Article 9. Compliance with IRC Section 409A.

9.1

(a)The following rules shall apply with respect to distribution of the payments and benefits, if any, to be provided to the Executive under
Articles 7 or 8, as applicable:

(i)It is intended that each installment of the payments and benefits provided under Articles 7 or 8 shall be treated as a separate
payment for purposes of Section 409A of the Code and the guidance issued thereunder (Section 409A). Neither the Company nor the Executive shall have the right to accelerate or defer the delivery of any such payments or
benefits except to the extent specifically permitted or required by Section 409A.

(ii)If, as of the date of the separation from service of the Executive from the Company (determined as set forth below), the
Executive is not a specified employee (within the meaning of Section 409A), then each installment of the payments and benefits shall be made on the dates and terms set forth in Articles 7 or 8, as applicable.

---



(iii)If, as of the date of the separation from service of the Executive from the Company, the Executive is a specified
employee (within the meaning of Section 409A), then:

(1)Each installment of the payments and benefits due under Articles 7 or 8, as applicable, that, in accordance with the dates and terms set
forth herein, will in all circumstances, regardless of when the separation from service occurs, be paid within the Short-Term Deferral Period (as hereinafter defined) shall be treated as a short-term deferral within the meaning of Treasury
Regulation § 1.409A-1(b)(4) to the maximum extent permissible under Section 409A. For purposes of this Agreement, the Short-Term Deferral Period means the period ending on the later of the 15thday of the third month following the end of the Executives tax year in which the separation from service occurs and the 15thday of
the third month following the end of the Companys tax year in which the separation from service occurs; and

(2)Each installment of the payments and benefits due under Articles 7 or 8 that is not described in clause (1), above, and that would, absent
this subsection, be paid within the six-month period following the separation from service of the Executive 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, the 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 the 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 and
benefits 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 § 1.409A-1(b)(9)(iii) must be paid no later than the last day of the Executives second
taxable year following his taxable year in which the separation from service occurs.

(b)The determination of whether and when a separation from service of the Executive from the Company has occurred shall be made and in a
manner consistent with, and based on the presumptions set forth in, Treasury Regulation § 1.409A-1(h). Solely for purposes of this Section 4.4(b), 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.

(c)All reimbursements and in-kind benefits provided under the Agreement shall be made or provided in accordance with the requirements of
Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A.

(d)The parties acknowledge and agree that the interpretation of Section 409A and its application to the terms of this Agreement is uncertain
and may be subject to change as additional guidance and interpretations become available. Anything to the

contrary herein notwithstanding, all benefits or payments provided by the Company to the Executive that would be deemed to constitute nonqualified deferred compensation within the meaning of Section 409A are intended
to comply with Section 409A. If, however, any such benefit or payment is deemed to not comply with Section 409A, the Company and Executive agree to renegotiate in good faith any such Severance Benefit or CIC Severance Benefit (including, without
limitation, as to the timing of any such payment payable hereof) so that either (i) Section 409A will not apply or (ii) compliance with Section 409A will be achieved;provided,however, that any resulting renegotiated terms shall provide to Executive the after-tax economic equivalent of what otherwise has been provided to Executive pursuant to the terms of this
Agreement, andprovidedfurther, that any deferral of payments or other benefits shall be only for such time period as may be
required to comply with Section 409A.

(e)If, notwithstanding the preceding provisions of Sections 7.4, 7.6 or 8.4, any Severance Benefit or CIC Severance Benefit (or any
acceleration thereof) (the Payments) made or provided to the Executive or for his benefit in connection with this Agreement or the Executives employment with the Company or the termination thereof, are determined to be subject to
the tax imposed by Section 409A(a)(1)(B) or any interest or penalties with respect to such taxes (such taxes, together with any such interest and penalties, are collectively referred to as the Section 409A Tax), then the Company will
promptly pay to the Executive an additional amount (a Gross-Up Payment) such that the net amount the Executive retains after paying any applicable Section 409A Tax and any federal, state or local income or FICA taxes on such Gross-Up
Payment shall be equal to the amount the Executive would have received if the Section 409A Tax were not applicable to the Payments. All determinations of the Section 409A Tax and Gross-Up Payment, if any, will be made by tax counsel or other tax
advisers designated by or acceptable to the Executive. For purposes of determining the amount of the Gross-Up Payment, if any, the Executive will be deemed to pay federal income tax at the highest marginal rate of federal income taxation in the
calendar year in which the Payments are made and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executives residence on the date the Payments are made, net of the maximum reduction in
federal income taxes that could be obtained from deduction of such state and local taxes. If the Section 409A Tax is determined by the Internal Revenue Service, on audit or otherwise, to exceed the amount taken into account hereunder in calculating
the Gross-Up Payment (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross-Up Payment), the Company must make another Gross-Up Payment with respect to such excess (plus any interest,
penalties or additions payable by the Executive with respect to such excess) within ten (10) calendar days immediately following the date that the amount of such excess is finally determined. The Company and the Executive must each reasonably
cooperate with the other in connection with any administrative or judicial proceedings concerning the existence or amount of liability for Section 409A Tax with respect to the total Payments.

Article 10. Creation of Rabbi Trust

10.1    In the event that a CIC Severance Payment is required to be made on the day that

---



is six months and one day from the Executives separation from service pursuant to Section 9.1(a)(iii), the Company shall deposit the full amount of such CIC Severance Payment in cash in a rabbi trust for the
benefit of the Executive as soon as reasonably practicable following the Executives separation from service. The rabbi trust shall be governed by the terms of a trust agreement reasonably acceptable to the parties, shall be
irrevocable and shall provide that the Company, or any successor thereto, may not, directly or indirectly, use or recover any assets of the rabbi trust until such time as the assets of the trust have been paid to the Executive hereunder, subject
only to the claims of creditors of the Company in the event of its insolvency or bankruptcy. The assets held by the rabbi trust shall be transferred to Executive one day following the six-month anniversary of the Executives separation from
service from the Company (the Payment Date). The assets delivered to Executive pursuant to the rabbi trust shall reflect any investment gain or loss (as the case may be) on the CIC Severance Benefit from the date the assets
comprising the CIC Severance Benefit were deposited into such rabbi trust until the Payment Date. The Company, or any successor thereto, shall deliver and pay over to the appropriate taxing authorities if and when due all amounts subject to
withholding with respect to the transfer of the CIC Severance Benefit to the rabbi trust and the transfer of the assets of the rabbi trust to Executive (as adjusted for any investment gain or loss) on the Payment Date, and shall instruct the trustee
to transfer to the Executive such assets (in such form and asset class as has been deposited initially into the rabbi trust), without any further reduction for withholding for federal, state and local taxes other than any additional amounts required
to be withheld on any amounts transferred to the Executive that were not included in the initial computation of the CIC Severance Benefit.
