(g) Change in Control and Technology Agreements. Employee and the Company expressly acknowledge and agree that, effective as of the date hereof, the Change of Control Agreement entered into between the Company and Employee dated June 30, 2001, as amended on November 25, 2002, and the Technology Agreement between the Company and the Employee dated May 13, 1969 shall become null and void and have no further force or effect.

(i) Excise Tax Gross-Up.

(i) In the event that Employee becomes entitled to the payments and benefits provided under Section 3 above and/or any other payments or benefits in connection with a change in control or termination of Employee’s employment with the Company (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change in control or any person affiliated with the Company or such person) (collectively, the “Payments”), and if any of the Payments will be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code, then (A) if the aggregate amount of the Payments is equal to or greater than 330% of the “base amount” as defined in Section 280G(b)(3) of the Code, then the Company shall pay to Employee, at least 30 days prior to the time payment of any such Excise Tax is due, an additional amount (the “Gross-Up Payment”) such that the net amount retained by Employee, after deduction of any Excise Tax and any federal and state and local income tax imposed on the Gross-Up Payment, shall be equal to the Excise Tax imposed on the Payments; and (B) if the aggregate amount of the Payments is less than 330% of the “base amount,” then the aggregate present value of the payments made pursuant to the terms of this Agreement alone without taking into account payments made pursuant to any other agreements between the Company and Employee shall be reduced so that the Payment equals 299.99% of the “base amount” (it being understood that in no event shall the amount of the payment made pursuant to the terms of this Agreement be less than $0).

(ii) For purposes of determining whether any of the Payments will be subject to the Excise Tax and the amount of such Excise Tax, (A) the Payments shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code,

5

and all “excess parachute payments” within the meaning of Section 280G(b)(l) of the Code shall be treated as subject to the Excise Tax, unless, in the opinion of tax counsel selected by the Company’s independent auditors and reasonably acceptable to Employee, the Payments (in whole or in part) do not constitute parachute payments or excess parachute payments or are otherwise not subject to the Excise Tax, (B) the amount of the Payments which shall be treated as subject to the Excise Tax shall be equal to the lesser of (y) the total amount of the Payments or (z) the amount of excess parachute payments within the meaning of Section 280G(b)(l) (after applying clause (A) above), and (C) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Company’s independent auditors in accordance with the principles of Section 280G(d)(3) and (4) of the Code.

(iii) For purposes of determining the amount of the Gross-Up Payment, Employee shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in the calendar year in which the Gross-Up Payment is to be made and state and local income taxes at the highest marginal rate of taxation in the state and locality of Employee’s residence on the Termination Date, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes.

(iv) In the event that the Excise Tax is subsequently determined to be less than the amount taken into account hereunder at the time of termination of Employee’s employment, Employee shall repay to the Company at the time that the amount of such reduction in Excise Tax is finally determined, the portion of the Gross-Up Payment attributable to such reduction (plus the portion of the Gross-Up Payment attributable to the Excise Tax and federal and state and local income tax imposed on the Gross-Up Payment being repaid by Employee if such repayment results in a reduction in Excise Tax and/or a federal and state and local income tax deduction) plus interest on the amount of such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the event that the Excise Tax is determined to exceed the amount taken into account hereunder at the time of the termination of Employee’s employment (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross-Up Payment), the Company shall make an additional Gross-Up Payment in respect of such excess (plus any interest payable with respect to such excess) at the time that the amount of such excess is finally determined.

(j) Company Successors. The Company will require either (1) any acquiror of the Company as a whole or (2) any acquiror of the coated metal business unit and/or the laminates and composites business unit which directly or indirectly becomes the employer of Employee (in each case through merger, consolidation, asset purchase, stock purchase or otherwise) (a “Successor”) to expressly assume 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 such succession had taken place. Failure of the Company to obtain such assumption and agreement shall be a breach of this Agreement and shall entitle Employee to compensation from the Company in the same amount and on the same terms as Employee would be entitled to hereunder if Employee terminated Employee’s employment by the Company for Good Reason, except that for purposes of implementing the foregoing, the date on which any such succession becomes

6

effective shall be deemed the Termination Date. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor which assumes and agrees to perform this Agreement by operation of law, or otherwise.

5. Confidential Information and Ownership of Property.

(a) Confidential Information. Employee agrees to use all Confidential Information solely in connection with the performance of services for or on behalf of the Company. Employee shall not, during the term of this Agreement, or at any time after the termination of this Agreement, in any manner, either directly or indirectly, (i) disseminate, disclose, use or communicate any Confidential Information to any person or entity, regardless of whether such Confidential Information is considered to be confidential by third parties, or (ii) otherwise directly or indirectly misuse any Confidential Information; provided, however, that (y) none of the provisions of this Section shall apply to disclosures made for valid business purposes of the Company or (z) that Employee shall not be obligated to treat as confidential any Confidential Information that (I) was publicly known at the time of disclosure to Employee; (II) becomes publicly known or available thereafter other than by means in violation of this Agreement or any other duty owed to the Company or any of its Affiliates by any person or entity; or (III) is lawfully disclosed to Employee by a third party. Notwithstanding the foregoing, Employee shall be permitted to disclose Confidential Information to the extent required to enforce Employee’s rights hereunder in any litigation arising under, or pertaining to, this Agreement provided that Employee shall give prior written notice to the Company of any such disclosure so that the Company may have an opportunity to protect the confidentiality of such Confidential Information in such litigation.

