The record date for the Annual Meeting will be March 15, 2000. Historically, TGC has held its annual meeting in June; however, for efficiency and cost considerations, the Board of Directors of TGC has determined to address matters which were to be voted on at a special meeting of shareholders (as reported in the Company's Form 8-K filing dated December 29, 1999, and in a preliminary proxy statement filed February 11, 2000), at the annual meeting and to move forward the date of the annual meeting to May 11, 2000. The matters to be voted on at the annual meeting are as follows: (1) To elect seven (7) directors to serve until the next annual meeting, two (2) of such directors being new nominees to the Board of Directors selected by WEDGE Energy Services, L.L.C. pursuant to the terms of the Debenture Purchase Agreement in connection with the purchase by WEDGE of a $2,500,000 Convertible Subordinated Debenture in December 1999; (2) To consent, by vote of the holders of TGC's outstanding shares of Preferred Stock, voting as a class, to a new series of 8-1/2 % Senior Convertible Preferred Stock. If the consent of the holders of 66- 2/3% of the outstanding shares of Preferred Stock is obtained, WEDGE is obligated to convert its $2,500,000 Convertible Subordinated Debenture into such Senior Preferred Stock. Such Debenture is convertible at a price of $1.15 per share; (3) To approve TGC's 1999 Stock Option Plan; and (4) To ratify the selection of Grant Thornton, LLP as independent auditors. TGC's Board of Directors will recommend that the shareholders vote in favor of each of the above matters. In another matter, TGC has received a favorable ruling from Nasdaq that TGC's securities have evidenced compliance with all continued listing criteria and that the Company's securities will continue to be listed on the Nasdaq SmallCap Market. As previously reported in the Company's Form 8-K filing dated December 29, 1999, the Company had a written hearing before the Nasdaq Listing Qualifications Panel on February 3, 2000.
