PRELIMINARY – SUBJECT TO COMPLETION – DATED SEPTEMBER 30, 2016

MERGER PROPOSED – YOUR VOTE IS VERY IMPORTANT

Proxy Statement and Prospectus of Middlefield Banc Corp. |  | Proxy Statement of Liberty Bank, N.A.

MERGER PROPOSAL – YOUR VOTE IS VERY IMPORTANT

Middlefield Banc Corp. (“Middlefield”) and Liberty Bank, N.A. (“Liberty”) entered into an Agreement and Plan of Reorganization on July 28, 2016. We refer to the agreement as the Reorganization Agreement. A copy is attached to this joint proxy statement/prospectus as Annex A. The Reorganization Agreement provides that Liberty will merge into The Middlefield Banking Company, which is Middlefield’s bank subsidiary. The merger is subject to a number of conditions, including but not limited to obtaining approval of Middlefield stockholders, approval of Liberty stockholders, and approval of state and federal bank regulatory agencies.

Approximately 45% of the Liberty shares of common stock exchanged in the merger will be exchanged for Middlefield common stock, and the remaining Liberty shares of common stock exchanged in the merger (approximately 55%) will be exchanged for cash. Each share of Liberty common stock not owned by Middlefield will be converted at the effective time of the merger into the right to receive either: (x) $37.96 in cash or (y) 1.1934 shares of Middlefield common stock, subject to allocation procedures to ensure that approximately 45% of the outstanding shares of Liberty common stock are converted into Middlefield common stock and the remaining Liberty common stock is converted into cash. Excluding the 23,218 Liberty shares owned by Middlefield, which will be cancelled in the merger without consideration, the aggregate consideration payable to Liberty stockholders is approximately $19.1 million in cash and approximately 515,164 shares of Middlefield common stock. On July 27, 2016, the day before execution of the Reorganization Agreement, the per share closing price of Middlefield common stock on the Nasdaq Capital Market was $33.74. At that price the stock portion of the merger consideration would have a value of approximately $17.4 million, and combined with the approximately $19.1 million cash payable for 55% of Liberty common stock, the total merger consideration would be $36.5 million, before the special dividend discussed below. Because the 1.1934 exchange ratio is fixed, the value of the 45% stock portion of the total merger consideration will fluctuate with changes in the price of Middlefield stock. Holders of Liberty stock options and phantom shares also will receive $1,147,516 in cash for cancellation of those interests. Finally, in addition to the cash and stock merger consideration, Liberty stockholders will receive a special dividend of approximately $3.0 million in the aggregate, or $3.13 per share, before merger closing. Middlefield will receive no merger consideration for its 23,218 Liberty shares but it will be entitled to a proportionate share of the special dividend payment. See “SUMMARY – What Liberty stockholders will receive in the Merger.”

Middlefield will not issue fractional shares. A holder of Liberty common stock who would otherwise be entitled to a fractional share will instead receive cash, without interest, equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

Middlefield and Liberty will each hold a meeting of stockholders to vote on adoption and approval of the Reorganization Agreement. The meeting of Middlefield’s stockholders will be held at: 10:00 a.m. local time on , 2016 at , Ohio. The meeting of Liberty’s stockholders will be held at: 10:00 a.m. local time on , 2016 at , Ohio. At these meetings stockholders will be asked to approve and adopt the Reorganization Agreement and the merger transaction. Stockholders will also be asked to approve adjournment of the meeting, if adjournment is necessary to allow Middlefield and Liberty time to solicit additional proxies in favor of the Reorganization Agreement and the merger transaction. Liberty’s stockholder meeting is an annual meeting, so Liberty stockholders will also be asked to act upon routine annual meeting proposals, including election of directors and ratification of the appointment of independent auditors.

This document is a proxy statement of both Middlefield and Liberty. It is also a prospectus for Middlefield’s issuance of common stock in the merger. This joint proxy statement/prospectus describes Middlefield’s special meeting, Liberty’s annual meeting, and the merger proposal.

The board of directors of Middlefield and the board of directors of Liberty approved the Reorganization Agreement and the merger transaction. They recommend that their stockholders vote “FOR” adoption and approval of the Reorganization Agreement and “FOR” adjournment of the meeting if adjournment is necessary.

Middlefield’s common stock trades on the Nasdaq Capital Market under the symbol “MBCN.” On July 27, 2016, the day before execution of the Reorganization Agreement, the closing price of Middlefield common stock was $33.74 per share. On , 2016 the closing price of Middlefield common stock was $ per share. Liberty common stock is privately held, not listed on a stock exchange, and not traded in the over-the-counter market.

You are encouraged to read this document carefully, including the materials incorporated by reference into this document. In particular, you should read the “Risk Factors” section beginning on page 28 for a discussion of the risks related to the merger and the risks of owning Middlefield common stock.

Regardless of whether you plan to attend your company’s stockholder meeting, you are urged to vote by completing, signing, and returning the enclosed proxy card in the enclosed postage-paid envelope.

If you are a Liberty stockholder as of the , 2016 record date but your shares are not voted in favor of adoption and approval of the Reorganization Agreement, you have the right to demand the fair cash value for your Liberty common stock but to do so you must adhere to the specific requirements of the National Bank Act, 12 U.S.C. §215, paragraphs (b), (c), and (d). See “DISSENTERS’ RIGHTS” on page of this joint proxy statement/prospectus and the complete text of the National Bank Act dissenters’ rights provision attached to this joint proxy statement/prospectus as Annex B. Holders of Middlefield common stock do not have dissenters’ rights.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE STOCKHOLDER MEETINGS

The following questions and answers cover some of the questions most likely to arise about the stockholder meetings. We urge you to read carefully the remainder of this joint proxy statement/prospectus because this section does not necessarily contain all information that is important to you. Additional important information is also contained in the appendices to and in the documents incorporated by reference in this document.

Q: | Why am I receiving this joint proxy statement/prospectus?

A: | You are receiving this joint proxy statement/prospectus because Liberty Bank, N.A. (“Liberty”) agreed to merge into The Middlefield Banking Company by the terms of a July 28, 2016 Agreement and Plan of Reorganization (the “Reorganization Agreement”) entered into by Liberty, Middlefield Banc Corp. (“Middlefield”), and The Middlefield Banking Company, and to be executed by MBC Interim Bank, an interim state-chartered commercial bank to be incorporated under the laws of the state of Ohio (“MBC Interim Bank”). The Middlefield Banking Company is and will remain a wholly owned subsidiary of Middlefield. Pursuant to the Reorganization Agreement, Liberty and MBC Interim Bank will merge with and into Liberty with Liberty surviving that merger (the “Interim Merger”), and immediately thereafter Liberty will merge with and into The Middlefield Banking Company with The Middlefield Banking Company surviving that merger (the “Bank Merger,” and considered together with the Interim Merger, the “Merger”). The Reorganization Agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated herein by reference. The Merger cannot be completed unless Liberty stockholders and Middlefield Banc Corp. stockholders vote to approve and adopt the Reorganization Agreement and the transactions contemplated by the Reorganization Agreement.

This joint proxy statement/prospectus contains important information about the Merger and the stockholder meetings of Middlefield and Liberty. You should read the joint proxy statement/prospectus carefully. The enclosed proxy voting materials allow you to vote your company’s common stock without attending the meeting.

Q: | What will Liberty stockholders receive in the Merger?

A: | Liberty stockholders will receive a combination of cash and Middlefield common stock, in addition to a special dividend of approximately $3.13 per share in cash immediately prior to the completion of the Merger. Subject to Reorganization Agreement allocation procedures ensuring that approximately 45% of the outstanding Liberty common stock is converted into the right to receive Middlefield common stock and the remaining outstanding Liberty common stock is converted into the right to receive cash, at the effective time of the Merger Liberty common stock not owned by Middlefield will be converted into the right to receive either:

| • |  | $37.96 in cash, or

| • |  | 1.1934 shares of Middlefield common stock

On July 27, 2016, which was the day before public announcement of the proposed Merger, the closing price of Middlefield common stock on the Nasdaq Capital Market was $33.74. Based on that price for the stock portion of the Merger consideration and $37.96 per share for the cash portion, a Liberty stockholder who receives stock for 45% of his or her common stock at the 1.1934 fixed exchange ratio and cash for 55% would receive total Merger consideration with an implied value of approximately $39.00 per share, in addition to a special dividend of approximately $3.13 per share in cash. As of the more recent , 2016 date, the closing price for Middlefield common stock was $ . At that price and giving effect to the 1.1934 fixed exchange ratio, the implied value of a share of Liberty common stock exchanged for Middlefield common stock is $ . At this more recent price for Middlefield common stock, a Liberty stockholder who receives stock for 45% of his or her shares and cash for 55% would receive total Merger consideration with an implied value of approximately $ per share.

##### Table of Contents

Middlefield will not issue fractional shares. Instead, a holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all shares of Liberty common stock owned by the holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

It is not part of the Merger consideration, but the Reorganization Agreement also provides that Liberty will declare a special dividend to stockholders before the Merger closes (or becomes effective). The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will receive no Merger consideration for its 23,218 Liberty shares but will be entitled to a proportionate share of the special dividend payment.

Q: | Will Liberty stockholders be able to make an election for the form of merger consideration they desire to receive?

A: | Yes. If you are a Liberty stockholder you will have the opportunity to elect the form of consideration to be received for your shares, but your election will be subject to adjustment and allocation procedures set forth in the Reorganization Agreement ensuring that approximately 45% of the outstanding Liberty common stock is converted into the right to receive Middlefield common stock and the remaining outstanding Liberty shares are converted into the right to receive cash. Therefore, your ability to receive the cash or stock elections of your choice depends on the elections made by other Liberty stockholders. The allocation of the mix of consideration payable to Liberty stockholders in the Merger will not be known until Middlefield tallies the results of the cash and stock elections made by all Liberty stockholders, which will likely not occur until shortly after Merger closing.

It is unlikely that Liberty stockholders as a group will elect to receive precisely 55% of the Merger consideration in cash and the remainder in Middlefield common stock. For that reason the Reorganization Agreement contains procedures to be followed if Liberty stockholders in the aggregate elect to receive more or less of the Middlefield common stock than Middlefield has agreed to issue –

| • |  | If Stock Is Oversubscribed: If Liberty stockholders elect to receive more shares of Middlefield common stock than Middlefield is issuing, all Liberty stockholders who elect to receive cash or who make no election will receive cash for their Liberty shares; stockholders who elect to receive Middlefield common stock will receive a pro rata portion of the available Middlefield shares, receiving cash for shares not converted into Middlefield common stock.

| • |  | If Stock Is Undersubscribed: If Liberty stockholders elect to receive fewer shares of Middlefield common stock than Middlefield is issuing, all Liberty stockholders who elect to receive Middlefield common stock will receive Middlefield common stock; stockholders who elect to receive cash or who make no election will be treated in the following manner:

| • |  | if the number of shares held by Liberty stockholders who make no election is sufficient to make up the shortfall in the number of shares of Middlefield common stock that Middlefield is issuing, Liberty stockholders who elect cash will receive cash; stockholders who make no election will receive Middlefield common stock in such proportion as is necessary to make up the shortfall, receiving cash for the remainder, and

| • |  | if the number of shares held by Liberty stockholders who make no election is not sufficient to make up the shortfall, Liberty stockholders who make no election will receive Middlefield common stock; Liberty stockholders who elect to receive cash will receive Middlefield common stock in such proportion as is necessary to make up the shortfall, receiving cash for the remainder.

You might not receive the amount of cash or stock you elect. As a result of the allocation procedures and other limitations outlined in this document and in the Reorganization Agreement, you may receive Middlefield common stock or cash in amounts that vary from the amounts you elect to receive.

Q: | How do Liberty stockholders make their election to receive cash, Middlefield common stock, or a combination of both?

A: | Each Liberty stockholder of record will receive an election form to be completed and returned. The election deadline will be 5:00 p.m., Eastern Time, on [30 days after the date of this joint proxy statement/prospectus] , 2016, which we refer to as the “election deadline.” A copy of the election form is being mailed separately to Liberty stockholders on or about the date of this joint proxy statement/prospectus.

If you own Liberty shares in “street name” through a bank, broker, or other nominee and you wish to make an election, you should seek instructions from the bank, broker, or other nominee holding your shares concerning how to make an election. If you do not send in the election form with your stock certificate(s) by the election deadline, you will be treated as though you made no election.

Q: | Will I be allowed to change my election?

A: | Yes. Until the election deadline you may change your election by submitting to American Stock Transfer & Trust Company, LLC written notice accompanied by a properly completed and signed, revised election form. After the election deadline you will not be allowed to change or revoke your election. If you instructed a bank, broker, or other financial institution to submit an election for your shares, you must follow their directions for changing those instructions.

Q: | What happens if I do not make a valid election to receive cash or Middlefield common stock?

A: | If you do not return a properly completed election form by the election deadline specified in the election form, your Liberty common stock will be considered “non-election shares” and will be converted into the right to receive the stock consideration or the cash consideration according to the allocation procedures specified in the Reorganization Agreement. Generally, if one form of consideration (cash or Middlefield common stock) is undersubscribed, Liberty common stock for which no election is validly made will be allocated to the undersubscribed form before shares electing the oversubscribed form are allocated to the undersubscribed form. If proration becomes necessary, shares for which a valid election is made will have priority over non-electing shares, although electing a particular form of consideration does not guarantee that your election will be honored in full.

Q: | What are the material U.S. federal income tax consequences of the Merger to Liberty stockholders?

A: | Tucker Ellis LLP has delivered its legal opinion, dated September 26, 2016, to the effect that the Merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (which we refer to as the “Internal Revenue Code”). In addition, the completion of the Merger is conditioned on receipt of a tax opinion from Tucker Ellis LLP, dated as of the closing date, to the same effect. However, neither Liberty nor Middlefield has requested or received a ruling from the Internal Revenue Service that the Merger will qualify as a reorganization or as to any other aspect of the Reorganization Agreement or the transactions contemplated by it. The U.S. federal income tax consequences of the Merger to a Liberty stockholder will depend on the relative mix of cash and Middlefield common stock received by that Liberty stockholder. Liberty stockholders should not recognize any gain or loss for U.S. federal income tax purposes if they exchange their Liberty shares solely for shares of Middlefield common stock in the Merger, except with respect to cash received in lieu of fractional shares of Middlefield common stock. Liberty stockholders will recognize gain or loss if they exchange their Liberty shares solely for cash in the Merger. Liberty stockholders will recognize gain, but not loss, if they exchange their Liberty shares for a combination of Middlefield common stock and cash, but their taxable gain in that case will not exceed the cash they receive in the Merger. The special dividend is not part of the Merger consideration. It will be taxable to Liberty stockholders as ordinary income, taxable at preferential rates applicable to “qualified dividends.” Any gain recognized on the Merger consideration and any ordinary income from the special dividend could be subject to an additional tax on “net investment income,” depending on the individual’s adjusted gross income, as described below under “– Medicare Tax on Net

| Investment Income.” You should consult with your tax advisor for the specific tax consequences of the Merger and the special dividend to you. See “Material U.S. Federal Income Tax Consequences” on page .

The consequences of the Merger to each Liberty stockholder depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine the tax consequences of the Merger to you.

Q: | Is Liberty allowed to pay dividends before the effective date of the Merger?

A: | Yes. Under the terms of the Reorganization Agreement, Liberty is permitted to pay usual and customary cash dividends. The Reorganization Agreement also requires Liberty to declare a special dividend before closing. The amount of the special dividend may change, but it currently is estimated at approximately $3.0 million in the aggregate, or $3.13 per share.

Q: | When and where will the Middlefield and Liberty stockholder meetings be?

A: | Middlefield’s special meeting of stockholders will be held at a.m., local time, on , 2016 at , Ohio . The annual meeting of Liberty stockholders will be held at a.m., local time, on , 2016 at , Ohio .

Q: | What proposals will be acted on at the Middlefield and Liberty stockholder meetings?

A: | Middlefield stockholders will be asked to (1) approve the transactions under the Reorganization Agreement, (2) approve issuance of up to 563,261 shares of Middlefield common stock in the Merger, (3) approve adjournment of the special meeting to allow additional time for proxy solicitation if there are not sufficient votes to approve the Reorganization Agreement transactions, and (4) vote on any other business properly presented.

Liberty stockholders will be asked to (1) adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, (2) approve adjournment of the annual meeting to allow additional time for proxy solicitation if there are not sufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, (3) elect twelve directors for the term expiring at the earlier of (i) completion of the Merger or (ii) the 2017 annual meeting upon the election of successors or, (4) ratify the selection of independent auditors, and (5) vote on any other business properly presented.

Q: | What do the Board of Directors of Middlefield and the Board of Directors of Liberty recommend regarding the proposals to be acted on at the stockholder meetings?

Middlefield’s board of directors believes that the Merger and other transactions under the Reorganization Agreement are in the best interests of Middlefield and its stockholders and recommends that Middlefield stockholders vote FOR the proposal to approve the transactions under the Reorganization Agreement, FOR the proposal to issue Middlefield common stock in the Merger, and FOR the proposal to adjourn the special meeting to solicit additional proxies if there are insufficient votes to approve the Reorganization Agreement transactions.

Liberty’s board of directors also determined that the Reorganization Agreement is in the best interests of Liberty and its stockholders and recommends that Liberty stockholders vote FOR the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and FOR the proposal to adjourn the annual meeting to solicit additional proxies if there are insufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. Regarding the other proposals to be presented at the annual meeting, Liberty’s board of directors recommends that stockholders vote FOR election of the identified director nominees and FOR ratification of the selection of the independent auditor.

Q: | Is my vote needed to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and to approve the other proposals?

A: | Adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement requires the affirmative vote of the holders of at least two-thirds of the shares of Liberty common stock outstanding. When Liberty’s stockholder meeting is held, if there are insufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement the meeting may be adjourned to allow solicitation of additional proxies. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to approve adjournment. All of Liberty’s directors entered into voting agreements with Middlefield as a condition to Middlefield’s agreement to the Reorganization Agreement (the “Voting Agreements”), agreeing to vote their Liberty shares in favor of adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement and in favor of the adjournment proposal. Excluding Liberty shares held by their immediate family members, Liberty’s directors collectively own 278,997 shares of Liberty common stock, or approximately 29.1% of the shares outstanding. They have the right to acquire an additional 75,989 shares, and if they do so those additional shares also are subject to the Voting Agreement. The form of Voting Agreement is an exhibit to the Reorganization Agreement attached as Annex A to this joint proxy statement/prospectus. As a holder of 23,218 shares of Liberty common stock, or 2.4%, Middlefield intends to vote in favor of adoption and approval of the Reorganization Agreement, in favor of the adjournment proposal, in favor of election of the identified director nominees, and in favor of ratifying the selection of independent accountants.

For the proposal to elect directors at Liberty’s annual meeting, directors are elected by plurality vote, which means the directors receiving the greatest number of votes are elected. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to ratify selection of Liberty’s independent auditor.

Similar to the approval standard applicable to the Liberty stockholder meeting, approval of the transactions under the Reorganization Agreement by Middlefield stockholders requires the affirmative vote of the holders of at least two-thirds of the shares of Middlefield common stock outstanding. If there are insufficient votes to approve the Reorganization Agreement transactions when Middlefield’s stockholder meeting is held, the meeting may be adjourned to allow solicitation of additional proxies. The affirmative vote of the holders of a majority of the votes cast is necessary to approve adjournment. To approve issuance of Middlefield common stock in the Merger, the affirmative vote of a majority of the votes cast is necessary. Middlefield directors did not enter into agreements regarding voting of their shares of Middlefield common stock. Collectively they own approximately 102,153 shares, or approximately 4.6% of Middlefield’s outstanding common stock, with the right to acquire 20,674 additional shares.

Q: | How do I vote?

A: | If you were the record holder of Middlefield common stock or Liberty common stock on the , 2016 record date, you may vote in person by attending your company’s meeting, and to ensure that your shares are represented at the meeting you may vote by signing and returning your company’s enclosed proxy card in the postage-paid envelope provided.

If you hold Middlefield or Liberty common stock beneficially through a broker, bank, or other nominee, please see the discussion below regarding shares held in “street name.”

Q: | What will happen if I fail to vote or if I abstain from voting?

A: | If you are a Liberty stockholder and you do not return a proxy card or vote in person at the Liberty annual meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, this will have the same effect as a vote “AGAINST” that proposal. Marking your proxy card or ballot “ABSTAIN” will have the same effect as a vote “AGAINST” the adjournment proposal and the auditor

| ratification proposal. Failure to return your proxy card or vote in person will have no effect on the adjournment proposal, the proposal to elect directors, or the proposal to ratify the auditor selection.

If you are a Middlefield stockholder and you do not return a proxy card or vote in person at the Middlefield special meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to approve the transactions under the Reorganization Agreement, this will have the same effect as a vote “AGAINST” that proposal, but failing to vote or abstaining will have no effect on the adjournment proposal or the proposal to approve issuance of shares.

Q: | How will my shares be voted if I return a signed proxy card without marking voting instructions?

A: | If you are a Liberty stockholder and you sign, date, and return a proxy card without stating how you want your shares to be voted, your shares will be voted “FOR” adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment. Similarly, your shares will be voted “FOR” election of the identified director nominees and “FOR” ratification of the auditor selection if you return a valid proxy card without giving voting instructions.

If you are a Middlefield stockholder and you sign, date, and return a proxy card without giving voting instructions, your shares will be voted “FOR” approval of the transactions under the Reorganization Agreement and “FOR” approval of the share issuance, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment.

Q: | If my shares are held in a stock brokerage account or by a bank or other nominee in “street name”, will my broker, bank, or other nominee vote shares for me?

A: | No. If you do not provide the broker, bank, or nominee (the record holder of your shares) with instructions for voting your shares, the broker, bank, or other nominee will not be able to vote on any proposal other than ratification of independent auditors. Please follow the broker, bank, or other nominee’s directions for giving voting instructions to the broker, bank, or nominee.

| • |  | if you hold Liberty shares in street name through a broker, bank, or other nominee but do not give voting instructions to the broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to adopt and approve the Reorganization Agreement and the Merger or the proposal to adjourn the meeting, which broker non-votes will have the same effect votes “AGAINST” those proposals. Failing to give voting instructions also will prevent the broker, bank, or other nominee from voting on the director election proposal, but directors nevertheless will be elected because directors are elected by a plurality; however, your broker, bank, or other nominee will be able to vote on the auditor selection proposal without voting instructions,

| • |  | if you are a Middlefield stockholder but do not give voting instructions to your broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to approve the transactions under the Reorganization Agreement, which broker non-vote will have the same effect as a vote “AGAINST” that proposal. Although failing to give voting instructions also will prevent your broker, bank, or other nominee from voting on the proposal to issue common stock or the adjournment proposal, broker non-votes on those proposals have no effect because – under Middlefield’s regulations – the proposals will be decided by a majority of votes actually cast.

Under rules of the Nasdaq Stock Market (“Nasdaq”), brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals Nasdaq considers “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Except for the auditor ratification proposal to be acted on at the Liberty stockholder meeting, Middlefield and Liberty believe the proposals to be voted on at the

stockholder meetings are “non-routine” and that brokers therefore will not be able to vote without specific voting instructions. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.

Q: | May I change my vote after submitting a proxy?

A: | Yes, but only until a vote is taken. Middlefield stockholders who hold directly, not in “street name,” may revoke a proxy at any time before a vote is taken by (x) filing a written notice of revocation with Middlefield’s Secretary, at 15985 East High Street, Middlefield, Ohio 44062-0035, (y) executing and returning another proxy card with a later date, or (z) attending the meeting and giving notice of revocation in person.

A revocation notice or a later dated proxy will not be effective unless actually received by Liberty prior to the vote.

Your attendance at the meeting will not, by itself, revoke your proxy.

If you hold shares in “street name” and gave voting instructions to the broker, bank, or nominee, you must follow the broker, bank or nominee’s directions for changing your vote.

Q: | If I do not favor adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, what are my dissenters’ rights?

A: | Under federal banking law Liberty stockholders may dissent from the Merger and elect to have the fair market value of their shares appraised, receiving payment for their shares in cash. To assert dissenters’ right of appraisal, a stockholder must comply with the provisions of federal law, which include voting against the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement or giving notice to the presiding officer in writing at or before Liberty’s meeting that the stockholder dissents. For more information see “DISSENTERS’ RIGHTS” and the copy of the applicable statutory provision attached as Annex B to this joint proxy statement/prospectus.

Q: | When will the Merger be completed?

A: | Middlefield and Liberty desire to complete the Merger by the end of 2016, but achieving that goal is contingent on obtaining stockholder approvals and applicable governmental approvals and on satisfying all other conditions precedent to the Merger.

Middlefield is a one-bank holding company. Middlefield’s principal subsidiary is The Middlefield Banking Company, an Ohio-chartered, nonmember commercial bank. Middlefield’s other subsidiary, EMORECO Inc., is an asset resolution corporation dedicated to the resolution and disposition of troubled assets of a central-Ohio bank that Middlefield acquired in 2007, specifically nonperforming loans and other real estate owned (“OREO”) held by the acquired bank as the result of borrower defaults on real estate-secured loans. That bank, Emerald Bank, operated as a separate subsidiary of Middlefield from 2007 through 2013, merging into The Middlefield Banking Company on January 20, 2014. At the end of June 2016 The Middlefield Banking Company had total assets of $758.5 million and more than 140 employees.

The Middlefield Banking Company offers a broad range of banking services, including online banking and bill payment services for individuals and online cash management services for business customers at www.middlefieldbank.com. The Middlefield Banking Company’s customers are small and medium-sized businesses, professionals, small business owners, and retail customers. Loan products include operational and working capital loans, loans to finance capital purchases, term business loans, residential construction loans, selected guaranteed or subsidized loan programs for small businesses, professional loans, residential and mortgage loans, and consumer installment loans to purchase automobiles, boats, make home improvements, and for other personal expenditures. The bank makes available customary deposit-related products and services, such as checking, savings, negotiable order of withdrawal accounts, money market accounts, time certificates of deposit, safe deposit facilities, and travelers’ checks.

The Middlefield Banking Company operates in two distinct and very competitive markets, one in the northeastern Ohio counties of Geauga, Portage, Trumbull, Ashtabula, and Lake. The other market is central Ohio, specifically the Columbus area and Franklin County, the result of the 2007 acquisition of Emerald Bank. Ohio has a high concentration of financial service firms, many of which are significantly larger institutions with greater financial resources. Savings banks, savings and loan associations, commercial banks, mortgage banking companies, credit unions, insurance companies and other financial service companies compete to make loans. Savings and loan associations, savings banks, commercial banks, and credit unions compete for deposits, but non-depository entities such as mutual funds, securities and brokerage firms, and insurance companies also compete for depositors’ funds.

The Middlefield Banking Company’s operations have historically been concentrated in the area east of Liberty’s market, in largely rural areas with a very large Amish population. The Middlefield Banking Company’s business originated in this market and was not an outgrowth of the nearby Cleveland-area or Akron-area markets. This includes Geauga County, where The Middlefield Banking Company’s business began in 1901 and where four of its ten offices are located, and northern Portage County, where two offices are located, with a seventh office in Cortland in Trumbull County, an office in Orwell in southern Ashtabula County, and two offices in central Ohio, in Franklin County. The Middlefield Banking Company’s eleventh banking office is scheduled to open in late 2016 in Sunbury, also in central Ohio, in Delaware County. It also has a loan production office in Lake County. The Middlefield Banking Company’s northeast Ohio market adjoins the market of Liberty, which is to the immediate west.

Middlefield common stock trades on the Nasdaq Capital Market under the symbol “MBCN”. Middlefield is subject to the reporting requirements under the Securities Exchange Act of 1934, filing annual, quarterly, and current reports, proxy statements, and other information with the SEC.

Liberty Bank, N.A.

25201 Chagrin Boulevard, Suite 120

Beachwood, Ohio 44122

Phone: (216) 359-5500

Liberty is a national bank established in October 1990. Liberty currently has approximately 40 employees. Liberty’s three bank offices are in Twinsburg in northern Summit County and Beachwood and Solon in eastern Cuyahoga County, Ohio. Liberty common stock is not listed on an exchange or traded over the counter. From inception, Liberty has been associated with the Akron and Cleveland business community and has sought to be a community banking resource for individuals and small business customers seeking the personalized service and local decision-making that distinguish community banks from the much larger regional and national banking institutions dominating the banking markets in Akron and Cleveland.

After the Merger, The Middlefield Banking Company will conduct through Liberty’s three bank offices the typical community banking business The Middlefield Banking Company has conducted through its offices since 1901. Both banks are community banks, and although Liberty serves the credit and deposit needs not only of local small businesses but also individuals, Liberty’s identity, its physical branch presence, and its marketing focus are more characteristic of a small business bank. The Middlefield Banking Company actively seeks to serve the lending and deposits needs not only of business customers but also individuals, for example individuals seeking home mortgage credit who do not have a preexisting commercial borrowing or deposit relationship with The Middlefield Banking Company. Middlefield believes the Merger will have the consequence of Liberty’s office locations being occupied by a community bank with a broader customer focus, with more active consumer marketing of The Middlefield Banking Company’s products and services in its new market in Cuyahoga County and Summit County.

The Reorganization Agreement (page )

If all of the Reorganization Agreement conditions are satisfied or waived, Liberty will merge into The Middlefield Banking Company, with The Middlefield Banking Company surviving. The Reorganization Agreement is Annex A to this joint proxy statement/prospectus and forms part of this joint proxy statement/prospectus. We encourage you to read the Reorganization Agreement carefully. It is the principal legal document governing the Merger. Immediately before Liberty merges into The Middlefield Banking Company, an interim bank subsidiary organized by Middlefield will merge into Liberty, with Liberty surviving momentarily before Liberty immediately thereafter merges into The Middlefield Banking Company.

What Liberty stockholders will receive in the Merger (page )

Liberty stockholders will be entitled to receive from Middlefield a combination of cash and Middlefield common stock when the Merger is completed, in addition to a special dividend of approximately $3.13 per share in cash immediately prior to the completion of the Merger. Subject to allocation procedures in the Reorganization Agreement ensuring that approximately 45% of the outstanding Liberty common stock is converted into Middlefield common stock and the remaining outstanding Liberty common stock is converted into cash, at the effective time of the Merger Liberty common stock not owned by Middlefield will be converted into the right to receive either:

| • |  | $37.96 in cash, or

| • |  | 1.1934 shares of Middlefield common stock

Liberty stockholders will own approximately 18.7% of the Middlefield common stock outstanding after the Merger. Middlefield will not issue fractional shares. Instead, a holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all Liberty common stock owned by the holder at the effective time of the Merger) will receive cash, without interest, equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

It technically is not part of the Merger consideration, but pursuant to the Reorganization Agreement, Liberty must declare a special dividend to stockholders before Merger closing. The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will not receive Merger consideration for its 23,218 Liberty shares but will be entitled to a proportionate share of the special dividend payment.

What holders of Liberty stock options and phantom shares will receive (page )

Liberty’s compensation arrangements for officers and employees include equity-based awards, including stock options and phantom awards. There are option awards outstanding for 89,561 shares, all of which are vested, including options held by Liberty’s CEO, CFO, and Chief Credit Officer to acquire a total of 79,989 shares. At the effective time of the Merger each outstanding and unexercised option to purchase Liberty common stock will be cancelled in exchange for a cash payment equal to (x) the positive difference between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise. There are also outstanding 2,000 phantom share awards made in 2013. The phantom share awards consist of the right to a cash payment equal to the positive difference between Liberty’s stock value on December 31, 2016 and the stock value on the award date, multiplied by the number of phantom shares awarded, with value being determined by Liberty’s board of directors. The total cash payment for cancellation of the options and phantom awards is estimated to be $1,147,516, of which $1,025,704 is payable to Liberty’s CEO, CFO, and Chief Credit Officer. The $41.09 figure is the sum of the $37.96 per share cash Merger consideration and the $3.13 per share special dividend.

Exchange of Liberty common stock certificates (page )

When the Merger is complete, acting as exchange agent American Stock Transfer & Trust Company, LLC will mail to Liberty stockholders transmittal materials and instructions for exchanging Liberty share certificates for Middlefield common stock to be issued by book-entry transfer.

Material U.S. federal income tax consequences (page )

The U.S. federal income tax consequences of the Merger to a Liberty stockholder will depend on the relative mix of cash and Middlefield common stock received by such Liberty stockholder. Liberty stockholders should not recognize any gain or loss for U.S. federal income tax purposes if they exchange their Liberty shares solely for shares of Middlefield common stock in the Merger, except with respect to cash received in lieu of fractional shares of Middlefield common stock. Liberty stockholders will recognize gain or loss if they exchange their Liberty shares solely for cash in the Merger. Liberty stockholders will recognize gain, but not loss, if they exchange their Liberty shares for a combination of Middlefield common stock and cash, but their taxable gain in that case will not exceed the cash they receive in the Merger. The tax consequences of the Merger to each Liberty stockholder will depend on such Liberty stockholder’s own situation. Liberty stockholders should consult with their own tax advisors for a full understanding of the tax consequences of the Merger to them. Tucker Ellis LLP has delivered a tax opinion, dated September 26, 2016, to the effect that the Merger qualifies as a “reorganization” under Section 368(a) of the Internal Revenue Code. In addition, the completion of

##### Table of Contents

the Merger is conditioned on receipt of a tax opinion from Tucker Ellis LLP, dated the closing date, to the same effect as the opinion described in the preceding sentence. The opinion will not bind the Internal Revenue Service, which could take a different view.

See “Material U.S. Federal Income Tax Consequences” for a more detailed discussion of the tax consequences of the Merger.

Interests of directors and certain executive officers of Liberty (page )

Directors and certain executive officers of Liberty have employment and other compensation agreements or economic interests that give them interests in the Merger that are somewhat different from or in addition to their interests as Liberty stockholders. These interests and agreements include:

• |  | two members of the Liberty board of directors will be appointed to Middlefield’s board of directors. These directors are Chairman, President, and CEO William A. Valerian and Director Thomas W. Bevan,

• |  | all outstanding stock options issued by Liberty to officers and employees will be cancelled in exchange for cash equal to (x) the positive difference between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise; of the $1,147,516 total payable in cancellation of options and phantom stock, $1,025,704 will be paid to President and CEO William A. Valerian, Chief Operating Officer and Chief Financial Officer Richard C. Ebner, and Senior Vice President and Chief Credit Officer Craig E. Reay. Mr. Valerian’s son holds 1,000 phantom shares, which will be cancelled in exchange for $15,200 in cash,

• |  | Liberty’s CEO William A. Valerian and CFO Richard C. Ebner have employment agreements with Liberty. The employment agreements provide that they are entitled to a payment equal to 2.5 times salary when a change in control occurs, payable in equal installments over 30 months, plus payments for the cost of life insurance, long-term disability, and medical benefits over those 30 months. The Merger will constitute a change in control under those employment agreements. Mr. Valerian’s total payments are estimated to be $904,611 and Mr. Ebner’s are estimated to be $697,317,

• |  | certain Liberty officers will receive retention bonuses to remain with Liberty through consummation of the Merger,

• |  | the Reorganization Agreement provides that Middlefield will consult with Liberty about forming a Northeast Ohio Advisory Board, which would include some of Liberty’s current directors, and

• |  | the Reorganization Agreement preserves for six years the rights of Liberty’s officers and directors to continued indemnification coverage and continued coverage under directors’ and officers’ liability insurance policies.

