5. In the case an optional programme is not fully subscribed within one year after the date at which it has taken effect in accordance with Article 3.2 the existing participants are bound to accept a new scale of contributions whereby the deficit is distributed pro rata, unless they agree unanimously on a different solution.
6. All contributions shall be made in European Currency Units (ECU) as defined by the European Communities. For MOP contributions may also be made in any convertible currency.
7. The methods of payment of the contributions, and the methods of updating the statistics for GNP, shall be determined in the Financial Rules.
