                                      FOR
                         ANNUAL MEETING OF STOCKHOLDERS
                          TO BE HELD OCTOBER 10, 1996

                   SOLICITATION AND REVOCABILITY OF PROXIES

     The Board of Directors of Input/Output, Inc., a Delaware corporation (the
"Company"), is soliciting proxies to be voted at the Annual Meeting of
Stockholders of the Company to be held at the Stafford Civic Center, 1415
Constitution Avenue, Stafford, Texas 77477, on Thursday, October 10, 1996 at
10:00 a.m., Stafford, Texas time, and at any adjournment thereof.  This Proxy
Statement and the enclosed proxy are first being mailed to stockholders on or
about September 5, 1996 in connection with this solicitation.

     This proxy solicitation is intended to afford stockholders the opportunity
to vote on the matters set forth in the accompanying Notice of Annual Meeting of
Stockholders dated September 5, 1996.  The proxy permits stockholders to
withhold voting for any or all nominees for election to the Company's Board of
Directors (the "Board") and to abstain from voting for any proposal if the
stockholder so chooses.

     All holders of record of shares of the Company's Common Stock at the close
of business on August 23, 1996 (the "Record Date"), are entitled to notice of
and to vote at the Annual Meeting.  On the Record Date, the Company had
outstanding 43,049,801 shares of common stock, par value $0.01 per share (the
"Common Stock").

     Each share of Common Stock is entitled to one vote.  The presence, in
person or by proxy, of holders of a majority of the outstanding shares of Common
Stock entitled to vote as of the Record Date is necessary to constitute a quorum
at the Annual Meeting.  A plurality of the votes of the shares present in person
or by proxy at the Annual Meeting, provided a quorum is constituted, is required
for the election of directors.  Approval of the proposal to amend the Company's
Restated Certificate of Incorporation requires the affirmative vote of holders
of a majority of the shares of Common Stock outstanding as of the Record Date. 
All other actions proposed herein may be taken upon the affirmative vote of
holders of a majority of the shares of Common Stock represented at the Annual
Meeting, provided a quorum is present in person or by proxy.

     With regard to the election of directors, votes may be cast in favor or
withheld; votes that are withheld will be excluded entirely from the vote and
will have no effect.  Abstentions may be specified on all other proposals and
will be counted as present for purposes of the item on which the abstention is
noted. Since the amendment to the Company's Certificate of Incorporation will
require the approval of holders of a majority of the outstanding shares of
Common Stock, abstentions will have the effect of a negative vote. In addition,
abstentions on the other specific proposals set forth herein will have the
effect of negative votes because these proposals require the affirmative vote of
holders of a majority of shares present in person or by proxy and entitled to
vote.  Under the rules of the New York Stock Exchange, Inc. ("NYSE"), brokers
who hold shares in street name for customers have the authority to vote on
certain "discretionary" items when they have not received instructions from
beneficial owners.  NYSE rules provide that brokers who have not received voting
instructions from their clients have discretion to give a proxy and to vote on
the election of directors and the other proposals set forth herein.  Under
applicable Delaware law, a broker non-vote will have no effect on the outcome of
the election of directors or the proposal to ratify the appointment of the
auditors,  nor will it count as a vote cast in determining 



                                    -1-


<PAGE>

the total affirmative votes cast on the proposal to adopt the 1996 Management 
Incentive Program, the proposal to adopt the 1996 Non-Employee Director Stock 
Option Plan or the proposal to amend the Amended and Restated 1990 Stock Option
Plan.  However, a broker non-vote will have the same effect as a vote against
the proposed amendment to the Restated Certificate of Incorporation.

     Any stockholder has the unconditional right to revoke his proxy at any time
before it is voted.  Any proxy given may be revoked either by a written notice
duly signed and delivered to the Secretary of the Company prior to the exercise
of the proxy, by execution of a subsequent proxy and delivery of such subsequent
proxy to the Secretary of the Company, or by voting in person at the Annual
Meeting (although attending the Annual Meeting without executing a ballot or
executing a subsequent proxy will not constitute revocation of a proxy). Where a
stockholder's duly executed proxy specifies a choice with respect to a voting
matter, the shares will be voted accordingly.  If no such specification is made,
the shares will be voted (i) FOR the nominees for director identified below,
(ii) FOR the approval of the proposed amendment to Article Fourth of the
Certificate of Incorporation of the Company to increase the number of authorized
shares of Common Stock from 50,000,000 to 100,000,000 shares, (iii) FOR the
adoption of the Input/Output, Inc. 1996 Management Incentive Program, (iv) FOR
the adoption of the Input/Output, Inc. 1996 Non-Employee Director Stock Option
Plan, (v) FOR the amendment of the Input/Output, Inc. Amended and Restated 1990
Stock Option Plan and (vi) FOR the ratification of  the appointment of KPMG Peat
Marwick LLP as the Company's independent certified public accountants for the
fiscal year ending May 31, 1997.

                              ELECTION OF DIRECTORS

     The Company's Certificate of Incorporation divides the Board into three
classes.  The term of office of one class of directors expires at this Annual
Meeting of Stockholders.  A second class of directors will serve until the 1997
Annual Meeting of Stockholders, and the third class of directors will serve
until the 1998 Annual Meeting of Stockholders.

     Charles E. Selecman, Dr. Peter T. Flawn, G. Thomas Graves III and Michael
J. Sheen, each of whom is currently a director of the Company with a term
expiring at the 1996 Annual Meeting, are nominees for director and will stand
for election at this year's Annual Meeting for a three-year term of office
expiring at the 1999 Annual Meeting of Stockholders or until their successors
are duly elected and qualified or until their earlier death, resignation or
removal.  For additional information regarding Messrs. Selecman, Flawn, Graves
and Sheen,  see "Management - Directors and Executive Officers of the Company." 
The persons named in the proxy will vote FOR such nominees, except where
authority has been withheld as to a particular nominee or as to all nominees.

     Nominees for director receiving a plurality of the votes represented by the
shares of Common Stock present in person or represented by proxy at the Annual
Meeting and entitled to vote thereon will be elected as directors.  Each nominee
has consented to being named in this Proxy Statement and to serve his term if
elected.  If any nominee should for any reason become unavailable for election,
proxies may be voted with discretionary authority by the persons named therein
for any substitute designated by the Board.

     THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE FOR EACH OF THESE NOMINEES FOR
ELECTION TO THE BOARD.

                   PROPOSAL TO INCREASE AUTHORIZED SHARES

THE PROPOSAL  

     The Board is seeking stockholder approval to amend Article Fourth of the
Company's Certificate of Incorporation to increase the number of authorized
shares of Common Stock, par value $0.01 per share, of the 



                                    -2-


<PAGE>

Company from 50,000,000 to 100,000,000 shares.   This proposal has been 
adopted by the Board subject to approval thereof by the stockholders of the 
Company and is attached hereto as Appendix I and made a part hereof; the 
following discussion is qualified in its entirety to such reference.

     At a Special Meeting of Stockholders of the Company held on March 4, 1996,
the Company's stockholders were asked to consider and approve an amendment to
the Company's Certificate of Incorporation to (i) increase the number of
authorized shares of Common Stock, par value $0.01 per share, of the Company
from 50,000,000 to 200,000,000 shares and (ii) increase the number of authorized
shares of preferred stock, par value $0.01 per share (the "Preferred Stock"), of
the Company from 5,000,000 to 25,000,000 shares.  Holders of approximately 46.5%
(19,633,133 shares) of the Company's outstanding Common Stock voted in favor of
this proposal; holders of approximately 30% (12,683,647 shares) voted against
the proposal and 286,280 shares (less than 1%) abstained.  Because the proposal
required for its approval the affirmative vote of a majority of shares of Common
Stock outstanding and entitled to vote at the meeting, it was therefore
rejected.  For the reasons discussed below, the Board of Directors considers the
number of currently authorized and unissued shares of Common Stock to be
inadequate to meet the Company's anticipated future requirements, and, as a
result of discussions with certain of its major stockholders, has determined to
re-propose for stockholder approval only an increase in the number of authorized
shares of Common Stock. Therefore, stockholders are not being asked to consider
an increase in the number of authorized shares of Preferred Stock at the Annual
Meeting.   

     The Company has accomplished two two-for-one stock splits (each effected as
a stock dividend) since May 1994, the latest split being declared in December
1995 and distributed to stockholders in January 1996.  As of the Record Date,
43,049,801 shares of Common Stock were outstanding.  Also, as of the Record
Date, 5,650,175 shares of Common Stock were reserved for issuance under the
Company's two existing stock option plans, leaving only 1,300,024 unreserved and
otherwise uncommitted shares of Common Stock available for future issuance. 
Assuming the proposed Non-Employee Director Stock Option Plan is approved by
stockholders at the Annual Meeting, then only 900,024 shares would remain
unreserved and available for future issuance.  

     The proposed increase in the authorized Common Stock has been recommended
by the Board to assure that an adequate supply of authorized and unissued shares
is available for general corporate needs, such as employee benefit plans, future
stock splits, stock dividends and other distributions to stockholders, raising
additional capital, financing arrangements, the conversion of other securities
(such as warrants and preferred stock) that may be issued by the Company, and
acquisitions by the Company of other businesses if favorable opportunities
become available.  Except for issuances of shares of Common Stock pursuant to
the Company's existing and proposed stock option plans as disclosed herein, the
Company has no present plans, arrangements or understandings to issue any
additional shares of Common Stock.

     If approved by the stockholders, the additional authorized shares of Common
Stock would be available for issuance at the discretion of the Board of
Directors without further stockholder approval (subject to applicable Delaware
law and NYSE rules), without the delay and expense incident to the holding of a
special meeting of stockholders to consider any specific issuance.  However, the
rules of the NYSE require stockholder approval (i) in connection with the
acquisition of certain stock or assets, including another business, from a
director, officer or substantial stockholder, or from an entity in which one of
such persons has a substantial direct or indirect interest, (ii) in a
transaction or a series of transactions (except for a public offering of Common
Stock for cash) that would result in an increase in the number of shares or
voting power of the outstanding shares by 20% or more, (iii) where the issuance
of Common Stock would result in a change of control of the Company or (iv) in
connection with a stock option or stock purchase plan under which stock may be
acquired by officers or directors.

     While the Board of Directors is of the opinion that the proposed amendment
is in the best interests of the Company and its stockholders, the Board
recognizes that there may be some disadvantages to the stockholders.  



                                    -3-

<PAGE>

The authorized but unissued shares of Common Stock could be used by incumbent 
management to make more difficult a change in control of the Company.  Under 
certain circumstances, such shares could be used to frustrate persons seeking 
to effect a takeover or otherwise gain control of the Company.  The increase 
in authorized shares of Common Stock might also be considered as having the 
effect of discouraging an attempt by another person or entity, through 
acquisition of a substantial number of shares of the Common Stock, to acquire 
control of the Company with a view to imposing a merger, sale of all or any 
part of the Company's assets or a similar transaction, since the issuance of 
any shares could be used to dilute the stock ownership of shares of the 
Company's voting stock held by such person or entity.  Any transaction which 
may be so discouraged or avoided could be a transaction that the Company's 
stockholders might consider to be in their best interests, although it should 
be noted that the Board of Directors has a fiduciary duty to act in the best 
interests of the Company's stockholders at all times.  See also "-- Potential 
Anti-Takeover Effects of Proposal." 

     The Company's Board of Directors has not proposed the amendment to the 
Certificate of Incorporation as an anti-takeover measure, nor does the Board 
presently intend for the foreseeable future to propose anti-takeover measures 
in any future proxy solicitations.  Any actions taken by the Company to 
discourage an attempt to acquire control of the Company may result in 
stockholders not being able to participate in any possible premiums which may 
arise in the absence of anti-takeover provisions, as well as may be used to 
entrench management's position even if such change in control may be 
beneficial to stockholders.

     The approval of the amendment to Article Fourth of the Certificate of 
Incorporation will not of itself cause any change in the capital stock or 
surplus of the Company.  However, any future issuance of shares of Common 
Stock may have a dilutive effect on the present equity holdings of 
stockholders of the Company.

DESCRIPTION OF CAPITAL STOCK  

     The Common Stock for which authorization is sought would become part of 
the existing class of Common Stock.  The new shares, when issued, would have 
the same rights and privileges as the shares of Common Stock presently 
outstanding. No stockholder of the Company has any preemptive right to 
subscribe for or purchase any of the shares of Common Stock, and, once 
authorized, such shares would be available for issuance at such time and on 
such terms as the Board of Directors may consider appropriate.

     Holders of Common Stock are entitled to such dividends as may be 
declared from time to time by the Board of Directors out of funds legally 
available therefor.  The Company has not paid any cash dividends on the 
Common Stock since inception.

     Holders of the Common Stock have no redemption, conversion or sinking 
fund rights.  Holders of Common Stock are entitled to one vote per share on 
all matters submitted to a vote of holders of Common Stock and do not have 
any cumulative voting rights.  In the event of a liquidation, dissolution or 
winding-up of the Company, the holders of Common Stock are entitled to share 
equally and ratably in the assets of the Company, if any, remaining after the 
payment of all debts and liabilities of the Company and the liquidation 
preference of any outstanding Preferred Stock.

     The Board of Directors is authorized to provide for the issuance of 
Preferred Stock in one or more series and to fix the designations, 
preferences, powers and relative, participating, optional or other rights and 
restrictions thereof, including without limitation, the dividend rate, 
conversion rights, voting rights, redemption price and liquidation 
preference, to fix the number of shares constituting any such series and to 
increase and decrease the number of shares of such series.  The Board of 
Directors of the Company, without obtaining stockholder approval, may issue 
shares of Preferred Stock with voting rights or conversion rights which could 
adversely affect the voting power of the holders of Common Stock.  The 
Company's Certificate of Incorporation currently authorizes the Company to 
issue up to 5,000,000 shares of Preferred Stock.  The proposed amendment 

                                     -4- 
<PAGE>

would effect no change in the Company's authorized Preferred Stock.  No 
shares of Preferred Stock have ever been issued, and the Company has no 
present plans to issue any shares of Preferred Stock.