Each of Middlefield’s and Liberty’s board of directors was aware of these interests and considered them in approving the Reorganization Agreement and the transactions contemplated by the Reorganization Agreement. See “THE MERGER – Interests of Liberty Directors and Executive Officers in the Merger” beginning on page of this joint proxy statement/prospectus.

Dissenters’ rights of Liberty stockholders (page )

The National Bank Act gives Liberty stockholders the right to dissent from the Merger and elect to have the fair market value of their shares appraised, receiving payment for their shares in cash. To assert dissenters’ rights of appraisal, a stockholder must comply with the requirements of the National Bank Act, which include voting against the proposal to adopt and approve the Reorganization Agreement and approve the transactions

##### Table of Contents

contemplated by the Reorganization Agreement or giving notice in writing at or before Liberty’s meeting that the stockholder dissents by giving notice to the presiding officer. For more information, see “DISSENTERS’ RIGHTS” and the copy of the applicable statutory provision attached as Annex B to this joint proxy statement/prospectus.

A Liberty stockholder who has questions regarding dissenters’ rights should consult his or her legal advisers.

Differences in stockholder rights (page )

Liberty stockholders who receive Middlefield common stock will be Middlefield stockholders when the Merger is completed. As such, their rights will be governed by Middlefield’s Second Amended and Restated Articles of Incorporation and Regulations, as well as Ohio law. For a summary of significant differences between the rights of Middlefield stockholders versus the rights of Liberty stockholders, see “COMPARISON OF RIGHTS OF LIBERTY AND MIDDLEFIELD STOCKHOLDERS” beginning on page of this joint proxy statement/prospectus.

Regulatory approvals required for the Merger (page )

The Merger cannot be completed until Middlefield and Liberty receive necessary regulatory approvals, which include approval by the FDIC, the OCC, and the Ohio Division of Financial Institutions of the Merger, approval by the Ohio Division of Financial Institutions of Middlefield’s application to organize an interim bank, approval by the FDIC of the interim bank’s deposit insurance letter application, approval by the OCC of the special dividend payable to Liberty stockholders, and approval by the Ohio Division of Financial Institutions of the dividend from The Middlefield Banking Company to Middlefield that will be a source for Middlefield’s payment of the cash Merger consideration. Applications for the required approvals have been submitted but none have yet been approved. Middlefield is also seeking from the Board of Governors of the Federal Reserve System waiver of the obligation to file an application under the Bank Holding Company Act of 1956.

Conditions to the Merger (page )

As more fully described in this joint proxy statement/prospectus and in the Reorganization Agreement, completion of the Merger depends on adoption and approval of the Reorganization Agreement by Middlefield stockholders and by Liberty stockholders, receipt of required regulatory approvals, and satisfaction or waiver of other customary merger closing conditions. Middlefield and Liberty desire to complete the Merger by the end of 2016, although neither Middlefield nor Liberty can be certain as to when the regulatory approvals might be obtained. See “THE REORGANIZATION AGREEMENT – Conditions to Consummation of the Merger” beginning on page of this joint proxy statement/prospectus.

Termination; Termination Fee (page )

The Reorganization Agreement may be terminated before the effective time of the Merger, whether before or after approval by Liberty stockholders and Middlefield stockholders:

| • |  | by mutual written consent of Middlefield and Liberty,

| • |  | by either Middlefield or Liberty if the other party breaches its covenants or representations and warranties and the breach is not cured within 30 days after written notice or by its nature cannot be cured (provided the terminating party is not also in breach of its covenants or representations and warranties),

16

##### Table of Contents

| • |  | by either Middlefield or Liberty if the Merger does not occur by May 30, 2017 (or a later date the parties may agree to), unless the failure to close by that date is the result of the terminating party’s breach of covenants or representations and warranties in the Reorganization Agreement,

| • |  | by either Middlefield or Liberty if the Liberty stockholders or the Middlefield stockholders do not vote to approve the Reorganization Agreement,

| • |  | by either party if a required governmental approval is denied by final, non-appealable action, or if a governmental entity issues a final, non-appealable order, injunction, or ruling enjoining or otherwise prohibiting,

| • |  | by Middlefield if Liberty becomes subject to a formal bank regulatory enforcement action,

| • |  | by Middlefield if Liberty’s board fails to recommend adoption and approval of the Reorganization Agreement to Liberty stockholders or withdraws or adversely changes the recommendation in favor of the Reorganization Agreement, or if Liberty accepts a competing acquisition proposal, and

| • |  | by Liberty if it accepts a superior acquisition proposal, but Liberty’s termination right is conditioned on Liberty giving to Middlefield notice of the superior proposal and the opportunity to modify Middlefield’s merger proposal.

Liberty may be required to pay a termination fee of $1.65 million to Middlefield if (i) the Reorganization Agreement is terminated as described in the seventh and eighth bullet points above or (ii) if a competing acquisition proposal is made known to Liberty, Middlefield subsequently terminates the Reorganization Agreement, and Liberty enters into a definitive agreement relating to the competing acquisition proposal within one year of the termination of the Reorganization Agreement.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED CONSOLIDATED FINANCIAL DATA

The following unaudited pro forma condensed combined consolidated balance sheet as of June 30, 2016 and the unaudited pro forma condensed combined consolidated statements of income for the six months ended June 30, 2016 and for the year ended December 31, 2015 are based on the historical financial statements of Middlefield and Liberty after giving effect to the Merger. The Merger will be accounted for using the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, “Business Combinations” (“ASC 805”).

The unaudited pro forma condensed combined consolidated statements of income for the six months ended June 30, 2016 and for the year end December 31, 2015 give effect to the merger as of the beginning of all periods presented. The unaudited pro forma condensed combined consolidated balance sheet as of June 30, 2016 assumed that the merger took place on June 30, 2016.

The unaudited condensed combined consolidated balance sheet and statement of income as of and for the six months ended June 30, 2016 were derived from Middlefield’s unaudited condensed financial statements and Liberty’s unaudited condensed financial statements and as of and for the six months ended June 30, 2016. The unaudited condensed statement of income for the year ended December 31, 2015 was derived from Middlefield’s and Liberty’s audited statements of income for the year ended December 31, 2015.

The pro forma condensed combined consolidated financial statements reflect management’s best estimate of the fair value of the tangible and intangible assets acquired and liabilities assumed. As final valuations are performed, increases or decreases in the fair value of assets acquired and liabilities assumed will result in adjustments, which may be material, to the balance sheet and/or statement of income.

As required, the unaudited pro forma condensed combined consolidated financial data includes adjustments which give effect to the events that are directly attributable to the merger, expected to have a continuing impact and are factually supportable. We expect that we will incur reorganization and restructuring expenses as a result of combining our companies. We also anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses (as compared to the sum of expenses from each company while operating separately) and the opportunity to earn more revenue. The pro forma information does not take into account these expected expenses or anticipated financial benefits, and does not attempt to predict or suggest future results.

The unaudited pro forma condensed combined consolidated financial statements are provided for informational purposes only and are subject to a number of uncertainties and assumptions and do not purport to represent what the companies’ actual performance or financial position would have been had the merger occurred on the dates indicated and does not purport to indicate the financial position or results of operations as of any date or for any future period.

The unaudited pro forma condensed combined consolidated financial information is derived from and should be read in conjunction with the historical consolidated financial statements and the related notes of Middlefield and Liberty, which in the case of Middlefield are incorporated in this joint proxy statement/prospectus by reference, and in the case of Liberty are included in this joint proxy statement/prospectus. See “Where You Can Find More Information” in the forepart of this document.

The unaudited pro forma stockholders’ equity and net income are qualified by the statements set forth under this caption and should not be considered indicative of the market value of Middlefield common stock or the actual or future results of operations of Middlefield for any period. Actual results may be materially different from the pro forma information presented.

1) | Description of the Merger and Basis of Preparation

The Merger

Upon consummation of the Merger we expect to operate as a bank holding company under the name Middlefield Banc Corp. Pursuant to the Reorganization Agreement, Liberty will merge with and into The Middlefield Banking Company, a subsidiary of Middlefield, with The Middlefield Banking Company being the surviving entity and remaining Middlefield’s wholly owned subsidiary.

Basis of Presentation

The unaudited pro forma condensed combined consolidated financial statements have been prepared based on Middlefield’s and Liberty’s historical financial information. Certain disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted as permitted by SEC rules and regulations.

These unaudited pro forma condensed combined consolidated financial statements are not necessarily indicative of the results of operations that would have been achieved had the Merger actually taken place at the dates indicated and do not purport to be indicative of future financial condition or operating results.

2) | Acquisition Method

The pro forma condensed combined consolidated financial statements reflect the accounting for the transaction in accordance with ASC 805. Under the acquisition method, the purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values, with any excess of the purchase price over the estimated fair value of the identifiable net assets acquired recorded as goodwill.

Value of Liberty common stock owned by Middlefield |  |  | 915 |
Middlefield common stock to holders of Liberty common stock |  |  | 17,011 |

UNAUDITED COMPARATIVE PER SHARE DATA

The following table summarizes selected share and per share information about Middlefield and Liberty, giving effect to the Merger (known as “pro forma” information). The data in the table should be read together with the financial information and the financial statements of Middlefield and Liberty incorporated by reference or included in this joint proxy statement/prospectus. The pro forma information is presented as an illustration only, does not represent actual combined financial position per share or combined results of operations per share, and is not a forecast of the combined financial position or combined results of operations for any future period.

The information about book value per share and shares outstanding assumes that the Merger took place as of the dates presented and is based on the assumptions set forth in the preceding unaudited pro forma condensed combined consolidated balance sheets. The information about dividends and earnings per share assumes that the Merger took place as of the beginning of the periods presented and is based on the assumptions set forth in the preceding unaudited pro forma condensed combined consolidated income statements. No pro forma adjustments have been included to reflect potential effects of the Merger related to integration expenses, cost savings, or operational synergies Middlefield expects by combining the operations of Middlefield and Liberty, or to reflect the costs of combining the companies and their operations other than Merger-related expenses. It is further assumed that Middlefield will pay a cash dividend after completion of the Merger at the annual rate of $1.20 per share. The actual payment of dividends is subject to numerous factors, and no assurance can be given that Middlefield will pay dividends after the Merger or that dividends will not be reduced in the future.

RISK FACTORS

This “RISK FACTORS” section identifies some of the significant factors that make investment in Middlefield common stock speculative or risky, but it does not purport to present an exhaustive description of all significant risks. You should carefully consider the following risk factors before you decide how to vote concerning the proposals presented in this joint proxy statement/prospectus. You should also consider the other information in this joint proxy statement/prospectus, including but not limited to the section captioned “FORWARD-LOOKING STATEMENTS,” and information in the documents incorporated by reference in this joint proxy statement/prospectus. See “WHERE YOU CAN FIND MORE INFORMATION” in the forepart of this document

Because the market value of Middlefield common stock fluctuates, Liberty stockholders cannot be sure of the value of the stock portion of the Merger consideration they may receive.

Approximately 45% of the Liberty shares of common stock exchanged in the Merger will be exchanged for Middlefield common stock, and the remaining Liberty shares of common stock exchanged in the Merger (approximately 55%) will be exchanged for cash. This does not take into account the special dividend of approximately $3.0 million, to be declared before closing of the Merger. The cash portion of the Merger consideration is fixed at $37.96 per share, and the stock portion also is fixed at 1.1934 shares of Middlefield common stock for each share of Liberty common stock exchanged for stock. Changes in the price of Middlefield common stock before the Merger is completed will affect the value of the stock portion of the Merger consideration. Changes may result from many factors, including but not limited to general market and economic conditions and changes in Middlefield’s business, operations, and prospects. Therefore, when Liberty stockholders vote on the Merger they will not know the final aggregate value of the Merger consideration to be received. Liberty stockholders should obtain current sale prices for Middlefield common stock before voting at the Liberty annual meeting.

You may receive a form of consideration different from the form of consideration you elect

Under the terms of the Reorganization Agreement, stockholders of Liberty will be entitled to receive, for each share of Liberty common stock: (i) $37.96 in cash, or (ii) 1.1934 Middlefield common shares, or (iii) a combination of both. The form of consideration to be received by each Liberty stockholder is subject to reallocation in order to ensure that approximately 45% of the Merger consideration will consist of Middlefield’s common shares and 55% of the Merger consideration will consist of cash. The Reorganization Agreement contains proration and allocation methods to achieve this result. If you elect to receive all cash and the available cash is oversubscribed, then you may receive a portion of the Merger consideration in the form of Middlefield common shares. If you elect to receive all Middlefield common shares and the available common shares are oversubscribed, then you may receive a portion of the Merger consideration in cash. If you elect a combination of cash and Middlefield’s common shares, you may not receive the specific combination you request.

Middlefield could experience difficulties managing its growth and effectively integrating the operations of Liberty.

The earnings, financial condition and prospects of Middlefield after the Merger will depend in part on Middlefield’s ability to integrate successfully the operations of Liberty and continue to implement Middlefield’s business plan. Middlefield may not be able to fully achieve its strategic objectives and projected operating efficiencies. The costs or difficulties of integrating Liberty with the Middlefield organization may be greater than expected or the cost savings from anticipated economies of scale of the combined organization may be lower or take longer to realize than expected. Inherent uncertainties exist in integrating the operations of an acquired entity, and Middlefield may encounter difficulties, including but not limited to loss of key employees and customers, disruption of its ongoing business, or possible inconsistencies in standards, controls, procedures, and policies. These factors could contribute to Middlefield not fully achieving its anticipated benefits of the Merger.

The Reorganization Agreement limits Liberty’s ability to pursue alternatives to the Merger.

With limited exceptions, the Reorganization Agreement prohibits Liberty from soliciting, negotiating, or providing confidential information to any third party relating to competing proposals for acquisition of Liberty. In addition, Liberty must pay $1.65 million to Middlefield for termination of the Reorganization Agreement if (a) Middlefield terminates the Reorganization Agreement because Liberty accepts another acquisition proposal, or withdraws its recommendation or fails to recommend to the stockholders adoption of the Reorganization Agreement, or breaches the prohibition against soliciting other acquisition proposals, or (b) Liberty terminates the Reorganization Agreement with the intention of accepting an alternate, superior proposal. Liberty’s obligation to make the payment could discourage another company from making a competing proposal.

The circumstances of Liberty and Middlefield may have changed since the date of the fairness opinions obtained from Liberty’s and Middlefield’s financial advisors.

Liberty’s board of directors received an opinion dated July 27, 2016 from its financial advisor and Middlefield’s board received a July 27, 2016 opinion from its financial advisor concerning the fairness of the Merger consideration from a financial point of view. Subsequent changes in the operation and prospects of Liberty or Middlefield, changes in general market and economic conditions, and other factors that may be beyond the control of Liberty or Middlefield could significantly alter the value of Liberty or Middlefield or the price of Middlefield common stock by the time the Merger is completed. The opinions state that the Merger consideration is fair from a financial point of view on the date of the opinion, not as of the date the Merger is finally completed or as of any other date. The opinion of Liberty’s financial advisor is attached as Annex C to this joint proxy statement/prospectus. The opinion of Middlefield’s financial advisor is attached as Annex D. For a description of the opinions, see “THE MERGER – Opinion of Liberty’s Financial Advisor” on page and “THE MERGER – Opinion of Middlefield’s Financial Advisor” on page of this joint proxy statement/prospectus.

Middlefield and Liberty stockholders will have a reduced ownership and voting interest after the Merger and will exercise less influence over management of the combined organization.

The Merger will dilute the ownership position of Middlefield stockholders and result in Liberty’s stockholders having an ownership stake in the combined company that is smaller than their current 100% stake in Liberty. Upon completion of the Merger, we estimate that continuing Middlefield stockholders will own approximately 81.3% of the issued and outstanding common stock of Middlefield, while former Liberty stockholders will own approximately 18.7%. Middlefield stockholders and Liberty stockholders will therefore have less influence over the management and policies of the post-Merger organization than they currently have.

Failure to complete the Merger could adversely affect the value of Liberty common stock and future businesses and financial results of both Middlefield and Liberty.

If the Merger is not completed, the ongoing businesses of Middlefield and Liberty could be adversely affected. Middlefield and Liberty would be subject to several risks, including:

| • |  | Middlefield and Liberty will have to pay costs even if the Merger is not completed, such as legal, accounting, financial advisor, and printing fees,

| • |  | under the Reorganization Agreement, Liberty is subject to restrictions regarding the conduct of its business before completing the Merger, which could adversely affect Liberty’s ability to execute business strategies, and

| • |  | the Merger requires substantial commitments of time and resources by Middlefield and Liberty management, which would instead be devoted to other opportunities that could be beneficial to Middlefield and Liberty as independent companies.

In addition, if the Merger is not completed, Middlefield and Liberty may experience negative reactions from their respective customers and employees. Employees could resign and obtain other employment as a result of the potential Merger or failure to complete the Merger. Middlefield or Liberty also could be subject to litigation related to failure to complete the Merger.

The Middlefield common stock received by Liberty stockholders upon completion of the Merger will have different rights from Liberty shares.

When the Merger is completed, Liberty stockholders receiving the stock form of Merger consideration will no longer be stockholders of Liberty but will instead be Middlefield stockholders, with rights governed by the Ohio Revised Code and Middlefield’s articles of incorporation and regulations, which are in some respects materially different from the terms of Liberty’s Bylaws and Amended and Restated Articles of Association. See “COMPARISON OF RIGHTS OF LIBERTY AND MIDDLEFIELD STOCKHOLDERS” on page of this joint proxy statement/prospectus.

Liberty directors and certain of Liberty’s officers have interests that are different from, or in addition to, interests of Liberty’s stockholders generally

The directors and certain executive officers of Liberty have interests in the Merger that are different from, or in addition to, the interests of Liberty stockholders generally. These interests include covenants in the Reorganization Agreement providing for the election of two current Liberty directors (Messrs. Valerian and Bevan), to the Middlefield board of directors immediately after the Merger is consummated, indemnification and insurance for directors and officers of Liberty for events occurring before the Merger as well as the possible formation of a Northeast Ohio Advisory Board that would include some current Liberty directors. In addition, the Reorganization Agreement provides for retention payments to be made to certain officers and the payment of amounts due under employment agreements with Liberty’s Chairman and President and with its Chief Operating Officer and Chief Financial Officer.

Liberty will be subject to business uncertainties and contractual restrictions while the Merger is pending.

Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on Liberty and consequently on Middlefield. These uncertainties may impair Liberty’s ability to attract, retain and motivate key personnel until the Merger is consummated, and could cause customers and others that deal with Liberty to seek to change existing business relationships with Liberty. Retention of certain employees may be challenging during the pendency of the Merger, as certain employees may experience uncertainty about their future roles with Middlefield. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Middlefield, Middlefield’s business following the Merger could be harmed. In addition, the Reorganization Agreement restricts Liberty from making certain acquisitions and taking other specified actions until the Merger occurs without the consent of Middlefield. These restrictions may prevent Liberty from pursuing attractive business opportunities that may arise prior to the completion of the Merger. Please see the section entitled “THE REORGANIZATION AGREEMENT – Covenants and Agreements” beginning on page of this proxy statement/prospectus for a description of the restrictive covenants to which Liberty is subject under the Reorganization Agreement.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or cannot be met.

Before the transactions contemplated in the Reorganization Agreement may be completed, various approvals must be obtained from the bank regulatory and other governmental authorities. In determining whether to grant these approvals, the regulators consider a variety of factors, including the regulatory standing of each party and the factors described under “THE MERGER – Regulatory Approvals Required” starting on page of this joint proxy statement/prospectus. An adverse development in either party’s regulatory standing or these factors could result in an inability to obtain one or more approvals or delay their receipt. These governmental

30

##### Table of Contents

entities may impose conditions, limitations or costs, or place restrictions on the conduct of Middlefield after the closing as a condition to the granting of such approvals or require changes to the terms of the Merger. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying completion of the Merger or of imposing additional costs or limitations on Middlefield following the Merger, any of which might have an adverse effect on Middlefield following the Merger. The regulatory approvals may not be received, may not be received in a timely fashion, and may contain conditions on the completion of the Merger that adversely affect the surviving corporation’s business following the closing, or which are not anticipated or cannot be met.

Completion of the Merger is subject to many conditions and if these conditions are not satisfied or waived, the Merger will not be completed.

The obligation of Middlefield and Liberty to complete the Merger is subject to the fulfillment or written waiver of many conditions, including approval by the requisite vote of Middlefield and Liberty stockholders, receipt of regulatory approvals, absence of orders prohibiting completion of the Merger, effectiveness of the registration statement of which this document is a part, approval for Nasdaq listing of the Middlefield shares to be issued, continued accuracy of the representations and warranties of the parties, and performance by the parties of covenants and agreements. See “THE REORGANIZATION AGREEMENT – Conditions to the Merger” on page of this joint proxy statement/prospectus. These conditions to the consummation of the Merger might not be fulfilled, and the Merger therefore might not be completed. If the Merger is not completed by May 30, 2017 (or a later date the parties may agree to), either Middlefield or Liberty could choose not to proceed with the Merger. The parties also could mutually decide to terminate the Reorganization Agreement at any time, before or after approval by stockholders. In addition, Middlefield or Liberty could elect to terminate the Reorganization Agreement in other circumstances. See “THE REORGANIZATION AGREEMENT – Termination; Termination Fee” on page of this joint proxy statement/prospectus for details or refer to Article 10 of the Reorganization Agreement attached as Annex A.

Risks Related to Owning Middlefield Stock.

You should read and consider risk factors specific to Middlefield’s business that will also affect the combined company after the Merger, described in Middlefield’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, all of which are filed by Middlefield with the SEC and incorporated by reference into this document.

THE ANNUAL MEETING OF LIBERTY STOCKHOLDERS

Time, Date and Place

This joint proxy statement/prospectus is provided to Liberty stockholders by Liberty’s board of directors for solicitation of proxies to be used at the annual meeting of stockholders. The annual meeting will be held at a.m. local time on , 2016 at , Ohio , including any adjournment. This joint proxy statement/prospectus is also being furnished by Middlefield to Liberty stockholders as a prospectus for issuance of Middlefield common stock in the proposed Merger.

Matters to be Considered

Liberty stockholders will be asked at the annual meeting to consider and vote upon proposals to –

| • |  | adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement,

| • |  | adjourn the meeting to allow solicitation of additional proxies if there are insufficient votes at the meeting to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement,

| • |  | elect twelve directors to serve until the earlier of (i) completion of the Merger or (ii) Liberty’s 2017 annual meeting upon the election of successors,

| • |  | ratify the appointment of Maloney + Novotny LLC as independent public accountants for the fiscal year ending December 31, 2016, and

| • |  | transact any other business properly presented at the annual meeting or at any adjournment. Liberty’s board of directors is not aware of any other business to be transacted at the meeting.

Liberty’s board of directors believes the Merger with Middlefield is in the best interests of Liberty stockholders. The board recommends that you vote (1) “FOR” adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, (2) if the adjournment proposal is presented for a vote, “FOR” adjournment to allow additional proxy solicitation, (3) “FOR” election of the identified director nominees, and (4) “FOR” ratification of the selection of independent accountants.

Record Date; Shares Outstanding and Entitled to Vote

, 2016 is the record date for determining Liberty stockholders entitled to vote at the annual meeting. Only holders of Liberty common stock at the close of business on the record date are entitled to vote at the meeting. As of the close of business on the record date there were shares of Liberty common stock outstanding and entitled to vote. Liberty common stock is held of record by 272 stockholders. Each share of Liberty common stock entitles the holder to one vote on all matters properly presented at the meeting. Stockholders are not entitled to vote cumulatively in the election of directors.

Votes Required; Quorum

Adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement requires the affirmative vote of the holders of at least two-thirds of the shares of Liberty common stock outstanding. When the stockholder meeting is held, if there are insufficient votes to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement the meeting may be adjourned to allow solicitation of additional proxies. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to approve adjournment. For the proposal to elect directors, directors are elected by plurality vote,

34

##### Table of Contents

which means the director receiving the greatest number of votes are elected. The affirmative vote of the holders of a majority of the shares represented at the meeting in person or by proxy and entitled to vote is necessary to ratify selection of Liberty’s independent accountants.

If you are a Liberty stockholder and you do not return a proxy card or vote in person at the Liberty annual meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, this will have the same effect as a vote “AGAINST” the proposal. Marking your proxy card or ballot “ABSTAIN” will have the same effect as a vote “AGAINST” the adjournment proposal and the auditor ratification proposal. Failure to return your proxy card or vote in person will have no effect on the adjournment proposal, the proposal to elect directors, or the proposal to ratify the auditor selection.

If you hold your Liberty stock in “street name” through a broker, bank, or other nominee, you must provide your broker, bank, or nominee with voting instructions. Under Nasdaq rules, brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals Nasdaq considers “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Broker non-votes occur when a broker or nominee does not receive voting instructions from the beneficial owner. Except for the auditor ratification proposal, Liberty believes the proposals to be voted on at Liberty’s annual meeting are “non-routine” and that brokers therefore will not be able to vote on those proposals without specific voting instructions. Therefore, if you hold Liberty shares in street name but do not give voting instructions to your broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, the proposal to adjourn the meeting, or the proposal to elect directors.

Broker non-votes will have the same effect as votes “AGAINST” the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement and the proposal to adjourn the meeting. Failing to give voting instructions also will prevent the broker, bank, or other nominee from voting on the director election proposal, but directors nevertheless will be elected because directors are elected by a plurality. Your broker, bank, or other nominee will be able to vote on the auditor selection proposal without voting instructions. Your broker, bank, or other nominee will provide you with a proxy card and directions for giving voting instructions. Please follow the broker, bank, or other nominee’s directions to give voting instructions.

A quorum will exist at Liberty’s annual meeting if a majority of the outstanding common stock is represented in person or by proxy. A quorum must be present in person or by proxy at the meeting before any action other than adjournment can be taken. A properly executed proxy card marked “ABSTAIN” will be counted for purposes of determining whether a quorum is present.

All of Liberty’s directors agreed to vote their Liberty shares in favor of adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, in favor of the adjournment proposal and in favor of entering into Voting Agreements with Middlefield as a condition to Middlefield’s agreement to enter into the Reorganization Agreement. Excluding Liberty shares held by their immediate family members, Liberty’s directors collectively own 278,997 shares of Liberty common stock, or approximately 29.1% of the shares outstanding. They have the right to acquire an additional 75,989 shares, and if they do so those additional shares also are subject to the Voting Agreement. As a holder of 23,218 shares of Liberty common stock, or 2.4%, Middlefield intends to vote in favor of adoption and approval of the Reorganization Agreement and approval of the transactions contemplated therein, in favor of the adjournment proposal if applicable, in favor of electing the director nominees identified in this joint proxy statement/prospectus, and in favor of ratifying the selection of independent auditors.

Solicitation and Revocation of Proxies

A proxy card accompanies this joint proxy statement/prospectus. If you are a Liberty stockholder your proxy is being solicited by Liberty’s board of directors. Regardless of whether you attend the annual meeting, the Liberty board of directors urges you to return your properly executed proxy card as soon as possible. If you return your properly executed proxy card before the meeting and do not revoke it, the shares of Liberty common stock represented by the proxy card will be voted at the annual meeting or adjournment.

The Liberty common stock will be voted as specified on the proxy card. If you are a Liberty stockholder and you sign, date, and return a proxy card without stating how you want your shares to be voted, your shares will be voted “FOR” adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment. Similarly, your shares will be voted “FOR” election of the identified director nominees and “FOR” ratification of the auditor selection if you return a valid proxy card without giving voting instructions. Although Liberty’s board currently does not expect any other proposals to be presented at the meeting, if any other proposals are properly presented the Liberty common stock represented by properly executed proxy cards will, to the extent permitted by applicable law, be voted in the discretion of the persons named in the proxy card in accordance with their best judgment.

If you return a properly executed proxy card, you may revoke it at any time before a vote is taken at the meeting by:

| • |  | filing a written notice of revocation with Richard C. Ebner, Secretary of Liberty, at 25201 Chagrin Boulevard, Suite 120, Beachwood, Ohio 44122,

| • |  | executing and returning another proxy card with a later date, or

| • |  | attending the meeting and giving notice of revocation in person.

Attending Liberty’s annual meeting will not, by itself, revoke your proxy. If you instructed your broker, bank, or other nominee to vote your shares but you wish to change or revoke those voting instructions, you must follow your broker, bank, or other nominee’s directions for changing or revoking your vote.

Liberty will bear its own cost of solicitation of proxies. Proxies will be solicited by mail and may also be solicited by personal contact, telephone, facsimile, or electronic mail by directors, officers, and employees, none of whom will receive additional compensation for their solicitation activities. Liberty will pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations, and other custodians, nominees, and fiduciaries who are record holders of Liberty common stock not beneficially owned by them for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to and obtaining voting instructions from the beneficial owners of Liberty common stock.

PROPOSALS SUBMITTED TO LIBERTY STOCKHOLDERS

Director Election Proposal

The board of directors of Liberty, elected by Liberty’s stockholders, oversees the business and management of Liberty. Members of the board monitor and evaluate Liberty’s business performance through regular communication with the CEO and senior management, and by attending board and board committee meetings. The board is committed to sound and effective corporate governance policies and high ethical standards. Under Liberty’s Amended and Restated Articles of Association and By-Laws, the board must consist of at least 5 directors, but may not exceed 25 directors. The By-Laws provide that the number of directors constituting the board may be changed from time to time, either pursuant to a resolution adopted by a majority of the board, or pursuant to the affirmative vote of a majority of the stockholders present in person or by proxy at any meeting of stockholders which has as one of its purposes the election of directors, provided that a quorum is present. The board has fixed the number of authorized directors at thirteen (13). There is currently one vacancy on the board. The board will fill that vacancy when a suitable candidate is identified. Twelve seats on the board are currently filled by the individuals identified as directors in the table below, each of whom has been nominated for re-election by action of the board. Each such nominee has consented to being named in this proxy statement and has agreed to serve if elected.

Term of Office

Each director serves for a term ending at the next Annual Meeting of Stockholders following his or her appointment or election as a director, upon the election of successors. The term of each of Liberty’s twelve current directors expires at the annual meeting, upon the election of their successors. The board has nominated the twelve current directors for re-election to the board for a term ending upon the earliest of the completion of the Merger, the 2017 annual meeting upon the election of successors, or until he resigns or is otherwise removed and his successor is duly elected and qualified.

Nominations of Directors

Upon the recommendation of the Corporate Governance/Nominating Committee, the board has nominated the twelve individuals identified below for election as directors. The board believes that the qualifications and experience of the 2016 director nominees will contribute to an effective and well-functioning board. The board and the Corporate Governance/Nominating Committee believe that, individually and as a whole, the directors possess the necessary qualifications to provide effective oversight of Liberty’s business and quality advice and counsel to Liberty’s management.

Nominations of candidates for election as directors at the meeting are governed by Liberty’s By-Laws. The By-Laws provide that such nominations may be made either by the board or by any stockholders entitled to vote at a meeting of stockholders at which directors are elected. The By-Laws require that such nominations, if not made by or on behalf of the board, be made in writing and delivered in person or mailed to Liberty’s Secretary and to the OCC in Washington, D.C., not less than 14 days nor more than 50 days prior to such meeting. However, if less than 21 days’ notice of such meeting is given to stockholders, such nominations shall be mailed or delivered to the Secretary and to the OCC not later than the close of business on the seventh day following the day on which the notice of meeting was given to stockholders. Notice of the meeting of Liberty’s stockholders is deemed to be given on the date on which such notice is deposited in the United States mail. For the purpose of the herein notice with respect to the meeting, such date is , 2016.

Liberty’s By-Laws further require that nominations for election as director, if not made by or on behalf of the board, set forth the name, address, and the number and class of Liberty common stock owned by the nominating stockholder, and must include all information relating to the proposed nominee that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, including the proposed nominee’s written consent to serve as a director if elected.

Liberty’s By-Laws provide that if the Chairman of the meeting determines that the nomination of any candidate for election as a director was not made in accordance with the By-Laws, then the Chairman may order that such nomination, and all votes cast for the election of such candidate, be disregarded.

As provided by the By-Laws of Liberty, a majority of the board then in office may fill a vacancy on the board.

Independent Directors

A majority of the directors and all of the members of the Audit Committee, the Corporate Governance/Nominating Committee, and the Compensation Committee are “independent,” as such term is defined in Rule 5605(a)(2) of the Nasdaq listing standards. Under Nasdaq Rule 5605(a)(2), “independent director” means a person other than an executive officer or employee of Liberty or any other individual having a relationship which, in the opinion of Liberty’s board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. For purposes of this rule, “family member” means a person’s spouse, parents, children and siblings, whether by blood, marriage or adoption, or anyone residing in such person’s home. Under the Nasdaq rule, the following persons shall not be considered independent:

(A) a director who is, or at any time during the past three years was, employed by Liberty;

(B) a director who accepted or who has a family member who accepted any compensation from Liberty in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence, other than the following:

(i) compensation for board or board committee service;

(ii) compensation paid to a family member who is an employee (other than an Executive Officer) of Liberty; or

(iii) benefits under a tax-qualified retirement plan, or non-discretionary compensation.

Provided, however, that in addition to the requirements contained in this paragraph (B), Audit Committee members are also subject to additional, more stringent requirements under Nasdaq Rule 5605(c)(2).

(C) a director who is a family member of an individual who is, or at any time during the past three years was, employed by the company as an executive officer;

(D) a director who is, or has a family member who is, a partner in, or a controlling shareholder or an executive officer of, any organization to which Liberty made, or from which Liberty received, payments for property or services in the current or any of the past three fiscal years that exceed 5% of the recipient’s consolidated gross revenues for that year, or $200,000, whichever is more, other than the following:

(i) payments arising solely from investments in Liberty’s securities; or

(ii) payments under non-discretionary charitable contribution matching programs.

(E) a director of Liberty who is, or has a family member who is, employed as an executive officer of another entity where at any time during the past three years any of the executive officers of Liberty serve on the compensation committee of such other entity; or

40

##### Table of Contents

(F) a director who is, or has a family member who is, a current partner of Liberty’s outside auditor, or was a partner or employee of Liberty’s outside auditor who worked on Liberty’s audit at any time during any of the past three years.

The board has determined that all of the current directors, except for Messrs. Valerian and Ebner, who are executive officers of Liberty, are independent directors within the meaning of the foregoing requirements.

