   We have discovered two regions of hard X-ray emission in the supernova
   remnant IC 443, coinciding with where its radio-bright shell overlaps a
   ring of molecular clouds. We have argued that the X-rays from these
   features are synchrotron emission from cosmic ray electrons with
   energies of ~10 TeV. Unfortunately, these hard features were at the
   edge of the ASCA GIS field of view during the previous observation, and
   appear to extend beyond it. We propose a 40 ks observation primarily to
   determine whether the hard X-ray ridge encompasses the entire region of
   shock/cloud interaction. In addition we will obtain the first SIS
   spectrum of the known hard X-ray regions.
