Lloyd’s Syndicate 1729 Update 25 First policies underwritten January 1, 2014 $46.9 million in gross premiums written (to ProAssurance) for the nine months reported 9/30/15 Current capacity for 2015 is approximately $113.5 million ProAssurance is providing 58% of underwriting capital $65 million in underwriting capital for 2015 Six - Year commitment of up to $200 million Remaining capital from other corporates and private names Benefits to ProAssurance Diversification Opportunities to participate in international healthcare liability Meet needs of U.S. insureds with international business

Healthcare Realities American healthcare is wrestling with the question of cost vs. care — we 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 27 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

Healthcare Realities The Affordable Care Act (ACA) is creating additional layers of complexity Healthcare delivery will be in continuous flux for years to come Will additional coverage under the ACA help or hurt Worker’s Compensation writers? Will the healthcare burden shift Potential liability effects of the ACA High deductible health plans – higher patient expectations, delayed care, collection disputes Provider consolidation – impersonal care More patients – longer waits, increased frustration New providers – lack of continuity of care 28

Insurance Marketplace Realities 29 Insurance companies are awash in capital Pressure is mounting to “do something” with it M&A — the hunter vs. the hunted Chase market share with low prices but disastrous long - term consequences Appease investors or policyholders with unwise capital - return strategies For many traditional MPL companies, it is “the fork in the road”
