(1)  This Registration Statement relates to a total of 737,174 Warrants to
     be offered for sale by certain selling security holders.  These
     Warrants were issued as a component of equity units issued by the
     Company in a private placement that closed in September, 1995.  Each
     Warrant is  exercisable to purchase one share of Common Stock at $.375
     per share.  A market currently does not exist for any of the Warrants.

(2)  No registration fee is due for the Warrants under Rule 457(g) because
     this Registration Statement also relates to the Common Stock
     underlying the Warrants.

(3)  This Registration Statement relates to the 887,174 shares of Common
     Stock issuable upon the exercise of all of the following outstanding
     Warrants of the Company: (1) 737,174 Warrants, which are exercisable
     to purchase one share of Common Stock at $.375 per share, issued as a
     component of equity units issued by the Company in the private
     placement that closed in September, 1995 and (2) 150,000 Warrants,
     which are exercisable to purchase one share of Common Stock at $.80
     per share, issued, together with notes, to certain officers and
     directors of the Company in connection with loans to the Company.  

(4)  (a)  These shares are issuable upon the exercise of Warrants at $.375
     per share.

     (b)  These shares are issuable upon the exercise of Warrants at $.80
     per share.

(5)  These shares of Preferred Stock were issued by the Company in a
     private placement that closed in July, 1996.  This Registration
     Statement relates to the shares of Preferred Stock to be offered for
     sale by certain selling security holders.  No market currently exists
     for the Preferred Stock.  A registration fee is not due for the
     Preferred Stock because this Registration Statement also relates to
     the Common Stock underlying the Preferred Stock.

(6)  The Preferred Stock is convertible into shares of Common Stock at the
     following conversion rates (subject to adjustment): (1) prior to the

                                                                  Page iii

     per share of Common Stock of One Dollar and Twenty-Five Cents ($1.25);
     and (3) thereafter, at the conversion price per share of Common Stock
     of Two Dollars ($2.00).  This Registration Statement relates to the
     7,669,000 shares of Common Stock issuable upon the conversion of the

     price.  

(7)  This Registration Statement relates to the Common Stock to be offered

     issued by the Company in a private placement that closed in September,
     1995 and shares issued by the Company upon the exercise by a holder of
     warrants issued in that private placement.  131,332 of these shares
     relate to shares previously issued by the Company upon the exercise of
     certain options granted by the Company to certain officers and
     directors and 12,000 of these shares relate to shares issued in lieu
     of a sales bonus to a former employee of Chase Packaging Corporation,
     formerly a wholly-owned subsidiary of the Company.

     457(c). The average high and low prices as reported on the
     consolidating reporting system as of September 9, 1996, was $1.00.


The Registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrant
shall file a further amendment which specifically states that this
Registration Statement shall thereafter become effective in accordance with
Section 8(a) of the Securities Act of 1933 or until the Registration
Statement shall become effective on such date as the Commission, acting
pursuant to said Section 8(a), may determine.

closed in September, 1995.  Each such Warrant is exercisable for the
purchase of one share of Common Stock for a period of three years at $.375

to which this Prospectus relates were issued at $5.00 per share in a
private placement of TGC that closed in July, 1996 and are convertible into
shares of Common Stock at the following conversion  rates: (1) prior to the
close of business on July 1, 1998 at the conversion price per share of

Common Stock issued in the private placement of the Company that closed in
September, 1995 and the offer for sale by a certain selling security holder
of 10,000 shares obtained by exercising warrants issued in the 1995 private
placement.  Furthermore, this Prospectus relates to 131,332 shares of
Common Stock obtained through exercising certain options granted by the

                                                                  Page v
Company to certain officers and directors, and the offer for sale by a
former employee of Chase Packaging Corporation ("Chase"), formerly a
wholly-owned subsidiary of TGC, of 12,000 shares of Common Stock of TGC
received in lieu of a bonus for past services rendered.

PURCHASERS SHOULD CAREFULLY CONSIDER THE MATTERS SET FORTH UNDER 
"RISK FACTORS" (PAGES 6 THROUGH 13).

No market currently exists for the Warrants or Preferred Stock.  The
Company anticipates that the Warrants and Preferred Stock will be listed on
the NASDAQ SmallCap Market; however, no assurance can be given that such
listing will be effected or that a market will develop.  The Common Stock
is traded on the NASDAQ SmallCap Market under the symbol "TGCI."  On
September 9, 1996, the average of the high and low prices reported in the
consolidated reporting system for the Common Stock was $1.00.  The Company
has been advised that sales by the Selling Security Holders of Warrants and
shares of Preferred Stock and Common Stock may be made from time to time by
or for the account of the Selling Security Holders in the over-the-counter
market, in private transactions, or, otherwise, through broker dealers. 
These sales will be made either at market prices prevailing at the time of
the sale or at negotiated prices.  The broker dealers may act as agents for
the Selling Security Holders or may purchase any of the securities as
principal and thereafter sell such securities from time to time in the
over-the-counter market or otherwise at prices prevailing at the time of
sale or at negotiated prices.  Broker dealers used by the Selling Security
Holders may be deemed to be "underwriters" as defined in the Securities Act
of 1933.  In addition, the Selling Security Holders may be deemed to be
underwriters within the meaning of the Securities Act of 1933 with respect
to the securities offered thereby.      

No person is authorized to give any information or to make any
representations other than those contained in this Prospectus in connection
with the offer contained herein and, if given or made, such information or
representations must not be relied upon as having been authorized by the
Company or any Selling Security Holder.  This Prospectus does not
constitute any offer to sell or a solicitation of an offer to buy any 
securities other than the registered securities to which it relates.  This

                                                                  Page vi
Prospectus does not constitute an offer or solicitation by anyone in any
state in which such offer or solicitation is not authorized or in which the
person making such offer or solicitation is not qualified to do so or to
any person to whom it is unlawful to make such offer or solicitation.  This
Prospectus shall not constitute an offer to sell or a solicitation of an
offer to purchase any securities in any jurisdiction in which such
transactions would be unlawful.  The delivery of this Prospectus at any
time does not imply that the information herein is correct as of any time
subsequent to the date hereof.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR
ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

(1)  The Warrants and shares of Preferred Stock offered hereby by Selling
     Security Holders and the shares of Common Stock offered hereby by
     Selling Securities Holders will be offered at either prevailing market
     prices or at negotiated prices; therefore, the price to the public
     cannot be determined at this time.


                                                                  Page vii
(2)  There is no underwriter.  It is anticipated, however, that the broker- 
     dealers engaged by the Selling Security Holders will receive
     commissions or discounts from Selling Security Holders in amounts
     negotiated immediately prior to the sale.  The amount of any such
     commissions, which will be paid by the Selling Security Holders,
     cannot be determined at this time.

(3)  These securities are offered on behalf of Selling Security Holders of
     TGC, and, therefore, no proceeds from the offering of such securities
     will be paid to TGC.  

(4)  Of the 9,456,680 shares of Common Stock to which this Prospectus
     relates, 737,174 shares are issuable upon the exercise of outstanding
     Warrants issued in the 1995 private placement.  Each Warrant is
     exercisable to purchase one share of Common Stock at $.375 per share.
     Assuming all outstanding Warrants are exercised, the Company will
     receive $276,440.25.  An additional 150,000 shares of Common Stock are
     issuable upon the exercise of Warrants issued, together with notes, by
     the Company to certain officers and directors of the Company.  Each
     Warrant is exercisable to purchase one share of Common Stock at $.80
     per share.  Assuming all such warrants are exercised, the Company will
     receive $120,000.00.  Of the remaining 8,569,506 shares of Common
     Stock to which this prospectus relates, the Company will not receive
     proceeds from the 7,669,000 shares issued upon conversion of all the
     Preferred Stock nor will the Company receive proceeds from the 900,506
     shares offered hereby by certain selling security holders.


             The date of this Prospectus is ____________, 1996.

                             PROSPECTUS SUMMARY

The following is a brief summary of certain information contained elsewhere
herein.  This summary does not contain a complete statement of such
information and is qualified in its entirety by reference to, and should be
read in conjunction with, the detailed information and financial statements
incorporated by reference herein and in the exhibits hereto.

The Company

In April, 1980, Supreme Industries, Inc., formerly ESI Industries, Inc.,
("Supreme") formed a wholly-owned subsidiary which acquired certain
equipment, instruments, and related supplies of Tidelands Geophysical Co.,
Inc. ("Tidelands"), a Houston-based corporation which was 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.  On June 24, 1996, the Board of Directors approved the
spin-off of Chase whereby all of the shares of Chase owned by TGC will be
distributed as a stock dividend to the shareholders of the TGC Common Stock
and, on an as if converted basis, the TGC Preferred Stock, effective July
31, 1996.  The record date for the spin-off was July 15, 1996; however, the
TGC Common Stock has traded with "due bills" since the record date and will
continue to do so through the distribution date of the Chase Common Stock,
which date will be the first business day after the Registration Statement
filed with the Securities Exchange Commission with respect to the Chase
Common Stock has been declared effective.  The distribution date is
currently anticipated to occur in October, 1996.

                                                                  Page 2

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 which 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.

Industry Overview

Seismic data is the principal source of information used by geoscientists
to map potential oil and gas bearing formations and the geologic structures
that surround them.  Seismic data is acquired over a wide area by directing
sound waves into the earth and measuring the response as these sound waves
reflect off subsurface geologic formations.  In the past, the 2-D seismic
survey was the standard data acquisition technique used to describe
geologic formations over a broad area.  2-D seismic data can be visualized
as a single vertical plane of subsurface information, and 2-D seismic
surveys typically require 120 recording channels.  Data gathered from a 3-D
seismic survey is best visualized as a cube of information that can be
sliced into numerous planes, providing different views of a geologic
structure with much higher resolution than is available with traditional
2-D seismic survey techniques.  Unlike 2-D seismic surveys, 3-D seismic
surveys require much larger acquisition systems with at least 480 recording
channels.  Moreover, large 3-D surveys increasingly requested by customers
may require 1,500 or more recording channels.  As a result of the more
subtle and complex geologic structures now being explored, 3-D seismic
surveys utilizing  state-of-the-art data acquisition systems increasingly
are conducted in the exploration stage to provide more extensive

                                                                  Page 3
information regarding subsurface geology.  In addition, 3-D surveys are
increasingly used to delineate locations for drilling development wells in
producing basins, as well as for reservoir management activities.

The Company believes that the growth in the use of 3-D seismic surveys will
continue, and that this trend is primarily attributable to:  (i) the
availability of improved technology capable of providing higher quality
data at a lower cost; (ii) the increased acceptance and interest by the
domestic energy industry of 3-D seismic techniques as a viable risk
management tool; and (iii) the success and increased use of 3-D seismic
surveys for field development and reservoir management applications in
addition to exploration activities.  As reported by World Geophysical News
on January 15, 1996, approximately 70% of the land-based seismic crews
working in the United States and Mexico were conducting 3-D seismic
surveys.

Market for Securities . . . . . .   No market currently exists for the
                                    Warrants or the Preferred Stock.  The
                                    Company anticipates that the Warrants
                                    and the Preferred Stock will be listed

                                    "TGCI".  See "Description of
                                    Securities" and "Risk Factors".


                                RISK FACTORS

In addition to the other information set forth in this Prospectus, the
following factors should be carefully reviewed and considered in evaluating
the Company and this offering.

Dependence Upon Energy Industry Spending

Demand for the Company's services depends upon the level of capital
expenditures by oil and gas companies for exploration, production,
development, and field management activities.  These activities depend in
part on oil and gas prices, expectations about future prices, the cost of
exploring for, producing, and delivering oil and gas, the sale and
expiration dates of leases in the United States, the discovery rate of new
oil and gas reserves in land areas, local and international political,
regulatory, and economic conditions, and the ability of oil and gas
companies to obtain capital.  In addition, a decrease in oil and gas
expenditures could result from such factors as unfavorable tax and other
legislation or uncertainty concerning national energy policies.  The oil
and gas energy has been a cyclical business.  The outlook for domestic 3-D
data acquisition services remains positive at this time due to the
capability of this technology to provide higher quality data at a lower
cost, the increased acceptance of 3-D seismic techniques as a viable risk
management tool, and the increased success rates using 3-D surveys for
exploration and development activities.  The improved cost effectiveness
gained from the data acquisition and processing of 3-D surveys has resulted
in increased profits for the U.S. operations of the major and independent
oil and gas companies.  With these cost advantages and the uncertainty of
foreign operators, many of the major U.S. energy companies are increasing
participation in the domestic oil and gas industry.  No assurance can be

                                                                  Page 6
given that current levels of oil and gas activities will be maintained or
that demand for the Company's services will reflect the level of such
activities.  Decreases in oil and gas activities could have a significant
adverse effect upon the demand for the Company's services and the Company's
results of operations.

Risks of Operations

TGC's geophysical division had a small profit before interest and taxes in
1995 and was below expectations.  The 29% increase in revenues for 1995
when compared to 1994 can be attributed to a full year's operation of a
second seismic crew which commenced operations in the 1994 third quarter
when the Company's Sercel 368/348 data acquisition system was placed into
service.  In spite of this revenue increase, profit margins in 1995
decreased substantially due to unusually poor summer weather in the
Mid-Continent region and because several large contracts were canceled by
clients due to lease problems on their 3-D areas of interest, resulting in
interruption of the Company's planned data acquisition schedule.  In
addition, financial results were negatively impacted by a significant
increase in non-cash charges for depreciation ($800,796 for 1995 as
compared to $393,579 for 1994) as a result of the Company's capital
expansion program in the 1994 third quarter.  For the first six months of
1996 as compared to 1995, revenues from continuing operations have
increased $727,475 and operating profit has increased $96,719 over the same
period of 1995.  Earnings per common share, from continuing operations,
were $.04 in the first six months of 1996 as compared to $.03 for the same
period in 1995.  Earnings before interest, taxes, depreciation, and
amortization (EBITDA) was $.11 per common share for 1996 and 1995 for the
time period mentioned above.  Historically, the Company has been
geographically concentrated in the Mid-Continent region of the United
States.  Currently, the Company services the Mid-Continent and West Coast
regions.

With the recent purchase and delivery of the Opseis 24-Bit Eagle Recording
System, the Company anticipates the demand for its services will increase. 
The geophysical operation has an improved backlog into the second half of
1996 and management anticipates a continuation of favorable revenue trends.

                                                                  Page 7
The additional backlog in the second half of 1996 is due to the purchase
and delivery of the 24-Bit Eagle System.  The Eagle crew began production
the first part of August, 1996.  As a result of the expanded recording
capabilities and current backlog for the Company, management anticipates a
continuation of improved revenues and profit margins for the remainder of
1996.  If such financial results are realized, management anticipates an
additional upgrading of the existing equipment through the purchase of a
second Eagle System or other equipment during the next twelve months.  A
degree of risk is inherent in the Company's operations, however, due to
possible downtime from adverse weather conditions and the nature of the
Company's turnkey contracts which are subject to the risk of delay or
cancellation.  With the unpredictable nature of forecasting weather and
with the potential for contract delay or cancellations, no assurance can be
given that management's expectations can be achieved.

Public Market for Securities

Warrants

No public market currently exists for the Warrants offered hereby.  The
Company anticipates that the Warrants will trade on the NASDAQ SmallCap
Market.  However, no assurance can be given that this will occur.  If the
Warrants are not listed on the NASDAQ SmallCap Market, the Company
anticipates that the Warrants will trade in the over-the-counter market and
will be quoted on the OTC Bulletin Board. No assurance can be given that an
active and liquid market will develop in the Company's Warrants.

Preferred Stock

No public market currently exists for the Preferred Stock offered hereby. 
The Company anticipates that the Preferred Stock will trade on the NASDAQ
SmallCap Market.  However, no assurance can be given that this will occur. 
If the Preferred Stock is not listed on the NASDAQ SmallCap Market, the
Company anticipates that the Preferred Stock will trade in the over-the-
counter market and will be quoted on the OTC Bulletin Board. No assurance
can be given that an active and liquid market will develop in the Company's
Preferred Stock.

                                                                  Page 8

Common Stock

The Company's Common Stock has been traded under the symbol "TGCI" since
October 31, 1986.  From October 31, 1986 to September 22, 1994, the stock
traded in the over-the-counter market with quotations available in the
National Daily Quotation Source's "Pink Sheets" or on the "OTC Bulletin
Board" of the National Association of Securities Dealers.  Effective
September 25, 1994, TGC's Common Stock began trading on the NASDAQ SmallCap
Market under the same symbol "TGCI".  The number of shareholders of record
of TGC's Common Stock as of July 31, 1996 was 444.  The Company believes
that there is a significantly greater number of beneficial owners of its
Common Stock.  Although the Company has two market makers for its Common
Stock, trading in shares of the Common Stock is extremely light.  As a
result, no assurance can be given as to the ability of a holder to readily
liquidate such holder's shares of Common Stock in the Company.  The Company
has never paid dividends on its Common Stock and has no plans to do so in
the future.     

Competition   

The land-based seismic data acquisition business is highly competitive. 
The Company believes that it has approximately 20 competitors in the United
States.  Competitive factors include price, crew experience, equipment
availability, technological expertise, and reputation for dependability. 
Certain of the Company's major competitors operate more data acquisition
crews than the Company, provide integrated data acquisition, processing and
interpretation services, have substantially greater revenues than the
Company, and are subsidiaries or divisions of major industrial enterprises
having far greater financial and other resources than the Company and more
extensive relationships with major integrated and multinational oil and gas
companies.  Such resources enable these competitors to maintain
state-of-the-art technology and certain other advantages relating to costs
that may provide them with an advantage over the Company in bidding for
contracts.  In addition, certain competitors of the Company take an
economic interest in oil and gas exploration and development projects for
which they perform services for their customers.  There can be no assurance
that the Company will be able to compete successfully against its

                                                                  Page 9
competitors for contracts to conduct seismic surveys.  See "Business of the
Company."

Capital Intensive Business; Rapid Obsolescence of Technology

The Company competes in a capital intensive industry.  The development of
seismic data acquisition equipment has been characterized by rapid
technological advancements in recent years and the company expects this
trend to continue.  There can be no assurance that manufacturers of seismic
equipment will not develop new systems that have competitive advantages
over systems now in use that could either render the Company's current
equipment obsolete or require the Company to make significant capital
expenditures to maintain its competitive position.  The Company's strategy
is to upgrade its data acquisition systems as often as necessary to
maintain its competitive position.  However, to do so may require large
expenditures of capital which the Company may be unable to accomplish.  See
"Business of the Company."

Operating Risks; Weather

The Company's crews often conduct operations in extreme weather, in
difficult terrain that is not easily accessible, and under other hazardous
conditions.  Accordingly, its operations are subject to risks of injury to
personnel and loss of equipment.  As a result, low productivity resulting
from weather interruptions, equipment failures, or other causes, such as
fires and accidental explosions resulting from the handling of equipment
and supplies, can result in significant operating losses.  In addition,
while the Company has insurance policies that protect it against
liabilities that may be incurred in the ordinary course of its business,
the Company is unable to insure fully against all possible loss or
liability.  See "Business of the Company -- Operating Conditions."

Hazardous Operations

The Company's geophysical services business is subject to certain hazards,
including damage to equipment and injury to persons from explosives used in
land seismic operations.  The Company carries insurance on its equipment

                                                                  Page 10
and personnel in amounts which it considers adequate.  

Classification of the Board of Directors

The Company's Articles of Incorporation and Bylaws provide authorization
for dividing the Board of Directors into three separate classes having
staggered terms so that only one-third of the total number of Directors is
up for election at each annual meeting of the shareholders of the Company. 
The Company's Articles of Incorporation also provide that the provision
authorizing such a classification of the Board of Directors 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 at a meeting called for such
purpose.  At the present time, the Company does not anticipate that a
classification of the Board of Directors into three separate classes with
each class having a staggered term, as provided above, will be placed into
effect.  See "Description of Securities."

Reliance on Key Personnel

The Company's operations are dependent on the efforts of its Vice-Chairman
and Chief Executive Officer, Robert Campbell and its President, Wayne
Whitener.  If any of these key persons becomes unable to continue in his
present role, or if the Company is unable to attract and retain other
skilled employees, the Company's business could be adversely affected.

Dependence on Major Customers

During the fiscal year ended December 31, 1995, the two largest customers
of TGC's geophysical operations accounted for approximately 21% and 12%,
respectively, of the sales of the geophysical operations.  The loss or
significant reduction of business from either of these customers may have a
material adverse effect on the Company.  See "Business of the Company."

Environmental Regulations

Many of the Company's operations are affected by federal, state, and local

                                                                  Page 11
environmental regulations that could potentially be interrupted or
terminated on the basis of environmental or other considerations. 
Moreover, the Company is potentially subject to significant financial
penalties if it violates such regulations.  Attempt at compliance with such
regulations may affect the Company's operations and may necessitate
significant capital outlays.  See "Business of the Company."

Potential Increase In Shares of Common Stock Outstanding

As of July 31, 1996, there were 6,188,018 shares of the Company's Common
Stock outstanding.  Certain Warrants of TGC are exercisable for the
purchase of one share of Common Stock at $.375 per share of Common Stock. 
An additional 737,174 shares of the Company's Common Stock are issuable
upon the exercise of the Warrants, assuming all outstanding Warrants are
exercised.  Additional warrants of TGC are exercisable at $.80 per share of
Common Stock.  An additional 150,000 shares of Common Stock are issuable
upon the exercise of such warrants.

The Series C 8% Convertible Exchangeable Preferred Stock at $5.00 per share
is convertible into Common Stock of the Company at the initial conversion
price per share of Common Stock of $.75, until July 1, 1998.  An additional
7,669,000 shares of the Company's Common Stock are issuable upon the
conversion of the Preferred Stock offered hereby, or, if exchanged by the
Company, the 8% Subordinated Convertible Debentures, Series A, assuming
conversion at the lowest conversion price per share of $0.75 per share of
Common Stock. 

In addition, shares of the Company's Common Stock are reserved for issuance
upon exercise of outstanding stock options under the Company's Incentive
and Nonqualified Stock Option Plan.  An additional 51,668 shares are
reserved for issuance upon exercise of outstanding stock options under the
Company's 1986 Stock Option Plan and an additional 625,000 shares are
reserved for issuance upon exercise of outstanding stock options under the
Company's 1993 Stock Option Plan.  Such shares may, in the future, be
issued and become available for sale in the public market.  See "Market for
the Company's Common Stock and Related Stockholder Matters."   

                                                                  Page 12

Future Sales of Outstanding Shares of Common Stock

Future sales of shares of Common Stock could adversely affect the
prevailing market price of the Company's Common Stock.  As of July 31,
1996, there were 6,188,018 shares of the Company's Common Stock
outstanding.  Of such shares, 3,068,750 shares of Common Stock were issued
in private placements in July and August, 1993, and an additional 1,530,000
shares of Common Stock were issued pursuant to conversions of the Company's
Series A and B Preferred Stock in July, 1994 and may be sold into the
public market under Rule 144.  

No prediction can be made as to the effect, if any, that market sales of
shares of Common Stock or the availability of such shares for sale will
have on the market prices prevailing from time to time.  Nevertheless, the
possibility that substantial amounts of Common Stock may be sold in the
public market may adversely affect prevailing market prices for the Common
Stock and could impair the Company's ability to raise capital through the
sale of its equity securities.  See "Description of Securities."


                               USE OF PROCEEDS

Certain warrants of the Company are exercisable for $.375 per share.  The
Company will receive up to $276,440.25 if all of the holders of such
warrants exercise the warrants.  Certain other warrants are exercisable at
$.80 per share.  The Company will receive $120,000.00 if the holders of
such warrants exercise such warrants.  The Company intends to use any
proceeds received from the exercise of the warrants for working capital. 
The issuance of shares of Common Stock offered hereby upon conversion of
the outstanding shares of Preferred Stock  will not result in any proceeds
being received by the Company.  In addition, the exchange, if any, of
Debentures for Preferred Stock will not result in any proceeds being
received by the Company.  Because the remainder of the offering to which
this Prospectus relates is being effected on behalf of selling security
holders of the Company, no proceeds from such offering will be received by
the Company.  The amount of net proceeds to be received by the selling

                           BUSINESS OF THE COMPANY

TGC Industries, Inc., a Texas corporation (the "Company" or "TGC"), was
formed in April, 1980, as a wholly-owned subsidiary of Supreme Industries,
Inc., formerly ESI Industries, Inc., ("Supreme"), which acquired certain
equipment, instruments and related supplies of Tidelands Geophysical Co.,
Inc. ("Tidelands"), a Houston-based corporation which 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.  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. 
On June 24, 1996, the Board of Directors of TGC approved the spin-off of
Chase whereby all of the shares of Chase owned by TGC will 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
record date for the spin-off was July 15, 1996; however, the TGC Common
Stock has traded with "due bills" since the record date and will continue
to do so through the distribution date of the Chase Common Stock, which
date will be the first business day after the effectiveness of the
Registration Statement that the Company intends to file with the Securities
& Exchange Commission.  The distribution date is currently anticipated to
occur in October, 1996.  

Since its formation TGC has engaged in the domestic geophysical services

                                                                  Page 14
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 which 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.  The Company's seismic crew uses dynamite as the primary energy
source for such surveys. The Company has also developed three-dimensional
("3-D") recording capabilities that give the Company's crews the ability to
acquire a very dense grid of seismic data over a precisely defined area. 
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.

Business Strategy

The Company's objective is to become one of the leading providers of
land-based 3-D seismic acquisition services to the oil and gas industry in
the United States.  The Company intends to reach this objective through the
implementation of business strategies which include:

Upgrading its operation to state-of-the-art data acquisition systems -- The
Company intends to further upgrade its equipment for performing 3-D seismic
surveys on land.  The Company recently acquired one Opseis Eagle recording
system, with a capacity of approximately 1,500 channels, by using a portion
of the proceeds from the private placement that closed in July, 1996,
together with bank financing.  The Company intends to acquire a second
system to be operational in approximately twelve months if market
conditions in the industry permit and funds for such acquisition are
available for the addition of the second system.

                                                                  Page 15

Optimizing equipment utilization -- The Company will seek to optimize
equipment utilization by relocating data acquisition systems among regions
to respond to regional and seasonal demand patterns.

Capitalizing on the strong reputation of the Company and its key executives
- -- TGC is an old-line, well respected seismic survey company with a
reputation for providing high quality seismic services to a broad range of
domestic exploration companies.  The Company plans to aggressively
capitalize on these factors.

Expanding operations through strategic acquisitions -- The Company will
seek to acquire other land-based seismic data acquisition businesses that
complement the Company's geographic market coverage and further the
Company's strategy for growth.  TGC periodically evaluates opportunities to
acquire businesses and assets; however, the Company does not have any
current understanding, arrangement, or agreement to acquire any such
businesses or assets.

No assurance can be given that the Company's strategy will be successful.
See "Risk Factors" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations".

Seismic Technology

Seismic data is acquired with the use of an energy source such as dynamite. 
The energy sources are discharged at or below the earth's surface,
producing acoustic waves which travel toward the center of the earth and
are reflected back to the surface depending upon the variations in the
underlying rock layers.  The reflected acoustic waves are detected by
sound-sensitive devices called "geophones," which are situated at intervals
along specified paths at varying distances from the energy source. 
Specialized seismic processing systems enhance recorded signals by reducing
distortion and improving resolution.  Seismic data, once recorded, is
processed using sophisticated computer software programs and arranged to
produce an image of the earth's substructure.  By interpreting seismic
data, geophysicists are able to create detailed maps of either prospective
drilling areas or of known oil and gas reservoirs.

                                                                  Page 16

Seismic Data Acquisition Services

TGC is engaged in land-based seismic data acquisition on a contract basis
for its customers and not for its own account.  When the Company is asked
to formulate a proposal to acquire seismic data on a customer's behalf, the
Company's geophysicists work with the customer in designing the
specifications of the proposed survey and, once the specifications are
agreed upon, the survey is taken to the field where one or more of the
Company's crews commence the process of acquiring data.

A seismic crew typically consists of permitting agents who secure
permission to enter a landowner's property, surveyors who mark the
locations for the placement of geophones and other equipment, general
laborers who place and move the geophones and other equipment, a drill crew
to drill holes and shooters to detonate the dynamite, and an observer who
operates the central electronics unit and controls the recording of the
seismic data.  A fully staffed 3-D seismic crew in the United States
typically has from 20 to 50 personnel conducting 3-D seismic surveys,
depending upon the size and nature of the survey required by the customer. 
Vehicles assigned to each crew consist of a recording truck, two or more
cable and geophone trucks, a dynamite truck and several personnel vehicles
with off-road capability.

The Company's crews are equipped with a minimum of 1,200 channel seismic
recording instruments, geophones and a variety of other seismic equipment. 
The Company believes that its customers will increasingly demand 3-D
seismic surveys.

The Company will seek to optimize equipment utilization by relocating data
acquisition systems among regions to respond to regional and seasonal
demand patterns. The following is a summary of the Company's current
technological seismic equipment:

                  Existing Capabilities and Crew Locations

                                      
                                  Crew 310

                                                                  Page 17

   This crew was recently equipped with an OPSEIS 24-BIT EAGLE Recording
   System capable of recording 1500 channels of seismic data at a 2MS
   sample rate.  This crew is State-of-the-Art and allows for diverse and
   cost effective 3-D operation.  Most of this crew's work has been in the
   Gulf Coast and Mid-Continent areas.  The primary clients for this crew
   are major and large to mid-sized independent companies.

