ITEM 1. BUSINESS
--------

General

Seitel, Inc. (the "Company") is a leading provider of seismic data and
related geophysical services and expertise to the petroleum industry. The
Company licenses its proprietary seismic data to oil and gas companies and
participates in petroleum exploration and development projects. See Note P to
the Company's Consolidated Financial Statements for financial information
relating to industry segments.

Seismic Operations

Since its inception in 1982, the Company has developed a proprietary
library of seismic data by contracting with crew companies to acquire data and
by buying existing data libraries from other companies. The Company's seismic
data library is primarily owned and marketed by Seitel Data, Ltd., a partnership
wholly-owned by the Company through subsidiaries, and Olympic Seismic, Ltd., a
wholly-owned Canadian subsidiary. The data library, which consists of both
two-dimensional ("2D") and three-dimensional ("3D") data, is marketed to major
and independent oil and gas companies under license agreements. Seismic surveys
and the analysis of seismic data for the identification and definition of
underground geological structures are principal techniques used in oil and gas
exploration and development to determine the existence and location of
subsurface hydrocarbons.

At December 31, 1999, the Company owned approximately 1,150,000 linear
miles of 2D and approximately 16,300 square miles of 3D seismic data which it
maintained in its library and the Company marketed an additional 270,000 linear
miles of 2D data owned by others. The Company's seismic data library constitutes
the largest seismic database marketed publicly in North America based solely on
management's knowledge and beliefs regarding the industry. The Company's U.S.
seismic surveys extend to virtually every major domestic exploration and
development region, with the majority of the seismic surveys covering onshore
and offshore the U.S. Gulf Coast. In addition, the Company's international
seismic surveys are concentrated in Western Canada and the Continental Shelf
offshore the United Kingdom and Ireland.

The Company's marketing team of 20 seismic sales specialists markets data
from its library and from newly initiated seismic surveys. The Company's
marketing philosophy is that seismic data, like most other products, must be
sold aggressively as opposed to waiting passively for customer purchases. The
marketing team monitors energy industry exploration and development activities
through close interaction with oil and gas companies on a daily basis to
maximize seismic sales opportunities.

The Company has a 14 member staff of geoscientists dedicated to its seismic
operations, who have in excess of 270 years of collective geophysical
experience. Together, the marketing team and geoscientists help clients evaluate
their respective seismic requirements, design seismic data programs to meet
market demand, and supervise the reprocessing of data in the Company's library
to enhance future resales.

Three-dimensional seismic data provides a graphic geophysical depiction of
the earth's subsurface from two horizontal dimensions and one vertical
dimension, rendering a more detailed picture than 2D data, which presents a
cross-sectional view from one vertical and one horizontal dimension. The more
comprehensive geophysical information provided by 3D surveys significantly
enhances an interpreter's ability to evaluate the probability of the existence
and location of oil and gas deposits. The proper use of 3D surveys can
significantly increase drilling success rates and, correspondingly,
significantly lower exploration and development finding costs. However, the cost
to create 3D seismic data is significantly more than the cost to create 2D
seismic data, particularly for onshore data. As a result, 2D data remains
economically more efficient for preliminary, broad-scale exploration evaluation
and to determine the location for 3D surveys. Also, the best way to design a 3D
survey is from 2D data grids of the respective area. The 3D surveys can then be
used for more site-specific analysis to maximize actual drilling potential.

The Company creates new seismic data for its library through multi-client
surveys. Prior to undertaking a seismic survey, the Company pre-licenses the
data to several oil and gas companies. The license fee commitments from these
customers cover the majority of the costs of the survey. The Company's
investment in the survey is limited to the excess of the cost of the survey over
the customer license fee commitments. The customers share in the expense of a
survey, which reduces their cost of the survey while the Company reduces its
initial capital investment in the survey. In a multi-client survey, the Company
retains ownership of the newly created data, which is added to its data library.
The Company then markets licenses to use the data to other customers. Seismic




data cannot be transferred by a licensee to another party; each individual user
must purchase a license. The Company contracts with seismic acquisition crew
companies to conduct both onshore and offshore seismic surveys.

The Company has developed fully-integrated 3D technology and operations,
which extend from its expansive 2D seismic library from which to best design the
parameters for 3D surveys, its large and growing 3D data library, a processing
center and proprietary computer technology coupled with extensive geophysical
application expertise to effectively interpret 3D data.

Oil and Gas Exploration and Production Operations

In addition to licensing its seismic data to customers, the Company also
utilizes its seismic expertise to participate directly in oil and gas projects.
The Company participates in these projects as a working interest owner, sharing
costs and revenues of oil and gas exploration and production projects with other
oil and gas companies. The Company's strategy is to combine its 3D and 2D
seismic expertise and related geophysical expertise with the geological,
engineering and drilling expertise and land positions of oil and gas companies
in exploration and development programs. The Company believes that this
combination will result in higher drilling success rates, thereby allowing the
Company to participate in oil and gas exploration and development on a
relatively low cost and low risk basis, and to build an asset base of oil and
gas reserves which complement its seismic data library.

Since its formation in 1993, the Company's wholly-owned exploration and
production subsidiary, DDD Energy, Inc. ("DDD Energy"), has entered into and
maintained cost and revenue-sharing relationships with more than 100 oil and gas
companies and, in doing so, has received the benefit of these oil and gas
companies' land, geological, engineering and drilling staffs. DDD Energy has
conducted over 2,000 square miles of advanced 3D surveys, located primarily in
the Gulf Coast areas of onshore Texas, Louisiana, Alabama and Mississippi, as
well as California and Arkansas. DDD Energy's working interest in these projects
ranges from approximately 10% to 90%, with an average working interest of
approximately 31%. More than 160 square miles of 3D surveys are scheduled to be
conducted in 2000 by DDD Energy and its partners. The majority of the well
locations pinpointed by the surveys that have already been completed and
interpreted should be drilled during the next three years. DDD Energy
exclusively utilizes the Company's processing and interpretation technology and
operations to provide optimum quality control and confidentiality for the
exploration and production programs in which DDD Energy participates.

From March 1993 through December 31, 1999, DDD Energy has participated in
the drilling of 300 wells, 205 of which were commercially productive for a 68%
success rate.

In November 1999, the Company's 19% owned subsidiary, Vision Energy, Inc.
("Vision Energy"), filed a registration statement with the Securities and
Exchange Commission ("SEC") to accomplish the spin-off of DDD Energy through an
initial public offering. In the proposed offering, Vision Energy would acquire
all of the stock of DDD Energy from the Company in exchange for the issuance of
shares of Vision Energy stock to the Company, and the Company would sell most of
these Vision Energy shares in the public offering for cash. Completion of the
offering is expected to occur during the second or third quarter of 2000;
however, its completion is dependent upon market conditions and other factors.
The Company continues to explore opportunities to maximize the value of DDD
Energy.

Customers

The Company markets its seismic data to major and independent oil and gas
companies. The Company generally sells its oil and gas to numerous customers
through the operators of its oil and gas properties. No one customer accounted
for as much as 10% of the Company's revenues during the years 1999, 1998 or
1997. As a result, the Company does not believe that the loss of any customer
would have a material adverse impact on its seismic or oil and gas business.

Competition

The creation and resale of seismic data are highly competitive in North
America. There are a number of independent oil-service companies that create and
market data, and numerous oil and gas companies create seismic data and maintain
their own seismic data banks. However, as a result of the energy industry's
collapse in 1985 and major industry consolidation in the 1990's, significant
seismic competitors to the Company have been reduced from approximately 15
companies in 1985 to less than 10 today. The Company's largest competitors, most
of whom are engaged in acquiring seismic data as well as a data library, are



Baker Hughes, Petroleum Geo-Services, Schlumberger, TGS Nopec, Veritas DGC and
Compagnie Generale de Geophysique. In addition, the Company has positioned
itself to take advantage of the increased outsourcing trend by exploration and
production companies for their seismic data services. The Company believes it
can compete favorably because of the expansiveness of its data library base, the
expertise of its marketing staff and the technical proficiency and exploration
experience of its geoscientists. These resources enable the Company to provide
high-quality service and to create and market high-grade data.

In the oil and gas exploration and production business, there are numerous
oil and gas companies competing for the acquisition of mineral properties. The
Company believes it can participate effectively in the exploration for and
development of natural gas and crude oil reserves because of its
fully-integrated seismic resources and geophysical expertise combined with the
geological and engineering experience and land positions of the Company's oil
and gas company partners.

Seasonality and Timing Factors

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

With respect to the Company's seismic licensing revenue, the Company's
results are influenced by oil and gas industry capital expenditure budgets and
spending patterns. These budgets are not necessarily spent in either equal or
progressive increments during the year, with spending patterns affected by
individual oil and gas company requirements as well as industry-wide conditions.
As a result, the Company's seismic data revenue does not necessarily flow evenly
or progressively on a sequential quarterly basis during the year. In addition,
certain weather-related events may delay the creation of seismic data for the
Company's library during any given quarter. Although the majority of the
Company's seismic resales are under $500,000 per sale, occasionally a single
data resale from the Company's library can be as large as $5 million or more.
Such large resales can materially impact the Company's results during the
quarter in which they occur, creating an impression of a trend of increasing
revenue that may not be achieved in subsequent periods.

With respect to revenue from the Company's oil and gas operations, bringing
a small number of high-production wells on line in a given quarter can
materially impact the results of that quarter since many of the wells in which
the Company participates experience high initial flow rates for the first 60 to
90 days of production and then taper off to a lower, steady rate for the
remainder of their lives. If several of these wells are brought on line in a
quarter, the results for that quarter will appear unusually strong, and then
later, when production decreases to its long-term, steady rate, the Company's
results may not be able to sustain the trend of increased performance indicated
by the strong results of the previous quarter. The Company's oil and gas
exploration and production operations also can 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
high percentage of gas reserves in the Company's portfolio and the seasonal
variations in gas prices, the Company's results from its oil and gas operations
also are subject to significant fluctuations due to variations in commodity
prices. In addition, some producing wells may be required to go off line
periodically for pipeline and other maintenance. The Company does not believe
that these fluctuations in quarterly results are indicative of the Company's
long-term prospects and financial performance.

