Exhibit 10.1

AGREEMENT

THIS AGREEMENT (the “Agreement”) made effective as of October 24, 2006 (the “Effective Date”), by and between NCI Building Systems, Inc., a Delaware corporation with its principal office in the State of Texas (the “Company”) and Albert R. Ginn, Jr. (the “Employee”).

WITNESSETH:

WHEREAS, the Employee has served as an employee and executive officer of the Company, including its Chief Executive Officer, since 1998; and

WHEREAS, the Employee desires to retire as an executive officer of the Company and all of its subsidiaries and related entities, including the positions of Chairman of the Board and Chief Executive Officer; and

WHEREAS, the Company desires that the Employee remain, and the Employee has agreed to remain, as an employee of the Company in his current position until the earlier to occur of certain events or a date specified herein, and thereafter the Employee has agreed to remain an employee in a consultant capacity; and

WHEREAS, in consideration of the mutual promises contained herein, the parties hereto are willing to enter into this Agreement upon the terms and conditions herein set forth.

NOW, THEREFORE, in consideration of the premises, the terms and provisions set forth herein, the mutual benefits to be gained by the performance thereof and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Resignation from Officer Positions. The Employee agrees to remain employed in his current positions in a full-time capacity through the dates specified herein. Effective as of December 31, 2006, the Employee agrees to resign each of his officer positions with the Company and any of its subsidiaries with the exception of his position as Chairman of the Board of the Company, and the Employee further agrees to resign each of his director positions with any of the Company’s subsidiaries. The Employee shall remain employed in his position of Chairman of the Board of the Company through the Transition Date, and shall resign from such position and as a director of the Company on that date. “Transition Date,” as used herein, shall mean December 31, 2007.

2. Employment and Separation from Employment. Following the Transition Date, the Company hereby agrees to continue the Employee in its employ, and the Employee hereby agrees to remain in the employ of the Company, for the Advisory Period (as defined below). During the first two (2) years of the Advisory Period, the Employee agrees to perform the services set forth below up to a maximum time commitment of 240 hours per year and, during years 3-10 of the Advisory Period, the Employee agrees to

perform the services set forth below up to a maximum time commitment of 120 hours per year; provided, however, that the Employee shall not be obligated to perform such services at times or places when they would interfere with the Employee’s pursuit of other personal and business interests not inconsistent with the terms of this Agreement:

a. Provide such services as are reasonably necessary to assist the Company in a transition of the Employee’s responsibilities as an officer of the Company and its subsidiaries to any successor to such responsibilities,

b. Respond to the best of his knowledge and belief to any questions posed by or on behalf of the Company regarding any litigation in which the Company or any affiliate is then or may become involved, and

c. Perform such other consulting services for the Company and its affiliates as shall be reasonably requested by the Chief Executive Officer of the Company and that are not materially different from Employee’s prior duties and responsibilities as an officer of the Company.

d. From time to time through the Termination Date (as defined below), the Company may utilize the Employee as a pilot for one or more of its corporate aircraft on an as needed basis; provided, however, that the Employee remains qualified to serve in such capacity. The Company shall be responsible for providing adequate insurance coverage (to the extent that such coverage is available on a commercially practicable basis) on all such flights and, further, the Company shall be responsible for all costs necessary for the Employee to maintain his flight certifications during such period.

The “Advisory Period” shall be the period from the Transition Date through December 31, 2017 (the “Termination Date”). Unless earlier terminated pursuant to Section 4, the Employee’s employment with the Company shall terminate as of the Termination Date.

3. Salary and Benefits. Except as otherwise set forth in this Section 3 or in Section 4, the Employee shall be entitled to the consideration set forth below during the period beginning on the Effective Date and ending on the Termination Date. In addition, provided that the Employee does not violate the provisions of Section 5 below, it is specifically understood and agreed that the Employee shall be entitled to the benefit provided to him under the terms of the Supplemental Benefit Agreement between the Company and the Employee, dated December 13, 2002 (the “Supplemental Benefit Agreement”).

a. Salary Prior to the Transition Date. From the Effective Date through the Transition Date, the Employee shall continue to receive the Employee’s base salary as in effect as of the Effective Date, payable in accordance with the Company’s regular payroll practices.

b. Salary during the Advisory Period. From January 1, 2008 through December 31, 2009, the Employee shall receive a base salary of $200,000 per annum, payable in accordance with the Company’s regular payroll practices. From January 1, 2010 through the Termination Date, the Employee shall receive a base salary of

