 TGC INDUSTRIES, INC.
 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 September 30, 2002

 NOTE A -- BASIS OF PRESENTATION

 The accompanying unaudited financial statements have been prepared in
 accordance with the instructions to Form 10-QSB and therefore do not include
 all information and footnotes necessary for a fair presentation of financial
 position, results of operations and changes in financial position in
 conformity with accounting principles generally accepted in the United States
 of America.

 NOTE B -- MANAGEMENT PRESENTATION

 In the opinion of management, all adjustments (consisting of normal recurring
 accruals) considered necessary for a fair presentation of financial position,
 results of operations, and changes in financial position have been included.
 The results of the interim periods are not necessarily indicative of results
 to be expected for the entire year.  For further information, refer to the
 financial statements and the footnotes thereto included in the Company's
 Annual Report for the year ended December 31, 2001 filed on Form 10-KSB.

 NOTE C -- EARNINGS (LOSS) PER SHARE

 Basic earnings (loss) per common share are based upon the weighted average
 number of shares of common stock outstanding.  Diluted earnings (loss) per
 share are based upon the weighted average number of common shares outstanding
 and, when dilutive, common shares issuable for stock options, warrants and
 convertible securities.  The effect of preferred stock dividends on the amount
 of loss available to common stockholders was $.01 and $.06 for the three
 months ended September 30, 2002 and 2001, respectively, and $.04 and $.20 for
 the nine months ended September 30, 2002 and 2001 respectively.

 Outstanding warrants that were not included in the diluted calculation because
 their effect would be anti-dilutive totaled 2,350,000 for the three and nine-
 month periods ended September 30, 2002, and 850,000 for the three and nine-
 month periods ended September 30, 2001.  Included in the 2,350,000 warrants
 are 1,500,000 detachable stock warrants issued in September, 2002, to certain
 investors in exchange for their financial commitment for a line of credit that
 expires December 31, 2002, in an amount up to $300,000. These warrants were
 valued at $45,000 or $.03 per warrant and are reflected as a reduction of
 current maturities of notes payable on the September 30, 2002, balance sheet.
 Outstanding options that were not included in the diluted calculation because
 their effect would be anti-dilutive totaled 232,100 for each of the three and
 nine month periods ended September 30, 2002; 232,100 and 267,834 for the three
 and nine month periods ended September 30, 2001, respectively.

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 September 30, 2002
 (Continued)


 NOTE D   DIVIDENDS

 Holders of the Company's Series C 8% Convertible Exchangeable Preferred Stock
 ("Series C Preferred Stock") will receive, when, as and if declared by the
 Board of Directors of the Company, dividends at a rate of 8% per annum.  The
 dividends are payable semi-annually during January and July of each year.  At
 September 30, 2002, cumulative dividends of approximately $81,340 were in
 arrears on the Company's Series C Preferred Stock.

 Holders of the Company's 8-1/2% Senior Convertible Preferred Stock (the
 "Senior Preferred Stock") will receive, when, as and if declared by the Board
 of Directors of the Company, dividends at a rate of 8-1/2% per annum.  The
 dividends are payable semi-annually during June and December of each year.
 Dividends paid during 2000, on the Senior Preferred Stock, were paid in
 additional shares of Senior Preferred Stock, in accordance with the terms of
 the Statement of Resolution Establishing the Senior Preferred Stock.  In
 addition, the holders elected to receive payment of the June and December
 2001, and the June 2002 dividends in additional shares of Senior Preferred
 Stock.  At September 30, 2002, there were no dividends in arrears on the
 Company's Senior Preferred Stock.

 NOTE E   CONVERSION OF SERIES C PREFERRED STOCK

 At a November 30, 2001 meeting, the Company's Board of Directors voted to
 reduce, on a post-reverse split basis, the conversion price of the Series C
 preferred Stock from $2.00 per share of Common Stock to $1.61 per share of
 Common Stock.  In addition, the Board of Directors voted to extend the
 conversion price increase date of the Series C Preferred Stock from the close
 of business on December 31, 2001 until the close of business on January 31,
 2002.  As a result, the conversion price was $1.61 per share of Common Stock
 if converted prior to the close of business on January 31, 2002.  After
 January 31, 2002, and prior to the close of business on December 31, 2002, the
 conversion price per share of Common Stock shall be $3.75.  Thereafter, the
 conversion price per share of Common Stock shall be $6.00.  As of January 31,
 2002, a total of 1,092,250 shares of Series C Preferred Stock had been
 converted into shares of Common Stock.  The 58,100 shares of Series C
 Preferred Stock that were not converted as of January 31, 2002, remain
 outstanding at October 31, 2002. Had these conversions taken place at the
 beginning of 2001, loss per common share would have been reduced by $0.05 and
 $0.36 for the three and nine month periods ended September 30, 2001,
 respectively.

 ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS.

 RESULTS OF OPERATIONS

 TGC Industries, Inc. ("TGC") continues to be adversely effected by the reduced
 level of seismic activity in the U.S. by the oil and gas exploration
 companies, the excess of domestic land based geophysical crews and very
 competitive pricing.  In addition, TGC's crew experienced unusually adverse


                                    8
 weather conditions during the third quarter of 2002.  As a result, TGC
 reported a net loss, before dividend requirements on preferred stock, of
 $670,189 on revenue of $1,126,169, for the three month period ended September
 30, 2002 compared with net income, before dividend requirements on preferred
 stock, of $45,106 on revenue of $3,545,427 for the same period of 2001.  Loss
 per common share, on a basic and diluted basis, was $.13 for the three month
 period ended September 30, 2002, compared with a loss per common share of $.05
 for the same period of 2001.

