As soon as practicable after the end of each Plan Year, the Company shall make an additional Supplemental Company Contribution to the extent necessary so that the Participant’s Supplemental Company Contributions for the Plan Year are not less than the amount that would be credited if the calculation described above were performed as of the end of the Plan Year rather than the end of each pay period.

4.6 Supplemental Profit Sharing Contributions. A Participant who has in effect a Supplemental Base Salary Deferral Agreement or Supplemental Bonus Deferral Agreement to defer at least 1% of Base Salary or Bonus during a Plan Year shall be eligible to receive a Supplemental Profit Sharing Contribution for the fiscal year ending in such Plan Year. The Supplemental Profit Sharing Contribution shall be equal to an amount resulting from (a) — (b):

(a) The Qualified Profit Sharing Contribution that would have been allocated to the Qualified Profit Sharing Account of the Participant for such fiscal year using a Basic Salary Deferral rate equal to the lesser of 5% or the percentage determined by dividing the sum of the Participant’s Supplemental Base Salary Deferral Contributions, Supplemental Bonus Deferral Contributions and Qualified Salary Deferral Contributions by the sum of the Participant’s Salary and Bonus.

(b) The amount of the Qualified Retirement Savings Plan Contribution actually allocated to the Qualified Profit Sharing Account of the Participant for such fiscal year.

A Supplemental Profit Sharing Contribution made for the benefit of a Participant for any fiscal year shall be credited to a Supplemental Profit Sharing Account maintained under the Plan in the name of such Participant at the same time as Qualified Profit Sharing Contributions are made for such Plan Year.

4.7 Supplemental Company Contributions #2.

(a) During Fiscal Year 2006, 33-1/3% of the Supplemental Retirement Benefit of each Executive Officer who was then an active employee of the Company or an Affiliated Company and a Participant was converted to an equivalent single sum, based upon the benefit accrued as of May 31, 2006 and the lump sum settlement rate assumptions applicable during the second calendar quarter of 2006, and otherwise based upon the same assumptions as those then specified in the Qualified Retirement Plan.

This single sum was transferred to a Supplemental Company Account #2 established for the Participant that is held, administered and invested under Article IV of the Plan and subject to the remaining applicable provisions of the Plan, except as otherwise required by Code Section 409A.

(b) During Fiscal Year 2007, 50% of the remaining lump sum value of the Supplemental Retirement Benefit described in (a) above of each Executive Officer who was then an active employee of the Company or an Affiliated Company and a Participant was transferred to the Participant’s Supplemental Company Account #2.

(c) During Fiscal Year 2008, 100% of the remaining lump sum value of the Supplemental Retirement Benefit described in (a) above of each Executive Officer who was then an active employee of the Company or an Affiliated Company and a Participant was transferred to the Participant’s Supplemental Company Account #2.

4.8 Investment of Supplemental Accounts.

(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. The investment funds may include a fund investing in Common Stock of the Company; provided that such investment shall be limited to the portion of the Participant’s Supplemental Accounts attributable to Supplemental Salary Deferral Contributions and Supplemental Bonus Deferral Contributions (including earnings thereon). 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 on or after the date such modification direction 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 the Trust Agreement referred to in Section 8.2 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.

(e) Statement of Accounts. A statement of accounts for each Participant, showing contributions, earnings, gains and losses and current balances of the Accounts provided for under this Article IV shall be provided to each Participant on not less than a quarterly basis.

(f) Trust Agreement. Notwithstanding the preceding provisions of this Section, during the existence of the Trust Agreement referred to in Section 8.2, the Company shall direct the Trustee of the Trust Agreement to invest and reinvest amounts to conform to directions made by a Participant pursuant to the preceding provisions of this Section 4.8. Directions shall be given by the Company to the Trustee of the Trust Agreement as soon as practicable after such directions are given to the Company by the Participant.

