Excerpt 1:

Robert Greifeld, Nasdaq President and Chief Executive Officer:

Good morning everyone and thank you for taking the time to join us this morning. We do appreciate your interest in NASDAQ and for taking the time to examine the two issues before us today.

Those issues are the issuance of additional shares of NASDAQ common stock in connection with our transactions with OMX and Borse Dubai and to amend our certificate of incorporation in order to change our name to the The NASDAQ OMX Group.

The OMX Borse Dubai transactions will be transformational for NASDAQ. Today’s vote is an important part of our journey towards becoming the leading global exchange and technology company. At the completion of this transaction our exchange will have a new footprint and it will truly be a unique footprint.

Our business will span the U.S., Europe and the Middle East, Africa as well as other emerging markets that are strategic to our business. Our products and services will encompass trading, listings and technology that will support other exchanges around the globe.

We have a clear mission and a clear path as we redefine NASDAQ’s business and our leadership role within the context of rapidly evolving global capital markets. I thank you again for your time and support as we move towards bringing this important transaction to fruition. Thank you.
