                         ANNUAL MEETING OF SHAREHOLDERS
                            TO BE HELD JULY 19, 2000
                 -----------------------------------------------


                             SOLICITATION OF PROXIES


         This Proxy Statement is furnished in connection with the solicitation
by the Board of Directors of the Company of proxies from the holders of record
of the common stock, par value $.01 per share (the "Common Stock"), at the close
of business on May 25, 2000, for use at the Annual Meeting to be held at 10:00
a.m., CST, on July 19, 2000, and any adjournment thereof. This Proxy Statement,
the attached proxy and the Company's Annual Report for the fiscal year ended
January 31, 2000 are being mailed together on or about May 26, 2000, to
shareholders entitled to notice of and to vote at the Annual Meeting. The
principal executive office of the Company is Post Office Box 1175, 44000 Highway
75 South, Huntsville, Texas 77342.

         Properly executed proxies will be voted as directed. If no direction is
indicated therein, proxies received in response to this solicitation will be
voted FOR: (i) the election of the seven nominees for director; (ii) the
approval of the Company's 2000 Stock Option Plan; (iii) the ratification of the
indicated independent public accountants; and (iv) as recommended by the Board
of Directors with regard to any other matters or if no recommendation is given,
in their own discretion.

         A proxy on the enclosed form may be revoked by the shareholder at any
time before it is voted by filing with the Secretary of the Company a written
revocation, by voting in person at the meeting, or by delivering a proxy bearing
a later date. Attendance at the Annual Meeting will not, in itself, constitute
revocation of the proxy.

         The Company will bear all costs of this Proxy Statement and the proxy
and the cost of soliciting proxies relating to the Annual Meeting. It is
anticipated that the solicitation of proxies for the Annual Meeting will be made
only by use of the mails and will cost approximately $13,000. However, the
Company may use the services of its directors, officers and employees to solicit
proxies personally or by telephone, without additional salary or compensation to
them. The Company will request that the brokerage houses, custodians, nominees,
and fiduciaries forward the proxy soliciting materials to the beneficial owners
of the Company's shares held of record for such persons, and the Company will
reimburse such persons for their related reasonable out-of-pocket expenses.

                              VOTING OF SECURITIES

         At the close of business on May 25, 2000, the record date for the
determination of shareholders entitled to notice of and to vote at the Annual
Meeting, there were 9,276,712 issued and outstanding shares of Common Stock,
each of which share is entitled to one vote. Common Stock is the only class of
outstanding securities of the Company entitled to notice of and to vote at the
Annual Meeting.

         The Company's Bylaws provide that the presence, either in person or by
proxy, of the holders of a majority of the outstanding shares of Common Stock
entitled to vote at the Annual Meeting is necessary to constitute a quorum for
the transaction of business. Assuming such a majority is present, the election
of directors will require a plurality of the votes cast at the Annual Meeting.
The adoption of the 2000 Stock Option Plan and ratification of the selected
independent public accountants will require the affirmative vote of a majority
of the shares entitled to vote and that voted or abstained at the Annual
Meeting. Abstentions from and broker non-votes on the proposal to elect
directors will be counted for purposes of determining the presence of a quorum,
but will not be included in the total shares voted for or against any nominee. A
broker non-vote occurs if a broker or other nominee holding shares for a
beneficial owner does not vote on a proposal because he does not have
discretionary authority to vote shares and has not received instructions from
the beneficial owner with respect to such proposal. Thus, abstentions from the
proposals will have the same legal effect as a vote against the proposals, but a
broker non-vote will not be counted for purposes of determining whether a
majority is achieved.

         (1) The options terminate on the earlier of their expiration date or 10
         years after grant or, generally, immediately on termination for reasons
         other than retirement, disability, death or without cause; three months
         after termination of employment or retirement; 12 months after
         termination for disability, death or without cause; or unless the
         Compensation Committee determines otherwise, on the consummation of a
         specified change of control transaction. The options become exercisable
         in three equal annual installments beginning one year after the grant
         date, but vesting is accelerated on the consummation of a specified
         change of control.

         (2) The indicated 5% and 10% rates of appreciation are provided to
         comply with Securities and Exchange Commission regulations and do not
         necessarily reflect the views of the Company as to the likely trend in
         the stock price. Actual gains, if any, on stock option exercises and
         the sale of Common Stock holdings will depend on, among other things,
         the future performance of the Common Stock and overall stock market
         conditions.

         EMPLOYMENT AGREEMENT. Billy F. Mitcham, Jr.'s employment agreement with
the Company is for a term of five years, beginning January 15, 1997, which term
is automatically extended for successive one-year periods unless either party
gives written notice of termination at least 30 days prior to the end of the
current term. The Employment Agreement replaced his previous employment
agreement. The Employment Agreement provides for an annual salary of $150,000
(increased to $187,500 effective February 1, 1998) and a bonus at the discretion
of the Board of Directors. It may be terminated prior to the end of the initial
term or any extension thereof if Mr. Mitcham dies; if it is determined that Mr.
Mitcham has become disabled (as defined); if Mr. Mitcham gives three months
prior notice of resignation; if the Company gives Mr. Mitcham notice of
termination "without cause"; or if the Board of Directors determines that Mr.
Mitcham has breached the Employment Agreement in any material respect, has
appropriated a material business opportunity of the Company or has engaged in
fraud or dishonesty with respect to the Company's business or is convicted of or
indicted for any felony criminal offense or any crime punishable by
imprisonment. If Mr. Mitcham terminates his employment within 60 days following
(i) a material reduction in his duties and responsibilities (without his
consent) or (ii) a reduction in, or failure by the Company to pay when due, any
portion of his salary, he will be entitled to payments equal to $450,000,
payable ratably over the 24 months following such termination. For a period of
two years after the termination of the Employment Agreement, Mr. Mitcham is
prohibited from engaging in any business activities which are competitive with
the Company's business and from diverting any of the Company's customers to a
competitor. The Company has no employment agreements with any of its other
executive officers.

