 This FISCAL AND PAYING AGENCY AGREEMENT (the “Agreement”) is entered into as of
August 13, 2015 by and between Discover Bank, as Issuer (the “Bank”), and U.S. Bank National Association as Fiscal and Paying Agent (the “Fiscal and Paying Agent”). 

W I T N E S S E T H: 

WHEREAS, the Bank proposes to issue and sell $1,000,000,000 of its 2.600% Notes Due 2018 (the “Notes”) in minimum denominations of
$250,000 to certain institutional accredited investors in an offering that is exempt from registration with the Securities and Exchange Commission; and 

WHEREAS, the Bank desires to appoint the Fiscal and Paying Agent as fiscal and paying agent of the Bank with respect to the preparation,
authentication, delivery, registration and payment of the Notes; 
 NOW, THEREFORE, in consideration of the mutual promises, covenants,
conditions and agreements set forth herein, the parties hereby agree as follows: 
 ARTICLE 1 

APPOINTMENT 

Section 1.1. Appointment of Fiscal and Paying Agent. The Fiscal and Paying Agent is hereby appointed as fiscal and paying
agent for the Notes on the terms and conditions specified in this Agreement and in the Notes, and the Fiscal and Paying Agent hereby accepts such appointment. The Bank hereby appoints the Fiscal and Paying Agent as registrar for the Notes. 

ARTICLE 2 
 THE NOTES

 Section 2.1. Form of Notes. The Notes will be represented by one or more global certificates, each such
certificate hereinafter called a “Global Note.” All Global Notes shall be registered in the name of The Depository Trust Company (“DTC”), as depository, or its nominee or a successor depository or nominee. All Global Notes shall
be in substantially the form attached hereto as Exhibit A and may have such appropriate insertions, omissions, variations or substitutions as are required or permitted by, and not inconsistent with, this Agreement, and may also have such
letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with any applicable law or with any applicable rules or regulations made pursuant thereto or with the rules or regulations
of any securities exchange or governmental agency or as may, consistently herewith, be determined by the officers of the Bank executing such Global Notes, as evidenced by their execution thereof. Beneficial interests in the Global Notes will be
shown on, and transfers thereof will be effected only through, records maintained by DTC or its nominee and its participants. 







 Section 2.2. Certifications of Authorized Representatives of the Bank. 

(a) Any instruction given by the Bank to the Fiscal and Paying Agent under this Agreement shall be in the form of an Officer’s
Certificate. For the purposes of this Agreement, “Officer’s Certificate” means a certificate signed by an Authorized Representative (defined below) and delivered to the Fiscal and Paying Agent. 

(b) On or before the original issue date, the Bank shall furnish the Fiscal and Paying Agent with an Officer’s Certificate of the Bank
certifying the incumbency and specimen signatures of the representatives of the Bank who are authorized to instruct the Fiscal and Paying Agent regarding the completion and delivery of the Global Notes and take other actions hereunder (each an
“Authorized Representative”). The Bank shall notify the Fiscal and Paying Agent promptly in writing if any of such persons ceases to be so authorized or if any additional person becomes so authorized together, in the case of an additional
authorized person, with evidence satisfactory to the Fiscal and Paying Agent that such person has been so authorized and any such change shall become effective on the Business Day (as hereinafter defined) on which the Fiscal and Paying Agent
receives notice thereof. 
 Section 2.3. Authentication and Delivery. 

(a) All Notes shall be issued and delivered in accordance with the terms of this Agreement, the Global Notes and the Letter of Representations
from the Bank to DTC dated November 11, 2009. All instructions regarding the completion and delivery of Notes shall be given in writing by an Authorized Representative by telex, telecopy, electronic transmission or other means acceptable to the
Fiscal and Paying Agent. Upon receipt of such written instructions as described in the preceding sentence, the Fiscal and Paying Agent shall: 

(i) manually authenticate such Global Note or Global Notes by any one of the officers of the Fiscal and Paying Agent duly authorized and
designated by it for such purpose; and 
 (ii) deliver such Global Note or Global Notes to DTC or its nominees or retain and hold such
Global Note or Global Notes as custodian for DTC pursuant to DTC’s instructions. 
 (b) Each Note shall bear an original issue date
which shall remain the same for all Notes subsequently issued upon transfer, exchange or substitution of such original Note regardless of the date of issuance of any such subsequently issued Note. 

(c) All instructions given by the Bank pursuant to this Section 2.3 must be received by the Fiscal and Paying Agent by
11 a.m., New York City time, on the Business Day (except as indicated in Sections 3.1(b) and 6.11) preceding the original issue date for the Global Notes. For all purposes under this Agreement, the term “Business
Day” shall mean any day that is not a Saturday or Sunday and that, in The City of New York, New York, is not a day on which banking institutions are generally authorized or required by law to be closed. The Fiscal and Paying Agent shall not be
required to perform any duties on any day that is not a Business Day. 

