CONVEYANCE OF RECEIVABLES 

Section 2.1 Contribution and Sale. 

(a) In consideration of Discover Funding’s payment of each related Purchase Price, and/or in consideration of the membership interest in
Discover Funding held by Discover Bank, Discover Bank hereby sells and assigns and/or contributes, as applicable, to Discover Funding, without recourse, all of Discover Bank’s right, title and interest in, to, and under (i) the Receivables
existing on the Effective Date (including the Existing Assets) and arising after the Effective Date in each Initial Account (including any related Surviving Account), and the Receivables existing on the related Additional Account Cut-Off Date and
arising after the related Additional Account Cut-Off Date in each Additional Account (including any related Surviving Account), (ii) all Interchange allocable to those Receivables, (iii) all Collections on those Receivables, including all
Recovered Amounts, and (iv) all proceeds of any of this property (collectively, the “Conveyed Assets”). Discover Funding hereby accepts the Conveyed Assets sold and/or contributed under this Agreement. The sale or contribution
of the Existing Assets pursuant to this Section 2.1(a) is subject to any rights in the Existing Assets transferred, assigned, set over or otherwise conveyed to the Trustee pursuant to the Prior PSA. 

  
 8 

 (b) In connection with such conveyance, Discover Bank further agrees, at its own expense, on or
prior to the Effective Date with respect to the Initial Accounts and on or prior to the Addition Date with respect to Additional Accounts to (i) indicate in its computer files that Receivables created in connection with the Accounts have been
transferred to Discover Funding pursuant to this Agreement and further transferred to DCMT for the benefit of the Certificateholders under the Pooling and Servicing Agreement by identifying the Accounts in its computer files with a “41”,
“42”, “341” or “342” in field captioned “SECURED_POOL_NBR” and (ii) deliver an Account Schedule to Discover Funding. 

(c) At all times Discover Bank shall identify the Accounts (and only the Accounts) in its computer files with a “41”,
“42”, “341” or “342” in the field captioned “SECURED_POOL_NBR”; provided, however, that Discover Bank may change the number used to identify any of the Accounts in its computer files, or the
caption of the field if Discover Bank records and files, at its own expense, any amendment to any financing statements with respect to the Receivables then existing and thereafter created as is necessary to preserve the perfection of the security
interest in such Receivables to Discover Funding after giving effect to such change, and shall deliver a file-stamped copy of such amendment or other evidence of such filing to the Trustee on or prior to the date of any such change. 

(d) The parties intend that the transfer of the Conveyed Assets by Discover Bank to Discover Funding be an absolute sale and not a secured
borrowing, including for accounting purposes. If the transaction under this Agreement were determined to be a loan rather than an absolute sale despite this intent of the parties, Discover Bank hereby grants to Discover Funding a first priority
security interest in all of Discover Bank’s right, title, and interest, whether now owned or hereafter acquired, in, to, and under the Conveyed Assets to secure Discover Bank’s obligations under this Agreement. This grant is a protective
measure and must not be construed as evidence of any intent contrary to the one expressed in this paragraph.

Servicing Agreement or may elect to designate additional accounts or participation interests under the Pooling and Servicing Agreement. In either case, Discover Funding may require that Discover Bank designate Additional Accounts under this
Agreement to enable Discover Funding to satisfy that obligation or election. Discover Funding shall give Discover Bank notice of this requirement to designate Additional Accounts under this Agreement prior to the related Addition Date. If Discover
Bank fails to designate Additional Accounts in compliance with that notice only because sufficient credit card accounts are not available to Discover Bank, that failure will not be a breach of this Agreement. 

(b) With respect to any Additional Accounts, Discover Bank shall cause the Master Servicer to prepare a reasonable estimate of the amount of
Finance Charge Receivables billed in such Additional Accounts for the Due Period in which such accounts are first designated as Additional Accounts. Such estimate shall be deemed to be the amount of Finance Charge Receivables billed in such
Additional Accounts in such Due Period absent manifest error. 
 (c) Discover Bank agrees to provide to Discover Funding such information,
certificates, financing statements, opinions and other materials as reasonably necessary to enable Discover Funding to satisfy its obligations under Section 2.10 of the Pooling and Servicing 

  
 9 

 
Agreement with respect to Additional Accounts or Participation Interests of Discover Bank. In the case of Additional Accounts, Discover Bank shall deliver to Discover Funding on the date
designated by Discover Funding (i) the Account Schedule required to be delivered pursuant to Section 2.1(b) with respect to such Additional Accounts, (ii) upon request by Discover Funding or the Trustee, a certificate setting
forth in reasonable detail the calculation of the estimate of the Finance Charge Receivables in such Additional Accounts and (iii) a duly executed written assignment covering the related Conveyed Assets, substantially in the form of Exhibit
A (the “Supplemental Conveyance”). 
 Section 2.3 Removal and Deletion of Accounts. 

(a) Discover Funding may remove Accounts from DCMT in accordance with Section 2.11 of the Pooling and Servicing Agreement. On each day on
which Accounts are removed from DCMT pursuant to Section 2.11 of the Pooling and Servicing Agreement, Discover Bank and Discover Funding may, but shall not be required to, by mutual agreement, remove Accounts from the operation of this
Agreement. Discover Bank agrees to provide to Discover Funding such information, certificates, financing statements opinions and other materials as are reasonably necessary to enable Discover Funding to satisfy its obligations under
Section 2.11 of the Pooling and Servicing Agreement with respect to the removal of Accounts. 
 (b) With respect to any removed
Accounts pursuant to Section 2.3(a), Discover Funding shall cause the Master Servicer to prepare a reasonable estimate of the amount of Finance Charge Receivables billed in such removed Accounts for the Due Period in which such accounts
are removed. Such estimate shall be deemed to be the amount of Finance Charge Receivables billed in such removed Accounts in such Due Period absent manifest error.

 Section 2.5 Transfer of Collateral
Certificate. 
 (a) Discover Bank, as the initial seller, transferred, assigned, set over, pledged and otherwise conveyed to the Note
Issuance Trust, without recourse (subject to the obligations in the Series 2007-CC Collateral Certificate Transfer Agreement), all right, title and interest of Discover Bank in and to the Series 2007-CC Collateral Certificate and the proceeds
thereof. Such conveyance of the Series 2007-CC Collateral Certificate and the proceeds thereof was and still is intended to constitute a sale, and not a secured borrowing, for accounting purposes. Nevertheless, Discover Bank, as the initial seller,
also granted to the Note Issuance Trust a security interest in and to all of Discover Bank’s right, title and interest, whether then owned or thereafter acquired, in, to and under the Series 2007-CC Collateral Certificate, all accounts, general
intangibles, chattel paper, instruments, documents, money, deposit accounts, certificates of deposit, goods, letters of credit, letter of credit rights, advices of credit and investment property consisting of; arising from, or relating to the Series
2007-CC Collateral Certificate, and the proceeds thereof (collectively, the “Indenture Collateral”), to secure the obligations of Discover Bank as the initial transferor. 

(b) The parties intend and agree that, since the transfer by Discover Bank specified in Section 2.5(a) above, all right, title,
and interest in, to, and under the Series 2007-CC Collateral Certificate, all other items of the Trust Estate, and all proceeds thereof have been owned solely by the Note Issuance Trust, subject only to the security interest of the Indenture Trustee
under the Indenture. If Discover Funding were determined to have any right, title, or interest in, to, or under the Series 2007-CC Collateral Certificate, any other item of the Trust Estate, or any proceeds thereof despite this intent of the
parties, Discover Funding hereby transfers and assigns to the Note Issuance Trust, without recourse, all of Discover Funding’s right, title, and interest in, to, and under the Series 2007-CC Collateral Certificate, all other items of the Trust
Estate, and all proceeds thereof and further grants to the Note Issuance Trust a security interest in all of Discover Funding’s right, title, and interest, whether now owned or hereafter acquired, in, to, and under the Series 2007-CC Collateral
Certificate, all other items of the Trust Estate, and all proceeds thereof to secure the obligations of Discover Funding. The parties intend that these transfers by Discover Funding constitute a sale, and not a secured borrowing, for accounting
purposes. These transfers by Discover Funding are a protective measure and must not be construed as evidence of any intent contrary to the one expressed in the first sentence of this paragraph. Discover Bank hereby transfers and assigns all of its
rights and obligations under the Series 2007-CC Collateral Certificate Transfer Agreement to Discover Funding.

provided that Discover Bank may elect, in its sole discretion, to contribute Receivables (or any portion thereof) to Discover Funding from time to
time; provided further that, if Discover Funding elects, in its sole discretion, an amount equal to the portion of the Purchase Price for such Receivables not paid to Discover Bank shall be deemed to be a borrowing by Discover Funding from
Discover Bank under the Long Term Intercompany Note so long as the Adequate Capital Test is satisfied on such day. 
 (c) Any portion of the
Purchase Price that is not (i) deemed a borrowing under the Long Term Intercompany Note or (ii) deemed a capital contribution, in each case pursuant to clause (b) above, shall be payable by Discover Funding to Discover Bank in

Account Combination, the parties hereto will increase or decrease the related Purchase Price (a “Purchase Price Adjustment”). The amount of that Purchase Price Adjustment is equal to the amount by which that Receivable has been
reduced or increased. 
 (b) If a Purchase Price Adjustment causes the Purchase Price to be a negative number, Discover Bank must pay to
Discover Funding in immediately available funds on the related Purchase Price Payment Date an amount equal to the amount by which the Purchase Price Adjustment exceeds the unadjusted Purchase Price. 

(c) For the avoidance of doubt, all amounts owing to or from Discover Bank and Discover Funding hereunder may be netted.

 (a) Security Interests.
Except for the conveyances hereunder, Discover Bank will not sell, pledge, assign or transfer to any other Person, or grant, create, incur, assume or suffer to exist any Lien on any Receivable or any Interchange transferred to Discover Funding by
Discover Bank, whether existing as of the Cut-Off Date or thereafter created, or any interest therein, and Discover Bank shall defend the right, title, and interest of Discover Funding in, to and under such Receivables and such Interchange, whether
now existing or hereafter created, against all claims of third parties claiming through or under Discover Bank. Discover Bank shall, if so requested by Discover Funding, provide information to third parties (which information may be provided by
Discover Bank directly or through Discover Funding) concerning the Accounts, the Receivables and the Interchange sufficient to comply with the UCC as in effect in the Applicable State. 

(b) Credit Agreements. Discover Bank shall cause the Servicer, as its agent, to service and administer the Accounts, the Receivables
under which have been transferred to Discover Funding by such Discover Bank and the receivables in Charged-Off Accounts, which are serviced by such Servicer, in a particular state or similar jurisdiction in accordance with policies identical to
those used in servicing and administering other of Discover Bank’s credit card accounts in such jurisdiction. The terms and provisions of a Credit Agreement may be changed in any respect (including, without limitation, the calculation of the
amount, or the timing, of charge-offs) only if such change is made applicable to Discover Bank’s entire portfolio of accounts of that general type, obligors of which are resident in a particular affected state or similar jurisdiction, and not
only to such Accounts. 
 (c) Account Allocations. In the event that Discover Bank is unable for any reason to transfer Receivables
to Discover Funding in accordance with the provisions of this Agreement (including, without limitation, by reason of any governmental agency having regulatory authority over Discover Bank or any court of competent jurisdiction ordering that Discover
Bank not convey any additional Principal Receivables to Discover Funding) then, in any such event, Discover Bank agrees to allocate and pay to Discover Funding, after the date of such inability, all Collections with respect to Receivables that would
have been Principal Receivables but for the inability to transfer such Receivables (up to an aggregate amount equal to the amount of Principal Receivables in DCMT on such date with respect to Principal Receivables transferred to Discover Funding by
Discover Bank); and Discover Bank agrees to have such amounts applied as Collections under the Pooling and Servicing Agreement. If Discover Bank is unable pursuant to any Requirement of Law to allocate payments on the Accounts as described above,
Discover Bank agrees that it shall, in any such event, allocate after such date payments on each Account with respect to the principal balance of such Account first to the oldest principal balance of such Account and to have such payments applied as
Collections in accordance with the Pooling and Servicing Agreement. The parties hereto agree that Finance Charge Receivables, whenever created, accrued in respect of Principal Receivables that have been conveyed to Discover Funding by Discover Bank
shall continue to be owned by Discover Funding notwithstanding any cessation of the transfer of additional Principal Receivables to the Trust, and Collections with respect thereto shall continue to be allocated and paid. 

  
 17 

 (d) Receivables and Interchange Not to be Evidenced by Promissory Notes. Discover Bank
will not take any action to cause any Receivable or any Interchange to be evidenced by any instrument (as defined in the UCC as in effect in the Applicable State with respect to Discover Bank) except in connection with its enforcement or collection
of an Account. 
 (e) Notice to Trustee. Promptly upon receipt of notice by any officer of Discover Bank that any liens (other than
those contemplated by this Agreement or any Supplemental Conveyance) have been placed on the Receivables, Discover Bank shall notify Discover Funding in writing of such liens. 

(f) Discover Bank will not change its name or its type or jurisdiction of organization without first delivering to Discover Funding an opinion
of counsel stating that all actions and filings that are necessary or appropriate to maintain the perfection and the priority of Discover Funding’s ownership interest in the Receivables have been taken or made. 

(g) On March 31 in each calendar year, beginning March 31, 2017, Discover Bank will deliver to Discover Funding and the DCMT Trustee
an opinion of counsel (i) stating that no further filing of any financing statement, amendment of financing statement, or continuation statement is then necessary to perfect Discover Funding’s ownership interest in the Receivables, and
(ii) stating that no further filing of any financing statement, amendment of financing statement, or continuation statement will be necessary prior to March 31 of the next calendar year to maintain the perfection of Discover Funding’s
ownership interest in the Receivables or, if that is not the case, identifying each filing that will be necessary prior to March 31 of that calendar year.

 EXHIBIT A 

SUPPLEMENTAL CONVEYANCE 
 This
Supplemental Conveyance No. [    ] (this “Supplemental Conveyance”) is made as of [ ], between Discover Bank, a Delaware banking corporation (“Discover Bank”), and Discover Funding LLC, a
Delaware limited liability company (“Discover Funding”). 
 BACKGROUND 

Discover Bank and Discover Funding are designating additional credit card accounts under the Receivables Sale and Contribution Agreement,
dated as of December 22, 2015, between Discover Bank and Discover Funding (the “Receivables Sale and Contribution Agreement”). 

AGREEMENT 
 In consideration of
the mutual promises in this Supplemental Conveyance and for other valuable consideration, the receipt and adequacy of which are acknowledged, the parties agree to the following: 

1. Defined Terms and Rules of Construction. Each capitalized term is defined in this Section 1, or if not defined here, in the
Receivables Sale and Contribution Agreement. Rules of construction in the Receivables Sale and Contribution Agreement apply in this Supplemental Conveyance. The following definitions apply in this Supplemental Conveyance: 

“Addition Date” means, for the Additional Accounts,
[            ]. 
 “Additional Account” means each Discover
card account that is designated as an Account under this Supplemental Conveyance and that is identified on Schedule 1 to this Supplemental Conveyance. 

“Additional Account Cut-Off Date” means, for the Additional Accounts, the [close] of business on
[            ]. 
 “Additional Conveyed Assets” has the meaning
set forth in Section 3(a). 
 “Discover Bank” has the meaning set forth in the first paragraph of this
Supplemental Conveyance. 
 “Discover Funding” has the meaning set forth in the first paragraph of this Supplemental
Conveyance. 
 “Receivables Sale and Contribution Agreement” has the meaning set forth in the Background. 

“Supplemental Conveyance” has the meaning set forth in the first paragraph of this document. 

  
 A-1 

 2. Designation of Additional Accounts. The Additional Accounts identified on Schedule 1 to
this Supplemental Conveyance are designated as Accounts under this Supplemental Conveyance and the Receivables Sale and Contribution Agreement from and after the Addition Date. Schedule 1 is fully incorporated into this Supplemental Conveyance and
the Receivables Sale and Contribution Agreement and supplements the Account Schedule under the Receivables Sale and Contribution Agreement from and after the Addition Date. 

3. Sale of Additional Conveyed Assets. In consideration of Discover Funding’s payment of each related Purchase Price under the
Receivables Sale and Contribution Agreement, Discover Bank hereby sells and assigns to Discover Funding, without recourse, all of Discover Bank’s right, title and interest in, to, and under (i) the Receivables existing on the Additional
Account Cut-Off Date and arising after the Additional Account Cut-Off Date in each Additional Account (including any related Surviving Account), (ii) all Interchange allocable to those Receivables, (iii) all Collections on those
Receivables, including Recovered Amounts and (iv) all proceeds of any of this property (collectively, the “Additional Conveyed Assets”). Discover Funding hereby accepts the Additional Conveyed Assets sold under this
Supplemental Conveyance. 
 Discover Bank must take all actions relating to this sale of the Additional Conveyed Assets that are required
under the Receivables Sale and Contribution Agreement. 
 The parties intend that the transfer of the Additional Conveyed Assets by Discover
Bank to Discover Funding be an absolute sale and not a secured borrowing, including for accounting purposes. If the transaction under this Supplemental Conveyance were determined to be a loan rather than an absolute sale despite this intent of the
parties, Discover Bank hereby grants to Discover Funding a first priority security interest in all of Discover Bank’s right, title, and interest, whether now owned or hereafter acquired, in, to, and under the Additional Conveyed Assets to
secure Discover Bank’s obligations under this Supplemental Conveyance and the Receivables Sale and Contribution Agreement. This grant is a protective measure and must not be construed as evidence of any intent contrary to the one expressed in
this paragraph. 
 4. Representations and Warranties of Discover Bank. Discover Bank acknowledges its representations and warranties
relating to the Additional Accounts that are made on the Addition Date under Sections 4.1 and 4.2 of the Receivables Sale and Contribution Agreement. 

5. Ratification. This Supplemental Conveyance supplements the Receivables Sale and Contribution Agreement from and after the Addition
Date, and the parties ratify the Receivables Sale and Contribution Agreement as supplemented by this Supplemental Conveyance. 
 6.
Miscellaneous. This Supplemental Conveyance may be executed in any number of counterparts, each of which will be considered an original, but all of which together will constitute one agreement. Each party must take all actions that are
reasonably requested by the other party to effect more fully the purposes of this Supplemental Conveyance. 

