         (c) Additional Benefits.  In addition to the other compensation payable
             -------------------
to the Employee hereunder, and to the benefits set forth on Schedule 2 attached
                                                            ----------
hereto, during the Employment Term the Company shall provide the Employee with
such other benefits as may be approved by the Company's Board of Directors, and
will also permit the Employee to participate in any and all group life insurance
plans and medical and dental health benefit plans and the like and all other

previously

                                       2
<PAGE>

granted to Employee that are or become fully vested during the Employment Term
shall remain exercisable subject to the terms of the plan and option agreements
under which they were granted.

     5.  Expenses.  The Employee shall be reimbursed by the Company for all
         --------
reasonable expenses incurred by him in connection with the performance of his
duties hereunder.

     6.  Agreement Not to Compete.  The Employee agrees that during the Non-
         ------------------------
Competition Period (defined below) he will not in any capacity, either
separately, jointly, or in association with others, directly or indirectly, as
an officer, director, consultant, agent, employee, owner, partner, distributor,
dealer, representative, stockholder or otherwise, engage or have a financial
interest in any business located anywhere in the Restricted Area (as herein
defined) which competes with the Company or with any affiliate of the Company
(excepting only the ownership of not more than 5.0% of the outstanding
securities of any class listed on an exchange or regularly traded in the over-
the-counter market).  "Restricted Area" means the entire world.  An entity or
individual shall be deemed to compete with the Company or one of the Company's
affiliates as of a particular time if the entity or individual then
manufactures, produces, markets, distributes or sells any product or service
which is directly competitive with, or which may be purchased in replacement or
substitution of, any product or service which was being manufactured, produced,
marketed, distributed, sold or actively developed by the Company or such
affiliate during the Employment Term, and which is then still being
manufactured, produced, marketed, distributed, sold or actively developed by the
Company or such affiliate.  A product or service shall be deemed to be under
active development by the Company or its affiliate as of a particular date only
if the Company or such affiliate has devoted significant resources to the
development thereof and intends to market, distribute or sell such product or
service within the next 18 months of such date.  The "Non-Competition Period" is
the period beginning on the date of execution of this Agreement and ending on
March 1, 2003.  The Employee further agrees that during the Non-Competition
Period he will not in any capacity, either separately, jointly or in association
with others, directly or indirectly, solicit or otherwise contact any of the
Company's or its affiliates' customers, distributors, dealers or representatives
as shown by the Company's or its affiliates' records, that were customers,
distributors, dealers or representatives of the Company or its affiliates at any
time during the two years immediately preceding the date of termination of the
Employee's employment hereunder if such solicitation or contact is for the
specific purpose of selling products or services that compete with any products
or services that the Company or its affiliates had available for sale to its
customers, distributors, dealers, representatives or prospects during the two
years immediately preceding the end of the Non-Competition Period.  If a court
determines that the foregoing restrictions are too broad or otherwise
unreasonable under applicable law, including with respect to time or space, the
court is hereby requested and authorized by the parties hereto to revise the
foregoing restrictions to include the maximum restrictions allowed under the
applicable law.  The Employee expressly agrees that breach of the foregoing
would result in irreparable injuries to the Company and its affiliates, that the
remedy at law for any such breach will be inadequate and that upon breach of
this provision, the Company and its affiliates, in addition to all other
available remedies, shall be entitled as a matter of right to injunctive relief
in any court of competent jurisdiction without the necessity of proving the
actual damage to the Company or its affiliates.  For purposes of this

                                       3
<PAGE>

Section 6 and Section 7, an affiliate of the Company shall include any person or
entity directly or indirectly controlling (within the meaning of Rule 12b-2
under the Securities Exchange Act of 1934), or directly or indirectly controlled
by, or under direct or indirect common control with the Company.

