                      DOSKOCIL MANUFACTURING COMPANY, INC.
                 1997 STOCK OPTION PLAN, AS AMENDED AND RESTATED


I.       THE PLAN.

         1.1 Purpose.

         The purpose of this Plan is to promote the success of the Company(1) by
providing an additional means to attract, motivate, retain and reward key
personnel through the grant of Options that provide added long-term incentives
for high levels of performance and for significant efforts to improve the
financial performance of the Company.

         1.2 Administration.

         (a) This Plan shall be administered by the Committee. Action of the
Committee with respect to the administration of this Plan shall be taken
pursuant to a majority vote or the unanimous written consent of its members. If
action by the Committee is taken by written consent, the action shall be deemed
to have been taken at the time specified in the consent or, if none is
specified, at the time of the last signature. The Committee may delegate
ministerial non-discretionary functions to third parties, including officers or
employees of the Company.

         (b) Subject to the express provisions of this Plan, the Committee shall
have the authority to construe and interpret this Plan and any agreements
defining the rights and obligations of the Company and Participants under this
Plan, to further define the terms used in this Plan, to prescribe, amend and
rescind rules and regulations relating to the administration of this Plan, to
determine the duration and purposes of leaves of absence which may be granted to
Participants without constituting a termination of their employment or
consulting services for purposes of this Plan and to make all other
determinations necessary or advisable for the administration of this Plan. The
determination of the Committee on any of the foregoing matters shall be
conclusive and binding on all parties.

         (c) Any action taken by, or inaction of, the Company, the Board or the
Committee relating to this Plan shall be within the absolute discretion of that
entity or body. In determining whether to take action under the Plan, the Board
or Committee may rely upon the advice of counsel, accountants, appraisers and
other experts. No member of the Board or Committee, or officer of the Company
shall be liable for any such action or inaction.

         (d) Subject to the requirements of Section 4.1(e), the Board, at any
time it so desires, may increase or decrease the number of members of the
Committee, may remove from membership on the Committee all or any portion of its
members, and may appoint such person or persons as it desires to fill any
vacancy existing on the Committee,


----------
(1) For a definition of this and other capitalized terms, see Section 4.1,
Definitions.

<PAGE>   4


whether caused by removal, resignation or otherwise. The Board may also, at any
time, assume or change the administration of this Plan.

         1.3 Participation.

         Options may be granted only to those persons that the Committee
determines to be Eligible Persons. An Eligible Person who has been granted an
Option may, if otherwise eligible, be granted additional Options if the
Committee shall so determine. Members of the Board who are not officers or
employees of the Company shall not be eligible to receive Incentive Stock
Options.

         1.4 Stock Subject to the Plan.

         The stock to be offered under this Plan shall be shares of the
Corporation's authorized but unissued Common Stock. The Common Stock may be
delivered for any lawful consideration, but not less than minimum lawful
consideration under Texas law. The aggregate amount of Common Stock that may be
issued or transferred pursuant to Options (including Incentive Stock Options)
granted under this Plan shall not exceed the sum of 1,500,000 Shares, subject to
adjustment as set forth in Section 3.2. The maximum number of Shares which may
be delivered pursuant to Options granted during any one year period to any
individual Participant under this Plan shall not exceed 200,000, subject to
adjustment as set forth in Section 3.2. If any Option shall lapse or terminate
without having been exercised in full, the unpurchased Shares subject thereto
shall again, except to the extent prohibited by law, be available and reserved
for Options under this Plan. The foregoing sentence does not apply to any Common
Stock withheld under Section 3.6.