Executive Session

The non-management or independent directors of the board meet periodically in executive session without the directors who are executive officers.

Audit Committee

The Audit Committee of Liberty is required to have at least three members, each of whom must comply with the independence and other standards for audit committee members under Nasdaq Rule 5605(c)(2) and Rule 10A-3(b)(1) under the Act. The current members of the Audit Committee of the Bank are Michael A. Carlin, Dominic M. D’Amore, Jr. (Chair), Ralph R. Razinger, Thomas A. Reitan and Daniel D. Smith.

Each Audit Committee member must: (i) be “independent” as defined under the Nasdaq director independence rules set forth above; (ii) meet the criteria for independence set forth in Rule 10A-3(b)(1) under the Act (subject to the exemptions provided in Rule 10A-3(c) under the Act); (iii) not have participated in the preparation of the financial statements of Liberty or any current subsidiary of Liberty at any time during the past three years; and (iv) be able to read and understand fundamental financial statements, including Liberty’s balance sheet, income statement, and cash flow statement. Furthermore, at least one member of the Audit Committee has, and will continue to have, past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual’s financial sophistication, including being or having been a chief executive officer, chief financial officer or other senior officer with financial oversight responsibilities. Liberty has determined that Audit Committee members Michael A. Carlin and Dominic M. D’Amore, Jr. meet these requirements.

The board met twelve (12) times during 2015. Each director attended at least 75% of the meetings of the board.

From time to time, Liberty extends credit to its directors and executive officers for business and personal uses. All extensions of credit to directors and executive officers are made in the ordinary course of Liberty’s business and on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other borrowers involving similar credit risk. Such credit extensions are made after a determination by the Bank that they do not involve more than the normal risk of collectability or present other unfavorable features.

Liberty’s board of directors recommends voting “FOR” election of the identified director nominees.

Liberty Merger Proposal

As discussed throughout this joint proxy statement/prospectus, Liberty is asking stockholders to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. Liberty stockholders should carefully read this document in its entirety for more detailed information regarding the Reorganization Agreement and the Merger. In particular, stockholders are directed to the copy of the Reorganization Agreement attached as Annex A to this joint proxy statement/prospectus.

Liberty’s board of directors recommends voting “FOR” approval and adoption of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement.

Liberty Adjournment Proposal

If there are insufficient votes at the time of the Liberty annual meeting to approve and adopt the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, the meeting may be adjourned to another time or place to allow additional time for proxy solicitations. If the number of shares of Liberty common stock voting in favor is insufficient to approve and adopt the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement, Liberty intends to move for adjournment to enable the Liberty board of directors to solicit additional proxies for approval. If that occurs, Liberty will ask the Liberty stockholders to vote upon the adjournment proposal (but not the Merger proposal) and will also ask stockholders to vote on the director election proposal and auditor ratification proposal. Liberty is asking stockholders to authorize the proxy holder to vote in favor of adjournment of the Liberty annual meeting to another time and place for the purpose of soliciting additional proxies. If the adjournment proposal is approved, proxies will remain valid if not revoked and Liberty could use the additional time to solicit additional proxies, including the solicitation of proxies from Liberty stockholders who have previously voted.

Auditor Ratification Proposal

The Audit Committee of Liberty’s board appointed Maloney + Novotny LLC, Certified Public Accountants, to serve as the Bank’s independent auditors for its fiscal year ending December 31, 2016. The board is seeking stockholder ratification of the Audit Committee’s appointment of Maloney + Novotny LLC. Representatives of Maloney + Novotny LLC are expected to attend the annual meeting to respond to appropriate questions, and will have an opportunity to make a statement if they desire. If the appointment of Maloney + Novotny LLC is not ratified by the stockholders, the Audit Committee may appoint another independent accounting firm or may decide to maintain the appointment of Maloney + Novotny LLC. Notwithstanding the selection and ratification, the Audit Committee, in its discretion, may direct the appointment of a new independent public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of Liberty and its stockholders.

The affirmative vote of a majority of the voting power of the common stock present is necessary for ratification of the selection of independent auditors.

Liberty’s board of directors recommends voting “FOR” ratification of the selection of Maloney + Novotny LLC as independent auditors.

THE SPECIAL MEETING OF MIDDLEFIELD STOCKHOLDERS

Time, Date and Place

This joint proxy statement/prospectus is provided to Middlefield stockholders by Middlefield’s board of directors for solicitation of proxies to be used at the special meeting of stockholders. The special meeting will be held at a.m. local time on , 2016 at , Ohio , including any adjournment.

Matters to be Considered

Middlefield stockholders will be asked at the special meeting to consider and vote upon proposals to –

| • |  | adopt and approve the Reorganization Agreement,

| • |  | approve the issuance of up to 563,261 shares of Middlefield common stock in the Merger,

| • |  | adjourn the meeting to allow solicitation of additional proxies if there are insufficient votes to adopt and approve the Reorganization Agreement,

| • |  | transact any other business properly presented at the special meeting or at any adjournment. Middlefield’s board of directors is not aware of any other business to be transacted at the meeting.

Middlefield’s board of directors believes the Merger is in the best interests of Middlefield stockholders and recommends that you vote (1) “FOR” the Reorganization Agreement, (2) “FOR” issuance of common stock, and (3) ) if the adjournment proposal is presented for a vote, “FOR” adjournment.

Record Date; Shares Outstanding and Entitled to Vote

The board of directors fixed the close of business on , 2016 as the record date for determining Middlefield stockholders entitled to vote at the special meeting. As of the close of business on the record date there were shares of Middlefield common stock outstanding and entitled to vote at the special meeting. Middlefield common stock is held of record by approximately stockholders. Each share of Middlefield common stock entitles the holder to one vote on all proposals at the special meeting.

Votes Required; Quorum

Under the Ohio General Corporation Law and Middlefield’s Second Amended and Restated Articles of Incorporation, adoption and approval of the Reorganization Agreement requires the affirmative vote of the holders of at least two-thirds of Middlefield’s outstanding common stock. Under Nasdaq rules, approval of the issuance of Middlefield common stock requires the affirmative vote of the holders of a majority of votes cast on the proposal. Under Middlefield’s regulations, approval of adjournment requires the affirmative vote of the holders of a majority of the votes cast on the proposal. On the record date Middlefield directors owned a total of 102,153 shares of Middlefield common stock, or approximately 4.6%.

If you are a Middlefield stockholder and you do not return a proxy card or vote in person at the Middlefield special meeting or if you mark the proxy card or ballot “ABSTAIN” for the proposal to adopt and approve the Reorganization Agreement, this will have the same effect as a vote “AGAINST” that proposal. Failing to vote or abstaining will have no effect on the adjournment proposal or the proposal to approve issuance of shares.

If you hold your Middlefield stock in “street name” through a broker, bank, or other nominee, please provide your broker, bank, or nominee (the record holder of your common stock) with voting instructions. Under Nasdaq rules, brokers who hold shares in “street name” for a beneficial owner are allowed to vote in their

44

##### Table of Contents

discretion on “routine” proposals, even without voting instructions from beneficial owners. For proposals Nasdaq considers “non-routine,” however, brokers are not allowed to exercise voting discretion and cannot vote on those non-routine proposals unless the beneficial owner gives specific voting instructions. Broker non-votes occur when a broker or nominee does not receive voting instructions from the beneficial owner. Middlefield believes the proposals to be voted on at the special meeting are “non-routine” and that brokers therefore will not be able to vote on those proposals without specific voting instructions. Therefore, if you hold Middlefield stock in street name but do not give voting instructions to your broker, bank, or other nominee, the broker, bank, or other nominee may not vote your shares on the proposal to adopt and approve the Reorganization Agreement, the proposal to approve share issuance, or the proposal to adjourn the meeting.

Broker non-votes on the proposal to adopt and approve the Reorganization Agreement will have the same effect as votes “AGAINST” that proposal. Failing to give voting instructions also will prevent your broker, bank, or other nominee from voting on the proposal to issue common stock and the adjournment proposal, but under Middlefield’s regulations broker non-votes on those proposals have no effect because the proposals are decided by a majority of votes actually cast. Your broker, bank, or other nominee will provide you with a proxy card and directions for giving voting instructions. Please follow the broker, bank, or other nominee’s directions to give voting instructions.

A quorum will exist at Middlefield’s special meeting if a majority of the outstanding common stock is represented in person or by proxy. A quorum must be present in person or by proxy at the meeting before any action other than adjournment can be taken. A properly executed proxy card marked “ABSTAIN” will be counted for purposes of determining whether a quorum is present.

Solicitation and Revocation of Proxies

A proxy card accompanies this joint proxy statement/prospectus. If you are a Middlefield stockholder your proxy is solicited by Middlefield’s board of directors. Regardless of whether you attend the special meeting, the Middlefield board urges you to return your properly executed proxy card as soon as possible. If you return a properly executed proxy card before the special meeting and do not revoke it, the Middlefield common stock represented by the proxy card will be voted at the special meeting or adjournment. The common stock will be voted as specified on the proxy card.

If you are a Middlefield stockholder and you sign, date, and return a proxy card but do not specify how your shares are to be voted, your shares will be voted “FOR” adoption and approval of the Reorganization Agreement, “FOR” issuance of common stock in the Merger, and if adjournment of the meeting is necessary to allow time for solicitation of additional proxies your shares will be voted “FOR” adjournment. Although Middlefield’s board currently does not expect any other proposals to be presented at Middlefield’s special meeting, if any other proposals are properly presented the common stock represented by properly executed proxy cards will, to the extent permitted by applicable law, be voted in the discretion of the persons named in the proxy card in accordance with their best judgment.

If you return a properly executed proxy card, you may revoke it at any time before a vote is taken at the meeting by:

| • |  | filing a written notice of revocation with Ms. Kathleen M. Johnson, Secretary, Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062,

| • |  | executing and returning another proxy card with a later date, or

| • |  | attending the meeting and giving notice of revocation in person.

Attending Middlefield’s special meeting will not, by itself, revoke your proxy. If you instructed your broker, bank, or other nominee to vote your shares but you wish to change or revoke those voting instructions, you must follow your broker, bank, or other nominee’s directions for changing or revoking your vote.

##### Table of Contents

Middlefield will bear its own cost of solicitation of proxies. Proxies will be solicited by mail and may also be solicited by personal contact, telephone, facsimile, or electronic mail by directors, officers, and employees, none of whom will receive additional compensation for their solicitation activities. Middlefield has also engaged D.F. King & Co., a proxy soliciting firm, to assist in the solicitation of proxies for a fee of $15,000 and reimbursement of reasonable out-of-pocket expenses. Middlefield will pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations, and other custodians, nominees, and fiduciaries who are record holders of Middlefield common stock not beneficially owned by them for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to and obtaining proxies from the beneficial owners of Middlefield common stock.

PROPOSALS SUBMITTED TO MIDDLEFIELD STOCKHOLDERS

Middlefield Merger Proposal

As discussed throughout this joint proxy statement/prospectus, Middlefield is asking its stockholders to adopt and approve the Reorganization Agreement. Middlefield stockholders should read this document carefully in its entirety for more detailed information regarding the Reorganization Agreement and the Merger. In particular, stockholders are directed to the copy of the Reorganization Agreement attached as Annex A to this joint proxy statement/prospectus.

Middlefield’s board of directors recommends voting “FOR” approval and adoption of the Reorganization Agreement.

Middlefield Proposal to Approve Issuance of Common Stock

Middlefield is also asking stockholders to consider and vote on the proposal to issue up to 563,261 shares of Middlefield common stock in the Merger. A company with Nasdaq-listed stock is required by Nasdaq rules to obtain stockholder approval if a proposed stock issuance equals or exceeds 20% of the number of shares outstanding before the issuance. The number of shares to be issued by Middlefield in the Merger is approximately 23% of the number of shares outstanding, and for this reason Nasdaq rules require Middlefield to seek stockholder approval. If Middlefield stockholders do not approve the common stock issuance, Middlefield will not be able to complete the Merger.

Middlefield’s board of directors recommends voting “FOR” approval of the issuance of up to 563,261 shares of Middlefield common stock in the Merger.

Middlefield Adjournment Proposal

If there are insufficient votes at the time of Middlefield’s special meeting to approve and adopt the Reorganization Agreement, the meeting may be adjourned to another time or place to allow additional time for proxy solicitations. If the number of shares of Middlefield common stock voting in favor is insufficient to approve and adopt the Reorganization Agreement, Middlefield intends to move for adjournment to enable Middlefield’s board to solicit additional proxies for approval. If that occurs, Middlefield will ask stockholders to vote upon adjournment but not the merger proposal or the proposal to approve share issuance. Middlefield is asking stockholders to authorize the proxy holder to vote in favor of adjournment of the Middlefield special meeting to another time and place for the purpose of allowing additional proxy solicitation. If the adjournment proposal is approved, proxies will remain valid if not revoked and Middlefield could use the additional time to solicit additional proxies, including solicitation of proxies from Middlefield stockholders who have previously voted.

Middlefield’s board of directors recommends voting “FOR” the adjournment proposal.

DISSENTERS’ RIGHTS

Liberty stockholders are entitled to exercise dissenters’ rights of appraisal under the National Bank Act, 12 U.S.C. §215. A copy of the dissenters’ rights provisions of 12 U.S.C. 215 is attached as Annex B to this joint proxy statement/prospectus. Under these provisions of federal law, Liberty stockholders may dissent from the Merger and elect to have the fair market value of their shares appraised, receiving payment of the appraised value in cash. To assert dissenters’ right of appraisal, a stockholder must vote against the proposal to adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement or give notice in writing at or before Liberty’s meeting that the stockholder dissents, giving such notice to the presiding officer. The dissenting stockholder must make a written request to Middlefield for payment of the appraised value of his or her shares at any time before 30 days after Merger consummation, accompanied by surrender of his or her stock certificates.

The value of a dissenter’s Liberty shares will be determined by a committee of three persons, including one selected by a majority vote of the dissenting stockholders, one selected by the directors of The Middlefield Banking Company, and the third by the two so chosen. The valuation agreed upon by any two of these three appraisers governs, but if the value fixed by the appraisers is not satisfactory to a dissenting stockholder, the stockholder may within five days after being notified of the appraised value of his or her shares appeal to the Office of the Comptroller of the Currency (OCC), which will cause a reappraisal to be made. The OCC’s reappraisal will be final and binding. If within 90 days after the effective date of the Merger one or more of the appraisers is not selected or the appraisers fail to determine the value of the dissenting shares, upon written request of any interested party the OCC will cause an appraisal to be made, which will be final and binding on all parties. The expenses of the OCC in making the appraisal or reappraisal will be paid by The Middlefield Banking Company.

This summary of dissenters’ rights is qualified in its entirety by reference to the statutory provisions of 12 U.S.C. 215, paragraphs (b) through (d), reproduced in Annex B. Failure by a Liberty stockholder to follow the required steps for perfecting rights as a dissenting stockholder will result in a loss of those rights. Stockholders’ notice of intent to demand appraisal of and payment for their shares should be sent to: William A. Valerian, Chairman, President and Chief Executive Officer, Liberty Bank, N.A., 25201 Chagrin Boulevard, Suite 120, Beachwood, Ohio 44122. When the Merger is completed, before the 30th day after completion of the Merger stockholders who have properly asserted dissenters’ rights should request in writing to Middlefield that it pay the appraised value of their shares, surrendering their stock certificates to Middlefield at that time. The written request after the Merger should be sent to: Thomas G. Caldwell, President and Chief Executive Officer, The Middlefield Banking Company, 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.

You are encouraged to read the Reorganization Agreement carefully. The Reorganization Agreement is the principal legal document governing the Merger.

Background of the Merger

Retained by Liberty as financial advisor for a possible strategic transaction, in March 2016 Boenning & Scattergood, Inc. (“Boenning”) invited financial organizations – including Middlefield – to review a confidential information memorandum concerning Liberty and to submit an initial acquisition bid, with an April 18, 2016 deadline for non-binding indications of interest. Executing the March 21, 2016 confidentiality agreement, Middlefield received a copy of Boenning’s confidential information memorandum. After reviewing the confidential information memorandum, Middlefield management declined to submit a bid. Beginning with the financial crisis of 2007 and 2008 merger and acquisition activity for financial institutions remained for many years at greatly reduced levels by comparison to the ten-year period ended in 2006, with much of the post-crisis activity involving acquisitions of problem institutions or sales of control to private equity firms. But by the end of 2015 the pace of healthy financial institution acquisitions was again accelerating. This was one of the factors that led Middlefield management to initially decline submitting a bid for Liberty, believing a very competitive bidding process would lead to deal terms outside the range sanctioned by Middlefield’s internal policies.

In the first half of 2016 Middlefield management’s attention was focused on raising additional equity in a private offering. Middlefield engaged Boenning to assist with the private equity offering, entering into a letter agreement with Boenning & Scattergood on February 12, 2016, later superseded by an April 27, 2016 Placement Agency Agreement. Under the letter agreement and Placement Agency Agreement, Boenning acted as Middlefield’s exclusive placement agent. A private placement to accredited investors only of no more than 20% of Middlefield’s common stock outstanding, the private offering began on or about May 2, 2016 and ended June 30, 2016. Middlefield sold to 29 accredited investors a total of 360,815 shares at $33 per share, or approximately 19% of the shares outstanding before the private placement and 16% of the shares outstanding after. Middlefield’s net proceeds of the private offering were $11.3 million, after commissions of approximately $577,000 payable to Boenning and reimbursement of $20,245 of Boenning expenses. With the proceeds of the private placement Middlefield repaid borrowings, including a $3.0 million line of credit from Liberty. If within 24 months after the end of the private offering Middlefield raises additional equity from an investor contacted by Boenning, Boenning will be entitled by the Placement Agency Agreement to a commission at the same rate applicable to the 2016 private sales. Boenning is entitled to indemnification from Middlefield for liabilities arising out of the private offering, as well as contribution by Middlefield to the damages, costs, and expenses that may be incurred by Boenning. Boenning has the right of first refusal to act as Middlefield’s placement agent if Middlefield engages in a rights offering to stockholders at any time before July 1, 2017, with a 5.0% commission rate on sales to persons who became Middlefield stockholders through the private offering and a reduced commission rate for sales to directors, executives, and other stockholders.

Middlefield also has an investment banking relationship of long standing with Donnelly Penman & Partners Inc. In early April 2016, after Middlefield management initially declined Boenning’s invitation to bid on the Liberty transaction, Donnelly Penman informed Middlefield management that a number of other potential

49

bidders also had declined to submit bids because of other acquisition transactions or for other reasons not having to do with Liberty. With a reduced number of potential bidders, Donnelly Penman suggested that management reconsider the decision not to submit a bid, outlining in very general terms a deal proposal management could consider making. Management discussed this with the Executive Committee of the board of directors of Middlefield at a meeting on Tuesday, April 12, 2016, a meeting at which the principal item of business was the private placement transaction that management desired to complete. The directors on the Executive Committee were Directors Turk, Skidmore, Caldwell, and Heslop. Director Darryl Mast also joined the meeting.

The Executive Committee and Director Mast convened again two days later, on April 14, 2016, to discuss the Liberty proposal, with representatives of Donnelly Penman present as well. At this meeting a deal proposal was outlined by Donnelly Penman and discussed at length, with consideration given to transaction-related costs such as the cost of Liberty’s data processing contract and the costs associated with Liberty’s executive severance arrangements, the future of Liberty’s student loan portfolio, the uncertain status of Liberty’s recently added loan production office in Wooster, Wayne County, Ohio, potential loss of Liberty’s significant deposit customers, the source of funds for the cash component of the potential transaction and the potential dilution resulting from the equity component, the effect of the acquisition on Middlefield’s regulatory capital, and potential cost savings that could result for the combined organization if redundancies are eliminated after acquisition. Aware of the Monday, April 18, 2016, deadline for submitting bid proposals, the committee authorized management to request from Donnelly Penman a post-acquisition financial projection revised to assume loss of Liberty’s two deposit customers, who according to the confidential information memorandum together accounted for deposits of more than $50 million, and sale of Liberty’s student loan portfolio at a slight loss.

On Friday, April 15, 2016 the Executive Committee – Directors Turk, Skidmore, Caldwell, and Heslop – reviewed Donnelly Penman’s revised projections of financial results. The committee concluded that the overall effect of the revised assumptions was not materially adverse, noting that the period to earn back the dilution of Middlefield’s tangible book value and the period in which the transaction becomes accretive to Middlefield’s earnings are within Middlefield’s internal guidelines, although the tangible book value dilution is slightly outside of the guidelines’ recommended range. Authorizing management to submit a nonbinding bid at the price of 125% of Liberty’s tangible book value, the committee instructed management that the bid must be subject to the condition that Liberty sell its student loan portfolio and declare a special cash dividend before acquisition closing to reduce excess capital.

With a 24-hour extension for submitting the indication of interest, the same Executive Committee members met again on Monday, April 18, 2016, to finalize Middlefield’s bid, with Donnelly Penman participating by telephone conference. Subject to obtaining legal review, the Executive Committee authorized management to submit to Boenning & Scattergood a bid in the form of a nonbinding letter of intent, with a total transaction value in the range of approximately 125% to 130% of tangible book value, or 137.5% to 145.0% of tangible book value adjusted for the proposed special cash dividend. Recognizing that Liberty stockholders would possess approximately 17% of Middlefield’s outstanding stock after the acquisition, Middlefield agreed to offer two board seats to Liberty, one at the level of the holding company and another at the level of The Middlefield Banking Company. Middlefield submitted its bid by the Tuesday, April 19, 2016 deadline.

On April 19, 2016 Boenning & Scattergood informed Middlefield that it was one of four bidders (three banks and one individual investor) being invited to perform due diligence and thereafter to submit a final bid. Middlefield submitted its due diligence request list to Boenning & Scattergood on April 22, 2016

CEO Thomas G. Caldwell updated the board at its May 9, 2016 regular meeting about the status of Middlefield’s indication of interest. CEO Thomas G. Caldwell, COO James R. Heslop, II, and CFO Donald L. Stacy met on Thursday, May 12, 2016, with Liberty’s board of directors, the day immediately after Middlefield’s 2016 annual meeting, outlining for the benefit of Liberty’s board the terms of Middlefield’s acquisition proposal. Middlefield representatives performed on-site due diligence of Liberty on May 9, 10, and 11, and during this period and thereafter Middlefield and its advisors made use of Boenning & Scattergood’s electronic

data room, where books and records of Liberty were available confidentially. On May 20, 2016 CEO Thomas G. Caldwell had a breakfast meeting at which he was introduced by Liberty’s CEO William A Valerian to Director Thomas W. Bevan Mr. Bevan is not only a director of Liberty but also controls an organization that is one of Liberty’s two largest depositors.

Middlefield’s Executive Committee met again on May 25, 2016, with Directors Turk, Skidmore, Caldwell, and Heslop and with Director Mast added to the Executive Committee’s membership. Representatives of Donnelly Penman attended the May 25, 2016 meeting by teleconference. The committee noted with approval that the Liberty acquisition would give Middlefield the opportunity to achieve its goal of entering the Cuyahoga County and Summit County markets, add SBA lending expertise to Middlefield’s lending products and services, generate income through sale of the government-guaranteed portion of SBA loans into the secondary market, and with Liberty’s student loan product constitute another potential addition to Middlefield’s loan products and services. Donnelly Penman discussed its updated merger analysis, slightly decreasing its estimate of the post-acquisition value of Liberty’s loan portfolio, reducing the estimated loss of deposits after the acquisition, which is referred to as deposit runoff, and slightly reducing the estimated severance benefits payable to Liberty executives as a result of the acquisition. Donnelly Penman’s updated analysis also took into account Middlefield’s ongoing private placement, which would strengthen Middlefield’s capital position, and presented updated projections of Middlefield’s financial condition on a stand-alone basis (stand-alone meaning without taking the merger into account).

For the final bid Donnelly Penman outlined a proposed price of 145% of Liberty’s adjusted tangible book value, for a total transaction value of approximately $39.6 million, including a $12.5 million special dividend payable by Liberty before closing, with 50% of the merger consideration consisting of cash and the other half Middlefield stock. The requirement that Liberty sell the student loan portfolio was no longer part of Middlefield’s proposal, because the portion of Liberty’s student loan portfolio maintained on Liberty’s books performs satisfactorily and the portion originated for sale has significant associated correspondent deposit balances maintained at Liberty by the parties to whom Liberty sells the loans. The May 25 meeting ended with the committee agreeing to recommend that the full board approve the proposed transaction terms at the board’s June 6 special meeting, one day before the June 7 final bid deadline. Donnelly Penman met again with the Executive Committee on June 1, 2016, updating the committee about the status of the letter of intent.

CEO Thomas G. Caldwell updated the board at its June 6 special meeting about the bid process. Donnelly Penman and Middlefield’s counsel joined the meeting by teleconference. By this time two of the four bidders invited to submit a final bid dropped out, leaving Middlefield and one unknown bidder remaining. Based on conversations with Thomas W. Bevan, a director of Liberty and one of its two largest depositors, the projected deposit runoff calculated by Donnelly Penman was reduced again. Mr. Caldwell noted favorably to the board that Liberty and Middlefield have a community banking focus in common, that Liberty does not have material asset quality concerns, that the due diligence process revealed nothing negative about Liberty, that Liberty’s offices are located in Middlefield’s targeted area of expansion, and that Liberty’s SBA lending would expand Middlefield’s products and potentially generate income from sale of the government-guaranteed portion of the SBA loans. For the proposed final bid, the period to earn back the estimated 16.5% dilution of Middlefield’s tangible book value and the period in which the transaction becomes accretive to Middlefield’s earnings remained within Middlefield’s internal guidelines, but the tangible book value dilution remained slightly outside of the guidelines’ recommended range. The board’s special meeting ended with unanimous approval for management to submit a final bid on the terms outlined at the meeting, at 145% of Liberty’s adjusted tangible book value, or approximately $40.54 per share (including the amount of the special dividend).

Middlefield submitted its final bid in the form of a nonbinding letter of intent on June 6, 2016. Liberty informed Middlefield that the final bids would be reviewed at Liberty’s board meeting on Friday, June 10. After the June 10 board meeting, at Liberty’s request Boenning & Scattergood informed Donnelly Penman that Liberty’s counterproposal was to obtain two holding company board seats at Middlefield, a $1.00 per share increase in the bid price, and a continued interest in future recoveries on previously charged off student loans.

At a special meeting of Middlefield’s board on Monday, June 13, with Donnelly Penman and Middlefield’s counsel joining by teleconference, the board approved a final offer, agreeing to add CEO William A. Valerian and Director Thomas W. Bevan to Middlefield’s board and agreeing to a price increase of approximately $0.55 per share, half in additional cash and half in additional Middlefield stock, but declined to offer Liberty a continued interest in future recoveries of previously charged off loans. The letter of intent also provided for continued indemnification and insurance coverage of Liberty’s officers and directors for six years after the transaction. Middlefield’s board also made clear that the company’s willingness to enter into a definitive acquisition agreement was conditioned on Liberty directors executing voting agreements, committing themselves to vote their Liberty shares in favor of the transaction with Middlefield.

Promptly after the June 13 special meeting Donnelly Penman informed Boenning & Scattergood of Middlefield’s final offer. Middlefield’s letter of intent was signed and returned by Liberty on June 14, 2016, and the parties then proceeded to negotiation of the definitive Reorganization Agreement. The letter of intent provided for the merger of Liberty into The Middlefield Banking Company in a transaction qualifying as a tax-free reorganization, at the price of 147% of Liberty’s adjusted tangible May 31, 2016 book value. Excluding approximately $1.147 million payable for cancellation of Liberty’s outstanding options and phantom stock, total transaction consideration under the final letter of intent was approximately $39.416 million, consisting of (1) $12.5 million in the form of a special cash dividend before acquisition closing, (2) $13.458 million in cash merger consideration, and (3) $13.458 million in stock merger consideration at a 0.882 fixed exchange ratio of Middlefield stock for 50% of Liberty stock, based on the $31.81 closing price for Middlefield stock on June 13, 2016.

Subsequently, Liberty’s outside tax counsel reviewed Middlefield’s revised indication of interest and, after consultation with and concurrence from Middlefield’s outside tax counsel, determined that the proposed payment by Liberty of a $12.5 million dividend to its stockholders immediately prior to completion of the Merger would adversely affect the tax-free reorganization treatment of the Merger and the ability of Liberty’s tax counsel to issue a favorable tax opinion. Following further discussions among the parties and their counsel, it was determined that the transaction should be restructured to reduce the Liberty special dividend from $12.5 million to approximately $3.0 million, increase the cash portion of the Merger consideration from 50% to 55% and decrease the common shares portion of the Merger consideration to 45%, while maintaining the same total transaction value. Over the next several weeks, the parties revised the Reorganization Agreement to reflect the latest structure of the transaction and negotiated its terms and conditions.

At a July 11, 2016 special meeting, with counsel present and Donnelly Penman present by teleconference, the board reviewed the status of the proposed transaction and the progress toward execution of the definitive acquisition agreement. Donnelly Penman presented a revised analysis of the transaction consideration, reducing from $12.5 million to $3.0 million the amount of the special cash dividend payable to Liberty stockholders before closing and increasing the portion of the cash merger consideration from 50% to 55%, with the stock portion therefore decreasing to 45%, while maintaining the total transaction value. According to Donnelly Penman’s analysis of the revised final terms, Liberty stockholders would have a slightly larger 18.7% stake in the combined Middlefield organization after acquisition, rather than the initial estimate of approximately 17%, Middlefield would earn back the tangible book value dilution within the time range sanctioned by Middlefield’s internal policy, and Middlefield’s regulatory capital ratios would be within policy limits as well. The slight increase in the number of shares to be issued to Liberty stockholders has the consequence of requiring a vote of Middlefield stockholders as well. The number of shares of Middlefield common stock issuable to Liberty stockholders slightly exceeds 20% of the number outstanding before the acquisition, requiring Middlefield approval under Nasdaq rules, and one-sixth of the number outstanding after the acquisition, requiring stockholder approval under OGCL section 1701.83(A).

On July 25, 2016, Liberty’s on-site due diligence investigation of Middlefield occurred, conducted by management of Liberty as well as a representative of Boenning. Liberty had been reviewing Middlefield’s SEC filings and additional information provided to Boenning, as well as information provided by Middlefield in connection with the May 12 presentation to the Liberty Board.

Middlefield’s board considered the proposed final Reorganization Agreement at a special meeting on July 27, 2016, with Donnelly Penman participating and Middlefield’s counsel present by teleconference. The Reorganization Agreement was signed on July 28, 2016. The board considered the slight change in the transaction structure, with the introduction of a first-step merger of MBC Interim Bank into Liberty occurring immediately before the merger of Liberty into The Middlefield Banking Company. The change in transaction structure is for the sole purpose of minimizing adverse potential tax consequences to The Middlefield Banking Company if the transaction does not qualify for tax-free reorganization treatment. Donnelly Penman presented its fairness opinion to the board and outlined the significant terms and financial impact of the transaction, including a special dividend of $3.13 per share for each of Liberty’s 959,283 outstanding shares, cash merger consideration of $20.88 per share and stock consideration valued at $17.08, for total consideration of approximately $39.1 million (including the special dividend), or $41.09 per share. Donnelly Penman informed the board that tangible book value dilution would be approximately 16.3%, projected to be earned back in a period of less than 3.5 years, with accretion to earnings exceeding 38% in the first year, an internal rate of return exceeding 20%, and a pro forma Tier 1 leverage ratio at The Middlefield Banking Company of 7.71% and a ratio of tangible common equity to tangible assets of 8.32%. Donnelly Penman informed the board that total consideration is approximately 1.31 times Liberty’s tangible book value and 19.12 times last-twelve-months earnings, with a core deposit premium of 5.16%. The July 27, 2016 special meeting concluded with Middlefield’s board approving the Reorganization Agreement unanimously.

Liberty’s Reasons for the Merger

The Liberty Board of Directors has regularly reviewed and discussed Liberty’s business strategy, performance and prospects in the context of developments in the banking industry, the regulatory environment and the competitive landscape. Among other things, the board of directors from time to time has discussed various strategic alternatives, including both acquiring other institutions and being acquired by another institution. Based on Liberty’s continued growth, the board of directors believed that it would need to engage in a strategic transaction at some point in time.

For a considerable time, the board of directors of Liberty has been concerned about the increasing expense and complexity of regulatory compliance for financial institutions, as well as the competition among large and small financial institutions for the same loan and deposit products. The directors have discussed in recent years how to best ensure the continued sound operation and profitability of Liberty in the face of these concerns.

Over the years, the board considered from time to time how to best provide for the continued safe and sound operation and strong performance of Liberty in the challenging regulatory and competitive environment. The board also discussed the lack of liquidity of Liberty’s stock as well as management succession issues. These discussions included a number of formal and informal meetings at which the directors discussed, among other possibilities, whether to proceed with exploring the possibility of acquiring or merging with another bank. Board members received the unsolicited views of some Liberty stockholders regarding a need for greater liquidity in the Liberty shares. As a result of these stockholder discussions and the board’s concerns regarding the increasingly challenging competitive and regulatory environment, the board decided to consider the possibility of exploring a merger and to learn more about the current merger and acquisition market.

From time to time over the years, the board invited Boenning to make a presentation about regional and national merger and acquisition activity. During 2015, Boenning reviewed such trends as well as the procedure and timeline for soliciting nonbinding indications of interest from potential merger partners. Boenning also presented a list of bank and thrift holding companies that, according to Boenning’s analysis, might have a logical interest in a possible merger with Liberty. In evaluating whether to proceed with the possibility of soliciting potential merger partners, the board also considered the stated desires of some Liberty stockholders for greater liquidity in Liberty shares and the board’s long-held concerns regarding competition and regulation. After careful consideration of all the foregoing, the directors decided to consider Boenning’s presentation and reconvene at a later time to determine whether to pursue the process of soliciting interest in a possible merger.

At a meeting of the board held on December 14, 2015, the Liberty directors resumed their discussions regarding whether to enter into the process of soliciting interest in a possible merger. After lengthy consideration of all the foregoing factors, and in light of the board’s numerous prior discussions regarding exploring the possibility of a merger, the board unanimously decided to proceed with the process, subject to the agreement and understanding that they could terminate the process at any time before the execution of a definitive agreement in the event that their expectations for stockholder value were not realized.

In January 2016, Boenning was hired by Liberty as its financial advisor to counsel Liberty with respect to a possible strategic transaction. Boenning assisted Liberty in preparing a confidential information memorandum and a limited data room containing certain financial and operational information of Liberty. Liberty and Boenning identified thirty-three (33) potential partners to contact and inquire as to whether such party would be interested in reviewing the memorandum and data room. Of those parties, twenty-two (22) executed confidentiality agreements and accessed the data room and four (4) submitted written indications of interest, three of which were from other banks and one of which was an individual investor. On April 19, 2016, the board of directors met to consider the four (4) indications of interest. The board of directors reviewed with Boenning the current state of the national and local banking markets, as well as the current environment for bank transactions. The board of directors also reviewed in detail each potential partner’s business, operations and financial performance. The board of directors discussed each of the indications of interest in detail and considered the merits of an all cash offer versus a part-stock, part-cash offer. The board of directors also reviewed and considered the financial and operating performance of each party and considered the effect of each offer on the submitting party’s financial condition. The board, with the advice of Boenning, determined that providing these four (4) bidders the opportunity to continue the due diligence process would maintain a competitive bidding process, while minimizing the potential disruption to Liberty’s operations. Each of the parties subsequently conducted a thorough due diligence process, including on-site meetings with Liberty management and extensive review of materials in the online data room.

