	 	(x)	 	the Principal Distribution Amount and
	 
	 	(y)	 	the amount deposited into the Series Principal
Funding Account on such Special Payment Date pursuant to Section 9





shall be withdrawn from the Series Principal Funding Account. The Master Servicer shall cause the
Paying Agent to pay such amount to the Investor Certificateholders of such Class or Subclass in
accordance with Section 5.01 of the Pooling and Servicing Agreement. Except as set forth in the
following sentence, all such amounts shall be paid to or with respect to the Class A Investor
Certificateholders until the Class A Invested Amount is reduced to zero; and, thereafter, if there
is a Subordinate Class with respect to Class A, such amounts shall be paid to or with respect to
the Class B Investor Certificateholders until the Class B Invested Amount is reduced to zero,
unless the Series Termination Date occurs prior to such date. In no event shall any amounts be
paid with respect to any Class of Investor Certificates pursuant to this clause (7) in excess of
the Class Invested Amount for such Class. Any amounts remaining on deposit in the Series Principal
Funding Account after the Class Invested Amount for each Class has been reduced to zero shall be
paid to the Holder of the Seller Certificate.



          (8) On the first Distribution Date of the Amortization Period, if any, after giving effect to
the payments and withdrawals and conversions described above on such day, an amount equal to the
lesser of





	 	(x)	 	the Series Invested Amount and
	 
	 	(y)	 	the amount on deposit in the Series Principal
Funding Account





shall be withdrawn from the Series Principal Funding Account. The Master Servicer shall cause the
Paying Agent to pay such amount to the Investor Certificateholders of such Class or Subclass in
accordance with Section 5.01 of the Pooling and Servicing Agreement. Except as set forth in
the following sentence, all such amounts shall be paid to or with respect to the Class A Investor
Certificateholders until the Class A Invested Amount is reduced to zero; and, thereafter, if there
is a Subordinate Class with respect to Class A, such amounts shall be paid to or with respect to
the Class B Investor Certificateholders until the Class B Invested Amount is reduced to zero,
unless the Series Termination Date occurs prior to such date. In no event shall any amounts be
paid with respect to any Class of Investor Certificates pursuant to this clause (8) in excess of
the Class Invested Amount for such Class. Any amounts remaining on deposit in the Series Principal
Funding Account after the Class Invested Amount for each Class has been reduced to zero shall be
paid to the Holder of the Seller Certificate.



          (9) On the Class Expected Final Payment Date or the Class Final Maturity Date, if applicable
(or, if such Class Expected Final Payment Date or Class Final Maturity Date

52









 









is not also a
Distribution Date, on the Distribution Date occurring in the same calendar month as the Class
Expected Final Payment Date or the Class Final Maturity Date, if applicable), the Master Servicer
shall direct the Trustee in writing to withdraw the amount on deposit in the Series Principal
Funding Account with respect to each Class; provided that (i) such amount shall be no greater than
the Class Invested Amount and (ii) funds, if any, remaining on deposit in the Series Principal
Funding Account after the payment in full of the Class Invested Amount with respect to each Class
shall be withdrawn and paid to the Holder of the Seller Certificate. The Master Servicer shall
cause the Paying Agent to pay such amount to the Investor Certificateholders of such Class or
Subclass in accordance with Section 5.01 of the Pooling and Servicing Agreement.



     (b) Payments to the Sellers and/or the Master Servicer. Notwithstanding the other provisions
in Section 9 and this Section 10, any amounts payable to Discover Bank on behalf of the Holder of
the Seller Certificate or to the Master Servicer on any Distribution Date pursuant to Section 9 and
this Section 10 may be paid prior to such Distribution Date pursuant to Section 4.03(d) of the
Pooling and Servicing Agreement.



     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 Master Servicer without
penalty if (x) the Master Servicer elects to obtain a successor Credit Enhancement, provided that
such termination does not cause the ratings of the Investor Certificates to be lowered or withdrawn
by either of the Rating Agencies and, provided, further, that all amounts owing to the Credit
Enhancement Provider under the respective Credit
Enhancement Agreement with respect to principal and interest on the Credit Enhancement have
been paid in full 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



53









 





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.



