Thank you, Hank and good afternoon everyone. As you saw on our press release, Gen-Probe had a solid fourth quarter financial performance. Product sales grew 8%, compared to the same period in 2006, despite some uneven shipment timing that cost us about $3 million of blood screening sales. Total revenues increased 9% and earnings per share increased 16% on a GAAP basis, again exceeding our expectations. Hank already discussed product sales, so let me start with collaborative research revenue, which was $5.4 million for the fourth quarter, up significantly from $1.2 million a year ago. This increase came mainly from three sources. First, we earned $2.7 million of milestones and research reimbursement from 3M under our food testing collaboration. And milestone payments resulted from our successfully developing prototype assays for Campylobacter, Salmonella and Listeria, three common food contaminants. Although this collaboration has ended, Gen-Probe remains full ownership of these three assays and their commercial rights. We remain optimistic about our long-term potential in molecular food testing, especially given the resources that have been dedicated to food safety at the FDA and USDA. Second, we received research funding from 3M under our separate collaboration for healthcare associated infections, as well as our first milestone for achieving technical feasibility. And third, we benefited from the last piece of funding under our Department of Defense grant for prostrate cancer research. I would caution you that our strong fourth quarter performance on this line should not be taken as a run rate going forward, as neither the 3M Food payments nor the Department of Defense grant will continue in 2008. Royalty and license revenue was $1.1 million in the fourth quarter, down significantly from the $4.4 million in the prior year period. This decrease resulted primarily from the absence of license revenue from bioMérieux. As you might recall, we announced our licensing agreement with bioMérieux in 2004, and recorded the last installment of associated revenue in the fourth quarter of 2006. As we look ahead to 2008, our fourth quarter performance probably is a good indicator for royalty and license revenue. Gross margin on product sales was 69.2% in the fourth quarter, up from 67.6% in the prior year period. This increase was due primarily to the benefits of full commercial pricing of our West Nile virus assay, TIGRIS system, and to a favorable product mix, primarily reduced sales of lower margin instrumentation. Although instrument sales were down overall compared to the prior year period, sales of TIGRIS instruments to Novartis were good, totaling about $3.4 million and portending future growth in assay revenue. Research and development expenses for the fourth quarter were $24.3 million, up 17% compared to a year ago. This increase, which was expected, resulted primarily from the ramp up of our major development projects. These include the ULTRIO post-marketing yield studies in the United States, our APTIMA HPV program, our Panther project and our MRSA program with 3M. Marketing and sales expenses in the fourth quarter were $11.3 million, an increase of 18% compared to the prior year period. As we forecasted in our last call, marketing and sales costs increased primarily based on European market development costs associated with our HPV and PCA3 assays. General and administrative expenses were $12.3 million in the fourth quarter, up 14% versus a year ago. This increase was due primarily to compensation related costs as well as several miscellaneous expenses including legal fees. In terms of tax rate, there was a lot going on in the fourth quarter, all of it favorable to the bottom line. Our tax rate for the quarter was only 22%, as a result of three factors: The completion of an audit of our 2003 and 2004 California state income tax returns, true-ups associated with the completion filing of the company's 2006 California income tax return and adjustments to our effective tax rate for additional research and development credits earned in 2007. You might recall that in our last call, we guided to a fourth quarter tax rate of approximately 30%. But, we actually saw income tax reductions in excess of that. Specifically, of the $3.8 million in tax benefits we realized in the fourth quarter, about $2 million of it was not quantified in our previous financial guidance, leading to approximately $0.04 of additional earnings per share. All this nets out the fourth quarter earnings per share of $0.37, 16% higher than the prior year period; nearly double our 9% total revenue growth and ahead of expectations. Now, I'm returning to our 2008 guidance. We expect this year to be characterized by double-digit top line growth, appropriate R&D investment that supports, both near term product sales and long-term innovation, healthy net profit margins in excess of 20% on a GAAP basis, and pre-tax earnings growth at the fastest rate since 2004. Like in 2007, we expect low double-digit product sales growth to be driven by continued market share gains of the APTIMA Combo 2 assay, our commercial pricing of our West Nile virus assay on the TIGRIS system and by continued international expansion of PROCLEIX ULTRIO assay. In terms of instrument revenue, we had a very good year in 2007 and therefore, expect these sales to decline in 2008, based in part on the absence of TIGRIS spare part sales to Novartis. As you might recall, approximately $3 million of spare part sales passed through our income statement in 2007. As Hank said, we are not including in our 2008 guidance any incremental U.S. revenue from early adoption of the PROCLEIX ULTRIO assay in United States. As soon we file in March, we believe we could get approval in the third quarter based on the FDA standard review time. However, since it would take Novartis a couple of months to negotiate commercial contracts and since we record donation revenue two months after