Semantics are given for modal extensions of relevant logics based on the kind of frames introduced in I-7]. By means of a simple recipe we may obtain from a class FRM (L) of unreduced frames characterising a (non-modal) logic L, frame-classes FRM m (L:M) eharacterising conjunctively regular modal ex
