     THIS EMPLOYMENT AGREEMENT (this “Agreement”) is entered into as of April

“Company”), and its wholly-owned subsidiary, NCI Group, L.P., a Texas limited
partnership (“Employer”), and Norman C. Chambers, a resident of the State of
Texas (“Employee”).

BACKGROUND

     Employer hires and retains in its employment such personnel as are required
by the Company and its other Affiliates, and makes its employees so retained
available to provide services to the Company and its Affiliates.

     The Company desires that Employer hire Employee and make him available to
serve as the President and Chief Operating Officer of the Company, and Employee
desires to be so employed by the Employer and to serve as the President and
Chief Operating Officer of the Company.

     This Agreement sets forth the terms and conditions of the employment of
Employee by Employer, and the duties and responsibilities of Employee, on the
one hand, and of the Employer and the Company, on the other hand, to each other.

     Capitalized terms not defined in the body of this Agreement have the
meanings set forth in Appendix A.

AGREEMENT AMONG PARTIES

     In consideration of the foregoing and of the mutual covenants and
agreements set forth in this Agreement, and subject to the terms and conditions
set forth herein, the parties agree as follows:

     1. Employment. Employer hereby employs Employee, and Employee hereby
accepts employment with Employer and agrees to serve the Company in the
capacities and with the authority and duties set forth herein.

     2. Services.

          (a) Capacities.

               (i) Employee shall serve in the capacity of President and Chief
Operating Officer and continue to serve as a director of the Company. Employee
also shall from time to time, as requested by the Company, serve as a director
or executive officer of one or more of the Affiliates of the Company.

               (ii) It is intended that Employee serve as a director of the

continue to nominate Employee for re-election from time to time as a member of
the Board of Directors of the Company and to recommend such nomination to the
stockholders of the Company for their approval.

          (b) Authority. In his capacity as President and Chief Operating
Officer of the Company, Employee shall have all of the explicit, implicit and
apparent powers and authority granted by the By-Laws of the Company to the
President and Chief Operating Officer, subject to any limitations thereon from
time to time imposed by the Board of Directors of the Company. Unless expressly
prohibited by its By-Laws or by orders or resolutions of its Board of Directors,

law to the offices of president and chief operating officer of a company.
Employee shall report directly to the Chairman of the Board and Chief Executive
Officer of the Company.

devote substantially all of his business time and effort to the performance of
his duties and responsibilities as President and Chief Operating Officer of the
Company and as an executive officer or director of Affiliates of the Company.
Employee shall use his commercially reasonable efforts to preserve the business
of the Company and its Affiliates, as well as the goodwill of employees,
customers, suppliers and other persons having business relations with the
Company and its Affiliates. Notwithstanding the foregoing, Employee may spend
reasonable amounts of time on charitable, civic, personal and investment
activities, provided the same do not interfere with the performance of his
duties and responsibilities to the Company and its Affiliates.

     3. Compensation.

          (a) Salary. Employer shall pay Employee a base salary of not less than
$400,000 a year, payable in accordance with Employer’s normal payroll procedures
and subject to all appropriate withholdings. The salary of Employee will be
reviewed at least once annually by the Compensation Committee of the Board of
Directors of the Company, such review to be conducted by the Compensation
Committee at the same time as it reviews the salaries of other senior executives
of the Company, and any adjustment shall be solely within the discretion of the
Compensation Committee of the Board of Directors of the Company; provided,
however, that no adjustment shall reduce the then current base salary of
Employee by more than ten percent (10%) in any twelve-month period, or below
$400,000 a year.

          (b) Annual Bonus. Employee shall be a Level I participant under the
currently existing Bonus Program of the Company or, if it be amended, replaced
or superceded, at the most senior level under any amended, replacement or
successor bonus program adopted for executive officers of the Company and its
Affiliates. Employee’s annual bonus, if any, under the Bonus Program for fiscal
2004 will be prorated for the number of days of Employee’s employment during
fiscal 2004. Bonuses, if any, paid to Employee pursuant to the Bonus Program
shall be paid after the end of each fiscal year of the Company at the same time
as the same are paid to other participants, and shall be subject to required
withholding under applicable tax laws. Employee understands that bonuses cannot
be earned under the Bonus Program unless a participant meets the requirements
set forth in the Bonus Program and, if the employment of a participant
terminates for any reason prior to certain dates specified in the Bonus Program,
no bonus shall be payable

2

--------------------------------------------------------------------------------

 

thereunder. Employee also understands that the Bonus Program may be amended,
replaced, superceded or terminated at any time and from time to time by the
Board of Directors in its sole discretion.