  
 A-2 

 7. GOVERNING LAW. Except as otherwise specifically provided herein, this Supplemental
Conveyance shall be construed in accordance with the internal laws of the State of New York without reference to its conflict of law provisions, and the obligations, rights and remedies of the parties hereunder shall be determined in accordance with
such laws. Each of Discover Bank and Discover Funding hereby irrevocably consents and agrees that any legal or equitable action or proceeding brought by it arising under or in connection with this Supplemental Conveyance shall be brought exclusively
in any federal or state court in the State of Delaware, and hereby irrevocably waives, and agrees not to assert in any action or proceeding brought against Discover Bank or Discover Funding, any claim that it is not personally subject to the
jurisdiction of any such court.

prior to the Effective Date, Discover Bank’s execution of such action under the 2010 Pooling and Servicing Agreement shall constitute satisfaction of such requirement; and

shall be required to be made if, at any time during such period, such Trust Portfolio Repurchase Event shall not adversely affect in any material respect the interests of the Investor Certificateholders as a whole. In such case, (i) Discover
Funding as the Holder of the Transferor Certificate shall deposit into each Series Distribution Account for each Series then outstanding on or before the Distribution Date with respect to such Series an amount equal to the purchase price for such
Series, as set forth in the next sentence, and (ii) the Trustee shall, except in the case of a Trust Portfolio Repurchase Event caused by an Assignment of Additional Accounts, pay the amount on deposit in each Series Principal Funding Account
with respect to Series Principal Collections to the Series Distribution Account with respect to each such Series on such Distribution Date, and the total amount deposited into the Series Distribution Account pursuant to clauses (i) and
(ii) shall be distributed to the Investor Certificateholders pursuant to Section 12.02. 
 The purchase price with
respect to each Series will be equal to (i) the Series Investor Interest on the Distribution Date with respect to such Series immediately preceding the date such deposit is made (after giving effect to any distributions made on such
Distribution Date) plus (ii) all accrued but unpaid Certificate Interest on the outstanding amount of Investor Certificates of such Series to be so purchased through the date set for such purchase; provided, however, that
if an assignment of Additional Accounts results in a Trust Portfolio Repurchase Event, only the Receivables of such Additional Accounts shall be repurchased at a price with respect to each Series equal to the product of (i) the Series
Percentage with respect to Principal Receivables for the next following Distribution Date with respect to such Series and (ii) the amount of Receivables attributable to the Additional Accounts, and such purchase price shall be applied as
Collections in respect of such Receivables in accordance with each applicable Series Supplement and deposited in the Group Collections Account relating to each Series. Payment of the purchase price and the amounts on deposit in the Collections
Account with respect to the preceding Due Period shall be considered a prepayment in full of such Receivables. On each Distribution Date on which such amount is scheduled to be deposited, the Receivables to be so purchased and all the monies due or
to become due with respect thereto and all proceeds of such Receivables (including, if applicable, all amounts on deposit in the Series Interest Funding Account for each Series) shall be released to Discover Funding as the Holder of the Transferor
Certificate, and the Trustee shall execute and deliver such instruments of transfer or assignment including, without limitation, any document necessary to release the Trust’s security interest in such Receivables and to release any filing
evidencing or perfecting such security interest, in each case without recourse, representation or warranty (except for the warranty that since the date of transfer by the Transferor under this Agreement the Trustee has not sold, transferred or
encumbered any such Receivables or interest therein), as shall be reasonably requested by Discover Funding as the Holder of the Transferor Certificate to vest in Discover Funding as the Holder of the Transferor Certificate, or its designee or
assignee, all right, title and interest of the Trust in and to such Receivables, all monies due or to become due with respect thereto and all proceeds of such Receivables.

 SECTION 2.06 Series Repurchase Obligations of the Transferor. 

(a) Series Repurchase Event. If, as of the Series Closing Date with respect to any Series, the Series Supplement for such Series
does not constitute a legal, valid and binding obligation of the Transferor enforceable against the Transferor in accordance with its terms, except as such enforceability may be limited by insolvency, bankruptcy, reorganization or other laws
relating to the enforcement of creditors’ rights or by general equity principles, then a Series Repurchase Event shall have occurred. The Trustee shall have no duty to conduct any affirmative investigation for purposes of this Section
2.06(a). 
 (b) Repurchase of Series. If at any time a Series Repurchase Event shall have occurred and be
continuing, either the Trustee or the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Series Invested Amount with respect to such Series, by notice then given in writing to the
Transferor and the Master Servicer (and to the Trustee if given by the Investor Certificateholders of such Series), may direct Discover Funding as the Holder of the Transferor Certificate to purchase the Investor Certificates of such Series within
60 days of such notice, or within such longer period as may be specified in such notice, and Discover Funding as the Holder of the Transferor Certificate shall be obligated to purchase such Investor Certificates on a Distribution Date with respect
to such Series occurring within such period, subject to the provisions of Section 2.08, on the terms and conditions set forth below; provided, however, that no such purchase shall be required to be made if, at any time during such
period, such Series Repurchase Event shall not adversely affect in any material respect the interests of the Investor Certificateholders of such Series as a whole. In such case, on such Distribution Date, (i) Discover Funding as the Holder of
the Transferor Certificate shall deposit into the Series Distribution Account an amount equal to the sum of (x) the Series Investor Interest on the Distribution Date with respect to such Series immediately preceding the date such deposit is
made (after giving effect to any distributions made on such Distribution Date) and (y) all accrued but unpaid Certificate Interest on the outstanding amount of Investor Certificates to be so purchased through the date set for such purchase, and
(ii) the Trustee shall pay the amount on deposit in the Series Principal Funding Account with respect to such Series to the Series Distribution Account with respect to such Series, and the total amount deposited into the Series Distribution
Account pursuant to clauses (i) and (ii) shall be distributed to the Investor Certificateholders of such Series pursuant to Section 12.02. 

SECTION 2.07 Repurchase Obligations of the Transferor Relating to Receivables. 

(a) Receivable Repurchase Events. In the event that each Receivable that is transferred to the Trust is not, as of the time of
such transfer, an Eligible Receivable and such event has a material adverse effect on the Certificateholders’ interest in the Receivables as a whole and is not cured within 60 days of the earlier of (i) actual knowledge of such event by
the Transferor or (ii) receipt by the Transferor of written notice of any such event given by the Trustee, then a Receivable Repurchase Event shall have occurred. Upon receipt of actual knowledge of any such event, the Transferor shall deliver
a written notice to such effect to the Rating Agencies and the Trustee. The determination of materiality pursuant to this Section 2.07(a) shall be made by an officer of the Master Servicer in his sole reasonable judgment. Notwithstanding
the foregoing, if (a) the amount of Principal Receivables in the Trust at the end  

  
 26 

 
of the Due Period in which the Transferor obtained (i) actual knowledge of the transfer of a Receivable that is not an Eligible Receivable, or (ii) written notice of such a transfer
from the Trustee, would be less than the Minimum Principal Receivables Balance if such Receivables were excluded from the amount of Principal Receivables used in such determination, and (b) Discover Bank’s short term debt rating from
Standard & Poor’s is less than A-1, then a Receivables Repurchase Event shall automatically occur with respect to each such Receivable that was not an Eligible Receivable upon transfer and the Receivables in each Account to which such
event relates shall be removed from the Trust in accordance with Section 2.07(b). The Trustee shall have no duty to conduct any affirmative investigation as to the eligibility of any Receivable for purposes of this
Section 2.07(a) but shall provide written notice to the Transferor referred to in this Section 2.07(a) when directed by any Certificateholder. 

(b) Purchase of Ineligible Receivables. If at any time a Receivable Repurchase Event shall have occurred and be continuing,
Discover Funding as the Holder of the Transferor Certificate shall purchase all the Receivables in each Account in which there is any Receivable as to which such event relates (an “Ineligible Receivable”), subject to the provisions
of Section 2.08, on the terms and conditions set forth below. Discover Funding as the Holder of the Transferor Certificate shall purchase all the Receivables in each Account with an Ineligible Receivable on the Trust Distribution Date
related to the then current Due Period by directing the Master Servicer to deduct the amount of such Receivables which are Principal Receivables from the aggregate amount of Principal Receivables in the Trust. On and after the date of such
repurchase, Receivables so purchased shall not be included in the calculation of any Series Percentage, the Transferor Percentage or the Transferor Interest. In the event that such an exclusion of Receivables from the calculation of the Transferor
Interest would cause the Transferor Interest to be a negative number on the date of purchase of such Receivables, Discover Funding as the Holder of the Transferor Certificate shall make a deposit in the Collections Account in immediately available
funds in an amount equal to the amount by which the Transferor Interest would be reduced below zero. Such deposit shall be considered a payment in full of such Receivables and shall be applied as Collections in respect of such Receivables in
accordance with Section 4.03. Upon each such purchase of Receivables by Discover Funding as the Holder of the Transferor Certificate, the Trust shall automatically and without further action be deemed to sell, transfer, assign and
otherwise convey to Discover Funding as the Holder of the Transferor Certificate without recourse, representation or warranty (except for the warranty that since the date of transfer by the Transferor under this Agreement the Trustee has not sold,
transferred or encumbered any such Receivable or interest therein), all the right, title and interest of the Trust in and to such Receivables, all monies due or to become due with respect thereto, all proceeds thereof and all Receivables thereafter
created in such Account. The Trustee shall execute such documents and instruments of transfer or assignment including, without limitation, any document necessary to release the Trust’s security interest in such Receivables and to release any
filings evidencing or perfecting such security interest and take such other actions as shall reasonably be requested by Discover Funding as the Holder of the Transferor Certificate to effect the conveyance of such Receivables pursuant to this
section. The obligation of Discover Funding as the Holder of the Transferor Certificate to purchase any Ineligible Receivables, and to make the deposits, if any, required to be made to the Collections Account as provided in this
Section 2.07(b), shall constitute the sole remedy respecting the event giving rise to such obligation available to the Certificateholders (or the Trustee on behalf of the Certificateholders). 

  
 27 

 SECTION 2.08 [Reserved]. 

SECTION 2.09 Covenants of the Transferor. The Transferor hereby covenants that: 

(a) Security Interests. Except for the conveyances hereunder, the Transferor will not sell, pledge, assign or transfer to any
other Person, or grant, create, incur, assume or suffer to exist any Lien on any Receivable or any Interchange transferred to the Trust by the Transferor, whether existing as of the Effective Date or thereafter created, or any interest therein, and
the Transferor shall defend the right, title, and interest of the Trust in, to and under such Receivables and such Interchange, whether now existing or hereafter created, against all claims of third parties claiming through or under the Transferor.
The Transferor shall, if so requested by the Trustee, as agent for the Transferor, provide information to third parties (which information may be provided by the Transferor directly or through the Trustee) concerning the Accounts, the Receivables
and the Interchange sufficient to comply with the UCC as in effect in the Applicable State. 
 (b) Enforcement of
Receivables Sale and Contribution Agreement. The Transferor agrees to take all actions necessary and appropriate to enforce its rights and claims under the Receivables Sale and Contribution Agreement. 

(c) Account Allocations. In the event that the Transferor is unable for any reason to transfer Receivables to the Trust in
accordance with the provisions of this Agreement (including, without limitation, by reason of any governmental agency having regulatory authority over the Transferor or any court of competent jurisdiction ordering that the Transferor not convey any
additional Principal Receivables to the Trust) then, in any such event, the Transferor agrees to allocate and pay to the Trust, after the date of such inability, all Collections with respect to Receivables that would have been Principal Receivables
but for the inability to transfer such Receivables (up to an aggregate amount equal to the amount of Principal Receivables in the Trust on such date with respect to Principal Receivables transferred to the Trust by the Transferor); and the
Transferor agrees to have such amounts applied as Collections in accordance with Section 4.03. If the Transferor is unable pursuant to any Requirement of Law to allocate payments on the Accounts as described above, the Transferor agrees
that it shall, in any such event, allocate after such date payments on each Account with respect to the principal balance of such Account first to the oldest principal balance of such Account and to have such payments applied as Collections in
accordance with Section 4.03. The parties hereto agree that Finance Charge Receivables, whenever created, accrued in respect of Principal Receivables that have been conveyed to the Trust by the Transferor shall continue to be a part of
the Trust notwithstanding any cessation of the transfer of additional Principal Receivables to the Trust, and Collections with respect thereto shall continue to be allocated and paid in accordance with Section 4.03. 

(d) Receivables and Interchange Not to be Evidenced by Promissory Notes. The Transferor will not take any action to cause any
Receivable or any Interchange to be evidenced by any instrument (as defined in the UCC as in effect in the Applicable State with respect to the Transferor) except in connection with its enforcement or collection of an Account. 

  
 28 

 (e) Notice to Trustee. Promptly upon receipt of notice by any officer of the
Transferor that any liens (other than those contemplated by this Agreement or any Assignment) have been placed on the Receivables, the Transferor shall notify the Trustee in writing of such liens. 

(f) Separate Company Existence. The Transferor shall comply with Section 9(j)(iv) and Section 10 of the Transferor LLC
Agreement and shall cause its Independent Director (as defined in the Transferor LLC Agreement) to be from, or to be provided by, a nationally recognized corporate services provider.  

SECTION 2.10 Addition of Accounts. 

(a) Required Additions.  

(i) In the event that the amount of Principal Receivables in the Trust at the end of any Due Period is less than the Minimum
Principal Receivables Balance, Discover Funding as the Holder of the Transferor Certificate shall designate, effective no later than the commencement of the following Due Period, Additional Accounts to be included as Accounts, which may be credit
accounts originated by Discover Bank or affiliates of Discover Bank, whether or not such accounts are Discover Card accounts, and shall transfer to the Trust (A) all receivables existing in such Additional Accounts on the date of designation,
to be included as Receivables and (B) all receivables created in such Additional Accounts on and after the effective date of designation, and the corresponding portion of Interchange arising on and after the effective date of such designation,
in each case subject to the conditions set forth in Section 2.10(b) or (c), as applicable, in a sufficient amount such that, after giving effect to such additions, the amount of Principal Receivables in the Trust is at least equal
to the Minimum Principal Receivables Balance. 
 (ii) In lieu of, or in addition to, designating Additional Accounts pursuant
to paragraph (i) above, Discover Funding as the Holder of the Transferor Certificate may, subject to the applicable conditions set forth in Section 2.10(d), convey to the Trust participations representing undivided interests in a
pool of assets primarily consisting of receivables in revolving credit card accounts and collections thereon (“Participation Interests”). The addition of Participation Interests to the Trust pursuant to this Section 2.10
shall be effected by an amendment to this Agreement, dated the applicable Addition Date, pursuant to Section 13.01(a). 

(b) Conditions to the Designation of Discover Card Accounts Originated by Discover Bank as Additional Accounts. Discover Funding
as the Holder of the Transferor Certificate shall be permitted to designate Discover Card accounts originated by Discover Bank as “Additional Accounts” if the following conditions are satisfied on or prior to the Addition Date (except with
respect to Section 2.10(b)(i), which shall be satisfied on or prior to the fifth Business Day following the Addition Date): 

(i) the Transferor shall have delivered to the Trustee a written assignment (including an acceptance by the Trustee on behalf
of the Trust for the benefit 

  
 29 

 
of the Certificateholders) in substantially the form of Exhibit A and a computer file, hard copy or microfiche list containing a true and complete list of all such Additional Accounts
identified by account number, which computer file, hard copy or microfiche list shall be deemed to be an amendment to Schedule 1 hereto as of the date of such Assignment; 

(ii) the Servicer with respect to such Additional Accounts shall have delivered a certificate of a Servicing Officer confirming
that the Additional Accounts were not selected on the basis of any selection criteria believed by such Servicer to be materially adverse to the interests of the Holders of any Class of any Series then outstanding or any Credit Enhancement Provider;

 (iii) Discover Funding as the Holder of the Transferor Certificate shall have delivered to the Trustee an Opinion or
Opinions of Counsel concerning the perfection of the Trust’s security interest in the Receivables in such Additional Accounts, and concerning insolvency and related matters with respect to such Receivables, that will not cause the rating of any
Class of any Series then outstanding to be withdrawn or lowered below the Required Rating by any Rating Agency; and 
 (iv)
Discover Funding as the Holder of the Transferor Certificate shall have delivered notice of such proposed assignment of Additional Accounts to the Rating Agencies, and Standard & Poor’s (and, in the event that the proposed assignment
of Additional Accounts is not required pursuant to Section 2.10(a), Moody’s) shall have advised Discover Funding as the Holder of the Transferor Certificate that such assignment of Additional Accounts would not cause the rating of
any Class of any Series then outstanding to be lowered below the Required Rating or withdrawn. 
 (c) Conditions to Designation of
Additional Accounts, other than Discover Card Accounts Originated by Discover Bank. In addition to designations of Additional Accounts as described in Section 2.10(b), subject to the conditions set forth below, Discover
Funding as the Holder of the Transferor Certificate shall be permitted to designate as Additional Accounts (x) credit accounts originated by Discover Bank which are not Discover Card accounts and/or (y) credit accounts originated by an
affiliate of Discover Bank (an “Additional Originator”), which may or may not be Discover Card accounts. Discover Funding as the Holder of the Transferor Certificate shall be permitted to designate such accounts as Additional
Accounts if the following conditions are satisfied on or prior to the Addition Date (except with respect to Section 2.10(c)(i), which shall be satisfied on or prior to the fifth Business Day following the Addition Date): 

(i) the Transferor shall have delivered to the Trustee a written assignment (including an acceptance by the Trustee on behalf
of the Trust for the benefit of the Certificateholders) in substantially the form of Exhibit A and a computer file, hard copy or microfiche list containing a true and complete list of all such Additional Accounts, identified by originator and
account number, which computer file, hard copy or microfiche list shall be deemed to be an amendment to Schedule 1 hereto as of the date of such Assignment; 

  
 30 

 (ii) the Servicer with respect to such Additional Accounts shall have delivered a
certificate of a Servicing Officer confirming that such Additional Accounts were not selected on the basis of any selection criteria believed by such Servicer to be materially adverse to the interests of the Holders of any Class of any Series then
outstanding or any Credit Enhancement Provider; 
 (iii) Discover Funding as the Holder of the Transferor Certificate shall
have delivered to the Trustee an Opinion or Opinions of Counsel concerning the perfection of the Trust’s security interest in the Receivables in such Additional Accounts, and concerning insolvency and related matters with respect to such
Receivables, that will not cause the rating of any Class of any Series then outstanding to be withdrawn or lowered below the Required Rating by any Rating Agency; and 

(iv) Discover Funding as the Holder of the Transferor Certificate shall have delivered notice of such proposed assignment of
Additional Accounts to the Rating Agencies and the Rating Agencies shall have advised Discover Funding as the Holder of the Transferor Certificate that such assignment of Additional Accounts would not cause the rating of any Class of any Series then
outstanding to be lowered below the Required Rating or withdrawn. 
 (d) Conditions to Designation of Participation Interests.
In addition to designations of Additional Accounts as described in Sections 2.10(b) and 2.10(c), subject to the conditions set forth below, Discover Funding as the Holder of the Transferor Certificate shall be permitted to convey
to the Trust Participation Interests. Discover Funding as the Holder of the Transferor Certificate shall be permitted to convey such Participation Interests to the Trust if, on or prior to the Addition Date, the following conditions are
satisfied: 
 (i) Discover Funding as the Holder of the Transferor Certificate shall have delivered a certificate
stating that Discover Funding as the Holder of the Transferor Certificate reasonably believes that the addition of the Participation Interests will not be materially adverse to the interests of the Holders of any Class of any Series then outstanding
or any Credit Enhancement Provider; 
 (ii) Discover Funding as the Holder of the Transferor Certificate shall have delivered
to the Trustee an Opinion or Opinions of Counsel concerning the perfection of the Trust’s security interest in the Participation Interests and concerning insolvency and related matters with respect to such Participation Interests, that will not

(iii) Discover Funding as the Holder of the Transferor Certificate shall have delivered notice of such proposed conveyance of
Participation Interests to the Rating Agencies and the Rating Agencies shall have advised Discover Funding as the Holder of the Transferor Certificate that such conveyance of Participation Interests would not cause the rating of any Class of any

 (e) Calculation of Finance Charge Receivables.
The Master Servicer shall cause the appropriate Servicer with respect to any Additional Accounts to prepare a reasonable estimate of the amount of Finance Charge Receivables billed in such Additional Accounts in the Due Period in which such
Receivables are first included in the Trust, which estimate shall be deemed to be the amount of Finance Charge Receivables billed in such Additional Accounts in such Due Period, absent manifest error. Such Servicer shall provide to the Trustee, upon
request, a certificate of a Servicing Officer setting forth in reasonable detail its calculation of such estimate. 

  
 31 

 SECTION 2.11 Removal of Accounts. 

(a) Optional Removals. From time to time, Discover Funding as the Holder of the Transferor Certificate may, but shall not be obligated
to, (i) designate Accounts for deletion and removal from the Trust (“Removed Accounts”) and (ii) cause the Trust to transfer to the Holder of the Transferor Certificate (A) all receivables existing in such Removed
Accounts on the date of designation and (B) all receivables created in such Removed Accounts on and after the effective date of designation, and the corresponding portion of Interchange arising on and after the effective date of such
designation (the “Removed Interchange”). Such deletion and removal shall be effective as of the day specified in the notice referred to in the following sentence, which (i) may be any day with respect to removals of Accounts
(but shall be effective as of the last day of any Due Period with respect to the Removed Interchange) covered by Section 2.11(b)(vi)(A), and (ii) shall be the last day of any Due Period with respect to removals of Accounts (and the
Removed Interchange) covered by Section 2.11(b)(vi)(B) or (C) (any such effective date, the “Removal Date”), subject to the notice requirement and other conditions set forth below. On or before the fifth
Business Day prior to the Removal Date (the “Removal Notice Date”), Discover Funding as the Holder of the Transferor Certificate shall give the Trustee, the Master Servicer and any Credit Enhancement Provider written notice that the
receivables from such Removed Accounts and the Removed Interchange are to be reassigned by the Trustee to Discover Funding as the Holder of the Transferor Certificate effective as of the Removal Date. 

