ITEM 1. DESCRIPTION OF BUSINESS.

     TGC Industries, Inc. ("TGC" or the "Company") is a Texas corporation
engaged in the geophysical service business, primarily conducting Three-D ("3-
D") surveys for clients in the oil and gas business.  TGC's principal business
office is located at 1304 Summit Avenue, Suite 2, Plano, Texas 75074.
(Telephone: 972-881-1099).

                                 History

     In April 1980, Supreme Industries, Inc., formerly ESI Industries, Inc.,
("Supreme") formed a wholly owned subsidiary that acquired certain equipment,
instruments, and related supplies of Tidelands Geophysical Co., Inc.
("Tidelands"), a Houston-based corporation that had been organized in 1967 and
was engaged in the business of conducting seismic, gravity, and magnetic
surveys under contracts to companies in the exploration for oil and gas.  In
July 1986, Tidelands' name was changed to TGC Industries, Inc. ("TGC").  On
June 30, 1986, the Board of Directors of Supreme and TGC approved a spin-off
whereby substantially all of the shares of TGC owned by Supreme were
distributed as a stock dividend to Supreme security holders.

     On July 30, 1993, TGC acquired, through a wholly owned subsidiary, Chase
Packaging Corporation ("Chase"), a specialty packaging business, principally
supplying products to the agricultural industry, through the purchase of
certain assets of the Chase Packaging division of Union Camp Corporation.

     In June 1996, the Board of Directors of TGC approved the spin-off of
Chase, effective July 31, 1996, whereby all of the shares of Chase owned by
TGC were distributed as a stock dividend to the shareholders of TGC under the
terms of the spin-off transaction. Pursuant to the terms of the spin-off, and
following clearance by the Securities and Exchange Commission on March 7,
1997, the holders of TGC's Common Stock and, on an as-if-converted basis, the
holders of TGC's Series C 8% Convertible Exchangeable Preferred Stock ("Series
C Preferred Stock") received the dividend distribution of Chase Common Stock.

     During July 1996, the Company issued 1,150,350 shares of Series C
Preferred Stock in a private placement offering with gross proceeds of
approximately $5,800,000.

     The Series C Preferred Stock sold in the private placement entitles the
holder to receive cumulative cash dividends as, when and if declared by the
Board of Directors at a rate of 8% per annum prior to any dividend or
distribution in cash or other property on any class or series of stock junior
to the Series C Preferred Stock.  The dividends on the Series C Preferred
Stock are payable as, when and if declared by the Board of Directors on




                                    2


January 1 and July 1 of each year, commencing January 1, 1997.  The dividend
on the Series C Preferred Stock is cumulative.

     From the proceeds of the private placement, TGC made a capital
contribution to Chase of $2,716,403 to facilitate the spin-off; and TGC
retained $2,000,000 for the purchase of state-of-the-art geophysical recording
equipment.  Under the terms of the spin-off, the effective date of which was
July, 31, 1996, TGC completed the spin-off of the business and assets relating
to the Chase operations, except TGC retained the Portland, Oregon facility and
canceled all inter-company debt owed by Chase to TGC.  The distribution of
Chase Stock was March 7, 1997.  On March 18, 1997, TGC sold the Portland,
Oregon facility for $2,430,000 and applied such proceeds in satisfaction of
the mortgage indebtedness with respect to such facility and in satisfaction of
a debt obligation owing by TGC to Chase to pay to Chase any such proceeds in
excess of the amount of the mortgage indebtedness.

     As of July 31, 1996, the effective date of the spin-off, TGC Industries,
Inc.'s only business has been the geophysical service business, primarily
conducting Three-D ("3-D") surveys for clients in the oil and gas business.

     On December 13, 1999, WEDGE Energy Services, L.L.C., ("WEDGE Energy") an
affiliate of WEDGE Group Incorporated, a diversified Houston, Texas firm with
interests in oil and gas services, purchased a $2,500,000 8.5% Convertible
Subordinated Debenture, Series B due December 1, 2009 (the "Debenture"), of
the Company.  Proceeds of the financing together with other available funds
were utilized for working capital and an expanded capital expenditure program.
The Debenture, at WEDGE's option, could be converted into either preferred
stock or common at a price of $1.15 per share.

