We're getting a lot of extensions.

This is definitely something special. The national spotlight is on Houston, and we're happy to host guests of this caliber.

They were barking this morning. There are dogs throughout our lobby kind of hanging out with their owners. It's a zoo here.

We're not into endless extensions,

We believe that the extensions of our existing agreements and the two new collaborations that we entered into during 2005 provide further validation of our technology and commercial potential. Our goal is to continue to leverage our discovery and development capabilities by establishing additional collaborations with market leading companies seeking to create a competitive advantage for their products.

We worked very hard to make extensions very simple.
