equal to 10% of the amount of the distribution. Such distribution shall be made in a method determined pursuant to Section 3.4.

Notwithstanding any other provisions of the Plan, a Participant may modify his election as to the form or time of distribution of his Post-2004 Benefit applicable to his Supplemental Retirement Benefit if (i) such election does not take effect until at least 12 months after the date on which the election is made, (ii) the first payment with respect to which such election is made is deferred for a period of not less than five years from the date on which such payment would otherwise have been made, and (iii) any election related to a payment to be made at a specified date is made at least 12 months prior to the date of the first scheduled payment.

4.8 Investment of Supplemental Contributions.

(a) Investments. Amounts credited hereunder to the Supplemental Accounts of a Participant shall be treated as if they were actually invested in various investment funds that are made available by the Committee from time to time and as are designated by each Participant pursuant to investment directions given to the Committee. Such Accounts shall be credited with earnings, gains and losses of the applicable investment funds on the last day of each calendar quarter or on such other date selected

by the Committee. Investment directions shall be made by a Participant in specified multiples of 10%.

(b) Investment Changes. Each Participant shall have the right to direct the Committee to modify his investment directions made pursuant to paragraph (a) above with respect to amounts credited to his Supplemental Accounts after the date such modification direction becomes effective, in specified multiples of 10%. Each Participant shall also have the right to direct the Committee to change the investment directions made pursuant to paragraph (a) above with respect to amounts credited to his Accounts on the date such direction to change becomes effective, in specified multiples of 10%.

(c) Effective Date of Investment Direction. Any investment direction, or modification or change of an investment direction, made pursuant to paragraph (a) or (b) above, shall be effective as soon as practicable after (and in any event not later than the first day of the month that occurs at least 30 days after) the date the applicable direction is given to the Committee. A modification or change of an investment direction made pursuant to paragraph (b) may, if required by an administrative rule promulgated by the Committee, be made only once in each calendar quarter.

In the event that the sponsor of the investment funds permits more frequent fund transfers than permitted above, or does not require written direction to authorize fund transactions, the Committee may waive or modify the requirements set forth in the preceding provisions of this Section as it deems appropriate.

(d) Investment Funds. Any investments made by the Company or by the Trustee of Trust Agreement No. 2 referred to in paragraph (f) below to conform to directions made by a Participant pursuant to this Section shall be in investment funds maintained in the name of the Company, or in the name of such Trustee, and no Participant shall at any time have any interest in the assets of any such investment fund.

(a) Separation From Service Prior to Death. Following a Participant’s separation from service with the Company and all Affiliated Companies for any reason other than death, a Participant shall receive a distribution of all amounts credited to his Supplemental Accounts, including gains and losses credited in accordance with Section 4.8.

(b) Distribution Due to Death. If a Participant dies before distribution to him of the full amount of his Supplemental Accounts, any remaining amount shall be distributed to his beneficiary designated under the Qualified Profit Sharing Plan. If a Participant has not designated a beneficiary under the Qualified Profit Sharing Plan, or if no designated beneficiary is living on the date of distribution hereunder, amounts distributable pursuant to this paragraph shall be distributed to those persons or entities entitled to receive distributions of the Participant’s accounts under the Qualified Profit Sharing Plan.

(c) Unforeseeable Emergency Distribution. A Participant shall be entitled to request a distribution from his Supplemental Deferral Account, prior to his separation from service with the Company and all Affiliated Companies, in order to satisfy an Unforeseeable Emergency. Such a distribution may also include amounts necessary to pay federal, state or local income taxes or penalties reasonably anticipated to result from a distribution applicable to the Participant’s Post-2004 Benefit. Except with respect to eligibility for such a distribution, the procedures for requesting and receiving such a distribution shall satisfy the requirements set forth in the Qualified Profit Sharing Plan with respect to a hardship distribution from his Qualified Salary Deferral Account. A request for a distribution pursuant to this paragraph shall be made separate and apart from a request for a distribution under the Qualified Profit Sharing Plan, and a request for a hardship distribution under the Qualified Profit Sharing Plan shall not automatically be deemed a request for a distribution hereunder.