         CHANGE OF CONTROL AND TERMINATION AGREEMENTS. In February 1999, the
Company entered into severance and change of control agreements with Messrs.
Paul Mitcham, Sheppard and Dupuis. Under the terms of the severance and change
of control agreements, if a covered executive officer's employment terminates
during the 24-month period after a "change of control" of the Company (as
defined in the agreements) (such period, the "Protection Period") other than the
officer's voluntary resignation (except as stated below) or retirement or a
termination of employment for "cause" (as defined in the agreements) or by
reason of death or disability, the

officer will be entitled to receive certain severance payments and other
benefits. The officer's voluntary resignation for "good reason" (as defined in
the agreements) will also entitle the officer to the severance benefits and
other benefits. The severance payment amount, payable monthly over the 24 months
after termination, will be equal to two times such officer's annual base salary
on the effective date of the change of control or the date of the termination of
employment. In addition, the officer under those circumstances will be entitled
to receive continued medical and dental coverage under the Company's applicable
plans (to the extent permitted by law or by the plan carriers) for the period of
time remaining in the Protection Period after his termination is effective, or
until the officer becomes eligible to obtain comparable coverage from a
subsequent employer. In addition, any stock options and restricted stock that
have not fully vested shall accelerate and immediately become fully vested. Each
agreement terminates on January 1, 2002, but will automatically renew for
additional one-year terms absent prior written notice from the Company that it
is terminating the agreements.

         COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION. The Company's
executive compensation program is designed to attract, motivate and retain
talented management personnel and to reward management for the Company's
successful financial performance and for increasing shareholder value. The
Company's executive compensation has three components: base salaries, annual
performance bonuses and long-term incentive stock-based awards.

         BASE SALARIES. We determine the salary ranges for the Company's
executive officers based upon their responsibilities and the salary levels of
similarly positioned officers in comparable companies. Our philosophy has been
to establish base salaries in the median-to-low end of the range of such
salaries at comparable companies, because long-term stock based compensation is
considered more important than annual base salaries in aligning the executive's
financial rewards to the shareholders' financial interests for the long term. In
fiscal 2000, as part of the Company's continuing efforts to optimize its capital
resources, none of the Company's executive officers received an increase in
their base salaries.

         ANNUAL PERFORMANCE BONUS. Annual bonuses are awarded on a discretionary
basis. In making our determination of whether to award an annual bonus and the
amount of the bonus, we consider several factors, including financial
performance of the Company in relation to planned expectations and performance
of the Company in relation to industry conditions, each executive officer's
performance, level of responsibility or duties, successful completion of
particular projects or acquisition and implementation of new technical
knowledge. We have not yet determined bonuses for executive officers for fiscal
2000, and expect to do so at our meeting immediately following the Annual
Meeting.

         LONG-TERM STOCK-BASED COMPENSATION. We believe that a substantial
percentage of executive compensation should be directly related to improvement
in shareholder value. In determining the number of options to grant, we make a
subjective determination based on the same factors as we do in determining
bonuses, giving special consideration to the Chief Executive Officer's
recommendation in awarding options to executive officers other than himself. In
fiscal 2000, we approved the grant to executive officers of the options shown in
the Summary Compensation Table for that fiscal year, with a three-year vesting
period. However, we soon realized that the Company did not have sufficient
options remaining available for option grants in the future. Since we believe
that the grant of stock options is an important component of our ability to keep
our management team in place, we recommended to the Board that it either adopt
another stock option plan or authorize additional shares under an existing plan,
and present it to shareholders for approval.

                     CERTAIN TRANSACTIONS AND RELATIONSHIPS

         Effective September 20, 1993, the Company and Billy F. Mitcham, Jr.
entered into a Voting Agreement (the "Voting Agreement") with Billy F. Mitcham,
Sr., Paul C. Mitcham and two trusts established for the benefit of Mr. Mitcham,
Jr.'s sons. Under the Voting Agreement, the holders of shares subject thereto
have agreed that Mr. Mitcham, Jr. has the authority to vote an additional
245,638 shares, or 2.6%, of the Company's outstanding Common Stock. Mr. Mitcham,
Jr. had voting control of an aggregate of 671,888 shares, or 7.1%, of the
Company's Common Stock, as of May 25, 2000. The Voting Agreement will terminate
on the earlier of the agreement of the parties, the transfer by the parties
thereto of their shares or the expiration of 25 years. See "Principal Holders of
Securities and Security Ownership of Management."

