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
received the dividend distribution of Chase Common Stock. 

     During July 1996, the Company issued 1,150,350 shares of Series C 8%
Convertible Exchangeable Preferred Stock in a private placement offering with
gross proceeds of approximately $5,800,000.

     The 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
preferred stock.  The dividends on the Preferred Stock are payable as, when
and if declared by the Board of Directors on January 1 and July 1 of each
year, commencing January 1, 1997.  The dividend on the 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. 


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 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 as the primary energy source for
such surveys.

     In July 1996, the Company purchased an Opseis Eagle 24-BIT 1500 channel
recording system, cables and geophones for approximately $2,900,000, using
$2,000,000 from proceeds from the Company's preferred stock private
placement, a $750,000 equipment loan, and funds from internal cash flow.  In
late November 1996, the Company purchased a second 1000 channel Eagle system
using the proceeds and trade-in from TGC's two older systems along with
equipment financing of $855,000 and internal cash flow.  In 1997, TGC
purchased an additional 1500 channels utilizing equipment financing of
$2,242,685.  The greater precision and improved subsurface resolution
obtainable from 3-D seismic data have enabled energy companies in the U.S. to
better evaluate important subsurface features.  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.

     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, 1998, three customers accounted for twenty-
four percent (24%),twenty two percent (22%) and seventeen percent (17%) 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) 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.

     Prior to the second half of 1998, activity in the U.S. Geophysical
Industry had increased with the success and acceptance of 3-D surveys.  The
improved cost effectiveness gained from the data acquisition and processing
of 3-D surveys had resulted in increased profits for the U.S. operations of
the major and independent oil companies.  With these cost advantages and the
uncertainty of foreign operations, many of the major U.S. oil companies
increased participation in the domestic oil industry.  Beginning
approximately in mid 1998, activity declined significantly due to a decline
in the price of oil.  

     Due to a significant decline in spending for seismic services by a
number of oil and gas clients as a result of significantly lower oil prices,
TGC has reduced its operations to one seismic acquisition crew.  This
decrease in spending was primarily a result of the significant decline in oil
and gas prices (principally oil prices) during 1998.  TGC is continuing to
obtain contracts for work but at lower prices than in 1998.  As a result of
this reduced activity the first half of 1999 will not compare favorably with
1998.  Company management has activated expense reduction and cost
containment programs to remain highly competitive through this period of
reduced industry activity. 

     As of December 31, 1998, TGC employed 72 employees, supporting one
seismic crew with a total of 65 crewmembers 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
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
$4,460.  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.

     On March 18, 1997, TGC sold the Portland, Oregon facility formerly
utilized by Chase Packaging Corporation 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.

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.

     On November 5, 1998, shareholders approved an amendment to Article Four
of the Company's Articles of Incorporation, as amended, to effect a one-for-
three reverse stock split of the Company's Common Stock, whereby each three
shares of issued and outstanding Common Stock was converted and combined into
one share of Common Stock (the "Reverse Split").  The Common Stock commenced
trading on a post-Reverse Split basis on November 9, 1998.  

                                 Part II

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

     The Company's Common Stock has traded on the NASDAQ SmallCap Market
under the symbol "TGCI" since September 25, 1994.

     The number of shareholders of record of TGCI's Common Stock as of March
12, 1999, was 392.  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
748,746 shares in street name.  On March 18, 1999, TGC's Common Stock was
quoted at a closing price of $1.094.  High and low sales prices (adjusted for
the Reverse Split) of TGC's Common Stock for the period of January 1, 1997,
to December 31, 1998, were as follows:

