The master trust paid all other series of certificates on time in accordance with their expected principal payment schedules, indices, or expected maturity dates, as applicable.
Seller/Sponsor/Depositor	Discover Bank.
Master Servicer/Servicer/Calculation Agent	Discover Bank.
Master Trust Trustee and Indenture Trustee	U.S. Bank National Association will act as trustee, paying agent and registrar under the pooling and servicing agreement and as indenture trustee under the indenture. U.S. Bank National Association is a national banking association and a wholly-owned subsidiary of U.S. Bancorp, which was, as of March 31, 2008, ranked as the 6th largest bank holding company in the United States with total assets exceeding $242 billion as of March 31, 2008. As of March 31, 2008, U.S. Bancorp served approximately 14.9 million customers, operated 2,522 branch offices in 24 states and had over 50,000 employees. U.S. Bank has one of the largest corporate trust businesses in the country with offices in 46 U.S. cities. The pooling and servicing

2

	agreement and the indenture will be administered from U.S. Bank’s corporate trust office located at 209 South LaSalle Street, Chicago, Illinois 60604. U.S. Bank has provided corporate trust services since 1924. As of March 31, 2008, U.S. Bank was acting as trustee with respect to over 82,000 issuances of securities with an aggregate outstanding principal balance of over $2.4 trillion. This portfolio includes corporate and municipal bonds, mortgage-backed and asset-backed securities and collateralized debt obligations. As of March 31, 2008, U.S. Bank National Association (and its affiliate U.S. Bank Trust National Association) was acting as trustee (or indenture trustee), paying agent and registrar on 70 issuances of credit card receivables-backed securities with an outstanding aggregate principal balance of approximately $33,272,000,000.
Owner Trustee for the Note Issuance Trust	Wilmington Trust Company.
Time of Sale	The time of sale is expected to be at or around [Ÿ] [a.m./p.m.] New York City time on June [11], 2008, the time at which the Underwriting Agreement and Terms Agreement for the Class A(2008-4) notes are expected to be executed among Discover Bank, Discover Card Execution Note Trust and the underwriters for the Class A(2008-4) notes and commitments to purchase notes are expected first to be made.
Initial Principal Amount	$[500,000,000].
Initial Nominal Liquidation Amount	$[500,000,000].
Interest Rate	[Ÿ]% per year.
	Interest will be calculated on the Outstanding Dollar Principal Amount of the notes for the period from and including the preceding interest payment date (or for the first interest payment date, from and including the issuance date of the notes and assuming the month in which the notes are issued has 30 days) to and excluding the current interest payment date on the basis of a 360-day year of twelve 30-day months.
Interest Payment Dates	The 15th day of each month, or the next business day, beginning in July 2008. The note issuance trust will pay your interest on each interest payment date from the funds on deposit in the interest funding subaccount for your tranche on that date.
Expected Maturity Date	June 17, 2013 or the next business day. The note issuance trust expects to pay the Stated Principal Amount of the Class A(2008-4) notes in one payment on their expected maturity date, and is obligated to do so if funds are available for that purpose. If the Stated Principal Amount of the Class A(2008-4) notes is not paid in full on the expected maturity date due to insufficient funds, noteholders will generally not have any remedies against the note issuance trust until the legal maturity date of the Class A(2008-4) notes. If an early redemption event or an event of default occurs, the note issuance trust will pay principal monthly and the final principal payment may be made before or after June 17, 2013.
Average Life	Assuming (i) closing occurs on June [18], 2008, (ii) no early redemption event or event of default occurs and (iii) payment will be made in full on the expected maturity date and adjusting for

