                               EMPLOYMENT WARRANTS


This  Prospectus  is being used in connection  with the  offering,  from time to
time, by certain stockholders (the "Selling  Stockholders") of Seitel, Inc. (the
"Company")  of shares of common  stock,  $.01 par value per share  (the  "Common
Stock") which may be acquired  upon  exercise of options  granted under the 1993
Incentive  Stock  Option  Plan (the  "Option  Plan"),  upon  exercise of certain
warrants (the "Executive  Warrants") granted to the Selling Stockholders as part
of the Company's 1997 Executive  Compensation Plan (the "Executive  Compensation
Plan"),  and upon  exercise  of certain  warrants  (the  "Employment  Warrants")
granted  to a Selling  Stockholder  in  connection  with his  employment  by the
Company.

The securities being registered hereby (the "Securities") may be sold, from time
to time, by the Selling  Stockholders,  directly or  indirectly,  through agents
designated from time to time, in one or more open market transactions, including
block  trades,  on  the  New  York  Stock  Exchange,   in  privately  negotiated
transactions,  or in a  combination  of such methods of sale.  Such sales may be
made through dealers or underwriters to be designated, on terms to be determined
at the time of sale,  or at prices  and at terms  then  prevailing  or at prices
related to the then current market price. In effecting sales, brokers or dealers
engaged by the Selling  Stockholders may arrange for other brokers or dealers to
participate.  Brokers or dealers will  receive  commissions  or  discounts  from
Selling Stockholders in amounts to be negotiated  immediately prior to the sale.
Such  brokers or dealers and any other  participating  brokers or dealers may be
deemed to be "underwriters" within the meaning of the Securities Act of 1933, as
amended (the  "Securities  Act"),  in connection  with such sales. To the extent
required,  the specific  securities sold, the name of the Selling  Stockholders,
the purchase price,  public offering  price,  name of any such agent,  dealer or
underwriter,  and any  applicable  discount  or  commission  with  respect  to a
particular  offer  will  be set  forth  by  supplement  to this  Prospectus.  In
addition,  any  securities  covered by this  Prospectus  which  qualify for sale
pursuant  to Rule 144 may be sold under Rule 144 rather  than  pursuant  to this
Prospectus.  The Company will not receive any of the  proceeds  from the sale of
these  shares,  but will  receive  the  aggregate  exercise  price  of  warrants
exercised  under the Option Plan,  the  Executive  Warrants  and the  Employment
Warrants.  The Company's  Common Stock is presently listed on the New York Stock
Exchange  under the symbol  "SEI." The closing price for the Common Stock on the
New York Stock Exchange on September 25, 1998, was $11.50.

                                  RISK FACTORS

Prospective  purchasers  of the  Common  Stock  should  carefully  consider,  in
addition  to  the  other  information  contained  in  this  Prospectus  and  any
accompanying Prospectus Supplement, the following risk factors.

Competition.  Competition in the seismic data licensing  industry and in the oil
and gas exploration and production  industry is intense. A number of independent
oil-service  companies  create and market seismic data, and numerous oil and gas
companies  create seismic data and maintain their own seismic data banks. Due to
difficult industry conditions in recent years, the number of independent seismic
companies has  decreased,  and oil and gas companies have acquired an increasing
portion of their seismic data from outside  sources,  including the Company.  In
the oil and gas exploration and production business,  there are numerous oil and
gas companies competing for the acquisition of mineral properties.  Although the
Company  has  significant  operating  history  in  its  seismic  data  licensing
operations, it has limited operating history in oil and gas exploration. Some of
the Company's  competitors have longer operating  histories,  greater  financial
resources  and larger  sales  volumes  than the  Company.  Although  the Company
believes that its fully-integrated seismic resources and technical,  geophysical
and marketing expertise will allow it to compete effectively in both the seismic
data industry and the oil and gas exploration and  development  industry,  there
can be no assurance that this will be the case.

Industry  Conditions.  Demand for the Company's  seismic data depends  primarily
upon the level of spending by oil and gas companies for exploration,  production
and development activities.  These spending levels tend to increase and decrease
with  increases and  decreases in the commodity  prices for oil and gas, so that
demand for the  Company's  seismic  data is  affected  to some  degree by market
prices  for  natural  gas and  crude  oil,  which  have  historically  been very
volatile.  Revenues  generated  by the  Company's  oil and gas  exploration  and
development  business  increase and decrease with increases and decreases in the
market prices of oil and gas. A substantial  or extended  decline in oil and gas
prices could have a material adverse effect on the Company's financial position.
In  addition,  if oil and gas prices  decrease  materially,  the  Company may be
unable to find partners  willing to pay the relatively high costs of exploration
and  development and grant the Company an interest in production in exchange for
seismic  data.  Further,  as high quality 3D data becomes more widely  available
from  other  sources,  the  Company  may be unable to obtain  the same  level of
working  interests in oil and gas properties in exchange for use of its 3D data.
Also,  other  factors  beyond the  Company's  control may affect its oil and gas
operations.  These  factors  include the level of supply of natural gas and oil,
the availability of adequate  pipeline and other  transportation  and processing
facilities and the marketing of competitive  fuels.  See also  "Compliance  with
Governmental Regulations."

