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 P to the  Company's  Consolidated  Financial  Statements  for financial
information relating to industry segments.

SEISMIC OPERATIONS
- - ------------------
     Since  its  inception  in  1982,  the  Company  has  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 1996, over 300 different  petroleum  companies entered into seismic data
license  agreements  with the Company.  At December 31, 1996,  the Company owned
approximately 880,000 linear miles of 2D and approximately 6,600 square miles of
3D seismic  data which it  maintained  in its library,  constituting  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 17 seismic sales specialists  markets data
from  its  library  and the  creation  of new  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 27 member staff of geotechnical professionals who have in
excess  of  500  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.

     The Company strives to maximize its resales of seismic data,  which require
minimal  incremental cash outlays by the Company and, in turn, can generate both
strong  profits and cash flow. In addition to aggressive  marketing and periodic
data-reprocessing  refinements,  the Company  supplements  its existing  seismic
library by the acquisition of additional data.

     Through its wholly-owned  subsidiary Eagle  Geophysical,  Inc., the Company
conducts  advanced 3D land seismic crew  operations.  The Company operates three
1,850  channel  state-of-the-art  radio-telemetry  systems,  which  the  Company
believes to be among the largest and fastest  real-time systems of their kind in
operation today. These systems,  providing seismic recording capability totaling
5,550 channels,  enable the Company to efficiently  record complex 3D surveys in
the difficult marsh/swamp and transition-zone areas onshore the Gulf Coast where
the Company's data creation activities are concentrated.  Most seismic recording
equipment  use cables to  transmit  data and do not  operate as  efficiently  in
wetland  areas  as  telemetric  systems,   which  use  radio  signals  for  data
transmission.


<PAGE>


     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.

     The Company  conducts  onshore data  creation  activities in three ways. It
performs  multiclient  ("group-shoot")  programs,  under which 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 Company also conducts proprietary creation programs for individual
petroleum  companies,  under which the Company  receives  revenue for creating a
seismic  survey,  the  ownership of which is retained by the  petroleum  company
contracting for the survey.

     Seismic surveys also are conducted for the Company's wholly-owned petroleum
exploration and production subsidiary,  DDD Energy, Inc. ("DDD Energy"). 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. Surveys
conducted for DDD Energy  constitute  intercompany  transactions and the Company
does not record seismic revenue for those  projects.  To date, over 1,100 square
miles of advanced 3D seismic  surveys have been conducted for DDD Energy and its
exploration  partners.  In excess of 425 square  miles of 3D surveys are already
scheduled  to be  conducted  in  1997 by the  Company  for  DDD  Energy  and its
partners,  and over 275 square miles of  additional  surveys are in the planning
stage.

     The Company  contracts with selected  marine  seismic  companies to conduct
offshore 3D seismic data surveys due to the cost inherent in operating  advanced
seismic  vessels.  The Company has a 19% ownership  interest in Energy  Research
International,  a holding  company owning two  marine-seismic  companies,  which
provides the Company with access to offshore  vessels.  The  Company's 3D marine
activities are concentrated on group-shoot  programs in the Gulf of Mexico.  The
Company's wholly-owned  subsidiary,  Seitel International,  Inc., entered into a
50%  joint-venture  agreement  to  conduct  three  high-resolution  2D  surveys,
totaling  approximately 8,455 kilometers (in excess of 5,000 miles) in the Irish
sector of the Atlantic Ocean, designed for exploration  lease-block sales by the
Irish  government  beginning in March 1997.  The  Company's  extensive  in-house
geophysical  team  designs  all of  the  offshore  surveys  and  supervises  the
respective marine contractor utilized to shoot the actual survey.

     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,  state-of-the-art  land seismic recording systems and
crews  specifically to conduct 3D surveys,  a processing  center and proprietary
computer technology coupled with extensive geophysical  application expertise to
effectively  interpret 3D data.  The  Company's  processing  and  interpretation
technology  and  operations  are utilized  exclusively  by DDD Energy to provide
optimum quality control and  confidentiality  for the exploration and production
programs in which DDD Energy participates.

OIL AND GAS EXPLORATION AND PRODUCTION OPERATIONS
- - -------------------------------------------------
     The Company formed DDD Energy,  Inc., a wholly-owned  subsidiary,  in March
1993 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

<PAGE>

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.

     From  inception,  DDD  Energy  has  entered  into and  maintained  cost and
revenue-sharing  relationships  with more than 90  petroleum  companies  and, in
doing  so,  has  received  the  benefit  of  these  petroleum  companies'  land,
geological,   engineering  and  drilling  staffs.  Approximately  350  qualified
exploration and development  prospects have been identified,  located  primarily
onshore Texas and Louisiana, and also onshore Alabama, Mississippi and Arkansas.
DDD Energy's working interest in these prospects ranges from  approximately  10%
to 50%.

     Since inception,  DDD Energy has participated in the drilling of 167 wells,
113 of which are  commercially  productive  for a 68%  success  rate.  Since the
beginning of 1994, the Company has conducted over 1,100 square miles of advanced
3D surveys,  with more than 700 square miles of new surveys currently  scheduled
to be conducted or in the planning stage, for DDD Energy and its partners. These
surveys cover more than 800,000 gross acres,  in which DDD Energy  averages more
than a 25% net working interest.  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.

CUSTOMERS
- - ---------
     During each of 1996,  1995 and 1994,  the Company's  seismic data customers
consisted of more than 300 oil and gas companies.  No one customer accounted for
as much as 10% of the Company's revenues during the years 1996, 1995 or 1994. 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.

COMPETITION
- - -----------
     The  creation  and resale of seismic  data are  highly  competitive  in the
United  States.  There are 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.  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, the technical
proficiency  and  exploration  experience  of its  geotechnical  staff  and  the
state-of-the-art  technology of its seismic  recording  crews.  These  resources
enable  the  Company to provide  high-quality  service  and to create and market
high-grade data.

     In the  exploration  for and  development  of  natural  gas and  crude  oil
reserves,  the Company  believes it can participate  effectively  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  seismic data revenues are  influenced by petroleum  industry
capital  expenditure  budgets  and  spending  patterns.  Those  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
revenues  do not  necessarily  flow  evenly  or  progressively  on a  sequential
quarterly basis during the year. In addition, certain weather-related events may
delay the Company's data creation operations during any given year.

     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 and other factors, which may delay the hookup of successfully
completed  wells  and  delay  the  resultant  production  revenues.  Also,  some
producing  wells may be required  periodically  to go off line  temporarily  for
pipeline maintenance.

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations.

EMPLOYEES
- - ---------
     As of December 31, 1996, the Company and its subsidiaries had 109 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, 84 are related
to the seismic operations and 10 are related to the oil and gas 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 3.  LEGAL PROCEEDINGS
- - --------------------------
     On  May  25,  1995,  Seitel  Geophysical,   Inc.  ("SGI"),  a  wholly-owned
subsidiary of the Company,  filed suit in United States  District  Court for the
Eastern  District  of  Louisiana   against   Greenhill   Petroleum   Corporation
("Greenhill") for breach of contract.  SGI sought to recover  approximately $1.4
million owed by Greenhill to SGI for seismic data acquisition  services provided
to  Greenhill  by SGI in 1994 in  connection  with a 3D  seismic  data  shoot in
southern  Louisiana.  Greenhill  generally denied SGI's allegations and asserted
counter-claims  against SGI.  Prior to SGI bringing the suit against  Greenhill,
Greenhill had already paid SGI in excess of $7 million  under the contract,  and
SGI had provided the seismic data acquired under the contract to Greenhill. This
lawsuit was tried in late May,  1996,  and judgment was entered on June 10, 1996
in favor of SGI for damages of  approximately  $940,000,  including  legal fees,
expenses,  and pre-judgment  interest. The trial court denied all of Greenhill's
counter-claims against SGI. Greenhill is appealing this judgment.  Post-judgment
interest  of  5.62%,  which is based  on the  rate of one  year  Treasury  Bills
immediately  prior to the entry of the judgment,  is accruing on the full amount
of the  judgment.  While the outcome of this  appeal  cannot be  predicted  with
certainty, the Company believes that the trial court's award will be upheld.

</TABLE>

     On March 26, 1997,  the closing  price for the Common Stock was $36.50.  To
the best of the  Company's  knowledge,  there  are  approximately  1,272  record
holders of the Company's Common Stock as of March 26, 1997.

DIVIDEND POLICY
- - ---------------
     The Company did not pay cash dividends  during 1995 or 1996, 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.

     On July 3,  1996,  the  Company  entered  into an  agreement  with  Olivera
Limited,  Dormera  Limited,  and Balmedie Limited  ("Sellers"),  shareholders of
Energy Research International ("ERI"), whereby such Sellers sold an aggregate of
50,000 Ordinary Shares of ERI,  comprising 50% of the outstanding shares of ERI,
to the  Company in  exchange  for the Company  issuing an  aggregate  of 132,075
shares of its Common Stock, par value $0.01 per share ("Company Stock"),  to the
Sellers.  Each Seller  received  one-third  of the Company  stock.  ERI conducts
offshore seismic data acquisition  services through its operating  subsidiaries.
The issuance of the Company stock was made by the Company  without  registration
pursuant  to  Section  4(2) of the  Securities  Act of  1993,  as  amended,  and
Regulation  D  promulgated  thereunder,  as a  transaction  by the  Company  not
involving  any public  offering.  The resale of the Company Stock by the Sellers
was subsequently  registered by the Company on a registration  statement on Form
S-3, declared  effective by the Securities and Exchange  Commission on August 6,
1996.

RESULTS OF OPERATIONS
- - ---------------------
     Total revenue was  $106,002,000,  74,439,000 and  $70,902,000 in 1996, 1995
and 1994,  respectively,  representing increases of 42% from 1995 to 1996 and 5%
from 1994 to 1995.  Revenue  primarily  consists of revenue  generated  from the
seismic business and oil and gas production.

     Seismic revenue was $87,747,000,  $69,598,000 and $69,579,000  during 1996,
1995, and 1994,  respectively.  The increase of  $18,149,000 in seismic  revenue
from  1995 to 1996 is  primarily  attributable  to an  increase  in  demand  for
three-dimensional  seismic  data  resulting  in an increase in licensing of data
from the Company's data library and proprietary data  acquisition  performed for
non-affiliated parties by the Company's crew subsidiary.  The slight increase in
seismic  revenue  between 1995 and 1994  primarily  resulted from an increase in
revenue  generated from the licensing of seismic data currently in the Company's
library,  which was offset by a decrease in revenue  generated from the creation
of new seismic data.  During 1995,  the  Company's  focus was more on generating
revenue from data that had been recently  added to the library (both onshore and
offshore 3D seismic data) than on the creation of new data. The Company believes
the demand for its seismic data  remains  strong due to several  factors:  large
integrated oil and gas companies have reduced  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 $18,255,000, $4,806,000 and $1,204,000 during 1996,
1995 and 1994, respectively.  The increases in oil and gas revenue are primarily
due to  higher production resulting from  more wells being on  line  in 1995 and

<PAGE>


1996 and increased  revenue interest in certain wells. 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 the number of
wells  producing as of December  31, 1994 to increase  from 23 to 68 at December
31, 1995 and to 92 at  December  31,  1996.  Net  production  of oil and gas has
increased  from 54,000  barrels and 268 million cubic feet ("mmcf") for the year
ended  December 31, 1994,  to 193,000  barrels and 1,170 mmcf for the year ended
December  31,  1995,  and to 363,000  barrels  and 4,902 mmcf for the year ended
December 31, 1996.  Additionally,  average oil prices  increased from $12.32 per
barrel in 1994 to $13.85  per  barrel in 1995 and to $18.52  per barrel in 1996.
Average gas prices were $1.76 and $1.55 per mcf in 1994 and 1995,  respectively,
and increased to $2.28 per mcf in 1996.

