(section 2.3 Eurex Trading Conditions)

(1) Orders and quotes relating to the same contract or to a system-supported combination of contracts may, in case they could immediately be executed against each other, neither be entered knowingly by an Exchange Participant (a cross trade) nor pursuant to a prior understanding by two different Exchange Participants (a prearranged trade), unless the conditions according to paragraph 3 have been fulfilled. The same shall apply for the entry of orders as part of a quote.

(2) An Exchange Participant may submit a description of his internal and external links to the EDP system of the Eurex Exchanges to the Market Surveillance Office of Eurex Germany or to the Surveillance and Enforcement Office of Eurex Zurich, with a view to a decision on whether the Exchange Participant acted knowingly within the meaning of paragraph 1. The details of the specifications of the description of the IT linkage pursuant to sentence 1 shall be determined by the Surveillance Offices of Eurex Germany and Eurex Zurich in agreement with the Boards of Management of the Eurex Exchanges. The specifications shall be subject to publication. Disclosure of said specifications to one of the two Surveillance Offices named above shall be deemed to be disclosure to both Eurex Surveillance Offices.

(3) A cross trade or a pre-arranged trade is admissible if a participant in a cross-trade or a pre-arranged trade, prior to entering his order or quote, enters a cross request equivalent to the number of contracts of the order. The order or quote giving rise to the cross trade or pre-arranged trade must be entered one second at the earliest and 61 seconds at the latest with regard to Money Market Futures contracts, Fixed Income Futures contracts, Options on Money Market Futures contracts and options on Fixed Income Futures contracts, respectively 31 seconds at the latest with regard to all other futures and option contracts after having entered the cross request. The purchasing Exchange Participant shall bear the responsibility for compliance with the content of the cross request entry.

(4) Paragraphs 1 and 3 shall not apply to transactions consummated during the netting process in the opening period (subsection 1.3 paragraph 2) or during the closing auction (subsection 1.3 paragraph (3)).

(5) Paragraph 1 shall apply mutatis mutandis to other behaviour constituting evasion of this regulation.
