                         SUPPLEMENTAL BENEFIT AGREEMENT

         This Supplemental Benefit Agreement (this "Agreement"), dated December
13, 2002, is by and between NCI Building Systems, Inc. (the "Company"), and
Johnie Schulte ("Employee").

                                     PURPOSE

         The purpose of this Agreement is to provide retirement and survivor
benefits to or on behalf of a member of senior management or highly compensated
Employee on the terms and conditions set forth herein to reward Employee for
loyal service to the Company and to provide an incentive to remain in the employ
of the Company. The Company intends that this Agreement shall constitute an
unfunded deferred compensation arrangement for a member of a select group of
senior management or highly compensated employee for purposes of the Internal
Revenue Code of 1986, as amended (the "Code") and of the Employee Retirement
Income Security Act of 1974, as amended, and that Employee or Beneficiary shall
have the status of an unsecured general creditor of the Company in the event the
Company becomes Insolvent as to this Agreement and any trust fund that may be
established by the Company, or asset identified specifically by the Company, as
a reserve for the discharge of its obligations under this Agreement. Benefits
provided under this Agreement are in addition to any other benefit plans or
programs of the Company. The existence of this Agreement does not limit or
otherwise affect Employee's participation in any other plan sponsored by the
Company.

         3.2 Retirement Benefits. Except as provided in Section 3.5, the
Retirement Benefit credited to Employee's bookkeeping account pursuant to
Section 3.1, to the extent vested under Section 3.4, shall become payable in the
form described herein to Employee. Employee's Retirement Benefit shall be paid
in equal annual installments over a period of seven (7) years commencing on the
fourth anniversary of the earlier of Employee's Normal Retirement Date or the
date Employee ceases active employment with the Company due to his Disability;
provided that on each annual payment date Employee has not breached or violated
any of his or her covenants set forth in Article V hereof. If Employee dies
prior to receiving the entire Retirement Benefit to which he or she is entitled
and has not breached or violated any of his or her covenants set forth in
Article V hereof, Employee's Beneficiary shall receive the unpaid portion of
Employee's Retirement Benefit in equal annual payments during the remainder of
the 7-year period. Notwithstanding any other provision of this Agreement to the
contrary, if Employee breaches or violates any of his or her covenants set forth
in Article V hereof, Employee immediately shall forfeit his or her rights to any
remaining Retirement Benefit under this Agreement.

         3.3 Preretirement Survivor Benefit. If Employee dies while employed by
the Company, Employee shall not be entitled to a Retirement Benefit and
Employee's Beneficiary shall receive the Preretirement Survivor Benefit credited
to Employee's bookkeeping account under Section 3.1 payable in equal annual
installments over a period of 7 years. Payment of the Beneficiary's
Preretirement Survivor Benefit shall commence on the fourth anniversary of the
date of death of Employee. If Employee's Beneficiary dies prior to the payment
of the entire Preretirement Survivor Benefit, the then present value of
Beneficiary's remaining Preretirement Survivor Benefit, determined in accordance
with Section 3.5(c) hereof, shall be paid to Beneficiary's estate in a single
sum distribution within 30 days after the date of Beneficiary's death.

         3.4 Vesting.

                  (a) If, at the time of execution of this Agreement, Employee
has ten or more years until he reaches Normal Retirement Age, Employee's right
to a Retirement Benefit shall vest over a period of 10 years, at the rate of 10%
for each Year of Participation by Employee. If, at the time of execution of this
Agreement, Employee has three or fewer years until he reaches Normal Retirement
Age, Employee's right to a Retirement Benefit shall vest over a period of three
(3) years, at the rate of 33-1/3% for each Year of Participation by Employee. In
addition, Employee shall become fully vested in his or her Retirement Benefit
upon the occurrence of his or her death, Disability or a Change in Control.
Notwithstanding any other provision of this Agreement to the contrary, if
Employee's employment with the Company is terminated for Cause, Employee shall
forfeit his or her rights to any benefits under this Agreement.