         1.5 Grant of Options.

         Subject to the express provisions of this Plan, the Committee shall
determine from the class of Eligible Persons those individuals to whom Options
under this Plan shall be granted, the terms of Options (which need not be
identical) and the number of Shares subject to each Option. Each Option shall be
evidenced by an Option Agreement, the form of which must be approved by the
Committee, signed by the Corporation, and, if required by the Committee, by the
Participant. The grant of an Option is made on the Grant Date, unless the
Committee specifies a later date. Each Option shall be subject to the terms and
conditions set forth in this Plan and such other terms and conditions
established by the Committee as are not inconsistent with the purpose and
provisions of this Plan and set forth in the applicable Option Agreement.

         1.6 Exercise of Options.

         An Option shall be deemed to be exercised when the Secretary of the
Corporation receives written notice of such exercise from the Participant, which
notice shall specify the number of Shares with respect to which the Option is
being exercised, together with an executed Exercise Agreement in such form as
prescribed by the Committee and payment of the Purchase Price made in accordance
with Section 2.2(a), except to the extent payment may be permitted to be made
following delivery of written notice of exercise in accordance with Section
2.2(b), and any applicable withholding tax in


                                       2
<PAGE>   5


accordance with Section 3.6. The date on which the Corporation certifies the
satisfaction of these conditions by written acceptance of the notice, which
certification shall not be unreasonably delayed or withheld, shall be deemed to
be the exercise date. Notwithstanding any other provision of this Plan, the
Committee may impose, by rule and in Option Agreements, such conditions upon the
exercise of Options (including, without limitation, conditions limiting the time
of exercise to specified periods) as may be required to satisfy applicable
regulatory requirements and applicable law.

II.      OPTIONS.

         2.1 Grants.

         One or more Options may be granted to any Eligible Person. Each Option
so granted shall be designated by the Committee as either a Nonqualified Stock
Option or an Incentive Stock Option. Incentive Stock Options may be granted to
Eligible Persons who are employed by the Corporation or a corporation that is a
"parent" or "subsidiary" corporation within the meaning of Section 424(e) and
424(f) of the Code, respectively.

         2.2 Option Price.

         (a) The Purchase Price per share of Common Stock covered by each Option
shall be determined by the Committee at the time of the grant of the Option, but
in the case of Incentive Stock Options shall not be less than 100% (110% in the
case of a Participant who owns more than 10% of the total combined voting power
of all classes of stock of the Company) of the Fair Market Value of the Common
Stock on the date the Incentive Stock Option is granted. The Purchase Price of
any Shares purchased shall be paid in full at the time of each purchase in one
or a combination of the following methods: (i) in cash or by check payable to
the order of the Corporation, (ii) if authorized by the Committee or specified
in applicable Option Agreement, by a promissory note made by the Participant in
favor of the Corporation, in a form and upon such terms and conditions as the
Committee may require or approve, and secured by the Common Stock issuable upon
exercise in compliance with applicable law (including, without limitation, state
corporate law and federal margin requirements), or (iii) if authorized by the
Committee or specified in the applicable Option Agreement, by shares of Common
Stock of the Company already owned by the Participant; provided, however, that
any Shares delivered which were initially acquired upon exercise of a stock
option must have been owned by the Participant at least six months as of the
date of delivery. Shares used to satisfy the Purchase Price of an Option shall
be valued at their Fair Market Value on the date of exercise.

         (b) In addition to the payment methods described in subsection (a), an
Option Agreement or the Committee may provide that the Option can be exercised
and payment made by delivering a properly executed exercise notice together with
irrevocable instructions to a bank or broker to promptly deliver to the Company
the amount of sale or loan proceeds necessary to pay the Purchase Price and,
unless otherwise provided by the Committee, any applicable tax withholding under
Section 3.6. The Company shall not be


                                       3
<PAGE>   6


obligated to deliver certificates for any Shares unless and until it receives
full payment of the Purchase Price therefor.

         2.3 Option Period.

         Each Option and all rights or obligations thereunder shall expire on
such date as shall be determined by the Committee, but not later than 10 years
after the Grant Date, and shall be subject to earlier termination as set forth
in this Plan or the Option Agreement.

