 SECTION 11. Credit Enhancement. 
 (a)
Initial Credit Enhancement. The Master Servicer hereby represents with respect to the Initial Credit Enhancement and shall be deemed to represent with respect to any successor Credit Enhancement that (i) the Master Servicer has provided
for the Credit Enhancement for the account of the Trustee and for the benefit of the Investor Certificateholders, (ii) the Master Servicer has entered into a Credit Enhancement Agreement, (iii) the Credit Enhancement permits the Trustee or
the Master Servicer, acting as the Trustee’s attorney-in-fact or otherwise, to make Credit Enhancement Drawings from time to time in an amount up to the Total Available Credit Enhancement Amount at such time, for the purposes set forth in this
Agreement and (iv) the Credit Enhancement and the respective Credit Enhancement Agreement may be terminated by the Trustee without penalty if (x) the Master Servicer 

  

 51 

 
elects to obtain a successor Credit Enhancement and such successor Credit Enhancement does not cause the ratings of the Investor Certificates of the Series
established hereby to be withdrawn or lowered by either of the Rating Agencies from the respective ratings of such Investor Certificates immediately prior to such election or (y) if the Credit Enhancement is not Funded Credit Enhancement, the
Credit Enhancement Provider ceases to be a Qualified Credit Enhancement Provider. 
 (b) Successor Credit Enhancement. 
 (i) If the Credit Enhancement is not Funded Credit Enhancement and if, at any time, the provider of such Credit Enhancement ceases to be a
Qualified Credit Enhancement Provider, the Master Servicer shall obtain a successor Credit Enhancement within 30 days or such longer period as will not result in the lowering or withdrawal of the rating of any Class of any Series then outstanding by
the Rating Agencies (a) which, if such successor Credit Enhancement is not to be Funded Credit Enhancement, will be issued by a Qualified Credit Enhancement Provider and (b) with respect to which the representations set forth in
Section 11(a) will be satisfied; provided, however, that the Master Servicer shall not be required to continue efforts to obtain a successor Credit Enhancement if the then existing Credit Enhancement Provider again becomes a
Qualified Credit Enhancement Provider and remains such; and, provided, further, that unless otherwise agreed to by the Rating Agencies, the Credit Enhancement and Credit Enhancement Agreement will not be terminated and no successor
Credit Enhancement Provider shall be selected if the successor Credit Enhancement, the successor Credit Enhancement Agreement, or the selection of such successor Credit Enhancement Provider would cause the ratings of the Investor Certificates of the
Series established hereby to be withdrawn or lowered by either Rating Agency from the respective ratings of such Investor Certificates immediately prior to such selection. The Master Servicer, the Trustee and the Sellers shall promptly enter into
any such successor Credit Enhancement Agreement, and the Master Servicer shall use its best efforts to secure the signature of any other required party to such agreement. 
 (ii) Regardless of whether the Credit Enhancement is Funded Credit Enhancement, the Master Servicer may elect, at any time, to obtain a
successor Credit Enhancement, provided that such successor Credit Enhancement does not cause the ratings of the Investor Certificates of the Series established hereby to be withdrawn or lowered by either of the Rating Agencies from the respective
ratings of such Investor Certificates immediately prior to such election. 
 (iii) In any case, subject to the foregoing, any
successor Credit Enhancement obtained by the Master Servicer need not consist of the same type of Credit Enhancement as the Initial Credit Enhancement, but may consist of a different type of facility, including, but not limited to, a reserve
account, a cash collateral account, an irrevocable standby letter of credit, a surety bond or a combination of any of the above. Upon issuance of, or other provision for, any such successor Credit Enhancement, the Trustee shall terminate the prior
Credit Enhancement and Credit Enhancement Agreement. 
  

 52 

 (c) Supplemental Credit Enhancement Event. Upon the occurrence of a Supplemental Credit
Enhancement Event, Discover Bank as Servicer shall, within 60 days of notice from Standard & Poor’s of the withdrawal or downgrade (or such longer period as may be agreed to by Standard & Poor’s), arrange for the payment
of the Supplemental Credit Enhancement Amount, if any, by a Person other than Discover Bank (or from Series Excess Servicing) to the Trustee as administrator of the Credit Enhancement for application in accordance with the provisions of the Credit
Enhancement Agreement. Both the form and the provider of the Supplemental Credit Enhancement Amount, if any, shall be determined at the time it is to be paid; provided, that the Master Servicer shall have received confirmation from
Standard & Poor’s that the arrangements with respect to the Supplemental Credit Enhancement Amount, if any, will not result in the rating of the Investor Certificates of the Series established hereby being withdrawn or lowered. In
addition to the foregoing, the Master Servicer shall notify Moody’s of the occurrence of a Supplemental Credit Enhancement Event as soon as practicable after such occurrence, and shall notify Moody’s in advance of its implementation of the
form and provider of the Supplemental Credit Enhancement Amount, if any. 
 SECTION 12. Alternative Credit Support Election.