$100,000 per annum, payable in accordance with the Company’s regular payroll practices. Notwithstanding the foregoing, the Employee’s right to the compensation specified in this Section 3(b) is conditioned upon his not revoking the release provisions of Section 6 in accordance with the provisions thereof.

c. Bonus. The Employee shall be eligible for a bonus for the Company’s 2007 fiscal year at the executive bonus level in effect for Employee on the Effective Date. The Employee shall not be eligible for a bonus thereafter unless approved by the senior management or Board of Directors of the Company, in their discretion.

d. Restricted Stock. The Employee shall be eligible for awards of restricted stock of the Company (“Restricted Stock Awards”) pursuant to the Company’s 2003 Long-Term Stock Incentive Plan, as amended from time to time (the “2003 Plan”) through the Transition Date at the executive level in effect for Employee on the Effective Date. The Restricted Stock Awards granted after December 31, 2006, if any, shall vest ratably over four (4) years subject to the Employee’s continued service to the Company and shall have terms consistent with the terms generally applicable to other executive officers of the Company; provided, however, that such Restricted Stock Awards shall not provide for full vesting solely due to attainment of retirement age. Notwithstanding the foregoing, all Restricted Stock Awards granted to the Employee prior to December 31, 2006 will fully vest as of January 1, 2008, or the Employee’s earlier Disability (as defined herein) or death. Notwithstanding the foregoing, nothing in this Agreement is intended to nor shall it be construed as a modification of that certain Special Long-Term Restricted Stock Agreement between the Company and A.R. Ginn, dated May 28, 2004 and as amended effective October 24, 2005, except as specifically set forth herein, which shall fully vest according to its terms on January 1, 2008 provided that the Employee remains in Continuous Service (as defined in such agreement) with the Company until such date.

e. Options. For purposes of determining the exercisability and term of stock options granted to the Employee prior to the Transition Date, the Employee shall be deemed to have retired effective on the Transition Date.

f. Welfare Benefits. During the Advisory Period, the Employee and his spouse shall be eligible to participate in the group health and medical benefit programs that are generally made available to active employees of the Company at the applicable active employee premium rate. In addition, the Employee shall be eligible to participate in long-term healthcare insurance coverage, if any, which is made available to employees of the Company, subject to the terms and conditions of such coverage and to payment of applicable premiums.

g. Other Benefits. From the Effective Date through the Transition Date, the Employee shall continue to participate in the Company’s employee benefit plans and programs and perquisites on the same terms and conditions applicable to executive management employees on the Effective Date. Effective as of the Transition Date, the Employee shall be deemed to have terminated for purposes of the Company’s Deferred Compensation Plan and for purposes of the Supplemental Benefit Agreement, and the Employee shall begin to receive his benefit under the Supplemental Benefit Agreement

starting on January 15, 2008, provided that the Employee is considered to have a “termination from employment” on the Transition Date as determined pursuant to Section 409A (defined in Section 9 hereof). Except as specifically set forth above in subsection (f) above, from and after January 1, 2008, the Employee shall not be eligible to participate in any employee benefit plan or program, including without limitation 401(k), retirement, profit-sharing, bonus, Deferred Compensation Plan, severance or any other plan or program made available to employees of the Company and its affiliates. The Employee shall be eligible for payment of vacation and sick day accruals through the Transition Date, payable as soon as practicable after that date.

h. Reimbursement of Expenses. The Company will reimburse the Employee for reasonable travel and other business expenses incurred by him in the fulfillment of his duties hereunder upon presentation by the Employee of an itemized account of such expenditures, in accordance with Company practices and policies.

i. Use of Office and Administrative Support Staff. The Employee may continue the use and occupancy of his current office at the Company’s headquarters in Houston, Texas, until July 1, 2007. From July 1, 2007 through the Transition Date, the Company may provide to the Employee an office as the Company in its discretion determines appropriate. In addition, the Company shall make available to the Employee an administrative assistant through the Transition Date.