(b) Ownership of Property. Employee agrees that all works of authorship developed, authored, written, created or contributed to during the term of his employment for the benefit of the Company, whether solely or jointly with others, shall be considered works-made-for-hire. Employee agrees that such works shall be the sole and exclusive property of the Company (or its appropriate Affiliate) and that all right, title and interest therein or thereto, including all intellectual property rights existing or obtained in connection therewith, shall likewise be the sole and exclusive property of the Company (or its appropriate Affiliate). Employee agrees further that, in the event that any work is not considered to be work-made-for-hire by operation of law, Employee will immediately, and without further compensation, assign all of Employee’s right, title and interest therein to the Company (or its designated Affiliate), its successors and assigns. At the request and expense of the Company, Employee agrees to perform in a timely manner such further acts as may be necessary or desirable to transfer, defend or perfect the Company’s ownership of such work and all rights incident thereto.

6. Covenant Not to Compete. Employee covenants and agrees that Employee shall not anywhere in North America (including, without limitation, the United States, Canada and Mexico), during the term of Employee’s employment by the Company or any Affiliate thereof and for the Non-Compete Period, directly or indirectly own an interest in, operate, join, control, advise, work for, consult to, have a financial interest which provides any control of, or participate in any corporation, partnership, proprietorship, firm, association, person, or other entity producing, designing, providing, soliciting orders for, selling, distributing, consulting to, or marketing or re-marketing products, goods, equipment, or services competitive with or in

7

substantially the same line of business as the Company or any Affiliate thereof, or any part thereof, as of the commencement of the Non-Compete Period. This covenant does not prohibit the mere ownership of less than three percent (3%) of the outstanding stock of any publicly-traded corporation as long as Employee is not otherwise in violation of this Agreement.

7. Covenant Against Solicitation of Employees. During the term of Employee’s employment by the Company and for the Non-Compete Period, Employee shall not employ employees or agents or former employees or agents of the Company or its Affiliates or, directly or indirectly, solicit or otherwise encourage the employment of employees or agents or former employees or agents of the Company or its Affiliates; provided, however, that this restriction shall not apply to former employees or agents (y) who, as of the date of termination of Employee’s employment by the Company, have not worked for any of the Company or its Affiliates during the twelve preceding months or (z) whose employment by the Company or any Affiliate thereof was terminated by the Company.

8. Remedies.

(a) Employee Acknowledgements. Employee acknowledges (i) that the covenants contained in Sections 5, 6 and 7, including, without limitation, the time and geographic limits (collectively, the “Restrictive Covenants”), are reasonable and appropriate and that Employee will not any claim to the contrary in any action brought by the Company or its Affiliates to enforce any of such provisions and (ii) that should Employee violate any of the Restrictive Covenants, it will be difficult to determine the resulting damages to the Company and its Affiliates and, in addition to any other remedies the Company and its Affiliates may have, (A) the Company and its Affiliates shall be entitled to temporary injunctive relief without being required to post a bond and permanent injunctive relief without the necessity of proving actual damage; and (B) the Company shall have the right to offset against its obligation to make any payments to Employee under this Agreement or otherwise to the extent of any money damages incurred or suffered by the Company and its Affiliates. The Company may elect to seek one or more of these remedies at its sole discretion on a case by case basis. Failure to seek any or all remedies in one case shall not restrict the Company from seeking any remedies in another situation. Such action by the Company shall not constitute a waiver of any of its rights.

(b) Intent. It is the parties’ intent that each of the Restrictive Covenants be read and interpreted with every reasonable inference given to its enforceability. However, it is also the parties’ intent that if any term, provision or condition of the Restrictive Covenants is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the provisions thereof shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Finally, it is also the parties’ intent that if a court should determine any of the Restrictive Covenants are unenforceable because of over-breadth, then the court shall modify said covenant so as to make it reasonable and enforceable under the prevailing circumstances.

(c) Tolling. In the event of any breach by Employee of any Restrictive Covenant, the running of the period of restriction shall be automatically tolled and suspended for the duration of such breach, and shall automatically recommence when such breach is remedied in order that the Company shall receive the full benefit of Employee’s compliance with each of the Restrictive Covenants.

8

(d) Independent Enforcement. Employee agrees that the Restrictive Covenants shall be enforced independently of any other obligations between the Company, on the one hand, and Employee, on the other, and that the existence of any other claim or defense shall not affect the enforceability of the Restrictive Covenants or the remedies provided herein. The Restrictive Covenants shall be in addition to and shall not replace any other restrictive covenant agreement that Employee may currently have (or hereafter enter into) with the Company or any of its Affiliates.
