THE COMPANY
 
  The Company is an oilfield service company specializing in providing an
integrated range of onshore seismic drilling, helicopter support and survey
services to geophysical companies operating in logistically difficult and
environmentally sensitive terrain in the United States. The Company's primary
market is the marsh, swamp, shallow water and contiguous dry land areas along
the U.S. Gulf Coast (the "Transition Zone"), primarily in Louisiana and Texas.
The Company is the leading provider of seismic drilling services throughout the
Transition Zone. From the mid-1980s to the end of 1996, the majority of three
dimensional ("3-D") seismic data in the Transition Zone has been obtained in
Louisiana, where approximately 9,000 square miles have been analyzed. The
Company performed the seismic drilling services on approximately 6,300 of these
square miles. The Company owns and operates an extensive fleet of specialized
seismic drilling and transportation equipment for use in the Transition Zone,
much of which is fabricated by the Company. As a result, the Company believes
that it is the only company that currently can both provide an integrated range
of seismic drilling, helicopter support and survey services in all of the
varied terrains of the Transition Zone and simultaneously support operations
for multiple, large-scale seismic projects. The Company has also expanded its
seismic drilling operations into the Rocky Mountain region, where it engages in
seismic drilling in hard rock terrain.
 
  Seismic data generally consists of computer-generated 3-D images or two-
dimensional ("2-D") cross sections of subsurface geologic formations and is
used in the exploration for hydrocarbon reserves and as a tool for enhancing
production from existing reservoirs. Seismic data is acquired by recording
subsurface seismic waves produced by an energy source, usually dynamite, at
various points ("source points") at a project site. The reflected seismic waves
are collected by specialized sensors ("geophones") placed at receiving points
("receiving points") throughout the project site, and the resulting data is
recorded by field recording boxes and then digitized.
 
  Oil and gas companies generally contract with independent geophysical
companies to acquire seismic data. Geophysical companies initially determine
the layout of source and receiving points and secure all necessary permits and
landowner consents. Once the permits and consents are obtained, the source and
receiving points are surveyed and marked, and the source points are drilled and
loaded with dynamite. The geophysical company then positions the geophones at
the receiving points and proceeds with detonation of the dynamite and the
acquisition of the seismic data. During this process, helicopters are sometimes
used to shuttle geophones and field recording boxes between receiving points
("long-line helicopter support") in an efficient manner with minimal
environmental impact. Domestically, seismic drilling, surveying and helicopter
support services are typically contracted to third parties such as the Company,
as geophysical companies have found it more economical to outsource these
services and focus their efforts and capital on the acquisition and
interpretation of seismic data. The use of this data to identify locations to
drill both exploration and development wells has improved the economics of
finding and producing oil and gas reserves, which in turn has created increased
demand for 3-D seismic surveys and seismic support services.
 
 
                                       3

  Seismic Drilling Services. Historically, the Company's core business has been
the drilling and loading of source points for seismic projects in the
Transition Zone. The Company's extensive fleet of specialized seismic drilling
and transportation equipment includes all-terrain marsh vehicles ("marsh ATVs")
equipped with on-board drilling units, all-terrain swamp vehicles ("swamp
ATVs"), pull boats equipped with skid-mounted drilling units, airboat drilling
units, support airboats, pontoon boats equipped with on-board drilling units,
highland drilling units used on dry land and skid-mounted drilling units used
on leased jack-up rigs. The Company uses its pontoon boats and leased jack-up
rigs in inland bays and lakes and coastal waters at depths of up to
approximately 20 feet. The Company designs and fabricates much of the
specialized seismic drilling and transportation equipment that it uses in the
Transition Zone, which management believes is superior to that generally
available in the market. This wide variety of efficient and environmentally
appropriate equipment enables the Company to respond to all of the seismic
drilling needs of its customers throughout the Transition Zone.
 
  Through its acquisition of substantially all of the assets of Wyoming-based
O.T.H. Exploration Services, Inc. ("OTH"), which was completed as of September
1, 1997, the Company provides seismic rock drilling services to geophysical
companies operating in the Rocky Mountain region. Seismic rock drilling
involves the use of compressed air rotary/hammer drills that are transported
from point to point by hand, surface vehicle or helicopter ("heli-portable
drilling"). The Company has also signed a non-binding letter of intent to
acquire American Helicopter Drilling, Inc. ("American Helicopter"), which
currently has the dominant share of the heli-portable seismic drilling market
in the Rocky Mountain area and is also engaged in the fabrication, export and
servicing of heli-portable and other types of seismic drilling units.
 
  Helicopter Support Services. The Company provides helicopter support services
to geophysical companies in the Transition Zone and elsewhere through its
aviation division, which was created through the July 1997 acquisition of
substantially all the assets of American Aviation Incorporated ("American
Aviation"), a company founded by the Company's Chairman and Chief Executive
Officer, David Jeansonne, in late 1995. The Company currently operates 16
helicopters (10 of which are owned and six of which are leased by the Company)
and owns and operates four airplanes to support its operations and to provide
limited charter services. Management believes that the Company is the dominant
provider of helicopter support services to geophysical companies operating in
the Transition Zone.
 
  Survey Services. After a geophysical company has determined the placement of
source and receiving points and obtained all necessary permits and consents for
a seismic project, survey teams are sent into the field to mark each source and
receiving point. In March and August 1997, respectively, the Company acquired
two survey companies, Delta Surveys, Inc. and Leonard J. Chauvin, Jr.,
Incorporated, and currently has 16 survey crews devoted primarily to the
seismic survey market in the Transition Zone. The Company also provides, on a
limited basis, civil survey services in south Louisiana to the oil and gas
industry and other industries. The Company's survey crews have access to the
Company's extensive fleet of specialized transportation equipment, which gives
the Company a competitive advantage over most other survey companies which must
rent this equipment.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to:
 
  Participate in Transition Zone Growth. Seismic data acquisition has been
conducted in the Transition Zone since the 1930s. Within the last decade,
however, improvements in oil and gas drilling and production techniques and the
advent of 3-D imaging have resulted in significantly increased seismic activity
throughout the Transition Zone. In 1996, 3-D seismic data was acquired from
approximately 4,900 square miles of the Transition Zone in Louisiana compared
to 1,500 square miles in 1995 and 1,000 square miles in 1994. During the first
six months of 1997, 3-D seismic data was acquired from approximately 4,100
square miles of the Transition Zone in Louisiana.
 
                                       4
<PAGE>
 
Management anticipates that demand for seismic data will continue to grow in
the Transition Zone as a result of 3-D seismic acquisition projects on
unexplored prospects, time-lapsed 3-D analysis, which is generally used to
measure the migration of hydrocarbons in a producing reservoir to enhance
production efforts, and reshoots of previously-surveyed areas with more
advanced seismic technology. The Company intends to maintain its dominant share
of the seismic drilling market in the Transition Zone by fully participating in
this growth.
 
  Integrate and Expand Services. The Company intends to capitalize on its
existing customer relationships and its reputation as a reliable service
provider in the Transition Zone to expand its newly-acquired helicopter support
and survey businesses. Management believes that the Company is the only
operator in the Transition Zone that can provide seismic drilling, helicopter
support and survey services on an integrated basis. Management further believes
that the Company's unique ability to package these services to meet its
customers' needs, together with the economies of scale provided by the size and
integrated nature of its operations, will allow the Company to attract
additional projects in the Transition Zone and elsewhere.
 
  Expand Operations in the Rocky Mountain Region. As a result of its recent
acquisition of substantially all of the assets of OTH, the Company has expanded
from its base in the Transition Zone into the seismic rock drilling market in
the Rocky Mountain region. The Company has also entered into a non-binding
letter of intent to acquire American Helicopter and has separately contracted
for delivery of two heavy-lift helicopters by year end, which will allow the
Company to provide integrated heli-portable seismic drilling services.
Management expects the demand for seismic data in the Rocky Mountain region to
grow over the next five years and believes that many of its current Transition
Zone customers will participate in this growth.
 
  Expand Internationally. Management believes that the Company will be well
positioned to expand internationally based on the comprehensive services it
provides in the Transition Zone, its experience operating in difficult terrains
and its recently acquired heli-portable and seismic rock drilling expertise.
Many of the Company's customers who operate in the Transition Zone also have
extensive international operations, but currently perform their own seismic
drilling and related services internationally. The Company believes that these
customers would outsource these services as they have done domestically if
there were reliable and cost-effective third party service providers operating
internationally. Mexico, Venezuela, Indonesia, Tunisia, the Caspian Sea, South
China and West Africa each have transition zones similar to the U.S. Gulf Coast
region where seismic exploration is in various stages of development.
Management believes that the Company's strong industry reputation and
established relationships with its customers will facilitate the Company's
entrance into and development in international markets.
 
  Acquire Related Businesses. Management intends to evaluate opportunities as
they arise to acquire companies that have related or complementary products or
services to those currently provided by the Company. The Company seeks
acquisitions which would, among other things, capitalize on the Company's
dominant position in the Transition Zone seismic drilling market, expand its
Rocky Mountain presence or facilitate its anticipated international expansion.
Immediately after the Offering, management believes that the Company's capital
structure will enable it to pursue such opportunities. However, the Company
does not intend to enter the seismic data acquisition market at any time.

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
 
  The following table presents for the periods indicated certain summary
historical and pro forma financial data of OMNI Geophysical and its
predecessor, OMNI Geophysical Corporation ("OGC"). OMNI Geophysical acquired
substantially all of the assets and liabilities of OGC on July 19, 1996 (the
"OGC Acquisition"). The OGC Acquisition was accounted for as a purchase, with
the assets acquired and liabilities assumed recorded at their stepped-up fair
value. Financial data for the years ended December 31, 1994 and 1995, the 201-
day period ended July 19, 1996 and the six months ended June 30, 1996 reflect
the results of OGC. Financial data for the 165-day period ended December 31,
1996 and the six months ended June 30, 1997 reflect the results of OMNI
Geophysical. The following data should be read in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the historical and pro forma financial statements and related
notes thereto included elsewhere in this Prospectus.

- --------
(a) The unaudited pro forma as adjusted income statement data give effect to
    (i) the OGC Acquisition, (ii) the acquisition of substantially all of the
    assets of American Aviation, (iii) the additional interest expense
    associated with borrowings to finance the Preferred Unit Repurchase and the
    LLC Distribution and (iv) the Offering and the application of the net
    proceeds therefrom, each as if consummated at January 1, 1996.
(b) The step-up to fair value of the assets acquired in the OGC Acquisition
    resulted in increased depreciation reported by OMNI Geophysical, which is
    included in operating expenses. In order to finance the OGC Acquisition,
    OMNI Geophysical incurred additional indebtedness, which resulted in
    additional interest expense being reported.
(c) Each of OGC, OMNI Geophysical and American Aviation is or was an S
    corporation or a limited liability company exempt from income tax at the
    entity level, and thus the historical financial statements show no
    provision for income taxes. The Company, however, is a corporation that
    will pay income taxes at the corporate level. This pro forma adjustment
    reflects a provision for income taxes on the Company's net income at a
    combined federal and state tax rate of 40%. See "Change in Tax Status and
    Related Distributions."
(d) Gives effect to (i) the Share Exchange, (ii) the payment of dividends on
    the outstanding preferred units of OMNI Geophysical of approximately
    $180,000 for the 165-day period ended December 31, 1996 and approximately
    $172,000 for the six months ended June 30, 1997 and (iii) the exercise of
    options to purchase 118,018 shares of Common Stock granted to employees of
    the Company outside of the Company's Stock Incentive Plan, as if each had
    occurred at the beginning of the period. See "The Company."
(e) Gives effect to (i) the Share Exchange, (ii) the acquisition of
    substantially all of the assets of American Aviation, (iii) the Preferred
    Unit Repurchase, (iv) the exercise of options to purchase 118,018 shares of
    Common Stock granted to employees of the Company outside of the Company's
    Stock Incentive Plan and (v) the Offering and the application of the net
    proceeds therefrom, as if each had occurred at the beginning of the period.
    See "The Company."
(f) The Company calculates EBITDA (earnings before interest expense, income
    taxes, depreciation and amortization) as operating income plus depreciation
    and amortization. EBITDA should not be considered as an alternative to net
    income or any other measure of operating performance determined in
    accordance with generally accepted accounting principles. EBITDA is widely
    used by financial analysts as a measure of financial performance. The
    Company's measurement of EBITDA may not be comparable to similarly titled
    measures reported by other companies.
(g) The unaudited pro forma as adjusted balance sheet data gives effect to (i)
    the acquisition of substantially all of the assets of American Aviation,
    (ii) the Share Exchange, (iii) the Preferred Unit Repurchase, (iv) the LLC
    Distribution and (v) the Offering and the application of the net proceeds
    therefrom as described herein. See "Use of Proceeds."

                                 RISK FACTORS
 
  Prospective purchasers of the Common Stock should carefully consider the
investment considerations set forth below, as well as the other information
contained in this Prospectus. All statements, other than statements of
historical fact, included in this Prospectus that address activities, events
or developments that the Company expects, believes or anticipates will or may
occur in the future are based on certain assumptions and analyses made by the
Company in light of its experiences and its perception of historical trends,
current conditions, expected future developments and other factors it believes
are appropriate under the circumstances when such assumptions and analyses
were made. Such statements are subject to a number of assumptions, risks and
uncertainties, including the risk factors discussed below, general economic
and business conditions, the business opportunities (or lack thereof) that may
be presented to and pursued by the Company, changes in laws or regulations and
other factors, many of which are beyond the control of the Company.
Prospective investors are cautioned that any such statements are not
guarantees of future performance and that actual results or developments may
differ materially from those projected in such forward-looking statements.
 
DEPENDENCE ON ACTIVITY IN THE OIL AND GAS INDUSTRY
 
  Demand for the Company's services depends upon the condition of the oil and
gas industry and, in particular, the level of capital expenditures by oil and
gas companies for seismic data acquisition activities. These activities may be
influenced by prevailing oil and gas prices; expectations about future demand
and prices; the cost of exploring for, producing and developing oil and gas
reserves; the discovery rate of new oil and gas reserves; the availability and
cost of permits and consents from landowners to conduct seismic activity;
political and economic conditions; governmental regulations; and the
availability and cost of capital. Historically, oil and gas prices and the
level of exploration and development activity have fluctuated substantially.
Any significant decline in worldwide demand for oil and gas or prolonged
reduction in oil or gas prices in the future would likely depress exploration
and development activity and, thus, demand for seismic data. Any significant
reduction in seismic data acquisition activity in the areas where the Company
operates would result in a reduction in the demand for the Company's services
and could have a material adverse effect on the Company's financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--General--Demand."
 
SHORTAGE OF LABOR
 
  The Company's ability to remain productive and profitable depends on its
ability to attract and retain workers. The number of employees of the Company
has increased from 262 at January 1, 1996 to approximately 600 at September
30, 1997, and the Company expects that the total number of employees will
increase further in order to support the Company's anticipated growth. In
addition, the Company has historically experienced a high rate of employee
turnover. As a result, management must devote significant time, effort and
expense to hire, train and retain qualified workers. The Company believes that
there are a large number of trainable workers residing in reasonable proximity
to its facilities; however, there can be no assurance that the Company will be
successful in recruiting, training and retaining such workers due to a variety
of factors, including the potential inability or lack of desire by such
workers to either commute to the Company's facilities and job sites or
relocate to areas closer to the Company's areas of operation and competition
for workers from other industries. While the Company believes that its wage
rates are competitive and that its relationship with its workforce is good, a
significant increase in the wages paid by other employers could result in a
reduction in the Company's workforce, increases in the wage rates paid by the
Company, or both. If either of these events occur for any significant period
of time, the production and profitability of the Company could be diminished
and the growth potential of the Company could be impaired. See "Business--
Employees."
 
RISKS OF RAPID GROWTH
 
  The Company has grown rapidly over the last several years through internal
growth and acquisitions of companies engaged in activities other than seismic
drilling in the Transition Zone, the Company's traditional
 
                                       9
<PAGE>
 
line of business. Managing the rapid growth experienced by the Company will be
important for the Company's future success and will demand increased
responsibility for management personnel. Several factors, including the lack
of sufficient executive-level personnel, increased administrative burdens and
the increased logistical problems of large, expansive operations, could
present difficulties to the Company, which if not managed successfully, could
have a material adverse effect on the Company's financial condition and
results of operations.
 
ABSENCE OF COMBINED OPERATING HISTORY
 
  The Company has recently completed acquisitions of several companies whose
operations differ somewhat from the Company's traditional Transition Zone
seismic drilling operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--General--Recent Acquisitions."
These entities were operated separately prior to their acquisition by the
Company, and the Company has not fully integrated the operations of these
acquired companies with its own. No assurance can be given that the Company
will be successful in managing and incorporating these businesses into its
existing operations or that the Company will not experience difficulties or
unanticipated expenses as it seeks to integrate their operations. The
Company's failure to successfully incorporate the acquired businesses into its
existing operations, or the occurrence of unexpected costs or liabilities as a
result of these acquisitions, could have a material adverse effect on the
Company. Neither the historical nor the pro forma financial information
included herein is necessarily indicative of the results that would have been
achieved had the Company been operated on a fully integrated basis or the
results that may be realized in the future.
 
RISKS OF ACQUISITION STRATEGY
 
  Future acquisitions are a key element of the Company's growth and expansion
strategy. The Company intends to use a portion of the net proceeds of the
Offering to pursue acquisitions of other companies with operations related or
complementary to its current operations. See "Use of Proceeds." There can be
no assurance that the Company will be able to identify and acquire acceptable
acquisition candidates on terms favorable to the Company. There also can be no
assurance that the Company will successfully integrate the operations and
assets of any acquired business with its own or that the Company's management
will be able to effectively manage the increased size of the Company or
operate a new line of business. Any inability on the part of the Company to
integrate and manage acquired businesses could have a material adverse effect
on the Company's results of operations and financial condition.
 
DEPENDENCE ON SIGNIFICANT CUSTOMERS
 
  The Company's business is dependent on a relatively small number of
geophysical companies and those oil and gas companies operating in the
Transition Zone. A large portion of the Company's revenue has historically
been generated from contracts with a few geophysical companies. The Company's
four largest customers, each of which individually accounted for more than 10%
of revenue in a given year, collectively accounted for 88%, 88% and 70% of
revenue for 1994, 1995 and 1996, respectively. Therefore, the Company is
dependent upon the maintenance of strong working relationships with these
geophysical companies as well as oil and gas companies, which in many cases
participate in determining which drilling, survey or aviation company will be
used on their respective seismic projects. The loss of any significant
customer for any reason could result in a substantial loss of revenue and have
a material adverse effect on the Company's operating performance. See
"Business--Customers; Marketing; Contracting."
 
BACKLOG
 
  The Company's backlog represents those projects for which a customer has
accepted the Company's bid and has scheduled a start date for the project.
Projects currently included in the Company's backlog are subject to
termination without penalty at the option of the customer, which could
substantially reduce the amount of backlog currently reported. Termination of
a number of large projects in the Company's existing backlog could
 
                                      10
<PAGE>
 
have a material adverse effect on the Company's revenue, net income and cash
flow for 1998. As of August 31, 1997, 70% of the Company's backlog was
attributable to 22 projects for two customers. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--General--
Backlog" and "Business--Backlog."
 
SEASONALITY AND WEATHER RISKS
 
  The Company's operations are subject to seasonal variations in weather
conditions and daylight hours. Since the Company's activities take place
outdoors, the average number of hours worked per day, and therefore the number
of holes drilled or surveyed per day, generally is less in winter months than
in summer months, due to an increase in rainy, foggy and cold conditions and a
decrease in daylight hours. Furthermore, demand for seismic data acquisition
activity by oil and gas companies in the first quarter is generally lower than
at other times of the year. As a result, the Company's revenue and gross
profit during the first quarter of each year are typically low as compared to
the other quarters. Operations may also be affected by rainy weather,
lightning, hurricanes and other storms prevalent along the Gulf Coast
throughout the year and by seasonal climatic conditions in the Rocky Mountain
area. In addition, prolonged periods of dry weather result in slower drill
rates in marsh and swamp areas as water in the quantities needed to drill is
more difficult to obtain and equipment movement is impeded. Adverse weather
conditions and dry weather could increase maintenance costs for the Company's
equipment and decrease the number of vehicles available for operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--General--Seasonality and Weather" and "Business--Seasonality and
Weather Risks."
 
OPERATING RISKS
 
  The Company's operations are conducted under hazardous conditions in
difficult terrain that is not easily accessible. Accordingly, its operations
are subject to risks of injury to or death of personnel and loss of equipment.
The Company's aviation division is subject to numerous hazards inherent in the
operation of helicopters and airplanes, such as adverse weather conditions,
crashes, collisions and fires, all of which may result in injury to or death
of personnel or losses of equipment and revenues. The Company maintains hull
and liability insurance which generally insures the Company against certain
legal liabilities to others, as well as to damage to its equipment and
aircraft. The Company also maintains general liability insurance policies that
protect it against liabilities that may be incurred in the ordinary course of
its business. There can be no assurance, however, that the Company's insurance
coverage will be adequate to cover any future losses that may occur, that the
Company will be able to maintain its existing coverages or that the premiums
therefor will not increase substantially. The Company does not carry business
interruption insurance for any of its operations. See "Business--Insurance."
 
COMPETITION
 
  The Company currently competes with several other providers of seismic
drilling, survey and aviation support services. Because of the size of its
fleet of specialized transportation and seismic drilling equipment, the
Company occupies a market leadership position in the seismic drilling market
in the Transition Zone. However, there are few barriers to entry in the
seismic drilling market, and an increase in competition in the market could
arise from new ventures, expanded operations of existing competitors, an
increase in seismic drilling by geophysical companies or otherwise. Increased
competition in the seismic drilling market in the Transition Zone could have a
material adverse effect on the Company's revenue, gross profit and net income.
 
TECHNICAL EVOLUTION
 
  The market for seismic data is characterized by continual technological
developments that have resulted in, and likely will continue to result in,
substantial improvements in the methods of obtaining seismic information and
the scope and quality of seismic information. Whether the Company can continue
to develop equipment and provide seismic services to meet evolving industry
standards and practice, and achieve levels of capability and
 
                                      11
<PAGE>
 
price that are acceptable to its customers, will be significant factors in
determining the Company's ability to compete. There also can be no assurance
that the geophysical industry will not develop new methods of seismic data
acquisition that do not require the same seismic drilling and support services
currently offered by the Company. If the Company is unable, for technological
or other reasons, to continue to develop competitive equipment and services in
response to changes in the seismic drilling and support services market, its
results of operations and financial condition could be materially adversely
affected.
 
RISKS OF INTERNATIONAL EXPANSION
 
  To the extent the Company's future operations involve international
expansion, those operations would be subject to a number of risks inherent in
business operations in foreign countries, including political, social and
economic instability, potential seizure or nationalization of assets, currency
restrictions and exchange rate fluctuations, nullification, modification or
renegotiation of contracts, import-export quotas and other forms of public and
governmental regulation, all of which would be beyond the control of the
Company. Additionally, the ability of the Company to compete in international
markets may be adversely affected by import duties and fees, foreign taxes,
foreign governmental regulations that favor or require the awarding of
contracts to local contractors or regulations requiring foreign contractors to
employ citizens of or purchase supplies from a particular jurisdiction.
 
REGULATORY AND ENVIRONMENTAL MATTERS
 
  The Company's operations and properties are subject to and affected by
various types of governmental regulation, including laws and regulations
governing the entry into and restoration of wetlands, the handling of
explosives, the operation of commercial aircraft and numerous other federal,
state and local laws and regulations. In addition, the Company's operations
require current licenses from various state, local and federal agencies,
including the Federal Aviation Administration ("FAA") and the Bureau of
Alcohol, Tobacco and Firearms of the U.S. Department of Justice ("ATF").
Violations of various statutory and regulatory programs that apply to the
Company's operations can result in civil penalties, remediation expenses,
monetary damages, potential injunctions, cease and desist orders and criminal
penalties. Some environmental statutes impose strict liability, rendering a
person liable for environmental damage without regard to negligence or fault
on the part of such person. To date the Company's cost of complying with such
laws and regulations has not been material, but because such laws and
regulations are changed frequently, it is not possible for the Company to
accurately predict the cost or impact of such laws and regulations on its
future operations. In addition, the loss by the Company of any of the licenses
required for its operations for any reason could have a material adverse
effect on the Company's operations.
 
  The Company depends on the demand for its services from the oil and gas
industry and is affected by changing taxes, price controls and other laws and
regulations relating to the oil and gas industry generally. The adoption of
laws and regulations curtailing exploration and development drilling for oil
and gas in the Company's areas of operations for economic, environmental or
other policy reasons would adversely affect the Company's operations by
limiting demand for its services. The Company cannot determine to what extent
future operations and earnings of the Company may be affected by new
legislation, new regulations or changes in existing regulations. See
"Business--Governmental Regulation."
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's success depends on, among other things, the continued active
participation of David A. Jeansonne, Chairman of the Board and Chief Executive
Officer, Roger E. Thomas, President, and certain of the Company's other
officers and key operating personnel. The loss of the services of any one of
these persons could have a material adverse effect on the Company. The Company
has entered into employment agreements with each of its executive officers,
including Messrs. Jeansonne (through June 2003) and Thomas (through July
1999), and has purchased "key-man" life insurance with respect to Mr.
Jeansonne. See "Management."

SUBSTANTIAL CONTROL BY EXISTING SHAREHOLDER
 
  Upon completion of the Offering, Advantage Capital Corporation, together
with certain of its affiliates (collectively, "Advantage Capital"), will
beneficially own approximately 50.2% (48.6% if the over-allotment option is
exercised in full) of the issued and outstanding shares of Common Stock. In
addition, two members of the Company's Board of Directors are affiliates of
Advantage Capital. The stock ownership and current board representation of
Advantage Capital gives it the ability to control the election of the
Company's directors and other corporate matters requiring shareholder approval
and exert significant influence over the business and affairs of the Company.
This may have the effect of delaying or preventing a change in control of the
Company. The interests of Advantage Capital may not always be the same as the
interests of the Company's other shareholders. See "Principal Shareholders."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of the Offering, the Company will have outstanding
15,500,000 shares of Common Stock (excluding 1,090,018 shares issuable upon
the exercise of outstanding options). All of the 3,500,000 shares of Common
Stock offered hereby will be eligible for sale in the public market without
restriction upon completion of the Offering. All of the remaining outstanding
shares of Common Stock are "restricted securities" as that term is defined in
Rule 144 under the Securities Act of 1933, as amended (the "Securities Act").
The Company, Advantage Capital and each of the Company's directors and
executive officers have agreed not to offer, sell or otherwise dispose of any
shares of Common Stock in the public market for 180 days from the date of this
Prospectus without the prior written consent of Lehman Brothers Inc. See
"Underwriting." In addition, none of the 12,000,000 shares of Common Stock
held by existing shareholders will be eligible for resale pursuant to Rule 144
until one year from the date of the Share Exchange. Although the Company
cannot predict the timing or amount of future sales of Common Stock or the
effect that the availability of such shares for sale will have on the market
price prevailing from time to time, sales of substantial amounts of Common
Stock in the public market following this Offering, including sales in
connection with a registered offering of Common Stock, could adversely affect
the market price of the Common Stock. See "Principal Shareholders" and "Shares
Eligible for Future Sale."
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF MARKET PRICE
 
  Prior to the Offering, there has been no public market for the Common Stock.
Although application has been made to list the Common Stock offered hereby on
the Nasdaq National Market, there can be no assurance that a market for the
Common Stock will develop or, if developed, will be sustained. The initial
public offering price of the Common Stock will be determined by negotiations
between the Company and the Underwriters. For the factors considered in such
negotiations, see "Underwriting." There can be no assurance that future market
prices at which the Common Stock will sell in the public market after the
Offering will not be lower than the initial public offering price. Following
the Offering, the market price of the Common Stock may fluctuate depending on
various factors, including the general economy, stock market conditions,
general trends in the seismic business, fluctuations in oil and gas prices,
announcements by the Company or its competitors and variations in the
Company's quarterly and annual operating results.
 
DILUTION
 
  Purchasers of the Common Stock offered hereby will incur immediate dilution
of $10.94 per share in the pro forma net tangible book value of their
investment (assuming an initial public offering price of $14.00 per share).
See "Dilution."
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION,
BY-LAWS AND LOUISIANA BUSINESS CORPORATION LAW
 
  Certain provisions of the Company's Articles of Incorporation and By-laws
and of the Louisiana Business Corporation Law may tend to deter potential
unsolicited offers or other efforts to obtain control of the Company
 
                                      13
<PAGE>
 
that are not approved by the Board of Directors. Such provisions may therefore
deprive the shareholders of opportunities to sell shares of Common Stock at a
premium to then prevailing market prices in connection with a takeover
attempt. See "Description of Capital Stock--Certain Charter and By-law
Provisions."
 
LIMITATIONS ON FOREIGN OWNERSHIP OF COMPANY STOCK
 
  Under the Federal Aviation Administration Authorization Act of 1994, as
amended (the "Federal Aviation Act"), it is unlawful to operate certain
commercial aircraft for hire within the United States unless such aircraft are
registered with the FAA and the operator of such aircraft has been issued an
operating certificate by the FAA. As a general rule, aircraft may be
registered under the Federal Aviation Act only if the aircraft is owned or
controlled by one or more citizens of the United States, and an operating
certificate may be granted only to a citizen of the United States. For
purposes of these requirements, a corporation is deemed to be a citizen of the
United States only if, among other things, at least 75% of the voting interest
therein is owned or controlled by United States citizens. To assure the
Company's continued ability to operate commercial aircraft in the United
States, the Company's Articles of Incorporation contain provisions designed to
assure that not more than 24% of the outstanding shares of Common Stock are
owned by persons who are not U.S. citizens. The Articles of Incorporation
provide that any transfer or purported transfer of shares of Common Stock that
would result in the ownership by persons who are not U.S. citizens of more
than 24% of the then outstanding shares of Common Stock would not become
effective against the Company, and the Company would have the power to deny
voting and dividend rights with respect to such shares. See "Business--
Governmental Regulation--Aviation" and "Description of Capital Stock--
Limitation on Foreign Ownership of Company Stock."
 
DIVIDENDS
 
  The Company currently intends to retain earnings, if any, to meet its
working capital requirements and to finance the future operation and growth of
the Company's business and, therefore, does not plan to declare or pay cash
dividends to holders of its Common Stock in the foreseeable future. See
"Dividend Policy."

                                  THE COMPANY
 
  The Company was originally founded in 1987 by its Chairman and Chief
Executive Officer, David A. Jeansonne, as OMNI Drilling Corporation ("OMNI
Drilling"), to provide drilling services to the geophysical industry. In 1995,
Mr. Jeansonne and R. Patrick Morris, the Company's Vice President and General
Manager of the Aviation Division, formed American Aviation to provide long-
line helicopter services to the geophysical industry.
 
  In July 1996, OMNI Geophysical was formed to facilitate the OGC Acquisition,
pursuant to which OMNI Geophysical acquired substantially all of the assets of
OGC, the successor to the business of OMNI Drilling. In July 1997, OMNI
Geophysical also acquired substantially all of the assets of American
Aviation.
 
  The Company was formed on September 11, 1997, solely to facilitate the
Offering. Immediately prior to the Offering, the holders of the common units
of OMNI Geophysical will effect the Share Exchange, pursuant to which such
holders will exchange all of the 113,476 outstanding common units in OMNI
Geophysical for 12,000,000 shares of Common Stock and the holders of
outstanding options to purchase common units of OMNI Geophysical will receive
options to purchase a corresponding number of shares of Common Stock. Prior to
the Share Exchange, OMNI Geophysical will effect the Preferred Unit Repurchase
pursuant to which it will repurchase all of its outstanding preferred units
for $5.0 million. See "Certain Transactions."
 
  The Company's principal executive offices are located at 4484 NE Evangeline
Thruway, Carencro, Louisiana, 70520, its mailing address is P.O. Box 3761,
Lafayette, Louisiana 70502 and its telephone number is (318) 896-6664.
 
                CHANGE IN TAX STATUS AND RELATED DISTRIBUTIONS
 
  Since its inception, OMNI Geophysical has been treated as a partnership for
federal and state income tax purposes. As a limited liability company, OMNI
Geophysical is not subject to income tax at the entity level and its income is
reportable by its members on their personal income tax returns, whether or not
earnings and profits are distributed to its members. As a result, the members
of OMNI Geophysical have paid or will incur federal and state income tax
liabilities on all earnings of OMNI Geophysical through the date of the Share
Exchange. Following the Share Exchange, the operations of OMNI Geophysical
will be conducted by the Company, and its earnings will be subject to
corporate level taxation.
 
  Prior to the Share Exchange, all of the undistributed earnings of OMNI
Geophysical through the date of the Share Exchange will be distributed to the
members of OMNI Geophysical in the LLC Distribution. At June 30, 1997, OMNI
Geophysical's undistributed earnings totaled approximately $3.7 million.
Management estimates that the Company will have additional undistributed
earnings of approximately $      million, for an aggregate of $      million,
at the time of the Share Exchange (assuming the Share Exchange is consummated
on          , 1997). Purchasers of Common Stock in the Offering will not
receive any portion of the LLC Distribution.
 
  The LLC Distribution will be funded with the proceeds of a $10.0 million
term loan from Hibernia National Bank bearing interest at the London Interbank
Offered Rate ("LIBOR") plus 1.0% which will be secured by the cash distributed
in the LLC Distribution. Following completion of the Offering, amounts
outstanding under this loan are expected to be repaid with the proceeds of a
new term loan or revolving credit facility to be entered into by the Company
upon completion of the Offering. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Certain Transactions."
 
  OGC historically made cash distributions to its shareholders in order to
provide such shareholders with a cash return and to fund federal and state
income tax liabilities payable by such shareholders that resulted from OGC's
status as an S corporation. OGC distributed $765,250 and $881,200,
respectively, in the year ended December 31, 1995 and the 201-day period ended
July 19, 1996. OMNI Geophysical made distributions to its members totaling
$18,810 during the 165-day period ended December 31, 1996 and $572,858 since
January 1, 1997 in order to fund federal and state tax liabilities payable by
its members. See "Certain Transactions."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of Common Stock offered
hereby, after deducting underwriting discounts and commissions and estimated
offering expenses, will be approximately $44.9 million, assuming an initial
public offering price of $14.00 per share ($51.8 million if the Underwriters'
over-allotment option is exercised in full). The Company intends to use
approximately $33.4 million of the net proceeds to repay the following
indebtedness (including prepayment penalties and accrued interest thereon):

(a) Bears interest at the London Interbank Offered Rate ("LIBOR") plus 3.0%.
    Consists of five notes that mature on December 1, 2001, February 1, 2002,
    March 1, 2002, May 1, 2002 and August 1, 2002, respectively. Proceeds from
    these loans were used to purchase, and the notes are collateralized by,
    various seismic drilling and support equipment. The Company will incur a
    prepayment penalty of 2.0% of the outstanding balance at the time it
    repays the indebtedness (approximately $93,000).
(b) Matures on January 3, 2000. Proceeds from this loan were used to
    consolidate financing incurred to purchase 43 trucks, which serve as
    collateral for the loan.
(c) Of the principal outstanding, $5,361,437 bears interest at LIBOR plus
    3.75% (the "Variable Rate") and matures on July 19, 2001. Prior to August
    19, 1998, the Company can elect to pay interest on this portion of the
    loan at a fixed rate equal to the interest rate on U.S. Treasury
    securities of a comparable maturity to the loan at the time of election
    plus 4.25% (the "Fixed Rate"). The Company will incur a prepayment penalty
    of up to 5% (up to $268,072) of the amount of indebtedness prepaid,
    depending on the date of prepayment. The proceeds of this portion of the
    loan were used to finance the OGC Acquisition, and the assets acquired
    serve as collateral for the loan.
  The loan agreement was amended on September 19, 1997 to provide an
  additional commitment of an aggregate of up to $4,000,000 or 90% of the
  cost of the collateral securing amounts advanced under this amendment.
  Amounts advanced under this amendment bear interest at LIBOR plus 3.0%. The
  Company will incur a prepayment penalty of 2.0% of the outstanding balance
  at the time it repays the indebtedness. Amounts advanced pursuant to this
  amendment are collateralized by various seismic drilling and support
  equipment.
(d) Matures on April 1, 2000. Proceeds of this loan were used to finance three
    years of the Company's insurance premiums.
(e) Consists of 22 separate motor vehicle loans incurred to purchase 34
    trucks, which serve as collateral for the loans. The loans range in
    maturity from September 17, 1999 to September 17, 2000 and bear interest
    at 9.0% except for one loan of $18,933 which bears interest at 8.5%.
 
                                      16
<PAGE>
 
(f) Bears interest at the lesser of the prime rate as quoted from time to time
    by Citibank, N.A. New York ("Citibank Prime") plus 0.5% or LIBOR plus 3.5%
    and matures on August 1, 1998. The revolving line of credit provides up to
    $8.0 million (subject to a borrowing base limitation of 80% of eligible
    trade receivables) that can be used for general working capital
    requirements and the issuance of letters of credit. The loan is secured by
    the Company's accounts receivable, general intangibles and its Carencro
    facilities. In addition, the Company has granted Hibernia National Bank a
    mortgage on the 34 acres of land it owns adjacent to its Carencro
    facility. This mortgage also secures the loans described in notes (g) and
    (h).
(g) Bears interest at the lesser of Citibank Prime plus 0.75% or LIBOR plus
    3.75% and matures five years after conversion to a term loan upon
    completion of construction. As of September 30, 1997, the Company had not
    borrowed under this loan but expects to borrow the entire $2.6 million
    prior to the completion of the Offering. Proceeds will be used to finance
    a portion of the construction of the Company's new administrative and
    fabrication and maintenance buildings, which collateralize the loan.
(h) Bears interest at the lesser of Citibank Prime plus 0.5% or LIBOR plus
    3.0% and matures on August 6, 2002. Proceeds of this loan were used to
    fund a portion of the purchase price for substantially all of the assets
    of American Aviation. The loan is collateralized by the assets of the
    Company's aviation division. The Company will incur a prepayment penalty
    of 1.0% of the prepayment amount (approximately $67,000).
(i) Matures on June 30, 2001. This promissory note was issued to OGC as part
    of the consideration for the OGC Acquisition. See "Certain Transactions."
(j) Payable on demand. This promissory note was issued in connection with the
    acquisition of substantially all of the assets of American Aviation.
(k) Matures on July 1, 1998. Proceeds were used to finance one year of
    premiums for seven of the Company's insurance policies.
 
  The Company will use the remainder of the estimated net proceeds
(approximately $11.5 million) for general corporate purposes, including
acquisitions, capital expenditures and working capital. Pending application of
the net proceeds, the Company intends to invest the net proceeds in short-
term, investment-grade, interest-bearing securities.
 
                                DIVIDEND POLICY
 
  After the Offering, the Company intends to retain earnings, if any, to meet
its working capital requirements and to finance the future operations and
growth of its business and, therefore, does not plan to declare or pay cash
dividends to holders of its Common Stock in the foreseeable future. In
addition, the ability of the Company to make distributions to its shareholders
will be restricted by its credit agreements. See "Risk Factors--Dividends."

                                   DILUTION
 
  Dilution is the difference between the initial public offering price per
share of the Common Stock offered hereby and the pro forma tangible book value
per share value of the Common Stock after giving effect to the Offering. Pro
forma net tangible book value per share of Common Stock represents the amount
of the Company's tangible net worth (total tangible assets less total
liabilities) divided by the total number of shares of Common Stock
outstanding. After giving effect to the Share Exchange and the LLC
Distribution, the pro forma net tangible book value of the Company at July 31,
1997 would have been $2.6 million, or $0.21 per share of Common Stock. After
giving effect to the Offering (assuming an initial public offering price of
$14.00 per share and deducting the underwriting discounts and commissions and
offering expenses estimated to be $4.1 million), the pro forma net tangible
book value of the Company at July 31, 1997 would have been approximately $47.5
million or $3.06 per share of Common Stock. This represents an immediate
increase in net tangible book value of $2.85 per share of Common Stock to
current holders of Common Stock and an immediate dilution of approximately
$10.94 per share to the new investors purchasing shares in the Offering.
 
  The following table illustrates this per share dilution to new investors:

(a) The step-up to fair value of the assets acquired in the OGC Acquisition
    resulted in increased depreciation reported by OMNI Geophysical, which is
    included in operating expenses. In order to finance the OGC Acquisition,
    OMNI Geophysical incurred additional indebtedness, which resulted in
    additional interest expenses being reported.
(b) Each of OGC and OMNI Geophysical is or was an S corporation or a limited
    liability company exempt from income tax at the entity level, and thus the
    historical financial statements show no provision for income taxes. The
    Company, however, is a corporation that will pay income taxes at the
    corporate level. This pro forma adjustment reflects a provision for income
    taxes on the Company's net income at a combined federal and state tax rate
    of 40%. See "Change in Tax Status and Related Distributions."
(c) Gives effect to (i) the Share Exchange, (ii) the payment of dividends on
    the outstanding preferred units of OMNI Geophysical of approximately
    $180,000 for the 165-day period ended December 31, 1996 and $172,000 for
    the six months ended June 30, 1997, and (iii) the exercise of options to
    purchase 118,018 shares of Common Stock granted to employees of the
    Company outside of the Company's Stock Incentive Plan, as if each had
    occurred as of the beginning of the period. See "The Company."
(d) The Company calculates EBITDA (earnings before interest expense, income
    taxes, depreciation and amortization) as operating income plus
    depreciation and amortization. EBITDA should not be considered as an
    alternative to net income or any other measure of operating performance
    determined in accordance with general accounting principles. EBITDA is
    widely used by financial analysts as a measure of financial performance.
    The Company's measurement of EBITDA may not be comparable to similarly
    titled measures reported by other companies.
(e) Includes the stepped-up fair value of the assets and liabilities purchased
    in the OGC Acquisition.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
historical consolidated financial statements, the pro forma consolidated
financial statements and the related notes thereto included elsewhere in this
Prospectus. The following information contains certain forward-looking
statements, which are subject to risks and uncertainties that could cause
actual results to differ materially from those expressed in or implied by the
statements.
 
GENERAL
 
  Demand. Demand for the Company's services is principally affected by
conditions affecting geophysical companies engaged in the acquisition of 3-D
seismic data. The level of activity among geophysical companies is primarily
affected by the level of capital expenditures by oil and gas companies for
seismic data acquisition activities. A number of factors influence the
decision of oil and gas companies to pursue the acquisition of seismic data,
including (i) prevailing and expected oil and gas demand and prices; (ii) the
cost of exploring for, producing and developing oil and gas reserves; (iii)
the discovery rate of new oil and gas reserves; (iv) the availability and cost
of permits and consents from landowners to conduct seismic activity; (v) local
and international political and economic conditions; (vi) governmental
regulations; and (vii) the availability and cost of capital. The ability to
finance the acquisition of seismic data in the absence of oil and gas
companies' interest in obtaining the information is also a factor as some
geophysical companies will acquire seismic data on a speculative basis.
Onshore 3-D seismic data acquisition activity has substantially increased over
the past few years; however, any significant reduction in seismic exploration
activity in the areas where the Company operates would result in a reduction
in the demand for the Company's services and could have a material adverse
effect on the Company's financial condition and results of operations. See
"Risk Factors--Dependence on Activity in the Oil and Gas Industry."
 
  Within the last decade, improvements in drilling and production techniques
and the acceptance of 3-D imaging as an exploration tool have resulted in
significantly increased seismic activity throughout the Transition Zone. Due
to this increased demand, the Company has significantly increased its capacity
as measured by drilling units, support equipment and employees. The additional
capacity and related increase in work force have led to significant increases
in the Company's revenue and generally commensurate increases in operating
expenses and selling, general and administrative expenses. Management expects
these expenses to continue to increase as a direct correlation to anticipated
increases in seismic activity.
 
  Backlog. Most of the Company's seismic drilling projects are awarded
pursuant to a competitive bidding process. Once the Company's bid on a
particular project has been accepted and a start date for the project has been
scheduled, the Company will include the project in its backlog. As of August
31, 1997, the Company's backlog was $61.2 million, compared to $29.6 million
at August 31, 1996. Projects currently included in the Company's backlog are
subject to termination without penalty at the option of the customer, which
could substantially reduce the amount of backlog currently reported and the
revenue generated from the backlog. Historically, the Company has not
experienced a large volume of project terminations, and those projects that
have been terminated have typically been replaced by unscheduled projects.
Nevertheless, termination of a number of large projects in the Company's
existing backlog could have a material adverse effect on the Company's
revenue, net income and cash flow. See "Risk Factors--Backlog" and "Business--
Backlog."
 
  Revenue Recognition. The Company recognizes revenue as services are
rendered. Revenue from the Company's drilling operations is recognized on a
per hole basis. Once the Company has drilled and loaded a source point,
revenue from the drilling of such source point is recognized. Similarly,
revenue is recognized from the Company's seismic survey operations when the
source or receiving point is marked by one of the Company's survey crews. The
Company's aircraft, which are generally chartered for a guaranteed minimum
number of hours per day, generate revenue pursuant to a fixed hourly rate. It
is the general policy of the Company to invoice its customers twice a month.
 
