                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT, made this 29th day of
January, 2003, is between NCI BUILDING SYSTEMS, L.P., a Texas limited
partnership (the "Company"), and JOHNIE SCHULTE (the "Employee").

         1. Employment Term. The Company hereby employs the Employee for a term
commencing on April 10, 1989 and ending on December 31, 1995, subject to earlier
termination as provided in Section 6 hereof, ending December 31, 1995 (such
term, as from time to time extended or earlier terminated as hereafter provided,
being herein referred to as the "term of this Agreement"). The Employee agrees
to accept such employment and to perform the services specified therein, all
upon the terms and conditions hereinafter stated. The term of this Agreement
shall be automatically renewed after December 31, 1995 for successive one-month
periods unless and until either party provides the other party with at least
thirty (30) days prior written notice of such party's intention to terminate
this Agreement.

         2. Duties. The Employee shall serve the Company in an executive
capacity and shall report to, and be subject to the general direction and
control of, the Board of Directors of the Company (the "Board"). The Employee
shall perform the executive, management and administrative duties of the
President and Chief Executive Officer of the Company and such other executive
duties as are from time to time assigned to him by the Board or such executive
officers and as are not inconsistent with the provisions hereof. The Company
agrees that it will assign the Employee those duties, and only those duties, of
the type, nature and dignity normally assigned to an officer of his position in
a corporation of the size, stature and nature of the Company.

         3. Extent of Service. The Employee shall devote his full business time
and attention to the business of the Company, and, except as may be specifically
permitted by the Board, shall not be engaged in any other business activity
during the term of this Agreement. The foregoing shall not be construed as
preventing the Employee from making passive investments in other businesses or
enterprises, provided, however, that such investments will not require services
on the part of the Employee which would in any way impair the performance of his
duties under this Agreement.

         4. Salary. The Company shall pay Employee a base salary of $125,000.00
per year. From time to time during the term of this Agreement, the Employee's
salary may be increased by, and at the sole discretion of, the Board, or any
committee thereof with responsibility for executive compensation matters, in
which case the amount of such increased salary shall thereafter be deemed to be
the amount of salary contracted for in this Agreement. The salary set forth
herein shall be payable in installments in accordance with the payroll policies
of the Company in effect from time to time during the term of this Agreement.

         5. Benefits. The Employee shall be eligible to receive those benefits
during the term of this Agreement that are from time to time applicable to
executive employees of the Company, together with any additional benefits
determined in the sole discretion of the Board, or any committee thereof with
responsibility for executive compensation matters.

         6. Termination.

                  (a) Death. If during the term of this Agreement and while in
the employ of the Company, the Employee dies, this Agreement shall automatically
terminate and the Company shall have no further obligation to the Employee or
his Beneficiary (as hereinafter defined) except that the Company shall pay the
Employee's Beneficiary (i) that portion of the Employee's salary accrued through
the end of the month in which the Employee's death occurred and (ii) the
Payments (as hereinafter defined) in the same manner and at the same times as if
the Employee had not died. If Employee's Beneficiary dies prior to the payment
of all of the Payments, the then present value of the remaining Payments shall
be paid to Beneficiary's estate in a single sum distribution within 30 days
after the date of Beneficiary's death.

                  (b) Disability. If during the term of this Agreement and while
in the employ of the Company, the Employee is prevented for sixty (60)
consecutive days or ninety (90) days in the aggregate from performing his duties
hereunder due to disability, this Agreement shall automatically terminate and
the Company shall have no further obligation to the Employee or his Beneficiary
except that the Company shall pay the Employee (i) that portion of the
Employee's salary accrued through the end of the month in which the Board's
determination of disability occurred and (ii) the Payments in the same manner
and at the same times as if the Employee had not become disabled if, on each
payment date, Employee has not breached or violated any of his covenants set
forth in Section 8(a). For purposes of this Agreement, the Employee shall be
deemed to have become disabled when the Board, upon the advice of a qualified
physician, shall have determined that the Employee has become physically or
mentally incapable (excluding infrequent and temporary absences due to ordinary
illness) of performing his duties under this Agreement.

                  (c) Termination for Cause. Notwithstanding any other provision
of this Agreement to the contrary, if Employee's employment with the Company is
terminated for Cause, this Agreement shall automatically terminate, the Company
shall have no further obligation to the Employee other than to pay the Employee
his base salary accrued through the date of termination and Employee shall
forfeit his or her rights to any other benefits under this Agreement.

                  (d) Involuntary Discharge. At any time during the term of this
Agreement or prior to the end of the term of this Agreement, the Company may
discharge the Employee without Cause, in which case this Agreement shall
automatically terminate and the Company shall have no further obligation to the
Employee or his Beneficiary other than (i) to pay the Employee his base salary
accrued through the date of such termination and (ii) the Payments in the same
manner and at the same times as if the Employee's employment had not been
terminated if, on each payment date, Employee has not breached or violated any
of his covenants set forth in Section 8(a).

