EXHIBIT A SOFTWARE Software Name: SimCAD tool Software Description: SimCAD is a Monte-Carlo based simulation software package for research, validation, and Computer Aided Design of economic systems. An economic system is treated as a state based model and defined through a set of endogenous and exogenous state variables which are updated through mechanisms and environmental processes, respectively. Behavioral models, which may be deterministic or stochastic, provide the evolution of the system within the action space of the mechanisms. Simulations can be run with a range of initial conditions and parameters for states, behaviors, mechanisms, and environmental processes to understand and visualize network behavior under various conditions.
