Strategic Review

Key High - Level Strategies We have built a platform to address the challenges of the evolution of healthcare The creation of new delivery systems and entities is changing the competitive landscape in healthcare professional liability Financial strength and broad geographic reach are now simply “table stakes” Coverage flexibility and alternative risk solutions are the differentiators We will remain healthcare - centric as we address a broad array of liability risks for our insureds We will continue to enhance shareholder value thought effect capital management 8

The Reality of Healthcare Healthcare cost is the main event. The Affordable Care Act is a side show America can deliver more care than we can afford Restructuring is producing profound changes in healthcare Healthcare delivery is being pushed down to lower cost providers The U.S. spends a greater proportion of GDP on healthcare and the percentage is increasing but results don’t measure up 9 6.0% 8.0% 10.0% 12.0% 14.0% 16.0% 18.0% 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Healthcare Spending as a Percentage of GDP (1995 - 2013) US France Germany OECD Global Japan UK

The Reality of Insurance 10 Insurance companies are awash in capital Pressure is mounting to “do something” with it Chase market share with low prices but disastrous long - term consequences Appease investors or policyholders with unwise capital - return strategies M&A will emerge, but may be more critical for smaller competitors seeking the size and scope to address the market For many traditional MPL companies, it is “the fork in the road,”

Establishing our Platform 11 Early M&A built out our medical professional liability business by building scope and size We added capabilities through subsequent M&A PICA: podiatric and related specialties Medmarc: life sciences and medical technology ProAssurance Mid - Continent Underwriters: ancillary healthcare New product development to support emerging risks for our healthcare insureds The acquisition of Eastern Insurance Alliance allows us to provide workers’ compensations solutions and provides proven alternative market solutions through segregated cell capabilities The other pillar of liability for healthcare organizations