                 PROPOSAL TO APPROVE THE 2000 STOCK OPTION PLAN

         On May 22, 2000, the Board of Directors adopted the Company's 2000
Stock Option Plan (the "2000 Stock Option Plan") subject to approval by the
Company's shareholders at the Annual Meeting. The 2000 Stock Option Plan
supplements the Company's 1998 Incentive Stock Plan (the "1998 Plan"), which the
Company's shareholders approved on July 9, 1998, and the 1994 Stock Option Plan,
which the Company's shareholders approved on May 1, 1994. As of May 25, 2000,
348,500 of the 350,000 options authorized for issuance under the 1998 Plan have
been granted, all of which options remained unexercised, and 319,820 of the
350,000 options authorized for issuance under the 1994 Plan have been granted,
191,700 of which remained unexercised. The 1998 Plan and the 1994 Plan provide
for the grant of stock options only to the Company's employees. The 2000 Stock
Option Plan covers an aggregate of up to 500,000 shares of Common Stock (subject
to certain adjustments) and provides for grant of stock options to employees,
consultants and non-employee directors. The principal advantage to the Company
of the 2000 Stock Option Plan is to enable the Company to better attract,
retain, and develop a top-quality management team.

         The following discussion is a summary of certain key provisions of the
2000 Stock Option Plan and is subject to qualification by reference to the 2000
Stock Option Plan, a copy of which is attached to this Proxy Statement as
EXHIBIT A.

Administration

         The 2000 Stock Option Plan will be administered by the Compensation
Committee of the Board of Directors. The Compensation Committee will have the
power to determine which employees will receive an award, the time or times when
such award will be made, the type of the award and the number of shares of
Common Stock to be issued under the award or the value of the award. Only
persons who at the time of the award are employees, consultants or non-employee
directors of the Company or of any subsidiary of the Company will be eligible to
receive awards under the 2000 Stock Option Plan.

Types of Awards

         The 2000 Stock Option Plan provides for the grant of incentive and
non-qualified stock options. Prior to the grant of any award, the Committee may
establish performance goals that are based on the attainment of specified
corporate objectives. The Compensation Committee will designate the key
employees, consultants or non-employee directors to receive the options, the
number of shares subject to the options, and the terms and conditions of each
option granted under the 2000 Stock Option Plan. The term of any option granted
under the 2000 Stock Option Plan shall be determined by the Compensation
Committee, except that the term of any incentive stock option cannot exceed 10
years from the date of the grant and any incentive stock option granted to an
optionee who possesses more than 10% of the total combined voting power of all
classes of shares of the Company or of its subsidiaries will not be exercisable
after the expiration of five years from the date of grant. No option may be
exercised sooner than six months from the date of grant. The exercise price per
share of Common Stock for options granted under the 2000 Stock Option Plan will
be determined by the Compensation Committee, except that the exercise price of
an incentive stock option cannot be less than the fair market value of a share
of Common Stock on the date the option is granted. Further, the exercise price
of any incentive stock option granted to an employee who possesses more than 10%
of the total combined voting power of all classes of shares of the Company or of
its subsidiaries must be at least 110% of the fair market value of the share at
the time such option is granted. The exercise price of options granted under the
2000 Stock Option Plan will be paid in full in a manner prescribed by the
Compensation Committee. The 2000 Stock Option Plan permits holders of options,
with approval of the Compensation Committee, to relinquish all or any part of
the unexercised portion thereof in exchange for replacement under certain
circumstances.

Change of Control Provisions

         If there is a "Change of Control" (as defined in the 2000 Stock Option
Plan), all outstanding options shall immediately vest and become exercisable or
satisfiable, as applicable. The Committee in its discretion may determine that
on a Change of Control, each Award (other than an Option) shall terminate within
a specified number of days after notice to the holder, and each holder shall
receive cash in the amount equal to the excess of the "Change of Control Value",
as defined in the 2000 Stock Option Plan. With respect to options, the Committee
may effect any one of the following alternatives: (i) determine a limited period
of time on or before a specified date (before or after the Change of Control)
after which specified date all unexercised options shall terminate, (ii) require
the mandatory surrender to the Company by the holders of some or all of the
outstanding options held by the holders as of the date of the Change of Control
specified by the Committee, in which case the Committee shall cancel the options
and the Company shall pay the excess of the Change of Control Value of the share
subject to such option over the exercise prices under such options for such
shares, (iii) make such adjustments to options then outstanding as the Committee
deems appropriate to reflect such Change of Control, or (iv) provide that
thereafter upon any exercise of an option the holder shall be entitled to
purchase under such option, in lieu of the number of shares of stock then
covered by such option the number and class of shares stock or other securities
or property to which the holder would have been entitled under the agreement of
merger, consolidation, or sale of assets






                                       12
<PAGE>   15

and dissolution if, immediately prior to such merger, consolidation or sale of
assets and dissolution, the holder has been the holder of record of the number
of shares of stock then covered by such option.

Federal Income Tax Consequences

         INCENTIVE STOCK OPTIONS. An employee will generally not recognize
income on receipt or exercise of an incentive stock option ("ISO") so long as he
or she has been an employee of the Company or its subsidiaries from the date the
option was granted until three months before the date of exercise; however, the
amount by which the fair market value of the stock at the time of exercise
exceeds the option price is a required adjustment for purposes of the
alternative minimum tax applicable to the employee. If the employee holds the
stock received on exercise of the option for one year after exercise (and for
two years from the date of grant of the option), any difference between the
amount realized upon the disposition of the stock and the amount paid for the
stock will be treated as long-term capital gain (or loss, if applicable) to the
employee. If the employee exercises an ISO and satisfies these holding period
requirements, the Company may not deduct any amount in connection with the ISO.

