ITEM 1. BUSINESS.

OVERVIEW

     Grant Geophysical, Inc., a Delaware corporation (together with its
subsidiaries, "Grant," or the "Company"), is a leading provider of seismic data
acquisition services in land and transition zone environments in selected
markets, including the United States and Canada. Grant also provides seismic
data acquisition services in Latin America, the Middle East and the Far East.
Through its predecessors, including GGI Liquidating Corporation ("GGI"), and its
acquired subsidiary, Solid State Geophysical, Inc. ("Solid State"), together
with their respective subsidiaries, the Company has participated in the seismic
data acquisition services business in the United States and Latin America since
the 1940s, the Far East since the 1960s and Canada since the 1970s. The Company
has conducted operations in each of these markets, as well as in the Middle
East, in the past three years. The Company's seismic data acquisition services
typically are provided on an exclusive contract basis to domestic and
international oil and gas companies and seismic data marketing companies. Grant
also provides seismic data processing services through offices located in Dallas
and Houston, Texas.

     The Company utilizes sophisticated equipment to perform specialized 3D and
2D seismic surveys. All of the Company's seismic data acquisition crews are
capable of performing surveys in land environments and two are equipped to
perform surveys in transition zone environments. Transition zone environments
are swamps, marshes and shallow water areas that require specialized equipment
and must be surveyed with minimal disruption to the natural environment.

     The market for seismic land acquisition, both domestically and in certain
international regions, remains significantly depressed. Capital spending by oil
and gas companies on seismic data acquisition and processing has substantially
decreased from levels experienced in the past several years. The Company's
global seismic crew count decreased from an average of 18 to 20 during 1998 to
an average of 10 to 12 during 1999. As of March 24, 2000, the Company had nine
active crews. As a result, the Company 1999 operating results were materially
adversely affected.

     As of March 24, 2000, the Company was operating or mobilizing a total of
two crews in the United States, one crew in Latin America, five crews in Canada
and one crew in the Far East. For the twelve months ended December 31, 1999, the
Company's total revenues were $66.0 million, with approximately 48.9% from the
United States, 22.8% from Latin America, 11.4% from the Far East and 17.0% from
Canada.

     Grant's principal executive office is located at 16850 Park Row, Houston,
Texas 77084 and its telephone number is 281-398-9503.

THE INDUSTRY

     Oil and gas companies regularly use seismic data acquisition services to
image and identify underground geological structures likely to trap
hydrocarbons, both to aid in the exploration for and development of new
hydrocarbon reservoirs and to enhance production from existing reservoirs.
Seismic data has been used in the exploration for oil and gas since the late
1920s.

     Seismic data acquisition services companies acquire seismic data in land
and transition zone environments by deploying thousands of seismic sensors,
called geophones, over a portion of the area to be covered by the survey. An
energy source, such as a small explosive charge or mechanical vibrating unit, is
used to generate seismic energy that moves through the earth's subsurface and is
reflected by various underlying rock layers to the surface, where it is detected
by the geophones. As many as eight geophone strings are connected to a field
recording box, which collects the seismic data from those geophones. The
electrical output of each geophone string becomes the electrical input for one
recording channel, or "trace," of seismic data. Once the geophones and field
recording boxes are deployed over a portion of the survey area, an energy source
is activated, the reflected seismic energy is detected by the geophones, and the
signals from the geophones are collected and digitized by the field recording
boxes. These boxes in turn transmit the seismic data by cable,

                                        1
<PAGE>   4

radio telemetry or through hand-held data collection units to a central
recording system. The geophones and field recording boxes from one end of the
single recording line in the case of 2D seismic data, or an area of multiple
recording lines in the case of 3D seismic data, are then removed and relocated
elsewhere in the survey area. The seismic energy source is again activated and
the entire process is repeated, moving a few hundred feet at a time, until the
entire survey area is covered.

     Historically, the acquisition of 2D seismic data was the principal seismic
data acquisition technique. However, with the advancement and miniaturization of
seismic data recording equipment and the improvement of computer technology in
the past ten years, high-density surveys, or 3D seismic data, which provide a
much more comprehensive subsurface image, have become the industry standard.
Recent technical advances in seismic data acquisition and computer processing
have also resulted in the acquisition of higher-resolution surveys using
three-component geophones, known as 3C-3D.

LAND AND TRANSITION ZONE SEISMIC DATA ACQUISITION

     A land or transition zone seismic data acquisition crew typically consists
of a surveying crew that lays out the lines to be recorded and marks the sites
for energy source or geophone placement and equipment location, an explosives or
mechanical vibrating or compressed air unit crew, and a recording crew that lays
out the geophones and field recording boxes, directs shooting operations and
records the seismic energy reflected from subsurface structures. A land seismic
data acquisition crew utilizing an explosives unit is supported by several drill
crews, generally furnished by third parties under short-term contracts. Drill
crews operate in advance of the seismic data acquisition crew and bore shallow
holes for small explosive charges that, when detonated, produce the necessary
seismic impulse. In locations where conditions dictate or where the use of
explosives is precluded due to regulatory, topographical or ecological factors,
a mechanical vibrating unit or compressed air unit is substituted for explosives
as the seismic energy source. The Company also employs specialized crew
mobilization equipment to improve productivity in certain applications,
including helicopters for rugged terrain or in agricultural areas, small
watercraft for transition zone applications, and man-portable equipment in
jungle and other environments where vehicular access is limited. Depending on
the size of the seismic survey, the location and other logistical factors, a
seismic data acquisition crew operated by the Company may involve from as few as
30 to as many as 1,500 employees.

     One of the challenges inherent in land seismic data acquisition is
operating in difficult logistical environments without disrupting the sensitive
ecosystems in which surveys are frequently located. The Company currently
operates approximately 10,000 channels of remote digital seismic equipment,
which can be deployed without the use of conventional seismic cables, thereby
allowing access to such environments. Remote digital seismic equipment, which
uses radio signals to transmit data, is typically used in transition zone and
other logistically challenging environments such as highly populated regions
with numerous topographic obstructions and areas where conventional cable-based
recording systems are impractical. The Company has over 20 years of experience
operating in transition zone environments in the Gulf Coast region of the United
States, the Far East and Africa.

     Once recorded by the seismic data acquisition crew, seismic data is
computer processed to enhance the recorded signal by reducing noise and
distortion and improving resolution to produce a representation of the survey
site's subsurface structures. The Company presently has two data processing
centers at which it performs seismic data processing services. These centers are
located in Houston and Dallas, Texas.

     The Company markets its seismic data acquisition and processing services
from its Houston and Calgary corporate offices and its regional and
international administrative centers by personnel whose duties include
technical, supervisory or executive responsibilities. The Company generally
acquires seismic data on an exclusive contract basis for oil and gas companies
on:

     - a turnkey basis, which provides a fixed fee for each project;

     - a term basis, which provides for a periodic fee during the term of the
       project; or,

     - a cost-plus basis, which provides that the costs of a project, plus a
       percentage fee, are borne by the customer.
                                        2
<PAGE>   5

     In addition, in the United States and Canada, the Company acquires and owns
certain multi-client seismic data that is marketed broadly on a non-exclusive
basis to oil and gas companies.

     The Company conducts a substantial portion of its business in currencies
other than the U.S. or Canadian dollars, particularly various Latin American
currencies, and its operations are subject to fluctuations in foreign currency
exchange rates. Accordingly, certain of the Company's international contracts
could be significantly affected by fluctuations in exchange rates, particularly
in Brazil and Colombia. The Company's international contracts requiring payment
in currency other than U.S. or Canadian dollars typically are indexed to
inflationary tables and generally are used for local expenses. The Company
attempts to structure the majority of its international contracts to be billed
and paid at a certain U.S. dollar conversion rate.

MARKET AREAS

     In 1999, the Company conducted seismic operations in the United States,
Canada, Latin America and the Far East and has conducted activities in the
Middle East and West Africa within the last three years.

     The following table sets forth the Company's revenues by geographic area,
on a pro forma basis for the year ended December 31,1997 and on an actual basis
for the years ended December 31, 1998 and 1999, for the periods shown:

(1) Solid State's fiscal year end was August 31 prior to the year ended December
    31, 1998 when it was changed to a calendar year. For pro forma purposes,
    revenues for Solid State have been adjusted to reflect the period December
    1, 1996 through August 31, 1997 to combine with GGI's nine months ended
    September 30, 1997 and the Company's three months ended December 31, 1997.
    The revenues for the three months ended December 31, 1997 include the
    combined operations of Solid State and Grant. See Notes 1 and 4 to the
    Consolidated Financial Statements of the Company and GGI for additional
    geographic information.

BACKLOG

     The Company's backlog for seismic data acquisition services represents the
revenues anticipated to be received by the Company in connection with
commitments for contracted services received from its customers. As of December
31, 1999, the Company estimates that its total backlog was approximately $24.2
million, all of which is expected to be completed in 2000. This compares to the
Company's estimated total backlog of $38.2 million and $144.4 million at
December 31, 1998 and 1997, respectively. The decrease reflects the overall
decline in demand, as described above, for seismic data acquisition and
processing services on a worldwide basis that began during the last half of
1998. As of March 24, 2000, the Company estimates that its total backlog is
approximately $30.8 million. Most of the Company's contracts are terminable by
the customer upon relatively short notice and, in some cases, without penalty.
The Company's backlog as of any particular date is not indicative of the likely
operating results for any succeeding period, and there can be no assurance that
any amount of backlog will ultimately be realized as revenue.

CAPITAL EXPENDITURES AND TECHNOLOGY

     The Company's ability to compete and maintain a significant market position
in the land and transition zone seismic data acquisition business is partially
driven by its ability to provide technology comparable to that of its primary
competitors. Accordingly, the Company continually maintains and periodically
upgrades its seismic data acquisition equipment to maintain its competitive
position. The Company spent approximately $36.3 million on capital expenditures
for the fifteen-month period ending December 31, 1998. This included
approximately $12.4 million in the fourth quarter of 1997 and approximately
$23.9 million during 1998. These expenditures were used principally to upgrade
and expand the Company's seismic data acquisition equipment. Due to the downturn
in the seismic industry, the Company incurred $9.5 million in 1999 on capital
expenditures and has budgeted $5.1 million in capital expenditures for 2000. The
level of future capital expenditures will depend on the availability of funding
and market requirements as dictated by industry activity levels.

     Over the past several years, the Company has focused its efforts on
developing operating procedures and acquiring equipment that will enhance the
efficiency of its seismic data acquisition crews and reduce the time required to
complete projects. The Company's strategy does not contemplate the development
of proprietary seismic data acquisition equipment, but instead relies on the use
of third-party equipment suppliers to provide such equipment, although certain
equipment will be customized to the Company's specifications to enhance
operating efficiency. Certain of the equipment, processes and techniques used by
the Company are subject to the patent rights of others, and the Company holds
non-exclusive licenses with respect to a number of such patents. While the
Company regards as beneficial its access to third-party technology through
licensing, the Company believes that substantially all presently licensed
technology could be replaced without significant disruption to its business.

LICENSING OF MULTI-CLIENT DATA

     The Company acquires and processes seismic data for its own account by
conducting surveys either partially or wholly funded by multiple customers. In
this mode of operation, ownership of the data is retained by the Company and the
data is licensed on a non-exclusive basis. As of December 31, 1999, there were
$1.7 million of commitments from customers for multi-client data acquisition
projects.

     Factors considered when determining whether to undertake a multi-client
survey include the availability of customer commitments to offset a percentage
of the project cost, the number of potential customers for the completed data,
the location to be surveyed; the probability and timing of future lease,
concession, exploration and development activity in the area; and, the
availability, quality and price of competing data. Although the Company
anticipates obtaining commitments for a substantial majority of the cost of any
future multi-client data survey and conducts market and cost analyses to
determine the market demand and necessary funding prior to undertaking a
project, it still may not be able to fully recoup its costs if it substantially
underestimates the cost or overestimates market demand for such multi-client
data survey.

CUSTOMERS AND PROJECTS

     The Company's customers consist of domestic and international oil and gas
companies and seismic data marketing companies. As is the case for many service
companies in the oil and gas industry, a relatively small number of customers or
a limited number of significant projects may account for a large percentage of
the Company's net revenues in any given year. Moreover, such customers and
projects may, and often do, vary from year to year. For 1999, the Company's five
largest customers accounted for approximately $21.3 million, or 32.3%, of
revenues and no single customer accounted for 10% or more of revenues. During
1998, the Company's five largest customers accounted for approximately 28.8% of
revenues, and no single customer accounted for 10% or more of revenues. In the
first nine months of 1997, GGI had revenues from a foreign national oil company
of approximately $14.0 million, or 15% of total revenues, and also from a U.S.
based exploration company of approximately $9.9 million, or 11% of total
revenues. During 1997, on a pro forma basis, the Company's five largest
customers accounted for approximately 31.9% of revenues. During 1997, on a pro
forma basis, no customer accounted for 10% or more of the Company's combined
revenues.

