                           NCI BUILDING SYSTEMS, INC.

                                  BONUS PROGRAM

      [AMENDED AND RESTATED AS OF DECEMBER 11, 1998 AND SEPTEMBER 9, 1999]

         In 1989, the Board of Directors of NCI Building Systems, Inc. (then
named National Components Incorporated), a Delaware corporation (the "Company"),
adopted the Bonus Program (the "Program"). The Company subsequently amended the
Program from time to time.

         On December 11, 1998, the Board of Directors of the Company amended and
restated the Program in its entirety to, among other things, provide for a new
bonus performance standard for persons eligible to participate in the Program
and set forth certain adjustments to return on assets and earnings per share
growth figures in calculating bonus levels under the Program, and on September
9, 1999, the Compensation Committee of the Board of Directors adopted a
corrective amendment and restatement of the Program.

         The Program, as so amended and restated, is as follows:

         1.       Purpose.  The purpose of the Bonus Program (the "Program") is:

                  (A) To provide exceptional cash rewards earned by exceptional
performance such that the aggregate bonuses paid to all of the Company's
employees in a fiscal year, including those awarded under the Program,
approximate 10% of the pre-tax, pre-bonus profits of the Company for that fiscal
year; and

                  (B) To focus management attention on key objectives of the
Company by basing their bonus on return on assets and growth in earnings per
share.

         2.       Administration. The Program will be administered and
interpreted by the Compensation Committee of the Board of Directors of the
Company (the "Committee").

         3.       Bonus Performance Standards.

                  (A) Combination of ROA and EPS. Level 1 and Level 2
participants will be eligible for the award of an annual cash bonus equal to a
percentage of their respective base salaries, based upon the Company's
achievement of both a specified return on assets ("ROA") and a specified
increase in earnings per share ("EPS Growth") for the fiscal year.

                      No cash bonuses will be awarded to these participants if
(1) both ROA and EPS Growth are less than 20%, or (2) ROA is less than 10%.

                      Subject to the minimum requirements for ROA and EPS
Growth, Level 2 participants will be eligible for a cash bonus award based upon
the attached grid of ROA and EPS Growth achievement, in which the bonus eligible
for award is the percentage of base salary indicated at each intersecting grid
mark for ROA and EPS Growth (e.g., ROA of 30% and EPS Growth of 20% results in a
50% cash bonus). The maximum bonus for Level 2 participants will be 85% of base
salary.

                      Cash bonus awards for which Level 1 participants are
eligible also will be based on the attached grid of ROA and EPS Growth
achievement, but will be 1.5 times the percentage of base salary indicated for
the Level 2 participants. The maximum bonus for Level 1 participants will be
127.5% of base salary.

                  (B) ROA Only. Level 3 and Level 4 participants will be
eligible for the award of a cash bonus equal to a percentage of their respective
base salaries, based upon the Company's achievement of a specified ROA for the
fiscal year.

                      No cash bonuses will be awarded to these participants if
ROA is less than 20%.

                      If ROA is 20% or more, Level 3 participants will be
eligible for the award of a cash bonus equal to 25% of base salary and an
additional 2.50% of base salary for each 1% increment in ROA over 20%. The
maximum bonus for Level 3 participants will be 50% of base salary.

                      If ROA is 20% or more, Level 4 participants will be
eligible for the award of a cash bonus equal to 12.5% of base salary and an
additional 1.25% of base salary for each 1% increment in ROA over 20%. The
maximum bonus for Level 4 participants will be 25% of base salary.

         4.       Participants and Eligibility.

                  (A) Whether or not to award a cash bonus to any particular
participant is within the absolute discretion of the Company and the Committee.
No bonus award to a Level 1, 2 or 3 participant may be paid unless and until and
approved by the Committee, and no bonus award may be paid to a Level 4
participant unless and until the Committee has approved the aggregate employee
bonus pool for that fiscal year.

                  (B) A participant shall not be eligible for and shall not be
entitled to receive a bonus for any fiscal year's performance unless the
participant is employed by the Company or one of its subsidiaries both on the
last day of the fiscal year and on the date of approval by the Committee of the
bonus (if a Level 1, 2 or 3 participant) or the aggregate employee bonus pool
for that year (if a Level 4 participant).

