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

Key 3Q09 Credit Trends

Non-performing loans were flat from 2Q09 and are expected to plateau — through the end of 2010 then decline

Inflows to non-performing assets decreased for the second quarter in a row

Delinquency trends for the past 2 quarters show great progress and are down from peak levels a year ago by $105 million Continued to build reserve with provision for loan losses exceeding net charge-offs by $6 million; trending toward matching NCOs

— our Allowance peers (peer for loan average losses 1 to.95%) total loans increased to 4.13%, higher than all of

Consumer portfolio continues to perform well (minimal 2006 — 2007 vintage) Solid commercial (non-CRE) loan performance

— De-risked in 2002 — 2004 — Past due loans down to 0.96% from 2.17% in 4Q08

Majority of historical stress was from the smallest portfolio (Land Hold, Land Development & Construction) Proven success in loan work out In past credit cycles, when nearing the end, frequency decreases and severity increases. Based on historical cycles:

— provision We expect expense 2010 net trending charge towards -offs to be matching equal to NCOs or higher than 2009 with — We expect 2011 to show a dramatic drop in net charge-offs

Loss Mitigation & Workout Strategy

Commercial loan workout teams (>50 FTE) focused on loss mitigation by specific asset classes, with account assignment based on asset liquidation expertise of personnel Enhanced collections efforts and administrative discipline led to improved delinquency and loss mitigation results Quarterly internal analysis of industry-related exposures updated based on segments and asset classes facing the greatest potential recessionary impact

(i.e. auto-related, income producing real estate) Continuously evaluate consumer payment histories and proactively seek to modify loan structures to mitigate potential loss given default 30

Proven Success in Loan Work Out

Transferred riskiest assets to LHFS classification which are written to liquidation values

— 1Q07 transferred $103.7 million in conjunction with Republic integration, recognized $35.1million write-down with transfer — 2Q08 transferred $127.9 million, recognized $35.1 million write-down with the transfer, accelerating loss recognition Loans held for sale balances are decreasing Continue to work with existing borrowers when appropriate in order to optimize long-term remaining value of collateral

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

Remain Client Focused

We are still lending despite the decline in credit demand during 2009

— Extended, renewed and approved $2.4 billion of loans year to date Citizens is the #1 SBA lender in Michigan for the 2nd year in a row Continue to lend responsibly based on creditworthiness of the borrower and collateral strength Aligned infrastructure to be more focused on consumer, small-business, and lower middle market relationships Continued cost management 33

Protect and Manage Liquidity

Deposit pricing — aggressive, but not top of the market

— Grow deposits from our footprint, our clients Pick our spots — Focus on where we can grow with less margin impact and a better return on advertising spend — Understand impact of our strategy — might move some core into time Balance liquidity strategy within overall strategy — Despite liquidity cost overhang, net interest margin spreads are strengthening 34
