In this paper, we use asymptotic techniques and the finite difference method to study the spectrum of differential operator arising in exponential stabilization of non-uniform Euler-Bernoulli beam with indefinite damping that is clamped at one end and is free at the other. We build a numerical scheme and investigate the eigenvalues locus as a function of the positive feedback parameters $\alpha$, $\beta$ and the damping coefficient $\gamma$.
