Q:  Will Wolverine Bank stay “local”?
A:  The offices of Wolverine Bank will continue to serve the needs of their customers and communities.  Horizon has a closely held belief to hire and retain local talent with similar community banking values which is why we are pleased that Dave Dunn, Rick Rosinski, John Schmitt, Brian Cherry and Jeremy Clark have agreed to stay with us to help lead these efforts.  Dave, Rick and John are well-known to the customers and communities in the Great Lakes Bay Region; and Dave, Brian and Jeremy are well known in the Metro Detroit area.  They will provide considerable experience and leadership as we continue to build upon the opportunities in the great state of Michigan.

Q:  Will the locations of Wolverine Bank remain open?
A:  Yes all offices will remain open.  In addition, Horizon has pledged to open a full service office in Oakland County.

Q:  Will the office / drive up hours change?
A: Prior to systems conversion, there will be no change to office hours. We will work with the Wolverine Bank leadership team to determine if the office hours need to be reconsidered to better serve the community and share the final determination with everyone.

Q:  Do you plan to convert data processing systems?
A:  Yes.  The plan is to convert Wolverine Bank’s core data processing systems onto Horizon’s platform at a date to be determined and after the merger is completed.

Q:  Will my account numbers stay the same?
A: We anticipate there may be change to some customer account numbers.  If changes are necessary, we will share this information and work to communicate directly with those impacted customers.  In addition, it will take 30 to 60 days from date of announcement to have a final determination on this matter.

QWill I have to order new checks?
A:  It is unlikely that new checks will need to be ordered, yet is too early to determine how a systems conversion may affect the need to order new checks. We will communicate any changes as soon as they are determined.

Q:  Will the benefits and fees on my accounts change?
A:  We anticipate the change will be very minimal as we plan to maintain, or grandfather, existing accounts held by Wolverine Bank customers for a period of time.  Prior to a data processing conversion, Horizon will share any changes that may occur to existing accounts as a result of the system conversion.  If any changes are necessary, Horizon will notify all customers affected at least 30 days prior to any change.

A: Interest rates on contractual agreements like loans and certificates of deposit will remain the same in accordance with the terms of the original agreements.

Q.  When will the name change to Horizon Bank?

Q:  Will contributions to the local not for profit community decrease after the merger?
A: The contributions of both financial and human assets will continue.  These will be directed by a local advisory board to be formed shortly after the merger is closed.

Employee Questions & Answers
Horizon has a long history of retaining, hiring and promoting people from within the local community.

At Horizon, we recognize that open communication is critical to improving our business, and we therefore maintain the following approach:  1) We believe in transparency. Employees should know where they stand — as individuals, departments, and as an entire company.  2) We believe that every team member contributes to our success, and that each one’s perspective is important. So we encourage each employee to offer up their own ideas, recommendations, and concerns for discussion.  3) We have a fiduciary duty to report concerns. Horizon Bank will inevitably experience challenges to our operations — including credit quality, reporting errors, and fraud attempts. As individuals, we must report potential issues to management as soon as we become aware of them.

Q:  Will some of Wolverine Bank employees be displaced?
A:   Redundant positions may be eliminated but remote or other roles will be considered.  Also Horizon’s goal is to retain, hire and promote people from the local communities. To help ease the transition for those employees whose positions may be at risk, Horizon will offer severance payments to employees who stay through the transaction closing or data processing conversion dates.

Q:  When will Wolverine Bank employees know the status of their positions?
The target date is to notify all employees within 45 days of our merger announcement.

Q:  Will the employees who stay with Horizon retain their years of service?
A:  Yes, for the purpose of determining vesting in our retirement plans, vacations and for personal time benefits, Wolverine Bank employees who continue employment with Horizon will be given credit for their years of service.

Q:  How do Horizon’s health care plans compare to Wolverine Bank plans?
A:  Information on Horizon's insurance will be provided to Wolverine Bank employees shortly after our merger announcement.  More detailed discussions will take place during employee orientation meetings that will be scheduled at a later date.

Q:  Will retained employees be eligible for Horizon’s retirement savings plans?
A:  Yes all retained employees will be eligible for enrollment into Horizon’s 401(k) Thrift Plan and the Employee Stock Ownership Plan.

Q:  Will we receive career counseling?
A:  Yes, Horizon will provide access to career counseling services for Wolverine Bank employees not retained by Horizon.

Q:  Will personal or emotional counseling be made available?
A:  Yes, through Horizon Bank’s Employee Assistance Program (EAP).  Under this program, each Wolverine Bank employee and their immediate family members may utilize the services of a professional counselor for up to six visits.  Detailed information will be supplied on how employees may utilize this service.

Q: In past mergers with Horizon, how successful have displaced employees been able to find new jobs?
A: In past mergers Horizon has achieved over 90% placement for all displaced employees who desired to pursue new career opportunities.  In addition to career counseling, reference letters will be made available to those who request the letter and are in good standing with the company.  Horizon and Wolverine will conduct outreach efforts to other local employers on behalf of displaced employees to assist in finding job openings.