  
 2 








 (d) The Fiscal and Paying Agent shall have no responsibility to the Bank to determine by whom a
facsimile signature of the Bank shall be affixed on the Global Notes, or whether a signature of an Authorized Representative is genuine, if such signature resembles the specimen signature of such Authorized Representative on the Officer’s
Certificate delivered pursuant to Section 2.2(b). The Fiscal and Paying Agent shall incur no liability to the Bank in acting or refraining from taking any action hereunder upon instructions contemplated hereby which the recipient thereof
believed in good faith to have been given by an Authorized Representative. In the event a discrepancy exists between the instructions as originally received by the Fiscal and Paying Agent and any subsequent instruction relating to the same subject
matter, the original instructions will be deemed controlling if action has already been taken in reliance thereon. The Fiscal and Paying Agent agrees to give notice to the Bank of such discrepancy reasonably promptly upon the discovery by the Fiscal
and Paying Agent of such discrepancy. 
 (e) Each instruction given to the Fiscal and Paying Agent in accordance with this
Section 2.3 shall constitute a representation and warranty to the Fiscal and Paying Agent by the Bank that (i) the issuance and delivery of the Global Notes to which the instruction relates have been duly and validly authorized by
the Bank, (ii) such Global Notes, when completed, authenticated and delivered pursuant hereto, will constitute valid and legally binding obligations of the Bank and (iii) the Fiscal and Paying Agent’s appointment to act for the Bank
hereunder has been duly authorized by all necessary corporate action of the Bank. 
 (f) The Bank further represents and warrants to the
Fiscal and Paying Agent that the Bank is free to enter into this Agreement and to perform the terms hereof. 
 Section 2.4.
Denominations; Issuance of Certificated Securities. 
 (a) Except as provided in paragraph (b) of this
Section 2.4, the Notes shall be issuable only in book-entry form, without coupons, in denominations of $250,000 and any amount in excess thereof which is an integral multiple of $1,000. 

(b) If at any time (i) DTC notifies the Bank in writing that it is unwilling or unable to act as depository for the Notes or if DTC
ceases to be a clearing agency registered pursuant to Section 17A of the Securities Exchange Act of 1934, as amended, and a successor depository is not appointed by the Bank within 90 days after the effective date of DTC’s ceasing to
act as depository for the Notes, (ii) the Bank, at its option, notifies the Fiscal and Paying Agent in writing that it elects to cause the issuance of Notes in definitive form or (iii) any event shall have happened and be continuing which,
after notice or lapse of time, or both, would constitute an Event of Default as defined in the Notes, the Bank will execute, and the Fiscal and Paying Agent will, upon the execution of the then standard form of the Fiscal and Paying Agent’s
agreement for certificated securities and upon receipt of instructions in writing from the Bank, authenticate and deliver Notes of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global
Notes then outstanding in exchange for such Global Notes. Any such certificated Notes will be issued in fully registered form to the persons identified by DTC as the beneficial owners thereof, without coupons, in denominations of $250,000 or any
amount in excess thereof which is an integral multiple of $1,000. Such certificated Notes may not subsequently be exchanged by a holder for Notes in denominations of less than $250,000. If Notes are issued in definitive form hereunder, payment and
other terms related to such Notes will be as set forth on the face thereof. 

  
 3 








 Section 2.5. Principal Amount; Reopening. The aggregate principal amount of
the Notes that may be authenticated and issued under this Agreement is initially limited to $1,000,000,000, except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to
Sections 2.4, 2.6 or 2.9; provided, however, that the Bank may, so long as no Event of Default (as defined in the Notes) has occurred and is continuing, reopen the Notes to issue additional Notes on the same terms and
conditions (except for issue date and offering price), with the same CUSIP number as the Notes and which shall form a single series with the originally issued Notes, without the consent of the holders of the Notes; provided, however,
that such additional Notes must be fungible with the originally issued Notes for U.S. federal income tax purposes. As used herein, the term “Notes” includes any such additional Notes. 

Section 2.6. Security Register; Registration of Transfer and Exchange. 

(a) The Fiscal and Paying Agent shall, so long as any of the Notes remain outstanding, maintain records in accordance with its customary
practices, including all forms of transfer for the Notes and shall: (i) keep at its corporate trust office or the office of its affiliate in New York City, a register (the “Security Register”) in such form as the Fiscal and Paying
Agent may determine, in which, subject to such reasonable requirements as it may prescribe, it shall provide for the registration of the Global Notes and of any exchanges or transfers thereof and (ii) maintain records showing for each
outstanding Note issued in definitive form under Section 2.4(b), the principal amount, maturity date, interest rate and other terms thereof, the date of original issue and all subsequent transfers and consolidations or exchanges. 

