Upon payment by the Guarantor of any sums as provided above, all rights of the Guarantor against the Borrower arising as a result thereof by way of right of subrogation or otherwise shall in all respects be subordinated and junior in right of payment to the prior indefeasible payment in full of all the Obligations owed by the Borrower to the Holder.