COMPETITION

     The acquisition and processing of proprietary and multi-client seismic data
for the oil and gas industry is highly competitive worldwide. However, as a
result of changing technology and increased capital requirements, the seismic
industry has consolidated substantially since the late 1980's, thereby reducing
the number of competitors. The Company's principal competitors in North America
are Baker Atlas, Inc., a subsidiary of Baker Hughes, Inc.; Veritas DGC, Inc.;
and Geco-Prakla Inc., a subsidiary of Schlumberger Limited. The Company competes
against these three companies for most of its seismic data acquisition and
processing contracts in North America. Although precise comparative figures are
not available, the Company believes that its principal competitors have
financial, operating and other resources in excess of its own. Also in North
America, the Company competes with approximately 20 smaller companies that
target narrow market segments. In Latin America and the Far East, the Company
competes with Baker Atlas, Compagnie General de Geophysique, Geco-Prakla and a
few smaller local competitors. Competition is based primarily on price, crew
availability, prior performance, technology, safety, quality, dependability and
the contractor's expertise in the particular area where the survey is to be
conducted.

EMPLOYEES

     As of March 24, 2000, the Company employed approximately 455 full-time and
630 temporary contract personnel worldwide. None of the Company's employees is
subject to collective bargaining agreements. The Company considers its relations
with its employees to be good.

ENVIRONMENTAL MATTERS/GOVERNMENTAL REGULATION

     The Company's domestic operations are subject to a variety of federal,
state and local laws and regulations relating to the protection of human health
and the environment, the violation of which may result in civil or criminal
penalties. The Company invests financial and managerial resources to comply with
such laws and regulations and management believes that it is in compliance in
all material respects with applicable environmental laws and regulations.
Although such environmental expenditures by the Company historically have not
been significant, there can be no assurance that these laws and regulations will
not change in the future or that the Company will not incur significant costs in
the future performance of its operations. The Company is not involved in any
legal proceedings concerning environmental matters and is not aware of any
claims or potential liability concerning environmental matters that could have a
material adverse impact on the Company's financial position, cash flows or
results of operations.

     The Company's operations outside of the United States are subject to
similar environmental regulation in a number of foreign locations, including
Canada, Latin America, and the Far East. Management believes that the Company is
in material compliance with the existing environmental requirements of these
foreign governmental bodies. The Company has not incurred any significant
environmental costs in connection with the performance of its foreign
operations; however, any regulatory changes that impose additional environmental
restrictions or requirements on the Company or its customers could adversely
affect the Company through increased operating costs and decreased demand for
the Company's services.

       Company regarding future demand for the Company's seismic services and
       other events and conditions that may influence demand for the Company's
       services and its performance in the future; and

     - statements concerning the Company's business strategy and expectations,
       industry conditions, market position, backlog, future operations,
       margins, profitability, liquidity and capital resources.

     Forward-looking statements can generally be identified by such terminology
as "may," "will," "expect," "believe," "anticipate," "project," "estimate" or
similar expressions. Such statements are based on certain assumptions and
analyses made by the Company's management in light of its experience and its
perception of historical trends, current conditions, expected future
developments and other factors that it believes to be appropriate. The Company
cautions that such statements are only predictions and not guarantees of future
performance and that actual results, developments and business decisions may
differ from those envisioned by the forward-looking statements.

     All phases of the Company's operations are subject to a number of
uncertainties, risks and other influences, many of which are beyond the control
of the Company. Any one of such influences, or a combination, could materially
affect the accuracy of the forward-looking statements and the projections on
which the statements are based. Some important factors that could cause actual
results to differ materially from the anticipated results or other expectations
expressed in the Company's forward-looking statements include the following:

  Dependence on the Oil and Gas Industry; Industry Volatility.

     The Company's business depends in large part on the conditions of the oil
and gas industry, and specifically on the capital expenditures of the Company's
customers. As a result of the decline in oil and gas prices beginning late in
the third quarter of 1998, the level of overall oil and gas industry activity
declined substantially from levels experienced in recent years. Decreases in the
Company's customers' capital spending in connection with industry downturns have
had and will likely result in decreased demand for the Company's services. The
Company's results of operations have varied and may continue to vary depending
on the demand for services. Unless demand increases, the Company will likely
continue to operate at a loss.

  The Company's Business could be adversely affected by Intense Price
  Competition in a Slack Market.

     Competition among seismic contractors historically is, and will continue to
be, intense. Competitive factors have in recent years included price, crew
experience, equipment availability, technological expertise and reputation for
quality and dependability. Certain of the Company's competitors operate more
data acquisition crews than the Company does and have substantially greater
financial and other resources. These larger and better-financed operators could
enjoy an advantage over the Company if the competitive environment for contract
awards shifts to one characterized principally by intense price competition.

  The Company's Multi-Client Data Library could become Impaired due to Weak
  Demand or Technological Obsolescence.

     The Company has invested significant amounts in acquiring and processing
multi-client data. Although the management of the Company expects to recover all
the costs of such surveys, there is no assurance that the Company will be able
to do so in the future. Technological, regulatory or other industry or general
economic developments could render all or portions of the Company's library of
multi-client data obsolete or otherwise impair its value. As of December 31,
1999 and 1998, the total value of the capitalized multi-client data library was
$27.4 million and $10.9 million, respectively.

  Risks of High Levels of Fixed Costs.

     The Company's business has high fixed costs, and downtime or low
productivity due to reduced demand, weather interruptions, equipment failures or
other causes could result in significant operating losses.

  Technology Risks.

     Seismic data acquisition and processing is a capital-intensive business.
The development of seismic data acquisition and processing equipment has been
characterized by rapid technological advancements in recent years and the
Company expects this trend to continue. Manufacturers of seismic equipment may
develop new systems that have competitive advantages over systems now in use
that could render the Company's current equipment obsolete or require the
Company to make significant unplanned capital expenditures to maintain its
                                        6

competitive position. Under such circumstances, there can be no assurance that
the Company would be able to obtain necessary financing on favorable terms.

  Dependence upon Significant Customers.

     The Company derives a significant amount of its revenue from a small number
of major and independent oil and gas companies. The inability of the Company to
continue to perform services for a number of its large existing customers, if
not offset by contracts with new or other existing customers, could have a
material adverse effect on the Company's business and operations.

  Intense Competition

     The Company competes in a highly competitive area of the oil field services
industry. The Company's services are sold in a highly competitive market and its
revenues and earnings may be affected by the following factors:

     - changes in competitive prices;

     - fluctuations in the level of activity and major markets;

     - general economic conditions; and

     - governmental regulation.

     The Company competes with the oil and gas industry's largest seismic
service providers. Management of the Company believes that the principal
competitive factors in the market areas served by the Company are product and
service quality and availability, technical proficiency and price.

  Risks of International Operations.

     The Company's international operations, which are expected to continue to
contribute materially to revenues for the foreseeable future, are subject to
risks inherent in doing business in foreign counties. These risks include, but
are not limited to:

     - political changes;

     - expropriation;

     - currency restrictions and changes in currency exchange rates;

     - taxes; and

     - boycotts and other civil disturbances.

     The risks associated with operating internationally are reflected in the
$60.1 million decrease in the Company's international revenues, excluding
Canada, in 1999 as compared with 1998. The decrease was primarily attributable
to general economic conditions and political events in South America, the
economic downturn in the Far East and the overall world market for oil and gas.

     Although it is impossible to predict the likelihood of such occurrences or
their effect on the operations of the Company, the management of the Company
believes that these risks are acceptable. However, the occurrence of any one of
these events could have a material adverse effect on the Company's operations.

  Dependence on Key Personnel.

     The Company depends on the continued services of its executive officers and
other key management personnel. If the Company were to lose any of these
officers or other management personnel, this could adversely affect its
operations.

ITEM 2. PROPERTIES.

     The Company owns a 30,000 square foot building and storage yard in Houston,
Texas, which serves as its corporate headquarters, and leases a 60,000 square
foot building, also in Houston, Texas, which serves as a warehouse and staging
facility. The Company also owns an office, staging and repair facility located
on a two-acre tract in New Iberia, Louisiana. In Calgary, Alberta (Canada), the
Company owns an 18,000 square foot building and storage yard that serves as the
Company's Canadian headquarters. In addition, the Company leases office,
warehouse and storage space in areas throughout the world as may be required
from time to time to support the Company's operations.

ITEM 3. LEGAL PROCEEDINGS.

     The Company is involved in or threatened with other various legal
proceedings from time to time arising in the ordinary course of business.
Management of the Company does not believe that any liabilities resulting from
any such current proceedings will have a material adverse effect on the
Company's financial position, cash flows, or results of operations.

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

     On October 25, 1999, holders of greater than a majority of the outstanding
common stock voting power of the Company acted, by written consent, to further
amend the Amended and Restated Certificate of Incorporation of the Company to
decrease the number of authorized aggregate shares of capital stock of the
Company from 60,000,000 to 55,000,000 shares thus decreasing the number of
authorized shares of the Company's preferred stock from 10,000,000 to 5,000,000
shares.

                                    PART II

ITEM 5. MARKET FOR COMPANY'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

     As of March 24, 2000, there were 14,547,055 shares of the Company's common
stock, $.001 par value per share (the "Common Stock"), outstanding. See Item 12
for the number of shares of Common Stock owned by the Company's executive
officers, directors and each person known to the Company to own beneficially
more than 5% of the outstanding shares of Common Stock. The Common Stock is not
listed on any stock exchange or qualified for trading on any other market. The
Company does not anticipate paying cash dividends with respect to the common
stock in the future. In addition, the payment of cash dividends is currently
prohibited by the indenture governing the Company's 9  3/4% Senior Notes Due
2008 and credit agreements governing the Company's other indebtedness for
borrowed money.

ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
       OF OPERATIONS.

OVERVIEW

     The Company was formed in September 1997. On September 30, 1997, the
Company acquired substantially all of the assets and assumed certain liabilities
of GGI under GGI's Second Amended Plan of Reorganization (the "Plan"), which was
confirmed by The United States Bankruptcy Court for the District of Delaware on
September 15, 1997. On December 23, 1997, the Company, through a wholly owned
Canadian subsidiary, acquired all of the outstanding shares of Solid State.

     The Company's business activities involve the performance of land and
transition zone seismic data acquisition services in selected markets worldwide,
including the United States, Canada, Latin America and the Far East. The Company
generally acquires seismic data on an exclusive contract basis for oil and gas
companies on:

     - a turnkey basis, which provides a fixed fee for each project;

     - a term basis, which provides for a periodic fee during the term of the
       project; or,

     - a cost-plus basis, which provides that the costs of a project, plus a
       percentage fee, are borne by the customer.

     In addition, in the United States and Canada, the Company acquires and owns
certain multi-client seismic data that is marketed broadly on a non-exclusive
basis to oil and gas companies.

     In December 1996, GGI filed for protection under the United States
Bankruptcy Code and began its reorganization under the supervision of the
Bankruptcy Court. In connection with its reorganization, GGI replaced its senior
management, disposed of unprofitable operations, operated as
debtor-in-possession and developed the Plan, which was confirmed by the
Bankruptcy Court on September 15, 1997 and consummated on September 30, 1997
(the "Effective Date"), with the Company's purchase of substantially all of the
assets and assumption of certain liabilities of GGI.

     As a result of the decline in oil and gas prices beginning late in the
third quarter of 1998, the level of overall oil and gas industry activity, both
domestically and in certain international regions, has declined substantially
from levels experienced in recent years. Decreases in exploration and production
companies' capital spending in connection with industry downturns have had and
will likely result in decreased demand for the Company's services. The Company's
global seismic crew count has decreased from average of eighteen to twenty
during 1998 to a total of nine active crews as of March 24, 2000.

     The historical results of operations of the Company for the years ended
December 31, 1998 and 1999 are presented below. Such results are not directly
comparable to the results of operations of GGI or the combined results of GGI
and the Company for the twelve months ended December 31, 1997 due to the effects
of the purchase of Solid State in September 1997.

</TABLE>

THE COMPANY FOR THE TWELVE-MONTH PERIOD ENDED DECEMBER 31, 1999 COMPARED WITH
THE TWELVE-MONTH PERIOD ENDED DECEMBER 31, 1998

     Revenues. Revenues for 1999 were $66.0 million, compared with $175.5
million for 1998. The decrease of $109.5 million, or 62.4%, was the result of
lower demand for the Company's seismic acquisition services in both the domestic
and international markets. The decrease in the price of oil and gas that
occurred between the fourth quarter of 1998 and the first quarter of 1999
significantly reduced demand for the Company's services. Although commodity
prices have returned and are in fact at historically high levels, demand for
land and transition zone seismic acquisition services remains severely depressed
over levels experienced in recent years. The Company is unable to predict with
any certainty when the market for seismic services is likely to recover and,
until such time, will continue to experience significant operating losses.