The holders of the Company's outstanding Series C Preferred Stock, voted at
the Annual Meeting held May 11, 2000, to consent to a new series of 8.5%
Senior Convertible Preferred Stock ("Senior Preferred Stock").  The
affirmative vote of the holders of two-thirds (2/3) of the outstanding shares
of Series C Preferred Stock approved the new series of Senior Preferred Stock.
As a result of the consent to the new series of Senior Preferred Stock by the
Series C Preferred Stock shareholders and in accordance with the terms of the
Debenture Agreement, WEDGE Energy, on May 17, 2000, converted its Debenture
plus accrued interest into 2,252,445 shares of Senior Preferred Stock.  Per
the Debenture Agreement, dividends on the Senior Preferred Stock have been
paid by the issuance of additional shares of Senior Preferred Stock through
December 1, 2002.  As a result, 530,263 shares of Senior Preferred Stock have
been issued to WEDGE Energy as dividend payments from June 1, 2000, through
December 1, 2002.

               General Description of the Company's Business

                           Geophysical Business

     Since its formation, TGC has engaged in the domestic geophysical services
business principally through conducting seismic surveys and to a lesser extent
through sales of gravity information from the Company's Data Bank to companies
engaged in the exploration for oil and gas in the United States.  Geophysics
is the study of the structure and composition of the earth's interior and
involves the measuring and interpretation of the earth's properties with




                                     3


appropriate instruments.  Such studies are generally conducted by means of
surveys performed by field crews employing seismic, gravity, or magnetic
instruments to acquire data that is then interpreted by various means to
obtain useful information for oil and gas companies.  The two survey
techniques used by the Company in acquiring geophysical data are seismic and
gravity.  Land seismic surveys are the Company's principal method of data
acquisition and are by far the most widely used geophysical technique.  TGC's
seismic crews use dynamite and vibroseis as energy sources for such surveys.
The processing and interpretation of seismic data acquired by TGC are
transmitted by the Company to data processing centers (not owned or operated
by the Company) designated by the clients for processing.

     The Company's Data Bank contains gravity data, and to a lesser extent
magnetic data, from many of the major oil and gas producing areas located
within the United States.  TGC does not have a seismic data bank.  Data Bank
information has been amassed through participatory surveys as well as
speculative surveys funded by TGC alone.  All data and interpretations may be
licensed to customers at a fraction of the cost of newly acquired data.

     In January 2002, the Company entered into a two year Joint Venture
Agreement (the "Joint Venture") with a gravity data processing center, (the
"Processing Center").  Per the Joint Venture the Company will furnish the
Processing Center with approximately 100,000 stations of the Company's
digitized gravity data, and the Processing Center, using industry standards
along with the latest technological gravity data processing software and
techniques will process the digitized data producing a data set (the "Data
Set").  During the term of this Agreement the Company and the Processing
Center will endeavor to market and license the Data Set.  In consideration for
the Processing Center's unique state-of-the-art gravity processing software
and techniques, upon licensing by the Company or the Processing Center of any
or all of the Data Set, the Company agrees to pay the Processing Center a
twenty percent commission.  Upon expiration of the Joint Venture, the Data Set
and all related information provided the Processing Center will be returned to
the Company.  Revenue from the licensing of gravity data represents a small
portion of the Company's total revenue, however, because the Data Bank has
been fully amortized and only minimal expenses are incurred with each license
agreement, revenues from the licensing of gravity data are very profitable.

     As a service business, the Company's domestic geophysical services
business is not dependent upon the supply of raw materials or any other
products and, therefore, the Company does not have arrangements with any raw
material suppliers.

     The Company has the capability of utilizing two seismic crews to perform
its geophysical services and, in any given period, these crews may generate a
significant portion of their respective revenues from one or more clients.
For the year ended December 31, 2002, three customers accounted for thirty-
nine percent (39%), twelve percent (12%) and eleven percent (11%) of the
Company's revenue, respectively.  The Company enters into a general or master
agreement with each of its clients for the provision of geophysical services
and a supplementary agreement (which becomes a part of the general agreement)







                                    4


with respect to each particular job that the Company performs for a client.
Under the terms of such agreements, the Company generally contracts to supply
all personnel, transportation and equipment to perform seismic surveys for a
given prospect for a fixed price plus reimbursement for certain third party
charges.  The Company generally bills its clients on a progressive basis over
the term of the contract.  The Company is generally obligated to maintain
insurance against injury or damage to persons or equipment arising from the
performance of its services and to indemnify its customers against all claims
and liability arising therefrom.  Management believes this insurance coverage
is sufficient.