The above sale quotations were furnished to TGC by the NASD. On November 6, 1998, the Company effected a one-for-three reverse stock split of its Common Stock, whereby each three shares of issued and outstanding Common Stock was converted and combined into one share of Common Stock. The Common Stock commenced trading on a post-Reverse Split basis on November 9, 1998. As a consequence of the Reverse Split: (1) pursuant to the provisions for adjustment of the conversion ratio of the Company's Preferred Stock, the conversion price per share of Common Stock on a post-Reverse Split basis increased from $0.75 to $2.25 per share; and (2) pursuant to the terms for adjustment to the exercise price of the Company's Common Share Purchase Warrants, each Warrant purchases on a post-Reverse Split basis, 1/3 of a share of Common Stock at a price of $1.125 per share of Common Stock. On November 2, 1998, the TGC Board of Directors voted to extend the expiration date of its outstanding Common Stock Purchase Warrants and to delay the increase in the conversion price of its Preferred Stock until December 31, 1999. On December 10, 1998, the Board of Directors voted to further extend the expiration date of its warrants and to delay the increase in the conversion price of its Preferred Stock until December 31, 2000. The Common Stock Purchase Warrants were otherwise scheduled to expire on December 31, 1998, and the conversion price of the Preferred Stock was otherwise scheduled to increase, following the conversion price adjustment described above, from $2.25 per share of Common Stock to $3.75 per share of Common Stock on December 31, 1998. As modified, after December 31, 2000 and prior to the close of business on December 31, 2001, the conversion price of the Preferred Stock will be $3.75 per share of Common Stock. Thereafter, the conversion price will be $6.00 per share of Common Stock. 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 Geophysical Operation (Continuing Operations) Revenues for the year ended December 31, 1998, increased to $17,073,506 from revenue of $16,307,577 for the year ended December 31, 1997. Net earnings before dividend requirements on preferred stock was $1,831,602 for the year ended December 31, 1998. Net earnings before dividend requirements on preferred stock was $1,306,039 for the year ended December 31, 1997. Included in the 1997 net earnings was a $170,000 income tax benefit. EBITDA was $3,872,761 or $.81 per share on a fully diluted basis for the year ended December 31, 1998, compared with $2,764,014 or $.57 per share on a fully diluted basis for the year ended December 31, 1997. The Company's shareholders, at a special meeting of shareholders on November 5, 1998, approved an Amendment to the Company's Articles of Incorporation to effect a one-for-three reverse stock split of its Common Stock (the "Reverse Split"). The Reverse Split was effected on November 6, 1998, and the Common Stock commenced trading on a post-Reverse Split basis on November 9, 1998. All references to number of shares, except shares authorized, and to per share information have been adjusted to reflect the reverse stock split on a retroactive basis. TGC's cost of services, as a percentage of revenue, decreased from 86.1% in 1997 to 80.9% in 1998. Selling, general and administrative expense, as a percentage of revenues, increased from 5.6% in 1997 to 6.8% in 1998. Interest expense increased by $59,322 in 1998 when compared to 1997 primarily as a result of the financing of additional geophysical equipment in the second half of 1997. Non-cash charges for depreciation and amortization were $1,778,454 in 1998 compared with $1,425,817 in 1997. During 1998, TGC purchased approximately $1,150,000 additional equipment to better serve our clients in their pursuit of Three-D ("3-D") seismic data acquisition. This additional equipment was financed with a combination of equipment-related financing and internal cash flow. Due to a significant decline in spending for seismic services by a number of oil and gas clients as a result of significantly lower oil prices, TGC has reduced its operations to one seismic acquisition crew. This decrease in spending was primarily a result of the significant decline in oil and gas prices (principally oil prices) during 1998. For over thirty years, TGC has successfully served the geophysical industry. The Company is continuing to obtain contracts for work but at lower prices than in 1998. As a result of this reduced activity the first half of 1999 will not compare favorably with 1998. Company management has activated expense reduction and cost containment programs to remain highly competitive through this period of reduced industry activity. Management is aggressively pursuing contract opportunities and believes that a recovery in the price of oil and gas in the second half of 1999 would not have a significant upward effect on 1999 results, but it could stop further deterioration and constitute a clear indication of better prospects for 2000 and 2001. 