  by TGC Industries,&nbsp;Inc. (&#147;TGC&#148;) on April&nbsp;28, 2008, announcing its
  financial results for the first quarter of 2008.&#160; The Press Release is incorporated by

  <p style="margin:0in 0in .0001pt;text-indent:.45in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Press Release
  contains &#147;non-GAAP financial measures&#148; as defined in Item 10 of Regulation S-K
  of the Securities Exchange Act of 1934, as amended (the &#147;Exchange Act&#148;).&#160; In the Press Release, TGC has provided
  reconciliations of the non-GAAP financial measures to the most directly
  comparable financial measures calculated and presented in accordance with
  generally accepted accounting principles (&#147;GAAP&#148;) in the United States.&#160; Management of TGC believes that investors&#146;
  understanding of the Company&#146;s performance is enhanced by disclosing these
  non-GAAP financial measures as a reasonable basis for comparison of the Company&#146;s
  ongoing results of operations.&#160; These
  non-GAAP measures should not be considered a substitute for GAAP-basis measures
  and results.&#160; Our non-GAAP measures may
  not be comparable to non-GAAP measures of other companies.</font></p>

  Item 2.02.
  Results of Operations and Financial Condition
  .
  Attached hereto as
  Exhibit 99.1 is a copy of the press release (the "Press Release") issued
  by TGC Industries, Inc. ("TGC") on April 28, 2008, announcing its
  financial results for the first quarter of 2008.  The Press Release is incorporated by
  reference into this Item 2.02, and the foregoing description of the Press
  Release is qualified in its entirety by reference to this exhibit.
  The Press Release
  contains "non-GAAP financial measures" as defined in Item 10 of Regulation S-K
  of the Securities Exchange Act of 1934, as amended (the "Exchange Act").  In the Press Release, TGC has provided
  reconciliations of the non-GAAP financial measures to the most directly
  comparable financial measures calculated and presented in accordance with
  generally accepted accounting principles ("GAAP") in the United States.  Management of TGC believes that investors'
  understanding of the Company's performance is enhanced by disclosing these
  non-GAAP financial measures as a reasonable basis for comparison of the Company's
  ongoing results of operations.  These
  non-GAAP measures should not be considered a substitute for GAAP-basis measures
  and results.  Our non-GAAP measures may
  not be comparable to non-GAAP measures of other companies.
  Pursuant to
  General Instruction B.2 of Form 8-K, the information in this Form 8-K,
  including the exhibit, shall not be deemed "filed" for purposes of Section 18