     (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 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.



54









 





     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 Early Accumulation Period or 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 Early Accumulation Event or 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 Early Accumulation
Event or the Amortization Event occurs;




     (iii) prior to the last day of the Revolving Period (or, following an Early
Accumulation Event or an Amortization Event during the Revolving Period, on or prior to the
last day of the Due Period in which the Early Accumulation Event or 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 Early Accumulation
Event or an Amortization Event during the Revolving Period, on or prior to the last day of
the Due Period in which the Early Accumulation Event or 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.



     (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



55









 







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 Charge-Off 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 (after giving effect to any increase
therein pursuant to Section 31) 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 Certificate
Principal 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



     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



56









 







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.



     (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



57









 







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) 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. Class Interest Rate Swaps. In the event that the Investor Certificates of any
Class are subject to a Class Interest Rate Swap, the Trust will enter into a Class Interest Rate
Swap in a form approved by the Master Servicer. Pursuant to the terms of the Class Interest Rate
Swap, the Interest Rate Swap Counterparty shall pay to the Trust the Net Swap Receipt or the Trust
shall pay to the Interest
Rate Swap Counterparty the Net Swap Payment, as applicable. If the Trust does not receive
payment from the Interest Rate Swap Counterparty on each Interest Payment Date (if due), the
Trustee, on behalf of the Trust, shall attempt to determine from the Interest Rate Swap
Counterparty the reasons therefore and whether such payment is to be made by the Interest Rate Swap
Counterparty on such Interest Payment Date. If the Class Interest Rate Swap has not been
terminated and the Trust has not received any payment due from the Interest Rate Swap Counterparty
on the related Interest Payment Date, the Trustee shall notify the Master Servicer of such fact
prior to 1:00 p.m. Chicago time on such Interest Payment Date.



     SECTION 17. Investor Certificateholders’ Monthly Statement. On each Statement Date, a
statement substantially in the form of Exhibit B as prepared by the Trustee (based on information
provided by the Master Servicer) setting forth the information listed thereon shall be available
from the Trustee, each Paying Agent and, if applicable, the Listing Agent.



     SECTION 18. Master Servicer’s Monthly Certificate. On or before the second Business Day
preceding each Statement Date, the Master Servicer shall forward to Discover Bank on behalf of the
Holder of the Seller Certificate, the Trustee and each Paying Agent a certificate of a Servicing
Officer substantially in the form of Exhibit C setting forth the information listed thereon.



58









 





     SECTION 19. Notices. Any notices to holders of Investor Certificates issued in bearer form
shall be given as described in the Series Term Sheet.



     SECTION 20. Additional Amortization Events. If any one of the following events shall occur:



     (a) 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;



     (b) 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 or establish any other arrangement 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



     (c) if the amount of Principal Receivables in the Trust at the end of any Due Period for three
consecutive Due Periods of the Early Accumulation Period shall be less than the Minimum Principal
Receivables Balance and Discover Bank shall have failed to assign Receivables in Additional
Accounts or Participation Interests to the Trust in at least the amount of the deficiency by the
tenth day of the calendar month of the following Due Period;



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 20 shall occur, this Section 20 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 Sellers and the Master Servicer, shall be
required as a condition of the occurrence of any Amortization Event described in this Section 20.
In addition, the events set forth in Section 21 shall constitute either Early Accumulation Events
or additional Amortization Events with respect to the Series established hereby.



     SECTION 21. Early Accumulation Events; Additional Amortization Events. If the Series
established hereby is eligible to have an Early Accumulation Period, each of the events described
in clause (a), (b), (g), (i) or (j) of Section 9.01 of the Pooling and Servicing Agreement shall
not be Amortization Events but shall instead be Early Accumulation Events. In addition, for
purposes of this Series Supplement, each of the following events shall be (i) Early Accumulation
Events, if the Series established hereby is eligible to have an Early Accumulation Period, or (ii)



59









 







Amortization Events, if the Series established hereby is not eligible to have an Early Accumulation
Period:



     (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;



     (b) 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).



