For purposes of this Agreement, “Good Reason” shall mean, without the Executive’s consent, the occurrence of any one or more of the following events: (i) material diminution in the nature or scope of the Executive’s responsibilities, duties or authority, provided that neither (x) the Company’s failure to continue the Executive’s appointment or election as a director or officer of any of its Affiliates nor (y) any diminution in the nature or scope of the Executive’s responsibilities, duties or authority that is reasonably related to a diminution of the business of the Company or any of its Affiliates shall constitute “Good Reason”; (ii) a material reduction in the Executive’s base salary; (iii) a material breach by the Company of any material provision of this Agreement or any other material agreement with Executive; or (iv) relocation of the Executive’s principal place of business more than forty (40) miles from the then-current location of the Executive’s principal place of business.

(e)        This Agreement shall automatically terminate in the event of the Executive’s death during employment. The Company may terminate the Executive’s employment, upon notice to the Executive, in the event the Executive becomes disabled during employment and, as a result, is unable to continue to perform substantially all of his material duties and responsibilities under this Agreement for one-hundred and twenty (120) days during any period of three hundred and sixty-five (365) consecutive calendar days. If any question shall arise as to whether the Executive is disabled to the extent that the Executive is unable to perform substantially all of his material duties and responsibilities for the Company and its Affiliates, the Executive shall, at the Company’s request and expense, submit to a medical examination by a physician selected by the Company to whom the Executive or the Executive’s guardian, if any, has no reasonable objection to determine whether the Executive is so disabled and such determination shall for the purposes of this Agreement be conclusive of the issue.

Exhibit A

Payments Subject to Section 409A

1.             Subject to this Exhibit A, any severance payments that may be due under the Agreement shall begin only upon or following the date of the Executive’s “separation from service” (determined as set forth below) which occurs on or after the termination of Executive’s employment. The following rules shall apply with respect to distribution of the severance payments, if any, to be provided to Executive under the Agreement, as applicable:

(a)          It is intended that each installment of the severance payments under the Agreement provided under shall be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor Executive shall have the right to accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A.

(b)          If, as of the date of Executive’s “separation from service” from the Company, Executive is not a “specified employee” (within the meaning of Section 409A), then each installment of the severance payments shall be made on the dates and terms set forth in the Agreement.

(c)           If, as of the date of Executive’s “separation from service” from the Company, Executive is a “specified employee” (within the meaning of Section 409A), then:

(i)          Each installment of the severance payments due under the Agreement that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when Executive’s separation from service occurs, be paid within the short-term deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid on the dates and terms set forth in the Agreement; and

(ii)         Each installment of the severance payments due under the Agreement that is not described in this Exhibit A, Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following Executive’s “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, Executive’s death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following Executive’s separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments if and to the maximum extent that that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of Executive’s second taxable year following the taxable year in which the separation from service occurs.

2.             The determination of whether and when Executive’s separation from service from the Company has occurred shall be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this Exhibit A, Section 2, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and 414(c) of the Code.

3.             The Company makes no representation or warranty and shall have no liability to Executive or to any other person if any of the provisions of the Agreement (including this Exhibit) are determined to constitute deferred compensation subject to Section 409A but that do not satisfy an exemption from, or the conditions of, that section.