         In contrast, if an employee exercises an ISO but does not satisfy the
holding period requirements with respect to the stock acquired on exercise, the
employee generally will recognize ordinary income in the year of the disposition
equal to the excess, if any, of the fair market value of the stock on the date
of exercise over the option price; and any excess of the amount realized on the
disposition over the fair market value on the date of exercise will be taxed as
long- or short-term capital gain (as applicable). If, however, the fair market
value of the stock on the date of disposition is less than on the date of
exercise, the employee will recognize ordinary income equal only to the
difference between the amount realized on disposition and the exercise price. In
either event, the Company will be entitled to deduct an amount equal to the
amount constituting ordinary income to the employee in the year of the premature
disposition.

         NONQUALIFIED STOCK OPTIONS. Nonqualified stock options granted under
the 2000 Stock Option Plan are not taxable to an employee when granted but
result in taxation at exercise, at which time the optionee will recognize
ordinary income in an amount equal to the difference between the option exercise
price and the fair market value of the shares on the exercise date. The Company
will be entitled to deduct a corresponding amount as a business expense in the
year the optionee recognizes this income.

Plan Amendment and Termination

         The Board may alter or amend the 2000 Stock Option Plan from time to
time but no change in any Award may be made which would impair the rights of the
holder without the consent of the holder and the Board may not, without approval
of the shareholders, amend the 2000 Stock Option Plan to (a) increase the
maximum number of shares which may be issued on exercise or surrender of Award
(except in certain cases of Changes in Control as more fully set forth in the
2000 Stock Option Plan), (b) change the Option price, (c) change the class of
employees eligible to receive Awards, (d) extend the maximum period during which
awards may be granted under the 2000 Stock Option Plan, (e) materially modify
the requirements as to eligibility for participation in the 2000 Stock Option
Plan, or (f) or decrease any authority granted to the Committee in contravention
of Rule 16b-3 under the Securities Exchange Act of 1934 (the "Exchange Act"). No
grants may be made under the 2000 Stock Option Plan after May 22, 2010. The 2000
Stock Option Plan shall remain in effect until all Awards granted have been
satisfied or expired.

Transfer and Resale Restrictions

         The options are not transferrable except in the event of the
participant's death or under a "qualified domestic relations order" as defined
under applicable law. The employees of the Company may not offer or resell
shares acquired under the 2000 Stock Option Plan without registration under the
Securities Act of 1933, or compliance with Rule 144. On May 25, 2000, the
closing price of the Common Stock as reported in The Wall Street Journal for
Nasdaq National Market transactions was $5 9/16.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE 2000
STOCK OPTION PLAN.

         RATIFICATION OF SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS

         The Board of Directors has selected Hein + Associates LLP, which has
served as independent public accountants of the Company since 1993, as
independent public accountants to audit the books, records and accounts of the
Company for the fiscal year ended January 31, 2001. The Board of Directors
recommends a vote FOR approval of such selection. A representative of Hein +
Associates LLP is expected to be present at the Annual Meeting and will have the
opportunity to make a statement, if such representative chooses to do so, and
will be available to respond to appropriate questions.

                                  ANNUAL REPORT

         The Company's Annual Report covering the fiscal year ended January 31,
2000 accompanies this Proxy Statement. Except for the financial statements
included in the Annual Report that are specifically incorporated by reference
herein, the Annual Report is not incorporated in this Proxy Statement and is not
to be deemed part of this proxy soliciting material. Additional copies of the
Annual Report are available upon request.

                                    FORM 10-K

         The company will furnish without charge to each person whose proxy is
being solicited, upon the request of any such person, a copy of the company's
annual report on form 10-K for the fiscal year ended January 31, 2000, as filed
with the SEC (excluding exhibits), including the financial statements and
schedules thereto. Requests for copies of such report should be directed in
writing to the secretary, Mitcham Industries, Inc., Post Office Box 1175, 44000
Highway 75 South, Huntsville, Texas 77342.

                                  OTHER MATTERS

         COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT. Section 16(a) of the
Exchange Act requires the Company's directors, executive officers and persons
who own more than 10% of a registered class of the Company's Common Stock to
file initial reports of ownership and changes in ownership with the SEC and to
furnish the Company with copies of all Section 16(a) forms they file. Based upon
a review of such forms and any amendments thereto furnished to the Company
during the fiscal year ended January 31, 2000, Billy F. Mitcham, Jr. and William
J. Sheppard did not timely report exercises of warrants in May 1999 to purchase
3,074 and 427 shares of common stock, respectively. The Company believes that
all other filings required to be made under Section 16(a) were timely made.

         OTHER MATTERS. At the date hereof, the Board of Directors does not know
of any other business to be presented at the Annual Meeting of Shareholders. If
any other matter properly comes before the meeting, however, it is intended that
the persons named in the accompanying proxy will vote such proxy in accordance
with the discretion and instructions of the Board of Directors.