     Depreciation,  depletion and  amortization  consist  primarily of data bank
amortization.  Data bank amortization  amounted to $30,477,000,  $23,852,000 and
$25,777,000 for the years ended December 31, 1996, 1995 and 1994,  respectively.
As a percentage of revenue from licensing  seismic data, data bank  amortization
was 47%,  45% and 46% for  1996,  1995 and  1994,  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.  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.

     Trends in the Company's (and its industry's)  seismic revenue 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 downturn,  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 is stable and the possibility
for significant improvement exists.

     Cost of sales  consists  of expenses  associated  with the  acquisition  of
seismic data for non-affiliated  parties,  seismic resale support services,  and
oil and gas production.  The increase in cost of sales from  $10,499,000 in 1994
to $13,071,000  in 1995 and to  $19,402,000 in 1996 is due to the  corresponding
increase in revenue from these areas because of their continued growth. Revenues
from these areas  increased  from  $14,033,000 in 1994 to $19,773,000 in 1995 to
$39,534,000 in 1996.  Gross profit margin related to the  acquisition of seismic
data for  non-affiliated  parties was 21%, 22% and 20% for 1996,  1995 and 1994,
respectively.  Gross profit margin  related to oil and gas  production  (revenue
less  production  costs)  was  83%,  67%  and  72%  for  1996,  1995  and  1994,
respectively.

     The Company's selling,  general and administrative  expenses increased from
$14,672,000 in 1994 and $15,393,000 in 1995 to $19,165,000 in 1996. The increase
for each  year was  primarily  a result  of  variable  expenses  related  to the
increased volume of business.  As a percentage of total revenue,  these expenses
were 21% in 1994 and 1995 and decreased to 18% in 1996.  The decrease in 1996 is
primarily due to ongoing cost reduction programs.

     The Company's  interest expense was $3,455,000 in 1994,  $3,407,000 in 1995
and  $4,063,000 in 1996.  The slight  decrease in interest  expense from 1994 to
1995  resulted  from  less  interest   expense  incurred  on  the  Company's  9%
convertible  debentures due to the  conversions and exchanges into common stock,
offset by increased interest expense being incurred primarily on amounts owed to

<PAGE>

a seismic acquisition contractor.  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.

     Interest  income  increased  from  $257,000 in 1994 and $329,000 in 1995 to
$1,163,000 in 1996. The increase in 1996 was primarily  attributable to interest
earned on the investment of increased cash balances.

     On July 3, 1996,  the Company  acquired 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. During
1996,  the Company  recognized  a net loss from its interest in ERI of $186,000,
which excludes  profits earned by ERI on the work performed for the Company.  In
the fourth quarter of 1996, the Company reduced its ownership interest in ERI to
19%.  Since then,  the Company has not  recorded  any portion of ERI's income or
loss  in  the  Company's  consolidated  financial  statements.  This  investment
provides the Company with greater access to offshore  vessels to better meet the
demand for new marine seismic data.

     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.

     In  October  1994,  the  company  called  for  redemption  of  its  12-1/2%
subordinated  debentures due 1999 totaling $3,725,000.  As a result, the Company
recorded  an  extraordinary  charge of  $304,000,  net of a $163,000  income tax
benefit,  associated with the early  extinguishment  of indebtedness,  which has
been reflected as an extraordinary item for the year ended December 31, 1994.

LIQUIDITY AND CAPITAL RESOURCES
- - -------------------------------
     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  used the majority of the proceeds of the Series A and
Series B Notes to repay amounts outstanding under its $25 million revolving line
of credit,  amounts  outstanding  under a wholly-owned  subsidiary's $75 million
reducing revolving line of credit, and amounts owed to a seismic contractor. The
proceeds  of the  Series C Notes  are being  used  primarily  to fund  petroleum
exploration and development  activities of its  wholly-owned  subsidiary and for
other working capital or general corporate purposes.

     The  Company  filed a  registration  statement  on  Form  S-3  (the  "Shelf
Registration  Statement") in June 1994 to 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,  at an aggregate  initial
offering price not to exceed $75,000,000.  The Shelf Registration  Statement was
declared  effective by the Securities and Exchange  Commission on June 30, 1994.
In August 1994, the Company  completed a public offering of 1,061,200  shares of
its common  stock  priced at $32 per share  pursuant  to the Shelf  Registration
Statement. The net proceeds from the offering (after underwriting commission and
offering  expenses) totaled  $31,917,000.  After this sale of common stock at an
initial  aggregate  offering  price  of  $33,958,400,   the  Company  may  offer
additional  securities  in the future for up to an  aggregate  initial  offering
price of $41,041,600 pursuant to the Shelf Registration Statement.

     On July 22, 1996,  the Company  entered  into an  agreement  with The First
National Bank of Chicago for a $25,000,000  unsecured  revolving  line of credit
facility.  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 July 22, 1999. As of March 26, 1997,
the balance  outstanding on the revolving line of credit  amounted to $3,000,000
bearing an interest  rate of 6.125% The Company has received a  commitment  from
its lenders to increase its revolving  line of credit  facility to  $50,000,000,
subject to execution of formal loan documents to evidence this increase.

     On February 6, 1997, a wholly-owned  subsidiary of the Company entered into
a commitment to obtain two term loans aggregating $7,564,000 for the purchase of
a third 3D seismic recording system and other related equipment.  The first loan
will have a principal amount of $558,000,  will be for a term of three years and
will bear interest at the rate of 1.48% above the two year U.S.  treasury yield.
The second loan will have a principal  amount of $7,006,000,  will be for a term
of five years and will bear  interest  at the rate of 1.58% above the three year
U.S. treasury yield. Interim advances totaling $7,564,000 at March 26, 1997 have
been made and bear interest at the rate of LIBOR plus 1.30%.

     On July 9, 1996, a wholly-owned subsidiary of the Company obtained two term
loans  aggregating  $7,264,000  for the  purchase  of land  and  marine  seismic
equipment which secures the debt. The first term loan has a principal  amount of
$5,902,000,  is for a term of five years and bears  interest  at the rate of 8%.
Monthly principal and interest payments total $120,000.  The balance outstanding
on this  loan at March  26,  1997 was  $5,245,000.  The  second  term loan has a
principal amount of $1,362,000,  is for a term of three years and bears interest
at the rate of 8.06%. Monthly principal and interest payments on the second term
loan total $43,000.  The balance  outstanding on this loan at March 26, 1997 was
$1,122,000. The majority of this equipment is under a five year rental agreement
expiring June 30, 2001, whereby the Company receives $138,000 per month.

     From  1993  to  March  1996,  the  Company  and  two  of  its  wholly-owned
subsidiaries  obtained four separate term loans  totaling  $5,449,000,  three of
which  have a three  year term and one which  has a five year  term.  Two of the
loans bear  interest at the rate of 8.413%,  one at the rate of 7.61% and one at
the rate of 7.52%.  The proceeds were used for the purchase of certain  property
and equipment which secures the debt.  Monthly  principal and interest  payments
total approximately  $121,000. The balance outstanding on the loans at March 26,
1997, was $1,980,000.

     In June 1996, a  wholly-owned  subsidiary  of 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  retains  responsibility  for its working  interest share of the cost of
operations. The proceeds of the sale were applied toward the acquisition cost of
certain oil and gas properties.  The Company accounted for the proceeds received
in the transaction as deferred  revenue which will be amortized into revenue and
income as natural gas and other  hydrocarbons  are produced and delivered during
the term of the volumetric production payment agreements.

     During 1994 and 1995,  the Company  entered into three capital leases which
relate to the  purchase  of a 3D seismic  recording  system  and a seismic  data
processing center.  These lease agreements are for terms of three to five years.
Monthly  principal  and interest  payments  total  approximately  $125,000.  The
balance  outstanding  under these capital lease  obligations  was  $2,130,000 at
March 26, 1997.

     During 1996 and 1995,  the Company  received  $11,182,000  and  $6,942,000,
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 1996 and 1995,  the Company also received  $3,204,000  and
$1,900,000,  respectively,  in tax savings.  From January 1, 1997, through March
26,  1997,  the Company  received  $247,000  from the  exercise of common  stock
purchase warrants and options and 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 1996,  gross seismic data bank additions and capitalized oil and gas
exploration  and  development  costs  amounted to $52,143,000  and  $51,361,000,
respectively.  These capital expenditures,  as well as taxes, interest expenses,
cost  of  sales  and  general  and  administrative   expenses,  were  funded  by
operations,  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,  proceeds from the private placement  described above, and
proceeds from the sale of the volumetric  production  payment  described  above.
Acquisitions  of  geophysical  equipment and other  property and equipment  were
funded partially by cash from operations and the remainder through capital lease
financing and term loans.

     Currently,  the Company anticipates capital  expenditures for 1997 to total
approximately $72 million.  Such expenditures include  approximately $46 million
for the creation of proprietary  seismic data, and approximately $26 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,  should  be  sufficient  to fund the 1997
capital  expenditures,  along with  expenditures  for  operating and general and
administrative expenses.  Additionally, the Company could arrange for additional
debt or equity  financing during 1997;  however,  there can be no assurance that
the Company  would be able to  accomplish  any such debt or equity  financing on
terms satisfactory to it.

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, 1996.

                    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, 1996 and 1995, and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended  December 31, 1996.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Seitel,  Inc. and subsidiaries
as of December 31, 1996 and 1995,and the results of their  operations  and their
cash flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

SEITEL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1996

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 cover
onshore and offshore  the U.S.  Gulf Coast  region.  The  Company's  oil and gas
exploration,  development  and production  activities are on properties  located
primarily 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 R, "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. Investment in affiliate was accounted for under the equity method when
the Company  owned 50% of such company and  accounted  for under the cost method
when the  ownership was reduced to 19%. 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, 1996 to be amortized to be 21%,
17%, 12%, 12%, 11%, and 27% for the years ending December 31, 1997,  1998, 1999,
2000, 2001 and 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.

     Net data bank at December 31, 1996 and 1995 was  comprised of the following
(in thousands):

     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, 1996, exploration and development related
overhead costs of  $1,146,000,  $861,000 and $707,000,  respectively,  have been
capitalized to oil and gas properties. For the years ended December 31, 1996 and
1995,  interest  costs of  $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  value,  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  calculated  using  period-end  prices  from
estimated  proved  reserves plus the lower of cost or fair value of  unevaluated
properties, adjusted for the effects of related income taxes.

     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 $445,000,  $(3,000),  and $1,000 for the years ended December 31, 1996,  1995
and  1994,  respectively,  as  such  earnings  are  intended  to be  permanently
reinvested in those 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. Revenue received in advance of
being earned is deferred until earned.

     HEDGING  TRANSACTIONS:  The Company may enter into futures  transactions to
hedge commodity prices associated with the sales of natural gas and crude oil in
order to minimize the risk of market price  fluctuations.  Changes in the market
value of futures  transactions are deferred until the gain or loss is recognized
on the hedged  transactions.  All future contracts permit settlement by delivery
of physical product.

     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.

     EARNINGS PER SHARE:  Earnings  per share is based on the  weighted  average
number of  outstanding  shares of common  stock  during  the  respective  years,
including  common  equivalent  shares  applicable  to assumed  exercise of stock
options and warrants when such common stock  equivalents  are dilutive,  and the
Company's other potentially dilutive securities.

     STOCK-BASED  COMPENSATION:  The Company  accounts for employee  stock-based
compensation   using  the  intrinsic  value  method   prescribed  by  Accounting
Principles Board ("APB") Opinion 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 Statement of  Financial  Accounting  Standards  ("SFAS") No.
123,  "Accounting  for  Stock-Based  Compensation"  on the Company's  results of
operations in 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, 1996 and 1995,  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, 1996 and 1995.
Based  on the  quoted  market  price,  the  fair  value  of  the 9%  convertible
subordinated debentures at December 31, 1995 was $6,962,000.

