CERTAIN COVENANTS

If the Stockholder is a Management Stockholder, the Stockholder, individually and as to himself or herself only, covenants, for the benefit of the Company and its Subsidiaries:

Section 3.1 Access. The Stockholder acknowledges that (a) he or she has had and will continue to have access to significant confidential and valuable information which can be used unfairly and to the harm of the Company by present or potential competitors in the windows, doors, siding, fencing, railing and decking industry and (b) is agreeing to the covenants set forth in this Article III in order to induce the Company to proceed with the Reorganization Merger or in order to induce the Company to offer the Stockholder the opportunity to make an investment in the Company, as the case may be, which is of substantial benefit to the Stockholder. The covenants set forth in this Article III may only be enforced by the Company or its Subsidiaries.

Section 3.2 During Employment. The Stockholder agrees that, during the period of his or her continued employment or consultancy by the Company or its Affiliates, he or she will not render services to or give advice to, affiliate with (as employer, partner, consultant or otherwise), or invest or acquire any interest in, in whole or in part, any other person or organization, which is engaged or about to become engaged in the Business, in the case of the Stockholder who has corporate level responsibility relating to all such business segments, or developing, manufacturing, marketing or selling, in whole or in part, any of the products sold by each applicable business segment, in the case of the Stockholder who has responsibility relating to one or more but not all of the business segments included in the Business (as the case may be, a “Conflicting Organization”). The Stockholder shall not, however, be prohibited from investing in securities of any company that is listed on a national securities exchange or traded on NASDAQ, provided that he or she does not hereafter own, or have the right to acquire, more than 1% of the outstanding voting securities of such a Conflicting Organization.

Section 3.3 Post Employment. The Stockholder further agrees that, until the expiration of a period of one year after the cessation or termination of his or her employment or consultancy with the Company or any Subsidiary of the Company for any reason, whether voluntary or involuntary or with or without “cause” or Good Reason, he or she (a) will not render services or give advice to, or affiliate with (as employee, partner, consultant or otherwise) or invest or acquire any interest in, any Conflicting Organization and (b) shall not, directly or indirectly, hire or solicit any person, or encourage any other person to hire or solicit any person, who has been employed by the Company or any Subsidiary within one year prior to the date of such hiring or solicitation or encourage any such person to leave such employment. The Stockholder shall not, however, be prohibited from investing in securities of any company that is listed on a national securities exchange or traded on NASDAQ, provided that he or she does not hereafter own, or have the right to acquire, more than 1% of the outstanding voting securities of such company. Notwithstanding the foregoing, (i) if the business of the Conflicting Organization has separate and distinct divisions, The Stockholder may, following termination of such employment, render services to or give advice to, or affiliate with, a division that would not itself constitute a Conflicting Organization if, prior thereto, the Company received written assurances satisfactory to the Company from such Conflicting Organization and the Stockholder that the Stockholder will not directly or indirectly render services or give advice or information to any division of such Conflicting Organization which would itself constitute a Conflicting Organization, and (ii) to the extent the Stockholder is entitled to installment severance payments under any severance agreement, plan or policy of the Company or any Subsidiary, as applicable, upon his termination of employment without “cause,” due to “good reason,” due to a “material adverse change,” or upon “disability,” as each and any of those terms, or terms of similar import, may be used in such severance agreement, plan or policy, then the time period referred to in the first sentence of this Section 3.3 shall not exceed the time period during which the Company or any Subsidiary of the Company is obligated to make such installment severance payments to the Stockholder.

Section 3.4 Blue Pencil If any court determines that any of the covenants set forth in Section 3.2 or 3.3, or any part thereof, is unenforceable because of the duration or geographic scope of such provision, such court shall have the power to reduce the duration or scope of such provision, as the case may be, and, in its reduced form, such provision shall then be enforceable.