See Note Q to the Company's Consolidated Financial Statements and
Management's Discussion and Analysis of Financial Condition and Results of
Operations.

Employees

As of December 31, 1999, the Company and its subsidiaries had 120 full-time
employees and two employees who devote part of their time to the Company who are
also officers of other corporations. None of the Company's employees are covered
by collective bargaining agreements. Of these employees, 82 are related to the
seismic operations and 20 are related to the oil and gas operations. The balance
provides accounting and administrative support for all operations. The Company
has employment contracts with five of its senior corporate executives.

Risk Factors

Any investment in our securities involves risk. Investors should carefully
consider, in addition to the other information contained in this report, the
risks described below before making any investment decision.



OUR BUSINESS COULD BE ADVERSELY AFFECTED BY LOW EXPLORATION, DEVELOPMENT
AND PRODUCTION SPENDING BY OIL AND GAS COMPANIES AND BY LOW OIL AND GAS PRICES.

Our seismic business depends upon exploration, development and production
spending by oil and gas companies. Although overall conditions in the oil and
gas industry have improved recently as a result of strong oil prices, the level
of capital expenditures by oil and gas companies has not been as quick to
recover. This could affect our seismic data operations. Any decreases in oil and
gas prices could result in decreased exploration, development and production
spending by oil and gas companies, which could affect our seismic data business.
Although oil and gas prices have increased recently, any future decline could
result in decreased revenues from our oil and gas exploration and production
business.

WE INVEST SIGNIFICANT AMOUNTS OF MONEY IN ACQUIRING AND PROCESSING SEISMIC
DATA FOR OUR DATA LIBRARY WITH ONLY PARTIAL UNDERWRITING OF THE COSTS BY
CUSTOMERS.

We invest significant amounts of money in acquiring and processing new
seismic data to add to our data library. Although we generally obtain customer
commitments covering in excess of 60% of the costs of acquiring and processing
this data, we assume the risk that we will not be able to fully recover our
portion of the costs through future licensing of the data. The amounts of these
future data licensing fees are uncertain and depend on a variety of factors,
including the market prices of oil and gas, customer demand for seismic data in
our library, availability of similar data from competitors and governmental
regulations affecting oil and gas exploration. Many of these factors are beyond
our control. In addition, the timing of these sales can vary greatly from period
to period. Technological or regulatory changes or other developments could
adversely affect the value of the data.

BECAUSE OUR BUSINESS IS CONCENTRATED IN THE U.S. GULF COAST AND CANADA, IT
COULD BE ADVERSELY AFFECTED BY DEVELOPMENTS IN THE OIL AND GAS BUSINESS THAT
AFFECT THESE AREAS.

Most of the seismic data in our seismic data library covers areas along the
U.S. Gulf Coast, offshore in the U.S. Gulf of Mexico or in Canada. Also, most of
our existing interests in oil and gas properties are located along the coast of
the U.S. Gulf of Mexico. Because of this geographic concentration, our results
of operations could be adversely affected by events relating primarily to one
these regions even if conditions in the oil and gas industry worldwide were
favorable. Some examples of possible events that would adversely affect the U.S.
Gulf Coast region would be changes in governmental regulations adversely
affecting offshore drilling in the U.S. Gulf of Mexico, shortages of drilling or
other necessary equipment in this region, or increases in gas transportation
costs from this region to the Northeastern U.S., where much of the gas produced
in this region is consumed.

THE AMOUNTS WE AMORTIZE FROM OUR DATA LIBRARY EACH PERIOD MAY FLUCTUATE,
AND THESE FLUCTUATIONS CAN AFFECT OUR REPORTED RESULTS OF OPERATIONS.

We amortize the cost of our multi-client data library based in part on our
estimates of future sales of data. These estimates are imprecise and may vary
from period to period depending upon market developments and our expectations.
Substantial changes in amortization rates can have a significant effect on our
reported results of operations.

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

We may not discover commercial quantities of oil and gas when we
participate in drilling wells. Our oil and gas operations could be adversely
affected by the occurrence of drilling hazards. These include:

o cratering;
o explosions;
o uncontrollable flows of oil, gas or well fluids;
o fires;
o pollution; and
o other environmental risks.

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. We do not act as operator in our oil and gas drilling
business and depend on our partners to minimize these operating risks.


WE HAVE RECORDED WRITE-DOWNS BECAUSE OF LOW OIL AND GAS PRICES AND MAY BE
REQUIRED TO DO SO AGAIN IN THE FUTURE. FUTURE WRITE-DOWNS WOULD RESULT IN A
CHARGE TO OUR EARNINGS AND POSSIBLE LOSSES.

Under SEC oil and gas accounting rules, we may have to write-down our
assets if oil and gas prices decline significantly or if we have significant
downward adjustments to our oil and gas reserves. We recorded a $9.6 million
pre-tax, $6.2 million after tax, non-cash write-down of the carrying value of
our proved oil and gas properties as of December 31, 1997 due to low oil and gas
prices. If oil and gas prices fall significantly, or if we have significant
downward reserve adjustments in the future, it is possible that additional
write-downs will occur again. These write-downs would result in a charge to our
earnings and possible losses, but would not impact cash flows from operating
activities.

OUR DEBT AGREEMENTS MAY LIMIT OUR FLEXIBILITY IN RESPONDING TO CHANGING
MARKET CONDITIONS OR IN PURSUING BUSINESS OPPORTUNITIES.

Our debt agreements contain restrictions and requirements relating to,
among other things:

o additional borrowing;
o maintaining financial ratios;
o granting liens on our assets;
o selling assets;
o paying dividends; and
o merging.

These restrictions and requirements may limit our flexibility in responding
to market conditions or in pursuing business opportunities that we believe would
have a positive effect on our business.

EXTENSIVE GOVERNMENTAL REGULATION OF OUR BUSINESS AFFECTS OUR DAILY
OPERATIONS.

Our seismic data customers are subject to extensive governmental
regulation. In addition, our oil and gas exploration and production operations
are subject to regulations. These regulations, among other things:

o govern environmental quality and pollution control; and
o limit rates of production.

New laws or regulations or changes to existing laws or regulations
affecting the oil and gas industry could reduce customer demand for our seismic
data or increase the operating costs of our oil and gas business.

LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS.

We depend on 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 business.

ITEM 2. PROPERTIES
----------

The Company, through its wholly-owned subsidiary DDD Energy, participates
in oil and gas exploration and development efforts. For estimates of the
Company's net proved and proved developed oil and gas reserves as of December
31, 1999, see Note S to the Company's Consolidated Financial Statements. There
are numerous uncertainties inherent in estimating quantities of proved reserves
and in projecting future rates of production and timing of development
expenditures, including many factors beyond the control of the producer. The
reserve data set forth in Note S to the Company's Consolidated Financial
statements represents only estimates. Reserve engineering is a subjective
process of estimating underground accumulations of natural gas and liquids,
including crude oil, condensate and natural gas liquids, that cannot be measured
in an exact manner. The accuracy of any reserve estimate is a function of the
amount and quality of available data and of engineering and geological
interpretation and judgment. As a result, estimates of different engineers
normally vary. In addition, results of drilling, testing and production
subsequent to the date of an estimate may justify revision of such estimate.
Accordingly, reserve estimates are often different from the quantities
ultimately recovered. The meaningfulness of such estimates is highly dependent
upon the accuracy of the assumptions upon which they were based.

In general, the volume of production from oil and gas properties owned by
the Company declines as reserves are depleted. Except to the extent that the
Company acquires additional properties containing proved reserves or conducts
successful exploration and development activities, or both, the proved reserves
of the Company will decline as reserves are produced. Volumes generated from
future activities of the Company are therefore highly dependent upon the level
of success in finding or acquiring additional reserves and the costs incurred in
so doing.

The following table sets forth the number of productive oil and gas wells
(including producing wells and wells capable of production) in which the Company
owned an interest as of December 31, 1999. Gross oil and gas wells include 10
with multiple completions. All of the wells are operated by the Company's oil
and gas company partners. A "gross" well is a well in which the Company owns a
working interest. "Net" wells refer to the sum of the fractional working
interests owned by the Company in gross wells.

ITEM 3. LEGAL PROCEEDINGS

The Company is involved from time to time in ordinary, routine claims and
lawsuits incidental to its business. In the opinion of management, uninsured
losses, if any, resulting from the ultimate resolution of these matters should
not be material to the Company's financial position or results of operations.

Dividend Policy

The Company did not pay cash dividends during 1998 or 1999, and it intends
to retain future earnings in order to provide funds for use in the operation and
expansion of its business. Because the payment of dividends is dependent upon
earnings, capital requirements, financial conditions, any required consents of
lenders and other factors, there is no assurance that dividends, whether in the
form of stock or cash, will be paid in the future.

of the Company's volumetric production payment.



Results of Operations

Seismic

Most oil and gas companies consider seismic data an essential tool to
generate and delineate drilling prospects for the oil and gas industry. Oil and
gas companies are increasingly using seismic data in oil and gas exploration and
development efforts to increase the probability of drilling success. By properly
utilizing seismic data, oil and gas companies can significantly increase
drilling success rates and reduce the occurrence of dry holes. By participating
in multi-client surveys, oil and gas companies can share the cost of expensive
surveys that they could not otherwise afford. Further, seismic can increase
recoveries of reserves from existing, mature oil fields by optimizing the
drilling location of development wells and by revealing additional, or
"step-out," locations that would not otherwise be apparent.


