market value obtained by using this valuation on the 6,922,722 shares of the
voting stock held by non-affiliates of the registrant in December 1999 would
be approximately $346,136. For these purposes, the term "affiliate" is deemed
to mean officers and directors of the registrant.

PART ONE

ITEM 1. BUSINESS

GENERAL

         FIRST SEISMIC Corporation provides to its customers seismic data and
other geoscientific information that is primarily used in oil and gas
exploration and production efforts. We sell licenses to use our proprietary
information as well as information owned by others under broker and agency
arrangements to oil and gas companies. We also invest in select upstream oil
and natural gas exploration through our recently acquired wholly owned
subsidiary FORTESA Corporation, a Texas Corporation. See Note 10 to our
Consolidated Financial Statements for financial information relating to our
March 30, 1999 acquisition of FORTESA. We were originally incorporated in
Delaware in July 1990. Our data information operations are primarily
conducted through our three wholly owned subsidiaries, which are FIRST
EXCHANGE Corporation, a Delaware corporation, FIRST EXCHANGE Limited, a
United Kingdom corporation, and Blackwell Supply, Inc., d.b.a. Blackwell
Trading, Inc., a Delaware corporation.

         Since 1993, sales of licenses to use our seismic information have
substantially declined due to reduced demand for 2-D seismic data. Prior to
1993, license sales of 2D data had been the source of substantially all of
our business. In response, we have redefined our business. Our main source of
revenues since 1993 have been license sales, brokerage, packaging,
publication, and related services pertaining to diverse geoscientific
information which we seek to acquire, package, own or represent in order to
make it available for licensing to oil and gas industry exploration
customers. This geoscientific information is comprised of studies, research,
measurements, interpretations, information compilations, translations,
special reports, well data, correlations, graphical displays, databases of
values, and maps. The scientific disciplines covered by these geoscientific
information packages include geophysics, geology, geochemistry, engineering,
environmental, and regional synthesis of such information in various
combinations, all oriented towards providing exploration visibility in
specific geographic areas to our customers. We have copyrighted the completed
published materials in each geographic area of our endeavor, and our
customers license the use of this information from us for their own internal
use.

          We have made capital expenditures of over $1,000,000 in the
acquisition, processing and packaging of such geoscientific information
during the four years ended December 31, 1998 and are actively pursuing the
licensing of this data, as well as related geoscientific services which are
required by our customer base.

         As discussed in detail below under Oil & Gas Exploration and
Production Operations, we are also pursuing select opportunities in the oil &
gas exploration and production business where such endeavors complement
relationships with our suppliers, customers and co-venturers. We plan to
devote a greater percentage of our financial and other resources in the
future to oil and gas exploration and production and the promotion of
investment opportunities for the oil and gas industry at large. Management
believes that our future financial success depends largely on the success of
these related oil and gas ventures. See "Oil and gas Exploration and
Production Operations" below for a discussion of these oil and gas ventures.

SEISMIC OPERATIONS

         Historically, we have engaged in the development of a proprietary
seismic data library. Our seismic data library consists exclusively of
two-dimensional or 2D data, and was developed over a period of approximately
ten years. As of 1991 our seismic data library consisted of over 11,000 miles
of domestic 2D seismic line data. As of December 31, 1998, our seismic data
library consisted of approximately 8,500 miles of domestic and foreign 2D
seismic line data. Our library is marketed to major and independent oil and
gas companies under use-license arrangements. Additionally, we have been
involved in the sale of licenses for seismic data owned by others, under
brokerage and agency agreements. Seismic surveys and the analysis of seismic
data for the identification and definition of underground geological features
and structures are principal techniques used in oil and gas exploration and
development to determine possible locations of subsurface hydrocarbons.

         Beginning in 1992, technology that enabled geoscientists to obtain
seismic data in three dimensions ("3D") became much more cost effective and
universally available. 3D seismic data makes possible a graphic geophysical
depiction of the substrata geology from two (instead of just one, as in 2D
seismic) horizontal dimensions and one vertical dimension. This process
provides a substantially more accurate representation than 2D data and
significantly enhances the ability to evaluate the probable existence and
location of subsurface hydrocarbons.


                                      3
<PAGE>

         Accordingly, 3D seismic data became the information of choice among
our historical customers, and as a result, the demand for and the relative
value of our extensive 2D library decreased significantly. Both the volume of
2D seismic licenses sold and the prices which customers were willing to pay
for such information suffered severe downturns beginning in late 1991. While
a market remains for this information and the Company continues to engage in
this business, management believes that future prospects for growth in
ownership and marketing of 2D information are below a critical mass necessary
to be of significant commercial interest to the Company. During 1998, sales
of 2D seismic information accounted for approximately 20% of the Company's
revenues. Approximately 30% of our revenues come from associated services
such as reproduction and interpretation of such data.

GEO-TECHNICAL PUBLISHING AND SERVICES

         Cash flow from our operations since 1993 has increasingly come from
license fee and service revenue generated by our exploration and
geoscientific research, as well as geo-technical services performed directly
for our customers. In these areas, we compete on the basis of expertise in
packaging, marketing, and supplying interrelated data for a particular area
of geologic interest. We perform these functions exclusively for oil
companies, either by our preparation of direct information on an exclusive
basis for the customer, or as multi-client studies on which (i) we attempt to
retain an ownership interest in the resulting study for on-going income, and
(ii) our customer receives the right to use the compiled information for
internal use under a licensing agreement.

         We have developed and added geotechnical publications used for
multi-client sales into our data library. Typically we realize a better
margin in these products due to our partial or full ownership position in
them, as compared to information brokerage and commission revenue from data
that we do not own. Potential customers may inspect abstracts of information
and data types and determine their usefulness for a particular project via
our website at www.first-exchange.com. Our geotechnical publication products
and services tend to be more cost effective for customers than those which
they develop at their own expense as we provide the needed exploration
information in a useful form with pricing based on a percentage of our costs
for originating the information. Further licenses for these same reports are
sold or resold for varying prices based on market demand.

         In conjunction with these services, we generate commission and
service revenue related to the compilation, interpretation, imaging and
marketing of geoscientific data. These services typically involve fees for
performance arrangements with customers who own or desire to obtain mineral
rights and are seeking to determine viability for drilling programs. We seek
to compete in this area by exploiting our upstream relationships, data
sources, and experience in emerging areas such as Africa, South America and
Eurasia. Revenue from geoscientific information and services accounted for
approximately 50% of our revenue in 1998.

OIL AND GAS EXPLORATION AND PRODUCTION OPERATIONS

          We intend to utilize our expertise in the application of
geoscientific technology, as well as our relationships with suppliers and
owners of information and our customers to participate in oil and gas
exploration and production in selected situations which do not conflict with
the business interests of our customers. Through our subsidiary FORTESA, we
are currently pursuing several oil & gas prospects in the U.S. as well as in
West Africa. These prospects are in various stages of development, however
none are actively drilling as of December 1999. The majority of these
investments were accounted for at cost as the Company held a minority
ownership interest in 1998 in the West African opportunity. At December 31,
1998, the Company wrote down a prospect in East Texas by $34,920 due to a
decline in fair market value. The Company's cost basis in all of these oil &
gas positions totaled approximately $171,000. During 1998, two wells in
Kansas began producing with cash distributions expected to begin after the
operator has recovered the drilling costs.

RECENT DEVELOPMENTS

FORTESA ACQUISITION

         Effective March 30, 1999, we purchased all of the outstanding shares
of stock of FORTESA Corporation, a Texas corporation, from the Beall Living
Trust, its sole shareholder, the trustee for which is Rogers E. Beall, our
chairman and chief executive officer, in exchange for 50,000 shares of the
Company's Series A Convertible Preferred Stock plus 8,055 shares of Common
stock. At the time of the acquisition, FORTESA's assets consisted of oil and
gas interests located in East Texas and the Republic of Senegal and were
valued at approximately $171,000, a figure that represents the book value of
the assets to FORTESA.


                                      4
<PAGE>

FORTESA ASSETS

         Mr. Rogers E. Beall, our chairman and chief executive officer formed
FORTESA in May 1997 to pursue an opportunity to develop natural gas reserves
in an onshore block owned by Petrosen, the national oil company of the
Republic of Senegal and referred to as the THIES Block. Such opportunity was
not available to us at the time due to our financial condition. The THIES
Block consists of approximately 998,000 onshore acres adjacent to Dakar, the
Capital of Senegal. In February 1997, Petrosen drilled an exploratory well on
the acreage that was tested successfully in two zones, including a flow of
4.3 million cubic feet per day from one of the intervals, a Campanian sand
interval, at 4,200 feet. The Company estimates that the required expenditures
for the initial development of the THIES Block will be approximately $5.4
million.

         To develop the THIES Block, FORTESA entered into a joint venture in
December 1997 with Benton Oil and Gas Company under which FORTESA retained a
15% working interest in the project. The terms of the joint venture required
Benton to act as the operator of the venture and to commit the first $5.4
million required to develop the interest. FORTESA was required to fund its
share of capital requirements after Benton's committed expenditures were
made. We estimated that the development of the THIES Block will require
drilling two to five additional wells and the construction of a pipeline to
deliver the natural gas produced to the local power generating facility
approximately 42 kilometers from the field. In November 1999 we entered into
a gas sales agreement to sell our future production to this power plant. See
"Recent Developments Concerning Fortesa" below.

         FORTESA also holds a small position in exploration acreage in east
Texas that we believe is prospective for gas exploration. This acreage is
adjacent to known productive areas that have exhibited commercial production
in the 1990's.

RECENT DEVELOPMENTS CONCERNING FORTESA

         On October 23, 1999, our subsidiary FORTESA entered into a new
agreement with Benton Oil and Gas Company (Senegal) Ltd. by which FORTESA has
assumed all obligations and rights of Benton Oil and Gas Company under the
joint venture in the THIES Block. In addition, Benton purchased 135,000
shares of the Company's Series B Convertible Preferred Stock, liquidation
value $10.00, for $750,000 in cash, and in consideration for services
rendered consisting of Benton's prior development expenditures on the THIES
Block. In connection with the issuance of Series B Convertible Preferred
Stock, the Company also granted Benton registration rights for common stock
underlying Benton's shares of preferred stock.

         A condition precedent to this agreement was the granting of a
release from Petrosen to Benton of the latter's obligations under the prior
joint venture agreement. On November 16, 1999, we obtained that release for
Benton from our other partner, PETROSEN. Under this agreement, we also
released Benton on our behalf from Benton's above obligation to spend
$5,400,000 to develop the Gadiaga Field. As a result, we are now obligated to
develop the Gadiaga Field without Benton, and we have assumed the role of
`operator' of this project from Benton, with the consent of PETROSEN.

         Our agreement with Benton requires FORTESA to obtain additional
equity financing of at least $500,000 on terms equivalent to those of the
Series B Convertible Preferred Stock. Upon obtaining a letter of intent to
fund the additional equity, FORTESA was required to issue a purchase order
for pipe to be used in our construction of the pipeline that will transport
gas produced from the Gadiaga Field in the THIES Block. FORTESA issued the
required purchase order for the pipe on November 24, 1999. FORTESA is also
required promptly to commence efforts to obtain additional financing in the
form of a construction loan of up to $1,000,000 to complete installation of
the pipeline. As of the date of this filing FORTESA is engaged in discussions
to secure the required additional equity financing from third-party investors
and the required construction financing from an international bank with
offices in Senegal.

         On November 23, 1999 FORTESA executed a gas sales agreement to
supply natural gas produced from the THIES Block to the main Senegalese power
plant at Cap Des Biches, Senegal. Under the terms of this agreement we have
agreed to dedicate to the main power plant, and the power plant has agreed to
take, all of the natural gas to be produced from the Gadiaga field for at
least two years, at a fixed price. The Company may also sell any production
from the THIES Block, outside of its Gadiaga Field, to the same power plant
or other local energy users and industries.

         We plan to complete construction of the gas delivery pipeline in the
second quarter of 2000, and realize cash flow from gas sales within 90 days
of the first gas transmission. Concurrent with the commencement of this cash
flow, we plan the drilling of two to five additional wells in 2000 and 2001.
In order to satisfy our obligations under the contract with Benton, we must
raise or otherwise promote from new co-venturers the additional funds to
drill at least two wells before February 2001. We plan to use a combination
of cash flow from the production of the first well discussed above, new
capital from private or other sources, project financing or capital from
future co-venturers to fund the additional required wells. We intend to fund
further


                                      5
<PAGE>

development of the Gadiaga gas field, as well as other exploration on the
THIES Block, in the same manner. We have no assurance that we will be able to
successfully obtain this financing on terms acceptable to us, complete the
project and realize continuing revenues from the gas supply contracts.

TERMS OF THE SERIES A CONVERTIBLE PREFERRED STOCK

         The terms of the Series A Convertible Preferred Stock provide for
dividends at a rate of 6% of the liquidation value per annum which will
accrue and accumulate beginning March 31, 2001. We may not pay dividends on
our common stock unless and until all accrued and unpaid dividends on the
Series A Convertible Preferred Stock are paid. Shares of the Series A
Convertible Preferred Stock are convertible into shares of common stock at
the holders' option after March 31, 2001 at a conversion ratio that varies
proportionally with an increase in value of the assets of FORTESA. Initially
the Series A Convertible Preferred Stock will be convertible at a ratio of 10
shares of Common stock for each share of Series A Convertible Preferred
Stock. On each of December 31, 2001, 2002 and 2003, the conversion ratio
shall be adjusted in proportion to the increase in value of the assets of
FORTESA, if any, as determined by an annual PV10 valuation of the assets
performed by an independent engineer. In any event, the conversion ratio
shall not exceed a maximum of 40 shares of common stock for each share of
Series A Convertible Preferred Stock. The maximum ratio would correspond to
an increase in value for the FORTESA assets acquired on March 30, 1999 to
$2,925,000 as determined by the independent valuation.

TERMS OF THE SERIES B CONVERTIBLE PREFERRED STOCK

         The terms of the Series B Convertible Preferred Stock entitle the
holder(s) at any time to convert each share into 10 shares of Common stock at
their option. In addition, we have the right to redeem all or part of the
outstanding shares of Series B Convertible Preferred Stock at the $10.00 per
share liquidation value. If the shares are redeemed prior to three years from
the date of issuance, we must also pay a premium equal to 6% of the
liquidation value per annum from the date of issuance until the date of such
redemption.

EXCHANGE OF COMMON STOCK FOR 12% SENIOR NOTES

         In October 1997, we entered into agreements with the current holders
of all of the Company's 12% Senior Notes due December 31, 1996 which modified
the terms of these Senior Notes. Prior to entering into these individual loan
modification agreements, we had been in non-compliance with various
provisions including payment of interest on these Senior Notes since
September 30, 1993. The provisions of the loan modification agreements
reduced the balance due on the Senior Notes to the outstanding principal
amount only and forgave unpaid interest and suspended other remedies
available to the Note holders. These modification agreements required us to
retire these Senior Notes prior to September 30, 1999. In March of 1999, we
were able to satisfy the balance of our obligations that were not already
paid in cash under the terms of the modification agreement by issuing
1,241,596 shares of common stock, valued at two times the book value of the
Company, in exchange for most of the outstanding Senior Notes. We paid the
remaining outstanding principal balance on the Senior Notes as of September
1999.

EXCHANGE OF COMMON STOCK FOR 6% NOTES, AND WARRANTS TRANSACTIONS

         In March 1999 we issued 977,508 shares of common stock, together
with new warrants to purchase an aggregate 475,000 additional shares of
common stock at a price of $0.30 per share, in exchange for all of our
outstanding 6% Secured Promissory Notes. These 6% Notes had an original
principal amount of $500,000, with an outstanding principal balance of
$411,178 plus accrued interest as of March 29, 1999. In connection with this
transaction, the Noteholders, who were also the warrant holders, agreed to
exercise at least 80% of the outstanding $0.50 warrants, thereby purchasing
shares of new common stock for cash. As an inducement, we offered 150% of the
number of shares of common stock called for by the warrants as originally
issued in 1993 for each warrant exercised. As of October 1999 all of the
Noteholders accepted the offer to exchange their Note for common stock. Of
these converting Noteholders, 92.5% also purchased an aggregate 712,500
shares of common stock for $237,500 in cash. One holder of 25,000 warrants
issued in 1993 at a strike price of $0.50 chose not to exercise his warrants
early. Those 25,000 warrants expire in June 2000.

CUSTOMERS

         We market our geoscientific products and services to major and
independent oil and gas companies. During 1998, 35% of revenues were
attributable to three customers, each of which individually accounted for
over 10% of our revenues. During 1997 and 1996 no one customer accounted for
as much as 10% of our revenues. Although we believe that revenues from our
seismic and geoscientific data library operations will maintain a minimum
level of activity sufficient to sustain that effort, we believe any future
revenue growth is limited to our oil and gas exploration and promotion
activities. We also believe that these activities will require more
co-venturing and partnering with our historical customers and others with
whom we have relationships, than do those of our geoscientific information
business

COMPETITION

         The sale of seismic data and geoscientific analysis, information and
reports is highly competitive in the United States and Western Europe where
we earn most of our revenues. We rely on supplier and owner relationships to
obtain information, data, analysis, and previously compiled studies to market
to our customer base. Our relationships and supplier contracts are with major
and independent oil and gas companies, national oil companies in the U.S. and
Europe, independent geological and geophysical data compilers that own
proprietary equipment, processes, and technologies, and technical institutes
and agencies that employ scientists to advance such research. Due to our
supplier and owner relationships, we are able to leverage expertise from our
suppliers and realize significant efficiencies in data gathering, processing
and analysis activities. We have successfully built these relationships in
key areas of Western Europe, the Caspian Sea, West Africa, and South America.
In addition, we use our proprietary data library of geotechnical reports and
seismic data to provide information cost-effectively to our customer base
compared to similar alternative products offered by our competitors.

         There are a number of other independent oil service companies and
numerous oil and gas companies that create and market seismic data, create
research studies and maintain their own seismic data libraries. Many of our
competitors have longer operating histories, greater financial resources and
larger sales volumes than we have. In 1998, there were approximately ten
companies with operations similar to our operations. Additionally, over one
hundred service companies create new information for sale to the upstream oil
industry in competition with us worldwide. We consider all of these entities
to be significant competitors.

         In the oil and gas exploration and production business there are
many companies competing for the acquisition of mineral properties. Many of
these competitors are better capitalized than we are. We seek to compete in
the exploration for and development of natural gas and crude oil reserves on
the basis of our contacts, relationships, understanding of the application
and use of geoscientific technology and information in the location and
extraction of commercially producible hydrocarbons, and our expertise in
geoscientific disciplines. No assurances can be made that we will have the
resources necessary to fully develop the properties that we currently own or
to acquire new properties for development.

SEASONALITY AND TIMING FACTORS

         Our results of operations can fluctuate from quarter to quarter. The
fluctuations are caused by a number of factors.

         Our seismic licensing, brokering, geotechnical publishing and
service activities are significantly influenced by oil and gas industry
capital expenditure budgets and spending patterns. The timing of oil and gas
industry capital expenditures can be irregular, since spending patterns are
affected by individual oil and gas company requirements as well as
industry-wide conditions. As a result, our geoscientific data licensing
revenue does not necessarily flow evenly or progressively on a sequential
quarterly basis during the year.

         No revenues have been realized from our Oil and Gas activities as of
December 31, 1998. We may bring wells on-line in the future that may cause
significant fluctuations in our financial results. Our future oil and gas
exploration and production operations may be impacted by certain
weather-related events as well as by mechanical and equipment problems or
shortages and other factors, which may delay the hookup of successfully
completed wells and delay the resultant production revenue. Also, due to the
seasonal variations in oil and gas prices, our results from future oil and
gas operations may be subject to significant fluctuations due to variations
in commodity prices.

EMPLOYEES

         As of December 31, 1998 in all of our operations we had 16 full-time
employees and several employees who devote part of their time to our business
who are also officers of other affiliated corporations. Of these full-time
employees, 7 work in geoscientific information, 7 in corporate staff or
administrative operations, and 2 in oil and gas operations. None of our
employees are covered under collective bargaining agreements, and we believe
we have a favorable relationship with our employees. We have employment
contracts with our chief executive officer who also acts as the president of
our FIRST EXCHANGE subsidiary, and also with the president of FORTESA, our
oil and gas subsidiary.

RISK FACTORS AND INFORMATION REGARDING FORWARD LOOKING STATEMENTS

ANY INVESTMENT IN OUR SECURITIES INVOLVES RISK. INVESTORS SHOULD CAREFULLY
CONSIDER, IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS REPORT,
RISKS SUCH AS THOSE DESCRIBED BELOW BEFORE MAKING ANY INVESTMENT DECISION.

         This Annual Report on Form 10-K includes forward-looking statements
and assumptions we have made within the meaning of Section 27A of the
Securities Act of 1933 and Section 21 E of the Securities Exchange Act of
1934. These statements relate to future events or our future financial
performance and involve known and unknown risks, uncertainties and other
factors that may cause our or our industry's actual results, levels of
activity, performance or achievements to be materially different from any
future results, levels of activity, performance or achievements expressed or
implied by the forward-looking statements. In some cases, you can identify
forward-looking statements by terminology such as "may," "will," "should,"
"expects," "plans," "anticipates," "believes," "estimates," "predicts,"
"potential," or other comparable terminology. Although we believe that our
expectations are based on reasonable assumptions, we can give no assurance
when or if our goals will be achieved. Important factors that could cause
actual results to differ materially from those in the forward looking
statements we have made in this report include at a minimum changes in the
exploration budgets of our customers for seismic data, geoscientific studies
and related services. Some additional factors will be actual customer demand
for our seismic data, geoscientific studies and related services, the extent
of our success in acquiring oil and gas properties and in discovering,
developing and producing reserves, the timing and extent of changes in
commodity prices for natural gas, crude oil and condensate and natural gas
liquids and conditions in the capital and equity markets during the periods
covered by the forward looking statements. These are all factors that will be
experienced in the future that we have based our estimates and plans on, and
they may vary significantly from the present and cause us not to realize our
plans in the future.

DECREASES IN ENERGY INDUSTRY SPENDING COULD ADVERSELY AFFECT OUR BUSINESS

         Overall demand for 2D seismic data, geoscientific information, and
the type of related services that we provide depends primarily upon the level
of spending by oil and gas companies for exploration, production and
development activities. Industry spending levels may follow increases and
decreases in the commodity prices for oil and gas, so that demand for our
products and services may be affected to some degree by market prices for
natural gas and crude oil. These prices have historically been very volatile
due to the sensitivity of product prices to market demand. As a result of the
very significant weaknesses in oil and gas commodity prices starting in
mid-1998 and through mid-1999, the level of overall oil and gas industry
exploration activity had declined from levels experienced in recent years.
This has resulted in a significant consolidation in the number of major
customers for our geoscientific products. Our customers' capital spending
decreased significantly in the period immediately after the 1998 annual
report contained herein, due to these recent industry trends. This resulted
in a significant adverse effect in 1999 upon the demand for our services and
our resulting level of operations and cash flow. In addition, potential
revenues to be generated in the future by our oil and gas exploration and
development business may fluctuate with increases and decreases in the market
prices of oil and gas. Many factors beyond our control may affect such oil
and gas operations. These factors include financing activities, the level of
worldwide supply of natural gas and oil, the availability of adequate
pipeline and other transportation and processing facilities and the marketing
of competitive fuels, and similar worldwide factors.

DATA LIBRARY INVESTMENT AND FUTURE LICENSING

         Our method of selling use-licenses for our data library allows us to
sell the same information to multiple buyers. However, data that we have
developed and invested in may not continue to be of interest to customers in
the future due to changes in areas of interest, licensing of the underlying
lands for hydrocarbon exploration by companies, product pricing factors,
political risk changes and perceptions, and changes in financial and other
conditions that can reduce the viability of hydrocarbon extraction in areas
for which we own data. In such cases, we may not fully recover our costs in
acquiring and developing geophysical and other geoscientific data through
future licenses of that data. As a result, we would have to expense costs of
that data library asset without having corresponding revenues, thereby
causing a loss in those periods affected.

AMORTIZATION OF OUR DATA LIBRARY

         Our methods for accounting for investment in our data library can
have a significant effect on the results of our operations for any given
period of time. We amortize our data library based in part on our estimates
of future sales of licenses to our data or over a regular minimum period,
whichever is greater. Estimates are inherently imprecise and may vary from
period to period depending on market developments and our expectations. If we
see that the values in our data library are not being recovered through
revenues at any point in time, we may increase the amortization rates. This
may result in impairments of our data library assets in periods of low
exploration industry interest, and such impairments can have a significant
effect on our reported results of operations.

GOVERNMENT REGULATIONS

         Our operations are affected by a variety of laws and regulations,
including laws relating to the use of information, the environment, taxes,
exports and imports, safety, permitting operations, and investment in certain
countries that may become out of favor with the U.S. or other governments. We
invest in financial and management resources in order to comply with such
regulations and laws, but we cannot always anticipate changes in the laws and
politics, and errors in compliance by operatives of our company. Such
modifications and non-compliance can cause us to lose our investment or
become liable for errors in judgment or actions that will result in losses.

INTERNATIONAL EXPOSURE AND RISKS

         As we increase our investment in countries outside of the U.S., we
increase our exposure to risks that we cannot always anticipate or control by
the rule of law or compliance with standards normal for our business. In the
future, we believe that an increasing amount of our revenue will come from
sales of information and natural resources originating in Senegal and other
countries outside of the U.S., and these revenues will be subject to risks
that are inherent in doing business abroad. These risks include the
possibilities of expropriation of our assets and investments, changes in tax
and other laws, currency exchange rate fluctuations and devaluations, labor
and political disturbances, insurrection or war, disruptions or delays of
licensing, permitting, or leasing activities, and the requirements of partial
local ownership of our operations.

INSURANCE LIMITATIONS

         We attempt to insure against normal liabilities, and to protect our
assets and investments against losses. However, we cannot always obtain
insurance for our operating risks. In addition, sometimes insurance is not
available at cost-effective rates. We will periodically review the insurance
coverage we have in effect, and try to insure against possible losses when
coverage is available at rates that do not make our projects non-commercial.

DRILLING HAZARDS AND DRY HOLES COULD AFFECT OUR OIL AND GAS ACTIVITIES

         Our oil and gas operations will be subject to hazards incident to
the drilling of oil and gas wells, such as cratering, explosions,
uncontrollable flows of oil, gas or well fluids, fires, pollution, or other
environmental risks, as well as to the risk that we may not encounter
commercially productive natural gas or oil reserves. Some of these hazards
can cause personal injury and loss of life, severe damage to and destruction
of property and equipment, environmental damage and suspension of operations.
However, since we sometimes may not act as operator in our oil and gas
drilling business, these factors may be dependent upon our petroleum company
co-venturers to conduct operations in a manner so as to minimize these
operating risks. In accordance with industry practice, we will maintain
insurance against some, but not all, of these operating risks. There can be
no assurance that adequate insurance will be available in the future, or that
we will be able to maintain adequate insurance on terms and conditions
acceptable to management. As a result of the risks inherent in oil and gas
operations, the success of our oil and gas exploration, development and
production activities is uncertain.

LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS

          Our operations are dependent upon a relatively small group of
management and technical personnel. The loss of one or more of these
individuals could have a material adverse effect on our operations and future
results. Equity ownership and other incentives are offered to attract and
retain our key employees. In addition, we have employment agreements with our
chairman and chief executive officer, Rogers E. Beall, who also acts as the
President of our FIRST EXCHANGE subsidiary, and also with FORTESA president,
Hayne S. Blakely.

OUR ABILITY TO OBTAIN ADDITIONAL FINANCING COULD IMPAIR OUR FUTURE OIL AND
GAS ACTIVITIES

         The success of our oil and gas development activities depends
substantially on our ability to obtain additional financing. In particular,
our activities in Senegal require us to make significant capital expenditures
to continue the development of that project, which will depend upon our
ability to obtain additional financing. See "Oil and Gas Exploration and
Production Operations - Recent Developments." Although discussions with
potential equity and debt investors and lenders are ongoing, we have no firm
commitments for such additional financing, and no assurances can be made that
additional financing will be obtained.

REGIONAL EVENTS MAY AFFECT OUR GEOGRAPHICALLY CONCENTRATED OPERATIONS

         Most of the seismic data in our library is 2D data covering lands
located in the Rocky Mountains, Michigan Basin and other onshore areas of the
U.S. The majority of our compiled geoscientific data and studies cover areas
in the Caspian Sea, South America and western Africa. Our interests in oil &
gas properties are concentrated in east Texas and The Republic of Senegal in
western Africa. Any regional events that increase costs, reduce availability
of equipment or supplies, reduce demand or limit production will impact us
adversely in these specific areas.