                       SUBMISSION OF SHAREHOLDER PROPOSALS

         Shareholders wishing to submit proposals for consideration by the
Company's Board of Directors at the Company's 2001 Annual Meeting of
Shareholders should submit them in writing to the attention of the Secretary of
the Company no later than January 30, 2001, so that it may be considered by the
Company for inclusion in its proxy statement and form of proxy for that meeting.

         A shareholder who wishes to make a proposal at the 2001 Annual Meeting
of Shareholders without complying with the requirements of Rule 14a-8 (and
therefore without including the proposal in the Company's proxy materials) must
notify the Company of that proposal by April 15, 2001. If a shareholder fails to
timely give notice, then the persons named as proxies in the proxy cards
solicited by the Company's Board of Directors for that meeting will be entitled
to vote the proxy cards held by them regarding that proposal, if properly raised
at the meeting, in their discretion or as directed by the Company's management.

                                    By Order of the Board of Directors,

without having been exercised in full, the unpurchased Shares which were subject

         4. ADMINISTRATION OF THE PLAN.

                  (a) PROCEDURE.

                           (i) ADMINISTRATION WITH RESPECT TO DIRECTORS AND
                  OFFICERS OR TO NON-EMPLOYEE DIRECTORS. With respect to grants
                  of Options to Employees who are also officers or directors of
                  the Company, or to Non-Employee Directors, the Plan shall be
                  administered by (A) the Board or (B) a Committee designated by
                  the Board to administer the Plan, which Committee shall be
                  constituted in such a manner as to permit the Plan to comply
                  with Rule 16b-3 promulgated under the Exchange Act or any
                  successor thereto ("Rule 16b-3") with respect to a plan
                  intended to qualify thereunder as a discretionary plan. Once
                  appointed, such Committee shall continue to serve in its
                  designated capacity until otherwise directed by the Board.
                  From time to time the Board may increase the size of the
                  Committee and appoint additional members, remove members (with
                  or without cause) and appoint new members in substitution
                  therefor, fill vacancies, however caused, and remove all
                  members of the Committee and thereafter directly administer
                  the Plan, all to the extent permitted by Rule 16b-3 with
                  respect to a plan intended to qualify thereunder as a
                  discretionary plan. Notwithstanding the foregoing, the Plan
                  shall not be administered by the Board if (a) the Company and
                  its officers and directors are then subject to the
                  requirements of Section 16 of the Exchange Act and (b) the
                  Board's administration of the Plan would prevent the Plan from
                  complying with Rule 16b-3.

                           (ii) ADMINISTRATION WITH RESPECT TO CONSULTANTS AND
                  OTHER EMPLOYEES. With respect to grants of Options to
                  Employees or Consultants who are neither directors nor
                  officers of the Company, the Plan shall be administered by (A)
                  the Board or (B) a Committee designated by the Board, which
                  Committee shall be constituted in such a manner as to satisfy
                  the legal requirements relating to the administration of
                  incentive stock option plans, if any, of corporate and
                  securities laws applicable to the Company and of the Code (the
                  "Applicable Laws"). Once appointed, such Committee shall
                  continue to serve in its designated capacity until otherwise
                  directed by the Board. From time to time the Board may
                  increase the size of the Committee and appoint additional
                  members thereof, remove members (with or without cause) and
                  appoint new members in substitution therefor, fill vacancies,
                  however caused, and remove all members of the Committee and
                  thereafter directly administer the Plan, all to the extent
                  permitted by the Applicable Laws.

                  (b) POWERS OF THE ADMINISTRATOR. Subject to the provisions of
         the Plan and in the case of a Committee, the specific duties delegated
         by the Board to such Committee, the Administrator shall have the
         authority, in its discretion:

                           (i) to determine the Fair Market Value of the Stock,
                  in accordance with Section 2(j) of the Plan;

                           (ii) to select the officers, Consultants and
                  Employees to whom Options may from time to time be granted
                  hereunder;

                           (iii) to determine whether and to what extent Options
                  are granted hereunder;

                           (iv) to determine the number of shares of Stock to be
                  covered by each such award granted hereunder;



                                      A-3
<PAGE>   21
                           (v) to approve forms of agreement for use under the
                  Plan;

                           (vi) to determine the terms and conditions, not
                  inconsistent with the terms of the Plan, of any award granted
                  hereunder (including, but not limited to, the per share
                  exercise price for the Shares to be issued pursuant to the
                  exercise of an Option and any restriction or limitation, or
                  any vesting acceleration or waiver of forfeiture restrictions
                  regarding any Option or other award and/or the shares of Stock
                  relating thereto, based in each case on such factors as the
                  Administrator shall determine, in its sole discretion);

                           (vii) to determine whether and under what
                  circumstances an Option may be bought-out for cash under
                  subsection 9(f);

                           (viii) to determine whether, to what extent and under
                  what circumstances Stock and other amounts payable with
                  respect to an award under this Plan shall be deferred either
                  automatically or at the election of the participant (including
                  providing for and determining the amount, if any, of any
                  deemed earnings on any deferred amount during any deferral
                  period); and

                           (ix) to reduce the exercise price of any Option to
                  the then current Fair Market Value if the Fair Market Value of
                  the Stock covered by such Option shall have declined since the
                  date the Option was granted.

