SN 2002ic is a unique supernova which shows the typical spectral features of Type la supernovae (SNe Ia) near maximum light, but also apparent hydrogen features that have been absent in SNe Ia (Hamuy et al. 2003). We have calculated hydrodynamical models for the interaction between the SN la ejecta and the H-rich circumstellar medium (CSM) to reproduce the observed features of SN 2002ic. Based on our modeling, possible progenitor systems of SN 2002ic are discussed.