Operating  Risks.  The Company's oil and gas  operations  are subject to hazards
incident to the drilling of oil and gas wells,  such as  cratering,  explosions,
uncontrollable  flows of oil, gas or well  fluids,  fires,  pollution,  or other
environmental  risks,  as well as to the risk  that no  commercially  productive
natural gas or oil reserves will be encountered. Some of these hazards can cause
personal  injury and loss of life,  severe damage to and destruction of property
and equipment,  environmental damage and suspension of operations.  In addition,
the cost of drilling,  completing and operating  wells is often  uncertain,  and
drilling  operations  may be  curtailed,  delayed or  canceled  as a result of a
variety of  factors,  including  unexpected  drilling  conditions,  pressure  or
irregularities  in  formations,   equipment   failures  or  accidents,   weather
conditions and shortages or delays in the delivery of equipment. These risks are
typically shared by the Company and its petroleum company partners.  The Company
also seeks to reduce dry hole risks by utilizing 3D seismic  data,  where deemed
appropriate,  to assist in the determination of where to drill.  However,  since
the Company does not act as operator in its oil and gas drilling business, it is
dependent upon its petroleum company partners to conduct  operations in a manner
so as to minimize these operating  risks. In accordance with industry  practice,
the Company  maintains  insurance  against some, but not all, of these operating
risks.  There can be no assurance  that adequate  insurance will be available in
the future, or that the Company will be able to maintain  adequate  insurance on
terms and conditions it finds  acceptable.  As a result of the risks inherent in
oil and gas  operations,  there can be no  assurance  as to the  success  of the
Company's oil and gas exploration, development and production activities.

Holding Company  Structure.  The Company has no operations or significant assets
other than  through  its  ownership  of the capital  stock of its  subsidiaries.
Dividends  and  other  permitted  payments  from such  subsidiaries  will be the
primary source of funds to pay dividends on the Common Stock.  The rights of the
Company and its creditors to participate  in the assets of any  subsidiary  upon
the latter's  liquidation or reorganization  will be subject to the prior claims
of the  subsidiary's  creditors except to the extent that the Company may itself
be a creditor with recognized claims against the subsidiary.
<PAGE>

Dependence on Key  Personnel.  The  Company's  operations  are dependent  upon a
relatively small group of management and technical personnel. The loss of one or
more of these  individuals  could have a material adverse effect on the Company.
The Company utilizes equity ownership and other incentives to attract and retain
its employees. In addition, the Company's President and Chief Executive Officer,
Paul A. Frame,  Executive Vice President and Chief Operating Officer,  Horace A.
Calvert, and Senior Vice President-Finance and Chief Financial Officer, Debra D.
Valice, all have employment agreements with the Company.

Geographic  Concentration of Operations.  Most of the Company's  seismic data in
its seismic data library, as well as most of the Company's existing interests in
oil and gas  properties,  are located  along the coast and  offshore in the U.S.
Gulf of Mexico. Because of this concentration, any regional events that increase
costs,  reduce  availability  of equipment or supplies,  reduce  demand or limit
production  will impact the Company more adversely than if the Company were more
geographically diversified.

Compliance with Governmental Regulations. The oil and gas industry in general is
subject to extensive governmental regulation,  which may be changed from time to
time in response to economic or political conditions. In particular, oil and gas
exploration and production is subject to federal and state regulations governing
environmental quality and pollution control,  state limits on allowable rates of
production by well or proration unit, and other similar  regulations.  State and
federal  regulations  generally are intended to prevent waste of natural gas and
oil,  protect  rights to produce  natural gas and oil between owners in a common
reservoir,  control  the amount of natural  gas and oil  produced  by  assigning
allowable  rates of production  and control  contamination  of the  environment.
Also,  the Company  believes  that the trend toward more  expansive and stricter
environmental laws and regulations will continue.  The implementation of new, or
the  modification  of existing,  laws or  regulations  affecting the oil and gas
industry could have a material adverse impact on the Company.

Shares Eligible for Future Sale. No prediction can be made as to the effect,  if
any,  that  future  sales of  shares  of the  Company's  capital  stock,  or the
availability  of shares of capital stock for future sale will have on the market
price  of  such  stock  prevailing  from  time  to  time.   Almost  all  of  the
approximately  4.6 million shares of Common Stock  currently held by or issuable
pursuant to options,  warrants and other rights granted prior to the date hereof
and exercisable within 60 days of the date hereof to the Company's directors and
executive officers are eligible for sale currently or immediately upon exercise.
Sales of substantial  amounts of Common Stock (including  shares issued upon the
exercise of stock options or warrants),  or the perception that such sales could
occur, could adversely affect prevailing market prices for the Common Stock.

                DISCLOSURE REGARDING FORWARD-LOOKING INFORMATION

This  Prospectus  includes  "forward-looking  statements"  within the meaning of
Section  27A of the  Securities  Act and Section 21E of the  Exchange  Act.  All
statements   other  than  statements  of  historical   facts  included  in  this
Prospectus,  including without  limitation,  statements  regarding the Company's
financial  position,   business  strategy,  budgets,  plans  and  objectives  of
management  for future  operations  are  forward-looking  statements.  The words
"anticipate,"  "believe,"  "expect,"  "plan," "intend,"  "estimate,"  "project,"
"will,"  "could," "may," "predict" and similar terms and phrases are intended to

uncertainties  that may cause actual future activities and results of operations
to be materially different from those suggested or described in this Prospectus.
Although  the  Company  believes  that  the   expectations   reflected  in  such

Statements")   are  disclosed   under  "Risk  Factors"  and  elsewhere  in  this
Prospectus.  Should one or more of these risks or uncertainties materialize,  or
should  underlying   assumptions  prove  incorrect,   actual  results  may  vary
materially from those expected,  estimated or projected.  All subsequent written
and oral  forward-looking  statements  attributable  to the Company,  or persons
acting  on  its  behalf,  are  expressly  qualified  in  their  entirety  by the

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.

