  A multi-Higgs model with an extra neutral gauge boson ($Z'$) is introduced.
One scalar Higgs boson ($H_2$) in this model decays dominantly into a photon
pair. The $Z'$ decay to $\mu^+\mu^-$ gets a much larger branching ratio than
the $Z$ decay to this channel. The $Z Z' H_2$ vertex provides a final state
from $Z$ decay resembling the new $l^+l^-\gamma\gamma$ events at the LEP. Other
promising phenomenology, such as $Z \rightarrow l\bar l Z'$ is also discussed.
