                                                                EXHIBIT 10.66(a)

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This Employment Agreement ("Agreement"), including the attached Exhibit
"A," is entered into between Enron Oil & Gas Company, a Delaware corporation,
having offices at 1400 Smith Street, Houston, Texas 77002 ("Employer"), and
Barry Hunsaker, Jr., an individual currently residing at 3730 Wickersham,
Houston, Texas 77027 ("Employee"), to be effective as of September 1, 1998 (the
"Effective Date").

                                   WITNESSETH:

         WHEREAS, Employer and Employee previously entered into a letter
agreement dated April 2, 1996; and

         WHEREAS, Employer is desirous of employing Employee pursuant to the
terms and conditions and for the consideration set forth in this Agreement, and
Employee is desirous of entering the employ of Employer pursuant to such terms
and conditions and for such consideration.

         NOW, THEREFORE, for and in consideration of the mutual promises,
covenants, and obligations contained herein, Employer and Employee agree as
follows:

ARTICLE 1: EMPLOYMENT AND DUTIES:

         1.1 Employer agrees to employ Employee, and Employee agrees to be
employed by Employer, beginning as of the Effective Date and continuing until
the date set forth on Exhibit "A" (the "Term"), subject to the terms and
conditions of this Agreement. This Agreement shall supercede and replace the
letter agreement dated April 2, 1996.

         1.2 Employee shall be employed in the position set forth on Exhibit A
in the Company's headquarters location. Employee agrees to serve in the assigned
position and to perform diligently and to the best of Employee's abilities the
duties and services appertaining to such position as determined by Employer, as
well as such additional or different duties and services appropriate to such
position which Employee from time to time may be reasonably directed to perform
by Employer. Employee shall at all times comply with and be subject to such
policies and procedures as Employer may establish from time to time.

         1.3 Employee shall, during the period of Employee's employment by
Employer, devote Employee's full business time, energy, and best efforts to the
business and affairs of Employer. Employee may not engage, directly or
indirectly, in any other business, investment, or activity that interferes with
Employee's performance of Employee's duties hereunder, is known to Employee to
be contrary to the interests of Employer or Enron Corp. ("Enron"), or requires
any significant portion of Employee's business time.

         1.4 In connection with Employee's employment by Employer, Employer
shall endeavor to provide Employee access to such confidential information
pertaining to the business and services of Employer as is appropriate for
Employee's employment responsibilities. Employer also shall endeavor to provide
to Employee the opportunity to develop business relationships with those of
Employer's clients and potential clients that are appropriate for Employee's
employment responsibilities.

         1.5 Employee acknowledges and agrees that, at all times during the
employment relationship Employee owes fiduciary duties to Employer, including
but not limited to the fiduciary duties of the highest loyalty, fidelity and
allegiance to act at all times in the best interests of the Employer, to make
full disclosure to Employer of all information that pertains to Employer's
business and interests, to do no act which Employee knows or should know would
injure Employer's business, its interests, or its reputation, and to refrain
from using for Employee's own benefit or for the benefit of others any
information or opportunities pertaining to Employer's business or interests that
are entrusted to Employee or that he learned while employed by Employer.
Employee acknowledges and agrees that upon termination of the employment
relationship, Employee shall continue to refrain from using for his own benefit
or the benefit of others any information or opportunities pertaining to
Employer's business or interests that were entrusted to Employee during the
employment relationship or that he learned while employed by Employer. Employee
agrees that while employed by Employer and thereafter he shall not knowingly
take any action which interferes with the internal relationships between
Employer and its employees or representatives or interferes with the external
relationships between Employer and third parties.

         1.6 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 Employer or any of
its affiliates, involves a possible conflict of interest. In keeping with
Employee's fiduciary duties to Employer, Employee agrees that during the
employment relationship Employee shall not knowingly become involved in a
conflict of interest with Employer or its affiliates, or upon discovery thereof,
allow such a conflict to continue. Moreover, Employee agrees that Employee shall
disclose to Employer's President any facts which might involve such a conflict
of interest that has not been approved by Employer's President. Employer and
Employee recognize that it is impossible to provide an exhaustive list of
actions or interests which constitute a "conflict of interest." Moreover,
Employer and Employee recognize there are many borderline situations. In some
instances, full disclosure of facts by the Employee to Employer's President may
be all that is necessary to enable Employer or its affiliates to protect its
interests. In others, if no improper motivation appears to exist and the
interests of Employer or its affiliates have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for
Employer to terminate the employment relationship. Employer and Employee agree
that Employer's determination as to whether a conflict of interest exists shall
be conclusive. Employer reserves the right to take such action as, in its
judgment, will end the conflict.