3

	weekends and holidays, the average life is expected to be [5.00] years. The average life calculation for the notes is based on a 360-day year of twelve 30-day months.
Legal Maturity Date	The distribution date in December 2015. If the note issuance trust owes principal on the legal maturity date, it will cause the master trust to sell receivables up to this tranche’s remaining Nominal Liquidation Amount plus accrued and unpaid interest to repay the Class A(2008-4) notes. On and after the legal maturity date, the investor interest in receivables represented by the collateral certificate will no longer reflect the Nominal Liquidation Amount of this tranche, the master trust will not allocate collections or interchange to the collateral certificate based on the Nominal Liquidation Amount of this tranche, and the note issuance trust will not allocate Series Finance Charge Amounts or Series Principal Amounts to this tranche.
Expected Issuance Date	June [18], 2008.
Cut-off Date	June 1, 2008. The cut-off date is the date from which collections on the master trust’s receivables are allocated to the collateral certificate in an increased amount reflecting the issuance of these Class A(2008-4) notes.
Accumulation Period	The note issuance trust will begin to accumulate cash in the principal funding subaccount for these Class A(2008-4) notes on July 15, 2012, or the next business day, using collections it receives on or after June 1, 2012, to pay principal at the expected maturity date, unless (i) this process is delayed by the calculation agent on behalf of the note issuance trust, (ii) the note issuance trust has already prefunded the principal funding subaccount for these Class A(2008-4) notes following the expected maturity date of a subordinated tranche of notes or (iii) an early redemption event or an event of default has occurred. See “Deposits and Allocation of Funds for DiscoverSeries Notes — Prefunding” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes. The calculation agent may not delay the commencement of the accumulation period beyond the first day of the month immediately prior to the month in which the expected maturity date occurs. The note issuance trust will be scheduled to accumulate Series Principal Amounts and similar amounts reallocated from other series of master trust certificates and other series of notes in the principal funding subaccount for these Class A(2008-4) notes over several months, so that it will have collections available to make the final payment.
	The calculation agent on behalf of the note issuance trust is required to shorten the accumulation period for these notes only if the calculation agent determines in good faith that certain conditions will be satisfied, including the following:
	•        the calculation agent reasonably believes, based on the payment rate and the anticipated availability of Series Principal Amounts and similar amounts reallocated from other series of master trust certificates and other series of notes, that delaying the start of the accumulation period for this tranche of notes will not result in failure to make full payment of any tranche of notes on its expected maturity date, and

4

	•        the applicable note rating agencies confirm that shortening the accumulation period for this tranche of notes will not cause a reduction or qualification with negative implications of the ratings of any outstanding tranche of DiscoverSeries notes rated by such Note Rating Agency, in each case below the required ratings (after giving effect to such negative implications), or a withdrawal of any such ratings.
	Series Principal Amounts allocable to the Class A(2008-4) notes will be applied to tranches of DiscoverSeries notes which are accumulating or prefunding principal, based on seniority; deposited in the master trust’s Principal Collections reallocation account to pay principal of other series of master trust certificates or other series of notes; or deposited in the master trust collections account for reinvestment in the collateral certificate.
Receivables	The receivables in the master trust as of May 31, 2008, totaled $38,144,549,720.85.
Minimum Principal Receivables Balance	After giving effect to all prior issuances but excluding the issuance of these Class A(2008-4) notes and the corresponding increase in the investor interest in receivables represented by the Series 2007-CC collateral certificate, the Minimum Principal Receivables Balance for the master trust as of June 10, 2008, would be $29,028,983,870.97. The actual amount of Principal Receivables in the master trust as of May 31, 2008, was $37,666,723,623.48, which exceeds this Minimum Principal Receivables Balance by $8,637,739,752.51. The excess of Principal Receivables as of May 31, 2008 over this Minimum Principal Receivables Balance as of June 10, 2008, reflects 22.93% of the total amount of Principal Receivables in the master trust. The Minimum Principal Receivables Balance is the amount of Principal Receivables the master trust is required to hold under its Pooling and Servicing Agreement to support all outstanding master trust certificates. The amount of any new issuance of notes, including the issuance of these Class A(2008-4) notes, will increase the Minimum Principal Receivables Balance and will reduce the excess of Principal Receivables over the Minimum Principal Receivables Balance by an amount equal to the face amount of such notes divided by 0.93.
Discover Card Portfolio	As of February 29, 2008, there were approximately 40.2 million Discover Card accounts with approximately 18.2 million active accounts. The total receivables balance in the Discover Card portfolio as of February 29, 2008, November 30, 2007, November 30, 2006 and November 30, 2005 was $46,679,279,000, $47,673,763,000, $45,615,756,000 and $44,241,675,000, respectively.
	The receivables in the accounts designated for the master trust totaled $38,144,549,720.85 and the total number of those accounts was 31,206,885 as of May 31, 2008. Also, as of May 31, 2008, the average account balance was $2,571 (using 14,839,305 active accounts for which cardmembers had a balance, a monetary transaction, or authorization within the past month) and the average credit limit was $8,924.

