         The term of this Agreement will commence effective as of the Effective
Date, and, subject to the terms and conditions hereof, will continue for a
two-year period ending on June 15, 2006 (the "Initial Term"), and thereafter the

                  substantially perform his obligations under this Agreement
                  (other than any such failure resulting from his Disability)

                  in which






                                      -5-


                  the Board believes Employee has not substantially performed
                  such provisions and Employee has failed to remedy the
                  situation within ten (10) days after such demand or a willful
                  and material violation of the Employer's Code of Ethics;

                           (2) Employee's willfully engaging in conduct
                  materially and demonstrably injurious to the property or
                  business of Employer, including without limitation, fraud,
                  misappropriation of funds or other property of Employer, other

                  that he is in material breach of the Agreement, specifying the
                  particulars of such breach.

For purposes of this Agreement, no act, or failure to act, on the part of
Employee shall be deemed "willful" or engaged in "willfully" if it was due
primarily to an error in judgment or negligence, but shall be deemed "willful"
or engaged in "willfully" only if done, or omitted to be done, by Employee not
in good faith and without reasonable belief that his action or omission was in
the best interest of Employer. Notwithstanding the foregoing, Employee shall not
be deemed to have been terminated as a result of "Cause" hereunder unless and
until there shall have been delivered to Employee a copy of a resolution duly
adopted by the affirmative vote of not less than three-quarters of the Board
then in office at a meeting of the Board called and held for such purpose (after
reasonable notice to Employee and an opportunity for Employee, together with his
or her counsel, to be heard before the Board), finding that, in the good faith
opinion of the Board of Directors, Employee has committed an act set forth above
in this Section 5(c) and specifying the particulars thereof in detail. Nothing
herein shall limit the right of Employee or his or her legal representatives to
contest the validity or propriety of any such determination.

                  (d) As used in this Agreement, "Good Reason" means:

                           (1) Employer's failure to comply with any of the
                  provisions of Section 2 of this Agreement (including, but not
                  limited to, such a failure resulting from any reduction in the
                  Base Salary) which failure is not remedied within ten (10)
                  days after receipt of written notice from Employee specifying
                  the particulars of such breach;

                           (2) Employer's breach of any other material provision
                  of this Agreement which is not remedied within ten (10) days

                  specifying the particulars of such breach;

                           (3) the assignment to Employee of any duties
                  materially inconsistent with Employee's position, duties,
                  functions, responsibilities or authority as contemplated by
                  Section 1 of this Agreement; or





                                      -6-


                           (4) the relocation of Employee's principal place of
                  performance of his or her duties and responsibilities under
                  this Agreement to a location more than fifty miles (50) miles
                  from the Place of Employment;

                           (5) Any failure by Employer to comply with Section
                  9(c); or

                           (6) Any purported termination of Employee's
                  employment by Employer which is not effected pursuant to a
                  Notice of Termination satisfying the requirements of Section
                  5(e) hereof (and for purposes of this Agreement, no such
                  purported termination shall be effective).

                  (e) Any termination by Employer or Employee of Employee's
employment with Employer shall be communicated by written notice (a "Notice of
Termination") to the other party that shall:

                           (1) indicate the specific provision of this Agreement
                  relied upon for such termination;

                           (2) indicate the specific provision of this Agreement
                  pursuant to which Employee is to receive compensation and

                           (3) otherwise comply with the provisions of this
                  Section 5(e) and Section 11(a).

If a Notice of Termination states that Employee's employment with Employer has
been terminated as a result of Employee's Disability, the notice shall (i)
specifically describe the basis for the determination of Employee's Disability,
and (ii) state the date of the determination of Employee's Disability, which
date shall be not more than ten (10) days before the date such notice is given.
If the notice is from Employer and states that Employee's employment with
Employer is terminated by Employer as a result of the occurrence of Cause, the
Notice of Termination shall specifically describe the action or inaction of
Employee that Employer believes constitutes Cause and shall be accompanied by a
copy of the resolution satisfying Section 5(c). If the Notice of Termination is
from Employee and states that Employee's employment with Employer is terminated
by Employee as a result of the occurrence of Good Reason, the Notice of
Termination shall specifically describe the action or inaction of Employer that
Employee believes constitutes Good Reason. Any purported termination by Employer
of Employee's employment with Employer shall be ineffective unless such
termination shall have been communicated by Employer to Employee by a Notice of
Termination that meets the requirements of this Section 5(e) and the provisions
of Section 11(a).




