ITEM 1. CHANGES IN CONTROL OF REGISTRANT.

        On December 5, 1996, Herlin Industries, Inc. ("Herlin") purchased 98% of
the common stock (the "Common Stock") and all of the preferred stock (the
"Preferred Stock") of Catalyst Energy Services, Inc. ("CESI"). Collectively, the
Common Stock and the Preferred Stock are hereinafter referred to as the
"Shares." St. James Capital Partners, L.P. ("St. James"), of which St. James
Capital Corp. ("SJCC") is the general partner, owns 80% of the common stock of
Herlin. Randolph W. Herring and Kevin J. Millin each own 10% of the common stock
of Herlin. Each of St. James, SJCC, Mr. Herring and Mr. Millin are deemed to own
beneficially, as a Section 13 group, 98% of the common stock of CESI solely
through their ownership of Herlin.

        Herlin purchased the Shares of CESI from Catalyst Capital Partners I,
Ltd., The Catalyst Group, Inc., Catalyst Compressor, Inc., Andrew Cormier, the
Matthew James Cormier Trust, the Paige Sonya Cormier Trust, Troy Cormier, Gary
Farr, Harry Ardoin, Gary Cryer, Mike Richards and Steve Gillioz in a privately
negotiated transaction. Herlin paid $.70 per share for the Common Stock and
$1.00 per share for the Preferred Stock or $8,893,008.60 for all of the Common
Stock and $319,174 for the Preferred Stock. In order to finance the purchase of
the Shares by Herlin, Mr. Herring contributed $250,000 of his personal funds;
Mr. Millin contributed $250,000 of his personal funds; St. James contributed
$1,000,000 from its current working capital; Herlin borrowed $3,000,000 pursuant
to a 10% promissory note in favor of St. James; and Herlin, CESI, Manifold Valve
Services, Inc. ("MVSI") and Compressor Dynamics, Inc. ("CDI") jointly and
severally borrowed $6,300,000 pursuant to a term loan in favor of Comerica
Bank-Texas ("Comerica"). The interest rate on the term loan is the Comerica
prime rate. The remainder of the consideration was obtained from a revolving
loan borrowed by Herlin, CESI, MVSI and CDI, jointly and severally, in favor of
Comerica at an interest rate of either the Comerica prime or LIBOR plus 275
basis points, at the election of Comerica.

        Certain of the directors of CESI resigned, simultaneously with the
purchase of the Shares, and the vacancies thereby created were filled by Mr.
Herring and Mr. Millin pursuant to action by the Board of Directors of CESI.

repair and maintenance. Except as disclosed on Schedule 4.13, all leases of
fixed assets are in full force and effect and binding upon the parties thereto
and, to the best knowledge of the Selling Stockholders, none of the parties
thereto is in breach of any material provision thereof.

      4.14 OTHER ASSETS. Schedule 4.14 sets forth a list and summary description
of all properties and assets owned by the Company and the Subsidiaries
classified as "Other Assets" in the Financial Statements, and which have a net
book value of $10,000 or more per item. Except as indicated in Schedule 4.14,
since the Balance Sheet Date, neither the Company nor any of the Subsidiaries
has acquired or sold or otherwise disposed of any of such properties or assets
which, singularly or in the aggregate, are material to the operation of the
Company's or any of the Subsidiaries' businesses as presently constituted. Since
the Balance Sheet Date, the Company and the Subsidiaries have conducted their
business operations in a manner substantially the same as conducted by the
Company or the Subsidiaries immediately prior to the Balance Sheet Date.

      4.15  CONTRACTS AND AGREEMENTS; ADVERSE RESTRICTIONS.

            (a) Other than CDI equipment leases and master service agreements
entered into in the ordinary course of business, Schedule 4.15 sets forth a list
of all contracts, leases and agreements other than licenses and rights included
in Schedule 4.12 and leases included in Schedule 4.13, contracts and agreements
included in Schedule 4.19, any individual customer service agreements or
purchase orders which are subject to termination by the Company or any of the
Subsidiaries without penalty upon 90 days' notice or less, and any agreements
providing for annual expenditures by, or revenues to, the Company or any of the
Subsidiaries of more than $20,000 to which the Company or any of the
Subsidiaries is a party or by which it or any of its property is bound
(including, but not limited to, joint venture or partnership agreements,
contracts with any labor organizations, loan agreements, bonds, mortgages,
liens, pledges or other security agreements). All such contracts and agreements
included in Schedule 4.15 are in full force and effect and binding upon the
parties thereto and neither the Company nor, to the best knowledge of the
Selling Stockholders, any of the other parties thereto is in breach of any of
the material provisions thereof and, to the best knowledge of the Selling
Stockholders, no condition exists that with notice or lapse of time or both
would constitute a breach or default.

            (b) Except as set forth and identified in Schedules 4.9, 4.11, 4.12,
4.13, 4.15, 4.16, 4.17 or 4.19, neither the Company nor either of the
Subsidiaries is a party to any contract, lease, agreement or other commitment or
instrument or subject to any charter or other corporate restriction or subject
to any restriction or condition contained in any permit, license, judgment,
order, writ, injunction, decree or award which, singularly or in the aggregate,
materially and adversely affects

                                    -14-

<PAGE>



or is likely to materially and adversely affect the current existing business,
operations, properties, assets or condition (financial or otherwise) of the
Company and the Subsidiaries taken as a whole.