                                  Crew 330

   This crew is equipped with an Opseis 5586 radio telemetry system
   capable of recording 1200 channels of seismic data at a 2MS sample
   rate.  The flexibility of this crew to overcome logistical problems in
   difficult areas is a major plus in the acquisition of 3-D programs. 
   This crew has been working mainly in the state of California for
   independent oil companies.


Seismic Data Processing

The processing of seismic data involves the conversion of such data, by
means of sophisticated computer software designed for this purpose, into
graphic representations of cross-sections of the earth's subsurface.
Because of the specialized computer technology required, the digital
seismic tapes acquired by the Company from its digital seismic surveys are
transmitted by the Company to data processing centers (not owned or
operated by the Company) designated by the customers 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.  The Company does not have a seismic data bank. 
Data Bank information has been amassed through participatory surveys as
well as speculative surveys funded by the Company alone.  All data and
interpretations may be licensed to customers at a fraction of the cost of
newly-acquired data.  At the present time, the company is experiencing low
sales in this area.

Operating Conditions

                                                                  Page 18

The Company's seismic data acquisition operations historically have been
subject to seasonal fluctuations, with the greatest volume of data
acquisition occurring during the  summer and fall in the northern
hemisphere.  The Company may conduct operations year round with fewer days
of down-time caused by inclement weather by working during the favorable
operating seasons of different regions.  The Company believes that by
increasing the geographical scope of its operations, the impact on the
Company of seasonal fluctuations may be reduced.


Marketing and Customers

I.   Marketing -- The Company's services traditionally have been marketed
     by the principal executive officers and marketing representatives.

II.   Contracts -- The Company provides its services to customers pursuant
      to contracts the terms of which are occasionally varied or modified
      by mutual consent.  In many instances, such contracts are cancelable
      by the customer on short notice without penalty.  Contracts are
      obtained by the Company either through competitive bidding, in
      response to invitations for bids, or by direct negotiation with a
      prospective customer.

Most frequently, customers invite bidders to provide quotations on the cost 
to gather seismic data over a specified region within a specified period of 
time.  Some customers, primarily large oil companies, require at least
three  bids in order to award a contract.  Contracts are awarded primarily
on the  basis of price, crew experience and equipment technology and
reputation for dependability.  

Contract terms, whether bid or negotiated, generally provide for payment by 
the customer on either a "turnkey" or a "term" basis or on a combination of 
both methods.  Under the turnkey method, payments for data acquisition 
services are based upon a fixed fee for each unit of data collected, and
the  Company bears substantially all of the risk of business interruption
due to  inclement weather and other hazards.  Term contracts, on the other
hand,  provide for payment based on agreed rates per unit of time, which

                                                                  Page 19
may be  expressed in periods ranging from days to months, and most of the
risk of  business interruption (except for interruptions caused by failure
of the  Company's equipment) is borne by the customer.  When a combination
of  turnkey and term methods is used, the risk of business interruption is 
shared in an agreed percentage by the Company and the customer.  In each 
case, progress payments are usually required unless it is anticipated that 
the job will be completed in less than 30 days.  The majority of the 
Company's recent contracts for data acquisition have been on a turnkey
basis.

The Company's contracts specify that the seismic data acquired by the 
Company belongs to the Company's customer, and the Company does not acquire 
any seismic data for its own account.  All of the customer's information is 
maintained in confidence.

III.  Customers -- The Company's customers include and have included a
      number of major oil companies including Marathon Oil Company and
      Texaco, as well as many smaller, independent oil and gas operators.

 A large portion of the net sales of the Company in any period may be
 attributable to a limited number of customers, even though the mix of
 customers changes over time as contracts are awarded and completed.  The
 Company has a number of customers for which, over the years, services have
 been repeatedly provided.

IV.   Safety Program -- Certain of the Company's customers require, as a
      condition of awarding contracts, that a safety program designed to
      reduce the hazards associated with the seismic data acquisition
      business be in place.

V.   Backlog -- At March 1, 1996, the Company's backlog of commitments for
     data acquisition services was approximately $4.3 million, increasing
     to approximately $7.1 million at August 1, 1996.  The increase in
     backlog is primarily attributable to taking delivery in late July of
     the OPSEIS EAGLE System. The majority of such backlog consisted of
     written contracts or commitments; however, contracts for services are
     occasionally varied or modified by mutual consent and, in many

                                                                  Page 20
     instances, are cancelable by the customer on short notice without
     penalty.  Consequently, the Company's backlog as of any particular
     date may not be indicative of the Company's actual operating results
     for any succeeding fiscal period.  Subject to the foregoing, the
     Company anticipates that substantially all the contracts and
     commitments included in backlog at August 1, 1996 will be completed
     prior to the end of 1996.

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, other than dynamite, which the Geophysical operations
obtains from several different suppliers.

The Company utilizes 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 customers.  The present client
base consists of major oil companies and mid-size to small independent oil
and gas producers.  With the recent addition of the EAGLE System, TGC, with
this new equipment and technology, should be able to expand its current
markets and clients.  For the year end December 31, 1995, the Company
generated twenty-one (21%) of its revenues from contracts with Marathon Oil
Company and twelve percent (12%) of its revenues from Slawson Exploration
Company.  Management does not believe that the Company has any other
material customers at the present time.  The Company enters into a general
or master agreement with each of its customers 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 customer.  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 customers 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.

                                                                  Page 21

Activity in the U.S. Geophysical Industry has 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 has 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 are increasing
participation in the domestic oil industry.

Due to the Company's marketing efforts, it has been able to establish a new
West Coast market for one of its geophysical crews.  The other crew is
working in the Mid-Continent and the Gulf Coast regions.  With the addition
of this new market area, the Company should see an increase in revenues and
operating profits.  However, due to uncertainties related to weather,
permits, and oil and gas prices, there can be no assurance that such
improvement in revenues and operating profits can be achieved.

Regulation

Seismic data acquisition operations are subject to various laws and
regulations. Such laws and regulations govern various aspects of
operations, including the discharge of explosive materials into the
environment, requiring removal and cleanup of materials that may harm the
environment or otherwise relating to the protection of the environment,
access to private and governmental land to conduct seismic surveys and use
of local employees and suppliers by foreign contractors.  The Company
believes that it has conducted its operations in substantial compliance
with applicable environmental laws and regulations governing its
activities.

Employees

As of July 31, 1996, the geophysical operation of TGC employed
approximately 66 people of whom 3 performed management and marketing
functions, 3 performed administrative services or clerical functions, 4
were geophysicists or rendered engineering or other technical services and
approximately 56 were members of the Company's seismic crews or performed
other operations.  None of the Company's employees is represented by a

                                                                  Page 22
labor union or a direct or indirect party to a collective bargaining
agreement.  The Company believes it has good relations with its employees.


                           PROPERTY OF THE COMPANY

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/warehouse space and an outdoor storage
area of approximately 10,000 square feet.  The monthly rent is $3,860. 
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.

In July, 1996 the Company acquired the Portland, Oregon facility from the
liquidation of the Company's wholly owned subsidiary, Chase Packaging
Corporation.  The facility is 88,000 square feet of office and
manufacturing space with outdoor resin silos and a parking lot.  Chase had
previously acquired the facility when Chase purchased certain assets of
Union Camp Corporation's packaging division in July, 1993.  The Company is
currently holding the facility for sale, and the proceeds from the sale of
the Portland, Oregon facility will be contributed to Chase to be applied
against the mortgage indebtedness currently encumbering such facility.  


        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
                         AND RESULTS OF OPERATIONS

Results of Continuing Operations

Three Months and Six Months Ended June 30, 1996 Compared To 
The Three Months and Six Months Ended June 30, 1995

Revenue increased to $2,225,255 for the three months ended June 30, 1996
compared to revenue of $1,782,067 for the same period of 1995.  Revenue for
the first six months of 1996 was $4,459,927, a 19% increase from revenue of
$3,732,452 for the first six months of 1995.  The increase in revenue was

                                                                  Page 23
the result of a diversified backlog which included seismic surveys with
higher contract prices in 1996 when compared to the Company's 1995 program.
Operating profit before interest and taxes was $64,430 for the 1996 second
quarter as compared to operating profit before interest and taxes of
$84,193 for the second quarter of 1995. Operating profit before interest
and taxes for the six months ended June 30, 1996 was $285,940 as compared
to operating profit before interest and taxes of $184,494 for the same
period of 1995.  Although profit margins for the 1996 second quarter were
down due to start-up costs on a seismic contract, timely preparation of
seismic program improved the crew's recording efficiencies, resulting in
increased operating margins for the first six months of 1996 when compared
to the same period of 1995.

One of TGC's seismic crews worked in the Gulf Coast during the 1996 second
quarter.  TGC's second seismic crew continued work in California (a new
market for the Company) during this same period.  With minimal interruption
of the Company's planned data - acquisition schedules, both crews were able
to record sufficient quantities of seismic data in the allotted time
periods.  The increased efficiencies achieved by both recording crews
during the first half of 1996 resulted in improved operating margins and
increased profitability for the geophysical operation when compared to the
first half of 1995.

The outlook for domestic 3-D data acquisition services remains positive at
this time due to the capability of this technology to provide higher
quality data at a lower cost, the increased acceptance of 3-D seismic
techniques as a viable risk management tool and the increased success rates
using 3-D surveys for exploration and development activities.  The improved
cost effectiveness gained from the data acquisition and processing of 3-D
surveys has resulted in increased profits for the U.S. operations of major
and independent oil and gas companies.  With these cost advantages and the
uncertainty of foreign operations, many of the major U.S. energy companies
are increasing participation in the domestic oil and gas industry.  The
Company currently has a backlog that extends into the 1996 fourth quarter
and includes programs in the Gulf Coast and Mid-Continent regions and on
the West Coast.  The backlog includes small and large surveys for major and
independent oil and gas companies.

                                                                  Page 24

In July of 1996, TGC purchased a 24-Bit Opseis Eagle recording system with
1,500 channels and also acquired support equipment (cables and geophones)
for this system.  The purchase of these assets will improve recording
capacity and marketability of TGC's seismic services, enabling the Company
to take advantage of the current favorable environment for domestic
exploration.  TGC used $2,000,000 in proceeds from the July 1996 private
placement of Series C 8% Convertible Exchangeable Preferred Stock
("Preferred Stock"), together with some bank financing, to purchase this
system and support equipment.  As a result of the expanded recording
capabilities and current backlog for the Company, management anticipates a
continuation of improved revenues and profit margins for the remainder of
1996.  However,  a degree of risk is inherent in the Company's operations,
due to possible downtime from adverse weather conditions and the nature of
the Company's turnkey contracts which are subject to the risk of delay or
cancellation.  With the unpredictable nature of forecasting weather and the
potential for contract delay or cancellation, no assurance can be given
that management's expectations can be achieved.


Fiscal Year Ended December 31, 1995 Compared to Fiscal Year Ended December
31, 1994

Revenues for the twelve months ended December 31, 1995 increased 29% to
$7,543,240 from the 1994 annual revenues of $5,867,351.  Operating income
(before interest expense and taxes) was $28,562 for the year ended December
31, 1995 compared to operating income before interest and taxes of $717,068
for the twelve months ended December 31, 1994. Interest expense for the
twelve months ended December 31, 1995 was $52,648 which was attributable to
the financing of equipment additions for seismic operations.

The 29% increase in revenues for 1995 when compared to 1994 can be
attributed to a full year's operation of a second seismic crew which
commenced operations in the 1994 third quarter when the Company's Sercel
368/348 data acquisition system was placed into service.  In spite of this
revenue increase, profit margins in 1995 decreased substantially when
compared to 1994 due to unusually poor summer weather in Texas and
Oklahoma.  Also, several contracts were canceled by clients due to lease

                                                                  Page 25
problems on their 3-D areas of interest, resulting in interruption of the
Company's planned data acquisition schedule.  The ability of TGC's two
crews to record large quantities of data in a short period of time, which
is essential for profitability, was limited by these various problems and
resulted in lower operating margins.  In addition, financial results were
negatively impacted by a significant increase in non-cash charges for
depreciation ($800,796 for 1995 as compared to $393,579 for 1994) as a
result of the Company's capital expansion program in the 1994 third
quarter.

The trend in oil and gas exploration for a number of years has been to
focus on the larger potential of oil and gas fields outside the United
States.  In the past two years more of the Company's clients became
familiar with 3-D surveys and have had discoveries of oil and gas in the
United States using 3-D data.  The result was an increase in domestic
exploration activity from which the Company benefitted in 1994 as one of
the few remaining domestic geophysical contractors.  In 1995, however, the
increased activity has attracted additional geophysical contractors,
primarily from Canada, to the U.S. market.  These additional contractors
created a competitive bidding environment, but with an increased number of
contracts available during 1995, the Company was able to maintain its
revenue base.  However, profit margins were depressed due to TGC's
geographic concentration in the Mid-Continent region which resulted in crew
operations being hampered by unusually poor weather in such region during
1995.  In addition, work slow downs due to contract cancellations (as
previously discussed) in the third quarter contributed to TGC's 1995 profit
margin decline.

The domestic demand for 3-D data acquisition services remains positive at
this time.  A number of major oil and gas companies have experienced a
variety of problems overseas and are increasing their U.S. exploration
budgets.  The Company currently has a backlog for both crews that extends
into the 1996 third quarter and includes program in the Mid-Continent
region and on the West Coast.  The backlog includes small and large surveys
for major and independent oil and gas companies.  The Company generally
works under turnkey contracts which have more profit potential than fixed
term contracts; however, turnkey contracts involve more risk because of the

                                                                  Page 26
potential downtime from unfavorable weather and other types of delay.  With
improvements in existing contracts and advance preparatory work, geographic
diversification into other regions, and with the improved efficiency now
being achieved by the second crew's Sercel 368/348 data gathering system,
management anticipates an increase in revenues and profit margins in 1996. 
Due to competitive forces and the unpredictable nature of forecasting
weather, however, no assurance can be given that management's expectations
can be achieved.  

Financial Condition

Cash of $861,649 was provided by continuing operations for the first six
months of 1996 compared to cash provided by continuing operations of
$836,011 for the first six months of 1995.  The funds generated in the
first half of 1996 were primarily attributable to net earnings before
non-cash depreciation charges for the Company's geophysical operation and
to funds received from advance billings on geophysical contracts.  Cash
used in investing activities for the first six months of 1996 was primarily
for additions to machinery and equipment for geophysical field operations. 
Cash provided by financing activities for the first six months of 1996
consisted of $150,000 advance on proceeds from the private placement of TGC
Preferred Stock, $125,813 in proceeds from subordinated notes issued to an
executive officer of the Company and $3,750 from the issuance of stock,
partially offset by $96,715 in debt principal payments.

The pro forma balance sheet at June 30, 1996 assumes the closing of the
private placement of 8% Convertible Exchangeable Preferred Stock and the
spin-off of Chase Packaging Corporation, formerly New Chase Corporation,
("Chase") was consummated on June 30, 1996.  As a result, stockholder's
equity increased $1,342,213 from the December 31, 1995 balance of
$1,643,127 to $2,985,340.  This increase was primarily due to the closing
of the private placement which resulted in net proceeds of approximately
$4,700,000.  The Company contributed approximately $2,700,000 of the
proceeds as a capital contribution to Chase.  The balance of $2,000,000,
together with bank financing, was used by the Company to purchase a
state-of-the-art geophysical recording system.  The Company placed this
system into service in early August, 1996.  In addition, subordinated debt

                                                                  Page 27
in the amount of $365,813 was converted into 73,162 shares of preferred
stock.  The liquidation of Old Chase resulted in a liability of $1,331,834
to Chase for the net book value of the Portland, Oregon facility which is
expected to be sold.  The sale proceeds will be contributed to Chase to be
applied against the mortgage indebtedness currently encumbering such
facility.  The payable to Chase will not be paid until the facility has
been sold and the proceeds received by the Company.  The spin-off of Chase
by a dividend distribution resulted in a charge to paid-in capital of
approximately $29,000.

The expanded recording capabilities provided by the new system should
increase revenue and profit margins thereby improving the Company's
operating cash flow for the remainder of 1996.  Due to the potential for
downtime from contract delays and the uncertainty of weather, however, no
assurance can be given that the Company's liquidity will improve to levels
anticipated by management.

The Company maintains Club memberships for certain of its executive
officers.  Although these memberships may be utilized from time-to-time for
non-business purposes, the costs attributable to non-business purposes were
not material. The Company believes that the aggregate amounts of such
personal benefits do not exceed 10% of cash compensation paid to any
individual in the table or, with respect to the group of all executive
officers, ten percent(10%) of the aggregate cash compensation paid to the
members of such group.  

401(k) Plan

In 1987, the Company implemented a 401(k) salary deferral plan (the
Plan) which covers all employees who have reached the age of 20-1/2 years
and have been employed by the Company for at least one year.  The covered
employees may elect to have an amount deducted from their wages for
investment in a retirement plan.  The Company has the option, at its
discretion, to make contributions to the Plan.  Effective January 1, 1990,
the Company determined in its discretion to make a matching contribution to
the Plan equal to 10% of the employees' contributions up to 6% of those
employees' compensation.  On July 24, 1991, to be effective August 5, 1991,
the Board of Directors increased the Company's matching contribution to the
Plan to fifty cents ($.50) for every one dollar ($1.00) of compensation a
participant defers under the Plan up to 6% of those employees'
compensation.  Beginning January 4, 1993, the Board of Directors
discontinued the matching contribution to the Plan.  Concurrently with the
acquisition of Chase Packaging, the Board of Directors reinstated
contributions to the 401(k) salary deferral plan.  The Company makes a
matching contribution to the Plan equal to the sum of seventy-five percent
(75%) of each Participant's salary reduction contributions to the Plan for

                                                                  Page 38
such Plan year which are not in excess of three percent (3%) of the
Participant's compensation for such Plan year, and fifty percent (50%) of
each Participant's salary reduction contributions to the Plan for such Plan
Year which are in excess of three percent (3%) of the Participant's
compensation but not in excess of eight percent (8%) of the Participant's
compensation for such Plan Year. The total amount of the Company's
contribution during 1995 for the four (4) executive officers of the Company
participating in the 401(k) Plan was as follows:  Allen T. McInnes -
$3,483.85;  Robert J. Campbell -$3,923.50; Wayne A. Whitener -$2,877.40; 
and Doug Kirkpatrick - $2,548.58.


Stock Option Plans

1986 Incentive and Nonqualified Stock Option Plan

TGC's 1986 Incentive and Nonqualified Stock Option Plan is administered by
a Stock Option Committee consisting of three members of the Board of
Directors.  The Stock Option Committee recommends, and the Board grants,
options covering TGC's Common Stock to TGC's officers and/or employees
based upon the value or potential value of services rendered by such
persons. The exercise price for options granted under the Nonqualified Plan
will be determined by the Stock Option committee on the date of grant; the
exercise price for options granted under the Incentive Plan will not be
less than the market value of the Common Stock on the date of grant.  All
options must be exercised within five years from the date of grant.  No
options may be exercised during the first 12 months following grant. 
During the second year following the date of grant, options covering up to
one-third of the shares covered thereby may be exercised, and during the
third year options covering up to two-thirds of such shares may be
exercised.  Thereafter, and until the options expire, the optionee may
exercise options covering all of the shares.  Persons over sixty-five on
the date of grant may exercise options covering up to one-half of the
shares during the first year and thereafter may exercise all optioned
shares. Subject to the limitations just described, options may be exercised
as to all or any part of the shares covered thereby on one or more
occasions, but, as a general rule, options cannot be exercised as to

                                                                  Page 39
less than one-hundred shares at one time.  The right to exercise is
contingent upon continued employment with the Company; provided, however,
that if any optionee becomes permanently disabled, then such optionee may
exercise his option at any time within ninety (90) days after the
termination of such employment due to disability. Notwithstanding the
provisions discussed above, upon a Change of Control (as defined in the
Incentive and Nonqualified Stock Option Plan) all options outstanding at
such time will become immediately exercisable in full.  During 1995, no
options were granted under the Plan.  In May 1996, 25,000 stock options
were granted under the Plan.  Granted options covering a total of 51,668
shares are outstanding under the Plan.  The Plan terminated on July 24,
1996.  Any stock option outstanding at the termination date will remain
outstanding until it has been exercised, terminated, or has expired.

1993 Stock Option Plan

On June 3, 1993, the Company's Board of Directors approved and adopted the
Company's 1993 Stock Option Plan (the "1993 Stock Option Plan").  At the
1994 Annual Meeting, shareholders approved the 1993 Stock Option Plan.  The
following paragraphs summarize certain provisions of the 1993 Stock Option
Plan and are qualified in their entirety by reference thereto.      

The 1993 Stock Option Plan provides for the granting of options
(collectively, the "Options") to purchase shares of the Company's Common
Stock to certain key employees of the Company (and/or any of its
affiliates), and certain individuals who are not employees of the Company
but who from time-to-time provide substantial advice or other assistance or
services to the Company (and/or any of its affiliates).  The 1993 Stock
Option Plan authorizes the granting of options (both statutory and
non-statutory) to acquire up to 750,000 shares of Common Stock, subject to
certain adjustments described below, to be outstanding at any time. 
Subject to the foregoing, there is no limit on the absolute number of
awards that may be granted during the life of the 1993 Stock Option Plan. 
At the present time, there are approximately 66 employees of the Company,
including four officers of the Company (three of whom are also directors),
who, in management's opinion, would be considered eligible to receive
grants under the 1993 Stock Option Plan, although fewer employees may

                                                                  Page 40
actually receive grants.

Authority to administer the 1993 Stock Option Plan has been delegated to a
committee (the "Committee") of the Board of Directors.  Except as expressly
provided by the 1993 Stock Option Plan, the Committee has the authority, in
its discretion, to award Options and to determine the terms and conditions
(which need not be identical) of such Options, including the person to
whom, and the time or times at which, Options will be awarded, the number
of Options to be awarded to each such person, the exercise price of any
such Options, and the form, terms, and provisions of any agreement pursuant
to which such Options are awarded.  The 1993 Stock Option Plan also
provides that the Committee may be authorized by the Board of Directors to
make cash awards as specified by the Board of Directors to the holder of an
Option in connection with the exercise thereof.  

Subject to the limitations set forth below, the exercise price of the
shares of stock covered by each 1993 Option will be determined by the
Committee on the date of award.

Unless a holder's option agreement provides otherwise, the following
provisions will apply to exercise by the holder of his or her option:  No
options may be exercised during the first twelve months following grant. 
During the second year following the date of grant, options covering up to
one-third of the shares covered thereby may be exercised, and during the
third year following the date of grant, options covering up to two-thirds
of such shares may be exercised.  Thereafter, and until the options expire,
the optionee may exercise options covering all of the shares.  With regard
to approximately one-half of the options which have been granted, the
Grantee can exercise up to one-half of the number of shares covered by an
option during the first twelve months following the date of grant, and the
balance thereafter (with the latter being limited in some cases to
individual performance). Persons over sixty-five on the date of grant may
exercise options covering up to one-half of the shares during the first
year and thereafter may exercise all optioned shares. Subject to the
limitations just described, options may be exercised as to all or any part
of the shares covered thereby on one or more occasions, but, as a general
rule, options cannot be exercised as to less than one-hundred shares at any

                                                                  Page 41
one time.

The exercise price of the shares of stock covered by each incentive stock
option ("ISO"), within the meaning of Sec. 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), will not be less than the fair market
value of stock on the date of award of such ISO except that an ISO may not
be awarded to any person who owns stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the
Company unless the exercise price is at least one hundred ten percent
(110%) of the fair market value of the stock at the time the ISO is awarded
and the ISO is not exercisable after the expiration of five years from the
date it is awarded. The exercise price of the shares of Common Stock
covered by each Option that is not an ISO will not be less than fifty
percent (50%) of the fair market value of the stock on the date of award.  

Payment for Common Stock issued upon the exercise of an Option may be made
in cash or with the consent of the Committee, in whole shares of Common
Stock owned by the holder of the Option for at least six months prior to
the date of exercise or, with the consent of the Committee, partly in cash
and partly in such shares of Common Stock.  If payment is made, in whole or
in part, with previously-owned shares of Common Stock, the Committee may
issue to such holder a new Option for a number of shares equal to the
number of shares delivered by such holder to pay the exercise price of the
previous Option having an exercise price equal to at least one-hundred
percent (100%) of the fair market value per share of the Common Stock on
the date of the exercise of the previous Option.  

The duration of each Option will be for such period as the Committee
determines at the time of award, but not for more than ten years from the
date of award in the case of an ISO. 

In the event of any change in the number of shares of Common Stock effected
without receipt of consideration therefor by the Company by reason of a
stock dividend, or split, combination, exchange of shares or other
recapitalization, merger, or otherwise, in which the Company is the
surviving Corporation, the aggregate number and class of reserved shares,
the number and class of shares subject to each outstanding Option, and the 

                                                                   Page 42
exercise price of each outstanding Option will be automatically adjusted to
reflect the effect thereon of such change.  Unless a holder's option
agreement provides otherwise, a dissolution or liquidation of the Company,
certain sales of all or substantially all of the assets of the Company,
certain mergers or consolidations in which the Company is not the surviving
corporation, or certain transactions in which another corporation becomes
the owner of fifty percent (50%) or more of the total combined voting power
of all classes of stock of the Company, will cause such holder's Options
then outstanding to terminate, but such holder may, immediately prior to
such transaction, exercise such options without regard to the period and
installments of exerciseability applicable pursuant to such holder's option
agreement.

The 1993 Stock Option Plan will terminate on June 3, 2003, or such earlier
date as the Board of Directors may determine.  Any stock option outstanding
at the termination date will remain outstanding until it has been
exercised, terminated, or has expired. The 1993 Stock Option Plan may be
terminated, modified, or amended by the Board of Directors at any time
without further shareholder approval, except that shareholder approval is
required for any amendment which:  (a) changes the number of shares of
Common Stock subject to the 1993 Stock Option Plan other than by adjustment
provisions provided therein,  (b) changes the designation of the class of
employees eligible to receive Options,  (c) decreases the price at which
ISO's may be granted, (d) removes the administration of the 1993 Stock
Option Plan from the Committee, or (e) without the consent of the affected
holder, causes the ISO's granted under the 1993 Stock Option Plan and
outstanding at such time that satisfied the requirements of Sec. 422 of the
Code no longer to satisfy such requirements.

During 1995 no stock options were granted under the Company's 1993 Stock
Option Plan to officers and employees of the Company.  A total of 590,000
stock options were granted in January, April, and June, 1996.  Granted
options covering a total of 625,000 shares are outstanding under the 1993
Stock Option Plan.

On January 9, 1995, options for 4,000 shares and 2,332 shares of Common
Stock at an exercise price of $.875 and $1.00, respectively, per share were
exercised by Mr. Wayne Whitener, President of the Company. The Company
received 1,458 shares of its Common Stock at a market value of $4.00 per
share as payment for the exercise of the options.

On February 1, 1995, Mr. Allen T. McInnes, Chairman and CEO of the Company,
exercised stock options to purchase 125,000 shares of Common Stock.  The
Company received $100,000 representing payment in full of the exercise
price of the option.

                        TRANSACTIONS WITH MANAGEMENT

On May 31, 1994 the holder of the 9% Convertible Subordinated Preferred
Stock elected to convert the Preferred Stock into 26,666 shares of TGC
Common Stock.  On July 2, 1994, 500,000 shares of Convertible Preferred
Stock held by certain affiliates of the Company were converted into
1,530,000 shares of the Company's Common Stock.  Pursuant to the terms
governing the Preferred Stock and based upon the Company having achieved a
trading price for its Common Stock of $1.60 per share for thirty
consecutive trading days, all holders of the Convertible Preferred Stock
elected to exercise their conversion privilege as of this date.

On July 28, 1995, 64,676 shares of Common Stock were contributed to the
Company by a Director of TGC Industries, Inc.  The Company included these
shares in its treasury stock account at $2.50 per share which represents
the fair market value of the Company's Common Stock on the date of the
transaction.

On July 31, 1995, certain executive officers and directors of the Company
exchanged $200,000 in short-term debt for Private Placement Units.  On
August 1, 1995,  4,874 Units were issued as payment of accrued interest on
this debt.

In the fourth quarter of 1995, certain executive officers and directors of
the Company made loans to the Company in the amount of $240,000 due to the
cash requirements of the Company at the time. Interest expense of $3,538.35
was accrued on these loans for this period. 

Certain directors and officers of the Company exchanged $365,812 of debt
for Series C 8% Convertible Exchangeable Preferred Stock in connection with

                                                                  Page 45
the private placement of such Preferred Stock in July, 1996.