                                      -7-

                  specified therein, provided that within such sixty (60) day
                  period Employee shall not have returned to full-time
                  performance of Employee's duties;

                           (2) if Employee's employment with Employer is
                  terminated as a result of Employee's death, the date of death
                  of Employee;

                           (3) if Employee's employment with Employer is
                  terminated for Cause, the date Notice of Termination,
                  accompanied by a copy of the resolution satisfying Section
                  5(c), is received by Employee or any later date specified
                  therein, provided that Employer may, in its discretion,
                  condition Employee's continued employment upon such
                  considerations or requirements as may be reasonable under the
                  circumstances and place a reasonable limitation upon the time

                  fourteen (14) days after the date of receipt of the Notice of
                  Termination.

                  Employer shall provide to Employee for one (1) year after the
                  Date of Termination, and provided that Employee has timely
                  elected under the Consolidated Omnibus Budget Reconciliation
                  Act of 1985, as amended ("COBRA"), to continue coverage under
                  such plan, Employer will, at no greater cost or expense to
                  Employee than was the case immediately prior to the Date of
                  Termination, maintain such continued coverage in full force
                  and effect.

Except as otherwise provided above and in Section 8, all other compensation and
benefits will cease upon the Date of Termination other than the following: (i)
those benefits that are provided by retirement and benefit plans and programs
specifically adopted and approved by Employer for Employee that are earned and
vested by the Date of Termination; (ii) any rights Employee or his survivors may
have under any grants of options to purchase Employer's Common Stock, restricted
stock grants, performance share grants, or other similar equity compensation
plans; and (iii) medical and similar benefits the continuation of which is
required by applicable law or as






                                      -9-


provided by the applicable benefit plan. As a condition to making the payments
and providing the benefits specified in this Section 6(c), Employer will require
that Employee execute a release of all claims Employee may have against Employer
at the time of Employee's termination. Such release will be in substantially the
same form as Exhibit A attached hereto.

Section 7. No Obligation to Mitigate; No Rights of Offset.

                  (a) Employee shall not be required to mitigate the amount of
any payment or other benefit required to be paid to Employee pursuant to this
Agreement, whether by seeking other employment or otherwise, nor shall the
amount of any such payment or other benefit be reduced on account of any
compensation earned by Employee as a result of employment by another person.

                  (b) Employer's obligation to make the payments provided for in
this Agreement and otherwise to perform its obligations hereunder shall not be
affected by any set-off, counterclaim, recoupment, defense or other claim, right
or action which Employer may have against Employee or others.

Section 8. No Effect on Other Rights.

         Nothing in this Agreement shall prevent or limit Employee's continuing
or future participation in any plan, program, policy or practice of or provided
by Employer or any of its affiliates and for which Employee may qualify, nor
shall anything herein limit or otherwise affect such rights as Employee may have
under any stock option or other agreements with Employer or any of its
affiliates. Amounts which are vested benefits or which Employee is otherwise
entitled to receive under any plan, program, policy or practice of or provided
by, or any other contract or agreement with, Employer or any of its affiliates
at or subsequent to the Date of Termination shall be payable or otherwise
provided in accordance with such plan, program, policy or practice or contract
or agreement except as explicitly modified by this Agreement.

Section 9. Successors; Binding Agreement.

                  (a) This Agreement is personal to Employee and without the
prior written consent of Employer shall not be assignable by Employee otherwise
than by will or the laws of descent and distribution. This Agreement shall inure
to the benefit of and be enforceable by Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.

                  (b) This Agreement shall inure to the benefit of and be
binding upon Employer and its successors and assigns.