The Company's  integrated  seismic data  operations  include its large 2D and 3D
seismic library,  its seismic data processing center and computer software,  and
the Company's geophysical application experience in interpreting 3D data.

In  March  1993,  the  Company  formed  DDD  Energy,  Inc.  ("DDD  Energy"),   a
wholly-owned  subsidiary,  to  participate  directly in  petroleum  exploration,
development  and  ownership  of  hydrocarbon  reserves  through cost and revenue
sharing relationships with oil and gas producers.  The Company's objective is to
participate  through DDD Energy in exploration  and  development  programs which
combine  the  Company's  3D and 2D seismic  resources  and  related  geophysical
technologies  with the geology and  engineering  expertise and land positions of
selected petroleum producers.

                                 USE OF PROCEEDS

The  Company  will not  receive  any part of the  proceeds  from the sale of the
shares of Common Stock by the Selling  Stockholders.  The Company will, however,
receive  the  exercise  price of  options  granted  under the Option  Plan,  the
Executive  Warrants and the  Employment  Warrants upon exercise  thereof,  which
options and warrants must be exercised before the Selling  Stockholders can sell
the shares offered  hereunder.  The exercise price of the Executive  Warrants is
$20.50 per share. The exercise price of the 915,064 options  previously  granted
under the amendments to the Option Plan to which this  prospectus  relates range
from  $17.1875  per share to $21.50 per  share,  and the  exercise  price of the
784,936  options that may be granted in the future under the  amendments  to the
Option Plan to which this  prospectus  relates  will  determined  at the time of
grant of such options.  The Exercise Price of 81,103 of the Employment  Warrants
is $15.875,  and the exercise price of the remaining 150,000 Employment Warrants
will be determined at the time certain  criteria are met. The Company intends to
use the  proceeds  from the  exercise of such  options and  warrants for general
corporate purposes.

                              PLAN OF DISTRIBUTION

All Securities  covered by this Prospectus are being offered for the accounts of
the Selling Stockholders.  The Securities may be sold, from time to time, in one
or more transactions at a fixed offering price, which may be changed, at varying
prices  determined  at the time of sale,  at terms then  prevailing or at prices
related to the then current market price or at negotiated prices. The Securities
may be  sold in one or more  open  market  transactions  on the New  York  Stock
Exchange or in privately negotiated transactions.  The Securities may be sold by
various methods,  including, but not limited to, one or more of the following: a
block  trade in which  the  broker or dealer so  engaged  will  attempt  to sell
Securities  as agent  but may  position  and  resell a  portion  of the block as
principal  to  facilitate  the  transaction,  purchases by a broker or dealer as
principal  and resale by the broker or dealer for its own  account  pursuant  to
this Prospectus, a transaction on the New York Stock Exchange in accordance with
the rules of such exchange,  and ordinary brokers  transactions and transactions
in  which  the  broker  solicits  the  purchasers.  Alternatively,  the  Selling
Stockholder  may from time to time offer the  securities  through  underwriters,
dealers  or agents  who may  receive  compensation  in the form of  underwriting
discounts,  concessions,  or commissions  from the Selling  Stockholders  and/or
purchasers of Securities  for whom they act as agents.  In addition,  any of the
Securities which qualify for sale pursuant to Rule 144 under the Securities Act,
or otherwise  pursuant to an applicable  exemption under the Securities Act, may
be sold other than pursuant to this Prospectus.

The  Selling  Stockholders  and any such  underwriters,  dealers or agents  that
participate in the  distribution of Securities may be deemed to be underwriters,
and  any  profit  on the  sale of the  Securities  by  them  and any  discounts,
commissions  or  concessions  received by them may be deemed to be  underwriting
discounts and commissions under the Securities Act. Brokers or dealers acting in
connection  with the sale of the Securities  contemplated by this Prospectus may
receive commissions in connection therewith.

At the time a particular offer of Securities is made, to the extent required,  a
supplement  to this  Prospectus  will be  distributed  which will  identify  the
Selling Stockholders,  identify and set forth the aggregate amount of Securities
being offered and the terms of the offering,  including the name or names of any
underwriters,  dealers or agents, the purchase price paid by any underwriter for
Securities  purchased from the Selling Stockholder,  any discounts,  commissions
and other items constituting  compensation from the Selling  Stockholder and any
discounts,  commissions or concessions allowed or re-allowed or paid to dealers,
including  the proposed  selling  price to the public.  Such  supplement to this
Prospectus and, if necessary,  a  post-effective  amendment to the  Registration
Statement of which the  Prospectus is a part,  will be filed with the Commission
to  reflect  the  disclosure  of  additional  information  with  respect  to the
distribution  of the  Securities.  The  Company  will  pay  all of the  expenses
incident to the registration and certain other expenses related to this offering
of the Securities,  other than  underwriting  commissions and discounts,  normal
commission expenses and brokerage fees, applicable transfer taxes and attorneys'
fees of Selling Stockholders' counsel.