         2.4 Exercise of Options.

         Except as otherwise provided in Sections 3.2 and 3.3, an Option shall
become exercisable in whole or in part, on the date or dates specified in the
Option Agreement and thereafter shall remain exercisable until the expiration or
earlier termination of the Option. No Option shall be exercisable for at least
six months after the Grant Date, except in the case of death or Total
Disability. The Committee may, at any time after the grant of an Option and from
time to time, increase the number of Shares purchasable at any time so long as
the total number of Shares subject to the Option is not increased. No Option
shall be exercisable except in respect of whole Shares, and fractional Share
interests shall be disregarded. Not less than 100 Shares may be purchased at one
time unless the number purchased is the total number at the time available for
purchase under the terms of the Option.

         2.5 Limitations on Grant of Incentive Stock Options.

         (a) To the extent that the aggregate fair market value of stock with
respect to which incentive stock options first become exercisable by a
Participant in any calendar year exceeds $100,000, taking into account both
Common Stock subject to Incentive Stock Options under this Plan and stock
subject to incentive stock options under all other plans of the Company, such
options shall be treated as nonqualified stock options. For purposes of
determining whether the $100,000 limit is exceeded, the fair market value of
stock subject to options shall be determined as of the date the options are
awarded. In reducing the number of options treated as incentive stock options to
meet the $100,000 limit, the most recently granted options shall be reduced
first. To the extent a reduction of simultaneously granted options is necessary
to meet the $100,000 limit, the Company may, in the manner and to the extent
permitted by law, designate which Shares are to be treated as Shares acquired
pursuant to the exercise of an incentive stock option.

         (b) There shall be imposed in any Option Agreement relating to
Incentive Stock Options such terms and conditions as are required in order that
the Option be an "incentive stock option" as that term is defined in Section 422
of the Code.

         (c) No Incentive Stock Option may be granted to any person who, at the
time the Incentive Stock Option is granted, owns shares of outstanding Common
Stock possessing more than 10% of the total combined voting power of all classes
of stock of the Company, unless the Purchase Price of such Option is at least
110% of the Fair


                                       4
<PAGE>   7


Market Value of the stock subject to the Option and such Option by its terms is
not exercisable after the expiration of five years from the date such Option is
granted.

         (d) Any Participant who exercises an Incentive Stock Option shall give
prompt written notice to the Corporation of any sale or other transfer of the
Shares acquired under such Option if such sale or other transfer occurs within
one year after the exercise date or two years after the Grant Date.

         2.6 Option Repricing/Cancellation and Regrant/Waiver of Restrictions.

         Subject to Section 1.4 and Section 3.7 and the specific limitations on
Options contained in this Plan, the Committee from time to time may authorize,
generally or in specific cases only, for the benefit of any Eligible Person any
adjustment in the Purchase Price, the vesting schedule, the number of Shares
subject to, the restrictions upon, or the term of, an Option granted under this
Section 2 by cancellation of an outstanding Option and a subsequent regranting
of an Option, by amendment, by substitution of an outstanding Option, by waiver
or by other legally valid means. Subject to Section 1.4 and Section 3.7 and the
specific limitations on Options contained in this Plan, such amendment or other
action may, among other changes, result in a Purchase Price which is higher or
lower than the Purchase Price of the original or prior Option (but subject to
the pricing limit on the date of the change), provide for a greater or lesser
number of Shares subject to the Option, or provide for a longer or shorter
vesting or exercise period.

         2.7 Options in Substitution for Stock Options Granted by Other
Corporations.

         Options may be granted to Eligible Persons under this Plan in
substitution for employee stock options granted by other entities to persons who
are or who will become Eligible Persons in respect of the Company, in connection
with a distribution, merger or reorganization by or with the granting entity or
an affiliated entity, or the acquisition by the Company, directly or indirectly,
of all or a substantial part of the stock or assets of the other entity.