          (c) Lump Sum Payment. In consideration of certain benefits that
Employee will forego under the terms of his employment with his immediate past
employer, on the Employment Date, Employer shall pay to employee a one-time lump

200,000 shares of Common Stock of the Company, which options shall have an
expiration date ten years from the date of grant of the options and be evidenced
by a Nonqualified Stock Option Agreement in the form attached hereto as

Company’s currently existing semi-annual policy for the grant of options and/or
restricted stock under the 2003 Plan, commencing with the grant of options
and/or restricted stock on June 15, 2004. Employee understands that the option
and/or restricted stock awards under the 2003 Plan are made in the sole
discretion of the Compensation Committee of the Board of Directors, and that the
policy of making semi-annual grants thereunder may be amended, replaced,
superceded or terminated at any time by the Board of Directors or Compensation
Committee, in its sole discretion.

               (i) On the Employment Date, the Company shall issue to Employee
under the 2003 Plan a Restricted Stock Award (as defined in the 2003 Plan) of
50,000 shares of Common Stock of the Company, which Restricted Stock Award shall

for senior executives of the Company by the Compensation Committee of the Board
of Directors, a copy of which is attached hereto as Attachment B.

          (f) Health and Welfare Benefits. Employee shall be entitled to
participate in and receive the health, hospitalization, medical, dental, life
insurance, accidental death, disability and other insurance, plans and benefits
provided by Employer and the Company, and to participate in the 401(k) and other
qualified profit-sharing, pension, savings and other similar plans of Employer
and the Company, as and to the extent Employer and the Company provides such

discretion of Employer and the Company.

     4. Term.

          (a) Employment Term; Commencement of Employment. Employee shall
commence his employment with Employer and the Company on such date as the
parties hereto mutually agree, but not later than May 15, 2004. The date on
which Employee’s employment with Employer and the Company actually commences is
referred to herein as the “Employment Date”. Employee’s employment shall
commence on the Employment Date and continue until April 30, 2014, the last day
of the month in which Employee attains the age of 65 (the “Employment Term”),
unless earlier terminated in accordance with this Agreement.

          (b) Early Termination Notwithstanding the provisions of subsection (a)
above, either the Company or Employee may terminate his employment with the
Company, Employer and their Affiliates at any time, with or without Cause or
Good Reason, upon written notice by the terminating party to the other party.
Such termination of employment shall be effective on the date specified in such
notice, but shall be not earlier than thirty (30) days after the date of the
notice if the termination is by the Company or Employer without Cause or by
Employee without Good Reason. Nothing contained herein shall be deemed to
abrogate the obligation of the Company or Employee to give any required notice
and opportunity to cure an act or omission it or he believes

4

--------------------------------------------------------------------------------

 

constitute Cause or Good Reason to terminate employment, if otherwise required
to be given as set forth in the definitions of those terms set forth elsewhere
herein.

          (c) Continuation Beyond Employment Term. If the employment of Employee
is continued after the expiration of this Agreement, his employment shall be on
such terms and conditions as may be expressly agreed to from time to time by
Employer, the Company and Employee. If Employer continues to employ Employee
after the expiration of this Agreement and if Employer, the Company and Employee
do not expressly agree to terms and conditions of Employee’s employment
following expiration of this Agreement, Employee’s employment with Employer
shall continue under the terms and conditions of this Agreement on a
month-to-month basis and either Employer, the Company or Employee may terminate
such month-to-month employment and any obligations hereunder at any time upon
thirty (30) days’ prior notice to other party.

