   The most important unanswered question concerning the Seyfert galaxy
   phenomenon is the fundamental nature of the energy source. Is this
   entirely an AGN "monster" or is there a significant contribution from
   massive hot stars? We propose observations of Mkn 266, NGC 7674, ESO
   362-G8, Mkn 1073, and Mkn 78, all Seyfert 2 galaxies with a
   circumnuclear starburst, to complete a small sample of such objects
   with ASCA data and thus increase our ability to distinguish between
   these energy sources. Combined with X-ray data of similar objects, this
   will provide a tool for testing the importance of starbursts in the
   Seyfert phenomenon, allow us to 'flag' Seyfert 2s with a strong
   starburst contribution, and determine whether Seyfert 2s with
   starbursts contain deeply buried Seyfert 1 nuclei.
