  Two qualitatively different modes of ending superluminal expansion are
possible in extended inflation. One mode, different from the one envoked in
most extended models to date, easily avoids making big bubbles that distort the
cosmic microwave background radiation (CMBR). In this mode, the spectrum of
density fluctuations is found to be scale-free, $P(k) \propto k^n$, where $n$
might lie anywhere between 0.5 and 1.0 (whereas, previously, it appeared that
the range $1.0> n \gtsim 0.84$ was disallowed).
