  The possible transition of large mass magnetic monopole solutions to monopole
black hole solutions in Yang-Mills-Higgs theory with spontaneous symmetry
breaking (SSB) coupled to the low energy effective theory of superstring with
only dilatonic sector is studied. Our main motivation is to explore the effects
of the dilaton field on the monopole black hole solutions. Working in the
Einstein conformal gauge, it is explicitly shown, in terms of the Hawking
evaporation of the monopole black hole, that the presence of the dilaton field
appears to introduce a "mass dependent extra attractive interaction" in
addition to that of the standard Einstein gravity into the system.
