First Electronic Tri-Party Client Interest Rate Swap Trade Executed

Reduces Trade Processing Time to Less than Thirty Minutes from Execution to Clearing

LONDON, September 30, 2010 - Tradeweb, a leading global provider of fixed income and derivatives
markets, today announced the execution of the first ever, fully electronic
tri-party interest rate swap trade, involving client, dealer, clearing member
and clearing house. The transaction was executed on the Tradeweb platform
between MPS Capital Services (the investment banking arm of Banca Monte dei
Paschi di Siena, the oldest bank in the world) and Credit Suisse. The trade
was affirmed by both parties, with Barclays Capital being the clearing
member. The trade was cleared by LCH.Clearnet, with the total transaction
taking less than 30 minutes to complete.

MPS is leading other clients in the adoption of central clearing,
expected to become the industry standard in Europe and in the United States
following pending regulation. The bank recently began backloading $200
billion of interest rate swap trades through LCH.Clearnet, in preparation for
streamlining the execution process. MPS has been executing interest rate
swaps on Tradeweb for more than four years.

"MPS has blazed a trail for the marketplace," said Enrico Bruni, Managing
Director and Head of European Rates at Tradeweb. "We anticipate that a broad
range of clients will now move quickly to adopt the central clearing model,
which along with electronic trading, represents the inevitable future of the
industry."

"We are very happy to have been involved in this landmark transaction,"
said Matteo Bertotti, Head of Fixed Income Derivatives at MPS Capital
Services. "More efficient markets will benefit all market participants in the
long run; this represents a blueprint for how the workflow will look in the
months and years ahead for many derivatives trades."

"This is an important step toward broader automation in the global
derivatives markets," said Shane O'Cuinn, Head of European Swaps Trading at
Credit Suisse. "As part of our ongoing commitment to delivering
market-leading solutions to our clients, we are pleased to be the dealer for
the first fully-electronic tri-party swap trade."

"The trade executed by MPS on Tradeweb is a testimony to the progress
made to improve trade processing in clearing OTC derivatives and to embrace
the principles at the core of regulatory reforms," said Ray Kahn, Head of OTC
Derivatives Clearing at Barclays Capital. "As an extension of our ongoing
agreement to clear interest rate swaps on behalf of MPS, we were pleased to
once again be at the forefront of developments in OTC derivatives clearing."

"We would like to congratulate Tradeweb and their partner banks for
taking another significant step in the adoption of automation in client
clearing. Clearing trades intra-day through SwapClear helps to reduce
systemic risk and our leading risk management solutions continue to benefit
both clients and clearing members alike," said Michael Davie, CEO of the
SwapClear service at LCH.Clearnet.
