may be terminated by the Company or the Executive at any time upon or after such event. Upon termination of the Consulting Term, neither party shall have any further obligations hereunder with respect to the consulting engagement, except that:

(a) the Company shall be obligated to pay to Executive any compensation earned or expenses to be reimbursed under Sections 9 and 10 below,

(b) if such termination occurs after a Change of Control, the aggregate amount of monthly installments to be paid through December 31, 2005 shall be paid to Executive in a lump sum, and

8. Consulting Services. During the Consulting Term, Executive shall make himself available for consultation services to assist management and the Board of Directors of the Company at such times and in such manner as Executive shall reasonably agree; provided, however, that Executive shall not be obligated to make himself available for more than five (5) days during any calendar month during the Consulting Term.

9. Consulting Fees. As compensation for his consulting services and related agreements hereunder, Executive shall be paid at an annual rate of $150,000, payable in monthly installments of $12,500.00 during the Consulting Term.

10. Assistance/Expenses. The Company agrees to provide or to cause to be provided to Executive such assistance as Company determines to be required for Executive to discharge any responsibilities assigned pursuant to Section 8. The Company shall pay or reimburse Executive for the reasonable and appropriate out-of-pocket expenses incurred by him in connection with the performance of services as an employee prior to retirement, the performance of services as a director of the Company or any of its subsidiaries, and the performance of his consulting services during the Consulting Term, in each instance in accordance with the Company’s expense reimbursement policies. Executive must provide proper documentation to Company for all expenses before the Company’s obligations to reimburse arise. During the period that Executive remains a director of the Company or any of its subsidiaries or is providing consulting services to the Company, the Company shall also provide Executive with office and support services in Lake Forest, Illinois substantially the same as currently provided to him in that locale.

11. Confidential Information. Executive understands and acknowledges: (a) his obligations to the Company under Section 12 of the Employment Agreement, and (b) that such obligations, as well as his obligations pursuant to applicable policies of the Company provided to him and under applicable law relating to confidential information, shall continue to apply to and obligate Executive during and after the Term, as if set forth herein in full.

12. Non-Competition. Executive understands and acknowledges and agrees (a) his obligations under Section 13 of the Employment Agreement and (b) that such obligations shall continue to apply and restrict Executive during and after the Term and for the period through

A-4

April 30, 2006. Executive acknowledges and agrees that the continuation of such restrictions to April 30, 2006 represents an extension beyond the date otherwise applicable under the Employment Agreement and that the benefits and payments provided hereunder represent adequate consideration for such extension.

13. Remedies. Executive acknowledges that the restraints and agreements above provided are fair and reasonable, that enforcement of the obligations described in Sections 11 and 12 will not cause him undue hardship and that said provisions are reasonably necessary and commensurate with the need to protect the Company and its legitimate and proprietary business interests and property from irreparable harm. Executive acknowledges and agrees that (a) a material breach of any of the obligations described in Sections 11 or 12 above, will result in irreparable harm to the business of the Company, (b) a remedy at law in the form of monetary damages for any material breach by him of any of the obligations described in Sections 11 and 12 is inadequate, (c) in addition to any remedy at law or equity for such material breach, the Company shall be entitled to institute and maintain appropriate proceedings in equity, including a suit for injunction to enforce the specific performance by Executive of the obligations hereunder and to enjoin Executive from engaging in any activity in violation hereof and (d) the obligations on his part described in Sections 11 and 12, shall be construed as agreements independent of any other provisions in this Agreement, and the existence of any claim, setoff or cause of action by Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense or bar to the specific enforcement by the Company of said covenants.

14. Independent Contractor. The parties to this Agreement intend that during the Consulting Term, the Executive will perform under this Agreement as an independent contractor, and not as an employee of the Company or its affiliates; and that neither this Agreement nor the Continuing Participant Agreement shall be construed to continue Executive’s employment by the Company beyond the date of his retirement. Consequently, during the Consulting Term:

(a) the Executive shall be solely responsible for the payment of all taxes in connection with the fee payable under Section 9, and the Company shall not withhold taxes from his remuneration; and

(b) the Executive shall not accrue or receive any benefits under any employee benefit plan maintained by the Company or any of its subsidiaries or affiliates except for such payments and participation described in Sections 3 and 4, attributable to his services hereunder, provided that nothing in this Agreement shall affect any rights to benefits Executive (and Executive’s spouse and dependents) might have under any employee benefit plans of the Company by virtue of his service as an employee and/or his retirement.

15. Indemnification. Executive shall continue to be entitled to indemnification and advancement of expenses to the fullest extent permitted by Delaware law, the Company’s Restated Certificate of Incorporation, the Company’s By-Laws, any prior agreement with the Company or any insurance policy or policies maintained by the Company, with respect to costs, expenses and obligations Executive may pay or incur as a result of any claim made or threatened which is related to the fact that he is or was an officer, director, employee, agent or fiduciary of the Company, or is or was serving in any such capacity for any corporation, employee benefit

A-5

plan or other entity at the request of the Company, or Executive providing services hereunder. In addition, to the extent the Company maintains an insurance policy or policies providing director and officer liability insurance, Executive will continue to be covered by such policy or policies, in accordance with their terms, to the maximum extent of the coverage available for any Company director or officer. The rights described in this Section 15 shall be in addition to any rights Executive may have to indemnification and advancement of expenses under Delaware or any other law, the Company’s governing documents, or any other agreement or insurance policy.

16. Entire Understanding. This Agreement constitutes the entire understanding between the parties relating to certain matters concerning Executive’s retirement, Executive’s employment during the period from December 31, 2002 through the Retirement Date, and consulting services hereunder. To the extent that any provision hereof relating to the terms and conditions of Executive’s employment with the Company are inconsistent with the provisions of the Employment Agreement, then the provisions of this Agreement shall constitute an amendment to the Employment Agreement, it being agreed that nothing herein or any event arising after December 31, 2002, shall give rise to any severance or separation payments under Section 8(b) or (c) of the Employment Agreement. Any amendment of this Agreement shall be effective only to the extent that it is in writing, executed by the Company and Executive.

17. Binding Effect. This Agreement shall be binding upon and inure to the benefit of Executive’s executors, administrators, legal representatives, heirs and legatees and on the Company and its affiliates and their respective successors and assigns.

In no event, however, will an Option be exercisable after the Expiration Date thereof.

Upon the termination of the Continuation Period pursuant to clause (a), (b) or (c) above, your Options will continue to be exercisable by you (or in the event of your death, by your beneficiary or your estate’s executor or administrator) to the same degree that your Options were exercisable at the termination of the Continuation Period (including any acceleration of vesting which may occur in the event of death), until the first of the following occur:

(i)   the expiration of three years after the date of termination of the Continuation Period; or

(ii)   the Expiration Date.

(4) Merger, Consolidation or Change in Control.

(7) Future Grants: Reload Provisions. You are not entitled to receive any additional stock options pursuant to the Plan during the Continuation Period. Accordingly, no reload stock option will be granted upon any exercise of your Options during the Continuation Period.

(8) Employment; Successors.

This Agreement shall be binding upon, and inure to the benefit of, any successor or successors of the Company and to your successors and beneficiaries.