                  (c) EFFECT OF COMMITTEE'S DECISION. All decisions,
         determinations and interpretations of the Administrator shall be final
         and binding on all Optionees and any other holders of any Options.
         Neither the Board, the Committee nor any member thereof shall be liable
         for any act, omission, interpretation, construction or determination
         made in connection with the Plan in good faith, and the members of the
         Board and of the Committee shall be entitled to indemnification and
         reimbursement by the Company in respect of any claim, loss, damage or
         expense (including counsel fees) arising therefrom to the full extent
         permitted by law.

                  5. ELIGIBILITY.

                  (a) Nonqualified Stock Options may be granted to Employees,
         Consultants and Non-Employee Director. Incentive Stock Options may be
         granted only to Employees.

                  (b) Each Option shall be designated in the written option
         agreement as either an Incentive Stock Option or a Nonqualified Stock
         Option. However, notwithstanding such designations, to the extent that
         the aggregate Fair Market Value of the Shares with respect to which
         Options designated as Incentive Stock Options are exercisable for the
         first time by any Optionee during any calendar year (under all plans of
         the Company or any Parent or Subsidiary) exceeds $100,000, such excess
         Options shall be treated as Nonqualified Stock Options.

                  (c) For purposes of Section 5(b), Incentive Stock Options
         shall be taken into account in the order in which they were granted,
         and the Fair Market Value of the Shares shall be determined as of the
         time the Option with respect to such Shares is granted.

                  (d) The Plan shall not confer upon any Optionee any right with
         respect to continuation of employment or consulting relationship with
         the Company, nor shall it interfere in any way with his right or the
         Company's right to terminate his employment or consulting relationship
         at any time, with or without cause, unless otherwise agreed in writing
         by the Company and such Optionee.

         6. TERM OF PLAN. The Plan shall become effective upon its adoption by
the Board of Directors. It shall continue in effect until May 22, 2010 unless
extended by the Board or sooner terminated under Section 14 of the Plan. No
grants of Options will be made under the Plan after May 22, 2010.

         7. TERM OF OPTION. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that in the case of an Incentive Stock
Option, the term shall be no more than 10 years from the date of grant thereof
or such shorter term as may be provided in the Option Agreement. However, in the
case of an Incentive Stock Option granted to an Optionee who, at the time the
Option is granted, owns Stock representing more than 10% of the voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five years from the date of grant thereof or such shorter term
as may be provided in the Option Agreement.

         8. OPTION EXERCISE PRICE AND CONSIDERATION.

                  (a) The per share exercise price for the Shares to be issued
         pursuant to exercise of an Option shall be such price as is determined
         by the Administrator, provided that, in the case of an Incentive Stock
         Option:

                           (i) granted to an Employee who, at the time of the
                  grant of such Incentive Stock Option, owns stock representing
                  more than ten percent (10%) of the voting power of all classes
                  of stock of the Company or any Parent or Subsidiary, the per
                  Share exercise price shall be no less than 110% of the Fair
                  Market Value per Share on the date of grant.

                           (ii) granted to any Employee, the per Share exercise
                  price shall be no less than 100% of the Fair Market Value per
                  Share on the date of grant.

                  (b) The consideration to be paid for the Shares to be issued
         upon exercise of an Option, including the method of payment, shall be
         determined by the Administrator (and, in the case of an Incentive Stock
         Option, shall be determined at the time of grant) and may consist
         entirely of (1) cash, (2) check, (3) promissory note, (4) other shares
         of the Company's capital stock which (x) in the case of shares of the
         Company's capital stock acquired upon exercise of an Option either have
         been owned by the Optionee for more than six months on the date of
         surrender or were not acquired, directly or indirectly, from the
         Company, and (y) have a Fair Market Value on the date of surrender
         equal to the aggregate exercise price of the Shares as to which said
         Option shall be exercised, (5) authorization for the Company to retain
         from the total number of Shares as to which the Option is exercised
         that number of Shares having a Fair Market Value on the date of
         exercise equal to the exercise price for the total number of Shares as
         to which the Option is exercised, (6) delivery of a properly executed
         exercise notice together with irrevocable instructions to a broker to
         promptly deliver to the Company the amount of sale or loan proceeds
         required to pay the exercise price, (7) any combination of the
         foregoing methods of payment, or (8) such other consideration and
         method of payment for the issuance of Shares to the extent permitted
         under applicable laws.

         9. EXERCISE OF OPTION.

                  (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any
         Option granted hereunder shall be exercisable at such times and under
         such conditions as determined by the Administrator, including
         performance criteria with respect to the Company and/or the Optionee,
         and as shall be permissible under the terms of the Plan. An Option may
         not be exercised for a fraction of a Share.

                  An Option shall be deemed to be exercised, and the Optionee
         deemed to be a shareholder of the Shares being purchased upon exercise,
         when written notice of such exercise has been given to the



                                      A-5
<PAGE>   23

         Company in accordance with the terms of the Option by the person
         entitled to exercise the Option and full payment for the Shares with
         respect to which the Option is exercised has been received by the
         Company. Full payment may, as authorized by the Board, consist of any
         consideration and method of payment allowable under Section 8(b) of the
         Plan.

                  Exercise of an Option in any manner shall result in a decrease
         in the number of Shares which thereafter may be available, both for
         purposes of the Plan and for sale under the Option, by the number of
         Shares as to which the Option is exercised.

