Thereafter, until the Administrator or such Purchaser Agent notifies the Seller that the circumstances giving rise to such suspension no longer exist, (A) no Portion of Capital shall be funded at the Alternate Rate determined by reference to the Euro-Rate or LMIR and (B) the Discount for any outstanding Portions of Capital then funded at the Alternate Rate determined by reference to the Euro-Rate or LMIR shall be converted to the Alternate Rate determined by reference to the Base Rate.

(b)    If, on any day, the Administrator shall have been notified by any Affected Person that such Affected Person has reasonably determined (which determination shall be final and conclusive) that any Change in Law, or compliance by such Affected Person with any Change in Law, shall make it unlawful or impossible for such Affected Person to fund or maintain any Portion of Capital at the Alternate Rate determined by reference to the Euro-Rate or LMIR, the Administrator shall notify the Seller thereof. Upon receipt of such notice, until the Administrator notifies the Seller that the circumstances giving rise to such determination