The Company generates seismic revenue by licensing data from our existing
data library and creating new data for customers. Revenue from the marketing of
seismic data was $109,671,000, $125,863,000 and $85,560,000 during 1999, 1998
and 1997, respectively. In May 1999, the Company made a management decision to
focus its marketing team on licensing of existing data ("library sales") that
would generate cash flow. Library sales in 1999 increased to the record level of
$63,058,000, an increase of 36% over the previous record year of $46,359,000 in
1998. The Company's decision to reduce data creation in 1999 caused total
seismic revenue to be lower than 1998 levels, but also reduced capital
expenditures, producing solid financial results under difficult industry
conditions. In 1998, the increase in seismic revenue from 1997 levels was
primarily attributable to increased efforts and investment in the creation of
new seismic data. In February 1999, the Company acquired substantially all of
the seismic assets of Amoco Canada, making Seitel, Inc. the largest seismic data
library company in North America.

As witnessed by the strength of the Company's library sales in 1999, demand
for its seismic data continues to be strong despite the uncertainty surrounding
oil and gas prices. Furthermore, demand for its 2D data continues to be strong,
with 1999 sales levels increasing over 1998 levels. The first three months of
2000 have produced higher than expected commodity prices which is expected to
generate strong cash flow for the oil and gas industry and lead to rising levels
of capital expenditures. This scenario should lead to improving demand for
Seitel, Inc. products and services, including our library data and new data
creation.

Data bank amortization amounted to $49,375,000, $57,117,000 and $35,163,000
for the years ended December 31, 1999, 1998 and 1997, respectively. The amount
of seismic data amortization fluctuates based on the level of seismic marketing
revenue. As a percentage of revenue from licensing seismic data, data bank
amortization was 46%, 46% and 42% for 1999, 1998 and 1997, respectively. These
changes between years are primarily due to the mix of sales of 2D and 3D data
amortized at varying percentages based on each data program's current and
expected future revenue. For a discussion of the Company's accounting policy
related to seismic data amortization refer to Note A of the Company's
Consolidated Financial Statements.

The Company's (and its industry's) seismic revenue trends are evaluated and
results are used in estimating future revenue expected to be received on its
seismic data. When economic conditions indicate, the Company may reduce its
estimates of future revenue, causing the amortization rate to rise and liquidity
and operating results to decline. If the Company perceives an impairment in
value due to reduced, or a lack of, estimated future revenue, a write-down of
the asset is recognized. In periods of upturn, the opposite may occur, except,
however, the prior write-downs are not reversed. Management believes that the
economic outlook for the Company's seismic business is stable and the
possibility for significant improvement exists.

Oil and Gas

Net volume and price information for the Company's oil and gas production
for the years ended December 31, 1999, 1998 and 1997 is summarized in the
following table (amounts include deliveries made under the terms of a volumetric
production payment agreement effective from July 1, 1996 to June 30, 1997):


Year Ended December 31,
-----------------------------------------------
1999 1998 1997
----------- ----------- -----------

Natural gas volumes (mmcf) 5,693 6,216 6,926
Average natural gas price ($/mcf) $ 2.28 $ 2.27 $ 2.63
Crude oil/condensate volumes (mbbl) 346 386 420
Average crude oil/condensate price ($/bbl) $ 16.35 $ 11.78 $ 16.83


Oil and gas revenue was $19,036,000, $18,994,000 and $25,680,000 during
1999, 1998 and 1997, respectively. The increase in oil and gas revenue from 1998
to 1999 was primarily attributable to higher average oil prices received by the
Company offset by lower oil and gas production. The decline in oil and gas
production between 1998 and 1999 was primarily due to normal production declines
experienced on several of the Company's older wells. Additionally, in July 1999,
the Company sold its interest in 11 oil and gas wells, five of which were
producing. The decrease in oil and gas revenue from 1997 to 1998 was primarily
due to lower realized commodity prices along with lower natural gas production.
The production decline from several of the Company's shallow short-lived
producing properties had not yet been offset by production from new wells.
Several wells with high initial flow rates experienced production declines
earlier and greater than was expected. Additionally, some development wells were



not drilled in the time frame anticipated by the Company as a result of some of
its partners delaying plans to drill these wells due to lower commodity prices,
reallocation of budget funds and consolidations within the industry.

Depletion of oil and gas properties, excluding the impairment in 1997
discussed below, was $9,093,000, $11,872,000 and $12,666,000 for the years ended
December 31, 1999, 1998 and 1997, respectively, which amounted to $1.17, $1.39
and $1.34, respectively, per mcfe of gas produced during such periods. The rate
per mcfe varies with the estimate of proved oil and gas reserves of the Company
at each quarter end, as well as evaluated property costs.

At December 31, 1997, the Company recorded a non-cash impairment of oil and
gas properties totaling $9,560,000 ($6,160,000, net of taxes) based on its
December 31, 1997, estimated proved reserves valued at March 18, 1998 market
prices. The impairment was primarily due to substantially lower commodity
prices.

Oil and gas production costs amounted to $.61, $.55, and $.55 per mcfe of
gas produced during 1999, 1998 and 1997, respectively. The increase in the rate
from 1998 to 1999 is primarily attributable to an increase in compression costs
for the Company's East Texas Smackover properties.

Geophysical Services

The Company completed an initial public offering of Eagle Geophysical, Inc.
("Eagle"), its former seismic acquisition crew subsidiary, in August 1997.
Consequently, the Company had no operations from geophysical services in 1998 or
1999.

Corporate and Other

The Company's selling, general and administrative expenses were $28,587,000
in 1999, $26,599,000 in 1998 and $23,043,000 in 1997. The increase from 1998 to
1999 was primarily due to legal and other non-recurring expenses incurred during
1999 and an increase in costs resulting from the Company's expansion in Canada.
These increases were partially offset by a reduction of variable expenses,
including commissions on revenue and compensation tied to pre-tax profits. The
increase from 1997 to 1998 was primarily a result of variable expenses,
including commissions on revenue and compensation tied to pre-tax profits,
related to the increased volume of business. As a percentage of total revenue,
these expenses were 22% in 1999 and 18% in 1998 and 1997.

The Company's interest expense was $11,791,000 in 1999, $5,963,000 in 1998
and $4,609,000 in 1997. The increase between 1998 and 1999 was primarily due to
the addition of $138 million of senior notes on February 12, 1999 at an average
interest rate of 7.3% partially offset by lower interest expense on the
Company's revolving line of credit due to lower amounts being borrowed
throughout 1999. The increase from 1997 to 1998 was primarily due to increased
borrowings made under the Company's revolving line of credit during 1998.

Interest income was $714,000 in 1999, $423,000 in 1998 and $1,055,000 in
1997. The increase from 1998 to 1999 was primarily attributable to interest
income received on the notes receivable from officers and employees entered into
in October 1998. The decrease between 1997 to 1998 was primarily due to the
fluctuations in cash balances available for investment.

On August 11, 1997, Eagle completed an initial public offering in which the
Company sold 1,880,000 of its 3,400,000 shares of Eagle common stock as a
selling stockholder. The Company received net proceeds of $29,723,000 from its
participation in the offering, resulting in a pre-tax gain, net of costs, of
$18,449,000 from its sale of Eagle stock in 1997. Additionally, the Company
recorded a pre-tax gain, net of costs, of $10,750,000 in 1997, representing an
increase in the Company's underlying equity of Eagle as a result of Eagle's
issuance of stock in connection with the offering. In 1998, Eagle issued stock
in connection with two acquisitions, which caused the Company to record a
pre-tax loss of $193,000. The Company's equity in earnings (loss) of Eagle was
$146,000 for the period from August 11, 1997 to December 31, 1997, $222,000 for
the year ended December 31, 1998 and $(91,000) for the year ended December 31,
1999.

On April 22, 1999, the Board of Directors of Seitel, Inc. declared to its
common stockholders a dividend consisting of the remaining 1,520,000 shares of
the common stock of Eagle owned by the Company. The fair market value of the
common stock of Eagle held by the Company on the date the dividend was declared
was lower than the carrying value of the stock on the Company's balance sheet;
therefore, a non-cash, non-recurring, pre-tax impairment, net of bonus effect,
of $7,794,000 was recorded for the year ended December 31, 1999.


The Company entered into an agreement, which was effective July 1, 1997, to
extinguish its volumetric production payment. The cost to acquire the production
payment liability exceeded its book value. As a result of this transaction, the
Company recorded a pre-tax loss of $4,133,000 in 1997.

The Company's effective income tax rate on income before provision for
income taxes and special items was 40.6%, 35.9% and 35.5% for the years ended
December 31, 1999, 1998 and 1997, respectively. The increase in the effective
income tax rate from 1998 to 1999 was primarily a result of Canadian operations,
which are taxed at a higher rate than the U.S. rate, representing a larger
percentage of pre-tax profits than in prior years.

Liquidity and Capital Resources

The Company's cash flow from operations was $74,494,000, $97,493,000 and
$76,161,000 for the years ended December 31, 1999, 1998 and 1997, respectively.
The decrease from 1998 to 1999 was primarily attributable to (i) a decrease in
cash received from customers due to the decrease in revenue in 1999, (ii) an
increase in payments to suppliers in 1999 and (iii) an increase in interest
expense paid due to the issuance of $138 million senior notes in 1999. The
increase from 1997 to 1998 was primarily due to (i) an increase in cash received
from customers due to higher revenue in 1998 and (ii) a decrease in cash paid to
suppliers and employees due to lower cost of sales incurred in 1998 resulting
from the 1997 spin-off of the Company's crew subsidiary and increased payable
balances at December 31, 1998.

