The Special Election would be effective only in the event of a Change of Control preceding the Participant's Termination of Service. Any such election must be completed on the form provided by, and submitted to, the Administrative Committee or its designee before the shareholders of the Company vote on any proposed action which, if completed, would constitute a Change of Control. The Special Election is subject to the following limitations and conditions and the Participant's Termination of Service: A. The Participant's earliest payment start date shall be the first January, but not earlier than 12 months, following the date of the Change of Control; B. The Participant's Retirement Distribution payment(s) must be made or begin to be made no later than the fifth January following a Change of Control; C. The Participant may select a Retirement Distribution to be paid in one of the following ways: (1) single lump sum payment; (2) annual installment(s) over one, two or three years (only available if a Lump Sum Payment is elected); and / or (3) monthly installments over five, ten or fifteen years. D. The Retirement Distribution payments must be completed within 20 years following the date of the Change of Control. 3. Article III, Section 3.1 is amended by adding a new Section 3.1(c) to read as follows: (c) INTEREST RATE AFTER A CHANGE OF CONTROL. Notwithstanding any other provisions of this Plan, after a Change of Control, Interest Rate shall mean the greatest of (1) 125% of the 120-month rolling average of the 10-year U.S. Treasury Note rate for the period ending the prior June 30, effective for the Plan Year commencing thereafter, determined in a manner consistent with past practice; or (2) the Citibank Base Rate; or (3) the rate of interest credited under a comparable plan maintained in the United States for senior executives of BP Amoco p.l.c. and Atlantic Richfield Company (or upon a subsequent Change of Control, the acquiring company). The provision of clauses (1), (2), and (3) shall apply for 10 complete Plan Years, with the first year commencing the January 1 after the Change of Control. For the 11/th/ through 20/th/ years after a Change of Control, the Interest Rate shall be no less than the greater of (2) or (3) above. If a Change of Control occurs within any of the above time periods, the time periods would restart commencing on January 1 after any such Change of Control. As used above, the term "Citibank Base Rate" means the rate of interest announced from time to time by Citibank, N.A. or its successor as its base rate of interest charged to its customers. If Citibank, N.A. is not in existence then the Special Plan Administrator shall substitute the base rate of another major money center bank located in the United States. If a Participant fails to make a Special Election as described above, or has a Termination of Service before a Change of Control occurs, payment of the Participant's Retirement Distribution will be made in accordance with the Participant's previous election. 4. Article IV, Section 9.1 of the Plan shall be amended in its entirety to read as follows: 9.1 Upon a Change of Control, the interests of all the remaining Participants shall continue and provisions shall be made in connection with such transaction for the continuance of the Plan and the assumption of the obligations of the Company under the Plan by the Company's successor(s) in interest.
