("New Dawson") whereby each share of Old Dawson common stock, par value $0.33 1/3 per share, was converted into 1.760 shares of New Dawson common stock, par value $0.01 per share, having a market value based on the closing price of one share of New Dawson common stock on NASDAQ on the effective date of the Merger of $5.85 (as adjusted to reflect New Dawson's 1-for-3 reverse stock split, which occurred immediately prior to the Merger) per share and a cash payment being made for any fractional shares.
(2)	Includes 8,622 Restricted Stock Units, which are convertible at a rate of 1 unit for 1 share of Old Dawson common stock, par value $0.33 1/3 per share.

(3)	Includes 7,500 Restricted Stock Grants, which are convertible at a rate of 1 restricted share for 1 share of Old Dawson common stock, par value $0.33 1/3 per share. Each such restricted share was disposed of pursuant to the Merger in exchange for 1.760 corresponding restricted shares of New Dawson, subject to the same terms and conditions.
