        Buyer and to be paid to the Seller on the thirtieth (30th) day following
        the end of the Earn Out Period. If Seller objects to the calculation of
        the Earn Out, it shall notify Buyer within twenty (20) days following
        receipt thereof, setting forth in specific detail the basis for its
        objection and its proposal for any adjustments to the Earn Out. Buyer
        and Seller shall undertake in good faith to reach agreement as to any
        such proposed adjustment or that no such adjustment is necessary. If
        agreement is reached as to all proposed further adjustments, the parties
        shall make such adjustments and the Earn Out shall be based thereon. If
        Buyer and Seller are unable to reach agreement within thirty (30) days,
        then such "Big 6" accounting firm as agreed upon by Buyer and Seller
        (the "THIRD PARTY ACCOUNTING FIRM") shall be engaged to review the
        proposed adjustments as to which agreement has not been reached and
        shall make a determination as to the resolution of the proposed
        adjustments to cause the Earn Out to have been properly calculated in
        accordance with the provisions of this Agreement. All such resolutions
        shall relate only to such matters as are still in dispute and were
        properly included in the notice of Seller's objection and represent
        either agreement with the position taken by Seller or by Buyer or a
        compromise between such positions. The determination of the Third Party
        Accounting Firm shall be final, conclusive and binding upon Buyer and
        Seller. Thereafter, not later than ten (10) days following a
        determination of adjustments by the Third Party Accounting Firm, Buyer
        shall pay to Seller an amount in cash equal to the additional Earn Out,
        if any, as determined by the Third Party Accounting Firm. Buyer and
        Seller shall share equally the costs of the Third Party Accounting Firm
        under this Section 1.1(b)(iv).

        1.2       POST-CLOSING ADJUSTMENT.

                  (a) Subsequent to the Closing (as defined below), Seller shall
prepare a balance sheet of the Company at the close of business on the Closing
Date (the "CLOSING BALANCE SHEET"). The Closing Balance Sheet shall be prepared
in accordance with generally accepted accounting principles ("GAAP") used by the
Company for financial reporting to Seller consistently applied. Based on the
Closing Balance Sheet, Seller shall calculate (i) the total value of the
accounts receivable, cost and related earnings in excess of billings and
inventory (which shall not be written down below net realizable value) of the
Company as of the Closing Date (the "CLOSING VALUE"), which for purposes hereof
shall exclude any cash and intercompany accounts and (ii) the post- Closing
adjustment, which shall be the difference between the Closing Value and the
Adjustment Amount (the "POST-CLOSING ADJUSTMENT"). Upon completion of the same,
but not later than thirty (30) days after the Closing Date, Seller shall deliver
a copy of the Closing Balance Sheet and the calculations of the Closing Value
and the Post-Closing Adjustment to Buyer.

                  (b) If the Closing Value exceeds the Adjustment Amount, Buyer
shall owe the Post-Closing Adjustment to Seller. If the Closing Value is less
than the Adjustment Amount, the $4,000,000 amount set forth in Section
1.1(b)(iv) above shall be reduced by the Post-Closing Adjustment and, to the
extent the Post-Closing Adjustment exceeds $4,000,000, the balance shall be
treated as a payment of principal on the Note. If Buyer does not object to the
amount of the Post-Closing Adjustment within twenty (20) days of receipt
thereof, (i) Buyer shall pay to Seller, no later than the second Business Day
after the twentieth day following receipt of the Post-Closing Adjustment, an
amount in cash equal to the Post-Closing Adjustment owed by Buyer to Seller or
(ii) the $4,000,000 amount set forth in Section 1.1(b)(iv) above shall be
reduced by the Post-Closing Adjustment.

                  (c) If Buyer objects to the Post-Closing Adjustment, it shall
notify Seller within twenty (20) days following receipt thereof, setting forth
in specific detail the basis for its objection and its proposal for any
adjustments to the Post-Closing Adjustment. Buyer and Seller shall undertake in
good faith to reach agreement as to any such proposed adjustment or that no such
adjustment is necessary. If agreement is reached as to all proposed further
adjustments, the parties shall make such adjustments and the Post-Closing
Adjustment shall be based thereon. If Buyer and Seller are unable to reach
agreement within thirty (30) days, then a Third Party Accounting Firm shall be
engaged to review the proposed adjustments as to which agreement has not been
reached and shall make a determination as to the resolution of the proposed
adjustments to cause the Post-Closing Adjustment to have been properly prepared
in accordance with the provisions of this Agreement. All such resolutions shall
relate only to such matters as are still in dispute and were properly included
in the notice of Buyer's objection and represent either agreement with the
position taken by Seller or by Buyer or a compromise between such positions. The
determination of the Third Party Accounting Firm shall be final, conclusive and
binding upon Buyer and Seller. Thereafter, not later than ten (10) days
following a determination of adjustments by the Third Party Accounting Firm,
either Buyer shall pay to Seller an amount in cash equal to the Post-Closing
Adjustment, as determined by the Third Party Accounting Firm, or the $4,000,000
amount set forth

                                             -3-
<PAGE>
in Section 1.1(b)(iv) above shall be reduced by the Post-Closing Adjustment, as
determined by the Third Party Accounting Firm. Buyer and Seller shall share
equally the costs of the Third Party Accounting Firm under this Section 1.2(c).

        2.4       INITIAL FINANCIAL STATEMENTS; ACCOUNTING AND OTHER SYSTEMS; 
                  DISCLOSURE.

                  (a) SCHEDULE 2.4(A) contains a copy of the unaudited balance
sheet of the Company as of December 31, 1997 and the related statements of
income and stockholder's equity and cash flow statements for such period (the
"INITIAL FINANCIAL STATEMENTS"). The Initial Financial Statements fairly present
the financial position of the Company and the results of operations as of the
indicated date and for the indicated period and have been prepared in accordance
with GAAP consistently applied, excluding any footnotes and have been prepared
consistent with the preparation of Seller's audited financial statements.

                  (b) The Company had no outstanding Indebtedness to any Person
or any liabilities of any kind (including contingent obligations, tax
assessments or unusual forward or

                                             -5-
<PAGE>
long-term commitments), or any unrealized or anticipated loss, which in the
aggregate then were Material to the Company and required to be reflected in the
Initial Financial Statements in accordance with GAAP which were not so
reflected.

                  (c) Copies of all material financial reports prepared by the
Company or the Seller for management of the Company since December 31, 1997 have
been provided to Buyer. Since December 31, 1997, no change has occurred in the
business, operations, properties or assets, liabilities, condition (financial or
other) or results of operations of the Company that has or could reasonably be
expected, either alone or together with all other such changes, to have a
Material Adverse Effect. A true and correct listing of all open orders equal to
or greater than $50,000 for products and services received by the Company has
been provided to Buyer.

                  (d) The Company maintains a system of internal accounting
controls sufficient to provide reasonable assurances that (i) transactions are

statements in conformity with GAAP and to maintain accountability for assets,
(iii) access to assets is permitted only in accordance with management's general
or specific authorization and (iv) the recorded accountability for cash,

intervals and appropriate action is taken with respect to any differences. The
Company records a fixed asset at cost at the time of its acquisition and removes
a fixed asset upon its sale or transfer if the fixed asset had a positive net
book value at the time of the sale or transfer. The Company recently has made a
series of entries to the fixed asset subsidiary ledger removing certain assets,
the original cost of such assets and the accumulated depreciation of such assets
from the fixed asset subsidiary ledger; such assets were fully depreciated,
without salvage value and having an original cost of less than $1,500.
Corresponding adjustments were made to the general ledger, the fixed asset
original cost control account and the fixed asset accumulated depreciation
account. The Company is in the process of converting its accounting software and
other business application systems to the Enterprise Resource Planning system
("ERP"). The ERP system is currently fully and, to the knowledge of Seller,
successfully operated at Halter Marine (including the basic accounting
functions). The ERP system is currently fully operational at the Company for the
purpose of performing labor reporting, and within the next six (6) to eight (8)
months is scheduled to be fully operational on all remaining modules including
scheduling and shop floor control, engineering computer assisted design/bill of
material, purchasing material requirement orders/bill of material and accounting
functions. All necessary hardware and software is owned, leased or licensed and
installed, and completion of implementation is primarily dependent on
preparation of manuals, documentation and training of personnel. Seller makes no
representation or warranty as to the performance or adequacy of the ERP system.

                  (e) Set forth in SCHEDULE 2.4 is a list of all computer
software programs owned by the Company (the "OWNED SOFTWARE"). Set forth in
SCHEDULE 2.4 is a list of all computer software programs licensed by the

Licensed Software are sufficient to conduct the business and operations of the
Company as presently being conducted.

the current business of the Company. Except as referred to in SCHEDULE 2.12,
there is not in existence at present any Governmental Requirement enjoining or
requiring the Company or Seller to take any action of any kind with respect to
the Company (excluding Governmental Requirements not specifically directed to or
at Seller or the Company).

                  (d) Notwithstanding the language of Section 2.12(a), (b) and

pursuant thereto are exempt from federal income taxation under Section 501 of
the Code. To the best knowledge of Seller as of the date hereof, nothing has
occurred or failed to occur with respect to the operation or the form of such

Related Party Agreements are materially no less favorable to the Company than
the Company reasonably could have expected to obtain in an arm's-length
transaction with a Person other than an affiliate of the Company, the

                                             -21-

Subject Property and their contents, any analyses, compilations, studies or
other documents prepared by Buyer, its affiliates or its Consultant containing

connection with the transaction contemplated by this Agreement. Buyer agrees
that the Inspection shall be conducted in strict compliance with the following:

permitted by this Section 4.6 and, except as otherwise permitted by this Section
4.6 or required by law, Buyer shall not disclose the Environmental Information
to any third party other than the Persons requested to provide financing to, or
investment in, Buyer (and their respective legal counsel and other professional
counsel) with respect to the transactions contemplated hereby and its
representatives and agents that are directly involved in the transaction
contemplated by this Agreement; (iv) Buyer shall be responsible for any breach
of this Section 4.6 by the Consultant, Buyer's representatives or any third
party to whom Buyer transmits the Environmental Information; (v) if the
transactions contemplated by this Agreement are not consummated for any reason,
all Environmental Information, including all copies of any Consultant's reports
and test results, if any, in written or other recorded form shall be delivered
to Seller and Buyer shall not retain any copies; (vi) in the event that Buyer or
anyone to whom Buyer transmits the Environmental Information becomes legally
compelled to disclose any of the Environmental Information, and if Buyer becomes
aware of such potential disclosure, Buyer shall provide Seller with prompt
notice prior to any such disclosure so that Seller may seek a protective order
or other appropriate remedy and/or waive compliance with any applicable
provisions of this Section 4.6; (vii) unless legally compelled to do so, prior
to the Closing Date Buyer shall not disclose any Environmental Information to
any regulatory agencies concerning the Subject Property, without the express
prior written consent of Seller, such consent not to be unreasonably withheld or
delayed; provided, however, that Seller understands and agrees that Buyer or its
representatives may find it appropriate to contact Governmental Authorities in

hereby consents to and authorizes such contact; (viii) Buyer shall promptly
disclose and provide copies to Seller (at no cost to Buyer) all Environmental

the Inspection, which to be approved must conform to the following requirements:

                                      COVENANTS OF BUYER

        Buyer hereby covenants and agrees with Seller as follows:

        5.1 RETENTION OF RECORDS. Buyer shall, for a period of seven (7) years
after the Closing Date, neither dispose of nor destroy any of the business
records and files of the Company which are transferred in connection herewith
without first offering to turn over possession thereof to Seller by written
notice to Seller at least sixty (60) days prior to the proposed date of such
disposition or destruction.

        5.2 APPROVALS AND CONSENTS. Buyer shall use all commercially reasonable
efforts (a) to cause all conditions to the obligations of Seller under this
Agreement over which it is able to exercise influence or control to be satisfied
prior to the Closing Date and (b) to obtain promptly and to comply with all
requisite statutory, regulatory or court approvals, third party releases and
consents, and other requirements necessary for the valid and legal consummation
of the transactions contemplated hereby.

        5.3 MATTERS PERTAINING TO EMPLOYMENT. Pursuant to Article VIII hereof,
Buyer shall indemnify and hold harmless Seller from any liability that Seller
incurs under the Worker Adjustment and Retraining Notification Act or similar
state laws which results from the Company failing to offer employment to
employees of Seller or the Company that devote substantially all of their
working time to the business operations of the Company (the "BEAIRD EMPLOYEES")
or reducing the workforce by such number that results in liability. Seller shall
provide all Beaird Employees terminated by Seller with health insurance
continuation to the extent required by COBRA.

        5.4 COURSE OF CONDUCT BY THE COMPANY. From the Closing Date through and
until the date Seller receives cash payment of the Earn Out, except as approved
in writing by Seller or as otherwise expressly permitted or contemplated by this
Agreement, Buyer shall cause the Company's business to be conducted only in the
ordinary course of business consistent with past practice, including, without
limitation the Company's maintenance of the same GAAP as utilized by Seller
before the Closing Date. During the period set forth in the preceding sentence,
(i) Seller shall have appropriate rights to review, monitor and comment on the
operations of the Company and the results thereof, (ii) Buyer shall provide
Seller and its representatives and agents such access to the books and records
of the Company and furnish to Seller such financial and operating data and other
information with respect to the business and property of the Company as it may
reasonably request from time to time, and permit Seller and its respective
representatives and agents to make such inspections of the Company's real and
personal properties as they may reasonably request with regard to the
determination of the Earn Out and (iii) if Buyer desires to operate in a manner
that is different from the standard set forth in the preceding sentence, then
Buyer and Seller shall undertake in good faith to reach agreement as to the
adjustment, if any, in the calculation of the Earn Out in Section 1.1(b)(iv)
above to compensate Seller for the financial impact of the proposed different
manner of operation. If agreement is reached as to the adjustment, if any, in
the calculation of the

                                             -30-
<PAGE>
Earn Out, then the language of Section 1.1(b)(iv) above shall be so amended and
the Earn Out shall be based thereon. If Buyer and Seller are unable to reach
agreement within thirty (30) days, then a Third Party Accounting Firm shall be
engaged to review the proposed change in operation and shall make a
determination as to the adjustment, if any, in the calculation of the Earn Out
in Section 1.1(b)(iv) to compensate Seller for the financial impact of the
proposed different manner of operation. The determination of the Third Party
Accounting Firm shall be final, conclusive and binding upon Buyer and Seller.
Buyer and Seller shall share equally the costs of the Third Party Accounting
Firm under this Section 5.4.

        5.5 OFCCP AUDIT. Buyer agrees that Seller shall manage the pending audit
by the Office of Federal Contract Compliance Program, provided that the
resolution of any matters affecting the operation of the Company after Closing
shall require the consent of Buyer, such consent not to be unreasonably
withheld.

guaranties and bonds so as to allow Seller and its affiliates to be released
from any and all liability relating to any guaranties or bonds issued to secure
an agreement, obligation or liability of the Company, all of which are described
on SCHEDULE 2.25.

        determines that, together with any liability identified pursuant to
        Section 7.1(a)(v), a contingent or actual liability in excess of
        $1,000,000 potentially exists as a result of such failure.

contemplated by this Agreement. Buyer shall have no right to claim or seek from
Seller any other damages, costs or expenses arising out of a failure to close
the transactions contemplated by this Agreement.

the one hand, and Buyer, on the other hand, shall give prompt written notice (a
"SPECIAL NOTICE") to the other after it has obtained knowledge of the
occurrence, or failure of occurrence, of any event, which occurrence or failure
to occur would cause or be reasonably likely to cause a breach of their
respective representations, warranties, covenants and agreements contained in
this Agreement.

                  (b) If Buyer gives such Special Notice and Seller fails to

and warranties identified in Section 8.2(a)(v), for purposes of this Article
VIII, shall be read as if they contained no qualification for Material Adverse
Effect) being untrue or incorrect in any material respect; (ii) any failure by
Seller to observe or perform its covenants and agreements set forth in this
Agreement in any respect; (iii) events occurring on or prior to the Closing
Date; (iv) any claim, action, or proceeding made or brought by or obligations
owed by the Company to any person formerly employed by the Company who is not so
employed as of the Closing Date whether by reason of retirement, death,
incapacity, discharge, severance or otherwise; (v) product liability, litigation
or claims against the Company or any of its directors, officers, employees,
representatives, agents or attorneys in connection with, arising out of, or
relating to products completed by the Company on or prior to the Closing Date;
and (vi) any matter identified in part (b) clause (i) of SCHEDULE 2.8, SCHEDULE
2.11, SCHEDULE 2.12, SCHEDULE 2.13 or part (b) clause (i) of SCHEDULE 2.25;
except in any instance to the extent Buyer's Losses result from a Buyer
Indemnitee's own ordinary or gross negligence or willful misconduct.

                  (b) "BUYER'S LOSSES" shall mean all (i) Damages, (ii) Damage
Claims and (iii) liabilities and obligations for any Company Indebtedness and
all other liabilities and obligations of the Company outstanding as of the
Closing Date. Buyer's Losses shall not include Environmental Costs (as defined
in Section 8.2), which are addressed in Section 8.2.

        8.2       ENVIRONMENTAL INDEMNITY.

                  (a) Seller agrees to indemnify and hold harmless Buyer and the
Company and their respective directors, officers, employees, representatives,
agents and attorneys from and against, and in respect of any and all third party
claims for, Environmental Costs arising in any manner in connection with: (i)
the presence at or on any property now or formerly owned, operated or leased by
the Company at any time on or prior to the Closing Date of any Hazardous
Substances or the release, leak, discharge, spill, disposal, migration or
emission of Hazardous Substances from

                                             -37-
<PAGE>
any such property on or prior to the Closing Date; (ii) the failure of the
Company to comply with any applicable Environmental Requirements prior to the
Closing Date; (iii) the transportation to, disposal at, or migration onto or
into adjacent property or any off-site location of any Hazardous Substances from
property now or formerly owned, operated or leased by the Company at any time on
or prior to the Closing Date, whether or not the transportation or disposal was
conducted in full compliance with Environmental Requirements; (iv) any matter
identified in SCHEDULE 2.7, (v) any representation or warranty made by Seller
which relates expressly or by necessary implication to the Identified
Remediation, the environment or Environmental Requirements (which, for purposes
of this Article VIII, shall be read as if they contained no qualification for
Material Adverse Effect) being untrue or incorrect in any material respect, or
(vi) any failure by Seller to observe or perform its covenants set forth in
Sections 8.9, 8.10, 8.11 or 8.12 in any respect. Without limitation of the
foregoing, it is hereby recognized and agreed that all Environmental Costs or
other costs and expenses of the Identified Remediation shall be paid by the
Seller, including, without limitation, the charges of such consulting engineer,
all power and utility costs, all capital expenditures and any and all taxes or
fees that may be applicable to such activities. None of the Environmental Costs
or other costs and expenses paid or incurred by the Seller in connection with
the Identified Remediation shall (i) be subject to reimbursement from either the
Company or Buyer or (ii) be reflected as an asset on the Closing Balance Sheet
on the Initial Financial Statements.

                  (b) The obligations under this Section 8.2 shall include the
obligation to defend the Indemnified Parties (as defined below) against any
claim or demand for Environmental Costs, the obligation to pay and discharge any
Environmental Costs imposed on the Indemnified Parties, and the obligation to
reimburse the Indemnified Parties for any Environmental Costs incurred or
suffered, provided in each instance that the claim for Environmental Costs
arises in connection with a matter for which Indemnified Parties are entitled to
indemnification under this Agreement. The obligation to reimburse the
Indemnified Parties shall also include the costs and expenses (including,
without limitation, reasonable attorneys' fees) to establish or enforce Buyer's
or such other Person's right to indemnification hereunder, but shall exclude
reimbursement to the extent Environmental Costs result from a Buyer Indemnitee's
own ordinary or gross negligence or willful misconduct.