(b) Conditions to the Designation of Removed Accounts. Discover Funding as the Holder of the Transferor Certificate shall be
permitted to designate and require reassignment to the Holder of the Transferor Certificate of the Receivables from Removed Accounts and the Removed Interchange only upon satisfaction of the following conditions: 

(i) As of the Removal Date, the aggregate amount of Principal Receivables in the Trust, less the aggregate amount of Principal
Receivables in such Removed Accounts, shall not be less than the Minimum Principal Receivables Balance; 
 (ii) The removal
of the Removed Accounts on any Removal Date shall not, in the reasonable belief of the Transferor cause either (A) an Amortization Event to occur or (B) the Deficit Accumulation Amount or Deficit Liquidation Amount, as applicable, with
respect to any Series then outstanding on any Distribution Date to be greater than zero; 

  
 32 

 (iii) On or prior to the fifth Business Day following the Removal Date, the
Transferor shall have delivered to the Trustee (A) for execution a written assignment substantially in the form of Exhibit C hereto, which shall include a warranty of the Trustee that since the date of transfer by the Transferor under
this Agreement the Trustee has not sold, transferred or encumbered any such Receivable, the Removed Interchange or interest in either and (B) a computer file, microfiche list or hard copy containing a true and complete list of all such Removed
Accounts identified by originator and account number and containing the amount of Receivables in such Removed Accounts as of the Removal Date, which computer file or microfiche list shall as of the Removal Date modify and amend Schedule 1 hereto by
deleting therefrom information with respect to any Removed Account and be made a part of this Agreement; 
 (iv) Discover
Funding as the Holder of the Transferor Certificate shall represent and warrant that no selection procedures believed by the Transferor to be materially adverse to the interests of the Holders of any Class of any Series then outstanding, or any
Credit Enhancement Provider, were utilized in selecting the Removed Accounts; 
 (v) Discover Funding as the Holder of the
Transferor Certificate shall have delivered notice of such proposed reassignment to the Rating Agencies and the Rating Agencies shall have advised the Transferor that such reassignment would not cause the rating of any Class of any Series then
outstanding to be withdrawn or lowered below the Required Rating; 
 (vi) The Removed Accounts shall meet one of the
following criteria: 
 (A) Each of such Accounts is a Charged-Off Account; provided that the Transferor shall
transfer to the Trust all proceeds received with respect to any Removed Account that is a Charged-Off Account, such amounts to constitute Recovered Amounts under the terms of this Agreement; 

(B) Such Accounts were randomly selected from the Accounts; provided that such random selection process need not
include selection of Charged-Off Accounts; or 
 (C) Such Accounts were originated or maintained in connection with an
affinity or private-label arrangement, and such affinity or private-label arrangement has been cancelled by a third party or has expired; provided, however, that Accounts originated or maintained pursuant to an affinity or
private-label arrangement shall only be removed pursuant to this Section 2.11(b)(vi)(C) if, prior to the cancellation or expiration of such arrangement, the Master Servicer designated such arrangement in writing to the Trustee as an
arrangement with respect to which these provisions apply; and 
 (vii) Discover Funding as the Holder of the Transferor
Certificate shall have delivered to the Trustee an Officer’s Certificate confirming the items set forth in (i), (ii), (iv), (v) and (vi) above. The Trustee may conclusively rely on such Officer’s Certificate, shall have no duty
to make inquiries with regard to the matters set forth therein and shall incur no liability in so relying. 

  
 33 

 Upon satisfaction of the above conditions, the Trustee shall execute and deliver the reassignment
to Discover Funding as the Holder of the Transferor Certificate, and the Receivables from the Removed Accounts and the Removed Interchange shall no longer constitute a part of the Trust. 

(c) Calculation of Finance Charge Receivables. The Master Servicer shall cause the appropriate Servicer with respect to any
Removed Accounts to prepare a reasonable estimate of the amount of Finance Charge Receivables billed in such Removed Accounts in the Due Period in which such Receivables are removed from the Trust, which estimate shall be deemed to be the amount of
Finance Charge Receivables billed in such Removed Accounts in such Due Period, absent manifest error. Such Servicer shall provide the Trustee, upon request, a certificate of a Servicing Officer setting forth in reasonable detail its calculation of
such estimate. 
 ARTICLE III. 

ADMINISTRATION AND SERVICING OF RECEIVABLES 

SECTION 3.01 Acceptance of Appointment and Other Matters Relating to the Master Servicer. 

(a) In connection with and in consideration for the conveyance of the Receivables to the Trust by the Transferor, and the issuance of the
Transferor Certificate to the Transferor, Discover Funding as the Holder of the Transferor Certificate and the Trustee agree to cause Discover Bank to act as Master Servicer under this Agreement and Discover Bank agrees to act as Master Servicer
under this Agreement. 
 (b) Subject to Section 10.01, the Master Servicer is hereby authorized and empowered (i) unless
such power and authority is revoked by the Trustee, to instruct the Trustee to make withdrawals and payments from the Investor Accounts in accordance with the instructions set forth in this Agreement and in the Series Supplements, (ii) to make
drawings on any Credit Enhancement as set forth in the Series Supplements, (iii) to make any filings or registrations with, and seek any consents or authorizations from, the Securities and Exchange Commission and any securities authority of any
jurisdiction on behalf of the Trust as may be necessary or advisable to comply with the securities or reporting requirements laws of the United States or any state or other jurisdiction and (iv) to take any other action and exercise any other
power permitted to be taken or exercised by the Master Servicer pursuant to the terms of this Agreement or any Series Supplement. The Trustee agrees that it shall promptly follow the written instructions of the Master Servicer to withdraw funds from
the Investor Accounts and make drawings under any Credit Enhancement as required by this Agreement or any applicable Series Supplement. The Trustee shall furnish the Master Servicer with any powers of attorney and other documents necessary or
appropriate under the laws of any jurisdiction with authority over the Receivables (or receivables in Charged-Off Accounts) to enable the Master Servicer to carry out its servicing and administrative duties hereunder. 

  
 34 

 (c) In the event that the Transferor is unable for any reason to transfer Receivables to the
Trust in accordance with the provisions of this Agreement (including, without limitation, by reason of the application of the provisions of Section 9.01 or any governmental agency having regulatory authority over the Transferor or any
court of competent jurisdiction ordering that the Transferor not convey any additional Principal Receivables to the Trust) then, in any such event, the Master Servicer agrees to allocate, after the date of such inability, all Collections with
respect to Principal Receivables, and all amounts that would have constituted Collections with respect to Receivables that would have been Principal Receivables but for the Transferor’s inability to transfer such Receivables (up to an aggregate
amount equal to the amount of the Principal Receivables in the Trust as of such date that were transferred to the Trust by the Transferor) in accordance with Section 2.09(c) and to apply such amounts as Collections in accordance with
Section 4.03; provided, however, that if the Master Servicer is unable pursuant to any Requirement of Law or otherwise to allocate payments on the Accounts as described above, the Master Servicer agrees that it shall, in
any such event, after such date allocate payments on the Accounts with respect to the principal balance of such Accounts first to the oldest principal balance of such Accounts. 

(d) The Master Servicer agrees that upon a request by the Transferor or the Trustee it will use its best efforts to obtain and maintain the
listing of the Investor Certificates of any Class of any Series on any specified securities exchange. If any such request is made, the Master Servicer shall give notice to the Transferor and the Trustee of the date on which such Investor
Certificates are approved for such listing and within three Business Days following receipt of notice by the Master Servicer of any actual, proposed or contemplated delisting of such Investor Certificates by any such securities exchange. The Trustee
or the Master Servicer, each in its sole discretion, may terminate any listing on any such securities exchange at any time subject to the notice requirements set forth in the preceding sentence. 

SECTION 3.02 Acceptance of Appointment and Other Matters Relating to Servicers. 

(a) In connection with and in consideration for the conveyance of the Receivables to the Trust by the Transferor, and the issuance of the
Transferor Certificate to the Transferor, Discover Funding as the Holder of the Transferor Certificate and the Trustee agree to cause (i) Discover Bank to act as Servicer with respect to Discover Card Accounts under this Agreement and Discover
Bank agrees to act as such Servicer under this Agreement and (ii) Discover Bank or an affiliate of Discover Bank to act as Servicer with respect to each type of account, other than Discover Card Accounts, which are designated as Additional
Accounts pursuant to Section 2.10 and Discover Bank or such affiliate of Discover Bank shall agree to act as such Servicer under this Agreement, pursuant to the Assignment of Additional Accounts with respect to such Accounts. 

(b) Each Servicer is hereby authorized in the name and on behalf of the Trustee and the Holder of the Transferor Certificate, and agrees, to
service and administer the Receivables (and receivables in Charged-Off Accounts) with respect to which it is acting as Servicer, and collect payments due under such Receivables (or amounts recovered from receivables in Charged-Off Accounts) in
accordance with its customary and usual servicing procedures for servicing credit receivables comparable to the Receivables (or such receivables in 

  
 35 

 
Charged-Off Accounts) and in accordance with its Credit Guidelines, and acting alone or through any party designated by it pursuant to Section 8.06, shall do any and all things in
connection with such servicing and administration that it may deem necessary or desirable. Without limiting the generality of the foregoing and subject to Section 10.02, each Servicer is hereby authorized and empowered (i) to
execute and deliver, on behalf of the Trust for the benefit of the Certificateholders but in its own name, without reference to the fact that it is acting for the Trust, any and all instruments of satisfaction or cancellation, or of partial or full
release or discharge, and all other comparable instruments, with respect to the Receivables (or receivables in Charged-Off Accounts) with respect to which it is acting as Servicer, (ii) after the delinquency of any such Receivable (or
receivable in a Charged-Off Account) and to the extent permitted under and in compliance with applicable law and regulations, to commence collection proceedings with respect to such Receivables (or receivables in Charged-Off Accounts) on behalf of
the Trust for the benefit of the Certificateholders but in its own name, without reference to the fact that it is acting for the Trust and (iii) subject to Section 3.02(e), to sell the receivables in any Charged-Off Account. The
Trustee shall furnish each Servicer with any powers of attorney and other documents necessary or appropriate under the laws of any jurisdiction with authority over the Receivables (or receivables in Charged-Off Accounts) to enable such Servicer to
carry out its servicing and administrative duties hereunder. 
 (c) No Servicer shall under any circumstances be obligated to use separate
servicing procedures, offices, employees or accounts for servicing Accounts from the procedures, offices, employees and accounts used by such Servicer in connection with servicing its other accounts. 

(d) Until such time as an additional Servicer shall be appointed in conjunction with the addition to the Trust of Additional Accounts that are
not Discover Card Accounts, Discover Bank shall act as Master Servicer and as the sole Servicer hereunder. Upon the appointment of any Servicer in addition to Discover Bank (or any Successor Master Servicer, as applicable), Discover Bank (or such
Successor Master Servicer, as applicable) and any such additional Servicer shall enter into a Master Servicing Agreement, which agreement shall set forth the respective rights and duties of the Master Servicer and each Servicer. 

(e) No Servicer may sell receivables in Charged-Off Accounts pursuant to Section 3.02(b)(iii) after March 31, 2001;
provided, however, that to the extent that the Trustee, on behalf of the Trust, entered into agreements with third parties on or before March 31, 2001 that permit the Trust to require, or obligate the Trust to accept, reassignment
of receivables in Charged-Off Accounts sold prior to March 31, 2001 pursuant to such agreements, and to substitute receivables in Charged-Off Accounts for such reassigned receivables, then the Trust shall be entitled to act under such
agreements and to substitute receivables for such reassigned receivables, such substitute receivables to be identified by the Master Servicer as meeting the requirements of such agreements; provided, further, however, that the
Master Servicer shall use its best efforts to identify an amount of substitute receivables that closely approximates the amount of reassigned receivables and that will satisfy the substitution requirements of any such agreement.

on the Trust, the Trustee or the Certificateholders. The Master Servicer shall be required to pay such expenses for its own account, and shall not be entitled to any payment therefor other than the Monthly Servicing Fee. 

(b) Use of Collections. Subject to Section 4.03(b), the Trustee on behalf of the Trust, with the consent of Discover

Agencies to the effect that such firm is of the opinion that the system of internal accounting controls in effect on the date of such statement relating to the servicing procedures performed by the Master Servicer and each Servicer under this
Agreement, taken as a whole, was sufficient for the prevention and detection of errors and irregularities which would be material to the assets of the Trust during the preceding fiscal year or transition period, as applicable, and that nothing has
come to their attention that would cause them to believe that such servicing has not been conducted in compliance with Sections 3.03, 4.03, 4.04, 4.05 and 8.07 of this Agreement

  
 40 

 
and the provisions relating to servicing or the allocation and payment of Collections in any Series Supplements, except for such exceptions as they believe to be immaterial and such other

RIGHTS OF INVESTOR CERTIFICATEHOLDERS AND 

ALLOCATION AND APPLICATION OF COLLECTIONS 

SECTION 4.01 Rights of Investor Certificateholders. Each Investor Certificate shall represent a Fractional Undivided Interest in the
Trust, including the right to receive the Collections and other amounts at the times and in the amounts specified herein and in the Series Supplements to be deposited in Investor Accounts or paid to the Investor Certificateholders and, with respect
to any particular Series, any additional rights set forth in the applicable Series Supplement; provided, however, that the aggregate interest represented by all Investor Certificates outstanding at any one time in the assets of the
Trust shall not exceed an amount equal to the Aggregate Invested Amount plus all accrued but unpaid Certificate Interest and any interest thereon. The Transferor Certificate shall represent a fractional undivided interest in the Trust,
including the right to receive the Collections and other amounts at the times and in the amounts specified herein and in the Series Supplements to be paid to the Holder of the Transferor Certificate. 

SECTION 4.02 Establishment and Administration of Investor Accounts. 

(a) Establishment of the Collections Account and the Group Collections Accounts. The Trustee, for the benefit of the
Certificateholders, shall cause to be established and maintained in the name of the Trust, with the corporate trust department of an office or branch of either the Trustee or a Qualified Institution, one non-interest bearing segregated trust account
designated the “Collections Account” and one additional non-interest bearing segregated trust account for each Group (each, a “Group Collections Account”), in each case marked to indicate clearly that the funds deposited
therein are held for the benefit of the Certificateholders. Subject to subsection (c) below, the Trust shall possess all right, title and interest in all funds on deposit from time to time in the Collections Account and each Group Collections
Account and in all proceeds thereof. Pursuant to authority granted to it pursuant to Section 3.01(b), the Master Servicer shall have the revocable power to instruct the Trustee to withdraw funds from the Collections Account and the Group
Collections Accounts for the purpose of carrying out the duties of the Master Servicer hereunder. The Master Servicer at all times shall maintain accurate records reflecting each transaction in the Collections Account and the Group Collections
Accounts. 
 (b) Establishment of Other Investor Accounts. The Trustee shall, from time to time, establish additional Investor
Accounts as provided in applicable Series Supplements. 
 (c) Administration of the Investor Accounts. Unless otherwise specified in
a relevant Series Supplement, any funds on deposit in any Investor Account for more than one Business Day shall at all times be invested in Permitted Investments at the written direction of the Master Servicer or its agent, subject to the
restrictions set forth below. The Trustee shall maintain, or cause to be maintained, for the benefit of the Certificateholders possession of the negotiable instruments or securities evidencing the Permitted Investments described in clause
(a) of the definition thereof from the time of purchase thereof until the time of sale or maturity. Any Permitted Investment with a stated maturity shall mature on or prior to the Distribution Date applicable to the Investor Account for which
the Permitted Investments are held related to the 

  
 42 

 
earliest Due Period in which Collections or Interchange invested in such Permitted Investments were received and any funds received with respect to the maturity of a Permitted Investment shall be
available in sufficient time to allow for any payments to be made to Investor Certificateholders on such Distribution Date. For purposes of the preceding sentence, withdrawals from the Collections Account pursuant to Section 4.03(c)
shall be deemed to be made from Collections and/or Interchange in the order in which such Collections and/or Interchange, as applicable, were deposited into the Collections Account. 

On each applicable Distribution Date, all interest and earnings (less investment expenses) on funds on deposit in any Investor Account (other
than any Series Principal Funding Accounts), if any, shall be deposited by the Trustee in a separate deposit account in the name of the Holder of the Transferor Certificate, which account shall not constitute a part of the Trust, or such interest
and earnings shall otherwise be turned over by the Trustee to the Holder of the Transferor Certificate not less frequently than monthly. For purposes of determining the availability of funds or the balances in such Investor Accounts for any reason
under this Agreement or any Series Supplement, all investment earnings on such funds shall be deemed not to be available or on deposit. 

SECTION 4.03 Collections and Allocations. 

(a) Collections and Interchange. The Master Servicer shall apply all Collections received during and Interchange for each Due Period as
described in this Section 4.03 and any applicable Series Supplements. 
 (b) Daily Collections. If, at any time, either
(i) with respect to any Accounts, the then current Servicer with respect to such Accounts does not have a short-term debt rating of at least A-1 by Standard & Poor’s and P-1 by Moody’s (if the then current Servicer is the
original Servicer with respect to such Accounts or an affiliate of the original Servicer) or a short-term debt rating of at least A-1+ by Standard & Poor’s and P-1 by Moody’s (if the then current Servicer with respect to such
Accounts is not the original Servicer or an affiliate of the original Servicer) or (ii) the conditions specified in clause (i) or pursuant to this clause (ii) are superseded by any conditions subsequently agreed to in writing by
Discover Funding as the Holder of the Transferor Certificate and any Rating Agency, and any of such subsequently agreed to conditions occurs; then, as promptly as possible after each Date of Processing with respect to the Receivables serviced by the
applicable Servicer occurring on and after such event, but in no event later than two Business Days following such Date of Processing, such Servicer shall pay to, or at the direction of, the Master Servicer, for deposit into the Collections Account,
from the Collections received by such Servicer on or after the date of such event and recorded on such Date of Processing, an amount equal to the sum of the Required Daily Deposits with respect to such Servicer for each Series then outstanding with
respect to such Date of Processing; provided, that if the first such deposit occurs following a period during which such Servicer has been using Collections in accordance with Section 3.03(b), then, on the sixth Business Day
following the event giving rise to the making of Required Daily Deposits by such Servicer, in addition to the Required Daily Deposits for that day, such Servicer shall pay to, or at the direction of, the Master Servicer, the amount that would have
been on deposit in the Collections Account with respect to such Servicer had such Servicer been making the Required Daily Deposits since the beginning of the Due Period, less any amounts previously so paid or deposited. Amounts made available to any
Servicer pursuant to Section 3.03 shall be repayable upon the occurrence of the conditions in this Section 4.03(b) in the manner and to the extent set forth herein. 

  
 43 

 (c) Deposits with Respect to Each Distribution Date. 

(i) On or before each Distribution Date, the Master Servicer shall deposit into the Collections Account that portion of
Collections, Interchange and Recovered Amounts with respect to the related Due Period that are to be allocated on such Distribution Date and that have not previously been deposited into the Collections Account. 