 (a) The Sellers may elect to effect a change in the calculation of the Class Percentage with respect to Finance Charge Collections during
the Amortization Period, as set forth in the definition of “Class Percentage,” and increase the Available Class B Credit Enhancement Amount, by making an Alternative Credit Support Election. An Alternative Credit Support Election may be
made as follows: 
 (i) at any time during the Revolving Period, Discover Bank on behalf of the Holder of the Seller
Certificate shall deliver written notice of such Alternative Credit Support Election to the Rating Agencies, the Trustee and the Credit Enhancement Provider; 
 (ii) prior to the last day of the Revolving Period, the Additional Credit Support Amount shall be paid to the Trustee as administrator of
the Credit Enhancement for application in accordance with the provisions of the Credit Enhancement Agreement; provided, however, that following an Amortization Event, the Additional Credit Support Amount may be paid to the Trustee as
administrator of the Credit Enhancement at any time on or prior to the last day of the Due Period in which the Amortization Event occurs; 
 (iii) prior to the last day of the Revolving Period (or, following an Amortization Event during the Revolving Period, on or prior to the last day of the Due Period in which the Amortization Event occurs), the Rating
Agencies shall have confirmed that the Alternative Credit Support Election shall not cause a reduction in or withdrawal of the rating of any Class of Investor Certificates of the Series established hereby; and 
 (iv) prior to the last day of the Revolving Period (or, following an Amortization Event during the Revolving Period, on or prior to the
last day of the Due Period in which the Amortization Event occurs), Discover Bank on behalf of the Holder of the Seller Certificate shall have delivered to the Rating Agencies written confirmation that the conclusions reached in the legal opinions
delivered on the Initial Closing Date regarding the absolute transfer of the Receivables and the security interest of the Trust in the Receivables are not affected by the Alternative Credit Support Election. 
  

 53 

 (b) If each of the actions set forth in Section 12(a) above has been taken or satisfied as required,
the Alternative Credit Support Election shall become effective on the last day of the Due Period in which the Additional Credit Support Amount has been paid to the Trustee as administrator of the Credit Enhancement (an “Effective Alternative
Credit Support Election”). 
 (c) At any time until the Alternative Credit Support Election becomes effective, such Alternative Credit
Support Election may be cancelled upon notice to the Rating Agencies, the Trustee and the Credit Enhancement Provider. Thereafter, the Additional Credit Support Amount, if any, shall be returned by the Trustee as administrator of the Credit
Enhancement in accordance with the Credit Enhancement Agreement. 
 SECTION 13. Calculation of Investor Losses. 
 (a) For each Distribution Date, the Master Servicer shall calculate the Class Investor Charged-Off Amount and the Class Cumulative Investor Charged-Off
Amount with respect to each Class, in each case as of the end of the related Due Period. 
 (b) If on any Distribution Date, the Class
Investor Charged-Off Amount with respect to any Class exceeds the Class Charge-Off Reimbursement Amount with respect to such Class, the Class Investor Interest and the Class Invested Amount for such Class shall each be reduced by the amount of such
excess (an “Investor Loss” with respect to such Class). 
 (c) On each Distribution Date the Class Investor Interest and the Class
Invested Amount for each Class shall be increased by, and the amount of aggregate unreimbursed Investor Losses for each such Class shall be decreased by, the positive difference, if any, between the Class Charge-Off Reimbursement Amount on such
Distribution Date and the Class Investor Charged-Off Amount for such Distribution Date; provided, however, that neither the Class Invested Amount nor the Class Investor Interest shall exceed the Class Initial Investor Interest for such
Class minus the sum of (x) the aggregate amount of payments of Certificate Principal paid to the Investor Certificateholders of such Class prior to such Distribution Date, (y) in the case of the Class Investor Interest, the amount
on deposit in the Series Principal Funding Account for the benefit of such Class in respect of Collections of Principal Receivables and (z) the aggregate amount of losses, if any, on investments of principal of funds on deposit in the Series
Principal Funding Account for the benefit of such Class; and provided, further, that the amount of Investor Losses with respect to any Class shall not be reduced to an amount less than zero. 
 SECTION 14. Servicing Compensation. As compensation for its servicing activities hereunder and under the Pooling and Servicing Agreement and
reimbursement of its expenses as set forth in Section 3.03 of the Pooling and Servicing Agreement, the Master Servicer shall be entitled to receive the Class Monthly Servicing Fees with respect to the Series established hereby in respect of any
Due Period (or portion thereof) prior to the earlier of the date on which the Series Investor Interest is reduced to zero and the Series Termination Date. The Class Monthly Servicing Fees shall be paid to the Master Servicer on behalf of each Class
on each Distribution Date pursuant to Section 10. 
  