                  (e) Voluntary Termination. The Employee may voluntarily
terminate his employment with the Company at any time during the term of this
Agreement, in which case this Agreement shall automatically terminate and the
Company shall have no further obligation to the Employee or his Beneficiary
other than (i) to pay the Employee his base salary accrued through the date of
such termination and (ii) the Vested Payments (as hereinafter defined) in the
amount and manner described in subsection (g) below.

                  (f) Payments. If Employee dies, becomes disabled or Employee's
employment is terminated by the Company for any reason other than Cause, then
for the

Amended and Restated Employment Agreement - Johnie Schulte                Page 2

<PAGE>

following three-year period, the Company shall pay to the Employee an annual
amount equal to 75% of the Employee's base salary in effect as of the date of
termination of Employee's employment with the Company and the Company shall
continue the Employee's participation in the Company's group health insurance
program (if so requested by the Employee) on the same terms applicable to his on
the date of discharge. Such amounts shall be paid to the Employee in the same
manner and at the same times (in accordance with the Company's then existing
payroll practices) as if the Employee had not died, became disabled or
Employee's employment had not terminated (collectively, the "Payments"). If
Employee dies prior to receiving all of the Payments and prior to his death had
not breached or violated any of his covenants set forth in Section 8(a),
Employee's Beneficiary shall receive the unpaid portion of Employee's Payments
during the remainder of the three-year period. Notwithstanding any other
provision of this Agreement to the contrary, if Employee breaches or violates
any of his covenants set forth in Section 8(a), Employee immediately shall
forfeit his or her rights to any remaining Payments.

                  (g) Vested Payments. If the Employee voluntarily terminates
his employment with the Company, then for the following three-year period, the
Company shall pay to the Employee an annual amount equal to 25%, 50% or 75% of
the Employee's base salary in effect as of the date of termination of Employee's
employment with the Company, dependent upon the amount vested as provided in
this subsection. Such amounts shall be paid to the Employee in the same manner
and at the same times (in accordance with the Company's then existing payroll
practices) as if the Employee had not voluntarily terminated his employment with
the Company (collectively, the "Vested Payments"). Employee's right to receive
amounts under this subsection shall vest over a period of three (3) years, at
the rate of 33-1/3% for each year of employment by Employee after the date
hereof. If Employee dies prior to receiving all of the Vested Payments and prior
to his death had not breached or violated any of his covenants set forth in
Section 8(a), Employee's Beneficiary shall receive the unpaid portion of
Employee's Vested Payments during the remainder of the three-year period.
Notwithstanding any other provision of this Agreement to the contrary, if
Employee breaches or violates any of his covenants set forth in Section 8(a),
Employee immediately shall forfeit his or her rights to any remaining Vested
Payments.

                  (h) Cause. For purposes of this Agreement, "Cause" shall be
determined by the Board of Directors, in its sole and absolute discretion, and
means the occurrence of any or all of the following:

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

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

                           (iii) The failure or inability for any reason of
                  Employee to devote his full business time to the Company's
                  business.

                  (i) Present Value. 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

Amended and Restated Employment Agreement - Johnie Schulte                Page 3

<PAGE>

such payment became payable (i.e., the date of termination of Employee's
employment with the Company), but in no event shall such discount rate exceed
8%.

         7. Confidential Information. The Employee acknowledges that in the
course of his employment by the Company he has received and will receive certain
trade secrets, programs, lists of customers and other confidential information
and knowledge concerning the business of the Company (hereinafter collectively
referred to as "Information") which the Company desires to protect. The Employee
understands that the Information is confidential and he agrees not to reveal the
Information to anyone outside the Company so long as the confidential or secret
nature of the Information shall continue. The Employee further agrees that he
will at no time use the Information in competing with the Company or any
affiliate of the Company. Upon termination of this Agreement, the Employee shall
surrender to the Company all papers, documents, writings and other property
produced by him or coming into his possession by or through his employment or
relating to the Information and the Employee agrees that all such materials will
at all times remain the property of the Company.

         8. Restrictive Covenant.

                  (a) In the event of any termination of the Employee's
employment with the Company for any reason at any time during the term of this
Agreement, then for a period beginning on the date of such termination and
ending three (3) years following the date of such termination, the Employee
shall not engage, anywhere within a radius of 500 miles of any plant, mini-plant
or any other manufacturing facility owned or operated by the Company as of the
time of such termination (the "Territory"), as principal, agent, trustee or
through the agency of any corporation, partnership, association or agent or
agency, in the business of manufacturing or selling engineered building systems,
metal building components or any other business ancillary thereto (the
"Industry"), and the Employee shall not be the owner of more than 5% of the
outstanding capital stock of any corporation, or a member or employee of any
partnership or an owner or employee of any business that conducts a business in
the Territory within the Industry. During such period, the Employee further
agrees that he shall not, either directly or indirectly, through any person,
firm, association or corporation with which the Employee is now or may hereafter
become associated, cause or induce any present or future employee of the Company
(or its successors and assigns) or any of their affiliates to leave the employ
of the Company (or its successors and assigns) or any such affiliate to accept
employment with the Employee or with such person, firm, association or
corporation.

