[CITIZENS LOGO] Exhibit 99.5 CITIZENS BANKING CORPORATION CUSTOMER QUESTION AND ANSWER GUIDE We are pleased to announce that Citizens Banking Corporation and Republic Bancorp have signed an agreement under which Republic will merge into Citizens. Pending necessary approvals, the merger is expected to close late in the 4th quarter of 2006. Q: WILL THE BANK NAME CHANGE? A: As the merger is approved and we integrate both banks, we will change the name of branch locations to Citizens Republic Bancorp. This will allow you to bank at branch locations in four Midwest states including Michigan, Wisconsin, Ohio and Iowa. Q. WHAT ARE THE BENEFITS OF THE MERGER FOR BOTH ORGANIZATIONS? A. Citizens Republic Bancorp will represent a strong regional brand better positioned to compete with super-regional as well as community banks. The existing corporate cultures and strategies for both companies are very compatible. Both teams are committed to a strong sales and service philosophy which will lead to future growth and enhanced shareholder value. Citizens Republic Bancorp will provide a full complement of commercial, wealth management, and specialty lending products to Republic customers, as well as enhance SBA, commercial real estate and mortgage banking services for Citizens customers through 275 branch and loan production offices. This partnership will increase our Southeast Michigan presence to 39 locations. Citizens Republic Bancorp will have almost 5% of the total deposits in Michigan, with over 35% of its deposits in high growth markets. Q. AS A CUSTOMER, HOW WILL I BE AFFECTED BY THIS CHANGE? A. The merger will offer customers enhanced convenience through a greatly expanded branch network. We are committed to a relentless focus on our customers and will work closely together as partners to assure there is minimal disruption. For now, nothing will change for the customers of either organization. Citizens Bank and Republic Bank customers will not be able to make transactions at the partner locations until after our systems are integrated which is expected to occur in the first quarter of 2007. Q: WILL MY ACCOUNT CHANGE? A: At this time, your account(s) will remain the same. As we work to bring both banks together, we will offer expanded services and products for consumers and businesses. More information will be provided in coming months. As always, we will continue to work with you to find the right accounts to fit your banking needs. Q: CAN I USE MY SAME CHECKS? A: Yes, you should continue to use your same checks. In addition, customers should also continue to use the same ATM, Debit/Check Cards, and Credit Cards. Q. WILL YOU SELL OR CLOSE BRANCH OFFICES? A: We will evaluate all of our markets to ensure that we have proper branch coverage to service our customers. Branch divestitures in some of our markets may be required by the regulators. All of this will likely result in some consolidation and closures of branches but it is too early for us to speculate on specific details. 1 Q. WILL YOU CONTINUE TO SUPPORT OUR LOCAL COMMUNITIES? A. Both organizations are dedicated to improving the quality of life in the communities we serve. We will continue our support of the communities in which our customers and associates work and live. Q.