     Revenues from United States data acquisition operations decreased $49.4
million, or 63.5%, from $77.7 million in 1998 to $28.3 million in 1999. This
decrease was attributable to the Company operating six to eight contract seismic
data acquisition crews from time to time in the United States during 1998,
compared with only two to four crews in 1999. In addition, during 1999, two of
the crews were performing multi-client projects with average underwriting, or
pre-commitments, of approximately 39% of total project costs. This compares to
the same period in 1998 when the average underwriting for multi-client projects
was approximately 79% of total costs. The significance of the decrease in
underwriting affected 1999 sales because,

                                       11
<PAGE>   14

pursuant to the Company's revenue recognition policy, a portion of project
underwriting is recognized as revenue during the current period. Firm backlog
for United States data acquisition projects at December 31, 1999 was $8.1
million.

     Revenues from seismic data processing operations, purchased in July 1998,
were $1.5 million for 1999 compared to $957,000 for 1998. The Company operated
seismic data processing centers during 1999 in Midland, Dallas and Houston,
Texas. These centers process both third-party and Company-owned multi-client
data. In January 2000, the Company completed the consolidation of its Midland
center with operations in the Houston seismic data processing center.

     Revenues from the Canadian data acquisition operations decreased $4.0
million, or 28.2%, from $14.2 million in 1998 to $10.2 million in 1999. This
decrease was due to a decline in activity experienced during the first three
quarters of 1999 when compared to first three quarters of 1998. This was
partially offset by increased seismic activity during the fourth quarter of 1999
when compared to fourth quarter 1998. The Company is encouraged by the recovery
of the Canadian market experienced at the end of 1999. During the first quarter
of 2000, four to five land seismic crews were operating in Canada as compared to
only three during the first quarter of 1999.

     The Company began its multi-client data acquisition activities in the
United States and Canada during 1998. Multi-client crew operations began in the
second quarter of 1998 and were continuous through December 1999. During that
time, 17 projects were completed in Texas, California, Wyoming and Canada
covering a total of 1,648 square miles. There were 621 square miles completed in
1998. The cost of these projects was $23.7 million with approximately $18.6
million, or 78.4%, underwritten by third parties. There were 1,027 square miles
completed in 1999. The cost of these projects was $41.3 million with
approximately $18.4 million, or 44.5%, underwritten by third parties. Due to the
continued depressed demand for seismic services, an inability to secure adequate
initial customer underwriting and a lack of sufficient liquidity, the Company
has curtailed its strategy of building a multi-client data library in the
southern United States. As long as these factors persist, the Company will be
very selective in its decision to participate in multi-client projects. For the
year 2000, the Company has committed to only two multi-client projects, both
located in Canada. Estimated project costs are $1.3 million with 100% of the
costs underwritten by third parties. Revenues associated with the underwritten
portion of multi-client data programs are recognized as a component of the data
acquisition revenues discussed above. Revenue from sales of the data library for
1999 was $3.5 million, compared to only $388,000 for 1998.

     Revenues in Latin America decreased $37.5 million, or 71.4%, from $52.6
million in 1998 to $15.1 million in 1999. During 1998, the Company's Latin
American operations consisted of as many as eight seismic crews operating in
Bolivia, Brazil, Colombia, Ecuador and Guatemala. During 1999, four to five
crews operated in Mexico, Ecuador, Guatemala, Brazil and Colombia. There are
currently a total of three land seismic acquisition crews operating or
mobilizing in this region.

     Revenues from the Far East decreased $22.6 million, or 75.0%, from $30.1
million in 1998 to $7.5 million in 1999. During 1998, the Company operated as
many as five crews in the region: one land and two transition zone crews in
Bangladesh, and one land and one transition zone crew in Indonesia. During 1999,
the Company operated one to two crews, primarily in Indonesia. The Indonesian
crew is currently the only crew operational in this region.

     Expenses. Direct operating expenses as a percentage of revenues increased
to 82.5% in 1999 from 72.6% in 1998. This percentage increase can be attributed
to reduced operating margins on multi-client projects during the third and
fourth quarters of 1999 and unanticipated start-up and operating expenses on two
Latin American crews incurred during the second and third quarters of 1999.
Direct operating expenses for the twelve months ended December 31, 1999
decreased $72.9 million, or 57.2%, to $54.5 million, compared to $127.4 million
for the twelve months ended December 31, 1998. This decrease is a result of the
revenue decreases experienced throughout all the Company's operating regions as
described above.

     Selling, general and administrative expenses decreased $.7 million, or
4.9%, to $13.5 million in 1999 from $14.2 million in 1998. This reduction is the
result of the Company's effort throughout 1999 to reduce support

                                       12
<PAGE>   15

and overhead personnel in all of its operating regions and at the corporate
office level. There have been limited increases in support and overhead
personnel, during the third and fourth quarters of 1999, in response to the
increase in demand for seismic services being experienced primarily in the
Company's international markets. Selling, general and administrative expenses
increased as a percentage of revenue to 20.5% in 1999 from 8.1% in 1998. This
increase is a result of the revenue decreases experienced throughout all the
Company's operating regions as described above.

     Depreciation and amortization increased $2.3 million, or 9.7%, to $26.1
million in 1999 from $23.8 million for 1998. This increase reflects additional
amortization of the Company's multi-client projects, partially offset by a
reduction in capital expenditures during 1999 as compared to 1998. Capital
expenditures were $9.5 million and $23.9 million for 1999 and 1998,
respectively.

     The Company recorded charges for asset impairment of $5.0 million and $3.8
million for 1999 and 1998, respectively. All of the 1999 charge and $3.2 million
of the 1998 impairment were special charges to reduce the carrying value of the
Company's multi-client data library to net realizable value, based on revised
future licensing prospects for such data due to the current downturn in the
industry and the Company's recent sales experience for such data. On a quarterly
basis, management estimates the residual value of each survey, and additional
amortization is provided if the remaining revenues reasonably expected to be
obtained from any survey are less than the carrying value of such survey. Also
included in the 1998 charge was a $564,000 write-down in the carrying value of
certain non-operating depreciable fixed assets to salvage value.

     Other Income (Expenses). Interest expense, net, increased $2.7 million to
$12.0 million in 1999 from $9.3 million in 1998. A portion of the increase can
be attributed to the Company's sale on February 18, 1998 of $100 million of 9
 3/4% Senior Notes (the "Senior Notes") due 2008. Consequently, 1999 included an
additional month and a half of interest expense on the Senior Notes as well as
interest on increased borrowings under the Company's revolving credit facility.
These funds were used to finance multi-client data projects, to fund capital
expenditures and provide working capital for operations.

     Tax Provision. The income tax provision consisted of income taxes in
foreign countries. For 1998 this includes provisions for taxes in Colombia,
Ecuador, Guatemala, Bangladesh and Indonesia; for 1999 this includes provisions
for taxes in Colombia, Ecuador, Bangladesh and Canada. No benefit for United
States federal income tax loss carryforwards was recorded in either period,
given the uncertainty of realization of such tax benefits.

THE COMPANY FOR THE TWELVE-MONTH PERIOD ENDED DECEMBER 31, 1998 COMPARED WITH
THE COMPANY AND GGI COMBINED TWELVE-MONTH PERIOD ENDED DECEMBER 31, 1997

     The following analysis compares the operating results of the Company for
the twelve-month period ended December 31, 1998 with combined operating results
of the Company for the three-month period ended December 31, 1997 (including the
operating results of Solid State for such period) and the operating results of
GGI for the nine-month period ended September 30, 1997. As described above,
Grant began operations immediately following its acquisition of substantially
all of the assets and certain liabilities of GGI on September 30, 1997 and Grant
acquired Solid State in December 1997. Because of the significant changes in
Grant's control and management and scope of operations following the
consummation of the Plan, comparisons may not be meaningful.

     Revenues. Revenues of the Company for the twelve months ended December 31,
1998 were $175.5 million, compared with $130.6 million of combined revenue for
GGI and the Company for the twelve months ended December 31, 1997. The increase
of $44.9 million, or 34.4%, was the result of growth in revenues in both the
United States and the Far East and the inclusion of a full year of Solid State's
results of operations in 1998 compared to only three months in 1997.

     Revenues from the United States operations increased $25.0 million, or
46.4%, from $53.7 million to $78.7 million in 1998. Revenues from the United
States data acquisition operations increased $24.1 million, or 44.7%, from $53.7
million in 1997 to $77.8 million in 1998. This increase was due primarily to the
addition of two Solid State crews in the northern United States for the entire
year versus only one crew for three months

                                       13
<PAGE>   16

in 1997 and the addition of new and more efficient recording instrumentation.
Productivity was enhanced by increasing the seismic recording channel count per
crew and, whenever possible, utilizing a twenty-four hour recording schedule.
During 1998, there were as many as eight seismic crews operational in the United
States versus only six to seven crews operational in 1997. Beginning late in the
third quarter of 1998, due primarily to the low oil and gas prices, demand for
data acquisition recording services in the United States and elsewhere began to
decline. By the end of December 1998, there were six crews operating or
mobilizing in the U.S.

     Revenues from seismic data processing were $957,000 for 1998. The Company
purchased its seismic data processing operations in July 1998; therefore, there
are no comparable results for 1997. The Company operated processing centers in
Midland and Dallas, Texas for the remaining six months and began operations in a
newly established Houston, Texas center during the fourth quarter of 1998.

     Revenues from the Canadian data acquisition operations increased $9.7
million, or 215.6%, from $4.5 million in 1997 to $14.2 million in 1998. The
Company acquired these operations from Solid State effective September 30, 1997.
The increase in 1998 is the result, therefore, of including a full year of
operations in 1998 versus only three months in 1997. From time to time during
1998, the Company operated as many as six land seismic crews throughout Canada.

     The Company began its multi-client data acquisition activities in the
United States and Canada during 1998. Crew operations began in the second
quarter with significant activity occurring in both the third and fourth
quarters. The Company has completed or is conducting eleven data library
projects totaling approximately 1,234 square miles in Texas, California, Wyoming
and Canada. At December 31, 1998, 621 square miles had been completed and an
additional 246 square miles were scheduled for completion by March 31, 1999. The
Company and GGI had no multi-client data activity in 1997. Revenues associated
with the underwriters' portion of multi-client data programs are recognized as
part of the data acquisition revenues discussed above in the southern United
States, northern United States and Canada.

     Revenues in Latin America decreased $6.0 million, or 10.2%, from $58.6
million in 1997 to $52.6 million in 1998. During 1998, the Company operated as
many as eight land seismic crews in Brazil, Guatemala, Colombia, Ecuador and
Bolivia. During 1997, combined Latin American operations for GGI and the
Company, while operating in the same countries, consisted of as many as ten land
seismic data acquisition crews. The Brazilian operations were completed in March
1998 and the equipment was moved to work in Guatemala. The Colombian operations
were completed in the third quarter of 1998 and both the Guatemalan and Bolivian
contracts were finished in the fourth quarter of 1998. Ecuadorian operations
were completed in February 1999.

     Revenues from the Far East increased $16.6 million, or 123.1%, from $13.5
million in 1997 to $30.1 million in 1998. During 1998, the Company operated as
many as five crews in the region: one land and two transition zone crews in
Bangladesh and one land and one transition zone crew in Indonesia. During 1997,
in Bangladesh, GGI and the Company operated one crew for the entire year and
mobilized one additional transition zone crew that began operations in July
1997. By December 1998, there were three active crews in the region.

     Expenses. Direct operating expenses for the twelve months ended December
31, 1998 increased $28.0 million, or 28.2%, to $127.4 million compared with
$99.4 million for the twelve months ended December 31, 1997. Direct operating
expenses as a percentage of revenues decreased to 73.5% in 1998 from 76.2% in
1997. The overall dollar increase was the result of increased crew activity in
the southern United States and the Far East and the inclusion of a full year of
Solid State's results in 1998 versus only three months in 1997. The percentage
decrease is the result of improvements in operating efficiencies primarily in
the United States. These improvements were the results of upgrading and
expanding the Company's seismic data recording equipment, careful and detailed
project cost analysis and management's ability to properly assess operating
risk.

     Selling, general and administrative expenses for the twelve months ended
December 31, 1998 increased $4.2 million to $14.2 million from $10.0 million in
1997. Selling, general and administrative expenses as a percentage of revenue
increased only marginally to 8.1% in 1998 from 7.6% in 1997. The overall dollar

                                       14
<PAGE>   17

increase was primarily due to an approximate $1.5 million increase as a result
of the inclusion of Solid State for a full year in 1998 versus only three months
in 1997, $1.1 million of additional costs incurred to develop international and
domestic markets, $537,000 for corporate provisions for doubtful accounts and
incentive bonuses and the remainder related to a general increase in corporate
support services.

     Depreciation and amortization increased $10.8 million to $23.8 million in
1998 from $13.0 million for 1997. The increase was due to an increase of
approximately $3.8 million due to the inclusion of Solid State for a full year
in 1998 versus only three months in 1997, $1.5 million for the amortization of
goodwill, $3.8 million of depreciation on newly purchased assets and $1.5
million for amortization of the multi-client data library.

