Quarterly Deposit and Funding Portfolio Trends 27 ($ in Thousands)

Second Quarter 2011 Highlights Net interest margin of 3.29%, down 3 basis points from previous quarter Impact of March 2011 debt offering (~ -8 basis points) along with the impact of lower loan yields was partially offset by a 5 bps improvement in interest-bearing deposits For the balance of the year, expect margin will be impacted by current rate environment, pace of loan growth, and net effect of funding for the expected TARP repayment Positive Results From Our Actions 28

Net Interest Income* and Net Interest Margin 29 Q2 vs. Q1 Impact on Margin During 2Q 2011, net interest income grew modestly while NIM compressed. Gross growth in interest income and lower deposit expenses, more than offset net funding expense growth, despite nearly $4 million of new CPP financing costs. Absent the CPP related interest expense, NIM would have expanded QoQ. NIM = - 3bps NII* = + $0.3 mm * NII on a Tax Equivalent Basis Earning Asset Yields = -1bps Other Liabilities= -7bps Deposit Expense = +5bps

Second Quarter 2011 Highlights Core fee-based revenue of $61M was relatively flat compared to 1Q2011 Impacted by a $6M reduction in the value of Mortgage Servicing Rights Impacted by a $4M valuation expense related to credit exposure on interest rate swap transactions Service charges on deposit accounts ($19M) were also relatively flat compared to the prior quarter Projecting NSF/OD fees of $40-45M in 2011, down ~$10 million from 2010 4Q2011 impact of Durbin will be ~$4M Annualized gross revenue impact will be $17-$19M Trust fees were $10M, up 2% from last quarter Non-interest expense of $159M was down 3% from the first quarter Positive Results From Our Actions 30

Second Quarter 2011 Highlights Credit quality continued to improve Nonaccrual loans of $468M, the lowest level in six quarters Potential problem loans down $213M (23%) from $912M for 1Q11 Provision for loan losses of $16M, down from $31M for the first quarter; expect provision will continue to decline for the balance of the year Net charge-offs of $45M, down 17% from $53M for the prior quarter; expect charge-offs will remain at about 1Q/2Q levels for the balance of 2011 Positive Results From Our Actions 31
