On April 26, 2016, First Clover Leaf Financial Corp. (“First Clover Leaf”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with First Mid-Illinois Bancshares, Inc., a Delaware corporation (“First Mid”), pursuant to which, among other things, First Mid agreed to acquire 100% of the issued and outstanding shares of First Clover Leaf pursuant to a business combination whereby First Clover Leaf would merge with and into First Mid, with First Mid as the surviving entity (the “Merger”).

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $0.10 per share, of First Clover Leaf issued and outstanding immediately prior to the effective time of the Merger will be converted into and become the right to receive, at the election of each stockholder, either (a) $12.87 or (b) 0.495 shares of common stock, par value $4.00 per share, of First Mid and cash in lieu of fractional shares, subject to certain adjustments, all as set forth in the Merger Agreement.

It is anticipated that First Clover Leaf Bank, National Association, First Clover Leaf’s wholly-owned bank subsidiary (“First Clover Leaf Bank”), will be merged with and into First Mid’s wholly-owned bank subsidiary, First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”), at a date following completion of the Merger. At the time of the bank merger, First Clover Leaf Bank’s banking offices will become branches of First Mid Bank. As of December 31, 2015, First Clover Leaf had total consolidated assets of $654.9 million, net loans of $420.5 million and total deposits of $533.2 million.

The Merger Agreement contains customary representations and warranties of both parties and customary conditions to the parties’ obligations to close the transaction, as well as agreements to cooperate in the process of consummating the transaction. The Merger Agreement also contains provisions limiting the activities of First Clover Leaf and First Clover Leaf Bank which are outside of the usual course of business, including restrictions on employee compensation, certain acquisitions and dispositions of assets and liabilities, and solicitations relating to alternative acquisition proposals, pending completion of the Merger.

The Merger is anticipated to be completed in the second half of 2016, and is subject to the satisfaction of customary closing conditions in the Merger Agreement and the approval of the appropriate regulatory authorities and of the stockholders of both First Mid and First Clover Leaf. Certain directors of First Clover Leaf have executed a voting agreement in which they have agreed to vote their shares of First Clover Leaf common stock in favor of approval of the Merger Agreement.

The information set forth above does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time and investors should not rely on them as statements of fact. In addition, such representations and warranties (i) will not survive the consummation of the Merger and (ii) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement and not to provide investors with any other factual information regarding First Mid or First Clover Leaf, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding, First Mid, First Clover Leaf, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into the Registration Statement on Form S-4 that will include a proxy statement of First Mid and First Clover Leaf and a prospectus of First Mid that First Mid will file with the Securities Exchange Commission (“SEC”), as well as in the Forms 10-K, Forms 10-Q and other documents that each of First Mid and First Clover Leaf file with or furnish to the SEC.

On April 26, 2016, First Clover Leaf announced that William D. Barlow, Executive Vice President and Chief Lending Officer of First Clover Leaf Bank, will be resigning from his employment effective on May 5, 2016. Effective as of May 5, 2016, the parties intend to execute a Separation and Release Agreement substantially in the form as attached hereto as Exhibit 10.1. Such agreement sets forth the terms of Mr. Barlow’s departure from First Clover Leaf Bank.

Under the Separation and Release Agreement, Mr. Barlow will receive, among other things, a lump sum payment in the amount of $525,000. Mr. Barlow will be entitled to continue receiving group health coverage under First Clover Leaf’s group health plan, to the extent required under COBRA. Mr. Barlow will continue to be eligible to receive his vested benefits under First Clover Leaf’s tax-qualified pension plans, subject to and in accordance with the terms of each such plan. Except for the foregoing, Mr. Barlow will not be entitled to other benefits under his Employment Agreement or Salary Continuation Agreement. Through May 5, 2017, Mr. Barlow will be subject to restrictive covenants with respect to his ability to compete with, or solicit employees, customers or clients of, First Clover Leaf or First Clover Leaf Bank.

In connection with the execution of the Merger Agreement discussed in Item 1.01 above, First Mid and First Clover Leaf issued a joint press release on April 26, 2016. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