      4.16  TITLE AND LIENS.

            (a) The Company and the Subsidiaries have good and indefeasible
title to all properties, contracts, assets and leasehold estates, real and
personal, owned and used in their respective businesses, including, without
limitation, those reflected in the Schedules attached hereto, subject to no
mortgage, pledge, lien, conditional sales agreement, encumbrance, charge,
easement, right-of-way, encroachment, protrusion and other similar restrictions
(collectively, "Encumbrances"), except for Encumbrances listed in Schedule 4.16
and Permitted Encumbrances. Neither the Company nor either of the Subsidiaries
own any real property. Without limitation to the foregoing, except as set forth
on Schedule 4.16, no Landlord has placed an Encumbrance on the Landlord's
interest in such Landlord's Real Property Lease which would have priority over
the leasehold estate created by such Real Property Lease.

            (b) Without limiting the foregoing, the condition of title to or
interest in the Company's and the Subsidiaries' Leased Real Property is as
follows: to the best knowledge of the Selling Stockholders, except as set forth
in Schedules 4.13, 4.15 or 4.16, there are no leases, tenancy agreements,
easements, covenants, restrictions or any other instruments, agreements or
arrangements which create in or confer on any party other than the Company or
the Subsidiaries the right to occupy or possess all or any portion of the Leased
Real Property or create in or confer on any such party any right, title or
interest in or to the Leased Real Property or any portion thereof or any
interest therein; no party other than the Company or the Subsidiaries occupies
or possesses the Leased Real Property or any portion thereof; to the best
knowledge of the Selling Stockholders, there is legal and adequate ingress and
egress between each tract of Leased Real Property and an adjacent (or, if none,
the closest) public roadway; to the best knowledge of the Selling Stockholders,
the Leased Real Property is properly zoned in order to allow its current use in
the Company's and the Subsidiaries' businesses; no condemnation proceedings are
pending or, to the best knowledge of the Selling Stockholders, threatened that
could adversely affect the Leased Real Property and there are no claims or
demands pending or, to the best knowledge of the Selling Stockholders,
threatened by any party against the Leased Real Property which, if valid, would
create in, or confer on, any party other than the Company or the Subsidiaries,
any right, title or interest in or to the Leased Real Property or any portion
thereof.

            (c) Except as identified on Schedule 4.16, true, complete and
accurate copies of the Real Property Leases, have been made available to
Purchaser, and each of such leases is in full force and effect, to the best
knowledge of the Selling Stockholders, without modification or amendment from
the form delivered. Each such lease constitutes the legal, valid and binding

                                    -15-

<PAGE>



obligation of the Company and/or the Subsidiaries, as applicable, and, to the
best knowledge of the Selling Stockholders, the other respective parties
thereto. There exists no event or condition which, with notice or lapse of time,
or both, would constitute a default by the Company or either of the
Subsidiaries. All rentals and other payments due under such leases have been
paid in full and the Company and the Subsidiaries have performed all obligations
required to be performed by them thereunder and Schedule 4.16 sets forth a true
and accurate list of the rentals and other sums payable under the Real Property
Leases. No option has been exercised under any of such leases except options
whose exercise has been evidenced by a written document, a true, complete and
accurate copy of which has been made available to Purchaser with the
corresponding lease. Except as identified on Schedule 4.16, none of the leases
require the consent or approval of the other party to the lease in connection
with a transfer of control of the Company or the granting of a lien thereon or
security interest therein by Purchaser upon the transfer of control of the
Company to Purchaser. Neither the Company nor either of the Subsidiaries nor, to
the Selling Stockholders' best knowledge, any of the other parties to the
leases, is in default under any of the leases, which default would give either
party thereto the right to terminate such lease or give rise to the right on the
part of either party to any penalty or set-off.

      4.17 INSURANCE. The Company and the Subsidiaries maintain such policies of
casualty, liability and other insurance as they have determined to be
appropriate under the circumstances. Such policies, with respect to their
amounts and types of coverage, are considered by management of the Company and
the Subsidiaries to be adequate to insure against risks to which the Company and
the Subsidiaries are exposed in the ordinary course of business. Schedule 4.17
accurately identifies the types and coverage amounts of such insurance coverage.

      4.18 PERSONNEL. Schedule 4.18 sets forth a list of all officers,
directors, employees, and consultants and agents with whom the Company or any of
the Subsidiaries have agreements not terminable at the will of the Company or
any of the Subsidiaries (by type or classification) and their respective rates
of compensation (including the portions thereof attributable to bonuses),
including any other salary, bonus or other payment arrangement made with any of
them.

