         other event has occurred or any other circumstances exist, that would
         lead a prudent Person to conclude that such a claim, Proceeding,
         dispute, action, or other matter is likely to be asserted, commenced,
         taken, or otherwise pursued in the future.

financial statements, to normal recurring year-end adjustments (the effect of
which will not, individually or in the aggregate, be materially adverse) and the
absence of notes (that, if presented, would not differ materially from those
included in the Balance Sheet); the financial statements referred to in this
Section 3.4 reflect the consistent application of such accounting principles
throughout the periods involved. No financial statements of any Person other

practices, including the maintenance of an adequate system of internal controls.
The minute books of the Company contain accurate and complete records of all
meetings held of, and action taken by, the members or the managers, and no
meeting of any such members, managers, or committee has been held for which
minutes have not been prepared and are not contained in such minute books. At
the Closing, all of those books and records will be in the possession of the
Company.

         3.6      TITLE TO PROPERTIES; ENCUMBRANCES

The Company owns all the properties and assets (whether real, personal, or mixed
and whether tangible or intangible) that they purport to own located in the
facilities operated by the Company or reflected as owned in the books and
records of the Company, including all of the properties and assets reflected in
the Balance Sheet and the Interim Balance Sheet (except for assets held under

and the Interim Balance Sheet, as the case may be, in the Ordinary Course of
Business), and all of the properties and assets purchased or otherwise acquired
by the Company since the date of the Balance Sheet (except for personal property
acquired and sold since the date of the Balance Sheet in the Ordinary Course of
Business and consistent with past practice). All material properties and assets
reflected in the Balance Sheet and the Interim Balance Sheet are free and clear
of all Encumbrances except (a) security interests shown on the Balance Sheet or
the Interim Balance Sheet as securing specified liabilities or obligations, with
respect to which no default (or event that, with notice or lapse of time or

connection with the purchase of property or assets after the date of the Interim
Balance Sheet (such security interests being limited to the property or assets
so acquired), with respect to which no default (or event that, with notice or

         The buildings, plants, structures, and equipment of the Company are
structurally sound, are in good operating condition and repair, and are adequate
for the uses to which they are being put, and none of such buildings, plants,
structures, or equipment is in need of maintenance or repairs except for
ordinary, routine maintenance and repairs that are not material in nature or
cost. The building, plants, structures, and equipment of the Company are
sufficient for the continued conduct of the Company's businesses after the
Closing in substantially the same manner as conducted prior to the Closing.

         3.8      ACCOUNTS RECEIVABLE

         All accounts receivable of the Company that are reflected on the
Balance Sheet or the Interim Balance Sheet or on the accounting records of the
Company as of the Closing Date (collectively, the "Accounts Receivable")
represent or will represent valid obligations arising from sales actually made
or services actually performed in the Ordinary Course of Business. Unless paid
prior to the Closing Date, the Accounts Receivable are or will be as of the
Closing Date current and collectible net of the respective reserves shown on the
Balance Sheet or the Interim Balance Sheet or on the accounting records of the
Company as of the Closing Date (which reserves are adequate and calculated
consistent with past practice and, in the case of the reserve as of the Closing
Date, will not represent a greater percentage of the Accounts Receivable as of
the Closing Date than the reserve reflected in the Interim Balance Sheet
represented of the Accounts Receivable reflected therein and will not represent
a material adverse change in the composition of such Accounts Receivable in
terms of aging). Subject to such reserves, each of the Accounts Receivable
either has been or will be collectable in full, without any set-off, within
ninety days after the day on which it first becomes due and payable. There is no
contest, claim, or right of set-off, other than returns in the Ordinary Course
of Business, under any Contract with any obligor of an Accounts Receivable
relating to the amount or validity of such Accounts Receivable. Part 3.8 of the
Disclosure Letter contains a complete and accurate list of all Accounts
Receivable as of the date of the Interim Balance Sheet, which list sets forth
the aging of such Accounts Receivable.

         3.9      INVENTORY

         All inventory of the Company, whether or not reflected in the Balance
Sheet or the Interim Balance Sheet, consists of a quality and quantity usable
and salable in the Ordinary Course of Business, except for obsolete items and
items of below-standard quality, all of which have been written off or written
down to net realizable value in the Balance Sheet or the Interim Balance Sheet
or on the accounting records of the Company as of the Closing Date, as the case
may be. All inventories not written off have been priced at the lower of cost or
market on a last in, first out basis.

         3.10     NO UNDISCLOSED LIABILITIES

         Except as set forth in Part 3.10 of the Disclosure Letter, the Company
has no liabilities or obligations of any nature (whether known or unknown and
whether absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the Balance Sheet or the Interim
Balance Sheet and current liabilities incurred in the Ordinary Course of
Business since the respective dates thereof.