 54 

 SECTION 15. Class Interest Rate Caps. 
 (a) In the event that the Master Servicer has obtained a Class Interest Rate Cap in favor of the Trustee for the benefit of a Class or Subclass that does
not have a fixed or maximum Certificate Rate, the Master Servicer hereby represents that such Class Interest Rate Cap provides that (i) the Trust shall not be required to make any payments thereunder and (ii) the Trust shall be entitled to
receive payments (determined in accordance with the Class Interest Rate Cap) from the Interest Rate Cap Provider on an Interest Payment Date if LIBOR or the Commercial Paper Rate, as applicable, for the related Calculation Period exceeds the Class
Cap Rate for the applicable Class or Subclass. Any Class Interest Rate Cap Payment shall be deposited into the Series Interest Funding Account. 
 (b) In the event that the commercial paper or certificate of deposit rating of the Interest Rate Cap Provider is withdrawn or reduced below the ratings specified in the Series Term Sheet (or, in either case, such lower rating as the
applicable Rating Agency shall allow), then within 30 days after receiving notice of such decline in the creditworthiness of the Interest Rate Cap Provider as determined by either Rating Agency, either (x) the Interest Rate Cap Provider, with
the prior confirmation of the Rating Agencies that such arrangement will not result in the reduction or withdrawal of the rating of any Investor Certificates of the Series established hereby, will enter into an arrangement the purpose of which shall
be to assure performance by the Interest Rate Cap Provider of its obligations under the Class Interest Rate Caps; or (y) the Master Servicer shall at its option either (i) with the prior confirmation of the Rating Agencies that such action
will not result in a reduction or withdrawal of the rating of any Investor Certificates of the Series established hereby, cause the Interest Rate Cap Provider to pledge securities in the manner provided by applicable law, which shall be held by the
Trustee or its agent free and clear of the Lien of any third party, in a manner conferring on the Trustee a perfected first Lien in such securities securing the Interest Rate Cap Provider’s performance of its obligations under the Class
Interest Rate Caps, or (ii) provided that Replacement Class Interest Rate Caps or Qualified Substitute Cap Arrangements meeting the requirements of Section 15(c) have been obtained, direct the Trustee (A) to provide written notice to
the Interest Rate Cap Provider of its intention to terminate the Class Interest Rate Caps within such 30-day period and (B) to terminate the Class Interest Rate Caps within such 30-day period, to request the payment to it of all amounts due to
the Trust under the Class Interest Rate Caps through the termination date and to deposit any such amounts so received, on the day of receipt, to the Series Interest Funding Account, or (iii) establish any other arrangement (including an
arrangement or arrangements in addition to or in substitution for any prior arrangement made in accordance with the provisions of this Section 15(b)) satisfactory to the Rating Agencies such that the Rating Agencies will not reduce or withdraw
the rating of any Investor Certificates of the Series established hereby (a “Qualified Substitute Cap Arrangement”); provided, however, that in the event at any time any alternative arrangement established pursuant to clause
(x) or (y)(i) or (y)(iii) above shall cease to be satisfactory to the Rating Agencies then the provisions of this Section 15(b) shall again be applied and in connection therewith the 30-day period referred to above shall commence on the
date the Master Servicer receives notice of such cessation. 
  

 55 

 (c) Unless an alternative arrangement pursuant to clause (x) or (y)(i) of Section 15(b) is
being established, the Master Servicer shall use its best efforts to obtain Replacement Class Interest Rate Caps or Qualified Substitute Cap Arrangements meeting the requirements of this Section 15(c) during the 30-day period referred to in
Section 15(b). The Trustee shall not terminate the Class Interest Rate Caps unless, prior to the expiration of the 30-day period referred to in Section 15(b), the Master Servicer delivers to the Trustee (i) Replacement Class Interest
Rate Caps or Qualified Substitute Cap Arrangements, (ii) to the extent applicable, an Opinion of Counsel as to the due authorization, execution and delivery and validity and enforceability of each such Replacement Class Interest Rate Cap or
Qualified Substitute Cap Arrangement, as the case may be, and (iii) confirmation from each Rating Agency that the termination of the Class Interest Rate Caps and their replacement with such Replacement Class Interest Rate Caps or Qualified
Substitute Cap Arrangements will not adversely affect its rating of the Investor Certificates of the Series established hereby. 
 (d) The
Master Servicer shall notify the Trustee, the Rating Agencies and the Credit Enhancement Provider within five Business Days after obtaining knowledge that the commercial paper or certificate of deposit rating of the Interest Rate Cap Provider has
been withdrawn or reduced by either Rating Agency. 
 (e) Notwithstanding the foregoing, the Master Servicer may at any time obtain
Replacement Class Interest Rate Caps, provided that the Master Servicer delivers to the Trustee (i) an Opinion of Counsel as to the due authorization, execution and delivery and validity and enforceability of such Replacement Class Interest
Rate Caps and (ii) confirmation from the Rating Agencies that the termination of the then current Class Interest Rate Caps and their replacement with such Replacement Class Interest Rate Caps will not adversely affect the rating of the Investor
Certificates of the Series established hereby. 
 (f) The Trustee hereby appoints the Master Servicer to perform the duties of the
calculation agent under the Class Interest Rate Caps and the Master Servicer accepts such appointment. 
 SECTION 16. Investor
Certificateholders’ Monthly Statement. On each Distribution Date, the Paying Agent shall forward to each Certificateholder of the Series established hereby a statement substantially in the form of Exhibit B prepared by the Trustee (based on
information provided by the Master Servicer) setting forth the information listed thereon. 
 SECTION 17. Master Servicer’s Monthly
Certificate. On or before the second Business Day preceding each Distribution Date, the Master Servicer shall forward to Discover Bank on behalf of the Holder of the Seller Certificate, the Trustee and the Paying Agent a certificate of a
Servicing Officer substantially in the form of Exhibit C setting forth the information listed thereon. 
 SECTION 18. Additional
Amortization Events. If any one of the following events shall occur: 
 (a) on any Distribution Date, the three month rolling average
Series Excess Spread is less than the Series Buffer Amount, the three month rolling average Group Excess Spread is less than the Group Buffer Amount and for so long as any Series that is not an Interchange Series is outstanding, the three month
rolling average Interchange Subgroup Excess Spread is less than the Interchange Subgroup Buffer Amount; 
  

