WHEREAS, pursuant to Section 13.01 of the Agreement, the Bank and Funding desire to amend the Agreement to include provisions related to measuring the Transferor’s Interest (as defined in the Agreement) for the purposes of Regulation RR (as defined below);

NOW, THEREFORE, in consideration of the premises and agreements contained herein and notwithstanding anything to the contrary set forth in the Agreement, the undersigned parties hereby agree as follows:

ARTICLE I

AMENDMENTS

Section 1.01. Amendments to the Agreement. The Agreement is hereby amended as follows:

(a) Amendment to Section 1.01 of the Pooling and Servicing Agreement. Section 1.01 of the Agreement is hereby amended by adding the following definitions in the appropriate alphabetical order:

“Regulation RR” shall mean Part 244 – Credit Risk Retention (Regulation RR), 12 C.F.R. §§244.1-244.22, as the same may be amended from time to time.

“Seller’s Interest Measurement Date” shall have the meaning specified in Section 13.19.

(b) Amendment to Article XIII of the Pooling and Servicing Agreement. Article XIII of the Pooling and Servicing Agreement is hereby amended by adding the following Section 13.19 in the appropriate numeric order:

Section 13.19 Measuring the Transferor’s Interest for the Purposes of Regulation RR. In order to facilitate Capital One’s obligation to comply with Regulation RR, the Transferor shall, on each Seller’s Interest Measurement Date and on the issuance date of (i) any Investor Certificates hereunder or (ii) any Notes (as defined in the Series 2002-CC Supplement hereto) under the Indenture (as defined in the Series 2002-CC Supplement hereto), measure the Transferor’s Interest in a manner consistent with the requirements of Regulation RR. If on any Seller’s Interest Measurement Date the amount of the Transferor Interest, when measured in a manner consistent with the requirements of Regulation RR, does not satisfy the requirements of Regulation RR, Capital One shall nevertheless be deemed to be in compliance with Regulation RR (as permitted by Regulation RR) so long as the Transferor causes the amount of the Transferor’s Interest, when measured in a manner consistent with the requirements of Regulation RR, to satisfy the requirements of Regulation RR on the immediately subsequent Seller’s Interest Measurement Date and Capital One is otherwise in compliance with Regulation RR as of such date.

For the purposes of this Section 13.19, (i) “Seller’s Interest Measurement Date” shall mean, for so long as any Investor Certificates remain outstanding hereunder or any Notes (as defined in the Series 2002-CC Supplement hereto) remain outstanding under the Indenture (as defined in the Series 2002-CC Supplement hereto), and in each case are held by any Person other than a wholly-owned Affiliate of Capital One (for so long as Capital One acts as sponsor), the close of business on the last Business Day of any Monthly Period, and (ii) the Transferor’s Interest shall constitute a “seller’s interest” for the purposes of Regulation RR.

The terms of this Section 13.19 become effective only on and after the issuance date of (i) any Investor Certificate hereunder or (ii) any Notes (as defined in the Series 2002-CC Supplement hereto) under the Indenture (as defined in any Supplement hereto) occurring on or after the date hereof.

ARTICLE II
