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

On January 7, 2010, O.A.K. Financial Corporation ("OAK") entered into an Agreement and Plan of Merger (the "Merger Agreement") with Chemical Financial Corporation ("Chemical"). Pursuant to the terms of the Merger Agreement, OAK will merge with and into Chemical, and the separate corporate existence of OAK will cease (the "Merger").

OAK held a special meeting of its stockholders on April 16, 2010: (i) to approve the Merger and the Merger Agreement, and the transactions contemplated thereby (the "Merger Proposal"), and (ii) to approve an adjournment of the special meeting of stockholders, if necessary, in order to permit further solicitation and a vote of proxies in favor of the Merger Proposal (the "Adjournment Proposal").

At the special meeting, the Merger Proposal was approved by holders of OAK's common stock, with 1,842,325 shares cast "For" the Merger Proposal, 60,752 shares cast "Against," 18,157 shares "Abstaining", and zero (0) broker non-votes. The Merger Proposal received the necessary vote in favor to be adopted by shareholders at the special meeting. Because sufficient votes were received to pass the Merger Proposal, the Adjournment Proposal was not voted upon at the special meeting.

The Merger Proposal and the Adjournment Proposal are described in detail in OAK's proxy statement for the special meeting filed by OAK with the Securities and Exchange Commission (the "SEC") on March 12, 2010.

On April 16, 2010, OAK issued a press release, a copy of which is attached as Exhibit 99.1 to this report and incorporated herein by reference, in which it announced, among other things, that OAK's stockholders had approved the Merger Proposal.
