| §   | Level 1 – The valuation is based on quoted prices in active markets for identical instruments. |
|--------------------|------------------------------------------------------------------------------------------------------|

| §   | Level 2 – The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | Level 3 – The valuation is based on unobservable inputs that are supported by minimal or no market activity and that are significant to the fair value of the instrument.  Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar techniques that incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument, or valuations that require significant management judgment or estimation. |