     5. Termination Payments.

          (a) Minimum Termination Compensation. Upon any termination of
employment of Employee, whether on, before or after the expiration of the term
of this Agreement (including any continuation of employment on a month-to-month
basis subject to the terms of this Agreement), Employee shall be entitled to
receive that portion of his annual base salary, at the rate then in effect,
earned by him or accrued for his account through the date of the termination of
his employment hereunder, and all fringe benefits that were earned by him or
accrued for his benefit, or for which he is entitled to payment for events or
circumstances occurring on or through the date of termination of his employment.

          (b) Additional Payments for Certain Terminations. If Employee’s
employment is terminated by the Company without Cause or by Employee for Good
Reason, Employee shall be entitled to receive, in addition to those amounts and
other benefits set forth in subsection (a) above, severance payments equal in
the aggregate to the amount of his annual base salary, at the rate then in
effect, that would have been paid to him from the date of termination of his
employment through the end of the Employment Term, if his employment had
continued through that date. The severance payments shall be paid to Employee in
equal installments on the normal employee pay days of Employer until the end of
the Employment Term, as if his employment had continued through that date. Each
installment shall be in the same amount as the gross pay that would have been
payable to Employee on that pay day had his employment not been terminated, less
any required withholding under applicable tax laws.

          (c) Payment Following a Change in Control.

               (i) Notwithstanding the provisions of Section 5(b), if Employee’s
employment is terminated by the Company without Cause or by Employee for Good
Reason within two years after a Change in Control, then the Employee shall be
entitled to receive, within seven (7) days after termination, the present value
of the payments otherwise due under Section 5(b) in the form of a lump sum
payment of cash. For purposes of this Agreement, the Company shall calculate the
present value of such amount using a discount rate equal to the longest-term
LIBOR rate

5

--------------------------------------------------------------------------------

 

reported by The Wall Street Journal on the date on which such payment became
payable (i.e., the date of termination of Employee’s employment with the
Company) plus two percent (2%).

               (ii) Notwithstanding anything in this Agreement to the contrary,
if any amounts due to Employee under this Agreement and any other plan or
program or award of Employer, the Company or any Affiliate constitute a
“parachute payment,” as such term is defined in § 280G(b)(2) of the Internal
Revenue Code of 1986, as amended (the “Code”), and the amount of the parachute
payment, reduced by the excise tax imposed pursuant to § 4999 of the Code, is
less than the amount Employee would receive if he were paid three times his
“base amount,” as defined in § 280G(b)(3) of the Code, less one dollar, then the
aggregate of the amounts constituting the parachute payment shall be reduced to
an amount that will equal three times his base amount less one dollar. Employee,
in his sole discretion, shall determine the manner in which any reduction
pursuant to this subsection shall be applied to the amounts constituting a part
of the parachute payment. The calculations to be made with respect to this
subsection shall be made by an accounting firm jointly selected by the Company
and Employee and paid by the Company.

          (d) Termination by Death. In the event of Employee’s death, Employee’s
employment will terminate as of the date of Employee’s death and the estate of
Employee will be entitled to receive only the amounts specified in Section 5(a)
hereof.

          (e) Duty to Mitigate. If Employee’s employment is terminated by the
Company without Cause or by Employee for Good Reason before Employee attains the
age of 60, Employee shall, until he reaches the age of 60, use commercially
reasonable efforts to mitigate damages by seeking other employment (whether as
an employee, independent contractor, agent or otherwise). In seeking such other
employment, Employee shall only be required to seek employment of a type
appropriate for Employee’s background and abilities, and Employee shall not be
required to accept a position of substantially less dignity and importance or of
substantially different character than he held with the Company and Employer at
the time of termination and, without the prior written approval of the Company,
he shall not accept a position that would or might require him to engage in
competition with the Company and its Affiliates in violation of Section 7 of
this Agreement. Promptly upon acceptance of employment with another party,
Employee shall furnish the Company and Employer with evidence of salary and
benefits earned or to be by him and, from time to time thereafter if and as his
salary, benefits or employment relationships change, Employee shall promptly
provide evidence of such changed salary and benefits earned or to be earned by
him. To the extent that Employee receives compensation from other employment
during the term of this Agreement, the payments by the Company or Employer under
Section 5(b) hereof shall be correspondingly reduced. Notwithstanding anything
in this Agreement to the contrary, if Employee’s employment is terminated
following a Change in Control of the Company, Employee shall have no duty to
seek other employment nor shall any payments made or to be made to Employee
pursuant to this Agreement following such Change in Control be offset by any
amount earned from other employment.