                                      22
<PAGE>
 
  Seasonality and Weather. The Company's operations are subject to seasonal
variations in weather conditions and daylight hours. Since the Company's
activities take place outdoors, the average number of hours worked per day,
and therefore the number of holes drilled or surveyed per day, is generally
less in the winter months than in summer months. Furthermore, demand for
seismic data acquisition activity by oil and gas companies in the first
quarter is generally lower than at other times of the year. In addition, the
Company's operations in the Rocky Mountain area are subject to the seasonal
climatic conditions of that area. As a result, the Company's revenue and gross
profit during the first quarter of each year are typically less as compared to
the other quarters.
 
  Recent Acquisitions. In 1997, the Company completed several acquisitions
which have expanded both the scope and size of its seismic support operations.
The following table sets forth information with respect to these acquisitions:

drilling services in the Rocky Mountain area and in the fabrication, export
and servicing of heli-portable and other seismic drilling units. The
acquisition of American Helicopter is anticipated to occur on or before
January 31, 1998. There can be no assurance that a binding contract relating

RESULTS OF OPERATIONS
 
  The following discussion provides information related to the results of
operations of OMNI Geophysical. OMNI Geophysical acquired substantially all of
the assets and liabilities of OGC in the OGC Acquisition on July 19, 1996. The
OGC Acquisition was accounted for as a purchase with the assets acquired and
liabilities assumed recorded at their estimated fair value. As a result of
borrowings incurred to finance the OGC Acquisition and the write up of the
fixed assets purchased from OGC to their fair value at the time of the OGC
Acquisition, the Company has experienced higher interest, depreciation and
amortization expense since July 19, 1996. The historical results of operations
discussed below analyze the results of operations of OGC for the periods prior
to July 19, 1996 and the results of operations of OMNI Geophysical for the
periods after July 19, 1996. Because the effect of the OGC Acquisition is to
reduce the comparability of results of operations before and after July 19,
1996 for the reasons discussed above, and because the historical comparisons
presented below include periods that are not comparable due to different
lengths and the effect of seasonality, management is also

</TABLE>
 
  Pro forma operating revenues increased 65%, from $12.7 million in 1995 to
$21.0 million in 1996, primarily due to an increase in industry demand for 3-D
seismic data in the Transition Zone and to the Company's increased capacity as
measured by drilling units and support equipment. The Company had
approximately 40 drilling units and 32 support equipment units at December 31,
1995 compared to 57 drilling units and 55 support equipment units at December
31, 1996. The Company employed 262 employees for both field and administrative
operations at December 31, 1995 compared to 522 at December 31, 1996, a 99%
increase.
 
  Pro forma operating expenses increased 73%, from $8.8 million in 1995 to
$15.2 million in 1996, due to the increase in the volume of the Company's
operations from 1995 to 1996. Repair and maintenance costs increased 25%, from
$1.6 million in 1995 to $2.0 million in 1996, primarily due to the increase in
the use of the Company's seismic drilling and transportation equipment. Total
operating labor costs increased 49%, from $4.1 million in 1995 to $6.1 million
in 1996, due to the large increase in the number of employees needed to meet
the increased demand for the Company's services. Explosive costs increased
550%, from $0.2 million in 1995 to $1.3 million in 1996, primarily due to an
increase in the number of projects for which the Company provided explosives
and a 6% increase in the price of explosives. Fuel costs increased 60%, from
$0.5 million in 1995 to $0.8 million in 1996, due to the increased number and
usage of the Company's drilling and support units. Contract drilling services
costs increased 67%, from $0.3 million in 1995 to $0.5 million in 1996, as the
Company occasionally had to subcontract for equipment and services, including
drilling units and personnel, to meet the increased demand. Equipment rentals
increased 200%, from $0.2 million in 1995 to $0.6 million in 1996.
 
  Pro forma gross profit increased 49%, from $3.9 million in 1995 compared to
$5.8 million in 1996; however, gross profit margins fell from 31% in 1995 to
28% in 1996, primarily due to the increase in the number of projects for which
the Company provided explosives, as the Company receives lower margins on
explosives than it does from its other operations.
 
  Pro forma general and administrative expenses increased 64%, from $1.1
million in 1995 to $1.8 million in 1996, primarily due to an increase in
office personnel and insurance costs. Insurance costs increased 100%, from
$0.2 million in 1995 to $0.4 million in 1996, due to expanded coverage and
increased limits of liability on existing policies. Total general and
administrative expense as a percentage was 9% in both 1995 and 1996.
 
                                      24
<PAGE>
 
  Pro forma interest expense remained unchanged at $0.9 million in 1995 and
1996. A decrease in the interest rates charged on current and long-term debt
from 1995 to 1996 offset the higher debt levels experienced by the Company in
1996. At December 31, 1995, the interest rates on then existing debt ranged
from 8.25% to 11%. At December 31, 1996, the interest rates on the Company's
revolving line of credit, the debt used for the OGC Acquisition and the
subordinated debt issued in connection with the OGC Acquisition were 9.25%,
9.37% and 8.5%, respectively.
 
 Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
  Operating revenues increased 93%, from $8.8 million in the first six months
of 1996 to $17.0 million in the first six months of 1997, primarily due to the
increase in industry demand for 3-D seismic data and to the Company's
increased capacity as measured by drilling units and support equipment. The
Company had approximately 41 drilling units and 32 support equipment units at
June 30, 1996 compared to 87 drilling units and 75 support equipment units at
June 30, 1997. The Company employed 300 employees for both field and
administrative operations at June 30, 1996 compared to 439 at June 30, 1997, a
46% increase. The Company's newly formed survey division generated
approximately $300,000 in revenue during the first six months of 1997.
 
  Operating expenses increased 105%, from $6.0 million in the first six months
of 1996 to $12.3 million in the first six months of 1997. Repair and
maintenance costs increased 100%, from $0.9 million in the first six months of
1996 to $1.8 million in the first six months of 1997, primarily due to the
increase in the use of the Company's seismic drilling and transportation
equipment. Total operating labor costs increased 100%, from $2.5 million in
the first six months of 1996 to $5.0 million in the first six months of 1997,
primarily due to the significant increase in the Company's workforce.
Explosive costs increased 100%, from $0.7 million in the first six months of
1996 to $1.4 million in the first six months of 1997, due primarily to an
increase in the number of projects for which the Company provided explosives.
Depreciation expense increased 300%, from $0.2 million in the first six months
of 1996 to $0.8 million in the first six months of 1997, due to the increased
number of seismic drilling and support equipment units and the stepped-up
basis in such units that resulted from the OGC Acquisition. In addition, due
to the increased volume of the Company's operations, supplies expense
increased 80% from $0.5 million in the first six months of 1996 to $0.9
million in the first six months of 1997.
 
  Gross profit increased 68%, from $2.8 million in the first six months of
1996 to $4.7 million in the first six months of 1997; however, gross profit
margins fell from 32% in the first six months of 1996 to 28% in the first six
months of 1997, primarily due to the start-up costs of $0.4 million related to
the survey division and an increase in depreciation expense due to the step-up
in value of equipment acquired from OGC.
 
  General and administrative expenses increased 114%, from $0.7 million in the
first six months of 1996 to $1.5 million in the first six months of 1997,
primarily due to additions of office personnel to support the Company's
expanded operations; however, general and administrative expenses, as a
percentage of revenues, increased from 8% in the first six months of 1996 to
9% in the first six months of 1997. Payroll, insurance and payroll taxes
increased 80%, from $0.5 million in the first six months of 1996 to $0.9
million in the first six months of 1997.
 
  Interest expense increased 500%, from $0.1 million in the first six months
of 1996 to $0.6 million in the first six months of 1997, due to the increase
in borrowings to fund the acquisition of additional drilling units and support
equipment and debt incurred in connection with the OGC Acquisition.
 
 165-day Period Ended December 31, 1996 Compared to 201-day Period Ended July
19, 1996
 
  Operating revenues increased 9%, from $10.0 million in the 201-day period
ended July 19, 1996 (the "201-day period") to $10.9 million in the 165-day
period ended December 31, 1996 (the "165-day period"), primarily due to the
increase in demand for the Company's seismic drilling services. In order to
meet this continued increased demand, the Company fabricated or purchased an
additional 14 drilling units and 14 support equipment
 
                                      25
<PAGE>
 
units during the 165-day period, which enabled the Company to record increased
revenue despite the differences in the length of the two periods. In addition,
as mentioned previously, drilling revenues are typically higher in the summer
and fall months due to favorable weather conditions for Transition Zone
drilling services.
 
  Operating expenses increased 19%, from $6.8 million in the 201-day period to
$8.1 million in the 165-day period. Other operating expenses, with the
exception of depreciation expense, generally increased commensurate with the
increase in seismic drilling services provided by the Company. Depreciation
expense increased 133%, from $0.3 million in the 201-day period to $0.7
million in the 165-day period, due to the step-up of the basis of the
Company's assets that resulted from the OGC Acquisition.
 
  Gross profit declined from $3.2 million for the 201-day period to $2.8
million for the 165-day period due primarily to the increase in depreciation
expense discussed above.
 
  General and administrative expenses as a percent of revenue increased from
8% for the 201-day period to 9% for the 165-day period, due primarily to the
increase in office personnel needed to support the increased scope of the
Company's operations.
 
  Interest expense increased from $0.2 million for the 201-day period to $0.4
million for the 165-day period due to the additional financing costs
associated with the OGC Acquisition and the increase in borrowings to fund
purchases and construction of new drilling units and support equipment.
 
 201-day Period Ended July 19, 1996 Compared to Year Ended December 31, 1995
 
  Operating revenues for the 201-day period were $10.0 million compared to
$12.7 million for the year ended December 31, 1995. The decline in revenue was
due entirely to the shorter time period of the 201-day period as compared to a
full year in 1995, as demand for the Company's seismic drilling services
continued to increase in the 201-day period.
 
  Operating expenses also declined due to the shorter period. Gross profit
margin was 31% for 1995 compared to 32% for the 201-day period.
 
  General and administrative expenses as a percentage of revenues were 14% for
1995 compared to 8% for the 201-day period. This decrease was primarily
attributable to a reduction in the bonuses paid to certain employees.
 
  Interest expense was approximately the same for both periods, although on an
annualized basis interest expense increased due to the additional borrowings
incurred to expand the number of drilling units and support equipment units
during the later half of 1995 and the 201-day period.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Operating revenue increased 74%, from $7.3 million in 1994 to $12.7 million
in 1995. The increase was due to an increase in industry demand for 3-D
seismic data in the Transition Zone. The Company was able to absorb a large
portion of the increase in seismic drilling demand because of the size and
variety of its drilling units and support equipment. In response to the
increased demand for 3-D seismic data, the Company increased its capacity by
buying and building additional drilling units and support equipment. The
Company added six drilling units and 11 support equipment units during 1995.
 
  Operating expenses increased 74%, from $5.0 million in 1994 to $8.7 million
in 1995. This increase was primarily attributable to increases in labor costs,
repairs and maintenance, depreciation, fuel expense, and supplies expense.
Total operating labor costs increased 77%, from $2.2 million in 1994 to $3.9
million in 1995, primarily due to a significant increase in the number of
employees. Repair and maintenance costs increased 60%, from $1.0 million in
1994 to $1.6 million in 1995, primarily due to the increase in the use of the
Company's
 
                                      26
<PAGE>
 
seismic drilling and transportation equipment. Depreciation expense increased
100%, from $0.2 million in 1994 to $0.4 million in 1995, due to the increased
number of drill and support equipment units. Fuel expense increased 67%, from
$0.3 million in 1994 to $0.5 million in 1995. Supplies expense increased 60%,
from $0.5 million in 1994 to $0.8 million in 1995.
 
  Gross profit increased 82%, from $2.2 million in 1994 to $4.0 million in
1995, representing gross profit margins of 30% in 1994 and 31% in 1995.
 
  General and administrative expenses increased 64%, from $1.1 million in 1994
to $1.8 million in 1995. This increase of $0.7 million was primarily due to
increases in salaries, wages, and employee benefits and insurance. Insurance
expense increased 100%, from $0.1 million in 1994 to $0.2 million in 1995, due
to expanded coverage and increased limits of liability on existing policies.
Salaries, wages and employee benefits increased 71%, from $0.7 million in 1994
to $1.2 million in 1995, primarily as a result of executive bonuses. These
increases were only slightly offset by a $0.1 million decrease in consulting
fees.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At June 30, 1997, the Company had approximately $2.0 million in cash as
compared to approximately $39,000 and $300,000 at December 31, 1996 and 1995,
respectively. The Company had working capital of approximately $5.3 million at
June 30, 1997 as compared to approximately $1.6 million and $1.0 million at
December 31, 1996 and 1995, respectively. The increase in working capital was
primarily due to increased cash and accounts receivable. Cash generated from
operations was $1.1 million for the six months ended June 30, 1997 as compared
to $0.6 million for the 165-day period ended December 31, 1996, $1.5 million
for the 201-day period ended July 19, 1996 and $1.8 million for the year ended
December 31, 1995.
 
  Existing Indebtedness. The Company's existing debt arrangements include a
bank credit facility, asset-based financing, subordinated debt and other
indebtedness. The Company intends to utilize a portion of the net proceeds of
the Offering to repay all of such outstanding indebtedness other than (i) the
New Facility (defined below), (ii) $120,000 owed to Delta Surveys, Inc., (8.5%
interest rate; March 31, 2000 maturity date) which was incurred in connection
with the Company's acquisition of Delta Surveys, Inc. and (iii) $126,000
incurred in connection with the formation of OMNI Geophysical (March 1, 2001
maturity date).
 
  New Facility. On September      , 1997, the Company entered into a $10.0
million term loan (the "Distribution Loan") with Hibernia National Bank to
fund the LLC Distribution and the Preferred Unit Repurchase. This loan bears
interest at LIBOR plus 1.0% and will be secured by the cash distributed in the
LLC Distribution. The Company is currently negotiating with several commercial
lenders to provide the Company with a revolving line of credit of a minimum of
$25.0 million (the "New Facility"). Upon completion of the Offering, the
Company intends to repay the Distribution Loan with borrowings under the New
Facility. The Distribution Loan will not be paid out of proceeds of the
Offering. See "Change in Tax Status and Related Distributions" and "Certain
Transactions."
 
  Capital Expenditures. The Company's capital requirements are primarily for
the purchase or fabrication of new seismic drilling equipment and related
support equipment, the purchase of helicopters and fixed-wing aircraft, and
acquisitions. The Company made capital expenditures of approximately $2.5
million to purchase or construct new assets between July 19, 1996 and December
31, 1996, and made approximately $5.4 million of capital expenditures during
the first six months of 1997, including $0.3 million for the acquisition of
Delta Surveys, Inc., $4.7 million for new equipment and $0.4 million for the
expansion of its Carencro facility. As of September 30, 1997, the Company had
made additional capital expenditures of $11.9 million, primarily for the
acquisition of substantially all the assets, American Aviation and OTH, and
expects to spend approximately $7.0 million during the remainder of 1997,
primarily for the fabrication of additional seismic drilling units and the
purchase of two additional helicopters. The Company currently expects to make
capital expenditures of approximately $12.0 million in 1998, including $6.5
million for the purchase of additional helicopters, $4.5 million for
additional seismic drilling equipment and $1.0 million for support vehicles.
In 1998, the Company
 
                                      27
<PAGE>
 
also expects to spend approximately $750,000 in cash as part of the purchase
price for American Helicopter and to make additional capital expenditures
estimated to be $2.0 million to expand the operations of American Helicopter.
 
  Management believes that the net proceeds from the Offering, cash generated
by operations and funds available under the New Facility and its existing
financing arrangements will be sufficient to meet the Company's anticipated
capital expenditures and debt service requirements for the remainder of 1997
and 1998. However, part of the Company's strategy is to acquire companies with
operations related or complementary to the Company's current operations.
Depending on the size of such future acquisitions, if any, the Company may
require additional debt financing, possibly in excess of the limits of the New
Facility, or equity financing.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENT
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 ("SFAS No. 128"), "Earnings Per
Share," which adopts a revised methodology for computing earnings per share
for publicly owned companies. The Company will be required to adopt the new
methodology in the fourth quarter of 1997. Early adoption of SFAS No. 128 is
not permitted.

                                   BUSINESS
 
GENERAL
 
  The Company is an oilfield service company specializing in providing an
integrated range of onshore seismic drilling, helicopter support and survey
services to geophysical companies operating in logistically difficult and
environmentally sensitive terrain in the United States. The Company's primary
market is the marsh, swamp, shallow water and contiguous dry land areas along
the U.S. Gulf Coast, primarily in Louisiana and Texas. The Company is the
leading provider of seismic drilling services throughout the Transition Zone.
From the mid-1980s to the end of 1996, the majority of 3-D seismic data in the
Transition Zone has been obtained in Louisiana, where approximately 9,000
square miles have been analyzed. The Company performed the seismic drilling
services on approximately 6,300 of these square miles. The Company owns and
operates an extensive fleet of specialized seismic drilling and transportation
equipment for use in the Transition Zone, much of which is fabricated by the
Company. As a result, the Company believes that it is the only company that
currently can both provide an integrated range of seismic drilling, helicopter
support and survey services in all of the varied terrains of the Transition
Zone and simultaneously support operations for multiple, large-scale seismic
projects. The Company has also expanded its seismic drilling operations into
the Rocky Mountain region, where it engages in seismic rock drilling in hard
rock terrain.
 
INDUSTRY OVERVIEW
 
  Seismic data generally consists of computer-generated 3-D images or 2-D
cross sections of subsurface geologic formations and is used in the
exploration for new hydrocarbon reserves and as a tool for enhancing
production from existing reservoirs. Seismic data is acquired by recording
subsurface seismic waves produced by an energy source, usually dynamite, at
various source points at a project site. Historically, 2-D surveys were the
primary technique used to acquire seismic data. However, advances in computer
technology in the last five to ten years have made 3-D seismic data, which
provides a more comprehensive geophysical image, a practical and capable oil
and gas exploration and development tool. 3-D seismic data has proven to be
more accurate and effective than 2-D data at identifying potential
hydrocarbon-bearing geological formations. The use of 3-D seismic data to
identify locations to drill both exploration and development wells has
improved the economics of finding and producing oil and gas reserves, which in
turn has created increased demand for 3-D seismic surveys and seismic support
services.
 
  Oil and gas companies generally contract with independent geophysical
companies to acquire seismic data. Once an area is chosen for seismic
analysis, permits and landowner consents are obtained, either by the
geophysical company or special permitting agents, and the geophysical company
determines the layout of the source and receiving points must be determined by
the geophysical company. For 2-D data, the typical configuration of source and
receiving points is a straight line with a source point and small groups of
geophones, or geophone stations, placed evenly every few hundred feet along
the line. For 3-D data, the configuration is generally a grid of perpendicular
lines spaced a few hundred to a few thousand feet apart, with geophone
stations spaced evenly every few hundred feet along one set of parallel lines,
and source points spaced evenly every few hundred feet along the perpendicular
lines. This configuration is designed by a geophysical company to provide the
best imaging of the targeted geological structures while taking into account
surface obstructions such as water wells and oil and gas wells, pipelines and
areas where landowner consents cannot be obtained. The source points and
geophone locations are then marked by a survey team, and the source points are
drilled and loaded with dynamite.
 
  After the source points have been drilled and loaded and the network of
geophones and field recording boxes deployed over a portion of the project
area, the dynamite is detonated at a source point. Seismic waves generated by
the blast move through the geological formations under the project area and
are reflected by various subsurface strata back to the surface where they are
detected by geophones. The signals from the geophones are collected and
digitized by recording boxes and transmitted to a central recording system. In
the case of 2-D data, the geophones and recording devices from one end of the
line are then shuttled, or "rolled forward," to the
 
                                      29
<PAGE>
 
other end of the line and the process is repeated. In the case of 3-D data,
numerous source points, typically located between the first two lines of a set
of three or four parallel lines of geophone stations are activated in
sequence. The geophone stations and recording boxes from the first of those
lines are then rolled forward to form the next line of geophone stations. The
process is repeated, moving a few hundred feet at a time, until the entire
area to be analyzed has been covered. Long-line helicopter support services
are frequently used to shuttle the geophones and recording devices in an
efficient manner with minimal environmental impact.
 
  After the raw seismic data has been acquired, it is sent to a data
processing facility. The processed data can then be manipulated and viewed on
computer work stations by geoscientists to map the subsurface structures to
identify formations where hydrocarbons are likely to have accumulated and to
monitor the movement of hydrocarbons in known reservoirs. Domestically,
seismic drilling, helicopter support and survey services are typically
contracted to companies such as the Company, as geophysical companies have
found it more economical to outsource these services and focus their efforts
and capital on the acquisition and interpretation of seismic data.
 
DESCRIPTION OF OPERATIONS
 
  The Company provides an integrated range of onshore seismic drilling,
helicopter support and survey services to geophysical companies operating in
logistically difficult and environmentally sensitive terrain in the United
States.
 
  Seismic Drilling Services. The Company's primary activity is the drilling
and loading of source points for seismic analysis. Once the various source
points have been plotted by the geophysical company and a survey crew has
marked their locations, drill crews are deployed to drill and load the source
points. In the Transition Zone, the Company uses water pressure rotary drills
mounted on various types of vehicles to drill the source holes. The type of
vehicle used is determined by the nature, accessibility and environmental
sensitivity of the terrain surrounding the source point. Transition Zone
source holes are generally drilled to depths of 40-180 feet depending on the
nature of the terrain and the needs of the geophysical company, using ten-foot
sections of drill pipe which are carried with the drilling unit. The Company's
vehicles are manned with a driver and one or two helpers. The driver is
responsible for maneuvering the vehicle into position and operating the
drilling unit, while the helper sets and guides the drill into position,
attaches the drilling unit's water source, if drilling in dry areas, and loads
the drill pipe sections used in the drilling process.
 
  In seismic rock drilling, the Company uses compressed air rotary/hammer
drills to drill holes that are typically shallower than Transition Zone holes.
Rock drills are manned by a two- or three-man crew and are transported to and
from locations by hand, surface vehicle or helicopter.
 
  Once the hole has been drilled to the desired depth, it is loaded with
dynamite, which is carried onboard the Company's vehicles in special
containers. The explosive charge is set at the bottom of the drill hole and
then tested to ensure that the connection has remained intact. Once the charge
has been tested, the hole is plugged in accordance with local, state and
federal regulations and marked so that it can be identified for detonation by
the geophysical company at a later date. This process is repeated throughout
the survey area until all source points have been drilled and loaded.
 
  Helicopter Support Services. Through its aviation division, created upon the
acquisition of American Aviation, the Company provides helicopter support
services to geophysical companies in the Transition Zone and elsewhere. The
Company uses long-line helicopters to shuttle geophones and recorders used to
collect seismic data between receiving points. Once seismic data has been
acquired from a portion of the project site, the geophones and recorders must
be moved into position to collect data from the next area to be analyzed. By
using helicopters, the Company is able to reduce delays in completing stages
of a seismic project by transporting the geophones and recording boxes to
their next receiving point in the surveyed area in an efficient manner with
minimal environmental impact.
 
                                      30
<PAGE>
 
  Helicopters are also used to transport heli-portable drilling units into
remote or otherwise inaccessible terrain in an efficient and environmentally
sensitive manner. The Company expects delivery of two heavy-lift helicopters
by year end, which it anticipates will be used to transport rock drilling
units in the Rocky Mountain region.
 
  The Company operates 16 helicopters, 10 of which are owned and six of which
are leased by the Company, with pilots who have an average of 18 years of
flight experience. The Company also owns four airplanes (including one float-
plane) which currently are used to support its operations and to provide
limited charter services. The Company performs all routine maintenance and
repairs on its aircraft at its facilities at the Lafayette Airport.
 
  Survey Services. In March and August 1997, respectively, the Company
acquired two survey companies, Delta Surveys, Inc. and Leonard J. Chauvin,
Jr., Incorporated, for an aggregate of $1.2 million in cash and notes, and
currently has 16 survey crews devoted primarily to the seismic survey market
in the Transition Zone. Through these acquisitions, the Company also acquired
personnel with significant experience in land surveying, with a large
percentage of those years having been spent in Transition Zone surveying. The
Company also provides, on a limited basis, non-seismic, civil survey services
in south Louisiana to the oil and gas industry and other industries.
 
  Once all permits and landowner consents for a seismic project have been
obtained and the geophysical company has determined the placement of source
and receiving points, survey crews are sent into the field to plot each source
and receiving point prior to drilling. The Company employs both GPS (global
positioning satellite) equipment, which is more efficient for surveying in
open areas, and conventional survey equipment, which is generally used to
survey wooded areas. The Company has successfully integrated both types of
equipment in order to complete projects throughout the varied terrain of the
Transition Zone and elsewhere. In addition, the Company's survey crews have
access to the Company's extensive fleet of specialized transportation
equipment, which gives the Company a competitive advantage over most other
survey companies which must rent this equipment.
 
  Fabrication and Maintenance. At its Carencro facilities, the Company
performs all routine repairs and maintenance for its Transition Zone
equipment. The Company designs and fabricates aluminum marsh ATVs, a number of
its support boats and pontoon boats, and the drilling units it uses on all its
Transition Zone equipment. The Company does not fabricate highland rigs and
purchases airboats directly from the manufacturer and then modifies the
airboats to install the drilling equipment. The Company has the capability to
fabricate other key equipment, such as swamp ATVs, but currently has limited
available fabrication space. The Company has signed a non-binding letter of
intent to acquire American Helicopter, a company that, among other things,
fabricates rock drilling equipment. Because of its ability to fabricate and
maintain much of its equipment, the Company does not believe that it is
dependent on any one supplier for its drilling equipment or parts.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to:
 
  Participate in Transition Zone Growth. Seismic data acquisition has been
conducted in the Transition Zone since the 1930s. Within the last decade,
however, improvements in oil and gas drilling and production techniques and
the advent of 3-D imaging have resulted in significantly increased seismic
activity throughout the Transition Zone. In 1996, 3-D seismic data was
acquired from approximately 4,900 square miles of the Transition Zone in
Louisiana compared to 1,500 square miles in 1995 and 1,000 square miles in
1994. During the first six months of 1997, 3-D seismic data was acquired from
approximately 4,100 square miles of the Transition Zone in Louisiana.
Management anticipates that demand for seismic data will continue to grow in
the Transition Zone as a result of 3-D seismic acquisition projects on
unexplored prospects, time-lapsed 3-D analysis, which is generally used to
measure the migration of hydrocarbons in a producing reservoir to enhance
production efforts, and reshoots of previously-surveyed areas with more
advanced seismic technology. The Company intends to maintain its dominant
share of the seismic drilling market in the Transition Zone by fully
participating in this growth.
 
                                      31
<PAGE>
 
  Integrate and Expand Services. The Company intends to capitalize on its
existing customer relationships and its reputation as a reliable service
provider in the Transition Zone to expand its newly-acquired helicopter
support and survey businesses. Management believes that the Company is the
only operator in the Transition Zone that can provide seismic drilling,
helicopter support and survey services on an integrated basis. Management
further believes that the Company's unique ability to package these services
to meet its customers' needs, together with the economies of scale provided by
the size and integrated nature of its operations, will allow the Company to
attract additional projects in the Transition Zone and elsewhere.
 
  Expand Operations in the Rocky Mountain Region. As a result of its recent
acquisition of substantially all of the assets of OTH, the Company has
expanded from its base in the Transition Zone into the seismic rock drilling
market in the Rocky Mountain region. The Company has also entered into a non-
binding letter of intent to acquire American Helicopter and has separately
contracted for delivery of two heavy-lift helicopters by year end, which will
allow the Company to provide integrated heli-portable seismic drilling
services. Management expects the demand for seismic data in the Rocky Mountain
region to grow over the next five years and believes that many of its current
Transition Zone customers will participate in this growth.
 
  Expand Internationally. Management believes that the Company will be well
positioned to expand internationally based on the comprehensive services it
provides in the Transition Zone, its experience operating in difficult
terrains and its recently acquired heli-portable and seismic rock drilling
expertise. Many of the Company's customers who operate in the Transition Zone
also have extensive international operations, but currently perform their own
seismic drilling and related services internationally. The Company believes
that these customers would outsource these services as they have done
domestically if there were reliable and cost-effective third party service
providers operating internationally. Mexico, Venezuela, Indonesia, Tunisia,
the Caspian Sea, South China and West Africa each have transition zones
similar to the U.S. Gulf Coast region where seismic exploration is in various
stages of development. Management believes that the Company's strong industry
reputation and established relationships with its customers will facilitate
the Company's entrance into and development in international markets.
 
  Acquire Related Businesses. Management intends to evaluate opportunities as
they arise to acquire companies that have related or complementary products or
services to those currently provided by the Company. The Company seeks
acquisitions which would, among other things, capitalize on the Company's
dominant position in the Transition Zone seismic drilling market, expand its
Rocky Mountain presence or facilitate its anticipated international expansion.
Immediately after the Offering, management believes that the Company's capital
structure will enable it to pursue such opportunities. However, the Company
does not intend to enter the seismic data acquisition market at any time.
 
FACILITIES AND EQUIPMENT
 
  Facilities. The Company's corporate headquarters, fabrication facility and
primary maintenance facility are located in Carencro, Louisiana, near
Lafayette, Louisiana in facilities leased from OGC. The Company's current
facilities include two buildings that provide approximately 2,500 square feet
of office space and 19,000 square feet of covered maintenance, fabrication and
warehouse space. In connection with the OGC Acquisition, the Company also
acquired a five-year option from OGC to purchase this facility for $500,000.
 
  The Company is constructing two new buildings on approximately 34 acres of
land owned by the Company adjacent to its facilities in Carencro, Louisiana.
Completion is expected by the end of 1997. When completed, the new buildings
will provide approximately 20,000 square feet of additional office space and
32,000 square feet of additional covered maintenance and fabrication space.
With the expansion of its main facility, the Company will be able to expand
operations to include on-site storage and maintenance of its helicopter
assets, which are currently conducted at the Lafayette Airport.
 
  The Company also leases an operations base in Victoria, Texas which is used
to store parts and equipment for use in Texas and a base in Big Piney,
Wyoming, to support the rock drilling assets recently acquired from OTH.
 
                                      32

  Transition Zone Transportation and Drilling Equipment. Because of the varied
terrain throughout the Transition Zone and the prevalence of environmentally
sensitive areas, the Company employs a wide variety of drilling vehicles (see
inside front and back cover pages for photographs of selected equipment).
Management believes that it is the only company currently operating in the
Transition Zone that owns and operates all of the following types of
equipment:

  Because of its extensive fleet of Transition Zone transportation and seismic
drilling equipment, much of which is fabricated by the Company, the Company
believes that it is the only company that currently can both provide an
integrated range of seismic drilling, helicopter support and survey services
in all of the varied terrains of the Transition Zone and simultaneously
support operations for multiple, large-scale seismic projects.
 
  Highland Drilling Units and Water Buggies. The Company owns and operates 14
highland drilling units for seismic drilling in dry land areas. These units
generally consist of a tractor-like vehicle with a drilling unit mounted on
the rear of the vehicle. A highland drilling unit can be driven over land from
point to point and is accompanied by a unit referred to as a "water buggy"
that carries water required for seismic drilling. This type of vehicle is used
around the world for this type of terrain.
 
  Marsh ATVs. The environmentally sensitive wetlands along the U.S. Gulf Coast
containing water grasses on dry land and in shallow water and areas mixed with
open water are referred to as marsh areas. When there is a minimum amount of
water in these areas, marsh ATVs, which are amphibious vehicles supported by
pontoons that are surrounded by tracks, are used to provide seismic drilling
services. The pontoons enable the marsh ATV to float while the tracks propel
the vehicle through the water and over dry marsh areas. Each marsh ATV is
equipped with a drilling unit and a small backhoe for digging a small hole to
collect water necessary for drilling.
 
  Some marsh areas have sufficient surrounding water to support drilling
without an external water source, but often water must be pumped into the area
from a remote water source or a portable supply must be carried by the marsh
ATV. Recently the Company has experimented with several innovative methods of
obtaining a water supply in marsh areas. On some occasions the Company deploys
a vehicle to the source point a few days prior to drilling to dig holes near
the drill sites, which may collect water naturally, either through seepage or
rainfall.
 
  The Company owns and operates 20 marsh ATVs, of which eight are made of
stainless steel and 12 are made of aluminum. The aluminum ATVs are lighter
than steel vehicles and are specifically designed for the environmentally
sensitive areas typically found in marsh terrain. Often landowner consents
will require the use of aluminum ATVs in an effort to reduce the environmental
impact of seismic drilling. The aluminum marsh ATV is the most widely accepted
marsh vehicle for drilling operations in all Louisiana state and federal
refuges. The Company fabricates its own aluminum marsh ATVs at its facilities
in Carencro, Louisiana, and currently owns and operates a majority of the
aluminum marsh ATVs used in seismic drilling in the Transition Zone.
 
  Airboat Drilling Units. The Company owns and operates 28 airboat drilling
units, which represent a majority of the airboat drilling units operating in
the Transition Zone. An airboat drilling unit consists of a
 
                                      33
<PAGE>
 
drilling unit fabricated and installed by the Company on a large, three-engine
airboat. Because of their better mobility, airboat drilling units are used in
shallow waters and all marsh areas where sufficient water is present.
 
  Swamp ATVs and Pullboats. Wooded lowland areas typically covered with water
are referred to as the "swamp areas" of the Transition Zone. The Company's
swamp ATVs are used to provide drilling services in these areas. Swamp ATVs
are smaller, narrower versions of the marsh ATVs. The smaller unit is needed
in swamp areas due to the dense vegetation typical in the terrain. Because of
its smaller size, the swamp ATV uses a skid-mounted drilling unit installed in
a pullboat, a non-motorized craft towed behind the swamp ATV. The Company owns
and operates 25 swamp ATVs and 19 pullboats. Swamp ATVs are also used in
connection with survey operations in swamp areas.
 
  Pontoon Boats. The Company owns and operates 11 pontoon boats that are used
in inland bays and lakes and shallow coastal waters. Each pontoon boat uses a
skid-mounted drilling unit installed on board.
 
  Jack-Up Rigs. When a seismic survey requires source points to be drilled in
inland bays or lakes or in coastal waters, the Company leases a jack-up rig
and mounts one of the Company's skid-mounted drilling units on the jack-up rig
to perform the seismic drilling services. Any seismic activity in water deeper
than approximately 20 feet is generally conducted by using offshore seismic
techniques which do not include the drilling and loading of source points.
 
  Skid-Mounted Drilling Units. A skid-mounted drilling unit is a drilling unit
mounted on I-beam supports, which allows the drilling unit to be moved easily
between pull boats, pontoon boats, jack-up rigs and other Company operated
equipment based on customer needs. The Company manufactures its skid-mounted
drilling units at its plant in Carencro and owns 32 of these units.
 
  Miscellaneous. The Company owns and operates 65 single engine airboats and
23 outboard powered boats, which it uses to ferry personnel and supplies to
locations throughout the Transition Zone. The Company also maintains a fleet
of six tractor-trailer trucks and numerous other trucks, trailers and vehicles
to move its equipment and personnel to projects throughout the Transition
Zone.
 
  Heli-portable and Seismic Rock Drilling Equipment. Through its acquisition
of OTH in August 1997, the Company entered the heli-portable seismic rock
drilling market. The acquisition of OTH and American Helicopter, if
consummated, will provide the Company with 40 heli-portable and man-portable
drilling units and 12 highland drilling units, the ability to manufacture its
own heli-portable and man-portable seismic rock drilling units and an
experienced workforce in this market. American Helicopter also exports and
services heli-portable and man-portable drilling units.
 
  Aviation Equipment. The following table sets forth the type and number of
aircraft that are operated by the Company's aviation division:

    has agreed to purchase two additional Bell 407 helicopters configured for
    the heavy lifting required in heli-portable drilling at an aggregate cost
    of approximately $3 million. Delivery is expected in late 1997.
 
MATERIALS
 
  The principal materials used by the Company in its operations, which include
drills, heli-portable and man-portable drills, drill casings, drill bits,
engines, gasoline and diesel fuel, dynamite, aluminum and steel plate, welding
gasses, aviation fuel, trucks and other vehicles, are currently in adequate
supply from many sources. The Company does not depend upon any single supplier
or source for such materials.
 
SAFETY AND QUALITY ASSURANCE
 
  Management is concerned with the safety and health of the Company's
employees and maintains a stringent safety assurance program to reduce the
possibility of costly accidents. The Company's health, safety and
environmental "HSE" department establishes guidelines to ensure compliance
with all applicable state and federal safety regulations and provides training
and safety education through orientations for new employees, which includes
first aid and CPR training. The Company's Vice President--Health, Safety,
Environment & Training reports directly to the Company's President and
supervises ten HSE field advisors. The Company believes that its safety
program and commitment to quality are vital to attracting and retaining
customers and employees.
 
  Each drilling crew is supervised at the project site by a field supervisor
and an assistant supervisor, together with a powderman who is in charge of all
explosives. For large projects or when required by a customer, a separate
advisor from the Company's HSE department is also located at the project site.
Management is provided with daily updates for each project and believes that
its daily review of field performance together with the on-site presence of
supervisory personnel helps ensure high quality performance for all of its
projects.
 
  All Company pilots are trained to FAA FAR 135 (non-scheduled commercial
passenger) standards and must satisfy annual FAA check-rides. Certified
maintenance personnel are deployed to each project site at which aircraft are
used.
 
CUSTOMERS; MARKETING; CONTRACTING
 
  Customers. The Company's customers are primarily geophysical companies with
operations in the Transition Zone as well as oil and gas companies, which in
many cases participate in determining which drilling, survey or aviation
company will be used on their respective seismic projects.
 
  A large portion of the Company's revenue has historically been generated by
a few customers. For example, the Company's largest customers (those which
individually accounted for more than 10% of revenue in a given year, listed
alphabetically) collectively accounted for 88% (Digicon/GFS, Eagle
Geophysical, Grant Geophysical and Seismic Exchange), 88% (Digicon/GFS, Eagle
Geophysical, Grant Geophysical and Western Geophysical) and 70% (Eagle
Geophysical, Grant Geophysical, Universal Seismic and Western Geophysical), of
revenue for fiscal 1994, 1995 and 1996, respectively. In addition, as of
August 31, 1997, 70% of the Company's backlog was attributable to two
customers.
 
  Marketing. The Company's services traditionally have been marketed by the
Company's principal executive officers, in particular, Messrs. Jeansonne,
Thomas, Woodard and Morris. After the Offering, the Company intends to
maintain this marketing approach in order to preserve long-term relationships
established by the Company's executive officers. As the Company's geographical
and service capabilities expand, the Company intends to continue implementing
its marketing efforts in the Transition Zone from its principal offices in
Carencro, Louisiana and intends to establish a sales office for the Rocky
Mountain region in Denver, Colorado.
 
                                      35
<PAGE>
 
  Contracting--Seismic Drilling. The Company generally contracts for seismic
drilling services with its customers on a fixed-price basis, either on a per
hole or per foot basis. These contracts are often awarded on a competitive bid
basis. The Company prices its contracts based on detailed project
specifications provided by the customer, including the number, location and
depth of source holes and the project's completion schedule. As a result, the
Company is generally able to make a relatively accurate determination prior to
pricing a contract of the type and amount of equipment required to complete
the contract on schedule.
 
  Because of fixed-priced contracting, the Company generally bears the risk of
delays that are beyond its control, such as those caused by adverse weather.
The Company often bills the customer standby charges if the Company's
operations are delayed due to delays in permitting or surveying or for other
reasons within the geophysical company's control.
 
  Contracting--Helicopter Support Services. The Company's aircraft are
chartered on an hourly rate basis, with a guaranteed minimum number of hours
per day. The Company primarily provides aviation services in connection with
projects for which the Company also provides seismic drilling services, and
also charters its aircraft to customers for use with other seismic projects.
 
  Contracting--Survey Services. The Company contracts for seismic services
with its customers on a day rate basis. Contracts are often awarded to the
Company only after competitive bidding. In each case, the price is determined
by the Company after it has taken into account such factors as the number of
surveyors and other employees, the type of terrain and transportation
equipment, and the precision required for the project based on detailed
project specifications provided by the customer.
 
COMPETITION
 
  Seismic Drilling Services. The principal competitive factors for seismic
drilling services are price and the ability to meet customer schedules,
although other factors, including safety, capability, reputation and
environmental sensitivity are also considered by customers. The Company has
numerous competitors in the Transition Zone and in particular in the highland
areas in which its operates. The Company believes there are numerous
competitors offering rock and heli-portable drilling in the Rocky Mountain
region and internationally.
 
  Management believes that no other company operating in the Transition Zone
owns a fleet of Transition Zone seismic drilling equipment as extensive or as
large as that operated by the Company. The Company's extensive and diverse
equipment base allows it to provide drilling services to its customers
throughout the Transition Zone with the most efficient and environmentally
appropriate equipment. Management believes that the Company has a significant
competitive advantage in the Transition Zone because of the size and diversity
of its equipment base, the Company's financial resources and economies of
scale.
 
  Helicopter Support Services. The Company has numerous competitors that
provide helicopter support services to geophysical companies operating in the
Transition Zone; however, none of these competitors currently provides long-
line helicopter services with a comparable number of aircraft. In addition,
the Company believes that it is the only company offering both seismic
drilling and long-line support services in the Transition Zone. The Company
believes that there are numerous companies offering helicopter services in
rock drilling and other mountain areas, as well as internationally. All of
these companies have greater experience in these areas and several operate
more aircraft than the Company in these areas.
 
  Survey Services. The Company's competitors include a number of established
companies with a comparable number of crews to the Company and numerous
smaller companies.
 
SEASONALITY AND WEATHER RISKS
 
  The Company's operations are subject to seasonal variations in weather
conditions and daylight hours. Since the Company's activities take place
outdoors, the average number of hours worked per day, and therefore the number
of holes drilled or surveyed per day, generally is less in winter months than
in summer months, due to
 
                                      36
<PAGE>
 
an increase in rainy, foggy and cold conditions and a decrease in daylight
hours. Furthermore, demand for seismic data acquisition activity by oil and
gas companies in the first quarter is generally lower than at other times of
the year. As a result, the Company's revenue and gross profit during the first
quarter of each year are typically low as compared to the other quarters.
Operations may also be affected by the rainy weather, lightning, hurricanes
and other storms prevalent along the Gulf Coast throughout the year and by
seasonal climatic conditions in the Rocky Mountain area. In addition,
prolonged periods of dry weather result in slower drill rates in marsh and
swamp areas as water in the quantities needed to drill is more difficult to
obtain and equipment movement is impeded. Adverse weather conditions and dry
weather could increase maintenance costs for the Company's equipment and
decrease the number of vehicles available for operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
General--Seasonality and Weather" and "Risk Factors--Seasonality and Weather
Risks."
 
BACKLOG
 
  The Company's backlog represents those projects for which a customer has
hired the Company and has scheduled a start date for the project. Projects
currently included in the Company's backlog are subject to termination without
penalty at the option of the customer, which could substantially reduce the
amount of backlog currently reported. Historically, the Company has not
experienced a large volume of project terminations, and terminations from its
backlog have typically been replaced by unscheduled projects. See "Risk
Factors--Backlog."
 
  As of August 31, 1997, the Company's backlog was approximately $61.2 million
compared to $29.6 million at August 31, 1996. The Company expects that $45.5
million of its backlog at August 31, 1997 will be completed within the next
twelve months. The backlog at August 31, 1997 and August 31, 1996 includes
seismic drilling projects in the Transition Zone, and the backlog at August
31, 1997 also includes survey projects. At such dates there was no backlog
attributable to the Company's seismic drilling projects in the Rocky Mountain
region. The Company's aviation division historically has not measured backlog
due to the nature of the business.
 
GOVERNMENTAL REGULATION
 
  The Company's operations and properties are subject to and affected by
various types of governmental regulation, including laws and regulations
governing the entry into and restoration of wetlands, the handling of
explosives, the operation of commercial aircraft and numerous other federal,
state and local laws and regulations. To date the Company's cost of complying
with such laws and regulations has not been material, but because such laws
and regulations are changed frequently, it is not possible for the Company to
accurately predict the cost or impact of such laws and regulations on its
future operations.
 
  Furthermore, the Company depends on the demand for its services by the oil
and gas industry and is affected by changing taxes, price controls and other
laws and regulations relating to the oil and gas industry generally. The
adoption of laws and regulations curtailing exploration and development
drilling for oil and gas in the Company's areas of operations for economic,
environmental or other policy reasons would adversely affect the Company's
operations by limiting demand for its services. The Company cannot determine
to what extent future operations and earnings of the Company may be affected
by new legislation, new regulations or changes in existing regulations. See
"Risk Factors--Regulatory and Environmental Matters."
 
  Aviation. As a commercial operator of small aircraft, the Company is subject
to regulations pursuant to the Federal Aviation Act and other statutes. The
FAA regulates the flight operations of the Company, and in this respect,
exercises jurisdiction over personnel, aircraft, ground facilities and other
aspects of the Company's operations.
 
  The Company carries persons and property in its aircraft pursuant to
authority granted by the FAA. Under the Federal Aviation Act, it is unlawful
to operate certain aircraft for hire within the United States unless such
aircraft are registered with the FAA and the operator of such aircraft has
been issued an operating certificate by
 
                                      37
<PAGE>
 
the FAA. The Company has all FAA certificates required to conduct its
helicopter and aviation operations, and all of its aircraft are registered
with the FAA.
 