(d) Time and Form of Payment of Supplemental Accounts. Payment of the balance of a Participant’s Supplemental Accounts shall be paid or commence to be paid to him either (i) as of the date of his separation from service with the Company and all Affiliated Companies, or (ii) as of the first day of a calendar month and year elected by the Participant (which shall be no later than 15 years after the date of his separation from service). Such distribution shall be paid or commence to be paid to the Participant in either (1) a single lump sum, or (2) installments over a number of years (not to exceed 15) payable in monthly, quarterly or annual installments, as elected by the Participant. Any Participant in the Plan on December 31, 2004 shall make such time and form elections on or before December 31, 2005. If a Participant does not make timely elections with respect to the time or form of payment pursuant to the preceding sentence, such payment shall be made to him as of his separation from service in a lump sum. Notwithstanding the preceding sentence, in the case of an Executive Officer or Key Employee who becomes a Participant on or after January 1, 2005, the aforementioned elections with respect to the time and form of payment shall be made within 30 days after

the individual first becomes eligible to participate and such elections shall be effective with respect to the portion of his Supplemental Accounts related to services to be performed subsequent to the election; provided that any portion of such Accounts related to services performed prior to the election shall be payable to him in a single lump sum as of his date of separation from service; and provided further that such an individual shall not be considered first eligible if, on the date he becomes a Participant, he participates in any other nonqualified account balance plan that is subject to Code Section 409A maintained by the Company or any Affiliated Company.

(e) Notwithstanding any provision in the Plan to the contrary, a Participant may elect a distribution of all or any portion of his Pre-2005 Benefit applicable to the amounts credited to his Supplemental Deferral Account, his Supplemental Company Account, and his Supplemental Profit Sharing Account, including gains and losses credited to the date of distribution in accordance with Section 4.8, at any time if (i) he elects such distribution by written instrument delivered to the Committee at least six months in advance of the date such distribution is received, or (ii) the distribution is subject to a forfeiture penalty equal to 10% of the amount of the distribution. Such distribution shall be made in a method determined pursuant to Section 4.9(d).

(f) Notwithstanding any other provision of this Section 4.9, a Participant may modify his election as to the form or time of distribution of all or any portion of his Post-2004 Benefit applicable to amounts credited to his Supplemental Accounts, and earnings thereon, if (i) such election does not take effect until at least 12 months after the date on which the election is made, (ii) the first payment with respect to which such election is made is deferred for a period of not less than five years from the date on which such payment would otherwise have been made, and (iii) any election related to a payment to be made at a specified date is made at least 12 months prior to the date of the first scheduled payment.

Notwithstanding any other provision of this Section 4.9, a Participant may change an election with respect to the time and form of payment of such portion of his Post-2004 Benefit, without regard to the restrictions imposed under the preceding paragraph on or before December 31, 2006; provided that such election (1) applies only to amounts that would not otherwise be payable in calendar year 2006, and (2) shall not cause an amount to be paid in calendar year 2006 that would not otherwise be payable in such year.

(g) Notwithstanding any provision in the Plan to the contrary, in the event of a potential Change in Control of the Company, as determined solely by the Board in its discretion, the portion of the Pre-2005 Benefit applicable to all amounts credited to each Participant’s Supplemental Salary Account, his Supplemental Company Account, and his Supplemental Profit Sharing Account, including gains and losses credited to the date of distribution in accordance with Section 4.8, shall be distributed to him in a lump sum as soon as practicable following the date of such determination by the Board.

