party and the Representing Party each agree that it is their intention that in its final determination, the arbitrator or the
arbitral panel, as applicable, will determine and award the costs of the arbitration (including the fees of the arbitrator or the arbitral panel, as applicable, cost of any record or transcript of the arbitration, and administrative fees) and
reasonable attorneys’ fees to the parties as determined by the arbitrator or the arbitral panel, as applicable, in its reasonable discretion. The determination of the arbitrator or the arbitral panel, as applicable, must be consistent with the
provisions of this Agreement, including Section 9.06 (with the understanding that any costs allocated to Funding under this subsection 6.03(c)(vi) will be limited as though such costs were claims of Capital One for purposes of
Section 9.06), and will be in writing and counterpart copies will be promptly delivered to the parties. The determination of the arbitrator or the arbitral panel, as applicable, may be reconsidered once by the arbitrator or the arbitral
panel, as applicable, upon the motion and at the expense of either party. Following that single reconsideration, the determination of the arbitrator or the arbitral panel, as applicable, will be final and non-appealable and may be entered in and may
be enforced in, any court of competent jurisdiction. 
 (vii) By selecting arbitration, the Requesting Party is giving up
the right to sue in court, including the right to a trial by jury. 
 (viii) No Person may bring a putative or certified
class action to arbitration. 
 (d) The following provisions will apply to both mediations and arbitrations: 

(i) Any mediation or arbitration will be held in New York, New York. 

(ii) Notwithstanding this dispute resolution provision, the parties will have the right to seek provisional or ancillary
relief from a competent court of law, including a temporary restraining order, preliminary injunction or attachment order, provided such relief would otherwise be available by law. 

(iii) The details and/or existence of any unfulfilled repurchase request specified in subsection 6.03(a) above, any
informal meetings, mediations or arbitration proceedings, including all offers, promises, conduct and statements, whether oral or written, made in the course of the parties’ attempt to informally resolve an unfulfilled repurchase request, and
any discovery taken in connection with any arbitration, will be confidential, privileged and inadmissible for any purpose, including impeachment, in any mediation, arbitration or litigation, or other proceeding; provided, however, that any discovery
taken in any arbitration will be admissible in that particular arbitration. Such information will be kept strictly confidential and will not be disclosed or discussed with any third party (excluding a party’s attorneys, experts,


  
 -5- 








 
accountants and other agents and representatives, as reasonably required in connection with the related resolution procedure), except as otherwise required by law, regulatory requirement or court
order. If any party to a resolution procedure receives a subpoena or other request for information from a third party (other than a governmental regulatory body) for such confidential information, the recipient will promptly notify the other party
to the resolution procedure and will provide the other party with the opportunity to object to the production of its confidential information. Notwithstanding anything in this Section 6.03 to the contrary, any discovery taken in
connection with any arbitration pursuant to subsection 6.03(c) above will be admissible in such arbitration.