     The charge for asset impairment was $3.8 million for 1998 compared to $6.4
million in 1997. At December 31, 1998, the Company recorded a special charge of
$3.2 million to reduce the carrying value of its multi-client data, acquired
through the purchase of Solid State during the fourth quarter of 1997, to its
net realizable value based on revised estimates of future licensing prospects
for such data. The charge for asset impairment recorded in 1997 included a
special charge of $5.9 million to write down the acquired Solid State
multi-client data to its then-estimated net realizable value. The acquisition of
Solid State in 1997 occurred in two parts: the acquisition of the majority
interest and the acquisition of the minority interest. The 1997 impairment
charge relates only to certain assets of Solid State that were acquired during
the acquisition of the majority interest. These assets had been originally
recorded at historical cost. None of the $6.4 million impairment charge
recognized in 1997 related to the assets acquired as part of the acquisition of
the minority interest. Also included in 1998, was a charge of $564,000 relating
to the write-down in the carrying value of certain non-operating depreciable
fixed assets to salvage value. The remaining 1997 charge relates to a $247,000
write-down in the carrying value of certain non-operating depreciable fixed
assets to salvage value and a $253,000 write-down in the carrying value of
certain other investments and joint ventures.

     Other Income (Expenses). Interest expense, net, increased $4.2 million to
$9.3 million in 1998 from $5.1 million in 1997. This increase was the result of
interest on debt both incurred and assumed by the Company as a result of the
Solid State acquisition and from the sale on February 18, 1998 of $100 million
of 9  3/4% senior notes due 2008 (the "Senior Notes"). Proceeds from the sale
were used to retire substantially all of the Company's outstanding indebtedness,
to fund capital expenditures and to provide working capital for general
corporate purposes.

     Reorganization costs of $3.5 million in 1997 related to charges incurred in
connection with GGI's reorganization, which began in December 1996 and was
completed in September 1997. No comparable reorganization charges were incurred
by the Company in the three months ended December 1997 or for the year ended
December 31, 1998.

     Other income of $1.0 million for 1997 was the result of settlement of a
long-standing dispute between one of GGI's Brazilian subsidiaries and a former
customer relating to services rendered on contracts dating back to 1983. In
settlement of all claims, GGI received payment, net of related costs and
expenses, of approximately $2.4 million in July 1997. Income from that
settlement was offset by approximately $767,000 in costs associated with the
Solid State acquisition and approximately $289,000 of foreign currency exchange
losses, primarily related to US dollar based loans owed by Solid State prior to
its acquisition by Grant. In 1998, the Company recorded $635,000 in litigation
expense associated with the settlement of litigation related to the Solid State
acquisition, representing the cash paid by Elliott Associates, L.P. ("Elliott")
and the $0.25 discount permitted the plaintiffs to purchase the Company's common
stock in the subscription offering (see Note 13 to the Consolidated Financial
Statements).

     Tax Provision. The income tax provision in both periods consisted of income
taxes in foreign countries. The increase in 1998 compared with 1997 is a result
of higher taxable income in Indonesia and Guatemala. No provision for United
States federal income tax was made in 1997 as GGI and the Company each had
taxable losses for which no benefit was recorded under FAS 109. In 1998, the
Company provided for approximately $100,000 of alternative minimum tax in the
United States.

LIQUIDITY AND CAPITAL RESOURCES

     As discussed previously, demand for the Company's seismic acquisition
services has been and continues to be adversely affected by reduced industry
activity continuing through December 31, 1999. As a result, the Company has
required additional financing to continue operations, complete its capital
expenditure program, implement its business strategy and meet its principal and
interest obligations with respect to the Senior Notes and other indebtedness.
The Company's operating activities used $1.2 million in cash during 1999,
compared to cash generated of $17.3 million for the comparable period in 1998.
In 1999, cash used in operating activities was primarily due to the Company's
net loss of $45.8 million, partially offset by non-cash charges (impairment and
depreciation and amortization expense) and a decrease in accounts receivable.

     Between August 16, 1999 and December 29, 1999, the Company issued a total
of 149,000 shares of 8% exchangeable preferred stock (the "Exchangeable
Preferred Stock") to Elliott at a price of $100 per share. This equity financing
was required to supplement available cash, cash flow generated from operations
and borrowings under the credit facility with Foothill Capital Corporation
("Foothill") to provide sufficient liquidity to fund the Company's cash
requirements. Additionally, the Company issued 677 shares, 2,252 shares and
1,265 shares of Exchangeable Preferred Stock to Elliott as of October 1, 1999,
January 1, 2000 and February 7, 2000, respectively, as payment-in-kind dividends
on the Exchangeable Preferred Stock payable on those dates. On February 7, 2000,
the Company exchanged all the outstanding Exchangeable Preferred Stock, 153,194
shares, for an equal number of shares of its new 8% convertible preferred stock
(the "Convertible Preferred Stock") with a liquidation preference of $100 per
share. This was a non-cash transaction for the Company.

     In order to improve its liquidity and supplement its operating activities,
pursuant to a registration statement originally filed on October 28, 1999 and
declared effective on January 12, 2000, the Company offered to exchange (the
"Exchange Offer") $100,000,000 aggregate principal amount of its outstanding
Senior Notes for shares of its Convertible Preferred Stock with an aggregate
liquidation value equal to 65% of the aggregate principal amount of the Senior
Notes tendered, plus 100% of the accrued and unpaid interest thereon through the
date of the exchange. On January 19, 2000, a total of $56,320,000 of the Senior
Notes, together with $2,364,000 of accrued and unpaid interest, were exchanged
for 389,722 shares of Convertible Preferred Stock. The Senior Notes exchanged
represent all of the Senior Notes previously held by Elliott and Westgate
International, L.P. ("Westgate") No other Senior Notes were tendered and the
Exchange Offer expired on February 7, 2000. The consummation of the Exchange
Offer has increased the Company's liquidity by reducing its principal payment
obligations with respect to the Senior Notes and reducing the negative cash flow
impact of its interest payment obligations on the Senior Notes. The Company
intends to pay dividends on the Convertible Preferred Stock in additional shares
of Convertible Preferred Stock until further notice.

     In connection with the Exchange Offer, the Company solicited consents from
the holders of its Senior Notes in order to amend definitions and to modify
certain restrictive covenants in the indenture governing the Senior Notes. The
original indenture limited the Company's ability to incur additional
indebtedness, pay dividends or make certain other distributions, create liens,
sell assets or enter into certain mergers or acquisitions. The consent of
holders of a majority of the outstanding principal amount of the Senior Notes
held by holders other than the Company, its subsidiaries and affiliates was
required to approve the proposed amendments to the indenture. This required
majority was achieved by January 19, 2000. Following the tender of the Senior
Notes by Elliott and Westgate, the Company executed a First Supplemental
Indenture with LaSalle Bank National Association, the trustee under the
indenture governing the Senior Notes, dated January 19, 2000 that caused the
approved amendments to take effect. The First Supplemental Indenture, among
other things, amended the definition of permitted indebtedness to allow for the
increase of incurred debt from $25 million to $50 million and increased
additional indebtedness from $7.5 million to $10 million.

     The Company entered into a Loan and Security Agreement with Foothill and
Elliott dated May 11, 1999. Under the terms of the original credit facility, the
Company could borrow up to $25 million. The facility was comprised of a $6
million revolving credit facility and term loans of up to $11.5 million and $7.5
million. The credit facility has a three-year term and provides for borrowings
at an interest rate per annum of the prime rate plus 1 1/2%, secured by liens on

modifications to the credit facility were completed. The Foothill/Elliott credit
facility was increased from $25 million to $29 million. This was accomplished by
increasing commitments under the revolving credit facility from $6 million to
$10 million, subject to borrowing base limitations. In addition, the notional
$11.5 million term loan, which had been reduced through periodic principal
payments to $10.1 million, was increased to the original outstanding balance of
$11.5 million. The Company was in compliance with debt covenants included in the
Loan and Security Agreement as of December 31, 1999.

     As of December 31, 1999, the Company's total indebtedness was approximately
$127.9 million. The total indebtedness was comprised of $99.4 million aggregate
principal amount of the Senior Notes, $23.1 million outstanding on the
Foothill/Elliott credit facility and $5.4 million of combined loans and
capitalized leases primarily incurred for the purpose of financing capital
expenditures. Subsequent to the Exchange Offer, on March 30, 2000, the Company's
total indebtedness has been reduced to approximately $73.3 million, comprised of
$43.4 million in Senior Notes, $25.4 million outstanding on the Foothill/Elliott
credit facility and $4.5 million of combined loans and capitalized leases.

     The Company's ability to meet its debt service and other obligations will
depend on its future performance, which in turn is subject to economic
conditions (both general and within the oil and gas industry) and other factors
beyond the Company's control. If the Company is unable to generate sufficient
cash flow from operations or otherwise comply with the terms of the indenture,
the First Supplemental Indenture, the Foothill/Elliott credit facility or its
other debt instruments, it may be required to refinance all or a portion of its
existing debt or obtain additional financing/equity capital. There can be no
assurance that such refinancing or additional financing/equity capital will be
available on terms acceptable to the Company.

     The Company's internal sources of liquidity are its working capital and
cash flow from operations. External sources include borrowings, to the extent
available, under the Company's credit facility with Foothill/Elliott, equipment
financing and trade credit. In addition, the Company periodically enters into
equipment financing agreements with sellers of seismic data acquisition
equipment to pay all or a portion of the purchase price of such equipment and
regularly utilizes normal trade credit in connection with certain of its
purchases of goods and services to support its ongoing field crew activities.

     The Company's principal uses of liquidity will be to provide working
capital, finance capital expenditures, make principal and interest payments
required by the terms of its indebtedness and fund expenses associated with the
implementation of its business strategy, including the selective acquisition and
processing of multi-client data. Because of the traditionally longer period
required to collect receivables and the high costs associated with equipping and
operating crews outside of the United States and Canada, the Company requires
significant levels of working capital to fund its international operations,
excluding Canada. These operations, excluding Canada, accounted for 34.2% of
total revenues for the twelve months ended December 31, 1999.

     Capital expenditures for 1999 were approximately $9.5 million and were used
primarily to upgrade and expand the Company's seismic data acquisition and
recording equipment. The projected capital budget for the year 2000 is
approximately $5.1 million, primarily for the upgrade and replacement of the
Company's seismic data acquisition and recording equipment. Actual capital
expenditures may be reduced to a level consistent with funding availability.

     In addition to the capital expenditures listed above, for the year ended
December 31, 1999 the Company spent approximately $24.7 million on eleven
multi-client data acquisition projects principally located in Texas, California,
Wyoming and Canada. Customer commitments for those projects were approximately
40% of the project costs.

     Management believes that the completion of the Exchange Offer, together
with existing cash balances, available borrowing capacity and expected cash flow
from operations will allow the Company to meet capital and debt service
requirements for the next twelve months, based on expected operating levels. The
Company may require additional funds to support working capital requirements
associated with expanding its operations through internal growth or acquisitions
or for other purposes and may seek to raise additional funds through equity or
debt financing. There can be no assurance that additional financing will be
available on commercially reasonable terms, or that such financing will be
available at all.

FOREIGN CURRENCY RISK

     The Company conducts a substantial portion of its business in currencies
other than the U.S. or Canadian dollars, particularly various Latin American
currencies, and its international operations are subject to fluctuations in
foreign currency exchange rates. Accordingly, the Company's international
contracts could be significantly affected by fluctuations in exchange rates.
International contracts requiring payment in currency other than U.S. or
Canadian dollar typically are indexed to inflationary tables and generally are
used for local expenses. The Company attempts to structure the majority of its
international contracts to be billed and paid at a favorable U.S. dollar
conversion rate.

     The Company's operating results were positively impacted by foreign
exchange gains of approximately $351,000 for the year ended December 31, 1999,
negatively impacted by a foreign exchange loss of approximately $485,000 for the
year ended December 31, 1998, and positively impacted by $77,000 of foreign
exchange gains for the three months ended December 31, 1997.

EFFECT OF INFLATION

     Current economic conditions indicate that the costs of exploration and
production for oil and gas are increasing. The oil and gas industry historically
has experienced periods of rapid cost increases within short periods of time as
demand for drilling rigs, drilling pipe and other materials and supplies
increases. Increases in exploration and production costs could lead to a
decrease in such activities by oil and gas companies, which would have an
adverse effect on the demand for the Company's services.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting for
Derivative Instruments and Hedging Activities." SFAS No. 133 establishes
accounting and reporting standards requiring that every derivative financial
instrument be recorded in the balance sheet as either an asset or a liability
measured at its fair value, with changes in fair value recognized currently in
earnings. On July 7, 1999, the FASB delayed the effective date of SFAS No. 133
for one year. The delay, published as SFAS No. 137, applies to quarterly and
annual financial statements. SFAS No. 133, as revised by SFAS No. 137, is
effective for all fiscal quarters of all fiscal years beginning after June 15,
2000. The Company has not yet determined the impact of adoption.