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, without limitation, the unpredictable nature of forecasting weather, the potential for contract delay or cancellation, and the potential for fluctuations in oil and gas prices. 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. At December 31, 1998, the Company had net operating loss carry forwards of approximately $3,600,000 available to offset future taxable income, which expires at various dates through 2013. Discontinued Operations During June 1996, the Board of Directors approved the spin-off of Chase Packaging Corporation ("Chase"), whereby all of the shares of Chase would be distributed as a stock dividend to the shareholders of TGC common stock and, on an as if converted basis, TGC preferred stock, effective July 31, 1996. The date of the distribution of Chase's stock was March 7, 1997. The spin- off distribution of Chase to TGC stockholders reduced stockholders' equity by $103,976, which represents the book value of the net assets of Chase as of March 7, 1997. In addition, on March 18, 1997, TGC sold the Portland, Oregon manufacturing facility of Chase for approximately $2,400,000, 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. Financial Condition Cash of $2,259,490 was provided by operations for the twelve months ended December 31, 1998, compared with cash provided by continuing operations of $2,426,320 for the same period of the prior year. The funds generated in 1998 were primarily attributable to net earnings before non-cash depreciation and amortization charges. Cash used in investing activities for 1998 was primarily for additions to equipment for geophysical field operations. In addition, during 1998, the Company financed the acquisition of geophysical equipment through notes payable in the amount of $778,131. Cash used in financing activities were primarily for the payment of principal payments on debt obligations in the amount of $1,386,194. Working capital deficit decreased $1,377,166 to $870,721 from the December 31, 1997, balance of $2,247,887, primarily as a result of a decrease in billings in excess of costs and estimated earnings on uncompleted contracts and trade accounts payable. The Company's current ratio increased to .72 to 1.0 at December 31, 1998, compared to .57 to 1.0 at December 31, 1997. Stockholders' equity increased to $5,127,856 at December 31, 1998, from the December 31, 1997, of $3,729,993 due primarily to the net earnings of the Company. During the fourth quarter of 1998, the Company renewed its revolving bank line of credit with a major bank in an amount of up to $1,000,000. The line of credit bears interest at prime plus 1.5%, is collateralized by equipment and accounts receivable and requires the maintenance of certain financial ratios. The Company began preparation for the year 2000 issues during 1996. In late 1996, TGC upgraded and replaced its accounting software. In addition, TGC installed a small personal computer network. The cost of these additions, which are year 2000 compliant, was approximately $15,000. TGC uses an outside source for its payroll services and has been assured by this vendor that its software is year 2000 compliant. TGC will need to make a few additional hardware upgrades in order for the total system to be year 2000 compliant. These upgrades will be completed by September 30, 1999, at which time the Company will be fully year 2000 compliant. The cost of these upgrades will be approximately $2,000. The Company anticipates that available funds, together with anticipated cash flows generated from future operations and amounts available under its revolving line of credit will be sufficient to meet the Company's cash needs during 1999, so long as one of the Company's two crews is employed, of which there is no assurance.

