		An “Amortization Event” for each subseries is an event that will cause the trust to begin repaying principal on a monthly basis.

Minimum Monthly Payment Rates		Subseries 1:

		In order to repay the principal of the certificates in full at their applicable expected maturities, the trust will need a minimum monthly payment rate of 9.13% for the Class A, Subseries 1 Certificates and a minimum monthly payment rate of 6.29% for the Class B, Subseries 1 Certificates, assuming (i) an annual yield of 16.39%, (ii) a net charge-off rate of 4.14% per year, (iii) that the Principal Receivables in the trust remain above the Minimum Principal Receivables Balance (described below), (iv) the subseries is not receiving collections or income originally allocated to another series or subseries, (v) no Amortization Event occurs and (vi) the master servicer does not elect to

		delay the commencement of the period during which it allocates collections to repay the principal of the certificates.

		Subseries 2:

		In order to repay the principal of the certificates in full at their applicable expected maturities, the trust will need a minimum monthly payment rate of 9.13% for the Class A, Subseries 2 Certificates and a minimum monthly payment rate of 6.29% for the Class B, Subseries 2 Certificates, assuming (i) an annual yield of 16.39%, (ii) a net charge-off rate of 4.14% per year, (iii) that the Principal Receivables in the trust remain above the Minimum Principal Receivables Balance (described below), (iv) the subseries is not receiving collections or income originally allocated to another series or subseries, (v) no Amortization Event occurs and (vi) the master servicer does not elect to delay the commencement of the period during which it allocates collections to repay the principal of the certificates.

Minimum Principal Receivables Balance		The “Minimum Principal Receivables Balance” is an amount equal to the minimum principal receivables balances for each series, including each subseries, then outstanding. As of April 25, 2007, after giving effect to the issuance of Series 2007-3, the Minimum Principal Receivables Balance for the trust would be $[31,211,649,462.37]. The actual amount of Principal Receivables in the trust as of March 31, 2007 exceeds this amount by $[3,518,351,289.66]. The excess of Principal Receivables over the Minimum Principal Receivables Balance as of such date reflects [10.13]% of the total amount of Principal Receivables in the trust.

		“Principal Receivables” are amounts owing by obligors under accounts that are allocated to the trust, excluding periodic finance charges and other charges and fees. References to “Accounts” in this series term sheet will mean accounts that are allocated to the trust.

Series Termination Date		For each subseries, the Series Termination Date is the last day on which the trust will pay principal on the certificates for that subseries.

		Subseries 1: For Class A, Subseries 1 and Class B, Subseries 1, the Series Termination Date is the first business day following October 15, 2012, or if October 15, 2012 is not a business day, the second business day following October 15, 2012.

		Subseries 2: For Class A, Subseries 2 and Class B, Subseries 2, the Series Termination Date is the first business day following October 15, 2014, or if October 15, 2014 is not a business day, the second business day following October 15, 2014.

This material was not prepared by the Xxxxxx Xxxxxxx research department. Please refer to important information and qualifications at the end of this material.


Subordination of Class B Certificates (Class A Credit Enhancement)		For each subseries, the Class B Certificates are subordinated to the Class A Certificates for that subseries, up to a specified dollar amount, known as the “Available Subordinated Amount.”

Available Subordinated Amount		Subseries 1:
		Initially, equal to 12.5% of the Series Initial Investor Interest for Subseries 1, which may be reduced, reinstated or increased from time to time. The Available Subordinated Amount for Subseries 1 will increase by:

		• 0.5% of the Series Initial Investor Interest for Subseries 1 after a Supplemental Credit Enhancement Event, if Discover Bank has not made an Effective Alternative Credit Support Election for Subseries 1;

		• 4.5% of the Series Initial Investor Interest for Subseries 1 after an Effective Alternative Credit Support Election, if a Supplemental Credit Enhancement Event has occurred for Subseries 1; or

		• 5.0% of the Series Initial Investor Interest for Subseries 1 after an Effective Alternative Credit Support Election, if a Supplemental Credit Enhancement Event has not occurred for Subseries 1.