POTENTIAL ANTI-TAKEOVER EFFECTS OF PROPOSAL  


     The additional shares of Common Stock proposed to be authorized would be 
available for issuance by the Board in opposing an attempt by another 
corporation or individual to acquire or to take control of the Company which 
management may deem to not be in the best interests of the Company.  For 
example, the Company might seek to frustrate a takeover attempt by making a 
private sale of a large block of shares to a third party who was opposed to 
such an attempt or by issuing shares of Preferred Stock or stock rights to 
stockholders, which shares or rights would acquire certain characteristics 
(such as conversion or redemption rights) upon an unfriendly attempted 
takeover. 

     The provisions of the Company's Certificate of Incorporation and Bylaws 
summarized in the succeeding paragraphs may be deemed to have an 
anti-takeover effect and may delay, defer or prevent a tender offer or 
takeover attempt that a stockholder might consider in such stockholder's best 
interest, including those attempts that might result in a premium over the 
market price for the shares held by stockholders.

     The Board of Directors of the Company is divided into three classes that 
are elected for staggered three-year terms.  Stockholders may only remove a 
director for cause.

     Pursuant to the Certificate of Incorporation, the Company's Board of 
Directors by resolution may establish one or more series of Preferred Stock 
having such number of shares, designations, relative voting rights, dividend 
rates, liquidation and other rights, preferences and limitations as may be 
fixed by the Board of Directors without any further stockholder approval.  
These include, among other things, each share having more than one vote, 
voting as a class on certain matters, and special conversion rights or 
redemption features. Such rights, preferences, powers and limitations as may 
be established could have the effect of impeding or discouraging the 
acquisition of control of the Company.

     The Company's Certificate of Incorporation contains a "fair price" 
provision that requires the approval of holders of not less than 75% of the 
outstanding shares of voting stock of the Company (including not less than 
66-2/3% of the outstanding shares of  voting stock not owned, directly or 
indirectly, by persons who are Related Persons [as defined below]) as a 
condition for mergers, consolidations and certain other business 
combinations, including management buyouts, involving the Company and any 
Related Person, provided that the 66-2/3% voting requirement is not 
applicable if the business combination is approved by the holders of not less 
than 90% of the outstanding shares of voting stock of the Company. Related 
Persons include the holders of 10% or more of the Company's outstanding 
voting stock and any affiliate of such persons.  The 75% voting requirement 
of the "fair price" provision is not applicable to a business combination 
between the Company and any wholly-owned subsidiary or a business combination 
involving a holder of 10% or more of the Company's outstanding voting stock 
if the acquisition by such holder of such stock or the proposed transaction 
is approved in advance of such person becoming a holder of 10% of the 
Company's outstanding voting stock by not less than 75% of the directors of 
the Company then holding office or the following conditions are met: (i) the 
transaction is a merger or consolidation proposed to occur within one year of 
the time such holder acquired 10% of the Company's outstanding voting stock 
and the price to be paid to holders of Common Stock is at least as high as 
the highest price paid by such holder in acquiring any of its Common Stock, 
(ii) the consideration to be paid in the transaction is cash or the same form 
of consideration paid by such holder to acquire a majority of its holdings of 
Common Stock, (iii) between the date of the acquisition by such holder of 10% 
of the Company's outstanding voting stock and the transaction there has been 
no failure to declare and pay Preferred Stock dividends and no reduction in 
Common Stock dividends (except as approved by a majority of the unaffiliated 
directors), no further acquisition of voting stock by such holder and no 
benefit, direct or indirect, received by such holder through 

                                     -5- 
<PAGE>

loans or other financial assistance from the Company or tax credits or other 
tax advantages provided by the Company and (iv) a proxy statement shall have 
been mailed to stockholders of record at least 30 days prior to the 
consummation of the transaction for the purpose of soliciting stockholder 
approval of such transaction.

     The Company's Certificate of Incorporation further provides that (i) 
stockholders may act only at an annual or special meeting of stockholders and 
may not act by written consent, (ii) special meetings of stockholders can be 
called only by the Board of Directors, (iii) a 75% vote of the outstanding 
voting stock is required to amend the Certificate of Incorporation with 
respect to certain matters, including, without limitation, the matters set 
forth in clause (i) above and the 75% voting requirement for certain business 
combinations described in the preceding paragraph and (iv) in addition to the 
75% voting requirement referred to in clause (iii), a 66-2/3% vote of the 
outstanding shares of voting stock of the Company not owned by a Related 
Person is required to amend the provisions of the Certificate of 
Incorporation relating to certain business combinations described in the 
preceding paragraph.

     The Company's Bylaws provide that they may be amended only by the Board 
of Directors or the vote of not less than 75% of the outstanding shares of 
voting stock of the Company.  The Bylaws also establish advance notice 
procedures with regard to the nomination, other than by or at the direction 
of the Board of Directors or a committee thereof, of candidates for election 
as directors and with regard to certain matters to be brought before a 
special meeting of stockholders of the Company.  These procedures provide 
that the notice of proposed stockholder nominations for the election of 
directors must be timely given in writing to the Secretary of the Company 
prior to the meeting at which directors are to be elected.  To be timely, 
notice must be received at the principal executive office of the Company not 
less than 30 days nor more than 60 days prior to the meeting (or if fewer 
than 40 days notice or prior public disclosure of the meeting date is given 
or made by the Company, not later than the 10th day following the day on 
which the notice was mailed or such public disclosure was made).  The 
procedures also provide that at an annual meeting of stockholders, and 
subject to any other applicable requirements, only such business may be 
conducted as has been brought before the meeting by, or at the direction of 
the Board of Directors or by a stockholder who has given  timely prior 
written notice to the Secretary of the Company of such stockholder's 
intention to bring such business before the meeting.  For such stockholder's 
notice to be timely, notice must be delivered to or mailed and received at 
the principal executive offices of the Company not later than the date that 
corresponds to 120 days prior to the date the Company's proxy statement was 
released to stockholders in connection with the previous year's annual 
meeting of stockholders.  Such notice must contain certain information as 
specified in the Bylaws.

     The affirmative vote of holders of a majority of shares of Common Stock 
outstanding and entitled to vote at the Annual Meeting as of the Record Date 
is required to approve the amendment to the Company's Certificate of 
Incorporation, provided a quorum is present.

     THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE 
PROPOSED AMENDMENT TO THE COMPANY'S CERTIFICATE OF INCORPORATION.


                    PROPOSAL TO ADOPT THE INPUT/OUTPUT, INC.
                        1996 MANAGEMENT INCENTIVE PROGRAM

GENERAL

     On July 12, 1996, the Board adopted the Input/Output, Inc. 1996 
Management Incentive Program (the "Incentive Plan"), subject to approval by 
the Company's stockholders at the Annual Meeting.

     During 1993, the United States Congress adopted Section 162(m) of the 
Internal Revenue Code of 1986 (the "Code"), which provision places limits on 
the Company's ability to deduct certain compensation in excess 

                                     -6- 
<PAGE>

of $1,000,000 for any taxable year paid to certain of its executive officers 
("Section 162(m)").  One exception to these limitations is for 
"performance-based" compensation that has been disclosed to and approved by 
stockholders prior to payment of the awards. Final federal income tax 
regulations were promulgated in December 1995, which provide guidelines for 
compliance with this exception to the deduction limitation rules.

     The Incentive Plan was approved by the Compensation Committee in July 
1996 to replace the Company's existing Management Incentive Plan and in 
response to Section 162(m) and the adoption of the final treasury regulations 
thereunder.  The Incentive Plan is intended to comply with the 
performance-based exception to Section 162(m).  Assuming the Incentive Plan 
is approved by the stockholders, the Incentive Plan will terminate on July 
12, 2001, unless sooner terminated by action of the Board (Article X of the 
Incentive Plan).

     The provisions of the Incentive Plan (which include the material terms 
of the performance-based compensation that the Company intends to pay 
pursuant to the Incentive Plan) are summarized below.  The statements herein 
concerning the terms and provisions of the Incentive Plan are summaries only 
and are qualified in their entirety by reference to the full text of the 
Incentive Plan, a copy of which is attached hereto as Appendix II. 

     The purpose of the Incentive Plan is to advance the interests of the 
Company and its stockholders by providing certain of the Company's key 
employees with annual incentive compensation which is tied to the achievement 
of preestablished and objective performance goals.  The Incentive Plan is 
designed to provide the Company with flexibility in achieving those purposes 
and to implement performance-based compensation strategies that will attract 
and retain officers and employees who are important to the long-term success 
of the Company.

     The Compensation Committee shall within 90 days after the commencement 
of each fiscal year, select the particular key employees of the Company and 
its subsidiaries to whom bonuses under the Incentive Plan may be granted. 
Approximately 53 employees are currently eligible to participate in the 
Incentive Plan. Subject to the terms of the Incentive Plan, employees who 
participate in the Incentive Plan may also participate in other benefit plans 
of the Company or any of its subsidiaries (Articles III and IV of the 
Incentive Plan).

     The Incentive Plan is administered by the Compensation Committee of the 
Board of Directors, each of whom is required by the terms of the Incentive 
Plan to be an "outside director" as that term is defined under Section 
162(m).  See "Proposal to Approve Amendments to the Input/Output, Inc. 
Amended and Restated 1990 Stock Option Plan -- Administration of the 1990 
Plan."

BONUSES UNDER THE INCENTIVE PLAN

     Bonuses will be calculated and awarded under the Incentive Plan 
according to the participant's position within the Company.  Participants will 
be classified into Groups as designated by the Compensation Committee from 
time to time. Initially, Group I shall consist of the Chief Executive Officer 
and Chief Operating Officer of the Company (currently comprised of one 
person); Group II shall consist of the vice presidents and the controller of 
the Company (seven persons); Group III shall consist of certain tier one key 
employees of the Company and its Subsidiaries as designated by the 
Compensation Committee (11 persons); and Group IV shall consist of certain 
tier two key employees of the Company and its Subsidiaries as designated by 
the Compensation Committee (34 persons).

     BUDGET AND PBT BONUS.  Under the Incentive Plan, a bonus may be awarded 
based upon the extent to which actual Profits Before Taxes for a fiscal year 
exceed a percentage (not less than 80%), as designated by the Compensation 
Committee from year to year, of that year's Budgeted Profit Before Taxes (as 
defined in Article I 

                                     -7- 
<PAGE>

of the Incentive Plan) (a "Budget Bonus").  A bonus may also be awarded based 
upon the extent to which actual Profits Before Taxes for the relevant fiscal 
year exceed Profits Before Taxes for the immediately preceding fiscal year (a 
"PBT Bonus").  The Incentive Plan provides that the Compensation Committee 
must, within 90 days after the commencement of the fiscal year in question, 
establish the Corporate Thresholds and Performance Goals for that year, each 
of which is described below.

     Corporate Thresholds shall be the minimum levels of Profits Before Taxes 
that must be realized by the Company before payment of  any Budget Bonus or 
PBT Bonus, as the case may be.  The Performance Goals for each bonus year 
shall be those performance measures established by the Compensation Committee 
for each Group, which shall be expressed as percentages.  These applicable 
percentages will be multiplied by the base salaries of participants in 
determining their respective bonus amounts.  The amounts of these percentages 
will be determined by reference to the extent that actual Profits Before 
Taxes exceed the Corporate Thresholds with respect to any bonus year; 
provided that the maximum Budget Bonus that may be received by a Participant 
may not exceed twenty-five percent (25%) of such participant's base salary 
for such bonus year.

     ADJUSTMENTS AND LIMITATION ON BONUS.  The maximum bonus amounts as 
calculated above for any participant who is a "covered employee" under 
Section 162(m) may be reduced by an amount of up to 50% by the Compensation 
Committee in its sole discretion; however, the total maximum bonus amounts to 
any such participant may not be increased.  Bonus amounts calculated under 
the Incentive Plan for all other participants may be increased or decreased 
by the Committee in its sole discretion.  In any event, the maximum total 
bonus amount payable to any participant with respect to any bonus year shall 
not exceed $750,000.

NEW PLAN BENEFITS

     As discussed above, bonuses under the Incentive Plan will be based upon 
performance goals with respect to fiscal 1997 and future years.  No incentive 
compensation under these terms has yet been earned by any participant. 
Accordingly, the amount of annual incentive compensation to be paid in the 
future to participants, including the Company's current or future named 
executive officers subject to Section 162(m), cannot be determined at this 
time, since actual amounts will depend on actual performance measured against 
the attainment of the preestablished performance goals and the Compensation 
Committee's discretion to adjust such amounts.  However, the following table 
provides certain summary information concerning maximum bonuses which could 
have been awarded in fiscal 1996 to Mr. Owens, the Company's Chief Executive 
Officer, the named executive officers, the Company's executive officers as a 
group and all non-executive employees as a group, if the Incentive Plan had 
been in effect:

INCENTIVE PLAN.


                  PROPOSAL TO ADOPT THE INPUT/OUTPUT, INC. 1996
                     NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

GENERAL

     The Company's existing Amended and Restated 1991 Outside Directors Stock 
Option Plan (the "1991 Plan") was adopted at the Company's 1991 Annual 
Meeting of Stockholders and amended in 1994.  As so amended, the 1991 Plan 
authorized the automatic grant of options to purchase shares of Common Stock 
on an annual basis, to each outside director of the Company (an "Outside 
Director") through 1996. The option grants to be made to each Outside 
Director on October 1, 1996 will represent the final grants of options under 
the 1991 Plan. See "Remuneration of Directors and Officers -- Compensation of 
Directors." As a means to attract and recruit qualified new directors and to 
retain capable directors in a manner that promotes ownership of a proprietary 
interest in the Company, the Board of Directors of the Company adopted, 
subject to stockholder approval, the Input/Output, Inc. 1996 Non-Employee 
Director Stock Option Plan (the "Directors' Plan"), effective as of July 12, 
1996.