                          DESCRIPTION OF SECURITIES

The Company's Articles of Incorporation authorize 25,000,000 shares of
Common Stock with a par value of $.10 per share.  Each holder of Common
Stock is entitled to one vote per share held of record at each meeting of
the stockholders.  As of July 31, 1996, there were 6,188,018 shares of the
Company's Common Stock outstanding.  The Company is also authorized to
issue 4,000,000 shares of Preferred Stock with a par value of $1.00 per
share. The Board of Directors authorized the issuance of 1,250,000 shares
of Series C 8% Convertible Exchangeable Preferred Stock.  Each holder of
Preferred Stock is entitled to one vote per share held of record at each
meeting of the stockholders.  As of July 31, 1996, there were 1,150,350
shares of the Company's Preferred Stock outstanding.  The Preferred Stock
is convertible into shares of the Company's Common Stock and is convertible
at the conversion price per share in years one and two at $.75, year three
at $1.25, and thereafter at $2.00.  Dividends at the rate of 8% per annum
will accrue from the closing date and are payable, upon declaration by the
Board of Directors, semi-annually, commencing January 1, 1997.  The
Preferred Stock is exchangeable in whole by the Company, at its sole
option, into 8% Subordinated Convertible Debentures, Series A; provided
that the Company may not exercise such exchange option prior to January 1,
1998.

Warrants

The Company issued Warrants as a component of Units offered in a private
placement that closed in September, 1995.  As of July 31, 1996, there were
737,174 Warrants issued in connection with that private placement
outstanding.  Each Warrant is exercisable for the purchase of one share of
Common Stock for a period of 3 years from September 8, 1995 at $.375 per
share.  The Warrants are not callable or redeemable by the Company prior to
the end of the 3 year term.  If not exercised at the end of the 3 year
term, each Warrant certificate or certificates representing, immediately
before the end of their term, the right to purchase one share of Common
Stock will automatically convert into one-tenth of one share of Common 

                                                                  Page 46
Stock of the Company.  Fractional shares will not be issued upon the 
exercise of the Warrants.  In lieu thereof, a cash adjustment based on the
fair market value of the Common Stock on the date of exercise will be made.

 The Company entered into a Warrant agreement with American Stock Transfer
and Trust Company, as the Warrant agent in favor of the Warrant holders,
which provides that the number of shares of Common Stock to be obtained
upon exercise of a warrant, and the exercise price, are subject to
adjustment (a) in the event of a stock dividend, split-up, sub-division,
combination, or reclassification of the Company's Common Stock, and (b) for
any capital reorganization or reclassification of the Common Stock of the
Company, any mergers or consolidations of the Company with another entity,
or the sale of substantially all of the assets of the Company.

Series C 8% Convertible Exchangeable Preferred Stock

The following summaries of certain provisions of the Series C 8%
Convertible Exchangeable Preferred Stock do not purport to be complete and
are subject to, and are qualified in their entirety by reference to all
provisions of the Statement of Resolution Establishing Series C 8%
Convertible Exchangeable Preferred Stock attached as Exhibit "A" hereto,
including the definitions therein of certain terms.

General

The Company is authorized to issue shares of preferred stock in series, and
in connection with such issuance, the Board of Directors of the Company is
authorized without a further vote of the shareholders to fix the rights and
qualifications, limitations or restrictions of any series of preferred
stock, including the number of shares constituting any such series and the
designation thereof, the voting rights, rights and terms of redemption,
dividend rights, liquidation preferences and the rights and terms of
conversion into shares of any other class or classes or any other series of
the same or any other class or classes of stock of the Company.  The Board
of Directors has resolved that 1,250,000 shares of the Company's
undesignated shares be designated as Series C 8% Convertible Exchangeable
Preferred Stock (the "Preferred Stock").  Prior to the offering of the 

                                                                  Page 47

designation of the Series C Preferred Stock, no series of preferred stock
was outstanding.  To the extent that all shares of the Preferred Stock are
not issued, the Board of Directors of the Company would have the authority,
without shareholder approval, to issue the remaining undesignated shares
 with voting, conversion, liquidation, dividend and other rights which
could be on a parity with the Preferred Stock.  In addition, future
issuances of additional shares of preferred stock could make it more
difficult for a third party to acquire a majority of the outstanding voting
stock of the Company and accordingly may be used as an anti-takeover
device.

The Company issued 1,150,350 shares of Series C 8% Convertible Exchangeable
Preferred Stock in connection with a private placement that closed in July,
1996.  The following is a description of the Preferred Stock which does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the Company's Articles of Incorporation, and the Statement of
Resolution Establishing Series C 8% Convertible Exchangeable Preferred
Stock (the "Statement of Resolution") filed with the Secretary of State of
Texas, which is attached as Exhibit "A" hereto.

Dividends

Holders of shares of the Preferred Stock will receive, when, as and if
declared by the Board of Directors of the Company, dividends at a rate of
eight percent (8%) per annum, payable semi-annually on January 1 and July 1
of each year, commencing January 1, 1997.  Dividends will be cumulative,
will accumulate from the date of original issuance and will be payable to
holders of record of the Preferred Stock as they appear on the books of the
Company on such respective dates, not exceeding 60 days preceding such
dividend payment date, as may be fixed by the Board of Directors of the
Company in advance of the payment of each particular dividend.

The Preferred Stock ranks senior to the Common Stock as to dividends and
upon liquidation.  Before any dividends (other than dividends payable in
Common Stock) on any class or series of stock of the Company ranking junior
to the Preferred Stock as to dividends or upon liquidation shall be
declared or paid or set apart for payment, the holders of shares of the 

                                                                  Page 48
Preferred Stock are entitled to receive cumulative cash dividends, but only
when and as declared by the Board of Directors, at the rate set forth
above.  No dividends can be declared on any class or series of stock
ranking on a parity with the Preferred Stock as to dividends in respect of
any dividend period unless there shall likewise be or have been declared on
the Preferred Stock like dividends for all semi-annual periods coinciding
with or ending before such semi-annual period ratably in proportion to the
respective annual dividend rates fixed therefor.  If the Company is in
default with respect to any dividends payable on its Preferred Stock, the
Company may not declare or pay or set apart for payment any dividends or
make any distribution in cash or other property on, or redeem, purchase or
otherwise acquire, any other class or series of stock ranking junior to the
Preferred Stock either as to dividends or upon liquidation.  Accruals of
dividends will not bear interest.
 
The amount of dividends payable per share for each dividend period shall be
computed by dividing the annual rate by two (2).  The amount of dividends
payable for the initial dividend period or any period shorter than a full
dividend period shall be computed on the basis of a 360-day year of 12
30-day months.

Conversion

The holders of Preferred Stock are entitled at any time to convert their
shares of Preferred Stock into shares of Common Stock at the following
conversion rates (subject to adjustment as described below):

(a)  prior to the close of business on July 1, 1998, at the conversion
     price per share of Common Stock of Seventy-Five Cents ($0.75);

(b)  after July 1, 1998, and prior to the close of business on July 1,
     1999, at the conversion price per share of Common Stock of One Dollar
     and Twenty-Five Cents ($1.25); and 

(c)  thereafter, at the conversion price per share of Common Stock of Two
     Dollars ($2.00).


                                                                  Page 49

Shares of Preferred Stock surrendered for conversion during the period from
the close of business on any record date for the payment of dividends on
such Preferred Stock to the opening of business on the corresponding
dividend payment date (except shares called for redemption during such
period) must be accompanied by payment of an amount equal to the dividend
payable on such shares on the corresponding dividend payment date
notwithstanding the conversion thereof or the Company's default in payment
of the dividend due on such dividend payment date.  A holder of Preferred
Stock on a dividend payment date will receive the dividend payable on such
Preferred Stock by the Company on such date, and the converting holder need
not include payment in the amount of such dividend upon surrender of shares
of Preferred Stock for conversion.

No fractional shares will be issued upon conversion and, in lieu thereof,
an adjustment in cash will be made based upon the last reported sale price
of the Common Stock (or if not available, the average of the closing bid
and asked prices) on the NASDAQ National Market System or SmallCap Market,
on the principal national securities exchange, or the over-the-counter
system where the Common Stock may then be traded, on the last business day
prior to the date of such conversion.

The conversion rate is subject to adjustment in certain events, including
(i) the issuance of capital stock of the Company as a dividend or a
distribution, (ii) subdivisions, combinations and reclassifications of the
Common Stock, and (iii) the distribution to all holders of Common Stock of
evidences of indebtedness of the Company or of assets (other than cash
dividends from retained earnings) or subscription rights to securities of
the Company.  Except in these cases, the conversion rate will not be
adjusted for the issuance of Common Stock.  The Company reserves the right
to make such increases in the conversion rate in addition to those required
by the foregoing provisions as the Company in its discretion shall
determine to be advisable in order that certain stock related distributions
hereafter made by the Company to its shareholders shall not be taxable.

Except as discussed above, no adjustment upon conversion will be made for
dividends on either the Preferred Stock or the Common Stock.


                                                                  Page 50
In case of any consolidation or merger of the Company with or into another
corporation or entity other than a consolidation or merger in which the
Company is the continuing corporation and which does not result in any
reclassification of or change in outstanding shares of Common Stock, or any
sale or transfer of all or substantially all the assets of the Company, the
holder of each share of Preferred Stock shall after such consolidation,
merger, sale or transfer have the right to convert such share of Preferred
Stock into the kind and amount of securities, cash and other property which
such holder would have been entitled to receive upon such consolidation,
merger, sale or transfer if the holder had held the Common Stock issuable
upon the conversion of such share of Preferred Stock immediately prior to
such consolidation, merger, sale or transfer.

Redemption at Option of the Company

Except for any redemption which the Company would be prohibited from
effecting under applicable law, and provided the shares of Preferred Stock
of a holder have not earlier been converted or exchanged in accordance with
the provisions of the Preferred Stock, the shares of Preferred Stock may be
redeemed by the Company, in whole or in part, at the option of the Company
upon written notice by the Company to the holders of Preferred Stock at any
time after July 1, 2000, in the event that the Preferred Stock of one or
more holders has not been converted or exchanged pursuant to the terms
hereof on or before such date.  The Company shall redeem each share of
Preferred Stock of such holders within thirty (30) days of the Company's
delivery of the above notice to such holders and such holders shall
surrender the certificate(s) representing such shares of Preferred Stock. 
For any partial redemptions the Company shall redeem shares in proportion
to the number of shares held by each holder.  The redemption amount shall
be $5.00 per share, plus in each case accrued and unpaid dividends thereon
to the date of payment of such amount (the total sum so payable on any such
redemption being herein referred to as the "redemption price"); provided,
however, that for any such redemption which is effected (i) on or after
July 1, 2001 but prior to July 1, 2002, a premium of ten percent (10%) of
the per share amount of such Preferred Stock shall be paid per share (i.e.
$0.50 per share of Preferred Stock), (ii) on or after July 1, 2002 but
prior to July 1, 2003, a premium of 20% per share (i.e. $1.00 per share);

                                                                  Page 51
(iii) on or after July 1, 2003 but prior to July 1, 2004, a premium of 30%
per share (i.e. $1.50 per share); (iv) on or after July 1, 2004 but prior
to July 1, 2005, a premium of 40% per share (i.e. $2.00 per share); and on
or after July 1, 2005 a premium of 50% per share (i.e. $2.50 per share).

Upon payment of such redemption price, the shares represented thereby shall
no longer be deemed outstanding, the right to receive dividends and
distributions shall cease to accrue on and after such date, and all rights
of the holder of the Preferred Stock as a shareholder of the Company shall
cease and terminate.

Exchange into Subordinated Convertible Debentures

The Preferred Stock is exchangeable in whole, but not in part, at the sole
option of the Company into the Company's 8% Subordinated Convertible
Debentures, Series A at an exchange rate of $5.00 principal amount of
Subordinated Debentures for each share of Preferred Stock; provided that
the Company may not exchange any shares of Preferred Stock unless all
cumulative dividends have been paid to the date of exchange.  The Company's
exchange option is further restricted by the terms of the Preferred Stock
which provide the Company may not exercise such exchange option prior to
January 1, 1998.  Furthermore, under the terms of the Preferred Stock:  (1)
the maturity date of the Convertible Debentures will be equal to the later
of July 1, 2000 or two years from the date of exchange of such Preferred
Stock, and (2) in the event of an exchange of Preferred Stock for
Convertible Debentures on or after July 1, 2001, the principal amount of
Debentures exchanged for each share of Preferred Stock shall include a
premium identical to the premium described above with respect to the
Company's exercise of its redemption option or after such date (e.g. for an
exchange on or after July 1, 2001 but prior to July 1, 2002, a premium of
ten percent (10%) of the principal amount of the Debentures per share (i.e.
a premium of $0.50 per share of Preferred Stock or a Convertible Debenture
in the principal amount of $5.50 per share of Preferred Stock.))

Under the terms of the Convertible Debentures, the Debentures will have a
maturity date equal to the later of July 1, 2000 or two years from the date
of exchange.  The Company shall send to each holder of Preferred Stock

                                                                  Page 52
notice of the exchange not less than 30 days nor more than 60 days prior to
the exchange date at the address shown on the books of the Company.  On and
after the date of exchange of Preferred Stock for Subordinated Debentures,
the Preferred Stock shall cease to accrue dividends, shall no longer be
deemed to be outstanding and shall represent only the right to receive the
Subordinated Debentures.

Voting Rights

The holders of the shares of Preferred Stock are entitled to one vote per
share of Preferred Stock held by them, to vote upon all matters which the
holders of shares of the Company's Common Stock shall have the right to
vote.  In all cases, as a matter of law, where the holders of shares of
Preferred Stock shall have the right to vote separately as a class, such
holders will also be entitled to one vote per share of Preferred Stock held
by them.

The affirmative vote or consent of the holders of at least two-thirds of
the outstanding shares of the Preferred Stock, voting as a class, will be
required to (i) authorize, create or issue, or increase the authorized or
issued amount of, shares of any class or series of stock ranking senior to
the Preferred Stock, either as to dividends or upon liquidation, or (ii)
amend, alter or repeal (whether by merger, consolidation or otherwise) any
provisions of the Company's Articles of Incorporation or of the Statement
of Resolution establishing this series of Preferred Stock so as to
materially and adversely affect the preferences, special rights or powers
of the Preferred Stock; provided, however, that any increase in the
authorized preferred stock or the creation and issuance of any other series
of preferred stock ranking on a parity with or junior to the Preferred
Stock shall not be deemed to materially and adversely affect such
preferences, special rights or powers.

Liquidation Rights

In the event of any liquidation, dissolution or winding-up of the Company,
whether voluntary or involuntary, before any payment or distribution of the
assets of the Company, or proceeds thereof (whether capital or surplus),

                                                                  Page 53
shall be made to or set apart for the holders of any class of stock of the
Company ranking junior to the Preferred Stock upon liquidation, the holders
of the Preferred Stock shall be entitled to receive $5.00 per share, plus
an amount equal to all dividends (whether or not earned or declared)
accrued and unpaid to the date of final distribution, but such holders
shall not be entitled to any further payment.  If, upon any liquidation,
dissolution or winding-up of the Company, the assets of the Company, or
proceeds thereof, distributable among the holders of shares of the
Preferred Stock and any other class or series of preferred stock ranking on
a parity with the Preferred Stock as to payments upon liquidation,
dissolution or winding-up shall be insufficient to pay in full the
preferential amount aforesaid, then such assets, or the proceeds thereof,
shall be distributed among such holders ratably in accordance with the
respective amounts that would be payable on such shares if all amounts
payable thereon were paid in full.  The voluntary sale, conveyance, lease,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Company to, or a consolidation or merger of the Company with, one or more
other corporations (whether or not the Company is the corporation surviving
such consolidation or merger) will not be deemed to be a liquidation,
dissolution or winding-up, voluntary or involuntary.

8% Subordinated Convertible Debentures, Series A

If the Company elects to exchange the Preferred Stock for the Company's 8%
Subordinated Convertible Debentures, Series A ("Subordinated
Debentures"),the Company will issue the Subordinated Debentures to all
holders of Preferred Stock.  The following summaries of certain provisions
of the Subordinated Debentures, do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all
provisions of the Form of Debenture Agreement and the Debenture attached as
Exhibit "B" hereto, including the definitions therein of certain terms.

General

The Subordinated Debentures will be unsecured, subordinated obligations of
the Company, limited to an aggregate principal amount equal to the

                                                                  Page 54
aggregate stated value of the Preferred Stock for which the Subordinated
Debentures are exchanged, and will mature on the later of July 1, 2000 or
two years from the date of exchange of Preferred Stock for Subordinated
Debentures.  The Company will pay interest on the Subordinated Debentures
semi-annually at 8% per annum, the same rate as paid on the Preferred
Stock.  Interest will be paid on the Subordinated Debentures to the persons
who are registered holders at the close of business on the 15th day of the
month next preceding the interest payment date.  Interest will be computed
on the basis of a 360-day year of 12 30-day months.  Principal and interest
will be payable and the Subordinated Debentures may be presented for
conversion, exchange or transfer at the principal office of the Company.

Conversion Rights

The holders of Subordinated Debentures will be entitled at any time on or
before the maturity thereof to convert the Subordinated Debentures into
Common Stock of the Company.  The initial conversion price of the
Debentures will be at the same conversion price in effect for the Preferred
Stock at the date of exchange of the Preferred Stock for Subordinated
Debentures.  Following the date of exchange, the terms of the Debentures
with respect to the conversion price and the adjustments to the conversion
price are identical, in all material respects, to such terms contained in
the Preferred Stock as described above.

Subordination

The payment of principal (and premium, if any) and interest on, the
Subordinated Debentures is subordinated in right of payment to the payment
of all Superior Indebtedness of the Company.  "Superior Indebtedness" is
defined as (a) Funded Debt, being all indebtedness of the Company having a
final maturity of more than one year, and all guarantees of indebtedness
extending more than one year, from its "date of origin" or which is
renewable or extendable at the option of the obligor for a period or
periods of more than one year from its date of origin, and all amounts due
under capitalized leases reflected on the balance sheets; and (b) Current
Debt, being all unsecured indebtedness for money borrowed, payable on
demand or having a maturity or not more than one year from the date of

                                                                  Page 55
determination (other than current maturities of Funded Debt) and not
extendable or renewable at the option of obligor.

The Company is not limited in the amount of Superior Indebtedness that may
be incurred and the Company may from time to time incur additional Superior
Indebtedness.  In addition, any subsidiary of the Company may incur
liabilities and have obligations to third parties.  The claims of such
third parties to the assets of such subsidiaries will be superior to those
of the Company as a shareholder and therefore the Subordinated Debentures
may be deemed to be effectively subordinated to the claims of such third
parties.

In the event of any payment or distribution of assets or securities of the
Company upon any liquidation, dissolution, winding-up or reorganization of
or similar proceeding relating to the Company, the payment of the principal
(and premium, if any) and interest on the Subordinated Debentures is to be
subordinated in right of payment to the prior payment in full of all
Superior Indebtedness.  No payment on account of principal (and premium, if
any) or interest on the Subordinated Debentures may be made if, at the time
of such payment, or immediately after giving effect thereto, there exists a
default with respect to any Superior Indebtedness provided that no such
event of default will prevent payment on the Subordinated Debentures for
more than 180 days unless the holder of such Superior Indebtedness has
commenced judicial proceedings with respect to such default within such
period.  Upon payment or distribution of assets or securities of the
Company upon any liquidation, dissolution, winding-up or reorganization of
or similar proceedings relating to the Company, the holders of Superior
Indebtedness will be entitled to receive payment in full before the holders
of Subordinated Debentures are entitled to receive any payment.

By reason of such subordination, in the event of insolvency, creditors of
the Company who are holders of Superior Indebtedness may recover more,
ratably, than the holders of the Subordinated Debentures.

Prepayment of Debentures

The Company may, at any time after March 31, 1997, prepay the Notes in

                                                                  Page 56
whole or in part (in amounts of not less than $50,000) by payment of one
hundred ten percent (110%) of the principal amount of the Notes, or portion
thereof to be prepaid, and payment of the accrued interest thereon to the
date of prepayment.  The Company shall give written notice of any such
prepayment of the Debentures to each holder thereof not less than thirty
(30) days nor more than sixty (60) days before the date fixed for such
optional prepayment.  Such notice shall specify (i) such date, and (ii) the
principal amount of the holder's Debentures to be prepaid and the aggregate
principal amount of all Debentures to be prepaid. 

Upon the occurrence of either of the following events, and upon the written
request of any holder of the Debentures, the Company shall prepay such
holder's Debentures in whole by payment of one hundred percent (100%) of
the principal amount of the Debentures and payment of the accrued interest
thereon to the date of prepayment, within thirty (30) days of the Company's
receipt of such written request: (a) in the event that a person, who as of
May 15, 1996 owned no more than five percent (5%) of the issued and
outstanding shares of Common Stock of the Company (no preferred stocks
being issued and outstanding at such date), shall acquire ownership of that
portion of the issued and outstanding Common Stock and/or preferred stock
of the Company which in the aggregate possesses thirty-five percent (35%)
or more of the voting rights of all issued and outstanding shares of Common
Stock and preferred stock of the Company, or (b) in the event of the
consolidation with or merger of the Company with or into another
corporation or entity, or in the event of the sale, lease or conveyance to
another corporation or entity of the assets of the Company as an entirety
or substantially as an entirety.

Defaults and Remedies

An Event of Default under the Debenture Agreement is defined as: default
for 15 days in payment of interest on the Subordinated Debentures; default
in payment of principal of the Subordinated Debentures at maturity; failure
by the Company for 30 days after notice to it to comply with any of its
other covenants in the Debenture Agreement; the sale by the Company of all
or substantially all of its assets; and certain events of bankruptcy,
insolvency or reorganization.  If an Event of Default occurs and is

                                                                  Page 57
continuing, the holder of a Subordinated Debenture may, upon 10 days prior
written notice, declare his Subordinated Debenture to be due and payable
immediately, provided that the holders of 51% of the aggregate principal
amount of the Debentures may waive any such Event of Default.

Modification and Amendment

Modification and amendment of the Debenture Agreement may be effected by
the Company with the consent of the holders of 66 2/3% of the aggregate
principal amount of the Subordinated Debentures, provided that no such
modification or amendment may, without the consent of each holder affected
thereby: reduce the amount of Subordinated Debentures whose holders must
consent to an amendment; reduce the rate or change the time and place for
payment of interest on any Subordinated Debenture; reduce the principal of
or change the fixed maturity of any Subordinated Debenture; or make any
Debenture convertible into any securities other than as described in the
Debenture Agreement.

Common Stock

The Company's Articles of Incorporation authorize 25,000,000 shares of
Common Stock with a par value of $.10 per share.  Each holder of Common
Stock is entitled to one vote per share held of record at each meeting of
the stockholders.  As of July 31, 1996, there were 6,188,018 shares of the
Company's Common Stock outstanding.  Subject to the rights of the holders
of shares of Preferred Stock which are issued and outstanding from time to
time, holders of Common Stock are entitled to such dividends as may be
declared from time to time by the Board of Directors of the Company out of
funds legally available therefor and to participate pro-rata in dividends
and, upon liquidation, any distribution to stockholders.  The Common Stock
carries no preemptive, subscription, or cumulative voting rights or
redemption or sinking fund provisions.

The Articles of Incorporation and Bylaws of the Company provide
authorization for dividing the Board of Directors into three separate
classes having staggered terms so that only one-third of the total number
of directors is up for election at each annual meeting of the shareholders

                                                                  Page 58
of the Company.  The Articles of Incorporation also provide that the
provision authorizing such a classification of the Board of Directors may
not be amended, altered, changed or repealed in any respect without an
affirmative vote of the holders of not less than eighty percent (80%) of
the then outstanding shares of capital stock of the Company at a meeting
called for such purpose.  At the present time, the Company does not
anticipate that a division of the Board of Directors into three separate
classes with each class having a staggered term, as provided above, will be
placed into effect.

Executive Compensation."

                            PLAN OF DISTRIBUTION

Certain Selling Security Holders are offering for sale pursuant to this
Prospectus a total of 1,150,350 shares of Preferred Stock and a total of
737,174 Warrants of the Company.  Additionally, Certain Selling Security
Holders are offering for sale pursuant to this Prospectus a total of
900,506 shares of Common Stock of the Company.  The Warrants and shares of
Preferred Stock and Common Stock offered for sale hereby are presently held
by the Selling Security Holders.  Such Warrants and shares of Preferred
Stock and Common Stock will be offered for sale to the public (if at all)
only in such amounts as determined in each such holder's sole discretion.

It is anticipated that the Warrants and the shares of Preferred Stock and
Common Stock will be offered in the NASDAQ SmallCap Market (or, if not
available for the Warrants or the Preferred Stock, the over-the-counter
market)  or in negotiated transactions or block trades, at fixed prices
which may be changed, at market prices prevailing at the time of sale, at
prices related to such prevailing market prices, or at negotiated prices.
The Warrants and the shares of Preferred Stock and Common Stock offered
hereby may be sold from time to time on a best efforts basis through
registered broker-dealers, to be selected by the Selling Security Holders,
who may receive compensation in the form of discounts, concessions, or
commissions from the Selling Security Holders and/or the purchaser of
shares for whom such broker-dealer may act as agent or to whom they sell as
principal, or both (which compensation to a particular broker-dealer may be
in excess of customary commissions).  It is anticipated that the offering
will continue until all of the securities offered hereby are sold or until
the Company determines, in its sole discretion, that such offering should
cease.  

There is no underwriter or coordinating broker acting in connection with
this offering.  In effecting sales, brokers or dealers engaged by the
Selling Security Holders may arrange for other brokers or dealers to
participate.  Brokers or dealers will receive commissions or discounts from
Selling Security Holders in amounts negotiated immediately prior to the
sale.  Such brokers or dealers and any other participating brokers or
dealers may be deemed to be "underwriters" within the meaning of the

                                                                  Page 69
Securities Act of 1933 (the "Securities Act") in connection with such
sales.  In addition, each Selling Security Holder may be deemed to be an
"underwriter" within the meaning of the Securities Act with respect to the
securities offered by him.  Any securities covered by this Prospectus which
qualify for sale pursuant to Rule 144 promulgated under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus.

In order to comply with certain states' securities laws, if applicable, the
Warrants and shares of Preferred Stock and Common Stock will be sold in
such jurisdictions only through registered or licensed brokers or dealers. 
In addition, in certain states the Warrants and shares of Preferred Stock
and Common Stock may not be sold unless the Warrants, Preferred Stock, and
Common Stock have been registered or qualified for sale in such state or an
exemption from registration or qualification is available and is complied
with.


           LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

As permitted by the provisions of the Texas Business Corporation Act, the
Articles of Incorporation of the Company eliminates in certain
circumstances the monetary liability of directors of the Company for a
breach of their fiduciary duty as directors.  These provisions do not
eliminate the liability of a director (i) for a breach of the director's
duty of loyalty to the corporation; (ii) for acts or omissions by a
director not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) for any transaction from which the director
derives an improper benefit whether or not the benefit resulted from an
action taken within the scope of the director's office; (iv) for an act or
omission for which the liability of a director is expressly provided by
statute; or (v) for an act related to an unlawful corporate distribution. 
In addition, these provisions do not limit the rights of the Company or its
stockholders, in appropriate circumstances, to seek equitable remedies such
as injunctive or other forms of non-monetary relief.  Such remedies may not
be effective in all cases.

The Company's Articles of Incorporation and Bylaws provide that the Company

                                                                  Page 70
shall indemnify all directors and officers of the Company to the full
extent permitted by the Texas Business Corporation Act.  Under such
provisions any director or officer who, in his capacity as such, is made or
threatened to be made a party to any suit or proceeding, shall be
indemnified if such director or officer acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of
the corporation.  The Articles of Incorporation, Bylaws, and the Texas
Business Corporation Act further provide that such indemnification is not
exclusive of any other rights to which such individuals may be entitled
under the Articles of Incorporation and the Bylaws or any other agreement,
vote of stockholders or disinterested directors, or otherwise.


                              LEGAL PROCEEDINGS

The Company is a defendant in various legal actions that arose out of the
normal course of business.  It is management's opinion, based on evaluation
and discussion with counsel, that the ultimate outcome of those matters
will not have a material adverse effect on the Company's financial position
or its results of operations.


                    INTEREST OF NAMED EXPERTS AND COUNSEL

Mr. Rice M. Tilley, Jr. is a shareholder in the law firm of Law, Snakard &
Gambill, P.C. and is an Assistant Secretary of the Company.

            Report of Independent Certified Public Accountants


Board of Directors and Stockholders
TGC Industries, Inc.


We have audited the accompanying consolidated balance sheet of TGC
Industries, Inc. and Subsidiary as of December 31, 1995, and the related
consolidated statements of operations, stockholders' equity and cash flows
for each of the two years in the period ended December 31, 1995.  These
financial statements are the responsibility of the Company's management. 
Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.


                                                                  Page 72
In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of TGC
Industries, Inc. and Subsidiary as of December 31, 1995, and the
consolidated results of their operations and their consolidated cash flows
for each of the two years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

                   TGC INDUSTRIES, INC. AND SUBSIDIARY
                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

               (Information pertaining to the periods ended 
                   June 30, 1995 and 1996 is unaudited)

NOTE A -  NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING 
          POLICIES

          A summary of the significant accounting policies consistently
          applied in the preparation of the accompanying consolidated
          financial statements follows:

          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.  The operations of its
          wholly-owned subsidiary, Chase Packaging Corporation (Chase),
          which manufactures woven paper mesh and polypropylene mesh fabric
          bags for agricultural and industrial use, are reflected as
          discontinued in the accompanying consolidated financial
          statements.  (See Note B).

          Principles of Consolidation

          The consolidated financial statements include the accounts of the
          Company and its wholly-owned subsidiary.  All significant
          intercompany accounts have been eliminated in consolidation.