                  (C) The Committee, in its sole discretion, shall determine the
Level 1, Level 2 and Level 3 participants for any given fiscal year. Designation
of a manager as a participant for any fiscal year is in the absolute discretion
of the Company and the Committee and does not entitle that participant to remain
as a participant in any subsequent year.

                  (D) Addition, removal or movement of participants into, from
or between any of Levels 1, 2 or 3 must be submitted to and approved by the
Committee. The Level 1 managers, with the approval of the Chairman of the Board
and President, shall have discretion to add or remove participants at Level 4
without further action of the Committee, provided the aggregate bonuses paid to
all employees do not exceed the amount of the employee bonus pool for that year
approved by the Committee.

         5. ROA and EPS Calculation. The ROA and EPS for each fiscal year
(including 1998) shall be calculated using the asset and pre-tax income amounts
set forth on the audited annual financial statements of the Company for that
fiscal year and, when appropriate to the calculations, the internally generated
financial statements for each month and quarter of the fiscal year, prepared in
accordance with generally accepted accounting principles, with the following
adjustments:

                  (A) For all fiscal years, the following shall be excluded from
the calculation of assets: (i) cash; (ii) credit balances on accounts
receivable; (iii) deferred income taxes; (iv) deferred financing costs; and (v)
goodwill resulting from the acquisition of Amatek Holdings, Inc. and its
subsidiaries, including Metal Building Components, Inc. ("MBCI Goodwill").

                  (B) For fiscal years 1998 and 1999 only, the unamortized
investment in Midwest Metal Coatings, LLC shall be excluded from the calculation
of assets.

                  (C) For all fiscal years, interest expense shall be added back
to pre-tax income and income from investment of cash, if any, shall be deducted.

                  (D) For fiscal years 1998 and 1999 only, amortization and
depreciation of the MBCI Goodwill and of the investment in Midwest Metal
Coatings, LLC shall be added back to pre-tax income and the income or loss of
Midwest Metal Coatings, LLC shall be excluded.

If the Company conducts a public offering of equity securities, the Committee
will evaluate and determine at that time whether any adjustments should be made
to the calculation of EPS Growth.

         6.       Interpretation. The Committee shall interpret the Program and
shall prescribe such rules and regulations in connection with the operation of
the Program as it determines to be advisable. The Committee may rescind and
amend its rules, regulations and interpretations.

         7.       Amendment or Termination.  The Program may be terminated at
any time or amended from time to time by the Committee without the consent or
approval of the participants in the Program.

         8. Effect of Program. Neither the adoption of the Program nor any
action of the Committee, including action taken at any time to terminate or
amend the Program, shall be deemed to give any officer, manager, employee,
participant or other person any right to receive a bonus or any other rights,
whether as a third party beneficiary or otherwise.

         The NCI Nonqualified Stock Option Plan (amended and restated as of
December 12, 1996) (the "Plan") is hereby amended as follows:

         1.       Section 9 of the Plan is hereby restated in its entirety as
         follows:

                  9.       RIGHTS OF ESTATE OR BENEFICIARIES IN EVENT OF DEATH.
         If a participant dies prior to termination of his or her right to
         exercise an option in accordance with the provisions of the Plan or his
         or her stock option agreement without having totally exercised the
         option, the option may be exercised during the remainder of the Option
         Period by the participant's estate or by the person who acquired the
         right to exercise the option by bequest or by reason of the death of
         the participant, either pursuant to the laws of descent and
         distribution or by beneficiary designation; however, the option must be
         exercised prior to the date of expiration of the Option Period or one
         year from the date of the participant's death, whichever first occurs.
         The participant may designate a beneficiary to exercise an option
         pursuant to this Section 9 in the event of his or her death on a form
         designated by the Board for such purpose.

         2.       Section 13 of the Plan is hereby restated in its entirety as
         follows:

                  13.      NON-ASSIGNABILITY.  Options may not be transferred
         other than by will or by the laws of descent and distribution or by a
         beneficiary designation made by the participant. During a participant's
         lifetime, options granted to a participant may be exercised only by the
         participant.

         Signed to be effective the date first written above.
