Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees, within the meaning of Section 401 of ERISA. All payments pursuant to the Plan shall be made from the general funds of the Company and no special or separate fund shall be established or other segregation of assets made to assure payment. No Participant or other person shall have under any circumstances any interest in any particular property or assets of the Company as a result of participating in the Plan. Notwithstanding the foregoing, the Company may (but shall not be obligated to) create one or more grantor trusts, the assets of which are subject to the claims of the Companys creditors, to assist it in accumulating funds to pay its obligations under the Plan.