                  (b) Employee acknowledges and agrees that during the vesting
period described in Section 3.4(a) above, the Company may, from time to time, be
required by applicable law to withhold amounts for certain federal employment
taxes related to or incurred in connection with the amount of the benefit vested
during each Year of Participation (the "Employment Taxes"). Employee may elect,
in his sole discretion, to pay such Employment Taxes by either (i) delivering to
the Company a check, cash or other readily available funds in an amount equal to
the Employment Taxes no later than 30 days prior to the end of the applicable
Year of Participation, or

SUPPLEMENTAL BENEFIT AGREEMENT - JOHNIE  SCHULTE                          Page 4
<PAGE>

(ii) executing such documentation as the Company may require authorizing the
Company to, beginning July 1 of the applicable Year of Participation, withhold
from the Employee's compensation, in substantially equal amounts per pay period,
the Employment Taxes. Notwithstanding the foregoing, if Employee terminates
service with the Company subsequent to receiving a Year of Participation for
vesting purposes under the Plan but prior to paying the entire amount of
Employment Taxes applicable to such Year of Participation, Employee agrees, in
the sole discretion of the Company, to either (i) execute such documentation as
the Company may require authorizing the Company to withhold from the Employee's
final paycheck the balance of the Employment Taxes due or (ii) deliver to the
Company a check, cash or other readily available funds in an amount equal to the
Employment Taxes no later than the date of termination of Employee's employment
with the Company.

         3.5 Timing of Certain Payments. Notwithstanding the provisions of
Section 3.2, benefits will be paid to Employee or if applicable his or her
Beneficiary upon the following terms:

                  (a) If Employee's employment with the Company is terminated
without Cause on or after the occurrence of a Change in Control (irrespective of
whether such termination is initiated by Employee or the Company and without
regard to the reason therefor), the present value of Employee's Retirement
Benefit, determined in accordance with Section 3.5(c) hereof, shall be paid to
Employee in a single sum distribution within 30 days after Employee's
termination of employment.

                  (b) If Employee's employment with the Company is terminated
without Cause prior to the occurrence of a Change in Control (irrespective of
whether such termination is initiated by Employee or the Company and without
regard to the reason therefor), Employee shall become fully vested in his or her
Retirement Benefit, which Retirement Benefit shall be paid as provided in
Section 3.2. If a Change in Control occurs while Employee is entitled to receive
his Retirement Benefit, the then present value of Employee's remaining
Retirement Benefit, determined in accordance with Section 3.5(c) hereof, shall
be paid to Employee in a single sum distribution within 30 days after such
Change in Control.

                  (c) For purposes of this Agreement, whenever the Company is
required to calculate the present value of any benefit to be paid to Employee or
Beneficiary hereunder, the Company shall calculate the present value of such
benefit using a discount rate equal to the prime rate reported by the Company's
principal bank lender on the date on which such payment became payable (i.e.,
the date of termination of Employee's employment with the Company or the
occurrence of a Change in Control), but in no event shall such discount rate
exceed 8%.

                  (d) The Administrator may make payments from this Agreement
before they would otherwise be due if, based on a change in the federal or
applicable state tax or revenue laws, a published ruling or similar announcement
issued by the Internal Revenue Service, a regulation issued by the Secretary of
the Treasury, a decision by a court or competent jurisdiction involving Employee
or a Beneficiary, or a closing agreement made under Code section 7121 that is
approved by the Internal Revenue Service and involves Employee, the
Administrator determines that Employee has or will recognize income for federal
or state income tax purposes with respect to amounts that are or will be payable
under this Agreement before they otherwise would be paid.

<PAGE>

The amount of any payments made from this Agreement pursuant to this Section 3.5
shall not exceed the lesser of (i) the amount in the trust properly allocable to
Employee or (ii) the amount of taxable income with respect to which the tax
liability is assessed or determined.

         3.6 Financing this Agreement. All benefits under this Agreement shall
be paid or provided directly by the Company. Such benefits shall be general
obligations of the Company which shall not require the segregation of any funds
or property therefor. Notwithstanding the foregoing, in the discretion of the
Company, the Company's obligations hereunder may be satisfied from a grantor
trust established by the Company or from an insurance contract, annuity or
similar funding vehicle owned by the Company. The assets of any such trust,
insurance contract, or other funding vehicle shall continue for all purposes to
be a part of the general funds of the Company, shall be considered solely a
means to assist the Company to meet its contractual obligations under this
Agreement and shall not create a funded account or security interest for the
benefit of Employee under this Agreement. All such assets shall be subject to
the claims of the general creditors of the Company in the event the Company is
Insolvent. To the extent that any person acquires a right to receive a payment
from the Company under this Agreement, such right shall be no greater than the
right of any unsecured general creditor of the Company.

