    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
    September 30, 2001

    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 generally accepted accounting principles.

    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, 2000 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 $.06 and $.08 for the three months ended September 30, 2001 and
    2000, respectively, and $.20 and $.18 for the nine months ended
    September 30, 2001 and 2000, respectively.

    Outstanding warrants that were not included in the diluted calculation
    because their effect would be anti-dilutive totaled 850,000 for each of
    the three and nine month periods ended September 30, 2001, and
    1,136,575 for each of the three and nine month periods ended September
    30, 2000.  Outstanding options that were not included in the diluted
    calculation because their effect would be anti-dilutive totaled 241,100
    for each of the three and nine month periods ended September 30, 2001,
    and 176,497 for each of the three and nine month periods ended
    September 30, 2000.

    income, before dividend requirements on preferred stock, of $45,106 for
    the three month period ended September 30, 2001, compared with revenue
    of $2,589,305 and net income, before dividend requirements on preferred
    stock, of $42,159 for 2000.  Loss allocable to common stockholders per
    common share, on a basic and diluted basis, was $(.05) for the three
    month period ended September 30, 2001, compared with a loss per common
    share of $(.06) for 2000.

    $7,001,059 and a net loss, before dividend requirements on preferred
    stock, of $(789,209).  This compares with revenue of $4,387,672 and a
    net loss, before dividend requirements on preferred stock, of
    $(1,232,600) for the same period in 2000.  Loss allocable to common
    stockholders per common share, on a basic and diluted basis, was $(.54)

                            8
    As a result of TGC reporting a loss allocable to common stockholders
    for the three and nine month periods ended September 30, 2001 and 2000,
    the number of shares used in the 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.

    TGC was awarded and completed sufficient work to return to
    profitability, before dividend requirements on preferred stock, during
    the third quarter of 2001 showing a significant improvement over the
    first two quarters of 2001. TGC had a backlog of $6,173,700 at
    September 30, 2001.  Despite the recent difficult industry conditions,
    management believes that bidding activity for seismic services will
    remain at or near current levels and the geophysical services industry
    has favorable long-term prospects.

    Non-cash charges for depreciation and amortization were $1,211,711 for
    the nine month period ended September 30, 2001 compared with $1,235,559
    for the same period of 2000.

    At December 31, 2000, TGC had net operating loss carryforwards of
    approximately $7,800,000 available to offset future taxable income,
    which expire at various dates through 2020.

    FINANCIAL CONDITION

    Cash of $1,345,560 was provided from operations for the nine month
    period ended September 30, 2001 compared with cash provided from
    operations of $261,783 for the same period of 2000.  This increase was
    primarily the result of a decrease in accounts receivable, and a
    reduction in the net loss.  Cash used in investing activities for the
    nine month periods ended September 30, 2001 and 2000, was $328,537 and
    $509,435, respectively.  These funds were used principally for the
    addition of equipment.  Cash used in financing activities for the nine
    month periods ended September 30, 2001 and 2000, was $155,060 and
    $641,624, respectively.  These funds were used primarily for principal
    payments of debt obligations.

    Working capital increased $117,529 to $447,063 from the December 31,
    2000 balance of $329,534.  The Company's current ratio was 1.29 at
    September 30, 2001, compared with 1.36 at December 31, 2000.
    Stockholders' equity decreased $785,442 from the December 31, 2000
    balance of $4,171,860 to $3,386,418 at September 30, 2001.   This
    decrease was primarily attributable to the net loss, before dividend
    requirements on preferred stock, of $789,209.

    The Company anticipates that available funds, together with anticipated
    cash flows generated from future operations will be sufficient to meet
    the Company's cash needs during 2001.