EXTENSIVE GOVERNMENTAL REGULATION

         The oil and gas industry in general is subject to extensive
governmental regulation, which changes from time to time in response to
economic or political conditions. In particular, oil and gas exploration and
production are subject to international and U.S. federal and state
regulations governing environmental quality and pollution control, state
limits on allowable rates of production by well or peroration unit, and other
similar regulations. These regulations generally are intended to prevent
waste of natural gas and oil, protect rights to produce natural gas and oil
between owners in a common reservoir and control the amount of natural gas
and oil produced in order to avoid waste and reservoir damage, by assigning
allowable rates of production and control contamination of the environment.
Environmental regulations will affect our operations on a daily basis. Also,
we believe that the trend toward more expansive and stricter environmental
laws and regulations will continue. At present, we do not yet expend material
amounts to comply with such regulations. The implementation of new, or
changing of existing laws or regulations affecting the oil and gas industry
could have a material adverse impact on us in the future.

ITEM 2.  PROPERTIES

         We lease office space under non-cancelable operating leases. Our
lease for our corporate and operating offices in Houston, Texas amounts to
7,650 square feet and expires in January 2001. Our lease for our U.K.
operations amounts to 1,565 square feet for our facilities just south of
London, England, and expires in June 2000. Our offices in Baku, Azerbaijan
are in the facilities of one of our publication co-venturers and the space is
made available to us at no charge.

         We hold rights to a natural gas discovery known as the Gadiaga Field
that is located in the THIES Block in the Republic of Senegal through our
wholly owned FORTESA subsidiary. Proven reserves from the initial well in the
THIES Block are approximately 2BCF of natural gas. In order to exploit our
rights under the agreement with Petrosen, we are obligated to make
expenditures in the amount of $5,400,000 to fund the construction of a
delivery pipeline and the drilling of two development wells in the Gadiaga
gas field. See "Liquidity and Capital Resources" and "Oil and Gas Exploration
and Production Operations - Recent Developments".

         We also hold various mineral lease rights on certain speculative oil
& gas acreage located in east Texas. Expenditures made to secure these rights
are recorded at cost in the accompanying financial statements. We
periodically evaluate the expected future value of these rights in order to
determine if they have become impaired or reduced in value. As of December
1998 the value of these rights was approximately $171,000. (See Note 1
- - - Summary of Accounting Policies, Oil & Gas Properties in the accompanying
financial statements)

ITEM 3.  LEGAL PROCEEDINGS

         We are a defendant in a lawsuit filed on October 28, 1997 in the
U.S. District Court for the Northern District of Oklahoma, brought by two
parties claiming to be the successors-in-interest to McKenzie Management
Inc., a minority owner of 1,200 miles of 2-D seismic data acquired by us in
September 1990 from McMoran Oil & Gas Company and Adobe Resources
Corporation. A portion of this data was originally owned by a joint venture
comprised of McMoran, Adobe and McKenzie Management Inc. At the time of our
original purchase of this data, McMoran and Adobe could not locate McKenzie
and indemnified us "against any and all future claims, costs, expenses or
causes of action that may be asserted by the referenced minority owner...."
In June 1994, we sold our interest in this data to Seitel Corporation and
indemnified Seitel against claims relating to the seismic data being sold.
The plaintiffs seek approximately $600,000 to $1,500,000, plus punitive
damages and attorney's fees. We believe we are indemnified against loss based
on our purchase contract with McMoran and Adobe. This lawsuit is still in the
early stages of discovery and we cannot predict the extent of our liability,
if any. No specific provision has been recorded in the accompanying financial
statements for any loss that may be realized from this matter.

         This Annual Report on Form 10-K represents the first filing we have
submitted to the Securities and Exchange Commission since our filing on Form
10-Q for the period ended September 30, 1992. See "Fortesa Acquisition" above
for description of the Company's Convertible Preferred Stock series A and B
that was issued during 1999.

         To our knowledge as of November 30, 1999 there are approximately 600
holders of record of our Common stock.

DIVIDEND POLICY

         We have not paid cash dividends since 1990, and we intend to retain
future earnings from the next several years to provide funds for use in the
expansion of our business. We do not intend to pay dividends in the
foreseeable future.

RECENT SALES OF UNREGISTERED SECURITIES

         In December 1996 the President of the Company purchased 253,790
shares common stock at $.02 per share. The issuance of such shares was exempt
from registration under Section 4(2) of the Securities and Exchange Act of
1933.

         On January 1, 1997, the Company issued 150,000 shares of its common
stock at par value to its Executive Vice President in exchange for all of the
shares of Blackwell Supply, Inc. Through Blackwell, the Company conducts its
domestic geophysical information activity, including the marketing and sale
of airborne remote sensing surveys. The issuance of such shares was exempt
from registration under Section 4(2) of the Securities and Exchange Act of
1933.

         Effective March 30, 1999, we issued 50,000 shares of our Series A
Preferred Stock and 8,055 shares of our common stock in exchange for all of
the common stock of Fortesa. Shares of our Series A Preferred Stock are
convertible to shares of common stock at an initial ratio of 10 shares of
common stock for each share of Series A Preferred Stock. The conversion ratio
is adjustable in proportion to an increase in value for the FORTESA assets
acquired on March 30, 1999. In any event the conversion ratio shall not
exceed a maximum of 40 shares of common stock for each share of Series A
Convertible Preferred Stock. The issuance of such shares was exempt from
registration under Section 4(2) of the Securities and Exchange Act of 1933.

         In March 1999 we issued 977,508 shares of common stock, together
with new warrants to purchase an aggregate 475,000 additional shares of
common stock at a price of $0.30 per share, in exchange for all of our
outstanding 6% Secured Promissory Notes. The issuance of such shares and
warrants was exempt from registration under Section 3(a)(9) of the Securities
and Exchange Act of 1933.

         In March of 1999, we issued 1,241,596 shares of common stock, valued
at two times the book value of the Company, in exchange for outstanding 12%
Senior Notes. The issuance of such shares was exempt from registration under
Section 3(a)(9) of the Securities and Exchange Act of 1933.

         As part of our transaction with Benton, we issued 135,000 shares of
the Company's Series B Convertible Preferred Stock, liquidation value $10.00,
for $750,000 in cash and in consideration for the prior expenditures of
Benton to develop our interest in the Senegal gas prospect. Each share of
Series B Convertible Preferred Stock is convertible into 10 shares of common
stock. The issuance of such shares was exempt from registration under Section
4(2) of the Securities and Exchange Act of 1933. See "Recent
Developments - RECENT DEVELOPMENTS CONCERNING FORTESA" in Item 1 for a
discussion of this transaction.

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

RESULTS OF OPERATIONS

SALES OF SEISMIC AND GEOSCIENTIFIC DATA

       Total revenue for the year ended December 31, 1998 increased
approximately $594,000 or 25% compared to the same period in 1997. Revenues
by category fluctuated but the primary net increase was due to increased
licensing and brokerage of geoscientific products related to the Caspian Sea
region. Declines in revenue from our commission income are primarily
attributable to a decrease in oil and gas exploration activity in East Texas
and a resultant decrease in demand for our domestic sales of geophysical
information. We also experienced a decline in net revenue interest payments
accruing to us from the sale of seismic data, in which we have an expiring
interest, by third parties. Revenues for the year ended December 31, 1997
were up over 1996 by approximately $139,000 or 6%, as a result of
international promotion successes in 1997 in West Africa, and increases
realized in our Caspian Sea geologic products.

OIL AND GAS

         Our investments in oil & gas properties have produced no operational
revenue as of this filing. The natural gas reserves held by our subsidiary
FORTESA are not yet producing. Revenue associated with these reserves is
subject to certain capital expenditures for which we are obligated and which
have yet to be made. See "- Liquidity and Capital Resources" for a discussion
of these capital expenditure requirements.

COST OF SALES

         Cost of sales is composed of employee and administrative costs directly
associated with specific projects or sales, and of partner and data owner
payments for licensed and brokered data. These costs do not include the
amortization of the associated data library that is included in Expenses after
Gross Margin. Costs of sales have regularly averaged approximately 50% of
revenues during the period covered herein, in spite of product mix fluctuations.


CORPORATE AND OTHER

         Selling and General and Administrative expenses increased
approximately 12% or $110,000 for the year ended December 31, 1998 as
compared to year ended December 31, 1997 primarily as the result of increased
accounting costs associated with our efforts to comply with public company
reporting requirements and increased bad debt expense. Such expenses did not
materially change during fiscal years 1996 and 1997.

         Depreciation and amortization expense, which consists primarily of
amortization of our data libraries, increased approximately 50% or $152,000
for the year ended December 31, 1998 as compared to the year ended December
31, 1997. This was due to the increased level of capital expenditures for new
geoscientific reports in the Caspian Sea region that were completed and
placed on the market during 1998. These reports are normally amortized over
approximately three years. Depreciation and amortization expense for the year
ended December 31, 1997 decreased approximately 60% compared to the 1996
period such decrease was due to a final regular amortization of our 2D
seismic library to its residual carrying value made in 1996. Subsequent to
December 31, 1996, amortization charges to the 2D library were made on only
the residual value of the seismic library, which represents a 10% residual on
the original cost, over a 15 year period which resulted in significantly
lower amortization charges than were previously made.

         During the three years ended December 31, 1998, we recognized gains
totaling approximately $1.4 million in connection with settlements and
statutory extinguishments of debt with certain trade creditors. These
non-cash gains occurred in connection with the decline of our 2D seismic
brokerage activities and were substantially offset by the associated
product-line final regular amortization costs of the 2D data library. These
costs were shown as operating costs. These final settlements and
extinguishments are shown as extraordinary items in the accompanying
financial statements. We do not believe significant gains or compromised
amounts of this nature are likely to be realized in the future, as these
amounts resulted from the substantial elimination of our operations in the
domestic seismic brokerage business by the end of 1993.


                                      15
<PAGE>

         Interest expense increased in each of the last three years in
connection with the 6% Notes until they were converted into common stock and
warrants in March 1999. After 1993, due to the uncertainty of our ability to
pay amounts due until they were converted into common stock and warrants in
March 1999 for interest on our outstanding debt, interest was not accrued
ratably on any of our debt obligations, except for interest that was actually
paid. See Note 10 - Subsequent Events in the accompanying financial
statements.

LIQUIDITY AND CAPITAL RESOURCES

         Our cash flow from operations was $1,106,439, $540,742 and $347,181
for each of the three years ended 1998, 1997 and 1996 respectively. A line of
credit with our bank for $100,000 is secured by our Accounts Receivable, and
has an available amount of $100,000 as of December 31, 1999. Our president
had personally guaranteed this line of credit, pending completion of our
restructuring.

         We had a working capital deficit at December 31, 1998 of
approximately $670,000. Of this, we expect to be able to settle liabilities
included in the current section of the accompanying balance sheet in the
amount of approximately $200,000 from non-cash transactions in the form of
services or trades of information.

         Expenditures on acquisition of data for resale were approximately
$765,000 and $81,000 in 1998 and 1997 respectively. We expect to fund capital
expenditures in the next 12 months through customer pre-commitments to any
approved new projects, prior to capital expenditures exceeding $25,000 on any
single project.

         We believe that cash flows from operations will be sufficient to
fund our working capital needs for the next 12 months, except for required
expenditures in conjunction with Oil and Gas development in the Republic of
Senegal, which will require additional financing.

         See "FORTESA Acquisition" and "Recent Developments" in ITEM 1 for
possible future impacts to Liquidity and Capital Resources.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." The
Statement establishes accounting and reporting standards requiring that every
derivative instrument (including certain derivative instruments embedded in
other contracts) be recorded in the balance sheet as either an asset or
liability measured at its fair value. The Statement requires that changes in
the derivative's fair value be recognized currently in earnings unless
specific hedge accounting criteria are met. Special accounting for qualifying
hedges allows a derivative's gains and losses to offset related results on
the hedged item in the income statement, and requires that a company must
formally document, designate, and assess the effectiveness of transactions
that receive hedge accounting. Statement 133 is effective for fiscal years
beginning after June 15, 1999 and cannot be applied retroactively. Statement
133 must be applied to (a) derivative instruments and (b) certain derivative
instruments embedded in hybrid contracts that were issued, acquired, or
substantively modified after December 31, 1997 (and, at our election, before
January 1 1998). We have not, and we are not engaging in hedging activities,
and we do not buy or sell derivative instruments. Therefore we do not believe
that application of this recent statement will have any effect on our
consolidated financial statements.


                                      16

YEAR 2000

         Many currently installed computer systems and software products are
coded to accept only two-digit entries in the date code field. Beginning in
the year 2000, these date code fields will need to accept four-digit entries
to distinguish 21st century dates from 20th century dates. As a result,
computer systems and software used by many companies may need to be upgraded
to comply with such "Year 2000" requirements. Significant uncertainty exists
concerning the potential effects associated with such compliance, but systems
that do not properly recognize such information could generate erroneous data
or cause a system to fail.

         Compliance Program.  In order to address the Year 2000 issue, our
information technology manager reviewed key automated systems and related
processors to assess if they would remain functional through the year 2000.
We have concluded that the software and systems utilized in our operations
are compliant regarding Year 2000 issues. All of the software and systems
utilized are of the "off the shelf" variety and the various vendors have
supplied certifications to us to the effect that their software will not be
subject to problems related to the date change.

         Our State of Readiness.  A review and assessment of the information
technology and non-information technology systems was completed as of October
29, 1999 and did not identify any systems which are not Year 2000 compliant.
Due to the non-automated nature of our relationships with both our suppliers
and customers we believe that our operations will not be significantly
disrupted, even if third parties with whom we have relationships are not Year
2000 compliant. In the event that our customers are not Year 2000 compliant,
their businesses could be affected such that they might not order our
products during periods of their internal correction methods

         Costs to Address Year 2000 Compliance Issues.  We believe that we
will not be required to make any material expenditure to address the Year
2000 problem as it relates to our existing systems. To date, costs incurred
to address Year 2000 compliance have been related to or licensing updated
software systems for our internal computers, the costs of which have not been
material. We have charged to income those upgrading costs as we incurred
them. These costs have been funded from cash provided by operating activities.

         Risk of Non-Compliance and Contingency Plan.  The goal of the Year
2000 project has been to ensure that all of the critical systems and
processes, which are under our direct control, remain functional. However,
because certain systems and processes may be interrelated with systems
outside of our control, there can be no assurance that all of our
implementations have been successful. There can be no assurance that
unexpected Year 2000 compliance problems from either the Company or our
vendors, customers and service providers would not materially and adversely
affect our business, financial condition or operating results. We will
continue throughout 1999 to consider the likelihood of a material business
interruption due to the Year 2000 issue.

IMPACT OF INFLATION AND CHANGING PRICES

         The general levels of exploration activity in the oil and gas
industry directly affect the cost of acquiring, processing and reselling
geoscientific data and exploration and development costs of advancing our gas
projects. The pricing of our products and services, and of the costs we must
pay for hydrocarbon development are primarily a function of these factors.
For these reasons, we do not believe inflationary trends have had any
significant impact on its financial operating results during the three years
ended December 31, 1998. But management believes the large fluctuations in
the worldwide hydrocarbon product pricing during this period, and oil field
services excesses and shortages resulted in cost fluctuations that presented
significant challenges to us for planning the development of the Senegalese
project, and our cash flow management

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Our exposure to market risk, including adverse changes in commodity
prices, interest rates and foreign currency exchange rates is discussed below.

COMMODITY PRICE RISK

         We have not produced revenues as of December 1999 related to sales
of natural gas, crude oil, condensate and natural gas liquids. We have no
program in place to undertake to hedge our position with respect to these
commodities and does not originate or buy derivative type instruments.
However, to initially minimize price fluctuation risk factors of our gas
development project in Senegal, we agreed to a fixed price per MCF in our gas
supply agreement over the next two years with the power plant that is party
to such agreement.

         Fluctuations in hydrocarbon commodity prices could have a material
impact on the level of revenues in future periods.

INTEREST RATE RISK

         We have no variable rate debt, and therefore we have no open
interest `rate swap' or interest rate `lock agreements'.

CURRENCY EXCHANGE RATES

         We conduct some of our business in British `pounds sterling', and in
`CFA' in the Republic of Senegal (the CFA is directly tied monetarily to the
French Franc which will be replaced by the `Euro' in the next year).
Therefore we are subject to foreign currency exchange rate risk on cash flows
related to sales, expenses, financing and investing transactions. Exposure
from market rate fluctuations related to activities in the Republic of
Senegal, where the Company's functional currency is the CFA, and in the
United Kingdom, where the Company's functional currency is British Pounds
Sterling, is not material at this time, but future increases in the strength
of the USA `dollar' could have a negative effect on our revenues from
international information license sales and gas sales transactions.

         The financial statements and financial statement schedules required
by this Item are set forth on pages F1 through F26 hereof and incorporated

COMMITTEES OF THE BOARD

         The board has two standing committees, the identities, memberships
and functions of which are described below.

         AUDIT COMMITTEE.  The members of the Audit Committee of the board are
Edward M. Trapp and Arthur O. Beall. The Audit Committee's functions include
making recommendations concerning the engagement of independent auditors,
reviewing with the independent auditors the plan and results of the auditing
engagement, approving professional services provided by the independent
auditors, and reviewing the adequacy of the Company's internal accounting
controls and reviewing our refinancing plans and strategies.

         COMPENSATION COMMITTEE.  All of the outside directors are members of
the Compensation Committee. They are Edward M. Trapp and Arthur O. Beall. The
Compensation Committee's functions include a general review of the Company's
compensation and benefit plans to ensure that they meet corporate objectives.
The Compensation Committee reviews the Chief Executive Officer's
recommendations on (a) compensation of the senior executive officers of the
Company, (b) granting of awards under the Company's stock option and other
benefit plans and (c) adopting and changing major Company compensation
policies and practices. In addition to reviewing the compensation for the
Chief Executive Officer, the Compensation Committee reports its
recommendations to the whole board for approval.

INFORMATION REGARDING MEETINGS

         The Board and the Audit Committee each held two meetings in 1998.
Compensation Committee issues were also discussed at each board meeting and
all outside directors are members of the Compensation Committee. Each
director attended all of the meetings of the board and of the committees
(if any) on which such person served.

EMPLOYEE STOCK OPTION PLAN

     In July 1990, the Company reserved 500,000 shares of common stock for
issuance under its Employee Stock Option Plan. All Incentive Stock Options
("ISO's") will be granted to employees at an exercise price of not less than
the fair market value of the stock on the date of grant. All Non-incentive
Stock Options ("NSO's") will be granted at an exercise price of not less than
85% of the fair market value of the stock on the date of grant. The Company
and the Board's Compensation Committee, on February 3, 1998, re-assigned the
entire 500,000 options from terminated employees to current employees of the
Company. The strike price was set at $.20 per share. Of the 500,000 shares
granted, the Company's President was granted 300,000 shares or 60% of the
total available shares. Due to the Company's liquidity requirements in August
1998, the President agreed to exercise all of his options, thereby infusing
$60,000 of cash into the Company. The remaining 200,000 options are
outstanding at December 31, 1998.

DIRECTOR STOCK OPTIONS

     In July 1990, we also reserved 150,000 shares of common stock for
issuance under its Directors' Stock Option Plan. All options will be granted
to non-employee directors at an exercise price of not less than the fair
market value on the date of grant. Each year, the directors are granted
options to purchase 10,000 shares of common stock as compensation for their
services.

DIRECTOR COMPENSATION

         In addition to the stock options discussed above, the directors were
paid 10,000 shares of common stock as compensation for their services. The
directors are reimbursed for all out of pocket expenses incurred in attending
any meeting of the board or any committee thereof.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Set forth below is a description of certain transactions entered
into between the Company and certain of its directors, nominees for director
and stockholders.

         During the period 1993 until 1996, the President of the Company had
not received his contracted salary amount in cash compensation due to cash
liquidity problems. The unpaid salary was accrued. In December 1996, the
President entered into an agreement to purchase 253,000 shares of common
stock at $0.02 cash per share and to forego the $253,000 compensation due
him, for a total value increase to the Company of $258,860. The accompanying
financial statements reflect this agreement to forego cash compensation, and
to reflect the issuance of stock.

         In 1993, the President of the Company agreed to act as the general
partner of a limited partnership formed to make investments in oil and gas
exploration, development, reserves, and to make financing investments to
facilitate portions of our business plan that were outside of our financing
capabilities. The 15 owners of this limited partnership consist of our
shareholders and our noteholders. FIRST SEISMIC owns a minority interest in
the limited partnership which was granted in exchange for data use positions
extended by us to the limited partnership. The limited partnership is engaged
in leasing interests in East Texas with natural gas prospects.

         In 1993, the Company sold one license for its East Texas data-set to
the limited partnership, prior to posting that data-set for sale for the
benefit of the Senior Noteholders, for consideration of $16,000 in cash and
$84,000 upon our successful promotion of the East Texas prospect(s) and
receiving reimbursement for seismic data costs from the promoted incoming
partners. We successfully leased the prospect but elected not to promote it
until a 3-D seismic survey could be arranged over the prospect. In 1997,
arranged for a 3-D seismic survey over this acreage that was interpreted in
1998 and indicated only moderate commercial viability. Therefore, the $84,000
contingent receivable is not reflected in the financial statements, and will
be reported as a gain in the year received from LTD, if the Company promotes
this first, or one of the other prospects successfully with seismic costs
reimbursed.

         On January 1, 1997, the Company issued 150,000 shares of its common
stock at par value to its Executive Vice President in exchange for all of the
shares of Blackwell Supply, Inc. Blackwell is used to conduct the domestic
geophysical activity of the Company, including its airborne remote sensing
surveys.

                                      23
<PAGE>

         We entered into a series of transactions in March 1999 with the
holders of our 6% Notes and our 12% Notes. Please refer to the section of
this report entitled "Recent Transactions" for a detailed discussion of these
transactions.

         In March of 1999, we acquired all of the shares of stock of Fortesa
Corporation, a Texas Corporation ("Fortesa"), from its sole shareholder,
Rogers Beall who is our President and CEO. Mr. Beall formed Fortesa in May of
1997 for the purpose of acquiring certain oil and gas interests in the
country of Senegal. Prior to forming Fortesa, Mr. Beall presented this
development opportunity to our board of directors. After considering the
opportunity, we declined to invest in the opportunity due to our financial
position. Subsequent to its formation, Fortesa entered into a joint venture
with Benton Oil, a Delaware corporation, ("Benton") to develop these
interests. In February 1999, Mr. Beall again presented our board the
opportunity to participate in the Senegal joint venture through the purchase
of Fortesa stock. Upon consideration of the prospects of the venture and the
potential return of the investment, the members of the board, other than Mr.
Beall who did not take part in the meeting, voted to acquire all of the
outstanding shares of Fortesa in exchange for 50,000 shares of the Company's
Series A Preferred Stock and 8,055 shares of our Common stock.

Board of Directors and Stockholders
FIRST SEISMIC Corporation and Subsidiaries
Houston, Texas

We have audited the accompanying consolidated balance sheets of FIRST SEISMIC
Corporation and Subsidiaries as of December 31, 1998, 1997, 1996 and 1995,
and the related consolidated statements of operations, changes in
stockholders' equity (deficit) and cash flows for the years then ended. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of FIRST
SEISMIC Corporation and Subsidiaries at December 31, 1998, 1997, 1996 and
1995, and the results of their operations and their cash flows for the years
then ended in conformity with generally accepted accounting principles.

As discussed in Note 1, the Company has a substantial working capital deficit.

                                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 1        SUMMARY OF ACCOUNTING POLICIES

              The reporting entity in these financial statements consists of
              FIRST SEISMIC Corporation ("FIRST"), its three wholly-owned
              subsidiaries: FIRST EXCHANGE Corporation ("FEC"), First Exchange
              Limited ("FEL") and Blackwell Supply, Inc., d.b.a. Blackwell
              Trading, Inc. (BTI) collectively referred to as the Company.
              FIRST, FEC and BTI are incorporated in the State of Delaware. FEL
              is a United Kingdom Corporation. The Company originates, markets,
              and owns domestic geophysical and international geological
              information for licensing to oil and gas exploration companies.
              The Company's customers are primarily located in the United States
              and Western Europe, and its suppliers are primarily major oil
              companies, national government oil companies, or independent
              geo-scientific consulting firms and oil service providers.

              The Company acquired 100% of the stock of its former 75% net
              revenue interest affiliate, Blackwell Supply, Inc., effective
              January 1, 1997 for issuance of stock. (See Note 5)

              The Company went public in September 1990, however the last 10-K
              filed with the SEC was for the period ending December 31, 1991.
              Currently, the Company is not in compliance with SEC requirements
              for filing and reporting. However, the Company intends to become
              current with all SEC requirements as soon as practicable.

              PRINCIPLES OF CONSOLIDATION

              The consolidated financial statements include the accounts of
              FIRST, FEC, BTI and FEL. All material intercompany accounts and
              transactions have been eliminated in consolidation.

              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.

                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 1        SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

              CONCENTRATIONS OF CREDIT RISK

              Financial instruments which potentially subject the Company to
              concentrations of credit risk consist principally of trade
              receivables and cash. The Company places its cash with high credit
              quality financial institutions. Generally, no collateral or other
              security is required to support customer receivables. To reduce
              credit risk, a customer's credit history is reviewed before
              extending credit. In addition, an allowance for doubtful accounts
              is established as needed based upon factors surrounding the credit
              risk of specific customers, historical trends, and other
              information. Management has established an allowance for doubtful
              accounts at December 31, 1998 in the amount of $124,481. There was
              no allowance as of December 31, 1997, 1996 and 1995. During 1998,
              35% of revenues were attributable to three customers.

              CASH

              The Company has an interest bearing account primarily dedicated
              for payments to the 12% Senior Noteholders. In addition to other
              uses, the Company has used this account to deposit funds earned by
              the Company from the sale of certain licenses of Company owned
              data or revenue interest payments, pending disbursements to the
              Senior Noteholders. Payments to these Noteholders have been
              periodically made when sufficient levels of cash have accumulated
              to justify disbursement. Cash pledged for payment to the Senior
              Noteholders held in this account at December 31, 1998, 1997, 1996
              and 1995 was $11,786, $93,357, $27,024 and $50,143, respectively.
              The amounts were subsequently disbursed by the Company pro rata to
              each of the 12% Senior Noteholders.

              Cash and cash equivalents consist of demand deposits and money
              market funds and other unrestricted liquid investments held at
              depository institutions with maturity of three months or less.

              DATA LIBRARY

              The costs included in Data Library represent company owned seismic
              data, net revenue interests in seismic data previously owned and
              sold to third parties, and geo-scientific reports. The Company
              capitalizes third party costs plus internal direct costs loaded
              with overhead relating to the acquisition of the Data Library.
              Amortization of these costs commences as soon as a new project is
              completed.

                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 1        SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

              Seismic costs are amortized over the greater of the estimated
              volume of anticipated revenues that the Company expects to realize
              from the licensing of its Company owned seismic data or a five
              year period with a (10%) ten percent residual value using the 150%
              declining balance method. In 1992, the Company's investment in its
              data library had a residual value of $2,653,290. Beginning in
              1992, the Company elected to amortize the residual balances on a
              straight-line basis over a fifteen-year period. The residual value
              amortization amounted to $176,886 for each of the years ending
              December 31, 1998, 1997, 1996, and 1995.

              Net revenue interest in seismic data previously owned and sold to
              third parties is amortized over a five-year period with no
              residual value using the 150% declining balance method.

              The Company's ownership interest in geo-scientific reports is
              amortized over three years to a ten-percent residual value. The
              amortization during the three-year period is the greater of 4.5%
              per sale up to 20 licenses or 2.5% per month cumulative minimum.
              The residual value is then amortized over 15 years on a
              straight-line basis.

              DATA AND AGENCY POSITIONS

              Data and agency positions include Seismic Data Rights and agency
              agreements with certain foreign governments. The Company
              capitalizes third party costs plus an allocation of internal
              overhead costs relating to the acquisition of data and agency
              positions.

              Data Use Rights represent the value of data that the Company has
              to use or has to give to others regarding the license of seismic
              data relative to third parties. Such rights were obtained or are
              owned primarily by trade of the use of seismic data or of services
              provided by the Company.

              Agency agreements represent the Company's costs of organizing
              third parties' data and opportunities into marketable products or
              promotion for fees to energy companies on a multi client basis.
              Such costs are amortized over five years, or written off if the
              Company concludes the relationship has no future earning value.

              PROPERTY AND EQUIPMENT

              Property and equipment are recorded at cost. Depreciation of
              property and equipment is provided using accelerated methods over
              the estimated useful lives of three to five years.