     The Directors' Plan provides that each individual serving as an Outside
Director on the first business day of November 1996 will automatically receive a
nonqualified stock option to purchase 20,000 shares of Common Stock and that
each Outside Director who joins the Company's Board of Directors in the future
will 


                                      -9-


<PAGE>

automatically receive a nonqualified stock option to purchase 20,000 shares 
of Common Stock on the date on which such person is first elected or begins 
to serve as an Outside Director.  This first grant of a stock option for 
20,000 shares is herein referred to as the "First Grant".  Additionally, 
Outside Directors will receive a stock option to purchase 10,000 shares of 
Common Stock (the "Second Grant") on the first business day of the November 
immediately succeeding the First Grant and a stock option to purchase 10,000 
shares of Common Stock (the "Third Grant") on the first business day of the 
November immediately succeeding the Second Grant.  The First Grant stock 
options shall vest in 33.33% installments on the first, second, and third 
anniversary dates of the First Grant.  The Second Grant stock options shall 
vest in 50% installments on the first and second anniversary dates of the 
Second Grant.  The Third Grant stock options shall be fully exercisable on 
and following the first anniversary date of the Third Grant.

     The provisions of the Directors' Plan are summarized below.  All such
statements are qualified in their entirety by reference to the full text of the
Directors' Plan, which is attached hereto as Appendix III.

     The Directors' Plan is not subject to the provisions of ERISA and is not a
"qualified plan" within the meaning of Section 401 of the Code.  The Directors'
Plan will terminate on July 12, 2006, and thereafter no options may be granted
thereunder.  The holder of an option granted pursuant to the Directors' Plan
does not have any of the rights or privileges of a stockholder except with
respect to shares that have been actually issued. 

PURPOSE AND ELIGIBILITY

     Only Outside Directors of the Company are eligible to receive options under
the Directors' Plan.  At the present time, seven members of the Company's Board
of Directors are considered Outside Directors for purposes of the Directors'
Plan: Charles E. Selecman, Shelby H. Carter, Jr., Ernest E. Cook, Glen H.
Denison, Theodore H. Elliott, Jr., Dr. Peter T. Flawn, and G. Thomas Graves III.

     The purpose of the Directors' Plan is to promote the long-term growth of
the Company by increasing the proprietary interest of Outside Directors in the
Company, and to attract, recruit and retain highly qualified and capable Outside
Directors by allowing these directors to participate in the long-term growth and
financial success of the Company, particularly in light of the discontinuance of
the Company's Directors Retirement Plan.  See "Remuneration of Directors and
Officers - Compensation of Directors."

ADMINISTRATION OF THE DIRECTORS' PLAN

     The Directors' Plan shall be administered by the Compensation Committee of
the Board of Directors.  See "Proposal to Approve Amendments to the
Input/Output, Inc. Amended and Restated 1990 Stock Option Plan--Administration
of the 1990 Plan."
          
STOCK OPTIONS

     The maximum number of shares of Common Stock to be authorized for issuance
under the Directors' Plan is 400,000, subject to adjustment for stock splits and
similar events.  Shares that by reason of the expiration or unexercised
termination of a stock option are no longer subject to purchase may be reoffered
under the Directors' Plan.  Each stock option granted under the Directors' Plan
is required to be evidenced by a stock option agreement, which sets forth the
material terms and provisions of the stock option. 

     The exercise price for an option granted under the Directors' Plan shall be
equal to the Fair Market Value per share of the Common Stock on the date of
grant, but in any event shall not be less than the par value per share of the
Common Stock.  The option period extends for ten years from the date the option
is granted, subject to earlier termination in the event a director ceases to
serve as such.


                                     -10-


<PAGE>

     On the date that the participant desires to exercise stock options, the
participant is required to deliver to the Company the total exercise price of
the shares to be purchased in cash or in shares of Common Stock owned by the
participant having a Fair Market Value equal to the exercise price (or in any
combination of cash and shares of Common Stock having an aggregate Fair Market
Value equal to the exercise price). 

RESTRICTIONS

     The options granted and to be granted under the Directors' Plan are not
transferable or assignable other than by will or by the laws of descent and
distribution or pursuant to the terms of a qualified domestic relations order as
defined in the Code.

     Stock options may be exercised at any time during the option period, at
such times and in such amounts, in accordance with the terms and conditions and
subject to such restrictions as are set forth in the Directors' Plan and in the
applicable stock option agreements.  Upon termination of the participant's
service as a director with the Company and its subsidiaries due to death, total
and permanent disability or retirement, all unmatured installments of options
outstanding shall thereupon automatically be accelerated and exercisable in
full, and the option may be exercised for a period of 12 months after such
termination of service, or until expiration of the stock option period
(whichever is sooner), by the participant or his estate or personal
representative, or by the person who acquired the right to exercise the option
by bequest or inheritance or by reason of the participant's death. 

     In the event of the termination of a participant's service as a director
other than as a result of death, disability, or retirement, such participant's
stock options may be exercised by the participant for a period of 180 days after
the participant's termination of service, or until expiration of the applicable
option period (whichever is sooner) to the extent of the shares with respect to
which such options could have been exercised by the participant on the date of
termination, and thereafter to the extent not so exercised, such options shall
terminate. 

ADJUSTMENTS; AMENDMENTS

     The Directors' Plan provides that the number of shares issuable under the
Directors' Plan and upon exercise of outstanding options and the exercise prices
of such options are subject to such adjustments as are appropriate to reflect
any increase or decrease in the number of issued and outstanding shares of
Common Stock through the declaration of a stock dividend or through any
recapitalization resulting in a stock split-up, combination, or exchange of
shares of Common Stock (Article X of the Directors' Plan).

     If the Company merges or consolidates, transfers all or substantially all
of its assets to another entity or dissolves or liquidates, then under certain
circumstances a holder of an option will be entitled to purchase the equivalent
number of shares of stock, other securities, cash or property that the option
holder would have been entitled to receive had he or she exercised his or her
option immediately prior to such event.

     In the event of a "Change in Control" of the Company (as defined in
Article I of the Plan), then, notwithstanding any other provision in the
Directors' Plan to the contrary, all unmatured installments of stock options
outstanding shall thereupon automatically be accelerated and exercisable in full
(Article XI of the Directors' Plan).

     The Directors' Plan provides that the Board of Directors may from time to
time discontinue or amend the Directors' Plan without the consent of the
stockholders unless such discontinuance or amendment is required by applicable
law, rule or regulation (Article VII of the Directors' Plan).  In addition, the
Board of Directors may amend the Directors' Plan in any manner advisable in
order for stock options to qualify for the exemption 


                                     -11-


<PAGE>

granted under Section 16(b) (and any changes or amendments thereto) of the 
Securities Exchange Act of 1934 (the "1934 Act"). 

CERTAIN FEDERAL INCOME TAX ASPECTS

     The granting of a stock option under the Plan will not result in federal
income tax consequences to either the Company or the optionee.  Upon exercise of
a stock option, the optionee will recognize ordinary income in an amount equal
to the difference between the fair market value of the shares on the date of
exercise and the exercise price, and the Company will be entitled to a
corresponding deduction.  See "Proposal to Adopt Amendments to the Input/Output,
Inc. Amended and Restated 1990 Stock Option Plan - Certain Federal Income Tax
Aspects -- Nonqualified Stock Options."

     The affirmative vote of the holders of a majority of the shares of Common
Stock represented in person or by proxy at the Annual Meeting and entitled to
vote thereon, provided a quorum is present, is required to adopt the Directors'
Plan.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO APPROVE THE
DIRECTORS' PLAN.


             PROPOSAL TO ADOPT AMENDMENTS TO THE INPUT/OUTPUT, INC.
                   AMENDED AND RESTATED 1990 STOCK OPTION PLAN

GENERAL

     The Company's Amended and Restated 1990 Stock Option Plan was adopted at
the  1990 Annual Meeting of Stockholders and subsequently amended in 1994.   In
July 1996,  the Board approved, subject to approval by the Company's
stockholders, certain amendments to the 1990 Plan.  The Amended and Restated
1990 Stock Option Plan, as proposed to be amended by the terms hereof, is
referred to herein as the "1990 Plan" and is summarized below. 

     The amendments to the 1990 Plan have been approved by the Compensation
Committee in response to Section 162(m) and the adoption in December 1995 of the
final treasury regulations thereunder, in order for compensation attributable to
future stock options granted under the 1990 Plan to be "performance-based"
compensation exempt from the limitations of Section 162(m).  See "Proposal to
Adopt the Input/Output, Inc. 1996 Management Incentive Program -- General."  The
principal amendment in this regard limits the aggregate number of shares of
Common Stock represented by grants of stock options to be made to any individual
participant during any four-year period to 750,000 shares (Section 5 of the 1990
Plan).  An additional related amendment requires that each member of the
Compensation Committee be an "outside director" as that term is defined under
Section 162(m).

     If the proposed amendment to the 1990 Plan is not approved by the
stockholders, the Board intends to rescind the amendment and seek, at a
subsequent meeting, stockholder approval of other amendments that will meet with
the approval of the stockholders and bring the 1990 Plan into compliance with
Section 162(m).

     Other principal amendments to the 1990 Plan include:

        (i)  Amendments which provide that Nonqualified Stock Options terminate
             180 days after the termination of an optionee's employment with 
             the Company, except that if such optionee's employment is 
             terminated by reason of death, total and permanent disability, or 
             retirement 


                                     -12-


<PAGE>

             pursuant to Company policies, such options terminate one year 
             after such termination (Section 6 of the 1990 Plan); and

       (ii)  Amendments which clarify the Board's authority to amend the 1990 
             Plan in order to continue to qualify under Section 162(m) of the 
             Code and with respect to certain exemptions from Section 16(b) of 
             the 1934 Act (Section 12 of the 1990 Plan); and

      (iii)  An amendment to the definition of a "Change in Control" of the 
             Company (Section 8 of the 1990 Plan).

     The statements herein concerning the terms and provisions of the 1990 Plan
are summaries only and are qualified in their entirety by reference to the full
text of the 1990 Plan, as proposed to be amended and restated, a copy of which
is attached hereto as Appendix IV. 

      At May 31, 1996, the Company estimates that approximately 1,000 employees
and officers were eligible to participate in the 1990 Plan, 210 of whom were
participants.  As of May 31, 1996, options to purchase 1,984,500 shares of
Common Stock had been granted to 210 persons and were outstanding under the 1990
Plan at exercise prices ranging from $2.03 to $39.25 per share, leaving
2,038,950 shares of Common Stock available for option grants.  As of May 31,
1996, the aggregate market value of the shares of Common Stock underlying
outstanding options under the 1990 Plan was $80,124,187 (based on the closing
sales price per share of $40.375 on the New York Stock Exchange composite tape
on such date.)

     For information concerning stock options granted during fiscal 1996 under
the 1990 Plan to the named executive officers, the Company's executive officers
as a group, all non-employee directors as a group, and all non-executive
employees as a group, see "Remuneration of Directors and Officers - Stock
Options."  

TERMS OF THE 1990 PLAN AND AGREEMENTS

     TERM.  Unless sooner terminated by action of the Board, the 1990 Plan will
terminate on September 1, 2000, and thereafter no options may be granted
thereunder.  

     EMPLOYEES.  The Compensation Committee will have authority to grant stock
options to key employees of the Company (including officers and directors who
are employees) or any majority-owned subsidiary at such time, in such amounts
and under such terms as the Compensation Committee determines in accordance with
the 1990 Plan.

     EXERCISE OF OPTIONS.  The exercise price may be paid in cash or in shares
of Common Stock valued at their fair market value on the date of exercise (or in
any combination of cash and shares of Common Stock having an aggregate fair
market value equal to the exercise price).  The Compensation Committee is
authorized to prescribe the time or times at which a stock option granted under
the 1990 Plan may be exercised (Section 6(c) of the 1990 Plan).

     TERMINATION OF EMPLOYMENT OR SERVICE.  The 1990 Plan states that upon
termination of an optionee's employment with the Company, his option will be
exercisable for a period of 180 days after such termination; provided, however,
that if such termination is by reason of death, total and permanent disability,
retirement or otherwise, as the case may be, his option will automatically vest
and become fully exercisable for a period of 12 months after such date of 
termination.


                                     -13-

<PAGE>

     The 1990 Plan provides that in the event of a "Change in Control" of the 
Company, all stock options will become fully exercisable and vested, 
regardless of provisions under option agreements requiring shares to be 
exercised in installments.  "Change in Control" is defined in Section 8 of 
the 1990 Plan.

ADMINISTRATION OF THE 1990 PLAN

     The 1990 Plan is administered by the Compensation Committee of the 
Board. The Compensation Committee may grant options under the 1990 Plan and 
determine the terms of options granted to key employees.  The Board selects 
the members of the Compensation Committee from among disinterested members of 
the Board. Members of the Compensation Committee serve at the will of the 
Board and may be removed from the Compensation Committee at any time at the 
Board's discretion. 

AMENDMENT OF THE 1990 PLAN

     The 1990 Plan provides that the Board may from time to time discontinue 
or further amend the 1990 Plan without the consent of the participants or the 
Company's stockholders.  Additionally, the Board may amend the 1990 Plan in 
order for stock options to qualify for the exemption under Rule 16b-3 or to 
qualify as "performance-based" compensation under Section 162(m). 