5

Subordination of Class B and Class C Notes (Class A Credit Enhancement)	These Class A(2008-4) notes receive credit enhancement through the subordination of interest and principal payments on Class B notes and Class C notes and through loss protection provided by such notes. The amount of subordination available to provide credit enhancement to any tranche of notes is limited by its available subordinated amount of each class of notes that is subordinated to it. Each senior tranche of notes has access to credit enhancement from those subordinated notes only in an amount not exceeding its required subordinated amount minus the amount of usage of that required subordinated amount. When we refer to “usage of the required subordinated amount,” we refer to the amount by which the Nominal Liquidation Amount of subordinated notes providing credit enhancement to that tranche of senior notes has declined as a result of losses relating to charged-off receivables and the application of subordinated notes’ principal allocation to pay interest on senior classes and servicing fees.
Required Subordinated Percentage of Class B Notes	Initially, 6.285714%. The note issuance trust may change the required subordinated percentage of Class B notes for your tranche from time to time. However, each applicable Note Rating Agency must confirm that the change will not cause a reduction or qualification with negative implications of the ratings of any outstanding tranche of DiscoverSeries notes rated by such Note Rating Agency, in each case below the required ratings (after giving effect to such negative implications), or a withdrawal of any such ratings.
Required Subordinated Amount of Class B Notes	The Required Subordinated Amount of Class B Notes is determined by multiplying the required subordinated percentage of Class B notes by the Nominal Liquidation Amount of the Class A(2008-4) notes.
Required Subordinated Percentage of Class C Notes	Initially, 8.000000%. The required subordinated percentage of Class C notes for these Class A(2008-4) notes is currently intended to ensure that the amount of Class C notes providing loss protection to these Class A(2008-4) notes equals the amount of Class C notes providing loss protection to the Class A notes by which they are encumbered at any time. The note issuance trust may change the required subordinated percentage of Class C notes for your tranche from time to time. However, each applicable Note Rating Agency must confirm that the change will not cause a reduction or qualification with negative implications of the ratings of any outstanding tranche of DiscoverSeries notes rated by such Note Rating Agency, in each case below the required ratings (after giving effect to such negative implications), or a withdrawal of any such ratings.
Required Subordinated Amount of Class C Notes	The Required Subordinated Amount of Class C Notes is determined by multiplying the required subordinated percentage of Class C notes by the Nominal Liquidation Amount of the Class A(2008-4) notes.
Excess Spread Percentage	The three-month rolling average Excess Spread Percentage, as defined below, was 8.27% for the distribution date in May 2008, without giving effect to the issuance of notes after April 30, 2008, including the anticipated issuance of these Class A(2008-4) notes.

