A stochastic bivariate process

is considered. The

are the occurrence times of a random event generated by a Poisson stochastic point process. Each

is the amplitude associated with the

th event at random time

and is constructed from

and the interarrival time

, according to the first-order autoregressive exponential time series model (EAR(l)). Moments and joint distributions for the bivariate process are obtained, as well as the distribution of some extreme values related to the bivariate process.
