salary of $400,000 (the "Base Salary"). The Board of Directors (or a committee
thereof) shall review the Employee's Base Salary no less than annually and, in
its discretion, may increase, but not decrease, the Base Salary based upon
relevant circumstances. If the Employee's Base Salary is increased at any time,
it may not thereafter be decreased below such amount. The Base Salary shall be
payable in equal semi-monthly installments or in accordance with the Company's

may be required by law and other deductions applied generally to employees of
the Company for insurance and other employee benefit plans.

      4.2   Bonus. In addition to the Base Salary, the Employee shall be
awarded, for each fiscal year until the Date of Termination, an annual bonus
(pursuant to a bonus or incentive plan maintained by the Company) in an amount
to be determined by the Board of Directors (or a committee thereof) based upon a
bonus program established for executives generally taking into account the
Employee's Base Salary and position (the "Bonus"). For the year 2002, such Bonus
shall be based upon: (i) the Company's achievement of targeted EBITDA and
average working capital versus sales and achievement of business goals
(together, the "Bonus Measures") as established by the Board of Directors in the
approved budget; (ii) if the Company achieves the targeted amounts for the Bonus
Measures, the Bonus shall be no less than 70% of the Employee's Base Salary; and
(iii) the Bonus shall be increased to the extent the Company's achievement of
the Bonus Measures exceeds the targeted amounts, to a maximum of 140% of the

                                      -3-

<PAGE>

Base Salary. Each Bonus shall be payable at a time to be determined by the Board
of Directors (or a committee thereof) in its sole discretion but no later than
thirty days after delivery to the Company of final financial statements
certified by its auditors. The Bonus Measures and percentages of Base Salary
used in 2002 shall be used as Bonus Measures and percentages of Base Salary for
future Bonus years unless such Bonus Measures and percentages of Base Salary are
changed or altered for participating executives generally by the Board in
advance of the applicable future Bonus year.

      4.3   Stock Options. The Employee shall be entitled to receive grants of
stock options when awarded to executives generally in amounts and on terms
commensurate with his position, as determined from time to time by the Board of
Directors acting in good faith subject to the terms of the applicable stock
option plan and agreement.

      4.4   Vacation. Until the Date of Termination, the Employee shall be
entitled to paid vacation during each one year period in accordance with the

year period will not accrue and will expire on the applicable anniversary of the
Effective Date.

      4.5   Incentive, Savings and Retirement Plans. Until the Date of
Termination, the Employee shall be eligible to participate in and shall receive
all benefits under all executive incentive, savings and retirement plans and
programs currently maintained or hereinafter established by the Company for the
benefit of its executive officers and/or employees subject to the terms and
conditions contained in the governing documents of such plans.

      4.6   Welfare Benefit Plans. Until the Date of Termination, the Employee
and/or the Employee's family, as the case may be, shall be eligible to
participate in and shall receive all benefits under each welfare benefit plan of
the Company currently maintained or hereinafter established by the Company for
the benefit of its employees subject to the terms and conditions contained in
the governing documents of such plans. Such welfare benefit plans may include,
without limitation, medical, dental, disability, group life, accidental death
and travel accident insurance plans and programs.

      4.7   Automobile. The Company shall provide Employee with an automobile,
of the quality as in effect on the date of this Agreement and to be updated in
accordance with the Company's procedures for employees generally, for business
and personal use and shall pay all reasonable use and maintenance costs related
to such automobile, including, but not limited to, gasoline, oil, tires,
repairs, maintenance, and insurance.