                  (b) The foregoing covenants in Section 8(a) shall not be held
invalid or unenforceable because of the scope of the territory or actions
subject thereto or restricted thereby, or the period of time within which such
agreement is operative; but any judgment of a court of competent jurisdiction
may define the maximum territory and actions subject to and restricted by
covenants Section 8(a) and the period of time during which such covenants are
enforceable; provided, however, that in the event that as a result of an action
being instituted against the Company by or on behalf of the Employee, a judgment
of a court of competent jurisdiction is entered against the Company decreasing
the period of time during which this Agreement is enforceable, the term of this
Agreement shall be similarly decreased.

                  (c) The Employee represents and warrants to the Company that
(i) the Employee has the full right, power and authority to enter into and
perform this Agreement, including (without limitation) the giving of the
covenants in Section 8(a), (ii) the Employee acknowledges the giving of fair and
adequate consideration for his covenants in Section 8(a), and that such
covenants are necessary to protect the business, operations and goodwill of the

Company and to attract investment in the Company, (iii) such covenants are not
oppressive to the Employee in any respect, and (iv) on the date hereof, the
Employee is not engaged in a common calling.

                           NCI BUILDING SYSTEMS, INC.
                       2003 LONG-TERM STOCK INCENTIVE PLAN

         1. PURPOSE. The purposes of the Plan are to attract and retain for the
Company and its Subsidiaries the best available personnel, to provide additional
incentives to Employees, Directors and Consultants, to increase their interest
in the Company's welfare, and to promote the success of the business of the
Company and its Subsidiaries.

         2. INCENTIVE AWARDS AVAILABLE UNDER THE PLAN. Awards granted under this
Plan may be (a) Incentive Stock Options, (b) Non-Qualified Stock Options, (c)
Restricted Stock Awards; (d) Stock Appreciation Rights; (e) Performance Share
Awards; and (f) Phantom Stock Awards.

         3. SHARES SUBJECT TO PLAN. Subject to adjustment pursuant to Section
12(a) hereof, the total amount of Common Stock with respect to which Awards may
be granted under the Plan shall not exceed 1,500,000. At all times during the
term of the Plan, the Company shall allocate and keep available such number of
shares of Common Stock as will be required to satisfy the requirements of
outstanding Awards under the Plan. The number of shares reserved for issuance
under the Plan shall be reduced only to the extent that shares of Common Stock
are actually issued in connection with the exercise or settlement of an Award.
Any shares of Common Stock covered by an Award (or a portion of an Award) that
is forfeited or canceled or that expires shall be deemed not to have been issued
for purposes of determining the maximum aggregate number of shares of Common
Stock which may be issued under the Plan and shall again be available for Awards
under the Plan. The shares to be delivered under the Plan shall be made
available from authorized but unissued shares of Common Stock or Common Stock
held in the treasury of the Company.

         4. ELIGIBILITY. Awards other than Incentive Stock Options may be
granted to Employees, Officers, Directors, and Consultants. Incentive Stock
Options may be granted only to Employees. The Committee in its sole discretion
shall select the recipients of Awards. A Grantee may be granted more than one
Award under the Plan, and Awards may be granted at any time or times during the
term of the Plan. The grant of an Award to an Employee, Officer, Director or
Consultant shall not be deemed either to entitle that individual to, or to
disqualify that individual from, participation in any other grant of Awards
under the Plan.

         5. LIMITATION ON INDIVIDUAL AWARDS. Any and all shares available for
Awards under the Plan may be awarded by way of Options, Restricted Stock Awards
or Stock Appreciation Rights (regardless of the form of payment) to any one
person. The maximum Fair Market Value, measured as of the date of the grant of
the Award, of any Awards (other than Options, Restricted Stock Awards and Stock
Appreciation Rights) that may be granted to any one person during any fiscal
year shall be $400,000, plus any consideration paid by that person for the
Award. The preceding sentences shall be applied in a manner which will permit
compensation generated under the Plan, where appropriate, to constitute
"performance-based" compensation for purposes of Section 162(m) of the Code.

         6. STOCK OPTIONS.

                  (a) Grant of Options. An Option is a right to purchase shares
of Common Stock during the option period for a specified exercise price. The
Committee shall determine whether each Option shall be granted as an Incentive
Stock Option or a Non-Qualified Stock

NCI Building Systems, Inc.
2003 Long-Term Stock Incentive Plan                                       Page 1

<PAGE>

Option and the provisions, terms and conditions of each Option including, but
not limited to, the vesting schedule, the number of shares of Common Stock
subject to the Option, the exercise price of the Option, the period during which
the Option may be exercised, repurchase provisions, forfeiture provisions,
methods of payment, and all other terms and conditions of the Option.