The Company has a $75 million unsecured revolving line of credit facility
that matures on March 16, 2001. The facility bears interest at a rate determined
by the ratio of the Company's debt to cash flow from operations. Pursuant to the
interest rate pricing structure, funds can currently be borrowed at LIBOR plus 1
1/2%, the bank's prevailing prime rate, or the sum of the Federal Funds
effective rate for such day plus 1/2%. Certain restrictions exist that limit the
amount of borrowing that the Company can make under this facility. The balance
outstanding on the revolving line of credit at March 27, 2000 was $37 million
bearing an average interest rate of 6.89%.

On November 9, 1999, the Company's wholly-owned subsidiary, Olympic Seismic
Ltd. ("Olympic"), entered into revolving credit facilities which allow it to
borrow up to $5 million (Canadian dollars) by way of prime based loans, bankers'
acceptances, or letters of credit. Prime based loans and bankers' acceptances
bear interest at the rate of the bank's prime rate plus 0.35% per annum and
0.50% per annum, respectively. Letter of credit fees are based on scheduled
rates in effect at the time of issuance. The facility is secured by Olympic's
assets, but is not guaranteed by Seitel, Inc. or any of its other subsidiaries.
Borrowings under the facility are limited to 75% of trade receivables less than
90 days old. The facility is subject to repayment upon demand and is available
from time to time at the Bank's sole discretion. Olympic did not have any
amounts outstanding under this line of credit at December 31, 1999, or at March
27, 2000. Olympic is not a party to any of the debt held by Seitel, Inc.

On February 12, 1999, the Company completed a private placement of three
series of unsecured Senior Notes totaling $138 million. The Series D Notes total
$20 million, bear interest at a fixed rate of 7.03% and mature on February 15,
2004, with no principal payments due until maturity. The Series E Notes total
$75 million, bear interest at a fixed rate of 7.28% and mature on February 15,
2009, with annual principal payments of $12.5 million beginning February 15,
2004. The Series F Notes total $43 million, bear interest at a fixed rate of
7.43% and mature on February 15, 2009, with no principal payments due until
maturity. Interest on all series of the notes is payable semi-annually on
February 15 and August 15. The Company used a majority of the proceeds to repay
amounts outstanding under its revolving lines of credit and the remainder for
capital expenditures.

On December 28, 1995, the Company completed a private placement of three
series of unsecured Senior Notes totaling $75 million. The Company
contemporaneously issued its Series A Notes and Series B Notes, which total
$52.5 million and bear interest at a fixed rate of 7.17%. On April 9, 1996, the
Company issued its Series C Notes, which total $22.5 million and bear interest
at a fixed rate of 7.48%. The Series A Notes mature on December 30, 2001, and
require annual principal payments of $8.3 million which began on December 30,
1999. The Series B and Series C Notes mature on December 30, 2002, and require
combined annual principal payments of $10 million which began on December 30,
1998. Interest on all series of the notes is payable semi-annually on June 30
and December 30. As of March 27, 2000, the balance outstanding on the Series A,
B, and C Notes was $46,667,000.

The Company may offer from time to time in one or more series (i) unsecured
debt securities, which may be senior or subordinated, (ii) preferred stock and
(iii) common stock, or any combination of the foregoing, up to an aggregate of
$41,041,600 pursuant to an effective "shelf" registration statement filed with



the SEC. In addition, under another effective "shelf" registration statement
filed with the SEC, the Company may offer up to an aggregate of $200,000,000 of
the following securities, in any combination, from time to time in one or more
series: (i) unsecured debt securities, which may be senior or unsubordinated;
(ii) preferred stock; (iii) common stock, and (iv) trust preferred securities.

From January 1, 1999, through March 27, 2000, the Company received
$5,317,000 from the exercise of common stock purchase warrants and options. In
connection with these exercises, the Company will also receive approximately
$620,000 in tax savings.

On July 26, 1999, the Company's wholly-owned subsidiary, DDD Energy, sold
its 18.75% working interest in 11 oil and gas wells, one salt water disposal
well and approximately 16,000 acres of leasehold and options to lease for net
proceeds of approximately $11.7 million.

In November 1999, the Company's 19% owned subsidiary, Vision Energy, filed
a registration statement with the SEC to accomplish the spin-off of DDD Energy
through an initial public offering. In the proposed offering, Vision Energy
would acquire all of the stock of DDD Energy from the Company in exchange for
the issuance of shares of Vision Energy stock to the Company, and the Company
would sell most of these Vision Energy shares in the public offering for cash.
Completion of the offering is expected to occur during the second or third
quarter of 2000; however, its completion is dependent upon market conditions and
other factors. As of December 31, 1999, the Company had incurred costs relating
to this offering totaling $757,000 which are included in prepaid expenses in the
Company's balance sheet as of December 31, 1999. The Company continues to
explore opportunities to maximize the value of DDD Energy. The Company intends
to use the cash proceeds from this spin-off of DDD Energy to reduce debt and
provide funds for seismic data bank capital expenditures.

During November and December 1999, the Company repurchased 504,700 shares
of its common stock in the open market at a cost of $3,302,000, pursuant to a
stock repurchase program authorized by the Board of Directors in 1997. The Board
has authorized expenditures of up to $25 million towards the repurchase of its
common stock. As of March 27, 2000, the Company has repurchased 679,700 shares
of its common stock at a cost of $6,275,000 under this plan.

During 1999, gross seismic data bank additions and capitalized oil and gas
exploration and development costs amounted to $116,343,000 and $21,939,000
respectively. These capital expenditures, as well as taxes, interest expenses,
cost of sales and general and administrative expenses, were funded by
operations, proceeds from the sale of oil and gas properties, proceeds from the
exercise of common stock purchase warrants and options, borrowings under the
Company's revolving line of credit and proceeds from the issuance of senior
notes.

Currently, the Company anticipates capital expenditures to total
approximately $70 million for seismic data bank additions during fiscal 2000 and
approximately $11 million for oil and gas exploration and development efforts
during the first half of 2000. If the proposed spin-off of DDD Energy has not
been completed by the end of the second quarter, oil and gas exploration and
development capital expenditures are expected to be $9 million for the second
half of 2000. The Company believes its current cash balances, revenues from
operating sources and proceeds from the exercise of common stock purchase
warrants and options, combined with its available revolving line of credit,
should be sufficient to fund the currently anticipated 2000 capital
expenditures, along with expenditures for operating and general and
administrative expenses. If these sources are not sufficient to cover the
Company's anticipated expenditures or if the Company were to increase its
planned capital expenditures for 2000, the Company could arrange for additional
debt or equity financing during 2000; however, there can be no assurance that
the Company would be able to accomplish any such debt or equity financing on
satisfactory terms. If such debt or equity financing is not available on
satisfactory terms, the Company could reduce its current capital budget or any
proposed increases to its capital budget, and fund expenditures with cash flow
generated from operating sources. Upon consummation of the proposed spin-off of
DDD Energy, proceeds from such offering would be used to reduce debt and provide
funds for additional seismic data bank capital expenditures.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133, as
amended by SFAS No. 137, is required to be adopted on January 1, 2001, although
earlier adoption is permitted. 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 formally document, designate, and assess the effectiveness of
transactions that receive hedge accounting treatment. The Company has not yet
quantified the impact of adopting SFAS No. 133. However, management does not
believe that the adoption of SFAS No. 133 will have a material impact on the
Company's financial position or results of operations.

Year 2000

The Company did not experience any significant operational difficulties or
incur any significant expenses in connection with the Year 2000 issue. The
Company will continue to monitor all critical systems for any incidents of
delayed complications or disruptions and problems encountered through third
parties with whom the Company deals so that they may be timely addressed.

Impact of Inflation and Changing Prices

The general availability of seismic equipment and crews and the level of
exploration activity in the oil and gas industry directly affect the cost of
creating seismic data. The pricing of the Company's products and services is
primarily a function of these factors. For these reasons, the Company does not
believe inflationary trends have had any significant impact on its financial
operating results during the three years ended December 31, 1999.

Information Regarding Forward Looking Statements

This Annual Report on Form 10-K includes forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Although the Company believes that its
expectations are based on reasonable assumptions, it can give no assurance that
its goals will be achieved. Important factors that could cause actual results to
differ materially from those in the forward looking statements herein include,
but are not limited to, changes in the exploration budgets of the Company's
seismic data and related services customers, actual customer demand for the
Company's seismic data and related services, the extent of the Company's 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
markets and equity markets during the periods covered by the forward looking
statements. See Item 1 - Business-Risk Factors.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk, including adverse changes in
commodity prices, interest rates and foreign currency exchange rates as
discussed below.

Commodity Price Risk

The Company produces and sells natural gas, crude oil, condensate and
natural gas liquids. The Company currently sells most of its oil and gas
production under price sensitive or market contracts. As a result, the Company's
financial results can be significantly affected as oil and gas prices fluctuate.
The Company has a price risk management program that utilizes derivative
financial instruments, principally natural gas swaps, to reduce the price risks
associated with fluctuations in natural gas prices. However, these contracts
also limit the benefits the Company would realize if prices increase. These
financial instruments are designated as hedges and accounted for on the accrual
basis, recognizing gains and losses in oil and gas production revenues when the
associated production occurs. These contracts usually are placed with major
derivative dealers that the Company believes are minimal credit risks. The
Company defers and recognizes in income the net gains and losses on natural gas
swaps designated as hedges of anticipated transactions, including accrued gains
or losses upon maturity or termination of the contract, when the associated
hedged gas is produced.

During 1998, the Company recognized net hedging gains of $653,000. As of
December 31, 1998, the Company did not have any open commodity price hedges.
During 1999, the Company entered into natural gas swaps in order to hedge a
portion of anticipated natural gas production. During 1999, the Company
recognized net hedging losses of $308,000. As of December 31, 1999, the Company
had open commodity price hedges totaling 2,285,000 MMBtu at an average price of
2.51 per MMBtu. The estimated fair value of these open commodity price hedges as
of December 31, 1999 was $(377,000). The Company continually reviews and may
alter its hedged positions. The Company's strategy is to seek arrangements with
guaranteed minimum prices and flexibility to participate in improving commodity
prices.