         3.7 Death of Employee. In the event of Employee's death, the Company
shall make any payments called for hereunder to his or her Beneficiary in the
manner described in Section 3.2 or 3.3, as applicable, following his or her
death. Any payment made by the Company in good faith shall fully discharge the
Company from its obligations with respect to such payment, and the Company shall
have no further obligation to see to the application of any money so paid.

         3.8 Claims Procedure. Employee or Beneficiary may make a claim for
specific benefits under this Agreement by filing a written request with the
Company. If a claim is wholly or partially denied, notice of the decision shall
be furnished to the claimant within 60 days after receipt of the claim by the
Company, unless special circumstances require an extension of time for
processing the claim, in which case a decision shall be rendered as soon as
possible, but in no event later than 120 days after receipt of the claim.
Written notice of the extension shall be furnished to the claimant prior to the
termination of the initial 60-day period, and shall indicate the circumstances
requiring the extension and the date by which the Company expects to render its
decision. The notice of the decision shall contain the specific reason or
reasons for the denial of the claim, specific references to pertinent provisions
of this Agreement on which the denial is based, a description of any additional
material or information necessary for the claimant to perfect the claim, an
explanation of why such additional material or information is necessary and an
explanation of the claims review procedure in this Agreement. If notice of the
denial is not furnished in accordance with the above procedure, the claim shall
be deemed denied and the claimant shall be permitted to proceed with the review
procedure. A claimant or his duly authorized representative may appeal the
denial of a claim by making a written application to the Company requesting a
review. The claimant or his duly authorized representative may, in connection
with the appeal, review pertinent documents and submit issues and comments to
the Company in writing. The request for a review of a denied claim must be made
to the Company within 60 days after receipt by the claimant of written
notification of denial of a claim. A decision by the Company shall be made no
later than 60 days after its receipt of a request for a review, unless special
circumstances require an extension of time for processing the request, in which
case

SUPPLEMENTAL BENEFIT AGREEMENT - JOHNIE  SCHULTE                          Page 6
<PAGE>

a decision shall be rendered as soon as possible, but in no event later than 120
days after receipt of the request for review. If such an extension of time for
review is required, written notice of the extension shall be furnished to the
claimant prior to the commencement of the extension. The decision on review
shall be in writing and shall include specific reasons for the decision and
specific references to the pertinent Agreement provisions on which the decision
is based. If the decision on review is not furnished within the appropriate
time, the claim shall be deemed denied on review. All interpretations,
determinations, and decisions by the Company in respect of any matter hereunder
will be final, conclusive, and binding upon the Company, Employee,
Beneficiaries, and all other persons claiming any interest in this Agreement.

         3.9 Arbitration. If Employee or Beneficiary has completed the claims
procedures set forth in Section 3.8 and decides to pursue his or her claim
further, Employee or Beneficiary shall comply with the following procedures:

                  (a) The exclusive remedy or method of resolving all disputes
or questions arising out of or relating to this Agreement shall be arbitration.
Arbitration shall be held in Houston, Texas by three arbitrators, one to be
appointed by the Company, a second to be appointed by Employee (or Beneficiary,
if applicable), and a third to be appointed by those two arbitrators. The third
arbitrator shall act as chairman. Any arbitration may be initiated by Employee
(or Beneficiary) by written notice to the Company specifying the subject of the
requested arbitration and appointing Employee's (or Beneficiary's) arbitrator
("Arbitration Notice").

                  (b) If (i) the Company fails to appoint an arbitrator by
written notice to Employee (or Beneficiary) within ten days after the
Arbitration Notice is given, or (ii) the two arbitrators appointed by the
parties herein fail to appoint a third arbitrator within ten days after the date
of the appointment of the second arbitrator, then the American Arbitration
Association in Houston, Texas, upon application of Employee (or Beneficiary)
shall appoint an arbitrator to fill that position.

