To share in the allocation of any retirement contribution made by a Schedule C.1 Employer for a Plan Year, Eligible Employees described above must be credited with at least 1,000 Hours of Service (prorated for the Plan Year in which the retirement contribution feature becomes effective) in the Plan Year and must not be covered by a collectively bargained unit to which the retirement contribution feature has not been extended. However, if the Participant’s failure to be credited with 1,000 Hours of Service in that Plan Year is due to the Participant’s (i) Disability, (ii) death, or (iii) termination of employment on or after attaining Normal Retirement Age during such Plan Year (provided that the Participant is not terminated for cause), such Participant shall nevertheless be entitled to share in the allocation of the retirement contributions for such Plan Year. A Participant who is not a Highly Compensated Employee who has met the above eligibility requirements as of




June 30 each Plan Year shall receive a pro rata allocation mid-year based on Compensation paid through June 30. The final annual allocation shall be reduced by any such mid-year allocation. Participants who meet the requirements of this Section C.1-2 are referred to herein as “Schedule C.1 Participants.” Eligible Employees of Capital Electric Line Builders, Inc. will receive an annual allocation in the initial year of adoption.


The Plan is amended effective as of the date specifically set forth above and executed by a duly authorized individual on the date set forth below.
