  An inflationary scenario driven by a slow rolling homogeneous scalar field
whose potential $V(\Phi)$ is given by a generalized exponential function is
discussed. Within the {\sl slow-roll} approximation we investigate some of the
main predictions of the model and compare them with current data from Cosmic
Microwave Background and Large-Scale Structure observations. In particular, we
show that this single scalar field model admits a wider range of solutions than
do conventional exponential scenarios and predicts acceptable values of the
scalar spectral index and of the tensor-to-scalar ratio for the remaining
number of {\sl e-folds} lying in the interval $N = 54 \pm 7$ and energy scales
of the order of Planck scale. The running of the spectral index is briefly
discussed to show that both negative and positive values are predicted by the
model here proposed.