      4.8   Reimbursement of Expenses. The Employee may from time to time until
the Date of Termination incur various business expenses customarily incurred by
persons holding positions of like responsibility, including, without limitation,
travel, entertainment and similar expenses incurred for the benefit of the
Company. Subject to the Company's policy regarding the reimbursement of such
expenses as in effect from time to time during the Employment Period, which does
not necessarily allow reimbursement of all such expenses, the Company shall
reimburse the Employee for such expenses from time to time, at the Employee's
request, and the Employee shall account to the Company for all such expenses.

regulations of the Company, or (B) in improper conduct which would result in a
material injury to the business, condition (financial or otherwise), results of
operations or prospects of the Company or its Affiliates (as determined in good
faith by the Board of Directors of the Company or a committee thereof);
provided, however, that no termination pursuant to clause (ii) or (iii) hereof
shall become effective unless Employee shall have failed to cure such Cause to
the satisfaction of the Board of Directors of the Company in their sole
discretion within thirty (30) days after receiving a Notice of Termination
detailing the alleged Cause.

      5.4   Without Cause. The Company may terminate this Agreement Without
Cause, upon written notice to the Employee delivered in accordance with Sections

of this Agreement, a "Notice of Termination" means a written notice which (i)
indicates the specific termination provision in this Agreement relied upon, (ii)
sets forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination of the Employee's employment under the provision so

6.    Obligations of Company upon Termination.

      6.1   Cause; Death or Voluntary Termination by Employee. If this
Agreement shall be terminated either by the Company for Cause, or as a result of
the Employee's death or Voluntary Termination by Employee, or expiration of the

application of the Automatic Extension described in Section 3 not yet in effect
with premiums to be paid by Employee at the same rate paid by employees who have
not been terminated and such period of coverage shall be offset by any period of
group health continuation coverage required under the Consolidated Omnibus
Budget Reconciliation Act of 1985, as amended ("COBRA"); and (iv) an amount,
payable pro rata over a period of 18 months, equal to the sum of (A) the lesser

                                      -6-

immediate preceding full year. All amounts shall be paid in accordance with the
Company's normal payroll practices and subject to applicable federal, state and
local taxes.

         6.3   After a Change in Control: Without Cause, Disability or for Good

within ten days following the applicable Date of Termination of an amount equal
to the sum of (A) three times the base salary as in effect on the Date of
Termination and (B) three times the highest Bonus received in any one of the
three years preceding the Date of Termination. All amounts shall be subject to
applicable federal, state and local taxes, and (excepting payment pursuant to
clause (iv)) paid in accordance with the Company's normal payroll practices.

         6.4   Change in Control; Requirement of an Additional Payment in
Certain Circumstances.

               (a)   In the event that Employee is deemed to have received an
         "excess parachute payment" (as defined in Section 280G(b) of the Code)
         which is subject to the excise taxes (the "Excise Taxes") imposed by
         Section 4999 of the Code in respect of any payment pursuant to this
         Agreement or any other agreement, plan, instrument or obligation, in
         whatever form, the Company shall make the Additional Payment (defined
         below) to Employee notwithstanding any contrary provision in this
         Agreement or any other agreement, plan, instrument or obligation.

               (b)   The term "Additional Payment" means a cash payment in an
         amount equal to the sum of (i) all Excise Taxes payable by Employee,
         plus (ii) all additional Excise Taxes and federal or state income taxes
         to the extent such taxes are imposed in respect of the Additional
         Payment, such that Employee shall be in the same after-tax position and
         shall have received the same benefits that he would have received if
         the Excise Taxes had not been imposed. For purposes of calculating any
         income taxes attributable to the Additional Payment, Employee shall be
         deemed for all purposes to be paying income taxes at the highest
         marginal federal income tax rate, taking into account any applicable
         surtaxes and other generally applicable taxes which have the effect of
         increasing the marginal federal income tax rate and, if applicable, at
         the highest marginal state income tax rate, to which the Additional
         Payment and Employee are subject. An example of the calculation of the
         Additional Payment is set forth below. Assume that the Excise Tax rate
         is 20%, the highest federal marginal income tax rate is 40% and
         Employee is not subject to state income taxes. Further assume that
         Employee has received an excess parachute payment in the amount of
         $200,000, on which $40,000 ($200,000 x 20%) in

                                       -7-

<PAGE>

         Excise Taxes are payable. The amount of the required Additional Payment
         is thus computed to be $100,000, i.e., the Additional Payment of
         $100,000, less additional Excise Taxes on the Additional Payment of
         $20,000 (i.e., 20% x $100,000) and income taxes of $40,000 (i.e., 40% x
         $100,000), yields $40,000, the amount of the Excise Taxes payable in
         respect of the original excess parachute payment.

