     Unless the context indicates otherwise, all references herein to the
"Company" or to "3-D Geophysical" mean 3-D Geophysical, Inc. and its
subsidiaries, the principal ones of which operate two seismic data acquisition
businesses (the "Operating Subsidiaries") -- Geovaluaciones, S.A. de C.V.
("Geovaluaciones") and Northern Geophysical of America, Inc. ("Northern"). In
addition, the Company processes seismic data through another subsidiary,
Procesos Interactivos Avanzados, S.A. de C.V. ("PIASA"). Concurrently with the
consummation of the Company's initial public offering (the "Initial Public
Offering") in February 1996, 3-D Geophysical acquired Geoevaluaciones, Northern,
Paragon Geophysical, Inc. ("Paragon") and Kemp Geophysical Corporation ("Kemp").
In December 1996, Paragon and Kemp were merged with and into Northern. Unless
the context indicates otherwise, certain technical and other terms used in this
Prospectus have the meanings assigned to them in the Glossary appearing
elsewhere herein.
    
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise indicated, all information
included in this Prospectus assumes that the Underwriters' over-allotment option
will not be exercised. In this Prospectus, unless otherwise indicated,
references to "dollars" and "$" are to United States dollars, references to
"pesos" are to Mexican pesos and references to "Canadian dollars" and "C$" are

                                  THE COMPANY
GENERAL
 
     3-D Geophysical, Inc. is one of the leading providers of land-based and
shallow water three-dimensional ("3-D") and two-dimensional ("2-D") seismic data
acquisition services to the oil and gas industry in the Western Hemisphere. As
of October 31, 1996, the Company's nine crews operated land-based and shallow
water seismic data acquisition systems, primarily utilizing state-of-the-art,
24-bit equipment, with a total of approximately 12,000 channels, in Alaska, the
Rocky Mountain, West Coast and Appalachian regions and in Mexico.
 
     The seismic data acquisition services industry is currently experiencing
several significant changes, including a continuing consolidation of service
providers. The Company believes that this consolidation is due in part to the
trend by oil and gas exploration and production companies to rely on third-party
seismic contractors to provide increasingly more sophisticated and extensive 3-D
seismic surveys. These surveys require a greater number of recording channels
and therefore substantial capital expenditures. This trend is rationalizing the
seismic services industry and creating a competitive advantage for companies
with extensive 3-D channel capacity and greater financial resources.
 
     The Company believes that (i) its state-of-the-art systems, (ii) its
ability to relocate equipment and crews among the regions in which it operates,
(iii) the regional experience of its management and crews in performing 3-D and
2-D surveys, and (iv) the quality of its services and relationships with
customers will enable the Company to take advantage of this industry trend.
 
     Since the Initial Public Offering, the Company has:
 
     - Increased its channel capacity from approximately 7,500 to approximately
       12,000 channels;
 
     - Expanded its operations in Alaska with seismic data acquisition contracts
       with Arco Alaska Inc., a subsidiary of Atlantic Richfield Company
       ("ARCO"), BP Exploration (Alaska) Inc. ("BP Alaska") and Marathon Oil
       Company ("Marathon");
 
     - Obtained two of the first group of 3-D seismic data acquisition contracts
       awarded to date by Petroleos Mexicanos ("PEMEX"), Mexico's national oil
       company;
 
     - Established a presence in Peru by opening a branch office and a seismic
       data processing center and bidding on several contracts to provide 
       seismic data acquisition services in Peru; and
 
   
     - Entered into a stock purchase agreement to acquire J.R.S. Exploration
       Company Limited ("J.R.S. Exploration"), a seismic data acquisition
       business that has been operating in Western Canada since

      1978 using up to four crews utilizing 24-bit seismic data acquisition
      systems with a total of approximately 2,000 channels.
 
  INDUSTRY OVERVIEW
 
     Seismic data is the principal source of information used by geoscientists
to map potential or existing oil and gas bearing formations and the geologic
structures that surround them. Seismic data is acquired over a specified area by
deploying a network of electronic cables over the area to which electronic
receivers, or geophones, are attached. Once this network is deployed, an energy
source, such as truck mounted vibrators ("vibroseis") or dynamite, is used to
generate seismic waves over a pre-determined set of frequencies that move
through the rock formation under the area and reverberate back to the surface in
milliseconds. The geophones capture the changing velocity and character of these
seismic waves as they travel down and back through the earth's surface and
transmit this information a short distance along an electrical path (a
"channel") to a remote signal conditioner. The remote signal conditioner
digitizes the analog data and transmits it to a central electronics unit that
stores the acquired data. The data is then sent to a processing center where
mathematical algorithms are applied to separate signals from interference and to
correct distortion. Migration techniques are also applied to produce a spatial
representation of the subsurface formations that were surveyed. After
processing, the data is transferred to a computer workstation that allows the
data to be viewed and reconfigured by a geoscientist who interprets the data
with computer-aided exploration techniques in order to plot features and map the
structures of the subsurface area.
 
     In the past, a 2-D survey was the standard technique utilized to acquire
seismic data. 2-D seismic data can be visualized as a single vertical plane of
subsurface information. 3-D seismic surveys produce data that is best visualized
as a cube of information that can be sliced into numerous planes. Thus, 3-D
surveys provide different views of a subsurface geologic structure and much
higher resolution of the structure than is available from a 2-D survey and have
proven to be more reliable indicators of the oil and gas potential in the area
surveyed. As a result, drilling based on 3-D seismic surveys has improved the
economics of finding oil and gas. Consequently, demand for 3-D seismic surveys,
and for surveys that cover wide areas and utilize a greater number of channels,
has increased in the past several years. Furthermore, due to the enhanced
information provided, 3-D surveys have proven to be a cost effective and
efficient tool for oil and gas exploration and, increasingly, the development of
existing reserves.
 
  BUSINESS STRATEGY
 
     The Company's objective is to capitalize on the consolidation taking place
in its industry to enhance its position as one of the leading providers of
land-based and shallow water seismic data acquisition services and to become a
significant provider of related services to the oil and gas industry in the
Western Hemisphere. The Company intends to achieve this objective by:
 
     - Optimizing the utilization of its state-of-the-art seismic data
       acquisition systems by relocating equipment and crews among the regions 
       in which the Company operates;
 
     - Expanding its operations in Mexico and elsewhere in Latin America by
       seeking further contract opportunities with PEMEX and other oil companies
       operating in Latin America;
 
     - Pursuing opportunities in the United States, including Alaska, by
       attempting to strengthen existing business relationships with
       multinational companies and their affiliates, such as ARCO, BP Alaska,
       Marathon and others;
 
     - Pursuing strategic acquisitions by seeking to acquire providers of
       seismic data acquisition and related services, such as J.R.S. 
       Exploration, that complement the Company's geographic market coverage 
       and growth strategy; and
 
     - Expanding the Company's data processing and interpretation and reservoir
       characterization services already being provided to PEMEX in Mexico into
       other markets.

         SUMMARY HISTORICAL AND PRO FORMA FINANCIAL AND OPERATING DATA
 
     On February 9, 1996, simultaneously with the consummation of the Initial
Public Offering, 3-D Geophysical acquired in separate transactions, in exchange
for cash, notes and shares of Common Stock, Geoevaluaciones, PIASA, Northern's
land-based seismic data operations, Paragon and Kemp. See "Certain
Transactions." For accounting purposes, the acquisitions of Geoevaluaciones and
PIASA were treated as a recapitalization of Geoevaluaciones and PIASA with
Geoevaluaciones (combined with PIASA) deemed to be the acquiror and predecessor
of 3-D Geophysical. Accordingly, the combined net assets of Geoevaluaciones and
PIASA were valued at historical cost and the consideration given to the former
stockholders of Geoevaluaciones and PIASA was treated for accounting purposes as
a dividend. The acquisitions of Northern's land-based seismic data operations,
Paragon and Kemp (the "Purchased Companies") were treated as business
combinations accounted for by the purchase method of accounting as prescribed by
Accounting Principles Board Opinion No. 16 and Securities and Exchange
Commission ("SEC") Staff Accounting Bulletin No. 48 (as applied prior to the
issuance of SAB 97) and are included within 3-D Geophysical's historical
consolidated statement of operations commencing February 9, 1996. The
acquisition of Paragon's common stock in exchange for shares of Common Stock was
accounted for at Paragon's historical cost. Northern's land-based seismic data
operations and Kemp were valued at the fair market value of consideration given.
In connection with the acquisitions of Northern's land-based seismic data
operations and Kemp, the excess of consideration given over the fair market
value of net assets is being amortized on a straight-line basis over 15 years.
For purposes of identification and description, the Company is referred to as
the "Predecessor" for the period prior to the Initial Public Offering and the
acquisition of the Purchased Companies as described below, the "Successor" for
the period subsequent to the Initial Public Offering and the acquisition of the
Purchased Companies and the "Company" for both periods.
 
     Summary historical financial data is provided for Geoevaluaciones and PIASA
on a combined basis because, as described in the preceding paragraph,
Geoevaluaciones and PIASA are considered the acquirors of the Purchased
Companies for accounting purposes and therefore are deemed to be the predecessor
of 3-D Geophysical. The historical financial information for each of the three
years ended December 31, 1995 and for the nine months ended September 30, 1995
was derived from financial statements appearing elsewhere in this Prospectus.
The historical financial information for the years ended December 31, 1991 and
1992 was derived from Geoevaluaciones' financial statements (1991 is unaudited)
which do not appear elsewhere in this Prospectus. The historical financial
information for the nine months ended September 30, 1996 represents combined
operations for the entire nine months for Geoevaluaciones and also includes
operations for the Purchased Companies for the period from February 9, 1996 to
September 30, 1996. As a result, the Successor's statement of operations for the
nine months ended September 30, 1996 is not comparable to the Predecessor's
statement of operations for the nine months ended September 30, 1995. The pro
forma consolidated statements of operations for the year ended December 31, 1995
and the nine months ended September 30, 1995 and 1996 assume that the Company
had completed the recapitalization, the acquisition of the Purchased Companies
and the Initial Public Offering on January 1, 1995. The following summary pro
forma statement of operations information was derived from the pro forma
consolidated financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. The pro forma consolidated statement of operations
data may not be indicative of actual results that would have been achieved if
the transactions had occurred on the dates indicated or the results which may be
realized in the future.
 
     The pro forma consolidated statement of operations information does not
include the effects of the proposed acquisition of J.R.S. Exploration and
certain related equipment (see "Business -- Proposed Acquisition of J.R.S.
Exploration"). For a presentation of the pro forma effects of this proposed
acquisition, see the adjusted pro forma consolidated financial statements,
including the notes thereto, appearing elsewhere in this Prospectus.
 
     The following summary financial data is qualified in its entirety by the
more detailed information appearing in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the consolidated financial
statements, including the notes thereto, appearing elsewhere in this Prospectus.

statements.
 
                                  RISK FACTORS
 
LIMITED COMBINED OPERATING HISTORY
 
     3-D Geophysical was incorporated in March 1995 and concurrently with the
Initial Public Offering in February 1996 acquired the Operating Subsidiaries and
PIASA. Prior to the Initial Public Offering, the Operating Subsidiaries operated
independently and neither the historical results of their separate operations
nor their pro forma financial information are necessarily indicative of the
results that would have been achieved had the Operating Subsidiaries been
operated on an integrated basis or the results that may be realized in the
future. Although members of management of the Company have extensive experience
in providing land-based and shallow water seismic data acquisition services and
in managing businesses that provide such services, there can be no assurance
that management will be able to implement the Company's operating and growth
strategies successfully. See "Management."
 
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 and abroad, the discovery rate of new oil and gas reserves in land
and shallow water 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. Beginning in 1982, a sharp decline in oil and gas
prices led to a worldwide reduction in oil and gas activities. This decline
resulted in a significant reduction in the overall demand for seismic services.
No assurance can be 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.
 
CAPITAL INTENSIVE BUSINESS; RAPID OBSOLESCENCE OF TECHNOLOGY
 
     The Company competes in a capital intensive industry. As the number of
channels per 3-D crew has increased significantly over the past few years, the
capital costs of fully equipping each crew have also increased. 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 either render the Company's current equipment obsolete or require the
Company to make significant incremental 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. Furthermore,
any significant increase in the level of the Company's operations may require it
to acquire additional data acquisition systems. To do so will likely require
large expenditures of capital in addition to the
 
                                        9
<PAGE>   12
 
Company's planned capital expenditures. There can be no assurance that the
Company will have the capital necessary to upgrade its equipment to maintain its
competitive position or to acquire any additional required equipment, or that
any required financing therefor will be available on favorable terms. If the
Company is unable to raise the capital necessary to update or increase the
capacity of its data acquisition systems to the extent necessary, it will be
unable to update such systems or increase its level of operations and may be
materially and adversely affected as a result. See "Use of Proceeds,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources," "Business -- Capital
Expenditures" and "Business -- Competition."
 
SUBSTANTIAL COMPETITION
 
     The Company has extensive competition in each of the regions in which it
operates. Competitive factors include price, crew experience, equipment
availability, technological expertise and reputation for dependability and
safety. Certain of the Company's major competitors have more crews and operate
data acquisition systems having significantly more channels than the Company,
provide integrated data acquisition, processing and interpretation services and
have 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 competitors for contracts to conduct seismic surveys.
See "Business -- Competition."
 
SUBSTANTIAL RISKS OF DOING BUSINESS IN LATIN AMERICA
 
     For the year ended December 31, 1995 and for the nine months ended
September 30, 1996, 26.0% and 22.7%, respectively, of the pro forma net revenues
of the Company resulted from the operations of Geoevaluaciones and PIASA in
Mexico (the "Mexican Operations"). The level of land-based seismic data
acquisition services in Mexico has in the past been vulnerable to economic
downturns and changes in government policies and public spending. Since December
1994, Mexico has experienced an economic crisis characterized by a significant
devaluation of the peso, exchange rate instability, increased inflation, high
domestic interest rates, negative economic growth, reduced consumer purchasing
power and high unemployment. Despite certain austerity measures, volatility in
the peso to dollar foreign exchange rate and financial markets persisted through
1995. The peso to dollar exchange rate (as published by Banco Mexicano de
Comercio Exterior) at the close of the last business day of 1993, 1994, 1995 and
on September 30, 1996 was 3.13, 5.00, 7.68 and 7.55, respectively. On October
31, 1996, such exchange rate was 8.05. Inflation in Mexico for the year ended
December 31, 1995 and for the nine months ended September 30, 1996 was
approximately 52.0% and 20.3%, respectively, based on the consumer price index.
 
     The December 1994 devaluation of the peso had a number of effects on the
Mexican economy that have adversely affected the financial condition of
businesses in Mexico, including the Mexican Operations. The devaluation caused
the peso value of dollar denominated indebtedness associated with the Mexican
Operations, which consists primarily of equipment financing, to increase
significantly, and also greatly increased the rate of inflation, resulting in a
sharp rise in nominal interest rates on peso denominated financing.
 
     The prices the Company pays for certain equipment, energy and other
materials for the Mexican Operations are set, in part, by reference to
international prices denominated in currencies other than pesos, and the results
of operations of the Mexican Operations, denominated in pesos, are translated
into dollars for inclusion in the Company's financial statements. However, the
operations and revenues of the Mexican Operations are primarily peso-denominated
and the Company has not hedged against currency risks in Mexico, except that
certain of the costs incurred by the Mexican Operations may be adjusted,
pursuant to the Company's contracts with PEMEX, to take into account economic
events such as inflation and devaluation of the peso (see "Business -- Marketing
and Customers -- Contracts"). The Company is subject to foreign exchange risks
primarily in connection with the conversion into dollars of the results of
operations of the
 
                                       10
<PAGE>   13
 
Mexican Operations. Increases in the peso to dollar exchange rate will result in
a reduction of the dollar value of peso-based revenues of the Company as well as
the dollar value of peso-based expenses of the Company. Likewise, decreases in
such rate will result in increases in the dollar value of such revenues and
expenses. As a result, such fluctuations could have a material adverse effect on
the financial condition and results of operations of the Company. The Company
does not currently employ any hedging method to reduce such foreign exchange
risks. While the Company may from time to time evaluate methods to reduce such
foreign exchange risks, the adoption of any particular method will depend on
existing market conditions. The Company cannot reasonably predict what method,
if any, it will adopt to reduce foreign exchange risks, and there can be no
assurance that it will adopt any such method or that, if adopted, any such
method will reduce such risks.
 
     There can be no assurance that future developments in the Mexican
political, economic, social or diplomatic condition, over which the Company has
no control, will not have a material adverse effect on the Company's financial
condition or results of operations or the market price of its securities.
 
     In June 1996, the Company established a branch and opened a seismic data
processing center in Peru. In September 1996, the Company entered into a
contract to provide land-based seismic data acquisition services there; however,
this contract is subject to the resolution of certain uncertainties relating to
obtaining required local permits. The Company intends to continue to seek
expansion opportunities in Peru and other countries in Latin America. In
general, so long as the Company derives a significant portion of its revenues
outside the United States, in addition to currency risks, the Company will be
subject to risks associated with international operations, including war, civil
disturbance and government activity, which may limit or disrupt the Company's
operations.
 
DEPENDENCE ON SIGNIFICANT CUSTOMER
 
     26.0% and 22.7% of the pro forma net revenues of the Company for the year
ended December 31, 1995 and nine months ended September 30, 1996, respectively,
and in excess of 95% of the net revenues of the Mexican Operations in those
periods, were derived from land-based seismic data acquisition services provided
to PEMEX. The loss of PEMEX as a customer would have a material adverse effect
on the Company's financial condition and results of operations. See
"Business -- Marketing and Customers -- Customers."
 
RELIANCE ON KEY SUPPLIER
 
     The Company is dependent on Input/Output, Inc. ("Input/Output") for
additions to and replacements for its I/O SYSTEM TWO(R) seismic data acquisition
systems. Although Input/Output is not the only supplier of seismic data
acquisition systems, it is the Company's primary supplier and the Company
considers Input/Output's systems to be among the state-of-the-art seismic data
acquisition systems for performing 3-D seismic surveys on land and in shallow
water. Therefore, should a system be substantially damaged, or should a
significant systems failure occur, and should Input/Output be unwilling or
unable to furnish replacement parts or otherwise repair such systems, the
Company may be unable to obtain such replacements from other sources and would
have to acquire other equipment that may be less advanced technologically.
Although the Company believes it will be able to obtain systems from
Input/Output or another source of state-of-the-art seismic data acquisition
systems in the future, should it be unable to do so, the Company's anticipated
revenues could be reduced significantly and the amount of cash needed for
capital expenditures could be increased significantly. See "Business -- Capital
Expenditures."
 
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. Fixed costs, including costs associated with
operating leases, labor costs and depreciation, account for more than half of
the Company's costs and expenses. 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,
 
                                       11
<PAGE>   14
 
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. For example, no
insurance is available at a cost deemed reasonable by the Company for war,
nationalization, appropriation or other extreme events. See
"Business -- Operating Conditions" and "Business -- Marketing and
Customers -- Contracts."
 
RELIANCE ON KEY PERSONNEL
 
     The Company's operations are dependent on the efforts of Messrs. Richard
Davis, Luis Ferran, Joel Friedman, Ronald Koons, Charles Merchant and Wayne
Widynowski. 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. See "Management."

upon the exercise of options granted under the Plan or otherwise to officers,
directors and other key employees of the Company). The 1,400,681 shares of
Common Stock issued in connection with the founding of 3-D Geophysical will be
eligible for resale in the public market commencing in March 1997 and the
1,599,319 shares of Common Stock issued to the former stockholders of the
Operating Subsidiaries and PIASA simultaneously with the consummation of the
Initial Public Offering will be eligible for resale in the public market
commencing in February 1998, subject in each case to certain volume and other
restrictions provided for in Rule 144 ("Rule 144") promulgated under the
Securities Act of 1933, as amended (the "Securities Act"). The Company has
granted pursuant to the Plan options to purchase an aggregate of 624,350 shares
of Common Stock and has granted options to purchase an additional aggregate of
265,002 shares of Common Stock other than pursuant to the Plan to certain
directors and key employees of the Company (see "Management -- Director
Compensation" and "Management -- Long-Term Incentive Compensation Plan"). The
Company intends to register under the Securities Act the shares issuable upon
exercise of such options and, upon such registration, such shares will be
eligible for resale in the public market, except that any such shares issued to
affiliates are subject to certain restrictions under Rule 144.
 
     Sales of substantial amounts of the Common Stock in the public market could
adversely affect prevailing market prices and the ability of the Company to
raise equity capital in the future. See "Shares Eligible for Future Sale" and
"Underwriting."
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION,
BY-LAWS AND DELAWARE GENERAL CORPORATION LAW
 
     Certain provisions of the Certificate of Incorporation and By-laws may tend
to deter potential unsolicited offers or other efforts to obtain control of the
Company that are not approved by the Board of Directors. Such provisions may
therefore deprive the stockholders of opportunities to sell shares of Common
Stock at prices higher than prevailing market prices. See "Description of
Capital Stock -- Certain Anti-Takeover Effects of Certain Provisions of the
Certificate of Incorporation, By-laws and Delaware General Corporation Law."

                                  THE COMPANY
 
     3-D Geophysical, Inc. is one of the leading providers of land-based and
shallow water 3-D and 2-D seismic data acquisition services to the oil and gas
industry in the Western Hemisphere. As of October 31, 1996, the Company's nine
crews operated land-based and shallow water seismic data acquisition systems,
primarily utilizing state-of-the-art, 24-bit equipment, with a total of
approximately 12,000 channels, in Alaska, the Rocky Mountain, West Coast and
Appalachian regions and in Mexico.
 
   
     3-D Geophysical, Inc., a Delaware corporation, was incorporated in March
1995. The Company's principal offices are located at 7076 South Alton Way,
Building H, Englewood, Colorado 80112, and its telephone number is (303)
290-0214.
    
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 4,300,000 shares of
Common Stock offered hereby, after deducting the underwriting discount and
estimated expenses of this Offering to be paid by the Company, are estimated to
be approximately $     million ($     million if the Underwriters'
over-allotment option is exercised in full). The Company anticipates that it
will use the net proceeds for the following purposes: (i) approximately $17.2
million to purchase additional systems, additional channel capacity for the six
24-bit seismic data acquisition systems it presently owns and related vehicles
and equipment to enhance the Company's 3-D seismic data acquisition capacity;
(ii) approximately $2.7 million to pay the cash portion of the purchase price
for J.R.S. Exploration (and certain related equipment) and approximately $1.3
million to repay debt of J.R.S. Exploration to a commercial bank (see
"Business -- Proposed Acquisition of J.R.S. Exploration"); (iii) approximately
$6.0 million to repay indebtedness incurred in connection with the Company's
purchase in May 1996 of two 24-bit seismic data acquisition systems; and (iv)
the balance, if any, for working capital and other general corporate purposes.
    
 
     The additional systems and equipment referred to in clause (i) above
include a 1,000 channel seismic data acquisition system and certain equipment
that are is presently leased from The Andrews Group International, Inc. under
leases that contain a purchase option. See "Use of Proceeds,"
"Business -- Capital Expenditures" and "Certain Transactions." The indebtedness
referred to in clause (iii) above consists of a portion of the $12 million
borrowed under a term loan from First Interstate Bank of Texas, N.A. that
matures on July 31, 1999 and bears interest at an annual rate equal to the prime
rate plus 1%. See "Capitalization" and "Business -- Capital Expenditures."
 
     The Company may revise its plans in response to future changes in the oil
and gas industry in general and the demand for its services in particular, its
results of operations, its other capital requirements and other relevant
factors. Until the proceeds are utilized as set forth above, the Company intends
to invest the net proceeds of this Offering in money market obligations,
certificates of deposit or other short-term, interest bearing securities.
 
                                DIVIDEND POLICY
 
   
     The Company intends to retain its earnings, if any, to finance the
expansion of its business and for general corporate purposes and does not
anticipate paying any cash dividends on the Common Stock in the foreseeable
future. Any payment of future dividends will be at the discretion of the Board
of Directors and will depend upon, among other things, the Company's earnings,
financial condition, capital requirements, level and terms of indebtedness,
contractual restrictions with respect to the payment of dividends and other
factors that the Board of Directors may deem relevant. The Company is a party to
a loan agreement that restricts the payment of dividends and certain other
matters. See "Capitalization," "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and "Business -- Capital Expenditures."

    Interstate Bank of Texas, N.A. (the "Bank") pursuant to a Loan Agreement
    between the Company and the Bank, dated as of May 29, 1996 (the "Loan

         SELECTED HISTORICAL AND PRO FORMA FINANCIAL AND OPERATING DATA
 
     On February 9, 1996, simultaneously with the consummation of the Initial
Public Offering, 3-D Geophysical acquired in separate transactions, in exchange
for cash, notes and shares of Common Stock, Geoevaluaciones, PIASA, Northern's
land-based seismic data operations, Paragon and Kemp. See "Certain
Transactions." For accounting purposes, the acquisitions of Geoevaluaciones and
PIASA were treated as a recapitalization of Geoevaluaciones and PIASA with
Geoevaluaciones (combined with PIASA) deemed to be the acquiror and predecessor
of 3-D Geophysical. Accordingly, the combined net assets of Geoevaluaciones and
PIASA were valued at historical cost and the consideration given to the former
stockholders of Geoevaluaciones and PIASA was treated for accounting purposes as
a dividend. The acquisitions of Northern's land-based seismic data operations,
Paragon and Kemp (the "Purchased Companies") were treated as business
combinations accounted for by the purchase method of accounting as prescribed by
Accounting Principles Board Opinion No. 16 and SEC Staff Accounting Bulletin No.
48 (as applied prior to the issuance of SAB 97) and are included within 3-D
Geophysical's historical consolidated statement of operations commencing
February 9, 1996. The acquisition of Paragon's common stock in exchange for
shares of Common Stock was accounted for at Paragon's historical cost.
Northern's land-based seismic data operations and Kemp were valued at the fair
market value of consideration given. In connection with the acquisitions of
Northern's land-based seismic data operations and Kemp, the excess of
consideration given over the fair market value of net assets is being amortized
on a straight-line basis over 15 years. For purposes of identification and
description, the Company is referred to as the "Predecessor" for the period
prior to the Initial Public Offering and the acquisition of the Purchased
Companies as described below, the "Successor" for the period subsequent to the
Initial Public Offering and the acquisition of the Purchased Companies and the
"Company" for both periods.
 
     Selected historical financial data is provided for Geoevaluaciones and
PIASA on a combined basis because, as described in the preceding paragraph,
Geoevaluaciones and PIASA are considered the acquirors of the Purchased
Companies for accounting purposes and therefore are deemed to be the predecessor
of 3-D Geophysical. The historical financial information for each of the three
years ended December 31, 1995 and for the nine months ended September 30, 1995
was derived from financial statements appearing elsewhere in this Prospectus.
The historical financial information for the years ended December 31, 1991 and
1992 was derived from Geoevaluaciones' financial statements (1991 is unaudited)
which do not appear elsewhere in this Prospectus. The historical financial
information for the nine months ended September 30, 1996 represents combined
operations for the entire nine months for Geoevaluaciones and also includes
operations for the Purchased Companies for the period from February 9, 1996 to
September 30, 1996. As a result, the Successor's statement of operations for the
nine months ended September 30, 1996 is not comparable to the Predecessor's
statement of operations for the nine months ended September 30, 1995. The pro
forma consolidated statements of operations for the year ended December 31, 1995
and the nine months ended September 30, 1995 and 1996 assume that the Company
had completed the recapitalization, the acquisition of the Purchased Companies
and the Initial Public Offering on January 1, 1995. The following selected pro
forma statement of operations information was derived from the pro forma
consolidated financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. The pro forma consolidated statement of operations
data may not be indicative of actual results that would have been achieved if
the transactions had occurred on the dates indicated or the results which may be
realized in the future.
 
     The pro forma consolidated statement of operations information does not
include the effects of the proposed acquisition of J.R.S. Exploration and
certain related equipment (see "Business -- Proposed Acquisition of J.R.S.
Exploration"). For a presentation of the pro forma effects of this proposed
acquisition, see the adjusted pro forma consolidated financial statements,
including the notes thereto, appearing elsewhere in this Prospectus.
 
     The following selected financial data is qualified in its entirety by the
more detailed information appearing in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the consolidated financial
statements, including the notes thereto, appearing elsewhere in this Prospectus.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following discussion has been divided into several sections: the first
section contains the pro forma results of operations for the four Operating
Subsidiaries and PIASA for the periods indicated based on the pro forma
consolidated financial statements of the Operating Subsidiaries, PIASA and 3-D
Geophysical assuming the Initial Public Offering was consummated and the
Operating Subsidiaries and PIASA were acquired on January 1, 1994. The second
section contains a discussion of the combined financial statements of the
Company for the periods indicated. For accounting purposes, the Mexican
Operations are considered the predecessor company, and the combined financial
statements include the operating results of the Mexican Operations for all the
periods and the operating results of the Purchased Companies only for the period
beginning February 9, 1996. As a result, the Company's statement of operations
for the nine months ended September 30, 1996 is not comparable to the statement
of operations for the nine months ended September 30, 1995. Finally, there is a
discussion of the liquidity and capital resources of the Company, the impact of
the Mexican economy and certain other matters. The following discussion of the
results of operations and the financial position of 3-D Geophysical and of the
Operating Subsidiaries and PIASA should be read in connection with "Selected
Historical and Pro Forma Financial and Operating Data," and the financial
statements, including the notes thereto, appearing elsewhere in this Prospectus.
    
 
PRO FORMA RESULTS OF OPERATIONS
 
  Nine Months Ended September 30, 1996 Compared to Nine Months Ended September
30, 1995
 
     NET REVENUES. Pro forma net revenues for the Company increased 55.7% to
$40.0 million in the nine months ended September 30, 1996 from $25.7 million in
the nine months ended September 30, 1995. The increase is primarily the result
of an increase in seismic survey activities in the United States. Pro forma net
revenues in the United States increased 66.9% to $30.9 million in the nine
months ended September 30, 1996 from $18.5 million in the nine months ended
September 30, 1995. The increase is primarily the result of increased seismic
survey activities in Alaska and the Rocky Mountain region. Pro forma net
revenues for the Mexican Operations increased 27.0% to $9.1 million in the nine
months ended September 30, 1996 from $7.2 million in the nine months ended
September 30, 1995 due primarily to inflation. The $7.2 million of net revenues
in the nine months ended September 30, 1995 for the Mexican Operations include
$2.6 million of contractual price adjustments related to increased costs due to
the devaluation of the peso which occurred in December 1994. Net revenues in the
nine months ended September 30, 1996 include similar contractual adjustments of
$1.1 million.
 
     COST OF DATA ACQUISITION. Pro forma cost of data acquisition for the
Company increased 57.8% to $30.1 million in the nine months ended September 30,
1996 from $19.1 million in the nine months ended September 30, 1995. The
increase is primarily the result of increased seismic survey activities in the
United States. Pro forma cost of data acquisition in the United States increased
50.8% to $23.1 million in the nine months ended September 30, 1996 from $15.3
million in the nine months ended September 30, 1995 due to greater activity in
Alaska and the Rocky Mountain region. Pro forma cost of data acquisition for the
Mexican Operations increased 86.4% to $7.0 million in the nine months ended
September 30, 1996 from $3.8 million in the nine months ended September 30,
1995. The decrease in gross margin for the Mexican Operations is primarily
attributable to larger price adjustments realized in the nine months ended
September 30, 1995 and the impact in the nine months ended September 30, 1996 of
a drilling and field services crew operating in Southern Mexico which did not
commence work in 1995 until November.
 
     DEPRECIATION AND AMORTIZATION. Pro forma depreciation and amortization for
the Company increased 21.3% to $3.1 million in the nine months ended September
30, 1996 from $2.5 million in the nine months ended September 30, 1995. This
increase is primarily the result of the acquisition of new equipment.
Depreciation and amortization for the Mexican Operations increased 27.1% to
$675,000 in the nine months ended September 30, 1996 from $531,000 in the nine
months ended September 30, 1995.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. Pro forma general and administrative
expenses for the Company increased 38.1% to $4.3 million in the nine months
ended September 30, 1996 from $3.1 million in the nine months ended September
30, 1995. The increase is primarily the result of the establishment of a 3-D
 
                                       18
<PAGE>   21
 
Geophysical headquarters, added costs associated with being a publicly traded
company and increased marketing costs. Pro forma general and administrative
expenses in the United States increased 50.7% to $3.4 million in the nine months
ended September 30, 1996 from $2.3 million in the nine months ended September
30, 1995. Pro forma general and administrative expenses for the Mexican
Operations increased 4.0% to $866,000 in the nine months ended September 30,
1996 from $833,000 in the nine months ended September 30, 1995. The increase in
general and administrative expenses in the Mexican Operations is attributable
primarily to the costs of evaluating business opportunities in Latin America.
 
     OPERATING INCOME. Pro forma operating income for the Company increased
159.6% to $2.6 million in the nine months ended September 30, 1996 from $983,000
in the nine months ended September 30, 1995. The increase is primarily related
to improvements in the operations in the United States which recognized an
operating profit of $2.0 million in the nine months ended September 30, 1996
compared to a loss of $1.1 million in the nine months ended September 30, 1995.
Pro forma operating income for the Mexican Operations decreased 73.5% to
$540,000 in the nine months ended September 30, 1996 from $2.0 million in the
nine months ended September 30, 1995. The decrease is primarily attributable to
a $2.6 million price adjustment realized in the nine months ended September 30,
1995 as a result of contractual adjustments relating to the devaluation of the
peso in December 1994. Similar contractual adjustments of $1.1 million were
realized in the nine months ended September 30, 1996.
 
     INTEREST EXPENSE. The Company's pro forma interest expense decreased 5.6%
to $710,000 in the nine months ended September 30, 1996 from $752,000 in the
nine months ended September 30, 1995. The decline in interest expense is
attributable to lower borrowing costs for the Mexican Operations compared with
the nine months ended September 30, 1995.
 
     FOREIGN CURRENCY TRANSACTION GAINS (LOSSES). The Company recognized pro
forma foreign currency gains of $8,000 in the nine months ended September 30,
1996 compared to foreign currency losses of $83,000 in the nine months ended
September 30, 1995. The gains are attributable to the reduction of dollar
liabilities of the Mexican Operations and the fluctuation of the peso to dollar
exchange rate.
 
     MISCELLANEOUS INCOME (EXPENSE). The Company recognized pro forma
miscellaneous income of $437,000 in the nine months ended September 30, 1996
compared to miscellaneous expense of $68,000 in the nine months ended September
30, 1995. The increase is primarily the result of interest income in Mexico due
to the high investment interest rates available in Mexico, interest income from
the investment of the proceeds of the Initial Public Offering and interest
income from the conversion of a trade receivable to an interest-bearing note
receivable, which was paid in July 1996.
 
     INCOME TAX EXPENSE (BENEFIT). The Company recognized pro forma income tax
expense of $511,000 in the nine months ended September 30, 1996 compared to pro
forma income tax benefit of $390,000 in the nine months ended September 30,
1995. The increase is attributable to earnings increases in the operations in
the United States and a higher effective tax rate in the Mexican Operations due
to lower inflation adjustments.
 
   
     The Company believes that it is probable that the inflation rate in Mexico,
as measured by the consumer price index, will exceed 100% for the three-year
period ending December 31, 1996. Accordingly, the Company will likely adopt the
U.S. dollar as the functional currency for the Mexican Operations beginning on
January 1, 1997 in accordance with Statement of Financial Accounting Standards
No. 52. Using the U.S. Dollar as the functional currency will result in an
adjustment to the consolidated statement of operations for translation gains and
losses.
    
 
  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
     NET REVENUES. Pro forma net revenues for the Company decreased 9.1% to
$37.8 million for the year ended December 31, 1995 from $41.6 million for the
year ended December 31, 1994. The decline is primarily the result of decreased
seismic survey activities in the Mexican Operations partially offset by an
increase in survey activities in the United States. Pro forma net revenues in
the United States increased 17.0% to $28.0 million for the year ended December
31, 1995 from $23.9 million for the year ended December 31, 1994. The increase
is primarily attributable to operations in the Rocky Mountain region where
revenues
 
                                       19
<PAGE>   22
 
increased 29.0% to $19.9 million. Pro forma net revenues for the Mexican
Operations decreased 44.4% to $9.8 million for the year ended December 31, 1995
from $17.6 million for the year ended December 31, 1994. The decline in net
revenues in the Mexican Operations is attributable primarily to the devaluation
of the peso as well as the decline in demand for seismic surveys by PEMEX in
1995 due to the economic turmoil in Mexico in 1995 and PEMEX's internal
transition from 2-D to 3-D as its primary seismic survey technique.
 
     COST OF DATA ACQUISITION. Pro forma cost of data acquisition for the
Company increased 1.3% to $28.9 million for the year ended December 31, 1995
from $28.6 million for the year ended December 31, 1994. The increase is
primarily the result of increased seismic survey activities in the United
States. The increase in the cost of data acquisition in the United States was
partially offset by a decline in survey activities in the Mexican Operations.
Pro forma cost of data acquisition in the United States increased 30.8% to $23.0
million for the year ended December 31, 1995 from $17.6 million for the year
ended December 31, 1994. The increase is primarily attributable to significant
equipment rental expenses in the Rocky Mountain region. Pro forma cost of data
acquisition for the Mexican Operations decreased 45.8% to $6.0 million for the
year ended December 31, 1995 from $11.0 million for the year ended December 31,
1994. The decline in cost of data acquisition in the Mexican Operations is
attributable primarily to the devaluation of the peso and to a lesser extent is
attributable to decreases in personnel due the decline in demand for seismic
surveys by PEMEX in 1995.
 
     DEPRECIATION AND AMORTIZATION. Pro forma depreciation and amortization for
the Company decreased 19.5% to $3.4 million for the year ended December 31, 1995
from $4.3 million for the year ended December 31, 1994. The decrease is
primarily the result of the devaluation of the peso which was partially offset
by capital expenditures in the operations in the United States. Pro forma
depreciation and amortization in the United States remained relatively unchanged
at $2.8 million for the year ended December 31, 1995 from the year ended
December 31, 1994. Pro forma depreciation and amortization for the Mexican
Operations decreased 54.9% to $662,000 for the year ended December 31, 1995 from
$1.5 million for the year ended December 31, 1994, primarily due to the
devaluation of the peso and to a lesser extent decreases in capital
expenditures.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. Pro forma general and administrative
expenses for the Company decreased 6.7% to $4.3 million for the year ended
December 31, 1995 from $4.6 million for the year ended December 31, 1994. The
decrease is primarily the result of decreased general and administrative
expenses for the Mexican Operations due the devaluation of the peso, partially
offset by increased overhead in the operations in the United States. Pro forma
general and administrative expenses in the United States increased 16.8% to $3.3
million for the year ended December 31, 1995 from $2.8 million for the year
ended December 31, 1994. Pro forma general and administrative expenses for the
Mexican Operations decreased 42.8% to $1.0 million for the year ended December
31, 1995 from $1.8 million for the year ended December 31, 1994. The decline in
general and administrative expenses for the Mexican Operations is attributable
primarily to the devaluation of the peso and to a lesser extent decreases in
personnel due to the decline in demand for seismic surveys by PEMEX in 1995.
 
     OPERATING INCOME. Pro forma operating income for the Company decreased
71.9% to $1.2 million for the year ended December 31, 1995 from $4.2 million for
the year ended December 31, 1994. Pro forma operating income in the United
States decreased to a loss of $982,000 for the year ended December 31, 1995 from
operating income of $801,000 for the year ended December 31, 1994. The losses in
the United States were primarily attributable to a decline in seismic activities
in the Rocky Mountain region in the first half of 1995. Pro forma operating
income for the Mexican Operations decreased 36.1% to $2.2 million for the year
ended December 31, 1995 from $3.4 million for the year ended December 31, 1994.
The decline in operating income in the Mexican Operations is attributable
primarily to the devaluation of the peso as well as the decline in demand for
seismic surveys by PEMEX in 1995 due to the economic turmoil in Mexico in 1995
as well as PEMEX's internal transition from 2-D to 3-D as its primary seismic
survey technique.
 
     INTEREST EXPENSE. The Company recognized pro forma interest expense of $1.1
million for the year ended December 31, 1995 compared to $625,000 for the year
ended December 31, 1994. The increase is primarily due to increased debt levels
at Paragon.

