         6.2      DEFINITION OF DISABILITY

         For purposes of Section 6.1, the Executive will be deemed to have a

perform the Executive's duties under this Agreement for 120 consecutive days, or
180 days during any twelve-month period, as determined in accordance with this
Section 6.2. The disability of the Executive will be determined by a medical
doctor selected by written agreement of the Employer and the Executive upon the
request of either party by notice to the other. If the Employer and the
Executive cannot agree on the selection of a medical doctor, each of them will
select a medical doctor and the two medical doctors will select a third medical
doctor who will determine whether the Executive has a disability. The
determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Executive must submit to a reasonable number of
examinations by the medical doctor making the determination of disability under
this Section 6.2, and the Executive hereby authorizes the disclosure and release
to the Employer of such determination and all supporting medical records. If the
Executive is not legally competent, the Executive's legal guardian or duly
authorized attorney-in-fact will act in the Executive's stead, under this
Section 6.2, for the purposes of submitting the Executive to the examinations,
and providing the authorization of disclosure, required under this Section 6.2.

         6.3      DEFINITION OF "FOR CAUSE"

         For purposes of Section 6.1, the phrase "for cause" means: (a) the
Executive's breach of this Agreement; (b) the Executive's failure to adhere to
any written Employer policy if the Executive has been given a reasonable
opportunity to comply with such policy or cure his failure to comply (which
reasonable opportunity must be granted during the ten-day period preceding
termination of this Agreement); (c) the appropriation (or attempted
appropriation) of a material business opportunity of the Employer, including
attempting to secure or securing any personal profit in connection with any
transaction entered into on behalf of the Employer; (d) the misappropriation (or
attempted misappropriation) of any of the Employer's funds or property; or (e)
the conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, the equivalent thereof, or any other crime with respect to
which imprisonment is a possible punishment.

         6.4      DEFINITION OF "GOOD REASON"

         For purposes of Section 6.1, the phrase "for good reason" means any of
the following: (a) The Employer's breach of this Agreement; (b) the assignment
of the Executive without his consent to a position, responsibilities, or duties
of a materially lesser status or degree of responsibility than his position,
responsibilities, or duties at the Effective Date.

         6.5      TERMINATION PAY

         Effective upon the termination of this Agreement, the Employer will be

Section 6.5, and in lieu of all other amounts and in settlement and complete


                                       5

of this Section 6.5, the Executive's designated beneficiary will be such
individual beneficiary or trust, located at such address, as the Executive may
designate by notice to the Employer from time to time or, if the Executive fails
to give notice to the Employer of such a beneficiary, the Executive's estate.
Notwithstanding the preceding sentence, the Employer will have no duty, in any
circumstances, to attempt to open an estate on behalf of the Executive, to
determine whether any beneficiary designated by the Executive is alive or to
ascertain the address of any such beneficiary, to determine the existence of any
trust, to determine whether any person or entity purporting to act as the
Executive's personal representative (or the trustee of a trust established by
the Executive) is duly authorized to act in that capacity, or to locate or
attempt to locate any beneficiary, personal representative, or trustee.

         (a) TERMINATION BY THE EXECUTIVE FOR GOOD REASON. If the Executive
terminates this Agreement for good reason, the Employer will pay the Executive
(i) the Executive's Salary in effect for the remainder, if any, of the calendar
month in which such termination is effective and for six consecutive calendar
months thereafter, (ii) that portion of the Executive's Incentive Compensation,
if any, for the Fiscal Year during which the termination is effective, prorated
through the date of termination, and (iii) medical coverage for Executive at no
expense to Executive for six months following termination.

