Frequently Asked Questions

August 6, 2014

EMPLOYMENT QUESTIONS

Do I continue performing my current duties, projects, and reports?

Yes, until the partnership closes, Lafayette Savings Bank employees should each continue to perform their current duties. Projects scheduled in the future will be evaluated on a case-by-case basis with your senior manager to determine its priority.

Will Lafayette Savings Bank officer titles be retained by Old National?

Yes, your officer title (i.e. AVP, VP, etc.) will transfer to Old National.

If an associate is retained by Old National and is offered a position paying less, is severance pay still available to that person if they decline the offer?

Associates are eligible for severance benefits when offered a position that is considered “not comparable”. A comparable position is one in which the pay is not less than 90% of the employee’s current compensation.

What happens if I have a job offer elsewhere before I’ve been informed of my future with Old National?

If you receive a job offer, you should consult with your manager so that we can work together to give you as much information as we can to help support your decision-making process. We previously communicated that all revenue producing positions will continue after the closing (e.g., Mortgage Originators, Commercial Lenders, etc.), including all retail positions in the branches.

If my job is eliminated, is severance only available if I work through the last day my job exists? Will this occur at closing or conversion?

To qualify for severance from Old National, an employee experiencing job loss must work through his/her release date. The release date will occur after the conversion. And for most, it will be two to three weeks following conversion. Once we have made decisions about positions, we will communicate a specific timeframe for the job eliminations to occur.

Is severance affected by a person’s retirement?

No, whether or not an employee (whose job will be lost) chooses to retire has no bearing on his/her eligibility for severance benefits provided he/she meets the severance plan eligibility requirements.

Is severance affected if Old National offers another position for someone and they turn it down?

If the employee declines a comparable position, he/she would not be eligible for severance. Comparability is determined by management based on commuting distance, compensation (discussed above) and the job responsibilities.


TIME OFF QUESTIONS

What will happen to my current and carry over PTO balances?

As part of the gap analysis process, we are actively reviewing the PTO program to determine how best to transition to Old National’s time off programs. We realize employees are eager to learn the outcome of this analysis and commit to completing this process in as timely of a manner as possible.

Will there be a requirement to fulfill the 5 consecutive day PTO requirement in 2014?

Yes. As a good risk management practice, both Lafayette Savings Bank and Old National Bank have a requirement for associates to be out 5 consecutive days in year.

401(k) QUESTIONS

What will happen to my 401(k) match for 2014?

Lafayette Savings Bank will make any required matching contributions into the plan until the plan is terminated.

How is my current vesting impacted, if any?

Balances in the Lafayette Savings Bank plan become vested when the plan is terminated. Participant deferrals and matching contributions become immediately vested under Old National’s plan.

BENEFITS

Is it possible to provide a comparison of Lafayette Savings Bank insurance benefits and rates with those of Old National?

A benefit comparison and premium information will be provided in a separate communication.

How will COBRA work for people who leave and under whose plan will it be available?

An employee’s eligibility for COBRA is not affected by the partnership. More information on COBRA options will be provided once we determine the timing for associates to enroll and transition to Old National’s benefit plans.