                  (b) TERMINATION OF EMPLOYMENT. In the event of termination of
         an Optionee's relationship as a Consultant (unless such termination is
         for purposes of becoming an Employee of the Company) or Continuous
         Status as an Employee with the Company (as the case may be), such
         Optionee may, but only within ninety (90) days (or such other period of
         time as is determined by the Board, with such determination in the case
         of an Incentive Stock Option being made at the time of grant of the
         Option after the date of such termination (but in no event later than
         the expiration date of the term of such Option as set forth in the
         Option Agreement)), exercise his Option to the extent that an Optionee
         was entitled to exercise it at the date of such termination. To the
         extent that an Optionee was not entitled to exercise the Option at the
         date of such termination, or if Optionee does not exercise such Option
         to the extent so entitled within the time specified herein, the Option
         shall terminate.

                  (c) DISABILITY OF OPTIONEE. Notwithstanding the provisions of
         Section 9(b) above, in the event of termination of an Optionee's
         relationship as a Consultant or Continuous Status as an Employee as a
         result of his total and permanent disability (as defined in Section
         22(e)(3) of the Code), Optionee may, but only within twelve (12) months
         from the date of such termination (but in no event later than the
         expiration date of the term of such Option as set forth in the Option
         Agreement), exercise the Option to the extent otherwise entitled to
         exercise it at the date of such termination. To the extent that
         Optionee was not entitled to exercise the Option at the date of
         termination, or if Optionee does not exercise such Option to the extent
         so entitled within the time specified herein, the Option shall
         terminate.

                  (d) DEATH OF OPTIONEE. In the event of the death of an
         Optionee, the Option may be exercised, at any time within twelve (12)
         months following the date of death (but in no event later than the
         expiration date of the term of such Option as set forth in the Option
         Agreement), by the Optionee's estate or by a person who acquired the
         right to exercise the Option by bequest or inheritance, but only to the
         extent the Optionee was entitled to exercise the Option at the date of
         death. To the extent that Optionee was not entitled to exercise the
         Option at the date of termination, or if the Optionee's estate (or such
         other person who acquired the right to exercise the Option) does not
         exercise such Option to the extent so entitled within the time
         specified herein, the Option shall terminate.

                  (e) RULE 16b-3. Options granted to persons subject to Section
         16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain
         such additional conditions or restrictions as may be required
         thereunder to qualify for the maximum exemption from Section 16 of the
         Exchange Act with respect to Plan transactions.

                  (f) BUYOUT PROVISIONS. The Administrator may at any time offer
         to buy out for a payment in cash or Shares, an Option previously
         granted, based on such terms and conditions as the Administrator shall
         establish and communicate to the Optionee at the time that such offer
         is made.

         10. NON-TRANSFERABILITY OF OPTIONS. The Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.



                                      A-6
<PAGE>   24
         11. STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS. At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph. When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by electing to have the Company withhold
from the Shares to be issued upon exercise of the Option, that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined (the "Tax Date").

         All elections by an Optionee to have Shares withheld for this purpose
shall be made in writing in a form acceptable to the Administrator and shall be
subject to the following restrictions:

                  (a) the election must be made on or prior to the applicable
         Tax Date;

                  (b) once made, the election shall be irrevocable as to the
         particular Shares of the Option as to which the election is made;

                  (c) all elections shall be subject to the consent or
         disapproval of the Administrator; and

                  (d) if the Optionee is subject to Rule 16b-3, the election
         must comply with the applicable provisions of Rule 16b-3 and shall be
         subject to such additional conditions or restrictions as may be
         required thereunder to qualify for the maximum exemption from Section
         16 of the Exchange Act with respect to Plan transactions.

         In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

         12. CHANGES IN THE COMPANY'S CAPITAL STRUCTURE. The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its shareholders 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 stock ahead of or
affecting the Stock or the rights thereof, 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.

         If the Company shall effect a subdivision or consolidation of shares or
other capital readjustment, the payment of a stock dividend, or other increase
or reduction of the number of shares of the Stock outstanding, without receiving
compensation therefor in money, services or property, then (a) the number,
class, and per share price of shares of Stock subject to outstanding Options
hereunder shall be appropriately adjusted in such a manner as to entitle an
Optionee to receive upon exercise of an Option, for the same aggregate cash
consideration, the same total number and class of shares as he would have
received had he exercised his Option in full immediately prior to the event
requiring the adjustment; and (b) the number and class of shares of Stock then
reserved for issuance under the Plan shall be adjusted by substituting for the
total number and class of shares of Stock then reserved that number and class of
shares of stock that would have been received by the owner of an equal number of
outstanding shares of each class of Stock as the result of the event requiring
the adjustment.

         If the Company is a party to a merger or a similar reorganization after
which the Company is not the surviving corporation, or if there is a sale of all
or substantially all the Common Stock or a sale of all or substantially all of
the assets of the Company, or if the Company is to be liquidated or dissolved
(any of which events shall constitute a "Significant Transaction"), then,
subject to the provisions hereof, the Administrator, in




                                      A-7

its discretion, may accelerate the vesting of all outstanding Options or take
such other action with respect to outstanding Options as it deems appropriate,
including, without limitation, canceling such outstanding Options and paying the
Optionees an amount equal to the value of such Options, as determined by the
Board.