III.     OTHER PROVISIONS.

         3.1 Rights of Eligible Persons, Participants and Beneficiaries.

         (a) Status as an Eligible Person shall not be construed as a commitment
that any Option will be made under this Plan to such Eligible Person or to
Eligible Persons generally.

         (b) Nothing contained in this Plan (or in Option Agreements or in any
other documents related to this Plan or to Options) shall confer upon any
Eligible Person or Participant any right to continue in the service or employ of
the Company or constitute any contract or agreement of service or employment, or
interfere in any way with the right of the Company to reduce such person's
compensation or other benefits or to terminate the services or employment of
such Eligible Person or Participant, with or without cause, but nothing
contained in this Plan or any document related thereto shall affect any other
contractual right of any Eligible Person or Participant. The Committee


                                       5
<PAGE>   8


may, however, condition a grant upon a Participant's commitment to future or
continued service.

         (c) Amounts payable or shares deliverable pursuant to an Option shall
be paid or delivered only to the Participant or, in the event of the
Participant's death, to the Participant's Beneficiary or, in the event of the
Participant's Total Disability, to the Participant's Personal Representative or,
if there is none, to the Participant. Other than by will or the laws of descent
and distribution or other exception to transfer restrictions expressly
authorized by the Committee in the Option Agreement, no benefit payable or
Shares deliverable under, or interest in, this Plan or in any Option shall be
subject in any manner to anticipation, alienation, sale, transfer, assignment,
pledge, encumbrance or charge and any such attempted action shall be void. No
such benefit or interest shall be, in any manner, liable for, or subject to,
debts, contracts, liabilities, engagements or torts of any Eligible Person,
Participant or Beneficiary. The Committee shall disregard any attempted
transfer, assignment or other alienation prohibited by this paragraph and shall
pay or deliver such cash or shares of Common Stock in accordance with the
provisions of this Plan. Beneficiary designations authorized by the Committee
are not subject to these restrictions.

         (d) No Participant, Beneficiary or other person shall have any right,
title or interest in any fund or in any specific asset (including shares of
Common Stock) of the Corporation by reason of any Option granted hereunder.
Neither the provisions of this Plan (or of any documents related hereto), nor
the creation or adoption of this Plan, nor any action taken pursuant to the
provisions of this Plan shall create, or be construed to create, a trust of any
kind or a fiduciary relationship between the Corporation and any Participant,
Beneficiary or other person. To the extent that a Participant, Beneficiary or
other person acquires a right to receive an Option hereunder, such right shall
be no greater than the right of any unsecured general creditor of the Company.

         (e) The Articles of Incorporation and By-Laws of the Corporation, as
either of them may be amended from time to time, may provide for additional
restrictions and limitations with respect to the Common Stock (including further
restrictions and limitations on the transfer of Shares). To the extent that
these restrictions and limitations are greater than those provided for in this
Plan, Option Agreements and any other documents related to an Option, such
restrictions and limitations shall apply to Shares acquired pursuant to the
exercise of Options and are incorporated herein by this reference.

         3.2 Adjustments Upon Changes in Capitalization; Acceleration; Possible
Early Termination of Options.

         (a) If the outstanding shares of Common Stock are changed into or
exchanged for cash or a different number or kind of shares or securities of the
Corporation or of another issuer, or if additional Shares or new or different
securities are distributed with respect to the outstanding shares of Common
Stock, through a reorganization or merger to which the Corporation is a party,
or through a combination, consolidation, recapitalization, reclassification,
stock split, stock dividend, reverse stock split, stock


                                       6
<PAGE>   9


consolidation or other capital change or adjustment, the Committee shall provide
(but only to the extent it deems equitable and appropriate) for an adjustment in
the number and kind of Shares or other consideration that is subject to or may
be delivered under this Plan and pursuant to outstanding Options and in the
Purchase Price (and other terms, in the discretion of the Committee, necessarily
affected by such change) of outstanding Options.

