If the Company experiences a Change of Control, the Retirement Benefit Eligible Executive and/or his spouse shall be entitled to participate in the medical and dental benefits that the Acquiror makes available to eligible retirees at the equivalent cost applicable to the Executive as further provided in Section 16.3.4.”

(c) Section 10.2 of the Agreement is deleted in its entirety and replaced with the language set forth below such that Section 10.2 in its entirety is as follows:

(d) Section 16.3.4 of the Agreement is deleted in its entirety and replaced with the language set forth below such that Section 16.3.4 of the Agreement in its entirety is as follows:

“Health and Welfare Benefits. After a Change of Control, Executive and such Executive’s spouse and dependents (as defined in Code Section 152) (collectively, a “Covered Person”) shall be eligible to participate in the health and welfare benefits (including but not limited to medical and dental benefits) provided by the Company after such Change of Control; provided that, if such health and welfare benefits provided by the Company are terminated after such Change of Control, then the Covered Persons shall be eligible to participate in (i) if Executive is an employee of the Acquiror the benefits the Acquiror provides to similarly situated Covered Persons and (ii) if Executive ceases to be an employee of Acquiror, then to Acquiror Retiree Benefits. For purposes of this Section, the term “Acquiror” shall mean the Person (including an Affiliate thereof) acquiring the Company or all or substantially all of the assets of the Company including any controlled or controlling Affiliate thereof. “Acquiror Retiree Benefits” shall mean the health and welfare benefits that the Acquiror makes available, from time to time, to eligible retirees of Acquiror, including officers of the Company who become officers of the Acquiror as a result of the Change of Control, whether such benefits are provided directly through the Acquiror or through one or more controlled or controlling Affiliates of the Acquiror pursuant to one or more plans of such persons subject to the remaining provisions of this Section. Prior to age 65, the costs of Acquiror Retiree Benefits payable with respect to Covered Persons hereunder shall be paid by the Executive in an amount not to exceed the costs of Acquiror health and welfare benefits generally paid by the then-current officers of the Acquiror (evaluating such Acquiror on a consolidated basis for purposes of ascertaining the amount of costs paid). Upon the Executive reaching age 65, all Acquiror Retiree Benefits under this Section (including all health and welfare benefits available to any Covered Person) shall terminate if such Acquiror Retiree Benefits terminate for all of the then-retired officers of the Acquiror. At any time before or after age 65, if Executive becomes eligible for customary coverage through another employer’s group health coverage, the coverage provided under this Section 16.3.4 shall be terminated, provided, however, that if, subsequent to such termination of coverage, Executive experiences a termination of employment with an employer and such termination of employment results in the loss of group health coverage, including a qualifying event under the Consolidated Omnibus Reconciliation Act of 1986, as amended (COBRA), Executive, upon written to notice to Acquiror of such loss of coverage shall begin receiving Acquiror Retiree Benefits for himself and for any other Covered Person as are permitted under the plan or plans pursuant to which Acquiror Retiree Benefits will be provided (for example, Executive Only, Executive plus spouse, Executive plus family). Notwithstanding

“PROVISION OF IN-KIND BENEFITS

The provision of in-kind benefits pursuant to Section 10.2 and Section 16.3.4 shall be provided in accordance with Treas. Reg. § 1.409A-3(i)(1)(iv).

Reg. § 1.409A-3(i)(1)(iv)(B)).”
