III-6. LIMIT OF TRUSTEE"S RESPONSIBILITY. No power, duty or responsibility is imposed upon the trustee under the plan, except as set forth in this agreement or the plan.

III-7. COMMON FUND. If more than one employer has adopted the plan, the trustee shall not be required to make any separate investment of the trust fund for the account of the plan as applied to the several employers and may administer and invest all contributions made under the plan as one trust fund. If, for any purpose, it becomes necessary to determine as of any date the portion of the trust fund allocable to all or any group of participants employed by any one of the employers, such portion shall be determined by the plan administrator, taking into consideration the relative aggregate employer contributions to the trust fund with respect to such participants, the relative aggregate benefits paid and payable from the trust fund to or on behalf of such participants, and such other factors as the plan administrator deems appropriate. Any such determination by the plan administrator shall be binding upon all of the employers, participants and all other persons. The trustee will have no duty or responsibility to question any determination or direction by the plan administrator under this paragraph III-7. III-8. LOANS. The plan administrator shall be the named fiduciary exclusively responsible for the administration of the participant loan program pursuant to the terms of the plan, including responsibility for issuing and maintaining custody of promissory notes and other documentation pertaining to such loans, and for all related loan disclosure and recordkeeping matters. Loan payments shall be collected by the plan administrator and remitted to the trustee, who shall invest such repayments among the investment funds in the proportions directed by the plan administrator. Promissory notes held by the plan administrator shall not be included as assets of the trust fund -9- for purposes of the reports and accounts furnished by the trustee. The trustee shall not be liable for any actions taken by the plan administrator under this paragraph. ARTICLE IV TRUST INVESTMENTS IV-1. INVESTMENT BY TRUSTEE.

IV-2. INVESTMENT MANAGER-DIRECTED INVESTMENT. If the plan administrator has appointed an investment manager pursuant to paragraph III-4 of the trust, such investment manager shall have sole and exclusive authority and discretion to direct the trustee as to the investment of part or all of the assets of the trust fund and, except as provided by law, the trustee shall have no obligation with respect to the investment of such plan assets. IV-3. INVESTMENT FUNDS.

The plan administrator may direct the trustee to invest all or any part of the assets of an investment fund in employer securities, in accordance with the following provisions: (a) The term "employer security" means stock that is a qualifying employer security (as defined in Section 407(d)(5) of the Employee Retirement Income Security Act of 1974 ("ERISA")) issued by an employer of employees covered by the plan, or by an affiliate of such employer. (b) The plan administrator may direct the trustee to invest any portion of the assets of the trust fund (other than assets under the control of an investment manager appointed under paragraph III-4) in employer securities, may direct the trustee to sell any such securities held as an asset of the trust fund and may direct the trustee to accept a contribution from an employer in the form of employer securities; provided that, all such purchases and sales shall be for adequate consideration (as defined in Section 3(18) of ERISA) and shall meet the requirements exempting such transactions from the prohibited transaction provisions of ERISA and the Internal Revenue Code. Adequate consideration means: in the case of a security for which there is a generally recognized market, either (i) the price of the security prevailing on a national securities exchange that is registered under Section 6 of the Securities Exchange Act of 1934, or (ii) if the security is not traded on such a national securities exchange, a price not less favorable to the plan than the offering price for the security as established by the current bid and asked prices quoted by persons independent of the issuer and of any party in interest (as defined in Section 3(14) of ERISA); and in the case of an employer security (including an employer security acquired directly from the issuer) other than a security for which there is a generally recognized market, the fair market value of such security as determined in good faith by the plan administrator pursuant to the terms of the plan and in accordance with applicable law. The trustee will not undertake to value or be responsible for the valuation of employer -11- securities not traded on a national securities exchange. The trustee shall not be required to hire an independent valuation firm to value employer securities not traded on a national securities exchange. The trustee may rely on any valuation figure supplied by the plan administrator or the opinion of an independent valuation firm hired by the plan administrator, but shall have no duty to verify such opinion or valuation figure and shall not be responsible for any loss that results from reliance upon such opinion or valuation figure. The trustee may, in its sole discretion, direct the plan administrator to obtain an opinion of an independent valuation firm or may require that an additional valuation be obtained. (c) If securities issued by an employer are acquired from or sold to a party in interest, no commission shall be charged to the trust fund with respect to such acquisition or sale. (d) Directions to be given or furnished by the plan administrator to the trustee in accordance with the provisions of this paragraph shall be in writing or such other form of communication as is mutually acceptable to the plan administrator and the trustee. Absent any direction by the plan administrator, the trustee shall have no obligation or responsibility to acquire or sell any employer securities pursuant to the provisions of this paragraph and may invest any assets of the trust fund without regard to this paragraph. (e) The trustee shall not exercise any voting rights with respect to the securities of an employer unless directed by the plan administrator and shall not be liable for the voting of such securities, the failure to vote such securities if not directed by the plan administrator or the direct or indirect results of such voting or failure to vote. The plan administrator shall direct the trustee with respect to the exercise of stock subscription rights, conversion rights, warrants, options, tender offers, buy-sell arrangements and other rights or duties with respect to employer securities held by the -12- trust fund. The plan administrator also shall direct the trustee with respect to the disposition of any dividend income related to the employer securities held under the trust fund. (f) The plan administrator shall determine whether the employer securities purchased by the trust fund must be registered or must comply with any provision of the Securities Act of 1933 (the "Act") or any other state or federal law governing or pertaining to securities. If the plan administrator determines that such registration or other action is necessary, the plan administrator shall complete and file a Registration Statement under the Act or such other documentation as is required by applicable state or federal law. IV-5. TRUSTEE"S INVESTMENT OF AMOUNTS SUBJECT TO PARTICIPANT INVESTMENT DIRECTION.