CERTAIN FEDERAL INCOME TAX ASPECTS

     The following is a summary of the principal federal income tax 
consequences associated with grants of options under the 1990 Plan.  It does 
not describe all federal income tax consequences under the 1990 Plan, nor 
does it describe foreign, state or local tax consequences.  Each participant 
is urged to consult his or her personal tax advisor to determine the specific 
tax consequences to him or her of the 1990 Plan.

     NONQUALIFIED STOCK OPTIONS.  The 1990 Plan is not a "qualified plan" 
within the meaning of Section 401 of the Code.  The granting of a 
nonqualified stock option will not result in federal income tax consequences 
to either the Company or the optionee.  Upon exercise of a nonqualified stock 
option, the optionee will recognize ordinary income in an amount equal to the 
difference between the fair market value of the shares on the date of 
exercise and the exercise price, and the Company will be entitled to a 
corresponding deduction.

     For purposes of determining gain or loss realized upon a subsequent sale 
or exchange of such shares, the optionee's tax basis will be the sum of the 
exercise price paid and the amount of ordinary income, if any, recognized by 
the optionee.  Any gain or loss realized by an optionee on disposition of 
such shares generally will be a long-term capital gain or loss (if the shares 
are held as a capital asset for at least one year) and will not result in any 
tax deduction to the Company. 

     INCENTIVE STOCK OPTIONS.  In general, no income will be recognized by an 
optionee and no deduction will be allowed to the Company at the time of the 
grant or exercise of an incentive stock option granted under the 1990 Plan. 
When the stock received on exercise of the option is sold, provided that the 
stock is held for more than two years from the date of grant of the option 
and more than one year from the date of exercise, the optionee will recognize 
long-term capital gain or loss equal to the difference between the amount 
realized and the exercise price of the option related to such stock.  If 
these holding period requirements under the Code are not satisfied, the 
subsequent sale of stock received upon exercise of an incentive stock option 
is treated as a "disqualifying disposition."  In general, the optionee will 
recognize taxable income at the time of a disqualifying disposition as 
follows: (i) ordinary income in an amount equal to the excess of the lesser 
of the fair market value of the Common Stock on the date the incentive stock 
option is exercised or the amount realized on such disqualifying disposition 
over the exercise price and (ii) capital gain to the extent of any excess of 
the amount realized on such disqualifying disposition over the fair market 
value of the Common Stock on the date the incentive stock option 

                                     -14- 
<PAGE>

is exercised (or capital loss to the extent of any excess of the exercise 
price over the amount realized on disposition).  Any capital gain or loss 
recognized by the optionee will be long-term or short-term depending upon the 
holding period for the stock sold.  The Company may claim a deduction at the 
time of the disqualifying disposition equal to the amount of the ordinary 
income the optionee recognizes.

     Although an optionee will not realize ordinary income upon the exercise 
of an incentive stock option, the excess of the fair market value of the 
shares acquired at the time of exercise over the option price is included in 
"alternative minimum taxable income" for purposes of calculating the 
optionee's alternative minimum tax, if any, pursuant to Section 55 of the 
Code.

     WITHHOLDING.  Withholding of federal income taxes at applicable rates 
will be required in connection with any ordinary income realized by a 
participant by reason of the exercise of stock options granted pursuant to 
the 1990 Plan.  A participant must pay such taxes to the Company in cash or 
Common Stock prior to the receipt of any Common Stock certificates.

     THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE PROPOSAL TO APPROVE 
THE AMENDMENTS TO THE 1990 PLAN.

     EMPLOYMENT AGREEMENTS

     The Company has entered into employment agreements with Messrs. Owens, 
Brindley and Sheen, all of which are substantially on the terms described 
below.  These employment agreements provide that they expire January 31, 1993,
but are subject to automatic yearly extensions except in certain events.  Among
other provisions, these agreements provide that, in consideration for remaining
in the employ of the Company, each such officer is entitled to receive certain
benefits, subject to certain conditions.

     If an officer of the Company is terminated for a reason other than (a) 
his death, disability or retirement, (b) for cause or (c) his voluntary 
termination other than for good reason, such officer would be entitled to 
receive from the Company a lump sum severance payment equal to the sum of the 
following amounts: (i) the officer's full base salary through his date of 
termination at the rate then in effect, (ii) an amount equal to two times the 
officer's annual base salary, (iii) certain relocation and indemnity 
payments, along with all legal fees and expenses incurred by the officer as a 
result of the termination and (iv) in the event the officer is subject to the 
excise tax imposed by Section 4999 of the Code, as a result of a change in 
control, an amount equal to the product of (a) 25% multiplied by (b) the 
amount of any "excess parachute payment" received by the officer as described 
in the provisions of Section 280G(b) of the Code.  In the event that an 
officer receives a "parachute  payment" as the result of a change in control, 
such payment would be deemed to be an "excess parachute payment" if it equals 
or exceeds 300 percent of the officer's "base amount," generally the average 
annual compensation received by the officer over the most recent five tax 
years.  The "excess parachute payment" is computed as that portion of the 
"parachute payment" which exceeds the "base amount."  In addition, unless the 
officer is terminated for cause, the Company must maintain in full force and 
effect for the continued benefit of the officer for a two-year period after 
the date of termination all benefit plans and programs or arrangements in 
which the officer was entitled to participate immediately prior to the date 
of termination.

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

     The Input/Output, Inc. Supplemental Executive Retirement Plan
(the "SERP") was established in 1992.  The SERP is designed to defer
taxation of participants until their receipt of benefits.  The Board,
in its sole discretion, is authorized to determine eligibility for
participation in the SERP.  The Board has appointed a committee
composed of directors and executive officers of the Company to
administer the SERP.  The SERP provides to each participant, upon such
participant's retirement from the Company at age 65, an annual
deferred benefit equal to 60% of the participant's average annual
compensation for those three consecutive calendar years during his
employment that results in the highest annual compensation, reduced by
certain social security benefits and certain actuarial equivalents of
annual matching contributions made by the Company and credited to the
participant under the Company's Section 401(k) Plan.  If a participant
terminates employment prior to his 65th birthday due to death, total
disability or early retirement that is approved by the Board, the
participant will be 50% vested in his deferred benefit upon attaining
age 55 and completing 15 years of service with the Company.  A
participant's vested interest increases 5% thereafter for each
additional year of service.  A participant is fully vested in his
deferred benefit at age 65, or at age 55 if the participant has
completed 25 years of service with the Company, or upon total
disability of the participant or a change in control of the Company. 
In addition, the SERP provides that the Company shall pay a
participant an amount equal to any excise tax pursuant to Section 280G
of the Code in the event that payment of a deferred benefit results in
liability for such tax.

     "Change of control" for purposes of the SERP is defined to
include the following: (i) mergers or consolidations in which the
Company is not the surviving corporation (unless the proportionate
ownership of the Company's stockholders in the surviving corporation
is unchanged), (ii) any sale or other disposition of all or
substantially all of the Company's assets, (iii) the approval by the
Company's stockholders of any plan of liquidation or dissolution, (iv)
the acquisition by a third party of beneficial ownership of 50.1% of
the Company's outstanding voting securities and (v) during any two-
year period, persons who constituted at least a majority of the entire
Board of Directors at the beginning of such period cease for any
reason (other than death) to constitute a majority of the directors,
unless the new director was approved by at least two-thirds of the
directors then still in office who were directors at the beginning of
such period.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors (the "Committee") 
includes only directors who are not employees of the Company.  The Committee 
establishes the salary levels of corporate officers and administers the 
Company's stock option and management incentive plans.  During fiscal 1996 
the Committee was comprised of G. Thomas Graves III, Chairman, Shelby H. 
Carter, Jr. and Glen H. Denison. The following report presents the Committee's
summary of the Company's compensation programs and policies and describes the 
bases for compensation of the Company's executive officers and its chief 
executive officer:

     COMPENSATION POLICY

     The goal of the Company's executive compensation policy is to support 
the overall objective of enhancing stockholder value, while at the same time 
attracting, motivating and retaining highly qualified and productive 
employees.  It is the policy of the Company that a significant portion of the 
compensation paid to the executive officers should be based on the Company's 
results of operations and the growth in value of its equity.  This policy 
aligns the interests of the Company's management and stockholders by placing 
increased emphasis on performance-based pay and reduced emphasis on fixed pay 
in overall total compensation.  To achieve its goals, the Company's executive 
compensation policies have been designed to provide competitive levels of 
compensation that integrate annual base compensation with bonuses based upon 
corporate performance and individual initiatives and performance.  Also, 
since 1990, the  Company has adopted and 


                                   -22-
<PAGE>

maintained stock option plans under which the benefits realized by executives 
are directly related to stock price performance. Consistent with this objective,
the Company has had in place for a number of years the Input/Output, Inc. 
Management Incentive Plan (the "MIP") that established annual cash bonuses to
the officers and other key employees of the Company, which were tied to actual
profits performance compared to budgeted and prior year's pretax profits.

     In its assessment of compensation levels, the Committee takes into 
consideration performance relative to the individual responsibilities of the 
executive officers, as well as the financial performance of the Company 
relative to its goals and relative to the financial performance of other 
companies.  The Committee also considers the competitiveness of both the 
entire executive compensation package and each of its individual components.  
To assist it in its consideration, the Committee periodically engages the 
services of outside compensation consultants to evaluate the Company's 
executive compensation structure from time to time.  These consultants report 
directly to the Committee and advise the Committee regarding the competitiveness
of the Company's executive compensation package as well as recent trends and 
developments in executive compensation for U.S. companies.  In this regard, 
during fiscal 1996, the Committee engaged the services of William M. Mercer Co.
as independent compensation consultants to review and make recommendations to 
the Committee in these areas.

     As a result of the Committee's review of the Company's total compensation
program for its executives, the Committee recommended to the Board of Directors
in July 1996 that the Company adopt the Input/Output, Inc. 1996 Management 
Incentive Program (the "Incentive Plan") to replace the MIP.  The Incentive Plan
adopted by the Board of Directors, which is subject to stockholder approval at 
the Annual Meeting, is similar to the MIP regarding its calculation of bonuses 
by reference to objective performance criteria.  The terms of the Incentive Plan
are included with this Proxy Statement as Appendix II, and certain significant 
features of the plan are described elsewhere in this Proxy Statement.

     The Committee has considered the impact of Section 162(m) regarding the 
corporate limitations on deducting certain compensation expenses.  It is the 
Committee's intent to adopt policies to obtain maximum tax deductibility of 
executive compensation, consistent with providing motivational and competitive
compensation which is truly performance-based.  In furtherance of this goal, 
the Incentive Plan and amendments to the Amended and Restated 1990 Stock 
Option Plan have been proposed for stockholder approval in order to assure 
that the Company's executive compensation plans meet the requirements of 
Section 162(m) to achieve maximum deductibility of executive compensation 
expense.  See "Proposal to Approve the Input/Output, Inc. 1996 Management 
Incentive Program" and "Proposal to Approve Amendments to the Input/Output, 
Inc. Amended and Restated 1990 Stock Option Plan."

     The Committee reviews the performance of the Company and each officer 
individually to determine salary and bonus adjustments and to determine stock 
option awards.  In determining appropriate salary levels, the Committee 
generally considers compensation levels for executive positions with similar 
duties and responsibilities in the external market, including those at 
comparable-sized electronics companies, as well as corporate and individual 
performance.

     Company executive compensation currently consists of two key elements: A 
long-term component (stock options) and an annual component (base salary and 
bonus).  Following is a description of the elements of the Company's current 
executive compensation program and how each relates to the objectives and 
policies outlined above.

     STOCK OPTIONS.  The Committee believes that long-term incentives should 
be provided to management to increase shareholder value, as measured by stock 
price.  The Committee believes that stock incentives are appropriate, not only
for senior management, but also for key employees of the Company and its 
subsidiaries.


                                   -23-

<PAGE>

All options provide for the purchase of shares at an exercise price 
equal to fair market value on the date of grant.  See "Proposal to 
Approve Amendments to the Input/Output, Inc. Amended and Restated 1990 
Stock Option Plan."

     MANAGEMENT INCENTIVE PLAN.  The Committee believes that key
employees should have a significant portion of their total
compensation based on the Company's relative financial performance to
plan projections and the prior year's results.  The participant's
annual cash bonus under the proposed Incentive Plan is determined
based on specified performance achievements by the Company.

     Each participant is assigned to a group within the Incentive Plan
which reflects his responsibility level within the Company.  The
performance criteria for Incentive Plan groups emphasize the Company's
objective for growth in profits before tax compared to budgeted pretax
earnings for the plan year and the actual pretax results for the prior
year.  See "Proposal to Approve the Input/Output, Inc. 1996 Management
Incentive Program."

     BASE SALARY.  The Committee approves the annual salaries for all
officers of the Company.  The Committee reviews recommendations made
by the Chief Executive Officer with regard to salary adjustments for
officers other than himself, and then either approves or changes these
recommended salary adjustments.  The Committee independently reviews
performance of the Chief Executive Officer and determines an
appropriate salary based on the criteria set forth above.  As noted
above, base salaries for the Company's executive officers are also
determined by reference to salary surveys from outside consultants and
other sources.

     In previous years, certain executive officers were awarded grants
of restricted stock under the Company's restricted stock plan adopted
in 1990.  The Committee believes that these grants served their
purpose at such times increasing the share ownership of key
executives, providing an emphasis on maintaining and enhancing
stockholder value and retaining the executives during important
developmental years of the Company's growth.  All shares reserved for
grant under the plan have been awarded, and the Committee does not
intend to implement another restricted stock plan in the foreseeable
future.

     COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

     In July 1996, Mr. Owens' annual base salary was increased from
$300,000 to $350,000 in recognition of his responsibility for the
Company's revenue growth and earnings performance.  In June 1996, the
Committee awarded a bonus of $ 306,526 to Mr. Owens pursuant to the
MIP.  In making this award, the Committee noted that the Company's
performance objectives for fiscal 1996 (in accordance with the terms
of the MIP) had been exceeded.  Mr. Owens' participation in total
option grants made by the Company during fiscal 1996 under the 1990
Stock Option Plan was based upon overall compensation packages and
option plans provided to senior executives in similar companies as
well as Mr. Owens' level and scope of responsibilities and
contributions to the Company during fiscal 1996.  Based on these
criteria, in August  1995, the Committee awarded options to purchase
200,000 shares of Common Stock under the Amended and Restated 1990
Stock Option Plan to Mr. Owens.

     SUMMARY

     The Committee believes that the Company's executive compensation
policies and programs serve the interests of the stockholders and the
Company effectively.  The various compensation programs are believed
appropriately balanced to provide motivation for executives to
contribute to the Company's overall success and enhance the value of
the Company for the stockholders' benefit.  As in past years, when
performance goals are met or exceeded, resulting in increased value to
stockholders, executives will be rewarded 


                                 -24-

<PAGE>

commensurately.  In the aggregate, 50.5% of  the Named Executive 
Officers' cash compensation for fiscal 1996 was derived from incentives 
directly linked to corporate performance.  Mr. Owens received 52% of his 
cash compensation from incentives.  The Committee will continue to 
monitor the effectiveness of the Company's total compensation program 
and continue to make proposals where applicable, to meet the current and 
future needs of the Company.

COMPENSATION OF DIRECTORS

     As compensation for serving on the Company's Board of Directors,
each director who is not an employee of the Company receives $1,500
for each meeting attended and $1,500 for each committee meeting
attended.  In addition, each non-employee director receives an annual
stipend of $20,000.

     DIRECTORS RETIREMENT PLAN.  During June 1992, the Company adopted
the Directors Retirement Plan.  Under the Directors Retirement Plan,
participation was limited to directors who served as outside directors
for an aggregate of not less than five years or whose service on the
Board as an outside director terminated due to death or disability or
a change in control of the Company.  Payment of benefits under the
Directors Retirement Plan is payable in quarterly installments and
commences at the beginning of the Company's fiscal quarter next
following the later date at which a director (i) attains age sixty-
five or (ii) retires from the Board.  Payments of benefits shall
continue for a period equal to the lesser of (a) the number of years
and portions thereof, rounded upwards to the nearest six months,
during which such director served as an outside director or (b) ten
years.  (During fiscal 1996, the Board determined to accelerate the
vesting in full of Mr. Selecman's years of service as an outside
director.)  In the event of a "change of control" (as defined in the
Plan), the director may elect to receive a lump sum payment
representing the present value of the quarterly payments otherwise
payable.  Total benefits payable to an outside director under the
Directors Retirement Plan are equal 


                                   -25-

<PAGE>

to the greater of (i) 100% of the outside director's annual stipend effective 
for the fiscal year in which he retires or (ii) 100% of the outside 
director's annual stipend payable in the fiscal year prior to retirement.

     In July 1996, the Board of Directors of the Company determined to 
discontinue the Directors Retirement Plan.  Under the terms adopted by the 
Board, all benefit accruals relating to years of service through the date of 
discontinuation were frozen; in addition, participation by any individuals 
not currently an outside director was prohibited.

     OUTSIDE DIRECTORS' STOCK OPTION PLANS.  Pursuant to the Amended and 
Restated 1991 Outside Directors Stock Option Plan (the "1991 Plan"), the 
Company is authorized to make automatic grants of options to purchase shares 
of Common Stock to outside directors.  On October 1, 1996, each outside 
director is entitled under the terms of the 1991 Plan to an option grant for 
30,000 shares.  Under the terms of the 1991 Plan, the purchase price  per 
share under each option must be not less than 100% of the fair market value 
of the shares of Common Stock on the date of grant and the option periods 
cannot be more than 10 years from the date the option is granted.  Options 
granted under the 1991 Plan become exercisable one year following the date of 
the grant with respect to 25% of the shares of Common Stock covered thereby. 
Additional 25% increments become exercisable, cumulatively, on the next 
succeeding anniversary dates from the date of grant, until four years from 
the date of the grant, at which time the options may be exercised in full.  
The 1991 Plan also permits the exercise of options by the delivery of shares 
of Common Stock previously owned by the optionees in lieu of or in addition 
to cash.  The exercisability of the options accelerates upon a change of 
control (as described in the plan) and upon the option holder's death while 
serving as a director or upon termination as a director as the result of 
retirement or disability.  As of August 31, 1996, the Company had granted 
options covering a total of 804,000 shares of Common Stock under the 1991 
Plan.

     On October 1, 1996, the last grants of stock options under the 1991 Plan 
will be made to the Company's outside directors, and no further shares will 
be available for grant under the 1991 Plan.  In order that the Company might 
provide a means for grants of stock options to its outside directors and to 
attract, recruit and retain qualified outside directors to serve the Company, 
the Board of Directors of the Company adopted, subject to stockholder 
approval, the Input/Output, Inc. 1996 Non-Employee Director Stock Option Plan 
(the "Directors' Plan"), effective as of July 12, 1996.   See "Proposal 
to Adopt the Input/Output, Inc. 1996 Non-Employee Director Stock Option Plan."

will participate in the Budget Bonus, the Corporate Threshold with respect to
the Budget Bonus for such Bonus Year, and the
 
                                       3
<PAGE>
Performance Goals with respect to each participating Group. The Corporate
Threshold with respect to the Budget Bonus for any particular Bonus Year shall
be an amount equal to (i) the Budgeted Profits Before Taxes, multiplied by (ii)
a percentage determined by the Committee; provided that such Corporate Threshold
shall not be less than an amount equal to 80% of Budgeted Profits Before Taxes.
The actual percentage amounts of the Performance Goals to apply with respect to
the Base Salaries of Participants in each Group will be determined by reference
to the extent of the amount that the Profits Before Taxes exceeds the Corporate
Threshold for the Budget Bonus for that Bonus Year; provided that the maximum
Budget Bonus that may be received by a Participant may not exceed twenty-five
percent (25%) of such Participant's Base Salary for such Bonus Year.

shall set forth in writing the key employees designated as Participants for the
Bonus Year and their appropriate Group, whether that Group will participate in
the PBT Bonus, the Corporate Threshold with respect to the PBT Bonus for such
Bonus Year, and the Performance Goals with respect to each participating Group.
The Corporate Threshold with respect to the PBT Bonus for any particular Bonus
Year shall be not less than the amount of the Profits Before Taxes for the
immediately preceding Bonus Year in question. The actual percentage amounts of
the Performance Goals to apply with respect to the Base Salaries of Participants
in each Group for purposes of determining a PBT Bonus will be determined by
reference to the extent of the amount that the Profits Before Taxes exceeds the
Corporate Threshold for the PBT Bonus for that Bonus Year.
 
                                  ARTICLE VII
                   PAYMENT OF BONUSES AND GENERAL PROVISIONS
 
    7.1  LIMITATION ON TOTAL BONUS.  Notwithstanding any provision to the
contrary contained herein, the maximum Total Bonus payable to any Participant
with respect to any Bonus Year shall not exceed $750,000. The Bonus amounts
calculated in accordance with Articles V and/or VI hereof for any Participant
who is a Covered Employee with respect to the Bonus Year in question may be
reduced by an amount of up to 50% by the Committee in its sole discretion;
PROVIDED, HOWEVER, that under no circumstances may the amount of a Bonus
determined under Articles V and/or VI of this Plan with respect to any
Participant who is a Covered Employee with respect to the Bonus Year in question
be increased. Bonus amounts calculated hereunder with respect to any Participant
who is not a Covered Employee for the Bonus Year in question may be reduced or
increased by the Committee in its sole discretion.
 
    7.2  PAYMENT.  As a condition to eligibility for payment of a Bonus with
respect to any particular Bonus Year, a Participant shall be required to be in
the employ of the Company or one of its Subsidiaries through the applicable
Payment Date, UNLESS (i) such Participant terminated his or her employment
during such period due to retirement from the Company and its Subsidiaries in
accordance with standard retirement policies of the Company and its Subsidiaries
then in effect, or (ii) the Participant, while in the employ of the Company or
one of its Subsidiaries, became totally and permanently disabled (as that term
is defined in Section 22(e) of the Code) or died during such period. In the
event of such retirement, death or disability, the Participant (or, in the case
of death or disability, the Participant's estate or legal representative, as the
case may be, or a designated beneficiary in accordance with Section 11.6) shall
receive a prorated portion of his Bonus based on the portion of the Bonus Year
that the Participant was in the employ of the Company or one of its
Subsidiaries.
 
    In the event that a person becomes an employee of the Company or one of its
Subsidiaries during a Bonus Year and the Committee determines to designate such
person as a member of Group III or Group IV (or their successor Group(s), if
subsequently designated by the Committee in accordance with Article IV), such
person will become a Participant as of the date of each designation, and shall
be
 
                                       4
<PAGE>
entitled to receive a prorated portion of his Bonus based on the portion of the
Bonus Year that the Participant was in the employ of the Company or one of its
Subsidiaries. If a Participant that is a member of Group I or Group II (or their
successor Group(s), if designated by the Committee) ceases to be employed by the
Company or such Participant's status with the Company as an officer changes as a
result of a reassignment of duties, any person who succeeds the Participant in
the same or a comparable position within the Company, may be designated by the
Committee as a Participant and a member of Group I or Group II (or their
successor(s)), as may be applicable, for the duration of the applicable Bonus
Year, effective as of the date such person assumes such position.
 
    Following the verification by the Company's independent accountants of the
Company's financial results for any Bonus Year, the Committee shall certify (i)
whether the Profits Before Taxes exceeded the Corporate Thresholds for the
Budget Bonus and the PBT Bonus; (ii) whether and the extent to which PBT Bonuses
and Budget Bonuses are payable to the Participants in each Group by applying
their applicable Performance Goals to their respective Base Salaries; and (iii)
the amounts of the Bonuses, if any, to be paid to the Participants in accordance
with Articles V and VI, as may be applicable (and Section 7.1, if applicable).
The Committee shall instruct the Company, or instruct the Company to cause any
Subsidiary, as applicable, to pay to each Participant his Bonus in accordance
with this Article, as promptly as reasonably practicable after such Payment
Date.
 
    7.3  PARTIAL FISCAL YEARS.  In the event that the Company and its
Subsidiaries adopt any different fiscal year which results in a fiscal year
having less than twelve months, the Committee shall, in its sole discretion,
award Bonuses computed as provided in Articles V and VI (and Section 7.1, if
applicable) but reduced by the Committee for such shortened fiscal year, or
defer any awards of Bonuses for such fiscal period until a Payment Date
following such full twelve-month fiscal year.
 
    7.4  NO RIGHTS TO BONUS.  The prospective recipient of a Bonus shall not
have any rights with respect to any Bonus, or any portion thereof, until the
award thereof on the Payment Date to which the particular Bonus amount relates.
 
                                  ARTICLE VIII
 
                          AMENDMENT OR DISCONTINUANCE
 
    The Committee may at any time and from time to time, without the consent of
the Participants, alter, amend, revise, suspend, or discontinue the Plan in
whole or in part; provided that any amendment that modifies any preestablished
performance goal for Participants in Group I or Group II (or their successor(s),
as may be applicable) under this Plan with respect to any particular Bonus Year
may only be effected on or prior to that date which is 90 days following the
commencement of such Bonus Year. In addition, the Board shall have the power to
amend the Plan in any manner advisable in order for Bonuses granted under the
Plan to qualify as "performance-based" compensation under Section 162(m) of the
Code (including amendments as a result of changes to Section 162(m) or the
regulations thereunder to permit greater flexibility with respect to Bonuses
granted under the Plan).
 
                                   ARTICLE IX
 
                               EFFECT OF THE PLAN
 
    Neither the adoption of this Plan nor any action of the Board or the
Committee shall be deemed to give any Participant any right to be granted a
Bonus or any other rights. In addition, nothing contained in this Plan and no
action taken pursuant to its provisions shall be construed to (a) give any
Participant any right to any compensation, except as expressly provided herein;
(b) be evidence of any agreement, contract or understanding, express or implied,
that the Company will employ a Participant in any particular position; (c) give
any Participant any right, title, or interest whatsoever in or to any
investments which the Company may make to aid it in meeting its obligations
hereunder; or (d) create a trust of any kind or a fiduciary relationship between
the Company and a Participant or any other person.

    The effective date of this Plan shall be as of July 12, 1996, subject to
stockholder approval. This Plan and any benefits granted hereunder shall be null
and void if stockholder approval is not obtained at the next annual meeting of
stockholders of the Company. Unless sooner terminated by action of the Board,
the Plan will terminate on the 12th day of July, 2001.
 
                                   ARTICLE XI
 
                            MISCELLANEOUS PROVISIONS
 
    11.1  NO RIGHT TO CONTINUE EMPLOYMENT.  Nothing in the Plan confers upon any
Participant the right to continue in the employ of the Company or interferes
with or restricts in any way the right of the Company to discharge any employee
at any time (subject to any contract rights of such employee).
 
    11.2  TAX REQUIREMENTS.  The Company (and, where applicable, its
Subsidiaries) shall have the power and the right to deduct or withhold, or
require a Participant to remit to the Company, an amount sufficient to satisfy
applicable taxes required by law to be withheld with respect to any payment of
any Bonus to a Participant.
 