                                      -10-


                  (c) Employer will require any successor (whether direct or
indirect, by purchase, merger, amalgamation, consolidation or otherwise) to all
or substantially all of the business and/or assets of Employer, by agreement in
form and substance reasonably satisfactory to Employee, to expressly assume and
agree to perform this Agreement in the same manner and to the same extent that
Employer would be required to perform it if no such succession had taken place.
As used in this Agreement, "Employer" shall mean Employer as hereinbefore
defined and any successor to its business and/or assets as aforesaid which
assumes and agrees to perform this Agreement by execution and delivery of the
agreement provided for in this Section 9(c) or which otherwise becomes bound by
the terms and provisions of this Agreement by operation of law or otherwise.

Section 10. Miscellaneous.

                  (a) All notices and other communications required or permitted
hereunder or necessary or convenient in connection herewith will be in writing
and will be delivered by hand or by registered or certified mail, return receipt
requested to the addresses set forth below in this Section 10(a):

                  If to Employer, to:

                           Input/Output, Inc.
                           12300 Parc Crest Drive
                           Stafford, TX  77477
                           Attention: Chief Financial Officer

                  If to Employee, to:

                           David L. Roland
                           12214 Cobblestone Drive
                           Houston, Texas  77024

or to such other names or addresses as Employer or Employee, as the case may be,
designate by notice to the other party hereto in the manner specified in this
Section.

                  (b) This Agreement (including the Exhibit(s) attached hereto)
supersedes, replaces and merges all previous agreements and discussions relating
to the same or similar subject matters between Employee and Employer and
constitutes the entire agreement between Employee and Employer with respect to
the subject matter of this Agreement, except for (i) the Employee Proprietary
Information Agreement referred to in Section 3(d) hereof, and (ii) the stock
option, restricted stock award and other agreements of the nature contemplated
under Section 8 hereof, each of which shall remain in full force and effect.
This Agreement may not be modified in any respect by any verbal statement,
representation or agreement made by any employee, officer, or representative of
Employer or by any written agreement unless signed by an officer of Employer who
is expressly authorized by the Board to execute such document.




                                      -11-


                  (c) If any provision of this Agreement or application thereof
to any one or under any circumstances should be determined to be invalid or
unenforceable, such invalidity or unenforceability will not affect any other
provisions or applications of this Agreement which can be given effect without
the invalid or unenforceable provision or application. In addition, if any
provision of this Agreement is held by an arbitration panel or a court of
competent jurisdiction to be invalid, unenforceable, unreasonable, unduly
restrictive or overly broad, the parties intend that such arbitration panel or
court modify said provision so as to render it valid, enforceable, reasonable
and not unduly restrictive or overly broad.

                  (d) The internal laws of the State of Texas will govern the
interpretation, validity, enforcement and effect of this Agreement without
regard to the place of execution or the place for performance thereof.

                  (e) The covenants, agreements, rights and obligations of
Employer under this Agreement, and the covenants, agreements, rights and
obligations of Employee under this Agreement, shall survive the termination of
this Agreement for any reason including, but not limited to, the termination of
Employee's employment with Employer. All covenants, agreements, indemnities,
warranties, rights and obligations contained herein shall continue for so long
as necessary in order for Employer and Employee to enforce their rights
hereunder.

Section 11. Arbitration.

                  (a) Employer and Employee agree to submit to final and binding
arbitration any and all disputes or disagreements concerning the interpretation
or application of this Agreement. Any such dispute or disagreement will be
resolved by arbitration in accordance with the National Rules for the Resolution
of Employment Disputes of the American Arbitration Association (the "AAA
Rules"). Arbitration will take place in Houston, Texas, unless the parties
mutually agree to a different location. Within 30 calendar days of the
initiation of arbitration hereunder, each party will designate an arbitrator.
The appointed arbitrators will then appoint a third arbitrator. Employee and
Employer agree that the decision of the arbitrators will be final and binding on
both parties. Any court having jurisdiction may enter a judgment upon the award
rendered by the arbitrators. In the event the arbitration is decided in whole or
in part in favor of Employee, Employer will reimburse Employee for his or her
reasonable costs and expenses of the arbitration (including reasonable
attorneys' fees).

                  (b) Notwithstanding the provisions of Section 11(a), Employer
may, if it so chooses, bring an action in any court of competent jurisdiction
for injunctive relief to enforce Employee's obligations under Sections 3(b),
3(c), 3(d), and 3(e).
