EXHIBIT 10.26

                    SEPARATION AGREEMENT AND GENERAL RELEASE


         This Separation Agreement and General Release (the "Agreement") is
between INPUT/OUTPUT, INC., a Delaware corporation ("Company"), and Kenneth W.
Pope, a resident of Magnolia, Texas ("Employee"), and is being presented to
Employee on this 24th day of January, 2003.

         WHEREAS, Company and Employee desire to resolve any and all potential
disputes, claims or causes of action arising out of Employee's employment with
and separation from Company and its subsidiaries;

         Therefore, in consideration of the mutual promises and covenants
contained herein, and effective the beginning of the eighth (8th) day after
Employee's execution of this Agreement (the "Effective Date"), and so long as
Employee does not revoke same during the prior seven (7) day period (the
"Revocation Period"), the parties voluntarily agree as follows:

         1. Employee's separation from Company and its subsidiaries effective
January 24, 2003 will be considered an elimination of position.

         2. Company will within 30 days of the Effective Date, pay to employee a
severance payment of $15,000.00 to be paid in 6-equal installments every two
weeks, with the first such payment due February 15, 2003. In addition, Company
will pay the reasonable expenses (per the attached relocation policy) you incur
to relocate you and your family to the Boulder, Colorado area if you chose to
move by May 1, 2004 and such expenses are incurred prior to August 1, 2004.
Employee acknowledges and agrees that the payments are in full and complete
satisfaction of any and all liabilities or obligations the Company has or may
have to Employee and that the payments represent something of value beyond
anything to which he is entitled. The payments in this paragraph 2 shall be
subject to any and all applicable withholding and other employment taxes.

         3. If Employee elects to continue any insurance benefits through COBRA,
the Company will pay any premiums in excess of Employee's portion of such
coverage while Employee was employed by the Company for up to one year.

         4. Company will vest 3,333 shares of currently unvested restricted
stock issued to Employee. The remaining 26,667 shares of restricted stock issued
to Employee shall be cancelled. Employee will have six months from the date of
this Agreement to exercise any options that have vested as of the date of this
Agreement. All of Employee's options that are not vested as of the date of this
Agreement shall be cancelled.

         5. Company also will engage an out-placement firm in order to provide
Employee out-placement assistance for a maximum of six (6) consecutive months,
and can be extended by mutual agreement of the parties on a month-to-month
basis, for up to 12 months. The provider of such out-placement assistance will
be selected and directed solely by Company. Outplacement services must be
utilized within a one year period ending January 25, 2003.

         6. In exchange for the consideration described in paragraphs 2 through
5 above, and as a material inducement to Company to enter into this Agreement,
except for the provisions of paragraph 10 below, Employee forever and
unconditionally releases and discharges Company and any of its parent,
subsidiary or affiliate companies or divisions and each of their owners,
shareholders, directors, officers,



                                       1




employees, assigns, representatives or agents ("Releasees") from any and all
claims, complaints or causes of action of any kind, including but not limited to
those relating to or arising out of Employee's employment with Company and its
subsidiaries and membership on or separation from the Boards of Directors of any
subsidiaries of Company, and such release encompasses, but is not limited to,
claims under local, state or federal law, alleged contract or tort claims or
claims or causes of action arising under any federal, state or local statutes,
including, but not limited to, Title VII, the Civil Rights Act of 1991, Section
1981, the Civil Rights Act of 1871, the Texas Commission on Human Rights Act and
the Age Discrimination in Employment Act.

         7. Employee further agrees that he will not file any complaint,
petition, or lawsuit or charge against Company or any of the Releasees with any
local, state or federal court, except to enforce this Agreement. If Employee or
anyone acting on his behalf files any such complaint, or if any such court
assumes jurisdiction of any complaint against Employee or any of the Releasees
regarding or involving Employee, he will request such court to withdraw from the
matter and dismiss said action and if initiated or pursued by his or with his
approval, will reimburse Company and/or the Releasees for all costs and
attorneys' fees incurred as a result of such lawsuit.