As of December 31, 1999, the Company had the following hedges in place:

Volume Per
Month Hedge Price
Month (MMBtu) ($/MMBtu)
- ------------------------------------- --------------- ---------------

January 2000 310,000 $2.51
February 2000 290,000 2.51
March 2000 310,000 2.51
April 2000 300,000 2.51
May 2000 310,000 2.51
June 2000 300,000 2.51
July 2000 310,000 2.51
August 2000 155,000 2.57
---------------

Total volume hedged 2,285,000
===============


Interest Rate Risk

The Company may enter into various financial instruments, such as interest
rate swaps, to manage the impact of changes in interest rates. Currently, the
Company has no open interest rate swap or interest rate lock agreements.
Therefore, the Company's exposure to changes in interest rates primarily results
from its short-term and long-term debt with both fixed and floating interest
rates. The following table presents principal or notional amounts (stated in
thousands) and related average interest rates by year of maturity for the
Company's debt obligations and their indicated fair market value at December 31,
1999:

Average Interest Rate 7.25% 7.25% 7.25% 7.31% 7.26% -


Foreign Currency Exchange Rate Risk

The Company conducts business in the Canadian dollar and pounds sterling
and is therefore 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 Canada, where the Company's
functional currency is the Canadian dollar, and in the Cayman Islands, where the
Company's functional currency is pounds sterling, is not material at this time.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Seitel, Inc.:

We have audited the accompanying consolidated balance sheets of Seitel, Inc. (a
Delaware corporation) and subsidiaries as of December 31, 1999 and 1998, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Seitel, Inc. and subsidiaries
as of December 31, 1999 and 1998, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.

SEITEL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1999

NOTE A--SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations: Seitel, Inc. (the "Company") is a leading
diversified energy company providing seismic data and related geophysical
services to the oil and gas industry and directly participating in exploration,
development and ownership of natural gas and crude oil reserves. The majority of
the Company's seismic surveys cover onshore and offshore the U.S. Gulf Coast
region. The Company's oil and gas exploration, development and production
activities are on properties located primarily in the onshore Gulf Coast areas
of Texas, Louisiana, Alabama and Mississippi, as well as California and
Arkansas.

In the course of its operations, the Company is subject to certain risk
factors, including, but not limited to, the following: competition, industry
conditions, volatility of oil and gas prices, operating risks, dependence of key
personnel, geographic concentration of operations and compliance with
governmental regulations.

Use of Estimates: The preparation of these consolidated financial
statements in conformity with accounting principles generally accepted in the
United States requires the use of certain estimates by management in determining
the Company's assets, liabilities, revenues and expenses. Actual results could
differ from estimates. Data bank amortization is determined using estimates of
ultimate revenues from licensing of the seismic data. Refer to the data bank
discussion below for additional information on data bank amortization.
Depreciation, depletion and amortization of oil and gas properties and the
impairment of oil and gas properties are determined using estimates of proved
oil and gas reserves and the present value of estimated cash flows therefrom.
There are numerous uncertainties in estimating the quantity of proved reserves
and in projecting the future rates of production and timing of development
expenditures. Refer to Note S, "Supplemental Oil and Gas Information" for
additional information regarding the process of estimating proved oil and gas
reserve quantities and related values.

Basis of Presentation: The accompanying consolidated financial
statements include the accounts of Seitel, Inc., the accounts of its
wholly-owned subsidiaries and the Company's pro rata share of its investments in
joint ventures. Investments in less than majority owned companies over which the
Company has the ability to exercise significant influence are accounted for
using the equity method. All material intercompany accounts and transactions
have been eliminated in consolidation. Certain reclassifications have been made
to the amounts in the prior years' financial statements to conform to the
current year's presentation.

The Company presents its consolidated balance sheets on an unclassified
basis. Because the portion of seismic data acquisition costs to be amortized
during the next year cannot be classified as a current asset, and classification
of all of these costs as noncurrent would be misleading to the reader because it
would not indicate the level of assets expected to be converted into cash in the
next year, the Company believes that the use of an unclassified balance sheet
results in improved financial reporting.

Data Bank: Costs incurred in the creation of proprietary seismic data,
including the direct and incremental costs of Company personnel engaged in
project management and design, are capitalized. Substantially all (greater than
88%) of the costs incurred to develop the Company's data bank have been for
programs created by the Company. The Company uses the income forecast method to
amortize the costs of seismic data programs it creates. Under the income
forecast method, seismic data costs are amortized in the proportion that revenue
for a period relates to management's estimate of ultimate revenues. Management
estimates that 90% of the costs incurred in the creation of seismic data is
amortized within five years of such data becoming available for resale for
two-dimensional seismic data and within seven years of such data becoming
available for resale for three-dimensional seismic data. If anticipated sales
fall below expectations, amortization is accelerated. The Company also purchases
existing seismic data programs from other companies. The costs of purchased
seismic data programs are generally amortized on a straight-line basis over ten
years; however, the costs of a significant purchase (greater than 5% of the net
book value of the data bank), are amortized using the greater of the income
forecast method or ten-year straight-line method. As of December 31, 1999,
almost all (97%) of the net costs of the Company's data bank are expected to be
fully amortized within 10 years from when such data becomes available for
resale. On a periodic basis, the carrying value of seismic data is compared to



F-8





its estimated future revenue and, if appropriate, is reduced to its estimated
net realizable value. Net data bank at December 31, 1999 and 1998 was comprised
of the following (in thousands):

------------ ------------
Net data bank $ 329,885 $ 262,950
============ ============


Oil and Gas Properties: The Company accounts for its oil and gas
exploration and production activities using the full-cost method of accounting.
Under this method, all costs associated with acquisition, exploration and
development of oil and gas reserves are capitalized, including salaries,
benefits and other internal costs, directly attributable to these activities.
Costs associated with production and general corporate activities are expensed
in the period incurred. For the years ended December 31, 1999, 1998 and 1997,
exploration and development related overhead costs of $1,938,000, $1,795,000 and
$1,431,000, respectively, have been capitalized to oil and gas properties.
Interest costs related to unproved properties and certain properties under
development are also capitalized to oil and gas properties. For the years ended
December 31, 1999, 1998 and 1997, interest costs of $3,101,000, $2,486,000 and
$2,105,000, respectively, have been capitalized to oil and gas properties.

No gains or losses are recognized upon the sale of oil and gas
properties unless a significant portion of the Company's proved oil and gas
reserves are sold (generally greater than 25 percent). Instead, proceeds from
the sale of oil and gas properties are accounted for as a reduction of
capitalized costs. In July 1999, the Company sold its 18.75% working interest in
11 oil and gas wells, one salt water disposal well and approximately 16,000
acres of leasehold and options to lease for approximately $11.7 million, net of
costs.

Depreciation, depletion and amortization ("DD&A") expense is calculated
quarterly using the units-of-production method based upon production and
estimates of proved reserves. Estimated future development costs and site
restoration, dismantlement and abandonment costs, net of salvage values, are
included in the amortization base. Capitalized costs associated with the
acquisition and evaluation of unproved properties and certain properties under
development are not included in the amortization base until the properties
associated with these costs are evaluated.

Capitalized costs of oil and gas properties, net of accumulated DD&A
and deferred income taxes, are limited to the present value, discounted at 10
percent, of future net cash flows from estimated proved oil and gas reserves,
based on current economic and operating conditions, plus the lower of cost or
fair value of unproved properties, adjusted for the effects of related income
taxes. If capitalized costs exceed this limit, the excess is charged to
impairment of oil and gas properties. Based on the Company's December 31, 1997
estimated proved reserves valued at March 18, 1998 market prices, the Company
recorded a non-cash impairment of oil and gas properties of $9,560,000
($6,160,000 net of taxes) in 1997. At March 31, 1999, the Company's capitalized
costs of oil and gas properties exceeded the limitation thereon based on
quarter-end oil and gas prices; however, an impairment was not recorded at that
time because price increases in April 1999 indicated that capitalized costs were
not impaired. Given the volatility of oil and gas prices, it is reasonably
possible that the Company's estimate of discounted future net cash flows from
proved oil and gas reserves could change in the near term. If oil and gas prices
decline significantly in the future, even if only for a short period of time, it
is possible that additional impairments of oil and gas properties could occur.

Substantially all of the Company's exploration and development
activities are conducted jointly with others and, accordingly, the Company's oil
and gas property balance reflects only its proportionate interest in such
activities.

Other Property and Equipment: Depreciation of other property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets of three to five years.

Marketable Equity Securities: The Company accounts for its marketable
equity securities in accordance with Statement of Financial Accounting Standards
("SFAS") No. 115, "Accounting for Certain Investments in Debt and Equity
Securities." Management determines the appropriate classification of marketable
securities at the time of purchase and reevaluates such designation at each
balance sheet date. The Company's marketable securities are categorized as
available-for-sale and are carried at fair value, with unrealized holding
F-9


gains and losses, net of taxes, reflected in accumulated other comprehensive
income (loss) included in stockholders' equity until realized. For the purpose
of computing realized gains and losses, cost is identified on a specific
identification basis.

At December 31, 1999, unrealized losses on marketable securities were
$1,571,000. The deferred tax benefit on this loss was $526,000 at December 31,
1999, resulting in a net charge of $1,045,000 to other comprehensive income.

Debt Issue Costs: Debt issue costs related to the Company's Senior
Notes and line of credit are included in prepaid expenses, deferred charges and
other assets in the consolidated balance sheet. Such costs are amortized over
the scheduled maturities of the debt. As of December 31, 1999 and 1998,
unamortized debt issue costs were $1,762,000 and $532,000, respectively.

