Thanks, Dale. As I hope is quite apparent, this has been a very busy and productive quarter for us. We are advancing the technology on many fronts, internally in the therapeutic arena and through our partnerships in plant agriculture, research reagents, transgenic animal models and cell engineering. Our collaboration with Dow AgroSciences is now in its commercial phase. As I mentioned earlier, DAS hosted a very informative press conference, and I encourage you to watch the webcast, which is archived on our website, and hear directly from the DAS management of their enthusiasm for our ZFP technology and their plans to develop EXZACT Precision Traits, both internally and under sublicenses. Our partner, Sigma-Aldrich, now has a website for researchers to request ZFP reagents and plan a full-blown launch of the technology this fall. More recently, we signed an agreement with Hoffmann-La Roche to provide them with non-exclusive rights for the use of ZFN to generate transgenic animals, modified in a specific gene in a specific species. Roche has an option to purchase an exclusive commercial license to use these animals in the production of therapeutic and diagnostic products. While the payments in the initial research phase of the agreements are modest, if Roche elects to take out a commercial license, we will receive a license fee, additional payments upon the achievement of certain clinical development events and downstream commercial payments. Remember, this is a single gene in a single species. We believe that our ZFN technology will make the efficient generation of transgenics in any gene in any species a reality, opening the way for a wider range of animal models for human disease research and drug development and significant potential commercial value. In conclusion, the first half of 2008 has seen substantive and exciting progress on the research, clinical and business fronts, and our aim is to continue in the same vein for the foreseeable future. Our principal deliverables for the remainder of the year will be the presentation of Phase 2 data from our SB-509 clinical program, both SB-509-601 and 701; initiation of a Phase 2 trial with SB-509 in ALS; as well as the filing of INDs for our first two ZFN-based therapeutics. We also expect continued progress in non-therapeutic areas, the official launch of the ZFP products by Sigma-Aldrich and additional commercial interest in our ZFP technology for cell line engineering and transgenic animals. We will, as always, continue to carefully manage our expenses. Finally, before we open up the call for your questions, we will be providing additional updates on our progress at the Bank of Montreal Focus on Healthcare Conference and the Canaccord Adams Global Growth Conference in August and the UBS Global Life Sciences Conference in September. We will make all of these presentations available on the Investor section of our website. This completes our prepared comments. So, we'd now like to open the call for your questions.