YEAR 2000 READINESS DISCLOSURE

     The Year 2000 ("Y2K") problem refers to the inability of certain computer
systems and other equipment with embedded chips or processors (collectively
"Business Systems") to correctly interpret the century from a date in which the
year is represented by only two digits. Business Systems which are not Y2K ready
may not be able to correctly process certain data, or in extreme situations, may
cause a system to be disabled or fail to function reliably. As of March 24,
2000, the Company has not experienced any Y2K disruptions or failures in its
Business Systems and is not aware of any disruptions or failures with its
significant customers, suppliers, and business partners. Total costs incurred
through December 31, 1999 by the Company in connection with the Y2K issue,
including costs incurred in connection with a major upgrade of its accounting
and financial reporting systems to meet Y2K requirements, were approximately
$1.6 million.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company's debt consists of both fixed-interest and variable-interest
rate debt; consequently, the Company's earnings and cash flows, as well as the
fair values of its fixed-rate debt instruments, are subject to interest-rate
risk. The Company has performed sensitivity analyses to assess the impact of
this risk based on a hypothetical ten-percent increase in market interest rates.
Market rate volatility is dependent on many factors that are impossible to
forecast, and actual interest rate increases could be more severe than the
hypothetical ten-percent increase.

                                       18
<PAGE>   21

     The Company estimates that if prevailing market interest rates had been ten
percent higher throughout 1998 and 1999, and all other factors affecting the
company's debt remained the same, pretax earnings would have been lower by $1.0
million in 1998 and $1.3 million in 1999. With respect to the fair value of the
Company's fixed-interest rate debt, if prevailing market interest rates had been
ten percent higher at year-end 1998 and 1999, and all other factors affecting
the Company's debt remained the same, the fair value of the Company's fixed-rate
debt, as determined on a present-value basis, would have been lower by
approximately $1 million at December 31, 1998 and 1999, respectively. Given the
composition of the Company's debt structure, the Company does not, for the most
part, actively manage its interest rate risk.

EMPLOYMENT AGREEMENTS

     On January 27, 1999, the Company entered into a Separation Agreement and
Release (the "Separation Agreement") with Larry E. Lenig, Jr. in connection with
his resignation as the Company's President and Chief Executive Officer. Under
the terms of the Separation Agreement, Mr. Lenig will receive $15,000 per month,
plus health benefits, from March 1999 through December 2001, and $7,500 per
month, plus health benefits, from January 2002 through December 2003. Mr. Lenig
also received a bonus of $180,000, which was earned pursuant to his employment
agreement with the Company based upon the Company's 1998 results, and was
allowed to retain one-third (80,000) of the stock options awarded to him under
the 1997 Equity and Performance Incentive Plan. The stock options retained by
Mr. Lenig are exercisable until February 28, 2002. Mr. Lenig agreed that, for a

1997 EQUITY AND PERFORMANCE INCENTIVE PLAN

     The 1997 Equity and Performance Incentive Plan (the "Incentive Plan") was
adopted by the Board of Directors and approved by Grant's stockholders in
December 1997. The Incentive Plan was amended on three occasions to increase the
numbers of shares reserved for issuance, which presently is 2,250,000 shares.
The Incentive Plan provides for the grant to officers (including officers who
are also directors), employees, consultants and non-employee directors of Grant
and its subsidiaries. These individuals may be granted awards of "incentive
stock options" within the meaning of Section 422 of the Internal Revenue Code of
1986, non-statutory stock options, stock appreciation rights and restricted
shares and deferred shares of Grant common stock.

     The Board of Directors, or a committee of the Board of Directors consisting
of at least two non-employee directors, is required to administer the Incentive
Plan. The Board of Directors currently administers the plan and decides to whom
awards may be granted, the type of award to be granted and determine, as
applicable, the number of shares to be subject to each award, the exercise price
and the vesting. In making such determinations, the Board of Directors will take
into account the employee's present and potential contributions to our success
and other relevant factors. As of December 31, 1999, the Board of Directors had
granted outstanding awards covering 1,766,400 shares. Options covering 800,000
shares awarded to Richard H. Ward and Stephen H. Wood have an average exercise
price of $4.25 and vest annually in equal one-third increments beginning on
February 1, 2000. All other options awarded have an average exercise price of
$5.76 per share, with a range of $4.75 to $6.84 per share. These options vest
annually in one-third increments, the first third having vested on December 31,
1998. In addition, as of March 24, 2000, a total of 57,000 restricted shares
were granted to non-employee directors, with 54,000 of such shares being
unrestricted, subject to the satisfaction of conditions set forth under the
Incentive Plan.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     On May 11, 1999, the Company entered into a loan and security agreement
with Foothill and Elliott. Under the terms of that agreement, the Company may
borrow up to $6 million through a revolving credit facility and up to $19
million through two term loans. The Company must pay interest on any such
borrowing at annual rate equal to the prime rate plus 1 1/2%. Proceeds from the
loans made under this loan agreement were used to repay all the Company's $14.8
million outstanding indebtedness to Elliott under a previous credit facility and
to provide additional liquidity and working capital to support operations. On
August 12, 1999, the loan agreement was amended to modify components of the
Company's earnings calculations under the agreement and to allow interest
payments on portions subordinated indebtedness of the Company purchased by
Elliott. On September 23, 1999, the loan agreement was amended to increase the
maximum principal amount of indebtedness under the Foothill term loan to $11.67
million and to revise the repayment schedule of that loan. On February 14, 2000,
the credit facility was further increased to $29 million by increasing
commitments under the revolving facility to $10 million and increasing the term
loan back to the original outstanding balance of $11.5 million.

     Between August 16, 1999 and January 5, 2000 the Company issued a total of
149,000 shares of Exchangeable Preferred Stock to Elliott at a price of $100 per
share. The proceeds from the sale of the Exchangeable Preferred Stock totaled an
aggregate of $14,900,000 and were used to provide the Company with additional
working capital. Additionally, the Company issued 677 shares, 2,252 shares and
1,265 shares of Exchangeable Preferred Stock to Elliott as of October 1, 1999,
January 1, 2000 and February 7, 2000, respectively, as dividends on the
Company's Exchangeable Preferred Stock payable on those dates.

     On January 19, 2000, pursuant to a registration statement originally filed
on October 28, 1999 and declared effective on January 12, 2000, $56,320,000 of
Senior Notes held by Elliott and Westgate, together with $2,364,000 of accrued
and unpaid interest thereon, were exchanged for 389,722 shares of Convertible
Preferred Stock.

     On February 7, 2000, the Company exchanged all the outstanding Exchangeable
Preferred Stock owned by Elliott, 153,194 shares, for an equal number of shares
of Convertible Preferred Stock having a liquidation preference of $100 per
share.

     During 1999, the Company performed data acquisition and processing services
for an affiliated oil and gas exploration and production company. Further, this
affiliated company has participated as an underwriter in one of the Company's
multi-client data library programs. Revenues for these services were
approximately $4,090,000 for 1999 and related accounts receivables outstanding
at December 31, 1999 was $1,600,000. Management of the Company believes such
operations were conducted under terms and conditions comparable to third-party
customers.

position of Grant Geophysical, Inc. and its subsidiaries at December 31, 1999
and 1998, and the results of their operations and their cash flows for the years
then ended in conformity with accounting principles generally accepted in the
United States. 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 of these

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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

flows of GGI Liquidating Corporation and subsidiaries for the nine month period
ended September 30, 1997, in conformity with generally accepted accounting
principles.

     The accompanying consolidated financial statements and financial statement
schedule have been prepared assuming that GGI Liquidating Corporation will
continue as a going concern which contemplates among other things, the
realization of assets and liquidation of liabilities in the ordinary course of
business. As discussed in Note 1 to the consolidated financial statements, GGI
Liquidating Corporation (the Petitioning Company) filed a voluntary petition for
reorganization under chapter 11 of the United States Bankruptcy Code on December
6, 1996. The chapter 11 case of the Petitioning Company is administered by the
United States Bankruptcy Court for the District of Delaware (the "Court"). The
Petitioning Company is operating the business as debtor-in-possession which
requires certain of its actions to be approved by the Court. In September 1997
the Court approved the "Second Amended Plan of Reorganization" (the "Plan")
filed by GGI Liquidating Corporation. The Plan was consummated on September 30,
1997, with the purchase by Grant Geophysical, Inc. of substantially all of the
assets and the assumption of certain liabilities of GGI Liquidating Corporation.
GGI Liquidating Corporation is currently in liquidation and will distribute all
of its assets pursuant to the Plan. Upon the completion of its asset
distribution, GGI Liquidating Corporation will dissolve and cease to exist. The
consolidated financial statements and financial statement schedule do not
include any adjustments relating to the recoverability and classification of
reported asset amounts or the amounts and classification of liabilities that
might result from the Plan and the distribution of assets pursuant thereto.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       DECEMBER 31, 1997, 1998, AND 1999

(1) BASIS OF PRESENTATION

     Grant Geophysical, Inc., a Delaware corporation (together with its
subsidiaries, "Grant," or the "Company"), is a leading provider of seismic data
acquisition services in land and transition zone environments in selected
markets, including the United States and Canada. Grant also provides seismic
data acquisition services in Latin America, the Middle East and the Far East.
Through its predecessors, including GGI Liquidating Corporation ("GGI"), and its
acquired subsidiary, Solid State Geophysical, Inc. ("Solid State"), together
with their respective subsidiaries, the Company has participated in the seismic
data acquisition services business in the United States, Canada, Latin America,
the Far East, Middle East, and Africa.

     Effective September 30, 1997 ("the Effective Date"), in connection with the
plan of reorganization (the "Plan"), Grant Geophysical, Inc. ("Grant"), which
was formerly known as Grant Acquisition Corporation, acquired substantially all
of the assets and assumed certain liabilities of GGI Liquidating Corporation
("GGI"), which was formerly known as Grant Geophysical, Inc. Elliott Associates
L.P. ("Elliott") and Westgate International, L.P. ("Westgate") (collectively
known as the "Principal Stockholders") owned 85.4% and 84.6% of the issued and
outstanding common stock of Grant at December 31, 1998 and 1999. Westgate owned
all of the preferred stock that was outstanding in 1998. This preferred stock
was redeemed on June 5, 1998 and all authorized shares have been canceled.
Elliott owned all of the outstanding shares of the 8% Exchangeable Preferred
Stock at December 31, 1999. The general partners of Elliott are Paul E. Singer
and Braxton Associates, L.P. The general partner of Westgate is Hambledon, Inc.,
a corporation controlled by Braxton Associates, L.P.. Elliott and Westgate are
each managed by Stonington Management Corporation, a corporation controlled by
Mr. Singer. For financial statement purposes, the purchase of GGI's assets by
Grant was accounted for as a purchase acquisition. The purchase price was
allocated between the fair value of the GGI assets purchased and liabilities
assumed, and Grant recorded goodwill of approximately $21.3 million. The effects
of the acquisition are reflected in Grant's assets and liabilities as of the
effective date.

     The acquisition of Solid State Geophysical, Inc. ("Solid State") by Grant
during the fourth quarter of 1997 occurred in two parts: the acquisition of the
majority interest and the acquisition of the minority interest. As of September
30, 1997 the Principal Stockholders owned a controlling interest in both Solid
State (approximately 64%) and Grant (100%). As such, at that date, the Principal
Stockholders were deemed to have transferred their ownership in Solid State to
Grant. The acquisition of the majority interest in Solid State was accounted for
as an exchange of ownership interests between entities under common control, and
the assets and liabilities of Solid State were transferred to Grant's Financial
Statements at historical cost in a manner similar to a pooling-of-interests. The
acquisition of the unaffiliated minority interest began in November 1997 when
Grant initiated a tender offer (the "Tender Offer") for all the outstanding
common shares of Solid State not held by Grant. In connection with the Tender
Offer, the Principal Stockholders transferred their ownership of Solid State to
Grant and agreed to loan Grant $15.8 million to pay for the shares tendered in
the Tender Offer. The Tender Offer expired on December 19, 1997 and the
acquisition was completed on December 23, 1997, after which Solid State became a
wholly owned subsidiary of Grant. The acquisition of the unaffiliated minority
interest in Solid State was accounted for as a purchase, resulting in
approximately $15.3 million in goodwill.

     As a result of the aforementioned transactions, Grant's consolidated
balance sheet as of December 31, 1998 and December 31, 1999 and statement of
operations and cash flows for the three months ended December 31, 1997 and the
years ended December 31, 1998 and 1999 are presented using Grant's new basis of

accounting, while the consolidated statements of operations and cash flows for
the nine months ended September 30, 1997 are presented using GGI's historical
cost basis of accounting.

     Grant purchased, effective July 1, 1998, all of the outstanding partnership
interests in Interactive Seismic Imaging ("ISI"), a seismic data processing
company, for $3.6 million in cash. Grant had been a 10% owner of ISI since its
formation in 1994, and subsequent to the July 1 acquisition, Grant integrated
the ISI operation into its domestic operational entity. The following working
capital items were acquired in the purchase: cash and cash
equivalents -- $628,000; accounts receivable -- $364,000; accounts
payable -- $43,000; and accrued expenses -- $36,000.

     Presented below is the unaudited pro forma effect of the combination of
Solid State and Grant. Pro forma adjustments have been made to record the
consummation of the Plan and certain related transactions, the issuance of a
subordinated note in exchange for 9,571 shares of Grant preferred stock, the
Solid State acquisition, (which includes the transfer of shares of Solid State
stock to Grant by the Principal Stockholders), and the acquisition of the
unaffiliated minority interest of Solid State, which was accounted for as a
purchase. The unaudited pro forma information gives effect to the aforementioned
transactions as if they were completed as of January 1, 1997.