(ii) On or before each Distribution Date, the Master Servicer shall direct the Trustee in writing to withdraw from the
Collections Account and pay to Discover Funding as the Holder of the Transferor Certificate an amount equal to that portion of the sum of (x) the total amount of Finance Charge Collections for the related Due Period less the sum of the amount
of Series Finance Charge Collections for each Series then outstanding for the related Due Period, (y) the amount of Principal Collections for the related Due Period less the sum of the amount of Series Principal Collections for each Series then
outstanding for the related Due Period and (z) the total amount of Interchange for the related Due Period less the sum of the amount of Series Interchange for each Interchange Series then outstanding for the related Due Period, that is to be
allocated to the Holder of the Transferor Certificate on such Distribution Date. 
 (iii) On or before each Distribution
Date, after giving effect to the payments made pursuant to clause (ii) above with respect to such Distribution Date, the Master Servicer shall direct the Trustee in writing to withdraw from the Collections Account and pay to each Group

Group and (z) the sum of the Series Interchange for each Interchange Series that is a member of such Group. 
 (iv)
Amounts on deposit in each Group Collections Account shall be distributed on or before each Distribution Date with respect to each such Group in accordance with the terms of the Series Supplements for each Series then outstanding. 

(d) Aggregate and Net Payments. All payments made pursuant to this Agreement or any Series Supplement on or before any Trust
Distribution Date or Distribution Date on which Discover Bank is the Master Servicer, between the Master Servicer or the Holder of the Transferor Certificate and the Investor Accounts, may be aggregated for such Trust Distribution Date or
Distribution Date such that Discover Bank, acting as Master Servicer and as agent of the Holder of the Transferor Certificate, may make only one payment to each applicable account in satisfaction of all payments of the Holder of the Transferor
Certificate and the Master Servicer pursuant to this Agreement and all Series Supplements for Series then outstanding, to the extent that all payment obligations of the Master Servicer and of the Holder of the Transferor Certificate to each
applicable account on such Trust Distribution Date or Distribution Date exceed all payment obligations of each such account to the Master Servicer and the Holder of the 

  
 44 

 
Transferor Certificate on such Trust Distribution Date or Distribution Date. Any amounts payable on a given Trust Distribution Date to the Holder of the Transferor Certificate pursuant to
Section 4.03(c)(ii) hereof, or on a Distribution Date to the Master Servicer with respect to Monthly Servicing Fees pursuant to the provisions of any Series Supplement then outstanding, shall be deemed to have been paid if, and to the
extent, Discover Bank (as Servicer) already is in possession of such amounts on such Distribution Date (or was in possession of such amounts for more than two Business Days during the related Due Period) as a result of its permitted use of
Collections and Interchange during the prior Due Period pursuant to Section 3.03(b) and in accordance with the definition of “Required Daily Deposit” (as defined in the relevant Series Supplement), except to the extent Discover
Bank has deposited such amounts into the Collections Account. 
 Notwithstanding the other provisions of this Section 4.03 and the
applicable provisions of any Series Supplement then outstanding, the allocations of Collections and Interchange pursuant to Section 4.03(c) and the applicable provisions of any Series Supplements then outstanding shall be deemed to be made on
the date on which the Master Servicer delivers the Servicer’s Monthly Statement and the information required to be included in the Investor Certificateholders’ Monthly Statement with respect to each Series then outstanding to the Trustee.
The Trustee is hereby authorized, upon receipt of the Servicer’s Monthly Statement and the information required to be included in the Investor Certificateholders’ Monthly Statement with respect to each Series then outstanding, together
with written instructions from the Master Servicer, to immediately transfer to Discover Funding as the Holder of the Transferor Certificate or the Master Servicer, as applicable, any funds in any Investor Account that would otherwise be paid to
Discover Funding as the Holder of the Transferor Certificate or the Master Servicer, as applicable, on the Trust Distribution Date or any Distribution Date related to such Due Period. 

SECTION 4.04 Transferor’s or Master Servicer’s Failure to Make a Deposit or Payment. 

(a) If the Master Servicer or the Transferor fails to make, or give instructions to make, any payment or deposit (other than as required by
Section 2.05(b), 2.06(b) or 2.07(b) or in connection with Section 12.02) required to be made or given by the Master Servicer or the Transferor, respectively, at the time specified in this Agreement (including
applicable grace periods), the Trustee shall make such payment or deposit from the applicable Investor Account without instruction from the Master Servicer or the Transferor (or, to the extent that sufficient funds are not available in the
applicable Investor Account to make such payment and the relevant Series Supplement provides for Credit Enhancement for such purpose, shall make a drawing from the available Credit Enhancement, if any); provided, that the Trustee shall be
required to make such payment, deposit or draw only to the extent it has sufficient information to allow it to determine the amount thereof, which information the Trustee shall be deemed to have with respect to the amount of Certificate Interest
payable on each Distribution Date. The Master Servicer shall, upon request of the Trustee, promptly provide the Trustee with all information necessary to allow the Trustee to make such a payment, deposit or draw. Such funds or the proceeds of such
drawing shall be applied by the Trustee in the same manner in which such payment or deposit should have been made by the Transferor or the Master Servicer, as the case may be. 

(b) If a drawing from a Credit Enhancement is made pursuant to this Section 4.04 in lieu of a deposit or payment from the
applicable Investor Account, the Master Servicer or the Transferor, as the case may be, shall, as promptly as practicable and from the appropriate source, make the required payment, deposit or transfer or give the Trustee instructions to transfer
the required payment or deposit in respect of which such drawing was made to reinstate the Credit Enhancement, as set forth in any applicable Series Supplement. 

  
 45 

 SECTION 4.05 Adjustments For Miscellaneous Debits and Credits and Fraudulent
Charges. 
 (a) With respect to any Receivable to which any adjustment without payment by or on behalf of an Obligor has been
made (an “Adjustment”) including, but not limited to, any Receivable that (1) was created as a result of a fraudulent or counterfeit charge, (2) the Servicer with respect to such Receivable otherwise adjusts, increases,
reduces, modifies or cancels in accordance with the applicable Credit Guidelines without receiving cash or other payment therefor by the Obligor with respect to such Receivable, (3) was created in respect of merchandise returned by the Obligor
thereunder, or (4) was created or cancelled through an Account Combination, Discover Funding, as the Holder of the Transferor Certificate, shall increase or reduce, as the case may be, the aggregate amount of Receivables. 

(b) In the event that the exclusion of the amount of an Adjustment from the calculation of the Transferor Interest would cause the Transferor
Interest to be an amount less than zero, Discover Funding as the Holder of the Transferor Certificate shall, no later than the Business Day following the last day of the Due Period during which such Adjustment is made, make a deposit into the
Collections Account in immediately available funds in an amount equal to the amount by which such Adjustment causes the Transferor Interest to be less than zero. Such deposit shall be applied as a Collection in accordance with
Section 4.03. 
 SECTION 4.06 Reallocation of Series Among Groups. The Master Servicer may elect, at any time, by written
notice to the Trustee and to Discover Funding as the Holder of the Transferor Certificate, and subject to the conditions set forth below, to move any Series from the Group of which it is then a member to any other Group, including without limitation
to a new Group established at such time of which the Series to be moved is the only Series. Any such election by the Master Servicer shall become effective on the day specified in the notice of such election. 

The Master Servicer may make such election only if the following conditions are satisfied: (i) a Series may only be moved from one Group
to another Group if the Series in both Groups have the same Distribution Date; (ii) the Master Servicer shall have delivered to the Trustee a certificate to the effect that the Master Servicer reasonably believes that the movement of the
applicable Series would not (x) result in any delay in the payment of principal to the Investor Certificateholders of any Series then outstanding, or (y) cause an Amortization Event to occur with respect to any Series then outstanding; and
(iii) the Rating Agencies shall have advised the Master Servicer and Discover Funding as the Holder of the Transferor Certificate that the movement of the applicable Series would not cause the rating of any Class of any Series then outstanding
to be lowered below the Required Rating or withdrawn.

subject to any applicable withholding or deduction imposed pursuant to the Internal Revenue Code or other applicable tax law, including foreign withholding and deduction. Each Certificateholder and Certificate Owner shall provide the Indenture
Trustee, Paying Agent, the Trust or other person responsible for withholding or deduction of taxes with the Tax Information, and agrees to update such Tax Information promptly upon request of the Indenture Trustee, Paying Agent, the Issuer or other

Certificateholder and Certificate Owner, as applicable. 
 (b) If the Trust is required to be treated as a partnership and to the extent
that subchapter C of chapter 63 of subtitle F of the Code would otherwise apply to the Trust after 2017, the partnership representative (described below) on behalf of the Trust, shall timely elect any available election under Sections 6221 through
6241 of the Code that results in any imputed underpayment to be paid by the “partners” (as described in Section 6226 of the Code). In the event that a “tax matters partner” (within the meaning of Section 6231(a)(7) of

Transferor (or a U.S. Affiliate of the Transferor if the Transferor is ineligible) is hereby designated as tax matters partner or partnership representative, as applicable. Each registered owner of and, if different, each owner of a beneficial
interest in a Certificate that did not receive an Opinion of Counsel to the effect that such interest was properly characterized as debt at the time of its issuance shall promptly provide the Trust and partnership representative with any requested
information, documentation or material to enable the Trust to make any of the elections described in this section and otherwise comply with Sections 6221 through 6241 of the Code.

of $1,000 per Investor Certificate, aggregated for such calendar year or the applicable portion thereof during which such Person was an Investor Certificateholder, together with such other customary information as the Trustee or the Master Servicer
deems necessary or desirable to enable the Investor Certificateholders to prepare their tax returns. Such obligation of the Paying Agent shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided

 ARTICLE VI. 

THE INVESTOR CERTIFICATES 

SECTION 6.01 The Certificates. 

(a) The Investor Certificates of any Series or Class may be issued, subject to applicable laws and regulations, in fully registered form
(“Registered Certificates”) and shall be substantially in the form of the exhibits with respect thereto attached to the applicable Series Supplement. The Transferor may elect at any time, by written notice to the Trustee, to have
its fractional undivided interest in the Trust be (i) evidenced by a certificate or (ii) an uncertificated interest. If the Holder of the Transferor Certificate elects to have its fractional undivided interest in the Trust be
uncertificated, it shall deliver to the Trustee for cancellation any certificate previously issued. If the Holder of the Transferor Certificate elects to have its fractional undivided interest in the Trust be evidenced by a certificate, such
certificate shall be issued pursuant hereto, substantially in the form of Exhibit D, and shall upon issue be executed and delivered by the Holder of the Transferor Certificate to the Trustee for authentication and redelivery as provided in
Sections 2.02 and 6.03. Except as otherwise provided in any Series Supplement or in Section 6.11, Registered Certificates shall be issued in minimum denominations of $1,000 Fractional Undivided Interests and in integral
multiples of $1,000 in excess thereof. If specified in any Series Supplement, the Investor Certificates of any Series or Class shall be issued upon initial issuance as a single certificate evidencing the Series Initial Investor Interest or Class
Initial Investor Interest, as applicable, as described in Section 6.11. 

  
 48 

 
The Transferor Certificate shall represent the entire Transferor Interest. The Certificates shall be executed on behalf of the Trust by Discover Funding as the Holder of the Transferor
Certificate by any authorized officer. The signature of any of these officers on the Certificates may be manual or facsimile. 
 (b)
Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Transferor shall not become invalid, notwithstanding that such individuals or any of them have ceased to hold such offices prior
to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. 
 (c) No Certificate
shall be entitled to any benefit under this Agreement (or any Series Supplement), or be valid or obligatory for any purpose unless there appears on such Certificate a certificate of authentication substantially in the form attached to Exhibit
D hereto (in the case of any certificated Transferor Certificate) or attached to the appropriate exhibits to a Series Supplement, as applicable, executed by the Trustee by manual signature, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder and is entitled to the benefits of this Agreement and the relevant Series Supplement. All Registered Certificates and any
certificated Transferor Certificate shall be dated the date of their authentication. 
 SECTION 6.02 Book-Entry Certificates. 

(a) The Investor Certificates, upon original issuance, shall be issued in fully registered form, in the form of one or more typewritten
Certificates representing the Book-Entry Certificates, to be delivered to The Depository Trust Company, the initial Clearing Agency, by, or on the behalf of, the Transferor. The Investor Certificates shall initially be registered in the Certificate
Register in the name of CEDE & Co., the nominee of the initial Clearing Agency, or any successor nominee designated by The Depository Trust Company or any successor Clearing Agency, and no Certificate Owner will receive a definitive
certificate representing such Certificate Owner’s interest in the Investor Certificates, except as provided in Section 6.02(c). Unless and until definitive, fully registered Investor Certificates (“Definitive
Certificates”) have been issued to the beneficial owners of the Investor Certificates pursuant to Section 6.02(c): 

(i) the provisions of this Section 6.02(a) shall be in full force and effect; 

(ii) the Transferor, the Master Servicer and the Trustee may deal with the Clearing Agency and the Clearing Agency Participants
for all purposes (including the making of distributions on the Investor Certificates) as the authorized representatives of the Certificate Owners; 

(iii) to the extent that the provisions of this Section 6.02(a) conflict with any other provisions of this
Agreement, the provisions of this Section 6.02(a) shall control; and 
 (iv) the rights of Certificate Owners
shall be exercised only through the Clearing Agency and the Clearing Agency Participants and shall be limited to those established by law and agreements between such Certificate Owners and the Clearing

  
 49 

 
Agency and/or the Clearing Agency Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 6.02(c), the initial
Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal and interest on the Investor Certificates to such Clearing Agency Participants. 

For purposes of any provision of this Agreement or any applicable Series Supplement requiring or permitting actions with the consent of, or at
the direction of, Investor Certificateholders evidencing a specified percentage of the Class Invested Amount of any Class, such direction or consent may be given by Certificate Owners (acting through the Clearing Agency and the Clearing Agency
Participants). 
 (b) Whenever notice or other communication is required to be given to Investor Certificateholders of any Class with
respect to which Book-Entry Certificates have been issued, unless and until Definitive Certificates shall have been issued to the related Certificate Owners pursuant to Section 6.02(c), the Trustee shall give all such notices and
communications specified herein to be given to such Investor Certificateholders to the Clearing Agency. 
 (c) If, with respect to any
Series the Investor Certificates of which are originally issued in the form of Book-Entry Certificates: 
 (i) (A) the Master
Servicer advises the Trustee in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities under the Depository Agreement, and (B) the Trustee or the Master Servicer is unable to locate a qualified
successor, 
 (ii) the Master Servicer, at its option, advises the Trustee in writing that it elects to terminate the
book-entry system with respect to such Series through the Clearing Agency, or 
 (iii) after the occurrence of a Master
Servicer Termination Event, Certificate Owners representing beneficial interests aggregating not less than 51% of the Invested Amount of any Class of such Series advise the Trustee and the Clearing Agency through the Clearing Agency Participants in
writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Certificate Owners of such Class, 

then the Trustee shall notify all Certificate Owners of each Class of such Series upon the occurrence of an event described in clauses (i) and
(ii) above or all Certificate Owners of the applicable Class upon the occurrence of the event described in clause (iii) above, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive
Certificates to Certificate Owners of such Class of such Series requesting the same. Upon surrender to the Trustee of the applicable Investor Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for
registration, the Trustee shall issue the Definitive Certificates for the applicable Class. Neither the Transferor nor the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of Definitive 

  
 50 

 
Certificates all references herein to obligations imposed upon or to be performed by the Clearing Agency with respect to the applicable Class of the applicable Series of Investor Certificates
shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates, and the Trustee shall recognize the Holders of such Definitive Certificates as Certificateholders hereunder. 

SECTION 6.03 Authentication of Certificates. If the Holder of the Transferor Certificate elects to have its fractional undivided
interest in the Trust evidenced by a certificate pursuant to Section 6.01, the Trustee shall authenticate and deliver the Transferor Certificate to the Holder of the Transferor Certificate. From time to time after the Initial Closing
Date, pursuant to Section 6.06 hereof and the terms of the applicable Series Supplement, the Trustee shall authenticate and deliver the Investor Certificates of additional Series (with the designation provided in the applicable Series
Supplement), upon the order of Discover Funding as the Holder of the Transferor Certificate, to the persons designated in such Series Supplement. If specified in the related Series Supplement, the Trustee shall authenticate and deliver outside the
United States a Global Certificate representing the Series Initial Investor Interest for such Series or the Class Initial Investor Interest for a specified Class of such Series. The Investor Certificates of each Series shall be duly authenticated by
or on behalf of the Trustee as provided herein and in the applicable Series Supplement, in authorized denominations equal to (in the aggregate) the Series Initial Investor Interest of each Series. At any time, the Investor Certificates outstanding
at such time, together with the Transferor Certificate, shall evidence the entire ownership of the Trust. 
 SECTION 6.04 Registration of
Transfer and Exchange of Certificates. 
 (a) (i) Discover Funding as the Holder of the Transferor Certificate shall keep or cause to be
kept by a transfer agent (“Transfer Agent”) a register for the Registered Certificates issued pursuant to this Agreement and the Series Supplements for all Series then outstanding (the “Certificate Register”) at any
office or agency of the Transferor to be maintained in accordance with the provisions of Section 6.04(c) in which, subject to such reasonable regulations as it may prescribe, the Transferor shall provide for the registration and transfer
of Registered Certificates. The Certificate Register shall be in written form or capable of being converted into written form within a reasonable time. Unless otherwise specifically designated by Discover Funding as the Holder of the Transferor
Certificate in a written notice to the Trustee, the Certificate Register shall be maintained at the Corporate Trust Office. 
 (ii) Investor
Certificates of certain Classes of certain Series may be ineligible for purchase by an employee benefit plan, trust or account subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or described in
Section 4975(e)(l) of the Code, and not excepted under Section 4975(g) (a “Plan”). No transfer of such an Investor Certificate shall be made nor shall any interest therein be transferred to a Plan. Each Holder of such a
Certificate, by its acceptance thereof, shall be deemed to represent and warrant that it is not (i) an employee benefit plan (as defined in Section 3(3) of ERISA) that is subject to the provisions of Title I of ERISA, (ii) a plan
described in Section 4975(e)(l) of the Code, and not excepted under Section 4975(g) or (iii) an entity that is using assets to purchase such Certificates that constitute plan assets by reason of a plan’s investment in such
entity. The Series Supplement with respect to each Series shall set forth which Class or Classes of such Series, if any, shall be subject to the restrictions set forth in this Section 6.04(a)(ii). 

  
 51 

 (iii) Upon surrender for registration of transfer of any Registered Certificate at any office or
agency to be maintained in accordance with the provisions of Section 6.04(c), Discover Funding as the Holder of the Transferor Certificate shall execute, and the Trustee shall authenticate and deliver, in the name of the designated

(iv) At the option of a Holder of a Registered Certificate, such Holder’s Registered Certificates may be exchanged for other Registered
Certificates of the same Class and Series, of a like Fractional Undivided Interest and bearing a number not contemporaneously outstanding upon surrender of the Registered Certificates to be exchanged at any such office or agency. Whenever any
Registered Certificates are so surrendered for exchange, Discover Funding as the Holder of the Transferor Certificate shall execute, and the Trustee shall authenticate and deliver the Registered Certificates which the Holder making the exchange is
entitled to receive. Registered Certificates may not be exchanged for certificates in bearer form. 
 (v) [Reserved]. 

(vi) The preceding provisions of this Section notwithstanding, the Transfer Agent shall not be required to register the transfer of or
exchange any Certificate for a period of 15 days preceding any Payment Date with respect to the Certificate. 
 (vii) Every Registered
Certificate presented or surrendered for registration of transfer or for exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Transferor and the Trustee duly executed, by the
Certificateholder thereof or his attorney duly authorized in writing. 
 (viii) No service charge shall be made for any registration of
transfer or exchange of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Certificates. 