NOTE 1        SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

              INVESTMENT IN OIL AND GAS PROSPECTS

              In 1993, the Company initiated efforts and agreements to earn
              interests in oil and gas reserves in both the domestic and the
              international arena by organizing and promoting acreage and
              opportunities, and by using its information to obtain rights for
              hydrocarbon reserve ownership. As of 1997, the Company has
              positions in East Texas (See Note 5), Kansas, and Guinea-Bissau,
              West Africa. The necessary investment to advance these positions
              had either been raised from third parties, thus carrying the
              Company on a portion of the exploration results, or the acreage
              has been analyzed and leased for exploration rights which include
              the Company. The Company owns the "right of first refusal' to
              acquire a similar and more presently significant interest in
              Senegal, West Africa (See Note 10).

              These investments are accounted for at cost as the Company holds a
              minor ownership interest. At December 31, 1998, the Company wrote
              down one prospect by $34,920 due to a decline in fair value. The
              Company's cost basis in these investments totaled approximately
              $170,710. During 1998, two wells in Kansas began producing with
              cash distributions expected to begin after drilling costs are
              paid.

              INCOME TAXES

              The Company uses the balance sheet approach for recording deferred
              taxes. The balance sheet approach accounts for deferred income
              taxes by applying statutory tax rates in effect at the balance
              sheet date to differences between the book basis and the tax basis
              of assets and liabilities. The resulting deferred tax assets and
              liabilities are adjusted to reflect changes in tax law or rates.

              The Company and its wholly owned U.S. subsidiaries file a
              consolidated federal income tax return.

              OPERATIONS

              As shown in the accompanying financial statements, the Company had
              losses before settlements/liability extinguishments of $65,756,
              $18,292, $537,557 and $991,424 in 1998, 1997, 1996 and 1995,
              respectively. As of December 31, 1998, current liabilities
              exceeded current assets by $669,061.

                                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 1        SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

              The Company's trade payables are reviewed periodically to
              determine the requirement for payment. Due to the Company's
              liquidity crisis since 1992 resulting from the loss of commercial
              viability of the domestic 2-D seismic licensing business, the
              Company ended many related contracts and operations. Payables from
              discontinued contracts over four years in age with no
              correspondence, negotiations or payments involving the vendor
              during the four year period for the particular payable in question
              exceed the statute of limitations whereby such accounts payable
              may be enforceable and have been written down by the Company.
              Formal settlements of liabilities resulting in reduced payment
              requirements were also recorded in this settlements/gain account
              and not against regular operations. At December 31, 1998, the
              Company anticipates no further settlement gains resulting from
              trade payables for which the statute of limitations will expire.

              During 1995 the Company established a $300,000 reserve for
              liabilities which had been written off in prior periods but which
              could possibly have been subject to future collection efforts by
              the creditors involved. Management subsequently determined that
              this reserve was no longer required as no such liabilities became
              known, nor were any asserted over the passage of time. Accordingly
              the reserve was decreased to $150,000 at December 31, 1997, and
              eliminated at December 31, 1998.

              REVENUE RECOGNITION

              Gross revenues for Company owned information (Data Library) are
              recognized when the information is transmitted to clients. Any
              related expenses incurred as a result of data licensing, such as
              commissions or revenue sharing arrangements, are expensed at the
              time revenues are recognized. In instances where the Company owns
              only a revenue interest in seismic data, then only the Company's
              net proceeds are recorded as revenue. The Company changed its
              accounting procedures effective January 1, 1998 to align itself
              with SEC policy. The effect was to allow the recognition of
              revenues when the materials licensed were completed products and
              available for delivery by the Company, but held temporarily at the
              request of the customer. This new policy would have had no impact
              on the 1995, 1996, or 1997 financial statements. In 1998, $36,000
              of revenues were recognized for data available for delivery but
              not picked up by the customer at year end.

              Third Party Data revenues are recognized when the information is
              transmitted to the clients. The Company assists certain of its
              clients in qualifying their seismic data licensing and trading

NOTE 1        SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

              Commission revenues are generated when the Company serves only as
              an agent for licensing geoscientific information owned by another
              company. Commission revenues are recognized on a pro rata basis as
              the completion of such firm orders progress.

              Reproduction and other revenue are recognized as the service is
              completed.

              NET INCOME (LOSS) PER SHARE

              Net income (loss) per share is computed by dividing net income
              (loss) by the common and common equivalent shares considered
              outstanding during each period. Equivalent shares issuable under
              stock options are determined using the treasury stock method.
              There is no difference between basic and fully diluted earnings
              per share for all periods presented.

                                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 3        DEBT (CONTINUED)

              During 1991, FIRST issued $2,240,000 of 12% senior notes. These
              notes required 10% principal payments annually for four years
              beginning December 31, 1992 along with a final 60% principal
              payment on December 31, 1996. Interest was payable quarterly.
              These notes are secured by FIRST's seismic data library. Only one
              scheduled 10% principal payment was paid to the noteholders.
              Subsequent to 1993, all payments made by FIRST were applied to the
              reduction of principal, due to the uncertainty of complete
              satisfaction of the debt. The outstanding principal balances at
              December 31, 1998, 1997, 1996 and 1995 were $1,031,496,
              $1,303,062, $1,410,607 and $1,668,919, respectively. The
              outstanding principal balance is past due. On October 7, 1997,
              FIRST offered a loan modification agreement to the holders of the
              notes.

              The loan modification agreement extends the maturity date of the
              notes to September 30, 1999, waives any and all unpaid interest,
              and at the option of FIRST can be converted into FIRST's common
              stock in one of three ways: FIRST may convert the outstanding
              principal balance to shares of the Company's common stock by
              dividing the average five day ask price of the public market
              trading price five days prior to the proposed exchange; FIRST may
              convert the outstanding principal balance valued at a stock price
              per share within forty-five days of a significant private
              placement; or FIRST may convert the outstanding principal balance
              at two times the actual net book value of FIRST's equity per share
              per the most recent quarterly financial statements immediately
              prior to such exchange.

              In addition to the loan modification agreement in 1998, FORTESA
              signed agreements with certain noteholders whereby their notes
              would be satisfied for a discounted amount. The substance of the
              transaction was for FORTESA to transfer funds to the Company to
              facilitate a payoff to the noteholders. The gain from the
              extinguishments of debt was $48,687 and is included in the
              $305,489 settlements/liability extinguishments on the Company's
              1998 statement of income and comprehensive income. With the
              intercession of FORTESA (See Note 10), all present holders of the
              12% senior notes accepted the loan modification agreement as of
              June 1998. Consequently, these amounts are classified as
              non-current in the accompanying balance sheets.

              During 1993, FIRST issued $500,000 of 6% notes. The 6% notes
              required interest only quarterly payments with the principal due
              in full, May 31, 1996. The 6% notes are secured by 100% of the
              stock of the Company's subsidiary for international information
              licensing, FEC. In addition, the 6% noteholders received 500,000
              warrants to purchase the Company's common stock at $.50 per share
              expiring June 1, 2000. Total assets and equity of FEC at December
              31, 1998 were $1,117,300 and 474,069, respectively. The
              outstanding principal balance of these 6% notes amounted to
              $411,178 at December 31, 1998, 1997 and 1996 and $421,178 at
              December 31, 1995. On December 28, 1998, the Company offered to
              exchange the principal and interest balances owed on the 6% notes
              for equity in the Company contingent upon at least 80% of the
              warrants held by these 6% noteholders being exercised early. As of
              October 1999, all of the 6% noteholders had accepted this offer.

                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 3        DEBT (CONTINUED)

              The $100,000 convertible debenture, which matured on June 30,
              1991, was reissued with interest at the rate of 10% payable
              semi-annually, maturing June 30, 1992. On September 12, 1997,
              interest was waived and the debenture was converted into 100,000
              shares of the Company's common stock. Consequently, this amount is
              classified as non-current in the accompanying 1996 and 1995
              balance sheets.

              On May 17, 1993, FIRST entered into a settlement agreement with a
              vendor for $300,000. The terms of the agreement have been modified
              several times due to the Company's liquidity crisis. In September
              1997, FIRST renegotiated the terms of the vendor settlement
              agreement which then had a $205,000 balance. A payment of $30,000
              was paid on September 30, 1997, $100,000 was paid on December 15,
              1997 and the $75,000 balance was paid by December 15, 1998.
              Therefore, the outstanding principal balance at December 31, 1998,
              1997 and 1996 was $0, $75,000 and $205,000, respectively.

NOTE 4        STOCKHOLDERS' EQUITY

              The Company is authorized to issue up to 10,000,000 shares of
              common stock with a par value of $.01 per share and up to
              1,000,000 shares of preferred stock with a par value of $1.00 per
              share. At a meeting held on January 7, 1999 the Board of Directors
              recommended re-establishing the original 1990 authorized
              capitalization, which was 20,000,000 common shares and 10,000,000
              preferred shares. A majority of the shareholders is required to
              approve this transaction.

              STOCK RIGHTS OUTSTANDING

              EMPLOYEE STOCK OPTION PLAN - In July 1990, the Company reserved
              500,000 shares of common stock for issuance under its Employee
              Stock Option Plan. All Incentive Stock Options ("ISO's") will be
              granted to employees at an exercise price of not less than the
              fair market value of the stock on the date of grant. All
              Non-incentive Stock Options ("NSO's") will be granted at an
              exercise price of not less than 85% of the fair market value of
              the stock on the date of grant. The Company and the Board's
              Compensation Committee, on February 3, 1998, re-assigned the
              entire 500,000 options from terminated employees to current
              employees of the Company. The strike price was set at $.20 per
              share. The fair market value was difficult to access due to the
              fact that the Company's common stock is traded on the pink sheets
              which is not a clear indicator of fair market value. Of the
              500,000 shares granted, the Company's President was granted
              300,000 shares or 60% of the total available. Due to the Company's
              liquidity requirements in August 1998, the President agreed to
              exercise all of his options, thereby infusing $60,000 of cash into
              the Company. As a further inducement for the early exercise of
              these options, the Company granted the President a security
              interest in its tangible personal property. The remaining 200,000
              options are outstanding at December 31, 1998.

                                           DECEMBER 31, 1998, 1997, 1996 & 1995
- - -------------------------------------------------------------------------------

NOTE 4        STOCKHOLDERS' EQUITY (CONTINUED)

              DIRECTOR STOCK OPTIONS - In July 1990, the Company also reserved
              150,000 shares of common stock for issuance under its Directors'
              Stock Option Plan. All options will be granted to non-employee
              directors at an exercise price of not less than the fair market
              value on the date of grant.

              NOTEHOLDERS WARRANTS - Warrants are outstanding to the 6%
              Noteholders Group for 500,000 shares at $.50 per share which
              expire June 1, 2000. The Company's offer of December 28, 1998 to
              the 6% noteholders would call for early exercise of most of these
              warrants (see Note 3) and cause the issuance of the same number of
              new warrants to these warrant holders (see Note 10).

NOTE 5        TRANSACTIONS WITH RELATED PARTIES

              During the period 1993 until 1996, the President of the Company
              had not received his contracted salary amount in cash compensation
              due to the Company's cash liquidity problems. The unpaid salary
              was accrued. In December 1996, the President entered into an
              agreement to purchase 253,000 shares of common stock at $0.02 cash
              per share and to forego the $253,000 compensation due him, for a
              total value increase to the Company of $258,860. The accompanying
              financial statements reflect this agreement to forego cash
              compensation, and to reflect the issuance of stock.

              In 1993, a limited partnership ("LTD") was established and the
              Company's President agreed to act as the general partner of this
              enterprise. LTD was founded to make investments in oil and gas
              exploration, development, reserves, and to make financing
              investments to facilitate portions of the Company's business plan
              that were outside of the financing capabilities of the Company.

              The 15 owners of LTD are all shareholders or noteholders of the
              Company. The Company itself also owns a minority percentage of
              LTD, granted for data use positions extended by the Company to LTD
              for the benefit of LTD leasing land in East Texas over one of the
              Company's prospects for natural gas. LTD funded all of the cash to
              acquire those leases, resulting in the Company having a 33%
              interest in the prospect and LTD having a 12% interest for its
              lease money and reimbursable data use rights expended thereon.
              However, it was LTD's cash extended to lease acreage that enabled
              the Company to complete the cycle to obtain the exclusive drilling
              rights to the first of the five prospects in East Texas generated
              in which the Company has an interest.

- - -------------------------------------------------------------------------------

NOTE 5        TRANSACTIONS WITH RELATED PARTIES (CONTINUED)

              In 1993, the Company sold one license for its East Texas data-set
              to LTD, prior to posting that data-set for sale for the benefit of
              the Senior Noteholders, LTD agreed to pay a total of $100,000 on
              terms of $16,000 cash advanced to the Company and the $84,000
              balance to be paid if the Company successfully promotes the East
              Texas prospect(s) and receives reimbursement for seismic data
              costs from the promoted incoming partners. The Company
              successfully leased the prospect but elected not to promote it
              until a 3-D seismic survey could be arranged over the prospect.
              The Company was successful in arranging for a 3-D seismic survey
              over this acreage in 1997. The 3-D seismic data was interpreted in
              1998 and indicated only moderate commercial viability. The
              Company's $84,000 contingent receivable is not reflected in the
              financial statements, and will be reported as a gain in the year
              received from LTD, if the Company promotes this first, or one of
              the other prospects successfully with seismic costs reimbursed.

              On January 1, 1997, the Company issued 150,000 shares of its
              common stock at par value to its Executive Vice President in
              exchange for all of the shares of Blackwell Supply, Inc. Blackwell
              is used to conduct the domestic geophysical activity of the
              Company, including its airborne remote sensing surveys. (See
              Note 1)

              During 1998 and 1997, the Company provided office space and
              administrative services to FORTESA at no charge.

              In March 1998, a company controlled by the President leased a
              laser copier to the Company for a period of 24 months at $424 per
              month on terms substantially identical to those paid by the
              President's company. The Company required use of the machine in
              connection with its new geologic report publishing business. At
              the end of the lease term, the Company will own the copier.

              See Note 10 for additional disclosures of related party
              transactions which occurred after 1998.

NOTE 6        COMMITMENTS

              The Company entered into an agreement with a major oil company to
              use certain geo-scientific information to create a synthesized
              study of current interest to the industry. Among other things, the
              agreement requires the Company to make five annual payments,
              depending on the level of sales, starting December 31, 1996
              through December 31, 2000. The minimum payments required are
              $75,000, $75,000, $75,000, $25,000 and $25,000, respectively. In
              1997, the agreement was amended satisfying the December 31, 1997
              payment of $75,000 through performance of consulting services by
              the Company and $60,000 of the $75,000 due in 1998 were paid as of
              December 31, 1998. In 1999, the agreement was further amended
              satisfying the final $75,000, $25,000, and $25,000 minimum
              payments through successful 1998 performance of consulting
              services by the Company for this major oil company.

              LEASES

              The Company leases office space under noncancelable operating
              lease agreements. Rent expense for the years ended December 31,
              1998, 1997, 1996 and 1995 was $118,602, $67,136, $71,835 and
              $62,442, respectively. The Company leases office space until March
              2000 for FEL and January 2001 for FEC.

              The minimum rental commitment under these leases, as currently
              modified to reflect the subsequent amendment/extension of lease
              agreements, at December 31, 1998 is as follows:

NOTE 7        INCOME TAXES (CONTINUED)

              No income tax is expensed as the Company is in an NOL Carryforward
              position and has been charging income against prior losses on its
              income tax return. The difference between the effective rate of
              income tax expense and the amount which would be determined by
              applying the statutory U.S. income tax rates to income before
              income tax expense is explained below according to the tax
              implications of the various items of income or expense:

              Although the Company has reported taxable income in each of the
              past four years, management believes there is a greater than 50%
              possibility that the deferred tax assets may not be realized with
              the next fiscal year; therefore, a valuation allowance has been
              established to offset these assets. If the proposed restructuring
              succeeds, including the merger of Fortesa into the Company, and
              successful development of its Senegal, West Africa gas field, the
              Company believes the future tax benefit resulting from its net
              operating losses will be more substantially realizable.
              Consequently, the valuation account may be substantially reduced
              depending upon the effects of the restructuring and acquisition of
              Fortesa. A significant increase in equity would result at that
              time.

NOTE 8        FAIR VALUES (CONTINUED)

              The following methods and assumptions were used to estimate the
              fair value of each class of financial instruments for which it is
              practical to estimate fair value.

              Cash and cash equivalents - The carrying amount approximates fair
              value because of the short maturity of those instruments.

              Long-term debt - The fair value is based upon discounting the debt
              such that the effective interest rate is prime plus 1% (9.5%)
              utilizing actual and intended repayments. No discount was applied
              to the convertible debenture.

              -    Conversion of the entire outstanding 6% Note balance
                   ($448,285 including accrued interest as of December 31,
                   1998) into 977,508 FIRST common shares.

              -    Early exercise of a minimum of 400,000 of the 6%
                   Noteholders' 500,000 $0.50/share warrants (at an effective
                   price of $0.33 per share) and issuance of a new $0.30 per
                   share warrant in exchange for each $0.50/share warrant
                   exercised early.

              -    Issuance of an additional number of shares of common stock
                   equal to 50% of the number of shares issued in connection
                   with the $.50 warrants.

              -    Merger of FORTESA into FIRST, and the changing of FIRST'S
                   name to FORTESA.

              -    Conversion of 100% of the outstanding (55) FIRST 12 % Senior
                   Notes into 1,241,596 FIRST common shares, as provided for in
                   the existing October 7, 1997 Loan Modification Agreements
                   with each of said 12% Noteholders.

              All of the 6% Noteholders agreed to the offer to convert, and the
              key elements of this restructuring program were completed on the
              30th of March 1999. To date, 475,000 of the $.50 and $.33 warrants
              have been exercised. Common stock was issued to both the 12% and
              the 6% Noteholders. Concurrently with this extinguishing of all of
              the Company's long-term debt, the Company acquired FORTESA
              Corporation from the President of the Company. This included a
              working interest in a commercially viable gas discovery in
              Senegal, West Africa with a carried interest to allow the pipeline
              to be connected to the local market, and most existing Warrant
              Holders exercised causing a cash infusion of $237,000 of new
              working capital.

              The President sold FORTESA at his cost basis to the Company for
              50,000 shares of a special convertible preferred stock in the
              Company and 8,055 shares of common stock. These preferred shares
              are convertible into not less than 500,000 common shares and not
              more than 2 million common shares, based on 40% of the net value
              actually realized by the Company from FORTESA assets over the
              ensuing five-year period. The Company will have to either 1)
              purchase additional shares in the open market as Treasury Stock,
              or 2) increase its authorized number of common shares in the
              future to honor an ultimate conversion by the President of the
              Preferred Stock to common, should the FORTESA assets cause the
              subsequent issuance of the additional 1,500,000 shares of Common
              Stock to the President as a result of successful value increase of
              FORTESA assets. Regarding the West African working interest,
              FORTESA had paid for all the technical costs of defining and
              presenting the geoscientific basis for the gas development
              project, and the Company had paid for communication thereof to
              potential partners in return for the right to acquire the results.

                                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                           DECEMBER 31, 1998, 1997, 1996 & 1995

NOTE 10       SUBSEQUENT EVENTS (CONTINUED)

              A firm commitment for $5,400,000 in development expenditures was
              obtained from a third party co-venturer in January 1998. This
              partner commenced expenditures in the first quarter of 1998 to
              advance the commercial exploitation of the 1997 Senegalese Gas
              Discovery, including the position of FORTESA and its co-venturers
              in this development project. FORTESA is not required to expend any
              development funds until the $5,400,000 has been expended. FORTESA
              owns a 15% working interest in the entire development project,
              after project payout, and benefits from 7.5% (50% of 15%) of the
              project's cash flow after production costs prior to payout of the
              $5,400,000 of carried development expenditures. The discovery well
              made in January 1997 on the block indicated a minimum of 2 BCF of
              reserves in just this first well. (See Note 5)

              The FORTESA acquisition will be accounted for similarly to a
              pooling of interests using the historical cost basis of the
              President.

              During 1999, oil prices fell dramatically. As a result, the
              Company's database of exploration materials and opportunities was
              temporarily impaired for licensing to the exploration industry, as
              many of those companies suffered significantly reduced capital
              expenditure budgets. The Company has adjusted during the period
              subsequent by suspending most all new projects, and seeking to
              deliver contract services using its experienced staff directly to
              certain of its oil industry customers. Revenues in the first half
              of 1999 were at very low levels, below that necessary to sustain
              the Company. Prices have subsequently recovered. The Company
              believes that revenues for the balance of 1999 will be adequate to
              recover the momentum enjoyed by the Company in 1998.

NOTE 11       LEGAL PROCEEDINGS

              The Company is a defendant in a lawsuit brought by two parties
              claiming to be the successors-in-interest to McKenzie Management
              Inc., a minority owner of certain seismic data acquired by the
              Company in September 1990 from McMoRan Oil & Gas Company and Adobe
              Resources Corporation. The data was originally owned by a joint
              venture comprised of McMoRan, Adobe and McKenzie Management Inc.
              At the time of its assignment to the Company, McMoRan and Adobe
              could not locate McKenzie and indemnified the Company "against any
              and all future claims, costs, expenses or causes of action that
              may be asserted by the referenced minority owner...." In June
              1994, the Company resold the data to Seitel Corporation and
              indemnified Seitel against claims relating to the seismic data
              being sold. The plaintiffs seek approximately $600,000 to
              $1,500,000, plus punitive damages and attorney's fees.

NOTE 11       LEGAL PROCEEDINGS (CONTINUED)

              Management believes it is indemnified against loss based on its
              purchase contract with McMoRan and Adobe. The Company has hired
              defense counsel and has made demand on IMC Global (as successor to
              McMoRan) and Santa Fe Resources (as successor to Adobe) to honor
              the indemnity running to First Seismic, but so far they have
              refused. Merits discovery is just commencing and it cannot be
              predicted what, if any, liability the Company may ultimately have
              in the case. The Company intends to offer a vigorous defense based
              on several theories including statute of limitations, and a claim
              the McKenzie did not even own an interest in all the subject
              seismic data. No specific provision has been recorded in the
              accompanying financial statements for any loss which may be
              realized from this matter.

              in investment in oil and gas prospects on the balance sheet and
              is a reduction in the amount due from Fortesa.

              During 1998 the Company financed the purchase of an automobile
              with an $11,940 note payable.

NOTE 15       STOCK OPTIONS AND WARRANTS

              The Company has elected to follow Accounting Principles Board
              Opinion No. 25, "Accounting for Stock Issued to Employees (APB
              25) and related interpretations in accounting for its employee
              stock options. Under APB 25, because the exercise price of
              employee stock options is equal to the estimated market price of
              the underlying stock on the date of grant, no compensation
              expense is recorded. The Company has adopted the disclosure-only
              provisions of Statement of Financial Accounting Standards No.
              123, Accounting for Stock-Based Compensation. The value of
              options and warrants granted during 1998 as computed under SFAS
              123, is deemed insignificant.

              The following summarizes the option and warrant activity and
              balances for the year ended December 31, 1998:

              At December 31, 1998, outstanding options and warrants consisted

           (a)  NOTICE AND DEFENSE.  The Indemnified Party will give the
party obligated to indemnify the Indemnified Party under this Article VI
(referred to in this Section as the "Indemnifying Party") prompt written
notice of any such Third Party Claim, and the Indemnifying Party may
undertake the defense thereof by representatives chosen by the Indemnifying
Party upon written notice to the Indemnified Party provided within 20 days of
receiving notice of such Third Party Claim (or sooner if the nature of the
Third Party Claim so requires and an extension cannot be obtained with
minimal expense or cost). Failure of the Indemnified Party to give such
notice shall not affect the indemnification obligations under this Article

of the Indemnifying Party and its representatives in defending any such claim,

after notice of any such Third Party Claim (or sooner if the nature of any
Third Party Claim so requires), fails to undertake the defense of such Third
Party Claim actively and in good faith, then the Indemnified Party will have
the right to undertake the defense, compromise or settlement of such Third
Party Claim, or consent to the entry of a judgment with respect thereto.

           (c)  INDEMNIFIED PARTY'S RIGHTS.  Anything in this Article VI to
the contrary notwithstanding, (i) if there is a reasonable probability that
the Third Party Claim may materially adversely affect the Indemnified Party
other than as a result of money damages and such Third Party Claim is
reasonably likely to result in money payments in an aggregate amount of less
than $2,500, the Indemnified Party shall have the right to defend, compromise
or settle such Third Party Claim (provided that the Indemnified Party shall
not settle such Third Party Claim or consent to any judgment without first
obtaining the written consent of the Indemnifying Party, which shall not be
unreasonably withheld), and (ii) the Indemnifying Party shall not without the
written consent of the Indemnified Party, settle or compromise any Third
Party Claim or consent to the entry of any judgment that does not include as
an unconditional term thereof the giving by the claimant or the plaintiff to

respect of such Third Party Claim.

                                   ARTICLE V

     For the management of the business and for the conduct of the affairs of
the Corporation, and in further creation, definition, limitation and
regulation of the powers of the Corporation and of its directors and of its
stockholders, it is further provided.

     Section 1.  ELECTIONS OF DIRECTORS.  Elections of Directors need not be
by written ballot unless the By-Laws of the Corporation shall so provide.

     Section 2.  NUMBER, ELECTION, AND TERMS OF DIRECTORS.  Except as
otherwise fixed pursuant to the provisions of Article IV hereof relating to
the rights of the holders of any class or series of stock having a preference
over the Common Stock as to dividends or upon liquidation to elect additional
directors under specified circumstances, the number of directors of the
Corporation shall be fixed from time to time by or pursuant to the By-Laws,
provided, however, that the number of directors shall at no time be less than
three nor greater than nine. The directors, other than those who may be
elected by the holders of any class or series of stock having preference over
the Common Stock as to dividends or upon liquidation, shall be classified,
with respect to the time for which they severally hold office, into three
classes, as nearly equal in number as possible, as shall be provided in the
manner specified in the By-Laws, Class I to hold office initially for a term
expiring at the annual meeting of stockholders to be held during the fiscal
year ending in 1991, Class II to hold office initially for a term expiring at
the annual meeting of stockholders to be held during the fiscal year ending
in 1992, and Class III to hold office initially for a term expiring at the
annual meeting of stockholders to be held during the fiscal year ending in
1993, with the members of each class to hold office until their successors
are elected and qualified. At each annual meeting of the stockholders of the
Corporation, the successors to the class of directors whose term expires at
that meeting shall be elected to hold office for a term expiring at the
annual meeting of stockholders held in the third year following the year of
their election.

     Section 3.  STOCKHOLDER NOMINATION OF DIRECTOR CANDIDATES.  Advance
notice of nominations for the election of


                                     -4-
<PAGE>

directors, other than by the Board of Directors or a Committee thereof, shall
be given in the manner provided in the By-Laws.

     Section 4.  NEWLY CREATED DIRECTORSHIPS AND VACANCIES.  Except as
otherwise fixed pursuant to the provisions of Article IV hereof relating to
the rights of the holders of any class or series of stock having a preference
over the Common Stock as to dividends or upon liquidation to elect directors
under specified circumstances, newly created directorships resulting from any
increase in the number of directors and any vacancies on the Board of
Directors resulting from death, resignation, disqualification, removal or
other cause shall be filled solely by the affirmative vote of a majority of
the remaining Directors then in office, even though less than a quorum of the
Board of Directors. Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the new directorship was created or the vacancy occurred
and until such director's successor shall have been elected and qualified. No
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

     Section 5.  REMOVAL OF DIRECTORS.  Subject to the rights of any class or
series of stock having preference over the Common Stock as to dividends or
upon liquidation to elect directors under specified circumstances, any
director may be removed from office without cause only by the affirmative
vote of the holders of two-thirds (66.67%) of the combined voting power of
the then outstanding shares of stock entitled to vote generally in the
election of directors, voting together as a single class.

     Section 6.  STOCKHOLDER ACTIONS.  Any action required or permitted to be
taken by the stockholders of the Corporation must be effected at a duly
called annual or special meeting of such stockholders and may not be effected
by any consent in writing by such stockholders. Except as otherwise required
by law and subject to the rights of the holders of any class or series of
stock having a preference over the Common Stock as to dividends or upon
liquidation, special meetings of stockholders of the Corporation may be
called only by the Chairman of the Board, the President or the Board of
Directors pursuant to a resolution approved by a majority of the entire Board
of Directors.

     Section 7.  BY-LAW AMENDMENTS.  The Board of Directors shall have power
to make, alter, amend and repeal the By-Laws (except so far as the By-Laws
adopted by the stockholders shall otherwise provide). Any By-Laws made by the
directors under the powers conferred hereby may be altered, amended or
repealed by the directors or by the stockholders. Notwithstanding the
foregoing and anything contained in this Certificate of Incorporation to the
contrary, Articles II and III of the By-Laws shall not be altered, amended or
repealed and no provision


                                     -5-
<PAGE>

inconsistent therewith shall be adopted without the affirmative vote of the
holders of at least two-thirds (66.67%) of the voting power of all the shares
of the Corporation entitled to vote generally in the election of directors,
voting together as a single class.