<PAGE>   23
 
     FOREIGN CURRENCY TRANSACTION GAINS (LOSSES). The Company recognized pro
forma foreign currency losses of $120,000 for the year ended December 31, 1995
compared to foreign currency losses of $92,000 for the year ended December 31,
1994.
 
     MISCELLANEOUS INCOME (EXPENSE). The Company recognized pro forma
miscellaneous income of $415,000 for the year ended December 31, 1995 compared
to pro forma miscellaneous income of $77,000 for the year ended December 31,
1994. The increase is primarily the result of interest income in Mexico due to
high interest rates and a gain on sale of equipment in Mexico.
 
     INCOME TAX EXPENSE (BENEFIT). The Company recognized a pro forma income tax
benefit of $357,000 for the year ended December 31, 1995 compared to a pro forma
income tax expense of $1.2 million for the year ended December 31, 1994. The tax
benefit is attributable to losses incurred in the United States at an effective
tax rate of 37% partially offset by earnings from the Mexican Operations taxed
at an adjusted effective tax rate of 7.5%. The effective tax rate in Mexico for
the year ended December 31, 1995 was lower than the 34% statutory rate due to
favorable inflation adjustments.
 
COMBINED RESULTS OF OPERATIONS
 
  Nine Months Ended September 30, 1996 compared to Nine Months Ended September
30, 1995
 
     NET REVENUES. Net revenues for the Company increased 405.1% to $36.2
million in the nine months ended September 30, 1996 from $7.2 million in the
nine months ended September 30, 1995. The increase is primarily attributable to
the inclusion of $27.0 million of net revenues of the Company's operations in
the United States and a 27.0% increase to $9.1 million in the nine months ended
September 30, 1996, from $7.2 million in the nine months ended September 30,
1995, for the Mexican Operations. Net revenues for the Mexican Operations in the
nine months ended September 30, 1995 include $2.6 million of contractual
adjustments related to increased costs due to the devaluation of the peso which
occurred in December 1994. Net revenues for the Mexican Operations in the nine
months ended September 30, 1996 include similar contractual adjustments of $1.1
million.
 
     COST OF DATA ACQUISITION. Cost of data acquisition for the Company
increased 606.7% to $26.6 million in the nine months ended September 30, 1996
from $3.8 million in the nine months ended September 30, 1995. The increase is
primarily attributable to the inclusion of $19.6 million of cost of data
acquisition of the Company's operations in the United States and a 86.4%
increase to $7.0 million in the nine months ended September 30, 1996, from $3.8
million in the nine months ended September 30, 1995, for the Mexican Operations.
The decrease in gross margin for the Mexican Operations is primarily
attributable to larger price adjustments realized in the nine months ended
September 30, 1995 and the impact in the nine months ended September 30, 1996 of
a drilling and field services crew operating in Southern Mexico which did not
commence work in 1995 until November.
 
     DEPRECIATION AND AMORTIZATION. Depreciation and amortization for the
Company increased 425.0% to $2.8 million in the nine months ended September 30,
1996 from $531,000 in the nine months ended September 30, 1995. The increase is
primarily attributable to the inclusion of $2.0 million of depreciation and
amortization of the Company's operations in the United States, including
$260,000 of goodwill amortization attributable to the acquisitions of Northern
and Kemp. This is in addition to a 27.1% increase to $675,000 in the nine months
ended September 30, 1996, from $531,000 in the nine months ended September 30,
1995, for the Mexican Operations.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
for the Company increased 369.0% to $3.9 million in the nine months ended
September 30, 1996 from $833,000 in the nine months ended September 30, 1995.
The increase is primarily attributable to the inclusion of $2.9 million of
general and administrative expenses from the Company's operations in the United
States, and a 4.0% increase to $866,000 in the nine months ended September 30,
1996, from $833,000 in the nine months ended September 30, 1995, for the Mexican
Operations. General and administrative expenses for the Company have also
increased due to the establishment of a 3-D Geophysical headquarters, added
costs associated with being a publicly traded company and increased marketing
costs.
 
                                       21
<PAGE>   24
 
     OPERATING INCOME. Operating income for the Company increased 42.2% to $2.9
million in the nine months ended September 30, 1996 from $2.0 million in the
nine months ended September 30, 1995. The operating income of the Mexican
Operations decreased 73.4% to $540,000 in the nine months ended September 30,
1996 from $2.0 million in the nine months ended September 30, 1995. The decrease
in the operating income of the Mexican Operations in the nine months ended
September 30, 1996 is due to contractual revenue adjustments of $2.6 million,
which were realized in the nine months ended September 30, 1995, attributable to
increased costs resulting from the devaluation of the peso during December 1994.
This is contrasted with contractual adjustments of $1.1 million in the nine
months ended September 30, 1996. The decrease in the operating income of the
Mexican Operations was partially offset by the inclusion of $2.3 million of
operating income for the Company's operations in the United States in the nine
months ended September 30, 1996.
 
     INTEREST EXPENSE. The Company's interest expense increased 18.9% to
$668,000 in the nine months ended September 30, 1996 from $562,000 in the nine
months ended September 30, 1995. The increase is due to interest charges on
borrowings of approximately $12 million in May 1996 under a credit facility with
the Company's principal lender compared to interest charges on borrowings of
approximately $300,000 and financing charges in connection with the factoring of
receivables arising out of the Mexican Operations in the nine months ended
September 30, 1995.
 
     FOREIGN CURRENCY TRANSACTION GAINS (LOSSES). The Company recognized a
foreign currency gain of $8,000 in the nine months ended September 30, 1996
compared to a foreign currency loss of $83,000 in the nine months ended
September 30, 1995. These gains and losses are primarily attributable to the
reduction of dollar liabilities of the Mexican Operations and the fluctuation of
the peso to dollar exchange rate.
 
     MISCELLANEOUS INCOME (EXPENSE). The Company recognized miscellaneous income
of $437,000 in the nine months ended September 30, 1996 compared to
miscellaneous income of $38,000 in the nine months ended September 30, 1995. The
increase is primarily the result of interest income in Mexico due to the high
investment interest rates available in Mexico, interest income from the
investment of the proceeds of the Initial Public Offering and interest income
from the conversion of a trade receivable to an interest-bearing note receivable
which was paid in July 1996.
 
     INCOME TAX EXPENSE (BENEFIT). The Company recognized income tax expense of
$645,000 in the nine months ended September 30, 1996 compared to income tax
expense of $81,000 in the nine months ended September 30, 1995. The increase is
primarily attributable to earnings of the Company's operations in the United
States taxed at a 26% effective tax rate, partially offset by an 18% effective
tax rate for earnings from the Mexican Operations. The lower tax rate in Mexico
is due to inflation adjustments. The effective tax rate for the Company's
operations in the United States is lower than the statutory tax rate due to the
anticipated change in the valuation allowance previously established with
respect to certain net operating loss carryforwards.
 
     EXTRAORDINARY ITEM NET OF INCOME TAX EXPENSE. The Company recognized a
$57,000 extraordinary item in the nine months ended September 30, 1996, net of
tax expense of $36,000. The extraordinary item is due to a gain recognized on
the early extinguishment of debt. No extraordinary items were recognized in the
nine months ended September 30, 1995.
 
  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
     NET REVENUES. Net revenues decreased 44.4% to $9.8 million in the year
ended December 31, 1995 from $17.7 million in the year ended December 31, 1994.
The decline in net revenues was attributable primarily to the devaluation of the
peso as well as the decline in demand for seismic surveys by PEMEX in 1995 due
to the economic turmoil in Mexico in 1995 as well as PEMEX's internal transition
from 2-D to 3-D as its primary seismic survey technique.
 
     COST OF DATA ACQUISITION. Cost of data acquisition decreased 45.8% to $6.0
million in the year ended December 31, 1995 from $11.0 million in the year ended
December 31, 1994. The decline in cost of data
 
                                       22
<PAGE>   25
 
acquisition in the Mexican Operations is attributable primarily to the
devaluation of the peso and to a lesser extent decreases in personnel due the
decline in demand for seismic surveys by PEMEX in 1995.
 
     DEPRECIATION AND AMORTIZATION. Depreciation and amortization decreased
54.9% to $662,000 in the year ended December 31, 1995 from $1.5 million in the
year ended December 31, 1994. The decline in depreciation and amortization in
the Mexican Operations is attributable primarily to the devaluation of the peso
and to a lesser extent decreases in capital expenditures.
 
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
decreased 42.8% to $1.0 million in the year ended December 31, 1995 from $1.8
million in the year ended December 31, 1994. The decline in general and
administrative expenses in the Mexican Operations is attributable primarily to
the devaluation of the peso and to a lesser extent decreases in personnel due to
the decline in demand for seismic surveys by PEMEX in 1995.
 
     OPERATING INCOME. Operating income decreased 36.1% to $2.2 million in the
year ended December 31, 1995 from $3.4 million in the year ended December 31,
1994. The decline in operating income in the Mexican Operations is attributable
primarily to the devaluation of the peso as well as the decline in demand for
seismic surveys by PEMEX in 1995 due to the economic turmoil in Mexico in 1995
as well as PEMEX's internal transition from 2-D to 3-D as its primary seismic
survey technique.
 
     INTEREST EXPENSE. Interest expense increased 72.3% to $803,000 in the year
ended December 31, 1995 from $466,000 in the year ended December 31, 1994. The
increase in interest expense is attributable to higher borrowing costs in 1995
due to the economic impact of the devaluation of the peso and financing charges
in connection with the factoring of receivables arising out of the Mexican
Operations in the nine months ended September 30, 1995.
 
     FOREIGN CURRENCY TRANSACTION GAINS (LOSSES). Foreign currency losses of
$120,000 were recognized in the year ended December 31, 1995 compared to foreign
currency losses of $92,000 in the year ended December 31, 1994.
 
     MISCELLANEOUS INCOME (EXPENSE). Miscellaneous income of $503,000 was
recognized in the year ended December 31, 1995 compared to miscellaneous income
of $87,000 in the year ended December 31, 1994. The increase is primarily the
result of interest income in Mexico due to high interest rates and a gain on the
sale of equipment.
 
     INCOME TAX EXPENSE (BENEFIT). Income tax expense was $130,000 in the year
ended December 31, 1995 compared to income tax expense of $1.0 million in the
year ended December 31, 1994. The decline is attributable to lower earnings and
inflation adjustments to the 35% tax rate in Mexico which reduced the effective
tax rate to 7.5%.
 
  Year Ended December 31, 1994 Compared to Year Ended December 31, 1993
 
     NET REVENUES. Net revenues of $17.7 million in 1994 remained relatively
unchanged from 1993 due to greater utilization of Geoevaluaciones' heliportable
crew operating in Central Mexico and Geoevaluaciones' vibroseis crew operating
in Northern Mexico, offset by the 12% increase in the average peso to dollar
exchange rate for 1994 compared to 1993.
 
     COST OF DATA ACQUISITION. Cost of data acquisition decreased 16.3% to $11.0
million in 1994 from $13.1 million in 1993 as a result of improved efficiencies
in operations of the heliportable crew which resulted in lower rental costs and
Geoevaluaciones' decision in 1994 to end subcontracting of processing services
and to perform such services itself through its arrangement with PIASA which
reduced technical assistance costs. These costs also decreased as a result of
the increase in the average peso to dollar exchange rate for 1994 compared to
1993.
 
     DEPRECIATION AND AMORTIZATION. Depreciation and amortization expenses
increased 48.3% to $1.5 million in 1994 from $1.0 million in 1993 as a result of
the acquisition of additional seismic equipment offset by the 12% increase in
the average peso to dollar exchange rate in 1994 compared to 1993.
 
                                       23
<PAGE>   26
 
     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
increased 41.7% to $1.8 million in 1994 from $1.3 million in 1993 as a result of
higher personnel costs and Geoevaluaciones' decision in 1994 to end
subcontracting of processing services and to perform such services itself
through its arrangement with PIASA, partially offset by decreases as a result of
the increase in the average peso to dollar exchange rate for 1994 compared to
1993.
 
     OPERATING INCOME. Operating income increased 51.8% to $3.4 million in 1994
from $2.2 million in 1993 as a result of improved efficiencies in the operations
of the heliportable crew and Geoevaluaciones' decision in 1994 to end
subcontracting of processing services and to perform such services itself
through its arrangement with PIASA.
 
     INTEREST EXPENSE. Interest expense decreased 54.8% to $466,000 in 1994 from
$1.0 million in 1993. The decrease in the interest expense resulted from lower
borrowing costs and a decrease in capital leases.
 
     FOREIGN CURRENCY TRANSACTION GAINS (LOSSES). Foreign currency transaction
losses were $92,000 in 1994 compared to gains of $33,000 in 1993 due to the
increase in the average peso to dollar exchange rate in 1994 compared to 1993.
 
     MISCELLANEOUS INCOME (EXPENSE). Miscellaneous income, which consists of the
interest income and miscellaneous non-operating expense line items, decreased
67.8% to $87,000 in 1994 from $270,000 in 1993. The decrease is primarily a
result of taxes (other than income taxes) related to prior years that were
refunded during 1993.
 
     INCOME TAX EXPENSE (BENEFIT). Income tax expense increased 139.2% to $1.0
million in 1994 from $418,000 in 1993 as a result of increased earnings in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     From December 31, 1995 to September 30, 1996, total assets of the Company
increased from $4.5 million to $54.4 million, total liabilities increased from
$2.7 million to $27.4 million and total stockholders' equity increased from $1.8
million to $27.0 million. These increases resulted from the Initial Public
Offering, the acquisition of the Operating Subsidiaries and new capital
expenditures partially financed by the Term Loan.
 
     On February 9, 1996, the Company completed the Initial Public Offering of
4,000,000 shares of Common Stock at a price to the public of $7.50 per share.
Subsequently, on February 21, 1996, the underwriters exercised their
over-allotment option to purchase an additional 600,000 shares at a price to the
public of $7.50 per share. The net proceeds to the Company (after deducting
underwriting discounts and commissions and offering expenses) were approximately
$28.7 million. Of this amount, approximately $3.5 million was treated, for
accounting purposes, as a dividend to the former stockholders of Geoevaluaciones
and PIASA, approximately $10.3 million was used to purchase the land seismic
assets of Northern and all of the capital stock of Kemp, approximately $4.6
million was used to repay indebtedness of the Operating Subsidiaries, $152,000
was used to retire capital leases and approximately $1.1 million was paid
subsequent to the acquisitions as a purchase price adjustment for the land-based
seismic data operations of Northern. The remaining proceeds were used primarily
for working capital and capital expenditures. See "Certain Transactions."
 
     At September 30, 1996, the Company had $1.2 million of cash. The Company's
operating activities utilized $2.1 million net cash in the nine months ended
September 30, 1996 compared with providing $1.6 million of cash in the same
period of the prior year. The reduction in net cash provided by operating
activities was primarily attributable to a net increase in working capital.
 
     Net cash used in investing activities increased to $22.5 million in the
nine months ended September 30, 1996 from $123,000 in the same period in the
prior year. This increase was due to the cash utilized to purchase Northern and
Kemp of $10.3 million and for capital expenditures of $12.3 million, offset by
cash proceeds of approximately $100,000 from the sale of equipment.
 
                                       24
<PAGE>   27
 
     Net cash provided by financing activities increased to $25.2 million in the
nine months ended September 30, 1996 from net cash utilized of $663,000 in the
comparable period in the prior year due to the completion of the Initial Public
Offering and the closing of the Loan Agreement.
 
     The Company used $12.3 million for capital expenditures in the nine months
ended September 30, 1996 compared to $123,000 in the same period of the prior
year. Simultaneously with the acquisition of the Operating Subsidiaries,
Northern and Paragon exercised options to purchase equipment which had been
rented. These capital expenditures reduced the Company's reliance on leased
equipment and improved the Company's ability to meet the demand for 3-D data
acquisition services. On May 31, 1996, the Company purchased approximately $8.5
million of equipment from Input/Output. This purchase increased the Company's
recording channel capacity from approximately 7,500 to approximately 12,000
channels.
 
     Simultaneously with the purchase of the equipment, the Company entered into
an $18 million credit facility with First Interstate Bank of Texas, N.A. The
Loan Agreement is for three years and includes $7.5 million of financing for the
above equipment and $4.5 million of refinancing of conditional sales agreements
acquired by the Operating Subsidiaries prior to the Initial Public Offering. The
new equipment has been utilized to meet the requirements of a contract with BP
Alaska, to increase the channel capacity of one of the Company's Mexican crews
for a 3-D contract with PEMEX and to increase the channel capacity of the
Company's two crews in the Rocky Mountain region.
 
     The Loan Agreement provides for the Term Loan of $15.0 million, of which
$3.0 million is available for future capital expenditures, and a revolving
credit working capital facility (the "Revolving Credit Loan") of up to $3.0
million, of which $2.0 million was available as of September 30, 1996. The Term
Loan is payable in substantially equal monthly installments through July 31,
1999, bears interest at an annual rate equal to the prime rate plus 1% (9.25% at
September 30, 1996) and is secured by a lien on the Company's accounts, accounts
receivable, equipment, machinery, fixtures, inventory, goods, chattel paper,
documents, instruments, investment property, general intangibles, and other
personal property, whether then owned or thereafter acquired, and all products
and proceeds thereof, and by guarantees by certain of the Company's
subsidiaries. The Revolving Credit Loan may be drawn down from time to time
through May 29, 1997 in an amount of up to 70% of the Company's "Eligible
Accounts" (as defined in the Loan Agreement). The rate of interest and the
security for the Revolving Credit Loan are the same as those described above for
the Term Loan. In addition to certain customary affirmative covenants, the Loan
Agreement contains restrictions on the Company with respect to (i) incurring
Debt (as defined), incurring or permitting to exist Liens (as defined) on its
property, assets or revenues, (iii) declaring or paying any dividends or other
distributions on its capital stock (or acquiring any of its capital stock), (iv)
issuing capital stock, (v) entering into transactions with affiliates, (vi)
disposing of assets, and (vii) certain other matters. The Loan Agreement also
contains financial covenants with respect to minimum tangible net worth, the
ratio of tangible net worth to net liabilities and the ratio of earnings to debt
service.
 
   
     On October 1, 1996, the Company entered into a termination agreement with
the Company's former Chief Financial Officer pursuant to which the Company
agreed to pay him $200,000 plus $5,000 per month through December 31, 1998, to
provide him with office space in the Company's New York City facility through
December 31, 1997 and to provide him with certain insurance benefits through
December 31, 1998. See "Certain Transactions."
    
 
     Since September 30, 1996, the Company has entered into short-term leases
for seismic data acquisition equipment with aggregate lease payments of
approximately $3.8 million. See note 14 of notes to the consolidated financial
statements of the Company.
 
     At November 11, 1996, the Company's estimated backlog of commitments for
services totaled approximately $42.2 million, of which approximately $2.8
million relates to a contract in Peru that is subject to the resolution of
certain uncertainties relating to obtaining required local permits. The Company
expects to complete substantially all of these commitments during 1996 and 1997;
however, commitments are subject to cancellation at the option of the Company's
customers on short notice and 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 approximately 29% of
 
                                       25
<PAGE>   28
 
the orders and commitments included in backlog at November 11, 1996 will be
completed prior to the end of 1996 and it is expected that the balance will be
completed in 1997. See "Business -- Marketing and Customers -- Backlog."
 
     The Company currently plans to continue to upgrade and expand its existing
data acquisition capabilities through the purchase of additional systems,
additional channel capacity for the six 24-bit seismic data acquisition systems
it presently owns and related vehicles and equipment. In addition, the Company
plans to repay $6.0 million of the indebtedness incurred in May 1996 under the
Loan Agreement to purchase two 24-bit seismic data acquisition systems and other
capital equipment and to acquire up to three additional I/O SYSTEM TWO(R)
seismic data acquisition systems. The Company believes that its planned capital
expenditures and operating requirements for the next 12 months will be funded
from a portion of the net proceeds of this Offering, cash from operations and,
to the extent available, borrowings under the Loan Agreement. The Company may
revise its plans in response to future changes in the oil and gas industry in
general and the demand for its services in particular, its results of
operations, its other capital requirements and other relevant factors. 3-D
Geophysical 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 other than the
proposed acquisition of J.R.S. Exploration (and certain related equipment) for
cash and shares of Common Stock (see "Business -- Proposed Acquisition of J.R.S.
Exploration"). The Company believes that, in addition to cash from operations
and borrowings under the Loan Agreement, it may fund any such acquisitions
through the issuance of additional debt or equity securities. The issuance of
additional equity securities, including shares of Common Stock, in connection
with any such acquisitions would result in additional dilution to purchasers of
Common Stock in this Offering. See "Risk Factors -- Capital Intensive Business;
Rapid Obsolescence of Technology," "Use of Proceeds" and "Business -- Capital
Expenditures."
 
IMPACT OF MEXICAN ECONOMY
 
     For the year ended December 31, 1995 and for the nine months ended
September 30, 1996, pro forma net revenues from the Mexican Operations were
26.0% and 22.7%, respectively, of pro forma net revenues of the Company. The
Company's financial performance is, and will continue to be, affected by
economic conditions in Mexico.
 
     The level of land-based seismic data acquisition services in Mexico has in
the past been vulnerable to economic downturns and changes in government
policies and public spending. Since December 1994, Mexico has experienced an
economic crisis characterized by a significant devaluation of the peso, exchange
rate instability, increased inflation, high domestic interest rates, negative
economic growth, reduced consumer purchasing power and high unemployment.
Inflation in Mexico for the year ended December 31, 1995 and for the nine months
ended September 30, 1996 was approximately 52.0% and 20.3%, respectively, based
on the consumer price index.
 
     The December 1994 devaluation of the peso has had a number of effects on
the Mexican economy that have adversely affected the financial condition of
Mexican companies, including Geoevaluaciones. The devaluation caused the peso
value of Geoevaluaciones' dollar denominated indebtedness, which consists
primarily of equipment financing, to increase significantly, and also greatly
increased the rate of inflation, resulting in a sharp rise in nominal interest
rates on peso denominated financing.
 
     The prices Geoevaluaciones pays for certain equipment, energy and other
materials are set, in part, by reference to international prices denominated in
currencies other than pesos. Pursuant to Geoevaluaciones' contracts with PEMEX,
certain of the costs incurred by Geoevaluaciones may be adjusted to take into
account economic events such as inflation and devaluation of the peso (see
"Business -- Marketing and Customers -- Contracts"). Geoevaluaciones' results of
operations, denominated in pesos, are translated into dollars for inclusion in
the Company's financial statements. However, increases in the peso to dollar
exchange rate will result in a reduction of the dollar value of peso-based
revenues of the Company as well as the dollar value of peso-based expenses of
the Company. Likewise, decreases in such rate will result in increases in the
dollar value of such revenues and expenses. As a result, such fluctuations could
have a material adverse effect on the financial condition and results of
operations of the Company. The table below sets forth the peso to
 
                                       26

dollar exchange rate during the periods indicated (based on the average of the
closing rates published by Banco Mexicano de Comercio Exterior for each business
day during such period) and the closing rate for the last day of each such

While the Company may from time to time evaluate methods to reduce foreign
exchange risks, the adoption of any particular method will depend on existing
market conditions. The Company cannot reasonably predict what method, if any, it
will adopt to reduce foreign exchange risks, and there can be no assurance that
it will adopt any such method or that, if adopted, any such method will reduce
such risks.
 
   
     The financial statements of Geoevaluaciones for the three years ended
December 31, 1995 and the nine months ended September 30, 1995 and 1996 have
been prepared using the peso as the functional currency as prescribed by
Statement of Financial Accounting Standards No. 52 ("Statement 52"). Statement
52 requires that an entity's reporting currency, which for Geoevaluaciones is
the dollar, should be used as the functional currency if inflation in the
primary economic environment exceeds 100% over a three-year period. If the
financial statements of Geoevaluaciones had been prepared using the dollar as
the functional currency for the year ended December 31, 1995 and the nine months
ended September 30, 1996, net income would have been lower.
    
 
   
     The Company believes that it is probable that the inflation rate in Mexico,
as measured by the consumer price index, will exceed 100% for the three-year
period ending December 31, 1996. Accordingly, the Company will likely adopt the
U.S. dollar as the functional currency for the Mexican Operations beginning on
January 1, 1997 in accordance with Statement of Financial Accounting Standards
No. 52. Using the U.S. dollar as the functional currency will result in an
adjustment to the consolidated statement of operations for translation gains and
losses.
    
 
FEDERAL INCOME TAXES
 
     Provisions for income taxes are based on pretax income reported for
financial statement purposes. Such provisions differ from amounts currently
payable because certain items of income and expenses are recognized for income
tax purposes in periods different from the periods for financial statement
purposes. The tax effects of these timing differences, primarily with respect to
depreciation and amortization, are reflected as deferred income taxes. The
Company's income from the Mexican Operations will be subject to the statutory
tax rate of 34% in Mexico net of applicable inflation adjustments. Any Mexican
income tax paid will be available as a credit against the Company's United
States federal income taxes upon the repatriation of any Mexican earnings to the
United States pursuant to tax treaties between Mexico and the United States.
 
IMPACT OF PRICING, INFLATION AND SEASONALITY
 
     The general availability of seismic data, equipment and crews, and the
level of exploration activity in the oil and gas industry, directly affect the
cost of acquiring seismic data. The pricing of the Company's seismic data
acquisition services is primarily a function of these factors. The Company
believes that inflationary trends had no material impact on the results of its
operations in the United States during the year ended December 31, 1995 or the
nine months ended September 30, 1996. The Mexican Operations in these periods
were affected by the inflationary pressure on the Mexican economy insofar as the
peso was devalued, the cost of peso-denominated financing rose sharply and the
Mexican government sought to curb public spending. Inflation in Mexico for the
year ended December 31, 1995 and for the nine months ended September 30, 1996
was approximately 52.0% and 20.3%, respectively, based on the consumer price
index. As a result, net
 
                                       27
<PAGE>   30
 
revenues decreased once revenues from Mexican Operations were translated from
pesos to dollars. See "Risk Factors -- Substantial Risks of Doing Business in
Latin America."
 
     The Company's seismic data acquisition operations historically have been
subject to seasonal fluctuation, with the greatest volume of data acquisition
occurring during the summer and fall. The consolidation of the Operating
Subsidiaries, the expansion into Alaska and Latin America and the proposed
expansion into Canada, if completed successfully, may enable the Company to
deploy its crews and utilize its equipment in disparate regions. The Company
will attempt to 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 the geographical diversification of
its operations may reduce the impact of seasonal fluctuations.

                                    BUSINESS
 
GENERAL
 
     3-D Geophysical, Inc. is one of the leading providers of land-based and
shallow water 3-D and 2-D seismic data acquisition services to the oil and gas
industry in the Western Hemisphere. As of October 31, 1996, the Company's nine
crews operated land-based and shallow water seismic data acquisition systems,
primarily utilizing state-of-the-art, 24-bit equipment, with a total of
approximately 12,000 channels, in Alaska, the Rocky Mountain, West Coast and
Appalachian regions and in Mexico.
 
     The seismic data acquisition services industry is currently experiencing
several significant changes, including a continuing consolidation of service
providers. The Company believes that this consolidation is due in part to the
trend by oil and gas exploration and production companies to rely on third-party
seismic contractors to provide increasingly more sophisticated and extensive 3-D
seismic surveys. These surveys require a greater number of recording channels
and therefore substantial capital expenditures. This trend is rationalizing the
seismic services industry and creating a competitive advantage for companies
with extensive 3-D channel capacity and greater financial resources.
 
     The Company believes that (i) its state-of-the-art systems, (ii) its
ability to relocate equipment and crews among the regions in which it operates,
(iii) the regional experience of its management and crews in performing 3-D and
2-D surveys, and (iv) the quality of its services and relationships with
customers will enable the Company to take advantage of this industry trend.
 
     Since the Initial Public Offering, the Company has:
 
     - Increased its channel capacity from approximately 7,500 to approximately
       12,000 channels;
 
     - Expanded its operations in Alaska with seismic data acquisition contracts
       with Arco Alaska Inc., a subsidiary of ARCO, BP Alaska and Marathon;
 
     - Obtained two of the first group of 3-D seismic data acquisition contracts
       awarded to date by PEMEX;
 
     - Established a presence in Peru by opening a branch office and a seismic
       data processing center and bidding on several contracts to provide 
       seismic data acquisition services in Peru; and
 
   
     - Entered into a stock purchase agreement to acquire J.R.S. Exploration, a
       seismic data acquisition business that has been operating in Western
       Canada since 1978 using up to four crews and utilizing 24-bit seismic 
       data acquisition systems with a total of approximately 2,000 channels.
    
 
  BUSINESS STRATEGY
 
     The Company's objective is to capitalize on the consolidation taking place
in its industry to enhance its position as one of the leading providers of
land-based and shallow water seismic data acquisition services and to become a
significant provider of related services to the oil and gas industry in the
Western Hemisphere. The Company intends to achieve this objective by:
 
     - Optimizing the utilization of its state-of-the-art seismic data
       acquisition systems by relocating equipment and crews among the regions 
       in which the Company operates;
 
     - Expanding its operations in Mexico and elsewhere in Latin America by
       seeking further contract opportunities with PEMEX and other oil companies
       operating in Latin America;
 
     - Pursuing opportunities in the United States, including Alaska, by
       attempting to strengthen existing business relationships with
       multinational companies and their affiliates, such as ARCO, BP Alaska,
       Marathon and others;
 
     - Pursuing strategic acquisitions by seeking to acquire providers of
       seismic data acquisition and related services, such as J.R.S. 
       Exploration, that complement the Company's geographic market coverage 
       and growth strategy; and
 
     - Expanding the Company's data processing and interpretation and reservoir
       characterization services already being provided to PEMEX in Mexico into
       other markets.

INDUSTRY OVERVIEW
 
     Seismic data is the principal source of information used by geoscientists
to map potential or existing oil and gas bearing formations and the geologic
structures that surround them. Seismic data is acquired over a specified area by
deploying a network of electronic cables over the area to which electronic
receivers, or geophones, are attached. Once this network is deployed, an energy
source, such as vibroseis or dynamite, is used to generate seismic waves through
a pre-determined set of frequencies that move through the rock formation under
the area and reverberate back to the surface in milliseconds. The geophones
capture the changing velocity and character of these seismic waves as they
travel down and back through the earth's surface and transmit this information a
short distance along a channel to a remote signal conditioner. The remote signal
conditioner digitizes the analog data and transmits it to a central electronics
unit that stores the acquired data. The data is then sent to a processing center
where mathematical algorithms are applied to separate signals from interference
and to correct distortion. Migration techniques are also applied to produce a
spatial representation of the subsurface formations that were surveyed. After
processing, the data is transferred to a computer workstation that allows the
data to be viewed and reconfigured by a geoscientist who interprets the data
with computer-aided exploration techniques in order to plot features and map the
structures of the subsurface area.
 
     In the past, a 2-D survey was the standard technique utilized to acquire
seismic data. 2-D seismic data can be visualized as a single vertical plane of
subsurface information. 3-D seismic surveys produce data that is best visualized
as a cube of information that can be sliced into numerous planes. Thus, 3-D
surveys provide different views of a subsurface geologic structure and much
higher resolution of the structure than is available from a 2-D survey and have
proven to be more reliable indicators of the oil and gas potential in the area
surveyed. As a result, drilling based on 3-D seismic surveys has improved the
economics of finding oil and gas. Consequently, demand for 3-D seismic surveys,
and for surveys that cover wide areas and utilize a greater number of channels,
has increased in the past several years. Furthermore, due to the enhanced
information provided, 3-D surveys have proven to be a cost effective and
efficient tool for oil and gas exploration and, increasingly, the development of
existing reserves.
 
     The oil and gas industry relies upon seismic data for the exploration of
new oil and gas reserves and for delineating the size and structure of
previously identified oil and gas fields to improve the development of those
fields. Seismic data, once acquired and processed, results in computer-generated
representations of the earth's subsurface. 2-D seismic data is collected in a
linear fashion along the surface of the earth (typically using 120 recording
channels). The acquisition of 3-D seismic data involves the use of at least 480
recording channels, allows a greater volume of seismic data to be gathered and
yields dense, 3-D grids, with a higher degree of resolution of the earth's
subsurface than a 2-D seismic survey can produce.
 
     The amount of data that can be acquired and the ability to record, process
and represent seismic data are dependent upon the type of equipment used during
the seismic data acquisition process. Seismic acquisition systems are either
traditional or distributed systems. In traditional systems, such as a DFS-V(TM)
system, signals received from the energy source are transmitted to a central
electronics unit in analog (nondigital) form with each channel requiring its own
set of wires, consequently increasing the cable weight. Traditional systems are
limited to 480 channels and are used primarily for 2-D seismic surveys. The
traditional system uses a 16-bit converter to translate signals from analog to
digital data. This technology cannot eliminate distortion of the signal that may
be caused by noise in the area or weaknesses in the signal if it is remote from
the central electronics unit.
 
     Alternatively, in a state-of-the-art distributed system, received signals
are amplified, filtered and converted into digital data by means of a 24-bit
analog-to-digital converter at remote signal conditioners before they are
transmitted to the central electronics unit on a single set of wires. Certain
distributed systems can be expanded to approximately 10,000 channels, although
the Company believes that the average distributed system currently used in the
land-based seismic data acquisition industry is significantly less than 10,000
channels. The 24-bit analog-to-digital converter extends the decibel range of
seismic recording and reduces system distortion to provide superior signal
fidelity. This technological innovation provides higher resolution data, which
is especially beneficial for 3-D surveys in geologically complex or noisy areas,
and
 
                                       30
<PAGE>   33
 
substantially reduces power consumption. Distributed systems have flexible
configuration capability and improved digital signal quality. In addition, the
lighter weight cables allow a crew to acquire greater volumes of data, as
required in 3-D surveys, over a wider area with fewer people and in less time.
Distributed systems are used primarily for 3-D surveys.
 
SEISMIC DATA ACQUISITION SERVICES
 
     The Company is engaged in land-based and shallow water seismic data
acquisition on a contract basis for its customers and not for its own account.
Seismic data acquisition projects typically begin at the time a customer
requests the Company to formulate a proposal to acquire seismic data on the
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.
 
     As of October 31, 1996, the Company operated a total of nine working
seismic crews, of which six were utilizing state-of-the-art, 24-bit seismic data
acquisition systems with a total of approximately 12,000 channels. Of the six
crews, one operates in Mexico, one in Alaska and four in the remainder of the
United States. In addition, the Company operated two crews in the United States
utilizing 16-bit seismic data acquisition systems with a total of approximately
480 channels and one crew providing drilling services in Mexico. Each crew is
either land transportable or heliportable, or both. The Company attempts to
shift entire crews and equipment from one geographic location to another in
order to capitalize on the varying seismic operating seasons in the Company's
regions of operation and to maximize the Company's efficient use of human
resources and equipment. Most of the Company's data acquisition systems, which
include remote signal conditioners, cables, geophones and central electronics
units, can be readily interchanged and relocated, depending upon the needs of
the Company's customers.
 
     A seismic crew typically consists of a supervisor, 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, if dynamite is used as the energy
source, or a vibroseis crew to operate the vibroseis trucks, if vibroseis is
used as the energy source, and an observer who operates the central electronics
unit and controls the recording of the seismic data. A fully staffed seismic
crew in the United States typically has from 10 to 25 personnel for 2-D seismic
surveys and from 20 to 60 personnel for 3-D seismic surveys, depending upon the
size and nature of the survey requested by the customer. Vehicles assigned to
each crew consist of a recording truck, two or more cable and geophone trucks, a
dynamite or vibroseis truck, several personnel vehicles with off-road capability
and, where necessary, helicopters.
 
     The Company utilizes helicopters to facilitate seismic data acquisition in
a wide range of terrains, including terrain that is inaccessible by wheeled or
tracked vehicles. The Company's experience is that helicopter use reduces the
overall cost and environmental impact of seismic data acquisition projects
through improved productivity, as crews and equipment can be more rapidly
deployed with less surface disturbance.
 
SEISMIC DATA PROCESSING AND INTERPRETATION
 
     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. PIASA and
Geoevaluaciones currently provide data processing and interpretation services to
PEMEX and the Company has opened a processing center at its branch location in
Peru. The Company intends to expand its processing and interpretation capacity
in the future and to offer such services to its customers in other geographic
regions. However, the Company has not yet developed a formal business plan to
implement this intention, and there can be no assurance that any such attempted
expansion will be successful.
 
GEOGRAPHIC AREAS OF OPERATION
 
     The Company's seismic data acquisition operations are conducted throughout
the United States (including Alaska) and in Mexico. Geoevaluaciones primarily
conducts its operations in Mexico and provides
 
                                       31
<PAGE>   34
 
   
its primary customer, PEMEX, a full complement of seismic data acquisition,
processing and interpretation services and reservoir characterization. The
Company has established a presence in Peru by opening a branch office and a
seismic data processing center and bidding on several contracts to provide
seismic data acquisition services in Peru. In addition, the Company is seeking
to expand its operations into Canada and has entered into a stock purchase
agreement to acquire J.R.S. Exploration, a Calgary-based provider of land-based
seismic data acquisition services (see "-- Proposed Acquisition of J.R.S.
Exploration").

CAPITAL EXPENDITURES
 
     There are many competitors in the land-based seismic data acquisition
business and substantial financial and other resources are required to maintain
the state-of-the-art technology necessary to permit effective competition in
bidding for contracts. Seismic data acquisition technology has progressed
rapidly over recent years and the Company expects this trend to continue. The
cost of sophisticated seismic data acquisition equipment and related crew
training has increased significantly over the last several years. The cost of
equipping a crew with a state-of-the-art system, such as an I/O SYSTEM TWO(R)
(including training and ancillary equipment), can range from approximately $3.0
to $10.0 million, the largest component of which is attributable to the channel
boxes. The Company's strategy is to update its data acquisition systems as often
as necessary to maintain its competitive position. To do so, however, may
require large expenditures of capital in addition to the Company's planned
capital expenditures. There can be no assurance that the Company will have the
capital necessary to upgrade its equipment to maintain its competitive position
or to acquire any additional required equipment, or that any required financing
therefor will be available on favorable terms. Furthermore, the Company may
require additional capital expenditures in the event that the level of its
operations increases significantly. If the Company is unable to raise the
capital necessary to update or increase the capacity of its data acquisition
systems to the extent necessary, it will be unable to update such systems or
increase its level of operations and may be materially and adversely affected as
a result.
 
     The Company's current plan is to expand significantly its data acquisition
systems after the consummation of this Offering. Specifically, the Company
intends to increase its channel capacity by up to 5,000 channels through the
purchase of additional systems and equipment, including a 1,000 channel seismic
data acquisition system currently being rented from The Andrews Group
International, Inc. (see "Use of Proceeds" and "Certain Transactions") and the
purchase of equipment currently being rented and used in the
 
                                       32
<PAGE>   35
 
Rocky Mountain region. The Company anticipates that the funds for such
expenditures will come from a portion of the net proceeds of this Offering (see
"Use of Proceeds") and cash from operations. The Company may revise its plans in
response to future changes in the oil and gas industry in general and the demand
for its services in particular, its results of operations, its other capital
requirements and other relevant factors. See "Risk Factors -- Capital Intensive
Business; Rapid Obsolescence of Technology," "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and "-- Competition."

     The Company's crews often conduct operations in extreme weather, in
difficult terrain that is not easily accessible and under other hazardous
conditions. Accordingly, the Company's operations are subject to risks of injury
to personnel and loss of equipment. Fixed costs, including costs associated with
operating leases, labor costs and depreciation, account for more than half of
the Company's costs and expenses. 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. For example, no insurance is available
at a cost deemed reasonable by the Company for war, nationalization,
appropriation or other extreme events.
 
     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 United States. The consolidation of
the Operating Subsidiaries and the expansion into Latin America has enabled the
Company to deploy its crews and utilize its equipment in disparate regions. As a
result, the Company expects to conduct its 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 widening
the geographical scope of its operations, the impact of seasonal fluctuations
may be reduced.
 
MARKETING AND CUSTOMERS
 
     Marketing. Since the Initial Public Offering, the Company has continued
marketing to existing customers on a regional basis in order to preserve these
long-term relationships. The Company has established a corporate marketing
center in Englewood, Colorado, which is responsible for (i) coordinating
marketing and communication activities, (ii) expanding the Company's marketing
to integrated and multinational oil and gas companies, and (iii) standardizing
and coordinating the submission of bids.
 