(b) All Notes presented for transfer shall be duly endorsed or be accompanied by a written instrument of transfer with such evidence of due
authorization and guarantee of signature as may reasonably be required by the Fiscal and Paying Agent. Upon receipt by the Bank of a Note submitted for transfer, the Bank will execute, and the Fiscal and Paying Agent will authenticate, one or more
new Notes of like tenor and terms in an aggregate principal amount equal to the principal amount of the Note presented for transfer in accordance with the transfer instructions accompanying same. The Fiscal and Paying Agent shall date its signature
on the date it signs such Notes. No service charge (other than any cost of delivery) shall be imposed by the Fiscal or Paying Agent for any exchange or registration of transfer of a Note but the Bank or Fiscal and Paying Agent may require the
payment of a sum sufficient to cover any stamp or other tax or governmental charge that may be imposed in connection therewith or presentation of evidence that such tax or charge has been paid. Notwithstanding anything to the contrary set forth
herein, no registration or transfer shall be made on or after the fifteenth day immediately preceding the Maturity Date (as defined in the Note). 

(c) Notwithstanding anything in this Agreement to the contrary, unless Notes are issued in definitive form under Section 2.4(b)
hereof, beneficial ownership of the Notes will only be shown on, and transfers thereof will be effected only through, records maintained by DTC, its nominees or its participants (as defined in the offering circular dated August 10, 2015
relating to the offering of the Notes). The Fiscal and Paying Agent shall have no responsibility 

  
 4 








 
or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests, and it shall be fully protected in acting or refraining from acting on any such information provided by DTC with respect thereto. 

Section 2.7. Persons Deemed Owners. Prior to due presentment of a Note for registration or transfer, the Bank, the Fiscal
and Paying Agent and any agent of the Bank or the Fiscal and Paying Agent may treat the person in whose name such Note is registered as the owner of such Note for the purpose of receiving payments of principal and interest, if any, and for all other
purposes whatsoever, whether or not such Note be overdue, and neither the Bank nor the Fiscal and Paying Agent shall be affected by notice to the contrary. 

Section 2.8. Cancellation of Unissued Global Notes. Promptly upon the written request of the Bank, the Fiscal and Paying
Agent shall cancel and return to the Bank all unissued Global Notes in its possession. 
 Section 2.9. Mutilated, Stolen or
Destroyed Notes. In case a Note shall at any time become mutilated, destroyed, lost or stolen and such Note or evidence satisfactory to the Bank or the Fiscal and Paying Agent of the loss, theft, or destruction thereof (together with
indemnity satisfactory to the Bank and the Fiscal and Paying Agent and such other documents of proof as may be required by them) shall be delivered to the Bank, a new Note of like tenor will be issued by the Bank in exchange for the Note so
mutilated, or in lieu of the Note so destroyed or lost or stolen. The Fiscal and Paying Agent will authenticate any such substituted Note and deliver the same on the written request or authorization of an Authorized Representative. All expenses and
reasonable charges associated with procuring the indemnity referred to above and with the preparation, authentication and delivery of a new Note shall be borne by the holder of the Note so mutilated, destroyed, lost or stolen. If any Note which has
matured or is about to mature shall become mutilated, destroyed, lost or stolen, the Bank may, instead of issuing a substitute Note, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Note) upon
compliance by the holder thereof with the provisions of this Section 2.9 (including delivery of an indemnity satisfactory to the Bank and the Fiscal and Paying Agent and such other documents of proof as may be required by them). 

Section 2.10. Redemption. 

(a) No sinking fund will be provided for the Notes. 

(b) The Notes are subject to redemption at the option of the Bank, at any time on or after October 12, 2018, in whole or in part on no
less than 10 nor more than 60 days’ prior notice delivered to the Holders. The Notes will be redeemable at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest. If fewer than all
of the Notes are to be redeemed, the Fiscal and Paying Agent will select the Notes for redemption on a pro rata basis, by lot or by such other method in accordance with the Depository’s procedures. The Notes will be redeemed in denominations of
$250,000 and integral multiples of $1,000 in excess thereof. If any Notes are to be redeemed in part only, the notice of redemption that relates to the Notes will state the portion of the Notes to be redeemed. Unless the Bank defaults in payment of
the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or the portions of the Notes called for redemption.

notice received by the Fiscal and Paying Agent not later than the applicable Regular Record Date and subject to Section 3.3 hereof. 