         3.11     TAXES

                  (a) The Company is not required to file federal Tax Returns

Requirements. Sellers have delivered to Buyer copies of, and Part 3.11 of the
Disclosure Letter contains a complete and accurate list of, all such Tax Returns
relating to franchise taxes filed since January 1, 2003. The Company is not
taxed as a corporation, but each member of the Company is taxed on their
percentage ownership of the Company. The Company has paid, or made provision for
the payment of, all Taxes that have or may have become due pursuant to those Tax
Returns or otherwise, or pursuant to any assessment received by Sellers or the
Company, except such Taxes, if any, as are listed in Part 3.11 of the Disclosure
Letter and are being contested in good faith and as to which adequate reserves
(determined in accordance with GAAP) have been provided in the Balance Sheet and
the Interim Balance Sheet.

                  (b) Part 3.11 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.11 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Except as described in Part 3.11 of the
Disclosure Letter, neither Sellers or the Company have given or been requested
to give waivers or extensions (or is or would be subject to a waiver or
extension given by any other Person) of any statute of limitations relating to
the payment of Taxes of the Company or for which the Company may be liable.

                  (c) The charges, accruals, and reserves with respect to Taxes
on the respective books of the Company are adequate (determined in accordance
with GAAP) and are at least equal to the Company's liability for Taxes. There
exists no proposed tax assessment against the Company except as disclosed in the
Balance Sheet or in Part 3.11 of the Disclosure Letter. No consent to the
application of Section 341(f)(2) of the IRC has been filed with respect to any
property or assets held, acquired, or to be acquired by the Company. All Taxes
that the Company is or was required by Legal Requirements to withhold or collect
have been duly withheld or collected and, to the extent required, have been paid
to the proper Governmental Body or other Person.

                  (d) All Tax Returns filed by (or that include on a
consolidated basis) the Company are true, correct, and complete. There is no tax
sharing agreement that will require any payment by the Company after the date of
this Agreement. The Company is not, or nor has been within the five-year period
preceding the Closing Date, an "S" corporation. During the consistency period
(as defined in Section 338(h)(4) of the IRC with respect to the sale of the
Interests to Buyer), the Company or target affiliate (as defined in Section
338(h)(6) of the IRC with respect to the sale of the Interests to Buyer) has not
sold or nor will sell any property or assets to Buyer or to any member of the
affiliated group (as defined in Section 338(h)(5) of the IRC) that includes
Buyer. Part 3.11 of the Disclosure Letter lists all such target affiliates.

                  termination of, or the appointment of a trustee to administer,
                  any Company Plan.

                  401(a)(29).

                  (xvi) No accumulated funding deficiency, whether or not
                  waived, exists with respect to any Company Plan; no event has
                  occurred or circumstance exists that may result in an
                  accumulated funding deficiency as of the last day of the
                  current plan year of any such Plan.

                  of each such Plan in accordance with GAAP.

                  (xviii) Since the last valuation date for each Pension Plan of
                  the Company and each ERISA Affiliate of the Company, no event
                  has occurred or circumstance exists that would increase the
                  amount of benefits under any such Plan or that would cause the
                  excess of Plan assets over benefit liabilities (as defined in
                  ERISA ss. 4001) to decrease, or the amount by which benefit
                  liabilities exceed assets to increase.

                  (xiv) No reportable event (as defined in ERISA ss. 4043 and in
                  regulations issued thereunder) has occurred.

                  facts or circumstances that may give rise to any liability of
                  any Seller, the Company, or Buyer to the PBGC under Title IV
                  of ERISA.

                  or otherwise participated in, or had an obligation to
                  maintain, contribute to, or otherwise participate in, any
                  Multi-Employer Plan.

                  (xxii) Neither the Company or any ERISA Affiliate of the
                  Company have withdrawn from any Multi-Employer Plan with
                  respect to which there is any outstanding liability as of the
                  date of this Agreement. No event has occurred or circumstance
                  exists that presents a risk of the occurrence of any
                  withdrawal from, or the participation, termination,
                  reorganization, or insolvency of, any Multi-Employer Plan that
                  could result in any liability of either the Company or Buyer
                  to a Multi-Employer Plan.

                  (xxiii) Neither the Company or any ERISA Affiliate of the
                  Company have received notice from any Multi-Employer Plan that
                  it is in reorganization or is insolvent, that increased
                  contributions may be required to avoid a reduction in plan
                  benefits or the imposition of any excise tax, or that such
                  Plan intends to terminate or has terminated.

                  (xxiv) No Multi-Employer Plan to which the Company or any
                  ERISA Affiliate of the Company contributes or has contributed
                  is a party to any pending merger or asset or liability

                  employee following such employee's retirement or other
                  termination of service.