    11.3  INDEMNIFICATION OF BOARD AND COMMITTEE.  No member of the Committee,
nor any officer, employee or agent of the Company acting on behalf of the
Committee, shall be personally liable for any action, determination, or
interpretation taken or made in good faith with respect to the Plan, and all
members of the Committee and each and every officer, employee or agent of the
Company acting on their behalf shall, to the fullest extent permitted by law, be
fully indemnified and protected by the Company in respect of any such action,
determination or interpretation. Each member of the Committee shall, in the
performance of his or her duties under the Plan, be fully protected in relying
in good faith upon the financial statements of the Company as contemplated by
the terms of the Plan.
 
    11.4  EFFECT ON PARTICIPATION.  The award of a Bonus to a Participant shall
not by itself be deemed either to entitle the Participant to, or to disqualify
the Participant from, as the case may be, participation in any other future
grant of Bonuses under the Plan or otherwise, or in any other compensation or
benefit plan of the Company or any of its Subsidiaries currently existing or
hereafter established.
 
    11.5  OTHER COMPENSATION AGREEMENTS.  Nothing contained in this Plan shall
prevent the Board from adopting other or additional compensation arrangements,
subject to stockholder approval if such approval is required; and such
arrangements may be either generally applicable or applicable only in specific
cases.
 
    11.6  APPLICABILITY TO SUCCESSORS.  The Plan shall be binding upon and inure
to the benefit of the Company and each Participant, the successors and assigns
of the Company, and the beneficiaries, personal representatives and heirs of
each Participant. Any interests of Participants under the Plan may not be
voluntarily sold, transferred, alienated, assigned or encumbered, other than by
will or pursuant to the laws of descent and distribution; provided however, that
a Participant may designate a beneficiary or beneficiaries to receive payments
after the Participant's death, by written notice to the Committee. If the
Company becomes a party to any merger, consolidation or reorganization, the Plan
shall remain in full force and effect as an obligation of the Company or its
successors in interest.
 
    11.7  REORGANIZATION, MERGER OR CONSOLIDATION.  In the event of a merger,
consolidation, sale of assets, reorganization or other business combination in
which the Company is not the surviving or continuing corporation, or pursuant to
which shares of the Company's Common Stock would be converted into cash,
securities or other property (other than a merger of the Company in which the
holders of the Company's Common Stock immediately prior to the merger have the
same proportionate ownership of Common Stock of the surviving corporation
immediately after the merger), the Bonus Year will be deemed to have ended on
the date such transaction is consummated. PBT Bonus
 
                                       6
<PAGE>
calculations will be determined based on the Bonus Year-to-date profits before
taxes and will be determined based on a comparison of (i) profits before taxes
for such Bonus Year to the date of the event, to (ii) profits before taxes for
the immediately preceding fiscal year to the same date of such preceding year.
The Budget Bonus calculations will be determined based on a comparison of (x)
profits before taxes for such Bonus Year to the date the transaction is
consummated, to (y) Budgeted Profits Before Taxes for such Bonus Year, pro-rated
to the date the transaction is consummated. Such calculations will be based upon
the Company's consolidated statement of earnings for the month ended immediately
prior to the date of consummation of the sale, merger, reorganization or
business combination.
 
    11.8  GENDER AND NUMBER.  Where the context permits, words in the masculine
gender shall include the feminine and neuter genders, the plural form of a word
shall include the singular form, and the singular form of a word shall include
the plural form.
 
    11.9  STOCKHOLDER VOTE.  The material terms of this Plan shall be disclosed
to the stockholders of the Company for approval in accordance with Section
162(m) of the Code. No award or payment of any Bonus under this Plan shall made
unless such stockholder approval is obtained.
 
                                  ARTICLE XII
 
                            UNFUNDED STATUS OF PLAN
 
    The Plan is intended to constitute an "unfunded" plan for incentive
compensation. With respect to any Bonuses granted but not yet paid to a
Participant by the Company, nothing contained herein shall give any such
Participant any rights that are greater than those of a general unsecured
creditor of the Company.

    4.2  GRANT OF STOCK OPTIONS.  On the first business day of November 1996,
each person who is a then a Non-Employee Director shall be granted a
Nonqualified Stock Option to purchase 20,000 shares of Common Stock. Thereafter,
on the first business day of November 1997, each such Non-Employee Director
shall be granted a Nonqualified Stock Option to purchase 10,000 shares and on
the first business day of November 1998, each such Non-Employee Director shall
be granted a Nonqualified Stock Option to purchase 10,000 shares.
 
    With respect to any Non-Employee Director who joins the Board after the
first business day of November 1996, on that date on which such person is first
elected or otherwise commences serving as a Non-Employee Director, such person
shall be granted a Nonqualified Stock Option to purchase 20,000 shares.
Thereafter, on the first business day of the immediately succeeding November

November immediately succeeding the date that such 10,000-share Stock Option was
granted, such Non-Employee Director shall be granted an additional Nonqualified
Stock Option to purchase 10,000 shares.
 
    The first grant of a Nonqualified Stock Option for 20,000 shares pursuant to
this Section 4.2 is herein referred to as the "First Grant"; the second grant
and third grant of Nonqualified Stock Options for 10,000 shares each pursuant to
this Section 4.2 is herein referred to as the "Second Grant" and the "Third
Grant," respectively.
 
    Each grant of Stock Options shall be evidenced by a stock option agreement
setting forth the number of shares subject to the Stock Option, the option
exercise price, the option period of the Stock Option, and such other terms and
provisions as, except to the extent permitted herein, are not inconsistent with
the Plan.

less than the par value per share of the Common Stock.
 
    4.4  VESTING; OPTION PERIOD.  Each Stock Option shall vest and be
exercisable as follows: The First Grant Stock Options shall vest in 33.33%
installments on the first, second and third anniversary dates of the First
Grant; the Second Grant Stock Options shall vest in 50% installments on the
first

and second anniversary dates of the Second Grant; and the Third Grant Stock
Options shall be fully exercisable on and after the first anniversary date of
the Third Grant. In no event shall the period of time during which a
Nonqualified Stock Option may be exercised exceed ten years from the Date of
Grant of the Stock Option in question. No Stock Option may be exercised at any
time after the expiration of its option period. A Stock Option, or portion
thereof, may be exercised in whole or in part only with respect to whole shares
of Common Stock.

made in cash or by the Participant's delivery to the Company of shares of Common
Stock which have a Fair Market Value equal to the exercise price (or in any
combination of cash and shares of Common Stock having an aggregate Fair Market
Value equal to the exercise price). No shares may be issued until full payment
of the purchase price therefor has been made, and a Participant will have none
of the rights of a stockholder until shares are issued to him. Additionally,
shares covered by a Stock Option may be purchased upon exercise, in whole or in
part, in accordance with the applicable stock option agreement, by authorizing a
third party to sell the shares (or a sufficient portion thereof) acquired upon
exercise of a Stock Option, and assigning the delivery to the Company of a
sufficient amount of the sale proceeds to pay for all the shares acquired
through such exercise and any tax withholding obligations resulting from such
exercise.

    In the event a Participant shall cease to serve in his capacity as a
director of the Company for any reason other than death, disability or
retirement pursuant to Company policies, such Participant's Stock Options may be
exercised by the Participant for a period of one hundred eighty (180) days after
the Participant's termination of service, or until expiration of the applicable
Option Period (if sooner), to the extent of the shares with respect to which
such Stock Options could have been exercised by the Participant on the date of
termination, and thereafter to the extent not so exercised, such Stock Options
shall terminate. In addition, a Participant's Stock Options may be exercised as
follows in the event of such Participant's death, disability or retirement:
 
        (a)  DEATH.  In the event of death while serving as a director, all
    unmatured installments of Stock Options outstanding shall thereupon
    automatically be accelerated and become fully vested and exercisable in
    full, and the Stock Option may be exercised for a period of twelve (12)
    months after the Participant's death or until expiration of the Stock Option
    period (if sooner), by the Participant's estate or personal representative,
    or by the person who acquired the right to exercise the Stock Option by
    bequest or inheritance or by reason of the Participant's death; and
 
        (b)  DISABILITY OR RETIREMENT.  In the event of termination of service
    as a director as the result of a total and permanent disability (as defined
    in Section 22(e) of the Code) or retirement as a director pursuant to
    standard Company policies applicable to directors, then all unmatured
    installments of Stock Options outstanding shall thereupon automatically be
    accelerated and become fully vested and exercisable in full, and the Stock
    Option may be exercised by the Participant or his guardian or legal
    representative for a period of twelve (12) months after such termination or
    until expiration of the Stock Option period (if sooner).
 
                                  ARTICLE VII
 
                          AMENDMENT OR DISCONTINUANCE
 
    The Board may at any time and from time to time, without the consent of the
Participants, alter, amend, revise, suspend, or discontinue the Plan in whole or
in part.
 
                                       4

    In addition, the Board shall have the power to amend the Plan in any manner
advisable in order for Stock Options granted under the Plan to qualify for the
exemption provided by Rule 16b-3 (or any successor rule relating to exemption
from Section 16(b) of the 1934 Act), including amendments as a result of changes
to Rule 16b-3 or the regulations thereunder to permit greater flexibility with
respect to Stock Options granted under the Plan, and any such amendment shall,
to the extent deemed necessary or advisable by the Committee, be applicable to
any outstanding Stock Options theretofore granted under the Plan,
notwithstanding any contrary provisions contained in any stock option agreement.
In the event of any such amendment to the Plan, the holder of any Stock Option
outstanding under the Plan shall, upon request of the Committee and as a
condition to the exercisability thereof, execute a conforming amendment in the
form prescribed by the Committee to any stock option agreement relating thereto
within such reasonable time as the Committee shall specify in such request.
Notwithstanding anything contained in this Plan to the contrary, unless required
by law, no action contemplated or permitted by this Article VII shall adversely
affect any rights of Participants or obligations of the Company to Participants
with respect to any Stock Options theretofore granted under the Plan without the
consent of the affected Participant.
 
                                  ARTICLE VIII
 
                               EFFECT OF THE PLAN
 
    Neither the adoption of this Plan nor any action of the Board or the
Committee shall be deemed to give any director any right to be granted a Stock
Option to purchase or receive Common Stock of the Company or any other rights
except as may be evidenced by a stock option agreement, or any amendment
thereto, duly authorized by and executed on behalf of the Company and then only
to the extent of and upon the terms and conditions expressly set forth therein.
 
                                   ARTICLE IX
 
                                      TERM
 
    The Plan shall be submitted to the Company's stockholders for their
approval. Unless sooner terminated by action of the Board, the Plan will
terminate on the 12th day of July, 2006. Stock Options under the Plan may not be
granted after that date, but Stock Options granted before that date will
continue to be effective in accordance with their terms and conditions.

                              CAPITAL ADJUSTMENTS
 
    If at any time while the Plan is in effect or unexercised Stock Options are
outstanding there shall be any increase or decrease in the number of issued and
outstanding shares of Common Stock through the declaration of a Stock Dividend
or through any recapitalization resulting in a stock split-up, combination, or
exchange of shares of Common Stock, then and in such event:
 
        (i) An appropriate adjustment shall be made in the maximum number of
    shares of Common Stock then subject to being awarded under grants pursuant
    to the Plan, to the end that the same proportion of the Company's issued and
    outstanding shares of Common Stock shall continue to be subject to being so
    awarded; and
 
        (ii) Appropriate adjustments shall be made in the number of shares of
    Common Stock and the exercise price per share thereof then subject to
    purchase pursuant to each such Stock Option previously granted and
    unexercised, to the end that the same proportion of the Company's issued and
    outstanding shares of Common Stock in each instance shall remain subject to
    purchase at the same aggregate exercise price.
 
    Any fractional shares resulting from any adjustment made pursuant to this
Article X shall be eliminated for the purposes of such adjustment. Except as
otherwise expressly provided herein, the
 
                                       5

issuance by the Company of shares of its capital stock of any class, or
securities convertible into shares of capital stock of any class, either in
connection with direct sale or upon the exercise of rights or warrants to
subscribe therefor, or upon conversion of shares or obligations of the Company
convertible into such shares or other securities, shall not affect, and no
adjustment by reason thereof shall be made with respect to, the number of or
exercise price of shares of Common Stock then subject to outstanding Stock
Options granted under the Plan.
 
                                   ARTICLE XI
 
                   RECAPITALIZATION, MERGER AND CONSOLIDATION
 
    (a) The existence of this Plan and Stock Options granted hereunder shall not
affect in any way the right or power of the Company or its stockholders to make
or authorize any or all adjustments, recapitalizations, reorganizations or other
changes in the Company's capital structure or its business, or any merger or
consolidation of the Company, or any issue of bonds, debentures, preferred or
prior preference stocks ranking prior to or otherwise affecting the Common Stock
or the rights thereof (or any rights, options or warrants to purchase same), or
the dissolution or liquidation of the Company, or any sale or transfer of all or
any part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise.
 
    (b) Subject to any required action by the stockholders, if the Company shall
be the surviving or resulting corporation in any merger or consolidation, any
outstanding Stock Option granted hereunder shall pertain to and apply to the
securities or rights (including cash, property or assets) to which a holder of
the number of shares of Common Stock subject to the Stock Option would have been
entitled. Notwithstanding any other provision of the Plan, and without affecting
the number of shares reserved or available hereunder, the Committee shall
authorize the issuance, continuation or assumption of outstanding Stock Options
or provide for other equitable adjustments after changes in the shares of Common
Stock resulting from any merger, consolidation, sale of assets, acquisition of
property or stock, recapitalization, reorganization, or similar occurrence in
which the Company is the continuing or surviving corporation, upon such terms
and conditions as it may deem necessary in order to preserve Participants'
rights under the Plan.
 
    (c) In the event of any reorganization, merger or consolidation pursuant to
which the Company is not the surviving or resulting corporation, or of any
proposed sale of substantially all of the assets of the Company, there may be
substituted for each share of Common Stock subject to the unexercised portions
of such outstanding Stock Option that number of shares of each class of stock or
other securities or that amount of cash, property or assets of the surviving or
consolidated company which were distributed or distributable to the stockholders
of the Company in respect of each share of Common Stock held by them, such
outstanding Stock Options to be thereafter exercisable for such stock,
securities, cash or property in accordance with their terms.
 