               (c)   Employee agrees to reasonably cooperate with the Company to
         minimize the amount of the excess parachute payments, including,
         without limitation, assisting the Company in establishing that some or
         all of the payments received by Employee that are "contingent on a
         change," as described in Section 280G(b)(2)(A)(i) of the Code, are
         reasonable compensation for personal services actually rendered by
         Employee before the date of such change or to be rendered by Employee
         on or after the date of such change. In the event that the Company is
         able to establish that the amount of the excess parachute payments is
         less than originally anticipated by Employee, Employee shall refund to
         the Company any excess Additional Payment to the extent not required to
         pay Excise Taxes or income taxes (including those incurred in respect
         of receipt of the Additional Payment). Notwithstanding the foregoing,
         Employee shall not be required to take any action which his attorney or
         tax advisor advises him in writing (i) is improper or (ii) exposes
         Employee to personal liability. Employee may require the Company to
         deliver to Employee an indemnification agreement in form and substance
         reasonably satisfactory to Employee as a condition to taking any action
         required by this subsection (c).

               (d)   The Company shall make any payment required to be made
         under this Section 6.4 in a cash lump sum after the date on which
         Employee received or is deemed to have received any such excess
         parachute payment. Any payment required to be paid by the Company under
         this Section 6.4 which is not paid within 30 days of receipt by the
         Company of Employee's written demand therefor shall thereafter be
         deemed delinquent, and the Company shall pay to Employee immediately
         upon demand interest at the highest nonusurious rate per annum allowed
         by applicable law from the date such payment becomes delinquent to the
         date of payment of such delinquent sum with interest.

               (e)   In the event that there is any change to the Code which
         results in the recodification of Section 280G or Section 4999 of the
         Code, or in the event that either such section of the Code is amended,
         replaced or supplemented by other provisions of the Code of similar
         import ("Successor Provisions"), then this Agreement shall be applied
         and enforced with respect to such new Code provisions in a manner
         consistent with the intent of the parties as expressed herein, which is
         to assure that Employee is in the same after-tax position and has
         received the same benefits that he would have been in and received if
         any taxes imposed by Section 4999 (or any Successor Provisions) had not
         been imposed.

               (f)   All determinations required to be made under this Section
         6.4 including, without limitation, whether and when a Additional
         Payment is required, and the amount of such Additional Payment and the
         assumptions to be utilized in arriving at such determinations, unless
         otherwise expressly set forth in this Agreement, shall be made within
         30 days from the Change in Control Date by the independent tax
         consultant(s) selected by the Company and reasonably acceptable to
         Employee ("Tax Consultant").

                                       -8-

<PAGE>

         The Tax Consultant must be a qualified tax attorney or certified public
         accountant. All fees and expenses of the Tax Consultant shall be paid
         in full by the Company. Any Excise Taxes as determined pursuant to this
         Section 6.4 shall be paid by the Company to the Internal Revenue
         Service or any other appropriate taxing authority on Employee's behalf
         within five (5) business days after receipt of the Tax Consultant's
         final determination to Company and Employee.

               (g)   If the Tax Consultant determines that there is substantial
         authority (within the meaning of Section 6662 of the Code) that no
         Excise Taxes are payable by Employee, the Tax Consultant shall furnish
         Employee with a written opinion that failure to disclose or report the
         Excise Taxes on Employee's federal income tax return will not
         constitute a substantial understatement of tax or be reasonably likely
         to result in the imposition of a negligence or any other penalty.

