We propose the first observations of NGC 5128 with WF/PC-2 to study the detailed morphology of the dust lane. We will resolve the stellar associations and determine the number, luminosities and spectral types of the sources seen along the edge of the dust lane in earlier observations with WF/PC-I. We will quantitatively check the interpretation that the X-ray ridges parallel to the dust lane are caused by massive X-ray binaries associated with young stars. Simultaneously, we will study the disk itself -- mapping the position of the stars and stellar associations along both north and south edges of the disk, possibly observing a significant number within the dust lane, and comparing the source distribution with the observed dust lane morphology, we will determine if the clustering of the bright sources is a projection of sources evenly distributed in or on a warped disk, or caused by interaction between the disk and the galaxy. Simultaneously, the possible scattering cloud near the nucleus will be studied using HST's highest available resolution in V and I.