                  (b) Limitations on Incentive Stock Options. The aggregate Fair
Market Value (determined as of the date of grant of an Option) of Common Stock
which any Employee is first eligible to purchase during any calendar year by
exercise of Incentive Stock Options granted under the Plan and by exercise of
Incentive Stock Options granted under any other incentive stock option plan of
the Company or a Subsidiary shall not exceed $100,000. If the Fair Market Value
of stock with respect to which all Incentive Stock Options described in the
preceding sentence held by any one Optionee are exercisable for the first time
by such Optionee during any calendar year exceeds $100,000, the Options (that
are intended to be Incentive Stock Options on the date of grant thereof) for the
first $100,000 worth of shares of Common Stock to become exercisable in such
year shall be deemed to constitute Incentive Stock Options and the Options (that
are intended to be Incentive Stock Options on the date of grant thereof) for the
shares of Common Stock in the amount in excess of $100,000 that become
exercisable in that calendar year shall be treated as Non-Qualified Stock
Options. If the Code or the Treasury regulations promulgated thereunder are
amended after the effective date of the Plan to provide for a different limit
than the one described in this Section 6(b), such different limit shall be
incorporated herein and shall apply to any Options granted after the effective
date of such amendment.

                  (c) Acquisitions and Other Transactions. Notwithstanding the
provisions of Section 11(h), in the case of an Option issued or assumed pursuant
to Section 11(h), the exercise price and number of shares for the Option shall
be determined in accordance with the principles of Section 424(a) of the Code
and the Treasury regulations promulgated thereunder.

                  (d) Payment on Exercise. Payment for the shares of Common
Stock to be purchased upon exercise of an Option may be made in cash (by check)
or, if elected by the Optionee where permitted by law: (i) if a public market
for the Common Stock exists, through a "same day sale" arrangement between the
Optionee and a NASD Dealer whereby the Optionee elects to exercise the Option
and to sell a portion of the shares of Common Stock so purchased to pay for the
exercise price and whereby the NASD Dealer commits upon receipt of such shares
of Common Stock to forward the exercise price directly to the Company; (ii) if a
public market for the Common Stock exists, through a "margin" commitment from
the Optionee and an NASD Dealer whereby the Optionee elects to exercise the
Option and to pledge the shares of Common Stock so purchased to the NASD Dealer
in a margin account as security for a loan from the NASD Dealer in the amount of
the exercise price, and whereby the NASD Dealer commits upon receipt of such
shares of Common Stock to forward the exercise price directly to the Company;
(iii) by surrender for cancellation of Qualifying Shares at the Fair Market
Value per share at the time of exercise (provided that such surrender does not
result in an accounting charge for the Company); or (iv) where approved by the
Committee at the time of exercise, by delivery of the Optionee's promissory note
with such recourse, interest, security, redemption and other provisions as the
Committee may require, provided that the par value of each of the shares of
Common Stock to be purchased is paid for in cash. No shares of Common Stock may
be issued until full payment of the purchase price therefor has been made.

         7. RESTRICTED STOCK AWARDS.

                  (a) Restricted Stock Awards. A Restricted Stock Award is a
grant of shares of Common stock for such consideration, if any, and subject to
such restrictions on transfer, rights of first refusal, repurchase provisions,
forfeiture provisions and other terms and conditions as are established by the
Committee.

                  (b) Forfeiture Restrictions. Shares of Common Stock that are
the subject of a Restricted Stock Award shall be subject to restrictions on
disposition by the Grantee and to an obligation of the Grantee to forfeit and
surrender the shares to the Company under certain circumstances (the "Forfeiture
Restrictions"). The Forfeiture Restrictions shall be determined by the Committee
in its sole discretion, and the Committee may provide that the Forfeiture
Restrictions shall lapse on the passage of time, the attainment of one or more
performance targets established by the Committee, or the occurrence of such
other event or events determined to be appropriate by the Committee. The
Forfeiture Restrictions applicable to a particular Restricted Stock Award (which
may differ from any other such Restricted Stock Award) shall be stated in the
Restricted Stock Agreement.

                  (c) Rights as Stockholder. Shares of Common Stock awarded
pursuant to a Restricted Stock Award shall be represented by a stock certificate
registered in the name of the Grantee of such Restricted Stock Award. The
Grantee shall have the right to receive dividends with respect to the shares of
Common Stock subject to a Restricted Stock Award, to vote the shares of Common
Stock subject thereto and to enjoy all other stockholder rights with respect to
the shares of Common Stock subject thereto, except that, unless provided
otherwise in this Plan, or in the Restricted Stock Agreement, (i) the Grantee
shall not be entitled to delivery of the shares of Common Stock except as the
Forfeiture Restrictions expire, (ii) the Company or an escrow agent shall retain
custody of the shares of Common Stock until the Forfeiture Restrictions expire,
(iii) the Grantee may not sell, transfer, pledge, exchange, hypothecate or
otherwise dispose of the shares of Common Stock until the Forfeiture
Restrictions expire.

                  (d) Stock Certificate Delivery. One or more stock certificates
representing shares of Common Stock, free of Forfeiture Restrictions, shall be
delivered to the Grantee promptly after, and only after, the Forfeiture
Restrictions have expired. The Grantee, by his or her acceptance of the
Restricted Stock Award, irrevocably grants to the Company a power of attorney to
transfer any shares so forfeited to the Company, agrees to execute any documents
requested by the Company in connection with such forfeiture and transfer, and
agrees that such provisions regarding transfers of forfeited shares shall be
specifically performable by the Company in a court of equity or law.

                  (e) Payment for Restricted Stock. The Committee shall
determine the amount and form of any payment for shares of Common Stock received
pursuant to a Restricted Stock Award. In the absence of such a determination,
the Grantee shall not be required to make any payment for shares of Common Stock
received pursuant to a Restricted Stock Award, except to the extent otherwise
required by law.

                  (f) Forfeiture of Restricted Stock. Unless otherwise provided
in a Restricted Stock Agreement, on termination of the Grantee's employment or
service prior to lapse of the Forfeiture Restrictions, the shares of Common
Stock which are still subject to the Restricted Stock Award shall be forfeited
by the Grantee. Upon any forfeiture, all rights of the Grantee with respect to
the forfeited shares of the Common Stock subject to the Restricted Stock Award
shall

2003 Long-Term Stock Incentive Plan                                       Page 3

<PAGE>

cease and terminate, without any further obligation on the part of the Company
except to repay any purchase price per share paid by the Grantee for the shares
forfeited.

                  (g) Waiver of Forfeiture Restrictions; Committee's Discretion.
With respect to a Restricted Stock Award that has been granted to a Covered
Employee where such Award has been designed to meet the exception for
performance-based compensation under Section 162(m) of the Code, the Committee
may not waive the Forfeiture Restrictions applicable to such Restricted Stock
Award.

         8. STOCK APPRECIATION RIGHTS.

                  (a) Stock Appreciation Rights. A Stock Appreciation Right is a
right to receive, upon exercise of the right, shares of Common Stock or their
cash equivalent in an amount equal to the increase in Fair Market Value of the
Common Stock between the grant and exercise dates.

                  (b) Tandem Rights. Stock Appreciation Rights may be granted in
connection with the grant of an Option, in which case exercise of Stock
Appreciation Rights will result in the surrender of the right to purchase the
shares under the Option as to which the Stock Appreciation Rights were
exercised. Alternatively, Stock Appreciation Rights may be granted independently
of Options in which case each Award of Stock Appreciation Rights shall be
evidenced by a Stock Appreciation Rights Agreement. With respect to Stock
Appreciation Rights that are subject to Section 16 of the Exchange Act, the
Committee shall retain sole discretion (i) to determine the form in which
payment of the Stock Appreciation Right will be made (i.e., cash, securities or
any combination thereof) or (ii) to approve an election by a Grantee to receive
cash in full or partial settlement of Stock Appreciation Rights. The number of
shares reserved for issuance under the Plan shall be reduced only to the extent
that shares of Common Stock are actually issued in connection with the exercise
or settlement of an Award.

                  (c) Limitations on Exercise of Stock Appreciation Rights. A
Stock Appreciation Right shall be exercisable in whole or in such installments
and at such times as determined by the Committee.

         9. PERFORMANCE SHARE AWARDS.

                  (a) Performance Share Awards. A Performance Share Award is a
right to receive shares of Common Stock or their cash equivalent based on the
attainment of pre-established performance goals and such other conditions,
restrictions and contingencies as the Committee shall determine. Each
Performance Share Award may have a maximum value established by the Committee at
the time of such Award.

                  (b) Performance Period. The Committee shall establish, with
respect to and at the time of each Performance Share Award, a performance period
or periods over which the performance applicable to the Performance Share Award
of the Grantee shall be measured.

                  (c) Performance Measures. A Performance Share Award may be
awarded to an Employee contingent upon future performance of the Grantee, the
Company or any Subsidiary, division or department thereof by or in which he is
employed or performing services during the performance period or periods,
combinations thereof, or such other provisions as the Committee may determine to
be appropriate. The Committee shall establish the performance

                                       22
<PAGE>

measures applicable to such performance prior to the beginning of any
performance period but subject to such later revisions as the Committee shall
deem appropriate to reflect significant, unforeseen events or changes.

                  (d) Payment. Following the end of any performance period, the
Grantee of a Performance Share Award shall be entitled to receive payment of an
amount, not exceeding the maximum value of the Performance Share Award, if any,
based on the achievement of the performance measures for such performance
period, as determined by the Committee in its sole discretion.

                  (e) Termination of Employment. The Committee shall determine
the effect of termination of employment or service during the performance period
on a Grantee's Performance Share Award, which shall be set forth in the Award
Agreement.

         10. PHANTOM STOCK AWARDS.

                  (a) Phantom Stock Awards. Phantom Stock Awards are rights to
receive an amount equal to the Fair Market Value of shares of Common Stock or
rights to receive an amount equal to any appreciation or increase in the Fair
Market Value of the Common Stock over a specified period of time, which may vest
over a period of time as established by the Committee, without payment of any
amounts by the Grantee thereof (except to the extent otherwise required by law)
or satisfaction of any performance criteria or objectives. Each Phantom Stock
Award may have a maximum value established by the Committee at the time of such
Award.

                  (b) Award Period. The Committee shall establish, at the time
of grant of each Phantom Stock Award, a period over which the Award shall vest
with respect to the Grantee.

                  (c) Payment. Following the end of the determined period for a
Phantom Stock Award, the Grantee of a Phantom Stock Award shall be entitled to
receive payment of an amount, not exceeding the maximum value of the Phantom
Stock Award, if any, based on the then vested value of the Award. Cash dividend
equivalents may be paid during or may be accumulated and paid at the end of, the
determined period with respect to a Phantom Stock Award, as determined by the
Committee.

         11. GENERAL PROVISIONS REGARDING AWARDS.

                  (a) Form of Award Agreement. Each Award granted under the Plan
shall be evidenced by a written Award Agreement in such form (which need not be
the same for each Grantee) as the Committee from time to time approves but which
is not inconsistent with the Plan, including any provisions that may be
necessary to assure that any Option that is intended to be an Incentive Stock
Option will comply with Section 422 of the Code.

                  (b) Awards Criteria. In determining the amount and value of
Awards to be granted, the Committee may take into account the responsibility
level, performance, potential, other Awards and such other considerations with
respect to a Grantee as it deems appropriate.

                  (c) Date of Grant. The date of grant of an Award will be the
date specified by the Committee as the effective date of the grant of an Award
or, if the Committee does not so specify, will be the date on which the
Committee makes the determination to grant such Award.

<PAGE>

                  (d) Stock Price. The exercise price or other measurement of
stock value relative to any Award shall be not less than 100% of the Fair Market
Value of the shares of Common Stock for the date of grant of the Award. The
exercise price of any Incentive Stock Option granted to a Ten Percent
Shareholder shall not be less than 110% of the Fair Market Value of the shares
of Common Stock for the date of grant of the Option.

                  (e) Period of Award. Awards shall be exercisable or payable
within the time or times or upon the event or events determined by the Committee
and set forth in the Award Agreement. Unless otherwise provided in an Award
Agreement, Awards other than Restricted Stock Awards shall terminate on (and no
longer be exercisable or payable after) the earlier of: (i) ten (10) years from
the date of grant; (ii) for an Incentive Stock Option granted to a Ten Percent
Shareholder, five (5) years from the date of grant of the Option; (iii) the 30th
day after the Grantee is no longer serving in any capacity as an Employee,
Consultant or Director of the Company for a reason other than death of the
Grantee, Disability or retirement at or after the Normal Retirement Age; (iv)
one year after death; or (v) one year (with respect to an Incentive Option) or
five years (with respect to any other Award) after Disability of the Grantee or
after his or her retirement at or after the Normal Retirement Age from any
capacity as an Employee, Consultant or Director of the Company.

                  (f) Acceleration of Vesting or Lapse of Restrictions. If the
Grantee dies or becomes Disabled while serving as an Employee, Consultant or
Director of the Company or retires at or after Normal Retirement Age, or if
there occurs a Change in Control, then 100% of the benefits dependent upon lapse
of time will become vested, all Forfeiture Restrictions and other forfeiture and
repurchase provisions will lapse and, subject to meeting any performance or
other criteria for such Award, such benefits will be available thereafter for
purchase or payment during the Award term.

                  (g) Transferability. Awards granted under the Plan, and any
interest therein, shall not be transferable or assignable by the Grantee, and
may not be made subject to execution, attachment or similar process, otherwise
than by will or by the laws of descent and distribution, and shall be
exercisable or payable during the lifetime of the Grantee only by the Grantee;
provided, that the Grantee may designate persons who or which may exercise or
receive his Awards following his death. Notwithstanding the preceding sentence,
Awards other than Incentive Stock Options may be transferred to such family
members, family member trusts, family limited partnerships and other family
member entities as the Committee, in its sole discretion, may approve prior to
any such transfer. No such transfer will be approved by the Committee if the
Common Stock issuable under such transferred Award would not be eligible to be
registered on Form S-8 promulgated under the Securities Act.

                  (h) Acquisitions and Other Transactions. The Committee may,
from time to time, approve the assumption of outstanding awards granted by
another entity, whether in connection with an acquisition of such other entity
or otherwise, by either (i) granting an Award under the Plan in replacement of
or in substitution for the awards assumed by the Company, or (ii) treating the
assumed award as if it had been granted under the Plan if the terms of such
assumed award could be applied to an Award granted under the Plan. Such
assumption shall be permissible if the holder of the assumed award would have
been eligible to be granted an Award hereunder if the other entity had applied
the rules of this Plan to such grant.

<PAGE>

                  (i) Payment. Payment of an Award (i) may be made in cash,
Common Stock or a combination thereof, as determined by the Committee in its
sole discretion, (ii) shall be made in a lump sum or in installments as
prescribed by the Committee in its sole discretion and (iii) to the extent
applicable, shall be based on the Fair Market Value of the Common Stock for the
payment or exercise date. The Committee may permit or require the deferral of
payment, subject to such rules and procedures as it may establish, which may
include provisions for the payment or crediting of interest, dividend
equivalents or other forms of investment return.

                  (j) Notice. If an Award involves an exercise, it may be
exercised only by delivery to the Company of a written exercise notice approved
by the Committee, stating the number of shares of Common Stock being exercised,
the method of payment, and such other matters as may be deemed appropriate by
the Company in connection with the issuance of shares upon exercise, together
with payment in full of any exercise price for any shares being purchased.

                  (k) Withholding Taxes. The Committee may establish such rules
and procedures as it considers desirable in order to satisfy any obligation of
the Company to withhold the statutory prescribed minimum amount of federal or
state income taxes or other taxes with respect to any Award granted under the
Plan. Prior to issuance of any shares of Common Stock, the Grantee shall pay or
make adequate provision acceptable to the Committee for the satisfaction of the
statutory minimum prescribed amount of any federal or state income or other tax
withholding obligations of the Company, if applicable. Upon exercise or payment
of an Award, the Company shall withhold or collect from the Grantee an amount
sufficient to satisfy such tax withholding obligations.

                  (l) Limitations on Exercise. The obligation of the Company to
issue any shares of Common Stock or otherwise make payments hereunder shall be
subject to the condition that any exercise and the issuance and delivery of such
shares and other actions pursuant thereto comply with the Securities Act, all
applicable state securities and other laws and the requirements of any stock
exchange or national market system upon which the shares of Common Stock may
then be listed or quoted, as in effect on the date of exercise. The Company
shall be under no obligation to register the shares of Common Stock with the
Securities and Exchange Commission or to effect compliance with the
registration, qualification or listing requirements of any state securities laws
or stock exchange or national market system, and the Company shall have no
liability for any inability or failure to do so.

                  (m) Privileges of Stock Ownership. Except as provided in the
Plan with respect to Restricted Stock Awards, no Grantee will have any of the
rights of a shareholder with respect to any shares of Common Stock subject to an
Award until such Award is properly exercised and the purchased or awarded shares
are issued and delivered to the Grantee, as evidenced by an appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company.
No adjustment shall be made for dividends or distributions or other rights for
which the record date is prior to such date of issuance and delivery, except as
provided in the Plan.

                  (n) Breach; Additional Terms. A breach of the terms and
conditions of this Plan or established by the Committee pursuant to the Award
Agreement shall cause a forfeiture of the Award. At the time of such Award, the
Committee may, in its sole discretion, prescribe additional terms, conditions or
restrictions relating to the Award, including provisions pertaining to the
termination of the Grantee's employment (by retirement, Disability, death or
otherwise)

NCI Building Systems, Inc.
2003 Long-Term Stock Incentive Plan                                       Page 7

prior to expiration of the Forfeiture Restrictions or other vesting provisions.
Such additional terms, conditions or restrictions shall also be set forth in an
Award Agreement made in connection with the Award.

                  (o) Performance-Based Compensation. The Committee may
designate any Award as "qualified performance-based compensation" for purposes
of Section 162(m) of the Code. Any Awards designated as "qualified
performance-based compensation" shall be conditioned on the achievement of any
one or more Performance Criteria, and the measurement may be stated in absolute
terms or relative to individual performances, comparable companies, peer or
industry groups or other standard indexes, and in terms of company-wide
objectives or in terms of absolute or comparative objectives that relate to the
performance of divisions, affiliates, departments or functions within the
company or an affiliate. Notwithstanding any other provision of the Plan, the
Committee may grant an Award that is not contingent on performance goals or is
contingent on performance goals other than the Performance Criteria, so long as
the Committee has determined that such Award is not intended to satisfy the
requirements for "qualified performance-based compensation" within the meaning
of Section 162(m) of the Code.