(h) Notwithstanding any provision in the Plan to the contrary, the following provisions shall apply, prior to January 1, 2008, to the amounts credited to such Participant’s Supplemental Accounts on or before March 21, 2006 following the first to occur of: (i) a drop in the overall credit rating of the Company below S&P BB or Moody’s Ba; (ii) a drop in the Company’s market capitalization below $75 million for five consecutive trading days; (iii) a drop in the aggregate of cash and existing available bank lines of the Company below $35 million; and (iv) receipt of a notice of material adverse change under any of the Company’s then existing debt agreements:

(i) During the 30-day period commencing on the date an event described in clause (i), (ii), (iii), or (iv) occurs, the Company, in its sole discretion, may distribute all or any part of such portion of a Participant’s Benefit credited to his Supplemental Accounts on or before March 21, 2006 , including gains and losses credited in accordance with Section 4.8 to the date of distribution, to him in a lump sum as the Company deems appropriate and in the best interest of the Company.

(ii) No distribution due to the occurrence of an event described in clause (i), (ii), (iii), or (iv) shall be made from and after the 30th day following the date of such event.

(iii) Following the expiration of the 30-day period after the date of an event described in clause (i), (ii), (iii), or (iv), a Participant shall continue to accrue benefits pursuant to Article III if he is an Executive Officer, and make deferrals and receive contributions pursuant to Article IV.

(iv) The Company shall be entitled to make separate decisions in accordance with clause (i) with respect to the interests of each Participant hereunder.

(i) In no event may a Participant borrow amounts credited to the Accounts maintained for him pursuant to this Article IV.

ARTICLE VII
AMENDMENT OR TERMINATION

7.1 Amendment or Termination. The Company intends the Plan to be permanent but reserves the right to amend or terminate the Plan when, in the sole opinion of the Company, such amendment or termination is advisable. Any such amendment or termination shall be made pursuant to a resolution of the Board and shall be effective as of the date of such resolution or such later date as the resolution may expressly state.

7.4 Termination of Participation. The Company, in its sole discretion, shall have the right to terminate the participation in the Plan or any portion thereof of any Executive Officer or Key Employee whose initial participation in the Plan was designated by the Compensation Committee, upon recommendation of management.

ARTICLE VIII
GENERAL PROVISIONS

8.1 Specified Employee. Notwithstanding any other provision of the Plan, in no event will distribution of a Participant’s Post-2004 Benefit begin earlier than six months following separation from service, unless due to such Participant’s disability or death, if the Participant was a Specified Employee of the Company or an Affiliated Company, at a time during which the Company’s capital stock or capital stock of an Affiliated Company is publicly traded on an established securities market, in the calendar year of his separation from service.

If a Specified Employee will receive payments hereunder in the form of installments, the first payment made as of the date six months after the date of the Participant’s separation from service with the Company and all Affiliated Companies shall be a lump sum, paid as soon as practicable after the end of such six-month period, that includes all payments that would otherwise have been made during such six-month period. From and after the end of such six-month period, any such installment payments shall be made pursuant to the terms of the applicable installment form of payment.

8.2 Participants’ Rights Unsecured. Except as set forth in Section 8.3, the Plan at all times shall be entirely unfunded and no provision shall at any time be made with respect to segregating any assets of the Company or an Affiliated Company for payment of any benefits hereunder. The right of a Participant or his Surviving Spouse or beneficiary to receive a benefit hereunder shall be an unsecured claim against the general assets of the Company, and neither the Participant nor a Surviving Spouse or beneficiary shall have any rights in or against any specific assets of the Company or any Affiliated Company. All amounts credited to Supplemental Salary Deferral Accounts, Supplemental Company Accounts and Supplemental Profit Sharing Accounts of Participants shall constitute general assets of the Company.