  As a general rule, aircraft may be registered under the Federal Aviation Act
only if the aircraft is owned or controlled by one or more citizens of the
United States, and an operating certificate may be granted only to a citizen
of the United States. For purposes of these requirements, a corporation is
deemed to be a citizen of the United States only if, among other things, at
least 75% of the voting interest therein is owned or controlled by United
States citizens. In the event that persons other than United States citizens
should come to own or control more than 25% of the voting interest in the
Company, the Company has been advised that its aircraft may be subject to
deregistration under the Federal Aviation Act and loss of the privilege of
operating within the United States. The Company's Articles of Incorporation
include provisions that are designed to ensure compliance with this
requirement. See "Risk Factors--Limitations on Foreign Ownership of Company
Stock" and "Description of Capital Stock--Limitations on Foreign Ownership of
Company Stock."
 
  Explosives. Because the Company loads the holes that it drills with
dynamite, the Company is subject to various local, state and federal laws and
regulations concerning the handling and storage of explosives and is
specifically regulated by the ATF. The Company must take daily inventories of
the dynamite and blasting caps that it keeps for its seismic drilling and is
subject to random checks by state and federal officials. The Company is
licensed by the Louisiana State Police as an explosives handler. Any loss or
suspension of this license would result in a material adverse effect on the
Company's results of operations and financial condition. The Company believes
that it is in compliance with all material laws and regulations with respect
to its handling and storage of explosives.
 
  Environmental. The Company's operations and properties are subject to a wide
variety of increasingly complex and stringent federal, state and local
environmental laws and regulations, including those governing discharges into
the air and water, the handling and disposal of solid and hazardous wastes,
the remediation of soil and groundwater contaminated by hazardous substances
and the health and safety of employees. In addition, certain areas where the
Company operates are federally-protected or state-protected wetlands or
refuges where environmental regulation is particularly strict. These laws may
provide for "strict liability" for damages to natural resources and threats to
public health and safety, rendering a party liable for the environmental
damage without regard to negligence or fault on the part of such party.
Sanctions for noncompliance may include revocation of permits, corrective
action orders, administrative or civil penalties and criminal prosecution.
Certain environmental laws provide for strict, joint and several liability for
remediation of spills and other releases of hazardous substances, as well as
damage to natural resources. In addition, the Company may be subject to claims
alleging personal injury or property damage as a result of alleged exposure to
hazardous substances. Such laws and regulations may also expose the Company to
liability for the conduct of, or conditions caused by, others, or for acts of
the Company that were in compliance with all applicable laws at the time such
acts were performed.
 
  The Comprehensive Environmental Response, Compensation, and Liability Act of
1980, as amended, and similar laws provide for responses to and liability for
releases of hazardous substances into the environment. Additionally, the Clean
Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, the
Safe Drinking Water Act, the Emergency Planning and Community Right to Know
Act, each as amended, and similar state or local counterparts to these federal
laws, regulate air emissions, water discharges, hazardous substances and
wastes, and require public disclosure related to the use of various hazardous
substances. Compliance with such environmental laws and regulations may
require the acquisition of permits or other authorizations for certain
activities and compliance with various standards or procedural requirements.
The Company believes that its facilities are in substantial compliance with
current regulatory standards.
 
  Worker Safety. The Company's operations are governed by laws and regulations
relating to workplace safety and worker health, primarily the Occupational
Safety and Health Act and regulations promulgated thereunder. In addition,
various other governmental and quasi-governmental agencies require the Company
to obtain certain permits, licenses and certificates with respect to its
operations. The kind of permits, licenses and certificates
 
                                      38
<PAGE>
 
required in the Company's operations depend upon a number of factors. The
Company believes that it has all material permits, licenses and certificates
necessary to the conduct of its existing business.
 
INSURANCE
 
  The Company's operations are subject to the inherent risks of inland marine
activity, aviation services, heavy equipment operations and the transporting
and handling of explosives, including accidents resulting in personal injury,
the loss of life or property, environmental mishaps, mechanical failures and
collisions. The Company maintains insurance coverage against certain of these
risks, which management considers to be customary in the industry. The Company
also maintains insurance coverage against property damage caused by fire,
flood, explosion and similar catastrophic events that may result in physical
damage or destruction to the Company's equipment or facilities. All policies
are subject to deductibles and other coverage limitations. The Company
believes its insurance coverage is adequate. The Company has not experienced a
loss in excess of its policy limits; however, there can be no assurance that
the Company will be able to maintain adequate insurance at rates which
management considers commercially reasonable, nor can there be any assurance
such coverage will be adequate to cover all claims that may arise. See "Risk
Factors--Operating Risks."
 
EMPLOYEES
 
  As of August 31, 1997, the Company had approximately 600 employees,
including approximately 560 operating personnel and approximately 40
corporate, administrative and management personnel. These employees are not
unionized or employed pursuant to any collective bargaining agreement or any
similar agreement. The Company believes its relationship with its employees is
strong.
 
LEGAL PROCEEDINGS
 
  The Company is involved in various legal and other proceedings which are
incidental to the conduct of its business. The Company believes that none of
these proceedings, if adversely determined, would have a material adverse
effect on the Company's financial condition, results of operations or cash
flows.

STOCK INCENTIVE PLAN
 
  In September 1997, the Company adopted and its shareholders approved the
Stock Incentive Plan (the "Incentive Plan") to provide long-term incentives to
its key employees and officers and directors who are employees of the Company
(the "Eligible Employees") and non-employee directors. Under the Incentive
Plan, which is administered by the Compensation Committee of the Board of
Directors, the Company may grant incentive stock options, non-qualified stock
options, restricted stock, other stock-based awards or any combination thereof
(the "Incentives") to Eligible Employees. The Compensation Committee will
establish the exercise price of any stock options granted to Eligible
Employees under the Incentive Plan, but the exercise price may not be less
than the fair market value of the Common Stock on the date of grant. The
option exercise price may be paid in cash, in Common Stock, in a combination
of cash and Common Stock, or through a broker-assisted exercise arrangement
approved by the Compensation Committee.
 
  A total of 1,500,000 shares of Common Stock are available for issuance under
the Incentive Plan. Incentives with respect to no more than 400,000 shares of
Common Stock may be granted to any single Eligible Employee in one calendar
year. Proportionate adjustments will be made to the number of shares subject
to the Incentive Plan, including the shares subject to outstanding Incentives,
in the event of any recapitalization, stock dividend, stock split, combination
of shares or other change in the Common Stock. In the event of such
adjustments, the purchase price of any outstanding option, the performance
objectives of any Incentive, and the shares of Common Stock issuable pursuant
to any Incentive will be adjusted as and to the extent appropriate, in the
reasonable discretion of the Compensation Committee, to provide participants
with the same relative rights before and after such adjustment.
 
  Restricted stock consists of shares of Common Stock that are transferred to
a participant for past services but subject to restrictions regarding their
sale, pledge or other transfer by the participant for a specified period (the
"Restricted Period"). The Compensation Committee has the power to determine
the number of shares to be transferred to a participant as restricted stock.
All shares of restricted stock will be subject to such restrictions as the
Compensation Committee may designate in the incentive agreement with the
participant, including, among other things, that the shares of Common Stock
are required to be forfeited or resold to the Company in the event of
termination of employment or in the event specified performance goals or
targets are not met. A Restricted Period of at least three years is required,
except that if vesting is subject to the attainment of performance goals, a
minimum Restricted Period of one year is required. Subject to the restrictions
provided in the incentive agreement, each participant receiving restricted
stock will have the rights of a shareholder with respect thereto,
 
                                      43
<PAGE>
 
including voting rights and rights to receive dividends. To the extent that
restricted stock is intended to vest based upon the achievement of pre-
established performance goals rather than solely upon continued employment
over a period of time, the performance goals pursuant to which the restricted
stock shall vest shall be any or a combination of the following performance
measures: earnings per share, return on assets, an economic value added
measure, shareholder return, earnings, stock price, return on equity, return
on total capital, safety performance, reduction of expenses or increase in
cash flow of the Company, a division of the Company or a subsidiary. For any
performance period, such performance objectives may be measured on an absolute
basis or relative to a group of peer companies selected by the Compensation
Committee, relative to internal goals or relative to levels attained in prior
years.
 
  The Compensation Committee is authorized to grant to Eligible Employees
another stock-based award ("Other Stock-Based Award"), which consists of an
award, the value of which is based in whole or in part on the value of shares
of Common Stock, other than a stock option or a share of restricted stock.
Other Stock-Based Awards may be awards of shares of Common Stock or may be
denominated or payable in, valued in whole or in part by reference to, or
otherwise based on or related to, shares of Common Stock. The Compensation
Committee shall determine the terms and conditions of any such Other Stock-
Based Award and may provide that such awards would be payable in whole or in
part in cash. Except in the case of an Other Stock-Based Award granted in
assumption of or in substitution for an outstanding award of a company
acquired by the Company or with which the Company combines, the price at which
securities may be purchased pursuant to any Other Stock-Based Award or the
provision, if any, of any such award that is analogous to the purchase or
exercise price, shall not be less than 100% of the fair market value of the
securities to which such award relates on the date of grant. In the sole and
complete discretion of the Compensation Committee, an Other Stock-Based Award
may provide the holder thereof with dividends or dividend equivalents, payable
in cash or shares of Common Stock on a current or deferred basis. Other Stock-
Based Awards intended to qualify as "performance-based compensation" shall be
paid based upon the achievement of pre-established performance goals. The
performance goals pursuant to which Other Stock-Based Awards shall be earned
shall be any or a combination of the following performance measures: earnings
per share, return on assets, an economic value added measure, shareholder
return, earnings, stock price, return on equity, return on total capital,
safety performance, reduction of expenses or increase in cash flow of the
Company, a division of the Company or a subsidiary. For any performance
period, such performance goals may be measured on an absolute basis or
relative to a group of peer companies selected by the Compensation Committee,
relative to internal goals or relative to levels attained in prior years. The
grant of an Other Stock-Based Award to a participant shall not create any
rights in such participant as a shareholder of the Company, until the issuance
of shares of Common Stock with respect to such Other Stock-Based Award.
 
  To assist a participant in acquiring shares of Common Stock pursuant to an
Incentive granted under the Incentive Plan, the Compensation Committee may
authorize the extension of a loan by the Company to the participant to cover
the aggregate purchase price of such shares and the maximum tax liability that
arises in connection with the Incentive. The terms of any such loan will be
determined by the Compensation Committee.
 
  The Compensation Committee may also grant a tax benefit right to a
participant under the Incentive Plan. A tax benefit right entitles the holder
thereof to receive from the Company an amount in cash not to exceed the
product of (i) any ordinary income that the participant may realize as the
result of the exercise of an option granted under the Incentive Plan or the
grant or vesting of restricted stock or Other Stock-Based Awards under the
Incentive Plan, including any income realized as a result of the receipt of
such tax benefit right, and (ii) the then applicable highest stated federal
and state tax rate for individuals. The terms of any such tax benefit right
will be determined by the Compensation Committee.
 
  Upon consummation of the Offering, each director who is not an employee of
the Company (an "Outside Director") will be granted under the Incentive Plan a
non-qualified stock option to purchase 10,000 shares of Common Stock at an
exercise price equal to the initial per share public offering price. Each
person who subsequently becomes an Outside Director will be granted under the
Incentive Plan, effective as of the date that he or she becomes an Outside
Director, a non-qualified stock option to purchase 10,000 shares of Common
Stock
 
                                      44
<PAGE>
 
at an exercise price equal to the fair market value of a share of Common Stock
as of that date. In 1998 and in each subsequent year during which the
Incentive Plan is in effect and a sufficient number of shares of Common Stock
are available thereunder, each person who is an Outside Director as of the day
following the annual meeting of Company stockholders in such year will be
granted under the Incentive Plan a non-qualified stock option to purchase
5,000 shares of Common Stock at an exercise price equal to the fair market
value of a share of Common Stock as of such date. Each non-qualified stock
option granted to an Outside Director shall become fully exercisable on the
first anniversary of its grant and shall expire on the tenth anniversary of
its grant, unless such Outside Director terminates his position as a Company
director, in which event such Outside Director's then exercisable non-
qualified stock options will expire within three months after his termination
or, if his termination is a result of his death, disability or retirement
after the age of 65, within eighteen months after his termination, but in no
event later than the tenth anniversary of the grant thereof.
 
  All outstanding stock options granted under the Incentive Plan will
automatically become fully exercisable, all restrictions or limitations on any
Incentives will lapse and all performance criteria and other conditions
relating to the payment of Incentives will be deemed to be achieved or waived
by the Company upon (i) approval by the shareholders of the Company of a
reorganization, merger or consolidation of the Company or sale of all or
substantially all of the assets of the Company, unless (x) all or
substantially all of the individuals and entities who were the beneficial
owners of the Company's outstanding Common Stock and voting securities
entitled to vote generally in the election of directors immediately prior to
such transaction have direct or indirect beneficial ownership, respectively,
of more than 50% of the then outstanding shares of common stock and more than
50% of the combined voting power of the then outstanding voting securities
entitled to vote generally in the election of directors of the resulting
corporation; (y) except to the extent that such ownership existed prior to the
transaction, no person (excluding any corporation resulting from the
transaction or any employee benefit plan or related trust of the Company or
the resulting corporation) beneficially owns, directly or indirectly, 30% or
more of the then outstanding shares of common stock of the resulting
corporation or 30% or more of the combined voting power of the then
outstanding voting securities of the resulting corporation; or (z) a majority
of the board of directors of the resulting corporation were members of the
Company's board of directors at the time of the execution of the initial
agreement or of the action of the Board providing for the transaction; (ii)
approval by the shareholders of the Company of a complete liquidation or
dissolution of the Company; (iii) a person or group of persons becoming the
beneficial owner of more than 50% of the Company's Common Stock (subject to
certain exceptions); or (iv) the individuals who as of the adoption of the
Incentive Plan constitute the Board (the "Incumbent Board") or who
subsequently become a member of the Board with the approval of at least a
majority of the directors then comprising the Incumbent Board other than in
connection with an actual or threatened election contest cease to constitute
at least a majority of the Board (each, a "Significant Transaction").
 
  The Compensation Committee also has the authority to take several actions
regarding outstanding Incentives upon the occurrence of a Significant
Transaction, including (i) requiring that all outstanding options remain
exercisable only for a limited time, (ii) making equitable adjustments to
Incentives as the Compensation Committee deems in its discretion necessary to
reflect the Significant Transaction or (iii) providing that an option under
the Incentive Plan shall become an option relating to the number and class of
shares of stock or other securities or property (including cash) to which the
participant would have been entitled in connection with the Significant
Transaction if the participant had been immediately prior to the Significant
Transaction the holder of record of the number of shares of Common Stock then
covered by such options.
 
  When an optionee exercises a non-qualified option, the difference between
the exercise price and any higher fair market value of the Common Stock on the
date of exercise will be ordinary income to the optionee (subject to
withholding) and will generally be allowed as a deduction at that time for
federal income tax purposes to the Company.
 
  Any gain or loss recognized by an optionee on disposition of the Common
Stock acquired upon exercise of a non-qualified option will generally be
capital gain or loss to the optionee. Under recent amendments to the Code, the
maximum capital gains rate for individuals on gain on certain assets, such as
shares of Common Stock,
 
                                      45
<PAGE>
 
which are sold after July 28, 1997 and which are held for more than eighteen
months is reduced to 20%. The optionee's basis in the Common Stock for
determining gain or loss on the disposition will be the fair market value of
the Common Stock determined generally at the time of exercise. The disposition
by an optionee of Common Stock acquired upon exercise of a non-qualified
option will not result in any additional federal income tax consequences to
the Company.
 
  When an optionee exercises an incentive stock option while employed by the
Company or a subsidiary or within three months after termination of employment
by reason of retirement or death (one year for disability), no ordinary income
will be recognized by the optionee at that time, but the excess (if any) of
the fair market value of the Common Stock acquired upon such exercise over the
option price will be an adjustment to taxable income for purposes of the
federal alternative minimum tax applicable to individuals. If the Common Stock
acquired upon exercise of the incentive stock option is not disposed of prior
to the expiration of one year after the date of acquisition and two years
after the date of grant of the option, the excess (if any) of the sale
proceeds over the aggregate option exercise price of such Common Stock will be
long-term capital gain, but the Company will not be entitled to any tax
deduction with respect to such gain. Generally, if the Common Stock is
disposed of prior to the expiration of such periods (a "Disqualifying
Disposition"), the excess of the fair market value of such Common Stock at the
time of exercise over the aggregate option exercise price (but not more than
the gain on the disposition if the disposition is a transaction on which a
loss, if realized, would be recognized) will be ordinary income at the time of
such Disqualifying Disposition (and the Company will generally be entitled to
a federal income tax deduction in a like amount). Any gain realized by the
optionee as the result of a Disqualifying Disposition that exceeds the amount
treated as ordinary income will be capital gain. If an incentive stock option
is exercised more than three months after termination of employment (one year
for disability), the federal income tax consequences are the same as described
above for non-qualified stock options.
 
  If the exercise price of an option is paid by the surrender of previously
owned shares, the basis of the previously owned shares carries over to the
shares received in replacement therefor. If the option is a non-qualified
option, the income recognized on exercise is added to the basis. If the option
is an incentive stock option, the optionee will recognize gain if the shares
surrendered were acquired through the exercise of an incentive stock option
and have not been held for the applicable holding period. This gain will be
added to the basis of the shares received in replacement of the previously
owned shares.
 
  Awards under the Incentive Plan that are granted, accelerated or enhanced
upon the occurrence of a change of control may give rise, in whole or in part,
to excess parachute payments within the meaning of Section 280G of the
Internal Revenue Code of 1986 (the "Code") to the extent that such payments,
when aggregated with other payments subject to Section 280G, exceed the
limitations contained therein. Such excess parachute payments will be
nondeductible to the Company and subject the recipient of the payments to a
20% excise tax.
 
  If permitted by the Compensation Committee, at any time that a participant
is required to pay the Company the amount required to be withheld under
applicable tax laws in connection with the exercise of a stock option, the
participant may elect to have the Company withhold from the shares that the
participant would otherwise receive shares of Common Stock having a value
equal to the amount to be withheld. This election must be made prior to the
date on which the amount of tax to be withheld is determined.
 
  The foregoing discussion summarizes the federal income tax consequences
pertaining to stock options granted under the Incentive Plan based on current
provisions of the Code, which are subject to change. This summary does not
cover any foreign, state or local tax consequences of participation in the
Incentive Plan.

OTHER STOCK OPTIONS
 
  Prior to the adoption of the Incentive Plan, individual grants of options on
Company securities were made in 1997 to four employees of the Company who are
not Named Executive Officers. The grants, as adjusted in connection with the
Share Exchange, cover a total of 118,018 shares of Common Stock at an option
exercise price of $2.28 per share, including an award to Mr. Crays for 54,567
shares of Common Stock at such exercise price. The options granted to the four
employees in 1997 are exercisable in three equal installments on the first,
second and third anniversaries of the date of grant and remain exercisable
until the tenth anniversary of the date of grant, provided the holder is
employed by the Company.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Board of Directors had no Compensation Committee or other committee
performing similar functions in 1996. Max B. Hoyt and Ted W. Hoyt, who were
former officers of the Company, and Messrs. Jeansonne, Thomas and Woodard
participated in deliberations of the Board of Directors during 1996 concerning
executive officer compensation.
 
LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY AND INDEMNIFICATION
 
  As permitted by Louisiana Law, the Company's Articles of Incorporation
contain certain provisions eliminating the personal liability of the directors
and officers to the Company and its shareholders for monetary damages for
breaches of their fiduciary duties as directors or officers, except for (i) a
breach of a director's or officer's duty of loyalty to the Company or to its
shareholders, (ii) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) dividends or stock
repurchases or redemptions that are illegal under Louisiana law and (iv) any
transaction from which he or she receives an improper personal
 
                                      47
<PAGE>
 
benefit. In addition, the Articles of Incorporation provide that if Louisiana
law is amended to authorize the further elimination or limitation of the
liability of a director or officer, then the liability of the directors or
officers shall be eliminated or limited to the fullest extent permitted by
Louisiana law, as amended. These provisions pertain only to breaches of duty
by directors or officers in such capacities and limit liability only for
breaches of fiduciary duties under Louisiana corporate law and not for
violations of other laws such as the federal securities laws.
 
  As a result of the inclusion of such provisions, shareholders may be unable
to recover monetary damages against directors or officers for actions taken by
them that constitute negligence or gross negligence or that are in violation
of their fiduciary duties, although it may be possible to obtain injunctive or
other equitable relief with respect to such actions. If equitable remedies are
found not to be available to shareholders in any particular case, shareholders
may not have any effective remedy against the challenged conduct. These
provisions may have the effect of reducing the likelihood of derivative
litigation against directors or officers that might have benefitted the
Company.
 
  The Company believes that such provisions are necessary to attract and
retain qualified individuals to serve as directors and officers. In addition,
such provisions will allow directors and officers to perform their duties in
good faith without undue concern about personal liability if a court finds
their conduct to have been negligent or grossly negligent. On the other hand,
the potential remedies available to a Company shareholder will be limited, and
it is possible, although unlikely, that directors and officers protected by
these provisions may not demonstrate the same level of diligence or care that
they would otherwise demonstrate.
 
  The Company's By-laws require the Company to indemnify its directors and
officers against certain expenses and costs, judgments, settlements and fines
incurred in the defense of any claim, including any claim brought by or in the
right of the Company, to which they were made parties by reason of being or
having been directors and officers, subject to certain conditions and
limitations.
 
  In addition, each of the Company's directors and executive officers has
entered into an indemnity agreement with the Company, pursuant to which the
Company has agreed under certain circumstances to purchase and maintain
directors' and officers' liability insurance. The agreements also provide that
the Company will indemnify the directors and executive officers against any
costs and expenses, judgments, settlements and fines incurred in connection
with any claim involving a director or executive officer by reason of his
position as a director or executive officer that are in excess of the coverage
provided by such insurance; provided that the director or executive officer
meets certain standards of conduct. A form of indemnity agreement containing
such standards of conduct is included as an exhibit to the Registration
Statement of which this Prospectus forms a part. Under the indemnity
agreements, the Company is not required to purchase and maintain directors'
and officers' liability insurance if it is not reasonably available or, in the
reasonable judgment of the Board of Directors, there is insufficient benefit
to the Company from the insurance.

                             CERTAIN TRANSACTIONS
 
  On July 19, 1996, OMNI Geophysical acquired substantially all of the assets
of OGC, of which Mr. Jeansonne is a director, executive officer and principal
shareholder. The purchase price was approximately $13.3 million, of which $11
million was paid in cash and $2.3 million was paid by the delivery of a
subordinated note. The cash portion was financed through the issuance by OMNI
Geophysical of 4,000 of its 10% participating units to Advantage Capital for
$4.0 million and the proceeds from a $7 million asset-based loan. Since the
OGC Acquisition, Advantage Capital purchased additional common units and 1,000
15% participating preferred units of OMNI Geophysical for an aggregate of $1.1
million. See "Principal Shareholders."
 
  OGC and OMNI Geophysical have made cash dividends and distributions to
provide cash returns to their securityholders as well as to fund federal and
state income tax liabilities. Dividends to OGC shareholders totaled $765,250
during 1995 and $881,200 during the 201-day period ended July 19, 1996.
Distributions to OMNI Geophysical members totaled $18,810 during the 165-day
period ended December 31, 1996 and $320,642 during the six months ended June
30, 1997.
 
  Prior to the Share Exchange, all of the undistributed earnings of OMNI
Geophysical through the date of the Share Exchange will be distributed to the
current members of OMNI Geophysical. At June 30, 1997, OMNI Geophysical's
undistributed earnings totaled approximately $3.7 million. Management
estimates that it will have additional undistributed earnings of approximately
$      million, for an aggregate of $      million, at the time of the Share
Exchange. Prior to the Share Exchange, OMNI Geophysical will also repurchase
all of the outstanding preferred units of OMNI Geophysical for $5.0 million.
 
  Effective July 1, 1997, the Company purchased substantially all of the
assets of American Aviation, a corporation of which Mr. Jeansonne is the
president and chief executive officer and holder of 90% of the outstanding
shares and Mr. Morris is a vice president and holder of 10% of the outstanding
shares. American Aviation was formed on November 1, 1995. In connection with
the transaction, American Aviation received 10,213 common units of OMNI
Geophysical, $0.5 million in cash and a $1 million subordinated note that
bears interest at 8.5% and is payable upon demand by the note holder subject
to certain restrictions included in the Company's primary lending agreements.
This note will be repaid with a portion of the proceeds of the Offering. The
Company also assumed approximately $6.7 million of indebtedness of American
Aviation, including $3.4 million owed to Mr. Jeansonne for working capital
advances. All of the assumed indebtedness was repaid at the time of the
acquisition with borrowings from Hibernia National Bank, which will be repaid
with a portion of the net proceeds of the Offering. Prior to such transaction,
OMNI Geophysical had purchased a Bell 206B-III helicopter from American
Aviation for $526,000.
 
  The Company was formed on September 11, 1997, solely to facilitate the
Offering. Immediately prior to completion of the Offering, the holders of
common units in OMNI Geophysical and the Company will consummate the Share
Exchange, pursuant to which such unitholders will exchange all of their common
units for 12,000,000 shares of Common Stock.
 
  Since the OGC Acquisition, OMNI Geophysical has leased the land and building
in which its headquarters are located under an agreement with OGC that also
contains an option to buy such property. OMNI Geophysical paid $25,000 under
this lease during 1996 and $30,000 in the six months ended June 30, 1997.

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of 45,000,000 shares of
Common Stock, $0.01 par value per share, and 5,000,000 shares of preferred
stock, $0.01 par value per share, issuable in series (the "Preferred Stock").
Upon completion of the Share Exchange immediately prior to the consummation of
the Offering, the Company will have 12,000,000 shares of Common Stock
outstanding, which will be held of record by approximately 15 persons. No
shares of Preferred Stock will be outstanding. Prior to the Offering, there
has been no public market for the Common Stock. Although application has been
made to have the Common Stock listed on the Nasdaq National Market, there can
be no assurance that a market for the Common Stock will develop or, if
developed, will be sustained. See "Risk Factors--No Prior Market; Possible
Volatility of Market Price." The following summary description of the capital
stock of the Company is qualified in its entirety by reference to the
Company's Articles of Incorporation and By-laws, copies of which are filed as
exhibits to the Registration Statement of which this Prospectus forms a part.
 
COMMON STOCK
 
  Holders of Common Stock are entitled to one vote per share in the election
of directors and on all other matters submitted to a vote of shareholders;
shareholders may not cumulate votes for the election of directors. Subject to
any preferences accorded to the holders of the Preferred Stock, if and when
issued by the Board of Directors, holders of Common Stock are entitled to
dividends at such times and in such amounts as the Board of Directors may
determine. The Company currently does not intend to declare or pay dividends
for the foreseeable future. In addition, several of the Company's credit
arrangements restrict distributions to the Company's shareholders. See "Risk
Factors--Dividends" and "Dividend Policy." Upon the dissolution, liquidation
or winding up of the Company, after payment of debts, expenses and the
liquidation preference plus any accrued dividends on any outstanding shares of
Preferred Stock, the holders of Common Stock will be entitled to receive all
remaining assets of the Company ratably in proportion to the number of shares
held by them. Holders of Common Stock have no preemptive, subscription or
conversion rights and are not subject to further calls or assessments or
rights of redemption by the Company. The shares of Common Stock to be issued
in the Share Exchange and in the Offering will be validly issued, fully paid
and nonassessable.
 
PREFERRED STOCK
 
  The Company's Board of Directors has the authority, without approval of the
shareholders, to issue shares of Preferred Stock in one or more series and to
fix the number of shares and rights, preferences and limitations of each
series. Among the specific matters with respect to the Preferred Stock that
may be determined by the Board of Directors are the dividend rights, the
redemption price, if any, the terms of a sinking fund, if any, the amount
payable in the event of any voluntary liquidation, dissolution or winding up
of the affairs of the Company, conversion rights, if any, and voting powers,
if any.
 
  One of the effects of the existence of authorized but unissued Common Stock
and undesignated Preferred Stock may be to enable the Board of Directors to
make more difficult or to discourage an attempt to obtain control of the
Company by means of a merger, tender offer, proxy contest or otherwise, and
thereby to protect the continuity of the Company's management. If, in the
exercise of its fiduciary obligations, the Board of Directors were to
determine that a takeover proposal was not in the Company's best interest,
such shares could be issued by the Board of Directors without shareholder
approval in one or more transactions that might prevent or make more difficult
or costly the completion of the takeover transaction by diluting the voting or
other rights of the proposed acquiror or insurgent shareholder group, by
creating a substantial voting block in institutional or other hands that might
undertake to support the position of the incumbent Board of Directors, by
effecting an acquisition that might complicate or preclude the takeover, or
otherwise. In this regard, the Company's Articles of Incorporation grant the
Board of Directors broad power to establish the rights and preferences of the
authorized and unissued Preferred Stock, one or more series of which could be
issued that would entitle holders (i) to vote separately as a class on any
proposed merger or consolidation, (ii) to cast a proportionately larger vote
together with the Common Stock on any such transaction or for all purposes,
(iii) to elect directors having terms
 
                                      51
<PAGE>
 
of office or voting rights greater than those of other directors, (iv) to
convert Preferred Stock into a greater number of shares of Common Stock or
other securities, (v) to demand redemption at a specified price under
prescribed circumstances related to a change of control or (vi) to exercise
other rights designated to impede a takeover. The issuance of shares of
Preferred Stock pursuant to the Board of Directors' authority described above
may adversely effect the rights of holders of the Common Stock.
 
  In addition, certain other charter provisions that are described below may
have the effect of, either alone or in combination with each other or with the
existence of authorized but unissued capital stock, of making more difficult
or discouraging an acquisition of the Company deemed undesirable by the Board
of Directors.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
  Advance Notice of Intention to Nominate a Director. The Articles of
Incorporation and By-laws permit a shareholder to nominate a person for
election as a director only if written notice of such shareholder's intent to
make a nomination has been given to the Secretary of the Company not less than
45 days or more than 90 days prior to an annual meeting; however, if less than
55 days notice is given of the meeting, notice by the shareholder must be
received on the 10th day after notice of the meeting was given. This provision
also requires that the shareholder's notice set forth, among other things, a
description of all arrangements or understandings between the nominee and the
shareholder pursuant to which the nomination is to be made or the nominee is
to be elected and such other information regarding the nominee as would be
required to be included in a proxy statement filed pursuant to the proxy rules
promulgated under the Securities Exchange Act of 1934 (the "Exchange Act"), as
amended, had the nominee been nominated by the Board of Directors of the
Company. Any nomination that fails to comply with these requirements may be
disqualified.
 
  Shareholders' Right to Call Special Meeting. The Articles of Incorporation
and By-laws provide that a special shareholders' meeting may be requested by a
shareholder or group of shareholders holding in the aggregate 50% or more of
the Company's total voting power.
 
  Shareholder Action by Unanimous Consent. Under Louisiana law, unless a
corporation's articles of incorporation specify otherwise, shareholders may
only act at a duly called meeting or by unanimous written consent. The
Company's Articles of Incorporation do not contain a provision permitting
action by a consent signed by less than all shareholders.
 
  Removal of Directors; Filling Vacancies on Board of Directors. The Articles
of Incorporation and By-laws provide that any director elected by holders of
the Common Stock may be removed at any time, with or without cause, by a
majority vote of the entire Board of Directors. In addition, any director or
the entire Board may be removed at any time with or without cause by a vote of
the holders of not less than two-thirds of the total voting power held by all
holders of voting stock present or represented at a special stockholders'
meeting called for that purpose. "Cause" is defined for these purposes as
conviction of a felony involving moral turpitude or adjudication of gross
negligence or misconduct in the performance of duties in a matter of
substantial importance to the Company. The Articles of Incorporation and By-
laws also provide that any vacancies on the Board of Directors (including any
resulting from an increase in the authorized number of directors) may be
filled by the affirmative vote of two-thirds of the directors remaining in
office, provided the shareholders shall have the right, at any special meeting
called for that purpose prior to such action by the Board, to fill the
vacancy.
 
  Adoption and Amendment of By-laws. The Articles of Incorporation provide
that the By-laws may be (i) adopted only by a majority vote of the Board of
Directors and (ii) amended or repealed by either a majority vote of the entire
Board of Directors or the holders of two-thirds of the total voting power
present or represented at any shareholders' meeting. Any provisions amended or
repealed by the shareholders may be re-amended or re-adopted by the Board of
Directors.
 
  Consideration of Tender Offers and Other Extraordinary Transactions. Under
Louisiana law, the Board of Directors, when considering a tender offer,
exchange offer, merger or consolidation, may consider, among other
 
                                      52
<PAGE>
 
factors, the social and economic effects of the proposal on the Company, its
subsidiaries and their respective employees, customers, creditors and
communities.
 
  Amendment of Certain Provisions of the Articles of Incorporation; Other
Corporate Action. The Company's Articles of Incorporation require, unless the
action has been approved by a majority vote of the entire Board of Directors,
the affirmative vote of not less than 80% of the total voting power of the
Company to amend, alter or repeal the provisions of the Articles of
Incorporation relating to (i) the filling of vacancies and removal of the
Board of Directors, (ii) amendments to the By-laws, (iii) the Company's
election not to be governed by certain Louisiana laws relating to business
combinations, (iv) limitation of liability and indemnification of directors
and officers, (v) amendments to the Articles of Incorporation and (vi) the
calling of meetings of shareholders. An amendment to the Articles of
Incorporation not affecting any of such provisions may be approved by vote of
a majority of the voting power present or represented at a meeting of
shareholders. The Articles of Incorporation also require the vote of 80% of
the total voting power to approve an amendment or a repeal of any provisions
of the Articles of Incorporation in a way that would reduce the limitation of
liability or indemnification of any person or power of the Board of Directors
with respect thereto provided for in the Articles of Incorporation. Unless
approved by a vote of at least a majority of the Board of Directors, a merger,
consolidation, sale of all or substantially all of the assets or a voluntarily
dissolution of the Company may be authorized only by the affirmative vote of
the holders of 80% of the total voting power. If approved by two-thirds of the
entire Board of Directors, any such action may be authorized by vote of a
majority of the voting power present or represented at a meeting of
shareholders.
 
  The provisions of the Company's Articles of Incorporation and By-laws
summarized in the preceding paragraphs may have anti-takeover effects and may
delay, defer or prevent a tender offer or takeover attempt that a shareholder
might consider in such shareholder's best interest, including those attempts
that might result in the payment of a premium over the market price for the
shares of Common Stock held by such shareholder.
 
  Louisiana Control Share Acquisition Statute. The Louisiana Control Share
Acquisition Statute provides that any shares acquired by a person or group (an
"Acquiror") in an acquisition that causes such person or group to have the
power to direct the exercise of voting power in the election of directors in
excess of 20%, 33 1/3% or 50% thresholds shall have only such voting power as
shall be accorded by the holders of all shares other than "interested shares,"
as defined below, at a meeting called for the purpose of considering the
voting power to be accorded to such shares. "Interested shares" include all
shares as to which the Acquiror, any officer of a company and any director of
a company who is also an employee of a company may exercise or direct the
exercise of voting power. If a meeting of shareholders is held to consider the
voting rights to be accorded to any Acquiror and the shareholders do not vote
to accord voting rights to such shares, a company may have the right to redeem
the shares held by the Acquiror for their fair value. The statute permits the
articles of incorporation or by-laws of a company to exclude from the
statute's application acquisitions occurring after the adoption of the
exclusion. The Company's By-laws do contain such an exclusion; however, the
Company's Board of Directors or shareholders, by amendment to this provision
of the By-laws, could reverse this election.
 
LIMITATIONS ON FOREIGN OWNERSHIP OF COMPANY STOCK
 
  The Company's Articles of Incorporation contain provisions designed to
assure that not more than 24% of its outstanding shares of Common Stock are
owned by persons who are not U.S. citizens. The Articles of Incorporation
provide that any transfer or purported transfer of shares of Common Stock that
would result in the ownership by persons who are not U.S. citizens of more
than 24% of the then outstanding shares of Common Stock will not become
effective against the Company, and the Company has the power to deny voting
and dividend rights with respect to such shares and, at its option, to redeem
such shares.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is       .

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of the Offering, the Company will have 15,500,000 shares of
Common Stock outstanding. The 3,500,000 shares of Common Stock sold in the
Offering (plus any additional shares sold upon the Underwriters' exercise of
their over-allotment option) will be freely transferable without restriction
under the Securities Act by persons who are not deemed to be affiliates of the
Company or acting as underwriters, as those terms are defined in the
Securities Act. The remaining 12,000,000 shares of Common Stock held by
existing shareholders were acquired in transactions not requiring registration
under the Securities Act and will be "restricted" stock within the meaning of
Rule 144. Consequently, such shares may not be resold unless they are
registered under the Securities Act or are sold pursuant to an applicable
exemption from registration, such as Rule 144 under the Securities Act.
 
  In general, under Rule 144 as currently in effect, if at least one year has
elapsed since shares of Common Stock that constitute restricted stock were
last acquired from the Company or an affiliate of the Company, the holder is
entitled to sell within any three-month period a number of shares that does
not exceed the greater of one percent of the total shares of Common Stock then
outstanding or the average weekly trading volume of the Common Stock in the
over-the-counter market during the four calendar weeks preceding the date on
which notice of the sale is filed with the Securities and Exchange Commission.
Sales under Rule 144 are subject to certain manner of sale provisions, notice
requirements and the availability of current public information about the
Company. If at least two years have elapsed since the shares were last
acquired from the Company or an affiliate, a person who has not been an
affiliate of the Company at any time during the three months preceding the
sale is entitled to sell such shares under Rule 144(k) without regard to
volume limitations, manner of sale provisions, notice requirements or the
availability of current public information concerning the Company. None of the
12,000,000 shares of restricted stock within the meaning of Rule 144 held by
existing shareholders of the Company will be eligible for sale in reliance on
Rule 144 until one year after the date of the Share Exchange.
 
  The Company, Advantage Capital and each of its directors and its executive
officers have agreed that they will not, with certain limited exceptions,
issue, offer for sale, sell, or otherwise dispose of any shares of Common
Stock (other than stock issued or options granted pursuant to the Company's
stock incentive plans) for 180 days following the date of this Prospectus
without the prior written consent of Lehman Brothers Inc. See "Underwriting."
 
  Prior to the Offering, there has been no public market for the Common Stock,
and there can be no assurance that a significant public market for the Common
Stock will develop or be sustained after the Offering. Any future sale of
substantial amounts of Common Stock in the open market may adversely affect
the market price of the Common Stock offered hereby.

  The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public at the initial
public offering price set forth on the cover page hereof, and to certain
dealers at such initial public offering price less a selling concession not in
excess of $    per share. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of $    per share to certain other
Underwriters or to certain other brokers or dealers. After the initial
offering to the public, the offering price and other selling terms may be
changed by the Representatives.
 
  The Underwriting Agreement provides that the obligations of the 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, including the condition that no stop order suspending the
effectiveness of the Registration Statement is in effect and no proceedings
for such purpose are pending or threatened by the Commission and that there
has been no material adverse change or development involving a prospective
material adverse change in the condition of the Company from that set forth in
the Registration Statement otherwise than as set forth or contemplated in this
Prospectus, and that certain certificates, opinions and letters have been
received from the Company and its counsel. The Underwriters are obligated to
take and pay for all of the above shares of Common Stock if any such shares
are taken.
 
  The Company and the Underwriters have agreed in the Underwriting Agreement
to indemnify each other against certain liabilities, including liabilities
under the Securities Act, and to contribute to payments that such parties may
be required to make in respect thereof.
 
  The Company has granted to the Underwriters an option to purchase up to an
additional 525,000 shares of Common Stock, exercisable solely to cover over-
allotments, at the initial public offering price, less the underwriting
discounts and commissions shown on the cover page of this Prospectus. Such
option may be exercised at any time until 30 days after the date of the
Underwriting Agreement. To the extent that the option is exercised, each
Underwriter will be committed, subject to certain conditions, to purchase a
number of the additional shares of Common Stock that is proportionate to such
Underwriter's initial commitment as indicated on the preceding table.
 
  The Company, Advantage Capital and the executive officers and directors of
the Company have agreed that they will not, without the prior written consent
of Lehman Brothers Inc., during the 180 days following the date of this
Prospectus, (i) offer for sale, sell, pledge or otherwise dispose of any
shares of Common Stock or any
 
                                      55
<PAGE>
 
securities convertible into, or exchangeable for, shares of Common Stock,
other than in the case of the Company, shares issued or options granted
pursuant to the Stock Incentive Plan or (ii) enter into any swap or other
derivatives transaction that transfers to another, in whole or in part, any of
the economic benefits or risks of ownership of such shares of Common Stock;
provided, however, that the Company may issue shares of Common Stock in
connection with the acquisition of American Helicopter.
 
  The Representatives have informed the Company that the Underwriters do not
intend to confirm sales in excess of five percent of the total number of
shares offered hereby to accounts over which they exercise discretionary
authority.
 
  Until the distribution of the Common Stock is completed, the rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase shares of Common Stock. As an exception to
these rules, the Representatives are permitted to engage in certain
transactions that stabilize the price of the Common Stock. Such transactions
may consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of the Common Stock.
 
  In addition, if the Representatives over-allot (i.e., if they sell more
shares of Common Stock than are set forth on the cover page of this
Prospectus), and thereby create a short position in the Common Stock in
connection with the Offering, the Representatives may reduce that short
position by purchasing Common Stock in the open market. The Representatives
may also elect to reduce any short position by exercising all or part of the
over-allotment option described herein.
 
  The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group
members who sold those shares as part of the Offering.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
the Offering.
 
  Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price will be negotiated between the Company and
the Representatives. Among the factors considered in determining the initial
public offering price of the Common Stock, in addition to prevailing market
conditions, are recent financial and operating results of the Company, the
proposed capital structure, assets and liabilities of the Company, estimates
of the business potential and earnings prospects of the Company, the prospects
for the industry in which the Company operates, an assessment of the Company's
management, consideration of the above factors in relation to market valuation
of companies in related businesses and other factors deemed relevant. The
initial public offering price set forth on the cover page of this Prospectus
should not, however, be considered an indication of the actual value of the
Common Stock. Such price will be subject to change as a result of market
conditions and other factors. There can be no assurance that an active trading
market will develop for the Common Stock or that the Common Stock will trade
in the public market subsequent to the Offering at or above the initial public
offering price.
 
  Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the
transactions described above may have on the price of the Common Stock. In
addition, neither the Company nor any of the Underwriters makes any
representation that the Representatives will engage in such transactions or
that such transactions, once commenced, will not be discontinued without
notice.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To OMNI Energy Services Corp.:
 
  We have audited the accompanying balance sheet of OMNI Energy Services Corp.
(a Louisiana corporation) as of September 15, 1997. This balance sheet is the
responsibility of the Company's management. Our responsibility is to express
an opinion on this balance sheet based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the balance sheet is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the balance sheet. 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 audit provides a reasonable basis for our
opinion.
 
  In our opinion, the balance sheet referred to above presents fairly, in all
material respects, the financial position of OMNI Energy Services Corp. as of
September 15, 1997, in conformity with generally accepted accounting
principles.

                             NOTE TO BALANCE SHEET
 
  OMNI Energy Services Corp. (the "Company") was formed on September 11, 1997
and will issue 12,000,000 shares of its common stock in exchange for all of
the outstanding common units of OMNI Geophysical, L.L.C. (the "Share
Exchange"). Furthermore, at the completion of the Share Exchange, the Company
will publicly offer for sale 3,500,000 shares of common stock. The Company
will have no significant operations or assets prior to the Share Exchange.
 
  In September 1997, the Company adopted a Stock Incentive Plan (the "Plan")
under which both qualified and nonqualified stock options, restricted stock,
and other stock-based compensation awards may be granted. A total of 1,500,000
shares of common stock may be issued under the Plan. The Plan will be
administered by a committee of the Board which selects the individuals
eligible for the various incentives, and, as applicable, determines the number
of shares, option price, vesting schedule, performance measurements and
duration of the award. In the case of qualified options, the exercise price
cannot be less than the fair market value on the date of grant. In connection
with the Offering, the Company will issue options with exercise prices equal
to the initial public offering price to purchase 972,000 shares of Common
Stock to employees and directors of the Company.
 
  The Company plans to account for employee stock-based compensation using the
intrinsic value method prescribed in Accounting Principles Board (APB) Opinion
No. 25, "Accounting for Stock Issued to Employees." Accordingly, the
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," will
not affect the Company's reported results of operations and will be included
as separate pro forma disclosures only.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of Omni Geophysical, L.L.C.:
 
  We have audited the accompanying consolidated balance sheets of Omni
Geophysical, L.L.C., a Louisiana limited liability company (the "Company") and
successor to Omni Geophysical Corporation ("predecessor"), and subsidiaries as
of December 31, 1996, and the related consolidated statements of income, cash
flows and changes in equity for the 165-day period ended December 31, 1996. In
addition, we have audited the consolidated balance sheets of the predecessor
and its subsidiaries as of December 31, 1995 and their consolidated statements
of income, cash flows and changes in equity for each of the two years in the
period then ended and the 201-day period ended July 19, 1996. 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, (a) the financial position of Omni Geophysical,
L.L.C. and subsidiaries as of December 31, 1996 and the results of their
operations and cash flows for the 165-day period then ended and (b) the
financial position of the predecessor and its subsidiaries as of December 31,
1995 and their results of operations and cash flows for each of the two years
in the period then ended and for the 201-day period ended July 19, 1996, all
in conformity with generally accepted accounting principles.