     IMPAIRMENT OF LONG-LIVED  ASSETS:  In March 1995, the Financial  Accounting
Standards  Board issued SFAS No. 121,  "Accounting  for Impairment of Long-Lived
Assets and for  Long-Lived  Assets to be Disposed Of." This  statement  requires
that long-lived assets be reviewed for impairment  whenever events or changes in
circumstances  indicate  that  the  carrying  value  of  an  asset  may  not  be
realizable.  The Company  adopted SFAS No. 121  effective  January 1, 1996;  the
adoption  of this  statement  did not have a  material  effect on the  Company's
consolidated financial statements.

NOTE B--INCOME TAXES

     The  discussion  of income  taxes  herein  does not  include the income tax
effects of the discontinued  operations or the  extraordinary  item explained in

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%. No amounts were  outstanding  under this

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 retains
responsibility  for its working  interest  share of the cost of  operations.  At
December 31, 1996,  there were  approximately  5.5 billion cubic feet of gas and
279,000  barrels  of other  hydrocarbons  remaining  to be  delivered  under the
agreements.

     The Company  accounted  for the  proceeds  received in the  transaction  as
deferred revenue which is being amortized into revenue and income as natural gas
and  other  hydrocarbons  are  produced  and  delivered  during  the term of the
volumetric  production  payment  agreements.  Annual  remaining  amortization of
deferred revenue under the volumetric production payment agreements, at December
31, 1996 is estimated as follows (in thousands):

NOTE F--CONTINGENCIES AND COMMITMENTS

     At December 31, 1996 and 1995,  $274,000  and  $279,000,  respectively,  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 September 30, 1996, a  wholly-owned  subsidiary  of the Company  entered
into an  agreement  for the  purchase of a telemetry  seismic  data  acquisition
system at a cost of approximately $3,500,000.  Payment was made upon delivery of
the system in January 1997.

     On July 21, 1992, the Company's  Board of Directors  approved  payment of a
one-time  $2,500,000 bonus to be divided among five key employees upon the event
of the market price of the  Company's  stock  maintaining  or exceeding  $20 per
share for at least 90  consecutive  days (the "Target Date" ) at any time before
July 21,  1997.  The Target  Date was  achieved  in June 1994.  The bonus  vests
equally  over  the 12  quarters  following  the  Target  Date,  contingent  upon
continued  full-time  employment,  except in the event of death or disability in
which case the  balance of the bonus will be due and  payable  immediately.  The
bonus expense is being  recognized over the vesting period.  For the years ended
December 31, 1996, 1995 and 1994, $833,000, $833,000 and $625,000, respectively,
was charged to expense for this bonus. As of December 31, 1996, $209,000 remains
to be charged to  expense.  Interest,  at the  prevailing  prime  rate,  is paid
quarterly on the total outstanding bonus.

     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 $60 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,  1997,  the market price of the  Company's
common stock was $36.50 share.

     The  Company  applies  APB  Opinion  25  and  related   interpretations  in
accounting  for its  stock-based  compensation  plans.  APB  Opinion 25 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):

</TABLE>

     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
1996 and 1995,  respectively:  risk-free  interest  rates  ranging from 5.91% to
7.03% and 5.54% to 7.02%;  dividend  yield of 0% and 0%; stock price  volatility
ranging from 46.49% to 62.62% and 47.18% to 65.06%;  and  expected  option lives
ranging from 5 to 10 years and 2.8 to 10 years. The weighted-average  fair value
of options  granted  during  1996  and  1995  was $22.40  and $19.32 per option,

                                      F-15


<PAGE>
respectively, for options granted at fair market value and $18.86 per option for
options  granted  above fair market value in 1995.  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, 1996,  30,000 shares have been reserved for issuance
under this plan and  directors  have  accumulated  687 deferred  shares in their
accounts  which will not be  distributed  until such time as  designated  by the
director.

NOTE H--COMMON STOCK

     The  Company  filed a  registration  statement  on  Form  S-3  (the  "Shelf
Registration  Statement") in June 1994 to 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,  at an aggregate  initial
offering price not to exceed $75,000,000.  The Shelf Registration  Statement was
declared  effective by the Securities and Exchange  Commission on June 30, 1994.
In August 1994, the Company  completed a public offering of 1,061,200  shares of
its common  stock  priced at $32 per share  pursuant  to the Shelf  Registration
Statement. The net proceeds from the offering (after underwriting commission and
offering  expenses) totaled  $31,917,000.  After this sale of common stock at an
initial  aggregate  offering  price  of  $33,958,400,   the  Company  may  offer
additional  securities  in the future for up to an  aggregate  initial  offering
price of $41,041,600 pursuant to the Shelf Registration Statement.

     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 $5.375 per share. The Company recorded related compensation
expense of $48,000,  $56,000 and $64,000 for the years ended  December 31, 1996,
1995 and 1994,  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 1996, 1995
and 1994, the Company received $190,000, $156,000 and $488,000, 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, 1996, no preferred stock had been issued.

NOTE J--RELATED PARTY TRANSACTIONS

     The Company owed Helm  Resources,  Inc. and its  subsidiaries  ("Helm"),  a
company  that has three  executive  officers  who are  directors of the Company,
$23,000 and $51,000 as of December 31, 1996 and 1995, 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  $80,000,
$78,000 and $84,000 for these general and  administrative  expenses during 1996,
1995 and 1994, respectively. Management believes that these expenses, which were
specifically  related to the Company's  business,  represented costs which would
have been  incurred in the same amount 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  1996,  1995 and  1994  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 3% of the total
investment  made by such  partnership  and DDD Energy,  Inc. 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 arms length.

NOTE K--MAJOR CUSTOMERS

     No customers  accounted for 10% or more of revenues  during the years 1996,
1995 or 1994.

     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 L--PROFIT-SHARING PLAN

     The Company has an Incentive  Compensation  Agreement for certain employees
under which annual contributions,  ranging from 2.5% to 5% of revenues generated
on certain seismic programs,  are required.  Contributions amounted to $550,000,
$263,000 and $652,000, for 1996, 1995 and 1994, respectively.

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, $1,196,000, and
$52,000  for the three  years  ended  December  31,  1996,  net of an income tax
benefit of $580,000  for 1996,  $703,000  for 1995,  and  $30,000  for 1994.  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.  No additional loss on disposal of discontinued
operations was incurred during 1996.

     Revenue from the discontinued operations was $13,116,000 and $2,864,000 for
the years ended December 31, 1995 and 1994, respectively. The net liabilities of
discontinued  operations at December 31, 1995,  consisted  primarily of accounts
payable  and  accrued  liabilities  offset by trade  receivables  and income tax
benefits.  No assets or  liabilities  relating  to the  discontinued  operations
remained at December 31, 1996.

NOTE N--EARLY EXTINGUISHMENT OF DEBT

     In  October  1994,  the  Company  called  for  redemption  of  its  12-1/2%
subordinated  debentures  due 1999  totaling  $3,725,000,  which  was  funded by
proceeds  from the public  offering of common  stock in 1994.  As a result,  the
Company  recorded a charge of  $304,000,  net of a $163,000  income tax benefit,
associated  with  the  early  extinguishment  of  indebtedness,  which  has been
reflected  in  the  Company's   consolidated   statement  of  operations  as  an
extraordinary  item for the year ended December 31, 1994.  This charge  includes
the write-off of unamortized bond discount totaling $176,000.

NOTE O--STATEMENT OF CASH FLOW INFORMATION

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

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

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

     1.   During 1996,  1995 and 1994, the Company issued  214,304,  165,296 and
          1,006,667,   respectively,   shares  of  its  common  stock  upon  the
          conversion  and exchange of  $1,989,000,  $1,534,000  and  $9,342,000,
          respectively,  of  its  9%  convertible  subordinated  debentures.  In
          connection  with these  conversions  and exchanges,  unamortized  bond
          issue costs totaling $109,000,  $98,000 and $626,000 during 1996, 1995
          and  1994,  respectively,  have been  charged  to  additional  paid-in
          capital.

     2.   During 1996,  the Company issued 132,075 shares of its common stock in
          exchange for a 50% equity interest in a marine seismic company.

     3.   During 1996, the Company  redeemed a portion of its equity interest in
          a marine seismic company in exchange for a note totaling $2,680,000.

     4.   During 1995 and 1994,  the  Company  licensed  seismic  data valued at
          $1,534,000 and $3,162,000,  respectively, in exchange for the purchase
          of property and equipment and seismic data for its library.

     5.   During  1996,  1995  and  1994,  capital  lease  obligations  totaling
          $41,000, $10,000 and $5,639,000,  respectively, were incurred when the
          Company entered into leases for property and equipment.

     6.   During 1995, the Company  acquired  $330,000 of property and equipment
          by incurring a directly related term loan.

NOTE R--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 Company has also presented, as additional information,  proved reserves
including   quantities   dedicated  to  future  deliveries  required  under  the
volumetric  production  payment.  The Company  believes that this information is
informative  to readers of its  financial  statements as the related oil and gas
properties  costs and  deferred  revenue are included in the  Company's  balance
sheet for 1996. This  additional  information is not required to be presented in
accordance  with SFAS No. 69;  however,  the Company  believes  this  additional
information  is useful in  assessing  its  reserve and  financial  position on a
comprehensive basis.

     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. at December
31,  1996,  and by Forrest A. Garb &  Associates,  Inc. at December 31, 1995 and
1994. 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,  base
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.

     The presentation of the standardized  measure of discounted future net cash
flows and  changes  therein  excludes,  for 1996,  amounts  dedicated  to future
deliveries required under a volumetric  production payment. The Company has also
presented,  as additional  information,  the standardized  measure of discounted
future net cash flows and changes therein  including amounts dedicated to future
deliveries  required  under  the  volumetric  production  payment.  The  Company
believes  that this  information  is  informative  to readers  of its  financial
statements because the related oil and gas properties costs and deferred revenue
are shown in the Company's  balance sheet for 1996. This additional  information
is not required to be presented in  accordance  with SFAS No. 69;  however,  the
Company believes this additional  information is useful in assessing its reserve

hereby deleted and replaced with the following:

Limited Transferability of Options

        The Committee may, in its discretion,  authorize all or a portion of the
Options  granted to an  optionee to be on terms  which  permit  transfer by such
optionee  to  (1)  the  spouse,   children  or  grandchildren  of  the  optionee
("Immediate Family Members"), (2) a trust or trusts for the exclusive benefit of
such Immediate Family Members,  (3) a partnership in which such Immediate Family
Members are the only  partners,  or (4) such other person or persons in the sole
discretion  of the  Committee,  provided that the Option  Agreement  pursuant to
which such  Options are granted  must be  approved  by the  Committee,  and must
expressly  provide  for   transferability  in  a  manner  consistent  with  this
paragraph,  and provided  further,  that  subsequent  transfers  of  transferred
Options shall be prohibited  except those by will or in accordance with the laws
of descent and distribution. Following transfer, any such Options shall continue
to be subject to the same terms and  conditions as were  applicable  immediately
prior to transfer,  provided that for purposes of this Plan the transferee shall
be  treated  as  optionee.  However,  the events of  termination  of  employment
described in this Plan and in the applicable Option Agreement,  as well as other
similar conditions  relating to  exercisability,  termination,  expiration,  and
vesting shall continue to be applied with respect to the original optionee,  and
following  discontinuance  of employment of such original optionee or such other
event,  the Options shall be exercisable  by the transferee  only to the extent,
and for the periods specified  pursuant to the terms of this Plan and the Option
Agreement.  If the Committee does not so authorize  Options to be  transferable,
such  Options  shall not be  transferable  other  than by will or by the laws of
descent  and  distribution,   and  during  a  Participant's  lifetime  shall  be
exercisable only by him (unless he becomes disabled,  in which event they may be
exercised by his legal representative).

