On February 5, 2008, NYSE Euronext held an investor conference call to discuss its 4th quarter and full year 2007 results, a recording of which is available on NYSE Euronext’s website. Below are two excerpts from the Q&A session of that call:

Q - Roger Freeman: Okay, and Duncan, lastly, can you give me an update on discussions that you've been having with the SEC around changes of the specialist market structure and specifically, as you look at buying the AMEX here does that give you any additional ability to drive an agenda since effectively you're going to be taking care of all of the equity exchange specialist operations, modernizing them?

A - Duncan Niederauer: Sure, the first part of your question, Roger is the dialogue continues very regularly and very actively. I think we're down to where we really just have two or three rules left. One has to do with their ability to hedge and really run their business as an integrated market maker which there's a follow-up meeting on tomorrow and I think we’ll be filing a rule on that front fairly soon about. Then the other two changes that we're contemplating making that will be concurrent with the next phase of the technology that rolls out that Larry was referencing earlier will be tied to what I would call the elimination of the look that the specialist has had pretty much forever, in exchange for probably slightly better treatment on the parity side. I think that's where we're going to head with that. In terms of the AMEX integration, I think that should over-simplify the landscape because it is the only other model that has what I would call close to a high-tech, high touch model, and I think we intend to bring that over here as possible. The ETF business - I don't think we’ll reinvent the wheel. I think you'll see that go to Arca, the listings business - I think you'll see us create just a slightly different approach on the listings side to account for all the different companies. And then as far as with their model with the specialist is, many of the specialists there are also specialists here, so we imagine that if the initial conversations are any indication, they will just consolidate their businesses and do it in one place instead of two and many of the ETF specialists are also LMM's on the NYSE Arca platform so we would imagine that they would just move over as well. So I think that's all kind of to be determined but that reflects the initial conversations we've had with some of the issuers and some of the market participants over at the AMEX.

Q - Niamh Alexander: Okay that's very helpful and I think we talked about it briefly before, but the listings, has the pitch changed now that you are more of a global and you have the cross listings? Do you find that the marketing pitch for the listings business is different now?


A - Duncan Niederauer: Yes, it's definitely different because remember if you look back at the NYSE company specifically, two years ago, it really only had one listing brand and you either qualified or you didn't, and now what we're trying to do, and you can see it in some of the success we had in '07 which was very broad in the U.S. and Europe and also in segments that we previously were comparably not as good in, I think we now have really quite a global listings offering for companies of all shapes and sizes and I think if we play our cards right and the AMEX deal gets approved I think we'll be able to extend that even further where we'll be able to protect the brand on one hand, and at the same time extend the brand, so that people have a lot of different choices of where they can list under that umbrella. As I've discussed with a few of you before, I do think that over time, companies will make a global listing decision and I think we'll see a reversal of this trend where large European multi-nationals delist for regulatory reasons, I think it will actually start going the other way.