During 1997, the Company sold a manufacturing facility of its former wholly-owned Subsidiary, Chase Packaging Corporation (Chase). All proceeds were contributed to New Chase (Note C). During 1997, the Company spun-off New Chase (Note C) resulting in a stock dividend to TGC stockholders amounting to $103,976.

NOTES TO FINANCIAL STATEMENTS December 31, 1998 and 1997 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. 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. 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. Stock-Based Compensation Statement of Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based Compensation" encourages, but does not require, companies to record compensation cost for stock-based employee compensation plans at fair value. The Company has chosen to continue to account for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25 (APB 25), "Accounting for Stock Issued to Employees" and provides the required pro forma disclosures prescribed by SFAS 123. 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. TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1998 and 1997 NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Earnings Per Share Basic earnings per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings 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. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles 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. NOTE C - REORGANIZATION PLAN In May 1996, a formal plan was adopted to reorganize TGC and its former wholly-owned subsidiary. Pursuant to the plan, TGC liquidated the subsidiary, Chase Packaging Corporation (Old Chase), with TGC receiving all of Old Chase's properties and liabilities in cancellation of the Old Chase stock held by TGC. TGC formed a new wholly-owned subsidiary, New Chase Corporation (New Chase), and subsequently changed the name to Chase Packaging Corporation. TGC transferred all of the properties and liabilities received in the liquidation of Old Chase to New Chase, except TGC retained the manufacturing facility of Old Chase located in Portland, Oregon. On March 18, 1997, TGC sold the facility for proceeds of approximately $2,400,000. TGC 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 New Chase to pay to New Chase any such proceeds in excess of the amount of the mortgage indebtedness. During June 1996, the Board of Directors approved the spin-off of New Chase whereby all of the shares of New Chase would be distributed as a stock dividend to the shareholders of TGC common stock and, on an as if converted basis, TGC preferred stock, effective July 31, 1996. The New Chase common stock was distributed on March 7, 1997. The spin-off distribution of New Chase to TGC stockholders reduced stockholders' equity by $103,976, which represents the book value of the net assets of New Chase as of March 7, 1997.

Stock-Based Compensation Plans The Company's 1986 Incentive Stock Option Plan (the "1986 Plan") expired during July 1997. At December 31, 1998, options covering 6,335 shares of the Company's common stock were outstanding under the 1986 Plan. All options were exercisable at December 31, 1998, and will remain outstanding until they are exercised or canceled. TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1998 and 1997 NOTE G - STOCKHOLDERS' EQUITY - Continued The Company currently has in effect a 1993 Stock Option Plan (the "1993 Plan") covering a total of 283,334 shares of the Company's common stock, and options must be granted at prices not less than the market price at the date of grant. Options granted under the 1993 Plan must be exercised within five years from the date of grant. Options covering 60,005 shares are exercisable as follows: (i) one-third of the shares after the first twelve-month period following the date of grant, (ii) up to two-thirds of the shares after the first twenty-four month period following the date of grant, and (iii) all of the shares of stock subject to the option at any time after the first thirty-six month period following the date of grant. Options covering 35,000 shares are exercisable as follows: (i) one-third of the shares on January 1, 1999, and (ii) all of the shares after January 1, 2000. At December 31, 1998, outstanding options for 43,895 shares were exercisable. Options covering 37,114 shares were available for future grant.

The Company will continue to apply APB 25 and related interpretations in accounting for its stock-based compensation plans. Had compensation cost for the Company's stock grants been determined consistent with SFAS 123, the Company's net earnings and net earnings per common share for 1998 and 1997 would approximate the pro forma amounts indicated below: 1998 1997 As reported Pro forma As reported Pro forma Net earnings $1,831,602 $1,780,453 $1,306,039 $1,221,249 ========= ========= ========= ========= Net earnings allocable to common stockholders $1,379,862 $1,362,475 $850,399 $765,609 ========= ========= ========= ========= Earnings per common share Basic $.64 $.63 $.40 $.36 Diluted $.38 $.37 $.27 $.25
TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1998 and 1997 NOTE G - STOCKHOLDERS' EQUITY - Continued The effects of applying SFAS 123 in this pro forma disclosure are not indicative of future disclosures because they do not take into effect pro forma compensation expense related to grants made before December 31, 1994. The fair value of these options was estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions used for grants in 1998: expected volatility of 135%; risk- free interest rate of 5.41%; and expected life of 7 years. The weighted average fair value of options granted during 1998 was $.70. No options were granted during 1997.

