"As BIDS Trading continues to expand and evolve as a block trading platform, Vivian's expertise and guidance will play a central role," said Tim Mahoney, Chief Executive Officer of BIDS Trading. "Her experience working in the heart of Wall Street on a variety of market structure issues, coupled with her deep understanding of technology, intellectual property and financial regulation, will prove integral as we work toward achieving our goals."

Prior to joining BIDS Trading, Vivian served as Senior Vice President and Associate General Counsel at the NYSE Euronext. Appointed by the President (now CEO), Duncan Niederauer, she led the legal team that was responsible for modernizing NYSE market structure, supported the U.S. trading business lines and handled technology legal issues, strategic technology acquisitions and intellectual property protections.

Before the NYSE Euronext, Vivian spent more than twenty years as an industry-leading attorney, and Managing Director at Citi providing expertise in intellectual property and technology. Vivian also served as General Counsel for Citi's Global Transaction Services Division, a $4 billion business line that provides cash, trade, securities services and fund administration services for corporate clients in over 100 countries. Vivian graduated from Brooklyn Law School and Hunter College.

"BIDS Trading is developing very innovative trading technologies, and I am fortunate to have the opportunity to help the company to grow. The joint venture with the NYSE Euronext is a good example of our strategy in action," said Vivian. "I look forward to providing advice and guidance as the firm continues to deliver on its promise of offering dark liquidity in the block trading market for both the buy- and sell-side."

Volume on the BIDS Trading ATS has reached more than 5.8 billion shares* since its launch in 2007, with average daily volumes reaching 24.65 million shares* in July 2008.

The BIDS Trading ATS is accessible to both buy-side and sell-side firms that want to trade large blocks through continuous order matching and trade negotiation. Use of the BIDS ATS as a block trading service is not exclusive or subject to volume commitment and each participant may continue to use any ATS, ECN or exchange service that supports the trading needs of its customer base.

The BIDS Trading ATS allows traders to control their level of information disclosure. Market participants can choose to auto-execute their order or negotiate; they can set their minimum block size to help protect their order; and they can even filter out counterparties based on past trading behavior.