                  (xxvi) The Company has the right to modify and terminate
                  benefits to retirees (other than pensions) with respect to
                  both retired and active employees.

                  (xxii) Sellers and the Company have complied with the

                  director, officer, employee, or agent of the Company will be
                  non-deductible to the Company or subject to tax under IRC ss.
                  280G or ss. 4999; nor will the Company be required to "gross
                  up" or otherwise compensate any such person because of the

                           title, and interest in and to each of the Patents,
                           free and clear of all liens, security interests,
                           charges, encumbrances, entities, and other adverse
                           claims.

                           and proofs of working or use), are valid and
                           enforceable, and are not subject to any maintenance
                           fees or taxes or actions falling due within ninety

                           potentially interfering patent or patent application
                           of any third party.

                           (iv) No Patent is infringed or, to Sellers'

                           any process or know-how used, by the Company
                           infringes or is alleged to infringe any patent or
                           other proprietary right of any other Person.

                           (v) All products made, used, or sold under the
                           Patents have been marked with the proper patent
                           notice.

                  (e)      Trade Secrets

                           (i) With respect to each Trade Secret, the
                           documentation relating to such Trade Secret is
                           current, accurate, and sufficient in detail and
                           content to identify and explain it and to allow its
                           full and proper use without reliance on the knowledge
                           or memory of any individual.

                           (ii) Sellers and the Company have taken all
                           reasonable precautions to protect the secrecy,
                           confidentiality, and value of their Trade Secrets.

                           (iii) The Company has good title and an absolute (but
                           not necessarily exclusive) right to use the Trade
                           Secrets. The Trade Secrets are not part of the public
                           knowledge or literature, and, to Sellers' Knowledge,
                           have not been used, divulged, or appropriated either
                           for the benefit of any Person or to the detriment of
                           the Company. No Trade Secret is subject to any
                           adverse claim or has been challenged or threatened in
                           any way.

         Sellers and their agents have incurred no obligation or liability,
contingent or otherwise, for brokerage or finders' fees or agents' commissions
or other similar payment in connection with this Agreement.

         3.27     INVESTMENT INTENT AND INVESTIGATION

         Sellers are acquiring the shares of Common Stock of the Company for
their own accounts for investment and not with a view to, or for resale in
connection with, any "distribution" thereof for purposes of the Securities Act.
All the Sellers are "accredited investors" as such term is defined in Regulation
D under the Securities Act. Sellers acknowledge that the shares of Common Stock
shall be "restricted securities" within the meaning of Rule 144 ("Rule 144")
under the Securities Act, will contain a transfer restriction legend and may
only be resold pursuant to an effective registration statement filed with the
SEC under the Securities Act, or pursuant to Rule 144 or another valid exemption
from the registration requirements of the Securities Act as established by an
opinion of counsel reasonably acceptable to the Company. Sellers have been given
full access by the Company to all information concerning the business and
financial condition, properties, operations and prospects of the Company that
the Sellers have deemed relevant in connection with the issuance of the shares
of Common Stock to them. By reason of the Sellers knowledge and experience in
financial and business matters in general, the business of the Company, the
Sellers are capable of evaluating the merits and risks of making the investment
in the shares of Common Stock and are able to bear the economic risk of the
investment (including a complete loss of its investment in the shares of Common
Stock). The Sellers acknowledge that the Buyer files reports with the Securities
and Exchange Commission that are publicly available, and has provided all the
Sellers with an Annual Report on Form 10-K for the fiscal year ended December
31, 2003, and a Quarterly Report on Form 10-Q for the quarter ended September
30, 2004.

         Buyer will be entitled to control any Cleanup, any related Proceeding,
and, except as provided in the following sentence, any other Proceeding with

(as long as such acts or omissions are determined to have occurred within the
course and scope of such employment).

         8.5      TIME LIMITATIONS

                  (a) The Controlling Members will have no liability (for
indemnification or otherwise) with respect to any representation or warranty, or
covenant or obligation to be performed and complied with prior to the Closing
Date, other than those in Sections 3.3, 3.11, 3.13, and 3.19, unless on or
before December 31, 2005, Buyer notifies the Controlling Members of a claim
specifying the factual basis of that claim in reasonable detail to the extent
then known by Buyer. The Controlling Members will have no liability (for
indemnification or otherwise) with respect to Section 3.3, 3.11, 3.13, or 3.19,
unless on or before December 31, 2006, Buyer notifies the Controlling Members of
a claim specifying the factual basis of that claim in reasonable detail to the
extent known by Buyer.

