The following are portions of a transcript of an investor presentation held by Equinix, Inc. on December 2, 2009:

Mike Buchanan—NASDAQ OMX—Managing Director

Good afternoon. My name is [Mike Buchanan], I am the managing director for NASDAQ OMX. Our next presentation for the day is Equinix.

****

Stephen Smith—Equinix Inc.—President and CEO

Good afternoon, everybody. I will spend probably 15 minutes with some prepared remarks and then we will take whatever questions that you might have generated from the content.

****

I’m going to talk about four topics today. A little snapshot of the business for people that are not that familiar with it. A snapshot of our financials. We just announced an acquisition in the US market with a company called Switch & Data. And then we will wrap with some Q&A.

****

Because of the Switch & Data acquisition we did not provide guidance for 2010. We’ll probably do that in our next quarter.

****

Switch & Data. So we announced on October 21 the acquisition of Switch & Data for $689 million of equity value at the time of signing on October 20. It is an 80/20 split. 80% stock, 20% cash. We expect to close this sometime mid to late first quarter. It is going through the regulatory and Department of Justice review as we speak.

The rationale for the deal was pretty straightforward. This is a US-based decision. It is driven by scale, access to capital, cost of capital, all the things that are driven underneath a capital-intensive business that are going to bring us into new markets. We were in six markets in the US. We will pick up an additional 16 markets.

So this is all about covering the US market in a deeper fashion. If you believe that latency is going to matter and you believe that infrastructure is going to continue to be deployed beyond those six key markets, we did convince ourselves this was a key part of this deal.

They will bring us capacity in the current six markets that we are in today. The interconnection, they’re are very focused. It is a very similar business model to the Equinix business model. They are very network dense. They are very network focused. So from an integration standpoint this will be fairly straightforward and there are synergies here.

On the cost side, we’ve estimated $20 million of synergies who keep an eye on the rest of the leadership team, believe that there will also be revenue synergies. We would line up across almost any line in the P&L, we think we are going to be able to address synergies here.

So the Company looks exactly like Equinix — smaller, more cities, but same kind of model, same kind of data center set up. So we are pretty excited about the opportunity to get after that.

And then financially, we will pick up some NOLs here so there will be a financial benefit. Probably will help extend the (inaudible) 2011, 2012 in terms of becoming a taxpaying entity.

And then there will be some refinancing efficiencies, and capital efficiencies as we put these two businesses together.

Visually if you look at it, I mentioned a couple of these numbers. If you combine them tomorrow once this thing closes, at the end of the first quarter, we will look like a 34 market, 79 data center, 6 — over 6 million gross square feet of space around the world.

Again this is a US-focused asset and you can see the dots on the map in the bottom of this. It will now put us in nine of the top 10 markets in the US. And again, that is very important to us as we study the future trends of the business more and more of this infrastructure, servers, storage equipment and networking gear is getting deployed closer to the edge of the network. The edge of the network is extending. Latency matters for the applications are running on this infrastructure.

So having a broader footprint in the US has been very, very critical for this decision.

The one market that is not listed here that — the 10th market is Houston. So Houston in the US is the 10th largest Internet market. And it was not in their portfolio.

And then if you combine on a pro forma basis, we took the third quarter actuals. Just to give you a view, as I’ve said, we have not combined these businesses yet in terms of the 2010 snapshot. We won’t be able to do that until we close.

But if you just look at taking the third quarter on the top part of this chart, the balance sheet, you get a sense this is almost a $4 billion asset company now when we combine Switch & Data with Equinix and the debt, the net debt ratio is still around 2.2, 2.3. So we are still within that range where we want to run our net debt adjusted EBITDA. And then if you look at the bottom of this, it gives you a sense, if you take the third quarter actuals for both companies and combine them, you start to see the scale of this business on an LQA basis.

So we are pretty excited about this. This really gives us a chance in the US market to really be able to satisfy almost any requirement that we would see anywhere in the US from a city standpoint. From a metro standpoint.