		The “Series Initial Investor Interest” for Subseries 1 is equal to the total initial principal amount of the Floating Rate Class A, Subseries 1 Certificates plus the total initial principal amount of the Floating Rate Class B, Subseries 1 Certificates. If additional certificates are issued in Subseries 1 after the initial issuance date for Series 2007-3, the “Series Initial Investor Interest” will be deemed to include the initial principal amount of the additional certificates from and after the date of such additional issuance.

		Subseries 2:

		Initially, equal to 12.5% of the Series Initial Investor Interest for Subseries 2, which may be reduced, reinstated or increased from time to time. The Available Subordinated Amount for Subseries 2 will increase by:

		• 0.5% of the Series Initial Investor Interest for Subseries 2 after a Supplemental Credit Enhancement Event, if Discover Bank has not made an Effective Alternative Credit Support Election for Subseries 2;

		• 4.5% of the Series Initial Investor Interest for Subseries 2 after an Effective Alternative Credit Support Election, if a Supplemental Credit Enhancement Event has occurred for Subseries 2; or

		• 5.0% of the Series Initial Investor Interest for Subseries 2 after an Effective Alternative Credit Support Election, if a

This material was not prepared by the Xxxxxx Xxxxxxx research department. Please refer to important information and qualifications at the end of this material.


		Supplemental Credit Enhancement Event has not occurred for Subseries 2.

		The “Series Initial Investor Interest” for Subseries 2 is equal to the total initial principal amount of the Floating Rate Class A, Subseries 2 Certificates plus the total initial principal amount of the Floating Rate Class B, Subseries 2 Certificates. If additional certificates are issued in Subseries 2 after the initial issuance date for Series 2007-3, the “Series Initial Investor Interest” will be deemed to include the initial principal amount of the additional certificates from and after the date of such additional issuance.

		A “Supplemental Credit Enhancement Event” will occur for each subseries the first time Standard & Poor’s Ratings Services withdraws the long-term debt or deposit rating of Discover Bank, or an additional seller, if any, or reduces this rating below BBB-.

		“Effective Alternative Credit Support Election” will mean an effective election made by Discover Bank to change the way in which the trust allocates finance charge collections to Subseries 1 or Subseries 2. To make this election, Discover Bank must arrange for the deposit of additional funds into the cash collateral account for Subseries 1 or Subseries 2, discussed below, as appropriate.

Cash Collateral Account (Class B Credit Enhancement)		Subseries 1:

		Discover Bank will arrange to have a cash collateral account established and funded with an amount equal to 7.5% of the Series Initial Investor Interest for Subseries 1 for the direct benefit of the Class B, Subseries 1 investors, the “Credit Enhancement Account,” for Subseries 1 on the date the certificates are issued. The trustee may withdraw funds from this account to reimburse the Class B, Subseries 1 investors for amounts that would otherwise reduce their interest in the trust or affect their interest payments.

		The amount on deposit in this account may decrease or increase on future Distribution Dates. A “Distribution Date” is the 15th calendar day of each month, or the next business day, beginning for this subseries in June 2007.

		The maximum amount of Credit Enhancement for Subseries 1 as of any Distribution Date will be:

		Before a Supplemental Credit Enhancement Event or an Effective Alternative Credit Support Election

		• 7.5% of the Series Investor Interest for Subseries 1 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 1; or

		After a Supplemental Credit Enhancement Event but before an Effective Alternative Credit Support Election

This material was not prepared by the Xxxxxx Xxxxxxx research department. Please refer to important information and qualifications at the end of this material.


		• 8.0% of the Series Investor Interest for Subseries 1 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 1; or

		After an Effective Alternative Credit Support Election

		• 12.5% of the Series Investor Interest for Subseries 1 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 1.

		However, if an Amortization Event for Subseries 1 has occurred, the maximum amount of Credit Enhancement will be the amount on deposit in the Credit Enhancement Account for Subseries 1 on the Distribution Date immediately before the Amortization Event occurred.