                  (b) Buyer will have no liability (for indemnification or
otherwise) with respect to any representation or warranty, or covenant or
obligation to be performed and complied with prior to the Closing Date, unless
on or before December 31, 2005, the Controlling Members notify Buyer of a claim

         8.6      LIMITATIONS ON AMOUNT--SELLERS

<PAGE>

         8.8      PROCEDURE FOR INDEMNIFICATION--THIRD PARTY CLAIMS

                  (a) Promptly after receipt by an indemnified party under
Section 8.2, 8.4, or (to the extent provided in the last sentence of Section
8.3) Section 8.3 of notice of the commencement of any Proceeding against it,
such indemnified party will, if a claim is to be made against an indemnifying
party under such Section, give notice to the indemnifying party of the
commencement of such claim, but the failure to notify the indemnifying party
will not relieve the indemnifying party of any liability that it may have to any
indemnified party, except to the extent that the indemnifying party demonstrates
that the defense of such action is prejudiced by the indemnifying party's
failure to give such notice.

                  (b) If any Proceeding referred to in Section 8.8(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes, be entitled to participate in such Proceeding and, to the
extent that it wishes (unless (i) the indemnifying party is also a party to such
Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 8 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary damages that are
paid in full by the indemnifying party; and (iii) the indemnified party will
have no liability with respect to any compromise or settlement of such claims
effected without its consent. If notice is given to an indemnifying party of the
commencement of any Proceeding and the indemnifying party does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.

                  (c) Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding, but
the indemnifying party will not be bound by any determination of a Proceeding so
defended or any compromise or settlement effected without its consent (which may
not be unreasonably withheld).


                                       45
<PAGE>

                  (d) The Controlling Members and Buyer hereby consent to the
non-exclusive jurisdiction of any court in which a Proceeding is brought against
any Indemnified Person for purposes of any claim that an Indemnified Person may
have under this Agreement with respect to such Proceeding or the matters alleged
therein, and agree that process may be served on the Controlling Members or
Buyer with respect to such a claim anywhere in the world.

                  (e) Controlling Members' liability, if any, to indemnify Buyer
under this Section 8 for claims of third-parties for personal injury or property
damage or for claims arising from or related to personal injuries to Company's
employees or property (and the defense and investigation thereof) shall not
attach unless and until all applicable insurance for such claims whether carried
by Buyer or the Company is exhausted. However, if Buyer notifies the Controlling
Members of a claim for indemnification relating to such personal injury or
property damage as required hereunder, such notice shall toll the time
limitations under Section 8.5 until such matter is finally adjudicated or
disposed. Buyer agrees to maintain on Company's behalf or will cause the Company
to maintain for Company's benefit policies of insurance providing workers'
compensation, general liability, property and casualty, and
pollution/environmental coverage on a "claims made" basis with limits of not
less than $1,000,000 per occurrence for a period of at least two years
immediately following the Closing. In the event that it is determined that a
claim is not covered under the insurance agreed to be provided hereunder by
Buyer or such other insurance coverage carried by Buyer then the Controlling
Members liability will attach upon such determination.

         8.9      PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

         A claim for indemnification for any matter not involving a third-party
claim may be asserted by notice to the party from whom indemnification is
sought.

9.       GENERAL PROVISIONS

         9.1      EXPENSES

         Except as otherwise expressly provided in this Agreement, each party to
this Agreement will bear its respective expenses incurred in connection with the
preparation, execution, and performance of this Agreement and the Contemplated
Transactions, including all fees and expenses of agents, representatives,
counsel, and accountants. Sellers will cause the Company not to incur any
out-of-pocket expenses in connection with this Agreement except for professional
fees not in excess of $10,000.00. In the event of termination of this Agreement,
the obligation of each party to pay its own expenses will be subject to any
rights of such party arising from a breach of this Agreement by another party.

         9.2      PUBLIC ANNOUNCEMENTS

         Any public announcement or similar publicity with respect to this
Agreement or the Contemplated Transactions will be issued, if at all, at such
time and in such manner as Buyer determines, provided, however, that Buyer will
obtain Chevron's agreement prior to the use of its name in any press releases or
public announcements. Unless consented to by Buyer in advance or required by
Legal Requirements, prior to the Closing Sellers shall, and shall cause the
Company to, keep this Agreement strictly confidential and may not make any
disclosure of this Agreement to any Person. Sellers and Buyer will consult with
each other concerning the means by which the Company's employees, customers, and
suppliers and others having dealings with the Company will be informed of the
Contemplated Transactions, and Buyer will have the right to be present for any
such communication.

         9.3      CONFIDENTIALITY

         Between the date of this Agreement and the Closing Date, Buyer and
Sellers will maintain in confidence, and will cause the managers, members,
officers, employees, agents, and advisors of Buyer and the Company to maintain
in confidence, and not use to the detriment of another party or the Company any
written, oral, or other information obtained in confidence from another party or
the Company in connection with this Agreement or the Contemplated Transactions,
unless (a) such information is already known to such party or to others not
bound by a duty of confidentiality or such information becomes publicly
available through no fault of such party, (b) the use of such information is
necessary or appropriate in making any filing or obtaining any consent or
approval required for the consummation of the Contemplated Transactions, or (c)
the furnishing or use of such information is required by or necessary or
appropriate in connection with legal proceedings.