(ix) All Investor Certificates surrendered for registration of transfer and exchange or for payment shall be canceled and disposed of in a
manner satisfactory to the Trustee. The Trustee shall cancel and destroy any Global Certificate upon its exchange in full for Definitive Euro-Certificates and shall deliver a certificate of destruction to the Transferor. Such certificate shall also

 (b) It is the understanding of the parties to this Agreement that Discover Bank has particular
expertise in performing the functions given by this Agreement to the Master Servicer and that the Investor Certificateholders will be purchasing the Investor Certificates relying on Discover Bank exercising such expertise in performing such
functions. Except as provided in Sections 8.04 and 8.06, the Master Servicer is not permitted to resign or delegate its duties and the parties understand that the Master Servicer’s performance of its functions and the quality of
the Receivables will best be ensured if the Transferor, as a wholly-owned subsidiary of Discover Bank, retains the Transferor Certificate. Accordingly (subject to the condition that the Transferor shall at all times retain sole control over its
properties and except as provided in Section 7.02), the Transferor Certificate shall not be transferred, assigned, exchanged, or otherwise conveyed except as provided in Section 7.05. 

(c) The Transferor will maintain at its expense in the Borough of Manhattan, The City of New York, and, if and so long as any Class of any
Series is listed on the Luxembourg Stock Exchange and such exchange shall so require, in Luxembourg, an office or offices or agency or agencies where Investor Certificates may be surrendered for registration of transfer or exchange. 

SECTION 6.05 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If any mutilated Certificate is surrendered to the Trustee, Discover Funding as the Holder of the Transferor Certificate shall execute and

(b) If there shall be delivered to Discover Funding as the Holder of the Transferor Certificate and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Certificate and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to Discover Funding
as the Holder of the Transferor Certificate or the Trustee that such Certificate has been acquired by a bona fide purchaser, Discover Funding as the Holder of the Transferor Certificate shall execute and, upon its request, the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Certificate, a Certificate of the same Class and Series, of a like fractional undivided interest and bearing a number not contemporaneously outstanding. 

(c) Upon the issuance of any Certificate pursuant to this Section, the Transferor may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto and any other expenses, including counsel fees, of the Transferor and the Trustee, and any Paying Agent or Transfer Agent connected therewith, and in addition a further sum not
exceeding two dollars for each Certificate so issued in substitution. 
 (d) Every Certificate issued pursuant to this Section in lieu of
any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Trust, whether or not the destroyed, lost or stolen Certificate shall be at any time enforceable by anyone, and shall be entitled to all
the benefits of this Agreement and the applicable Series Supplement equally and proportionately with any and all other Certificates of the same Class and Series duly issued hereunder. 

  
 53 

 SECTION 6.06 Issuances of New Series. 

(a) The Transferor may direct the Trustee to issue, from time to time, one or more Series subject to the conditions described below (each such
issuance, a “New Issuance”). The Transferor may effect a New Issuance by notifying the Trustee, in writing, at least three days in advance of the date upon which the New Issuance is to occur. Any notice of the New Issuance shall
state the designation of any Series to be issued on the date of the New Issuance and, with respect to each such Series: (i) its Series Initial Investor Interest, (ii) the Certificate Rate of each Class or Subclass, if applicable, of such
Series; (iii) its Payment Dates and the date from which interest shall accrue; (iv) its Series Termination Date and (v) any other terms that the Transferor sets forth in such notice of a New Issuance; provided, however,
that any notice of a New Issuance with respect to any Series that issues only collateral certificates to an entity or entities that will issue securities supported by, among other things, such collateral certificates, shall, in lieu of stating the
information in clauses (i) through (v) above, attach a copy of the Series Supplement therefor, in a form substantially agreed upon by the Transferor, the Master Servicer, the Servicers and the Trustee. On the date of the New Issuance, the
Trustee shall authenticate and deliver any such Series only upon satisfaction of the following conditions: (a) Discover Funding as the Holder of the Transferor Certificate shall have delivered to the Trustee a Series Supplement executed by the
Transferor, the Master Servicer, the Servicers and the Trustee that specifies the terms of such Series, (b) the Transferor shall have delivered to the Trustee written confirmation from the Rating Agencies that the New Issuance will not result
in the reduction below or withdrawal of the Required Ratings of any Class of any Series then outstanding rated by each Rating Agency, (c) the Transferor shall have delivered to the Trustee and the Rating Agencies (A) with respect to each
New Issuance, an opinion of counsel dated as of the date of such New Issuance to the effect that, although not free from doubt, the Investor Certificates of such New Issuance will be treated as indebtedness of the Transferor for federal income and
Delaware (and any other state where substantial servicing activities are conducted by an Additional Originator with respect to Accounts serviced by such Additional Originator, or by Discover Bank if there is a substantial change from Discover
Bank’s present servicing activity, if any, in such state) state income or franchise tax purposes; provided, however, such opinion shall not be required for any New Issuance with respect to any Series that issues only collateral
certificates to an entity or entities that will issue securities supported by, among other things, such collateral certificates; and provided, further, such opinions described in this clause (c)(A) shall not be required for any New
Issuance issued to an entity that is disregarded for federal income tax purposes and is directly and wholly owned by Discover Bank and (B) with respect to each New Issuance other than the New Issuance related to the first Series issued by the
Trust, an opinion of counsel dated as of the date of such New Issuance to the effect that such New Issuance will not adversely affect the conclusion set forth in any prior opinion of counsel delivered pursuant to this clause (c) as to the
treatment of the Investor Certificates of any such prior Series as indebtedness of the Transferor or as to the treatment of the Trust as a mere security device and (d) Discover Funding as the Holder of the Transferor Certificate shall not be
required to designate Additional Accounts or convey Participation Interests to the Trust 

  
 54 

 
pursuant to Section 2.10(a) as a result of such New Issuance. The Series Supplement with respect to any New Issuance may modify or amend the terms of this Agreement, provided,
that such modifications or amendments shall apply solely with respect to such Series. Upon satisfaction of such conditions, the Trustee shall issue, as provided in Section 6.06(d), such Series of Investor Certificates dated as of the

subordinated Series. 
 (c) The Transferor may designate that one or more Groups be subordinate in right of payment, in whole or in part, to
one or more other Groups, whether or not the Series in any such subordinate Group are issued contemporaneously with the Series in any non-subordinate Group. The manner and extent to which any Group shall be subordinated to any other Group shall be

 (d) Upon any New Issuance, Discover
Funding as the Holder of the Transferor Certificate shall execute and deliver to the Trustee, and the Trustee shall authenticate pursuant to Section 6.03, one or more Series of Investor Certificates. The Investor Certificates of any such
Series shall be substantially in the form specified in the applicable Series Supplement and shall each bear, upon its face, the designation for such Series. 

SECTION 6.07 Persons Deemed Owners. Prior to due presentation of a Certificate for registration of transfer or exchange, the Trustee,
the Paying Agent, the Transfer Agent and any agent of any of them may treat the person in whose name any Registered Certificate is registered as the owner of such Registered Certificate for the purpose of receiving distributions pursuant to
Section 5.01 and for all other purposes whatsoever; and neither the Trustee, the Paying Agent, the Transfer Agent nor any agent of any of them shall be affected by any notice to the contrary. 

SECTION 6.08 Appointment and Duties of Paying Agent. 

(a) The Paying Agent shall make distributions to Investor Certificateholders from the Series Distribution Accounts, the Series Interest
Funding Accounts and the Series Principal Funding Accounts pursuant to Section 5.01 and the relevant provisions of the applicable Series Supplement. Any Paying Agent shall have the revocable power to withdraw funds from the Series
Distribution Accounts, the Series Interest Funding Accounts and the Series Principal Funding Accounts for the purpose of making the distributions referred to above. The Trustee may revoke such power and remove the Paying Agent if the Trustee
determines in its sole discretion that the Paying Agent shall have failed to perform its obligations under this Agreement or any Series Supplement in any material respect. The Paying Agent shall initially be the Trustee and any co-paying agent or
paying agencies chosen by the Paying Agent and acceptable to the Trustee and the Transferor, including, if and for so long as any Class of any Series is listed on the Luxembourg Stock Exchange and such exchange so requires, a co-paying

  
 55 

 
agent or paying agency in Luxembourg or another city in western Europe. The Trustee shall be permitted to resign as Paying Agent upon 30 days’ written notice to the Transferor and upon the
appointment of a successor to act as Paying Agent. For so long as the Trustee shall act as Paying Agent, the provisions of Sections 11.01, 11.02 and 11.03 shall apply to the Trustee in its role as Paying Agent. 

(b) The Trustee shall cause any Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee that such Paying Agent will 
 (i) hold all sums held by it for payment to the Investor
Certificateholders in trust for the benefit of the Investor Certificateholders entitled thereto until such sums shall be paid to such Investor Certificateholders; 

(ii) comply with all requirements of the Internal Revenue Code or any other applicable tax law with respect to the withholding
from any payments made by it on any Certificates of any applicable withholding taxes imposed thereon, including FATCA Withholding Tax (including obtaining and retaining from Persons entitled to payments with respect to the Certificates any Tax
Information and making any withholdings with respect to the Notes as required by the Internal Revenue Code (including FATCA) and paying over such withheld amounts to the appropriate governmental authority); and 

(iii) comply with any applicable reporting requirements in connection with any payments made by it on any Certificates and any

 SECTION 6.09 Access to List of Names and
Addresses of Holders of Registered Certificates. The Trustee will furnish or cause to be furnished by the Transfer Agent to the Master Servicer or the Paying Agent, within five Business Days after receipt by the Trustee of a request therefor
from the Master Servicer or the Paying Agent, respectively, in writing, a list in such form as the Master Servicer or the Paying Agent may reasonably require, of the names and addresses of the Holders of Registered Certificates of any Class or
Series as of the most recent Record Date for payment of distributions to such Holders of Registered Certificates. If three or more Holders of Registered Certificates of any Class of any Series (the “Applicants”) representing
Fractional Undivided Interests aggregating not less than 5% of the Series Invested Amount of any Series apply in writing to the Trustee, and such application states that the Applicants desire to communicate with other Holders of Registered
Certificates of such Class of such Series, or such Series, with respect to their rights under this Agreement, the relevant Series Supplement or the Investor Certificates and is accompanied by a copy of the communication which such Applicants propose
to transmit, then the Trustee, after having been adequately indemnified by such Applicants for its costs and expenses, shall afford or shall cause the Transfer Agent to afford such Applicants access during normal business hours to the most recent
list of Holders of Registered Certificates of such Class of such Series, or such Series, held by the Trustee, within five Business Days after the receipt of such application. Such list shall be as of a date no more than 45 days prior to the date of
receipt of such Applicants’ request. Every Holder of a Registered Certificate, by receiving and holding such Certificate, agrees with the Trustee that neither the Trustee, the Transfer Agent, nor any of their respective agents shall be held

  
 56 

 
accountable by reason of the disclosure of any such information as to the names and addresses of such Certificateholders hereunder, regardless of the source from which such information was
derived. 
 SECTION 6.10 Authenticating Agent. 

(a) The Trustee may appoint one or more authenticating agents with respect to one or more Series which shall be authorized to act on behalf of
the Trustee in authenticating the Certificates of such Series in connection with the issuance, delivery, registration of transfer, exchange or repayment of such Certificates. Wherever reference is made in this Agreement to the authentication of
Certificates by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication on behalf of the Trustee by an authenticating agent and a certificate of authentication executed on behalf of
the Trustee by an authenticating agent. Each authenticating agent must be acceptable to the Transferor. 
 (b) Any institution succeeding to
the corporate agency business of an authenticating agent shall continue to be an authenticating agent without the execution or filing of any paper or any further act on the part of the Trustee or such authenticating agent. 

(c) An authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Transferor. The Trustee
may at any time terminate the agency of an authenticating agent by giving notice of termination to such authenticating agent and to the Transferor. Upon receiving such a notice of resignation or upon such a termination, or in case at any time an
authenticating agent shall cease to be acceptable to the Trustee or the Transferor, the Trustee promptly may appoint a successor authenticating agent. Any successor authenticating agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an authenticating agent. No successor authenticating agent shall be appointed unless acceptable to the Trustee and the Transferor.

 (d) The Trustee agrees to pay to each authenticating agent from time to time reasonable compensation for its services under this
Section 6.10, and the Trustee shall be entitled to be reimbursed and the Master Servicer shall reimburse the Trustee for such payments, subject to the provisions of Section 11.05. 

(e) The provisions of Sections 11.01, 11.02 and 11.03 shall be applicable to any authenticating agent. 

(f) Pursuant to an appointment made under this Section 6.10, the Certificates of an applicable Series may have endorsed thereon, in lieu

 SECTION 6.11 Global Certificate; Exchange Date. 

(a) If specified in the related Series Supplement for any Series or Class, the Investor Certificates of such Series or Class, as applicable,
will initially be issued as a single temporary global certificate (the “Global Certificate”), in the denomination of the Series Initial Investor Interest or the Class Initial Investor Interest, as applicable, and substantially in
the form set forth in the exhibit with respect thereto attached to the related Series Supplement. The Global Certificate will be authenticated by the Trustee upon the same conditions, in substantially the same manner and with the same effect as the
Definitive Certificates. The Global Certificate may be exchanged as described below for Registered Certificates in definitive form (the “Definitive Euro-Certificates”). 

(b) The Manager shall advise the Trustee, the Transferor, the Common Depositary, Clearstream Banking and Euroclear of the Exchange Date. The
Global Certificate may be exchanged for Definitive Euro-Certificates only on or after the Exchange Date. A United States institutional investor may exchange the portion of the Global Certificate beneficially owned by it only for an equal aggregate
principal amount of Registered Certificates bearing the applicable legend set forth in the form of Registered Certificate attached to the related Series Supplement and having a minimum denomination of $500,000. The Transferor may waive the $500,000
minimum denomination requirement if they so elect. Upon any demand for exchange for Definitive Euro-Certificates in accordance with this paragraph, the Transferor shall cause the Trustee to authenticate and deliver the Definitive Euro-Certificates
to the Holder according to the instructions of the Holder, in the case of Registered Certificates, but in either case only upon presentation to the Trustee of a written statement with respect to the Global Certificate or portion thereof being
exchanged signed by Clearstream Banking or Euroclear and dated on or after the Exchange Date, to the effect that it has received in writing or by tested telex a certification substantially in the form of Exhibit H signed by the Manager which
sold the relevant Certificates. Upon receipt of such certification, the Trustee shall cause the Global Certificate to be endorsed in accordance with paragraph (d) below. Any exchange as provided in this Section shall be made free of charge to
the holders and the beneficial owners of the Global Certificate and to the beneficial owners of the Definitive EuroCertificates issued in exchange, except that a person receiving Definitive Euro-Certificates must bear the cost of insurance, postage,
transportation and the like in the event that such person does not receive such Definitive Euro-Certificates in person at the offices of Clearstream Banking or Euroclear. 

(c) The delivery to the Trustee by Clearstream Banking or Euroclear of any written statement referred to above may be relied upon by the
Transferor and the Trustee as conclusive evidence that a corresponding certification or certifications has or have been delivered to Clearstream Banking or Euroclear, as applicable, pursuant to the terms of this Agreement. The Trustee, Clearstream
Banking and Euroclear, as the case may be, shall retain each certificate delivered pursuant to Section 6.11 for a period of four calendar years following the year in which such certificate is received. 

  
 58 

 (d) Upon any such exchange of all or a portion of the Global Certificate for a Definitive
Euro-Certificate or Certificates, such Global Certificate shall be endorsed by or on behalf of the Trustee to reflect the reduction of its principal amount by an amount equal to the aggregate principal amount of such Definitive Euro-Certificate or
Certificates. Until so exchanged in full, such Global Certificate shall in all respects be entitled to the same benefits under this Agreement as Definitive Euro-Certificates authenticated and delivered hereunder except that the beneficial owners of
such Global Certificate shall not be entitled to receive payments of interest on the Certificates until they have exchanged their beneficial interests in such Global Certificate for Definitive Euro-Certificates. 

SECTION 6.12 Meetings of Certificateholders. 

(a) Notice of any meeting of Investor Certificateholders, setting forth the time and place of such meeting and in general terms the action
proposed to be taken at such meeting, shall be given in accordance with Section 13.05, the first mailing and publication to be not less than 20 nor more than 180 days prior to the date fixed for the meeting. To be entitled to vote at any
meeting of Investor Certificateholders a person shall be the Holder of or a person appointed by an instrument in writing as proxy by the Holder of one or more Registered Certificates. The only persons who shall be entitled to be present or to speak
at any meeting of Investor Certificateholders shall be the persons entitled to vote at such meeting and their counsel and any representatives of the Transferor, the Master Servicer and the Trustee and their respective counsel. 

(b) At a meeting of Investor Certificateholders, persons entitled to vote Investor Certificates evidencing a majority of the Series Invested
Amount or the Class Invested Amount, as applicable, of the applicable Series or Class or the sum of the Series Invested Amounts for all applicable Series, as the case may be, shall constitute a quorum. For purposes of determining whether a quorum is
present, the applicable Class Invested Amount and Series Invested Amount shall be calculated without taking into account the Class Investor Interest represented by any Investor Certificates beneficially owned by the Transferor or any affiliate of
the Transferor. No business shall be transacted in the absence of a quorum, unless a quorum is present when the meeting is called to order. In the absence of a quorum at any such meeting, the meeting may be adjourned for a period of not less than 10
days; in the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days; at the reconvening of any meeting further adjourned for lack of a quorum, the persons entitled to
vote Investor Certificates evidencing at least 25% of the Series Invested Amount or the Class Invested Amount, as applicable, of the applicable Series or Class or the sum of the Series Invested Amounts for all applicable Series, as the case may be,
shall constitute a quorum for the taking of any action set forth in the notice of the original meeting. Notice of the reconvening of any adjourned meeting shall be given as provided above except that such notice must be given not less than five days
prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage of the Series Invested Amount or the Class Invested Amount, as applicable, or of the sum of
the Series Invested Amounts for all applicable Series, as the case may be, which shall constitute a quorum. 

  
 59 

 (c) Any Holder of a Registered Certificate who has executed an instrument in writing appointing a
person as proxy shall be deemed to be present for the purposes of determining a quorum and be deemed to have voted; provided that such Holder of a Registered Certificate shall be considered as present or voting only with respect to the
matters covered by such instrument in writing. Subject to the provisions of Section 13.01(b), any resolution passed or decision taken at any meeting of Certificateholders duly held in accordance with this Section shall be binding on all
Investor Certificateholders of the applicable Class or Series, whether or not present or represented at the meeting. 
 (d) The holding of
Registered Certificates shall be proved by the Certificate Register. The appointment of any proxy with respect to a Registered Certificate shall be proved by having the signature of the person executing the proxy guaranteed by any bank, trust
company or recognized securities dealer satisfactory to the Master Servicer. 
 (e) The Trustee shall appoint a temporary chairman of the
meeting. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of persons entitled to vote evidencing a majority of the Series Invested Amount or the Class Invested Amount, as applicable, of the applicable Series or
Class or the sum of the Series Invested Amounts for all applicable outstanding Series, as the case may be, represented at the meeting. No vote shall be cast or counted at any meeting in respect of any Investor Certificate challenged as not
outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote except as an Investor Certificateholder or proxy. Any meeting of Investor Certificateholders duly called at which a
quorum is present may be adjourned from time to time, and the meeting may be held as so adjourned without further notice. 
 (f) The vote
upon any resolution submitted to any meeting of Investor Certificateholders shall be by written ballot on which shall be subscribed the signatures of Investor Certificateholders or proxies and on which shall be inscribed the serial number or numbers
of the Investor Certificates held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Investor Certificateholders shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was published as provided above. The record shall be signed and verified by the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Master Servicer and the other to the Trustee
to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

 SECTION 6.13 Special Provisions for Certain Series. Except with respect to the
provisions of Sections 6.03, 6.04(b) and 6.06 and provisions relating specifically to the Transferor Certificate, the foregoing provisions of this Article VI may be modified with respect to any Series to the extent provided in
the applicable Series Supplement. 
 SECTION 6.14 Exchange of Investor Certificates for Transferor Interest. In the
event that the Transferor becomes a Certificate Owner or an Investor Certificateholder (in the event that Definitive Certificates are issued pursuant to Section 6.02), Discover Funding as the Holder of the Transferor Certificate may
cancel such Investor Certificates on a Distribution Date with respect to such Investor Certificates by providing notice to the Trustee of such cancellation; provided, however, that no Investor Certificates, except Class A
Certificates, may be cancelled unless Discover Funding as the Holder of the Transferor Certificate shall have been advised by the Rating Agencies that such cancellation would not cause the rating of any Class of any Series then outstanding to be
lowered below the Required Rating or withdrawn. Such cancellation shall be deemed to occur after giving effect to all allocations and payments pursuant to Article IV hereof and the applicable provisions of the Series Supplements for each
Series then outstanding as of such Distribution Date and the related Trust Distribution Date. Simultaneously with such cancellation, the Class Investor Interest of the applicable Class and the Series Investor Interest of the Series under which such
Investor Certificates were issued shall be reduced, and the Transferor Interest shall be increased, by the aggregate Class Investor Interest represented by such cancelled Investor Certificates, in each case as of the end of the related Due Period.
Such reduction in the Class Investor Interest will not result in any change in any numerator for purposes of determining any Class Percentage with respect to such Class if a Fixed Principal Allocation Event with respect to such Series has previously
occurred. Discover Funding as the Holder of the Transferor Certificate shall promptly notify the Rating Agencies of any exchange of Investor Certificates for Transferor Interest pursuant to this Section 6.14. 