4. Termination of Employment. Notwithstanding the provisions of Sections 1 and 2, the Employee’s employment with the Company may be terminated in any of the following ways:

a. Termination without Cause, Disability. If the Employee’s employment with the Company is terminated by the Company without Cause (as defined in Section 4(b) below) or if the Employee or Employer terminates employment due to Disability (“Disability,” as used herein, shall have the meaning ascribed to it in the 2003 Plan), the Employee shall continue to receive the salary and benefits provided under Sections 3(a)-(i), to the extent applicable and as provided therein, as if he had remained employed through the Termination Date. In the event of the Employee’s death after termination under this Section 4(a), the Employee’s surviving spouse, if any, shall be entitled to receive continued salary payments as provided in Sections 3(a) and (b), and to continued health and medical coverage as provided under Section 3(f), through the period ending on the earlier of (i) the Termination Date, or (ii) the date of her death.

b. Termination for Cause and Voluntary Termination. If the Employee’s employment with the Company is terminated by the Company for Cause (as defined below) or if the Employee voluntarily terminates employment for any reason other than Disability, the Company’s obligation to make the payments or provide the benefits listed under Section 3 of this Agreement shall immediately terminate as of the date of the Employee’s termination except to the extent that such payment(s) or benefit(s) are earned as of such date. For purposes of this Agreement, “Cause” shall mean: (i) the Employee’s willful and continued failure to substantially perform his duties and other obligations under this Agreement and such failure continues for

a period of thirty (30) days after written notice by the Company of the existence of such failure; provided, however, that only one such notice by the Company need be sent and, if such failure re-occurs thereafter, no further notice and opportunity to cure such failure shall be required; (ii) the willful engaging by the Employee in gross misconduct materially and demonstrably injurious to the Company, as determined by the Company; or (iii) the Employee’s conviction for committing an act of fraud, embezzlement, theft or other act constituting a felony (which shall not include any act or offense involving the operation of a motor vehicle); provided, however, that the Board of Directors of the Company or the then current Chairman of the Board must first provide to Employee written notice clearly and fully describing the particular acts or omissions which the Board or the then current Chairman of the Board reasonably believes in good faith constitutes Cause under this subsection (b) and an opportunity, within thirty (30) days following the receipt of such notice, to meet in person with the Board of Directors or the then current Chairman of the Board to explain the alleged acts or omissions relied upon by the Board of Directors and, to the extent practicable, to cure such acts or omissions. For purposes of this Agreement, any termination of the Employee’s employment for Cause shall be effective only upon delivery to the Employee of a certified copy of a resolution of the Board of Directors of the Company, adopted by the affirmative vote of a majority of the entire membership of the Board of Directors following a meeting at which the Employee was given an opportunity to be heard on at least five (5) business days’ advance notice, finding that the Employee was guilty of the conduct constituting Cause, and specifying the particulars thereof. Further, for the purposes of this Agreement, no act or failure to act on the Employee’s part shall be considered willful unless done, or omitted from being done, by the Employee not in good faith and without reasonable belief that his action or omission was in the best interest of the Company.

c. Death. The Employee’s employment under this Agreement shall terminate automatically upon his death, and the Employee’s surviving spouse, if any, shall be entitled to receive continued salary payments as provided in Sections 3(a) and (b), and to continued health and medical coverage as provided under Section 3(f), through the period ending on the earlier of (i) the Termination Date, or (ii) the date of her death.

5. Restrictive Covenants. As a material inducement to the Company to enter into this Agreement, the Employee agrees to the restrictive covenants set forth below:

a. Non-Competition. During the Advisory Period and for the period ending five (5) years following the Termination Date, the 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, or lend money or equipment to or otherwise support, 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, sectional or roll-up doors,

or other metal components of a building structure), coated or painted steel or metal coils, coil coating or coil 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 prior to the Termination Date. Ownership by the Employee of equity securities of the Company, or of equity securities in other public or privately-owned companies that compete with the Company constituting less than 1% of the voting securities in such companies, shall be deemed not to be a breach of this covenant. The Employee agrees and stipulates that in any action or claim brought by him or in any action or claim brought against him involving the provisions of this Section 5, the Employee hereby waives any claim or defense that the above non-competition covenants are unenforceable, void or voidable, for any reason, including, but not limited to, fraud, misrepresentation, illegality, unenforceable restraint of trade, failure of consideration, illusory contract, mistake, or any other substantive legal defense.