  The purchase method of accounting was used to record assets acquired and
liabilities assumed by the Company. Such accounting generally results in
increased depreciation and amortization expense reported in future periods.
Accordingly, the accompanying financial statements of the predecessor and the
Company are not comparable in all material respects since those financial
statements report the financial position, results of operations and cash flows
of these two separate entities.

  The purchase method of accounting was used to record assets acquired and
liabilities assumed by the Company. Such accounting generally results in
increased depreciation and amortization expense reported in future periods.
Accordingly, the accompanying financial statements of the predecessor and the
Company are not comparable in all material respects since those financial
statements report the financial position, results of operations and cash flows
of these two separate entities.

          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)
 
1. NATURE OF BUSINESS AND OPERATIONS:
 
  Omni Geophysical, L.L.C. (the Company) was formed in 1996 as a Louisiana
limited liability company. The Company acquired substantially all of the
assets and liabilities of OMNI Geophysical Corporation (predecessor) on July
19, 1996. The acquisition was accounted for as a purchase with the assets
acquired and liabilities assumed recorded at their estimated fair value. The
purchase price of approximately $13,300,000 was financed through the sale of
preferred units for $4,000,000, the proceeds from a $7,000,000 asset-based
loan and a $2,300,000 subordinated note issued to the predecessor. The
allocation of the purchase price to the estimated fair values of assets
acquired and liabilities assumed resulted in goodwill of approximately
$219,000 which is being amortized over a 25-year period on a straight-line
basis. The accompanying financial statements include the predecessor's balance
sheet as of December 31, 1995 and results of operations for the two years
ended December 31, 1995 and 201-day period ended July 19, 1996.
 
  The Company is an oilfield service company specializing in providing an
integrated range of onshore seismic drilling, helicopter support and survey
services to geophysical companies operating in logistically difficult and
environmentally sensitive terrain in the United States. The Company's primary
market is the marsh, swamp, shallow water and contiguous dry land areas along
the U.S. Gulf Coast, where the Company is the leading provider of seismic
drilling services.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Use of Estimates in the Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Recent Pronouncements
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 ("SFAS No. 128"), "Earnings Per
Share," which adopts a revised methodology for computing earnings per share
for publicly owned companies. The Company will be required to adopt the new
methodology in the fourth quarter of 1997. Early adoption of SFAS No. 128 is
not permitted.
 
 Revenue Recognition
 
  The Company recognizes revenues as services are rendered. Revenue from the
Company's drilling operations is recognized on a per hole basis. Once the
Company has drilled and loaded a source point, revenue from the drilling of
such source point is recognized. Similarly, revenue is recognized from the
Company's seismic survey operations when the source or receiving point is
marked by one of the Company's survey crews. The Company's aircraft, which are
usually chartered for a guaranteed minimum number of hours per day, generate
revenue pursuant to a fixed hourly rate.
 
 Accounts Receivable
 
  Trade and other receivables are stated at net realizable value and the
allowance for uncollectible accounts was approximately $125,000 as of June 30,
1997 and December 31, 1996, and $15,000 as of December 31, 1995 and 1994. The
Company grants credit to its customers on a short-term basis.

          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)
 
 Inventories
 
  Inventories consist of parts and supplies used for drilling equipment and
services. All inventories are valued at lower of cost or market.
 
 Property and Equipment
 
  Property and equipment are stated at cost less accumulated depreciation. The
Company provides for depreciation by charges to operations in amounts
estimated to allocate the cost of the assets over their estimated useful lives
and salvage values as follows:

  Additions to property and equipment and major replacements are capitalized.
Gains and losses on dispositions, maintenance, repairs and minor replacements
are reflected in current operations. Drilling equipment which is fabricated is
comprised of direct and indirect costs incurred during fabrication. Costs
include materials and labor consumed during fabrication. Interest is also
capitalized during the fabrication period.
 
  In March 1995, the Financial Accounting Standards Board issued SFAS No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of." This statement requires that long-lived assets be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying value of an asset may not be realizable. The Company adopted SFAS No.
121 effective January 1, 1996; the adoption of this statement did not have an
effect on the Company's consolidated financial statements.
 
 Income Taxes
 
  The Company is treated as a partnership for income tax purposes. Income
taxes are the responsibility of the individual members. Accordingly, no
provision for income taxes has been made in the accompanying financial
statements.
 
  As discussed in Note 10, the members of the Company will exchange (the
"Share Exchange") all of their common units in the Company (103,263 as of June
30, 1997) for 10,919,983 shares of common stock of OMNI Energy Services Corp.
("OMNI"). The Share Exchange will be accounted for as a reorganization whereby
the assets and liabilities transferred will be accounted for at their
historical cost in a manner similar to that in a pooling-of-interest. OMNI
will then be subject to federal and state income taxes. This will result in
OMNI providing income taxes beginning in the fourth quarter of 1997.
 
  The pro forma provision for income taxes is the result of the application of
a combined federal and state income tax rate (40%) to income before income
taxes.
 
 Unaudited Pro Forma June 30, 1997 Balance Sheet Data and Unaudited Pro Forma
Earnings Per Share
 
  The pro forma financial information reflects (i) the Share Exchange, (ii)
the distribution by the Company to its members all of its retained earnings,
approximately $3.7 million as of June 30, 1997, and (iii) the redemption

          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)


of all the outstanding preferred units of the Company (Note 8). The
distributions are expected to be funded through long-term borrowings. The
unaudited pro forma balance sheet data as of June 30, 1997, reflects the
effects of the above transactions as if they had occurred as of that date. The
unaudited pro forma balance sheet data should not be considered indicative of
actual balance sheet data subsequent to such transactions. The pro forma
weighted average number of shares of common stock, for all periods presented,
gives effect to the Share Exchange and the exercise of 118,018 options granted
outside of the Company's stock incentive plan (Note 9).

7. COMMITMENTS AND CONTINGENCIES:
 
  In connection with the acquisition of the assets of OMNI Geophysical
Corporation discussed in Note 1, the Company also entered into a five-year
lease agreement with OMNI Geophysical Corporation to lease the main office
facility. The monthly lease payment under the agreement is $5,000 through July
2001. The agreement also allows the Company to renew the lease for two
additional five-year periods.
 
  The Company carries workers compensation insurance coverage with a
deductible amount of $200,000 per incident for claims incurred in 1996. This
deductible was raised to $250,000 in 1997. Management of the Company is not
aware of any significant workers compensation claim or an incurred but not
reportable claim as of June 30, 1997.
 
8. PREFERRED UNITS:
 
  In connection with the Company's acquisition of OMNI Geophysical Corporation
on July 19, 1996 (Note 1), the Company issued 4,000, 10% cumulative
participating preferred units in the 165-day period ended December 31, 1996
and 1,000, 15% cumulative participating preferred units in the six months
ended June 30, 1997, respectively. The Company may redeem the preferred units
at a redemption price equal to the sum of the cumulative unpaid dividends to
date plus the units' redemption price of $1,000 per unit. Cumulative unpaid
dividends totaled approximately $180,000 and $352,000 at December 31, 1996 and
June 30, 1997, respectively.
 
9. STOCK OPTIONS:
 
  In April and June 1997, the Company issued options to purchase 516 and 600
common units, respectively, (equivalent to 54,567 and 63,451 shares of Common
Stock calculated on the pro forma share basis described in Note 2). The
exercise price of each option is $2.28 (on the pro forma share basis described
in Note 2) which approximated their fair value on the date of grant. The
options vest ratably over three years and expire if unexercised after ten
years.
 
  The Company plans to account for employee stock-based compensation using the
intrinsic value method prescribed in Accounting Principles Board (APB) Opinion
No. 25, "Accounting for Stock Issued to Employees." Accordingly, the
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," will
not affect the Company's reported results of operations and will be included
as separate pro forma disclosures only.
 
  The Company has entered into employment agreements with its key executive
officers which include respective base salaries and terms of employment.

10. SUBSEQUENT EVENTS:
 
  The members of the Company intend to undertake the Share Exchange as
described in Note 2 to facilitate an initial public offering of the common
stock of OMNI during 1997. Proceeds are intended to be used to retire
outstanding debt and for general corporate purposes, including acquisitions,
capital expenditures and working capital. There can be no assurance, however,
that the offering will occur or that the proceeds, if any, will be sufficient
for their intended use.
 
11. ACQUISITIONS:
 
  On March 21, 1997, the Company acquired the assets and assumed certain
liabilities of Delta Surveys, Inc., a surveying business, for $180,000 in cash
and a $120,000, 8.5%, three year promissory note. This acquisition was
accounted for using the purchase method of accounting. The excess of cost of
approximately $200,000 over the estimated fair value of the net assets
acquired is included in goodwill and is being amortized over twenty-five years
using the straight-line method.
 
  Effective July 1, 1997, the Company acquired substantially all of the assets
and liabilities of American Aviation Incorporated (American Aviation), a
company that operates aircraft for various seismic drilling support services.
In consideration for the acquisition of American Aviation, the Company issued
to the sellers 10,213 common units of the Company (equivalent to 1,080,017
shares of Common Stock) valued at approximately $2.5 million, a $1.0 million
promissory note bearing interest at 8.5%, paid $500,000 cash and assumed
approximately $6.7 million in debt.
 
  Effective July 1, 1997, the Company acquired Leonard J. Chauvin, Jr., Inc.
("Chauvin"), a surveying company, for $788,000 cash and up to an additional
$100,000 based on the future earnings of Chauvin through August 31, 1999.
 
  Effective September 1, 1997, the Company acquired substantially all the
assets of O.T.H. Exploration Services, Inc., a seismic rock drilling company,
headquartered in the Rocky Mountain region. The aggregate purchase price was
$600,000 cash.
 
  On September 10, 1997, the Company entered into a non-binding letter of
intent to acquire American Helicopter Drilling, Inc. ("American Helicopter")
for $750,000 in cash and $2.75 million in Common Stock. American Helicopter
engages in seismic drilling services in the Rocky Mountain area and in the
fabrication, export and servicing of heli-portable and other seismic drilling
units. The acquisition of American Helicopter is anticipated to occur on or
before January 31, 1998. There can be no assurance that this acquisition will
be consummated.

                        AMERICAN AVIATION INCORPORATED
 
                         NOTES TO FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1996 AND 1995
          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)
 
1. NATURE OF BUSINESS AND OPERATIONS:
 
  American Aviation Incorporated (the Company) was formed on November 1, 1995,
as a Louisiana corporation. The Company primarily operates aircraft for
various seismic drilling support services to the geophysical segment of the
oil and gas exploration and production industry.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Use of Estimates in the Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  The Company recognizes revenues as services are rendered. The Company's
aircraft, which are usually chartered for a guaranteed minimum number of hours
per day, generate revenue pursuant to a fixed hourly rate.
 
 Accounts Receivable
 
  Accounts receivable are stated at net realizable value. The Company grants
credit to its customers on a short-term basis.
 
 Fixed Assets
 
  Aircraft, vehicles and other equipment are carried at cost. Major additions,
betterments, and renewals are capitalized. Maintenance and repairs, including
major overhauls, are charged to earnings as incurred. Depreciation and
amortization to estimated residual values are computed on the straight-line
basis over the estimated useful lives and salvage values as follows:
 
<TABLE>
<CAPTION>
                                                                USEFUL   SALVAGE
      ASSET CLASSIFICATION                                       LIFE     VALUE
      --------------------                                     --------- -------
      <S>                                                      <C>       <C>
      Aircraft................................................ 10 years     25%
      Equipment............................................... 5-7 years    --
      Autos and trucks........................................  5 years     --
      Office Equipment........................................ 5-7 years    --
</TABLE>
 
  Long-lived assets to be held and used are reviewed for impairment whenever
events or changes in circumstances indicate that the related carrying amount
may not be recoverable. When required, impairment losses on assets to be held
and used are recognized based on the fair value of the asset.
 
 Income Taxes
 
  The Company is treated as a Subchapter S corporation for income tax
purposes. Income taxes are the responsibility of the individual members.
Accordingly, no provision for income taxes has been made in the accompanying
financial statements.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
                          DECEMBER 31, 1996 AND 1995
          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)
 
  As discussed in Note 8, the Company was acquired by OMNI Geophysical, L.L.C.
(OMNI Geophysical) on July 1, 1997. The members of OMNI Geophysical will
exchange (the Share Exchange) all of their common units in OMNI Geophysical
(103,263 as of June 30, 1997) for 10,919,983 shares of common stock of newly-
formed OMNI Energy Services Corp. (OMNI). The Share Exchange will be completed
in order to facilitate an initial public offering of the common stock of OMNI
in 1997. Upon completion of the Share Exchange, OMNI Geophysical will cease to
be treated as a partnership for federal and state income tax purposes, and
will become subject to federal and state income taxes. This will result in
OMNI providing income taxes beginning in the fourth quarter of 1997.
 
  The pro forma provision for income taxes is the result of the application of
a combined federal and state rate (40%) to income before taxes.
 
3. DEPOSITS AND PREPAID LEASES:
 
  Included in deposits and prepaid leases is a lease deposit on a King-Air 300
airplane totaling approximately $1,401,500 at December 31, 1996. The plane was
subsequently purchased for $1,323,750 and placed into fixed assets in February
1997.
 
4. LONG-TERM DEBT:
 
  Long-term debt is summarized as follows:

                          DECEMBER 31, 1996 AND 1995
          (DATA WITH RESPECT TO JUNE 30, 1997 AND 1996 IS UNAUDITED)
 
5. RELATED PARTY TRANSACTIONS:
 
  Notes payable to shareholder represent advances made by a shareholder to the
Company to fund working capital requirements. The advance bears interest at 8
percent, payable quarterly, with varying maturities through December 1997.
Accrued interest payable at December 31, 1996 is approximately $20,000.
 
  During the year, the Company purchased a Bell 206B-III helicopter. The
aircraft was sold to OMNI Geophysical LLC, a company affiliated through common
ownership, for $526,000, resulting in a gain to the Company of $220,644.
 
6. CUSTOMER CONCENTRATION:
 
  Substantially all of the Company's revenues are derived from customers in
the geophysical industry. During the fiscal year ended December 31, 1996, five
customers accounted for approximately 86% of the Company's total revenues.
Included in accounts receivable are amounts owed from these five customers
totaling approximately $1,089,000, which is approximately 89% of total
receivables.
 
7. OPERATING LEASES:
 
  The Company leases aircraft for use on its jobs under agreements classified
as operating leases. The leases are short-term in nature. The Company also
leases a hangar and office space at the Lafayette Regional Airport under an
operating lease.
 
  Operating lease expense in 1996 was approximately $885,000. The future
minimum lease payments are $182,126 and $50,000 for the years ended December
31, 1997 and 1998, respectively.
 
8. SUBSEQUENT EVENTS:
 
  Subsequent to year end, the Company was purchased by OMNI Geophysical,
L.L.C. The combination was accounted for under the purchase method, and the
effective date of the purchase was July 1, 1997.

31, 1996 and the period ended June 30, 1997 are not significant. The
acquisition of substantially all the assets of American Aviation was accounted
for using the purchase method of accounting.
 
  The following unaudited pro forma condensed consolidated financial
statements should be read in conjunction with the historical consolidated

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Louisiana Business Corporation Law (the "LBCL"), Section 83, (i) gives
Louisiana corporations broad powers to indemnify their present and former
directors and officers and those of affiliated corporations against expenses
incurred in the defense of any lawsuit to which they are made parties by
reason of being or having been such directors or officers; (ii) subject to
specific conditions and exclusions, gives a director or officer who
successfully defends such an action the right to be so indemnified; and (iii)
authorizes Louisiana corporations to buy directors' and officers' liability
insurance. Such indemnification is not exclusive of any other rights to which
those indemnified may be entitled under any by-law, agreement, authorization
of shareholders or otherwise.
 
  The Company's By-laws make mandatory the indemnification of directors and
officers permitted by the LBCL. The standard to be applied in evaluating any
claim for indemnification (excluding claims for expenses incurred in
connection with the successful defense of any proceeding or matter therein for
which indemnification is mandatory without reference to any such standard) is
whether the claimant acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the Company. With
respect to any criminal action or proceeding, the standard is that the
claimant had no reasonable cause to believe the conduct was unlawful. No
indemnification is permitted in respect of any claim, issue or matter as to
which a director or officer shall have been adjudged by a court of competent
jurisdiction to be liable for willful or intentional misconduct or to have
obtained an improper personal benefit, unless, and only to the extent that the
court shall determine upon application that, in view of all the circumstances
of the case, he is fairly and reasonably entitled to indemnity for such
expenses that the court shall deem proper.
 
  The Company maintains liability policies to indemnify its officers and
directors against loss arising from claims by reason of their legal liability
for acts as officers and directors, subject to limitations and conditions to
be set forth in the policies.
 
  The Underwriters have also agreed to indemnify the directors and certain of
the Company's officers against certain liabilities, including liabilities
under the Securities Act of 1933, as amended (the "Securities Act"), or to
contribute to payments that such directors and officers may be required to
make in respect thereof.
 
  Each of the Company's directors and executive officers has entered into an
indemnity agreement with the Company, pursuant to which the Company has agreed
under certain circumstances to purchase and maintain directors' and officers'
liability insurance. The agreements also provide that the Company will
indemnify the
 
                                     II-1
<PAGE>
 
directors and executive officers against any costs and expenses, judgments,
settlements and fines incurred in connection with any claim involving a director
or executive officer by reason of his position as director or officer that are
in excess of the coverage provided by any such insurance, provided that the
director or officer meets certain standards of conduct. A form of indemnity
agreement containing such standards of conduct is included as an exhibit to this
Registration Statement. Under the indemnity agreements, the Company is not
required to purchase and maintain directors' and officers' liability insurance
if it is not reasonably available or, in the reasonable judgment of the Board of
Directors, there is insufficient benefit to the Company from the insurance.

      be deemed to be a new registration statement relating to the securities
      offered therein, and the offering of such securities at that time shall
      be deemed to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

          business as a foreign corporation and is in good standing in the
          jurisdictions in which it conducts its business (except where the
          failure to so qualify would not have a material adverse effect on the
          business or financial condition of the Business taken as a whole) (the
          "Material Jurisdictions"). There are no such Material Jurisdictions.

               3.4  Authority. The Seller has the corporate power and authority
          to execute and deliver this Agreement and to consummate the

          Seller of this Agreement and the consummation of the transactions
          contemplated hereby have been duly authorized by the Board of
          Directors and shareholders of the Seller; no other corporate
          proceedings on the part of the Seller or any other person or entity,
          whether pursuant to the Articles of Incorporation or Bylaws of the
          Seller or by law or otherwise, are necessary to authorize the Seller

          Jeansonne and constitutes a valid and binding obligation of the Seller
          and Jeansonne, enforceable against both the Seller and Jeansonne in

          affecting creditors' rights generally, (ii) the remedy of specific
          performance and injunctive relief are subject to certain equitable
          defenses and to the discretion of the court before which any

          indemnification hereunder may be limited under applicable securities
          laws.

               3.5  No Violations. Neither the execution or delivery of this
          Agreement nor the consummation of the transactions contemplated

          its properties or assets are subject;

               (c)  Violates or will violate, or conflicts with or will conflict
          with, any provision of, or constitutes a default under, the Articles

          default) under, or give rise to a right to terminate, any mortgage,
          contract, agreement, deed of trust, license, lease, or other
          instrument, arrangement, commitment, obligation, understanding, or
          restriction of any kind to which the Seller is a party or by which its
          properties may be bound, or (ii) will cause, or give any person
          grounds to cause, to be accelerated (with notice or lapse of time or
          both) the maturity of, or will increase, any liability or obligation
          of the Seller.

          ordinary course of business, consistent with past practice, subsequent

          3.7.

               3.8  Certain Tax Matters.

               (a)  All income taxes, unemployment, social security, franchise,
          real property, personal property and all other taxes levied, assessed
          or imposed upon Seller in connection with Seller's operation of the
          Business by the United States, or any state, or governmental
          subdivision of either, to the extent due and payable, have been duly
          paid to date or are being contested through appropriate administrative
          or judicial procedures, and no liability for deficiencies with respect
          thereto exists. There are no tax audits pending nor any outstanding
          agreements or waivers extending the statutory period of limitations
          applicable to any federal, state or local income tax return for any
          period in connection with Seller's operation of the Business. No tax

          withholding, real and personal property tax returns required to be
          filed in connection with Seller's operation of the Business. No

          the late filing of any return by Seller in connection with Seller's
          operation of the Business. True, correct and complete copies of the
          state and local real property and personal property tax returns of
          Seller in connection with Seller's operation of the Business for

                    (iii)  Is not subject to any (A) claims, audits, actions,
          suits, proceedings, or investigations with respect to any Tax or
          assessment for which the Purchaser could be liable, which would be
          material to the Business, and (B) requests for rulings in respect of
          any Tax or any proposed transaction pending before any Taxing
          Authority (as defined in Section 5.2 of this Agreement).

               (c)  None of the directors or officers of the Seller is aware of
          any state of facts that could give rise to any claim, audit, action,
          suit, proceeding, or investigation with respect to any Tax or
          assessment for which the Purchaser could be liable and which would be
          material.

               (d)  No Tax or assessment will be assessed on or after the
          Closing Date against or pertaining to any assets of the Business for
          any tax period ending on or prior to the Closing Date, or for any
          period ending after the Closing Date with respect to any portion of
          such tax period that includes or is prior to the Closing Date other
          than a Tax disclosed on Schedule 3.8(d). "Tax" or "Taxes" shall mean
          all taxes, charges, fees, levies or other assessments including,
          without limitation, income, excise, property, withholding, sales and

          by the United States, or any state, county, local or foreign
          government or subdivision or agency thereof, and including any
          interest, penalties or additions attributable thereto.

               3.9  Condition of Facilities. The facilities included in the
          Assets, including equipment, furniture, vehicles and other tangible
          personal property, are in good operating condition and repair,
          ordinary wear and tear excepted and are in adequate working order for
          the continued conduct of the Business as it is currently conducted and
          Seller has no knowledge of any condition or defect, not disclosed
          herein, in any of the Assets which would materially affect the fair
          market value, use or operation of the Business, such as to have a

          transactions contemplated hereby).

               (b)  (i)  The Seller has incurred no indebtedness or liabilities
          which may bear against the Assets of the Business except those listed

          with its terms, no Lease has been modified or amended in writing, and
          the Seller has not received any written notice of any breach or
          default with respect to a Lease the consequences of which would result
          in such Lease being terminated by the lessor or which, individually or
          in the aggregate, would have a material adverse effect on the business
          or financial condition of the Business taken as a whole.

               (a)  (i)    The Seller has the sole and exclusive right to use
          the Intangible Property referred to in Section 1.1(a)(ii), and the
          consummation of the transactions contemplated by this Agreement will
          not alter or impair any such rights and will result in the Purchaser
          having the sole and exclusive right to use all such Intangible
          Property used in the Business;

                    (ii)   The Seller has the right to use all Intangible
          Property which is currently used by the Seller in connection with the
          Business either as provided in clause (i) above or as licensed or
          authorized by others, and the consummation of the transactions
          contemplated by this Agreement will not alter or impair any such
          rights and will result in the Purchaser having the right to use all
          such Intangible Property to the same extent it is currently used in
          the Business;

                    (iii)  No claims have been asserted by any person or entity
          for the use of any such Intangible Property or challenging or
          questioning the validity or effectiveness of any such license or
          agreement, and the Seller has no knowledge of any valid basis for any
          such claim; and

                    (iv)   To the knowledge of the Seller, the use of such
          Intangible Property by the Seller does not infringe on the rights of
          any person or entity and no proceedings have been instituted, are
          pending, or, to the best of Sellers' knowledge, threatened that
          challenge the rights of the Seller in respect thereof.

                    (v)    None of Seller's Intangible Property rights, to the
          best of Seller's knowledge, are being infringed by the products,
          activities, operations, trade names, trademarks, service marks, trade
          dress rights or copyrights of any other person or persons and none are
          subject to any outstanding order, judgment, decree, stipulation or
          agreement restricting the use thereof.

               3.14 Insurance. The Seller has heretofore made available for
          inspection by the Purchaser a true and complete copy of all policies
          of fire, liability, workers' compensation, and other forms of
          insurance owned or held by the Seller. All such policies are in full
          force and effect, all premiums with respect thereto covering all
          periods up to and including the Closing Date have been paid, and no
          notice of cancellation or termination has been received with respect
          to any such policy. Such policies are in such amounts and insure
          against such losses and risks and provide such coverage as, in the
          opinion of the Seller, is adequate to protect the Business as it is
          currently conducted.

               3.15 No Benefit Plans; Absence of PBGC Lien. Neither the Seller
          nor any Affiliate (as defined in Section 5.2 of this Agreement)
          maintains any "employee benefit plan" as defined in Section 3(3) of
          the Employee Retirement Income Security Act of 1974, as amended, and
          the rules and regulations promulgated thereunder, that covers any
          employee or former employee of the Seller. None of the Assets are
          subject to a lien in favor of the Pension Benefit Guaranty
          Corporation.

          involving the Seller or any directors, officers, or employees thereof
          in their capacity as such or that question or challenge the validity
          of this Agreement, or any action taken or to be taken by the Seller
          pursuant to this Agreement or in connection with the transactions
          contemplated hereby, and to the knowledge of the Seller, there is no
          valid basis for any such Action. No Action set forth in Schedule 3.21
          would, if adversely decided, have a material adverse effect on the
          Business taken as a whole or, after the Closing Date, on the ability
          of the Purchaser to conduct the Business.

          without limitation, those related to public or occupational safety,
          pollution and protection of the environment, and hazardous or other
          waste disposal). The Seller has not received any written notification
          of any asserted present failure to comply with any Law, except for
          failures that in the aggregate are not and were not material to the
          conduct of the Business as a whole and which the Seller has taken

          Seller, no customer of supplier of the Seller will cease to do

          Business. Seller has not experienced any difficulties in obtaining any
          inventory, supplies, equipment or other items necessary to the

          any shareholder, officer, director or employee of the Seller, nor any
          spouse or child of any of them, as any direct or indirect

          thereof, the Indemnitors shall be liable for the fees and expenses of
          counsel employed by any Indemnitee; provided, however, that the
          Indemnitors shall not be liable for the fees or expenses of more than

          Indemnitees. If the Indemnitees assume the defense thereof, the
          Indemnitees shall thereafter consult with the Indemnitors upon the
          Indemnitors' reasonable request for such consultation from time to
          time with respect to such suit, action, or proceeding and the
          Indemnitees shall not, without the Indemnitors' consent, which consent
          shall not be unreasonably withheld, settle or compromise any such
          suit, action. or claim. Whether or not the Indemnitors choose to
          defend or prosecute any claim, all of the parties hereto shall
          cooperate in the defense or prosecution thereof.

               (b)  No investigation by any Indemnitee or Indemnitee Affiliate
          prior to the Closing Date shall relieve any Indemnitor of any
          liability hereunder.

               5.4  Cooperation on Tax Matters. The Seller and the Purchaser
          shall cooperate fully, as and to the extent reasonably requested by
          the other party, in connection with any audit, litigation, or other
          proceeding with respect to Taxes. Such cooperation shall include the
          retention and (upon the other party's request) the provision of
          records and information which are reasonably relevant to any such
          audit, litigation, or other proceeding and making employees available
          on a mutually convenient basis to provide additional information and
          explanation of any material provided hereunder. The Purchaser and the
          Seller agree (a) to retain all books and records which are relevant to
          the determination of the Tax liabilities pertinent to the Assets
          relating to any Pre-Closing Tax Period until the expiration of the
          applicable statute of limitations and to abide by all record retention
          agreements entered into with any Taxing Authority, and (b) to give the
          other party reasonable written notice prior to destroying or
          discarding any such books and records and, if the other party so
          requests, the Purchaser or the Seller, as the case may be, shall allow
          the other party to take possession of such books and records.


                                      SECTION 6
                              MISCELLANEOUS PROVISIONS

               6.1  Amendment and Modification. This Agreement may be amended,
          modified, or supplemented only by written agreement of the parties
          hereto.

               6.2  Waiver of Compliance; Consents. Any failure of a party to
          comply with any obligation, covenant, agreement, or condition herein
          may be waived by the other party; provided,


                                      21
<PAGE>
 
          however, that any such waiver may be made only by a written Instrument
          signed by the party granting such waiver, but such waiver or failure
          to insist upon strict compliance with such obligation, covenant,
          agreement, or condition shall not operate as a waiver of, or estoppel
          with respect to, any subsequent or other failure. Whenever this
          Agreement requires or permits consent by or on behalf of any party
          hereto, such consent shall be given in writing in a manner consistent
          with the requirements for a waiver of compliance as set forth in this
          Section 6.2, with appropriate notice in accordance with Section 6.9 of
          this Agreement.

               6.3  Assignment. This Agreement and all of the provisions hereof
          shall be binding upon and inure to the benefit of the parties hereto
          and their respective successors and permitted assigns. Any party may
          assign any of its rights hereunder, but no such assignment shall
          relieve it of its obligations hereunder. Nothing in this Agreement,
          expressed or implied, is intended or shall be construed to confer upon
          any person other than the parties, any successors and permitted
          assigns, any rights, remedy, or claim under or by reason of this
          Agreement or any provisions herein contained.

               6.4  Expenses, Transfer Taxes, Etc. Whether or not the
          transactions contemplated by this Agreement shall be consummated, all
          fees and expenses (including all fees of counsel, actuaries,
          accountants and other experts) incurred by any party in connection
          with the negotiation and execution of this Agreement shall be borne by
          such party.

               6.5  Further Assurances. From time to time, at the request of the
          Seller or the Purchaser and without further consideration, each party,
          at its own expense, will execute and deliver such other documents, and
          take such other action, as the Seller or the Purchaser may reasonably
          request in order to consummate more effectively the transactions
          contemplated hereby and to vest in the Purchaser good and marketable
          title to the Assets. The Seller hereby constitutes and appoints,
          effective as of the Closing Date, the Purchaser and its successors and
          permitted assigns as the true and lawful attorney of the Seller with
          full power of substitution in the name of the Purchaser or in the name
          of the Seller, but for the benefit of the Purchaser, to collect for
          the account of the Purchaser any items of Assets and to institute and
          prosecute all proceedings that the Purchaser may in its reasonable
          discretion deem proper in order to assert or enforce any right, title,
          or interest in, to, or under the Assets, and to defend or compromise
          any and all action, suits, or proceedings in respect of the Assets.
          The Purchaser shall be entitled to retain for its own account any

                                     by and among
                           AMERICAN AVIATION INCORPORATED,
                               AMERICAN AVIATION L.L.C.
                                         and
                               OMNI GEOPHYSICAL, L.L.C.
                               Dated as of July 1, 1997


               THIS EXCHANGE AGREEMENT (the "Agreement") is made and entered
          into on the 5th day of August, 1997 (the "Closing Date") but effective
          as of July 1, 1997 (the "Effective Date") by and among AMERICAN
          AVIATION INCORPORATED ("American"), AMERICAN AVIATION L.L.C. ("AA")
          and OMNI GEOPHYSICAL, L.L.C. ("Omni"). David Jeansonne, the President
          of American ("Jeansonne"), joins in the execution of this Agreement
          for the purposes of making the representations and warranties set
          forth in Section 3 and agreeing to be bound by the terms of Section 5.

                                       RECITALS

               1.   American, a Louisiana corporation, has been engaged
          primarily in an aviation business based in Louisiana with operations
          on the Gulf Coast (the "Business").

               2.   AA is a Missouri single-member limited liability company,
          qualified to do business in Louisiana, which is wholly owned by Omni.
          AA is a domestic entity with a single owner and has made an election
          on Form 8832 to be disregarded as a separate entity for federal income
          tax purposes.

               3.   American desires to effect the transfer to AA, and AA
          desires to effect the acquisition from American of, all of the assets
          of American (except for those specifically identified items of
          intangible property referred to as Excluded Assets in Section 1.1(a)
          of this Agreement), in exchange for 10,213 Common Units of Omni. It is
          the specific intention of this Agreement that the contribution of
          assets to AA by American in exchange for Common Units (as that term is
          defined in Omni's Operating Agreement, as amended and restated) of
          Omni qualify as a tax-free contribution of property to Omni under
          section 721 of the Internal Revenue Code of 1986, as amended.

               4.   The exchange of the assets by American in exchange for the
          Common Units of Omni and the assumption of liabilities by AA are
          effective as of the Effective Date of this Agreement and are all
          subject to the terms and conditions of this Agreement.

               In consideration of the foregoing and the mutual representations,
          warranties, covenants, and agreements herein contained, American and
          AA agree as follows:

          relating to the fabrication, use, operation, development, sale or
          enjoyment of the Assets;

          of the Tax basis of the Assets (collectively, "Files and Records").

          But specifically excluding the intangible property described in
          Schedule 1.1 (the "Excluded Assets"), which Excluded Assets are being
          sold by American to AA contemporaneously herewith in that certain
          Intangible Asset Purchase Agreement by and among American, AA and Omni
          (the "Intangible Asset Purchase Agreement").

          assignment, transfer, or conveyance, in each case dated as of the date
          executed but effective as of the Effective Date (collectively, the
          "Conveyance Instruments"), as the parties and their respective counsel
          shall reasonably deem necessary or appropriate to vest in or confer
          title to the Assets to AA.

               1.3  Exchange. In exchange for the assignment, transfer, or

               (b)  The copy of the Articles of Incorporation and all amendments
          thereto of American, as certified by the Secretary of State of the

          business as a foreign corporation and is in good standing in the
          jurisdictions in which it conducts its business (except where the

          "Material Jurisdictions").

               3.4  Authority. American has the corporate power and authority to

          entity, whether pursuant to the Articles of Incorporation or Bylaws of
          American or by law or otherwise, are necessary to authorize American

          default) under, or give rise to a right to terminate, any mortgage,
          contract, agreement, deed of trust, license, lease, or other

          any proposed transaction pending before any Taxing Authority (as such
          term is defined in Section 5.2 of this Agreement).

               (c)  None of the directors or officers of American is aware of
          any state of facts that could give rise to any claim, audit, action,
          suit, proceeding, or investigation with respect to any Tax or
          assessment for which AA could be liable and which would be material.

               (d)  No Tax or assessment will be assessed on or after the
          Effective Date against or pertaining to any assets of the Business for
          any tax period ending on or prior to the Effective Date, or for any
          tax period ending after the Effective Date with respect to any portion
          of such tax period that includes or is prior to the Effective Date.

          assessments including, without limitation, income, excise, property,
          withholding, sales and franchise taxes and any other charge in the
          nature of a tax, imposed by the United States, or any state, county,
          local or foreign government or subdivision or agency thereof, and
          including any interest, penalties or additions attributable thereto.

               3.9  Condition of Facilities. The facilities included in the
          Assets, including equipment, furniture, vehicles and other tangible

          ordinary wear and tear excepted and are in adequate working order for
          the continued conduct of the Business as it is currently conducted and
          American has no knowledge of any condition or defect, not disclosed
          herein, in any of the Assets which would materially affect the fair
          market value, use or operation of the Business, such as to have a
          material adverse effect on the Business or its operations.

          including the dollar amounts thereof together with an accurate aging
          thereof. The Receivables have been earned and recorded in the ordinary
          course of business consistent with past practices, and no Receivables
          are subject to any counterclaim or offset. None of the Receivables
          have been sold, transferred, or otherwise disposed of by American. All
          Receivables are fully collectible, except the Grant Receivable.

          incurred in the ordinary course of business subsequent to the date

          amount disputed in good faith and which are marked "Disputed" on
          Schedule 3.10(b).

          notice.

               3.12 Leases.

               (a)  American has delivered or made available to AA a copy of
          each lease pursuant to which American leases real or personal property

          Business, and all goodwill associated with such intangible property
          (collectively, the "Intangible Property"), and the consummation of the
          transactions contemplated by this Agreement and the Intangible Asset
          Purchase Agreement will not alter or impair any such rights and will
          result in AA having the sole and exclusive right to use all such
          Intangible Property used in the Business;

                    (ii)   American has the right to use all Intangible Property
          which is currently used by American in connection with the Business
          either as provided in clause (i) above or as licensed or authorized by

          such claim; and

                    (iv)   To the knowledge of American, the use of such
          Intangible Property by American does not infringe on the rights of any
          person or entity and no proceedings have been instituted, are pending,
          or, to the best of American's knowledge, have been threatened that
          challenge the rights of American in respect thereof.

                    (v)    None of American's Intangible Property rights, to the
          best of American's knowledge, are being infringed by the products,
          activities, operations, trade names, trademarks, service marks, trade

          including the Closing Date have been paid, and no notice of
          cancellation or termination has been received with respect to any such
          policy. Such policies are in such amounts and insure against such
          losses and risks and provide such coverage as, in the opinion of
          American, is adequate to protect the Business as it is currently
          conducted.

               3.15 No Benefit Plans; Absence of PBGC Lien. Neither American nor
          any Affiliate (as defined in Section 5.2 of this Agreement) maintains
          any "employee benefit plan" as defined in Section 3(3) of the Employee
          Retirement Income Security Act of 1974, as amended, and the rules and
          regulations promulgated thereunder, that covers any employee or former
          employee of American. None of the Assets is subject to a lien in favor

          has succeeded to a party by assumption or assignment or in which it
          has a beneficial interest (any contract or agreement shall, for the
          purposes of this Agreement, be deemed material (A) if the Business
          taken as a whole is substantially dependent upon it, (B) if it
          involves a financial obligation of or benefit to the Business in
          excess of $100,000, (C) if the contract is not made in the ordinary
          course, or (D) if it constitutes a management contract or employment
          contract (excluding oral agreements that arise by operation of law),
          but excluding quotations given to customers of American in connection
          with estimates of the cost of future work); and

          with the Business.

               (b)  American does not have (i) any outstanding sales contracts
          or commitments that are reasonably expected to result in any loss to
          the Business upon completion of performance thereof or (ii) any
          outstanding bids or sales or service proposals quoting prices that are
          not reasonably expected to result in a profit consistent with past
          practice.

               (c)  American is not restricted by agreement from carrying on the
          Business anywhere in the world.

               3.17 Labor Matters.

               (a)  Neither American nor any employee employed by American is a
          party to or is covered by any labor agreement with any collective
          bargaining representative representing employees of American.

               (b)  American is operating in material compliance with all
          applicable laws respecting employment and employment practices, terms
          and conditions of employment, and wages and hours, and is not engaged
          in any unfair labor practices and no charges or proceedings before the
          National Labor Relations Board, or similar agency, exist, or to the
          best knowledge of American, are threatened.

               (c)  There are no unfair labor practice complaints, labor

          actions exist under any federal, state or local laws affecting the
          employment relationship including, but not limited to: (i)
          antidiscrimination statutes such as Title VII of the Civil Rights Act
          of 1964, as amended (or similar state or local laws prohibiting
          discrimination because of race, sex, religion, national origin, age
          and the like); (ii) the Fair Labor Standards Act or other federal,
          state or local laws regulating hours of work, wages, overtime and
          other working conditions; (iii) requirements imposed by federal, state
          or local governmental contracts such as those imposed by Executive
          Order 11246; (iv) state laws with respect to tortious employment
          conduct, such as slander, false light, invasion of privacy, negligent

          Safety and Health Act, as amended, as well as any similar state laws,

          best knowledge of American, no proceedings, charges, or complaints are
          threatened under any such laws or regulations and no facts or
          circumstances exist which would give rise to any such proceedings,
          charges, complaints, or claims, whether valid or not.

          after November 6, 1986, (i) American hired such person in compliance
          with the Immigration Reform and Control Act of 1986 and the rules and
          regulations thereunder ("IRCA") and (ii) American has complied with
          all recordkeeping and other regulatory requirements under IRCA.

               (f)  American has not incurred any liability or obligation under
          the Worker Adjustment and Retraining Notification Act or similar state
          laws. American has not laid off more than ten percent (10%) of its
          employees at any single site of employment in any ninety (90) day
          period during the twelve (12) month period ending as of the Closing
          Date. It shall be the obligation of American to provide any notice
          required by said Act by reason of the provisions, execution or
          operation of this Agreement.

               (g)  To the best of American's knowledge, American is in or will
          take all steps necessary for full compliance with the provisions of
          Americans with Disabilities Act (the "ADA"). American acknowledges and
          agrees that it has the obligation to ensure that the facilities
          located on the Immovable Property are in full compliance with the ADA
          and that it will make all modifications to existing facilities
          required for such compliance.

               3.18  Personnel.

               (a)   American has provided AA with (i) the name and current
          annual salary (or rate, if an hourly employee) and other compensation
          (including, without limitation, normal bonus, profit sharing and other
          compensation) now payable by American to each employee, (ii) any
          increase to become effective after the date of this Agreement in the
          total compensation or rate of total compensation payable by American
          to each such person, (iii) all presently outstanding loans and
          advances (other than routine travel advances to be repaid or formally
          accounted for within sixty (60) days) made by American to, or made to
          American by, any director, officer or employee, (iv) all other
          transactions between American and any director, officer or employee of
          American since December 31, 1996 , and (v) all accrued but unpaid
          vacation pay and any other compensation owing to any officer or
          employee which is not disclosed on the Financial Statements. Full
          payment has been made of all compensation and other employee benefit
          amounts which American was required to have paid to each employee
          (including all accrued vacation pay) on or prior to the Closing Date
          (excluding any amounts not yet due).

               (b)  American's relationship with its respective employees is
          good and American has no knowledge of any facts which would indicate
          that American's employees will not continue in its employ on a basis
          acceptable to AA following the Closing.

               3.19 No Breach.

               (a)  Each permit, contract, agreement, deed of trust, lease,
          policy, license, plan, commitment, arrangement, and understanding
          (whether evidenced by a written document or otherwise) referred to in
          this Agreement or in any Schedule or Exhibit hereto, under which
          American has any right, interest, or obligation (i) is in full force
          and effect and (ii) is not subject to any threatened amendment,
          cancellation, or outstanding dispute.

               (b)  American is not in breach of, and there does not exist any
          default or event (including the execution and delivery of this
          Agreement and the consummation of the transactions contemplated
          hereby) which, with the giving of notice or the lapse of time or both,
          would become a breach or default, and there is no basis for any valid
          claim of a default in any respect with regard to any contracts or
          agreements which may be affected by the execution of this Agreement,
          and American has used its best efforts to secure the consents (where
          such consents are necessary) of the other parties to any agreements
          affected hereby, to the consummation of the transactions contemplated
          by this Agreement.

               3.20 Consents, Permits, Etc. No consent, approval, governmental
          filing, authorization, or permit from any person or entity is
          necessary to the consummation of the transactions contemplated by this
          Agreement.

               3.21 Litigation. There is no litigation, proceeding, arbitration,
          administrative or other proceeding or audit, inquiry or investigation
          pending, or controversy (an "Action") pending or threatened by or
          against, or involving American or any directors, officers, or
          employees thereof in their capacity as such or that question or
          challenge the validity of this Agreement, or any action taken or to be
          taken by American pursuant to this Agreement or in connection with the
          transactions contemplated hereby, and to the knowledge of American,
          there is no valid basis for any such Action. No such Action would, if
          adversely decided, have a material adverse effect on the Business
          taken as a whole or, after the Closing Date, on the ability of AA to
          conduct the Business.

               3.22 Compliance With Applicable Law; Adverse Restrictions. The
          operations of American are being conducted in material compliance with
          (a) all applicable permits, orders, writs, injunctions, judgments,
          decrees, or awards of all courts and governmental and regulatory
          authorities, and (b) to the knowledge of American, all laws (statutory
          or otherwise), ordinances, rules, regulations, bylaws, and codes of
          all governmental and regulatory authorities, whether federal, state,
          or local (individually, a "Law" and collectively, "Laws") that are
          applicable to the Assets or the Business (including, without
          limitation, those related to public or occupational safety, pollution
          and protection of the environment, and hazardous or other waste
          disposal). American has not received any written notification of any
          asserted present failure to comply with any Law, except for failures
          that in the aggregate are not and were not material to the conduct of
          the Business as a whole and which American has taken steps to correct
          or contest in good faith.

               3.23 Assets Necessary to Business. As a result of the
          transactions effected hereby and those transactions effected pursuant
          to the Intangible Asset Purchase Agreement, AA (a) will have title to,
          or a valid leasehold interest in, all tangible and intangible assets
          and properties relating to the Business; (b) will possess valid
          consents, authorizations, approvals, and permits relating to the
          Business; and (c) will be party to all agreements, in each case
          necessary to permit AA to continue to carry on the Business
          substantially as currently conducted, specifically including without
          limitation any required consents, authorizations, approvals or permits
          of the FAA relating to the Business.

