  Let $B(t), t\in \mathbb{R}$ be a standard Brownian motion. In this paper, we
derive the exact asymptotics of the probability of Parisian ruin on infinite
time horizon for the following risk process \begin{align}\label{Rudef}
R_u^{\delta}(t)=e^{\delta t}\left(u+c\int^{t}_{0}e^{-\delta v}d
v-\sigma\int_{0}^{t}e^{-\delta v}d B(v)\right),\quad t\geq0, \end{align} where
$u\geq 0$ is the initial reserve, $\delta\geq0$ is the force of interest, $c>0$
is the rate of premium and $\sigma>0$ is a volatility factor.
  Further, we show the asymptotics of the Parisian ruin time of this risk
process.