    (d) In the event of a Change in Control of the Company, then,
notwithstanding any other provision in the Plan to the contrary, all unmatured
installments of Stock Options outstanding shall thereupon automatically be
accelerated and exercisable in full.
 
    (e) Upon the occurrence of each event requiring an adjustment of the
exercise price and/or the number of shares purchasable pursuant to Stock Options
granted pursuant to the terms of this Plan, the Company shall mail forthwith to
each Participant a copy of its computation of such adjustment which shall be
conclusive and shall be binding upon each such Participant, except as to any
Participant who contests such computation by written notice to the Company
within thirty (30) days after receipt thereof by such Participant.

                   OPTIONS IN SUBSTITUTION FOR STOCK OPTIONS
                         GRANTED BY OTHER CORPORATIONS
 
    Stock Options may be granted under the Plan from time to time in
substitution for such stock options held by directors of a corporation who
become or are about to become directors of the Company as the result of a merger
or consolidation of the corporation with the Company or a Subsidiary or the
acquisition by either of the foregoing of stock of the corporation as the result
of which it becomes a Subsidiary.
 
                                  ARTICLE XIII
 
                            MISCELLANEOUS PROVISIONS
 
    13.1  EXERCISE OF STOCK OPTIONS.  Stock Options granted under the Plan may
be exercised during the option period, at such times and in such amounts, in
accordance with the terms and conditions and subject to such restrictions as are
set forth herein and in the applicable stock option agreements. Notwithstanding
anything to the contrary contained herein, Stock Options may not be exercised,
nor may shares be issued pursuant to a Stock Option if any necessary listing of
the shares on a stock exchange or any registration or qualification under state
or federal securities laws required under the circumstances has not been
accomplished.
 
    13.2  NON-ASSIGNABILITY.  A Stock Option granted to a Participant may not be
transferred or assigned, other than (i) by will or the laws of descent and
distribution or (ii) pursuant to a qualified domestic relations order (as
defined in Section 401(a)(13) of the Code or Section 206(d)(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")). Subject to the
foregoing, during a Participant's lifetime, Stock Options granted to a
Participant may be exercised only by the Participant or, if the particular stock
option agreement so provides, by the Participant's guardian or legal
representative.
 
    13.3  INVESTMENT INTENT.  The Company may require that there be presented to
and filed with it by any Participant(s) under the Plan, such evidence as it may
deem necessary to establish that the Stock Options granted or the shares of
Common Stock to be purchased or transferred are being acquired for investment
and not with a view to their distribution.
 
    13.4  STOCKHOLDERS' RIGHTS.  The holder of a Stock Option shall have none of
the rights or privileges of a stockholder except with respect to shares which
have been actually issued.
 
    13.5  INDEMNIFICATION OF BOARD AND COMMITTEE.  No current or previous member
of the Board or the Committee, nor any officer or employee of the Company acting
on behalf of the Board or the Committee, shall be personally liable for any
action, determination, or interpretation taken or made in good faith with
respect to the Plan, and all such members of the Board or the Committee and each
and any officer or employee of the Company acting on their behalf shall, to the
extent permitted by law, be fully indemnified and protected by the Company in
respect of any such action, determination or interpretation. The foregoing right
of indemnification shall not be exclusive of any other rights of indemnification
to which such individuals may be entitled under the Company's Certificate of
Incorporation or Bylaws, as a matter of law, or otherwise.
 
    13.6  INTERPRETATION.  Where the context permits, words in the masculine
gender shall include the feminine and neuter genders, the plural form of a word
shall include the singular form, and the singular form of a word shall include
the plural form. All references in this Plan to sections of the Code or ERISA
shall be deemed to include any successor provisions to such sections as
contained in any laws or regulations adopted or promulgated subsequent to August
1, 1996.

                               INPUT/OUTPUT, INC.
 
                  AMENDED AND RESTATED 1990 STOCK OPTION PLAN
 
1.  PURPOSE.
 
    The 1990 Stock Option Plan (the "Plan") is intended to provide a means of
attracting and retaining in the service of Input/Output, Inc. (the "Company")
and its Subsidiaries certain key employees of ability and potential, to
encourage such persons to exert their best efforts on behalf of the Company and
to align their interests more closely with those of the stockholders. It is
intended that these purposes will be effected through the granting of options,
which may be in the form of stock options intended to qualify ("Incentive Stock
Options") under Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code") or stock options which are not intended to so qualify ("Non-
Qualified Stock Options")
 
2.  ADMINISTRATION.
 
    The Plan shall be administered by the Compensation Committee (the
"Committee") of the Board of Directors of the Company (the "Board"), which
Committee shall consist of at least two members.
 
    The Committee shall have full power and authority to select the key
employees to be granted options hereunder at such time or times, in such
amounts, and upon such terms and conditions as the Committee may prescribe. The
Committee shall have full power and authority to interpret and construe the Plan
and to establish and amend general rules and regulations for the administration
of the Plan. The Committee's interpretation and construction of the Plan shall
be conclusive and binding upon all persons. Administrative costs in connection
with the Plan shall be paid by the Company.
 
    No current or previous member of the Board or the Committee, nor any officer
or employee of the Company acting on behalf of the Board or the Committee, shall
be personally liable for any action, determination, or interpretation taken or
made in good faith with respect to the Plan, and all such members of the Board
or the Committee and each and any officer or employee of the Company acting on
their behalf shall, to the extent permitted by law, be fully indemnified and
protected by the Company in respect of any such action, determination or
interpretation. The foregoing right of indemnification shall not be exclusive of
any other rights of indemnification to which such individuals may be entitled
under the Company's Certificate of Incorporation or Bylaws, as a matter of law,
or otherwise.
 
    Each option shall be evidenced by a written stock option agreement. Unless
otherwise provided in the resolution approving such grant, the date on which the
Committee approves the granting of an option shall be considered the date on
which such option is granted. The Committee shall prescribe the terms of each
option agreement, which terms shall not be inconsistent with the terms of this
Plan.
 
3.  ELIGIBILITY.
 
    The individuals who shall be eligible to participate in the Plan shall be
such key employees (including officers and directors who are employees) of the
Company or of any corporation or entity (hereinafter called a "Subsidiary") in
which the Company has a proprietary interest by reason of stock ownership or
otherwise (including any corporation or entity in which the Company acquires a
proprietary interest after the adoption of this Plan), but only if the Company
owns, directly or indirectly, stock or equity interests possessing not less than
50% of the total combined voting power of all classes of stock or equity
interests in such corporation. Such key employees shall be executive,
administrative, professional or technical personnel of the Company or of any
Subsidiary who have principal or shared responsibility for the management,
direction and financial success of the Company. More than one (1) option may be
granted from time to time to any employee. The holders of options shall not be,
or have any of the rights or privileges of, a stockholder of the Company in
respect of any shares purchasable upon the exercise of any part of an option
unless and until certificates representing such shares shall have been issued by
the Company to such holders.
<PAGE>
4.  STOCKHOLDER APPROVAL AND TERM.
 
    This Plan shall become effective as of the date approved by the stockholders
of the Company. Subject to its termination pursuant to Section 12, the Plan
shall remain in effect until all options granted hereunder shall have been
exercised, earned, or distributed, or shall have expired or have been canceled;
PROVIDED HOWEVER, that no options hereunder shall be granted after September 1,
2000.
 
5.  SHARES SUBJECT TO THE PLAN.
 
    Subject to adjustment pursuant to Section 9, the total number of shares of
common stock of the Company, $.01 par value ("Common Stock"), with respect to
which stock options may be granted hereunder shall not exceed 7,000,000. In the
event that shares of Common Stock are delivered to the Company in full or
partial payment of the exercise price for the exercise of a stock option granted
under the Plan in accordance with Section 6 of this Plan, the number of shares
available for future grants of options under the Plan shall be reduced only by
the net number of shares issued upon the exercise of the option.
 
    The aggregate number of shares of Common Stock that may be represented by
grants of stock options made to any optionee during any consecutive four-year
period may not exceed in any event 750,000 shares. Should any option granted
under this Plan expire or terminate unexercised, in whole or in part, the shares
of Common Stock formerly subject to such option shall again be available for
grant under the Plan. Shares granted or issued hereunder may be authorized but
unissued Common Stock or shares reacquired by the Company and held in its
treasury, as may from time to time be determined by the Committee.
 
6.  STOCK OPTIONS.
 
    All stock options granted hereunder shall be evidenced by written stock
option agreements setting forth the following terms and conditions:
 
        (a)  NUMBER OF SHARES.  The option agreement shall state the total
    number of shares to which it pertains.
 
        (b)  EXERCISE PRICE.  The exercise price shall be not less than the fair
    market value, as defined in Section 11(a) hereof, for each share of Common
    Stock on the date of grant of the option. If an Incentive Stock Option is
    granted to an employee and if the employee owns or is deemed to own (by
    reason of the attribution rules applicable under Section 424(d) of the Code)
    more than 10% of the combined voting power of all classes of stock of the
    Company (or of any parent corporation or Subsidiary of the Company), the
    exercise price for each share (to the extent required by the Code at the
    time of grant) shall not be less than 110% of the fair market value of a
    share of Common Stock on the date such Incentive Stock Option is granted.
 
        (c)  EXERCISE OF STOCK OPTION.  The Committee, in its sole discretion,
    shall prescribe in each option agreement the time or times at which a stock
    option shall be exercisable, in full or in part; PROVIDED that the
    Committee, in its sole discretion, may accelerate the time or times at which
    stock options shall became exercisable. In no event may an option be
    exercised or shares be issued pursuant to an option if any necessary listing
    of the shares on a securities exchange or any registration or qualification
    required under applicable state or federal securities laws has not been
    accomplished. Unless the Committee directs otherwise, an option granted
    hereunder may be exercised no sooner than as follows:

       1.  One (1) year from the date of grant           Up to 25% of the total optioned shares under the option
       2.  Two (2) years from the date of grant          Up to an additional 25% of the total optioned shares
       3.  Three (3) years from the date of grant        Up to an additional 25% of the total optioned shares
       4.  Four (4) years from the date of grant         Up to an additional 25% of the total optioned shares
</TABLE>
 
                                       2
<PAGE>
        (d)  EXERCISE PROCEDURES.  A stock option shall be exercised by delivery
    of written notice of exercise to the Secretary of the Company and payment of
    the full exercise price of the shares for which the option is being
    exercised. The exercise price may be paid:
 
           (1) in cash or by check payable to the order of the Company, or
 
           (2) through the delivery of Common Stock owned by the optionee,
       having an aggregate fair market value on the date of exercise equal to
       the exercise price, or
 
           (3) by any combination of (1) and (2) above.
 
    The Committee may impose such limitations and prohibitions on the use of
    shares of Common Stock to exercise an option as it deems appropriate.
    Additionally, shares covered by a stock option may be purchased upon
    exercise, in whole or in part, in accordance with the applicable stock
    option agreement, by authorizing a third party to sell the shares (or a
    sufficient portion thereof) acquired upon exercise of a stock option, and
    assigning the delivery to the Company of a sufficient amount of the sale
    proceeds to pay for all the shares acquired through such exercise and any
    tax withholding obligations resulting from such exercise.
 
        (e)  PERIOD OF OPTIONS.  The Committee shall prescribe in each stock
    option agreement the period during which a stock option may be exercised;
    PROVIDED HOWEVER, that no stock option shall be granted for a period of
    longer than ten years. However, if an employee owns or is deemed to own (by
    reason of the attribution rules of Section 424(d) of the Code) more than 10%
    of the combined voting power of all classes of stock of the Company (or any
    parent corporation or Subsidiary of the Company) and an Incentive Stock
    Option is granted to such employee, the term of such Incentive Stock Option
    (to the extent required by the Code at the time of grant) shall be no more
    than five years from the date of grant.
 
        (f)  INCENTIVE STOCK OPTIONS.  To the extent required by the Code for
    incentive stock options, the exercise of Incentive Stock Options granted
    under the Plan shall be subject to the $100,000 calendar year limit as set
    forth in Section 422(d) of the Code; to the extent that any grant exceeds
    such $100,000 calendar year limit, the portion of such granted Stock Option
    shall be deemed a Non-Qualified Stock Option.
 
        If Common Stock acquired upon exercise of an Incentive Stock Option is
    disposed of by an optionee prior to the expiration of either two years from
    the date of grant of such option or one year from the transfer of shares to
    the optionee pursuant to the exercise of such option or in any other
    disqualifying disposition within the meaning of Section 422 of the Code,
    then such optionee shall promptly notify the Company in writing of the date
    and terms of such disposition. A disqualifying disposition by an optionee
    shall not affect the status of any other option granted under the Plan as an
    Incentive Stock Option within the meaning of Section 422 of the Code.
 
        Notwithstanding the provisions of Section 7, the option period of an
    optionee's Incentive Stock Options shall terminate no later than ninety (90)
    days after termination of such optionee's employment with the Company and
    its Subsidiaries; PROVIDED that if such employment terminates by reason of
    the death or total and permanent disability (as defined in Section 22(e) of
    the Code) of the optionee, then the option period of such optionee's
    Incentive Stock Options shall terminate no later than one hundred eighty
    (180) days after such termination by reason of death or disability.
 
