ITEM 1.   BUSINESS


General

     Seitel,  Inc.  (the  "Company")  is a leading  provider of seismic data and
corollary  geophysical  technology used in petroleum exploration and production.
The Company sells its proprietary  information-technology to petroleum companies
either for cash or  selectively  in  exchange  for working  equity-interests  in
exploration,  development  and  ownership of natural gas and crude oil reserves.
See Note O to the  Company's  Consolidated  Financial  Statements  for financial
information relating to industry segments.

Seismic Operations

     Since  its  inception  in  1982,  the  Company  has  been  engaged  in  the
development  of a  proprietary  library  of  seismic  data,  created by both the
Company and others.  The Company's seismic data library is owned and marketed by
Seitel Data,  Ltd., a Texas limited  partnership  of which  wholly-owned  Seitel
subsidiaries  constitute all of the limited and general  partners.  Seitel Data,
Ltd. markets the data library, which consists of both two-dimensional ("2D") and
three-dimensional   ("3D")  data,  to  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.

     In 1997,  approximately  400  different  petroleum  companies  entered into
seismic data license  agreements  with the  Company.  At December 31, 1997,  the
Company owned  approximately  885,000 linear miles of 2D and approximately 9,000
square miles of 3D seismic data which it maintained in its library, which, based
solely on management's knowledge and beliefs regarding the industry, constitutes
the second largest seismic data base marketed  publicly in North America.  While
the majority of the seismic  surveys  cover  onshore and offshore the U.S.  Gulf
Coast,  the  Company's  data bases  extend to  virtually  every  major  domestic
exploration and development region and 32 foreign countries.

     The Company's  marketing team of 15 seismic sales specialists  markets data
from its library and from newly created 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   petroleum   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 22 member staff of geotechnical professionals who have in
excess  of  400  years  of  collective  geophysical  experience.  Together,  the
marketing  team and  geotechnical  professionals  help  clients  evaluate  their
respective  seismic  requirements,  design data creation programs to meet market
demand,  and supervise  the  reprocessing  of data in the  Company's  library to
enhance future resales.

     Three-dimensional  seismic data provide 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  present 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  subsurface  hydrocarbons.  The proper  use of 3D surveys  can
significantly  increase  drilling  success  rates and reduce the  occurrence  of
costly dry holes  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 remain  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.
<PAGE>

     The Company conducts data creation activities in two ways;  multi-client or
"group shoot" programs and proprietary acquisition programs for its wholly-owned
petroleum  exploration  and  production  subsidiary,   DDD  Energy,  Inc.  ("DDD
Energy"), and DDD Energy's partners. The Company contracts with selected seismic
acquisition crew companies,  including its former wholly-owned subsidiary, Eagle
Geophysical,  Inc., to conduct both onshore and offshore seismic  surveys.  In a
group  shoot  program,  several  petroleum  companies  share in the expense of a
survey and thereby  materially  reduce their respective cost of the survey. In a
group-shoot  survey,  the  Company  retains  ownership  of the data  created and
markets  licenses  to use the  data  both to the  group-shoot  participants  and
subsequently  to  others  who make  selections  after  the data are added to the
Company's library.  (Seismic data cannot be transferred by a licensee to another
party; each individual user must purchase a respective license.)

     The DDD Energy 3D surveys are intended to assist participation in petroleum
exploration  and  development,  whereby DDD Energy's  ownership  interest in any
resultant  production  will be  accounted  for as "oil  and  gas"  revenues  and
reserves.  To date,  over 1,500 square miles of advanced 3D seismic surveys have
been  conducted for DDD Energy and its  exploration  partners.  In excess of 500
square  miles of 3D surveys are already  scheduled  to be  conducted in 1998 and
1999 by DDD Energy and its partners.

     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. 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.

     The Company  wholly-owned a seismic data  acquisition  crew company,  Eagle
Geophysical,  Inc.  ("Eagle"),  until  August  11,  1997,  at which  time it was
spun-off  as an  independent  company.  The  Company  now has a 17.9%  ownership
interest in Eagle.

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 petroleum exploration,
development   and  ownership  of   hydrocarbon   reserves   through   partnering
relationships  with oil and gas  companies,  whereby the Company  exchanges  its
proprietary seismic technology for working interests.  The Company's strategy is
to combine its 3D and 2D seismic resources and related geophysical  technologies
with the land  position  and  geology,  engineering  and  drilling  expertise of
selected  petroleum  producers 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/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,  DDD Energy has entered  into and  maintained
cost and  revenue-sharing  relationships with more than 100 petroleum  companies
and, in doing so, has received the benefit of these petroleum  companies'  land,
geological,  engineering  and drilling  staffs.  The Company has conducted  over
1,500  square  miles of advanced 3D surveys,  with more than 500 square miles of
new surveys currently scheduled to be conducted for DDD Energy and its partners,
located  primarily  onshore  Texas  and  Louisiana,  and also  onshore  Alabama,
Mississippi and Arkansas. DDD Energy's working interest in these projects ranges
from approximately 10% to 90%, with an average working interest of approximately
31%.  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.

     Since inception,  DDD Energy has participated in the drilling of 240 wells,
165 of which are commercially productive for a 69% success rate.

Customers

     During  1997,   the   Company's   seismic  data   customers   consisted  of
approximately 400 oil and gas companies.  No one customer  accounted for as much
as 10% of the  Company's  revenues  during the years  1997,  1996 or 1995.  As a
result,  the Company does not believe that the loss of any customer would have a
material adverse impact on its seismic  business.  The Company believes the size
of its customer base is due to its seismic  technology and  capabilities and the
increasing size of its data-library base.


<PAGE>


Competition

     The  creation  and resale of seismic  data are  highly  competitive  in the
United  States.  There is a number of  independent  oil-service  companies  that
create and market  seismic  data,  and  numerous  oil and gas  companies  create
seismic data and maintain  their own seismic data banks.  Some of the  Company's
competitors have longer operating  histories,  greater  financial  resources and
larger  sales  volumes  than the  Company.  However,  the number of  independent
seismic  companies  has  decreased  significantly  during the last decade due to
difficult industry conditions. In 1985, there were approximately 150 independent
seismic companies operating in the United States, of which approximately 15 were
significant competitors.  In 1997, there were approximately 100 companies,  with
approximately 10 significant competitors.  With the U.S. "oil patch" collapse in
1985, many of the independent seismic companies went out of business; during the
1990's, this industry has witnessed a major consolidation. At the same time, oil
and gas  companies  have  reduced  their  internal  geophysical  staffs and have
out-sourced  more for services such as seismic data. 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  geotechnical  staff.  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 corollary geophysical expertise combined
with  the  geological  and  engineering  experience  and land  positions  of the
Company's petroleum 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 petroleum  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 petroleum 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 operation,  bringing
a  small  number  of  high-production  wells  on line  in a  given  quarter  can
materially  impact the results of such quarter  since many of the wells in which
the  Company  participates  flow at high  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 such wells are  brought on line in a quarter,  the results
for such 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  periodically to go off line  temporarily 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  P  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, 1997, the Company and its  subsidiaries had 94 full-time
employees  and three  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, 63 are related
to the seismic operations and 16 are related to the oil and gas operations.  The
balance provide  accounting and administrative  support for all operations.  The
Company believes it has a favorable relationship with its employees. The Company
has employment contracts with five of its senior corporate executives.

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, 1997, see Note Q 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 Q to the  Company's  Consolidated  Financial
statements represent 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, 1997.  Gross oil and gas wells  include 10
with  multiple  completions.  All of the wells  are  operated  by the  Company's
petroleum company partners.

Dividend Policy

     The Company did not pay cash dividends  during 1996 or 1997, 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.

Results of Operations

     Total revenue was  $127,556,000,  $106,002,000 and 74,439,000 in 1997, 1996
and 1995, respectively,  representing increases of 20% from 1996 to 1997 and 42%
from 1995 to 1996.  Revenue  primarily  consists of revenue  generated  from the
marketing of seismic data, oil and gas production and  proprietary  seismic data
acquisition (until August 11, 1997).

     Revenue from the marketing of seismic data was $85,560,000, $67,138,000 and
$55,749,000  during 1997,  1996 and 1995,  respectively.  The increases  between
years are primarily  attributable  to an increase in demand for  high-resolution
seismic data,  which is being used  increasingly  in oil and gas exploration and
development  efforts.  The  Company  believes  the demand for its  seismic  data
remains strong due to several  factors:  large  integrated oil and gas companies
are  increasingly  utilizing  3D  seismic to  evaluate  the  probability  of the
existence and location of hydrocarbons; they have reduced their internal seismic
data  crew  staffs  and are  using  outside  sources  to  provide  more of these
services;  the  majority of the  Company's  seismic  data is located in the Gulf
Coast region,  which  continues to be of particular  interest to the oil and gas
industry;  and the high quality of the  Company's  seismic  data.  Additionally,
management believes that the Company's 2D data library will continue to generate
significant revenue because 2D data is less expensive than 3D and 2D data is the
most cost-efficient means to preliminarily  identify exploration and development
leads, which are then best evaluated with 3D data.

     Oil and gas revenue was  $25,680,000,  $18,255,000  and  $4,806,000  during
1997,  1996 and 1995,  respectively.  The  increases  in oil and gas revenue are
primarily due to higher  production  resulting  from more wells being on line in
1996 and 1997.  The first year of oil and gas  operations  for the  Company  was
1993.  Since then,  the Company  has  steadily  increased  its  exploration  and
development  efforts  resulting  in 68 wells  producing  as of December 31, 1995
increasing  to 92 at  December  31, 1996 and to 122 at December  31,  1997.  Net
volume and price  information  for the Company's oil and gas  production for the
years ended  December 31, 1997,  1996 and 1995 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):

     Revenue from the  acquisition  of  proprietary  seismic data and leasing of
seismic  equipment  ("geophysical  services")  performed by the Company's former
seismic  acquisition crew subsidiary,  Eagle Geophysical,  Inc.  ("Eagle"),  was
$16,316,000,  $20,609,000 and $13,884,000 for 1997, 1996 and 1995, respectively.
The  decrease  from 1996 to 1997 is a result of the  spin-off of Eagle on August
11, 1997.  Consequently,  the geophysical  services  revenue for 1997 represents
approximately  seven and one-half months,  whereas 1996 represented a full year.
The increase  between 1995 and 1996 is primarily  attributable to an increase in
the channel  capacities of both crews.  Additionally,  revenue from  geophysical
services  recognized  by the  Company  varies  based on  whether  projects  were
performed  for other  subsidiaries  of the Company,  in which case no revenue is
recognized, or were performed for third parties.

     Depreciation,  depletion and  amortization  consist  primarily of data bank
amortization  and depletion for oil and gas properties.  Data bank  amortization
amounted  to  $35,163,000,  $30,477,000  and  $23,852,000  for the  years  ended
December 31, 1997, 1996 and 1995, respectively.  As a percentage of revenue from
licensing  seismic data, data bank  amortization  was 42%, 47% and 45% for 1997,
1996 and 1995,  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 stream and, in 1997, an
increase  in  revenue  from  purchased  seismic  data  which is  amortized  on a
straight-line  basis.  The costs of the Company's  proprietary  seismic data are
amortized  for each  project in the  proportion  that its  revenue  for a period
relates to management's  estimate of its ultimate revenues.  Revenue is expected
to be more evenly  received  over the lives of existing  seismic data  libraries
purchased by the Company.  Accordingly,  the Company amortizes the cash invested
in purchases of existing seismic data libraries evenly over ten years.

     Since inception, management has established guidelines regarding its annual
charge for amortization. Under these guidelines, 90% of the cost incurred in the
creation of proprietary seismic data is amortized within five years of inception
for 2D seismic  data and within seven years of  inception  for 3D data,  and the
final 10% is amortized on a straight-line  basis over fifteen years. Under these
guidelines,  costs of existing  seismic data libraries  purchased by the Company
are fully amortized within ten years from date of purchase. On a periodic basis,
the carrying  value of seismic data is compared to its estimated  future revenue
and, if appropriate, is reduced to its estimated net realizable value.

     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.  Pricing of  seismic  data is  significant  when it  indicates  a
revision to estimated  future  revenue.  During periods of expected  declines in
activity,  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,  that  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.

     Depletion of oil and gas  properties,  excluding the  impairment  discussed
below, was  $12,666,000,  $7,212,000 and $1,625,000 for the years ended December
31, 1997, 1996 and 1995, respectively,  which amounted to $1.34, $1.02 and $.70,
respectively,  per mcfe of gas  produced  during such  periods.  The increase in
rates  reflects  the  amount  of  exploration  and  development  costs  incurred
increasing at a higher rate than the proven reserve base.

     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 is primarily due to lower commodity prices as compared to
the December 31, 1996 and 1997 prices.

     Cost  of  sales  consists  of  expenses  associated  with  the  oil and gas
production and geophysical  services (until August 11, 1997), as well as seismic
resale support  services.  The increases in cost of sales related to oil and gas
production is directly  attributable  to the increase in revenue from this area.
Oil and gas  production  costs  amounted  to  $.55,  $.44,  $.66 per mcfe of gas
produced  during 1997,  1996 and 1995,  respectively.  The variation in rates is
primarily attributable to the number of oil wells the Company has in relation to
its total wells as oil wells typically have higher  associated  production costs
than gas wells. Additionally, in 1997, ad valorem taxes increased as a result of
the increase in the value of  reserves.  The increase in cost of sales from 1995
to 1996 related to the acquisition of seismic data for non-affiliated parties is
due to an increase in revenue from this area.  The decrease from 1996 to 1997 is
due to the 1997  cost of sales  reflecting  only  seven and  one-half  months of
activity as a result of the spin-off of Eagle,  whereas 1996  represented a full
year.  Gross  profit  margin  related to the  acquisition  of  seismic  data for
non-affiliated  parties  (revenue  less cost of sales) was 19%,  21% and 22% for
1997, 1996 and 1995, respectively.