Interested Directors, Officers, and Shareholders. (1) If paragraph (2) below is satisfied, no contract or transaction between the corporation and one or more of its directors or officers, or between the corporation and any other corporation, partnership, association or other organization in which one or more of the corporation's directors or officers are directors or officers or have a financial interest, shall be void or voidable solely for this reason, solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose. (2) Paragraph (1) above will apply only if: (a) The contract or transaction is fair as to the corporation as of the time it is authorized, approved, or ratified by the Board of Directors, a committee of the board, or the shareholders; (b) The material facts as to the relationship or interest of the director or officer and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative vote of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (c) The material facts as to the relationship or interest of the director or officer and as to the contract or transaction are disclosed or are known to the shareholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by a vote of the shareholders. (3) For purposes of paragraphs (1) and (2) above, common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction. b. Indemnification. (1) The corporation shall indemnify, to the extent provided in the following paragraphs, any person who is or was a director, officer, agent, or employee of the corporation and any person who serves or served at the corporation's request as a director, officer, agent, employee, partner, or trustee of another corporation or of a partnership, joint venture, trust, or other enterprise. In the event the provisions of indemnification set forth below are more restrictive than the provisions of indemnification allowed by Article 2.02-1 of the Texas Business Corporation Act, then such persons named above shall be indemnified to the full extent permitted by Article 2.02-1 of the Texas Business Corporation Act as it may exist from time to time. (2) In case of a suit by or in the right of the corporation against a person named in paragraph (1) above by reason of such person's holding a position named in such paragraph (1) hereafter referred to as a derivative suit, the corporation shall indemnify such person for reasonable expenses actually incurred by such person in connection with the defense or settlement of the suit, but only if such person satisfies the standard in paragraph (4) to follow. (3) In case of a threatened or pending suit, action, or proceeding (whether civil, criminal, administrative, or investigative), other than a derivative suit, hereafter referred to as a non-derivative suit, against a person named in paragraph (1) above by reason of such person's holding a position named in such paragraph (1), the corporation shall indemnify such person if such person satisfies the standard contained in paragraph (4), for amounts actually and reasonably incurred by such person in connection with the defense or settlement of the non-derivative suit as expenses (including court costs and attorneys' fees), amounts paid in settlement, judgments, and fines. (4) Whether in the nature of a derivative suit or non-derivative suit, a person named in Paragraph (1) above will be indemnified only if it is determined in accordance with paragraph (5) above that such person: (a) acted in good faith in the transaction which is the subject of the suit; (b) reasonably believed: (i) his conduct was in the best interests of the corporation; and (ii) in all other cases, that his conduct was not opposed to the best interests of the corporation; and (c) in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of a proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent will not, of itself, create a presumption that this person failed to satisfy the standard contained in this paragraph. (5) A determination that the standard of paragraph (4) above has been satisfied must be made: (a) by a majority vote of a quorum consisting of directors who at the time of the vote are not named defendants or respondents in the proceeding; or (b) if such quorum cannot be obtained, by a majority vote of a committee of the board of directors, designated to act in the matter by a majority vote of all directors, consisting solely of two or more directors who at the time of the vote are not named defendants or respondents in the proceeding; or (c) by special legal counsel selected by the board of directors or a committee of a board by vote as set forth in subparagraphs (a) and (b) above, or, if such quorum cannot be obtained and such committee cannot be established, by a majority vote of all directors; or (d) by the shareholders in a vote that excludes the vote of directors who are named defendants or respondents in the proceeding. (6) Authorization of indemnification and determination as to reasonableness of expenses must be made in the same manner as the determination that indemnification is permissible, except that if the determination that indemnification is permissible is made by special legal counsel, authorization of indemnification and determination as to reasonableness of expenses must be made in the manner specified by subparagraph (5)(c) above for the selection of special legal counsel. (7) The corporation may reimburse or pay in advance any reasonable expenses (including court costs and attorneys' fees) which may become subject to indemnification under paragraphs (1) through (6) above, but only in accordance with the provisions as stated in paragraph (5) above, and only after the person to receive the payment (i) signs a written affirmation of his good faith belief that he has met the standard of conduct necessary for indemnification under paragraph (4), and (ii) undertakes in writing to repay such advances unless it is ultimately determined that such person is entitled to indemnification by the corporation. The written undertaking required by this paragraph must be an unlimited general obligation of the director but need not be secured. It may be accepted without reference to financial ability to make repayment. (8) The indemnification provided by paragraphs (1) through (6) above will not be exclusive of any other rights to which a person may be entitled by law, bylaw, agreement, vote of shareholders or disinterested directors, or otherwise. (9) Indemnification and advance payment provided by paragraphs (1) through (7) above will continue as to a person who has ceased to hold a position named in paragraph (1) above and will inure to such person's heirs, executors, and administrators. (10) The corporation may purchase and maintain insurance on behalf of any person who holds or has held any position named in paragraph (1) above against any liability incurred by such person in any such position, or arising out of such person's status as such, whether or not the corporation would have power to indemnify such person against such liability under paragraphs (1) through (7) above. (11) Indemnification payments and advance payments made under paragraphs (1) through (10) above are to be reported in writing to the shareholders of the corporation in the next notice or waiver of notice of annual meeting, or within twelve months, whichever is sooner. c.

