Administration 2.1 Administrator - The Plan shall be administered by the pension and benefits department of the Company. Article III. Benefits 3.1 Qualified Plan Pension - At the time of retirement, all Participants shall have their pensions calculated under the provisions of the Qualified Plan, taking into account the Participant's age and years of service at retirement, the retirement option selected by Participant, and such other factors set forth in the Qualified Plan or any provision of federal, state, or local law, as would affect the calculation of Participant's benefit under the Qualified Plan. This is the amount of the pension payments payable to Participant or Participant's Beneficiary under the Qualified Plan. 3.2 Benefits Under the Plan a.

In any instance where the pension payable to the Participant or the Participant's Beneficiary under the Qualified Plan is reduced because of any provision of federal, state, or local law from the amount which would otherwise have been payable under the Qualified Plan, the Participant or Participant's Beneficiary shall be entitled to receive a pension under the Plan in an amount which, when added to the amount the Participant or Participant's Beneficiary is entitled to receive under the Qualified Plan, results in a total amount of pension payments payable to Participant or Participant's Beneficiary from the Plan plus the Qualified Plan equal to the amount which Participant or Participant's Beneficiary would have been entitled to receive from the Qualified Plan had there been no reduction as a result of the provisions of federal state, or local law. 3.3 Payment of Plan Benefits - Benefits shall be payable to Participants under the terms of either option a or option b as set forth in this section. a.