         If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request. Whether or not the Closing takes place, Sellers waive, and
will upon Buyer's request cause the Company to waive, any cause of action,
right, or claim arising out of the access of Buyer or its representatives to any
trade secrets or other confidential information of the Company except for the
intentional competitive misuse by Buyer of such trade secrets or confidential
information.

         9.4      NOTICES

Agreement must be in writing and will be deemed to have been duly given when (a)

         9.5      JURISDICTION; SERVICE OF PROCESS

         Any action or proceeding seeking to enforce any provision of, or based

parties in the courts of the State of Texas, County of Harris or County of
Midland or, if it has or can acquire jurisdiction, in the United States District
Court for the Southern or Western District of Texas, and each of the parties
consents to the jurisdiction of such courts (and of the appropriate appellate
courts) in any such action or proceeding and waives any objection to venue laid

         The parties agree (a) to furnish upon request to each other such

         9.7      WAIVER

         The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither the failure nor any delay by any party in
exercising any right, power, or privilege under this Agreement or the documents
referred to in 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 or the documents referred to in 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 or the documents referred to in this Agreement.

         9.8      ENTIRE AGREEMENT AND MODIFICATION

         This Agreement supersedes all prior agreements between the parties with
respect to its subject matter and constitutes (along with the documents referred
to in this Agreement) a complete and exclusive statement of the terms of the
agreement between the parties with respect to its subject matter. This Agreement
may not be amended except by a written agreement executed by the party to be
charged with the amendment.

         9.9      DISCLOSURE LETTER

                  (a) The disclosures in the Disclosure Letter, and those in any
Supplement thereto, must relate only to the representations and warranties in
the Section of the Agreement to which they expressly relate and not to any other
representation or warranty in this Agreement.

                  (b) In the event of any inconsistency between the statements
in the body of this Agreement and those in the Disclosure Letter (other than an
exception expressly set forth as such in the Disclosure Letter with respect to a
specifically identified representation or warranty), the statements in the body
of this Agreement will control.

         9.10     ASSIGNMENTS, SUCCESSORS, AND NO THIRD-PARTY RIGHTS

         Neither party may assign any of its rights under this Agreement without
the prior consent of the other parties except that Buyer may assign any of its
rights under this Agreement to any Subsidiary of Buyer. Subject to the preceding
sentence, this Agreement will apply to, be binding in all respects upon, and
inure to the benefit of the successors and permitted assigns of the parties.
Nothing expressed or referred to in this Agreement will be construed to give any
Person other than the parties to this Agreement any legal or equitable right,
remedy, or claim under or with respect to this Agreement or any provision of
this Agreement. This Agreement and all of its provisions and conditions are for
the sole and exclusive benefit of the parties to this Agreement and their
successors and assigns.

unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable.

         6.1      EVENTS OF TERMINATION

                  The Employment Period, the Executive's Basic Compensation, and
any and all other rights of the Executive under this Agreement or otherwise as
an employee of the Employer will terminate (except as otherwise provided in this
Section 6):

                  (a)      upon the death of the Executive; or

                  (b)      upon the disability of the Executive (as defined in
                           Section 6.2) immediately upon notice from either
                           party to the other;

                  (c)      for cause (as defined in Section 6.3), immediately
                           upon notice from the Employer to the Executive, or at
                           such later time as such notice may specify; and

                  (d)      without cause, immediately upon notice from either
                           party hereto or at such later time as such notice may
                           specify.

         6.2      DEFINITION OF DISABILITY

                  For purposes of Section 6.1, the Executive will be deemed to
have a "disability" if, for physical or mental reasons, the Executive is unable
to perform the essential functions of the Executive's duties under this
Agreement for 120 consecutive days, or 180 days during any twelvemonth 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 or the Non-competition Agreement
entered into on the date hereof between the Buyer and the Executive (the
"Non-Competition 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; (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, the indictment for (or its procedural
equivalent), 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      TERMINATION PAY

                  Effective upon the termination of this Agreement, the Employer
will be obligated to pay the Executive (or, in the event of his death, his
designated beneficiary as defined below) only such compensation as is provided
in this Section 6.5, and in lieu of all other amounts and in settlement and
complete release of all claims the Executive may have against the Employer. For
purposes 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 EMPLOYER FOR CAUSE. If the Employer
         terminates this Agreement for cause, the Executive will be entitled to
         receive his Salary only through the date such termination is effective.

