The shares were converted into the right to receive 0.40 shares of Columbia common stock in exchange for each share of the Company's common stock held on the Closing Date of the Merger described under "Remarks" below. Each share of the Company's common stock had a market value of $15.20 per share on the Closing Date, based on the closing price of Columbia's common stock on the Closing Date of $37.99. Cash will be paid in lieu of fractional shares, based on the average closing price of Columbia's common stock for the 20 consecutive Nasdaq trading days ending on September 23, 2021, of $34.81 per share (the "Parent Average Closing Price"), calculated in accordance with the terms of the Merger Agreement referenced under "Remarks" below.