      Beginning approximately in mid 1998, activity in the U.S. Geophysical
Industry declined significantly due to a decline in the price of oil. As a
result, TGC reduced its operations to one crew in 1999 and continued to
operate one crew during 2000.  TGC experienced an increase in demand for its
services in 2001 securing a sufficient number of contracts to deploy a second
seismic crew during the second quarter of 2001.  TGC's other seismic crew was
employed the majority of 2001.  However, this increased level of activity did
not continue into 2002, and TGC reduced its operations to one crew in 2002.
This lower level of activity in 2002 resulted in a significant decline in
revenues and an increase in the net loss in 2002 compared with 2001. Excess
capacity remains in the land-based geophysical service industry and pricing
continues to be very competitive. Company management continues to monitor
expenses and, where possible, implement cost containment programs to remain
highly competitive through this continued period of reduced industry activity.
During 2001, there were a number of consolidations and mergers in the
geophysical industry.  In addition, a major seismic competitor announced in
late 2002 it was shutting down all its U.S. 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.

     In February 2002, the Company entered into an agreement with a
corporation to dispose of the Company's shot hole drilling equipment, and to
use the proceeds of the disposal to acquire five buggy-mounted Vibroseis units
and purchase certain additional equipment needed to make the Vibroseis
equipment compatible with the Company's recording equipment.  A one-year
$30,000 note payable to the corporation financed this additional equipment.
The acquisition of this equipment opens up an opportunity in an existing
market, in which the Company has not participated, thereby increasing its
bidding opportunities.  Though there can be no assurance, management believes
the Company will be successful in securing its share of existing business in
this market thereby improving its performance.

     As of December 31, 2002, TGC employed 56 employees, supporting one
seismic crew with a total of 49 crew members and direct support members.  The
Company believes its relationship with its employees to be satisfactory.


ITEM 2. DESCRIPTION OF PROPERTY.

     The Company's headquarters are in leased facilities located in Plano,
Texas from which it conducts all its current operations.  These facilities





                                      5


include 8,000 square feet of office and warehouse space and an outdoor storage
area of approximately 10,000 square feet.  The monthly rent is $5,505.  This
facility is used to house corporate offices and serves as the headquarters for
the geophysical business. The Company is not responsible for insuring the
facilities.  The condition of the Company's facilities is good and TGC
management believes that these properties are suitable and adequate for the
Company's foreseeable needs.


ITEM 3. LEGAL PROCEEDINGS.

     The Company is a defendant in various legal actions that arose out of the
normal course of business.  In the opinion of Management, none of the actions
will result in any significant loss to the Company.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     No matters were submitted by the Company, during the fourth quarter of
the fiscal year ended December 31, 2002, to a vote of the Company's security
holders, through the solicitation of proxies or otherwise.


                                Part II

ITEM 5. MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

     The Company's Common Stock traded on the NASDAQ SmallCap Market under the
symbol "TGCI" from September 25, 1994, until May 24, 2002.  As previously
reported, the Company was notified by NASDAQ of potential delisting of the
Company's Common Stock for: (1) having failed to maintain a minimum market
value of publicly held shares of $1,000,000 and (2) having failed to equal or
exceed the minimum bid price requirement of $1 per share, in each case for
thirty (30) consecutive trading days.  The Company, as a condition to
continued listing of its securities on the SmallCap Market, was required to
satisfy these requirements for a minimum of ten (10) consecutive trading days
by May 15, 2002 and August 13, 2002, respectively.  The Company's Common Stock
did not trade at sufficient levels, for ten (10) consecutive trading days, to
comply with the May 15, 2002 deadline.  As a result, the Company's securities
were delisted from NASDAQ SmallCap Market at the opening of business on May
24, 2002 and now trade over-the-counter on the National Association of
Securities Dealers, Inc. Over-The-Counter Bulletin Board System.  The Company
maintains its trading symbol "TGCI".

