Employment Term for Cause (as defined herein), then Executive shall be entitled to receive only (i)
his Base Salary through the date of termination and (ii) such stock options, restricted stock
awards, and grants as shall have fully vested before the date of termination. In any such event,
Executive shall be ineligible for and shall forfeit all rights with respect to options and grants
that have not vested as of the time of termination for Cause.

2.5 Termination as a Result of Death. If Executive dies during the Employment Term, the

disability benefits shall be deemed conclusive evidence of Total Disability for purposes of this
Agreement. However, in the absence of Executive’s receipt of such long-term disability benefits or
Social Security benefits, the Chief Executive Officer in good faith may determine that the
Executive is disabled due to the needs of the business and the unacceptable unavailability of
Executive which is expected to last for a continuous period of not less than six (6) months. In

or until benefits become payable to the Executive under the terms of the Company’s disability
policy, whichever first occurs.

2.7 No Setoff. The Company’s obligation to make payments provided for in this Agreement and
otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right, or action which Company may have against the Executive
or others. In no event shall the Executive be obligated to seek other employment or take any other
action by way of mitigation of the amounts payable, or benefits to be provided to the Executive
under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not
the Executive obtains or seeks to obtain other employment.

2.8. Coordination of Benefits. In the event that the Employee is entitled to benefits
following Termination under any Change in Control Agreement with Newpark, the Employee shall have
the right to elect whether to receive such benefits under any such Change in Control Agreement or
this Employment Agreement, but not both.

representative, and those independent representatives shall choose the single arbitrator within
thirty (30) days of the date of the selection of the first independent representative. The legal
expenses of each party shall be borne by them respectively. However, the cost and expenses of the
arbitrator in any such action shall be borne equally by the parties. The arbitrator’s decision,

provisions of this Agreement.

(b) Company Property. All written materials, customer or other lists or data bases,
records, data, and other documents prepared or possessed by Executive during Executive’s employment
with the Company are the Company’s property. All information, ideas, concepts, improvements,
discoveries, and inventions that are conceived, made, developed, or acquired by Executive
individually or in conjunction with others during Executive’s employment (whether during business
hours and whether on the Company’s premises or otherwise) which relate to the Company’s business,
products, or services are the Company’s sole and exclusive property. All memoranda, notes,
records, files, correspondence, drawings, manuals, models, specifications, computer programs, maps,
and all other documents, data, or materials of any type embodying such information, ideas,
concepts, recipes, inventory, prices, improvements, discoveries, and inventions are the Company’s
property. At the termination of Executive’s employment with the Company for any reason, Executive
shall return all of the Company’s documents, data, or other Company Property to the Company.
Included in the above are all such data that Executive had access to, over, or possessed. The
Company desires by this Agreement to protect its economic investment in its current and future

(c) Confidential Information; Non-Disclosure. Executive acknowledges and stipulates
that the business of the Company is highly competitive, cost and price sensitive, and that he in
connection with his work and job have had access to Confidential Information relating to the
Company’s businesses and their methods and operations. For purposes of this Agreement, “
Confidential Information ” means and includes the Company’s confidential and/or proprietary
information and/or trade secrets that have been developed or used and/or will be developed and that
cannot be obtained readily by third parties from outside sources. Confidential Information
includes, by way of example and without limitation, the following information regarding customers,
employees, contractors, its operations and its markets and the industry not generally known to the
public; strategies, methods, books, records, and documents; recipes, technical information
concerning products, equipment, services, and processes; procurement procedures and pricing
techniques; the names of and other information concerning customers and those being solicited to be

relating to the Company’s relationship with that customer); pricing strategies and price curves;
positions, plans, and strategies for expansion or acquisitions; budgets; customer lists; research;
financial and sales data; raw materials purchasing or trading methodologies and terms; evaluations,
opinions, and interpretations of information and data; marketing and merchandising techniques;

the Company; bids or proposals submitted to any third party; technologies and methods; training
methods and training processes; organizational structure; personnel information, including salaries
of personnel; labor or employee relations or agreements; payment amounts or rates paid to
consultants or other service providers; and other such confidential or proprietary information.
Information need not qualify as a trade secret to be protected as Confidential Information under
this Agreement, and the authorized and controlled disclosure of Confidential Information to
authorized parties by Company in the pursuit of its business will not cause the information to lose
its protected status under this Agreement. Executive acknowledges and stipulates that this
Confidential Information constitutes a valuable, special, and unique asset used by the Company in
its businesses to obtain a competitive advantage over its competitors. Executive further
acknowledges that protection of such Confidential Information against unauthorized disclosure and
use is of critical importance to the Company in maintaining its competitive position and economic
investment, as well as work for its employees.

