Thanks, Jonathan and good morning everyone. I’d like to start off with an update on our two oncology programs. Intravenous PEG PH20 for solid tumors and Chemophase for bladder cancer followed by brief updates on our dermatology and bisphosphonates R&D efforts. Last month we presented efficacy date at the AACR Translational Cancer Medicine meeting in Monterey. In animal tumor models with intravenous PEG PH20, alone ending combination with either docetaxel and liposomal doxorubicin. Hyaluronan or HA is a dominant component of the extracellular matrix in subsets of many solid tumors that may increase resistance to Chemotherapy. Earlier this year we demonstrated that removal of HA around the tumor with our novel PEG PH20 enzyme results in a reduction in tumor size that exceeds NCI criteria to be considered in anti-tumor agent. HA removal also leads to significant reductions in tumor interstitial fluid pressure or IFP. And tumor Diffusion-weighted MRI signals. Many experts believe that elevated tumor IFP may limit the response to cytotoxic treatment regimens in multiple solid tumors. Our most recent studies clearly demonstrate a substantial increase in anti-tumor activity for a combination of PEG PH20 with these two chemotherapy agents. For example, in the xenograph PC-3 prostate cancer model, a tumor that produces abundant pericellular HA, tumor volume growth over time was significantly reduced and survival significantly prolonged for the PEG PH20 plus docetaxel treatment group compared to the control and docetaxel alone groups. In addition significant reductions in tumor mass were observed following treatment with pegylated enzyme alone that bears further investigation of monotherapy activity in HA expressing tumors. In contrast, using a prostate tumor model that does not produce HA, the xenograph D-145 no significant changes in IFP (inaudible) intravenous PEG PH20 treatment, the results for this HA negative model also demonstrate a no meaningful difference in tumor volume growth between docetaxel alone and PEG PH20 plus docetaxel treatment groups. These results support the proposed mechanism of action that only HA over expressing tumors are most resistible to PEG PH20 therapy. Based on our animal studies, treatment with PEG PH20 alone and with chemotherapy is well tolerated without significant increases in neutropenia compared to chemotherapy alone. These studies continue to reinforce our belief that our PEG PH20 program could lead to a potentially first in class monotherapeutic and chemo adjuvant therapeutic for HA producing solid tumors. A significant proportion of advanced cancers including prostate, breast, ovarian, pancreatic, and gastric carcinomas produce HA rich coatings which can prevent tumor cells from coming in contact with another, elevating IFP and modifying some potentially important signaling events. PEG PH20 has shown it can completely eradicate these types of sugar coatings leading to a reduction in tumor volume in IFP within hours of intravenous administration. The results we have seen so far fuel our excitement for this program and our preclinical toxicology and manufacturing efforts are continuing full speed ahead. We are making preparations to initiate studies in cancer patients using PEG PH20 during the first half of 2009. Now, moving a short distance from the prostate to the bladder for discussion of our Chemophase program. At the end of June we announced updated results of our ongoing Phase I/IIa trial in superficial bladder cancer demonstrating the safety and tolerability of induction and maintenance dosing of Chemophase, a combination of PH20 enzyme with mitomycin. This study reported no dose limiting toxicities, no observed side effects attributable to the enzyme and established the dose for subsequent clinical trials. The highest dose studied in the current trail 800,000 units of PH20 enzyme plus mitomycin will be incorporated into the future pivotal trail program. Based on the success of this ongoing trail, we are planning for meetings with FDA and European regulators in order to determine the optimal pathway to drug approval. Turning to dermatology, I would like to spend a minute talking about HTI501. HTI501 lysosomal proteinase enzyme is a new chemical entity in the lead product in our dermatology program. This new recombinant human enzyme conditionally degrades collagen and other protinatious components under the skin that form fibroseptae. Fibroseptae are fiber like anchors in the skin, they contribute to the dimpled appearance of cellulite. HTI501 may be clinically useful in medical as well as aesthetic dermatology indication such as cellulite, scarring, and Dupuytren’s contracture. It is a pH dependent enzyme with activity that we believe can be tightly controlled in the extracellular space with specific formulations. This ability to control HTI501 may be an advantage relative to collagens that tend to demonstrate persistent degradation of surrounding tissue when administered. Data for HTI501 presented at two medical meetings during the second quarter demonstrated that the enzyme can degrade collagen and vitro at pH 5 to 6, but is completely inactive at physiologic pH of 7.4. In Rat and Porcine models administration of the enzyme resulted in the release of hydroxyprolene, a marker for collagen degradation. A pH 5, but not a pH 7.4. The highly controlled the way in which HTI501 appears to show activity can prove to be differentiated and desirable attribute in the patient setting. We are moving forward with additional studies in three animal species to test efficacy to optimize formulations and the amount of enzyme to administer and gather toxicology data in support of clinical trails which we are targeting to begin by the end of next year. Cell lines that express HTI501 have been transferred in to our manufacturing group for CGMP process development and scale up. Turning to osteoporosis our fifth proprietary initiative is our bisphosphonate PH20 program for osteoporosis, which targets a multi billion dollar market that includes both oral and intravenous products. IV bisphosphonates offer some advantages over the oral products which see patient discontinuation rates of 50% within 12 months of starting treatment due to GI side effects. However, IV administration represents an inconvenience to patients and to general practitioners who generally do not have the ability to administer IV medications. The subcutaneous administration of bisphosphonates alone without PH20 produce unacceptable skin irritation and the injection side reactions for the patients. For these reasons our market research has concluded that a convenient subcutaneous in-office bisphosphonate treatment would result in a strong willingness amongst physicians to treat osteoporosis to prescribe our product. In animal studies that we’ve conducted, co-administration of bisphosphonate with PH20 demonstrates comparable bioavailability for sub-Q injection relative to IV. And the ability to administer much higher doses of bisphosphonate as much as three to five folds without significant injection side reactions. Based upon the favorable pre-clinical results we’ve seen so far, we are targeting to enter the clinic with the bisphosphonate PH20 combination formulation by the end of the year. Now I’ll turn the call over to Bob Little, who’ll update you on our partnered programs.