     On December 6, 1996 (the "Petition Date"), GGI filed for protection under
the United States Bankruptcy Code and began its reorganization under the
supervision of the Bankruptcy Court. The reorganization was precipitated by
several factors, including overly rapid and under-financed expansion in the
United States and Latin American markets, costs related to the development of a
proprietary data recording system and poor operational results in the United
States and certain international markets. These factors impaired GGI's ability
to service its indebtedness, finance its existing capital expenditure
requirements and meet its working capital needs. In addition, GGI was unable to
raise additional equity, causing a disproportionate reliance on debt financing
and equipment leasing. In connection with the reorganization, GGI replaced its
senior management, disposed of unprofitable operations and developed the Plan,
which was consummated on September 30, 1997 (the "Effective Date") with the
purchase by Grant of substantially all of the assets and the assumption of
certain liabilities of GGI. GGI is currently in liquidation and will distribute
all of its assets pursuant to the Plan. Upon the completion of its asset
distribution, GGI will dissolve and cease to exist.

     Grant is a holding company with no independent operations other than its
investments in its subsidiaries. Grant Geophysical Corp., Grant Geophysical do
Brasil Ltda., Grant Geophysical (Int'l), Inc., P.T. Grant Geophysical Indonesia,
Recuros Energeticos Ltda., Advanced Seismic Technology, Inc., Solid State
Geophysical Inc., Solid State Internacional Ingenieria C.A., Solid State
Geophysical Corp., and SSGI Acquisition Corp. (the "Subsidiary Guarantors")
represent all of the indirect and direct wholly owned subsidiaries of Grant.
Grant conducts all of its operations through its subsidiaries. The Senior Notes
(see Note 7) are fully, unconditionally, jointly and severally guaranteed by the
Subsidiary Guarantors. Management has determined that information presented by
separate financial statements of the Subsidiary Guarantors is not material to
investors.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Going Concern Considerations -- GGI

     The accompanying financial statements of GGI have been prepared on a going
concern basis, which contemplates the realization of assets and the liquidation
of liabilities in the ordinary course of business. As described earlier, GGI is
in the process of distributing its assets pursuant to the Plan and will be
dissolved. The consolidated financial statements do not include any adjustments
relating to the recoverability and classification of reported asset amounts or
the amounts and classification of liabilities that may result from the Plan and
the distribution of assets pursuant thereto.

  Principles of Consolidation

     Each of the consolidated financial statements include the accounts of GGI
or Grant and all of their respective majority-owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated.

  Minority Interest

     The minority interest reflected in the Consolidated Statements of
Operations was computed based on the minority ownership percentage in Solid
State outstanding through December 23, 1997, the date of Grant's acquisition of
the remaining minority interest in Solid State.

  Revenues

     Revenue from non-cancelable exclusive and non-exclusive seismic surveys is
recognized in accordance with the percentage of completion method of accounting
based upon costs incurred as a percentage of total estimated costs. Revenue from
cancelable exclusive seismic surveys is recognized as data are acquired and
become chargeable to the customer. Anticipated losses on survey contracts are
recognized when such losses are determinable.

     Revenue from the licensing of multi-client data surveys is recognized when
the Company obtains a non-cancelable commitment from the customer.

     Revenue from the Company's data processing services is recognized as the
services are performed.

  Cash and Cash Equivalents

     For purposes of the consolidated statement of cash flows, all highly liquid
investments with an original maturity of three months or less are considered to
be cash equivalents. Such investments totaled $2,880,000 and $351,000 at
December 31, 1998 and 1999, respectively.

  Restricted Cash

     At December 31, 1998 and 1999, restricted cash included certificates of
deposit totaling $106,000 and $17,000, respectively, which were pledged as
collateral for letters of credit.

</TABLE>

  Inventories

     Inventories, which consist primarily of miscellaneous supplies, are stated
at the lower of cost or market. Cost is determined using the specific
identification method.

  Work in Process

     Expenses related to the work in progress of seismic crews are deferred and
recognized over the performance of the contract.

  Mobilization Cost

     Transportation and other expenses incurred prior to commencement of
geophysical operations in an area, that would not have been incurred otherwise,
are deferred and amortized over the lesser of the term of the related contract
or backlog of contracts in that area or one year.

  Property, Plant and Equipment

     Property, plant and equipment are stated at cost. Plant and equipment under
capital leases are stated at the present value of future minimum lease payments
at the inception of the lease.

     Depreciation is provided principally by the straight-line method over the
estimated useful lives of the various classes of assets as follows:

     Plant and equipment held under capital leases are amortized by the
straight-line method over the shorter of the lease term or estimated useful life
of the asset. Expenditures for maintenance and repairs are charged to
operations. Betterments and major renewals are capitalized. Amortization of
assets recorded under capital leases is included with depreciation and
amortization expense.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Multi-Client Data Library

     The costs incurred in acquiring and processing multi-client seismic data
owned by the Company are capitalized. During the twelve-month period beginning
at the completion of the acquisition and processing of each multi-client survey,
costs are amortized based on revenues from such survey as a percentage of total
estimated revenues to be realized from such survey. Thereafter, amortization of
remaining capitalized costs is provided at the greater of the percentage of
realized revenues to total estimated revenues or straight line over four years.
Amortization expense associated with the Company's multi-client data library was
$1.5 million and $3.3 million for the years ended December 31, 1998 and 1999,
respectively. As of December 31, 1998 and 1999, accumulated amortization related
to the Company's multi-client data library was $1.5 million and $4.8 million,
respectively.

     On a quarterly basis, management estimates the residual value of each
survey, and additional amortization is provided if the remaining revenues
reasonably expected to be obtained from any survey or group of surveys are less
than the carrying value of such survey or group of surveys (see Note 3).

  Asset Impairment

     In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of", long-lived assets and certain identifiable intangibles are
written down to their current fair value whenever events or changes in
circumstances indicate that the carrying amounts of these assets are not
recoverable. These events or changes in circumstances may include but are not
limited to a significant change to the extent in which an asset is used, a
significant decrease in the market value of the asset, or a projection or
forecast that demonstrates continuing losses associated with an asset. If an
impairment is determined, the asset is written down to its current fair value
and a loss is recognized (see Note 3).

  Goodwill

     Goodwill, representing the excess of purchase price over fair value of net
assets acquired, is amortized on a straight-line basis over the expected periods
to be benefited. Accumulated amortization was approximately $1,723,000 and
$3,238,000 as of December 31, 1998 and 1999, respectively. The Company assesses
the recoverability of this intangible asset by determining whether the
amortization of the goodwill balance over its remaining life can be recovered
through undiscounted future operating cash flows of the acquired operation. The
amount of goodwill impairment, if any, is measured based on projected discounted
future operating cash flows using a discount rate reflective of Grant's average
cost of funds. The assessment of the recoverability of goodwill will be impacted
if estimated future operating cash flows are not achieved. The goodwill created
in the purchase of GGI's assets and the purchase of the remaining interest in
ISI is being amortized over 30 years and the goodwill created in the acquisition
of Solid State's minority interest is being amortized over 20 years.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

                  GGI LIQUIDATING CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The more significant areas requiring the use of management estimates relate
to expected future sales associated with the Company's multi-client data
library, estimated future net cash flows related to long-lived assets and
valuation allowances for deferred tax assets. Actual results could differ
materially from these estimates making it reasonably possible that a change in
these estimates could occur in the near term.

  Reorganization Costs

     Reorganization costs consisting of professional fees and similar types of
expenditures directly related to GGI's Chapter 11 bankruptcy proceeding were
expensed as incurred. During the nine months ended September 30, 1997, GGI
incurred approximately $3,543,000 of reorganization costs.

  Foreign Exchange Gains and Losses

     The United States ("U.S.") dollar is the Company's primary functional
currency in all foreign locations with the exception of its Canadian
subsidiaries. Accordingly, those foreign entities (other than Canada) translate
property and equipment (and related depreciation) and inventories into U.S.
dollars at the exchange rate in effect at the time of their acquisition while
other assets and liabilities are translated at year-end rates. Operating results
(other than depreciation) are translated at the average rates of exchange
prevailing during the year. Remeasurement gains and losses are included in the
determination of net income and are reflected in other income (expense) (See
Note 15). The Canadian subsidiaries use the Canadian dollar as their functional
currency and translate all assets and liabilities at year-end exchange rates and
operating results at average exchange rates prevailing during the year.
Adjustments resulting from the translation of Canadian assets and liabilities
are recorded in the accumulated other comprehensive loss account in
stockholders' equity.

  Income Taxes

     Under the asset and liability method of SFAS No. 109, deferred tax assets
and liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. Under SFAS No. 109, the effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date. The Company considers the undistributed earnings of
its foreign subsidiaries to be permanently reinvested. The Company has not
provided deferred U.S. income tax on those earnings, and it is not practicable
to estimate the amount of additional tax that might be payable should these
earnings be remitted or deemed remitted as dividends or if the Company should
sell its stock in these foreign subsidiaries.

  Income (Loss) Per Common Share

     In accordance with Statement of Financial Accounting Standards No. 128,
"Earnings per Share," basic income (loss) per common share is computed based
upon the weighted average number of common shares outstanding during each period
without any dilutive effects considered. Diluted income (loss) per common share
reflects dilution for all potentially dilutive securities, including warrants
and convertible securities. The income (loss) is adjusted for cumulative
preferred stock dividends in calculating net income (loss) attributable to the
common shareholder. Earnings per share data have not been presented for GGI as
this information is not meaningful.

  Stock-Based Compensation

     As allowed by SFAS No. 123, "Accounting of Stock Based Compensation" the
Company has elected to continue to follow the accounting prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," whereby compensation expense is recognized only in situations where
stock compensation plans award intrinsic value to recipients at the date of
grant, rather than following the fair value method of SFAS No. 123. Pro forma
disclosure of the estimated effects on net income and income (loss) per common
share had the fair value method prescribed by SFAS No. 123 been followed is
included in Note 10.

     In 1998, the Company adopted SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information." SFAS 131 supersedes SFAS 14, "Financial
Reporting for Segments of a Business Enterprise," replacing the "industry
segment" approach with the "management" approach. The management approach
designates the internal organization used by management for making operating
decisions and assessing performance as the basis for determining the Company's
reportable segments. SFAS 131 also requires disclosures about products and
services, geographic areas and major customers. The adoption of SFAS 131 did not
affect results of operations or financial position but did affect the disclosure
of segment information (see Note 4).

  Reclassifications

     Certain amounts previously reported have been reclassified to conform to
current year financial statement presentation.

  Current Industry Conditions

     The Company competes in a highly competitive sector of the oil and gas
services industry. The Company's business depends in large part on the
conditions of the oil and gas exploration and production industry sector, and
specifically on capital expenditure levels of the Company's customers directed
toward seismic data acquisition and processing. As a result of the decline in
oil and gas prices beginning late in the third quarter of 1998 and continuing
into the first quarter of 1999, the level of overall oil and gas industry
activity declined significantly in 1999 from levels experienced in recent years.
The Company's results of operations and cash flows, both domestically and in
certain international regions, have been and will continue to be adversely
affected should capital spending levels by the Company's customers continue at
depressed levels and thereby reduce demand for the Company's services.

     As indicated in the accompanying Consolidated Statements of Operations, the
Company sustained a significant loss in 1999. As discussed in Note 20,
subsequent to December 31, 1999, the Company completed the exchange of
approximately $56.3 million of long-term debt and related accrued interest of
approximately $2.4 million for the Company's 8% Convertible Preferred Stock.
Further, the Company's senior credit facility was modified and increased to
provide additional working capital sources. Management's recent actions have
also included downsizing personnel and operations to meet reduced market demand
and slow down the cash drain caused by operating losses. Further cost reduction
initiatives are being reviewed and capital expenditures are being examined for
necessity and priority. Management believes the recent steps it has taken will
allow the Company to meet its debt service requirements and provide sufficient
cash flows to operate, realize its assets and discharge its liabilities in the
normal course of business.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company believes a prolonged
depression in oil and gas exploration activity will have a material adverse
effect on the Company's financial position and results of operations.

(3) CHARGE FOR ASSET IMPAIRMENT

  Grant

     In the fourth quarter of 1997, certain assets of Solid State were written
down to reflect their fair value in accordance with the Company's asset
impairment policy. Fair market value was determined by discounting the assets'
projected future cash flows. Accordingly, Grant recorded a $6,369,000 special
charge for asset impairment in the fourth quarter of 1997. This charge primarily
consisted of $5,869,000 relating to Solid State's multi-client data library and
$500,000 relating to miscellaneous assets held by Solid State.

     In the fourth quarter of 1998, the Company wrote down certain
non-productive fixed assets to fair market value in the amount of $564,000 and
certain multi-client data surveys in the amount of $3.2 million

     In the third and fourth quarters of 1999, the Company wrote down certain
multi-client data surveys in the amounts of $4.7 million and $302,500,
respectively.