Income Taxes: The Company and all of its U.S. subsidiaries file
a consolidated federal income tax return. The Company does not provide U.S.
taxes on the undistributed earnings of its foreign subsidiaries whose earnings
are intended to be permanently reinvested in foreign operations. At December 31,
1999, accumulated net earnings of non-U.S. subsidiaries for which no U.S.
federal taxes have been provided were $6,609,000.

Income Recognition: Revenue from seismic data licensing agreements is
recognized when each seismic data program is available for use by the licensees,
and is presented net of revenue shared with other entities. Revenue from the
acquisition of seismic data for non-affiliated parties is recognized on the
percentage-of-completion method based on the work effort completed compared with
the total work effort estimated for the contract. These contracts generally
provide that the customer accepts work completed throughout the performance
period and owes the Company, based on pricing provisions, amounts for job
completion, measured in terms of performance progress. Revenue received in
advance of being earned is deferred until earned.

In certain cases, the Company grants seismic licenses to third parties
for data to be used in their operations (not for resale) in exchange for
exclusive ownership of seismic data from the third party. The Company recognizes
revenue for the licenses granted and records a data library asset for the
seismic data acquired. These transactions are accounted for as non-monetary
exchanges and are valued at the fair market value of such licenses based on
values realized in cash transactions with other parties for similar seismic
data.

Cost of Sales: Cost of sales consists of expenses associated with oil
and gas production, seismic resale support services and the acquisition of
seismic data for non-affiliated parties (until August 11, 1997). The cost of
acquiring seismic data for non-affiliated parties includes all direct material
and labor costs and indirect costs related to the acquisition such as supplies,
tools, repairs and depreciation.

Foreign Currency Translation: For subsidiaries whose functional
currency is deemed to be other than the U.S. dollar, asset and liability
accounts are translated at period-end exchange rates and revenue and expenses
are translated at the current exchange rates as of the dates on which they are
recognized. Resulting translation adjustments are included in accumulated other
comprehensive income (loss) in stockholders' equity. Any gains or losses
realized on transactions or monetary assets or liabilities in currencies other
than the functional currency are included in net income in the current period.
Transaction gains (losses) totaling $455,000, $108,000 and $(87,000) for the
years ended December 31, 1999, 1998 and 1997, respectively, are included in
selling general and administrative expenses in the consolidated statements of
operations.

Use of Derivatives: The Company has a price risk management program
that utilizes derivative financial instruments, principally natural gas swaps,
to reduce the price risks associated with fluctuations in natural gas prices.
Such contracts usually are placed with major derivative dealers that the Company
believes are minimal credit risks. The Company accounts for its derivative
financial instruments using the hedge (or deferral) method of accounting. Under
this method, realized gains and losses from the Company's price risk management
activities are recognized in oil and gas production revenues when the associated
production occurs and the resulting cash flows are reported as cash flows from
operating activities. Gains and losses on derivative financial instruments that
are closed before the hedged production occurs are deferred until the production
month originally hedged.





F-10


In June 1998, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities."
SFAS No. 133, as amended by SFAS No. 137, is required to be adopted on January
1, 2001, although earlier adoption is permitted. 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 formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting treatment. The
Company has not yet quantified the impact of adopting SFAS No. 133. However,
management does not believe that the adoption of SFAS No. 133 will have a
material impact on the Company's financial position or results of operations.

Earnings per Share: In accordance with SFAS No. 128, "Earnings Per
Share," basic earnings per share is computed based on the weighted average
shares of common stock outstanding during the periods. Diluted earnings per
share is computed based on the weighted average shares of common stock plus the
assumed issuance of common stock for all potentially dilutive securities.
Earnings per share computations to reconcile basic and diluted net income for
the years 1999, 1998 and 1997 consist of the following (in thousands except per
share amounts):

purchase 5,517,000, 187,000 and 1,007,000 shares of common stock were
outstanding during 1999, 1998 and 1997, respectively, but were not
included in the computation of diluted per share net income because
their exercise prices were greater than the average market price of the
common shares.



Stock-Based Compensation: The Company accounts for employee stock-based
compensation using the intrinsic value method prescribed by Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees." Reference is made to Note H, "Stock Options and Warrants," for a
summary of the pro forma effect of SFAS No. 123, "Accounting for Stock-Based
Compensation" on the Company's results of operations in 1999, 1998 and 1997.

Fair Value of Financial Instruments: SFAS No. 107, "Disclosures about
Fair Value of Financial Instruments," requires disclosure of the fair value of
certain financial instruments. The estimated fair value amounts have been
determined by the Company using available market data and valuation
methodologies. The book values of cash and equivalents, receivables and accounts
payable approximate their fair value as of December 31, 1999 and 1998, because
of the short-term maturity of these instruments. Based upon the rates available
to the Company, the fair value of the Senior Notes and the term loans
approximates $182,656,000 and $65,149,000 as of December 31, 1999 and 1998,
respectively. The book value of the Company's revolving line of credit
approximates fair value due to the variable interest rates under the line.

Impairment of Long-Lived Assets: In accordance with SFAS No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed Of," the Company reviews long-lived assets for impairment whenever
events or changes in circumstances indicate that the carrying value of an asset
may not be realizable. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if an impairment of such asset is necessary. The
effect of any impairment would be to expense the difference between the fair
value of such asset and its carrying value. There were no such impairments
recorded under SFAS No. 121 in 1999, 1998 or 1997.

Accounting For Sales of Stock By Subsidiary Companies: The Company
recognizes gains or losses on sales of stock by its subsidiary companies when
such sales are not made as part of a larger plan of corporate reorganization.
Such gains or losses are based upon the difference between the book value of the
Company's investment in the subsidiary immediately after the sale and the
historical book value of the Company's investment immediately prior to the sale.

Comprehensive Income: In accordance with SFAS No. 130, "Reporting
Comprehensive Income," the Company has reported comprehensive income in the
consolidated statements of stockholders' equity for the three years ended
December 31, 1999. Accumulated other comprehensive income for the Company
consists of foreign currency translation adjustments and unrealized gains
(losses) on marketable securities. Cumulative translation adjustments are not
adjusted for income taxes as they relate to indefinite investments in non-U.S.
subsidiaries.

offset regular Federal income taxes payable in future years. The AMT credit has
an indefinite carryforward period.

In connection with the exercise of non-qualified stock options and
common stock purchase warrants by employees during 1999, 1998 and 1997, the
Company received $597,000, $344,000 and $5,657,000, respectively, in Federal
income tax savings which has been reflected as a credit to additional paid-in
capital.

$ 225,200 $ 150,672
========== ==========


Senior Notes: The Company has issued six series of unsecured Senior
Notes totaling $213 million through private placement. Interest on the Series
A, B and C Senior Notes is payable semi-annually on June 30 and December 30 and
interest on the Series D, E and F Senior Notes is payable semi-annually on
February 15 and August 15. Accrued interest of $3,735,000 is included in accrued
liabilities at December 31, 1999. At December 31, 1998, the Company did not have
any accrued interest on the Senior Notes.

Lines of Credit: The Company has a $75 million unsecured revolving line
of credit facility that matures on March 16, 2001. The facility bears interest
at a rate determined by the ratio of the Company's debt to cash flow from
operations. Pursuant to the interest rate pricing structure, funds can currently
be borrowed at LIBOR plus 1 1/2%, the bank's prevailing prime rate, or the sum
of the Federal Funds effective rate for such day plus 1/2%. Certain restrictions
exist that limit the amount of borrowings that the Company can make under the
credit facility.

In February 1999, the Company paid all amounts outstanding under a $25
million line of credit and cancelled the line of credit.

On November 9, 1999, the Company's wholly-owned subsidiary, Olympic
Seismic Ltd. ("Olympic"), entered into revolving credit facilities which allow
it to borrow up to $5 million (Canadian dollars) by way of prime based loans,
bankers' acceptances or letters of credit. Prime based loans and bankers'
acceptances bear interest at the rate of the bank's prime rate plus 0.35% per
annum and 0.50% per annum, respectively. Letter of credit fees are based on
scheduled rates in effect at the time of issuance. The facility is secured by
Olympic's assets, but is not guaranteed by Seitel, Inc. or any of its other
subsidiaries. Borrowings under the facility are limited to 75% of trade
receivables less than 90 days old. The facility is subject to repayment upon
demand and is available from time to time at the Bank's sole discretion. Olympic
did not have any amounts outstanding under this line of credit at December 31,
1999.

The financial covenant restrictions for the Senior Notes and line of
credit include, among others, interest coverage, maintenance of minimum net
worth and limitations on liens, total debt, debt issuance and disposition of
assets. The Company was in compliance with the financial convenants at December
31, 1999.

Aggregate maturities of the Company's debt over the next five years and
thereafter are as follows: $18,367,000 in 2000; $58,833,000 in 2001; $10,000,000
in 2002, $0 in 2003, $32,500,000 in 2004 and $105,500,000 thereafter.

The Company leases office space under operating leases. Rental expense
for 1999, 1998 and 1997 was approximately $1,112,000, $757,000 and $606,000,
respectively.

NOTE E--VOLUMETRIC PRODUCTION PAYMENT

In June 1996, the Company sold a volumetric production payment for $19
million to certain limited partnerships. Under the terms of the production
payment agreements, the Company conveyed a mineral property interest of
approximately 7.6 billion cubic feet of certain natural gas and approximately
363,000 barrels of other hydrocarbons to the purchasers. The Company retained
responsibility for its working interest share of the cost of operations. The
Company accounted for the proceeds received in the transaction as deferred
revenue which was amortized into revenue and income as natural gas and other
hydrocarbons were produced and delivered.

