  We construct a general class of exact, regular black hole solutions with
toroidal horizon topology in 5-dimensional AdS gravity with a self-interacting
scalar field. Due to the non-trivial backreaction of the scalar field, the
no-hair theorems can be evaded so that an event horizon can be formed. The
scalar field is regular everywhere outside the curvature singularity and it
vanishes at the boundary where the potential is finite. We study the properties
of these black holes in the context of AdS/CFT duality and comment on the dual
operators, which saturate the unitarity bound. We present exact expressions for
the beta-function and construct a c-function that characterizes the RG flow.