If any event described in clause (a), (b), (g), (i) or (j) of Section 9.01 of the Pooling and
Servicing Agreement occurs, an Early Accumulation Event shall occur with respect to the Investor
Certificates of such Class only if the event has a material adverse effect on the Investor
Certificateholders of such Class and if, after the applicable grace period described in those
clauses, either the Trustee declares or the Investor Certificateholders of such Class evidencing
Fractional Undivided Interests aggregating not less than 51% of the Class Invested Amount for
either Class declare by written notice to Discover Bank and the Master Servicer (and to the Trustee
if given by the Investor Certificateholders) that an Early Accumulation Event has occurred as of
the date of the notice. In the case of any event described in clause (a) or (b) of this Section
21, either an Early Accumulation Event or an Amortization Event shall occur with respect to the
Investor Certificates of such Class immediately upon the occurrence of the event without any notice
or other action on the part of the Trustee or the Investor Certificateholders of such Class. On
the date on which such Early Accumulation Event or Amortization Event is deemed to have occurred,
the Early Accumulation Period or Amortization Period, as applicable, will commence.



     SECTION 22. 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 Master Servicer shall direct the Trustee in writing to withdraw
the amount allocable to such Class from the Series Distribution Account and pay such amount to the
Investor Certificateholders of such Class pursuant to Section 12.02 of the Pooling and Servicing
Agreement. All Investor Certificates of the Series established hereby that are purchased by
Discover Bank on behalf of the Holder of the Seller Certificate pursuant to this Section 22(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



60









 







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, the Early 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.



     (c) Following the sale of Receivables pursuant to Section 12.02 of the Pooling and Servicing
Agreement, the Master Servicer shall direct the Trustee in writing to withdraw the
amount allocable to each Class from the Series Distribution Account and pay such amount to the
Investor Certificateholders of such Class pursuant to Section 12.02 of the Pooling and Servicing
Agreement.



     SECTION 23. 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 23; 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 23).



     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, based on the payment rate and the availability of
reallocated Principal Collections, 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 24. Optional Accumulation Period Commencement. If the Series Term Sheet for the
Series established hereby so provides, unless the Amortization Period or the Early Accumulation
Period shall have commenced prior thereto, the Master Servicer may elect to



61









 







commence the
Accumulation Period by delivering written notice to the Trustee, Discover Bank, on behalf of the
Holder of the Seller Certificate and the Credit Enhancement Provider at least 5 Business Days prior
to the Accumulation Commencement Date subject to the conditions set forth in this Section 24;
provided, however, that the Accumulation Period shall commence no later than the first day of the
following Due Period. Such written notice shall set forth the Accumulation Amount for each
Distribution Date relating to the Accumulation Period.



     SECTION 25. 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.



     SECTION 26. 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 27. Governing Law. This Series Supplement and all disputes arising out of or relating
to it shall be construed in accordance with the internal laws of the State of New York, without
reference to its conflict of law provisions that would result in the application of the law of any
state other than New York, and the obligations, rights and remedies of the parties hereunder shall
be determined in accordance with such laws.



     SECTION 28. 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 and an absolute transfer for all purposes
(other than for federal, state and local income and franchise tax purposes). The parties intend
the sale, transfer, assignment or conveyance of Receivables in connection herewith to be treated as
a sale for accounting purposes.



     SECTION 29. Amendment for Sale Accounting Purposes. If any Seller determines that (i) an
amendment to this Agreement or the Pooling and Servicing Agreement is necessary or desirable for
such Seller to maintain or establish sale accounting treatment under then-applicable financial
accounting standards, and (ii) such Seller cannot enter into such amendment pursuant to Section
13.01 of the Pooling and Servicing Agreement without obtaining the consent of a specified
percentage of Investor Certificateholders, then the Master Servicer, the Sellers, the Trustee and
the Servicers may nonetheless enter into such amendment without obtaining the consent of any
Certificateholder of any Investor Certificates of this Series so long as the Trustee shall have
been advised by the Rating Agencies that such amendment will not result in the downgrading or
withdrawal of the rating assigned to any Class of any Series then outstanding.