                  (c) "ENVIRONMENTAL COSTS" shall mean any of the following that
arise in any manner regardless of whether based in contract, common law, tort,
implied or express warranty, strict liability, Environmental Requirement or
otherwise: all liabilities, losses, judgments, damages, punitive damages, treble
damages, natural resource damages, costs and expenses (including, without
limitation, reasonable attorneys' fees and fees and disbursements of
environmental consultants, all costs related to the performance of any required
or necessary assessments, investigations, remediation, response, containment,
closure, restoration, repair, cleanup or detoxification of any impacted
property, the preparation and implementation of any maintenance, monitoring,
closure, remediation, abatement or other plans required by any governmental
agency or by Environmental Requirements and any other costs recovered or
recoverable under any Environmental Requirement), fines, penalties, or monetary
sanctions. Environmental Costs shall not (except in connection with a
Third-Party Claim) include (i) loss of earnings or profits attributable to the
consequential loss of future business or contracts or (ii) business interruption
losses, together with business interruption

                                             -38-
<PAGE>
losses subject to Section 8.1, in excess of $2,500,000 in the aggregate (such
monetary limitation being intended to qualify clause (ii) only).

        8.3       SELLER'S LOSSES.

                  (a) From and after the Closing Date, subject to the other
provisions of this Article VIII, Buyer agrees to indemnify and hold harmless
Seller and its directors, officers, employees, representatives, agents and
attorneys ("SELLER INDEMNITEES") from, against, for and in respect of any and
all Seller's Losses (as defined below) suffered, sustained, incurred or required
to be paid by Seller by reason of (i) any representation or warranty made by
Buyer in Article III of this Agreement being untrue or incorrect in any material
respect; (ii) any failure by Buyer to observe or perform its covenants and
agreements set forth in this Agreement in any respect; or (iii) product
liability, litigation or claims against Seller or any of its directors,
officers, employees, representatives, agents or attorneys in connection with,
arising out of, or relating to products completed by the Company from and after
the Closing Date; except in any instance to the extent Seller's Losses result
from a Seller Indemnitee's own ordinary or gross negligence or willful
misconduct.

                  (b) "SELLER'S LOSSES" shall mean all Damages and Damage
Claims.

        8.4 NOTICE OF LOSS. An Indemnified Party claiming indemnification under
this Agreement shall promptly (i) notify the party from whom indemnification is
sought (the "INDEMNIFYING PARTY") of any third party claim or claims asserted
against the Indemnified Party ("THIRD PARTY CLAIM") that could give rise to a
right of indemnification under this Agreement and (ii) transmit to the
Indemnifying Party a written notice ("CLAIM NOTICE") describing in reasonable
detail the nature of the Third Party Claim, a copy of all papers served with
respect to that claim (if any), an estimate of the amount of damages
attributable to the Third Party Claim to the extent feasible (which estimate
shall not be conclusive of the final amount of that claim) and the basis for the
Indemnified Party's request for indemnification under this Agreement.
Notwithstanding the preceding sentence, failure of the Indemnified Party to give
notice hereunder shall not release the Indemnifying Party from its obligations
under this Article VIII, except to the extent the Indemnifying Party is actually
prejudiced by such failure to give notice. Within fifteen (15) days after
receipt of any Claim Notice (the "ELECTION PERIOD"), the Indemnifying Party
shall notify the Indemnified Party (i) whether the Indemnifying Party disputes
its potential liability to the Indemnified Party under this Article VIII with
respect to that Third Party Claim and (ii) if the Indemnifying Party does not
dispute its potential liability to the Indemnified Party with respect to that
Third Party Claim, whether the Indemnifying Party desires, at the sole cost and
expense of the Indemnifying Party, to defend the Indemnified Party against that
Third Party Claim. With respect to Buyer's Losses and Environmental Costs,
Seller shall be the "INDEMNIFYING PARTY" and Buyer and the Company and its
respective directors, officers, employees, representatives, agents and attorneys
shall be the "INDEMNIFIED PARTIES." With respect to Seller's Losses, Buyer shall
be the "INDEMNIFYING PARTY" and Seller and its directors, officers, employees,
representatives, agents and attorneys shall be the "INDEMNIFIED PARTY."

                                             -39-
<PAGE>
        8.5       RIGHT TO DEFEND.

                  (a) If the Indemnifying Party does not dispute its potential
liability to the Indemnified Party and notifies the Indemnified Party within the
Election Period that the Indemnifying Party elects to assume the defense of the
Third Party Claim, then the Indemnifying Party shall be entitled to defend,
contest or otherwise protect against any such Third Party Claim at its sole cost
and expense, and the Indemnified Party must cooperate in any such defense or
other action.

                  (b) The Indemnified Party shall have the right, but not the
obligation, to participate at its own expense in defense or settlement thereof
by counsel of its own choosing, but the Indemnifying Party shall be entitled to
control the defense unless the Indemnified Party has relieved the Indemnifying
Party from liability with respect to the particular matter or the Indemnifying
Party fails to assume defense of the matter; PROVIDED, HOWEVER, (i) that the
Indemnifying Party shall not enter into any settlement with respect to any Third
Party Claim that purports to limit the activities of, or otherwise restrict in
any way, any Indemnified Party without the prior consent of that Indemnified
Party (which consent may be withheld in the sole discretion of that Indemnified
Party) and (ii) if the named parties to any such action (including any impleaded
parties) include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised in writing by its counsel that there may be
one or more legal defenses available to it which are different from or
additional to those available to the Indemnifying Party, and a copy of any such
written advice is provided to the Indemnifying Party, then the Indemnified Party
may employ separate counsel at the expense of the Indemnifying Party, and, on
its written notification of that employment, the Indemnifying Party shall not
have the right to assume or continue the defense of such action on behalf of the
Indemnified Party.

                  (c) If the Indemnifying Party (i) within the Election Period
(A) disputes its potential liability to the Indemnified Party under this Article
VIII, (B) elects not to defend the Indemnified Party pursuant to this Article
VIII or (C) fails to notify the Indemnified Party that the Indemnifying Party
elects to defend the Indemnified Party pursuant to this Article VIII or (ii)
elects to defend the Indemnified Party pursuant to this Article VIII but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right, but not the obligation, thereafter to
defend, contest or otherwise protect against the same and make any compromise or
settlement thereof and recover the entire cost thereof from the Indemnifying
Party including, without limitation, reasonable attorneys' fees, disbursements
and all amounts paid as a result of such suit, action, investigation, claim or
proceeding or the compromise or settlement thereof. The Indemnified Party shall
have full control of such defense and proceedings. Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes its
potential liability to the Indemnified Party under this Article VIII and if that
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to indemnify the Indemnified Party for any Damages or
Damage Claims that would otherwise be deemed to be an Indemnified Loss, or to
bear the costs and expenses of the Indemnified Party's defense pursuant to this
Section 8.5 or of the

                                             -40-
<PAGE>
Indemnifying Party's participation therein at the Indemnified Party's request,
and the Indemnified Party shall reimburse the Indemnifying Party in full for all
reasonable costs and expenses incurred by the Indemnifying Party in connection
with any such participation and any litigation or other proceeding relating to
the resolution of any such dispute. The Indemnifying Party may participate in,
but not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 8.5(c), and the Indemnifying Party shall bear its own
costs and expenses with respect to that participation.

                  (d) In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "INDEMNITY NOTICE") describing in reasonable detail the nature of
the claim, an estimate of the amount of Damages attributable to that claim to
the extent feasible (which estimate shall not be conclusive of the final amount
of that claim) and the basis of the Indemnified Party's request for
indemnification under this Agreement. If the Indemnifying Party does not notify
the Indemnified Party in writing within thirty (30) days from its receipt of the
Indemnity Notice that the Indemnifying Party disputes the claim specified by the
Indemnified Party in the Indemnity Notice, that claim shall be deemed a
liability of the Indemnifying Party hereunder. If the Indemnifying Party has
timely disputed that claim, as provided above, that dispute shall be resolved
through litigation; provided, that upon either party receiving an Indemnity
Notice, but prior to a party initiating litigation against the other party
(unless such initiation is required to prevent the expiration of the applicable
survival periods set forth in Section 10.10), Buyer and Seller agree to cause
their respective senior managements to meet to attempt in good faith to reach a
settlement on the disputed claim. If the parties do not reach a settlement of
that dispute within thirty (30) days after notice of that dispute is given, the
parties may proceed to litigation.

                  (e) Payments of all amounts owing by an Indemnifying Party
pursuant to this Article VIII relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of that Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of that Third Party Claim or (iii) the expiration of the period for
appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement in respect of that Third Party Claim.
Payments of all amounts owing by an Indemnifying Party pursuant to Section
8.5(d) shall be made within thirty (30) days after the later of (i) the
expiration of the thirty (30) day Indemnity Notice period, (ii) the expiration
of the period for appeal of a final adjudication of that claim or (iii) the
expiration of the period for appeal of a final adjudication of the Indemnifying
Party's liability to the Indemnified Party under this Agreement in respect of
that claim.

        8.6 COOPERATION. Buyer and Seller shall cooperate with each other (and
Buyer shall cause the Company to cooperate) in the defense of any Third Party
Claim and, to the extent required by Section 8.11(d), in the Identified
Remediation (as defined in Section 8.9) and, during normal business hours, shall
afford each other access to their books and records and employees relating to
such suit, action, investigation, proceeding or claim and shall furnish each
other all such further

                                             -41-
<PAGE>
information that they have the right and power to furnish as may reasonably be
necessary to defend such suit, action, investigation, proceeding or claim,
including, without limitation, reports, studies, correspondence and other
documentation relating to Environmental Protection Agency, Occupational Safety
and Health Administration, and Equal Employment Opportunity Commission matters.
In the event either Buyer and the Company on the one hand or Seller on the other
hand fails to reasonably cooperate with the other party pursuant to this Section
8.6 in any suit, action, investigation, proceeding, claim or remediation, the
party's right to indemnification or remediation with respect to such matter
shall be reduced by the cost to the indemnifying party caused by such failure to
cooperate.

        8.7       LIMITATION ON INDEMNIFICATION.

                  (a) To the extent a Buyer's Loss related to a breach of a
representation, warranty or covenant by Seller as to the total value of the
accounts receivable and inventory as of the Closing Date that has been taken
into account in determining the Closing Value, Seller shall not have liability
to Buyer related to such breach to the extent of the Post-Closing Adjustment.

                  (b) Seller shall not have any liability or obligation to an
Indemnified Party under Section 8.1 and 8.2 unless and until the amount of
Buyer's Losses and Environmental Costs incurred by Buyer exceed the sum of
$390,000 in the aggregate (the "BUYER THRESHOLD AMOUNT"), whereupon Seller shall
be liable for all of Buyer's Losses and Environmental Costs only to the extent
such Buyer's Losses and Environmental Costs in the aggregate exceed the Buyer
Threshold Amount; PROVIDED HOWEVER, that the following items shall not be
subject to this Section 8.7(b): (i) any Buyer's Losses suffered, sustained,
incurred or required to be paid by reason of the items identified in Section
8.1(a)(vi), (ii) the reduction of the $4,000,000 amount set forth in Section
1.1(b)(iv) to the extent required by Section 1.2, (iii) Seller's violation of
any provision set forth in Section 4.4, 8.9, 8.10, 8.11, 8.12, 8.13, (iv)
Seller's indemnity obligations under Article IX and (v) Seller's violation of
representations and warranties hereunder, and any Buyer's Losses and
Environmental Costs, in each case which relate expressly or by necessary
implication to the Identified Remediation (but not otherwise to the environment
or Environmental Requirements).

                  (c) Buyer shall not have any liability or obligation to an
Indemnified Party under Section 8.1 unless and until the amount of Seller's
Losses incurred by Seller exceed the sum of $390,000 in the aggregate (the
"SELLER THRESHOLD AMOUNT"), whereupon Buyer shall be liable for all of Seller's
Losses only to the extent such Seller's Losses in the aggregate exceed the
Seller Threshold Amount; PROVIDED HOWEVER, that the following items shall not be
subject to this Section 8.7(c): (i) payment of the Post-Closing Adjustment in
the event Buyer owes the Post-Closing Adjustment to Seller, (ii) Buyer's
indemnity obligations under Section 5.3, (iii) Buyer's obligations under
Sections 5.4 and 5.6, (iv) Buyer's obligations under the Indemnification
Agreement delivered pursuant to Section 6.2(b)(xii), and (v) Buyer's indemnity
obligations under Article IX.

                                             -42-
<PAGE>
                  (d) In no event shall Seller's aggregate liability under this
Agreement for Buyer's Losses under Section 8.1 and Environmental Costs under
Section 8.2 or Buyer's aggregate liability under this Agreement for Seller's
Losses under Section 8.1 exceed an amount equal to the Purchase Price (as
adjusted up or down, as the case may be, by the amount of the Post-Closing
Adjustment). This limitation shall not apply to Seller's obligations under
Section 8.9 or Buyer's obligations under the Indemnification Agreement delivered
pursuant to Section 6.2(b)(xii).

        8.8 EXCLUSIVE REMEDIES. The rights of indemnification provided by this
Article VIII shall be the exclusive remedy of (a) Buyer with respect to matters
resulting in Buyer's Losses and Environmental Costs arising under or relating to
this Agreement or the transactions contemplated hereby and (b) Seller with
respect to matters resulting in Seller's Losses arising under or relating to
this Agreement or the transactions contemplated hereby; and neither Buyer nor
Seller shall have any other recourse for money damages against the other party
under equity, law, contract or any other theory of recovery such that in no
event shall any liability or obligation of Buyer or Seller exceed or extend
beyond the rights set forth in this Article VIII; PROVIDED that such rights
shall not be exclusive of any rights or remedies available to any party with
respect to equitable relief concerning the matters set forth in the
Confidentiality Agreement, the Noncompetition Agreement and Section 2.13.

        8.9 IDENTIFIED REMEDIATION COVENANT. Seller shall perform any and all
testing, sampling, response, clean-up, containment, restoration, removal,
transport or disposal of Hazardous Substances or other remedial work which is
required to be performed, whether on-site or off-site, by applicable
Environmental Requirements arising in connection with the presence of the
Hazardous Substances at the locations and at the concentration levels that are
or become the subject matter of Sellers' claims under any Litigation referred in
Section 8.12 ("IDENTIFIED REMEDIATION"). If Seller shall fail to timely
commence, or cause to be commenced, or fail to diligently prosecute to
completion, such Identified Remediation, Buyer may cause such Identified
Remediation to be performed, and all Environmental Costs or other reasonable
costs and expenses incurred in connection with the Identified Remediation, shall
be due and payable by Seller upon demand therefor by Buyer; PROVIDED, HOWEVER,
to the extent that Buyer performs Identified Remediation under this Section 8.9,
Buyer shall comply with the requirements that would otherwise be applicable to
Seller's performance of remediation under Sections 8.10 and 8.11 of this
Agreement and provided further that Buyer shall not commence Identified
Remediation prior to providing Seller with thirty (30) days written notice of
its intent to do so. The costs of any Identified Remediation performed by Buyer
prior to the expiration of this thirty (30) day period except as required by any
Governmental Authority to be performed within such thirty (30) day period shall
not be subject to reimbursement by Seller.

        8.10 CLEANUP STANDARDS. Notwithstanding any provision in this Agreement
to the contrary, the Identified Remediation performed by Seller under this
Agreement shall in all cases be performed in accordance with the requirements
necessary to achieve cleanup levels consistent with the current industrial use
of the Subject Property as allowed by the appropriate agency after reasonable
negotiation, including the use of institutional controls, such as deed
recordation rather

                                             -43-
<PAGE>
than total removal or treatment and engineering controls to the extent they do
not materially and adversely impact the then current industrial use of the
Subject Property or impose material post closure unreimbursed costs on Buyer,
provided that the use of engineering controls shall not be used without the
Buyer's prior written consent, not to be unreasonably withheld.

        8.11      PERFORMANCE OF IDENTIFIED REMEDIATION.  All Identified 
Remediation shall be performed by Seller as follows:

                  (a) All Identified Remediation shall be performed and
conducted: (i) continuously with reasonable diligence and in accordance with all
applicable Environmental Requirements; (ii) in a good, safe and workmanlike
manner and shall minimize any impact on the business conducted at the Subject
Property; (iii) pursuant to a detailed written remediation plan ("IDENTIFIED
REMEDIATION ACTION PLAN"), which shall be provided to Buyer for its review
before work is undertaken; the Identified Remediation Action Plan shall be
consistent with sound industry practices and in compliance with applicable
Environmental Requirements, and shall be approved by the appropriate
Governmental Authorities, if such approval is required by Environmental
Requirements; (iv) with such insurance coverage pertaining to liabilities
arising out of the work as is customarily maintained with respect to such
activities; and (v) only upon receipt of all required permits, licenses or
approvals from Governmental Authorities.

                  (b) Promptly upon completion of the Identified Remediation,
Seller shall permanently seal or cap all monitoring wells, test holes and other
intrusions to industrial standards in compliance with Environmental
Requirements, remove all associated equipment, and restore the Subject Property
to its condition prior to the performance of the Identified Remediation, which
shall include, without limitation, the repair of any surface damage, and paving,
and the repair, restoration or reconstruction of any damaged improvements caused
by such investigation or remediation.

                  (c) Seller shall promptly provide to the Buyer copies of
testing results and reports that are generated in connection with the activities
described in this Section and all related correspondence or filings with any
Governmental Authorities (collectively the "ENVIRONMENTAL REPORTS").

                  (d) After the Closing Date, Seller and its agents shall be
provided with reasonable access to the Subject Property for the sole and
exclusive purposes of performing the Identified Remediation.

                  (e) Notwithstanding anything else in this Agreement to the
contrary, Seller shall be responsible for any damages to persons or property
caused by it or its agents or representatives in performing any of the
Identified Remediation.

        8.12      ASHLAND LITIGATION.  With respect to any claim that Seller and
the Company presently have or hereafter may have against Ashland Oil, Inc.
("ASHLAND") and ATEC, Inc. ("ATEC") under the Purchase and Sale Agreement dated
January 12, 1990, as amended, among

                                             -44-
<PAGE>
Ashland, ATEC and Seller, Seller shall continue to prosecute, control and defend
such claims (or with respect to future matters, initiate, prosecute and control
any such claim). Buyer and Seller acknowledge and agree that Seller shall be
entitled to retain any monetary award and/or settlement the Seller shall obtain
against Ashland and/or ATEC in favor of Seller and the Company. The Seller shall
provide the Buyer with copies of all pleadings and other papers filed in
connection with the litigation. Any counterclaims, cross-claims or other claims
by Ashland against the Company shall be treated as Third Party Claims. Seller
agrees that any settlement of the Ashland litigation may not purport to limit
the actions of, or otherwise restrict in any way the Company, or require any
payment by the Company, without the Buyer's prior written consent which consent
shall not be unreasonably withheld. The Seller shall fully indemnify the Buyer
and the Company for all Buyer's Losses and Environmental Costs associated with
the Ashland litigation.

        8.13 RECEIVABLES. To the extent any Receivables (other than Long Term
Receivables and any Receivables collected by Buyer pursuant to Section
1.1(b)(iii)) are not collected within ninety (90) days following the Closing
Date, Seller shall purchase from the Company such uncollected Receivables for a
cash price equal to the aggregate face amount thereof less the reserve for such
doubtful accounts reflected on the Closing Balance Sheet. Such purchase shall be
concluded not more than five Business Days following the conclusion of such
ninety (90) day period. To the extent any Long Term Receivables are not
collected when due following the Closing Date, Seller shall purchase from the
Company such uncollected Long Term Receivables for a cash price equal to the
aggregate face amount thereof less the reserve for such doubtful accounts
reflected on the Closing Balance Sheet. Such purchase shall be concluded not
more than five Business Days following Buyer's demand. All uncollected
Receivables purchased pursuant to this Section 8.13 are herein called the
"REACQUIRED RECEIVABLES". Buyer will cause the Company to apply all credits and
payments against the oldest invoices, consistent with the Company's past
practice. Buyer covenants and agrees that it will cause the Company to use all
diligent efforts in the collection of the Receivables and will assist Seller in
such collection efforts of the Reacquired Receivables as are consistent with
past collection practices of the Company. Seller shall have the right to audit
the Company's handling of the Reacquired Receivables after Closing. Seller shall
not have any liability for a breach of the representation and warranty in
Section 2.17 with respect to the Reacquired Receivables. All Long Term
Receivables outstanding on the date of this Agreement are identified by account
debtor, amount, invoice date and due date in SCHEDULE 8.13, which the Seller
shall update on the Closing Date.

