(1)    The aggregate intrinsic value above is obtained by subtracting the exercise price from the estimated fair value of the underlying shares and multiplying this result by the related number of options outstanding and exercisable as of the period end date. There is no intrinsic value if the exercise price exceeds the fair value of the underlying shares. The estimated fair value of the shares is based on the closing price of the stock of $3.37 as of September 30, 2020 and $4.01 as of December 29, 2019.

(2)     Includes the 65,000 shares forfeited by the Company’s former Chief Financial Officer as a result of his October 2019 departure.