(b) The trustee shall have the power to invest any portion of the assets in a participant"s investment account that is held in cash or cash equivalents in short term, fixed income investments pending receipt of instructions from the participant regarding the investment of his accounts. (c) Each participant shall indemnify and hold the trustee and the employer harmless for any losses suffered as a result of investments and reinvestments made by the trustee in good faith reliance upon any investment direction given by such participant in accordance with -13- this paragraph IV-5 and the terms of the plan. (d) The trustee shall have the power, right and duty to determine and report to the plan administrator, at such times as the plan administrator and the trustee shall agree upon, the fair market value (as determined in the sole discretion of the trustee) of the assets held for the benefit of each participant in accordance with this paragraph IV-5. The trustee shall have the right to rely on valuations prepared by third parties as to assets held by any such third party. (e) The trustee shall have the power, right and duty to provide to the plan administrator on each accounting date or as soon thereafter as practicable a statement showing the assets held for the benefit of each participant in accordance with this paragraph IV-5 and any expenses attributable to the acquisition and maintenance of such assets and expenses attributable to any assets disposed of since the last preceding accounting date. (f) On the written direction of a participant, given in accordance with the plan, the trustee shall liquidate for their fair market value (as determined by the trustee after consulting with the participant) all of the assets held for the benefit of the participant in accordance with this paragraph IV-5 and credit to such participant"s accounts under the plan the amount realized on such liquidation. (g) Notwithstanding paragraph III-5, all expenses incurred in connection with the sale, investment and reinvestment of assets in accordance with this paragraph IV-5 (such as custodial, maintenance, investment manager, brokerage, postage, express and insurance charges and transfer taxes) shall be charged to the appropriate accounts of a participant. (h) If required by law, the trustee reserves the right to disapprove any investment direction filed with the trustee. (i) Except to the extent otherwise required by law, the trustee is not liable or responsible for any loss resulting to accounts by reason -14- of any investment or reinvestment made by the trustee at the direction of a participant, and, therefore, the trustee is relieved of any duty to review from time to time such property included in a participant"s investment accounts. ARTICLE V GENERAL PROVISIONS V-1. ACTION BY EMPLOYERS. Any action required or permitted to be taken by an employer under the trust shall be by resolution of its Board of Directors, by resolution of a duly authorized committee of its Board of Directors, or by a person or persons authorized by resolution of its Board of Directors or such committee. V-2. WARRANTY. The employer warrants that all directions or authorizations by it or the plan administrator, whether for the payment of money or otherwise, will comply with the plan and this trust. V-3. DISAGREEMENT AS TO ACTS. If there is a disagreement between the trustee and anyone as to any act or transaction reported in any accounting, the trustee shall have the right to a settlement of its account by any proper court. V-4. COURTS. Except as otherwise provided by law, in case of any court proceedings involving an employer, the plan administrator, the trustee or the trust fund, only the employer or the plan administrator, as the case may be, and the trustee shall be necessary parties to the proceedings, and no other person shall be entitled to notice of process. A final judgment entered in any such proceedings shall be conclusive. V-5. EVIDENCE. Evidence required of anyone under this agreement may be by certificate, affidavit, document or other information which the person acting on it considers pertinent and reliable, and signed, made or presented by the proper party or parties. V-6. THIRD PARTIES. Except as otherwise provided by law, the trustee"s exercise or non-exercise of its powers and discretions in good faith shall be conclusive on all persons. No one shall be obliged to see to the application of any money paid -15- or property delivered to the trustee, except to the extent such person is acting as an investment manager as respects such money or property. The certificate of the trustee that it is acting according to this agreement will fully protect all persons dealing with the trustee. An insurance company or investment manager may assume that this agreement and the plan have not been amended or changed unless notice of such amendment or change is received by the investment manager or by the insurance company at its home office. V-7. NO REVERSION IN EMPLOYER. The employers shall have no right, title or interest in the trust fund, nor shall any part of the trust fund revert or be repaid to an employer, directly or indirectly, unless: (a) a contribution is made by such employer by mistake of fact and such contribution is returned to the employer within one year after payment to the trustee; or (b) a contribution conditioned on the deductibility thereof is disallowed as an expense for federal income tax purposes and such contribution (to the extent disallowed) is returned to the employer within one year after the disallowance of the deduction; or (c) the Internal Revenue Service initially determines that the plan, as applied to the employer, does not meet the requirements of Section 401(a) of the Internal Revenue Code, in which event, any trust assets attributable to contributions made by such employer shall be returned to it within one year of the date of the denial of qualification of the plan. The amount of any contribution that may be returned to the employer pursuant to subparagraph (a) or (b) above must be reduced by any portion thereof previously distributed from the trust fund and by any losses of the trust fund allocable thereto, and in no event may the return of such contribution cause any participant"s account balances to be less than the amount of such balances had the contribution not been made under the plan. V-8. INTERESTS NOT TRANSFERABLE. The interests of persons entitled to benefits under the plan are not subject to their debts or other obligations and, except as may be required by the tax withholding provisions of the Internal Revenue Code or any state"s income tax act or pursuant to a qualified domestic relations order as defined in Section 414(p) of the Internal Revenue Code, may not be voluntarily or involuntarily sold, -16- transferred, alienated, assigned or encumbered.