       Amendment to Seitel, Inc. Non-Employee Directors' Stock Option Plan
                           Effective December 31, 1996

Section 9(c) of the Plan is hereby deleted and replaced with the following:

(c) Limited Transferability. The Options granted hereunder may be transferred by
a Participant to (1) the spouse,  children or  grandchildren  of the Participant
("Immediate Family Members"), (2) a trust or trusts for the exclusive benefit of
such Immediate Family Members,  (3) a partnership in which such Immediate Family
Members  are the only  partners,  or (4) such other  person or persons as may be
approved  by the Board of  Directors  in their sole  discretion,  provided  that
subsequent  transfers of transferred Options shall be prohibited except those by
will or in  accordance  with the laws of  descent  and  distribution.  Following
transfer,  any such Options  shall  continue to be subject to the same terms and
conditions as were applicable  immediately prior to transfer,  provided that for
purposes of this Plan the transferee shall be treated as optionee.  However, the
events of  termination  of  employment  described in this Plan, as well as other
similar conditions  relating to  exercisability,  termination,  expiration,  and
vesting shall continue to be applied with respect to the original optionee,  and

event,  the Options shall be exercisable  by the transferee  only to the extent,
and for the periods specified pursuant to the terms of this Plan.

                           Effective December 31, 1996



The  sixth  paragraph  of the  Plan is  hereby  deleted  and  replaced  with the
following:

         The Board of  Directors  may,  in its  discretion,  authorize  all or a
portion of the Warrants  granted  pursuant to this Plan be on terms which permit
transfer by the  Warrantholder  to (1) the spouse,  children or grandchildren of
such Warrantholder  ("Immediate Family Members"),  (2) a trust or trusts for the
exclusive  benefit of such Immediate Family Members,  (3) a partnership in which
such Immediate Family Members are the only partners, or (4) such other person or
persons in the sole  discretion  of the Board of  Directors,  provided  that the
Warrant Certificate pursuant to which such Warrants are granted must be approved
by the Board of Directors,  and must expressly provide for  transferability in a
manner  consistent with this paragraph,  and provided  further,  that subsequent
transfers of transferred Warrants shall be prohibited except those by will or in
accordance with the laws of descent and distribution.  Following  transfer,  any
such Warrants  shall  continue to be subject to the same terms and conditions as
were  applicable  immediately  prior to transfer,  provided that for purposes of
this Plan the transferee  shall be treated as the  Warrantholder.  However,  the
events of termination of employment described in this Plan and in the applicable
Warrant   Certificate,   as  well  as  other  similar  conditions   relating  to
exercisability,  termination,  expiration,  and  vesting  shall  continue  to be
applied with respect to the original Warrantholder, and following discontinuance
of employment of such original  Warrantholder  or such other event, the Warrants
shall be exercisable by the transferee  only to the extent,  and for the periods
specified pursuant to the terms of this Plan and the Warrant Certificate. If the
Board of  Directors  does  not so  authorize  Warrants  issued  hereunder  to be
transferable,  such Warrants shall not be transferable  other than by will or by
the laws of descent  and  distribution,  and during a  Warrantholder's  lifetime
shall be  exercisable  only by him (unless he becomes  disabled,  in which event
they may be exercised by his legal representative).

     the covenants and make the representations and warranties set forth in this
     Agreement.

NOW, THEREFORE, The parties agree as follows:

1.   Assignment and Assumption.
     Assignor hereby sells,  assigns,  transfers and sets over unto Assignee and
     unto Assignee's  successors and assigns,  all right, title, and interest of
     Assignor  under,  in and to the Lease.  The Assignee  hereby  assumes,  and
     covenants with Assignor and MetLife to perform fully, all the duties of the
     Assignor  under the Lease.  It is  expressly  understood  and  agreed  that
     Assignee assumes all such obligations notwithstanding the fact that some of
     such obligations may have accrued prior to the date hereof.

2.   Representations  and  Warranties  of Assignee  and  Assignor.  Assignee and
     Assignor represent and warrant individually and respectively as applicable,
     to MetLife as follows:  

     a.   The Assignee is a corporation  duly organized and validly  existing in
          good  standing  under  the laws of the State of  Delaware  and has the
          power and  authority to enter into and perform its  obligations  under
          this  Agreement.  The  execution,  delivery  and  performance  of this
          Agreement has been duly authorized by all necessary action on the part
          of the Assignee  and the  Assignor,  does not require any  stockholder
          approval,  or approval  or consent of any general or limited  partner,
          trustee or holders of any  indebtedness or obligations of the Assignee
          or Assignor  except such as have been duly  obtained  and does not and
          will not contravene any law, judgment,  governmental rule,  regulation
          or order  applicable  to or binding on the Assignee or Assignor or any
          of their  subsidiaries or the  certificates of incorporation or bylaws
          of the Assignee or Assignor or any of their subsidiaries or contravene
          the  provisions  of, or constitute a default  under,  or result in the
          creation of any lien (other  than as  permitted  under the Lease) upon
          the  property  of  the  Assignee  or  Assignor  under  any  indenture,
          mortgage, chattel mortgage, deed of trust, conditional sales contract,
          bank loan or agreement or  instrument,  or other contract or agreement
          to which the Assignee or Assignor or any of their  subsidiaries  are a
          party or by which  they or any of their  subsidiaries  may be bound or
          affected;

     b.   This agreement  constitutes the legal, valid and binding obligation of
          the  Assignee  and  Assignor   enforceable  against  said  parties  in
          accordance with its terms;

     c.   Except  for the  filings  and  recordings  consummated  at the time of
          execution of the Lease and except for the filing and recording of this
          Agreement, no further action, including any filing or recording of any
          document,  is necessary or advisable in order to establish and protect
          MetLife's  title to and  interest  in the  Equipment  as  against  the
          Assignee,  the  Assignor,  and any  third  parties  in any  applicable
          jurisdictions in the United States.

3.   Assignors Continuing Obligation and Guaranty.
     Assignor covenants with MetLife that  notwithstanding its assignment of the
     Lease to the  Assignee,  Assignor  will  duly and  punctually  perform  and
     observe each and every obligation, covenant,  representation,  warranty and
     agreement to be performed  and observed by the Lessee under the  provisions
     of the Lease, notwithstanding the fact that Assignee is similarly obligated
     by the terms of this  Agreement  to perform or observe  those  obligations,
     covenants,  representations or warranties of Lessee arising pursuant to the
     terms  of the  Lease;  provided,  however,  that  Assignor  shall  have  no
     obligation  hereunder to make any payment to MetLife  required by any Lease
     provision to the extent that Assignee has satisfied the  obligations of the
     Lessee arising  pursuant to such Lease  provision.  Except as expressly set
     forth in the  preceding  sentence,  Assignor is not released in any respect
     from its  obligations  to  MetLife  arising  under  the  Lease  or  related
     documents.  The Assignor hereby  acknowledges and consents that MetLife may
     agree with the  Assignee to extend the time for making  payments for any or
     all of the  amounts  due or to become  due  under  the Lease and  documents
     executed  in  conjunction  therewith  or that the  Lease and  documents  in
     conjunction  therewith  may be  changed in any manner at the option of said
     Assignee and without Assignor's  consent and that Assignor's  obligation to
     perform in accordance with this Paragraph 3 shall extend to such agreements
     as  changed  in the same  manner  as if such  changes  had been part of the
     agreements as originally executed and delivered.

     The Assignor hereby  absolutely and  unconditionally  guarantees to MetLife
     the  full  and  timely  performance  by the  Assignee  of  all  obligations
     whatsoever  which  the  Assignee  has  incurred  or is under  or which  the
     Assignee  may at any time  incur or be under to MetLife  pursuant  to or in
     connection with any of the transactions  contemplated by the Lease and this
     Agreement; including but not limited to all obligations of the Assignee for
     the payment of money  whether by reason of covenant,  indemnity,  breach of
     warranty or otherwise. MetLife shall not be bound to exhaust their recourse
     nor to take any other action  against the  Assignee or other  parties or on
     any  collateral  they may hold  before  being  entitled  to  payment by the
     Assignor of all amounts hereby guaranteed. The Assignor specifically agrees
     that it  shall  not be  necessary  or  required  in order  to  enforce  the
     obligations  of the  Assignor  hereunder  that there be,  and  specifically
     waives:  notice of performance or  nonperformance  of the Lease;  demand of
     payment from the  Assignee;  presentment  for payment upon  Assignee or the
     making of any  protest;  notice of the  amount  of  guaranteed  obligations
     outstanding at any time;  notice of nonpayment or failure to perform on the
     part of the Assignee;  and any other  circumstances  which might  otherwise
     constitute a legal or equitable defense or discharge of a Guarantor.

4.   Financial Data.
     During the term of this  Agreement,  Assignee  will  furnish to MetLife and
     will cause any guarantor of Assignee's obligations to furnish to MetLife on
     request (i) annual balance sheet and profit and loss statements prepared in
     accordance  with  generally  accepted  accounting  principles and practices
     consistently applied and, if MetLife so requires, accompanied by the annual
     audit  report of an  independent  certified  public  accountant  reasonably
     acceptable to MetLife, and (ii) all other financial information and reports
     that  MetLife  may from  time to time  reasonably  request,  including,  if
     MetLife so requires,  income tax returns of Assignee  and any  guarantor of
     Assignee's obligations hereunder.

     Assignee shall, from time to time,  furnish all such information as MetLife
     may  reasonably  request  concerning  Assignee  and its  affairs  and shall
     execute and  deliver  such  documents  and perform all such other acts that
     MetLife  may  reasonably  request  in order to carry  out any  transactions
     contemplated by this Agreement.

5.   Miscellaneous.
     This Agreement may not be amended  without the express  written  consent of
     MetLife. This Agreement supersedes all prior agreements between the parties
     relating to the  assignment  from  Assignor  to Assignee of the  Assignor's
     interest in the Lease or the Equipment.

6.   Counterparts.
     This Agreement may be signed in any number of counterparts required for the
     convenience of the parties, all of which when taken together shall form one
     and the same Agreement.

IN WITNESS  WHEREOF,  the parties  hereto have executed this Agreement as of the
day and year first above written.

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

   SECTION 3.1 Debtor's Representations and Warranties.

   Debtor hereby represents and warrants to Secured Party that:

      (a) Debtor is a corporation  duly organized and validly existing under the
   laws  of the  State  of  Delaware  and  has all  requisite  corporate  power,
   authority and legal right to own its properties, including without limitation
   the  Collateral,  to conduct its  business as is now being  conducted  and to
   execute, deliver and perform its obligations under the Notes, this Agreement,
   each other Security Instrument to which it is a party and each other document
   or  agreement  related to the  Collateral  to which it is a party.  Debtor is
   fully  qualified to do business and is in good standing in each  jurisdiction
   in which the  failure to be in good  standing  would have a material  adverse
   effect on the business or operations of Debtor.

      (b) The execution,  delivery and performance by Debtor of the Notes,  this
   Agreement  and each  other  Security  Instrument  to which it is a party  are
   within Debtor's corporate powers,  have been duly authorized by all requisite
   corporate action,  do not contravene  Debtor's charter or by-laws or any law,
   governmental  rule or regulation,  or any order,  writ,  injunction,  decree,
   determination or award currently in effect  applicable to, or any contractual
   restriction  binding  on or  affecting,  Debtor  or any  of  its  properties,
   including without limitation the Collateral,  and do not result in or require
   the creation of any Lien, security interest, right of acceleration, charge or
   encumbrance  (other than pursuant to this  Agreement) upon or with respect to
   any of its properties.

      (c) No  authorization  or approval or other action by, and no notice to or
   filing (other than the filings  referred to in subparagraph  (f) below) with,
   any  governmental  authority or regulatory  body,  shareholders  or any other
   Person is required for the due execution,  delivery and performance by Debtor
   of this Agreement or any other Security Instrument to which it is a party.

      (d) The Notes, this Agreement and each other Security  Instrument to which
   Debtor is a party are the legal,  valid and  binding  obligations  of Debtor,
   enforceable  against  Debtor  in  accordance  with  their  respective  terms,
   subject, in the case of enforceability, to applicable bankruptcy, insolvency,
   reorganization,   moratorium  and  other  laws  affecting  creditors'  rights
   generally and to the application of general  principles of equity (regardless
   of whether such  enforceability is considered in a proceeding in equity or at
   law).

