For purposes of the Plan, the phrase “permitted by Section 409A of the Code,” or words or phrases of similar import, shall mean that the event or circumstance shall only be permitted to the extent it would not cause an amount deferred or payable under the Plan to be includible in the gross income of a Participant or Beneficiary under Section 409A(a)(1) of the Code.

ARTICLE X - MISCELLANEOUS

10.1. Unfunded Plan. This Plan is an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of “management or highly-compensated employees” within the meaning of Sections 201, 301, and 401 of ERISA, and therefore is exempt from the provisions of Parts 2, 3 and 4 of Title I of ERISA.

10.2. Unsecured General Creditor. Notwithstanding any other provision of this Plan, Participants and Participants’ Beneficiaries shall be unsecured general creditors, with no secured or preferential rights to any assets of Company or any other party for payment of benefits under this Plan. Any property held by Company for the purpose of generating the cash flow for benefit payments shall remain its general, unpledged and unrestricted assets. Company’s obligation under the Plan shall be an unfunded and unsecured promise to pay money in the future.

10.3. Trust Fund. Company shall be responsible for the payment of all benefits provided under the Plan. At its discretion, Company may establish one (1) or more trusts, with such trustees as the Board may approve, for the purpose of assisting in the payment of such benefits. The assets of any such trust shall be held for payment of all Company’s general creditors in the event of insolvency. To the extent any benefits provided under the Plan are paid from any such trust, Company shall have no further obligation to pay them. If not paid from the trust, such benefits shall remain the obligation of Company.

10.4. Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are, expressly declared to be unassignable and non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgements, alimony or separate maintenance owed by a Participant or any other person, nor be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency.

10.5. Not a Contract of Employment. This Plan shall not constitute a contract of employment between Company and the Participant. Nothing in this Plan shall give a Participant the right to be retained in the service of Company, or to interfere with the right of the Company to discipline or discharge a Participant at any time.

10.6. Protective Provisions. A Participant will cooperate with Company by furnishing any and all information requested by Company, in order to facilitate the payment of benefits hereunder, and by taking such physical examinations as Company may deem necessary and taking such other action as may be requested by Company.

10.7. Governing Law. The provisions of this Plan shall be construed and interpreted according to the laws of the State of Delaware, except as preempted by federal law.

10.8. Validity. If any provision of this Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but this Plan shall be construed and enforced as if such illegal and invalid provision had never been inserted herein.

10.9. Notice. Any notice required or permitted under the Plan shall be sufficient if in writing and hand delivered or sent by registered or certified mail. Such notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification. Mailed notice to the Committee shall be directed to the Company’s address. Mailed notice to a Participant or Beneficiary shall be directed to the individual’s last known address in company’s records.

10.10. Successors. The provisions of this Plan shall bind and inure to the benefit of Company and its successors and assigns. The term successors as used herein shall include any corporate or other business entity which shall, whether by merger, consolidation, purchase or otherwise acquire all or substantially all of the business and assets of Company, and successors of any such corporation or other business entity.
