or engage in charitable, civic, and/or governmental activities provided that
such service and activities do not prevent Executive from performing the duties

hereunder and/or the provisions of Executive's written agreements with the

committee shall review this Agreement to determine whether any changes or

                  AND INVENTIONS.

                  This Agreement, and Executive's employment hereunder, is

prior to this Agreement.

written or oral, concerning Executive's term of employment with the Company. The
at-will nature of Executive's employment may only be altered by written
agreement signed by the Company's Chairman and Treasurer.

discussions and agreements among the parties with respect to the subject matter
hereof and contain the sole and entire agreement between the parties hereto with
respect thereto.

                  4.5 WAIVER. Any term or condition of this Agreement may be
waived at any time by the party that is entitled to the benefit thereof, but no
such waiver shall be effective unless set forth in a written instrument duly

cumulative and not alternative.

                  4.6 AMENDMENT. This Agreement may be amended, supplemented, or

                  4.7 BINDING ARBITRATION. Subject to the exceptions set forth

between Executive and the Company, or any of its employees, managers,
supervisors or agents, which arise out of Executive's employment or under the
terms of Executive's employment, shall be resolved through final and binding
arbitration, as specified herein. This shall include, without limitation,
disputes relating to this Agreement, Executive's employment by the Company, or
the termination thereof, claims for breach of contract or breach of the covenant
of good faith and fair dealing, and any claims of discrimination or other claims
under Title VII of the Civil Rights Act of 1964, the Age Discrimination in
Employment Act, the Americans with

                                       3
<PAGE>   4

Disabilities Act, the Family and Medical Leave Act, the Texas Commission on
Human Rights Act, the Employee Retirement Income Securities Act, the Racketeer
Influenced and Corrupt Organization Act, or any other federal, state or local
law or regulation now in existence or hereinafter enacted and as amended from
time to time concerning in any way the subject of Executive's employment with
the Company or its termination. The only claims or disputes not covered by this
paragraph are disputes related to (i) claims for benefits under the unemployment
insurance or workers' compensation laws; (ii) issues affecting the validity,
infringement or enforceability of any trade secret or patent rights held or
sought by the Company or which the Company could otherwise seek; or (iii) claims
by the Company to enforce, through injunctive relief or otherwise, violations of
the Confidentiality, Proprietary Information and Inventions Agreement signed by
Executive. In each of these three exceptions, such claims or disputes shall not
be subject to arbitration and will be resolved pursuant to applicable law.
Binding arbitration will be conducted in accordance with the Code of Arbitration
Procedure of the National Association of Securities Dealers ("NASD"). Each party
will split the cost of the arbitration filing and hearing fees, and the cost of
the arbitrator. Executive and the Company understand and agree that the
arbitration shall be instead of any jury trial and that arbitrator's decision
shall be final and binding to the fullest extent permitted by law and
enforceable by any court having jurisdiction thereof. The prevailing party shall
be entitled to recover, from the non-prevailing party, the prevailing party's
costs and reasonable attorney's fees, in addition to all other legal or
equitable remedies to which it may otherwise be entitled.

                  4.8 NO THIRD PARTY BENEFICIARY. The terms and provisions of
this Agreement are intended solely for the benefit of each party hereto and the
Company's successors or assigns, and it is not the intention of the parties to
confer third-party beneficiary rights upon any other person.

                  4.9 NO ASSIGNMENT; BINDING EFFECT. This Agreement shall inure
to the benefit of any successors or assigns of the Company. Executive shall not
be entitled to assign his obligations under this Agreement.

                  4.10 HEADINGS. The headings used in this Agreement have been
inserted for convenience of reference only and do not define or limit the
provisions hereof.

                  4.11 SEVERABILITY. The Company and Executive intend all
provisions of this Agreement to be enforced to the fullest extent permitted by
law. Accordingly, if an arbitrator or court of competent jurisdiction, if
applicable, determines that the scope and/or operation of any provision of this
Agreement is too broad to be enforced as written, the Company and Executive
intend that the court should reform such provision to such narrower scope and/or
operation as it determines to be enforceable. If, however, any provision of this
Agreement is held to be illegal, invalid, or unenforceable under present or
future law, and not subject to reformation, then (i) such provision shall be
fully severable, (ii) this Agreement shall be construed and enforced as if such
provision was never a part of this Agreement, and (iii) the remaining provisions
of this Agreement shall remain in full force and effect and shall not be
affected by illegal, invalid, or unenforceable provisions or by their severance.

                  4.12 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS APPLICABLE TO
CONTRACTS EXECUTED AND PERFORMED IN SUCH STATE WITHOUT GIVING EFFECT TO
CONFLICTS OF LAWS PRINCIPLES.

                  4.13 JURISDICTION. With respect to any suit, action, or other
proceeding arising from (or relating to) this Agreement to which the arbitration
provisions of 4.7 do not apply, the Company and Executive hereby irrevocably
agree to the non-exclusive personal jurisdiction and venue of the United States
District Court for the Northern District of Texas (and any Texas State Court
within Dallas County, Texas).

this Section 4.2, be deemed given upon receipt (in each case regardless of
whether such notice, request, or other communication is received by any other
person to whom a copy of such notice, request or other communication is to be
delivered pursuant to this Section). Any party from time to time may change its
address, facsimile number, or other information for the purpose of notices to
that party by giving written notice specifying such change to the other parties
hereto.