At a special meeting of the board of directors on June 10, 2016, Boenning informed the board that two (2) of the potential acquirers had decided not to continue in the process, leaving two finalists. At that same meeting, the board reviewed the remaining two (2) indications of interest in detail and provided Boenning with a list of requested changes to each indication of interest. Boenning contacted each party to review and discuss the board’s requested changes and provided each party a last opportunity to increase its bid.

At a telephonic special meeting of the board of directors on June 14, 2016, Liberty’s board of directors reviewed the two (2) final bid offers and reviewed the process that had resulted in an attractive price for Liberty. The board considered the value of each offer and the liquidity each one provided to its stockholders, while also evaluating the merits of remaining independent and growing Liberty organically or through acquisitions. The board also considered the quality of Middlefield’s operating performance as well as a relative valuation of Middlefield’s stock that appeared to be attractive for those Liberty stockholders electing to receive stock. The board determined that the updated oral offer from Middlefield was in the best interest of the stockholders and authorized management to execute the latest indication of interest from Middlefield. Specifically, Middlefield’s revised indication of interest provided for a price increase of approximately $0.55 per share of Liberty common stock and inclusion of two (2) current directors of Liberty (Messrs. Bevan and Valerian) on the Middlefield board of directors immediately following the closing of the transaction. Middlefield’s revised indication of interest also contemplated that, immediately prior to the consummation of the Merger, Liberty would distribute a $12.5 million special dividend to its stockholders.

The parties executed the revised indication of interest on June 14, 2016 and began preparation of the Reorganization Agreement. Subsequently, Liberty’s outside tax counsel reviewed Middlefield’s revised

indication of interest and, after consultation with and concurrence from Middlefield’s outside tax counsel, determined that the proposed payment by Liberty of a $12.5 million dividend to its stockholders immediately prior to completion of the Merger would adversely affect the tax-free reorganization treatment of the Merger and the ability of Liberty’s tax counsel to issue a favorable tax opinion. Following further discussions among the parties and their counsel, it was determined that the transaction should be restructured to reduce the Liberty special dividend from $12.5 million to approximately $3.0 million, increase the cash portion of the Merger consideration from 50% to 55% and decrease the common shares portion of the Merger consideration to 45%, while maintaining the same total transaction value. Over the next several weeks, the parties revised the Reorganization Agreement to reflect the latest structure of the transaction and negotiated its terms and conditions.

At a meeting of the board of directors on July 27, 2016, the board of directors reviewed in detail the Reorganization Agreement and also received the opinion from Boenning that the Merger consideration was fair to Liberty’s stockholders from a financial point of view. The board of directors authorized the execution of the Merger Agreement, and each member of the board of directors who owns Liberty common stock entered into a written agreement to vote all of the Liberty shares that he or she beneficially owns in favor of the approval of the transactions contemplated by the Reorganization Agreement.

Management of Liberty signed the Reorganization Agreement on behalf of Liberty as of July 28, 2016 on the terms approved by the board of directors.

Recommendation of Liberty’s Board of Directors

The directors of Liberty believe that adoption and approval of the Reorganization Agreement and approval of the transactions contemplated by the Reorganization Agreement are in the best interest of Liberty and its stockholders. Consequently, the directors unanimously recommend that Liberty stockholders adopt and approve the Reorganization Agreement and approve the transactions contemplated by the Reorganization Agreement. The directors of Liberty have agreed to vote their shares of Liberty common stock in favor of the Merger Proposal.

Opinion of Liberty’s Financial Advisor

Boenning is acting as financial advisor to Liberty in connection with the proposed Merger. Boenning is a registered broker-dealer providing investment banking services with substantial expertise in transactions similar to the proposed Merger. As part of its investment banking activities, Boenning is regularly engaged in the valuation of businesses and securities in connection with mergers, acquisitions, underwritings, private placements and valuations for estate, corporate and other purposes.

On July 27, 2016, Boenning rendered its oral opinion, which was subsequently confirmed in writing, to the Liberty board of directors that, as of such date and subject to the assumptions made, matters considered and limitations of the review undertaken by Boenning, the Merger consideration to be received by the holders of Liberty’s common stock pursuant to the Reorganization Agreement was fair, from a financial point of view, to such holders.

The full text of Boenning’s written opinion dated July 27, 2016, which sets forth the assumptions made, matters considered and limitations of the review undertaken, is attached as Annex C to this proxy statement and is incorporated herein by reference. You are urged to, and should, read this opinion carefully and in its entirety in connection with this proxy statement.

##### Table of Contents

No limitations were imposed by Liberty on the scope of Boenning’s investigation or the procedures to be followed by Boenning in rendering its opinion. Boenning was not requested to, and did not, make any recommendation to the Liberty board of directors as to the form or amount of the consideration to be paid to the Liberty stockholders, which was determined through arm’s length negotiations between the parties. In arriving at its opinion, Boenning did not ascribe a specific range of values to Liberty. Its opinion is based on the financial and comparative analyses described below.

In connection with its opinion, Boenning, among other things:

| (i) | reviewed the historical financial performance, current financial position and general prospects of each of Middlefield and Liberty and reviewed certain internal financial analyses and forecasts prepared by the respective management teams of Middlefield and Liberty;

| (ii) | reviewed the Reorganization Agreement;

| (iii) | reviewed and analyzed the stock performance and trading history of Middlefield;

| (iv) | studied and analyzed the consolidated financial and operating data of Middlefield and Liberty;

| (v) | reviewed the pro forma financial impact of the proposed Merger on Middlefield, based on assumptions relating to transaction expenses, purchase accounting adjustments, cost savings and other synergies determined by the respective management teams of Middlefield and Liberty;

| (vi) | considered the financial terms of the proposed Merger as compared with the financial terms of comparable bank and bank holding company mergers and acquisitions;

| (vii) | met and/or communicated with certain members of each of Middlefield’s and Liberty’s senior management to discuss their respective operations, historical financial statements and future prospects; and

| (viii) | conducted such other financial analyses, studies and investigations as Boenning deemed appropriate.

Boenning’s opinion was given in reliance on information and representations made or given by Middlefield, Liberty, and their respective officers, directors, auditors, counsel and other agents, and on filings, releases and other information issued by each of Middlefield and Liberty including financial statements, financial projections, and stock price data as well as certain information from recognized independent sources. Boenning did not independently verify the information concerning Middlefield or Liberty nor any other data Boenning considered in its review and, for purposes of its opinion, Boenning assumed and relied upon the accuracy and completeness of all such information and data. Boenning assumed that all forecasts and projections provided to it had been reasonably prepared and reflected the best currently available estimates and good faith judgments of the respective management teams of Middlefield and Liberty as to their most likely future financial performance. Boenning expressed no opinion as to any financial projections or the assumptions on which they were based. Boenning did not conduct any valuation or appraisal of any assets or liabilities of Middlefield or Liberty, nor have any such valuations or appraisals been provided to Boenning. Additionally, Boenning assumed that the proposed Merger is, in all respects, lawful under applicable law.

With respect to anticipated transaction costs, purchase accounting adjustments, expected cost savings and other synergies and financial and other information relating to the general prospects of Middlefield and Liberty, Boenning assumed that such information had been reasonably prepared and reflected the best currently available estimates and good faith judgment of the respective management teams of Middlefield and Liberty as to their most likely future performance. Boenning further relied on the assurances of the respective management teams of Middlefield and Liberty that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Boenning was not asked to and did not undertake an independent verification of any of such information and Boenning did not assume any responsibility or liability for the accuracy or completeness thereof. Boenning assumed that the allowance for loan losses indicated on the balance sheet of each of Middlefield and Liberty was adequate to cover such losses; Boenning did not review individual

loans or credit files of Middlefield and Liberty. Boenning assumed that all of the representations and warranties contained in the reorganization Agreement and all related agreements were true and correct, that each party under the agreements will perform all of the covenants required to be performed by such party under the agreements, and that the conditions precedent in the agreements were not waived. Also, in rendering its opinion, Boenning assumed that in the course of obtaining the necessary regulatory approvals for the consummation of the proposed Merger no conditions will be imposed that will have a material adverse effect on the combined entity or contemplated benefits of the proposed Merger, including the cost savings and related expenses expected to result from the proposed Merger.

Boenning’s opinion is based upon information provided to it by the respective management teams of Middlefield and Liberty, as well as market, economic, financial and other conditions as they existed and could be evaluated only as of the date of its opinion and accordingly, it speaks to no other period. Boenning did not undertake to reaffirm or revise its opinion or otherwise comment on events occurring after the date of its opinion and did not have an obligation to update, revise or reaffirm its opinion. Boenning’s opinion does not address the relative merits of the proposed Merger or the other business strategies that Liberty’s board of directors has considered or may be considering, nor does it address the underlying business decision of Liberty’s board of directors to proceed with the proposed Merger. Boenning’s opinion is for the information of Liberty’s board of directors in connection with its evaluation of the proposed Merger and does not constitute a recommendation to the board of directors of Liberty in connection with the proposed Merger or a recommendation to any stockholder of Liberty as to how such stockholder should vote or act with respect to the proposed Merger.

In connection with rendering its opinion, Boenning performed a variety of financial analyses that are summarized below. This summary does not purport to be a complete description of such analyses. Boenning believes that its analyses and the summary set forth herein must be considered as a whole and that selecting portions of such analyses and the factors considered therein, without considering all factors and analyses, could create an incomplete view of the analyses and processes underlying its opinion. The preparation of a fairness opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Boenning considered the results of all of its analyses as a whole and did not attribute any particular weight to any analyses or factors considered by it. The range of valuations resulting from any particular analysis described below should not be taken to be Boenning’s view of the actual value of Liberty.

In its analyses, Boenning made numerous assumptions with respect to industry performance, business and economic conditions, and other matters, many of which are beyond the control of Liberty or Middlefield. Any estimates contained in Boenning’s analyses are not necessarily indicative of actual future values or results, which may be significantly more or less favorable than suggested by such estimates. Estimates of values of companies do not purport to be appraisals or necessarily reflect the actual prices at which companies or their securities actually may be sold. No company or transaction utilized in Boenning’s analyses was identical to Liberty or Middlefield or the proposed Merger. Accordingly, an analysis of the results described below is not mathematical; rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other facts that could affect the public trading value of the companies to which they are being compared. None of the analyses performed by Boenning was assigned a greater significance by Boenning than any other, nor does the order of analyses described represent relative importance or weight given to those analyses by Boenning. The analyses described below do not purport to be indicative of actual future results, or to reflect the prices at which Liberty’s common stock or Middlefield’s common stock may trade in the public markets, which may vary depending upon various factors, including changes in interest rates, dividend rates, market conditions, economic conditions and other factors that influence the price of securities.

In accordance with customary investment banking practice, Boenning employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses that Boenning used in providing its opinion on July 27, 2016. Some of the summaries of financial analyses are presented in tabular format. In order to understand the financial analyses used by Boenning more fully, you

##### Table of Contents

should read the tables together with the text of each summary. The tables alone do not constitute a complete description of Boenning’s financial analyses, including the methodologies and assumptions underlying the analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by Boenning. The summary data set forth below do not represent and should not be viewed by anyone as constituting conclusions reached by Boenning with respect to any of the analyses performed by it in connection with its opinion. Rather, Boenning made its determination as to the fairness to the holders of Liberty’s common stock of the Merger consideration, from a financial point of view, on the basis of its experience and professional judgment after considering the results of all of the analyses performed. Accordingly, the data included in the summary tables and the corresponding imputed ranges of value for Liberty should be considered as a whole and in the context of the full narrative description of all of the financial analyses set forth in the following pages, including the assumptions underlying these analyses. Considering the data included in the summary table without considering the full narrative description of all of the financial analyses, including the assumptions underlying these analyses, could create a misleading or incomplete view of the financial analyses performed by Boenning.

In connection with rendering its opinion and based upon the terms of the draft Agreement and Plan of Reorganization reviewed by it, Boenning assumed the effective aggregate indicated Merger consideration to be $41.57 million and the per share Merger consideration to be $42.14, based on Middlefield’s closing stock price on July 26, 2016, of $33.76.

Comparison of Selected Companies. Boenning reviewed and, as reflected in Table 1 below, compared the multiples and ratios of the offer price to Liberty’s book value, tangible book value, latest 12 months earnings per share, assets, tangible book premium to core deposits, and deposits, such multiples referred to herein as the pricing multiples, with the median pricing multiples for the current trading prices, after the application of a 29.7% assumed control premium, referred to as the adjusted trading price, of the common stock of a peer group of 22 selected public banks and thrifts with assets between $150 million and $400 million, tangible common equity / tangible assets between 11% and 15% and latest 12 months return on average tangible common equity between 5% and 8.5%, excluding merger targets. The 29.7% equity control premium is the median one day stock price premium for all bank and thrift merger and acquisition deals announced since January 1, 2000, based on data from SNL Financial.

Analysis of Bank Merger Transactions. Boenning analyzed certain information relating to recent transactions in the banking industry, consisting of (i) nine Midwest bank and thrift transactions announced since January 1, 2014 with target assets between $100 million and $600 million, tangible equity / tangible assets between 11% and 17%, latest 12 months return on average equity between 5% and 10%, and disclosed pricing, referred to below as Group A; and (ii) 17 nationwide bank and thrift deals announced since January 1, 2014 with target assets between $150 million and $400 million, tangible equity / tangible assets between 12% and 18%,

##### Table of Contents

latest 12 months return on average equity between 2% and 12%, and disclosed pricing, referred to below as Group B. As reflected in Table 2 below, Boenning then reviewed and compared the pricing multiples of the offer price and the median pricing multiples of the selected transaction values for Group A and Group B.

Table 2

|  |  |  |  | Median for Selected Transactions |
Pricing Multiple |  | The Merger |  |  | Group A |  |  | Group B |

Discounted Cash Flow Analysis. Discounted cash flow analysis approximates the value of a share of stock to an acquiror by calculating the present value of the target’s dividendable cash flow in perpetuity. This analysis assumed a short-term earnings growth rate of 5% and a long-term growth rate of 2%, as well as a short-term balance sheet growth rate of 3.5% and a long-term growth rate of 2%, based on guidance from Liberty’s management. The estimated cost savings of 30% in year one, 35% in year two and 40% thereafter, transaction costs of $3.1 million pre-tax and gross credit mark of approximately $5.1 million, or 2.75% of loans (equal to $1.8 million net of Liberty’s loan loss reserve) were based on guidance provided by Middlefield. A discount rate of 13% was determined using the Capital Asset Pricing Model and the Build-Up Method, both of which take into account certain factors such as the current risk free rate, the beta of bank stocks compared to the broader market and the Ibbotson risk premiums for small, illiquid stocks and for commercial bank stocks, as well as comparable company returns on tangible common equity. The average of the three methods was approximately 13%. Sensitivity analyses for discount rates and cost savings ranged from 11% to 15% and 33.5% to 46.5%, respectively. The present value of Liberty common stock calculated using discounted cash flow analysis ranged from $34.50 per share to $55.26 per share based on the cost savings estimates and discount rates used, compared to the offer price of $42.14 per share. This analysis does not purport to be indicative of actual future results and does not purport to reflect the prices at which shares of Liberty common stock may trade in the public markets. A discounted cash flow analysis was included because it is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, including earnings growth rates, dividend payout rates and discount rates.

Present Value Analysis. Applying present value analysis to Liberty’s theoretical future earnings, dividends and tangible book value, Boenning compared the offer price for one share of Liberty’s common stock to the present value of one share of Liberty’s common stock on a stand-alone basis. The analysis was based upon management’s projected earnings growth, a range of assumed price/earnings ratios, a range of assumed price/tangible book value ratios and a 13% discount rate, which was determined using the Capital Asset Pricing Model and the Build-Up Method, both of which take into account certain factors such as the current risk free rate, the beta of bank stocks compared to the broader market and the Ibbotson risk premiums for small, illiquid stocks and for commercial bank stocks, as well as comparable company returns on tangible common equity. The average of the three methods was approximately 13%. The valuation was completed with a sensitivity analysis on the discount rate ranging from 11% to 15%. Boenning derived the terminal price/earnings multiple of 15.8x and terminal price/tangible book value multiple of 123.7% from the three-year median trading multiples of the SNL Bank < $500 Million Index as of July 26, 2016. Sensitivity analyses for terminal price/earnings and price/tangible book ranged from 11.4x to 20.2x and 103.4% to 144.0%, respectively. The present value of Liberty’s common stock on a standalone basis is $22.86 to $45.10 per share based on price/earnings multiples, and $22.55 to $40.65 per share based on price/tangible book value multiples, compared to the offer price of $42.14 per share. This analysis does not purport to be indicative of actual future results and does not purport to reflect the

59

##### Table of Contents

prices at which shares of Liberty’s common stock may trade in the public markets. A present value analysis was included because it is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, including earnings growth rates, dividend payout rates and discount rates.

Pro Forma Merger Analysis. Boenning analyzed certain potential pro forma effects of the Merger, assuming the following: (i) the proposed Merger is completed December 31, 2016; (ii) each share of Liberty’s common stock will be eligible to receive consideration of approximately $42.14 consisting of a $3.13 special cash dividend, $20.88 in cash, and $17.09 in Middlefield stock; (iii) estimated pre-tax cost savings of approximately 40% of Liberty’s non-interest expense on an annual basis, recognized 75% in 2017 and 87.5% in 2018; (iv) estimated one-time transaction-related costs of approximately $3.5 million pre-tax are expensed prior to closing; (v) Liberty performance was calculated in accordance with Liberty management’s earnings forecasts; (vi) Middlefield’s performance was calculated in accordance with Middlefield management’s earnings forecasts; and (vii) certain other assumptions pertaining to costs and expenses associated with the transaction, intangible amortization, opportunity cost of cash and other items. The analyses indicated that, for the full years 2017 and 2018, the proposed Merger (excluding transaction expenses) would be accretive to the combined company’s projected earnings per share and accretive to Liberty’s per share equivalent earnings, tangible book value and dividends. Additionally, the combined company’s regulatory capital ratios would exceed regulatory guidelines for “well capitalized.” The actual results achieved by the combined company may vary from projected results and the variations may be material.

As described above, Boenning’s opinion was just one of the many factors taken into consideration by the Liberty board of directors in making its determination to approve the proposed Merger.

Boenning, as part of its investment banking business, regularly is engaged in the valuation of assets, securities and companies in connection with various types of asset and security transactions, including mergers, acquisitions, private placements, public offerings and valuations for various other purposes, and in the determination of adequate consideration in such transactions. In the ordinary course of Boenning’s business as a broker-dealer, it may, from time to time, purchase securities from, and sell securities to, Middlefield, Liberty, and/or their respective affiliates. In the ordinary course of business, Boenning may also actively trade the securities of Middlefield and Liberty for its own account and/or for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

Boenning is acting as Liberty’s financial advisor in connection with the proposed Merger and will receive a customary fee for its services, a significant portion of which is contingent upon consummation of the Proposed Merger. Boenning also received a fee for rendering the fairness opinion. Boenning’s fee for rendering the fairness opinion was not contingent upon any conclusion that Boenning reached or upon completion of the proposed Merger. The Company has also agreed to indemnify Boenning against certain liabilities that may arise out of Boenning’s engagement.

Prior Engagements by Middlefield and Liberty. Boenning was engaged in February 2016 by Middlefield to serve as placement agent for a private placement of common stock. The offering ultimately closed on June 30, 2016, and Boenning was paid a commission for its role. Boenning advised, and received compensation from, Liberty in 2014 relating to the exploration of strategic alternatives, although no transaction was consummated at that time.

Except for the arrangements between Boenning and Liberty and Middlefield described in the preceding paragraphs, Boenning has not had any material relationship with either Middlefield or Liberty during the past two years in which compensation was received or was intended to be received. Boenning may provide services to Middlefield in the future (and/or to Liberty if the proposed Merger is not consummated), although as of the date of Boenning’s opinion, there was no agreement to do so nor any mutual understanding that such services are contemplated.

##### Table of Contents

Boenning’s opinion was approved by Boenning’s fairness opinion committee. Boenning did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the proposed Merger by any of the officers, directors, or employees of any party to the reorganization Agreement, or any class of such persons, relative to the compensation to be received by the holders of Liberty’s common stock in the proposed Merger.

Nonpublic Financial Projections Provided to Financial Advisors

For a number of reasons, including the unpredictability of underlying assumptions and estimates, Liberty does not routinely publicly disclose forecasts or internal projections of future performance, earnings, or other results. However, Boenning & Scattergood, Inc. used financial projections provided by or reviewed with senior management of Liberty for the purpose of preparing the financial analyses supporting Boenning & Scattergood’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Liberty’s Financial Advisor.” In addition, Donnelly Penman & Partners Inc. used internal financial projections provided by and/or reviewed with senior management of Liberty for the purpose of preparing the financial analyses supporting Donnelly Penman’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Middlefield’s Financial Advisor.” A summary of these projections is therefore included in this joint proxy statement/prospectus because the projections were used by Boenning and by Donnelly Penman.

When the financial projections were prepared, they represented the best estimates and judgments of Liberty management about future financial performance. The financial projections summarized below were prepared in good faith, but financial projections are subjective in many respects and are susceptible to interpretation and periodic revision based on actual experience and recent developments. Accordingly, financial projections do not reliably predict future operating results. The financial projections were not prepared with the expectation of public disclosure or with the goal of complying with American Institute of Certified Public Accountants guidelines for prospective financial information or SEC guidelines regarding forward-looking statements. Although presented with numeric specificity, the financial projections reflect numerous estimates and assumptions that might not be realized and are subject to significant uncertainties and contingencies, many of which are beyond Liberty’s control. For these reasons and because of the uncertainties inherent in financial projections, Liberty stockholders and Middlefield stockholders should not unduly rely on these financial projections as predictions of future operating results.

The financial projections of Liberty included in this joint proxy statement/prospectus were prepared by and are the responsibility of Liberty management. Neither Liberty’s independent registered public accounting firm nor any other independent accounting firm examined, compiled, or performed any procedures on these financial projections, and therefore express no opinion or any other form of assurance regarding the financial projections. Inclusion of the financial projections in this joint proxy statement/prospectus is not an admission or representation by Liberty or Middlefield that Liberty or Middlefield consider the financial projections to be material information.

All of the financial projections are forward-looking statements. The estimates and assumptions underlying the financial projections summarized below involve judgments regarding future economic, competitive, regulatory, and financial market conditions and future business decisions. The estimates and assumptions may not be realized and are inherently subject to significant business, economic, competitive, and regulatory uncertainties, all of which are difficult to predict and many of which are beyond Liberty’s control. In addition, these financial projections represent Liberty’s evaluation at the time the projections were prepared of its future financial performance on a stand-alone basis, and without reference to the proposed Merger or transaction-related costs or benefits. Accordingly, Liberty gives no assurance that the projected results will be realized or that actual results will not differ materially from those presented in the financial projections. Inclusion of these financial projections should not be interpreted as a statement that Liberty or Middlefield considers this information a reliable prediction of future results, or that the projections would be the same if prepared by Liberty as of the date of this document, and this information should not be unduly relied on for that purpose.

Middlefield’s Reasons for the Merger

Middlefield’s board of directors believes the Merger is in the best interests of Middlefield and its stockholders and therefore unanimously approved the transactions contemplated by the Reorganization Agreement and the Merger. The board reached this decision after consulting with management and with Middlefield’s financial and legal advisors. The board’s reasoning was based on many factors, including but not limited to the following:

• |  | the Merger will expand Middlefield’s northeastern Ohio business into Cuyahoga County and Summit County, two counties to the immediate west and south of Middlefield’s market but contiguous to Middlefield’s market

• |  | Liberty has a diversified loan portfolio, but its primary focus on commercial lending opportunities targeted to professionals and small business owners is compatible with Middlefield’s goals and could allow for significant lending growth in these markets

• |  | the Merger will make Middlefield a leading community banking organization in desirable markets within northeastern Ohio, adding scale, profitability, and growth potential

• |  | Middlefield anticipates that eliminating back office redundancies will lead to savings opportunities

• |  | although there are regional and national financial institutions in northeastern Ohio with significantly greater assets, at approximately $1.0 billion in total assets after the Merger Middlefield will not lose its identity as a community banking organization but it will have improved economies of scale to compete more effectively in an increasingly competitive and increasingly concentrated banking market, along with enhanced growth opportunities through three productive new offices in the Cleveland and Akron markets

• |  | the resulting institution will have a stronger regional presence and greater brand recognition

• |  | Liberty customers will have access to a broader range of banking products and services from a bank with greater lending authority

• |  | Liberty’s SBA lending will be a positive addition to Middlefield’s lending products, potentially also generating income from sale of the government-guaranteed portion of the SBA loan portfolio

• |  | The Middlefield Banking Company and Liberty are compatible organizations because of similar strategies and a shared customer focus and community orientation

• |  | the pro forma financial aspects of the Merger are favorable, with an estimated earnings per share accretion in 2017 of over 38% and an estimated internal rate of return exceeding 20%, with a manageable three- to four-year period to earn back the approximately 16% anticipated tangible book value dilution

• |  | when Liberty board members William A. Valerian and Thomas W. Bevan become Middlefield board members at Merger closing their insights about Middlefield’s expanded market in Cuyahoga and Summit Counties will enable Middlefield to take greater advantage of competitive opportunities in that expanded market

• |  | The continued employment of Liberty personnel will help with the transition of customers, employees, and the Liberty community, reducing the Merger’s potential execution risk

• |  | The Middlefield Banking Company will continue to be well capitalized after the Merger

Middlefield’s board of directors considered many factors in its evaluation. The board did not quantify or assign relative weights to any individual factors in its decision.

Recommendation of Middlefield’s Board of Directors

Middlefield’s board of directors unanimously approved the transactions contemplated by the Reorganization Agreement and the issuance of common stock in the Merger. The board believes the Merger and the common stock issuance are in the best interests of Middlefield and its stockholders. Accordingly, the directors unanimously recommend that Middlefield stockholders vote “FOR” adoption and approval of the Reorganization Agreement and “FOR” issuance of common stock in the Merger.

Opinion of Middlefield’s Financial Advisor

On April 19, 2016 Middlefield’s board of directors retained Donnelly Penman to provide merger advisory services. As part of the engagement, Donnelly Penman was asked to assess the fairness to Middlefield stockholders, from a financial point of view, of the approximately $40.0 million consideration being paid.

Donnelly Penman is a regional investment banking firm headquartered in Grosse Point, Michigan. Donnelly Penman is continually engaged in the valuation of businesses and securities in mergers and acquisitions, in secondary distributions of securities, and in private placements, as well as valuations for going-private transactions, corporate, and other purposes.

Donnelly Penman representatives attended the July 27, 2016 meeting at which Middlefield’s board of directors evaluated and ultimately approved the Reorganization Agreement and proposed Merger. At this meeting Donnelly Penman reviewed the financial aspects of the proposed transaction and rendered an opinion that as of such date the approximately $40.0 million consideration being paid, including the cash and stock consideration payable to Liberty stockholders in exchange for their Liberty common stock, the approximately $3.0 million special dividend to be declared by Liberty before closing, and the approximately $1.1 million payable in cancellation of Liberty’s outstanding options and phantom stock, was fair from a financial point of view to Middlefield stockholders.

The full text of Donnelly Penman’s written opinion is attached as Annex D to this joint proxy statement/prospectus. The following summary of the opinion is qualified in its entirety by reference to the full text of the opinion in Annex D. You should read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Donnelly Penman. Donnelly Penman’s opinion is necessarily based upon economic and market conditions and other circumstances as they existed and were evaluated on the date of the opinion.

Donnelly Penman’s opinion speaks only as of the date of the opinion. The opinion is directed to Middlefield’s Board of Directors and addresses only the fairness to Middlefield stockholders, from a financial point of view, of the consideration being paid. It does not address the underlying business decision to proceed with the Merger and does not constitute a recommendation to any stockholder about how the stockholder should vote regarding the Merger.

Donnelly Penman discussed current business operations, financial conditions and prospects of Middlefield and Liberty the management teams of Middlefield and Liberty, in addition to discussions with independent directors of Middlefield. The resources Donnelly Penman reviewed in the process of forming its fairness opinion also include but are not limited to the following:

| • |  | the July 28, 2016 Reorganization Agreement and exhibits

| • |  | public information of Middlefield, including audited financial statements and Form 10-Ks for the years ended December 31, 2015, 2014 and 2013, interim financial results for the six months ended June 30, 2016 and 2015 as disclosed in Form 10-Q, and the quarterly call reports of The Middlefield Banking Company for the periods March 31, 2016 and December 31, September 30, June 30, and March 31, 2015

| • |  | senior management’s projected earnings estimates for fiscal years 2016 through 2018, which Donnelly Penman extrapolated into fiscal year 2020

| • |  | nonpublic information about Liberty made available in the due diligence process, including Liberty’s audited financial statements for the years ended December 31, 2015, 2014, and 2013, as well as publicly available information, including Liberty’s quarterly call reports for quarters ended on June 30 and March 31, 2016 and December 31, September 30, June 30, and March 31, 2015

| • |  | Liberty’s problem loan reports as of March 31 and June 30, 2016

| • |  | Liberty senior management’s projected earnings estimates for fiscal years 2016 through 2018, which Donnelly Penman extrapolated into fiscal year 2020

| • |  | valuation analyses of Middlefield that Donnelly Penman performed, including analysis of comparable transactions, a dividend discount model analysis on a standalone basis for Middlefield and on a pro forma basis including Liberty, and analysis of comparable public companies to Middlefield on a standalone and pro forma basis

| • |  | a summary merger model of the pro forma impact of the transaction to Middlefield

| • |  | a contribution analysis of Middlefield and Liberty to the combined entity as of June 30, 2016, and

| • |  | other information, financial studies, analyses, investigations, and factors that Donnelly Penman deemed relevant

Donnelly Penman also discussed with Middlefield management past and current business operations, regulatory relations, financial condition, future prospects, and other matters. Donnelly Penman also discussed with Liberty management that bank’s business operations, regulatory relations, earnings results, and future prospects.

Donnelly Penman relied upon the accuracy and completeness of all financial and other information provided to it or publicly available, and did not assume responsibility for the accuracy, completeness, or reasonableness of or responsibility for verification of the information. Donnelly Penman did not make any independent evaluations, valuations, or appraisals of the assets or liabilities of Middlefield or Liberty, did not review individual credit files, and assumed that the aggregate allowances for credit losses relating to the loans of Middlefield and Liberty are and will continue to be adequate to cover losses. Donnelly Penman relied upon Middlefield management regarding the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefor) prepared by and provided by Middlefield management, and similarly relied on Liberty management regarding the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefor) prepared by and provided by Liberty management. Donnelly Penman assumed that the forecasts and projections of Middlefield management reflect management’s best

64

##### Table of Contents

currently available estimates and judgments and that the forecasts and projections will be realized in the amounts and in the time periods estimated and that they provide a reasonable basis for Donnelly Penman’s opinion. Likewise, Donnelly Penman assumed that the forecasts and projections of Liberty management reflect Liberty management’s best currently available estimates and judgments and that the forecasts and projections will be realized in the amounts and in the time periods estimated and that they provide a reasonable basis for Donnelly Penman’s opinion. The Middlefield and Liberty forecasts and projections were not prepared with the expectation of public disclosure. The projected financial information is based on numerous variables and assumptions that are inherently uncertain, including without limitation factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from projected results. Donnelly Penman relied on the projected information without independent verification or analysis. Donnelly Penman relied upon the assurance of Middlefield management and Liberty management that they were unaware of any facts that would make the information provided or available to Donnelly Penman incomplete or misleading.

The following is a summary of the material analyses presented by Donnelly Penman to the Middlefield’s board of directors on July 27, 2016. The Donnelly Penman opinion was not the only factor taken into consideration by Middlefield’s board of directors in the board’s decision to approve the Reorganization Agreement and the Merger. Consequently, the analyses described below were not determinative in the board’s decision. The summary is not a complete description of the analyses underlying the Donnelly Penman opinion or the presentation made by Donnelly Penman to Middlefield’s board of directors, but summarizes the material analyses performed and presented. The preparation of a fairness opinion is a complex analytic process. Donnelly Penman did not attribute any particular weight to any analysis or factor it considered, but rather made qualitative judgments about the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. Accordingly, Donnelly Penman believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion.

The summary of Donnelly Penman’s analyses to follow includes a summary of its analysis of comparable transactions, analysis of a dividend discount model on a stand-alone basis for Middlefield (stand-alone meaning without taking the Merger into account) and on a pro forma, post-merger basis, analysis of tangible book value dilution and earnings accretion attributable to the Merger, analysis of comparable public companies to Middlefield on a stand-alone basis and pro forma basis, and finally a contribution analysis that considers the anticipated 18.7% pro forma outstanding shares of Middlefield common stock held by Liberty stockholders relative to the percentage contribution of Liberty assets, loans, deposits, and tangible common equity to the pro forma combined entity. Donnelly Penman made numerous assumptions regarding industry performance, business and economic conditions, and other matters, many of which are beyond the control of Middlefield and Liberty. Credit, financial, and stock markets can experience unusual volatility. No company or merger included in Donnelly Penman’s analysis is identical to Middlefield or Liberty and the comparable transactions considered by Donnelly Penman are not identical to the proposed Merger. Accordingly, Donnelly Penman’s analyses are not based solely on arithmetic calculations but instead involve complex considerations and judgments concerning differences in financial and operating characteristics of the relevant companies, the timing of the relevant mergers and prospective buyer interests, as well as other factors that could affect the public trading markets of companies to which Middlefield is being compared. None of the analyses performed by Donnelly Penman was assigned a greater significance than any other.

