DFS Services LLC 

Riverwoods, IL 

We have examinedmanagement’s assertion, included in the accompanying Management’s Assertion on Compliance with Regulation AB Criteria, that DFS Services LLC (DFS) complied with the servicing criteria set forth in Item 1122(d) of the Securities andExchange Commission’s Regulation AB for the Asset-Backed Securities transactions involving credit card receivables conducted by Discover Card Master Trust I and Discover Card Execution Note Trust (the “Platform”) as of and for theyear ended November 30, 2010, excluding the criteria set forth in Items 1122 (d)(1) (i), (d)(1)(iii), (d)(1)(iv), (d)(2)(ii), (d)(2)(iii), (d)(2)(iv), (d)(2)(v), (d)(2)(vi), (d)(2)(vii), (d)(3)(i), (d)(3)(ii), (d)(3)(iii), (d)(3)(iv),(d)(4)(i), (d)(4)(ii), (d)(4)(iii), (d)(4)(v), (d)(4)(x), (d)(4)(xi), (d)(4)(xii), (d)(4)(xiii), and (d)(4)(xv), which management has determined are not applicable to the activities performed by DFS with respect to the Platform. Appendix A tomanagement’s assertion identifies the individual asset backed-transactions defined by management as constituting the Platform. Management is responsible for DFS’ compliance with the servicing criteria. Our responsibility is to express anopinion on management’s assertion about DFS’ compliance with the servicing criteria based on our examination. 

Our examination wasconducted in accordance with attestation standards issued by the American Institute of Certified Public Accountants, as adopted by the Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on a test basis,evidence about DFS’ compliance with the applicable servicing criteria, including tests on a sample basis of the servicing activities related to the Platform, determining whether DFS performed those selected activities in compliance with theservicing criteria during the specified period, and performing such other procedures as we considered necessary in the circumstances. Our procedures were limited to selected servicing activities performed by DFS during the period covered by thisreport and accordingly, such samples may not have included servicing activities related to each asset-backed transaction included in the Platform. Further, an examination is not designed to detect noncompliance arising from errors that may haveoccurred prior to the period specified above that may have affected the balances or amounts calculated or reported by DFS during the period covered by this report. We believe that our examination provides a reasonable basis for our opinion. Ourexamination does not provide a legal determination on DFS’ compliance with the servicing criteria. 

As described in management’sassertion, for servicing criteria 1122(d)(2)(i), 1122(d)(4)(iv), 1122(d)(4)(vii) and 1122(d)(4)(viii), DFS has engaged vendors to perform certain activities required by this servicing criteria. DFS has determined that these vendors are notconsidered a “servicer” as defined in Item 1101(j) of Regulation AB, and DFS has elected to take responsibility for assessing compliance with the servicing criteria applicable to these vendors as permitted by Interpretation 17.06 ofthe SEC Division of Corporation Finance Manual of Publicly Available Telephone Interpretations (Interpretation 17.06). As permitted by Interpretation 17.06, DFS has asserted that it has policies and procedures in place designed to provide reasonableassurance that 

the vendors’ activities comply in all material respects with the servicing criteria applicable to these vendors. DFS is solely responsible for determining that it meets the SEC requirementsto apply Interpretation 17.06 for these vendors and related criteria as described in its assertion, and we performed no procedures with respect to DFS’ determination of its eligibility to use Interpretation 17.06. 

In our opinion, management’s assertion that DFS complied with the aforementioned applicable servicing criteria as of and for the year endedNovember 30, 2010 for the Platform is fairly stated, in all material respects.
