1.    Interest. The Company promises to pay interest on the principal amount of this Security at [1.950%] [2.950%] [4.300%] [5.875%] per annum from March 12, 2012 until maturity. The Company will pay interest semiannually on [March 5 and September 5] [May 1 and November 1] [April 1 and October 1] [May 1 and November 1] of each year (each an “Interest Payment Date”), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid, or, if no interest has been paid, from [September 5, 2012] [November 1, 2012] [October 1, 2012] [November 1, 2012]; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof (each, a “Record Date”) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be [March 5, 2013] [May 1, 2013] [April 1, 2013] [May  1, 2013]. The Company shall pay interest on overdue principal and premium (if any) from time to time at a rate equal to the interest rate then in effect; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.