b. Non-Solicitation. During the Advisory Period and for the period ending five (5) years following the Termination Date, the 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 (i) hire, seek to hire or solicit the employment or service of any employee, agent or consultant of the Company or its Subsidiaries and affiliates in a commercial capacity; (ii) in any manner attempt to influence or induce any employee, agent or consultant of the Company or its Subsidiaries and affiliates to leave the employment or service of the Company or its Subsidiaries and affiliates; (iii) use or disclose to any person, partnership, association, corporation or other entity any information concerning the names and addresses of any employees, agents or consultants of the Company or its Subsidiaries and affiliates unless such use or disclosure is of a personal nature, is requested by the Company or is required by due process of law; or (iv) call upon, solicit, divert or attempt to call upon, solicit or divert the business of any customer, vendor or acquisition prospect of the Company or any of its Subsidiaries or affiliates with whom the Company dealt, directly or indirectly, during his engagement with the Company or its Subsidiaries or affiliates. The Employee shall not be prohibited from hiring or soliciting the employment or service of an agent or consultant of the Company for purposes which do not violate Section 5(a) of this Agreement. The Employee agrees and stipulates that in any action or claim brought by him or in any action or claim brought against him involving the provisions of this Section 5, the Employee hereby waives any claim or defense that the above non-solicitation covenants are unenforceable, void or voidable, for any reason, including, but not limited to, fraud, misrepresentation, illegality, unenforceable restraint of trade, failure of consideration, illusory contract, mistake, or any other substantive legal defense.

c. Confidential Information. For purposes of the covenants made in this Section 5, the Company promises to provide the Employee (as is necessary for the Employee’s position) with various trade secrets and proprietary and confidential information consisting of, but not limited to, business and/or strategic plans, budgets, fiscal plans, processes, computer programs, compilations of information, records, sales procedures, customer requirements, pricing techniques, customer lists, methods of doing business and other confidential information (collectively referred to

as the “Trade Secrets”), which are owned by the Company and regularly used in the operation of its business, but in connection with which the Company takes precautions to prevent dissemination to persons other than certain directors, officers and employees. As used herein, “Trade Secrets” does not include any information that at the time of disclosure or thereafter is generally available to or known by the public (other than as a result of a disclosure by the Employee or any of his representatives in violation of the terms of this Agreement). The Employee acknowledges and agrees that the Trade Secrets (i) are secret and not known in the industry or to the public; (ii) are entrusted to him after being informed of their confidential and secret status by the Company and because of the fiduciary position occupied by him with the Company; (iii) have been developed by the Company for, and on behalf of, the Company through substantial expenditures of time, effort and money and are used in its business; (iv) give the Company an advantage over competitors who do not know or use the Trade Secrets; (v) are of such value and nature as to make it reasonable and necessary to protect and preserve the confidentiality and secrecy of the Trade Secrets; and (vi) the Trade Secrets are valuable, special and unique assets of the Company, the disclosure of which could cause substantial injury and loss of profits and goodwill to the Company. The Employee shall not use in any way or disclose any of the Trade Secrets, directly or indirectly, during the Advisory Period, or at any time thereafter, except as required in the course of his employment with the Company. The Employee agrees that in any action or claim brought by him or in any action or claim brought against him involving the provisions of this Section 5, the Employee hereby waives any claim or defense that the above covenants are unenforceable, void or voidable, for any reason, including, but not limited to, fraud, misrepresentation, illegality, unenforceable restraint of trade, failure of consideration, illusory contract, mistake, or any other substantive legal defense. All files, records, documents, information, data and similar items relating to the business of the Company, whether prepared by the Employee or otherwise coming into his possession, shall remain the exclusive property of the Company and shall not be removed from the premises of the Company under any circumstances without the prior written consent of the Board of Directors of the Company (except in the ordinary course of business during the Employee’s employment with the Company), and in any event shall be promptly delivered to the Company upon termination of the Employee’s employment for any reason. The Employee agrees that, upon his receipt of any subpoena, process or other request to produce or divulge, directly or indirectly, any Trade Secrets to any entity, agency, tribunal or person, he shall timely notify and promptly deliver a copy of the subpoena, process and stipulates or other request to the Chairman of the Board and Chief Executive Officer of the Company. For this purpose, the Employee irrevocably nominates and appoints the Company (including any attorney retained by the Company), as his true and lawful attorney-in-fact, to act in his name, place and stead to perform any act that he might perform to defend and protect against any disclosure of any Trade Secrets.