6

	The Excess Spread Amount for the DiscoverSeries for any month is the difference, whether positive or negative, between
	(x)    the sum of (a) the amount of Finance Charge Amounts allocated to the DiscoverSeries pursuant to the Indenture; (b) any amounts to be treated as Series Finance Charge Amounts and designated to be a part of the Excess Spread Amount pursuant to any terms document; (c) an amount equal to income earned on all funds on deposit in the principal funding account (including all subaccounts of such account) (net of investment expenses and losses); and (d) the amount withdrawn from the accumulation reserve subaccount to cover the accumulation negative spread on the principal funding subaccounts, and
	(y)    the sum of all interest, swap payments or accreted discount and servicing fees for the DiscoverSeries notes and reimbursement of all charged-off receivables allocated to the DiscoverSeries, in each case for the applicable period only.
	The Excess Spread Percentage for the DiscoverSeries is equal to the Excess Spread Amount multiplied by twelve and divided by the sum of the Nominal Liquidation Amounts of all outstanding tranches of DiscoverSeries notes.
Group Excess Spread Percentage and Interchange Subgroup Excess Spread Percentage	For the distribution date in May 2008, the three-month rolling average Group Excess Spread Percentage for the master trust was 5.90%, without giving effect to the issuance of notes after April 30, 2008, including the anticipated issuance of these Class A(2008-4) notes. For the distribution date in May 2008, the three-month average Interchange Subgroup Excess Spread Percentage was 9.02%, without giving effect to the issuance of notes after April 30, 2008, including the anticipated issuance of these Class A(2008-4) notes.
	The Group Excess Spread Percentage and the Interchange Subgroup Excess Spread Percentage are each measures of the performance of the master trust. The Group Excess Spread Percentage is generally based on receivables yield minus interest expense, servicing fees, charged-off receivables and credit enhancement fees for all series of master trust certificates (including, for the Series 2007-CC collateral certificate, any such amounts with respect to the notes), and the Interchange Subgroup Excess Spread Percentage also considers the effects of interchange on the series of master trust certificates that receive interchange allocations.
Security for the Notes	The indenture trustee has a security interest, for the benefit of the holders of these Class A(2008-4) notes and the holders of other DiscoverSeries notes, in the collateral certificate, the note issuance trust’s collections, funding and reserve accounts and rights under and proceeds of those assets.
	However, the Class A(2008-4) notes are entitled to the benefits of only that portion of those assets allocated to them under the indenture, the DiscoverSeries indenture supplement and the related terms document.

7

Limited Recourse to DCENT, Early Redemption Events, Events of Default, Excess Spread Early Redemption Cure and Cleanup Call	As set forth in the prospectus supplement for the Class A(2008-3) DiscoverSeries notes.
Accumulation Reserve Account	The note issuance trust will establish an accumulation reserve subaccount to cover shortfalls in investment earnings on amounts, other than prefunded amounts, on deposit in the principal funding subaccount for these Class A(2008-4) notes. Initially, the accumulation reserve account will not be funded.
Required Ratings	The note issuance trust will issue these Class A(2008-4) notes only if they are rated by at least one of the following nationally recognized rating agencies as follows:
	Moody’s Investors Service, Inc.: Standard & Poor’s Ratings Services: Fitch, Inc.:	Aaa AAA AAA
ERISA Eligibility	Subject to important considerations described under “ERISA Considerations” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes, these Class A(2008-4) notes may be purchased by employee benefit plans, individual retirement accounts and persons investing assets of employee benefit plans subject to Title I of ERISA. By purchasing the notes, each investor purchasing on behalf of employee benefit plans or individual retirement accounts will be deemed to certify that the purchase and subsequent holding of the notes by the investor is exempt from the prohibited transaction rules of ERISA and/or Section 4975 of the Internal Revenue Code. See “ERISA Considerations” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes. Advisors to employee benefit plans should consult their own counsel.
Tax Treatment	Subject to important considerations and limitations described under “U.S. Federal Income Tax Consequences” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes, Latham & Watkins LLP, as tax counsel to DCENT, is of the opinion that under existing law these Class A(2008-4) notes will be characterized as debt for federal income tax purposes, and that DCENT will not be classified as an association or publicly traded partnership taxable as a corporation for federal income tax purposes. By accepting a Class A(2008-4) note, you will agree to treat your Class A(2008-4) note as debt for federal, state and local income and franchise tax purposes. See “U.S. Federal Income Tax Consequences” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes for additional information concerning the application of federal income tax laws.