          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 is
          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.

          Advance Billings

          Certain charges related to specific geophysical projects are
          billed in advance.  Also, certain customers of Chase pay in
          advance.  The related revenue is included in advance billings and
          recognized as income when earned.

          Interim Statements

          In the opinion of management, the unaudited interim financial
          statements as of June 30, 1996 and for the six-month periods
          ended June 30, 1995 and 1996 include all adjustments, consisting
          only of those of a normal recurring nature, necessary to present
          fairly the Company's financial position as of June 30, 1996 and
          the results of its operations and cash flows for the six-month
          periods ended June 30, 1995 and 1996.  The results of operations
          for the six months ended June 30, 1996 are not necessarily
          indicative of the results to be expected for the full year.

NOTE A - NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING 
         POLICIES - Continued

         Stock Options

         Statement of Financial Accounting Standards No. 123 (SFAS 123),
         "Accounting for Stock-Based Compensation" is effective for 1996. 
         SFAS 123 defines a fair value based method of accounting for an
         employee stock option to determine compensation cost at date of
         grant.  However, SFAS 123 allows a company to continue measuring
         compensation cost for those plans using the intrinsic value based
         method of accounting prescribed by APB Opinion No. 25 (APB 25),
         "Accounting for Stock Issued to Employees."  The Company elected
         to continue measuring compensation cost for stock options based on
         APB 25 and will provide the required pro forma disclosures
         prescribed in SFAS 123.

         Earnings (Loss) Per Share

         Earnings (loss) per common share is based upon the weighted
         average number of shares of common stock outstanding.  When
         dilutive, stock options are included as common stock equivalents
         using the treasury stock method.

         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 B - REORGANIZATION PLAN

         In May 1996, a formal plan was adopted to reorganize TGC and
         Chase.  Pursuant to the plan, the following actions have been
         taken:

         (a)  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 is, at the
              option of the Company, exchangeable into 8% subordinated
              convertible debentures.  The preferred stock and debentures
              are convertible into shares of the Company's common stock for
              a period of four years and are convertible in years one and
              two at $.75 per share, year three at $1.25 and thereafter at
              $2.00.

         (b)  Upon closing of the private placement, the Company
              contributed approximately $2,700,000 as a capital
              contribution to Chase.

                   June 30, 1995 and 1996 is unaudited)

NOTE B - REORGANIZATION PLAN - Continued

         (c)  TGC liquidated its wholly-owned 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 will retain the manufacturing facility of Old Chase
              located in Portland, Oregon.  TGC intends to sell the
              facility, and the sales proceeds will be contributed to New
              Chase to be applied against the mortgage indebtedness
              currently encumbering such facility.

         (d)  During June 1996, the Board of Directors approved the 
              spin-off of New Chase whereby all of the Shares of New Chase
              will 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 distribution
              date of the New Chase common stock is currently anticipated
              to occur in October, 1996.

Accordingly, the operations of Chase have been classified as discontinued
in the accompanying consolidated financial statements.  The net assets and
liabilities relating to the discontinued operations have been segregated on
the consolidated balance sheets as of December 31, 1995 and June 30, 1996,
and are as follows:

NOTE I - FINANCIAL INSTRUMENTS

   The following methods and assumptions were used to estimate the fair
   value of financial instruments:

   Cash

   The carrying amount of cash approximates fair value due to the short
   term nature of the account.

   Long-term Obligations

   Fair value for long-term debt was estimated using current rates offered
   to the Company for debt with similar maturities.

   The estimated fair values of the Company's financial instruments at
   December 31, 1995 are as follows:

                    STATEMENT OF RESOLUTION ESTABLISHING 
           SERIES C 8% CONVERTIBLE EXCHANGEABLE PREFERRED STOCK OF

                            TGC INDUSTRIES, INC.

     Pursuant to the provisions of Article 2.13 of the Texas Business

     RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by Article 4.b of the Corporation's
Certificate of Restated Articles of Incorporation, as amended, a series of
preferred stock of the Corporation be, and it is hereby, created out of the

such series to be designated Series C 8% Convertible Exchangeable Preferred
Stock (the "Preferred Stock"), to consist of 1,250,000 shares, to be
offered in a private placement at $5.00 per share, of which the preferences
and relative and other rights, and the qualifications, limitations or
restrictions thereof, shall be (in addition to those set forth in the
Corporation's Certificate of Incorporation, as amended) as follows:

     1.   Certain Definitions.  Unless the context otherwise requires, the
terms defined in this paragraph 1 shall have, for all purposes of this
resolution, the meanings herein specified.

     Common Stock.  The term "Common Stock" shall mean all shares now or
hereafter authorized of any class of Common Stock of the Corporation and
any other stock of the Corporation, howsoever designated, authorized after
the Issue Date, which has the right (subject always to prior rights of any

                                                                      A-1
class or series of preferred stock) to participate in the distribution of
the assets and earnings of the Corporation without limit as to per share
amount.

     Conversion Date.  The term "Conversion Date" shall have the meaning
set forth in subparagraph 3(e) below.

     Conversion Ratio.  The term "Conversion Ratio" shall mean the ratio
used to determine the number of shares of Common Stock deliverable upon
conversion of the Preferred Stock, subject to adjustment in accordance with
the provisions of paragraph 3 below.

     Issue Date.  The term "Issue Date" shall mean the date that shares of
Preferred Stock are first issued by the Corporation.

     Market Price.  The term "Market Price" shall have the meaning set
forth in subparagraph 3(h) below.

     Private Placement Memorandum.  The term "Private Placement Memorandum"
shall mean the Confidential Private Placement Memorandum dated May 15,
1996, as amended, and related documents, pursuant to which the Corporation
is offering the Preferred Stock.

     Subsidiary.  The term "Subsidiary" shall mean any corporation of which
shares of stock possessing at least a majority of the general voting power
in electing the board of directors are, at the times as of which any
determination is being made, owned by the Corporation, whether directly or
indirectly through one or more Subsidiaries.

     2.   Dividends.  The Preferred Stock shall have the following dividend
rights:

          (a)  Declaration of Dividends.  The holders of shares of
Preferred Stock shall be entitled to receive cumulative cash dividends,
when and as declared by the Board of Directors out of funds legally
available therefor, at a rate of eight percent (8%) per annum and no more
($0.40 per share per annum based on a price per share of $5.00), before any

                                                                      A-2
dividend or distribution in cash or other property (other than dividends
payable in stock ranking junior to the Preferred Stock as to dividends and
upon liquidation, dissolution or winding-up) on any class or series of
stock of the Corporation ranking junior to the Preferred Stock as to
dividends or on liquidation, dissolution or winding-up shall be declared or
paid or set apart for payment.

          (b)  Payment of Dividends.  Dividends on the Preferred Stock
shall be payable, when and as declared by the Board of Directors on January
1 and July 1 of each year, commencing January 1, 1997 (each such date being
hereinafter individually a "Dividend Payment Date" and collectively the
"Dividend Payment Dates"), except that if such date is a Saturday, Sunday
or legal holiday then such dividend shall be payable on the first
immediately preceding calendar day which is not a Saturday, Sunday or legal
holiday, to holders of record as they appear on the books of the
Corporation on such respective dates, not exceeding sixty days preceding
such Dividend Payment Date, as may be determined by the Board of Directors
in advance of the payment of each particular dividend.  Dividends in
arrears may be declared and paid at any time, without reference to any
regular Dividend Payment Date, to holders of record on such date as may be
fixed by the Board of Directors of the Corporation.  Dividends declared and
paid in arrears shall be applied first to the earliest dividend period or
periods for which any dividends remain outstanding.  The amount of
dividends payable per share of this Series for each dividend period shall
be computed by dividing the annual rate of eight percent (8%) by two (2). 
Dividends payable on this Series for the initial period and for any period
less than a full quarterly period shall be computed on the basis of a
360-day year of twelve 30-day months.

          (c)  Dividends Cumulative.  Preferred Stock shall be cumulative
and accrue from and after the date of original issuance thereof, whether or
not declared by the Board of Directors.  Accrued dividends shall not bear
interest.

          (d)  Dividend Restriction.  No cash dividend may be declared on
any other class or series of stock ranking on a parity with the Preferred
Stock as to dividends in respect of any dividend period unless there shall

                                                                      A-3
also be or have been declared on the Preferred Stock like dividends for all
quarterly periods coinciding with or ending before such semi-annual period,
ratably in proportion to the respective annual dividend rates fixed
therefor.

     3.   Conversion Rights.  The Preferred Stock shall be convertible into
Shares of Common Stock as follows:

          (a)  Conversion Right.  The holder of any shares of Preferred
Stock shall have the right, at such holder's option, at any time to convert
any of such shares of Preferred Stock into fully paid and nonassessable
shares of Common Stock at the Conversion Ratio provided for in subparagraph
3(d) below by surrendering shares of Preferred Stock for conversion in
accordance with subparagraph 3(e) below.

          (b)  Continuance of Conversion Right.  The Conversion Right set
forth above will continue so long as such Preferred Stock is outstanding
with respect to any stock not (i) redeemed in accordance with the terms of
paragraph 7, or (ii) exchanged pursuant to the terms of paragraph 9, prior
to the exercise of such conversion right.

          (c)  Surrender of Shares on Exercise of Conversion Right.  In the
event that any holder of shares of Preferred Stock surrenders such shares
for conversion, such holder will be issued the number of shares of Common
Stock to which such holder is entitled pursuant to the provisions of
subparagraph 3(d) in the manner provided for in subparagraph 3(e).  The
shares of Preferred Stock deemed to have been surrendered will have the
status described in paragraph 11 below.

          (d)  Conversion Ratio.  Each share of Preferred Stock may, at the
discretion of the holder thereof, be converted into shares of Common Stock
of the Corporation at the conversion price per share of (i) prior to the
close of business on July 1, 1998, the conversion price per share of Common
Stock of Seventy-Five Cents ($0.75), (ii) after July 1, 1998 and prior to
the close of business on July 1, 1999, the conversion price per share of
Common Stock of One Dollar and Twenty-Five Cents ($1.25), and (iii)
thereafter, the conversion price per share of Common Stock of Two Dollars

                                                                      A-4
($2.00), as such conversion price may be adjusted and readjusted from time
to time in accordance with subparagraph 3(g) hereof (such conversion price,
as adjusted and readjusted and in effect at any time, being herein called
the "Conversion Price" or the "Conversion Ratio"), into the number of fully
paid and non- assessable shares of Common Stock determined by dividing (x)
the $5.00 per share price of the Preferred Stock to be so converted by (y)
the Conversion Price in effect at the time of such conversion.  The
Conversion Ratios referred to above will be subject to adjustment as set
forth in subparagraph 3(g). 

          (e)  Mechanics of Conversion.  The holder of any shares of
Preferred Stock may exercise the conversion right specified in subparagraph
3(a) by surrendering to the Corporation or any transfer agent of the
Corporation the certificate or certificates for the shares to be converted,
accompanied by written notice specifying the number of shares to be
converted. Conversion shall be deemed to have been effected upon receipt of
the certificate or certificates for the shares to be converted accompanied
by written notice of election to convert specifying the number of shares to
be converted.  The date of such receipt is referred to herein as the
"Conversion Date."  As promptly as practicable thereafter (and after
surrender of the certificate or certificates representing shares of
Preferred Stock to the Corporation or any transfer agent of the
Corporation) the Corporation shall issue and deliver to or upon the written
order of such holder a certificate or certificates for the number of full
shares of Common Stock to which such holder is entitled and a check or cash
with respect to any fractional interest in a share of Common Stock as
provided in subparagraph 3(f).  The person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have
become a holder of record of such Common Stock on the applicable Conversion
Date. Upon conversion of only a portion of the number of shares covered by
a certificate representing shares of Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written
order of the holder of the certificate so surrendered for conversion, at
the expense of the Corporation, a new certificate covering the number of
shares of Preferred Stock representing the unconverted portion of the
certificate so surrendered.

                                                                      A-5

          (f)  Fractional Shares.  No fractional Shares or scrip shall be
issued upon conversion of shares of Preferred Stock. If more than one share
of Preferred Stock shall be surrendered for conversion at any one time by
the same holder, the number of shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number
of shares of Preferred Stock so surrendered. Instead of any fractional
shares which would otherwise be issuable upon conversion of any shares of
Preferred Stock, the Corporation shall pay a cash adjustment in respect of
such fractional interest in an amount equal to that fractional interest of
the then Current Market Price.

          (g)  Conversion Ratio Adjustments.  The Conversion Ratio shall be
subject to adjustment from time to time as follows:

               (i)  Stock Dividends, Subdivisions, Reclassifications or
Combinations.  If the Corporation shall (x) declare a dividend or make a
distribution on its Common Stock in shares of its Common Stock, (y)
subdivide or reclassify the outstanding shares of Common Stock into a
greater number of shares, or (z) combine or reclassify the outstanding
Common Stock into a smaller number of shares, the Conversion Ratio in
effect at the time of the record date for such dividend or distribution or
the effective date of such subdivision, combination or reclassification
shall be proportionately adjusted so that the holder of any shares of
Preferred Stock surrendered for conversion after such date shall be
entitled to receive the number of shares of Common Stock which he would
have owned or been entitled to receive had such Preferred Stock been
converted immediately prior to such date. Successive adjustments in the
Conversion Ratio shall be made whenever any event specified above shall
occur.

              (ii)  Other Distributions.  In case the Corporation shall fix
a record date for the making of a distribution to all holders of shares of
its Common Stock (w) of shares of any class other than its Common Stock or
(x) of evidence of indebtedness of the Corporation or any Subsidiary or (y)
of assets (excluding cash dividends or distributions, and dividends or
distributions referred to in subparagraph 3(g)(i) above), or (z) of rights
or warrants, in each such case the Conversion Ratio in effect immediately

                                                                      A-6
prior thereto shall be immediately thereafter proportionately adjusted for
such distribution so that the holder of Preferred Stock would be entitled
to receive the fair market value (as determined by the Board of Directors,
whose determination shall be conclusive) of what he would have been
entitled to receive had such Preferred Stock been converted prior to such
distribution.  Such adjustment shall be made successively whenever such a
record date is fixed. In the event that such distribution is not so made,
the Conversion Ratio then in effect shall be readjusted, effective as of
the date when the Board of Directors determines not to distribute such
shares, evidences of indebtedness, assets, rights or warrants, as the case
may be, to the Conversion Ratio which would then be in effect if such
record date had not been fixed.

             (iii)  Consolidation, Merger, Sale, Lease or Conveyance.  In
case of any consolidation with or merger of the Corporation with or into
another corporation or entity, or in case of any sale, lease or conveyance
to another corporation or entity of the assets of the Corporation as an
entirety or substantially as an entirety, each share of Preferred Stock
shall after the date of such consolidation, merger, sale, lease or
conveyance be convertible into the number of shares of stock or other
securities or property (including cash) to which the shares of Common Stock
issuable (at the time of such consolidation, merger, sale, lease or
conveyance) upon conversion of such share of Preferred Stock would have
been entitled upon such consolidation, merger, sale, lease or conveyance;
and in any such case, if necessary, the provisions set forth herein with
respect to the rights and interests thereafter of the holders of the shares
of Preferred Stock shall be appropriately adjusted so as to be applicable,
as nearly as may reasonably be, to any shares of stock or other securities
or property thereafter deliverable on the conversion of the shares of
Preferred Stock.

          (h)  Market Price.  The Market Price shall mean the daily closing
price per Share (as adjusted for any stock dividend, split, combination or
reclassification that took effect during the period under consideration).
The closing price for each day shall be the last reported sale price or, in
case no such reported sale takes place on such day, the average of the last
closing bid and asked prices, in either case on the principal national

                                                                      A-7
securities exchange on which the Common Stock is listed or admitted to
trading, or if not listed or admitted to trading on any national securities
exchange, the closing sale price for such day reported by NASDAQ, if the
Common Stock is traded over-the-counter and quoted in the National Market
System, or if the Common Stock is so traded, but not so quoted, the average
of the closing reported bid and asked prices of the Common Stock as
reported by NASDAQ or any comparable system or, if the Common Stock is not
listed on NASDAQ or any comparable system, the average of the closing bid
and asked prices as furnished by two members of the National Association of
Securities Dealers, Inc. selected from time to time by the Corporation for
that purpose. If the Common Stock is not traded in such manner that the
quotations referred to above are available, Market Price per Share shall be
deemed to be the fair value as determined by the Board of Directors,
irrespective of any accounting treatment.

          (i)  Statement Regarding Adjustments.  Whenever the Conversion
Ratio shall be adjusted as provided in subparagraph 3(g), the Corporation
shall forthwith file, at the office of any transfer agent for the Preferred
Stock and at the principal office of the Corporation, a statement showing
in detail the facts requiring such adjustment and the Conversion Ratio that
shall be in effect after such adjustment, and the Corporation shall also
cause a copy of such statement to be sent by mail, first class postage
prepaid, to each holder of shares of Preferred Stock at its address
appearing on the Corporation's records. Where appropriate, such copy may be
given in advance and may be included as part of a notice required to be
mailed under the provisions of subparagraph 3(j).

          (j)  Notice to Holders.  In the event the Corporation shall
propose to take any action of the type described in clause (i), (ii) or
(iii) of subparagraph 3(g), the Corporation shall give notice to each
holder of shares of Preferred Stock, in the manner set forth in
subparagraph 3(i), which notice shall specify the record date, if any, with
respect to any such action and the approximate date on which such action is
to take place. Such notice shall also set forth such facts with respect
thereto as shall be reasonably necessary to indicate the effect of such
action (to the extent such effect may be known at the date of such notice)
on the Conversion Ratio and the number, kind or class of shares which shall

                                                                      A-8
be deliverable upon conversion of shares of Preferred Stock. In the case of
any action which would require the fixing of a record date, such notice
shall be given at least 10 days prior to the date so fixed, and in case of
all other action, such notice shall be given at least 15 days prior to the
taking of such proposed action. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of any such action.

          (k)  Treasury Stock.  For the purposes of this paragraph 3, the
sale or other disposition of any Common Stock theretofore held in the
Corporation's treasury shall be deemed to be an issuance thereof.

          (l)  Costs.  The Corporation shall pay all documentary, stamp,
transfer or other transactional taxes attributable to the issuance or
delivery of shares of Common Stock upon conversion of any shares of
Preferred Stock; provided that the Corporation shall not be required to pay
any taxes which may be payable in respect of any transfer involved in the
issuance or delivery of any certificate for such shares in a name other
than that of the holder of the shares of Preferred Stock in respect of
which such shares are being issued.

          (m)  Reservation of Shares.  The Corporation shall reserve at all
times so long as any shares of Preferred Stock remain outstanding, free
from preemptive rights, out of its treasury stock (if applicable) or its
authorized but unissued shares of Common Stock, or both, solely for the
purpose of effecting the conversion of the shares of Preferred Stock,
sufficient shares of Common Stock to provide for the conversion of all
outstanding shares of Preferred Stock.

          (n)  Approvals.  If any shares of Common Stock to be reserved for
the purpose of conversion of shares of Preferred Stock require registration
with or approval of any governmental authority under any Federal or state
law before such shares may be validly issued or delivered, then the
Corporation will in good faith and as expeditiously as possible endeavor to
secure such registration or approval, as the case may be. If, and so long
as, any shares of Common Stock into which the shares of Preferred Stock are
then convertible are listed on any national securities exchange, the
Corporation will, if permitted by the rules of such exchange, list and keep

                                                                      A-9
listed on such exchange, upon official notice of issuance, all such shares
issuable upon conversion.

          (o)  Valid Issuance.  All shares of Common Stock which may be
issued upon conversion of the shares of Preferred Stock will upon issuance
by the Corporation be duly and validly issued, fully paid and nonassessable
and free from all taxes, liens and charges with respect to the issuance
thereof, and the Corporation shall take no action which will cause a
contrary result.

     4.   Voting Rights.  The holders of the shares of the Preferred Stock
will be entitled to one vote per share of Preferred Stock held by them to
vote upon all matters which the holders of shares of the Company's Common
Stock shall have the right to vote.  In all cases, as a matter of law,
where the holders of shares of Preferred Stock shall have the right to vote
separately as a class, such holders will also be entitled to one vote per
share of Preferred Stock held by them.

     The affirmative vote or consent of the holders of at least two-thirds
of the outstanding shares of the Preferred Stock, voting as a class, will
be required to (i) authorize, create or issue, or increase the authorized
or issued amount of, shares of any class or series of stock ranking prior
to the Preferred Stock, either as to dividends or upon liquidation, or (ii)
amend, alter or repeal (whether by merger, consolidation or otherwise) any
provisions of the Company's Articles of Incorporation or of the Statement
of Resolution establishing this series of Preferred Stock so as to
materially and adversely affect the preferences, special rights or powers
of the Preferred Stock; provided, however, that any increase in the
authorized preferred stock or the creation and issuance of any other series
of preferred stock ranking on a parity with or junior to the Preferred
Stock shall not be deemed to materially and adversely affect such
preferences, special rights or powers.

     5.   Liquidation Rights.  Upon the dissolution, liquidation or winding
up of the Corporation, whether voluntary or involuntary, the holders of the
shares of this series of Preferred Stock shall be entitled to receive,
before any payment or distribution of the assets of the Corporation or

                                                                      A-10
proceeds thereof (whether capital or surplus) shall be made to or set apart
for the holders of the Common Stock or any other class or series of stock
ranking junior to the shares of this series of Preferred Stock upon
liquidation, the amount of $5.00 per share, plus a sum equal to all
dividends on such shares (whether or not earned or declared) accrued and
unpaid thereon to the date of final distribution, but such holders shall
not be entitled to any further payment.  If, upon any liquidation,
dissolution or winding-up of the Corporation, the assets of the
Corporation, or proceeds thereof, distributable among the holders of shares
of the Preferred Stock and any other class or series of preferred stock
ranking on a parity with the Preferred Stock as to payments upon
liquidation, dissolution or winding-up shall be insufficient to pay in full
the preferential amount aforesaid, then such assets or the proceeds thereof
shall be distributed among such holders ratably in accordance with the
respective amounts which would be payable on such shares if all amounts
payable thereon were paid in full.  For the purposes of this paragraph 5,
the voluntary sale, conveyance, lease, exchange or transfer (for cash,
shares of stock, securities or other consideration) of all or substantially
all the property or assets of the Corporation to, or a consolidation or
merger of the Corporation with, one or more corporations (whether or not
the Corporation is the corporation surviving such consolidation or merger)
shall not be deemed to be a liquidation, dissolution or winding-up,
voluntary or involuntary.

     6.   Registration Rights.   

          (a)  Registration on Request.  Upon the written request of any
holder or holders of at least 25% in the aggregate number of shares of the
Preferred Stock and/or shares of Common Stock ("Shares") issued upon
conversion of such Preferred Stock (provided that in computing such 25%
amount the number of shares of Preferred Stock and Common Stock shall be
weighted proportionately taking into account the Conversion Ratio with
respect to which such shares of Common Stock were issued upon conversion),
which request shall state the intended method of disposition by such holder
or holders and shall request that the Company effect the registration of
all or part of such Shares, or the Shares issuable upon the conversion of
such Preferred Stock, or both, under the Securities Act of 1933, as amended

                                                                      A-11
(the "Act"), the Company will promptly give written notice of such
requested registration to all holders of outstanding Preferred Stock and
Shares, and thereupon will use its best efforts to effect the registration
under the Act of:

     (i)  the Shares which the Company has been so requested to register,
     for disposition in accordance with the intended method of disposition
     stated in such request, and

     (ii) all other outstanding Shares, or Shares issuable upon the
     conversion of Preferred Stock, the holders of which shall have made
     written request (stating the intended method of disposition of such
     securities by such holders) to the Company for registration thereof
     within thirty (30) days after the receipt of such written notice from
     the Company,

all to the extent requisite to permit the disposition (in accordance with
the intended methods thereof as aforesaid) by the holders of the Shares so
registered and to maintain such registration in effect for a period of
twenty-four (24) months from the closing of the private placement under the
Private Placement Memorandum; provided, that the Company shall not be
required to register or use its best efforts to effect any registration of
Shares under the Act pursuant to this paragraph 6(a) more than once. 

     The Company shall have no obligation to register or use its best
efforts to effect any registration of Shares under the Act pursuant to this
paragraph 6 which would be in conflict with the obligations of any holder
or holders of Preferred Stock and/or Shares under any confidentiality
agreement between such holder or holders and the Company entered into in
connection with the offering of the Preferred Stock to such holder or
holders.

          (b)  Incidental Registration.  If the Company at any time
proposes to register any of its securities under the Act (otherwise than
pursuant to paragraph 6(a) and other than a registration on Form S-8, or
the form, if any, which supplants such Form), it will at such time give
written notice to all holders of outstanding Preferred Stock and Shares of

                                                                      A-12
its intention to do so and, upon the written request of any such holder
made within thirty (30) days after the receipt of any such notice (which
request shall specify the Shares intended to be disposed of by such holder
and state the intended method of disposition thereof), the Company will use
its best efforts to cause all such outstanding Shares, or Shares issuable
upon the conversion of Preferred Stock, the holders of which shall have so
requested the registration thereof, to be registered under the Act to the
extent requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Shares so registered; provided that,
if in the good faith judgment of the managing underwriter or underwriters
of a then proposed public offering of the Company's securities, such
registration of such Shares would materially and adversely affect such
public offering, then in such event the number of Shares and other
securities to be registered by the Company shall each be proportionally
reduced to such number as shall be acceptable to the managing underwriter.

          (c)  Registration Procedures.  If and whenever the Company is
required to use its best efforts to effect or cause the registration of any
Shares under the Act as provided in this paragraph 6, the Company will, as
expeditiously as possible:

     (i)  prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement with respect to such Shares and
     use its best efforts to cause such registration statement to become
     effective;

     (ii) prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for such period not exceeding twenty-four (24)
     months from the closing of the private placement under the Private
     Placement Memorandum as may be necessary to comply with the provisions
     of the Act with respect to the disposition of all Shares covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the seller or sellers thereof set
     forth in such registration statement;


                                                                      A-13

     (iii) furnish to each seller of such Shares such number of copies of
     such registration statement and of each such amendment and supplement
     thereto (in each case including all exhibits), such number of copies
     of the prospectus included in such registration statement (including
     each preliminary prospectus and, if any seller shall so request, a
     summary prospectus), in conformity with the requirements of the Act,
     and such other documents, as such seller may reasonably request in
     order to facilitate the disposition of the Shares owned by such
     seller;

     (iv) use its best efforts to register or qualify such Shares covered
     by such registration statement under such other securities or blue sky
     laws of such jurisdictions as each seller shall reasonably request and
     as agreed to by the Corporation, and do any and all other acts and
     things which may be reasonably necessary or advisable to enable such
     seller to consummate the disposition in such jurisdictions of the
     Shares owned by such seller; and

     (v)  notify each seller of any such Shares covered by such
     registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act within the period mentioned
     in subdivision (b) of this paragraph 6(c), of the happening of any
     event as a result of which the prospectus included in such
     registration statement, as then in effect, includes an untrue
     statement of a material fact or omits to state any material fact
     required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then
     existing, and at the request of any such seller prepare and furnish to
     such seller a reasonable number of copies of a supplement to or an
     amendment of such prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such Shares, such prospectus
     shall not include an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing.

           (d)  Registration Expenses.    All expenses incident to the

                                                                      A-14
Company's performance of or compliance with this paragraph 6, including,
without limitation, all registration and filing fees, fees and expenses of
complying with securities or blue sky laws, printing expenses and fees and
disbursements of counsel for the Company and of independent pubic
accountants, but excluding underwriting commissions and discounts, shall be
borne by the Company.  

          (e)  Indemnification.  

     (i)  In the event of any registration of any Restricted Shares under
     the Act pursuant to this paragraph 6, the Company will, to the extent
     permitted by law, indemnify and hold harmless the seller of such
     Shares and each underwriter of such securities and each other person,
     if any, who controls such seller or underwriter within the meaning of
     the Act, against any losses, claims, damages, or liabilities, joint or
     several, to which such seller or underwriter or controlling person may
     become subject, under the Act or otherwise, insofar as such losses,
     claims, damages, or liabilities (or actions in respect thereof) arise
     out of or are based upon (x) any untrue statement or alleged untrue
     statement of any material fact contained, on the effective date
     thereof, in any registration statement under which such securities
     were registered under the Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto,
     or (y) any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and the Company will reimburse such seller and
     each such underwriter and each such controlling person for any legal
     or any other expenses reasonably incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability, or
     action, provided that the Company shall not be liable in any such case
     to the extent that any such loss, claim, damage, or liability arises
     out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in such registration
     statement, any such preliminary prospectus, final prospectus,
     amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company through an instrument
     duly executed by such seller or underwriter specifically for use in

                                                                      A-15

     the preparation thereof.

     (ii) The Company may require, as a condition to including any Shares
     in any registration statement filed pursuant to paragraph 6(c), that
     the Company shall have received an undertaking satisfactory to it from
     the prospective seller of such Shares and from each underwriter of
     such  Shares, to indemnify and hold harmless (in the same manner and
     to the same extent as set forth in paragraph 6(e)(i)) the Company,
     each director of the Company, each officer of the Company who shall
     sign such registration statement and any person who controls the
     Company within the meaning of the Act, with respect to any statement
     or omission from such registration statement, any preliminary
     prospectus or final prospectus contained therein, or any amendment or
     supplement thereto, if such statement or omission was made in reliance
     upon and in conformity with written information furnished to the
     Company through an instrument duly executed by such seller or
     underwriter specifically for use in the preparation of such
     registration statement, preliminary prospectus, final prospectus,
     amendment, or supplement.