                  (c) The arbitration proceeding shall be conducted in
accordance with the rules of the American Arbitration Association. A
determination or award made or approved by at least two of the arbitrators shall
be the valid and binding action of the arbitrators. The costs of arbitration
(exclusive of the expense of a party in obtaining and presenting evidence and
attending the arbitration and of the fees and expense of legal counsel to a
party, all of which shall be borne by that party) shall be borne by the Company
if Employee (or Beneficiary) receives substantially the relief sought by
Employee (or Beneficiary) in the arbitration, whether by settlement, award, or
judgment; otherwise, the costs shall be borne equally by the parties. The
arbitration determination or award shall be final and conclusive on the parties,
and judgment upon such award may be entered and enforced in any court of
competent jurisdiction.

                                   ARTICLE IV

hereof, and actions hereunder, including any determination of the amount or
recipient of any payment to be made under this Agreement, shall be binding and
conclusive on all persons and for all purposes. The Board may request that
certain employees assist the Administrator in its administration of this
Agreement. The Administrator may employ attorneys, accountants, actuaries and
other professional advisors to assist the Administrator in its administration of

Board or any employee or officer of the Company shall be liable to any person
for any action taken or omitted in connection with the interpretation and
administration of this Agreement unless attributable to his or her own willful
misconduct or lack of good faith.

         4.2 Indemnification of Employees of the Company. The Company hereby
agrees to indemnify, jointly and severally, all members of the Board and all
employees of the Company against any and all claims, losses, damages, expenses,
including counsel fees, incurred by them, and any liability, including any
amounts paid in settlement with their approval arising from their action or
failure to act with respect to any matter relating to this Agreement, except
when the same is judicially determined to be attributable to their willful
misconduct or lack of good faith. The indemnification provided by this Section
4.2 shall survive the termination of this Agreement and shall be binding upon
the Company's successors and assigns.

         4.3 Cost of Administration. The cost of this Agreement and the expenses
of administering this Agreement shall be paid by the Company.

                                    ARTICLE V
                      NON-COMPETITION AND NON-SOLICITATION

         In consideration for participation in this Agreement, Employee hereby
covenants and agrees as follows:

                  (a) At all times during the period in which he receives
Retirement Benefits pursuant to Section 3.2 hereof, Employee shall not, directly
or indirectly and whether on his own behalf or on behalf of any other person,
partnership, association, corporation or other entity, engage in or be an owner,
director, officer, employee, agent, consultant or other representative of or for
any business that manufactures, engineers, markets, sells or provides, in any
state of the United States of America, metal building systems or components
(including, without limitation, primary and secondary framing systems, roofing
systems, end or side wall panels, doors, windows or other metal components of a
building structure), coated or painted steel or metal coils, coil coating or
painting services, or any other products or services that are the same as or
similar to those manufactured, engineered, marketed, sold or provided by the
Company or its subsidiaries and affiliates during the period of employment of
Employee by the Company. Ownership by Employee of equity securities of the
Company, or of equity securities in other publicly owned companies constituting
less than 1% of the voting securities in such companies, shall be deemed not to
be a breach of this covenant.

                  (b) At all times during the period in which he receives
Retirement Benefits pursuant to Section 3.2 hereof, Employee shall not, directly
or indirectly and whether on his own

<PAGE>

behalf or on behalf of any other person, partnership, association, corporation
or other entity, either hire, seek to hire or solicit the employment of any
employee of the Company or in any manner attempt to influence or induce any
employee of the Company or its subsidiaries and affiliates to leave the
employment of the Company or its subsidiaries and affiliates, or use or disclose
to any person, partnership, association, corporation or other entity any
information concerning the names and addresses of any employees of the Company
or its subsidiaries and affiliates unless required by due process of law.

                                   ARTICLE VI
                            AMENDMENT AND TERMINATION

         6.1 Amendment. The Company, by action of the Board, shall have the
right to amend this Agreement at any time and from time to time, including a
retroactive amendment, by resolution adopted by the Board. Any such amendment
shall become effective upon the date stated therein, except as otherwise
provided in such amendment; provided, however, that no such action shall affect
any benefit adversely to which Employee would be entitled had his employment
terminated immediately before such amendment was effective.

         6.2 Termination. The Company has entered into this Agreement with the
bona fide intention and expectation that from year to year it will deem it
advisable to continue it in effect. However, the Board, in its sole discretion,
reserves the right to terminate this Agreement in its entirety at any time;
provided, however, that (i) Employee's benefits hereunder shall not be affected
by the termination where the event giving rise to the benefit (Employee's
termination of employment, death or disability, or a Change in Control) has
occurred and (ii) no such action shall affect any benefit adversely to which
Employee would be entitled had his employment terminated immediately before such
termination was effective.