          (f) Full Satisfaction of Obligations. Payment by Employer or the
Company of the amounts owed to Employee pursuant to this Section 5 shall fully
satisfy all obligations of Employer and the Company to Employee under this
Agreement if the employment of Employee is terminated hereunder prior to the
expiration of the Employment Term, and all obligations of

6

--------------------------------------------------------------------------------

 

Employer and Employer to each other set forth in Sections 1 through 4 of this
Agreement shall terminate and be of no further force or effect. No termination
of employment hereunder, whether by Employer or Employee and whether with or
without Cause or Good Reason, shall terminate the provisions of Sections 6 or 7
or any subsequent sections of this Agreement and each of such sections shall
remain in full force and effect as binding obligations of the parties in
accordance with their express terms or, if no express term is stated, until the
latest to expire of those sections having express terms.

     6. Business Disclosures. Employee acknowledges that in connection with his
prior service as a director of the Company and his prospective employment with
the Company, Employee has had and will have access to and has or will become
familiar with all or substantially all of the Confidential Information of the
Company and its Affiliates. As a material inducement to the Company and Employer
to enter into this Agreement and to pay to Employee the compensation stated
herein, Employee covenants and agrees that Employee will not, at any time during
or following the termination of his employment with the Company, directly or
indirectly divulge or disclose for any purpose whatsoever any Confidential
Information that has been obtained by or disclosed to Employee in connection
with Employee’s prior service as a director of the Company or his employment
with the Company or any of its Affiliates. If Employee is required in or
pursuant to any legal, judicial or administrative proceeding (by oral questions,
interrogatories, requests for information or documents, subpoena, civil
investigative demand or similar process) to disclose any Confidential
Information, Employee shall notify, as promptly as practicable, the Company of
such request or requirement so that the Company, at its expense, may seek an
appropriate protective order or waive compliance with the provisions of this
Agreement, and/or take any other action deemed appropriate by the Company. If,
in the absence of a protective order or the receipt of a waiver hereunder,
Employee is compelled or required by law or the order of any governmental,
regulatory or self-regulatory body to disclose the Confidential Information,
Employee may disclose only that portion of the requested Confidential
Information which he is compelled or required to disclose, and Employee will
exercise his reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded the Confidential Information.

     7. Non-Competition.

          (a) 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, within a 250-mile radius of any then
existing manufacturing facility of the Company and its subsidiaries and
affiliates, 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 (the “Business”).
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.

7

--------------------------------------------------------------------------------

 

          (b) 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, either hire, seek to hire or solicit the employment of any
employee of the Company or its subsidiaries and Affiliates 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.

The foregoing covenants shall remain in effect during the period of employment
of Employee by the Company and Employer and, after such employment terminates
for any reason whatsoever, for a period of three (3) years immediately following
the longer of (i) the termination of such employment or (ii) the period during
which Employee is entitled to receive payments under Section 5 of this
Agreement.

     8. Consideration for Covenants; Reasonableness. Employee acknowledges and
agrees as follows:

          (a) The Confidential Information of the Company and its Affiliates are
unique and were developed or acquired by them through the expenditure of
valuable time and resources; that Employer, the Company and their Affiliates
derive independent economic value from this Confidential Information not being
generally known to the public or to other persons who can obtain economic value
from their disclosure or use; that Employer, the Company and their Affiliates
have taken all prudent and necessary measures to preserve the proprietary and
confidential nature of their Customer Information, and that the covenants set
forth in Sections 6 and 7 are the most reasonable, efficient and practical means
to protect these Trade Secrets.

          (b) The covenants set forth in Sections 6 and 7 are necessary to
protect the goodwill of the Company and its Affiliates during the employment of
Employee hereunder, and to ensure that such goodwill will be preserved and
continued for the benefit of the Company and its Affiliates after his employment
terminates.

          (c) Due to the nature of the Business as heretofore conducted by the
Company and its Affiliates and as contemplated to be continued and conducted by
the Company and its Affiliates, the scope and the duration of the covenants set
forth in Sections 6 and 7 of this Agreement are in all respects reasonable.