               3.24 Customers and Suppliers.

               (a)  Since January 1, 1997, there has not been any adverse change
          in the business relationship of American with any customer,
          distributor, or supplier that is material to the business or financial
          condition of the Business taken as a whole. To the knowledge of
          American, no customer or supplier of American will cease to do
          business with the Business after the consummation of the transactions
          contemplated hereby, which cessation would have a material adverse
          effect on the business, operations or financial condition of the
          Business. American has not experienced any difficulties in obtaining
          any inventory, supplies, equipment or other items necessary to the
          operation of its business, and, to the knowledge of American, no such
          shortage of supply of inventory, supplies, equipment or other items is
          threatened or pending. American is not required to provide any bonding
          or other financial security arrangements in any material amount in
          connection with any transactions with any of its customers or
          suppliers.

               (b)  Neither American, nor, to the best of American's knowledge,
          any shareholder, officer, director or employee of American, nor any
          spouse or child of any of them, has any direct or indirect interest in
          any competitor, supplier or customer of American or in any person from
          whom or to whom American leases any real or personal property, or in
          any other person with whom American is doing business.

               3.25 Governmental Approvals and Consents. No approval,
          authorization, consent, or other order or action by American or AA
          before any court, administrative agency, or other governmental
          authority is required for the execution and delivery by American of
          this Agreement or the consummation by American of the transactions
          contemplated hereby.

          or manner that violates or requires further investigation or
          remediation under Environmental Requirements; (iii) the Subject
          Property is free of Hazardous Substances as of the date of this
          Agreement; (iv) there is no pending or threatened litigation or

          Property involving Hazardous Substances or Environmental Requirements;

          fees and expenses of counsel employed by any Indemnitee; provided,
          however, that the Indemnitors shall not be liable for the fees or
          expenses of more than one counsel employed by any Indemnitee in any
          jurisdiction for all Indemnitees. If the Indemnitees assume the

          Indemnitors upon the Indemnitors' reasonable request for such
          consultation from time to time with respect to such suit, action, or
          proceeding and the Indemnitees shall not, without the Indemnitors'
          consent, which consent shall not be unreasonably withheld, settle or
          compromise any such suit, action. or claim. Whether or not the
          Indemnitors choose to defend or prosecute any claim, all of the
          parties hereto shall cooperate in the defense or prosecution thereof.

               (b)  No investigation by any Indemnitee or Indemnitee Affiliate
          prior to the Closing Date shall relieve any Indemnitor of any
          liability hereunder.

               5.4  Cooperation on Tax Matters. American and AA shall cooperate
          fully, as and to the extent reasonably requested by the other party,
          in connection with any audit, litigation, or other proceeding with
          respect to Taxes. Such cooperation shall include the retention and
          (upon the other party's request) the provision of records and
          information which are reasonably relevant to any such audit,
          litigation, or other proceeding and making employees available on a
          mutually convenient basis to provide additional information and
          explanation of any material provided hereunder. AA and American agree
          (a) to retain all books and records which are relevant to the
          determination of the Tax liabilities pertinent to the Assets relating
          to any Pre-Closing Tax Period until the expiration of the applicable
          statute of limitations and to abide by all record retention agreements
          entered into with any Taxing Authority, and (b) to give the other
          party reasonable written notice prior to destroying or discarding any
          such books and records and, if the other party so requests, AA or
          American, as the case may be, shall allow the other party to take
          possession of such books and records.

               6.2  Waiver of Compliance; Consents. Any failure of a party to
          comply with any obligation, covenant, agreement, or condition herein
          may be waived by the other party; provided, however, that any such
          waiver may be made only by a written Instrument signed by the party
          granting such waiver, but such waiver or failure to insist upon strict
          compliance with such obligation, covenant, agreement, or condition
          shall not operate as a waiver of, or estoppel with respect to, any
          subsequent or other failure. Whenever this Agreement requires or
          permits consent by or on behalf of any party hereto, such consent
          shall be given in writing in a manner consistent with the requirements
          for a waiver of compliance as set forth in this Section 6.2, with
          appropriate notice in accordance with Section 6.9 of this Agreement.

          and their respective successors and permitted assigns. Any party may
          assign any of its rights hereunder, but no such assignment shall
          relieve it of its obligations hereunder. Nothing in this Agreement,
          expressed or implied, is intended or shall be construed to confer upon
          any person other than the parties, any successors and permitted
          assigns, any rights, remedy, or claim under or by reason of this
          Agreement or any provisions herein contained.

          transactions contemplated by this Agreement shall be consummated, all
          fees and expenses (including all fees of counsel, actuaries,
          accountants and other experts) incurred by any party in connection
          with the negotiation and execution of this Agreement shall be borne by
          such party.

               6.5  Further Assurances. From time to time, at the request of
          American or AA and without further consideration, each party, at its
          own expense, will execute and deliver such other documents, and take
          such other action, as American or AA may reasonably request in order
          to consummate more effectively the transactions contemplated hereby
          and to vest in AA good and marketable title to the Assets. American

          the account of AA any items of Assets and to institute and prosecute
          all proceedings that AA may in its reasonable discretion deem proper
          in order to assert or enforce any right, title, or interest in, to, or
          under the Assets, and to defend or compromise any and all action,
          suits, or proceedings in respect of the Assets. AA shall be entitled
          to retain for its own account any amounts collected pursuant to the
          foregoing powers, including any amounts payable as interest in respect
          thereof.

               6.6  Governing Law. This Agreement shall be governed by and
          construed in accordance with the laws of the State of Louisiana
          (without regard to its conflicts of law doctrines).

               6.7  Counterparts. This Agreement may be executed in two or more
          counterparts, each of which shall be deemed an original, but all of
          which together shall constitute one and the same 


                                      22

          instrument and shall become a binding Agreement when one or more of
          the counterparts have been signed by each of the parties and delivered
          to the other party.

               6.8  Publicity. Neither of the parties will make any disclosure
          of the transactions contemplated by this Agreement, or any discussions
          in connection therewith, without the prior written consent of each of
          the other parties. The preceding sentence shall not apply to any
          disclosure required to be made by Law or the regulations of any stock
          exchange(s) as reasonably determined by counsel to the party
          determining that such disclosure is required, except that such party,
          whenever practicable, shall be required to consult with the other
          party concerning the timing and content of such disclosure before
          making it.

               6.9  Notices. All notices and other communications hereunder

               6.10 Specific Performance. Each of the parties acknowledge that
          money damages would not be a sufficient remedy for any breach of this

               In consideration of the receipt of the Purchase Price and the

          and non-assessable; and 900 shares are owned by David A. Jeansonne and

          liens, encumbrances, pledges, adverse claims or defects in title.
          There are no outstanding warrants, options, rights, calls or other
          commitments of any nature relating to any share of capital stock of
          the Seller, and there are no outstanding securities or debt
          obligations of the Seller convertible into shares of capital stock of
          the Seller.

               3.2  Organization.

               (a)  The Seller is a corporation duly organized, validly
          existing, and in good standing under the laws of the State of

               (b)  The copy of the Articles of Incorporation and all amendments
          thereto of the Seller, as certified by the Secretary of State of the

          as certified by its Secretary and delivered to the Purchaser, are
          true, complete, and correct copies of the respective Articles of
          Incorporation and Bylaws, as amended and currently in effect, of the
          Seller.

               3.3  Qualification. The Seller is licensed or qualified to do
          business as a foreign corporation and is in good standing in the
          jurisdictions in which it conducts its business (except where the
          failure to so qualify would not have a material adverse effect on the
          business or financial condition of the Business taken as a whole) (the
          "Material Jurisdictions"). There are no such Material Jurisdictions.

               3.4  Authority. The Seller has the corporate power and authority

          Seller of this Agreement and the consummation of the transactions
          contemplated hereby have been duly authorized by the Board of
          Directors and shareholders of the Seller; no other corporate
          proceedings on the part of the Seller or any other person or entity,
          whether pursuant to the Articles of Incorporation or Bylaws of the
          Seller or by law or otherwise, are necessary to authorize the Seller
          to enter into this Agreement, or to consummate the transactions
          contemplated hereby; and this Agreement is the legal, valid, and
          binding obligation of the Seller (and Jeansonne, as the case may be).

          and Jeansonne, enforceable against both the Seller and Jeansonne in

          affecting creditors' rights generally, (ii) the remedy of specific
          performance and injunctive relief are subject to certain equitable
          defenses and to the discretion of the court before which any

          indemnification hereunder may be limited under applicable securities
          laws.

          authorities, whether federal, state, or local, to which the Seller or
          any of its properties or assets are subject;

               (c)  Violates or will violate, or conflicts with or will conflict
          with, any provision of, or constitutes a default under, the Articles

               (d)  (i) violates or breaches or constitutes a default (or an
          event that, with notice or lapse of time or both, would constitute a
          default) under, or give rise to a right to terminate, any mortgage,
          contract, agreement, deed of trust, license, lease, or other
          instrument, arrangement, commitment, obligation, understanding, or
          restriction of any kind to which the Seller is a party or by which its
          properties may be bound, or (ii) will cause, or give any person
          grounds to cause, to be accelerated (with notice or lapse of time or
          both) the maturity of, or will increase, any liability or obligation
          of the Seller.

          Assets are owned by the Purchaser free and clear of all Encumbrances,

          and complete. Each of the Leases is transferable, and all of the
          Seller's rights under any such Leases are hereby transferred to the
          Purchaser, free and clear of all Encumbrances.

               (b)  Each of the Leases is in full force and effect in accordance
          with its terms, no Lease has been modified or amended in writing, and

          default with respect to a Lease.

               3.8  Patents, Trademarks, and Similar Rights.

               (a)  (i)    American has the sole and exclusive right to use the
          Intangible Property (as defined in Schedule 1.1 of this Agreement),
          and the consummation of the transactions contemplated by this
          Agreement and the Intangible Asset Purchase Agreement will not alter

          the Business;

                    (ii)   American has the right to use all Intangible Property
          which is currently used by the Seller in connection with the Business

          Agreement will not alter or impair any such rights and will result in
          the Purchaser having the right to use all such Intangible Property to
          the same extent it is currently used in the Business;

                    (iii)  No claims have been asserted by any person or entity
          for the use of any such Intangible Property or challenging or
          questioning the validity or effectiveness of any such license or

          such claim;

                    (iv)   To the knowledge of the Seller, the use of such
          Intangible Property by the Seller does not infringe on the rights of
          any person or entity and no proceedings have been instituted, are
          pending, or, to the best of the Seller's knowledge, have been
          threatened that challenge the rights of the Seller in respect thereof;
          and

                                       5
<PAGE>
 
                    (v)    None of the Seller's Intangible Property rights, to
          the best of the Seller's knowledge, are being infringed by the
          products, activities, operations, trade names, trademarks, service
          marks, trade dress rights or copyrights of any other person or persons
          and none are subject to any outstanding order, judgment, decree,
          stipulation or agreement restricting the use thereof.

               3.9  Personnel. The Seller's relationship with its respective
          employees is good and the Seller has no knowledge of any facts which

          the knowledge of the Seller, no customer or supplier of the Seller
          will cease to do business with the Business after the consummation of
          the transactions contemplated hereby, which cessation would have a
          material adverse effect on the business, operations or financial
          condition of the Business. The Seller has not experienced any
          difficulties in obtaining any inventory, supplies, equipment or other
          items necessary to the operation of its business, and, to the
          knowledge of the Seller, no such shortage of supply of inventory,
          supplies, equipment or other items is threatened or pending.

               3.11 No Breach. The Seller is not in breach of, and there does
          not exist any default or event (including the execution and delivery
          of this Agreement and the consummation of the transactions
          contemplated hereby) which, with the giving of notice or the lapse of
          time or both, would become a breach or default, and there is no basis
          for any valid claim of a default in any respect with regard to any
          contracts or agreements which may be affected by the execution of this
          Agreement, and the Seller has used its best efforts to secure the
          consents (where such consents are necessary) of the other parties to
          any agreements affected hereby, to the consummation of the
          transactions contemplated by this Agreement.

               3.12 Consents, Permits, Etc. No consent, approval, governmental
          filing, authorization, or Permit from any person or entity, including
          any court, administrative agency, or other governmental authority, is
          necessary to the consummation of the transactions contemplated by this
          Agreement, except for the approval of the Federal Aviation
          Administration ("FAA") of the transfer of the Certificate as defined
          in Schedule 1.1 of this Agreement.

               3.13 Assets Necessary to Business. As a result of the
          transactions effected hereby and the transactions effected pursuant to
          the Exchange Agreement, dated as of even date herewith, between the
          Purchaser, the Seller and Omni, the Purchaser (a) will have title to,
          or a valid leasehold interest in, all assets and properties relating
          to the Business; (b) will possess valid consents, authorizations,
          approvals, and Permits relating to the Business; and (c) will be party
          to all agreements, in each case necessary to permit the Purchaser to
          continue to carry on the Business substantially as currently
          conducted, specifically including without limitation any required
          consents, authorizations, approvals or Permits of the FAA relating to
          the Business.

                     COVENANTS; REPRESENTATIONS; INDEMNIFICATION

               4.1  Consents, Permits, Etc.

               (a)  The Seller (i) has maintained in full force and effect and
          renewed, when required, all Permits, and (ii) has obtained all
          consents, approvals, governmental filings, authorizations, and Permits
          necessary to (A) the consummation of the transactions contemplated by
          this Agreement, and (B) the continued conduct of the Business by the
          Purchaser after the Closing Date as it is currently conducted by the
          Seller, and delivers herewith to the Purchaser copies of each such
          consent, approval, governmental filing, authorization, and Permit,
          including any required required consents, authorizations, approvals or
          Permits of the FAA relating to the Business.

               (b)  In the event and to the extent that any of the contracts,
          leases, agreements, Permits, plans, commitments, purchase orders, or
          other binding arrangements relating to the Assets (in this Section
          4.1(b) called "Commitments") cannot be assumed by or assigned to the
          Purchaser (pursuant to the Exchange Agreement) or sold to the
          Purchaser (pursuant to this Agreement) without the consent of another
          party, and such consent has not been obtained as of the Closing Date,
          the Seller and the Purchaser each agrees to cooperate with the other
          in any reasonable arrangement designed to enable the Seller to perform
          its obligations under, and to provide for the Purchaser the benefits
          of, any such Commitments as of the Effective Date, including
          enforcement at any cost, and for the account of the Purchaser, of any
          and all rights of the Seller against the other party thereto arising
          out of the breach or cancellation thereof by such other party or
          otherwise. The Seller will promptly pay to the Purchaser when received
          all monies received by the Seller under any such Commitments.

               (c)  In the event and to the extent that any of the contracts,
          leases, agreements, Permits, plans, commitments, purchase orders, or
          other binding arrangements relating to the Assets (in this Section
          4.1(c) called "Licenses") cannot be assumed by or assigned to the
          Purchaser (pursuant to the Exchange Agreement) or sold to the
          Purchaser (pursuant to this Agreement) without the consent of a court,
          administrative agency, or other governmental authority, specifically
          including without limitation the FAA, and such consent has not been
          obtained as of the Closing Date, the Seller and the Purchaser each
          agrees to cooperate with the other in any reasonable arrangement
          designed to enable the Seller to continue to operate and perform
          under, and to provide for the Purchaser the benefits of, any such
          Licenses and the operations thereunder as of the Effective Date, at no
          cost to the Purchaser and for the account of the Purchaser, until such
          time as the consent to the transfer of such Licenses to the Purchaser
          and the Purchaser's right to operate thereunder can be obtained. The
          Seller will promptly pay to the Purchaser when received all monies
          received by the Seller from its operations under any such Licenses.

               (a)  The representations and warranties of the parties hereto
          contained herein or in any certificate or other writing delivered
          pursuant hereto or in connection herewith shall survive the Closing
          Date and shall extend without limit as to time. The covenants and
          agreements of the parties hereto contained herein or in any
          certificate or other writing delivered pursuant hereto or in
          connection herewith shall survive the Closing Date in accordance with
          their terms.

               (b)  The Seller and Jeansonne and their successors and assigns
          (each an "Indemnitor"), jointly and severally, hereby agree to
          indemnify each the Purchaser and Omni against and agree to hold it
          harmless from any and all damage, loss, liability, and expense
          (including, without limitation, reasonable expenses of investigation
          and attorney's fees and expenses in connection with any action, suit,
          proceeding, claim, investigation, or other loss) (a "Loss") incurred
          or suffered by the Purchaser or Omni arising out of or relating to:

                    (i)    Any breach of any covenant or agreement or any
          inaccuracy or omission in any representation or warranty made by the
          Seller or Jeansonne pursuant to this Agreement;

                    (ii)   Claims by third parties in connection with the sale
          by the Seller of the Assets to the Purchaser; and

                                      SECTION 5
                               MISCELLANEOUS PROVISIONS

               5.1  Amendment and Modification. This Agreement may be amended,
          modified, or supplemented only by written agreement of the parties
          hereto.

               5.2  Waiver of Compliance; Consents. Any failure of a party to
          comply with any obligation, covenant, agreement, or condition herein
          may be waived by the other party; provided, however, that any such
          waiver may be made only by a written Instrument signed by the party
          granting such waiver, but such waiver or failure to insist upon strict
          compliance with such obligation, covenant, agreement, or condition
          shall not operate as a waiver of, or estoppel with respect to, any
          subsequent or other failure. Whenever this Agreement requires or
          permits consent by or on behalf of any party hereto, such consent
          shall be given in writing in a manner consistent with the requirements
          for a waiver of compliance as set forth in this Section 6.2, with
          appropriate notice in accordance with Section 5.9 of this Agreement.

               5.3  Assignment. This Agreement and all of the provisions hereof
          shall be binding upon and inure to the benefit of the parties hereto
          and their respective successors and permitted assigns. Any party may
          assign any of its rights hereunder, but no such assignment shall
          relieve it of its obligations hereunder. Nothing in this Agreement,
          expressed or implied, is intended or shall be construed to confer upon
          any person other than the parties, any successors and permitted
          assigns, 

                                       8
<PAGE>
 
          any rights, remedy, or claim under or by reason of this Agreement or
          any provisions herein contained.

               5.4  Expenses, Transfer Taxes, Etc. Whether or not the
          transactions contemplated by this Agreement shall be consummated, all
          fees and expenses (including all fees of counsel, actuaries,
          accountants and other experts) incurred by any party in connection
          with the negotiation and execution of this Agreement shall be borne by
          such party.

               5.5  Further Assurances. From time to time, at the request of the
          Seller or the Purchaser and without further consideration, each party,
          at its own expense, will execute and deliver such other documents, and
          take such other action, as the Seller or the Purchaser may reasonably
          request in order to consummate more effectively the transactions
          contemplated hereby and to vest in the Purchaser good and marketable
          title to the Assets. The Seller hereby constitutes and appoints,
          effective as of the Effective Date, the Purchaser and its successors
          and permitted assigns as the true and lawful attorney of the Seller
          with full power of substitution in the name of the Purchaser or in the
          name of the Seller, but for the benefit of the Purchaser, to collect
          for the account of the Purchaser any items of Assets and to institute
          and prosecute all proceedings that the Purchaser may in its reasonable
          discretion deem proper in order to assert or enforce any right, title,
          or interest in, to, or under the Assets, and to defend or compromise
          any and all action, suits, or proceedings in respect of the Assets.
          The Purchaser shall be entitled to retain for its own account any
          amounts collected pursuant to the foregoing powers, including any
          amounts payable as interest in respect thereof.

               5.6  Governing Law. This Agreement shall be governed by and
          construed in accordance with the laws of the State of Louisiana
          (without regard to its conflicts of law doctrines).

               5.7  Counterparts. This Agreement may be executed in two or more
          counterparts, each of which shall be deemed an original, but all of
          which together shall constitute one and the same instrument and shall
          become a binding Agreement when one or more of the counterparts have
          been signed by each of the parties and delivered to the other party.

               5.8  Publicity. Neither of the parties will make any disclosure
          of the transactions contemplated by this Agreement, or any discussions
          in connection therewith, without the prior written consent of each of
          the other parties. The preceding sentence shall not apply to any
          disclosure required to be made by Law or the regulations of any stock
          exchange(s) as reasonably determined by counsel to the party
          determining that such disclosure is required, except that such party,
          whenever practicable, shall be required to consult with the other
          party concerning the timing and content of such disclosure before
          making it.

               5.9  Notices. All notices and other communications hereunder
          shall be in writing and shall be deemed to have been duly given if
          delivered by hand or mailed by registered or certified mail (return
          receipt requested) to the parties at the following addresses (or at
          such other address for a party as shall be specified by like notice):

               5.10 Specific Performance. Each of the parties acknowledge that
          money damages would not be a sufficient remedy for any breach of this

          this Agreement shall, for any reason, be held to be invalid, illegal,
          or unenforceable in any respect, such invalidity, illegality, or
          unenforceability shall not affect any other provision of this
          Agreement, but this Agreement shall be construed as if such invalid,
          illegal, or unenforceable provision had never been contained herein.

               5.14 Schedules and Exhibits. All Schedules and Exhibits attached
          hereto are hereby incorporated in and made a part as if set forth in

               (a)  The Seller is a corporation duly organized, validly
          existing, and in good standing under the laws of the State of Texas,
          with the corporate power and authority to own, lease, and operate its
          properties and to carry on its business as now being conducted.

               (b)  The copy of the Articles of Incorporation and all amendments
          thereto of the Seller, as certified by the Secretary of State of the
          State of Texas, and the Bylaws, as amended to date, of the Seller, as
          certified by its Secretary and delivered to the Purchaser, are true,
          complete, and correct copies of the respective Articles of
          Incorporation and Bylaws, as amended and currently in effect, of the
          Seller.

               3.3  Qualification. The Seller is licensed or qualified to do
          business as a foreign corporation and is in good standing in the
          jurisdictions in which it conducts its business (except where the
          failure to so qualify would not have a material adverse effect on the
          business or financial condition of the Business taken as a whole) (the
          "Material Jurisdictions").

               3.4  Authority. The Seller has the corporate power and authority
          to execute and deliver this Agreement and to consummate the

          Seller of this Agreement and the consummation of the transactions
          contemplated hereby have been duly authorized by the Board of
          Directors and shareholders of the Seller; no other corporate
          proceedings on the part of the Seller or any other person or entity,
          whether pursuant to the Articles of Incorporation or Bylaws of the
          Seller or by law or otherwise, are necessary to authorize the Seller
          to enter into this Agreement, or to consummate the transactions
          contemplated hereby. This Agreement has been duly executed and
          delivered by the Seller and Krater and constitutes the valid and
          binding obligation of the Seller and Krater, enforceable against each
          of them in accordance with its terms, except that (i) such enforcement
          may be subject to bankruptcy, insolvency, moratorium or similar laws
          affecting creditors' rights generally, (ii) the remedy of specific
          performance and injunctive relief are subject to certain equitable
          defenses and to the discretion of the court before which any
          proceedings therefor may be brought, and (iii) rights to
          indemnification hereunder may be limited under applicable laws.

               3.5  No Violations. Neither the execution or delivery of this
          Agreement nor the consummation of the transactions contemplated
          hereby:

               (a)  Requires any filing or registration with, or consent,
          authorization, approval, or Permit of, any governmental or regulatory
          authority on the part of the Seller;

               (b)  Violates or will violate (i) any order, writ, injunction,
          judgment, decree, or award of any court or governmental or regulatory
          authority or (ii) to the knowledge of the Seller, violates or will
          violate any "Law," as defined in Section 3.22 of this Agreement, of
          any governmental or regulatory authority to which the Seller or any of
          its properties or assets are subject;

               (c)  Violates or will violate, or conflicts with or will conflict
          with, any provision of, or constitutes a default under, the Articles
          of Incorporation or Bylaws of the Seller; or

                                       5
<PAGE>
 
               (d)  (i) violates or breaches or constitutes a default (or an
          event that, with notice or lapse of time or both, would constitute a
          default) under, or give rise to a right to terminate, any mortgage,
          contract, agreement, deed of trust, license, lease, or other
          instrument, arrangement, commitment, obligation, understanding, or
          restriction of any kind to which the Seller is a party or by which its
          properties may be bound, or (ii) will cause, or give any person
          grounds to cause, to be accelerated (with notice or lapse of time or
          both) the maturity of, or will increase, any liability or obligation
          of the Seller.

               3.6  Financial Statements. The Seller has heretofore delivered to
          the Purchaser its balance sheet as of August 4, 1997 (the "Balance
          Sheet"), and the related statement of operations for the period from
          January 1, 1997 through August 4, 1997, together with its balance
          sheet as of December 31, 1996 and the related statement of operations
          for the year then ended. The financial statements referred to in the
          preceding sentence are hereinafter collectively referred to as the
          "Financial Statements." Each of the Financial Statements was prepared
          from the books and records of the Seller, in conformity with generally
          accepted accounting principles consistently applied, and fairly
          present the financial condition and results of operations of the
          Business for the periods and as of the dates stated therein. Except to
          the extent reflected in the Financial Statements, the Seller has no
          liabilities or obligations required to be reflected in the Financial
          Statements (or the notes thereto) in accordance with generally
          accepted accounting principles other than current liabilities incurred
          in the ordinary course of business, consistent with past practice,
          subsequent to August 4, 1997.

               3.7  Absence of Certain Changes or Events. Since August 4, 1997
          (the "Balance Sheet Date"), the Seller has operated the Business in
          the ordinary course consistent with past practice, and neither the
          Seller nor the Business has:

               (a)  Suffered any material adverse change in its business or any
          event or condition of any character, which individually or in the
          aggregate, has had or might reasonably be expected to have a material
          adverse effect on the business or financial condition of the Business
          taken as a whole;

               (b)  Incurred any obligations or liabilities (absolute, accrued,

          commitments or agreements other than in the ordinary course of
          business and consistent with past practice;

               (c)  Paid, discharged, or satisfied any claims, obligations, or
          liabilities (absolute, accrued, contingent, or otherwise), except the
          payment, discharge, or satisfaction in the ordinary course of business
          and consistent with past practice of any claims, obligations, and
          liabilities (i) which are reflected or reserved against in the
          Financial Statements or (ii) which were incurred in the ordinary
          course of business and consistent with past practice since the Balance
          Sheet Date;

               (d)  Permitted or allowed any of its properties or assets,
          whether tangible or intangible, to be subjected to any Encumbrances or
          other liabilities and obligations;

          withholding, real and personal property tax returns known by Seller to

          any Tax or any proposed transaction pending before any Taxing
          Authority (as defined in Section 5.2 of this Agreement).

               (c)  Seller is not aware of any state of facts that could
          reasonably be expected to give rise to any claim, audit, action, suit,
          proceeding, or investigation with respect to any Tax or assessment for
          which the Purchaser could be liable.

               (d)  To the best of Seller or Krater's knowledge, no Tax or

          government or subdivision or agency thereof, and including any
          interest, penalties or additions attributable thereto.

               (e)  Purchaser is liable for all property taxes relating to the
          Assets for the entire calendar years 1997. There will be nor proration
          between Purchaser and Seller for said 1997 taxes.

               (f)  To the extent that any or all of the transactions covered by
          this Agreement (including the Sale of Assets) are subject to transfer,
          sales, or use taxes, such taxes will be paid by Purchaser, along with
          any interest, penalties, or other charges for any delay in payment.

               3.9  Condition of Facilities. The facilities included in the
          Assets, including equipment, furniture, vehicles and other tangible
          personal property, are in good operating condition and repair,
          ordinary wear and tear excepted and are in adequate working order for
          the continued conduct of the Business as it is currently conducted and
          Seller has no knowledge of any condition or defect, not disclosed
          herein, in any of the Assets which would materially affect the fair
          market value, use or operation of the Business, such as to have a
          material adverse effect on the Business or its operations.

               3.10 Title to Properties; Encumbrances.

               (a)  To the best of its knowledge, seller has good and marketable

          Seller has the sole and exclusive right to use the Intangible Property
          referred to in Section 1.1(a)(ii), and the consummation of the
          transactions contemplated by this Agreement should not alter or impair
          any such rights and should result in the Purchaser having the sole and
          exclusive right to use all such Intangible Property used in the
          Business (Purchaser, however, does not gain any rights in Seller's
          name or any mark or name which Seller is or may be known);

                    (ii)   The Seller has the right to use all Intangible
          Property which is currently used by the Seller in connection with the
          Business either as provided in clause (i) above or as licensed or
          authorized by others, and, upon information and belief, the
          consummation of the transactions contemplated by this Agreement will
          not alter or impair any such rights and will result in the Purchaser
          having the right to use all such Intangible Property to the same
          extent it is currently used in the Business;

                    (iii)  To the best of Seller's knowledge, no claims have
          been asserted by any person or entity for the use of any such

          knowledge of any valid basis for any such claim; and

                    (iv)   To the best of Seller's knowledge, the use of such
          Intangible Property by the Seller does not infringe on the rights of
          any person or entity and no proceedings have been instituted, are
          pending, or, to the best of Sellers' knowledge, threatened that
          challenge the rights of the Seller in respect thereof.

                                       9
<PAGE>
 
                    (v)    None of Seller's Intangible Property rights, to the
          best of Seller's knowledge, are being infringed by the products,

          dress rights or copyrights of any other person or persons and none are

          periods up to and including the Closing Date have been paid, and no
          notice of cancellation or termination has been received with respect
          to any such policy. Such policies are in such amounts and insure
          against such losses and risks and provide such coverage as, in the
          opinion of the Seller, is adequate to protect the Business as it is
          currently conducted.

               3.14 No Benefit Plans; Absence of PBGC Lien. Neither the Seller
          nor any Affiliate (as defined in Section 5.2 of this Agreement)
          maintains any "employee benefit plan" (as defined in Section 3(3) of
          the Employee Retirement Income Security Act of 1974, as amended, and

          employee, (iv) all other transactions between the Seller and any
          director, officer or employee of the Seller since December 31, 1996 ,

          owing to any officer or employee which is not disclosed on the

          default or event (including the execution and delivery of this
          Agreement and the consummation of the transactions contemplated
          hereby) which, with the giving of notice or the lapse of time or both,
          would become a breach or default, and there is no basis for any valid
          claim of a default in any respect with regard to any contracts or
          agreements which may be affected by the execution of this Agreement,
          and the Seller has used its best efforts to secure the consents (where
          such consents are necessary) of the other parties to any agreements
          affected hereby, to the consummation of the transactions contemplated
          by this Agreement.


               3.19 Litigation. There is no litigation, proceeding, arbitration,
          administrative or other proceeding or audit, inquiry or investigation
          pending, or controversy (an "Action") pending or threatened by or

          employees thereof in their capacity as such or that question or

<PAGE>

          connection with the transactions contemplated hereby, and to the
          knowledge of the Seller, there is no valid basis for any such Action.
          No such Action would, if adversely decided, have a material adverse
          effect on the Business taken as a whole or, after the Closing Date, on
          the ability of the Purchaser to conduct the Business.

          operations of the Seller are being conducted in material compliance
          with (a) all applicable Permits, orders, writs, injunctions,
          judgments, decrees, or awards of all courts and governmental and
          regulatory authorities, and (b) to the knowledge of the Seller, all
          laws (statutory or otherwise), ordinances, rules, regulations, bylaws,
          and codes of all governmental and regulatory authorities, whether
          federal, state, or local (individually, a "Law" and collectively,
          "Laws") that are applicable to the Assets or the Business (including,
          without limitation, those related to public or occupational safety,
          pollution and protection of the environment, and hazardous or other
          waste disposal). The Seller has not received any written notification
          of any asserted present failure to comply with any Law, except for
          failures that in the aggregate are not and were not material to the
          conduct of the Business as a whole and which the Seller has taken
          steps to correct or contest in good faith.

          transactions effected hereby, the Seller (with respect to Assets owned
          prior to the Closing Date by the Seller) will use its best efforts (a)
          to have title to, or a valid leasehold interest in, all tangible and
          intangible assets and properties relating to the Business; (b) to
          possess valid consents, authorizations, approvals, and Permits
          relating to the Business; and (c) to be party to all agreements
          necessary to permit the Purchaser to continue the Business
          substantially as currently conducted.

               3.22 Customers and Suppliers.

               (a)  Since January 1, 1997, there has not been any adverse change
          in the business relationship of the Seller with any customer,
          distributor, or supplier that is material to the business or financial
          condition of the Business taken as a whole. To the knowledge of the
          Seller, no customer of supplier of the Seller will cease to do
          business with the Business after the consummation of the transactions
          contemplated hereby, which cessation would have a material adverse
          effect on the business, operations or financial condition of the
          Business. Seller has not experienced any difficulties in obtaining any
          inventory, supplies, equipment or other items necessary to the
          operation of its business, and, to the knowledge of the Seller, no
          such shortage of supply of inventory, supplies, equipment or other
          items is threatened or pending. The Seller is not required to provide
          any bonding or other financial security arrangements in any material
          amount in connection with any transactions with any of its customers
          or suppliers.

               (b)  Neither the Seller, nor, to the best of Seller's knowledge,
          any shareholder, officer, director or employee of the Seller, nor any
          spouse or child of any of them, has any direct or indirect interest in
          any competitor, supplier or customer of the Seller or in any person
          from whom or to whom the Seller leases any real or personal property,
          or in any other person with whom the Seller is doing business.

               3.23 Governmental Approvals and Consents. No approval,
          authorization, consent, or other order or action by the Seller or the
          Purchaser before any court, administrative agency, or other
          governmental authority is required for the execution and delivery by
          the Seller of this Agreement or the consummation by the Seller of the
          transactions contemplated hereby.

          Substances as of the date of this Agreement; (iv) there is no pending
          or threatened litigation or administrative investigation or proceeding
          concerning the Subject Property involving Hazardous Substances or
          Environmental Requirements; and (v) there is no ACM (as defined
          below), within the Subject Property, whether friable or non-friable,
          and there are no above-ground or underground storage tank systems
          ("Tank Systems") located at the Subject Property, other than a small,
          skid-mounted tank which carries used motor oil and other skid-mounted
          fuel tanks, all of which are a part of Seller's Wyoming operation and
          all of which are customary in Seller's line of business. With respect
          to any potential adverse environmental problems (as outlined in this
          paragraph) which were caused by someone other than Seller, Seller and
          Krater can only represent that they have no knowledge of the existence
          of any facts, which, to the best of their knowledge, might give rise
          to such problems.

                               COVENANTS OF THE PARTIES

               4.1  Consents, Permits, Etc.

          Purchaser without the consent of another party, and such consent has
          not been obtained as of the Closing Date, the Seller and the Purchaser
          agree to cooperate with the other in any reasonable arrangement
          designed to enable the Seller to perform its obligations under, and to
          provide for the Purchaser the benefits of, any such agreements,
          effective as of the Effective Date.

                                      SECTION 5

          connection herewith shall survive the Closing Date and shall extend
          for a period of two years, and no statute of limitations (including
          the prescription law of Louisiana) shall serve to extend this period

          hereto or in connection herewith shall survive the Closing Date in
          accordance with their terms.

          shall cooperate fully, as and to the extent reasonably requested by

                                      14
<PAGE>
 
          any such audit, litigation, or other proceeding and making employees
          available on a mutually convenient basis to provide additional
          information and explanation of any material provided hereunder. The
          Purchaser and the Seller agree (a) to retain all books and records
          which are relevant to the determination of the Tax liabilities
          pertinent to the Assets relating to any Pre-Closing Tax Period until
          the expiration of the applicable statute of limitations and to abide
          by all record retention agreements entered into with any Taxing
          Authority, and (b) to give the other party reasonable written notice
          prior to destroying or discarding any such books and records and, if
          the other party so requests, the Purchaser or the Seller, as the case
          may be, shall allow the other party to take possession of such books
          and records.

                                      SECTION 6
                              MISCELLANEOUS PROVISIONS

               6.1  Amendment and Modification. This Agreement may be amended,
          modified, or supplemented only by written agreement of the parties
          hereto.

               6.2  Waiver of Compliance; Consents. Any failure of a party to
          comply with any obligation, covenant, agreement, or condition herein
          may be waived by the other party; provided, however, that any such
          waiver may be made only by a written Instrument signed by the party
          granting such waiver, but such waiver or failure to insist upon strict
          compliance with such obligation, covenant, agreement, or condition
          shall not operate as a waiver of, or estoppel with respect to, any
          subsequent or other failure. Whenever this Agreement requires or
          permits consent by or on behalf of any party hereto, such consent
          shall be given in writing in a manner consistent with the requirements
          for a waiver of compliance as set forth in this Section 6.2, with
          appropriate notice in accordance with Section 6.9 of this Agreement.

               6.3  Assignment. This Agreement and all of the provisions hereof
          shall be binding upon and inure to the benefit of the parties hereto.
          No assignment shall be binding unless a written consent is obtained
          from the other party.

               6.4  Expenses, Transfer Taxes, Etc. Whether or not the
          transactions contemplated by this Agreement shall be consummated, all
          fees and expenses (including all fees of counsel, actuaries,
          accountants and other experts) incurred by any party in connection
          with the negotiation and execution of this Agreement shall be borne by
          such party. For example, if a party requests that certain information
          be obtained by a third party (e.g., an appraisal of equipment or
          property), all expenses incurred in gathering such information shall
          be borne by the party requesting the information.

               6.5  Further Assurances. From time to time, at the request of the
          Seller or the Purchaser, each party, at its own expense, will execute
          and deliver such other documents, and take such other action, as the
          Seller or the Purchaser may reasonably request in order to consummate
          more effectively the transactions contemplated hereby and to vest in
          the Purchaser good and marketable title to the Assets. If compliance
          with any such reasonable request requires the other party to incur 


                                      15
<PAGE>
 
          out-of-pocket expenses, such reasonable expenses shall be reimbursed
          by the party making such request. The Seller hereby constitutes and
          appoints, effective as of the Closing Date, the Purchaser and its
          successors and permitted assigns, but for the benefit of the
          Purchaser, to collect for the account of the Purchaser any items of
          Assets (as defined in Section 1, above) and to institute and prosecute
          all proceedings that the Purchaser may in its reasonable discretion
          deem proper in order to assert or enforce any right, title, or
          interest in, to, or under the Assets, and to defend or compromise any
          and all action, suits, or proceedings in respect of the Assets. The
          Purchaser shall be entitled to retain for its own account any amounts
          collected pursuant to the foregoing powers, including any amounts
          payable as interest in respect thereof. Purchaser agrees to hold
          Seller harmless for the result of any such proceeding and to indemnify
          Seller for all costs of litigation (including attorneys' fees) and all
          damage which Seller may incur arising our of such litigation.

               6.6  Governing Law. This Agreement shall be governed by and
          construed in accordance with the laws of the State of Texas (without
          regard to its conflicts of law doctrines).

               6.7  Counterparts. This Agreement may be executed in three or
          more counterparts, each of which shall be deemed an original, but all
          of which together shall constitute one and the same instrument and
          shall become a binding Agreement when one or more of the counterparts
          have been signed by each of the parties and delivered to the other
          party.

               6.8  Publicity. Neither the Seller nor Krater will make any
          disclosure of the Purchase Price contemplated by this Agreement, or
          any discussions in connection therewith, without the prior written
          consent of the Purchaser. The preceding sentence shall not apply to
          any disclosure required to be made by Law or the regulations of any
          stock exchange(s) as reasonably determined by counsel to the party
          determining that such disclosure is required, except that such party,
          whenever practicable, shall be required to consult with the other
          party concerning the timing and content of such disclosure before
          making it.

               6.9  Notices. All notices and other communications hereunder
          shall be in writing and shall be deemed to have been duly given if
          delivered by hand or mailed by registered or certified mail (return
          receipt requested) to the parties at the following addresses (or at
          such other address for a party as shall be specified by like notice):

such public disclosure was made. Such shareholder's notice shall set forth or
include the following:

         1.  as to each person whom the shareholder proposes to nominate for
     election or re-election as a director, (a) the name, age, business address
     and residential address of such person, (b) the principal occupation or
     employment of such person, (c) the class and number of shares of capital
     stock of the Corporation of which such person is the beneficial owner (as
     defined in Rule 13d-3 promulgated under the Securities Exchange Act of
     1934, as amended (the "Exchange "Act")), (d) such person's written consent
     to being named in the proxy statement as a nominee and to serve as a
     director if elected and (e) any other information relating to such person
     that would be required to be disclosed in solicitations of proxies for the
     election of directors, or would be otherwise required, in each case
     pursuant to Regulation 14A promulgated under the Exchange Act; and

         2. as to the shareholder of record giving the notice, (a) the name and
     address of such shareholder and (b) the class and number of shares of
     capital stock of the Corporation of which such shareholder is the
     beneficial owner (as defined in Rule 13d-3 promulgated under the Exchange
     Act). If requested in writing by the Secretary of the Corporation at least
     15 days in advance of the meeting, such shareholder shall disclose to the
     Secretary, within ten days of such request, whether such person is the sole
     beneficial owner of the shares held of record by him, and, if not, the name
     and address of each other person known by the shareholder of record to
     claim or have a beneficial interest in such shares.

At the request of the Board of Directors, any person nominated by the Board of
Directors for election as a director shall furnish to the Secretary of the
Corporation that information required to be set forth in a shareholder's notice
of nomination which pertains to the nominee. If a shareholder seeks to nominate
one or more directors, the Secretary shall appoint two inspectors, who shall not
be affiliated with the Corporation, to determine whether the shareholder has
complied with this Article IV(E). If the inspectors shall determine that the
shareholder has not complied with this Article IV(E), the defective nomination
shall be disregarded and the inspectors shall direct the Chairman of the meeting
to declare at the meeting that such nomination was not made in accordance with
the procedures prescribed by the Articles of Incorporation.

     F.  Directors Elected by Preferred Shareholders.  Notwithstanding anything
in these Articles of Incorporation to the contrary, whenever the holders of any
one or more classes or series of stock having a preference over the Common Stock
as to dividends or upon liquidation shall have the right, voting separately as a
class, to elect one or more directors of the Corporation, the provisions of
these Articles of Incorporation (as they may be duly amended from time to time)
fixing the rights and preferences of such preferred stock shall govern with
respect to the nomination, election, term, removal, vacancies or other related
matters with respect to such directors.

                                    BY-LAWS

     A.  Adoption, Amendment and Repeal.  The By-laws of the Corporation and of
any provision thereof may be adopted only by a majority vote of all directors
who constitute the Board of Directors. The By-laws and any provision thereof may
be amended or repealed only by (1) a majority vote of all directors who
constitute the Board of Directors, or (2) the affirmative vote of the holders of
at least two-thirds of that portion of the Total Voting Power, as defined in
Article VII(C) hereof, voting together as a single class, that is present or
represented at any regular or special meeting of shareholders, the notice of
which meeting of shareholders expressly states that the proposed amendment or
repeal is to be considered at the meeting.

     B.  New Matters.  Any purported amendment to the By-laws which would add
thereto a matter not expressly covered in the By-laws prior to such purported
amendment shall be deemed to constitute the adoption of a By-law provision and
not an amendment to the By-laws.

                                  ARTICLE VI
                          APPLICATION OF CERTAIN LAWS

     The Corporation hereby elects not to be governed by Sections 132, 133 and

and La.R.S. 12:134).

                                  ARTICLE VII
                    SPECIAL SHAREHOLDER VOTING REQUIREMENTS

     A.  Amendments.  Unless approved by vote of a majority of all directors

set forth in Article VIII(E), shareholders may, by the affirmative vote of a
majority of the voting power present or represented at a meeting of
shareholders, adopt any amendment to the Articles of Incorporation that does not
affect any of such articles; provided, that shareholder approval shall not be
required for any amendment authorized by Article III(B).

     B.  Other Corporate Actions.  If a vote of shareholders is required to
authorize an agreement of merger or consolidation of the Corporation, the sale
of all or substantially all of the assets of the Corporation or the voluntary
dissolution of the Corporation, then (1) unless such action has been approved by
vote of a majority of all directors constituting the Board of Directors, such
action may be authorized only by the affirmative vote of eighty percent of the
Total Voting Power of the Corporation and (2) if any such action has been
approved by vote of at least two-thirds of all directors who constitute the

majority of the voting power present or represented at a meeting of
shareholders.

by the Corporation pursuant to La.R.S. 12:75(H), are generally entitled to cast
with respect to the election of directors or, if such term is used with
reference to any other particular matter properly brought before the
shareholders or such other holders for their consideration and vote, means the
total number of such votes that are entitled to be cast with respect to such
matter.

     D.  Foreign Ownership of Common Stock.  (1) For purposes of this paragraph
D, the following terms shall have the meanings specified below:

              "Act" means the Federal Aviation Administration Authorization Act
         of 1994, as amended.

              "Beneficial Ownership," "Beneficially Owned," or "Beneficially
         Own" refers to beneficial ownership as defined in Rule 13d-3 (without
         regard to the 60-day provision in paragraph (d)(1)(i) thereof)
         promulgated by the Securities and Exchange Commission as such rule may
         be amended from time to time.

              "FAA" means the Federal Aviation Administration.

              "Non-Citizen Owned Shares" means any issued and outstanding Voting
         Securities that are owned of record, Beneficially Owned, or otherwise
         controlled by any Person or Persons who are not United States Citizens.

              "Permitted Percentage" means one percent less than the percentage
         of the voting interest in the Corporation that may be owned or
         controlled by Persons who are not United States Citizens without loss,
         under Section 40102(a)(15) of Title 49 of the United States Code or any
         successor or other applicable law or regulation, of the United States
         Citizen status of the Corporation or any Subsidiary.

              "United States Citizen" means any Person who is a Citizen of the
         United States as defined in Section 40102(a)(15) of Title 49 of the

         successor statute or regulation.

