 2015 Actual vs. Management Original Outlook  Category  Outlook  Lending  Modest growthGoal of mid single digit % overall loan growth, primarily supported by mid single digit % growth in commercial loans and consumer loans with modest increases in mortgage loans and payment plan receivables. Expect much of this growth to occur in the last three quarters of 2015. This growth forecast also assumes a stable to somewhat improving Michigan economy. 3Q’15 Update: YTD net loan growth of $58.0 million, or 5.5% annualized. Growth concentrated in commercial and consumer installment loans.   Net interest income  Modestly higherGoal of low single digit % increase in net interest income over 2014. Pressure on the net interest margin is expected to abate by mid-2015. Growth in net interest income over 4Q’14 level expected by 2Q’15 with continued acceleration in last half of 2015 due primarily to growth in loans as described above. Forecast assumes short-term interest rates remain at current levels until 4Q’15 (modest 0.25% increase in the federal funds rates expected) and mid- to long-term rates up slightly over year end 2014 levels. 3Q’15 Update: Net interest income of $18.84 million up 0.7% over 2Q’15, also NIM was 3.58% in 3Q’15 vs. 3.62% in 2Q’15.  Provision for loan losses  Steady to slightly improving asset quality metricsVery difficult area to forecast. Future provision levels will be particularly sensitive to loan net charge-offs, watch credit levels, loan default volumes, and TDR portfolio performance. The allowance as a percentage of total loans was at 1.84% at 12/31/14. Any credit provision in 2015 would largely be a function of recoveries of previously charged-off loans, pay-downs in the TDR portfolio (permitting the release of specific reserves) and low levels of new loan defaults. 3Q’15 Update: Generally improving asset quality metrics led to $0.2 million credit loan loss provision. ALLL stood at 1.68% of portfolio loans at 9/30/15.  Non-interest income  Forecasted quarterly range of $9.5 million to $10 million with total for the year similar to 2014Expect mortgage-banking revenues and mortgage lending volumes in 2015 to be similar to 2014. Expect modestly lower service charges on deposits (continued decline in NSF occurrences and related fees) and lower other non-interest income (due to decline in rental income on ORE properties). Expect higher interchange revenue (due to full year under new debit card brand agreement). 3Q’15 Update: Actual non-interest income of $10.1 million. Includes $0.9 million impairment charge on MSR’s and $1.2 million gain on branch sale.  Non-interest expense  Forecasted quarterly range of $21 to $22 million with full year low to mid-single digit % decline vs. 2014The expected decline in non-interest expenses compared to 2014 is primarily concentrated in compensation and benefits, occupancy and equipment and loan and collection costs. This reflects the branch consolidation, staffing reductions and reduced levels of non-performing assets and watch credits. The reduced expenses are expected to be concentrated in the last three quarters of 2015. 3Q’15 Update: Actual non-interest expense of $21.9 million.   Income taxes  Approximately 31% to 32% in 2015. 3Q’15 Update: Actual effective income tax rate of 31.1%.   18  (1) Outlook as of 10/28/15 

 Strategic Initiatives  Balance SheetGenerate quality loan growth with continued focus on commercial and consumer installment lending as well as salable mortgage loans.Remain asset sensitive and positioned to benefit from higher interest rates (short duration investment portfolio, large variable rate loan portfolio and strong core deposit base with a significant amount of small to medium balance transaction accounts).Prudent capital management. Target TCE ratio – 10% to 11% near-term / 9% to 10% long- term. Priorities are: (A) capital retention to support (1) organic growth and (2) acquisitions; and (B) return of capital through (1) strong and consistent dividend and (2) share repurchase.Share repurchase plan approved for up to 5% of outstanding common shares. 382K shares repurchased in 3Q’15 (277K shares repurchased in 1H’15). In total have bought back 2.9% of outstanding common shares.Quarterly cash dividend rate on common stock increased 33% to eight cents per share effective with 11/16/15 dividend. Income StatementGenerate increased net interest income through change in earning asset mix (increased loans to deposits ratio and reduced level of investment securities).Increase non-interest income with focus on transaction related revenue (treasury management and debit card) and mortgage banking revenue.Continued reductions in non-interest expenses (credit related costs, branch optimization, process re-engineering and outsourcing).Improved efficiency ratio: 75% near-term (six to12 months); 70% mid-term (18 to 24 months) and 65% longer-term (over 24 months). Achieve improvements through combination of revenue growth and expense reductions. ROA of 1% or better by end of 2016.Enterprise Risk ManagementContinued asset quality improvements.Meet increased compliance and regulatory requirements.Focus on data security and loss prevention.   19