      4.19  BENEFIT PLANS AND LABOR MATTERS.

            (a) Schedule 4.19 sets forth a list (copies or descriptions of which
have been made available to the Purchaser) of all of the following agreements or
plans of the Company, any Subsidiary or any other entity which, together with
the Company or any Subsidiary, constitutes a single employer within the meaning
of Section 414 of the Code (hereinafter collectively referred to as the "Company
Group") which are presently in effect or which have been in effect at any time
during the two years prior to the Closing Date, or, in the case of documents
referred to in subparts (ii) below, have been in effect at any time prior to the
date hereof:

                                    -16-

<PAGE>



      (i)   union, collective bargaining, or similar agreements;

      (ii)  "employee welfare benefit plans" and "employee pension benefit
            plans," as defined in Sections 3(1) and 3(2) of ERISA; and

      (iii) any other pension, profit sharing, retirement, deferred
            compensation, stock purchase, stock option, incentive, bonus,
            vacation, severance, disability, health, hospitalization, medical,
            life insurance, vision, dental, prescription drug, supplemental
            unemployment, layoff, automobile, apprenticeship and training, day
            care, scholarship, group legal benefits, fringe benefit, or other
            employee benefit plan, program, policy, or arrangement, whether
            written or unwritten, formal or informal, which any member of the
            Company Group maintains or to which any member of the Company Group
            has any outstanding, present, or future obligation to contribute to
            or make payments under, whether voluntary, contingent, or otherwise
            (the plans, programs, policies, or arrangements described in
            subparts (ii) or (iii) as herein collectively referred to as the
            "Company Plans").

      (iv)  the Selling Stockholders have delivered to the Purchaser a copy of
            all 1994 and 1995 governmental filings, Internal Revenue Service
            determination letters, financial statements, and actuarial reports,
            including but not limited to, the most recent financial statements
            of each Qualified Plan, the most recent actuarial report, if any,
            for each employee pension benefit plan and Internal Revenue Service
            Forms 5500 for each Company Plan for the relevant plan years of 1994
            and 1995. All financial statements and actuarial reports have been
            prepared in accordance with generally accepted accounting principles
            and actuarial principles, applied on a uniform and consistent basis.

          (b) Schedule 4.19 identifies each of the Company Plans which are
Qualified Plans. A copy of all determinations by the Internal Revenue Service
respecting the Qualified Plans have been delivered to the Purchaser. All of such
determination letters remain in effect and have not been revoked. No Qualified
Plan has been amended in any material respect since the issuance of the most
recent determination letter. No issue concerning qualification of any Qualified
Plan is pending before or, to the best knowledge and belief of the Selling
Stockholders, threatened by the Internal Revenue Service. Each Qualified Plan
has been administered according to its terms, except for those terms which are
inconsistent with the changes required by statutes, regulations, and rulings for
which changes are not yet required to be made, in which case each Qualified Plan
has been administered in accordance with the provisions of the statutes,
regulations, and rulings, and no member of the Company Group nor any fiduciary
of any Qualified Plan has done anything which would adversely affect the
qualified status of any Qualified Plan or any related trust. To the best
knowledge of the

                                    -17-

<PAGE>



Selling Stockholders, each Qualified Plan currently complies with the
requirements under Section 401(a) of the Code and, if applicable Section 401(k)
of the Code, other than changes required by statutes, regulations, and rulings
for which amendments are not yet required.

          (c) To the best knowledge of the Selling Stockholders, each member of
the Company Group is in compliance with the requirements prescribed by any and
all statutes, orders, governmental rules, and regulations applicable to the
Company Plans and all reports and disclosures relating to the Company Plans
required to be filed with or furnished to governmental agencies, participants or
beneficiaries prior to the Closing Date have been or will be filed or furnished
in a timely manner and in accordance with applicable law.

          (d) Except as listed in Schedule 4.19, no termination or partial
termination of any existing Company Plan has occurred, nor has a notice of
intent to terminate any existing Company Plan been issued by a member of the
Company Group. The Pension Benefit Guaranty Corporation has not instituted, and,
to the best knowledge of the Selling Stockholders, is not expected to institute,
any proceedings to terminate any Company Plan. To the best knowledge of the
Selling Stockholders, each employee pension benefit plan listed as terminated in
Schedule 4.19 has met the requirements for standard termination of
single-employer plans contained in Section 4041(b) of ERISA.

          (e) No Company Plan has suffered any "accumulated funding deficiency,"
within the meaning of ERISA Section 302 and Section 412 of the Code, whether or
not waived, and if any Company Plan were terminated on the Closing Date, no
member of the Company Group would have any liability to any participants or
beneficiaries as a result of the termination except to the extent of funds set
aside for such purpose or reflected as reserved for such purpose on the
Financial Statements. Each member of the Company Group has made full and timely
payment of, or has accrued pending full and timely payment, all amounts which
are required under the terms of each Company Plan and in accordance with
applicable laws to be paid as a contribution to each Company Plan. Schedule 4.19
sets forth the unfunded accrued liabilities of each "defined benefit plan," as
defined in Section 3(35) of ERISA, as of the date indicated by the actuaries for
such Plan.

          (f) Except as listed in Schedule 4.19, no member of the Company Group
has any past, present or future obligation or liability to contribute to any
"multiemployer plan," as defined in ERISA Section 3(37) (a "Multiemployer
Plan"). Schedule 4.19 sets forth all Company Group contributions made to each
Multiemployer Plan for the twelve months ending on the last day of its most
recent fiscal year.

