  The profile vector of a family $\mathcal{F}$ of subsets of an $n$-element set
is $(f_0,f_1, \ldots, f_n)$ where $f_i$ denotes the number of the $i$-element
members of $\mathcal{F}$. In this paper we determine the extreme points of the
set of profile vectors for the class of non-trivial intersecting families.
