2. Severance upon Termination in Connection with a Change of Control. Section 3(b)(i) of the Agreement will be amended and

provided (A) the Executive constitutes a qualified
beneficiary, as defined in Section 4980B(g)(1) of the Code, and (B) the Executive elects continuation coverage pursuant to COBRA within the time period prescribed pursuant to COBRA, the Company will reimburse the COBRA premiums for

foregoing, if the Executive becomes entitled to benefits pursuant to Section 3(a) or 3(b) of this Agreement, this Agreement will not terminate until, but will terminate at, such time that all of the obligations of the parties hereto with
