TGC INDUSTRIES, INC.
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
March 31, 2004

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, 2003
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 income (loss) available to common stockholders
was $.01 and $(.01) for the three months ended March 31, 2004 and 2003,
respectively.

Outstanding warrants that were not included in the diluted calculation
because their effect would be anti-dilutive totaled 8,000 and 2,350,000 for
the three-month period ended March 31, 2004 and 2003, respectively.
Outstanding options that were not included in the diluted calculation
because their effect would be anti-dilutive totaled 143,000 and 222,100 for
the three months ended March 31, 2004 and 2003, respectively.

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 March 31, 2004, cumulative dividends of $116,200 were in arrears
on the Company's Series C Preferred Stock.

NOTE D   DIVIDENDS - (Continued)

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 2001, 2002 and 2003
dividends in additional shares of Senior Preferred Stock.  At March 31,
2004, there were no dividends in arrears on the Company's Senior Preferred
Stock.

NOTE E   INCOME TAXES

At December 31, 2003, the Company had net operating loss carryforwards of
approximately $7,900,000 available to offset future taxable income, which
expire at various dates through 2023.  Current year federal taxable income
is being offset with net operating loss carryforwards, therefore, no federal
tax expense is reflected on the statements of operations.  Presently
deferred tax assets are fully reserved.

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

RESULTS OF OPERATIONS

The Company experienced an increase in demand for its services in late 2003
and secured a sufficient number of contracts to keep both of its crews
employed during the first quarter of 2004.  As a result, TGC reported net
income, before dividend requirements on preferred stock, of $789,515 on
revenue of $2,970,872, for the three month period ended March 31, 2004
compared with a net loss, before dividend requirements on preferred stock,
of $43,479 on revenue of $1,601,805 for the same period of 2003.  Income per
common share, on a basic and diluted basis, was $.13 and $.07, respectively,
for the three month period ended March 31, 2004, compared with a loss per
common share, on a basic and diluted basis, of $.02 for the same period of
2003.  At December 31, 2003, TGC had net operating loss carryforwards of
approximately $7,900,000 available to offset future taxable income, which
expire at various dates through 2023. As a result, the basic and diluted
earnings per common share for the three months ended March 31, 2004, was
based on net income before any provision for income taxes.  See Note E.

The number of common shares used in the (loss) per share computation for the
three month period ended March 31, 2003 do not include any common shares
issuable for stock options, warrants or convertible securities because the
effect of their inclusion would be anti-dilutive.


                                       8


Oil and gas exploration companies have recently increased the level of
activity in their domestic oil and gas exploration programs.  Though there
can be no assurance, should this increased level of activity in the industry
continue, management believes TGC may secure enough contracts to enable the
Company to improve its performance during 2004 compared with 2003.

Non-cash charges for depreciation and amortization were $194,360 in the
first three months of 2004 compared with $373,546 for the same period of
2003.

FINANCIAL CONDITION

Cash of $1,670,040 was provided by operations during the first three months
of 2004 compared with cash provided by operations of $604,189 for the same
period of 2003. This increase was primarily the result of an increasing
level of activity in the first three months of 2004 compared with the same
period of 2003.  During the first three months of 2004, $581,809 was used in
investing activities for capital expenditures for additional vehicles and
seismic equipment.  Principal payments of notes payable of $638 along with
principal payments of capital lease obligations of $30,929 resulted in net
cash of $31,567 being used in financing activities during the first three
months of 2004. 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.

In September 2002, TGC issued 1,500,000 stock warrants to certain directors
in exchange for a line of credit, that expired December 31, 2002, in an
amount up to $300,000.  The warrants cover 1,500,000 shares of Common Stock,
expire on September 10, 2012, and are exercisable at $.20 per whole share.
During September 2002, TGC borrowed $150,000 of the available funds.  The
promissory notes, which bore interest at 6.75% per annum, were paid in full
during December 2002 and January 2003.

In March 2003, the same group of directors committed to provide a line of
credit up to $300,000 through December 31, 2003.  Warrants covering 750,000
shares of Common Stock were issued in consideration for the commitment to
provide the line of credit.  The warrants expire on June 12, 2013, and are
exercisable at $.20 per whole share.  The Company had no borrowings against
the line of credit in 2003.

Working capital increased $342,896 to $1,669,490 at March 31, 2004 from the
December 31, 2003, working capital of $1,326,594.  The Company's current
ratio was 1.4 at March 31, 2004, compared with 3.1 at December 31, 2003.
Stockholders' equity increased $804,067 to $2,747,406 at March 31, 2004 from
the December 31, 2003 balance of $1,943,339.   This increase was primarily
attributable to the net income, before dividend requirements on preferred
stock, of $789,515.

Management believes, although there can be no assurance, that available
funds together with anticipated cash flows generated from future operations
will be sufficient to meet the Company's cash needs during 2004.