d. Non-Disparagement. The Employee agrees to refrain from any criticisms or disparaging comments about the Company or any affiliates (including any current officer, director or employee of the Company), and the Employee agrees not to take any action, or assist any person in taking any other action, that is adverse to the

interests of the Company or any affiliate or inconsistent with fostering the goodwill of the Company and its affiliates; provided, however, that nothing in this Agreement shall apply to or restrict in any way the communication of information by the Company or the Employee to any state or federal law enforcement agency or to the Board of Directors or senior management of the Company or require notice to the Company thereof, and the Employee will not be in breach of the covenant contained above solely by reason of testimony which is compelled by process of law.

e. Standstill. The Employee agrees that during the Advisory Period and for the period ending five (5) years after the Advisory Period, neither he nor anyone acting on his behalf will, without the prior written consent of the Company’s Board of Directors, directly or indirectly: (i) except for a written offer or proposal submitted confidentially to the Company, acquire, offer, propose or seek to acquire, or agree to acquire, by purchase or otherwise, any securities or assets of the Company, or direct or indirect rights to acquire securities or assets of the Company exceeding one percent (1%) of the then outstanding securities or assets of the Company; (ii) make, or in any way participate, in any “solicitation” of “proxies” or consents to vote (as such terms are used in the rules of the Securities and Exchange Commission), or otherwise act, alone or in concert with others, to seek to control or influence the management, Board of Directors or policies of the Company; (iii) make any public announcement with respect to, or offers of, (with or without conditions) any Extraordinary Transaction involving the Company or any of its securities or assets, or otherwise take any actions, other than submitting to the Company a confidential written offer or proposal, which might force the Company to make a public announcement regarding such matters; (iv) form, join or in any way participate in a “group” as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, in connection with any of the foregoing; or (v) request the Company to amend or waive any provision of this paragraph; provided, however, (A) this subparagraph (e) shall not apply to the acquisition by the Employee of any securities of the Company directly from the Company, whether pursuant to the exercise of options or vesting of restricted stock or otherwise; (B) this subparagraph (e) shall terminate and the restrictions contained herein shall cease to apply to the Employee upon the earliest to occur of any of the following with respect to the Company: (x) the Company enters into a definitive agreement with respect to an Extraordinary Transaction, (y) any person makes an unsolicited public offer for an Extraordinary Transaction for the Company, or (z) a Change of Control of the Company; (C) “Extraordinary Transaction” means any acquisition of a significant amount of securities or assets of the Company or any of its affiliates, including in connection with any extraordinary transaction, such as a merger, reorganization, recapitalization, tender or exchange offer, or asset disposition involving the Company or any of its affiliates that, if consummated, such acquisition, transaction, merger, reorganization, recapitalization, tender or exchange offer, or asset disposition would result in a Change in Control of the Company; and (D) “Change in Control” shall have the meaning set forth in the 2003 Plan.

f. Enforcement.

1. Generally. The Employee hereby agrees that a breach of any of the provisions of this Section 5 would cause irreparable injury to the Company and its affiliates, for which they would have no adequate remedy at law. If the Employee breaches any of the covenants set forth in this Section 5, then without regard for any provision to the contrary, the Company shall have the right to immediately

discontinue all payments and benefits under Section 3 hereof to the Employee and his spouse, except to the extent that such payment(s) or benefit(s) are earned as of such date, and to immediately seek injunctive relief from a court having jurisdiction for any actual breach of this Section 5. Any such injunctive relief shall be in addition to any other remedies to which the Company may be entitled at law, in equity or otherwise. The Employee hereby agrees that upon receipt of notice of the Company’s intent to seek injunctive relief, the Employee will not sell, transfer, pledge, exchange, hypothecate, or otherwise encumber or dispose of any shares of stock granted to the Employee under the Restricted Stock Awards awarded after December 31, 2006, or any right or interest therein, pending the final resolution of such injunctive relief proceeding. In addition, the Employee shall, within ten (10) business days after it is ultimately determined that he has committed such a breach hereof, either (i) redeliver to the Company the Vested Shares (as defined herein), if still owned by the Employee, or (ii) reimburse the Company an amount in cash or immediately available funds equal to the aggregate net sales price received by the Employee or, if any of said shares were transferred by the Employee for less than fair market value, then an amount equal to the fair market value of the transferred shares as of the trading date immediately prior to payment to the Company, determined by using the last sales price of the Company’s common stock (as reported by the New York Stock Exchange) on such trading date. If it is determined that the Employee has not committed a breach thereof, the Company shall resume the payments and benefits under Section 3 and pay to Employee and his spouse all payments and benefits under Section 3 that had been suspended pending such determination. Any equity award granted prior to December 31, 2006 shall be governed by the terms of the award agreement for such award except as otherwise provided with respect to vesting as set forth in Section 3(d) of this Agreement.