         (b) TERMINATION BY THE EMPLOYER FOR CAUSE. If the Employer terminates

         (e) TERMINATION WITHOUT CAUSE. If this Agreement is terminated by
Employer without cause, the Executive will be entitled to receive his Salary for
six consecutive calendar months thereafter and that portion of Executive
Incentive Compensation, if any, for the Fiscal Year during which the termination
is effective, prorated through the date of termination, payment of accrued but
unused vacation and medical coverage for six months following termination. If
the Executive terminates this Agreement, without cause, Executive will be
entitled to his Salary only through the date such termination is effective and

Agreement without cause, Employer may request in writing that Executive delay
the effectiveness of such termination for up to sixty days during which
Executive will be entitled to his Salary through the date such termination is

         (f) TERMINATION BY EXECUTIVE OR CHANGE OF CONTROL. If the Executive
upon the consummation of a Change of Control of the Employer does not accept
employment with the Employer's successor following such Change of Control, then
Executive may terminate this Agreement and will be entitled to receive his
Salary for twenty four consecutive calendar months in accordance with normal
payroll practices of Employer, and that portion of the Executive Incentive
Compensation for the Fiscal Year during which such Change in Control occurred.
Executive will not be entitled to any compensation hereunder if Executive
terminates this Agreement pursuant to Section 6.1(f) and Executive is employed
in any capacity (except as a consultant for not more than 90 days) by the person
or entity which caused the Change of Control within a period of six months
following notice of termination by Executive pursuant to Section 6.1(f) hereof.
In the event that Executive terminates this Agreement pursuant to Section 6.1(f)
hereof, and receives any payments under this Section 6.5(f) and is also employed
by the Employer or the person or entity causing the Change of Control (i) within
six months of such termination, then Executive will immediately remit to
Employer all payments made by Employer to Executive pursuant to this Section
6.5(f) since the date of employment or, (ii) more than six months following such
termination, then Executive will no longer be entitled to any payments pursuant
to this Section 6.5(f). In addition, in the event that Executive terminates this
Agreement pursuant to this Section 6.5(f), Executive shall be provided medical
coverage for one year following termination.

         (g) BENEFITS. The Executive's accrual of, or participation in plans
providing for, the Benefits will cease at the effective date of the termination
of this Agreement, and the Executive will be entitled to accrued Benefits
pursuant to such plans only as provided in such plans. The Executive will not
receive, as part of his termination pay pursuant to this Section 6, any payment
or other compensation for any vacation, holiday, sick leave, or other leave
unused on the date the notice of termination is given under this Agreement
unless the Management Committee agrees in its sole discretion to such payment or
other compensation. Any payment of Incentive Compensation under this Section 6.5
shall be made as described in Section 3.2 hereof.

7.       NON-DISCLOSURE COVENANT

         7.1      ACKNOWLEDGMENTS BY THE EXECUTIVE

         The Executive acknowledges that (a) during the Employment Period and as
a part of his employment, the Executive will be afforded access to Confidential
Information; (b) public disclosure of such Confidential Information could have
an adverse effect on the Employer and its business; and (c) the provisions of
this Section 7 are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information.

         7.2      COVENANTS OF THE EXECUTIVE

         In consideration of the compensation and benefits to be paid or
provided to the Executive by the Employer under this Agreement, the Executive
covenants as follows:

         (a)      CONFIDENTIALITY.

                           (1) During and following the Employment Period, for a
                  period of three years, the Executive will hold in confidence
                  the Confidential Information and will not disclose it to any
                  person except with the specific prior written consent of the
                  Employer or except as otherwise expressly permitted by the
                  terms of this Agreement.

                           (2) Any trade secrets of the Employer will be
                  entitled to all of the protections and benefits under the laws
                  of the State of Texas and any other applicable law. If any
                  information that the Employer deems to be a trade secret is
                  found by a court of competent jurisdiction not to be a trade


                                       7
<PAGE>

                  secret for purposes of this Agreement, such information will,
                  nevertheless, be considered Confidential Information for
                  purposes of this Agreement. The Executive hereby waives any
                  requirement that the Employer submits proof of the economic
                  value of any trade secret or post a bond or other security.