     Contracts. The Company provides its services to customers pursuant to
contracts 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 of the Company's contracts result from competitive bidding. 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 availability, technological expertise and reputation
for dependability and safety.
 
     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 a turnkey contract, 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 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 turnkey and term contract is used, the risk of
business interruption is shared in an agreed percentage by the
 
                                       33
<PAGE>   36
 
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.
 
     Geoevaluaciones' contracts are procured from a bidding process that is
regulated by Mexican law. PEMEX, as a government-owned company, prepares
specifications of projects for which seismic-related services are required. All
potential bidders that meet certain technical, legal and other requirements
submit bids which must include seismic data acquisition, processing and
interpretation services. Geoevaluaciones and PIASA submit a single bid for their
combined services. PEMEX places no restrictions on the participation of
foreign-owned companies in the bidding process. Geoevaluaciones' contracts with
PEMEX contain price terms which are fixed at the time the contracts are signed
and in the past have been denominated in pesos. These contracts contain cost
adjustment provisions which are triggered upon the occurrence of certain
economic events such as a devaluation of the peso, a change in the rate of
inflation or an increase in the statutory minimum wage rate. The adjustments may
be requested by Geoevaluaciones, but only with respect to the direct costs
incurred by Geoevaluaciones under a contract that are affected by the economic
event. While these adjustment features protect Geoevaluaciones against partial
declines in its peso-denominated profit margin, they do not protect
Geoevaluaciones from a decline in the dollar value of its profits or net assets.
See "Risk Factors -- Substantial Risks of Doing Business in Latin America" and
note 2 to the financial statements of Geoevaluaciones.
 
     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.
 
     Customers. The Company's customers include and have included a number of
major oil companies and their affiliates, including PEMEX, ARCO, BP Alaska and
Marathon, as well as many smaller, independent oil and gas companies. In the
year ended December 31, 1995 and the nine months ended September 30, 1996, the
Company's net revenues attributable to PEMEX were approximately $9.8 million and
$9.1 million, or 26.0% and 22.7%, respectively, of the Company's pro forma net
revenues in those periods. In the year ended December 31, 1995, Duncan Oil, Inc.
accounted for $4.3 million, or 11.4%, of the Company's pro forma net revenues.
In the nine months ended September 30, 1996, Seitel, Inc. and BP Alaska
accounted for $5.9 million, or 14.8%, and $6.5 million, or 16.3%, of the
Company's pro forma net revenues, respectively. No other single customer
accounted for more than 10% of the pro forma net revenues in those periods. The
loss of PEMEX as a customer would have a material adverse effect on the
Company's financial condition and results of operations.
 
     A large portion of the Company's net revenues 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. Each of the Operating
Subsidiaries has a number of customers for which, over the years, services have
been repeatedly provided.
 
     Safety and Environmental Program. Certain of the Company's customers,
including PEMEX and other large oil and gas companies, 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. The Company
employs a full-time safety officer who is in charge of implementing a
Company-wide health, safety and environmental program intended to comply with
the requirements of major oil and gas companies and applicable regulatory
authorities.
 
   
     Backlog. At November 30, 1996, the Company's backlog of data acquisition
surveys was approximately $42.6 million. Approximately 61% of the backlog was
attributable to the Company's operations in the United States, and approximately
39% of such backlog related to the operations in Mexico and Peru. The majority
of such backlog consisted of written orders or commitments; however, contracts
for services are occasionally varied or modified by mutual consent and, in many
instances, are subject to cancellation by the customer on short notice without
penalty. In addition, a contract in Peru for $2.8 million is subject to the
resolution of certain uncertainties relating to obtaining required local
permits. 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
approximately 29% of the orders and
    
 
                                       34
<PAGE>   37
 
   
commitments included in backlog at November 30, 1996 will be completed prior to
the end of 1996 and it is expected that the balance will be completed in 1997.
    
 
COMPETITION
 
     The Company has extensive competition in each of the regions in which it
operates. Contracts for seismic data acquisition services generally are awarded
on the basis of price, crew experience, equipment availability, technological
expertise and reputation for dependability and safety. Competition is
particularly intense for providers of more technologically advanced seismic
data. Certain of the Company's major competitors have more crews and operate
data acquisition systems having significantly more channels than the Company,
provide integrated data acquisition, processing and interpretation services and
have far greater financial and other resources than the Company and more
extensive relationships with major integrated and multinational oil and gas
companies. These 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 competitors for contracts to conduct seismic surveys.
See "Risk Factors -- Dependence Upon Energy Industry Spending," "Risk
Factors -- Capital Intensive Business; Rapid Obsolescence of Technology" and
"Risk Factors -- Substantial Competition."
 
EMPLOYEES
 
     As of November 15, 1996, the Company employed approximately 1,284 people,
of whom 16 performed management and marketing functions, 52 performed
administrative services or clerical functions, 160 were geophysicists or
rendered engineering or other technical services and approximately 1,056 were
members of the Company's seismic crews or performed other functions. None of the
Company's employees is represented by a labor union or is a direct or indirect
party to a collective bargaining agreement. The Company believes it has good
relations with its employees.
 
PROPERTIES
 
     The Company occupies 13 leased and two owned facilities. The owned
facilities are both located in Ohio and are utilized by Paragon to house its
administrative and maintenance operations. Of the 13 leased facilities, 4 are
located in Mexico, 2 are located in each of Colorado and Texas and 1 is located
in each of Alaska, New York, Peru, North Dakota and Ohio. These properties are
utilized for administration, maintenance and storage and range in size from
approximately 2,000 to approximately 26,000 square feet. The terms of the leases
range from month-to-month to leases that expire in 2002 and provide for annual
rents ranging from approximately $7,200 to approximately $165,000. The Company's
annual lease expense under these leases totals approximately $470,000.
Approximately 60% of the Company's New York City offices is utilized by persons
unrelated to the Company. Mr. Joel Friedman, the Chairman of the Board of
Directors of the Company, has agreed to reimburse the Company for any amounts
under the New York City lease (which provides for an aggregate annual rental of
$165,000) that are payable with respect to space that is not utilized by the
Company and which have not been paid by sub-lessees (see
"Management -- Employment Agreements; Non-Competition Agreements" and "Certain
Transactions").
 
     The Company believes that its facilities are adequate for its present and
reasonably foreseeable needs.
 
LEGAL PROCEEDINGS
 
     The Company is a defendant in or party to a number of lawsuits arising in
the ordinary course of its business, which lawsuits the Company believes have
little substantive merit. While the outcome of these lawsuits cannot be
predicted with certainty, the Company does not believe that any of these
lawsuits will have a material adverse effect on its operations or financial
position.

     Geoevaluaciones has a dispute, and may be threatened with litigation, in
connection with certain agreements it entered into with Capilano International
Inc., a Canadian company ("Capilano"). The dispute concerns a certain Letter of
Intent and a Technical Assistance Agreement, dated June 3, 1991 and June 1,
1992, respectively (the "Capilano Agreements"). Capilano stated in its 1994
Annual Report to Shareholders that it has had difficulty in collecting amounts
owing from a Mexican company (presumably, Geoevaluaciones) to which Capilano
supplied technical assistance and stated in its 1995 Annual Report that it had
written down by approximately C$1.9 million accounts receivable in Mexico.
Geoevaluaciones maintains that it is not obligated to compensate Capilano for
certain services Geoevaluaciones believes were either inadequately provided or
not provided at all by Capilano. Representatives of Capilano and Geoevaluaciones
have had ongoing discussions since May 1996 in an effort to resolve this
dispute. The Company currently is not able to estimate the effect, if any, on
its results of operations and financial position which may result from the
resolution of this matter. Therefore, the financial statements of the Company do
not reflect any adjustments related to this matter. A portion of the amounts
payable to the former stockholders of Geoevaluaciones in connection with the
acquisition by 3-D Geophysical of the stock of Geoevaluaciones owned by such
stockholders is held in escrow and available to pay amounts in settlement or
otherwise in connection with the dispute with Capilano. See "Certain
Transactions."
 
REGULATION
 
     Seismic data acquisition operations are subject to various laws and
regulations in the United States, Mexico, Peru and Canada, as well as other
countries in which the Company may operate in the future. 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.
 
PROPOSED ACQUISITION OF J.R.S. EXPLORATION
 
   
     On December 10, 1996, the Company entered into a stock purchase agreement
(the "Stock Purchase Agreement") pursuant to which it agreed to purchase J.R.S.
Exploration, a land-based seismic data acquisition business headquartered in
Calgary, Alberta, Canada. J.R.S. Exploration has been operating in Western
Canada since 1978 using up to four seismic crews utilizing 24-bit seismic
recording systems manufactured by Sercel that have a total of approximately
2,000 channels. J.R.S. Exploration's two principal customers accounted in the
aggregate for over 50% of J.R.S. Exploration's revenues in its fiscal year ended
November 30, 1995. J.R.S. Exploration is currently a party to seismic data
acquisition services contracts with these two customers which expire on June 30,
1997 and September 30, 1998. For its fiscal year ended November 30, 1995, J.R.S.
Exploration had revenues of approximately C$11.0 million and earnings before
interest, taxes and depreciation of approximately C$2.3 million. As of December
11, 1996, the exchange rate was approximately $.73 per Canadian dollar.
    
 
   
     If the acquisition is consummated, the Company will seek to expand J.R.S.
Exploration's business during winter, the peak Canadian operating season, by
shifting certain of the Company's equipment to Canada during the period from
January through April, and the Company believes that it will be able to utilize
J.R.S. Exploration's equipment in the United States (including Alaska) during
the other months of the year.
    
 
   
     Under the terms of the Stock Purchase Agreement, the Company will acquire
all of the issued and outstanding shares of capital stock of the intermediate
holding companies that own all of the issued and outstanding capital stock of
J.R.S. Exploration for C$3.5 million in cash and a number of shares of Common
Stock having a value of approximately C$3.4 million in the aggregate. In
addition the Company will repay approximately C$1.8 million of debt J.R.S.
Exploration owes to a commercial bank. Also under the terms of the Stock
Purchase Agreement, on or before the closing thereunder, Messrs. Donald Janveau
and W. Garnet Mueller, the principal stockholders and executive officers of
J.R.S. Exploration, will enter into three-year employment agreements (the
"Employment Agreements") with J.R.S. Exploration pursuant to which
    
 
                                       36
<PAGE>   39
 
   
Mr. Janveau will serve as President and Chief Executive Officer of J.R.S.
Exploration and Mr. Mueller will serve as Vice President of Operations of J.R.S.
Exploration. The Employment Agreements each provide for an annual salary of
C$150,000. The Employment Agreements also each contain a five-year covenant not
to compete with the Company or any of its subsidiaries in the provision of
seismic data acquisition or analysis services or any services related thereto.
In connection with the acquisition of J.R.S. Exploration, the Company also
proposes to acquire all of the issued and outstanding capital stock of Siegfried
& Siegfried Resource Consultants, Ltd. ("Siegfried & Siegfried"), an Alberta
corporation that is wholly-owned by an employee of J.R.S. Exploration and owns
certain seismic data acquisition equipment presently being leased to J.R.S.
Exploration. The proposed purchase price for Siegfried & Siegfried is C$150,000
in cash and a number of shares of Common Stock having a value of C$150,000 in
the aggregate.
    
 
   
     In connection with the acquisition of Siegfried & Siegfried, J.R.S.
Exploration will enter into a three-year employment agreement with David
Siegfried, pursuant to which Mr. Siegfried will serve as Sales Manager and
Operations Supervisor of J.R.S. Exploration for an annual salary of C$100,000.
Upon the closing of the acquisition of Siegfried & Siegfried, the Company will
grant to Mr. Siegfried a ten-year option to purchase 15,000 shares of Common
Stock at the closing price for such stock on the Nasdaq National Market on that
day. The option, which will be granted under the Plan, will be exercisable in
four equal cumulative installments commencing one year after the date of grant.
The consummation of the acquisitions, which is expected to occur in January
1997, is subject to customary conditions.
    
 
   
     There can be no assurance that the Company will consummate the acquisitions
of J.R.S. Exploration and Siegfried & Siegfried. Pursuant to an agreement with
the Company, J.D. White will provide certain advice and assistance to the
Company in connection with the proposed acquisitions. See "Certain
Transactions." The Company also has engaged one of the representatives of the
underwriters of this Offering to act as its exclusive financial advisor in
connection with the proposed acquisition of J.R.S. Exploration. See
"Underwriting."

DIRECTOR COMPENSATION
 
     Each member of the Board who is not an employee of the Company receives:
(i) an annual retainer of $10,000; (ii) $750 per meeting of the Board of
Directors or any committee thereof at which such Director is present in person;
and (iii) reimbursement of all ordinary and necessary expenses incurred in
attending any meeting of the Board of Directors or committee thereof. Directors
who are full-time employees of the Company do not receive any compensation for
serving as directors. Any newly elected or appointed non-employee director
automatically receives a nonqualified option under the Plan to purchase 10,000
shares of Common Stock at an exercise price equal to the fair market value of
the Common Stock on the date of grant. Such option vests in cumulative
installments of one-third on each of the first, second and third anniversaries
of the date of grant and expire on the tenth anniversary of the date of such
grant.
 
   
     On February 9, 1996, non-employee directors (Messrs. Andrews, Bahna,
Brandrup, Emil and O'Brien) were awarded nonqualified stock options to purchase
10,000 shares of Common Stock pursuant to the Plan. The exercise price of these
options was equal to the price to the public in the Initial Public Offering of
$7.50 per share. Upon joining the Board in April 1996, Mr. Tavella was granted
an option under the Plan to purchase 10,000 shares of Common Stock at an
exercise price of $12.3125 per share. On September 30, 1996, each non-employee
director (Messrs. Andrews, Bahna, Brandrup, Emil, O'Brien and Tavella) was
granted a nonqualified ten year option to purchase 6,667 shares of Common Stock
at an exercise price of $8.50 per share, subject to the approval of the
Company's stockholders at the next annual stockholders' meeting. These options,
which were not granted pursuant to the Plan, vest in full on February 6, 1997,
subject to the approval of the Company's stockholders at the next annual
stockholders' meeting.
    
 
EXECUTIVE COMPENSATION
 
     3-D Geophysical was incorporated in March 1995 and conducted no operations
until February 1996, when it consummated the Initial Public Offering and
acquired the Operating Subsidiaries and PIASA. No salaries were paid during 1995
by 3-D Geophysical. Compensation to be paid to the Company's chief executive
officer and the four other most highly compensated executive officers during
1996 is disclosed below (see "Management -- Employment Agreements;
Non-Competition Agreements" and "Management --
 
                                       41

Long-Term Incentive Compensation Plan"). The Board has not adopted a bonus plan,
but anticipates that it will adopt and implement a performance-based cash bonus
plan in 1997.
 
EMPLOYMENT AGREEMENTS; NON-COMPETITION AGREEMENTS
 
     Each of Messrs. Friedman, Davis, Widynowski, Ferran, Koons, Kemp and
Merchant has entered into an employment agreement with the Company that expires
on December 31, 1998, except for the agreement with Mr. Koons, which expires on
September 30, 1999, and for the agreement with Mr. Ferran, which expires on
December 31, 2000. The employment agreements provide for base annual salaries as
follows: Mr. Friedman: $125,000 plus an annual office allowance of $75,000, a
portion of which is being applied to payments under the Company's New York City
lease (see "Business -- Properties"); Mr. Davis: $155,000; Mr. Widynowski:
$140,000; Mr. Ferran: $140,000; Mr. Koons: $125,000; Mr. Kemp: $75,000; and Mr.
Merchant: $82,500. Certain of the Company's executive officers are entitled to
an automobile allowance, and, in addition, each executive officer who has
entered into an employment agreement will be eligible pursuant to his employment
agreement for a bonus to be determined in the discretion of the Board or a
committee thereof.
 
     Each of the employment agreements with Messrs. Friedman, Ferran, Koons and
Kemp contains a covenant not to compete during the employee's employment with
the Company or its subsidiaries and for one year thereafter unless the Company
terminates the employee's employment without cause. Each of the agreements with
Messrs. Davis, Merchant and Widynowski contains a similar covenant not to
compete but provides that upon termination of the agreement, other than by the
Company for cause (as defined in the agreement) or by the employee without good
reason (as defined in the agreement), the employee's covenant not to compete
will lapse unless the Company pays the employee 80% of the employee's base
salary in the year following such termination. These employment agreements and
covenants not to compete were entered into in the ordinary course of business.
Mr. Davis' agreement also provides that upon termination under certain
circumstances he will receive a payment for certain relocation expenses and the
continuation of certain benefits for a one-year period. Mr. Kemp receives a
monthly payment of $4,167 for 36 months, ending in January 1999, in
consideration of the covenant not to compete contained in his employment
agreement. With the exception of Mr. Kemp's agreement, the employment agreements
entered into with the Company's executive officers do not provide for any
separate payment to be made with respect to the covenants not to compete during
the term of the agreements. In addition, in connection with the acquisition by
3-D Geophysical of Geoevaluaciones, Mr. Ferran and the other former stockholders
of Geoevaluaciones entered into the Geoevaluaciones Non-Competition Agreement
(defined below) under which Mr. Ferran and such former stockholders were
entitled to certain additional consideration (see "Certain Transactions").
 
     Until September 30, 1996, Mr. White served as the Company's Executive Vice
President and Chief Financial Officer under an employment agreement that was to
expire on December 31, 1998 and provided for a base salary of $150,000. Upon his
resignation as an officer of the Company, Mr. White and the Company entered into
an agreement terminating this employment agreement (see "Certain Transactions").
 
LONG-TERM INCENTIVE COMPENSATION PLAN
 
     The purpose of the Plan is to provide directors, officers, and other key
employees and consultants of the Company and its subsidiaries with additional
incentives by providing them with the opportunity to increase their ownership
interests in the Company. The maximum number of shares of Common Stock that may
be subject to awards granted under the Plan is 720,000 shares, which may be
authorized and unissued shares, treasury shares or shares acquired by the
Company for purposes of the Plan. Shares of Common Stock which are attributable
to awards which have expired, terminated or been cancelled or forfeited during
any calendar year, in addition to shares in respect of which a stock
appreciation right ("SAR") is settled for cash or shares tendered in payment
upon the exercise of an option or SAR, are available for issuance or use in
connection with future awards. In the event of a stock split, stock dividend,
recapitalization or the like, the Stock Option Committee will equitably adjust
the number of shares available under the Plan and subject to outstanding awards
and the exercise prices of outstanding awards.
 
     Awards under the Plan are granted by a Committee of the Board of Directors
appointed for that purpose (the "Stock Option Committee") and may include: (i)
options to purchase shares of Common Stock,
 
                                       42
<PAGE>   45
 
including incentive stock options ("ISOs"), nonqualified stock options or both;
(ii) SARs, whether in conjunction with the grant of stock options or independent
of such grant; and (iii) restricted stock. To the extent necessary to comply
with Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
and Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), awards granted under the Plan are not assignable or
transferable except by the laws of descent and distribution.
 
     The Stock Option Committee consists of two or more directors who qualify as
disinterested persons under Rule 16b-3 under the Exchange Act. Subject to the
terms of the Plan, the Stock Option Committee has the authority, among other
things, to: (i) select the persons entitled to receive awards under the Plan;
(ii) determine the form of awards; (iii) determine the number of shares of
Common Stock covered by an award; and (iv) determine the terms and conditions of
awards, including any restrictions or limitations on transfer, any vesting
schedules or the acceleration thereof and any forfeiture provisions or waivers
thereof. The exercise price of stock options is determined by the Stock Option
Committee subject to the requirement that the exercise price of an ISO cannot be
less than the fair market value of the shares of Common Stock covered by such
grant at the time of grant. The option exercise price is payable in cash, or,
with the consent of the Stock Option Committee, by surrender of shares of Common
Stock held at least six months by the optionee and having a fair market value on
the date of the exercise equal to part or all of the option exercise price, or
by such other payment method as the Stock Option Committee may prescribe. The
exercise price of options granted to non-employee directors under the Plan may
be payable, at the discretion of the non-employee director, in cash or by
surrender of shares of Common Stock held at least six months by such
non-employee director.
 
     All options and SARs not yet exercised shall terminate upon termination of
the grantee's employment for cause. Unless the Stock Option Committee otherwise
specifies: (i) if a grantee's employment terminates for reasons other than
cause, disability or death, the grantee's options or SARs or both generally will
remain exercisable for three months after termination to the extent that they
were exercisable at termination, but will not be exercisable after the scheduled
expiration date of the award; and (ii) if a grantee's employment terminates by
reason of disability, the grantee's options or SARs or both generally will
remain exercisable for one year after termination to the extent that they were
exercisable at termination, but will not be exercisable after the scheduled
expiration date of the award. If a grantee's employment terminates for any
reason, the Company generally will have the right to require forfeiture of
restricted shares in exchange for any amount paid by the grantee for such
shares.
 
     Unless sooner terminated by the Board of Directors, the authority to grant
awards under the Plan will terminate on the tenth anniversary of its adoption.
All awards made under the Plan prior to its termination will remain in effect
until they are satisfied or terminated. The Board of Directors may, without
stockholder approval, suspend, discontinue, revise or amend the Plan at any time
or from time to time; provided, however, that stockholder approval must be
obtained for any amendment for which such approval is required by Rule 16-3
promulgated under the Exchange Act, to the extent that the Board of Directors
believes it is appropriate to qualify under Rule 16b-3. The Stock Option
Committee may make certain amendments to outstanding awards, including any
amendments that change or waive the Plan provisions applicable at employment
termination.
 
     The grant of an option or SAR will create no tax consequences for the
grantee or the Company. A grantee will not have taxable income upon exercising
an ISO (except that the alternative minimum tax may apply) and the Company will
receive no deduction at that time. Upon exercising an option other than an ISO,
the participant must generally recognize ordinary income equal to the difference
between the exercise price and fair market value of the stock acquired on the
date of exercise, and, upon exercising an SAR, the participant must generally
recognize ordinary income equal to the cash (or the fair market value of the
stock) received. In each case, the Company will be entitled to a deduction equal
to the amount recognized as ordinary income by the grantee. An award of
restricted shares of Common Stock will not result in taxable income to the
grantee or in a tax deduction for the Company until such time as the shares are
no longer subject to forfeiture (unless the grantee elects an earlier date). At
that time, the grantee generally will recognize ordinary income equal to the
fair market value of the shares less any amount paid for them, and the Company
generally will be entitled to a
 
                                       43
<PAGE>   46
 
tax deduction in the same amount. Dividends paid on forfeitable restricted
shares are treated as compensation for federal income tax purposes.
 
     A grantee's disposition of shares acquired under the Plan generally will
result in short-term or long-term capital gain or loss measured by the
difference between the sale price and the participant's tax basis in such shares
(or the exercise price of the option in the case of shares acquired by exercise
of an ISO and held until a date at least two years after grant and one year
after exercise). Generally, there will be no tax consequences to the Company in
connection with a disposition of shares acquired under an option or other award,
except that the Company will be entitled to a deduction (and the grantee will
recognize ordinary taxable income) if shares acquired upon exercise of an ISO
are disposed of before the applicable ISO holding periods have been satisfied.
 
     Section 162(m) to the Code generally disallows a public company's tax
deduction for compensation to the chief executive officer or any of the four
other most highly compensated executive officers in excess of $1 million in any
tax year. Compensation that qualifies as "performance-based compensation" is
excluded from the $1 million deductibility cap, and therefore remains fully
deductible by the company that pays it. The Company expects that options granted
with an exercise price at least equal to 100% of fair market value of the
underlying stock at the date of grant, and any restricted stock award
conditioned upon achievement of performance goals, will qualify as such
"performance-based compensation," although other awards under the Plan may not
so qualify. However, there can be no assurance that any awards under the Plan
will qualify as "performance-based compensation" that is fully deductible by the
Company under Section 162(m) of the Code.
 
     The Plan also provides for automatic option grants to directors who are not
otherwise employed by the Company or its subsidiaries. See "-- Director
Compensation."
 
     The Stock Option Committee has granted pursuant to the Plan options to
purchase an aggregate of 385,000 shares of Common Stock to executive officers of
the Company in the amounts and on the terms described below:

Each of the options vests in cumulative installments of one-third of the number
of shares subject thereto on each of the first three anniversaries of the grant
date and expires on the tenth anniversary of the date of grant. In addition, the
Stock Option Committee granted pursuant to the Plan options to purchase an
aggregate of 179,350 shares of Common Stock to other key employees of the
Company at prices ranging from $7.375 to $12.3125 per share. Each of these
options vests in cumulative installments of one-fourth of the number of shares
subject thereto on each of the first four anniversaries of the grant date and
expires in 2006.
 
     On April 26, 1996 the Stock Option Committee granted nonqualified options
to each of Messrs. Friedman, Davis and Widynowski to purchase 75,000 shares of
Common Stock. These options, which were not granted under the Plan, have an
exercise price of $12.3125 per share, were granted on the same terms and
conditions as are provided for in the Plan, vest in cumulative installments of
18,750 shares on each of the first four anniversaries of the date of grant and
expire ten years after the date of grant.

    ownership; and (b) 250,000 shares of Common Stock issuable upon exercise of
    a stock option granted under the Plan (see "Management -- Long-Term
    Incentive Compensation Plan"). Includes 57,394 shares of Common Stock, all
    of which shares are held in trust by a Mexican bank for Mr. Ferran's
    benefit.
 
(5) Excludes 30,000 shares of Common Stock issuable upon exercise of a stock

                              CERTAIN TRANSACTIONS
 
     Simultaneously with the consummation of the Initial Public Offering, 3-D
Geophysical acquired in separate transactions, in exchange for cash, notes and
shares of Common Stock, the Operating Subsidiaries and PIASA, as described
below. Of the approximately $28.7 million of net proceeds to the Company from
the Initial Public Offering, (i) approximately $13.8 million was used to pay the
cash portion of the purchase price to certain former stockholders of the
Operating Subsidiaries and PIASA; and (ii) approximately $5.9 million was used
to repay indebtedness of the Operating Subsidiaries, including approximately
$1.9 million of indebtedness that was guaranteed by or was owed to certain
former stockholders of the Operating Subsidiaries. In addition, the former
stockholders of the Operating Subsidiaries and PIASA received an aggregate of
1,599,319 shares of Common Stock having a market value, based on the price to
the public in the Initial Public Offering of $7.50 per share, of approximately
$12.0 million in the aggregate.
 
     Under a stock purchase agreement (the "Geoevaluaciones Stock Purchase
Agreement"), 3-D Geophysical purchased from Mr. Ferran, his wife, his
father-in-law and his mother-in-law (collectively, the "Former Geoevaluaciones
Stockholders") all of the issued and outstanding shares of capital stock of
Geoevaluaciones. In connection with this acquisition, 3-D Geophysical entered
into a separate non-competition agreement with each of the Former
Geoevaluaciones Stockholders (collectively, the "Geoevaluaciones Non-Competition
Agreement"). The Geoevaluaciones Stock Purchase Agreement and the
Geoevaluaciones Non-Competition Agreement were entered into on the basis of
arm's-length negotiations among the Former Geoevaluaciones Stockholders and, on
behalf of 3-D Geophysical, Messrs. Friedman and White. Neither 3-D Geophysical
nor the Former Geoevaluaciones Stockholders obtained an appraisal of
Geoevaluaciones or such non-competition covenants in connection with this
transaction; at September 30, 1995, the net book value of Geoevaluaciones was
approximately $2.1 million. Pursuant to the Geoevaluaciones Stock Purchase
Agreement, 3-D Geophysical paid to the Former Geoevaluaciones Stockholders: (i)
$2.45 million in cash at closing; and (ii) $1.0 million by delivery at closing
of four promissory notes, payable in installments at six, 12, 18 and 24 months
after the closing in the following aggregate amounts (which amounts include
interest at 8% per annum): $290,000, $280,000, $270,000 and $260,000,
respectively. Pursuant to the Geoevaluaciones Non-Competition Agreement, 3-D
Geophysical paid to the Former Geoevaluaciones Stockholders: (i) 100,000 shares
of Common Stock that was issued at closing to trusts with Mexican banks for the
benefit of the Former Geoevaluaciones Stockholders, and is to be released
February 9, 1998; and (ii) $1.9 million, reduced by the amount of any
liabilities Geoevaluaciones had not disclosed to the Company and by any amount
paid by Geoevaluaciones to settle or otherwise in connection with
Geoevaluaciones' dispute with a supplier (see "Business -- Legal Proceedings"),
such portion of the consideration consisting of (a) $1.0 million in cash that
was deposited at the closing in a bank account, and which, subject to any such
reduction, may be disbursed only upon the approval of (1) either Mr. Ferran or
another Former Geoevaluaciones Stockholder, and (2) either Mr. Friedman or Mr.
White; and (b) 117,647 shares of Common Stock that were delivered at closing to
trusts with Mexican banks for the benefit of the Former Geoevaluaciones
Stockholders, and which may not be
 
                                       46
<PAGE>   49
 
released until June 30, 1997 and then only upon the approval of a designated
representative of the Former Geoevaluaciones Stockholders and Mr. Friedman. Mr.
Ferran entered into an employment agreement with the Company and serves as
Executive Vice President -- Latin American Operations, President of
Geoevaluaciones and a Director of the Company. In addition, Mr. Ferran may
receive, pursuant to the Geoevaluaciones Non-Competition Agreement, as described
above, up to a maximum of 57,394 of the shares of Common Stock payable to the
Former Geoevaluaciones Stockholders. Of the amounts paid by the Company to the
Former Geoevaluaciones Stockholders, Mr. Ferran received, as described above,
$645,167 in cash, a note in the principal amount of $263,333, with interest of
8% per annum thereon payable over two years, and will receive up to $263,334 in
cash that may not be released until June 30, 1997 (see "Management -- Employment
Agreements; Non-Competition Agreements" and "Security Ownership of Management
and Principal Stockholders").
 
     Under a stock purchase agreement, 3-D Geophysical purchased from Robert P.
Andrews, Luis H. Ferran and five other stockholders of PIASA all of the issued
and outstanding shares of capital stock of PIASA for approximately $300,000,
consisting of $60,000 in cash and approximately 28,235 shares of Common Stock.
The stock purchase agreement with the former stockholders of PIASA was entered
into on the basis of arm's-length negotiations among Mr. Andrews, the President
and Chairman of the Board of PIASA, and Mr. Ferran, a director and Secretary of
PIASA, on behalf of the former stockholders of PIASA, and Messrs. Friedman and
White, on behalf of 3-D Geophysical. Neither 3-D Geophysical nor PIASA obtained
an appraisal of PIASA in connection with this transaction; at September 30,
1995, the net book value of PIASA was approximately $288,000. Mr. Ferran
received 9,176 shares of Common Stock and $19,500 in connection with the sale of
PIASA, and Mr. Andrews received 10,588 shares of Common Stock and $22,500 in
connection with the sale of PIASA.
 
     Although the acquisitions of Geoevaluaciones and PIASA were made on an
arm's-length basis, Mr. Ferran was the holder of 77% of the outstanding shares
of Common Stock prior to the acquisitions and for accounting purposes the
acquisitions of Geoevaluaciones and PIASA have been treated as a
recapitalization of Geoevaluaciones and PIASA with Geoevaluaciones (combined
with PIASA) as the acquiror of 3-D Geophysical.
 
     Under an asset purchase agreement between Northern's predecessor ("Old
Northern") and 3-D Geophysical, 3-D Geophysical purchased substantially all of
Old Northern's assets related to its land-based seismic data acquisition
business. Neither 3-D Geophysical nor Old Northern obtained an appraisal of the
assets of Old Northern to be acquired by 3-D Geophysical in connection with this
transaction; at September 30, 1995, the net book value of such assets was
approximately $2.0 million. Such asset purchase agreement was the result of
arm's-length negotiations among representatives of 3-D Geophysical and
representatives of Old Northern. The aggregate consideration paid by the Company
was $10.9 million in cash. Wayne P. Widynowski, the Vice President of Marketing
of Old Northern, entered into an employment agreement with the Company and
serves as Executive Vice President and Chief Operating Officer of the Company
and as President of Northern (see "Management -- Employment Agreements;
Non-Competition Agreements," and "Security Ownership of Management and Principal
Stockholders").
 
     Under a merger agreement among Paragon, 3-D Geophysical and a subsidiary of
3-D Geophysical, Paragon merged with the subsidiary with Paragon being the
surviving entity (the "Paragon Merger"). Mr. Friedman, two other individuals and
members of their respective immediate families (the "Former Paragon
Stockholders") each owned one-third of the issued and outstanding capital stock
of Paragon. In August 1994, Paragon purchased all of the net assets of Paragon
Geophysical, Inc., an Ohio corporation, for $1.1 million in cash and, in
addition, assumed long-term liabilities of $1.9 million. To finance the
purchase, Paragon borrowed $1.1 million from a commercial bank that was
guaranteed by the Former Paragon Stockholders and the Former Paragon
Stockholders contributed approximately $150,000 in cash. The Former Paragon
Stockholders received approximately 1,314,261 shares of Common Stock in
connection with the Paragon Merger. In addition, the Company assumed an
aggregate of $4.8 million of Paragon's debt, of which $1.7 million had been
personally guaranteed by Mr. Friedman and certain other Former Paragon
Stockholders. All of this debt was repaid upon consummation of the Initial
Public Offering with a portion of the net proceeds therefrom. The terms of the
Paragon Merger were not determined through arm's-length negotiations
 
                                       47
<PAGE>   50
 
and may have been significantly greater than would have resulted from
arm's-length negotiations. The Company did not obtain an appraisal of Paragon in
connection with the Paragon Merger; at September 30, 1995, the net book value of
Paragon was negative by approximately $496,000. Mr. Friedman, who, prior to the
Paragon Merger, was the President and Chief Executive Officer of 3-D Geophysical
and Chairman of the Board and Chief Executive Officer of Paragon, together with
members of his family, owns a total of 438,159 shares of Common Stock as a
result of the Paragon Merger. Mr. White, who, prior to the Paragon Merger, was
acting Chief Financial Officer of Paragon, served as Executive Vice President,
Chief Financial Officer, Secretary, Treasurer and a Director of 3-D Geophysical
until September 30, 1996 and currently serves as a Director of and financial
advisor to the Company. Mr. Merchant, who serves as Vice President of the
Company and President of Paragon, owns 13,588 shares of Common Stock as a
founder of 3-D Geophysical. In connection with the Paragon Merger, Messrs.
Friedman, White and Merchant entered into employment agreements. Mr. White
entered into a termination agreement with the Company following his resignation
in September 1996 (see "Management -- Employment Agreements; Non-Competition
Agreements," "Security Ownership of Management and Principal Stockholders" and
"Certain Transactions").
 
     Under a stock purchase agreement among G.C.L. Kemp and his wife (the
"Former Kemp Stockholders") and 3-D Geophysical (the "Kemp Stock Purchase
Agreement"), 3-D Geophysical purchased all of the issued and outstanding shares
of capital stock of Kemp. The Kemp Stock Purchase Agreement was entered into on
the basis of arm's-length negotiations among G.C.L. Kemp, on behalf of the
Former Kemp Stockholders, and Messrs. Friedman and White, on behalf of 3-D
Geophysical, and the consideration payable to the Former Kemp Stockholders
thereunder represents the value the Former Kemp Stockholders deemed appropriate
for their business. Neither the Company nor the Former Kemp Stockholders
obtained an appraisal of Kemp in connection with this transaction; at September
30, 1995 the net book value of Kemp was $422,000. The aggregate consideration
paid by the Company to the Former Kemp Stockholders, as modified by amendments
in June 1996, was approximately $919,000, consisting of $625,000 in cash and
$294,000 paid by delivery of 39,176 shares of Common Stock. In addition, the
Company assumed and repaid approximately $152,000 in debt owed by Kemp, of which
$135,000 was guaranteed by Mr. Kemp. In addition, the Company assumed $50,000 of
debt owed by Kemp to Mr. Kemp, of which $25,000 was forgiven by Mr. Kemp in June
1996. Mr. Kemp entered into an employment agreement pursuant to which he serves
as a Vice President of the Company. Mr. Davis entered into an employment
agreement with the Company, pursuant to which he serves as President, Chief
Executive Officer and a Director of the Company. Mr. Davis was appointed as
President of Kemp by the Board of Directors in June 1996.
 
     In connection with its formation in March 1995, 3-D Geophysical issued
1,400,681 shares of Common Stock to the founding stockholders, including
1,084,346 shares to Mr. Ferran, 160,342 shares to Mr. White, 103,271 shares to
Mr. Andrews, 13,588 shares to each of Messrs. Davis and Merchant, 8,153 shares
to Mr. Kemp and 4,620 shares to each of Messrs. Bahna and Brandrup. The amounts
paid by each of these stockholders for the foregoing shares are as follows: Mr.
Ferran -- $399; Mr. White -- $59; Mr. Andrews -- $38; Messrs. Davis and
Merchant -- $5; Mr. Kemp -- $3; Messrs. Bahna and Brandrup -- $1.70. The
founding stockholders (including the individuals named in the preceding
sentence) paid an aggregate of $515 for the foregoing shares. Based on the price
to the public in the Initial Public Offering of $7.50 per share, such number of
shares owned by the founding stockholders had a market value immediately
following the consummation of the Initial Public Offering of $8.1 million in the
case of Mr. Ferran, $1.2 million in the case of Mr. White, $775,000 in the case
of Mr. Andrews, $102,000 in the case of each of Messrs. Davis and Merchant,
$61,000 in the case of Mr. Kemp and $35,000 in the case of each of Messrs. Bahna
and Brandrup.
 
   
     Mr. Andrews is the sole stockholder of The Andrews Group International,
Inc. ("Andrews Group") which, through its Mexican affiliate, A.G.I. Mexicana,
S.A. de C.V. (collectively, the "Andrews Companies"), acts as the exclusive
representative for several companies in Mexico, including Input/Output and
Landmark Graphics Corporation. Geoevaluaciones and PIASA purchase goods and
services from A.G.I. Mexicana and during the nine months ended September 30,
1996 such purchases totalled approximately $464,000. In addition, as of
September 30, 1996 PIASA owed A.G.I. Mexicana $115,000 for goods and services
purchased prior to the Initial Public Offering. The Company also leases
approximately 1,000 channels of 3-D seismic data acquisition equipment and
geophones from Andrews Group under two separate six-month lease agreements with
automatic monthly renewals thereafter that provide for deposits of approximately
    
 
                                       48
<PAGE>   51
 
$293,000 and $77,000, respectively, and for monthly payments of approximately
$110,000 and $29,000, respectively. The leases provide the Company with options
to purchase the equipment for approximately $2,445,000 and $642,000,
respectively, subject to offsets of 80% of the rental payments during the six
months ending March 1, 1997 and a 10% discount if the options are exercised
during such period. The Company intends to use a portion of the proceeds of this
Offering to purchase the equipment (see "Use of Proceeds" and
"Business -- Customers and Contracts"). The Company anticipates that it will
continue to purchase goods and services from the Andrews Companies. The Company
believes that the past transactions with the Andrews Companies have been, and
that any future transactions with the Andrews Companies will be, on terms no
less favorable to the Company than could be obtained from an unaffiliated third
party.
 
   
     The Company agreed to pay to a consulting company owned by Mr. White
$250,000 for financial advisory and other consulting services in connection with
the structuring, negotiation and consummation of the acquisitions of the
Operating Subsidiaries and PIASA, of which $125,000 was paid upon the
consummation of the Initial Public Offering and $125,000 is payable on January
3, 1997. In connection with Mr. White's resignation as an executive officer of
the Company and the termination of his employment agreement on October 1, 1996,
the Company agreed to pay Mr. White $200,000 plus $5,000 per month through
December 31, 1998, the expiration date of the employment agreement, to provide
him with office space in the Company's New York City facility through December
31, 1997, provided he does not serve as an officer of a competitor of the
Company during that period, and to provide him with certain insurance benefits
through December 31, 1998. In exchange therefor, Mr. White has agreed to render
financial and advisory services to the Company in connection with this Offering
and the proposed acquisition of J.R.S. Exploration.
    
 
     The Company leases space in New York City at an annual base rental of
$165,000 to provide offices for Messrs. Friedman and White. Mr. Friedman has
agreed to reimburse the Company for any amounts under the lease that are payable
with respect to space that is not utilized by the Company and which have not
been paid by sub-lessees (see "Business -- Properties").
 
