Permanent Disability means the permanent and total inability of a Participant to perform the duties of his employment with the Company by reason of physical or mental impairment, as determined by the Committee based upon the written opinion of a licensed physician approved by it. The Committee, acting upon the written advice of such physician, will determine the existence of and the date on which a Permanent Disability occurs. Subject to the provisions of Section 8.12, the final decision of the Committee with respect to Permanent Disability is conclusive for all purposes of the Plan. Notwithstanding the foregoing or any Supplements to the Plan, effective with respect to claims for benefits received on or after January 1, 2002, the previous paragraph shall not apply, and instead the following shall apply. Permanent Disability means that the Participant has been determined to be disabled under the applicable long-term disability plan of the Company in which the Participant participates. With respect to any Supplement, the determination of whether a Participant satisfies the conditions necessary to be considered Totally and Permanently Disabled, Permanently Incapacitated, or any similar term shall be made solely based upon a determination under the applicable long-term disability plan of the Company in which the Participant participates that the Participant is disabled. The preceding paragraphs of this Section 2.28 shall not apply with respect to any Participant subject to Supplement T. Instead, Article One, Section 39, of the Muncie Plan attached as Supplement T shall continue to apply with respect to any Participant subject to Supplement T.

Primary Social Security Benefit means the annual amount available to the Participant when he attains Social Security Retirement Age (or upon actual retirement, if later) under the provisions of Title II of the Social Security Act in effect at the time of his Termination Date, without regard to any increase in the Social Security Taxable Wage Base, or benefit levels that take effect thereafter. However, if his Termination Date occurs prior to the date he attains Social Security Retirement Age, the Plan will estimate the Participant s Primary Social Security Benefit by assuming continuation of his Earnings until he attains Social Security Retirement Age at the same rate as in effect during the last complete Plan Year before his Termination Date. The computation of the Participant s Primary Social Security Benefit assumes that his Earnings for years prior to the last complete Plan Year before his Termination Date are his Earnings during the last complete Plan Year before his Termination Date discounted at 6% per year. However, a Participant may submit documentation of actual salary history (in accordance with Section 5.8) for the Plan to use to determine Earnings in computing his Primary Social Security Benefits in lieu of the assumptions set forth in this Section. The Plan will disregard the fact that a Participant does not actually receive a Primary Social Security Benefit because of failure to apply, continuance of work, or any other reason. Section 2.32 Qualified Military Service. Qualified Military Service means service in the uniformed services (as defined in chapter 43 of title 38, United States Code) by an individual if such individual is entitled to reemployment rights under such chapter with respect to such service.

Any individual who is absent from employment with the Company by reason of service in the uniformed service and knowingly provides written notice of intent not to return to a position of employment with the Company after service in the uniformed services is not deemed to be absent from employment due to Qualified Military Service under this Section 2.32. Section 2.33 Social Security Benefits. Social Security Benefits means unreduced old age benefit payments or disability benefit payments (other than those payable because of military service) under the Social Security Act, as amended, or under any future legislation that amends, supersedes, supplements or incorporates the Social Security Act, to which the Participant or former Participant would be entitled upon proper application, assuming that the Pension paid under this Plan is his only income.

Spouse means an individual of the opposite sex or same sex to whom a Participant is legally married if their marriage was validly entered into in a state or foreign jurisdiction whose laws authorized the marriage, even if the couple lives in a state or foreign jurisdiction that does not recognize the validity of their marriage. This definition applies wherever the term spouse is used in the Plan, regardless of whether the term is capitalized. Cohabitants, domestic partners, life partners, and members of civil unions where such designation is not denominated as marriage are not recognized as Spouses. When deciding whether an individual qualifies as a Spouse, the determination will be based upon the laws of the State or jurisdiction in which the marriage was validly performed.

Notwithstanding the foregoing, if an Employee does not return to active Employment with the Company within two years following the beginning of a Maternity or Paternity Absence, the Employee shall not be deemed to have a Termination Date until the second anniversary of the first day of such absence. Section 2.37 USERRA.