 For the nine month period ended September 30, 2002, TGC reported a net loss,
 before dividend requirements on preferred stock, of $852,628 on revenue of
 $5,698,438, compared with a net loss, before dividend requirements on
 preferred stock, of $789,209 on revenue of $7,001,059 for the same period of
 2001.  Loss per common share, on a basic and diluted basis, was $.20 for the
 nine month period ended September 30, 2002, compared with a loss per common
 share of $.54 for the same period of 2001.

 There are a significantly greater number of common shares outstanding at
 September 30, 2002, than were outstanding at September 30, 2001.  This
 increase resulted from the conversion of 977,550 shares of Series C Preferred
 Stock into 3,030,539 shares of Common Stock during the first quarter of 2002.
 See Note E for additional information and the effect on the loss per share in
 2001 had these conversions taken place at the beginning of 2001.

 As a result of reporting a loss, allocable to common stockholders, for the
 three and nine month periods ended September 30, 2002 and 2001, the number of
 common shares used in the diluted loss per share computation does not include
 any common shares issuable for stock options, warrants or convertible
 securities because the effect of their inclusion would be anti-dilutive.

 As previously stated, TGC's seismic crew continued to experience adverse
 weather conditions during the third quarter of 2002.  Because oil and gas
 exploration companies continue to curtail their domestic oil and gas
 exploration programs, there continues to be excess capacity in the land-based
 geophysical services industry and pricing remains very competitive. As a
 result, management continues to monitor expenses and, where possible,
 implement cost containment programs to remain competitive through this
 continued period of reduced industry activity.  In the opinion of management,
 despite the need for more U.S. energy self-sufficiency and the industry having
 favorable longer-term prospects, there are not yet clear indications of when
 the geophysical industry will show significant signs of improvement.  During
 2001, there were a number of consolidations and mergers in the geophysical
 industry.  In addition, a major seismic competitor recently announced it was
 shutting down all its United States and Canadian land-based seismic
 operations.  Management is hopeful that with fewer seismic crews available in
 the marketplace, TGC will be able to secure contracts with improved margins
 thereby improving its future performance.

 Non-cash charges for depreciation and amortization were $1,148,240 in the
 first nine months of 2002 compared with $1,211,711 for the same period of
 2001.

 At December 31, 2001, TGC had net operating loss carryforwards of
 approximately $8,100,000 available to offset future taxable income, which
 expire at various dates through 2021.


                                     9



 As previously reported, the Company was notified by Nasdaq that, in accordance
 with Marketplace Rule 4310(c)(8)(B), the Company's securities were being
 delisted from Nasdaq SmallCap Market at the opening of business on May 24,
 2002, due to the Company's Common Stock, as previously reported, having failed
 to maintain a minimum market value of publicly held shares of $1,000,000 as
 required by Marketplace Rule 4310(c)(7).  Also, as previously reported,
 following the delisting, the Company's securities now trade over-the-counter
 on the National Association of Securities Dealers, Inc. Over-The-Counter
 Bulletin Board System.

 FINANCIAL CONDITION

 Cash of $508,152 was used in operations during the first nine months of 2002
 compared with cash provided by operations of $1,345,560 for the same period
 of 2001.  This decrease in cash from operations in the first nine months of
 2002 was primarily the result of the net loss for the period, a decrease in
 billings in excess of cost and estimated earnings on uncompleted contracts and
 a decrease in accounts payable, partially offset by a decrease in accounts
 receivable, resulting from a decline in the level of activity during the first
 nine months of 2002 as compared with the last three months of 2001.  Net cash
 of $100,240 was used in investing activities during the first nine months of
 2002 for capital expenditures to replace certain vehicles and equipment.
 Principal payments of notes payable of $26,286, principal payments of capital
 lease obligations of $155,030 offset by proceeds from the issuance of notes
 payable of $179,861 resulted in net cash of $1,455 being used in financing
 activities during the first nine months of 2002.  In September 2002, TGC
 issued 1,500,000 detachable stock warrants to certain investors in exchange
 for their financial commitment for a line of credit that expires December 31,
 2002, in an amount up to $300,000.  During September 2002, TGC used $150,000
 of available funds under the line of credit.  TGC anticipates that available
 funds, together with anticipated cash flows generated from future operations
 will be sufficient to meet TGC's minimum lease and note payment obligations.

 Working capital increased $192,097 to $404,453 at September 30, 2002 from the
 December 31, 2001, working capital of $212,356.  The Company's current ratio
 was 1.5 at September 30, 2002, compared with 1.1 at December 31, 2001.
 Stockholders' equity decreased $807,628 to $2,219,155 at September 30, 2002
 from the December 31, 2001 balance of $3,026,783. This decrease was
 principally attributable to the net loss, before dividend requirements on
 preferred stock, of $852,628.

 In October 2002, one of the Company's geophysical service contracts was
 cancelled.  Management reported to the TGC Board of Directors that the
 contract represented approximately 55% of the Company's current backlog.
 Management believes, although there can be no assurance, (i) that the Company
 will secure additional contracts in amounts sufficient to replace the
 cancelled contract, and (ii) available funds, together with anticipated cash
 flows generated from future operations and the recently secured line of credit
 will be sufficient to fund the Company's existing and ongoing obligations.
