This paper deals with the extension of a two band model for Wannier excitons to a model which includes three bands. The interaction of the excitons resulting from any pair of bands is taken into account by diagonalizing a truncated eigenvalue equation. Energy bands and eigenstates of excitons are determined, and the imaginary part of the dielectric function is calculated. For certain choices of parameters, a Fano effect shows up.