The  Company  intends  to  require  the  Selling   Stockholders  to  enter  into
indemnification  agreements with the Company  pursuant to which the Company will
be  indemnified  against  failure  by the  Selling  Stockholders  to  deliver  a
Prospectus if required, as well as against certain civil liabilities,  including
liabilities under the Securities Act or the Exchange Act, incurred in connection
with any untrue (or alleged untrue)  statement of a material fact or omission of
a  material  fact in  this  Registration  Statement  pursuant  to an  applicable
Prospectus  Supplement  to the extent  such  liability  relates  to  information
supplied by the Selling Stockholder for inclusion in the Registration  Statement
pursuant to an applicable Prospectus Supplement.

In order to comply with certain  states'  securities  laws, if  applicable,  the
Securities  will be  sold  in such  jurisdictions  only  through  registered  or
licensed brokers or dealers.  In certain states,  the Securities may not be sold
unless the Securities  have been registered or qualified for sale in such state,
or unless an exemption from  registration or  qualification  is available and is
obtained.


                                  LEGAL MATTERS

The  validity of the  Securities  will be passed upon for the Company by Gardere

          (i)  To include any  prospectus  required  by section  10(a)(3) of the
               Securities Act of 1933;

          (ii) To reflect in the  prospectus  any facts or events  arising after
               the  effective  date of the  registration  statement (or the most
               recent post-effective  amendment thereof) which,  individually or
               in  the  aggregate,   represent  a  fundamental   change  in  the
               information   set   forth   in   the   registration    statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of  securities  offered (if the total dollar value of  securities
               offered  would not  exceed  that  which was  registered)  and any
               deviation  from  the low or  high  end of the  estimated  maximum
               offering  range may be reflected in the form of prospectus  filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the  changes  in volume  and price  represent  no more than a 20%
               change in the maximum  aggregate  offering price set forth in the
               "Calculation  of   Registration   Fee"  table  in  the  effective
               registration statement;

          (iii)To include any material  information  with respect to the plan of
               distribution   not  previously   disclosed  in  the  registration
               statement  or any  material  change  to such  information  in the
               registration statement.

          provided,  however, that paragraphs (1)(i) and (1)(ii) do not apply if
          the  registration  statement  is on  Form  S-3 or  Form  S-8,  and the
          information  required to be included in a post-effective  amendment by
          those  paragraphs  is  contained  in  periodic  reports  filed  by the
          registrant  pursuant to section 13 or section 15(d) of the  Securities
          Exchange  Act of  1934  that  are  incorporated  by  reference  in the
          registration statement.

     (2)  That,  for  the  purpose  of  determining   any  liability  under  the
          Securities Act of 1933,  each such  post-effective  amendment shall be
          deemed to be a new registration  statement  relating to the securities
          offered  therein,  and the  offering of such  securities  at that time
          shall be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of  the  securities  being  registered  which  remain  unsold  at  the
          termination of the offering.

The undersigned  registrant  hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the  registrant's
annual  report  pursuant  to Section  13(a) or Section  15(d) of the  Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Insofar as indemnification  for liabilities  arising under the Securities Act of
1933 may be permitted to  directors,  officers  and  controlling  persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrant has
been advised that in the opinion of the Securities and Exchange Commission, such
indemnification  is  against  public  policy  as  expressed  in the  Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Seitel, Inc.
50 Briar Hollow Lane, 7th Floor West
Houston, Texas 77027

Gentlemen:

     We have acted as counsel for Seitel,  Inc.  (the  "Company")  in connection
with  the   registration   statement   on  Form  S-8/S-3  of  the  Company  (the
"Registration  Statement"),  which is being filed on or about the date hereof by
the Company with the Securities and Exchange Commission under the Securities Act
of 1933,  as amended (the "Act"),  for the  registration  under the Act of up to
3,218,483  shares (the "S-8 Shares") of common stock,  par value $.01 per share,
of the Company to be issued by the Company upon  exercise of warrants  issued to
certain  employees of a  subsidiary  of the Company  prior to such  subsidiary's
initial public offering of its common stock (the "Departure Warrants").

     In the capacity as counsel for the Company, we have familiarized  ourselves
with the Certificate of Incorporation of the Company, as amended, and the Bylaws
of the Company,  as amended.  We have  examined all statutes and other  records,
instruments  and  documents  pertaining  to the  Company  that  we  have  deemed
necessary to examine for the purpose of this opinion.

     Based upon and subject to the foregoing,  we are of the opinion that,  upon
completion  of the  proceedings  being taken to permit such  transactions  to be
carried out in accordance  with the securities  laws of the various states where
required,  the S-8 Shares acquired in accordance with the terms of the Departure
Warrants will be validly issued, fully paid, and non-assessable.

     We are  members  of the Bar of the State of Texas and we do not  express an
opinion  herein  concerning  any other  law other  than the laws of the State of
Texas,  the  federal  law  of  the  United  States,  and  the  Delaware  General
Corporation Law.

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Registration  Statement  and to the  reference  to us under the  caption  "Legal
Matters" in the Prospectus forming a part thereof.

                                         Very truly yours,

                                         GARDERE WYNNE SEWELL & RIGGS, L.L.P.

