WHEREAS, Discover Bank and the Trustee are parties to that certain Second Amended and Restated Pooling and Servicing Agreement, dated as of June 4, 2010, relating to the Discover Card Master Trust I (the “Agreement”); and

WHEREAS, pursuant to Section 13.01(a)(ii) of the Agreement, Discover Bank and the Trustee desire to amend this Agreement, in a manner that shall not adversely affect in any material respects the interests of the Holders of any Class of any Securities currently outstanding or change the permitted activities of the Trust, in order to clarify the authority of Discover Bank, as Servicer, to service Charged-Off Accounts.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements herein contained, each party agrees as follows for the benefit of the other parties and for the benefit of the Certificateholders:

“(i) all payments by or on behalf of an Obligor received by a Servicer in respect of Receivables in the form of cash, checks, wire transfers or other forms of payment in accordance with the relevant Credit Agreement in effect from time to time and all Recovered Amounts, and;”

(b) Effective as of the date hereof, Section 2.03(a) of the Agreement is amended by replacing the reference to “Receivables” in the second sentence with “Receivables (or receivables in Charged-Off Accounts).”

(c) Effective as of the date hereof, Section 2.09(b) of the Agreement is amended by replacing the first sentence with the following:

“Each Seller shall cause the respective Servicer, as its agent, to service and administer the Accounts, the Receivables under which have been transferred to the Trust by such Seller and the receivables in Charged-Off Accounts, which are serviced by such Servicer, in a particular state or similar jurisdiction in accordance with policies identical

to those used in servicing and administering other of such Seller’s credit card accounts in such jurisdiction.”

(d) Effective as of the date hereof, Section 3.01(b) of the Agreement is amended by replacing the reference to “Receivables” in the last sentence with “Receivables (or receivables in Charged-Off Accounts).”

(e) Effective as of the date hereof, Section 3.02 of the Agreement is amended by replacing paragraph (b) with the following paragraph:

“Each Servicer is hereby authorized in the name and on behalf of the Trustee and the Holder of the Seller Certificate, and agrees, to service and administer the Receivables (and receivables in Charged-Off Accounts) with respect to which it is acting as Servicer, and collect payments due under such Receivables (or amounts recovered from receivables in Charged-Off Accounts) in accordance with its customary and usual servicing procedures for servicing credit receivables comparable to the Receivables (or such receivables in Charged-Off Accounts) and in accordance with its Credit Guidelines, and acting alone or through any party designated by it pursuant to Section 8.06, shall do any and all things in connection with such servicing and administration that it may deem necessary or desirable. Without limiting the generality of the foregoing and subject to Section 10.02, each Servicer is hereby authorized and empowered (i) to execute and deliver, on behalf of the Trust for the benefit of the Certificateholders but in its own name, without reference to the fact that it is acting for the Trust, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Receivables (or receivables in Charged-Off Accounts) with respect to which it is acting as Servicer, (ii) after the delinquency of any such Receivable (or receivable in a Charged-Off Account) and to the extent permitted under and in compliance with applicable law and regulations, to commence collection proceedings with respect to such Receivables (or receivables in Charged-Off Accounts) on behalf of the Trust for the benefit of the Certificateholders but in its own name, without reference to the fact that it is acting for the Trust and (iii) subject to Section 3.02(e), to sell the receivables in any Charged-Off Account. The Trustee shall furnish each Servicer with any powers of attorney and other documents necessary or appropriate under the laws of any jurisdiction with authority over the Receivables (or receivables in Charged-Off Accounts) to enable such Servicer to carry out its servicing and administrative duties hereunder.”