     The Company's selling,  general and administrative  expenses increased from
$15,393,000 in 1995 and $19,165,000 in 1996 to $23,043,000 in 1997. The increase
for each year 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 21% in
1995 and  decreased to 18% in 1996 and 1997.  The  decrease is primarily  due to
ongoing cost reduction programs.

     The Company's  interest expense was $3,407,000 in 1995,  $4,063,000 in 1996
and $4,610,000 in 1997.  The increase in interest  expense from 1995 to 1996 was
primarily due to interest expense incurred on the Company's Senior Notes;  $52.5
million was outstanding  during all of 1996 and an additional  $22.5 million was
outstanding  for  approximately  nine months of 1996.  The increase from 1996 to
1997 was  primarily  due to  interest  incurred  on  borrowings  made  under the
Company's  revolving  line of credit  during  1997 along with the full amount of
Senior Notes being outstanding for all of 1997.

     Interest income was $329,000 in 1995,  $1,163,000 in 1996 and $1,055,000 in
1997.  The increase  from 1995 to 1996 was  primarily  attributable  to interest
earned on the  investment of increased cash balances as a result of the proceeds
from the Senior  Notes.  The decrease from 1996 to 1997 was primarily due to the
fluctuation 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. As a result of the offering, the Company now owns 1,520,000
shares of Eagle common stock or 17.9% of the  outstanding  shares of Eagle.  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.  Additionally,  the Company recorded a pre-tax gain, net of
costs,  of  $10,750,000,  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.  The Company's equity in earnings of Eagle was $146,000 for the period
from August 11, 1997 to December 31, 1997.

     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.

     During a portion of 1996,  the  Company  had a 50%  ownership  interest  in
Energy Research  International  ("ERI"), a holding company which wholly owns two
marine seismic companies,  Horizon  Exploration Limited and Horizon Seismic Inc.
The ownership  interest in ERI was reduced to 19% in late 1996. During 1996, the
Company recognized a net loss from its interest in ERI of $186,000. In May 1997,
the Company contributed its 19% ownership interest in ERI to Eagle.

     On March 22, 1996, the Company's Board of Directors  unanimously  adopted a
plan of disposal to  discontinue  the Company's gas  marketing  operations,  the
final disposal and sale of which was completed during the third quarter of 1996.
Accordingly,  the Company's  consolidated  financial  statements present the gas
marketing operations as discontinued  operations for all periods presented.  The
Company  decided  to  refocus  and  concentrate  on its  higher  margin  seismic
technology   operations  and  related   petroleum   exploration  and  production
operations in order to maximize  profitability and growth opportunities.  A loss
from  discontinued  operations  of  $1,196,000,  which is net of an  income  tax
benefit of  $703,000,  was recorded as of December  31,  1995.  During 1996,  an
additional loss from  discontinued  operations was recorded  totaling  $988,000,
which is net of an income tax benefit of $580,000.  The additional loss resulted
from changes in market prices to purchase gas supply.  Such loss represented the
final charge  related to the  discontinued  operations.  The loss on disposal of
discontinued operations recorded as of December 31, 1995, was $252,000, which is
net of an income tax benefit of $148,000,  and included  costs such as severance
benefits  and  personnel  costs to continue to honor the  Company's  obligations
until the gas marketing contracts were transferred or terminated.

Liquidity and Capital Resources

     As a result of its sale of 1,880,000 shares of Eagle common stock on August
11,  1997,  the Company  received net  proceeds of  $29,723,000  which were used
primarily to fund  additions to the  Company's  seismic data library and oil and
gas  properties.  As of December  31, 1997,  the market  value of the  Company's
remaining equity interest in Eagle was $19,760,000, based on 1,520,000 shares at
the  December  31, 1997  closing  price of $13.00 per share as quoted by NASDAQ.
These shares are subject to certain trading restrictions.

     Because  Eagle is no  longer  consolidated  in the  Company's  consolidated
financial  statements,  the amount of the Company's term loans and capital lease
obligations was reduced to $385,000 and $71,000,  respectively,  as of March 27,
1998. The Company also received repayment of debts owed directly to it by Eagle,
plus advances,  amounting to  $2,094,000.  At December 31, 1997 the Company owed
$12,500,000 to this affiliate for seismic survey services.

     From July  1995 to April  1997,  the  Company  and two of its  wholly-owned
subsidiaries  obtained four separate three-year term loans totaling  $1,077,000.
Two of the loans bear  interest  at the rate of  8.413%,  and two at the rate of
7.9%. The proceeds were used for the purchase of certain  property and equipment
which  secures  the  debt.   Monthly   principal  and  interest  payments  total
approximately  $34,000.  The balance outstanding on the loans at March 27, 1998,
was $385,000.

     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 $8.333 million beginning December 30, 1999.
The  Series B and  Series C Notes  mature on  December  30,  2002,  and  require
combined annual principal  payments of $10 million beginning  December 30, 1998.
Interest  on all  series of the notes is  payable  semi-annually  on June 30 and
December 30.

     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, par
value $0.01 per share,  and (iii) common stock, par value $.01 per share, 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.

     On  March  16,  1998,  the  Company  increased  its  $50,000,000  unsecured
revolving line of credit facility to $75,000,000. 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 3/4%, the bank's  prevailing prime rate, or the sum of
the Federal Funds effective rate for such day plus 1/2%. The facility matures on
March 16, 2001. As of March 27, 1998,  the balance  outstanding on the revolving
line of credit amounted to $18,000,000 bearing an interest rate of 6.44%.

     In June 1996, a  wholly-owned  subsidiary  of the Company sold a volumetric
production payment for $19 million to certain limited  partnerships.  During the
third quarter of 1997, the subsidiary  extinguished the remaining portion of its
volumetric production payment at a cost of $13,352,000.

     During 1997 and 1996, the Company  received  $17,361,000  and  $11,182,000,
respectively,  from the exercise of common stock  purchase  warrants and options
and the Company's  401(k) stock  purchases.  In  connection  with the option and
warrant  exercises in 1997 and 1996,  the Company also received  $5,657,000  and
$3,204,000,  respectively,  in tax savings.  From January 1, 1998, through March
27,  1998,  the  Company  received  $59,000  from  the  Company's  401(k)  stock
purchases.

     In February 1996,  the Company called for the March 31, 1996  redemption of
its 9% convertible subordinated debentures,  thereby eliminating future interest
and sinking fund payments.  All remaining  outstanding  debentures  converted to
common stock.

     During December 1997, the Company  repurchased 175,000 shares of its common
stock in the open market at a cost of $2,973,000, pursuant to a stock repurchase
program authorized by the Board of Directors on December 12, 1997. The Board has
authorized  expenditures  of up to $25  million  towards the  repurchase  of its
common stock.

     During 1997,  gross seismic data bank additions and capitalized oil and gas
exploration  and  development  costs  amounted to $89,073,000  and  $50,597,000,
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 Eagle stock  discussed  above,  proceeds
received  from the  exercise  of common  stock  purchase  warrants  and  options
combined  with tax savings  received on the exercise of the warrants and options
and borrowings under the Company's revolving line of credit.

     Currently,  the Company anticipates capital  expenditures for 1998 to total
approximately $167 million. Such expenditures include approximately $130 million
for the creation of proprietary  seismic data, and approximately $37 million for
oil and gas  exploration  and  development  efforts.  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 and  project  financing  where  applicable,
should  be  sufficient  to  fund  the  1998  capital  expenditures,  along  with
expenditures   for   operating   and   general  and   administrative   expenses.
Additionally,  the Company could arrange for additional debt or equity financing
during 1998;  however,  there can be no assurance that the Company would be able
to accomplish any such debt or equity financing on satisfactory terms.

Recent Accounting Pronouncements

     In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting  Comprehensive  Income." The statement establishes standards
for reporting and display of  comprehensive  income and its components in a full
set  of  general-purpose  financial  statements.   The  statement  requires  (a)
classification  of items of other  comprehensive  income  by their  nature  in a
financial   statement   (b)  display  of  the   accumulated   balance  of  other
comprehensive  income  separate from retained  earnings and  additional  paid-in
capital in the equity section of a statement of financial position. SFAS No. 130
is  effective  for  fiscal  years   beginning   after   December  15,  1997  and
reclassification  of  financial  statements  for earlier  periods  provided  for
comparative purposes is required.

     In June 1997, the FASB issued SFAS No. 131,  "Disclosures about Segments of
an Enterprise and Related  Information." Under the new standard,  companies will
be  required  to  report  certain   information  about  operating   segments  in
consolidated  statements.  Operating  segments will be  determined  based on the
method by which management organizes its business for making operating decisions
and assessing  performance.  The standard also  requires that  companies  report
certain  information about their products and services,  the geographic areas in
which they  operate,  and their major  customers.  SFAS No. 131 is effective for
financial statements for periods beginning after December 15, 1997.

Year 2000

     The Company utilizes  software and  technologies  throughout its operations
that will be affected  by the date change in the year 2000 ("Year 2000  Issue").
An  assessment  of the systems  that will be affected by the Year 2000 Issue has
been made. The Company does not believe the costs related to the Year 2000 Issue
will  materially  impact its  results of  operations.  However,  there can be no
guarantee that the systems of other  companies,  on which the Company's  systems
rely,  will be timely  converted or that a failure to convert by another company
or a conversion that is incompatible with the Company's systems would not have a
material adverse effect on the Company.

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, 1997.

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.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     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. These financial  instruments
are  designated  as hedges and accounted for on the accrual basis with gains and
losses being recognized based on the type of contract and exposure being hedged.
Realized  gains  or  losses  on  natural  gas  swaps  designated  as  hedges  of
anticipated  production  are  treated as  deferred  credits  or charges  and are
included in other  liabilities or other assets on the balance  sheet.  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,  are deferred and recognized in income when the associated  hedged
commodities  are  produced.  The Company did not  materially  hedge  natural gas
prices in 1997.  The  Company  continually  reviews  and may  alter  its  hedged
positions.

                    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, 1997 and 1996, and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended  December 31, 1997.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Seitel,  Inc. and subsidiaries
as of December 31, 1997 and 1996, and the results of their  operations and their
cash flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

SEITEL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1997

NOTE A--SIGNIFICANT ACCOUNTING POLICIES

     NATURE OF OPERATIONS: Seitel, Inc. (the "Company") is a leading provider of
seismic data and corollary  geophysical  services to the petroleum  industry and
directly  participates in exploration,  development and ownership of natural gas
and crude oil reserves.  The majority of the Company's  seismic  surveys  covers
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 onshore Texas and Louisiana, and also onshore Alabama, Mississippi and
Arkansas.

     USE  OF  ESTIMATES:   The  preparation  of  these  consolidated   financial
statements  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.  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 Q, "Supplemental Oil and Gas
Information"  for  additional  information  regarding  the process of estimating
proved oil and gas reserve quantities.

     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. Seismic data costs are amortized
for each  project in the  proportion  that its revenue  for a period  relates to
management's estimate of its ultimate revenues. Since inception,  management has
established guidelines regarding its annual charge for amortization. Under these
guidelines, 90% of the cost incurred in the creation of proprietary seismic data
is amortized within five years of inception for two-dimensional seismic data and
within seven years of inception for three-dimensional data, and the final 10% is
amortized on a straight-line basis over fifteen years. Costs of existing seismic
data  libraries  purchased by the Company are fully  amortized  within ten years
from date of  purchase.  Using these  guidelines,  the Company  would expect the
percentage  of net data bank as of December  31, 1997 to be amortized to be 23%,
20%, 14%, 13%, 10%, and 20% for the years ending December 31, 1998,  1999, 2000,
2001, 2002 and all periods  thereafter,  respectively.  On a periodic basis, the
carrying value of seismic data is compared to its estimated  future revenue and,
if appropriate, is reduced to its estimated net realizable value.

                                      =============      =============

     PROPERTY  AND  EQUIPMENT:   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 directly related
overhead  costs,  and interest costs related to its  unevaluated  properties and
certain  properties under  development  which are not currently being amortized.
For the three years ended December 31, 1997, exploration and development related
overhead costs of $1,431,000,  $1,146,000 and $861,000,  respectively, have been
capitalized  to oil and gas  properties.  For the three years ended December 31,
1997, interest costs of $2,105,000,  $1,525,000 and $835,000, respectively, have
been capitalized to oil and gas properties.

     Provisions  for  depreciation,  depletion and  amortization  are calculated
using  the  units-of-production   method.  Estimated  future  site  restoration,
dismantlement  and  abandonment  costs,  net of salvage  values,  are taken into
consideration. Such costs are not currently expected to be material. Capitalized
costs associated with the acquisition and evaluation of unproved  properties and
certain  properties under development are not currently  depleted.  Depletion of
the costs  associated with these properties will commence when the properties or
projects are evaluated.