(c) The Fiscal and Paying Agent is authorized and, subject to its prior receipt of funds in respect thereof, will pay amounts falling due in
respect of any Note duly presented for payment as provided in paragraph (a) of this Section 3.1 as long as the Global Note representing such Note has been authenticated by one of the Fiscal and Paying Agent’s officers who was
duly designated and authorized for such purpose at the time of such authentication, notwithstanding that said officer is no longer so designated or the authority of said officer has been terminated between the time of execution and the time of
payment. 
 (d) The Fiscal and Paying Agent shall have no obligation to use its own funds for any payment of principal or interest on the
Notes or for any other purpose pursuant to this Agreement. 
 Section 3.2. Information Regarding Amounts Payable. The
Fiscal and Paying Agent shall, as soon as practicable after each record date for the payment of interest on the Notes (other than interest payable on the Maturity Date), but not later than five days preceding the related interest payment date,

 Section 3.3. Deposit
of Funds. The Bank shall deposit with the Fiscal and Paying Agent by 10 a.m., New York City time (i) on each interest payment date (other than the Maturity Date) an amount in immediately available funds sufficient to

 Section 3.4. Disposition of Funds Held for Payment of Notes. 

(a) In acting under this Agreement and in connection with the Notes, the Fiscal and Paying Agent is acting solely as agent of the Bank and
does not assume any obligation or relationship of agency or trust with the holders of the Notes or the beneficial owners of the Global Notes, except that, subject to the provisions of subsection (b) of this Section 3.4, all money
deposited with the Fiscal and Paying Agent pursuant to Section 3.3 shall be held by it on behalf of the holders of the Notes and the beneficial holders of the Global Notes entitled thereto until such money is disbursed to the holders of
the Notes (subject to escheat and other unclaimed property laws) in accordance with the provisions of the Notes and this Agreement. Money deposited with the Fiscal and Paying Agent need not be segregated from other funds of the Fiscal and Paying
Agent, except to the extent required by law. The Fiscal and Paying Agent agrees that it shall not exercise any right of set-off, lien or similar claim in respect of such money deposited with the Fiscal and
Paying Agent. 
 (b) Any money deposited with the Fiscal and Paying Agent for the payment of the principal of or interest on any Note that
remains unclaimed or unpaid for two years after such principal or interest has become due and payable or if sooner, at the effectiveness of the resignation or removal of the Fiscal and Paying Agent, shall be remitted by the Fiscal and Paying Agent
to the Bank and the holders of the Notes entitled thereto shall thereafter, as unsecured general creditors, look only to the Bank for payment thereof as successor fiscal and paying agent, and all liability of the Fiscal and Paying Agent with respect
to such money shall thereupon cease. 
 Section 3.5. Receipt and Delivery of Notices. 

(a) Forthwith upon the receipt by the Fiscal and Paying Agent of a demand or notice from any holder of a Note in accordance with the
provisions hereof, the Fiscal and Paying Agent shall promptly forward a copy thereof to the Bank. 
 (b) On behalf of and at the request and
expense of the Bank, the Fiscal and Paying Agent shall cause to be delivered to the holders of the Notes all notices required to be given by the Bank to such holders in accordance with the provisions hereof. 

Section 3.6. Additional Responsibilities. If the Bank shall ask the Fiscal and Paying Agent to perform any duties not
specifically set forth in this Agreement as duties of the Fiscal and Paying Agent (the “Additional Responsibilities”) and the Fiscal and Paying Agent chooses to perform such Additional Responsibilities, the Fiscal and Paying Agent shall be
held to the same standard of care and shall be entitled to all the protective provisions (including, but not limited to, indemnification) set forth herein with respect to such Additional Responsibilities unless the Fiscal and Paying Agent has
entered into a separate written agreement which specifically addresses the standard of care with respect to such Additional Responsibilities. 

Section 3.7. Miscellaneous. Notwithstanding anything to the contrary herein: 

(a) in paying principal and interest on the Notes hereunder, the Fiscal and Paying Agent shall be acting as a conduit and shall not be paying
such principal or interest for its own account. In the absence of written notice from the Bank to the contrary, the Fiscal and Paying Agent shall be entitled to assume that any Note presented to it, or deemed presented to it, for payment, is
entitled to be so paid; 