      (e) The proceeds of the Loans will be used only to finance the purchase by
   Debtor  of the  Equipment;  Debtor  owns  good  and  marketable  title to the

   Permitted  Encumbrances in favor of Secured  Party);  and the Equipment is in
   good condition and ready for operation.  The Equipment is and will retain its
   character  as  personal  property,  and  neither  Debtor,  Guarantor,  or any
   Affiliate or Subsidiary  of either Debtor or Guarantor  shall affix or attach
   any item of  Equipment  in any  manner  so as to alter the  character  of the
   Equipment as personal property subject to the UCC.

      (f) Except for the notation on the  certificates  of title naming  Secured
   Party as first  lienholder with respect to all items of Equipment  subject to
   motor vehicle titling and registration laws, the filing of Uniform Commercial
   Code  financing  statements  in the office of the  Secretary  of State of the
   State of Texas will create a valid perfected first priority security interest
   in the Collateral,  securing the payment of the Secured Obligations,  and all
   filings and other actions  necessary or desirable to perfect and protect such
   security  interests will have been taken.  No Person other than Secured Party
   holds any security interest  affecting the Collateral.  No effective Security
   Instrument or other instrument  similar in effect covering all or any part of
   the  Collateral is on file in any recording  office,  except such as may have
   been filed in favor of Secured Party relating to this Agreement.

   in  Guarantor's  financial  condition  since  the  date of the  most  current
   financial statement delivered to Secured Party.

      (k) There is no pending, or to the Debtor's knowledge,  threatened, action
   or Proceeding  affecting Debtor,  Guarantor or any of their properties before
   any  court,  governmental  agency  or  arbitrator  which may  materially  and
   adversely  affect the  condition  (financial  or  otherwise) or operations of
   Debtor,  Guarantor or any of their properties or which purports to affect the
   validity or enforceability of the Notes, this Agreement or any other Security
   Instrument to which Debtor is a party.

      (l) No Default or Event of Default has occurred and is continuing.

      (m) All sales,  transfer,  use,  documentation  or similar taxes,  fees or

   paid to the extent such are in  connection  with the sale to and  purchase by
   Debtor of the Equipment.

      (n)  Debtor is not a party to, nor bound by, any  contract,  agreement  or

      (q) Debtor has not incurred any accumulated unfunded deficiency within the
   meaning of the Employee  Retirement  Income  Security Act of 1974, as amended
   from time to time ("ERISA") nor has Debtor incurred any material liability to
   the Pension Benefit Guaranty  Corporation ("PBGC") established under such Act
   (or any successor thereto under such Act) in connection with any Plan. Debtor
   and its  Affiliates  are in  compliance  in all material  respects with those
   provisions of ERISA and the regulations and public interpretations thereunder
   which  are  applicable  to  Debtor  and  its  Affiliates,   except  for  such
   noncompliance  as would not have a material  adverse  effect on the financial
   condition of Debtor and its Affiliates, taken as a whole.

      (r) Debtor has filed all income tax returns  required to be filed prior to
   the  date  hereof  with  the  various  governmental  entities  having  taxing

               INSURANCE, TRANSFER, CONDEMNATION AND EVENT OF LOSS

   SECTION 4.1 Insurance.

   (a) Property and Liability Insurance. So long as this Agreement is in effect,
Debtor shall  maintain and keep in force,  or cause to be maintained and kept in
force,  without cost or expense to Secured  Party,  with respect to all items of
Equipment  prior to the expiration or earlier  termination of this Agreement (i)
all-risk  property  damage  insurance  in an amount not less than the  aggregate
Termination  Value  for all  items  of  Equipment  of  such  type  as  shall  be
satisfactory to Secured Party and (ii) commercial  general liability  insurance,
including blanket contractual and personal injury insurance,  covering any risks
which  Secured  Party or Debtor might incur by reason of the use or operation of
the  Equipment in or over any area,  in an amount not less than  $6,000,000  per
occurrence. Such insurance policy or policies referenced to in clause (i) of the
preceding  sentence will name Secured Party as a loss payee to the extent of its
interest;  provided,  that upon  verification  by Secured Party that all amounts
owing to Secured  Party  under the  Agreement,  the Notes or any other  Security
Instrument  have been paid in full, then Secured Party shall remit all remaining
property damage  insurance  proceeds,  respecting any item of Equipment,  to the
extent such proceeds are controlled by Secured Party, to Debtor.  Such insurance
policy or policies  referenced to in clause (ii) of the preceding  sentence will
name Secured Party as an additional  insured.  Each of the policies  required by
this Section 4.1 will provide that (A) the same may not be  invalidated  against
Secured  Party by  reason  of (1) any  violation  of a  condition  or  breach of
warranty of the  policies or the  application  therefor by any Person  excepting
Secured  Party,  (2) the use of any item of Equipment for purposes not permitted
by such policies by any Person  excepting  Secured  Party,  (3) any  foreclosure
proceeding or notice of sale regarding any item of Equipment or (4) the title or
beneficial  ownership of any item of Equipment  being held by a party other than
Debtor;  (B) the policies may be canceled or  materially  amended by the insurer
only after  thirty (30) days' prior  written  notice to Secured  Party;  (C) the
interests of Secured Party in such  insurance  policies  (except with respect to
commercial  general  liability) are  assignable and (D) such insurance  policies
shall be primary  insurance.  Each of the policies  required by this Section 4.1
shall  otherwise be reasonably  satisfactory  to Secured Party.  The policies of
insurance  required under this Section shall be valid and  enforceable  policies
issued by insurers of recognized  responsibility acceptable to Secured Party. On
or before the date hereof,  and  thereafter at intervals of not more than twelve
months,  Debtor  will  furnish  or  cause to be  furnished  to  Secured  Party a
certificate  or other  evidence  satisfactory  to  Secured  Party  signed  by an
independent  insurance broker  certifying to Secured Party's  satisfaction  that
Debtor has  insurance  in place with  respect  to all items of  Equipment  which
complies with the insurance requirements of this Agreement. If Debtor shall fail
to cause the  insurance  required  under  this  Section  4.1 to be  carried  and
maintained,  Secured  Party may, but shall have no obligation  to,  provide such
insurance  and Debtor  shall  reimburse  Secured  Party upon demand for the cost
thereof as a supplemental  payment  hereunder in addition to other amounts owing
with respect to the Notes or this Agreement.

   SECTION 4.2 Transfer of Collateral.

   Except as otherwise  expressly  provided by the provisions of this Agreement,
Debtor will not (prior to the satisfaction of all Obligations)  lease,  Grant or
otherwise transfer the Collateral or any part thereof or any interest therein to
any party other than Secured Party without Secured Party's prior written consent
and any and all such  transfers  shall be made  under  and  subject  to  Secured
Party's   security   interest  in  such  Collateral   hereunder.   Prior  to  or
simultaneously with any such transfer, the transferee shall accept, agree to and
execute an agreement assuming Debtor's Obligations to Secured Party, in form and
substance satisfactory to Secured Party.

   SECTION 4.3 Condemnation.

   Immediately  upon obtaining  knowledge  thereof,  Debtor shall notify Secured
Party of any  condemnation or other eminent domain  Proceedings  with respect to
any item of Equipment.  Secured Party may  participate in any such  Proceedings,
and Debtor shall provide  Secured Party with all  instruments  required by it to
permit such participation upon obtaining actual knowledge thereof.  Debtor shall
pay all  reasonable  fees and expenses  incurred by Secured  Party in connection
with Secured Party's participation in any such Proceedings. All proceeds arising
from any such  eminent  domain  Proceedings  shall be paid to and applied by the
Secured Party as specified in Section 5.3 hereof.

   SECTION 4.4 Certain Events of Loss.

   Upon  the  occurrence  of an  Event  of  Loss  with  respect  to any  item of
Equipment,  Debtor shall pay Secured Party within thirty (30) days after receipt
of  insurance  proceeds  after the  occurrence  of such Event of Loss (but in no
event shall such period  extend 120 days  beyond the date of the  occurrence  of
such Event of Loss) or, if such day is not a Business Day, on the next occurring
Business  Day (the "Event of Loss  Payment  Date") an amount equal to the sum of
(a)  the  Termination  Value  (computed  as  of  the  Installment  Payment  Date
immediately preceding the Event of Loss Payment Date) for the items of Equipment
then  subject to the Event of Loss,  plus (b) all accrued  but unpaid  interest,
plus (c) any  Break-Funding  Costs with respect to the items of  Equipment  then
subject to the Event of Loss, plus (d) all other  obligations owing hereunder on
the Event of Loss Payment Date. Upon payment of the amounts set forth in (a)-(d)
above,  Secured  Party  shall  release its Lien on the items of  Equipment  then
subject to the Event of Loss.

      kind, all of which are hereby expressly waived by Debtor;

         (ii)  exercise,  in respect of the  Collateral,  in  addition  to other
      rights and remedies provided for herein or otherwise  available to it, all
      the rights and remedies of a secured party on default under the UCC and/or
      other  applicable  law and also (A) require  Debtor to, and Debtor  hereby

      by Secured Party and (B) without  notice except as specified  below,  sell

      Debtor of the time and place of any public  sale or the time  after  which
      any private sale is to be made shall constitute  reasonable  notification.
      Secured  Party  shall  not be  obligated  to make any  sale of  Collateral

      and  remedies of Secured  Party  hereunder,  or under or in respect of any
      other Security Instrument, or otherwise.

   portion of the Collateral pursuant to subsection (a)(ii) of this Section 5.2.
   All earnings,  revenues,  proceeds, rents, issues, profits and income derived
   pursuant to subsection (a)(iv) of this Section 5.2 (after deducting costs and
   expenses of  operation  and other proper  charges),  all proceeds of any such
   sale and all other money and  property  received or  recovered by the Secured
   Party  pursuant to this Section 5.2 shall be held and applied as set forth in
   Section 5.3 hereof.

      (c) The power to  effect  any sale  under  this  Section  5.2 shall not be
   exhausted  by any one or  more  sales  as to any  portion  of the  Collateral
   remaining unsold,  but shall continue  unimpaired until all of the Collateral
   shall have been sold or all of the Secured  Obligations  shall have been paid
   in full.

      (d) Secured Party may bid for and acquire any portion of the Collateral in
   connection  with a sale  thereof  under this  Section 5.2, and may pay all or
   part of the purchase price by crediting  against amounts owing on the Secured
   Obligations, all or part of the net proceeds of such sale after deducting the
   costs, charges and expenses incurred by Secured Party in connection with such
   sale.  The Notes need not be produced  in order to complete  any such sale or
   effect  such  credit.  Secured  Party may  hold,  lease,  operate,  manage or
   otherwise deal with any property so acquired in any manner permitted by law.

      (e) Secured Party shall execute and deliver an  appropriate  instrument of
   conveyance  transferring  its  interest in any portion of the  Collateral  in
   connection  with a sale thereof  under this Section 5.2. In addition,  Debtor
   hereby irrevocably  appoints Secured Party as its agent and  attorney-in-fact
   to  transfer  and convey its  interest in any  portion of the  Collateral  in
   connection  with such a sale  thereof  and to take all  action  necessary  to
   effect such sale. No purchaser or transferee at such a sale shall be bound to
   ascertain  Secured Party's  authority,  inquire into the  satisfaction of any
   condition precedent or see to the application of any monies.

      (f)  Secured  Party's  right to seek and  recover  judgment on the Secured
   Obligations shall not be affected by the seeking, obtaining or application of
   any other relief under or with respect to this Agreement. Neither the Lien of
   this  Agreement nor any rights or remedies of Secured Party shall be impaired
   by the recovery of any  judgment by Secured  Party  against  Debtor or by the
   levy of an execution under such judgment upon any portion of the Collateral.