     Capitalized  costs are  limited  to the  present  value,  discounted  at 10
percent, of future net revenues from estimated proved reserves, based on current
economic  and  operating  conditions,  plus the  lower of cost or fair  value of
unevaluated  properties,  adjusted for the effects of related  income taxes.  If
capitalized  costs  exceed  this limit,  the excess is charged to  depreciation,
depletion and amortization.  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 the fourth quarter of 1997.

     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.

     INCOME TAXES: The Company and all of its  subsidiaries  file a consolidated
federal income tax return. The Company does not provide deferred taxes (benefit)
on the undistributed earnings (loss) of its foreign subsidiaries, which amounted
to $207,000,  $445,000 and $(3,000) for the years ended December 31, 1997,  1996
and  1995,  respectively,  as  such  earnings  are  intended  to be  permanently
reinvested in foreign operations.

     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.

     COST OF SALES:  Cost of sales  consists  of  expenses  associated  with the
acquisition of seismic data for non-affiliated  parties, oil and gas production,
and data  resale  support  services.  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.

                                       F-9

     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 year-end exchange rates and revenue and expenses are translated at
the  current  exchange  rates  as of the  dates on  which  they are  recognized.
Translation  adjustments are included as a separate  component of  shareholders'
equity. Any gains or losses on transactions or monetary assets or liabilities in
currencies other than the functional  currency are included in net income in the
current period.

     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. These
financial  instruments are designated as hedges and accounted for on the accrual
basis with gains and losses being  recognized  based on the type of contract and
exposure being hedged.  Realized gains or losses on natural gas swaps designated
as hedges of anticipated  production are treated as deferred  credits or charges
and are included in other  liabilities or other assets on the balance sheet. 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,  are deferred and recognized in income when the associated  hedged
commodities  are produced.  In order for natural gas swaps to qualify as a hedge
of an  anticipated  transaction,  the  derivative  contract  must  identify  the
expected  date of the  transaction,  the  commodity  involved,  and the expected
quantity to be purchased or sold.  In the event that a hedged  transaction  does
not occur, future gains and losses,  including  termination gains or losses, are
included in the income statement when incurred. The estimated fair value of open
commodity  price hedges as of December 31, 1997 was a gain of $183,000 and as of
December 31, 1996 was a loss of $408,000.

     In the  statement  of cash flows,  cash  receipts  or  payments  related to
financial  instruments  are classified  consistent  with the cash flows from the
transaction being hedged.

     EARNINGS  PER  SHARE:  The  Company  has  adopted  Statement  of  Financial
Accounting  Standards  ("SFAS") No. 128,  "Earnings Per Share,"  which  requires
restatement of all comparative  per share amounts.  Under the provisions of SFAS
No. 128, the  presentation of primary  earnings per share has been replaced with
basic  earnings per share,  and fully diluted  earnings per share  presentations
have been  replaced  with diluted  earnings per share for  potentially  dilutive
securities such as outstanding  options,  convertible  debt and preferred stock.
All prior period earnings per share data have been restated.

     Basic earnings per share are computed based on the weighted  average shares
of common stock outstanding.  Earnings per share computations to reconcile basic
and diluted income from continuing  operations for the years 1997, 1996 and 1995
consist of the following (in thousands except per share amounts):

     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 G, "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 1997, 1996 and 1995.

     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, 1997 and 1996,  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  the carrying  value of this debt as of December 31, 1997 and 1996.
As of December 31,  1997,  the market value of the  Company's  remaining  equity
interest  in Eagle  Geophysical,  Inc.  ("Eagle")  was $19.8  million,  based on
1,520,000  shares at the December closing price of $13.00 per share as quoted by
NASDAQ.

     IMPAIRMENT OF LONG-LIVED  ASSETS:  Effective  January 1, 1996,  the Company
adopted  the  requirements  of SFAS  No.  121,  "Accounting  for  Impairment  of
Long-Lived  Assets and for Long-Lived  Assets to be Disposed Of." This statement
requires that  long-lived  assets be reviewed for impairment  whenever events or
changes in circumstances indicate that the carrying value of an asset may not be
realizable.  There were no impairments recorded under SFAS No. 121 in 1997, 1996
or 1995.

     RECENT ACCOUNTING  PRONOUNCEMENTS:  In June 1997, the Financial  Accounting
Standards Board ("FASB") issued SFAS No. 130, "Reporting  Comprehensive Income."
The statement  establishes  standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
The statement requires (a) classification of items of other comprehensive income
by their  nature in a financial  statement  and (b)  display of the  accumulated
balance of other  comprehensive  income  separate  from  retained  earnings  and
additional  paid-in  capital in the equity  section of a statement  of financial
position.  SFAS No. 130 is effective for fiscal years  beginning  after December
15, 1997 and  reclassification  of  financial  statements  for  earlier  periods
provided for comparative purposes is required.

     In June 1997, the FASB issued SFAS No. 131,  "Disclosures about Segments of
an Enterprise and Related  Information." Under the new standard,  companies will
be  required  to  report  certain   information  about  operating   segments  in
consolidated  statements.  Operating  segments will be  determined  based on the
method by which management organizes its business for making operating decisions
and assessing  performance.  The standard also  requires that  companies  report
certain  information about their products and services,  the geographic areas in
which they  operate,  and their major  customers.  SFAS No. 131 is effective for
financial statements for periods beginning after December 15, 1997.

     SENIOR  NOTES:  On  December  28,  1995,  the  Company  completed a private
placement of three series of unsecured  Senior Notes totaling  $75,000,000.  The
Company  contemporaneously  issued its Series A Notes and Series B Notes,  which
total  $52,500,000  and bear  interest  at the fixed rate of 7.17%.  On April 9,
1996, the Company issued its Series C Notes,  which total  $22,500,000  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 $8,333,000 beginning December 30,
1999.  The Series B and Series C Notes mature on December 30, 2002,  and require
combined annual principal  payments of $10,000,000  beginning December 30, 1998.
Interest on the Senior  Notes is payable  semi-annually  on June 30 and December
30.

     LINE OF CREDIT:  The  Company's  $50 million  unsecured  revolving  line of
credit facility was increased to $75 million on March 16, 1998, and the maturity
date was  extended  from July 22, 1999 to 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 3/4%, the bank's  prevailing  prime rate, or
the sum of the Federal Funds  effective rate for such day plus 1/2%. The average
interest  rate  applicable to amounts  outstanding  under this facility was 7.1%
during 1997.

     TERM LOANS:  From 1995 to 1997,  the  Company  and two of its  wholly-owned
subsidiaries  obtained four separate three-year term loans totaling  $1,077,000.
Two of the loans bear  interest  at the rate of  8.413%,  and two at the rate of
7.9%. The proceeds were used for the purchase of certain  property and equipment
which  secures  the  debt.   Monthly   principal  and  interest  payments  total
approximately $34,000.

     Certain of the borrowings  described  above contain  requirements as to the
maintenance  of minimum net worth and  limitations  on liens,  total debt,  debt
issuance and disposition of assets.

     Aggregate  maturities of the Company's debt over the next five years are as
follows:  $10,306,000  in  1998;  $18,460,000  in  1999;  $18,378,000  in  2000;

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, 1997 and 1996, $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.

     On  January  27,  1995,  the  Company's  Board  of  Directors   approved  a
shareholder   value  incentive  bonus  under  which  a  cash  bonus  aggregating
$4,000,000  would be paid to all  salaried  employees if the market price of the
Company's stock reaches $30 per share on or before April 30, 1998, and maintains
that price for at least 90 consecutive  days.  This bonus would be shared by all
salaried  employees on a basis  proportionate to their  respective  compensation
ranking  in the  Company,  and it  would  vest  and be  paid  out in  escalating
quarterly installments over a three-year period, subject to continued employment
with the Company. As of March 26, 1998, the market price of the Company's common
stock was $15.625 per share.

     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 profitability.  Part III of the Company's Form 10-K contains a more
complete discussion of these contractual obligations.

     The Company  applies APB  Opinion  No. 25 and  related  interpretations  in
accounting for its stock-based  compensation plans. APB No. Opinion 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):

     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
1997,  1996 and 1995,  respectively:  (1) risk-free  interest rates ranging from
5.79% to 6.79%,  5.9% to 7.03% and 5.54% to 7.02%;  (2) dividend yield of 0%, 0%
and 0%; (3) stock price  volatility  ranging  from  37.23% to 45.77%,  46.49% to
62.62% and 47.18% to 65.06%;  and (4) expected option lives ranging from 1.67 to
10 years, 5 to 10 years and 2.8 to 10 years. The weighted-average  fair value of
options  granted  during  1997,  1996 and 1995 was  $9.98,  $11.20 and $9.66 per
option,  respectively,  for options  granted at fair market value and $10.15 and
$9.43 per option for options  granted  above fair market value in 1997 and 1995,
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.

     On July 25, 1996, the Company's Board of Directors adopted the 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  directors  fees in a deferred cash account or as deferred
shares.  As of December 31, 1997,  60,000 shares have been reserved for issuance
under this plan and directors have  accumulated  1,643 deferred  shares in their
accounts which will begin to be distributed in January 1998 in five equal annual
installments.

NOTE H--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.  During December
1997,  the  Company  repurchased  175,000  shares of  common  stock at a cost of
$2,973,000.

     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, par
value $0.01 per share,  and (iii) common stock, par value $.01 per share, 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.

     On July 21, 1992, the Company granted ten-year loans at an interest rate of
4% to most of its employees  for purchases of the Company's  common stock at the
then market price of $2.69 per share. The Company recorded related  compensation
expense due to the below market interest rate on these loans of $43,000, $48,000
and $56,000 for the years ended December 31, 1997, 1996 and 1995,  respectively.
Payments of 5% of the original  principal  balance plus accrued interest are due
annually August 1, with a balloon payment of the remaining principal and accrued
interest due August 1, 2002.  During 1997,  1996 and 1995, the Company  received
$96,000,  $190,000 and  $156,000  respectively,  as principal  payments on these
notes.  The stock  certificates  are held by the  Company  as  collateral  until
payment is received.

NOTE I--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, 1997, no preferred stock had been issued.

NOTE J--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.

     On August 11, 1997,  the Company's  wholly-owned  seismic data  acquisition
crew  subsidiary,  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.  As a result of the  Offering,  the  Company now owns
1,520,000  shares of Eagle common stock, or 17.9% of the  outstanding  shares of
Eagle. The Company  received net proceeds of $29,723,000 from its  participation
in the Offering, resulting in a pre-tax gain, net of costs, on the sale of Eagle
common stock of $18,449,000.  Additionally, the Company recorded a pre-tax gain,
net  of  costs,  of  $10,750,000  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.

NOTE K--RELATED PARTY TRANSACTIONS

     The Company  owed Eagle and its  subsidiaries  $12,500,000  at December 31,
1997 for  seismic  data  acquisition  services  provided  to the Company and its
subsidiaries  subsequent to the Offering date. The Company  incurred  charges of
$22,200,000 for these services from the period August 11, 1997 through  December
31,  1997.  Costs  incurred  from  these  services  were  based on  agreed  upon
contractual amounts and terms similar to contracts with third party contractors.

     The Company and Eagle  entered  into a Master  Separation  Agreement  ("the
Agreement") for the purpose of defining their continuing  relationship after the
Offering.  The  Agreement  provides  for the  Company  and Eagle to enter into a
Sublease, a Registration Rights Agreement and a Tax Indemnity  Agreement.  Under
the Agreement, the Company and Eagle have indemnified each other with respect to
liabilities  arising  in  connection  with the  operations  of their  respective
businesses prior to and after the date of consummation of the Offering including
liabilities under the Securities Act with respect to the Offering.  The Sublease
between the Company and Eagle  provides for the Company to sublease a portion of
its  principal  corporate  offices to Eagle for a term of three years  beginning
August  1997 at an annual  rent of  approximately  $83,000.  The  Sublease  also
provides for Eagle to utilize  certain  shared office  equipment,  such as phone
systems and central computer systems, for an additional charge.  Pursuant to the
Registration  Rights Agreement,  Eagle has agreed to register the offer and sale
by the Company on a delayed and continuous basis from time to time of the shares
of common stock owned by the Company after the Offering at the expense of Eagle.
The Company and Eagle have  entered  into a Tax  Indemnity  Agreement  to define
their  respective  rights and obligations  relating to federal,  state and other
taxes for periods  before and after the Offering.  Pursuant to the Tax Indemnity
Agreement, Eagle is required to pay the Company (to the extent not already paid)
its share of  federal  income  taxes  prior to the date of  consummation  of the
Offering, and is responsible for federal income taxes from its operations on and
after the date of the Offering.  Any  subsequent  refunds,  additional  taxes or
penalties  or other  adjustments  relating to Eagle's  federal  income taxes for
periods  prior  to the date of  consummation  of the  Offering  shall be for the
benefit of or be borne by the Company.  Similar  provisions  apply under the Tax
Indemnity Agreement to other taxes, such as state and local taxes.

