The NYSE today will introduce NYSE Order Imbalances, a rich, new data product that will increase the transparency of the NYSE's daily open and close, the two most critical periods of the trading day.

Reflecting our ongoing commitment to customers of the New York Stock Exchange, today we filed with the Securities and Exchange Commission a package of new rules and amendments to existing rules that will further enhance the performance, quality and competitiveness of the NYSE.

The NYSE anticipates limited trading in UBS AG Rights (Expiring June 10, 2008) Symbol: UBS RT - today, Monday, June 9, 2008, trading as Cash Only. There will be four auctions: the first at approximately 10 am ET, followed by auctions at approximately noon ET and 2 pm ET, and a final transaction at approximately 4 pm ET. Update messages (online at traderupdates.nyse.com and via NYSE System Status) will confirm these times, and these transactions will follow routine price indication procedures and indication time intervals.

NYSE Member Firms routing orders via CMS or CCG for NYSE Arca primary securities, ETFs, and NYSE listed Subpenny halted securities will be routed directly to NYSE Arca. This routing rule will also apply to orders entered with NYSE booth “Agency” designations. Booth directed orders will only be accepted into NYSE BBSS for stocks actively trading at the NYSE.

CMS Product Brief

In an effort to provide firms with updated and expanded business recovery capabilities, NYSE Euronext will retire our Contingency Trading Floor and instead will request, that in the event of a BCP scenario, firms redirect their order flow to the NYSE Arca trading platform. All firms that are currently connected directly to NYSE Arca or have access through a current NYSE Arca ETP (Electronic Trading Permit) holder will continue to have access to the NYSE Arca platform.

The implementation of a new Common Customer Gateway (CCG) release will begin rollout this Friday, May 30, 2008 and go live on Wednesday, June 4, 2008.

Beginning on Friday, May 9, 2008 the New York Stock Exchange will extend the DOT Reserve Order type from the current 100 pilot securities to all NYSE Listed Securities. Requiring a minimum posting of 100 shares and offering the ability to enter flexible replenishment amounts, the new DOT Reserve order will give clients additional flexibility in managing their NYSE systemic order flow and accessing the Exchange's unparalleled liquidity pool. The planned floor wide expansion will allow this useful order flow management tool to now be used for all NYSE Listed names.

Beginning Monday, May 5, the Common Message Switch (CMS) will open for NYSE order entry at 7:30 a.m. ET, 30 minutes earlier each trading day.

This additional pre-Opening access to NYSE trading systems has traditionally been available only on Expirations, and will now be extended to all trading sessions, allowing more time for customers to verify connectivity and prepare for the trading day.

The New York Stock Exchange is moving forward with Phase 1 of the DOT Reserve Pilot.