The parties hereto intend all provisions of subsections (a), (b), (c), (d), (e) and (f) of this Section 5 to be enforced to the fullest extent permitted by law. Accordingly, should a court of competent jurisdiction determine that the scope of any provision of subsections (a), (b), (c), (d) and (e) of this Section 5 is too broad to be enforced as written, the parties intend that the court may reform the provision to such narrower scope as it determines to be reasonable and enforceable, and, in the event the court reforms Section 5(a) hereof, the Company may elect to either accept enforcement of the provision as so modified or require the return of Vested Shares (as defined herein) or cash as set forth in Section 5(f)(2). In addition, however, the Employee agrees and stipulates that the non-competition agreements, non-solicitation agreements, non-disclosure, non-disparagement and standstill agreements (set forth above in subsections (a), (b), (c), (d), and (e) of Section 5, respectively) each constitute separate agreements independently supported by good and adequate consideration and shall survive this Agreement. The existence of any claim or cause of action of the Employee against the Company, except for a breach of this Agreement by the Company or its subsidiaries, shall not constitute a defense to the enforcement by the Company of the covenants and agreements of the Employee contained in the non-competition, non-solicitation, non-disclosure, non-disparagement and standstill agreements (set forth above in subsections (a), (b), (c), (d), and (e) of Section 5, respectively). The Employee agrees and stipulates that in

any action or claim brought by him or in any action or claim brought against him involving the provisions of this Section 5, the Employee hereby expressly waives any claim or defense that the above covenants are unenforceable, void or voidable, for any reason, including, but not limited to, fraud, misrepresentation, illegality, unenforceable restraint of trade, failure of consideration, illusory contract, mistake, or any other substantive legal defense.

2. Non-Competition. If in connection with the challenge by the Employee of any provision of Section 5(a), any court of competent jurisdiction determines that the non-competition agreement in Section 5(a) hereof is void or unenforceable, or if the court modifies Section 5(a) and the Company declines to accept the modification, then (i) the Employee shall forfeit all stock granted to the Employee under all Restricted Stock Awards dated after December 31, 2006 which have not vested and agrees to return to the Company (A) any such vested shares of stock granted to the Employee under such Restricted Stock Awards (the “Vested Shares”) still owned by the Employee, and (B) an amount in cash or immediately available funds equal to the aggregate net sales price received by the Employee for such shares that are no longer held by the Employee or, if any of such shares were transferred by the Employee for less than fair market value, then an amount equal to the fair market value of the transferred shares as of the trading date immediately prior to payment to the Company, determined by using the last sales price of the Company’s common stock (as reported by the New York Stock Exchange) on such trading date, and (ii) any equity award granted prior to December 31, 2006 shall be governed by the terms of the award agreement for such award.

6. Release of Claims by the Employee. In exchange for the consideration offered to the Employee under this Agreement, the Employee, on his behalf and on behalf of his heirs, devisees, legatees, executors, administrators, personal and legal representatives, assigns and successors in interest, hereby IRREVOCABLY, UNCONDITIONALLY AND GENERALLY RELEASES, ACQUITS, AND FOREVER DISCHARGES, to the fullest extent permitted by law, the Company, its subsidiaries and each of the their directors, officers, employees, representatives, stockholders, predecessors, successors, assigns, agents, attorneys, divisions, subsidiaries and affiliates (and agents, directors, officers, employees, representatives and attorneys of such stockholders, predecessors, successors, assigns, divisions, subsidiaries and affiliates), and all persons acting by, through, under or in concert with any of them (collectively, the “Releasees” and each a “Releasee”), or any of them, from any and all charges, complaints, claims, damages, actions, causes of action, suits, rights, demands, grievances, costs, losses, debts, and expenses (including attorneys’ fees and costs incurred), of any nature whatsoever, known or unknown, that the Employee now has, owns, or holds, or claims to have, own, or hold, or which the Employee at any time heretofore had, owned, or held, or claimed to have, own, or hold from the beginning of time to the date that the Employee signs this Agreement, including, but not limited to, those claims arising out of or relating to (i) any agreement, commitment, contract, mortgage, deed of trust, bond, indenture, lease, license, note, franchise, certificate, option, warrant, right or other instrument, document, obligation or arrangement, whether written or oral, or any other relationship, involving the Employee and/or any Releasee, (ii) breach of any express or implied contract, breach of implied covenant of good faith and fair dealing, misrepresentation, interference with