                                   ARTICLE VII
                               GENERAL PROVISIONS

         7.1 Rights Against the Company. This Agreement shall not be deemed to
constitute an employment contract between the Company and Employee or to be a
consideration for, or an inducement for, the employment of Employees by the
Company. Nothing contained in this Agreement shall be deemed to give Employee
the right to be retained in the service of the Company or to interfere with the
right of the Company to discharge Employee at any time, without regard to the
effect such discharge may have on any rights under this Agreement.

         7.2 Payment Due an Incompetent. If the Company shall find that any
person to whom any payment is payable under this Agreement is unable to care for
his affairs because of mental or physical illness, accident, or death, or is a
minor, any payment due (unless a prior claim therefor shall have been made by a
duly appointed guardian, committee or other legal representative) may be paid to
the spouse, a child, a parent, a brother or sister or any person deemed by the
Company, in its sole discretion, to have incurred expenses for such person
otherwise entitled to payment, in such manner and proportions as the Company may

                      SPLIT-DOLLAR LIFE INSURANCE AGREEMENT

         This Agreement is entered into as of the February 1, 1996, by and
between NCI Building Systems, Inc., a Delaware corporation (hereinafter referred
to as the "Corporation") and Fred D. Koetting (the "Employee").

                                    RECITALS:

         WHEREAS, the Employee is a key employee of the Corporation and the
Corporation desires to encourage the Employee to remain an employee of the
Corporation; and

         WHEREAS, to encourage the Employee to remain an employee of the
Corporation, the Corporation desires to assist the Employee in establishing a
life insurance program; and

         WHEREAS, the Employee has insured his life under a life insurance
policy described herein; and

         WHEREAS, the Corporation and the Employee desire to enter into a
contractual arrangement to establish their respective rights with respect to
such policy;

         NOW THEREFORE, in consideration of the mutual covenants contained
herein, the parties hereto agree as follows:

         1. Designation of Policy. The life insurance policy which is the
subject of this Agreement is Policy No. 13-716-906 (the "Policy") issued by The
Northwestern Mutual Life Insurance Company (the "Insurer") on the life of the
Employee.

         2. Ownership of Insurance. The Employee shall be the sole owner of the
Policy and the Employee may exercise all the rights of ownership with respect to
the Policy, except as otherwise hereinafter provided.

         3. Dividends. All dividends declared or distributions made by the
Insurer on the Policy shall be applied to purchase additional paid-up insurance
on the life of the Employee.

         4. Premium Payments. On or before the due date, the Corporation will
pay to the Insurer the full amount of each premium on the Policy. The aggregate
amount of premiums paid by the Corporation on the Policy on or after April 1,
1996 shall, as of any determination date, be referred to as the "Corporation
Premiums".

         5. Tax Reporting By Employee. During the term of this Agreement, the
Employee shall report as compensation each year an amount equal to the one-year
term cost of the Policy, including insurance purchased by dividends, as such
cost is determined pursuant to Revenue Rulings 64-328 and 66-110 issued by the
Internal Revenue Service,which shall be the lesser of the P.S. 58 cost under the
tables contained in Revenue Ruling 55-747 or the Insurer's individual initial
issue one-year term life insurance rates. If during the term of this Agreement,
the method

SPLIT-DOLLAR LIFE INSURANCE AGREEMENT                                     Page 1
FRED D. KOETTING
<PAGE>

for determining the Employee's annual compensation associated with the Policy is
different than the method described in the preceding sentence due to changes in
the tax laws applicable to this Agreement or the issuance of rulings or
regulations by the Internal Revenue Service, the Employee shall report as
compensation an amount consistent with the requirements of such laws, rulings or
regulations.

         6. Employee's Obligation to Corporation. The Employee shall be
obligated to repay to the Corporation the Corporation Premiums. The Employee's
repayment obligation to the Corporation described in this Section 6 shall be
payable as prescribed in Sections 10 and 13 of this Agreement.

         7. Collateral Assignment of Policy. As security for the repayment to
the Corporation of the Corporation Premiums paid pursuant to Section 4 of this
Agreement, the Employee has executed an assignment of the Policy (the
"Assignment"), which Assignment is attached hereto as Exhibit A. During the term
of this Agreement, the Employee's rights of ownership with respect to the Policy
shall be limited to those specified in the Assignment. Except as provided in
this Agreement, the Assignment will not be altered without the written consent
of the Corporation.

         8. Right to Obtain Policy Loans. The Corporation shall have the right
to obtain Policy loans or advances on the Policy equal to the amount of the
Corporation Premiums paid to the date of the loan or advance.

         9. Assignment of Employee's Interest. Except as provided otherwise in
this Section 9, the Employee may not transfer or assign his rights in the Policy
(other than the rights assigned to the Corporation pursuant to this Agreement
and the Assignment). Notwithstanding the preceding sentence, with the consent of
the Corporation, Employee may assign his rights in the Policy (other than rights
assigned to the Corporation pursuant to this Agreement and the Assignment) to a
life insurance trust established by Employee.

         10. Death of Employee. Upon the death of the Employee, the Corporation
shall be entitled to receive, from the proceeds of the Policy, an amount equal
to the Corporation Premiums paid pursuant to Section 4 of this Agreement, less
any Policy loans or other indebtedness incurred by the Corporation and secured
by the cash surrender value of the Policy. The balance, if any, of the proceeds
of the Policy will be paid directly by the Insurer to the beneficiary designated
in the Policy by the Employee. If, pursuant to the terms of the Assignment, the
Insurer pays the Corporation amounts in excess of the Corporation Premiums in
connection with the death of the Employee, the Corporation shall pay such excess
amounts to the beneficiary designated in the Policy by the Employee, as
determined and communicated to the Corporation by the Insurer.

         11. Designation of Beneficiaries Under Policy. The Employee shall have
the right to designate and change direct and contingent beneficiaries to receive
the balance of any Policy proceeds payable on account of the Employee's death
following payment of Corporation Premiums to the Corporation pursuant to Section
4 of this Agreement and to elect a payment

FRED D. KOETTING
<PAGE>

plan for such beneficiaries, subject to the Assignment and the rights of the
Corporation thereunder.

         12. Termination of Agreement. Subject to the provisions of Section 13,
this Agreement shall terminate on the occurrence of any of the following events:

                  (a) After payment of the amounts specified in Section 10
following the death of the Employee;

                  (b) Cessation of the Corporation's business;

                  (c) Termination of the Employee's employment with the
Corporation; or

                  (d) Upon the election of the Corporation, provided that the
Corporation gives written notice of the Corporation's election to terminate this
Agreement pursuant to this paragraph (d) at least ninety (90) days prior to the
effective date of such termination.

         13. Disposition of Policy on Termination of Agreement. If this
Agreement is terminated under Section 12, the Corporation will no longer be
obligated to pay the premium on the Policy pursuant to Section 4. The following
provisions shall apply in the event of a termination of the Agreement pursuant
to Section 12:

                  (a) Termination of Agreement on Account of Cessation of
Business of Corporation, Employee's Voluntary Termination of Employment, or at
the Election of the Corporation. If this Agreement is terminated on account of
(i) the cessation of the Corporation's business under paragraph (b) of Section
12; (ii) the Employee's voluntary termination of employment under paragraph (c)
of Section 12; or (iii) termination of the Agreement by the Corporation pursuant
to paragraph (d), the Employee shall have the right for a period of sixty (60)
days following the termination event to repay the Corporation the Corporation
Premiums. The Employee may elect to repay such premiums by surrendering the
Policy and reimbursing the Corporation for such costs from the cash surrender
value of the Policy. Alternatively, the Employee may elect to reimburse the
Corporation for the Corporation Premiums paid as of the termination date without
surrendering the Policy. Upon receipt of this amount, the Corporation shall
release the Assignment of the Policy, and the Employee shall become the sole and
absolute owner of the Policy. The Employee may thereafter elect to continue to
keep the Policy in effect by paying the premiums thereon, or alternatively, may
elect to surrender the Policy pursuant to the terms thereof. If the Employee
fails to repay the Corporation the amount of the Corporation Premiums within
this sixty (60) day period, the Employee shall execute any and all documents
necessary to vest ownership of the Policy in the Corporation. Thereafter,
Employee shall have no interest in the Policy.