Comparable Transaction Analysis. Donnelly Penman reviewed publicly available information related to comparable acquisitions of banks and bank holding companies as well as thrifts and thrift holding companies. The selection criteria were (1) transaction announcement after June 30, 2014, (2) total assets of acquired company between $100 and $300 million, (3) last twelve month (LTM) return on average assets (ROAA) of acquired company between 0.75% and 1.00%, and (4) nonperforming assets as a percent of total assets of acquired company less than 3.0%. Based on these criteria, Donnelly Penman identified 22 comparable acquisition transactions on a national level –

Donnelly Penman considered the transaction price per share as a percent of the acquired company’s June 30, 2016 book value, as a percent of the acquired company’s tangible book value as of that date, as a multiple of the acquired company’s LTM earnings per share in the twelve-month period ended June 30, 2016, and as a percent of the acquired company’s June 30, 2016 core deposits, which generally consist of total deposits other than time deposits exceeding $100,000. For comparison purposes, Donnelly Penman calculated the total transaction price to be $40.6 million, or $42.28 per share, which is derived from an estimated $16,387,359 stock consideration to be issued in the Merger in exchange for 45% of Liberty’s 959,283 outstanding shares and an estimated $23,027,910 cash consideration. The cash component includes not only cash Merger consideration payable in exchange for Liberty common stock but also the $3.0 million special dividend and the approximately $1.1 million payable for cancellation of outstanding shares and phantom stock. As a percent of book value, tangible book value, LTM earnings per share, and core deposits, the $42.28 per share price is –

None of the companies or 22 transactions used as a comparison in these analyses is identical to Liberty, Middlefield, or the Merger. Analysis of these results is not solely mathematical, but instead involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies.

Dividend Discount Model Analysis. Donnelly Penman performed a discounted cash flow analysis of Middlefield on a stand-alone basis and on a pro forma, post-merger basis, estimating the value of a share of Middlefield common stock to be $34.56 on a stand-alone basis and $45.14 pro forma. These estimated values are the sum of two estimated values discounted back to the hypothetical December 31, 2016 merger date: (x) cash dividends for the five year period 2016 through 2020 and (y) residual or terminal value at the end of the five-year period. To determine present value, Donnelly Penman used a 13.00% discount rate.

Donnelly Penman’s estimate assumes Middlefield’s dividend remains constant at $1.08 annually both on a stand-alone basis and pro forma, post-merger. The per share values also assume Middlefield’s outstanding shares increase by 20,000 annually through Middlefield’s dividend reinvestment plan, with pro forma outstanding shares including the estimated 515,164 shares issuable to Liberty stockholders in the Merger. At a 13.00% discount rate, the present value of the five-year projected cash dividend income is $3.56 on a stand-alone and pro forma basis. For the estimated total $34.56 value of Middlefield on a stand-alone basis and $45.14 estimated pro forma value, the residual or terminal value at the end of the five-year period is derived by taking the average of a multiple of 1.40 times projected book value at the end of 2020 and 15.0 times projected 2020 net income, discounting that average value back to the December 31, 2016 hypothetical merger date at 13.0%. To derive the estimated stand-alone value, Donnelly Penman used Middlefield management’s forecasted figures for 2016 through 2018, extrapolating from that at 8.00% annual growth for the years 2019 and 2020. Likewise, to derive the estimated pro forma, post-merger value Donnelly Penman used Middlefield management’s and Liberty management’s forecasts for 2016 through 2018, extrapolating at 8.00% annual growth for the years 2019 and 2020. Net income assumes Middlefield’s effective tax rate is 22%. Because the projected allowance for loan losses at the end of 2018 is projected to exceed 1.25%, the pro forma estimate assumes no additional provision expense attributable to Liberty in the years 2017 and 2018, but earnings are based on a slower growth rate

67

##### Table of Contents

thereafter to anticipate provision expense in 2019 and 2020. For purposes of the pro forma estimate, Middlefield management estimates a 30% reduction of Liberty’s noninterest expense in 2017 and 35% thereafter.

Discounted cash flow present value analysis is a widely used valuation methodology, but it relies on numerous assumptions and estimates, including but not limited to asset and earnings growth rates, discount rates, and multiples of earnings or book value or both to derive residual or terminal values. The numeric per share result of the analysis is not the stock’s actual value or expected value. It is merely an estimate within a broad range of potential value estimates.

Tangible Book Value Dilution and Earnings Accretion. Donnelly Penman estimates that Middlefield’s tangible book value per share at December 31, 2016 would be $33.52 without taking the Merger into account, with 16.3% dilution, or $5.46 dilution per share, on a pro forma, post-merger basis at December 31, 2016. The Middlefield Banking Company’s pro forma Tier 1 leverage ratio would be 7.71%, with pro forma Total Risk-Based Capital of 10.89% and pro forma Tangible Common Equity as a percent of tangible assets at 8.32%. Donnelly Penman estimates that the dilution of tangible book value could be eliminated, or earned back, in a period ranging from three to four years, which is consistent with the 3.9 year median period to earn back tangible book value dilution in a group of nine recent acquisitions examined by Donnelly Penman. Those nine transactions were announced between July 2, 2013 and June 2, 2016, with the first three transactions not yet completed on the date of Donnelly Penman’s analysis in July 2016. The nine transactions involve acquired companies in Ohio, Indiana, Pennsylvania, and Michigan, with total deal values ranging from $30 million to $50 million –

Comparable Public Company Analysis. Donnelly Penman also analyzed a group of 20 publicly traded companies Donnelly Penman considers comparable to Middlefield on a stand-alone basis because of location, asset size, and return on average assets (ROAA). The companies are all located in the Midwest or the greater Midwest region, have total assets between $500 million and $1.0 billion, and have an ROAA between 0.75% and 1.25%. Taking their stock price as of July 22, 2016 and using publicly available data, Donnelly Penman determined that the companies’ price to book value, price to tangible book value, and price to LTM EPS (as of June 30, 2016) are –

|  | 7/22/2016 price to 6/30/2016 book value |  |  | 7/22/2016 price to 6/30/2016 tangible book value |  |  | 7/22/2016 price to LTM EPS as of 6/30/2016 |

Contribution Analysis. Assuming there are 515,164 shares of Middlefield common stock issued in the Merger to Liberty stockholders, Liberty stockholders will possess 18.7% of total pro forma shares outstanding but will contribute an average of 23.9% to the combined entity in terms of the entity’s total assets, total loans, total deposits, and tangible common equity as of June 30, 2016, and 2015 net income and last twelve months (as of June 30, 2016) net income –

Relationships. Donnelly Penman & Partners acted exclusively for the Middlefield board of directors in rendering the opinion included as Annex D to this joint proxy statement/prospectus. Donnelly Penman will receive a fee from Middlefield for its services. Donnelly Penman has also acted as Middlefield’s advisor for the Merger transaction, and a portion of Donnelly Penman’s fee is contingent on the Merger’s successful completion. Middlefield agreed to pay Donnelly Penman a $40,000 fee for the fairness opinion, agreeing to pay an additional $5,000 for each fairness opinion update. Additionally, Middlefield paid Donnelly Penman an initial advisory fee of $12,500 at execution of the April 19, 2016 engagement letter agreement and an additional advisory fee of $12,500 after Liberty identified Middlefield as one of the bidders invited to submit final bids. The advisory fees will be credited against the success fee payable to Donnelly Penman at Merger closing. The total success fee is $250,000, including a nonrefundable $75,000 portion that Middlefield paid when the Reorganization Agreement was signed. Donnelly Penman will receive the remaining portion of the success fee when the Merger is completed ($150,000, after crediting of the advisory fees). Middlefield agreed to reimburse Donnelly Penman for up to $7,500 of reasonable and customary out-of-pocket expenses and disbursements, also agreeing to indemnify Donnelly Penman against liabilities incurred for its services. The initial term of the engagement agreement ends December 31, 2016.

Donnelly Penman has provided advisory services to Middlefield in the past, including a March 2015 engagement concerning a potential acquisition, which did not lead to an acquisition transaction but for which Middlefield paid Donnelly Penman a retainer fee, and an October 2015 engagement concerning another potential acquisition, which also did not lead to an acquisition transaction but for which Middlefield paid Donnelly Penman a retainer. Donnelly Penman has never been engaged by Liberty for any purpose.

Nonpublic Financial Projections Provided to Middlefield’s Financial Advisor

For a number of reasons, including the unpredictability of underlying assumptions and estimates, Middlefield does not routinely publicly disclose forecasts or internal projections of future performance, earnings, or other results. However, Donnelly Penman & Partners Inc. used financial projections provided by or reviewed with senior management of Middlefield for the purpose of preparing the financial analyses supporting Donnelly Penman’s fairness opinion, as described in this joint proxy statement/prospectus under the heading “– Opinion of Middlefield’s Financial Advisor.” A summary of these projections is included in this joint proxy statement/prospectus because the projections were used by Donnelly Penman.

70

##### Table of Contents

When the financial projections were prepared, they represented the best estimates and judgments of Middlefield management about future financial performance. The financial projections summarized below were prepared in good faith, but financial projections are subjective in many respects and are susceptible to interpretation and periodic revision based on actual experience and recent developments. Accordingly, financial projections do not reliably predict future operating results. The financial projections were not prepared with the expectation of public disclosure or with the goal of complying with American Institute of Certified Public Accountants guidelines for prospective financial information or SEC guidelines regarding forward-looking statements. Although presented with numeric specificity, the financial projections reflect numerous estimates and assumptions that might not be realized and are subject to significant uncertainties and contingencies, many of which are beyond the control of Middlefield. For these reasons and because of the uncertainties inherent in financial projections, Liberty stockholders and Middlefield stockholders should not unduly rely on these financial projections as predictions of future operating results.

The financial projections of Middlefield included in this joint proxy statement/prospectus were prepared by and are the responsibility of Middlefield management. Neither Middlefield’s independent registered public accounting firm nor any other independent accounting firm examined, compiled, or performed any procedures on these financial projections, and therefore express no opinion or any other form of assurance regarding the financial projections. Inclusion of the financial projections in this joint proxy statement/prospectus is not an admission or representation by Liberty or Middlefield that Liberty or Middlefield consider the financial projections to be material information.

All of the financial projections are forward-looking statements. The estimates and assumptions underlying the financial projections summarized below involve judgments regarding future economic, competitive, regulatory, and financial market conditions and future business decisions. The estimates and assumptions might not be realized and are inherently subject to significant business, economic, competitive, and regulatory uncertainties, all of which are difficult to predict and many of which are beyond the control of Middlefield. In addition, these financial projections represent Middlefield’s evaluation at the time the projections were prepared of its future financial performance on a stand-alone basis, and without reference to the proposed merger or transaction-related costs or benefits. Accordingly, Middlefield gives no assurance that the projected results will be realized or that actual results will not differ materially from those presented in the financial projections. Inclusion of these financial projections should not be interpreted as a statement that Liberty or Middlefield considers this information a reliable prediction of future results, or that the projections would be the same if prepared by Middlefield as of the date of this document, and this information should not be unduly relied on for that purpose.

Middlefield provided to Donnelly Penman & Partners Inc. the following estimate of per share earnings for the period 2017 through 2022, both for Middlefield on a stand-alone basis and on a pro forma, post-merger basis:

|  | year ended December 31, |
|  | 2017 |  |  | 2018 |  |  | 2019 |  |  | 2020 |  |  | 2021 |  |  | 2022 |
EPS – stand-alone |  |  | 3.16 |  |  |  | 3.57 |  |  |  | 3.82 |  |  |  | 4.09 |  |  |  | 4.38 |  |  |  | 4.68 |
EPS – pro forma |  |  | 4.38 |  |  |  | 5.08 |  |  |  | 5.55 |  |  |  | 6.04 |  |  |  | 6.55 |  |  |  | 7.08 |

Regulatory Approvals Required

The Merger cannot be completed unless Middlefield and Liberty obtain regulatory approval. The Merger consists of two separate mergers: first a merger of Middlefield’s newly formed interim bank subsidiary into Liberty, followed immediately by the merger of Liberty into The Middlefield Banking Company. Accordingly, the Merger must be approved by the Office of the Comptroller of the Currency (OCC), Liberty’s principal federal regulator, and by the FDIC, The Middlefield Banking Company’s principal federal regulator. The Ohio Division of Financial Institutions (ODFI) also has jurisdiction over the Merger, which is a third required regulatory approval of the Merger itself. Declaration by Liberty of the special dividend before closing is an integral part of

71

##### Table of Contents

the transactions to be carried out under the Reorganization Agreement, but that special dividend cannot be paid unless Liberty first obtains OCC approval. Similarly, The Middlefield Banking Company and Middlefield must obtain ODFI approval of the approximately $9.0 million dividend to be paid by The Middlefield Banking Company to Middlefield, which is one of Middlefield’s sources of funds for the cash portion of the Merger consideration. The other source is borrowing of approximately $11.7 million. Finally, Middlefield also must obtain approval from the ODFI for formation of the interim bank subsidiary and approval from the FDIC of deposit insurance for the interim bank subsidiary. All of these regulatory approvals are Merger closing conditions. All necessary applications have been submitted. No approvals have been obtained. Although Liberty and Middlefield believe approvals will be obtained, neither Liberty nor Middlefield can assure you when or whether the approvals will be obtained, or if obtained what approval conditions might be imposed. Middlefield is also seeking from the Board of Governors of the Federal Reserve System waiver of the obligation to file an application under the Bank Holding Company Act of 1956.

Approval of a regulatory application merely implies satisfaction of regulatory criteria for approval, which does not include review of the adequacy or fairness of the Merger consideration to Liberty stockholders or Middlefield stockholders. Regulatory approvals do not constitute or imply any endorsement or recommendation of the Merger or the terms of the Reorganization Agreement.

Interests of Liberty’s Directors and Certain Executive Officers in the Merger

Officers and directors of Liberty have employment and other compensation agreements or economic interests that give them interests in the Merger that are somewhat different from or in addition to their interests as Liberty stockholders. These interests and agreements include –

| • |  | two members of the Liberty board of directors will be appointed to Middlefield’s board of directors. These directors are President and CEO William A. Valerian and Thomas W. Bevan,

| • |  | all outstanding stock options awarded by Liberty will be cancelled in exchange for cash equal to (x) the positive difference between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise. There are also outstanding 2,000 phantom share awards made in 2013, including an award of 1,000 shares made on January 29, 2013 to President and CEO William A. Valerian’s son, who also is an officer of Liberty. The phantom share awards consist of the right to a cash payment equal to the positive difference between Liberty’s stock value on December 31, 2016 and the stock value on the award date, multiplied by the number of phantom shares awarded, with value being determined by Liberty’s board of directors. The total cash payment for cancellation of the options and phantom awards is estimated be $1,147,516, of which $1,025,704 is payable to CEO, CFO, and Chief Credit Officer, and $15,200 is payable to the CEO’s son,

| • |  | Liberty’s President and CEO William A. Valerian and Chief Operating Officer and CFO Richard C. Ebner have employment agreements with Liberty. The employment agreements provide that they are entitled to a payment equal to 2.5 times salary when a change in control occurs, payable in equal installments over 30 months, plus a payments for the cost of life insurance, long-term disability, and medical benefits over those 30 months. The Merger will constitute a change in control under those employment agreements. Mr. Valerian’s total payments are estimated to be $904,611 and Mr. Ebner’s are estimated to be $697,317,

| • |  | Certain Liberty officers will receive retention bonuses to remain with Liberty through consummation of the Merger,

| • |  | The Reorganization Agreement provides that Middlefield will consult with Liberty about forming a Northeast Ohio Advisory Board, which would include some of Liberty’s current directors, and

| • |  | the Reorganization Agreement preserves for six years the rights of Liberty’s officers and directors to continued indemnification coverage and continued coverage under directors’ and officers’ liability insurance policies.

##### Table of Contents

At Liberty’s request, when Middlefield’s board approved the Reorganization Agreement it also approved the potential issuance to Liberty CEO William A. Valerian and Liberty Director Thomas W. Bevan of Middlefield common stock in the Merger. This has the effect of exempting from the application of short-swing trading principles under section 16(b) of the Securities Exchange Act of 1934 their acquisition of Middlefield common stock in the Merger. Directors of an issuer that has equity securities registered under the Securities Exchange Act of 1934 are subject to short-swing trading restrictions. Messrs. Valerian and Bevan will be Middlefield directors after the Merger.

Each of Middlefield’s and Liberty’s board of directors was aware of these interests and considered them in approving the Reorganization Agreement and the transactions contemplated therein.

The following summary reflects the opinion of Tucker Ellis LLP, legal counsel to Liberty, with respect to the material U.S. federal income tax consequences of the Merger to U.S. holders (as defined below) of Liberty common stock. The summary is based upon the Internal Revenue Code, applicable Treasury Regulations, judicial decisions and administrative rulings and practice, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. This summary does not address any tax consequences of the Merger under state, local or foreign laws, or any federal laws other than those pertaining to income tax.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner that is: an individual citizen or resident of the United States; a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions; a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person; or an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion addresses only those U.S. holders of Liberty common stock that hold their Liberty common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code and does not address all the U.S. federal income tax consequences that may be relevant to particular holders of Liberty common stock in light of their individual circumstances or to holders of Liberty common stock that are subject to special rules, such as non-U.S. holders (as defined below) (except to the extent discussed under the subheading “Tax Implications to Non-U.S. Stockholders” below); financial institutions; investors in pass-through entities; persons who are subject to alternative minimum tax; insurance companies; mutual funds; tax-exempt organizations; dealers in securities or currencies; traders in securities that elect to use a mark-to-market method of accounting; persons that hold Liberty common stock as part of a straddle, hedge, constructive sale or conversion or other integrated transaction; regulated investment companies; real estate investment trusts; persons whose “functional currency” is not the U.S. dollar; and holders who acquired their shares of Liberty common stock through the exercise of an employee stock option or otherwise as compensation.

If a partnership (or other entity that is taxed as a partnership for federal income tax purposes) holds Liberty common stock, the tax treatment of a partner in that partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in partnerships should consult their own tax advisors about the tax consequences of the Merger to them.

Tucker Ellis LLP has delivered a legal opinion, dated September 26, 2016, and filed as an exhibit to the registration statement of which this joint proxy statement/prospectus is a part, to the effect that, subject to the exceptions, qualifications and limitations set forth therein, (i) the Merger will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and (ii) Liberty and Middlefield will each be a party to such reorganization within the meaning of Section 368(a) of the Internal Revenue Code. Additionally, it is a condition to Liberty’s obligation to complete the Merger that Liberty receive an opinion from Tucker Ellis LLP, dated the closing date of the Merger, to that effect. [This condition is waivable, and Middlefield and Liberty

##### Table of Contents

undertake to recirculate and resolicit if this condition is waived and the change in tax consequences is material.] This opinion is and will be based upon representation letters provided by Middlefield and Liberty and upon customary factual assumptions. Neither Middlefield nor Liberty has sought, and neither of them will seek, any ruling from the Internal Revenue Service regarding any matters relating to the Reorganization Agreement, and the opinion described above will not be binding on the Internal Revenue Service or any court. Consequently, there can be no assurance that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which the opinion is based are inconsistent with the actual facts, the U.S. federal income tax consequences of the Merger could be adversely affected. The actual tax consequences to you of the Merger may be complex and will depend upon your specific situation and upon factors that are not within the control of Middlefield or Liberty. You should consult with your own tax advisor as to the tax consequences of the Merger in light of your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws.

The following discussion summarizes the material U.S. federal income tax consequences of the Merger to U.S. holders.

Tax Consequences of the Merger for U.S. holders of Liberty Common Stock. The U.S. federal income tax consequences of the Merger to a U.S. holder will depend on whether such U.S. holder receives cash, shares of Middlefield common stock or a combination of cash and stock in exchange for such U.S. holder’s Liberty common stock. At the time a Liberty stockholder makes a cash or stock election pursuant to the terms of the Reorganization Agreement, such stockholder will not know whether, and to what extent, the proration provisions of the Reorganization Agreement will alter the mix of consideration such stockholder will receive. As a result, the tax consequences to such stockholder will not be ascertainable with certainty until such stockholder knows the precise amount of cash and shares of Middlefield common stock that such stockholder will receive pursuant to the Merger.

Exchange of Liberty common stock solely for Middlefield common stock. Except as discussed below, see “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” a U.S. holder that exchanges all of its shares of Liberty common stock solely for shares of Middlefield common stock pursuant to the Merger will not recognize gain or loss in connection with such exchange. A U.S. holder’s aggregate tax basis in the Middlefield common stock received in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will equal such U.S. holder’s aggregate tax basis in the Liberty common stock surrendered by such U.S. holder in the Merger. The holding period for the shares of Middlefield common stock received by such U.S. holder in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will include the holding period for the shares of Liberty common stock exchanged therefor.

Exchange of Liberty common stock solely for cash. A U.S. holder who exchanges all of its shares of Liberty common stock solely for cash pursuant to the Merger generally will recognize capital gain or loss equal to the difference between the amount of cash received by such U.S. holder and the U.S. holder’s adjusted tax basis in the Liberty common stock exchanged therefor. Any capital gain or loss generally will be long-term capital gain or loss if the U.S. holder held the shares of Liberty common stock for more than one year at the effective time of the Merger.

Exchange of Liberty common stock for a combination of Middlefield common stock and cash. Except as discussed below, a U.S. holder who exchanges its shares of Liberty common stock for a combination of Middlefield common stock and cash pursuant to the Merger will recognize gain (but not loss) equal to the lesser of (i) the excess, if any, of the amount of cash plus the fair market value of any Middlefield common stock received in the merger, over such U.S. holder’s adjusted tax basis in the shares of Liberty common stock

74

##### Table of Contents

surrendered by such U.S. holder in the Merger and (ii) the amount of cash received by such U.S. holder in the Merger (other than cash received in lieu of fractional shares of Middlefield common stock).

For purposes of this calculation, the fair market value of Middlefield common stock is based on the trading price of that stock on the date of the Merger, rather than the methodology used in calculating the number of shares of Middlefield common stock to be issued to the stockholder. In the case of any U.S. holder who acquired different blocks of Liberty common stock at different times and at different prices, any realized gain or loss will be determined separately for each identifiable block of shares exchanged in the Merger. A loss realized on the exchange of one block of shares cannot be used to offset a gain realized on the exchange of another block of shares, but a U.S. holder will generally be able to reduce its capital gains by capital losses in determining its income tax liability. Prior to voting on the Merger, any U.S. holder potentially in that circumstance should consult its tax advisor with regard to identifying the basis or holding periods of the particular shares of Middlefield common stock received in the Merger. In addition, Treasury Regulations under Section 358 of the Internal Revenue Code provide that where a stockholder surrenders shares of target stock in an exchange and receives cash and shares of acquirer stock, then, to the extent the terms of the exchange specify that shares of acquirer stock or cash are received in exchange for a particular share of target stock surrendered, the terms of the exchange shall control for the purpose of determining the gain to the extent the terms of the exchange are economically reasonable. Therefore, a U.S. holder might be permitted to calculate the amount of taxable gain separately for each share of Liberty common stock surrendered in the Merger based on the specific consideration received for such share. This result might be permitted if the stockholder designates, on the election form (and as specifically authorized by the Reorganization Agreement), specific shares of Liberty common stock to be exchanged for cash or to be exchanged for Middlefield common stock, as the case may be. Such a designation might result in less taxable gain to a U.S. holder even if the holder holds a single block of Liberty common stock with a uniform tax basis. However, it is unclear whether a designation described in this paragraph will be treated as satisfying the requirements of the Treasury Regulations, and whether the proration provisions of the Merger agreement may affect such designation, and, therefore, there can be no assurance that the IRS would not successfully challenge a U.S. holder that reports taxable gain on the basis of such a designation. U.S. holders therefore should consult with their tax advisors with respect to the advisability, including any benefits or risks, of making an express designation in their election form.

Generally, a U.S. holder’s aggregate tax basis in the Middlefield common stock received by that U.S. holder in the Merger in exchange for its Liberty common stock, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” will equal such U.S. holder’s aggregate tax basis in the Liberty common stock surrendered in the Merger, increased by the amount of taxable gain (or dividend income as described in the following paragraph, but not the special dividend addressed below in “-Treatment of the Special Dividend”), if any, recognized by such U.S. holder in the Merger (other than with respect to cash received in lieu of fractional shares of Middlefield common stock), and decreased by the amount of cash, if any, received by such U.S. holder in the Merger (other than cash received in lieu of fractional shares of Middlefield common stock). The holding period for the shares of Middlefield common stock received in the Merger, including any fractional shares deemed received by the U.S. holder under the treatment discussed below in “-Cash in Lieu of Fractional Shares of Middlefield Common Stock,” generally will include the holding period for the shares of Liberty common stock exchanged therefor.

Any capital gain generally will be long-term capital gain if the U.S. holder held the shares of Liberty common stock for more than one year at the effective time of the Merger. The deductibility of capital losses is subject to limitations. All or part of the gain that a particular U.S. holder of Liberty recognizes could be treated as dividend income rather than capital gain if (i) such U.S. holder is a significant stockholder of Middlefield or (ii) such U.S. holder’s percentage ownership, taking into account constructive ownership rules, in Middlefield after the Merger is not meaningfully reduced from what its percentage ownership would have been if it had received solely shares of Middlefield common stock rather than a combination of cash and shares of Middlefield common stock in the Merger. This could happen, for example, because of ownership of additional shares of Middlefield common stock by such holder, ownership of shares of Middlefield common stock by a person related to such

75

##### Table of Contents

holder or a share repurchase by Middlefield from other holders of Middlefield common stock. These rules are complex and dependent upon the specific factual circumstances particular to each U.S. holder. Consequently, each U.S. holder that may be subject to those rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such U.S. holder.

Cash in Lieu of Fractional Shares of Middlefield Common Stock. A U.S. holder that receives cash instead of a fractional share of Middlefield common stock will be treated as having received the fractional share of Middlefield common stock pursuant to the Merger and then as having exchanged the fractional share of Middlefield common stock for cash in a redemption by Middlefield. In general, this deemed redemption will be treated as a sale or exchange, and a U.S. holder will recognize gain or loss equal to the difference between (i) the amount of cash received by such U.S. holder and (ii) the portion of the basis of the shares of Liberty common stock allocable to such fractional interest. Such gain or loss generally will constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder’s holding period for the Liberty common stock exchanged by such U.S. Holder is greater than one year as of the effective time of the Merger.

Medicare Tax on Net Investment Income. A U.S. holder that is an individual is subject to a 3.8% tax on the lesser of (i) his or her “net investment income” for the relevant taxable year or (ii) the excess of his or her modified adjusted gross income for the taxable year over a certain threshold (between $125,000 and $250,000 depending on the individual’s U.S. federal income tax filing status). A similar regime applies to estates and trusts. Net investment income generally would include any capital gain incurred in connection with the Merger, as well as the special dividend addressed below in “-Treatment of the Special Dividend.”

Backup Withholding and Information Reporting. Payments of cash to a U.S. holder of Liberty common stock pursuant to the Merger may, under certain circumstances, be subject to information reporting and backup withholding (currently at a rate of 28%) unless the holder provides proof of an applicable exemption satisfactory to Middlefield and the exchange agent or, in the case of backup withholding, furnishes its taxpayer identification number and otherwise complies with all applicable requirements of the backup withholding rules. The documents provided to Liberty stockholders to surrender their stock certificates for exchange in the Merger will provide an opportunity for the Liberty stockholder to provide required information. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

A U.S. holder of Liberty common stock, as a result of having received Middlefield common stock in the Merger, will be required to retain records pertaining to the Merger. In addition, each U.S. holder of Liberty common stock that is a “significant holder” will be required to file a statement with that holder’s U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3(b) setting forth that holder’s basis in the Liberty common stock surrendered and the fair market value of the Middlefield common stock and cash received in the Merger. A “significant holder” is a holder of Liberty common stock that, immediately before the Merger, owned at least 5% of the vote or value of the outstanding stock of Liberty or securities of Liberty with a basis for federal income taxes of at least $1 million.

Tax Implications to Non-U.S. Stockholders. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of Liberty common stock (other than an entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder. The rules governing the U.S. federal income taxation of non-U.S. holders are complex, and no attempt will be made herein to provide more than a limited summary of those rules. Any gain a non-U.S. holder recognizes from the exchange of Liberty common stock for Middlefield common stock and cash in the Merger generally will not be subject to U.S. federal income taxation unless (a) the gain is effectively connected with a trade or business conducted by the non-U.S. holder in the United States, or (b) in the case of a non- U.S. holder who is an individual, such stockholder is present in the United States for 183 days or more in the taxable year of the sale and other conditions are met. Non-U.S. holders described in (a) above will be subject to tax on gain recognized at applicable U.S. federal income tax rates and, in addition, non-U.S. holders

76

##### Table of Contents

that are corporations (or treated as corporations for U.S. federal income tax purposes) may be subject to a branch profits tax equal to 30% (or a lesser rate under an applicable income tax treaty) on their effectively connected earnings and profits for the taxable year, which would include such gain. Non-U.S. holders described in (b) above will be subject to a flat 30% tax on any gain recognized, which may be offset by U.S. source capital losses.

Treatment of the Special Dividend. The special dividend contemplated by the Reorganization Agreement is not part of the Merger consideration and is not addressed by the discussion of the Merger consideration set out above. The special dividend will be taxable to U.S. holders who are individuals as ordinary income, taxable at preferential rates applicable to “qualified dividends;” and, as discussed above in “Medicare Tax on Net Investment Income,” will be treated as “net investment income” for such purposes. Although the special dividend is not part of the Merger consideration for the purposes of the discussion above of the exchange of Liberty common stock in the Merger, the special dividend must be considered in determining whether the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. The potential amount of the special dividend has been calculated in a manner that enables Middlefield to acquire “substantially all” of the properties of Liberty within the meaning of Revenue Procedure 86-42, to be consistent with the treatment of the Merger as a “reorganization” as described in Section 368(a) of the Internal Revenue Code.

This discussion does not address tax consequences that may vary with, or are contingent upon, individual circumstances. Moreover, it does not address any non-income tax or any foreign, state or local tax consequences of the Merger. Tax matters are very complicated, and the tax consequences of the Merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local or foreign tax consequences of the Merger in light of your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws.

Accounting Treatment

The Merger will be accounted for under the acquisition method of accounting in accordance with generally accepted accounting principles in the United States. Under the acquisition method of accounting, the assets and liabilities of Liberty will be recorded and assumed at estimated fair values when the Merger is consummated. The excess of the estimated fair value of Middlefield common stock issued and the cash proceeds paid over the net fair values of the assets acquired, including identifiable intangible assets, and liabilities assumed will be recorded as goodwill and will not be deductible for income tax purposes. Goodwill is subject to an annual test for impairment and the amount impaired, if any, is charged as an expense at the time of impairment.

Resale of Middlefield Common Stock

Middlefield registered with the SEC under the Securities Act of 1933 the issuance of common stock to Liberty stockholders in the Merger. No restrictions on the sale or other transfer of Middlefield common stock issued in the Merger will be imposed solely as a result of the Merger, except for restrictions on the transfer of Middlefield common stock issued to any Liberty stockholder who becomes an affiliate of Middlefield for purposes of SEC Rule 144. The term affiliate is defined in Rule 144 and generally includes a company’s executive officers, directors, and stockholders beneficially owning 10% or more of the company’s outstanding shares.

THE REORGANIZATION AGREEMENT

Annex A is a complete copy of the Reorganization Agreement. We encourage you to read the Reorganization Agreement carefully. It is the principal legal document governing the Merger.

The Reorganization Agreement contains representations and warranties of Liberty and Middlefield. The assertions within those representations and warranties are qualified by information contained in confidential disclosure schedules the parties delivered to each other when they executed the Reorganization Agreement. In addition, some of the representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from the standard of materiality generally applicable to statements made by a corporation to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts, or for any other purpose, at the time they were made or otherwise.

Effects of the Merger

When Liberty merges into The Middlefield Banking Company, The Middlefield Banking Company will be the surviving company. The separate corporate existence of Liberty will cease and the articles of incorporation and code of regulations of The Middlefield Banking Company in effect immediately before the Merger will be the articles of incorporation and code of regulations of the surviving company. The directors and officers of The Middlefield Banking Company immediately before the Merger will be the directors and officers of the surviving company. Liberty stockholders receiving cash Merger consideration only will not participate in Middlefield’s future earnings and potential growth, but also will not bear the risk of loss for the surviving company’s business or the risk of decreases in the value of that business. Liberty stockholders receiving Middlefield common stock as Merger consideration will participate in the surviving company’s future earnings and potential growth through their ownership of stock, with all other rights associated with ownership of Middlefield common stock, such as the right to dividends and the right to vote at annual and special meetings.

Effective Time of the Merger

The Merger will occur on a date to be specified by Middlefield and Liberty within five days after all necessary closing condition are satisfied unless otherwise agreed. The conditions include receipt of all regulatory and stockholder approvals and expiration of all regulatory waiting periods. The Merger will become effective as of the date specified in the certificate of Merger to be filed with the Ohio Secretary of State. As of the date of this joint proxy statement/prospectus, assuming regulatory approvals are obtained without significant delay, the parties expect that the Merger will be effective by the end of 2016. However, Liberty and Middlefield cannot assure you that all necessary conditions to the Merger will be satisfied or when they will be satisfied.

If the Merger is not completed by May 30, 2017, the Reorganization Agreement may be terminated by Middlefield or by Liberty, unless the failure of the closing to occur by that date is due to the failure of the party seeking to terminate the Reorganization Agreement to perform or observe its covenants and agreements in the Reorganization Agreement. Either party may also terminate for uncured breaches of representations, warranties or covenants sufficient to cause a failure of a closing condition; for failure of the other party to obtain stockholder approval of the Merger; for failure to obtain regulatory approval; or in the event the Merger has not been completed by May 30, 2017. The parties may mutually agree to extend the May 30, 2017 deadline. If regulatory approvals are obtained, the terms of approval are likely to impose a deadline of six months to one year for completion of the approved transaction.

As part of the Merger transaction, MBC Interim Bank, a wholly owned interim bank subsidiary of Middlefield formed for the sole purpose of facilitating the Merger, will first merge into Liberty, with Liberty as the surviving company, followed immediately by Liberty’s merger into The Middlefield Banking Company.

Merger Consideration

When the Merger is completed, Liberty stockholders will receive from Middlefield a combination of cash and Middlefield common stock. Subject to allocation procedures in the Reorganization Agreement ensuring that approximately 45% of the outstanding Liberty common stock is converted into the right to receive Middlefield common stock and the remaining outstanding Liberty common stock is converted into the right to receive cash, at the effective time of the Merger Liberty common stock not owned by Middlefield will be converted into the right to receive either:

| • |  | $37.96 in cash, or

| • |  | 1.1934 shares of Middlefield common stock

Liberty common stockholders may elect to receive cash, stock, or a mix of cash and stock, subject to adjustment such that 45% of the Liberty shares exchanged in the Merger are exchanged for Middlefield common stock.

It is not part of the Merger consideration, but the Reorganization Agreement also provides that Liberty will declare a special dividend to its stockholders before the Merger closing. The special dividend is currently estimated to be approximately $3.0 million in the aggregate, or $3.13 per share. Middlefield will not receive Merger consideration for its 23,218 Liberty shares but it will be entitled to the special dividend payment.

Liberty stockholders will own approximately 18.7% of the outstanding Middlefield common stock after the Merger.

Middlefield will not issue fractional shares. A holder of Liberty common stock who would otherwise be entitled to a fractional share (after taking into account all Liberty common stock owned by the holder at the effective time of the Merger) will instead receive cash, without interest, in an amount equal to the product of the fractional share to which the holder would otherwise be entitled multiplied by the volume-weighted average closing sale price of Middlefield common stock for the 30 trading days immediately before the effective time.