     Any such amendment may include, without limitation, any changes necessary to convert the Trust
from a “one-tier” securitization structure to a “two-tier” securitization structure.
Notwithstanding the foregoing, any Investor Certificateholder that acquires an Investor Certificate
of this Series will be deemed to have consented to any such amendment for all purposes, including
for purposes of calculating whether the requisite consent percentage, if any, under Section 13.01
of the Pooling and Servicing Agreement has been received for any



62









 







amendment that requires such
consent because of the lack of provisions comparable to this Section 29 in the Series Supplements
for other Series then outstanding (except that Investor Certificates beneficially owned by any
Seller or any affiliate or agent of any Seller will not be included in any such calculation).



     SECTION 30. 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 that (a) the transactions contemplated hereby constitute a “securitization
transaction” and (b) to the fullest extent permitted under applicable law, including without
limitation, the Asset-Backed Securities Facilitation Act Delaware Code Ann. tit. 6, § 2703A et seq:
(1) all right, title and interest to the Receivables, whether now existing or hereafter acquired,
all monies due or to become due with respect thereto, all proceeds of such Receivables and all
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 the Seller or the Seller’s property, such Transferred Assets shall not
be deemed to be part of the Seller’s property, assets, rights or estate.



     SECTION 31. Issuance of Additional Certificates. The Sellers may direct the Trustee to
issue, at any time and from time to time when this Series is outstanding, additional Investor
Certificates of this Series to increase the Series Investor Interest, subject to the satisfaction
of the conditions described below:



     (a) The additional Investor Certificates shall increase the Class Invested Amounts of the
Class A Certificates and the Class B Certificates, if applicable, and all amounts related to the
Credit Enhancement for this Series proportionately from their initial levels.



     (b) The Sellers shall have notified the Trustee, in writing, at least three days in advance of
the date upon which the Series Investor Interest is to be increased, which notice shall state the
designation of the Series under which the additional Investor Certificates are to be issued and
shall include: (i) the amount of Investor Certificates being offered and the resulting Class
Initial Investor Interests and Series Initial Investor Interest; (ii) the date from which interest
on the additional Investor Certificates will accrue (which may be a date prior to the date of
issuance thereof); (iii) the first Interest Payment Date on which interest will be paid on such new
Investor Certificates; (iv) the Increased Credit Enhancement Amount and the Increased Issuance
Subordinated Amount for such increase; and (v) any other terms that the Sellers set forth in such
notice of such increase in the Series Investor Interest to clarify the rights of holders of such
new Investor Certificates or the effect of such new Investor Certificates on any calculations to be
made with respect to this Series, the Group of which this Series is a member, or the Trust. All
such terms shall be incorporated into and form a part of this Series Supplement on and after the
effective date of such increase in the Series Investor Interest. The notice shall also include a



63









 







revised Series Term Sheet that specifies the terms of this Series after giving effect to the
increase.



     (c) The Sellers shall have delivered to the Trustee written confirmation from the Rating
Agencies that they will not, as a result of the increase, change the rating of any class of any
series outstanding at the time of the increase and that they will rate the additional Investor
Certificates the same as those Investor Certificates currently outstanding in this Series.



     (d) Discover Bank as Servicer shall have arranged for the payment of an additional amount
related to the Credit Enhancement required to increase the amount on deposit in the Credit
Enhancement Account so that such amount, after giving effect to such increase and the issuance of
the additional Investor Certificates, represents the same percentage of the Series Investor
Interest that the original amount on deposit in the Credit Enhancement Account, plus any amounts
deposited in the Credit Enhancement Account as a result of a Supplemental Credit Enhancement Event
or an Effective Alternative Credit Support Election, represented of the original Series Investor
Interest (such additional amount, the “Increased Credit Enhancement Amount”). Such payment shall
be made by a Person other than Discover Bank 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 Increased Credit Enhancement Amount shall be determined at
the time it is to be paid.



