All Holders of Notes (each, a “Holder” and collectively, “Holders”) whose Notes are accepted in an Offer will receive a cash payment equal to accrued and unpaid interest on such Notes to, but not including, the relevant Settlement Date (as defined in the Offer to Purchase) (the “Accrued Coupon Payment”) in addition to their Total Consideration or Tender Consideration, as applicable. For the avoidance of doubt, interest will cease to accrue on the Settlement Date for all Notes accepted in the Offers.
