Section 5.02 COMPENSATION TAKEN INTO ACCOUNT IN DETERMINING CONTRIBUTIONS of Basic Plan Document No. 02 is amended in its entirety to read as follows: COMPENSATION TAKEN INTO ACCOUNT IN DETERMINING CONTRIBUTIONS. In determining the amount or allocation of any contribution that is based on a percentage or amount of Compensation, only Compensation paid to a Participant for services rendered to the Employer or a Participating Employer while employed as an Eligible Employee shall be taken into account. Except as otherwise specifically provided in this Article 5, for purposes of determining the amount and allocation of contributions under this Article 5, Compensation means wages within the meaning of Code Section 3401(a) and all other payments of compensation that are actually paid or made available in gross income during the Plan Year to an Employee by the Employer (in the course of the Employer's trade or business) for which the Employer is required to furnish the Employee a written statement (Form W02) under Code Section 6041(d), Section 6051(a)(3) and Section 6052 excluding reimbursements or other expense allowances, fringe benefits (cash or non-cash), moving expenses, deferred compensation (other than deferrals referenced below), welfare benefits and Compensation paid during the determination period while not a Participant in the component of the Plan for which the definition is being used. Compensation must be determined without regard to any rules under Code Section 3401(a) that limit the remuneration included in wages based on the nature or location of the employment or the services performed (such as the exception for agricultural labor in Code Section 3401(a)(2). Compensation will include amounts not currently includable in gross income by reason of Code Section 125, Section 132(f)(4), Section 402(e)(3), Section 402(h), Section 457(b) or Section 403(b). Compensation for Plan purposes will not exceed the lesser of $200,000 or the adjusted limit under Code Section 401(a)(17). A cost of living adjustment in effect for a calendar year applies to any period not exceeding 12 months over which Compensation is determined (determination period) beginning in such calendar year. If a determination period is less than 12 months, the dollar limitation will be multiplied by a fraction, the numerator of which is the number of months in the determination period, and the denominator of which is 12. Compensation of an Owner-Employee or a Self-Employed Individual will equal Earned Income up to the above limitation. 16.