                                  SEITEL, INC.

                    COMMON STOCK PURCHASE WARRANT CERTIFICATE
             TO PURCHASE Warrants_Exercisable SHARES OF COMMON STOCK

Certificate No. Warrant_Number

     This Warrant  Certificate  certifies that First Last,  Address,  CityState,
(SS# SSN) is the registered  holder  ("Holder") of  Warrants_Exercisable  Common
Stock  Purchase  Warrants (the  "Warrants")  to purchase  shares of the $.01 par
value common stock,  ("Common  Stock") of SEITEL,  INC., a Delaware  corporation
(the "Company").  Subject to Section 11 hereof,  each Warrant enables the Holder
to purchase from the Company at any time until 5:00 p.m., Houston,  Texas, local
time on the  earlier  of (i)  three  months  after  the  Holder  ceases to be an
employee,   officer,  or  director  of  Eagle  Geophysical,   Inc.,  a  Delaware
corporation  ("Eagle")  and any  subsidiary  of Eagle for any reason  other than
death or  disability  (within  the meaning of Section  22(e)(3) of the  Internal
Revenue Code of 1986, as amended (the  "Code")),  (ii) one year after the Holder
ceases to be an employee,  officer, or director of Eagle due to his or her death
or  disability,  and (iii)  Expiration_Date,  one fully paid and  non-assessable
share of Common Stock ("Share") upon  presentation and surrender of this Warrant
Certificate  and upon  payment of the  Purchase  Price per Share  determined  in
accordance  with the terms hereof.  Payment shall be made in lawful money of the
United  States of  America by  certified  check  payable  to the  Company at its
principal office at 50 Briar Hollow Lane, 7th Floor West, Houston,  Texas 77027.
As hereinafter  provided,  the Purchase  Price and number of Shares  purchasable
upon the exercise of the Warrants are subject to modification or adjustment upon
the happening of certain events.

     THIS WARRANT IS NOT ASSIGNABLE OR TRANSFERABLE BY THE HOLDER EXCEPT BY WILL
OR THE LAWS OF DESCENT AND DISTRIBUTION UPON THE HOLDER'S DEATH.

     1.   Upon  surrender  to  the  Company,  this  Warrant  Certificate  may be
          exchanged  for another  Warrant  Certificate  or Warrant  Certificates
          evidencing  a like  aggregate  number  of  Warrants.  If this  Warrant
          Certificate  shall be exercised in part,  the Holder shall be entitled
          to receive  upon  surrender  hereof  another  Warrant  Certificate  or
          Warrant Certificates  evidencing the number of Warrants not exercised.
          During the lifetime of the Holder,  the Warrants may be exercised only
          by the  Holder.  If the  Holder  dies or becomes  disabled  within the
          meaning of Section  22(e)(3) of the Code prior to the termination date
          specified  herein  without having  exercised all of the Warrants,  the
          remaining  Warrants  may be  exercised  to the extent the Holder could
          have  exercised the Warrants on the date of his death or disability at
          any time prior to the expiration  hereof by (i) the Holder's estate or
          a person who acquired the right to exercise the Warrants by bequest or
          inheritance  or by reason  of the death of the  Holder in the event of
          the Holder's death, or (ii) the Holder or his personal  representative
          in the event of the Holder's disability, subject to the other terms of
          this Warrant  Certificate and applicable  laws, rules and regulations.
          For purposes of this Warrant Certificate,  the Company shall determine
          the date of disability of the Holder.

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

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

          (a)  This Warrant  Certificate  is  exercisable in whole or in part by
               the Holder in person or by attorney duly authorized in writing at
               the principal office of the Company.

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

          (c)  Anything  herein  to the  contrary  notwithstanding,  in no event
               shall the  Company be  obligated  to issue  Warrant  Certificates
               evidencing  other  than a  whole  number  of  Warrants  or  issue
               certificates  evidencing other than a whole number of Shares upon
               the exercise of this Warrant Certificate; provided, however, that
               the  Company  shall pay with  respect to any such  fraction  of a
               Share an amount of cash  based  upon the  current  public  market
               value (or book value,  if there shall be no public  market value)
               for Shares purchasable upon exercise hereof. For purposes of this
               Paragraph  3(c),  the current  public  market value of a share of
               Common  Stock on any date shall be deemed to be the  arithmetical
               average  of the  following  prices  for such of the  thirty  (30)
               business  days  immediately   preceding  such  day  as  shall  be
               available:  (i) for any of such  days on which the  Common  Stock
               shall be listed on a national securities exchange,  the last sale
               price on such day or,  if there  shall  have been no sale on such
               day,  the  average of the  closing  bid and asked  prices on such
               exchange  on such day,  or (ii) for any of such days on which the
               Common  Stock  shall  not  be  listed  on a  national  securities
               exchange  but shall be included in the  National  Association  of
               Securities  Dealers Automated  Quotation System  ("NASDAQ"),  the
               average of the closing bid and asked prices on such day quoted by
               brokers and dealers  making a market in NASDAQ,  furnished by any
               member of the New York Stock Exchange selected by the Company for
               that  purpose,  or (iii) for any of such days on which the Common
               Stock shall not be so listed on a national securities exchange or
               included in NASDAQ but shall be quoted by three brokers regularly
               making a market in such  shares in the  over-the-counter  market,
               the  average  of the  closing  bid and asked  prices on such day,
               furnished by any member of the New York Stock  Exchange  selected
               by the  Company for that  purpose,  or (iv) for any days on which
               the  information  described in items (i),  (ii) or (iii) above is
               unavailable,  the book  value  per share of the  Common  Stock as
               determined  in  accordance  with  generally  accepted  accounting
               principles;  provided,  however,  in its  discretion the board of
               Directors of the Company may make an appropriate reduction in the
               "current  public market value" based upon any applicable  trading
               restrictions to particular shares of Common Stock.