     The impairments in 1997, 1998 and 1999 were due to revised estimates of
future licensing prospects for such data due to reduced interest in the area by
oil and gas companies and depressed exploration activities in the oil and gas
exploration and production industry sector.

(4) SEGMENT INFORMATION

     Grant has determined that its reportable segments are those based on the
Company's method of internal reporting, which disaggregates its one
product/service line (geophysical services) into four geographic regions: the
United States, Canada, Latin America and the Far East.

     The accounting policies of the segments are the same as those described in
Note 2 - Summary of Significant Accounting Policies for Segment Information.
Grant evaluates the performance of its segments and allocates resources to them
based on operating income (loss). There are no intersegment revenues.

     A valuation allowance is established when it is more likely than not that
some portion or all of the deferred tax assets will not be realized. The
valuation allowance is then adjusted when the realization of deferred tax assets
becomes more likely than not. Adjustments are also made to recognize the
expiration of net operating loss carryforwards, with equal and offsetting
adjustments to the related deferred tax asset. The increase in the valuation
allowance during 1998 and 1999 of approximately $997,000 and $18,091,000,
respectively, resulted primarily from current period net operating losses.

     As of December 31, 1999, Grant has U.S. ($71,383,000) and non-U.S.
($10,791,000) net operating loss carryforwards of approximately $82,174,000.
Such tax loss carryforwards expire in varying amounts during the periods from
2000 through 2011 and 2016 through 2019, except for $1,966,000 of the non-U.S.
loss which has an indefinite carryforward period.

     Internal Revenue Service regulations restrict the utilization of U.S. net
operating loss carryforwards and other tax benefits for any company in which an
"ownership change" (as defined in Section 382 of the Internal Revenue Code) has
occurred. Grant has concluded that two "ownership changes" have occurred. The
first occurred in connection with the GGI reorganization on September 30, 1997.
The utilization of GGI's U.S. net operating loss carryforwards existing at this
date is limited to approximately $704,000 per year. The second "ownership
change" occurred on December 30, 1997 as a result of the reorganization of Solid
State. The utilization of Solid State's U.S. net operating losses at this date
is limited to approximately $125,000 per year.

     On March 18, 1998, all of the then outstanding debt of Grant, with the
exception of approximately $3.6 million relating to one capital lease obligation
and one note payable, was paid off with the proceeds of the Senior Notes (see
below).

     On October 1, 1997, Grant and Elliott entered into a credit facility (the
"Credit Facility") providing for a revolving loan facility under which Grant
could borrow up to an aggregate principal amount of $5 million. On December 18,
1997, the credit facility was amended to provide for a term loan of $15.8
million in addition to the revolving loan. The proceeds of the term loan were
used by Grant to purchase all of the stock of Solid State not already owned by
Grant (see Note 1). This original credit facility was due to expire on March 31,
1999, at which time all obligations of Grant under the credit facility were due
and payable. In connection with the redemption of the cumulative pay-in-kind
preferred stock, par value $.001 per share ("Preferred Stock") (see Note 12),
held by Westgate, Elliott agreed to amend the Credit Facility on June 5, 1998 to
increase the

maximum borrowing capacity from $5 million to $15 million and to extend the term
of the facility from March 31, 1999 to March 31, 2000. In April 1999, the Credit
Facility was further extended to $20 million. The loans under the Credit
Facility were collateralized by all of Grant's assets and a pledge by Grant of
certain notes and all the outstanding shares of capital stock of its
subsidiaries. Each subsidiary of Grant executed a guaranty in favor of Elliott,
each of which guaranteed payment of all Grant's obligations owed to Elliott
under the Credit Facility. Each subsidiary pledged its assets in favor of
Elliott to secure its obligations under its respective guaranty. The Credit
Facility contained restrictions which, among other things, prohibited Grant's
right to pay dividends and limited its right to borrow money, purchase fixed
assets or engage in certain types of transactions without the consent of the
lender. The $15.8 million term loan was paid in full on February 18, 1998 with
the proceeds of the Senior Notes (See below). At December 31, 1998, the Company
was in technical violation of a covenant in the Credit Facility which limited
the capital expenditures for any one year to a maximum of $14 million. The
Company obtained from Elliott a consent and waiver to the default, effective
December 31, 1998. In addition, the Credit Facility limits the Company from
taking, without the consent of the lender, certain actions, including creating
indebtedness in excess of specified amounts and declaring and paying dividends.

     On May 11, 1999, the Company entered into a Loan and Security Agreement
(the "Foothill/Elliott Credit Facility") with Foothill Capital Corporation and
Elliott (collectively the "Lenders"), pursuant to which the Company could borrow
up to $6.0 million through a revolving facility and up to $19.0 million through
two term loans. Proceeds were used to repay all of the Company's outstanding
indebtedness to Elliott ($14.8 million) and to provide additional liquidity and
working capital to support the Company's operations. The Foothill/Elliott Credit
Facility imposes certain limitations on the ability of the Company and its
subsidiaries to, among other things, incur additional indebtedness, incur liens,
pay dividends or make other distributions in cash or certain property,
consummate certain asset sales, enter into certain transactions with affiliates,
merge or consolidate with any other persons or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of the assets of the
Company or its subsidiaries, make investments (as defined in the
Foothill/Elliott Credit Facility) and maintain a minimum EBITDA (earnings before
interest, tax, depreciation and amortization) level. The interest rate on the
loans is 1.5% over prime. Amounts available and outstanding at December 31, 1999
are $196,000 and $23.1 million, respectively.

     The Company's equipment notes payable and capital lease obligations
represent installment loans or capital lease obligations primarily related to
the acquisition of seismic recording equipment. These instruments, with the
exception of $3.6 million noted above, were paid in full on February 18, 1998
with the proceeds of the Senior Notes (see below).

     On February 18, 1998, Grant completed an offering of $100 million face
value 9 3/4% Senior Notes due and payable in a lump sum on February 15, 2008.
The Senior Notes bear interest from February 18, at a rate per annum set forth
above payable semi-annually on February 15 and August 15 of each year,
commencing August 15, 1998. The net proceeds to Grant from the sale of the
Senior Notes was approximately $95.2 million after deducting the Initial
Purchaser's discount and certain other estimated fees and expenses. Grant used
the proceeds to repay approximately $74.5 million of the outstanding balance of
debt ($73.0 million) and interest ($1.5 million) existing at December 31, 1997.
Total debt issue costs of $4.3 million were incurred in connection with the
offering and are being amortized over the term of the notes.

     The Senior Notes were issued under an indenture (the "Indenture") entered
into among the Company, as issuer, the Subsidiary Guarantors, and LaSalle Bank
National Association, as trustee, dated as of February 18, 1998. The Indenture
imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries (as defined in the Indenture) to, among other things, incur
additional indebtedness (including capital leases), incur liens, pay dividends
or make certain other restricted payments, consummate certain asset

(9) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     Methodology and assumptions used to assess fair value of classes of
financial instruments follows:

  Cash and short-term financial instruments

     The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable and accrued expenses approximate fair value because of the
short-term maturities of such instruments.

  Long-term notes receivable

     The fair value has been estimated using the expected future cash flows
discounted at market interest rates which approximate its carrying value.

  Long-term debt

     The carrying values of the Company's long-term debt instruments approximate
their fair values. Grant's long-term debt has been estimated based on current
quoted market prices for the same or similar issues, or on the current rates
offered to Grant for debt of the same remaining maturities.

(10) STOCK-BASED COMPENSATION

     The 1997 Equity and Performance Incentive Plan (the "Incentive Plan") was
adopted by the Board of Directors and approved by Grant's stockholders in
December 1997. The Incentive Plan was amended in September 1998 to increase the
number of shares reserved for issuance under the Incentive Plan from 1,450,000
shares of Grant Common Stock to 1,900,000 shares of Grant Common Stock and
subsequently, in February 1999, to 2,000,000 shares of Grant Common Stock. The
Incentive Plan provides for the grant to officers (including officers who are
also directors), employees, and non-employee directors of Grant and its
subsidiaries, of "incentive stock options" (within the meaning of Section 422 of
the Internal Revenue Code of 1986 (the "Code")), nonstatutory stock options,
stock appreciation rights and restricted shares. The Incentive Plan is not a
deferred compensation plan under Section 401(a) of the Code and is not subject
to the provisions of the Employee Retirement Income Security Act of 1974.

     The Incentive Plan is required to be administered by the Board of Directors
or by a committee of the Board of Directors consisting of at least two
non-employee directors. The Board of Directors or its designated committee will
select the employees and non-employee directors to whom awards may be granted
and the type of award to be granted and determine, as applicable, the number of
shares to be subject to each award, the exercise price and the vesting. In
making such determinations, the Board of Directors or its designated committee
will take into account the employee's present and potential contributions to the
success of the Company and other relevant factors. As of December 31, 1999,
awards covering 1,766,400 shares have been made by the Board of Directors.
During 1999, there were 613,800 option cancellations due to terminations. The
1998 awards include 966,400 non-statutory stock options that will vest annually
in equal one-third increments beginning on December 31, 1998. All such options
were granted at a price equal to or in excess of the then estimated fair market
value of the Company's stock at the date of grant. Such options have an average
exercise price of $5.76 per share (range of $4.75 to $6.84 per share), subject
to adjustment in certain circumstances. The 1999 awards consist of 800,000
non-statutory stock options that will vest annually in equal one-third
increments beginning on February 1, 2000. Such options have an exercise price of
$4.25 per share. In addition, 9,000 restricted shares (54,000 total restricted
shares, 36,000 in 1998 and 18,000 in 1999) were granted to each non-employee
director subject to the satisfaction of certain conditions set forth under the
Incentive Plan. The Company recognized approximately $150,000 and $54,000 in
compensation expense in

     The Company applies Accounting Principles Board Opinion 25 in accounting
for its share-based compensation plans and has adopted the disclosure-only
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation."
Accordingly, no compensation cost has been recognized under these plans, with
the exception noted above, because as of the measurement date, which in this
case is the grant date, the exercise price of granted options is equal to or in
excess of the fair value of the underlying shares. Had compensation cost for the
Company's share-based compensation plans been determined based on the fair
values of the options granted after January 1, 1998, consistent with the
provisions of SFAS No. 123, the Company's net loss and loss per share would have
increased as follows:

     The weighted average fair value of options granted during 1998 and 1999 was
$1.94 and $0, respectively. The fair value of each option award is estimated on
the grant date using the Black-Scholes option pricing model with the following
weighted average assumptions used for grants in 1998 and 1999: expected
volatility of zero, risk-free interest rate of 5.5% and 4.7%, expected lives of
ten and five years, respectively, and a dividend yield of zero.

  GGI

     Pursuant to the Plan, GGI's capital stock was canceled on the Effective
Date. As a result, GGI's Amended 1989 Long-Term Incentive Plan was also
canceled. Therefore, the effects of SFAS No. 123 for the nine months ended
September 30, 1997 have not been presented.

  Grant

     During the three months ended December 31, 1997 Grant did not grant any
awards under the 1997 Equity and Performance Plan. Therefore, the effects of
SFAS No. 123 for the three months ended December 31, 1997 have not been

(11) EMPLOYEE BENEFIT PLANS

  Employee Retirement Savings Plan

     GGI had established a defined contribution plan covering substantially all
U.S. and certain foreign employees whereby participants could elect to
contribute between 1% and 15% of their annual salary. Participants could not
make contributions in excess of $10,000 per year (as adjusted annually by the
cost of living adjustment factor). On the Effective Date, GGI assumed and
assigned the plan to Grant. Under the plan, the employer may contribute, on a
discretionary basis, one-half of the participant's contribution percentage up to
6% (limited to 3% of any employee's annual salary). The plan was amended in June
1997 to eliminate the employer's option to contribute common stock so that
discretionary contributions may be made only in the form of cash. Cash
contributions to the plan by Grant for the three-month period ended December 31,
1997 and years ended December 31, 1998 and 1999 totaled $39,000, $196,000 and
$94,000, respectively.

  Other Postretirement Benefits

     GGI sponsored a defined contribution postretirement plan which, pursuant to
the Plan, was assumed by GGI and assigned to Grant. The plan is contributory and
is structured to provide medical coverage for eligible retirees and their
dependents (as defined in the plan). Generally, employees who have completed 10
years of continuous service with the Company, are between 55 and 64 years of
age, and are ineligible for Medicare are eligible for plan participation.
Liabilities for postretirement health care benefits are not material to the
Company's results of operations or financial position.

  Grant

     PREFERRED STOCK

     Grant had authorized 20,000 shares of cumulative pay-in-kind preferred
stock (the "Cumulative Preferred Stock"), par value $0.001 per share, with a
liquidation preference of $1,000 per share of which 10,000 shares were
outstanding . Dividends accrued and were cumulative from September 30, 1997, the
date on which such shares were issued. Dividends accrued at an annual rate of
10.5% of the liquidation value and were payable annually on September 30 of each
year.