         8. Employee further agrees that Employee will not for two years
following the date of this Agreement, directly or indirectly, for himself or on
behalf of or in conjunction with any other person: (i) engage, as an officer,
director, shareholder, owner, partner, joint venturer or in a managerial
capacity, whether as an employee, independent contractor, consultant or advisor
or as a sales representative, in any business that competes with the products
and services offered by Company on the date of this Agreement; (ii) call upon
any person which is, at that time, or which has been, within one (1) year prior
to that time,. a customer of Company (including the direct or indirect
subsidiaries thereof) for the purpose of soliciting or selling products or
services in direct competition with the Company or any subsidiary of the
Company; or (iii) call upon any prospective acquisition candidate, on Employee's
own behalf or behalf of any competitor, which candidate was, to Employee's
actual knowledge after due inquiry, either called upon by the Company (including
the direct or indirect subsidiaries thereof) or for which the Company made an
acquisition analysis, for the purpose of acquiring such entity. Notwithstanding
the foregoing, this paragraph 8 shall not be deemed to prohibit Employee from
acquiring as an investment not more than two percent (2%) of the capital stock
of a competing business, whose stock is traded on a national securities exchange
or over-the-counter.

                  8.1. Employee acknowledges and agrees that failure to comply
         with this paragraph 8 shall constitute a material breach of this
         Agreement which shall entitle the Company to withhold all benefits and
         other consideration specified herein.

                  8.2. The covenants in this paragraph 8 are severable and
         separate, and the unenforceability of any specific covenant shall not
         affect the provisions of any other covenant. Moreover, in the event any
         court of competent jurisdiction shall determine that the scope, time or
         territorial restrictions set forth are unreasonable, then it is the
         intention of the parties that such restrictions be enforced to the
         fullest extent which the court deems reasonable, and the Agreement
         shall be reformed in accordance therewith.

                  8.3. All of the covenants in this paragraph 8 shall be
         construed as an agreement independent of any other provision in this
         Agreement, and the existence of any claim or cause of action of
         Employee against the Company, whether predicated on this Agreement or
         otherwise, shall not constitute a defense to the enforcement by the
         Company of such covenants.



                                       2




                  8.4. It is agreed by the parties that the foregoing covenants
         in this paragraph 8 impose a reasonable restraint on Employee in light
         of the activities and business of the Company (including the Company's
         direct and indirect subsidiaries) and the past and current duties of
         Employee. It is further agreed by the parties hereto that, in the event
         that Employee shall enter into a business or pursue other activities
         not in violation of this Section 8, Employee shall not be chargeable
         with a violation of this Section 8 if the person conducting such
         business or activities shall thereafter enter into a business or course
         of activities that is competitive with the Company, provided that
         Employee does not actively participate in any way in the business or
         course of activities that competes with the Company. It is further
         agreed by the parties hereto that, in the event Employee shall enter
         into a business or pursue other activities not in competition with the
         Company (including the Company's direct and indirect subsidiaries), and
         such new business or activities are not in violation of this Section 8
         or of Employee's obligations under this Section 8, Employee shall not
         be chargeable with a violation of this Section 8 if the Company
         (including the Company's direct and indirect subsidiaries) shall
         thereafter enter the same, similar or a competitive business or course
         of activities.

         9. Company forever and unconditionally releases and discharges
Employee, his heirs and assigns from any and all claims, complaints or causes of
action they might have relating to or arising out of Employee's employment with
Company, save and except any claims which might result from any gross misconduct
by Employee. Gross misconduct as used herein shall mean conduct such as, but not
limited to, misappropriation of property or dishonesty relating to Company's
business.

         10. The Company shall indemnify Employee in any instance in which
Employee is or was a party or is or was threatened to be made a party to any
action, suit, or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he (i) was an officer, employee or
agent of the Company or any of its direct or indirect wholly-owned subsidiaries,
or (ii) while an officer, employee or agent of the Company or any of its direct
or wholly-owned subsidiaries served at the request of the Company or any of its
direct or indirect wholly-owned subsidiaries, as an officer, employee, agent or
trustee of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including counsel fees),
judgments, fines, and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding, to the full
extent permitted by applicable laws, provided that the Company shall not be
obligated to indemnify Employee against any such action, suit or proceeding
which is brought by Employee against the Company or any of its direct or
indirect wholly-owned subsidiaries or the directors of the Company or any of its
direct or indirect wholly-owned subsidiaries, other than an action brought by
Employee to enforce his rights to indemnification hereunder, unless a majority
of the board of directors of the Company shall have previously approved the
bringing of such action, suit or proceeding.

