The Executive’s employment with the Company shall continue to be governed by the Executive’s existing or future employment agreements with the Company, if any, or, in the absence of any employment agreement, shall continue to be at the will of the Board of Directors or, if the Executive is not an officer of the Company at the time of the termination of the Executive’s employment with the Company, the will of the Chief Executive Officer of the Company, except that if (i) a Change in Control of the Company shall have occurred before the expiration of the term of this Agreement, and (ii) the Executive’s employment with the Company is terminated (whether by the Executive or the Company or automatically as provided in Section 3) after the occurrence of that Change in Control of the Company, then the Executive shall be entitled to receive certain benefits as provided in this Agreement.

(c) the consummation of (xx) a reorganization, merger, consolidation or sale of the Company, or (yy) a disposition of all or substantially all of the assets of the Company (a “Business Combination”), in each case, unless, following such Business Combination, (i) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, direct or indirectly, more than 80 percent of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (ii) no Covered Person (excluding any employee benefit plan (or related trust) of the Company or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20 percent or more of, respectively, the then outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such corporation, except to the extent that such ownership existed prior to the Business Combination, and (iii) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination, were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board of Directors, providing for such Business Combination; or

Section 3. Term of This Agreement. The term of this Agreement shall begin on the Effective Date and, unless automatically extended pursuant to the second sentence of this Section 3, shall expire on the first to occur of:

(i) the Executive’s death or the Executive’s Disability, which events shall also be deemed automatically to terminate Executive’s employment by the Company;

(ii) the termination by the Executive or the Company of the Executive’s employment by the Company; or

(iii) the end of the last day (the “Expiration Date”) of:

(1) the three-year period beginning on the Effective Date (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3) if no Change in Control of the Company shall have occurred during that three-year period (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3); or

(2) if one or more Changes in Control of the Company shall have occurred during the three-year period beginning on the Effective Date (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3), the three-year period beginning on the date on which the last Change in Control of the Company occurred.

If (i) the term of this Agreement shall not have expired as a result of the occurrence of one of the events described in clause (i) or (ii) of the immediately preceding sentence, and (ii) the Company shall not have given notice to the Executive at least ninety (90) days before the Expiration Date that the term of this Agreement will expire on the Expiration Date, then the term of this Agreement shall be automatically extended for successive one-year periods (the first such period to begin on the day immediately following the Expiration Date) unless the Company shall have given notice to the Executive at least ninety (90) days before the end of any one-year period for which the term of this Agreement shall have been automatically extended that such term will expire at the end of that one-year period. The expiration of the term of this Agreement shall not terminate this Agreement itself or affect the right of the Executive or the Executive’s legal representatives to enforce the payment of any amount or other benefit to which the Executive was entitled before the expiration of the term of this Agreement or to which the Executive became entitled as a result of the event (including the termination, whether by the Executive or the Company or automatically as provided in this Section 3, of the Executive’s employment by the Company) that caused the term of this Agreement to expire.

Section 4. Event of Termination for Cause. An “Event of Termination for Cause”shall have occurred if, after a Change in Control of the Company, the Executive shall have committed:

(iii) intentional wrongful damage to property of the Company;

(iv) intentional wrongful disclosure of secret processes or confidential information of the Company; or

Notwithstanding the foregoing, the Executive shall not be deemed to have been terminated as a result of an “Event of Termination for Cause” hereunder unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the Board of Directors then in office at a meeting of the Board of Directors called and held for such purpose (after reasonable notice to the Executive and an opportunity for the Executive, together with his counsel, to be heard before the Board of Directors), finding that, in the good faith opinion of the Board of Directors, the Executive had committed an act set forth above in this Section 4 and specifying the particulars thereof in detail.

T HIS A GREEMENT between Quanex Building Products Corporation, a Delaware corporation (the “Company”), and Martin Ketelaar (the “Executive”) is effective as of the Effective Date (as defined herein).