     On June 5, 1998 the Company redeemed the 10,000 shares of Cumulative
Preferred Stock, held by Westgate, representing the liquidation amount of all
such outstanding shares of Cumulative Preferred Stock, together with all
accumulated, accrued and unpaid dividends of approximately $702,000, in the
aggregate amount of $10.7 million. Upon redemption, the Cumulative Preferred
Stock was canceled, retired and eliminated from the shares that the Company is
authorized to issue.

     Grant has authorized 150,000 shares of 8% exchangeable pay-in-kind
preferred stock (the "Exchangeable Preferred Stock"), par value $0.001 per
share, with a liquidation preference of $100 per share, of which 149,677 shares
were outstanding as of December 31, 1999. Dividends accrued at an annual rate of
8%, of the liquidation value and paid quarterly on April 1, July 1, October 1
and January 1. Unpaid dividends associated with the Exchangeable Preferred Stock
at December 31, 1999 were approximately $225,000. The shares were issued between
August 16 and December 29, 1999 and dividends accrued from the issuance date.

     On October 25, 1999, holders of greater than a majority of the outstanding
common stock voting power of the Company acted, by written consent, to further
amend the Amended and Restated Certificate of Incorporation to decrease the
number of authorized aggregate shares of capital stock of the Company from
60,000,000 to 55,000,000 shares thus decreasing the number of authorized shares
of the Company's preferred stock from 10,000,000 to 5,000,000 shares.

     See Note 20 -- Subsequent Events for discussion of the issuance of shares
of the Company's 8% Convertible Preferred Stock for outstanding shares of the
Company's Exchangeble Preferred Stock and a portion of the Company's outstanding
Senior Notes.

  Common Stock

     At December 31, 1999, Grant had authorized 50,000,000 shares of common
stock, par value $.001 per share, of which 14,544,055 shares are issued and
outstanding. On September 30, 1999, the Company entered into an Asset Purchase
Agreement, effective October 30, 1999 for the purchase of certain seismic
acquisition equipment. The purchase price for the assets included the issuance
of 100,000 shares of common stock, valued at $3.00 per share, which management
considers fair market value at such time. The changes in common

(13) CONTINGENCIES

     On December 11, 1997, certain holders of interests under the Plan, acting
through an "ad hoc" committee, (the "Plaintiffs") commenced a lawsuit in the
Bankruptcy Court against Grant, GGI, Elliott, Westgate and Solid State. The
lawsuit alleged that (i) GGI and Elliott breached their obligations under the
Plan by seeking to complete the Solid State acquisition prior to commencing an
offering of the Company's common stock, par value $.001 per share ("Common
Stock"), to certain holders of claims and other interests under the Plan (the
"Subscription Offering"), (ii) the Solid State acquisition and certain related
transactions were unfair to the Plaintiffs because they diluted the value of the
common Stock to be issued to them under the Subscription Offering and impaired
the Company's equity value and (iii) the Solid State acquisition and certain
related transactions could and should have been, but were not, adequately
disclosed in the disclosure statement filed with the Bankruptcy Court regarding
the Plan. The Plaintiffs requested (i) compensatory and punitive damages in an
unstated amount and (ii) revocation of the Plan. In addition, the Plaintiffs
sought to enjoin completion of the Solid State acquisition and certain related
transactions pending a trial on the merits. This request for injunctive relief
was denied by the Bankruptcy Court on December 16, 1997, and was denied on
appeal by the United States District Court for the District of Delaware on
December 19, 1997. During the discovery process for the lawsuit, the parties
began to discuss a settlement. These discussions led to a settlement of the
lawsuit on June 19, 1998 (the "Settlement"). Under the terms of the Settlement,
in exchange for a full and complete release of all of the Plaintiffs' claims
against Elliott, Westgate, the Company and their respective officers, directors,
partners, employees, agents, subsidiaries, affiliates, successors and assigns
relating to or arising out of the bankruptcy proceedings of GGI and a dismissal
of the lawsuit, Elliott paid the Plaintiffs $150,000 for reimbursement of legal
expenses and permitted the Plaintiffs to purchase Grant Common Stock in the
Subscription Offering at a discounted subscription purchase price of $4.75 per
share. The Company recorded $635,000 in litigation expense associated with the
Settlement, representing the cash paid by Elliott and the $0.25 discount
permitted the Plaintiffs to purchase Grant Common Stock in the Subscription
Offering. In addition, Elliott agreed to indemnify Grant against any liability
that they may incur in connection with the lawsuit. Nevertheless, other eligible
subscribers in the Subscription Offering who did not execute a release in
connection with the Subscription Offering could commence other lawsuits related

the Plan, which may not be subject to indemnification by Elliott, and which
could have an adverse effect on Grant's business, reputation, financial
position, results of operations or cash flows.

     In October 1998, Zurich American Insurance Company ("Zurich") made a demand
on Grant for the payment of $694,000 claimed to be due Zurich under the terms of
certain insurance policies issued by Zurich to GGI in 1996, which policies were
allegedly assumed by Grant at the conclusion of its bankruptcy reorganization in
1997. A settlement was agreed to by the parties subject only to the execution of
a definitive Settlement Agreement and funding of the settlement at a cost to
Grant of $290,000. This amount was accrued at December 31, 1998 and paid in
1999.

     Grant is involved in various claims and legal actions arising in the
ordinary course of business. GGI is involved in various claims and legal actions
arising in the bankruptcy and related to the Plan. Management of GGI and
management of Grant are of the opinion that none of the claims and actions are
likely to have a material adverse impact on GGI's or Grant's financial position,
results of operations or cash flows.

     The Court generally has jurisdiction over all of GGI's property, as defined
in section 541 of the Bankruptcy Code, held on the Petition Date or acquired
thereafter. GGI may not engage in transactions except pursuant to the Plan
without prior approval of the Court.

(14) RELATED PARTY TRANSACTIONS

     A former senior vice resident of Grant loaned approximately CDN $500,000
for a two-year term at 10% interest to an entity in which the Company held, at
the time, a 18% common equity interest. Additionally, Grant owned $268,000 of
redeemable, cumulative preferred shares in the same entity. Currently, the
Company holds a 14.5% common equity and no preferred shares. During 1998, Grant
recorded a $271,000 write-down to reduce the carrying value of its investment in
this entity to zero due to the entity's uncertain financial condition. The
Company has in the past used this entity periodically to perform survey
services. The senior vice president resigned in January 1998. During the three
months ended December 31, 1997, Grant paid approximately $364,000 to this
entity.

     The Company's Chairman of the Board ("Chairman") is an officer of an
affiliate of the Principal Stockholders of Grant. On April 28, 1998, Elliott
granted to the Chairman options to purchase 100,000 shares of Common Stock from
Elliott. Additionally, the Chairman has entered into a consulting agreement,
dated April 28, 1998, with Grant (the "Consulting Agreement") which provides for
an annual consulting fee of $100,000 for as long as he remains Chairman. Under
the Consulting Agreement, the Chairman was also granted options by the Company
to purchase 50,000 shares of Common Stock under the Incentive Plan at exercise
prices equal to or in excess of the fair market value of the Company's stock on
date of grant. These options will vest annually in equal one-third increments
beginning on December 31, 1998, and have an average exercise price of $6.07 per
share.

     See Note 19 for a discussion of the subscription offering and Notes 7, 12
and 20 for debt financing with Elliott.

     During 1999, the Company performed data acquisition and processing services
for an affiliated oil and gas exploration and production company. Further, this
affiliated company has participated as an underwriter in one of the Company's
multi-client data library programs. Revenues for these services were
approximately $4,090,000 for 1999 and related accounts receivable outstanding at
December 31, 1999 was $1,600,000. Management of the Company believes such
operations were conducted under terms and conditions comparable to third-party
customers.

(19) SUBSCRIPTION OFFERING

     Pursuant to the Plan, the Company was required to conduct a subscription
offering (the "Subscription Offering") of 4,750,000 shares of Grant Common Stock
to certain holders of claims and other interests under the Plan for an aggregate
purchase price of $23,750,000. The Plan provided that (i) Eligible Class 5 Claim
Holders; (ii) Eligible Class 7 Interest Holders; and (iii) Eligible Class 8
Interest Holders, each as defined in the Plan (Collectively, the "Eligible
Subscribers") could participate in the Subscription Offering. Because Elliott
and certain of its affiliates, as interest holders under the Plan, were entitled
to purchase 1,356,231 shares of Grant Common Stock in an offering by the
Company, the Principal Stockholders offered the balance of such shares of Grant
Common Stock to the Eligible Subscribers pursuant to the Subscription Offering.
The Company registered the shares of Grant Common Stock with the Commission
pursuant to the Subscription Offering. The registration statement became
effective on July 7, 1998, and rights to subscribe for shares of Common Stock
pursuant to the Subscription Offering expired if not exercised on August 24,
1998. As a result of the Subscription Offering a total of 2,080,722 of shares
were subscribed. The total purchase price for these shares received by the
Principal Shareholders was approximately $9,918,000.

(20) SUBSEQUENT EVENTS

     Pursuant to a registration statement initially filed on October 28, 1999,
and declared effective on January 12, 2000, the Company offered to exchange (the
"Exchange Offer") $100,000,000 aggregate principal amount of its outstanding
Senior Notes due 2008 for new shares of its 8% Convertible Preferred Stock
("Convertible Preferred Stock") with an aggregate liquidation value equal to 65%
of the aggregate principal amount of the Senior Notes tendered plus 100% of the
accrued and unpaid interest thereon through the date of the exchange. On January
19, 2000, a total of $56,320,000 of the Senior Notes, together with $2,364,000
of accrued and unpaid interest, were exchanged for 389,722 shares of the
Convertible Preferred Stock. The Senior Notes exchanged represent all of the
Senior Notes previously held by Elliott and Westgate. No other Senior Notes were
tendered and the Exchange Offer expired on February 7, 2000. The Company intends
to pay dividends on the Convertible Preferred Stock in additional shares of
Convertible Preferred Stock until further notice.

     In connection with the Exchange Offer, the Company solicited consents from
the holders of its Senior Notes in order to amend definitions and to modify some
restrictive covenants in the indenture governing the Senior Notes. The consent
of holders of a majority of the outstanding principal amount of the Senior Notes
held by holders other than Grant, its subsidiaries and affiliates was required
to approve the proposed amendments to the indenture. The consent was approved on
January 19, 2000. Following the tender of the Senior Notes by Elliott and
Westgate, the Company executed a First Supplemental Indenture with LaSalle Bank
National Association, the trustee, dated January 19, 2000 that caused the
approved amendments to take effect. The Supplemental Indenture, among other
things, amended the definition of permitted indebtedness to allow for the
increase of incurred debt from $25 million to $50 million, increased additional
indebtedness from $7.5 million to $10 million and allows for the payment of
dividends on Convertible Preferred in additional shares of Convertible
Preferred.

     On January 27, 2000, the Company issued an additional 3,000 shares of
restricted common stock to a new Director.

     On February 14, 2000, the Company completed significant modifications to
the Loan and Security Agreement with Foothill and Elliott dated May 11, 1999.
The Foothill/Elliott credit facility was increased from $25 million to $29
million. This was accomplished by increasing commitments under the revolving
credit facility from $6 million to $10 million, subject to borrowing base
limitations. Additionally, the term loan, which had been reduced through
periodic payments to $10.1 million, was increased to the original outstanding
balance of $11.5 million.

     Pursuant to an agreement reached March 3, 2000, the Company agreed to
purchase the contractual interests held by a broker having exclusive
multiple-year marketing rights for certain of the Company's multi-client data
surveys. As a result of this agreement, further data sales and transfer fee
commissions will not be payable to this broker, except for two designated data
surveys. Consideration provided by the Company for the purchase of such
interests included $2.3 million cash paid at closing; a $700,000 8% promissory
note payable in 12 quarterly installments; assignment to the broker of interests
held in certain of the Company's data surveys having a carrying value of
approximately $1.2 million; and assignment of a portion of an overiding royalty
interest held by the Company in one designated data survey.

(21) PRO FORMA CONSOLIDATED BALANCE SHEET (UNAUDITED)

     The unaudited pro forma consolidated balance sheet of Grant Geophysical,
Inc. for the year ended December 31, 1999 was prepared by the Company to give
effect to the following exchange transactions completed subsequent to December
31, 1999, as discussed in Note 20:

     - the issuance of the Company's Exchangeable Preferred Stock to Elliott
       prior to the completion of the subscription offering;

     - the exchange of such shares, together with accrued and unpaid dividends
       thereon, for shares of Convertible Preferred Stock; and,

     - the completion of the exchange offer, reflecting Senior Notes
       representing 56.32% of the Company's aggregate principal amount of Senior
       Notes outstanding being exchanged for shares of the Company's Convertible
       Preferred Stock.

     The difference between the carrying value of the Senior Notes and the
Convertible Preferred Stock has been reflected as an increase to additional
paid-in-capital due to the related party nature of the exchange. With 56.32% of
the Senior Notes exchanged, the historical cost of the following line items in
the unaudited pro forma consolidated balance sheet at December 31, 1999 is
adjusted as follows:
