Item 5.07. Submission of Matters to a Vote of Security Holders

On April 26, 2013, the Corporation held the Annual Meeting of Shareholders pursuant to due notice. Three directors were elected to the following terms, by the following votes. Holders of a total of 2,047,699 shares were present in person or by proxy at the meeting.

The proposition described below, having received a vote, in person or by proxy, of more favorable votes than votes cast against the proposition, was declared to be duly adopted by the shareholders of the Corporation.

The proposition described below, having received an advisory vote, in person or by proxy, of more favorable votes than votes cast against the proposition, was declared to have been adopted:

The Corporation’s shareholders voted, on an advisory basis, on the frequency of future “say-on-pay” votes as follows:

At the Annual Meeting, shareholders cast over 91% of votes in favor of holding future say-on-pay votes on an annual basis. The Corporation’s Board of Directors had recommended a vote for annual frequency of say-on-pay votes. In light of this result and other factors it considered, the Board has determined that the Corporation will hold future say-on-pay votes on an annual basis until the next advisory vote on the frequency of say-on-pay votes occurs. The next advisory vote regarding the frequency of say-on-pay votes is required to occur no later than the Corporation’s 2019 Annual Meeting of Shareholders.