(d) Unfair Competition Restrictions. Executive agrees that for a period of twenty-
four (24) months following the date of his termination (“ Restricted Term ”), he will not,
directly or indirectly, for himself or for others, anywhere in those areas where the Company
currently (including the City of New Orleans and its surrounding parishes, and in those cities or
parishes listed in Attachment “A-1” attached hereto) (the “ Restricted Area ”) conducts or
is seeking to conduct business of the same nature as the Company, including the Related Entities,
do any of the following, unless expressly authorized by the Chief Executive Officer of the Company:
Engage in, or assist any person, entity, or business engaged in, the selling or providing of
products or services that would displace the products or services that (i) the Company is currently
in the business of providing and was in the business of providing, or is planning to be in the
business of providing, at the time of the execution of this Agreement, or (ii) that Executive had involvement in, access to, or received Confidential Information about in the course of employment.
The foregoing is expressly understood to include, without limitation, the business of the
manufacturing, selling and/or providing products or services of the same type offered and/or sold
by the Company..

4. Prohibition on Circumvention. It is further agreed that during the Restricted
Term, Executive cannot circumvent these covenants by alternative means or engage in any of the
enumerated prohibited activities in the Restricted Area by means of telephone, telecommunications,
satellite communications, correspondence, or other contact from outside the Restricted Area.
Executive further understands that the foregoing restrictions may limit his ability to engage in
certain businesses during the Restricted Term, but acknowledge that these restrictions are
necessary to protect the Confidential Information and business interests of the Company.

5. Proviso. It is agreed that these covenants do not prevent Executive from using
and offering the general management or other skills that he possessed prior to receiving access to
Confidential Information and knowledge from the Company. This Agreement creates an advance
approval process, and nothing herein is intended, or will be construed as, a general restriction
against Executive’s pursuit of lawful employment in violation of any controlling state or federal
laws. Executive is permitted to engage in activities that would otherwise be prohibited by this
covenant if such activities are determined in the sole discretion of the Chief Executive Officer of
the Company, and authorized in writing, to be of no material threat to the legitimate business
interests of the Company.

6. Non-Solicitation of Customers. For a period of twenty-four (24) months following
Executive’s termination of employment or employment agreement, Executive agrees not to call on,
service, or solicit competing business from customers of the Company, in the Restricted Area, whom
he, within the previous twenty-four (24) months, (i) had or made contact with, or (ii) induce or
encourage any such customer or other source of ongoing business to stop doing business with the
Company. This provision does not prohibit Executive from managing or providing other services or
products that are not a product or services currently offered by the Company.

7. Non-Solicitation of Employees. For a period of twenty-four (24) months following
the date of Executive’s termination of employment or employment agreement, Executive will not,
either directly or indirectly, call on, solicit, encourage, or induce any other employee or officer
of the Company, whom he had contact with, knowledge of, or association within the course of
employment with the Company to discontinue his or her employment, and will not assist any other
person or entity in such a solicitation.

8. Non-Disparagement. Executive covenants and agrees he will not engage in any
pattern of conduct that involves the making or publishing of written or oral statements or remarks
(including, without limitation, the repetition or distribution of derogatory rumors, allegations,
negative reports or comments) which are disparaging, deleterious or damaging to the integrity,
reputation or good will of the Company or its respective management or products and services.