The Company entered into an agreement to extinguish the remaining
portion of its volumetric production payment which was effective July 1, 1997.
The cost to acquire the production payment liability exceeded its book value. As
a result of this transaction, the Company recorded a pre-tax loss of $4,133,000
in the accompanying consolidated statement of operations for the year ended
December 31, 1997.

NOTE F--CONTINGENCIES AND COMMITMENTS

At both December 31, 1999 and 1998, $274,000 of charges for seismic
surveys which are payable to joint venture partners only from the collection of
sales proceeds from those seismic surveys are included in contingent payables.

The Company has employment agreements with certain of its key employees
and other incentive compensation arrangements that commit it to commissions
based on revenue, bonuses based on pre-tax profits, and other amounts based on
seismic data program and oil and gas project profitability. Part III of the
Company's Form 10-K contains a more complete discussion of these contractual
obligations.

The Company guarantees borrowings up to $750,000 made by its president
under a line of credit. The Company is only obligated to make payment in the
event of default by its president. The Company has a contractual right of offset
against any salary, bonus, commission or other amounts due from the Company to
its president for any amounts paid by the Company pursuant to this guaranty. At
December 31, 1999, $700,000 was outstanding on this line of credit, which
represented the maximum amount outstanding on this line of credit for the year.
The Company did not make any payments under this guaranty during 1999.

The Company is involved from time to time in or threatened with
litigation and is subject to governmental and regulatory controls arising in the
ordinary course of business. It is the opinion of the Company's management that
all claims and litigation involving the Company are not likely to have a
material adverse effect on its financial position or results of operations.

F-15


The Company, as an owner of oil and gas properties, is subject to
various federal, state and local laws and regulations relating to discharge of
materials into, and protection of, the environment. These laws and regulations
may, among other things, impose liability on the lessee under an oil and gas
lease for the cost of pollution clean-up resulting from operations and subject
the lessee to liability for pollution damages. The Company maintains insurance
coverage, which it believes is customary in the industry, although it is not
fully insured against all environmental risks. The Company is not aware of any
environmental claims existing as of December 31, 1999, which would have a
material impact on its financial position or results of operations.

NOTE G--FINANCIAL INSTRUMENTS AND OFF-BALANCE-SHEET RISK

The Company has a price risk management program that utilizes
derivative financial instruments, principally natural gas swaps, to reduce the
price risk associated with fluctuations in natural gas prices. Such contracts
usually are placed with major derivative dealers that the Company believes are
minimal credit risks. The derivative financial instruments call for the Company
to receive or make payments based upon the differential between a fixed and a
variable commodity price as specified in the contract. As a result of these
activities, the Company recognized net hedging gains (losses) of $(308,000),
$653,000 and $474,000 for the years ended December 31, 1999, 1998 and 1997,
respectively.

As of December 31, 1999, the Company had open natural gas swaps through
July 2000 covering 10,000 MMBtu per day at a fixed price of $2.51 per MMBtu and
for August 2000 covering 5,000 MMBtu per day at a fixed price of $2.57 per
MMBtu.

The estimated fair value of open commodity price hedges as of December
31, 1999 and December 31, 1997 was $(377,000) and $183,000, respectively. As of
December 31, 1998, the Company did not have any open commodity price hedges.

NOTE H--STOCK OPTIONS AND WARRANTS

The Company presently maintains four stock option plans under which the
Company's officers, directors and employees may be granted options or warrants
to purchase the Company's common stock. The exercise price, term and other
conditions applicable to each option or warrant granted under the Company's
plans are generally determined by the Compensation Committee at the time of
grant and may vary with each option or warrant granted. All options and warrants
issued under the Company's plans are issued at or above the market price of the
Company's common stock as of the date of issuance, have a term of no more than
ten years and vest under varying schedules in accordance with the terms of the
respective option or warrant agreements.

The following summarizes information with regard to the stock option
and warrant plans for the years ended December 31, 1999, 1998 and 1997 (shares

The Company applies APB Opinion No. 25 and related interpretations in
accounting for its stock-based compensation plans. APB Opinion No. 25 generally
does not require compensation costs to be recorded on options which have
exercise prices at least equal to the market price of the stock on the date of
grant. Accordingly, no compensation cost has been recognized for the Company's
stock-based plans. Had compensation cost for the Company's stock-based
compensation plans been determined based on the fair value at the grant dates
for awards under those plans consistent with the optional accounting method
prescribed by SFAS No. 123, "Accounting for Stock-Based Compensation," the
Company's net income and earnings per share would have been reduced to the pro
forma amounts indicated below (in thousands, except per share data):


1999 1998 1997
---------- ---------- ----------


Net income As reported $ 9,380 $ 24,360 $ 31,557
Pro forma $ 5,331 $ 15,159 $ 17,039

Basic earnings per share As reported $ .39 $ 1.07 $ 1.48
Pro forma $ .22 $ .67 $ .80

Diluted earnings per share As reported $ .39 $ 1.05 $ 1.43
Pro forma $ .22 $ .66 $ .78


The fair value of each option grant was estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions for
1999, 1998 and 1997, respectively: (1) risk-free interest rates ranging from
5.56% to 6.73%, 4.44% to 5.03% and 5.79% to 6.79%; (2) dividend yield of 0%, 0%
and 0%; (3) stock price volatility ranging from 47.84% to 482.90%, 44.34% to
57.10% and 37.23% to 45.77%, and (4) expected option lives ranging from .67 to
10 years, .42 to 10 years and 1.67 to 10 years. The weighted-average fair value
of options granted during 1999, 1998 and 1997 was $12.57, $11.94 and $9.98 per
option, respectively, for options granted at fair market value and $7.13, $13.75
and $10.15 per option for options granted above fair market value in 1999, 1998
and 1997, respectively. The pro forma amounts shown above may not be
representative of future results because the SFAS No. 123 method of accounting
has not been applied to options granted prior to January 1, 1995.

NOTE I--NON-EMPLOYEE DIRECTORS' PLANS

The Company has a Non-Employee Directors' Deferred Compensation Plan
which permits each non-employee director to elect to receive annual director
fees in the form of stock options and to defer receipt of any director fees in a
deferred cash account or as deferred shares. As of December 31, 1999, 60,000
shares have been reserved for issuance under this plan and directors have
accumulated 7,067 deferred shares in their accounts of which 656 shares have
been distributed and 6,411 will be distributed in future years.

In 1999, the Company's Board of Directors adopted the Non-Employee
Directors' Retirement Plan which provides that each non-employee director with
10 or more years continuous service is eligible to receive a retirement benefit
based on a formula defined in the plan. In 1999, the Company expensed $18,000
related to this plan.


F-17


NOTE J--COMMON STOCK

On November 20, 1997, the shareholders of the Company approved an
increase in the Company's authorized common stock to 50,000,000 shares to
facilitate a two-for-one stock split, effected in the form of a 100% stock
dividend, which was approved by the Board of Directors on October 7, 1997. The
two-for-one stock split was paid in the form of a stock dividend to shareholders
of record as of December 3, 1997. All numbers of shares and per share amounts in
the accompanying consolidated financial statements and footnotes have been
restated to give effect to the two-for-one stock split except where noted.

In December 1997, the Company's Board of Directors approved the
expenditure of up to $25 million to repurchase the Company's common stock. As of
December 31, 1999, the Company has repurchased 679,700 shares of common stock at
a cost of $6,275,000 under this plan.

The Company may offer from time to time in one or more series (i)
unsecured debt securities, which may be senior or subordinated, (ii) preferred
stock and (iii) common stock or any combination of the foregoing, up to an
aggregate of $41,041,600 pursuant to an effective "shelf" registration statement
filed with the Securities and Exchange Commission ("SEC"). In addition, under
another effective "shelf" registration statement filed with the SEC, the Company
may offer up to an aggregate of $200,000,000 of the following securities, in any
combination, from time to time in one or more series: (1) unsecured debt
securities, which may be senior or subordinated; (2) preferred stock; (3) common
stock, and (4) trust preferred securities.

On July 21, 1992, the Company granted ten-year loans at an interest
rate of 4% to most of its employees for the purchase of 800,000 shares of the
Company's common stock at the then market price of $2.69 per share. Payment of
5% of the original principal balance plus accrued interest are due annually
August 1, with a balloon payment of the remaining principal and interest due
August 1, 2002. On October 2, 1998, the Company granted five-year loans at an
interest rate of 4% to most of its employees for the purchase of 794,300 shares
of the Company's common stock at the then market price of $10.31 per share.
Payment of 60% of the loan amount plus accrued interest is being made in equal
monthly, quarterly or annual payments, as applicable, and a balloon payment of
the remaining 40% is due on October 2, 2003. The Company recorded related
compensation expense due to the below market interest rate on these loans of
$114,000, $54,000 and $43,000 for the years ended December 31, 1999, 1998 and
1997, respectively. During 1999, 1998 and 1997, the Company received $1,736,000,
$649,000 and $96,000, respectively, as principal payments on these notes. The
stock certificates are held by the Company as collateral until payment is
received.

NOTE K--PREFERRED STOCK

The Company is authorized by its Amended Certificate of Incorporation
to issue 5,000,000 shares of preferred stock, the terms and conditions to be
determined by the Board of Directors in creating any particular series. As of
December 31, 1999, no preferred stock had been issued.

NOTE L--INVESTMENT IN EAGLE GEOPHYSICAL, INC.

On August 11, 1997, the Company's wholly-owned seismic data acquisition
crew subsidiary, Eagle Geophysical, Inc. ("Eagle"), completed an initial public
offering ("Offering") in which the Company sold 1,880,000 of its 3,400,000
shares of Eagle common stock as a selling stockholder. The Company received net
proceeds of $29,723,000 from its participation in the Offering, resulting in a
pre-tax gain, net of costs of $18,449,000 on the sale of Eagle common stock in
1997. Additionally, the Company recorded a pre-tax gain, net of costs, of
$10,750,000 in 1997 representing an increase in the Company's underlying equity
of Eagle as a result of Eagle's issuance of stock in connection with the
Offering.