     The Company owed Helm  Resources,  Inc. and its  subsidiaries  ("Helm"),  a
company  that has three  executive  officers  who are  directors of the Company,
$76,000 and $23,000 as of December 31, 1997 and 1996, respectively, 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  $76,000,
$80,000 and $78,000 for these general and  administrative  expenses during 1997,
1996 and 1995, 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  invest  in  the  exploration  and
development of oil and gas properties on a working interest basis along with DDD
Energy,  Inc. Each  partnership's  working interest amounts to 2.5% of the total
investment  made by such  partnership  and DDD Energy,  Inc. for the partnership
formed  in  1997,  3% for  the  partnership  formed  in  1996  and  5%  for  the
partnerships  formed in 1995 and 1994. Each partnership  invests in projects and
prospects  undertaken by DDD Energy, Inc. in the year such partnership is formed
and all subsequent  development  of those  projects and prospects.  The terms of
each partnership  require the participants to contribute their share of required
capital contributions at the beginning of the year and any future cash calls, as
required.  All transactions between the partnerships and DDD Energy, Inc. are at
arm's-length.

NOTE L--MAJOR CUSTOMERS

     No customers  accounted for 10% or more of revenues  during the years 1997,
1996 or 1995.

     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 M--DISCONTINUED OPERATIONS

     On March 22, 1996, the Company's Board of Directors  unanimously  adopted a
plan  of  disposal  to  discontinue  the  Company's  gas  marketing  operations.
Accordingly,  the Company's  consolidated  financial  statements present the gas
marketing  operations  as  discontinued  operations  for all periods  presented.
Effective  August  1,  1996,  the  Company  assigned  substantially  all  of its
contracts to purchase and supply natural gas to a retail energy marketer.

     The loss from discontinued  operations  amounted to $988,000 and $1,196,000
for the years ended  December 31, 1996 and 1995, net of an income tax benefit of
$580,000 for 1996 and $703,000 for 1995.  At December 31, 1995,  the Company had
fixed price gas sales contracts which were generally below the estimated  market
price at which the Company could  purchase gas supply and  transportation.  Then
current  market  pricing  models were used to estimate the market price at which
the Company could  purchase gas supply and  transportation  in the future.  Such
models were used to estimate the loss related to future contractual  commitments
at  December  31,  1995.  During the first  seven  months of 1996,  the  Company
continued to deliver gas to customers  under its existing  contracts.  Effective
August 1, 1996,  the gas marketing  operations  were disposed of. As a result of
changes in market  prices to purchase  gas supply,  an  additional  $988,000 was
recognized as a loss from discontinued operations in 1996. Such loss represented
the final charge related to the discontinued operations. The loss on disposal of
discontinued  operations recorded as of December 31, 1995, was $252,000,  net of
an income tax benefit of $148,000, and included costs such as severance benefits
and estimated  personnel  costs to continue to honor the  Company's  obligations
until the gas marketing contracts were transferred or terminated.

     Revenue from the discontinued operations was $13,116,000 for the year ended
December  31,  1995.  No  assets or  liabilities  relating  to the  discontinued
operations remained at December 31, 1997.

Note N--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.

Note Q--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."

     OIL AND GAS RESERVES:  Proved reserves  represent  estimated  quantities of
crude oil,  condensate,  natural gas 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 crude oil (including  condensate and natural gas liquids)
and  natural  gas  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 Miller and Lents, Ltd. and Forrest A.
Garb &  Associates,  Inc.  at December  31,  1997 and Miller and Lents,  Ltd. at
December 31,  1996,  and by Forrest A. Garb &  Associates,  Inc. at December 31,
1995. 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.

     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.

     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 Financial  Accounting  Standards  Board  ("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  be
anticipated.

                    upon the  exercise of this  Warrant  Certificate;  provided,
                    however, that the Company shall pay with respect to any such
                    fraction of a Share an amount of cash based upon the current
                    public  market  value (or book  value,  if there shall be no
                    public  market value) for Shares  purchasable  upon exercise
                    hereof,  as determined in accordance with  subparagraph I of
                    Section 10 hereof; and

               C.   the Company may deem and treat the person in whose name this
                    Warrant  Certificate  is registered as the absolute true and
                    lawful owner hereof for all purposes whatsoever.

          4.   The  Company   shall   maintain   books  for  the   transfer  and
               registration of Warrants.  Upon the transfer of any Warrants, the
               Company shall issue and register the Warrants in the names of the
               new  Holders.  The  Warrants  shall  be  signed  manually  by the
               Chairman,   Chief  Executive  Officer,   President  or  any  Vice
               President of the Company.  The Company shall transfer,  from time
               to time, any outstanding Warrants upon the books to be maintained
               by the  Company  for such  purpose  upon  surrender  thereof  for
               transfer   properly   endorsed  or   accompanied  by  appropriate
               instructions  for  transfer.  Upon any  transfer,  a new  Warrant
               Certificate shall be issued to the transferee and the surrendered
               Warrants  shall  be  canceled  by the  Company.  Warrants  may be
               exchanged at the option of the Holder,  when  surrendered  at the
               office of the Company,  for another Warrant, or other Warrants of
               different  denominations,  of like tenor and  representing in the
               aggregate the right to purchase a like number of Shares.  Subject
               to the terms of this Warrant Certificate, upon such surrender and
               payment  of the  purchase  price,  the  Company  shall  issue and
               deliver with all reasonable dispatch to or upon the written order
               of the Holder of such  Warrants and in such name or names as such
               Holder may  designate,  a  certificate  or  certificates  for the
               number of full  Shares so  purchased  upon the  exercise  of such
               Warrants.  Such  certificate or  certificates  shall be deemed to
               have been issued and any person so designated to be named therein
               shall be  deemed  to have  become  the  holder  of record of such
               Shares  as of the  date of the  surrender  of such  Warrants  and
               payment of the purchase price; provided, however, that if, at the
               date of surrender and payment,  the transfer  books of the Shares
               shall  be  closed,  the  certificates  for the  Shares  shall  be
               issuable  as of the date on which such books  shall be opened and
               until such date the Company shall be under no duty to deliver any
               certificate for such Shares;  provided,  further,  however,  that
               such  transfer  books,  unless  otherwise  required  by law or by
               applicable rule of any national securities exchange, shall not be
               closed  at any one  time for a period  longer  than 20 days.  The
               rights  of  purchase   represented   by  the  Warrants  shall  be
               exercisable,  at  the  election  of  the  Holders,  either  as an
               entirety or from time to time for part only of the Shares.

          5.   The Company will pay any documentary stamp taxes  attributable to
               the initial  issuance of the Shares issuable upon the exercise of
               the Warrants;  provided,  however,  that the Company shall not be
               required  to pay any tax or taxes which may be payable in respect
               of any  transfer  involved  in the  issuance  or  delivery of any
               certificates  for  Shares in a name other than that of the Holder
               in respect of which such Shares are issued,  and in such case the
               Company shall not be required to issue or deliver any certificate
               for Shares or any Warrant  until the person  requesting  the same
               has paid to the Company the amount of such tax or has established
               to the Company's satisfaction that such tax has been paid.

          6.   In case the Warrant Certificate shall be mutilated,  lost, stolen
               or  destroyed,  the  Company  may, in its  discretion,  issue and
               deliver in exchange and substitution for and upon cancellation of
               the mutilated Warrant Certificate, or in lieu of and substitution
               for the Warrant  Certificate,  lost,  stolen or destroyed,  a new
               Warrant  Certificate of like tenor and representing an equivalent
               right or interest, but only upon receipt of evidence satisfactory
               to  the  Company  of  such  loss,  theft  or  destruction  and an
               indemnity, if requested, also satisfactory to it.

          7.   The Company warrants that there have been reserved, and covenants
               that at all times in the  future it shall keep  reserved,  out of
               the  authorized  and unissued  Common  Stock,  a number of Shares
               sufficient  to provide for the exercise of the rights or purchase
               represented by this Warrant Certificate.  The Company agrees that
               all Shares  issuable upon  exercise of the Warrants  shall be, at
               the time of delivery of the certificates for such Shares, validly
               issued and outstanding,  fully paid and  non-assessable  and that
               the  issuance  of such  Shares  will not give rise to  preemptive
               rights in favor of existing shareholders.

          8.   As used herein,  the term  "Exercise  Rate" shall mean the number
               and kind of  shares of  capital  stock of the  Company  which the
               Holder of this  Warrant  shall be  entitled  from time to time to
               receive for each $1,000.00 of warrant  exercise  payment.  Unless
               and until an adjustment  thereof shall be required as hereinafter
               provided,  the  Exercise  Rate  shall be 24.39  shares  of Common
               Stock.

          9.   The term  "Exercise  Price"  shall  mean the  price  obtained  by
               dividing  $1,000.00  by the  number  of shares  constituting  the
               Exercise Rate in effect at the time for such amount.

          10.  The  Exercise  Rate in  effect  any  time  shall  be  subject  to
               adjustment as follows:

               A.   Whenever  the  Company  shall (i) pay a  dividend  on Common
                    Stock in shares of its  Common  Stock,  (ii)  subdivide  its
                    outstanding  shares  of  Common  Stock,  (iii)  combine  its
                    outstanding  shares of Common Stock into a smaller number of
                    shares, or (iv) issue by  reclassification  of its shares of
                    Common Stock (including any  reclassification  in connection
                    with a  consolidation  or merger in which the Company is the
                    continuing  corporation)  any shares,  the Exercise  Rate in
                    effect at the time of the record  date for such  dividend or
                    of the effective  date of such  subdivision,  combination or
                    reclassification  shall be proportionately  adjusted so that
                    the  Holder of this  Warrant  exercising  it after such time
                    shall be entitled  to receive  the total  number and kind of
                    shares  which bear the same  proportion  to the total issued
                    and  outstanding  Common  Stock of the  Company  immediately
                    after  such time as the  proportion  he would have owned and
                    have been  entitled  to  receive  immediately  prior to such
                    time.

               B.   Whenever the Company  shall issue any shares of Common Stock
                    other than:

                    (i)  shares   issued   in   a   transaction   described   in
                         subparagraph H of this Paragraph 10; and

                    (ii) shares issued upon exercise or conversion of securities
                         of the type  referred  to in  subparagraphs  E and F of
                         this  Paragraph  10 or  shares  issued,  subdivided  or
                         combined in transactions  described in subparagraph (A)
                         of this  Paragraph  10 if and to the  extent  that  the
                         Exercise  Rate  shall  have  been  previously  adjusted
                         pursuant  to the  terms  of  this  subparagraph  (B) or
                         subparagraph  (A) of this  Paragraph  10 as a result of
                         the  issuance,   subdivision  or  combination  of  such
                         securities;

                    at a price per share which is less than the  current  public
                    market value of a share of Common  Stock,  the Exercise Rate
                    in  effect  immediately  prior  to such  issuance  shall  be
                    adjusted by  multiplying  such  Exercise Rate by a fraction,
                    the  numerator  of which  shall be the  number  of shares of
                    Common Stock outstanding  immediately prior to such issuance
                    plus the  number of  additional  shares  of Common  Stock so
                    issued,  and the denominator of which shall be the number of
                    Shares of Common Stock outstanding immediately prior to such
                    issuance plus the number of shares of Common Stock which the
                    fair value of the consideration  received by the Company for
                    the total  number  of  additional  shares  so  issued  would
                    purchase  at a price  equal  to the  current  public  market
                    value.

               C.   Whenever  the  Company  shall  pay  a  dividend  or  make  a
                    distribution  (other than in a transaction  which results in
                    an equivalent  adjustment pursuant to other subparagraphs of
                    this  Paragraph 10) generally to holders of its Common Stock
                    or  evidences  of  its  indebtedness  or  assets  (excluding
                    dividends paid in, or distributions of cash to the extent of
                    current  income  or  earned  surplus  of  the  Company),  or
                    securities  of the Company,  or rights to  subscribe  for or
                    purchase  securities  of the Company,  the Exercise  Rate in
                    effect  immediately  prior  to such  distribution  shall  be
                    adjusted by  multiplying  such  Exercise Rate by a fraction,
                    the  numerator  of which  shall be the then  current  public
                    market  value,  if  any,  per  share  of  the  Common  Stock
                    receiving such dividend or  distribution  or, if there shall
                    be no such current public market value,  then the book value
                    per  share  as of the  close  of the  month  preceding  such
                    distribution,  and the  denominator  of  which  shall be the
                    numerator  less the fair market  value of the portion of the
                    assets,  or the  evidences  of  indebtedness  or rights,  so
                    distributed   which  is   applicable  to  each  such  share;
                    provided,  however,  if as a result of such  adjustment  the
                    Exercise Price would be a --------  ------- negative figure,
                    such adjustment shall be modified so that the Exercise Price
                    after such adjustment is $.01 per share.

               D.   Whenever the Company shall issue by  reclassification of its
                    shares of Common  Stock any  shares of stock,  the  Exercise
                    Rate in effect  immediately  prior to such issuance shall be
                    proportionately  adjusted so that the Holder of this Warrant
                    exercising  it after such time shall be entitled to receive,
                    the  number  and kind of  shares  which,  when  added to the
                    number of shares of such kind exercisable hereunder prior to
                    such  issue,  would  entitle  the  Holder  hereof,  upon the
                    exercise  hereof in full, to purchase an amount of shares of
                    such  kind  which  bears  the same  proportion  to the total
                    issued and  outstanding  capital stock of the Company as the
                    proportion  he would  have owned and have been  entitled  to
                    receive  immediately  prior to such issue. In the event that
                    at any time, as a result of an  adjustment  made pursuant to
                    this  paragraph  10, the Holder of this Warrant shall become
                    entitled upon exercise  thereof to receive any shares of the
                    Company  other  than  shares  of  its  Common  Stock,   then
                    thereafter  the  number of such other  shares so  receivable
                    upon exercise of this Warrant shall be subject to adjustment
                    from  time  to time  in a  manner  and on  terms  as  nearly
                    equivalent as  practicable  to the  provisions  contained in
                    this Paragraph 10 in the respect of the Common Stock.

