TNS Enters Polish Market; TNS Secures Three-Year Deal to Transmit Transactions Data for the Warsaw Stock Exchange.

RESTON, Va. -- Transaction Network Services (TNS) (NYSE:TNS) has expanded into Poland with the award of its first stock exchange contract in Central and Eastern Europe. TNS, one of the world's leading providers of secure data and voice network services to the global financial community, operates a network with 96 points of presence across North America, Europe and Asia-Pacific.

In a three-year contract, the Warsaw Stock Exchange has appointed TNS to transport data between the exchange and its members using TNS' Secure Trading Extranet.

The contract will allow traders, especially remote exchange members, to connect to the Warsaw Stock Exchange quickly and easily.

Wieslaw Rozlucki, President of the Warsaw Stock Exchange explains: "The TNS network provides a secure and reliable connection which offers benefits to all of our members. It can be accessed by members using various applications, irrespective of whether they are based on the Financial Information eXchange (FIX) protocol.

"With the installation of the TNS network, we are offering members flexibility to communicate quickly with any participating trading partner. It is our belief that this solution, among others, will make the Polish market an even more effective and liquid trading environment, foster further development of the Exchange itself and bring WSE new members and investors from Europe."

TNS' Secure Trading Extranet supports straight through processing between trading partners globally including banks, financial institutions and brokerage houses. To support the contract, TNS has established an operations base in Poland.

Rainer Zettl, managing director, TNS (Germany), said: "We are delighted to be working with the Warsaw Stock Exchange. This endorsement reflects the confidence of Central and Eastern Europe's largest public securities trading body in the TNS network.

"Increasingly customers are choosing TNS' Secure Trading Extranet to achieve counterpart connectivity. This is established within three days and once established gives lower communications costs, faster message delivery and reduced operational risk through fault tolerant and secure infrastructure."

Franz Bader, vice president, TNS (Central and Eastern Europe) added: "Poland is the first of many new territories in which we are establishing points-of-presence as we expand the TNS network. Central and Eastern Europe has seen a number of changes in recent years and we have set up a dedicated team to focus on this market. Our new points-of-presence combined with our secure network and operating base in Poland will act as a springboard from which to grow business within Central and Eastern Europe and with other exchanges on the Continent."

As part of TNS' expansion into Central and Eastern Europe, it has established two diverse points-of-presence in Warsaw which will provide fully fault tolerant and redundant connectivity for TNS' clients, including the Warsaw Stock Exchange. These hubs will allow customers to link to TNS' Secure Trading Extranet and route transactions across the TNS network.

TNS' Secure Trading Extranet is one of the world's largest financial communities of interest with more than 1000 connected end-points. It enables participants to submit indications of interest (IOIs), route orders, execute trades, access trading applications, exchanges and ECNs, and perform other FIX and non FIX-based transactions.
