Corrective Contributions. If, with respect to any Plan Year, # an error is made in crediting Company Matching Contributions or earnings to a Participant’s Account, # an error is made with respect to the administration of the Participant’s Account or with respect to the investment of the assets of the Trust Fund, or # a market value adjustment is made upon termination of an investment, which error or market value adjustment results in an incorrect amount being credited to the Participant’s Account or to any amount being incorrectly deducted from a Participant’s Account, remedial action may be taken to correct such error or adjustment in accordance with this [Section 4.4(e)]. In such event, the Account balances of such affected Participants may be adjusted to the extent necessary to reflect the Account balances which would have existed had no such error or adjustment been made.

Any Account adjustments or additional contributions made under this [Section 4.4(e)] shall be made on a uniform and nondiscriminatory basis.