               E.   For  purposes  of  the  adjustments   provided  for  in  the
                    foregoing  subparagraphs  of this  Paragraph  10,  if at any
                    time,  the Company shall issue any rights or options for the
                    purchase of, or stock or other  securities  convertible into
                    Common Stock,  (such  convertible  stock or securities being
                    herein referred to as "Convertible  Securities") the Company
                    shall be deemed to have  issued at the time of the  issuance
                    of such  rights or options  or  Convertible  Securities  the
                    maximum  number  of shares of  Common  Stock  issuable  upon
                    exercise  or  conversion  thereof  and to have  received  as
                    consideration  for the  issuance  of such  shares  an amount
                    equal  to the  amount  of  cash  and  fair  value  of  other
                    consideration,  if  any,  received  by the  Company  for the
                    issuance   of  such   rights  or  options   or   Convertible
                    Securities, plus, in the case of such options or rights, the
                    minimum   amounts   of  cash   and   fair   value  of  other
                    consideration,  if any,  payable  to the  Company  upon  the
                    exercise  of such  options  or  rights  and,  in the case of
                    Convertible Securities, the minimum amounts of cash and fair
                    value  of  other  consideration,  if  any,  payable,  to the
                    Company.

               F.   For purposes of the adjustment  provided for in subparagraph
                    B above,  if at any time the Company  shall issue any rights
                    or options for the purchase of Convertible  Securities,  the
                    Company  shall be deemed  to have  issued at the time of the
                    issuance of such  rights or options  the  maximum  number of
                    shares of Common Stock issuable upon conversion of the total
                    amount of Convertible  Securities  covered by such rights or
                    options  and to  have  received  as  consideration  for  the
                    issuance  of such  shares an amount  equal to the  amount of
                    cash and the amount of fair value of other consideration, if
                    any, received by the Company for the issuance of such rights
                    or options,  plus the minimum amounts of cash and fair value
                    of other consideration,  if any, payable to the Company upon
                    the  exercise  of such  rights or options and payable to the
                    Company on conversion of such Convertible Securities.

               G.   Anything  in  subparagraph  E or F  above  to  the  contrary
                    notwithstanding, whenever the Company shall issue any shares
                    (other than on exercise of this  Warrant)  upon  exercise of
                    any rights or options or upon  conversion of any Convertible
                    Securities  and if the  Exercise  Rate shall not  previously
                    have been adjusted upon the issuance of such rights, options
                    or  Convertible  Securities,  the  computation  described in
                    subparagraph  B above  shall be made and the  Exercise  Rate
                    adjusted in  accordance  with the  provisions  thereof  (the
                    shares  so  issued   being   deemed  for  purposes  of  such
                    computation  to have been  issued at a price per share equal
                    to the amount of cash and fair value of other consideration,
                    if any, properly  attributable to one such share received by
                    the Company  upon  issuance  and  exercise of such rights or
                    options  or  sale  and   conversion   of  such   Convertible
                    Securities  (and upon  issuance  of any  rights  or  options
                    pursuant to which such Convertible  Securities may have been
                    sold).

               H.   Anything   in   this    Paragraph   10   to   the   contrary
                    notwithstanding,  no  adjustment  in the  Exercise  Rate  or
                    Exercise Price shall be made in connection with:

                    (i)  Convertible Securities issued pursuant to the Company's
                         qualified or non-qualified  Employee Stock Option Plans
                         or  any  other  bona  fide  employee  benefit  plan  or
                         incentive  arrangement,  adopted  or  approved  by  the
                         Company's  Board of Directors or shares of Common Stock
                         issued  pursuant  to  the  exercise  of any  rights  or
                         options granted  pursuant to said plans or arrangements
                         (but only to the extent  that the  aggregate  number of
                         shares  excluded by the Clause (i) and issued after the
                         date  hereof  shall  not  exceed  15% of the  Company's
                         Common  Stock  outstanding  at the  time  of  any  such
                         issuance); and

                    (ii) The issuance of any shares of Common Stock  pursuant to
                         the exercise of Convertible  Securities  outstanding as
                         of the date hereof including  without  limitation,  the
                         conversion of any Warrant  issued in the same placement
                         of securities pursuant to which this Warrant was issued
                         by the Company.

               I.   For purposes of this Paragraph 10, the current public market
                    value of a share of Common Stock on any date shall be deemed
                    to be the  arithmetical  average of the following prices for
                    such of the thirty (30) business days immediately  preceding
                    such day as shall be available: (i) for any of the such days
                    on which the  Common  Stock  shall be  listed on a  national
                    securities exchange,  the last sale price on such day or, if
                    there  shall have been no sale on such day,  the  average of
                    the  closing bid and asked  prices on such  exchange on such
                    day, or (ii) for any of such days on which the Common  Stock
                    shall not be listed on a national  securities  exchange  but
                    shall be included in the National  Association of Securities
                    Dealers Automated  Quotation System ("NASDAQ"),  the average
                    of the  closing  bid and asked  prices on such day quoted by
                    brokers and dealers making a market in NASDAQ,  furnished by
                    any member of the New York Stock  Exchange  selected  by the
                    Company for that  purpose,  or (iii) for any of such days on
                    which the Common  Stock shall not be so listed on a national
                    securities  exchange  or  included  in  NASDAQ  but shall be
                    quoted by three  brokers  regularly  making a market in such
                    shares in the  over-the-counter  market,  the average of the
                    closing bid and asked  prices on such day,  furnished by any
                    member  of the  New  York  Stock  Exchange  selected  by the
                    Company for that purpose,  or (iv) for any days on which the
                    information  described in items (i),  (ii) or (iii) above is
                    unavailable, the book value per share of the Common Stock as
                    determined in accordance with generally accepted  accounting
                    principles;  provided,  however, in its discretion the Board
                    may make an  appropriate  reduction in the  "current  public
                    market value" based upon any applicable trading restrictions
                    to particular shares of Common Stock.

               J.   Anything   in   this    Paragraph   10   to   the   contrary
                    notwithstanding, no adjustment in the Exercise Rate shall be
                    required unless such adjustment would require an increase or
                    decrease  of at least 1% in such  rate;  provided,  however,
                    that any adjustments  which by reason of this subparagraph J
                    are not  required  to be made shall be carried  forward  and
                    taken into  account in making  subsequent  adjustments.  All
                    calculations  under  the  Paragraph  10 shall be made to the
                    nearest cent or to the nearest  one-hundredth of a share, as
                    the case may be.

               K.   No  adjustment  in the  Exercise  Rate  shall  be  made  for
                    purposes of  subparagraphs  B and C of this  Paragraph 10 if
                    such adjustment would result in an increase in such Exercise
                    Price or decrease in the Exercise  Rate except that,  in the
                    case of any  Convertible  Securities  in respect of which an
                    adjustment  has  previously  been made under  subparagraph B
                    above and which  has  expired  or  otherwise  been  canceled
                    without exercise of the rights or options evidenced thereby,
                    such previous adjustment shall be reversed.

               L.   Before  taking any action  which could  cause an  adjustment
                    pursuant to this  Paragraph 10 reducing  the Exercise  Price
                    per share  below  the then par value (if any) of the  shares
                    covered hereby,  the Company will take any corporate  action
                    which may be necessary in order that the Company may validly
                    and  legally  issue at the  Exercise  Price  as so  adjusted
                    shares that are fully paid and non-assessable.

               M.   The  number  of  shares  of  capital  stock  of the  Company
                    outstanding at any given time shall not include shares owned
                    or  held  by or for  the  account  of the  Company,  and the
                    disposition  of any such shares shall be considered an issue
                    or sale of such shares for the  purposes  of this  Paragraph
                    10.

               N.   If any event occurs as to which the other provisions of this
                    Paragraph 10 are not strictly applicable but the lack of any
                    adjustment  would not fairly protect the purchase  rights of
                    the  Holder of this  Warrant  in  accordance  with the basic
                    intent and  principles  of such  provisions,  or if strictly
                    applicable  would not fairly protect the purchase  rights of
                    the  Holder of this  Warrant  in  accordance  with the basic
                    intent and principles of such  provisions,  then the Company
                    shall  appoint  a  firm  of  independent   certified  public
                    accountants  (which shall not be the regular auditors of the
                    Company) of recognized  national standing,  which shall give
                    their  opinion  upon  the  adjustment,  if  any,  on a basis
                    consistent with the basic intent and principles  established
                    in the other  provisions of this Paragraph 10,  necessary to
                    preserve,  without  dilution,  the  exercise  rights  of the
                    registered  Holder of this  Warrant.  Upon  receipt  of such
                    opinion,  the Company shall  forthwith make the  adjustments
                    described  therein.  In taking  any  action  or  making  any
                    determination pursuant to the provisions of this Section 10,
                    the Company and its Board of Directors  shall, at all times,
                    exercise reasonable judgment and act in good faith.

               O.   Upon any adjustment of any Exercise  Rate,  then and in each
                    such case,  the Company shall  promptly  deliver a notice to
                    the  registered  Holder of this Warrant,  which notice shall
                    state the Exercise  Price and Exercise Rate  resulting  from
                    such adjustment and the increase or decrease, if any, in the
                    number of shares purchasable at such price upon the exercise
                    hereof,  setting  forth in  reasonable  detail the method of
                    calculation  and the facts upon which  such  calculation  is
                    based.

               P.   In the case of the  issuance  of shares  of Common  Stock or
                    Convertible  Securities for a  consideration  in whole or in
                    part,  other than cash,  the  consideration  other than cash
                    shall be  deemed  to be the fair  market  value  thereof  as
                    reasonably   determined  in  good  faith  by  the  Board  of
                    Directors of the Company (regardless of accounting treatment
                    thereof);  provided,  however,  that if  such  consideration
                    consists of the  cancellation  of debt issued by the Company
                    the  consideration  shall be  deemed  to be the  amount  the
                    Company received upon issuance of such debt (gross proceeds)
                    plus  accrued  interest  and, in the case of original  issue
                    discount or zero coupon indebtedness,  accreted value to the
                    date of such cancellation,  but not including any premium or
                    discount  at which  the debt  may then be  trading  or which
                    might otherwise be appropriate for such class of debt;

               Q.   The Company  shall not issue any shares of its capital stock
                    (other than Common Stock) at or for  consideration  which is
                    less than fair value determined by the Board of Directors of
                    the Company in light of all  circumstances  surrounding such
                    issuance.

          11.  In the case:

               A.   The Company  shall declare any dividend or  distribution  on
                    its Common Stock (or on any other shares which the Holder of
                    this Warrant may become  entitled to receive  upon  exercise
                    hereof); or

               B.   The Company  shall  authorize the issuance to holders of its
                    Common  Stock (or on any other  shares  which the  Holder of
                    this Warrant may become  entitled to receive  upon  exercise
                    hereof) any subscription rights or warrants; or

               C.   Of  any  subdivision,  combination  or  reclassification  of
                    shares of Common  Stock of the Company (or any shares of the
                    Company  which  are  subject  to  this  Warrant),  or of any
                    proposed  consolidation or merger to which the Company is to
                    be a party and for which the approval of any shareholders of
                    the Company is required, or of the proposed sale or transfer
                    of all or substantially all of the assets of the Company; or
                    D. Of the  proposed  voluntary or  involuntary  dissolution,
                    liquidation, or winding up of the Company; or

               E.   The Company proposes to effect any transaction not specified
                    above which would require an adjustment of the Exercise Rate
                    pursuant to Paragraph 10 hereof;

               then the  Company  shall  cause to be mailed to  Holders  of this
               Warrant, at least ten (10) days prior to the applicable record or
               other  date  hereinafter  specified,  a  notice  describing  such
               transaction  in  reasonable  detail,  specifying  the  character,
               amount and terms of all  securities  and the  amounts of cash and
               other property,  if any, involved in such transaction and stating
               (i) the date as of which the holders of Common Stock (or any such
               other  shares)  of  record to be  entitled  to  receive  any such
               dividend, distribution,  rights, or warrants is to be determined,
               or (ii)  the date of which  any  such  subdivision,  combination,
               reclassification,    consolidation,   merger,   sale,   transfer,
               dissolution,  liquidation,  winding up, or other  transaction  is
               expected  to  become  effective,  and the  date as of which it is
               expected  that holders of Common Stock (or any such other shares)
               of record shall be entitled to exchange  the same for  securities
               or other property, if any, deliverable upon such transaction.

          12.  The  Company  covenants  and  agrees  that it will  not  merge or
               consolidate  with or into or sell or  otherwise  transfer  all or
               substantially  all of its  assets  to any  other  corporation  or
               entity  unless at the time of or prior to such  transaction  such
               other  corporation or other entity shall expressly  assume all of
               the liabilities and obligations of the Company under this Warrant
               and (without  limiting the  generality  of the  foregoing)  shall
               expressly agree that the Holder of this Warrant shall  thereafter
               have the  right  (subject  to  subsequent  adjustment  as  nearly
               equivalent  as  practicable  to the  adjustments  provided for in
               Paragraph  10 of this  Warrant) to receive  upon the  exercise of
               this  Warrant  the  number  and kind of shares of stock and other
               securities  and property  receivable  upon such  transaction by a
               Holder of the  number  and kind of shares  which  would have been
               receivable upon the exercise of this Warrant immediately prior to
               such transactions.