     The number of shareholders of record of TGCI's Common Stock as of March
20, 2003, was 115.  Due to the number of shares held in nominee or street
name, the Company believes that there are a significantly greater number of
beneficial owners of its Common Stock.  As of such date, CEDE & CO. held
4,184,070 shares in street name.  On March 20, 2003, TGC's Common Stock was
quoted at a closing bid price of $.09.  High and low sales prices of TGC's
Common Stock for the period of January 1, 2001, to December 31, 2002, were as
follows:

 The above sale quotations were furnished to TGC by the Pink Sheets LLC.
At a November 30, 2001 meeting, the Company's Board of Directors, in an effort to encourage the conversion of Series C Preferred Stock into shares of Common Stock, 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 was $3.75. Thereafter, the conversion price per share of Common Stock is $6.00. As of December 31, 2002, a total of 1,092,250 shares of Series C Preferred Stock had been converted into shares of Common Stock. As a result, 58,100 shares of Series C Preferred Stock remained outstanding at December 31, 2002. Dividends are payable on the Company's Common Stock at the discretion of the Board of Directors. In light of the working capital needs of the Company, it is unlikely that cash dividends will be declared and paid on the Company's Common Stock in the foreseeable future. ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS. Results of operations Revenues for the year ended December 31, 2002 were $6,262,206 compared with revenues of $10,101,117 for the year ended December 31, 2001. The Company incurred a net loss, before dividend requirements on preferred stock, of $(1,711,509) for the year ended December 31, 2002 compared with a net loss, 7 before dividend requirements on preferred stock of $(1,148,843) for the year ended December 31, 2001. Due to continued difficult industry conditions in 2002, TGC returned to a one-crew operation in 2002. The Company had operated two crews during the second half of 2001. As a result, TGC experienced a significant decline in revenues in 2002 from 2001. This decline in revenue caused TGC's cost of services, as a percentage of revenue, to increase to 112.2% in 2002 from 102.1% in 2001. Selling, general and administrative expense decreased to $884,572 in 2002 from $916,258 in 2001. This decrease was due primarily to a reduction in selling expense associated with the lower level of revenues. Interest expense decreased to $16,807 in 2002 from $18,067 in 2001. This decrease was attributable to the lower level of debt in 2002 compared with 2001. In September 2002, the Company issued 1,500,000 detachable stock warrants, with a value of $45,000, to certain investors in exchange for their financial commitment for a line of credit that expired December 31, 2002, in an amount up to $300,000. For over thirty years, TGC has successfully served the geophysical industry. However, due to a significant decline in spending for seismic services, that began in mid 1998, by a number of oil and gas clients as a result of significantly lower oil prices, TGC reduced its operations to one seismic acquisition crew in 1999. TGC continued to operate at this one crew level during 2000. Early in 2001, TGC experienced an increase in demand for its services securing a sufficient number of contracts to deploy a second seismic crew during the second quarter of 2001. Operating at a two-crew level enabled TGC to significantly increase revenues and decrease its losses in 2001. However, TGC was unable to secure sufficient contracts to maintain its two-crew operation returning to the one-crew level in 2002. As a result, TGC experienced a significant decline in revenues and a greater net loss in 2002. Excess capacity remains in the land-based geophysical service industry and pricing continues to be very competitive. Company management continues to monitor expenses and, where possible, implement cost containment programs to remain highly competitive through this continued period of reduced industry activity. During 2001, there were a number of consolidations and mergers in the geophysical industry and in late 2002 a major seismic competitor announced it was shutting down all its United States and Canadian land-based seismic operations. Though there can be no assurance, 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. In January 2002, the Company entered into a two year Joint Venture Agreement (the "Joint Venture") with a gravity data processing center, (the "Processing Center"). Per the Joint Venture the Company will furnish the Processing Center with approximately 100,000 stations of the Company's digitized gravity data, and the Processing Center, using industry standards along with the latest technological gravity data processing software and techniques will process the digitized data producing a data set (the "Data Set"). During the term of this Agreement the Company and the Processing Center will endeavor to market and license the Data Set. In consideration for 8 the Processing Center's unique state-of-the-art gravity processing software and techniques, upon licensing by the Company or the Processing Center of any or all of the Data Set, the Company agrees to pay the Processing Center a twenty percent commission. Upon expiration of the Joint Venture, the Data Set and all related information provided the Processing Center will be returned to the Company. Revenue from the licensing of gravity data represents a small portion of the Company's total revenue, however, because the Data Bank has been fully amortized and only minimal expenses are incurred with each license agreement, revenues from the licensing of gravity data are very profitable. In February 2002, the Company entered into an agreement with a corporation to dispose of the Company's shot hole drilling equipment, and to use the proceeds of the disposal to acquire five buggy-mounted Vibroseis units and purchase certain additional equipment needed to make the Vibroseis equipment compatible with the Company's recording equipment. A one-year $30,000 note payable to the corporation financed this additional equipment. The acquisition of this equipment opens up an opportunity in an existing market, in which the Company has not participated, thereby increasing its bidding opportunities. Though there can be no assurance, management believes the Company will be successful in securing its share of existing business