     Section 8.  AMENDMENT, REPEAL, ETC.  Notwithstanding anything contained
in this Certificate of Incorporation to the contrary, the affirmative vote of
the holders of at least two thirds (66.67%) of the voting power of all shares
of the Corporation entitled to vote generally in the election of directors,
voting as a single class, shall be required to alter, amend, adopt any
provision inconsistent with, or repeal, this Article V or any provision
hereof.

     share of the outstanding shares of any class of Equity Security (as

(the "Voting Stock"), voting together as a single class (it being understood

                 Determination Date, whichever is higher.

                     (iii)  The consideration to be received by holders of a
     particular class of outstanding Voting Stock (including Common Stock)
     shall be in cash or in the same form as the Interested Stockholder has

     in the event of any stock dividend, stock split, combination of shares
     or similar event.

                     (iv)   After such Interested Stockholder has become an
     Interested Stockholder and prior to the consummation of such Business
     Combination: (a) except as approved by a majority of the Disinterested
     Directors, there shall have been no failure to declare and pay at the
     regular date therefor any full quarterly dividends (whether or not
     cumulative) on any outstanding stock having preference over the Common
     Stock as to dividends or upon liquidation; (b) there shall have been (1)
     no reduction in the annual rate of dividends paid on the Common Stock
     (except as necessary to reflect any subdivision of the Common Stock),
     except as approved by a majority of the Disinterested Directors, and (2)
     an increase in such annual rate of dividends as necessary to reflect any
     reclassification (including any reverse stock split), recapitalization,
     reorganization or any similar transaction which has the effect of
     reducing the number of outstanding shares of the Common Stock, unless
     the failure to so increase such annual rate is approved by a majority of
     the Disinterested Directors; and (c) such Interested Stockholder shall
     have not become the beneficial owner of any additional shares of Voting
     Stock except as part of the transaction which results in such Interested
     Stockholder becoming an Interested Stockholder.

                     (v)    After such Interested Stockholder has become an
     Interested Stockholder, such Interested Stockholder shall not have
     received the benefit, directly or indirectly (except proportionately as
     a stockholder), of any loans, advances, guarantees, pledges or other
     financial assistance or any tax credits or other tax advantages provided
     by the Corporation, whether in anticipation of or in connection with
     such Business Combination or otherwise.

                     (vi)   A proxy or information statement describing the
     proposed Business Combination and complying with the requirements of the
     Securities Exchange Act of 1934, as amended, and the rules and
     regulations thereunder (or any subsequent provisions replacing such Act,
     rules or regulations) shall have been mailed to public stockholders of
     the Corporation at least thirty (30) days prior to the consummation of
     such Business Combination (whether or not such proxy or information
     statement is required to be mailed pursuant to such Act or subsequent
     provisions).

     FIRST SEISMIC Corporation, a corporation organized and existing under

     DOES HEREBY CERTIFY:

     FIRST:  That at a meeting of the Board of Directors of FIRST SEISMIC

amendments of the Certificate of Incorporation of said corporation, declaring
said amendment to be advisable and calling a meeting of the stockholders of
said corporation for consideration thereof. The resolution setting forth the

     RESOLVED, that the Certificate of Incorporation of this corporation be
     amended by changing Article V, Section 4 and Section 6 so that, as

                 Except as otherwise fixed pursuant to the provisions of
                 Article IV hereof relating to the rights of the holders of
                 any class or series of stock having a preference over the
                 Common Stock as to dividends or upon liquidation to elect
                 directors under specified circumstances, newly created
                 directorships resulting from any increase in the number of
                 directors and any vacancies on the Board of Directors
                 resulting from death, resignation, disqualification, removal
                 or other cause shall be filled solely by the affirmative
                 vote of a majority of the remaining Directors then in
                 office, even though less than a quorum of the Board of
                 Directors; provided that any vacancy created by a removal of
                 a director of the Corporation pursuant to Section 5 of this
                 Article V may be filled by action of the stockholders taken
                 at the same meeting at which the vacancy was created. Any
                 director elected in accordance with the preceding sentence
                 shall hold office for the remainder of the full term of
                 the class of directors in which the new directorship was
                 created or the vacancy occurred and until such director's
                 successor shall have been elected and qualified. No decrease
                 in the number of directors

                 constituting the Board of Directors shall shorten the term

                 must be effected at a duly called annual or special meeting
                 of such stockholders and may not be effected by any consent
                 in writing by such stockholders. Except as otherwise
                 required by law and subject to the rights of the holders of
                 any class or series of stock having a preference over the
                 Common Stock as to dividends or upon liquidation, special
                 meetings of stockholders of the Corporation may be called

                 stock of the Corporation issued and outstanding and entitled
                 to vote. Such request shall state the purpose or purposes of
                 the proposed meeting.

Directors, a special meeting of the stockholders of said corporation was duly
called and held, upon notice in accordance with the General Corporation Law
of the State of Delaware at which meeting the necessary number of shares were

provisions of Section 242 of the General Corporation Law of the State of
Delaware.

or by reason of said amendment.

                                     Bylaws

                                   Article I

                                    OFFICES

        The registered office of FIRST SEISMIC Corporation (the
"Corporation") in the State of Delaware shall be in the City of Wilmington,
County of New Castle, State of Delaware. The Corporation shall have offices
at such other places as the Board of Directors may from time to time
determine.

                                   Article II

                                  STOCKHOLDERS

Section 1. ANNUAL MEETINGS.

        The annual meeting of the stockholders for the election of Directors and
for the transaction of such other business as may properly come before the
meeting shall be held on such date as the Board of Directors shall each year
fix. Each such annual meeting shall be held at such place, within or without the
State of Delaware, and hour as shall be determined by the Board of Directors.
The day, place and hour of each annual meeting shall be specified in the notice
of such annual meeting. Any annual meeting of stockholders may be adjourned from
time to time and place to place until its business is completed.

Section 2. BUSINESS CONDUCTED AT MEETINGS.

        At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be (a) specified in the notice
of meeting (or any supplement thereto) given by or at the direction of the Board
of Directors, (b) otherwise properly brought before the meeting by or at the
direction of the Board of Directors, or (c) otherwise properly brought before
the meeting by a stockholder. For business to be properly brought before an
annual meeting by a stockholder, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the Corporation, not less than sixty days nor
more than ninety days prior to the meeting; provided, however, that in the event
that less than seventy days' notice or prior public disclosure of the date of
the meeting is given or made to stockholders, notice by the stockholder to be
timely must be so



<PAGE>

received not later than the close of business on the tenth day following the
date on which such notice of the date of the annual meeting was mailed or
such public disclosure was made. A stockholder's notice to the Secretary
shall set forth as to each matter the stockholder proposes to bring before
the annual meeting (a) a brief description of the business desired to be
brought before the annual meeting, (b) the name and address, as they appear
on the Corporation's books, of the stockholder proposing such business, (c)
the class and number of shares of the Corporation which are beneficially
owned by the stockholder, and (d) any material interest of the stockholder in
such business. Notwithstanding anything in the Bylaws to the contrary, no
business shall be conducted at an annual meeting except in accordance with
the procedures set forth in this Section 2. The presiding officer of an
annual meeting shall, if the facts warrant, determine and declare to the
meeting that business was not properly brought before the meeting and in
accordance with the provisions of this Section 2, and if he should so
determine, he shall so declare to the meeting and any such business not
properly brought before the meeting shall not be transacted.

Section 3. SPECIAL MEETINGS.

        Except as otherwise required by law and subject to the rights of the
holders of any class or series of stock having a preference over the Common
Stock as to dividends or on liquidation, special meetings of the stockholders
may be called only by the Chairman of the Board, the President and Chief
Executive Officer, or the Board of Directors pursuant to a resolution approved
by a majority of the entire Board of Directors. The term "entire Board of
Directors", as used in these Bylaws, means the total number of Directors which
the Corporation would have if there were no vacancies.

Section 4. STOCKHOLDER ACTION:  HOW TAKEN.

        Any action required or permitted to be taken by the stockholders of the
Corporation must be effected at a duly called annual or special meeting of such
holders and may not be effected by any consent in writing by such stockholders.

Section 5. NOTICE OF MEETING.

        Written notice stating the place, date and hour of the meeting and, in
case of a special meeting, the purpose or purposes for which the meeting is
called, shall be given not less than ten nor more than sixty days before the
date of the meeting, except as otherwise required by statute or the Certificate
of Incorporation, either personally or by mail, prepaid telegram, telex,
cablegram, or radiogram, to each stockholder of record entitled to vote at such
meeting. If mailed, such notice shall be deemed to be given when deposited in
the United States mail, postage prepaid, addressed to the stockholder at his
address as


                                     -2-

<PAGE>

it appears on the stock records of the Corporation. If given personally or
otherwise than by mail, such notice shall be deemed to be given when either
handed to the stockholder or delivered to the stockholder's address as it
appears on the stock records of the Corporation.

Section 6. WAIVER.

        Attendance of a stockholder of the Corporation, either in person or by
proxy, at any meeting, whether annual or special, shall constitute a waiver of
notice of such meeting, except where a stockholder attends a meeting for the
express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. A written waiver of notice of any such meeting signed by a stockholder
or stockholders entitled to such notice, whether before, at or after the time
for notice or the time of the meeting, shall be equivalent to notice. Neither
the business to be transacted at, nor the purposes of, any meeting need be

stockholder. Such list shall be open to the examination of any stockholder for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten days prior to the meeting, either at a place within the city
where the meeting is to be held, which place shall be specified in the notice of

these Bylaws, the holders of not less than one-third of the shares entitled to

constitute a quorum, and the act of the majority of such quorum shall be deemed
the act of the stockholders. If a quorum shall fail to attend any meeting, the
chairman of the meeting may adjourn the meeting to another place, date or time.

        If a notice of any adjourned special meeting of stockholders is sent to
all stockholders entitled to vote thereat, stating that it will be held with
those present constituting a quorum, then, except as otherwise required by law,
those present at such adjourned meeting shall constitute a


                                     -3-


<PAGE>

quorum, and all matters shall be determined by a majority of votes cast at
such meeting.

Section 9. QUALIFICATION OF VOTERS.

        The Board of Directors may fix, in advance, a day and hour not more than
sixty nor less than ten days prior to the day of holding any meeting of the

term expiring at the annual meeting of stockholders to be held during the fiscal
year ending in 1992, and Class III to hold office initially for a term expiring
at the annual meeting of stockholders to be held during the fiscal year ending
in 1993, with the members of each class to hold office until their successors
are elected and qualified. At each annual meeting of stockholders, the
successors of the class of Directors whose term expires at that meeting shall be
elected to hold office for a term expiring at the annual meeting of stockholders
held in the third year following the year of their election.

nominations for the election of Directors may be made by the Board of Directors
or a committee appointed by the Board of Directors or by any stockholder
entitled to vote in the election of Directors generally. However, any
stockholder entitled to vote in the election of Directors generally may nominate
one or more persons for election as Directors at a meeting only if written
notice of such stockholder's intent to make such nomination or nominations has
been given, either by personal delivery or by United States mail, postage
prepaid, to the Secretary of the Corporation no later than (i) with respect to
an election to be held at an annual meeting of stockholders, ninety days prior
to the anniversary date of the immediately preceding annual meeting, and (ii)
with respect to an election to be held at a special meeting of stockholders for
the election of Directors, the close of business on the tenth day following the
date on which notice of such meeting is first given to stockholders. Each such
notice shall set forth: (a) the name and address of the stockholder who intends
to make the nomination and of the person or persons to be nominated; (b)
representation that the Stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice; (c) a description of all arrangements or understandings between the
stockholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nomination or nominations are to be made by
the stockholder; (d) such other information regarding each nominee proposed by
such stockholder as would be required to be included in a proxy statement filed
pursuant to the proxy rules of the Securities and Exchange Commission; and (e)
the consent of each nominee to serve as a Director of the Corporation if so
elected. The presiding officer of the meeting may refuse to acknowledge the
nomination of any person not made in compliance with the foregoing procedure.

Section 2. NEWLY CREATED DIRECTORSHIPS AND VACANCIES.

        Except as otherwise fixed pursuant to the provisions of Article IV of
the Certificate of Incorporation relating to the rights of the holders of any
class or series of stock having a preference over the Common Stock as to
dividends or upon liquidation to elect Directors under specified circumstances,
newly created directorships resulting from any increase in the number of
Directors and any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other cause shall be filled solely by
the affirmative vote of a majority of the remaining Directors then in office,
even though less than a quorum of the Board of Directors. Any Director elected
in accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of Directors in which the new directorship was
created or the


                                     -5-

vacancy occurred and until such Director's successor shall have been elected
and qualified. No decrease in the number of Directors constituting the Board
of Directors shall shorten the term of any incumbent Director.

Section 3. REMOVAL.

        Subject to the rights of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation to
elect Directors under specified circumstances, any Director may be removed from
office without cause, only by the affirmative vote of the holders of two-thirds
of the combined voting power of the then outstanding shares of stock entitled to
vote generally in the election of Directors, voting together as a single class.

Bylaws, the presence of a majority of the entire Board of Directors shall be
necessary and sufficient to constitute a quorum for the transaction of business

Officer, as it may from time to time determine. The Chairman of the Board shall
hold his position at the pleasure of the Board of Directors and may be removed
at any time by the Board of Directors with or without cause.

2.      DIVIDENDS.

        (a) The holders of Series A Preferred Stock, in preference to the
holders of Common Stock, shall be entitled to receive, but only out of any
funds legally available for the declaration of dividends, cumulative,
preferential dividends at an annual rate equal to six percent, payable
annually on or before the last calendar day of December in each year
following the Commencement Date in which the Series A Preferred Stock is
outstanding. Such dividends shall commence to accrue on the shares of Series
A Preferred Stock and be cumulative from and after March 31, 2001 (the
"Commencement Date") and shall be deemed to accumulate and accrue from each
year thereafter. So long as any shares of Series A Preferred Stock remain
outstanding, no dividends or distributions (other than dividends or
distributions on Common Stock payable in Common Stock) shall be paid

                                     -2-

<PAGE>


upon, or declared or set apart for, the Common Stock, nor shall any Common Stock
(other than Common Stock acquired in exchange for, or out of cash proceeds of,
the issue of other Common Stock or out of cash contributions to the capital of
the Corporation) be purchased, redeemed, retired or otherwise acquired by the
Corporation, unless and until in either case all past due, cumulative dividends
on the then outstanding shares of Series A Preferred Stock for all past dividend
periods shall have been or concurrently shall be paid.


        (b) Upon any consummation of (i) a Qualified Public Offering; (ii) a
merger or consolidation involving the Corporation or (iii) a Change of Control,
the Corporation shall pay on the date of such consummation all accrued and
unpaid dividends as of such date on all outstanding Series A Preferred Stock.

3.      DISTRIBUTIONS UPON LIQUIDATION, DISSOLUTION OR WINDING UP.

        In the event of any voluntary or involuntary liquidation, dissolution or
other winding up of the affairs of the Corporation, before any distribution or
payment shall be made to the holders of Common Stock or to holders of any Junior
Stock, the holders of the Series A Preferred Stock shall be entitled to be paid
the Liquidation Preference on all outstanding shares of the Series A Preferred
Stock as of the date of such liquidation or dissolution or such other winding
up, plus any accrued but unpaid dividends, if any, to such date, and no more.
If, upon any such liquidation, dissolution or other winding up of the affairs of
the Corporation, the net assets of the Corporation distributable among the
holders of all outstanding shares of the Series A Preferred Stock and of any
Parity Stock shall be insufficient to permit the payment in full to such holders
of the preferential amounts to which they are entitled, then the entire net
assets of the Corporation shall be distributed among the holders of the Series A
Preferred Stock and the holders of any Parity Stock ratably in proportion to the
full amounts to which they would otherwise be respectively entitled. Neither the
consolidation or merger of the Corporation into or with another corporation or
corporations, nor the sale of all or substantially all of the assets of the
Corporation to another corporation or corporations shall be deemed a
liquidation, dissolution or winding up of the affairs of the Corporation within
the meaning of this Paragraph 3.

4.      REDEMPTION BY THE CORPORATION.

        (a) The Series A Preferred Stock shall not be redeemed in whole or in
part prior to March 31, 2004. On or after March 31, 2004, the Corporation may,
at its option, redeem in cash at any time in whole but not in part the Series A
Preferred Stock at the Redemption Price per share.

        (b) Notice of redemption of the Series A Preferred Stock shall be sent
by or on behalf of the Corporation, by first class mail, postage prepaid, to the
holders of record of the outstanding shares of Series A Preferred Stock at their
respective addresses as they shall appear on the records of the Corporation, not
less than thirty (30) days nor more than sixty (60) days prior to the date fixed
for redemption (the "Redemption Date") (i) notifying such holders of the
election of the Corporation to redeem such shares and of the date of redemption,
(ii) stating the date on which the shares cease to be convertible, and the
Conversion Price (as defined herein) and (iii) the place or places at which the
shares called for redemption shall, upon presentation and surrender of the
certificates evidencing such shares, be redeemed, and the Redemption Price
therefor.

        (c) If notice of redemption shall have been given as herein provided
each holder of shares called for redemption shall be entitled to all
preferences, relative and other rights accorded by this resolution until and
including the Redemption Date.

5.      CONVERSION RIGHTS. The Series A Preferred Stock shall be convertible
into Common Stock as follows:

        (a) CONVERSION AT HOLDER'S OPTION. The holder of any shares of the
Series A Preferred Stock shall have the right at such holder's option, at any
time after March 31, 2001 and without the payment of any additional
consideration, to convert any or all of such shares of the Series A Preferred
Stock into fully paid and nonassessable shares of Common Stock upon the terms
hereinafter set forth.

        (b) NUMBER OF SHARES. In the event of a conversion pursuant to
subparagraph 5(a) above, each share of the Series A Preferred Stock so converted
shall be converted into such number of shares of Common Stock as is determined
by dividing (x) the Liquidation Price by (y) the Conversion Price in effect on
the effective date of the conversion (the "Conversion Date"). The initial
Conversion Price shall be $0.10 per share of Common Stock (the "Initial
Conversion Price"). Such initial Conversion Price shall be subject to adjustment
in order to adjust the number of shares of Common Stock into which the Series A
Preferred Stock is convertible, as hereinafter provided.

        (c) CONVERSION PRICE ADJUSTMENTS. The Conversion Price shall be subject
to adjustment from time to time as follows:

                (i) ADJUSTMENT AT THE OPTION OF THE HOLDER. Upon the calculation
        of the Attributable Value for each of the years ending December
        31, 2001, 2002, and 2003 the Conversion Price in effect immediately
        prior to such calculation shall immediately be reduced to the price
        determined by dividing the Conversion Price in effect immediately prior
        to such calculation by the sum of (x) one and (y) the Attributable Value
        divided by 975,000; PROVIDED that the Attributable Value is greater than
        zero; and PROVIDED FURTHER that the Conversion Price shall at no time be
        reduced to an amount less than the Initial Conversion Price, as adjusted
        according to Sections 5(c)(ii), (iv) and (v), divided by four. As used
        herein the term "Attributable Value" shall have the meaning as such term
        is described in that certain Stock Purchase Agreement between the
        Corporation and The Beall Living Trust dated as of March 31, 1999.

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

                (iii) OTHER DISTRIBUTIONS. In case the Corporation shall fix a
        record date for the making of a distribution to all holders of shares of
        its Common Stock (i) of shares of any class other than its Common Stock
        or (ii) of evidences of indebtedness of the Corporation or any
        subsidiary or (iii) of assets (including cash but excluding dividends or
        distributions referred to in subparagraph 5(c)(ii) above), or (iv) of
        rights or warrants, in each case the Conversion Price in effect
        immediately prior thereto shall be reduced immediately thereafter to the
        price determined by dividing (1) an amount equal


                                     -4-

<PAGE>

        to the difference resulting from (A) the number of shares of Common
        Stock outstanding on such record date multiplied by the Conversion Price
        per share on such record date, less (B) the fair market value (as
        determined by the Board, whose determination shall be conclusive) of
        said shares or evidences of indebtedness or assets or rights or warrants
        to be so distributed, by (2) the sum of the number of shares of Common
        Stock outstanding on such record date.  Such adjustment shall be made
        successively whenever such a record date is fixed. In the event that
        such distribution is not so made, the Conversion Price then in effect
        shall be readjusted, effective as of the date when the Board determines
        not to distribute such shares, evidences of indebtedness, assets, rights
        or warrants, as the case may be, to the Conversion Price which would
        then be in effect if such record date had not been fixed.

                (iv) ROUNDING OF CALCULATIONS; MINIMUM ADJUSTMENT.  All
        calculations under this subparagraph 5(c) shall be made to the nearest
        cent or to the nearest one hundredth (1/100th) of a share, as the case
        may be. Any provision of this Paragraph 5 to the contrary
        notwithstanding, no adjustment in the Conversion Price shall be made if
        the amount of such adjustment would be less than $0.001; but any such
        amount shall be carried forward and an adjustment with respect thereto
        shall be made at the time of and together with any subsequent adjustment
        which, together with such amount and any other amount or amounts so
        carried forward, shall aggregate $0.001 of more.

                (v) TIMING OF ISSUANCE OF ADDITIONAL COMMON STOCK UPON CERTAIN
        ADJUSTMENTS. In any case in which the provisions of this subparagraph
        5(c) shall require that an adjustment shall become effective immediately
        after a record date for an event, the Corporation may defer until the
        occurrence of such event (A) issuing to the holder of any share of the
        Series A Preferred Stock converted after such record date and before the
        occurrence of such event the additional shares of Common Stock issuable
        upon such conversion by reason of the adjustment required by such event
        over and above the shares of Common Stock issuable upon such conversion
        before giving effect to such adjustment and (B) paying to such holder
        any amount of cash in lieu of a fractional share of Common Stock
        pursuant to subparagraph 5(db); PROVIDED that the Corporation upon
        request shall deliver to such holder a due bill or other appropriate
        instrument evidencing such holder's right to receive such additional
        shares, and such cash, upon the occurrence of the event requiring such
        adjustment.

        (d) FRACTIONAL SHARES. No fractional shares of Common Stock or scrip
shall be issued upon conversion of shares of the Series A Preferred Stock.  If
more than one share of the Series A Preferred Stock shall be surrendered for
conversion at any one time by the same holder, the number of full shares of
Common Stock issuable upon conversion thereof shall be computed on the basis
of the aggregate number of shares of the Series A Preferred Stock so
surrendered. Instead of any fractional shares of Common Stock which would
otherwise be issuable upon conversion of any shares of the Series A Preferred
Stock, the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to that fractional interest of the
then Current Market Price, as defined in subparagraph 5(e) below.

        (e) CURRENT MARKET PRICE. The Current Market Price at any date shall
mean, in the event the Common Stock is publicly traded, the average of the
daily closing prices per share of Common Stock for ten (10) consecutive
trading days ending three (3) trading days before such date (as adjusted for
any stock dividend, split combination or reclassification that took effect
during such 10 trading day period). The closing price for each day shall be
the last reported sale price regular way or, in case no such reported sale
takes place on such day, the average of the last closing bid and asked prices
regular way, in either case on the principal national securities exchange on
which the Common Stock is listed or admitted to trading; or if not listed or
admitted to trading on any national securities exchange, the closing sale
price for such day reported by Nasdaq, if the Common Stock is traded
over-the-counter and quoted in the National Market System, or if the Common

                                     -5-

<PAGE>

Stock is so traded, but not so quoted, the average of the closing reported bid
and asked prices of the Common Stock as reported by Nasdaq or any comparable
system, or, if the Common Stock is not listed on Nasdaq or any comparable
system, the average of the closing bid and asked prices as furnished by two
members of the National Association of Securities Dealers, Inc. selected from
time to time by the Corporation for that purpose. If the Common Stock is not
traded in such manner that the quotations referred to above are available for
the period required hereunder, Current Market Price per share of Common Stock
shall be deemed to be the fair value per share of Common Stock as determined
in good faith by the Board of Directors, irrespective of any accounting
treatment.

        (f) STATEMENT REGARDING ADJUSTMENTS. Whenever the Conversion Price
shall be adjusted as provided in subparagraph 5(c), the Corporation shall
forthwith file, at the principal office of the Corporation, a statement
showing in detail the facts requiring such adjustment and the Conversion
Price that shall be in effect after such adjustment, and the Corporation
shall also cause a copy of such statement to be sent by mail, first class
postage prepaid, to each holder of shares of the Series A Preferred Stock at
its address appearing on the Corporation's records. Each such statement shall
be signed by the Corporation's chief financial officer. Where appropriate,
such copy may be given in advance and may be included as part of a notice
required to be mailed under the provisions of subparagraph 5(g).

        (g) NOTICE TO HOLDERS. In the event the Corporation shall propose to
take any action of the type described in clause (i) (but only if the action
of the type described in clause (i) would result in an adjustment in the
Conversion Price), (ii) or (iii) of subparagraph 5(c), or described in
subparagraph 5(k), the Corporation shall give notice to each holder of shares
of the Series A Preferred Stock, in the manner set forth in subparagraph
5(g), which notice shall specify the record date, if any, with respect to any
such action and the approximate date on which such action is to take place.
Such notice shall also set forth such facts with respect thereto as shall be
reasonably necessary to indicate the effect on the Conversion Price and the
number, kind or class of shares or other securities or property which shall
be deliverable upon conversion of shares of the Series A Preferred Stock.  In
the case of any action which would require the fixing of a record date, such
notice shall be given at least ten (10) days prior to the date so fixed, and
in case of all other action, such notice shall be given at least fifteen (15)
days prior to the taking of such proposed action. Failure to give such
notice, or any defect therein, shall not affect the legality or validity of
any such action.

        (h) MECHANICS OF CONVERSION. The holder of any shares of the Series A
Preferred Stock may exercise the conversion right specified in subparagraph
5(a) by surrendering to the Corporation the certificate or certificates
representing the shares of the Series A Preferred Stock to be converted,
accompanied by written notice specifying the number of such shares to be
converted. If the certificate representing shares of Common Stock issuable
upon conversion of shares of the Series A Preferred Stock is to be issued in
a name other than the name on the face of the certificate representing such
shares of the Series A Preferred Stock, such certificate shall be accompanied
by such evidence of the assignment and such evidence of the signatory's
authority with respect thereto as deemed appropriate by the Corporation and
such certificate shall be endorsed directly or through stock powers to the
Corporation or in blank.  Conversion shall be deemed to have been effected on
the date when delivery of notice of an election to convert pursuant to
subparagraph 5(a) and of certificates representing the shares being converted
is made (the "Conversion Date").  As promptly as practicable after the
Conversion Date, the Corporation shall issue and deliver to or upon the
written order of such holder a certificate or certificates for the number of
full shares of Common Stock to which such holder is entitled upon such
conversion. The person in whose name the certificate or certificates for
Common Stock are to be issued shall be deemed to have become a holder of
record of such Common Stock on the applicable Conversion Date. Upon
conversion of only a portion of the number of shares covered by a certificate
representing shares of Series A Preferred Stock surrendered for conversion,
the Corporation shall issue and deliver to or upon the

                                      -6-

<PAGE>

written order of the holder of the certificate so surrendered for conversion, at
the expense of the Corporation, a new certificate representing the number of
shares of the Series A Preferred Stock representing the unconverted portion of
the certificate so surrendered. The Corporation shall pay on any Conversion Date
all accrued and unpaid dividends (including any accrued but unpaid dividends
thereon) to and including such date on all shares of Series A Preferred Stock to
be so converted.

        (i) TREASURY STOCK. For the purposes of this Paragraph 5, the sale or
other disposition of any Common Stock theretofore held in the Corporation's
treasury shall be deemed to be an issuance thereof.

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

        (k) CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE. In case of any
consolidation with or merger of the Corporation with or into another corporation
or other entity, or in case of any sale, lease or conveyance to another
corporation or other entity of the assets of the Corporation as an entirety or
substantially as an entirety, each share of the Series A Preferred Stock shall
after the date of such consolidation, merger, sale, lease or conveyance be
convertible into the number of shares of stock or other securities or property
(including cash) to which the Common Stock issuable (at the time of such
consolidation, merger, sale, lease or conveyance, as if the Series A Preferred
Stock were then optionally convertible or mandatorily convertible, as the case
may be) upon conversion of such share of the Series A Preferred Stock would have
been entitled upon such consolidation, merger, sale, lease or conveyance; and in
any such case, if necessary, the provisions set forth herein with respect to the
rights and interests thereafter of the holders of the shares of the Series A
Preferred Stock (including without limitation the definition of Current Market
Price) shall be appropriately adjusted so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or property thereafter
deliverable on the conversion of the shares of the Series A Preferred Stock.