                  4.3 AUTHORIZATION TO BE EMPLOYED. This Agreement, and
Executive's employment hereunder, is subject to Executive providing the Company
with legally required proof of Executive's authorization to be employed in the
United States of America.

                  4.4 ENTIRE AGREEMENT. This Agreement supersedes all prior
discussions and agreements among the parties with respect to the subject matter
hereof and contain the sole and entire agreement between the parties hereto with
respect thereto.

                  4.5 WAIVER. Any term or condition of this Agreement may be
waived at any time by the party that is entitled to the benefit thereof, but no
such waiver shall be effective unless set forth in a written instrument duly
executed by or on behalf of the party waiving such term or condition. No waiver
by any party hereto of any term or condition of this Agreement, in any one or
more instances, shall be deemed to be or construed as a waiver of the same or
any other term or condition of this Agreement on any future occasion. All
remedies, either under this Agreement or by law or otherwise afforded, will be
cumulative and not alternative.

                  4.6 AMENDMENT. This Agreement may be amended, supplemented, or
modified only by a written instrument duly executed by or on behalf of each
party hereto.

                  4.7 BINDING ARBITRATION. Subject to the exceptions set forth
below, Executive and the Company agree that any and all claims or disputes
between Executive and the Company, or any of its employees, managers,
supervisors or agents, which arise out of Executive's employment or under the
terms of Executive's employment, shall be resolved through final and binding
arbitration, as specified herein. This shall include, without limitation,
disputes relating to this Agreement, Executive's employment by the Company, or
the termination thereof, claims for breach of contract or breach of the covenant
of good faith and fair dealing, and any claims of discrimination or other claims
under Title VII of the Civil Rights Act of 1964, the Age Discrimination in
Employment Act, the Americans with

Disabilities Act, the Family and Medical Leave Act, the Texas Commission on
Human Rights Act, the Employee Retirement Income Securities Act, the Racketeer
Influenced and Corrupt Organizations Act, or any other federal, state or local
law or regulation now in existence or hereinafter enacted and as amended from
time to time concerning in any way the subject of Executive's employment with
the Company or its termination. The only claims or disputes not covered by this
paragraph are disputes related to (i) claims for benefits under the unemployment
insurance or workers' compensation laws; (ii) issues affecting the validity,
infringement or enforceability of any trade secret or patent rights held or
sought by the Company or which the Company could otherwise seek; or (iii) claims
by the Company to enforce, through injunctive relief or otherwise, violations of
the Confidentiality, Proprietary Information and Inventions Agreement signed by
Executive. In each of these three exceptions, such claims or disputes shall not
be subject to arbitration and will be resolved pursuant to applicable law.
Binding arbitration will be conducted in accordance with the Code of Arbitration
Procedure of the National Association of Securities Dealers ("NASD"). Each party
will split the cost of the arbitration filing and hearing fees, and the cost of
the arbitrator. Executive and the Company understand and agree that the
arbitration shall be instead of any jury trial, and that the arbitrator's
decision shall be final and binding to the fullest extent permitted by law and
enforceable by any court having jurisdiction thereof. The prevailing party shall
be entitled to recover, from the non-prevailing party, the prevailing party's
costs and reasonable attorney's fees, in addition to all other legal or
equitable remedies to which it may otherwise be entitled.

                  4.8 NO THIRD PARTY BENEFICIARY. The terms and provisions of
this Agreement are intended solely for the benefit of each party hereto and the
Company's successors or assigns, and it is not the intention of the parties to
confer third-party beneficiary rights upon any other person.

                  4.9 NO ASSIGNMENT; BINDING EFFECT. This Agreement shall inure
to the benefit of any successors or assigns of the Company. Executive shall not
be entitled to assign his obligations under this Agreement.

                  4.10 HEADINGS. The headings used in this Agreement have been
inserted for convenience of reference only and do not define or limit the
provisions hereof.

                  4.11 SEVERABILITY. The Company and Executive intend all
provisions of this Agreement to be enforced to the fullest extent permitted by
law. Accordingly, if an arbitrator or court of competent jurisdiction, as
applicable, determines that the scope and/or operation of any provision of this
Agreement is too broad to be enforced as written, the Company and Executive
intend that the court should reform such provision to such narrower scope and/or
operation as it determines to be enforceable. If, however, any provision of this
Agreement is held to be illegal, invalid, or unenforceable under present or
future law, and not subject to reformation, then (i) such provision shall be
fully severable, (ii) this Agreement shall be construed and enforced as if such
provision was never a part of this Agreement, and (iii) the remaining provisions
of this Agreement shall remain in full force and effect and shall not be
affected by illegal, invalid, or unenforceable provisions or by their severance.

                  4.12 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS APPLICABLE TO
CONTRACTS EXECUTED AND PERFORMED IN SUCH STATE WITHOUT GIVING EFFECT TO
CONFLICTS OF LAWS PRINCIPLES.

                  4.13 JURISDICTION. With respect to any suit, action, or other
proceeding arising from (or relating to) this Agreement to which the arbitration
provisions of 4.7 do not apply, the Company and Executive hereby irrevocably
agree to the non-exclusive personal jurisdiction and venue of the United States
District Court for the Northern District of Texas (and any Texas State Court
within Dallas County, Texas).