                           (3) None of the foregoing obligations and
                  restrictions applies to any part of the Confidential
                  Information that the Executive demonstrates was or became
                  generally available to the public other than as a result of a
                  disclosure by the Executive.

                           (4) The Executive will not remove from the Employer's
                  premises (except to the extent such removal is for purposes of
                  the performance of the Executive's duties at home or while
                  traveling, or except as otherwise specifically authorized by
                  the Employer) any document, record, notebook, plan, model,
                  component, device, or computer software or code, whether
                  embodied in a disk or in any other form (collectively, the
                  "Proprietary Items"). The Executive recognizes that, as
                  between the Employer and the Executive, all of the Proprietary
                  Items, whether or not developed by the Executive, are the
                  exclusive property of the Employer. Upon termination of this
                  Agreement by either party, or upon the request of the Employer
                  during the Employment Period, the Executive will return to the
                  Employer all of the Proprietary Items in the Executive's
                  possession or subject to the Executive's control, and the
                  Executive shall not retain any copies, abstracts, sketches, or
                  other physical embodiment of any of the Proprietary Items.

         7.3      DISPUTES OR CONTROVERSIES

         The Executive recognizes that should a dispute or controversy arising
from or relating to this Agreement be submitted for adjudication to any court,
arbitration panel, or other third party, the preservation of the secrecy of
Confidential Information may be jeopardized. All pleadings, documents,
testimony, and records relating to any such adjudication will be maintained in
secrecy and will be available for inspection by the Employer, the Executive, and
their respective attorneys and experts, who will agree, in advance and in
writing, to receive and maintain all such information in secrecy, except as may
be limited by them in writing.

intellectual character; (b) the Employer's business is worldwide in scope and
its products are marketed throughout the world; (c) the Employer competes with
other businesses that are or could be located in any part of the world; and (d)
the provisions of this Section 8 are reasonable and necessary to protect the
Employer's business.

         8.2      COVENANTS OF THE EXECUTIVE

         In consideration of the acknowledgments by the Executive, and in
consideration of the compensation and benefits to be paid or provided to the
Executive by the Employer, the Executive covenants that he will not, directly or
indirectly:

                  (a) during the Employment Period, except in the course of his
employment hereunder, and during the Post-Employment Period, engage or invest
in, own, manage, operate, finance, control, or participate in the ownership,
management, operation, financing, or control of, be employed by, associated
with, or in any manner connected with, lend the Executive's name or any similar
name to, lend Executive's credit to or render services or advice to, any
business who competes in the compressed air services anywhere within the world;


                                       8
<PAGE>

provided, however, that the Executive may purchase or otherwise acquire up to
(but not more than) one percent of any class of securities of any enterprise
(but without otherwise participating in the activities of such enterprise) if
such securities are listed on any national or regional securities exchange or
have been registered under Section 12(g) of the Securities Exchange Act of 1934;

                  (b) whether for the Executive's own account or for the account
of any other person, at any time during the Employment Period and the
Post-Employment Period, solicit business of the same or similar type being
carried on by the Employer, from any person known by the Executive to be a
customer of the Employer, whether or not the Executive had personal contact with
such person during and by reason of the Executive's employment with the
Employer;

                  (c) whether for the Executive's own account or the account of
any other person (i) at any time during the Employment Period and the
Post-Employment Period without the Employer's prior written consent, solicit,
employ, or otherwise engage as an employee, independent contractor, or
otherwise, any person who is or was an employee of the Employer at any time
during the Employment Period or in any manner induce or attempt to induce any
employee of the Employer to terminate his employment with the Employer; or (ii)
at any time during the Employment Period and for three years thereafter,
interfere with the Employer's relationship with any person, including any person
who at any time during the Employment Period was an employee, contractor,
supplier, or customer of the Employer; or

                  (d) at any time during or after the Employment Period,
disparage the Employer or any of its shareholders, directors, officers,
employees, or agents.