     In the future, transactions with affiliates of the Company are anticipated
to be minimal. Any such transaction will be approved by a majority of the Board
of Directors, including a majority of the disinterested members of the Board of
Directors, and will be made on terms no less favorable to the Company than could
be obtained from an unaffiliated third party.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     3-D Geophysical's Certificate of Incorporation provides for authorized
capital stock of 25,000,000 shares of Common Stock, par value $.01 per share, of
which 11,900,000 shares will be issued and outstanding upon completion of this
Offering, and 1,000,000 shares of Preferred Stock, $.01 par value per share
("Preferred Stock"), of which no shares will be outstanding upon completion of
this Offering.
 
COMMON STOCK
 
     As of the date hereof, 7,600,000 shares of Common Stock are issued and
outstanding. All of the issued and outstanding shares of Common Stock are, and
the shares of Common Stock offered hereby, when issued in this Offering, will
be, validly issued, fully paid and nonassessable.
 
     The holders of Common Stock are entitled to one vote for each share on all
matters voted on by stockholders, and, except as otherwise required by law or as
provided in any resolution adopted by the Board of Directors with respect to any
series of Preferred Stock (as defined below), the holders of shares of Common
Stock exclusively possess all voting power.
 
     The Certificate of Incorporation and By-laws provide that the Board of
Directors will be divided into three classes of directors, with the classes to
be as nearly equal in number as possible (see "Management -- Directors and
Executive Officers").
 
     Subject to any preferential rights of any outstanding series of Preferred
Stock created by the Board of Directors from time to time, the holders of Common
Stock are entitled to such dividends as may be declared from time to time by the
Board of Directors from funds available therefor, and upon liquidation will be
entitled
 
                                       49
<PAGE>   52
 
to receive pro rata all assets of the Company available for distribution to such
holders. The Common Stock is not convertible or redeemable and there are no
sinking fund provisions therefor. Holders of the Common Stock are not entitled
to any preemptive rights.
 
     As of November 15, 1996, there were 73 holders of record of Common Stock.
 
PREFERRED STOCK
 
     The Board of Directors of the Company, without any action by the
stockholders of the Company, is authorized to issue up to 1,000,000 shares of
Preferred Stock, in one or more series and to determine the voting rights
(including the right to vote as a series on particular matters), preferences as
to dividends and in liquidation and the conversion and other rights of each such
series. There are no shares of Preferred Stock outstanding. See "-- Certain
Anti-Takeover Effects of Certain Provisions of the Certificate of Incorporation,
By-laws and Delaware General Corporation Law."
 
CERTAIN ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE CERTIFICATE OF
INCORPORATION, BY-LAWS AND DELAWARE GENERAL CORPORATION LAW
 
     The Certificate of Incorporation and By-laws contain a number of provisions
that could make more difficult the acquisition of the Company by means of a
tender or exchange offer, a proxy contest or otherwise. The description of such
provisions set forth below is intended only as a summary and is qualified in its
entirety by reference to the pertinent sections of the Certificate of
Incorporation and the By-laws, forms of which are filed as exhibits to the
Registration Statement of which this Prospectus forms a part.
 
     Classified Board of Directors; Removal of Directors. The classification of
directors will have the effect of making it more difficult for stockholders to
change the composition of the Board of Directors. At least two annual meetings
of stockholders generally will be required to effect a change in a majority of
the Board of Directors. Such a delay may help ensure that the Company's
directors, if confronted by a stockholder attempting to force a proxy contest, a
tender or exchange offer or an extraordinary corporate transaction, would have
sufficient time to review the proposal as well as any available alternatives to
the proposal and to act in what they believe to be the best interest of the
stockholders. The classification provisions will apply to every election of
directors, however, regardless of whether a change in the composition of the
Board of Directors would be beneficial to the Company and its stockholders and
whether a majority of the Company's stockholders believes that such a change
would be desirable.
 
     The Certificate of Incorporation provides that directors of the Company may
only be removed for cause by the affirmative vote of the holders of 80% of the
voting power of all of the then outstanding shares of stock entitled to vote
generally in the election of directors (the "Voting Stock").
 
     The classification provisions could also have the effect of discouraging a
third party from initiating a proxy contest, making a tender or exchange offer
or otherwise attempting to obtain control of the Company, even though such an
attempt might be beneficial to the Company and its stockholders. These
provisions could thus increase the likelihood that incumbent directors will
retain their positions. In addition, the classification provisions may
discourage accumulations of large blocks of the Common Stock by purchasers whose
objective is to take control of the Company and remove a majority of the Board
of Directors, and thus could tend to reduce the likelihood of fluctuations in
the market price of the Common Stock that might result from accumulations of
large blocks for such purpose. Accordingly, stockholders could be deprived of
certain opportunities to sell their shares of Common Stock at a higher market
price than might otherwise be the case.
 
     Preferred Stock. The Certificate of Incorporation authorizes the Board of
Directors to establish one or more series of Preferred Stock and to determine,
with respect to any series of Preferred Stock, the terms and rights of such
series, including (i) the designation of the series, (ii) the number of shares
of the series, which number the Board may thereafter (except where otherwise
provided in the certificate of designation) increase or decrease (but not below
the number of shares thereof then outstanding), (iii) whether dividends, if any,
will be cumulative or noncumulative and the dividend rate of the series, (iv)
the dates at which dividends, if any, will be payable, (v) the redemption rights
and price or prices, if any, for shares of the series, (vi) the
 
                                       50
<PAGE>   53
 
terms and amounts of any sinking fund provided for the purchase or redemption of
shares of the series, (vii) the amounts payable on shares of the series in the
event of any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, (viii) whether the shares of the series will be
convertible into shares of any other class or series, or any other security, of
the Company or any other corporation, and, if so, the specification of such
other class or series or such other security, the conversion price or prices or
rate or rates, any adjustments thereof, the date or dates as of which such
shares shall be convertible and all other terms and conditions upon which such
conversion may be made, (ix) restrictions, if any, on the issuance of shares of
the same series or of any other class or series, and (x) the voting rights, if
any, of the stockholders of such series, which may include the right of such
stockholders to vote separately as a class on any matter.
 
     The Company believes that the ability of the Board of Directors to issue
one or more series of Preferred Stock will provide the Company with flexibility
in structuring possible future financing and acquisitions and in meeting other
corporate needs which might arise. The authorized shares of Preferred Stock, as
well as shares of Common Stock, will be available for issuance without further
action by the Company's stockholders, unless such action is required by
applicable law or the rules of any stock exchange or automated quotation system
on which the Company's securities may be listed or traded.
 
     Although the Board of Directors has no intention at the present time of
doing so, it could issue a series of Preferred Stock that could, depending on
the terms of such series, impede the completion of a merger, tender offer or
other takeover attempt. The Board of Directors will make any determination to
issue such shares based on its judgment as to the best interests of the Company
and its stockholders. The Board of Directors, in so acting, could issue
Preferred Stock having terms that could discourage an acquisition attempt
through which an acquiror may be otherwise able to change the composition of the
Board of Directors, including a tender or exchange offer or other transaction
that some, or a majority, of the Company's stockholders might believe to be in
their best interests or in which stockholders might receive a premium for their
stock over the then current market price of such stock.
 
     No Stockholder Action by Written Consent; Special Meetings. The Certificate
of Incorporation provides that, subject to the rights of any holders of
Preferred Stock to elect additional directors under specified circumstances,
stockholder action can be taken only at an annual or special meeting of
stockholders and prohibit stockholder action by written consent in lieu of a
meeting. The Certificate of Incorporation and the By-laws provide that special
meetings of stockholders can be called only upon a written request stating the
purpose of such meeting delivered to the Chairman of the Board, the President or
the Secretary, and signed by a majority of the Board of Directors or by
resolution of the Board or the Executive Committee thereof. Stockholders are not
permitted to call a special meeting or to require that the Board call a special
meeting. Moreover, the business permitted to be conducted at any special meeting
of stockholders is limited to the business brought before the meeting pursuant
to the notice of meeting given by the Company.
 
     The provisions of the Certificate of Incorporation and the By-laws
prohibiting stockholder action by written consent may have the effect of
delaying consideration of a stockholder proposal, including a stockholder
proposal that a majority of the stockholders believes to be in the best interest
of the Company, until the next annual meeting unless a special meeting is called
at the request of a majority of the Board of Directors or by resolution of the
Board or the Executive Committee thereof. These provisions would also prevent
the holders of a majority of the Voting Stock from unilaterally using the
written consent procedure to take stockholder action. Moreover, a stockholder
could not force stockholder consideration of a proposal over the opposition of
the Board by calling a special meeting of stockholders prior to the time a
majority of the Board believes such consideration to be appropriate.
 
     Amendment of Certain Provisions of the Certificate of Incorporation and
By-laws. Under the Delaware General Corporation Law (the "DGCL"), the
stockholders have the right to adopt, amend or repeal the By-laws and, with the
approval of the Board of Directors, the Certificate of Incorporation. The
Certificate of Incorporation provides that the affirmative vote of the holders
of at least 80% of the voting power of the then outstanding shares of Voting
Stock, voting together as a single class, and in addition to any other vote
required by the Certificate of Incorporation or By-laws, is required to amend
provisions of the Certificate of
 
                                       51
<PAGE>   54
 
Incorporation or By-laws relating to: (i) the prohibition of stockholder action
without a meeting; (ii) the prohibition of stockholders calling a special
meeting; (iii) the number, election and term of the Company's directors; or (iv)
the removal of directors. The vote of the holders of a majority of the voting
power of the then outstanding shares of Voting Stock is required to amend all
other provisions of the Certificate of Incorporation. The Certificate of
Incorporation further provides that the By-laws may be amended by the Board of
Directors or by the affirmative vote of the holders of at least a majority of
the voting power of the then outstanding shares of Voting Stock, voting together
as a single class. These super-majority voting requirements will have the effect
of making more difficult any amendment by stockholders of the By-laws or of any
of the provisions of the Certificate of Incorporation described above, even if a
majority of the Company's stockholders believes that such amendment would be in
their best interests.
 
     Anti-Takeover Legislation. Section 203 of the DGCL provides that, subject
to certain exceptions specified therein, a corporation shall not engage in any
business combination with any "interested stockholder" for a three-year period
following the date that such stockholder becomes an interested stockholder
unless (i) prior to such date, the board of directors of the corporation
approved either the business combination or the transaction which resulted in
the stockholder becoming an interested stockholder, (ii) upon consummation of
the transaction which resulted in the stockholder becoming an interested
stockholder, the interested stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced (excluding
certain shares), or (iii) on or subsequent to such date, the business
combination is approved by the board of directors of the corporation and at an
annual or special meeting of stockholders by the affirmative vote of a least
two-thirds of the outstanding voting stock which is not owned by the interested
stockholder. Section 203 of the DGCL provides that, except as specified, an
interested stockholder is defined to include (x) any person that is the owner of
15% or more of the outstanding voting stock of the corporation, or is an
affiliate or associate of the corporation and was the owner of 15% or more of
the outstanding voting stock of the corporation at any time within three years
immediately prior to the relevant date, and (y) the affiliates and associates of
any such person.
 
     Under certain circumstances, Section 203 of the DGCL makes it more
difficult for a person who would be an "interested stockholder" to effect
various business combinations with a corporation for a three-year period,
although the stockholders may elect to exclude a corporation from the
restrictions imposed thereunder. The Certificate of Incorporation does not
exclude the Company from the restrictions imposed under Section 203 of the DGCL.
The provisions of Section 203 of the DGCL may encourage companies interested in
acquiring the Company to negotiate in advance with the Board of Directors of the
Company, since the stockholder approval requirement would be avoided if a
majority of the directors then in office approve, prior to the time the
stockholder becomes an interested stockholder, either the business combination
or the transaction which results in the stockholder becoming an interested
stockholder.
 
LIMITATION ON DIRECTORS' LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Certificate of Incorporation and By-laws each contain a provision that
eliminates, to the extent currently allowed under the DGCL, the personal
monetary liability of a director to the Company and its stockholders for breach
of his fiduciary duty of care as a director. If a director were to breach the
duty of care in performing his duties as a director, neither the Company nor its
stockholders could recover monetary damages from the director, and the only
course of action available to the Company's stockholders would be equitable
remedies, such as an action to enjoin or rescind a transaction involving a
breach of the fiduciary duty of care. To the extent certain claims against
directors are limited to equitable remedies, this provision of the Certificate
of Incorporation may reduce the likelihood of derivative litigation and may
discourage stockholders or management from initiating litigation against
directors for breach of their duty of care. Additionally, equitable remedies may
not be effective in many situations. If a stockholder's only remedy is to enjoin
the completion of the Board of Directors' action, this remedy would be
ineffective if the stockholder does not become aware of a transaction or event
until after it has been completed. In such a situation, such stockholder would
have no effective remedy against the directors. Liability for monetary damages
remains for (i) any breach of the duty of loyalty to the Company or its
stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) payment of an
improper dividend or
 
                                       52
<PAGE>   55
 
improper repurchase or redemption of the Company's stock under Section 174 of
the DGCL or (iv) any transaction from which the director derived an improper
personal benefit. The Certificate of Incorporation further provides that in the
event the DGCL is amended to allow the further elimination or limitation of the
liability of directors, then the liability of the Company's directors shall be
limited to the fullest extent permitted by the amended DGCL. The DGCL permits a
corporation to indemnify certain persons, including officers and directors, who
are (or are threatened to be made) parties to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of their being officers or directors of the corporation. The indemnity
may include expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by an indemnified officer or
director, provided he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the corporation's best interests and, in the case of
criminal proceedings, provided he had no reasonable cause to believe that his
conduct was unlawful. The By-laws provide indemnification to the fullest extent
allowed pursuant to the foregoing provisions of the DGCL.
 
     The DGCL further permits a corporation to indemnify certain persons,
including officers and directors, who are (or are threatened to be made) parties
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of their being officers
or directors of the corporation. The indemnity may include expenses (including
attorneys' fees) actually and reasonably incurred by the indemnified officer or
director, provided he acted in good faith and in a manner he reasonably believed
to be in, or not opposed to, the corporation's best interests. However, no such
person will be indemnified as to matters for which he is found to be liable for
negligence or misconduct in the performance of his duty to the corporation
unless, and only to the extent that, indemnification is ordered by a court. The
Certificate of Incorporation and By-laws provide indemnification of the
Company's directors and officers to the fullest extent allowed pursuant to the
foregoing provisions of the DGCL.
 
     Delaware corporations also are authorized to obtain insurance to protect
officers and directors from certain liabilities, including liabilities against
which the corporation cannot indemnify its directors and officers. The Company
intends to obtain a directors' and officers' liability insurance policy prior to
the closing of this Offering.
 
     All of the foregoing indemnification provisions include statements that
such provisions are not to be deemed exclusive of any other right to indemnity
to which a director or officer may be entitled under any by-law, agreement, vote
of stockholders or disinterested directors or otherwise.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is American
Securities Transfer, Incorporated.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this Offering, the Company will have outstanding
11,900,000 shares of Common Stock. The 4,300,000 shares to be sold in this
Offering (plus any additional shares sold upon exercise of the Underwriters'
over-allotment option) will be, and the 4,600,000 shares sold in the Initial
Public Offering are, freely tradeable in the public market without restriction
or further registration under the Securities Act, except for any shares
purchased by "affiliates" of the Company, as that term is defined in Rule 144.
The remaining 3,000,000 outstanding shares of Common Stock (the "Restricted
Shares") which were issued in connection with the formation of 3-D Geophysical
and the acquisitions of the Operating Subsidiaries and PIASA are deemed to be
"restricted securities" within the meaning of Rule 144 and may be publicly
resold only if registered under the Securities Act or sold in accordance with an
eligible exemption from registration, such as Rule 144. Of the Restricted
Shares, 1,400,681 shares will be eligible for resale in the public market
commencing in March 1997 and 1,599,319 shares will be eligible in February 1998,
subject in each case to certain volume and other restrictions under Rule 144.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are required to be aggregated), including an affiliate of the
Company, who beneficially owns "restricted securities" acquired
 
                                       53
<PAGE>   56
 
from the Company or an affiliate of the Company at least two years prior to the
sale is entitled to sell within any three-month period a number of shares that
does not exceed the greater of (i) one percent of the then outstanding shares of
Common Stock (119,000 shares based on the number of shares outstanding
immediately after completion of this Offering, assuming no exercise of the
Underwriters' over-allotment option), and (ii) the average weekly reported
trading volume of the Common Stock during the four calendar weeks immediately
preceding the date on which notice of such sale is filed with the SEC, provided
certain manner of sale and notice requirements and requirements as to the
availability of current public information concerning the Company are satisfied.
Under Rule 144(k), a person who has not been an affiliate of the Company for a
period of three months preceding a sale of securities by him, and who
beneficially owns such "restricted securities" acquired from the Company or an
affiliate of the Company at least three years prior to such sale, would be
entitled to sell such shares without regard to volume limitations, manner of
sale provisions, notification requirements or requirements as to the
availability of current public information concerning the Company. Shares held
by persons who are deemed to be affiliates of the Company, including any shares
acquired by affiliates in this Offering, are subject to such volume limitations,
manner of sale provisions, notification requirements and requirements as to
availability of current public information concerning the Company, regardless of
how long the shares have been owned or how they were acquired, and, in addition,
the sale of any "restricted securities" beneficially owned by affiliates is
subject to the two-year holding period requirement. As defined in Rule 144, an
"affiliate" of an issuer is a person that directly or indirectly through the use
of one or more intermediaries controls, or is controlled by, or is under common
control with, such issuer.
 
     The Company and its officers and directors have agreed that for a period of
120 days from the date of this Prospectus they will not without the prior
written consent of Smith Barney Inc. (i) sell, offer to sell, solicit an offer
to buy, contract to sell or otherwise transfer or dispose of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for, or any rights to purchase or acquire, shares of Common Stock, or (ii) grant
any options or warrants to purchase shares of Common Stock (other than the grant
of options under the Plan and Common Stock issuable upon the exercise of options
granted under the Plan or otherwise to officers, directors and other key
employees of the Company).
 
   
     The Company has outstanding options to purchase an aggregate of 889,352
shares of Common Stock (see "Management -- Director Compensation" and
"Management -- Long-Term Incentive Compensation Plan"), of which options to
purchase approximately 215,000 shares become exercisable in February 1997
(approximately 40,000 of which are subject to stockholder approval at the next
annual stockholders' meeting), options to purchase approximately 70,000 shares
become exercisable in April 1997, options to purchase 4,450 shares become
exercisable in August 1997 and options to purchase 10,000 shares become
exercisable in September 1997. The Company intends to register under the
Securities Act the shares issuable upon exercise of options granted under the
Plan and otherwise and, upon such registration, such shares will be eligible for
resale in the public market, except that any such shares issued to affiliates
are subject to the volume limitations and other restrictions of Rule 144.
    
 
     No prediction can be made as to the effect, if any, that the sale of shares
or the availability of shares for sale will have on the market price of the
Common Stock prevailing from time to time. Nevertheless, sales of substantial
amounts of the Common Stock in the public market could adversely affect
prevailing market prices and the ability of the Company to raise equity capital
in the future. See "Underwriting."

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to approval of certain legal matters by counsel and
to certain other conditions. The Underwriters are obligated to take and pay for
all of shares of Common Stock offered hereby (other than those covered by the
over-allotment option described below) if any such shares are taken.
 
     The Underwriters, for whom Smith Barney Inc., Rauscher Pierce Refsnes, Inc.
and Simmons & Company International are acting as representatives (collectively,
the "Representatives"), propose to offer part of the shares of Common Stock
directly to the public at the public offering price set forth on the cover page
of this Prospectus and part of the shares of Common Stock to certain dealers at
a price which represents a concession not in excess of $          per share
under the public offering price. The Underwriters may allow, and such dealers
may reallow, a concession not in excess of $          per share to certain other
dealers. After the initial offering of the shares to the public, the public
offering price and such concessions may be changed by the Representatives.
 
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to 645,000 additional
shares of Common Stock at the price to public set forth on the cover page of
this Prospectus, less the underwriting discounts and commissions. The
Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, in connection with this Offering. To the extent such
option is exercised, each Underwriter will be obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number of shares set forth opposite each Underwriter's name in the
preceding table bears to the total number of shares listed in such table.
 
     By letter agreement dated November 14, 1996, the Company engaged Rauscher
Pierce Refsnes, Inc. ("Rauscher Pierce"), one of the Representatives, to act as
its exclusive financial advisor in connection with the Company's proposed
acquisition of J.R.S. Exploration. Pursuant to the letter agreement, the Company
has agreed to pay Rauscher Pierce a $100,000 transaction fee upon the closing of
the acquisition and to reimburse Rauscher Pierce for up to $15,000 for
out-of-pocket expenses incurred in connection with such services.
 
     The Company and its officers and directors have agreed that for a period of
120 days from the date of this Prospectus they will not without the prior
written consent of Smith Barney Inc. (i) sell, offer to sell, solicit an offer
to buy, contract to sell or otherwise transfer or dispose of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for, or any rights to purchase or acquire, shares of Common Stock, or (ii) grant
any options or warrants to purchase shares of Common Stock (other than the grant
of
 
                                       55

options under the Plan and Common Stock issuable upon the exercise of options
granted under the Plan or otherwise to officers, directors and other key
employees of the Company).
 
     Certain of the Underwriters and selling group members that currently act as
market makers for the Common Stock may engage in "passive market making" in the
Common Stock on the Nasdaq National Market in accordance with Rule 10b-6A under
the Exchange Act. Rule 10b-6A permits, upon the satisfaction of certain
conditions, underwriters and selling group members participating in a
distribution that are also Nasdaq market makers in the security being
distributed to engage in limited market making transactions during the period
when Rule 10b-6 under the Exchange Act would otherwise prohibit such activity.
Rule 10b-6A prohibits underwriters and selling group members engaged in passive
market making generally from entering a bid or effecting a purchase at a price
that exceeds the highest bid for those securities reported on the Nasdaq
National Market by a market maker that is not participating in the distribution.
Under Rule 10b-6A, each underwriter or selling group member engaged in passive
market making is subject to a daily net purchase limitation equal to 30% of such
entity's average daily trading volume during the two full consecutive calendar
months immediately preceding the date of the filing of the registration
statement under the Securities Act pertaining to the security to be distributed.
 
     The Company and the Underwriters have agreed to indemnify each other
against certain liabilities, including liabilities under the Securities Act.

                             3-D GEOPHYSICAL, INC.
 
                  PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
     The following pro forma consolidated financial statements of 3-D
Geophysical, Inc. (the "Company") include the pro forma consolidated balance
sheet as of September 30, 1996 and the pro forma consolidated statement of
operations for the year ended December 31, 1995 and the nine months ended
September 30, 1995 and 1996.
 
     On February 9, 1996, simultaneously with the consummation of the Company's
Initial Public Offering (the "Initial Public Offering"), the Company acquired in
separate transactions, in exchange for cash, notes and shares of Common Stock,
Geoevaluaciones, PIASA, Northern's land-based seismic data operations, Paragon
and Kemp. See "Certain Transactions." For accounting purposes, the acquisitions
of Geoevaluaciones and PIASA were treated as a recapitalization of
Geoevaluaciones and PIASA with Geoevaluaciones (combined with PIASA) as the
acquiror and predecessor of 3-D Geophysical. Accordingly, the combined net
assets of Geoevaluaciones and PIASA were valued at historical cost and the
consideration given to the former stockholders of Geoevaluaciones and PIASA was
treated for accounting purposes as a dividend. The acquisitions of Northern's
land-based seismic data operations, Paragon and Kemp (the "U.S. Operating
Subsidiaries") were treated as business combinations accounted for by the
purchase method of accounting as prescribed by Accounting Principles Board
Opinion No. 16 and Staff Accounting Bulletin No. 48 (as applied prior to the
issuance of SAB 97) and are included within the Company's historical
consolidated statement of operations commencing February 9, 1996. The
acquisition of Paragon's common stock in exchange for shares of Common Stock was
accounted for at Paragon's historical cost. Northern's land-based seismic data
operations and Kemp were valued at the fair market value of consideration given.
In connection with the acquisitions of Northern's land-based seismic data
operations and Kemp, the excess of consideration given over the fair market
value of net assets is being amortized on a straight-line basis over 15 years.
 
   
     On December 10, 1996, the Company entered into a stock purchase agreement
pursuant to which it agreed to purchase J.R.S. Exploration Company Limited
("J.R.S. Exploration") (see "Business -- Proposed Acquisition of J.R.S.
Exploration"). The consummation of the acquisition is subject to customary
conditions. The proposed acquisition of J.R.S. Exploration and certain related
equipment is being treated as a probable business combination which will be
accounted for by the purchase method of accounting as prescribed by Accounting
Principles Board Opinion No. 16. The excess of consideration being offered over
the fair market value of the net assets acquired is recorded in the following
pro forma consolidated financial statements as goodwill and is being amortized
on a straight-line basis over 15 years.
    
 
     The pro forma consolidated balance sheet as of September 30, 1996 gives
effect to the acquisition of J.R.S. Exploration and certain related equipment as
if such transaction had occurred on September 30, 1996. The pro forma
consolidated statements of operations for the year ended December 31, 1995 and
the nine months ended September 30, 1995 and 1996 assume the Company had
completed the recapitalization, the acquisition of the U.S. Operating
Subsidiaries, the Initial Public Offering and the acquisition of J.R.S.
Exploration and certain related equipment on January 1, 1995.
 
     The pro forma consolidated financial statements have been derived from: (i)
the audited statement of operations of Geoevaluaciones (as predecessor of the
Company) for the year ended December 31, 1995 appearing elsewhere in this
Prospectus; (ii) the unaudited interim consolidated financial statements of the
Company as of and for the nine months ended September 30, 1996 and 1995
appearing elsewhere in this Prospectus; (iii) the audited statements of
operations for Northern's land-based seismic data operations and Paragon for the
nine months ended September 30, 1995 are included elsewhere in this Prospectus;
(iv) the unaudited statement of operations of Kemp for the nine months ended
September 30, 1995 and for the year ended December 31, 1995 not included in this
Prospectus; (v) the unaudited statement of operations of Northern's land-based
seismic data operations and Paragon for the year ended December 31, 1995
appearing elsewhere in this Prospectus; (vi) the unaudited interim statements of
operations of Northern's land-based seismic data operations, Paragon and Kemp
for the period from January 1, 1996 through February 8, 1996 not

included in this Prospectus; and (vii) the U.S. dollar financial statements of
J.R.S. Exploration as of and for the nine months ended August 31, 1996, for the
year ended November 30, 1995 and the nine months ended August 31, 1995 not
included in this Prospectus. The Canadian dollar J.R.S. Exploration financial
statements, appearing elsewhere in this Prospectus, have been translated into
U.S. dollars using the current rate method (i.e., assets and liabilities were
translated at the August 31, 1996 exchange rate and revenues and expenses have
been translated at the appropriate average exchange rate for the period). The
translation is not included in this Prospectus. The J.R.S. Exploration financial
statements include all adjustments necessary to conform to U.S. Generally
Accepted Accounting Principles ("GAAP"). The principal difference between U.S.
and Canadian GAAP is accounting for income taxes. This difference, as it relates
to J.R.S. Exploration, does not produce a material difference and therefore no
adjustment has been made.
 
     The following sets forth the rates (in U.S. dollars) used to translate the
J.R.S. Exploration financial statements.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
3-D Geophysical, Inc. and Subsidiaries:
 
     We have audited the accompanying combined balance sheet of 3-D Geophysical,
Inc. and Subsidiaries, (the "Predecessor Company" as defined in Note 1) as of
December 31, 1995 and 1994, and the related combined statements of operations,
changes in stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1995. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these combined 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.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of 3-D
Geophysical, Inc. and Subsidiaries (as defined in Note 1) as of December 31,
1995 and 1994 and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1995 in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     On February 9, 1996, 3-D Geophysical, Inc. ("Company") consummated an
initial public offering (the "Initial Public Offering") and simultaneously
acquired in separate transactions, in exchange for cash, notes and shares of
Common Stock, Geoevaluaciones, S.A. de C.V. ("Geoevaluaciones"), certain assets
and liabilities of the land-based seismic data operations of Northern
Geophysical of America, Inc. ("Northern"), Paragon Geophysical, Inc. ("Paragon")
and Kemp Geophysical Corporation ("Kemp") (collectively referred to as the
"Operating Subsidiaries") and Procesos Interactivos Avanzados, S.A. de C.V.
("PIASA"),
 
     For accounting purposes the acquisitions of Geoevaluaciones and PIASA have
been treated as a recapitalization of Geoevaluaciones and PIASA with
Geoevaluaciones (combined with PIASA) deemed to be the acquiror of the Company
and considered the predecessor company. For purposes of identification and
description, the Company is referred to as the "Predecessor" for the period
prior to the Initial Public Offering and the acquisition of the Operating
Subsidiaries and PIASA as described below, the "Successor" for the period
subsequent to the Initial Public Offering and the acquisition of the Purchased
Companies and the "Company" for both periods.
 
     The acquisitions of Northern, Paragon and Kemp have been treated as
business combinations accounted for by the purchase method of accounting as
prescribed by Accounting Principles Board Opinion No. 16 and SEC Staff
Accounting Bulletin No. 48. Northern and Kemp were valued at the fair market
value of consideration given. In connection with the acquisitions of Northern
and Kemp, the excess of consideration given over the fair market value of net
assets acquired are being amortized on a straight-line basis over 15 years. The
acquisition of Paragon's common stock in exchange for shares of the Company's
Common Stock was accounted for at Paragon's historical costs. The accompanying
consolidated financial statements include the accounts of Northern, Kemp and
Paragon from February 9, 1996, the effective date of the acquisitions. As a
result, the Company's statement of operations for the nine months ended
September 30, 1996 is not comparable to the statement of operations for the nine
months ended September 30, 1995, and the Company's balance sheet as of September
30, 1996 is not comparable to its balance sheet as of December 31, 1995.
 
     The consideration paid to the former owners of Northern, Kemp and Paragon
and the allocation of such consideration to the acquired assets is as follows:

2. INITIAL PUBLIC OFFERING OF COMMON STOCK
 
     On February 9, 1996, the Company completed the offering of 4,000,000 shares
of Common Stock at a price to the public of $7.50 per share. Subsequently, on
February 21, 1996, the underwriters exercised their overallotment option to
purchase an additional 600,000 shares at a price to the public of $7.50 per
share. The proceeds, net of the underwriters' discounts and the Company's
offering costs, were approximately $28,654,000. Of those net proceeds,
$3,510,000 was treated, for accounting purposes, as a dividend to the

former stockholders of GEO and PIASA, approximately $10,328,000 was used to
purchase Northern and all of the capital stock of Kemp, approximately $4,599,000
was used to retire certain indebtedness of the Operating Subsidiaries, $152,000
was used to retire capital leases and $1,149,000 was paid subsequent to the
closing of the acquisitions as a purchase price adjustment for the purchase of
the land-based seismic data operations of Northern. The Company recognized
$57,000 of extraordinary gain, net of tax, from the retirement of a certain
portion of this debt.
 
3. SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
     The Company generates revenue through performing seismic data acquisition.
Revenues from seismic data services are recognized as the work progresses on the
percentage of completion method.
 
     Net revenues for the nine months ended September 30, 1995 and 1996 included
contractual revenue adjustments from the Mexican operations for which the
related seismic data acquisition and geophysical services have been provided.
These revenue adjustments are based on independent economic data, primarily the
Mexican inflation rate as measured by the consumer price index. Certain of these
revenue adjustments recognized for the nine months ended September 30, 1996, for
which the Company has the contractual right to invoice, have not been invoiced
pending final review by the Company's major customer in Mexico. The Company,
historically, has not experienced difficulty in collecting these revenue
adjustments and, accordingly, the Company has not recorded a valuation allowance
against these amounts as of December 31, 1995 or September 30, 1996.
 
MAJOR CUSTOMER
 
     One customer, PEMEX, which is owned by the Mexican government, accounted
for approximately 98% of the revenues of the Predecessor for the year ended
December 31, 1995. As of December 31, 1994 and 1995, this customer accounted for
approximately 100% and 99%, respectively, of the Predecessor's trade accounts
receivable. As of September 30, 1996, two customers accounted for 29.1%, and
28.0% of the Successor's trade accounts receivable.
 
     During the nine months ended September 30, 1995, one customer accounted for
100% of net revenues of the Predecessor and during the nine months ended
September 30, 1996, three customers accounted for 25.1%, 18.1% and 16.4% of the
Successor's net revenues, respectively.
 
FOREIGN CURRENCY TRANSLATION
 
     The financial statements of the Predecessor and the operations of the
Successor in Mexico use the Mexican peso as the functional currency. Assets and
liabilities are translated into U.S. dollars at the prevailing exchange rate at
the respective balance sheet date. The resulting translation adjustments are
included in stockholders' equity. Income and expenses are translated at the
average exchange rate during the respective reporting period. Gains and losses
resulting from foreign currency transactions are included in income currently.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost, adjusted for accumulated
depreciation and amortization. Equipment held under capital leases is stated at
the present value of future minimum lease payments at the inception of the
leases. Property and equipment are depreciated on the straight-line method over
the estimated useful lives of the assets, which range from three to seven years.
Equipment held under capital leases is amortized on the straight-line method
over the estimated useful life of the assets or the terms of the lease.

3. SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts reported in the balance sheets for cash, accounts
receivable, accounts payable and notes payable approximate fair value because of
the immediate or short-term maturity of these financial instruments. The
carrying amount of the obligation under capital lease approximates fair value
because the lease agreements bear interest at variable rates which are adjusted
monthly. The carrying amounts reported for long-term debt approximates fair
value based on current replacement values.
 
ACCOUNTING FOR INCOME TAXES
 
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to the differences between the financial statement
carrying value of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured by using enacted tax
rates that are applicable to the future years in which deferred tax assets or
liabilities are expected to be realized or settled. The effect of a change in
tax rates on deferred tax assets and liabilities is recognized in earnings in
the period in which the tax rate change was enacted. The Company establishes a
valuation allowance when it is more likely than not that a deferred tax asset
will not be recovered.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In March 1995, the FASB issued Statement of Financial Accounting Standards
No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets To Be Disposed Of ("Statement 121"). Statement 121 addresses the
accounting for the impairment of long-lived assets, certain identifiable
intangibles and goodwill related to those assets to be held and used. It also
addresses the accounting for long-lived assets and certain identifiable
intangibles to be disposed of. Statement 121 establishes guidance for
recognizing and measuring impairment losses and requires that the carrying
amount of impaired assets be reduced to fair value. Statement 121 will be
effective for fiscal years beginning after December 15, 1995. Management does
not expect the impact of the adoption of Statement 121 to have a material
adverse effect on the Successor's financial condition or results of operations.
 
     During the fourth quarter of 1995, "Statement of Financial Accounting
Standards No. 123" (SFAS 123) was issued by the FASB. The Company will continue
to account for future grants of Common Stock options using the intrinsic value
method under Accounting Principles Board Opinion No. 25, "Accounting for Stock
issued to Employees" and will adopt the disclosure requirements of SFAS 123.
 
EARNINGS PER SHARE
 
     Earnings per share is computed using weighted average common shares
outstanding for the period. The number of shares used in the earnings per share
calculation for the nine months ended September 30, 1996 is determined as
follows:

3. SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
USE OF ESTIMATES
 
     The preparation of the 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 on December 31, 1994 and 1995
for the combined financial statements, and September 30, 1996 for the
consolidated financial statements and the reported amounts of revenue and
expenses during the reporting periods. A significant estimate in the preparation
of the Company's financial statements is related to the percentage of revenue
recognized based on the stage of completion of the Company's contracts. Actual
results could differ from those estimates.
 
4. PREPAID EXPENSES AND OTHER ASSETS

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The total accounts receivable serving as collateral under the factoring
agreements was approximately $260,000 at December 31, 1994. These invoices are
all stated in Mexican pesos which amounted to 1,300,000 pesos at December 31,
1994.
 
     On May 31, 1996, the Company acquired seismic data acquisition equipment
(the "Equipment") from the manufacturer thereof, Input/Output, Inc. for an
aggregate of approximately $8.5 million in cash and refinanced certain
conditional sales agreements with Input/Output, Inc. for an additional $4.5
million of equipment. A portion of the purchase price for the Equipment and the
funds for the refinancing were paid from the proceeds of a $12 million borrowing
under a $15 million term loan (the "Term Loan") from First Interstate Bank of
Texas, N.A. (the "Bank") pursuant to a Loan Agreement between the Company and
the Bank, dated as of May 29, 1996 (the "Loan Agreement"). The Term Loan is
payable in substantially equal monthly installments through July 31, 1999, bears
interest at an annual rate equal to the prime rate plus 1% (9.25% at September
30, 1996) and is secured by a lien on the Company's accounts, accounts
receivable, equipment, machinery, fixtures, inventory, goods, chattel paper,
documents, instruments, investment property, general intangibles, and other
personal property, whether then owned or thereafter acquired, and all products
and proceeds thereof, and by guarantees by certain of the Company's
subsidiaries. The Loan Agreement also provides for a $3 million revolving credit
loan (the "Revolving Credit Loan") which may be drawn down from time to time
through May 29, 1997 in an amount of up to 70% of the Company's "Eligible
Accounts" (as defined in the Loan Agreement). The rate of interest and the
security for the Revolving Credit Loan are the same as those described above for
the Term Loan. In addition to certain customary affirmative covenants, the Loan
Agreement contains restrictions on the Company with respect to (i) incurring
Debt (as defined), incurring or permitting to exist Liens (as defined) on its
property, assets or revenues, (iii) declaring or paying any dividends or other
distributions on its capital stock (or acquiring any of its capital stock), (iv)
issuing capital stock, (v) entering into transactions with affiliates, (vi)
disposing of assets, and (vii) certain other matters. The Loan Agreement also
contains financial covenants with respect to minimum tangible net worth, the
ratio of tangible net worth to net liabilities and the ratio of earnings to debt
service.
 
8. COMMITMENTS AND CONTINGENCIES
 
     Geoevaluaciones has a dispute, and may be threatened with litigation, in
connection with certain agreements it entered into with Capilano International
Inc., a Canadian company ("Capilano"). The dispute concerns a certain Letter of
Intent and a Technical Assistance Agreement, dated June 3, 1991 and June 1,
1992, respectively (the "Capilano Agreements"). Capilano stated in its 1994
Annual Report to Shareholders that it has had difficulty in collecting amounts
owing from a Mexican company (presumably, Geoevaluaciones) to which Capilano
supplied technical assistance and stated in its 1995 Annual Report that it had
written down by approximately C$1.9 million accounts receivable in Mexico.
Geoevaluaciones maintains that it is not obligated to compensate Capilano for
certain services Geoevaluaciones believes were either inadequately provided or
not provided at all by Capilano. Representatives of Capilano and Geoevaluaciones
have had ongoing discussions since May 1996 in an effort to resolve this
dispute. The Company currently is not able to estimate the effect, if any, on
its results of operations and financial position which may result from the
resolution of this matter. Therefore, the financial statements of the Company do
not reflect any adjustments related to this matter. A portion of the amounts
payable to the former stockholders of Geoevaluaciones in connection with the
acquisition by 3-D Geophysical of the stock of Geoevaluaciones owned by such
stockholders is held in escrow and available to pay amounts in settlement or
otherwise in connection with the dispute with Capilano.
 
     The Predecessor rents office facilities under annual operating leases. Rent
expense was $489,512, $302,140 and $298,900 for the years ended December 31,
1993, 1994 and 1995, respectively.

9. EXTRAORDINARY ITEM
 
     The Company recognized a $57,000 extraordinary item in the nine months
ended September 30, 1996, net of tax expense of $36,000. The extraordinary item
is due to a gain recognized on the early extinguishment of debt.

</TABLE>
 
     The deferred tax liability at December 31, 1993, 1994 and 1995 and
September 30, 1996 (unaudited) is the result of differences between the
financial statement carrying value and the tax basis of property and equipment.
 
     The effective income tax rates for the nine months ended September 30, 1995
and 1996 are 6% and 24%, respectively. The differences between the statutory
federal income tax rate on income before provision for income taxes and
extraordinary item, and the Company's effective income tax rate, result
primarily from the tax benefits associated with inflation adjustments with
respect to the operations of Geoevaluaciones and PIASA for the nine months ended
September 30, 1995 and the anticipated change in the valuation allowance
previously established with respect to net operating loss carryforwards and
inflation adjustments in Mexico for the nine months ended September 30, 1996.
 
