In this study, second-order nonselfadjoint expression and its associated boundary condition depending on an hyperbolic eigenparameter are discussed. We introduce the sets of eigenvalues and spectral singularities of a boundary value problem (BVP) which is defined with same quantum difference expression and boundary condition. Next, some spectral properties of eigenvalues and spectral singularities are investigated using the Jost solution, green function and resolvent operator of this BVP.
