The Energetic X-ray Imaging Survey Telescope (EXIST) is a proposed mission to survey the hard X-ray sky (5 - 600 keV) for Active Galactic Nulcei, Gamma-Ray Bursts, stellar mass black holes, and steady and transient hard X-ray emission from other sources. EXIST would fulfill all the requirements for a Black Hole Finder Probe that is part of NASA's Beyond Einstein initiative. The central detector on the EXIST mission is a high-energy telescope that uses between 6 and 8 m2 of thick Cadmium Zinc Telluride detectors. The sensitivity of the high-energy telescope is limited by fluctuations in the number of background counts. In this contribution, we describe preliminary results from modeling of the background with the MGGPOD simulation package. We discuss the dominant backgrounds for EXIST. Furthermore, we describe plans for future simulations with MGGPOD.