11. COMMON STOCK
 
     The Predecessor is required under Mexican law to establish a legal reserve
equal to 5% of each company's earnings until such time as the reserve equals 20%
of the minimum capital of the company. In 1993, Geoevaluaciones capitalized
$229,582 of earnings.
 
     On February 9, 1996, the former stockholders of Geoevaluaciones (the
"Former Geoevaluaciones Stockholders") sold all of the issued and outstanding
shares of capital stock of Geoevaluaciones to the Company. Pursuant to the
Geoevaluaciones stock purchase agreement, the aggregate consideration paid to
the Former Geoevaluaciones Stockholders by the Company was: (i) $2.45 million
paid in cash at closing; and (ii) $1.0 million paid by delivery at closing of
four promissory notes, payable in installments at six, 12, 18 and 24 months
after the closing in following aggregate amounts (which amounts include interest
at 8% per

annum): $290,000, $280,000, $270,000 and $260,000, respectively. In connection
with this acquisition, each of the Former Geoevaluaciones Stockholders entered
into a separate non-competition agreement with the Company pursuant to which the
Company paid to the Former Geoevaluaciones Stockholders: (i) 100,000 shares of
Common Stock held in trusts with Mexican banks for the benefit of the Former
Geoevaluaciones Stockholders, and to be released February 9, 1998; and (ii) $2.0
million, reduced by the amount of any liabilities Geoevaluaciones had not
disclosed to 3-D and by any amount paid by Geoevaluaciones to settle or
otherwise in connection with Geoevaluaciones' dispute with Capilano, such
portion of the consideration consisting of (a) $1.0 million in cash deposited at
the closing in a bank account, and which, subject to any such reduction, may be
disbursed only upon the approval of certain individuals; and (b) 117,647 shares
of Common Stock to be delivered at closing to trusts with Mexican banks for the
benefit of the Former Geoevaluaciones Stockholders, and which may not be
released until June 30, 1997 and then only upon the approval of certain
individuals. Pursuant to such stock purchase agreement, the Company agreed to
assume up to an aggregate of $600,000 of the obligations under any borrowings of
Geoevaluaciones from a bank or other financial institution for working capital
purposes.
 
     On February 6, 1996, the former stockholders of PIASA, pursuant to a stock
purchase agreement dated November 7, 1995, sold all of the shares of capital
stock of PIASA to the Company. The aggregate consideration paid by the Company
was approximately $300,000, consisting of $60,000 in cash and approximately
28,235 shares of Common Stock.
 
     In October 1995, the Predecessor and Kemp Geophysical Corporation formed a
joint venture to perform certain land-based seismic data acquisition activities.
In November, the joint venture incurred debt (bearing interest at an annual rate
of 10.75% payable over three years) of $3.9 million to acquire an I/O SYSTEM
TWO(R) system. On July 1, 1996, the Company signed a dissolution agreement
terminating the joint venture which provided for the assets to be transferred to
Geoevaluacines. The debt was repaid in connection with the execution of the
Credit Facility as discussed in Note 7.

14. SUBSEQUENT EVENTS (UNAUDITED)
 
   
     On December 10, 1996, the Company entered into a stock purchase agreement
(the "Stock Purchase Agreement") to acquire J.R.S. Exploration Company Limited
("J.R.S. Exploration"), a land-based seismic data acquisition business
headquartered in Calgary, Alberta. Under the terms of the Stock Purchase
Agreement, the Company proposes to acquire all of the issued and outstanding
shares of capital stock of the intermediate holding companies that own all of
the issued and outstanding capital stock of J.R.S. Exploration for Canadian $3.5
million (approximately U.S. $2.6 million) in cash and a number of shares of the
Common Stock having a value of Canadian $3.35 million (approximately U.S. $2.5
million) valued on the basis of the average closing price of the Common Stock
prior to the closing. The acquisition is subject to certain customary
conditions. The closing of this proposed acquisition is anticipated to occur in
January 1997.
    
 
   
     On October 8, 1996, the Company filed a Registration Statement on Form S-1
(No. 333-13665) with the Securities and Exchange Commission relating to a
proposed underwritten sale to the public of 4,000,000 shares of Common Stock
(plus an over-allotment option of 600,000 shares). On November 19, 1996, the
Company filed an amendment to such registration statement and increased the
number of shares of Common Stock to be offered to 4,300,000 (plus an
over-allotment option of 645,000).
    
 
     In October 1996, the Company signed four separate lease agreements for the
lease of seismic data acquisition equipment with rental terms ranging from three
to six months and providing for aggregate minimum lease payments of
approximately $3.8 million. Two of the leases are with Andrews Group
International, a related party. Each of these two leases has a six month minimum
lease term and provides that the Company has the option to purchase the
equipment being leased, with 80% of rental payments applying towards the
purchase price. Minimum lease payments under these leases are approximately
$660,000 and $173,000, respectively.
 
     The Company also entered into two lease agreements with Geco-Prakla, a
division of Schlumberger Technology Corporation. One lease has a three-month
minimum lease term and provides that the Company has the option to purchase the
equipment being leased, with 75% of rental payments applying towards the
purchase price. Minimum lease payments under this lease are approximately
$338,000. The other lease has a three-month minimum lease term and contains no
option to purchase the equipment being leased. Minimum lease payments under this
lease are approximately $2.6 million.
 
   
     The Company believes that it is probable that the inflation rate in Mexico,
as measured by the consumer price index, will exceed 100% for the three-year
period ending December 31, 1996. Accordingly, the Company will likely adopt the
U.S. dollar as the functional currency for the Mexican Operations beginning on
January 1, 1997 in accordance with Statement of Financial Accounting Standards
No. 52. Using the U.S. Dollar as the functional currency will result in an
adjustment to the consolidated statement of operations for translation gains and
losses.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
  Northern Geophysical of America, Inc.:
 
     We have audited the accompanying balance sheet of the Land-Based Seismic
Data Operations of Northern Geophysical of America, Inc. (the "Company") as of
December 31, 1994 and September 30, 1995, and the related statements of
operations, changes in net equity and cash flows for each of the two years in
the period ended December 31, 1994 and the nine month period ended September 30,
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.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Land-Based Seismic Data
Operations of Northern Geophysical of America, Inc. as of December 31, 1994 and
September 30, 1995, and the results of its operations and its cash flows for
each of the two years in the period ended December 31, 1994 and the nine month
period ended September 30, 1995, in conformity with generally accepted
accounting principles.

                     NORTHERN GEOPHYSICAL OF AMERICA, INC.
                      (LAND-BASED SEISMIC DATA OPERATIONS)
 
                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation:
 
     The financial statements presented herein include the accounts of the
land-based seismic data operations (the "Company") of Northern Geophysical of
America, Inc. ("Northern"). Net equity presented in the accompanying financial
statements is principally the result of the Company's cash receipts and
disbursements which were processed through Northern's centralized cash
management system. Additionally, the accompanying financial statements do not
include certain debt obligations of Northern to its Parent (as defined below)
and related interest expense, which are collateralized by certain of the
Company's seismic equipment, because such debt was not specifically allocated to
the land-based seismic data operations in the past.
 
     At December 31, 1994, September 30, 1995 and December 31, 1995 (unaudited),
Fairwater Capital Corporation ("Fairwater" or the "Parent") held 81% of the
outstanding common stock of Northern, and all of the outstanding preferred stock
of Northern. The remaining outstanding common stock of Northern is held by
employees. The Company is engaged in land-based seismic data acquisition.
 
     On February 9, 1996, Northern sold certain of its assets and operations to
3-D Geophysical, Inc. ("3-D Geophysical"). The aggregate consideration paid by
3-D Geophysical was approximately $10.9 million cash, reduced by the amount of
any and all outstanding indebtedness of Northern secured by the assets acquired
by 3-D Geophysical other than indebtedness owed to affiliates of Northern, and
further reduced to the extent the net working capital, as defined, of the assets
acquired on the day of the closing was negative, or, alternatively, increased to
the extent such net working capital was positive. The sale of these assets
occurred simultaneously in conjunction with an initial public offering of
securities by 3-D Geophysical. Commencing February 9, 1996, the results of
operations of the Company are included in the financial statements of 3-D
Geophysical, Inc. and Subsidiaries.
 
  Revenue Recognition:
 
     Revenues from seismic and geophysical services are recorded based on the
percentage of completion method.
 
  Property and Equipment:
 
     Property and equipment are carried at cost and include assets under capital
leases which are carried at the lower of cost or present value of future minimum
lease payments at the inception of the lease. Maintenance and repairs are
charged to expense as incurred and expenditures for major improvements are
capitalized. Gains and losses from retirement or replacement are included in
operations.
 
     Depreciation and amortization of equipment, furniture and assets under
capital leases are provided over the estimated useful lives of the assets or the
term of the lease using the straight-line method.
 
  Concentration of Credit Risk:
 
     During the years ended December 31, 1993 and 1994, for the nine months
ended September 30, 1995 and for the year ended December 31, 1995, one customer
accounted for approximately 33%, 26%, 29% and 19.4% (unaudited), respectively,
of seismic and geophysical revenues.
 
     The Company has not incurred any credit losses relating to its seismic and
geophysical services. Allowances for potential credit losses relating to seismic
and geophysical revenues are not maintained nor does the Company require
collateral.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:
 
  General and Administrative Expenses:
 
     General and administrative expenses represent actual costs incurred by
Northern, except for certain costs not related to the land-based seismic data
operations which were determined based on number of employees. Management of the
Company believes the allocation method is reasonable.
 
  Income Taxes:
 
     Northern files federal and certain state income tax returns which include
the operations of the Company. For financial reporting purposes, the Company
computes its provision for income taxes on a separate company basis utilizing
the tax elections made by Northern.
 
  Unaudited Financial Information:
 
     In the opinion of management, the accompanying unaudited financial
statements contain all adjustments (consisting only of normal recurring items)
necessary to present fairly the financial condition, results of operations and
cash flows of the Company as of and for the year ended December 31, 1995.
 
  Use of Estimates
 
     The preparation of the 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 revenue and expenses during the reporting
periods. A significant estimate in the preparation of the Company's financial
statements is related to the percentage of revenue recognized based on the stage
of completion of the Company's contracts. Actual results could differ from those
estimates.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders of
Paragon Geophysical, Inc.:
 
     We have audited the accompanying balance sheet of Paragon Geophysical, Inc.
(as defined in Note 1) as of December 31, 1994 and September 30, 1995 and the
related statements of operations, stockholders' deficit and cash flows for the
period from August 25, 1994 through December 31, 1994, the period from January
1, 1994 through August 24, 1994, for the year ended December 31, 1993 and the
nine months ended September 30, 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 statements presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As explained in Note 1 to the financial statements, the Successor Company
purchased substantially all of the net assets of the Predecessor Company as of
August 25, 1994. The transaction was accounted for as a purchase whereby the
purchase price was allocated to the assets and liabilities of the Predecessor
based upon their estimated fair value as of August 25, 1994. Accordingly, the
financial statements of the Successor Company are not comparable to those of the
Predecessor Company.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Paragon Geophysical, Inc.
(as defined in Note 1) as of December 31, 1994 and September 30, 1995, and the
results of its operations and its cash flows for the period from August 25, 1994
through December 31, 1994, the period from January 1, 1994 through August 24,
1994, for the year ended December 31, 1993 and the nine months ended September
30, 1995 in conformity with generally accepted accounting principles.

     In connection with the Acquisition, the Seller relinquished the rights to
its name to the Buyer. Concurrent with the Acquisition, the Buyer sold certain
assets to the sole shareholder of the Seller for $19,400. For purposes of
identification and description, the Company is referred to as the "Predecessor"
for the period prior to the Acquisition, the "Successor" for the period
subsequent to the Acquisition and the "Company" for both periods.
 
     The Company is a land geophysical services company primarily engaged in the
contract acquisition of two and three dimensional seismic data. The Company was
founded in 1987 and has grown to include two offices (one in Mount Gilead, Ohio
and a second located in Millersburg, Ohio). As of December 31, 1995, the Company
employs approximately 50 workers and operates two crews primarily in the
Appalachian Basin. The main customers for seismic data are oil and gas
exploration companies.
 
     The unaudited pro forma results of operations for the year ended December
31, 1994 assuming the Successor had acquired the net assets of the Predecessor
as of the beginning of the year ended December 31, 1994 are as follows:

     Acquisition of the Company by 3-D Geophysical: In November 1995 the Company
entered into a merger agreement among the Company, 3-D Geophysical and a
subsidiary of 3-D Geophysical, Inc, ("3-D"). The Company merged with a
subsidiary of 3-D, with the Company being the surviving entity. The Company's
stockholders received approximately 1,314,261 shares of 3-D common stock in
connection with the merger. In addition, 3-D assumed approximately $4.8 million
of the Company's debt. Commencing February 9, 1996, the results of operations of
the Company are included in the financial statements of 3-D.
 
     Receivables:  The Company's trade and other receivables are primarily from
entities within the oil and gas industry. The Company has established an
allowance for doubtful accounts based upon the historical data of its customers
and other current information. Bad debt expense of $30,331, $25,125, $53,497,
$20,000, and $20,000 was charged to operations for the periods August 25, 1994
through December 31, 1994, January 1,

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

1994 through August 24, 1994, the year ended December 31, 1993, the nine months
ended September 30, 1995, and the year ended December 31, 1995, respectively.
 
     Property and Equipment:  Property and equipment is recorded at cost.
Depreciation and amortization is provided over their estimated useful lives and
applied on the straight-line and declining-balance methods. Expenditures for
maintenance, repairs and minor renewals are charged to earnings as incurred.
Expenditures for additions, improvements, replacements, betterments and major
renewals are capitalized. Costs of property and equipment sold or retired and
the related accumulated depreciation are removed from the accounts; resulting
gains or losses are included in earnings.
 
     Inventory:  Inventory represents explosive material used by the Company in
order to obtain seismological data. The inventory is stated at the lower of cost
or market. Cost is determined using the first-in, first-out method. Management
has determined no valuation allowance is necessary as of December 31, 1995.
 
     Organizational Costs:  The Company has capitalized costs incurred in the
organization of the Successor and is amortizing these costs over a five year
period using the straight-line method.
 
     Revenue Recognition:  Revenues from seismic and geophysical services are
recorded based on the percentage of completion method.
 
     Income Taxes:  Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to the differences between the financial
statement carrying value of existing assets and liabilities and their respective
tax bases. Deferred tax assets and liabilities are measured by using enacted tax
rates that are applicable to the future years in which deferred tax assets or
liabilities are expected to be realized or settled. The effect of a change in
tax rates on deferred tax assets and liabilities is recognized in net earnings
in the period in which the tax rate change was enacted. The Company establishes
a valuation allowance when it is more likely than not that a deferred tax asset
will not be recovered.
 
     Supplemental Cash Flows Information:  The Successor paid interest of
$69,810 and $269,750 during the period August 25, 1994 through December 31, 1994
and the nine months ended September 30, 1995, respectively. The Predecessor paid
interest of $11,411 and $144,843 during the period January 1, 1994 through
August 25, 1994 and the year ended December 31, 1993, respectively. The
Predecessor financed the purchase of five vehicles in 1994 for $104,653 and
seven vehicles in 1993 for $100,305. The Successor financed the purchase of
equipment and vehicles for $1,515,830 during the twelve months ended December
31, 1995.
 
     Unaudited Financial Information:  In the opinion of management, the
accompanying unaudited financial statements contain all adjustments (consisting
only of normal recurring items) necessary to present fairly the financial
position of the Company as of December 31, 1995 and the results of their
operations and cash flows for the year ended December 31, 1995.
 
USE OF ESTIMATES
 
     The preparation of the 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 combined
financial statements and the reported amounts of revenue and expenses during the
reporting periods. A significant estimate in the preparation of the Company's
financial statements is related to the percentage of revenue recognized based on
the stage of completion of the Company's contracts. Actual results could differ
from those estimates.

                                AUDITORS' REPORT
 
To the Directors of J.R.S. Exploration Company Limited:
 
We have audited the balance sheet of J.R.S. Exploration Company Limited as at
November 30, 1995 and the statements of operations and retained earnings and
changes in financial position for the year then ended. 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 audit.
 
We conducted our audit in accordance with generally accepted auditing standards
in Canada. Those standards require that we plan and perform an audit to obtain
reasonable assurance 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.
 
In our opinion, these financial statements present fairly, in all material
respects, the financial position of the Company as at November 30, 1995 and the
results of its operations and changes in its financial position for the year
then ended in accordance with generally accepted accounting principles in
Canada.

SMITH BARNEY INC.
RAUSCHER PIERCE REFSNES, INC.
SIMMONS & COMPANY INTERNATIONAL

         As Representatives of the Several Underwriters

c/o SMITH BARNEY INC.
         388 Greenwich Street
         New York, New York 10013

Dear Sirs:

         3-D Geophysical, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell an aggregate of 4,300,000 shares (the "Firm Shares")
of its common stock, $0.01 par value per share (the "Common Stock"), to the
several Underwriters named in Schedule I hereto (the "Underwriters").  The
Company also proposes to sell to the Underwriters, upon the terms and
conditions set forth in Section 2 hereof, up to an additional 645,000 shares
(the "Additional Shares") of Common Stock.  The Firm Shares and the Additional
Shares are hereinafter collectively referred to as the "Shares".

         The Company wishes to confirm as follows its agreement with you (the
"Representatives") and the other several Underwriters on whose behalf you are
acting, in connection with the several purchases of the Shares by the
Underwriters.

         1.      Registration Statement and Prospectus.  The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Act"), a registration statement on Form S-1 (Registration
No. 333-13665) under the Act (the "registration statement"), including a
prospectus subject to completion relating to the Shares.  The term
"Registration Statement" as used in this Agreement means the registration
statement (including all financial schedules and exhibits), as amended at the
time it becomes effective, or, if the registration statement became effective
prior to the execution of this Agreement, as supplemented or amended prior to
the execution of this Agreement.  If it is contemplated, at the time this
Agreement is executed, that a post-effective amendment to the registration
statement or a new registration statement pursuant to Rule 462(b) of the Act
will be filed and must be declared effective before the offering of the Shares
may commence, the term "Registration Statement" as used in this Agreement means
the registration statement as amended by said post-effective amendment or such
new registration statement.  The term "Prospectus" as used in this Agreement
means the prospectus in the form included in the Registration Statement, or, if
the prospectus included in the Registration Statement omits information in
reliance on Rule 430A under the Act and such information is 





<PAGE>   2

included in a prospectus filed with the Commission pursuant to Rule 424(b)
under the Act, the term "Prospectus" as used in this Agreement means the
prospectus in the form included in the Registration Statement as supplemented
by the addition of the Rule 430A information contained in the prospectus filed
with the Commission pursuant to Rule 424(b).  The term "Prepricing Prospectus"
as used in this Agreement means the prospectus subject to completion in the
form included in the registration statement at the time of the initial filing
of the registration statement with the Commission, and as such prospectus shall
have been amended from time to time prior to the date of the Prospectus.
        
         2.      Agreements to Sell and Purchase.  The Company hereby agrees,
subject to all the terms and conditions set forth herein, to issue and sell to
each Underwriter and, upon the basis of the representations, warranties and
agreements of the Company herein contained and subject to all the terms and
conditions set forth herein, each Underwriter agrees, severally and not
jointly, to purchase from the Company, at a purchase price of $________ per
Share (the "purchase price per share"), the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule I hereto (or such number of
Firm Shares increased as set forth in Section 10 hereof).

         The Company also agrees, subject to all the terms and conditions set
forth herein, to sell to the Underwriters, and, upon the basis of the
representations, warranties and agreements of the Company herein contained and
subject to all the terms and conditions set forth herein, the Underwriters
shall have the right to purchase from the Company, at the purchase price per
share, pursuant to an option (the "over-allotment option") which may be
exercised at any time and from time to time prior to 9:00 P.M., New York City
time, on the 30th day after the date of the Prospectus (or, if such 30th day
shall be a Saturday or Sunday or a holiday, on the next business day thereafter
when the New York Stock Exchange is open for trading), up to an aggregate of
600,000 Additional Shares.  Additional Shares may be purchased only for the
purpose of covering over-allotments made in connection with the offering of the
Firm Shares.  Upon any exercise of the over-allotment option, each Underwriter,
severally and not jointly, agrees to purchase from the Company the number of
Additional Shares (subject to such adjustments as you may determine in order to
avoid fractional shares) which bears the same proportion to the number of
Additional Shares to be purchased by the Underwriters as the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule I hereto (or
such number of Firm Shares increased as set forth in Section 10 hereof) bears
to the aggregate number of Firm Shares.

         3.      Terms of Public Offering.  The Company has been advised by you
that the Underwriters propose to make a public offering of their respective
portions of the Shares as soon after the Registration Statement and this
Agreement have become effective as in your judgment is advisable and initially
to offer the Shares upon the terms set forth in the Prospectus.

         4.      Delivery of the Shares and Payment Therefor.  Delivery to the
Underwriters of and payment for the Firm Shares shall be made at the office of
Fulbright & Jaworski L.L.P., 666 Fifth Avenue, New York 10103, at 10:00 A.M.,
New York City time, on            , 1996 (the "Closing Date").  The place of
closing for the Firm Shares and the Closing Date may be varied by agreement
between you and the Company.

         Delivery to the Underwriters of and payment for any Additional Shares
to be purchased by the Underwriters shall be made at the aforementioned office
of Smith Barney Inc. at such time on such date (the "Option Closing Date"),
which may be the same as the Closing Date but shall in no event be earlier than
the Closing Date nor earlier than two nor later than ten business days after
the giving of the notice hereinafter referred to, as shall be specified in a
written notice from you on 




                                     -2-
<PAGE>   3
behalf of the Underwriters to the Company of the Underwriters' determination to
purchase a number, specified in such notice, of Additional Shares.  The place
of closing for any Additional Shares and the Option Closing Date for such
Shares may be varied by agreement between you and the Company.
        
         Certificates for the Firm Shares and for any Additional Shares to be
purchased hereunder shall be registered in such names and in such denominations
as you shall request prior to 9:30 A.M., New York City time, on the second
business day preceding the Closing Date or any Option Closing Date, as the case
may be.  Such certificates shall be made available to you in New York City for
inspection and packaging not later than 9:30 A.M., New York City time, on the
business day next preceding the Closing Date or the Option Closing Date, as the
case may be.  The certificates evidencing the Firm Shares and any Additional
Shares to be purchased hereunder shall be delivered to you on the Closing Date
or the Option Closing Date, as the case may be, against payment of the purchase
price therefor in immediately available funds.

         5.      Agreements of the Company.  The Company agrees with the
several Underwriters as follows:

                 (a)      If, at the time this Agreement is executed and
delivered, it is necessary for the Registration Statement, a post-effective
amendment thereto or a new registration statement filed under Rule 462(b) to be
declared effective before the offering of the Shares may commence, the Company
will endeavor to cause the Registration Statement or such post-effective
amendment or new registration statement to become effective as soon as possible
and will advise you promptly and, if requested by you, will confirm such advice
in writing, when the Registration Statement or such post-effective amendment or
new registration statement has become effective.

   
                 (b)      The Company will advise you promptly and, if
requested by you, will confirm such advice in writing: (i) of any request by
the Commission for amendment of or a supplement to the Registration Statement,
any Prepricing Prospectus or the Prospectus or for additional information; (ii)
of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of the suspension of
qualification of the Shares for offering or sale in any jurisdiction or the
initiation of any proceeding for such purpose; and (iii) within the period of
time referred to in paragraph (f) below, of any change in the Company's
condition (financial or other), business, prospects, properties, net worth or
results of operations, or of the happening of any event, which makes any
statement of a material fact made in the Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the
making of any additions to or changes in the Registration Statement or the
Prospectus (as then amended or supplemented) in order to state a material fact
required by the Act or the regulations thereunder to be stated therein or
necessary in order to make the statements therein (with respect to the
Prospectus, in light of the circumstances under which they were made) not
misleading, or of the necessity to amend or supplement the Prospectus (as then
amended or supplemented) to comply with the Act or any state securities law.  
If at any time the Commission shall issue any stop order suspending the 
effectiveness of the Registration Statement, the Company will make every 
reasonable effort to obtain the withdrawal of such order at the earliest 
possible time.
    

                 (c)      The Company will furnish to you, without charge, four
signed copies of the registration statement as originally filed with the
Commission and of each amendment thereto, including financial statements and
all exhibits thereto, and will also furnish to you, without charge, 




                                     -3-
<PAGE>   4
such number of conformed copies of the registration statement as originally
filed and of each amendment thereto, but without exhibits, as you may request.

                 (d)      The Company will not (i) file any amendment to the
Registration Statement or make any amendment or supplement to the Prospectus of
which you shall not previously have been advised or to which you shall
reasonably object after being so advised or (ii) so long as, in the opinion of
counsel for the Underwriters, a Prospectus is required to be delivered in
connection with sales of Shares by any Underwriter or dealer, file any
information, documents or reports pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act"), without delivering a copy of such
information, documents or reports to you, as Representatives of the
Underwriters, prior to or concurrently with such filing.

                 (e)      Prior to the execution and delivery of this
Agreement, the Company has delivered to you, without charge, in such quantities
as you have reasonably requested, copies of each form of the Prepricing
Prospectus.  The Company consents to the use, in accordance with the provisions
of the Act and with the securities or Blue Sky laws of the jurisdictions in
which the Shares are offered by the several Underwriters and by dealers, prior
to the date of the Prospectus, of each Prepricing Prospectus so furnished by
the Company.

   
                 (f)      As soon after the execution and delivery of this
Agreement as possible and thereafter from time to time for such period as in
the opinion of counsel for the Underwriters a prospectus is required by the Act
to be delivered in connection with sales of Shares by any Underwriter or
dealer, the Company will expeditiously deliver to each Underwriter and each
dealer, without charge, as many copies of the Prospectus (and of any amendment
or supplement thereto) as you may request.  The Company consents to the use of
the Prospectus (and of any amendment or supplement thereto) in accordance with
the provisions of the Act and with the securities or Blue Sky laws of the
jurisdictions in which the Shares are offered by the several Underwriters and
by all dealers to whom Shares may be sold, both in connection with the offering
and sale of the Shares and for such period of time thereafter as the Prospectus
is required by the Act to be delivered in connection with sales of Shares by
any Underwriter or dealer.  If during such period of time any event shall occur
that in the judgment of the Company or in the opinion of counsel for the
Underwriters is required to be set forth in the Prospectus (as then amended or
supplemented) or should be set forth therein in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary to supplement or amend the Prospectus to
comply with the Act or any state securities law, the Company will forthwith 
prepare and, subject to the provisions of paragraph (d) above, file with the 
Commission an appropriate supplement or amendment thereto, and will 
expeditiously furnish to the Underwriters and dealers a reasonable number of 
copies thereof.  In the event that the Company and you, as Representatives of 
the several Underwriters, agree that the Prospectus should be amended or 
supplemented, the Company, if requested by you, will promptly issue a press 
release announcing or disclosing the matters to be covered by the proposed 
amendment or supplement.
    

                 (g)      The Company will cooperate with you and with counsel
for the Underwriters in connection with the registration or qualification of
the Shares for offering and sale by the several Underwriters and by dealers
under the securities or Blue Sky laws of such jurisdictions as you may
designate and will file such consents to service of process or other documents
necessary or appropriate in order to effect such registration or qualification;
provided that in no event shall the Company be obligated to qualify to do
business in any jurisdiction where it is not now so qualified 




                                     -4-
<PAGE>   5

or to take any action which would subject it to service of process in suits,
other than those arising out of the offering or sale of the Shares, in any
jurisdiction where it is not now so subject.
        
                 (h)      The Company will make generally available to its
security holders a consolidated earnings statement, which need not be audited,
covering a twelve-month period commencing after the effective date of the
Registration Statement and ending not later than 15 months thereafter, as soon
as practicable after the end of such period, which consolidated earnings
statement shall satisfy the provisions of Section ll(a) of the Act.
        
                 (i)      During the period of five years hereafter, the
Company will furnish to you (i) as soon as available, a copy of each report of
the Company mailed to stockholders or filed with the Commission, and (ii) from
time to time such other information concerning the Company as you may
reasonably request.

                 (j)      If this Agreement shall terminate or shall be
terminated after execution pursuant to any provisions hereof (otherwise than
pursuant to the second paragraph of Section 10 hereof or by notice given by you
terminating this Agreement pursuant to Section 10 or Section 11 hereof) or if
this Agreement shall be terminated by the Underwriters because of any failure
or refusal on the part of the Company to comply with the terms or fulfill any
of the conditions of this Agreement, the Company agrees to reimburse the
Representatives for all out-of-pocket expenses (including reasonable fees and
expenses of counsel for the Underwriters) incurred by you in connection
herewith.

                 (k)      The Company will apply the net proceeds from the sale
of the Shares substantially in accordance with the description set forth in the
Prospectus.

                 (l)      If Rule 430A of the Act is employed, the Company will
timely file the Prospectus pursuant to Rule 424(b) under the Act and will
advise you of the time and manner of such filing.

                 (m)      Except as provided in this Agreement, the Company
will not sell, offer to sell, solicit an offer to buy, contract to sell or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for or any rights to purchase
or acquire, shares of Common Stock, or grant any options  or warrants to
purchase Common Stock (other than the grant of options under the 3-D
Geophysical, Inc.  1995 Long-Term Incentive Compensation Plan, as amended (the
"Plan"), and Common Stock issuable upon exercise of options granted under the
Plan or otherwise to officers, directors and key employees of the Company), for
a period of 120 days after the date of the Prospectus, without the prior
written consent of Smith Barney Inc.

                 (n)      The Company has furnished to you "lock-up" letters,
in form and substance satisfactory to you, signed by each of its current
officers and directors.

                 (o)      Except as stated in this Agreement and in the
Prepricing Prospectus and Prospectus, the Company has not taken, nor will it
take, directly or indirectly, any action designed to or that might reasonably
be expected to cause or result in stabilization or manipulation of the price of

                 (p)      The Company will use its best efforts to have the
Shares listed, subject to notice of issuance, on the Nasdaq National Market
concurrently with the effectiveness of the registration statement.

         6.      Representations and Warranties of the Company.  The Company
represents and warrants to each Underwriter that:

                 (a)      Each Prepricing Prospectus included as part of the
registration statement as originally filed or as part of any amendment or
supplement thereto, or filed pursuant to Rule 424 under the Act, complied when
so filed in all material respects with the provisions of the Act.  The
Commission has not issued any order preventing or suspending the use of any
Prepricing Prospectus.
        
                 (b)      The registration statement in the form in which it
became or becomes effective and also in such form as it may be when any
post-effective amendment thereto shall become effective and the Prospectus and
any supplement or amendment thereto when filed with the Commission under Rule
424(b) under the Act, complied or will comply in all material respects with the
provisions of the Act and did not or will not at any such times contain 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 (with respect
to the Prospectus, in light of the circumstances under which they were made)
not misleading, except that this representation and warranty does not apply to
statements in or omissions from the registration statement or the Prospectus
made in reliance upon and in conformity with information furnished to the
Company in writing by or on behalf of any Underwriter through you expressly for
use therein.

                 (c)      All the outstanding shares of Common Stock of the
Company have been duly authorized and validly issued, are fully paid and
nonassessable and are free of any preemptive or similar rights; the Shares have
been duly authorized and, when issued and delivered to the Underwriters against
payment therefor in accordance with the terms hereof, will be validly issued,
fully paid and nonassessable and free of any preemptive or similar rights; and
the capital stock of the Company conforms to the description thereof in the
Registration Statement and the Prospectus.

                 (d)      The Company is a corporation duly organized and
validly existing in good standing under the laws of the State of Delaware with
full corporate power and authority to own, lease and operate its properties and
to conduct its business as described in the Registration Statement and the
Prospectus, and is duly registered and qualified to conduct its business and is
in good standing in each jurisdiction or place where the nature of its
properties or the conduct of its business requires such registration or
qualification, except where the failure so to register or qualify does not have
a material adverse effect on the condition (financial or other), business,
properties, net worth or results of operations of the Company and the
Subsidiaries (as hereinafter defined) taken as a whole (a "Material Adverse
Effect").

                 (e)      All the Company's subsidiaries (collectively, the
"Subsidiaries") (other than those Subsidiaries not required to be listed
pursuant to Item 601(a)(21)(ii) of Regulation S-K) are listed in an exhibit to
the Registration Statement.  Each Subsidiary is listed on Schedule II hereto
and is a corporation duly organized, validly existing and in good standing in
the jurisdiction of its incorporation, with full corporate power and authority
to own, lease and operate its properties and to conduct its business as
described in the Registration Statement and the Prospectus, and is duly
registered and qualified to conduct its business and is in good standing in
each jurisdiction or place 




                                     -6-
<PAGE>   7
where the nature of its properties or the conduct of its business requires such
registration or qualification, except where the failure so to register or
qualify does not have a Material Adverse Effect; all the outstanding shares of
capital stock of each of the Subsidiaries have been duly authorized and validly
issued, are fully paid and nonassessable, and are owned by the Company
directly, or indirectly through one of the other Subsidiaries, free and clear
of any lien, adverse claim, security interest, equity or other encumbrance.
        
                 (f)      There are no legal or governmental proceedings
pending or, to the knowledge of the Company, threatened, against the Company or
any of the Subsidiaries, or to which the Company or any of the Subsidiaries, or
to which any of their respective properties is subject, that are required to be
described in the Registration Statement or the Prospectus but are not described
as required, and there are no agreements, contracts, indentures, leases or
other instruments that are required to be described in the Registration
Statement or the Prospectus or to be filed as an exhibit to the Registration
Statement that are not described or filed as required by the Act.
        
   
                 (g)      Neither the Company nor any of the Subsidiaries is in
violation of its certificate or articles of incorporation or by-laws, or other
organizational documents, or of any law, ordinance, administrative or
governmental rule or regulation applicable to the Company or any of the
Subsidiaries or of any decree of any court or governmental agency or body having
jurisdiction over the Company or any of the Subsidiaries, or in default in the
performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any agreement,
indenture, lease or other instrument to which the Company or any of the
Subsidiaries is a party or by which any of them or any of their respective
properties may be bound, except such violations or defaults which would not,
either singly or in the aggregate, be reasonably likely to result in a Material
Adverse Effect.
    

                 (h)      Neither the issuance and sale of the Shares, the
execution, delivery or performance of this Agreement by the Company, nor the
consummation by the Company of the transactions contemplated hereby (i)
requires any consent, approval, authorization or other order of or registration
or filing with any court, regulatory body, administrative agency or other
governmental body, agency or official (except such as may be required for the
registration of the Shares under the Act and compliance with the securities or
Blue Sky laws of various jurisdictions, all of which have been or will be
effected in accordance with this Agreement) or conflicts or will conflict with
or constitutes or will constitute a breach of, or a default under, the
certificate or articles of incorporation or bylaws, or other organizational
documents, of the Company or any of the Subsidiaries or (ii) conflicts or will
conflict with or constitutes or will constitute a breach of, or a default
under, any material agreement, indenture, lease or other instrument to which
the Company or any of the Subsidiaries is a party or by which any of them or
any of their respective properties may be bound, or violates or will violate
any statute, law, regulation or filing or judgment, injunction, order or decree
applicable to the Company or any of the Subsidiaries or any of their respective
properties, or will result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of the Company or any of the
Subsidiaries pursuant to the terms of any agreement or instrument to which any
of them is a party or by which any of them may be bound or to which any of the
property or assets of any of them is subject.

                 (i)      The accountants, Coopers & Lybrand L.L.P. and Garrett
Powers, who have certified or shall certify the financial statements included
in the Registration Statement and the Prospectus (or any amendment or
supplement thereto) are independent public accountants as required by the Act.

                 (j)      The consolidated historical and pro forma financial
statements, together with related schedules and notes, included in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto) comply as to form in all material respects with the requirements of
the Act.  Such historical financial statements present fairly the consolidated
financial position, results of operations and changes in financial position of
the Company and the Subsidiaries on the basis stated in the Registration
Statement at the respective dates or for the respective periods to which they
apply and have been prepared in accordance with generally accepted accounting
principles ("GAAP") consistently applied throughout the periods involved,
except as disclosed therein.  The financial statements of Northern Geophysical
of America, Inc. (Land-based Seismic Data Operations) ("Northern"), Paragon
Geophysical, Inc. ("Paragon") and J.R.S. Exploration Company Limited
("J.R.S."), together with related schedules and notes, included in the
Registration Statement and the Prospectus (and any amendments or supplement
thereto) comply as to form in all material respects with the requirements of
the Act.  Such historical financial statements present fairly the financial
position, results of operations and changes in financial position of Northern,
Paragon and J.R.S., respectively, on the basis stated in the Registration
Statement at the respective dates and for the respective periods to which they
apply and have been prepared in accordance with GAAP consistently applied
throughout the periods involved, except as disclosed therein.  The pro forma
consolidated financial statements have been prepared on a basis consistent with
the historical consolidated financial statements of the Company and the
Subsidiaries and the historical financial statements of Northern, Paragon, and
Kemp Geophysical Corporation, except for the pro forma adjustments specified
therein, and give effect to assumptions made on a reasonable basis and present
fairly the historical and proposed transactions contemplated by the Prospectus. 
The other financial and statistical information and data included in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto) are accurately presented and prepared on a basis consistent with such
financial statements and the books and records of the Company and the
Subsidiaries.
        
                 (k)      The execution and delivery of, and the performance by
the Company of its obligations under, this Agreement have been duly and validly
authorized by the Company, and this Agreement has been duly executed and
delivered by the Company and constitutes the valid and legally binding
agreement of the Company, enforceable against the Company in accordance with
its terms, except as (i) the enforceability thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws affecting the rights of creditors generally and by general
equitable principles and (ii) to the extent that rights to indemnity and
contribution hereunder may be limited by federal or state securities laws.

                 (l)      Except as disclosed in the Registration Statement and
the Prospectus (or any amendment or supplement thereto), subsequent to the
respective dates as of which such information is given in the Registration
Statement and the Prospectus (or any amendment or supplement thereto), neither
the Company nor any of the Subsidiaries has incurred any liability or
obligation, direct or contingent, or entered into any transaction, not in the
ordinary course of business, that is material to the Company and the
Subsidiaries taken as a whole, and there has not been any change in the capital
stock, or material increase in the short-term debt or long-term debt, of the
Company or any of the Subsidiaries, or any material adverse change, or any
development involving or which may reasonably be expected to involve, a
prospective material adverse change, in the condition (financial or other),
business, net worth or results of operations of the Company and the
Subsidiaries taken as a whole.

                 (m)      Each of the Company and the Subsidiaries has good and
marketable title to all property (real and personal) described in the
Prospectus as being owned by it, free and clear of 




                                     -8-
<PAGE>   9

all liens, claims, security interests or other encumbrances except such as are
described in the Registration Statement and the Prospectus or in a document
filed as an exhibit to the Registration Statement and all the material property
described in the Prospectus as being held under lease by each of the Company
and the Subsidiaries is held by it under valid, subsisting and enforceable
leases.
        
                 (n)      The Company has not distributed and, prior to the
later to occur of (i) the Closing Date and (ii) completion of the distribution
of the Shares, will not distribute any offering material in connection with the
offering and sale of the Shares other than the Registration Statement, the
Prepricing Prospectus, the Prospectus or other materials, if any, permitted by
the Act.

                 (o)      The Company and each of the Subsidiaries has such
permits, licenses, franchises and authorizations of governmental or regulatory
authorities ("permits") as are necessary to own its respective properties and
to conduct its business in the manner described in the Prospectus, subject to
such qualifications as may be set forth in the Prospectus, except for such
permits the absence of which would not, either singly or in the aggregate, be
reasonably likely to result in a Material Adverse Effect; the Company and each
of the Subsidiaries has fulfilled and performed all its material obligations
with respect to such permits and no event has occurred which allows, or after
notice or lapse of time would allow, revocation or termination thereof or
results in any other material impairment of the rights of the holder of any
such permit, subject in each case to such qualification as may be set forth in
the Prospectus; and, except as described in the Prospectus, none of such
permits contains any restriction that is materially burdensome to the Company
or any of the Subsidiaries.
        
                 (p)      The Company and each of the Subsidiaries are in
material compliance with all Environmental Laws (defined below).  To the
Company's knowledge under current law, there are no existing circumstances that
would prevent, interfere with or increase the cost of such compliance in the
future, which prevention, interference or increase in cost is reasonably likely
to result in a Material Adverse Effect.  As used in this Agreement,
"Environmental Laws" means all United States or foreign federal, state, local
or municipal laws, rules, regulations, statutes, ordinances or orders of any
governmental entity relating to (i) the control of any potential pollutant or
protection of the air, water or land, (ii) solid, gaseous or liquid waste
generation, handling, treatment, storage, disposal or transportation, and (iii)
exposure to hazardous, toxic or other substances alleged to be harmful.