        8.14 LIMITATION AS TO INDEMNIFIED PARTIES' OWN NEGLIGENCE. The
obligations of the Indemnifying Parties under this Article VIII to indemnify the
Indemnified Parties shall be limited to the extent the cause or alleged cause
(in whole or in part) of the Buyer's Losses, Seller's Losses or Environmental
Costs for which a claim for indemnification is made hereunder is also the result
of the concurrent, active or passive, imputed technical or other negligence, or
fault of the party seeking indemnification.

        8.15      PENSION PLANS.  It is acknowledged and agreed by the parties 
hereto that, except as otherwise provided in this Section 8.15, on and after the
Closing neither Seller nor any affiliate

                                             -45-
<PAGE>
of Seller shall have any responsibility whatsoever for the maintenance,
administration, and payment of benefits from the Beaird Plans. As soon as
practicable after the Closing, Buyer shall establish a trust qualified under
Section 501(a) of the Code to fund benefits payable under the Beaird Industries,
Inc. Pension Plan (the "Beaird Pension Plan"), and Seller shall cause the
trustee of the Trinity Industries, Inc. Master Retirement Trust (the "Master
Trust") to transfer all assets thereunder attributable to the Beaird Pension
Plan (as determined by such trustee in accordance with its books and records
maintained for the purpose of providing separate accounting for the assets of
each plan participating in such trust) to the trust so established by Buyer;
provided, however, that the amount so transferred shall first be reduced by the
allocable share of fees and expenses incurred by the Beaird Pension Plan under,
and payable to the trustee of, the Master Trust during the period from the
Closing Date to the date of such transfer. Buyer and Seller agree to take any
and all action, including the filing of any documents required by Federal law,
necessary to facilitate such transfer of assets.

                                   ARTICLE IX
                                   TAX MATTERS

        9.1       SECTION 338(H)(10) ELECTION.

                  (a) Buyer and Seller covenant and agree to make an election
under Section 338(h)(10) of the Code for federal income tax purposes with
respect to the acquisition of the stock of the Company pursuant to this
Agreement and to make a similar election for the purpose of any provision of
state or local income tax law which is comparable to Section 338(h)(10) of the
Code. Buyer shall prepare the form or forms which are required to make each such
election ("FORMS") and subject to the approval of the Forms by Seller (such
approval not to be unreasonably withheld), Seller shall execute such Forms after
which Buyer shall file such Forms as required by law.

                  (b) In preparing the Forms, Buyer will allocate the amount
deemed to have been paid for the Company's assets for federal income tax
purposes in accordance with applicable law and in doing so the fair market
values of those assets will be determined by Buyer, subject to the approval of
Seller (which approval shall not be unreasonably withheld). Upon approval by
Seller, such allocation will be binding absent manifest error. Buyer and Seller
recognize that the Purchase Price does not include the acquisition expenses of
Buyer and agree that Buyer will allocate those expenses appropriately in its
discretion. Each of Seller and Buyer agrees (i) to file its federal income and
other Tax Returns reflecting such allocations, (ii) to take no position contrary
thereto unless required to do so pursuant to a "determination" (as defined in
Section 1313(a) of the Code) and (iii) to cooperate in the preparation of any
forms or reports required to be filed in connection with the transactions
effected pursuant to this Agreement.

        9.2       LIABILITY FOR TAXES AND RELATED MATTERS.

                  (a) Seller shall be liable for and timely pay(i) all Taxes
which are imposed on or incurred by the Company for any period for purpose of
computing Taxes ending on or before the Closing Date (including any Taxes which
are solely attributable to the election under Section 338(h)(10) of the Code for
the Company or any analogous elections under state law), (ii) (A) all Taxes for
which the Company is liable by reason of having been a member of an affiliated,
combined, unitary or other group, and (B) income Taxes of another Person for
which the Company is liable as transferee or successor or by contract, for any
period ending on or before the Closing Date and (iii) a portion, determined as
described below, of any other Taxes which are imposed on or incurred by the
Company for any period for purposes of computing Taxes which begins before and
ends after the Closing Date (a "STRADDLE PERIOD"). Buyer shall be liable for all
other Taxes which are imposed on or incurred by the Company and for any Taxes
incurred as the result of Buyer causing any sale, exchange, or distribution of
the assets of the Company on the Closing Date other than Taxes resulting solely
from an election under Section 338(h)(10) of the Code or analogous elections
under state law. Should any other Taxes be imposed on or incurred by the Company
for any Straddle Period, Seller shall be liable for only the portion of such
Taxes (which shall in no event exceed the amount of Taxes being apportioned)
which is attributable to the taxable events and activities (including based upon
or related to income or receipts) which occurred during the Straddle Period and
on or before the Closing Date; provided that ad valorem Taxes and state
franchise Taxes (other than franchise Taxes measured by net income) and any
other Taxes computed in a similar manner as ad valorem Taxes and state franchise
Taxes (other than franchise Taxes measured by net income) ("SIMILAR TAXES")
shall be determined by prorating such Taxes for a Straddle Period on a daily
basis. Any allocation of income, deductions or other Tax items required to
determine any Taxes attributable to any period including or ending on the
Closing Date shall be made by means of a closing of the books of the Company as
of the Closing Date.

                  (b) Seller shall indemnify Buyer and the Company, and Buyer
shall indemnify Seller, in respect of the Taxes for which the indemnifying party
is liable pursuant to Section 9.2(a) and for the reasonable fees and expenses of
the indemnitee's advisors which are incurred thereby in connection with
obtaining such payment. In addition, the amount of such payment shall be
increased by the amount if any which is necessary so that after the payment by
the indemnitee of Taxes which the indemnitee incurs as a result of receipt of
the payments pursuant to this Section 9.2(b) such indemnitee will retain the
amount which is described in the first sentence of this Section 9.2(b).

                  (c) If Buyer or any affiliate of Buyer receives a refund of
any Taxes described in the first sentence of Section 9.2(a), then Buyer shall
cause the amount of such refund to be paid to Seller promptly after receipt of
such refund. If Seller or any affiliate of Seller receives a refund of any Taxes
described in the second sentence of Section 9.2(a), then Seller shall cause the
amount of such refund to be paid to Buyer promptly after receipt of such refund.

                  (d) Seller shall be responsible for the preparation (in
accordance with past practices) and filing of all Tax Returns for the Company
for periods for purposes of computing Taxes ending on or before the Closing
Date. Seller shall include the Company in the filing of its consolidated federal
income Tax Return and shall cause the Company to be included in any combined,
unitary or consolidated state, local or foreign Tax Returns required or
permitted to be filed by the Seller for the Company's periods or portions
thereof ending on or including the Closing Date. Buyer shall be responsible for
the preparation and filing of all other Tax Returns which relate to the Company.

                  (e) Any tax sharing or allocation agreement between the
Company and either Seller or another member of the Seller's Group is terminated
as of the Closing Date and will have no further effect for any taxable year
(whether the current taxable year, a future taxable year or a past taxable
year).

        9.3 ASSISTANCE AND COOPERATION. After the Closing Date, each of Seller
and Buyer agree:

                  (a) To assist (and cause their respective affiliates to
assist) the other party in preparing any Tax Returns which such other party is
responsible for preparing and filing in accordance with Section 9.2(d),
cooperate fully in preparing for any audits of, or disputes with taxing
authorities regarding, any Tax Returns or Tax of the Company and make available
to the other and to any taxing authority as reasonably requested all
information, records, and documents relating to the Tax liabilities of the
Company as set forth herein. Seller and Buyer shall also make available to the
other, as reasonably requested and available, personnel responsible for
preparing or maintaining information, records and documents in connection with
Taxes as well as related litigation.

                  (b) To preserve all such information, records and documents
until the expiration of any applicable statutes of limitation or extensions
thereof and as otherwise required by law.

                  (c) To provide timely notice to the other in writing of any
pending or threatened tax audits or assessments related to the Company for
periods beginning prior to the Closing Date and furnish the other with copies of
all correspondence received from any taxing authority in connection with any tax
audit or information request with respect to any such period.

                  (d) In the event of an audit or dispute with a taxing
authority concerning Taxes for which a party is liable pursuant to Section
9.2(a), that party will be entitled to control the proceedings related to such
Taxes (including action taken to pay, compromise or settle such Taxes), except
that Seller will in any event be entitled to control any proceedings which
relate to or impact a consolidation or combined return filed by Seller and one
or more of its subsidiaries. The party which is not entitled to control any such
proceedings shall be afforded a reasonable opportunity to participate in such
proceedings at its own expense.

        9.4 PAYMENT.

                  (a) All Taxes (including Taxes owed after a compromise or
settlement of an audit or dispute with a taxing authority) shall be paid to the
taxing authority by the party which is legally responsible therefor.

                  (b) Upon payment of any Taxes with respect to which a party is
entitled to receive indemnification hereunder, such party shall submit an
invoice to the indemnifying party stating that such Taxes have been paid and
giving in reasonable detail the particulars relating thereto. The indemnifying
party shall remit payment for such Taxes promptly upon receipt of such invoice.

        9.5 SURVIVAL OF OBLIGATIONS. Subject to the limitations set forth in
Section 10.10(b), the obligations of the parties set forth in this Article IX
shall be unconditional and absolute and shall remain in effect without
limitation as to time.

                                           ARTICLE X

                                         MISCELLANEOUS

        10.1 ENTIRE AGREEMENT. This Agreement and the other Transaction
Documents (including the exhibits and schedules hereto and thereto) constitutes
the entire agreement and supersedes all prior agreements and understandings,
both written and oral, between the parties hereto with respect to the subject
matter hereof.

        10.2 SUCCESSORS AND ASSIGNS. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective successors and permitted assigns. Neither this Agreement nor any
rights, interests or obligations hereunder may be assigned by any party hereto
without the prior written consent of all other parties hereto, and any purported
assignment in violation of this Section 10.2 shall be null and void; PROVIDED,
HOWEVER, that Buyer may (a) collaterally assign its rights and obligations
hereunder in connection with the financing of the acquisition, and (b) assign
its rights and obligations hereunder to any direct or indirect owner of all of
the outstanding equity interests thereof or to any successor in interest whether
by merger or consolidation. If any party, in a single transaction or series of
related transactions, sells, leases, exchanges, or otherwise disposes of all or
substantially all of its property and assets, such party (the "SELLING PARTY")
shall, as a condition precedent to any such transaction, cause effective
provision to be made so that the Person acquiring such property and assets (the
"ACQUIRING PARTY") shall become bound by and replace said Selling Party under
this Agreement; and each other party (each "NON-SELLING PARTY") hereby agrees
that such Non-Selling Party shall in such event continue to be bound by the
terms hereof and recognize such Acquiring Party in replacement of said Selling
Party. Notwithstanding the foregoing, any assignment by Buyer (other than
pursuant to clause (a) above in this Section to a lender that neither directly
or indirectly competes with Seller in the "Trinity Business", as defined in the
Noncompetition Agreement, nor is owned or controlled by a party that

                                             -49-
<PAGE>
directly or indirectly competes with Seller in the Trinity Business) shall
require the prior written consent of Seller, which consent shall not be
unreasonably withheld.

        10.3 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original
and all of which shall constitute the same instrument.

        10.4 HEADINGS. The headings of the articles and sections of this
Agreement are inserted for convenience only and shall not be deemed to
constitute part of this Agreement or to affect the construction hereof.

        10.5 CONSTRUCTION. As used in this Agreement, the words "herein,"
"hereof" and "hereunder" and other words of similar import refer to this
Agreement as a whole and not to any particular article, section, paragraph or
other subdivision thereof.

        10.6 MODIFICATION AND WAIVER. Any of the terms or conditions of this
Agreement may be waived in writing at any time by the party which is entitled to
the benefits thereof, and this Agreement may be modified or amended by a written
instrument executed by Buyer and Seller. No supplement, modification or
amendment of this Agreement shall be binding unless executed in writing by all
of the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provision hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.

        10.7 SCHEDULES, ETC. All exhibits and schedules annexed hereto are
expressly made a part of this Agreement as though fully set forth herein.
Throughout the Schedules furnished by Seller to Buyer, Seller has attempted to
recite the text of the representations and warranties of Seller contained in
this Agreement so as to provide a context for the response of Seller in the
Schedules. Accordingly, other than in those instances where this Agreement notes
that exceptions to a representation or warranty of Seller may be listed on a
corresponding schedule, and such exceptions are specifically noted, if any
language contained on any schedule modifies or in any way conflicts with a
representation or warranty of Seller contained in this Agreement, the terms of
such representation and warranty shall govern exclusively and such language in
the schedules shall be disregarded.

        10.8 NOTICES. Any notice, request, instruction, document or other
communication to be given hereunder by any party hereto to any other party
hereto shall be in writing and validly given if (a) delivered personally, (b)

prior to the proposed date of issuance. Each such request for issuance of a
Letter of Credit shall be sent by electronic transfer or facsimile, confirmed
immediately in an original writing, in the form of a Letter of Credit Request
Form, and shall specify in form and detail satisfactory to the Issuing Bank: (i)
the proposed date of issuance of the Letter of Credit (which shall be a Business
Day); (ii) the face amount of the Letter of Credit; (iii) the expiry date of the
Letter of Credit; (iv) the name and address of the beneficiary thereof; (v) the
conditions permitting a drawing or drawings thereunder; (vi) the form of the
standby letter of credit; (vii) whether such Letter of Credit shall permit a
single drawing or multiple drawings; and (viii) such other matters as the
Issuing Bank may reasonably require.

                  (b) At least one (1) Business Day prior to the Issuance of any
Letter of Credit, the Issuing Bank will confirm with the Agent (by telephone or
in writing) that the Agent has received a copy of the Letter of Credit Request
from the Borrower and, if not, the Issuing Bank will provide the Agent with a
copy thereof. Unless the Issuing Bank has received notice on or before the
Business Day immediately preceding the date the Issuing Bank is to Issue a
requested Letter of Credit from the Agent (A) directing the Issuing Bank not to
issue such Letter of Credit because such Issuance is not then permitted under
subsection 2.10; or (B) that one or more conditions specified in Article VI are
not then satisfied; then, subject to the terms and conditions hereof, the
Issuing Bank

                                            - 18 -
<PAGE>
shall, on the requested date, issue a Letter of Credit for the account of the
Borrower in accordance with the Issuing Bank's usual and customary business
practices.

                  (c) From time to time while a Letter of Credit is outstanding
and prior to the Termination Date, the Issuing Bank will, upon the written
request of the Borrower received by the Issuing Bank (with a copy sent by the
Borrower to the Agent) at least five (5) business days (or such shorter time as
the Issuing Bank may agree in a particular instance in its sole discretion)
prior to the proposed date of amendment, amend any Letter of Credit issued by
it. Each such request for amendment of a Letter of Credit shall be made by
electronic transfer or facsimile, confirmed immediately in an original writing
or by electronic transfer, made in the form of a Letter of Credit Request Form
and shall specify in form and detail satisfactory to the Issuing Bank: (i) the
Letter of Credit to be amended; (ii) the proposed date of amendment of the
Letter of Credit (which shall be a Business Day); (iii) the nature of the
proposed amendment; and (iv) such other matters as the Issuing Bank may require.
The Issuing Bank shall be under no obligation to amend any Letter of Credit if:
(A) the Issuing Bank would have no obligation at such time to issue such Letter
of Credit in its amended form under the terms of this Agreement; or (B) the
beneficiary of any such Letter of Credit does not accept the proposed amendment
to the Letter of Credit. The Agent will promptly notify the Banks of the receipt
by it of any Letter of Credit Request Form.

                  (d) The Issuing Bank and the Banks agree that, while a Letter
of Credit is outstanding and prior to the Termination Date, at the option of the
Borrower and upon the written request of the Borrower received by the Issuing
Bank (with a copy sent by the Borrower to the Agent) at least five (5) days (or
such shorter time as the Issuing Bank may agree in a particular instance in its
sole discretion) prior to the proposed date of notification of renewal, the
Issuing Bank shall be entitled to authorize the automatic renewal of any Letter
of Credit issued by it. Each such request for renewal of a Letter of Credit
shall be made by electronic transfer or facsimile, confirmed immediately in an
original writing or by electronic transfer, in the form of a Letter of Credit
Request Form, and shall specify in form and detail reasonably satisfactory to
the Issuing Bank: (i) the Letter of Credit to be renewed; (ii) the proposed date
of notification of renewal of the Letter of Credit (which shall be a Business
Day); (iii) the revised expiry date of the Letter of Credit; and (iv) such other
matters as the Issuing Bank may reasonably require. The Issuing Bank shall be
under no obligations to renew any Letter of Credit if: (A) the Issuing Bank
would have no obligation at such time to issue or amend such Letter of Credit in
its renewed form under the terms of this Agreement; or (B) the beneficiary of
any such Letter of Credit does not accept the proposed renewal of the Letter of
Credit. If any outstanding Letter of Credit shall provide that it shall be
automatically renewed unless the beneficiary thereof receives notice from the
Issuing Bank that such Letter of Credit shall not be renewed, and if at the time
of renewal the Issuing Bank would be entitled to authorize the automatic renewal
of such Letter of Credit in accordance with this subsection 2.11(d) upon the
request of the Borrower but the Issuing Bank shall not have received any Letter
of Credit Request Form from the Borrower with respect to such renewal or other
written direction by the Borrower with respect thereto, the Issuing Bank shall
nonetheless be permitted to allow such Letter of Credit to renew, and the
Borrower and the Banks hereby authorize such renewal, and, accordingly, the
Issuing Bank shall be deemed to have received a Letter of Credit Request Form
from the Borrower requesting such renewal.

<PAGE>
                  (e) This Agreement shall control in the event of any conflict
with any Letter of Credit related document (other than any Letter of Credit).

                  (f) The Issuing Bank will also deliver to the Agent,
concurrently or promptly following its delivery of a Letter of Credit, or
amendment to or renewal of a Letter of Credit, to an advising Bank or a
beneficiary, a true and complete copy of each such Letter of Credit or amendment
to or renewal of a Letter of Credit.

        Section 2.12   RISK PARTICIPATION, DRAWINGS AND REIMBURSEMENTS.

                  (a) Immediately upon the Issuance of each Letter of Credit,
each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees
to, purchase from the Issuing Bank a participation in such Letter of Credit and
each drawing thereunder in an amount equal to the product of (i) the Pro Rata
Share of such Bank, times (ii) the maximum amount available to be drawn under
such Letter of Credit and the amount of such drawing, respectively. For purposes
of Section 2.1, each Issuance of a Letter of Credit shall be deemed to utilize
the Commitment of each Bank by an amount equal to the amount of such
participation.

                  (b) In the event of any request for a drawing under a Letter
of Credit by the beneficiary or transferee thereof, the Issuing Bank will
promptly notify the Borrower. Any notice given by the Issuing Bank or the Agent
pursuant to this subsection 2.12(b) may be oral if immediately confirmed in
writing (including by facsimile); provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such
notice. The Borrower shall reimburse the Issuing Bank prior to 11:00 a.m.
(Dallas time), on each date that any amount is paid by the Issuing Bank under
any Letter of Credit (each such date, an "Honor Date"), in an amount equal to
the amount so paid by the Issuing Bank. In the event the Borrower fails to
reimburse the Issuing Bank for the full amount of any drawing under any Letter
of Credit by 11:00 a.m. (Dallas time) on the Honor Date, the Issuing Bank will
promptly notify the Agent and the Agent will promptly notify each Bank thereof,
and the Borrower shall be deemed to have requested that Base Rate Advances be
made by the Banks to be disbursed on the Honor Date under such Letter of Credit,
subject to the amount of the unutilized portion of the Commitment and subject to
the conditions set forth in Section 6.2.