Any employee of an employer to whom the plan administrator or an employer has delegated any portion of its responsibilities under the plan, any person who is or was a director or officer of an employer, members and former members of the plan administrator, and each of them, shall, to the extent permitted by law, be indemnified and saved harmless by the employers (to the extent not indemnified or saved harmless under any liability insurance or other indemnification arrangement with respect to the plan or this trust) from and against any and all liability or claim of liability to which they may be subjected by reason of any act done or omitted to be done in good faith in connection with the administration of the plan or this trust or the investment of the trust fund, including all expenses reasonably incurred in their defense if the employers fail to provide such defense after having been requested to do so in writing. The trustee shall be indemnified and saved harmless by the employers with respect to any liability or claim of liability to which the trustee shall be subjected by reason of its compliance with any directions given in accordance with the provisions of the plan or this trust by an investment manager, the plan administrator or employers, or any person duly authorized by the plan administrator or the employers, or by reason of its failure to take any action with respect to any assets of the trust fund that are subject to investment direction from an investment manager or the plan administrator in the absence of direction from the investment manager or the plan administrator, including all expenses reasonably incurred in its defense if the employers fail to provide such defense after having been requested to do so in writing. V-10. LITIGATION BY PARTICIPANTS. If a legal action begun against the trustee, an employer or the plan administrator by or on behalf of any person results adversely to that person, or if a legal action arises because of conflicting claims to a participant"s or other person"s benefits, the cost to the trustee, the employers or the plan administrator of defending the action will be charged to the extent permitted by law to the sums, if any, which were involved in the action or were payable to the person concerned. -17- V-11. LIABILITIES MUTUALLY EXCLUSIVE. To the extent permitted by law, the trustee, an investment manager, the employers and each plan administrator member shall be responsible only for its own acts or omissions and neither the plan administrator nor the trustee shall be required to collect any contribution from an employer or any other person or to verify that it is in the proper amount.

V-12. WAIVER OF NOTICE. Any notice required under this agreement may be waived by the person entitled to such notice. V-13. CONTROLLING LAW. Except to the extent superseded by laws of the United States, the laws of Illinois shall be controlling in all matters relating to this agreement. V-14. GENDER AND NUMBER.