 56 

 (b) if the Series established hereby has an Accumulation Period and, after giving effect to payments and
distributions on the Class Expected Final Payment Date or the Class Final Maturity Date, as applicable, with respect to any Class, the Class Invested Amount for such Class is not reduced to zero; 
 (c) if applicable, following either (i) the withdrawal or reduction of the commercial paper or certificate of deposit rating of any Interest Rate
Cap Provider to below the ratings specified in the Series Term Sheet (or, in either case, such lower rating as the applicable Rating Agency has allowed) or (ii) notice from either Rating Agency that any Qualified Substitute Cap Arrangement or
any other arrangement established pursuant to Section 15 is no longer satisfactory to such Rating Agency, the Master Servicer shall fail, within the applicable time period specified in Section 15, to (x) obtain Replacement Class
Interest Rate Caps or Qualified Substitute Cap Arrangements or (y) cause the Interest Rate Cap Provider to pledge securities as collateral securing the obligations of the Interest Rate Cap Provider as provided in Section 15, in each case
in a manner satisfactory to the Trustee and the Rating Agencies (such that neither Rating Agency will reduce or withdraw the ratings of the Investor Certificates of the Series established hereby); or 
 (d) if a Supplemental Credit Enhancement Event shall have occurred and Discover Bank as Servicer shall have failed to arrange for the Supplemental Credit
Enhancement in accordance with the requirements of Section 11(c) hereof (including, without limitation, receipt of the confirmation from Standard & Poor’s required thereby); 
 an Amortization Event shall occur with respect to the Investor Certificates of the Series established hereby, immediately upon the occurrence of such event. If an
Amortization Event described in this Section 18 shall occur, this Section 18 constitutes written notice by the Trustee and not less than 51% of the Class Invested Amount of each Class of the Series established hereby to the Master Servicer
and the Sellers that such Amortization Event has occurred. No additional notice of any kind, which is hereby waived by the Seller and the Master Servicer, shall be required as a condition of the occurrence of any Amortization Event described in this
Section 18. 
 SECTION 19. Purchase of Investor Certificates and Series Termination. 
 (a) If as of any Distribution Date during the Amortization Period (after giving effect to any payments calculated pursuant to Section 9 made on such
Distribution Date) the Series Investor Interest of the Series established hereby is less than or equal to 5% of the Series Initial Investor Interest, Discover Bank on behalf of the Holder of the Seller Certificate may purchase and cancel the
Investor Certificates of the Series established hereby by depositing into the Series Distribution Account, on the immediately succeeding Distribution Date, an amount equal to the Series Investor Interest as of the last day of the Due Period related
to such immediately succeeding Distribution Date. The amount deposited pursuant to this Section 19(a) that is allocable to the Investor Certificateholders shall be paid to the Investor Certificateholders pursuant to Section 12.02 of the
Pooling and Servicing Agreement on the Distribution Date of such deposit. All Investor Certificates of the Series established hereby that are purchased by Discover 

  

 57 

 
Bank on behalf of the Holder of the Seller Certificate pursuant to this Section 19(a) shall be delivered by Discover Bank on behalf of the Holder of the
Seller Certificate upon such purchase to, and be cancelled by, the Transfer Agent and be disposed of in a manner satisfactory to the Trustee and Discover Bank on behalf of the Holder of the Seller Certificate. 
 (b) If as of any Distribution Date during the Accumulation Period or the Controlled Liquidation Period, as applicable (after giving effect to any
payments calculated pursuant to Section 9 made on such Distribution Date), the Series Investor Interest of the Series established hereby is less than or equal to 5% of the Series Initial Investor Interest (before giving effect to any reduction
in the Series Initial Investor Interest pursuant to Section 6.14 of the Pooling and Servicing Agreement), Discover Bank on behalf of the Holder of the Seller Certificate may, but shall not be obligated to, purchase the Investor Certificates of
the Series established hereby by depositing into the Series Principal Funding Account, on such Distribution Date, an amount equal to such Series Investor Interest. After giving effect to such deposit, such Series Investor Interest shall be reduced
to zero, and the Seller Interest shall be increased by the amount of such deposit. 
 SECTION 20. Variable Accumulation Period. If the
Series Term Sheet for the Series established hereby so provides, the Master Servicer may elect, by written notice to the Trustee, Discover Bank on behalf of the Holder of the Seller Certificate and the Credit Enhancement Provider, to delay the
commencement of the Accumulation Period, and extend the length of the Revolving Period, subject to the conditions set forth in this Section 20; provided, however, that the Accumulation Period shall commence no later than the first
day of the Due Period related to the Class A Expected Final Payment Date. Any such election by the Master Servicer shall be made no later than the first day of the last scheduled Due Period of the Revolving Period (including any prior extension
of the Revolving Period pursuant to this Section 20). 
 The Master Servicer may make such election only if the following conditions are
satisfied: (i) the Master Servicer shall have delivered to the Trustee a certificate to the effect that the Master Servicer reasonably believes that the delay in the commencement of the Accumulation Period would not result in the Class Invested
Amount with respect to any Class of the Series established hereby not being paid in full on the relevant Class Expected Final Payment Date; (ii) the Rating Agencies shall have advised the Master Servicer and Discover Bank on behalf of the
Holder of the Seller Certificate that such election to delay the commencement of the Accumulation Period would not cause the rating of any Class of any Series then outstanding to be lowered or withdrawn; and (iii) the amount to be deposited in
the Series Principal Funding Account in respect of the Accumulation Amount shall have been adjusted. 
 SECTION 21. [Reserved].