                  (c) Each Bank shall upon any notice pursuant to subsection
2.12(b) make available to the Agent for the account of the relevant Issuing Bank
an amount in dollars and in immediately available funds equal to its Pro Rata
Share of the amount of the drawing, whereupon the participating Banks shall
(subject to subsection 2.12(d)) each be deemed to have made an Advance
consisting of a Base Rate Advance to the Borrower in that amount. If any Bank so
notified fails to make available to the Agent for the account of the Issuing
Bank the amount of such Bank's Pro Rata Share of the amount of the drawing by no
later than 1:00 p.m. (Dallas time) on the Honor Date, then interest shall accrue
on such Bank's obligation to make such payment, from the Honor Date to the date
such Bank makes such payment, at a rate per annum equal to the Federal Funds
Rate in effect from time to time during such period. The Agent will promptly
give notice of the occurrence of the Honor Date, but failure of the Agent to
give any such notice on the Honor Date

                                            - 20 -
<PAGE>
or in sufficient time to enable any Bank to effect such payment on such date
shall not relieve such Bank from its obligations under this Section 2.12.

                  (d) With respect to any unreimbursed drawing that is not
converted into Advances consisting of Base Rate Advances to the Borrower in
whole or in part, because of the Borrower's failure to satisfy the conditions
set forth in Section 6.2 or for any other reason, the Borrower shall be deemed
to have incurred from the Issuing Bank a Letter of Credit Advance (herein so
called) in the amount of such drawing, which Letter of Credit Advance shall be
due and payable on demand (together with interest) and shall bear interest at a
rate per annum equal to the Default Rate for the period from and including the
date of such drawing to but excluding the date of the Letter of Credit Advance,
together with all accrued, unpaid interest thereon, is paid in full, and each
Bank's payment to the Issuing Bank pursuant to subsection 12.12(c) shall be
deemed payment in respect of its participation in such Letter of Credit Advance
and shall constitute a participation in such Letter of Credit Advance in
accordance with such Bank's Pro Rate Share in satisfaction of its participation
obligation under this Section 12.12.

                  (e) Each Bank's obligation in accordance with this Agreement
to make the Advances of Letter of Credit Advances, as contemplated by this
Section 12.12, as a result of a drawing under a Letter of Credit, shall be
absolute and unconditional and without recourse to the Issuing Bank and shall
not be affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right which such Bank may have against the Issuing
Bank, the Borrower or any other Person for any reason whatsoever; (ii) the
occurrence or continuance of a Default, an Event of Default; or (iii) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing; provided, however, that each Bank's obligation to make Advances
under this Section 12.12 is subject to the conditions set forth in Section 6.2.

        Section 2.13   INDEMNIFICATION.

                  (a) Upon (and only upon) receipt by the Agent for the account
        of the Issuing Bank of immediately available funds from the Borrower (i)
        in reimbursement of any payment made by the Issuing Bank under the
        Letter of Credit with respect to which any Bank has paid the Agent for
        the account of the Issuing Bank for such Bank's participation in the
        Letter of Credit pursuant to Section 2.12 or (ii) in payment of interest
        thereon, the Agent will pay to each Bank, in the same funds as those
        received by the Agent for the account of the Issuing Bank, the amount of
        such Bank's Pro Rata Share of such funds, and the Issuing Bank shall
        receive the amount of the Pro Rata Share of such funds of any Bank that
        did not so pay the Agent for the account of the Issuing Bank.

                  (b) If the Agent or the Issuing Bank is required at any time
        to return to the Borrower, or to a trustee, receiver, liquidator,
        custodian, or any official in any insolvency proceeding of the types
        described in Sections 11.1(d) or (e) (each an "Insolvency Proceeding"),
        any portion of the payments made by the Borrower to the Agent for the
        account of the Issuing Bank pursuant to subsection 2.13(a) in
        reimbursement of a payment made under the Letter of Credit or interest
        or fee thereon, each Bank shall, on demand of the Agent, forthwith
        return to the Agent or the Issuing Bank the amount of its Pro Rata Share

                                            - 21 -
<PAGE>
        of any amounts so returned by the Agent or the Issuing Bank plus
        interest thereon from the date such demand is made to the date such
        amounts are returned by such Bank to the Agent or the Issuing Bank, at a
        rate per annum equal to the Federal Funds Rate in effect from time to
        time.

        Section 2.14   ROLE OF THE ISSUING BANK.

                  (a) Each Bank and the Borrower agree that, in paying any
        drawing under a Letter of Credit, the Issuing Bank shall not have any
        responsibility to obtain any document (other than any sight draft and
        certificates expressly required by the Letter of Credit) or to ascertain
        or inquire as to the validity or accuracy of any such document or the
        authority of the Person executing or delivering any such document.

                  (b) No Agent-related Person nor any of the respective
        correspondents, participants or assignees of the Issuing Bank shall be
        liable to any Bank for: (i) any action taken or omitted in connection
        herewith at the request or with the approval of the Banks (including the
        Required Banks, as applicable); (ii) any action taken or omitted in the
        absence of gross negligence or willful misconduct; or (iii) the due
        execution, effectiveness, validity or enforceability of any Letter of
        Credit related document.

                  (c) The Borrower hereby assumes all risks of the acts or
        omissions of any beneficiary or transferee with respect to its use of
        any Letter of Credit; provided, however, that this assumption is not
        intended to, and shall not, preclude the Borrower's pursuing such rights
        and remedies as it may have against the beneficiary or transferee at law
        or under any other agreement. No Agent-related Person, nor any of the
        respective correspondents, participants or assignees of the Issuing
        Bank, shall be liable or responsible for any of the matters described in
        clauses (i) through (vii) of Section 2.15; provided, however, anything
        in such clauses to the contrary notwithstanding, that the Borrower may
        have a claim against the Issuing Bank, and the Issuing Bank may be
        liable to the Borrower, to the extent, but only to the extent, of any
        direct, as opposed to consequential or exemplary, damages suffered by
        the Borrower which the Borrower proves were caused by the Issuing Bank's
        willful misconduct or gross negligence or the Issuing Bank's willful
        failure to pay under any Letter of Credit after the presentation to it
        by the beneficiary of a sight draft and certificate(s) strictly
        complying with the terms and conditions of a Letter of Credit. In
        furtherance and not in limitation of the foregoing: (i) the Issuing Bank
        may accept documents that appear on their face to be in order, without
        responsibility for further investigation, regardless of any notice or
        information to the contrary; and (ii) the Issuing Bank shall not be
        responsible for the validity or sufficiency of any instrument
        transferring or assigning or purporting to transfer or assign a Letter
        of Credit or the rights or benefits thereunder or proceeds thereof, in
        whole or in part, which may prove to be invalid or ineffective for any
        reason.

        Section 2.15 OBLIGATIONS ABSOLUTE. The Obligations of the Borrower under
this Agreement and any Letter of Credit related document to reimburse the
Issuing Bank for a drawing under a Letter of Credit, and to repay any Letter of
Credit Advance and any drawing under a Letter of Credit converted into an
Advance, shall be unconditional and irrevocable, and shall be paid

                                            - 22 -
<PAGE>
strictly in accordance with the terms of this Agreement and each such other
Letter of Credit related document under all circumstances, including the
following:

                       (i)   any lack of validity or enforceability of this 
                  Agreement or any Letter of Credit related document;

                       (ii) any change in the time, manner or place of payment
                  of, or in any other term of, all or any of the Obligations of
                  the Borrower in respect of any Letter of Credit or any other
                  amendment or waiver of or any consent to departure from all or
                  any of the Letter of Credit related document;

                       (iii) the existence of any claim, set-off, defense or
                  other right that the Borrower may have at any time against any
                  beneficiary or any transferee of any Letter of Credit (or any
                  Person for whom any such beneficiary or any such transferee
                  may be acting), the Issuing Bank or any other Person, whether
                  in connection with this Agreement, the transactions
                  contemplated hereby or by the Letter of Credit Related
                  Documents or any unrelated transaction;

                       (iv) any draft, demand, certificate or other document
                  presented under any Letter of Credit proving to be forged,
                  fraudulent, invalid or insufficient in any respect or any
                  statement therein being untrue or inaccurate in any respect;
                  or any loss or delay in the transmission or otherwise of any
                  document required in order to make a drawing under any Letter
                  of Credit;

                       (v) any payment by the Issuing Bank under any Letter of
                  Credit against presentation of a draft or certificate that
                  does not strictly comply with the terms of any Letter of
                  Credit; or any payment made by the Issuing Bank under any
                  Letter of Credit to any Person purporting to be a trustee in
                  bankruptcy, debtor-in-possession, assignee for the benefit of
                  creditors, liquidator, receiver or other representative of or
                  successor to any beneficiary or any transferee of any Letter
                  of Credit, including any arising in connection with any
                  Insolvency Proceeding;

                       (vi) any exchange, release or non-perfection of any
                  collateral, or any release or amendment or waiver of or
                  consent to departure from any other guarantee, for all or any
                  of the obligations of the Borrower in respect of any Letter of
                  Credit; or

                       (vii) any other circumstance or happening whatsoever,
                  whether or not similar to any of the foregoing, including any
                  other circumstance that might otherwise constitute a defense
                  available to, or a discharge of, the Borrower or a Guarantor,
                  except for errors and omissions caused by an Issuing Bank's
                  gross negligence or willful misconduct.

        Section 2.16 CASH COLLATERAL PLEDGE. Upon (i) the request of the Agent,
(A) if the Issuing Bank has honored any full or partial drawing request on any
Letter of Credit and such drawing has

                                            - 23 -
<PAGE>
resulted in a Letter of Credit Advance hereunder, or (B) if, as of the
Termination Date, any Letters of Credit may for any reason remain outstanding
and partially or wholly undrawn, or (ii) the occurrence of the circumstances
described in Section 3.2 requiring the Borrower to Cash Collateralize Letters of
Credit, then, the Borrower shall immediately Cash Collateralize the Letter of
Credit Liabilities in an amount equal to such Letter of Credit Liabilities. The
Borrower hereby grants the Agent, for the benefit of the Agent, the Issuing Bank
and the Banks, a security interest in all such Cash Collateral. Cash Collateral
shall be maintained in blocked, non-interest bearing deposit accounts at
Comerica. The Borrower agrees to enter into documentation evidencing such
security interest in the Cash Collateral, in form and substance satisfactory to
Agent and the Required Banks in their reasonable discretion.

        Section 2.17   LETTER OF CREDIT FEES.

                  (a) The Borrower shall pay to the Agent for the account of
        each of the Banks a floating letter of credit fee with respect to the
        Letters of Credit equal to the greater of (i) Five Hundred and No/100
        Dollars ($500) or (ii) one percent per annum (1%) upon the face amount
        of outstanding Letters of Credit, computed on a quarterly basis in
        arrears on the last Business Day of each calendar quarter based upon
        Letters of Credit outstanding for that quarter as calculated by the
        Agent. Such letter of credit fees shall be due and payable monthly in
        arrears on the last Business Day of each calendar month during which
        Letters of Credit are outstanding, commencing on the first such monthly
        date to occur after the date hereof, through the Termination Date (or
        such later date upon which the outstanding Letters of Credit shall
        expire), with the final payment to be made on the Termination Date (or
        such later expiration date).

                  (b) The Company shall pay to the Issuing Bank from time to
        time on demand the normal and customary issuance, presentation,
        amendment and other customary processing fees, and other standard costs
        and charges, of the Issuing Bank relating to letters of credit as from
        time to time in effect.

        Section 2.18 UNIFORM CUSTOMS AND PRACTICE. The Uniform Customs and
Practice for Documentary Credits as published by the International Chamber of
Commerce most recently at the time of issuance of any Letter of Credit shall
(unless otherwise expressly provided in the Letters of Credit) apply to the
Letters of Credit.

        Section 2.19 EXISTING LETTERS OF CREDIT. The letters of credit described
on Schedule 2.19 hereto issued by Comerica shall be deemed to be Letters of
Credit issued by the Issuing Bank hereunder pursuant to the Letter of Credit
Commitment and shall be subject to and governed by, in all respects, this
Agreement to the same effect as if such Letters of Credit were issued pursuant
to this Agreement except as to Letter of Credit fees already collected by
Comerica.

                                          ARTICLE III

                                            PAYMENTS

        Section 3.1 METHOD OF PAYMENT. All payments of principal, interest, and
other amounts to be made by the Borrower under this Agreement and the other Loan
Documents shall be made to the Agent at the Principal Office for the account of
each Bank's Applicable Lending Office in Dollars and in immediately available
funds, without setoff, deduction, or counterclaim, not later than 11:00 a.m.,
Houston, Texas time on the date on which such payment shall become due (each
such payment made after such time on such due date to be deemed to have been
made on the next succeeding Business Day). The Borrower shall, at the time of
making each such payment, specify to the Agent the sums payable by the Borrower
under this Agreement and the other Loan Documents to which such payment is to be
applied (and in the event that the Borrower fails to so specify, or if an Event
of Default has occurred and is continuing, the Agent may apply such payment to
the Obligations in such order and manner as it may elect in its sole discretion,
subject to Section 3.3 hereof). Each payment received by the Agent under this
Agreement or any other Loan Document for the account of a Bank shall be paid
promptly to such Bank, in immediately available funds, for the account of such
Bank's Applicable Lending Office. Whenever any payment under this Agreement or
any other Loan Document shall be stated to be due on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of the
payment of interest and commitment fee, as the case may be.

        Section 3.2    PREPAYMENT.

                  (a) The Borrower may, upon prior notice to the Agent in the
        case of Base Rate Advances on the day of prepayment unless such
        prepayments are being made on Base Rate Advances pursuant to the
        Borrower's sweep authorizations then in effect, and at least three (3)
        Business Days' prior notice to the Agent in the case of Eurodollar
        Advances, prepay the Advances in whole at any time or from time to time
        in part without premium or penalty but with accrued interest to the date
        of prepayment on the amount so prepaid, provided that (a) Eurodollar
        Advances may be prepaid only on the last day of the Interest Period for
        such Advances, and (b) each partial prepayment of Eurodollar Advances
        shall be in the principal amount of $100,000 or an integral multiple
        thereof. All notices under this Section shall be irrevocable and shall
        be given not later than 11:00 a.m. Dallas, Texas time on the day which
        is not less than the number of Business Days specified above for such
        notice.

                  (b) If on any date the Letter of Credit Liabilities exceed the
        Letter of Credit Commitment, the Borrower shall Cash Collateralize on
        such date the outstanding Letters of Credit in an amount equal to the
        excess of the maximum amount then available to be drawn under the
        Letters of Credit over the aggregate Letter of Credit Commitment. If on
        any date after giving effect to any Cash Collateralization made on such
        date pursuant to the preceding sentence, (i) the aggregate amount of
        Advances then outstanding plus the amount of Letter of Credit
        Liabilities exceeds (ii) the lesser of the Commitment or the Borrowing
        Base, the

                                            - 25 -
<PAGE>
        Borrower shall immediately, and without notice or demand, prepay the
        outstanding principal amount of the Advances by an amount equal to the
        applicable excess.

        Section 3.3 PRO RATA TREATMENT. Except to the extent otherwise provided
herein: (a) each Advance shall be by the Banks under Section 2.1, each payment
of commitment fee under Section 2.8 shall be made for the account of the Banks,
and each termination or reduction of the Commitments under Section 2.9 shall be
applied to the Commitments of the Banks, pro rata according to the respective
unused Commitments; (b) the making, Conversion, and Continuation of Advances of
a particular Type (other than Conversions provided for by Section 4.4) shall be
made pro rata among the Banks holding Advances of such Type according to the
amounts of their respective Commitments; (c) each payment and prepayment of
principal of or interest on Advances by the Borrower of a particular Type shall
be made to the Agent for the account of the Banks holding Advances of such Type
pro rata in accordance with the respective unpaid principal amounts of such
Advances held by such Banks; and (d) Interest Periods for Advances of a
particular Type shall be allocated among the Banks holding Advances of such Type
pro rata according to the respective principal amounts held by such Banks.

        Section 3.4 NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Agent shall
have been notified by a Bank or the Borrower (the "Payor") prior to the date on
which such Bank is to make payment to the Agent of the proceeds of a Loan to be
made by it hereunder or the Borrower is to make a payment to the Agent for the
account of one or more of the Banks, as the case may be (such payment being
herein called the "Required Payment"), which notice shall be effective upon
receipt, that the Payor does not intend to make the Required Payment to the
Agent, the Agent may assume that the Required Payment has been made and may, in
reliance upon such assumption (but shall not be required to), make the amount
thereof available to the intended recipient on such date and, if the Payor has
not in fact made the Required Payment to the Agent, the recipient of such
payment shall, on demand, pay to the Agent the amount made available to it
together with interest thereon in respect of the period commencing on the date
such amount was so made available by the Agent until the date the Agent recovers
such amount at a rate per annum equal to the Federal Funds Rate for such period.

        Section 3.5 WITHHOLDING TAXES. All payments by the Borrower of principal
of and interest on the Advances and of all fees and other amounts payable under
any Loan Document are payable without deduction for or on account of any present
or future taxes, duties or other charges levied or imposed by the United States
of America or by the government of any jurisdiction outside the United States of
America or by any political subdivision or taxing authority of or in any of the
foregoing through withholding or deduction with respect to any such payments. If
any such taxes, duties or other charges are so levied or imposed, the Borrower
will pay additional interest or will make additional payments in such amounts so
that every net payment of principal of and interest on the Advances and of all
other amounts payable by it under any Loan Document, after withholding or
deduction for or on account of any such present or future taxes, duties or other
charges, will not be less than the amount provided for herein or therein,
provided that the Borrower shall have no obligation to pay such additional
amounts to any Bank to the extent that such taxes, duties, or other charges are
levied or imposed by reason of the failure of such Bank to comply with the
provisions

                                            - 26 -
<PAGE>
of Section 3.6. The Borrower shall furnish promptly to the Agent for
distribution to each affected Bank, as the case may be, official receipts
evidencing any such withholding or reduction.

        Section 3.6 WITHHOLDING TAX EXEMPTION. Each Bank that is not
incorporated under the laws of the United States of America or a state thereof
agrees that it will deliver to the Borrower and the Agent two duly completed
copies of United States Internal Revenue Service Form 1001 or 4224, certifying
in either case that such Bank is entitled to receive payments from the Borrower
under any Loan Document without deduction or withholding of any United States
federal income taxes. Each Bank which so delivers a Form 1001 or 4224 further
undertakes to deliver to Borrower and the Agent two additional copies of such
form (or a successor form) on or before the date such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by the Borrower or the Agent, in
each case certifying that such Bank is entitled to receive payments from the
Borrower under any Loan Document without deduction or withholding of any United
States federal income taxes, unless an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any
such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Bank from duly completing and
delivering any such form with respect to it and such Bank advises the Borrower
and the Agent that it is not capable of receiving such payments without any
deduction or withholding of United States federal income tax.

        Section 3.7 COMPUTATION OF INTEREST. Interest on the Advances and all
other amounts payable by the Borrower hereunder shall be computed on the basis
of a year of 360 days and the actual number of days elapsed (including the first
day but excluding the last day) unless such calculation would result in a
usurious rate, in which case interest shall be calculated on the basis of a year
of 365 or 366 days, as the case may be.

        Section 4.1    ADDITIONAL COSTS.

