In addition, notwithstanding anything herein to the contrary, neither Vencor, Inc. nor any Affiliate or Associate of Vencor, Inc. shall be deemed to be an Acquiring Person solely because one or more Affiliates or Associates of Vencor, Inc. hereafter acquire Beneficial Ownership, collectively, of not more than 10,000 shares of Common Stock, provided that such Persons acquired such Beneficial Ownership without any plan or intention to seek or affect control of the Company. In addition, the Company, any wholly owned Subsidiary of the Company and any employee stock ownership or other employee benefit plan of the Company or a wholly owned Subsidiary of the Company shall not be an Acquiring Person. 2.