6.      VOTING RIGHTS.

        So long as any shares of Series A Preferred Stock remain outstanding,
the Corporation shall not, without the affirmative consent or approval of the
holders of shares representing at least 50% of the voting power of the Series A
Preferred Stock then outstanding, acting separately as one class: (i) amend,
alter or repeal (whether by merger, consolidation or otherwise) any of the
provisions of this Certificate of Designation or the Certificate of
Incorporation or the Bylaws of the Corporation, (ii) authorize or issue any
Senior Stock or Parity Stock; (iii) sell, lease or convey all, or substantially
all, of the assets of the Corporation; (iv) consummate any merger or
consolidation of the Corporation with any other entity, or (v) make any
Restricted Payment.

7.      EXCLUSION OF OTHER RIGHTS.

        Except as may otherwise be required by law, the shares of Series A
Preferred Stock shall not have any voting rights, preferences or relative,
participating, optional or other special rights, other than those specifically
set forth in this resolution (as such resolution may be amended from time to
time) and in the Corporation's Certificate of Incorporation.


                                     -7-

8.      HEADINGS OF SUBDIVISIONS.

        The headings of the various subdivisions hereof are for convenience of
reference only and shall not affect the interpretation of any of the provisions
hereof.

9.      SEVERABILITY OF PROVISIONS.

        If any right, preference or limitation of the Series A Preferred Stock
set forth in this resolution (as such resolution may be amended from time to
time) is invalid, unlawful or incapable of being enforced by reason of any rule
of law or public policy, all other rights, preferences and limitations set forth
in this resolution (as so amended) which can be given effect without the
invalid, unlawful or unenforceable right, preference or limitation shall,
nevertheless, remain in full force and effect, and no right, preference or
limitation herein set forth shall be deemed dependent upon any other such right,
preference or limitation unless so expressed herein.

10.     STATUS OF REACQUIRED SHARES.

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


        IN WITNESS WHEREOF, this Certificate has been duly executed by the
undersigned President and Secretary of the Corporation this 31 day of March
1999.

Stock.

        SENIOR STOCK. The term "Senior Stock" shall mean any other class or
series of stock of the Corporation ranking senior to the Series B Preferred
Stock in respect of the right to (a) redemption, (b) receive payment of
dividends or (c) receive assets upon liquidation, dissolution or winding up of
the affairs of the Corporation.

        SUBSIDIARY. The term "Subsidiary" shall mean any corporation of which
shares of stock possessing at least a majority of the general voting power in
electing the board of directors are, at the time as of which


<PAGE>

any determination is being made, owned by the Corporation, whether directly
or indirectly through one or more Subsidiaries.

2.      DIVIDENDS.

        The holders of Series B Preferred Stock shall be entitled to receive
dividends only if, and to the extent, declared by the Board of Directors in its
sole discretion.

3.      DISTRIBUTIONS UPON LIQUIDATION, DISSOLUTION OR WINDING UP.

        In the event of any voluntary or involuntary liquidation, dissolution or
other winding up of the affairs of the Corporation, before any distribution or
payment shall be made to the holders of Common Stock or to holders of any Junior
Stock, the holders of the Series B Preferred Stock shall be entitled to be paid
the Liquidation Preference on all outstanding shares of the Series B Preferred
Stock as of the date of such liquidation or dissolution or such other winding
up, plus any accrued but unpaid dividends (including any accrued but unpaid
dividends thereon), if any, to such date, and no more. If, upon any such
liquidation, dissolution or other winding up of the affairs of the Corporation,
the net assets of the Corporation distributable among the holders of all
outstanding shares of the Series B Preferred Stock and of any Parity Stock shall
be insufficient to permit the payment in full to such holders of the
preferential amounts to which they are entitled, then the entire net assets of
the Corporation shall be distributed among the holders of the Series B Preferred
Stock and the holders of any Parity Stock ratably in proportion to the full
amounts to which they would otherwise be respectively entitled. Neither the
consolidation or merger of the Corporation into or with another corporation or
corporations, nor the sale of all or substantially all of the assets of the
Corporation to another corporation or corporations shall be deemed a
liquidation, dissolution or winding up of the affairs of the Corporation within
the meaning of this Paragraph 3.

4.      REDEMPTION BY THE CORPORATION.

        (a) On or after the Issue Date, the Corporation may, at its option,
redeem in cash at any time in whole or in part the Series B Preferred Stock at
the Redemption Price per share or such lesser amount as the Corporation and 100%
of the Holders of shares of Series B Preferred Stock shall agree. If the
Corporation exercises its option to redeem any or all shares of Series B
Preferred Stock prior to three (3) years from the Issue Date, the Redemption
Price shall include an amount equal to dividends of 6% per annum for each share
of Series B Preferred Stock to be redeemed, which dividends shall be deemed to
accrue and accumulate from the Issue Date to the Redemption Date.

        (b) Notice of redemption of the Series B Preferred Stock shall be sent
by or on behalf of the Corporation, by first class mail, postage prepaid, to the
holders of record of the outstanding shares of Series B Preferred Stock at their
respective addresses as they shall appear on the records of the Corporation, not
less than thirty (30) days nor more than sixty (60) days prior to the date fixed
for redemption (the "Redemption Date") (i) notifying such holders of the
election of the Corporation to redeem such shares and of the date of redemption,
(ii) stating the date on which the shares cease to be convertible, and the
Conversion Price (as defined herein) and (iii) the place or places at which the
shares called for redemption shall, upon presentation and surrender of the
certificates evidencing such shares, be redeemed, and the Redemption Price
therefor.

                                      -3-


<PAGE>


        (c) If notice of redemption shall have been given as herein provided
each holder of shares called for redemption shall be entitled to all
preferences, relative and other rights accorded by this resolution until and
including the Redemption Date.

        5. CONVERSION RIGHTS. The Series B Preferred Stock shall be convertible
into Common Stock as follows:

        (a) CONVERSION AT HOLDER'S OPTION. The holder of any shares of the
Series B Preferred Stock shall have the right at such holder's option, at any
time after the Issue Date and without the payment of any additional
consideration, to convert any or all of such shares of the Series B Preferred
Stock into fully paid and nonassessable shares of Common Stock upon the terms
hereinafter set forth.

        (b) NUMBER OF SHARES. In the event of a conversion pursuant to
subparagraph 5(a) above, each share of the Series B Preferred Stock so converted
shall be converted into 10 fully paid and nonassessable shares of Common Stock
(the "Conversion Rate") upon satisfaction of the requirements set forth in
subparagraph 5(h). Such initial Conversion Rate shall be subject to adjustment
in order to adjust the number of shares of Common Stock into which the Series B
Preferred Stock is convertible, as hereinafter provided.

        (c) CONVERSION RATE ADJUSTMENTS. The Conversion Rate shall be subject to
adjustment from time to time as follows:

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

                (ii) COMMON STOCK ISSUED AT LESS THAN CONVERSION RATE. If the
        Corporation issues or sells any Common Stock other than Excluded Stock
        without consideration or for a consideration per share less than (x) the
        Conversion Rate in effect immediately prior to such issuance or sale
        divided by (y) the Liquidation Value, then the Conversion Rate in effect
        immediately prior to each such issuance or sale will immediately (except
        as provided below) be increased to the rate determined by multiplying
        the Conversion Rate in effect immediately prior to such issuance or sale
        by a fraction, (1) the numerator of which shall be the number of shares
        of Common Stock outstanding immediately after such issue or sale and (2)
        the denominator of which shall be (i) the number of shares of Common
        Stock outstanding immediately prior to such issuance or sale plus (ii)
        the number of shares of Common Stock which the aggregate consideration
        received by the Corporation for the total number of such additional
        shares of Common Stock so issued or sold would purchase at a price equal
        to (x) the Conversion Rate in effect immediately prior to such

                                      -4-

<PAGE>

        issuance or sale divided by (y) the Liquidation Value. For the purposes
        of any adjustment of the Conversion Rate pursuant to this Section
        5(c)(ii) the following provisions shall be applicable:

                        (A) in the case of the issuance of Common Stock for
                cash, the amount of the consideration received by the
                Corporation shall be deemed to be the amount of the cash
                proceeds received by the Corporation for such Common Stock
                before deducting therefrom any discounts or commissions allowed,
                paid or incurred by the Corporation for any underwriting or
                otherwise in connection with the issuance and sale thereof;

                        (B) in the case of the issuance of Common Stock
                (otherwise than upon the conversion of shares of Capital Stock
                or other securities of the Corporation) for a consideration in
                whole or in part other than cash, including securities acquired
                in exchange therefor (other than securities by their terms so
                exchangeable), the consideration other than cash shall be deemed
                to be the fair value thereof as reasonably determined by the
                Board, irrespective of any accounting treatment;

                        (C) in the case of the issuance of (a) options, warrants
                or other rights to purchase or acquire Common Stock (whether or
                not at the time exercisable), (b) securities by their terms
                convertible into or exchangeable for Common Stock (whether or
                not at the time so convertible or exchangeable) or options,
                warrants or rights to purchase such convertible or exchangeable
                securities (whether or not at the time exercisable):

                            (1)  the aggregate maximum number of shares of
                                 Common Stock deliverable upon exercise of
                                 such options, warrants or other rights to
                                 purchase or acquire Common Stock shall be
                                 deemed to have been issued at the time such
                                 options, warrants or rights are issued and
                                 for a consideration equal to the
                                 consideration (determined in the manner
                                 provided in Section 5(c)(ii)(A) and (B)), if
                                 any, received by the Corporation upon the
                                 issuance of such options, warrants or rights
                                 plus the minimum purchase price provided in
                                 such options, warrants or rights for the
                                 Common Stock covered thereby;

                            (2)  the aggregate maximum number of shares of
                                 Common Stock deliverable upon conversion of
                                 or in exchange for any such convertible or
                                 exchangeable securities, or upon the
                                 exercise of options, warrants or other
                                 rights to purchase or acquire such
                                 convertible or exchangeable securities and
                                 the subsequent conversion or exchange
                                 thereof, shall be deemed to have been issued
                                 at the time such securities were issued or
                                 such options, warrants or rights were issued
                                 and for a consideration equal to the
                                 consideration, if any, received by the
                                 Corporation for any such securities and
                                 related options, warrants or rights (excluding
                                 any cash received on account of accrued
                                 interest or accrued dividends), plus the
                                 additional consideration (determined in the
                                 manner provided in Section 5(c)(ii)(A) and
                                 (B)), if any, to be received by the
                                 Corporation upon the conversion or exchange
                                 of such securities, or upon the exercise of
                                 any related options,


                                     -5-

                                 warrants or rights to purchase or acquire such
                                 convertible or exchangeable securities and the
                                 subsequent conversion or exchange thereof;

                            (3)  on any change in the number of shares of
                                 Common Stock deliverable upon exercise of
                                 any such options, warrants or rights or
                                 conversion or exchange of such convertible
                                 or exchangeable securities or any change in
                                 the consideration to be received by the
                                 Corporation upon such exercise, conversion
                                 or exchange, but excluding changes resulting
                                 from the anti-dilution provisions thereof
                                 (to the extent comparable to the
                                 anti-dilution provisions contained herein),
                                 the Conversion Rate as then in effect shall
                                 forthwith be readjusted to such Conversion
                                 Rate as would have been obtained had an
                                 adjustment been made upon the issuance of
                                 such options, warrants or rights not
                                 exercised prior to such change, or of such
                                 convertible or exchangeable securities not
                                 converted or exchanged prior to such change,
                                 upon the basis of such change;

                            (4)  on the expiration or cancellation of any
                                 such options, warrants or rights (without
                                 exercise), or the termination of the right
                                 to convert or exchange such convertible or
                                 exchangeable securities (without exercise),
                                 if the Conversion Rate shall have been
                                 adjusted upon the issuance thereof, the
                                 Conversion Rate shall forthwith be
                                 readjusted to such Conversion Rate as would
                                 have been obtained had an adjustment been
                                 made upon the issuance of such options,
                                 warrants, rights or such convertible or
                                 exchangeable securities on the basis of the
                                 issuance of only the number of shares of
                                 Common Stock actually issued upon the
                                 exercise of such options, warrants or
                                 rights, or upon the conversion or exchange
                                 of such convertible or exchangeable
                                 securities; and

                            (5)  if the Conversion Rate shall have been
                                 adjusted upon the issuance of any such
                                 options, warrants, rights or convertible or
                                 exchangeable securities, no further
                                 adjustment of the Conversion Rate shall be
                                 made for the actual issuance of Common Stock
                                 upon the exercise, conversion or exchange
                                 thereof;

                PROVIDED, HOWEVER, that no decrease in the Conversion Rate shall
                be made pursuant to subclauses (1) or (2) of this Section
                5(c)(ii)(C).

                (iii) OTHER DISTRIBUTIONS. In case the Corporation shall fix a
        record date for the making of a distribution to all holders of shares of
        its Common Stock (i) of shares of any class other than its Common Stock
        or (ii) of evidences of indebtedness of the Corporation or any
        subsidiary or (iii) of assets (including cash but excluding dividends or
        distributions referred to in subparagraph 5(c)(i) above), or (iv) of
        rights or warrants, in each case the Conversion Rate in effect
        immediately prior thereto shall be increased immediately thereafter to
        the rate determined


                                     -6-

<PAGE>

        by dividing the Liquidation Preference by the quotient obtained by
        dividing (1) an amount equal to the difference resulting from (A) the
        number of shares of Common Stock outstanding on such record date
        multiplied by the Liquidation Preference divided by the Conversion Rate
        on such record date, less (B) the fair market value (as determined by
        the Board, whose determination shall be conclusive) of said shares or
        evidences of indebtedness or assets or rights or warrants to be so
        distributed, by (2) the sum of the number of shares of Common Stock
        outstanding on such record date. Such adjustment shall be made
        successively whenever such a record date is fixed. In the event that
        such distribution is not so made, the Conversion Rate then in effect
        shall be readjusted, effective as of the date when the Board determines
        not to distribute such shares, evidences of indebtedness, assets, rights
        or warrants, as the case may be, to the Conversion Rate which would then
        be in effect if such record date had not been fixed.

                (iv) ROUNDING OF CALCULATIONS; MINIMUM ADJUSTMENT. All
        calculations under this subparagraph 5(c) shall be made to the nearest
        cent or to the nearest one hundredth (1/100th) of a share, as the case
        may be. Any provision of this Paragraph 5 to the contrary
        notwithstanding, no adjustment in the Conversion Rate shall be made if
        the amount of such adjustment would be less than 1% of the then current
        Conversion Rate; but any such amount shall be carried forward and an
        adjustment with respect thereto shall be made at the time of and
        together with any subsequent adjustment which, together with such amount
        and any other amount or amounts so carried forward, shall aggregate 1%
        or more.

                (v) TIMING OF ISSUANCE OF ADDITIONAL COMMON STOCK UPON
        CERTAIN ADJUSTMENTS. In any case in which the provisions of this
        subparagraph 5(c) shall require that an adjustment shall become
        effective immediately after a record date for an event, the
        Corporation may defer until the occurrence of such event (A) issuing
        to the holder of any share of the Series B Preferred Stock converted
        after such record date and before the occurrence of such event the
        additional shares of Common Stock issuable upon such conversion by
        reason of the adjustment required by such event over and above the
        shares of Common Stock issuable upon such conversion before giving
        effect to such adjustment and (B) paying to such holder any amount of
        cash in lieu of a fractional share of Common Stock pursuant to
        subparagraph 5(d); PROVIDED that the Corporation upon request shall
        deliver to such holder a due bill or other appropriate instrument
        evidencing such holder's right to receive such additional shares, and
        such cash, upon the occurrence of the event requiring such adjustment.

        (d) FRACTIONAL SHARES. No fractional shares of Common Stock or scrip
shall be issued upon conversion of shares of the Series B Preferred Stock. If
more than one share of the Series B Preferred Stock shall be surrendered for
conversion at any one time by the same holder, the number of full shares of
Common Stock issuable upon conversion thereof shall be computed on the basis of
the aggregate number of shares of the Series B Preferred Stock so surrendered.
Instead of any fractional shares of Common Stock which would otherwise be
issuable upon conversion of any shares of the Series B Preferred Stock, the
Corporation shall pay a cash adjustment in respect of such fractional interest
in an amount equal to that fractional interest of the then Current Market Price,
as defined in subparagraph 5(e) below.

        (e) CURRENT MARKET PRICE. The Current Market Price at any date shall
mean, in the event the Common Stock is publicly traded, the average of the daily
closing prices per share of Common Stock for twenty (20) consecutive trading
days ending three (3) trading days before such date (as adjusted for any stock
dividend, split, combination or reclassification that took effect during such 20
trading day period). The closing price for each day shall be the last reported
sale price regular way or, in case no such reported


                                     -7-

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

        (f) STATEMENT REGARDING ADJUSTMENTS. Whenever the Conversion Rate shall
be adjusted as provided in subparagraph 5(c), the Corporation shall forthwith
file, at the principal office of the Corporation, a statement showing in detail
the facts requiring such adjustment and the Conversion Rate that shall be in
effect after such adjustment, and the Corporation shall also cause a copy of
such statement to be sent by mail, first class postage prepaid, to each holder
of shares of the Series B Preferred Stock at its address appearing on the
Corporation's records. Each such statement shall be signed by the Corporation's
chief financial officer. Where appropriate, such copy may be given in advance
and may be included as part of a notice required to be mailed under the
provisions of subparagraph 5(g).

        (g) NOTICE TO HOLDERS. In the event the Corporation shall propose to
take any action of the type described in clause (i) (but only if the action of
the type described in clause (i) would result in an adjustment in the Conversion
Rate), (i) or (ii) of subparagraph 5(c), or described in subparagraph 5(k), the
Corporation shall give notice to each holder of shares of the Series B Preferred
Stock, in the manner set forth in subparagraph 5(g), which notice shall specify
the record date, if any, with respect to any such action and the approximate
date on which such action is to take place. Such notice shall also set forth
such facts with respect thereto as shall be reasonably necessary to indicate the
effect on the Conversion Rate and the number, kind or class of shares or other
securities or property which shall be deliverable upon conversion of shares of
the Series B Preferred Stock. In the case of any action which would require the
fixing of a record date, such notice shall be given at least ten (10) days prior
to the date so fixed, and in case of all other action, such notice shall be
given at least fifteen (15) days prior to the taking of such proposed action.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

        (h) MECHANICS OF CONVERSION. The holder of any shares of the Series B
Preferred Stock may exercise the conversion right specified in subparagraph 5(a)
by surrendering to the Corporation the certificate or certificates representing
the shares of the Series B Preferred Stock to be converted, accompanied by
written notice specifying the number of such shares to be converted. If the
certificate representing shares of Common Stock issuable upon conversion of
shares of the Series B Preferred Stock is to be issued in a name other than the
name on the face of the certificate representing such shares of the Series B
Preferred Stock, such certificate shall be accompanied by such evidence of the
assignment and such evidence of the signatory's authority with respect thereto
as deemed appropriate by the Corporation and such certificate shall be endorsed
directly or through stock powers to the Corporation or in blank. Conversion
shall be deemed to have been effected on the date when delivery of notice of an
election to convert pursuant to subparagraph 5(a) and of certificates
representing the shares being converted is made


                                     -8-

<PAGE>

(the "Conversion Date"). As promptly as practicable after the Conversion Date,
the Corporation shall issue and deliver to or upon the written order of such
holder a certificate or certificates for the number of full shares of Common
Stock to which such holder is entitled upon such conversion. The person in whose
name the certificate or certificates for Common Stock are to be issued shall be
deemed to have become a holder of record of such Common Stock on the applicable
Conversion Date. Upon conversion of only a portion of the number of shares
covered by a certificate representing shares of Series B Preferred Stock
surrendered for conversion, the Corporation shall issue and deliver to or upon
the written order of the holder of the certificate so surrendered for
conversion, at the expense of the Corporation, a new certificate representing
the number of shares of the Series B Preferred Stock representing the
unconverted portion of the certificate so surrendered. The Corporation shall pay
on any Conversion Date all accrued and unpaid dividends (including any accrued
but unpaid dividends thereon) to and including such date on all shares of Series
B Preferred Stock to be so converted.

        (i) TREASURY STOCK. For the purposes of this Paragraph 5, the sale or
other disposition of any Common Stock theretofore held in the Corporation's
treasury shall be deemed to be an issuance thereof.

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

        (k) CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE. In case of any
consolidation with or merger of the Corporation with or into another corporation
or other entity, or in case of any sale, lease or conveyance to another
corporation or other entity of the assets of the Corporation as an entirety or
substantially as an entirety, each share of the Series B Preferred Stock shall
after the date of such consolidation, merger, sale, lease or conveyance be
convertible into the number of shares of stock or other securities or property
(including cash) to which the Common Stock issuable (at the time of such
consolidation, merger, sale, lease or conveyance, as if the Series B Preferred
Stock were then optionally convertible or mandatorily convertible, as the case
may be) upon conversion of such share of the Series B Preferred Stock would have
been entitled upon such consolidation, merger, sale, lease or conveyance; and in
any such case, if necessary, the provisions set forth herein with respect to the
rights and interests thereafter of the holders of the shares of the Series B
Preferred Stock (including without limitation the definition of Current Market
Price) shall be appropriately adjusted so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or property thereafter
deliverable on the conversion of the shares of the Series B Preferred Stock.

6.      VOTING RIGHTS.

        So long as any shares of Series B Preferred Stock remain outstanding,
the Corporation shall not, without the affirmative consent or approval of the
holders of shares representing at least 50% of the voting power of the Series B
Preferred Stock then outstanding, acting separately as one class: (i) amend,
alter or repeal any of the provisions of this Certificate of Designation, (ii)
authorize or issue any Parity or Senior Stock; or (iii) make any Restricted
Payment.

7.      EXCLUSION OF OTHER RIGHTS.


                                     -9-

<PAGE>

        Except as may otherwise be required by law, the shares of Series B
Preferred Stock shall not have any voting rights, preferences or relative,
participating, optional or other special rights, other than those specifically
set forth in this resolution (as such resolution may be amended from time to
time) and in the Corporation's Certificate of Incorporation.

8.      HEADINGS OF SUBDIVISIONS.

        The headings of the various subdivisions hereof are for convenience of
reference only and shall not affect the interpretation of any of the provisions
hereof.

9.      SEVERABILITY OF PROVISIONS.

        If any right, preference or limitation of the Series B Preferred Stock
set forth in this resolution (as such resolution may be amended from time to
time) is invalid, unlawful or incapable of being enforced by reason of any rule
of law or public policy, all other rights, preferences and limitations set forth
in this resolution (as so amended) which can be given effect without the
invalid, unlawful or unenforceable right, preference or limitation shall,
nevertheless, remain in full force and effect, and no right, preference or
limitation herein set forth shall be deemed dependent upon any other such right,
preference or limitation unless so expressed herein.

10.     STATUS OF REACQUIRED SHARES.

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

         THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUED UPON ITS
                 EXERCISE ARE SUBJECT TO THE RESTRICTIONS ON
               TRANSFER SET FORTH IN SECTION 4 OF THIS WARRANT

Warrant No.                                            Number of Shares:
                                                       (subject to adjustment)
Date of Issuance:       May 17, 1993


                           FIRST SEISMIC CORPORATION

                         COMMON STOCK PURCHASE WARRANT

                           (Void after June 1, 2000)


        First Seismic Corporation, a Delaware corporation (the "Company"), for
value received, hereby certifies that           or his, her or its registered
assigns (the "Registered Holder"), is entitled, subject to the terms set
forth below, to purchase from the Company, at any time or from time to time
on or after the date of issuance and on or before June 1, 2000 at not later
than 5:00 p.m. (Houston, Texas time),         shares of Common Stock, $ .01 par
value per share, of the Company, at a purchase price of $.50 per share. The
shares purchasable upon exercise of this Warrant, and the purchase price per
share, each as adjusted from time to time pursuant to the provisions of this
Warrant, are hereinafter referred to as the "Warrant Shares" and the
"Purchase Price," respectively.

        1.      EXERCISE.

                (a) This Warrant may be exercised by the Registered Holder, in
whole or in part, by surrendering this Warrant, with the purchase form appended
hereto as EXHIBIT I duly executed by such Registered Holder or by such
Registered Holder's duly authorized attorney, at the principal office of the
Company, or at such other office or agency as the Company may designate,
accompanied by payment in full, in lawful money of the United States, of the
Purchase Price payable in respect of the number of Warrant Shares purchased upon
such exercise.

                (b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in subsection
1(a) above. At such time, the


<PAGE>

person or persons in whose name or names any certificates for Warrant Shares
shall be issuable upon such exercise as provided in subsection 1(d) below
shall be deemed to have become the holder or holders of record of the Warrant
Shares represented by such certificates.

                (c) As soon as practicable after the exercise of this Warrant in
full or in part, and in any event within 10 days thereafter, the Company, at its
expense, will cause to be issued in the name of, and delivered to, the
Registered Holder, or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct:

                    (i) a certificate or certificates for the number of full
Warrant Shares to which such Registered Holder shall be entitled upon such
exercise plus, in lieu of any fractional share to which such Registered Holder
would otherwise be entitled, cash in an amount determined pursuant to Section 3
hereof; and

                    (ii) in case such exercise is in part only, a new warrant
or warrants (dated the date hereof) of like tenor, calling in the aggregate
on the face or faces thereof for the number of Warrant Shares equal (without
giving effect to any adjustment therein) to the number of such shares called
for on the face of this Warrant minus the number of such shares purchased by
the Registered Holder upon such exercise.

        2.      ADJUSTMENTS.

                (a) If outstanding shares of the Company's Common Stock shall be
subdivided into a greater number of shares or a dividend in Common Stock shall
be paid in respect of Common Stock, the Purchase Price in effect immediately
prior to such subdivision or at the record date of such dividend shall
simultaneously with the effectiveness of such subdivision or immediately after
the record date of such dividend be proportionately reduced. If outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Purchase Price in effect immediately prior to such combination shall,
simultaneously with the effectiveness of such combination, be proportionately
increased. When any adjustment is required to be made in the Purchase Price, the
number of Warrant Shares purchasable upon the exercise of this Warrant shall be
changed to the number determined by dividing (i) an amount equal to the number
of shares issuable upon the exercise of this Warrant immediately prior to such
adjustment, multiplied by the Purchase Price in effect immediately prior to such
adjustment, by (ii) the Purchase Price in effect immediately after such
adjustment.


                                      -2-

<PAGE>


                (b) If there shall occur any capital reorganization or
reclassification of the Company's Common Stock (other than a change in par value
or a subdivision or combination as provided for in subsection 2(a) above), or
any consolidation or merger of the Company with or into another corporation, or
a transfer of all or substantially all of the assets of the Company, then, as
part of any such reorganization, reclassification, consolidation, merger or
sale, as the case may be, lawful provision shall be made so that the Registered
Holder of this Warrant shall have the right thereafter to receive upon the
exercise hereof the kind and amount of shares of stock or other securities or
property which such Registered Holder would have been entitled to receive if,
immediately prior to any such reorganization, reclassification, consolidation,
merger or sale, as the case may be, such Registered Holder had held the number
of shares of Common Stock which were then purchasable upon the exercise of this
Warrant. In any such case, appropriate adjustment (as reasonably determined in
good faith by the Board of Directors of the Company) shall be made in the
application of the provisions set forth herein with respect to the rights and
interests thereafter of the Registered Holder of this Warrant, such that the
provisions set forth in this Section 2 (including provisions with respect to
adjustment of the Purchase Price) shall thereafter be applicable, as nearly as
is reasonably practicable, in relation to any shares of stock or other
securities or property thereafter deliverable upon the exercise of this Warrant.

                (c) When any adjustment is required to be made in the Purchase
Price, the Company shall promptly mail to the Registered Holder a certificate
setting forth the Purchase Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Such certificate shall also
set forth the kind and amount of stock or other securities or property into
which this Warrant shall be exercisable following the occurrence of any of the
events specified in subsection 2(a) or (b) above.

        3.      FRACTIONAL SHARES. The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall make an
adjustment therefor in cash on the basis of the fair market value per share of
Common Stock, as determined by the Company's Board of Directors.

        4.      REQUIREMENTS FOR TRANSFER.

                (a) This Warrant and the Warrant Shares shall not be sold or
transferred unless either (i) they first shall have been registered under the
Securities Act of 1933, as amended (the "Act"), or (ii) the Company first shall
have been furnished with


                                      -3-

<PAGE>

an opinion of legal counsel, reasonably satisfactory to the Company, to the
effect that such sale or transfer is exempt from the registration
requirements of the Act.

                (b) Notwithstanding the foregoing, no registration or opinion of
counsel shall be required for (i) a transfer by a Registered Holder which is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner, if the transferee agrees in writing to be subject to
the terms of this Section 4, or, (ii) a transfer made in accordance with Rule
144 under the Act.