  
 7 








 (b) the Fiscal and Paying Agent shall not be required to invest any moneys delivered to it
pursuant to this Agreement and shall have no liability for interest on any moneys received or held by it hereunder; 
 (c) the Fiscal and
Paying Agent shall not be responsible for the accuracy of any recital of any party (other than the Fiscal and Paying Agent) that is stated herein or in the Notes or in any offering materials relating thereto and makes no representations as to the
validity or enforceability of the Notes and shall incur no responsibility in respect thereto; 
 (d) the Fiscal and Paying Agent shall be
protected in acting or refraining from acting upon any notice, order, requisition, request, consent, certificate, order, opinion (including an opinion of counsel, Officer’s Certificate or both), affidavit, letter, telegram or other paper or
document deemed by it in good faith to be genuine and correct and to have been signed or sent by the proper person or persons; and 
 (e)
any action taken by the Fiscal and Paying Agent pursuant to this Agreement upon the request or authority or consent of any person who at the time of making such request or giving such authority or consent is the holder of a Note shall be conclusive
and binding upon (i) all future holders of the same Note and any Note issued in exchange therefor or in place thereof, (ii) all beneficial owners of the same Note and (iii) all holders of the same Note issued in definitive form
pursuant to Section 2.4(b) hereof. 
 ARTICLE 4 

LIABILITY AND INDEMNIFICATION 

Section 4.1. Liability. 

(a) The duties and obligations of the Fiscal and Paying Agent are ministerial in nature and such duties and obligations shall be determined
solely by the express provisions of this Agreement. The Fiscal and Paying Agent will not have any fiduciary duties. The Fiscal and Paying Agent shall not be liable to the Bank, the holders of Notes or the beneficial owners of the Global Notes except
for the performance of such duties and obligations as are specifically set forth herein and no implied covenants shall be read into this Agreement against it. 

(b) The Fiscal and Paying Agent shall not be required to ascertain whether any action taken by the Bank hereunder, including (i) the
offering and sale of Notes, (ii) the issuance of such Notes or (iii) any amendment or termination of this Agreement, has been duly authorized by the Bank or is in compliance with any other agreement to which the Bank is a party (whether or
not the Fiscal and Paying Agent is also a party to such other agreements) or any law or governmental regulation to which the Bank is subject. The Fiscal and Paying Agent shall have no responsibility in the case of any default by the Bank in the
performance of the Notes. 
 (c) The Fiscal and Paying Agent shall not have any liability hereunder except in the case of its gross
negligence, bad faith, willful misconduct or failure to perform in accordance with this Agreement (which failure constitutes gross negligence, bad faith or willful misconduct). NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IN NO EVENT SHALL
THE FISCAL AND PAYING AGENT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES. THIS LIMITATION OF LIABILITY WILL APPLY REGARDLESS OF THE FORM OF ACTION, INCLUDING, WITHOUT LIMITATION, BREACH OF THIS CONTRACT OR TORT. 

  
 8 








 Section 4.2. Indemnification. The Bank agrees to indemnify and
hold harmless the Fiscal and Paying Agent, its officers, directors, employees and agents (each an “Indemnified Party”) from and against all losses, liabilities, obligations, claims, damages, costs and expenses of any kind or nature
whatsoever (including, without limitation, reasonable legal fees and expenses) relating to or arising out of the performance of its duties under this Agreement, except to the extent they are caused by the negligence, bad faith or willful misconduct
of such Indemnified Party or failure of such Indemnified Party to perform in accordance with this Agreement. In the event of resignation or removal of the Fiscal and Paying Agent, any successor to the performance of the obligations of the Fiscal and
Paying Agent as specified in this Agreement shall be entitled to rely upon this indemnity. These indemnification obligations shall survive the termination of this Agreement, including any termination pursuant to any applicable federal or state
bankruptcy law, to the extent enforceable under applicable law, and shall survive the resignation or removal of the Fiscal and Paying Agent while remaining applicable to any action taken or omitted by the Fiscal and Paying Agent while acting
pursuant to this Agreement. 
 Section 4.3. Agents and Advisors. The Fiscal and Paying Agent may execute any of the
powers hereunder or perform any duties hereunder either directly or by or through agents or advisors selected by it in good faith as it may reasonably require and will not be responsible for any negligence or misconduct on the part of any of them so
selected by the Fiscal and Paying Agent in good faith and without negligence. 
 ARTICLE 5 

RESIGNATION OR REMOVAL OF FISCAL AND PAYING AGENT; SUCCESSION 

Section 5.1. Resignation or Removal. The Fiscal and Paying Agent may at any time resign from its duties hereunder by giving
written notice of resignation to the Bank specifying the date on which such resignation shall become effective; provided, however, that such date shall not be less than 60 Business Days after such notice is given to the Bank. The Bank may at any
time remove the Fiscal and Paying Agent by giving written notice of removal to the Fiscal and Paying Agent specifying the date on which such removal shall be effective; provided, however, that such date shall not be less than 30 Business Days after
such notice is given to the Fiscal and Paying Agent. Any termination or resignation hereunder shall not affect the Fiscal and Paying Agent’s right to the payment of fees earned or charges incurred through the effective date of such termination
or resignation, as the case may be. 
 Section 5.2. Successor Fiscal and Paying Agent. Upon the effective date of such
resignation or removal, the Fiscal and Paying Agent shall deliver any money then held by it 