     (iii) Promptly after receipt by an indemnified party of notice of
     the commencement of any action involving a claim referred to in the
     preceding subparagraphs of this paragraph 6(e), such indemnified party
     will, if a claim in respect thereof is to be made against an
     indemnifying party, give written notice to the latter of the
     commencement of such action, provided that the failure of any
     indemnified party to give notice as provided therein shall not relieve
     the indemnifying party of its obligations under the preceding
     subdivisions of this paragraph 6(e). In case any such action is
     brought against an indemnified party, the indemnifying party will be
     entitled to participate in and to assume the defense thereof, jointly
     with any other indemnifying party similarly notified to the extent
     that it may wish, with counsel reasonably satisfactory to such
     indemnified party, and after notice from the indemnifying party to
     such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified
     party for any legal or other expenses subsequently incurred by the

                                                                      A-16

     latter in connection with the defense thereof.  No indemnifying party,
     in the defense of any such claim or litigation, shall, except with the
     consent of each indemnified party, consent to entry of any judgment or
     enter into any settlement which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in respect to such
     claim or litigation.

     7.   Redemption Rights.  

          (a) Company's Redemption Option.  Except for any redemption which
the Company would be prohibited from effecting under applicable law, and
provided the shares of Preferred Stock of a holder have not earlier been
converted or exchanged in accordance with the provisions hereof, the shares
of Preferred Stock may be redeemed by the Company, in whole or in part, at
the option of the Company upon written notice by the Company to the holders
of Preferred Stock at any time after July 1, 2000, in the event that the
Preferred Stock of one or more holders has not been converted or exchanged
pursuant to the terms hereof on or before such date.  The Company shall
redeem each share of Preferred Stock of such holders within thirty (30)
days of the Company's delivery of the above notice to such holders and such
holders shall surrender the certificate(s) representing such shares of
Preferred Stock.  For any partial redemptions the Company shall redeem
shares in proportion to the number of shares held by each holder.  The
redemption amount shall be $5.00 per share, plus in each case accrued and
unpaid dividends thereon to the date of payment of such amount (the total
sum so payable on any such redemption being herein referred to as the
"redemption price"); provided, however, that for any such redemption which
is effected (i) on or after July 1, 2001 but prior to July 1, 2002, a
premium of ten percent (10%) of the per share amount of such Preferred
Stock shall be paid per share (i.e. $0.50 per share of Preferred Stock),
(ii) on or after July 1, 2002 but prior to July 1, 2003, a premium of 20%
per share (i.e. $1.00 per share); (iii) on or after July 1, 2003 but prior
to July 1, 2004, a premium of 30% per share (i.e. $1.50 per share); (iv) on
or after July 1, 2004 but prior to July 1, 2005, a premium of 40% per share
(i.e. $2.00 per share); and on or after July 1, 2005 a premium of 50% per
share (i.e. $2.50 per share).

                                                                      A-17

          (b)  Redemption Notice.  Notice of any redemption pursuant to
this paragraph 7 shall be mailed to the party or parties required to
receive such notice at the principal office or residence address for such
party or parties.  Each such notice shall state: (1) the election of the
redemption option and the facts which give rise to such option; and (2) the
number of shares of Preferred Stock which are being elected to be redeemed. 
From and after the date of the Company's payment of the redemption price to
such holder or holders in accordance with such redemption notice (the
"redemption date"), notwithstanding that any certificates for such shares
shall not have been surrendered for cancellation, the shares represented
thereby shall no longer be deemed outstanding, the rights to receive
dividends and distributions shall cease to accrue from and after the
redemption date, and all rights of such holder or holders of the shares of
Preferred Stock as a stockholder of the Corporation with respect to such
shares, shall cease and terminate.
            
     8.   Exclusion of Other Rights.  Except as may otherwise be required
by law, the shares of Preferred Stock shall not have any preferences or
relative, participating, optional or other special rights, other than those
specifically set forth in this resolution (as such resolution may be
amended from time to time) and in the Corporation's Certificate of
Incorporation.  The shares of Preferred Stock shall have no preemptive or
subscription rights.

     9.   Exchange.  The shares of Preferred Stock shall be subject to the
following exchange provisions:

          (a)  Exchange for Debentures.  Shares of Preferred Stock are
exchangeable in whole by the Corporation, at its sole option, at any time
for the Corporation's 8% Subordinated Convertible Debentures, Series A due
the later of July 1, 2000 or two years from the date of exchange, as
described in the Corporation's Private Placement Memorandum; provided that
on or prior to the date of exchange the Corporation shall have paid to the
holders of outstanding shares of Preferred Stock all accumulated and unpaid
dividends to the date of exchange; and further provided that the
Corporation may not exercise such exchange option prior to January 1, 1998. 
Holders of outstanding shares of Preferred Stock will be entitled to

                                                                      A-18
receive $5.00 principal amount of Debentures in exchange for each share of
Preferred Stock held by them at the time of exchange; provided, however,
that for any such exchange which is effected on or after July 1, 2001, the
principal amount of Debentures exchanged for each share of Preferred Stock
shall include a premium as follows: (i) on or after July 1, 2001 but prior
to July 1, 2002, a premium of ten percent (10%) of the principal amount of
the Debenture per share (i.e. $0.50 per share of Preferred Stock, equal to
a Debenture in the amount of $5.50 per share), (ii) on or after July 1,
2002 but prior to July 1, 2003, a premium of 20% per share (i.e. $1.00 per
share, equal to a Debenture in the amount of $6.00 per share); (iii) on or
after July 1, 2003 but prior to July 1, 2004, a premium of 30% per share
(i.e. $1.50 per share, equal to a Debenture in the amount of $6.50 per
share); (iv) on or after July 1, 2004 but prior to July 1, 2005, a premium
of 40% per share (i.e. $2.00 per share, equal to a Debenture in the amount
of $7.00 per share); and on or after July 1, 2005 a premium of 50% per
share (i.e. $2.50 per share, equal to a Debenture in the amount of $7.50
per share).  The Corporation will mail to each holder of record of the
shares of Preferred Stock written notice of its intention to exchange no
less than thirty (30) nor more than sixty (60) days prior to the date fixed
for the exchange (the "exchange date").  Each such notice shall state:  (i)
the exchange date, (ii) the place or places where certificates for such
shares are to be surrendered for exchange into Debentures and (iii) that
dividends on the shares to be exchanged will cease to accrue on such
exchange date.  The terms of the Debentures are set forth in the Private
Placement Memorandum and "Exhibit B" thereto.  The Corporation will pay
interest on the Debentures at the rate and on the dates specified in such
Debentures from the exchange date.

          (b)  Status of Preferred Stock Following Exchange.  If notice has
been mailed as aforesaid, from and after the exchange date (unless default
shall be made by the Corporation in issuing Debentures in exchange for
shares of Preferred Stock or in making the final dividend payment on the
outstanding shares of Preferred Stock on the exchange date), dividends on
the shares of Preferred Stock shall cease to accrue, and such shares shall
no longer be deemed to be issued and outstanding, and all rights of the
holders thereof as stockholders of the Corporation (except the right to
receive from the Corporation the Debentures) shall cease and terminate. 

                                                                      A-19
Upon surrender in accordance with said notice of the certificates for any
shares so exchanged (properly endorsed or assigned for transfer, if the
Board of Directors shall so require and the notice shall so state), such
shares shall be exchanged by the Corporation into Debentures as aforesaid
and the holders thereof shall sign the Debenture Agreement with respect to
such Debentures in the form attached as Exhibit "B" to the Private
Placement Memorandum.

          (c)  Conversion Price for Debentures.  The conversion price per
share equivalent to the Conversion Ratio on any exchange date shall be the
initial conversion price for the Debentures.

     10.  Severability of Provisions.  If any right, preference or
limitation of the Preferred Stock set forth in this resolution (as such
resolution may be amended from time to time) is invalid, unlawful or
incapable of being enforced by reason of any rule or law or public policy,
all other rights, preferences and limitations set forth in this resolution
(as so amended) which can be given effect without the invalid, unlawful or
unenforceable right, preference or limitation herein set forth shall be
deemed enforceable and not dependent upon any other such right, preference
or limitation unless so expressed herein.

     11.  Status of Reacquired Shares.  Shares of Preferred Stock which
have been issued and reacquired in any manner shall (upon compliance with
any applicable provisions of the laws of the State of Texas) have the
status of authorized and unissued shares of Preferred Stock issuable in
series undesignated as to series and may be redesignated and reissued.

in each such case, the holders of the Subordinated Indebtedness shall be
subrogated to any rights of any holders of Superior Indebtedness to receive
further payments or distributions in respect of or applicable to the
Superior Indebtedness.

Subordinated Indebtedness is declared due and payable because of the
occurrence of a default or event of default under circumstances when the
terms of Section 7.03 are not applicable, the holders of such Subordinated
Indebtedness shall not be entitled to receive payment or distribution in
respect thereof until all Superior Indebtedness at the time outstanding
shall have been paid in full; provided, however, that the holders of the
Subordinated Indebtedness shall continue to be entitled to receive (i)

                                                                      B-15

or event of default, the Company will give prompt notice in writing of such
happening to each holder of Superior Indebtedness.

     Section 7.08.  Subordination Not Affected, etc.  The terms of this
Article VII, the subordination effected hereby, and the rights of the
holders of the Superior Indebtedness shall not be affected by (a) any
amendment of or addition or supplement to any Superior Indebtedness or any
instrument or agreement relating thereto, (b) any exercise or non-exercise
of any right, power, or remedy under or in respect of any Superior
Indebtedness or any instrument or agreement relating thereto, or (c) any
waiver, consent, release, indulgence, extension, renewal, modification,
delay, or other action, inaction or omission, in respect of any Superior
Indebtedness or any instrument or agreement relating thereto or any
security therefor or guaranty thereof, whether or not any holder of any
Subordinated Indebtedness shall have had notice or knowledge of any of the
foregoing.

     Section 7.09.  Obligations Unimpaired.  No present or future holder of
Superior Indebtedness shall be prejudiced in the right to enforce
subordination of the Subordinated Indebtedness by any act or failure to act
on the part of the Company.  The provisions of this Article VII are solely
for the purpose of defining the relative rights of the holders of Superior
Indebtedness on the one hand and the holders of Subordinated Indebtedness
on the other hand, and nothing in this Article VII shall (a) impair as
between the Company and the holder of any Subordinated Indebtedness the
obligation of the Company, which is unconditional and absolute, to pay to
the holder thereof the principal, premium, if any, and interest thereon in
accordance with the terms thereof, or (b) prevent the holder of any
Subordinated Indebtedness from exercising all remedies otherwise permitted
by applicable law under this Agreement, subject to the rights, if any,

                                                                      B-16

any Debenture or any portion thereof may, at the election of the holder
thereof, at any time after the date of such Debenture be converted into
shares of Common Stock at the conversion price per share of (a) prior to
the close of business on July 1, 1998, the conversion price per share of
Common Stock of Seventy-Five Cents ($0.75), (b) after July 1, 1998 and
prior to the close of business on July 1, 1999, the conversion price per
share of Common Stock of One Dollar and Twenty-Five Cents ($1.25), and (c)
thereafter, the conversion price per share of Common Stock of Two Dollars
($2.00), as such conversion price may be adjusted and readjusted from time
to time in accordance with Section 8.05 hereof (such conversion price, as
so adjusted and readjusted and in effect at any time, being herein called
the Conversion Price), into the number of fully paid and non-assessable
shares of Common Stock determined by dividing (x) the aggregate principal
amount of the Debentures to be so converted by (y) the Conversion Price in
effect at the time of such conversion.

     Section 8.02.  Manner of Conversion; Partial Conversion, etc.  
          
     (a) Any Debenture may be converted in whole or in part by the holder
     thereof by surrender of such Debenture, accompanied by a written
     statement designating the principal amount of such Debenture to be
     converted and stating the name and address of the person in whose name
     certificates for shares of Common Stock are to be registered, at the
     office of the Company specified in or pursuant to Section 15.01.  Upon
     any such partial conversion of a Debenture, the Company at its expense
     will forthwith issue and deliver to or upon the order of the holder
     thereof a new Debenture or Debentures in principal amount equal to the
     unpaid and unconverted principal amount of such surrendered Debenture,
     such new Debenture or Debentures to be dated and to bear interest from

                                                                      B-17

     the date to which interest has been paid on such surrendered
     Debenture.  Each conversion shall be deemed to have been effected as
     of the close of business on the date on which such Debenture shall
     have been so surrendered to such office, and at such time the rights
     of the holder of such Debenture as such shall, to the extent of the
     principal amount thereof converted, cease, and the person or persons
     in whose name or names any certificate or certificates for shares of
     Common Stock shall be issuable upon such conversion shall be deemed to
     have become the holder or holders of record thereof.

     (b)  The Company shall pay all interest on any Debenture or portion of
     any Debenture surrendered for conversion to the date of such
     conversion.

     Section 8.03.  Delivery of Stock Certificates.  As promptly as
practicable after the conversion of any Debenture in full or in part, and
in any event within 20 days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will issue and
deliver to the holder of such Debenture, or as such holder (upon payment by
such holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of full and fractional shares of Common Stock
issuable upon such conversion.

     Section 8.04.  Shares to be Fully Paid; Reservation of Shares. The
Company covenants and agrees that all shares of Common Stock which may be
issued upon conversion of the Debentures will, upon issuance, be fully paid
and non-assessable and free from all taxes, liens, and charges with respect
to the issue thereof; and without limiting the generality of the foregoing,
the Company covenants and agrees that it will from time to time take all
such action as may be requisite to assure that the par value (if any) per
share of the Common Stock is at all times equal to or less than the then
effective purchase price per share of the Common Stock issuable upon
conversion of the Debentures.  The Company further covenants and agrees
that the Company will at all times have authorized, and reserved for the
purpose of issue or transfer upon the conversion of the Debentures, a
sufficient number of shares of its Common Stock to provide for the
conversion of the Debentures.

                                                                      B-18

     Section 8.05.   Conversion Ratio Adjustments.  The Conversion Ratio
shall be subject to adjustment from time to time as follows:

          (a)  Stock Dividends, Subdivisions, Reclassifications or
          Combinations.  If the Corporation shall (i) declare a dividend or
          make a distribution on its Common Stock in shares of its Common
          Stock, (ii) subdivide or reclassify the outstanding shares of
          Common Stock into a greater number of shares, or (iii) combine or
          reclassify the outstanding Common Stock into a smaller number of
          shares, the Conversion Price in effect at the time of the record
          date for such dividend or distribution or the effective date of
          such subdivision, combination or reclassification shall be
          proportionately adjusted so that the holder of any Debentures
          surrendered for conversion after such date shall be entitled to
          receive the number of shares of Common Stock which he would have
          owned or been entitled to receive had such Debentures been
          converted immediately prior to such date.  Successive adjustments
          in the Conversion Ratio shall be made whenever any event
          specified above shall occur.

          (b)  Other Distributions.  In case the Corporation shall fix a
          record date for the making of a distribution to all holders of
          shares of its Common Stock (i) of shares of any class other than
          its Common Stock or (ii) of evidences of indebtedness of the
          Corporation or any Subsidiary or (iii) of assets (excluding cash
          dividends or distributions, and dividends or distributions
          referred to in subparagraph 8.05(a) above), or (iv) of rights or
          warrants, in each such case the Conversion Price in effect
          immediately prior thereto shall be immediately thereafter
          proportionately adjusted for such distribution so that the holder
          of Debentures would be entitled to receive the fair market value
          (as determined by the Board of Directors, whose determination
          shall be conclusive) of what he would have been entitled to
          receive had such Debentures been converted prior to such
          distribution.  Such adjustment shall be made successively
          whenever such a record date is fixed.  In the event that such
          distribution is not so made, the Conversion Price then in effect

                                                                      B-19

          shall be readjusted, effective as of the date when the Board of
          Directors determines not to distribute such shares, evidences of
          indebtedness, assets, rights or warrants, as the case may be, to
          the Conversion Price which would then be in effect if such record
          date had not been fixed.

          (c)  Consolidation, Merger, Sale, Lease or Conveyance.  In case
          of any consolidation with or merger of the Corporation with or
          into another corporation, or in case of any sale, lease or
          conveyance to another corporation of the assets of the
          Corporation as an entirety or substantially as an entirety, the
          Debentures shall after the date of such consolidation, merger,
          sale, lease or conveyance be convertible into the number of
          shares of stock or other securities or property (including cash)
          to which the shares of Common Stock issuable (at the time of such
          consolidation, merger, sale, lease or conveyance) upon conversion
          of such Debenture would have been entitled to upon such
          consolidation, merger, sale, lease or conveyance; and in any such
          case, if necessary, the provisions set forth herein with respect
          to the rights and interests thereafter of the holders of the
          Debentures shall be appropriately adjusted so as to be
          applicable, as nearly as may reasonably be, to any shares of
          stock or other securities or property thereafter deliverable on
          conversion of the Debentures.

     Section 8.06.  Statement Regarding Adjustments.  Whenever the
Conversion Price shall be adjusted as provided in Section 8.05, the
Corporation shall forthwith file, at the principal office of the
Corporation, a statement showing in detail the facts requiring such
adjustment and the Conversion Price that shall be in effect after such
adjustment, and the Corporation shall also cause a copy of such statement
to be sent by mail, first class postage prepaid, to each holder of
Debentures, at its address appearing on the Corporation's records.  Where
appropriate, such copy may be given in advance and may be included as part
of a notice required to be mailed under the provisions of Section 8.07.

     Section 8.07.  Notice to Holders.  In the event the Corporation shall

                                                                      B-20

propose to take any action of the type described in Section 8.05, the
Corporation shall give notice to each holder of Debentures, in the manner
set forth in Section 8.06, which notice shall specify the record date, if
any, with respect to any such action and the approximate date on which such
action is to take place.  Such notice shall also set forth such facts with
respect thereto as shall be reasonably necessary to indicate the effect of
such action (to the extent such effect may be known at the date of such
notice) on the Conversion Price and the number, kind or class of shares
which shall be deliverable upon conversion of Debentures.  In the case of
any action which would require the fixing of a record date, such notice
shall be given at least 15 days prior to the taking of such action. 
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

     Section 8.08.  Costs.  The Corporation shall pay all documentary,
stamp, transfer or other transactional taxes attributable to the issuance
or delivery of shares of Common Stock upon conversion of any Debentures;
provided that the Corporation shall not be required to pay any taxes which
may be payable in respect of any transfer involved in the issuance or
delivery of any certificate for such shares in a name other than that of
the holder of the Debentures, in respect of which shares are being issued.

                            TRANSFER OF DEBENTURE

     Section 10.01.  Restriction on Transfer.  In addition to any other
restrictions on transfer of the Debenture imposed by this Article X, the
Holder may transfer or assign his, her, or its rights and obligations under
this Agreement only in conjunction with the transfer or assignment of the
Debenture.

     Section 10.02.  Requirements of Transfer.  No transfer of the
Debenture shall be valid and effective unless and until (a) the transferor

                                                                      B-23

executes a written assignment of the Debenture or executes a separate power
of attorney indicating his intent to transfer ownership, (b) the transferee
executes a Debenture Agreement, which shall be identical to this Agreement
except for the Holder's name and the date of execution, and (c) the
transferor delivers written transfer instructions (i) signed by the
transferor and the transferee, (ii) stating the name and mailing and
residence address of the transferee, and (iii) stating the desired
effective date of such change of ownership.  If the transferee fails to
execute a Debenture Agreement, the transferee's signature on the
instructions of transfer will be deemed to constitute the transferee's
assent to the terms of the Debenture and the Debenture Agreement.

     Section 10.03.  Registration of Transfer.  Transfer of the Debenture
shall be registered upon the Company's register of Debentures following the
Company's receipt of all documents necessary to effect transfer in
accordance with Section 10.02.  Such documents may be either personally
delivered by the transferor or transferee or mailed to the Company in
accordance with Section 15.01 hereof.

     Section 10.04.  Effective Date of Transfer.  The effective date of the
transfer recorded on the Company's register of Debentures shall be the date
requested in the instructions of transfer; the effective date shall not,
however, precede the date of the most recent payment date of interest with
respect to such Debenture.  In the event such date precedes the date of the
most recent payment of interest on the Debenture or if the desired date is
omitted from the instructions of transfer, the Company may in its
discretion honor the transfer, and, in such case, the effective date of
transfer shall be the first date at which the Company is in receipt of all
of the items required by Section 10.02 hereof.

     Section 10.05.  Transferee as Holder.  Upon completion of a transfer
in accordance with the provisions provided in this Article X, such
Transferee shall be considered the Holder as if the transferee had been the
original party to execute this Agreement.

     Section 10.06.  Issuance of New Certificates.  Upon a transfer in
accordance with this Article X, and upon delivery by the transferor of his,

                                                                      B-24

her, or its Debenture certificate representing the Debenture being
transferred, the Company shall cancel such Debenture certificate and shall
issue a new certificate in the transferee's name.  Such new certificate
shall be issued in accordance with Article II hereof, and its provisions
will be identical to those of the old Debenture certificate except as to
the Holder's name and the date of execution, which date on the new
certificate shall be the same as the effective transfer date in accordance
with Section 10.04 hereof.

     Section 10.07.  Legend on Debenture.  The Debenture shall bear the
following legend:

     "THIS Debenture HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED (THE "ACT") OR THE SECURITIES LAWS OF ANY STATE,
     AND HAS BEEN ISSUED PURSUANT TO EXEMPTIONS FROM SUCH REGISTRATION
     AND QUALIFICATION REQUIREMENTS.  THIS Debenture MAY NOT BE SOLD,
     TRANSFERRED, OR ASSIGNED WITHOUT THE PERMISSION OF THE ISSUER AND
     UNLESS THIS Debenture SHALL HAVE BEEN DULY REGISTERED UNDER THE ACT
     AND REGISTERED OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS,
     OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER,
     REGISTRATION AND QUALIFICATION OF THE Debenture SHALL NOT BE
     REQUIRED.  THIS DEBENTURE IS SUBJECT TO AND ITS TRANSFER IS
     RESTRICTED BY THE TERMS AND PROVISIONS OF THAT CERTAIN DEBENTURE
     AGREEMENT, DATED ______________, EXECUTED BY AND BETWEEN THE
     COMPANY AND THE HOLDER OF THIS DEBENTURE, A COPY OF WHICH IS ON
     FILE IN THE OFFICES OF THE COMPANY."


                                 ARTICLE XI

                             REGISTRATION RIGHTS

     Section 11.01.  Registration on Request.  Upon the written request of
any holder or holders of at least 25% in the aggregate principal amount of
the Debentures and/or shares of Common Stock ("Shares") issued upon 
conversion of such Debentures, which request shall state the intended
method of disposition by such bolder or holders and shall request that the

                                                                      B-25

Company effect the registration of all or part of such Shares, or the
Shares issuable upon the conversion of such Debentures, or both, under the
Securities Act of 1933, as amended (the "Act"), the Company will promptly
give written notice of such requested registration to all holders of
outstanding Debentures and Shares, and thereupon will use its best efforts
to effect the registration under the Act of:

     (a)  the Shares which the Company has been so requested to register,
     for disposition in accordance with the intended method of disposition
     stated in such request, and

     (b)  all other outstanding Shares, or Shares issuable upon the
     conversion of Debentures, the holders of which shall have made written
     request (stating the intended method of disposition of such securities
     by such holders) to the Company for registration thereof within thirty
     (30) days after the receipt of such written notice from the Company,

all to the extent requisite to permit the disposition (in accordance with
the intended methods thereof as aforesaid) by the holders of the Shares so
registered and to maintain such registration in effect for a period of
twenty-four (24) months from the closing of the private placement under the
Private Placement Memorandum; provided, that the Company shall not be
required to register or use its best efforts to effect any registration of
Shares under the Act pursuant to this Section 11.01 more than once. 

     The Company shall have no obligation to register or use its best
efforts to effect any registration of Shares under the Act pursuant to this
Article XI which would be in conflict with the obligations of any holder or
holders of Debentures and/or Shares under any confidentiality agreement
between such holder or holders and the Company entered into in connection
with the offering of the Debentures to such holder or holders.

     Section 11.02.  Incidental Registration.  If the Company at any time
proposes to register any of its securities under the Act (otherwise than
pursuant to Section 11.01 and other than a registration on Form S-8, or the
form, if any, which supplants such Form), it will each such time give
written notice to all holders of outstanding Debentures and Shares of its

                                                                      B-26

intention to do so and, upon the written request of any such holder made
within thirty (30) days after the receipt of any such notice (which request
shall specify the Shares intended to be disposed of by such holder and
state the intended method of disposition thereof), the Company will use its
best efforts to cause all such outstanding Shares, or Shares issuable upon
the conversion of Debentures, the holders of which shall have so requested
the registration thereof, to be registered under the Act to the extent
requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Shares so registered; provided that,
if in the good faith judgment of the managing underwriter or underwriters
of a then proposed public offering of the Company's securities, such
registration of such Shares would materially and adversely affect such
public offering, then in such event the number of Shares and other
securities to be registered by the Company shall each be proportionally
reduced to such number as shall be acceptable to the managing underwriter.

     Section 11.03.  Registration Procedures.  If and whenever the Company
is required to use its best efforts to effect or cause the registration of
any Shares under the Act as provided in this Article XI, the Company will,
as expeditiously as possible:

     (a)  prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement with respect to such Shares and
     use its best efforts to cause such registration statement to become
     effective;

     (b)  prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for such period not exceeding twenty-four (24)
     months from the closing of the private placement under the Private
     Placement Memorandum as may be necessary to comply with the provisions
     of the Act with respect to the disposition of all Shares covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the seller or sellers thereof set
     forth in such registration statement;


                                                                      B-27

     (c)  furnish to each seller of such Shares such number of copies of
     such registration statement and of each such amendment and supplement
     thereto (in each case including all exhibits), such number of copies
     of the prospectus included in such registration statement (including
     each preliminary prospectus and, if any seller shall so request, a
     summary prospectus), in conformity with the requirements of the Act,
     and such other documents, as such seller may reasonably request in
     order to facilitate the disposition of the Shares owned by such
     seller;

     (d)  use its best efforts to register or qualify such Shares covered
     by such registration statement under such other securities or blue sky
     laws of such jurisdictions as each seller shall reasonably request,
     and do any and all other acts and things which may be reasonably
     necessary or advisable to enable such seller to consummate the
     disposition in such jurisdictions of the Shares owned by such seller;
     and

     (e)  notify each seller of any such Shares covered by such
     registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act within the period mentioned
     in subdivision (b) of this Section 11.03, of the happening of any
     event as a result of which the prospectus included in such
     registration statement, as then in effect, includes an untrue
     statement of a material fact or omits to state any material fact
     required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then
     existing, and at the request of any such seller prepare and furnish to
     such seller a reasonable number of copies of a supplement to or an
     amendment of such prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such Shares, such prospectus
     shall not include an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing.

     Section 11.04.  Registration Expenses.  All expenses incident to the

                                                                      B-28

Company's performance of or compliance with this Article XI, including,
without limitation, all registration and filing fees, fees and expenses of

     Section 11.05.  Indemnification.  

     (a)  In the event of any registration of any Restricted Shares under
     the Act pursuant to this Article XI, the Company will, to the extent
     permitted by law, indemnify and hold harmless the seller of such
     Shares and each underwriter of such securities and each other person,
     if any, who controls such seller or underwriter within the meaning of
     the Act, against any losses, claims, damages, or liabilities, joint or
     several, to which such seller or underwriter or controlling person may
     become subject, under the Act or otherwise, insofar as such losses,
     claims, damages, or liabilities (or actions in respect thereof) arise
     out of or are based upon (i) any untrue statement or alleged untrue
     statement of any material fact contained, on the effective date
     thereof, in any registration statement under which such securities
     were registered under the Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto,
     or (ii) any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and the Company will reimburse such seller and
     each such underwriter and each such controlling person for any legal
     or any other expenses reasonably incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability, or
     action, provided that the Company shall not be liable in any such case
     to the extent that any such loss, claim, damage, or liability arises
     out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in such registration
     statement, any such preliminary prospectus, final prospectus,
     amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company through an instrument
     duly executed by such seller or underwriter specifically for use in

                                                                      B-29

     the preparation thereof.

     (b)  The Company may require, as a condition to including any Shares
     in any registration statement filed pursuant to Section 11.03, that
     the Company shall have received an undertaking satisfactory to it from
     the prospective seller of such Shares and from each underwriter of
     such  Shares, to indemnify and hold harmless (in the same manner and
     to the same extent as set forth in subdivision (a) of this Section
     11.03) the Company, each director of the Company, each officer of the
     Company who shall sign such registration statement and any person who
     controls the Company within the meaning of the Act, with respect to
     any statement or omission from such registration statement, any
     preliminary prospectus or final prospectus contained therein, or any
     amendment or supplement thereto, if such statement or omission was
     made in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such
     seller or underwriter specifically for use in the preparation of such
     registration statement, preliminary prospectus, final prospectus,
     amendment, or supplement. 