W I T N E S S E T H:

W HEREAS , the Company considers it to be in the best interests of its stockholders to encourage the continued employment of certain key employees of the Company notwithstanding the possibility, threat or occurrence of a Change in Control of the Company (as that phrase is defined in Section 2); and

W HEREAS , the Executive is a key employee of the Company; and

W HEREAS , the Company believes that the possibility of the occurrence of a Change in Control of the Company may result in the termination by the Executive of the Executive’s employment by the Company or in the distraction of the Executive from the performance of his duties to the Company, in either case to the detriment of the Company and its stockholders; and

W HEREAS , the Company previously recognized that the Executive could suffer adverse financial and professional consequences if a Change in Control of the Company were to occur and entered into this Agreement to protect the Executive if a Change in Control of the Company occurs; and

The Executive’s employment with the Company shall continue to be governed by the Executive’s existing or future employment agreements with the Company, if any, or, in the absence of any employment agreement, shall continue to be at the will of the Board of Directors or, if the Executive is not an officer of the Company at the time of the termination of the Executive’s employment with the Company, the will of the Chief Executive Officer of the Company, except that if (i) a Change in Control of the Company shall have occurred before the expiration of the term of this Agreement, and (ii) the Executive’s employment with the Company is terminated (whether by the Executive or the Company or automatically as provided in Section 3) after the occurrence of that Change in Control of the Company, then the Executive shall be entitled to receive certain benefits as provided in this Agreement.

(b) Notwithstanding anything contained in this Agreement to the contrary, if following the commencement of any discussion with a third person that ultimately results in a Change in Control of the Company, (i) the Executive’s employment with the Company is terminated, (ii) the Executive is removed from any material duties or position with the Company, (iii) the Executive’s Base Salary is reduced, or (iv) the Executive’s annual bonus is reduced to an amount less than the Benchmark Bonus, then for all purposes of this Agreement, such Change in Control of the Company shall be deemed to have occurred on the date immediately prior to the date of such termination, removal, or reduction.

(c) Nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any plan, program, policy or practice of or provided by the Company or any of its Affiliates and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Company or any of its Affiliates. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, program, policy or practice of or provided by, or any contract or agreement with, the Company or any of its Affiliates at or subsequent to the date of termination of the Executive’s employment with the Company shall be payable or otherwise provided in accordance with such plan, program, policy or practice or contract or agreement except as explicitly modified by this Agreement.

(c) the consummation of (xx) a reorganization, merger, consolidation or sale of the Company, or (yy) a disposition of all or substantially all of the assets of the Company (a “Business Combination”), in each case, unless, following such Business Combination, (i) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, direct or indirectly, more than 80 percent of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (ii) no Covered Person (excluding any employee benefit plan (or related trust) of the Company or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20 percent or more of, respectively, the then outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such corporation, except to the extent that such ownership existed prior to the Business Combination, and (iii) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination, were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board of Directors, providing for such Business Combination; or

Section 3 . Term of This Agreement . The term of this Agreement shall begin on the Effective Date and, unless automatically extended pursuant to the second sentence of this Section 3, shall expire on the first to occur of:

(ii) the termination by the Executive or the Company of the Executive’s employment by the Company; or

(iii) the end of the last day (the “Expiration Date”) of:

(1) the three-year period beginning on the Effective Date (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3) if no Change in Control of the Company shall have occurred during that three-year period (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3); or

(2) if one or more Changes in Control of the Company shall have occurred during the three-year period beginning on the Effective Date (or any period for which the term of this Agreement shall have been automatically extended pursuant to the second sentence of this Section 3), the three-year period beginning on the date on which the last Change in Control of the Company occurred.

If (i) the term of this Agreement shall not have expired as a result of the occurrence of one of the events described in clause (i) or (ii) of the immediately preceding sentence, and (ii) the Company shall not have given notice to the Executive at least ninety (90) days before the Expiration Date that the term of this Agreement will expire on the Expiration Date, then the term of this Agreement shall be automatically extended for successive one-year periods (the first such period to begin on the day immediately following the Expiration Date) unless the Company shall have given notice to the Executive at least ninety (90) days before the end of any one-year period for which the term of this Agreement shall have been automatically extended that such term will expire at the end of that one-year period. The expiration of the term of this Agreement shall not terminate this Agreement itself or affect the right of the Executive or the Executive’s legal representatives to enforce the payment of any amount or other benefit to which the Executive was entitled before the expiration of the term of this Agreement or to which the Executive became entitled as a result of the event (including the termination, whether by the Executive or the Company or automatically as provided in this Section 3, of the Executive’s employment by the Company) that caused the term of this Agreement to expire.
