The following coupled damped Klein-Gordon-Schrödinger equations are considered
 $\begin{eqnarray*} i\psi_t + \Delta \psi + i \alpha b(x)(|\psi|^{2} + 1)\psi & = & \phi \psi \chi_{\omega} \; \hbox{in}\; \Omega \times (0, \infty), \; (\alpha >0)\ \\ \phi_{tt} - \Delta \phi + a(x) \phi_t & = & |\psi|^2 \chi_{\omega}\; \hbox{in}\; \Omega \times (0, \infty), \end{eqnarray*}$
where
 $\Omega$
is a bounded domain of
 $\mathbb{R}^2$
, with smooth boundary
 $\Gamma$
and
 $\omega$
is a neighbourhood of
 $\partial \Omega$
satisfying the geometric control condition. Here
 $\chi_{\omega}$
represents the characteristic function of
 $\omega$
. Assuming that
 $a, b\in L^{\infty}(\Omega)$
are nonnegative functions such that
 $a(x) \geq a_0 >0$
in
 $\omega$
and
 $b(x) \geq b_{0} > 0$
in
 $\omega$
, the exponential decay rate is proved for every regular solution of the above system. Our result generalizes substantially the previous ones given by Cavalcanti et. al in the reference [9] and [1].