          (g) No member of the Company Group has completely or partially
withdrawn from any Multiemployer Plan within the meaning of the Multiemployer
Pension Plan Amendments Act

                                    -18-

<PAGE>



of 1980. No member of the Company Group has suffered a 70% decline in
"contribution base units," within the meaning of ERISA Section 4205(b)(1)(A), in
any plan year beginning after 1979.

          (h) To the best knowledge of the Selling Stockholders, no member of
the Company Group has any liability to the Pension Benefit Guaranty Corporation.
With respect to any Company Plan or any member of the Company Group, no
termination liability to the Pension Benefit Guaranty Corporation or withdrawal
liability to any Multiemployer Plan has been or is expected to be incurred or
would be incurred if any Company Plan were terminated on the Closing Date or if
any member of the Company Group were to withdraw from any Multiemployer Plan on
the Closing Date. Except as may be caused by the transactions contemplated
herein, there has been no "reportable event," as defined in Section 4043(b) of
ERISA, with any respect to any Company Plan, for which notice has not been
waived.

          (i) No member of the Company Group is liable or has been advised that
it is liable for any funding taxes under Code Sections 413(b)(6) or 4971 on
account of an accumulated funding deficiency of any Multiemployer Plan to which
any member of the Company Group has contributed or is required to contribute.

          (j) No member of the Company Group has made or is obligated to make
any nondeductible contributions to any Qualified Plan.

          (k) Except as listed in Schedule 4.19, no Company Plan is subject to
Title IV of ERISA.

          (l) Except as listed in Schedule 4.19, no member of the Company Group
shall increase the rate of compensation payable or to become payable to any of
its officers, directors, employees, consultants or agents, except in accordance
with established wage policies, or make any commitment or incur any liability to
any labor union (not currently set forth in the collective bargaining
agreement), or pay or agree to pay any bonuses or severance pay other than in
accordance with currently established policies or agreements.

          (m) No member of the Company Group is obligated, contingently or
otherwise, under any agreement to pay any amount which will be treated as an
"excess parachute payment," as defined in Code Section 280G(b), and any
"parachute payment," as defined in Code Section 280G(b), with respect to which
any member of the Company Group is obligated, contingently or otherwise, will be
deductible under state and federal income tax laws and will not give rise to an
excise tax under Code Section 4999.

(v) knows of any controversies pending or threatened by any current or former
employees or any labor or other collective bargaining unit representing any

stoppage or otherwise have a material effect on the business of any member of
the Company Group, (vi) knows of any organizational effort being made or
threatened by or on behalf of any labor union with respect to employees of the
Company Group, (vii) knows of any key employee or group of employees of the

or the Subsidiaries.

          (o) Except as set forth in Schedule 4.19, no member of the Company
Group is liable for any unpaid wages, bonuses or commissions, or taxes,
penalties, assessments or forfeitures arising from any employment matter.

          (p) To the best knowledge of the Selling Stockholders, no member of
the Company Group has committed any violations of the Civil Rights Act of 1964,
as amended, the federal wage and hour laws, or federal or state income,
unemployment, or social security withholding laws.

          (q) To the best knowledge of the Selling Stockholders, each member of
the Company Group has complied with applicable workers compensation statutes.

          (r) To the best knowledge of the Selling Stockholders, no member of
the Company Group nor any other "disqualified person" or "party in interests,"
as defined in Section 4975 of the Code and ERISA Section 3(14), respectively,
has engaged in any "prohibited transaction," as defined in Section 4975 of the
Code or ERISA Section 406, and all "fiduciaries," as defined in Section 3(21) of
ERISA, with respect to the Company Plans have complied in all respects with the
requirements of Section 404 of ERISA. To the best knowledge of the Selling
Stockholders, neither any member of the Company Group nor any party in interest
or disqualified person has taken or omitted any action with respect to the
Company Plans which could lead to the imposition of an excise tax under the Code
or a fine under ERISA.

          (s) Other than routine claims for benefits (as provided for in the
Company Plans), there are no actions, audits, investigations, suits, or claims
pending, or, to the best knowledge of the Selling Stockholders, threatened
against any of the Company Plans or any fiduciary of any of the Company Plans or
against the assets of any of the Company Plans.

                                    -20-

          (t) To the best of Selling Stockholders' knowledge, the consummation
of the transactions contemplated hereby will not accelerate or increase any
liability to the Company under any Company Plan because of an acceleration or
increase of any of the rights or benefits to which employees may be entitled
thereunder.

          (u) From the date hereof until the Closing Date, no member of the
Company Group shall amend any Company Plans (except to the extent necessary to
maintain compliance with the Code or ERISA), increase any benefits or rights
under any Company Plan, or adopt any new plan, program, policy, or arrangement
which, if it existed as of the Closing Date, would constitute a Company Plan.

