Principal of, premium, if any, and interest on, the Notes generally will be payable in euro.  In addition, the Operating Partnership will, subject to certain exceptions and limitations, pay additional amounts on the Notes as are necessary in order that the net payment of the principal of, premium, if any, and interest on, the Notes to a holder who is not a United States person, after withholding or deduction for, or on account of, any present or future taxes, duties, assessments or other governmental charges imposed or levied by the United States or a taxing authority of or in the United States will not be less than the amount provided in the Notes to be then due and payable.
The Operating Partnership may, at its option, redeem the Notes in whole at any time or in part from time to time on not less than 30 and not more than 60 days' prior written notice mailed to the holders of the Notes to be redeemed. The Notes will be redeemable at a price equal to the principal amount of such Notes being redeemed, plus accrued and unpaid interest to, but not including, the date of redemption and a "make-whole" premium calculated under the 30th Supplemental Indenture (unless the Notes are redeemed on or after July 2, 2020, in which case no "make-whole" premium will be payable).  The Operating Partnership may also, at its option, redeem all, but not less than all, of the Notes in the event of certain changes in, or amendments to, the tax laws of the United States (or any taxing authority of or in the United States). This redemption would be at a redemption price equal to the principal amount of such Notes being redeemed, plus accrued and unpaid interest to, but not including, the date of redemption.