                  (b) TERMINATION UPON DISABILITY. If this Agreement is
         terminated by either party as a result of the Executive's disability,
         as determined under Section 6.2, the Employer will continue to pay the
         Executive his Salary for the period of two months less any disability
         insurance benefits received under the disability insurance coverage
         furnished by Employer.

                  (c) TERMINATION UPON DEATH. If this Agreement is terminated
         because of the Executive's death, the Executive will be entitled to
         receive his Salary through the end of the calendar month in which his
         death occurs and one additional month.

                  (d) TERMINATION WITHOUT CAUSE. If this Agreement is terminated
         by Employer without Cause, the Executive will be entitled to receive
         his Salary as it becomes due for the remaining term of this Agreement.
         If the Executive terminates this Agreement, without Cause, Executive
         will be entitled to his Salary only through the date such termination
         is effective.

                  (e) BENEFITS. Except as otherwise provided herein, 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.

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; (c) because the
Executive possesses substantial technical expertise and skill with respect to
the Employer's business; (d) the Buyer has required that the Executive make the
covenants in this Section 7 as a condition to its purchase of the Employer's
members interests; and (e) the provisions of this Section 7 are reasonable and
necessary to prevent the improper use or disclosure of Confidential Information
and to provide the Employer with exclusive ownership of all Employee Inventions.

         7.2      AGREEMENTS 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:

                  CONFIDENTIALITY.

                           (i) During and following the Employment Period, 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.

                           (ii) Any trade secrets of the Employer will be
                  entitled to all of the protections and benefits under trade
                  secret law 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 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 submit proof
                  of the economic value of any trade secret or post a bond or
                  other security.

                           (iii) 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.

                           (iv) 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.

         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 Buyer or 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 (including any provision 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
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 Buyer would not have purchased the Executive's
membership interests under the Purchase Agreement and the Employer would not
have entered into this Agreement or employed or continued the employment of the
Executive. 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, or against the Buyer, 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 7 and 8.

         9.3      OFFSET

                  The Employer will be entitled to offset against any and all
amounts owing to the Executive under this Agreement the amount of any and all
claims that the Buyer may have against the Executive under the Purchase
Agreement.

         9.4      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.

         9.5      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.

         9.6      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.

         9.7      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.

         The parties, intending to be legally bound, agree as follows:

1.       DEFINITIONS

         Capitalized terms not expressly defined in this Agreement shall have
the meanings ascribed to them in the Purchase Agreement.

2.       ACKNOWLEDGMENTS BY SELLER

         Seller acknowledges that (a) Seller has occupied a position of trust
and confidence with the Company prior to the date hereof and has become familiar
with the following, any and all of which constitute confidential information of
the Company, (collectively the "Confidential Information"): (i) any and all

downhole injection technology, methodology or applications, of the Company and
any other information, however documented, of the Company that is a trade secret

<PAGE>

historical financial statements, financial projections and budgets, historical
and projected sales, capital spending budgets and plans, the names and
backgrounds of key personnel, personnel training and techniques and materials),
however documented; and (iii) any and all notes, analysis, compilations,

the business of the Company is international in scope, (c) its products and
services are marketed throughout the World; (d) the Company competes with other

Agreement as a condition to the Buyer's purchase of the Interests owned by
Seller and the other owners; (f) the provisions of Sections 3 and 4 of this
Agreement are reasonable and necessary to protect and preserve the Company's
business, and (g) the Company would be irreparably damaged if Seller were to
breach the covenants set forth in Sections 3 and 4 of this Agreement.

3.       CONFIDENTIAL INFORMATION

         Seller acknowledges and agrees that all Confidential Information known
or obtained by Seller, whether before or after the date hereof, is the property
of the Company. Therefore, Seller agrees that Seller will not, at any time,
disclose to any unauthorized Persons or use for his own account or for the
benefit of any third party any Confidential Information, whether Seller has such
information in Seller's memory or embodied in writing or other physical form,
without Buyer's written consent, unless and to the extent that the Confidential
Information is or becomes generally known to and available for use by the public
other than as a result of Seller's fault or the fault of any other Person bound
by a duty of confidentiality to Buyer or the Company. Seller agrees to deliver
to Buyer at the time of execution of this Agreement, and at any other time Buyer
may request, all documents, memoranda, notes, plans, records, reports, and other
documentation, models, components, devices, or computer software, whether
embodied in a disk or in other form (and all copies of all of the foregoing),
relating to the businesses, operations, or affairs of the Company and any other
Confidential Information that Seller may then possess or have under Seller's
control.