4.9 Distributions.

(a) Termination of Employment Prior to Death. Following a Participant’s termination of employment 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. Each Participant shall have a right to designate, by giving a written designation to the Committee, a beneficiary or beneficiaries to receive any amount remaining to be distributed to such Participant in the event that he dies before distribution of the full amount of his Supplemental Accounts. Successive beneficiary designations may be made, and the last designation received by the Committee prior to the death of the Participant shall be effective and shall revoke all prior designations. If a designated beneficiary shall die before the Participant, his interest shall terminate and, unless otherwise provided in the Participant’s designation, such interest shall be paid in equal shares to those beneficiaries, if any, who survive the Participant. If a Participant has not designated a beneficiary, 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 Retirement Savings Plan. Distributions to a beneficiary shall be in the same form and at the same time as elected by the Participant.

(c) Unforeseeable Emergency Distribution. A Participant shall be entitled to request a distribution from his Supplemental Deferral Account, prior to his termination of employment 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 Retirement Savings Plan with respect to a hardship distribution. A request for a distribution pursuant to this paragraph shall be made separate and apart from a request for a distribution under the Qualified Retirement Savings Plan, and a request for a hardship distribution under the Qualified Retirement Savings 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 Deferral Account shall be paid or commence to be paid to him on the first day of a calendar month and year elected by the Participant (which shall be no earlier than the first day of the seventh month following the date of the Participant’s termination of employment and no later than 15 years after the date of his termination of employment). 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. If a Participant does not make timely elections with respect to the time or form of payment pursuant to the preceding sentences, payment of his Supplemental Deferral Account shall be made to him in a lump sum on the first day of the seventh month following his termination of employment. Payment of the balance of a Participant’s Supplemental Accounts other than his Supplemental Deferral Account shall be paid to the Participant on the first day of the seventh month following the date of his termination of employment with the Company and all Affiliated Companies.

(e) Notwithstanding any provision in the Plan to the contrary:

(i) 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, to be paid or commence to be paid at any time following his termination of employment if he elects such distribution by written instrument delivered to the Committee prior to the date of his termination of employment. Such distribution shall be made in a method described in Section 4.9(d), as elected by the Participant.

(ii) A Participant may modify his election as to the form or time of distribution of his Post-2004 Benefit applicable to amounts credited to his Supplemental Accounts, and earnings thereon, if (A) such election does not take effect until at least 12 months after the date on which the election is made, (B) 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 (C) 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. Any such election shall apply to the entire portion of the Post-2004

Benefit that is not subject to an election previously made pursuant to this Section 4.9(e).

(iii) 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 (ii) on or before December 31, 2006; provided that such election (A) applies only to amounts that would not otherwise be payable in calendar year 2006, and (B) shall not cause an amount to be paid in calendar year 2006 that would not otherwise be payable in such year.

(f) 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.

ARTICLE V
FORFEITURES

5.1 Forfeiture of Supplemental Benefit, Supplemental Surviving Spouse Benefit, Supplemental Company Account #2 and Additional Supplemental Contribution Account. Notwithstanding any other provisions of the Plan, including the provisions of Sections 4.5(c)(iv) and 7.3, (a) if the employment of a Participant with the Company and all Affiliated Companies terminates due to Cause, or (b) if a Participant during his employment with the Company and all Affiliated Companies or at any time during the one-year period after the termination of such employment violates the covenant not to compete with the Company and its Affiliated Companies set forth in Section 5.3, all rights of the Participant and his Surviving Spouse to a Supplemental Retirement Benefit or a Supplemental Surviving Spouse Benefit, to a Supplemental Company Account #2, and to the Participant’s Additional Supplemental Contribution Account (including the vested and unvested portions) shall be forfeited and shall be retained by the Company free of any and all claims of the Participant, his Surviving Spouse or any other person claiming with respect to the Participant or his Surviving Spouse.

5.2 Termination For Cause. For purposes of this Section, a termination for Cause shall mean termination of a Participant’s employment by the Company or any Affiliated Company because of the Participant’s final, non-appealable conviction of a felony that involves bribery or embezzlement or fraud against the Company.