9. Separability of Covenants. The covenants contained in Section 3 herein
constitute a series of separate but ancillary covenants, one for each applicable parish in the
State of Louisiana set forth in this Agreement or Attachment “A-1” hereto. If in any judicial
proceeding, a court shall hold that any of the covenants set forth in Section 3 exceed the time,
geographic, or occupational limitations permitted by applicable law, Executive and the Company
agree that such provisions shall and are hereby reformed to the maximum time, geographic, or
occupational limitations permitted by such laws, Further, in the event a court shall hold
unenforceable any of the separate covenants deemed included herein, then such unenforceable
covenant or covenants shall be deemed eliminated from the provisions of this Agreement for the
purpose of such proceeding to the extent necessary to permit the remaining separate covenants to be
enforced in such proceeding. Executive and the Company further agree that the covenants in Section
3 shall each be construed as a separate agreement independent of any other provisions of this
Agreement, and the existence of any claim or cause of action by Executive against the Company,
whether predicated on this Agreement, his Employment Agreement or otherwise, shall not constitute a defense to the enforcement
by the Company of any of the covenants of Section 3.

except as may be specifically provided for to the contrary in the Employment Agreement.

14. Entire Agreement. Except with respect to the Employment Agreement executed
concurrently herewith, and with respect to certain matters included in a separate Agreement being
entered into between Executive and the Company on the date of this Agreement (“ Appendix B and B-1
”), this Agreement constitutes the entire agreement between the parties hereto with respect to the
subject matter of this Agreement and supersedes and is in full substitution for any and all prior
agreements and understandings whether written or oral between said parties relating to the subject
matter of this Agreement. This Agreement shall not supersede or substitute for, nor be superseded
or substituted by, the Employment Agreement, but shall have full force and effect concurrently
therewith.

15. Amendment. This Agreement may not be amended or modified in any respect except
by an agreement in writing executed by the parties in the same manner as this Agreement except as
provided in Section 18 of this Agreement.

16. Assignment. This Agreement (including, without limitation, Executive’s
obligations under Sections 3 and 4) may not be assigned by the Company in a manner inconsistent
with 3.8 of Executive’s Employment Agreement without the consent of Executive in connection with
the sale, transfer or other assignment of all or substantially all of the capital stock or assets

or into which the company merges assumes in writing the obligations of the Company hereunder and

part, term and/or provision of this Agreement would otherwise be found null, void, or unenforceable
under applicable law by any court of competent jurisdiction, that section, paragraph, part, term
and/or provision shall automatically not constitute part of this Agreement. Each section,
paragraph, part, term and/or provision of this Agreement is intended to be and is severable from
the remainder of this Agreement. If, for any reason, any section, paragraph, part, term and/or
provision herein is determined not to constitute part of this Agreement or to be null, void, or
unenforceable under applicable law by any court of competent jurisdiction, the operation of the

addition, and not in lieu of, any other remedies to which the Company may show themselves justly
entitled, including, but not limited to, specific performance and damages. The parties

to cease any payments under the Employment Agreement and recover all payments made to Executive
under the Employment Agreement on or subsequent to the date of the failure, (ii) obtain an injunction

products or services that would displace the products or services that (i) the Company is currently
in the business of providing and was in the business of providing, or is planning to be in the business of providing, at the time of the execution of this Agreement, or (ii) that
Executive had involvement in, access to, or received Confidential Information about in the course
of employment. The foregoing is expressly understood to include, without limitation, the business
of the manufacturing, selling and/or providing products or services of the same type offered and/or
sold by the Company.

4. Prohibition on Circumvention. It is further agreed that during the Restricted
Term, Executive cannot circumvent these covenants by alternative means or engage in any of the
enumerated prohibited activities in the Restricted Area by means of telephone, telecommunications,
satellite communications, correspondence, or other contact from outside the Restricted Area.
Executive further understands that the foregoing restrictions may limit his ability to engage in
certain businesses during the Restricted Term, but acknowledge that these restrictions are
necessary to protect the Confidential Information and business interests of the Company.