In 1998, Eagle issued stock in connection with two acquisitions which
caused the Company to record a pre-tax loss of $193,000 for the year ended
December 31, 1998.

On April 22, 1999, the Board of Directors of Seitel, Inc. declared to
its common stockholders a dividend consisting of the remaining 1,520,000 shares
of the common stock of Eagle owned by the Company. The dividend was declared at
the rate of approximately 0.064 shares of Eagle common stock for each share of
Seitel, Inc. common stock owned as of the close of business on the record date
of May 18, 1999. The fair market value of the common stock of Eagle held by the
Company on the date this dividend was declared was lower than the carrying value
of the stock on the Company's balance sheet; therefore, a non-cash,
non-recurring, pre-tax impairment, net of bonus effect, of $7,794,000 was
recorded for the year ended December 31, 1999.

NOTE M--RELATED PARTY TRANSACTIONS

The Company periodically uses the seismic data acquisition services of
Eagle. The Company incurred charges of $27,385,000, $79,900,000 and $22,200,000
for these services for the four months ended April 30, 1999, for the year ended
December 31, 1998 and from the period August 11, 1997 through December 31, 1997,
respectively.

The Company owed Helm Resources, Inc. and its subsidiaries ("Helm"), a
company that has three executive officers who are directors of the Company,
$2,000 as of December 31, 1999 and 1998 for sales of seismic data they jointly
own and for general and administrative expenses paid by Helm on behalf of the
Company. The Company incurred charges of $115,000, $99,000 and $76,000, for
these general and administrative expenses during 1999, 1998 and 1997,
respectively. Management believes that these expenses, which were specifically
related to the Company's business, represented costs which would have been
incurred in similar amounts by the Company if such services that were performed
by Helm were performed by an unaffiliated entity.

Certain employees and directors of the Company contributed cash to
partnerships in 1994 through 1997 which invested in the exploration and
development of oil and gas properties on a working interest basis along with DDD
Energy, Inc. ("DDD Energy"). Each partnership's working interest amounted to
2.5% of the total investment made by such partnership and DDD Energy for the
partnership formed in 1997, 3% for the partnership formed in 1996 and 5% for the
partnerships formed in 1995 and 1994. On October 1, 1998, DDD Energy purchased
the oil and gas interests owned by each of the partnerships in exchange for
355,733 shares of the Company's common stock, payment of $824,000 and assumption
of each partnership's liabilities totaling $1,555,000.

NOTE N--MAJOR CUSTOMERS

No customers accounted for 10% or more of revenues during the years
1999, 1998 or 1997.

The Company extends credit to various companies in the oil and gas
industry for the purchase of their seismic data, which results in a
concentration of credit risk. This concentration of credit risk may be affected
by changes in economic or other conditions and may accordingly impact the
Company's overall credit risk. However, management believes that the risk is
mitigated by the number, size, reputation and diversified nature of the
companies to which they extend credit. Historical credit losses incurred on
receivables by the Company have been immaterial.

NOTE O--STATEMENT OF CASH FLOW INFORMATION

For purposes of the statement of cash flows, the Company considers all
highly liquid investments or debt instruments with original maturity of three
months or less to be cash equivalents.

Operating cash flows reported in the consolidated statements of cash
flows do not reflect effects of changes in inventory levels because the Company
reports no inventories and classifies cash expenditures for its seismic data
library as an investing, rather than an operating, activity.

Significant non-cash investing and financing activities are as follows:

1. During 1999, the Company declared to its common stockholders a
dividend consisting of the remaining 1,520,000 shares of
common stock of Eagle owned by the Company with a fair market
value of $6,365,000.

2. During 1999 and 1997, capital lease obligations totaling
$33,000 and $374,000, respectively, were incurred when the
Company entered into leases for property and equipment.

3. During 1998, the Company issued 355,733 shares of its common
stock valued at $3,914,000 to acquire interests in certain oil
and gas properties and assumed liabilities totaling
$1,555,000.

4. During 1998, the Company issued 794,300 shares of its common
stock to its officers and employees in exchange for notes
receivable of $8,191,000.

NOTE P--INDUSTRY SEGMENTS

The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" in 1998. SFAS No. 131 establishes standards
for reporting information about operating segments in annual financial
statements and requires selected information about operating segments in interim
financial reports.

The Company operates in two reportable segments - seismic and
exploration and production. In 1997, the Company had an additional reporting
segment - geophysical services. The long-term financial performance of each of
the reportable segments is affected by similar economic conditions. The
accounting policies of the segments are the same as those described in Footnote
A to these consolidated financial statements. Intersegment sales are accounted
for at prices comparable to those received from unaffiliated customers. The
Company evaluates performance of each reportable segment based on operating
income (loss) before selling, general and administrative expenses, interest
income and expense, income taxes, non-recurring items and accounting changes.

Financial information by reportable segment for the three years ended
December 31, 1999, was as follows (in thousands):

NOTE R--PROPOSED SALE OF OIL AND GAS SUBSIDIARY

In November 1999, the Company's 19% owned subsidiary, Vision Energy,
Inc. ("Vision Energy"), filed a registration statement with the SEC to
accomplish the spin-off of DDD Energy, a wholly-owned subsidiary, through an
initial public offering. In the proposed offering, Vision Energy would acquire
all of the stock of DDD Energy from the Company in exchange for the issuance of
shares of Vision Energy stock to the Company, and the Company would sell most of
these Vision Energy shares in the public offering for cash. Completion of the
offering is expected to occur during the second or third quarter of 2000;
however, its completion is dependent upon market conditions and other factors.
The Company continues to explore opportunities to maximize the value of DDD
Energy. In the event the sale is not completed, DDD Energy will continue to be a
wholly-owned subsidiary of the Company. The Company does not anticipate a loss
will be incurred on this transaction.

As of December 31, 1999, the Company had incurred costs totaling
$757,000 in connection with the proposed initial public offering. The costs have
been included in prepaid expenses, deferred charges and other assets in the
consolidated balance sheet as of December 31, 1999. If the offering is
completed, the costs will be deducted from the proceeds received from the
offering. If the offering is not completed, the costs will be charged to expense
in the period a decision is made to terminate the offering.

NOTE S--SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)

The following information concerning the Company's oil and gas
operations is presented in accordance with SFAS No. 69, "Disclosures about Oil
and Gas Producing Activities."


F-22





Oil and Gas Reserves: Proved oil and gas reserves represent estimated
quantities of natural gas, crude oil, condensate and natural gas liquids that
geological and engineering data demonstrate, with reasonable certainty, to be
recoverable in future years from known reservoirs under economic and operating
conditions existing at the time the estimates were made. Proved developed
reserves are proved reserves expected to be recovered through wells and
equipment in place and under operating methods being utilized at the time the
estimates were made.

The following table sets forth estimates of proved reserves and proved
developed reserves of natural gas and crude oil (including condensate and
natural gas liquids) attributable to the Company's interest in oil and gas
properties. The reserve estimates presented herein were prepared by the
independent petroleum engineering firms of Garb Grubbs Harris & Associates, Inc.
(formerly Forrest A. Garb & Associates, Inc.) at December 31, 1999 and 1998, and
Miller and Lents, Ltd. and Garb Grubbs Harris & Associates, Inc. at December 31,
1997 in accordance with guidelines established by the SEC. It should be noted
that these reserve quantities are estimates and may be subject to substantial
upward or downward revisions. The estimates are based on the most current and
reliable information available; however, additional information obtained through
future production and experience and additional development of existing
reservoirs may significantly alter previous estimates of proved reserves.

and $14,000, respectively, for the year ended December 31, 1999, $331,000 and
$10,000, respectively, for the year ended December 31, 1998 and $398,000 and
$13,000, respectively, for the year ended December 31, 1997.

Standardized Measure of Discounted Future Net Cash Flows Relating to
Proved Oil and Gas Reserves: The following table sets forth the standardized
measure of the discounted future net cash flows attributable to the Company's
proved oil and gas reserves as prescribed by SFAS No. 69. Future cash inflows
were computed by applying year-end prices of oil and gas to the estimated future
production of proved oil and gas reserves. Future prices actually received may
differ from the estimates in the standardized measure.





F-24


Future production and development costs represent the estimated future
expenditures (based on current costs) to be incurred in developing and producing
the proved reserves, assuming continuation of existing economic conditions.
Future income tax expenses were computed by applying statutory income tax rates
to the difference between pre-tax net cash flows relating to the Company's
proved oil and gas reserves and the tax basis of proved oil and gas properties,
adjusted for tax credits and allowances. The resulting annual net cash flows
were then discounted to present value amounts by applying a 10 percent annual
discount factor.

Although the information presented is based on the Company's best
estimates of the required data, the methods and assumptions used in preparing
the data were those prescribed by the FASB. Although not market sensitive, they
were specified in order to achieve uniformity in assumptions and to provide for
the use of reasonably objective data. It is important to note here that this
information is neither fair market value nor the present value of future cash
flows and it does not reflect changes in oil and gas prices experienced since
the respective year-end. It is primarily a tool designed by the FASB to allow
for a reasonable comparison of oil and gas reserves and changes therein through
the use of a standardized method. Accordingly, the Company cautions that this
data should not be used for other than its intended purpose.

Management does not rely upon the following information in making
investment and operating decisions. The Company, along with its partners, bases
such decisions upon a wide range of factors, including estimates of probable as
well as proved reserves, and varying price and cost assumptions considered more
representative of a range of possible economic conditions that may occur in the
future.