     4.   The Purchase  Price per Share for the  Warrants  shall be equal to the
          following:

          (a)  In the event the Holder exercises the  lc_option_warrant  granted
               to the Holder by the  Company on  OriginalGrant_Date  to purchase
               Warrants_Exercisable  shares of Common Stock at an exercise price
               of $OriginalPriceShare per share (the "Original  Option_Warrant")
               in full on a single  date,  the  Purchase  Price for the Warrants
               shall equal the closing  price of a Share of Common  Stock on the
               date of exercise in full of the Original Option_Warrant.

          (b)  In the event the Original Option_Warrant is exercised in full but
               in several  installments on different  dates,  the Purchase Price
               for the  number  of  Warrants  equal to the  number  of shares of
               Common Stock  acquired  upon each such  exercise  shall equal the
               closing price of a Share of Common Stock on the date of each such
               exercise of the Original Option_Warrant.

          (c)  In the event the Original Option Warrant is partially  exercised,
               the Purchase Price for the number of Warrants equal to the number
               of shares of Common Stock  acquired upon each such exercise shall
               equal the closing price of a Share of Common Stock on the date of
               each  such  exercise  of the  Original  Option_Warrant,  and  the
               Purchase   Price  for  the  number  of  Warrants   equal  to  the
               unexercised  portion of the Original  Option_Warrant  shall equal
               the greater of (i)  $OriginalPriceShare or (ii) the closing price
               of a Share of Common Stock on November 8, 1997.

          (d)  In  the  event  the  Holder  does  not   exercise   the  Original
               Option_Warrant,  the Purchase  Price for the Warrants shall equal
               the greater of (i)  $OriginalPriceShare or (ii) the closing price
               of a Share of Common Stock on November 8, 1997.

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

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

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

     8.   The  number  of  shares  of  Common  Stock  covered  by  this  Warrant
          Certificate,  and the Purchase Price thereof, shall be subject to such
          adjustment  as the Board of  Directors  of the Company  acting in good
          faith deems  appropriate to reflect any stock  dividend,  stock split,
          share  combination,  exchange  of  shares,  recapitalization,  merger,
          consolidation, separation, reorganization, liquidation or the like, of
          or by the  Company.  In the event the Company  shall be a party to any
          merger,  consolidation or corporate  reorganization,  as the result of
          which the Company shall be the surviving  corporation,  the rights and
          duties of the  Holder and the  Company  shall not be  affected  in any
          manner.  In the event the Company shall sell all or substantially  all
          of its  assets  or shall be a party to any  merger,  consolidation  or
          corporate reorganization, as the result of which the Company shall not
          be the  surviving  corporation,  or in the event  any other  person or
          entity may make a tender or  exchange  offer for stock of the  Company
          (the surviving corporation,  purchaser, or tendering corporation being
          collectively referred to as the "Purchaser", and the transaction being
          collectively referred to as the "Purchase"),  then the Company may, at
          its  election,  (a) reach an  agreement  with the  Purchaser  that the
          Purchaser  will  assume  the  obligations  of the  Company  under this
          Warrant  Certificate;  (b) reach an agreement  with the Purchaser that
          the Purchaser  will convert the Warrants  represented  by this Warrant
          Certificate  into  warrants of at least equal value as to stock of the
          Purchaser;  or (c) not  later  than  thirty  (30)  days  prior  to the
          effective  date of the  Purchase,  notify the Holder that his Warrants
          are  accelerated  and  afford to the  Holder a right for ten (10) days
          after the date of such notice to exercise any then unexercised portion
          of the Warrants  whether or not the Warrants shall then be exercisable
          under the  terms of this  Warrant  Certificate.  Within  such  ten-day
          period,  the Holder may exercise any portion of the Warrants as he may
          desire and deposit with the Company the requisite  cash to purchase in
          full and not in installments  the Common Stock thereby  exercised,  in
          which  case the  Company  shall,  prior to the  effective  date of the
          Purchase,  issue all  Common  Stock  thus  exercised,  which  shall be
          treated as issued stock for purposes of the Purchase.