     7.  Secret Processes and Confidential Information.  For the Employment Term
         ---------------------------------------------
and thereafter, (a) the Employee will not divulge, directly or indirectly, other
than in the regular and proper course of business of the Company or its
affiliates or as required by law, any confidential knowledge or information with
respect to the operation or finances of the Company or its affiliates or with
respect to confidential or secret processes, techniques, machinery, customers,
plans and products manufactured or sold by the Company or its affiliates
(collectively, "Confidential Information") and (b) the Employee will not use,
directly or indirectly, any Confidential Information for the benefit of anyone
other than the Company or its affiliates; provided, however, that the Employee
has no obligation, express or implied, to refrain from using or disclosing to
others any such knowledge or information which is or hereafter shall become
available to the public other than through disclosure by the Employee.  All new
processes, techniques, know-how, inventions, plans, products, patents and
devices developed, made or invented by the Employee, alone or with others, while
an employee of the Company or its affiliates, are hereby assigned to the Company
and shall become and be the sole property of the Company unless released in
writing by the Company. Notwithstanding the foregoing, if the Employee is
required to disclose or divulge Confidential Information pursuant to any
subpoena or other judicial process he will promptly so notify the Company, and
if so requested by the Company or its affiliates, will assist the Company or its
affiliates in seeking a protective order with respect thereto.  If the Company
cannot or chooses not to obtain such a protective order, the Employee will
divulge only such Confidential Information as he is advised by his counsel is
required to be disclosed, and will use his best efforts to ensure that the
balance of such Confidential Information will be kept confidential.

     8.  Termination.
         -----------

         (a)  Termination at End of Employment Term. Unless affirmatively
              -------------------------------------
extended by written agreement of the Company and the Employee, the employment of
the Employee hereunder shall terminate at the end of the Employment Term.

         (b)  Termination Prior to the End of the Employment Term.
              ---------------------------------------------------
Notwithstanding anything to the contrary except for "Cause" as defined below,
the Company may not terminate the Employee's employment prior to the end of the
Employment Term. In the event that the Company elects to terminate the
employment of the Employee for "Cause" prior to the end of the Employment Term,
or the Employee terminates his employment prior to the end of the Employment
Term, whether voluntarily, involuntarily, as a result of death, disability or
otherwise, then (i) the Employee shall be entitled to receive all Bonus
Compensation, and (ii) the Employee shall not be entitled to receive the
remaining amount of Salary Compensation, prorated for the portion of the
Employment Term not fulfilled. Termination for Cause shall be preceded by at
least forty-five (45) days' notice. Cause is hereby defined as:

                                       4
<PAGE>

               (A) Employee's conviction for a felony offense or commission by
          Employee of any act abhorrent to the community that the Company
          considers materially damaging to or tending to discredit the
          reputation of the Company;

               (B)  Dishonesty, fraud, willful misconduct, unlawful
          discrimination or theft on the part of Employee;

               (C)  Employee's public drunkenness, public use of illegal
          substances or drugs or the use, possession, distribution or being
          under the influence of alcohol or illegal substances or drugs in the
          workplace (the only exception is that Employee may consume alcohol
          reasonably and responsibly, if he or she so chooses, at legitimate
          business events and functions where alcohol is legally available); or

               (D)  The determination by the Company that Employee has
          continually failed or refused to comply, after notice of and a
          reasonable opportunity to cure such failure or refusal, with the terms
          or provisions of Section 6 or 7 of this Agreement, or the policies,
          standards, regulations, instructions, or directions of the Company as
          they currently exist or as they may be modified from time to time.

  9.      General Release.
          ---------------

          (a)  Employee General Release.  In consideration of the compensation
               ------------------------

Human Rights Act, the Texas Payday Act and the Age Discrimination in Employment
Act. The Employee understands and acknowledges that if, notwithstanding his

claims, the court hearing his claims may hold him liable for the damages and
costs,

including attorney's fees, incurred by the Company or the other Employee
Released Parties in defending such claims. This general release does not have

in any way from any act, omission or event from the beginning of time through
and including that date and time of this Agreement. This general release
includes, but is not limited to, any and all claims under the Employment
Agreement dated October 1, 1998, and any other employment agreement (other than
this Agreement). The Company understands and acknowledges that if,
notwithstanding its waiver of claims as described above, it should nonetheless
proceed to make such claims, the court hearing its claims may hold it liable for
the damages and costs, including attorney's fees, incurred by the Employee or
the other Company Released Parties in defending such claims. This general
release does not have any effect on any claim that the Company may have against
the Employee or any of the other Company Released Parties with respect to any
rights or claims that may arise as the result of acts, omissions or events after
the date and time of this Agreement or under any existing option agreements and
the related plan pursuant to which such options were granted.