          (v) Except as listed in Schedule 4.19, or as required by law, no
member of the Company Group has any obligation to any retired or former
employee, or any current employee upon retirement, under any Company Plan, and
any Company Plan can be terminated without resulting in any liability to the
Company or any of the Subsidiaries or to the Purchaser for any additional
penalties, premiums, fees, or any other charges. To the extent such obligations
exist, such obligations are fully funded or adequately reserved for by the
Company or Subsidiaries and shall be liabilities to be retained by the Company

respects with the continuation coverage requirements of Title X of COBRA.

compliance with federal and state securities laws and without limiting or
affecting the other representations, warranties, covenants or agreements of the
Selling Stockholders hereunder, the Purchaser further represents and warrants as

            access to such information as it deems necessary for the purchase of
            the Shares, and has had, to the best of its knowledge, full access
            to all other information of the Company requested by the Purchaser;

      (ii)  The Purchaser understands that the sale of the Shares hereunder is

            to be transferred hereunder have not been registered under the Act

            applicable securities laws of such states or unless an exemption

            the holder, which counsel and opinion are reasonably satisfactory to

                                 ARTICLE VIII

                           TERMINATION AND SURVIVAL

    9.1 EVENTS OF TERMINATION. Notwithstanding any other provision hereof, this
Agreement shall terminate upon the occurrence of any of the following events:

                                    -39-

<PAGE>



          (a)   the written consent of the Representative and the Purchaser;

          (b) by written notice of the Purchaser or the Representative, without
prejudice to other rights and remedies which the terminating party may have
(provided the terminating party is not otherwise in material default or breach
of this Agreement, or has failed or refused to close without justification
hereunder), if the Purchaser or any of the Selling Stockholders, as applicable,
shall (i) materially fail or have failed to perform the covenants or agreements
required to be performed prior to the Closing Date by such party hereunder, or
(ii) materially breach or have breached any of its representations or warranties
contained herein;

          (c) by either the Representative or the Purchaser in writing, without
liability, if there shall be any order, writ, injunction or decree of any court
or governmental or regulatory agency binding on Purchaser or any Selling
Stockholder, which prohibits or restrains Purchaser or any Selling Stockholder
from consummating the transactions contemplated hereby, provided that Purchaser
and Selling Stockholders shall have used their best efforts to have any such
order, writ, injunction or decree lifted and the same shall not have been lifted
within 30 days after entry by any such court or governmental or regulatory
agency; or

          (d) the written notice by the Purchaser or the Representative on or
after December 4, 1996 if the Closing has not occurred by such date due to the
failure of any condition to Closing in Section 7.1 or 7.2 hereof not due to a
breach or default of a party hereto, provided that as of such date neither the
Purchaser nor any of the Selling Stockholders is in default or that both the
Purchaser and one or more of the Selling Stockholders are in default under this
Agreement.

      9.2 EFFECT OF TERMINATION. The following provisions shall apply in the
event of a termination of this Agreement:

          (a) In the event this Agreement is terminated by the Representative
pursuant to Section 9.1(b), the Representative shall be entitled to retain the
Prepayment on behalf of the Selling Stockholders and the Representative shall
distribute the Prepayment to the Selling Stockholders, in the applicable pro
rata portions or to the Company, as agreed by the Representative and the Selling
Stockholders. Purchaser and the Selling Stockholders hereby agree in the case of
this clause (a) of Section 9.2 that (i) the Selling Stockholders' damages for
Purchaser's default are difficult or impossible to determine, (ii) Purchaser's
payment of the Prepayment is deemed a reasonable estimate of the Selling
Stockholders' potential damages, (iii) such payment is not a penalty or
forfeiture, and (iv) upon the Representative's retention of the Prepayment on
behalf of the Selling Stockholders, neither the Purchaser nor any Selling
Stockholders shall have any further liability or obligation to one another in
connection with this Agreement and the transactions contemplated hereby except
as otherwise provided in the Confidentiality Agreement.

                                    -40-

<PAGE>



          (b) In the event this Agreement is terminated by the Purchaser
pursuant to Section 9.1(b) or by any party pursuant to Section 9.1(a), 9.1(c) or
9.1(d) or for failure of either of the conditions to Closing of Purchaser set
forth in Sections 7.1(j) and 7.1(m) hereof, the Prepayment shall be promptly
returned by the Representative to the Purchaser.

          (c) Solely for purposes of determining whether termination of this
Agreement is permissible by any party pursuant to Section 9.1(b), material
failure to perform the covenants or agreements required to be performed by the
Selling Stockholders or the Purchaser prior to the Closing Date or material
breach of any representations or warranties shall be deemed to exist if such
failure to perform and/or breach may reasonably be expected to result in
monetary damages in the aggregate to the Purchaser or the Selling Stockholders
in excess of $150,000.

          (d) If this Agreement is terminated by the Representative or by the
Purchaser as permitted under Section 9.1 and not as the result of the failure of
any party to perform its obligations hereunder, such termination shall be
without liability to any party to this Agreement or any stockholder, director,
officer, employee, agent or representative of such party.

          (e) The Purchaser and the Selling Stockholders acknowledge that the
Shares are not readily available in the open market and the assets of the
Company and the Subsidiaries are unique and specifically identifiable.
Accordingly, the Purchaser and the Selling Stockholders further agree and
stipulate that if the Closing does not occur because of the failure of any
Selling Stockholder to perform its obligations hereunder, (i) monetary damages
and any other remedy at law will not be adequate, (ii) the Purchaser shall be
entitled to specific performance as the remedy for such breach, (iii) each party
hereto agrees to waive any objection to the remedy of specific performance, (iv)
each party agrees that the granting of specific performance by any court will
not be deemed to be harsh or oppressive to the party who is ordered specifically
to perform its obligations under this Agreement, and (v) in connection with any
action for specific performance that meets the foregoing criteria, the Purchaser
shall be entitled to reasonable attorneys' fees and other costs of prosecuting
or defending such action.