     9.   The  Warrants  may not be exercised in whole or in part and no cash or
          certificates  representing  Shares shall be delivered if any requisite
          approval  or consent of any  government  authority  of any kind having
          jurisdiction  over  the  exercise  of the  Warrants  or of  any  stock
          exchange  on which  the  Common  Stock is  listed  shall not have been
          secured or if such  exercise of delivery  would cause any violation of
          any applicable  laws,  regulations or stock exchange rules,  including
          but not limited to applicable  Federal and State  securities laws. The
          Holder of this Warrant  Certificate,  each permitted transferee hereof
          and  any  holder  and  transferee  of any  Shares,  by his  acceptance
          thereof,  agrees that (i) no public distribution of Warrants or Shares
          will be made in violation of the  Securities  Act of 1933,  as amended
          (the  "Act"),  and  (ii)  during  such  period  as the  delivery  of a
          prospectus  with  respect to Warrants or Shares may be required by the
          Act,  no public  distribution  of Warrants or Shares will be made in a
          manner or on terms  different  from  those  set  forth in, or  without

<PAGE>

          delivery of, a prospectus then meeting the  requirements of Section 10
          of the Act and in  compliance  with all  applicable  state  securities
          laws.  The  Holder  of this  Warrant  Certificate  and each  permitted
          transferee  hereof further agrees that if any  distribution  of any of
          the Warrants or Shares is proposed to be made by them  otherwise  than
          by delivery of a prospectus  meeting the requirements of Section 10 of
          the Act,  such  action  shall be taken  only after  submission  to the
          Company of an opinion of counsel,  reasonably satisfactory in form and
          substance to the  Company's  counsel,  to the effect that the proposed
          distribution  will  not be in  violation  of the Act or of  applicable
          state law. Furthermore, it shall be a condition to the transfer of the
          Warrants that any permitted  transferee thereof deliver to the Company
          his written  agreement  to accept and be bound by all of the terms and
          conditions in this Warrant Certificate.

     10.  This Warrant  Certificate  is intended to be an Employee  Benefit Plan
          within the meaning of Rule 405 under the Securities Act.


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

          (a)  As of the date  hereof  and  prior to  3/20/99,  up to a total of
               one-third  of  the  total  Warrants  represented  hereby  may  be
               exercised.

          (b)  After  3/20/99 and prior to 3/20/00,  up to a total of two-thirds
               of  the  total  Warrants  represented  hereby  may  be  exercised
               (including the Warrants previously exercisable hereunder).

          (c)  After 3/20/00,  all of the total Warrants  represented hereby may
               be exercised.

     If pursuant to the  foregoing  the Holder would be allowed to exercise with
     respect to a fractional  Warrant,  such  installment will be rounded off to
     the next highest  whole  number of  Warrants.  In the event of the Holder's
     termination  of employment and  directorship  with Eagle for whatever cause
     (including  death or disability),  the Warrants will be exercisable only to
     the extent that the Holder could have  exercised  such Warrants on the date
     of his termination of employment or directorship.]

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

     1.   Upon  surrender  to  the  Company,  this  Warrant  Certificate  may be
          exchanged  for another  Warrant  Certificate  or Warrant  Certificates
          evidencing  a like  aggregate  number  of  Warrants.  If this  Warrant

          to receive  upon  surrender  hereof  another  Warrant  Certificate  or
          Warrant Certificates evidencing the number of Warrants not exercised.

          directors or upon any matter  submitted to shareholders at any meeting
          thereof  or to  give  or  withhold  consent  to any  corporate  action

          conveyance,  or  otherwise)  or to receive  notice of  meetings  or to
          receive dividends or subscription  rights or otherwise until a Warrant
          shall have been  exercised and the Common Stock  purchasable  upon the
          exercise thereof shall have become issuable.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     11.  In the case:

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

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

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

          D.   Of   the   proposed   voluntary   or   involuntary   dissolution,
               liquidation, or winding up of the Company; or

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     WITNESS the following signatures as of FULL_GRANT_DATE.

     This Warrant  Certificate  certifies that Russell Hoffman is the registered
holder  ("Holder") of 81,103 Common Stock Purchase  Warrants (the "Warrants") to
purchase shares of the $.01 par value common stock,  ("Common Stock") of SEITEL,
INC., a Delaware corporation (the "Company"). Subject to Section 15 hereof, each
Warrant  enables  the Holder to purchase  from the  Company at any time,  on and
after 4/23/98 and until 5:00 p.m.,  Houston,  Texas, local time on 4/23/08,  one
fully paid and non-assessable  share of Common Stock ("Share") upon presentation
and surrender of this Warrant Certificate and upon payment of the purchase price
of $15.875 per Share. Payment shall be made in lawful money of the United States
of America by certified check payable to the Company at its principal  office at
50 Briar Hollow Lane,  West, 7th Floor,  Houston,  Texas,  77027. As hereinafter
provided,  the purchase price and number of Shares purchasable upon the exercise
of the Warrants are subject to  modification or adjustment upon the happening of
certain events.

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

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

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

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

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

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

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

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

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

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

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

     8.   As used  herein,  the term  "Exercise  Rate" shall mean the number and
          kind of shares of  capital  stock of the  Company  which the Holder of
          this Warrant  shall be entitled  from time to time to receive for each
          $1,000.00 of warrant exercise payment.  Unless and until an adjustment
          thereof shall be required as hereinafter  provided,  the Exercise Rate
          shall be 62.992 shares of Common Stock.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     11.  In the case:

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

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

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

          D.   Of   the   proposed   voluntary   or   involuntary   dissolution,
               liquidation, or winding up of the Company; or

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

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

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

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

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

          A.   If the  Holder  ceases to be an  employee  at the  Company  (or a
               subsidiary  of the Company) for any reason other than by death or
               disability,  this Warrant Certificate may be exercised by Holder,
               to the extent that it was exercisable at the date of termination,
               at any time within three  months after the date Holder  ceases to
               be an employee,  but not later than 4/23/08  except that, in case
               of his death or disability within that three-month  period,  this
               Warrant  Certificate may be exercised as provided in subparagraph
               (b) below.