         (b) Upon the occurrence of an Event, 50% of the then unvested portion
of each Option shall become immediately exercisable, unless (i) prior to the
Event the Committee determines that, upon its occurrence, there shall be no
acceleration of benefits under Options or designates certain exceptions to or
different time periods in respect of the Event for such acceleration, (ii) the
Option Agreement expressly provides that the Participant will not be entitled to
benefits of acceleration under this Section 3.2(b), or (iii) the Committee has
overridden any limits on acceleration in this Section 3.2(b) by providing in the
Option Agreement for unconditional acceleration. The Committee also may accord
any Participant a right to refuse any acceleration (with such consequences as
the Committee may impose) or may increase the percentage of the unvested portion
of an Option which vested pursuant to the preceding sentence, whether pursuant
to the Option Agreement or otherwise. The Committee may accelerate vesting and
exercisability in anticipation of an Event or on a case-by-case basis or on any
other basis in such circumstances as the Committee deems appropriate and in the
interest of the Corporation.

         (c) If an Option is exercisable or the exercisability of an Option (in
whole or in part) has been accelerated pursuant to 3.2(b), and the Option is not
exercised prior to the occurrence of the Event, the Committee may, at any time
prior to the occurrence of the Event, provide that the Option shall terminate.
Alternatively, if an Event occurs, the Committee may in its discretion provide
for the assumption, substitution, conversion, exchange or other settlement (in
cash or Common Stock in lieu of and in complete satisfaction of the Option)
and/or adjustment (each a "modification") of the Option pursuant to Section
3.2(a).

         3.3 Termination of Employment.

         (a) If a Participant's service to or employment by the Company
terminates for any reason other than Retirement, death or Total Disability, the
Participant shall have, subject to earlier termination pursuant to or as
contemplated by Section 2.3, three months or such shorter period as is provided
in such Participant's Option Agreement from the date of termination of services
or employment to exercise any Option to the extent it shall have become
exercisable on the date of termination of employment or services, and any Option
not exercisable on that date shall terminate. Notwithstanding the preceding
sentence, in the event a Participant is terminated for cause, as determined by
the Committee in its sole discretion, all Options of such Participant (whether
or not then vested) shall terminate immediately upon such termination of
services or employment.

         (b) If a Participant's service to or employment by the Company
terminates as a result of Retirement or Total Disability, the Participant or the
Participant's Personal Representative, as the case may be, shall have, subject
to earlier termination pursuant to


                                       7
<PAGE>   10


or as contemplated by Section 2.3, 12 months or such shorter period as is
provided in such Participant's Option Agreement from the date of termination of
services or employment to exercise the Option to the extent it shall have become
exercisable by the date of termination of services or employment and any Option
not exercisable on that date shall terminate.

         (c) If a Participant's service to or employment by the Company
terminates as a result of death while the Participant is rendering services to
or is employed by the Company or during the 12 month period referred to in
subsection (b) above, the Participant's Option shall be exercisable by the
Participant's Beneficiary, subject to earlier termination pursuant to or as
contemplated by Section 2.3, during the 12 month period or such shorter period
as is provided in such Participant's Option Agreement following the
Participant's death, as to all or any part of the shares of Common Stock covered
thereby to the extent exercisable on the date of death (or earlier termination).

         (d) In the event of a termination of services to or employment with the
Company for any reason, other than discharge for cause, the Committee may, in
its discretion, increase the vested portion of a Participant's Option, upon such
terms as the Committee shall determine.

         (e) If an entity ceases to be a Subsidiary, such action shall be deemed
for purposes of this Section 3.3 to be a termination of services or employment
of each consultant or employee of that entity who does not continue as a
consultant or as an employee of another entity within the Company.