 SECTION 22. Ratification of Pooling and Servicing Agreement. As supplemented and amended by this Series Supplement, the Pooling and
Servicing Agreement is in all respects ratified and confirmed and the Pooling and Servicing Agreement as so supplemented by this Series Supplement shall be read, taken, and construed as one and the same instrument. 
  

 58 

 SECTION 23. Counterparts. This Series Supplement may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all of such counterparts shall together constitute but one and the same instrument. 
 SECTION 24. Governing Law. This Series Supplement 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. 
 SECTION 25.
Intention of Parties. The parties intend the sale, transfer, assignment or conveyance of Receivables, Interchange and all proceeds thereof 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. 
 SECTION 26. Election Under Delaware Asset-Backed Securities Facilitation Act. Without limiting any other provisions of the Pooling and Servicing Agreement or this Series Supplement, the parties hereto agree

Interchange (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 Seller;
(2) the Seller, its creditors or, in any insolvency proceeding with respect to the Seller or the Seller’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 Seller any of the Transferred Assets; and (3) in the event of a bankruptcy, receivership or other insolvency proceeding with respect to

 [FORM OF THE REVERSE OF THE CLASS A CERTIFICATES] 
 It is the intent of the Sellers and the Investor Certificateholders that, for federal, state and local income and franchise tax purposes only, the
Investor Certificates will be evidence of indebtedness of the Sellers. The Sellers and the Class A Certificateholder, by the acceptance of this Class A Certificate, agree to treat this Class A Certificate for federal, state and local
income and franchise tax purposes as indebtedness of the Sellers secured by the Receivables and other assets held in the Trust. 
 To the
extent not defined herein, the capitalized terms used herein have the meanings assigned in the Pooling and Servicing Agreement or the Series Supplement. This Class A Certificate is issued under and is subject to the terms, provisions and
conditions of the Pooling and Servicing Agreement and the Series Supplement, to which Pooling and Servicing Agreement and Series Supplement, as each may be amended from time to time, the Class A Certificateholder by virtue of the acceptance
hereof assents and by which the Class A Certificateholder is bound. 
 This Class A Certificate is one of a series of Certificates
entitled “Discover Card Master Trust I, Series 1996-4 Floating Rate Class A Credit Card Pass-Through Certificates” (the “Class A Certificates”), each of 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 and the Series Supplement to be deposited in the Investor Accounts with respect to Discover Card Master Trust I,
Series 1996-4 or paid to the Class A Certificateholders. Also issued under the Pooling and Servicing Agreement and the Series Supplement are Investor Certificates designated as “Discover Card Master Trust I, Series 1996-4 Floating Rate
Class B Credit Card Pass-Through Certificates” (the “Class B Certificates”). The Class A Certificates and the Class B Certificates are collectively referred to herein as the Investor Certificates. 
 The aggregate interest represented by the Class A Certificates at any time in the assets of the Trust shall not exceed an amount equal to the
Class A Investor Interest at such time, plus accrued but unpaid Certificate Interest for the Class A Certificates and any interest thereon. The Class Initial Investor Interest of the Class A Certificates is $1,000,000,000. The
Class A Invested Amount on any Distribution Date will be an amount equal to the Class A Initial Investor Interest minus the sum of (a) the aggregate amount of payments of Certificate Principal paid to the Class A
Certificateholders prior to such Distribution Date, (b) the aggregate amount of Investor Losses for such Class not reimbursed prior to such Distribution Date and (c) the aggregate amount of losses of principal on investments in funds on
deposit for the benefit of such Class in the Series Principal Funding Account. In addition to the Investor Certificates, a Seller Certificate has been issued pursuant to the Pooling and Servicing Agreement which represents, at any time, the
undivided interest in the Trust not represented by the Investor Certificates or the investor certificates of any other Series of investor certificates then outstanding. Subject to the terms and conditions of the Pooling and Servicing Agreement, the
Sellers may from time to time direct the Trustee, on behalf of the Trust, to issue one or more new Series of investor certificates, which will represent Fractional Undivided Interests in the Trust. 
  