The affirmative vote of the holders of eighty percent (80%) or more of the issued and outstanding shares of the Corporation at a duly called meeting of the stockholders shall be required for the approval or authorization of (1) any merger or consolidation of the Corporation with or into another corporation or entity, or (2) any sale of all or substantially all of the Corporation's assets to another corporation or entity. g. Consideration of Fairness of Business Combinations. The Board of Directors of the Corporation, when evaluating any offer of another party to (1) purchase or otherwise acquire all or substantially all of the properties or assets of the Corporation, (2) merge or consolidate the Corporation with or into another corporation or entity, or (3) make a tender or exchange offer for any equity security of the Corporation, may, in connection with the exercise of its judgment in determining what is in the best interests of the Corporation and its shareholders, give due consideration to all relevant factors, including, without limitation: (a) the fairness of the price or financial terms of the proposal, (b) the relationship of the proposal to the value of the Corporation in a transaction of a similar type resulting from arm's length negotiations; and (c) the social and economic effects of the proposed transaction on the employees, shareholders and other constituents of the Corporation and on the communities in which the Corporation operates or is located. h. Number and Classification of Directors. The Board of Directors shall consist of not less than three (3) nor more than nine (9) directors. The number of Directors may be increased or decreased (within the limits stated above) by resolution of the Board of Directors, but no decrease may have the effect of shortening the term of any incumbent director. A director may be removed prior to the end of the term for which he is elected only for cause and by the affirmative vote of the holders of eighty percent (80%) or more of the issued and outstanding shares of the Corporation at a meeting of the stockholders duly called for the consideration of such removal. At any such time as the Board of Directors shall consist of nine (9) directors, the Board of Directors may by resolution classify the Board into three (3) classes, each class to consist of three (3) directors. The term of office of directors of the first class shall expire at the first annual meeting of shareholders after their election, that of the second class shall expire at the second annual meeting after their election, and that of the third class shall expire at the third annual meeting after their election. At each annual meeting after such classification the number of directors equal to the number of the class whose term expires at the time of such meeting shall be elected to hold office until the third succeeding annual meeting. i. Supermajority Vote for Amendment of this Article. The provisions set forth in this Article 7 may not be amended, altered, changed or repealed in any respect unless such action is approved by the affirmative vote of the holders of eighty percent (80%) or more of the issued and outstanding shares of the corporation at a meeting of the stockholders duly called for the consideration of such amendment, alteration, change or repeal. j. Limitation of Liability. No director of the corporation shall be personally liable to the corporation or its shareholders for monetary damages for an act or omission in the director's capacity as a director, except that this paragraph does not eliminate or limit the liability of a director for (1) breach of a director's duty of loyalty to the corporation, (2) an act or omission not in good faith or that involves intentional misconduct or a knowing violation of the law, (3) a transaction from which a director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office, (4) an act or omission for which the liability of a director is expressly provided for by statute, or (5) an act related to an unlawful corporate distribution. Neither the amendment nor repeal of this paragraph shall eliminate or reduce the effect of this paragraph in respect of any matter occurring, or any cause of action, suit or claim that, but for this paragraph, would accrue or arise, prior to such amendment or repeal. If the Texas Business Corporation Act or the Texas Miscellaneous Corporation Laws Act is hereinafter amended to authorize corporate action further eliminating or limiting their personal liability of directors, then the liability of a director of the corporation shall be eliminated or limited to the fullest extent permitted by the Texas Business Corporation Act or the Texas Miscellaneous Corporation Laws Act, as so amended from time to time. 8.

