We calculate the $CP$ asymmetries in $B$ decays for the aspon model and show that they are typically smaller than those predicted from the standard model. A linear relation between the $CP$ asymmetries of different decay processes is obtained.REVTEX, 9 pages, IFP-486-UNC, NSF-PT-94-1, and UDHEP-01-94High Energy Physics - Phenomenologytext