5.3 Covenant Not to Compete. A Participant shall not, during the term of the Participant’s employment with the Company and all Affiliated Companies, and for a period of one year thereafter, without the Company’s express written consent, directly or indirectly, alone or as a member of a partnership, group, or joint stock venture, or as an employee, officer, director or stockholder of any corporation, or in any capacity (a) engage in any activity that is competitive with any of the businesses conducted by the Company or its Affiliated Companies at the time of the Participant’s termination of employment, provided that the foregoing provision

shall not be deemed to prohibit the Participant from purchasing for investment any securities or interest in any publicly-owned organization that is competitive with the business of the Company and its Affiliated Companies, so long as the Participant’s investment in such organization does not exceed the lesser of one percent of its total outstanding equity securities or $250,000; (b) solicit in connection with any activity that is competitive with any of the businesses of the Company and its Affiliated Companies at the time of the Participant’s termination of employment, any then current customers or suppliers of the Company and its Affiliated Companies; (c) use the name “AAR” or any variant thereof; or (d) actively solicit, directly or indirectly, any employee or induce any then current customer or supplier of the Company or any of its Affiliated Companies to terminate or materially change the employee’s, customer’s or supplier’s relationship with the Company or any Affiliated Company.

5.4 Exception. In the event of a Participant’s termination of employment with the Company under circumstances that trigger Change in Control employment termination benefits under the change in control provisions of an employment agreement or severance and change in control agreement between the Participant and the Company, the provisions of subsections 5.1, 5.2 and 5.3 above shall be deemed waived by the Company and null and void.

ARTICLE VI

6.1 Administration by the Committee. The Committee shall be responsible for the general operation and administration of the Plan and for carrying out the provisions thereof.

6.2 General Powers of Administration. All provisions set forth in the Qualified Retirement Savings Plan with respect to the administrative powers and duties of the Committee, expenses of administration, and procedures for filing claims, shall also be applicable with respect to the Plan. The Committee shall be entitled to rely conclusively upon all tables, valuations, certificates, opinions and reports furnished by any actuary, accountant, controller, counsel or other person employed or engaged by the Committee with respect to the Plan.

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.

7.2 Effect of Amendment or Termination.

(a) (a)No amendment or termination of the Plan shall (i) directly or indirectly deprive any current or former Participant or Surviving Spouse of all or any portion of any Supplemental Retirement Benefit or Supplemental Surviving Spouse Benefit, the right to which has accrued prior to the effective date of such amendment or termination, or which would be payable if the Participant terminated employment for any reason, including death, on such effective date, or (ii) directly or indirectly reduce the balance of any

Supplemental Account held hereunder as of the effective date of such amendment or termination.

(b) Upon termination of the Plan, distribution of Supplemental Retirement Benefits and Supplemental Surviving Spouse Benefits, and of amounts in the Supplemental Accounts, shall be made to Participants, their Surviving Spouses or beneficiaries as soon as administratively feasible following the date of Plan termination, and within the timeframe permitted by regulations issued under Code Section 409A, in the manner described in Sections 3.4 and 4.9(d) of the Plan, except that payment of the Participant’s Post-2004 Benefit shall be made only at the time set forth in Sections 3.4 and 4.9(d) unless otherwise permitted by regulations issued under Code Section 409A. If the Plan is terminated in connection with a Change in Control, then immediately prior to such Change in Control, the Supplemental Account of each Participant who is then employed by the Company or an Affiliated Company shall be credited with a pro rata portion of the Supplemental Additional Company Contribution and Supplemental Profit Sharing Contribution made on behalf of the Participant for the immediately preceding Plan Year, with such pro rata amount to be determined by multiplying the entire amount of such Supplemental Contributions for the prior Plan Year by a fraction, the numerator of which is the number of full months that have elapsed in the Plan Year in which the Plan is terminated as of the date of such termination and the denominator of which is 12. Except as set forth in the immediately preceding sentence, no additional Supplemental Retirement Benefits or Supplemental Surviving Spouse Benefits shall be earned after termination of the Plan, and no additional credits of Supplemental Contributions shall be made to the accounts of Participants after termination of the Plan, but the Company shall continue to credit gains and losses to accounts pursuant to Section 4.8 until the balances of the Supplemental Accounts have been fully distributed to Participants or their beneficiaries.