Once the Merger is complete, the Exchange Agent will mail to each holder of Liberty common stock transmittal materials and instructions for delivering share certificates to the Exchange Agent. American Stock Transfer & Trust Company, LLC will act as Exchange Agent. Liberty stockholders must use the letter of transmittal to exchange Liberty share certificates for Merger consideration. Do not send in share certificates with your proxy form.

Treatment of Liberty Stock Options

Liberty’s compensation arrangements for officers and employees include equity-based awards, including stock options and phantom awards. There are option awards outstanding for 89,561 shares, all of which are vested. At the effective time of the Merger each outstanding and unexercised option to purchase Liberty common stock will be cancelled in exchange for a cash payment equal to (x) the positive difference, if any, between $41.09 and the exercise price of the option, multiplied by (y) the number of shares of Liberty common stock acquirable by option exercise. There are also outstanding 2,000 phantom share awards made in 2013. The phantom share awards consist of the right to a cash payment equal to the positive difference between Liberty’s stock value on December 31, 2016 and the stock value on the award date, multiplied by the number of phantom shares awarded, with value being determined by Liberty’s board of directors. The total cash payment for cancellation of the options and phantom awards is estimated be $1,147,516. The $41.09 figure is the sum of the $37.96 per share cash Merger consideration and the $3.13 per share special dividend.

Covenants and Agreements

Covenants Affecting the Conduct of Business Until the Merger Occurs. The Reorganization Agreement requires Liberty to conduct its business in the ordinary course in the period before the Merger occurs and to

79

##### Table of Contents

reasonably preserve intact its assets and business organization. Liberty is required by the Reorganization Agreement to grant Middlefield access to Liberty properties and non-confidential books and records, making internal financial information available to Middlefield as well and keeping Middlefield informed regarding Liberty’s operations as Middlefield may request. Liberty must keep Middlefield informed of material developments in its business or of any threatened litigation, meeting monthly with Middlefield personnel concerning Liberty’s operations and providing monthly reports about problem assets. Liberty will cooperate with Middlefield regarding integration of data processing and related electronic information systems. Liberty also must maintain commercially reasonable business insurance. Liberty must notify Middlefield of any stockholder litigation arising out of the Reorganization Agreement, giving Middlefield the opportunity to participate at its own expense in the defense or settlement of the litigation.

If all necessary bank regulatory approvals and stockholder approvals of the Reorganization Agreement and Merger are obtained, Liberty will declare, upon receipt of OCC approval, a special dividend payable in cash to Liberty stockholders at or before Merger closing. The amount of the special dividend is estimated to be approximately $3.0 million in the aggregate, or $3.13 per share, but under section 6.1(b) of the Reorganization Agreement, the amount can increase based on Liberty’s and Middlefield’s tax advisers’ mutual determination of the potential effect of the special dividend on the ability of Liberty’s tax counsel to render an opinion at closing that the Merger qualifies as a tax-free reorganization under Internal Revenue Code section 368(a). The Reorganization Agreement requires in section 6.1(c) that Liberty maintain Tier 1 capital of at least $28.3 million, after taking the special dividend into account but excluding the effect of identified expenses arising out of the Reorganization Agreement and Merger. For this purpose tier 1 capital is defined in OCC rules.

Liberty also agreed to a number of restrictions for the period until the Merger becomes effective, agreeing that without Middlefield’s advance consent Liberty will not –

(A) take any action that would prevent or impede the Mergers from qualifying as a reorganization under Section 368(a) of the Internal Revenue Code of 1986,

(B) change or waive any provision of Liberty’s articles of association or bylaws,

(C) issue any shares of Liberty common stock or right to acquire Liberty common stock, split, combine, or reclassify any shares of capital stock, declare, set aside, or pay a dividend, or redeem or acquire any shares of capital stock, except for shares issued upon exercise of outstanding rights, except for regular cash dividends in amounts and with payment and record dates consistent with past practice (provided that declaration and payment of the final Liberty dividend before the Effective Time is coordinated with Middlefield Banc Corp. so that holders of Liberty common stock do not receive dividends on both Liberty common stock and Middlefield Banc Corp. common stock for the same period), and except for the special dividend payable under the terms of the Reorganization Agreement,

(D) enter into, amend, or terminate a contract or agreement involving payments exceeding $25,000 over the life of the contract or agreement,

(E) apply to open a branch or automated teller facility or give notice of the intent to close a branch or automated teller facility,

(F) increase salary or wages, grant or agree to pay a bonus or severance or termination pay to, or enter into, renew, or amend an employment agreement, severance agreement, or supplemental executive agreement with, or increase the compensation or fringe benefits of, any director, officer, employee, or consultant except for (1) existing commitments, (2) bonuses, incentive payments, and salary adjustments in the ordinary course of business consistent with past practice, or (3) payments otherwise allowed by the Reorganization Agreement. Liberty will not hire or promote an employee to a rank having a title of vice president or other more senior rank or hire a new employee at an annual rate of compensation exceeding $40,000, but Liberty may hire at-will non-officer employees at an annual compensation rate not exceeding $30,000 to fill vacancies arising in the ordinary course of business. Liberty may not hire a new employee without first seeking to fill the position internally,

Middlefield has also agreed to a limited set of restrictions on its business in the period before the Merger is completed. Specifically, Middlefield has agreed that in the period before the Merger is completed it and The Middlefield Banking Company will conduct business in the usual and ordinary course, will maintain commercially reasonable business insurance, and will not take any action that –

| • |  | changes or waives a provision of its articles of incorporation or code of regulations in a way that is adverse to Liberty stockholders,

82

##### Table of Contents

| • |  | materially adversely affects the ability of the parties to obtain regulatory approval of the Merger or increases the time necessary to obtain approvals, or Middlefield’s or The Middlefield Banking Company’s ability to perform its Reorganization Agreement obligations, or results in a condition to closing not being satisfied, or

| • |  | prevents the Merger from qualifying as a tax-free reorganization under Internal Revenue Code section 368(a)

Middlefield must deposit with the Exchange Agent before Merger closing cash and Middlefield common stock sufficient to pay the Merger consideration to Liberty stockholders. Until the Merger occurs Middlefield may not issue additional shares of common stock or rights to acquire stock except under Middlefield’s equity-based benefit plans or under Middlefield’s dividend reinvestment plan. Middlefield also is required to grant Liberty access to Middlefield properties and non-confidential books and records, making internal financial information available to Liberty as well. Middlefield is also obligated to maintain insurance, supplement its disclosures to Liberty, and seek consents necessary for closing.

Nasdaq Listing. Middlefield will cause the Middlefield common stock being issued in the Merger to be authorized for listing on Nasdaq, subject to official notice of issuance, before the Merger becomes effective.

Middlefield Board of Directors. Following the Merger, the Board of Directors of Middlefield will cause two current members of the Board of Directors of Liberty, William A. Valerian and Thomas W. Bevan, to be appointed to the Board of Directors of Middlefield.

Employee Matters. Liberty employees who become employees of Middlefield or The Middlefield Banking Company when the Merger is completed will participate in employee benefit plans of general applicability to the same extent as similarly-situated employees of Middlefield and The Middlefield Banking Company, and for vesting and eligibility purposes the former Liberty employees will be credited for their service as Liberty employees. Middlefield and The Middlefield Banking Company are not contractually committed to retaining Liberty employees but have agreed to retain as many Liberty officers and employees as is commercially reasonable and possible, agreeing also to consider Liberty personnel for any positions becoming open at Middlefield or The Middlefield Banking Company after the date of the Reorganization Agreement. Middlefield will honor employment, change-in-control severance, and split dollar insurance agreements of Liberty, but is not required to pay and will not pay any benefits that would constitute parachute payments under Internal Revenue Code sections 280G and 4999. Those provisions of the Internal Revenue Code impose a 20% excise tax on parachute payments in a change in control, denying to the employer a compensation deduction for the benefits constituting parachute payments. For Liberty employees whose service does not continue after the Merger or who are terminated without cause within one year after the Merger, Middlefield has agreed in the Reorganization Agreement to pay them cash severance equal to one week of base pay for each year of service, with a minimum of four weeks of base pay and a maximum of 26, and to make available career counseling and professional counseling. Middlefield also may pay retention or incentive bonuses to selected Liberty personnel whose service is critical to the Merger-related transition, such as data processing personnel.

Indemnification and Directors’ and Officers’ Insurance. For a period ending six years after the effective time of the Merger, Middlefield will indemnify and hold harmless, to the fullest extent provided under Liberty’s articles of association and bylaws, each present and former director and officer of Liberty and its subsidiaries from liabilities arising out of or pertaining to matters existing or occurring at or before the effective time of the Merger, including the transactions under the Reorganization Agreement. Middlefield has also agreed that for a period of six years after the Merger Middlefield will maintain directors’ and officers’ liability insurance coverage for actions, omissions, or events occurring before the effective time of the Merger, including the transactions under the Reorganization Agreement, and covering Liberty directors and officers on the July 28, 2016 date of the Reorganization Agreement. The insurance will be on terms and conditions substantially equivalent to Liberty’s directors’ and officers’ liability insurance coverage, but Middlefield is not required to incur annual premium expense greater than 150% of Liberty’s annual premium cost as of July 28, 2016. Instead of Middlefield’s

83

##### Table of Contents

continued maintenance of directors’ and officers’ liability insurance coverage, before the effective time of the Merger, Middlefield may purchase and pay for a tail policy for directors’ and officers’ liability insurance on the terms described in this paragraph, or Liberty may do so with Middlefield’s consent.

Regulatory Matters. Middlefield agreed to promptly prepare and file with the SEC a registration statement on Form S-4, of which this joint proxy statement/prospectus is a part. Liberty prepared the portion of this joint proxy statement/prospectus constituting the proxy statement of Liberty. Middlefield and Liberty agreed to use commercially reasonable efforts to have the Form S-4 declared effective under the Securities Act of 1933 as promptly as practicable after such filing, and Middlefield and Liberty agreed to mail or deliver the joint proxy statement/prospectus to their respective stockholders. Middlefield also will use commercially reasonable efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to complete the Merger. Middlefield and Liberty will cooperate with each other and use commercially reasonable efforts to promptly prepare and file all necessary documentation and obtain all permits, consents, approvals, and authorizations of all third parties and governmental entities that are necessary to complete the Merger. The Reorganization Agreement requires both Middlefield and Liberty to file for all necessary regulatory approvals. See “THE MERGER – Regulatory Approvals Required.”

Stockholder Approval. Both Middlefield and Liberty are required by the Reorganization Agreement to call and hold a meeting of stockholders to enable stockholders to consider and vote on the Reorganization Agreement and the Merger. Liberty’s board of directors also committed in the Reorganization Agreement to recommend that Liberty stockholders vote in favor of adopting and approving the Reorganization Agreement, committing also to ensure that any anti-takeover provisions of Liberty’s articles of association, bylaws, or applicable state law are made inapplicable to the Merger or to minimize the impact of any applicable antitakeover provisions. The board is permitted by the Reorganization Agreement to decline to recommend a vote in favor or to withdraw, modify, or change the recommendation to stockholders if, after consultation with financial and legal advisors, the board concludes that recommending a vote in favor of adoption and approval or failing to withdraw, modify, or change the recommendation would breach the directors’ fiduciary duties to stockholders.

No Solicitation. The Reorganization Agreement prohibits Liberty and its officers, directors, employees, representatives, affiliates, and agents from (x) initiating, soliciting, knowingly encouraging, or furnishing assistance or nonpublic information for an inquiry or the making of a proposal that constitutes or that may reasonably be expected to lead to an acquisition proposal, (y) discussing, negotiating, or making a proposal that constitutes or that may reasonably be expected to lead to an acquisition proposal, or (z) agreeing to or endorsing an acquisition proposal. For this purpose the term “acquisition proposal” means a proposal or offer (other than Middlefield’s) involving Liberty for (1) merger, consolidation, share exchange, business combination, or other similar transactions, (2) sale, lease, exchange, mortgage, pledge, transfer, or other disposition of 25% or more of the assets of Liberty in a single transaction or series of transactions, or (3) a tender offer or exchange offer for 25% or more of the outstanding shares of Liberty common stock or the filing of a registration statement under the Securities Act of 1933 for the offer of shares in exchange for Liberty stock. Acquisition proposal also includes a publicly announced proposal, plan, or intention to do any of the foregoing or any agreement to engage in any of the foregoing. Liberty would not violate this obligation, however, if it furnishes information to and negotiates with a person making an acquisition proposal if two conditions are satisfied: (1) the acquisition proposal is not solicited by Liberty and (2) Liberty’s board concludes in good faith, after consulting with legal and financial advisors, that the unsolicited acquisition proposal is reasonably likely to result in a transaction more favorable to Liberty stockholders from a financial point of view than the Merger transaction under the Reorganization Agreement. A proposal satisfying both of those conditions is referred to as a “Superior Proposal.” Liberty must notify Middlefield within two business days after receiving inquiries, proposals, offers, or information requests.

Many of the representations and warranties of Liberty and Middlefield are qualified regarding “materiality” or “material adverse effect.” For purposes of the Reorganization Agreement, a “material adverse effect” means an effect that is material and adverse to the financial condition, results of operations, or business of Middlefield and its subsidiaries taken as a whole, or of Liberty and its subsidiaries taken as a whole, or materially impairs the ability of either Liberty, on one hand, or Middlefield and The Middlefield Banking Company, on the other hand, to perform the obligations under the Reorganization Agreement or otherwise materially impedes consummation of the Merger, except that the following circumstances or events are excluded when determining whether a material adverse effect has occurred:

(1) the impact of (x) changes in laws, rules, or regulations affecting banks or their holding companies generally, or interpretations thereof by courts or governmental agencies, (y) changes in GAAP, or (z) changes in regulatory accounting requirements, in any case applicable to financial institutions or their holding companies generally and not specifically relating to Liberty, on one hand, or Middlefield or any Middlefield subsidiary, on the other hand,

(2) announcement of the Reorganization Agreement by press release mutually agreed to by Liberty and Middlefield or by Form 8-K filed by Middlefield,

(3) any act or omission of Liberty required under the Reorganization Agreement or taken or omitted to be taken with the express written permission of Middlefield,

(4) any act or omission of Middlefield or The Middlefield Banking Company required under the Reorganization Agreement or taken or omitted to be taken with the express written permission of Liberty,

(5) the direct effects of compliance with the Reorganization Agreement on the operating performance of the parties, including expenses incurred by the parties investigating, negotiating, documenting, effecting, and consummating the transactions under the Reorganization Agreement,

(6) any changes after the date of the Reorganization Agreement in general economic or capital market conditions affecting banks or their holding companies generally, and

(7) any changes in national or international political or social conditions, including engagement by the United States in hostilities, whether by the declaration of a national emergency or war, or the occurrence of a military attack upon or within the United States.

The representations and warranties in the Reorganization Agreement do not survive the effective time of the Merger and, as described below under “– Termination”, if the Reorganization Agreement is terminated there will be no liability under the representations and warranties of the parties or otherwise under the Reorganization Agreement unless a party knowingly breached the Reorganization Agreement.

The Reorganization Agreement representations and warranties of Middlefield and Liberty were made solely for purposes of that agreement and as of specific dates. The representations, warranties, and covenants in the Reorganization Agreement were made for the benefit of the parties to the Reorganization Agreement only, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Reorganization Agreement instead of establishing matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those generally applicable to investors. Investors are not third-party beneficiaries under the Reorganization Agreement. When reviewing the representations, warranties, and covenants contained in the Reorganization Agreement or summarized in this joint proxy statement/prospectus, it is important to bear in mind that the representations, warranties, and covenants and the summary are not intended by the parties to the Reorganization Agreement to be characterizations of the actual state of facts or condition of

87

##### Table of Contents

Middlefield, Liberty, or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties, and covenants may have changed after the date of the Reorganization Agreement, which subsequent information might or might not be disclosed in Middlefield’ public disclosures. For the foregoing reasons, the representations, warranties, and covenants or any summary of those provisions should not be read alone and should instead be read in conjunction with the other information contained in the reports, statements, and filings that Middlefield publicly files with the SEC. For more information regarding these documents, see the section entitled “Where You Can Find More Information” in the forepart of this document.

Termination; Termination Fee

The Reorganization Agreement may be terminated before the effective time of the Merger, whether before or after approval by Liberty stockholders and Middlefield stockholders:

| • |  | by mutual written consent of Middlefield and Liberty,

| • |  | by either Middlefield or Liberty if the other party breaches its covenants or representations and warranties and the breach is not cured within 30 days after written notice, or if by its nature the breach cannot be cured, provided the terminating party is not also in breach of its covenants or representations and warranties,

| • |  | by either Middlefield or Liberty if the Merger does not occur by May 30, 2017 (or a later date the parties may agree to), unless the failure to close by that date is the result of the terminating party’s breach of covenants or representations and warranties in the Reorganization Agreement,

| • |  | by Middlefield if the Liberty stockholders do not vote to approve the Reorganization Agreement,

| • |  | by Liberty if the Middlefield stockholders do not vote to approve the Reorganization Agreement,

Liberty must pay a termination fee of $1.65 million to Middlefield if Middlefield terminates the Reorganization Agreement because Liberty’s board fails to recommend to Liberty stockholders adoption and approval of the Reorganization Agreement, or because Liberty’s board withdraws or adversely changes the recommendation in favor of the Reorganization Agreement, or because Liberty accepts a competing acquisition proposal. Liberty would also be required to pay the $1.65 million termination fee to Middlefield if Liberty terminates the Reorganization Agreement because it accepts a superior acquisition proposal. Finally, if a competing acquisition proposal is made to Liberty and thereafter Middlefield terminates the Reorganization Agreement because of a breach by Liberty or Middlefield or Liberty thereafter terminate the agreement because Liberty stockholders do not adopt and approve the Reorganization Agreement and Merger, Liberty will have to pay the $1.65 million termination fee to Middlefield if within one year after termination Liberty enters into a definitive agreement for a competing acquisition proposal.

Effect of Termination

If the Reorganization Agreement terminates, it will be deemed void, without any liability on the part of any of the parties, except in the case of a party’s willful breach of the Reorganization Agreement, and except for a

89

##### Table of Contents

potential termination fee payment by Liberty. Reorganization Agreement provisions for confidentiality of the parties’ information, the termination fee, and other technical provisions would remain effective despite termination of the Reorganization Agreement.

Amendments, Extensions and Waivers

Liberty and Middlefield may amend the Reorganization Agreement by action of their boards of directors, whether before or after stockholder approval of the Reorganization Agreement. If the amendment decreases the amount or value of Merger consideration or the form of the Merger consideration additional approval of Liberty stockholders would be necessary. At any time before effective time of the Merger a party may extend the time for performance of the other party’s obligations, waive inaccuracies in the other party’s representations and warranties, or waive compliance with agreements or conditions in the Reorganization Agreement.

Fees and Expenses

Fees and expenses incurred by a party regarding the Merger, the Reorganization Agreement, and the transactions under the Reorganization Agreement will be paid by the party incurring the fees and expenses, regardless of whether the Merger is completed, but if the Reorganization Agreement is terminated because of a party’s willful and material breach, the breaching party is liable for damages and all costs and expenses.

COMPARISON OF LIBERTY AND MIDDLEFIELD STOCKHOLDER RIGHTS

The rights of Liberty stockholders who receive Middlefield common stock in the Merger will be governed by the Ohio General Corporation Law (OGCL) and by Middlefield’s Second Amended and Restated Articles of Incorporation and Code of Regulations. Their stockholder rights currently are determined by Liberty’s Amended and Restated Articles of Association and its By-Laws. Federal law authorizing national banking associations permits national banks to select the state law that will control corporate governance questions not specifically treated in the articles of association and bylaws. Liberty’s By-Laws state that the OGCL apply.

Although the rights of Middlefield stockholders and the rights of Liberty stockholders are similar, there are some differences between provisions of the Second Amended and Restated Articles of Incorporation of Middlefield and the Amended and Restated Articles of Association of Liberty, and differences between provisions of the Amended Code of Regulations of Middlefield and the By-Laws of Liberty. The following comparison of stockholder rights is not a complete description of all differences individual Liberty stockholders might consider important. The comparison is qualified in its entirety by reference to the OGCL and the governing corporate documents of Liberty and Middlefield.

preemptive rights (the right of stockholders to purchase shares to maintain their percentage ownership interest before a corporation may sell shares to the public) |  | Liberty stockholders do not have preemptive rights |  | Middlefield stockholders do not have preemptive rights

MANAGEMENT’S DISCUSSION AND ANALYSIS OF LIBERTY BANK, N.A.’S FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

The following is a discussion and analysis of Liberty’s consolidated financial condition at June 30, 2016, December 31, 2015 and December 31, 2014 and results of operations for the six months ended June 30, 2016 and 2015 and the years ended December 31, 2015, and 2014 and should be read in conjunction with Liberty’s consolidated financial statements and notes thereto presented in this proxy statement/prospectus beginning on page F-1.

Critical Accounting Policies

Liberty’s consolidated financial statements are prepared in conformity with GAAP and follow general practices within the industry in which Liberty operates. This preparation requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions, and judgments reflected in the financial statements. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and, therefore, have a greater possibility of producing results that could be materially different from originally reported. Liberty’s management believes the following policies are both important to the portrayal of its financial condition and results of operations and require subjective or complex judgments; therefore, management considers the following to be critical accounting policies.

Allowance for Loan Losses

The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes that the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance methodology is consistent for each portfolio segment.

The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. Management estimates the allowance balance required based on past loan loss experience, information about specific borrower and loan situations, estimated collateral values, economic and other factors. Loans considered impaired are individually analyzed for impairment and required reserves are estimated for each impaired loan. A loan is considered impaired when full payment under the loan terms is not expected. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impaired amounts are generally calculated using the fair value of the collateral for

the loan. Troubled debt restructurings are considered to be collateral dependent; the loans are reported at the fair value of the collateral. For troubled debt restructurings that subsequently default, Liberty determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses.

The general component of the reserve covers non-impaired loans and is based on historical loss experience adjusted for current factors. Nonimpaired loans are grouped into pools by loan risk ratings and each pool is further segmented by primary collateral type. Loss rates are determined based on historical loss rates and applied to each loan pool using a loss migration analysis. The loss migration analysis tracks the loss experience for pools of loans over a period of time. Historical loss rates consider the most recent 60 months. The estimated reserve required based on historical loss rates are then considered for adjustment based on current qualitative and economic factors that management believes may cause future loss experiences to differ from actual historical loan loss experience. The key qualitative and economic factors considered include nature and volume of the loan portfolio, volume and severity of past due and classified loans, concentration of credit, lending policies and procedures, national and local economic and business conditions, experience of lending staff and management, quality of the loan review system, value of underlying collateral for collateral dependent loans, and other external factors. Although allocations of the allowance may be made for specific loans and loan portfolio segments, the entire allowance is available for any loan or loan portfolio segment that in management’s judgment should be charged off. Management believes it has established an allowance for probable loan losses as appropriate under GAAP.

Securities

Liberty classifies its debt securities as held to maturity when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available for sale when they might be sold before maturity. Securities classified as held to maturity are recorded at cost or amortized cost. Available for sale securities are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss). Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are calculated based on market prices of similar securities. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these securities could differ from the estimated amounts, thereby affecting Liberty’s financial position, results of operations and cash flows. If the estimated value of a security is less than the cost or amortized cost, Liberty evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of the security. If such an event or change has occurred and Liberty determines that the impairment is other-than-temporary, Liberty expenses the impairment of the security in the period in which the event or change occurred.

Interest income includes amortization of purchase premium or accretion of discount. Premiums and discounts are recognized in interest income using the level-yield method without anticipating prepayments except for mortgage-backed and collateralized mortgage obligation securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

Income Taxes

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for temporary differences between the financial reporting basis and the tax basis of Liberty’s assets and liabilities and expected benefits of operating loss carryforwards and credit carryforwards. Deferred taxes are recognized for the estimated taxes ultimately payable or recoverable based on enacted tax laws. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Changes in enacted tax rates and laws are reflected in the financial statements in the periods in which they occur.

##### Table of Contents

Liberty recognizes a tax position as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, including resolution of the related appeals or litigation processes. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Liberty recognizes interest and penalties related to income tax matters in income tax expense.

Fair Value

Fair values of impaired loans, other real estate owned, and other financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note in Liberty’s audited consolidated financial statements. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

Results of Operations

General

Liberty operates under a national charter and provides full banking services. Liberty is subject to regulation by the OCC and the FDIC. Liberty has branches in Beachwood, Solon, and Twinsburg, Ohio; Liberty’s administrative office is located in Beachwood, Ohio.

The profitability of Liberty’s operations depends primarily on its net interest income after provision for loan losses, which is the difference between interest earned on interest earning assets and interest paid on interest bearing liabilities less provision for loan losses. The provision for loan losses is dependent on changes in Liberty’s loan portfolio and management’s assessment of the collectability of Liberty’s loan portfolio as well as prevailing economic and market conditions. Liberty’s net income is also affected by noninterest income, non-interest expense and income tax expense

Net Income

Liberty had net income of approximately $1.1 million for the six months ended June 30, 2016 compared to net income of $768 thousand for the six months ended June 30, 2015. Fully diluted earnings per common share were $1.14 for the six months ended June 30, 2016 compared to $0.80 for the six months ended June 30, 2015.

The $332 thousand increase in earnings from the six months ended June 30, 2015 to the six months ended June 30, 2016 was primarily due to an increase of $822 thousand in net interest income offset by a $376 thousand increase in non-interest expense.

Liberty had net income of approximately $1.8 million for the year ended December 31, 2015 compared to net income of $3.0 million for the year ended December 31, 2014. Fully diluted earnings per common share were $0.19 for the year ended December 31, 2015 compared to $0.33 for 2014.

The $1.2 million decrease in earnings from the year ended December 31, 2014 to the year ended December 31, 2015 was primarily due to a negative provision for loan losses in the amount of $917 thousand, a decrease in net interest income and a decrease in the amount of gains recognized on the sale of education loans and SBA loans.

Net interest income increased $822 thousand during the six months ended June 30, 2016 compared to the six months ended June 30, 2015. The increase in net interest income was primarily due to an increase in loan volume and loan rate, an increase in income from investments and a decrease in interest expense. The net interest margin, expressed on a fully tax equivalent basis, was 3.99% for the six months ended June 30, 2016 and 3.57% for the six months ended June 30, 2015. The increase in the margin was primarily due to increased yields on loans.

Volume and Rate Analysis of Net Interest Income

The following table presents the extent to which changes in volume and interest rates of interest earning assets and interest bearing liabilities have affected interest income and interest expense during the periods indicated. Information is provided in each category with respect to (i) changes attributable to changes in volume (changes in volume multiplied by prior period rate), (ii) changes attributable to changes in rates (changes in rates multiplied by prior period volume) and (iii) change attributable to a combination of changes in rate and volume (change in rates multiplied by the changes in volume). Changes attributable to the combined impact of volume and rate have been allocated proportionately to the changes due to volume and the changes due to rate.

Asset Quality

On a monthly basis, Liberty’s board of directors monitors all loan portfolio activity including levels of concentrations. Liberty’s asset quality management includes strong underwriting characteristics, conservative interest rates to known customers and a comprehensive risk rating component. The Liberty directors who serve on the board loan committee participate in the credit approval process. Liberty’s loan officers have no individual loan authority. Liberty’s lending philosophy is to invest in relationships in its local markets in order to provide for sound, profitable growth and support the credit needs of these markets.

(1) | At June 30, 2016 and 2015, December 31, 2015, 2014, 2013, 2012 and 2011 the totals include $-0-, $954,196, $926,975, $119,629, $357,178, $1,130,202, and $288,384, respectively, in TDRs that are less than 90 days past due but included with non-accrual loans.

(2) | At June 30, 2016, the total includes $913,065 in TDRs which are more than 90 days past due and included with non-accrual loans.

Non-performing loans include loans accounted for on a non-accrual basis and accruing loans contractually past due 90 days or more as to interest or principal. Management reviews the loan portfolio for problem loans on an ongoing basis. During the ordinary course of business, management becomes aware of borrowers that may not be able to meet the contractual requirements of loan agreements. These loans are placed under close supervision with consideration given to placing the loan on non-accrual status, increasing the allowance for loan losses and (if appropriate) partial or full charge-off. After a loan is placed on non-accrual status, any interest previously accrued but not yet collected is reversed against current income. Generally, interest received on non-accrual loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans will not be placed back on accrual status unless back interest and principal payments are made. Liberty’s general policy is to place consumer loans 90 days past due on non-accrual status, as well as those loans that continue to pay, but display a well-defined material weakness.

Non-performing assets consists of non-performing loans as well as other repossessed assets and other real estate owned. Other real estate owned represents properties acquired through foreclosure or other proceedings and is recorded at fair value less the estimated cost of disposal at the date of acquisition. Other real estate owned is evaluated regularly to ensure that the recorded amount is supported by its current fair value. Valuation allowances to reduce the carrying amount to fair value less estimated costs of disposal are recorded as necessary. At June 30, 2016, December 31, 2015 and December 31, 2014, Liberty held other real estate which was being carried at $-0-, $-0-, and $211,500, respectively. Sale of real estate owned resulted in a gain of $97,360 in 2015. No real estate owned was sold during the six months ended June 30, 2016 or in 2014.

Classified Assets. Federal regulations provide for the classification of loans and other assets, such as debt and equity securities considered by the OCC to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific allowance for loan losses is not warranted. Assets that do not currently expose the insured institution to

105

##### Table of Contents

sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” by management. At June 30, 2016, Liberty had $399,719 of loans designated by management as “special mention,” and $2.9 million of loans designated as “substandard.”

When an insured institution classifies problem assets as either substandard or doubtful, it may establish general allowances in an amount deemed prudent by management to cover losses that are both probable and reasonable to estimate. General allowances represent allowances which have been established to cover accrued losses associated with lending activities that were both probable and reasonable to estimate, but which, unlike specific allowances, have not been allocated to particular problem assets. When an insured institution classifies problem assets as “loss,” it is required either to establish a specific allowance for losses equal to 100% of that portion of the asset so classified or to charge-off such amount. An institution’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by the regulatory authorities, which may require the establishment of additional general or specific allowances.

In connection with the filing of periodic regulatory reports and in accordance with Liberty’s classification of assets policy, Liberty regularly reviews the problem loans in its portfolio to determine whether any loans require classification in accordance with applicable regulations. Loans are listed on the “watch list” initially because of emerging financial weaknesses even though the loan is currently performing as agreed, or delinquency status, or if the loan possesses weaknesses although currently performing. If a loan deteriorates in asset quality, the classification is changed to “special mention,” “substandard,” “doubtful” or “loss” depending on the circumstances and the evaluation. Management reviews the status of each loan on the classified list on a monthly basis with the full board of directors.

The following table sets forth the amounts of classified loans and loans designated as special mention as of June 30, 2016, and December 31, 2015, 2014, 2013 and 2012.

Maturities and Sensitivities of Loans to Changes in Interest Rates

Liberty’s exposure to interest rate risk is managed by ALCO, which is composed of certain members of the Liberty board, in accordance with policies approved by the Liberty board. The ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale activities, and the maturities of investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow flexibility, maturities of deposits and consumer and commercial deposit activity. Management uses two methodologies to manage interest rate risk: (i) an analysis of relationships between interest-earning assets and interest-bearing liabilities; and (ii) an interest rate shock simulation model.

Liberty uses an interest rate risk simulation model and shock analysis to test the interest rate sensitivity of net interest income and the balance sheet, respectively. Contractual maturities and repricing opportunities of

106

##### Table of Contents

loans are incorporated in the model as are prepayment assumptions, maturity data and call options within the investment portfolio. Assumptions based on past experience are incorporated into the model for nonmaturity deposit accounts.

Liberty utilizes both static and dynamic balance sheet rate shocks to estimate the potential impact on net interest income of changes in interest rates under various rate scenarios. This analysis estimates a percentage of change in the metric from the stable rate base scenario versus alternative scenarios of rising and falling market interest rates by instantaneously shocking a static balance sheet. The following table summarizes the simulated change in net interest income over a 12-month horizon as of June 30, 2016 using a static balance sheet:

Change in Interest Rates (Basis Points) |  | Percent Change in Net Interest Income
+400 |  | (3.96)%
+300 |  | (3.11)
+200 |  | (2.44)
+100 |  | (1.61)
Base |  | 0.0
–100 |  | 0.47

The following table summarizes the simulated change in net interest income over a 12-month horizon as of June 30, 2016 using a dynamic balance sheet:

Change in Interest Rates (Basis Points) |  | Percent Change in Net Interest Income
+400 |  | (1.95)%
+300 |  | (1.59)
+200 |  | (1.42)
+100 |  | (1.08)
Base |  | 0.0
–100 |  | 0.19

The results are primarily due to behavior of demand, money market and savings deposits during such rate fluctuations. Liberty has found that, historically, interest rates on these deposits change more slowly than changes in the discount and federal funds rates. This assumption is incorporated into the simulation model and is generally not fully reflected in a gap analysis. The assumptions incorporated into the model are inherently uncertain and, as a result, the model cannot precisely measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual results will differ from the model’s simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and the application and timing of various strategies.

##### Table of Contents

Although Liberty’s management believes that appropriate specific and general loan loss allowances have been established, actual losses are dependent upon future events and, therefore, further additions to the level of specific and general loan and lease loss allowances may become necessary.

Sources of Funds

General. Deposits, loan and investment security repayments and prepayments, proceeds from the sale of loans, and cash flows generated from operations are the primary sources of Liberty’s funds for lending, investing and other general purposes.

Deposits. Liberty offers a variety of deposit accounts with a range of interest rates and terms. Liberty’s core deposits consist of checking accounts, NOW accounts, money market accounts, savings accounts and certificates of deposit. These deposits are used to support Liberty’s asset base.

Liberty does not have any brokered deposits. Liberty has pledged cash in the amount of $4.5 million, $4.5 million and $4.7 million at June 30, 2016, December 31, 2015 and 2014, respectively against public fund deposits.

The following table sets forth the composition of deposits at the dates indicated:

Borrowings. Liberty had no borrowings during the period January 1, 2014 through June 30, 2016.

Off-Balance Sheet Arrangements

Liberty does not currently engage in the use of derivative instruments to hedge interest rate risks. However, Liberty is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers.

At December 31, 2015 and 2014, Liberty had commitments to extend credit and unused line of credit totaling $25.9 and $22.2 million, respectively. At June 30, 2016, Liberty had $36.5 million in commitments to

110

##### Table of Contents

extend credit and unused line of credit and $442 thousand in standby letters of credit. Commitments to extend credit are agreements to lend to a customer so long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by Liberty to guarantee the performance of a customer to a third party. Liberty uses the same credit policies in establishing commitments and issuing letters of credit as it does for on-balance sheet instruments.