                 (q)      Except as disclosed in the Registration Statement and
the Prospectus (or any amendment or supplement thereto), there is no material
claim under any Environmental Law, including common law, pending or, to the
Company's knowledge, threatened against the Company or any of the Subsidiaries
("Environmental Claim") and, to the Company's best knowledge, under applicable
law, there are no past or present actions, activities, circumstances, events or
incidents, including, without limitation, releases of any material into the
environment that is reasonably likely to form the basis of any claim against
the Company or any of the Subsidiaries that, if determined adversely to the
Company or any of the Subsidiaries, is reasonably likely to result in a
Material Adverse Effect.

                 (r)      The Company maintains a system of internal accounting
controls sufficient to provide reasonable assurances that (i) transactions are
executed in accordance with management's general or specific authorization;
(ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's 




                                     -9-
<PAGE>   10

general or specific authorization; and (iv) the recorded accountability for
assets is compared with existing assets at reasonable intervals and appropriate
action is taken with respect to any differences.
        
                 (s)      To the Company's knowledge, neither the Company nor
any of its Subsidiaries nor any employee or agent of the Company or any
Subsidiary has made any payment of funds of the Company or any Subsidiary or
received or retained any funds in violation of any law, rule or regulation,
which payment, receipt or retention of funds is of a character required to be
disclosed in the Prospectus.

                 (t)      The Company and each of the Subsidiaries have filed
all tax returns required to be filed, which returns are complete and correct,
and neither the Company nor any Subsidiary is in default in the payment of any
taxes which were payable pursuant to said returns or any assessments with
respect thereto.

                 (u)      No holder of any security of the Company has any
right to require registration of shares of Common Stock or any other security
of the Company because of the filing of the registration statement or
consummation of the transactions contemplated by this Agreement.

                 (v)      The Company and the Subsidiaries own or possess all
patents, trademarks, trademark registrations, service marks, service mark
registrations, trade names, copyrights, licenses, inventions, trade secrets and
rights described in the Prospectus as being owned by them or any of them or
necessary for the conduct of their respective businesses, and the Company is
not aware of any claim to the contrary or any challenge by any other person to
the rights of the Company and the Subsidiaries with respect to the foregoing.

                 (w)      The Company is not now, and after sale of the Shares
to be sold by it hereunder and application of the net proceeds from such sale
as described in the Prospectus under the caption "Use of Proceeds" will not be,
an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

                 (x)      The Company has filed in a timely manner each
document or report required to be filed by it pursuant to the Exchange Act and
the rules and regulations thereunder; each such document or report at the time
it was filed conformed to the requirements of the Exchange Act and the rules
and regulations thereunder; and none of such documents or reports contained an
untrue statement of any material fact or omitted to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading.

                 (y)      The Company has complied with all provisions of
Florida Statutes, Section 517.075, relating to issuers doing business with
Cuba.

         7.      Indemnification and Contribution.

                 (a)      The Company agrees to indemnify and hold harmless
each of you and each other Underwriter and each person, if any, who controls
any Underwriter within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Prepricing Prospectus or in the Registration
Statement or the Prospectus or in any amendment or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein
a material 




                                    -10-
<PAGE>   11

fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any untrue statement or omission or
alleged untrue statement or omission which has been made therein or omitted
therefrom in reliance upon and in conformity with the information furnished in
writing to the Company by or on behalf of any Underwriter through you expressly
for use in connection therewith; provided, however, that the indemnification
contained in this paragraph (a) with respect to any Prepricing Prospectus shall
not inure to the benefit of any Underwriter (or to the benefit of any person
controlling such Underwriter) on account of any such loss, claim, damage,
liability or expense arising from the sale of the Shares by such Underwriter to
any person if a copy of the Prospectus shall not have been delivered or sent to
such person within the time required by the Act and the regulations thereunder,
and the untrue statement or alleged untrue statement or omission or alleged
omission of a material fact contained in such Prepricing Prospectus was
corrected in the Prospectus, provided that the Company has delivered the
Prospectus to the several Underwriters in requisite quantity on a timely basis
to permit such delivery or sending.  The foregoing indemnity agreement shall be
in addition to any liability which the Company may otherwise have.
        
                 (b)      If any action, suit or proceeding shall be brought
against any Underwriter or any person controlling any Underwriter in respect of
which indemnity may be sought against the Company, such Underwriter or such
controlling person shall promptly notify the Company, and the Company shall
assume the defense thereof, including the employment of counsel and payment of
all fees and expenses.  Such Underwriter or any such controlling person shall
have the right to employ separate counsel in any such action, suit or
proceeding and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Underwriter or such controlling
person unless (i) the Company has agreed in writing to pay such fees and
expenses, (ii) the Company has failed to assume the defense and employ counsel,
or (iii) the named parties to any such action, suit or proceeding (including
any impleaded parties) include both such Underwriter or such controlling person
and the Company and such Underwriter or such controlling person shall have been
advised by its counsel that representation of such indemnified party and the
Company by the same counsel would be inappropriate under applicable standards
of professional conduct (whether or not such representation by the same counsel
has been proposed) due to actual or potential differing interests between them
(in which case the Company shall not have the right to assume the defense of
such action, suit or proceeding on behalf of such Underwriter or such
controlling person).  It is understood, however, that the Company shall, in
connection with any one such action, suit or proceeding or separate but
substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such
Underwriters and controlling persons not having actual or potential differing
interests with you or among themselves, which firm shall be designated in
writing by Smith Barney Inc., and that all such fees and expenses shall be
reimbursed as they are incurred.  The Company shall not be liable for any
settlement of any such action, suit or proceeding effected without its written
consent, but if settled with such written consent, or if there be a final
judgment for the plaintiff in any such action, suit or proceeding, the Company
agrees to indemnify and hold harmless any Underwriter, to the extent provided
in the preceding paragraph, and any such controlling person from and against
any loss, claim, damage, liability or expense by reason of such settlement or
judgment.

                 (c)      Each Underwriter agrees, severally and not jointly,
to indemnify and hold harmless the Company, its directors, its officers who
sign the Registration Statement, and any person who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the 




                                    -11-
<PAGE>   12

Exchange Act, to the same extent as the foregoing indemnity from the Company to
each Underwriter, but only with respect to information furnished in writing by
or on behalf of such Underwriter through you expressly for use in the
Registration Statement, the Prospectus or any Prepricing Prospectus, or any
amendment or supplement thereto.  If any action, suit or proceeding shall be
brought against the Company, any of its directors, any such officer, or any
such controlling person based on the Registration Statement, the Prospectus or
any Prepricing Prospectus, or any amendment or supplement thereto, and in
respect of which indemnity may be sought against any Underwriter pursuant to
this paragraph (c), such Underwriter shall have the rights and duties given to
the Company by paragraph (b) above (except that if the Company shall have
assumed the defense thereof such Underwriter shall not be required to do so,
but may employ separate counsel therein and participate in the defense thereof,
but the fees and expenses of such counsel shall be at such Underwriter's
expense), and the Company, its directors, any such officer, and any such
controlling person shall have the rights and duties given to the Underwriters
by paragraph (b) above. The foregoing indemnity agreement shall be in addition
to any liability which the Underwriters may otherwise have.
        
                 (d)      If the indemnification provided for in this Section 7
is unavailable to an indemnified party under paragraphs (a) or (c) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriters on the other hand from the
offering of the Shares, or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company on the one hand and the Underwriters on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the
table on the cover page of the Prospectus.  The relative fault of the Company
on the one hand and the Underwriters on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company on the one hand or
by the Underwriters on the other hand and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

                 (e)      The Company and the Underwriters agree that it would
not be just and equitable if contribution pursuant to this Section 7 were
determined by a pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to in paragraph (d)
above.  The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities and expenses referred to in paragraph (d)
above shall be deemed to include, subject to the limitations set forth above,
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating any claim or defending any such action, suit or
proceeding.  Notwithstanding the provisions of this Section 7, no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price of the Shares underwritten by it and distributed to the public
exceeds the amount of any damages which such Underwriter has otherwise 




                                    -12-
<PAGE>   13

been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations to contribute pursuant to
this Section 7 are several in proportion to the respective numbers of Firm
Shares set forth opposite their names in Schedule I hereto (or such numbers of
Firm Shares increased as set forth in Section 10 hereof) and not joint.
        
                 (f)      No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any pending
or threatened action, suit or proceeding in respect of which any indemnified
party is or could have been a party and indemnity could have been sought
hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such action, suit or proceeding.

                 (g)      Any losses, claims, damages, liabilities or expenses
for which an indemnified party is entitled to indemnification or contribution
under this Section 7 shall be paid by the indemnifying party to the indemnified
party as such losses, claims, damages, liabilities or expenses are incurred. 
The indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its directors or officers, or any person
controlling the Company, (ii) acceptance of any Shares and payment therefor
hereunder, and (iii) any termination of this Agreement.  A successor to any
Underwriter or any person controlling any Underwriter, or to the Company, its
directors or officers, or any person controlling the Company, shall be entitled
to the benefits of the indemnity, contribution and reimbursement agreements
contained in this Section 7.
        
         8.      Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Shares hereunder are
subject to the following conditions:

                 (a)      If, at the time this Agreement is executed and
delivered, it is necessary for the registration statement or a post-effective
amendment thereto or a new registration statement filed pursuant to Rule 462(b)
under the Act to be declared effective before the offering of the Shares may
commence, the registration statement or such post-effective amendment or such
new registration statement shall have become effective not later than 5:30
P.M., New York City time, on the date hereof, or at such later date and time as
shall be consented to in writing by you, and all filings, if any, required by
Rules 424 and 430A under the Act shall have been timely made; no stop order
suspending the effectiveness of the registration statement shall have been
issued and no proceeding for that purpose shall have been instituted or, to the
knowledge of the Company or any Underwriter, threatened by the Commission, and

prospective change, in or affecting the condition (financial or other),
business, properties, net worth, or results of operations of the Company and
the Subsidiaries taken as a whole not contemplated by the Prospectus, which in

or director of the Company which makes any statement made in the Prospectus
untrue or which, in the opinion of the Company and its counsel or the
Underwriters and their counsel, requires the making of any addition to or
change in the Prospectus in order to state a material fact required by the Act
or any other law to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, if amending or supplementing the Prospectus to reflect
such event or development would, in your reasonable opinion, as Representatives
of the several Underwriters, materially adversely affect the market for the
Shares.

duly registered and qualified to conduct its business and is in good standing
in each jurisdiction or place where the nature of its properties or the conduct
of its business requires such registration or qualification, except where the

of operations of the Company and the Subsidiaries taken as a whole;
        
   
                          (ii)    Each of the Subsidiaries, with the exception

                          (vii)   The Registration Statement and all

Commission; and any required filing of the Prospectus pursuant to Rule 424(b)
has been made in accordance with Rule 424(b);

                          (viii)  The Company has corporate power and authority

Underwriters as provided herein, and this Agreement has been duly authorized,
executed and delivered by the Company and is a valid, legal and binding
agreement of the Company, enforceable against the Company in accordance with
its terms, except as enforcement of rights to indemnity and contribution

incorporation or bylaws, or other organizational documents;
    
        
   
                          (x)     Neither the offer, sale or delivery of the
Shares, the execution, delivery or performance of this Agreement, compliance by
the Company with the provisions hereof nor consummation by the Company of the
transactions contemplated hereby conflicts with or constitutes a breach of, or a
default under, the certificate or articles of incorporation or bylaws, or other
organizational documents, of the Company or any of the Subsidiaries, with the
exception of the Mexican Subsidiaries and 3-D of Latin America, or any
agreement, indenture, lease or other instrument to which the Company or any of
the Subsidiaries, with the exception of the Mexican Subsidiaries and 3-D of
Latin America, is a party or by which any of them or any of their respective
properties is bound that is an exhibit to the Registration Statement, or is
known to such counsel after reasonable inquiry, or will result in the creation
or imposition of any lien, charge or encumbrance upon any property or assets of
the Company or any of the Subsidiaries, nor will any such action result in any
violation of any existing law, regulation, ruling (assuming compliance with all
applicable federal and state securities and Blue Sky laws) of the United States,
the State of New York or the General Corporation Law of the State of Delaware,
judgment, injunction, order or decree known to such counsel after reasonable
inquiry, applicable to the Company, the Subsidiaries or any of their respective
properties;
    

                          (xi)    No consent, approval, authorization or other
order of, or registration or filing with, any court, regulatory body,
administrative agency or other governmental body, agency, or official is
required on the part of the Company (except as have been obtained under the Act
or such as may be required under state securities or Blue Sky laws governing
the purchase and 




                                    -15-

distribution of the Shares) for the valid issuance and sale of the Shares to
the Underwriters as contemplated by this Agreement;
        
                          (xii)   The Registration Statement and the Prospectus
and any supplements or amendments thereto (except for the financial statements
and the notes thereto and the schedules and other financial and statistical
data included therein, as to which such counsel need not express any opinion)
comply as to form in all material respects with the requirements of the Act;

                          (xiii)  To the knowledge of such counsel after
reasonable inquiry, (A) other than as described or contemplated in the
Prospectus (or any supplement thereto), there are no legal or governmental
proceedings pending or threatened against the Company or any of the
Subsidiaries, or to which the Company or any of the Subsidiaries, or any of
their property, is subject, which are required to be described in the
Registration Statement or Prospectus (or any amendment or supplement thereto)
and (B) there are no agreements, contracts, indentures, leases or other
instruments that are required to be described in the Registration Statement or
the Prospectus (or any amendment or supplement thereto) or to be filed as an
exhibit to the Registration Statement that are not described or filed as
required, as the case may be;
        
   
    
   
                          (xiv)    The statements in the Registration Statement
and Prospectus, insofar as they are descriptions of contracts, agreements or
other legal documents, or refer to statements of law or legal conclusions, are
accurate and present fairly the information required to be shown;
    

                          Such counsel shall also state that although counsel
has not undertaken, except as otherwise indicated in their opinion, to
determine independently, and does not assume any responsibility for, the
accuracy or completeness of the statements in the Registration Statement, such
counsel has participated in the preparation of the Registration Statement and
the Prospectus, including review and discussion of the contents thereof, and
nothing has come to the attention of such counsel that has caused it to believe
that the Registration Statement at the time the Registration Statement became
effective, or the Prospectus, as of its date and as of the Closing Date or the
Option Closing Date, as the case may be, contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein (as to the Prospectus, in the light
of the circumstances under which they were made) not misleading or that any
amendment or supplement to the Prospectus, as of its respective date, and as of
the Closing Date or the Option Closing Date, as the case may be, contained any
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading (it being understood
that such counsel need make no statement with respect to the financial
statements and the notes thereto and the schedules and other financial and
statistical data included in the Registration Statement or the Prospectus).

         In rendering their opinion as aforesaid, counsel may rely upon an
opinion or opinions, each dated the Closing Date, of other counsel retained by
them or the Company as to laws of any jurisdiction other than the United States
or the State of New York, provided that (A) each such local counsel is
acceptable to the Representatives, (B) such reliance is expressly authorized by
each opinion so relied upon and a copy of each such opinion is delivered to the
Representatives and is, in form and substance satisfactory to them and their
counsel, and (C) counsel shall state in their opinion that they believe that
they and the Underwriters are justified in relying thereon.

                 (d)      You shall have received on the Closing Date, an
opinion of De Ovando y Martinez del Campo, S.C., counsel for the Mexican
Subsidiaries, dated the Closing Date and addressed to you, as Representatives
of the several Underwriters, as to the Mexican Subsidiaries with respect to the

                 (g)(i)  No stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for that
purpose shall have been taken or, to the knowledge of the Company, shall be
contemplated by the Commission at or prior to the Closing Date; (ii) there
shall not have been any change in the capital stock of the Company (except 
upon the grant of options under the Company's 1995 Long-Term Incentive 
Compensation Plan or the exercise of options) nor any material increase in the
short-term or long-term debt of the Company (other than in the ordinary course
of business) from that set forth or contemplated in the Registration Statement
or the Prospectus (or any amendment or supplement thereto); (iii) there shall
not have been, since the respective dates as of which information is given in
the Registration Statement and the Prospectus (or any amendment or supplement

                 (h)      The Company shall not have failed at or prior to the

         All such opinions, certificates, letters and other documents will be

         Any certificate or document signed by any officer of the Company and

         9.      Expenses.  The Company agrees to pay the following costs and

         10.     Effective Date of Agreement.  This Agreement shall become
effective: (a) upon the execution and delivery hereof by the parties hereto; or
(b) if, at the time this Agreement is executed and delivered, it is necessary
for the registration statement or a post-effective amendment thereto to be
declared effective before the offering of the Shares may commence or a new
registration statement to be filed pursuant to Rule 462(b) of the Act, when
notification of the effectiveness of the registration statement or such
post-effective amendment has been released by the Commission or when such new
registration statement has been filed pursuant to Rule 462(b) of the Act.
Until such time as this Agreement shall have become effective, it may be
terminated by the Company, by notifying you, or by you, as Representatives of
the several Underwriters, by notifying the Company.

         If any one or more of the Underwriters shall fail or refuse to
purchase Shares which it or they are obligated to purchase hereunder on the
Closing Date, and the aggregate number of Shares which such defaulting
Underwriter or Underwriters are obligated but fail or refuse to purchase is not
more than one-tenth of the aggregate number of Shares which the Underwriters
are obligated to purchase on the Closing Date, each non-defaulting Underwriter
shall be obligated, severally, in the proportion which the number of Firm
Shares set forth opposite its name in Schedule I hereto bears to the aggregate
number of Firm Shares set forth opposite the names of all non-defaulting
Underwriters or in such other proportion as you may specify in accordance with
Section 20 of the Master Agreement Among Underwriters of Smith Barney Inc., to
purchase the Shares which such defaulting Underwriter or Underwriters are
obligated, but fail or refuse, to purchase.  If any one or more of the
Underwriters shall fail or refuse to purchase Shares which it or they are
obligated to purchase on the Closing Date and the aggregate number of Shares
with respect to which such default occurs is more than one-tenth of the
aggregate number of Shares which the Underwriters are obligated to purchase on
the Closing Date and arrangements satisfactory to you and the Company for the
purchase of such Shares by one or more non-defaulting Underwriters or other
party or parties approved by you and the Company are not made within 36 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter or the Company.  In any such case which does
not result in termination of this Agreement, either you or the Company shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and the Prospectus or any other documents or arrangements may be
effected.  Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any such default of any
such Underwriter under this Agreement.  The term "Underwriter" as used in this
Agreement includes, for all purposes of this Agreement, any party not listed in
Schedule I hereto who, with your approval and the approval of the Company,
purchases Shares which a defaulting Underwriter is obligated, but fails or
refuses, to purchase.
        
         Any notice under this Section 10 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

         11.     Termination of Agreement.  This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Underwriter to the Company, by notice to the Company, if prior to the Closing
Date or any Option Closing Date (if different from the Closing Date and then
only as to the Additional Shares), as the case may be, (i) trading in
securities generally on the New York Stock Exchange, the American Stock
Exchange or the Nasdaq National Market shall have been suspended or materially
limited, (ii) a general moratorium on commercial banking activities in New York
or Colorado shall have been declared by either federal or state authorities, or
(iii) there shall have occurred any outbreak or escalation of hostilities or
other international or domestic calamity, crisis or change in political,
financial or economic conditions, the effect of which 




                                    -19-
<PAGE>   20

on the financial markets of the United States is such as to make it, in your
reasonable judgment, impracticable or inadvisable to commence or continue the
offering of the Shares at the offering price to the public set forth on the
cover page of the Prospectus or to enforce contracts for the resale of the
Shares by the Underwriters.  Notice of such termination may be given to the
Company by telegram, telecopy or telephone and shall be subsequently confirmed
by letter.
        
         12.     Information Furnished by the Underwriters.  The statements set
forth in the last paragraph on the cover page, the stabilization legend on the
inside cover page, and the statements in the first and third paragraphs under
the caption "Underwriting" in any Prepricing Prospectus and in the Prospectus,
constitute the only information furnished by or on behalf of the Underwriters
through you as such information is referred to in Sections 6(b) and 7 hereof.

         13.     Miscellaneous.  Except as otherwise provided in Sections 5, 10
and 11 hereof, notice given pursuant to any provision of this Agreement shall
be in writing and shall be delivered (a) if to the Company, at the office of
the Company at 7076 South Alton Way, Building H, Englewood, Colorado 80112,
Attention:  Richard Davis, President and Chief Executive Officer; or (ii) if to
you, as Representatives of the several Underwriters, care of Smith Barney Inc.,
388 Greenwich Street, New York, New York 10013, Attention: Manager, Investment
Banking Division.

         This Agreement has been and is made solely for the benefit of the
several Underwriters, the Company, its directors and officers, and the other
controlling persons referred to in Section 7 hereof and their respective heirs,
personal representatives, successors and assigns, to the extent provided
herein, and no other person shall acquire or have any right under or by virtue
of this Agreement.  Neither the term "successor" nor the term "successors and
assigns" as used in this Agreement shall include a purchaser from any
Underwriter of any of the Shares in his status as such purchaser.

         14.     Applicable Law; Counterparts.  This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed within the State of New York.

         This Agreement may be signed in various counterparts which together
constitute one and the same instrument.  If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof
shall have been executed and delivered on behalf of each party hereto.

                                   ARTICLE XI

                                Indemnification

                 11.1     Survival of Representations, Warranties and
Covenants.  The representations, warranties and covenants of the parties
contained in this Agreement, any Schedule or any certificate delivered pursuant
hereto shall survive the Closing.  Each party hereto shall be entitled to rely
on any such representation or warranty regardless of any inquiry or
investigation made by on behalf of such party.

                 11.2     Indemnification by Sellers.  Sellers shall jointly
and severally indemnify and hold harmless 3-D, Buyer, Company and their
respective directors, officers and employees from and against any Loss incurred
or suffered by such Person as a result of, arising from or in connection with:

                 (i)      a breach by a Seller of any representation or
         warranty made by such Seller in this Agreement or in any Schedule or
         certificate delivered pursuant hereto; and

                 (ii)     a failure by a Seller to perform or comply with any
         covenant or agreement on the part of such Seller contained herein,
         including any covenant contained in Article VI.

The amount paid pursuant to the preceding sentence shall be paid to Buyer or,
at Buyer's election, to Company and shall be the amount required to put Buyer
or Company, as the case may be, in the after tax position it would have been in
had such representation, warranty, covenant or agreement not been breached.
Any payment made by a Seller to Buyer under this Section 11.2 shall be treated
as a reduction in the aggregate consideration received by such Seller from
Buyer pursuant to this Agreement.  Any such payment made by a Seller to Company
shall be treated as a capital contribution to Company.

                 11.3     Indemnification by 3-D and Buyer.  3-D and Buyer
shall jointly and severally indemnify and hold harmless each Seller from and
against any Loss incurred or suffered by such Seller as a result of, arising
from or in connection with:

                 (i)      a breach by 3-D or Buyer of any representation or
         warranty made by 3-D or Buyer in this Agreement or in any Schedule or
         certificate delivered pursuant hereto or in the Support Agreement or
         the Share Exchange Agreement; and

                 (ii)     a failure by 3-D or Buyer to perform or comply with
         any covenant or agreement on the part of 3-D or Buyer contained
         herein, including any covenant contained in Article VII, or in the
         Support Agreement or the Share Exchange Agreement.

                 11.4     Assumption of Defense.  An indemnified party shall
promptly give notice to each indemnifying party after obtaining knowledge of
any matter as to which





                                      -36-
<PAGE>   42
recovery may be sought against such indemnifying party because of the indemnity
set forth above, and, if such indemnity shall arise from the claim of a third
party, shall permit such indemnifying party to assume the defense of any such
claim or any litigation resulting from such claim; provided, however, that
failure promptly to give any such notice shall not affect the indemnification
provided under this Article XI except to the extent such indemnifying party
shall have been prejudiced as a result of such failure.  Notwithstanding the
foregoing, an indemnifying party may not assume the defense of any such
third-party claim if it does not demonstrate to the reasonable satisfaction of
the indemnified party that it has adequate financial resources to defend such
claim and pay any and all Losses that may result therefrom, or if the claim (i)
is reasonably likely to result in imprisonment of the indemnified party, (ii)
is reasonably likely to result in a criminal penalty or fine against the
indemnified party the consequences of which would be reasonably likely to have
a material adverse effect on the indemnified party unrelated to the size of
such penalty or fine, or (iii) is reasonably likely to result in an equitable
remedy which would materially impair the indemnified party's ability to
exercise its rights under this Agreement, or impair 3-D's or Buyer's right or
ability to operate Company.  If an indemnifying party assumes the defense of
such third party claim, such indemnifying party shall agree prior thereto in
writing that it is liable under this Article XI to indemnify the indemnified
party in accordance with the terms contained herein in respect of such claim,
shall conduct such defense diligently, shall have full and complete control
over the conduct of such proceeding on behalf of the indemnified party and
shall, in his or her or its sole discretion, have the right to decide all
matters of procedure, strategy, substance and settlement relating to such
proceeding; provided, however, that any counsel chosen by such indemnifying
party to conduct such defense shall be reasonably satisfactory to the
indemnified party.  The indemnified party may participate in such proceeding
and retain separate co-counsel at its sole cost and expense, and the
indemnifying party will not without the written consent of the indemnified
party consent to the entry of any judgment or enter into any settlement with
respect to the matter which does not include a provision whereby the plaintiff
or the claimant in the matter releases the indemnified party from all liability
with respect thereto.  Failure by an indemnifying party to notify the
indemnified party of its election to defend any such claim or action by a third
party within thirty (30) days after notice thereof shall have been given to
such indemnifying party by the indemnified party shall be deemed a waiver by
such indemnifying party of its right to defend such claim or action.

                 11.5     Non-Assumption of Defense.  If no indemnifying party
is permitted or elects to assume the defense of any such claim by a third party
or litigation resulting therefrom, the indemnified party shall diligently
defend against such claim or litigation in such manner as it may deem
appropriate and, in such event, the indemnifying party or parties shall
promptly reimburse the indemnified party for all reasonable out-of-pocket costs
and expenses, legal or otherwise, incurred by the indemnified party and its
affiliates in connection with the defense against such claim or litigation, as
such costs and expenses are incurred.  Any counsel chosen by such indemnified
party to conduct such defense must be reasonably satisfactory to the
indemnifying party or parties, and only one counsel shall be retained to
represent all indemnified parties in an action (except that if litigation is
pending in more than one jurisdiction with respect to an action, one such
counsel may be retained in each jurisdiction in which such litigation is
pending).

                 11.6     Indemnified Party's Cooperation as to Proceedings.
The indemnified party will cooperate in all reasonable respects with any
indemnifying party in the conduct of any proceeding as to which such
indemnifying party assumes the defense.  For the cooperation of the indemnified
party pursuant to this Section 11.6, the indemnifying party or parties shall
promptly reimburse the indemnified party for all reasonable out-of-pocket costs
and expenses, legal or otherwise, incurred by the indemnified party or its
affiliates in connection therewith, as such costs and expenses are incurred.

                 11.7     General Limitations on Indemnification.

                 (a)  An indemnifying party shall not be liable to nor required
to indemnify or hold an indemnified party harmless with respect to any Loss to
the extent such Loss is recoverable under insurance policies maintained by the
indemnified party or its affiliates.

                 (b)      If any Loss indemnified against under this Article XI
shall result (after giving effect to any differences in the timing of
recognition, payment and deductibility) in a direct or indirect Tax savings to
the indemnified party or its affiliates, then the Indemnification Obligations
to which such indemnified party shall be entitled hereunder shall be reduced by
the amount of such Tax savings.


                                  ARTICLE XII

                                 Miscellaneous

                 12.1     Expenses.  Whether or not the transactions

expenses incurred by such party in respect of the transactions contemplated
hereby.

                 12.2     Entirety of Agreement.  This Agreement (including the

the other documents and certificates delivered hereunder, state the entire
agreement of the parties, merge all prior negotiations, agreements and
understandings, if any, and state in full all representations, warranties,
covenants and agreements which have induced this Agreement.  Each party agrees
that in dealing with third parties no contrary representations will be made.

                 12.3     Notices.  All notices and demands of any kind which
any party hereto may be required or desire to serve upon another party under

other party:  (a) by personal service upon such other party at such other
party's address set forth on the signature pages of this Agreement; or (b) by
mailing a copy thereof by certified or registered mail, postage prepaid, with
return receipt requested, addressed to such other party at the address of such
other party set forth on the signature pages of this Agreement; or (c) by

                                      -38-

other party at the address of such other party set forth on the signature pages

                 In case of service by Federal Express or equivalent courier
service or by facsimile or by personal service, such service shall be deemed
complete upon receipt.  In the case of service by mail, such service shall be
deemed complete on the fifth Business Day after mailing.  The addresses and
facsimile numbers to which, and persons to whose attention, notices and demands
shall be delivered or sent may be changed from time to time by notice served,
as hereinabove provided, by any party upon the other party.

                 12.4     Amendment.  This Agreement may be modified or amended
only by an instrument in writing, duly executed by all of the parties hereto.

                 12.5     Nonwaiver.  No waiver by any party of any term,
provision, covenant, representation or warranty contained in this Agreement (or
any breach thereof) shall be effective unless it is in writing executed by the
party against which such waiver is to be enforced; no waiver shall be deemed or
construed as a further or continuing waiver of any such term, provision,
covenant, representation or warranty (or breach) on any other occasion or as a
waiver of any other term, provision, covenant, representation or warranty (or
of the breach of any other term,  provision, covenant, representation or
warranty) contained in this Agreement on the same or any other occasion.

                 12.6     Counterparts.  For the convenience of the parties,
any number of counterparts hereof may be executed, each such executed
counterpart shall be deemed an original and all such counterparts together
shall constitute one and the same instrument.

                 12.7     Assignment; Binding Nature; No Beneficiaries.  This
Agreement may not be assigned by any party hereto without the written consent
of the other parties; provided, however, that Buyer may assign its rights

obligations.  Subject to the preceding sentence, this Agreement shall be
binding upon, inure to the benefit of, and be enforceable by the parties hereto
and their respective heirs, personal representatives, legatees, successors and
permitted assigns.  Except as otherwise expressly provided in Article XI, this
Agreement shall not confer any rights or remedies upon any Person other than
the parties hereto and their respective heirs, personal representatives,
legatees, successors and permitted assigns.

                 12.8     Headings.  The headings in this Agreement are
inserted for convenience only and shall not constitute a part hereof.

                 12.9     Governing Law; Consent to Jurisdiction.

or alleged breach hereof, each of the parties hereto irrevocably (i) submits to

                                  of such 3-D Common Share Reorganization)

                          warrants, adjusted if necessary in accordance with
                          the Current 3-D Common Share Equivalent at such
                          record date, or the economic equivalent thereof on a
                          per share basis, to the holders of Exchangeable
                          Shares (any such event being herein referred to as a
                          "Rights Offering"), then the Current 3-D Common Share
                          Equivalent then in effect shall be adjusted
                          immediately after such record date by multiplying the

                          record date by the quotient obtained when:

                                  outstanding on such record date and the
                                  number of additional 3-D Common Shares

                                  outstanding on such record date and the
                                  number determined by dividing the aggregate
                                  price of the total number of additional 3-D
                                  Common Shares offered for subscription or

                          of 3-D shall be deemed not to be outstanding for the
                          purpose of any such computation.  If such rights,
                          options or warrants are not so issued or if, at the
                          date of expiry of the rights, options or warrants
                          subject to the Rights Offering, less than all the
                          rights, options or warrants have been exercised, then
                          the Current 3-D Common Share Equivalent shall be

                          then be in effect on the date of expiry if the only
                          rights, options or warrants issued had been those
                          that were exercised, as the case may be;

3.1              A holder of an Exchangeable Share shall be entitled to receive
and the Board of Directors shall, subject to applicable law, declare a dividend
on each Exchangeable Share (a) in the case of a cash dividend declared on the

dividend declared on such number of 3-D Common Shares as is equal to the

Board of Directors on which the Corporation shall have sufficient moneys,
assets or property properly applicable to the payment of such dividends.

                 or senior to the Exchangeable Shares;

provided that the restrictions in subsections 3.5(a), 3.5(b) and 3.5(c) shall
not apply if all dividends on the outstanding Exchangeable Shares corresponding
to dividends declared to date on the 3-D Common Shares shall have been declared
on the Exchangeable Shares and paid in full.

other shares ranking junior to the Exchangeable Shares, an amount per share
equal to (a) the Current Market Price multiplied by the Current 3-D Common
Share Equivalent, in each case determined on the Liquidation Date, which shall
be satisfied in full in respect of all of the Exchangeable Shares held by such
holder by the Corporation causing to be delivered to such holder such whole
number of 3-D Common Shares as is equal to the product obtained by multiplying
the number of such Exchangeable Shares by the Current 3-D Common Share
Equivalent (together with an amount in lieu of any fractional 3-D Common Share
resulting from such calculation payable in accordance with section 10.4), plus
(b) the aggregate of all declared and unpaid dividends on each such
Exchangeable Share up to the Liquidation Date (collectively the "Liquidation
Amount").

4.2              On or promptly after the Liquidation Date, and subject to the
exercise by 3-D  of  the Liquidation Call Right, the Corporation shall cause to
be delivered to the holders of the Exchangeable Shares the Liquidation Amount
for each such Exchangeable Share upon presentation and surrender of the
certificates representing such Exchangeable Shares, together with such other
documents and instruments as may be required to effect a transfer of

thereon by the Corporation or 3-D) and a cheque of the Corporation payable at
par at any branch of the bankers of the Corporation in respect of any
fractional 3-D Common Share and all declared and unpaid dividends comprising
part of the total Liquidation Amount (or, if any of such dividends were payable
in property, such property or property that is the same as or economically
equivalent to such property).  On and after the Liquidation Date, the holders
of the Exchangeable Shares shall cease to be holders of such Exchangeable
Shares and shall not be entitled to exercise any of the rights of holders in
respect thereof. other than the right to receive the total Liquidation Amount
in respect of their Exchangeable Shares, unless payment of the total
Liquidation Amount for such Exchangeable Shares shall not be made upon
presentation and surrender of share certificates in accordance with the
foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Liquidation Amount has been paid in the manner
hereinbefore provided.  The Corporation shall have the right at any time on or
after the Liquidation Date to deposit or cause to be deposited the total
Liquidation Amount in respect of the Exchangeable Shares represented by
certificates that have not at the Liquidation Date been surrendered by the
holders thereof in a custodial account with any chartered bank or trust company
in Canada.  Upon such deposit being made, the rights of the holders of
Exchangeable Shares after such deposit shall be limited to receiving the total
Liquidation Amount (without interest) for such Exchangeable Shares so
deposited, against presentation and surrender of the said certificates held by
them, respectively, in accordance with the foregoing provisions.  Upon such
payment or deposit of the total Liquidation Amount, the holders of the
Exchangeable Shares shall thereafter be considered and deemed for all purposes
to be the holders of the 3-D Common Shares delivered to them.

4.3              After the Corporation has satisfied its obligations to pay the
holders of the Exchangeable Shares the Liquidation Amount per Exchangeable
Share pursuant to section 4.1 of these share provisions, such holders shall not
be entitled to share in any further distribution of the assets of the
Corporation.

                 redeemed by the Corporation; and

         (b)     acknowledging the Retraction Call Right of 3-D to purchase all
                 but not less than all the Retracted Shares directly from the
                 holder and that the Retraction Request shall be deemed to be
                 an irrevocable offer by the holder to sell the Retracted
                 Shares to 3-D in accordance with the Retraction Call Right.

5.2              Subject to the exercise by 3-D of the Retraction Call Right,
upon receipt by the Corporation in the manner specified in section 5.1 hereof
of a certificate or certificates representing the number of Exchangeable Shares
which the holder desires to have the Corporation redeem, together with such
other documents and instruments as may be required pursuant to section 5.1 and
a Retraction Request, the Corporation shall redeem the Retracted Shares
effective at the close of business on the sixth Business Day after the
Retraction Request is received (the "Retraction Date") and shall cause to be
delivered to such holder the total Retraction Price with respect to such
shares.  If only a part of the Exchangeable Shares represented by any
certificate are redeemed (or purchased by 3-D pursuant to the Retraction Call
Right), a new certificate for the balance of such Exchangeable Shares shall be
issued to the holder at the expense of the Corporation.

5.3              Upon receipt by the Corporation of a Retraction Request, the
Corporation shall forthwith notify 3-D thereof.  In order to exercise the
Retraction Call Right, 3-D must deliver a 3-D Call Notice to the Corporation
prior to the expiry of the third Business Day after the receipt by the
Corporation of the Retraction Request in accordance with the provisions of
section 7.2 hereof.  If 3-D does not so notify the Corporation, the Corporation
will notify the holder as soon as possible thereafter that 3-D will not
exercise the Retraction Call Right.  If 3-D delivers the 3-D Call Notice before
the end of such three Business Day period, the Retraction Request shall
thereupon be considered only to be an offer by the holder to sell the Retracted
Shares to 3-D in accordance with the Retraction Call Right.

5.4              If a Retraction Request is received by the Corporation
pursuant to section 5.1 and  3-D has not exercised the Retraction Call Right,
the Corporation shall deliver to the holder of the Retracted Shares, at the
address of the holder recorded in the securities register of the





                                   - 12 -

Corporation for the Exchangeable Shares or at the address specified in the
holder's Retraction Request or by holding for pick-up by the holder at the
registered office of the Corporation, certificates representing the 3-D Common
Shares to be delivered to the holder in payment of the total Retraction Price
for the Retracted Shares (or the portion thereof payable in 3-D Common Shares,
as the case may be) (which shares shall be duly issued as fully paid and
non-assessable and shall be free and clear of any Liens placed thereon by the
Corporation or 3-D) registered in the name of the holder or in such other name
as the holder may request and a cheque of the Corporation payable at par at any
branch of the bankers of the Corporation in payment of the remaining portion,
if any, of the total Retraction Price (or, if any part of the Retraction Price
consists of dividends payable in property, such property or property that is
the same as or economically equivalent to such property), and such delivery of
such certificates and cheque (and property, if any) by the Corporation shall be
deemed to be payment of and shall satisfy and discharge all liability for the
total Retraction Price, to the extent that the same is represented by such
share certificates and cheque (and property, if any), unless such cheque is not
paid on due presentation.

5.5              On and after the close of business on the Retraction Date, the
holder of  the  Retracted Shares shall cease to be a holder of such Retracted
Shares and shall not be entitled to exercise any of the rights of a holder in
respect thereof, other than the right to receive his proportionate part of the
total Retraction Price, unless upon presentation and surrender of certificates
in accordance with the foregoing provisions payment of the total Retraction
Price shall not be made, in which case the rights of such holder shall remain
unaffected until the total Retraction Price has been paid in the manner
hereinbefore provided.  On and after the close of business on the Retraction
Date, provided that presentation and surrender of certificates and payment of
the total Retraction Price has been made in accordance with the foregoing
provisions, the holder of the Retracted Shares so redeemed by the Corporation
shall thereafter be considered and deemed for all purposes to be a holder of
the 3-D Common Shares delivered to it.

5.6              Notwithstanding any other provision of this Article 5, the
Corporation shall not be obligated to redeem Retracted Shares specified by a
holder in a Retraction Request to the extent that such redemption of Retracted
Shares would be contrary to solvency requirements or other provisions of
applicable law.  If the Corporation believes that on any Retraction Date it
would not be permitted by any of such provisions to redeem the Retracted Shares
tendered for redemption on such date, and provided that 3-D shall not have
exercised the Retraction Call Right with respect to the Retracted Shares, the
Corporation shall be obligated to redeem Retracted Shares specified by a holder
in a Retraction Request only to the extent of the maximum number that may be so
redeemed (rounded down to a whole number of shares) as would not be contrary to
such provisions on a pro rata basis and shall notify the holder at least two
Business Days prior to the Retraction Date as to the number of Retracted Shares
which will not be redeemed by the Corporation and the Corporation shall issue
to each holder of Retracted Shares a new certificate, at the expense of the
Corporation, representing the Retracted Shares not redeemed by the Corporation
pursuant to section 5.2 hereof.  The holder of any such Retracted Shares not
redeemed by the Corporation pursuant to section 5.2 of these share provisions
as a result of solvency requirements of applicable law shall be deemed by
giving the Retraction Request to require 3-D to purchase such Retracted Shares
from such holder pursuant to the Exchange Right (as defined in the Share
Exchange Agreement).

