In this paper we investigate the evolution of a class of cosmologies fuelled by quintom dark energy and dark matter .
Quintom dark energy is a hybrid of quintessence and phantom which involves the participation of two reals scalar fields playing the roles of those two types of dark energy .
In that framework we examine from a dynamical systems perspective the possibility that those fields are coupled among them by considering an exponential potential with an interesting functional dependence similar but not identical to others studied before .
The model we consider represents a counterexample to the typical behavior of quintom models with exponential potentials because it admits either tracking attractors ( w = 0 ) , or phantom attractors ( w < -1 ) .