         Notwithstanding the foregoing, if a Significant Transaction shall occur
in connection with or following a Change in Control (as defined below), in
connection with which Significant Transaction the holder of any Option that is
not fully vested shall not receive, in respect of such Option, a substitute
award of stock options containing substantially similar terms to and having an
equal or greater fair market value than such Option, then the Administrator
shall either:

                  (a) accelerate the vesting of such Option within a reasonable
         time prior to the completion of such Significant Transaction (such that
         the holder of such Option would have the opportunity to participate in
         the Significant Transaction on the same basis as holders of Stock,
         subject to such holder's exercise of such Option) or

                  (b) cancel such Option in consideration of the payment to the
         holder thereof of an amount (in cash) equal to the fair market value of
         such Option. For purposes of the foregoing, the fair market value
         attributable to Options shall be determined by the Administrator
         either, at its election, (x) in accordance with the Black-Scholes
         method (for purposes of which volatility shall be measured over the
         preceding one year period and the risk-free interest rate shall be the
         rate of U.S. treasury bills with a maturity corresponding to the
         remaining term of such Option) or (y) to be an amount equal to the fair
         market value of the Stock subject to such Option less the exercise
         price thereof and (ii) the fair market value of (A) any Options shall
         be determined as of the date, either of the Change in Control or of the
         Significant Transaction, that results in the greater fair market value
         of such Options, and (B) any substitute award shall be determined as of
         the date of the Significant Transaction.

A "Change in Control" shall be deemed to occur if:

                  (a) any Person becomes (directly or indirectly) the beneficial
         owner (within the meaning of Rule 13d-3 promulgated under such Act) of
         more than 25% of the combined voting power of the then-outstanding
         voting securities of the Company entitled to vote generally in the
         election of directors ("Outstanding Company Voting Securities"); or

                  (b) the Company's shareholders approve a merger or
         consolidation, sale or disposition of all or substantially all of the
         Company's assets or a plan of liquidation or dissolution of the
         Company, unless, immediately thereafter:

                           (i) more than 60% of the combined voting power of the
                  then-outstanding voting securities of the resulting
                  corporation entitled to vote generally in the election of
                  directors is then beneficially owned, directly or indirectly,
                  by all or substantially all of the individuals and entities
                  who were the beneficial owners of the Outstanding Company
                  Voting Securities immediately before the Reorganization, in
                  substantially the same proportions of the Outstanding Company
                  Voting Securities as their ownership immediately before such
                  Reorganization;

                           (ii) no Person beneficially owns, directly or
                  indirectly, 25% or more of the then- outstanding voting
                  securities of such corporation entitled to vote generally in
                  the election of directors; and

                           (iii) at least a majority of the members of the board
                  of directors of the corporation resulting from the
                  Reorganization were members of the Incumbent Board at the time
                  the initial agreement providing for the Reorganization was
                  entered into.



                                      A-8
<PAGE>   26

                  Notwithstanding the foregoing, a Change in Control shall not
                  occur if any corporation or entity the majority interest of
                  which is held, directly or indirectly, by the Company,
                  acquires 25% or more of the Outstanding Company Voting
                  Securities.

Except as expressly provided herein, the issue by the Company of shares of stock
of any class, or securities convertible into shares of stock of any class, for
cash or property, or for labor or services either upon 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, class, or price of shares of Stock then subject to
outstanding Options.

         13. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Employee, Consultant or
Non-Employee Director to whom an Option is so granted within a reasonable time
after the date of such grant.

         14. AMENDMENT AND TERMINATION OF THE PLAN.

                  (a) AMENDMENT AND TERMINATION. The Board may at any time
         amend, alter, suspend or discontinue the Plan, but no amendment,
         alteration, suspension or discontinuation shall be made which would
         impair the rights of any Optionee under any grant theretofore made,
         without his or her consent. In addition, to the extent necessary and
         desirable to comply with Rule 16b-3 under the Exchange Act or with
         Section 422 of the Code (or any other applicable law or regulation,
         including the applicable requirements of The Nasdaq Stock Market or an
         established stock exchange), the Company shall obtain shareholder
         approval of any Plan amendment in such a manner and to such a degree as
         required.

                  (b) EFFECT OF AMENDMENT OR TERMINATION. Any such amendment or
         termination of the Plan shall not affect Options already granted and
         such Options shall remain in full force and effect as if this Plan had
         not been amended or terminated, unless mutually agreed otherwise
         between the Optionee and the Board, which agreement must be in writing
         and signed by the Optionee and the Company.

         15. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

         As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

         16. RESERVATION OF SHARES. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan. The inability of the Company
to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

         17. AGREEMENTS. Options shall be evidenced by written agreements
("Option Agreement") in such form as the applicable Administrator shall approve
from time to time.



                                      A-9
<PAGE>   27

         18. INFORMATION TO OPTIONEES. The Company shall provide to each
Optionee, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
generally provided to all shareholders of the Company. The Company shall not be
required to provide such information to persons whose duties in connection with
the Company assure their access to equivalent information.

         19. GOVERNING LAW; CONSTRUCTION. All rights and obligations under the
Plan shall be governed by, and the Plan shall be construed in accordance with,
the laws of the State of Texas without regard to the principles of conflicts of
laws. Titles and headings to Sections herein are for purposes of reference only,
and shall in no way limit, define or otherwise affect the meaning or
interpretation of any provisions of the Plan.
