NOTHING TO REPORT

A class designation of notes determines the relative seniority for receipt of cash flows and funding of uncovered defaults on principal receivables allocated to the related series of notes. The Class B notes are subordinate to the Class A notes and the Class C notes are subordinate to the Class A and Class B notes. With respect to the tranches in each class of notes, the cash flows and funding of uncovered defaults will be allocated to the tranches on a pro rata basis.

Without noteholder consent, BA Credit Card Trust may issue a new series, class or tranche of notes at any time upon the satisfaction of certain conditions described in the underlying transaction agreements, including confirmation that (i) the issuer reasonably believes that the new issuance will not adversely affect the amount of funds available to be distributed to the holders of any outstanding notes or the timing of such distributions, and (ii) the new issuance will not cause a reduction, qualification or withdrawal of the ratings of any outstanding notes.

In addition, without noteholder consent and without the consent of any holders of certificates issued by BA Master Credit Card Trust II, FIA has the right to designate, from time to time, additional eligible credit card accounts to BA Master Credit Card Trust II. In connection with any such designation, FIA will transfer the related receivables, whether then existing or thereafter created, to BA Master Credit Card Trust II.
