ARTICLE 6 GENERAL PROVISIONS 6.1 Unfunded Benefits/Liability for Payment. All benefits payable under the Plan shall be paid out of the general assets of the Employer that employed the Participant at the time such benefit became payable (or, if applicable, the Employer that employed the Participant at the time of his termination without Cause or his death or disability). No Employer shall be liable for the benefit obligations of any other Employer hereunder. Any person who may have or claim any interest in or right to any compensation, payment or benefit payable hereunder, shall have solely the status of a general unsecured creditor of the Employer (or former Employer, if applicable) of the Participant and the Plan constitutes a mere promise by each such Employer to make benefit payments in the future. Nothing herein contained shall be construed to give to or vest in any person now or at any time in the future, any right, title, interest or claim in or to any specific asset, fund, reserve, account, insurance or annuity policy or contract or other property of any kind whatsoever owned by any Employer or in which any Employer may have any right, title or interest now or at any time in the future. It is the intention of the Employers and the Participants that the Plan be unfunded for tax purposes and for purposes of Title I of ERISA. 6.2 Withholding. Payments under the Plan are subject to such federal, state and local income tax withholding and all other federal, state and local taxes (including but not limited to Social Security) as are applicable. The applicable Employer shall withhold from any payments it makes under the Plan, all applicable federal, state and local withholding taxes. 6.3 Payment Restriction. Notwithstanding any provision of the Plan to the contrary, the payment of all or any portion of the amounts payable hereunder will be deferred to the extent that any amount payable, when added to any other compensation received or to be Page 6 received by the Participant in the same calendar year, would not be deductible by an Employer by reason of Section 162(m) of the Code. The amount to be deferred will equal the amount that otherwise would not be deductible by the Employer by reason of Section 162(m) of the Code, but in no event greater than the total amount otherwise payable hereunder. The deferred amount shall become payable on December 31 of the first succeeding calendar year in which such amount, when added to all other compensation received or to be received by the Participant in such calendar year, would not be non-deductible by the Employer by reason of Section 162(m) of the Code. The Committee, in its sole and absolute discretion, shall have the authority to waive this payment restriction (in whole or in part) upon the written request of the Participant. 6.4 Cumulative Benefits. The benefits provided to any Participant under this Plan are cumulative of, and are in addition to, all of the other benefits provided to such Participant under any other benefit plan maintained, sponsored or provided by an Employer, or any agreement between such Participant and an Employer. 6.5 Amendment or Termination. The Plan may not be amended in any way to reduce the benefits payable hereunder to a Participant or otherwise impair his ability to receive any amount due hereunder, without the prior written consent of the Participant. Notwithstanding the foregoing, the Plan shall terminate when all obligations to Participants have been satisfied in full. 6.6 Severability. If any term or condition of the Plan shall be invalid or unenforceable to any extent or in any application, then the remainder of the Plan, with the exception of such invalid or unenforceable provision, shall not be affected thereby and shall continue in effect and application to its fullest extent. 6.7 No Employment Rights. Neither the establishment of the Plan, any provisions of the Plan, nor any action of the Committee shall be held or construed to confer upon any employee the right to a continuation of employment by the Company or any Subsidiary. 6.8 Transferability of Rights. A Participant's rights to any benefit under the Plan are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors of the Participant. Any attempt to transfer or assign a benefit, or any rights granted hereunder, by a Participant shall, in the sole discretion of the Committee (after consideration of such facts as it deems pertinent), be grounds for terminating any rights of the Participant to any portion of the benefits not yet received by the Participant. 6.9 Governing Law. The Plan shall be construed, administered, and enforced according to the laws of the State of Ohio, except to the extent that such laws are preempted by the federal laws of the United States of America. In futherance of, but without limiting the foregoing, benefits hereunder shall comply with, and be administered in compliance with, the requirements of Section 409A of the code, as enacted by the American Jobs Creation Act of 2004, to the extent applicable. The venue for all actions or proceedings brought by the Company or any Participant arising out of or relating to the Plan shall be in the state or federal courts, as the case may be, located in Cleveland, Ohio. The Company and the Participants hereby irrevocably waive any objection which they now or hereafter may have to the laying of venue of any action or proceeding arising out of or Page 7 relating to the Plan brought in any such courts and any objection on the ground that any such action or proceeding in any such courts has been brought in an inconvenient forum. 6.10 Gender Neutrality.