                (c) Each certificate representing Warrant Shares shall bear a
legend substantially in the following form:

                "The securities represented by this certificate have not been
                registered under the Securities Act of 1933, as amended, and may
                not be offered, sold or otherwise transferred, pledged or
                hypothecated unless and until such securities are registered
                under such Act or an opinion of counsel satisfactory to the
                Company is obtained to the effect that such registration is not
                required."

The foregoing legend shall be removed from the certificates representing any
Warrant Shares, at the request of the holder thereof, at such time as they
become eligible for resale pursuant to Rule 144(k) under the Act.

        5.      NO IMPAIRMENT. The Company will not, by amendment of its charter
or through reorganization, consolidation, merger, dissolution, sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against impairment.

        6.      LIQUIDATING DIVIDENDS. If the Company pays a dividend or makes a
distribution on the Common Stock payable otherwise than in cash out of earnings
or earned surplus (determined in accordance with generally accepted accounting
principles) except for a stock dividend payable in shares of Common Stock (a
"Liquidating Dividend"), then the Company will pay or distribute to the
Registered Holder of this Warrant, upon the exercise


                                      -4-

<PAGE>

hereof, in addition to the Warrant Shares purchased upon such exercise, the
Liquidating Dividend which would have been paid to such Registered Holder if
he had been the owner of record of such Warrant Shares immediately prior to
the date on which a record is taken for such Liquidating Dividend or, if no
record is taken, the date as of which the record holders of Common Stock
entitled to such dividends or distribution are to be determined.

        7.      NOTICES OF RECORD DATE, ETC. In case:

                (a) the Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time deliverable upon the exercise of
this Warrant) for the purpose of entitling or enabling them to receive any
dividend or other distribution, or to receive any right to subscribe for or
purchase any shares of stock of any class or any other securities, or to receive
any other right; or

                (b) of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the surviving entity), or any
transfer of all or substantially all of the assets of the Company; or

                (c) of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Registered Holder of this Warrant a notice specifying, as the case may be, (i)
the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or such other stock or securities at the
time deliverable upon the exercise of this Warrant) shall be entitled to
exchange their shares of Common Stock (or such other stock or securities) for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up. Such notice shall be mailed at least ten (10) days prior to the
record date or effective date for the event specified in such notice.

        8.      RESERVATION OF STOCK. The Company will at all times reserve and
keep available, solely for issuance and delivery upon


                                     -5-

<PAGE>

the exercise of this Warrant, such number of Warrant Shares and other stock,
securities and property, as from time to time shall be issuable upon the
exercise of this Warrant.

        9.      EXCHANGE OF WARRANTS. Upon the surrender by the Registered
Holder of any Warrant or Warrants, properly endorsed, to the Company at the
principal office of the Company, the Company will, subject to the provisions of
Section 4 hereof, issue and deliver to or upon the order of such Holder, at the
Company's expense, a new Warrant or Warrants of like tenor, in the name of such
Registered Holder or as such Registered Holder (upon payment by such Registered
Holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

        10.     REPLACEMENT OF WARRANTS. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to the Company, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will issue, in lieu thereof, a new
Warrant of like tenor.

        11.     TRANSFERS, ETC.

                (a) The Company will maintain a register containing the names
and addresses of the Registered Holders of this Warrant. Any Registered Holder
may change his, her or its address as shown on the warrant register by written
notice to the Company requesting such change.

                (b) Subject to the provisions of Section 4 hereof, this Warrant
and all rights hereunder are transferable, in whole or in part, upon surrender
of this Warrant with a properly executed assignment (in the form of EXHIBIT II
hereto) at the principal office of the Company.

                (c) Until any transfer of this Warrant is made in the warrant
register, the Company may treat the Registered Holder of this Warrant as the
absolute owner hereof for all purposes; PROVIDED, HOWEVER, that if and when this
Warrant is properly assigned in blank, the Company may (but shall not be
obligated to) treat the bearer hereof as the absolute owner hereof for all
purposes, notwithstanding any notice to the contrary.


                                     -6-

<PAGE>

        12.     MAILING OF NOTICES, ETC. All notices and other communications
from the Company to the Registered Holder of this Warrant shall be mailed by
first-class certified or registered mail, postage prepaid, to the address
furnished to the Company in writing by the last Registered Holder of this
Warrant who shall have furnished an address to the Company in writing. All
notices and other communications from the Registered Holder of this Warrant or
in connection herewith to the Company shall be mailed by first-class certified
or registered mail, postage prepaid, to the Company at its principal office set
forth below. If the Company should at any time change the location of its
principal office to a place other than as set forth below, it shall give prompt
written notice to the Registered Holder of this Warrant and thereafter all
references in this Warrant to the location of its principal office at the
particular time shall be as so specified in such notice.

        13.     NO RIGHTS AS STOCKHOLDER. Until the exercise of this Warrant,
the Registered Holder of this Warrant shall not have or exercise any rights by
virtue hereof as a stockholder of the Company.

        14.     CHANGE OR WAIVER. Any term of this Warrant may be changed or
waived only by an instrument in writing signed by the party against which
enforcement of the change or waiver is sought.

        15.     HEADINGS. The headings in this Warrant are for purposes of
reference only and shall not limit or otherwise affect the meaning of any
provision of this Warrant.

        16.     GOVERNING LAW. This Warrant will be governed by and construed in
accordance with the laws of the State of Texas.

                           (Void after October 15, 2005)

share. The shares purchasable upon exercise of this Warrant, and the purchase
price per share, each as adjusted from time to time pursuant to the
provisions of this Warrant, are hereinafter referred to as the "Warrant
Shares" and the "Purchase Price," respectively.

        1.      EXERCISE.

                (a) This Warrant may be exercised by the Registered Holder, in
whole or in part, by surrendering this Warrant, with the purchase form appended
hereto as EXHIBIT I duly executed by such Registered Holder or by such
Registered Holder's duly authorized attorney, at the principal office of the
Company, or at such other office or agency as the Company may designate,
accompanied by payment in full, in lawful money of the United States, of the
Purchase Price payable in respect of the number of Warrant Shares purchased upon
such exercise.

                (b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in subsection
1(a) above. At such time, the person or persons in whose name or names any
certificates for Warrant Shares shall be issued upon such exercise as provided
in subsection 1(d) below shall be deemed to have becomes the holder or holders
of record of the Warrant Shares represented by such certificates.

                (c) As soon as practicable after the exercise of this Warrant
in full or in part, and in any event within 10 days thereafter, the Company,
at its expense, will cause to be issued in the name of, and delivered to, the
Registered Holder, or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct:

                (i)     a certificate or certificates for the number of full
                        Warrant Shares to which such Registered Holder shall
                        be entitled upon such exercise plus, in lieu of any
                        fractional share to which such Registered Holder
                        would otherwise be entitled, cash in an amount
                        determined pursuant to Section 3 hereof; and


                                    Page 1

<PAGE>

                (ii)    in case such exercise is in part only, a new warrant
                        or warrants (dated the date hereof) of like tenor,
                        calling in the aggregate on the face or faces thereof
                        for the number of Warrant Shares equal (without
                        giving effect to any adjustment therein) to the
                        number of such shares called for on the face of this
                        Warrant minus the number of such shares purchased by
                        the Registered Holder upon such exercise.

        2.      ADJUSTMENTS.

                (a) If outstanding shares of the Company's Common Stock shall be
subdivided into a greater number of shares or a dividend in Common Stock shall
be paid in respect of Common Stock, the Purchase Price in effect immediately
prior to such subdivision or at the record date of such dividend shall
simultaneously with the effectiveness of such subdivision or immediately after
the record date of such dividend be proportionately reduced. If outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Purchase Price in effect immediately prior to such combination shall,
simultaneously with the effectiveness of such combination, be proportionately
increased. When any adjustment is required to be made in the Purchase Price, the
number of Warrant Shares purchasable upon the exercise of this Warrant shall be
changed to the number determined by dividing (1) an amount equal to the number
of shares issuable upon the exercise of this Warrant immediately prior to such
adjustment, multiplied by the Purchase Price in effect immediately prior to such
adjustment, by (ii) the Purchase Price in effect immediately after such
adjustment.

                (b) If there shall occur any capital reorganization or
reclassification of the Company's Common Stock (other than a change in par value
or a subdivision or combination as provided for in subsection 2(a) above), or
any consolidation or merger of the Company with or into another corporation, or
a transfer of all or substantially all of the assets of the Company, then, as
part of any such reorganization, reclassification, consolidation, merger or
sale, as the case may be, lawful provision shall be made so that the Registered
Holder of this Warrant shall have the right thereafter to receive upon the
exercise hereof the kind and amount of shares of stock or other securities or
property which such Registered Holder would have been entitled to receive if,
immediately prior to any such reorganization, reclassification, consolidation,
merger or sale, as the case may be, such Registered Holder had held the number
of shares of Common Stock which were then purchasable upon the exercise of this
Warrant. In any such case, appropriate adjustment (as reasonably determined in
good faith by the Board of Directors of the Company) shall be made in the
application of the provisions set forth herein with respect to the rights and
interests thereafter of the Registered Holder of this Warrant, such that the
provisions set forth in this Section 2 (including provisions with respect to
adjustment of the Purchase Price) shall thereafter be applicable, as nearly as
is reasonably practicable, in relation to any shares of stock or other
securities or property thereafter deliverable upon the exercise of this Warrant.

                (c) When any adjustment is required to be made in the Purchase
Price, the Company shall promptly mail to the Registered Holder a certificate
setting forth the Purchase Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Such certificate shall also
set forth the kind and amount of stock or other securities or property into
which this Warrant shall be exercisable following the occurrence of any of the
events specified in subsection 2(a) or (b) above,.

        3.      FRACTIONAL SHARES. The Company shall not be required upon the
exercise of this Warrant to issue any fractional shares, but shall make an
adjustment therefor in cash on the basis of the fair market value per share of
Common Stock, as determined by the Company's Board of Directors.

have been furnished with an opinion of legal counsel, reasonably satisfactory to
the Company, to the effect that such sale or transfer is exempt from the
registration requirements of the Act.

                (b) Notwithstanding the foregoing, no registration or opinion of
counsel shall be required for (i) a transfer by a Registered Holder which is a
partnership. to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such

the terms of this Section 4, or (ii) a transfer made in accordance with Rule 144
under the: Act.

                (c) Each certificate representing Warrant Shares shall bear a

                "The securities represented by this certificate have not been
                registered under the Securities Act of 1933, as amended, and may
                not be offered, sold or otherwise transferred, pledged or
                hypothecated unless and until such securities are registered
                under such Act or an opinion of counsel satisfactory to the
                Company is obtained to the effect that such registration is not
                required."

distribution are to be determined.

December 31, 1998 by and among First Seismic Corporation, a Texas Corporation
("First"), and the undersigned holders (the "Noteholders" and each individually
a "Noteholder") of the 6% Secured Promissory Notes issued by First on May 12,
1993 in the aggregate principal amount of $500,000 (the "Notes").

         1.       First desires to purchase from the Noteholders the Notes in
exchange for 977,508 shares of First's common stock ("Common Stock"), par value
$0.01 per share, (the "Shares") and the Noteholders desire to sell such Notes to
First.

         2.       The Notes were secured by First through a Stock Pledge
Agreement, executed in May 1993, by the Noteholders and the Chairman of First,
Rogers Beall (the `Pledge Agreement"), by which the Noteholders received a
collateral interest in all of the shares of common stock of First Exchange
Corporation, a Delaware corporation and wholly-owned subsidiary of First (the
"Security Interests").

         3.       In addition to the Notes and the Security Interests, the
Noteholders received Warrants (the "Warrants") to purchase 500,000 shares of
First's common stock at a strike price of $.50 per share which will expire June
1, 2000.

         4.       The transactions contemplated by this Agreement are
conditioned upon and subject to each Noteholder conveying the Notes to First and
canceling all Security Interests held by such Noteholder, the holders of an
aggregate of 80% of the Warrants (the "80% Holders") entering into an agreement
with First to exercise all of the outstanding Warrants held by such Holders and
exchange all such Warrants for additional warrants to purchase shares of common
stock of First (the "Warrant Agreement") and the closing of such agreement
concurrently with the closing of this Agreement.

         5.       The Noteholders are familiar with the business, financial
condition and prospects of First and acknowledge that in connection with the
transactions contemplated by this Agreement and the Warrant Agreement they have
been afforded the opportunity to review certain financial information regarding
First and to ask questions of and receive satisfactory answers from management
of First concerning the business, financial condition and prospects of First.

         In consideration of the premises and agreements contained herein, the

         existing, and in good standing under the laws of the jurisdictions in
         which it is incorporated and is duly qualified as a foreign corporation
         (or other legal entity) in all jurisdictions in which the nature of its

         qualification necessary, except where the failure to so qualify would
         not have a material adverse effect on the business

         condition or results of operations of First and its Subsidiaries, taken
         as a whole (a "Material Adverse Effect").

                  3.1.2    CORPORATE POWER AND AUTHORIZATION. First has the
         requisite corporate power and authority to execute, deliver, and
         perform its obligations under this Agreement and the Warrant Agreement,

         action on First's part, including approval of its Board of Directors,
         requisite for the due execution, delivery, and performance of this
         Agreement has been duly and effectively taken.

                  3.1.3    VALID ISSUANCE. The Shares have been duly and validly
         authorized for issuance by First and, when issued in accordance with
         the terms and conditions contained in this Agreement, the Shares will
         be duly authorized, validly issued, fully paid and nonassessable and
         will not be subject to any preemptive or similar rights.

         this Agreement nor the consummation of the transactions provided for
         herein or contemplated hereby nor the fulfillment by First of the terms
         hereof will (a) violate any provision of the Articles of Incorporation
         or the bylaws of First, (b) require any consent or approval (other than
         any consent or approval that has previously been obtained) under any of
         the terms, conditions or provisions of any governmental permit, note,
         bond, mortgage, indenture, loan, distribution agreement, license,
         agreement, lease, or instrument or obligation to which First is a party
         or by which First may be bound (except where the failure to obtain such
         consent or approval will not have a Material Adverse Effect), or (c)
         violate any law, judgment, order, writ, injunction, decree, statute,
         rule, or regulation of any foreign or domestic federal, state, county,
         municipal, or other governmental or regulatory authority, agency,
         board, body, commission, instrumentality, court, or any political

         subject, and required in connection with First's valid execution,
         delivery, or performance of this Agreement and the offer, sale, and
         delivery of the Shares and the consummation of any other transaction
         contemplated on the part of First have been obtained or made.

                  3.1.8    LITIGATION. Except as discussed in Schedule 3.1.8 or
         as described in any report delivered to the Noteholders, there is no
         action, suit, or proceeding, or any governmental investigation or any
         arbitration, in each case pending or, to the knowledge of First,
         threatened against First or any material property of First before any
         court or arbitrator or any governmental or administrative body, agency
         or official (i) which challenges the validity of this Agreement or the
         issuance of the Shares; or (ii) which, if adversely determined, would
         have a Material Adverse Effect.

                  3.1.9    FEES AND COMMISSIONS. Neither First nor, to the

         broker, agent, financial advisor, or other intermediary (collectively,
         an "Intermediary") in connection with the transactions contemplated by
         this Agreement. First has a regular investment banking agreement with
         Nicholas Rockecharlie, for future fundraising which does not cover the
         transactions contemplated by this Agreement.

         1,291,607 shares of Common Stock are or will be reserved for issuance

         closing of the new Warrant Agreements), all of which, when issued in
         accordance with the terms of such warrants and stock options, will be
         validly issued, fully paid, and non-assessable; (iii) 50,000 shares of
         Preferred Stock are issued and outstanding and 150,000 of Preferred
         Stock are reserved for issuance in connection with the Fortesa Merger,

         agreement will be validly issued, fully paid, and nonassessable; (iv)
         except as disclosed on Schedule 3.1.10 no shares of Common Stock are
         owned or held by or for the account of First or any of its
         Subsidiaries; (v) except as disclosed on Schedule 3.1.10 neither First
         nor any of its Subsidiaries has outstanding any stock or other
         securities convertible into or exchangeable for any shares of capital
         stock, any rights to subscribe for or to purchase or any options for
         the purchase of or any agreements providing for the issuance
         (contingent or otherwise) of, or any calls, commitments or claims of
         any other character relating to the issuance of any capital stock, or
         any stock or securities convertible into or exchangeable for any
         capital stock which have not been waived (other than as contemplated by
         this Agreement); and (vi) except as disclosed on Schedule 3.1.10,
         neither First nor any of its Subsidiaries is subject to any obligation
         (contingent or otherwise) to repurchase or otherwise acquire or retire
         any shares of capital stock.

         3.2      REPRESENTATIONS AND WARRANTIES OF NOTEHOLDER. To induce First
to enter into this Agreement, each Noteholder represents and warrants to First
that:

                  3.2.1    PURCHASE FOR INVESTMENT.

                  (a)      Each Noteholder is acquiring the Shares for its own
         account and not with a view to the public resale or distribution of all
         or any part thereof in any transaction which would constitute a
         "distribution" within the meaning of the Securities Act.


                                       5

                  (b)      Each Noteholder acknowledges that the shares of
         Common Stock issuable by First under this Agreement have not been
         registered under the Securities Act and may not be sold or otherwise
         transferred unless (i) pursuant to an effective registration statement
         under the Securities Act or (ii) pursuant to an available exemption
         from registration under, or otherwise in compliance with the Securities
         Act. Each Noteholder acknowledges and agrees that in the case of a
         transfer or other disposition pursuant to clause (ii) above, such
         Noteholder shall be required to provide to First an opinion of counsel
         satisfactory to First to the effect that registration under the
         Securities Act is not required.

                  (c)      Each Noteholder is an "accredited investor" within
         the meaning of Rule 501 under Regulation D promulgated under the
         Securities Act, is experienced in evaluating investments in companies
         such as First, has such knowledge and experience in financial and
         business matters as to be capable of evaluating the merits and risks of
         its investment and has the ability to bear the entire economic risk of
         its investment. Each Noteholder has made its own evaluation of its sale
         of the Notes and First's issuance of Shares as contemplated by this
         Agreement, based upon such information as is available to it and
         without reliance upon First or any other person or entity, and each
         Noteholder agrees that neither First nor any other person or entity has
         any obligation to furnish any additional information to the Noteholders
         except as expressly set forth herein.

                  (d)      Each Noteholder acknowledges that the Shares may not
         be sold, transferred, pledged, hypothecated, or otherwise disposed of
         without registration under the Securities Act or an exemption
         therefrom, and that in the absence of an effective registration
         statement covering the Shares, issuable upon conversion of the Note, or
         an available exemption from registration under the Securities Act, the
         Shares must be held indefinitely.

                  (e)      Each Noteholder agrees that stock certificates issued
         as part of the Consideration shall bear legends in substantially the
         following form:

                  "THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
                  INVESTMENT AND MAY NOT BE SOLD OR OFFERED FOR SALE OR
                  OTHERWISE TRANSFERRED, EXCEPT PURSUANT TO (i) AN EFFECTIVE
                  REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (ii) AN
                  APPLICABLE EXEMPTION FROM REGISTRATION TINDER THE SECURITIES
                  ACT. ANY SALE PURSUANT TO CLAUSE (ii) OF THE PRECEDING
                  SENTENCE MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL
                  REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH
                  EXEMPTION FROM REGISTRATION IS AVAILABLE IN CONNECTION WITH
                  SUCH SALE."

                  3.2.2    AUTHORIZATION; NO CONFLICT. The Noteholders have all
         requisite power and authority to enter into this Agreement and to carry
         out and perform their obligations under


                                       6

<PAGE>

         the terms of this Agreement. This Agreement is a legal, valid, and
         binding obligation of the Noteholders. The execution, delivery, and
         performance of this Agreement by the Noteholders and the consummation
         by the Noteholders of the transactions contemplated hereby will not
         conflict with or result in a default under the terms of any material
         contract, agreement, obligation, commitment, or organizational document
         applicable to any Noteholder.

                  3.2.3    OWNERSHIP OF NOTE. Each Noteholder is the sole owner
         and holder of the Notes which such Noteholder will sell to First. There
         is no adverse claim against each Noteholder's interest in the Notes;
         nor is there any person who should claim to be a "bona fide purchaser"
         of the Notes other than Noteholder.

                                   ARTICLE 1V

                              REGISTRATION RIGHTS

         4.1      PIGGY-BACK REGISTRATION RIGHTS. First covenants and agrees
with the Noteholder, that, in the event First proposes to file a registration
statement under the Securities Act with respect to a firm commitment offering of
Common Stock (other than in connection with an exchange offer or a registration
statement on Form S-4 or S-8 or other similar registration statements not
available to register securities included), First shall in each case give
written notice of such proposed filing to the Noteholders at least 30 days
before the earlier of the anticipated or the actual effective date of the
registration statement and at least ten days before the initial filing of such
registration statement and such notice shall offer to such holders the
opportunity to include in such registration statement such number of shares of
Common Stock issued pursuant to this Agreement (the `Piggy-back Securities") as
they may request. Those Noteholders desiring inclusion of Piggy-back Securities
in such registration statement shall so inform First by written notice, given
within ten days of the giving of such notice by First in accordance with the
provisions of this Section 4.1. First shall permit, or shall cause the managing
underwriter of a proposed offering to permit, the holders of Piggy-back
Securities requested to be included in the registration to include such
securities in the proposed offering on the same terms and conditions as
applicable to securities of First. Notwithstanding the foregoing, if any such
managing underwriter shall advise First in writing that, in its opinion, the
distribution of all or a portion of the Piggy-back Securities requested to be
included in the registration concurrently with the securities being registered
by First would adversely affect the distribution of such securities by First for
its own account, then, provided that if any other securities are included in
such registration statement for the account of any person other than First and
the holders of Piggy-back Securities, such securities, including the Piggy-back
Securities, so included shall be apportioned among holders who wish to be
included therein pro rata according to amounts so requested to be included by
each such person. No such delay shall in any event impair any right granted
hereunder to make subsequent requests for inclusion pursuant to the terms of
this Agreement. All expenses of such registration shall be borne by First,
except that underwriting commissions and expenses attributable to the Piggy-back
Securities and fees and distributions of counsel and other advisors (if any) to
the holders requesting that the Piggy-back Securities be offered will be borne
by such holders.

Filed 1997

         Case No. 97CV981 BU(W); EAST TEXAS DATA, LLC AND CAPMAC EIGHTY-TWO
LIMITED PARTNERSHIP V. SEITEL DATA, INC. AND FIRST SEISMIC CORPORATION, In the
United States District Court, Northern District of Oklahoma.

         This case involves suit by minority partners of the previous owners of
First Seismic's East Texas data library for 7 1/2% of proceeds of use of that
seismic data acquired by First Seismic in 1989 from the majority partners,
Freeport-McMoran and SantaFe Energy. This data was re-sold by First Seismic to
Seitel in 1994, with revenue interests therefrom pledged to the 12% Senior
Noteholders of First Seismic. First Seismic was indemnified by Freeport-McMoran
and SantaFe Energy when data was initially acquired by First Seismic against the
plaintiffs. First Seismic has subsequently indemnified Seitel, but Seitel has
still held up payment of approximately $70,000 which corresponds to two (2)
years of First Seismic's revenue interest proceeds, pending the outcome of the
suit.

                           LOAN MODIFICATION AGREEMENT



The parties to this loan modification agreement ("AGREEMENT") dated and
effective as of October 1, 1997 (the "MODIFICATION DATE") are FIRST SEISMIC
C0RP0RATI0N, a Delaware corporation (the "COMPANY"), and C. H. Fitzpatrick, an
individual (the "SENIOR NOTE HOLDER"). For good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties agree as
follows:

        1.      BACKGROUND. The Senior Note Holder owns a 12% Senior Note due
December 31, 1996 made by the Company payable to the order of the Senior Note
Holder in the original principal face amount of $100,000.00, which promissory
note is, as it may have been renewed, extended, amended, or supplemented by one
or more documents, if any, dated before the Modification Date, herein called the
"NOTE"; and the Note as modified by this Agreement is herein called the
"MODIFIED NOTE." The Note was purchased by the Senior Note Holder pursuant to
the terms of a Note Purchase Agreement dated as of July 12, 1991 (the "NOTE
PURCHASE AGREEMENT"). The security for payment of the Note includes (without
limitation): a pro rata share in certain assets of the Company pledged pursuant
to that certain Security Agreement dated as of October 1, 1997, executed by the
Company as grantor (herein sometimes called "GRANTOR") in favor of Robert W.
Scharar, as agent for the Senior Secured Note Holders (defined below), which
Security Agreement is, as it may have been renewed, extended, amended, or
supplemented by one or more documents, if any, dated before the Modification
Date, herein called the "COLLATERAL DOCUMENT", reference being here made to the
Collateral Document and the recording thereof for all purposes. The Collateral
Document pledges certain personal property and revenue streams from general
intangible property of the Company (the "PROPERTY") therein described as
security for each holder of a 12% Senior Note due December 31, 1996, issued by
the Company (collectively, the "SENIOR SECURED NOTE HOLDERS") on a pro rata
basis.

In September 1992, the Company entered into an arrangement that modified the
Note in a manner mutually acceptable to the Company and the Senior Note Holder
and the notes of the other Senior Secured Note Holders (the "1992
MODIFICATION"). Pursuant to the 1992 Modification, the Company issued a total of
42,992 shares of common stock to the Senior Secured Note Holders on a pro rata
basis. Additionally, the Company executed the Collateral Document for purposes
of pledging the Property for the benefit of the Senior Secured Note Holders.

The Company has not paid any interest accruing on the Note since September 30,
1993. Interest accrued at a per annum rate of 12% from the date the Note was
issued and such accrued interest has been paid by the Company through September
30, 1993.

The Note, the Note Purchase Agreement, the Collateral Document, this Agreement,
and any other document now or hereafter securing, guaranteeing or executed in
connection with the loan evidenced by the Note, as such documents may have been
or may be herein or hereafter renewed, extended,


<PAGE>

amended or supplemented, are herein together called the "LOAN DOCUMENTS". The
Senior Note Holder is entitled to the benefits of the Loan Documents.

        2.      MODIFICATION: PRINCIPAL BALANCE OF THE NOTE. The Company and the
Senior Note Holder agree to extend the stated final maturity date of the Note
and to make certain other changes, as specified below in this Agreement. The
unpaid outstanding principal balance of the Note as of the Modification Date is
$58,078.54.

The Modified Note remains the obligation of the Company as borrower thereunder.
All provisions of the Note and the other Loan Documents remain in full force and
effect as therein written, except as expressly modified by this Agreement. To
the extent of any conflict between the Note (or any earlier modification of it)
and this Agreement, this Agreement shall control.

        3.      WAIVER AND SUSPENSION OF INTEREST. On and after the Modification
Date the unpaid principal balance of the Modified Note from day to day
outstanding shall bear no interest. The Senior Note Holder hereby waives any and
all demand and claim for any interest accrued and unpaid with respect to the
Note prior to the Modification Date. As of the Modification Date, the Company
shall no longer be liable for any interest on either the Note or the Modified
Note.

        4.      PAYMENT SCHEDULE AND MATURITY DATE. The maturity date of the
Modified Note is hereby extended to September 30, 1999. The Company promises to
satisfy its obligations under the Modified Note on or before September 30, 1999
through one of the following four options, which option shall be exercised in
the sole discretion of the Company:

                A. The Company may issue common stock in exchange for the then
        outstanding principal balance of the Modified Note valued at the average
        ask price of such common stock in an amount equal to such principal
        balance. The average ask price shall be established by taking the
        average of the public market trading price (if any) for such stock for a
        period of five (5) business days prior to the proposed exchange; or

                B. The Company may issue common stock in exchange for the then
        outstanding principal balance of the Modified Note valued at a stock
        price per share that is derived from a significant private placement of
        equity of the Company in an amount equal to such principal balance. The
        exchange hereunder shall be accomplished within forty-five (45) days of
        such significant private placement; or

                C. The Company may issue common stock in exchange for the then
        outstanding principal balance of the Modified Note valued at two times
        the actual net book value of the Company's equity per share, as such
        equity per share is determined

PAGE 2


<PAGE>

        in the most recent quarterly financial statements of the Company
        immediately prior to such exchange; or

                D. The Company may (i) pay the then outstanding principal
        balance of the Modified Note in cash in an amount equal to the full
        outstanding principal balance thereof or (ii) satisfy the Modified Note
        by a payment in cash in an amount equal to a portion of the then
        outstanding principal balance thereof together with the issuance of the
        Company's common stock (valued as set forth in either of A, B, or C
        above as determined by the Company) in an amount equal to the remaining
        portion of such principal balance after the application of the cash
        payment described in this Section D.