                                      -5-
<PAGE>
 
              "Voting Securities" means the Common Stock, any other voting stock
         of the Corporation, and any bonds, debentures or other obligations
         granted voting rights by the Corporation pursuant to La. R.S. 12:75(H).

         (2)  The Corporation holds operating certificates issued by the FAA
     pursuant to the regulations promulgated under the Act, and the Board and
     shareholders deem the retention of the Corporation's rights under such
     certificate to be of material importance to the Corporation. As long as the
     Corporation holds, or the Board deems it desirable for the Corporation to
     hold, its current operating certificates or any other certificate issued by
     the FAA pursuant to the Act and the regulations promulgated thereunder or
     any successor statute or regulation, it shall be the Corporation's policy
     that the number of Non-Citizen Owned Shares shall not exceed the Permitted
     Percentage.

         (3)  If at any time the voting interest of Non-Citizen Owned Shares
     exceeds the Permitted Percentage, then (i) the voting power otherwise
     attributable to each Non-Citizen Owned Share shall be immediately and
     automatically reduced on a pro rata basis (based on the proportion of the
     voting power otherwise attributable to such Non-Citizen Owned Share to the
     total voting power attributable to all Non-Citizen Owned Shares) without
     any further action by the Corporation so that the maximum number of votes
     that may be cast by the holders of all Non-Citizen Owned Shares shall equal
     the Permitted Percentage and (ii) the total voting power of any affected
     class or series of Voting Securities shall also be immediately and
     automatically reduced without any further action by the Corporation by the
     total number of votes by which the voting power of Non-Citizen Owned Shares
     of such class or series was reduced pursuant to clause (i) of this
     subparagraph (3).

         (4)  In determining the citizenship of any Person who Beneficially Owns
     Voting Securities, the Corporation may rely on the Corporation's stock
     transfer records and the citizenship provided by any Person shown as the
     record owner and any Person who the Corporation has reasonable cause to
     believe Beneficially Owns such Voting Securities. The Board may establish
     procedures to monitor the Beneficially Ownership and control of Voting
     Securities, to make any reasonable determination regarding the Beneficial
     Ownership and control of Voting Securities, and to take any actions deemed
     necessary or desirable to ensure that the voting interest of Non-Citizen
     Owned Shares does not exceed the Permitted Percentage. The Board may, but
     unless expressly provided otherwise is not required to, rely on any
     statutes, regulations, policies, procedures, rulings, or determinations of
     the FAA, or any successor governmental authority, in deciding the extent to
     which Voting Securities are Beneficially Owned or controlled by United
     States Citizens.

         (5)  The Corporation may by notice in writing (which may be included in
     a proxy or ballot distributed to the Corporation's shareholders) require
     any Person that is a holder of record of Voting Securities or that the
     Corporation has reasonable cause to believe Beneficially Owns or controls
     Voting Securities to certify in such manner as the Corporation

                                      -6-
<PAGE>
 
     shall deem appropriate (including execution of a proxy or ballot) that, to
     the knowledge of such Person:

              (a)  all Voting Securities owned of record, Beneficially Owned, or
         controlled by such Person are owned and controlled only by United
         States Citizens; or

              (b)  the number and class or series of Non-Citizen Owned Shares
         owned of record, Beneficially Owned, or controlled by such Person are
         as set forth in such certificate.

     The Corporation may require any Person certifying as to the ownership or
     control of Voting Securities in response to clause (a) of this subparagraph
     (5) to provide such further information as the Corporation may reasonably
     request in order to implement the provisions of this paragraph B. If any
     Person fails to provide such certificate or other information, the
     Corporation may presume that all such Voting Securities are Non-Citizen
     Owned Shares.

                                 ARTICLE VIII
                  LIMITATION OF LIABILITY AND INDEMNIFICATION

     A.  Limitation of Liability.  No director or officer of the Corporation
shall be liable to the Corporation or to its shareholders for monetary damages
for breach of his fiduciary duty as a director or officer, provided that the
foregoing provision shall not eliminate or limit the liability of a director or
officer for (1) any breach of his duty of loyalty to the Corporation or its
shareholders; (2) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law; (3) liability for unlawful
distributions of the Corporation's assets to, or redemptions or repurchases of
the Corporation's shares from shareholders of the Corporation, under and to the
extent provided in La.R.S. 12:92(D); or (4) any transaction from which he
derived an improper personal benefit. If, after the date hereof, the Louisiana
Business Corporation Law is amended to authorize further elimination or
limitation of the personal liability of directors or officers, then the
liability of a director or an officer of the Corporation shall be eliminated or
limited to the fullest extent permitted by the Louisiana Business Corporation
Law, as so amended.

     B.   Indemnification.  Subject to such limitations as may be determined by
the Board of Directors (provided that no change in such limitations may
adversely affect any claim to indemnification that arises prior to such change),
the Corporation shall indemnify each of its directors to the full extent from
time to time permitted by law, and may so indemnify each of its officers,
against any expenses or costs, including fees, actually or reasonably incurred
by him in connection with any threatened, pending or completed claim action,
suit or proceeding, whether criminal, civil, administrative or investigative
against such person or as to which he is involved solely as a witness or person
required to give evidence

                                      -7-
<PAGE>
 
     C.  Authorization of Further Actions.  The Board of Directors may (1) cause
the Corporation to enter into contracts with its directors and officers
providing for the limitation of liability set forth in this Article to the
fullest extent permitted by law, (2) adopt By-laws or resolutions, or cause the
Corporation to enter into contracts, providing for indemnification of directors
and officers of the Corporation and other persons (including but not limited to
directors and officers of the Corporation's direct and indirect subsidiaries) to
the fullest extent permitted by law and (3) cause the Corporation to exercise
the powers set forth in La.R.S. 12:83F, notwithstanding that some or all of the
members of the Board of Directors acting with respect to the foregoing may be
parties to such contracts or beneficiaries of such By-laws or resolutions or the
exercise of such powers. No repeal or amendment of any such By-laws or
resolutions limiting the right to indemnification thereunder shall affect the
entitlement of any person to indemnification whose claim thereto results from
conduct occurring prior to the date of such repeal or amendment.

     D.  Subsidiaries.  The Board of Directors may cause the Corporation to
approve for its direct and indirect subsidiaries limitation of liability and
indemnification provisions comparable to the foregoing.

     E.  Amendment.  In addition to any other votes required by law or these
Articles of Incorporation (and notwithstanding the fact that a lesser percentage
may be specified by law or these Articles of Incorporation), the affirmative
vote of the holders of at least 80% of the Total Voting Power shall be required
to repeal this Article or to amend this Article so as to reduce the limitation
of liability set forth herein or the rights to indemnification of any person or
the powers of the Board of Directors provided in this Article, and any amendment
or repeal of this Article shall not adversely affect any indemnification or
limitation of liability of a director or officer of the Corporation under this
Article with respect to any action or inaction occurring prior to the time of
such amendment or repeal.

                                  ARTICLE IX
                                   REVERSION

     Cash, property or share dividends, shares issuable to shareholders in
connection with a reclassification of stock, and the redemption price of
redeemed shares, that are not claimed by the shareholders entitled thereto
within one year after the dividend or redemption price became payable or the
shares became issuable, despite reasonable efforts by the Corporation to pay the
dividend or redemption price or deliver the certificates for the shares to such
shareholders within such time, shall at the expiration of such time, revert in
full ownership to the Corporation, and the Corporation's obligation to pay such
dividend or redemption price or issue such shares, as the case may be, shall
thereupon cease; provided, however, that the Board of Directors may, at any
time, for any reason satisfactory to it, but need not, authorize (1) payment of
the amount of any cash or property dividend or redemption price or (2) issuance
of any shares, ownership of which has reverted to the Corporation pursuant to
this Article, to the person or entity who or which would be entitled thereto had
such reversion not occurred.

                       SPECIAL MEETINGS OF SHAREHOLDERS

     A.  Special meetings of shareholders, for any purpose or purposes, may be
called in any manner set forth in the By-laws, provided that the power of
shareholders as such to call or cause to be called special meetings shall be
governed exclusively by paragraph B of this Article.

     B.  At any time, upon the written request of any shareholder or group of
shareholders holding in the aggregate at least a majority of the Total Voting
Power, the Secretary of the Corporation shall call a special meeting of
shareholders to be held at the registered office of the Corporation at such time
as the Secretary may fix not less than 15 nor more than 60 days after the
receipt of said request, and if the Secretary shall neglect or refuse to fix
such time or to give notice of the meeting, the shareholder or shareholders
making the request may do so. Such requests must state the specific purpose or
purposes of the proposed special meeting, and the business to be conducted
thereat shall be limited to such purpose or purposes.

                             SHAREHOLDER MEETINGS

the Corporation or at such other place, within or without the State of

shareholders shall be held each year on the date and at the time as the Board of
Directors shall designate, for the purpose of electing directors and of the

months, any shareholder may call such meeting to be held at the registered
office of the Corporation as shown on the records of the Secretary of State of
the State of Louisiana.

     2.3   SPECIAL MEETINGS.  Special meetings of the shareholders, for any
purpose or purposes, may be called by or at the direction of the Board of

shareholders' meeting shall cause written notice of the time, place and purpose
of the meeting to be given to all shareholders entitled to vote at such meeting,

shareholders entitled to vote, arranged alphabetically and certified by the
Secretary or by the agent of the Corporation having charge of transfers of
shares, showing the number and class of shares held by each such shareholder on
the record date for the meeting and confirming the number of votes per share as
to which each such shareholder is entitled, shall be produced on the request of
any shareholder.

     2.6   QUORUM.  At all meetings of shareholders, the holders of a majority
of the total voting power shall constitute a quorum; provided, however, that
this subsection shall not have the effect of reducing the vote required to
approve any matter that may be established by law, the Articles of Incorporation
or these By-laws.

     2.7   VOTING.  When a quorum is present at any shareholders' meeting, the
vote of the holders of a majority of the votes actually cast shall decide each

having the right to vote shall be entitled to vote in person or by proxy

adjournment, notwithstanding the withdrawal of enough shareholders to leave less
than a quorum as fixed in Section 2.6 of these By-laws, or the refusal of any
shareholders to vote.

     2.11  LACK OF QUORUM.  If a meeting cannot be organized because a quorum
has not attended, the shareholders present may, by vote of the holders of a
majority of the votes actually cast, adjourn the meeting to such time and place
as they may determine, subject, however, to the provisions of Section 2.9
hereof. In the case of any meeting called for the election of directors, those

fixed in Section 2.6 hereof, shall nevertheless be deemed to constitute a quorum
for the purpose of electing directors.

     3.1   NUMBER.  All of the corporate powers shall be vested in, and the
business and affairs of the Corporation shall be managed by, a Board of
Directors. Except as otherwise fixed by or pursuant to Article III(B) of the
Articles of Incorporation (as it may be duly amended from time to time) relating

over the Common Stock as to dividends or upon liquidation to elect additional
directors by class vote, the Board of Directors shall consist of seven natural
persons; provided that, if after the last action of the Board of Directors with
respect to nomination of directors prior to the mailing to shareholders of proxy
materials for any meeting of shareholders at which directors are to be elected,
any person or persons named therein to be nominated at the direction of the
Board of Directors becomes unable or unwilling to serve, the foregoing number of
authorized directors shall be automatically reduced by a number equal to the
number of such persons unless the Board of Directors selects a replacement
nominee or nominees. No director need be a shareholder. The Secretary shall have
the power to certify at any time as to the number of directors authorized and as
to the class to which each director has been elected or assigned.

those directors who may be elected by the holders of any class or series of
stock having preference over the Common Stock as to dividends or upon
liquidation (whose term of office may be determined by the Board of Directors
pursuant to Section 3.3), shall be elected by the shareholders at the annual
meeting of shareholders to a term expiring at the next succeeding annual meeting
of shareholders and shall serve until his successor is duly elected and
qualified. If the Board of Directors shall appoint any person to fill a vacancy
on the Board, whether resulting from an increase in the number of directors or
otherwise, such person shall serve a term expiring at the next succeeding annual
meeting of shareholders and until his successor is duly elected and qualified.

                                      -3-

     3.4   GENERAL ELECTION.  At each annual meeting of shareholders, directors
shall be elected to succeed those directors whose terms then expire. No decrease
in the number of directors constituting the Board of Directors shall shorten the
term of any incumbent director.

     3.5   VACANCIES.  Except as otherwise provided in the Articles of
Incorporation or these By-laws, the office of a director shall become vacant if
he dies, resigns or is duly removed from office.

     3.6   FILLING VACANCIES.  Except as otherwise provided in the Articles of
Incorporation or Section 3.8 of these By-laws, any vacancy on the board
(including any vacancy resulting from an increase in the authorized number of
directors or from failure of the shareholders to elect the full number of
authorized directors) may, notwithstanding any resulting absence of a quorum of
directors, be filled by a majority vote of the Board of Directors remaining in
office, provided that the shareholders shall have the right, at any special
meeting called for such purpose prior to such action by the Board, to fill the
vacancy. A director elected pursuant to this section shall serve until the next
shareholders' meeting held for the election of directors of the class to which
he shall have been appointed and until his successor is elected and qualified.

     3.7   NOTICE OF SHAREHOLDER NOMINEES.  Except as otherwise provided in or
pursuant to Section 3.8 of these By-laws, only persons who are nominated in
accordance with the procedures set forth in Article IV(E) of the Articles of
Incorporation shall be eligible for election as directors.

     3.8   DIRECTORS ELECTED BY PREFERRED SHAREHOLDERS.  Notwithstanding
anything in these By-laws to the contrary, whenever the holders of any one or
more classes or series of stock having a preference over the Common Stock as to
dividends or upon liquidation shall have the right, voting separately as a
class, to elect one or more directors of the Corporation, the provisions of the
Articles of Incorporation (as they may be duly amended from time to time) fixing
the rights and preferences of such preferred stock shall govern with respect to
the nomination, election, term, removal, vacancies or other related matters with
respect to such directors.

     3.9   COMPENSATION OF DIRECTORS.  Directors shall receive such compensation
for their services, in their capacity as directors, as may be fixed by
resolution of the Board of Directors; provided, however, that nothing herein
contained shall be construed to preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.

                                   SECTION 4

                             MEETINGS OF THE BOARD

Directors, the first meeting of each newly elected Board shall be held
immediately following the shareholders' meeting at which the Board, or any class
thereof, is elected and at the same place as such meeting, and no

                                      -4-
<PAGE>
 
notice of such first meeting shall be necessary for the newly elected directors
in order legally to constitute the meeting.

     4.3   REGULAR MEETINGS; NOTICE.  Regular meetings of the Board may be held
at such times as the Board may from time to time determine. Notice of regular
meetings of the Board of Directors may be given, but no special form of notice
or time of notice shall be necessary.

     4.4   SPECIAL MEETINGS; NOTICE.  Special meetings of the Board may be
called by or at the direction of the Chairman of the Board or the President on
reasonable notice given to each director, either personally or by mail,
reputable courier service, telephone, telex, telecopy or any other comparable
form of facsimile communication. Special meetings shall be called by the
Secretary in like manner and on like notice on the written request of a majority
of the directors and if such officer refuses, or fails or is unable within 24
hours to call a meeting when requested, then the directors making the request
may call the meeting on two days' written notice given to each director. Except
as otherwise required by law, the Articles of Incorporation or these By-laws,
the notice of a special meeting of directors need not state its purpose or
purposes, but if the notice states a purpose or purposes and does not state a
further purpose to consider such other business as may properly come before the
meeting, the business to be conducted at the special meeting shall be limited to
the purpose or purposes stated in the notice.

     4.5   WAIVER OF NOTICE.  Directors present at any regular or special
meeting shall be deemed to have received, or to have waived, due notice thereof,

due notice if, at the beginning of the meeting, he objects to the transaction of
any business because the meeting is not lawfully called.

     4.6   QUORUM.  A majority of the Board shall be necessary to constitute a
quorum for the transaction of business, and except as otherwise provided by law,
the Articles of Incorporation or these By-laws, the acts of a majority of the
directors present at a duly called meeting at which a quorum is present shall be
the acts of the Board. If a quorum is not present at any meeting of the Board of
Directors, the directors present may adjourn the meeting from time to time
without notice other than announcement at the meeting, until a quorum is
present.

     4.7   WITHDRAWAL.  If a quorum was present when the meeting convened, the
directors present may continue to do business, taking action by vote of a
majority of a quorum as fixed in Section 4.6 hereof, until adjournment,
notwithstanding the withdrawal of enough directors to leave less than a quorum
as fixed in Section 4.6 hereof or the refusal of any director present to vote.

     4.8   ACTION BY CONSENT.  Any action that may be taken at a meeting of the
Board, or any committee thereof, may be taken by a consent in writing signed by
all of the directors or by all members of the committee, as the case may be, and
filed with the records of proceedings of the Board or committee.

     4.9   MEETINGS BY TELEPHONE OR SIMILAR COMMUNICATION.  Members of the Board
 may participate at and be present at any meeting of the Board or any committee
 thereof by means of conference telephone or similar communications equipment if
 all persons participating in such meeting can hear and communicate with each
 other.

     5.1   GENERAL.  The Board may designate one or more committees, each
committee to consist of two or more of the directors of the Corporation (and one
or more directors may be named as alternate members to replace any absent or
disqualified regular members), which, to the extent provided by resolution of
the Board or these By-laws, shall have and may exercise the powers of the Board
in the management of the business and affairs of the Corporation, and may have

no such committee shall have power or authority to amend the Articles of
Incorporation, adopt an agreement of merger, consolidation or share exchange,
recommend to the shareholders the sale, lease or exchange of all or
substantially all of the Corporation's assets, a dissolution of the Corporation
or a revocation of dissolution, remove directors, or amend these By-laws; and
unless the resolution expressly so provides, no such committee shall have the
power or authority to declare a dividend or authorize the issuance of stock.
Such committee or committees shall have such name or names as may be stated in
these By-laws, or as may be determined, from time to time, by the Board. Any
vacancy occurring in any such committee shall be filled by the Board, but the
President may designate another director to serve on the committee pending
action by the Board. Each such member of a committee shall hold office during
the term designated by the Board.

     5.2   COMPENSATION COMMITTEE.  The Board shall establish and maintain a
Compensation Committee consisting of two or more directors, each of whom (i)
shall be qualified to the extent appropriate as a "non-employee director" under
Rule 16b-3 of the Securities Exchange Commission and as an "outside director"
under Section 162(m) of the Internal Revenue Code and (ii) shall meet any
further qualifications designated by the Board. The Compensation Committee shall
review and analyze the compensation of the Corporation's executive officers;
review and provide general guidance as to compensation of the Corporation's
other managers; evaluate the performance of the Corporation's executive
officers; administer the Corporation's incentive compensation plan or plans,
including grants thereunder; and perform such other services as may be
designated by the Board.

consisting of at least two directors, a majority of whom are not officers or
employees of the Corporation or of any of its affiliates. The Audit Committee
shall (i) facilitate communication among the Corporation's directors,
management, independent accountants and internal auditing personnel regarding
matters relating to financial accounting, reporting and controls, (ii) assist
the Board of Directors in fulfilling its fiduciary responsibilities as to
accounting policies and reporting practices of the Corporation and all
subsidiaries and the sufficiency of auditing practices with respect thereto by,
among other things, reviewing the scope of audit coverage, including
consideration of the Corporation's accounting practices and procedures and
system of internal accounting controls and reporting to the Board with respect
thereto, (iii) operate as the Board's principal agent in ensuring the
independence of the

                                      -6-
<PAGE>
 
Corporation's independent accountants, the integrity of management and the
adequacy of disclosure to shareholders, and (iv) perform such other services as
may be designated by the Board.

                                   SECTION 6

                                    NOTICES

     7.1   FORM OF DELIVERY.  Whenever under the provisions of law, the Articles
of Incorporation or these By-laws notice is required to be given to any
shareholder or director, it shall not be construed to mean personal notice
unless otherwise specifically provided in the Articles of Incorporation or these
By-laws, but such notice may be given by mail, addressed to such shareholder or
director at his address as it appears on the records of the Corporation, with
postage thereon prepaid, or in such other manner as may be specified in these
By-laws. Notices given by mail shall be deemed to have been given at the time
they are deposited in the United States mail, and all other notices shall be
deemed to have been given upon delivery or transmission to the appropriate
address.

     7.2   WAIVER.  Whenever any notice is required to be given by law, the
Articles of Incorporation or these By-laws, a waiver thereof in writing signed
by the person or persons entitled to such notice, whether before or after the
time stated therein, shall be deemed equivalent thereto. Notice shall be deemed
to have been given to, or waived by, any shareholder who attends a meeting of
shareholders in person, or is represented at such meeting by proxy, without
protesting at the commencement of the meeting the transaction of any business
because the meeting is not lawfully called or convened.

                                   SECTION 8

                                   OFFICERS

     8.1   DESIGNATIONS.  The officers of the Corporation shall be elected by
the directors and shall be the President, Secretary and Treasurer. The Board of
Directors may appoint one or more vice presidents, a chief executive officer, a
chief operating officer, a chief financial or accounting officer and such other
officers as it shall deem necessary. Officers shall hold their offices for such
terms and shall exercise such powers and perform such duties as shall be
determined from time to time by the Board. To the extent permitted by law, more
than one office may be held by a single person.

     8.2   TERM OF OFFICE.  The officers of the Corporation shall hold office at
the pleasure of the Board of Directors. Except as otherwise provided in the
resolution of the Board of Directors

                                      -7-
<PAGE>
 
electing any officer, each officer shall hold office until the first meeting of
the Board of Directors after the annual eeting of shareholders next succeeding
his or her election and until his or her successor is elected and qualified or
until his, or her earlier resignation or removal. Any officer may resign at any
time upon written notice to the Board, Chairman of the Board, President or
Secretary of the Corporation. Such resignation shall take effect at the time
specified therein and acceptance of such resignation shall not be necessary to
make it effective. The Board may remove any officer with or without cause at any
time. Any such removal shall be without prejudice to the contractual rights of
such officers, if any, with the Corporation, but the election of an officer
shall not in and of itself create contractual rights. Any vacancy occurring in
any office of the Corporation by death, resignation, removal or otherwise may be
filled for the unexpired position of the term by the Board at any regular or
special meeting.

     8.3   THE CHAIRMAN OF THE BOARD.  The Board may appoint a Chairman of the
Board who shall preside at meetings of the Board of Directors and the
shareholders and perform such other duties as may be designated by the Board of
Directors or these By-laws. The Chairman of the Board shall not, solely by
virtue of such position, be an officer of the Corporation but may be designated
an officer by the Board of Directors.

     8.4   THE PRESIDENT.  The President shall, unless otherwise provided by the
Board, have general and active responsibility for the management of the business
of the Corporation, shall be the chief executive and chief operating officer of
the Corporation, shall supervise the daily operations of the business of the
Corporation and shall ensure that all orders, policies and resolutions of the
Board are carried out.

     8.5   THE VICE PRESIDENTS.  The Vice Presidents (if any) shall have such
designations and perform such duties as the President or the Board of Directors
shall prescribe.

     8.6   THE SECRETARY.  The Secretary shall attend all meetings of the Board
of Directors and all meetings of the shareholders and record all votes and the
minutes of all proceedings in a book to be kept for that purpose. He shall give,
or cause to be given, notice of all meetings of the shareholders and regular and
special meetings of the Board, and shall perform such other duties as may be
prescribed by the Board or President. He shall keep in safe custody the seal of
the Corporation, if any, and affix such seal to any instrument requiring it.

     8.7   THE TREASURER.  The Treasurer shall have the custody of the corporate
funds and shall keep or cause to be kept full and accurate accounts of receipts
and disbursements in books belonging to the Corporation and shall deposit all
monies and other valuable effects in the name and to the credit of the
Corporation in such depositories as may be designated by the Board of Directors.
He shall keep a proper accounting of all receipts and disbursements and shall
disburse the funds of the Corporation only for proper corporate purposes or as
may be ordered by the Board and shall render to the President and the Board at
the regular meetings of the Board, or whenever they may require it, an account
of all his transactions as Treasurer and of the financial condition and results
of operations of the Corporation.

                                   SECTION 9

                                     STOCK

     9.1   CERTIFICATES.  Every holder of stock in the Corporation shall be
entitled to have a certificate signed by the President or a Vice President and
the Secretary or an Assistant Secretary evidencing the number and class (and
series, if any) of shares owned by him, containing such information as required
by law and bearing the seal of the Corporation. If any stock certificate is
manually signed by a transfer agent or registrar other than the Corporation
itself or an employee of the Corporation, the signature of any such officer may
be a facsimile. In case any officer, transfer agent or registrar who has signed
or whose facsimile signature has been placed upon a certificate shall have
ceased to be an officer, transfer agent or registrar of the Corporation before
such certificate is issued, it may be issued by the Corporation with the same
effect as if such person or entity were an officer, transfer agent or registrar
of the Corporation on the date of issue.

     9.2   MISSING CERTIFICATES.  The President or any Vice President may direct
a new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost,
stolen or destroyed, upon the Corporation's receipt of an affidavit of that fact
from the person claiming the certificate of stock to be lost, stolen or
destroyed. As a condition precedent to the issuance of a new certificate or
certificates, the officers of the Corporation shall, unless otherwise determined
by the President, require the owner of such lost, stolen or destroyed
certificate or certificates, or his legal representative, to (i) give the
Corporation a bond or (ii) enter into a written indemnity agreement, in each
case in an amount appropriate to indemnify the Corporation against any claim
that may be made against the Corporation with respect to the certificate alleged
to have been lost, stolen or destroyed.

     9.3   TRANSFERS.  The shares of stock of the Corporation shall be
transferable only on the books of the Corporation by the holders thereof in
person or by their duly authorized attorneys or legal representatives upon
surrender and cancellation of certificates for a like number of shares. Except
as otherwise required by law, upon surrender to the Corporation or the transfer
agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

                                  SECTION 10

                         DETERMINATION OF SHAREHOLDERS

     For the purpose of determining shareholders entitled to notice of and to
vote at a meeting, or to receive a dividend, or to receive or exercise
subscription or other rights, or to participate in a reclassification of stock,
or in order to make a determination of shareholders for any other proper
purpose, the Board of Directors may fix in advance a record date for
determination of shareholders for such purpose, such date to be not more than 60
days and, if fixed for the purpose of determining

                                      -9-
<PAGE>
 
shareholders entitled to notice of and to vote at a meeting, not less than 10
days, prior to the date on which the action requiring the determination of
shareholders is to be taken.

                                  SECTION 11

                                INDEMNIFICATION

     11.1  DEFINITIONS.  As used in this section the following terms shall have
the meanings set forth below:

           (a) "Board" - the Board of Directors of the Corporation.

           (b) "Claim" - any threatened, pending or completed claim, action,
suit, or proceeding, whether civil, criminal, administrative or investigative
and whether made judicially or extra-judicially, or any separate issue or matter
therein, as the context requires.

           (c) "Determining Body" - (i) those members of the Board who are not
named as parties to the Claim for which indemnification is being sought
("Impartial Directors"), if there are at least three Impartial Directors, (ii) a
committee of at least three Impartial Directors appointed by the Board
(regardless whether the members of the Board of Directors voting on such
appointment are Impartial Directors) or (iii) if there are fewer than three
Impartial Directors or if the Board of Directors or the committee appointed
pursuant to clause (ii) of this paragraph so directs (regardless whether the
members thereof are Impartial Directors), independent legal counsel, which may
be the regular outside counsel of the Corporation.

           (d) "Disbursing Officer" - the President of the Corporation or, if
the President is a party to the Claim for which indemnification is being sought,
any officer not a party to such Claim who is designated by the President to be
the Disbursing Officer with respect to indemnification requests related to the
Claim, which designation shall be made promptly after receipt of the initial
request for indemnification with respect to such Claim.

           (e) "Expenses" - any expenses or costs, including, without
limitation, attorney's fees, judgments, punitive or exemplary damages, fines and
amounts paid in settlement.

           (f) "Indemnitee" - each person who is or was a director or officer of
the Corporation.

     11.2  INDEMNITY.

           (a) To the extent such Expenses exceed the amounts reimbursed or paid
pursuant to policies of liability insurance maintained by the Corporation, the
Corporation shall indemnify each Indemnitee against any Expenses actually and
reasonably incurred by him (as they are incurred) in connection with any Claim
either against him or as to which he is involved solely as a witness or person
required to give evidence, by reason of his position (i) as a director or
officer of the Corporation, (ii) as a director or officer of any subsidiary of
the Corporation, (iii) as a fiduciary with

                                      -10-
<PAGE>
 
respect to any employee benefit plan of the Corporation, or (iv) as a director,
officer, partner, employee or agent of another corporation, partnership, joint
venture, trust or other for-profit or not-for-profit entity or enterprise, if
such position is or was held at the request of the Corporation, whether relating
to service in such position before or after the effective date of this Section,
if he (i) is successful in his defense of the claim on the merits or otherwise
or (ii) has been found by the Determining Body (acting in good faith) to have
met the Standard of Conduct (defined below); provided that (A) the amount
otherwise payable by the Corporation may be reduced by the Determining Body to
such amount as it deems proper if it determines that the Claim involved the
receipt of a personal benefit by Indemnitee, and (B) no indemnification shall be
made in respect of any Claim as to which Indemnitee shall have been adjudged by
a court of competent jurisdiction, after exhaustion of all appeals therefrom, to
be liable for willful or intentional misconduct in the performance of his duty
to the Corporation or to have obtained an improper personal benefit, unless, and
only to the extent that, a court shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as
the court deems proper.

           (b) For purposes of this Section 11, the Standard of Conduct is met
when the conduct by an Indemnitee with respect to which a Claim is asserted was
conduct that was in good faith and that he reasonably believed to be in, or not
opposed to, the best interest of the Corporation, and, in the case of a criminal
action or proceeding, that he had no reasonable cause to believe was unlawful.
The termination of any Claim by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that Indemnitee did not meet the Standard of Conduct.

           (c) Promptly upon becoming aware of the existence of any Claim as to
which he may be indemnified hereunder, Indemnitee shall notify the President of
the Corporation of the Claim and whether he intends to seek indemnification
hereunder. If such notice indicates that Indemnitee does so intend, the
President shall promptly advise the Board thereof and notify the Board that the
establishment of the Determining Body with respect to the Claim will be a matter
presented at the next regularly scheduled meeting of the Board, or if a meeting
of the Board of Directors is not regularly scheduled within 90 calendar days of
such request, the President shall cause a meeting of the Board of Directors to
be called within such period in accordance with these By-laws. After the
Determining Body has been established the President shall inform the Indemnitee
thereof and Indemnitee shall immediately provide the Determining Body with all
facts relevant to the Claim known to him. No later than the 45th day (the
"Determination Date") after its receipt of such information, together with such
additional information as the Determining Body may request of Indemnitee, the
Determining Body shall determine, and shall advise Indemnitee of its
determination, whether Indemnitee has met the Standard of Conduct.

           (d) During such 45-day period, Indemnitee shall promptly inform the
Determining Body upon his becoming aware of any relevant facts not theretofore
provided by him to the Determining Body, unless the Determining Body has
obtained such facts by other means. The providing of such facts to the
Determining Body shall not begin a new 45-day period.

                                      -11-
<PAGE>
 
           (e) The Determining Body shall have no authority to revoke a
determination that Indemnitee met the Standard of Conduct unless Indemnitee (i)
submits fraudulent information to the Determining Body at any time during the 45
days prior to the Determination Date or (ii) fails to comply with the provisions
of subsections (c) or (d) hereof, including without limitation Indemnitee's
obligation to submit information or documents relevant to the Claim reasonably
requested by the Determining Body prior to the Determination Date.

           (f) In the case of any Claim not involving a proposed, threatened or
pending criminal proceeding,

               (i)   if Indemnitee has, in the good faith judgment of the
Determining Body, met the Standard of Conduct, the Corporation may, in its sole
discretion after notice to Indemnitee, assume all responsibility for the defense
of the Claim, and, in any event, the Corporation and the Indemnitee each shall
keep the other informed as to the progress of the defense, including prompt
disclosure of any proposals for settlement; provided that if the Corporation is
a party to the Claim and Indemnitee reasonably determines that there is a
conflict between the positions of the Corporation and Indemnitee with respect to
the Claim, then Indemnitee shall be entitled to conduct his defense, with
counsel of his choice; and provided further that Indemnitee shall in any event
be entitled at his expense to employ counsel chosen by him to participate in the
defense of the Claim; and

               (ii)  the Corporation shall fairly consider any proposals by
Indemnitee for settlement of the Claim. If the Corporation (A) proposes a
settlement acceptable to the person asserting the Claim, or (B) believes a
settlement proposed by the person asserting the Claim should be accepted, it
shall inform Indemnitee of the terms thereof and shall fix a reasonable date by
which Indemnitee shall respond. If Indemnitee agrees to such terms, he shall
execute such documents as shall be necessary to effect the settlement. If he
does not agree he may proceed with the defense of the Claim in any manner he
chooses, but if he is not successful on the merits or otherwise, the
Corporation's obligation to indemnify him for any Expenses incurred following
his disagreement shall be limited to the lesser of (A) the total Expenses
incurred by him following his decision not to agree to such proposed settlement
or (B) the amount the Corporation would have paid pursuant to the terms of the
proposed settlement. If, however, the proposed settlement would impose upon
Indemnitee any requirement to act or refrain from acting that would materially
interfere with the conduct of his affairs, Indemnitee may refuse such settlement
and proceed with the defense of the Claim, if he so desires, at the
Corporation's expense without regard to the limitations imposed by the preceding
sentence. In no event, however, shall the Corporation be obligated to indemnify
Indemnitee for any amount paid in a settlement that the Corporation has not
approved.

           (g) In the case of a Claim involving a proposed, threatened or
pending criminal proceeding, Indemnitee shall be entitled to conduct the defense
of the claim, and to make all decisions with respect thereto, with counsel of
his choice; provided, however, that the Corporation shall not be obligated to
indemnify Indemnitee for an amount paid in settlement that the Corporation has
not approved.

                                      -12-
<PAGE>
 
           (h) After notifying the Corporation of the existence of a Claim,
Indemnitee may from time to time request the Corporation to pay the Expenses
(other than judgments, fines, penalties or amounts paid in settlement) that he
incurs in pursuing a defense of the Claim prior to the time that the Determining
Body determines whether the Standard of Conduct has been met. If the Disbursing
Officer believes the amount requested to be reasonable, he shall pay to
Indemnitee the amount requested (regardless of Indemnitee's apparent ability to
repay such amount) upon receipt of an undertaking by or on behalf of Indemnitee
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation under the circumstances. If the
disbursing Officer does not believe such amount to be reasonable, the
Corporation shall pay the amount deemed by him to be reasonable and Indemnitee
may apply directly to the Determining Body for the remainder of the amount
requested.

           (i) After the Determining Body has determined that the Standard of
Conduct was met, for so long as and to the extent that the Corporation is
required to indemnify Indemnitee under this Agreement, the provisions of
paragraph (h) shall continue to apply with respect to Expenses incurred after
such time except that (i) no undertaking shall be required of Indemnitee and
(ii) the Disbursing Officer shall pay to Indemnitee such amount of any fines,
penalties or judgments against him which have become final as the Corporation is
obligated to indemnify him.

           (j) Any determination by the Corporation with respect to settlements
of a Claim shall be made by the Determining Body.

           (k) The Corporation and Indemnitee shall keep confidential, to the
extent permitted by law and their fiduciary obligations, all facts and
determinations provided or made pursuant to or arising out of the operation of
this Section, and the Corporation and Indemnitee shall instruct its or his
agents and employees to do likewise.

     11.3  ENFORCEMENT.

           (a) The rights provided by this Section shall be enforceable by
Indemnitee in any court of competent jurisdiction.

           (b) If Indemnitee seeks a judicial adjudication of his rights under
this Section, Indemnitee shall be entitled to recover from the Corporation, and
shall be indemnified by the Corporation against, any and all Expenses actually
and reasonably incurred by him in connection with such proceeding but only if he
prevails therein. If it shall be determined that Indemnitee is entitled to
receive part but not all of the relief sought, then the Indemnitee shall be
entitled to be reimbursed for all Expenses incurred by him in connection with
such judicial adjudication if the amount to which he is determined to be
entitled exceeds 50% of the amount of his claim. Otherwise, the Expenses
incurred by Indemnitee in connection with such judicial shall be appropriately
prorated.

           (c) In any judicial proceeding described in this subsection, the
Corporation shall bear the burden of proving that Indemnitee is not entitled to
any Expenses sought with respect to any Claim.

     11.4  SAVING CLAUSE.  If any provision of this Section is determined by a
court having jurisdiction over the matter to require the Corporation to do or
refrain from doing any act that is in violation of applicable law, the court
shall be empowered to modify or reform such provision so that, as modified or
reformed, such provision provides the maximum indemnification permitted by law,
and such provision, as so modified or reformed, and the balance of this Section,
shall be applied in accordance with their terms. Without limiting the generality
of the foregoing, if any portion of this Section shall be invalidated on any
ground, the Corporation shall nevertheless indemnify an Indemnitee to the full
extent permitted by any applicable portion of this Section that shall not have
been invalidated and to the full extent permitted by law with respect to that
portion that has been invalidated.

     11.5  NON-EXCLUSIVITY.

           (a) The indemnification and advancement of Expenses provided by or
granted pursuant to this Section shall not be deemed exclusive of any other
rights to which Indemnitee is or may become entitled under any statute, article
of incorporation, by-law, authorization of shareholders or directors, agreement,
or otherwise.

           (b) It is the intent of the Corporation by this Section to indemnify
and hold harmless Indemnitee to the fullest extent permitted by law, so that if
applicable law would permit the Corporation to provide broader indemnification
rights than are currently permitted, the Corporation shall indemnify and hold
harmless Indemnitee to the fullest extent permitted by applicable law
notwithstanding that the other terms of this Section would provide for lesser
indemnification.

     11.6  SUCCESSORS AND ASSIGNS.  This Section shall be binding upon the
Corporation, its successors and assigns, and shall inure to the benefit of the
Indemnitee's heirs, personal representatives, and assigns and to the benefit of
the Corporation, its successors and assigns.

     11.7  INDEMNIFICATION OF OTHER PERSONS.  The Corporation may indemnify any
person not covered by Sections 11.1 through 11.6 to the extent provided in a
resolution of the Board or a separate section of these By-laws.

                                  SECTION 12

                       ADOPTION AND AMENDMENT OF BY-LAWS

     By-laws of the Corporation may be adopted and amended as provided in the
Articles of Incorporation.

limitations specified by law and in the Articles of Incorporation.

     13.2  VOTING OF SHARES OWNED BY CORPORATION.  Unless otherwise directed by
the Board, any shares of capital stock issued by a wholly-owned subsidiary of
the Corporation may be voted by the President of the Corporation, or by any
person authorized to do so by the President, at any shareholders' meeting of the
subsidiary (or in connection with any written consent in lieu thereof).

     13.3  FISCAL YEAR.  Until otherwise determined by the Board of Directors,
the Corporation shall have a fiscal year ending December 31.

     13.4  SEAL.  The Board of Directors may adopt a corporate seal, which shall
have inscribed thereon the name of the Corporation. The seal may be used by
causing it or a facsimile thereof to be impressed or affixed or reproduced or
otherwise. Failure to affix the seal shall not, however, affect the validity of
any instrument.

     13.5  GENDER.  All pronouns and variations thereof used in these By-laws
shall be deemed to refer to the masculine, feminine or neuter gender, singular
or plural, as the identity of the person, persons, entity or entities referred

140.2 of the Louisiana Business Corporation Law (La.R.S. 12:135 through 140.2)
do not apply to control share acquisitions of shares of the Corporation.

                              INDEMNITY AGREEMENT


     This  Agreement is made as of ________________, 1997, by and
between Omni  Energy Services Corp., a Louisiana corporation (the
"Corporation"), and _______________  ("Indemnitee").

     In consideration of Indemnitee's continued service after the date hereof,
the Corporation and Indemnitee do hereby agree as follows:

     1.   AGREEMENT TO SERVE.  Indemnitee agrees to serve as a
[director/officer] of the Corporation for so long as he is elected or appointed
or until such earlier time as he tenders his resignation in writing.

     2.   DEFINITIONS.  As used in this Agreement:

          (a)  The term "Expenses" shall mean any expenses or costs (including,
without limitation, attorney's fees, judgments, punitive or exemplary damages,
fines and amounts paid in settlement). If any of the foregoing amounts paid on
behalf of Indemnitee are not deductible by Indemnitee for federal or state
income tax purposes, the Corporation will reimburse Indemnitee for tax liability
with respect thereto by paying to Indemnitee an amount which, after taking into
account taxes on such amount, equals Indemnitee's incremental tax liability.

          (b)  The term "Claim" shall mean any threatened, pending or completed
claim, action, suit, or proceeding, whether civil, criminal, administrative or
investigative and whether made judicially or extra-judicially, or any separate
issue or matter therein, as the context requires.

          (c)  The term "Determining Body" shall mean (i) those members of the
Board of Directors who are not named as parties to the Claim for which
indemnification is being sought ("Impartial Directors"), if there are at least
three Impartial Directors, or (ii) a committee of at least three directors
appointed by the Board of Directors (regardless whether the members of the Board
of Directors voting on such appointment are Impartial Directors) and composed of
Impartial Directors or (iii) if there are fewer than three Impartial Directors
or if the Board of Directors or a committee appointed thereby so directs
(regardless whether the members thereof are Impartial Directors), independent
legal counsel, which may be the regular outside counsel of the Corporation.

     3.   LIMITATION OF LIABILITY.

          To the fullest extent permitted by Article VIII of the Articles of
Incorporation of the Corporation in effect on the date hereof and, if and to the
extent such Article VIII is amended to permit further limitations, in effect at
any time prior to the determination of liability that would exist but for the
provisions of this Agreement, Indemnitee shall not be liable for breach of his
fiduciary duty as a director or officer.

                                      -1-

     4.   MAINTENANCE OF INSURANCE AND SELF-INSURANCE.

          (a)  The Corporation represents that it presently main-tains in force
and effect the following directors and officers liability insurance ("D&O
Insurance") policies (the "Insurance Policies"):

                 Insurer          Policy No.          Coverage


Subject only to the provisions of Section 4(b) hereof, the Corpo-ration hereby
agrees that, so long as Indemnitee shall continue to serve as a [director or
officer] (or shall continue at the request of the Corporation to serve in any
capacity referred to in Section 5(a) hereof) and thereafter so long as
Indemnitee shall be subject to any possible Claim, the Corporation shall use its
best efforts to purchase and maintain in effect for the benefit of Indemnitee
one or more valid and enforceable policy or policies of D&O Insurance providing,
in all respects, coverage at least comparable to that currently provided
pursuant to the Insurance Policies, provided that the Corporation shall have no
obligation to provide primary coverage in excess of $_____ million or excess
coverage in excess of $_____ million.

          (b)  The Corporation shall not be required to purchase and maintain
the Insurance Policies in effect if D&O Insurance is not reasonably available or
if, in the reasonable business judg-ment of the then directors of the
Corporation, either (i) the premium cost for such insurance is excessive in
light of the amount of coverage or (ii) the coverage provided by such insurance
is so limited by exclusions, retentions, deductibles or otherwise that there is
insufficient benefit from such insurance.

          (c)  If the Corporation does not purchase and maintain in effect the
Insurance Policies pursuant to the provisions of Section 4(b) hereof, the
Corporation agrees to hold harmless and indemnify Indemnitee to the full extent
of the coverage that would otherwise have been provided for the benefit of
Indemnitee pursuant to the Insurance Policies.

     5.   ADDITIONAL INDEMNITY.

          (a)  To the extent any Expenses incurred by Indemnitee are in excess
of the amounts reimbursed or indemnified pursuant to the provisions of Section 4
hereof, the Corporation shall indemnify and hold harmless Indemnitee against any
such Expenses actually and reasonably incurred, as they are incurred, in
connection with any Claim against Indemnitee (whether as a subject of or party
to, or a proposed or threatened subject of or party to, the Claim) or in which
Indemnitee is involved solely as a witness or person required to give evidence,
by reason of his position

               (i)   as a director or officer of the Corporation

                                      -2-
<PAGE>
 
               (ii)  as a director or officer of any subsidiary of the
Corporation or as a fiduciary with respect to any employee benefit plan of the
Corporation or

               (iii) as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other for profit or not for
profit entity or enterprise, if such position is or was held at the request of
the Corporation, whether relating to service in such position before or after
the effective date of this Agreement, if (i) the Indemnitee is successful in his
defense of the Claim on the merits or otherwise or (ii) the Indemnitee has been
found by the Determining Body (acting in good faith) to have met the Standard of
Conduct; provided that (a) the amount of Expenses for which the Corporation
shall indemnify Indemnitee may be reduced by the Determining Body to such amount
as it deems proper if it determines in good faith that the Claim involved the
receipt of a personal benefit by Indemnitee and (b) no indemnification shall be
made in respect of any Claim as to which Indemnitee shall have been adjudged by
a court of competent jurisdiction, after exhaustion of all appeals therefrom, to
be liable for willful or intentional misconduct in the performance of his duty
to the Corporation or to have obtained an improper personal benefit, unless, and
only to the extent that, a court shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as
the court shall deem proper; and provided further that, if the Claim involves
Indemnitee by reason of his position with an entity or enterprise described in
clause (ii) or (iii) of this Section 5(a) and if Indemnitee may be entitled to
indemnification with respect to such Claim from such entity or enterprise,
Indemnitee shall be entitled to indemnification hereunder only (x) if he has
applied to such entity or enterprise for indemnification with respect to the
Claim and (y) to the extent that indemnification to which he would be entitled
hereunder but for this proviso exceeds the indemnification paid by such other
entity or enterprise.