                  (a) The Borrower shall pay within five (5) Business Days of
        the request therefor to Agent for the account of such Bank from time to
        time such amounts as such Bank may determine to be necessary to
        compensate it for any costs incurred by such Bank which such Bank
        determines are attributable to its making or maintaining of any
        Eurodollar Advances hereunder or its obligation to make any of such
        Advances hereunder, or any reduction in any amount receivable by such
        Bank hereunder in respect of any such Advances or such obligation (such
        increases in costs and reductions in amounts receivable being herein
        called "Additional Costs"), resulting from any Regulatory Change which:

                       (i) changes the basis of taxation of any amounts payable
                  to such Bank under this Agreement or its Note in respect of
                  any of such Advances (other than taxes imposed on the overall
                  net income of such Bank or its Applicable Lending

                                            - 27 -
<PAGE>
                  Office for any of such Advances by the jurisdiction in which
                  such Bank has its principal office or such Applicable Lending
                  Office);

                       (ii) imposes or modifies any reserve, special deposit,
                  minimum capital, capital ratio, or similar requirement
                  relating to any extensions of credit or other assets of, or
                  any deposits with or other liabilities or commitments of, such
                  Bank (including any of such Advances or any deposits referred
                  to in the definition of "Eurodollar Rate" in Section 1.1
                  hereof); or

                       (iii) imposes any other condition affecting this
                  Agreement or the Notes or any of such extensions of credit or
                  liabilities or commitments.

        Each Bank will notify the Borrower of any event occurring after the date
        of this Agreement which will entitle such Bank to compensation pursuant
        to this Section 4.1(a) as promptly as practicable after it obtains
        knowledge thereof and determines to request such compensation, and will
        designate a different Applicable Lending Office for the Advances
        affected by such event if such designation will avoid the need for, or
        reduce the amount of, such compensation and will not, in the sole
        opinion of such Bank, violate any law, rule, or regulation or be in any
        way disadvantageous to such Bank, provided that such Bank shall have no
        obligation to so designate an Applicable Lending Office located in the
        United States of America. Each Bank will furnish the Borrower with a
        certificate setting forth the basis and the amount of each request of
        such Bank for compensation under this Section 4.1(a). If any Bank
        requests compensation from the Borrower under this Section 4.1(a), the
        Borrower may, by notice to such Bank (with a copy to the Agent) suspend
        the obligation of such Bank to make or Continue making, or Convert
        Advances into, Advances of the Type with respect to which such
        compensation is requested until the Regulatory Change giving rise to
        such request ceases to be in effect (in which case the provisions of
        Section 4.4 hereof shall be applicable).

                  (b) Without limiting the effect of the foregoing provisions of
        this Section 4.1, in the event that, by reason of any Regulatory Change,
        any Bank either (i) incurs Additional Costs based on or measured by the
        excess above a specified level of the amount of a category of deposits
        or other liabilities of such Bank which includes deposits by reference
        to which the interest rate on Eurodollar Advances is determined as
        provided in this Agreement or a category of extensions of credit or
        other assets of such Bank which includes Eurodollar Advances or (ii)
        becomes subject to restrictions on the amount of such a category of
        liabilities or assets which it may hold, then, if such Bank so elects by
        notice to the Borrower (with a copy to the Agent), the obligation of
        such Bank to make or Continue making, or Convert Advances into, Advances
        of such Type hereunder shall be suspended until such Regulatory Change
        ceases to be in effect (in which case the provisions of Section 4.4
        hereof shall be applicable).

                  (c) Determinations and allocations by any Bank for purposes of
        this Section 4.1 of the effect of any Regulatory Change on its costs of
        maintaining its obligations to make Advances or of making or maintaining
        Advances or on amounts receivable by it in respect

                                            - 28 -
<PAGE>
        of Advances, and of the additional amounts required to compensate such
        Bank in respect of any Additional Costs, shall be conclusive, provided
        that such determinations and allocations are made on a reasonable basis.

        Section 4.2 LIMITATION ON TYPES OF ADVANCES. Anything herein to the
contrary notwithstanding, if with respect to any Fixed Rate Advances for any
Interest Period therefor:

                  (a) The Agent determines (which determination shall be
        conclusive) that quotations of interest rates for the relevant deposits
        referred to in the definition of "Eurodollar Rate" in Section 1.1 hereof
        are not being provided in the relative amounts or for the relative
        maturities for purposes of determining the rate of interest for such
        Advances as provided in this Agreement; or

                  (b) Required Banks determine (which determination shall be
        conclusive) and notify the Agent that the relevant rates of interest
        referred to in the definition of "Eurodollar Rate" in Section 1.1 hereof
        on the basis of which the rate of interest for such Advances for such
        Interest Period is to be determined do not accurately reflect the cost
        to the Banks of making or maintaining such Advances for such Interest
        Period;

then the Agent shall give the Borrower prompt notice thereof specifying the
relevant Type of Advances and the relevant amounts or periods, and so long as
such condition remains in effect, the Banks shall be under no obligation to make
additional Advances of such Type or to Convert Advances of any other Type into
Advances of such Type and the Borrower shall, on the last day(s) of the then
current Interest Period(s) for the outstanding Advances of the affected Type,
either prepay such Advances or Convert such Advances into another Type of
Advance in accordance with the terms of this Agreement.

        Section 4.3 ILLEGALITY. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Bank or its Applicable
Lending Office to (a) honor its obligation to make Eurodollar Advances hereunder
or (b) maintain Eurodollar Advances hereunder, then such Bank shall promptly
notify the Borrower (with a copy to the Agent) thereof and such Bank's
obligation to make or maintain Eurodollar Advances and to Convert other Types of
Advances into Eurodollar Advances hereunder shall be suspended until such time
as such Bank may again make and maintain Eurodollar Advances (in which case the
provisions of Section 4.4 hereof shall be applicable).

        Section 4.4 TREATMENT OF AFFECTED ADVANCES. If the Eurodollar Advances
of any Bank (Advances of such Type being hereinafter called "Affected Advances"
and such Type being herein called the "Affected Type") are to be Converted
pursuant to Section 4.1 or 4.3 hereof, such Bank's Affected Advances shall be
automatically Converted into Base Rate Advances on the last day(s) of the then
current Interest Period(s) for the Affected Advances (or, in the case of a
Conversion required by Section 4.1(b) or 4.3 hereof, on such earlier date as
such Bank may specify to the Borrower with a copy to the Agent) and, unless and
until such Bank gives notice as provided below that the circumstances specified
in Section 4.1 or 4.3 hereof which gave rise to such Conversion no longer exist:

                                            - 29 -
<PAGE>

                  (a) To the extent that such Bank's Affected Advances have been
        so Converted, all payments and prepayments of principal which would
        otherwise be applied to such Bank's Affected Advances shall be applied
        instead to its Base Rate Advances;

                  (b) All Advances which would otherwise be made or Continued by
        such Bank as Advances of the Affected Type shall be made as or Converted
        into Base Rate Advances and all Advances of such Bank which would
        otherwise be Converted into Advances of the Affected Type shall be
        Converted instead into (or shall remain as) Base Rate Advances; and

                  (c) If Advances of other Banks of the Affected Type are
        subsequently Converted into Advances of another Type (other than Base
        Rate Advances) such Bank's Base Rate Advances shall be automatically
        Converted on the Conversion date into Advances of such other Type to the
        extent necessary so that, after giving effect thereto, all Advances held
        by such Bank and the Banks whose Advances are so Converted are held pro
        rata (as to principal amounts, Types, and Interest Periods) in
        accordance with their respective Commitments.

If such Bank gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 4.1 or 4.3 hereof which gave rise to the
Conversion of such Bank's Affected Advances pursuant to this Section 4.4 no
longer exist (which such Bank agrees to do promptly upon such circumstances
ceasing to exist) at a time when Advances of the Affected Type are outstanding,
such Bank's Base Rate Advances shall be automatically Converted, on the first
day(s) of the next succeeding Interest Period(s) for such outstanding Advances
of the Affected Type to the extent necessary so that, after giving effect
thereto, all Advances held by the Banks holding Advances of the Affected Type
and by such Bank are held pro rata (as to principal amounts, Types, and Interest
Periods) in accordance with their respective Commitments.

        Section 4.5 COMPENSATION. The Borrower shall pay to the Agent for the
account of each Bank, upon the request of such Bank through the Agent, such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost, or expense incurred by it as a result
of:

                  (a) Any payment, prepayment or Conversion of a Eurodollar
        Advance for any reason (including, without limitation, the acceleration
        of the outstanding Advances pursuant to Section 11.2) on a date other
        than the last day of an Interest Period for such Advance; or

                  (b) Any failure by the Borrower for any reason (including,
        without limitation, the failure of any conditions precedent specified in
        Article VI to be satisfied) to borrow, Convert, or prepay a Fixed Rate
        Advance on the date for such borrowing, Conversion, or prepayment,
        specified in the relevant notice of borrowing, prepayment, or Conversion
        under this Agreement.

 Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
which otherwise would have accrued on the

                                            - 30 -
<PAGE>
principal amount so paid or Converted or not borrowed for the period from the
date of such payment, Conversion, or failure to borrow to the last day of the
Interest Period for such Advance (or, in the case of a failure to borrow, the
Interest Period for such Advance which would have commenced on the date
specified for such borrowing) at the applicable rate of interest for such
Advance provided for herein over (ii) the interest component of the amount such
Bank would have bid in the London interbank market (if such Advance is a
Eurodollar Advance) for Dollar deposits of leading banks and amounts comparable
to such principal amount and with maturities comparable to such period.

        Section 4.6 CAPITAL ADEQUACY. If after the date hereof, any Bank shall
have determined that the adoption or implementation of any applicable law, rule,
or regulation regarding capital adequacy (including, without limitation, any
law, rule, or regulation implementing the Basle Accord), or any change therein,
or any change in the interpretation or administration thereof by any central
bank or other Governmental Authority charged with the interpretation or
administration thereof, or compliance by such Bank (or its parent) with any
guideline, request, or directive regarding capital adequacy (whether or not
having the force of law) of any central bank or other Governmental Authority
(including, without limitation, any guideline or other requirement implementing
the Basle Accord), has or would have the effect of reducing the rate of return
on such Bank's (or its parent's) capital as a consequence of its obligations
hereunder or the transactions contemplated hereby to a level below that which
such Bank (or its parent) could have achieved but for such adoption,
implementation, change or compliance (taking into consideration such Bank's
policies with respect to capital adequacy) by an amount deemed by such Bank to
be material, then from time to time, within five (5) Business Days after demand
by such Bank (with a copy to the Agent), the Borrower shall pay to the Agent for
the account of such Bank such additional amount or amounts as will compensate
such Bank (or its parent) for such reduction. A certificate of such Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive, provided that the
determination thereof is made on a reasonable basis. In determining such amount
or amounts, such Bank may use any reasonable averaging and attribution methods.

        debtors pay all monies directly into such lock box account, which shall

        security interest in 100% of the share capital of each of Subsidiaries
        of such Person pursuant to the Pledge Agreement.

                  (f) The Borrower shall execute, and cause its Subsidiaries to

        Section 5.2 SETOFF. If an Event of Default shall have occurred and is
continuing, each Bank is hereby authorized at any time and from time to time,

the failure to give such notice shall not affect the validity of such set off
and application. The rights and remedies of each Bank hereunder are in addition
to other rights and remedies (including, without limitation, other rights of set
off) which such Bank may have.

        aggregate shall be rendered by a court or courts against the Borrower,
        any of its Subsidiaries, or any Obligated Party and the same shall not
        be discharged (or provision shall not be made for such discharge), or a
        stay of execution thereof shall not be procured, within thirty (30) days
        from the date of entry thereof and the Borrower or the relevant
        Subsidiary or Obligated Party shall not, within said period of thirty
        (30) days, or such longer period during which execution of the same
        shall have been stayed, appeal therefrom and cause the execution thereof
        to be stayed during such appeal.

                  (h) The Borrower, any Subsidiary, or any Obligated Party shall
        fail to pay when due any principal of or interest on any Debt (other
        than the Obligations), or the maturity of any such Debt shall have been
        accelerated, or any such Debt shall have been required to be prepaid
        prior to the stated maturity thereof, or any event shall have occurred

        would permit) any holder or holders of such Debt or any Person acting on
        behalf of such holder or holders to accelerate the maturity thereof or
        require any such prepayment.

                  (i) This Agreement or any other Loan Document shall cease to
        be in full force and effect or shall be declared null and void or the
        validity or enforceability thereof shall be contested or challenged by
        the Borrower, any Subsidiary, any Obligated Party or any of their
        respective shareholders, or the Borrower or any Obligated Party shall
        deny that it has any further liability or obligation under any of the
        Loan Documents, or any lien or security interest created by the Loan
        Documents shall for any reason cease to be a valid, first priority
        perfected security interest in and lien upon any of the Collateral
        purported to be covered thereby.

                                            - 51 -
<PAGE>
        Reportable Event with respect to any Plan; (iii) the filing under
        Section 4041 of ERISA of a notice of intent to terminate any Plan or the
        termination of any Plan; (iv) any event or circumstance that might
        constitute grounds entitling the PBGC to institute proceedings under
        Section 4042 of ERISA for the termination of, or for the appointment of
        a trustee to administer, any Plan, or the institution by the PBGC of any
        such proceedings; or (v) complete or partial withdrawal under Section
        4201 or 4204 of ERISA from a Multiemployer Plan or the reorganization,
        insolvency, or termination of any Multiemployer Plan; and in each case
        above, such event or condition, together with all other events or
        conditions, if any, have subjected or could in the reasonable opinion of
        Required Banks subject the Borrower to any tax, penalty, or other
        liability to a Plan, a Multiemployer Plan, the PBGC, or otherwise (or
        any combination thereof) which in the aggregate exceed or could
        reasonably be expected to exceed One Hundred Thousand and No/100 Dollars
        ($100,000).

                  (k) The Borrower or any of its Subsidiaries, or any of their
        properties, revenues, or assets, shall become the subject of an order of
        forfeiture, seizure, or divestiture (whether under RICO or otherwise)
        and the same shall not have been discharged (or provisions shall not be
        made for such discharge) within thirty (30) days from the date of entry
        thereof.

                  (l) After the Closing Date, any Person or two or more Person
        acting as a group (as defined in Section 13(d)(3) of the Securities
        Exchange Act of 1934) shall have acquired beneficial ownership (within
        the meaning of Rule 13d-3 of the Securities and Exchange Commission
        under the Securities Exchange Act of 1934) of thirty percent (30%) or
        more of the outstanding shares of voting stock of the Borrower; or
        individuals who, as of the date hereof, constitute the Board of
        Directors of the Borrower (the "Incumbent Board") cease for any reason
        to constitute at least a majority of the Board of Directors of the
        Borrower; provided, however, that any individual becoming a director of
        the Borrower subsequent to the Closing Date whose election, or
        nomination for election by the Borrower's shareholders, was approved by
        a vote of at least a majority of the directors then comprising the
        Incumbent Board, shall be considered as though such individual were a
        member of the Incumbent Board, but excluding, for this purpose, any such
        individual whose initial assumption of office occurs as a result of
        either an actual or threatened election contest (as such terms are used
        in Rule 14a-11 of Regulation 14A promulgated under the Securities
        Exchange Act of 1934) or other actual or threatened solicitation of
        proxies or consents by or on behalf of a Person other than the Board of
        Directors of the Borrower; or they shall cease to directly or indirectly
        own one hundred percent (100%) of each class of stock or other equity
        interests of Subsidiary.

                  (m) The Borrower, any Subsidiary, Guarantor or any Obligated
        Party, or any combination of one or more of such Persons, shall fail to
        pay when due any principal or interest on any Debt (other than the
        Obligations) payable to Comerica including without limitation under the
        promissory notes listed on Schedule 11.1(m) hereto, (collectively, the
        Comerica Other Debt") or the maturity of any Comerica Other Debt shall
        have been accelerated, or any such Comerica Other Debt shall have been
        required to be prepaid prior to the stated maturity thereof, or any
        event shall have occurred that permits (or, with the giving of notice or
        the passage of time, or both, would permit) any holder or holders of
        such

                                            - 52 -
<PAGE>
        Comerica Other Debt or any Person acting on behalf of such holder or
        holders to accelerate the maturity thereof or require any prepayment.

                  (n) Any "Event of Default" or similar express occurrence shall
        exist under any of the EnSerCo Loan Documents.

        Section 11.2 REMEDIES. If any Event of Default shall occur and be
continuing, the Agent may (and if directed by Required Banks, shall) do any one
or more of the following:

                  (a) ACCELERATION. Declare an amount equal to the maximum
        aggregate amount that is or at any time thereafter may become available
        for drawing by the beneficiary under any outstanding Letters of Credit
        (whether or not any beneficiary shall have presented, or shall be
        entitled at such time to present, the drafts or other documents required
        to draw under such Letters of Credit) to be immediately due and payable,
        and declare all outstanding principal of and accrued and unpaid interest
        on the Notes and all other obligations of the Borrower under the Loan
        Documents immediately due and payable, and the same shall thereupon
        become immediately due and payable, without notice, demand, presentment,
        notice of dishonor, notice of acceleration, notice of intent to
        accelerate, protest, or other formalities of any kind, all of which are
        hereby expressly waived by the Borrower.

                  (b) TERMINATION OF COMMITMENTS. Terminate the Commitments and
        the Letter of Credit Commitment without notice to the Borrower.

                  (c) JUDGMENT. Reduce any claim to judgment.

                  (d) FORECLOSURE. Foreclose or otherwise enforce any Lien
        granted to the Agent for the benefit of itself and the Banks to secure
        payment and performance of the Obligations in accordance with the terms
        of the Loan Documents.

                  (e) RIGHTS. Exercise any and all rights and remedies afforded
        by the laws of the State of Texas or any other jurisdiction, by any of
        the Loan Documents, by equity, or otherwise.

Provided, however, that upon the occurrence of an Event of Default under
Subsection (d) or (e) of Section 11.1, the Commitments of all of the Banks shall
automatically terminate, and the outstanding principal of and accrued and unpaid
interest on the Notes and all other obligations of the Borrower under the Loan
Documents shall thereupon become immediately due and payable without notice,
demand, presentment, notice of dishonor, notice of acceleration, notice of
intent to accelerate, protest, or other formalities of any kind, all of which
are hereby expressly waived by the Borrower.

        Section 11.3 PERFORMANCE BY THE AGENT. If the Borrower shall fail to
perform any covenant or agreement in accordance with the terms of the Loan
Documents, the Agent may, at the direction of Required Banks, perform or attempt
to perform such covenant or agreement on behalf of the Borrower. In such event,
the Borrower shall, at the request of the Agent, promptly pay any

                                            - 53 -
<PAGE>
amount expended by the Agent or the Banks in connection with such performance or
attempted performance to the Agent at the Principal Office, together with
interest thereon at the Default Rate from and including the date of such
expenditure to but excluding the date such expenditure is paid in full.
Notwithstanding the foregoing, it is expressly agreed that neither the Agent nor
any Bank shall have any liability or responsibility for the performance of any
obligation of the Borrower under this Agreement or any of the other Loan
Documents.

                                          ARTICLE XII

                                           THE AGENT

<PAGE>
                  (h) To accept, execute, and deliver the Security Agreement and
        any other security documents as the secured party; and

                  (i) To take such other actions as may be requested by Required
Banks.

        Neither the Agent nor any of its Affiliates, officers, directors,
employees, attorneys, or agents shall be liable for any action taken or omitted
to be taken by any of them hereunder or otherwise in connection with this
Agreement or any of the other Loan Documents except for its or their own gross
negligence or willful misconduct. Without limiting the generality of the
preceding sentence, the Agent (i) may treat the payee of any Note as the holder
thereof until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent; (ii) shall
have no duties or responsibilities except those expressly set forth in this
Agreement and the other Loan Documents, and shall not by reason of this
Agreement or any other Loan Document be a trustee or fiduciary for any Bank;
(iii) shall not be required to initiate any litigation or collection proceedings
hereunder or under any other Loan Document except to the extent requested by
Required Banks; (iv) shall not be responsible to the Banks for any recitals,
statements, representations or warranties contained in this Agreement or any
other Loan Document, or any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Loan Document, or for the value, validity, effectiveness, enforceability, or
sufficiency of this Agreement or any other Loan Document or any other document
referred to or provided for herein or therein or for any failure by any Person
to perform any of its obligations hereunder or thereunder; (v) may consult with
legal counsel (including counsel for the Borrower), independent public
accountants, and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants, or experts; and (vi) shall incur no
liability under or in respect of any Loan Document by acting upon any notice,
consent, certificate, or other instrument or writing believed by it to be
genuine and signed or sent by the proper party or parties. As to any matters not
expressly provided for by this Agreement, the Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder in accordance with
instructions signed by Required Banks, and such instructions of Required Banks
and any action taken or failure to act pursuant thereto shall be binding on all
of the Banks; provided, however, that the Agent shall not be required to take
any action which exposes the Agent to personal liability or which is contrary to
this Agreement or any other Loan Document or applicable law.