Notwithstanding the provisions of Section 8.2, the Company, promptly after the Plan effective date, shall enter into a trust agreement (“Trust Agreement”) with a bank or trust company (with a combined capital and surplus in excess of $100 million dollars), located in the Continental United States, as trustee, whereby the Company shall agree to

contribute to a trust (“Trust”) initially and annually thereafter, for the purpose of accumulating assets actuarially sufficient to satisfy accrued obligations to Participants and Surviving Spouses under Article III hereof, in the event of a Change in Control of the Company. The Trust Agreement shall obligate the Company to make contributions sufficient to satisfy the obligations to Participants, and Surviving Spouses under Article III hereof; provided, however, that such initial contribution shall be made within ten days after the date the Board, in its discretion, deems a Change in Control of the Company likely to occur. The discretion of the Board shall be binding and conclusive with respect to the likelihood of a Change in Control of the Company to occur. Such Trust Agreement shall be substantially in the form of the model trust agreement set forth in Internal Revenue Service Revenue Procedure 92-64, or any subsequent Internal Revenue Service Revenue Procedure, and shall include provisions required in such model trust agreement that all assets of the Trust shall be subject to the creditors of the Company in the event of insolvency. Notwithstanding the provisions of Section 8.2, the Company, on or as soon as practicable after January 1, 1996, shall enter into a Trust Agreement (“Trust Agreement No. 2”) with a bank or trust company (with a combined capital and surplus in excess of $100,000,000) located in the continental United States as Trustee, whereby the Company shall agree to contribute to a trust (“Trust No. 2”) initially and annually thereafter for the purpose of accumulating assets sufficient to provide for Supplemental Salary Deferral Contributions, Supplemental Company Contributions and Supplemental Profit Sharing Contributions with respect to Participants under Article IV hereof. Trust Agreement No. 2 shall be substantially in the form of the model trust agreement set forth in Internal Revenue Service Procedure 92-64, or any subsequent Internal Revenue Service Procedure, and shall include provisions required in such model trust agreement that all assets of Trust No. 2 shall be subject to the creditors of the Company in the event of insolvency. Trust Agreement No. 2 shall include such provisions as are applicable with respect to the investment and reinvestment of such Contributions pursuant to directions given by Participants to the Company and transmitted by the Company to the Trustee of Trust Agreement No. 2 pursuant to paragraph (f) of Section 4.8.

8.4 General Conditions. Except as otherwise expressly provided herein, all terms and conditions of the Qualified Retirement Plan applicable to a Qualified Retirement Benefit, or a Qualified Surviving Spouse Benefit, shall also be applicable to a Supplemental Retirement Benefit or a Supplemental Surviving Spouse Benefit payable hereunder, and all terms and conditions of the Qualified Profit Sharing Plan applicable to a Qualified Salary Deferral Contribution, a Qualified Company Contribution or a Qualified Profit Sharing Contribution shall also be applicable to a Supplemental Salary Deferral Contribution, Supplemental Company Contribution or Supplemental Profit Sharing Contribution to be made hereunder. Any Qualified Retirement Benefit or Qualified Surviving Spouse Benefit or any other benefit payable under the Qualified Retirement Plan shall be paid solely in accordance with the terms and conditions of the Qualified Retirement Plan, any Qualified Salary Deferral Contribution, Qualified Company Contribution or Qualified Profit Sharing Contribution, or any other contribution to be made under the Qualified Profit Sharing Plan shall be made solely in accordance with the terms and conditions of the Qualified Profit Sharing Plan, and nothing in the Plan shall operate or be construed in any way to modify, amend or affect the terms and provisions of the Qualified Retirement Plan or the Qualified Profit Sharing Plan.

8.5 No Guaranty of Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company, any Affiliated Company, or any other person or entity that the assets of the Company or any Affiliated Company will be sufficient to pay any benefit hereunder. No Participant, Surviving Spouse or beneficiary shall have any right to receive a benefit or a distribution of contributions under the Plan except in accordance with the terms of the Plan.

8.6 No Enlargement of Employee Rights. Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Company or any Affiliated Company.

8.7 Spendthrift Provision. No interest of any person or entity in, or right to receive a distribution under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a distribution be taken, either voluntarily or involuntarily for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance and claims in bankruptcy proceedings.