          (f) The right to seek specific performance hereunder shall not
preclude the Purchaser from seeking any other remedy at law or in equity for a
breach of any obligation, representation, warranty, covenant or agreement by any
Selling Stockholder hereunder.

    9.3 SURVIVAL. The liability of the Selling Stockholders for the breach of
any of the representations and warranties of the Selling Stockholders set forth
in Article IV shall be limited to claims for which the Purchaser delivers
written notice to the Selling Stockholders within 16 months after the Closing
Date. The liability of the Purchaser for the breach of any of the
representations and warranties of the Purchaser set forth in Article V shall be
limited to claims for which Selling

                                    -41-

<PAGE>



Stockholders shall deliver written notice to the Purchaser within 16 months
after the Closing Date. Notwithstanding the foregoing, the survival period for
the representations and warranties in Sections 4.2 and 4.10 shall be the
applicable statute of limitations.


                                   ARTICLE X
                                INDEMNIFICATION

    10.1 INDEMNIFICATION OF THE SELLING STOCKHOLDERS. The Purchaser, from and
after the Closing Date, shall indemnify and hold the Selling Stockholders
harmless from and against any and all Damages suffered by Selling Stockholders
as a result of, caused by, arising out of, or in any way relating to any
misrepresentation, breach of warranty, or nonfulfillment of any agreement or
covenant on the part of the Purchaser under this Agreement or any
misrepresentation in or omission from any list, schedule, certificate, or other
instrument furnished or to be furnished to the Selling Stockholders by the
Purchaser pursuant to the terms of this Agreement.

    10.2 INDEMNIFICATION OF THE PURCHASER. The Selling Stockholders, severally
but not jointly, and on the basis of the Seller Percentages shall indemnify and
hold the Company, the Subsidiaries and the Purchaser harmless from and against
any and all Damages suffered by the Company, any of the Subsidiaries or the
Purchaser as a result of, caused by, arising out of, or in any way relating to
any misrepresentation, breach of warranty, or nonfulfillment of any agreement or
covenant on the part of the Selling Stockholders under this Agreement or any
misrepresentation in or omission from any list, schedule, certificate, or other
instrument furnished or to be furnished to the Purchaser by the Selling
Stockholders, the Company or any of the Subsidiaries pursuant to the terms of
this Agreement.

    10.3 DEMANDS. Each indemnified party hereunder agrees that promptly upon its
discovery of facts giving rise to a claim for indemnity under the provisions of
this Agreement, including receipt by it of notice of any demand, assertion,
claim, action or proceeding, judicial or otherwise, by any third party (such
third party actions being collectively referred to herein as the "Claim"), with
respect to any matter as to which it claims to be entitled to indemnity under
the provisions of this Agreement, it will give prompt notice thereof in writing
to the indemnifying party, together with a statement of such information
respecting any of the foregoing as it shall have. Such notice shall include a
formal demand for indemnification under this Agreement. The indemnifying party
shall not be obligated to indemnify the indemnified party with respect to any
Claim if the indemnified party knowingly failed to notify the indemnifying party
thereof in accordance with the provisions of this Agreement in sufficient time
to permit the indemnifying party or its counsel to defend against such matter
and to make a timely response thereto including, without limitation, any
responsive motion or answer to a complaint, petition, notice or other legal,
equitable or administrative process

                                    -42-

<PAGE>



relating to the Claim, only insofar as such knowing failure to notify the
indemnifying party has actually resulted in prejudice or damage to the
indemnifying party.

    10.4 RIGHT TO CONTEST AND DEFEND. The indemnifying party shall be entitled
at its cost and expense to contest and defend by all appropriate legal
proceedings any Claim with respect to which it is called upon to indemnify the
indemnified party under the provisions of this Agreement; provided, that notice
of the intention so to contest shall be delivered by the indemnifying party to
the indemnified party within 20 days from the date of receipt by the
indemnifying party of notice by the indemnified party of the assertion of the
Claim. Any such contest may be conducted in the name and on behalf of the
indemnifying party or the indemnified party as may be appropriate. Such contest
shall be conducted by reputable counsel employed by the indemnifying party, but
the indemnified party shall have the right but not the obligation to participate
in such proceedings and to be represented by counsel of its own choosing at its
sole cost and expense. The indemnifying party shall have full authority to
determine all action to be taken with respect thereto; provided, however, that
the indemnifying party will not have the authority to subject the indemnified
party to any obligation whatsoever, other than the performance of purely
ministerial tasks or obligations not involving material expense. If the
indemnifying party does not elect to contest any such Claim, the indemnifying
party shall be bound by the result obtained with respect thereto by the
indemnified party. At any time after the commencement of the defense of any
Claim, the indemnifying party may request the indemnified party to agree in
writing to the abandonment of such contest or to the payment or compromise by
the indemnified party of the asserted Claim, whereupon such action shall be
taken unless the indemnified party determines that the contest should be
continued, and so notifies the indemnifying party in writing within 15 days of
such request from the indemnifying party. If the indemnified party determines
that the contest should be continued, the indemnifying party shall be liable
hereunder only to the extent of the amount that the other party to the contested
Claim had agreed unconditionally to accept in payment or compromise as of the
time the indemnifying party made its request therefor to the indemnified party.