Liquidity

Liquidity is the ability to meet present and future financial obligations through either the sale or maturity of existing assets or the acquisition of additional funds through liability management. Liquid assets include cash, federal funds sold, investments and loans maturing within one year. Liberty’s ability to obtain deposits and purchase funds at favorable rates determines its liquidity exposure. As a result of Liberty’s management of liquid assets and the ability to generate liquidity through liability funding, Liberty’s management believes that Liberty maintains overall liquidity sufficient to satisfy its depositors’ requirements and meet its customers’ credit needs.

Additional sources of liquidity available to Liberty include, but are not limited to, proceeds from principal and interest payments on loans and securities, the availability of federal funds, purchased lines from various correspondent banks and the ability to obtain deposits through the adjustment of interest rates. Growth in deposits has been sufficient to fund the majority of Liberty’s net increase in loans.

Capital Resources

At June 30, 2016 and December 31, 2015, Liberty was in compliance with all of the capital requirements as established by federal regulatory agencies.

Liberty is subject to various requirements administered by the banking regulators. Failure to maintain minimum capital requirements can cause certain mandatory action by regulators that, if taken, could have a material effect. Under capital adequacy guidelines Liberty must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Liberty’s capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk factors and other factors.

At June 30, 2016 and December 31, 2015, Liberty’s capital was categorized as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since that time that management believes would have changed Liberty’s classification as well capitalized.

The following table sets forth the actual and required regulatory capital amounts and ratios for Liberty:

|  | Actual |  |  | For Capital Adequacy Purposes |  |  | To be “Well Capitalized” Under Prompt Corrective Action Provisions |

Liberty is subject to various regulatory policies and requirements relating to the payment of dividends, including requirements to maintain capital above regulatory minimums. In general, Liberty may not pay dividends in excess of its net earnings for the most recent three years. The payment of future dividends, if any, will depend primarily upon Liberty’s earnings, financial condition and need for funds, as well as restrictions imposed by regulatory authorities regarding dividend payments and net worth requirements. Liberty paid cash dividends on its common stock in the amount of $0.40 per share for the six months ended June 30, 2016. Liberty paid cash dividends on its common stock in the amount of $0.60 per share and $0.15 per share for the twelve months ended December 31, 2015 and 2014, respectively. Based upon 959,283 shares outstanding at June 30, 2016, in connection with the Merger, Liberty expects to declare a special dividend of $3.13 per share or an aggregate of approximately $3.0 million. This may increase if any stock options are exercised before the special dividend is declared. Liberty believes that it will have sufficient liquid assets available.

Impact Of Inflation And Changing Price

The financial statements and related data presented herein have been prepared in accordance with generally accepted accounting principles in the United States of America, which require the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation. The primary impact of inflation on Liberty’s operations is reflected in increased operating costs. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than does inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

The accounting principles followed by Liberty Bank, N.A. and its subsidiaries (the “Bank”), and the methods of applying these principles, conform with accounting principles generally accepted in the United States of America (“GAAP”) and with prevailing practices within the financial services industry.

A summary of significant accounting and reporting policies applied in the presentation of the accompanying consolidated financial statements follows:

Nature of Operations

The Bank operates under a national charter and provides full banking services. The Bank is subject to regulation by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation (“FDIC”). The Bank has branches in Beachwood, Solon, and Twinsburg, Ohio; the Bank’s administrative office is located in Beachwood, Ohio.

The Bank has two operating subsidiaries. LBNA Financial LLC was formed in 2010 to reduce premiums paid on title insurance. LBNA Insurance LLC was formed in 2014 to reduce premiums paid on the Bank’s corporate insurance coverage. All intercompany accounts have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Investment Securities

Securities are classified as trading, held to maturity, or available for sale upon their acquisition. Securities classified as trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value with unrealized gains and losses recorded in current earnings. Securities held to maturity are securities that the Bank has the positive intent and the ability to hold to maturity; these securities are reported at amortized cost and adjusted for unamortized premiums and discounts. All other securities are classified as available for sale. Securities classified as available for sale are reported at fair value with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. Management determines the appropriate classification at the time of purchase. All investments have been classified as available for sale.

Gains and losses on the sale of investment securities are computed on a specific identification basis. Purchases and sales are accounted for on the trade-date or settlement-date, depending on the settlement terms.

A decline in the fair value of any available for sale security below cost that is deemed to be other than temporary results in a reduction in the carrying amount to fair value. The impairment loss is bifurcated between that related to credit loss which is recognized in noninterest income and that related to all other factors which is recognized in other comprehensive income. To determine whether an impairment is other than temporary, the Bank considers, among other things, the duration and extent to which the fair value of an investment is less than its cost, changes in value subsequent to year end, forecasted performance of the issuer, and whether the Bank has the ability and intent to hold the investment until market price recovery.

NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Note 1. Summary of Significant Accounting Policies (Continued)

Investment Securities (Continued)

Premiums and discounts are amortized using the level-yield method.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for partial charge-offs, the allowance for loan losses, and net deferred origination fees.

Loans intended for sale are carried at the lower of cost or estimated market value determined on an aggregate basis. Net unrealized losses are recognized through a valuation allowance by a charge to income. Gains and losses on the sale of loans are determined under the specific identification method. Refer to Note 3 for disclosure related to loan balances sold during 2016 and 2015.

Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is applied against principal.

For further discussion on nonaccrual loans, impairment, and troubled debt restructurings, see Note 3.

Allowance for Loan Losses

The allowance for loan losses is management’s estimate of loan losses inherent in the loan portfolio at the consolidated statement of financial position date. The allowance for loan losses is assessed on a quarterly basis and provisions for loan losses are made in order to maintain the allowance at a level sufficient to absorb credit losses in the portfolio. Impairment evaluations are performed on loans segregated into homogeneous pools based on similarities in credit profile, product, and property types. Through the evaluation, general allowances for loan losses are assessed based on historical loan loss experience for each homogeneous pool. General allowances are adjusted to address other factors that affect estimated probable losses including the growth of the portfolio; current delinquency statistics; the credit risk grading; national, regional, and local economic factors and trends; and the relative level of individually allocated valuation allowances to the balances of loans individually reviewed. The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). Management believes the allowance is adequate.

Loan Fees

Loan fees and certain direct loan origination costs are deferred and recognized as an adjustment to interest income using the level-yield method over the contractual lives of related loans, if the loans are held for investment. When loans are paid off, the unamortized deferred loan fees or costs are immediately included in interest income. If the loans are held for sale, net deferred fees (costs) are not amortized, but rather recognized when the related loans are sold.

Real Estate Owned

Real estate owned represents real estate acquired through foreclosure or deed in lieu of foreclosure and is initially recorded at fair value less estimated costs to sell. Subsequent to acquisition, real estate owned is

Real Estate Owned (Continued)

carried at the lower of cost or fair value less estimated costs to sell. Management performs periodic evaluations, and a charge to income is recorded for any excess of the carrying value over the fair value less estimated costs to sell the property. Costs relating to holding and maintaining the property are charged to expense. The Bank held real estate which was being carried at $-0- at June 30, 2016 and December 31, 2015, respectively. Sale of real estate owned resulted in a gain of $97,360 in 2015.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Estimated lives are seven to twenty years for buildings and improvements and three to ten years for furniture, fixtures, and equipment. Costs of maintenance and repairs are charged to expense. Costs of renewals and betterments, where significant in amount, are capitalized.

Impairment of Long-Lived Assets

Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the recovery amount or estimated fair value of the assets. No events or changes in circumstances have occurred causing management to evaluate the recoverability of the Bank’s long-lived assets.

Concentration of Credit Risk

Financial instruments which potentially subject the Bank to concentrations of credit risk consist primarily of temporary cash investments. These cash deposits due from banks may exceed federally insured limits.

Pension Plan

The Bank has a Contributory Defined Contribution (“401k”) pension plan covering substantially all employees. The Bank made discretionary contributions of $-0- and $-0- to the Plan for the six months ended June 30, 2016 and 2015, respectively.

Share-Based Compensation

Compensation expense for awards of equity instruments is recognized on a straight-line basis over the requisite service period based on the grant date fair value estimated in accordance with the provisions of FASB ASC 718, Compensation – Stock Compensation. Share-based compensation expense is included in salaries and employee benefits in the consolidated statements of comprehensive income.

The grant date fair value of stock options is estimated using the Black-Scholes option-pricing model using assumptions for the expected option term, expected stock price volatility, risk-free interest rate, and expected dividend yield. Due to limited historical data on exercise of share options, the simplified method is used to estimate expected option term.

Note 1. Summary of Significant Accounting Policies (Continued)

Bank-Owned Life Insurance

The Bank owns insurance on the lives of a certain group of ex-employees who at one time were key employees of the Bank. The policies were purchased in 2002 and 2003 to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset in the consolidated statements of financial condition and any increases in the cash surrender value are recorded as noninterest income in the consolidated statements of comprehensive income. In the event of the death of an insured individual under these policies, the Bank would receive a death benefit, which would be recorded as noninterest income.

Per Share Information

Basic earnings per share is computed by dividing net income (loss) by the weighted average shares of common stock outstanding. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution, if any, of unexercised stock options that could occur if stock options were exercised and converted into common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method.

Federal Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Bank recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Bank believes that it has appropriate support for any tax positions taken and, as such, does not have any uncertain tax positions that are material to the consolidated financial statements.

Cash Flow Information

The Bank has defined cash equivalents as those amounts due from depository institutions and federal funds sold.

The Bank paid interest on deposits and FHLB advances of $431,879 and $494,091 in the six month periods ending 2016 and 2015, respectively.

The Bank had income tax payments of $41,800 and $1,039,801 in the six month periods ended 2016 and 2015, respectively.

Subsequent Events

Management has evaluated the events and transactions through September 30, 2016, which is the date the consolidated financial statements were available to be issued, for potential recognition or disclosure herein. There were none noted.

The amortized cost and estimated fair values of securities available for sale are as follows:

Total |  | $ | 697,207 |  |  | $ | 1 |  |  | $ | — |  |  | $ | 697,208 |

There were no sales from the investment securities available for sale portfolio during the six month periods ended June 30, 2016 and 2015.

The unrealized losses on investment securities were attributable to market rate increases. The contractual terms of these investments do not permit the issuer to settle the security at a price less than the par value of the investment.

The Bank performs a periodic assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment pursuant to FASB ASC Topic 320, Investments – Debt and Equity Securities. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The accounting literature requires the Bank to assess whether the unrealized loss is other-than-temporary. Since the decline in value is attributable to changes in interest rates and not credit quality and because the Bank has both the intent and ability to hold such securities for a time necessary to recover the amortized cost, these investments are not considered other-than-temporarily impaired.

The amortized cost and estimated fair values of investment securities available for sale at June 30, 2016 and December 31 2015, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because certain securities contain provisions which permit the issuer to repay, at par, the obligation prior to the stated maturity.

Note 2. Securities Available for Sale (Continued)

No securities available for sale at June 30, 2016 and 2015 were pledged to secure deposits, borrowings and other purposes as required by law.

Note 3. Loans

Major classifications of loans are summarized as follows:

|  | 2016 |  |  | 2015 |
Commercial |  | $ | 36,506,232 |  |  | $ | 34,633,003 |

Net loans |  | $ | 184,369,683 |  |  | $ | 176,388,405 |

The Bank grants consumer, commercial, and residential loans to customers throughout its market area, which is concentrated in Cuyahoga and Summit counties of Ohio. Although the Bank has a diversified loan portfolio at December 31, 2015 and 2014, a substantial portion of its debtors’ ability to honor their loan agreements is dependent upon the economic stability of its immediate trade area.

Sale of education loans resulted in gains of $190,278 and $67,716 in the six months ended June 30, 2016 and 2015, respectively. Sale of Small Business Administration loans resulted in gains of $-0- and $71,442 in the six months ended June 30, 2016 and 2015, respectively. Sale of residential real estate mortgage loans resulted in gains of $48,379 and $58,175 in the six months ended June 30, 2016 and 2015, respectively.

Impaired Loans

A loan is considered impaired when it is probable that not all principal and interest amounts will be collected according to the loan contract. Residential mortgage, education less than 90 days past due, and consumer loans are evaluated collectively for impairment. Individual commercial and commercial real estate loans are evaluated for impairment. Impaired loans are written down by the establishment of a specific allowance where necessary. The Bank estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan losses is maintained for estimated losses. If a loan is impaired, a portion of the allowance is allocated to that loan, equal to the excess of the loan’s carrying value over the fair value of the collateral or the excess of the loan’s carrying value over the present value of expected future cash flows. The Bank charges off principal at the earlier of (i) when a total loss of principal has been deemed to have occurred as a result of the book value exceeding the fair value or net realizable value or (ii) when collection efforts have ceased.

A loan modification in which the borrower is experiencing financial difficulties and is granted a concession without commensurate financial, structural, or legal consideration is classified as a troubled debt restructuring (“TDR”). All commercial and consumer loan TDRs, regardless of size, are evaluated for

impairment individually to determine the probable loss content and are assigned a specific loan allowance if deemed appropriate. Loan modifications are handled on a case by case basis and are negotiated to achieve mutually agreeable terms that maximize loan collectability and meet the client’s financial needs. After one year, a loan is no longer included in the balance of impaired loans if the loan was modified to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement. No troubled debt restructurings were reclassified out of impaired loans during the six months ended June 30, 2016 and 2015. At June 30, 2016, one residential real estate loan totaling $913,065 was classified as a TDR. At December 31, 2015, one residential real estate loan totaling $926,975 was classified as a TDR.

Credit Risk Grading

Sound credit systems, practices, and procedures such as credit risk grading systems; effective credit review and examination processes; effective loan monitoring, problem identification, and resolution processes; and a conservative loss recognition process and charge-off policy are integral to management’s proper assessment of the adequacy of the allowance. Many factors are considered when grades are assigned to individual loans and portfolio segments such as current and past delinquency, financial statements of the borrower, current net realizable value of collateral, and the general economic environment and specific economic trends affecting the loan portfolio.

The allowance for loan losses represents the amount which management estimates is adequate to provide for probable loan losses inherent in its loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan losses, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. While management uses the best information available to make these evaluations, future adjustments to the allowance may be necessary if economic conditions change substantially from the assumptions used in making the evaluations. Future adjustments to the allowance may also be required by regulatory examiners based on their judgments about information available to them at the time of their examination. Management believes the allowance is adequate.

Note 6. Investments in Federal Reserve Bank and Federal Home Loan Bank

The Federal Reserve Bank (“FRB”) and Federal Home Loan Bank (“FHLB”) stocks are restricted investments because they may only be sold back to the FRB and FHLB, respectively. These investments are carried at par value.

Note 7. Time Deposits

Time deposits include certificates of deposit in denominations of $100,000 or more that aggregated $21,210,656 and $24,400,951 at June 30, 2016 and December 31, 2015, respectively. Such deposits represented approximately 53% and 53% of the Bank’s total time deposits as of June 30, 2016 and December 31, 2015, respectively.

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act was signed into law, which, in part, permanently increased the maximum amount of deposit insurance to $250,000 per depositor, retroactive to January 1, 2009.

Certificates of deposit in denominations of $250,000 or more aggregated $4,885,891 and $5,694,618 at June 30, 2016 and December 31, 2015, respectively. Such deposits represented approximately 12% and 12%, respectively, of the Bank’s total time deposits.

The Bank does not have any brokered deposits. The Bank has pledged cash in the amount of $4.5 million and $4.5 million at June 30, 2016 and December 31, 2015, respectively, against public fund deposits.

At June 30, 2016, scheduled maturities of certificates of deposit are as follows:

Note 8. Federal Home Loan Bank Advances

The Bank had no advances from the FHLB at June 30, 2016 and December 31, 2015.

Note 9. Regulatory Matters

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the OCC that, if undertaken, could have a direct material effect on the consolidated financial statements of the Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in table below) of common equity Tier 1, Tier 1, and Total capital (as defined in the regulations) to risk-weighted assets (as defined) and Tier 1 capital (as defined) to average assets (as defined). The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet assets to broad risk categories.

Federal bank regulators apply certain ratios to assign FDIC-insured depository institutions to one of five categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” At June 30, 2016 and December 31, 2015, the Bank exceeded all regulatory capital requirements and is considered “well capitalized” under regulatory guidelines.

Events beyond management’s control, such as fluctuations in interest rates or a downturn in the economy in areas in which the Bank’s loans and securities are concentrated, could adversely affect future earnings and, consequently, the Bank’s ability to meet its future capital requirements.

Note 11. Related Party Transactions

In the normal course of business, loans are extended and deposit relationships incurred with directors, executive officers, and their associates. In management’s opinion, all of these transactions are on substantially the same terms and conditions as those with other individuals and businesses of comparable creditworthiness and deposit activity.

A summary of loan activity for these related parties, as defined, for the six month periods ended June 30, 2016 and 2015 is as follows:

January 1, 2016 |  | Additions |  | Amounts Collected |  | June 30, 2016
$3,660,438 |  | $— |  | $42,140 |  | $3,618,298
January 1, 2015 |  | Additions |  | Amounts Collected |  | June 30, 2015
$2,904,694 |  | $230,000 |  | $166,619 |  | $2,968,075

Deposits of related parties amounted to approximately $28.3 million or 14.88% and $15.9 million or 8.8% of the Bank’s total deposits as of June 30, 2016 and December 31, 2015, respectively.

Note 12. Commitments

In the normal course of business, the Bank enters into commitments with off-balance-sheet risk to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments totaled $36.9 and $25.9 million at June 30, 2016 and December 31, 2015, respectively.

Commitments to extend credit involve elements of credit risk and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the commitment is represented by the contractual amount of the commitment. The Bank generally uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Interest rate risk on commitments to extend credit results from the possibility that interest rates may have moved unfavorably from the position of the Bank since the time the commitment was made. These commitments are comprised primarily of available commercial and personal lines of credit and unfunded loans which have been authorized for disbursement.

The Company leases its administrative office, certain of its branches, and certain equipment under renewable operating lease agreements. Future minimum payments under noncancelable operating leases with initial or remaining terms of one year or more consisted of the following at June 30, 2016:

Year |  | Amount |
2016 |  | $ | 158,743 |
2017 |  |  | 317,319 |
2018 |  |  | 311,127 |
2019 |  |  | 308,468 |
2020 |  |  | 296,205 |
Thereafter |  |  | 1,233,243 |

Note 12. Commitments (Continued)

Lease payments charged to operations for the six months ended June 30, 2016 and 2015 were $158,535 and $172,908, respectively.

The Bank is involved in litigation and is subject to certain claims that arise in the normal course of operations. In the opinion of management, the ultimate disposition of the litigation and claims will not have a material adverse effect on the Bank’s operations or financial position.

Note 13. Issuance of Common Stock

During 2016 and 2015, the Board approved the issuance of 1,677 and 2,868 shares totaling $52,976 and $86,585, respectively, as incentive compensation to four executive officers and one senior officer of the Bank. Also during 2015, two (2) employees exercised 8,011 outstanding stock options totaling $211,890.

Note 14. Stock Option Plan

At June 30, 2016, the Bank had three stock option plans under which shares of common stock are reserved for grant to officers and employees. All of the Bank’s plans have been approved by the Bank’s stockholders. The Bank believes that such awards better align the interests of its employees with those of its stockholders.

Option awards are granted with an exercise price at the fair market value of the Bank’s stock at the date of grant and generally vest over three years. The date on which the options are first exercisable is determined by a committee of the Board of Directors. The options expire no later than ten years from the grant date.

GAAP requires that stock options be recognized as compensation expense based on their fair value over the vesting period. The Bank recognized stock option compensation expense of $1,337 and $3,360 in the six months ended in 2016 and 2015, respectively. The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model using the assumptions noted in the following table. Expected volatilities are based upon implied volatilities from traded options on stock, historical volatility, and other factors that affect the Bank and similar financial institutions. The Bank uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that the options granted are expected to be outstanding. The risk free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. There were no options granted in 2016 or 2015.

|  | 2013 |
Volatility |  |  | 34 | %
Expected dividends |  |  | — |
Expected term (in years) |  |  | 10 |
Risk-free rate |  |  | 1.92 | %

The total fair value of shares vested during the year ended December 31, 2015 was approximately $15,676. There were no options granted during the year 2015. The total intrinsic value of options exercised during the year ended December 31, 2015 was $90,504. The Bank has 98,000 shares remaining available for grant under the stock option plans.

As of June 30, 2016, there was $-0- unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of five years.

Note 15. Line of Credit

At June 30, 2016, the Bank has $3.0 million available under the terms of a federal funds line of credit, which is used for daily or short-term cash needs. No amounts have been drawn on the line during the six month periods ended in 2016 and 2015.

Note 16. Fair Value of Financial Instruments

The carrying values of cash and due from banks, federal funds sold, accrued interest and other assets, and accrued interest and other liabilities are reasonable estimates of fair value due to the short-term nature of these financial instruments.

The Bank estimates the fair value of financial instruments using available market information and other generally accepted valuation methodologies. Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The three levels of inputs are defined as follows:

Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets.

Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with few transactions, or model-based valuation techniques using assumptions that are observable in the market.

Level 3 – Unobservable inputs in which little or no market data exists.

The asset’s fair value measurement level is based on the lowest level of any input that is significant to the fair value measurement.

|  | June 30, 2016 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Assets |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Securities available for sale |  | $ | 697,208 |  |  | $ | 407 |  |  | $ | 696,801 |  |  | $ | — |

Level 1 securities are investments in U.S. agency securities in other banks. Level 2 investments are certificates of deposit.

Note 16. Fair Value of Financial Instruments (Continued)

The following table presents estimated fair value of the Bank’s financial instruments. The estimated fair value amounts have been determined by the Bank using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Bank could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Cash, deposits with banks, and federal funds sold – The carrying amount is a reasonable estimate of fair value.

Securities available for sale – Estimated fair value for investments and mortgage-backed securities is based on quoted market prices, dealer quotes, and prices obtained from independent pricing services at the consolidated statement of financial condition date.

Loans – Fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Accrued interest and other assets – The carrying amount is a reasonable estimate of fair value.

Cash value of life insurance – The carrying amount is a reasonable estimate of fair value.

Investments in FRB and FHLB – The fair value is estimated to be the carrying value which is par. All transactions in the capital stock of the FRB and the FHLB are executed at par.

Deposits – The fair value of demand deposits, savings accounts, and money market deposit accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificate of deposit is estimated by discounting the future cash flows and rates currently offered for deposits of similar remaining maturities.

Accrued interest and other liabilities – The carrying amount is a reasonable estimate of fair value.

Independent Auditors’ Report

To the Board of Directors and Stockholders

Liberty Bank, N.A.

Beachwood, Ohio

We have audited the accompanying consolidated financial statements of Liberty Bank, N.A. and its subsidiaries, which comprise the consolidated statements of financial condition as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, changes in stockholders’ equity, and cash flows for the three years in the period ended December 31, 2015, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Liberty Bank, N.A. and its subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for the three years in the period ended December 31, 2015 in accordance with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

The accounting principles followed by Liberty Bank, N.A. and its subsidiaries (the “Bank”), and the methods of applying these principles, conform with accounting principles generally accepted in the United States of America (“GAAP”) and with prevailing practices within the financial services industry.

A summary of significant accounting and reporting policies applied in the presentation of the accompanying consolidated financial statements follows:

Nature of Operations

The Bank operates under a national charter and provides full banking services. The Bank is subject to regulation by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation (“FDIC”). The Bank has branches in Beachwood, Solon, and Twinsburg, Ohio; the Bank’s administrative office is located in Beachwood, Ohio.

The Bank has two operating subsidiaries. LBNA Financial LLC was formed in 2010 to reduce premiums paid on title insurance. LBNA Insurance LLC was formed in 2014 to reduce premiums paid on the Bank’s corporate insurance coverage. All intercompany accounts have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Investment Securities

Securities are classified as trading, held to maturity, or available for sale upon their acquisition. Securities classified as trading are securities that are bought and held principally for the purpose of selling in the near term; these securities are reported at fair value with unrealized gains and losses recorded in current earnings. Securities held to maturity are securities that the Bank has the positive intent and the ability to hold to maturity; these securities are reported at amortized cost and adjusted for unamortized premiums and discounts. All other securities are classified as available for sale. Securities classified as available for sale are reported at fair value with unrealized gains and losses, net of tax, reported as a component of accumulated other comprehensive income. Management determines the appropriate classification at the time of purchase. All investments have been classified as available for sale.

Gains and losses on the sale of investment securities are computed on a specific identification basis. Purchases and sales are accounted for on the trade-date or settlement-date, depending on the settlement terms.

A decline in the fair value of any available for sale security below cost that is deemed to be other than temporary results in a reduction in the carrying amount to fair value. The impairment loss is bifurcated between that related to credit loss which is recognized in noninterest income and that related to all other factors which is recognized in other comprehensive income. To determine whether an impairment is other than temporary, the Bank considers, among other things, the duration and extent to which the fair value of an investment is less than its cost, changes in value subsequent to year end, forecasted performance of the issuer, and whether the Bank has the ability and intent to hold the investment until market price recovery.

Premiums and discounts are amortized using the level-yield method.

Note 1. Summary of Significant Accounting Policies (Continued)

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances adjusted for partial charge-offs, the allowance for loan losses, and net deferred origination fees.

Loans intended for sale are carried at the lower of cost or estimated market value determined on an aggregate basis. Net unrealized losses are recognized through a valuation allowance by a charge to income. Gains and losses on the sale of loans are determined under the specific identification method. Refer to Note 3 for disclosure related to loan balances sold during 2015, 2014 and 2013.

Interest income is recognized as income when earned on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest received on nonaccrual loans is applied against principal.

For further discussion on nonaccrual loans, impairment, and troubled debt restructurings, see Note 3.

Allowance for Loan Losses

The allowance for loan losses is management’s estimate of loan losses inherent in the loan portfolio at the consolidated statement of financial position date. The allowance for loan losses is assessed on a quarterly basis and provisions for loan losses are made in order to maintain the allowance at a level sufficient to absorb credit losses in the portfolio. Impairment evaluations are performed on loans segregated into homogeneous pools based on similarities in credit profile, product, and property types. Through the evaluation, general allowances for loan losses are assessed based on historical loan loss experience for each homogeneous pool. General allowances are adjusted to address other factors that affect estimated probable losses including the growth of the portfolio; current delinquency statistics; the credit risk grading; national, regional, and local economic factors and trends; and the relative level of individually allocated valuation allowances to the balances of loans individually reviewed. The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). Management believes the allowance is adequate.

Loan Fees

Loan fees and certain direct loan origination costs are deferred and recognized as an adjustment to interest income using the level-yield method over the contractual lives of related loans, if the loans are held for investment. When loans are paid off, the unamortized deferred loan fees or costs are immediately included in interest income. If the loans are held for sale, net deferred fees (costs) are not amortized, but rather recognized when the related loans are sold.

Real Estate Owned

Real estate owned represents real estate acquired through foreclosure or deed in lieu of foreclosure and is initially recorded at fair value less estimated costs to sell. Subsequent to acquisition, real estate owned is carried at the lower of cost or fair value less estimated costs to sell. Management performs periodic evaluations, and a charge to income is recorded for any excess of the carrying value over the fair value less estimated costs to sell the property. Costs relating to holding and maintaining the property are charged to

expense. The Bank held real estate which was being carried at $-0-, $211,500 and $600,000 at December 31, 2015, 2014 and 2013, respectively. Sale of real estate owned resulted in a gain of $97,360 in 2015. No real estate was sold in 2014 or 2013.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Estimated lives are seven to twenty years for buildings and improvements and three to ten years for furniture, fixtures, and equipment. Costs of maintenance and repairs are charged to expense. Costs of renewals and betterments, where significant in amount, are capitalized.

Impairment of Long-Lived Assets

Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the recovery amount or estimated fair value of the assets. No events or changes in circumstances have occurred causing management to evaluate the recoverability of the Bank’s long-lived assets.

Concentration of Credit Risk

Financial instruments which potentially subject the Bank to concentrations of credit risk consist primarily of temporary cash investments. These cash deposits due from banks may exceed federally insured limits.

Pension Plan

The Bank has a Contributory Defined Contribution (“401k”) pension plan covering substantially all employees. The Bank made discretionary contributions of $58,011, $48,227 and $-0- to the Plan for the years ended December 31, 2015, 2014 and 2013, respectively.

Share-Based Compensation

Compensation expense for awards of equity instruments is recognized on a straight-line basis over the requisite service period based on the grant date fair value estimated in accordance with the provisions of FASB ASC 718, Compensation – Stock Compensation. Share-based compensation expense is included in salaries and employee benefits in the consolidated statements of comprehensive income.

The grant date fair value of stock options is estimated using the Black-Scholes option-pricing model using assumptions for the expected option term, expected stock price volatility, risk-free interest rate, and expected dividend yield. Due to limited historical data on exercise of share options, the simplified method is used to estimate expected option term.

Note 1. Summary of Significant Accounting Policies (Continued)

Bank-Owned Life Insurance

The Bank owns insurance on the lives of a certain group of ex-employees who at one time were key employees of the Bank. The policies were purchased in 2002 and 2003 to help offset the increase in the costs of various fringe benefit plans including healthcare. The cash surrender value of these policies is included as an asset in the consolidated statements of financial condition and any increases in the cash surrender value are recorded as noninterest income in the consolidated statements of comprehensive income. In the event of the death of an insured individual under these policies, the Bank would receive a death benefit, which would be recorded as noninterest income.

Per Share Information

Basic earnings per share is computed by dividing net income (loss) by the weighted average shares of common stock outstanding. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution, if any, of unexercised stock options that could occur if stock options were exercised and converted into common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method.

Federal Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Bank recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Bank believes that it has appropriate support for any tax positions taken and, as such, does not have any uncertain tax positions that are material to the consolidated financial statements.

Cash Flow Information

The Bank has defined cash equivalents as those amounts due from depository institutions and federal funds sold.

The Bank paid interest on deposits and FHLB advances of $958,595, $1,043,107 and $1,157,445 in 2015, 2014 and 2013, respectively.

The Bank had income tax payments of $1,935,601, $-0- and $38,205 in 2015, 2014 and 2013, respectively.

The Bank had noncash activity related to loan renewals and refinancing which amounted to $15,558,650, $18,626,766 and $31,886,904 in 2015, 2014 and 2013, respectively.

Subsequent Events

Management has evaluated the events and transactions through February 25, 2016, which is the date the consolidated financial statements were available to be issued, for potential recognition or disclosure herein. There were none noted.

There were no sales from the investment securities available for sale portfolio during the years ended December 31, 2015, 2014 and 2013.

The unrealized losses on investment securities were attributable to market rate increases. The contractual terms of these investments do not permit the issuer to settle the security at a price less than the par value of the investment.

The Bank performs a periodic assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment pursuant to FASB ASC Topic 320, Investments – Debt and Equity Securities. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The accounting literature requires the Bank to assess whether the unrealized loss is other-than-temporary. Since the decline in value is attributable to changes in interest rates and not credit quality and because the Bank has both the intent and ability to hold such securities for a time necessary to recover the amortized cost, these investments are not considered other-than-temporarily impaired.

The amortized cost and estimated fair values of investment securities available for sale at December 31, 2015 and 2014, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because certain securities contain provisions which permit the issuer to repay, at par, the obligation prior to the stated maturity.

Note 3. Loans

Major classifications of loans are summarized as follows:

|  | 2015 |  |  | 2014 |
Commercial |  | $ | 34,633,003 |  |  | $ | 32,991,795 |

Net loans |  | $ | 176,388,405 |  |  | $ | 166,532,121 |

The Bank grants consumer, commercial, and residential loans to customers throughout its market area, which is concentrated in Cuyahoga and Summit counties of Ohio. Although the Bank has a diversified loan portfolio at December 31, 2015 and 2014, a substantial portion of its debtors’ ability to honor their loan agreements is dependent upon the economic stability of its immediate trade area.

Sale of education loans resulted in gains of $239,723, $434,301 and $747,301 in 2015, 2014 and 2013, respectively. Sale of Small Business Administration loans resulted in gains of $154,541, $286,787 and $275,521 in 2015, 2014 and 2013, respectively. Sale of residential real estate mortgage loans resulted in gains of $80,664, $49,710 and $53,022 in 2015, 2014 and 2013, respectively.

Impaired Loans

A loan is considered impaired when it is probable that not all principal and interest amounts will be collected according to the loan contract. Residential mortgage, education less than 90 days past due, and consumer loans are evaluated collectively for impairment. Individual commercial and commercial real estate loans are evaluated for impairment. Impaired loans are written down by the establishment of a specific allowance where necessary. The Bank estimates credit losses on impaired loans based on the present value of expected cash flows or the fair value of the underlying collateral if the loan repayment is expected to come from the sale or operation of such collateral. Impaired loans, or portions thereof, are charged off when it is determined a realized loss has occurred. Until such time, an allowance for loan losses is maintained for estimated losses. If a loan is impaired, a portion of the allowance is allocated to that loan, equal to the excess of the loan’s carrying value over the fair value of the collateral or the excess of the loan’s carrying value over the present value of expected future cash flows. The Bank charges off principal at the earlier of (i) when a total loss of principal has been deemed to have occurred as a result of the book value exceeding the fair value or net realizable value or (ii) when collection efforts have ceased.

Note 3. Loans (Continued)

Impaired Loans (Continued)

A loan modification in which the borrower is experiencing financial difficulties and is granted a concession without commensurate financial, structural, or legal consideration is classified as a troubled debt restructuring (“TDR”). All commercial and consumer loan TDRs, regardless of size, are evaluated for impairment individually to determine the probable loss content and are assigned a specific loan allowance if deemed appropriate. Loan modifications are handled on a case by case basis and are negotiated to achieve mutually agreeable terms that maximize loan collectability and meet the client’s financial needs. After one year, a loan is no longer included in the balance of impaired loans if the loan was modified to yield a market rate for loans of similar credit risk at the time of restructuring and the loan is not impaired based on the terms of the restructuring agreement. No troubled debt restructurings were reclassified out of impaired loans during the years ended December 31, 2015, 2014 and 2013. At December 31, 2015, one residential real estate loan totaling $926,975 was classified as a TDR. At December 31, 2014, one commercial real estate loan totaling $119,629 was classified as a TDR.

Credit Risk Grading

Sound credit systems, practices, and procedures such as credit risk grading systems; effective credit review and examination processes; effective loan monitoring, problem identification, and resolution processes; and a conservative loss recognition process and charge-off policy are integral to management’s proper assessment of the adequacy of the allowance. Many factors are considered when grades are assigned to individual loans and portfolio segments such as current and past delinquency, financial statements of the borrower, current net realizable value of collateral, and the general economic environment and specific economic trends affecting the loan portfolio. Credit quality indicators used in management’s periodic analysis of the adequacy of the allowance include the Bank’s internal credit risk grades and are identified in the following table:

|  |  |  | Commercial* |  |  | Commercial Real Estate* |  |  | Total* |
Grade 1 |  | Excellent |  | $ | 1,127,370 |  |  | $ | — |  |  | $ | 1,127,370 |

Note 4. Allowance for Loan Losses

The allowance for loan losses represents the amount which management estimates is adequate to provide for probable loan losses inherent in its loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses which is charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan losses, which encompasses the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. While management uses the best information available to make these evaluations, future adjustments to the allowance may be necessary if economic conditions change substantially from the assumptions used in making the evaluations. Future adjustments to the allowance may also be required by regulatory examiners based on their judgments about information available to them at the time of their examination. Management believes the allowance is adequate.

