*Paul Greig – Transcript*

Thank you, Tom, and good morning, everyone.

I am pleased to report another quarter of strong financial results. Our focus on sound banking principles continues to generate strong performance despite industry challenges from a low-interest rate environment coupled with a slow economic recovery.

Before discussing our third quarter’s financial highlights, I’d like to recap the announcement earlier this quarter of FirstMerit’s acquisition of Citizens Republic Bancorp. In September we signed a definitive agreement under which FirstMerit will acquire Citizens in a stock-for-stock transaction.

This transaction creates a unique, contiguous Upper Midwest banking franchise across five states. In addition to expanding FirstMerit’s footprint into Michigan and Wisconsin, we will also be strengthening our presence in Northeast Ohio.

Pending customary regulatory and shareholder approval we will become the sixth largest banking institution headquartered in the Midwest. The transaction is expected to close early in the 2^nd quarter of 2013.

Under the leadership of Cathy Nash and her team, Citizens made great progress over the past three years addressing legacy credit issues while growing core deposits.

We believe that combining both companies’ shared culture and values with our proven business model will enhance shareholder value.

Since we announced the transaction we have filed our regulatory applications with the Fed and the OCC. Teams throughout both companies are working together on a daily basis. Due to the significance of this transaction for FirstMerit, we have engaged a number of third parties, including Ernst & Young and Deloitte Consulting to advise us through the planning and integration process to ensure a seamless transition.

I look forward to providing additional updates with you as we get closer to becoming a single dynamic company across the Upper Midwest.

In addition to our pending geographic expansion, I want to discuss our organic growth within our existing markets. Average total non-covered commercial loans increased 13% annualized over last quarter and 12% over the prior year quarter. Our reputation as an active lender throughout the economic cycle, leveraged by our teams of experienced bankers, continues to generate profitable growth.

I’d also like to touch on our efficiency initiative that we announced in October of 2011. The reduced expenses this quarter reflect our ongoing progress. While our pending transaction with Citizens has been very visible, internally our attention to controlling expenses continues unabated. We expect to bring similar discipline to the Citizens cost structure through our integration transition.

The $108.6 million in expenses we reported this quarter was a 6.4% improvement from the year-ago quarter.

During the quarter we incurred $1.1 million in costs related to the proposed Citizens transaction as well as $500,000 related to the closing of eight full-service branches. Absent those one-time items, our operating expenses for the quarter would have been $107 million, or $3 million below our 4Q12 efficiency target.

As our loan portfolio continued to grow, our credit metrics remained solid. In the third quarter of 2012, NPAs were 77bps compared with 75bps in the second quarter. Net charge-offs were at 72bps.

Our reported NPA and net charge-off numbers reflect new regulatory guidance this quarter that reclassifies certain consumer post-Chapter 7 bankruptcy accruing loans to non-performing loans. Without the impact of this guidance, NPAs would have declined to 64bps and net charge-offs would have been 59 bps.

Now let’s review some third quarter highlights.

Our performance this quarter – despite the ongoing challenges of a sluggish economy, a low-interest rate environment and the additional costs of complying with new industry legislation – reflects a strong and financially sound company, focused on cost-efficient operations, profitable growth and increasing shareholder value.

We are growing organically in our existing markets and expanding our footprint through the Citizens transaction.

We are bringing our proven commercial growth platform and disciplined credit management practices to Michigan and Wisconsin. Since entering Chicago in 2010, we have shown that our platform is scalable and our proven management team can be leveraged in new markets.

Our solid performance in Chicago continues to validate our strategy to enter that market. We generated $317 million in commercial loan production for the first three quarters of 2012, up 11.5% over the first nine months of 2011.

We are investing in our future success in Chicago — one of the country’s most dynamic markets. In 2012, building upon that strategy we have added 28 revenue producing positions across all lines of business to the Chicago marketplace.

Chicago loan originations accounted for 25% of total originations this year with the remainder coming from our legacy regions. To that point, we continue to take market share across our footprint.

We are pleased with the strong and consistent performance in Chicago and we believe the introduction of our value proposition in our new markets of Michigan and Wisconsin will generate similar success as we bring local delivery, fast response and access to local decision makers to a new customer base.

Our focus continues to be on delivering strong financial performance for our shareholders and providing best-in-class service.

With that, I’ll turn the call over to Bill Richgels to provide more details on the credit front.