                       REDEMPTION OF EXCHANGEABLE SHARES

6.1              Subject to applicable law and if 3-D does not exercise the
Redemption Call Right, the Corporation shall on the Automatic Redemption Date
redeem the whole of the then outstanding Exchangeable Shares for an amount per
share equal to (a) the Current Market Price multiplied by the Current 3-D
Common Share Equivalent, in each case determined on the Automatic Redemption
Date, which shall be satisfied in full in respect of all of the Exchangeable
Shares held by each holder of Exchangeable Shares by the Corporation causing to
be delivered to such holder such whole number of 3-D Common Shares as is equal
to the product obtained by multiplying the number of such Exchangeable Shares
by the Current 3-D Common Share Equivalent (together with an amount in lieu of
any fractional 3-D Common Share resulting from such calculation payable in
accordance with section 10.4), plus (b) the aggregate of all declared and
unpaid dividends thereon up to the Automatic Redemption Date (collectively the
"Redemption Price").

6.2              On or after the Automatic Redemption Date and subject to the
exercise by 3-D of the Redemption Call Right, the Corporation shall cause to be
delivered to the holders of the Exchangeable Shares the Redemption Price for
each such Exchangeable Share upon presentation and surrender at the registered
office of the Corporation (or at such other place that may be specified by the
Corporation in a notice to the holders of Exchangeable Shares) of the
certificates representing such Exchangeable Shares, together with such other
documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the CBCA and the by-laws of the Corporation and such
additional documents and instruments as the Corporation may reasonably require.
Payment of the total Redemption Price for such Exchangeable Shares shall be
made by delivery to each holder, at the address of the holder recorded in the
securities register of the Corporation or by holding for pick up by the holder
at the registered office of the Corporation (or at such other place that may be
specified by the Corporation in a notice to the holders of Exchangeable
Shares), of certificates representing the 3-D Common Shares to be delivered to
the holder in payment of the Redemption Price (or the portion thereof payable
in 3-D Common Shares, as the case may be) (which shares shall be duly issued as
fully paid and non-assessable and shall be free and clear of any Liens placed
thereon by the Corporation or  3-D) and a cheque of the Corporation payable at
par at any branch of the bankers of the Corporation in respect of any
fractional 3-D Common Share and all declared and unpaid dividends comprising
part of the total Redemption Price (or, if any of such dividends are payable in
property, such property).  On and after the Automatic Redemption Date, the
holders of the Exchangeable Shares called for redemption shall cease to be
holders of such Exchangeable Shares and shall not be entitled to exercise any
of the rights of holders in respect thereof, other than the right to receive
the total Redemption Price for their Exchangeable Shares, unless payment of the
total Redemption Price for such Exchangeable Shares shall not be made upon
presentation and surrender of certificates in accordance with the foregoing
provisions, in which case the rights of the holders shall remain unaffected
until the total Redemption Price has been paid in the manner hereinbefore
provided.  The Corporation shall have the right at any time to deposit or cause
to be deposited the total Redemption Price of the Exchangeable Shares so called
for redemption, or of such of the said Exchangeable Shares represented by
certificates that have





                                   - 14 -
<PAGE>   63
not at the date of such deposit been surrendered by the holders thereof in
connection with such redemption, in a custodial account with any chartered bank
or trust company in Canada named in such notice.  Upon the later of such
deposit being made and the Automatic Redemption Date, the Exchangeable Shares
in respect whereof such deposit shall have been made shall be redeemed and the
rights of the holders thereof after such deposit or Automatic Redemption Date,
as the case may be, shall be limited to receiving the total Redemption Price
for such Exchangeable Shares so deposited, against presentation and surrender
of the said certificates held by them, respectively, in accordance with the
foregoing provisions.  Upon such payment or deposit of the total Redemption
Price, the holders of the Exchangeable Shares shall thereafter be considered
and deemed for all purposes to be holders of the 3-D Common Shares delivered to
them.


                                   ARTICLE 7

           CERTAIN CALL RIGHTS OF 3-D TO ACQUIRE EXCHANGEABLE SHARES

7.1              3-D shall have the overriding right (the "Retraction Call
Right"), notwithstanding the proposed redemption of Retracted Shares by the
Corporation on a Retraction Date, to purchase from the holder of the Retracted
Shares on the Retraction Date the Retracted Shares upon payment by 3-D to the
holder of an amount per share equal to (a) the Current Market Price multiplied
by the Current 3-D Common Share Equivalent, in each case determined on the
Retraction Date, which shall be satisfied in full in respect of the Retracted
Shares by causing to be delivered to such holder such whole number of 3-D
Common Shares as is equal to the product obtained by multiplying the number of
Retracted Shares by the Current 3-D Common Share Equivalent (together with an
amount in lieu of any fractional 3-D Common Share resulting from such
calculation payable in accordance with section 10.4), plus (b) the aggregate of
all dividends declared and unpaid on such Retracted Share (collectively the
"Retraction Call Purchase Price").  In the event of the exercise of the
Retraction Call Right by 3-D, the holder of the Retracted Shares shall be
obligated to sell to 3-D, and 3-D shall be obligated to purchase, the Retracted
Shares on the Retraction Date upon payment by 3-D to such holder of the
Retraction Call Purchase Price for each Retracted Share.

7.2              In order to exercise the Retraction Call Right, 3-D must
notify the  Corporation  in writing of its determination to do so (the "3-D
Call Notice") prior to the expiry of the third  Business Day after the receipt
by the Corporation of the Retraction Request.  If 3-D delivers the 3-D Call
Notice before the end of such three Business Day period, the Retraction Request
shall thereupon be considered only to be an offer by the holder to sell the
Retracted Shares to 3-D in accordance with the Retraction Call Right.  In such
event, the Corporation shall not redeem the Retracted Shares and 3-D shall
purchase from such holder and such holder shall sell to 3-D on the Retraction
Date the Retracted Shares for the Retraction Call Purchase Price for each
Retracted Share.

7.3              For the purposes of completing a purchase of the Retracted
Shares pursuant to  the Retraction Call Right, 3-D shall deposit with the
Corporation, on or before the Retraction Date (or, where the holder of the
Retracted Shares is a non-resident of Canada, as soon as





                                   - 15 -
<PAGE>   64
practicable thereafter), certificates representing the 3-D Common Shares to be
delivered to the holder of the Retracted Shares in payment of the total
Retraction Call Purchase Price for the Retracted Shares (or the portion thereof
payable in 3-D Common Shares, as the case may be) and a cheque in the amount of
the remaining portion, if any, of the total Retraction Call Purchase Price (or,
if any part of the Retraction Call Purchase Price consists of dividends payable
in property, such property or property that is the same as or economically
equivalent to such property).  Provided that such total Retraction Call
Purchase Price has been so deposited with the Corporation, the closing of the
purchase and sale of the Retracted Shares pursuant to the Retraction Call Right
shall be deemed to have occurred as of the close of business on the Retraction
Date and, for greater certainty, no redemption by the Corporation of such
Retracted Shares shall take place on the Retraction Date. 3-D shall cause the
Corporation to deliver to the holder of the Retracted Shares, at the address of
such holder recorded in the securities register of the Corporation for the
Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick-up by the holder at the office of the
Corporation to which the Retraction Request was delivered, in payment of such
total Retraction Call Purchase Price, certificates representing the 3-D Common
Shares to be delivered in respect of such payment (which shares shall be duly
issued as fully paid and non-assessable and shall be free and clear of any
Liens placed thereon by the Corporation or 3-D) registered in the name of the
holder or in such other name as the holder may request in payment of such and,
if applicable, a cheque of 3-D payable at par and in Canadian dollars at any
branch of the bankers of 3-D or the Corporation in Canada (or, if any part of
the Retraction Call Purchase Price consists of dividends payable in property,
such property or property that is the same as or economically equivalent to
such property), and such delivery of such certificates and cheque (and
property, if any) to the holder on behalf of 3-D by the Corporation shall be
deemed to be payment of and shall satisfy and discharge all liability for the
total Retraction Call Purchase Price to the extent that the same is represented
by such share certificates and cheque (and property, if any), unless such
cheque is not paid on due presentation.  On and after the close of business on
the Retraction Date, the holder of the Retracted Shares shall cease to be a
holder of such Retracted Shares and shall not be entitled to exercise any of
the rights of a holder in respect thereof, other than the right to receive the
Retraction Call Purchase Price, unless upon presentation and surrender of
certificates in accordance with the foregoing provisions, payment of the total
Retraction Call Purchase Price shall not be made, in which case the rights of
such holder shall remain unaffected until the total Retraction Call Purchase
Price has been paid in the manner hereinbefore provided.  On and after the
close of business on the Retraction Date, provided that presentation and
surrender of certificates and payment of the total Retraction Call Purchase
Price has been made in accordance with the foregoing provisions, the holder of
the Retracted Shares so purchased by 3-D shall thereafter be considered and
deemed for all purposes to be a holder of the 3-D Common Shares delivered to
such holder.

7.4              3-D shall have the overriding right (the "Liquidation Call
Right"), in the  event  of and notwithstanding the proposed liquidation,
dissolution or winding-up of the Corporation, to purchase from all but not less
than all of the holders (other than 3-D and its Affiliates) of Exchangeable
Shares on the Liquidation Date all but not less than all of the Exchangeable
Shares held by each such holder on payment by 3-D of an amount per share equal
to (a) the Current Market Price multiplied by the Current 3-D Common Share
Equivalent, in each case determined on the Liquidation Date, which shall be
satisfied in full in respect of all of the Exchangeable





                                   - 16 -
<PAGE>   65
Shares held by such holder by 3-D causing to be delivered to such holder such
whole number of 3-D Common Shares as is equal to the product obtained by
multiplying the number of such Exchangeable Shares by the Current 3-D Common
Share Equivalent (together with an amount in lieu of any fractional 3-D Common
Share resulting from such calculation payable in accordance with section 10.4),
plus (b) the aggregate of all dividends declared and unpaid on such
Exchangeable Share up to the Liquidation Date (collectively the "Liquidation
Call Purchase Price").  In the event of the exercise of the Liquidation Call
Right by 3-D, each holder shall be obligated to sell all the Exchangeable
Shares held by the holder to 3-D on the Liquidation Date on payment by 3-D to
the holder of the Liquidation Call Purchase Price for each such share.

7.5              To exercise the Liquidation Call Right, 3-D must notify the
Corporation of 3-D's intention to exercise such right at least 10 days before
the Liquidation Date in the case of a voluntary liquidation, dissolution or
winding up of the Corporation and at least three Business Days before the
Liquidation Date in the case of an involuntary liquidation, dissolution or
winding up of the Corporation.  The Corporation will notify the holders of
Exchangeable Shares as to whether or not 3-D has exercised the Liquidation Call
Right forthwith after the expiry of the date by which the same may be exercised
by 3-D.  If 3-D exercises the Liquidation Call Right, on the Liquidation Date
3-D will purchase and the holders will sell all of the Exchangeable Shares then
outstanding for a price per share equal to the Liquidation Call Purchase Price.

7.6              For the purposes of completing the purchase of  the
Exchangeable  Shares  pursuant  to the Liquidation Call Right, 3-D shall
deposit with the Corporation, on or before the Liquidation Date (or where the
holder of the Exchangeable Shares is a non-resident of Canada. as soon as
practicable thereafter, certificates representing the aggregate number of 3-D
Common Shares deliverable by 3-D (which shares shall be duly issued as fully
paid and non-assessable and shall be free and clear of any Liens placed thereon
by the Corporation or 3-D) in payment of the total Liquidation Call Purchase
Price (or the portion thereof payable in 3-D Common Shares, as the case may be)
and a cheque or cheques in the amount of the remaining portion, if any, of the
total Liquidation Call Purchase Price (or, if any part of the Liquidation Call
Purchase Price consists of dividends payable in property, such property or
property that is the same as or economically equivalent to such property).
Provided that such total Liquidation Call Purchase Price has been so deposited
with the Corporation, on and after the Liquidation Date the rights of each
holder of Exchangeable Shares will be limited to receiving such holder's
proportionate part of the total Liquidation Call Purchase Price payable by 3-D
upon presentation and surrender by the holder of certificates representing the
Exchangeable Shares held by such holder and the holder shall on and after the
Liquidation Date be considered and deemed for all purposes to be the holder of
the 3-D Common Shares delivered to it.  Upon surrender to the Corporation of a
certificate or certificates representing Exchangeable Shares, together with
such other documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the CBCA and the articles and by-laws of the
Corporation and such additional documents and instruments as the Corporation
may reasonably require, the holder of such surrendered certificate or
certificates shall be entitled to receive in exchange therefor, and the
Corporation on behalf of 3-D shall deliver to such holder, certificates
representing the 3-D Common Shares to which the holder is entitled and a cheque
or cheques of 3-D payable at par and in Canadian dollars at any branch of the
bankers of 3-D or of the Corporation in Canada in payment of the





                                   - 17 -
<PAGE>   66
remaining portion, if any, of the total Liquidation Call Purchase Price (or, if
any part of the Liquidation Call Purchase Price consists of dividends payable
in property, such property or property that is the same as or economically
equivalent to such property).  If 3-D does not exercise the Liquidation Call
Right in the manner described above, on the Liquidation Date the holders of the
Exchangeable Shares will be entitled to receive in exchange therefor the
Liquidation Amount otherwise payable by the Corporation in connection with the
liquidation, dissolution or winding-up of the Corporation pursuant to sections
4.1 to 4.3 hereof.

7.7              3-D shall have the overriding right (the "Redemption Call
Right"), not- withstanding the proposed redemption of the Exchangeable Shares
by the Corporation on the Automatic Redemption Date, to purchase from all but
not less than all of the holders (other than 3-D or its Affiliates) of
Exchangeable Shares on the Automatic Redemption Date all but not less than all
of the Exchangeable Shares held by each such holder on payment by 3-D to the
holder of an amount per share equal to (a) the Current Market Price multiplied
by the Current 3-D Common Share Equivalent, in each case determined on the
Automatic Redemption Date, which shall be satisfied in full in respect of all
of the Exchangeable Shares held by such holder by causing to be delivered to
such holder such number of 3-D Common Shares as is equal to the product
obtained by multiplying the number of such Exchangeable Shares by the Current
3-D Common Share Equivalent (together with an amount in lieu of any fractional
3-D Common Share resulting from such calculation payable in accordance with
section 10.4), plus (b) the aggregate of all dividends declared and unpaid on
such Exchangeable Share (collectively the "Redemption Call Purchase Price").
In the event of the exercise of the Redemption Call Right by 3-D, each holder
shall be obligated to sell to 3-D, and 3-D shall be obligated to purchase, all
the Exchangeable Shares held by the holder on the Automatic Redemption Date on
payment by 3-D to the holder of the Redemption Call Purchase Price for each
such share.

7.8              To exercise the Redemption Call Right, 3-D must notify the
Corporation, as agent for the holders of the Exchangeable Shares, and the
Corporation of 3-D's intention to exercise such right at least 10 days before
the Automatic Redemption Date.  The Corporation will notify the holders of the
Exchangeable Shares as to whether or not 3-D has exercised the Redemption Call
Right forthwith after the date by which the same may be exercised by 3-D.  If
3-D exercises the Redemption Call Right, on the Automatic Redemption Date 3-D
will purchase and the holders will sell all of the Exchangeable Shares then
outstanding for a price per share equal to the Redemption Call Purchase Price.

7.9              For the purposes of completing the purchase of the
Exchangeable Shares  pursuant  to the Redemption Call Right, 3-D shall deposit
with the Corporation, on or before the Automatic Redemption Date (or, where the
holder of the Exchangeable Shares is a non-resident of Canada, as soon as
practicable thereafter), certificates representing the aggregate number of 3-D
Common Shares deliverable by 3-D (which shares shall be duly issued as fully
paid and non-assessable and shall be free and clear of any Liens placed thereon
by the Corporation or 3-D) in payment of the total Redemption Call Purchase
Price (or the portion thereof payable in 3-D Common Shares, as the case may be)
and a cheque or cheques in the amount of the remaining portion, if any, of the
total Redemption Call Purchase Price (or, if part of the Redemption Call
Purchase Price consists of dividends payable in property, such property or
property the same as or economically equivalent to such property).  Provided
that such total





                                   - 18 -
<PAGE>   67
Redemption Call Purchase Price has been so deposited with the Corporation, on
and after the Automatic Redemption Date the rights of each holder of
Exchangeable Shares will be limited to receiving such holder's proportionate
part of the total Redemption Call Purchase Price payable by 3-D upon
presentation and surrender by the holder of certificates representing the
Exchangeable Shares held by such holder and the holder shall on and after the
Automatic Redemption Date be considered and deemed for all purposes to be the
holder of the 3-D Common Shares delivered to such holder.  Upon surrender to
the Corporation of a certificate or certificates representing Exchangeable
Shares, together with such other documents and instruments as may be required
to effect a transfer of Exchangeable Shares under the CBCA and the articles and
by-laws of the Corporation and such additional documents and instruments as the
Corporation may reasonably require, the holder of such surrendered certificate
or certificates shall be entitled to receive in exchange therefor, and the
Corporation on behalf of 3-D shall deliver to such holder, certificates
representing the 3-D Common Shares to which the holder is entitled and a cheque
or cheques of 3-D payable at par and in Canadian dollars at any branch of the
bankers of 3-D or of the Corporation in Canada in payment of the remaining
portion, if any, of the total Redemption Call Purchase Price (or, if part of
the Redemption Call Purchase Price consists of dividends payable in property,
such property or property the same as or economically equivalent to such
property).  If 3-D does not exercise the Redemption Call Right in the manner
described above, on the Automatic Redemption Date the holders of the
Exchangeable Shares will be entitled to receive in exchange therefor the
redemption price otherwise payable by the Corporation in connection with the
redemption of the Exchangeable Shares pursuant to sections 6.1 and 6.2 hereof.

7.10             The Retraction Call Right, the Liquidation  Call  Right and
the Redemption Call  Right are granted to 3-D by the holders of Exchangeable
Shares in consideration of the grant by 3-D of the Automatic Exchange Rights
and the Exchange Right (as such terms are respectively defined in the Share
Exchange Agreement) to the holders of Exchangeable Shares (other than 3-D and
its Affiliates).

                 ECONOMIC EQUIVALENCE; CHANGES RELATING TO 3-D

10.1             The Board of Directors shall determine, in good faith and in
its sole discretion  (with the assistance of such reputable and qualified
independent financial advisors and/or other experts as the Board of Directors
may require), economic equivalence for the purposes of any provision herein
that requires such a determination and each such determination shall be
conclusive and binding on 3-D and all holders of Exchangeable Shares where
applicable.

10.2             If at any time there is a capital reorganization of 3-D that
is not provided for in subsection 1.1(o) or a consolidation, merger,
arrangement or amalgamation (statutory or otherwise) of 3-D with or into
another entity (any such event being called a "Capital Reorganization"), any
holder of Exchangeable Shares whose Exchangeable Shares have not been exchanged
or automatically exchanged for 3-D Common Shares in accordance with the
provisions hereof or the provisions of the Share Exchange Agreement on or
before the record date for such Capital Reorganization shall be entitled to
receive and shall accept, upon any such exchange occurring pursuant to the
provisions hereof or the Share Exchange Agreement at any time after the record
date for such Capital Reorganization, in lieu of the 3-D Common Shares that he
would otherwise have been entitled to receive pursuant to the provisions hereof
or the Share Exchange Agreement, the number of shares or other securities of
3-D or of the body corporate resulting, surviving or continuing from the
Capital Reorganization, or other property, that such holder would have been
entitled to receive as a result of such Capital Reorganization

if, on the record date, he had been the registered holder of the number of 3-D
Common Shares to which he was then entitled upon any exchange of his
Exchangeable Shares into 3-D Common Shares in accordance with the provisions
hereof or the Share Exchange Agreement, subject to adjustment thereafter in the
same manner, as nearly as may be possible, as is provided for in subsection
1.1(o); provided that in the event that all the outstanding Exchangeable Shares
are not exchanged or automatically exchanged for 3-D Common Shares in
accordance with the provisions hereof or the Share Exchange Agreement on or
before the record date for such Capital Reorganization such Capital
Reorganization shall not be carried into effect unless all necessary steps
shall have been taken so that each holder of Exchangeable Shares shall
thereafter be entitled to receive upon any exchange of his Exchangeable Shares
pursuant to the provisions hereof or the Share Exchange Agreement, such number
of shares or other securities of 3-D or of the body corporate resulting,
surviving or continuing from the Capital Reorganization, or other property.

10.3             In the case of any reclassification of, or other change in,
the outstanding 3-D Common Shares other than (i) a 3-D Common Share
Reorganization, (ii) a Capital Reorganization, or (iii) an Automatic Exchange
Event (as defined in the Share Exchange Agreement), such changes shall be made
in the rights attaching to the Exchangeable Shares, without any action on the
part of the Corporation or the holders of the Exchangeable Shares to the extent
permitted by applicable law, effective immediately following the record date
for such reclassification or other change, to the extent necessary to ensure
that holders of Exchangeable Shares shall be entitled to receive, upon the
occurrence at any time after such record date of any event whereby they would
receive 3-D Common Shares pursuant to the provisions hereof or the Share
Exchange Agreement, such shares, securities or rights as they would have
received if their Exchangeable Shares had been exchanged for 3-D Common Shares
pursuant to the provisions hereof or the Share Exchange Agreement immediately
prior to such record date, subject to adjustment thereafter in the same manner,
as nearly as may be possible, as is provided for in subsection 1.1(o).

10.4             No certificates or scrip representing fractional 3-D Common
Shares shall be delivered to holders of Exchangeable Shares pursuant to the
provisions hereof.  In lieu of any such fractional security, each person
entitled to a fractional interest in a 3-D Common Share will receive an amount
of cash (rounded to the nearest whole cent), without interest, equal to the
Canadian Dollar Equivalent as of the second Business Day prior to the relevant
date of delivery of certificates representing 3-D Common Shares (the
"Fractional Share Calculation Date") of the product of (i) such fraction,
multiplied by (ii) the closing sale price of 3-D Common Shares as reported on
NASDAQ on the Fractional Share Calculation Date.

concerning seismic data, marketing strategy, technology, techniques and
know-how, customer specifications and customer lists, cost figures, budgets,
sales forecasts and business plans.  The Employee agrees that the disclosure of
any such trade secrets or information could be harmful to the interests of the
Company, 3-D or such subsidiaries and that, during the Employee's employment by
the Company or its subsidiaries, the Employee will take appropriate caution to
safeguard such trade secrets and information, and will not during the Term or
thereafter use, disclose, divulge or publish any such trade secrets or
information except as required by law or as the Employee's duties during the
Employee's employment by the Company or its subsidiaries may require or as the
Company may in writing specifically consent.

         8.5  Proprietary Information.  The Employee recognizes and
acknowledges that all documents, manuals, letters, notebooks, reports, records,
computer programs or data banks and other evidences of trade secrets and other
confidential or proprietary information of the Company, 3-D and their
respective subsidiaries, including copies thereof, whether prepared by the
Employee or others, are the sole property of and belong exclusively to the
Company, 3-D and their respective subsidiaries, and agrees that, during the

under no circumstances remove any such material for use outside of his offices
except in connection with the business of the Company during the course of the
Employee's employment.  In the event of

the termination of this Agreement for any reason whatsoever, the Employee shall
immediately return to the Company any and all documents, manuals, letters,
notebooks, records, computer programs or data banks or other evidence of trade
secrets and other confidential or proprietary information of the Company, 3-D

property of the Company, 3-D or any of their respective subsidiaries.

         8.6  Remedies.  The Employee further agrees that in the event of a
breach or threatened breach of any of the covenants contained in this Section
8, the Company's remedy at law is likely to be inadequate and that accordingly
the Company will be entitled to obtain an injunction or other equitable relief
with regard thereto without proving damages or that damages would not
constitute an adequate remedy.  If the final judgment of a court of competent
jurisdiction declares that any term or provision of this Section 8 is invalid
or unenforceable, the parties hereto agree that the court making the
determination of invalidity or unenforceability shall have the power to, and is
hereby directed to, reduce the scope, duration or area of the term or
provision, to delete specific words or phrases, or to replace any invalid or
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid
and unenforceable term or provision, and this Agreement shall be enforceable as
so modified.

8.7  Survival.  The provisions of this Section 8 shall survive

                                     -5-
<PAGE>   93
any way, directly or indirectly, as an agent, employee, officer, director,
stockholder, partner or otherwise of any corporation, partnership or other
venture or enterprise compete with the Company, 3-D or any of their respective
subsidiaries in the provision of seismic data acquisition or analysis services
or any services related thereto (a "Competing Business"), other than pursuant
hereto.

         8.2  Non-Solicitation Covenant.  During the Term and for a period of
one (1) year after the termination of this Agreement for any reason whatsoever,
the Employee shall not solicit, sell to or contract with, on behalf of the

Term and for a period of one (1) year after the termination of this Agreement
for any reason whatsoever, the Employee shall not solicit for employment any
sales, engineering or other technical or management employee who was employed
by the Company or any of its subsidiaries during the Term.

         8.4  Non-Disclosure Covenant.  The Employee recognizes and
acknowledges that, in the course of his employment, the Employee will have
access to trade secrets and other confidential or proprietary information of
the Company, 3-D and their respective subsidiaries, including, but not limited
to, information





                                     -6-
<PAGE>   94
concerning seismic data, marketing strategy, technology, techniques and
know-how, customer specifications and customer lists, cost figures, budgets,
sales forecasts and business plans.  The Employee agrees that the disclosure of
any such trade secrets or information could be harmful to the interests of the
Company, 3-D or such subsidiaries and that, during the Employee's employment by
the Company or its subsidiaries, the Employee will take appropriate caution to
safeguard such trade secrets and information, and will not during the Term or
thereafter use, disclose, divulge or publish any such trade secrets or
information except as required by law or as the Employee's duties during the
Employee's employment by the Company or its subsidiaries may require or as the
Company may in writing specifically consent.

         8.5  Proprietary Information.  The Employee recognizes and
acknowledges that all documents, manuals, letters, notebooks, reports, records,
computer programs or data banks and other evidences of trade secrets and other
confidential or proprietary information of the Company, 3-D and their
respective subsidiaries, including copies thereof, whether prepared by the
Employee or others, are the sole property of and belong exclusively to the
Company, 3-D and their respective subsidiaries, and agrees that, during the
Employee's employment by the Company or its subsidiaries, the Employee will
under no circumstances remove any such material for use outside of his offices
except in connection with the business of the Company during the course of the
Employee's employment.  In the event of





                                     -7-
<PAGE>   95
the termination of this Agreement for any reason whatsoever, the Employee shall
immediately return to the Company any and all documents, manuals, letters,
notebooks, records, computer programs or data banks or other evidence of trade
secrets and other confidential or proprietary information of the Company, 3-D
and their respective subsidiaries, including copies thereof, which are the
property of the Company, 3-D or any of their respective subsidiaries.

         8.6  Remedies.  The Employee further agrees that in the event of a
breach or threatened breach of any of the covenants contained in this Section
8, the Company's remedy at law is likely to be inadequate and that accordingly
the Company will be entitled to obtain an injunction or other equitable relief
with regard thereto without proving damages or that damages would not
constitute an adequate remedy.  If the final judgment of a court of competent
jurisdiction declares that any term or provision of this Section 8 is invalid
or unenforceable, the parties hereto agree that the court making the
determination of invalidity or unenforceability shall have the power to, and is
hereby directed to, reduce the scope, duration or area of the term or
provision, to delete specific words or phrases, or to replace any invalid or
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid
and unenforceable term or provision, and this Agreement shall be enforceable as
so modified.

         8.7  Survival.  The provisions of this Section 8 shall





                                     -8-

                                ESCROW AGREEMENT

                 ESCROW AGREEMENT (this "Agreement") dated as of [_________ __,
1996] among 3-D Geophysical, Inc., a Delaware corporation ("3-D"), 3-D
Geophysical of Canada, Inc., a Canadian corporation ("Buyer"), D.E. Janveau
("DJ"), Gladys Mueller ("GM") and W.G. Mueller ("WGM"; DJ, GM and WGM being
sometimes referred to individually as a "Seller" and collectively as
"Sellers")and Montreal Trust Company of Canada, a financial institution
incorporated under the laws of Canada (the "Escrow Agent").

                 WHEREAS, 3-D, Buyer and Sellers have entered into a Stock
Purchase Agreement dated as of December 10, 1996 (the "Stock Purchase
Agreement") providing for the sale to Buyer by Sellers of all of the issued and
outstanding capital stock of J.R.S.  Exploration Company Limited, an Alberta
corporation ("Company").  Capitalized terms not otherwise defined herein shall
have the same meaning as defined in the Stock Purchase Agreement; and

                 WHEREAS, Section 3.2(a)(viii) of the Stock Purchase Agreement
provides for the deposit by Sellers with the Escrow Agent of a certificate or
certificates, registered in the name of Sellers, together with appropriate
stock powers duly executed in blank, for 50% of the aggregate number of Buyer's
Shares issued to DJ, GM and WGM pursuant to the provisions of Section 2.1(b) of
the Stock Purchase Agreement (the deposits described in this Whereas clause,
together with any funds deposited with the Escrow Agent pursuant to Section
2(c), being referred to as the "Escrow Fund");

                 NOW THEREFORE, in consideration of the mutual covenants and
agreements contained herein and in the Stock Purchase Agreement, the parties
hereto hereby agree as follows:

                 1.       Appointment.  Montreal Trust Company of Canada is
hereby appointed Escrow Agent to accept, retain and dispose of the Escrow Fund
in accordance with the provisions of this Agreement.  The Escrow Agent hereby
accepts such appointment and agrees to accept, retain and dispose of the Escrow
Fund in accordance with the provisions of this Agreement.

                 2.       Deposit of Escrow Fund; Substitution.  (a)  Each
Seller hereby deposits with the Escrow Agent, and the Escrow Agent hereby
acknowledges receipt of, a certificate or certificates registered in the name
of such Seller and representing 50% of the aggregate number of Buyer's Shares
issued to such Seller pursuant to the provisions of Section 2.1(b) of the Stock
Purchase Agreement (the "Stock Portion of the Escrow Fund") in full
satisfaction of such Seller's obligations to make
<PAGE>   103
deposits with the Escrow Agent under Section 3.2(a)(viii) of the Stock Purchase
Agreement.

                 (b)      Schedule I attached hereto sets forth the name of 
each Seller and sets forth the number of Buyer's Shares to be deposited into
the Escrow Fund by such Seller pursuant to the terms of Section 3.2(a)(viii) of
the Stock Purchase Agreement.

                 (c)      From time to time during the Escrow Term (as
hereinafter defined), each Seller has the right to substitute all or any
portion of the Buyer's Shares forming a part of the Escrow Fund and deposited
with the Escrow Agent by such Seller pursuant to this Agreement, by depositing
with the Escrow Agent cash in an amount equal to the Common Stock Market Price
for each Buyer's Share substituted pursuant to the provisions of this Section
2(c).  Not less than ten (10) days prior to the date a Seller wishes to effect
the foregoing described substitution, he shall notify in writing the Escrow
Agent and Buyer that he wishes to substitute such Buyer's Shares ("Substituted
Stock") for cash on such date ("Substitution Date").  On the Substitution Date,
(i) the Seller shall deliver to the Escrow Agent a certified or official bank
check payable to the order of the Escrow Agent in an amount equal to the
product of (x) the Common Stock Market Price and (y) the number of shares of
Substituted Stock; and (ii) the Escrow Agent shall deliver or cause to be
delivered to such Seller, as the case may be, a stock certificate registered in
the name of such Seller, as the case may be, representing the number of shares
of Substituted Stock.  All deposits of cash made pursuant to this Section 2(c)
shall be accepted by the Escrow Agent, retained as part of the Escrow Fund and
disposed of by it in accordance with the provisions of this Agreement (such
cash being referred to as the "Cash Portion of the Escrow Fund").

                 (d)      Each Seller shall only have the right of substitution
described in Section 2(c) with respect to a number of Buyer's Shares equal to
the number of Buyer's Shares of such Seller initially deposited by such Seller
pursuant to Section 2(a) (subject to appropriate adjustment for any stock
dividend on or split-up or combination of the Buyer's Shares).

                 3.       Duty of Care, Investments.  (a)  The Escrow Agent
shall hold and safeguard the Escrow Fund and shall treat the Escrow Fund as a
trust fund in accordance with the provisions of this Agreement.  The Escrow
Agent shall invest the Cash Portion of the Escrow Fund in money market
obligations, certificates of deposit or other short-term interest bearing
securities.

                 (b)      Any (i) interest, gains on the sale of securities or
other income received by the Escrow Agent in respect of the Cash Portion of the
Escrow Fund, reduced by any taxes, brokerage fees and other expenses incurred
in connection with the investment of the Cash Portion of the Escrow Fund (the
"Net Gain"), and (ii) Buyer's Shares with respect to the Stock Portion of the
Escrow Fund as a result of any stock dividend, split-up or






                                     -2-
<PAGE>   104
combination, or into which the Buyer's Shares shall be converted or exchanged
as a result of any merger, reclassification or reorganization, shall constitute
a part of the Escrow Fund and shall be retained and disposed of in accordance
with the provisions of this Agreement.

                 4.       Disbursement of Escrow Fund.  The following
provisions shall govern the Escrow Fund:

                 (a)      The Escrow Fund shall be retained by the Escrow Agent
until the first anniversary of the Closing Date (the "Escrow Term").

                 (b)      In order to make a claim against the Escrow Fund
(which claim shall, if appropriate, include interest thereon at the rate equal
to the rate 3-D then pays on its long-term debt), Buyer shall deliver to the
Escrow Agent either (i) a certificate signed by (A) an officer of Buyer and (B)
the Sellers' Representative (as defined in Section 11), as the representative
of the Sellers, stating in reasonable detail the factual and legal basis for
and the amount of such claim (a "Certificate of Claim Resolution"), or (ii) a
copy of a final, non-appealable order of a court of competent jurisdiction (a
"Final Order") ordering the Escrow Agent to pay an amount specified in such
Final Order to Buyer.  Upon receipt of a Certificate of Claim Resolution or a
Final Order, the Escrow Agent shall as soon as practicable, and in any event
within ten (10) days, thereafter pay the amount set forth in such Certificate
of Claim Resolution or Final Order (the "Claim Amount") to Buyer by delivering
or causing to be delivered to Buyer a certificate registered in the name of
Buyer for a number of whole Buyer's Shares equal to the Claim Amount divided by
the Common Stock Market Price; provided, however, that, if any Seller has made
a substitution pursuant to Section 2(c), the Escrow Agent shall instead
deliver, or cause to be delivered, to Buyer (x) a check payable to the order of
Buyer in an amount equal to the product of the Cash Percentage (as hereinafter
defined) and the Claim Amount (plus the Net Gain on such amount from the
respective date(s) of substitution pursuant to Section 2(c)), and (y) a
certificate registered in the name of Buyer for a number of whole Buyer's
Shares equal to the product of the Stock Percentage (as hereinafter defined)
and the Claim Amount, divided by the Common Stock Market Price.  "Cash
Percentage" means a fraction, where the numerator is the value of the Cash
Portion of the Escrow Fund (excluding any Net Gain) on the day before the date
payment is to be made pursuant to this Section 4(b), determined by the Escrow
Agent in its absolute discretion ("Cash Value"), and the denominator is the
Cash Value plus the product of (x) the number of Buyer's Shares constituting
the Stock Portion of the Escrow Fund on the day before the date payment is to
be made pursuant to this Section 4(b), and (y) the Common Stock Market Price.
"Stock Percentage" means the percentage equal to 100% minus the Cash
Percentage.

<PAGE>   105
                 (c)      As soon as practicable after the expiration of the
Escrow Term, and in any event within thirty (30) days thereafter:

                          (i)     If there is not then unresolved a Notice of a
         Pending Claim (as defined below) from Buyer, the Escrow Agent shall
         automatically deliver, or cause to be delivered, (A) to each Seller
         who has not substituted pursuant to Section 2(c), a certificate
         registered in the name of such Seller representing a whole number of
         Buyer's Shares equal to the product of (x) the Seller's Stock
         Percentage (as hereinafter defined) of such Seller, and (y) the number
         Buyer's Shares then held by the Escrow Agent as part of the Escrow
         Fund; and (B) to each Seller who has substituted pursuant to Section
         2(c), an official bank check payable to the order of such Seller in an
         amount equal to the sum of (A) product of (x) Seller's Cash Percentage
         (as hereinafter defined) of such Seller, and (y) the Cash Portion of
         the Escrow Fund (excluding any Net Gain) then held by the Escrow Agent
         and (B) the Net Gain allocable to such Seller, as determined by the
         Escrow Agent, whose determination shall be final and binding.  Upon
         such deliveries, this Escrow Agreement shall terminate.  Seller's
         Stock Percentage means the percentage obtained by dividing (x) the
         excess of (A) number of Buyer's Shares initially deposited into the
         Escrow Fund in respect of such Seller pursuant to the terms of Section
         3.1(a)(viii) of the Stock Purchase Agreement, over (B) the number of
         shares of Substituted Stock of such Seller (in each case appropriately
         adjusted for stock splits or combinations of the Buyer Common Stock)
         by (y) the total number of Buyer's Shares then constituting the Stock
         Portion of the Escrow Fund.  Seller's Cash Percentage means the
         percentage obtained by dividing the amount of cash such Seller has
         deposited pursuant to Section 2(c) by the total amount of cash all
         such Sellers have deposited pursuant to Section 2(c).

                          (ii)    If there is then unresolved one or more
         written notices (a "Notice of a Pending Claim"), signed by an officer
         of Buyer, stating in reasonable detail the factual and legal basis for
         and the amount of one or more then unresolved claims against the
         Escrow Fund and such unresolved claims are for an amount equal to or
         in excess of the balance of the Escrow Fund, the Escrow Agent shall
         continue to hold the Escrow Fund until resolution of any such
         unresolved claim by a Certificate of Claim Resolution or a Final
         Order.  Upon receipt of such Certificate of Claim Resolution or Final
         Order, the Escrow Agent shall (x) pay to Buyer the amount set forth in
         such Certificate of Claim Resolution or such  Final Order in
         accordance with the provisions of Section 4(b), (y) retain as much of
         the Escrow Fund as is necessary to cover the full amount of any then
         still unresolved  claims, and (z) pay to Sellers the balance, if any,
         of the Escrow Fund in accordance with the provisions of Section
         4(c)(i).  Upon the payment of the





                                      -4-
<PAGE>   106
         entire Escrow Fund in accordance with the provisions of this Section
         4(c)(ii), this Agreement shall terminate.

                          (iii)   If there is then unresolved one or more
         Notices of a Pending Claim, and such unresolved claims are for an
         amount less than the balance of the Escrow Fund, the Escrow Agent
         shall pay to Sellers the excess of the balance of the Escrow Fund over
         the full amount of any then unresolved claims in accordance with the
         provisions of Section 4(c)(i).  The remaining balance of the Escrow
         Fund shall be retained and disposed of in accordance with the
         provisions of Section 4(c)(ii).

                 (d)      For all purposes of this Section 4, the value of each
Buyer's Share constituting a portion of the Stock Portion of the Escrow Fund
shall be deemed to be the Common Stock Market Price.