in this market thereby improving its performance. At December 31, 2002, the Company had net operating loss carry forwards of approximately $9,000,000 available to offset future taxable income, which expire at various dates through 2022. Financial Condition Cash of $404,100 was used in operations for the twelve months ended December 31, 2002, compared with cash provided by operations of $1,435,767 for the same period of the prior year. The primary reason for the decrease in cash from operations in 2002 compared with 2001 was a significant decline in the level of operations. This reduced level of operations resulted in decreases in revenues, accounts receivable, accounts payable, billings in excess of costs and estimated earnings on uncompleted contracts and an increase in the net loss. Net cash of $70,377 was used in investing activities during 2002. This was the result of capital expenditures to replace certain vehicles and equipment that had become worn-out during 2002. Principal payments of debt obligations in the amount of $67,731, principal payments on capital lease obligations of $128,633, and proceeds of $150,000 from the issuance of debt resulted in net cash of $46,364 being used in financing activities in 2002. The capital leases entered into in 2002 were primarily for replacement of certain equipment and additional surveying equipment. The terms of these capital leases range in length from six months to three years. The Company anticipates that available funds, together with anticipated cash flows generated from future operations will be sufficient to meet the Company's minimum lease and note payment obligations. 9 Working capital decreased $348,170 to a deficit of $135,814 at December 31, 2002 from the December 31, 2001, working capital of $212,356. The Company's current ratio decreased to .9 to 1.0 at December 31, 2002 from 1.1 to 1.0 at December 31, 2001. Stockholders' equity decreased to $1,360,274 at December 31, 2002, from the December 31, 2001, balance of $3,026,783 due primarily to the net loss incurred in 2002 of $1,711,509. In September 2001, the Company entered into a three-year operating lease for the Company's headquarters facility located in Plano, Texas. The Company anticipates that available funds, together with anticipated cash flows generated from future operations will be sufficient to meet the Company's minimum rental payment obligations that are as follows: $67,041 in 2003, and $52,488 in 2004. During 2001, the Company entered into an unsecured revolving line of credit arrangement with a bank, providing for borrowings of up to $125,000. The facility bears interest at prime plus 1% (5.25% at December 31, 2002) per annum, and matures in October 2003. The Company had no borrowings under this arrangement at December 31, 2002 or 2001, but had committed the availability to irrevocable letters of credit totaling $125,000 which also expire in October 2003. Therefore, the Company had no borrowing availability under this line of credit at December 31, 2002 or 2001. The letters of credit, with an insurance company as beneficiary, are being used to guarantee continuing seismic insurance bonds totaling $125,000, issued by the insurance company to two states in which the Company performs seismic surveys. In the opinion of management, the chances that the insurance company will draw on the letters of credit are remote. In 2000, the Company issued 2,252,445 shares of 8.5% Senior Convertible Preferred Stock ("Senior Preferred Stock") to a debt holder in consideration for an outstanding debenture plus accrued interest, and in accordance with the terms of the Debenture Agreement, issued 103,490 additional shares of Senior Preferred Stock to the Senior Preferred stockholder as payment for 2000 dividends. At the election of the Senior Preferred stockholder, the Company issued 100,127, 104,383, 108,819, and 113,444 additional shares of Senior Preferred Stock to the Senior Preferred stockholders as payment for the June 1, 2001, December 1, 2001, June 1, 2002 and December 1, 2002 dividends, respectively, resulting in 2,782,708 shares outstanding at December 31, 2002. At a November 30, 2001 meeting, the Company's Board of Directors, in an effort to encourage the conversion of Series C 8% Convertible Exchangeable Preferred Stock ("Series C Preferred Stock") into shares of Common Stock, 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 was $3.75. Thereafter, the conversion price per share of Common Stock is $6.00. This action by the Board of Directors has resulted in 977,550 shares of Series C Preferred Stock being converted into 3,030,539 shares of Common Stock during 2002. As a result, 10 58,100 shares of Series C Preferred Stock remained outstanding at December 31, 2002 and the cumulative dividends in arrears on the Series C Preferred Stock were $92,960 at December 31, 2002. In September 2002, the Company issued 1,500,000 detachable stock warrants, valued at $45,000, to certain investors in exchange for their financial commitment for a line of credit that expired December 31, 2002, in an amount up to $300,000. During September 2002, the Company used $150,000 of available funds under the line of credit. At December 31, 2002, $120,000 remained outstanding under the line of credit and was paid by the Company in January 2003. 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 2003, so long as the Company's one crew is employed, of which there is no assurance. In addition, should the Company require additional capital, an investor group has committed to loan the Company up to $300,000. This report contains forward-looking statements which reflect the view of Company's management with respect to future events. Although management believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from such expectations are disclosed in the Company's Securities and Exchange Commission filings, and include, but are not limited to the dependence upon energy industry spending for seismic services, the unpredictable nature of forecasting weather, the potential for contract delay or cancellation, the potential for fluctuations in oil and gas prices, and the availability of capital resources. The forward-looking statements contained herein reflect the current views of the Company's management and the Company assumes no obligation to update the forward-looking statements or to update the reasons actual results could differ from those contemplated by such forward-looking statements.