5. Proviso. It is agreed that these covenants do not prevent Executive from using
and offering the general management or other skills that he possessed prior to receiving access to
Confidential Information and knowledge from the Company. This Agreement creates an advance
approval process, and nothing herein is intended, or will be construed as, a general restriction
against Executive’s pursuit of lawful employment in violation of any controlling state or federal
laws. Executive is permitted to engage in activities that would otherwise be prohibited by this
covenant if such activities are determined in the sole discretion of the Board of the Company, and
authorized in writing, to be of no material threat to the legitimate business interests of the
Company.

6. Non-Solicitation of Customers. For a period of twenty-four (24) months following
Executive’s termination of employment or employment agreement, Executive agrees not to call on,
service, or solicit competing business from customers of the Company, in the Restricted Area, whom
he, within the previous twenty-four (24) months, (i) had or made contact with, or (ii) induce or
encourage any such customer or other source of ongoing business to stop doing business with the
Company. This provision does not prohibit Executive from managing or providing other services or
products that are not a product or services currently offered by the Company.

7. Non-Solicitation of Employees. For a period of twenty-four (24) months following
the date of Executive’s termination of employment or employment agreement, Executive will not,
either directly or indirectly, call on, solicit, encourage, or induce any other employee or officer
of the Company, whom he had contact with, knowledge of, or association within the course of
employment with the Company to discontinue his or her employment, and will not assist any other
person or entity in such a solicitation.

8. Non-Disparagement. Executive covenants and agrees he will not engage in any
pattern of conduct that involves the making or publishing of written or oral statements or remarks
(including, without limitation, the repetition or distribution of derogatory rumors, allegations,
negative reports or comments) which are disparaging, deleterious or damaging to the integrity,
reputation or good will of the Company or its respective management or products and services.

9. Separability of Covenants. The covenants contained in Section 3 herein
constitute a series of separate but ancillary covenants, one for each applicable county in the
State of Texas and/or each area of operation in each state, county, and area as set forth in this
Agreement or Attachment “B- 1” hereto. If in any judicial proceeding, a court shall hold that any
of the covenants set forth in Section 3 exceed the time, geographic, or occupational limitations
permitted by applicable law, Executive and the Company agree that such provisions shall and are
hereby reformed to the maximum time, geographic, or occupational limitations permitted by such
laws. Further, in the event a court shall hold unenforceable any of the separate covenants deemed
included herein, then such unenforceable covenant or covenants shall be deemed eliminated from the
provisions of this Agreement for the purpose of such proceeding to the extent necessary to permit
the remaining separate covenants to be enforced in such proceeding. Executive and the Company
further agree that the covenants in Section 3 shall each be construed as a separate agreement
independent of any other provisions of this Agreement, and the existence of any claim or cause of
action by Executive against the Company, whether predicated on this Agreement or Employment Agreement or
otherwise, shall not constitute a defense to the enforcement by the Company of any of the covenants
of Section 3.

10. Consideration. Executive acknowledges and agrees that no other consideration for
Executive’s covenants in this Agreement, other than that specifically referred to in Section 1 of
the Employment Agreement, has or will be paid or furnished to him by the Company or the Related
Entities.

11. Return of Items. Upon termination and/or retirement, Executive will return any
computer related hardware or software, cell phone, keys, or other data or company property in his
possession or control, including all customer list(s), pricing documents, etc., to the Company,
except as may be specifically provided for to the contrary in Executive’s Employment Agreement.

or other entity to leave the employ of the Company or any affiliated corporation or other entity to
accept employment with Executive or with such person, firm, association, corporation, or other
entity.

environmental services to the exploration, production and maritime industries, mat sales and
rentals, drilling fluids, and water treatment and related technology; and, heavy oil and air
treatment.

(c) The phrase “ carries on a like business ” includes, without limitation,
actions taken by or through a wholly-owned subsidiary or other affiliated corporation or entity.

(d) All references to the Company shall also be deemed to refer to and include the
Related Entities

13. Reasonable Restrictions. Executive represents to the Company that the
enforcement of the restrictions contained in this Agreement would not be unduly burdensome to
Executive and acknowledges that Executive is willing and able, subject to the Restricted Area as
defined herein, to compete in other geographical areas not prohibited by this Agreement. The parties to this
Agreement hereby agree that the covenants contained in this Agreement are reasonable.