     (c)  Promptly after receipt by an indemnified party of notice of the
     commencement of any action involving a claim referred to in the
     preceding subdivisions of this Section 11.05, such indemnified party
     will, if a claim in respect thereof is to be made against an
     indemnifying party, give written notice to the latter of the
     commencement of such action, provided that the failure of any
     indemnified party to give notice as provided therein shall not relieve
     the indemnifying party of its obligations under the preceding
     subdivisions of this Section 11.05.  In case any such action is
     brought against an indemnified party, the indemnifying party will be
     entitled to participate in and to assume the defense thereof, jointly
     with any other indemnifying party similarly notified to the extent
     that it may wish, with counsel reasonably satisfactory to such
     indemnified party, and after notice from the indemnifying party to
     such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified
     party for any legal or other expenses subsequently incurred by the

                                                                      B-30

     latter in connection with the defense thereof.  No indemnifying party,
     in the defense of any such claim or litigation, shall, except with the
     consent of each indemnified party, consent to entry of any judgment or
     enter into any settlement which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in respect to such
     claim or litigation.

             IMMUNITIES OF STOCKHOLDERS, OFFICERS, AND DIRECTORS

     No recourse shall be had for the payment of the principal of the
accompanying Debenture or of the interest thereon, or for any claim based
thereon or otherwise in respect thereof, or arising from this Agreement,
against any past, present, or future stockholder, director, or officer of
the Company, as such, whether by virtue of any constitution, statute, or

liability being by the acceptance of the accompanying Debenture and as part
of the consideration of the issuance thereof expressly waived and released
by the Holder and by any subsequent owners of the Debenture.


                                 ARTICLE XIV

                                 AMENDMENTS

     Section 14.01.  Without Consent of Holder.  The Company may amend this
Agreement and the Debenture without the consent of the Holder:

          (a)  To cure any ambiguity, defect, or inconsistency;

                                                                      B-32

          (b)  To comply with any consolidation or merger of the Company
               with or into any other corporation, or to comply with any
               conveyance of the business, assets, and properties of the
               Company as a whole or substantially as a whole, to any other
               corporation or other entity, provided that the corporation
               complies with the terms of Article XII hereof; and

          (c)  To make any change that does not adversely affect the rights
               of the Holder.

     Section 14.02.  With Consent of Holder.  Subject to the terms of
Section 14.01, the Company may amend this Agreement or the Debentures with
respect to any matter with the written consent of the holders of at least
66 2/3 percent (66 2/3%) of the aggregate principal amount of the
outstanding Debentures.  However, without consent of each holder affected,
an amendment under this section may not:

          (a)  Reduce the rate of or change the time for payment of
               interest on any Debenture;

          (b)  Reduce the principal of or change the fixed maturity of any
               Debenture;

          (c)  Make any Debenture convertible into any securities other
               than as described in Section 8.01; or

          (d)  Make any change in this Section 14.02.

     Section 14.03.  Revocation and Effect of Consents.  Until an amendment
or waiver becomes effective, a consent to such amendment or waiver by a
holder of a Debenture is a continuing consent by such holder and every
subsequent holder of such Debenture, even if notation of the consent is not
made on any Debenture.  Any such holder or subsequent holder may, however,
revoke the consent as to his Debenture if the Company receives the notice
of revocation before the date the amendment or waiver becomes effective. 
An amendment or waiver becomes effective in accordance with its terms and
thereafter binds every holder of a Debenture.

                                                                      B-33

     Section 14.04.  Notation on or Exchange of Debentures.  The Company
may place an appropriate notation concerning an amendment or waiver on any
Debenture thereafter issued.  The Company in exchange for all outstanding
certificates may issue new certificates that reflect the amendment or
waiver.

Item 26.  Recent Sales of Unregistered Securities

     In September, 1995, the Company closed a private placement in which
the Company offered solely to "accredited investors" a minimum of 400,000
Units and a maximum of 1,000,000 Units for $1.00 per unit.  Each Unit
comprised one share of the Company's Common Stock and one Warrant to
purchase one share of the Company's Common Stock for a period of 3 years at
$1.50 per share for the first 18 months and at $2.00 per share thereafter. 
In this private placement, the Company sold 742,300 Units for a total
consideration of $742,300.  The Units were offered for sale by Janney
Montgomery Scott, Inc. as placement agent on behalf of the Company.  The
placement agent received a commission equal to 6% of the gross proceeds of
the sale of the Units or $44,538.  

     In July, 1996, the Company closed a private placement of a minimum of
960,000 shares and a maximum of 1,160,000 shares of Series C 8% Convertible
Exchangeable Preferred Stock for $5.00 per share.  In the offering, the
total offering price was a minimum of $4,800,000 and a maximum of

the Securities Act of 1933.  The Preferred Stock was offered for sale by
Janney Montgomery Scott Inc. as placement agent on behalf of the Company. 
The placement agent received a commission equal to 7% of the gross proceeds

certificate representing the Debenture is destroyed, misplaced, or stolen,

discretion, the Company may, as a condition precedent to reissuing a new
Debenture certificate, require the Holder to do one or more of the
following things:

     (a)  Deliver a notice to the Company in the form prescribed by the

                                                                  Page 85

     (d)  Execute and file any form required by any state or federal
regulatory authority in connection with the loss of the Debenture
certificate.

After the Holder has complied with such requirements as the Company deems
necessary and appropriate, the Company shall cancel the lost certificate in
its register and shall issue a new Debenture certificate to the Holder with
terms and provisions identical to those contained in the lost certificate.

     Section 2.07.  Governmental Charges.  For any transfer of a Debenture
or exchange of a Debenture for Debentures of another denomination, the
Company may require from the Holder the payment of a sum sufficient to
reimburse it for any stamp tax or other governmental charge incidental
thereto.

                                SUBORDINATION

     Section 7.01.  Debentures Subordinated to Superior Indebtedness.
Anything in this Agreement or the Debentures to the contrary
notwithstanding, the indebtedness evidenced by the Debentures (such
indebtedness being hereinafter referred to as Subordinated Indebtedness)
shall be subordinate and junior in right of payment, to the extent and in
the manner hereinafter set forth, to (but only to) all Superior
Indebtedness (as defined herein) of the Company. 

     Section 7.02.  Payments on Subordinated Indebtedness.

     principal or interest on any Superior Indebtedness, no payment of
     principal, premium or interest shall be made on the Subordinated

     telegram has been given to the Company by the holder or holders of
     such Superior Indebtedness; provided that judicial proceedings by the
     holders of such Superior Indebtedness shall be commenced with respect

                                                                  Page 91

     (including all principal, premium, if any, and interest, including
     interest accruing after the commencement of any such proceeding)
     before any payment or distribution of any character, whether in cash,
     securities, or other property (other than securities of the Company or
     any other corporation provided for by a plan of reorganization or
     readjustment or similar plan, the payment of which is subordinated, at
     least to the extend provided in this Article VII with respect to

     thereof under any such plan) which would otherwise (but for the terms
     hereof) be payable or deliverable in respect of any Subordinated

                                                                  Page 92
     Indebtedness, shall be paid or delivered directly to the holders of
     the Superior Indebtedness, until all Superior Indebtedness shall have

     time outstanding irrevocably authorize, empower, and direct all
     receivers, trustees, liquidators, conservators, fiscal agents, and
     others having authority in the premises to effect all such payments
     and deliveries;

               (iii) each holder of the Subordinated Indebtedness at the
     time outstanding irrevocably authorizes and empowers each holder of
     the Superior Indebtedness or such holder's representative to demand,
     sue for, collect, and receive such holder's ratable share of all such
     payments and distributions and to receipt therefor, and to file and
     prove all claims therefor and take all such other action, in the name  
     of such holder or otherwise, as such holder of the Superior
     Indebtedness or such holder's representative may determine to be
     necessary or appropriate for the enforcement of this Section 7.03; and

               (iv) the holders of the Subordinated Indebtedness shall
     execute and deliver to each holder of the Superior Indebtedness or
     such holder's representative all such further instruments confirming
     the above authorization, and all such powers of attorney, proofs of
     claim, assignments of claim, and other instruments, and shall take all
     such other action as may be requested by such holder of the Superior
     Indebtedness or such holder's representative to enforce all claims
      upon or in respect of the Subordinated Indebtedness.

For all purposes of this Agreement, Superior Indebtedness shall not be
deemed to have been paid in full unless the holders thereof shall have
received cash equal to the amount of principal, premium, if any, and
interest in respect of all Superior Indebtedness at the time outstanding,
and in case there are two or more holders of the Superior Indebtedness any
payment or distribution required to be paid or delivered to the holders of
the Superior Indebtedness shall be paid or delivered to such holders
ratably according to the respective aggregate amounts remaining unpaid on
the Superior Indebtedness of such holders.


                                                                  Page 93

     Section 7.04.  Payments and Distributions Received.  If any payment or
distribution of any character (whether in cash, securities, or other
property) or any security shall be received by any holder of any of the
Subordinated Indebtedness in contravention of any of the terms of this
Article VII, and except as permitted by Section 7.03 or Section 7.06, such
payment or distribution or security shall be held in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of
the Superior Indebtedness for application to the payment of all Superior
Indebtedness remaining unpaid, to the extent necessary to pay all such
Superior Indebtedness in full.  In the event of the failure of any holder
of any of the Subordinated Indebtedness to endorse or assign any such
payment, distribution or security, any holder of the Superior Indebtedness
or such holder's representative is hereby irrevocably authorized to endorse
or assign the same. 

     Section 7.05.  Subrogation.  In case cash, securities, or other
property otherwise payable and deliverable to the holders of the
Subordinated Indebtedness shall have been applied pursuant to Section 7.03
or Section 7.04 to the payment of Superior Indebtedness in full, then and
in each such case, the holders of the Subordinated Indebtedness shall be
subrogated to any rights of any holders of Superior Indebtedness to receive
further payments or distributions in respect of or applicable to the
Superior Indebtedness.

     Section 7.06.  Acceleration of Subordinated Indebtedness.  In case any
Subordinated Indebtedness is declared due and payable because of the
occurrence of a default or event of default under circumstances when the
terms of Section 7.03 are not applicable, the holders of such Subordinated
Indebtedness shall not be entitled to receive payment or distribution in
respect thereof until all Superior Indebtedness at the time outstanding
shall have been paid in full; provided, however, that the holders of the
Subordinated Indebtedness shall continue to be entitled to receive (i)
current interest payments, (ii) regularly scheduled prepayments pursuant to
Section 3.01, and (iii) payments due at the stated maturity,
notwithstanding such declaration.


                                                                  Page 94

     Section 7.07.  Notice.  In the event that any Subordinated
Indebtedness shall become due and payable before its expressed maturity on
demand of the holder thereof as the result of the occurrence of a default
or event of default, the Company will give prompt notice in writing of such
happening to each holder of Superior Indebtedness.

     Section 7.08.  Subordination Not Affected, etc.  The terms of this
Article VII, the subordination effected hereby, and the rights of the
holders of the Superior Indebtedness shall not be affected by (a) any
amendment of or addition or supplement to any Superior Indebtedness or any
instrument or agreement relating thereto, (b) any exercise or non-exercise
of any right, power, or remedy under or in respect of any Superior
Indebtedness or any instrument or agreement relating thereto, or (c) any
waiver, consent, release, indulgence, extension, renewal, modification,
delay, or other action, inaction or omission, in respect of any Superior
Indebtedness or any instrument or agreement relating thereto or any
security therefor or guaranty thereof, whether or not any holder of any
Subordinated Indebtedness shall have had notice or knowledge of any of the
foregoing.

     Section 7.09.  Obligations Unimpaired.  No present or future holder of
Superior Indebtedness shall be prejudiced in the right to enforce
subordination of the Subordinated Indebtedness by any act or failure to act
on the part of the Company.  The provisions of this Article VII are solely
for the purpose of defining the relative rights of the holders of Superior
Indebtedness on the one hand and the holders of Subordinated Indebtedness
on the other hand, and nothing in this Article VII shall (a) impair as
between the Company and the holder of any Subordinated Indebtedness the
obligation of the Company, which is unconditional and absolute, to pay to
the holder thereof the principal, premium, if any, and interest thereon in
accordance with the terms thereof, or (b) prevent the holder of any
Subordinated Indebtedness from exercising all remedies otherwise permitted
by applicable law under this Agreement, subject to the rights, if any,
under this Article VII of the holders of Superior Indebtedness.


                                                                  Page 95


                                ARTICLE VIII

                          CONVERSION OF DEBENTURES

     Section 8.01.  Conversion Privilege.  The unpaid principal amount of
any Debenture or any portion thereof may, at the election of the holder
thereof, at any time after the date of such Debenture be converted into
shares of Common Stock at the conversion price per share of (a) prior to
the close of business on July 1, 1998, the conversion price per share of
Common Stock of Seventy-Five Cents ($0.75), (b) after July 1, 1998 and
prior to the close of business on July 1, 1999, the conversion price per
share of Common Stock of One Dollar and Twenty-Five Cents ($1.25), and (c)
thereafter, the conversion price per share of Common Stock of Two Dollars
($2.00), as such conversion price may be adjusted and readjusted from time
to time in accordance with Section 8.05 hereof (such conversion price, as
so adjusted and readjusted and in effect at any time, being herein called
the Conversion Price), into the number of fully paid and non-assessable
shares of Common Stock determined by dividing (x) the aggregate principal
amount of the Debentures to be so converted by (y) the Conversion Price in
effect at the time of such conversion.

     Section 8.02.  Manner of Conversion; Partial Conversion, etc.  
          
     (a) Any Debenture may be converted in whole or in part by the holder
     thereof by surrender of such Debenture, accompanied by a written
     statement designating the principal amount of such Debenture to be
     converted and stating the name and address of the person in whose name
     certificates for shares of Common Stock are to be registered, at the
     office of the Company specified in or pursuant to Section 15.01.  Upon
     any such partial conversion of a Debenture, the Company at its expense
     will forthwith issue and deliver to or upon the order of the holder
     thereof a new Debenture or Debentures in principal amount equal to the
     unpaid and unconverted principal amount of such surrendered Debenture,
     such new Debenture or Debentures to be dated and to bear interest from
     the date to which interest has been paid on such surrendered
     Debenture.  Each conversion shall be deemed to have been effected as
     of the close of business on the date on which such Debenture shall

                                                                  Page 96
     have been so surrendered to such office, and at such time the rights
     of the holder of such Debenture as such shall, to the extent of the
     principal amount thereof converted, cease, and the person or persons
     in whose name or names any certificate or certificates for shares of
     Common Stock shall be issuable upon such conversion shall be deemed to
     have become the holder or holders of record thereof.

     (b)  The Company shall pay all interest on any Debenture or portion of
     any Debenture surrendered for conversion to the date of such
     conversion.

     Section 8.03.  Delivery of Stock Certificates.  As promptly as
practicable after the conversion of any Debenture in full or in part, and
in any event within 20 days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will issue and
deliver to the holder of such Debenture, or as such holder (upon payment by
such holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of full and fractional shares of Common Stock
issuable upon such conversion.

     Section 8.04.  Shares to be Fully Paid; Reservation of Shares. The
Company covenants and agrees that all shares of Common Stock which may be
issued upon conversion of the Debentures will, upon issuance, be fully paid
and non-assessable and free from all taxes, liens, and charges with respect
to the issue thereof; and without limiting the generality of the foregoing,
the Company covenants and agrees that it will from time to time take all
such action as may be requisite to assure that the par value (if any) per
share of the Common Stock is at all times equal to or less than the then
effective purchase price per share of the Common Stock issuable upon
conversion of the Debentures.  The Company further covenants and agrees
that the Company will at all times have authorized, and reserved for the
purpose of issue or transfer upon the conversion of the Debentures, a
sufficient number of shares of its Common Stock to provide for the
conversion of the Debentures.

     Section 8.05.   Conversion Ratio Adjustments.  The Conversion Ratio
shall be subject to adjustment from time to time as follows:

                                                                  Page 97
          (a)  Stock Dividends, Subdivisions, Reclassifications or
          Combinations.  If the Corporation shall (i) declare a dividend or
          make a distribution on its Common Stock in shares of its Common
          Stock, (ii) subdivide or reclassify the outstanding shares of
          Common Stock into a greater number of shares, or (iii) combine or
          reclassify the outstanding Common Stock into a smaller number of
          shares, the Conversion Price in effect at the time of the record
          date for such dividend or distribution or the effective date of
          such subdivision, combination or reclassification shall be
          proportionately adjusted so that the holder of any Debentures
          surrendered for conversion after such date shall be entitled to
          receive the number of shares of Common Stock which he would have
          owned or been entitled to receive had such Debentures been
          converted immediately prior to such date.  Successive adjustments
          in the Conversion Ratio shall be made whenever any event
          specified above shall occur.

          (b)  Other Distributions.  In case the Corporation shall fix a
          record date for the making of a distribution to all holders of
          shares of its Common Stock (i) of shares of any class other than
          its Common Stock or (ii) of evidences of indebtedness of the
          Corporation or any Subsidiary or (iii) of assets (excluding cash
          dividends or distributions, and dividends or distributions
          referred to in subparagraph 8.05(a) above), or (iv) of rights or
          warrants, in each such case the Conversion Price in effect
          immediately prior thereto shall be immediately thereafter
          proportionately adjusted for such distribution so that the holder
          of Debentures would be entitled to receive the fair market value
          (as determined by the Board of Directors, whose determination
          shall be conclusive) of what he would have been entitled to
          receive had such Debentures been converted prior to such
          distribution.  Such adjustment shall be made successively
          whenever such a record date is fixed.  In the event that such
          distribution is not so made, the Conversion Price then in effect
          shall be readjusted, effective as of the date when the Board of
          Directors determines not to distribute such shares, evidences of
          indebtedness, assets, rights or warrants, as the case may be, to

                                                                  Page 98

          the Conversion Price which would then be in effect if such record
          date had not been fixed.

          (c)  Consolidation, Merger, Sale, Lease or Conveyance.  In case
          of any consolidation with or merger of the Corporation with or
          into another corporation, or in case of any sale, lease or
          conveyance to another corporation of the assets of the
          Corporation as an entirety or substantially as an entirety, the
          Debentures shall after the date of such consolidation, merger,
          sale, lease or conveyance be convertible into the number of
          shares of stock or other securities or property (including cash)
          to which the shares of Common Stock issuable (at the time of such
          consolidation, merger, sale, lease or conveyance) upon conversion
          of such Debenture would have been entitled to upon such
          consolidation, merger, sale, lease or conveyance; and in any such
          case, if necessary, the provisions set forth herein with respect
          to the rights and interests thereafter of the holders of the
          Debentures shall be appropriately adjusted so as to be
          applicable, as nearly as may reasonably be, to any shares of
          stock or other securities or property thereafter deliverable on
          conversion of the Debentures.

     Section 8.06.  Statement Regarding Adjustments.  Whenever the
Conversion Price shall be adjusted as provided in Section 8.05, the
Corporation shall forthwith file, at the principal office of the
Corporation, a statement showing in detail the facts requiring such
adjustment and the Conversion Price that shall be in effect after such
adjustment, and the Corporation shall also cause a copy of such statement
to be sent by mail, first class postage prepaid, to each holder of
Debentures, at its address appearing on the Corporation's records.  Where
appropriate, such copy may be given in advance and may be included as part
of a notice required to be mailed under the provisions of Section 8.07.

     Section 8.07.  Notice to Holders.  In the event the Corporation shall
propose to take any action of the type described in Section 8.05, the
Corporation shall give notice to each holder of Debentures, in the manner
set forth in Section 8.06, which notice shall specify the record date, if

                                                                  Page 99
any, with respect to any such action and the approximate date on which such
action is to take place.  Such notice shall also set forth such facts with
respect thereto as shall be reasonably necessary to indicate the effect of
such action (to the extent such effect may be known at the date of such
notice) on the Conversion Price and the number, kind or class of shares
which shall be deliverable upon conversion of Debentures.  In the case of
any action which would require the fixing of a record date, such notice
shall be given at least 15 days prior to the taking of such action. 
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

     Section 8.08.  Costs.  The Corporation shall pay all documentary,
stamp, transfer or other transactional taxes attributable to the issuance
or delivery of shares of Common Stock upon conversion of any Debentures;
provided that the Corporation shall not be required to pay any taxes which
may be payable in respect of any transfer involved in the issuance or
delivery of any certificate for such shares in a name other than that of
the holder of the Debentures, in respect of which shares are being issued.

                                 ARTICLE X  

                            TRANSFER OF DEBENTURE

     Section 10.01.  Restriction on Transfer.  In addition to any other
restrictions on transfer of the Debenture imposed by this Article X, the
Holder may transfer or assign his, her, or its rights and obligations under
this Agreement only in conjunction with the transfer or assignment of the
Debenture.

     Section 10.02.  Requirements of Transfer.  No transfer of the
Debenture shall be valid and effective unless and until (a) the transferor
executes a written assignment of the Debenture or executes a separate power
of attorney indicating his intent to transfer ownership, (b) the transferee

                                                                  Page 102
executes a Debenture Agreement, which shall be identical to this Agreement
except for the Holder's name and the date of execution, and (c) the
transferor delivers written transfer instructions (i) signed by the
transferor and the transferee, (ii) stating the name and mailing and
residence address of the transferee, and (iii) stating the desired
effective date of such change of ownership.  If the transferee fails to
execute a Debenture Agreement, the transferee's signature on the
instructions of transfer will be deemed to constitute the transferee's
assent to the terms of the Debenture and the Debenture Agreement.

     Section 10.03.  Registration of Transfer.  Transfer of the Debenture
shall be registered upon the Company's register of Debentures following the
Company's receipt of all documents necessary to effect transfer in
accordance with Section 10.02.  Such documents may be either personally
delivered by the transferor or transferee or mailed to the Company in
accordance with Section 15.01 hereof.

     Section 10.04.  Effective Date of Transfer.  The effective date of the
transfer recorded on the Company's register of Debentures shall be the date
requested in the instructions of transfer; the effective date shall not,
however, precede the date of the most recent payment date of interest with
respect to such Debenture.  In the event such date precedes the date of the
most recent payment of interest on the Debenture or if the desired date is
omitted from the instructions of transfer, the Company may in its
discretion honor the transfer, and, in such case, the effective date of
transfer shall be the first date at which the Company is in receipt of all
of the items required by Section 10.02 hereof.

     Section 10.05.  Transferee as Holder.  Upon completion of a transfer
in accordance with the provisions provided in this Article X, such
Transferee shall be considered the Holder as if the transferee had been the
original party to execute this Agreement.

     Section 10.06.  Issuance of New Certificates.  Upon a transfer in
accordance with this Article X, and upon delivery by the transferor of his,
her, or its Debenture certificate representing the Debenture being
transferred, the Company shall cancel such Debenture certificate and shall

                                                                  Page 103
issue a new certificate in the transferee's name.  Such new certificate
shall be issued in accordance with Article II hereof, and its provisions
will be identical to those of the old Debenture certificate except as to
the Holder's name and the date of execution, which date on the new
certificate shall be the same as the effective transfer date in accordance
with Section 10.04 hereof.

     Section 10.07.  Legend on Debenture.  The Debenture shall bear the
following legend:

     "THIS Debenture HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED (THE "ACT") OR THE SECURITIES LAWS OF ANY STATE,
     AND HAS BEEN ISSUED PURSUANT TO EXEMPTIONS FROM SUCH REGISTRATION
     AND QUALIFICATION REQUIREMENTS.  THIS Debenture MAY NOT BE SOLD,
     TRANSFERRED, OR ASSIGNED WITHOUT THE PERMISSION OF THE ISSUER AND
     UNLESS THIS Debenture SHALL HAVE BEEN DULY REGISTERED UNDER THE ACT
     AND REGISTERED OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS,
     OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER,
     REGISTRATION AND QUALIFICATION OF THE Debenture SHALL NOT BE
     REQUIRED.  THIS DEBENTURE IS SUBJECT TO AND ITS TRANSFER IS
     RESTRICTED BY THE TERMS AND PROVISIONS OF THAT CERTAIN DEBENTURE
     AGREEMENT, DATED ______________, EXECUTED BY AND BETWEEN THE
     COMPANY AND THE HOLDER OF THIS DEBENTURE, A COPY OF WHICH IS ON
     FILE IN THE OFFICES OF THE COMPANY."

                                 ARTICLE XI

                             REGISTRATION RIGHTS

     Section 11.01.  Registration on Request.  Upon the written request of
any holder or holders of at least 25% in the aggregate principal amount of
the Debentures and/or shares of Common Stock ("Shares") issued upon 
conversion of such Debentures, which request shall state the intended
method of disposition by such bolder or holders and shall request that the
Company effect the registration of all or part of such Shares, or the
Shares issuable upon the conversion of such Debentures, or both, under the
Securities Act of 1933, as amended (the "Act"), the Company will promptly

                                                                  Page 104
give written notice of such requested registration to all holders of
outstanding Debentures and Shares, and thereupon will use its best efforts
to effect the registration under the Act of:

     (a)  the Shares which the Company has been so requested to register,
     for disposition in accordance with the intended method of disposition
     stated in such request, and

     (b)  all other outstanding Shares, or Shares issuable upon the
     conversion of Debentures, the holders of which shall have made written
     request (stating the intended method of disposition of such securities
     by such holders) to the Company for registration thereof within thirty
     (30) days after the receipt of such written notice from the Company,

all to the extent requisite to permit the disposition (in accordance with
the intended methods thereof as aforesaid) by the holders of the Shares so
registered and to maintain such registration in effect for a period of
twenty-four (24) months from the closing of the private placement under the
Private Placement Memorandum; provided, that the Company shall not be
required to register or use its best efforts to effect any registration of
Shares under the Act pursuant to this Section 11.01 more than once. 

     The Company shall have no obligation to register or use its best
efforts to effect any registration of Shares under the Act pursuant to this
Article XI which would be in conflict with the obligations of any holder or
holders of Debentures and/or Shares under any confidentiality agreement
between such holder or holders and the Company entered into in connection
with the offering of the Debentures to such holder or holders.

     Section 11.02.  Incidental Registration.  If the Company at any time
proposes to register any of its securities under the Act (otherwise than
pursuant to Section 11.01 and other than a registration on Form S-8, or the
form, if any, which supplants such Form), it will each such time give
written notice to all holders of outstanding Debentures and Shares of its
intention to do so and, upon the written request of any such holder made
within thirty (30) days after the receipt of any such notice (which request
shall specify the Shares intended to be disposed of by such holder and

                                                                  Page 105
state the intended method of disposition thereof), the Company will use its
best efforts to cause all such outstanding Shares, or Shares issuable upon
the conversion of Debentures, the holders of which shall have so requested
the registration thereof, to be registered under the Act to the extent
requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Shares so registered; provided that,
if in the good faith judgment of the managing underwriter or underwriters
of a then proposed public offering of the Company's securities, such
registration of such Shares would materially and adversely affect such
public offering, then in such event the number of Shares and other
securities to be registered by the Company shall each be proportionally
reduced to such number as shall be acceptable to the managing underwriter.

     Section 11.03.  Registration Procedures.  If and whenever the Company
is required to use its best efforts to effect or cause the registration of
any Shares under the Act as provided in this Article XI, the Company will,
as expeditiously as possible:

     (a)  prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement with respect to such Shares and
     use its best efforts to cause such registration statement to become
     effective;

     (b)  prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for such period not exceeding twenty-four (24)
     months from the closing of the private placement under the Private
     Placement Memorandum as may be necessary to comply with the provisions
     of the Act with respect to the disposition of all Shares covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the seller or sellers thereof set
     forth in such registration statement;

     (c)  furnish to each seller of such Shares such number of copies of
     such registration statement and of each such amendment and supplement
     thereto (in each case including all exhibits), such number of copies

                                                                  Page 106

     of the prospectus included in such registration statement (including
     each preliminary prospectus and, if any seller shall so request, a
     summary prospectus), in conformity with the requirements of the Act,
     and such other documents, as such seller may reasonably request in
     order to facilitate the disposition of the Shares owned by such
     seller;

     (d)  use its best efforts to register or qualify such Shares covered
     by such registration statement under such other securities or blue sky
     laws of such jurisdictions as each seller shall reasonably request,
     and do any and all other acts and things which may be reasonably
     necessary or advisable to enable such seller to consummate the
     disposition in such jurisdictions of the Shares owned by such seller;
     and

     (e)  notify each seller of any such Shares covered by such
     registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act within the period mentioned
     in subdivision (b) of this Section 11.03, of the happening of any
     event as a result of which the prospectus included in such
     registration statement, as then in effect, includes an untrue
     statement of a material fact or omits to state any material fact
     required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then
     existing, and at the request of any such seller prepare and furnish to
     such seller a reasonable number of copies of a supplement to or an
     amendment of such prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such Shares, such prospectus
     shall not include an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing.

     Section 11.04.  Registration Expenses.  All expenses incident to the
Company's performance of or compliance with this Article XI, including,
without limitation, all registration and filing fees, fees and expenses of
complying with securities or blue sky laws, printing expenses and fees and

                                                                  Page 107
disbursements of counsel for the Company and of independent pubic
accountants, but excluding underwriting commissions and discounts, shall be
borne by the Company.  

