(Adds background)

LONDON, April 6 (Reuters) – Deutsche Boerse (DB1Gn.DE: Quote, Profile, Research) has
no plans to raise its $10.2 billion bid for NYSE Euronext
(NYX.N: Quote, Profile, Research), confident the benefits of its deal will trump a higher
offer from rival U.S. exchanges, a source familiar with the deal
said.

Some shareholders and clients of the German exchange
operator had expected a possible bidding war with rivals Nasdaq
OMX (NDAQ.O: Quote, Profile, Research) and IntercontinentalExchange (ICE.N: Quote, Profile, Research) of the United
States.

But the source said on Wednesday: “There are no plans to
increase what Deutsche Boerse has already offered.”

Deutsche Boerse’s agreed all-share bid to create the world’s
largest exchange operator was topped last week by a $11.3
billion unsolicited cash and stock offer from Nasdaq
OMX/IntercontinentalExchange.

A source close to NYSE Euronext told Reuters in New York on
Wednesday a merger between NYSE and Nasdaq would be
strategically unattractive and face “insurmountable antitrust
problems”.

The board of the NYSE Euronext, which owns the venerable New
York Stock Exchange, plans to meet by April 14 to consider the
higher bid, another source familiar with the situation has said.

Deutsche Boerse, which is set to hold its next regular board
meeting on April 12, declined to comment.

But even without having to compete with an aggressive rival
bidder, Deutsche Boerse’s hopes of creating the world’s largest
financial exchange reliant on derivatives trading will still
need to be approved by increasingly nationalistic regulators.

The planned decision by Australia to reject Singapore
Exchange Ltd’s (SGXL.SI: Quote, Profile, Research) proposed $7.8 billion bid for
Australia’s ASX (ASX.AX: Quote, Profile, Research) on national interest grounds sends a
stark message to those hoping to score cross-border exchange
deals.

Bankers meeting at the Reuters Global Mergers and
Acquisitions Summit in London on Wednesday also noted that this
was likely to have ramifications for London Stock Exchange’s
(LSE.L: Quote, Profile, Research) planned 3.1 billion pound ($5.07 billion) merger with
Toronto exchange TMX GGroup (X.TO: Quote, Profile, Research).

“The noises coming out of Australia yesterday will
undoubtedly have a knock-on effect on the Canada/London deal,”
noted Caroline Silver, a managing director advising financial
services companies at independent investment bank Moelis.

Deutsche Boerse shares had stopped trading for the day in
Frankfurt before this story was made live.