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

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

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

               at any time within one year after the date of  Holder's  death or
               disability, but not later than 4/23/08.

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

                             SHARES OF COMMON STOCK

     This Warrant  Certificate  certifies that Russell Hoffman is the registered
holder  ("Holder") of 150,000 Common Stock Purchase Warrants (the "Warrants") to
purchase shares of the $.01 par value common stock,  ("Common Stock") of SEITEL,
INC., a Delaware corporation (the "Company"). Subject to Section 15 hereof, each
Warrant  enables  the Holder to purchase  from the  Company at any time,  on and
after 4/23/98 and until 5:00 p.m.,  Houston,  Texas, local time on 4/23/08,  one
fully paid and non-assessable  share of Common Stock ("Share") upon presentation
and  surrender  of this  Warrant  Certificate  and upon  payment of the purchase
price.  Payment shall be made in lawful money of the United States of America by
certified  check  payable  to the  Company at its  principal  office at 50 Briar
Hollow Lane, West, 7th Floor,  Houston,  Texas, 77027. As hereinafter  provided,
the  purchase  price and number of Shares  purchasable  upon the exercise of the
Warrants are subject to modification or adjustment upon the happening of certain
events.

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

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

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

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

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

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

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

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

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

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

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

     8.   As used  herein,  the term  "Exercise  Rate" shall mean the number and
          kind of shares of  capital  stock of the  Company  which the Holder of
          this Warrant  shall be entitled  from time to time to receive for each
          $1,000.00 of warrant exercise payment.  Unless and until an adjustment
          thereof shall be required as hereinafter  provided,  the Exercise Rate
          shall be determined in accordance with Section 15 hereof.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

          I.   For  purposes of this  Paragraph  10, the current  public  market
               value of a share of Common  Stock on any date  shall be deemed to
               be the  arithmetical  average of the following prices for such of
               the thirty (30) business days  immediately  preceding such day as
               shall be  available:  (i) for any of the such  days on which  the
               Common Stock shall be listed on a national  securities  exchange,
               the last sale  price on such day or, if there  shall have been no
               sale on such day, the average of the closing bid and asked prices
               on such  exchange  on such  day,  or (ii) for any of such days on
               which  the  Common  Stock  shall  not  be  listed  on a  national
               securities  exchange  but  shall  be  included  in  the  National
               Association  of Securities  Dealers  Automated  Quotation  System
               ("NASDAQ"),  the average of the  closing bid and asked  prices on
               such day quoted by brokers and dealers making a market in NASDAQ,

<PAGE>

               furnished by any member of the New York Stock  Exchange  selected
               by the Company for that purpose, or (iii) for any of such days on
               which the  Common  Stock  shall  not be so  listed on a  national
               securities  exchange or included in NASDAQ but shall be quoted by
               three  brokers  regularly  making a market in such  shares in the
               over-the-counter market, the average of the closing bid and asked
               prices on such day, furnished by any member of the New York Stock
               Exchange  selected by the Company for that  purpose,  or (iv) for
               any days on which the information described in items (i), (ii) or
               (iii)  above is  unavailable,  the book  value  per  share of the
               Common Stock as determined in accordance with generally  accepted
               accounting principles;  provided,  however, in its discretion the
               Board may make an  appropriate  reduction in the "current  public
               market value" based upon any applicable  trading  restrictions to
               particular shares of Common Stock.

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

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

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

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

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

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

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

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

     11.  In the case:

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

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

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

          D.   Of   the   proposed   voluntary   or   involuntary   dissolution,
               liquidation, or winding up of the Company; or

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

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

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

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

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

          A.   If the  Holder  ceases to be an  employee  at the  Company  (or a
               subsidiary  of the Company) for any reason other than by death or
               disability,  this Warrant Certificate may be exercised by Holder,
               to the extent that it was exercisable at the date of termination,
               at any time within three  months after the date Holder  ceases to
               be an employee,  but not later than 4/23/08  except that, in case
               of his death or disability within that three-month  period,  this
               Warrant  Certificate may be exercised as provided in subparagraph
               (b) below.

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

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

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

               at any time within one year after the date of  Holder's  death or
               disability, but not later than 4/23/08.

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

<PAGE>

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

          A.   50,000 of the Warrants shall become  exercisable upon an increase
               in the price to earnings  multiple of Seitel,  Inc.  common stock
               (the "p/e  multiple")  of 5.0 or more over the base  multiple  of
               15.119.

          B.   An  additional  50,000 of the Warrants  shall become  exercisable
               upon an  increase  in the p/e  multiple  of 10.0 or more over the
               base multiple of 15.119.

          C.   An  additional  50,000 of the Warrants  shall become  exercisable
               upon an  increase  in the p/e  multiple  of 15.0 or more over the
               base multiple of 15.119.

          Such vesting  will be effective as of January 2 of the year  following
          the year to which such multiple increase relates ("Vesting Date").

          The  purchase  price of the vesting  Warrants  shall equal the closing
          price of the Company's Common Stock on the Vesting Date.

          At the end of each year,  the closing price per share of Seitel,  Inc.
          common  stock for the last ten trading  days of each  quarter  will be
          averaged (2nd,  3rd and 4th quarters only for 1998),  and that average
          price  will be  divided by the  year's  earnings  per share  (diluted)
