LANDLORDS EXPENSES, LEGAL PROCEEDING COSTS AND LATE CHARGES
22.1. Landlords Costs.
Tenant shall pay to Landlord an amount equal to the reasonable costs that Landlord incurs in instituting or prosecuting any legal proceeding against Tenant (or any other Person claiming by, through or under Tenant) to the extent that such legal proceeding derives from the occurrence of an Event of Default, together with interest thereon calculated at the Applicable Rate from the date that Landlord incurs such costs, within thirty (30) days after Landlord gives to Tenant an invoice therefor (it being understood that (x) Landlord shall have the right to collect such amount from Tenant as additional rent to the extent that Landlord incurs such costs during the Term and as damages to the extent that Landlord incurs such costs after the Expiration Date, and (y) the amount that Landlord has the right to collect from Tenant under this Section 0 shall be adjusted appropriately to reflect the extent to which Landlord is successful in such legal proceeding).
22.2. Legal Proceeding Costs.
If Landlord or Tenant, as the case may be, institutes or prosecutes any legal proceeding against the other arising out of this Lease, then the losing party in any such legal proceeding shall pay to the prevailing party an amount equal to the reasonable actual out-of-pocket costs that the prevailing party incurred in instituting or prosecuting such legal proceeding, together with interest thereon calculated at the Applicable Rate from the date that the prevailing party incurred such costs, within thirty (30) days after the prevailing party gives to the non-prevailing party an invoice therefore. If the determination in any such legal proceeding is that the prevailing party was partially liable, then the non-prevailing party shall pay to the prevailing party the percentage of the aforesaid costs equal to the percentage by which the prevailing party was successful (so that if, for example, the prevailing party was determined in any such proceeding to be twenty percent (20%) liable, then the non-prevailing party would pay the prevailing party only eighty percent (80%) of the prevailing partys costs to institute or prosecute such legal proceeding).
22.3. Interest on Late Payments.
If Tenant fails to pay any item of Rental on or prior to the third (3rd) day following the date that such payment is due, then Tenant shall pay to Landlord, in addition to such item of Rental, as a late charge and as additional rent, an amount equal to interest at the Applicable Rate on the amount unpaid, computed from the date such payment was due to and including the date of payment. Nothing contained in this Section 22.3 limits Landlords rights and remedies, by operation of law or otherwise, after the occurrence of an Event of Default.