contractual or business relations, personal injury, slander, libel, assault, battery, negligence, negligent or intentional infliction of emotional distress or mental suffering, false imprisonment, wrongful termination, wrongful demotion, wrongful failure to promote, wrongful deprivation of a career opportunity, discrimination (including disparate treatment and disparate impact), hostile work environment, sexual harassment, retaliation, any request to submit to a drug or polygraph test, and/or whistleblowing, whether said claim(s) are brought pursuant to laws of the United States or any other jurisdiction applicable to the Employee’s actions on behalf of the Company or any of its subsidiaries or affiliates, and (iii) any other matter; provided, however, that nothing contained herein shall operate to release any obligations of the Company or its successors or assigns arising under this Agreement. Notwithstanding anything in this Agreement to the contrary, it is the express intention of the Employee and the Company that this Agreement shall not act as a release or waiver of (1) any rights of defense or indemnification which would be otherwise afforded to the Employee under the Certificate of Incorporation, By-Laws or similar governing documents of the Company or its subsidiaries or under that certain Indemnification Agreement by and between the Company and the Employee, dated October 13, 2000; (2) any rights of defense or indemnification which would be otherwise afforded to the Employee under any director or officer liability or other insurance policy maintained by the Company or its subsidiaries; (3) any rights of the Employee to benefits accrued under any Company employee benefit plans, including but not limited to the NCI 401(k) Profit Sharing Plan, the NCI Building Systems, Inc. Deferred Compensation Plan (Plan Year 2006), applicable health, medical and welfare benefit programs, and the like; (4) any rights under this Agreement; and (5) such other rights or claims as may arise after the date of this Agreement. The Employee acknowledges that he has had at least 21 calendar days after this Agreement was presented to him to consider whether to sign this Agreement. The Employee has until the date that is seven (7) days after the date this Agreement is executed by him to revoke the release set forth in this Section 6, after which this Section 6 shall become irrevocable, provided, however, that if the Employee so revokes this Section 6, the Company shall have no obligation to provide to the Employee the payments specified in Section 3(b) hereof. Effective as of January 1, 2008, Employee shall execute that certain release agreement attached hereto as Exhibit “A.”

7. Stock Trading and Company Policies. During the period beginning on the Effective Date and ending two business days after the Company first issues an earnings release following the date as of which the Employee is no longer serving as a director or executive officer of the Company, the Employee agrees to comply with all of the Company’s policies with respect to trading in the Company’s securities to the same extent as such policies are applicable to executive officers of the Company including, without limitation, “blackout” periods restricting or prohibiting trading in the Company’s securities, whether regularly scheduled or imposed under special circumstances, and any “lockup” requested by any underwriter with respect to an offering of the Company’s securities, and during the Advisory Period the Employee agrees to comply with the foregoing if he is in possession of material non-public information relating to the Company.

8. Non-Alienation. The Employee shall not have any right to pledge, hypothecate, anticipate, or in any way create a lien upon any amounts due or payable under this Agreement, and no payments or benefits due hereunder shall be assignable in anticipation of payment either by voluntary or involuntary acts or by operation of law. So

long as the Employee lives, no person, other than the parties hereto, shall have any rights under or interest in this Agreement or the subject matter hereof. Upon the death of the Employee, his surviving spouse, if any, shall have the right to enforce the provisions hereof.

The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no succession had taken place and (a) if such successor does not expressly assume and agree to perform this Agreement, or if such assumption does not occur by operation of law, and (b) if such transaction satisfies the requirements to avoid the imposition of an excise tax under the provisions of Section 409A of the Internal Revenue Code and related regulations and Treasury pronouncements (“Section 409A”) or such payment restrictions are otherwise inapplicable, then the Company shall be obligated to make a cash payment to the Employee, immediately following such succession (or, if later, the first date at which payment can be made without incurring an excise tax under Section 409A), equal to the aggregate value of (i) the salary otherwise payable pursuant to Sections 3(a) and (b) for the remainder of the term of this Agreement, without reduction for early payout, and (ii) a sum equivalent to the number of months remaining under the term of the Agreement, multiplied by the most recent applicable rate charged to terminated employees for continuation of comparable health insurance coverage (COBRA coverage), with no offset for the Employee’s portion of the premium.