4.       NON-COMPETITION

         As an inducement for Buyer to enter into the Purchase Agreement and as
additional consideration for the consideration to be paid to Seller under the
Purchase Agreement, Seller agrees that:

                  (a) For a period of three years after the Closing:

                           (i) Seller will not, directly or indirectly, engage
                           or invest in, own, manage, operate, finance, control,
                           or participate in the ownership, management,
                           operation, financing, or control of, be employed by,

                           Seller's credit to, or render services or advice to,
                           any business involved in the installation of
                           capillary tubing in the oil and gas business;
                           provided, however, that Seller may purchase or

                                       2
<PAGE>

                           otherwise acquire up to (but not more than) five
                           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. Seller agrees
                           that this covenant is reasonable with respect to its
                           duration, geographical area, and scope.

                           (ii) Seller will not, directly or indirectly, either
                           for himself or any other Person, (A) induce or
                           attempt to induce any employee of the Company to
                           leave the employ of the Company, (B) in any way
                           interfere with the relationship between the Company
                           and any employee of the Company, (C) employ, or
                           otherwise engage as an employee, independent
                           contractor, or otherwise, any employee of the
                           Company, or (D) induce or attempt to induce any
                           customer, supplier, licensee, or business relation of
                           the Company to cease doing business with the Company,
                           or in any way interfere with the relationship between
                           any customer, supplier, licensee, or business
                           relation of the Company.

                  (b) In the event of a breach by Seller of any covenant set
         forth in Subsection 4(a) of this Agreement, the term of such covenant
         will be extended by the period of the duration of such breach.

5.       REMEDIES

         If Seller breaches the covenants set forth in Sections 3 or 4 of this
Agreement, Buyer and the Company will be entitled to the following remedies:

                  (a) Damages from Seller;

                  (b) To offset against any and all amounts owing to Seller
         under the Purchase Agreement any and all amounts which Buyer or the
         Company claim under Subsection 6(a) of this Agreement; and

                  (c) In addition to its right to damages and any other rights
         it may have, to obtain injunctive or other equitable relief to restrain
         any breach or threatened breach or otherwise to specifically enforce
         the provisions of Sections 3 and 4 of this Agreement, it being agreed
         that money damages alone would be inadequate to compensate the Buyer
         and the Company and would be an inadequate remedy for such breach.

                  (d) The rights and remedies of the parties to this Agreement
         are cumulative and not alternative.

6.       SUCCESSORS AND ASSIGNS

         This Agreement will be binding upon Buyer, the Company and Seller and
will inure to the benefit of Buyer and the Company and their affiliates,
successors and assigns.

7.       WAIVER

         Neither the failure nor any delay by any 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.

8.       GOVERNING LAW

         This Agreement will be governed by the laws of the State of Texas
without regard to conflicts of laws principles.

9.       JURISDICTION; SERVICE OF PROCESS

on any right arising out of, this Agreement may be brought against any of the
parties in the courts of the State of Texas, County of Harris or County of
Midland or, if it has or can acquire jurisdiction, in the United States District
Court for the Western or Southern District of Texas, and each of the parties
consents to the jurisdiction of such courts (and of the appropriate appellate
courts) in any such action or proceeding and waives any objection to venue laid
therein. Process in any action or proceeding referred to in the preceding
sentence may be served on any party anywhere in the world.

10.      SEVERABILITY

         Whenever possible each provision and term of this Agreement will be
interpreted in a manner to be effective and valid but if any provision or term
of this Agreement is held to be prohibited by or invalid, then such provision or
term will be ineffective only to the extent of such prohibition or invalidity,
without invalidating or affecting in any manner whatsoever the remainder of such
provision or term or the remaining provisions or terms of this Agreement. If any
of the covenants set forth in Section 4 of this Agreement are held to be
unreasonable, arbitrary, or against public policy, such covenants will be
considered divisible with respect to scope, time, and geographic area, and in
such lesser scope, time and geographic area, will be effective, binding and

disclose to any unauthorized Persons or use for his own account or for the
benefit of any third party any Confidential Information, whether Seller has such
information in Seller's memory or embodied in writing or other physical form,
without Buyer's written consent, unless and to the extent that the Confidential
Information is or becomes generally known to and available for use by the public
other than as a result of Seller's fault or the fault of any other Person bound
by a duty of confidentiality to Buyer or the Company. Seller agrees to deliver
to Buyer at the time of execution of this Agreement, and at any other time Buyer

Confidential Information that Seller may then possess or have under Seller's
control.

                           (i) Seller will not, directly or indirectly, engage
                           or invest in, own, manage, operate, finance, control,
                           or participate in the ownership, management,
                           operation, financing, or control of, be employed by,

                           any business whose products or activities compete in
                           whole or in part with the pro ducts or activities of
                           the Company; provided, however, that Seller may


                                       2
<PAGE>

                           purchase or otherwise acquire up to (but not more
                           than) five 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. Seller agrees
                           that this covenant is reasonable with respect to its
                           duration, geographical area, and scope.