7.  TERM OF EMPLOYMENT.
 
    In the event an optionee shall cease to be employed by the Company, the
unexercised portions of such optionee's options which are eligible to be
exercised in accordance with this Plan as of the date of such termination of
employment may be exercised within one hundred eighty (180) days after such date
of termination; PROVIDED HOWEVER, that the option shall be exercisable as
follows in the event of death, disability or retirement:
 
                                       3
<PAGE>
        (a)  DEATH.  In the event of death while employed, all unmatured
    installments of the stock option outstanding shall thereupon automatically
    be accelerated and become fully vested and exercisable in full, and the
    stock option may be exercised, for a period of twelve (12) months after the
    optionee's death or until expiration of the option term (if sooner), by the
    optionee's estate or personal representative, or by the person who acquired
    the right to exercise the option by bequest or inheritance or by reason of
    the optionee's death; and
 
        (b)  RETIREMENT OR DISABILITY.  In the event of termination of
    employment as the result of retirement or disability, all unmatured
    installments of the stock option outstanding shall thereupon automatically
    be accelerated and become fully vested and exercisable in full, and the
    stock option may be exercised in full for a period of twelve (12) months
    after such termination or until expiration of the option term (if sooner).
    For the purposes of this Plan, the "retirement" of an optionee shall be
    deemed to be retirement after qualification therefor pursuant to a
    retirement plan or a retirement policy of the Company. Also, for the
    purposes of this Plan, the "disability" of an optionee shall mean the total
    and permanent disability (as that term is described in Section 22(e) of the
    Code) of such optionee.
 
8.  CHANGE OF CONTROL.
 
    In the event of a Change of Control affecting the Company, all unmatured
installments of outstanding options shall automatically be accelerated and
become fully vested and exercisable in full, without regard to the provisions of
subsection 6(c) hereof. For the purposes of this Plan, a "Change in Control"
shall mean the occurrence of any of the following events: (i) there shall be
consummated any merger or consolidation pursuant to which shares of the
Company's Common Stock would be converted into cash, securities or other
property, or any sale, lease, exchange or other disposition (excluding
disposition by way of mortgage, pledge or hypothecation), in one transaction or
a series of related transactions, of all or substantially all of the assets of
the Company (a "Business Combination"), in each case unless, following such
Business Combination, the holders of the outstanding Common Stock immediately
prior to such Business Combination beneficially own, directly or indirectly,
more than 51% of the outstanding common stock or equivalent equity interests of
the corporation or entity resulting from such Business Combination (including,
without limitation, a corporation which as a result of such transaction owns the

used in Rule 13d-5 promulgated under the 1934 Act), other than the Company, any
successor of the Company or any Subsidiary or any employee benefit plan of the
Company or any Subsidiary (including such plan's trustee), becomes a beneficial
owner for purposes of Rule 13d-3 promulgated under the 1934 Act, directly or
indirectly, of securities of the Company representing 40% or more of the
Company's then outstanding securities having the right to vote in the election
of directors, or (iv) during any period of two consecutive years, individuals
who, at the beginning of such period constituted the entire Board, cease for any
reason (other than death) to constitute a majority of the directors, unless the
election, or the nomination for election by the Company's stockholders, of each
new director was approved by a vote of at least a majority of the directors then
still in office who were directors at the beginning of the period.
 
9.  ADJUSTMENTS.
 
    (a) If at any time while the Plan is in effect or unexercised options are
outstanding, there shall be any increase or decrease in the number of issued and
outstanding shares of Common Stock through the declaration of a stock dividend
or through any recapitalization resulting in a stock split-up, combination, or
exchange of shares of Common Stock, then and in such event:
 
                                       4
<PAGE>
        (1) An appropriate adjustment shall be made in the maximum number of
    shares of Common Stock then subject to being awarded under the Plan to the
    end that the same proportion of the Company's issued and outstanding shares
    of Common Stock shall continue to be subject to being so awarded; and
 
        (2) Appropriate adjustments shall be made in the number of shares of
    Common Stock and the exercise price per share thereof then subject to
    purchase pursuant to each option previously granted, to the end that the
    same proportion of the Company's issued and outstanding shares of Common
    Stock in each such instance shall remain subject to purchase at the same
    aggregate exercise price.
 
    (b) Except as otherwise expressly provided herein, the issuance by the
Company of shares of its capital stock of any class, or securities convertible
into shares of capital stock of any class, either in connection with direct sale
or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of obligations of the Company convertible into such shares or other
securities, shall not affect, and no adjustment by reason thereof shall be made
with respect to, the number of or exercise price of shares of Common Stock then
subject to outstanding options granted under the Plan.
 
    Without limiting the generality of the foregoing, the presence of
outstanding options granted under the Plan shall not affect in any manner the
right or power of the Company to make, authorize or consummate (1) any or all
adjustments, recapitalizations, reorganizations or other changes in the
Company's capital structure or its business; (2) any merger or consolidation of
the Company; (3) any issuance by the Company of debt securities or preferred or
preference stock which would rank senior to the shares of Common Stock subject
to outstanding options; (4) the dissolution or liquidation of the Company; (5)
any sale, transfer or assignment of all or any part of the assets or business of
the Company; or (6) any other corporate act or proceeding, whether of a similar
character or otherwise.
 
    (c) Subject to any required action by the stockholders, if the Company shall
be the surviving or resulting corporation in any reorganization, merger or
consolidation, any outstanding stock option granted hereunder shall pertain to
and apply to the securities or rights (including cash, property or assets) to
which a holder of the number of shares of Common Stock subject to the stock
option would have been entitled. Notwithstanding any other provision of the
Plan, and without affecting the number of shares reserved or available
hereunder, the Committee shall authorize the issuance, continuation or
assumption of outstanding stock options or provide for other equitable
adjustments after changes in the shares of Common Stock resulting from any
merger, consolidation, sale of assets, acquisition of property or stock,
recapitalization, reorganization, or similar occurrence in which the Company is
the continuing or surviving corporation, upon such terms and conditions as it
may deem necessary in order to preserve optionees' rights under the Plan.
 
    (d) In the event of any reorganization, merger or consolidation pursuant to
which the Company is not the surviving or resulting corporation, or of any
proposed sale of all or substantially all of the assets of the Company, there
shall be substituted for each share of Common Stock subject to the unexercised
portions of such outstanding stock option that number of shares of each class of
stock or other securities or that amount of cash, property or assets of the
surviving or consolidated company which were distributed or distributable to the
stockholders of the Company in respect of each share of Common Stock held by
them, such outstanding stock options to be thereafter exercisable for such
stock, securities, cash or property in accordance with their terms.
 
    (e) Upon the occurrence of each event requiring an adjustment of the
exercise price and/or the number of shares purchasable pursuant to stock options
granted pursuant to the terms of this Plan, the Company shall mail forthwith to
each optionee a copy of its computation of such adjustment which shall be
conclusive and shall be binding upon each such optionee, except as to any
optionee who contests such computation by written notice to the Company within
thirty (30) days after receipt thereof by such optionee.
 
                                       5
<PAGE>
10.  OPTIONS IN SUBSTITUTION FOR STOCK OPTIONS GRANTED BY OTHER CORPORATIONS.
 
    Stock options may be granted under the Plan from time to time in
substitution for such options held by employees of a corporation or other entity
who become or are about to become key employees of the Company or a Subsidiary
as the result of a merger or consolidation of the employing corporation or
entity with the Company or a Subsidiary or the acquisition by the Company or a
Subsidiary of equity securities of the employing corporation or entity as the
result of which it becomes a Subsidiary. The terms and conditions of the
substitute options so granted may vary from the terms and conditions set forth
in Section 6 of this Plan to such extent as the Board or the Committee, as the
case may be, at the time of grant deem appropriate to conform, in whole or in
part, to the provisions of the options in substitution for which they are
granted.
 
11.  MISCELLANEOUS PROVISIONS.
 
    The following provisions shall apply hereunder:
 
        (a)  FAIR MARKET VALUE.  For the purposes of this Plan, "fair market
    value" of the Company's shares of Common Stock means (i) the closing sales
    price per share on the principal securities exchange on which the Common
    Stock is traded (or if there is no sale on the relevant date, then on the
    last previous day on which a sale was reported), or (ii) the mean between
    the closing or average (as the case may be) bid and asked prices per share
    of Common Stock on the over-the-counter market, whichever is applicable.
 
        (b)  NO RIGHT TO CONTINUE EMPLOYMENT.  Nothing in the Plan or in any
    stock option agreement confers upon any employee the right to continue in
    the employ of the Company or interferes with or restricts in any way the
    right of the Company to discharge any employee at any time.
 
        (c)  STOCKHOLDERS' RIGHTS.  The holder of a stock option shall have none
    of the rights or privileges of a stockholder except with respect to shares
    which have been issued.
 
        (d)  TAX REQUIREMENTS.  The employee receiving shares issued upon
    exercise of any stock option shall be required to pay the Company the amount
    of any taxes which the Company is required to withhold with respect to such
    shares of Common Stock. Such payment shall be required to be made prior to
    or concurrent with the delivery of any certificate representing such shares
    of Common Stock. Such payment may be made in cash, by check, or through the
    delivery of shares of Common Stock which the employee owns or is entitled to
    receive after payment of the exercise price, which shares have an aggregate
    fair market value equal to the required withholding payment, or any
    combination thereof. With respect to an Incentive Stock Option, in the event
    of a subsequent disqualifying disposition of Common Stock within the meaning
    of Section 422 of the Code, such payment of taxes may be made in cash, by
    check or through the delivery of shares of Common Stock which the employee
    then owns, which shares have an aggregate fair market value equal to the
    required withholding payment, or any combination thereof.
 
        (e)  GOVERNMENT REGULATIONS.  Notwithstanding any of the provisions
    hereof, or of any written agreements evidencing options granted hereunder,
    the obligation of the Company to sell and deliver shares shall be subject to
    all applicable laws, rules and regulations and to such approvals by any
    government agencies or national securities exchanges as may be required. The
    employee shall agree not to exercise any stock option, and the Company shall
    not be obligated to issue any shares, if the exercise thereof or if the
    issuance of shares shall constitute a violation by the employee or the
    Company of any provision of any law or regulation of any governmental
    authority.
 
        (f)  BENEFIT PLAN COMPUTATIONS.  Any benefits received or amounts paid
    to an employee with respect to any option under the Plan shall not affect
    the level of benefits provided to or received by any employee, or the
    employee's estate or beneficiary, pursuant to any employee benefit plan of
    the Company.
 
        (g)  NONTRANSFERABILITY OF OPTION.  A stock option granted to an
    optionee may not be transferred or assigned, other than (i) by will or the
    laws of descent and distribution or (ii) pursuant to
 
                                       6
<PAGE>
    a qualified domestic relations order (as defined in Section 401(a)(13) of
    the Code or Section 206(d)(3) of the Employee Retirement Income Security Act
    of 1974, as amended ("ERISA")), PROVIDED, that in the case of an Incentive
    Stock Option, such transfer or assignment may occur only to the extent it
    will not result in disqualifying such option as an incentive stock option
    under Section 422 of the Code, or any successor provision. Subject to the
    foregoing, during an optionee's lifetime, stock options granted to an
    optionee may be exercised only by the optionee or, provided the particular
    stock option agreement so provides, by the optionee's guardian or legal
    representative.
 
        (h)  EMPLOYMENT.  Employment by the Company shall be deemed to include
    employment by a Subsidiary. The Committee shall have the authority to
    determine whether or not an optionee has terminated his employment with the
    Company.
 
        (i)  INVESTMENT INTENT.  The Company may require that there be presented
    to and filed with it by any optionee(s) under the Plan, such evidence as it
    may deem necessary to establish that the options or the shares of Common
    Stock to be purchased or transferred are being acquired for investment and
    not with a view to their distribution.
 
        (j)  INTERPRETATION.  Where the context requires, words in the masculine
    gender shall include the feminine and neuter genders, the plural form of a
    word shall include the singular form, and the singular form of a word shall
    include the plural form. All references in this Plan to sections of the Code
    or sections of ERISA shall be deemed to include any successor provisions to
    such sections as contained in any laws or regulations adopted subsequent to
    August 1, 1996.
 
12.  SUSPENSION, TERMINATION OR AMENDMENT OF THE PLAN.
 
    Subject to the limitations set forth in this Section 12, the Board may at
any time and from time to time, without the consent of the optionees, alter,
amend, revise, suspend, or discontinue the Plan in whole or in part, except that
the Board shall not amend this Plan in any manner which would have the effect of
preventing Incentive Stock Options granted under this Plan from being "incentive
stock options" as defined in Section 422 of the Code, although it is recognized
that stock options are not prevented from being "incentive stock options" at
grant solely because the requirements of Section 422 of the Code are not met
upon exercise of the stock option or sale of the Common Stock acquired upon
exercise, or as a result of any cancellation of the stock option.
 
    In addition, the Board shall have the power to amend the Plan in any manner
advisable in order for stock options granted under the Plan to qualify for the
exemption provided by Rule 16b-3 (or any successor rule relating to exemption
from Section 16(b) of the 1934 Act) or to qualify as "performance-based"
compensation under Section 162(m) of the Code (including amendments as a result
of changes to Rule 16b-3 or Section 162(m) or the regulations promulgated
thereunder to permit greater flexibility with respect to stock options granted
under the Plan), and any such amendment shall, to the extent deemed necessary or
advisable by the Committee, be applicable to any outstanding stock options
theretofore granted under the Plan, notwithstanding any contrary provisions
contained in any stock option agreement. In the event of any such amendment to
the Plan, the holder of any stock option outstanding under the Plan shall, upon
request of the Committee and as a condition to the exercisability thereof,
execute a conforming amendment in the form prescribed by the Committee to any
stock option agreement relating thereto within such reasonable time as the
Committee shall specify in such request. Notwithstanding anything contained in
this Plan to the contrary, unless required by law, no action contemplated or
permitted by this Section 12 shall adversely affect any rights of optionees or
obligations of the Company to optionees with respect to any stock options
theretofore granted under the Plan without the consent of the affected optionee.