		“Series Investor Interest” with respect to Subseries 1 will mean the Series Initial Investor Interest for Subseries 1 minus

		• the amount of principal collections on deposit for the benefit of investors in Subseries 1,

		• the amount of losses of principal on investments of principal collections on deposit for the benefit of investors in Subseries 1,

		• the aggregate amount of principal previously paid to investors in Subseries 1, and

		• the aggregate amount of investor losses attributable to Subseries 1 resulting from accounts in which the receivables have been charged-off as uncollectible, after giving effect to all provisions in the Series Supplement to reimburse these charged-off amounts.

		Subseries 2:

		Discover Bank will arrange to have a cash collateral account established and funded with an amount equal to 7.5% of the Series Initial Investor Interest for Subseries 2 for the direct benefit of the Class B, Subseries 2 investors, the “Credit Enhancement Account,” for Subseries 2 on the date the certificates are issued. The trustee may withdraw funds from this account to reimburse the Class B, Subseries 2 investors for amounts that would otherwise reduce their interest in the trust or affect their interest payments.

		The amount on deposit in this account may decrease or increase on future Distribution Dates. A “Distribution Date” is the 15th calendar day of each month, or the next business day, beginning for this subseries in June 2007.

		The maximum amount of Credit Enhancement for Subseries 2 as of any Distribution Date will be:

		Before a Supplemental Credit Enhancement Event or an Effective Alternative Credit Support Election

		• 7.5% of the Series Investor Interest for Subseries 2 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 2; or

		After a Supplemental Credit Enhancement Event but before an Effective Alternative Credit Support Election

		• 8.0% of the Series Investor Interest for Subseries 2 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 2; or

		After an Effective Alternative Credit Support Election

		• 12.5% of the Series Investor Interest for Subseries 2 as of the end of the preceding month, but not less than 1% of the Series Initial Investor Interest for Subseries 2.

		However, if an Amortization Event for Subseries 2 has occurred, the maximum amount of Credit Enhancement will be the amount on deposit in the Credit Enhancement Account for Subseries 2 on the Distribution Date immediately before the Amortization Event occurred.

		“Series Investor Interest” with respect to Subseries 2 will mean the Series Initial Investor Interest for Subseries 2 minus

		• the amount of principal collections on deposit for the benefit of investors in Subseries 2,

		• the amount of losses of principal on investments of principal collections on deposit for the benefit of investors in Subseries 2,

		• the aggregate amount of principal previously paid to investors in Subseries 2, and

		• the aggregate amount of investor losses attributable to Subseries 2 resulting from accounts in which the receivables have been charged-off as uncollectible, after giving effect to all provisions in the Series Supplement to reimburse these charged-off amounts.

The Receivables		The receivables in the Accounts included in the trust as of March 31, 2007 totaled $35,167,231,501.38.

Interchange		Subseries 1 and Subseries 2 will each be eligible for allocations and reallocations of interchange. Series issued prior to November 3, 2004 will not receive allocations or reallocations of interchange.

Group Excess Spread and Interchange Subgroup Excess Spread		The certificates of each subseries (which are treated as a “series”) initially will be included in the “Group One” group of

		series. The three-month rolling average Group Excess Spread Percentage, as defined below, was 4.84% for the Distribution Date in April 2007. The Group Excess Spread Percentage excludes the effects of interchange. The three-month rolling average Interchange Subgroup Excess Spread, as defined below, as an annualized percentage of the Series Investor Interest for all series entitled to interchange, was 7.87% for the Distribution Date in April 2007.

		“Series Excess Spread” for a series or subseries is generally an amount equal to

		• the total amount of finance charge collections, investment income, interchange and other similar collections allocable to such series or subseries for the prior calendar month, minus

		• the total amount of interest and certain fees payable for such series or subseries and the amount of receivables allocable to such series or subseries that have been charged off as uncollectible for the prior calendar month.