        5.      CERTAIN REPRESENTATIONS AND WARRANTIES. The Company hereby
represents and warrants to the Senior Note Holder that (a) it has full power and
authority to execute and deliver this Agreement and to incur and to perform the
obligations provided for herein; (b) the execution, delivery and performance of

subject; (c) the execution, delivery and performance of this Agreement have been

standing, under Texas law; (e) this Agreement and the other Loan Documents to
which the Company is a party constitute valid and legally binding obligations of
the Company enforceable in accordance with their terms.

the sole owner of the Property.

The Senior Note Holder hereby represents and warrants to the Company that it is
the sole owner of the Modified Note and that there is no adverse claim against
the Modified Note nor is there any person who could claim to be a bona fide
purchaser of the Modified Note, other than the Senior Note Holder.

        6.      LIENS. By this Agreement, all liens, security interests,
assignments, superior titles, rights, remedies, powers, equities and priorities
securing the Note (collectively, the "LIENS"), under the Collateral Document,
are hereby ratified and confirmed as valid, subsisting and continuing to secure
the Modified Note. Nothing in this Agreement shall in any manner diminish,
impair or extinguish any of the Liens or the Loan Documents or the principal
balance of the debt evidenced by the Note or be construed as a novation in any
respect. The Liens are not waived.

                               FARMOUT AGREEMENT
                        THIES BLOCK, REPUBLIC OF SENEGAL
- - --------------------------------------------------------------------------------

        THIS AGREEMENT is made and entered into effective December 17, 1997, by
and among each of Societe des Petroles du Senegal ("Petrosen"), the national oil
and gas company of the Republic of Senegal ("Senegal"), Benton Oil and Gas
Company ("Benton"), a Delaware USA corporation (or its designated affiliate),
and Fortesa Corporation ("Fortesa"), a Texas USA corporation (or its designated
affiliate).

        Petrosen is a party to a Convention (the "Convention") issued by the
Government of Senegal, dated effective February 26, 1993, granted by the Decree
No. 93-155 of February 26, 1993, regarding the exploration, development and
production of oil and/or gas from the Thies Block (the "Block"), which covers
certain lands onshore in Senegal as described therein.

        In consideration of the mutual benefits to be derived by each of them,
the parties to this Agreement (collectively, the "Parties," and individually, a
"Party") agree to the following terms and provisions regarding their acquisition
of their respective interests in the Block:

1.      ONSHORE WORK PROGRAM. Benton and Fortesa (collectively, the "Benton
Group") shall conduct, over the twenty-four (24) month period commencing on
February 26, 1998, the following operations (collectively, the "Onshore Work
Program") on the Thies Block:

        i.      The drilling, testing and (if warranted) completion of two
        additional wells on the Thies Block at locations selected by the
        Benton Group. The Benton Group shall have the right to produce and
        market the production from all existing and future productive wells
        on the Thies Block;

        ii.     The construction of a 4 1/2" or larger diameter pipeline from
        the Gadiaga No. 2 well, and other wells subsequently located near it
        to the vicinity of the Diam Niadio field;

        iii.    The evaluation and, if necessary, reprocessing of existing
        geophysical data covering the Block and the acquisition, if necessary
        of additional new geophysical data for the development of new
        drilling prospects on the Block.

        In case of the non-completion of the Onshore Work Program within the
twenty-four month period contemplated above, Petrosen agrees to join with the
Benton Group in seeking a one year extension to the exploration period which
begins on or about February 26, 1998, under the Convention.

        The Onshore Work Program shall include a budget of not less than
$5,400,000 to be expended by the Benton Group, after the expenditure of which
the Benton Group may elect to terminate their participation in the exploration
and development of the Block. With satisfactory initial results, the Benton
Group may spend an additional $5,400,000 on the Block.

2.      OWNERSHIP SHARES. The ownership of the Block, the obligation to bear
expenses (except as otherwise provided below in this Section), and the
allocation of revenues from the sale of production from the Block shall be in
the following shares:

                Petrosen        30%
                Benton          45%
                Fortesa         15%
                Third party     10%


<PAGE>


        The interest of Petrosen will be free of the obligation to bear any
expense (I.E. will be "carried") until the Benton Group has expended an
aggregate of $10,800,000 in the exploration and development of the Thies Block.
After the Benton Group has expended the sum of $10,800,000, Petrosen shall join
in bearing its share of all costs and expenses of conducting further operations
on the Block. All owners of the Block shall bear their respective shares of the
applicable royalty and other fiscal obligations imposed by the Convention and
shall pay their respective shares of all income taxes attributable to the
production and sale of hydrocarbons.

        Except for the carried interest of Petrosen, all owners of the Block
shall bear their respective shares of all costs and expenses of conducting
operations on the Block.

        In the event that any owner of the Block fails to bear its share of the
expenses of the Onshore Work Program, its ownership interest shall be allocated
to the Benton Group, unless otherwise agreed among the Parties.

        Except for the fiscal obligations imposed by the Convention, including
the royalty payable to Senegal, there are no other burdens measured by or
payable out of production.

3.      JOINT OPERATING AGREEMENT. The owners of the Block shall enter into a
mutually acceptable form of joint operating agreement, based upon the statutory
model form of joint operating agreement included in the petroleum legislation of
Senegal, governing operations on the Thies Block. The Parties shall negotiate
and conclude such agreement prior to the commencement of operations on the
Onshore Work Program. Benton shall be the initial operator designated under the
joint operating agreement.

4.      GAS DISPOSITION PROJECTS. The Benton Group shall have the right, but
not the obligation, to participate as to the same shares set forth in
Section 2, above, in any project facilities concerning the disposition or
utilization of any natural gas produced from the Thies Block. In the event
that any other party elects not to participate in any such project, the
Parties shall have the right to acquire their pro rata shares of any such
unclaimed interest. In addition, any equity funding of any such project
facilities provided by the Benton Group shall be credited against the
$10,800,000 carry provided for above.

5.      MISCELLANEOUS.

        mean US dollars.

the obligations of the Borrower under this Note to repay the outstanding
principal amount of the advances together with all accrued, unpaid interest

agreement, the Employer is not completely restructured and funded to perform
all of the obligations anticipated by the transition of Employer from a
seismic brokerage company to an independent oil company. The Employer seeks
to rely on Employee's leadership to develop and promote the acquisition of the
Company's asset base in this regard. The Employer will adopt a qualified 401K
plan for the benefit of all employees, including Employee, as soon as

endeavors anticipated herein

        7.      TERMINATION.

                (a) DEATH. If the Employee dies during the term of this
Agreement and while in the employ of Employer, this Agreement shall
automatically terminate and the Employer shall have no further obligation to
the Employee or his estate or heirs except for salary, earned vacation and
other benefits owed to the Employee. Subject to the Employee's insurability
on reasonable financial terms, the Employer shall pay for and obtain term
life insurance on the life of Employee in such amount and upon such terms as
is mutually agreeable to the Employer and Employee. Employee and Employer
equally shall have the right to name the beneficiaries of such life insurance
policy, as it is anticipated that this policy will be a key man policy having
death benefits to be shared equally by the Employee's heirs and the Employer.
This provision regarding the death of Employee controls in the event of
Employee's death and in the event that any other provisions or agreements
conflict with this provision.

                (b) DISABILITY. If during the term of this Agreement, the
Employee shall be prevented from performing his duties hereunder by reason of
disability, then the Employer, on ninety (90) days' prior notice to the
Employee, may terminate this Agreement. For purposes of this Agreement, the
Employee shall be deemed to have become disabled when the Board of Directors,
upon medical advice, shall have determined that the Employee has become
physically or mentally incapable (excluding infrequent and temporary absences
due to ordinary illness) of performing his duties under this Agreement. In
making any determination of disability pursuant to this paragraph (b), the
Board of Directors shall act upon the mutual advice of two qualified
physicians, one of whom

<PAGE>

shall be designated by the Employee and one of whom shall be designated by
the Employer. If such physicians are unable to agree as to the physical or
mental capacity of the Employee, such physicians shall designate a third
physician who, as an expert and not as an arbitrator, shall advise the Board
of Directors in such regard and whose determination in that matter shall be
conclusive and binding on the parties hereto. In the event of a termination
pursuant to this paragraph (b), the Employer shall be relieved of all its
obligations under this Agreement, except that the Employer shall pay to the
Employee or his estate in the event of his subsequent death, the Employee's
salary and benefits through the end of the 90-day period following the month
during which such disability was conclusively determined, plus accrued
vacation pay, if any. All such payments to the Employee or his estate shall
be made in the same manner and at the same times as the Employee's salary
would have been paid to the Employee had he not become disabled.

                (c) CERTAIN DISCHARGES. Prior to the end of the term of this
Agreement, the Employer may discharge the Employee for cause and terminate
this Agreement without any further liability hereunder to the Employee or his
estate, except the obligation of the Employer to pay the Employee's minimum
base salary including prorate of the 4O% bonus amount due to the date of
discharge. For purposes of this Agreement, a "discharge for cause" shall mean
a discharge resulting from a determination by the CEO and Board of Directors
that the Employee (i) has been convicted of a crime involving moral
turpitude, (ii) has regularly and willfully failed or refused to follow
written policies or directives established by the Board, (iii) has willfully
and persistently failed to attend to his duties, (iv) has committed acts
amounting to gross negligence or willful misconduct to the detriment of the
Employer or its affiliates. If the Employee shall be discharged by the
Employer for any reason other than those enumerated in this paragraph (c),
such discharge shall be deemed a "discharge without cause." In the event of a
discharge without cause or death (a), the Employer shall continue to pay the
Employee's base salary for the term of the contract and agrees to make all
payments for Employee for health insurance for Employee as were being paid by
or for the Employee upon the same terms as of the day preceding his
termination, said payments to be made under COBRA for the maximum period of
time allowed by COBRA. Further, any termination except for those enumerated
in this paragraph (c), any vesting stipulations for any compensation
contemplated herein or by subsequent agreement shall be determined as fully
vested as of the date of discharge. In the event of the Employer's insolvency
or inability at that time of being able to pay the termination costs accruing
to Employee of such event as herein specified, the Employers shall have the
option of settling any amounts still due to the Employee in common Stock at
the same per share price value as the Employers settlement of the 12% Senior
Noteholders April 1999 stock issuance.

                (d) TERMINATION BY THE EMPLOYEE. Prior to the end of the term
of this Agreement, the Employee, at his option, may terminate this Agreement
upon (i) a substantial breach by the Employer of its obligations under this
Agreement or (ii) sixty (60) days prior written notice. In the event of
termination pursuant to this paragraph (d), the Employer shall be relieved of
all of its obligations under this Agreement, except that the Employer shall
pay to the Employee the Employee's salary until the date of termination, plus
accrued vacation pay, if any.

                (e) CLOSE OF BUSINESS. Other than for insolvency as provided
above, should the business activities of Employer change and the Employee is
notified of discharge due to the close of business, merger, acquisition,
restructuring or other means prior to the end of this contract, Employee

<PAGE>

XXXXXXXXXXXXXX compensation and bonuses earned for the remaining term of the
contract, all vesting conditions pertaining to any issuance or vesting
requirement of any shares of stock or stock options shall be considered as
being fully vested. Further, the Employee shall be provided medical and life
insurance coverage for a maximum period of one year from such termination or
discharge by Employer. The Employer has the right to assign this agreement to
a successor Entity, in the event of the above business conditions, for
continuation of the employment of Employee under the same duties by such
successor entity.

the course of his employment by the Employer he will receive certain trade
secrets, lists of customers and other confidential information and knowledge
concerning the business of the Employer which the Employer desires to
protect. The Employee understands that such information and knowledge is
confidential and he agrees not to reveal such information and knowledge to
anyone outside the Employer so long as the confidential or secret nature
thereof shall continue. The Employee further agrees during the term of this
agreement or immediately thereafter that he will at no time use any of such
information or knowledge in competing with the Employer on an opportunity,
acreage, or an arrangement that the Employer had under consideration or
agreement during the term of Employment of Employee. Upon termination of this
Agreement, the Employee shall surrender to the Employer all papers,
documents, writings and other property produced by his or coming into his
possession by or through his employment or relating to any such information
or knowledge and the Employee agrees that all such materials will at all
times remain the property of the Employer.

        9.      INDEMNIFICATION. Employee shall be indemnified and held
harmless by Employer from all claims, suits or causes of action brought or
asserted against Employee arising from his position as an officer, director,
employee or representative of Employer or from acts which he performs in good
faith on behalf of Employer, including, but not limited, payment of legal
expenses arising from the defense of such claims, suits or causes of action.

be inadequate, agrees that the Employer shall be entitled to specific

         The purpose of this Directors' Stock Option Plan (the "Plan") is to
assist First Seismic Corporation in attracting, motivating and retaining
qualified non-employee directors by providing means whereby such persons will
be given an opportunity to acquire a proprietary interest in the Company's
future growth by purchasing shares of Common Stock.

2.       DEFINITIONS.

         When used in this Plan, unless the context otherwise requires:

NASDAQ National Market System or is listed on a national stock exchange, the
officially-quoted closing price on NASDAQ or such exchange, as the case may
be, on the date in question. In the event the Common Stock is not traded
publicly or such price information is not readily available, the Fair Market
Value of a share of Common Stock on any date shall be determined, in good
faith, by the Board or the Committee after such consultation with outside
experts as the Board or the Committee may deem advisable, and the Board or
the Committee shall maintain a written record of its method of determining

authority to construe, interpret and administer the Plan and to make
determinations which shall be final, conclusive and binding upon all persons,

the terms and provisions thereof, shall be as determined from time to time by
the Board of Directors or the Committee and each Option issued may

         (a) Except in the event of death, in which case they may be
exercised in full immediately, and except as provided in Section 12 below,
Directors' Options may be exercised only as follows: Options to purchase 50%
of the Shares may be exercised at any time from the date of grant; and
Options to purchase all of the shares subject to the Option may be exercised
after 12 months from the date of grant; PROVIDED, HOWEVER, that, in the event

notice in writing to such effect, together with the full purchase price.
Payment of the purchase price shall be made in cash or outstanding Common
Stock of the Company already owned by the optionee (valued at fair market
value). Option Agreements under the Plan may contain a provision to the
effect that all Federal and state taxes required to be withheld or collected
from an Optionee upon exercise of an Option may be satisfied by the

director, the Option of such holder shall terminate, except that, subject to
the limitation stated in the last sentence of this Section 11, (i) if his
director's status with the Company is terminated for any reason other than
his death, he may at any time within three (3) months after such termination
exercise his Option but only to the extent that it was exercisable by him on
the date of termination and only if his status was not terminated because of
a violation of his normal duties; and (ii) if he dies while serving as a
director of the Company, or within three (3) months after termination of such
status, his Option may be exercised by the person or persons to whom his
rights under the Option shall pass by will or by the laws of descent and
distribution, without regard to the vesting provisions included in the
Option. In no event may an Option be exercised to any extent by anyone after
the expiration of its term.

12.      CHANGES IN CAPITALIZATION: SPLITS, LIQUIDATIONS, MERGERS AND
         REORGANIZATIONS.

         (a) The aggregate number of shares of Common Stock for which Options
may be granted to eligible persons under the Plan, the number of shares of
Common Stock covered by each outstanding Option and the price per share
thereof in each such Option may be proportionately adjusted by the Board of
Directors or the Committee for any increase or decrease in the number of
issued shares of Common Stock of the Company resulting from a stock split, a
reverse stock split, a subdivision or consolidation of shares or other
similar capital adjustment, the payment of a stock dividend or any other
increase or decrease in such shares effected without receipt of consideration
by the Company. Any such determination by the Board of Directors of the
Company shall be conclusive.

         (b) On the day following the dissolution or liquidation of the
Company or upon any reorganization, merger, consolidation pursuant to which
the Company does not survive (except for a reincorporation of the Company in
another state), or sale of all or substantially all of the assets of the
Company or upon a change in the composition of the Board of Directors (not
approved by a majority of the directors in office at the time of such change)
which results in a change in "control" of the Company (for purposes of this
subsection "control" is defined as in the Employee Stock Option Plan of the
Company) each outstanding Option shall terminate; provided that in such event
each outstanding unexercised Option shall become fully vested under the Plan
and shall be immediately exercisable as of thirty (30) days prior to the
effective date of such dissolution, liquidation, reorganization, merger,
consolidation, sale of assets or change in control, and each Optionee may
exercise, in whole or in part, any unexpired Option or Options held for at
least six (6) months at the time of exercise. The grant of an Option under
the Plan shall have no effect on the ability of the Company to change or
adjust its capital structure or to merge, consolidate, dissolve, liquidate or
to sell or transfer all or any part of its business or assets.

13.      ISSUANCE OF SHARES AND COMPLIANCE WITH SECURITIES ACT.

         The Company may postpone the issuance and delivery of Shares upon
any exercise of an Option until (a) the admission of such Shares to listing
on any stock exchange on which Shares of the Company of the same class are
then listed and (b) the completion of such registration or other
qualification of such Shares under any state or Federal law, rule or
regulation as the Company shall determine to be necessary or advisable. Any
person exercising an Option shall make such representations and furnish such
information as may, in the opinion of counsel for the Company, be appropriate
to permit the Company to issue the Shares in compliance with the provisions
of the Securities Act of 1933, as amended.

14.      AMENDMENT AND TERMINATION OF THE PLAN.

         (a) Except as hereinafter provided, the Board of Directors or the
Committee may at any time withdraw or from time to time amend the Plan and
the terms and conditions of any Options not theretofore issued, and the Board
of Directors or the Committee, with the consent of the affected holder of an
Option, may at any time amend the terms and conditions of such Options as
have been theretofore granted. Notwithstanding the foregoing, any amendment
to the Plan by the Board of Directors or Committee which would (i) increase
the number of Shares issuable under Options, (ii) change the class of persons
to whom Options may be granted or (iii) change in any material respect the
limitations or provisions pertaining to Options, shall be subject to the
approval of the holders of a majority of the shares of the Company present at
any meeting of stockholders and entitled to vote thereat either prior to or
within one year after such amendment.

         (b) The determination of the Board of Directors or the Committee as
to any questions which may arise with respect to the interpretation of the
provisions of the Plan and Options granted hereunder shall be final and
conclusive.

         (c) The Board of Directors or the Committee may authorize and
establish such rules, regulations and revisions thereof, not inconsistent
with the provisions of the Plan, as it may deem advisable to make the Plan
and Options effective or provide for their administration, and may take such
other action with regard to the Plan and Options as it shall deem desirable
to effectuate their purpose.

         (d) The Plan shall remain in effect until such time as it is
terminated by the Board of Directors of the Company. No such termination
shall affect Options granted prior thereto.

15.      EFFECTIVE DATE OF THE PLAN.

EXHIBIT 10.6
                             FIRST SEISMIC CORPORATION

                            EMPLOYEES' STOCK OPTION PLAN

I.       PURPOSE

         The Employees' Stock Option Plan ("Plan") provides for the grant of
Stock Options, Stock Appreciation Rights, Limited Rights and Supplemental
Bonuses to Employees of First Seismic Corporation (the "Company"), and such
of its subsidiaries (as defined in Section 425(f) of the Internal Revenue
Code of 1986 (the "Code")) as the Board of Directors of the Company (the
"Board") shall from time to time designate ("Participating Subsidiaries"), in
order to advance the interests of the Company and its Participating
Subsidiaries through the motivation, attraction and retention of their
respective Employees.

II.      INCENTIVE STOCK OPTIONS AND NON-INCENTIVE STOCK OPTIONS

         The Stock Options granted under the Plan may be either;

         (a) Incentive Stock Options ("ISOs") which are intended to be
         "Incentive Stock Options" as that term is defined in Section 422A of
         the Code; or

         (b) Nonstatutory Stock Options ("NSOs") which are intended to be
         options that do not qualify as "Incentive Stock Options" under
         Section 422A of the Code.

All Stock Options shall be ISOs unless the Option Agreement clearly
designates the Stock Options granted thereunder, or a specified portion
thereof, as NSOs. Subject to the other provisions of the Plan, a Participant
may receive ISOs and NSOs at the same time, provided that the ISOs and NSOs
are clearly designated as such.

         Except as otherwise expressly provided herein, all of the provisions
and requirements of the Plan relating to Stock Options shall apply to ISOs
and NSOs.

III.     ADMINISTRATION

         3.1  COMMITTEE.  With respect to grants of Stock Options to
Employees other than directors of the Company and grants of Stock
Appreciation Rights, Limited Rights and Supplemental Bonuses to Employees
other than officers and directors of the Company, the Plan shall be
administered by a committee ("Committee") composed of at least three members
of the Board of Directors. With respect to grants of Stock Options to
directors and grants of Stock Appreciation Rights, Limited Rights and
Supplemental Bonuses to officers and directors, the Plan shall be
administered by the Board of Directors, a majority of whom are Disinterested
Persons and a majority of the Directors acting on Plan matters are
Disinterested Persons, or by a committee of three more

<PAGE>

persons, all of whom are Disinterested Persons. Such committee may be the
Committee if all of the members thereof are Disinterested Persons, or a
special committee appointed by the Board of Directors composed of at least
three Disinterested Persons. The Committee or the Board, as the case may be,
shall have full authority to administer the Plan, including authority to
interpret and construe any provision of the Plan and any Stock Option, Stock
Appreciation Right, Limited Right or Supplemental Bonus granted thereunder,
and to adopt such rules and regulations for administering the Plan as it may
deem necessary in order to comply with the requirements of the Code or in
order that Stock Options that are intended to be ISOs will be classified as
incentive stock options under the Code, or in order to conform to any
regulation or to any change in any law or regulation applicable thereto. The
Committee or the Board may delegate any of its responsibilities under the
Plan, other than its responsibility to grant Stock Options or Limited Rights,
to determine whether the Stock Appreciation Rights or Supplemental Bonuses,
if any, payable to a Participant shall be paid in cash, in shares of Common
Stock or a combination thereof, or to interpret and construe the Plan. The
Board of Directors may reserve to itself any of the authority granted to the
Committee as set forth herein, and it may perform and discharge all of the
functions and responsibilities of the Committee at any time that a duly
constituted Committee is not appointed and serving. All references in this
Plan to the "Committee" shall be deemed to refer to the Board of Directors
whenever the Board is discharging the powers and responsibilities of the
Committee, and to any special committee appointed by the Board to administer
particular aspects of the Plan.

         3.2  ACTIONS OF COMMITTEE.  All actions taken and all
interpretations and determinations made by the Committee in good faith
(including determinations of Fair Market Value) shall be final and binding
upon all Participants, the Company and all other interested persons. No
member of the Committee shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan,
and all members of the Committee shall, in addition to their rights as
directors, be fully protected by the Company with respect to any such action,
determination or interpretation.

IV.      DEFINITIONS

         4.1  "STOCK OPTION".  A Stock Option is the right granted under the

right to receive payment, in shares of Common Stock, cash or a combination of
shares of Common Stock and cash, of the Redemption Value of a specified
number of shares of Common Stock then purchasable under a Stock Option.

         4.3  "REDEMPTION VALUE".  The Redemption Value of shares of Common
Stock purchasable under a Stock Option shall be the amount, if any, by which

authorized but unissued or reacquired Common Stock (par value $.01 per share)
of the Company.

         4.5  "FAIR MARKET VALUE".  If the Common Stock is not traded
publicly, the Fair Market Value of a share of Common Stock on any date shall
be determined, in good faith, by the Board or the Committee after such
consultation with outside legal, accounting and other experts as the Board or

maintain a written record of its method of determining such value. If the
Common Stock is traded publicly, the Fair Market Value of a share of Common
Stock on any date shall be the average of the representative closing bid and
asked prices, as quoted by the National Association of Securities Dealers
through NASDAQ (its automated system for reporting quotes), for the date in
question or, if the Common Stock is listed on the NASDAQ National Market

Transaction, tender offer or exchange offer, or (y) the highest Fair Market
Value per share during the period commencing thirty days prior to a Change in
Control and ending immediately prior to the date the Limited Right is
exercised, over (b) the Option Price per share of a specified number of
shares of Common Stock then purchasable under a Stock Option to which such

fees) paid or to be paid for a share of Common Stock (whether by way of
exchange, conversion, distribution or upon liquidation or otherwise) in any
Transaction, tender offer or exchange offer occurring prior to the date on
which such Limited Right is exercised. If the consideration paid or to be
paid in any such Transaction, tender offer or exchange offer shall consist,
in whole or in part, of consideration other than cash, the Committee shall
take such action, as in its judgment it deems appropriate, to establish the
cash value of such consideration, but such valuation shall not be less than
the value, if any, attributed to such consideration by any party to such
Transaction, tender offer or exchange offer other than the Company.

         Securities Exchange Act of 1934, as amended), directly or
         indirectly, in one or more transactions, without the consent of the
         Company's Board of Directors, of thirty-five percent (35%) or more
         of the combined voting power of the outstanding shares of capital
         stock of the Company entitled to vote generally in the election of
         directors.

              (B)  Individuals who at the beginning of any period of three
         (3) consecutive years constitute the entire Board of Directors of

merger of the Company in which the Company is not the surviving corporation
other than a merger solely to effect a reincorporation or a merger of the
Company as to which stockholder approval is not required pursuant to Sections

lease, exchange or other transfer (in one transaction or a series of related
transactions) of 50% or more of the assets or earnings power of the Company,
or (C) the adoption of any plan or proposal for the liquidation or
dissolution of the Company.

V.       ELIGIBILITY AND PARTICIPATION

         5.1  ELIGIBLE EMPLOYEES.  Grants of Stock Options, Stock
Appreciation Rights, Limited Rights and Supplemental Bonuses may be made to
Employees of the Company or any Participating Subsidiary. Any director of the
Company or of a Participating Subsidiary who is also an Employee shall also
be eligible to receive Stock Options, Stock Appreciation Rights, Limited
Rights and Supplemental Bonuses, but directors who are not Employees shall
not be eligible to receive Stock Options, Stock Appreciation Rights, Limited
Rights or Supplemental Bonuses under the Plan. The Committee shall from time
to time determine the Employees to whom Stock Options shall be granted, the
number of shares of Common Stock subject to each Stock Option to be granted
to each such Employee, the Option Price of such Stock Options, all as
provided in this Plan.

         5.2  OPTION PRICE.  The Option Price of any ISO shall be not less
than the Fair Market Value of a share of Common Stock on the date on which
the Stock Option is granted, but the Option Price of an NSO may be less than
the Fair Market Value on the date the NSO is granted if the Committee so
determines. If an ISO is granted to an Employee who then owns stock
possessing more than 10% of the total combined voting power of all classes of
stock of the Company or any parent or subsidiary corporation of the Company,
the Option Price of such ISO shall be at least 110% of the Fair Market Value
of the Common Stock subject to the ISO at the time such ISO is granted, and
such ISO shall not be exercisable after five years after the date on which it
was granted.

         5.3  OPTION AGREEMENT.  Each Stock Option shall be evidenced by a
written agreement ("Option Agreement") containing such terms and provisions
as the Committee may determine, subject to the provisions of this Plan.

VI.      SHARES OF COMMON STOCK SUBJECT TO THE PLAN

         6.1  MAXIMUM NUMBER.  The maximum aggregate number of shares of
Common Stock that may be made subject to Stock Options shall be 500,000
authorized but unissued shares. The aggregate Fair Market Value (determined
as of the time the ISO is granted) of the stock as to all ISOs granted to an
individual may first become exercisable in a particular calendar year may not
exceed $100,000. If any shares of Common Stock subject to Stock Options are
not purchased or otherwise paid for before such Stock Options expire, such
shares may again be made subject to Stock Options.

         6.2  CAPITAL CHANGES.  In the event any changes are made to the
shares of Common Stock (whether by reason of merger, consolidation,
reorganization, recapitalization, stock dividend in excess of one percent
(1%) at any single time, stock split, combination of shares, exchange of
shares, change in corporate structure or otherwise), appropriate adjustments
shall be made in: (i) the number of shares of Common Stock theretofore made
subject to Stock Options, and in the purchase price of said shares; and (ii)
the aggregate number of shares which may be made subject to Stock Options. If
any of the foregoing adjustments shall result in a fractional share, the
fraction

                                      -5-
<PAGE>

shall be disregarded, and the Company shall have no obligation to make any
cash or other payment with respect to such a fractional share.

VII.     Exercise of Stock Options

         7.1  TIME OF EXERCISE.  Subject to the provisions of the Plan,
including without limitation Sections 7.3 and 7.8, the Committee, in its
discretion, shall determine the time when a Stock Option, or a portion of a
Stock Option, shall become exercisable, and the time when a Stock Option, or
a portion of a Stock Option, shall expire. Such time or times shall be set
forth in the Option Agreement evidencing such Stock Option. An ISO shall
expire, to the extent not exercised, no later than the tenth anniversary of
the date on which it was granted, and an NSO shall expire, to the extent not
exercised, no later than 10 years and one day after the date on which it was
granted. The Committee may accelerate the vesting of any Participant's Stock
Option by giving written notice to the Participant. Upon receipt of such
notice, the Participant and the Company shall amend the Option Agreement to
reflect the new vesting schedule. The acceleration of the exercise period of
a Stock Option shall not affect the expiration date of that Stock Option.