         1.7 Employee understands and acknowledges that the terms and conditions
of this Agreement constitute confidential information. Employee shall keep
confidential the terms of this Agreement and shall not disclose this
confidential information to anyone other than Employee's attorneys, tax
advisors, or as required by law. Employee acknowledges and understands that




                                       2
<PAGE>   3

disclosure of the terms of this Agreement constitutes a material breach of this
Agreement and could subject Employee to disciplinary action, including without
limitation, termination of employment.

ARTICLE 2: COMPENSATION AND BENEFITS:

         2.1 Employee's monthly base salary during the Term shall be not less
than the amount set forth under the heading "Monthly Base Salary" on Exhibit A,
subject to increase at the sole discretion of the Employer, but consistent with
increases provided to other similarly situated executives of Employer, which
shall be paid in semimonthly installments in accordance with Employer's standard
payroll practice. Any calculation to be made under this Agreement with respect
to Employee's Monthly Base Salary shall be made using the then current Monthly
Base Salary in effect at the time of the event for which such calculation is
made.

         2.2 While employed by Employer (both during the Term and thereafter),
Employee shall be allowed to participate, on the same basis generally as other
employees of Employer, in all general employee benefit plans and programs,
including improvements or modifications of the same, which on the effective date
or thereafter are made available by Employer to all or substantially all of
Employer's employees. Such benefits, plans, and programs may include, without
limitation, medical, health, and dental care, life insurance, disability
protection, and pension plans. Nothing in this Agreement is to be construed or
interpreted to provide greater rights, participation, coverage, or benefits
under such benefit plans or programs than provided to similarly situated
employees pursuant to the terms and conditions of such benefit plans and
programs. Notwithstanding, Employee shall be eligible for one week of vacation
in addition to the vacation provided under Employer's annual vacation policy.

         2.3 Employer shall not by reason of this Article 2 be obligated to
institute, maintain, or refrain from changing, amending, or discontinuing, any
such incentive compensation or employee benefit program or plan, so long as such
actions are similarly applicable to covered employees generally. Moreover,
unless specifically provided for in a written plan document adopted by the Board
of Directors of either Employer or Enron, none of the benefits or arrangements
described in this Article 2 shall be secured or funded in any way, and each
shall instead constitute an unfunded and unsecured promise to pay money in the
future exclusively from the general assets of Employer.

         2.4 Employer may withhold from any compensation, benefits, or amounts
payable under this Agreement all federal, state, city, or other taxes as may be
required pursuant to any law or governmental regulation or ruling.

ARTICLE 3: TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF SUCH
           TERMINATION:

         3.1. Notwithstanding any other provisions of this Agreement, Employer
shall have the right to terminate Employee's employment under this Agreement at
any time prior to the expiration of the Term for any of the following reasons:



                                       3
<PAGE>   4

         (i)      For "cause" upon the determination by the Employer's Board of
                  Directors or management committee (or, if there is no
                  management committee, the highest applicable level of
                  Employer's management) that "cause" exists for the termination
                  of the employment relationship. As used in this Section
                  3.1(i), the term "cause" shall mean [a] Employee's willful
                  misconduct in the performance of the duties and services
                  required of Employee pursuant to this Agreement; [b]
                  Employee's final conviction of a felony involving moral
                  turpitude; [c] Employee's willful refusal without proper legal
                  reason to perform the duties and responsibilities required of
                  Employee under this Agreement which remains uncorrected for
                  thirty (30) days following written notice to Employee by
                  Employer of such breach; [d] Employee's involvement in a
                  conflict of interest as referenced in Section 1.6 for which
                  Employer makes a determination to terminate the employment of
                  Employee which remains uncorrected for thirty (30) days
                  following written notice to Employee by Employer of such
                  breach; [e] Employee's willful engagement in conduct that
                  Employee knows or should know is materially injurious to
                  Employer, Enron, or any of their respective subsidiaries; [f]
                  Employee's material breach of any material provision of this
                  Agreement or corporate code or policy which remains
                  uncorrected for thirty (30) days following written notice to
                  Employee by Employer of such breach; or [g] Employee's
                  violation of the Foreign Corrupt Practices Act or other
                  applicable United States law as proscribed by Section 5.1. It
                  is expressly acknowledged and agreed that the decision as to
                  whether "cause" exists for termination of the employment
                  relationship by Employer is delegated to the Employer's
                  management committee (or, if there is no management committee,
                  the highest applicable level of Employer's management) for
                  determination. If Employee disagrees with the decision reached
                  by Employer's management committee (or, if there is no
                  management committee, the highest applicable level of
                  Employer's management), the dispute will be limited to whether
                  Employer's management committee (or, if there is no management
                  committee, the highest applicable level of Employer's
                  management) reached its decision in good faith;