This is AMENDMENT NO. 1 TO THE 1993 STOCK OPTION PLAN (the "Plan") of TGC Industries, Inc., a Texas corporation (hereinafter referred to as the "Company"), under which incentive and non-statutory stock options may be granted to the officers, employees, and/or directors of the Company and/or its subsidiaries (now existing or hereafter acquired). Article VIII of the Plan provides that the Company's Board of Directors may at any time amend the Plan, insofar as permitted by law. The purpose of this Amendment No. 1 is to enable holders of options under the Plan to have the maximum period permissible for exercising their options following the termination of their employment "without cause" from the Company or one of its affiliates. Accordingly, the following change is hereby made to the Plan: Sec. 6:4 of the Plan is hereby amended by inserting the words "three (3) months" in substitution for the words "thirty [30] days" in the fifth line from the bottom of Sec. 6:4.A.1.c. This Amendment No.1 to the 1993 Stock Option Plan is dated to be effective July 24, 1996. /S/ WILLIAM J. BARRETT __________________________________ William J. Barrett, Secretary ATTEST: /S/ ROBERT J. CAMPBELL ___________________________________ Robert J. Campbell, Vice Chairman of the Board EXHIBIT 10.10 Amendment No. 2 to 1993 Stock Option Plan of TGC Industries, Inc. On June 3, 1993, the Board of Directors of TGC Industries, Inc. (the "Company") approved and adopted the Company's 1993 Stock Option Plan (the "Plan"). At the 1994 annual meeting of shareholders, the Company's shareholders approved the 1993 Stock Option Plan. Sec. 2:1. of the Plan provides that the aggregate number of shares of Stock to be issued pursuant to the exercise of all Options granted under the Plan may equal, but may not exceed, 750,000 shares of the Company's Stock. Article VIII of the Plan permits the Board of Directors to amend the Plan; provided, however, that, without the approval of the holders of a majority of the outstanding shares of voting stock of all classes of the Company, no such amendment may change the number of shares of Stock subject to the Plan. The purpose of the Plan is to provide an incentive for key employees of the Company to remain in the service of the Company and to apply their best efforts for the benefit of the Company so as to continually improve the Company's financial performance. However, as of the date of this Amendment, options have already been granted under the Plan which cover nearly all of the 750,000 shares of Company Stock initially authorized under the Plan. In order to provide the possibility for the grant of additional options under the Plan so as to promote the incentives referred to above, the Board of Directors has determined that the Plan should be amended so as to permit the issuance of additional shares of the Company's Stock pursuant to options granted under the Plan. Accordingly, Sec. 2:1. of the Plan is hereby amended so as to replace the figure 750,000 with the figure 850,000. This Amendment shall not be deemed to have become effective unless and until the necessary shareholder ratification of such Amendment is given by the shareholders of the Company at their annual meeting to be held on June 4, 1998. IN WITNESS WHEREOF, TGC Industries, Inc., acting by and through its officers thereunto duly authorized, has executed this instrument to be effective June 5, 1998. TGC INDUSTRIES, INC. By:/S/ ALLEN T.