         7.2  EXCHANGE OF OUTSTANDING STOCK.  The Committee, in its sole
discretion, may permit a Participant to surrender to the Company shares of
the Common Stock previously acquired by the Participant as part of full
payment for the exercise of a Stock Option. Such surrendered shares shall be
valued at their Fair Market Value on the date of exercise. Unless otherwise
determined by the Committee, any such shares surrendered by the Participant
shall have been held by him for at least six months prior to surrender.

         7.3  USE OF PROMISSORY NOTE; EXERCISE LOANS.  The Committee may, in
its sole discretion, impose terms and conditions, including conditions
relating to the manner and timing of payments, on the exercise of Stock
Options. Such terms and conditions may include, but are not limited to,
permitting a Participant to deliver to the Company his promissory note as
full or partial payment for the exercise of a Stock Option; provided that,
with respect to any promissory note given as payment or partial payment for
the exercise of an ISO, all terms of such note shall be determined at the
time a Stock Option is granted and set forth in the Option Agreement. The
Committee, in its sole discretion, may authorize the Company to make a loan
to a Participant in connection with the exercise of Stock Options, or
authorize the Company to arrange or guaranty loans to a Participant by a
third party.

         7.4  STOCK RESTRICTION AGREEMENT.  The Committee may provide that
shares of Common Stock issuable upon the exercise of a Stock Option shall,
under certain conditions, be subject to restrictions whereby the Company has
a right of first refusal with respect to such shares or a right or obligation
to repurchase all or a portion of such shares, which restrictions may survive
a Participant's term of employment with the Company. The acceleration of time
or times at which the option becomes exercisable may be conditioned upon the
Participant's agreement to such restrictions.

                                      -6-
<PAGE>

         7.5  TERMINATION OF EMPLOYMENT BEFORE EXERCISE. (If a Participant's
employment with the Company or a Participating Subsidiary shall terminate for
any reason other than the Participant's disability, any Stock Option then
held by the Participant, to the extent then exercisable under the applicable
Option Agreement(s), shall remain exercisable after the termination of his
employment for a period of three months.) If the Participant's employment is
terminated because the Participant is disabled within the meaning of Section
22(e)(3) of the Code, any Stock Option then held by the Participant, to the
extent then exercisable under the applicable Option Agreement(s), shall
remain exercisable after the termination of his employment for a period of
twelve months (but in no event beyond ten years from the date of grant of the
Stock Option). If the Stock Option is not exercised during the applicable
period, it shall be deemed to have been forfeited and of no further force or
effect.

         7.6  DISPOSITION OF FORFEITED STOCK OPTIONS.  Any shares of Common
Stock subject to Stock Options forfeited by a Participant shall not
thereafter be eligible for purchase by the Participant but may be made
subject to Stock Options granted to other Participants.

         7.7  GRANT OF SUPPLEMENTAL BONUSES.  The Committee, either at the
time of grant or at any time prior to exercise of any Stock Option, Limited
Right or Stock Appreciation Right, may provide for a Supplemental Bonus from
the Company or Participating Subsidiary in connection with a specified number
of shares of Common Stock then purchasable, or which may become purchasable,
under a Stock Option, or a specified number of Stock Appreciation Rights or
Limited Rights which may be or become exercisable. The grant of a
Supplemental Bonus, sufficient to discharge the entire tax liability of the
recipient (as described below), shall be deemed to have been made in the case
of each Limited Right granted under Section 9.3 hereof, and no further
Committee action shall be necessary to authorize such a Supplemental Bonus
upon the authorization of a grant of any such Limited Right; PROVIDED,
HOWEVER, that the Committee may, in its discretion, determine to rescind any
or all such grants of Supplemental Bonuses at any time prior to the
occurrence of a Change in Control. A Supplemental Bonus shall be payable
upon the exercise of the NSO, Limited Right or Stock Appreciation Right with
regard to which such Supplemental Bonus was granted; provided, that if the
Participant is subject to Section 16(b) of the Securities Exchange Act of
1934, as amended, the Committee may provide that such Supplemental Bonus will
be calculated and paid six months after such exercise. A Supplemental Bonus
shall not exceed the amount necessary to reimburse the Participant for the
income tax liability incurred by him upon the exercise of the Stock Option or
upon the exercise of such Stock Appreciation Right or Limited Right,
calculated using the maximum combined federal and applicable state income tax
rates then in effect and taking into account the tax liability arising from
the Participant's receipt of the Supplemental Bonus. The Committee may, in
its discretion, elect to pay any part or all of the Supplemental Bonus in:
(i) cash; (ii) shares of Common Stock; or (iii) any combination of cash and
shares of Common Stock; provided that bonuses payable in respect of Limited
Rights shall be payable only in cash. The provisions of Section 8.3 shall
apply to the giving of notice, the determination of the number of shares to
be delivered, and the time for delivering shares. In applying Section 8.3,
the Supplemental Bonus shall be treated as if it were a Stock Appreciation
Right that the Participant exercised on the day the Supplemental Bonus

                                      -7-
<PAGE>

became payable. Shares of Common Stock issued pursuant to this Section 7.7
shall not be deemed to have been issued upon the exercise of a Stock Option
for purposes of the imitations imposed by Section 6.1 of the Plan.

         7.8  OPTION VESTING UPON CHANGE OF CONTROL OF THE COMPANY. In the
event of a Change of Control of the Company, as that term is defined in
Section 4.10 of this Plan, the vesting of Stock Options granted pursuant to
the Plan shall automatically be accelerated, so that all Stock Options
outstanding at the time of such Change of Control will be exercisable
immediately.

VIII.    STOCK APPRECIATION RIGHTS

         8.1  GRANT OF STOCK APPRECIATION RIGHTS.  The Committee may, from
time to time, grant Stock Appreciation Rights to a Participant with respect
to not more than the number of shares of Common Stock which are, or may
become, purchasable under any Stock Option held by the Participant. The
Committee may, in its sole discretion, specify the terms and conditions of
such rights, including without limitation the time period or time periods
during which such rights may be exercised and the date or dates upon which
such rights shall expire and become void and unexercisable; provided,
however, that in no event shall such rights expire and become void and
unexercisable later than the time when the related Stock Option is exercised,
expires or terminates. Each Participant to whom Stock Appreciation Rights are
granted shall be given written notice advising him of the grant of such
rights and specifying the terms and conditions of the rights, which shall be
subject to all the provisions of this Plan.

         8.2  EXERCISE OF STOCK APPRECIATION RIGHTS.  Subject to Section 8.3,
and in lieu of purchasing shares of Common Stock upon the exercise of a Stock
Option held by him, a Participant may elect to exercise the Stock
Appreciation Rights, if any, he has been granted and receive payment of the
Redemption Value of all, or any portion, of the number of shares of Common
Stock subject to such Stock Option with respect to which he has been granted
Stock Appreciation Rights; provided, however, that the Stock Appreciation
Rights may be exercised only when the Fair Market Value of the Common Stock
subject to such Stock Option exceeds the exercise price of the Stock Option.
A Participant shall exercise his Stock Appreciation Rights by delivering a
written notice to the Committee specifying the number of shares with respect
to which he exercises Stock Appreciation Rights and agreeing to surrender the
right to purchase an equivalent number of shares of Common Stock subject to
his Stock Option. If a Participant exercises Stock Appreciation Rights,
payment of his Stock Appreciation Rights shall be made in accordance with
Section 8.3 on or before the 90th day after the date of exercise of the Stock
Appreciation Rights.

         8.3  FORM OF PAYMENT.  If a Participant elects to exercise Stock
Appreciation Rights as provided in Section 8.2, the Committee may, in its
absolute discretion, elect to pay any part or all of the Redemption Value of
the shares with respect to which the Participant has exercised Stock
Appreciation Rights in: (i) cash; (ii) shares of Common Stock; or (iii) any
combination of cash and shares of Common Stock. The Committee's election
pursuant to this Section 8.3 shall be made by giving written notice to the
Participant within said 90-day period, which notice shall specify the

                                      -8-
<PAGE>

portion which the Committee elects to pay in cash, shares of Common Stock or
a combination thereof. In the event any portion is to be paid in shares of
Common Stock, the number of shares to be delivered shall be determined by
dividing the amount which the Committee elects to pay in shares of Common
Stock by the Fair Market Value of one share of Common Stock on the date of
exercise of the Stock Appreciation Rights. Any fractional share resulting
from any such calculation shall be disregarded. Said shares, together with
any cash payable to the Participant, shall be delivered within said 90-day
period.

IX.      LIMITED RIGHTS

         9.1  GRANT OF LIMITED RIGHTS.  The Committee shall grant Limited
Rights to a Participant concurrently with the grant of each Stock Option to
such Participant. Such Limited Rights shall be exercisable with respect to
the number of shares of Common Stock which are, or may become, purchasable
under any such Stock Option. The Committee may, in its sole discretion,
specify the terms and conditions of such rights, including without limitation
the date or dates upon which such rights shall expire and become void and
unexercisable. In any event, Limited Rights shall not be exercisable within
six (6) months from the date of grant of the Limited Right. Each Participant
to whom Limited Rights are granted shall be given written notice advising him
of the grant of such rights and specifying the terms and conditions of the
rights, which shall be subject to all the provisions of this Plan.

         9.2  EXERCISE OF LIMITED RIGHTS.  Except as provided in Section 9.3,
and subject to the limitations set forth in Section 9.1, a Limited Right
may be exercised only during the period beginning on the first day following
the occurrence of a Change in Control and ending on the thirtieth day
following such date; provided, however, that if the Change in Control occurs
prior to the expiration of six months from the date of grant of a Limited
Right, then such Limited Right shall be exercisable for a period of 30 days
following expiration of such six-month period. Upon the occurrence of a
tender offer or exchange constituting a Change in Control, a Limited Right
may be exercised in such manner regardless of whether the Board supports or
opposes such tender offer or exchange offer. A Limited Right may be exercised
regardless of whether the Stock Option to which such Limited Right relates is
then exercisable. A Participant shall exercise his Limited Rights by
delivering a written notice to the Committee specifying the number of shares
with respect to which he exercises Limited Rights and agreeing to surrender
the right to purchase an equivalent number of shares of Common Stock subject
to his Stock Option. If a Participant exercises Limited Rights, payment of
his Limited Rights shall be made in accordance with Section 9.4 on or before
the thirtieth day after the date of exercise of the Limited Rights. A Limited
Right shall remain exercisable during the exercise periods described above in
this Section 9.2 in the event of a termination of employment of the
Participant holding the Limited Right after a Change in Control.
Notwithstanding the above, upon a termination of the employment of the holder
of the Limited Right before the occurrence of any Change in Control, the
Limited Right shall expire immediately. Upon the death or disability of the
holder of the Limited Right, the Limited Right shall be exercisable only by
the Participant or by such Participant's estate, personal representative or
beneficiary who has acquired the Stock Option by will or the laws of descent
and distribution.

                                      -9-
<PAGE>

         9.3  LIMITED RIGHTS TRIGGERED BY A CHANGE IN CONTROL.  If a Change
in Control occurs, then Limited Rights shall be deemed to have been granted
immediately, covering all shares of Common Stock available for grant under
Section 6.1 (the "Available Shares") to all those Participants then holding
unexercised and unexpired Stock Options, such that each such Participant
shall receive Limited Rights with respect to a number of shares of Common
Stock equal to the product computed by multiplying (i) the number of
Available Shares by (ii) a fraction, the numerator of which is the number of
shares of Common Stock then subject to Stock Options held by such
Participant, and the denominator of which is the total number of shares of
Common Stock then subject to Stock Options held by all Participants. The
amount payable to each such Participant in respect of such Limited Right
shall equal the amount computed in accordance with Section 4.7; provided,
that the option price per share shall be deemed to be the weighted average of
the exercise prices of each of such Participant's then outstanding Stock
Options. No notice of exercise need be delivered by the Participant as to the
Limited Rights described in this Section 9.3, but rather such Limited Rights
shall be deemed to have been exercised on the date which is six months after
the occurrence of the Change in Control and payment therefor shall be made in
accordance with Section 9.4 on or before the thirtieth day after the date of
such exercise. Notwithstanding the foregoing, no Limited Rights shall be
deemed to be granted under this Section 9.3 if the Board approves the event
constituting a Change in Control prior to the occurrence of such event, but
only if a majority of the directors acting favorably on such matter are
Continuing Directors.

         9.4  FORM OF PAYMENT.  If a Participant elects to exercise Limited
Rights as provided in Section 9.2, or in the case of the deemed exercise of
Limited Rights pursuant to Section 9.3, the Company shall pay to the
Participant in cash the amount set forth in Section 4.7 hereof, calculated
with respect to the shares as to which the Participant has exercised Limited
Rights, within thirty days of the date of exercise of the Limited Rights. If
such amount is not paid in full within the prescribed period, the Company
shall be liable to such Participant for the costs of collection of such
amount, including attorney's fees.

         9.5  TERMINATION.  When a Limited Right is exercised, the Stock
Option to which it relates, if any, shall cease to be exercisable to the
extent of the number of shares of Common Stock with respect to which such
Limited Right was exercised. Upon the exercise or termination of a Stock
Option, Limited Rights granted with respect thereto shall terminate to the
extent of the number of shares as to which such Stock Option was exercised or
terminated.

X.       NO CONTRACT OF EMPLOYMENT

         Nothing in this Plan shall confer upon the Participant the right to
continue in the employ of the Company, or any Participating Subsidiary, nor
shall it interfere in any way with the right of the Company, or any such
Participating Subsidiary, to discharge the Participant at any time for any
reason whatsoever, with or without cause. Nothing in the Article X shall
affect any rights or obligations of the Company or any Participant under any
written contract of employment.

                                      -10-
<PAGE>

XI.      No Rights as a Stockholder

         A Participant shall have no rights as a stockholder with respect to
any shares of Common Stock subject to a Stock Option. Except as provided in
Section 6.2, no adjustment shall be made in the number of shares of Common
Stock issued to a Participant, or in any other rights of the Participant upon
exercise of a Stock Option by reason of any dividend, distribution or other
right granted to stockholders for which the record date is prior to the date
of exercise of the Participant's Stock Option.

XII.     Assignability

         No Stock Option, Stock Appreciation Right, Limited Right or
Supplemental Bonus right granted under this Plan, nor any other rights
acquired by a Participant under this Plan, shall be assignable or
transferable by a Participant, other than by will or the laws of descent and
distribution, and are exercisable, during his lifetime, only by him.
Notwithstanding the preceding sentence, the Committee may, in its sole
discretion, permit the assignment or transfer of an NSO and the exercise
thereof by a person other than a Participant, on such terms and conditions as
the Committee in its sole discretion may determine. Any such terms shall be
determined at the time the NSO is granted, and shall be set forth in the
Option Agreement. In the event of his death, the Stock Option or any Stock
Appreciation Right, Limited Right or Supplemental Bonus right may be
exercised by the Personal Representative of the Participant's estate or, if
no Personal Representative has been appointed, by the successor or successors
in interest determined under the Participant's will or under the applicable
laws of descent and distribution.

XIII.    Merger or Liquidation of the Company

         If the Company or its stockholders enter into an agreement to
dispose of all, or substantially all, of the assets or outstanding capital
stock of the Company by means of a sale or liquidation, or a merger or
reorganization in which the Company is not the surviving corporation, all
Stock Options outstanding under the Plan as of the day before the
consummation of such sale, liquidation, merger or reorganization, to the
extent not exercised, shall for all purposes under this Plan become
exercisable in full as of such date even though the dates of exercise
established pursuant to Section 7.1 have not yet occurred, unless the Board
shall have prescribed other terms and conditions to the exercise of the Stock
Options, or otherwise modified the Stock Options.

XIV.     Amendment

         The Board may from time to time alter, amend, suspend or discontinue
the Plan, including, where applicable, any modifications or amendments as it
shall deem advisable in order that ISOs will be classified as incentive stock
options under the Code, or in order to conform to any regulation or to any
change in any law or regulation applicable thereto; provided, however, that
no such action shall adversely affect the rights and obligations with respect
to Stock Options, Stock Appreciation Rights and Limited Rights at any time
outstanding under the Plan; and provided further that no such action shall,
without the approval of the stockholders of the Company, (i) increase the
maximum

                                      -11-
<PAGE>

number of shares of Common Stock that may be made subject to Stock Options
(unless necessary to effect the adjustments required by Section 6.2), (ii)
materially increase the benefits accruing to Participants under the Plan, or
(iii) materially modify the requirements [ILLEGIBLE] eligibility for
participation in the Plan.

XV.      Registration of Optioned Shares

         The Stock Options shall not be exercisable unless the purchase of
such optioned shares is pursuant to an applicable effective registration
statement under the Securities Act of 1933, as amended, or unless, in the
opinion of counsel to the Company, the proposed purchase of such optioned
shares would be exempt from the registration requirements of the Securities
Act of 1933, as amended, and from the registration or qualification
requirements of applicable state securities laws.

XVI.     Withholding Taxes

         The Company or Participating Subsidiary may take such steps as it
may deem necessary or appropriate for the withholding of any taxes which the
Company or the Participating Subsidiary is required by any law or regulation
or any governmental authority, whether federal, state or local, domestic or
foreign, to withhold in connection with any Stock Option, Stock Appreciation
Right, Limited Right or Supplemental Bonus, including, but not limited to,
the withholding of all or any portion of any payment or the withholding of
issuance of shares of Common Stock to be issued upon the exercise of any
Stock Option or Stock Appreciation Right or upon payment of any Limited Right
or Supplemental Bonus, until the Participant reimburses the Company or
Participating Subsidiary for the amount the Company or Participating
Subsidiary is required to withhold with respect to such taxes, or canceling
any portion of such payment or issuance in an amount sufficient to reimburse
itself for the amount it is required to so withhold.

XVII.    Brokerage Arrangements

         The Committee, in its discretion, may enter into arrangements with
one or more banks, brokers or other financial institutions to facilitate the
disposition of shares acquired upon exercise of Stock Options, Stock
Appreciation Rights or Supplemental Bonuses, including, without limitation,
arrangements for the simultaneous exercise of Stock Options, Stock
Appreciation Rights or Supplemental Bonuses, and sale of the shares acquired
upon such exercise.

XVIII.   Nonexclusivity of the Plan

         Neither the adoption of the Plan by the Board nor the submission of
the Plan to stockholders of the Company for approval shall be construed as
creating any limitations on the power or authority of the Board to adopt such
other or additional incentive or other compensation arrangements of whatever
nature as the Board may deem necessary or desirable or preclude or limit the
continuation of any other plan, practice or arrangement for the payment of
compensation or fringe benefits to employees generally, or to any class or
group of employees, which the Company or any Subsidiary now has [ILLEGIBLE] put
into effect, including, without limitation, any retirement, pension, savings
and

                                      -12-
<PAGE>

stock purchase plan, insurance, death and disability benefits and executive
short-term incentive plans.

XIX.     Effective Date

         This Plan was adopted by the Board of Directors and became effective
on July 16, 1990 and was approved by the Company's stockholders on June __,
1990. No Stock Options or Limited Rights shall be granted subsequent to ten
years after the effective date of the Plan. Stock Options or Limited Rights
outstanding subsequent to ten years after the effective date of the Plan
shall continue to be governed by the provisions of the Plan.

the registration requirements of the Securities Act;

         WHEREAS, the First Seismic wishes to establish certain other
restrictions on the sale of Common Stock owned by Benton, and the First
Seismic and Benton desire to set forth certain registration rights as to such
shares;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereby

sell any of all of its Registrable Shares into a successful First Seismic
secondary public offering and receive the net market proceeds per share
received by First Seismic from such an offering in accordance with the terms
of this Section 2.

         (b) If, at any time, First Seismic proposes to file a registration
statement in connection with the public offering of shares of Common Stock to
be sold by First Seismic for its own account under the Securities Act (other
than a registration on Forms S-4, S-8 or any successor forms), prior to such
filing, First Seismic shall give each Holder a Registration Notice. Within
five days after receipt by any Holder of a Registration Notice, such Holder
shall deliver to First Seismic a Participation Notice of such Holder's desire
to sell Registrable Shares under such registration. The Participation Notice
shall state the number of Registrable Shares to be disposed in such
registration; provided, however, such holder's right to registration of such
Registrable Shares shall be subject to any limitations in the number thereof
required by the underwriters pursuant to Section 5. Notwithstanding, a Holder
may exercise its rights under this section 2(b) no more than two times.

         (c) Upon receiving a Participation Notice in accordance with Section
2(b), First Seismic shall use reasonable efforts to promptly cause all such
Registrable Shares to be registered along with the other shares of Common
Stock to be registered.

         (d) The Registrable Shares proposed to be registered under any
registration statement under Section 2(b) hereof will be offered for sale at
the same public offering price as the shares of Common Stock offered for sale
by First Seismic.

                               FIRST SEISMIC CORPORATION
                             REGISTRATION RIGHTS AGREEMENT

each Holder so delivering a Participation Notice will execute and deliver a
custody agreement and power of attorney satisfactory to the First Seismic
with respect to the Registrable Shares to be registered (a "Custody
Agreement" and "Power of Attorney," respectively). The Custody Agreement and
Power of Attorney will provide, among other things, that such Holder will
deliver to and deposit in custody with the custodian named therein a
certificate or certificates representing such Registrable Shares (duly
endorsed in blank by the registered owner or owners thereof or accompanied by
duly executed stock powers in blank) and irrevocably appoint said custodian
and attorney-in-fact with full power and authority to act under the Custody
Agreement and Power of Attorney, respectively, on the Holder's behalf with
respect to matters specified therein, including the execution and delivery of
an underwriting agreement.

SECTION 3. OBLIGATIONS OF FIRST SEISMIC.

effect the registration of any Registrable Shares, First Seismic shall, as
expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
         with respect to such Registrable Shares and use reasonable efforts to
         cause such registration statement to become and remain effective;
         provided, however, that the First Seismic shall have no obligation to
         maintain the effectiveness of any registration statement filed
         hereunder or to cause the information therein to remain current for
         more than 90 days following such registration statement's effective
         date in the case of an underwritten public offering or for longer than
         such period as is customary and is required by the underwriter in the
         case of a firmly underwritten public offering.

                  (b) Prepare and file with the SEC such amendments and
         supplements to such registration statement and the prospectus used in
         connection with such registration statement as may be necessary to keep
         such registration statement effective in order to dispose of the shares
         registered thereunder in the manner described in the underwriting
         agreement executed in connection therewith and to comply with the
         provisions of the Securities Act with respect to the disposition of all
         securities covered by such registration statement; provided, however,
         that First Seismic shall have no obligation to maintain the
         effectiveness of any registration statement filed hereunder or to cause
         the information therein to remain current for more than 90 days
         following such registration statement's effective date in the case of
         an underwritten public offering or for longer than such period as is
         customary and is required by the underwriter in the case of a firmly
         underwritten public offering.

                  (c) Furnish to the Holders registering securities in such
         registration such numbers of copies of a prospectus, including a
         preliminary prospectus, in conformity with the requirements of the
         Securities Act, and such other documents as they may reasonably request
         in order to facilitate the disposition of Registrable Shares owned by
         the Holders.

                  (d) Use reasonable efforts to register and qualify the
         securities covered by such registration statement under such other
         securities or "Blue Sky" laws of such jurisdictions as

                               FIRST SEISMIC CORPORATION
                             REGISTRATION RIGHTS AGREEMENT
                                        -3-

<PAGE>

         shall be reasonably appropriate for the distribution of the securities
         covered by the registration statement; provided that First Seismic
         shall not be required in connection therewith or as a condition thereto
         to qualify to do business or to file a general consent to service of
         process in any such jurisdictions.

                  (e) With respect to any registration initiated by First
         Seismic pursuant to Section 2(b) hereof, First Seismic shall have the
         right to withdraw such registration at any time at its sole discretion
         without the consent or approval of any Holder including Registrable
         Shares in such registration.

SECTION 4. EXPENSES OF REGISTRATION.

         All expenses incurred in connection with a registration pursuant to
Section 2 or otherwise in which First Seismic permits a Holder to participate
(excluding underwriters' discounts and commissions applicable to Registrable
Shares), including all registration and qualification fees, printing and
accounting fees, and fees and disbursements of counsel for First Seismic and
the Holder, shall be borne by First Seismic.

         Each Holder of Registrable Shares shall pay the underwriters'
discounts and commissions applicable to the securities sold by such Holder.
In addition, each selling Holder shall pay its own costs for experts or
professionals (other than counsel) employed by it or on its behalf in
connection with the registration of Registrable Shares. No Holder shall have
the right to cause First Seismic to employ any expert or professional to act
on behalf of First Seismic.

SECTION 5. UNDERWRITING REQUIREMENTS.

         In connection with any offering involving an underwriting of shares
being issued by First Seismic, First Seismic shall not be required to include
any of the Holders' Registrable Shares in such underwriting unless the
Holders accept the terms of the underwriting as agreed upon between First
Seismic and the underwriters.

         Additionally, First Seismic shall be required to include in such
piggy-back registration under Section 2(b) only such quantity of the
Registrable Shares as will not, in the judgement of the underwriters,
jeopardize the success of the offering by First Seismic. If, however, the
underwriters have consented to inclusion in any such offering of securities
of any person other than First Seismic, then the Holders shall be entitled to
include such number of their Registrable Shares in such underwriting pro rata
to the total number of shares of Common Stock owned by all of such persons
who are entitled to sell securities in such offering (such apportionment
shall not include securities offered by First Seismic for its own account).
Subject to the above, in all cases the Holders collectively shall have the
right to include Registrable Shares in any registration under Section 2(b)
in an aggregate amount equal to at least fifty percent (50%) of the shares of
Common Stock being sold by all selling stockholders in such public offering.

SECTION 6. INDEMNIFICATION.

         (a) In the event of registration of any of the Registrable Shares
under the Securities Act, First Seismic will indemnify and hold harmless the
seller of such Registrable Shares, each underwriter of such

                               FIRST SEISMIC CORPORATION
                             REGISTRATION RIGHTS AGREEMENT
                                        -4-

<PAGE>

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

         (b) In the event of any registration of any of the Registrable
Shares under the Securities Act, each seller of the Registrable Shares,
severally and not jointly, will indemnify and hold harmless First Seismic,
each of its directors and officers and each underwriter (if any) and each
person, if any, who controls First Seismic or any such underwriter within the
meaning of the Securities Act or the Exchange Act, against losses, claims,
damages or liabilities, joint or several, to which First Seismic, such
directors and officers, underwriter or controlling person may become subject
under the Securities Act, Exchange Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon any untrue statement of a material fact contained in any
registration statement under which such Registrable Shares were registered
under the Securities Act, any preliminary prospectus or final prospectus
contained in the registration statement, or any amendment or supplement to
the registration statement, or arise out of or are based upon any omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, if the statement or omission was made in
reliance upon and in conformity with information furnished in writing to
First Seismic by or on behalf of such seller, specifically for use in
connection with the preparation of such registration statement, prospectus,
amendment or supplement.

         (c) Each party entitled to indemnification under this Section 6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought,
and shall permit the Indemnifying Party to assume the defense of any such
claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall
not unreasonably be withheld), and the Indemnified Party may participate in
such defense at such party's expense, and provided further that the failure
of any Indemnified Party to give notice as provided herein shall not relieve
the Indemnifying Party of its obligations under this Section 6. After notice
from the Indemnifying Party to the Indemnified Party of its election to
assume the defense of such claim or litigation, the Indemnifying Party will
not be liable to such Indemnified Party for any legal or other

                               FIRST SEISMIC CORPORATION
                             REGISTRATION RIGHTS AGREEMENT
                                        -5-

<PAGE>

expenses subsequently incurred by such Indemnified Party in connection with
the defense thereof other than reasonable costs of investigation, unless the
Indemnifying Party abandons the defense of such claim or litigation. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional, term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

SECTION 7. LOCKUP AGREEMENT.

         In connection with any such registration, upon the request of the

         1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT
         BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, UNLESS AND UNTIL SUCH SHARES
         ARE REGISTERED UNDER SUCH ACT, OR SUCH STATE LAWS, OR AN OPINION OF

RIGHTS.

From and after the date of this Agreement, First Seismic shall not enter into
any agreement with any holder or prospective holder of any securities of
First Seismic which provides for the granting to such holder of registration

rights of Holders hereunder or unless First Seismic first obtains the
Holders' of a majority of the Registrable Shares consent to the terms thereof.

First Seismic is given written notice by the Holder at the time of such
transfer stating the name and address of the transferee and identifying the
Registrable Shares with respect to which the rights under this Agreement are
being assigned. This Agreement shall also be binding upon and enforceable by
the heirs, executors, or other personal representatives of the Holders and
the successors and assigns of First Seismic.