ARTICLE VII.

transfer of all or substantially all of the property and assets of the Transferor, just as fully and effectually as if such successor business entity had been the original party of the first part hereto; and in the event of any such sale or transfer
the Transferor may be dissolved, wound up and liquidated at any time thereafter. 
 (b) The obligations of the Transferor hereunder
shall not be assignable, nor shall any Person succeed to the obligations of the Transferor hereunder, except in each case in accordance with the provisions of the foregoing subsection (a).

interest or penalties with respect thereto) required to be paid by the Trust or the Investor Certificateholders in connection herewith to any taxing authority, which taxes shall be the sole obligation of the Trust or the Investor Certificateholders.
Any such indemnification shall only be from assets of the Transferor, shall be subordinate to the security interest of the Trust in the Receivables and Interchange and shall not constitute a claim against the Transferor in excess of the lesser of
(i) the Transferor’s assets available to pay such claim or (ii) the amount of such claim multiplied by a fraction the numerator of which is the aggregate amount of Principal Receivables in the Trust which were originated by the

Event”) shall occur and be continuing: 
 (a) any failure by the Master Servicer to make any payment, transfer or deposit or to
give instructions to the Trustee to make any withdrawal on or before the date occurring five Business Days after the date such payment, transfer or deposit or instruction is required to be made or given as the case may be, under the terms of this
Agreement, any Series Supplement or the Master Servicing Agreement; 
 (b) failure on the part of the Master Servicer duly to observe or
perform in any respect any other covenants or material agreements of the Master Servicer set forth in this Agreement, any Series Supplement or the Master Servicing Agreement, which continues unremedied for a period of 60 days after the date on which

Interests aggregating not less than 25% of the Class Invested Amount of any Class of any Series materially adversely affected thereby; or 

(c) any representation, warranty or certification made by the Master Servicer in this Agreement, any Series Supplement, the Master Servicing
Agreement or in any certificate delivered pursuant to this Agreement, any Series Supplement or the Master Servicing Agreement shall prove to have been incorrect when made, which has a material adverse effect on the rights of the Certificateholders
of any Class of any Series and which continues to be incorrect in any material respect for a period of 60 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by
the Trustee, or to the Master Servicer and the Trustee by the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Class Invested Amount of any Class of any Series materially adversely
affected thereby; or 
 (d) the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any

authority having jurisdiction in the premises for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or the winding-up or liquidation of
its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 120 days; or the Master Servicer shall admit in writing its inability to pay its debts
generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make any assignment for the benefit of its creditors or voluntarily suspend payment of its obligations;

 then, in the event of any such Master Servicer Termination Event, so long as the Master Servicer Termination
Event shall not have been remedied, either the Trustee, or the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Class Invested Amount of any Class materially adversely affected thereby,
by notice then given in writing to the Master Servicer (and to the Trustee if given by the Investor Certificateholders) (a “Termination Notice”), may terminate all of the rights and obligations of the Master Servicer under this
Agreement and any Series Supplements then outstanding. After receipt by the Master Servicer of such Termination Notice, and on the date that a Successor Master Servicer shall have been appointed by the Trustee pursuant to Section 10.03,
all authority and power of the Master Servicer under this Agreement shall pass to and be vested in a Successor Master Servicer; and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master
Servicer, as attorney-in-fact or otherwise, all documents and other instruments upon the failure of the Master Servicer to execute or deliver such documents or instruments, and to do and accomplish all other acts or things necessary or appropriate
to effect the purposes of such transfer of servicing rights. The Master Servicer agrees to cooperate with the Trustee and such Successor Master Servicer in effecting the termination of the responsibilities and rights of the Master Servicer to
conduct servicing hereunder, including, without limitation, the transfer to such Successor Master Servicer of all authority of the Master Servicer to service the Receivables (and receivables in Charged-Off Accounts) provided for under this

Receivables (and receivables in Charged-Off Accounts) and Interchange to the Successor Master Servicer in such electronic form as the Successor Master Servicer may reasonably request and shall promptly make available to the Successor Master Servicer
all other records, correspondence and documents necessary for the continued servicing of the Receivables (and receivables in Charged-Off Accounts) and the determining and reporting of Interchange in the manner and at such times as the Successor
Master Servicer shall reasonably request. To the extent that compliance with this Section 10.01 shall require the terminated Master Servicer to disclose to the Successor Master Servicer information of any kind which the Master Servicer
reasonably deems to be confidential, the Successor Master Servicer shall be required to enter into such customary licensing and confidentiality agreements as the Master Servicer shall deem necessary to protect its interests. 

SECTION 10.02 Servicer Termination Events. If any one of the following events (a “Servicer Termination Event”) shall
occur and be continuing with respect to any Servicer:

or material agreements of such Servicer set forth in this Agreement, any Series Supplement or the Master Servicing Agreement, which continues unremedied for a period of 60 days after the date on which written notice of such failure, requiring the
same to be remedied, shall have been given to such Servicer by the Trustee, or to such Servicer and the Trustee by the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Class Invested
Amount of any Class of any Series materially adversely affected thereby; or 
 (c) any representation, warranty or certification made by any
Servicer in this Agreement, any Series Supplement, the Master Servicing Agreement or in any certificate delivered pursuant to this Agreement, any Series Supplement or the Master Servicing Agreement shall prove to have been incorrect when made, which
has a material adverse effect on the rights of the Certificateholders of any Class of any Series and which continues to be incorrect in any material respect for a period of 60 days after the date on which written notice of such failure, requiring
the same to be remedied, shall have been given to such Servicer by the Trustee, or to such Servicer and the Trustee by the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 25% of the Class Invested
Amount of any Class of any Series materially adversely affected thereby; or 
 (d) any Servicer that is not subject to the bankruptcy laws
of the United States of America shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to such Servicer or of
or relating to all or substantially all of its property, or a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator or receiver or liquidator in any insolvency,
readjustment of debt, marshalling of assets and liabilities or similar proceedings, or the winding-up or liquidation of its affairs, shall have been entered against any Servicer and such decree or order shall have remained in force undischarged or
unstayed for a period of 120 days; or any Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make any assignment for
the benefit of its creditors or voluntarily suspend payment of its obligations; or 
 (e) any Servicer that is subject to the bankruptcy
laws of the United States of America shall file a petition commencing a voluntary case under any chapter of the federal bankruptcy laws; or any such Servicer shall file a petition or answer or consent seeking reorganization, arrangement, adjustment
or composition under any other similar applicable federal law, or shall consent to the filing of any such petition, answer or consent; or any such Servicer shall appoint, or consent to the appointment of, a custodian, receiver, liquidator, trustee,
assignee, sequestrator or other similar official in bankruptcy or insolvency of it or of any substantial part of its property; or shall make an assignment for the benefit of creditors, or shall admit in writing its inability to pay its debts
generally as they become due; or 
 (f) any order for relief against any Servicer that is subject to the bankruptcy laws of the United
States of America shall have been entered by a court having jurisdiction in the premises under any chapter of the federal bankruptcy laws, and such order shall have continued undischarged or unstayed for a period of 120 days; or a decree or order by
a court having 

  
 71 

 
jurisdiction in the premises shall have been entered approving as properly filed a petition seeking reorganization, arrangement, adjustment, or composition of any such Servicer under any other
similar applicable federal law, and such decree or order shall have continued undischarged or unstayed for a period of 120 days; or a decree or order of a court having jurisdiction in the premises for the appointment of a custodian, receiver,
liquidator, trustee, assignee, sequestrator, or other similar official in bankruptcy or insolvency of any such Servicer, or of any substantial part of the property of any such Servicer, or for the winding up or liquidation of its affairs, shall have
been entered, and such decree or order shall have remained in force undischarged or unstayed for a period of 120 days; 
 then, in the event of any Servicer
Termination Event, so long as the Servicer Termination Event shall not have been remedied, either the Trustee, or the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Class Invested
Amount of any Class materially adversely affected thereby, by notice then given in writing to the Master Servicer and to the Servicer to which any such Servicer Termination Event relates (and to the Trustee if given by the Investor
Certificateholders) (a “Termination Notice”), may terminate all of the rights and obligations of such Servicer under this Agreement, any Series Supplements then outstanding and the Master Servicing Agreement. After receipt by such
Servicer of such Termination Notice, and on the date that a Successor Servicer shall have been appointed by the Trustee pursuant to Section 10.03 with respect to such Servicer, all authority and power of such Servicer under this
Agreement, any Series Supplements then outstanding and the Master Servicing Agreement shall pass to and be vested in such Successor Servicer; and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf
of such Servicer, as attorney-in-fact or otherwise, all documents and other instruments upon the failure of such Servicer to execute or deliver such documents or instruments, and to do and accomplish all other acts or things necessary or appropriate
to effect the purposes of such transfer of servicing rights. Such Servicer agrees to cooperate with the Trustee and such Successor Servicer in effecting the termination of the responsibilities and rights of such Servicer to conduct servicing
hereunder, including, without limitation, the transfer to such Successor Servicer of all authority of such Servicer to service such Servicer’s Receivables (and receivables in Charged-Off Accounts) provided for under this Agreement, including,
without limitation, all authority over all Collections which shall on the date of transfer be held by such Servicer for deposit, or which have been deposited by such Servicer in any Investor Account, or which shall thereafter be received with
respect to such Receivables (or receivables in Charged-Off Accounts), and in assisting the Successor Servicer. The terminated Servicer shall promptly make available its electronic records relating to the Receivables (and receivables in Charged-Off
Accounts) and Interchange to the Successor Servicer in such electronic form as the Successor Servicer may reasonably request and shall promptly make available to the Successor Servicer all other records, correspondence and documents necessary for
the continued servicing of the Receivables (and receivables in Charged-Off Accounts) and the determining and reporting of Interchange in the manner and at such times as the Successor Servicer shall reasonably request. To the extent that compliance
with this Section 10.02 shall require the terminated Servicer to disclose to the Successor Servicer information of any kind which such Servicer reasonably deems to be confidential, such Successor Servicer shall be required to enter into
such customary licensing and confidentiality agreements as such Servicer shall deem necessary to protect its interest. 

  
 72 

 SECTION 10.03 Trustee to Act; Appointment of Successor Master Servicer and/or Successor
Servicer. 
 (a) On and after the receipt by the Master Servicer or any Servicer of a Termination Notice pursuant to
Section 10.01 or 10.02, the Master Servicer or such Servicer, as applicable, shall continue to perform all servicing functions performed by it under this Agreement until the date specified in the Termination Notice or otherwise
specified by the Trustee in writing or, if no such date is specified in such Termination Notice, or otherwise specified by the Trustee, until a date mutually agreed upon by Master Servicer or such Servicer, as applicable, and the Trustee. The
Trustee shall as promptly as possible appoint a successor master servicer or servicer, as applicable, (the “Successor Master Servicer” or “Successor Servicer,” as applicable) and such Successor Master Servicer or
Successor Servicer shall accept its appointment by a written assumption in a form acceptable to the Trustee. In the event that a Successor Master Servicer or Successor Servicer has not been appointed or has not accepted its appointment at the time
when the Master Servicer or such Servicer, as applicable, ceases to act as such, the Trustee without further action shall automatically be appointed the Successor Master Servicer or Successor Servicer, as applicable. Notwithstanding the above, the
Trustee shall, if it is legally unable so to act, petition a court of competent jurisdiction to appoint any bank or other corporation having a net worth of not less than $100,000,000 and whose regular business includes the servicing of credit card
receivables as the Successor Master Servicer or Successor Servicer, as applicable, hereunder. The Trustee shall deliver notice to Standard & Poor’s of the proposed appointment of any Successor Master Servicer or Successor Servicer, and
any such appointment of a Successor Master Servicer shall become effective only if Standard & Poor’s shall have advised the Trustee that such appointment would not cause the rating of any Class of any Series then outstanding to be
lowered below the Required Rating or withdrawn; provided, however, that no such advice shall be necessary if such appointment is made by a court of competent jurisdiction. 

(b) Upon its appointment, the Successor Master Servicer or Successor Servicer, as applicable, shall be the successor in all respects to the
terminated Master Servicer or Servicer, as applicable, with respect to servicing functions under this Agreement and shall be subject to all the responsibilities, duties, liabilities and protections relating thereto placed on or provided to the
Master Servicer or Servicer by the terms and provisions hereof and the Successor Master Servicer or Successor Servicer, as applicable, shall be deemed to have made the representations and warranties set forth in Section 3.05 hereof, and
all references in this Agreement to the Master Servicer or such Servicer, as applicable, shall be deemed to refer to the Successor Master Servicer or Successor Servicer, as applicable, except, if agreed upon by Discover Bank and any Successor Master
Servicer or Successor Servicer, for the references in Section 11.05, which shall continue to refer to Discover Bank; provided, however, that Discover Bank shall not pay or reimburse the Trustee pursuant to
Section 11.05 for any expense, disbursement or advance of the Trustee related to or arising as a result of the negligence or bad faith of the Successor Master Servicer or Successor Servicer. Any Successor Master Servicer or Successor
Servicer, as applicable, shall expressly be authorized, subject to Section 8.06, to delegate any of its duties hereunder to Discover Bank on and after the date of any transfer of servicing pursuant to this Section 10.03. 

  
 73 

 (c) Upon its appointment, any Successor Master Servicer or Successor Servicer shall enter into
the Master Servicing Agreement, and the former Master Servicer or Servicer, as applicable, shall cease to be a party to the Master Servicing Agreement. 

(d) In connection with the appointment of a Successor Master Servicer, the Trustee may make such arrangements for the compensation of any
Successor Master Servicer out of Collections and Interchange as it and such Successor Master Servicer shall agree; provided, however, that no such compensation shall be in excess of the Monthly Servicing Fee set forth in
Section 3.03. The Holder of the Transferor Certificate agrees that if the Master Servicer or any Servicer is terminated hereunder, it will, at the request of the Trustee or any Successor Master Servicer or Successor Servicer, deposit a
portion of the Finance Charge Collections and Interchange that it is entitled to receive pursuant to Section 4.03(c)(ii) to pay its share of the compensation of such Successor Master Servicer or Successor Servicer. 

(e) All authority and power granted to any Successor Master Servicer or Successor Servicer under this Agreement shall automatically cease and
terminate upon termination of the Trust pursuant to Section 12.01, and shall pass to and be vested in the Holder of the Transferor Certificate and, without limitation, Discover Funding as the Holder of the Transferor Certificate is
hereby authorized and empowered to execute and deliver, on behalf of any Successor Master Servicer or Successor Servicer, as attorney-in-fact or otherwise, all documents and other instruments, and to do and accomplish all other acts or things
necessary or appropriate to effect the purposes of such transfer of servicing rights. Any Successor Master Servicer or Successor Servicer agrees to cooperate with the Holder of the Transferor Certificate in effecting the termination of the
responsibilities and rights of such Successor Master Servicer or Successor Servicer to conduct servicing on the Receivables (and receivables in Charged-Off Accounts). Any Successor Master Servicer or Successor Servicer shall transfer its electronic
records relating to the Receivables (and receivables in Charged-Off Accounts) to Discover Funding as the Holder of the Transferor Certificate in such electronic form as the Transferor may reasonably request and shall transfer all other records,
correspondence and documents to Discover Funding as the Holder of the Transferor Certificate in the manner and at such times as the Transferor shall reasonably request. To the extent that compliance with this Section 10.03 shall require
any Successor Master Servicer or Successor Servicer to disclose to the Transferor information of any kind which such Successor Master Servicer or Successor Servicer deems to be confidential, the Transferor shall be required to enter into such
customary licensing and confidentiality agreements as such Successor Master Servicer or Successor Servicer shall deem necessary to protect its interests. 

SECTION 10.04 Notification to Investor Certificateholders. Upon the occurrence of any Master Servicer Termination Event or any
Servicer Termination Event, the Master Servicer or Servicer, as applicable, shall give prompt written notice thereof to the Trustee and the Trustee shall give notice to the Investor Certificateholders. Upon any termination or appointment of a
Successor Master Servicer or a Successor Servicer pursuant to this Article X, the Trustee shall give prompt written notice thereof to the Rating Agencies and to the Investor Certificateholders. 

SECTION 10.05 Waiver of Past Breaches. The Holders of Investor Certificates evidencing Fractional Undivided Interests
aggregating not less than 51% of the Class Invested 

  
 74 

 
Amount of any Class of any Series affected by any default by the Master Servicer, any Servicer or the Transferor may, on behalf of all Holders of Certificates of such affected Class, waive the
effect of any Master Servicer Termination Event or Servicer Termination Event or breach by the Transferor in the performance of its obligations hereunder and its consequences, except a failure to make any required deposits or payments in accordance
with Section 4.03 or the applicable Series Supplement and except any Amortization Event arising under Sections 9.01(c), (d) or (e). Upon any such waiver of a past breach, such breach shall cease to exist with
respect to such Class of such Series, and any breach arising therefrom shall be deemed to have been remedied for every purpose of this Agreement with respect to such Class of such Series. No such waiver shall extend to any subsequent or other breach
or impair any right consequent thereon except to the extent expressly so waived. 
 ARTICLE XI. 

THE TRUSTEE 

SECTION 11.01 Duties of Trustee. 

(a) The Trustee, prior to the occurrence of any Master Servicer Termination Event or any Servicer Termination Event of which it has knowledge
and after the curing of all Master Servicer Termination Events and all Servicer Termination Events that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement or any Series
Supplement. If any Master Servicer Termination Event or any Servicer Termination Event of which the Trustee has knowledge has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by
this Agreement or any Series Supplement, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments
furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement or any Series Supplement, shall examine them to determine whether they conform to the requirements of this Agreement or such Series
Supplement. The Trustee shall give prompt written notice to the Certificateholders of any lack of conformity of any such instrument to the applicable requirements of this Agreement or any Series Supplement discovered by the Trustee that would
entitle a specified percentage of the Certificateholders of any Class of any Series to take any action pursuant to this Agreement or any Series Supplement. 