               (h)   The Company shall indemnify and hold harmless the Employee,
         on an after-tax basis, from any costs, expenses, penalties, fines,
         interest or other liabilities ("Losses") incurred by Employee with
         respect to the exercise by the Company of any of its rights under this
         Section 6.4, including, without limitation, any Losses related to the
         Company's decision to contest a claim of any imputed income to
         Employee. The Company shall pay all fees and expenses incurred under
         this Section 6.4, and shall promptly reimburse Employee for the
         reasonable expenses incurred by Employee in connection with any actions
         taken by the Company or required to be taken by Employee hereunder. Any
         payments owing to Employee and not made within 30 days of delivery to
         the Company of evidence of Employee's entitlement thereto shall be paid
         to Employee together with interest at the maximum nonusurious rate
         permitted by law.

7.       Employee's Obligation to Avoid Conflicts of Interest.

         7.1   In keeping with the Employee's fiduciary duties to the Company
and in addition to the Company's policies and procedures regarding conflicts of
interest, the Employee agrees that he shall not knowingly during the term of his
employment hereunder become involved in a conflict of interest with the Company,
or upon discovery thereof, allow such a conflict to continue. The Employee
further agrees to disclose to the Company, promptly after discovery, any facts
or circumstances which might involve a conflict of interest with the Company.

         7.2   The Company and the Employee recognize that it is impossible to
provide an exhaustive list of actions or interests which constitute a "conflict
of interest." Moreover, the Company and the Employee recognize that there are
many borderline situations. In some instances, full disclosure of facts by the
Employee to the Company is all that is necessary to enable the Company to
protect its interests. In others, if no improper motivation appears to exist and
the Company's interests have not suffered, prompt elimination of the outside
interest will suffice. In still others, it may be necessary for the Company to
terminate the employment relationship.

         7.3   In this connection, it is agreed that any direct or indirect
interest in, connection with or benefit from any outside activities,
particularly commercial activities, which interest might in any way adversely
affect the Company or its Affiliates, involves a possible conflict of

                                       -9-

<PAGE>

interest; provided, however, that the Company acknowledges that Employee is a
director of Wembley Limited and the Employee's provision of such services to
Wembley Limited is acceptable to the Company as long as such services do not
result in a conflict of interest. Circumstances in which a conflict of interest
on the part of the Employee would or might arise, and which should be reported
immediately to the Company, include, but are not limited to, the following:

               (a)   Ownership of a material interest in any lender, supplier,
         contractor, subcontractor, customer or other entity with which the
         Company does business.

               (b)   Acting in any capacity, including director, officer,
         partner, consultant, employee, distributor, agent or the like, for any
         lender, supplier, contractor, subcontractor, customer or other entity
         with which the Company does business.

               (c)   Acceptance, directly or indirectly, of payments, services
         or loans from a lender, supplier, contractor, subcontractor, customer
         or other entity with which the Company does business, including,
         without limitation, gifts, trips, entertainment or other favors of more
         than a nominal value, but excluding loans from publicly held insurance
         companies and commercial or savings banks at market rates of interest.

               (d)   Improper use of information or facilities to which the
         Employee has access in a manner which will be detrimental to the
         Company's interests, such as use for the Employee's own benefit of
         know-how or information developed through the Company's business
         activities.

               (e)   Improper disclosure or other misuse of information of any
         kind obtained through the Employee's connection with the Company.

               (f)   Acquiring or trading in, directly or indirectly, other
         properties or interests connected with the design or marketing of
         products or services designed or marketed by the Company.

8.       Employee's Confidentiality Obligation.

         8.1   (a)   Employee acknowledges that his employment hereunder gives
him access to Confidential Information relating to the business of the Company,
its Affiliates and their customers that must remain confidential. Employee
acknowledges that this information is valuable, special, and a unique asset of
the business of the Company and its Affiliates, and that it has been and will be
developed by the Company and its Affiliates at considerable effort and expense,
and if it were to be known and used by others engaged in a Competitive Business,
it would be harmful and detrimental to the interests of the Company and its
Affiliates. In consideration of the foregoing, Employee hereby agrees and
covenants that, during and after the Employment Period, Employee will not,
directly or indirectly in one or a series of transactions, disclose to any
person, or use or otherwise exploit for Employee's own benefit or for the
benefit of anyone other than the Company or its Affiliates, Confidential
Information (as defined in Section 8.2) whether prepared by Employee or not;
provided, however, that any Confidential Information may be disclosed (i) to
officers, representatives, employees and agents of the