For purposes of this Section 8.2, the term "Post-Employment Period" means the
three year period beginning on the date of termination of the Executive's
employment with the Employer.

         If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

         The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.

         The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. The Employer may notify
such employer that the Executive is bound by this Agreement and, at the
Employer's election, furnish such employer with a copy of this Agreement or
relevant portions thereof.

9.       GENERAL PROVISIONS

         9.1      INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

         The Executive acknowledges that the injury that would be suffered by
the Employer as a result of a breach of the provisions of this Agreement (as a
result of the provisions of Sections 7 and 8) would be irreparable and that an
award of monetary damages to the Employer for such a breach would be an
inadequate remedy. Consequently, the Employer will have the right, in addition
to any other rights it may have, to obtain injunctive relief to restrain any


                                       9
<PAGE>

breach or threatened breach or otherwise to specifically enforce any provision
of this Agreement, and the Employer will not be obligated to post bond or other
security in seeking such relief. Without limiting the Employer's rights under
this Section 9 or any other remedies of the Employer, if the Executive breaches
any of the provisions of Section 7 or 8, the Employer will have the right to
cease making any payments otherwise due to the Executive under this Agreement.

         9.2      COVENANTS OF SECTIONS 7 AND 8 ARE ESSENTIAL AND INDEPENDENT
                  COVENANTS

         The covenants by the Executive in Sections 7 and 8 are essential
elements of this Agreement, and without the Executive's agreement to comply with
such covenants, the Employer would not have entered into this Agreement. The
Employer and the Executive have independently consulted their respective counsel
and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Employer.

         The Executive's covenants in Sections 7 and 8 are independent covenants
and the existence of any claim by the Executive against the Employer under this
Agreement or otherwise, will not excuse the Executive's breach of any covenant
in Section 7 or 8.

         If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Sections 6.5, 7 and
8.

         9.3      REPRESENTATIONS AND WARRANTIES BY THE EXECUTIVE

         The Executive represents and warrants to the Employer that the
execution and delivery by the Executive of this Agreement do not, and the
performance by the Executive of the Executive's obligations hereunder will not,
with or without the giving of notice or the passage of time, or both: (a)
violate any judgment, writ, injunction, or order of any court, arbitrator, or
governmental agency applicable to the Executive; or (b) conflict with, result in
the breach of any provisions of or the termination of, or constitute a default
under, any agreement to which the Executive is a party or by which the Executive
is or may be bound.

         9.4      OBLIGATIONS CONTINGENT ON PERFORMANCE

         The obligations of the Employer hereunder, including its obligation to
pay the compensation provided for herein, are contingent upon the Executive's
performance of the Executive's obligations hereunder.

         9.5      WAIVER

         The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither the failure nor any delay by either party in
exercising any right, power, or privilege under this Agreement will operate as a
waiver of such right, power, or privilege, and no single or partial exercise of
any such right, power, or privilege will preclude any other or further exercise
of such right, power, or privilege or the exercise of any other right, power, or
privilege. To the maximum extent permitted by applicable law, (a) no claim or
right arising out of this Agreement can be discharged by one party, in whole or
in part, by a waiver or renunciation of the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any obligation
of such party or of the right of the party giving such notice or demand to take
further action without notice or demand as provided in this Agreement.

         9.6      BINDING EFFECT; DELEGATION OF DUTIES PROHIBITED

         This Agreement shall inure to the benefit of, and shall be binding
upon, the parties hereto and their respective successors, assigns, heirs, and
legal representatives, including any entity with which the Employer may merge or
consolidate or to which all or substantially all of its assets may be
transferred. The duties and covenants of the Executive under this Agreement,
being personal, may not be delegated.

         9.7      NOTICES

         All notices, consents, waivers, and other communications under this
Agreement must be in writing and will be deemed to have been duly given when (a)
delivered by hand (with written confirmation of receipt), (b) sent by facsimile

addressee, if sent by a nation-ally recognized overnight delivery service