         (ii)     for any other reason whatsoever, with or without cause, in the
                  sole discretion of the management committee (or, if there is
                  no management committee, the highest applicable level of
                  management) of Employer;

         (iii)    upon Employee's death; or

         (iv)     upon Employee's becoming disabled so as to entitle Employee to
                  benefits under Enron's long-term disability plan or, if
                  Employee is not eligible to participate in such plan, then
                  Employee is permanently and totally unable to perform
                  Employee's duties for Employer as a result of any medically
                  determinable physical or mental impairment as supported by a
                  written medical opinion to the foregoing effect by a physician
                  selected by Employer.

The termination of Employee's employment by Employer prior to the expiration of
the Term shall constitute a "Termination for Cause" if made pursuant to Section
3.1(i); the effect of such termination is specified in Section 3.4. The
termination of Employee's employment by Employer prior to the








                                       4
<PAGE>   5


expiration of the Term shall constitute an "Involuntary Termination" if made
pursuant to Section 3.1(ii); the effect of such termination is specified in
Section 3.5. The effect of the employment relationship being terminated pursuant
to Section 3.1(iii) as a result of Employee's death is specified in Section 3.6.
The effect of the employment relationship being terminated pursuant to Section
3.1(iv) as a result of the Employee becoming incapacitated is specified in
Section 3.7.

         3.2 Notwithstanding any other provisions of this Agreement except
Section 8.6, Employee shall have the right to terminate the employment
relationship under this Agreement at any time prior to the expiration of the
Term of employment for any of the following reasons:

         (i)      a material breach by Employer of any material provision of
                  this Agreement which remains uncorrected for 30 days following
                  written notice of such breach by Employee to Employer; or

         (ii)     for any other reason whatsoever, in the sole discretion of
                  Employee.

The termination of Employee's employment by Employee prior to the expiration of
the Term shall constitute an "Involuntary Termination" if made pursuant to
Section 3.2(i); the effect of such termination is specified in Section 3.5. The
termination of Employee's employment by Employee prior to the expiration of the
Term shall constitute a "Voluntary Termination" if made pursuant to Section
3.2(ii); the effect of such termination is specified in Section 3.3.

         3.3 Upon a "Voluntary Termination" of the employment relationship by
Employee prior to expiration of the Term, Employee shall be entitled to pro rata
salary through the date of such termination, but Employee shall not be entitled
to any individual bonuses or individual incentive compensation not yet paid at
the date of such termination.

         3.4 If Employee's employment hereunder shall be terminated by Employer
for Cause prior to expiration of the Term, Employee shall be entitled to pro
rata salary through the date of such termination, but Employee shall not be
entitled to any individual bonuses or individual incentive compensation not yet
paid at the date of such termination.

         3.5 Upon an Involuntary Termination of the employment relationship by
either Employer or Employee prior to the expiration of the Term, Employee shall
be entitled, in consideration of Employee's continuing obligations hereunder
after such termination (including, without limitation, Employee's
non-competition obligations), to receive the greater of a) 12 months of the then
current Monthly Base Salary or b) the then current Monthly Base Salary as if
Employee's employment (which shall cease on the date of such Involuntary
Termination) had continued for the full Term of this Agreement. If such
Involuntary Termination occurs within two years after a Change of Control, as
defined in Employer's Change of Control Severance Plan, Employee shall receive a
minimum of twenty-four (24) months of the then current Monthly Base Salary.
Employee shall not be under any duty or obligation to seek or accept other
employment following Involuntary Termination and the amounts due Employee
hereunder shall not be reduced or suspended if Employee accepts subsequent
employment. Employee's rights under this Section 3.5 are Employee's sole and
exclusive rights against Employer, Enron, or their affiliates, and Employer's
sole and exclusive liability to Employee under this Agreement, in contract,
tort, or otherwise, for any



                                       5
<PAGE>   6


Involuntary Termination of the employment relationship. Employee covenants not
to sue or lodge any claim, demand or cause of action against Employer for any
sums for Involuntary Termination other than those sums specified in this Section
3.5. If Employee breaches this covenant, Employer shall be entitled to recover
from Employee all sums expended by Employer (including costs and attorneys fees)
in connection with such suit, claim, demand or cause of action.