         (f) If a Participant is not an employee but provides services under an
agreement or arrangement, the Committee shall be the sole judge of whether the
Participant continues to render services to the Company, unless the contract or
Option Agreement otherwise provides. By written notice to the Participant, the
Committee may determine whether a termination of services of such Participant
for purposes of this Plan has occurred. In such event (unless the agreement or
arrangement or Option Agreement otherwise expressly provides), the Participant's
termination of services for purposes of this Section 3.3 shall be the date which
is 10 days after the Committee's mailing of the notice.

         3.4 Securities Laws.

         (a) No Participant shall make any disposition of all or any portion of
shares of Common Stock acquired upon exercise of an Option, except in compliance
with applicable federal and state securities laws and unless and until:

                  (i) there is then in effect a registration statement under the
         Securities Act covering such proposed disposition and such disposition
         is made in accordance with such registration statement; or

                  (ii) such disposition is made in accordance with Rule 144
         under the Securities Act; or


                                       8
<PAGE>   11


                  (iii) such Participant notifies the Corporation of the
         proposed disposition and furnishes the Corporation with a statement of
         the circumstances surrounding the proposed disposition, and if
         requested by the Corporation, Participant furnishes the Corporation
         with an opinion of counsel acceptable to Corporation's counsel, that
         such disposition will not require registration under the Securities Act
         and will be in compliance with applicable state securities laws.

         Notwithstanding anything else contained herein or in any related
document to the contrary, the Corporation has no obligation to register the
Common Stock or file any registration statement under either federal or state
securities laws, nor does the Corporation make any representation concerning the
likelihood of a public offering of the Common Stock.

         (b) All certificates evidencing shares of Common Stock issued or
delivered under this Plan shall bear any appropriate or required legends under
applicable laws.

         3.5 Government Regulations.

         This Plan, the granting, vesting, and exercise of Options under this
Plan and the issuance or transfer of shares of Common Stock (and/or the payment
of money) pursuant thereto are subject to all applicable federal and state laws,
rules and regulations and to such approvals by any regulatory or governmental
agency (including, without limitation, "no action" positions of the Commission)
which may, in the opinion of counsel for the Corporation, be necessary or
advisable in connection therewith. Without limiting the generality of the
foregoing, no Options may be granted under this Plan, and no shares shall be
issued by the Corporation, nor cash payments made by the Corporation, pursuant
to or in connection with any such Option, unless and until, in each such case,
all legal requirements applicable to the issuance or payment have, in the
opinion of counsel to the Corporation, been complied with. In connection with
any stock issuance or transfer, the person acquiring the Shares shall, if
requested by the Corporation, give assurances satisfactory to counsel to the
Corporation in respect of such matters as the Corporation may deem desirable to
assure compliance with all applicable legal requirements (including but not
limited to federal and state securities law matters).

         3.6 Tax Withholding.

         (a) Upon the disposition by a Participant or other person of shares of
Common Stock acquired pursuant to the exercise of an Incentive Stock Option
prior to satisfaction of the holding period requirements of Section 422 of the
Code, or upon the exercise of a Nonqualified Stock Option, the Corporation shall
have the right to (i) require such Participant or such other person to pay by
cash or check payable to the Corporation, the amount of any taxes which the
Corporation may be required to withhold with respect to such transactions or
(ii) deduct from amounts paid in cash the amount of any taxes which the
Corporation may be required to withhold with respect to such cash amounts. The
above notwithstanding, in any case where a tax is required to be withheld in
connection with the issuance or transfer of shares of Common Stock under this
Plan, the Participant may elect, pursuant to such rules as the Committee may
establish, to have


                                       9

the Corporation reduce the number of such shares issued or transferred by the
appropriate number of shares to accomplish such withholding; provided, the
Committee may impose such conditions on the payment of any withholding
obligation as may be required to satisfy applicable regulatory requirements.

         (b) The Committee may, in its discretion, permit a loan from the
Corporation to a Participant in the amount of any taxes which the Corporation
may be required to withhold with respect to shares of Common Stock received
pursuant to a transaction described in subsection (a) above. Such a loan will be
for a term, at a rate of interest and pursuant to such other terms and rules as
the Committee may establish.

