               Statement of Amendments Effective November 29, 1995

     amended to read in its entirety as follows:

          (7) Options shall mean the Incentive Stock Options and the
     Non-Qualified Stock Options granted from time to time under the Plan. If
     Options are not designated as Incentive Stock Options or Non-Qualified

     Non-Qualified Stock Options.

2.   The following new definitions are hereby added to Section II:

          (10) Incentive Stock Option shall mean a stock option granted under

     the date the Incentive Stock Option is granted. However, the purchase price
     of each Share placed under an Incentive Stock Option to a Participant who
     owns stock possessing more than ten percent (10%) of the total combined
     voting power of all classes of stock of the Company or any Subsidiary at
     the time of the grant shall be at least one hundred and ten percent (110%)
     of the Fair Market Value of such Share on the date the Option is granted.
     The purchase price of each Share placed under a Non-Qualified Stock Option

     Non-Qualified Stock Option is granted.

4.   The first two sentences of the subsection of Section VII headed "Option
     Period and Terms" are hereby amended to read in their entirety as follows:

          No option shall be exercisable after the expiration of ten (10) years

     an Incentive Stock Option is granted owns stock possessing more than ten
     percent (10%) of the total combined voting power of all classes of stock of
     the Company or any Subsidiary at the time such Incentive Stock Option shall
     not be exercisable after the expiration of five (5) years from the date
     such Incentive Stock option is granted.

5.   The subsection of Section VII headed "Maximum Annual Amount Per Employee"
     is hereby amended to read in its entirety as follows:

<PAGE>

          The aggregate fair market value (determined as of the time the
     Incentive Stock Option is granted) of the stock with respect to which
     Incentive Stock Options are exercisable for the first time by any
     Participant during any calendar year (under this and any other plans of the
     Company or any Subsidiary) shall not exceed $100,000.<PAGE>

                                                                    EXHIBTI 10.4

                  SEITEL, INC. 1993 INCENTIVE STOCK OPTION PLAN
                Statement of Amendments Effective April 22, 1996

1.   The first sentence of Section V is hereby amended to read as follows:

                           Effective December 31, 1996

The section of the Plan headed "Nonassignability of Options" in Article IX is
hereby deleted and replaced with the following:

Limited Transferability of Options

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

                                                                    EXHIBIT 10.8

                                  SEITEL, INC.
                    NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

1.   Purpose. The purpose of this Non-Employee Directors' Stock Option Plan
     (the "Plan) of Seitel, Inc. (the "Company") is to promote ownership by
     non-employee Directors of a greater proprietary interest in the Company,
     thereby aligning such Directors' interests more closely with the interests
     of stockholders of the Company, and to assist the Company in attracting and
     retaining qualified persons to serve as non-employee Directors.

2.   Definitions. In addition to terms defined elsewhere in the Plan, the
     following are defined terms under the Plan:

     (a) "Code" means the Internal Revenue Code of 1986, as amended. References
     to any provision of the Code include regulations thereunder and successor
     provisions and regulations.

     (b) "Exchange Act" means the Securities Exchange Act of 1934, as amended.
     References to any provision of the Exchange Act include rules thereunder
     and successor provisions and rules.

     (c) "Fair Market Value" of Stock means the closing price of the Stock on
     the date on which such value is to be determined, as reported for such day
     by the New York Stock Exchange.

     (d) "Option" means the right, granted to a Participant under Section 6, to
     purchase Stock at the specified exercise price for a specified period of
     time under the Plan.

     (e) "Participant" means a Director who is eligible to receive and is
     granted Options under the Plan.

     (f) "Stock" means the Common Stock, $.01 par value, of the Company and such
     other securities as may be substituted for Stock or such other securities
     pursuant to Section 7.

3.   Shares Available Under the Plan. The total number of shares of Stock
     reserved and available for delivery under the Plan is 75,000, subject to
     adjustment as provided in Section 7 below. Such shares may be authorized
     but unissued shares or treasury shares. If any Option expires or terminates
     for any reason without having been exercised in full, the shares remaining
     subject to such Option will again be available for delivery under the Plan.

4.   Administration of the Plan. The Plan will be administered by the Board of
     Directors of the Company, provided that any action by the Board of
     Directors relating to the Plan will be taken only if, in addition to any
     other required vote, approved by the affirmative vote of the majority of
     the Directors who are not then eligible to participate under the Plan.

5.   Eligibility. Each Director of the Company who, on any date on which an
     Option is to be granted hereunder, is not, and has not been during the
     preceding three months, an employee of the Company or any parent or
     subsidiary of the Company will be eligible to receive a grant of an Option
     at such date. No person other than those specified in this Section 5 will
     participate in the Plan.