          13.  The Holder of this Warrant  Certificate,  each transferee  hereof
               and any holder and  transferee of any Shares,  by his  acceptance
               thereof,  agrees that (i) no public  distribution  of Warrants or
               shares will be made in violation of the Act, and (ii) during such
               period as the delivery of a  prospectus  with respect to Warrants
               or Shares may be required by the Act, no public  distribution  of
               Warrants or Shares will be made in a manner or on terms different
               from those set forth in, or  without  delivery  of, a  prospectus
               then  meeting  the  requirements  of Section 10 of the Act and in
               compliance with all applicable  state securities laws. The Holder
               of this Warrant  Certificate and each  transferee  hereof further
               agrees that if any  distribution of any of the Warrants or Shares
               is  proposed to be made by them  otherwise  than by delivery of a
               prospectus  meeting  the  requirements  of Section 10 of the Act,
               such action shall be taken only after  submission  to the Company
               of an opinion of  counsel,  reasonably  satisfactory  in form and
               substance  to the  Company's  counsel,  to the  effect  that  the
               proposed  distribution  will not be in violation of the Act or of
               applicable state law. Furthermore, it shall be a condition to the
               transfer of the Warrants that any transferee  thereof  deliver to
               the Company his written  agreement  to accept and be bound by all
               of  the  terms  and   conditions   contained   in  this   Warrant
               Certificate.

          14.  This Warrant  Certificate  shall be  exercisable  only during the
               continuance  of the  Holder's  employment  at the  Company or its
               subsidiaries, except that:

               A.   If the Holder  ceases to be an employee at the Company (or a
                    subsidiary  of the  Company)  for any  reason  other than by
                    death  or  disability,   this  Warrant  Certificate  may  be
                    exercised by Holder,  to the extent that it was  exercisable
                    at the date of termination, at any time within 90 days after
                    the date Holder ceases to be an employee, but not later than
                    November  19,  2002  except  that,  in case of his  death or
                    disability  within that  three-month  period,  this  Warrant
                    Certificate may be exercised as provided in subparagraph (b)
                    below.

               B.   If the Holder dies or becomes disabled during  employment or
                    within the  three-month  period  referred to in subparagraph
                    (a) above, this Warrant Certificate may be exercised, to the
                    extent that it was exercisable by the Holder at the date of:

                    (i)  death, by the person or persons to whom Holder's rights
                         under this Warrant  Certificate  pass by will or by the
                         laws of descent and distribution or

                    (ii) disability, by the Holder's legal representative,

                    at any time within one year after the date of Holder's death
                    or disability, but not later than November 19, 2002.

               The  determination  by the  Company's  Board of  Directors of the
               reason  for  termination  of the  Holder's  employment  shall  be
               binding and conclusive on the Holder.

          15.  Except only as  specifically  provided  elsewhere in this Warrant
               Certificate,  the Warrants shall not be exercisable  prior to the
               dates set forth below except in the amounts set forth below:

               A.   As of the date  hereof,  up to a total  of 20% of the  total
                    warrants represented hereby may be exercised.

               B.   The remaining 80% become  exercisable  on November 19, 2000,
                    or if earlier,  in  incremental  installments  of 20% of the
                    total  number  of  warrants   represented  hereby  for  each
                    two-point  increase in the closing price of the Common Stock
                    above $41.00 per share which is  maintained  or exceeded for
                    10 consecutive trading days.

          16.  In the  event  the  Company  shall  be a  party  to  any  merger,
               consolidation or corporate  reorganization as the result of which
               the Company is the surviving  corporation,  the rights and duties
               of the  Participants and the Company shall not be affected in any
               manner  except as specified in this Warrant  Certificate.  In the
               event the  Company  shall  sell all or  substantially  all of its
               assets  or  shall  be a  party  to  a  merger,  consolidation  or
               corporate  reorganization,  as the  result of which  the  Company
               shall  not be the  surviving  organization,  or in the  event any
               other corporation makes a successful tender or exchange offer for
               more  than  50%  of  the  stock  of the  Company  (the  surviving
               corporation,  purchaser, or tendering corporation being hereafter
               collectively  referred to as the  "purchaser" and the transaction
               being hereinafter  referred to the "purchase"),  and the Board of
               Directors  obtains the  agreement of the  purchaser to assume the
               obligations   of  the  Company  under  the  Holder's   employment
               agreement  with the  Company,  then the  rights and duties of the
               Holder and the Company (as assumed by the purchaser) shall not be
               affected  in any  manner  except  as  specified  in this  Warrant
               Certificate.  If the  Company  is  purchased  and  the  Board  of
               Directors  does not obtain such  agreement  of the  purchaser  to
               assume such  obligations  on or before the date of such purchase,
               all unvested  portions of all Holder's  warrants  hereunder  that
               have not been  forfeited as of the date of such purchase shall be
               accelerated and shall be immediately exercisable by the Holder.

          17.  No reload  warrants  shall be granted to the Holder upon exercise
               of the Warrants.

Certificate No. ----------

     This Warrant Certificate  certifies that  --------------- is the registered
holder  ("Holder")  of  -----------------------------  (--------)  Common  Stock
Purchase  Warrants  (the  "Warrants")  to purchase  shares of the $.01 par value
common stock,  ("Common  Stock") of SEITEL,  INC., a Delaware  corporation  (the
"Company").  Subject to Section 15 hereof,  each  Warrant  enables the Holder to
purchase from the Company at any time, on and after  November 20, 1997 and until
5:00 p.m.,  Houston,  Texas, local time on November 19, 2002, one fully paid and
non-assessable  share of Common Stock ("Share") upon  presentation and surrender
of this Warrant Certificate and upon payment of the purchase price of $41.00 per
Share.  Payment shall be made in lawful money of the United States of America by
certified  check  payable  to the  Company at its  principal  office at 50 Briar
Hollow Lane, West, 7th Floor,  Houston,  Texas, 77027. As hereinafter  provided,
the  purchase  price and number of Shares  purchasable  upon the exercise of the
Warrants are subject to modification or adjustment upon the happening of certain
events.

          FOR ALL OTHER PURPOSES  STATED HEREIN,  THE COMPANY MAY DEEM AND TREAT
     THE PERSON IN WHOSE NAME THIS  WARRANT  CERTIFICATE  IS  REGISTERED  AS THE
     ABSOLUTE TRUE AND LAWFUL OWNER HEREOF FOR ALL PURPOSES WHATSOEVER.

          1.   Upon surrender to the Company,  this Warrant  Certificate  may be
               exchanged for another Warrant Certificate or Warrant Certificates
               evidencing a like aggregate  number of Warrants.  If this Warrant
               Certificate  shall be  exercised  in part,  the  Holder  shall be
               entitled  to  receive  upon  surrender   hereof  another  Warrant
               Certificate  or  Warrant  Certificates  evidencing  the number of
               Warrants not exercised.

          2.   No Holder shall be deemed to be the holder of Common Stock or any
               other  securities of the Company that may at any time be issuable
               on the  exercise  hereof  for  any  purpose  nor  shall  anything
               contained  herein be  construed  to confer upon the Holder any of
               the rights of a  shareholder  of the Company or any right to vote
               for the  election of  directors  or upon any matter  submitted to
               shareholders  at any  meeting  thereof  or to  give  or  withhold
               consent to any corporate action (whether upon any reorganization,
               issuance  of  stock,  reclassification  or  conversion  of stock,
               change  of  par  value,  consolidation,  merger,  conveyance,  or
               otherwise)  or to  receive  notice  of  meetings  or  to  receive
               dividends or  subscription  rights or  otherwise  until a Warrant
               shall have been exercised and the Common Stock  purchasable  upon
               the exercise thereof shall have become issuable.

          3.   Each  Holder  consents  and agrees with the Company and any other
               Holder that:

               A.   this Warrant  Certificate is exercisable in whole or in part
                    by the Holder in person or by attorney  duly  authorized  in
                    writing at the principal office of the Company.

               B.   anything herein to the contrary notwithstanding, in no event
                    shall the Company be obligated to issue Warrant Certificates
                    evidencing  other than a whole  number of  Warrants or issue
                    certificates  evidencing other than a whole number of Shares
                    upon the  exercise of this  Warrant  Certificate;  provided,
                    however, that the Company shall pay with respect to any such
                    fraction of a Share an amount of cash based upon the current
                    public  market  value (or book  value,  if there shall be no
                    public  market value) for Shares  purchasable  upon exercise
                    hereof,  as determined in accordance with  subparagraph I of
                    Section 10 hereof; and

               C.   the Company may deem and treat the person in whose name this
                    Warrant  Certificate  is registered as the absolute true and
                    lawful owner hereof for all purposes whatsoever.

          4.   The  Company   shall   maintain   books  for  the   transfer  and
               registration of Warrants.  Upon the transfer of any Warrants, the
               Company shall issue and register the Warrants in the names of the
               new  Holders.  The  Warrants  shall  be  signed  manually  by the
               Chairman,   Chief  Executive  Officer,   President  or  any  Vice
               President of the Company.  The Company shall transfer,  from time
               to time, any outstanding Warrants upon the books to be maintained
               by the  Company  for such  purpose  upon  surrender  thereof  for
               transfer   properly   endorsed  or   accompanied  by  appropriate
               instructions  for  transfer.  Upon any  transfer,  a new  Warrant
               Certificate shall be issued to the transferee and the surrendered
               Warrants  shall  be  canceled  by the  Company.  Warrants  may be
               exchanged at the option of the Holder,  when  surrendered  at the
               office of the Company,  for another Warrant, or other Warrants of
               different  denominations,  of like tenor and  representing in the
               aggregate the right to purchase a like number of Shares.  Subject
               to the terms of this Warrant Certificate, upon such surrender and
               payment  of the  purchase  price,  the  Company  shall  issue and
               deliver with all reasonable dispatch to or upon the written order
               of the Holder of such  Warrants and in such name or names as such
               Holder may  designate,  a  certificate  or  certificates  for the
               number of full  Shares so  purchased  upon the  exercise  of such
               Warrants.  Such  certificate or  certificates  shall be deemed to
               have been issued and any person so designated to be named therein
               shall be  deemed  to have  become  the  holder  of record of such
               Shares  as of the  date of the  surrender  of such  Warrants  and
               payment of the purchase price; provided, however, that if, at the
               date of surrender and payment,  the transfer  books of the Shares
               shall  be  closed,  the  certificates  for the  Shares  shall  be
               issuable  as of the date on which such books  shall be opened and
               until such date the Company shall be under no duty to deliver any
               certificate for such Shares;  provided,  further,  however,  that
               such  transfer  books,  unless  otherwise  required  by law or by
               applicable rule of any national securities exchange, shall not be
               closed  at any one  time for a period  longer  than 20 days.  The
               rights  of  purchase   represented   by  the  Warrants  shall  be
               exercisable,  at  the  election  of  the  Holders,  either  as an
               entirety or from time to time for part only of the Shares.

          5.   The Company will pay any documentary stamp taxes  attributable to
               the initial  issuance of the Shares issuable upon the exercise of
               the Warrants;  provided,  however,  that the Company shall not be
               required  to pay any tax or taxes which may be payable in respect
               of any  transfer  involved  in the  issuance  or  delivery of any
               certificates  for  Shares in a name other than that of the Holder
               in respect of which such Shares are issued,  and in such case the
               Company shall not be required to issue or deliver any certificate
               for Shares or any Warrant  until the person  requesting  the same
               has paid to the Company the amount of such tax or has established
               to the Company's satisfaction that such tax has been paid.

          6.   In case the Warrant Certificate shall be mutilated,  lost, stolen
               or  destroyed,  the  Company  may, in its  discretion,  issue and
               deliver in exchange and substitution for and upon cancellation of
               the mutilated Warrant Certificate, or in lieu of and substitution
               for the Warrant  Certificate,  lost,  stolen or destroyed,  a new
               Warrant  Certificate of like tenor and representing an equivalent
               right or interest, but only upon receipt of evidence satisfactory
               to  the  Company  of  such  loss,  theft  or  destruction  and an
               indemnity, if requested, also satisfactory to it.

          7.   The Company warrants that there have been reserved, and covenants
               that at all times in the  future it shall keep  reserved,  out of
               the  authorized  and unissued  Common  Stock,  a number of Shares
               sufficient  to provide for the exercise of the rights or purchase
               represented by this Warrant Certificate.  The Company agrees that
               all Shares  issuable upon  exercise of the Warrants  shall be, at
               the time of delivery of the certificates for such Shares, validly
               issued and outstanding,  fully paid and  non-assessable  and that
               the  issuance  of such  Shares  will not give rise to  preemptive
               rights in favor of existing shareholders.

          8.   As used herein,  the term  "Exercise  Rate" shall mean the number
               and kind of  shares of  capital  stock of the  Company  which the
               Holder of this  Warrant  shall be  entitled  from time to time to
               receive for each $1,000.00 of warrant  exercise  payment.  Unless
               and until an adjustment  thereof shall be required as hereinafter
               provided,  the  Exercise  Rate  shall be 24.39  shares  of Common
               Stock.

          9.   The term  "Exercise  Price"  shall  mean the  price  obtained  by
               dividing  $1,000.00  by the  number  of shares  constituting  the
               Exercise Rate in effect at the time for such amount.