                                      -10-

<PAGE>

Company and its Affiliates who need to know such Confidential Information in
order to perform the services or conduct the operations required or expected of
them in the business of the Company or its Affiliates, or (ii) otherwise in
connection with Employee's performance of his duties hereunder on behalf of the
Company. Employee shall not remove any Confidential Information from the
premises of the Company and its Affiliates, except as required in his normal
course of employment by the Company. Employee shall instruct all persons or
entities to whom any Confidential Information shall be disclosed by him
hereunder to observe the terms and conditions set forth herein as though each
such person or entity was bound hereby. Employee shall have no obligation
hereunder to keep confidential any Confidential Information if and to the extent
disclosure of any thereof is specifically required by law; provided, however,
that in the event disclosure is required by applicable law, Employee shall
provide the Company with prompt notice of such requirement, if practicable,
prior to making any disclosure, so that the Company may seek an appropriate
protective order. At the request of the Company, Employee agrees to deliver to
the Company, at any time during the Employment Period, or thereafter, all
Confidential Information which he may possess or control. Employee agrees that
all Confidential Information of the Company (whether now or hereafter existing)
conceived, discovered or made by him during the Employment Period exclusively
belongs to the Company (and not to Employee). Executive will promptly disclose
such Confidential Information to the Company and perform all actions reasonably
requested by the Company to establish and confirm such exclusive ownership.

         (b)   In the event that Employee breaches his obligations in any
material respect under this Section 8, the Company, in addition to pursuing all
available remedies under this Agreement, at law or otherwise, including but not
limited to an injunction, and without limiting its right to pursue the same
shall cease all payments and benefits to Employee under Section 6 of this
Agreement.

         (c)   The terms of this Section 8 shall survive the termination of this
Agreement regardless of who terminates this Agreement, or the reasons therefor.

         8.2   "Confidential Information" means information, which is used in
the business of the Company or its Affiliates and (i) is proprietary to, about
or created by the Company or its Affiliates, (ii) gives the Company or its
Affiliates some competitive business advantage or the opportunity of obtaining
such advantage or the disclosure of which could be detrimental to the interests
of the Company or its Affiliates, or (iii) is designated as Confidential
Information by the Company or its Affiliates, is known by the Employee to be
considered confidential by the Company or its Affiliates, or from all the
relevant circumstances should reasonably be assumed by the Employee to be
confidential and proprietary to the Company or its Affiliates, and (iv) is not
generally known by non-Company personnel. Such Confidential Information
includes, without limitation, the following types of information and other
information of a similar nature (whether or not reduced to writing or designated
as confidential):

               (a)   Internal personnel and financial information of the Company
         or its Affiliates, vendor information (including vendor
         characteristics, services, prices, lists and agreements), purchasing
         and internal cost information, internal service and operational
         manuals, and the manner and methods of conducting the business of the
         Company or its Affiliates;

                                      -11-

<PAGE>

          (b) Marketing and development plans, price and cost data, price and
     fee amounts, pricing and billing policies, quoting procedures, marketing
     and sales techniques, forecasts and forecast assumptions and volumes, and
     future plans and potential strategies (including, without limitation, all
     information relating to any acquisition prospect and the identity of any
     key contact within the organization of any acquisition prospect) of the
     Company or its Affiliates which have been or are being discussed;

          (c) Names of customers and their representatives, contracts (including
     their contents and parties), customer services, and the type, quantity,
     specifications and content of products and services purchased, leased,
     licensed or received by customers of the Company or its Affiliates;

          (d) Confidential and proprietary information provided to the Company
     or its Affiliates by any actual or potential customer, government agency or
     other third party (including businesses, consultants and other entities and
     individuals).