                  (b) Termination of Agreement on Account of the Involuntary
Termination of Employee's Employment. If this Agreement is terminated on account
of the involuntary termination of Employee's employment by the Corporation for
reasons other than for "Cause" (as hereinafter defined) under paragraph (c) of
Section 12, the Corporation shall waive its right to

SPLIT-DOLLAR LIFE INSURANCE AGREEMENT                                     Page 3
FRED D. KOETTING
<PAGE>

repayment of the Corporation Premiums. Within sixty (60) days of such
involuntary termination of employment, the Corporation shall release the
Assignment of the Policy and pay the amount of any Policy loans or other
indebtedness incurred by the Corporation on the Policy, and the Employee shall
become the sole and absolute owner of the Policy with all rights of ownership
therein. The Employee may thereafter elect to continue to keep the Policy in
effect by paying the premiums thereon, or alternatively, may elect to surrender
the Policy pursuant to the terms thereof. If the Employee's employment is
terminated by the Corporation for Cause, the Employee shall have no interest in
the Policy and shall not be entitled to any benefits thereunder or any portion
of the Policy's cash surrender value. In such event, the Corporation may take
any action it deems appropriate with respect to the disposition of the Policy.
As used in this Agreement, "Cause" shall be determined by the Board, in its sole
and absolute discretion, and means the occurrence of either or both of the
following:

                           (i) The Employee's conviction for committing an act
                  of fraud, embezzlement, theft, or other act constituting a
                  felony; or

                           (ii) The willful engaging by the Employee in gross
                  misconduct materially and demonstrably injurious to the
                  Corporation, as determined by the Corporation. However, no act
                  or failure to act, on the Employee's part shall be considered
                  "willful" unless done, or omitted to be done, by the Employee
                  not in good faith and without reasonable belief that his
                  action or omission was in the best interest of the
                  Corporation.

         14. Insolvency of Corporation. In the event the Corporation becomes
insolvent during the term of the Agreement, the cash surrender value of the
Policy shall be subject to the claims of the Corporation's creditors and the
Employee shall have the status of an unsecured creditor of the Corporation with
respect to the portion of cash surrender value of the Policy, if any, otherwise
payable to Employee under this Agreement. For purposes of the preceding
sentence, the Corporation shall be considered as "insolvent" if (i) the
Corporation is unable to pay its debts as they become due or (ii) the
Corporation is subject to a pending proceeding as a debtor under the United
States Bankruptcy Code.

         15. Paid-Up Additional Life Insurance. Any payments under the Policy to
the Corporation in connection with the rights granted to the Corporation in the
Assignment shall first be made from the cash surrender value under the Policy
attributable to the paid-up additional life insurance purchased by Policy
dividends. The Employee shall have no interest in the paid-up additional life
insurance protection to the extent the death benefit or cash value thereof
exceeds the total amount which must be paid to the Corporation under this
Agreement.

         16. Named Fiduciary. The Board of Directors of the Corporation (the
"Board") is designated as the "Named Fiduciary," as defined under section 402 of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), of
the split-dollar life insurance arrangement set forth in this Agreement. The
business address and telephone number of the Named Fiduciary are:

                           (713) 466-7788

The Named Fiduciary shall have full power and authority to control and manage
the operation and administration of this Agreement and to interpret and construe
the terms hereof. The Named Fiduciary's interpretation and construction hereof
and actions hereunder shall be binding and conclusive on all persons for all
purposes. However, the Named Fiduciary may allocate its responsibilities for the
operation and administration of this Agreement, including the designation of
persons who are not named fiduciaries, to carry out all or a portion of its
responsibilities under the Agreement. The Named Fiduciary shall be responsible
for making timely delivery of any required premiums under the Policy to the
Insurer during the term of this Agreement. A copy of the Assignment and the
Policy has been provided to Employee upon the execution of this Agreement.