    10.5 COOPERATION. If requested by the indemnifying party, the indemnified
party agrees to cooperate with the indemnifying party and its counsel in
contesting any Claim that the indemnifying party elects to contest or, if
appropriate, in making any counterclaim against the person asserting the Claim,
or any cross-complaint against any person, and the indemnifying party will
reimburse the indemnified party for any expenses incurred by it in so
cooperating. At no cost or expense to the indemnified party, the indemnifying
party shall cooperate with the indemnified party and its counsel in contesting
any Claim.

      10.6 RIGHT TO PARTICIPATE. The indemnified party agrees to afford the
indemnifying party and its counsel the opportunity to be present at, and to
participate in, conferences with all persons,

                                    -43-

<PAGE>



including governmental authorities, asserting any Claim against the indemnified
party or conferences with representatives of or counsel for such persons.

    10.7 PAYMENT OF DAMAGES. The indemnifying party shall pay to the indemnified
party in immediately available funds any amounts to which the indemnified party
may become entitled by reason of the provisions of this Agreement, such payment
to be made within five days after any such amounts are finally determined either
by mutual agreement of the parties hereto or pursuant to the final
non-appealable judgment of a court of competent jurisdiction. In calculating any
amount to be paid by an indemnifying party by reason of the provisions of this
Agreement, the amount shall be reduced by all tax benefits and other
reimbursements credited to or received by the other party related to the
Damages.

    10.8 LIMITATIONS ON INDEMNIFICATION. The Selling Stockholders and the
Purchaser shall not be liable for Damages under Section 10.2 or 10.1,
respectively, unless the aggregate amount of Damages for which the indemnifying
party would, but for the provisions of this Section 10.8, be liable exceeds, on
an aggregate basis, $50,000 at which time the indemnifying party's
indemnification obligation shall be for the entire amount in excess of $50,000;
provided, however, that such $50,000 threshold amount shall not limit any
party's liability for a knowing and intended breach of a representation,
warranty or covenant of such party hereunder. In addition, the liability of each
of the Selling Stockholders for the breach of its representations, warranties,
covenants and agreements hereunder shall be limited to the Selling Stockholder's
portion of the first $2,500,000 of the total of the Cash Consideration and
Prepayment received by such Selling Stockholder under this Agreement determined
on the basis of the Seller Percentages, respectfully, of the Selling

Agreement shall be limited to such Selling Stockholder's portion of the total
Cash Consideration and Prepayment paid by the Purchaser less any other
indemnification payments that do not relate to Section 4.10. The liability of
the Purchaser for breach of its representations, warranties, covenants and

                                  ARTICLE XI
                                   MEDIATION

    11.1 DIRECT NEGOTIATION. Notwithstanding any other provisions of this
Agreement, the parties to this Agreement (for purposes of this Article XI, the
"Party" or "Parties") agree to the prompt and equitable settlement of all
controversies or claims (a "dispute") between or among the Parties only (and not
involving third parties) including but not limited to those arising out of or
relating to this Agreement or any related agreements or instruments ("Subject
Documents"), including any claim

                                    -44-

<PAGE>



based on or arising from an alleged tort, through either negotiation, mediation
or binding arbitration as set forth in this Article XI. The Parties agree to
negotiate their differences directly and in good faith for a period of no less
than thirty days after receiving written notification of the existence of a
dispute.

    11.2 MEDIATOR. If a dispute involving only parties to this Agreement is not
resolved within thirty days after written notification of the existence of a
dispute, the Parties agree to submit their dispute to a mediator to work with
them to resolve their differences. The Parties hereto agree that at any time a
dispute is to be mediated under this Agreement, the Parties will either agree
upon a mediator to mediate the dispute or pick one in a blind drawing from a
list of names of experienced mediators compiled by each Party submitting one
such name, and the mediator whose name is drawn will mediate the dispute. The
Parties shall notify the selected mediator in writing of the existence of a
dispute and the selected mediator shall have thirty days from receipt of the
notification to meet with the Parties in an effort to help them resolve the
dispute, unless the Parties mutually consent to an extension of such deadline.
If the originally selected mediator is unable or unwilling to begin or continue
to act as the selected mediator, or if the Parties mutually agree to replace the
original or any subsequently selected mediator, a successor mediator shall be
selected by mutual agreement in the manner set forth above or, if the Parties
agree, by another method. If the Parties are unable to agree on a successor
mediator, the chief judge of the federal district courts for the Southern
District of Texas, Houston Division, shall select a mediator who may be rejected
by the Parties only for bias.