        Section 12.2 RIGHTS OF AGENT AS A BANK. With respect to its Commitment,
the Advances made by it and the Note issued to it, Comerica Bank-Texas in its
capacity as a Bank hereunder shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not acting as the
Agent, and the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent in its individual capacity. The Agent and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to, act as trustee under indentures of, provide merchant
banking services to, and generally engage in any kind of business with the
Borrower, any of its Subsidiaries, any other Obligated Party, and any other
Person who may do business with or own securities of the Borrower, any
Subsidiary, or any other Obligated Party, all as if it were not acting as the
Agent and without any duty to account therefor to the Banks.

                                            - 55 -
<PAGE>
        Section 12.3 SHARING OF PAYMENTS, ETC. If any Bank shall obtain any
payment of any principal of or interest on any Advance made by it under this
Agreement or payment of any other obligation under the Loan Documents then owed
by the Borrower or any other Obligated Party to such Bank, whether voluntary,
involuntary, through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, in excess of its pro rata share,
such Bank shall promptly purchase from the other Banks participation in the
Advances held by them hereunder in such amounts, and make such other adjustments
from time to time as shall be necessary to cause such purchasing Bank to share
the excess payment ratably with each of the other Banks in accordance with its
pro rata portion thereof. To such end, all of the Banks shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if all or any portion of such excess payment is thereafter rescinded or must
otherwise be restored. The Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any Bank so purchasing a
participation in the Advances made by the other Banks may exercise all rights of
setoff, banker's lien, counterclaim, or similar rights with respect to such
participation as fully as if such Bank were a direct holder of Advances to the
Borrower in the amount of such participation. Nothing contained herein shall
require any Bank to exercise any such right or shall affect the right of any
Bank to exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Borrower.

        Section 12.4 INDEMNIFICATION. The Banks hereby agree to indemnify the
Agent from and hold the Agent harmless against (to the extent not reimbursed
under Sections 13.1 and 13.2, but without limiting the obligations of the
Borrower under Sections 13.1 and 13.2), ratably in accordance with their
respective Commitments, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, deficiencies, suits, costs, expenses (including
attorneys' fees), and disbursements of any kind or nature whatsoever which may
be imposed on, incurred by, or asserted against the Agent in any way relating to
or arising out of any of the Loan Documents or any action taken or omitted to be
taken by the Agent under or in respect of any of the Loan Documents; provided,
further, that no Bank shall be liable for any portion of the foregoing to the
extent caused by the Agent's gross negligence or willful misconduct. Without
limitation of the foregoing, it is the express intention of the Banks that the
Agent shall be indemnified hereunder from and held harmless against all of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
deficiencies, suits, costs, expenses (including attorneys' fees), and
disbursements of any kind or nature directly or indirectly arising out of or
resulting from the sole or contributory negligence of the Agent. Without
limiting any other provision of this Section, each Bank agrees to reimburse the
Agent promptly upon demand for its pro rata share (calculated on the basis of
the Commitments) of any and all out-of-pocket expenses (including attorneys'
fees) incurred by the Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings, or otherwise) of, or legal advice in
respect of rights or responsibilities under, the Loan Documents, to the extent
that the Agent is not reimbursed for such expenses by the Borrower.

        Section 12.5 INDEPENDENT CREDIT DECISIONS. Each Bank agrees that it has
independently and without reliance on the Agent or any other Bank, and based on
such documents and information as it has deemed appropriate, made its own credit
analysis of the Borrower and decision to enter into this Agreement and that it
will, independently and without reliance upon the Agent or any other

                                            - 56 -
<PAGE>
Bank, and based upon such documents and information as it shall deem appropriate
at the time, continue to make its own analysis and decisions in taking or not
taking action under this Agreement or any of the other Loan Documents. The Agent
shall not be required to keep itself informed as to the performance or
observance by the Borrower or any Obligated Party of this Agreement or any other
Loan Document or to inspect the properties or books of the Borrower or any
Obligated Party, Except for notices, reports and other documents and information
expressly required to be furnished to the Banks by the Agent hereunder or under
the other Loan Documents, the Agent shall not have any duty or responsibility to
provide any Bank with any credit or other financial information concerning the
affairs, financial condition or business of the Borrower or any Obligated Party
(or any of their Affiliates) which may come into the possession of the Agent or
any of its Affiliates.

        Section 12.6 SEVERAL COMMITMENTS. The Commitments and other obligations
of the Banks under this Agreement are several. The default by any Bank in making
an Advance in accordance with its Commitment shall not relieve the other Banks
of their obligations under this Agreement. In the event of any default by any
Bank in making any Advance, each nondefaulting Bank shall be obligated to make
its Advance but shall not be obligated to advance the amount which the
defaulting Bank was required to advance hereunder. In no event shall any Bank be
required to advance an amount or amounts which shall in the aggregate exceed
such Bank's Commitment. No Bank shall be responsible for any act or omission of
any other Bank.

        Section 12.7 SUCCESSOR AGENT. Subject to the appointment and acceptance
of a successor Agent as provided below may resign at any time by giving notice
thereof to the Banks and the Borrower and the Agent may be removed at any time
with or without cause by Required Banks. Upon any such resignation or removal,
Required Banks will have the right to appoint a successor Agent. If no successor
Agent shall have been so appointed by Required Banks and shall have accepted
such appointment within thirty (30) days after the retiring Agent's giving of
notice of resignation or the Required Banks' removal of the retiring Agent, then
the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which
shall be a commercial bank organized under the laws of the United States of
America or any State thereof and having combined capital and surplus of at least
One Hundred Million Dollars ($100,000,000). Upon the acceptance of its
appointment as successor Agent, such successor Agent shall thereupon succeed to
and become vested with all rights, powers, privileges, immunities, and duties of
the resigning or removed Agent, and the resigning or removed Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. After any Agent's resignation or removal as Agent, the
provisions of this Article XII shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was the
Agent. Notwithstanding the foregoing, Comerica may not be removed as the Agent
at the request of the Required Banks unless Comerica shall also simultaneously
be replaced as "Issuing Bank" hereunder pursuant to documentation in form and
substance satisfactory to Comerica.

                                         MISCELLANEOUS

        Section 13.1 EXPENSES. The Borrower hereby agrees to pay on demand: (a)
all costs and expenses of the Agent and the Banks in connection with the
preparation, negotiation, execution, and delivery of this Agreement and the
other Loan Documents and any and all amendments, modifications, renewals,
extensions, and supplements thereof and thereto, including, without limitation,
the fees and expenses of legal counsel for the Agent and the Banks, (b) all
costs and expenses of the Agent and the Banks in connection with any Default and
the enforcement of this Agreement or any other Loan Document, including, without
limitation, the fees and expenses of legal counsel for the Agent and the Banks,
(c) all transfer, stamp, documentary, or other similar taxes, assessments, or
charges levied by any Governmental Authority in respect of this Agreement or any
of the other Loan Documents, (d) all costs, expenses, assessments, and other
charges incurred in connection with any filing, registration, recording, or
perfection of any security interest or Lien contemplated by this Agreement or
any other Loan Document, and (e) all other costs and expenses incurred by the
Agent and the Banks in connection with this Agreement or any other Loan
Document, including, without limitation, all costs, expenses, and other charges
incurred in connection with obtaining any mortgagee title insurance policy,
survey, audit, or appraisal in respect of the Collateral.

        Section 13.2 INDEMNIFICATION. The Borrower shall indemnify the Agent and
each Bank and each Affiliate thereof and their respective officers, directors,
employees, attorneys, and agents from, and hold each of them harmless against,
any and all losses, liabilities, claims, damages, penalties, judgments,
disbursements, costs, and expenses (including attorneys' fees) to which any of
them may become subject which directly or indirectly arise from or relate to (a)
the negotiation, execution, delivery, performance, administration, or
enforcement of any of the Loan Documents, (b) any of the transactions
contemplated by the Loan Documents, (c) any breach by the Borrower of any
representation, warranty, covenant, or other agreement contained in any of the
Loan Documents, (d) the presence, Release, threatened Release, disposal,
removal, or cleanup of any Hazardous Material located on, about, within, or
affecting any of the properties or assets of the Borrower or any Subsidiary, or
(e) any investigation, litigation, or other proceeding, including, without
limitation, any threatened investigation, litigation, or other proceeding
relating to any of the foregoing. Without limiting any provision of this
Agreement or of any other Loan Document, it is the express intention of the
parties hereto that each Person to be indemnified under this Section shall be
indemnified from and held harmless against any and all losses, liabilities,
claims, damages, penalties, judgments, disbursements, costs, and expenses
(including attorneys' fees) arising out of or resulting from the sole or
contributory negligence of such Person.

        Section 13.3 LIMITATION OF LIABILITY. None of the Agent, any Bank, or
any Affiliate, officer, director, employee, attorney, or agent thereof shall
have any liability with respect to, and the Borrower hereby waives, releases,
and agrees not to sue any of them upon, any claim for any special, indirect,
incidental, or consequential damages suffered or incurred by the Borrower in
connection with, arising out of, or in any way related to, this Agreement or any
of the other Loan Documents, or any of the transactions contemplated by this
Agreement or any of the other Loan

                                            - 58 -
<PAGE>
Documents. The Borrower hereby waives, releases, and agrees not to sue the Agent
or any Bank or any of their respective Affiliates, officers, directors,
employees, attorneys, or agents for punitive damages in respect of any claim in
connection with, arising out of, or in any way related to, this Agreement or any
of the other Loan Documents, or any of the transactions contemplated by this
Agreement or any of the other Loan Documents.

        Section 13.4 NO DUTY. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by the Agent and the Banks shall
have the right to act exclusively in the interest of the Agent and the Banks and
shall have no duty of disclosure, duty of loyalty, duty of care, or other duty
or obligation of any type or nature whatsoever to the Borrower or any of the
Borrower's shareholders or any other Person.

        Section 13.5 NO FIDUCIARY RELATIONSHIP. The relationship between the
Borrower and each Bank is solely that of debtor and creditor, and neither the
Agent nor any Bank has any fiduciary or other special relationship with the
Borrower, and no term or condition of any of the Loan Documents shall be
construed so as to deem the relationship between the Borrower and any Bank to be
other than that of debtor and creditor.

        Section 13.6 EQUITABLE RELIEF. The Borrower recognizes that in the event
the Borrower fails to pay, perform, observe, or discharge any or all of the
Obligations, any remedy at law may prove to be inadequate relief to the Agent
and the Banks. The Borrower therefore agrees that the Agent and the Banks, if
the Agent or the Banks so request, shall be entitled to temporary and permanent
injunctive relief in any such case without the necessity of proving actual
damages.

        Section 13.7 NO WAIVER; CUMULATIVE REMEDIES. No failure on the part of
the Agent or any Bank to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power, or privilege under this Agreement
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power, or privilege under this Agreement preclude any other or
further exercise thereof or the exercise of any other right, power, or
privilege. The rights and remedies provided for in this Agreement and the other
Loan Documents are cumulative and not exclusive of any rights and remedies
provided by law.

        Section 13.8    SUCCESSORS AND ASSIGNS.

                  (a) This Agreement shall be binding upon and inure to the
        benefit of the parties hereto and their respective successors and
        assigns. The Borrower may not assign or transfer any of its rights or
        obligations hereunder without the prior written consent of the Agent and
        all of the Banks. Any Bank may sell participation to one or more banks
        or other institutions in or to all or a portion of its rights and
        obligations under this Agreement and the other Loan Documents
        (including, without limitation, all or a portion of its Commitments and
        the Advances owing to it); provided, however, that (i) such Bank's
        obligations under this Agreement and the other Loan Documents
        (including, without limitation, its Commitment) shall remain unchanged,
        (ii) such Bank shall remain solely responsible to the Borrower for the
        performance of such obligations, (iii) such Bank shall remain the holder
        of its Note for all purposes of this Agreement, (iv) the Borrower shall
        continue to deal solely and directly

                                            - 59 -
<PAGE>
        with such Bank in connection with such Bank's rights and obligations
        under this Agreement and the other Loan Documents, and (v) such Bank
        shall not sell a participation that conveys to the participant the right
        to vote or give or withhold consents under this Agreement or any other
        Loan Document, other than the right to vote upon or consent to (A) any
        increase of such Bank's Commitment, (B) any reduction of the principal
        amount of, or interest to be paid on, the Advances of such Bank, (C) any
        reduction of any commitment fee or other amount payable to such Bank
        under any Loan Document, or (D) any postponement of any date for the
        payment of any amount payable in respect of the Advances of such Bank.

                  (b) The Borrower and each of the Banks agree that any Bank
        (the "Assigning Bank") may at any time assign to one or more Eligible
        Assignees all, or a proportionate part of all, of its rights and
        obligations under this Agreement and the other Loan Documents
        (including, without limitation, its Commitment and Advances) (each an
        "Assignee"); provided, however, that (i) each such assignment shall be
        of a consistent, and not a varying, percentage of all of the assigning
        Bank's rights and obligations under this Agreement and the other Loan
        Documents, (ii) except in the case of an assignment of all of a Bank's
        rights and obligations under this Agreement and the other Loan
        Documents, the amount of the Commitment of the assigning Bank being
        assigned pursuant to each assignment (determined as of the date of the
        Assignment Acceptance with respect to such assignment) shall in no event
        be less than $10,000,000, and (iii) the parties to each such assignment
        shall execute and deliver to the Agent for its acceptance and recording
        in the Register (as defined below), an Assignment and Acceptance,
        together with the Note subject to such assignment, and a processing and
        recordation fee of $3,000. Upon such execution, delivery, acceptance,
        and recording, from and after the effective date specified in each
        Assignment and Acceptance, which effective date shall be at least five
        (5) Business Days after the execution thereof, or, if so specified in
        such Assignment and Acceptance, the date of acceptance thereof by the
        Agent, (x) the assignee thereunder shall be a party hereto as a "Bank"
        and, to the extent that rights and obligations hereunder have been
        assigned to it pursuant to such Assignment and Acceptance, have the
        rights and obligations of a Bank hereunder and under the Loan Documents
        and (y) the Bank that is an assignor thereunder shall, to the extent
        that rights and obligations hereunder have been assigned by it pursuant
        to such Assignment and Acceptance, relinquish its rights and be released
        from its obligations under this Agreement and the other Loan Documents
        (and, in the case of an Assignment and Acceptance covering all or the
        remaining portion of a Bank's rights and obligations under the Loan
        Documents, such Bank shall cease to be a party thereto).

                  (c) By executing and delivering an Assignment and Acceptance,
        the Bank that is an assignor thereunder and the assignee thereunder
        confirm to and agree with each other and the other parties hereto as
        follows: (i) other than as provided in such Assignment and Acceptance,
        such assigning Bank makes no representation or warranty and assumes no
        responsibility with respect to any statements, warranties, or
        representations made in or in connection with the Loan Documents or the
        execution, legality, validity, and enforceability, genuineness,
        sufficiency, or value of the Loan Documents or any other instrument or
        document furnished pursuant thereto; (ii) such assigning Bank makes no
        representation or warranty and assumes no responsibility with respect to
        the financial condition of the

                                            - 60 -
<PAGE>
        Borrower or any Obligated Party or the performance or observance by the
        Borrower or any Obligated Party of its obligations under the Loan
        Documents; (iii) such assignee confirms that it has received a copy of
        the other Loan Documents, together with copies of the financial
        statements referred to in Section 7.2 and such other documents and
        information as it has deemed appropriate to make its own credit analysis
        and decision to enter into such Assignment and Acceptance; (iv) such
        assignee will, independently and without reliance upon the Agent or such
        assignor and based on such documents and information as it shall deem
        appropriate at the time, continue to make its own credit decisions in
        taking or not taking action under this Agreement and the other Loan
        Documents; (v) such assignee confirms that it is an Eligible Assignee;
        (vi) such assignee appoints and authorizes the Agent to take such action
        as agent on its behalf and exercise such powers under the Loan Documents
        as are delegated to the Agent by the terms thereof, together with such
        powers as are reasonably incidental thereto; and (vii) such assignee
        agrees that it will perform in accordance with their terms all of the
        obligations which by the terms of the Loan Documents are required to be
        performed by it as a Bank.

                  (d) The Agent shall maintain at its Principal Office a copy of
        each Assignment and Acceptance delivered to and accepted by it and a
        register for the recordation of the names and addresses of the Banks and
        the Commitment of, and principal amount of the Advances owing to, each
        Bank from time to time (the "REGISTER"). The entries in the Register
        shall be conclusive and binding for all purposes, absent manifest error,
        and the Borrower, the Agent, and the Banks may treat each Person whose
        name is recorded in the Register as a Bank hereunder for all purposes
        under the Loan Documents. The Register shall be available for inspection
        by the Borrower or any Bank at any reasonable time and from time to time
        upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
        by an assigning Bank and assignee representing that it is an Eligible
        Assignee, together with any Note subject to such assignment, the Agent
        shall, if such Assignment and Acceptance has been completed and is in
        substantially the form of Exhibit "G" hereto, (i) accept such Assignment
        and Acceptance, (ii) record the information contained therein in the
        Register, and (iii) give prompt written notice thereof to the Borrower.
        Within five (5) Business Days after its receipt of such notice, the
        Borrower, at its expense, shall execute and deliver to the Agent in
        exchange for the surrendered Note a new Note to the order of such
        Eligible Assignee in an amount equal to the Commitment assumed by it
        pursuant to such Assignment and Acceptance and, if the assigning Bank
        has retained a Commitment, a new Note to the order of the assigning Bank
        in an amount equal to the Commitment retained by it hereunder (each such
        promissory note shall constitute a "Note" for purposes of the Loan
        Documents). Such new Notes shall be in an aggregate principal amount of
        the surrendered Note, shall be dated the effective date of such
        Assignment and Acceptance, and shall otherwise be in substantially the
        form of Exhibit "A" hereto.

                  (f) Any Bank may, in connection with any assignment or
        participation or proposed assignment or participation pursuant to this
        Section, disclose to the assignee or

                                            - 61 -
<PAGE>
        participant or proposed assignee or participant, any information
        relating to the Borrower or its Subsidiaries furnished to such Bank by
        or on behalf of the Borrower or its Subsidiaries.

        Section 13.9 SURVIVAL. All representations and warranties made in this
Agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by the Agent or any Bank or any closing shall affect the
representations and warranties or the right of the Agent or any Bank to rely
upon them. Without prejudice to the survival of any other obligation of the
Borrower hereunder, the obligations of the Borrower under Article IV and
Sections 13.1 and 13.2 shall survive repayment of the Notes and termination of
the Commitments.

        Section 13.10 ENTIRE AGREEMENT. THIS AGREEMENT, THE NOTES, AND THE OTHER
LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE
PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS,
REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE
SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS THE PARTIES
HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO.