6.   Stock Options. An option to purchase 5,000 shares of Stock will be granted
     under the Plan to each person who is an existing non-employee Director of
     the Company on the effective date of the Plan. Additionally, an option to
     purchase 5,000 shares of Stock will be granted under the Plan to each
     person who, after the effective date of the Plan, is first elected or
     appointed to serve as a Director of the Company, such grant to be effective
     at the date of such first election or appointment, if such Director is then
     eligible to receive an Option grant. Also, an Option to purchase 1 ,000
     shares of Stock will be granted each year to each

                                       A-1

<PAGE>

     Director of the Company who is then eligible to receive an Option grant at
     the close of business on the day of the Company's annual meeting of
     stockholders at which Directors (or a class of Directors if the Company
     then has a classified Board of Directors) are elected or reelected by the
     Company's stockholders. The foregoing notwithstanding, no Director may be
     granted an Option more than once during any one calendar year under the
     Plan. Options granted under the Plan will be non-qualified stock options
     which will be subject to the following terms and conditions:

     (a) Exercise Price. The exercise price per share of Stock purchasable under
     an Option will be equal to 100% of the Fair Market Value of Stock on the
     date of grant of the Option.

     (b) Option Term. Each Option will expire at the earlier of (i) five years
     after the date of grant, (ii) twelve months after the Participant ceases to
     serve as a Director of the Company due to death, disability, or retirement
     at or after age 65, or (iii) sixty days after the Participant ceases to
     serve as a Director of the Company for any reason other than death,
     disability, or retirement at or after age 65.

     (c) Exercisability. Each Option will become fully exercisable beginning one
     year after the date of grant, and will thereafter remain exercisable until
     the Option expires; provided, however, that an Option previously granted to
     a Participant will be exercisable after the Participant ceases to serve as
     a Director of the Company for any reason other than death, disability, or
     retirement at or after age 65 only if the Option was exercisable at the
     date of such cessation of service.

     (d) Method of Exercise. Each Option may be exercised, in whole or in part,
     at such time as it is exercisable and prior to its expiration by giving
     written notice of exercise to the Company specifying the Option to be
     exercised and the number of shares to be purchased, and accompanied by
     payment in full of the exercise price in cash (including by check) or by
     surrender of shares of Stock of the Company acquired by the Participant at
     least six months prior to the exercise date and having a Fair Market Value
     at the time of exercise equal to the exercise price, or a combination of a
     cash payment and surrender of such Stock.

7.   Adjustment Provisions. In the event any recapitalization, reorganization,
     merger, consolidation, spin-off, combination, repurchase, exchange of
     shares or other securities of the Company, stock split or reverse split,
     extraordinary dividend having a value in excess of 150% of the quarterly
     dividends paid during the preceding twelve-month period, liquidation,
     dissolution, or other similar corporate transaction or event affects Stock
     such that an adjustment is determined by the Board of Directors to be
     appropriate in order to prevent dilution or enlargement of Participants'
     rights under the Plan, then the Board of Directors will, in a manner that
     is proportionate to the change to the Stock and is otherwise equitable,
     adjust (i) any or all of the number or kind of shares of Stock reserved for
     issuance and delivery under the Plan, (ii) the number or kind of shares of
     Stock to be subject to each automatic grant of Options under Section 6, and
     (iii) the number and kind of shares of Stock issuable or deliverable upon
     exercise of outstanding Options, and/or the exercise price per share
     thereof (provided that no fractional shares will be issued upon exercise of
     any Option). The foregoing notwithstanding, no adjustment may be made
     hereunder except as shall be necessary to preserve, without exceeding, the
     value of outstanding Options and potential grants of Options. If at any
     date an insufficient number of shares are available for the automatic grant
     of Options at that date, Options will be automatically granted under
     Section 6 proportionately to Participants to the extent shares are
     available.

8.   Changes to the Plan. The Board of Directors may amend, alter, suspend,
     discontinue, or terminate the Plan or authority to grant Options under the
     Plan without the consent of stockholders or Participants, except that any
     such action will be subject to the approval of the Company's stockholders
     at the next annual meeting of stockholders having a record date after the
     date such action was taken if such stockholder approval is required by any
     federal or state law or regulation or the rules of any automated quotation
     system or stock exchange on which the Stock may then be quoted or listed,
     or if the Board of Directors determines in its discretion to seek such
     stockholder approval; provided, however, that, without the consent of an
     affected Participant, no such action may materially impair the rights of
     such Participant with respect to any previously granted Option; and
     provided further, that any Plan provision that specifies the

                                       A-2

<PAGE>

     Directors who may receive grants of Options, the amount and price of
     securities to be granted to such Directors, and the timing of grants to
     such Directors, or is otherwise a "plan provision" referred to in Rule
     16b-3(c)(2)(ii)(B) under the Exchange Act, shall not be amended more than
     once every six months, other than to comport with changes in the Code or
     the rules thereunder.