         3.6 Upon termination of the employment relationship as a result of
Employee's death, Employee's heirs, administrators, or legatees shall be
entitled to Employee's pro rata salary through the date of such termination, but
Employee's heirs, administrators, or legatees shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.7 Upon termination of the employment relationship as a result of
Employee's incapacity, Employee shall be entitled to his or her pro rata salary
through the date of such termination, but Employee shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.8 In all cases, the compensation and benefits payable to Employee
under this Agreement upon termination of the employment relationship shall be
offset against any amounts to which Employee may otherwise be entitled under any
and all severance plans, and policies of Employer, Enron, or their affiliates.

         3.9 Termination of the employment relationship does not terminate those
obligations imposed by this Agreement which are continuing obligations,
including, without limitation, Employee's obligations under Articles 6 and 7.

         3.10 Upon termination of the employment relationship between Employee
and Employer for any reason, Employee shall be entitled to receive compensation
and benefits earned and accrued by Employee during his/her employment as are
specifically provided in any applicable employee compensation and/or benefit
plan document and any grant or award agreement thereunder.

ARTICLE 4: CONTINUATION OF EMPLOYMENT BEYOND TERM; TERMINATION AND EFFECTS OF
           TERMINATION:

         4.1 Should Employee remain employed by Employer beyond the expiration
of the Term specified on Exhibit "A," such employment shall convert to a
month-to-month relationship terminable at any time by either Employer or
Employee for any reason whatsoever, with or without cause. Upon such termination
of the employment relationship by either Employer or Employee for any reason
whatsoever, all future compensation to which Employee is entitled and all future
benefits for which Employee is eligible shall cease and terminate. Employee
shall be entitled to pro rata salary through the date of such termination, but
Employee shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.


                                       6
<PAGE>   7

ARTICLE 5: UNITED STATES FOREIGN CORRUPT PRACTICES ACT AND OTHER LAWS:

         5.1. Employee shall at all times comply with United States laws
applicable to Employee's actions on behalf of Employer, including specifically,
without limitation, the United States Foreign Corrupt Practices Act, generally
codified in 15 USC 78 (FCPA), as the FCPA may hereafter be amended, and/or its
successor statutes. If Employee pleads guilty to or nolo contendere or admits
civil or criminal liability under the FCPA or other applicable United States
law, or if a court finds that Employee has personal civil or criminal liability
under the FCPA or other applicable United States law, or if a court finds that
Employee committed an action resulting in any Enron entity having civil or
criminal liability or responsibility under the FCPA or other applicable United
States law with knowledge of the activities giving rise to such liability or
knowledge of facts from which Employee should have reasonably inferred the
activities giving rise to liability had occurred or were likely to occur, such
action or finding shall constitute "cause" for termination under this Agreement
unless Employer's management committee (or, if there is no management committee,
the highest applicable level of Employer's management) determines that the
actions found to be in violation of the FCPA or other applicable United States
law were taken in good faith and in compliance with all applicable policies of
Employer and Enron.

ARTICLE 6: OWNERSHIP AND PROTECTION OF INFORMATION; COPYRIGHTS:

         6.1 All information, ideas, concepts, improvements, discoveries, and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by Employee, individually or in conjunction with others, during
Employee's employment by Employer (whether during business hours or otherwise
and whether on Employer's premises or otherwise) which relate to Employer's
business, products or services (including, without limitation, all such
information relating to corporate opportunities, research, financial and sales
data, pricing and trading terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the
identity of key contacts within the customer's organizations or within the
organization of acquisition prospects, or marketing and merchandising
techniques, prospective names, and marks) shall be disclosed to Employer and are
and shall be the sole and exclusive property of Employer. Moreover, all
drawings, memoranda, notes, records, files, correspondence, drawings, manuals,
models, specifications, computer programs, maps and all other writings or
materials of any type embodying any of such information, ideas, concepts,
improvements, discoveries, and inventions are and shall be the sole and
exclusive property of Employer.