          (b)  For purposes of this Agreement, the Standard of Conduct is met
when conduct by an Indemnitee with respect to which a Claim is asserted was
conduct that he reasonably believed to be in, or not opposed to, the best
interest of the Corporation, and, in the case of a Claim which is a criminal
action or proceeding, conduct that the Indemnitee had no reasonable cause to
believe was unlawful. The termination of any Claim by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that Indemnitee did not meet the
Standard of Conduct.

          (c)  Promptly upon becoming aware of the existence of any Claim,
Indemnitee shall notify the Chief Executive Officer of the existence of the
Claim, who shall promptly advise the members of the Board of Directors and that
establishing the Determining Body will be a matter presented at the next
regularly scheduled meeting of the Board of Directors. After the Determining
Body has been established the Chief Executive Officer shall inform Indemnitee
thereof and Indemnitee shall immediately notify the Determining Body of all
facts relevant to the Claim known to such Indemnitee. Within 60 days of the
receipt of such notice and information, together with such additional
information as the Determining Body may request of Indemnitee, the Determining
Body shall report to Indemnitee of its determination whether Indemnitee has met
the Standard of Conduct. The Determining Body may extend the period of time
for determining whether the Standard of

                                      -3-
<PAGE>
 
Conduct has been met, but in no event shall such period of time be extended
beyond an additional sixty days.

          (d)  If, after determining that the Standard of Conduct has been met,
the Determining Body obtains facts of which it was not aware at the time it made
such determination, the Determining Body on its own motion, after notifying
Indemnitee and providing him an opportunity to be heard, may, on the basis of
such facts, revoke such determination, provided that, in the absence of actual
fraud by Indemnitee, no such revocation may be made later than thirty days after
final disposition of the Claim.

          (e)  Indemnitee shall promptly inform the Determining Body upon his
becoming aware of any relevant facts not theretofore provided by him to the
Determining Body, unless the Determining Body has obtained such facts by other
means.

          (f)  In the case of any Claim not involving a proposed, threatened or
pending criminal proceeding,

               (i)   if Indemnitee has, in the good faith judgment of the
Determining Body, met the Standard of Conduct, the Corporation may, in its sole
discretion, assume all responsibility for the defense of the Claim, and, in any
event, the Corporation and Indemnitee each shall keep the other informed as to
the progress of the defense of the Claim, including prompt disclosure of any
proposals for settlement; provided that if the Corporation is a party to the
Claim and Indemnitee reasonably determines that there is a conflict between the
positions of the Corporation and Indemnitee with respect to the Claim, then
Indemnitee shall be entitled to conduct his defense with counsel of his choice;
and provided further that Indemnitee shall in any event be entitled at his
expense to employ counsel chosen by him to participate in the defense of the
Claim; and

               (ii)  the Corporation shall fairly consider any proposals by
Indemnitee for settlement of the Claim. If the Corporation proposes a settlement
of the Claim and such settlement is acceptable to the person asserting the Claim
or the Corporation believes a settlement proposed by the person asserting the
Claim should be accepted, it shall inform Indemnitee of the terms of such
proposed settlement and shall fix a reasonable date by which Indemnitee shall
respond. If Indemnitee agrees to such terms, he shall execute such documents as
shall be necessary to make final the settlement. If Indemnitee does not agree
with such terms, Indemnitee may proceed with the defense of the Claim in any
manner he chooses, provided that if Indemnitee is not successful on the merits
or otherwise, the Corporation's obligation to indemnify such Indemnitee as to
any Expenses incurred following his disagreement shall be limited to the lesser
of (A) the total Expenses incurred by Indemnitee following his decision not to
agree to such proposed settlement or (B) the amount that the Corporation would
have paid pursuant to the terms of the proposed settlement. If, however, the
proposed settlement would impose upon Indemnitee any requirement to act or
refrain from acting that would materially interfere with the conduct of
Indemnitee's affairs, Indemnitee shall be permitted to refuse such settlement
and proceed with the defense of the Claim, if he so desires, at

                                      -4-
<PAGE>
 
the Corporation's expense in accordance with the terms and conditions of this
Agreement without regard to the limitations imposed by the immediately preceding
sentence. In any event, the Corporation shall not be obligated to indemnify
Indemnitee for an amount paid in a settlement that the Corporation has not
approved.

          (g)  In the case of a Claim involving a proposed, threatened or
pending criminal proceeding, Indemnitee shall be entitled to conduct the defense
of the Claim and to make all decisions with respect thereto, with counsel of his
choice; provided that the Corporation shall not be obligated to indemnify
Indemnitee for an amount paid in settlement that the Corporation has not
approved.

          (h)  After notification to the Corporation of the ex-istence of a
Claim, Indemnitee may from time to time request of the Chief Executive Officer
or, if the Chief Executive Officer is a party to the Claim as to which
indemnification is being sought, any officer who is not a party to the Claim and
who is designated by the Chief Executive Officer (the "Disbursing Officer"),
which designation shall be made promptly after receipt of the initial request,
that the Corporation advance to Indemnitee the Expenses (other than fines,
penalties, judgments or amounts paid in settlement) that he incurs in pursuing a
defense of the Claim prior to the time that the Determining Body determines
whether the Standard of Conduct has been met. The Disbursing Officer shall pay
to Indemnitee the amount requested (regardless of Indemnitee's apparent ability
to repay the funds) upon receipt of an undertaking by or on behalf of Indemnitee
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation under the circumstances, provided
that if the Disbursing Officer does not believe such amount to be reasonable, he
shall advance the amount deemed by him to be reasonable and Indemnitee may apply
directly to the Determining Body for the remainder of the amount requested.

          (i)  After a determination that the Standard of Conduct has been met,
for so long as and to the extent that the Corporation is required to indemnify
Indemnitee under this Agreement, the provisions of Paragraph (h) shall continue
to apply with respect to Expenses incurred after such time except that (i) no
undertaking shall be required of Indemnitee and (ii) the Disbursing Officer
shall pay to Indemnitee the amount of any fines, penalties or judgments against
him which have become final for which the Corporation is obligated to indemnify
him or any amount of indemnification ordered to be paid to him by a court.

          (j)  Any determination by the Corporation with respect to settlement
of a Claim shall be made by the Determining Body.

          (k)  The Corporation and Indemnitee shall keep confidential to the
extent permitted by law and their fiduciary obligations all facts and
determinations provided pursuant to or arising out of the operation of this
Agreement and the Corporation and Indemnitee shall instruct its or his agents
and employees to do likewise.

     6.   ENFORCEMENT.

          (a)  The rights provided by this Agreement shall be en-
forceable by Indemnitee in any court of competent jurisdiction.

          (b)  If Indemnitee seeks a judicial adjudication of his rights under,
or to recover damages for breach of, this Agreement, Indemnitee shall be
entitled to recover from the Corporation, and shall be indemnified by the
Corporation against, any and all Expenses actually and reasonably incurred by
him in connection with such proceeding, but only if he prevails therein. If it
shall be determined that Indemnitee is entitled to receive part but not all of
the relief sought, then Indemnitee shall be entitled to be reimbursed for all
Expenses incurred by him in connection with such proceeding if the
indemnification amount to which he is determined to be entitled exceeds 50% of
the amount of his claim. Otherwise, the Expenses incurred by Indemnitee in
connection with such judicial adjudication shall be appropriately prorated.

          (c)  In any judicial proceeding described in this Sec-tion 6, the
Corporation shall bear the burden of proving that Indemnitee is not entitled to
Expenses sought with respect to any Claim.

     7.   SAVING CLAUSE.  If any provision of this Agreement is determined by a
court having jurisdiction over the matter to re-quire the Corporation to do or
refrain from doing any act that is in violation of applicable law, the court
shall be empowered to modify or reform such provision so that, as modified or
reformed, such provision provides the maximum indemnification permitted by law
and such provision, as so modified or reformed, and the balance of this
Agreement, shall be applied in accordance with their terms. Without limiting the
generality of the foregoing, if any portion of this Agreement shall be
invalidated on any ground, the Corporation shall nevertheless indemnify
Indemnitee to the full extent permitted by any applicable portion of this
Agreement that shall not have been invalidated and to the full extent permitted
by law with respect to that portion that has been invalidated.

     8.   NON-EXCLUSIVITY.

          (a)  The indemnification and payment of Expenses provided by or
granted pursuant to this Agreement shall not be deemed exclusive of any other
rights to which Indemnitee is or may become entitled under any statute, article
of incorporation, by-law, authorization of shareholders or directors, agreement
or otherwise.

          (b)  It is the intent of the Corporation by this Agree-ment to
indemnify and hold harmless Indemnitee to the fullest ex-tent permitted by law,
so that if applicable law would permit the Corporation to provide broader
indemnification rights than are currently permitted, the Corporation shall
indemnify and hold harmless Indemnitee to the fullest extent permitted by
applicable law notwithstanding that the other terms of this Agreement would
provide for lesser indemnification.

     9.   COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall constitute the original.

     10.  APPLICABLE LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Louisiana.

     11.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon
Indemnitee and upon the Corporation, its successors and assigns, and shall inure
to the benefit of Indemnitee's heirs, personal representatives, and assigns and
to the benefit of the Corporation, its successors and assigns.

     12.  AMENDMENT.  No amendment, modification, termination or cancellation of
this Agreement shall be effective unless made in writing signed by the
Corporation and Indemnitee. Notwithstanding any amendment or modification to or
termination or cancellation of this Agreement or any portion hereof, Indemnitee
shall be entitled to indemnification in accordance with the provisions hereof
with respect to any acts or omissions of Indemnitee which occur prior to such
amendment, modification, termination or cancellation.

     13.  GENDER.  All pronouns and variations thereof used in this Agreement
shall be deemed to refer to the masculine, feminine or neuter gender, singular
or plural, as the identity of the person, persons, entity or entities refer to
may require.

duly executed and signed as of the date and year first above written.

                                 STOCK INCENTIVE PLAN


               1.   PURPOSE. The purpose of the Stock Incentive Plan (the

          motivate key employees, officers and directors and to strengthen the
          mutuality of interests between such employees, officers and directors
          and Omni's shareholders. Incentives consist of opportunities to
          purchase or receive shares of common stock, $.01 par value per share,
          of Omni (the "Common Stock"), on terms determined under the Plan. As
          used in the Plan, the term "subsidiary" means any corporation of which
          Omni owns (directly or indirectly) within the meaning of Section
          425(f) of the Internal Revenue Code of 1986, as amended (the "Code"),
          50% or more of the total combined voting power of all classes of
          stock.

               2.   ADMINISTRATION.

                    2.1.  COMPOSITION. The Plan shall be administered by the
               Compensation Committee of the Board of Directors of Omni or by a
               subcommittee thereof (the "Committee"). The Committee shall
               consist of not fewer than two members of the Board of Directors,
               each of whom shall (a) qualify as a "non-employee director" under
               Rule 16b-3 under the Securities Exchange Act of 1934 (the "1934
               Act") or any successor rule, and (b) qualify as an "outside
               director" under Section 162(m) of the Code.

                    2.2.  AUTHORITY. The Committee shall have plenary authority
               to award Incentives under the Plan, to interpret the Plan, to
               establish any rules or regulations relating to the Plan that it
               determines to be appropriate, to enter into agreements with
               participants as to the terms of the Incentives (the "Incentive
               Agreements") and to make any other determination that it believes
               necessary or advisable for the proper administration of the Plan.
               Its decisions in matters relating to the Plan shall be final and
               conclusive on the Company and participants. The Committee may
               delegate its authority hereunder to the extent provided in
               Section 3 hereof. The Committee shall not have authority to award
               Incentives under the Plan to directors who are not also employees
               of the Company ("Outside Directors"). Outside Directors may
               receive awards under the Plan only as specifically provided in
               Section 9 hereof.

               3.   ELIGIBLE PARTICIPANTS. Key employees and officers of the
          Company (including officers who also serve as directors of the
          Company) and consultants and advisors to the Company shall become
          eligible to receive Incentives under the Plan when designated by the
          Committee. Employees may be designated individually or by groups or
          categories, as the Committee deems appropriate. With respect to
          participants not subject to Section 16 of the 1934 Act or Section
          162(m) of the Code, the Committee may delegate to appropriate
          personnel of the Company its authority to designate participants, to
          determine the size and type of Incentives to be received by those

                                      -1-
<PAGE>
 
          participants and to determine or modify performance objectives for
          those participants. Outside Directors may participate in the Plan only
          as specifically provided in Section 9 hereof.

               4.   TYPES OF INCENTIVES. Incentives may be granted under the
          Plan to eligible participants in any of the following forms, either
          individually or in combination, (a) incentive stock options and non-
          qualified stock options; (b) restricted stock; and (c) other stock-
          based awards ("Other Stock-Based Awards").

               5.   SHARES SUBJECT TO THE PLAN.

                    5.1.  NUMBER OF SHARES. Subject to adjustment as provided in
               Section 10.5, a total of 1,500,000 shares of Common Stock are
               authorized to be issued under the Plan. Incentives with respect
               to no more than 400,000 shares of Common Stock may be granted
               through the Plan to a single participant in one calendar year. In
               the event that an Incentive granted hereunder expires or is
               terminated or cancelled prior to exercise or payment, any shares
               of Common Stock that were issuable thereunder may again be issued
               under the Plan. In the event that shares of Common Stock are
               issued as Incentives under the Plan and thereafter are forfeited
               or reacquired by the Company pursuant to rights reserved upon
               issuance thereof, such forfeited and reacquired shares may again
               be issued under the Plan. If an Other Stock-Based Award is to be
               paid in cash by its terms, the Committee need not make a
               deduction from the shares of Common Stock issuable under the Plan
               with respect thereto. If and to the extent that an Other Stock-
               Based Award may be paid in cash or shares of Common Stock, the
               total number of shares available for issuance hereunder shall be
               debited by the number of shares payable under such Incentive,
               provided that upon any payment of all or part of such Incentive
               in cash, the total number of shares available for issuance
               hereunder shall be credited with the appropriate number of shares
               represented by the cash payment, as determined in the sole
               discretion of the Committee. Additional rules for determining the
               number of shares granted under the Plan may be made by the
               Committee, as it deems necessary or appropriate.

                    5.2. TYPE OF COMMON STOCK. Common Stock issued under the
               Plan may be authorized and unissued shares or issued shares held
               as treasury shares.

               6.   STOCK OPTIONS. A stock option is a right to purchase shares
          of Common Stock from Omni. Stock options granted under this Plan may
          be incentive stock options or non-qualified stock options. Any option
          that is designated as a non-qualified stock option shall not be
          treated as an incentive stock option. Each stock option granted by the
          Committee under this Plan shall be subject to the following terms and
          conditions:

                    6.1. PRICE. The exercise price per share shall be determined
               by the Committee, subject to adjustment under Section 10.5;
               provided that in no event shall the exercise price be less than
               the Fair Market Value of a share of Common Stock on the date of
               grant, except that in connection with an acquisition,
               consolidation, merger or other extraordinary transaction, options
               may be granted at less than the then Fair Market Value in order
               to 

                                      -2-
<PAGE>
 
               replace options previously granted by one or more parties to such
               transaction (or their affiliates) so long as the aggregate spread
               on such replacement options for any recipient of such options is
               equal to or less than the aggregate spread on the options being
               replaced.

                    6.2.  NUMBER. The number of shares of Common Stock subject
               to the option shall be determined by the Committee, subject to
               Section 5.1 and subject to adjustment as provided in Section
               10.5.

                    6.3. DURATION AND TIME FOR EXERCISE. The term of each stock
               option shall be determined by the Committee. Each stock option
               shall become exercisable at such time or times during its term as
               shall be determined by the Committee. Notwithstanding the
               foregoing, the Committee may accelerate the exercisability of any
               stock option at any time, in addition to the automatic
               acceleration of stock options under Section 10.11.

                    6.4.  MANNER OF EXERCISE. A stock option may be exercised,
               in whole or in part, by giving written notice to the Company,
               specifying the number of shares of Common Stock to be purchased.
               The exercise notice shall be accompanied by the full purchase
               price for such shares. The option price shall be payable in
               United States dollars and may be paid by (a) cash; (b)
               uncertified or certified check; (c) unless otherwise determined
               by the Committee, by delivery of shares of Common Stock held by
               the optionee for at least six months, which shares shall be
               valued for this purpose at the Fair Market Value on the business
               day immediately preceding the date such option is exercised; (d)
               unless otherwise determined by the Committee, by delivering a
               properly executed exercise notice together with irrevocable
               instructions to a broker approved by Omni (with a copy to Omni)
               to promptly deliver to Omni the amount of sale or loan proceeds
               to pay the exercise price; or (e) in such other manner as may be
               authorized from time to time by the Committee.

                    6.5. INCENTIVE STOCK OPTIONS. Notwithstanding anything in
               the Plan to the contrary, the following additional provisions
               shall apply to the grant of stock options that are intended to
               qualify as Incentive Stock Options (as such term is defined in
               Section 422 of the Code):

                         A. Any Incentive Stock Option agreement authorized
                    under the Plan shall contain such other provisions as the
                    Committee shall deem advisable, but shall in all events be
                    consistent with and contain or be deemed to contain all
                    provisions required in order to qualify the options as
                    Incentive Stock Options.

                         B.  All Incentive Stock Options must be granted within
                    ten years from the date on which this Plan is adopted by the
                    Board of Directors.

                         C.  Unless sooner exercised, all Incentive Stock
                    Options shall expire no later than ten years after the date
                    of grant.

                                      -3-
<PAGE>
 
                         D.  No Incentive Stock Options shall be granted to any
                    participant who, at the time such option is granted, would
                    own (within the meaning of Section 422 of the Code) stock
                    possessing more than 10% of the total combined voting power
                    of all classes of stock of the employer corporation or of
                    its parent or subsidiary corporation.

                         E.  The aggregate Fair Market Value (determined with
                    respect to each Incentive Stock Option as of the time such
                    Incentive Stock Option is granted) of the Common Stock with
                    respect to which Incentive Stock Options are exercisable for
                    the first time by a participant during any calendar year
                    (under the Plan or any other plan of Omni or any of its
                    subsidiaries) shall not exceed $100,000. To the extent that
                    such limitation is exceeded, such options shall not be
                    treated, for federal income tax purposes, as Incentive Stock
                    Options.

               7.   RESTRICTED STOCK.

                    7.1. GRANT OF RESTRICTED STOCK. The Committee may award
               shares of restricted stock to such officers and key employees as
               the Committee determines pursuant to the terms of Section 3. An
               award of restricted stock shall be subject to such restrictions
               on transfer and forfeitability provisions and such other terms
               and conditions as the Committee may determine, subject to the
               provisions of the Plan. An award of restricted stock may also be
               subject to the attainment of specified performance goals or
               targets. To the extent restricted stock is intended to qualify as
               performance-based compensation under Section 162(m) of the Code,
               it must be granted subject to the attainment of performance goals
               as described in Section 7.2 below and meet the additional
               requirements imposed by Section 162(m).

                    7.2 PERFORMANCE-BASED RESTRICTED STOCK. To the extent that
               restricted stock granted under the Plan is intended to vest based
               upon the achievement of pre-established performance goals rather
               than solely upon continued employment over a period of time, the
               performance goals pursuant to which the restricted stock shall
               vest shall be any or a combination of the following performance
               measures: earnings per share, return on assets, an economic value
               added measure, shareholder return, earnings, stock price, return
               on equity, return on total capital, safety performance, reduction
               of expenses or increase in cash flow of Omni, a division of Omni
               or a subsidiary. For any performance period, such performance
               objectives may be measured on an absolute basis or relative to a
               group of peer companies selected by the Committee, relative to
               internal goals or relative to levels attained in prior years. The
               Committee may not waive any of the pre-established performance
               goal objectives, except that such objectives shall be waived as
               provided in Section 10.11 hereof, or as may be provided by the
               Committee in the event of death, disability or retirement.

                    7.3.  THE RESTRICTED PERIOD. At the time an award of
               restricted stock is made, the Committee shall establish a period
               of time during which the transfer of the shares of restricted
               stock shall be restricted (the "Restricted Period"). The
               Restricted Period shall be a minimum of three years, except that
               if the vesting of the shares of restricted stock is based upon
               the attainment of performance goals, a minimum Restricted Period
               of one year is 

                                      -4-
<PAGE>
 
               permitted. Each award of restricted stock may have a different
               Restricted Period. The expiration of the Restricted Period shall
               also occur as provided under Section 10.3 and under the
               conditions described in Section 10.11 hereof.

                    7.4.  ESCROW. The participant receiving restricted stock
               shall enter into an Incentive Agreement with the Company setting
               forth the conditions of the grant. Certificates representing
               shares of restricted stock shall be registered in the name of the
               participant and deposited with the Company, together with a stock
               power endorsed in blank by the participant. Each such certificate
               shall bear a legend in substantially the following form:

                    The transferability of this certificate and the shares of
                    Common Stock represented by it are subject to the terms and
                    conditions (including conditions of forfeiture) contained in
                    the Omni Energy Services Corp. Stock Incentive Plan (the
                    "Plan"), and an agreement entered into between the
                    registered owner and Omni Energy Services Corp. thereunder.
                    Copies of the Plan and the agreement are on file at the
                    principal office of Omni Energy Services Corp.

                    7.5. DIVIDENDS ON RESTRICTED STOCK. Any and all cash and
               stock dividends paid with respect to the shares of restricted
               stock shall be subject to any restrictions on transfer,
               forfeitability provisions or reinvestment requirements as the
               Committee may, in its discretion, prescribe in the Incentive
               Agreement.

                    7.6. FORFEITURE. In the event of the forfeiture of any
               shares of restricted stock under the terms provided in the
               Incentive Agreement (including any additional shares of
               restricted stock that may result from the reinvestment of cash
               and stock dividends, if so provided in the Incentive Agreement),
               such forfeited shares shall be surrendered and the certificates
               cancelled. The participants shall have the same rights and
               privileges, and be subject to the same forfeiture provisions,
               with respect to any additional shares received pursuant to
               Section 10.5 due to a recapitalization, merger or other change in
               capitalization.

                    7.7.   EXPIRATION OF RESTRICTED PERIOD. Upon the expiration
               or termination of the Restricted Period and the satisfaction of
               any other conditions prescribed by the Committee, the
               restrictions applicable to the restricted stock shall lapse and a
               stock certificate for the number of shares of restricted stock
               with respect to which the restrictions have lapsed shall be
               delivered, free of all such restrictions and legends, except any
               that may be imposed by law, to the participant or the
               participant's estate, as the case may be.

                    7.8. RIGHTS AS A SHAREHOLDER. Subject to the terms and
               conditions of the Plan and subject to any restrictions on the
               receipt of dividends that may be imposed in the Incentive
               Agreement, each participant receiving restricted stock shall have
               all the rights of a shareholder with respect to shares of stock
               during the Restricted Period, including without limitation, the
               right to vote any shares of Common Stock.

               8.   OTHER STOCK-BASED AWARDS.

                    8.1 TERMS OF OTHER STOCK-BASED AWARDS. The Committee is
               hereby authorized to grant to eligible employees an "Other Stock-
               Based Award", which shall consist of an award, the value of which
               is based in whole or in part on the value of shares of Common
               Stock, that is not an instrument or Award specified in Sections 6
               or 7 of the Plan. Other Stock-Based Awards may be awards of
               shares of Common Stock or may be denominated or payable in,
               valued in whole or in part by reference to, or otherwise based on
               or related to, shares of Common Stock (including, without
               limitation, securities convertible or exchangeable into or
               exercisable for shares of Common Stock), as deemed by the
               Committee, consistent with the purposes of the Plan. The
               Committee shall determine the terms and conditions of any such
               Other Stock-Based Award and may provide that such awards would be
               payable in whole or in part in cash. Except in the case of an
               Other Stock-Based Award granted in assumption of or in
               substitution for an outstanding award of a company acquired by
               the Company or with which the Company combines, the price at
               which securities may be purchased pursuant to any Other Stock-
               Based Award granted under this Plan, or the provision, if any, of
               any such award that is analogous to the purchase or exercise
               price, shall not be less than 100% of the fair market value of
               the securities to which such award relates on the date of grant.

                    8.2  DIVIDEND EQUIVALENTS. In the sole and complete
               discretion of the Committee, an Other Stock-Based Award under
               this Section 8 may provide the holder thereof with dividends or
               dividend equivalents, payable in cash or shares of Common Stock
               on a current or deferred basis.

                    8.3   PERFORMANCE GOALS. Other Stock-Based Awards intended
               to qualify as "performance-based compensation" under Section
               162(m) of the Code shall be paid based upon the achievement of
               pre-established performance goals. The performance goals pursuant
               to which Other Stock-Based Awards granted under the Plan shall be
               earned shall be any or a combination of the following performance
               measures: earnings per share, return on assets, an economic value
               added measure, shareholder return, earnings, stock price, return
               on equity, return on total capital, safety performance, reduction
               of expenses or increase in cash flow of the Company, a division
               of the Company or a subsidiary. For any performance period, such
               performance goals may be measured on an absolute basis or
               relative to a group of peer companies selected by the Committee,
               relative to internal goals or relative to levels attained in
               prior years. The Committee may not waive any of the pre-
               established performance goal objectives if such Other Stock-Based
               Award is intended to constitute "performance-based compensation"
               under Section 162(m), except that such objectives shall be waived
               as provided in Section 10.11 hereof, or as may be provided by the
               Committee in the event of death, disability or retirement.

                    8.4. NOT A SHAREHOLDER. The grant of an Other Stock-Based
               Award to a participant shall not create any rights in such
               participant as a shareholder of the Company, 

                                      -6-

               until the issuance of shares of Common Stock with respect to an
               award, at which time such stock shall be considered issued and
               outstanding.

               9. STOCK OPTIONS FOR OUTSIDE DIRECTORS.

                    9.1  GRANT OF OPTIONS. Upon consummation of the Company's
               initial public offering (the "IPO") of its Common Stock, each
               Outside Director shall be granted non-qualified options to
               purchase 10,000 shares of Common Stock. At any time thereafter
               that an Outside Director first becomes a member of the Board of
               Directors of Omni, such Outside Director shall also be granted
               non-qualified options to purchase 10,000 shares of Common Stock.
               In addition, beginning with the 1998 annual meeting of
               shareholders and for as long as the Plan remains in effect and
               shares of Common Stock remain available for issuance hereunder,
               each Outside Director shall be automatically granted a non-
               qualified stock option to purchase 5,000 shares of Common Stock
               on the day following the annual meeting of stockholders of Omni.

                    9.2 EXERCISABILITY OF STOCK OPTIONS. The stock options
               granted to Outside Directors under this Section 9 shall become
               exercisable one year after grant and shall expire ten years
               following the date of grant.

                    9.3 EXERCISE PRICE. The exercise price of the options
               granted upon consummation of the IPO shall be equal to the IPO
               price. The exercise price of the options granted to Outside
               Directors thereafter shall be equal to the Fair Market Value, as
               defined in the Plan, of a share of Common Stock on the date of
               grant. The exercise price may be paid as provided in Section 6.4
               hereof.

                    9.4 EXERCISE AFTER TERMINATION OF BOARD SERVICE. In the
               event an Outside Director ceases to serve on the Board, the stock
               options granted hereunder must be exercised, to the extent
               otherwise exercisable at the time of termination of Board
               service, within three months from termination of Board service;
               provided, however, that in the event of termination of Board
               service as a result of death, disability or retirement on or
               after reaching age 65, the stock options must be exercised, to
               the extent exercisable at the time of termination of Board
               service, within 18 months from the date of termination of Board
               service; and further provided, that no stock options may be
               exercised later than ten years after the date of grant.

               10.  GENERAL.

                    10.1.  DURATION. Subject to Section 10.10, the Plan shall
               remain in effect until all Incentives granted under the Plan have
               either been satisfied by the issuance of shares of Common Stock
               or the payment of cash or been terminated under the terms of the
               Plan and all restrictions imposed on shares of Common Stock in
               connection with their issuance under the Plan have lapsed.

                    10.2. TRANSFERABILITY. No Incentives granted hereunder may
               be transferred, pledged, assigned or otherwise encumbered by a
               participant except: (a) by will; (b) by the laws of descent and
               distribution; (c) pursuant to a domestic relations order, as
               defined in the Code, if permitted by the Committee and so
               provided in the Incentive Agreement or an amendment thereto; or
               (d) as to options only, if permitted by the Committee and so
               provided in the Incentive Agreement or an amendment thereto, (i)
               to Immediate Family Members, (ii) to a partnership in which
               Immediate Family Members, or entities in which Immediate Family
               Members are the sole owners, members or beneficiaries, as
               appropriate, are the sole partners, (iii) to a limited liability
               company in which Immediate Family Members, or entities in which
               Immediate Family Members are the sole owners, members or
               beneficiaries, as appropriate, are the sole members, or (iv) to a
               trust for the sole benefit of Immediate Family Members.
               "Immediate Family Members" shall be defined as the spouse and
               natural or adopted children or grandchildren of the participant
               and their spouses. To the extent that an Incentive Stock Option
               is permitted to be transferred during the lifetime of the
               participant, it shall be treated thereafter as a nonqualified
               stock option. Any attempted assignment, transfer, pledge,
               hypothecation or other disposition of Incentives, or levy of
               attachment or similar process upon Incentives not specifically
               permitted herein, shall be null and void and without effect.

                    10.3. EFFECT OF TERMINATION OF EMPLOYMENT OR DEATH. Except
               as provided in Section 9.4 with respect to Outside Directors, in
               the event that a participant ceases to be an employee of the
               Company for any reason, including death, disability, early
               retirement or normal retirement, any Incentives may be exercised,
               shall vest or shall expire at such times as may be determined by
               the Committee in the Incentive Agreement. The Committee has
               complete authority to modify the treatment of an Incentive in the
               event of termination of employment of a participant by means of
               an amendment to the Incentive Agreement. Consent of the
               participant to the modification is required only if the
               modification materially impairs the rights previously provided to
               the participant in the Incentive Agreement.

                    10.4. ADDITIONAL CONDITION. Anything in this Plan to the
               contrary notwithstanding: (a) the Company may, if it shall
               determine it necessary or desirable for any reason, at the time
               of award of any Incentive or the issuance of any shares of Common
               Stock pursuant to any Incentive, require the recipient of the
               Incentive, as a condition to the re-ceipt thereof or to the
               receipt of shares of Common Stock issued pursuant thereto, to
               deliver to the Company a written representation of present
               intention to acquire the Incentive or the shares of Common Stock
               issued pursuant thereto for his own account for investment and
               not for distribution; and (b) if at any time the Company further
               determines, in its sole discretion, that the listing,
               registration or qualifi-cation (or any updating of any such
               document) of any Incen-tive or the shares of Common Stock
               issuable pursuant thereto is necessary on any securities exchange
               or under any federal or state securities or blue sky law, or that
               the consent or approval of any governmental regulatory body is
               necessary or desirable as a condition of, or in connection with
               the award of any Incentive, the issuance of shares of Common
               Stock pursuant thereto, or the removal of any restrictions
               imposed on such shares, such Incentive shall not be awarded or
               such shares of Common Stock shall not be issued or such
               restrictions shall not be removed, as the case may be, in whole
               or in part, unless such listing, registration, 

                                      -8-
<PAGE>
 
               qualification, consent or approval shall have been effected or
               obtained free of any conditions not acceptable to the Company.

                    10.5.  ADJUSTMENT. In the event of any merger, consolidation
               or reorganization of the Company with any other corporation or
               corporations, there shall be substituted for each of the shares
               of Common Stock then subject to the Plan, including shares
               subject to restrictions, options or achievement of performance
               objectives, the number and kind of shares of stock or other
               securities to which the holders of the shares of Common Stock
               will be entitled pursuant to the transaction. In the event of any
               recapitalization, stock dividend, stock split, combination of
               shares or other change in the Common Stock, the number of shares
               of Common Stock then subject to the Plan, including shares
               subject to outstanding Incentives, shall be adjusted in
               proportion to the change in outstanding shares of Common Stock.
               In the event of any such adjustments, the purchase price of any
               option, the performance objectives of any Incentive, and the
               shares of Common Stock issuable pursuant to any Incentive shall
               be adjusted as and to the extent appropriate, in the reasonable
               discretion of the Committee, to provide participants with the
               same relative rights before and after such adjustment. No
               substitution or adjustment shall require the Company to issue a
               fractional share under this Plan and the substitution or
               adjustment shall be limited by deleting any fractional share.

                    10.6.  INCENTIVE AGREEMENTS. The terms of each Incentive
               granted to an employee, officer, consultant or advisor shall be
               stated in an agreement approved by the Committee.

                    10.7. WITHHOLDING. 

                          A.  The Company shall have the right to withhold from
                    any payments made under the Plan or to collect as a
                    condition of payment, any taxes required by law to be
                    withheld. At any time that a participant is required to pay
                    to the Company an amount required to be withheld under
                    applicable income tax laws in connection with the issuance
                    of Common Stock, the lapse of restrictions on Common Stock
                    or the exercise of an option, the participant may, subject
                    to disapproval by the Committee, satisfy this obligation in
                    whole or in part by electing (the "Election") to have the
                    Company withhold shares of Common Stock having a value equal
                    to the amount required to be withheld. The value of the
                    shares to be withheld shall be based on the Fair Market
                    Value of the Common Stock on the date that the amount of tax
                    to be withheld shall be determined ("Tax Date").

                          B. Each Election must be made prior to the Tax Date.
                    The Committee may disapprove of any Election, may suspend or
                    terminate the right to make Elections, or may provide with
                    respect to any Incentive that the right to make Elections
                    shall not apply to such Incentive. If a participant makes an
                    election under Section 83(b) of the Internal Revenue Code
                    with respect to shares of restricted stock, an Election is
                    not permitted to be made.

                    10.8. NO CONTINUED EMPLOYMENT. No participant under the Plan
               shall have any right, because of his or her participation, to
               continue in the employ of the Company for any period of time or
               to any right to continue his or her present or any other rate of
               compensation.

                    10.9.  DEFERRAL PERMITTED. Payment of cash or distribution
               of any shares of Common Stock to which a participant is entitled
               under any Incentive shall be made as provided in the Incentive
               Agreement. Payment may be deferred at the option of the
               participant if provided in the Incentive Agreement.

                    10.10. AMENDMENTS TO OR TERMINATION OF THE PLAN.

                           A.  The Board may amend, suspend or terminate the
                    Plan or any portion thereof at any time, provided that no
                    amendment shall be made without stockholder approval if such
                    approval is necessary to comply with any tax or regulatory
                    requirement, including any approval necessary to qualify
                    Incentives as "performance- based" compensation under
                    Section 162(m) or any successor provision, if such
                    qualification is deemed necessary or advisable by the
                    Committee.

                           B.  Any provision of this Plan or any Incentive
                    Agreement to the contrary notwithstanding, the Committee may
                    cause any Incentive granted hereunder to be cancelled in
                    consideration of a cash payment or alternative Incentive
                    made to the holder of such cancelled Incentive equal in
                    value to such cancelled Incentive. The determinations of
                    value under this subparagraph shall be made by the Committee
                    in its sole discretion.

                    10.11. CHANGE OF CONTROL.

                           A. "Change of Control" shall mean:

                              1.   the acquisition by any individual, entity or
                         group (within the meaning of Section 13(d)(3) or

                         (within the meaning of Rule 13d-3 promulgated under the
                         1934 Act) of more than 50% of the outstanding shares of
                         the Common Stock; provided, however, that for purposes
                         of this subsection 1., the following shall not
                         constitute a Change of Control:

                                   (a)  any acquisition of Common Stock directly
                              or indirectly from Omni, or Advantage Capital
                              Companies,

                                   (b)  any acquisition of Common Stock by Omni,

                                      -10-
<PAGE>
 
                                   (c)  any acquisition of Common Stock by any
                              employee benefit plan (or related trust) sponsored
                              or maintained by Omni or any corporation
                              controlled by Omni, or

                                   (d)  any acquisition of Common Stock by any
                              corporation pursuant to a transaction that
                              complies with clauses (a), (b) and (c) of
                              subsection (A)(3) of this Section 10.11; or

                              2.   individuals who, as of the date of adoption
                         of the Plan by the Board of Directors of Omni (the
                         "Adoption Date"), constitute the Board (the "Incumbent
                         Board") cease for any reason to constitute at least a
                         majority of the Board; provided, however, that any
                         individual becoming a director subsequent to the
                         Adoption Date whose election, or nomination for
                         election by the Company's shareholders, was approved by
                         a vote of at least a majority of the directors then
                         comprising the Incumbent Board shall be considered a
                         member of the Incumbent Board, unless such individual's
                         initial assumption of office occurs as a result of an
                         actual or threatened election contest with respect to
                         the election or removal of directors or other actual or
                         threatened solicitation of proxies or consents by or on
                         behalf of a person other than the Incumbent Board; or

                              3.   approval by the stockholders of Omni of a
                         reorganization, merger or consolidation, or sale or
                         other disposition of all of substantially all of the
                         assets of the Company (a "Business Combination"), in
                         each case, unless, following such Business Combination,

                                   (a)  all or substantially all of the
                              individuals and entities who were the beneficial
                              owners of Omni's outstanding common stock and
                              Omni's voting securities entitled to vote

                                   (c)  at least a majority of the members of
                              the board of directors of the corporation

                    action by any person.

                         C.   No later than 30 days after the approval by the

                    Subsections A.3 and A.4 of this Section 10.11, and no later
                    than 30 days after a Change of Control of the type described
                    in Subsections A.1 and A.2 of this Section 10.11 of the
                    Plan, the Committee (as the Committee was composed
                    immediately prior to such Change of Control and
                    notwithstanding any removal or attempted removal of some or
                    all of the members thereof as directors or Committee
                    members), acting in its sole discretion without the consent
                    or approval of any participant, may act to effect one or
                    more of the alternatives listed below and such act by the
                    Committee may not be revoked or rescinded by persons not
                    members of the Committee immediately prior to the Change of
                    Control:

                              1.   require that all outstanding options be
                         exercised on or before a specified date (before or
                         after such Change of Control) fixed by the Committee,
                         after which specified date all unexercised options
                         shall terminate,

                              2.   make such equitable adjustments to Incentives
                         then outstanding as the Committee deems appropriate to
                         reflect such Change of Control (provided, however, that
                         the Committee may determine in its sole discretion that
                         no adjustment is necessary), or

                              3.   provide that thereafter upon any exercise of
                         an option the participant shall be entitled to purchase
                         under such option, in lieu of the number of shares of
                         Common Stock then covered by such option, the number

                                      -12-

                         and class of shares of stock or other securities or
                         property (including, without limitation, cash) to which
                         the participant would have been entitled pursuant to
                         the terms of the agreement providing for the merger,
                         consolidation, asset sale, dissolution or other Change
                         of Control of the type described in Sections 10.11.A.3
                         and A.4 of the Plan, if, immediately prior to such
                         Change of Control, the participant had been the holder
                         of record of the number of shares of Common Stock then
                         covered by such options.

                    10.12. DEFINITION OF FAIR MARKET VALUE. Whenever "Fair
               Market Value" of Common Stock shall be determined for purposes of
               this Plan, it shall be determined as follows: (i) if the Common
               Stock is listed on an established stock exchange or any automated
               quotation system that provides sale quotations, the closing sale
               price for a share of the Common Stock on such exchange or
               quotation system on the applicable date; (ii) if the Common Stock
               is not listed on any exchange or quotation system, but bid and
               asked prices are quoted and published, the mean between the
               quoted bid and asked prices on the applicable date, and if bid
               and asked prices are not available on such day, on the next
               preceding day on which such prices were available; and (iii) if
               the Common Stock is not regularly quoted, the fair market value
               of a share of Common Stock on the applicable date as established
               by the Committee in good faith.

                    10.13  LOANS. In order to assist a participant in acquiring
               shares of Common Stock pursuant to an Incentive granted under the
               Plan, the Committee may authorize, subject to the provisions of
               Regulation G of the Board of Governors of the Federal Reserve
               System, at either the time of the grant of the Incentive, at the
               time of the acquisition of Common Stock pursuant to the
               Incentive, or at the time of the lapse of restrictions on shares
               of restricted stock granted under the Plan, the extension of a
               loan to the participant by the Company. The terms of any loans,
               including the interest rate, collateral and terms of repayment,
               will be subject to the discretion of the Committee. The maximum
               credit available hereunder shall be equal to the aggregate
               purchase price of the shares of Common Stock to be acquired
               pursuant to the Incentive plus the maximum tax liability that may
               be incurred in connection with the Incentive.

                    10.14 TAX BENEFIT RIGHTS. The Committee may grant a tax
               benefit right ("TBR") to a participant in the Plan on such terms
               as the Committee in its discretion shall determine. A TBR may be
               granted only with respect to an Incentive granted under the Plan
               and may be granted concurrently with or after the grant of the
               Incentive. A TBR shall entitle a participant to receive from the
               Company an amount in cash not to exceed the product of the
               ordinary income, if any, which the participant may realize as the
               result of the exercise of an option or the grant or vesting of
               restricted stock or an Other Stock-Based Award (including any
               income realized as a result of the related TBR) multiplied by the
               then applicable highest stated federal and state tax rate for
               individuals. The Committee shall determine all terms and
               provisions of the TBR granted hereunder.

                            STOCK OPTION AGREEMENT
                               FOR THE GRANT OF
                     NON-QUALIFIED STOCK OPTIONS UNDER THE
                          OMNI ENERGY SERVICES CORP.
                             STOCK INCENTIVE PLAN


     THIS AGREEMENT is entered into and effective as of __________, 1997, by and
between Omni Energy Services Corp., a Louisiana corporation (the "Company"), and
______________ (the "Optionee").

     WHEREAS Optionee is a key employee of the Company and the Company considers
it desirable and in its best interest that Optionee be given an inducement to
acquire a proprietary interest in the Company and an incentive to advance the
interests of the Company by possessing an option to purchase shares of the
common stock of the Company, $.01 par value per share (the "Common Stock") in
accordance with the Omni Energy Services Corp. Stock Incentive Plan (the
"Plan").

     NOW, THEREFORE, in consideration of the premises, it is agreed by and
between the parties as follows:


                                      I.

                                Grant of Option

     The Company hereby grants to Optionee effective as of the date hereof (the
"Date of Grant") the right, privilege and option to purchase ________ shares of
Common Stock (the "Option") at an exercise price equal to the initial public
offering price of the Common Stock (the "Exercise Price"). The grant of the
Option is subject to the issuance and sale of Common Stock registered with the
Securities and Exchange Commission on Form S-1 (Reg. No. 333-_______) in
connection with the Company's initial public offering of the Common Stock. The
Option shall be exercisable at the time specified in Section II below. The
Option is a non-qualified stock option and shall not be treated as an incentive
stock option under Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code").


                                      II.

                               Time of Exercise

     2.1  Subject to the provisions of the Plan and the other provisions of this
Section II, the Optionee shall be entitled to exercise the Option as follows:

                                      -1-
<PAGE>
 
          25%  of the total number of shares covered by
               the Option beginning one year following
               the Date of Grant;

          50%  of the total number of shares covered by
               the Option beginning two years following
               the Date of Grant, less any shares
               previously issued;

          75%  of the total number of shares covered by
               the Option beginning three years
               following the Date of Grant, less any
               shares previously issued; and

          100% of the total number of shares covered by
               the Option beginning four years
               following the Date of Grant, less any
               shares previously issued.

     2.2  During Optionee's lifetime, the Option may be exercised only by him or
his guardian if he has been declared incompetent. In the event of death, the
Option may be exercised as provided herein by the Optionee's estate or by the
person to whom such right devolves as a result of the Optionee's death.

     2.3  If an Optionee ceases to be an employee because of death or disability
within the meaning of Section 22(e)(3) of the Code ("Disability"), the Option
must be exercised, to the extent otherwise exercisable at the time of
termination of employment, within one year from the date on which the Optionee
ceases to be an employee, but in no event later than ten years following the
Date of Grant.

     2.4  If an Optionee ceases to be an employee because of retirement, the
Option must be exercised, to the extent otherwise exercisable at the time of
termination of employment, within 18 months from the date on which Optionee
ceases to be an employee, but in no event later than ten years following the
Date of Grant.

     2.5  If Optionee's employment is terminated, other than as a result of
death, disability or retirement, the Option must be exercised, to the extent
otherwise exercisable at the time of termination of employment, within three
months from the date on which Optionee ceases to be an employee, but in no event
later than ten years following the date of grant.

     2.6  The Option shall expire and may not be exercised later than ten years
following the Date of Grant.

                         Method of Exercise of Option

     3.1  Optionee may exercise all or a portion of the Option by delivering to
the Company a signed written notice of his intention to exercise the Option,
specifying therein the number of shares to be purchased. Upon receiving such
notice, and after the Company has received full payment of the Exercise Price,
the appropriate officer of the Company shall cause the transfer of title of the
shares purchased to Optionee on the Company's stock records and cause to be
issued to Optionee a stock certificate for the number of shares being acquired.
Optionee shall not have any rights as a shareholder until the stock certificate
is issued to him.