          10.  The  Exercise  Rate in  effect  any  time  shall  be  subject  to
               adjustment as follows:

               A.   Whenever  the  Company  shall (i) pay a  dividend  on Common
                    Stock in shares of its  Common  Stock,  (ii)  subdivide  its
                    outstanding  shares  of  Common  Stock,  (iii)  combine  its
                    outstanding  shares of Common Stock into a smaller number of
                    shares, or (iv) issue by  reclassification  of its shares of
                    Common Stock (including any  reclassification  in connection
                    with a  consolidation  or merger in which the Company is the
                    continuing  corporation)  any shares,  the Exercise  Rate in
                    effect at the time of the record  date for such  dividend or
                    of the effective  date of such  subdivision,  combination or
                    reclassification  shall be proportionately  adjusted so that
                    the  Holder of this  Warrant  exercising  it after such time
                    shall be entitled  to receive  the total  number and kind of
                    shares  which bear the same  proportion  to the total issued
                    and  outstanding  Common  Stock of the  Company  immediately
                    after  such time as the  proportion  he would have owned and
                    have been  entitled  to  receive  immediately  prior to such
                    time.

               B.   Whenever the Company  shall issue any shares of Common Stock
                    other than:

                    (i)  shares   issued   in   a   transaction   described   in
                         subparagraph H of this Paragraph 10; and

                    (ii) shares issued upon exercise or conversion of securities
                         of the type  referred  to in  subparagraphs  E and F of
                         this  Paragraph  10 or  shares  issued,  subdivided  or
                         combined in transactions  described in subparagraph (A)
                         of this  Paragraph  10 if and to the  extent  that  the
                         Exercise  Rate  shall  have  been  previously  adjusted
                         pursuant  to the  terms  of  this  subparagraph  (B) or
                         subparagraph  (A) of this  Paragraph  10 as a result of
                         the  issuance,   subdivision  or  combination  of  such
                         securities;

               at a price per share which is less than the current public market
               value of a share of Common  Stock,  the  Exercise  Rate in effect
               immediately   prior  to  such  issuance   shall  be  adjusted  by
               multiplying  such Exercise  Rate by a fraction,  the numerator of
               which shall be the number of shares of Common  Stock  outstanding
               immediately  prior to such issuance plus the number of additional
               shares of Common Stock so issued,  and the  denominator  of which
               shall  be the  number  of  Shares  of  Common  Stock  outstanding
               immediately  prior to such  issuance plus the number of shares of
               Common Stock which the fair value of the  consideration  received
               by the  Company  for the  total  number of  additional  shares so
               issued  would  purchase at a price  equal to the  current  public
               market value.

          C.   Whenever the Company shall pay a dividend or make a  distribution
               (other  than in a  transaction  which  results  in an  equivalent
               adjustment  pursuant to other subparagraphs of this Paragraph 10)
               generally  to  holders of its Common  Stock or  evidences  of its
               indebtedness   or  assets   (excluding   dividends  paid  in,  or
               distributions  of cash to the extent of current  income or earned
               surplus of the Company),  or securities of the Company, or rights
               to  subscribe  for or purchase  securities  of the  Company,  the
               Exercise Rate in effect  immediately  prior to such  distribution
               shall  be  adjusted  by  multiplying  such  Exercise  Rate  by  a
               fraction, the numerator of which shall be the then current public
               market  value,  if any, per share of the Common  Stock  receiving
               such  dividend  or  distribution  or,  if there  shall be no such
               current public market value,  then the book value per share as of
               the  close of the  month  preceding  such  distribution,  and the
               denominator  of which shall be the numerator less the fair market
               value  of  the  portion  of  the  assets,  or  the  evidences  of
               indebtedness  or rights,  so  distributed  which is applicable to
               each  such  share;  provided,  however,  if as a  result  of such
               adjustment  the  Exercise  Price  would  be  a  --------  -------
               negative  figure,  such adjustment  shall be modified so that the
               Exercise Price after such adjustment is $.01 per share.

          D.   Whenever  the  Company  shall  issue by  reclassification  of its
               shares of Common Stock any shares of stock,  the Exercise Rate in
               effect    immediately   prior   to   such   issuance   shall   be
               proportionately  adjusted  so that  the  Holder  of this  Warrant
               exercising  it after such time shall be entitled to receive,  the
               number  and kind of shares  which,  when  added to the  number of
               shares of such kind  exercisable  hereunder  prior to such issue,
               would  entitle the Holder  hereof,  upon the  exercise  hereof in
               full,  to  purchase  an amount of shares of such kind which bears
               the same proportion to the total issued and  outstanding  capital
               stock of the  Company as the  proportion  he would have owned and
               have been entitled to receive immediately prior to such issue. In
               the event  that at any time,  as a result of an  adjustment  made
               pursuant to this  paragraph  10, the Holder of this Warrant shall
               become  entitled upon  exercise  thereof to receive any shares of
               the  Company  other  than  shares  of  its  Common  Stock,   then
               thereafter  the number of such other  shares so  receivable  upon
               exercise of this Warrant shall be subject to adjustment from time
               to  time  in a  manner  and on  terms  as  nearly  equivalent  as
               practicable to the  provisions  contained in this Paragraph 10 in
               the respect of the Common Stock.

          E.   For purposes of the  adjustments  provided  for in the  foregoing
               subparagraphs  of this  Paragraph 10, if at any time, the Company
               shall issue any rights or options for the  purchase  of, or stock
               or  other  securities   convertible  into  Common  Stock,   (such
               convertible  stock or  securities  being  herein  referred  to as
               "Convertible  Securities")  the  Company  shall be deemed to have
               issued at the time of the  issuance  of such rights or options or
               Convertible  Securities  the  maximum  number of shares of Common
               Stock  issuable upon  exercise or conversion  thereof and to have
               received  as  consideration  for the  issuance  of such shares an
               amount  equal  to the  amount  of cash  and  fair  value of other
               consideration,  if any,  received by the Company for the issuance
               of such rights or options or Convertible Securities, plus, in the
               case of such options or rights,  the minimum  amounts of cash and
               fair value of other consideration, if any, payable to the Company
               upon the  exercise of such  options or rights and, in the case of
               Convertible  Securities,  the  minimum  amounts  of cash and fair
               value of other consideration, if any, payable, to the Company.

          F.   For purposes of the  adjustment  provided for in  subparagraph  B
               above,  if at any time the  Company  shall  issue  any  rights or
               options for the purchase of Convertible  Securities,  the Company
               shall be deemed to have  issued  at the time of the  issuance  of
               such  rights or options  the  maximum  number of shares of Common
               Stock issuable upon conversion of the total amount of Convertible
               Securities covered by such rights or options and to have received
               as consideration  for the issuance of such shares an amount equal
               to the  amount  of cash  and the  amount  of fair  value of other
               consideration,  if any,  received by the Company for the issuance
               of such rights or options,  plus the minimum  amounts of cash and
               fair value of other consideration, if any, payable to the Company
               upon the  exercise  of such  rights or options and payable to the
               Company on conversion of such Convertible Securities.

          G.   Anything  in   subparagraph   E  or  F  above  to  the   contrary
               notwithstanding,  whenever  the  Company  shall  issue any shares
               (other  than on exercise of this  Warrant)  upon  exercise of any
               rights  or  options  or  upon   conversion  of  any   Convertible
               Securities  and if the Exercise  Rate shall not  previously  have
               been  adjusted  upon the  issuance  of such  rights,  options  or
               Convertible Securities, the computation described in subparagraph
               B  above  shall  be  made  and  the  Exercise  Rate  adjusted  in
               accordance  with the  provisions  thereof  (the  shares so issued
               being deemed for purposes of such computation to have been issued
               at a price per share  equal to the  amount of cash and fair value
               of other consideration, if any, properly attributable to one such
               share  received by the Company upon issuance and exercise of such
               rights or  options  or sale and  conversion  of such  Convertible
               Securities  (and upon issuance of any rights or options  pursuant
               to which such Convertible Securities may have been sold).

          H.   Anything in this Paragraph 10 to the contrary notwithstanding, no
               adjustment in the Exercise  Rate or Exercise  Price shall be made
               in connection with:

               (i)  Convertible  Securities  issued  pursuant  to the  Company's
                    qualified or  non-qualified  Employee  Stock Option Plans or
                    any  other  bona fide  employee  benefit  plan or  incentive
                    arrangement,  adopted or approved by the Company's  Board of
                    Directors or shares of Common  Stock issued  pursuant to the
                    exercise of any rights or options  granted  pursuant to said
                    plans  or  arrangements  (but  only to the  extent  that the
                    aggregate  number of shares  excluded  by the Clause (i) and
                    issued  after the date  hereof  shall not  exceed 15% of the
                    Company's  Common Stock  outstanding at the time of any such
                    issuance); and

               (ii) The issuance of any shares of Common  Stock  pursuant to the
                    exercise of  Convertible  Securities  outstanding  as of the
                    date hereof including without limitation,  the conversion of
                    any  Warrant  issued  in the same  placement  of  securities
                    pursuant to which this Warrant was issued by the Company.

          I.   For  purposes of this  Paragraph  10, the current  public  market
               value of a share of Common  Stock on any date  shall be deemed to
               be the  arithmetical  average of the following prices for such of
               the thirty (30) business days  immediately  preceding such day as
               shall be  available:  (i) for any of the such  days on which  the
               Common Stock shall be listed on a national  securities  exchange,
               the last sale  price on such day or, if there  shall have been no
               sale on such day, the average of the closing bid and asked prices
               on such  exchange  on such  day,  or (ii) for any of such days on
               which  the  Common  Stock  shall  not  be  listed  on a  national
               securities  exchange  but  shall  be  included  in  the  National
               Association  of Securities  Dealers  Automated  Quotation  System
               ("NASDAQ"),  the average of the  closing bid and asked  prices on
               such day quoted by brokers and dealers making a market in NASDAQ,
               furnished by any member of the New York Stock  Exchange  selected
               by the Company for that purpose, or (iii) for any of such days on
               which the  Common  Stock  shall  not be so  listed on a  national
               securities  exchange or included in NASDAQ but shall be quoted by
               three  brokers  regularly  making a market in such  shares in the
               over-the-counter market, the average of the closing bid and asked
               prices on such day, furnished by any member of the New York Stock
               Exchange  selected by the Company for that  purpose,  or (iv) for
               any days on which the information described in items (i), (ii) or
               (iii)  above is  unavailable,  the book  value  per  share of the
               Common Stock as determined in accordance with generally  accepted
               accounting principles;  provided,  however, in its discretion the
               Board may make an  appropriate  reduction in the "current  public
               market value" based upon any applicable  trading  restrictions to
               particular shares of Common Stock.

          J.   Anything in this Paragraph 10 to the contrary notwithstanding, no
               adjustment  in the  Exercise  Rate shall be required  unless such
               adjustment  would  require an increase or decrease of at least 1%
               in such rate;  provided,  however,  that any adjustments which by
               reason of this  subparagraph  J are not required to be made shall
               be carried  forward and taken into  account in making  subsequent
               adjustments.  All  calculations  under the  Paragraph 10 shall be
               made to the  nearest  cent or to the nearest  one-hundredth  of a
               share, as the case may be.

          K.   No  adjustment in the Exercise Rate shall be made for purposes of
               subparagraphs  B and C of this  Paragraph  10 if such  adjustment
               would result in an increase in such Exercise Price or decrease in
               the  Exercise  Rate except that,  in the case of any  Convertible
               Securities in respect of which an adjustment has previously  been
               made  under  subparagraph  B  above  and  which  has  expired  or
               otherwise been canceled without exercise of the rights or options
               evidenced thereby, such previous adjustment shall be reversed.

          L.   Before taking any action which could cause an adjustment pursuant
               to this  Paragraph 10 reducing the Exercise Price per share below
               the then par value (if any) of the  shares  covered  hereby,  the
               Company will take any corporate  action which may be necessary in
               order that the  Company  may  validly  and  legally  issue at the
               Exercise  Price as so  adjusted  shares  that are fully  paid and
               non-assessable.

          M.   The number of shares of capital stock of the Company  outstanding
               at any given time shall not  include  shares  owned or held by or
               for the account of the Company,  and the  disposition of any such
               shares  shall be  considered  an issue or sale of such shares for
               the purposes of this Paragraph 10.

          N.   If any event  occurs as to which  the  other  provisions  of this
               Paragraph  10 are not  strictly  applicable  but the  lack of any
               adjustment  would not fairly  protect the purchase  rights of the
               Holder of this  Warrant in  accordance  with the basic intent and
               principles of such  provisions,  or if strictly  applicable would
               not  fairly  protect  the  purchase  rights of the Holder of this
               Warrant in  accordance  with the basic intent and  principles  of
               such  provisions,  then  the  Company  shall  appoint  a firm  of
               independent  certified public accountants (which shall not be the
               regular auditors of the Company) of recognized national standing,
               which shall give their opinion upon the adjustment,  if any, on a
               basis consistent with the basic intent and principles established
               in the  other  provisions  of this  Paragraph  10,  necessary  to
               preserve, without dilution, the exercise rights of the registered
               Holder of this Warrant. Upon receipt of such opinion, the Company
               shall forthwith make the adjustments described therein. In taking
               any action or making any determination pursuant to the provisions
               of this Section 10, the Company and its Board of Directors shall,
               at all times, exercise reasonable judgment and act in good faith.