     Section 11.05.  Indemnification.  

     (a)  In the event of any registration of any Restricted Shares under
     the Act pursuant to this Article XI, the Company will, to the extent
     permitted by law, indemnify and hold harmless the seller of such
     Shares and each underwriter of such securities and each other person,
     if any, who controls such seller or underwriter within the meaning of
     the Act, against any losses, claims, damages, or liabilities, joint or
     several, to which such seller or underwriter or controlling person may
     become subject, under the Act or otherwise, insofar as such losses,
     claims, damages, or liabilities (or actions in respect thereof) arise
     out of or are based upon (i) any untrue statement or alleged untrue
     statement of any material fact contained, on the effective date
     thereof, in any registration statement under which such securities
     were registered under the Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto,
     or (ii) any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and the Company will reimburse such seller and
     each such underwriter and each such controlling person for any legal
     or any other expenses reasonably incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability, or
     action, provided that the Company shall not be liable in any such case
     to the extent that any such loss, claim, damage, or liability arises
     out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in such registration
     statement, any such preliminary prospectus, final prospectus,
     amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company through an instrument
     duly executed by such seller or underwriter specifically for use in
     the preparation thereof.

     (b)  The Company may require, as a condition to including any Shares

                                                                  Page 108

     in any registration statement filed pursuant to Section 11.03, that
     the Company shall have received an undertaking satisfactory to it from
     the prospective seller of such Shares and from each underwriter of
     such  Shares, to indemnify and hold harmless (in the same manner and
     to the same extent as set forth in subdivision (a) of this Section
     11.03) the Company, each director of the Company, each officer of the
     Company who shall sign such registration statement and any person who
     controls the Company within the meaning of the Act, with respect to
     any statement or omission from such registration statement, any
     preliminary prospectus or final prospectus contained therein, or any
     amendment or supplement thereto, if such statement or omission was
     made in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such
     seller or underwriter specifically for use in the preparation of such
     registration statement, preliminary prospectus, final prospectus,
     amendment, or supplement. 

     (c)  Promptly after receipt by an indemnified party of notice of the
     commencement of any action involving a claim referred to in the
     preceding subdivisions of this Section 11.05, such indemnified party
     will, if a claim in respect thereof is to be made against an
     indemnifying party, give written notice to the latter of the
     commencement of such action, provided that the failure of any
     indemnified party to give notice as provided therein shall not relieve
     the indemnifying party of its obligations under the preceding
     subdivisions of this Section 11.05.  In case any such action is
     brought against an indemnified party, the indemnifying party will be
     entitled to participate in and to assume the defense thereof, jointly
     with any other indemnifying party similarly notified to the extent
     that it may wish, with counsel reasonably satisfactory to such
     indemnified party, and after notice from the indemnifying party to
     such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified
     party for any legal or other expenses subsequently incurred by the
     latter in connection with the defense thereof.  No indemnifying party,
     in the defense of any such claim or litigation, shall, except with the
     consent of each indemnified party, consent to entry of any judgment or

                                                                  Page 109

     enter into any settlement which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in respect to such
     claim or litigation.

against any past, present, or future stockholder, director, or officer of
the Company, as such, whether by virtue of any constitution, statute, or

                                 AMENDMENTS

     Section 14.01.  Without Consent of Holder.  The Company may amend this
Agreement and the Debenture without the consent of the Holder:

          (a)  To cure any ambiguity, defect, or inconsistency;

          (b)  To comply with any consolidation or merger of the Company

                                                                  Page 111

               with or into any other corporation, or to comply with any
               conveyance of the business, assets, and properties of the
               Company as a whole or substantially as a whole, to any other
               corporation or other entity, provided that the corporation
               complies with the terms of Article XII hereof; and

          (c)  To make any change that does not adversely affect the rights
               of the Holder.

     Section 14.02.  With Consent of Holder.  Subject to the terms of
Section 14.01, the Company may amend this Agreement or the Debentures with
respect to any matter with the written consent of the holders of at least
66 2/3 percent (66 2/3%) of the aggregate principal amount of the
outstanding Debentures.  However, without consent of each holder affected,
an amendment under this section may not:

          (a)  Reduce the rate of or change the time for payment of
               interest on any Debenture;

          (b)  Reduce the principal of or change the fixed maturity of any
               Debenture;

          (c)  Make any Debenture convertible into any securities other

          (d)  Make any change in this Section 14.02.

     Section 14.03.  Revocation and Effect of Consents.  Until an amendment
or waiver becomes effective, a consent to such amendment or waiver by a
holder of a Debenture is a continuing consent by such holder and every
subsequent holder of such Debenture, even if notation of the consent is not
made on any Debenture.  Any such holder or subsequent holder may, however,
revoke the consent as to his Debenture if the Company receives the notice
of revocation before the date the amendment or waiver becomes effective. 
An amendment or waiver becomes effective in accordance with its terms and
thereafter binds every holder of a Debenture.

                                                                  Page 112

     Section 14.04.  Notation on or Exchange of Debentures.  The Company
may place an appropriate notation concerning an amendment or waiver on any
Debenture thereafter issued.  The Company in exchange for all outstanding
certificates may issue new certificates that reflect the amendment or
waiver.

                  Warrant Agreement and Warrant Certificate

                            TGC INDUSTRIES, INC.
                              WARRANT AGREEMENT
                                 (Warrants)


     THIS AGREEMENT, dated as of July 28, 1995 (the "Agreement"), is
entered into between TGC INDUSTRIES, INC., a Texas corporation (the

                                                                  Page 118

"Company"), and AMERICAN STOCK TRANSFER & TRUST COMPANY of New York, New
York ("Warrant Agent").


                             W I T N E S E T H:

     WHEREAS, Company at or about the same time that it is entering into
this Agreement, is issuing Warrants (the "Warrants") to purchase up to
approximately 1,000,000 shares of the Company's Common Stock, each Warrant
representing the right to purchase from the Company one (1) share of Common
Stock of the Company at the purchase price ("Purchase Price") of $1.50 per
share for a period of eighteen (18) months and of $2.00 per share
thereafter until the Warrant expires on a date which is three (3) years
from the date of issuance, unless extended, subject to the terms and
conditions hereinafter set forth; and

     WHEREAS, Company desires to appoint Warrant Agent to act on behalf of
Company, and Warrant Agent is willing so to act in connection with the
issuance, transfer, exchange, and replacement of the certificates
evidencing the Warrants (the "Warrant Certificates") and the exercise of
the Warrants, and to act as depository for the Warrants. 

     NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

     Section 1.     Appointment of Warrant Agent.  Company hereby appoints
American Stock Transfer & Trust Company to act as agent for Company in
accordance with the terms and conditions hereinafter in this Agreement set
forth, and American Stock Transfer & Trust Company hereby accepts such
appointment.  Company may from time to time appoint such Co-Warrant Agents
as it may deem necessary or desirable.

     Section 2.     Form of Warrant Certificates.  The Warrant Certificates
(and the forms of election to purchase shares and of assignment to be
printed on the reverse thereof) shall be substantially of the tenor and
purport recited in Exhibit A hereto and may have such letters, numbers, or
other marks of identification or designation and such legends, summaries,

                                                                  Page 119
or endorsements printed, lithographed, or engraved thereon as Company may
deem appropriate and as are not inconsistent with the provisions of this
Warrant Agreement, or as may be required to comply with any law or with any
rule or regulation made pursuant thereto or with any rule or regulation of
any stock exchange.  The Warrant Certificates may bear such notice of
restriction on transfer and/or exercise as Company's counsel may deem
necessary or appropriate for Company to comply with federal or state laws
or regulations, including securities laws.  Subject to the provisions of
Section "5" hereof, the Warrant Certificates shall be dated as of the date
of issuance thereof by Warrant Agent, either upon initial issuance or upon
transfer or exchange, and on their face shall entitle the holders thereof
to purchase a whole share, subject to Sections "6" below, at the price per
share set forth therein ("Purchase Price"), except that the Purchase Price
per share shall be subject to adjustments as provided herein.

     Section 3.     Countersignature and Registration.  The Warrant
Certificates shall be executed on behalf of Company by its Chairman of the
Board, its President, or any Vice President, by facsimile signature, and
have affixed thereto a facsimile of Company's seal which shall be attested
by the Secretary or an Assistant Secretary of Company by facsimile
signature.  The Warrant Certificates shall be manually counter-signed by
Warrant Agent and shall not be valid for any purpose unless so
counter-signed.  In case any officer of Company who has signed any of the
Warrant Certificates ceases to be such Officer of Company before
countersignature by the Warrant Agent and issuance and delivery by Company,
such Warrant Certificates, nevertheless, may be counter-signed by Warrant
Agent, issued, and delivered with the same force and effect as though the
person who signed such Warrant Certificates had not ceased to be such
officer of Company.

     Warrant Agent shall keep, or cause to be kept, at its principal
office, books for registration and transfer of the Warrant Certificates
issued hereunder.  Such books shall show the names and addresses of the
respective holders of the Warrant Certificates, the number of Warrants
evidenced on its face by each of the Warrant Certificates, and the date of
each of the Warrant Certificates.


                                                                  Page 120

     Section 4.     Transfer, Split-Up, Combination, and Exchange of
Warrant Certificates; Mutilated, Destroyed, Lost, or Stolen Warrant
Certificates.

          A.   Subject to the provisions of Section "11" to follow, any
Warrant Certificate, with or without other Warrant Certificates, may be
transferred, split up, combined, or exchanged for another Warrant
Certificate or Warrant Certificates, entitling the registered holder to
purchase a like number of shares as the Warrant Certificate or Warrant
Certificates surrendered then entitled such holder to purchase.  Any
registered holder desiring to transfer, split up, combine, or exchange any
Warrant Certificates shall make such request in writing delivered to
Warrant Agent, and shall surrender the Warrant Certificate or Warrant
Certificates to be transferred, split up, combined, or exchanged at the
principal office of Warrant Agent.  Thereupon Warrant Agent shall
countersign and deliver to the person entitled thereto a Warrant
Certificate, or Warrant Certificates, as the case may be, as so requested. 
Company may require payment of a sum sufficient to cover all taxes and
other governmental charges that may be imposed in connection with any
transfer, split up, combination, or exchange of Warrant Certificates.

          B.   Upon receipt by Company and Warrant Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction, or
mutilation of a Warrant Certificate, and, in case of loss, theft,
destruction, or mutilation, of indemnity or security reasonably
satisfactory to them, and reimbursement to Company and Warrant Agent of all
reasonable expenses incidental thereto, and upon surrender to Warrant Agent
and cancellation of the Warrant Certificate, if mutilated, Warrant Agent
shall countersign and deliver to the registered owner a new Warrant
Certificate in lieu of, and evidencing the right to purchase the same
number of shares as, the Warrant Certificate so lost, stolen, destroyed, or
mutilated.

     Section 5.     Subsequent Issue of Warrant Certificates.  Subsequent
to their original issuance, no Warrant Certificates may be issued except
(A) Warrant Certificates issued upon any transfer, combination, split up,
or exchange of Warrants pursuant to Section "4" hereof, (B) Warrant

                                                                  Page 121
Certificates issued in replacement of mutilated, destroyed, lost, or stolen
Warrant Certificates pursuant to Section "4" hereof, (C) Warrant
Certificates issued pursuant to Section "6" hereof upon the partial
exercise of any Warrant Certificate to evidence the unexercised portion of
the Warrants evidenced by such Warrant Certificate, and (D) Warrant
Certificates issued pursuant to Section "10.G" hereof.

     Section 6.     Exercise of Warrants; Purchase Price; Expiration of
Warrants.

          A.   Subject to Section "6.E" below, the registered holder of any
Warrant Certificate may exercise it in whole or in part at any time, but
only in such multiples as are required to permit the issuance by Company of
one or more shares, by surrender of the Warrant Certificate with the form
of election to purchase on the reverse side thereof duly executed, to
Warrant Agent at the principal office of Warrant Agent in the New York, New
York, at or prior to 5:00 P.M. (New York, New York time) on July 31, 1998,
or such later date or dates as Company may determine (July 31, 1998, or the
later date or dates being the "Expiration Date"), together with payment of
the Purchase Price, payable to Company, for each share into which the
Warrants are exercised.

          B.   Subject to Section "20.B" below, the exercise of a Warrant
by a registered holder will entitle such holder to purchase one (1) share
for the Purchase Price of $1.50 per share if exercised at or prior to
January 31, 1997 (approximately eighteen months from the date hereof), and
for the Purchase Price of $2.00 per share if exercised at or prior to the
Expiration Date; provided such price shall be subject to adjustment as
provided in Section "10" hereof and shall be payable in lawful money of the
United States of America.

          C.   Upon receipt of a Warrant Certificate, with the form of
election to purchase duly executed, accompanied by payment of the Purchase
Price for its shares to be purchased and an amount equal to any applicable
transfer tax in cash, or by certified check, bank draft, or postal or
express money order payable to the order of Company, Warrant Agent shall
thereupon promptly: (1) requisition from any transfer agent of the shares,

                                                                  Page 122
certificates for the number of whole shares to be purchased, and Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests; and (2) promptly after receipt of such certificates cause the
same to be delivered to or upon the order of the registered holder of such
Warrant Certificate registered in such name or names as may be designated
by such holder. 

          D.   In case the registered holder of any Warrant Certificate
exercises less than all the Warrants evidenced thereby, a new Warrant
Certificate evidencing Warrants equivalent to the Warrants remaining
unexercised shall be issued by Warrant Agent to the registered holder of
such Warrant Certificate or to such holder's duly authorized assigns,
subject to the provisions of Section "11" hereof.

          E.   No Warrant is exercisable by a holder unless, at the time of
an exercise by such holder, (1) there is either (a) a registration
statement or prospectus covering the shares that is effective under (i) the
Securities Act of 1933, as amended, and (ii) the securities laws of the
state of the address of record of such holder, or (b) an exemption
available from registration for the Warrant exercise and issuance of the
shares in the opinion of counsel to Company; and (2) such exercise and
issuance would otherwise be in compliance with applicable law in the
opinion of counsel to Company.  No Warrant may be, directly or indirectly,
transferred to, or exercised by, any person in any state where such
transfer or exercise would violate any law, including securities law, of
such state in the opinion of counsel to Company.

          F.   To the extent that any Warrant Certificates remain
outstanding at 5:01 P.M. on the Expiration Date, such outstanding Warrant
Certificates shall be automatically deemed exercised on behalf of each
record holder of Warrant Certificates into shares of the Company's Common
Stock at the rate ("Conversion Rate") of one-tenth (1/10) of a share of
Common Stock for each Warrant Certificate or Certificates representing,
immediately before the Expiration Date, the right to purchase one (1) share
of Common Stock.  Upon surrender thereafter of such Warrant Certificate or
Certificates, the Company shall issue and cause to be delivered to the
registered holder of such Warrant Certificate or Certificates in the

                                                                  Page 123
holder's name or upon the written order of such holder in such name or
names as such registered holder may designate, a certificate for the number
of shares of Common Stock into which the Warrants represented by such
Warrant Certificate or Certificates have been thus automatically exercised. 
Such certificates shall be deemed to have been issued and any person so
designated to be named therein shall be deemed to have become a holder of
record of such share or shares of Common Stock as of the Expiration Date;
provided, however, that if, on the Expiration Date, the transfer books for
the Common Stock shall be closed, the certificate for such share or shares
of Common Stock shall be issuable as of the date on which such books shall
next be opened and until such date the Company shall be under no duty to
deliver any certificate for such share or shares.  The Conversion Rate
shall not be subject to adjustment upon any adjustment of the number of
shares or Purchase Price of Common Stock issuable upon the exercise of each
Warrant under the provisions of Section 6 hereof.

     Section 7.     Cancellation and Destruction of Warrant Certificates.

     All Warrant Certificates surrendered for the purpose of exercise,
exchange, substitution, or transfer shall, if surrendered to Company or to
any of its agents, be delivered to Warrant Agent for cancellation or in
canceled form, or if surrendered to Warrant Agent shall be canceled by it,
and no Warrant Certificates may be issued in lieu thereof except as
expressly permitted by any of the provisions of this Warrant Agreement. 
Company shall deliver to Warrant Agent for cancellation and retirement, and
Warrant Agent shall so cancel and retire, any other Warrant Certificate
purchased or acquired by Company otherwise than upon the exercise thereof. 
Warrant Agent may deliver all canceled Warrant Certificates to Company, or
shall, at the written request of Company, destroy the canceled Warrant
Certificates, in which case Warrant Agent shall deliver a certificate of
destruction thereof to Company.

     Section 8.     Reservation and Availability of Shares of Common Stock.

     Company hereby covenants and agrees with respect to reservation and
availability of shares of its Common Stock and related matters as follows:

                                                                  Page 124

          A.   Company covenants and agrees that it will cause to be
reserved and kept available, out of its authorized and unissued shares of
Common Stock, the number of shares of Common Stock which will be sufficient
to permit the exercise in full of all outstanding Warrants.

          B.   At any time when the shares of Common Stock, issuable upon
the exercise of Warrants, may be listed on any national securities
exchange, Company shall cause all shares reserved for such issuance to be
authorized for listing on such exchange upon official notice of issuance
upon such exercise.

          C.   Company covenants and agrees that it shall take all such
actions as may be necessary to insure that all shares of Common Stock
delivered upon exercise of Warrants shall, at the time of delivery of the
certificates for such shares (subject to payment of the Purchase Price), be
duly and validly authorized and issued and fully paid, nonassessable
shares.

          D.   Company further covenants and agrees that it will pay when
due and payable any and all federal and state taxes (excluding income
taxes) and charges which may be payable in respect of the issuance or
delivery of the Warrant Certificates or of any shares of Common Stock upon
the exercise of Warrants. Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the
transfer or delivery of Warrant Certificates, or the issuance or delivery
of certificates for shares of Common Stock in a name other than that of the
registered holder of the Warrant Certificate evidencing Warrants
surrendered for exercise, or to issue or deliver any certificates for
shares of Common Stock upon the exercise of any Warrants, until any such
tax has been paid (any such tax being payable by the holder of such Warrant
Certificate at the time of surrender) or until it has been established to
Company's satisfaction that no such tax is due.

     Section 9.     Common Stock Record Date.

     Each person in whose name any certificate for shares of Common Stock
of the Company is issued upon the exercise of Warrants shall for all

                                                                  Page 125
purposes be deemed to have become the holder of record of the shares of
Common Stock represented thereby on, and such certificate shall be dated,
the date upon which the Warrant Certificate evidencing such Warrants was
duly surrendered and payment of the Purchase Price (and any applicable
transfer taxes) was made; provided, however, that if the date of such
surrender and payment is a date upon which the transfer books of Company
are closed, such person shall be deemed to have become the record holder of
such shares on, and such certificate shall be dated, the next succeeding
business day on which the transfer books of Company are open.  Prior to the
exercise of the Warrants evidenced thereby, the holder of a Warrant
Certificate shall not be entitled to any rights of a shareholder of Company
with respect to shares for which the Warrants are exercisable, including,
without limitation, the right to vote, to receive dividends or other
distributions, or to exercise any preemptive rights, and shall not be
entitled to receive any notice of any proceedings of Company, except as
provided herein.

     Section 10.    Effect of Certain Events.

     The Purchase Price, the number of shares of Common Stock of the
Company covered by each Warrant, and the number of Warrants outstanding are
subject to adjustment from time to time upon the occurrence of the events
enumerated in this Section "10."  

          A.   Adjustment for Issuances or Sales Below Purchase Price. If
and whenever the Company shall issue or sell any shares of its Common Stock
for a consideration per share less than the Purchase Price in effect
immediately prior to the time of such issue or sale, then, forthwith upon
such issue or sale, the Purchase Price shall be reduced to a price
(calculated to the nearest one hundredth of a cent) determined by dividing
(1) an amount equal to the sum of (a) the number of shares of Common Stock
outstanding immediately prior to such issue or sale multiplied by the then
existing Purchase Price, and (b) the consideration, if any, received by the
Company upon such issue or sale, by (2) the total number of shares of
Common Stock outstanding immediately after such issue or sale.

          B.   For purposes of Subsection A. above, the following clauses

                                                                  Page 126
 (1) to (9), inclusive, shall also be applicable:

               (1)  Issuance of Rights or Options. In case at any time the
Company shall grant (whether directly or by assumption in a merger or
otherwise) any rights to subscribe for or to purchase, or any options for
the purchase of, Common Stock or any stock or securities convertible into
or exchangeable for Common Stock (such convertible or exchangeable stock or
securities being herein called Convertible Securities) whether or not such
rights or options or the right to convert or exchange any such Convertible
Securities are immediately exercisable, and the price per share for which
Common Stock is issuable upon the exercise of such rights or options or
upon conversion or exchange of such Convertible Securities (determined by
dividing (a) the total amount, if any, received or receivable by the
Company as consideration for the granting of such rights or options, plus
the minimum aggregate amount of additional consideration payable to the
Company upon the exercise of such rights or options, plus, in the case of
such rights or options which relate to Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the
issue or sale of such Convertible Securities and upon the conversion or
exchange thereof, by (b) the total maximum number of shares of Common Stock
issuable upon the exercise of such rights or options or upon the conversion
or exchange of all such Convertible Securities issuable upon the exercise
of such rights or options) shall be less than the Purchase Price in effect
immediately prior to the time of the granting of such rights or options,
then the total maximum number of shares of Common Stock issuable upon the
exercise of such rights or options or upon conversion or exchange of the
total maximum amount of such Convertible Securities issuable upon the
exercise of such rights or options shall (as of the date of granting of
such rights or options) be deemed to be outstanding and to have been issued
for such price per share. Except as provided in clause (3) below, no
further adjustments of the Purchase Price shall be made upon the actual
issue of such Common Stock or of such Convertible Securities upon exercise
of such rights or options or upon the actual issue of such Common Stock or
of such Convertible Securities upon exercise of such rights or options or
upon the issue of such Common Stock upon conversion or exchange of such
Convertible Securities.

                                                                  Page 127

               (2)  Issuance of Convertible Securities. In case the Company
shall issue (whether directly or by assumption in a merger or otherwise) or
sell any Convertible Securities, whether or not the rights to exchange or
convert thereunder are immediately exercisable, and the price per share for
which Common Stock is issuable upon such conversion or exchange (determined
by dividing (a) the total amount received or receivable by the corporation
as consideration for the issue or sale of such Convertible Securities, plus
the minimum aggregate amount of additional consideration, if any, payable
to the corporation upon the conversion or exchange thereof, by (b) the
total maximum number of shares of Common Stock issuable upon the conversion
or exchange of all such Convertible Securities) shall be less than the
Purchase Price in effect immediately prior to the time of such issue or
sale, then the total maximum number of shares of Common Stock issuable upon
conversion or exchange of all such Convertible Securities shall (as of the
date of the issue or sale of such Convertible Securities) be deemed to be
outstanding and to have been issued for such price per share, provided that
(i) except as provided in clause (3) below, no further adjustments of the
Purchase Price shall be made upon the actual issue of such Common Stock
upon conversion or exchange of such Convertible Securities, and (ii) if any
such issue or sale of such Convertible Securities is made upon exercise of
any rights to subscribe for or to purchase or any option to purchase any
such Convertible Securities for which adjustments of the Purchase Price
have been or are to be made pursuant to other provisions of this Subsection
B., no further adjustment of the Purchase Price shall be made by reason of
such issue or sale.

               (3)  Change in Option Price or Conversion Rate. Upon the
happening of any of the following events, namely, if the purchase price
provided in any rights or options referred to in clause (1) of this
Subsection B., the additional consideration, if any, payable upon the
conversion or exchange of Convertible Securities referred to in clause (1)
or clause (2) of this Subsection B., or the rate at which any Convertible
Securities referred to in clause (1) or clause (2) of this Subsection (B)
are convertible into or exchangeable for Common Stock shall change (other
than under or by reason of provisions designed to protect against
dilution), the Purchase Price in effect at the time of such event shall
forthwith be readjusted to the Purchase Price which would have been in

                                                                  Page 128
effect at such time had such rights, options or Convertible Securities
still outstanding provided for such changed purchase price, additional
consideration or conversion rate, as the case may be, at the time initially
granted, issued or sold; and on the expiration of any such option or right
or the termination of any such right to convert or exchange such
Convertible Securities, the Purchase Price then in effect hereunder shall
forthwith be increased to the Purchase Price which would have been in
effect at the time of such expiration or termination had such right, option
or Convertible Security, to the extent outstanding immediately prior to
such expiration or termination, never been issued, and the Common Stock
issuable thereunder shall no longer be deemed to be outstanding. If the
purchase price provided for in any such right or option referred to in
clause (1) of this Subsection B. or the rate at which any Convertible
Securities referred to in clause (1) or clause (2) of this Subsection B.
are convertible into or exchangeable into or exchangeable for Common Stock,
shall decrease at any time under or by reason of provisions with respect
thereto designed to protect against dilution, then in case of the delivery
of Common Stock upon the exercise of any such right or option or upon
conversion or exchange of any such Convertible Security, the Purchase Price
then in effect hereunder shall forthwith be adjusted to such respective
amount as would have obtained had such rights, option or Convertible
Security never been issued as to such Common Stock and had adjustments been
made upon the issuance of the shares of Common Stock delivered as
aforesaid, but only if as a result of such adjustment the Purchase Price
then in effect hereunder is thereby decreased.

               (4)  Stock Dividends. In case the Company shall declare a
dividend or make any other distributions upon any stock of the Company
payable in Common Stock or Convertible Securities, any Common Stock or
Convertible Securities, as the case may be, issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold 
without consideration.

               (5)  Consideration for Stock.  In case any shares of Common
Stock or Convertible Securities or any rights or options to purchase any
such Common Stock or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount

                                                                  Page 129
received by the Company therefor, without deduction therefrom of any
expenses incurred or any underwriting commissions or concessions paid or
allowed by the Company in connection therewith. In case any shares of
Common Stock or Convertible Securities or any rights or options to purchase
any such Common Stock or Convertible Securities shall be issued or sold for
a consideration other than cash, the amount of the consideration other than
cash received by the Company shall be deemed to be the fair value of such
consideration as determined in good faith by the Board of Directors of the
Company, without deduction of any expenses incurred or any underwriting
commissions or concessions paid or allowed by the Company in connection
therewith.  In case any shares of Common Stock or Convertible Securities or
any rights or options to purchase such Common Stock or Convertible
Securities shall be issued in connection with any merger or consolidation
in which the Company is the surviving corporation, the amount of
consideration therefor shall be deemed to be the fair value as determined
by the Board of Directors of the Company of such portion of the assets and
business of the non-surviving corporation or corporations as such Board
shall determine to be attributable to such Common Stock or Convertible
Securities, rights or options, as the case may be.

               (6)  Record Date. In case the Company shall take a record of
the holders of its Common Stock for the purpose of entitling them (a) to
receive a dividend or other distribution payable in Common Stock or in
Convertible Securities, or (b) to subscribe for or purchase Common Stock or
Convertible Securities, then such record date shall be deemed to be the
date of the issue or sale of the shares of Common Stock deemed to have been
issued upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

               (7)  Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock for the purposes of Subsection
B.

               (8)  Determination of Consideration in Connection with

                                                                  Page 130
 Certain Acquisitions. Anything in clause (5) of this Subsection B. to the
contrary notwithstanding, in the case of an acquisition where all or part
of the purchase price is payable in Common Stock or Convertible Securities
but is stated as a dollar amount, where the Company upon making the
acquisition pays only part of a maximum dollar purchase price which is
payable in Common Stock or Convertible Securities and where the balance of
such purchase price is deferred or is contingently payable under a formula
related to earnings over a period of time, (a) the consideration received
for any Common Stock or Convertible Securities delivered at the time of the
acquisition shall be deemed to be such part of the total consideration as
the portion of the dollar purchase price then paid in Common Stock or
Convertible Securities bears to the total maximum dollar purchase price
then paid in Common Stock or Convertible Securities, and (b) in connection
with each issuance of additional Common Stock or Convertible Securities
pursuant to the terms of the agreement relating to such acquisition, the
consideration received shall be deemed to be such part of the total
consideration as the portion of the dollar purchase price then and
theretofore paid in Common Stock or Convertible Securities bears to the
total maximum dollar purchase price payable in Common Stock or Convertible
Securities multiplied by a fraction, the numerator of which shall be the
number of shares (or in the case of Convertible Securities other than
stock, the aggregate principal amount) then issued and the denominator of
which shall be the total number of shares (or in the case of Convertible
Securities other than stock, the aggregate principal amount) then and
theretofore issued under such acquisition agreement. If it is determined
that any part of the deferred or contingent portion of such purchase price
shall not be payable, the Purchase Price then in effect hereunder shall
forthwith be readjusted to such Purchase Price as would have obtained (i)
had the adjustment made in connection with such acquisition been made upon
the basis of the issuance of only the number of shares of Common Stock or
Convertible Securities actually issued in connection with such acquisition,
and (ii) had adjustments been made on the basis of the Purchase Price as
adjusted in clause (1) for all issued or sale (as prices which would have
affected such adjusted Purchase Price) of Common Stock or rights, options
or Convertible Securities made after such acquisition. In the event that
only a part of the purchase price for an acquisition is paid in Common
Stock or Convertible Securities in the manner referred to in this clause

                                                                  Page 131
(viii), the term "total consideration" as used in this clause (8) shall
mean that part of the aggregate consideration as is fairly allocable to the
purchase price paid in Common Stock or Convertible Securities in the manner
referred to in this clause (8), as determined by the Board of Directors of
the Company.