14. Entire Agreement. Except with respect to the Employment Agreement executed
concurrently herewith, and with respect to certain matters included in a separate Agreement being
entered into between Executive and the Company on the date of this Agreement (“ Appendix A and A-1
”), this Agreement constitutes the entire agreement between the parties hereto with respect to the
subject matter of this Agreement and supersedes and is in full substitution for any and all prior
agreements and understandings whether written or oral between said parties relating to the subject
matter of this Agreement. This Agreement shall not supersede or substitute for, nor be superseded
or substituted by, the Employment Agreement, but shall have full force and effect concurrently
therewith.

15. Amendment. This Agreement may not be amended or modified in any respect except
by an agreement in writing executed by the parties in the same manner as this Agreement except as
provided in Section 18 of this Agreement.

16. Assignment. This Agreement (including, without limitation, Executive’s
obligations under Sections 3 and 4) may not be assigned by the Company in a manner inconsistent
with 3.8 of Executive’s Employment Agreement without the consent of Executive in connection with
the sale, transfer or other assignment of all or substantially all of the capital stock or assets
of, or the merger of, the Company provided that the party acquiring such capital stock or assets or
into which the company merges assumes in writing the obligations of the Company hereunder and
provided further that no such assignment shall release the Company from its obligations hereunder.
This Agreement (including, without limitation, Executive’s obligations under Sections 3 and 4) may
not be assigned or encumbered in any way by Executive without the written consent of the Company.

17. Successors. This Agreement (including, without limitation, Executive’s
obligations under Sections 3 and 4) shall be binding upon and shall inure to the benefit of and be
enforceable by each of the parties and their respective successors and assigns.

18. Unenforceable Provisions. If, and to the extent that, any section, paragraph,
part, term and/or provision of this Agreement would otherwise be found null, void, or unenforceable
under applicable law by any court of competent jurisdiction, that section, paragraph, part, term
and/or provision shall automatically not constitute part of this Agreement. Each section,
paragraph, part, term and/or provision of this Agreement is intended to be and is severable from
the remainder of this Agreement. If, for any reason, any section, paragraph, part, term and/or
provision herein is determined not to constitute part of this Agreement or to be null, void, or
unenforceable under applicable law by any court of competent jurisdiction, the operation of the
other sections, paragraphs, parts, terms and/or provisions of this Agreement as may remain
otherwise intelligible shall not be impaired or otherwise affected and shall continue to have full
force and effect and bind the parties hereto.

19. Remedies.

(a) Executive agrees that a breach or violation of Section 3 or 4 of this Agreement
by Executive shall entitle the Company as a matter of right, to an injunction, without necessity of
posting bond, issued by any court of competent jurisdiction, restraining any further or continued
breach or violation of such provisions. Such right to an injunction shall be cumulative and in
addition, and not in lieu of, any other remedies to which the Company may show themselves justly
entitled, including, but not limited to, specific performance and damages. The parties
specifically agree that the remedy of damages alone is inadequate.

(b) In the event that Executive knowingly and intentionally fails in any material
respect to perform any of his material obligations under this Agreement, the Company may elect (i)
to cease any payments due under the Employment Agreement and recover all payments made to Executive under the Employment Agreement on or subsequent to the date of the failure, (ii) obtain an
injunction and/or (iii) exercise any and all other remedies available by law.

Notwithstanding the foregoing subsection (b), Executive will have no liability or responsibility
for: (i) inadvertent disclosure or use of the Information if (x) he uses the same degree of care in
safeguarding the Information that the Company uses to safeguard information of like importance and
(y) upon discovery of such inadvertent disclosure or use of such material, Executive immediately
uses his best efforts, including the commencement of litigation, if necessary, to prevent any use
thereof by the person or persons to whom it has been disclosed and to prevent any further
incidental disclosure thereof; and (ii) , disclosure of Information (x) that is required by law,
(y) that is made pursuant to a proper subpoena from a court or administrative agency of competent
jurisdiction from a court or administrative agency of competent jurisdiction or (z) that is made

Executive immediately notifies the Company of the requested disclosure by the most immediate means
of communication available and confirms in writing such notification within one business day
