*If      the Borrower is split-rated and the ratings differential is one level, the      higher rating will apply. If the Borrower is split-rated and the ratings      differential is two levels or more, the rating level one below the higher level      will apply. If at any time the Borrower has no Moody’s rating or no Standard& Poors’ rating, the “Lower than BBB-/Baa3” level will apply; provided,      however, that in such event the Borrower may propose an alternative rating      agency or mechanism in replacement thereof.*