Each underwriter has advised Discover Bank that it expects the concession it offers certain dealers to be up to [0.15]% of such discounts and commissions, and the underwriters may allow, and these dealers may reallow, a concession of up to [0.075]% of such discounts and commissions to certain other dealers. Additional offering expenses are estimated to be $[700,000]. The underwriters have not advised Discover Bank that they intend to retain any portion of the Class A(2008-4) notes for their own account.
Stock Exchange Listing	The note issuance trust will apply to list these Class A(2008-4) notes on the Irish Stock Exchange. We cannot assure you that the application for the listing will be accepted or that, if accepted, such listing will be maintained.
Recent Legislative and Regulatory Initiatives	Members of Congress have held hearings on certain practices in the credit card industry, including those relating to interest rates, fees, grace periods and the two-cycle billing method. It is not clear at this time whether new laws imposing limitations on these credit card practices will be adopted by Congress, or at the state level. In addition, the Federal Reserve Board has proposed amendments to Regulations Z (Truth in Lending) and AA (Unfair or Deceptive Acts or Practices) that, among other things, place limitations on certain credit card practices, including those relating to interest rates, fees, payment allocations, grace periods and the two-cycle billing method. The comment periods for the proposed amendments expire in July 2008 (Regulation Z) and August 2008 (Regulation AA). Any new laws or regulations impacting credit card practices could materially adversely affect the master trust’s performance and Discover Bank.
	The laws governing bankruptcy and debtor relief could also change, making it more expensive or more difficult for Discover Bank to collect from cardmembers. Also, Congress may move to regulate holding companies that own depository institutions, such as Discover Bank, which could result in additional complexity and expense. Furthermore, various federal and state agencies and standard-setting bodies may, from time to time, enact new or amend existing accounting rules or standards that could impact the master trust’s performance or Discover Bank’s capital or capital requirements. See “Risk Factors - Potential Changes Relating to Financial Accounting Standards” in the prospectus accompanying the prospectus supplement for the Class A(2008-3) DiscoverSeries notes.

Current Composition and Distribution of the Master Trust Accounts

We have set forth information below about the accounts that are designated for the master trust. The performance information included in this section is generally consistent with the monthly performance information that will be provided in the monthly certificateholders’ statement for the collateral certificate.

Geographic Distribution. As of May 31, 2008, the following 9 states had the largest receivables balances and comprised over 50% of the receivables:

State	Percentage of Total Receivables
California	9.7	%
Texas	8.3	%
New York	6.6	%
Florida	6.1	%
Illinois	5.6	%
Pennsylvania	4.9	%
Ohio	4.6	%
Michigan	3.6	%
New Jersey	3.5	%
Other States	47.1	%
Total	100.0	%

Since the largest amounts of outstanding receivables were with cardholders whose billing addresses were in California, Texas, New York, Florida, Illinois, Pennsylvania, Ohio, Michigan and New Jersey, adverse changes in the business or economic conditions in these states could have an adverse effect on the performance of the receivables.

Summary Historical Performance of the Accounts

The information below about the performance of the accounts for historical periods reflects only the performance of accounts that were designated for the master trust during the specified time period and has not been restated to reflect the performance of accounts added after such time period. Accordingly, such information does not fully reflect the historical performance of the accounts currently comprising the accounts. The presentation of the information below reflects the treatment of collections and charged-off receivables under the Pooling and Servicing Agreement. The performance information included in this section is generally consistent with the type of performance information that will be provided in the monthly certificateholder’s statement for the collateral certificate.

Summary Yield Information. The annualized monthly yield for the accounts is calculated by dividing the monthly finance charges by beginning monthly Principal Receivables multiplied by twelve. Monthly finance charges include periodic finance charges, cash advance item charges, late fees, overlimit fees and other fees, all net of write-offs. Recoveries received with respect to receivables in the master trust that have been charged off as uncollectible, including the proceeds of charged-off receivables that Discover Bank has removed from the master trust, are included in the master trust and are treated as Finance Charge Collections. Discover Bank allocates, to the extent applicable for any master trust series issued on or after November 3, 2004, interchange to the master trust, which is treated similarly to finance charges. The aggregate yield is the average of the monthly annualized yields for each period shown. The aggregate yield for the accounts is summarized as follows:

12

Aggregate Yields	Four Months Ended April 30,			Twelve Months Ended December 31,
	2008			2007			2006			2005			2004
Finance Charges and Fees (Excluding Recoveries and Interchange) ($000)	$	2,064,379		$	5,903,756		$	5,229,147		$	5,002,729		$	5,323,969
Yield Excluding Recoveries and Interchange		16.29	%		16.40	%		16.43	%		15.25	%		15.45	%
Yield Excluding Recoveries and Including Interchange		19.38	%		19.78	%		19.91	%		18.35	%		18.76	%
Gross Yield Including Recoveries and Interchange		20.30	%		20.69	%		20.90	%		19.44	%		19.66	%
For purposes of the Pooling and Servicing Agreement, all recoveries of principal as well as recoveries of finance charges and fees are treated as Finance Charge Collections, and are reflected in percentages set forth in the row entitled “Gross Yield Including Recoveries and Interchange.” The Series 2007-CC collateral certificate is eligible to receive allocations and reallocations of interchange received by the master trust in accordance with the terms of the series supplement. A portion of such interchange will be available to these Class A(2008-4) notes in accordance with the indenture and the indenture supplement for the DiscoverSeries. Other master trust certificates issued after Series 2007-CC may also be eligible to receive allocations and reallocations of interchange if so provided in their respective series supplements. Master trust certificates issued prior to November 3, 2004 receive no allocations or reallocations of interchange; therefore, interchange is only reflected in the yields above beginning November 2004. Summary Charge-off Information. The annualized monthly charge-off rates for the accounts calculated by dividing the monthly principal charge-offs by beginning monthly Principal Receivables multiplied by twelve. The aggregate charge-off percentages expressed below are the average of the annualized monthly charge-off rates for each period shown. The accounts have had the following aggregate charge-off amounts and aggregate charge-off percentages:
	Four Months Ended April 30,			Twelve Months Ended December 31,
	2008			2007			2006			2005			2004
Gross Principal Charge-offs ($000)	$	744,960		$	1,836,458		$	1,507,862		$	2,286,570		$	2,463,519
Net Principal Charge-offs ($000)	$	628,413		$	1,508,773		$	1,192,380		$	1,931,329		$	2,153,434
Gross Principal Charge-off Rates		5.88	%		5.10	%		4.73	%		6.97	%		7.15	%
Net Principal Charge-off Rates		4.96	%		4.19	%		3.74	%		5.89	%		6.25	%
Summary Payment Rate Information. The monthly payment rate for the accounts is calculated by dividing monthly collections by the receivables in the accounts as of the beginning of the month. The average monthly payment rate for each period shown is calculated by dividing the sum of individual monthly payment rates by the number of months in the period. The accounts have had the following historical monthly payment rates:
	Four Months Ended April 30,			Twelve Months Ended December 31,
	2008			2007			2006			2005			2004
Lowest Monthly Payment Rate		19.25	%		19.73	%		20.29	%		18.99	%		18.19	%
Highest Monthly Payment Rate		21.46	%		22.52	%		22.87	%		21.33	%		20.07	%
Average Monthly Payment Rate		20.33	%		20.93	%		21.81	%		20.59	%		19.27	%

13

Minimum Monthly Payment and Full Balance Payment Rates. Discover Bank calculates the monthly rate of cardmembers that made only the contractual monthly minimum payment due as a percentage of the total accounts as of the beginning of the month. Discover Bank calculates the monthly rate of cardmembers that paid their full balance due as a percentage of the total accounts as of the beginning of the month. The rates below are the average of monthly rates for the period shown.

	Five Months Ended May 31, 2008		Twelve Months Ended December 31, 2007
Minimum Monthly Payment Rate	4.49	%	4.32	%
Full Balance Payment Rate	14.99	%	14.50	%

Balance Reductions. The accounts designated for the master trust may have balance reductions granted for a number of reasons, including merchandise refunds, returns, and fraudulent charges. As of the five months ended May 31, 2008, the average monthly balance reduction rate for the accounts designated for the master trust attributable to such returns and cardmember fraud was 0.57%.