         11. This Agreement shall not in any way be construed as an admission by
Company or the Releasees of any acts of illegal discrimination or violation of
any statute, law or right whatsoever against Employee or any other person, but
instead is entered into to ensure that the separation of employment is amicable.

         12. Employee agrees to return all company property which he received
during his tenure of employment and which is within his possession, custody and
control no later than the close of business on January 31, 2003. The term
"company property" as referred to in this paragraph 10 shall include but is not
limited to, all keys, credit cards, security cards, any and all files, and all
mechanical or office equipment. Employee acknowledges and agrees that failure to
return the company property as identified in this paragraph 12 shall constitute
a material breach of this Agreement which shall entitle the Company to withhold
all benefits and other consideration specified herein until Employee complies
with this paragraph 12.



                                       3




         13. All parties agree that they will keep the terms, amount and fact of
this Agreement completely confidential, and that they will not make any public
disparaging statements about the other, including any directors or employees of
the Releasees.

         14. Employee acknowledges that the Company's employees are valuable to
the Company's business and that information regarding the Company's employees,
including without limitation information as to their background, training and
compensation, is Confidential Information. Employee agrees that for a period not
to exceed twenty-four (24) months from the Effective Date of this Agreement, he
will not knowingly directly or indirectly solicit or otherwise induce or
encourage any person in the employment of the Company or any consultant to the
Company to terminate such employment or consulting arrangement or to accept
employment or enter into any consulting agreement with anyone other than the
Company.

         15. Further, Employee reaffirms the promises that he made to the
Company in the Employee Patent and Confidential Information Agreement that he
signed on December 31, 1997. Employee particularly acknowledges the binding
effect of the nondisclosure and confidentiality provisions of such agreement,
with regard to all confidential information which he received between December
31, 1997 and the Effective Date of this Agreement, and that such provisions
continue to apply at all times after the Effective Date of this Agreement.

         16. Employee acknowledges, understands and agrees that Company will
suffer immediate and irreparable harm if he fails to comply with any of his
obligations under paragraphs 13, 14 and 15 of this Agreement, and that monetary
damages will be inadequate to compensate Company for such breach. Accordingly,
Employee agrees that Company shall, in addition to any other remedies available
to them at law or in equity, be entitled to temporary, preliminary, and
permanent injunctive relief to enforce the terms of paragraphs 13, 14 and 15
without the necessity of proving inadequacy of legal remedies or irreparable
harm.

         17. As a further material inducement to enter into this Agreement, any
party who breaches this Agreement must reimburse the non-breaching party for any
and all loss, cost, damage or expense, including without limitation, attorneys'
fees, arising out of any breach of this Agreement. In addition, any breach of
this Agreement will entitle the non-breaching party to seek injunctive relief
and to recover any actual damages incurred as a result of said breach.

         18. Employee represents and acknowledges that in executing this
Agreement he does not rely and has not relied upon any prior representation made
by Company or its agents, representatives or attorneys with regard to the
subject matter of this Agreement.

         19. This Agreement shall be binding upon Employee and upon his heirs,
administrators, representatives, executors, successors and assigns.

         20. This Agreement shall in all respects be interpreted, enforced and
governed under the laws of the State of Texas and shall in all cases be
construed as a whole (according to its fair meaning, and not strictly for or
against any of the parties). Venue for any cause of action necessitated by
either party's material breach of the obligations hereunder shall be in Harris
County, Texas.



                                       4




         21. Should any provision of this Agreement be declared or be determined
illegal and invalid, the validity of the remaining parts will not be affected.

         22. This Agreement, contains the entire agreement and supersedes any
and all prior agreements and understandings, oral or written, between the
parties hereto with respect to the subject matter hereof and the employment of
Employee by the Company, and, except as otherwise expressly set forth herein,
any such prior agreements or understandings are hereby terminated. This
Agreement may not be changed orally, but only by an amendment in writing signed
by both parties.

         23. The parties agree that Employee may revoke this Agreement within
seven (7) days from execution of this Agreement. Failure of Employee to revoke
this Agreement during said seven (7) day Revocation Period shall mean it becomes
binding on all parties at 12:01 a.m. of the eighth day after Employee executes
same. Should Employee opt to revoke this Agreement during the said seven (7) day
Revocation Period, none of the obligations of Company set forth in this
Agreement shall become binding and shall be null and void. Employee shall give