          O.   Upon any adjustment of any Exercise  Rate,  then and in each such
               case,  the  Company  shall  promptly  deliver  a  notice  to  the
               registered  Holder of this Warrant,  which notice shall state the
               Exercise Price and Exercise Rate  resulting from such  adjustment
               and the  increase  or  decrease,  if any, in the number of shares
               purchasable at such price upon the exercise hereof, setting forth
               in reasonable detail the method of calculation and the facts upon
               which such calculation is based.

          P.   In the  case  of the  issuance  of  shares  of  Common  Stock  or
               Convertible  Securities for a consideration  in whole or in part,
               other  than  cash,  the  consideration  other  than cash shall be
               deemed  to  be  the  fair  market  value  thereof  as  reasonably
               determined in good faith by the Board of Directors of the Company
               (regardless of accounting treatment thereof);  provided, however,
               that if such  consideration  consists of the cancellation of debt
               issued by the Company the consideration shall be deemed to be the
               amount the  Company  received  upon  issuance of such debt (gross
               proceeds)  plus  accrued  interest  and,  in the case of original
               issue discount or zero coupon indebtedness, accreted value to the
               date of such  cancellation,  but not  including  any  premium  or
               discount  at which the debt may then be  trading  or which  might
               otherwise be appropriate for such class of debt;

          Q.   The  Company  shall  not issue any  shares of its  capital  stock
               (other than Common Stock) at or for  consideration  which is less
               than  fair  value  determined  by the Board of  Directors  of the
               Company in light of all circumstances surrounding such issuance.

     11.  In the case:

          A.   The Company  shall  declare any dividend or  distribution  on its
               Common  Stock (or on any other  shares  which the  Holder of this
               Warrant may become entitled to receive upon exercise hereof); or

          B.   The Company shall authorize the issuance to holders of its Common
               Stock (or on any other  shares  which the Holder of this  Warrant
               may  become  entitled  to  receive  upon  exercise   hereof)  any
               subscription rights or warrants; or

          C.   Of any subdivision,  combination or reclassification of shares of
               Common  Stock of the Company (or any shares of the Company  which
               are subject to this Warrant), or of any proposed consolidation or
               merger  to which the  Company  is to be a party and for which the
               approval of any  shareholders  of the Company is required,  or of
               the proposed sale or transfer of all or substantially  all of the
               assets  of the  Company;  or D.  Of  the  proposed  voluntary  or
               involuntary  dissolution,  liquidation,  or  winding  up  of  the
               Company; or

          E.   The Company  proposes  to effect any  transaction  not  specified
               above which would  require an  adjustment  of the  Exercise  Rate
               pursuant to Paragraph 10 hereof;

          then the Company  shall cause to be mailed to Holders of this Warrant,
          at least ten (10) days  prior to the  applicable  record or other date
          hereinafter   specified,  a  notice  describing  such  transaction  in
          reasonable detail,  specifying the character,  amount and terms of all
          securities  and  the  amounts  of cash  and  other  property,  if any,
          involved in such  transaction and stating (i) the date as of which the
          holders  of Common  Stock (or any such  other  shares) of record to be
          entitled  to  receive  any such  dividend,  distribution,  rights,  or
          warrants  is to be  determined,  or (ii) the  date of  which  any such
          subdivision,  combination,  reclassification,  consolidation,  merger,
          sale,  transfer,  dissolution,   liquidation,  winding  up,  or  other
          transaction is expected to become effective,  and the date as of which
          it is expected that holders of Common Stock (or any such other shares)
          of record  shall be entitled to exchange  the same for  securities  or
          other property, if any, deliverable upon such transaction.

     12.  The Company covenants and agrees that it will not merge or consolidate
          with or into or sell or otherwise transfer all or substantially all of
          its assets to any other corporation or entity unless at the time of or
          prior to such transaction such other corporation or other entity shall
          expressly assume all of the liabilities and obligations of the Company
          under  this  Warrant  and  (without  limiting  the  generality  of the
          foregoing) shall expressly agree that the Holder of this Warrant shall
          thereafter have the right (subject to subsequent  adjustment as nearly
          equivalent as practicable to the adjustments provided for in Paragraph
          10 of this  Warrant) to receive  upon the exercise of this Warrant the
          number and kind of shares of stock and other  securities  and property
          receivable upon such transaction by a Holder of the number and kind of
          shares  which  would have been  receivable  upon the  exercise of this
          Warrant immediately prior to such transactions.

     13.  The Holder of this Warrant Certificate, each transferee hereof and any
          holder and transferee of any Shares, by his acceptance thereof, agrees
          that (i) no public  distribution of Warrants or shares will be made in
          violation of the Act, and (ii) during such period as the delivery of a
          prospectus  with  respect to Warrants or Shares may be required by the
          Act,  no public  distribution  of Warrants or Shares will be made in a
          manner or on terms  different  from  those  set  forth in, or  without
          delivery of, a prospectus then meeting the  requirements of Section 10
          of the Act and in  compliance  with all  applicable  state  securities

     WHEREAS,  the Employment  Agreement was entered into prior to the enactment
of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),

     WHEREAS,  the  compensation  payable to the Employee  under the  Employment

beginning January 1, 1998;

     WHEREAS,  the  Company  proposed,  and  its  shareholders  approved  at the

               paid to other  employees of the Company  aggregating  up to 2% of

          (ii) Any Sales Bonuses  payable to the Employee and Mr.  Calvert under
               Section  3(c)  hereof or the  similar  section  of Mr.  Calvert's
               employment  agreement,  as amended,  shall be deducted before any
               bonuses payable under this Section 3(b) are calculated;

          (iii)Any bonuses  payable to any member of the  Executive  Group under
               this  Section  3(b)  or the  similar  section  of his  employment
               agreement  or  bonuses  paid to other  employees  of the  Company
               aggregating  up to 2% of PTP shall not be deducted  from  pre-tax
               profits  in order to  calculate  the bonus  payable  to any other
               member of the  Executive  Group  under this  Section  3(b) or the
               similar  section  of  such  member's  employment  agreement,   as
               amended;

          (iv) The annual pre-tax profits  calculation  shall be reviewed by the

               of the Executive Group;

          (v)  Any  payments  to the  Employee  by  any  company  that  is not a

               and

          (vi) PTP shall be  determined in accordance  with  generally  accepted
               accounting  principles  and will mean,  subject to the  foregoing
               subparagraphs (i)-(v), the consolidated profits of the Company

          (d) Payment of Bonuses. The Company shall pay Employee the Bonuses due
     hereunder no later than March 15th of the year  following the year in which
     it is earned,  provided,  however,  that before the Company is obligated to

     Compensation  Committee  shall  certify  to the Board of  Directors  of the
     Company that the material terms and  performance  goals hereunder have been
     met, which determination shall be made by the Compensation Committee in its

                         EMPLOYMENT AGREEMENT AMENDMENT


     THIS EMPLOYMENT  AGREEMENT AMENDMENT ( this "Agreement") is between Seitel,
Inc.  (the  "Company"),  a  Delaware  corporation  with its  principal  place of
business in  Houston,  Texas,  and  Herbert M.  Pearlman  (the  "Employee,"  and
collectively  with the  Company,  the  "Parties"),  and is an  amendment to that
certain  Employment  Agreement  between  the  Company  and  the  Employee  dated
effective January 1, 1991 (the "Employment Agreement").

                                    Recitals

     WHEREAS, the Company and the Employee entered into the Employment Agreement
to govern the terms of the Employee's employment by the Company;

     WHEREAS,  the Employment  Agreement was entered into prior to the enactment
of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),
which section limits the  deductibility by corporations of certain  compensation
expenses;

     WHEREAS,  the  compensation  payable to the Employee  under the  Employment
Agreement will become subject to the  restrictions of Section 162(m) of the Code
beginning January 1, 1998;

     WHEREAS,  the  Company  proposed  and  its  shareholders  approved  at  the
Company's annual shareholders' meeting the 1997 Executive Compensation Plan (the
"Plan"),  the  purpose of which was to cause the  compensation  paid to Employee
after January 1, 1998 to comply with the  deductibility  restrictions of Section
162(m) of the Code;

     WHEREAS,  the Employee and the Company are entering into this  Agreement to
amend  the  Employment   Agreement  to  incorporate   therein  the  compensation
provisions approved by the Company's shareholders as set forth in the Plan;

     NOW, THEREFORE, the Parties do hereby agree as follows:

     1. Compensation. Section 3 of the Employment Agreement is hereby amended by
deleting the existing Section 3 and replacing it with the following:

          "3. Compensation:

          (a) Base  Salary.  For services  rendered by the  Employee  under this
     Agreement,  the  Company  shall pay the  Employee  an annual base salary of
     $428,435 in twenty-four (24) bi-monthly installments (the "Base Salary").

          (b) Pre-Tax  Profits Bonus.  Commencing  January 1, 1998, the Employee
     shall  receive  bonus  payments  based on the annual  Pre-Tax  Profits (the
     "PTP") of the Company and its majority owned subsidiaries ("Subsidiaries").
     If the PTP exceeds the PTP Threshold (hereinafter defined),  Employee shall
     receive a pre-tax  profits bonus equal to the difference of (I) 5.0% of PTP
     for PTP up to $50 million and 5.3% of PTP for PTP in excess of $50 million,
     minus (II) $300,000, provided, however, that if the amount determined under
     clause (I) is less than $300,000, no bonus shall be payable hereunder.

          The PTP must equal or exceed ten million dollars  ($10,000,000.00) for
     fiscal  year 1998 and each of the four  years  thereafter,  twelve  million
     dollars  ($12,000,000.00)  for fiscal  year 2003 and each of the four years
     thereafter,  and fourteen million dollars  ($14,000,000.00) for fiscal year
     2008 and  thereafter  (the "PTP  Threshold").  The PTP shall be computed as
     follows:

          (i)  Any bonuses paid to Company employees (other than bonuses paid to
               the Employee, Messrs. Paul A. Frame, Horace A. Calvert, and David
               S. Lawi (collectively, the "Executive Group") and bonuses paid to
               other employees of the Company aggregating up to 2% of PTP) shall
               be deducted before any bonuses payable to the Executive Group are
               calculated;

          (ii) Any Sales  Bonuses  payable to Mr.  Frame and Mr.  Calvert  under
               Section  3(c)  of  their  respective  employment  agreements,  as
               amended,  shall be deducted before any bonuses payable under this
               Section 3(b) are calculated;

          (iii)Any bonuses  payable to any member of the  Executive  Group under
               this  Section  3(b)  or the  similar  section  of his  employment
               agreement  or  bonuses  paid to other  employees  of the  Company
               aggregating  up to 2% of PTP shall not be deducted  from  pre-tax
               profits  in order to  calculate  the bonus  payable  to any other
               member of the  Executive  Group  under this  Section  3(b) or the
               similar  section  of  such  member's  employment  agreement,   as
               amended;

          (iv) The annual pre-tax profits  calculation  shall be reviewed by the
               Company's   outside   auditors  and  approved  by  the  Company's
               Compensation Committee before any bonuses are paid to the members
               of the Executive Group;

          (v)  Any  payments  to the  Employee  by  any  company  that  is not a
               wholly-owned  Subsidiary  of the  Company  but whose  profits are
               included  in the  Company's  pre-tax  profits  calculation  shall
               reduce the Company's  pre-tax profits for purposes of calculating
               any percent of Company  pre-tax  profits payable to the Employee;
               and

          (vi) PTP shall be  determined in accordance  with  generally  accepted
               accounting  principles  and will mean,  subject to the  foregoing
               subparagraphs  (i)-(v),  the consolidated  profits of the Company
               before  payment of all local,  state and federal income taxes but
               after deduction for: (A) all expenses of any subsidiary companies
               or divisions  allocable to such year;  and (B) the payment of any
               management  fee incurred for carrying out the  activities  of the
               Company.

          (c) Payment of Bonus.  The Company  shall pay  Employee  any Bonus due
     hereunder no later than March 15th of the year  following the year in which
     it is earned,  provided,  however,  that before the Company is obligated to
     make  any  payments  of  Bonuses   under   Paragraph   (b),  the  Company's
     Compensation  Committee  shall  certify  to the Board of  Directors  of the
     Company that the material terms and  performance  goals hereunder have been
     met, which determination shall be made by the Compensation Committee in its
     sole discretion.

          (d) Salary Continuation Benefits. The Company will pay, so long as the
     Employee's Employment Agreement, as amended, is in full force and effect on
     the  date  of his  death,  a  monthly  salary  continuation  amount  to the
     Employee's estate or his designee,  for twelve months beginning on the date
     of his  death.  The  annual  salary  continuation  amount  will  equal  the
     Employee's  base salary at his date of death plus an average of the bonuses
     paid to the Employee by the Company for the three calendar years  preceding
     the year of his death."

     2.  Amendment of Employment  Agreement.  This  Agreement is executed as and
shall  constitute  an  amendment  to the  Employment  Agreement,  and  shall  be
construed in connection with and as a part of the Employment  Agreement.  Except
as specifically  amended by this  Agreement,  all of the terms and provisions of
the Employment  Agreement shall remain in full force and effect. In the event of
any conflict between the terms of the Employment Agreement and the terms of this
Agreement, the terms of this Agreement shall apply.

Texas, and, in any action by the Company to enforce this Agreement, venue may be
had in Harris County, Texas.

Agreement,  contains  the  entire  agreement  of  the  Parties.  The  Employment
Agreement and this Agreement may not be changed orally or by action or inaction,