      (g) All rights and remedies from time to time  conferred  upon or reserved
   to the Secured Party are cumulative,  and none is intended to be exclusive of
   another and shall be in addition to every other right or remedy  permitted by
   law.  No  delay or  omission  in  insisting  upon the  strict  observance  or
   performance of any provision of this Agreement, or in exercising any right or
   remedy,  shall be construed as a waiver or  relinquishment of such provision,
   nor shall it impair  such  right or  remedy.  Every  right and  remedy may be
   exercised  from  time  to  time  and as  often  as  deemed  expedient  in any
   combination  and order  desired by Secured  Party;  provided,  however,  that
   Secured Party shall exercise none of the remedies  referenced in this Section
   5.2 with respect to the Collateral unless and until an Event of Default shall
   have occurred and be continuing.

      (h) Anything contained in this Agreement to the contrary  notwithstanding,
   until an Event of Default  shall  occur and be  continuing:  (i) all  rights,
   powers,  privileges  and other  benefits of or  accruing to Debtor  under the
   Assigned Agreements shall be exercisable only by Debtor,  without the consent
   or approval of the Secured Party, (ii) Debtor shall retain full right to make
   all  waivers  and  agreements,  to give and  receive  all  notices  and other
   instruments or communications,  and to take all action upon the occurrence of
   a default under any Assigned Agreement,  including the commencement,  conduct
   and consummation of legal,  administrative or other proceedings,  as shall be
   permitted  thereby or by law, and to do any and all other things which Debtor
   is or may be entitled to do under any Assigned Agreement.

   SECTION 5.3 Proceeds of Collateral.

   All cash  proceeds  received  by  Secured  Party in  respect  of any sale of,
collection  from, or other  realization  upon all or any part of the  Collateral
shall be held by Secured Party as collateral  for, and then promptly  thereafter
applied by Secured Party  against,  all or any part of the amounts due under the
Notes and the other  Secured  Obligations  in such order as Secured  Party shall
elect.  Any  surplus of such cash or cash  proceeds  held by  Secured  Party and
remaining  after  payment in full of all the Secured  Obligations  shall be paid
over to Debtor  or to  whomsoever  may be  lawfully  entitled  to  receive  such
surplus.

   SECTION 5.4 Waiver of Rights; Receiver.

      (a) Debtor  consents to the appointment of one or more receivers of all or
   part of the  Collateral,  upon the request of Secured  Party,  if an Event of
   Default shall have occurred and be continuing.

      (b) To the extent  permitted  by law,  Debtor  hereby  waives its right to
   seek,  and  hereby  agrees  that it will not seek or derive  any  benefit  or
   advantage  from,  any of the  following  whether now existing or hereafter in
   effect:

         (i) any stay, extension,  moratorium or similar law with respect to the
      Collateral or the Secured Obligations;

         (ii)  any  law  allowing  for  the  redemption  of any  portion  of the
      Collateral after a sale thereof under Section 5.2 hereof; and

         (iii) any right to have any portion of the Collateral after an Event of
      Default shall have occurred.

      Debtor covenants not to hinder,  delay or impede the exercise of any right
   or remedy of Secured  Party under or in respect of this  Agreement and agrees
   to suffer and permit the exercise of each such remedy.

                             INDEMNITY AND EXPENSES

   SECTION 6.1 General Indemnity.

   Debtor hereby assumes  liability  for, and does hereby agree,  whether or not
any of the transactions  contemplated hereby, by the Security Instruments or the
Notes are consummated,  to indemnify,  protect,  save,  defend and hold harmless
Secured Party and each of its  officers,  directors,  stockholders,  successors,
assigns,  agents and  servants  (for  purposes  of this  Article VI, each of the
foregoing may be referred to individually as a  "Beneficiary")  from and against
any and all obligations, fees, liabilities,  losses, damages, penalties, claims,
demands,  actions,  suits,  judgments,  costs and expenses,  including,  without
limitation,  reasonable  legal  fees  and  expenses,  of every  kind and  nature
whatsoever imposed on, incurred by, or asserted against any Beneficiary,  in any
way relating to or arising out of (a) the manufacture,  construction,  ordering,
purchase, acceptance or rejection,  financing,  ownership, titling or retitling,
registration or re-registration,  acceptance,  leasing, subleasing,  possession,
use,  operation,   maintenance,   storage,  removal,  sale,  delivery  or  other
disposition of any item of Equipment, including, without limitation, any of such
as may arise from (i) loss or damage to any  property  or death or injury to any
person,  (ii) patent or latent defects in any item of Equipment  (whether or not
discoverable  by Debtor or any  Beneficiary),  (iii) any claims  based on strict
liability in tort or  otherwise,  (iv) any claims based on patent,  trademark or
copyright  infringement and (v) any claims based on liability  arising under the
applicable  environmental or noise or pollution control law or regulation or (b)
any  failure on the part of Debtor to perform or comply with any of the terms of
the  Security  Instruments  or the Notes or (c) any Security  Instrument  or the
Notes.  Debtor shall not be required to indemnify any Beneficiary for any claims
resulting  from acts which  would  constitute  the willful  misconduct  or gross
negligence of such Beneficiary. Debtor shall give Secured Party prompt notice of
any occurrence, event or condition known to Debtor as a consequence of which any
Beneficiary  is or  is  reasonably  likely  to be  entitled  to  indemnification
hereunder.  Debtor shall promptly upon demand of any such Beneficiary  reimburse
such  Beneficiary  for  amounts  expended  by it in  connection  with any of the
foregoing  or pay  such  amounts  directly.  Debtor  shall  be  subrogated  to a
Beneficiary's  rights in any matter with  respect to which  Debtor has  actually
reimbursed such Beneficiary for amounts expended by it or has actually paid such
amounts  directly  pursuant to this  Section  6.1.  In case any action,  suit or
Proceeding  is brought  against any  Beneficiary  in  connection  with any claim
indemnified against hereunder, such Beneficiary will, after receipt of notice of
the  commencement  of such action,  suit or Proceeding,  notify Debtor  thereof,
enclosing a copy of all papers  served upon such  Beneficiary.  Debtor may,  and
upon any Beneficiary's request will, at Debtor's expense, resist and defend such
action,  suit or  Proceeding,  or cause the same to be  resisted  or defended by
counsel  selected by Debtor and reasonably  satisfactory to such Beneficiary and
in the event of any failure by Debtor to do so, Debtor shall pay all costs, fees
and expenses  (including,  without  limitation,  reasonable  attorney's fees and
expenses)  incurred by such Beneficiary in connection with such action,  suit or
Proceeding.

   SECTION 6.2 General Tax Indemnity.

   Debtor agrees to pay, and indemnify and hold each Beneficiary  harmless on an
after-tax basis from, any and all federal, state, local and foreign taxes, fees,
withholdings,  levies, imposts, duties,  assessments and charges of any kind and
nature  whatsoever,  together  with any  penalties,  fines or  interest  therein
(herein called "Taxes or Other Impositions")  howsoever imposed,  whether levied
or imposed  upon or  asserted  against  such  Beneficiary,  Debtor,  any item of
Equipment or any part  thereof,  by any federal,  state or local  government  or
taxing  authority  in  the  United  States,   or  by  any  taxing  authority  or
governmental  subdivision of a foreign country,  upon or with respect to (a) any
item  of  Equipment  (b)  the  manufacture,  construction,  ordering,  purchase,
ownership,   financing,   delivery,   leasing,   re-leasing,   possession,  use,
maintenance,  registration,  titling,  licensing,  documentation,  return,  sale
(including,  without limitation,  sale to a third party) or other application or
disposition  thereof,  (c) the payments,  receipts or earnings  arising from any
item of Equipment  or (d) the Bills of Sale,  the  Security  Instruments  or the
Notes,  or upon the payments by Debtor under the Bills of Sale, the Notes or the
Security Instruments;  provided, however, that the foregoing indemnity shall not
apply to any taxes or other  impositions to the extent based upon or measured by
any  Beneficiary's  net income (unless such tax or other imposition is a Covered
Income  Tax as  hereinafter  defined),  and which are  imposed  or levied by any
federal,  state or local  taxing  authority in the United  States.  For purposes
hereof,  a "Covered  Income  Tax" shall mean an income tax  (including,  without
limitation,  a tax  imposed  upon  gross  income  or  receipts)  imposed  on any
Beneficiary  by any  taxing  authority  (excluding  the  United  States  federal
government) in whose  jurisdiction such Beneficiary  (including for this purpose
all  entities  with which it is combined,  integrated  or  consolidated  in such
taxing  authority's  jurisdiction)  would  not  engage  in  business,  would not
maintain an office or other place of business and would not otherwise be located
therein, but for such Beneficiary's role in the transaction  associated with the
financing of the Equipment, the operation of the Equipment in such jurisdiction,
the  presence  of  Debtor  or  any  use  of the  Equipment  or the  transactions
contemplated by the Bills of Sale, the Security Instruments or the Notes.

   Each  Beneficiary  shall  furnish  Debtor  with  copies of any  requests  for
information  received by such Beneficiary from any taxing authority  relating to
any taxes or other  impositions  with  respect to which  Debtor is  required  to
indemnify  hereunder,  and if a claim is made against such  Beneficiary  for any
such taxes or other  impositions,  with  respect to which Debtor is liable for a
payment or indemnity  hereunder,  such  Beneficiary  shall give Debtor notice in
writing within (10) Business Days of such  Beneficiary's  receipt of such claim.
Debtor may, at its sole cost and expense,  either in its own name or in the name
of any  Beneficiary,  contest the validity,  applicability or amount of any such
tax or other  imposition  by means of a Permitted  Contest.  If any  Beneficiary
shall obtain a refund of any amount paid by Debtor pursuant to this Section 6.2,
such  Beneficiary  shall pay to Debtor the amount of such refund,  together with
the amount of any interest  actually  received by such Beneficiary on account of
such refund. Debtor will promptly notify Secured Party of all reports or returns
required to be made with respect to any tax or other  imposition with respect to
which Debtor is required to indemnify  hereunder and will promptly  provide each
Beneficiary  with all information  necessary for the making and timely filing of
such reports or returns by such  Beneficiary.  If any Beneficiary  requests that
any such reports or returns be prepared and filed by Debtor, Debtor will prepare
and  file  the  same if  permitted  by  applicable  law to do so,  and if not so
permitted,  Debtor shall  prepare such reports or returns for  signature by such
Beneficiary,  and shall forward the same,  together with  immediately  available
funds for payment of any tax or other  imposition due, to such  Beneficiary,  at
least ten (10)  Business Days in advance of the date such payment is to be made.
Upon written  request,  Debtor shall furnish each Beneficiary with copies of all
paid  receipts or other  appropriate  evidence of payment for all taxes or other
impositions paid by Debtor pursuant to this Section 6.2.

                                   ARTICLE VII

                 FURTHER ASSURANCES; ATTORNEY-IN-FACT; DISCHARGE

   SECTION 7.1 Further Assurances.

      (a) Debtor agrees that from time to time, at the expense of Debtor, Debtor
   will promptly execute and deliver all further instruments and documents,  and
   take all further action that Secured Party may  reasonably  deem necessary or
   desirable,  or that Secured Party may otherwise  reasonably request, in order
   to perfect and protect  any  security  interest  Granted or  purported  to be
   Granted  hereby or to enable Secured Party to exercise and enforce its rights
   and remedies  hereunder with respect to any Collateral.  Without limiting the
   generality  of the  foregoing,  Debtor  will  cooperate  to execute  and file
   financing or continuation  statements,  or amendments hereto or thereto,  and
   such  other  instruments  or  notices,  as may  be  necessary  or  reasonably
   desirable,  or as Secured Party may reasonably  request,  in order to perfect
   and  preserve  the  security  interests  Granted or  purported  to be Granted
   hereby.

      (b) A carbon,  photographic or other reproduction of this Agreement or any
   financing  statement  covering the  Collateral  or any part thereof  shall be
   sufficient as a financing statement where permitted by law.

      (c) Debtor will furnish to Secured Party from time to time  statements and
   schedules  further  identifying  and describing the Collateral and such other
   reports in connection  with the  Collateral  as Secured Party may  reasonably
   request, all in reasonable detail.