          (d) The covenants set forth in Sections 6 and 7 each constitute a
separate agreement independently supported by good and adequate consideration
and that each such agreement shall be severable from the other provisions of
this Agreement and shall survive this Agreement. The existence of any claim or
cause of action of Employee against Employer or the Company, whether predicated
on this Agreement or otherwise, shall not constitute a defense to the
enforcement by Employer and the Company of the covenants and agreements of
Employee set forth in Sections 6 and 7.

8

--------------------------------------------------------------------------------

 

     9. Surrender of Books and Records. Employee shall on the termination of his
employment in any manner immediately surrender to the Company all lists, books,
and records and other documents incident to the business of the Company and its
Affiliates, and all other property belonging to any of them, it being understood
that all such lists, books, records and other documents are the property of the
Company and its Affiliates.

     10. Waiver of Breach. The failure of the Company, Employer or Employee at
any time to require performance by the other of any provision hereof shall in no
way affect any of their rights thereafter to enforce the same, nor shall the
waiver by the Company, Employer or Employee of any breach of any provision
hereof be taken or held to be a waiver of any succeeding breach of any provision
or as a waiver of the provision itself.

     11. Remedies. In the event of Employee’s breach, or threatened breach, of
any term or provision contained in Section 6 or 7 of this Agreement, Employee
agrees that the Company and its Affiliates shall suffer irreparable harm not
compensable by damages or other legal remedies, and that accordingly the Company
and/or Employer shall be entitled to both temporary and permanent injunctive
relief without the necessity of independent proof by it as to the inadequacy of
legal remedies or the nature or extent of the irreparable harm suffered by it.
The right of the Company and/or Employer to such relief shall not be construed
to prevent it from pursuing, either consecutively or concurrently, any and all
other legal or equitable remedies available to it for such breach or threatened
breach, specifically including, without limitation, the recovery of monetary
damages.

     12. Severability. It is the desire and intent of the parties that the
provisions of Sections 6 and 7 be enforced to the fullest extent permissible
under the laws and public policies of each jurisdiction in which enforcement is
sought. If any provision of Sections 6 or 7 relating to the time period, scope
of activities or geographic area of restrictions is declared by a court of
competent jurisdiction to exceed the maximum permissible time period, scope of
activities or geographic area, the same shall be reduced to the maximum which
such court deems enforceable. If any provision of Sections 6 and 7 other than
those described in the preceding sentence are adjudicated to be invalid or
unenforceable, the invalid or unenforceable provisions shall be deemed amended
(with respect only to the jurisdiction in which such adjudication is made) in
such manner as to render them enforceable and to effectuate as nearly as
possible the intentions and agreement of the parties. Furthermore, if any other
provision contained in this Agreement should be held illegal, invalid or
unenforceable in whole or in part by a court of competent jurisdiction, then it
is the intent of the parties hereto that the balance of this Agreement be
enforced to the fullest extent permitted by applicable law and, in lieu of such
illegal, invalid or unenforceable provision, there shall be added automatically
as part of this Agreement, a provision as similar in its terms to such invalid
provision as may be possible and be legal, valid, and enforceable.

     13. Attorneys’ Fees. In the event of any suit or judicial proceeding (other
than an arbitration proceeding) between the parties hereto with respect to this
Agreement, the prevailing party shall, in addition to such other relief as the
court may award, be entitled to reasonable attorneys’ fees and costs, all as
actually incurred and including, without limitation, attorneys’ fees and costs
incurred in appellate proceedings; provided, however, that following a Change in
Control

9

--------------------------------------------------------------------------------

 

of the Company, only Employee will be entitled to recover the attorneys’ fees
and costs described in this Section.

     14. Survival. Notwithstanding anything to the contrary contained herein,
the provisions of Sections 5 et. seq. hereof shall survive the termination of
this Agreement.

     15. Notice. All notices hereunder shall be in writing and shall be
delivered personally, sent by facsimile transmission or sent by certified,
registered or overnight mail, postage prepaid. Such notices shall be deemed to
have been duly given upon receipt, if personally delivered, upon telephonic
