GRANT OF OPTION. The Compensation Committee of the Board of Directors of Quanex Building Products Corporation, a Delaware corporation (the “Company”), pursuant to the Quanex Building Products Corporation 2008 Omnibus Incentive Plan (the “Plan”), hereby grants to you, the above-named Grantee, effective as of the Date of Grant set forth above, a nonqualified stock option to purchase the total number of shares set forth above of the Company’s common stock, $0.01 par value per share, at the exercise price set forth above for each share subject to this option, subject to adjustment as provided in the Plan. The option is exercisable in installments in accordance with the Vesting Schedule set forth above with the exercise price payable at the time of exercise. To the extent not exercised, installments shall be cumulative and may be exercised in whole or in part until the option terminates. The option may not be exercised after the Expiration Date, or the applicable date following your termination of employment specified in this Stock Option Agreement (this “Agreement”).

TERMINATION OF EMPLOYMENT. The following provisions will apply in the event your employment with the Company and all Affiliates of the Company (collectively, the “Company Group”) terminates before the Expiration Date set forth in the Agreement:

2.1 Termination Generally. If your employment with the Company Group terminates before the Expiration Date for any reason other than one of the reasons described in Section 2.2 or Section 2.3 below, all of your rights in the option shall terminate and become null and void on the earlier of the Expiration Date or 90 days after the date your employment with the Company Group terminates. Except as specified in Section 2.2 or Section 2.3 below, in the event your employment with the Company Group terminates, the option shall not continue to vest after such termination of employment.

2.2 Retirement or Disability. If your employment with the Company Group terminates due to your Retirement or Disability, then your option shall continue to vest after such termination of employment until the earlier of the Expiration Date or three (3) years after the date your employment with the Company Group terminates as a result of Retirement or a Disability. For purposes of this Section 2.2, the term “Retirement” means the voluntary termination of your employment relationship with the Company Group on or after the date on which (a) you are age 65 or (b) you are age 55 and have five years of service with the Company Group.

2.3 Death. If your employment with the Company Group terminates due to your death, then your option shall continue to vest after such termination of employment until the earlier of the Expiration Date or three years after the date of your death. After your death, your executors, administrators or any person or persons to whom your option may be transferred by will or by the laws of descent and distribution, shall have the right, at any time prior to the termination of the option, to exercise the option.

CASHLESS EXERCISE. Cashless exercise, in accordance with the terms of the Plan, shall be available to you for the shares subject to the option.

TAX WITHHOLDING. To the extent that the receipt of the option or the Agreement, the vesting of the option or the exercise of the option results in income to you for federal, state or local income, employment or other tax purposes with respect to which the Company Group has a withholding obligation, you shall deliver to the Company at the time of such receipt, vesting or exercise, as the case may be, such amount of money as the Company Group may require to meet its obligation under applicable tax laws or regulations, and, if you fail to do so, the Company Group is authorized to withhold from the shares subject to the option or from any cash or stock remuneration then or thereafter payable to you any tax required to be withheld by reason of such taxable income, sufficient to satisfy the withholding obligation based on the last per share sales price of the common stock of the Company for the trading day immediately preceding the date that the withholding obligation arises, as reported in the New York Stock Exchange Composite Transactions.

NONTRANSFERABILITY. Except as specified in this Agreement, the option and the Agreement are not transferable or assignable by you other than by will or the laws of descent and distribution, and shall be exercisable during your lifetime only by you.

CAPITAL ADJUSTMENTS AND REORGANIZATIONS. The existence of the option shall not affect in any way the right or power of the Company or any company the stock of which is issued pursuant to the Agreement to make or authorize any adjustment, recapitalization, reorganization or other change in its capital structure or its business, engage in any merger or consolidation, issue any debt or equity securities, dissolve or liquidate, or sell, lease, exchange or otherwise dispose of all or any part of its assets or business, or engage in any other corporate act or proceeding.

EMPLOYMENT RELATIONSHIP. For purposes of the Agreement, you shall be considered to be in the employment of the Company Group as long as you have an employment relationship with the Company Group. The Committee shall determine any questions as to whether and when there has been a termination of such employment relationship, and the cause of such termination, under the Plan and the Committee’s determination shall be final and binding on all persons.

NO RIGHTS AS A STOCKHOLDER. You shall not have any rights as a stockholder of the Company with respect to any shares of common stock covered by the option until the date of the issuance of the shares following exercise of the option pursuant to this Agreement and payment for the shares.

NOT AN EMPLOYMENT AGREEMENT. The Agreement is not an employment agreement, and no provision of the Agreement shall be construed or interpreted to create an employment relationship between you and the Company or any of its Affiliates or guarantee the right to remain employed by the Company or any of its Affiliates for any specified term.

SECURITIES ACT LEGEND. If you are an officer or affiliate of the Company under the Securities Act of 1933, you consent to the placing on any certificate for the Shares of an appropriate legend restricting resale or other transfer of the Shares except in accordance with such Act and all applicable rules thereunder.

LIMIT OF LIABILITY. Under no circumstances will the Company Group be liable for any indirect, incidental, consequential or special damages (including lost profits) of any form incurred by any person, whether or not foreseeable and regardless of the form of the act in which such a claim may be brought, with respect to the Plan.

REGISTRATION. The Shares that may be issued under the Plan are registered with the Securities and Exchange Commission under a Registration Statement on Form S-8.

SALE OF SECURITIES. The Shares that may be issued under this Agreement may not be sold or otherwise disposed of in any manner that would constitute a violation of any applicable federal or state securities laws. You also agree that (a) the Company may refuse to cause the transfer of the Shares to be registered on the stock register of the Company if such proposed transfer would in the opinion of counsel satisfactory to the Company constitute a violation of any applicable federal or state securities law and (b) the Company may give related instructions to the transfer agent, if any, to stop registration of the transfer of the Shares.