9.   General Provisions.

     (a) Consideration for Grants; Agreements. Options will be granted under the
     Plan in consideration of the services of the Participants and, except for
     the payment of the Option exercise price upon exercise of the options, no
     other consideration shall be required therefor. Grants of Options will be
     evidenced by agreements executed by the Company and the Participant
     containing the terms and conditions set forth in the Plan together with
     such other terms and conditions not inconsistent with the Plan as the Board
     of Directors may from time to time approve.

     (b) Compliance with Laws and Obligations. The Company will not be obligated
     to issue or deliver Stock in connection with any Option in a transaction
     subject to the registration requirements of the Securities Act of 1933, as
     amended, or any state securities law, any requirement under any listing
     agreement between the Company and any automated quotation system or
     national securities exchange, or any other law, regulation or contractual
     obligation, until the Company is satisfied that such laws, regulations, and
     other obligations of the Company have been complied with in full.
     Certificates representing shares of Stock delivered under the Pan will be
     subject to such stop-transfer orders and other restrictions as may be
     applicable under such laws, regulations, and other obligations of the
     Company, including any requirement that a legend or legends be placed
     thereon.

     (c) Non-transferability. Options and any other right under the Plan that
     may constitute a "derivative security" as generally defined in Rule
     16a-1(c) under the Exchange Act will not be transferable by a Participant
     except by will or the laws of descent and distribution (or to a designated
     beneficiary in the event of a Participant's death), and will be exercisable
     during the lifetime of a Participant only by such Participant or his or her
     guardian or legal representative.

     (d) Compliance with Rule 16b-3. It is the intent of the Company that this
     Plan comply in all respects with applicable provisions of Rule 16b-3 under
     the Exchange Act in connection with any grant of Options to a Participant.
     Accordingly, if any provision of this Plan or any agreement hereunder does
     not comply with the requirements of Rule 16b-3 as then applicable to any
     such grant to a Participant, or would cause any Participant no longer to be
     deemed a "disinterested person" within the meaning of Rule 16b-3, such
     provision will be construed or deemed amended to the extent necessary to
     conform to such requirements with respect to such Participant. In addition,
     the Board of Directors shall have no authority to make any amendment,
     alteration, suspension, discontinuation, or termination of the Plan or any
     agreement hereunder, to make any adjustment under Section 7, or take other
     action if and to the extent such authority would cause a Participant's
     transactions under the Plan not to be exempt, or would cause Participants
     no longer to be deemed "disinterested persons," under Rule 16b-3 under the
     Exchange Act.

     (e) Continued Service as an Employee. If a Participant ceases serving as a
     Director and, immediately thereafter, he or she is employed by the Company
     or any subsidiary, then solely for purposes of Sections 6(b) and (c) of the
     Plan, such Participant will not be deemed to have ceased service as a
     Director at that time, and his or her continued employment by the Company
     or any subsidiary will be deemed to be continued service as a Director;
     provided, however, that such former Director will not be eligible for
     additional grants of Options under the Plan.

     (f) No Right to Continue as a Director. Nothing contained in the Plan or
     any agreement hereunder will confer upon any Participant any rights to
     continue to serve as a Director of the Company.

                                       A-3

<PAGE>

     (g) No Stockholder Rights Conferred. Nothing contained in the Plan or any
     agreement hereunder will confer upon any Participant any rights of a
     stockholder of the Company unless and until an Option is duly exercised
     hereunder.

     (h) Governing Law. The place of administration of the Plan shall be
     conclusively deemed to be within the State of Texas; and the validity,
     construction, interpretation and effect of the Plan and all rights of any
     of the persons having or claiming to have any interest in the Plan shall be
     governed by the laws of the State of Texas.

10.  Effective Date and Duration of Plan. The Plan will be effective at the time
     stockholders of the Company have approved it by the affirmative votes of
     the holders of a majority of the shares of Stock present in person, or
     represented by proxy, and entitled to vote at a meeting of the Company's
     stockholders duly held in accordance with the Delaware General Corporation
     Law or any adjournment thereof. Unless earlier terminated by action of the
     Board of Directors, the Plan will remain in effect until such time as no
     Stock remains available for issuance or delivery under the Plan and the
     Company has no further rights or obligations with respect to outstanding
     Options under the Plan.

     Adopted by the Board of Directors:

                                                        April 19, 1994