                 5.       Terms and Conditions to Escrow Agent's Acceptance.
Acceptance by the Escrow Agent of its duties under this Agreement is subject to
the following terms and conditions, which the parties to this Agreement hereby
agree shall govern and control the rights, duties and immunities of the Escrow
Agent:

                          (a)     The duties and obligations of the Escrow
Agent shall be determined solely by the express provisions of this Agreement
and the Escrow Agent shall not be bound by the provisions of the Stock Purchase
Agreement or any other agreement between or among 3-D, Buyer, Company, Sellers
or any other Person;

                          (b)     The Escrow Agent shall not be responsible for

any of the provisions of this Agreement;

                          (c)     The fees of the Escrow Agent in administering
this Agreement shall be borne by 3-D and Buyer.  3-D, Buyer and Sellers will
jointly indemnify the Escrow Agent for, and hold it harmless against, any loss,
liability or expense, including reasonable attorneys' fees and expenses,
incurred without bad faith, willful misconduct or gross negligence on the part
of the Escrow Agent arising out of or in connection with its acceptance of, or
the performance of its duties and obligations under, this Agreement.  The
provisions of this Section 5(c) shall survive any termination of this
Agreement;

                          (d)     The Escrow Agent shall be fully protected in
acting on and relying upon any written notice, direction, re-quest, waiver,

<PAGE>   107
                          (e)     The Escrow Agent shall not be liable for any
error of judgment, or for any act done or step taken or omitted by it in good
faith or for any mistake in fact or law, or for anything which it may do or
refrain from doing in connection herewith, except as a result of its own bad
faith, willful misconduct or gross negligence;

                          (f)     The Escrow Agent may seek the advice of legal
counsel in the event of any dispute or question as to the construction of any
of the provisions of this Agreement or its duties hereunder, and it shall incur
no liability and shall be fully protected in respect of any action taken,
omitted or suffered by it in good faith in accordance with the written opinion
of such counsel; and

                          (g)     In the event of ambiguity in the provisions
governing the Escrow Fund or uncertainly on the part of the Escrow Agent as to
how to proceed, such that the Escrow Agent, in its sole and absolute judgment,
deems it necessary for its protection so to do, the Escrow Agent may refrain
from taking any action other than to retain custody of the Escrow Fund until it
shall have received written instructions signed by Buyer and the Sellers'
Representative, or may deposit the Escrow Fund with a court of competent
jurisdiction and thereupon have no further duties or responsibilities in
connection therewith.

                 6.       Resignation or Removal of Escrow Agent.

Escrow Fund to the Successor Escrow Agent, net of any fees and expenses or
other obligations then owed to the Escrow Agent.  After appointment of the
Successor Escrow Agent and delivery of the Escrow Fund by the Escrow Agent, the
Escrow Agent shall have no further duties or responsibilities in connection
herewith.

                          (b)     Buyer and the Sellers' Representative may
remove the Escrow Agent upon written notice to the Escrow Agent signed by the
Buyer and the Sellers' Representative stating such removal and designating a
Successor Escrow Agent, and, upon delivery of the Escrow Fund to the Successor
Escrow Agent, net of any fees or expenses then owed to the Escrow Agent, the
Escrow Agent shall thereupon be discharged from all obligations under this
Agreement and shall have no further duties or responsibilities in connection
herewith.

                          (c)     If after thirty (30) days from the date of
delivery of its written notice of intent to resign, or of Buyer's and the

                  EXCHANGE RIGHT AND AUTOMATIC EXCHANGE RIGHTS

2.1               GRANT AND OWNERSHIP OF THE EXCHANGE RIGHT. In consideration 
of the granting of the Call Rights to 3-D, 3-D hereby grants to the Holders (a)
the right (the "Exchange Right"), upon the occurrence and during the continuance
of an Insolvency Event or a Default Event, to require 3-D to purchase from each
Holder all or any part of the Exchangeable Shares held by such Holder, and (b)
the Automatic Exchange Rights, all in accordance with the provisions of this
Agreement. 3-D hereby acknowledges receipt from the Holders of good and valuable
consideration (and the adequacy thereof) for the grant of the Exchange Right and
the Automatic Exchange Rights by 3-D to the Holders.

2.2               LEGENDED SHARE CERTIFICATES.  The Corporation shall cause each
certificate representing Exchangeable Shares to bear an appropriate legend
notifying the Holders of:


                                        5
<PAGE>   119
         (a)      the right to exercise the Exchange Right in respect of the 
                  Exchangeable Shares held by a Holder; and

         (b)      the Automatic Exchange Rights.

2.3               PURCHASE PRICE. The purchase price payable by 3-D for each 
Exchangeable Share to be purchased by 3-D under the Exchange Right shall be an
amount per share equal to (a) the Current Market Price multiplied by the Current
3-D Common Share Equivalent, in each case determined on the day of closing of
the purchase and sale of such Exchangeable Share under the Exchange Right, which
shall be satisfied in full in respect of the Exchangeable Shares in regard to
which a Holder has exercised the Exchange Right by causing to be delivered to
such Holder such whole number of 3-D Common Shares as is equal to the product
obtained by multiplying the number of such Exchangeable Shares by the Current
3-D Common Share Equivalent (together with an amount in lieu of any fractional
3-D Common Share resulting from such calculation payable in accordance with
section 10.4 of the Exchangeable Share Provisions), plus (b) the aggregate of
all dividends declared and unpaid on each such Exchangeable Share (provided that
if the record date for any such declared and unpaid dividends occurs on or after
the day of closing of such purchase and sale the purchase price shall not
include such declared and unpaid dividends).

2.4               EXERCISE OF THE EXCHANGE RIGHT. Subject to the terms and 
conditions herein set forth, a Holder shall be entitled, upon the occurrence and
during the continuance of an Insolvency Event or a Default Event, to exercise
the Exchange Right with respect to all or any part of the Exchangeable Shares
registered in the name of such Holder on the books of the Corporation. To
exercise the Exchange Right, the Holder shall deliver to 3-D, in person, by
courier or by certified or registered mail, at its principal office or at such
other place as 3-D may from time to time designate by written notice to the
Holders, the certificates representing the Exchangeable Shares that such Holder
desires 3-D to purchase pursuant to the Exchange Right, duly endorsed in blank,
and accompanied by such other documents and instruments as 3-D may reasonably
require together with:

         (a)      a duly completed form of notice of exercise of the Exchange 
                  Right, contained on the reverse of or attached to the
                  Exchangeable Share certificates, stating (i) that the Holder
                  thereby exercises the Exchange Right so as to require 3-D to
                  purchase from the Holder the number of Exchangeable Shares
                  specified therein, (ii) that such Holder has good title to and
                  owns all such Exchangeable Shares to be acquired by 3-D free
                  and clear of all Liens, (iii) the names in which the
                  certificates representing 3-D Common Shares issuable in
                  connection with the exercise of the Exchange Right are to be
                  issued, and (iv) the names and addresses of the Persons to
                  whom such new certificates should be delivered;

         (b)      payment (or evidence satisfactory to 3-D of payment) of the 
                  taxes (if any) payable as contemplated by section 2.7 hereof;
                  and

         (c)      a certificate or certificates of such Holder satisfactory to
                  3-D attesting to such Holder's accredited investor status and
                  investment intent.


                                        6
<PAGE>   120
If only a part of the Exchangeable Shares represented by any certificate or
certificates delivered to 3-D are to be purchased by 3-D under the Exchange
Right, a new certificate for the balance of such Exchangeable Shares shall be
issued to the Holder at the expense of the Corporation.

2.5               DELIVERY OF 3-D COMMON SHARES: EFFECT OF EXERCISE. Promptly 
after receipt of the certificates, duly endorsed in blank, representing the
Exchangeable Shares in respect of which the Exchange Right was exercised
pursuant to section 2.4 hereof (together with such documents and instruments of
transfer and a duly completed form of notice of exercise of the Exchange Right
(and payment of taxes, if any, or evidence thereof in accordance with section
2.4 hereof, 3-D shall notify the Corporation of its receipt of the same and 3-D
shall immediately thereafter deliver or cause to be delivered to the Holder of
such Exchangeable Shares (or to such other Persons, if any, properly designated
by such Holder), the certificates for the number of 3-D Common Shares issuable
in connection with the exercise of the Exchange Right, which shares shall be
duly issued as fully paid and non-assessable and shall be free and clear of any
Liens placed thereon by 3-D or the Corporation, and cheques for the balance, if
any, of the total purchase price therefor (or, if part of the purchase price
consists of dividends payable in property, such property or property the same as
or economically equivalent to such property). Immediately upon the exercise of
the Exchange Right, as provided in section 2.4 hereof, the closing of the
transaction of purchase and sale contemplated by the Exchange Right shall be
deemed to have occurred, and the Holder of such Exchangeable Shares shall be
deemed to have transferred to 3-D all of its right, title and interest in and to
such Exchangeable Shares free and clear of all Liens and shall cease to be a
holder of such Exchangeable Shares and shall not be entitled to exercise any of
the rights of a holder in respect thereof, other than the right to receive the
purchase price therefor, unless the requisite number of 3-D Common Shares
(together with a cheque for the balance, if any, of the purchase price therefor
or, if part of the purchase price consists of dividends payable in property,
such property or property the same as or economically equivalent to such
property) is not allotted, issued and delivered by 3-D to such Holder (or to
such other Persons, if any, properly designated by such Holder) within five
Business Days of the date of the exercise of the Exchange Right, in which case
the rights of the Holder shall remain unaffected until such 3-D Common Shares
are so allotted, issued and delivered by 3-D and any such cheque or property is
so delivered and paid. Concurrently with such Holder ceasing to be a holder of
Exchangeable Shares, the Holder shall be considered and deemed for all purposes
to be the holder of the 3-D Common Shares delivered to it pursuant to the
Exchange Right. The Board of Directors shall sanction or approve any transfer of
Exchangeable Shares made pursuant to an exercise of the Exchange Right pursuant
to the provisions hereof and such sanction or approval shall be effective as at
the closing of the transaction of purchase and sale of Exchangeable Shares as
provided in this section 2.5.

2.6               EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION. In the 
event that a Holder has exercised its right under Article 5 of the Exchangeable
Share Provisions to require the Corporation to redeem any or all of the
Exchangeable Shares held by the Holder (the "Retracted Shares") and is notified
by the Corporation pursuant to section 5.6 of the Exchangeable Share Provisions
that the Corporation is not permitted as a result of solvency requirements of
applicable law to redeem all of such Retracted Shares, and provided that 3-D
shall not have exercised the Retraction Call Right with respect to the Retracted
Shares, the retraction request shall constitute and shall be deemed to
constitute an exercise of the Exchange


                                        7
<PAGE>   121
Right with respect to those Retracted Shares that the Corporation is unable to
redeem. In any such event, the Corporation hereby agrees with the Holder
immediately to notify 3-D of such prohibition against the Corporation redeeming
all of the Retracted Shares and immediately to forward or cause to be forwarded
to 3-D all relevant materials delivered by the Holder to the Corporation
(including without limitation a copy of the retraction request delivered
pursuant to section 5.1 of the Exchangeable Share Provisions) in connection with
such proposed redemption of the Retracted Shares and 3-D shall thereupon
purchase the Retracted Shares that the Corporation is not permitted to redeem in
accordance with the provisions of this Article 2.

2.7            STAMP OR OTHER TRANSFER TAXES. Upon any sale of Exchangeable 
Shares to 3-D pursuant to the Exchange Right or the Automatic Exchange Rights,
the share certificate or certificates representing 3-D Common Shares to be
delivered in connection with the payment of the purchase price therefor shall be
issued in the name of the Holder of the Exchangeable Shares so sold or in such
names as such Holder may otherwise direct in writing without charge to the
Holder, provided, however, that such Holder (a) shall pay (and neither 3-D nor
the Corporation shall be required to pay) any documentary, stamp, transfer or
other similar taxes that may be payable in respect of any transfer involved in
the issuance or delivery of such shares to a Person other than such Holder or
(b) shall establish to the satisfaction of 3-D and the Corporation that such
taxes, if any, have been paid.

2.8            NOTICE OF INSOLVENCY EVENT OR DEFAULT EVENT. Immediately upon the
occurrence of an Insolvency Event or a Default Event or any event that with the
giving of notice or the passage of time or both would be an Insolvency Event or
a Default Event, the Corporation and 3-D shall give written notice thereof to
the Holders. Such notice shall describe the event that has occurred and shall
specify that, pursuant to this Agreement, the Holders are currently entitled, or
may become entitled at a later date, to exercise the Exchange Right.

2.9            QUALIFICATION OF 3-D COMMON SHARES. 3-D shall use all reasonable
efforts to obtain all orders required from the applicable Canadian securities
authorities to permit the issuance of the 3-D Common Shares upon any exchange of
the Exchangeable Shares for 3-D Common Shares without registration or
qualification with, or approval of, or the filing of any document including any
prospectus or similar document, or the taking of any proceeding with, or the
obtaining of any order, ruling or consent from, any governmental or regulatory
authority under any Canadian federal or provincial law or regulation or pursuant
to the rules and regulations of any regulatory authority in Canada or the
fulfillment of any other legal requirement before such 3-D Common Shares may be
issued and delivered by the Corporation or 3-D to the holder thereof.

warrants that it has irrevocably reserved for issuance out of its authorized and
unissued capital stock such number of 3-D Common Shares as is equal to the
number of Exchangeable Shares outstanding at the date hereof and covenants that
it will at all times keep available, free from pre-emptive and other rights, out
of its authorized and unissued capital stock such number of 3-D Common Shares
(or other shares or securities into which 3-D Common Shares may be reclassified
or changed) as is necessary to enable 3-D and the Corporation to perform their

         (b) On the fifth Business Day prior to the effective date of an
Automatic Exchange, Event (the "Automatic Exchange Event Effective Date") all of
the then outstanding Exchangeable Shares shall be automatically exchanged for
3-D Common Shares. To effect such automatic exchange, 3-D shall purchase each
Exchangeable Share outstanding on the fifth Business Day prior to the Automatic
Exchange Event Effective Date and held by Holders, and each Holder shall sell
the Exchangeable Shares held by it at such time, for a purchase price per share
equal to (a) the Current Market Price multiplied by the Current 3-D Common Share
Equivalent on such fifth Business Day prior to the Automatic Exchange Event
Effective Date, which shall be satisfied in full in respect of the Exchangeable
Shares held by each Holder by 3-D issuing to such Holder such whole number of
3-D Common Shares as is equal to the product obtained by multiplying the number
of such Exchangeable Shares by the Current 3-D Common Share Equivalent (together
with an amount in lieu of any fractional 3-D Common Share resulting from such
calculation payable in accordance with section 10.4 of the Exchangeable Share
Provisions), plus (b) an additional amount equal to the aggregate of all
dividends declared and unpaid on each such Exchangeable Share (provided that if
the record date for any such declared and unpaid dividends occurs on or after
the day of closing of such purchase and sale, the purchase price shall not
include such additional amount equal to such declared and unpaid dividends). The
Board of Directors shall sanction or approve any transfer of Exchangeable Shares
made pursuant to the Automatic Exchange Rights and such sanction or approval
shall be effective as of the fifth Business Day prior to the Automatic Exchange
Event Effective Date.

         (c) On the fifth Business Day prior to the Automatic Exchange Event
Effective Date, the closing of the transaction of purchase and sale contemplated
by the automatic exchange of Exchangeable Shares for 3-D Common Shares shall be
deemed to have occurred, and each Holder of Exchangeable Shares shall be deemed
to have transferred to 3-D all of the Holder's right, title and interest in and
to such Exchangeable Shares free and clear of all Liens and shall cease to be a
holder of Exchangeable Shares and 3-D shall issue to the Holder the 3-D Common
Shares issuable upon the automatic exchange of Exchangeable Shares for 3-D
Common Shares

and shall deliver to the Holder a cheque for the balance, if any, of the
purchase price for such Exchangeable Shares (or, if any part of the purchase
price consists of dividends payable in property, such property or property that
is the same as or economically equivalent to such property). Concurrently with
such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be
considered and deemed for all purposes to be the holder of the 3-D Common Shares
issued to it pursuant to the automatic exchange of Exchangeable Shares for 3-D
Common Shares and the certificates held by the Holder previously representing
the Exchangeable Shares exchanged by the Holder with 3-D pursuant to such
automatic exchange shall thereafter be deemed to represent the 3-D Common Shares
issued to the Holder by 3-D pursuant to such automatic exchange. Upon the
request of a Holder and the surrender by the Holder of Exchangeable Share
certificates deemed to represent 3-D Common Shares, duly endorsed in blank and
accompanied by such instruments of transfer as 3-D may reasonably require, 3-D
shall deliver or cause to be delivered to the Holder certificates representing
the 3-D Common Shares of which the Holder is the holder.

holder of Exchangeable Shares, 3-D shall forthwith issue and deliver the
requisite 3-D Common Shares to or to the order of the former holder of the
surrendered Exchangeable Shares, as the Corporation shall direct. All such 3-D
Common Shares shall be duly issued as fully paid and non-assessable and shall be

Common Share by 3-D, the Corporation shall issue to 3-D, or as 3-D shall direct,
such number of common shares of the Corporation as is equal to the fair value of
such 3-D Common Shares.

2.6               QUALIFICATION OF COMMON SHARES. 3-D shall use all reasonable
efforts to obtain all orders required from the applicable Canadian securities
authorities to permit the issuance of the 3-D Common Shares upon any exchange of

<PAGE>   136

and on an economically equivalent basis as the holders of 3-D Common Shares,
without discrimination. Without limiting the generality of the foregoing, 3-D
will use all commercially reasonable efforts expeditiously and in good faith to
ensure that holders of Exchangeable Shares may participate in all such Offers

attending each meeting of holders of Exchangeable Shares in order to be counted
as part of the quorum for each such meeting. 3-D further covenants and agrees
that it will not, and will cause its Affiliates not to, exercise any voting
rights that may be exercisable by holders of Exchangeable Shares from time to
time pursuant to the Exchangeable Share Provisions or pursuant to the provisions
of the CBCA with respect to any Exchangeable Shares held by it or by its
Affiliates in respect of any matter considered at any meeting of holders of
Exchangeable Shares, including without limitation any approval to be given by
holders of Exchangeable Shares pursuant to section 9.2 of the Exchangeable Share
Provision.

such event being called a "Capital Reorganization"), 3-D shall take all such
actions and do all such things as are necessary to ensure that holders of
Exchangeable Shares

<PAGE>   137

whose Exchangeable Shares have not been exchanged or automatically exchanged for
3-D Common Shares in accordance with the Exchangeable Share Provisions or the
Share Exchange Agreement on or before the record date for such Capital
Reorganization shall receive, upon any such exchange occurring pursuant to the
Exchangeable Share Provisions or the Share Exchange Agreement at any time after
the record date for such Capital Reorganization, in lieu of the 3-D Common
Shares that such holders would otherwise have been entitled to receive pursuant
to the Exchangeable Share Provisions or the Share Exchange Agreement, the number
of shares or other securities of 3-D or of the body corporate resulting,
surviving or continuing from the Capital Reorganization, or other property, that
such holders would have been entitled to receive as a result of such Capital
Reorganization if, on the record date, such holders would have been the
registered holders of the number of 3-D Common Shares to which such holders were
then entitled upon any exchange of their Exchangeable Shares into 3-D Common
Shares in accordance with the Exchangeable Share Provisions or the Share
Exchange Agreement, subject to adjustment thereafter in the same manner, as
nearly as may be possible, as is provided for in subsection 1.1(o) of the
Exchangeable Share Provisions; provided that, in the event that all the
outstanding Exchangeable Shares are not exchanged or automatically exchanged for
3-D Common Shares in accordance with the provisions hereof or the Share Exchange
Agreement on or before the record date for such Capital Reorganization, such
Capital Reorganization shall not be carried into effect unless all necessary
steps shall have been taken so that each holder of Exchangeable Shares shall
thereafter be entitled to receive, upon any exchange of his Exchangeable Shares
pursuant to the Exchangeable Share Provisions or the Share Exchange Agreement,
such number of shares or other securities of 3-D or of the body corporate
resulting, surviving or continuing from the Capital Reorganization, or other
property.

reclassification of, or other change in the outstanding 3-D Common Shares other
than (i) a 3-D Common Share Reorganization, (ii) a Capital Reorganization, or
(iii) an Automatic Exchange Event (as defined in the Share Exchange Agreement,
3-D shall take all such actions and do all such things as are necessary to
ensure that holders of Exchangeable Shares shall receive, upon the occurrence at
any time after such record date of any event whereby they would receive 3-D
Common Shares pursuant to the Exchangeable Share Provisions or the Share
Exchange Agreement, such shares, securities or rights as they would have
received if their Exchangeable Shares had been exchanged for 3-D Common Shares
pursuant to the Exchangeable Share Provisions or the Share Exchange Agreement
immediately prior to such record date, subject to adjustment thereafter in the
same manner, as nearly as may be possible, as is provided for in subsection
1.1(o) of the Exchangeable Share Provisions.

                                   ARTICLE XI

                                 Indemnification

                  11.1 Survival of Representations, Warranties and Covenants.
The representations, warranties and covenants of the parties contained in this
Agreement, any Schedule or any certificate delivered pursuant hereto shall
survive the Closing. Each party hereto shall be entitled to rely on any such
representation or warranty regardless of any inquiry or investigation made by on
behalf of such party.

                  11.2 Indemnification by Sellers. Sellers shall jointly and
severally indemnify and hold harmless 3-D, Buyer, Company, J.R.S. and their
respective directors, officers and employees from and against any Loss incurred
or suffered by such Person as a result of, arising from or in connection with:

                  (i) a breach by a Seller of any representation or warranty
         made by such Seller in this Agreement or in any Schedule or certificate
         delivered pursuant hereto;

                  (ii) a failure by a Seller to perform or comply with any
         covenant or agreement on the part of such Seller contained herein,
         including any covenant contained in Article VI; and

                  (iii) any claim by or on behalf of Jill Ann Siegfried or Kari
         Lee Siegfried with respect to or arising out of the ownership,
         transfer, exchange of or subscription for shares of Class B Non-Voting
         Common Stock of the Company.

The amount paid pursuant to the preceding sentence shall be paid to Buyer or, at
Buyer's election, to Company and shall be the amount required to put Buyer,
Company or J.R.S., as the case may be, in the after tax position it would have
been in had such representation, warranty, covenant or agreement not been
breached. Any payment made by a Seller to Buyer under this Section 11.2 shall be
treated as a reduction in the aggregate consideration received by such Seller
from Buyer pursuant to this Agreement. Any such payment made by a Seller to
Company shall be treated as a capital contribution to Company.

                  11.3 Indemnification by 3-D and Buyer. 3-D and Buyer shall
jointly and severally indemnify and hold harmless each Seller from and against
any Loss incurred or suffered by such Seller as a result of, arising from or in
connection with:

                  (i) a breach by 3-D or Buyer of any representation or warranty
         made by 3- D or Buyer in this Agreement or in any Schedule or
         certificate delivered pursuant hereto or in the Support Agreement or
         the Share Exchange Agreement; and

                  (ii) a failure by 3-D or Buyer to perform or comply with any
         covenant or agreement on the part of 3-D or Buyer contained herein,
         including any covenant


                                       32
<PAGE>   38
         contained in Article VII, or in the Support Agreement or the Share 
         Exchange Agreement.

                  11.4 Assumption of Defense. An indemnified party shall
promptly give notice to each indemnifying party after obtaining knowledge of any
matter as to which recovery may be sought against such indemnifying party
because of the indemnity set forth above, and, if such indemnity shall arise
from the claim of a third party, shall permit such indemnifying party to assume
the defense of any such claim or any litigation resulting from such claim;
provided, however, that failure promptly to give any such notice shall not
affect the indemnification provided under this Article XI except to the extent
such indemnifying party shall have been prejudiced as a result of such failure.
Notwithstanding the foregoing, an indemnifying party may not assume the defense
of any such third-party claim if it does not demonstrate to the reasonable
satisfaction of the indemnified party that it has adequate financial resources
to defend such claim and pay any and all Losses that may result therefrom, or if
the claim (i) is reasonably likely to result in imprisonment of the indemnified
party, (ii) is reasonably likely to result in a criminal penalty or fine against
the indemnified party the consequences of which would be reasonably likely to
have a material adverse effect on the indemnified party unrelated to the size of
such penalty or fine, or (iii) is reasonably likely to result in an equitable
remedy which would materially impair the indemnified party's ability to exercise
its rights under this Agreement, or impair 3-D's or Buyer's right or ability to
operate Company. If an indemnifying party assumes the defense of such third
party claim, such indemnifying party shall agree prior thereto in writing that
it is liable under this Article XI to indemnify the indemnified party in
accordance with the terms contained herein in respect of such claim, shall
conduct such defense diligently, shall have full and complete control over the
conduct of such proceeding on behalf of the indemnified party and shall, in his
or her or its sole discretion, have the right to decide all matters of
procedure, strategy, substance and settlement relating to such proceeding;
provided, however, that any counsel chosen by such indemnifying party to conduct
such defense shall be reasonably satisfactory to the indemnified party. The
indemnified party may participate in such proceeding and retain separate co-
counsel at its sole cost and expense, and the indemnifying party will not
without the written consent of the indemnified party consent to the entry of any
judgment or enter into any settlement with respect to the matter which does not
include a provision whereby the plaintiff or the claimant in the matter releases
the indemnified party from all liability with respect thereto. Failure by an
indemnifying party to notify the indemnified party of its election to defend any
such claim or action by a third party within thirty (30) days after notice
thereof shall have been given to such indemnifying party by the indemnified
party shall be deemed a waiver by such indemnifying party of its right to defend
such claim or action.

                  11.5 Non-Assumption of Defense. If no indemnifying party is
permitted or elects to assume the defense of any such claim by a third party or
litigation resulting therefrom, the indemnified party shall diligently defend
against such claim or litigation in such manner as it may deem appropriate and,
in such event, the indemnifying party or parties shall promptly reimburse the
indemnified party for all reasonable out-of-pocket costs and expenses, legal or
otherwise, incurred by the indemnified party and its affiliates in connection
with the defense against such claim or litigation, as such costs and expenses
are


                                       33
<PAGE>   39
incurred. Any counsel chosen by such indemnified party to conduct such defense
must be reasonably satisfactory to the indemnifying party or parties, and only
one counsel shall be retained to represent all indemnified parties in an action
(except that if litigation is pending in more than one jurisdiction with respect
to an action, one such counsel may be retained in each jurisdiction in which
such litigation is pending).

                  11.6 Indemnified Party's Cooperation as to Proceedings. The
indemnified party will cooperate in all reasonable respects with any
indemnifying party in the conduct of any proceeding as to which such
indemnifying party assumes the defense. For the cooperation of the indemnified
party pursuant to this Section 11.6, the indemnifying party or parties shall
promptly reimburse the indemnified party for all reasonable out-of-pocket costs
and expenses, legal or otherwise, incurred by the indemnified party or its
affiliates in connection therewith, as such costs and expenses are incurred.

                  11.7 General Limitations on Indemnification.

                  (a) An indemnifying party shall not be liable to nor required
to indemnify or hold an indemnified party harmless with respect to any Loss to
the extent such Loss is recoverable under insurance policies maintained by the
indemnified party or its affiliates.

                  (b) If any Loss indemnified against under this Article XI
shall result (after giving effect to any differences in the timing of
recognition, payment and deductibility) in a direct or indirect Tax savings to
the indemnified party or its affiliates, then the Indemnification Obligations to
which such indemnified party shall be entitled hereunder shall be reduced by the
amount of such Tax savings.


                                   ARTICLE XII

                                  Miscellaneous

by an instrument in writing, duly executed by all of the parties hereto.

                  12.5 Nonwaiver. No waiver by any party of any term, provision,
covenant, representation or warranty contained in this Agreement (or any breach
thereof) shall be effective unless it is in writing executed by the party
against which such waiver is to be enforced; no waiver shall be deemed or
construed as a further or continuing waiver of any such term, provision,
covenant, representation or warranty (or breach) on any other occasion or as a
waiver of any other term, provision, covenant, representation or warranty (or of
the breach of any other term, provision, covenant, representation or warranty)
contained in this Agreement on the same or any other occasion.

                  12.6 Counterparts. For the convenience of the parties, any

one and the same instrument.

                  12.7 Assignment; Binding Nature; No Beneficiaries. This
Agreement may not be assigned by any party hereto without the written consent of
the other parties; provided, however, that Buyer may assign its rights hereunder

the preceding sentence, this Agreement shall be binding upon, inure to the
benefit of, and be enforceable by the parties hereto and their respective heirs,
personal representatives, legatees, successors and permitted assigns. Except as
otherwise expressly provided in Article XI, this Agreement shall not confer any

respective heirs, personal representatives, legatees, successors and permitted
assigns.

         EMPLOYMENT AGREEMENT (this "Agreement") dated as of [January __, 1997
]between J.R.S. Exploration Company Limited, an Alberta corporation (the

         WHEREAS, the Company desires to employ the Employee on the
terms and conditions provided in this Agreement; and


         WHEREAS, the Employee desires to accept such employment and to render
services to the Company on the terms and conditions provided in this Agreement;


         NOW, THEREFORE, in consideration of the mutual agreements herein

         Section 2. Term. Unless sooner terminated as provided in this

         Section 3.  Duties and Services.


         3.1 The Employee shall render services to the Company as its Sales
Manager and Operations Supervisor and shall perform such other duties and
responsibilities as may be assigned to the Employee from time to time by the
President of the Company or the Board of Directors of the Company (the
"Directors") and shall abide by the practices and policies of the Company
governing the conduct of employees. However, any assignments presented to the
Employee for continuous work outside of Canada for a duration of two weeks or
longer may be accepted or rejected in the discretion of the Employee.

         3.2 During the Term, the Employee shall devote such energy and time

         4.2 Bonus Pool. 3-D intends to create a bonus plan based upon the

subsidiaries, including the Company. The Employee shall be entitled to
participate in such plan on such terms as may be determined by the Compensation
Committee of the Board of Directors of 3-D, in its discretion. Nothing in this
Agreement shall require 3-D to pay any such bonus.

         Section 5. Expenses and Reimbursement. The Employee shall be reimbursed
by the Company for reasonable and necessary out-of-pocket expenses incurred by
the Employee in performing his duties hereunder, provided such expenses are

Employee, on the Effective Date the Employee shall be granted an option (the

as follows:

                                      -5-
<PAGE>   50
         8.1 Covenant Not to Compete. The Employee will not in any way, directly
or indirectly, as an agent, employee, officer, director, stockholder, partner or
otherwise of any corporation, partnership or other venture or enterprise compete
with the Company, 3-D or any of their respective subsidiaries in the provision
of seismic data acquisition or analysis services or any services related thereto
(a "Competing Business"), during the Term.

         8.2 Non-Solicitation Covenant. During the Term and for a period of one
(1) year after the termination of this Agreement for any reason whatsoever, the
Employee shall not solicit, sell to or contract with, on behalf of the Employee
or on behalf of any Competing Business, any person or entity to which the
Company or any subsidiary of the Company shall have provided seismic data
acquisition or analysis services at any time during the Term.


         8.3 Covenant Not to Solicit Employees of the Company. During the Term
and for a period of one (1) year after the termination of this Agreement for any
reason whatsoever, the Employee shall not solicit for employment any sales,
engineering or other technical or management employee who was employed by the
Company or any of its subsidiaries during the Term.

         8.4 Non-Disclosure Covenant. The Employee recognizes and acknowledges
that, in the course of his employment, the Employee will have access to trade
secrets and other confidential or proprietary information of the Company, 3-D
and their respective 


                                      -6-
<PAGE>   51
subsidiaries, including, but not limited to, information concerning seismic
data, marketing strategy, technology, techniques and know-how, customer
specifications and customer lists, cost figures, budgets, sales forecasts and
business plans. The Employee agrees that the disclosure of any such trade
secrets or information could be harmful to the interests of the Company, 3-D or
such subsidiaries and that, during the Employee's employment by the Company or
its subsidiaries, the Employee will take appropriate caution to safeguard such
trade secrets and information, and will not during the Term or thereafter use,
disclose, divulge or publish any such trade secrets or information except as
required by law or as the Employee's duties during the Employee's employment by
the Company or its subsidiaries may require or as the Company may in writing
specifically consent.


         8.5 Proprietary Information. The Employee recognizes and acknowledges
that all documents, manuals, letters, notebooks, reports, records, computer
programs or data banks and other evidences of trade secrets and other
confidential or proprietary information of the Company, 3-D and their respective
subsidiaries, including copies thereof, whether prepared by the Employee or
others, are the sole property of and belong exclusively to the Company, 3-D and
their respective subsidiaries, and agrees that, during the Employee's employment
by the Company or its subsidiaries, the Employee will under no circumstances
remove any such material for use outside of his offices except in connection
with the business of the Company 

                                      -7-
<PAGE>   52
during the course of the Employee's employment. In the event of the termination
of this Agreement for any reason whatsoever, the Employee shall immediately
return to the Company any and all documents, manuals, letters, notebooks,
records, computer programs or data banks or other evidence of trade secrets and
other confidential or proprietary information of the Company, 3-D and their
respective subsidiaries, including copies thereof, which are the property of the
Company, 3-D or any of their respective subsidiaries.


         8.6 Remedies. The Employee further agrees that in the event of a breach
or threatened breach of any of the covenants contained in this Section 8, the
Company's remedy at law is likely to be inadequate and that accordingly the
Company will be entitled to obtain an injunction or other equitable relief with
regard thereto without proving damages or that damages would not constitute an
adequate remedy. If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 8 is invalid or
unenforceable, the parties hereto agree that the court making the determination
of invalidity or unenforceability shall have the power to, and is hereby
directed to, reduce the scope, duration or area of the term or provision, to
delete specific words or phrases, or to replace any invalid or unenforceable
term or provision with a term or provision that is valid and enforceable and
that comes closest to expressing the intention of the invalid and unenforceable
term or provision, and this Agreement shall be enforceable as so modified.

        Re:  3-D Geophysical, Inc.: Registration Statement on
             Form S-1 (Registration No. 333-13665)

Dear Sirs and Mesdames:

        We have acted as counsel to 3-D Geophysical, Inc., a Delaware
corporation (the "Company"), in connection with the preparation and filing of
the above-captioned Registration Statement on Form S-1 (the "Registration
Statement") under the Securities Act of 1933, as amended (the "Securities
Act"), covering 4,945,000 shares of common stock, par value $.01 per share, of
the Company (the "Shares"), including up to 645,000 shares of common stock to
be sold upon exercise of an over-allotment option granted by the Company to
Smith Barney Inc., Rauscher Pierce Refsnes, Inc. and Simmons & Company
International, as representatives of the several underwriters (the
"Representatives"). The Shares are to be sold pursuant to an underwriting
agreement to be entered into by and among the Company and the Representatives
(the "Underwriting Agreement").
<PAGE>   2
KRAMER, LEVIN, NAFTALIS & FRANKEL

December 11, 1996


        As such counsel, we have examined such corporate records, certificates
and other documents as we have considered necessary or appropriate for the
purposes of this opinion. In rendering this opinion, we have assumed (i) the
genuineness of all signatures on documents examined by us, (ii) the
authenticity of all documents submitted to us as originals, and (iii) the
conformity to original documents of all documents submitted to us as
photostatic or conformed copies and the authenticity of the originals of such
copies. We have also relied on certificates of public officials and, as to
matters of fact, statements and certificates of officers of the Company.

        Based upon the foregoing, we are of the opinion that the Shares, when
issued and sold in accordance with the terms of the Underwriting Agreement and
as described in the prospectus forming a part of the Registration Statement
(the "Prospectus"), will be validly issued, fully-paid and non-assessable
shares of common stock of the Company.

        We are attorneys admitted to the Bar of the State of New York, and we
express no opinion as to the laws of any other jurisdiction other than the laws
of the United States of America and the General Corporation Law of the State of
Delaware.

        Arthur D. Emil, Esq., a director of the Company, is of counsel to this
firm. Mr. Emil has been granted ten-year options to purchase an aggregate of
16,667 shares of Common Stock and owns 5,789 shares of Common Stock.

        We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving such consent we do not thereby concede
that we are within the category of persons whose consent is required under
Section 7 of the Securities Act or the rules and regulations promulgated
thereunder.

        We are delivering this opinion to the Company, and no person other than
the Company is entitled to rely upon it without our prior written consent.

                                        Very truly yours,

JD dated February, 1996, and all rights and obligations thereunder, is hereby
terminated as of October 1, 1996 (the "Effective Date").


         2.      Consideration.

                 2.1      On January 3, 1997, the Company shall pay to JD

participation, on the same basis as senior executives of the Company, in
accordance with and subject to the respective terms and conditions thereof as
to eligibility and otherwise, in the Company's medical, dental, long-term
disability and standard life insurance programs (subject to insurability at
standard rates, it being understood and agreed that if insurance becomes
unavailable at standard rates, the Company shall maintain the insurance
provided that the difference in premiums between standard and actual rates is
paid by JD).
<PAGE>   2
                 2.4      The Company shall make available to JD an office at
the Company's New York offices, and such secretarial assistance and general
office support as JD may reasonably require, until December 31, 1997, provided
that JD shall not, as an officer, engage or participate in any business
enterprise that is in whole or substantial part in competition with the Company
or any of its subsidiaries during such period.

                 2.5      JD will provide to the Company financial and 
advisory services in connection with the Offering and the proposed acquisition 
of J.R.S.


         3.      Confidential Information.

                 3.1      JD agrees that he will not disclose to any person,
corporation, firm, partnership or other entity whatsoever (except the Company
or any of its subsidiaries or affiliates), or use for his own benefit, any
confidential or proprietary information with respect to the Company's trade
secrets, financial condition, marketing programs or otherwise related to the
Company's business and affairs that JD learned of or had access to as a result
of his employment by the Company ("Confidential Information"), which
Confidential Information is not in the public domain through no fault of JD's.
Notwithstanding anything hereinabove to the contrary, the Company authorizes JD
to make disclosure of Confidential Information (x) pursuant to a court order by
a court of competent jurisdiction, or (y) to any authority exercising
executive, legislative, regulatory or administrative functions of or pertaining
to a government having jurisdiction with respect to the Company or JD.

                 3.2      The Company shall be entitled, in addition to any
other right and remedy it may have, at law or in equity, to an injunction,
without the posting of any bond or other security and without proving that
damages would not be an adequate remedy, enjoining or restraining JD from any
material violation or threatened material violation of Section 3.1 and JD
hereby consents to the issuance of such injunction.  If any of the restrictions
contained herein shall be deemed to be unenforceable by reason of the extent,
duration or scope thereof or otherwise, then the parties hereto contemplate
that the court shall reduce such extent, duration, scope or other provision
hereof and enforce this Section 3 in its reduced form for all purposes in the
manner contemplated hereby.  This Section 3.2 and Section 3.1 shall survive the
payment of the consideration to JD under this Agreement.

                 4.2      Entire Agreement; Amendment; Amendment of Prior
Agreements.  This Agreement contains the entire agreement between the parties,
merges all prior negotiations, agreements and understandings, if any, and
states in full all representations, warranties and agreements which have
induced this Agreement.  Each party agrees that in dealing with third parties
no contrary representations will be made.  This Agreement may not be amended,
modified or otherwise changed orally but only by an agreement in writing signed
by the party against which enforcement of any amendment, modification or change
is sought.  This Agreement amends and restates in its entirety that certain
Termination Agreement dated as of October 1, 1996 between the Company and JD. 
The consulting agreement between the Company and Megansett Capital, Inc.  
("Megansett") dated February 1996 pursuant to which the Company is obligated to
pay to Megansett $125,000 in February 1997 is hereby amended to provide that 
such payment shall be made on January 3, 1997.

                 4.3      Assignment; Binding Nature; Assumption.   This
Agreement shall inure to the benefit of and be enforceable by JD and his
personal representatives, heirs, successors and assigns and shall be binding
upon the Company, any purchaser of all or substantially all of the Company's
business or assets, any successor to the Company or any assignee thereof
(whether direct or indirect, by purchase, merger, consolidation or otherwise).
The Company will require any such purchaser, successor or assignee expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such purchase,
succession or assignment had taken place.  This Agreement may not be assigned
by the JD without the prior written consent of the Company, except that JD may
assign this Agreement to Megansett, provided that no such assignment shall
relieve JD of his obligations under this Agreement and notwithstanding any such
assignment, JD shall personally perform the services provided for in Section
2.5.

                 4.4      Nonwaiver.  No waiver by any party of any term,
provision or covenant contained in this Agreement (or any breach hereof) shall
be effective unless it is in writing executed by the party against which such
waiver is to be enforced; no waiver shall be deemed or construed as a further
or continuing waiver of any such term, provision or covenant (or breach) on any
other occasion or as a waiver of any other term, provision or covenant (or of
the breach of any other term, provision or covenant) contained in this
Agreement on the same or any other occasion.

                 4.5      Remedies.  The remedies provided for or permitted by
this Agreement shall be cumulative and the exercise by any party of any remedy
provided for herein or otherwise available shall not preclude the assertion or
exercise by such party of any other right or remedy provided for herein or
otherwise available.  In the event the Company breaches this Agreement, JD
shall be entitled to recover reasonable attorneys fees incurred in connection
with enforcing this Agreement.