        Section 13.11 AMENDMENTS, ETC. No amendment or waiver of any provision
of this Agreement, the Notes, or any other Loan Document to which the Borrower
is a party, nor any consent to any departure by the Borrower therefrom, shall in
any event be effective unless the same shall be agreed or consented to by
Required Banks and the Borrower, and each such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, that no amendment, waiver, or consent shall, unless in writing
and signed by all of the Banks and the Borrower, do any of the following: (a)
increase Commitments of the Banks or subject the Banks to any additional
obligations; (b) reduce the principal of, or interest on, the Notes or any fees
or other amounts payable hereunder; (c) postpone any date fixed for any payment
of principal of, or interest on, the Notes or any fees or other amounts payable
hereunder; (d) waive any of the conditions specified in Article VI; (e) change
the percentage of the Commitments or of the aggregate unpaid principal amount of
the Notes or the number of Banks which shall be required for the Banks or any of
them to take any action under this Agreement; (f) change any provision contained
in this Section 13.1 1; or (g) release any Collateral. Notwithstanding anything
to the contrary contained in this Section, no amendment, waiver, or consent
shall be made with respect to Article XII hereof without the prior written
consent of the Agent.

        Section 13.12 MAXIMUM INTEREST RATE. No provision of this Agreement or
of any other Loan Document shall require the payment or the collection of
interest in excess of the maximum amount permitted by applicable law. If any
excess of interest in such respect is hereby provided for, or shall be
adjudicated to be so provided, in any Loan Document or otherwise in connection
with this loan transaction, the provisions of this Section shall govern and
prevail and neither the Borrower nor the sureties, guarantors, successors, or
assigns of the Borrower shall be obligated to pay the

                                            - 62 -
<PAGE>
excess amount of such interest or any other excess sum paid for the use,
forbearance, or detention of sums loaned pursuant hereto. In the event any Bank
ever receives, collects, or applies as interest any such sum, such amount which
would be in excess of the maximum amount permitted by applicable law shall be
applied as a payment and reduction of the principal of the indebtedness
evidenced by the Notes; and, if the principal of the Notes has been paid in
full, any remaining excess shall forthwith be paid to the Borrower. In
determining whether or not the interest paid or payable exceeds the Maximum
Rate, the Borrower and each Bank shall, to the extent permitted by applicable
law, (a) characterize any non-principal payment as an expense, fee, or premium
rather than as interest, (b) exclude voluntary prepayments and the effects
thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal
parts the total amount of interest throughout the entire contemplated term of
the indebtedness evidenced by the Notes so that interest for the entire term
does not exceed the Maximum Rate.

        Section 13.13 NOTICES. All notices and other communications provided for
in this Agreement and the other Loan Documents to which the Borrower is a party
shall be given or made by telex, telegraph, telecopy, cable, or in writing and
telexed, telecopied, telegraphed, cabled, mailed by certified mail return
receipt requested, or delivered to the intended recipient at the "Address for
Notices" specified below its name on the signature pages hereof; or, as to any
party at such other address as shall be designated by such party in a notice to
each other party given in accordance with this Section. Except as otherwise
provided in this Agreement, all such communications shall be deemed to have been
duly given when transmitted by telex or telecopy, subject to telephone
confirmation of receipt, or delivered to the telegraph or cable office, subject
to telephone confirmation of receipt, or when personally delivered or, in the
case of a mailed notice, when duly deposited in the mails, in each case given or
addressed as aforesaid; provided, however, notices to the Agent pursuant to
Article II shall not be effective until received by the Agent.

        Section 13.14 GOVERNING LAW; VENUE; SERVICE OF PROCESS. This Agreement
shall be governed by and construed in accordance with the laws of the State of
Texas and the applicable laws of the United States of America (without reference
to principles of conflicts of laws). This Agreement has been entered into in
Dallas County, Texas, and it shall be performable for all purposes in Dallas
County, Texas. Any action or proceeding against the Borrower under or in
connection with any of the Loan Documents may be brought in any state or federal
court in Dallas County, Texas. The Borrower hereby irrevocably (a) submits to
the nonexclusive jurisdiction of such courts, and (b) waives any objection it
may now or hereafter have as to the venue of any such action or proceeding
brought in any such court or that any such court is an inconvenient forum. The
Borrower agrees that service of process upon it may be made by certified or
registered mail, return receipt requested, at its address specified or
determined in accordance with the provisions of Section 13.13. Nothing herein or
in any of the other Loan Documents shall affect the right of the Agent or any
Bank to serve process in any other manner permitted by law or shall limit the
right of the Agent or any Bank to bring any action or proceeding against the
Borrower or with respect to any of its property in courts in other
jurisdictions. Any action or proceeding by the Borrower against the Agent or any
Bank shall be brought only in a court located in Dallas County, Texas.

        Section 13.15 COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

        Section 13.16 SEVERABILITY. Any provision of this Agreement held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

        Section 13.17 HEADINGS. The headings, captions, and arrangements used in
this Agreement are for convenience only and shall not affect the interpretation
of this Agreement.

        Section 13.18 NON-APPLICATION OF CHAPTER 346 OF TEXAS FINANCE CODE. The
provisions of Chapter 346 of the Texas Finance Code are specifically declared by
the parties hereto not to be applicable to this Agreement or any of the other
Loan Documents or to the transactions contemplated hereby.

        Section 13.19 CONSTRUCTION. The Borrower, the Agent, and each Bank
acknowledges that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review this Agreement and the
other Loan Documents with its legal counsel and that this Agreement and the
other Loan Documents shall be construed as if jointly drafted by the parties
hereto.

        Section 13.20 INDEPENDENCE OF COVENANTS. All covenants hereunder shall
be given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or be otherwise within the limitations of, another covenant shall
not avoid the occurrence of a Default if such action is taken or such condition
exists.

        Section 13.21 WAIVER JURY TRIAL. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH THE PARTIES HERETO HEREBY IRREVOCABLY AND EXPRESSLY WAIVES
ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER
BASED UPON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OR RELATING TO ANY THE LOAN
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS THE AGENT OR
ANY BANK IN THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.

                                                        Lease Agreement No. 9835

                               COMERICA LEASING CORPORATION

                                      LEASE SCHEDULE

1. DESCRIPTION OF LEASE: Lease Agreement dated JUNE 30, 1998 , by and between
COMERICA LEASING CORPORATION (herein "CLC") as Lessor, and INDUSTRIAL HOLDINGS,
INC. AND BEAIRD INDUSTRIES, INC. CO-LESSEES as Lessee (herein called "Lease
Agreement").

2.  DESCRIPTION OF EQUIPMENT:

                      "As further described on attached Exhibit 'A'"

3.  LOCATION: The equipment described above shall be located at 601 BENTON KELLY
STREET, SHREVEPORT, LA 71106-7198 .

4. TERM; RENTAL: The Term of the Lease Agreement for the Equipment described in
this Schedule shall be in accordance with the provisions of the Lease Agreement
and shall continue until all rental payments are fully paid. Lessee hereby
agrees to pay CLC as monthly rent for the Equipment, an amount equal to
$142,857.14 per month (to be applied towards principal), plus interest in
arrears as may be adjusted and re-calculated pursuant to an Adjustment Event,
plus any applicable sales and/or use taxes, commencing on JULY 30, 1998 and on
the 30th calendar day for 59 months, followed by a final principal installment
of $3,571,428.74 plus interest until fully paid. The rental payments shall be
remitted to CLC at Drawer 67-042, Detroit, Michigan 48267, unless CLC specifies
otherwise in writing.

Lessee and CLC expressly acknowledge and agree that the amount of Lessees
monthly rental payment obligation under the Lease Agreement is dependent upon
the Eurodollar-based Rate then in effect for the applicable monthly rental
period ("Billing Period") and that the 30 -day Eurodollar-based Rate as of for
JUNE 30, 1998 the first monthly Billing Period is 5.625%. The spread over the
Euro-Dollar based rate shall be 2.75%.

The amount from time-to-time outstanding under the Lease Agreement, and the
amount of any required monthly rental payment shall be noted on CLC's books and
records, which shall be conclusive evidence thereof, absent manifest error;
provided, however, any failure by CLC to make any such notation, or any error in
any such notation, shall not relieve Lessee of its obligations to repay CLC all
amounts payable by Lessee to CLC under or pursuant to the Lease Agreement in
accordance with the terms hereof.

Lessee may elect from time-to-time as specifically provided herein to designate
the "30"; "60"; "90"; "180" or "360" day Eurodollar-based Rate ("Fixed Period")
as the applicable rate to be used in the calculation of Lessees monthly payment
for all amounts outstanding under this Lease Schedule by delivering to CLC, by
11:00 a.m. (Detroit, Michigan time), two (2) Business Days prior to the
expiration of the current Fixed Period, a Notice of Change in Fixed Period
Election executed by a duly authorized officer of Lessee. Until written
notification by Lessee to CLC to the contrary, the Eurodollar-based Rate Fixed
Period last chosen by Lessee shall be used by CLC for all future calculations.

For the purposes of this Lease Agreement, the following terms will have the
following meanings:

    "Adjustment Event" shall mean a change up or down in the Eurodollar-based
    Rate as of the date which is two (2) Business Days prior to the expiration
    of the current Fixed Period, from the Eurodollar-based Rate then in effect
    pursuant to the terms hereof.

    "Business Day" shall mean any day other than a Saturday, Sunday or holiday
    on which CLC is open for all or substantially all of its domestic and
    international commercial business in Detroit, Michigan.

    "Eurodollar-based Rate" shall mean the quotient of:

    (a) the per annum interest rate at which Comerica Bank's Eurodollar Lending
    Office located in the Grand Cayman Islands, British West Indies, or such
    other branch of Comerica Bank as it may hereinafter designate, offers
    deposits to prime banks in the eurodollar market in an amount comparable to
    all amounts outstanding under this Lease Schedule and for a period equal to
    the respective Fixed Period chosen by Lessee at approximately 11:00 a.m.,
    Detroit, Michigan time, two (2) Business Days prior to the expiration of the
    current Fixed Period;

    divided by

    (b) a percentage equal to 100% minus the maximum rate on such date at which
    Comerica Bank is required to maintain reserves on "Euro- currency
    Liabilities" as defined in and pursuant to Regulation D of the Board of
    Governors of the Federal Reserve System or, if such regulation or definition
    is modified, and as long as Comerica Bank is required to maintain reserves
    against a category of liabilities which includes eurodollar deposits or
    includes a category of assets which includes eurodollar loans, the rate at
    which such reserves are required to be maintained on such category.

5. INSURANCE: Lessee agrees to maintain adequate property damage insurance in
accordance with the terms of the Lease Agreement, but in any event not less than
the sum of the payments due, protecting CLCB as a loss payee. The minimum amount
indicated above shall NOT be construed to imply such amount will be or is
adequate, but rather as a minimum amount.

6. UCC 2A: In accordance with Section 2A of the Michigan Uniform Commercial Code
(MCLA Section 440.3101 et seq.) ("UCC") Lessee acknowledges either (a) that
Lessee has reviewed and approved any written Supply Contract (as defined by UCC
Section 2A-103(I)(y)) covering the Equipment purchased from the "Supplier" (as
defined by UCC Section 2A-103(I)(x)) thereof for lease to Lessee or (b) that
Lessor has informed or advised Lessee, in writing, either previously or by this
Lease Schedule of the following: (I) the identity of the supplier; (ii) that the
Lessee may have rights under the Supply Contract; and (iii) that the Lessee may
contact the Supplier for a description of any such rights lessee may have under
the Supply Contract.

                                                           Lessee's Initials:

7. PREPAYMENT: No Prepayment is allowed until after the twelfth month
anniversary. Prepayment in full is allowed on any regular lease installment date
after the twelfth month anniversary. After the twelfth month anniversary and
before the eighteenth month anniversary, Lessee will pay as liquidated damages,
and not as penalty, a .5% prepayment premium on the remaining principal balance.
No prepayment premiums will be assessed for full prepayment after the eighteenth
month anniversary.

The foregoing is hereby approved and agreed to by the undersigned as a Schedule
to and a part of the Lease Agreement, the provisions of which are hereby
incorporated herein by reference and which shall govern, notwithstanding
anything contrary or inconsistent herein.

                                    THE LOAN

      Section 2.1 THE LOAN. The Lender agrees, on the terms and conditions set
forth in this Agreement and for the purposes set forth in Section 5.1, to make a
single loan ("Loan") to the Borrower in the principal amount of the Loan
Commitment. The Loan is not revolving, therefore, the Borrower may not reborrow
amounts prepaid under the Loan. The indebtedness of the Borrower to the Lender
resulting from the Loan shall be evidenced by the Note.

      Section 2.2 PREPAYMENT.

            (a) The Borrower may from time to time voluntarily prepay all or a
part of the outstanding principal amount of the Loan pursuant to written notice
given by the Borrower to the Lender not less than five Business Days prior to
the date of prepayment. Each such notice shall specify the principal amount
which shall be prepaid and the date of the prepayment, and shall be irrevocable
and binding on the Borrower. Partial prepayments of the Loan must be made in a
minimum amount of $1,000,000 and in integral multiples of $100,000; provided
that unless such proposed prepayment prepays the entire outstanding principal
amount of the Loan, no proposed prepayment shall be permitted if the aggregate
outstanding principal amount of the Loan after giving effect to such proposed
prepayment would be less than $1,000,000 and further provided that the Borrower
must comply with Section 2.5(b). For each such notice given by the Borrower, the
Borrower shall prepay the Loan in the specified amount on the specified date as
set forth in such notice. The Borrower shall have no right to prepay any
principal amount of the Loan except as provided in this Section 2.2. Each
prepayment of principal pursuant to this Section 2.2 shall be accompanied by
payment of all accrued but unpaid interest on the principal amount prepaid and
any payments required under Section 2.2(b) and Section 2.6.

      (b) With each prepayment of the Loan under Section 2.2(b) or upon any
acceleration of the Loan under Section 7.2, the Borrower shall pay to the Lender
the applicable premium for the applicable period specified in the table below:

            PERIOD                              PREMIUM

      Closing Date - December 31, 1998   Make-Whole Amount
      January 1, 1999 - June 30, 1999    1.00% of principal amount of prepayment
      July 1, 1999 and thereafter        no prepayment premium is owed

If a Make-Whole Amount will be due, the Lender shall provide the Borrower with a
certificate stating the amount and basis of calculation of the Make-Whole
Amount, and such certificate shall be conclusive and binding, absent manifest
error. For the purposes of this Agreement, the following terms shall have the
following meanings:

      "Make-Whole Amount" means the discounted present value of the Prepaid
      Scheduled Interest Payments determined by discounting the Prepaid
      Scheduled Interest Payments from their

                                       11
<PAGE>
      respective scheduled due dates to the Prepayment Date in accordance with
      accepted financial practice at a discount rate equal to the Discount Rate.

      "Prepaid Principal" means, with respect to any prepayment, the principal
      amount of the principal being prepaid.

      "Prepaid Scheduled Interest Payments" means each scheduled payment of
      interest on the Prepaid Principal after the Prepayment Date that would
      have been due on or before June 30, 1999, in accordance with this
      Agreement assuming that the Prepaid Principal bears interest at a rate be
      annum equal to the Applicable Margin and no prepayment of the Prepaid
      Principal had occurred.

      "Prepayment Date" means, with respect to any prepayment, the date on which
      the prepayment is made or deemed made.

      "Discount Rate" means, (i) the yields reported, as of 11:00 A.M. (Houston,
      Texas time) on the first Business Day preceding the Prepayment Date, on
      the display designated as "Page USD" on the Dow Jones Market Service (or
      such other display as may replace Page USD on the Dow Jones Market
      Service) for actively traded U.S. Treasury securities having a maturity
      equal to one year or (ii) if such yields are not reported as of such time
      or the yields reported as of such time are not ascertainable, the Treasury
      Constant Maturity Series Yields reported, for the latest day for which
      such yields have been so reported as of the first Business Day preceding
      the Prepayment Date, in Federal Reserve Statistical Release H.15 (519) (or
      any comparable successor publication) for actively traded U.S. Treasury
      securities having a constant maturity equal to one year.

      Section 2.3 REPAYMENT. The Borrower shall repay to the Lender the
outstanding principal amount of the Loan on the Maturity Date.

      Section 2.4 FEES. The Borrower shall pay to the Lender a structuring fee
equal to $225,000, payable upon the Borrower's and the Lender's execution of
this Agreement. The Lender acknowledges that the $50,000 working fee previously
paid by the Borrower to the Lender shall be applied to the structuring fee.

      Section 2.5 INTEREST.

            (a) ELECTION OF INTEREST RATE BASIS. The Borrower may select the
interest rate basis for the outstanding principal amount of the Loan in
accordance with the terms of this Section 2.5(a), except that the Loan initially
shall consist of only a Base Rate Tranche:

                  (i) With respect to any Tranche, the Borrower may continue or
convert any portion of any LIBOR Tranche or Base Rate Tranche to form new LIBOR
Tranches or Base Rate Tranches in accordance with this paragraph. Each such
continuation or conversion shall be made pursuant to a Continuation/Conversion
Request given by the Borrower to the Lender in writing or by telecopy not later
than 11:00 a.m. (Houston, Texas, time) on the fourth Business Day before the
date

                                       12
<PAGE>
of the proposed continuation or conversion. Each Continuation/Conversion Request
shall be fully completed and shall specify the information required therein, and
shall be irrevocable and binding on the Borrower. In the case of any
continuation or conversion into LIBOR Tranches, upon the Borrower's request, the
Lender shall notify the Borrower of the applicable interest rate. Continuations
and conversions involving LIBOR Tranches shall be made in integral multiples of
the Minimum LIBOR Tranche Multiple. No continuation or conversion shall be
permitted if such continuation or conversion would cause the outstanding
principal amount of any LIBOR Tranche which would remain outstanding under the
Loan to be less than the Minimum LIBOR Tranche Amount. At no time shall there be
more than five separate LIBOR Tranches outstanding. Any conversion of an
existing LIBOR Tranche is subject to Section 2.6. Subject to the satisfaction of
all applicable conditions precedent, the Lender shall before close of business
on the date requested by the Borrower for the continuation or conversion, make
such continuation or conversion.

                  (ii) At the end of the Interest Period for any LIBOR Tranche
if the Borrower has not continued or converted such LIBOR Tranche into new
Tranches as provided for in paragraph (i) above, the Borrower shall be deemed to
have continued such LIBOR Tranche as a Base Rate Tranche. Each Base Rate Tranche
shall continue as a Base Rate Tranche unless the Borrower converts such Base
Rate Tranche as provided for in paragraph (i) above.

            (b) PAYMENTS ON LIBOR TRANCHES. With respect to payments made on the
outstanding principal of the Loan, subject to the other requirements in this
Agreement, the Borrower may allocate the payments among the Tranches comprising
the Loan. Unless required by mandatory payments, partial prepayments involving
LIBOR Tranches must be made in multiples of the Minimum LIBOR Tranche Multiple
and no partial prepayment may be made if the prepayment would cause the
outstanding principal amount of any LIBOR Tranche to be less than the Minimum
LIBOR Tranche Amount. No voluntary prepayment of any LIBOR Tranche may be made
unless the required notice is provided by 11:00 a.m. (Houston, Texas, time) on
the fifth Business Day before the date of the proposed prepayment.

            (c) INTEREST ON LIBOR TRANCHES. Each LIBOR Tranche shall bear
interest during its Interest Period at a per annum interest rate equal to the
sum of the LIBOR for such LIBOR Tranche plus the Applicable Margin. The Borrower
shall pay to the Lender all accrued but unpaid interest on each outstanding
LIBOR Tranche (i) on the last day of such LIBOR Tranche's Interest Period and
(ii) on the Maturity Date.

            (d) INTEREST ON BASE RATE TRANCHES. Each Base Rate Tranche shall
bear interest at a per annum interest rate equal to the Base Rate in effect from
time to time plus the Applicable Margin. The Borrower shall pay to the Lender
all accrued but unpaid interest on each outstanding Base Rate Tranche (i)
beginning September 30, 1998, and on each Quarterly Date thereafter and (ii) on
the Maturity Date.

            (e) PREVENTION OF USURY.