  
 9 








 
pursuant to Section 3.4(a) to the successor appointed by the Bank to serve as fiscal and paying agent for the Notes and all liability of the Fiscal and Paying Agent with respect to
such money shall thereupon cease. The Fiscal and Paying Agent shall also provide such successor with a copy of its records relating to the Notes as such successor shall reasonably request. However, the Fiscal and Paying Agent may retain copies of
any records turned over for archival purposes. If such successor has not been appointed by the effective date of such resignation or removal, the Fiscal and Paying Agent shall pay such money and deliver such records to the Bank with the same effect
as though such payment were made pursuant to Section 3.4(b); it being understood and agreed that the Bank may undertake to perform any of the functions of the Fiscal and Paying Agent. The delivery, transfer and assignment of such moneys
and records by the Fiscal and Paying Agent to its successor or the Bank, as the case may be, shall be sufficient, without the requirement of any additional act or the requirement of any indemnity to be given by the Fiscal and Paying Agent, to
relieve the Fiscal and Paying Agent of all further responsibility for the exercise of the rights or the performance of the obligations vested in the Fiscal and Paying Agent pursuant to this Agreement. The Bank shall notify, or cause the Fiscal and
Paying Agent to notify, each holder of Global Notes of the appointment of any successor Fiscal and Paying Agent or the undertaking of the Bank to perform the functions of the Fiscal and Paying Agent. 

Section 5.3. Successor by Merger, Etc. Any corporation or association into which the Fiscal and Paying Agent may be
converted or merged, or with which it may be consolidated, or to which it may sell or transfer its corporate trust and agency business as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation or
transfer to which it is a party, shall be and become successor Fiscal and Paying Agent hereunder and shall be invested with all of the rights, powers, trusts, duties and obligations of the Fiscal and Paying Agent hereunder, without the execution or
filing of any instrument or any further act. The Fiscal and Paying Agent shall provide notice to the Bank of any such conversion, merger, consolidation, sale or transfer as soon as practicable after the Fiscal and Paying Agent obtains knowledge that
such event will occur or has occurred.

of the Depository to another nominee of the Depository or to the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository unless and until this Security is exchanged in whole or in part
for Securities in definitive form. Unless this certificate is presented by an authorized representative of the Depository to the Corporate Trust Department of U.S. Bank National Association, as Fiscal and Paying Agent or any duly appointed successor
Fiscal and Paying Agent (the “Fiscal and Paying Agent”), and any certificate issued is registered in the name of Cede & Co. or such other name as is requested in writing by an authorized representative of the Depository (and any

 If the Maturity Date or any other
Interest Payment Date falls on a day that is not a Business Day (as defined below), the related payment shall be made on the next succeeding Business Day with the same force and effect as if made on the day such payment was due, and no interest
shall accrue on the amount so payable for the period from and after such Maturity Date or Interest Payment Date, as the case may be. The term “Business Day” means any day that is not a Saturday or Sunday and that is not a day on which
banking institutions are generally authorized or required to be closed in The City of New York, New York.

 Form of Reverse Side of Note 

1. This Security is one of a duly authorized issue of securities of the Bank, designated as its “2.600% Notes Due 2018” (the
“Securities”), initially limited in aggregate principal to $1,000,000,000. The Bank may, so long as no Event of Default (as defined below) has occurred and is continuing and without the consent of the Holders (as defined below) hereof,
issue additional Securities and thereby increase such aggregate principal amount in the future, on the same terms and conditions (except for issue date and offering price) and with the same CUSIP number as this Security; provided, however,
that such additional Securities shall be consolidated and form a single series with this Security only if such additional Securities are fungible with this Security for U.S. federal income tax purposes. The Bank, for the benefit of the registered
holders from time to time of the Securities (collectively, the “Holders”), has entered into a Fiscal and Paying Agency Agreement, dated as of August 13, 2015 (as the same may be amended, supplemented or otherwise modified from time to
time, the “Fiscal and Paying Agency Agreement”), between the Bank and the Fiscal and Paying Agent. Reference is hereby made to the Fiscal and Paying Agency Agreement (copies of which are on file and available for inspection during normal
business hours at the offices of the Fiscal and Paying Agent at U.S. Bank National Association, 100 Wall Street – Suite 1600, New York, NY 10005, Attention: Corporate Trust Administration, or at such other place or places as the Fiscal and
Paying Agent shall designate by notice to the Holder in whose name this Security is registered on the Security Register (as defined in Section 3 of this Security)), for a statement of the further rights of the Holders and the further rights,
limitations of rights, duties and indemnities thereunder of the Bank and the Fiscal and Paying Agent and of the terms upon which the Securities are, and are to be, authenticated and delivered. 