               (9)  Exempt Transactions. Notwithstanding anything to the
contrary in this Section 10, no adjustment in the Purchase Price shall
result, pursuant to Subsection A. above or otherwise, from the issuance by
the Company of shares of its Common Stock as a result of the following
transactions:

          (a)  The completion of the offering of which these Warrants are a
     part, namely the sale of up to 1,000,000 Units at $1.00 per Unit for a
     total of $1,000,000, pursuant to that certain Subscription Agreement
     dated June 30, 1995, each Unit consisting of one share of Common Stock
     and one Warrant with the rights set forth in this Agreement;

          (b)  The exercise of options heretofore or hereafter granted
     under the Company's 1986 Incentive Stock Option Plan, as the same
     may be amended, extended or substituted from time to time provided,
     that the number of shares available thereunder may not be increased
     by any such amendment, extension or substitution; and

          (c)  The exercise of options heretofore or hereafter granted
     under the Company's 1993 Stock Option Plan, as the same may be
     amended, extended or substituted from time to time provided, that
     the number of shares available thereunder may not be increased by
     any such amendment, extension or substitution.

          C.   Adjustment for Certain Special Dividends. In case the
Company shall declare a dividend upon the Common Stock payable otherwise
than out of consolidated earnings or consolidated earned surplus,
determined in accordance with generally accepted accounting principles,
including the making of appropriate deductions for minority interest, if
any, in subsidiary corporations, and otherwise than in Common Stock or
Convertible Securities, the Company shall give the holders of each Warrant

                                                                  Page 132
 thirty (30) days prior written notice of the date as of which the holders
of Common Stock of record entitled to such special dividend shall be
determined. For the purposes of the foregoing a dividend other than in cash
shall be considered payable out of earnings or surplus (other than
revaluation or paid-in surplus) only to the extent that such earnings or
surplus are charged an amount equal to the fair value of such dividend as
determined by the Board of Directors of the Company.

          D.   Subdivision or Combination of Stock. (1) In case the Company
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the Purchase Price in effect immediately prior to
such subdivision shall be proportionately reduced, and, conversely (2) in
case the outstanding shares of Common Stock of the Company shall be
combined into a smaller number of shares, the Purchase Price in effect
immediately prior to such combination shall be proportionately increased.

          E.   Reorganizations, Mergers and Sales of Assets.  In case of
any capital reorganization or any reclassification of the Common Stock of
the Company, the consolidation of Company with or the merger of Company
with or into any other corporation, or the sale of the properties and
assets of Company as, or substantially as, an entirety to any other
corporation, then each holder of a Warrant then outstanding shall be
entitled to purchase such number of shares of stock or other securities or
property of Company or any other corporation resulting from such
reorganization, reclassification, consolidation, merger, or sale, as was
exchanged for the number of shares of Common Stock of Company which the
holder would have been entitled to purchase except for such action.  The
subdivision or combination of shares of Common Stock at any time
outstanding into a greater or lesser number of shares of Common Stock shall
not be deemed to be a reclassification of the Common Stock of Company for
the purposes of this Subsection "E."

          F.   Adjustment of Number of Shares.  

               (1)  Except as provided in Subsection G, to follow, upon
each adjustment of the Purchase Price as a result of (a) an issuance or
sale of Common Stock below the Purchase Price as provided in Subsections A

                                                                  Page 133
and B above, including (without limitation) a dividend or distribution in
shares of capital stock, or (b) a subdivision of outstanding shares of
Common Stock as provided in Subsection "D.(1)" hereof, the number of shares
of Common Stock purchasable upon exercise of any Warrant Certificate shall
be increased to the number of shares of Common Stock (calculated to the
nearest hundredth) obtained by multiplying (i) the number of shares of
Common Stock purchasable immediately prior to such adjustment upon exercise
of Warrants (evidenced by the Warrant Certificate held by such holder) by
(ii) the Purchase Price in effect immediately prior to such adjustment, and
dividing the product so obtained by the Purchase Price in effect after such
adjustment.  

               (2)  Except as provided in Subsection "G" to follow, upon
each adjustment of the Purchase Price as a result of a combination of the
Common Stock as provided in Subsection "D.(2)" hereof, the number of shares
of Common Stock purchasable upon exercise of any Warrant Certificate shall
be decreased to the number of shares of Common Stock (calculated to the
nearest hundredth) obtained by multiplying (a) the number of shares of
Common Stock purchasable immediately prior to such adjustment upon exercise
of Warrants evidenced by the Warrant Certificate held by such holder, by
(b) the Purchase Price in effect immediately prior to such adjustment, and
then dividing the product so obtained by the Purchase Price in effect after
such adjustment.  

          G.   Adjustment of Number of Warrants.  In lieu of an adjustment
in the number of shares covered by a Warrant, Company may elect, on or
after the date of any adjustment of the Purchase Price, to adjust the
number of Warrants.

          H.   Warrant Certificates.  Irrespective of any adjustments or
change in the Purchase Price or the number of shares of the Common Stock
issuable upon the exercise of the Warrants, the Warrant Certificates
theretofore and thereafter issued may continue to express the Purchase
Price per share and the number of shares which were expressed upon the
Warrant Certificates when initially issued.

          I.   Par Value Considerations.  Before taking any action which

                                                                  Page 134
 would cause an adjustment reducing the Purchase Price below the then par
value, if any, of the shares of Common Stock issuable upon exercise of the
Warrants, Company shall take any corporate action which may, in the opinion
of its counsel, be necessary in order that Company may validly and legally
issue fully paid and nonassessable shares of such Common Stock at such
adjusted Purchase Price.

          J.   Notice of Adjustment.  Whenever the Purchase Price, the
number of shares of Common Stock issuable upon the exercise of each
Warrant, or the number of Warrants are adjusted as provided in this Section
"10," Company shall (1) promptly obtain a certificate of a firm of
independent public accountants of recognized standing selected by the Board
of Directors (who may be the regular auditors of Company) setting forth the
purchase Price as so adjusted, the number of shares of Common Stock
issuable upon the exercise of each Warrant as so adjusted, and a brief
statement of the facts accounting for such adjustment, (2) promptly file
with Warrant Agent and with each transfer agent for the Common Stock a copy
of such certificate, and (3) in the discretion of Company, mail a brief
summary thereof to each holder of a Warrant Certificate in accordance with
Section "20.B."

          K.   Action by the Board of Directors. If any event occurs as to
which in the opinion of the Board of Directors of the Company the other
provisions of this Section "10" are not strictly applicable or if strictly
applicable would not fairly protect the conversion rights of the holders of
the Warrants in accordance with the essential intent and principles of such
provisions, then the Board of Directors shall make an adjustment in the
application of such provisions, in accordance with such essential intent
and principles, so as to protect such exercise rights as aforesaid.

     Section 11.    Fractional Warrants, Fractional shares, and
Consideration Therefor.

          A.   Company shall not be required to issue fractions of Warrants
or to distribute Warrant Certificates which evidence fractional Warrants.

          B.   Upon exercise of the Warrants, the Company shall not be

                                                                  Page 135
required to issue fractional shares of its Class A Common Stock, or to
distribute certificates which evidence fractional shares. In lieu of the
issuance of any such fractional shares on the exercise of the Warrants,
Company shall pay cash to the registered holder of the Warrants based on
the difference between the market price of the shares of the Company which
underlie the Warrants, which price shall be computed as the per share
closing price (if such shares are listed on an exchange) or the average
between the per share bid and asked prices as of the close of business on
the exercise date as reported by the National Association of Securities
Dealers Automated Quotation System and the Purchase Price on the exercise
date times the fractional share which is represented by the Warrants on the
exercise date.  However, if no market price exists, then the amount of cash
to be paid to the registered holder of the Warrants in lieu of any
fractional securities of the Company shall be the product of the difference
between the per share Tangible Net Book Value (defined hereafter) of the
shares of Class A Common Stock outstanding on the last business day prior
to the exercise date and the Purchase Price on the exercise date, times the
fractional security which otherwise would have been issuable in the absence
of this Section.  For purposes of payment of cash in lieu of the issuance
of fractional securities, the term "Tangible Net Book Value" means the
consolidated total shareholders' equity of the Company, determined in
accordance with generally accepted accounting principles ("GAAP"), less the
aggregate net amount of the following items to the extent, if any, that
they were included in consolidated assets or deducted from consolidated
liabilities in computing shareholders' equity:  (1) all franchises,
licenses, patents, patent applications, copyrights, trade marks, trade
names, goodwill, experimental or organizational expense, unamortized debt
discount and expense, and all other assets which under GAAP are deemed
intangible; and (2) any write-up of assets after December 31, 1994.

          C.   The holder of a Warrant by the acceptance of the Warrant
expressly waives such holder's right to receive any fractional Warrant or
any fractional security of the Company upon exercise of a Warrant or on the
Expiration Date in the absence of the provisions of this Agreement.

     Section 12.    Right of Action.

                                                                  Page 136

     All rights of action in respect of this Agreement are vested in the
respective registered holders of the Warrant Certificates; and any
registered holder of any Warrant Certificate, without the consent of
Warrant Agent or of the holder of any other Warrant Certificate, may, in
such holder's own behalf and for such holder's own benefit, enforce, and
may institute and maintain any suit, action, or proceeding against Company
to enforce, or otherwise in respect of, such holder's right to exercise the
Warrants evidenced by such Warrant Certificate in the manner provided in
such Warrant Certificate and in this Agreement.

     Section 13.    Agreement of Warrant Certificate Holders.

     Every holder of a Warrant Certificate, by accepting same, consents and
agrees with Company, Warrant Agent, and with every other holder of a
Warrant Certificate that:

          A.   the Warrants are transferable only on the registry books of
Warrant Agent upon surrender of the Warrant Certificates at the principal
office of Warrant Agent and only as provided in Section "4"; and 

          B.   Company and Warrant Agent may deem and treat the person in
whose name the Warrant Certificate is registered as the absolute owner
thereof and of the Warrants evidenced thereby (notwithstanding any
notations of ownership or writing on the Warrant Certificates made by
anyone other than the Company or Warrant Agent) for all purposes
whatsoever, and neither Company nor Warrant Agent shall be affected by any
notice to the contrary.

     Section 14.  Concerning Warrant Agent.

     Company agrees to pay to Warrant Agent reasonable compensation for
services rendered by it hereunder and, from time to time, its disbursements
incurred in the administration and execution of this Agreement and the
exercise and performance of its duties hereunder.  Company also agrees to
indemnify Warrant Agent for, and to hold it harmless against, any loss,
liability, or expense, incurred by Warrant Agent, for anything done or
omitted by Warrant Agent, without negligence or misconduct on the part of

                                                                  Page 137
Warrant Agent, in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim
of liability in the premises.

     Section 15.  Merger or Consolidation or Change of Name of Warrant
Agent.

     Any corporation into which Warrant Agent or any successor Warrant
Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which Warrant
Agent or any successor Warrant Agent is a party, or any corporation
succeeding to the business of Warrant Agent or any successor Warrant Agent,
shall be the successor to the Warrant Agent under this Agreement without
the execution or filing of any paper or any further act on the part of any
of the parties hereto, provided that such corporation would be eligible for
appointment as a successor Warrant Agent under the provisions of Section
"17."  In case at the time such successor Warrant Agent succeeds to the
agency created by this Agreement, any of the Warrant Certificates have been
counter-signed but not delivered, any such successor Warrant Agent may
adopt the countersignature of the predecessor Warrant Agent and deliver
such Warrant Certificates so counter-signed; and in case at that time any
of the Warrant Certificates have not been counter-signed, any successor
Warrant Agent may countersign such Warrant Certificates either in the name
of the predecessor Warrant Agent or in the name of the successor Warrant
Agent; and in all such cases such Warrant Certificates shall have the full
force provided in the Warrant Certificates and in this Agreement.

     In case at any time the name of Warrant Agent is changed and at such
time any of the Warrant Certificates have been counter-signed but not
delivered, Warrant Agent may adopt the countersignature under its prior
name and deliver Warrant Certificates so counter-signed; and in case at
that time any of the Warrant Certificates have not been counter-signed,
Warrant Agent may countersign such Warrant Certificates either in its prior
name or in its changed name; and in all such cases such Warrant
Certificates shall have the full force provided in the Warrant Certificates
and in this Agreement.

                                                                  Page 138

     Section 16.  Duties of Warrant Agent.

     Warrant Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which Company
and the holders of Warrant Certificates, by their acceptance thereof, shall
be bound: 

          A.   Warrant Agent may consult with legal counsel for Company,
and the opinion of such counsel shall be full and complete authorization
and protection to Warrant Agent as to any action taken or omitted by it in
good faith and in accordance with such opinion.

          B.   Whenever in the performance of its duties under this
Agreement Warrant Agent deems it necessary or desirable that any fact or
matter be proved or established by Company prior to taking or suffering any
action hereunder, such fact or matter (unless other evidence in respect
thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by the Chairman of the
Board, the President, or a Vice President, and by the Treasurer, an
Assistant Treasurer, the Secretary, or an Assistant Secretary of Company,
and delivered to Warrant Agent; and such certificate shall be full
authorization to Warrant Agent for any action taken or suffered in good
faith by it under the provisions of this Agreement in reliance upon such
certificate.

          C.   Warrant Agent shall be liable hereunder only for its own
negligence or misconduct.

          D.   Warrant Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained in this Agreement or in the
Warrant Certificates (except its countersignature thereof) or be required
to verify the same, but all such statements and recitals are and shall be
deemed to have been made by Company only.

          E.   Warrant Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery
hereof (except the due execution hereof by Warrant Agent) or in respect of

                                                                  Page 139
the validity or execution of any Warrant Certificate (except its
countersignature thereof) or the genuineness of any endorsed document of
assignment or other document believed by it to be genuine; nor shall it be
responsible for any breach by Company of any covenant or condition
contained in this Agreement or in any Warrant Certificate; nor shall it be
responsible for the adjustment of the Purchase Price or the making of any
change in the number of shares of Common Stock required under the
provisions of Section "10" or responsible for the manner, method, or amount
of any such change or the ascertaining of the existence of facts that would
require any such adjustment or change (except with respect to the exercise
of Warrants evidenced by Warrant Certificates after actual notice of any
adjustment of the purchase Price); nor shall it by any act hereunder be
deemed to make any representation or warranty as to the authorization or
reservation of any securities to be issued pursuant to this Agreement or
any warrant Certificate or as to whether any securities will, when issued,
be validly authorized and issued, fully paid, and nonassessable.

          F.   Company agrees that it shall perform, execute, acknowledge,
and deliver or cause to be performed, executed, acknowledged, and delivered
all such further and other acts, instruments, and assurances as may
reasonably be required by Warrant Agent for the carrying out or performing
by Warrant Agent of the provisions of this Agreement.

          G.   Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the President, a Vice President, the Secretary,
an Assistant Secretary, the Treasurer, or an Assistant Treasurer of
Company, and to apply to such officers for advice or instructions in
connection with its duties, and it shall not be liable for any action taken
or suffered to be taken by it in good faith in accordance with instructions
received from any such officer.

     Section 17.    Change of Warrant Agents.

     Warrant Agent may resign and be discharged from its duties under this
Agreement upon thirty days' notice in writing mailed to Company by
registered or certified mail, and to the holders of the Warrants by

                                                                  Page 140
first-class mail.  Company may remove Warrant Agent or any successor
Warrant Agent upon thirty days' notice in writing, mailed to Warrant Agent
or a successor Warrant Agent, as the case may be, and to each transfer
agent of the Common Stock, by registered or certified mail, and to the
holders of the Warrants by first- class mail.  If the Warrant Agent
resigns, is removed, or becomes otherwise incapable of acting, Company
shall appoint a successor Warrant Agent.  If Company fails to make such
appointment within a period of thirty (30) days after such removal or after
it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Warrant Agent or by the holder of a Warrant (who
shall, with such notice, submit his, her, or its warrant Certificate for
inspection by Company), then the registered holder of any Warrant may apply
to any court of competent jurisdiction for the appointment of a new Warrant
Agent. Any successor Warrant Agent, whether appointed by Company or by such
a court, shall be a corporation organized and doing business, or a
partnership or association formed, under the laws of the United States or
of the State of New York, in good standing, having an office in New York
City, New York, which has at the time of its appointment as Warrant Agent a
combined capital and surplus of at least Ten Million Dollars ($10,000,000). 
After appointment, the successor Warrant Agent shall be vested with the
same powers, rights, duties, and responsibilities as if it had been
originally named as Warrant Agent without further act or deed; but the
predecessor Warrant Agent shall deliver and transfer to the successor
Warrant Agent any property at the time held by it hereunder, and execute
and deliver any further assurance, conveyance, act, or deed necessary for
the purpose.  Not later than the effective date of any such appointment,
Company shall file notice thereof in writing with the predecessor Warrant
Agent and each transfer agent of the Common Stock, and mail a notice
thereof in writing to the registered holders of the Warrants.  Failure to
give any notice provided for in this Section "17," however, or any defect
therein, shall not affect the legality or validity of the resignation or
removal of Warrant Agent or the appointment of the successor Warrant Agent,
as the case may be.

     Section 18.    Change of Expiration Date.

     If Company, from time to time, changes the Expiration Date to a later

                                                                  Page 141
date, as soon as practicable after Company determines to make the change,
and in any event at least thirty (30) days before the Expiration Date,
Company shall notify the holders of the Warrants of the change in writing
in the manner provided in Section "19."

     Section 19.    Notices.

          A.   Nothing contained in this Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the holders thereof the
right to vote or to consent to or receive notice as stockholders in respect
of the meetings of stockholders or the election of Directors of Company or
any other matter, or any rights whatsoever as stockholders of Company;
provided, however, that in the event that:

               (1)  Company takes action to make any distribution (other
than cash dividends payable out of available earned surplus, cash payments
of any dividend or distribution which was declared by the Board of
Directors prior to the date hereof, and dividends or distributions payable
in shares of Common Stock) to the holders of Common Stock;

               (2)  Company shall take action to offer for subscription
pro-rata to the holders of Common Stock any additional shares of stock of
any class or other rights or securities convertible into Common Stock;

               (3)  Company shall take action to accomplish any capital
reorganization, or reclassification of the capital stock of Company (other
than a subdivision or combination of the Common Stock), or consolidation or
merger of Company into or with, or sale of all or substantially all of its
assets to, another corporation; or

               (4)  Company takes action looking to voluntary or
involuntary dissolution, liquidation, or winding up of Company; 
then, in any one or more of such cases, Company shall (a) at least fifteen
(15) days prior to the date on which the books of Company close or a record
is taken for such distribution or subscription rights or for determining
rights to vote in respect of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation, or winding up, cause

                                                                  Page 142
written notice thereof to be sent by first-class mail, postage prepaid, to
Warrant Agent and each registered holder of a Warrant Certificate at such
holder's address appearing on the Warrant register, and (b) in the case of
any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation, or winding up, cause at least fifteen (15) days'
prior written notice of the date when the same shall take place to be given
to Warrant Agent.  Such notice in accordance with the foregoing clause
"(a)" shall also specify, in the case of any such distribution or
subscription rights, the date on which the holders of Common Stock will be
entitled thereto, and shall also specify the proposed date on which the
holders of Common Stock will be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding up, as the case may be.

          B.   Notices or demands authorized by this Agreement to be given
or made by Warrant Agent or by the holder of any Warrant Certificate to or
on Company shall be sufficiently given or made if sent by first-class mail,
postage prepaid, addressed (until another address is filed in writing by
Company with Warrant Agent) as follows:

          A.   Warrant Agent may, without the consent or concurrence of the
holders of the Warrants, by supplemental agreement or otherwise, join with
Company in making any changes to, or corrections in, this Agreement that

                  (unless extended by TGC Industries, Inc.)

                            TGC INDUSTRIES, INC.

                             Warrant Certificate

          THIS CERTIFIES THAT for value received
_________________________________________________________________, or
registered assigns, is the owner of the number of Warrants ("Warrants") of
TGC Industries, Inc. (the "Company") set forth above, each of which
entitles the owner hereof to purchase, subject to the restrictions
referenced herein, prior to the close of business on July 31, 1998, or such
later date or dates as Company may determine (the "Expiration Date"), at
the principal office of American Stock Transfer & Trust Company, or its
successor as Warrant Agent, in New York City, New York, one (1) share of
Common Stock of TGC Industries, Inc. (the "Shares"), at the purchase price,
subject to the Warrant Agreement (defined below), of $1.50 per whole share
if exercised before 5:00 p.m. (New York time), on January 31, 1997
(approximately eighteen months from the date hereof) or of $2.00 per whole
share if exercised before 5:00 p.m. (New York time), on the Expiration Date

                                                                  Page 152
upon presentation and surrender of this Warrant Certificate with the Form
of Election to Purchase duly executed.  The number of Warrants evidenced by
this Warrant Certificate (and the number of Shares which may be purchased
upon exercise thereof) set forth above is the number as of the date of this
Certificate, based on the shares of Common Stock of the Company as
constituted at such date.

          No Warrant is exercisable by a holder unless, at the time of an
exercise by such holder:  (1) there is either (a) a registration statement
or prospectus covering the Shares that is effective under the securities
Act of 1933, as amended, and the securities laws of the state of the
address of record of such holder, or (b) an exemption from registration is
available for the Warrant exercise and the issuance of the Shares in the
opinion of counsel to Company; and (2) such exercise and issuance would
otherwise be in compliance with applicable law in the opinion of counsel to
Company.                                _______________

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT ONLY AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE.  WITHOUT SUCH
REGISTRATION, SUCH SECURITIES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED AT
ANY TIME WHATSOEVER, EXCEPT UPON DELIVERY TO THE CORPORATION OF AN OPINION
OF COUNSEL SATISFACTORY TO THE CORPORATION THAT REGISTRATION IS NOT
REQUIRED FOR SUCH TRANSFER.

          This Certificate is subject to all of the terms, provisions, and
conditions of an agreement dated as of July 28, 1995 ("Warrant Agreement")
between Company and Warrant Agent, which Warrant Agreement is incorporated
herein by reference and made a part hereof and to which Warrant Agreement
reference is made for a full description of the rights, limitations of
rights, obligations, duties, and immunities of Warrant Agent, Company, and
the holders of the Warrants.  Copies of the Warrant Agreement are on file
at the principal office of the Warrant Agent in New York City, New York.

          As provided in the Warrant Agreement, the Purchase Price and the
number of Shares which may be purchased upon the exercise of the Warrants
evidenced by this Certificate are subject to modification and adjustment.

                                                                  Page 153

          This Certificate, with or without other Warrant Certificates,
upon surrender at the principal office of the Warrant Agent in New York
City, New York, may be exchanged for another Warrant Certificate or Warrant
Certificates of like tenor evidencing Warrants entitling the holder to
purchase a like aggregate number of Shares as the Warrants evidenced by the
Warrant Certificate or Warrant Certificates surrendered.  If only a part of
the Warrants evidenced by this Certificate are exercised, the holder hereof
shall be entitled to receive, upon surrender hereof, another Warrant
Certificate or Warrant Certificates for the number of whole Warrants not
exercised.

          No holder of the Warrants evidenced by this Certificate shall be
entitled to vote or receive dividends or be deemed the holder of Shares or
any other securities of Company which may at any time be issuable on the
exercise of these Warrants for any purpose, nor shall anything contained in
the Warrant Agreement or herein be construed to confer upon the holder of
these Warrants, as such, any of the rights of a shareholder of Company or
any right to vote for the election of directors or upon any matter
submitted to shareholders at any meeting thereof, or to give or withhold
consent to any corporate action (whether upon any recapitalization, issue
of stock, reclassification of stock, change of par value, consolidation,
merger, conveyance, or otherwise) or, except as provided in the Warrant
Agreement, to receive notice of meetings, or to receive dividends or
subscription rights or otherwise, until the Warrants evidenced by this
Warrant Certificate have been exercised and the Units purchasable upon the
exercise thereof has become deliverable as provided in the Warrant
Agreement.

          To the extent that any Warrant Certificates remain outstanding at
5:01 P.M. on the Expiration Date, such outstanding Warrant Certificates
shall be automatically deemed exercised on behalf of each record holder of
Warrant Certificates into shares of the Company's Common Stock at the rate
("Conversion Rate") of one-tenth (1/10) of a share of Common Stock for each
Warrant Certificate or Certificates representing, immediately before the
Expiration Date, the right to purchase one share of Common Stock.

          Upon the exercise of the Warrant, in lieu of the issuance of any

                                                                  Page 154

fractional Shares, the Company shall pay cash to the registered holder of
the Warrant based on the difference between the market price of the Shares,
which price shall be computed as the per Share closing price (if such
Shares are listed on an exchange) or the average between the per Share bid
and asked prices as of the close of business on the exercise date as
reported by the National Association of Securities Dealers Automated
Quotation System and the Purchase Price on the exercise date times the
fractional Share which is represented by the Warrants on the exercise date.
However, if no market price exists, then the amount of cash to be paid to
the registered holder of the Warrant in lieu of any fractional Shares shall
be the product of the difference between the per share Tangible Net Book
Value (defined hereafter) of the shares of the Company's Common Stock
outstanding on the last business day prior to the exercise date and the
Purchase Price on the exercise date times the fractional security which
otherwise would have been issuable in the absence of this provision.  For
purposes of payment of cash in lieu of the issuance of fractional
securities, the term "Tangible Net Book Value" means the consolidated total
shareholders' equity, determined in accordance with generally accepted
accounting principles ("GAAP"), less the aggregate net amount of the
following items to the extent, if any, that they were included in
consolidated assets or deducted from consolidated liabilities in computing
shareholders' equity:

            (i)     all franchises, licenses, patents, patent
                    applications, copyrights, trademarks, trade
                    names, goodwill, experimental or
                    organizational expense, unamortized debt
                    discount and expense, and all other assets
                    which under GAAP are deemed intangible; and,

           (ii)     any write-up of assets after December 31, 1994.

          The holder hereof, by accepting same, consents and agrees with
Company, Warrant Agent, and with every other holder of a Warrant
Certificate that:

          (A)  The Warrants evidenced by this Certificate are

                                                                  Page 155
               transferable only on the registry books of Warrant
               Agent upon surrender of this Certificate at the
               principal office of Warrant Agent, and only as
               provided in Section "4" of the Warrant Agreement;

          (B)  Company and Warrant Agent may deem and treat the
               person in whose name this Certificate is registered
               as the absolute owner thereof and of the Warrants
               evidenced thereby (notwithstanding any notations of
               ownership or writing on the Certificate made by
               anyone other than Company or Warrant Agent) for all
               purposes whatsoever, and neither Company nor
               Warrant Agent shall be affected by any notice to
               the contrary;

          (C)  Company and Warrant Agent may modify the terms of
               the Warrant Agreement from time to time as provided
               in Section "21" of the Warrant Agreement; and

          (D)  The terms contained in this Certificate are subject
               in all respects to the terms of the Warrant
               Agreement itself.

          This Certificate shall not be valid or obligatory for any purpose
until it has been countersigned by Warrant Agent.

          WITNESS the facsimile signatures of the proper officers of
Company and its corporate seal.  Dated as of July 28, 1995.

TGC Industries, Inc.
1304 Summit Avenue, Ste. 2
Plano, TX 75074

Gentlemen:

     We have acted as counsel to TGC Industries, Inc., a Texas corporation
(the "Company"), in connection with the proposed offering for sale by
certain selling security holders of 737,174 Warrants, issued pursuant to
that certain Warrant Agreement dated July 28, 1995, as amended ("Warrants"), 
1,150,350 shares of Series C 8% Convertible Exchangeable Preferred Stock 
("Preferred Stock"), and 900,506 shares of Common Stock (the "Selling Security 
Holder Common Stock").  We have also acted as counsel to the Company in
connection with the offering by the Company of 887,174 shares of Common 
Stock upon the exercise of all outstanding warrants of the Company and 
7,669,000 shares of Common Stock upon the conversion of all of the 
outstanding Preferred Stock (the "Company Common Stock").  The Warrants,
Preferred Stock, Selling Security Holder Common Stock and Company Common 
Stock are being registered under the Company's Registration Statement on 
Form SB-2 as filed with the Securities and Exchange Commission on 
September 18, 1996.  

     In our capacity as counsel to the Company, we have examined and relied
upon the Company's Articles of Incorporation and Bylaws, as amended, and
the records of corporate proceedings with respect to the approval of the
proposed registration, and have made such other investigations as we have
deemed necessary and prudent for the purposes of the opinions expressed
herein.

     Based on the foregoing, we are of the opinion that (1) the Warrants, the 
Preferred Stock and the Selling Security Holder Common Stock have been duly
authorized and validly issued and are fully paid and non-assessable, and
(2) the Company Common Stock has been duly authorized and, when issued upon 
exercise of outstanding warrants of the Company in accordance with their
terms, including the payment to the Company of the consideration for such
shares, and when issued upon conversion of the Preferred Stock in accordance 
with its terms, will be validly issued, fully paid and non-assessable.

     We hereby consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the aforesaid Registration
Statement and to the use of our name in the prospectus constituting a part
thereof.

                               Respectfully submitted,