         17. Claims Procedure. Any person claiming a benefit under the Agreement
(a "Claimant") shall present the claim in writing to the Board and the Board
shall respond thereto in writing in accordance with this Section 17. If a claim
is wholly or partially denied, notice of the decision shall be furnished to the
Claimant within 60 days after receipt of the claim by the Board, unless special
circumstances require an extension of time for processing the claim, in which
case a decision shall be rendered as soon as possible, but in no event later
than 120 days after receipt of the claim. Written notice of the extension shall
be furnished to the Claimant prior to the termination of the initial 60-day
period, and shall indicate the circumstances requiring the extension and the
date by which the Board expects to render its decision. The notice of the
decision shall contain the specific reason or reasons for the denial of the
claim, specific references to pertinent provisions of the Agreement on which the
denial is based, a description of any additional material or information
necessary for the Claimant to perfect the claim, an explanation of why such
additional material or information is necessary and an explanation of the
Agreement's claims review procedure. If notice of the denial is not furnished in
accordance with the above procedure, the claim shall be deemed denied and the
Claimant shall be permitted to proceed with the review procedure. A Claimant or
his duly authorized representative may appeal the denial of a claim by making a
written application to the Board requesting a review. The Claimant or his duly
authorized representative may, in connection with the appeal, review pertinent
documents and submit issues and comments to the Board in writing. The request
for a review of a denied claim must be made to the Board within 60 days after
receipt by the Claimant of written notification of denial of a claim. A decision
by the Board shall be made no later than 60 days after its receipt of a request
for a review, unless special circumstances require an extension of time for
processing the request, in which case a decision shall be rendered as soon as
possible, but in no event later than 120 days after receipt of the request for
review. If such an extension of time for review is required, written notice of
the extension shall be furnished to the Claimant prior to the commencement of
the extension. The decision on review shall be in writing and shall include
specific reasons for the decision and specific references to the pertinent

SPLIT-DOLLAR LIFE INSURANCE AGREEMENT                                     Page 5
FRED D. KOETTING
<PAGE>

provisions of the Agreement on which the decision is based. If the decision on
review is not furnished within the appropriate time, the claim shall be deemed
denied on review. All interpretations, determinations, and decisions by the
Board in respect of any matter hereunder will be final, conclusive, and binding
upon the Board, Employees, beneficiaries, and all other persons claiming any
interest under the Agreement.

         18. Arbitration. If an Employee or his beneficiary has completed the
claims procedures set forth in Section 17 and decides to pursue his claim
further, the Employee or beneficiary shall comply with the following procedures:

                  (a) The exclusive remedy or method of resolving all disputes
or questions arising out of or relating to this Agreement shall be arbitration.
Arbitration shall be held in Houston, Texas by three arbitrators, one to be
appointed by the Board, a second to be appointed by the Employee (or
beneficiary, if applicable), and a third to be appointed by those two
arbitrators. The third arbitrator shall act as chairman. Any arbitration may be
initiated by the Employee (or beneficiary) by written notice to the Board
specifying the subject of the requested arbitration and appointing the
Employee's (or beneficiary's) arbitrator ("Arbitration Notice").

                  (b) If (i) the Board fails to appoint an arbitrator by written
notice to the Employee (or beneficiary) within ten days after the Arbitration
Notice is given, or (ii) the two arbitrators appointed by the parties herein
fail to appoint a third arbitrator within ten days after the date of the
appointment of the second arbitrator, then the American Arbitration Association
in Houston, Texas, upon application of the Employee (or beneficiary) shall
appoint an arbitrator to fill that position.

                  (c) The arbitration proceeding shall be conducted in
accordance with the rules of the American Arbitration Association. A
determination or award made or approved by at least two of the arbitrators shall
be the valid and binding action of the arbitrators. The costs of arbitration
(exclusive of the expense of a party in obtaining and presenting evidence and
attending the arbitration and of the fees and expense of legal counsel to a
party, all of which shall be borne by that party) shall be borne by the Board if
the Employee (or beneficiary) receives substantially the relief sought by the
Employee (or beneficiary) in the arbitration, whether by settlement, award, or
judgment; otherwise, the costs shall be borne equally by the parties. The
arbitration determination or award shall be final and conclusive on the parties,
and judgment upon such award may be entered and enforced in any court of
competent jurisdiction.

         19. Amendment of Agreement. This Agreement shall not be amended except
by mutual written agreement between the Employee and the Corporation which shall
be signed by the Employee on behalf of the Employee and by the Corporation.

         20. Successors and Assigns. This Agreement shall bind and inure to the
benefit of the Corporation and its successors and assigns and the Employee and
the Employee's successors and assigns.