8.8 Applicable Law. The Plan shall be construed and administered under the laws of the State of Illinois except to the extent preempted by federal law.

8.9 Small Benefits. If the actuarial value of any Supplemental Retirement Benefit or Supplemental Surviving Spouse Benefit is $5,000 or less, the Company may pay the actuarial value of such Benefit to the Participant or Surviving Spouse in a single lump sum in lieu of any further Benefit payments hereunder. Notwithstanding the preceding sentence, in no event may a distribution be made to a Participant pursuant to this section with respect to the portion of a Participant’s Post-2004 Benefit applicable to his Supplemental Retirement Benefit unless (a) payment accompanies the termination of the Participant’s entire interest in his benefits under Article III of the Plan and his interest under all other nonqualified non-account balance plans subject to Code Section 409A maintained by the Company or any Affiliated Company, and (b) the payment is made on or before the later of December 31 of the calendar year in which occurs the Participant’s separation from service with the Company and all Affiliated Companies, or the 15th day of the third month following such separation from service.

8.10 Incapacity of Recipient. If any person entitled to a payment under the Plan is deemed by the Company to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefor shall have been made by a duly appointed guardian or other legal representative of such person, the Company may provide for such payment or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a complete discharge of any liability of the Company and the Plan therefor.

8.11 Corporate Successors. The Plan shall be continued, following a transfer or sale of assets of the Company, or following the merger or consolidation of the Company into or with any other corporation or entity, by the transferee, purchaser or successor entity, unless the Plan

has been terminated by the Company pursuant to the provisions of Article VII prior to the effective date of such transaction.

8.12 Unclaimed Benefit. Each Participant, Surviving Spouse or beneficiary shall keep the Company informed of his current address. The Company shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Company within three years after the date on which payment of the Participant’s benefits under the Plan may first be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed, or within three years after the actual death of a Participant, the Company is unable to locate any Surviving Spouse or beneficiary of the Participant, then the Company shall have no further obligation to pay any benefit hereunder to such Participant, Surviving Spouse or beneficiary or any other person and such benefit shall be irrevocably forfeited.

8.13 Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, none of the Company, any Affiliated Company, any member of the Committee, nor any individual acting as an employee or agent of the Company, any Affiliated Company or the Committee, shall be liable to any Participant, former Participant, Surviving Spouse or any other beneficiary or other person for any claim, loss, liability or expense incurred by such Participant, Surviving Spouse or other beneficiary or other person in connection with the Plan.

8.14 Tax Savings. Not withstanding anything to the contrary contained in the Plan, (a) if the Internal Revenue Service prevails in a claim by it that amounts credited to a Participant’s Accounts, and/or earnings thereon, constitute taxable income to the Participant or his beneficiary for any taxable year of his prior to the taxable year in which such credits and/or earnings are distributed to him or (b) legal counsel satisfactory to the Company and the applicable Participant or his beneficiary renders an opinion that the Internal Revenue Service would likely prevail in such a claim, (i) the balance of such Participant’s Accounts that are part of his Pre-2005 Benefit, to the extent constituting taxable income, and (ii) the balance of such Participants Accounts that are part of his Post-2004 Benefit, to the extent constituting taxable income pursuant to Code Section 409A and guidance and regulations thereunder, shall be immediately distributed to the Participant or his beneficiary. For purposes of this paragraph, the Internal Revenue Service shall be deemed to have prevailed in a claim if such claim is upheld by. a court of final jurisdiction, or if the Company, or a Participant or beneficiary, based upon an opinion of legal counsel satisfactory to the Company and the Participant or his beneficiary, fails to appeal a decision of the Internal Revenue Service, or a court of applicable jurisdiction, with respect to such claim, to an appropriate Internal Revenue Service appeals authority or to a court of higher jurisdiction, within the appropriate time period.