                           (ii) Seller will not, directly or indirectly, either
                           for himself or any other Person, (A) induce or
                           attempt to induce any employee of the Company to
                           leave the employ of the Company, (B) in any way
                           interfere with the relationship between the Company
                           and any employee of the Company, (C) employ, or
                           otherwise engage as an employee, independent
                           contractor, or otherwise, any employee of the
                           Company, or (D) induce or attempt to induce any
                           customer, supplier, licensee, or business relation of
                           the Company to cease doing business with the Company,
                           or in any way interfere with the relationship between
                           any customer, supplier, licensee, or business
                           relation of the Company.

                           (iii) Seller will not, directly or indirectly, either
                           for himself or any other Person, solicit the business
                           of any Person known to Seller to be a customer of the
                           Company, whether or not Seller had personal contact
                           with such Person with respect to activities which
                           compete in whole or in part with the activities of
                           the Company;

                  (b) In the event of a breach by Seller of any covenant set
         forth in Subsection 4(a) of this Agreement, the term of such covenant
         will be extended by the period of the duration of such breach;

                  (c) Seller will not, at any time during or after the three
         year period, disparage Buyer or the Company, or any of their
         shareholders, directors, officers, employees, or agents; and

                  (d) Seller will, for a period of three years after the
         Closing, within ten days after accepting any employment, advise Buyer
         of the identity of any employer of Seller. Buyer or the Company may
         serve notice upon each such employer that Seller is bound by this
         Agreement and furnish each such employer with a copy of this Agreement
         or relevant portions thereof.

6.       REMEDIES

         If Seller breaches the covenants set forth in Sections 3 or 4 of this
Agreement, Buyer and the Company will be entitled to the following remedies:

                  (a) Damages from Seller;

                                       3
<PAGE>

                  (b) To offset against any and all amounts owing to Seller
         under the Purchase Agreement any and all amounts which Buyer or the
         Company claim under Subsection 6(a) of this Agreement; and

                  (c) In addition to its right to damages and any other rights
         it may have, to obtain injunctive or other equitable relief to restrain
         any breach or threatened breach or otherwise to specifically enforce
         the provisions of Sections 3 and 4 of this Agreement, it being agreed
         that money damages alone would be inadequate to compensate the Buyer
         and the Company and would be an inadequate remedy for such breach.

                  (d) The rights and remedies of the parties to this Agreement
         are cumulative and not alternative.

7.       SUCCESSORS AND ASSIGNS

         This Agreement will be binding upon Buyer, the Company and Seller and
will inure to the benefit of Buyer and the Company and their affiliates,
successors and assigns and Seller and Seller's assigns, heirs and legal
representatives.

8.       WAIVER

         The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither the failure nor any delay by any 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.       GOVERNING LAW

         This Agreement will be governed by the laws of the State of Texas
without regard to conflicts of laws principles.

10.      JURISDICTION; SERVICE OF PROCESS

         Any action or proceeding seeking to enforce any provision of, or based
on any right arising out of, this Agreement may be brought against any of the
parties in the courts of the State of Texas, County of Harris or County of
Midland or, if it has or can acquire jurisdiction, in the United States District
Court for the Northern or Southern District of Texas, and each of the parties
consents to the jurisdiction of such courts (and of the appropriate appellate
courts) in any such action or proceeding and waives any objection to venue laid
therein. Process in any action or proceeding referred to in the preceding
sentence may be served on any party anywhere in the world.


<PAGE>

11.      SEVERABILITY

         Whenever possible each provision and term of this Agreement will be
interpreted in a manner to be effective and valid but if any provision or term
of this Agreement is held to be prohibited by or invalid, then such provision or
term will be ineffective only to the extent of such prohibition or invalidity,
without invalidating or affecting in any manner whatsoever the remainder of such
provision or term or the remaining provisions or terms of this Agreement. If any
of the covenants set forth in Section 4 of this Agreement are held to be
unreasonable, arbitrary, or against public policy, such covenants will be
considered divisible with respect to scope, time, and geographic area, and in
such lesser scope, time and geographic area, will be effective, binding and
enforceable against Seller.

12.      COUNTERPARTS

         This Agreement may be executed in one or more counterparts, each of
which will be deemed to be an original copy of this Agreement and all of which,
when taken together, will be deemed to constitute one and the same agreement.

13.      SECTION HEADINGS, CONSTRUCTION

only and will not affect its construction or interpretation. All references to
"Section" or "Sections" refer to the corresponding Section or Sections of this
Agreement unless otherwise specified. All words used in this Agreement will be
construed to be of such gender or number as the circumstances require. Unless
otherwise expressly provided, the word "including" does not limit the preceding
words or terms.

Agreement must be in writing and will be deemed to have been duly given when (a)
