(e) Fringe Benefits. During the term of his employment hereunder, the Executive shall be entitled to participate in or receive benefits under any life insurance, health, retirement and accident plans or arrangements made generally available by the Company to its executives and key management employees, subject to and on a basis consistent with the terms, conditions and overall administration of such plans and arrangements. Notwithstanding anything else in this Agreement to the contrary the Executive shall receive the following benefits, which shall be in lieu of any similar benefits which may be received by the other executives of the Company:

3

election, pay to the Executive an amount of cash sufficient for the purchase and maintenance of term life insurance as described in subdivision (a) above. In addition, to the extent that, but for subdivision (b) of the immediately preceding sentence, any portion of the cost of the insurance described in subdivision (a) of said sentence would be excluded from the Executive’s gross income for federal and/or state income tax purposes, the Company will pay to the Executive an additional amount of cash compensation sufficient to place the Executive in the same after-tax economic position as that in which the Executive would be if subdivision (b) were not a part of said sentence.

(ii) Disability. The Company will purchase disability insurance (with the proceeds thereof payable to the Executive) covering the Executive if the Executive is permanently disabled as a result of any illness, injury or accident, physical or mental, and is unable to perform satisfactorily his duties hereunder on a full time basis for six consecutive months, that will provide for coverage in an amount mutually satisfactory to the parties hereto.

5. Unauthorized Disclosure; Inventions.

(a) Unauthorized Disclosure. The Executive shall not, without the written consent of the Board of Directors or a person duly authorized thereby, disclose to any person, other than an employee or professional adviser of the Company or other person to whom disclosure is in the reasonable judgment of the Executive necessary or appropriate in connection with the performance by the Executive of his duties as an executive officer of the Company, any information obtained by him while in the employ of the Company the disclosure of which he knows or, in the exercise of reasonable care, should know may be damaging to the Company; provided, however, that such information shall not include any information known generally to the public (other than as a result of unauthorized disclosure by the Executive); and provided, further, that the Executive’s duties under this subsection (a) shall not extend to any disclosures that may be required by law in connection with any judicial or administrative proceeding or inquiry, as may be required by federal and/or state securities law, or as may otherwise be required by the rules of any exchange or association which lists the Company’s securities.

(b) Proprietary Rights. Any and all inventions, discoveries, developments, methods, processes, compositions, works, concepts and ideas (whether or not patentable or copyrightable) conceived, made, developed, created or reduced to practice by the Executive (whether at the request or suggestion of the Company or otherwise, whether alone or in conjunction with others, and whether during regular hours of work or otherwise) during the period of his employment by the Company and for three months thereafter, which may be directly or indirectly useful in, or relate to, the business of or products manufactured or sold by the Company or any of its subsidiaries of affiliates or any business or products contemplated by the Company while the Executive is employed by the Company, shall be promptly and fully disclosed by the Executive to an appropriate executive officer of the Company and shall be the Company’s exclusive property as against the Executive, and the Executive shall promptly deliver to an appropriate executive officer of the Company all papers, drawings, models, data and other material relating to any of the foregoing proprietary rights, conceived, made, developed or created by him as aforesaid.

The Executive shall, upon the Company’s request and without any payment therefor (except for Company Policy Awards), execute any documents necessary or advisable in the opinion of the Company’s counsel to assign his right, title and interest in the foregoing proprietary rights and to direct issuance of patents or copyrights to the Company with respect to such proprietary rights as are to be the Company’s exclusive property as against the Executive under this subsection (b) or to vest in the Company title to such proprietary rights as against the Executive, the expense of securing any such patent or copyright, however, to be borne by the Company.

6. Non-Competition.

The Executive agrees that for a period of twelve (12) months following the Date of Termination, unless the Date of Termination is the Expiration Date, he will not directly or indirectly own, manage, operate, control or participate in the ownership, management, operation or control of, or be connected as an officer, employee, partner, director or otherwise with, or have any financial interest in, or aid or assist anyone else in the conduct of, or solicit any employees of the Company on behalf of, any entity or business which competes directly with any business conducted by the Company or by any group, division or subsidiary of the Company, in any area where such business is being conducted or is proposed to be conducted at the Date of Termination; provided, however, that this provision shall not apply if Executive or the Company terminates his employment on the Expiration Date. It is understood and agreed that, for the purposes of the foregoing provisions of this Section 6, (i) no business shall be deemed to be a business conducted by the Company or any group, division or subsidiary of the Company, unless not less than five percent (5%) of the Company’s consolidated gross sales or operating revenues is derived from, or not less than five percent (5%) of the Company’s consolidated assets are devoted to, such business; and (ii) no business conducted by any entity by which the Executive is employed or in which he is interested or with which he is connected or associated shall be deemed competitive with any business conducted by the Company unless it is one from which five percent (5%) or more of its consolidated gross sales or operating revenues is derived, or to which five percent (5%) or more of its consolidated assets are devoted; provided, however, that if the actual gross sales or operating revenues or assets of such entity derived from or devoted to such business is equal to or in excess of 10% of the most nearly comparable figure for the Company, such business of such entity shall be deemed to be competitive with a business of the Company. Furthermore, ownership of not to exceed five percent (5%) of the voting stock of any publicly held corporation shall not constitute a violation of this

6

Section 6, and ownership of a partial equity interest in Nichols Foot Form also shall not constitute a violation of this Section 6.

7. Termination.

If appropriate, the Board of Directors shall give the Executive a reasonable period of time in which to cure any deficiencies under this Section 7(d). For the purposes of this Agreement, the Company shall have “Cause” to terminate the Executive’s employment hereunder upon the Executive’s (A) material failure, refusal or gross neglect to perform and discharge his duties and responsibilities hereunder, or willful action that is materially inconsistent with the terms hereof, or material breach of his fiduciary duties as an officer or member of the Board of Directors of the Company or any subsidiary or affiliate, or (B) gross and willful misconduct that is materially injurious to the Company, or (C) conviction of a felony involving the personal dishonesty of the Executive (unless such conviction is reversed in any final appeal thereof).