Payment of the principal and interest payable on the Maturity Date will be made by wire transfer in immediately available funds to a bank
account in the United States designated by the Holder, upon presentation and surrender of this Security at the office of the Fiscal and Paying Agent or its affiliate in New York City or at such other place or places as the Fiscal and Paying Agent
shall designate by notice to the Holder, provided that this Security is presented to the Fiscal and Paying Agent in time for the Fiscal and Paying Agent to make such payments in such funds in accordance with its normal procedures and subject to the
deposit by the Bank of sufficient funds to enable the Fiscal and Paying Agent to make such payments. Payments of interest (other than interest payable on the Maturity Date) shall be made by wire transfer in immediately available funds to a bank
account in the United States designated by the Holder in a written notice received by the Fiscal and Paying Agent not later than the applicable Record Date (as defined below). Interest payable on any Interest Payment Date (other than the Maturity
Date) shall be payable to the Holder in whose name this Security is registered at the close of business on the May 1 or November 1, as the case may be (whether or not a Business Day), immediately preceding the Interest Payment Date (each
such date being referred to herein as a “Regular Record Date”), notwithstanding the cancellation of this Security after such Regular Record Date and prior to or on such Interest Payment Date. Any interest so payable, but not punctually
paid or made available for payment, on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date and such defaulted interest will be paid to the Person in whose name this Security is registered at the
close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Bank (a “Special Record Date”), notice of which shall be given to the Holder of this Security not less than 10 days prior to such
Special 

  
 A-4 








 
Record Date (the Regular Record Date and Special Record Date are referred to herein collectively as “Record Dates”). Interest payable on this Security on the Maturity Date will be
payable to the Holder to whom the principal of this Note is payable on such date. To the extent permitted by applicable law, interest shall accrue, at the rate at which interest accrues on the principal of this Security, on any amount of principal
of or interest on this Security not paid when due. All payments on this Security shall be applied first to accrued interest and the balance, if any, to principal. 

2. Payments of principal of and interest on this Security shall be made in such coin or currency of the United States of America as at the
time of payment shall be legal tender for the payment of public and private debts. Until the date on which all of the Securities shall have been surrendered or delivered to the Fiscal and Paying Agent for cancellation or destruction, or become due
and payable and a sum sufficient to pay the principal of and interest on all of the Securities shall have been made available for payment and either paid or returned to the Bank as provided herein and in the Fiscal and Paying Agency Agreement, the
Fiscal and Paying Agent or its affiliate shall at all times maintain an office or agency in New York City, where Securities may be presented or surrendered for payment; provided that, any successor Fiscal and Paying Agent appointed by the Bank as
permitted by Section 10 of this Security, or the Bank upon undertaking the performance of the functions of Fiscal and Paying Agent, shall not be required to maintain an office in New York City but shall be required to maintain an office or
agency the location of which shall be communicated promptly to the Holder of this Security. 
 3. Except as otherwise provided on the face
of this Security, this Security is transferable in whole or in part, and may be exchanged for a like aggregate principal amount of Securities of other authorized denominations, by the Holder in person, or by his, her or its attorney duly authorized
in writing, at the office of the Fiscal and Paying Agent or its affiliate in New York City. The Fiscal and Paying Agent shall maintain a register providing for the registration of the Securities and any exchange or transfer thereof (the
“Security Register”). Upon surrender or presentation of this Security for exchange or registration of transfer, the Bank shall execute and the Fiscal and Paying Agent shall authenticate and deliver in exchange therefor a Security or
Securities, each in a denomination of $250,000 or any amount in excess thereof which is an integral multiple of $1,000 which has or have an aggregate denomination equal to the denomination of this Security and is or are registered in such name or
names requested by the Holder. Any Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Fiscal and Paying Agent) be duly endorsed, or accompanied by a written instrument of transfer with such
evidence of due authorization and guarantee of signature as may reasonably be required by the Fiscal and Paying Agent in form satisfactory to the Fiscal and Paying Agent, duly executed by the Holder or his, her or its attorney duly authorized in
writing, and with such tax identification number or other information for each person in whose name a Security is to be issued as the Fiscal and Paying Agent may reasonably request to comply with applicable law. No exchange or registration of
transfer of this Security shall be made on or after the fifteenth day immediately preceding the Maturity Date. 
 No service charge (other
than any cost of delivery) shall be imposed for any exchange or registration of transfer of this Security, but the Bank or Fiscal and Paying Agent may require the payment of a sum sufficient to cover any stamp or other tax or governmental charge
that may be imposed in connection therewith (or presentation of evidence that such tax or charge has been paid). 