                  (i) If the effective rate of interest contracted for by the
Lender with the Borrower under the Loan Documents, including the stated rates of
interest contracted for hereunder

                                       13
<PAGE>
and any other amounts contracted for under the Loan Documents which are deemed
to be interest, at any time exceeds the Highest Lawful Rate, then the
outstanding principal amount of the loans made by the Lender to the Borrower
hereunder shall bear interest at a rate which would make the effective rate of
interest on the loans made by the Lender to the Borrower under the Loan
Documents equal the Highest Lawful Rate until the difference between the amounts
which would have been due by the Borrower to the Lender at the stated rates and
the amounts which were due by the Borrower to the Lender at the Highest Lawful
Rate (such difference being the "Lost Interest") has been recaptured by the
Lender. If, when the loans made hereunder are repaid in full, the Lost Interest
has not been fully recaptured by the Lender pursuant to the preceding sentence,
then, to the extent permitted by law, the interest rates charged by the Lender
to the Borrower under Section 2.5 shall be retroactively increased such that the
effective rate of interest on the loans made by the Lender to the Borrower under
the Loan Documents was at the Highest Lawful Rate since the effectiveness of
this Agreement to the extent necessary to recapture the Lost Interest not
recaptured pursuant to the preceding sentence and, to the extent allowed by law,
the Borrower shall pay to the Lender the amount of the Lost Interest remaining
to be recaptured by the Lender.

                  (ii) In calculating all sums paid or agreed to be paid to the
Lender by the Borrower for the use, forbearance, or detention of money under the
Loan Documents, such amounts shall, to the extent permitted by applicable law,
be amortized, prorated, allocated, and spread in equal parts throughout the term
of the Loan Documents.

                  (iii) NOTWITHSTANDING THE FOREGOING OR ANY OTHER TERM
IN THIS AGREEMENT AND THE LOAN DOCUMENTS TO THE CONTRARY, it is the intention

of the Lender and the Borrower to conform strictly to any applicable usury laws.
Accordingly, if the Lender contracts for, charges, or receives any consideration
from the Borrower which constitutes interest in excess of the Highest Lawful
Rate, then any such excess shall be canceled automatically and, if previously
paid, shall at the Lender's option be applied to the outstanding amount of the
loans made hereunder by the Lender to the Borrower or be refunded to the
Borrower.

      Section 2.6 BREAKAGE COSTS. If (i) any payment of principal on or any
conversion of any LIBOR Tranche is made on any date other than the last day of
the Interest Period for such LIBOR Tranche, whether as a result of any voluntary
or mandatory prepayment, any acceleration of maturity, or any other cause, (ii)
any payment of principal on any LIBOR Tranche is not made when due, or (iii) any
LIBOR Tranche is not borrowed, converted, or prepaid in accordance with the
respective notice thereof provided by the Borrower to the Lender, whether as a
result of any failure to meet any applicable conditions precedent for borrowing,
conversion, or prepayment, the cancellation of any request for borrowing,
conversion, or prepayment, the failure of the Borrower to provide the respective
notice of borrowing, conversion, or prepayment, or any other cause not specified
above which is created by the Borrower, then the Borrower shall pay to the
Lender upon demand any amounts required to compensate the Lender for any losses,
costs, or expenses, including administrative expenses, but excluding lost
profits, which are allocable to such action, including losses, costs, and
expenses related to the liquidation or reinvestment of funds acquired or
designated by the Lender to fund or maintain such LIBOR Tranche or related to
the reacquisition or redesignation of funds by the Lender to fund or maintain
such LIBOR Tranche following any liquidation or reinvestment of such funds
caused by such action. A certificate as to the amount of such loss, cost, or
expense detailing the

                                       14
<PAGE>
calculation thereof submitted by the Lender to the Borrower shall be conclusive
and binding for all purposes, absent manifest error.

Loan or obtaining funds for the making, funding, or maintaining of the Loan or
any Tranche in the relevant interbank market, including in each case any

Board whether for emergency, marginal, supplemental, or other reserves, then the
Borrower shall pay to the Lender upon demand any amounts required to compensate
the Lender for such increased costs, such amounts being due and payable upon
demand by the Lender. A certificate as to the cause and amount of such increased
cost detailing the calculation of such cost and certifying that the Lender
customarily charges such amounts to its other customers in similar circumstances
submitted by the Lender to the Borrower shall be conclusive and binding for all
purposes, absent manifest error.

            (b) CAPITAL ADEQUACY. If, due to either (i) any introduction of,
change in, or change in the interpretation of any law or regulation after the
date of this Agreement or (ii) compliance with any guideline or request from any
central bank or other governmental authority having appropriate jurisdiction

there shall be any increase in the capital requirements of the Lender or its
parent or holding company allocable to (x) committing to make the loan or
making, funding, or maintaining of the Loan or any Tranche, as such capital
requirements are allocated by the Lender, then the Borrower shall pay to the
Lender upon demand any amounts required to compensate the Lender or its parent
or holding company for such increase in costs (including an amount equal to any
reduction in the rate of return on assets or equity of the Lender or its parent
or holding company), such amounts being due and payable upon demand by the
Lender. A certificate as to the cause and amount of such increased cost
detailing the calculation of such cost and certifying that the Lender
customarily charges such amounts to its other customers in similar circumstances
submitted by the Lender to the Borrower shall be conclusive and binding for all
purposes, absent manifest error. The Lender may not make any claim for
compensation under this Section 2.7(b) for increased costs incurred before six
months prior to the delivery of any such certificate.

      Section 2.8 ILLEGALITY. Notwithstanding any other provision in this
Agreement, if it becomes unlawful for the Lender to obtain deposits or other
funds for making or funding any LIBOR Tranche in the relevant interbank market,
the Lender shall so notify the Borrower and the Lender's commitment to create
LIBOR Tranches shall be suspended until such condition has passed, all LIBOR
Tranches applicable to the Lender shall be converted to Base Rate Tranches as of
the end of each applicable Interest Period or earlier if necessary, and all

      Section 2.9 MARKET FAILURE. Notwithstanding any other provision in this
Agreement, if the Lender determines that: (a) quotations of interest rates for
the relevant deposits referred to in the definition of "LIBOR" are not being
provided in the relevant amounts, or maturities for purposes of determining the
rate of interest referred to in the definition of "LIBOR" or (b) the relevant
rates of interest referred to in the definition of "LIBOR" which are used as the
basis to determine the rate of interest for LIBOR Tranches are not likely to
adequately cover the cost to the Lender of making or maintaining any LIBOR
Tranche, then if the Lender so notifies the Borrower, the commitment of the
Lender to create LIBOR Tranches shall be suspended until such condition has
passed, all LIBOR Tranches shall be converted to Base Rate Tranches as of the
end of each applicable Interest Period, and all subsequent requests for LIBOR
Tranches shall be deemed to be requests for Base Rate Tranches.

      Section 2.10PAYMENTS; COMPUTATIONS.

            (a) The Lender shall retain records of the advancing of the Loan and
all payments of principal and interest thereon, but the failure of the Lender to
do so shall not relieve the Borrower of its liability for the payment thereof.
Such records shall be conclusive and binding regarding the outstanding principal
amount of the Loan and the accrued but unpaid interest thereon, absent manifest
error.

            (b) All payments made by or on behalf of the Borrower under this
Agreement and the Note shall be made by wire transfer in immediately available
funds before 11:00 a.m. (Houston, Texas Time) on the date such payment is
required to be made to an account located in New York directed by the Lender
from time to time in writing. Any payment received by the Lender after such time
shall be considered for all purposes, including the calculation of interest, as
having been made on the next following Business Day. All payments required to be
made by the Borrower shall be made without any counterclaim, offset, abatement,
withholding, or reduction whatsoever.

            (c) Whenever any payment under this Agreement or the Note shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day. Such extension of time shall be included in
the computation of the payment of interest, fees, or such other amount due on
the outstanding amount. If the time for payment for an amount payable is not
specified under this Agreement or the Note, the payment shall be due and payable
on the date which is five (5) Business Days after the date the Lender demands
payment therefor.

            (d) If the method of computing any interest or fees is not otherwise
set forth in this Agreement or the Note, such interest shall be computed based
upon the applicable per annum rate set forth in this Agreement or the Note
computed on the basis of a 365/366 day year, as applicable, for the actual
number of days elapsed, except for interest rates bases on LIBOR which shall be
computed on the basis of a 360 day year for the actual number of days elapsed.

                                       16

            (e) If the Borrower fails to pay when due any amount payable under
this Agreement or any other Loan Document, including principal, interest, fees,
reimbursements, and indemnifications, such amount not paid when due shall bear
interest beginning on the date due until paid in full at the Default Rate.

      Section 2.11TAXES.

            (a) Any and all payments by the Borrower to the Lender shall be made
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges, or withholdings, and all liabilities with
respect thereto, excluding taxes imposed on the Lender's income, franchise and
other taxes imposed on the Lender by any jurisdiction of which the Lender is or
is deemed to be a citizen or resident or any political subdivision of such
jurisdiction (all such nonexcluded taxes, levies, imposts, deductions, charges,
withholdings, and liabilities being hereinafter referred to as "Taxes"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable to the Lender, (i) the sum payable shall be increased as may be
necessary so that, after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.11), the Lender
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, and (iii)
the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

            (b) The Borrower agrees to pay and hold the Lender harmless from and
against any and all present and future stamp and other similar taxes with
respect to this Agreement and the Loan Documents and save the Lender harmless
from and against any and all liabilities with respect to or resulting from any
delay or omission to pay such taxes, and indemnify the Lender for the full
amount of such taxes paid by the Lender, whether or not such taxes were
correctly or legally asserted.

      present, or future conditions, events, activities, practices, or incidents
      which may interfere with or prevent the compliance or continued compliance
      of the Borrower and the Subsidiaries with all Environmental Laws except
      for non-compliances which could not be reasonably expected to result in a

The cost to the Borrower and the Subsidiaries of such reprogramming and testing

the Subsidiaries (including reprogramming errors and the failure of others'
systems or equipment) will not result in a Default or Event of Default or
materially adversely affect the business, financial position or results of
operations of the Borrower or the Subsidiaries. Except for such of the
reprogramming referred to in the preceding sentence as may be necessary, the
computer and management information systems of the Borrower and the Subsidiaries

      preceding fiscal year, all in reasonable detail and audited and certified

      the maturity of any such Debt shall have been accelerated, or any such
      Debt shall have been required to be prepaid prior to the stated maturity
      thereof, or any event or condition shall have occurred or exist that
      permits (or, with the giving of notice or lapse of time or both, would
      permit) any holder or holders of such Debt or any Person acting on behalf
      of such holder or holders to accelerate the maturity thereof or require
      any such prepayment.

            (i) This Agreement or any other Loan Document shall cease to be in
      full force and effect or shall be declared null and void or the validity
      or enforceability thereof shall be contested or challenged by any Loan

      events or conditions, if any, have subjected or could in the reasonable
      opinion of the Lender subject the Borrower to any tax, penalty, or other
      liability to a Plan, a Multiemployer Plan, the PBGC, or otherwise (or any
      combination thereof) which in the aggregate exceed or could reasonably be
      expected to exceed One Hundred Thousand and No/100 Dollars ($100,000.00).

      Exchange Act of 1934) of 30% or more of the outstanding shares of voting

      constitute the Board of Directors of the Borrower (the "Incumbent Board")
      cease for any reason to constitute at least a majority of the Board of
      Directors of the Borrower; provided, however, that any

                                       34
<PAGE>
      individual becoming a director of the Borrower subsequent to the Closing
      Date whose election, or nomination for election by the Borrower's's
      shareholders, was approved by a vote of at least a majority of the
      directors then comprising the Incumbent Board, shall be considered as
      though such individual were a member of the Incumbent Board, but
      excluding, for this purpose, any such individual whose initial assumption
      of office occurs as a result of either an actual or threatened election
      contest (as such terms are used in Rule 14a-11 of Regulation 14A
      promulgated under the Securities Exchange Act of 1934) or other actual or
      threatened solicitation of proxies or consents by or on behalf of a Person
      other than the Board of Directors of the Borrower; or the shall cease to
      directly or indirectly own 100% of each class of stock or other equity

            (l) The Borrower or any of the Subsidiaries, or any of their
      properties, revenues, or assets, shall become the subject of an order of
      forfeiture, seizure, or divestiture (whether under RICO or otherwise) and
      the same shall not have been discharged (or provisions shall not be made
      for such discharge) within thirty (30) days from the date of entry
      thereof.

            (m) Any "Event of Default" or similar express occurrence shall exist
      under any Comerica Loan Document.

      Section 8.2 REMEDIES. Upon the occurrence of an Event of Default, and at
any time thereafter during the continuance of such Event of Default the Lender
may exercise one or more of the following remedies:

            (a) If any Event of Default shall have occurred and be continuing,
the Lender, by notice to the Borrower, may terminate its obligation to make the
Loan and declare the aggregate outstanding principal amount of the Loan, all
accrued but unpaid interest thereon, and all other Loan Obligations to be
immediately due and payable, whereupon the same shall immediately become due and
payable;

            (b) If any Event of Default pursuant to Section 8.1(d) or (e) shall
occur, the Lender's obligation to make the Loan shall immediately and
automatically terminate and the aggregate outstanding principal amount of the
Loan, all accrued but unpaid interest thereon, and all other Loan Obligations
shall immediately and automatically become due and payable, all without notice
thereof to the Borrower;

            (c) The Lender may declare by written notice to the Borrower that
the Loan Obligations specified in such notice (including the outstanding
principal amount of the Loan and any past due interest thereon) shall bear
interest beginning on the date specified in such notice, which shall not be
earlier than the date of occurrence of such Event of Default, until paid in full
at the Default Rate, whereupon such Loan Obligations shall accrue interest at
such rate payable to the Lender upon demand;

            (d) The Lender may, to the fullest extent permitted by law, set off
and apply any indebtedness owed by the Lender to the Borrower against any and
all of the obligations of the

                                       35
<PAGE>
Borrower under the Loan Documents, irrespective of whether or not the Lender
shall have made any demand under the Loan Documents and although such
obligations may be unmatured;

            (e) The Lender may take any and all actions permitted under the
other Loan Documents; or

            (f) The Lender may take any and all actions permitted at law or in
equity to enforce the rights of the Lender under the Loan Documents.

In connection with the foregoing, and except for the notices provided for above,
the Borrower waives notice of any Default or Event of Default, notice of
nonpayment, presentment for payment, demand, protest, notice of intent to
accelerate, notice of acceleration, and all other notices.

      Section 8.3 REMEDIES CUMULATIVE. The rights and remedies of the Lender
under the Loan Documents shall be cumulative and shall not exclude any other
rights and remedies of the Lender allowed by law with respect to any default
under the Loan Documents. Failure by the Lender to insist upon the strict
performance of any of the covenants and agreements of the Borrower therein set
forth or to exercise any rights or remedies upon default by the Borrower
thereunder shall not be considered or taken as a waiver or relinquishment for
the future of the right to insist upon and to enforce by appropriate remedy a
strict compliance by the Borrower with all of the covenants and conditions
thereof, or of the rights to exercise any such rights or remedies, if such
default by the Borrower be continued or repeated.

      Section 8.4 NO ADDITIONAL WAIVER IMPLIED BY ONE WAIVER. In the event any
covenant or agreement contained in the Loan Documents should be breached by
either party and thereafter waived by the other party, such waiver shall be
limited to the particular breach so waived and shall not be deemed to waive any
other breach thereunder. No waiver shall be binding unless it is in writing and
signed by the party making such waiver. No course of dealing between the Lender
and the Borrower or any delay or omission on the part of the Lender in
exercising any rights hereunder or under the Loan Documents shall operate as a
waiver.

      Section 8.5 EFFECT ON DISCONTINUANCE OF PROCEEDINGS. In case any
proceeding taken by the Lender under the Loan Documents on account of any Event
of Default shall have been discontinued or abandoned for any reason or shall
have been determined adversely to the Lender, then, and in every such case, to
the fullest extent permitted by law the Borrower and the Lender shall be
restored, respectively, to their former positions and rights thereunder, and all
rights, remedies, powers, and duties of the Lender shall continue as in effect
prior to the commencement of such proceedings.

      Section 8.6 APPLICATION OF PAYMENTS. Prior to an Event of Default, all
payments made on the Loan Obligations shall be applied to the Loan Obligations
as directed by the Borrower, subject to the rules regarding the application of
payments to certain Loan Obligations provided for under this Agreement and the
other Loan Documents. Following the occurrence and during the continuation of an
Event of Default, all payments and collections shall be applied to the Loan
Obligations in the order determined by the Lender.

following circumstances: (i) any lack of validity or enforceability of any
portion of this Agreement or any other Loan Document; (ii) any amendment or
waiver of or any consent to departure from this Agreement or any other Loan
Document; (iii) the existence of any claim, setoff, or defense (other than the
defense that payment has been made to the Lender, or the obligations of the
Borrower to the Lender have otherwise been satisfied or discharged in full);
provided that nothing in this Section 9.1 shall prevent the assertion of any
such claim by separate suit or counterclaim; or (iv) any other circumstance or
happening whatsoever, whether or not similar to any of the foregoing.

      Section 9.2 AMENDMENTS, ETC.

            (a) No amendment, waiver, or other modification of any provision of
any Loan Document, nor consent to any departure by the Borrower therefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Lender and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

            (b) In the event that the Lender assigns, syndicates, or otherwise
transfers any portion of this Agreement and the Loan Documents to any other
Person, the Borrower agrees to amend the Loan Documents or execute successor
documents as reasonably requested by the Lender to reflect the transfer and any
division of rights created thereby and the Lender shall pay the respective costs
and expenses incurred in connection with such assignment or transfer.

      Section 9.3 NOTICES. Unless otherwise specified, all notices and other
communications provided for between the Borrower and the Lender in the Loan
Documents shall be in writing, including telecopy, and delivered or transmitted
to the addresses set forth below, or to such other address as shall be
designated by the Borrower or the Lender in written notice to the other party.
Notice sent by telecopy shall be deemed to be given and received when receipt of

harmless the Lender and its stockholders, directors, officers, employees,
agents, affiliates, successors, and assigns, and their respective stockholders,

                                 PROMISSORY NOTE

$15,000,000.00                   Houston, Texas                    June 30, 1998

      For value received, the undersigned INDUSTRIAL HOLDINGS, INC., a Texas
corporation (the "Borrower"), hereby promises to pay to the order of ENSERCO,
L.L.C. (the "Lender"), the principal amount of FIFTEEN MILLION AND NO/100 UNITED
STATES DOLLARS ($15,000,000.00) or, if less, the aggregate outstanding principal
amount of the Loan (as defined in the Loan Agreement referred to below) made by
the Lender to the Borrower, together with accrued but unpaid interest on the
outstanding principal amount of the Loan, at such interest rates, and at such
times, as are specified in the Loan Agreement.

      This Promissory Note (this "Note") is entitled to the benefits of, and is
subject to the terms of, the Loan Agreement dated as of June 30, 1998 (as the
same may be modified from time to time, the "Loan Agreement"), between the
Borrower and the Lender. Capitalized terms used herein but not defined herein
shall have the meanings specified by the Loan Agreement. The Loan Agreement,
among other things, (a) provides for the making of the Loan by the Lender to the
Borrower, the indebtedness of the Borrower resulting from each such advance
being evidenced by this Note and (b) contains provisions for acceleration of the
maturity of this Note upon the happening of certain events stated in the Loan
Agreement and for prepayments of principal prior to the maturity of this Note
upon the terms and conditions specified in the Loan Agreement. Both principal
and interest are payable to the Lender in the currency, at the times, in the
locations, and in the manner specified in the Loan Agreement.

      It is the intention of the Lender and the Borrower to conform strictly to
any applicable usury laws or relevant exemptions therefrom. Accordingly, the
terms of the Loan Agreement relating to the prevention of usury will be strictly
followed.

      This Note shall be governed by, and construed in accordance with, the
internal laws of the State of Texas (without reference to principles of
conflicts of law).

      THIS NOTE AND THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.