 A-1-4 

 During the Revolving Period, which begins on the Series Cut-Off Date, and during the Accumulation Period,
Certificate Interest will be distributed on the 15th day of each calendar month with respect to interest accrued during the preceding Interest Accrual Period, commencing in May 1996, or if such 15th day is not a Business Day, on the next succeeding
Business Day (an “Interest Payment Date”), to the Class A Certificateholders of record as of the last day of the month preceding the related Interest Payment Date. Principal on the Class A Certificates will be paid in a single
payment on the Distribution Date in April 2011 (the “Class A Expected Final Payment Date”), but may be paid sooner or later and in installments if an Amortization Event occurs. During the Amortization Period, if any, Certificate Interest
and Certificate Principal collected by the Master Servicer will be distributed to the Class A Certificateholders on the Distribution Date of each calendar month, commencing in the month following the commencement of the Amortization Period. In
any event, the final payment of principal of either class will be made no later than October 16, 2013 (the “Series Termination Date”). 
 The amount to be distributed on each Distribution Date to the holder of this Class A Certificate will be equal to the product of (a) the percentage equivalent of a fraction, the numerator of which is the
portion of the Class A Initial Investor Interest evidenced by this Class A Certificate and the denominator of which is the Class A Initial Investor Interest and (b) the aggregate of all payments to be made to the Class A
Certificateholders on such Distribution Date. Distributions with respect to this Class A Certificate will be made by the Paying Agent by check mailed to the address of the Class A Certificateholder of record appearing in the Certificate
Register (except for the final distribution in respect of this Class A Certificate) without the presentation or surrender of this Class A Certificate or the making of any notation thereon, except that with respect to Class A
Certificates registered in the name of CEDE & CO., the nominee registrant for The Depository Trust Company, distributions will be made in the form of immediately available funds. 
 This Class A Certificate does not represent an obligation of, or an interest in, the Master Servicer. This Class A Certificate is limited in
right of payment to certain Collections respecting the Receivables and certain other assets of the Trust, all as more specifically set forth hereinabove and in the Pooling and Servicing Agreement and the Series Supplement. 
 The Pooling and Servicing Agreement permits, with certain exceptions, the amendment and modification of the rights and obligations of the Master
Servicer, and the rights of Investor Certificateholders under the Pooling and Servicing Agreement and Series Supplement, at any time by the Master Servicer, the Sellers and the Trustee in certain cases (some of which require confirmation from the
Rating Agencies that such amendment will not result in the downgrading or withdrawal of the rating assigned to the Investor Certificates) without the consent of the Investor Certificateholders, and in all other cases with the consent of the Investor
Certificateholders owning Fractional Undivided Interests aggregating not less than 66-2/3% of the Class Invested Amount of each such affected Class (and with confirmation from the Rating Agencies that such amendment will not result in the
downgrading or withdrawal of the rating assigned to the Investor Certificates); provided, however, that no such amendment shall (a) have a material adverse effect on any Class of Investor Certificateholders by reducing in any
manner the amount of, or delaying the timing of, distributions which are required to be made on any Investor Certificate without the consent of the affected Investor Certificateholders or (b) reduce the aforesaid percentage required to consent
to any such amendment, without the consent of each Investor 

  

 A-1-5 

 
Certificateholder of each affected Class then of record. Any such amendment and any such consent by the Class A Certificateholder shall be conclusive
and binding on such Class A Certificateholder and upon all future Holders of this Class A Certificate and of any Class A Certificate issued in exchange hereof or in lieu hereof whether or not notation thereof is made upon this
Class A Certificate. 
 The transfer of this Class A Certificate shall be registered in the Certificate Register upon surrender of
this Investor Certificate for registration of transfer at any office or agency maintained by the Transfer Agent and Registrar accompanied by a written instrument of transfer in a form satisfactory to the Trustee and the Transfer Agent and Registrar
duly executed by the Class A Certificateholder or such Class A Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Class A Certificates of authorized denominations and for the same aggregate
Fractional Undivided Interest will be issued to the designated transferee or transferees. 
 As provided in the Pooling and Servicing
Agreement and subject to certain limitations therein set forth, Class A Certificates are exchangeable for new Class A Certificates evidencing like aggregate Fractional Undivided Interests, as requested by the Class A Certificateholder
surrendering such Class A Certificates. No service charge may be imposed for any such exchange but the Master Servicer or Transfer Agent and Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection therewith. 
 The Master Servicer, the Trustee, the Paying Agent and the Transfer Agent, and any agent of any of
them, may treat the person in whose name this Class A Certificate is registered as the owner hereof for all purposes, and neither the Master Servicer, the Trust nor the Trustee, the Paying Agent, the Transfer Agent, nor any agent of any of them
or any such agent shall be affected by notice to the contrary except in certain circumstances described in the Pooling and Servicing Agreement. 
 Subject to certain conditions in the Pooling and Servicing Agreement and the Series Supplement, if the principal of the Investor Certificates has not been paid in full prior to the Series Termination Date, the obligations created by the
Pooling and Servicing Agreement and the Series Supplement with respect to the Investor Certificates shall terminate on the Series Termination Date.

 [FORM OF THE REVERSE OF THE CLASS B CERTIFICATES] 
 It is the intent of the Sellers and the Investor Certificateholders that, for federal, state and local income and franchise tax purposes only, the
Investor Certificates will be evidence of indebtedness of the Sellers. The Sellers and the Class B Certificateholder, by the acceptance of this Class B Certificate, agree to treat this Class B Certificate for federal, state and local income and
franchise tax purposes as indebtedness of the Sellers secured by the Receivables and other assets held in the Trust. 
 To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in the Pooling and Servicing Agreement or the Series Supplement. This Class B Certificate is issued under and is subject to the terms, provisions and conditions of the
Pooling and Servicing Agreement and the Series Supplement, to which Pooling and Servicing Agreement and Series Supplement, as each may be amended from time to time, the Class B Certificateholder by virtue of the acceptance hereof assents and by
which the Class B Certificateholder is bound. 
 This Class B Certificate is one of a series of Certificates entitled “Discover Card
Master Trust I, Series 1996-4 Floating Rate Class B Credit Card Pass-Through Certificates” (the “Class B Certificates”), each of 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 and the Series Supplement to be deposited in the Investor Accounts with respect to Discover Card Master Trust I, Series 1996-4 or paid to
the Class B Certificateholders. Also issued under the Pooling and Servicing Agreement and the Series Supplement are Investor Certificates designated as “Discover Card Master Trust I, Series 1996-4 Floating Rate Class A Credit Card
Pass-Through Certificates” (the “Class A Certificates”). The Class A Certificates and the Class B Certificates are collectively referred to herein as the Investor Certificates. 
 The aggregate interest represented by the Class B Certificates at any time in the assets of the Trust shall not exceed an amount equal to the Class
Investor Interest of the Class B Certificates at such time, plus accrued but unpaid Certificate Interest for the Class B Certificates and any interest thereon. The Class B Certificateholders are also entitled to the benefit of the Credit
Enhancement, to the extent provided in the Series Supplement. The Class Initial Investor Interest of the Class B Certificates is $52,632,000. The Class B Invested Amount on any Distribution Date will be an amount equal to the Class B Initial
Investor Interest minus the sum of (a) the aggregate amount of payments of Certificate Principal paid to the Class B Certificateholders prior to such Distribution Date, (b) the aggregate amount of Investor Losses for such Class not
reimbursed prior to such Distribution Date and (c) the aggregate amount of losses of principal on investments in funds on deposit for the benefit of such Class in the Series Principal Funding Account. In addition to the Investor Certificates, a
Seller Certificate has been issued pursuant to the Pooling and Servicing Agreement which represents, at any time, the undivided interest in the Trust not represented by the Investor Certificates or the investor certificates of any other Series of
investor certificates then outstanding. Subject to the terms and conditions of the Pooling and Servicing Agreement, the Sellers may from time to time direct the Trustee, on behalf of the Trust, to issue one or more new Series of investor
certificates, which will represent Fractional Undivided Interests in the Trust. 
  

