NEW YORK, Oct. 2, 2007 (PRIME NEWSWIRE) – The Nasdaq Stock Market, Inc. (NASDAQ(r)) (Nasdaq:NDAQ), today announced it has entered into a definitive agreement to acquire the Boston Stock Exchange (BSE), including the holding company (BSE Group), the Boston Equities Exchange (BEX), the Boston Stock Exchange Clearing Corporation (BSECC), and BOX Regulation (BOXR). Along with these businesses, NASDAQ will acquire an SRO (Self-Regulatory Organization) license for trading both equities and options. NASDAQ’s acquisition of the BSE Group is valued at approximately $61 million.

NASDAQ will not acquire an interest in the Boston Options Exchange (BOX) from the BSE. However, a regulatory framework for the BOX market will remain in place. NASDAQ, through BOXR, will operate the regulatory services provider to the BOX, which is an options trading facility of the BSE. NASDAQ and BOX are discussing a plan regarding the future regulatory structure for BOX.

Bob Greifeld, President and Chief Executive Officer of NASDAQ, said, “NASDAQ is very focused on meeting the needs of its customers. This transaction provides added liquidity, new trading choices and an enhanced competitive market environment. NASDAQ’s acquisition of the BSE will expand NASDAQ’s execution offerings, and deliver user and investor benefits consistent with our Brut and INET acquisitions.” Greifeld added, “We believe a second exchange license in both equities, and in the future options, will provide market structure flexibility as we continue to deliver on our mission of being the number one trading platform in the transactions business.”

Upon approval of the transaction, NASDAQ will have the ability to offer a second quote within the U.S. equities marketplace. NASDAQ anticipates operating the BSE using its INET trading system.

Additionally, subject to SEC approval, NASDAQ anticipates utilization of the BSE Clearing Corporation.

NASDAQ Executive Vice President of Transaction Services, Chris Concannon commented, “This deal will allow our customers to better execute their trading strategies. From critical trading functionality, to crossing products, and risk management offerings,

NASDAQ’s second quote in NASDAQ, NYSE and AMEX-listed securities will arm our diverse customer base with more choices and competitive pricing options. Additionally, we are optimistic that the clearing business will provide valuable benefits for both NASDAQ and our customers over time.”

The transaction is subject to SEC approval and approval by BSE members. NASDAQ & BSE’s board of directors have approved the transaction, which is expected to close by early first quarter 2008.
