Based on the estimated annual quantity of 400 units and the term of 60 months, the total quantity for the contract period would be 2,400 units (400 units/year * 6 years, considering a 5-year base period and potentially an additional year if options are exercised, but since the document does not explicitly mention options, we will consider the base period for calculation: 400 units/year * 5 years = 2,000 units). Assuming an average price per unit, the total contract value could range from $100,000 to $1,000,000, depending on the price per unit, which could be influenced by factors such as material costs, production complexity, and market conditions. For example, if the price per unit is around $50, the total contract value would be $100,000 (2,000 units * $50/unit), and if the price per unit is around $500, the total contract value would be $1,000,000 (2,000 units * $500/unit).
