  In this paper, we calculate the masses and mixing angles of L=1 negative
parity N* resonances in an extended GBE (Goldstone-boson-exchange model) with
harmonic-oscillator wave functions. By using those mixing angles, we get their
photoproduction amplitudes, and compare them with experimental data and the
results of OPE (one-pion-exchange model), OPsE (only pseudoscalar meson
exchange model), and OGE (one-gluon-exchange model). We find that the extended
GBE gives right internal wave functions. It is essential to extend GBE to
include not only pseudoscalar meson exchanges but also vector meson exchanges.