		“Group Excess Spread” for any Distribution Date is the sum of the Series Excess Spreads (modified as discussed below) for all series, including each subseries, in Group One. “Group Excess Spread Percentage” for any Distribution Date is a percentage calculated by multiplying:

		• twelve, by

		• the sum of the Series Excess Spreads (modified as discussed below) for all series, including each subseries, in Group One,

		and then dividing the product by an amount equal to the sum of all investor interests for each series or subseries in Group One, in each case for the Distribution Date. For purposes of determining the Group Excess Spread and the Group Excess Spread Percentage, we will subtract interchange from the Series Excess Spread for each series or subseries that otherwise has positive Series Excess Spread. However, if this subtraction would cause the Series Excess Spread to be negative, Series Excess Spread for such series or subseries will be deemed to be zero.

		“Interchange Subgroup Excess Spread” for any Distribution Date means the sum of:

		• all amounts deposited in the Group Interchange Reallocation Account for all series or subseries to which interchange is allocated, and

		• the Interchange Subgroup Allocable Group Excess Spread;

This material was not prepared by the Xxxxxx Xxxxxxx research department. Please refer to important information and qualifications at the end of this material.


		where “Interchange Subgroup Allocable Group Excess Spread” means, for any Distribution Date:

		• if the Group Excess Spread is positive or zero, an amount equal to the Group Excess Spread multiplied by the sum of the investor interests for each series or subseries in Group One to which interchange is allocated, divided by

		• an amount equal to the sum of all investor interests for each series or subseries in Group One;

		and

		• if the Group Excess Spread is negative, an amount equal to the Group Excess Spread multiplied by the sum of the Series Excess Spreads for each series or subseries in Group One to which interchange is allocated and for which the Series Excess Spread was negative, divided by

		• an amount equal to the sum of the Series Excess Spreads for each series or subseries in Group One for which the Series Excess Spread was negative.

Rating of the Investor Certificates		The trust will only issue the certificates if Standard & Poor’s has rated the Class A Certificates for each subseries “AAA” and the Class B Certificates for each subseries at least “A” and Xxxxx’x Investors Service, Inc. has rated the Class A Certificates for each subseries “Aaa” and has rated the Class B Certificates for each subseries at least “A2.”

ERISA Considerations		Discover Bank believes that employee benefit plans subject to ERISA may acquire Class A Certificates for any subseries; however, advisers to these plans should consult their own counsel. Employee benefit plans subject to ERISA and entities whose assets are considered to be assets of an employee benefit plan subject to ERISA may not acquire the Class B Certificates for any subseries.

Underwriting		It is anticipated that the underwriters named below will purchase from Discover Bank, as an allocation of the Class A, Subseries 1 and Subseries 2 Certificates and Class B, Subseries 1 and Subseries 2 Certificates, the respective percentages set forth opposite their names less underwriting discounts and commissions:

		Class B, Subseries 1 and Subseries 2 Certificates are expected to be [___]%. Each underwriter has advised Discover Bank that it expects the concession it offers certain dealers to be up to 60% of such discounts and commissions, and the underwriters may allow, and these dealers may reallow, a concession of up to 30% of such discounts and commissions to certain other dealers.

Listing		Discover Bank expects to list the certificates on the Official List of the Luxembourg Stock Exchange and to trade the certificates on the Euro MTF Market of the Luxembourg Stock Exchange, in accordance with the rules of the Luxembourg Stock Exchange, to facilitate trading in non-U.S. markets.

Summary Historical Performance of the Accounts

The information below about the performance of the trust Accounts for historical periods reflects only the performance of Accounts that were designated for the 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 trust Accounts. The performance information included in this section is generally consistent with the type of performance information that will be provided in the monthly certificateholders statement for each subseries.

