         installments (the "Base Salary").

                           (b)  Bonus  in  Lieu of  Pre-Tax  Profits  Bonus.  In
         consideration  of  Employee's   agreement  to  the  amendments  to  the

         Agreement,  the  Company  shall pay  Employee a bonus in the  aggregate

                           (i) The Company shall issue  Employee  125,000 shares
                  of restricted  common stock of the Company on the date hereof,
                  which  shall be valued at  $6.5875  per  share,  or a total of

                  transfer restrictions  applicable to such shares of restricted
                  stock),  and shall pay to  Employee on the date hereof the sum

                  2002 the sum of $615,385,  subject to withholding as specified

                           (vi) The payments in paragraphs (i) through (v) above
                  shall be contingent  on Employee  continuing to be an employee
                  of the  Company  on the date such  payments  are due,  and the
                  right to  receive  such  payments  shall not vest  until  such
                  dates; provided,  however, that if Employee is not an employee
                  of the  Company  on any such  date due to  termination  of his
                  employment  prior  to such  date as a result  of his  death or
                  disability,  the Company shall  continue to make such payments
                  to Employee or his estate on such dates.

                           (vii) The  payments  in  paragraphs  (i)  through (v)
                  above shall be subject to federal and state tax withholding at
                  the aggregate rate of 35%  (comprised of the minimum  required
                  for  federal   income  tax,   Medicare  and  Social   Security
                  withholding, and any balance of the 35% being withheld for New
                  York State  income  tax and  Connecticut  State  income tax as
                  directed by Employee). For the purpose of paragraph (a) above,
                  the  withholding  shall  be based  on the  amount  of the cash
                  payment and the $823,438 value  attributed to the stock issued
                  to Employee.

                           (c) Salary  Continuation  Benefits.  The Company will
         pay, so long as the Employee's Employment Agreement,  as amended, is in
         full  force and  effect  on the date of his  death,  a  monthly  salary
         continuation  amount  to the  Employee's  estate or his  designee,  for
         twelve  months  beginning on the date of his death.  The annual  salary
         continuation  amount will equal the Employee's  base salary at his date
         of death."

is hereby  amended by deleting the existing  paragraph (a) and replacing it with

         Chairman of the Board and the Chief  Executive  Officer of the Company.
         His duties shall be to advise and counsel the Chairman of the Board and
         the Chief Executive  Officer  regarding such matters as the Chairman of
         the Board or the Chief  Executive  Officer may request,  and to perform
         such other duties as the  Chairman of the Board or the Chief  Executive
         Officer may reasonably request,  such as (but not limited to) analyzing
         financing   proposals,   analyzing  market  data,   analyzing  proposed
         acquisitions,   analyzing  business  plans,  and  investor   relations.
         Employee shall not be required to relocate his residence to perform his
         duties under this Agreement."

         5.   Fringe  Benefits.  Section 9 of the Employment Agreement is hereby
amended by deleting the existing Section 9 and replacing it with the following:

                  "9.  Fringe  Benefits.  The  Employee  shall  be  entitled  to
         participate  on the same bases,  except where stated  otherwise in this
         Agreement, and subject to the same qualifications as other employees of
         the Employer, in any pension, profit sharing, stock purchase,  savings,
         hospitalization,  sick leave and other fringe  benefit  plans in effect
         from time to time with respect to  employees  of Employer  (the "Fringe
         Benefits").  Employer  agrees  that each of the Fringe  Benefits of the
         Employer  in  effect  on the date  hereof,  or at any time  during  the
         Employment  Period  shall not be  terminated  or modified in any manner
         which reduces the benefits of the Employee  without first obtaining the
         written consent of the Employee.

         6.   Termination.  Paragraph  (b)  of  Section  13  of  the  Employment
Agreement is hereby amended by deleting the existing paragraph (b) and replacing
it with the following:

                  A(b)  Termination for Employer's  Breach:  Employee shall have
         the  right to  terminate  this  Agreement  if the  Employer  materially
         breaches  any of the  provisions  hereof  and such  breach is not cured
         within thirty (30) days after the Employer receives written notice from
         Employee  thereof.  In  such  event,  or in  the  event  of a  wrongful
         termination of Employee, all monies due to Employee through the term of
         this  Agreement,  including  the  Severance  Payment,  shall be paid by
         Employer in a lump sum amount  within  thirty  (30) days of  Employee's
         termination.  Employee shall have no obligation to mitigate his loss or

         services to receive such payments.

         7.   Restriction on Transfer of Stock,  Registration  Rights.  Employee

Company an  express  contractual  right of offset  against  payments  due by the
Company to Employee  hereunder,  and the Company shall withhold from the amounts
payable to  Employee  hereunder  the  amounts of such loan  payments  (including
interest).

         negotiate substitute  provisions for those rendered or declared illegal
         or unenforceable,  but all remaining provisions of this Agreement shall
         remain  in full  force  and  effect.  If the  payment  of the  Bonus to
         Employee  under  Section  3(b) of the  Employment  Agreement as amended
         hereby is successfully  challenged by the Company, any person acting on
         behalf  of the  Company,  or any  third  party  and the  effect of such
         challenge  is that  Employee  is  required to return the amount of such
         Bonus to the Company,  then the bonus  provisions  under Paragraphs (b)
         and (c) of Section 3 of the Employment  Agreement as in effect prior to

Mr. David Lawi
3 Ramapo Trail
Harrison, New York 10528

     Re:  Promissory  Note  dated  October  2,  1998 in the  original  amount of
          $773,437.50

Dear Mr. Lawi,

     On the date hereof,  the Company has entered into an  Employment  Agreement
Amendment  No. 2 (the  "Employment  Agreement  Amendment")  with you pursuant to
which we have agreed to change the payment terms of that certain promissory note
(the "Note") dated October 2, 1998 in the original amount of $773,437.50 made by
you payable to the order of Seitel,  Inc.  (the  "Company") as set forth herein.
Also pursuant to the Employment Agreement  Amendment,  we have agreed to release
the  existing  security  for the Note  (75,000  shares  of  common  stock of the
Company) and to take in exchange for such security a contractual right of setoff
as described in Section 8 of the Employment Agreement Amendment.  As of the date
hereof, the balance due on the Note was $665,778  (including interest accrued to
such date).  This letter will serve as the formal amendment of the payment terms
of the Note and the release of such pledged stock as security for the Note.
