Payments to the Agent
(a) On each date on which an Obligor or a Lender is required to make a payment under a Finance Document, that Obligor or Lender shall make the same available to the Agent (unless a contrary indication appears in a Finance Document) for value on the due date at the time and in such funds specified by the Agent as being customary at the time for settlement of transactions in the relevant currency in the place of payment. A payment made by an Obligor to the Agent which relates to moneys owed to a Finance Party shall be deemed to be received by such Finance Party once made to the Agent.
(b) Payment shall be made to such account in the principal financial centre of the country of that currency (or, in relation to euro, in a principal financial centre in a Participating Member State or London) with such bank as the Agent specifies.