(c) Subject to Section 11.01(a) no provision of this Agreement or any Series Supplement shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or its own misconduct; provided, however, that: 

(i) The Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible
Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

  
 75 

 (ii) The Trustee shall not be personally liable with respect to any action taken,
suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Class Invested Amount of any Class of any
Series materially adversely affected thereby relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement; 

(iii) The Trustee shall not be charged with knowledge of any Master Servicer Termination Event referred to in
Section 10.01(b) or (c) or any Servicer Termination Event referred to in Section 10.02(b) or (c) or with knowledge of any Amortization Event described in Sections 9.01(b), (c),
(d), (e), (f), (i) or (j) (but only, in the case of Section 9.01(i), if such Amortization Event relates to either a Master Servicer Termination Event described in Section 10.01(b)
or (c) or a Servicer Termination Event described in Section 10.02(b) or (c)) unless a Responsible Officer of the Trustee obtains actual knowledge of such failure or the Trustee receives written notice of such failure
from the Master Servicer, any Servicer or any Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 10% of the Class Invested Amount of any Class of any Series materially adversely affected thereby; and

 (iv) The Trustee shall not be liable for any loss attributable to the investment of funds in any Permitted Investment
pursuant to this Agreement or any Series Supplement nor shall the Trustee be liable for the default or misconduct of the Master Servicer with regard to its obligations in respect of funds on deposit in any Series Principal Funding Account (as set
forth in each applicable Series Supplement). In no event shall the Trustee be liable for the payment of interest on any funds in its possession, except as expressly provided in this Agreement. 

(d) The Trustee shall not be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it, and none of the
provisions contained in this Agreement or any Series Supplement shall in any event require the Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer or any Servicer under this Agreement
or any Series Supplement except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer or any Servicer in accordance with the terms of this Agreement
or any Series Supplement. 
 (e) Except for actions expressly authorized by this Agreement or any Series Supplement, the Trustee shall take
no action reasonably likely to impair the interests of the Trust in any Receivable existing as of the Cut-Off Date or thereafter created or to impair the value of any Receivable now existing or hereafter created. 

(f) Except as provided in Section 2.10 or an applicable Series Supplement, the Trustee shall have no power to vary the corpus of
the Trust including, without limitation, the power to (i) accept any substitute obligation for a Receivable initially assigned to the Trust under 

  
 76 

 
Section 2.01 or 2.10 hereof, (ii) add any other investment, obligation or security to the Trust, or (iii) withdraw from the Trust any (a) Receivables or
(b) receivables in Charged-Off Accounts, except for a withdrawal permitted under Sections 2.05(b), 2.07(b), 2.11 (including the removal of Interchange), 3.02(b), 3.02(e), 12.01 or 12.02. 

(g) In the event that the Paying Agent or the Transfer Agent shall fail to perform any obligation, duty or agreement in the manner or on the
day required to be performed by the Paying Agent or the Transfer Agent, as the case may be, under this Agreement, the Trustee shall be obligated promptly to perform such obligation, duty or agreement in the manner so required. 

(h) If the Transferor has agreed to transfer any of its credit receivables (other than the Receivables) to another Person, upon the written
request of the Transferor, the Trustee will enter into such agreements with the transferee of such receivables as are necessary and desirable to separately identify the rights of the Trust and such other Person in the Transferor’s receivables;
provided, however, that the Trustee shall not be required to enter into any agreement which could adversely affect the interests of the Certificateholders; and provided, further, that the Transferor shall provide the
Rating Agencies with notice of any written agreement entered into pursuant to this Section 11.01(h). 
 (i) Any action, suit or
proceeding brought in respect of one or more particular Class or Series shall have no effect on the Trustee’s rights, duties and obligations hereunder with respect to any Classes or Series not the subject of such action, suit or proceeding.

 SECTION 11.02 Certain Matters Affecting the Trustee. Except as otherwise provided in Section 11.01: 

(a) The Trustee may rely on and shall be protected in acting on, or in refraining from acting in accord with, any resolution, Officer’s
Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented to
it pursuant to this Agreement by the proper party or parties; 
 (b) The Trustee may consult with counsel and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(c) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement or any Series Supplement,
or to institute, conduct or defend any litigation hereunder or in relation hereto, at the request, order or direction of any of the Certificateholders (or, for any Series that issues only collateral certificates to an entity or entities that will
issue securities supported by, among other things, such collateral certificates, to the holders of such securities, if the documents governing the terms of such securities so provide) pursuant to the provisions of this Agreement or any Series
Supplement, unless such Certificateholders (or the holders of such securities, as applicable) shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be

  
 77 

 
incurred therein or thereby; provided, however, that nothing contained herein shall relieve the Trustee of the obligations, upon the occurrence of any Master Servicer
Termination Event or any Servicer Termination Event (which has not been cured), to exercise such of the rights and powers vested in it by this Agreement or any Series Supplement, and to use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; 
 (d) The Trustee
shall not be personally liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement or any Series Supplement; 

(e) The Trustee shall not be bound to make any investigation into the facts of matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing so to do by Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51%
of the Class Invested Amount of any Class of any Series which could be materially adversely affected if the Trustee does not make such investigation; 

(f) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or
attorneys or a custodian, and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney or custodian appointed with due care by it hereunder; and 

(g) Except as may be required by Section 11.01(a) hereof, the Trustee shall not be required to make any initial or periodic
examination of any documents or records related to the Receivables or the Accounts for the purpose of establishing the presence or absence of defects, the compliance by the Transferor with its representations and warranties or for any other purpose.

 SECTION 11.03 Trustee Not Liable for Recitals in Certificates. The Trustee assumes no responsibility for the correctness of
the recitals contained herein and in the Certificates (other than the certificate of authentication on the Certificates). Except as set forth in Section 11.16, the Trustee makes no representations as to the validity or sufficiency of
this Agreement or any Series Supplement or of the Certificates (other than the certificate of authentication on the Certificates) or of any Receivable or related document. The Trustee shall not be accountable for the use or application by the
Transferor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Holder of the Transferor Certificate in respect of the Receivables or any deficiency in amounts deposited in any
Investor Accounts by the Master Servicer. 
 SECTION 11.04 Trustee May Own Investor Certificates. The Trustee in its
individual or any other capacity may become the owner or pledgee of Investor Certificates with the same rights with respect to such Investor Certificates as it would have if it were not the Trustee. 

SECTION 11.05 The Master Servicer to Pay Trustee’s Fees and Expenses. The Master Servicer covenants and agrees to pay to
the Trustee from time to time, and the Trustee 

  
 78 

 
shall be entitled to receive, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) for all services rendered
by it in the execution of the trust hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee, and the Master Servicer will pay or reimburse the Trustee (without reimbursement from any Investor
Account or otherwise) upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement or any Series Supplement (including the reasonable fees and
expenses of its agents and counsel) except any such expense, disbursement or advance as may arise from its negligence or bad faith and except as provided in the following sentence. If the Trustee is appointed Successor Master Servicer or Successor
Servicer pursuant to Section 10.03, the provision of this Section 11.05 shall not apply to expenses, disbursements and advances made or incurred by the Trustee in its capacity as Successor Master Servicer or Successor
Servicer, as applicable, and the compensation of the Trustee as Successor Master Servicer or Successor Servicer shall be determined in accordance with Section 10.03 or the relevant provisions of the Master Servicing Agreement, as
applicable. The Master Servicer’s obligations under this Section shall survive the termination of the Trust and the resignation or removal of the Trustee. 

SECTION 11.06 Master Servicer and Servicer Indemnification of Trustee. The Master Servicer and each Servicer shall indemnify and hold
harmless the Trustee for any loss, liability, expense, damage or injury (including but not limited to any judgment, award, settlement, reasonable attorneys’ fees and other costs or other expenses incurred in connection with the defense of any
actual or threatened action, proceeding or claim and any legal fees and expenses incurred in connection with any action or suit brought by the Trustee to enforce any indemnification obligation of the Master Servicer) that may be imposed on, incurred
by or asserted at any time against the Trustee (whether or not indemnified against by other parties) incurred by reason of its acceptance of the appointment hereunder. The Master Servicer and each Servicer shall also indemnify and hold harmless the
Trustee from and against any loss, liability, expense, damage or injury (including but not limited to any judgment, award, settlement, reasonable attorneys’ fees and other costs or other expenses incurred in connection with the defense of any
actual or threatened action, proceeding or claim) that may be imposed on, incurred by or asserted at any time against the Trustee (whether or not indemnified against by other parties) arising out of any acts or omissions of the Master Servicer or
such Servicer, as applicable, hereunder including, without limitation, acts or omissions of the Master Servicer or such Servicer relating to the administration of the Trust, the servicing and administration of the Receivables (and receivables in

Service or any other securities or tax authority of any jurisdiction with respect to the Receivables (and receivables in Charged-Off Accounts) or the Trust; provided, however, that neither the Master Servicer nor any Servicer shall
indemnify the Trustee to the extent any such loss, liability, expense, damage or injury results from fraud, negligence or willful misconduct by the Trustee or, except as explicitly set forth in this Agreement or any Series Supplement, from action
taken by the Trustee at the request of the Investor Certificateholders. The Master Servicer’s and each Servicer’s obligations under this Section 11.06 shall survive the termination of the Trust and the resignation or removal of
the Trustee.

times be a bank or trust company in good standing, organized and doing business under the laws of the United States of America or any state thereof authorized under such laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 and a long-term debt rating from Moody’s of at least Baa3 and from Standard & Poor’s of at least BBB- and subject to supervision or examination by federal or state banking authority. If such corporation
publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purpose of this Section 11.07, the combined capital and surplus of such

Section 11.07, the Trustee shall resign immediately in the manner and with the effect specified in Section 11.08. 

SECTION 11.08 Resignation or Removal of Trustee. 

(a) The Trustee may, upon the giving of written notice to the Transferor and the Master Servicer and the appointment of a successor trustee,
resign and be discharged from the trust hereby created. Upon receiving such notice of resignation, the Master Servicer shall promptly appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to
the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee. 
 (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 11.07 hereof and shall fail to resign after written request therefor by the Transferor, or if at any time the Trustee shall be legally unable to act, or shall be adjudged a bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Master
Servicer may remove the Trustee and promptly appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee. 

(c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this
Section 11.08 shall not become effective until acceptance of appointment by the successor trustee as provided in Section 11.09 hereof. The Master Servicer shall provide written notice to the Rating Agencies of any resignation
or removal of the Trustee and the appointment of any successor trustee. 

  
 80 

 SECTION 11.09 Successor Trustee. 

(a) Any successor trustee appointed as provided in Section 11.08 hereof shall execute, acknowledge and deliver to the Transferor
and to its predecessor Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective and such successor trustee, without any further act, deed or conveyance,
shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder and under any Series Supplement, with like effect as if originally named as Trustee herein. The predecessor Trustee shall deliver to the
successor trustee all documents and statements held by it hereunder; and the Transferor and the predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and
confirming in the successor trustee all such rights, power, duties and obligations. 
 (b) No successor trustee shall accept appointment as
provided in this Section 11.09 unless at the time of such acceptance (i) such successor trustee shall be eligible under the provisions of Section 11.07 hereof and (ii) such successor trustee shall have a long-term
debt rating of Baa3 (or a rating comparable thereto) or higher from Moody’s and of BBB- (or a rating comparable thereto) or higher from Standard & Poor’s; provided that, in the case of a bank or trust company which is the
principal subsidiary in a holding company system, the rating referred to above shall be the rating of the bank or trust company in such system. 

(c) Upon acceptance of appointment by a successor trustee as provided in this Section 11.09, such successor trustee shall notify
all Certificateholders of such succession hereunder. 
 SECTION 11.10 Merger or Consolidation of Trustee. Any Person into which the
Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be eligible under the provisions of Section 11.07 hereof, 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. The Trustee shall promptly notify Moody’s and Standard & Poor’s of the occurrence of any such event. 

SECTION 11.11 Appointment of Co-Trustee or Separate Trustee. 

(a) Notwithstanding any other provisions of this Agreement or any Series Supplement, at any time, for the purpose of meeting any legal
requirements of any jurisdiction in which any part of the Trust may at the time be located, the Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or
separate trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust, or any part thereof, and, subject to the other
provisions of this Section 11.11, such powers, duties, obligations, rights and trusts as the Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a
successor trustee under Section 11.07 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 11.09 hereof. 

  
 81 

 (b) Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and
act subject to the following provisions and conditions: 
 (i) All rights, powers, duties and obligations conferred or
imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately
without the Trustee joining in such act), except to the extent that under any applicable law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer or any
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust or any portion thereof in any such
jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee; 

(ii) No trustee hereunder shall be liable by reason of any act or omission of any other trustee hereunder; and 

(iii) The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee. 

(c) Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Section 11.11. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this
Agreement and any Series Supplement, specifically including every provision of this Agreement or any Series Supplement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be
filed with the Trustee and a copy thereof given to the Master Servicer and the Rating Agencies. 
 (d) Any separate trustee or co-trustee
may at any time constitute the Trustee as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect to this Agreement or any Series Supplement on its behalf and in its
name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law,
without the appointment of a new or successor trustee. 
 SECTION 11.12 Tax Returns. In the event the Trust shall be required
to file tax returns, the Master Servicer shall cause a firm of nationally recognized independent public accountants to prepare any tax returns required to be filed by the Trust and shall remit such returns to the Trustee for signature at least five
days before such returns are due to be filed. The  

  
 82 

 
Master Servicer shall also prepare or shall cause to be prepared all tax information required by law to be distributed to Certificateholders and shall deliver such information to the Trustee at
least five days prior to the date it is required by law to be distributed to Certificateholders. The Trustee, upon request, will furnish the Master Servicer with all such information known to the Trustee as may be reasonably required in connection
with the preparation of all tax returns of the Trust, and shall, upon request, execute such returns. In no event shall the Trustee or the Master Servicer be liable for any liabilities, costs or expenses of the Trust or the Investor
Certificateholders arising under any tax law, including, without limitation, federal, state, local or foreign income or excise taxes or any other tax imposed on or measured by income (or any interest or penalty with respect thereto or arising from a
failure to comply therewith). 
 SECTION 11.13 Trustee May Enforce Claims Without Possession of Certificates. All rights of
action and claims under this Agreement or any Series Supplement or the Certificates may be prosecuted and enforced by the Trustee without the possession of any of the Certificates or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as trustee. Any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Certificateholders in respect of which such judgment has been obtained. 
 SECTION
11.14 Suits for Enforcement. 
 (a) If a Master Servicer Termination Event or any Servicer Termination Event with respect to any
Servicer shall occur and be continuing, the Trustee, in its discretion may, subject to the provisions of Sections 10.01 and 10.02, proceed to protect and enforce its rights and the rights of the Certificateholders under this Agreement
or any Series Supplement by a suit, action or proceeding in equity or at law or otherwise, whether for the specific performance of any covenant or agreement contained in this Agreement or any Series Supplement or in aid of the execution of any power
granted in this Agreement or any Series Supplement or for the enforcement of any other, legal, equitable or other remedy as the Trustee, being advised by counsel, shall deem most effectual to protect and enforce any of the rights of the Trustee or
the Certificateholders. 
 (b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Certificateholder any plan of reorganization, arrangement, adjustment or composition affecting the Certificates or the rights of any Certificateholder thereof or to authorize the Trustee to vote in respect of the claim of any
Certificateholder in any such proceeding. 
 SECTION 11.15 Rights of Investor Certificateholders to Direct Trustee. Holders of
Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Class Invested Amount of any Class of any Series affected by the conduct of any proceeding or the exercise of any right conferred by the Trustee
shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee; provided, however, that, subject to Section 11.01, the Trustee shall have the right to decline
to follow any such direction if the Trustee, being advised by counsel, determines that the action so directed may not lawfully be taken, or if the Trustee in good faith shall, by a Responsible Officer 

  
 83 

 
or Responsible Officers of the Trustee, determine that the proceedings so directed would be illegal or involve it in personal liability or be unduly prejudicial to the rights of
Certificateholders not parties to such direction; and provided, further, that nothing in this Agreement or any Series Supplement shall impair the right of the Trustee to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by the Certificateholders. 
 SECTION 11.16 Representations and Warranties of Trustee.
The Trustee represents and warrants and any successor trustee shall represent and warrant that: 
 (a) The Trustee is organized,
existing and in good standing under the laws of the United States of America; 
 (b) The Trustee has full power, authority and right to
execute, deliver and perform this Agreement, and has taken all necessary action to authorize the execution, delivery and performance by it of this Agreement; and 

(c) This Agreement has been duly executed and delivered by the Trustee. 

SECTION 11.17 Maintenance of Office or Agency. The Holder of the Transferor Certificate will maintain at its expense in the
Borough of Manhattan, The City of New York and in Chicago, Illinois in the case of Registered Certificates an office or offices or agency or agencies where notices and demands to or upon the Trustee in respect of the Certificates, this Agreement and
any Series Supplement may be served. The Holder of the Transferor Certificate initially appoints the Corporate Trust Office of the Trustee as the office for such purposes in Chicago, Illinois and the New York office of the Trustee is located at 100
Wall Street, Suite 1600, New York, New York 10005 for such purposes in New York. The Trustee will give prompt written notice to the Master Servicer and each Servicer and to Certificateholders of any change in the location of the Certificate Register
or any such office or agency. 
 SECTION 11.18 Requests for Agreement. A copy of the Agreement or any Series Supplement
may be obtained by any Investor Certificateholder by a request in writing to the Trustee addressed to the Corporate Trust Office and will be provided at the expense of the Master Servicer. 

ARTICLE XII. 

TERMINATION 
 SECTION 12.01
Termination of the Transferor’s Obligations; Termination of Trust. 
 (a) The respective obligations and responsibilities of the
Transferor, the Master Servicer, each Servicer and the Trustee created hereby shall terminate (other than the obligation of the Trustee to make payments to Certificateholders as hereafter set forth), except with respect to the duties described in
Sections 7.04, 11.06 and Section 12.02(b), upon the Final Trust Termination Date or, if earlier, at the option of the Transferor, on the day after the Distribution Date on which funds shall have been deposited in the Series
Distribution Accounts sufficient to pay in full the Aggregate Investor Interest plus accrued and unpaid Certificate Interest at the applicable Certificate Rates on all Series then outstanding. 