     3.2  The Option may be exercised by the payment of the Exercise Price in
cash, in shares of Common Stock held for six months or in a combination of cash
and shares of Common Stock held for six months. The Optionee may also pay the
Exercise Price by delivering a properly executed exercise notice together with
irrevocable instructions to a broker approved by the Compensation Committee
(with a copy to the Company) to promptly deliver to the Company the amount of
sale or loan proceeds to pay the Exercise Price.

                                      IV.

                      No Contract of Employment Intended

     Nothing in this Agreement shall confer upon Optionee any right to continue
in the employment of the Company or any of its subsidiaries, or to interfere in
any way with the right of the Company or any of its subsidiaries to terminate
Optionee's employment relationship with the Company or any of its subsidiaries
at any time.

                                      V.

                                Binding Effect

     This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, executors, administrators and
successors.

                              Non-Transferability

     The Option granted hereby may not be transferred, assigned, pledged or
hypothecated in any manner, by operation of law or otherwise, other than by
will, by the laws of descent and distribution or pursuant to a domestic
relations order, as defined in the Code, and shall not be subject to execution,
attachment or similar process.

<PAGE>
 
               6.   CONFIDENTIALITY AND NON-DISCLOSURE OF INFORMATION.  Employee
          recognizes, acknowledges and agrees that the names of the Company's
          customers and its pricing structure, processes, operations, marketing
          programs, sales techniques, designs, specifications and other trade
          secrets (collectively referred to herein as "Proprietary Information")
          are valuable, special and unique assets of the Company. Employee will
          not, during or after the term of Employee's employment, directly or
          indirectly, utilize for the benefit of any person, business,
          enterprise or entity other than Company, or disclose any portion or
          part of the Company's Proprietary Information to any person, firm,
          corporation, association or other entity for any reason or purpose
          whatsoever. Furthermore, it is agreed that all data, lists, papers,
          memoranda, documents, and all products of Employee's skill, resulting
          from Employee's employment herein, shall be and remain the sole and
          exclusive property of the Company, and Employee shall execute any and
          all agreements and instruments that may be necessary to evidence the
          Company's ownership of such property. In the event of a breach or
          threatened breach by the Employee of the provisions of this Section 6,
          the Company shall be entitled to an injunction restraining the
          Employee from breaching the terms of this Agreement. Nothing herein
          shall be construed as prohibiting the Company from pursuing any other
          remedy available to the Company for such breach or threatened breach,
          including the recovery of damages from the Employee.

               7.   COVENANT OF NON-COMPETITION.  For a period during Employee's
          employment and ending five (5) years after termination of Employee's
          employment under this Agreement (whether such termination occurs
          because of a breach of this Agreement by the Company or by Employee or
          because of a termination of this Agreement by Company or Employee):
          (a) the Employee will not, directly or indirectly, within any parish
          or municipality in Louisiana or in any other state or foreign
          jurisdiction in which customers of the Company are located or reside,
          solicit, induce or otherwise contact customers of the Company for the
          purpose of soliciting business from the Company's customers, or any
          other purpose whatsoever which is detrimental to the Company or its
          business; (b) the Employee will not, directly or indirectly, within
          any parish or municipality in Louisiana or in any other state or
          foreign jurisdiction in which Company engages in or has engaged in
          business, own, manage, operate, control, be employed by, consult with,
          participate in, or be connected in any manner with the ownership,
          management, operation or control of any business, enterprise, or
          entity (including a sole proprietorship of Employee) which: (i) owns,
          operates or controls any geophysical services business, which business
          includes but is not limited to the provision of seismic drilling and
          support services, the transportation of equipment used in connection
          with seismic drilling and support services, and the design and
          manufacture of such equipment, or (ii) owns, operates or controls any
          business which competes with the Company. In the event of any actual
          or threatened breach by the Employee of the provisions of this
          Agreement, Employee agrees that Company shall not have an adequate
          remedy at law and the Company shall be entitled to an injunction
          restraining the Employee from owning, managing, operating,
          controlling, being employed by, participating in, or being in any way
          so connected with any activity which is prohibited in this Section 7
          and/or the solicitation of any business on his behalf or on behalf of
          others from any customer. Nothing herein stated shall be construed as
          prohibiting Company from pursuing any other remedies available to the
          Company for such breach or threatened breach including the recovery of
          damages from the Employee.

               8.   PERMITTED BUSINESS.  The parties acknowledge that Employee
          has a fifty percent (50%) ownership interest in the stock of
          Birthright Investment Group, Inc. d/b/a Marsh Equipment Company, a
          Louisiana corporation ("Marsh Equipment"), which designs, manufactures
          and sells equipment that can be used to provide seismic drilling and
          support services. Notwithstanding the provisions of Section 7 of this
          Agreement, the Company acknowledges and agrees that Employee may
          continue to own the interest in Marsh Equipment set forth in this
          Section 8 without violating the non-competition restrictions and
          covenants contained in this Agreement.

               9.   COMPANY'S OPTION TO PURCHASE MARSH EQUIPMENT.  At any time
          during the term of this Agreement, the Company shall have the option
          to purchase all (but not less than all) of Employee's right, title and
          interest in and to the stock of Marsh Equipment for a purchase price
          of Twenty Thousand Dollars ($20,000) (the "Company's Option"). The
          Company's Option shall be exercisable by delivery of a written notice
          to the Employee. The closing date for the exercise of the Company's
          Option shall be as mutually agreed upon by the Company and the
          Employee, but shall not be later than thirty (30) days after delivery
          of the written notice referred to in this Section 9.

               10.  EMPLOYEE'S PUT OF MARSH EQUIPMENT.  At any time during the
          term of this Agreement, the Employee shall have the right to sell, and
          to require the Company to purchase all (but not less than all) of
          Employee's right, title and interest in and to the stock of Marsh
          Equipment for a purchase price of Twenty Thousand Dollars ($20,000)
          (the "Employee's Put"). The Employee's Put shall be exercisable by
          delivery of a written notice to the Company. The closing date for the
          exercise of the Employee's Put shall be as mutually agreed upon by the
          Company and the Employee, but shall not be later than thirty (30) days
          after delivery of the written notice referred to in this Section 10.

               11.  REFORMATION/SAVINGS CLAUSE.  The parties agree that if
          either the length of time or the geographical area of Employee's
          covenants contained herein are deemed too restrictive by any court of
          competent jurisdiction in any proceeding involving the validity of
          said covenants, then the court may reduce the offending restriction to
          the maximum restriction it deems reasonable under the circumstances so
          as to give the maximum permissible effect to the intentions of the
          parties as set forth herein, and the court may enforce such provisions
          as so reformed.

               12.  REMEDIES AND EQUITABLE PROVISIONS.  The following provisions
          shall apply in respect of Employee's covenants and agreements
          contained in this Agreement:

               (a)  Employee acknowledges and agrees that Employee's covenants
          contained in this Agreement are reasonable and necessary for the
          proper protection of Company and that the Employee's agreements herein
          not to compete with the Company shall not hinder Employee in obtaining
          gainful employment at the termination of this Agreement in the event
          Employee shall desire such employment.

                                       3
<PAGE>
 
               (b)  Employee acknowledges and agrees that Company does not have
          an adequate remedy at law for the breach or threatened breach of
          Employee's covenants contained in this Agreement and Employee
          therefore agrees that Company, in addition to any other remedy which
          may be available to it, shall be entitled to enforce Employee's
          covenants by injunction or other equitable means.

               (c)  The parties agree that if Company should institute
          litigation against Employee to enforce any provisions of this
          Agreement, then the prevailing party in such litigation shall be
          entitled to receive, in addition to any other relief awarded such
          party, reasonable attorneys' fees in respect of the prosecution or
          defense of such litigation.

               13.  NOTICES.  Any notice required or permitted to be given under
          this Agreement shall be sufficient if in writing, and if sent by
          certified mail

               If to Employee:  Allen R. Woodard
                                1902 Sevanne Road

               14.  WAIVER OF BREACH.  The waiver or nonenforcement by the
          Company of a breach of any provision of this Agreement by the Employee
          shall not operate or be construed as a waiver of any subsequent breach
          by the Employee.

               15.  ASSIGNMENT.  Employee acknowledges that the services to be
          rendered by him are unique and personal. Accordingly, Employee may not
          assign any of his rights or delegate any of his duties or obligations
          under this Agreement. The rights and obligations of Company under this
          Agreement shall inure to the benefit of and shall be binding upon the
          successors and assigns of Company.

               16.  SEVERABILITY.  Every provision of this Agreement is entitled
          to be severable. The parties agree that if any term or provision
          hereof is held to be illegal, invalid, against public policy or
          unenforceable for any reason whatsoever, such illegality or invalidity
          shall not affect the validity of the remainder to the Agreement, and
          the remaining provisions of this Agreement shall not be affected
          thereby.

               17.  AMENDMENTS.  No alterations, modifications, amendments or
          changes herein shall be effective or binding upon the parties unless
          the same shall have been agreed in writing by all the parties.

               18.  SECTION HEADINGS.  Section and other headings in this
          Agreement are for reference purposes only, and are in no way intended
          to describe, interpret, define or limit the scope or extent of any
          provision hereof.

               19.  COUNTERPART EXECUTION.  This Agreement may be executed by
          any number of counterparts with the same effect as if all parties
          hereto had signed the same document. All counterparts shall be
          construed together and shall constitute one agreement.

               20.  APPLICABLE LAW.  Company and Employee acknowledge and agree
          that the law of several states could, conceivably, apply to the terms
          of this Agreement. In order to provide certainty with respect to the
          construction, interpretation and enforcement of this Agreement, it is
          the intention of the parties that the internal laws of the State of
          Louisiana shall govern only the construction, interpretation, validity
          and enforcement of each term of the Agreement which relates to
          obligations which are intended to be performed or restrictions upon
          the activities or conduct of the parties within the State of
          Louisiana. The construction, interpretation, validity and enforcement
          of each term of the Agreement which relates to obligations to be
          performed or restrictions upon the activities or conduct of the
          parties outside of the State of Louisiana shall be governed by the law
          of the State of Texas. The parties to this Agreement have agreed to
          this bifurcated choice of law after careful consideration and
          reflection.

               21.  RIGHTS CUMULATIVE.  The rights of Company hereunder shall be
          cumulative and the enforcement by Company of any right shall not
          affect in any way the ability of Company to enforce any other right
          hereunder or any right or remedy of Company at law or in equity.

               22.  ENTIRE AGREEMENT.  This instrument contains the entire
          agreement of the parties and may not be changed orally but only by
          agreement in writing signed by the party against whom enforcement of
          any waiver, change, modification or discharge is sought.

               5.   TERMINATION.  This Agreement may be terminated at any time
          by the Company, without prior notice, for cause or for breach of any
          obligation of Employee to Company, and may also be terminated at any
          time by the Company, without prior notice, without cause; provided,
          however, that in the event this Agreement is terminated by the Company
          without cause, then the Company shall continue to pay the Employee the
          compensation as set forth in Section 2 hereof through June 30, 2000.
          For purposes of this Agreement, the Company shall have "Cause" for
          termination of Employee's employment hereunder upon the occurrence of
          any of the following: (i) the continued failure by Employee to
          substantially perform his duties hereunder in the manner and at the
          level as customarily performed by the general manager of aviation
          companies after demand for substantial performance is delivered by the
          Company that identifies the manner in which the Company believes
          Employee has not substantially performed his duties, (ii) the
          Employee's conviction of a felony, (iii) any acts of dishonesty or
          deceit by the Employee involving the Company's business or his
          performance of his duties hereunder, or (iv) a material breach of any
          fiduciary duty of loyalty owed to the Company by the Employee.

               6.   CONFIDENTIALITY AND NON-DISCLOSURE OF INFORMATION.  Employee
          recognizes, acknowledges and agrees that the names of the Company's
          customers and its pricing structure, processes, operations, marketing
          programs, sales techniques, designs, specifications and other trade
          secrets (collectively referred to herein as "Proprietary Information")
          are valuable, special and unique assets of the Company. Employee will
          not, during or after the term of Employee's employment hereunder,
          directly or indirectly, utilize for the benefit of any person,
          business, enterprise or entity other than Company or disclose any
          portion or part of the Company's Proprietary Information to any
          person, firm, corporation, association or other entity for any reason
          or purpose whatsoever. Furthermore, it is agreed that all data, lists,
          papers, memoranda, documents, and all products of Employee's skill,
          resulting from Employee's employment hereunder, shall be and remain
          the sole and exclusive property of the Company, and Employee shall
          execute any and all agreements and instruments that may be necessary
          to evidence the Company's ownership of such property. In the event of
          a breach or threatened breach by the Employee of the provisions of
          this Section 6, the Company shall be entitled to an injunction
          restraining the Employee from breaching the terms of this Agreement.
          Nothing herein shall be construed as prohibiting the Company from
          pursuing any other remedy available to the Company for such breach or
          threatened breach, including the recovery of damages from the
          Employee.

               7.   COVENANT OF NON-COMPETITION.  For the period beginning on
          the mutual execution of this Agreement and expiring two (2) years
          after the termination of Employee's employment under this Agreement,
          (a) the Employee will not, directly or indirectly, within any parish
          or municipality in Louisiana or in any other state or foreign
          jurisdiction in which customers of the Company are located or reside,
          solicit, induce or otherwise contact customers of the Company for the
          purpose of soliciting business from the Company's customers, or any
          other purpose whatsoever which is detrimental to the Company or its
          business; and (b) the Employee will not, directly or indirectly,
          within any parish or municipality in Louisiana or in any other state
          or foreign jurisdiction in which Company engages in or has engaged in
          business, own, manage, operate, control, be employed by, consult with,
          participate in, or be connected in any manner with the ownership,
          management,

                                       2
<PAGE>
 
          operation or control of any business, enterprise, or entity (including
          a sole proprietorship of Employee) which: (i) owns, operates or
          controls any geophysical services business, which business includes
          but is not limited to the provision of seismic drilling and support
          services, the transportation of equipment used in connection with
          seismic drilling and support services, and the design and manufacture
          of such equipment, or (ii) owns, operates or controls any aviation
          company which provides seismic drilling or support services or
          provides aircraft, pilots or other related equipment and services that
          are used in support of seismic drilling or surveying activities. In
          the event of any actual or threatened breach by the Employee of the
          provisions of this Agreement, Employee agrees that Company shall not
          have an adequate remedy at law and the Company shall be entitled to an
          injunction restraining the Employee from owning, managing, operating,
          controlling, being employed by, participating in, or being in any way
          so connected with any activity which is prohibited in this Section 7
          and/or the solicitation of any business on his behalf or on behalf of
          others from any customer. Nothing herein stated shall be construed as
          prohibiting Company from pursuing any other remedies available to the
          Company for such breach or threatened breach including the recovery of
          damages from the Employee.

               8.   REFORMATION/SAVINGS CLAUSE.  The parties agree that if
          either the length of time or the geographical area of Employee's
          covenants contained herein are deemed too restrictive by any court of
          competent jurisdiction in any proceeding involving the validity of
          said covenants, then the court may reduce the offending restriction to
          the maximum restriction it deems reasonable under the circumstances so
          as to give the maximum permissible effect to the intentions of the
          parties as set forth herein, and the court may enforce such provisions
          as so reformed.

               9.   REMEDIES AND EQUITABLE PROVISIONS.  The following provisions
          shall apply in respect of Employee's covenants and agreements
          contained in this Agreement:

               (a)  Employee acknowledges and agrees that Employee's covenants
          contained in this Agreement are reasonable and necessary for the
          proper protection of Company and that the Employee's agreements herein
          not to compete with the Company shall not hinder Employee in obtaining
          gainful employment at the termination of this Agreement in the event
          Employee shall desire such employment.

               (b)  Employee acknowledges and agrees that Company does not have
          an adequate remedy at law for the breach or threatened breach of
          Employee's covenants contained in this Agreement, and Employee
          therefore agrees that Company, in addition to any other remedy which
          may be available to it, shall be entitled to enforce Employee's
          covenants by injunction or other equitable means.

               (c)  The parties agree that if Company should institute
          litigation against Employee to enforce any provisions of this
          Agreement, then the prevailing party in such litigation shall be
          entitled to receive, in addition to any other relief awarded such
          party, reasonable attorneys' fees in respect of the prosecution or
          defense of such litigation.

               10.  NOTICES.  Any notice required or permitted to be given under
          this Agreement shall be sufficient if in writing, and if sent by
          certified mail

                                P.O. Box 5409

               11.  WAIVER OF BREACH.  The waiver or nonenforcement by the
          Company of a breach of any provision of this Agreement by the Employee
          shall not operate or be construed as a waiver of any subsequent breach
          by the Employee.

               12.  ASSIGNMENT.  Employee acknowledges that the services to be
          rendered by him are unique and personal. Accordingly, Employee may not
          assign any of his rights or delegate any of his duties or obligations
          under this Agreement. The rights and obligations of Company under this
          Agreement shall inure to the benefit of and shall be binding upon the
          successors and assigns of Company.

               13.  SEVERABILITY.  Every provision of this Agreement is entitled
          to be severable. The parties agree that if any term or provision
          hereof is held to be illegal, invalid, against public policy or
          unenforceable for any reason whatsoever, such illegality or invalidity
          shall not affect the validity of the remainder to the Agreement, and
          the remaining provisions of this Agreement shall not be affected
          thereby.

               14.  AMENDMENTS.  No alterations, modifications, amendments or
          changes herein shall be effective or binding upon the parties unless
          the same shall have been agreed in writing by all the parties.

               15.  SECTION  HEADINGS.  Section and other headings in this
          Agreement are for reference purposes only, and are in no way intended
          to describe, interpret, define or limit the scope or extent of any
          provision hereof.

               16.  COUNTERPART EXECUTION.  This Agreement may be executed by
          any number of counterparts with the same effect as if all parties
          hereto had signed the same document. All counterparts shall be
          construed together and shall constitute one agreement.

               17.  APPLICABLE LAW.  Company and Employee acknowledge and agree
          that the law of several states could, conceivably, apply to the terms
          of this Agreement. In order to provide certainty with respect to the
          construction, interpretation and enforcement of this Agreement, it is
          the intention of the parties that the internal laws of the State of
          Louisiana shall govern only the construction,

                                       4
<PAGE>
 
          interpretation, validity and enforcement of each term of the Agreement
          which relates to obligations which are intended to be performed or
          restrictions upon the activities or conduct of the parties within the
          State of Louisiana. The construction, interpretation, validity and
          enforcement of each term of the Agreement which relates to obligations
          to be performed or restrictions upon the activities or conduct of the
          parties outside of the State of Louisiana shall be governed by the law
          of the State of Texas. The parties to this Agreement have agreed to
          this bifurcated choice of law after careful consideration and
          reflection.

               18.  RIGHTS CUMULATIVE.  The rights of Company hereunder shall be
          cumulative and the enforcement by Company of any right shall not
          affect in any way the ability of Company to enforce any other right
          hereunder or any right or remedy of Company at law or in equity.

               19.  ENTIRE AGREEMENT.  This instrument contains the entire
          agreement of the parties and may not be changed orally but only by
          agreement in writing signed by the party against whom enforcement of
          any waiver, change, modification or discharge is sought.

               IN WITNESS WHEREOF, the Company has caused this Agreement to be
          executed by its duly authorized managers, and the Employee has
          hereunto set his hand as of the day and year first above written.

          written consent of the Company, directly or indirectly, in any

          pursuing any other remedies available to the Company for such breach
          or threatened breach including the recovery of damages from Omni
          Corporation or any of the Shareholders.

               2.   COVENANT OF NON-COMPETITION. For a period of seven (7) years
          beginning with the effective date of this Agreement, (a) Omni
          Corporation and each of the Shareholders will not, directly or
          indirectly, within any parish or municipality in Louisiana or in any
          other state or foreign jurisdiction in which customers of the Company
          are located or reside, solicit, induce or otherwise contact customers
          of the Company for the purpose of soliciting business from the
          Company's customers or for any other purpose whatsoever which is
          detrimental to the Company or its business; and (b) Omni Corporation
          and each of the Shareholders will not, directly or indirectly, within
          any parish or municipality in Louisiana or in any other state or
          foreign jurisdiction in which the Company engages in or has engaged in
          business, own, manage, operate, control, be employed by, consult with,
          participate in, or be connected in any manner with the ownership,
          management, operation or control of any business, enterprise, or
          entity (including a sole proprietorship of any of the Shareholders or
          a partnership including any of the Shareholders) which: (i) owns,
          operates or controls any geophysical services business, which business
          includes but is not limited to the provision of seismic drilling and
          support services, the transportation of equipment used in connection
          with seismic drilling and support services, and the design and
          manufacture of such equipment, or (ii) owns, operates or controls any
          business which competes with the Company. In the event of any actual
          or threatened breach by Omni Corporation or any of the Shareholders of
          the provisions of this Agreement, Omni Corporation and each of the
          Shareholders agree that the Company shall not have an adequate remedy
          at law, and the Company shall be entitled to an injunction restraining
          Omni Corporation and/or any or all of the Shareholders from owning,
          managing, operating, controlling, being employed by, participating in,
          or being in any way so connected with any activity which is prohibited
          in this Section 2 and/or the solicitation of any business on his or
          its behalf or on behalf of others from any customer. Nothing herein
          stated shall be construed as prohibiting the Company from pursuing any
          other remedies available to the Company for such breach or threatened
          breach including the recovery of damages from Omni Corporation or any
          of the Shareholders.

               3.   PERMITTED BUSINESS. The parties acknowledge that one of the
          Shareholders, David Jeansonne, owns and operates American Aviation,
          Inc., a Louisiana corporation ("American Aviation"), which utilizes
          its fleet of helicopters to provide seismic drilling and support
          services. Notwithstanding the provisions of Section 2 of this
          Agreement, the Company acknowledges and agrees that David Jeansonne
          may continue to own and operate American Aviation as set forth in this
          Section 2 without violating the non-competition restrictions and
          covenants contained in this Agreement.

               4.   REMEDIES AND EQUITABLE PROVISIONS. The following provisions
          shall apply in respect of the covenants and agreements of Omni
          Corporation and the Shareholders contained in this Agreement:

               (a)  Omni Corporation and each of the Shareholders acknowledge
          and agree that the covenants and restrictions contained in this
          Agreement are reasonable and necessary for the proper protection of
          the legitimate interests of the Company.

               (b)  Omni Corporation and each of the Shareholders further
          acknowledge and agree that any breach or threatened breach of any
          agreement contained in Sections 1 and 2 above will cause such damage
          to the Company as to be irreparable and which would be difficult to
          ascertain and for which the Company does not have an adequate remedy
          at law, and accordingly, Omni Corporation and each of the Shareholders
          agree that the Company, in addition to any other remedy which may be
          available to it, shall be entitled to enforce the covenants of Omni
          Corporation and the Shareholders by injunction or other equitable
          means. Nothing herein shall be construed as prohibiting the Company
          from pursuing any other remedy available to the Company for such
          breach or threatened breach, including the recovery of damages from
          Omni Corporation or any of the Shareholders.

               (c)  The parties agree that if Company should institute
          litigation against Omni Corporation or any of the Shareholders to
          enforce any provisions of this Agreement, then the prevailing party in
          such litigation shall be entitled to receive, in addition to any other
          relief awarded such party, reasonable attorneys' fees in respect of
          the prosecution or defense of such litigation.

               5.   REFORMATION/SAVINGS CLAUSE. The parties agree that if either
          the length of time or the geographical area of the covenants of Omni
          Corporation and the Shareholders contained herein are deemed too
          restrictive by any court of competent jurisdiction in any proceeding
          involving the validity of said covenants, then the court may reduce
          the offending restriction to the maximum restriction it deems
          reasonable under the circumstances so as to give the maximum
          permissible effect to the intentions of the parties as set forth
          herein, and the court may enforce such provisions as so reformed.

               6.   WAIVER OF BREACH. The waiver or nonenforcement by the
          Company of a breach of any provision of this Agreement by Omni
          Corporation or any of the Shareholders shall not operate or be
          construed as a waiver of any subsequent breach by Omni Corporation or
          the Shareholders.

                                       3

               7.   SEVERABILITY. Every provision of this Agreement is entitled
          to be severable. The parties agree that if any term or provision of
          the Agreement is held to be illegal, invalid, against public policy or
          unenforceable for any reason whatsoever, such illegality or invalidity
          shall not affect the validity of the remainder to the Agreement, and
          the remaining provisions of this Agreement shall not be affected
          thereby.

               8.   AMENDMENTS. No alterations, modifications, amendments or
          changes herein shall be effective or binding upon the parties unless
          the same shall have been agreed in writing by all the parties.

               9.   SECTION HEADINGs. Section and other headings in this
          Agreement are for reference purposes only, and are in no way intended
          to describe, interpret, define or limit the scope or extent of any
          provision hereof.

               10.  COUNTERPART EXECUTION. This Agreement may be executed by any
          number of counterparts with the same effect as if all parties hereto
          had signed the same document. All counterparts shall be construed
          together and shall constitute one agreement.

               11.  APPLICABLE LAW. The Company, Omni Corporation and each of
          the Shareholders acknowledge and agree that under applicable conflicts
          of laws rules, the law of several states could, conceivably, apply to
          the terms of this Agreement. In order to provide certainty with
          respect to the construction, interpretation and enforcement of this
          Agreement, it is the intention of the parties that the internal laws
          of the State of Missouri shall govern the construction,
          interpretation, validity and enforcement of each and every term of
          this Agreement. The parties to this Agreement have chosen the law of
          the State of Missouri after careful consideration and reflection upon
          the desirability of the stability and certainty of result which will
          occur if the internal laws of the State of Missouri are chosen in the
          manner described to govern the construction, interpretation,
          enforcement, termination and validity of the rights and duties of the
          parties under this Agreement.

               12.  RIGHTS CUMULATIVE. The rights of Company hereunder shall be
          cumulative, and the enforcement by Company of any right shall not
          affect in any way the ability of Company to enforce any other right
          hereunder or any right or remedy of Company at law or in equity.

               13.  ENTIRE AGREEMENT. This instrument contains the entire
          agreement of the parties and may not be changed orally but only by
          agreement in writing signed by the party against whom enforcement of
          any waiver, change, modification or discharge is sought.

                              AND RICHARD PATRICK MORRIS

                    CONFIDENTIALITY AND NON-COMPETITION AGREEMENT


               THIS CONFIDENTIALITY AND NON-COMPETITION AGREEMENT (hereinafter
          referred to as the "Agreement") is made and entered into on the 6th
          day of August, 1997, but effective as of July 1, 1997, by and between

          ("Omni"), AMERICAN AVIATION L.L.C., a single-member limited liability
          company owned 100% by the Company ("AA") (Omni and AA being
          hereinafter collectively referred to as the "Company"), AMERICAN
          AVIATION INCORPORATED, a Louisiana corporation ("American"), and DAVID
          JEANSONNE ("Jeansonne") and RICHARD PATRICK MORRIS ("Morris"), each a
          resident of the State of Louisiana (Jeansonne and Morris being
          hereinafter collectively referred to as the "Shareholders").

               WHEREAS, pursuant to the Intangible Asset Purchase Agreement (the
          "Purchase Agreement") and the Exchange Agreement (the "Exchange
          Agreement") both of even date herewith, by and among the Company and
          AA, the Company acquired all of the Assets of the Business (as those
          terms are defined in the Purchase Agreement and the Exchange
          Agreement) of American;

               WHEREAS, the agreements of American and the Shareholders
          hereunder are an important aspect of the Purchase Agreement and the
          Exchange Agreement, and the Company would not consummate the Purchase
          Agreement and the Exchange Agreement absent the execution and delivery
          of this Agreement, including the covenants set forth in Sections 1 and
          2 of this Agreement; and

               WHEREAS, the Company considers the goodwill of the Business
          acquired by the Company pursuant to the Purchase Agreement to be an
          essential component of the business and operations of American, and
          the Company and American desire the Company to continue to have and to
          enjoy the full benefit of said goodwill;

               NOW, THEREFORE, in consideration of the mutual promises,
          covenants and agreements herein contained, the receipt and legal
          sufficiency of which are hereby acknowledged, the parties hereto agree
          as follows:

               1.   CONFIDENTIALITY AND NON-DISCLOSURE OF INFORMATION. American
          and each of the Shareholders hereby recognize, acknowledge and agree
          that confidential information of any kind, nature or description
          concerning any matters affecting or relating to the Business (as that

<PAGE>
 
          defined in the Purchase Agreement and the Exchange Agreement),
          including but not limited to the names of customers, pricing
          structure, processes, operations, marketing programs, sales
          techniques, designs, specifications and other trade secrets
          (collectively referred to herein as "Proprietary Information"), are
          valuable, special and unique assets of the Company. American and each
          of its Shareholders agrees that he (or it, in the case of American)
          will not, without the prior written consent of the Company, directly
          or indirectly, in any individual or representative capacity whatsoever
          (a) utilize for the benefit of any person, business, enterprise or
          entity other than Company or (b) disclose any portion or part of the
          Company's Proprietary Information to any person, firm, corporation,
          association or other entity for any reason or purpose whatsoever. In
          the event of any actual or threatened breach by American or any of the
          Shareholders of the provisions of this Section 1, American and each of
          the Shareholders agree that the Company shall not have an adequate
          remedy at law, and the Company shall be entitled to an injunction
          restraining American and/or any or all of the Shareholders from
          breaching the provisions of this Agreement. Nothing herein stated
          shall be construed as prohibiting the Company from pursuing any other
          remedies available to the Company for such breach or threatened breach
          including the recovery of damages from American or any of the
          Shareholders.

               2.   COVENANT OF NON-COMPETITION. For a period of six (6) years
          beginning with the effective date of this Agreement, (a) American and
          each of the Shareholders will not, directly or indirectly, within any
          parish or municipality in Louisiana or in any other state or foreign
          jurisdiction in which customers of the Company are located or reside,
          solicit, induce or otherwise contact customers of the Company for the
          purpose of soliciting business from the Company's customers or for any
          other purpose whatsoever which is detrimental to the Company or its
          business; and (b) American and Jeansonne will not, directly or
          indirectly, within any parish or municipality in Louisiana or in any
          other state or foreign jurisdiction in which the Company engages in or
          has engaged in business, own, manage, operate, control, be employed
          by, consult with, participate in, or be connected in any manner with
          the ownership, management, operation or control of any business,
          enterprise, or entity (including a sole proprietorship of Jeansonne or
          a partnership including Jeansonne) which: (i) owns, operates or
          controls any geophysical services business, which business includes
          but is not limited to the provision of seismic drilling and support
          services, the transportation of equipment used in connection with
          seismic drilling and support services, and the design and manufacture
          of such equipment, or (ii) owns, operates or controls any aviation
          company, or (iii) owns, operates or controls any business which
          competes with the Company. For a period of three (3) years beginning
          with the effective date of this Agreement, Morris will not, directly
          or indirectly, within any parish or municipality in Louisiana or in
          any other state or foreign jurisdiction in which the Company engages
          in or has engaged in business, own, manage, operate, control, be
          employed by, consult with, participate in, or be connected in any
          manner with the ownership, management, operation or control of any
          business, enterprise, or entity (including a sole proprietorship of
          Morris or a partnership including Morris) which: (i) owns, operates or
          controls any geophysical services business, which business includes
          but is not limited to the provision of seismic drilling and support
          services, the transportation of equipment used in connection with
          seismic drilling and support services, and the design and manufacture
          of such equipment, or (ii) owns, operates or controls any aviation
          company, or (iii) owns, operates or controls any business which
          competes with the

                                       2
<PAGE>
 
          Company. In the event of any actual or threatened breach by American
          or any of the Shareholders of the provisions of this Agreement,
          American and each of the Shareholders agree that the Company shall not
          have an adequate remedy at law, and the Company shall be entitled to
          an injunction restraining American and/or any or all of the
          Shareholders from owning, managing, operating, controlling, being
          employed by, participating in, or being in any way so connected with
          any activity which is prohibited in this Section 2 and/or the
          solicitation of any business on his or its behalf or on behalf of
          others from any customer. Nothing herein stated shall be construed as
          prohibiting the Company from pursuing any other remedies available to
          the Company for such breach or threatened breach including the
          recovery of damages from American or any of the Shareholders.

               3.   REMEDIES AND EQUITABLE PROVISIONS. The following provisions
          shall apply in respect of the covenants and agreements of American and
          the Shareholders contained in this Agreement:

               (a)  American and each of the Shareholders acknowledge and agree
          that the covenants and restrictions contained in this Agreement are
          reasonable and necessary for the proper protection of the legitimate
          interests of the Company.

               (b)  American and each of the Shareholders further acknowledge
          and agree that any breach or threatened breach of any agreement
          contained in Sections 1 and 2 above will cause such damage to the
          Company as to be irreparable and which would be difficult to ascertain
          and for which the Company does not have an adequate remedy at law, and
          accordingly, American and each of the Shareholders agree that the
          Company, in addition to any other remedy which may be available to it,
          shall be entitled to enforce the covenants of American and the
          Shareholders by injunction or other equitable means. Nothing herein
          shall be construed as prohibiting the Company from pursuing any other
          remedy available to the Company for such breach or threatened breach,
          including the recovery of damages from American or any of the
          Shareholders.

               (c)  The parties agree that if Company should institute
          litigation against American or any of the Shareholders to enforce any
          provisions of this Agreement, then the prevailing party in such
          litigation shall be entitled to receive, in addition to any other
          relief awarded such party, reasonable attorneys' fees in respect of
          the prosecution or defense of such litigation.

               4.   REFORMATION/SAVINGS CLAUSE. The parties agree that if either
          the length of time or the geographical area of the covenants of
          American and the Shareholders contained herein are deemed too
          restrictive by any court of competent jurisdiction in any proceeding
          involving the validity of said covenants, then the court may reduce
          the offending restriction to the maximum restriction it deems
          reasonable under the circumstances so as to give the maximum
          permissible effect to the intentions of the parties as set forth

               5.   WAIVER OF BREACH. The waiver or nonenforcement by the
          Company of a breach of any provision of this Agreement by American or
          any of the Shareholders shall not operate or be construed as a waiver
          of any subsequent breach by American or the Shareholders.

               6.   SEVERABILITY. Every provision of this Agreement is entitled
          to be severable. The parties agree that if any term or provision of
          the Agreement is held to be illegal, invalid, against public policy or
          unenforceable for any reason whatsoever, such illegality or invalidity
          shall not affect the validity of the remainder to the Agreement, and
          the remaining provisions of this Agreement shall not be affected
          thereby.

               7.   AMENDMENTS. No alterations, modifications, amendments or
          changes herein shall be effective or binding upon the parties unless
          the same shall have been agreed in writing by all the parties.

               8.   SECTION HEADINGS. Section and other headings in this
          Agreement are for reference purposes only, and are in no way intended

               9.   COUNTERPART EXECUTION. This Agreement may be executed by any
          number of counterparts with the same effect as if all parties hereto
          had signed the same document. All counterparts shall be construed
          together and shall constitute one agreement.

               10.  APPLICABLE LAW. The Company, American and each of the
          Shareholders acknowledge and agree that under applicable conflicts of
          laws rules, the law of several states could, conceivably, apply to the
          terms of this Agreement. In order to provide certainty with respect to
          the construction, interpretation and enforcement of this Agreement, it
          is the intention of the parties that the internal laws of the State of
          Missouri shall govern the construction, interpretation, validity and
          enforcement of each and every term of this Agreement. The parties to
          this Agreement have chosen the law of the State of Missouri after
          careful consideration and reflection upon the desirability of the
          stability and certainty of result which will occur if the internal
          laws of the State of Missouri are chosen in the manner described to
          govern the construction, interpretation, enforcement, termination and
          validity of the rights and duties of the parties under this Agreement.

               11.  RIGHTS CUMULATIVE. The rights of Company hereunder shall be
          cumulative, and the enforcement by Company of any right shall not
          affect in any way the ability of Company to enforce any other right
          hereunder or any right or remedy of Company at law or in equity.

               12.  ENTIRE AGREEMENT. This instrument contains the entire
          agreement of the parties and may not be changed orally but only by
          agreement in writing signed by the party against whom enforcement of
          any waiver, change, modification or discharge is sought.

                               OMNI GEOPHYSICAL, L.L.C.
                                         AND
                                     DAVID CRAYS


                                   OPTION AGREEMENT


               THIS OPTION AGREEMENT (the "Option Agreement"or the "Agreement")
          is made and entered into on the 24th day of April, 1997 by and between
          OMNI GEOPHYSICAL, L.L.C., a Louisiana limited liability company
          ("Omni"), and DAVID CRAYS ("Crays").

                                 W I T N E S S E T H:

               WHEREAS, Omni desires to employ Crays as a Vice President and its
          Chief Financial Officer; and

               WHEREAS, in order to attract and retain Crays as its Chief
          Financial Officer, Omni is willing to grant Crays options to acquire
          516 of its Common Units upon the terms and conditions described
          herein.

               NOW, THEREFORE, in consideration of the mutual covenants set
          forth herein and for other good and valuable consideration, the
          receipt and legal sufficiency of which is hereby acknowledged, Crays
          and Omni hereby promise, covenant and agree as follows:

               1.   GRANT OF OPTION. Omni hereby irrevocably grants to Crays the
          right and option (the "Option") to purchase 516 of its Common Units
          (the "Common Units") on the terms and conditions herein set forth. As
          of the date of this Agreement, there are 103,263 Common Units
          outstanding.

               2.   OPTION PRICE. The purchase price for each Common Unit
          subject to the Option shall be Two Hundred Forty-Two and 25/100
          Dollars ($242.25) per Common Unit.

               3.   TERM OF OPTION; TRANSFERABILITY. The term of the Option
          shall be from the date of this Agreement through and including April
          30, 2007. The right to purchase Common Units under the Option shall
          vest and become effective as described in Section 5 of this Option
          Agreement. Crays shall not have any rights of a member of Omni with
          respect to the Common Units subject to this Option until the option is
          exercised and the sale of the Common Units subject to the Option is
          closed as provided herein. The Option and all of Crays' rights herein
          are nontransferable. The Option and the right to acquire Common Units
          pursuant to the Option shall be completely forfeited if Crays attempts
          or actually transfers, or otherwise disposes of the Option in
          contravention of Section 8 of this Option Agreement.

               4.   METHOD OF EXERCISING OPTION. Subject to the terms and
          conditions of this Agreement, the Option may be exercised by written
          notice to Omni, at P.O. Box 3761, Lafayette, Louisiana 70502. Such
          written notice shall state the election of Crays to exercise the
          Option, shall set forth the number of Common Units he wishes to
          purchase pursuant to the Option and shall be considered to be given by
          Crays for purposes of this Option Agreement when such notice is
          deposited in the United States mail, certified mail, return receipt
          requested, with postage prepaid, to the address described above. Such
          written notice shall fix a closing date which is not more than thirty
          (30) days from the date such notice shall be given by Crays for the
          payment of the full purchase price of any Common Units being acquired
          pursuant to the exercise of the Option at a closing of the transaction
          at Omni's principal offices at that time. Payment of such purchase
          price shall be made by cashier's check or certified check payable to
          the order of Omni or in immediately available funds. At the closing of
          the transaction, Omni agrees to execute and, if deemed necessary by
          Omni's counsel, to cause each of its members to execute, an amendment
          to its Operating Agreement in order to effect the transfer of the
          acquired Common Units to Crays.

               5.   VESTING. The Options shall vest and become fully earned and
          nonforfeitable during the period commencing with the date of this
          Option Agreement and ending on the third (3rd) anniversary of the date
          of this Agreement (the "Vesting Period") as described in this Section
          5. Notwithstanding any other provision of this Agreement, unless Crays
          should remain in the continuous employ of Omni during the Vesting
          Period, then the Option shall be forfeited, and Crays' right to
          acquire Common Units under the Option shall be null and void except to
          the extent that such rights under the Option have vested as provided
          in this Section 5.

                    (a)  If Crays ceases to be employed within the first year of
          the Vesting Period, none of his rights under the Option shall be
          vested, and he shall have no right to acquire Common Units of Omni;

                    (b)  If Crays ceases to be employed within the second year
          of the Vesting Period (the period after the first anniversary but
          prior to the second anniversary of this Option Agreement), one-third
          of his rights under the Option shall be vested, and he shall have the
          right to acquire 172 Common Units of Omni;

                    (c)  If Crays ceases to be employed within the third year of
          the Vesting Period (the period after the second anniversary but prior
          to the third anniversary of this Option Agreement), two-thirds of his
          rights under the Option shall be vested, and he shall have the right
          to acquire an additional 172 Common Units of Omni, for a total of 344
          Common Units of Omni;

                    (d)  If Crays remains in the continuous employ of the
          Company from the date of this Option Agreement through the end of the
          Vesting Period, all of his rights under the Option shall be vested,
          and he shall have the right to acquire an additional 172 Common Units
          of Omni, for a total of 516 Common Units of Omni.

                                       2
<PAGE>
 
                    (e)  If Crays' employment is terminated during the Vesting
          Period (i) by Omni without Cause or (ii) by Crays for Good Reason, as
          the terms "Cause" and "Good Reason", as applicable, are defined in the
          Employment Agreement dated of even date herewith between Omni and
          Crays (the "Employment Agreement"), the Option shall become
          immediately exercisable in full for a period of one year after
          termination of employment, after which time period the Option shall
          terminate.

                    (f)  If there is a change in control of Omni, as "Change in
          Control of the Company" is defined in the Employment Agreement, the
          Option shall become immediately exercisable in full for a period of
          one year after termination of employment, after which time period the
          Option shall terminate.

               6.   RIGHTS RELATED TO OPTION. The Option constitutes the right
          to acquire Common Units of Omni, as such Common Units are more fully
          described in Omni's Operating Agreement, or any security, instrument,
          property, or amount of consideration into which Common Units of Omni
          may be exchanged by reason of any merger, consolidation,
          recapitalization, reorganization or other transaction. The Option does
          not currently constitute equity in Omni, and Crays shall not be
          entitled to vote with the members of Omni on matters on which the
          members are entitled to vote as a result of the grant of the Option
          until such time as the Option is exercised and Crays acquires Common
          Units.

               7.   DUE AUTHORIZATION. The sale of Common Units of Omni pursuant
          to the exercise of this Option Agreement has been duly authorized by
          all necessary action of Omni. All members of Omni have consented to
          the issuance of any Common Units pursuant to the exercise of the
          Option, which consent shall be considered to be a consent for all
          purposes of Section 7 of the Omni Operating Agreement.

               8.   RESTRICTION ON TRANSFERABILITY OF OPTION. The Option is not
          assignable. Crays shall not transfer, convey, sell, assign, dispose
          of, pledge or otherwise convey the Option or any rights thereunder
          other than transfers by will or the laws of descent and distribution.
          Any such attempted disposition shall cause an immediate cancellation
          of the Option and forfeiture of any and all rights to acquire Common
          Units under the Option.

               9.   RESTRICTION ON TRANSFERABILITY OF COMMON UNITS. Both during
          and after the Vesting Period, the Common Units acquired as a result of
          exercise of the Option shall be subject to all transfer, admission and
          other restrictions and conditions contained in Omni's Operating
          Agreement. Any certificate representing Common Units shall bear a
          legend setting forth the restrictions on transfer contained in Omni's
          Operating Agreement. Crays shall not transfer, convey, sell, assign,
          dispose of, pledge or otherwise convey any Common Units acquired as a
          result of exercise of the Option except as provided in Omni's
          Operating Agreement. Any transferee of the Common Units shall agree to
          be bound by the terms and conditions of Omni's Operating Agreement.
          Any attempted disposition of the Common Units in contravention of this
          section shall be null and void.

               10.  RESTRICTION ON TRANSFERABILITY RELATED TO SECURITIES LAW.
          Omni shall have the right to restrict any transfer of the Option or
          the Common Units acquired as a result of exercise of the Option during
          any such period as may be necessary or advisable to comply with the
          Securities Exchange Act of 1934, as amended. Neither the Option nor
          the Common Units acquired as a result of exercise of the Option have
          been nor will be registered under the Securities Act of 1933, and
          Crays shall not transfer, convey, sell, assign, dispose of, pledge or
          otherwise convey the Option or any Common Units acquired as a result
          of exercise of the Option unless (i) such Option or Common Units have
          been registered under the Act or (ii) an exemption from the
          registration provisions of the Act is applicable to Crays' proposed
          sale, assignment, pledge, disposition or transfer of such Option or
          Common Units.

               11.  BINDING EFFECT. This Agreement shall be binding upon and
          inure to the benefit of the parties hereto and their respective heirs,
          legal representatives, successors and assigns.

          interpreted and enforced under and in accordance with the internal
          laws of the State of Louisiana.

          request of the other party, do, perform, execute, acknowledge and
          deliver all such acts, deeds, assignments, transfers, conveyances,
          powers of attorney, certificates and assurances as may be reasonably
          required to consummate the transactions contemplated hereby.

               15.  NO WAIVERS OR MODIFICATION. No waivers or modifications of
          any provisions of this Agreement shall be valid or binding unless in
          writing and executed by all of the parties hereto.

          multiple counterparts and all counterparts shall be considered to be
          an original and enforceable as such.

          agreement between the parties and supersedes all prior agreements,