   SECTION 7.2 Secured Party Appointed Attorney-in-Fact.

   Debtor  hereby  irrevocably  appoints  Secured  Party to  serve  as  Debtor's
attorney-in-fact  (provided, the parties hereto agree that Secured Party may not
act  as  Debtor's   attorney-in-fact   until  the   occurrence  and  during  the
continuation of an Event of Default), with full authority in the place and stead
of Debtor and in the name of Debtor,  Secured Party or  otherwise,  from time to
time in Secured  Party's  discretion,  to take any  action  and to  execute  any
instrument,  including  without  limitation  financing  statements or amendments
thereto,  which Secured Party may deem  necessary or advisable to accomplish the
purposes of this Agreement, including without limitation:

      (a) to obtain and adjust  insurance  required to be paid to Secured  Party
   hereunder;

      (b) to ask, demand, collect, sue for, recover,  compound, receive and give
   acquittance and receipts for monies due and to become due under or in respect
   of any of the Collateral;

      (c) to receive,  endorse,  and  collect  any drafts or other  instruments,
   documents and chattel paper, in connection with subsections (a) or (b) above;
   and
<PAGE>

      (d) to file any claims or take any  action or  institute  any  Proceedings
   which Secured Party may deem necessary or desirable for the collection of any
   of the  Collateral  or otherwise to enforce the rights of Secured  Party with
   respect to any of the Collateral.

   SECTION 7.3 Secured Party May Perform.

   If Debtor fails to perform any agreement contained herein,  Secured Party may
itself perform,  or cause  performance  of, such agreement,  and the expenses of
Secured Party incurred in connection  therewith shall be payable by Debtor under
Section 6.1.

   SECTION 7.4 Secured Party's Duties.

   The powers  conferred on Secured  Party  hereunder  are solely to protect its
interest in the Collateral and shall not impose any duty upon it to exercise any
such powers.  Secured Party shall have no duty as to any Collateral or as to the
taking of any necessary  steps to preserve  rights  against other parties or any
other rights pertaining to any Collateral.

   SECTION 7.5 Continuing Security Interest; Transfer of Note; Termination.

   This  Agreement  shall:  (a) create a  continuing  security  interest  in the
Collateral  and shall remain in full force and effect  until  payment in full of
the Secured Obligations,  be binding upon Debtor, its successors and assigns and
(b)  inure  to the  benefit  of  Secured  Party  and its  permitted  successors,
transferees  and assigns.  Without  limiting  the  generality  of the  foregoing
clause,  Secured  Party may  assign  or  otherwise  transfer  all or any part of
Secured Party's interest in the Notes and/or the Security  Instruments to one or
more persons or entities,  and such other  persons or entities  shall  thereupon
become vested with all the benefits in respect  thereof Granted to Secured Party
herein.  Upon the  payment  in full of the  Secured  Obligations,  the  security
interest  Granted hereby shall terminate and all rights to the Collateral  shall
revert to Debtor.  Upon any such  termination,  Secured  Party will  execute and
deliver to Debtor such documents as Debtor shall reasonably  request to evidence
such termination.

   Debtor shall bear all risk of any loss of or damage to the  Collateral and in
no event shall Secured Party be liable for such loss or damage.

   SECTION 8.3 Powers and Agencies.

   Whenever in this  Agreement  Secured  Party or Debtor is Granted the power of
attorney or is  appointed  the agent and  attorney-in-fact  with  respect to any
Person,  such Grant or appointment is irrevocable  and coupled with an interest.
Secured Party shall have full power of substitution and delegation in respect of
all such Grants and appointment.

   SECTION 8.4 Entire Agreement.

   The Notes,  this  Agreement  and the other  Security  Instruments  embody the
entire  agreement  between the parties and  supersede all prior  agreements  and
understandings, if any, relating to the subject matter hereof.

   SECTION 8.5 Lawful Interest.

   No provision in the Notes, this Agreement or any Security Instrument or other
document in favor of Secured  Party shall  require or permit the  collection  of
interest in excess of the maximum  lawful rate which  Debtor may  contract  for,
stipulate or agree to pay as  determined  by a court of  competent  jurisdiction
over the holder of the Notes or any such document. In determining whether or not
the interest paid or payable under any specific contingency exceeds such maximum
lawful rate,  Debtor and Secured  Party shall,  to the full extent  permitted by
applicable law,  prorate,  allocate and spread, in equal parts, the total amount
of  interest  throughout  the  entire  contemplated  term of the  Notes or other
document,  as the case may be, so that the interest  rate is uniform  throughout
the entire term of the Notes or such document.  If it is so determined  that any
interest in excess of such  maximum  lawful rate is  provided  for,  such excess
shall be applied  first to any other  amounts not  constituting  interest due or
which may become due and payable to Debtor  under the Notes or any of such other
documents,  and the  balance,  if any,  shall be refunded  to Debtor;  provided,
however,  that in no event shall Debtor be  obligated to pay, and Secured  Party
hereby  waives  payment of, the amount of interest to the extent it is in excess
of the amount permitted by applicable law.

   SECTION 8.6 Survival; Severability.

   If any word,  phrase,  sentence,  paragraph,  provision  or  section  of this
Agreement, the Notes or any other Security Instrument shall be held, declared or
pronounced void, voidable, invalid,  unenforceable or inoperative for any reason
by any court of competent  jurisdiction,  governmental  authority or  otherwise,
such holding,  declaration or pronouncement shall not adversely affect any other
word, phrase, sentence,  paragraph,  provision or section of this Agreement, the
Notes or any other Security  Instrument,  which shall  otherwise  remain in full
force and effect and be enforced in accordance with their respective  terms, and
the effect of such holding, declaration or pronouncement shall be limited to the
territory  or  the  jurisdiction  in  which  made.  All  agreements,  covenants,
representations,  warranties and conditions  contained in this Agreement or made
pursuant to the  provisions  hereof shall  survive the execution and delivery of
this Agreement until the Secured  Obligations shall have been paid and performed
in  full.  All  statements  by  Debtor  contained  in any  certificate  or other
instrument  delivered  pursuant to the provisions of this Agreement or any other
Security  Instrument  shall  constitute  the  representations  and warranties of
Debtor.

   SECTION 8.7 Binding Effect.

   This  Agreement  shall be binding upon and inure to the benefit of Debtor and
Secured Party and their  respective  successors and assigns,  except that Debtor
shall not have the right to assign its rights  hereunder of any interest  herein
without the prior written consent of Secured Party. Secured Party may assign all
or any part of, or any interest in, its rights and benefits hereunder, under the
Notes and any Security  Instrument as permitted under Section 7.5 hereof, and to
the extent of such permitted  assignment  each such assignee shall have the same
rights and benefits against Debtor as it would have had if it were Secured Party
hereunder.

   SECTION 8.8 Amendment and Waiver.

   No amendment or waiver of any provision of the Notes,  this  Agreement or any
of the  other  Security  Instruments,  or  consent  to any  departure  by Debtor
therefrom,  shall in any event be effective  unless the same shall be in writing
and signed by Secured  Party and Debtor,  and such  waiver and consent  shall be
effective only in the specific  instance and for the specific  purpose for which
given.  No  failure on the part of Secured  Party to  exercise,  and no delay in
exercising,  any  right  under the  Notes,  this  Agreement  or any of the other
Security  Instruments shall operate as a waiver thereof; nor shall any single or
partial  exercise of any right under any such  instrument or agreement  preclude
any other or further exercise thereof or the exercise of any other right.

   SECTION 8.9 Headings; Execution in Counterpart.

   The section and article  headings  herein are for  convenience  of  reference
only,  and shall not limit or  otherwise  affect the  meaning  of any  provision
herein.  This  Agreement  may be executed in  counterparts,  each of which shall
constitute an original,  but all of which together shall  constitute one and the
same Agreement.

   SECTION 8.10 Transaction Costs.

   Debtor shall pay all reasonable costs and  out-of-pocket  expenses of Secured
Party  incurred  in  connection  with   preparation,   negotiation,   execution,
modification and/or enforcement of the Notes, this Agreement, the other Security
Instruments  including  without  limitation  (a) the  reasonable  legal fees and
expenses of Moore & Van Allen, PLLC, (b) all filing and registration  costs, (c)
all fees and  disbursements  incurred by Secured  Party in  connection  with the
custody,  preservation, use or operation of, or the sale of, collection from, or
other  realization   upon,  any  of  the  Collateral,   and  (d)  all  fees  and
disbursements incurred by Secured Party in connection with the failure by Debtor
to perform or observe any of the provisions hereof.

   SECTION 8.11 APPLICABLE LAW;  CONSENT TO  JURISDICTION  AND VENUE;  WAIVER OF
JURY TRIAL.

   THIS AGREEMENT,  THE NOTES AND THE OTHER SECURITY INSTRUMENTS AND ALL MATTERS
RELATING THERETO SHALL,  EXCEPT TO THE EXTENT  OTHERWISE  REQUIRED BY APPLICABLE
LAW, BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NORTH  CAROLINA  WITHOUT  REGARD TO  CONFLICT  OF LAWS  PRINCIPLES.
DEBTOR  HEREBY  SUBMITS TO THE  JURISDICTION  AND VENUE OF THE STATE AND FEDERAL
COURTS OF MECKLENBURG COUNTY,  NORTH CAROLINA AND AGREES THAT SECURED PARTY MAY,
AT ITS  OPTION,  ENFORCE  ITS  RIGHTS  HEREUNDER  AND  UNDER THE NOTES AND OTHER
SECURITY  INSTRUMENTS  IN SUCH  COURTS.  DEBTOR  HEREBY  IRREVOCABLY  WAIVES THE
DEFENSE OF AN  INCONVENIENT  FORUM TO MAINTENANCE OF ANY ACTION OR PROCEEDING BY
SECURED PARTY IN SUCH COURTS.  DEBTOR HEREBY  IRREVOCABLY  WAIVES, TO THE EXTENT
PERMITTED  BY  APPLICABLE  LAW,  ALL  RIGHT  TO  TRIAL  BY JURY  IN ANY  ACTION,
PROCEEDING OR  COUNTERCLAIM  ARISING OUT OF OR RELATING TO THIS  AGREEMENT,  THE
NOTES OR ANY OTHER SECURITY  INSTRUMENT OR ANY OF THE TRANSACTIONS  CONTEMPLATED
HEREBY OR THEREBY.

   SECTION 8.12 Break-Funding Costs.

   Upon any early  termination of this Agreement  and/or any early prepayment of
the Notes for any  reason  which is not  expressly  permitted  under the  Notes,

SIXTY-EIGHT AND 14/100 DOLLARS ($557,768.14) (the "Original Amount") pursuant to
the terms and conditions of that certain Loan and Security Agreement dated as of
the date hereof between the Debtor and the Secured Party,  as amended,  modified
or  replaced  from  time to time  (as so  amended,  modified  or  replaced,  the
"Agreement"  - all the terms,  conditions,  definitions  and  covenants  of such
Agreement are expressly  made a part hereof in the same manner and with the same
effect as if set forth herein at length,  any holder of this Secured Term Note A
(the "Note")  being  entitled to the  benefits and remedies  provided for in the
Agreement).

         The Bank has made a term loan to the  Borrower  as  provided in Section
1.3(a) of the Loan Agreement.  The outstanding principal balance hereof shall be
due  and  payable  as  provided  in  Section   1.3(a)(ii)   of  the   Agreement.
Notwithstanding  the foregoing,  the final payment made on this Note shall be an
amount  sufficient  to  discharge  in full the  unpaid  Original  Amount and all
accrued and unpaid  interest  on, and any other  amounts due under this Note and
under the Agreement.

         This Note shall bear interest on the outstanding  balance  hereof,  and
such interest shall be payable  hereunder,  as provided in Section 1.3(a)(ii) of
the Agreement.

