Section 2(b) is amended by adding the following sentence to the end thereof:

“Payment of a bonus under this Section 2(b) shall be made no later than March 15 following the calendar year in which it was earned.”

Section 2(e) is amended in its entirety to provide as follows:

“(e) Expense Reimbursement. The Company shall, in accordance with and to the extent of its policies applicable to its executive officers generally, pay all business expenses reasonably incurred by Executive in performing her duties under this Agreement. Executive shall account promptly for all such business expenses in the manner prescribed by the Company and shall submit, on request, all records necessary to confirm the business purpose for such expenses in accordance with the Company’s expense reimbursement policies. Notwithstanding the foregoing, for compliance with Code Section 409A, (i) the Company shall provide any reimbursement under this Section 2(e) no later than the last day of the calendar year following the calendar year in which the Executive incurs the business expense, if timely submitted by the Executive pursuant to the Company’s policies; (ii) in no event shall the amount of business expenses reimbursed by the Company in one taxable year affect the amount of business expenses eligible for reimbursement in any other taxable year, and (iii) the right to reimbursement of business expenses is not subject to liquidation or exchange for another benefit.”

Section 2(f) is amended in its entirety to provide as follows:

“(f) Directed Executive Compensation Program. To the extent the Company either continues or maintains a Directed Executive Compensation Program, Executive shall be entitled to participate in such program at an initial level of not less than fifty-five thousand dollars ($55,000) per annum. Notwithstanding the foregoing, for compliance with Code Section 409A, (i) the Company shall provide any reimbursement for expenses covered by such Program no later than the last day of the calendar year following the calendar year in which the Executive incurs the expense, if timely submitted by the Executive pursuant to the Company’s policies; (ii) in no event shall the amount of expenses reimbursed by the Company in one taxable year affect the amount of expenses eligible for reimbursement in any other taxable year, and (iii) the right to reimbursement of expenses is not subject to liquidation or exchange for another benefit.”

“(vi) Severance Pay shall be paid in substantially equal monthly installments (or more frequent periodic installments corresponding to the Company’s normal payroll practices for Executive employees) during the Severance Period. Notwithstanding the preceding sentence, such installments shall commence on the first day of the seventh month following the Executive’s Eligible Separation from Service. Any installments that would have been paid during the first six months following the Executive’s Eligible Separation from Service, but for the six month delay in the preceding sentence, shall be paid in a single lump sum on the first day of the seventh month following the Executive’s Eligible Separation from Service, together with interest at the prime rate (as published in The Wall Street Journal) in effect on the date of the Eligible Separation from Service.”

Section 4(c)(i)(A) is amended in its entirety to provide as follows:

“(A) continued participation for her (and her spouse and their eligible dependents) in the Company’s health and life insurance benefit plans on the same basis (excluding payment of contributions for health benefit plans but including payment of contributions for life insurance benefit plans) as apply to active employees from time to time; provided that the Executive and her spouse and their eligible dependents assume the cost, on an after-tax basis for health benefit plan coverage. The health and life insurance benefit plan coverage (including coverage for her spouse and their eligible dependents, as applicable) shall terminate prior to the end of the Severance Period when Executive becomes entitled to health and life insurance benefit plan coverage (whether or not comparable to plans of the Company) from any successor employer; and provided further that if the Company determines that this coverage is likely to result in negative tax consequences to the Executive, the Company will use its reasonable best efforts to make other arrangements to provide a substantially similar benefit to the Executive that does not have such negative tax consequences. Any right of the Executive to reimbursements or in-kind benefits provided under the health benefit plans during the Severance Period or earlier termination date as provided in the preceding sentence shall be made consistent with Treasury Regulation Section 1.409A-3(i)(1)(iv) and the following shall apply: (i) such reimbursements or in-kind benefits shall be made on or before the last day of the Executive’ taxable year after the taxable year during which the Executive incurred the health benefit expense to which the health benefit claim relates, (ii) any health benefit expenses eligible for payment under a health benefit plan in one calendar year shall not affect the health benefit expenses eligible for payment in a subsequent calendar year and (iii) the right to receive coverage under a health benefit plan is not subject to liquidation or exchange for another benefit;”.

Within the period beginning ten (10) days before and ending ten (10) days after January 31 of the calendar year following the calendar year in which the Eligible Separation from Service occurs and continuing for such twenty-one (21)-day period each calendar year thereafter through the calendar year following the calendar year in which the Executive’s health benefit plan coverage ends pursuant to this paragraph, the Company will make a payment to the Executive equal to the amount the Executive paid during the immediately preceding calendar year for health benefit plan continuation coverage described in this paragraph that exceeds the amount that the Executive would have paid if the Executive paid for such continued health benefit plan coverage on the same basis as applicable to active employees, provided that each such cash payment by the Company pursuant to this paragraph shall be considered a separate payment and not one of a series of payments for purposes of Section 409A;”