          (e) Any trade secret, confidential study, data, calculations, software
     storage media or other compilation of information, patent, patent
     application, copyright, trademark, trade name, service mark, service name,
     "know-how" and trade secrets; and

          (f) Business acquisition plans or any portion or phase of any
     scientific or technical information, ideas, discoveries, designs, computer
     programs (including source of object codes), processes, procedures,
     research or technical data, improvements or other proprietary or
     intellectual property of the Company or its Affiliates, whether or not in
     written or tangible form, and whether or not registered, and including all
     files, records, manuals, books, catalogues, memoranda, notes, summaries,
     plans, reports, records, documents and other evidence thereof.

     8.3  As a consequence of the Employee's acquisition or anticipated
acquisition of Confidential Information, the Employee shall occupy a position of
trust and confidence with respect to the affairs and business of the Company and
its Affiliates. In view of the foregoing and of the consideration to be provided
to the Employee, the Employee agrees that it is reasonable and necessary that
the Employee make each of the following covenants:

          (a) At any time during the Employment Period and thereafter, the
     Employee shall not disclose Confidential Information to any person or
     entity, either inside or outside of the Company and its Affiliates, other
     than as necessary in carrying out his duties and responsibilities as set
     forth in Section 2 hereof, without first obtaining the Company's prior
     written consent (unless such disclosure is compelled pursuant to court
     orders or subpoena, and at which time the Employee shall give notice of
     such proceedings to the Company).

          (b) At any time during the Employment Period and thereafter, the
     Employee shall not use, copy or transfer Confidential Information other
     than as necessary in carrying out his duties and responsibilities as set
     forth in Section 2 hereof, without first obtaining the Company's prior
     written consent.

                                      -12-

<PAGE>

          (c) On the Date of Termination, the Employee shall promptly deliver to
     the Company (or its designee) all written materials, records and documents
     made by the Employee or which came into his possession prior to or during
     the Employment Period concerning the business or affairs of the Company or
     its Affiliates, including, without limitation, all materials containing
     Confidential Information.

9.   Employee's Non-Competition Obligation.

     9.1  Employee acknowledges that the services to be provided by him under
this Agreement give him the opportunity to have special knowledge of the Company
and its Confidential Information and the capabilities of individuals employed by
or affiliated with the Company, and that interference in these relationships
would cause irreparable injury to the Company. In consideration of this
Agreement, including but not limited to, the amounts payable by the Company upon
termination of Employee Without Cause, Employee covenants and agrees that:

          (a) During the Restricted Period, Employee will not, without the
     express written approval of the Board of Directors of the Company, anywhere
     in the Market, directly or indirectly, in one or a series of transactions,
     own, manage, operate, control, invest or acquire an interest in, or
     otherwise engage or participate in, whether as a proprietor, partner,
     stockholder, lender, director, officer, employee, joint venturer, investor,
     lessor, supplier, customer, agent, representative or other participant, in
     any Competitive Business without regard to (A) whether the Competitive
     Business has its office, manufacturing or other business facilities within
     or without the Market, (B) whether any of the activities of Employee
     referred to above occur or are performed within or without the Market or
     (C) whether Employee resides, or reports to an office, within or without
     the Market; provided, however, that (x) Employee may, anywhere in the
     Market, directly or indirectly, in one or a series of transactions, own,
     invest or acquire an interest in up to five percent (5%) of the capital
     stock of a Competitive Business whose capital stock is traded publicly, or
     that (y) Employee may accept employment with a successor company to the
     Company.

          (b) During the Restricted Period, Employee will not without the
     express prior written approval of the Board of Directors of the Company (A)
     directly or indirectly, in one or a series of transactions, recruit,
     solicit or otherwise induce or influence any proprietor, partner,
     stockholder, lender, director, officer, employee, sales agent, joint
     venturer, investor, lessor, supplier, customer, agent, representative or
     any other person which has a business relationship with any of the Company
     or had a business relationship with the Company within the twenty-four (24)
     month period preceding the date of the incident in question, to
     discontinue, reduce or modify such employment, agency or business
     relationship with the Company, or (B) employ or seek to employ or cause any
     Competitive Business to employ or seek to employ any person or agent who is
     then (or was at any time within six months prior to the date Employee or
     the Competitive Business employs or seeks to employ such person) employed
     or retained by the Company. Notwithstanding the foregoing, nothing herein
     shall prevent Company from providing a letter of recommendation to an
     employee with respect to a future employment opportunity.