our partner does, it's unlikely we will see any material revenue before year-end. We could see some upside here based on an early approval, but a lot has to happen before we would be comfortable including this in our guidance. Overall, we expect total revenues of $443 million to $453 million in 2008, including low double-digit product sales growth. Product sales are expected to increase gradually on a sequential basis over the course of the year. In terms of collaborative research revenues, let me remind you that two major sources of 2007 revenue will not recur in 2008, namely, research reimbursement and milestones associated with our former food testing collaboration and our Department of Defense grant related to our prostate cancer program. However, non-product revenues are expected to benefit from two significant one-time items. First, MilliPROBE royalty and license revenue of about $16 million in the first quarter, representing Bayer's third and final payment under the settlement of our successful patent infringement lawsuit against them. And second, as Hank discussed, we expect to earn a $10 million milestone from Novartis potentially in the third quarter, based on the full approval of the PROCLEIX ULTRIO assay on the TIGRIS system in the United States. As an aside, we expect to record this ULTRIO milestone in collaborative research revenues rather than royalty and license revenue, which I believe is where most of you have modeled it. Apart from these two one-time items, we expect both collaborative research revenues and royalty and license revenues to be relatively flat in each of the four quarters of 2008. Now, let's turn to guidance for the expense lines. We expect gross margin on product sales to improve to between 68% and 70%. On the positive side, we expect the gross margin percentage to benefit from continued growth of our APTIMA STD franchise and from commercial pricing of our West Nile virus assay on the TIGRIS system. We also expect reduced sales of lower margin instrumentation in 2008, which reduces our top line relative to 2007, but helps our margin percentage. These benefits will be offset somewhat on a percentage basis, by the continued growth of the PROCLEIX ULTRIO assay outside the United States, including in many emerging markets, where pricing is less robust and pool sizes are smaller. I should point out however that the sales still provide incremental margin dollars, even when the margin percentage is lower, than what we might see in the United States or elsewhere. We expect R&D expenses to range from 23% to 24% of total revenues, down just slightly from 2007 levels on a percentage basis. As Hank discussed, we expect the big ticket items in 2008 to include inline product support, which will represent about 25% of our direct costs, mainly for the ULTRIO post-marketing program. In addition, we expect the HPV and Panther programs to consume about 40% of our direct costs. In HPV, we are on track to begin our U.S. clinical trial by the end of this quarter. Panther, we and our instrument development partner expect to focus on developing prototype systems during 2008. Moving on, we expect marketing and sales expenses to be between 9% and 10% of total revenues, consistent with 2007 levels on a percentage basis. We anticipate G&A expenses of about 11% of total revenues, which is down slightly on a percentage basis compared to 2007, reflecting tight cost controls across administrative functions. We foresee significant growth in other income in 2008, based primarily on our large and growing cash balance. That covers the major revenue and expense lines making up our initial 2008 financial guidance. But as your own analysis works towards our bottom line, I would encourage you to spend a minute on pre-tax income, since our 2007results were held by several one-time tax benefits. At the mid point, our guidance implies pre-tax income growth of roughly 30%, and this would represent our fastest on this line since 2004. With that said, we forecast that our tax rate for 2008 will increase to a more normalized rate of about 35% for the full year. I should point out however that we expect our effective rate to be a bit higher until the R&D tax credit is reinstated, then lower thereafter. All this leads to our initial 2008 earnings per share guidance of between $1.64 and $1.72 on a fully diluted GAAP basis. This guidance, which is based on weighted average of 56 million shares outstanding for the year, again represents a net profit margin in excess of 20%. We expect cash from operating activities to continue outpacing net income, with depreciation and amortization in the range of $36 million to $41 million in 2008. In addition, free cash flows should remain extremely strong. We expect capital expenditures of $50 million to $55 million in 2008, although $16 million of this is already behind us with the purchase of our blood screen manufacturing facility, which closed this month. In terms of the quarterly earnings per share splits for 2008, let me remind you that our fourth quarter results benefited from the lower effective tax rate and some non-recurring collaborative research revenue. When we normalize for these factors, incorporate a gradual sequential increase in product sales, and then add the $16 million we received from Bayer as part of the settlement of our patent infringement lawsuit, we believe our first quarter earnings per share could establish a new all-time high for the company, probably right around $0.50. So, to summarize the financial section of our conference call, our fourth quarter results capped off a very good year, in which we exceeded expectations for product sales, total revenues and earnings per share. And in 2008, we anticipate that solid top line gains can enable us to make significant investments in R&D while maintaining high levels of profitability, increasing pre-tax income at its fastest rate in four years. Now I would like to turn the call back over to Mike.