         6.2 Employee acknowledges that the business of Employer, Enron, and
their affiliates is highly competitive and that their strategies, methods,
books, records, and documents, their technical information concerning their
products, equipment, services, and processes, procurement procedures and pricing
techniques, the names of and other information (such as credit and financial
data) concerning their customers and business affiliates, all comprise
confidential business information and trade secrets which are valuable, special,
and unique assets which Employer, Enron, or their affiliates use in their
business to obtain a competitive advantage over their competitors. Employee
further acknowledges that protection of such confidential business information
and trade secrets against unauthorized disclosure and use is of critical
importance to Employer, Enron, and their affiliates in maintaining their
competitive position. Employee hereby agrees that Employee will not, at any time
during or after his or her employment by Employer, make any unauthorized
disclosure of any confidential business information or trade secrets of
Employer, Enron, or their affiliates, or make any use thereof, except in the
carrying out of his or her employment responsibilities hereunder.







                                       7

Enron and its affiliates shall be third party beneficiaries of Employee's
obligations under this Section. As a result of Employee's employment by
Employer, Employee may also from time to time have access to, or knowledge of,
confidential business information or trade secrets of third parties, such as
customers, suppliers, partners, joint venturers, and the like, of Employer,
Enron, and their affiliates. Employee also agrees to preserve and protect the
confidentiality of such third party confidential information and trade secrets
to the same extent, and on the same basis, as Employer's confidential business
information and trade secrets. Employee acknowledges that money damages would
not be sufficient remedy for any breach of this Article 6 by Employee, and
Employer shall be entitled to enforce the provisions of this Article 6 by
terminating any payments then owing to Employee under this Agreement and/or to
specific performance and injunctive relief as remedies for such breach or any
threatened breach. Such remedies shall not be deemed the exclusive remedies for
a breach of this Article 6, but shall be in addition to all remedies available
at law or in equity to Employer, including the recovery of damages from Employee
and his or her agents involved in such breach.

         6.3 All written materials, records, and other documents made by, or
coming into the possession of, Employee during the period of Employee's
employment by Employer which contain or disclose confidential business
information or trade secrets of Employer, Enron, or their affiliates shall be
and remain the property of Employer, Enron, or their affiliates, as the case may
be. Upon termination of Employee's employment by Employer, for any reason,
Employee promptly shall deliver the same, and all copies thereof, to Employer.

         6.4 If, during Employee's employment by Employer, Employee creates any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures, or the like) relating to Employer's business,
products, or services, whether such work is created solely by Employee or
jointly with others (whether during business hours or otherwise and whether on
Employer's premises or otherwise), Employee shall disclose such work to
Employer. Employer shall be deemed the author of such work if the work is
prepared by Employee in the scope of his or her employment; or, if the work is
not prepared by Employee within the scope of his or her employment but is
specially ordered by Employer as a contribution to a collective work, as a part
of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation, or as an instructional text, then the work
shall be considered to be work made for hire and Employer shall be the author of
the work. If such work is neither prepared by the Employee within the scope of
his or her employment nor a work specially ordered and is deemed to be a work
made for hire, then Employee hereby agrees to assign, and by these presents does
assign, to Employer all of Employee's worldwide right, title, and interest in
and to such work and all rights of copyright therein.

         6.5 Both during the period of Employee's employment by Employer and
thereafter, Employee shall assist Employer and its nominee, at any time, in the
protection of Employer's worldwide right, title, and interest in and to
information, ideas, concepts, improvements, discoveries, and inventions, and its
copyrighted works, including without limitation, the execution of all formal
assignment documents requested by Employer or its nominee and the execution of
all lawful oaths and applications for applications for patents and registration
of copyright in the United States and foreign countries.

ARTICLE 7: POST-EMPLOYMENT NON-COMPETITION OBLIGATIONS:

         7.1 As part of the consideration for the compensation and benefits to
be paid to Employee hereunder, in keeping with Employee's duties as a fiduciary
and in order to protect Employer's interests in the confidential information of
Employer and the business relationships developed by Employee with the clients
and potential clients of Employer, and as an additional incentive for Employer
to enter into this Agreement, Employer and Employee agree to the non-competition
provisions of this Article 7. Employee agrees that during the period of
Employee's non-competition obligations hereunder, Employee will not, directly or
indirectly for Employee or for others, in any geographic area or market where
Employer or Enron or any of their affiliated companies are conducting any
business as of the date of termination of the employment relationship or have
during the previous twelve months conducted any business:

         (i) engage in any business competitive with the business conducted by
Employer;

         (ii) render advice or services to, or otherwise assist, any other
person, association, or entity who is engaged, directly or indirectly, in any
business competitive with the business conducted by Employer;

         (iii) induce any employee of Employer or Enron or any of their
affiliates to terminate his or her employment with Employer, Enron, or their
affiliates, or hire or assist in the hiring of any such employee by person,
association, or entity not affiliated with Enron.

