Medical Doctors Seriously Talking at Sermo; Physician Community's Rapid Growth Indicates Extreme Value

Just 10 Days After Launch, Physician Members Log On In Large Numbers to Find Out, "Who Else Knows?" - Improving Patient Care and Identifying Trends Earlier than Ever Before Possible

Cambridge, MA - Oct. 10, 2006 - Sermo, the fastest growing online community, created by physicians for physicians, has already experienced exponential growth since its launch in late September. The exclusive community for medical doctors has continued to grow as physicians not only log on, but post observations from their daily practice, ask questions of their colleagues and share insights that help them to collaborate on unique medical situations and deliver better patient outcomes.

To date, doctors from 45 states and in 31 different specialties have registered to be a part of this groundbreaking medical community - logging nearly 5,450 votes on almost 4,000 postings submitted. MDs typically logon several times per week to pose questions about preferred techniques, promising alternative uses for medications, unanticipated drug side affects, unusual patient problems and new clinical findings. Unlike any community online, Sermo provides a protected and exclusive environment for doctors to exchange with colleagues nationwide, free of charge, and free from the usual promotions. Physicians post questions or opinions and Sermo colleagues can rank the importance or relevance of each observation. Sermo tracks the most talked about topics and reports the community's corroboration or opposition in real-time.

"We are thrilled by the quality and quantity of the information," said Founder and CEO, Daniel Palestrant, MD. "We knew we'd eventually hit a "virtuous cycle" where our early users would attract new community members who would create new content, and in turn attract even more physicians. We just never would have expected it to happen this quickly. Interestingly, our users are telling us that using Sermo is very natural. Physicians have been sharing ideas and critiquing each other's views for hundreds of years. It is the essence of peer review. The difference with Sermo is that instead of taking months, the process takes minutes. To-date, we have seen amazing conversations and postings on everything from common - but unexpected - side affects of drugs, to tips on surgical procedures and even therapeutic benefits of duct tape. It's incredibly exciting to see the potential clinical impact of Sermo grow with each passing day."

Insights Continue to Help MDs Improve Patient Care
Some postings and questions on Sermo to-date have included:

• IV abuse of leading erectile dysfunction medication?
• Is there a relationship with a leading sleep medication and retrograde amnesia?
• Are we now seeing C. Diff without antibiotics?
• A rare case of esophageal Tuberculosis?
• A role of enoxaparin in acute stroke with A. Fib?
• Herpes zoster infection and hemorrhage?
• Ataxia due to interferon A?

The answers to, or corroboration of, these and many other observations by physicians can be found on Sermo today. To sign up, go to www.sermo.com - physicians can be online and part of the conversation in just seconds.

About Sermo
Launched September 2006, Sermo is already the fastest growing online community, created by physicians for physicians.

Through Sermo, physicians exchange knowledge with each other the minute it is learned, and gain insights from colleagues as they happen instead of waiting to read about them in conventional media sources. Sermo harnesses the power of collective wisdom and enables physicians to discuss new clinical findings, report unusual events, and work together to dramatically impact patient care.
