The Employer by which the Participant was last employed prior to his payment date under the Plan shall process and pay all Excess Retirement Benefits hereunder to or on behalf of such Participant, but such Employer’s liability shall be limited to its proportionate share of such amount, as hereinafter provided. If the Excess Retirement Benefits payable to or on behalf of a Participant are based on the Participant’s employment with more than one Employer, the liability for such Benefits shall be shared by all such Employers (by reimbursement to the Employer making such payment) as may be agreed to among them in good faith (taking into consideration the Participant’s service and Compensation paid by each such Employer) and as will permit the deduction (for purposes of federal income tax) by each such Employer of its portion of the payments made and to be made hereunder. Expenses of administering the Plan shall be paid by the Employers, as directed by the Company.