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 charge collections 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 trust that have been charged off as uncollectible, including the proceeds of charged-off receivables that Discover Bank has removed from the trust, are included in the trust and are treated as Finance Charge Collections. Discover Bank allocates, to the extent applicable for any series, including any subseries, issued on or after November 3, 2004, interchange, 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:


	Three Months
	Ended
	March 31,			Twelve Months Ended December 31,
Aggregate Yields	2007			2006			2005			2004			2003
Finance Charges and Fees (Excluding Recoveries and Interchange)($000)	$	1,447,518		$	5,229,147		$	5,002,729		$	5,323,969		$	5,534,492
Yield Excluding Recoveries and Interchange		16.39	%		16.43	%		15.25	%		15.45	%		15.85	%
Yield Excluding Recoveries and Including Interchange		19.41	%		19.91	%		18.35	%		18.76	%		15.85	%
Gross Yield Including Recoveries and Interchange		20.36	%		20.90	%		19.44	%		19.66	%		16.67	%

After November 30, 2003, when we refer to yield excluding recoveries and interchange, we are excluding only recoveries related to the charge-off of principal, but are including recoveries related to finance charge and fee write-offs. These finance charge and fee recoveries were previously reflected in net charge-offs, but net charge-offs now includes only charge-offs and recoveries of principal. See the chart “Summary Charge-Off Information.” 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 of the table titled “Gross Yield Including Recoveries and Interchange.” The certificates of each subseries of this Series 2007-3 will be eligible to receive allocations and reallocations of interchange received by the trust in accordance with the terms of the series supplement. Other certificates issued after this series, including each subseries, may also be eligible to receive allocations and reallocations of interchange if so provided in their respective series supplements. 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 are 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:


	Three Months
	Ended
	March 31,		Twelve Months Ended December 31,
	2007		2006		2005		2004		2003
Gross Principal Charge-offs ($000)	$	449,714	$	1,507,862	$	2,286,570	$	2,463,519	$	2,742,942
Net Principal Charge-offs ($000)	$	365,863	$	1,192,380	$	1,931,329	$	2,153,434	$	2,456,316
Gross Principal Charge-off Rates		5.09%		4.73%		6.97%		7.15%		7.85%
Net Principal Charge-off Rates		4.14%		3.74%		5.89%		6.25%		7.03%

Prior to December 1, 2003 net charge-offs included recoveries related to finance charge and fee write-offs. After November 30, 2003, we excluded recoveries related to finance charge and fee write-offs from net charge-offs. Net charge-offs reflect only recoveries of principal after November 30, 2003.

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:


	Three Months
	Ended
	March 31,			Twelve Months Ended December 31,
	2007			2006			2005			2004			2003
Lowest Monthly Payment Rate		19.73	%		20.29	%		18.99	%		18.19	%		16.60	%
Highest Monthly Payment Rate		22.52	%		22.87	%		21.33	%		20.07	%		18.96	%
Average Monthly Payment Rate		21.14	%		21.81	%		20.59	%		19.27	%		18.15	%

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.


	Three Months Ended			Twelve Months Ended
	March 31, 2007			December 31, 2006
Minimum Monthly Payment Rate		4.35	%		4.05	%
Full Balance Payment Rate		14.39	%		14.47	%

Balance Reductions. The Accounts in the trust may have balance reductions granted for a number of reasons, including merchandise refunds, returns, and fraudulent charges. As of the three months ended March 31, 2007, the average monthly balance reduction rate for the Accounts in the trust attributable to such returns and cardmember fraud was 0.59%.

COMPOSITION AND HISTORICAL PERFORMANCE
OF THE DISCOVER CARD PORTFOLIO

As of February 28, 2007 the Discover Card portfolio was comprised of 41.9 million Discover Card accounts with approximately 18.3 million active accounts. We have set forth information below about the accounts that comprise the Discover Card portfolio.

Composition and Distribution of the Discover Card Portfolio

Geographic Distribution. The Discover Card portfolio is not highly concentrated geographically. As of February 28, 2007, the following nine states comprised at least 50% of the receivables balances:


	Percentage of Total
State	Receivables
California		9.6	%
Texas		8.5	%
New York		6.8	%
Florida		5.9	%
Illinois		5.5	%
Pennsylvania		4.8	%
Ohio		4.5	%
Michigan		3.7	%
New Jersey		3.6	%
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.

Credit Limit Information. As of February 28, 2007, the accounts in the Discover Card portfolio had the following credit limits:


	Receivables		Percentage					Percentage
	Outstanding		of Total			Number of		of Total
Credit Limit	($000’s)		Receivables			Accounts		Accounts