Robert Little – Chief Commercial Officer: Thank you, Greg and good morning. We currently have three partnerships in place with two companies Roche and Baxter BioScience for Enhanze Technology and a partnership with Baxter Medication Delivery for HYLENEX, our FDA approved drug. Let’s start by discussing Halozyme’s partnership with Roche. Overall our Roche line is moving forward exactly as planned. For example we are continuing to successfully implement the scale-up of a higher yielding PH20 enzyme manufacturing process that will support Roche’s needs as well as Halozyme’s internal programs. The recent bid by Roche to acquire the portion of genetic, it does not already owned may have made some of you wonder what it means to the future of the Halozyme partnership. Our deal already grounds Roche and all of its affiliate’s worldwide rights to apply in our Enhanze Technology to 13 biologic targets and specifies three of the targets on an exclusive basis. Therefore we see no material impact on our relationship if and when the genetic acquisition offer closes. We have to provide more details regarding the status of the Roche programs by the end of this year. Our second Enhanze Technology partnership is with Baxter Bioscience. And in March, Baxter presented positive results from their GAMMAGARD Enhanze Technology Phase I/II clinical trial at the American Academy of Asthma, Allergy, Immunology Conference known as the AAAAI. Currently Baxter is preparing to begin its Phase III clinical trial for the GAMMAGARD Enhanze combination in early 2009. Also in late July positive nine month interim data from a Phase II trial testing GAMMAGARD and Alzheimer’s Disease was presented Alzheimer’s Association meeting. Baxter has committed its plans to conduct further studies in this patient population and additional favorable results could expand the use of GAMMAGARD. Investment analysts peg the growing world about GAMMAGARD franchise of roughly $1 billion of annual sales. Administration of this lifelong therapy for primary immunodeficiency and other potential uses in the future in the home setting by a subcutaneous administration could provide greater patient convenience as well pharmacoeconomic benefits. Moving on to Baxter Medication Delivery regarding the Baxter, HYLENEX relationship. Our belief remains strong of this partnership and the HYLENEX product have significant patient benefit as well as sales potential. The segment that Baxter is currently targeting is the ophthalmic or ambulatory surgical centers, pediatric hydration and the long-term care on nursing home market. Baxter has stated in the past that believes the product represents $500 million annual sales opportunity. Introduction into the ophthalmic surgery market a niche opportunity just started during the second quarter for the most significant launches in pediatric and long-term care market should be rolling out during next year. Enrollment in the Multi-center infused pediatric re-hydration study that involves leading pediatric hospitals is now complete. Results of this study should be available in October and it will prove highly useful as Baxter launches HYLENEX into the pediatric market during 2009. With regards to the long-term care market, we believe that HALO is going to offer nursing home inclinations are cost affective and patient friendly alternative to hospitalization by allowing subcutaneous hydration in the nursing home setting. Baxter is currently gathering health economic data for least facilities in owe to better understand the cost benefit implications of subcutaneous administration. We at Halozyme remain very encouraged by the strong commitments as Baxter’s top management has expressed to invest in the commercial and clinical support for HYLENEX and its push for opportunities in new markets. Finally, taking now about other enhanced technology partnership opportunities, I have to say our discussion activity with multiple potential partners is more active now than it ever has been. And they are exploring kind of the use of our enzyme with their proprietary drug and biologic compounds. Additional development partnership structures with the right terms and with the right partner remain an important objective for Halozyme. I’ll turn the call now over to David. Thank you.
David Ramsay – Chief Financial Officer: Thank you, Bob and good morning everyone. The net loss for the second quarter 2008 was $11 million or $0.14 per share compared with the net loss for the second quarter of 2007 of $4.8 million or $0.07 per share. For the six months our net loss totaled $21 million or $0.27 per share compared to $8.2 million or $0.11 per share during the first half of 2007. Revenues for the second quarter of 2008 were $1.4 million compared to $709,000 for the second quarter of 2007. Revenues under collaborative agreements for the second quarter 2008. Were also $1.4 million compared with $539,000 for the second quarter of 2007. Revenues under collaborative agreements in 2008 primarily consisted of the amortization of upfront fees received from Baxter and Roche, totaling $588,000 and then also research and development reimbursements from Baxter totaling $554,000 and Roche of $210,000 during the period. R&D expenses for the second quarter of 2008 were $8.9 million compared with $4.1 million for the second quarter of 2007, reflecting increased compensation expense largely due to the increase in our research and development personnel as well increased R&D spending on our insulin, bisphosphonates and PEG PH20 clinical and preclinical program, as well as the increase production cost associated with the manufacturing scale-up of our PH20 enzyme. SG&A expenses for the second quarter of 2008 were $3.8 million compared with $2.4 million for the comparable period in 2007, reflecting increased compensation expenses as well as higher legal and facilities expenses as compared with prior year quarter. We remain in a very strong financial position with cash and cash equivalents of $82.4 million as of June 30, 2008, compared with $97.7 million as of December 31, 2007. That concludes my prepared remarks and now, I’ll turn the call back over to Jonathan.