     (e) Discover Bank on behalf of the Holder of the Seller Certificate shall not be required to
designate Additional Accounts or convey Participation Interests to the Trust pursuant to Section
2.10(a) of the Pooling and Servicing Agreement as a result of the increase in Series Investor
Interest.



     (f) No Amortization Event shall have occurred for this Series.



     (g) No such additional Investor Certificates shall be issued with more than de minimis
original issue discount.



     Upon any increase in the Series Investor Interest, Discover Bank on behalf of the Holder of
the Seller Certificate shall execute and deliver to the Trustee, and the Trustee shall authenticate
and deliver, upon the order of Discover Bank on behalf of the Holder of the Seller Certificate, new
Investor Certificates in the amount of the increase, each of which shall bear, upon its face, the
designation for this Series.

[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 2007-1 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 2007-1 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 2007-1
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 $1,500,000,000; plus the face amount
of any Class A Certificates issued in an increase of the Series Investor Interest pursuant to
Section 31 of the Series Supplement. 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
March 2007, 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 is
scheduled to be paid in a single payment on the Distribution Date in February 2010 (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 the first Business Day following the
Distribution Date in August 2012 (the “Series Termination Date”).



     The amount to be distributed on each Principal Payment 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



A-1-5









 







the aforesaid percentage required to consent to any such amendment, without the consent of
each Investor Certificateholder of each affected Class then of record; and provided, further, that
the permitted activities of the Trust may be significantly changed only with the consent of the
Holders of Investor Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% of the Aggregate Invested Amount. Any such amendment and any such consent by the Class A
Certificateholder, including the deemed consent described in the following sentence, 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 Class A Certificateholder, by
acceptance of this Class A Certificate, will be deemed to have consented for all purposes to any
amendment that any Seller determines is necessary or desirable for such Seller to maintain or
establish sale accounting treatment under then-applicable financial accounting standards.



     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 class of Certificates entitled “Discover Card Master
Trust I, Series 2007-1 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 2007-1 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 2007-1
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 $78,948,000; plus the face amount of any
Class B Certificates issued in an increase of the Series Investor Interest pursuant to Section 31
of the Series Supplement. 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



A-2-4









 







new Series of investor certificates, which will represent Fractional Undivided Interests in
the Trust.



     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
March 2007, or if such 15th day is not a Business Day, on the next succeeding Business Day (each,
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 is
scheduled to be paid in a single payment on the Distribution Date in March 2010 (the “Class B
Expected Final Payment Date”), but may be paid sooner or later or in installments under certain
circumstances. 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 the first Business Day following the Distribution Date in August 2012 (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



A-2-5









 







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
Certificateholder of each affected Class then of record; and, provided, further, that the permitted
activities of the Trust may be significantly changed only with the consent of the Holders of
Investor Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of
the Aggregate Invested Amount. Any such amendment and any such consent by the Class B
Certificateholder, including the deemed consent described in the following sentence, 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 Class B Certificateholder, by
acceptance of this Class B Certificate, will be deemed to have consented for all purposes to any
amendment that any Seller determines is necessary or desirable for such Seller to maintain or

	1	 	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 highest 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(e)),
in assessing the current performance of the Trust and the Receivables. An
amortization event occurs if the three-month rolling average Group, Interchange
Subgroup and Series Excess Spread are all less than zero. 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. Funds remaining after reallocation are distributed to
Discover Bank for its general use in its regular course of business.
	 
	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 series is the
difference between (a) the sum of Finance Charge Collections, Investment Income
and Series Interchange for any Class of this series (see Item 3(c)), and (b)
the sum of (i) the monthly interest for this series (see “Deposits into
the SIFA on this Distribution Date” in Item 6), (ii) the monthly
servicing fee for this series (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 series 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
series 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.
