Strong Balance Sheet Immediate Credit-Related Priorities Simple, Focused Approach

Focus #1: Stay Client FocusedDespite the decline in credit demand during the 4th quarter, we – Extended $135 million of new commercial loans – Renewed over $300 million of commercial loans – Approved $170 million of consumer loansExpanded SBA lending initiatives – Citizens is the #1 SBA lender in MichiganContinue to lend responsibly based on creditworthiness of the borrower – while not lowering our lending standards and in fact tightening them in some casesContinue investment in our communities

25

Focus #2: Strategic PlanningKnow who we are – Primarily a retail and small business bank – High client retention – Strong branch modelUnderstand our portfolio – Where are our risks? – How do we manage for them appropriately?What do we want the bank to look like? – Build support, tracking, measurements, incentives around that – How do we get there? 26

Focus #3: Protect and Manage LiquidityBe aggressive, but not top of the market – We’d rather grow deposits from our footprint, our clientsPick our spots – Where we can grow with less margin impact and a better return on advertising spend, we will focus there – Understand impact of our strategy – might move some core into timeUnderstand liquidity strategy within overall strategy 27 27

Focus #4: Manage ExpensesExpenses are rising – FDIC Insurance Costs – Benefits – Non Accrual LoansBe wary of expense diets – Short term fixes often unsustainableBuild new ways of delivering to client into strategic planning such as – In branch image capture – Mortgage outsourcing 28 28