                                      -13-

     earning a living with an entity that is not a Competitive Business.

     Agreement regardless of who terminates this Agreement, or the reasons
     therefor.

indirectly, with the Company's or an Affiliate's business in the Market.

          10.10 Arbitration.

                (a) If a dispute arises about whether Cause or Good Reason has
          occurred, the Employee's Termination Date shall be deferred until such
          dispute is resolved under American Arbitration Association commercial
          dispute resolution rules and procedures (the "Rules"). Any arbitration
          hereunder shall be conducted before a panel of three arbitrators
          unless the parties mutually agree that the arbitration shall be
          conducted before a single arbitrator. The arbitrators shall be
          selected (from lists provided by the AAA) through mutual agreement of
          the parties, if possible. If the parties fail to reach agreement upon
          appointment of arbitrators within twenty (20) days following receipt
          by one party of the other party's notice of desire to arbitrate, then
          within five (5) days following the end of such 20-day period, each
          party shall select one arbitrator who, in turn, shall within five (5)
          days jointly select the third arbitrator to comprise the arbitration
          panel hereunder. The site for any arbitration hereunder shall be in
          Harris County, Texas, unless otherwise mutually agreed by the parties,
          and the parties hereby waive any objection that the forum is
          inconvenient.

               (b) The party submitting any matter to arbitration shall do so in
          accordance with the Rules. Notice to the other party shall state the
          question or questions to be submitted for decision or award by
          arbitration.

               (c) The arbitrator shall set the date, time and place for each
          hearing, and shall give the parties advance written notice in
          accordance with the Rules. Any party may be represented by counsel or
          other authorized representative at any hearing. The arbitration shall
          be governed by the Federal Arbitration Act, 9 U.S.C. Sections 1 et.
          seq. (or its successor). The arbitrator shall apply the substantive
          law and the law of remedies, if applicable) of the State of Texas to
          the claims asserted to the extent that the arbitrator determines that
          federal law is not controlling.

               (d) (1) Any award of an arbitrator shall be final and binding
          upon the parties to such arbitration, and each party shall immediately
          make such changes in its conduct or provide such monetary payment or
          other relief as such award requires. The parties agree that the award
          of the arbitrator shall be final and binding and shall be subject only
          to the judicial review permitted by the Federal Arbitration Act; and
          (2) the

                                      -16-

<PAGE>

         parties hereto agree that the arbitration award may he entered with any
         court having jurisdiction and the award may then be enforced as between
         the parties, without further evidentiary proceedings, the same as if
         entered by the court at the conclusion of a judicial proceeding in
         which no appeal was taken. The Company and the Employee hereby agree
         that a judgment upon any award rendered by an arbitrator may be
         enforced in other jurisdictions by suit on the judgment or in any other
         manner provided by law.

                (e) Each party shall pay any monetary amount required by the
         arbitrator's award, and the fees, costs and expenses for its own
         counsel, witnesses and exhibits, unless otherwise determined by the
         arbitrator in the award. The compensation and costs and expenses
         assessed by the arbitrator(s) and the AAA shall be split evenly between
         the parties unless otherwise determined by the arbitrator in the award.
         If court proceedings to stay litigation or compel arbitration are
         necessary, the party who opposes such proceedings to stay litigation or
         compel arbitration, if such party is unsuccessful, shall pay all
         associated costs, expenses, and attorney's fees which are reasonably
         incurred by the other party as determined by the arbitrator.

         10.11 Attorney's Fees. Except as otherwise provided herein, Employee's
reasonable attorneys' fees actually incurred in connection with negotiating
and/or enforcing this Agreement shall be paid by the Company.

          IN WITNESS WHEREOF, the undersigned, intending to be legally bound,
have executed this Agreement as of the date first written above.