         In the event the amounts owing under this Note shall be  accelerated in
accordance  with the terms of the Agreement,  the amounts owing  hereunder shall
become  immediately due and payable  without  presentation,  demand,  protest or
notice of any kind, all of which are hereby expressly  waived.  Further,  in the
event amounts owing  hereunder  are not paid when due  (including  any stated or
accelerated  maturity),  the  Debtor  agrees to pay  promptly  upon  demand,  in
addition to principal,  interest and other amounts owing hereunder, all costs of
collection, including reasonable attorneys' fees.

and Secured Party shall, to the full extent permitted by applicable law, exclude
voluntary prepayment and the effects thereof and amortize, prorate, allocate and
spread,  in equal  parts,  the total  amount of interest  throughout  the entire
contemplated  term of this Note so that the interest rate is uniform  throughout
the entire term of this Note. If it is so determined that any interest in excess
of such maximum  lawful rate is provided  for, then such excess shall be applied
first to any other amounts not constituting interest due or which may become due
under this Note or the Agreement and the balance,  if any,  shall be refunded to
Debtor;  provided,  however,  that in no event shall Debtor be obligated to pay,
and Secured Party hereby waives payment of, the amount of interest to the extent
it is in excess of the amount  permitted by applicable law. No provision in this
Note or the  Agreement  shall  require or permit the  collection  of interest in
excess of the maximum lawful rate.

         This Note may be  prepaid  by the  Debtor in  accordance  with  Section
1.3(c) of the  Agreement  only if all amounts  owing with  respect to this Note,
Agreement  and the  other  Security  Instruments  are  paid in full.  Except  as
otherwise  provided  for  herein  and in the  Agreement,  this Note shall not be
subject to prepayment.

                                    GUARANTY


         THIS GUARANTY  AGREEMENT dated as of February 6, 1997 (the  "GUARANTY")
is given by SEITEL,  INC., a Delaware corporation (the "GUARANTOR") and extended
to  NATIONSBANC  LEASING  CORPORATION  OF  NORTH  CAROLINA,   a  North  Carolina
corporation (the "SECURED PARTY"), for the benefit of EAGLE GEOPHYSICAL, INC., a
DELAWARE corporation (the "DEBTOR").

         Capitalized  terms used herein but not otherwise defined shall have the
meaning set forth in the Loan and  Security  Agreement  (as defined  below).  In
consideration  of the  execution  by the Secured  Party of the Loan and Security
Agreement  dated as of the date hereof (as renewed,  extended,  supplemented  or
amended,  and together  with all exhibits and schedules  thereto,  the "LOAN AND
SECURITY  AGREEMENT") with Debtor, and to induce Secured Party to enter into the
Loan and Security Agreement, Guarantor hereby agrees as follows:

         SECTION   1.   UNCONDITIONAL    GUARANTEE.    Guarantor   does   hereby
unconditionally guarantee to Secured Party, without offset or deduction, (a) the
prompt payment when due,  whether by acceleration  or otherwise,  of all amounts
payable by Debtor pursuant to (i) the Loan and Security Agreement (including all
supplements  and  amendments  thereto  and all  exhibits  and  schedules  now or
hereafter attached thereto and made a part thereof),  (ii) the Secured Term Note
A dated  February 6, 1997 ("TERM NOTE A") in the  original  principal  amount of
$557,768.14  extended by Debtor for the benefit of Secured Party,  (iii) Secured
Term Note B dated  February 6 , 1997 ("TERM NOTE B") in the  original  principal
amount of  $7,006,152.04  extended  by Debtor for the  benefit of Secured  Party
(collectively,  Term Note A and Term Note B may be referred to as the  "NOTES"),
and (iv) all agreements,  instruments and documents delivered or to be delivered
by  Debtor  pursuant  to the  Loan  and  Security  Agreement  and/or  the  Notes
(collectively,  the  Loan and  Security  Agreement,  the  Notes  and such  other
agreements,  instruments  and  documents  may  be  referred  to  herein  as  the
"TRANSACTION  DOCUMENTS"),  the  guarantee  under  this  clause (a) of Section 1
constituting a guarantee of payment and not of collection,  and (b) the punctual
and faithful performance by Debtor of each and every duty,  agreement,  covenant
and  obligation  of  Debtor  under  and in  accordance  with  the  terms  of the
Transaction  Documents  and all other  obligations  of Debtor to Secured  Party.
Guarantor  does hereby  agree that in the event  Debtor does not or is unable to
pay or perform in accordance with the terms of the Transaction Documents for any
reason   (including,   without   limitation,   the   liquidation,   dissolution,
receivership,  insolvency,  bankruptcy, assignment for the benefit of creditors,
reorganization,  arrangement,  composition or readjustment  of, or other similar
proceedings affecting the status, existence,  assets or obligations of Debtor or
the  limitation  of  damages  for  the  breach,  or the  disaffirmance  of,  any
Transaction Documents in such proceeding) it will pay the sums, or amounts equal
thereto,  which Debtor is (or, but for any such reason,  would be)  obligated to
pay at the times specified in the Transaction Documents, whether by acceleration
or otherwise (it being the intention  hereof that Guarantor shall pay to Secured
Party,  as a payment  obligation  directly due from  Guarantor to Secured Party,
amounts equal to all amounts which Debtor shall fail  faithfully and properly to
pay when due  under  the  Transaction  Documents,  whether  by  acceleration  or
otherwise),  or  otherwise  provide for and bring about  promptly  when due such
payment  and  the  performance  of  such  duties,   agreements,   covenants  and
obligations of Debtor under the Transaction  Documents.  Guarantor  acknowledges
that it is fully aware of, and consents to the terms and conditions of, the Loan
and Security  Agreement,  the Notes and each of the other Transaction  Documents
and guarantees the accuracy of all  representations  and warranties of Debtor or
any officer  thereof made,  or to be made after the date hereof,  in any of such
Transaction   Documents.   The  obligations  of  Debtor  hereby  guaranteed  are
hereinafter called the "SECURED OBLIGATIONS".

         SECTION 2. DIRECTNESS OF OBLIGATION. Without limiting the generality of
clause (a) of  Section 1,  Guarantor  specifically  agrees  that it shall not be
necessary or required, and that Guarantor shall not be entitled to require, that
Secured  Party  file suit or  proceed  to obtain or assert a claim for  personal
judgment  against  Debtor  for the  Secured  Obligations  or make any  effort at
collection of the Secured  Obligations from Debtor or foreclose  against or seek
to  realize  upon  any  security  now or  hereafter  existing  for  the  Secured
Obligations  or file suit or  proceed  to obtain or assert a claim for  personal
judgment against any other party liable for the Secured  Obligations or make any
effort at  collection  of the Secured  Obligations  from any such other party or
exercise  or assert any other  right or remedy to which it is or may be entitled
in connection  with the Secured  Obligations or any security or other  guarantee
therefor  or assert or file any claim  against the assets of Debtor or any other
person liable for the Secured Obligations,  or any part thereof,  before or as a
condition  of  enforcing  the  liability  of  Guarantor  under this  Guaranty or
requiring payment of said Secured Obligations by Guarantor hereunder,  or at any
time  thereafter.  Fulfillment  by Debtor  or  Guarantor  of any of the  Secured
Obligations  shall  dispose of any claim  hereunder  with respect to, and to the
extent of, such of the  Secured  Obligations  fulfilled.  Without  limiting  the
generality of the waiver provisions  hereof,  Guarantor hereby waives any rights
to require  Secured Party to proceed  against Debtor or any  co-guarantor  or to
require  Secured  Party to pursue any other  remedy or enforce any other  right,
including any and all rights under ss.26-7 through ss.26-9 of the North Carolina
General   Statutes.   The  Guarantor   shall  have  no  rights  of  subrogation,
reimbursement or indemnity whatsoever, nor any right or recourse to security for
the debts and  obligations  of  Debtor  to  Secured  Party so long as any of the
Secured  Obligations shall remain  outstanding.  Guarantor does hereby waive and
relinquish,  so far as Guarantor may lawfully and effectively do so, the benefit
and  advantage  of any and  all  valuation,  stay,  appraisement,  extension  or
redemption laws which,  but for this provision,  agreement and waiver,  might be
applicable to any sale made under any judgment,  order or decree of any court or
otherwise based on this Guaranty,  the Loan and Security  Agreement or any other
Agreement.

         SECTION 3. WAIVER OF NOTICE AND  DEFENSE.  This  Guaranty  shall not be
deemed  to create  any  right in any  person  except  as  provided  herein or be
construed in any respect to be a contract in whole or in part for the benefit of
any other person except Secured Party and its  successors or assigns.  Guarantor
specifically  agrees  that it shall not be  necessary  or  required  in order to
enforce the obligations of Guarantor  hereunder that there be, and  specifically
waives (a) notice of the  acceptance of this Guaranty and of the  performance or
nonperformance  of the Loan  and  Security  Agreement,  the  Notes or any  other
Transaction  Documents,  (b) demand of payment from Debtor,  (c) presentment for
payment  upon Debtor or the making of any  protest,  (d) notice of the amount of
the Secured  Obligations  outstanding  at any time,  (e) notice of nonpayment or
failure to perform on the part of Debtor,  and (f) any other  circumstance which
might  otherwise  constitute  a legal or  equitable  defense or  discharge  of a
guarantor.

         SECTION 4. OBLIGATIONS - ABSOLUTE AND UNCONDITIONAL. The obligations of
Guarantor  under this  Guaranty  shall be absolute and  unconditional  and shall
remain in full force and effect  until Debtor  shall have fully  discharged  the
Secured  Obligations  and shall not be  released  or  discharged  for any reason
whatsoever,  including,  without  limitation,  the following:  (a) the waiver by
Secured Party, or its successors or assigns, of the performance or observance by
Debtor of any of the agreements, covenants, terms or conditions contained in the
Transaction Documents, or any default thereunder,  (b) the extension of time for
payment by Debtor of any sums or any part  thereof  owing or  payable  under any
Transaction  Document,  or of the time for  performance  by  Debtor of any other
obligations  under or arising out of or on account of any Transaction  Document,
or the  extension  or  renewal of any  Transaction  Document,  (c) any  failure,
omission  or delay of Secured  Party to enforce,  assert or exercise  any right,
power or remedy  conferred on Secured Party in any action on the part of Secured
Party  granting  extension  or  indulgence  in any  form,  (d) any  transfer  or
assignment by Debtor or Secured Party of its interest,  or any part thereof,  in
and to any  Collateral  (as  such  term is  defined  in the  Loan  and  Security
Agreement) as permitted by the Loan and Security Agreement,  (e) any compromise,
settlement,  release,  renewal,  extension,  indulgence,  change in or waiver or
modification  of any of the Secured  Obligations  or the release or discharge of
Debtor from the  performance or observance of any of the Secured  Obligations by
operation of law, (f) any  assignment or mortgaging or the purported  assignment
or  mortgaging  of all or any part of the  interest  of  Debtor  in the Loan and
Security  Agreement  or in any  Collateral,  (g) the  voluntary  or  involuntary
liquidation,  dissolution, sale or other disposition of all or substantially all
the assets and  liabilities  of, or the voluntary or  involuntary  receivership,
insolvency, bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement,  composition  or  readjustment  of,  or  other  similar  proceeding
affecting, Debtor or the disaffirmance of the Loan and Security Agreement in any
such proceeding, (h) any merger,  consolidation or other reorganization to which
Debtor,  Guarantor or any related entity is a party, or any sale or disposition,
whether  directly  or  indirectly,  of any of  Guarantor's  direct  or  indirect
ownership interest in Debtor, or (i) any other circumstance,  whether similar or
dissimilar  to any of the above,  which might  otherwise  constitute  a legal or
equitable defense or discharge of a guarantor.

         SECTION  5.  REPRESENTATIONS,   WARRANTIES  AND  COVENANTS.   Guarantor
represents,  warrants  and  covenants  to  and  with  Secured  Party  all of the
following:  (a)  Guarantor  is  duly  organized,  validly  existing  and in good
standing  under the laws of the state in which it is  incorporated,  and is duly
qualified and authorized to do business wherever the nature of its activities or