The accompanying notes are an integral part of these statements. 18 TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS December 31, 2002 and 2001 NOTE A - NATURE OF OPERATIONS TGC Industries, Inc. (TGC or the Company) is engaged in the domestic geophysical services business and primarily conducts seismic surveys and sells gravity data to companies engaged in exploration in the oil and gas industry. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash Equivalents The Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. Trade Receivables Trade accounts receivable are recorded in accordance with terms and amounts as specified in the related contracts on an ongoing basis. The Company evaluates the collectibility of accounts receivable on a specific account basis using a combination of factors, including the age of the outstanding balances, evaluation of the customer's financial condition, and discussions with relevant Company personnel and with the customers directly. An allowance for doubtful accounts or direct write-off is recorded when it is determined that the receivable may not be collected, depending on the facts known and the probability of collection of the outstanding amount. Property and Equipment Property and equipment are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the individual assets ranging from 1 to 7 years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs are charged to expenses as incurred. Long-Lived Assets Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. For the purposes of evaluating the recoverability of long-lived assets, the recoverability test is performed using undiscounted cash flows estimated to be generated by those assets. Income Taxes Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes. 19 TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 2002 and 2001 NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition Revenues from conducting seismic surveys are recognized over the term of the contract using the percentage-of-completion method. Under this method, revenues are recognized on the units-of-production method. Revenues for the sale of gravity data are recognized when services are rendered. Stock-Based Compensation The Company has two stock-based employee compensation plans, which are described more fully in Note I. The Company accounts for those plans under the recognition and measurement principles of Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. No stock-based employee compensation cost is reflected in net income, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net loss and loss per share allocable to common stockholders if the Company had applied the fair value recognition provisions of Financial Accounting Standards Board ("FASB") Statement No. 123 ("SFAS 123"), "Accounting for Stock-Based Compensation, to stock-based employee compensation: Year ended December 31, _______________________ 2002 2001 ______ ______ Net loss allocable to common stockholders, as reported $(1,992,162) $(1,799,955) Deduct: Total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects (54,643) (64,230) _________ ________ Pro forma net loss allocable to common stockholders $(2,046,805) $(1,864,185) ========= ========= Loss per common share Basic and diluted - as reported $(.37) $(.75) == == Basic and diluted - pro forma $(.38) $(.77) == ==
Financial Instruments The Company's financial instruments recorded on the balance sheet include cash and cash equivalents, accounts receivable, accounts payable and debt. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term nature of these items. Fair value of long-term debt is based on rates available to the Company for debt with similar terms and maturities. 20 TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 2002 and 2001 NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Earnings (Loss) Per Share Basic earnings (loss) per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings (loss) per share is based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants and convertible securities. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. New Accounting Standards In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 142 ("SFAS 142"), "Goodwill and Intangible Assets," which revises the accounting for purchased goodwill and intangible assets. Under SFAS 142, goodwill and intangible assets with indefinite lives will no longer be amortized, but will be tested for impairment annually as well as in the event of an impairment indicator. The Company adopted SFAS 142 effective January 1, 2002. The adoption of this statement had no impact on the Company's financial position or results of operations. 21 TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 2002 and 2001 NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued In October 2001, the FASB issued Statement of Financial Accounting Standards No. 144 ("SFAS 144"), "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This statement supersedes Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("SFAS 121") and related literature and establishes a single accounting model, based on the framework established in SFAS 121, for long-lived assets to be disposed of by sale. The Company adopted SFAS 144 beginning January 1, 2002. The adoption of SFAS 144 had no impact on the Company's financial position or results of operations. In December 2002, the FASB issued Statement of Financial Accounting Standard No. 148 ("SFAS 148"), "Accounting for Stock-Based Compensation- Transition and Disclosure - an amendment of SFAS No. 123". SFAS 148 was issued to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, this Statement amends the disclosure requirements of SFAS 123 to require disclosures in both annual and interim financial statements about the method of accounting for stock- based employee compensation and the effect of the method used on reported results. Entities are still permitted to account for stock-based compensation programs using the intrinsic value method prescribed in APB Opinion No. 25. The Company currently accounts for stock-based compensation using the intrinsic value method. The interim disclosure requirements prescribed by SFAS 148 are required for interim periods beginning after December 15, 2002. NOTE C - LIQUIDITY As indicated in the accompanying statements of operations and cash flows, the Company has incurred losses of approximately $1.7 million and $1.1 million for the years ended December 31, 2002 and 2001, respectively, and cash used in operations was $404,100 for the year ended December 31, 2002. Management believes that current cash on hand and cash generated from operations in 2003, based on current backlog, outstanding bids and contracts, will be adequate to fund operations through December 31, 2003. Should the Company require additional capital, an investor group has committed to loan the Company up to $300,000. 22 TGC Industries, Inc.