         12. ADJUSTMENT UPON CHANGES IN CAPITALIZATION AND CORPORATE EVENTS.

                  (a) Capital Adjustments. The number of shares of Common Stock
(i) covered by each outstanding Award granted under the Plan, the exercise,
target or purchase price of such outstanding Award, and any other terms of the
Award that the Committee determines requires adjustment and (ii) available for
issuance under Section 3 shall be adjusted to reflect, as deemed appropriate by
the Committee, any increase or decrease in the number of shares of Common Stock
resulting from a stock dividend, stock split, reverse stock split, combination,
reclassification or similar change in the capital structure of the Company
without receipt of consideration, subject to any required action by the Board or
the shareholders of the Company and compliance with applicable securities laws;
provided, however, that a fractional share will not be issued upon exercise of
any Award, and either (i) any fraction of a share of Common Stock that would
have resulted will be cashed out at Fair Market Value or (ii) the number of
shares of Common Stock issuable under the Award will be rounded up to the
nearest whole number, as determined by the Committee.

                  (b) Change in Control. Unless specifically provided otherwise
with respect to Change in Control events in an individual Award or Award
Agreement or in a then-effective written employment agreement between the
Grantee and the Company or a Subsidiary, if, during the effectiveness of the
Plan, a Change in Control occurs, (i) each Award which is at the time
outstanding under the Plan shall automatically become fully vested and
exercisable or payable, as appropriate, and be released from any repurchase or
forfeiture provisions, for all of the shares of Common Stock at the time
represented by such Award, (ii) the Forfeiture Restrictions applicable to all
outstanding Restricted Stock Awards shall lapse and shares of Common Stock
subject to such Restricted Stock Awards shall be released from escrow, if
applicable, and delivered to the Grantees of the Awards free of any Forfeiture
Restriction, and (iii) all other Awards shall become fully vested and payment
thereof shall be accelerated using, if applicable, the then-current Fair Market
Value to measure any payment that is based on the value of the Common Stock or
using such higher amount as the Committee may determine to be more reflective of
the actual value of such stock.

         13. STOCKHOLDER APPROVAL. The Company shall obtain the approval of the
Plan by the Company's stockholders at the next annual meeting following its
adoption by the Board, and no Awards shall be made hereunder unless and until
such approval is obtained.

         14. ADMINISTRATION. This Plan shall be administered by the Committee.
The Committee shall interpret the Plan and any Awards granted pursuant to the
Plan and shall prescribe such rules and regulations in connection with the
operation of the Plan as it determines to be advisable for the administration of
the Plan. The Committee may rescind and amend its rules and regulations from
time to time. The interpretation by the Committee of any of the provisions of
this Plan or any Award granted under this Plan shall be final and binding upon
the Company and all persons having an interest in any Award or any shares of
Common Stock or other payments received pursuant to an Award.

         15. EFFECT OF PLAN. Neither the adoption of the Plan nor any action of
the Board or the Committee shall be deemed to give any Employee, Director or
Consultant any right to be granted an Award or any other rights except as may be
evidenced by the Award Agreement, or any amendment thereto, duly authorized by
the Committee and executed on behalf of the Company, and then only to the extent
and on the terms and conditions expressly set forth therein. The existence of
the Plan and the Awards granted hereunder shall not affect in any way the right
of the Board, the Committee or the stockholders of the Company to make or
authorize any adjustment, recapitalization, reorganization or other change in
the Company's capital structure or its business, any merger or consolidation or
other transaction involving the Company, any issue of bonds, debentures, or
shares of preferred stock ranking prior to or affecting the Common Stock or the
rights thereof, the dissolution or liquidation of the Company or any sale or
transfer of all or any part of the Company's assets or business, or any other
corporate act or proceeding by or for the Company. Nothing contained in the Plan
or in any Award Agreement or in other related documents shall confer upon any
Employee, Director or Consultant any right with respect to such person's service
or interfere or affect in any way with the right of the Company or a Subsidiary
to terminate such person's employment or service at any time, with or without
cause.

         16. NO EFFECT ON RETIREMENT AND OTHER BENEFIT PLANS. Except as
specifically provided in a retirement or other benefit plan of the Company or a
Subsidiary, Awards shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Company or a
Subsidiary, and shall not affect any benefits under any other benefit plan of
any kind or any benefit plan subsequently instituted under which the
availability or amount of benefits is related to level of compensation.

         17. AMENDMENT OR TERMINATION OF PLAN. The Board in its discretion may,
at any time or from time to time after the date of adoption of the Plan,
terminate or amend the Plan in any respect, including amendment of any form of
agreement or instrument to be executed pursuant to the Plan; provided, however,
to the extent necessary to comply with the Code, including Sections 162(m) and
422 of the Code, other applicable laws and regulations, or the applicable
requirements of any stock exchange or national market system, the Company shall
obtain stockholder approval of any Plan amendment in such manner and to such a
degree as required. No Award may be granted after termination of the Plan. Any
amendment or termination of the Plan shall not adversely affect Awards
previously granted, and such Awards shall otherwise remain in full force and
effect as if the Plan had not been amended or terminated, unless mutually agreed
otherwise in a writing signed by the Grantee and the Company.