 A-2-4 

 During the Revolving Period, which begins on the Series Cut-Off Date, and during the Accumulation Period,
Certificate Interest will be distributed on the 15th day of each calendar month with respect to interest accrued during the preceding Interest Accrual Period, commencing in May 1996, or if such 15th day is not a Business Day, on the next succeeding
Business Day (an “Interest Payment Date”), to the Class B Certificateholders of record as of the last day of the month preceding the related Interest Payment Date. Principal on the Class B Certificates will be paid in a single payment on
the Distribution Date in May 2011 (the “Class B Expected Final Payment Date), but may be paid sooner or later and in installments if an Amortization Event occurs. During the Amortization Period, if any, Certificate Interest and Certificate
Principal collected by the Master Servicer will be distributed to the Class B Certificateholders on the Distribution Date of each calendar month, commencing in the month following the commencement of the Amortization Period; provided,
however, that no Certificate Principal will be distributed to the Class B Certificateholders until the Class A Investor Interest has been reduced to zero. The rights of the Class B Certificateholders to receive the distributions to which
they would otherwise be entitled on the Receivables will be subordinated to the rights of the Class A Certificateholders and the Master Servicer to the extent described in the Pooling and Servicing Agreement and Series Supplement. In any event,
the final payment of principal of either Class will be made no later than October 16, 2013 (the “Series Termination Date”). 
 The amount to be distributed on each Distribution Date to the holder of this Class B Certificate will be equal to the product of (a) the percentage equivalent of a fraction, the numerator of which is the portion of the Class B Initial
Investor Interest evidenced by this Class B Certificate and the denominator of which is the Class B Initial Investor Interest and (b) the aggregate of all payments to be made to the Class B Certificateholders on such Distribution Date.
Distributions with respect to this Class B Certificate will be made by the Paying Agent by check mailed to the address of the Class B Certificateholder of record appearing in the Certificate Register (except for the final distribution in respect of
this Class B Certificate) without the presentation or surrender of this Class B Certificate or the making of any notation thereon, except that with respect to Class B Certificates registered in the name of CEDE & CO., the nominee registrant
for The Depository Trust Company, distributions will be made in the form of immediately available funds. 
 This Class B Certificate does not
represent an obligation of, or an interest in, the Master Servicer. This Class B Certificate is limited in right of payment to certain Collections respecting the Receivables and certain other assets of the Trust, all as more specifically set forth
hereinabove and in the Pooling and Servicing Agreement and the Series Supplement. 
 The Pooling and Servicing Agreement permits, with
certain exceptions, the amendment and modification of the rights and obligations of the Master Servicer, and the rights of Investor Certificateholders under the Pooling and Servicing Agreement and Series Supplement, at any time by the Master
Servicer, the Sellers and the Trustee in certain cases (some of which require confirmation from the Rating Agencies that such amendment will not result in the downgrading or withdrawal of the rating assigned to the Investor Certificates) without the
consent of the Investor Certificateholders, and in all other cases with the consent of the Investor Certificateholders owning Fractional Undivided Interests aggregating not less than 66-2/3% of the Class Invested 

  