  
 84 

 (b) If as of the Distribution Date with respect to each Series then outstanding in the month
immediately preceding the month in which the Final Trust Termination Date occurs the Aggregate Investor Interest would be greater than zero (after giving effect to all transfers, withdrawals and deposits to occur on such date pursuant to applicable
Series Supplements), Receivables (or interests therein), which shall be selected at random from the Receivables, in an amount sufficient to yield proceeds equal to the Aggregate Investor Interest plus any accrued and unpaid Certificate Interest with
respect to each outstanding Series and any amounts owing to any Credit Enhancement Provider with respect to any outstanding Series pursuant to the applicable Series Supplement (after giving effect to such transfers, withdrawals and deposits) shall
be sold on behalf of the Trust before the Final Trust Termination Date by an institution acceptable to the Trustee and the Master Servicer that is either (i) a nationally recognized investment bank, (ii) a nationally recognized commercial
bank or (iii) any other institution whose regular business includes the sale of receivables or trust certificates similar to the Investor Certificates, and the proceeds therefor shall be paid to the Trust on or prior to the last Distribution
Date with respect to each Series then outstanding. Neither the Transferor nor any affiliate or agent of the Transferor shall be permitted to bid for or purchase Receivables pursuant to this Section 12.01(b); provided,
however, that an affiliate or agent of the Transferor may act as selling institution for the sale as specified in the preceding sentence, so long as such affiliate or agent does not act as principal in connection with such sale. The proceeds
of such sale shall be treated as Collections on the Receivables and shall be allocated among outstanding Series and deposited in accordance with Section 4.03 and the applicable Series Supplements; provided, however, that
any such proceeds received after the end of the Due Period related to the last Distribution Date before the Final Trust Termination Date shall nevertheless be deemed to have been received during such Due Period. During such period ending on such
Distribution Date, the Master Servicer and the Servicers shall continue to process Collections on the Receivables and deposit such Collections in accordance with the provisions of Section 4.03. Section 12.03 will apply with
respect to any Receivables not sold pursuant to this Section 12.01(b). 
 SECTION 12.02 Final Distribution with Respect to
any Series. 
 (a) Written notice of the termination of any Series, specifying the Distribution Date upon which the Investor
Certificateholders of such Series may surrender their Certificates for payment of the final distribution and cancellation, shall be given (subject to at least two days’ prior notice from the Master Servicer to the Trustee) by the Trustee to
Investor Certificateholders of such Series not later than the 10th day of the month of such final distribution specifying (i) the Distribution Date (which shall be the Distribution Date upon which the deposit is made pursuant to
Section 2.05(b), 12.01(b) or 12.02(a)) upon which final payment for such Investor Certificates will be made upon presentation and surrender of such Investor Certificates at the office or offices therein designated,
(ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Investor Certificates at the office
or offices therein specified. The Master Servicer’s notice to the Trustee in accordance with the preceding sentence shall be accompanied by an Officer’s Certificate setting forth the information specified in Sections 3.07(a) and
3.07(b) covering the period from the start of the then-current fiscal year or transition 

  
 85 

 
period, as applicable, through the date of such notice. The Trustee shall give such notice to the Transfer Agent, the Paying Agent and Moody’s at the time such notice is given to such
Investor Certificateholders. 
 (b) Notwithstanding the termination of the Trust pursuant to Section 12.01(a) or the occurrence
of the Series Termination Date with respect to any Series pursuant to Section 12.02(a) and the applicable Series Supplement, all funds then on deposit in the Series Distribution Account shall continue to be held in trust for the benefit
of the Certificateholders of such Series and the Paying Agent or the Trustee shall pay such funds to such Certificateholders upon surrender of their Certificates. In the event that all of the Investor Certificateholders of such Series shall not
surrender their Certificates for cancellation within six months after the date specified in the above-mentioned written notice, the Trustee shall give a second written notice to the remaining Investor Certificateholders of such Series to surrender
their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice all the Investor Certificates of such Series shall not have been surrendered for cancellation, the Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Investor Certificateholders of such Series concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds in the
Series Distribution Account held for the benefit of such Investor Certificateholders. 
 (c) If as of the Distribution Date in the month
immediately preceding the month in which a Series Termination Date occurs, the Series Investor Interest with respect to such Series is greater than zero (after giving effect to all transfers, withdrawals and deposits to occur on such date),
Receivables (or interests therein) in an amount sufficient to yield proceeds equal to the Series Investor Interest plus any accrued and unpaid Certificate Interest with respect to such Series and any amounts owing to the Credit Enhancement Provider
with respect to such Series pursuant to the Series Supplement for such Series, if applicable, on such Series Termination Date (after giving effect to such transfers, withdrawals and deposits) shall be sold on behalf of the Trust by an institution
acceptable to the Trustee and the Master Servicer that is either (i) a nationally recognized investment bank, (ii) a nationally recognized commercial bank or (iii) any other institution whose regular business includes the sale of
receivables or of trust certificates similar to the Investor Certificates; provided, however, that in no event shall the amount of Receivables sold hereunder with respect to any Series exceed the product of (A) the aggregate
amount of Receivables in the Trust and (B) a fraction the numerator of which is the Series Investor Interest of such Series and the denominator of which is the Aggregate Investor Interest, in each case, on such Distribution Date in the month
immediately preceding the month in which such Series Termination Date occurs; and provided, further, the Receivables selected to be sold hereunder shall not be materially different from the Receivables remaining in the Trust as of such
Distribution Date and shall be selected at random from the Receivables. The proceeds (the “Series Termination Proceeds”) therefrom shall be paid to the Trust and immediately deposited into the Series Distribution Account with
respect to such Series and paid to the Investor Certificateholders of such Series and to the Credit Enhancement Provider or otherwise, if applicable, pursuant to the terms of the Series Supplement, on the Distribution Date with respect to such
Series immediately following such deposit. Such payment shall be deemed to be the final distribution with respect to such Series. Neither the Transferor nor any affiliate or agent of the Transferor shall be permitted to bid for or purchase
Receivables pursuant to this Section 12.02(c); provided, however, that an affiliate or agent may act as selling institution for the sale as specified in the first sentence of this Section 12.02(c), so long as
such affiliate or agent does not act as principal in connection with such sale. 

  
 86 

 SECTION 12.03 The Transferor’s Termination Rights. Upon the termination of the
Transferor’s obligations and responsibilities with respect to the Trust pursuant to Section 12.01 and the surrender, if applicable, of any certificated Transferor Certificate, the Trustee shall distribute to the Holder of the
Transferor Certificate any Receivables and Interchange and cash remaining in the Trust in respect of the Transferor Interest. Such distribution will be made without recourse, representation or warranty except for the warranty that since the date of
transfer by the Transferor under this Agreement, the Trustee has not sold, transferred or encumbered any such Receivables, Interchange or interests in either. Such distribution shall transfer all right, title and interest of the Trust in the
Receivables and Interchange, whether then existing or thereafter created, and all proceeds of either except, if applicable, for amounts held by the Trustee pursuant to Section 12.02(b). The Trustee shall execute and deliver such
instruments of transfer and assignment including, without limitation, any document necessary to release the Trust’s security interest in such Receivables and Interchange and to release any filing evidencing or perfecting such security interest,
in each case without recourse, as shall be reasonably requested by the Holder of the Transferor Certificate to vest in the Holder of the Transferor Certificate all right, title and interest which the Trust had in such Receivables and Interchange.

 ARTICLE XIII. 

MISCELLANEOUS PROVISIONS 

SECTION 13.01 Amendment. 

(a) This Agreement and any Series Supplement may be amended from time to time by the Master Servicer, the Transferor, the Trustee and the
Servicers, without the consent of any of the Certificateholders, for one or more of the following purposes: 
 (i) to add to
the covenants and agreements of this Agreement or any Series Supplement for the benefit of the Investor Certificateholders of all or any Classes of all or any Series (and if such covenants and agreements are for the benefit of less than all Classes
of all Series, stating that such covenants and agreements are expressly being included solely for the benefit of such Class of such Series), or to surrender any right or power herein reserved to or conferred upon the Transferor, the Master Servicer
or any Servicer; provided, however, that such action shall not adversely affect in any material respect the interests of the Holders of any Class of any Series then outstanding; and provided, further, that the permitted
activities of the Trust may be significantly changed pursuant to this Section 13.01(a) only with the consent of the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Aggregate
Invested Amount (such percentage to be calculated without taking into account the Class Invested Amount represented by any Investor Certificates beneficially owned by the Transferor or any affiliate or agent of the Transferor); 

(ii) to add provisions to or change or eliminate any of the provisions of this Agreement or any Series Supplement, provided
that any such addition, change or elimination shall not adversely affect in any material respect the interests of the Holders 

  
 87 

 
of any Class of any Series then outstanding; and provided, further, that the permitted activities of the Trust may be significantly changed pursuant to this
Section 13.01(a) only with the consent of the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Aggregate Invested Amount (such percentage to be calculated without taking into
account the Class Invested Amount represented by any Investor Certificates beneficially owned by the Transferor or any affiliate or agent of the Transferor); 

(iii) to add provisions to or change any of the provisions of this Agreement or any Series Supplement for the purpose of
accommodating the addition of Participation Interests to the Trust pursuant to Section 2.10; or 
 (iv) to cure
any ambiguity or to correct or supplement any defective or inconsistent provision contained in this Agreement, any Series Supplement or in any amendment to this Agreement or any Series Supplement. 

The Trustee is hereby authorized to join with the Transferor, the Master Servicer and the Servicers in the execution of any amendment
authorized or permitted by the terms of this Agreement, and to make any further appropriate agreements and stipulations which may be therein contained, but the Trustee shall not be obligated to enter into any such amendment which affects the
Trustee’s rights, duties or immunities under this Agreement or otherwise. A copy of each amendment adopted pursuant to this Section 13.01(a) shall be sent to the Rating Agencies. 

(b) This Agreement and any Series Supplement may also be amended from time to time by the Master Servicer, the Transferor, the Trustee and the
Servicers with the consent of the Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 66-2/3% of the Class Invested Amount of each Class adversely affected at a meeting of the Investor
Certificateholders of such Class at which a quorum is present, as described in Section 6.12, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or any Series
Supplement or of modifying in any manner the rights of the Investor Certificateholders of any Class then outstanding; provided, however, that the Trustee shall have been advised by the Rating Agencies that such amendment will not
result in the rating assigned to any Class of any Series then outstanding to be downgraded below the Required Rating or withdrawn by each Rating Agency and provided, further that no such amendment shall materially and adversely affect
the interests of the Investor Certificateholders of any Class then outstanding by reducing in any manner the amount of, or delaying the timing of, distributions which are required to be made on any Investor Certificate of any Class without the
consent of the affected Investor Certificateholders or reducing the aforesaid percentage required to consent to any such amendment, without the consent of each Investor Certificateholder of each affected Class. For purposes of calculating whether a
66- 2/3% consent has been achieved pursuant to this Section 13.01(b), the applicable Class Invested Amount or Series Invested Amount shall be calculated without taking into account the Class Invested Amount represented by any Investor
Certificates beneficially owned by the Transferor or any affiliate or agent of the Transferor, and neither the Transferor nor any affiliate or agent of the Transferor shall be entitled to vote on any amendment pursuant to this
Section 13.01(b). Notwithstanding the foregoing, the permitted activities of the Trust may be significantly changed pursuant to this Section 13.01(b) only with the consent of the Holders of Investor Certificates

  
 88 

 
evidencing Fractional Undivided Interests aggregating not less than 51% of the Aggregate Invested Amount (such percentage to be calculated without taking into account the Class Invested Amount
represented by any Investor Certificates beneficially owned by the Transferor or any affiliate or agent of the Transferor). The Trustee shall give prompt notice to the Rating Agencies of the solicitation of any consents for the purpose of amending
this Agreement or any Series Supplement pursuant to this Section 13.01(b). 
 (c) Promptly after the execution of any such
amendment or consent pursuant to Section 13.01(b), the Trustee shall notify the Investor Certificateholders of the substance of such amendment. No notice will be given to the Investor Certificateholders with regard to any amendment made
pursuant to Section 13.01(a). 
 (d) It shall not be necessary for the consent of Investor Certificateholders under this
Section 13.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Investor Certificateholders shall be subject to such reasonable requirements as the Trustee may prescribe. 
 (e)
Notwithstanding the foregoing provisions of this Section 13.01, none of (i) the execution and delivery of any Series Supplement pursuant to Section 6.06, (ii) the addition of Receivables and Interchange to the Trust
pursuant to Section 2.10, (iii) the removal from the Trust of Receivables and Interchange pursuant to Section 2.11 or of receivables in Charged-Off Accounts pursuant to Sections 3.02(b) and 3.02(e),
(iv) the addition or removal of the Transferor or Servicer in connection with an addition to or removal from the Trust of Receivables and Interchange, or (v) the replacement of any Servicer, Master Servicer or Trustee pursuant to the terms
hereof, shall constitute an amendment for purposes of this Section 13.01. 
 (f) For purposes of Sections 2.05,

security interest in the Receivables or Interchange and the proceeds of either, and shall file any such financing statements or amendments as may be necessary to continue such perfection. Each of the Transferor, the Master Servicer and each Servicer

Interchange (collectively, the “Transferred Assets.”) In the event such sale, transfer, assignment, or conveyance is deemed not to constitute a valid transfer and assignment to the Trust for the benefit of the Certificateholders of all
right, title and interest of Transferor in and to such property or is deemed to constitute a security interest, the Transferor does hereby grant to the Trust a security interest therein, and this Assignment shall constitute a security agreement
under applicable law. 
 (b) In connection with such sale, the Transferor further agrees, at its own expense, on or prior to the date of

Additional Interchange related to such Additional Accounts have been sold to the Trustee pursuant to this Assignment for the benefit of the Certificateholders. 

4. Acceptance by Trustee. Subject to the satisfaction of the conditions set forth in Section 6, the Trustee hereby acknowledges
its acceptance on behalf of the Trust of all right, title and interest previously held by the Transferor in and to the Receivables now existing and hereafter created in the Additional Accounts designated hereby and the corresponding portion of
Additional Interchange on such Additional Accounts, and declares that it shall maintain such right, title and interest, upon the trust herein set forth, for the benefit of all Certificateholders. The Trustee further acknowledges that, on or prior to
the fifth Business Day following the Addition Date, the Transferor shall deliver to the Trustee the computer file described in Section 2 of this Assignment. 

5. Representations and Warranties of Transferor. The Transferor represents and warrants that the Additional Accounts were not selected
on the basis of any selection criteria believed by the Transferor to be materially adverse to the interests of the Holders of any Class of any Series outstanding on the Effective Date or any Credit Enhancement Provider. 

6. Conditions Precedent. The acceptance of the Trustee set forth in Section 4 and the amendment of the Pooling and
Servicing Agreement set forth in Section 7 is subject to the conditions that (a) the Transferor shall have delivered to the Trustee a certificate of a Vice President or more senior officer, certifying that all requirements set forth
in Section 2.10(c) of the Pooling and Servicing Agreement for designating Additional Accounts and conveying the Principal Receivables of such Accounts and Additional Interchange, whether now existing or hereafter created, to the Trust have been
satisfied and (b) if the Servicer with respect to the Additional Accounts is not Discover Bank, such Servicer shall have entered into an amendment to, and become a party to, the Pooling and Servicing Agreement and each Series Supplement

 Exhibit A-2 

 7. Amendment of the Pooling and Servicing Agreement. The Pooling and Servicing Agreement
is hereby amended by providing that all references to the “Pooling and Servicing Agreement,” “this Agreement” and “herein” shall be deemed from and after the Addition Date to be a dual reference to the Pooling and
Servicing Agreement as supplemented by this Assignment. Except as expressly amended hereby, all of the representations, warranties, terms, covenants and conditions of the Pooling and Servicing Agreement shall remain unamended and the Pooling and
Servicing Agreement shall continue to be, and shall remain, in full force and effect in accordance with its terms and except as expressly provided herein, this Assignment of Additional Accounts shall not constitute or be deemed to constitute a
waiver of compliance with or consent to noncompliance with any term or provision of the Pooling and Servicing Agreement. 
 8. Intention
of Parties. The parties intend the sale, transfer, assignment or conveyance of Receivables and Additional Interchange in connection herewith to be a sale of financial assets in connection with a securitization, an absolute transfer for all
purposes (other than for federal, state and local income and franchise tax purposes) and to be treated as a sale for accounting purposes. 

9. Counterparts. This Assignment may be executed in any number of counterparts all of which taken together shall constitute one and the
same instrument. 
 10. Election Under Delaware Asset-Backed Securities Facilitation Act. Without limiting any other provisions of
the Pooling and Servicing Agreement, the parties hereto agree that (a) the transactions contemplated hereby constitute a “securitization transaction” and (b) to the fullest extent permitted under applicable law, including without
limitation, the Asset-Backed Securities Facilitation Act Delaware Code Ann. tit. 6, § 2703A et seq: (1) all right, title and interest to the Transferred Assets, which have been transferred to the Trust in connection with the securitization
transactions contemplated herein, shall be deemed to no longer be the property, assets or rights of the Transferor; (2) the Transferor, its creditors or, in any insolvency proceeding with respect to the Transferor or the Transferor’s
property, a bankruptcy trustee, receiver, debtor, debtor in possession or similar person, shall have no rights, legal or equitable, whatsoever to reacquire, reclaim, recover, repudiate, disaffirm, redeem or recharacterize as property of the
Transferor any of the Transferred Assets; and (3) in the event of a bankruptcy, receivership or other insolvency proceeding with respect to the Transferor or the Transferor’s property, such Transferred Assets shall not be deemed to be part
of the Transferor’s property, assets, rights or estate.

 DISCOVER CARD MASTER TRUST I 

PASS-THROUGH CERTIFICATE 
 (NOT AN INTEREST IN OR
OBLIGATION OF DISCOVER BANK OR DISCOVER FUNDING LLC AND NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY.) 

THE SECURITIES REPRESENTED BY THIS TRANSFEROR CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO THE SECURITIES ACT OF 1933 AND MAY NOT BE
TRANSFERRED OR SOLD UNLESS PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR AN OPINION OF COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED AND THE SATISFACTION OF CERTAIN OTHER REQUIREMENTS SPECIFIED IN THE AGREEMENT. 

This certifies that Discover Funding LLC, a Delaware limited liability company (“Discover Funding”), which in its capacity as the
registered holder of this Transferor Certificate is hereinafter referred to as the “Holder”, is the registered owner of a fractional undivided interest in Discover Card Master Trust I (the “Trust”), the corpus of which consists
of a portfolio of receivables (the “Receivables”) created under certain open end credit card accounts for specified Persons (the “Accounts”) originated by Discover Bank or an affiliate of Discover Bank and transferred to the
Trust, all monies due or to become due with respect thereto, all proceeds (as defined in 9-102(64) of the Uniform Commercial Code as in effect in the Applicable State) of such Receivables pursuant to a Third Amended and Restated Pooling and
Servicing Agreement, dated as December 22, 2015, as amended on or prior to the date hereof (the “Pooling and Servicing Agreement”), among U.S. Bank National Association, a national banking association organized and existing under the
laws of the United States of America, as trustee (the “Trustee”), Discover Funding LLC, as Transferor, and Discover as Master Servicer and Servicer, a summary of certain of the pertinent provisions of which is set forth herein below,
benefits under any Credit Enhancement with respect to any series of Investor Certificates issued from time to time pursuant to the Pooling and Servicing Agreement, to the extent applicable, Interchange and all other assets and interests constituting
the Trust. 
 To the extent not defined herein, the capitalized terms used herein have the meanings assigned in the Pooling and Servicing
Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Pooling and Servicing Agreement, to which Pooling and Servicing Agreement, as amended from time to time, the Holder by virtue of the acceptance
hereof assents and by which the Holder is bound. 
 This Certificate is not permitted to be transferred, assigned, exchanged or otherwise
conveyed except as expressly permitted in the Pooling and Servicing Agreement. 

  
 Exhibit D-1 

 This Certificate is the Transferor Certificate (the “Transferor Certificate”), which
represents a fractional undivided interest in the Trust including the right to receive the Collections and other amounts at the times and in the amounts specified in the Pooling and Servicing Agreement, including any series supplements thereto which
may be in effect from time to time, to be paid to the Holder of the Transferor Certificate. In addition to this Transferor Certificate, Investor Certificates, each of which will represent a Fractional Undivided Interest in the Trust, will be issued
to investors from time to time pursuant to the Pooling and Servicing Agreement and one or more series supplements thereto. The Transferor Interest on any date of determination will be an amount equal to the aggregate amount of Principal Receivables
at the end of the day immediately prior to such day of determination minus the Aggregate Investor Interest with respect to such Receivables at the end of such day. 

This Certificate does not represent an obligation of, or an interest in, Discover Bank, Discover Funding, LLC, any Additional Originator or
any Servicer. This Certificate is limited in right of payment to certain collections respecting the Receivables and Interchange, all as more specifically set forth hereinabove and in the Pooling and Servicing Agreement, including any series
supplements thereto. 
 Subject to certain conditions in the Pooling and Servicing Agreement, if the principal of all Investor Certificates
then outstanding has not been paid in full prior to the Final Trust Termination Date, the obligations created by the Pooling and Servicing Agreement and the Trust created thereby shall terminate on the Final Trust Termination Date. 

Upon the termination of the Trust pursuant to Section 12.01 of the Pooling and Servicing Agreement and the surrender of this Transferor
Certificate, the Trustee shall distribute to the Holder of this Certificate such Holder’s pro rata share of any Receivables, Interchange and cash remaining in the Trust in respect of the Transferor Interest (without recourse, representation or
warranty except for the warranty that since the date of transfer by the Transferor under the Pooling and Servicing Agreement the Trustee has not sold, transferred or encumbered any such Receivable or interest therein). Such distribution shall
transfer all right, title and interest of the Trust in the Receivables and Interchange, whether such Receivables and Interchange are then existing or thereafter created, and all proceeds of either. The Trustee shall execute and deliver such
instruments of transfer and assignment, in each case without recourse, as shall be reasonably requested by the Holder to vest in the Holder all right, title and interest which the Trustee had in the Receivables and Interchange. 

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee, by manual signature, this Certificate shall
not be entitled to any benefit under the Pooling and Servicing Agreement, or be valid for any purpose.