         3.7 Amendment, Termination and Suspension.

         (a) The Board may, at any time, terminate or, from time to time, amend,
modify or suspend this Plan, in whole or in part. No Options may be granted
during the suspension of this Plan or after termination of this Plan, but the
Committee shall retain jurisdiction as to Options then outstanding in accordance
with the terms of this Plan.

         (b) No amendment to the Plan shall be required to be submitted to the
stockholders of the Corporation for their approval unless such stockholder
approval of the amendment is required pursuant to applicable law.

         (c) Without limiting any other express authority of the Committee
under, but subject to the express limits of, this Plan, the Committee by
agreement or resolution may waive conditions of or limitations on Options to
Eligible Persons that the Committee in the prior exercise of its discretion has
imposed, without the consent of a Participant, and may make other changes to the
terms and conditions of Options that do not affect, in any manner materially
adverse to the Participant, his or her rights and benefits under an Option.

         (d) Subject to Section 3.7(c), no amendment, suspension or termination
of this Plan or change of or affecting any outstanding Option shall, without
written consent of the Participant, affect in any manner materially adverse to
the Participant any rights or benefits of the Participant or obligations of the
Company under any Option granted under this Plan prior to the effective date of
such change. Changes contemplated by Section 3.2 or 3.3 shall not be deemed to
constitute changes or amendments requiring Participant consent under Section
3.7(c) or Section 3.7(d).

         3.8 Privileges of Stock Ownership; Nondistributive Intent.

         A Participant shall not be entitled to the privilege of stock ownership
as to any shares of Common Stock not actually issued to him or her. No
adjustment will be made for dividends or other rights as a shareholder for which
a record date is prior to the date of delivery of a certificate representing the
Shares. Upon the issuance and transfer of Shares to the Participant, unless a
registration statement is in effect under the Securities Act and applicable
state securities law, relating to such issued and transferred Common Stock and
there is available for delivery a prospectus meeting the requirements of Section
10 of the Securities Act, the Common Stock may be issued and transferred to the


                                       10
<PAGE>   13


Participant only if he or she represents and warrants in writing to the Company
that the Shares are being acquired for investment and not with a view to the
resale or distribution thereof. No Shares shall be issued and transferred unless
and until there shall have been full compliance with any then applicable
regulatory requirements (including those of exchanges upon which any Common
Stock of the Company may be listed).

         3.9 Effective Date of the Plan.

         This Plan shall be effective upon its approval by the Board (the
"EFFECTIVE DATE"), subject to approval by the shareholders of the Company within
twelve months from the date of such Board approval. This amendment to and
restatement of the Plan is effective as of May 2, 2000.

         3.10 Term of the Plan.

         Unless previously terminated by the Board, this Plan shall terminate at
the close of business on the day before the tenth anniversary of the Effective
Date, and no Options shall be granted under it thereafter. Unless otherwise
expressly provided in this Plan or in the applicable Option Agreement, any
Option theretofore granted may extend beyond such date, and all authority of the
Board and the Committee with respect to Options hereunder, including its
authority to amend an Option, shall continue in respect of outstanding Options
on that date.

         3.11 Governing Law.

         This Plan and the documents evidencing Options and all other related
documents shall be governed by, and construed in accordance with, the laws of
the State of Texas. If any provision shall be held by a court of competent
jurisdiction to be invalid and unenforceable, the remaining provisions of this
Plan shall continue to be fully effective.

         3.12 Captions.

         Captions and headings are given to the sections and subsections of this
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
this Plan or any provision thereof.

         3.13 Non-Exclusivity of Plan.

         Nothing in this Plan shall limit or be deemed to limit the authority of
the Board or the Committee to grant awards or to authorize any other
compensation, with or without reference to the Common Stock, under any other
plan or authority.