 A-2-5 

 
Amount of each such affected Class (and with confirmation from the Rating Agencies that such amendment will not result in the downgrading or withdrawal of
the rating assigned to the Investor Certificates); provided, however, that no such amendment shall (a) have a material adverse effect on any Class of Investor Certificateholders by reducing in any manner the amount of, or delaying
the timing of, distributions which are required to be made on any Investor Certificate without the consent of the affected Investor Certificateholders or (b) reduce the aforesaid percentage required to consent to any such amendment, without the
consent of each Investor Certificateholder of each affected Class then of record. Any such amendment and any such consent by the Class B Certificateholder shall be conclusive and binding on such Class B Certificateholder and upon all future Holders
of this Class B Certificate and of any Class B Certificate issued in exchange hereof or in lieu hereof whether or not notation thereof is made upon this Class B Certificate. 
 The transfer of this Class B Certificate shall be registered in the Certificate Register upon surrender of this Investor Certificate for registration of
transfer at any office or agency maintained by the Transfer Agent and Registrar accompanied by a written instrument of transfer in a form satisfactory to the Trustee and the Transfer Agent and Registrar duly executed by the Class B Certificateholder
or such Class B Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Class B Certificates of authorized denominations and for the same aggregate Fractional Undivided Interest will be issued to the designated
transferee or transferees. 
 The transfer of this Investor Certificate is subject to certain restrictions set forth in the Pooling and
Servicing Agreement. In no event shall this Investor Certificate, or any interest therein, be transferred to 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)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), and not excepted under Section 4975(g). Any Holder of this Investor Certificate, by its acceptance hereof, 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 Title I of ERISA, (ii) a plan described in Section 4975(e)(1) of the Code, and not excepted under
Section 4975(g), or (iii) an entity using assets to purchase such Certificates which constitute plan assets by reason of a plan’s investment in such Holder. 
 As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, Class B Certificates are exchangeable for new
Class B Certificates evidencing like aggregate Fractional Undivided Interests, as requested by the Class B Certificateholder surrendering such Class B Certificates. No service charge may be imposed for any such exchange but the Master Servicer or
Transfer Agent and Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 
 The Master Servicer, the Trustee, the Paying Agent and the Transfer Agent, and any agent of any of them, may treat the person in whose name this Class B Certificate is registered as the owner hereof for all purposes,
and neither the Master Servicer, the Trust nor the Trustee, the Paying Agent, the Transfer Agent, nor any agent of any of them or any such agent shall be affected by notice to the contrary except in certain circumstances described in the Pooling and
Servicing Agreement.

 Subject to certain conditions in the Pooling and Servicing Agreement and the Series Supplement, if the

on the Series Termination Date.

 The Discover Card Master Trust I is required to maintain Principal Receivables greater than or equal to the Minimum Principal Receivables Balance. The Minimum Principal Receivables Balance is generally calculated by
dividing the Investor Interest by 93%. If the Principal Receivables in the Trust are less than the Minimum Principal Receivables Balance, and Discover Bank fails to assign sufficient Receivables to eliminate the deficiency, then an amortization
event would occur.

	2	 Only the portion of Trust Collections
required to be deposited under the Trust’s Required Daily Deposit provisions will typically be deposited in the Trust Collections Account each month, and these required amounts may vary markedly from month to month depending on whether any
Investor Certificates are maturing on the following distribution date (in which case additional Principal Collections are retained in such account). Accordingly, the amount deposited in the account is not meaningful as an indicator of Trust
performance. 

  

	3	 Investors should refer only to the
higher of the Group Excess Spread Percentage (Item 16(a)), the Interchange Subgroup Excess Spread Percentage (Item 16(c)) and the Series Excess Spread Percentage (Item 16(b)) in assessing the current performance of the Trust and the Receivables.
If necessary, the Trust will use funds available from series or subseries with positive Series Excess Spreads to cover expenses (as detailed in note 5 below) for series or subseries, if any, with negative Series Excess Spreads, except that any such
funds consisting of Interchange will only be used to cover expenses for Interchange Series. The Group Excess Spread Percentage reflects the aggregate amount of Series Excess Spread remaining after all Trust expenses for all series, including each
subseries, have been paid or reimbursed, including expenses paid or reimbursed through such reallocations of Series Excess Spread. The Group Excess Spread Percentage expresses this amount as a percentage of the Aggregate Investor Interest in the
Trust as of the beginning of the month. 

  

	4	 Group Excess Spread is the sum of the Series
Excess Spreads for each series, including each subseries, in the Group. The Group Excess Spread Percentage is equal to the Group Excess Spread, multiplied by twelve, divided by the Series Investor Interests at the beginning of the
period for each series, including each subseries, in the Group. 

  

	5	 The Interchange Subgroup Excess Spread
Percentage is the sum of (i) all amounts deposited into the Group Interchange Reallocation Account for all Interchange Series and (ii) the Interchange Subgroup Allocable Group Excess Spread (as such term is defined in the Series Supplement between
Discover Bank and U.S. Bank National Association, as Trustee, for each series, including each subseries), multiplied by twelve, divided by the Series Investor Interest for all Interchange Series at the beginning of each period.

  

	6	 Series Excess Spread for this subseries is
the difference between (a) the sum of Finance Charge Collections, Investment Income and Series Interchange for any Class of this subseries (see Item 3(c)), and (b) the sum of (i) the monthly interest for this subseries (see “Deposits into the
SIFA on this Distribution Date” in Item 6), (ii) the monthly servicing fee for this subseries (see Item 12(b)), (iii)

	    	the Investor Charged-Off Amount (see Item 8(b)), and (iv) the Credit Enhancement Fee (see Item 14(d)), in each case for this Distribution Date. For purposes of determining Group
Excess Spread and the Interchange Subgroup Shortfall Allocation Percentage, Series Excess Spread is the amount calculated as described above minus if the Series Excess Spread for such subseries is positive, the lesser of Series Interchange or the
amount determined as the Series Excess Spread without giving effect to this sentence; provided that Series Excess Spread, for purposes of determining the Group Excess Spread and the Interchange Subgroup Shortfall Allocation Percentage, shall not be
reduced below zero as a result of this sentence. The Series Excess Spread Percentage is equal to the Series Excess Spread, multiplied by twelve, divided by the Series Investor Interest for this subseries at the beginning of the period.

  

	7	 For purposes of allocations to investors,
all recoveries are treated as Finance Charge Collections and are included as such in Item 3 above.