  
 A-5 








 Prior to due presentment of this Security for registration of transfer, the Bank, the Fiscal and
Paying Agent and their respective agents may treat the Holder in whose name this Security is registered in the Security Register as the absolute owner of this Security for the purpose of receiving payments of principal of and interest on this
Security and for all other purposes whatsoever, whether or not this Security be overdue, and the Bank and the Fiscal and Paying Agent shall not be affected by any notice to the contrary. 

4. This Security is not subject to repayment at the option of the Holder prior to the Maturity Date and is not subject to any sinking fund.

 5. This Security is subject to redemption at the option of the Bank, at any time on or after October 12, 2018, in whole or in part
on no less than 10 nor more than 60 days’ prior notice delivered to the Holders. This Security will be redeemable at a redemption price equal to 100% of the principal amount of this Security to be redeemed, plus accrued and unpaid interest. If
fewer than all of the Securities are to be redeemed, the Fiscal and Paying Agent will select the Securities for redemption on a pro rata basis, by lot or by such other method in accordance with the Depository’s procedures. This Security will be
redeemed in denominations of $250,000 and integral multiples of $1,000 in excess thereof. If any Securities are to be redeemed in part only, the notice of redemption that relates to such Securities will state the portion of such Securities to be
redeemed. Unless the Bank defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on such Securities or the portions of such Securities called for redemption. 

6. The indebtedness of the Bank evidenced by this Security, including the principal and interest, is unsecured and unsubordinated but it is
subordinate and junior in right of payment to the Bank’s obligations to its depositors and other obligations that are entitled to any priorities or preferences, such as its obligations under bankers’ acceptances and letters of credit and
its obligations to any Federal Reserve Bank or the Federal Deposit Insurance Corporation (“FDIC”) and to any rights acquired by the FDIC as a result of loans made by the FDIC to the Bank or the purchase or guarantee of any of its assets by
the FDIC pursuant to the provisions of 12 U.S.C. Section 1823(c), (d) or (e), in each case whether outstanding at the date of this Security or hereafter incurred (except any such obligations which rank on a parity with or junior to
this Security). In the case of any insolvency proceedings, receivership, conservatorship, reorganization, readjustment of debt, marshalling of assets and liabilities or similar proceedings or any liquidation, dissolution or winding-up of the Bank, whether voluntary or involuntary, all such obligations, except obligations that expressly rank on a parity with or junior to this Security, shall be entitled to be paid in full before any
payment shall be made on account of the principal of, or interest on, this Security. In the event of any such proceeding, after payment in full of all sums owing with respect to such prior obligations, the Holder of this Security, together with the
holders of any other obligations of the Bank ranking on a parity with this Security, shall be entitled to be paid from the remaining assets of the Bank, the unpaid principal of, and the unpaid interest on, this Security or such other obligations
before any payment or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any obligations of the Bank ranking junior to this Security. Nothing herein shall impair the obligation of the Bank,
which is absolute and unconditional, to pay the principal of and any interest on this Security in accordance with its terms. 

  
 A-6 








 7. Notwithstanding any other provisions of this Security, including specifically those set forth
in the sections relating to events of default and covenants of the Bank, it is expressly understood and agreed that the FDIC or any other receiver or conservator of the Bank shall have the right in the performance of his or her legal duties, and as
part of any transaction or plan of reorganization or liquidation designed to protect or further the continued existence of the Bank or the rights of any parties or agencies with an interest in, or claim against, the Bank or its assets, to transfer
or direct the transfer of the obligations of this Security to any national banking association, state bank or bank holding company selected by him or her which shall expressly assume the obligation of the due and punctual payment of the unpaid
principal and interest on this Security and the due and punctual performance of all covenants and conditions hereof; and that the completion of such transfer and assumption shall serve to supersede and void any default, acceleration or subordination
which may have occurred, or which may occur due or related to such transaction, plan, transfer or assumption, pursuant to the provisions of this Security, and shall serve to return the Holder to the same position, other than for substitution of the
obligor, it would have occupied had no default, acceleration or subordination occurred; except that any interest and principal previously due, other than by reason of acceleration, and not paid shall, in the absence of a contrary agreement by the
Holder of this Security, be deemed to be immediately due and payable as of the date of such transfer and assumption, together with the interest from its original due date at the rate provided for herein. 

8. Any depository institution, as that term is defined in Section 3(c)(1) of the Federal Deposit Insurance Act, which holds this Security