These non-competition obligations shall extend until the earlier of (a)
expiration of the Term or (b) one year after termination of the employment
relationship. For purposes of this Section, it is specifically understood that
Employee may return to private legal practice, and may represent companies which
compete with Employer in such private legal practice, without breaching the
provisions of this Section.

         7.2 Employee understands that the foregoing restrictions may limit his
or her ability to engage in certain businesses anywhere in the world during the
period provided for above, but acknowledges that Employee will receive
sufficiently high remuneration and other benefits (e.g., the right to receive
compensation under Section 3.5 for the remainder of the Term upon Involuntary
Termination) under this Agreement to justify such restriction. Employee
acknowledges that money damages would not be sufficient remedy for any breach of
this Article 7 by Employee, and Employer shall be entitled to enforce the
provisions of this Article 7 by terminating any payments then owing to Employee
under this Agreement and/or to specific performance and injunctive relief as
remedies for such breach or any threatened breach. Such remedies shall not be
deemed the exclusive remedies for a breach of this Article 7, but shall be in
addition to all remedies available at law or in equity to Employer, including,
without limitation, the recovery of damages from Employee and his or her agents
involved in such breach.

         7.3 It is expressly understood and agreed that Employer and Employee
consider the restrictions contained in this Article 7 to be reasonable and
necessary to protect the proprietary information of Employer. Nevertheless, if
any of the aforesaid restrictions are found by a court having jurisdiction to be
unreasonable, or overly broad as to geographic area or time, or otherwise

unenforceable, the parties intend for the restrictions therein set forth to be
modified by such courts so as to be reasonable and enforceable and, as so
modified by the court, to be fully enforced.

representatives that are slanderous, libelous, or defamatory; or that disclose
private or confidential information about Employer, Enron, any of their
respective subsidiaries or affiliates, or any of such entities' business
affairs, officers, employees, agents, or representatives; or that constitute an

their respective subsidiaries or affiliates, or any of such entities' or its
officers, employees, agents, or representatives. A violation or threatened
violation of this prohibition may be enjoined by the courts. The rights afforded
the Enron entities and affiliates under this provision are in addition to any
and all rights and remedies otherwise afforded by law.

         8.4 This Agreement shall be governed in all respects by the laws of the

         8.5 No failure by either party hereto at any time to give notice of any

effected upon a party, each party hereby irrevocably appoints the Secretary of
State for the State of Texas as its or his agent for service of process to
receive the summons and other pleadings in connection with any such litigation.

         8.8 It is a desire and intent of the parties that the terms,
provisions, covenants, and remedies contained in this Agreement shall be
enforceable to the fullest extent permitted by law. If any such term, provision,
covenant, or remedy of this Agreement or the application thereof to any person,
association, or entity or circumstances shall, to any extent, be construed to be
invalid or unenforceable in whole or in part, then such term, provision,
covenant, or remedy shall be construed in a manner so as to permit its
enforceability under the applicable law to the fullest extent permitted by law.
In any case, the remaining provisions of this Agreement or the application
thereof to any person, association, or entity or circumstances other than those
to which they have been held invalid or unenforceable, shall remain in full
force and effect.

         8.10 There exist other agreements between Employer and Employee
relating to the employment relationship between them, e.g., the agreement with
respect to company policies contained in Employer's Conduct of Business Affairs
booklet and agreements with respect to compensation and benefit plans. This
Agreement replaces and merges previous agreements and discussions pertaining to
the following subject matters covered herein: the nature of Employee's
employment relationship with Employer and the term and termination of such
relationship. This Agreement constitutes the entire agreement of the parties
with regard to such subject matters, and contains all of the covenants,
promises, representations, warranties, and agreements between the parties with
respect such subject matters. Each party to this Agreement acknowledges that no
representation, inducement, promise, or agreement, oral or written, has been
made by either party with respect to such subject matters, which is not embodied
herein, and that no agreement, statement, or promise relating to the employment
of Employee by Employer that is not contained in this Agreement shall be valid
or binding. Any modification of this Agreement will be effective only if it is
in writing and signed by each party whose rights hereunder are affected thereby,
provided that any such modification must be authorized or approved by the Board
of Directors of Employer.

         IN WITNESS WHEREOF, Employer and Employee have duly executed this
Agreement in multiple originals to be effective on the date first stated above.