      11.3 MEDIATION PROCEDURE. The mediation shall be conducted pursuant to the
rules generally used by the mediator in the mediator's practice, subject to the
following:

          (a) The mediator shall act as an advocate for resolution and shall use
his or her best efforts to assist the Parties in reaching a mutually acceptable
settlement. The mediator may suggest ways of resolving the dispute, but may not
impose his or her own judgment on the issues and that of the Parties. The
mediator shall not have the authority to decide any issue for the Parties, but
will attempt to facilitate the voluntary resolution of the dispute by the
Parties.

          (b) Each Party participating in the mediation shall have authority to
settle, and all persons necessary to the decision to settle shall be present
during the entire mediation session or sessions.

          (c) The mediation shall take place at a time and convenient location
agreeable to the mediator and the Parties, as the mediator shall determine.


                                    -45-

<PAGE>



          (d) Mediation sessions shall be private, and only the Parties and
their representatives may attend the mediation sessions. Other persons may
attend the mediation sessions only with the written permission of the Parties
and with the consent of the mediator.

          (e) There shall be no stenographic record of the mediation process,
and no person shall tape record any portion of the mediation sessions.

          (f) No subpoenas, summons, complaints, citations, writs, or other
process may be served at or away from the site of any mediation session upon any
person who then is entering, on the way to, in attendance at or leaving the
session.

          (g) The Parties shall participate in the mediation proceeding in good
faith with the intention to settle, if at all possible.

          (h) No later than three business days prior to the mediation, each
Party shall deliver to the mediator all information reasonably required for the
mediator to understand the issues presented and a confidential memorandum (not
to exceed five pages with normal type size and margins) setting forth the
following:

    (i)   identification of the matters in dispute;

    (ii)  concise statement of points (factual, legal, practical) that each
          Party believes enhances its chance of achieving a favorable outcome of
          the dispute; and

    (iii) history of settlement discussions and outstanding offers of settlement

The above rules may be amended with the consent of the Parties.

    11.4 RELEASE. The mediator shall not be a necessary or proper Party in
judicial proceedings relating to the mediation. Neither the mediator, the firm
employing the mediator, nor the organization providing the mediator shall be
liable to any Party for any acts or omissions in connection with any mediation
conducted pursuant to this Article XI.

    11.5 COMPROMISE NEGOTIATION. The mediation is a compromise negotiation for
purposes of Rule 408 of the Federal Rules of Evidence and Texas Rules of
Evidence and is an alternative dispute resolution procedure subject to Section
154.073 of the Texas Civil Practice & Remedies Code. The entire procedure is
confidential. All conduct, statements, promises, offers, views, and opinions,
whether oral or written, made in the course of the mediation by any of the
Parties, their agents, employees, or other representatives and by the mediator,
who is the Parties' joint agent for purposes

                                    -46-

<PAGE>



of these compromise negotiations, are confidential and shall, in addition where
appropriate, be deemed to be work product and privileged. Such conduct,
statements, promises, offers, views, and opinions shall not be discoverable or
admissible for any purposes, including impeachment, in any litigation or other
proceedings involving the Parties and shall not be disclosed to anyone not an
agent, employee, expert, or other representative for any of the Parties.
Evidence otherwise discoverable or admissible is not excluded from discovery or
admission as a result of its use in the mediation. Confidential information
disclosed to the mediator by the Parties or by witnesses in the course of the
mediation shall not be divulged by the mediator. All records, reports, or other
documents received by the mediator while serving in that capacity shall be
confidential. The mediator shall not be compelled to divulge such records or to
testify with regard to the mediation in any adversarial proceeding or judicial
forum.

    11.6 COSTS OF MEDIATION. The Parties shall bear their respective costs
incurred in connection with the mediation described in this Article XI, except
that the Parties shall share equally the fees and expenses of the mediator, the
costs of obtaining the facility for the mediation, and the fees and expenses of
any experts employed at the request of the mediator.

      11.7 TERMINATION OF MEDIATION. The mediation shall be terminated upon the
first to occur of the following:

          (a) the execution of a settlement agreement resolving the dispute by
the Parties;

          (b) a written declaration of the mediator to the effect that further
efforts at mediation are no longer worthwhile; or

          (c) after the completion of two full days of mediation sessions, by
written declaration of a Party or Parties to the effect that mediation
proceedings are terminated.

    11.8 MANDATORY BINDING ARBITRATION. In the event that such dispute is not
resolved through mediation as described above, then the Parties agree that such
dispute shall be determined by binding arbitration in accordance with the Texas
General Arbitration Act and the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"). All statutes of limitations which would
otherwise be applicable shall apply to any arbitration proceeding under this
Section 11.8. Judgment upon the award rendered in such arbitration proceeding
may be entered in any court having jurisdiction. This section shall apply only
if, at the time of proposed submission to AAA, the Parties have first tried to
resolve such dispute through a non-binding mediation as provided above or have
mutually agreed in writing to waive the right to resolve such dispute through
mediation.

    11.9 INJUNCTIVE RELIEF. Notwithstanding any other provision of this
Agreement or this Article XI to the contrary, no Party hereto shall be precluded
from seeking injunctive relief or a temporary restraining order prior to
implementing procedures for mediation or arbitration hereunder provided that
such Party determines in the good faith exercise of its best judgment that any
Party hereto or the Company will suffer irreparable injury or harm by any delay
caused by mediation or arbitration proceedings.


                                  ARTICLE XII
