Pursuant to the terms of the merger agreement, at the effective time of the merger, TGC shareholders will receive 0.188 shares of Dawson stock for every one share of TGC stock, provided that the average of the volume weighted average price of Dawson common stock on the NASDAQ during the ten consecutive trading days ending on the second business day prior to the date of the shareholders’ meetings of Dawson and TGC to be called for the purpose of approving the transaction is equal to or greater than $32.54 but less than or equal to $52.54. In the event that the average of the volume weighted average price of Dawson’s common stock is outside of that range, then the parties, at their respective option, shall be entitled to terminate the transaction following good faith negotiations to determine a modified, mutually acceptable exchange ratio. For the ten consecutive trading days ended March 18, 2011, the average of the volume weighted average price of Dawson’s common stock was $44.16.

At the closing of the transaction, it is anticipated that Dawson will issue approximately 3.7 million shares in exchange for the approximately 19.6 million shares of TGC stock outstanding.