7.3 Effect of a Change in Control. Notwithstanding Sections 7.1 and 7.2 above, in the event of a Change in Control, (i) the unvested portion of the Supplemental Account of each Participant who is then employed by the Company or an Affiliated Company shall become fully vested and nonforfeitable, (ii) the Plan shall continue in effect as to any Participant or Surviving Spouse who is a Participant or Surviving Spouse immediately prior to a Change in Control, and (iii) no amendment to or termination of the Plan shall be effective as to any such Participant or Surviving Spouse to the extent the effect of such amendment or termination would be to reduce such Participant’s or Surviving Spouse’s benefits or rights under the Plan from those available to such Participant under the Plan immediately prior to any such amendment or termination.

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. Upon such termination of participation, distribution of the Supplemental Retirement Benefit, Supplemental Surviving Spouse Benefit, and amounts in the Supplemental Accounts, as applicable, to such Participant, determined as of the date of termination of participation, shall be made to such Participant, his Surviving Spouse or beneficiaries either (a) in the manner and at the time described in Articles III and IV of the Plan, or (b) in the sole discretion of the Company, only with respect to the part of the Pre-2004

Benefit applicable to such Benefit and Accounts, in a lump sum payment as soon as practicable following such termination of participation. No additional Supplemental Retirement Benefit or Surviving Spouse Benefit shall be earned by such Participant after termination of his participation in the Plan with respect to such benefits, and no additional credits of Supplemental Contributions shall be made to the Supplemental Accounts of such Participant after termination of his participation in the Plan with respect to such benefits, but the Company shall continue to credit earnings, gains and losses to existing Supplemental Accounts of such Participant pursuant to Section 4.8 until the balances of such Supplemental Accounts have been fully distributed to the Participant or his beneficiaries.

ARTICLE VIII
GENERAL PROVISIONS

8.1 Participants’ Rights Unsecured. Except as set forth in Section 8.2, 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 Retirement Benefits, Surviving Spouse Benefits or Supplemental Accounts of Participants shall constitute general assets of the Company.

8.2 Trust Agreement. Notwithstanding the provisions of Section 8.1:

(a) The Company has entered into an irrevocable 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 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.

(b) The Company shall make contributions to the Trust annually for the purpose of accumulating assets sufficient to fully fund Participants’ vested and unvested Supplemental Accounts. The Trust Agreement shall include such provisions as are applicable with respect to the investment and reinvestment of Supplemental

Contributions and Supplemental Accounts pursuant to directions given by Participants to the Company and transmitted by the Company to the Trustee pursuant to paragraph (f) of Section 4.8.

8.3 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, including the vesting provisions, 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 Retirement Savings Plan applicable to a Qualified Salary Deferral Contribution, a Qualified Company Contribution or a Qualified Profit Sharing Contribution, including the vesting provisions, shall also be applicable to the respective Supplemental Salary Deferral Contribution, Supplemental Company Contribution and Supplemental Profit Sharing Contribution to be made hereunder. The Additional Supplemental Company Contribution shall be subject to the same terms and conditions of the Qualified Retirement Savings Plan as is the Supplemental Company Contribution.

8.4 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.

8.5 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.

8.6 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.

8.7 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.

8.8 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 termination of employment with the Company and all Affiliated Companies, or the 15th day of the third month following such termination of employment.

8.9 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.

8.10 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.

8.11 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.

8.12 Disputed Benefits; Limitations on Liability. If there is a dispute as to whether a Participant (or the Participant’s Surviving Spouse or beneficiary) is due a benefit under Article III or Article IV of the Plan, and the Participant prevails in the dispute, the Company shall reimburse the Participant for all reasonable expenses, including legal fees, incurred by the Participant in connection with such dispute. Such reimbursement shall be made within 30 days of the Participant’s submission of an invoice following resolution of the dispute. If not already included, the Company shall pay interest on any deferred payment of Plan benefits to the Participant, based on the 10-year Treasury bond rate in effect on the date the dispute is resolved, from the date that payment(s) of Plan benefits should have been made or commenced. Subject to the preceding sentence, 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.

8.13 Tax Savings. Notwithstanding 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.