In connection with the issuance of subordinated notes payable during 1999, certain officers and directors received warrants covering 850,000 shares with a value of $391,000. These warrants have a strike price of $.30 and expire on July 31, 2009. Effective January 1, 2001, 10,000 warrants covering 3,333 shares of common stock were exercised and 849,674 warrants covering 283,224 shares of common stock expired. Per the warrant agreement, any unexercised warrants were automatically deemed exercised at the rate of one share of the Company's common stock for each 30 warrants held.

These warrants have a strike price of $.20 and expire on September 12, 2012. As the strike price is below the par value of the Company's common stock, and therefore not currently exercisable at $.20, the warrant agreements contain a provision whereby in the event the per share par value is not reduced to $.01 before March 10, 2004, each warrant certificate entitles the holder to purchase (in lieu of one share of common stock) one unit, such unit consisting of one share of the Company's common stock and one warrant containing the same terms and provisions as the current warrant, at the then per share par value of the common stock per unit.

At a November 30, 2001 meeting, the Company's Board of Directors approved amendments to the conversion terms of the Series C Preferred Stock. The amendments were as follows: the conversion price was reduced from $2.00 per share to $1.61 per share and the date of the conversion price increase to $3.75 per share was delayed from December 31, 2001, until January 31, 2002. The subsequent date of the increase in the conversion price to $6.00 per share remained December 31, 2002. In January 2002, the Series C Preferred shareholders converted 977,550 shares of Series C Preferred Stock into 3,030,539 shares of common stock.

In 2000, the Company issued 2,252,445 shares of 8.5% Senior Convertible Preferred Stock (Senior Preferred Stock) to a debt holder in consideration for an outstanding debenture plus accrued interest, and in accordance with the terms of the agreement, issued 103,490 additional shares of Senior Preferred Stock to the Senior Preferred stockholder as payment for 2000 dividends.