Note 10. Regulatory Matters

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the OCC that, if undertaken, could have a direct material effect on the consolidated financial statements of the Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in table below) of common equity Tier 1, Tier 1, and Total capital (as defined in the regulations) to risk-weighted assets (as defined) and Tier 1 capital (as defined) to average assets (as defined). The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet assets to broad risk categories.

Federal bank regulators apply certain ratios to assign FDIC-insured depository institutions to one of five categories: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized.” At December 31, 2015, the Bank exceeded all regulatory capital requirements and is considered “well capitalized” under regulatory guidelines.

Events beyond management’s control, such as fluctuations in interest rates or a downturn in the economy in areas in which the Bank’s loans and securities are concentrated, could adversely affect future earnings and, consequently, the Bank’s ability to meet its future capital requirements.

Note 12. Related Party Transactions

In the normal course of business, loans are extended and deposit relationships incurred with directors, executive officers, and their associates. In management’s opinion, all of these transactions are on substantially the same terms and conditions as those with other individuals and businesses of comparable creditworthiness and deposit activity.

A summary of loan activity for these related parties, as defined, for the years ended December 31, 2015 and 2014 is as follows:

January 1, 2015 |  | Additions |  |  | Amounts Collected |  |  | December 31, 2015 |
$2,904,694 |  | $ | 955,000 |  |  | $ | 199,256 |  |  | $ | 3,660,438 |
January 1, 2014 |  | Additions |  |  | Amounts Collected |  |  | December 31, 2014 |
$1,947,640 |  | $ | 1,000,000 |  |  | $ | 42,946 |  |  | $ | 2,904,694 |

Deposits of related parties amounted to approximately $15.9 million or 8.8% and $17.2 million or 9.6% of the Bank’s total deposits as of December 31, 2015 and 2014, respectively.

Note 13. Commitments

In the normal course of business, the Bank enters into commitments with off-balance-sheet risk to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments totaled $25.9 and $22.2 million at December 31, 2015 and 2014, respectively.

Commitments to extend credit involve elements of credit risk and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the commitment is represented by the contractual amount of the commitment. The Bank generally uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Interest rate risk on commitments to extend credit results from the possibility that interest rates may have moved unfavorably from the position of the Bank since the time the commitment was made. These commitments are comprised primarily of available commercial and personal lines of credit and unfunded loans which have been authorized for disbursement.

The Company leases its administrative office, certain of its branches, and certain equipment under renewable operating lease agreements. Future minimum payments under noncancelable operating leases with initial or remaining terms of one year or more consisted of the following at December 31, 2015:

Year |  | Amount |
2016 |  | $ | 317,485 |
2017 |  |  | 317,319 |
2018 |  |  | 311,127 |
2019 |  |  | 308,468 |
2020 |  |  | 296,205 |
Thereafter |  |  | 1,233,243 |

Lease payments charged to operations for the years ended December 31, 2015, 2014 and 2013 were $272,298, $355,961 and $344,388, respectively.

The Bank is involved in litigation and is subject to certain claims that arise in the normal course of operations. In the opinion of management, the ultimate disposition of the litigation and claims will not have a material adverse effect on the Bank’s operations or financial position.

Note 14. Issuance of Common Stock

During 2015, the Board approved the issuance of 2,868 shares totaling $86,585 as incentive compensation to four executive officers and one senior officer of the Bank. Also during 2015, two (2) employees exercised 8,011 outstanding stock options totaling $211,890.

During 2014, six (6) employees exercised 43,195 outstanding stock options totaling $1,050,055.

During 2013, the Board approved the issuance of 2,582 shares totaling $70,566 as incentive compensation to four executive officers and one senior officer of the Bank.

Note 15. Stock Option Plan

At December 31, 2015, the Bank had three stock option plans under which shares of common stock are reserved for grant to officers and employees. All of the Bank’s plans have been approved by the Bank’s stockholders. The Bank believes that such awards better align the interests of its employees with those of its stockholders.

Option awards are granted with an exercise price at the fair market value of the Bank’s stock at the date of grant and generally vest over three years. The date on which the options are first exercisable is determined by a committee of the Board of Directors. The options expire no later than ten years from the grant date.

GAAP requires that stock options be recognized as compensation expense based on their fair value over the vesting period. The Bank recognized stock option compensation expense of $6,720, $15,473 and $24,800 in 2015, 2014 and 2013, respectively. The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model using the assumptions noted in the following table. Expected volatilities are based upon implied volatilities from traded options on stock, historical volatility, and other factors that affect the Bank and similar financial institutions. The Bank uses historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that the options granted are expected to be outstanding. The risk free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant. There were no options granted in 2015 or 2014.

|  | 2013 |
Volatility |  |  | 34 | %
Expected dividends |  |  | — |
Expected term (in years) |  |  | 10 |
Risk-free rate |  |  | 1.92 | %

Note 17. Fair Value of Financial Instruments

The carrying values of cash and due from banks, federal funds sold, accrued interest and other assets, and accrued interest and other liabilities are reasonable estimates of fair value due to the short-term nature of these financial instruments.

The Bank estimates the fair value of financial instruments using available market information and other generally accepted valuation methodologies. Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and a fair value framework is established whereby assets and liabilities measured at fair value are grouped into three levels of a fair value hierarchy, based on the transparency of inputs and the reliability of assumptions used to estimate fair value. The three levels of inputs are defined as follows:

Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets.

Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with few transactions, or model-based valuation techniques using assumptions that are observable in the market.

Level 3 – Unobservable inputs in which little or no market data exists.

The asset’s fair value measurement level is based on the lowest level of any input that is significant to the fair value measurement.

|  | December 31, 2015 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Assets |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Securities available for sale |  | $ | 697,208 |  |  | $ | 407 |  |  | $ | 696,801 |  |  | $ | — |
|  | December 31, 2014 |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Assets |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Securities available for sale |  | $ | 2,082,320 |  |  | $ | 1,502,050 |  |  | $ | 580,270 |  |  | $ | — |

Level 1 securities are investments in U.S. agency securities in other banks. Level 2 investments are certificates of deposit.

Note 17. Fair Value of Financial Instruments (Continued)

The following table presents estimated fair value of the Bank’s financial instruments. The estimated fair value amounts have been determined by the Bank using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Bank could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Cash, deposits with banks, and federal funds sold – The carrying amount is a reasonable estimate of fair value.

Securities available for sale – Estimated fair value for investments and mortgage-backed securities is based on quoted market prices, dealer quotes, and prices obtained from independent pricing services at the consolidated statement of financial condition date.

Loans – Fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Accrued interest and other assets – The carrying amount is a reasonable estimate of fair value.

Cash value of life insurance – The carrying amount is a reasonable estimate of fair value.

Investments in FRB and FHLB – The fair value is estimated to be the carrying value which is par. All transactions in the capital stock of the FRB and the FHLB are executed at par.

Deposits – The fair value of demand deposits, savings accounts, and money market deposit accounts is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificate of deposit is estimated by discounting the future cash flows and rates currently offered for deposits of similar remaining maturities.

Accrued interest and other liabilities – The carrying amount is a reasonable estimate of fair value.

ARTICLE 3

CONVERSION OF SHARES

3.1 Conversion of Liberty Bank Common Stock; Consideration Payable in Interim Merger; Possible Adjustment in Merger Consideration. Without any action on the part of Middlefield Banc Corp., The Middlefield Banking Company, Liberty Bank, or the holders of any of the shares of Liberty Bank common stock, at the Effective Time the Interim Merger will be effected on the following terms:

3.1.1 Each share of Middlefield Banc Corp. common stock and each share of The Middlefield Banking Company common stock issued and outstanding immediately before the Effective Time will remain issued and outstanding at the Effective Time, unchanged by the Mergers.

3.1.2 All shares of Liberty Bank common stock held in the treasury of Liberty Bank and each share of Liberty Bank common stock owned by Middlefield Banc Corp. (other than shares held in a fiduciary capacity or in connection with debts previously contracted) (the “Treasury Stock”) will at the Effective Time cease to exist. The shares of Treasury Stock, including Certificates therefor, will be canceled and no payment or distribution will be made in consideration therefor.

3.1.3 Except for Treasury Stock and Dissenting Shares and as provided in and subject to the limitations in this Agreement, by virtue of the Interim Merger, each share of Liberty Bank common stock issued and

A-10

##### Table of Contents

outstanding immediately before the Effective Time will at the Effective Time become and be converted into the right to receive at the election of the holder as provided in Section 3.2 either (i) $37.96 in cash (the “Cash Conside ration”), or (ii) 1.1934 shares (the “Exchange Ratio”) of Middlefield Banc Corp. common stock (the “Stock Consideration”). Together, the Cash Consideration and the Stock Consideration are sometimes referred to as the “Merger Consideration.” All of the 100 outstanding shares of common stock of MBC Interim Bank, no par value, shall be cancelled for no additional consideration in connection with the Interim Merger. It is understood and agreed that the Merger Consideration is subject to adjustment in the event that the special dividend payable to the Liberty Bank stockholders pursuant to Section 6.1(b) of this Agreement exceeds the sum of (i) $3,000,000 and (ii) such additional incremental amount necessary to ensure that the per share value is the same for all Liberty Bank stockholders entitled to receive it (collectively, the “Base Special Dividend”). If it is determined, upon completion of the review process outlined in Section 6.1(b) hereof and receipt of regulatory approval, that Liberty Bank will pay an amount to Liberty Bank stockholders in excess of the Base Special Dividend (the “Excess Amount”), then the Merger Consideration will be reduced by the Excess Amount, adjusted as necessary to ensure that all Liberty Bank stockholders entitled thereto receive the same per share value. Any adjustment in Merger Consideration shall be in the same form and subject to the same allocations between Middlefield Banc Corp. common stock and cash and election procedures as are specified in this Article 3.

3.1.4 Except as stated in Section 3.1.2 or Section 3.1.5, at the Effective Time outstanding shares of Liberty Bank common stock will no longer be outstanding, will be automatically canceled, will cease to exist, and will thereafter represent solely the right to receive the Merger Consideration and any dividends or distributions with a record date before the Effective Time that were declared or made by Liberty Bank on the shares of Liberty Bank common stock in accordance with the terms of this Agreement on or before the Effective Time but that remain unpaid at the Effective Time.

3.1.5 Each outstanding share of Liberty Bank common stock, the holder of which has perfected the right to dissent under the National Bank Act and has not effectively withdrawn or lost dissenters’ rights as of the Effective Time (the “Dissenting Shar e s”), will not be converted into or represent a right to receive the Merger Consideration in connection with the Interim Merger, and the holder thereof will be entitled solely to rights granted by applicable law. Liberty Bank will give Middlefield Banc Corp. immediate notice upon receipt by Liberty Bank of any demand for payment of the fair value of shares of Liberty Bank common stock and of withdrawals of demand for payment and any other related communications (any stockholder duly making a demand being hereinafter called a “Dissenting Stockholde r”). Middlefield Banc Corp. may participate in all discussions, negotiations, and proceedings relating to a demand for payment of the fair value of shares of Liberty Bank common stock. Except with advance written consent of Middlefield Banc Corp., Liberty Bank will not voluntarily make any payment on, settle or offer to settle a demand for payment, or waive a failure of timely delivery of a written demand for appraisal or of the taking of any other action by the Dissenting Stockholder as may be necessary to perfect appraisal rights under applicable law. Any payments made for Dissenting Shares will be made by the Surviving Institution.

3.1.6 If at or before the Effective Time of the Interim Merger, whether through failure to perfect or otherwise, a Dissenting Stockholder withdraws or loses the right to payment, the holder’s shares of Liberty Bank common stock will be converted into the right to receive Merger Consideration in accordance with the applicable provisions of this Agreement. If after the Effective Time of the Interim Merger, whether through failure to perfect or otherwise, a Dissenting Stockholder withdraws or loses the right to payment, each share of Liberty Bank common stock of the holder is entitled to receive the Merger Consideration.

3.1.7 Regardless of anything to the contrary in this Agreement, no certificates or scrip for fractional shares of Middlefield Banc Corp. will be issued upon the surrender of Certificates for exchange, no dividend or distribution on Middlefield Banc Corp. common stock will be payable on or for fractional share interests, and fractional share interests will not entitle the owner thereof to vote or to any other shareholder rights. In lieu of issuance of fractional shares, to each former holder of Liberty Bank common stock who otherwise would be

A-11

##### Table of Contents

entitled to receive a fractional share of Middlefield Banc Corp. common stock, Middlefield Banc Corp. will pay an amount in cash equal to the product of (x) the fraction of a share to which the holder would otherwise have been entitled and (y) the volume-weighted average closing price of a share of Middlefield Banc Corp. common stock for the 30 trading days immediately before the Closing Date, rounded to the nearest cent and without interest. For purposes of determining a fractional share interest, all shares of Liberty Bank common stock owned by a Liberty Bank stockholder will be combined for calculation of the maximum number of whole shares of Middlefield Banc Corp. common stock issuable to the Liberty Bank stockholder.

3.1.8 If Middlefield Banc Corp. changes, or if the Middlefield Banc Corp. Board sets a record date that will occur before the Effective Time for a change in, the number or kind of shares of Middlefield Banc Corp. common stock outstanding by a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction involving issuance of shares without consideration, the Merger Consideration will be adjusted proportionately to account for the change. If Liberty Bank changes, or if the Liberty Bank Board sets a record date that will occur before the Effective Time for a change in, the number or kind of shares of Liberty Bank common stock (or rights thereto) outstanding by a stock split, stock dividend, recapitalization, reclassification, reorganization, or similar transaction involving issuance of shares without consideration, the Merger Consideration will be adjusted proportionately to account for the change.

3.2 Election Procedures.

3.2.1 In accordance with the following procedures, holders of Liberty Bank common stock may elect to receive Stock Consideration or Cash Consideration (in either case without interest) in exchange for their shares of Liberty Bank common stock; provided, however, that, excluding Treasury Stock and Dissenting Shares, in the aggregate 45% of the total number of shares of Liberty Bank common stock issued and outstanding at the Effective Time are converted into the Stock Consideration (the “Stock Conversion Number”) and the remaining outstanding shares of Liberty Bank common stock are converted into the Cash Consideration. Shares of Liberty Bank common stock for which a Cash Election is made (including a Mixed Election, as defined in Section 3.2.2) are referred to herein as the “Cash Election Shares.” Shares of Liberty Bank common stock for which a Stock Election is made (including a Mixed Election) are referred to as the “Stock Election Shares.” Shares of Liberty Bank common stock for which no election is made or for which an Election Form is not returned properly completed are referred to herein as “Non-Election Shares.” The aggregate number of shares of Liberty Bank common stock for which a Stock Election is made is referred to herein as the “Stock Election Number.”

3.2.2 At least 20 business days before the anticipated Effective Time or on such other date as Middlefield Banc Corp. and Liberty Bank mutually agree (the “Mailing Date”) Middlefield Banc Corp. will mail or cause to be mailed to each holder of record of Liberty Bank common stock as of five business days before the Mailing Date (the “Election Form Record Date”) an election form and other appropriate and customary transmittal materials in such form as the parties shall mutually agree (the “Election Form”), specifying that, except with respect to shares of Liberty Common Stock held in book-entry form, delivery is effected and risk of loss and title to the Certificates passes only upon proper delivery of Certificates to the Exchange Agent. Subject to the allocation and election procedures set forth in this Section 3.2, the Election Form will permit each holder (1) to elect to receive Cash Consideration for all of the holder’s shares of Liberty Bank common stock (a “Cash Election”), (2) to elect to receive Stock Consideration for all of the shares (a “Stock Election”), (3) to receive Stock Consideration for part of the holder’s Liberty Bank common stock and Cash Consideration for the remaining part of the holder’s Liberty Bank common stock (a “Mixed Election”), or (4) to state no preference for receipt of cash or Middlefield Banc Corp. common stock (a “Non-Election”). A holder who holds shares of Liberty Bank common stock as nominee, trustee, or in another representative capacity may submit multiple Election Forms, provided that each Election Form covers all shares of Liberty Bank common stock held by the representative for a particular beneficial owner. Any shares of Liberty Bank common stock for which the holder does not by the Election Deadline make an effective election will be deemed Non-Election Shares.

3.2.3 To be effective, a properly completed Election Form must be submitted to the Exchange Agent on or before 5:00 p.m., New York City time, on the 20th day after the Mailing Date or such other time and date before

A-12

##### Table of Contents

the Effective Time as Middlefield Banc Corp. and Liberty Bank mutually agree (the “Election Deadline.” The Election Deadline may not be on or after the Effective Time. Liberty Bank will make available up to two separate Election Forms, or such additional Election Forms as Middlefield Banc Corp. may permit, to all persons who become holders or beneficial owners of Liberty Bank common stock between the Election Form Record Date and the close of business on the business day before the Election Deadline. Liberty Bank will provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein. An election is properly made if and only if the Exchange Agent actually receives a properly completed Election Form by the Election Deadline. If a holder of Liberty Bank common stock either (x) does not submit a properly completed Election Form in a timely fashion or (y) revokes the Election Form before the Election Deadline, the shares of Liberty Bank common stock held by that stockholder will be designated as Non-Election Shares. By written notice to the Exchange Agent, an Election Form may be revoked or changed by the person submitting the Election Form only if the notice of revocation or change is actually received by the Exchange Agent on or before the Election Deadline. Middlefield Banc Corp. will cause the Certificate or Certificates relating to a revoked Election Form to be promptly returned without charge to the person submitting the Election Form to the Exchange Agent. Subject to the terms of this Agreement and the terms of the Election Form, the Exchange Agent is entitled to determine when an election, modification, or revocation is received and whether an election, modification, or revocation is properly made.

3.2.4 If the Stock Election Number exceeds the Stock Conversion Number, all Cash Election Shares and all Non-Election Shares will be converted into the right to receive Cash Consideration, and subject to Section 3.1.7 hereof, each holder of Stock Election Shares will be entitled to receive the Stock Consideration solely for a number of Stock Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Stock Election Shares held by the holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of the holder’s Stock Election Shares being converted into the right to receive Cash Consideration.

3.2.5 If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), all Stock Election Shares will be converted into the right to receive Stock Consideration and the Non-Election Shares and Cash Election Shares will be treated in the following manner:

(A) if the Shortfall Number is less than or equal to the number of Non-Election Shares, all Cash Election Shares will be converted into the right to receive Cash Consideration and, subject to Section 3.1.7 hereof, each holder of Non-Election Shares will receive the Stock Consideration for a number of Non-Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Non-Election Shares held by the holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of the holder’s Non-Election Shares being converted into the right to receive Cash Consideration, or

(B) if the Shortfall Number exceeds the number of Non-Election Shares, all Non- Election Shares will be converted into the right to receive Stock Consideration, and subject to Section 3.1.7 each holder of Cash Election Shares will receive Stock Consideration for a number of Cash Election Shares held by that holder equal to the product obtained by multiplying (x) the number of Cash Election Shares held by the holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of the holder’s Cash Election Shares being converted into the right to receive Cash Consideration.

3.3 Procedures for Exchange of Liberty Bank Common Stock.

3.3.1 Middlefield Banc Corp. to Make Merger Consideration Available.

##### Table of Contents

sufficient to pay the Merger Consideration under this Article 3. Middlefield Banc Corp. will instruct the Exchange Agent to issue the cash and shares of Middlefield Banc Corp. common stock for exchange in accordance with this Section 3.3. Together with dividends or distributions payable but without interest thereon, the cash and shares of Middlefield Banc Corp. common stock deposited as provided herein are referred to as the “Exchange Fund.” The Exchange Fund also includes the cash to be deposited by Middlefield Banc Corp. under Section 3.5 for payment to holders of stock options and phantom shares.

3.3.2 Exchange of Certificates. Within five Business Days after the Effective Time Middlefield Banc Corp. will cause the Exchange Agent to mail to each holder of a Certificate or Certificates a form letter of transmittal for return to the Exchange Agent and instructions for surrendering the Certificates. The letter of transmittal will specify that delivery is effected and risk of loss and title to the Certificates pass only upon delivery of the Certificates (or in the case of Liberty Common Stock held in book-entry form, book-entry account statements), to the Exchange Agent. Upon proper surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with a properly completed and duly executed letter of transmittal, the holder of the Certificate is entitled to receive in exchange for the Merger Consideration. No interest will be paid or accrued on any cash payable in lieu of fractional shares or any unpaid dividends and distributions, if any, payable to holders of Certificates.

3.3.3 Rights of Certificate Holders after the Effective Time. After the Effective Time, the holder of a Certificate formerly representing issued and outstanding Liberty Bank common stock has no rights except the right to surrender the Certificate in exchange for Merger Consideration as provided in this Agreement. No dividends or other distributions declared after the Effective Time on Middlefield Banc Corp. common stock will be paid to the holder of any unsurrendered Certificate until the holder surrenders the Certificate in accordance with this Section 3.3. After surrender of a Certificate in accordance with this Section 3.3 the record holder is entitled to receive dividends or other distributions, without interest, which had become payable on shares of Middlefield Banc Corp. common stock.

3.3.4 Surrender by Persons Other than Record Holders. If the Person surrendering a Certificate and signing the accompanying letter of transmittal is not the record holder, it is a condition of the payment of the Merger Consideration that (x) the Certificate is properly endorsed to that Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on the Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering the Certificate and signing the letter of transmittal to do so on behalf of the record holder, and (y) the Person requesting exchange pays to the Exchange Agent in advance any transfer or other similar taxes required for payment to a Person other than the registered holder of the Certificate surrendered, or required for any other reason, or establishes to the Exchange Agent’s satisfaction that the tax has been paid or is not payable.

3.3.5 Closing of Transfer Books. From and after the Effective Time, there may be no transfers on the stock transfer books of Liberty Bank of the Liberty Bank common stock that were outstanding immediately before the Effective Time. If after the Effective Time Certificates representing shares are presented for transfer to the Exchange Agent, they will be exchanged for the Merger Consideration and canceled as provided in this Section 3.3.

3.3.6 Return of Exchange Fund. At any time after nine months have elapsed since the Effective Time, Middlefield Banc Corp. is entitled to require the Exchange Agent to deliver to Middlefield Banc Corp. any portion of the Exchange Fund made available to the Exchange Agent but not disbursed to holders of Certificates (including without limitation all interest and other income received by the Exchange Agent on funds made available to it), and thereafter holders are entitled to look solely to Middlefield Banc Corp. for any Merger Consideration that may be payable upon due surrender of Certificates (subject to abandoned property, escheat and other similar laws). However, neither Middlefield Banc Corp. nor the Exchange Agent is liable to any holder of a Certificate for any Merger Consideration delivered in good faith to a public official under abandoned property, escheat, or other similar law.

3.3.7 Lost, Stolen, or Destroyed Certificates. If a Person claiming a Certificate to be lost, stolen, or destroyed submits to the Exchange Agent an affidavit that the Certificate is lost, stolen, or destroyed and posts a bond in such amount as the Exchange Agent reasonably directs as indemnity against any claim that may be made against it for the Certificate, the Exchange Agent will issue the Merger Consideration in exchange for the lost, stolen, or destroyed Certificate.

3.3.8 Withholding. Middlefield Banc Corp. or the Exchange Agent is entitled to deduct and withhold from the consideration otherwise payable under this Agreement to any holder of Liberty Bank common stock such amounts as Middlefield Banc Corp. or the Exchange Agent is required to deduct and withhold under the Internal Revenue Code of 1986 or under any other applicable provision of U.S. federal, state, local, or non-U.S. tax law. If properly withheld by Middlefield Banc Corp. or the Exchange Agent, the withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the Liberty Bank common stock.

3.4 Reservation of Shares. Middlefield Banc Corp. will reserve for issuance a sufficient number of shares of Middlefield Banc Corp. common stock for issuing the Stock Consideration to Liberty Bank stockholders in accordance with this Article 3.

3.5 Termination of Options and Phantom Stock. At the Effective Time all outstanding options, phantom stock rights, or other rights to acquire Liberty Bank common stock, whether vested or not vested, will be cancelled and will instead represent solely the right to receive in cash from Middlefield Banc Corp. the difference between $41.09 per share and, if less, the exercise or strike price of the option or right. The number and terms of options and rights will not exceed or differ from the number and terms disclosed in Liberty Bank Disclosure Schedule 4.2.1. If the exercise or strike price of an option or right equals or exceeds $41.09, the option or right will be cancelled without any payment in exchange.

4.5 Financial Statements.

4.5.1 The Liberty Bank Regulatory Reports filed with the OCC were prepared in all material respects in accordance with applicable regulatory accounting principles and practices throughout the periods covered by the reports.

4.5.2 Liberty Bank made available to Middlefield Banc Corp. the Liberty Bank Financial Statements for the periods through June 30, 2016. The Liberty Bank Financial Statements fairly present in each case in all material respects (subject in the case of unaudited interim statements to normal year-end adjustments) the financial position, results of operations, and cash flows of Liberty Bank and the Liberty Bank Subsidiaries as of and for the respective periods ending on the dates thereof, in accordance with GAAP during the periods involved, except as stated in the notes thereto, or in the case of unaudited statements as permitted by GAAP.

4.5.3 At the date of the most recent balance sheet included in the Liberty Bank Financial Statements or Liberty Bank Regulatory Reports Liberty Bank did not have any liabilities, obligations, or loss contingencies of any nature (whether absolute, accrued, contingent, or otherwise) of a type required to be presented in the Liberty Bank Financial Statements or Liberty Bank Regulatory Reports or in footnotes that are not fully presented or reserved against therein or fully disclosed in a footnote, except for liabilities, obligations, and loss contingencies that are not material individually or in the aggregate or that were incurred in the ordinary course of business consistent with past practice, and subject in the case of any unaudited statements to normal, recurring audit adjustments and absence of footnotes.

Liberty Bank and the Liberty Bank Subsidiaries are subject to Tax audits in the ordinary course of business. Liberty Bank management does not believe that an adverse resolution of Tax audits of which it has Knowledge would be reasonably likely to have a Material Adverse Effect on Liberty Bank. Liberty Bank and the Liberty Bank Subsidiaries have not been notified in writing by any jurisdiction that Liberty Bank or any Liberty Bank Subsidiary is required to file in the jurisdiction a Tax Return that has not been filed. Neither Liberty Bank nor any Liberty Bank Subsidiary is a member of a group that has filed or been included in a combined, consolidated, or unitary income Tax Return other than a group the common

7.10.1 Middlefield Banc Corp. and The Middlefield Banking Company shall endeavor to retain as many of the current officers and employees of Liberty Bank as is commercially reasonable and possible in light of its banking template and post-Mergers business plans. It is understood and agreed that nothing in this Section 7.10.1 or elsewhere in this Agreement shall be deemed to be a contract of employment or be construed to give said employees any rights other than as employees at will under Ohio law and said employees shall not be deemed to be third-party beneficiaries of this provision. Liberty Bank employees who become employees of Middlefield Banc Corp. or The Middlefield Banking Company after the Effective Time (“Continuing Employees”) will be eligible to participate in any Middlefield Benefit Plan of similar character available to other employees of Middlefield Banc Corp. or The Middlefield Banking Company (other than any nonqualified deferred compensation plan or agreement, employment agreement, or change in control agreement). Solely for purposes of determining eligibility for and any applicable vesting period (and not for benefit accrual purposes), Continuing Employees who become participants in a Middlefield Benefit Plan will receive credit for eligibility and vesting requirements for service as Liberty Bank employees before the Effective Time. This Agreement does not restrict the ability of Middlefield Banc Corp. or The Middlefield Banking Company from and after the Effective Time to terminate employment of any Liberty Bank employee. Except for contractual commitments, if any, specifically made or assumed by Middlefield Banc Corp. under this Agreement or by operation of law, neither Middlefield Banc Corp. nor any Middlefield Subsidiary is obliged after the Effective Time to continue the employment or particular job responsibilities or specified level of compensation, benefits, or perquisites of any Person employed by Liberty Bank at the Effective Time.

If a payment would constitute a parachute payment, the payment will be reduced to one dollar less than the amount beyond which the payment would be considered a parachute payment.

A-49

agreement identified in Liberty Bank Disclosure Schedule 4.12.1, the Liberty Bank executive identified in Liberty Bank Disclosure Schedule 4.12.1 must agree to comply with the noncompete and nonsolicitation restrictions on terms comparable to the noncompete and nonsolicitation restrictions stated in the agreement identified in Liberty Bank Disclosure Schedule 4.12.1.

As a condition to entitlement to severance pay, Employees must execute appropriate release of claims documents. For purposes of this provision, cause means termination because of material neglect of or material refusal to perform any duty or responsibility as an employee other than as a result of sickness, accident, or similar cause beyond an employee’s reasonable control, dishonesty, commission of a crime (other than minor traffic violations), or misconduct. Severance under this Section 7.10.3 is one (1) week of base pay for each full year of service (including service with Liberty Bank, Middlefield Banc Corp., or a subsidiary of either), with a minimum of 4 weeks and a maximum of 26 weeks of base pay. For purposes of this provision, base pay means base salary before pre-tax deductions for a salaried employee, and for an hourly employee the employee’s total scheduled hours (prorated, as appropriate) before any pre- tax deductions for the 12 full calendar months preceding the month in which the Effective Time occurs. In addition to severance under this Section 7.10.3, Middlefield Banc Corp. may pay retention or other incentive bonuses to Liberty Bank employees identified by Middlefield Banc Corp. after consulting with Liberty Bank, as critical to data processing or other transition tasks or who are otherwise determined by Middlefield Banc Corp. to be key officers or employees. Retention bonuses may have a vesting term of up to two years, with bonus forfeiture occurring for termination before vesting. Retention bonuses, if any, would be in addition to any bonus for which any former Liberty Bank officer or employee may be eligible as an employee of Middlefield Banc Corp. or The Middlefield Banking Company.

7.10.4 Middlefield Banc Corp. will make available to any Person who is an employee of Liberty Bank at the Effective Time but whose employment does not continue with Middlefield Banc Corp. or The Middlefield Banking Company after the Effective Time or whose employment is terminated within one year after the Effective Time, (excluding any employee terminated for cause), career placement counseling and professional counseling services through Middlefield Banc Corp.’s employee assistance program.

7.10.5 Positions (other than for those executive officers named in Middlefield Banc Corp.’s latest proxy statement and those officers designated as Regulation O officers), which become open with Middlefield Banc Corp., The Middlefield Banking Company or any of the Middlefield Subsidiaries in the ordinary course of business will be communicated to Liberty Bank’s Chief Financial Officer, Richard Ebner, after the date of this Agreement, and Liberty Bank employees will be given an opportunity to apply for such positions.

7.11 Board. Middlefield Banc Corp. will take all necessary action to fulfill its obligation under Section 2.5.3 to appoint Messrs. Valerian and Bevan to serve as directors of Middlefield Banc Corp. immediately after the Effective Time. If, prior to the Effective Time, either Messrs. Valerian and/or Bevan is unable to serve, Liberty Bank will designate a mutually agreed upon successor(s) for appointment to Middlefield Banc Corp.’s Board of Directors. Middlefield Banc Corp. also will maintain after the Effective Time a Northeast Ohio Advisory Board. Prior to the Effective Time, Middlefield Banc Corp. will consult with the Liberty Bank Board of Directors about the composition of the Northeast Ohio Advisory Board.

7.12 Director, Officer and Employee Indemnification and Director and Officer Insurance.

7.12.1 For six years after the Effective Time, Middlefield Banc Corp. will maintain directors’ and officers’ liability insurance for actions, omissions, or events occurring before the Effective Time, covering persons who on the date of this Agreement are covered by Liberty Bank’s current directors’ and officers’ liability insurance

policy. The coverage will be on terms substantially equivalent to the terms of Liberty Bank’s coverage on the date of this Agreement; provided, however, Middlefield Banc Corp. is not required to expend annually under this Section 7.12.1 an amount exceeding 150% of Liberty Bank’s cost for directors’ and officers’ liability insurance coverage on the date of this Agreement as set forth on Liberty Bank Disclosure Schedule 7.12.1 (the “Maximum Amount”). If the cost of coverage exceeds the Maximum Amount, Middlefield Banc Corp. will instead maintain the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to the Maximum Amount. Instead of the directors’ and officers’ liability insurance coverage outlined in this Section 7.12.1, Middlefield Banc Corp., or Liberty Bank with the consent of Middlefield Banc Corp., which consent will not be unreasonably withheld, may obtain at or before the Effective Time a prepaid tail policy providing single-limit equivalent coverage to that described in this Section 7.12.1 for a per annum premium cost not to exceed 150% of the annual premium most recently paid by Liberty Bank. Written evidence of the directors’ and officers’ liability insurance coverage secured pursuant to this Section 7.12.1 will be provided to the Liberty Bank directors and officers at Closing. So that Middlefield Banc Corp. may fulfill its agreement to provide directors’ and officers’ liability insurance policies for six years, Liberty Bank agrees to provide the insurer or substitute insurer with such representations as the insurer may reasonably request for reporting of prior claims.

7.12.2 In addition to Section 7.12.1, Middlefield Banc Corp. will for six years after the Effective Time and to the fullest extent permitted under applicable law and Liberty Bank’s articles of association and bylaws indemnify, defend, and hold harmless each Person who is on the date of this Agreement, who has been at any time before the date hereof, or who before the Effective Time becomes an officer, director or employee of Liberty Bank, or a Liberty Bank Subsidiary (“Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorneys’ fees), liabilities, judgments, or amounts that are paid in settlement (provided settlement occurred with the advance written consent of Middlefield Banc Corp., not unreasonably withheld, conditioned, or delayed) of or for any claim, action, suit, proceeding, or investigation, whether civil, criminal, or administrative (“Claim”) in which an Indemnified Party is or is threatened to be made a party or witness in whole or in part or arising in whole or in part on account of the Person being or having been an officer or director of Liberty Bank or serving or having before the Effective Time at the request of any such party as a director, officer, employee, trustee, or partner of another Person or benefit plan if the Claim pertains to any matter of fact arising, existing, or occurring before the Effective Time (including without limitation the Mergers and the other transactions under this Agreement), regardless of whether the Claim is asserted or claimed before or after the Effective Time. An Indemnified Party wishing to claim indemnification under this Section 7.12.2 must upon learning of the notify Middlefield Banc Corp., but failure to notify Middlefield Banc Corp. does not relieve Middlefield Banc Corp. from liability it may have under this Section 7.12.2 unless failure to notify Middlefield Banc Corp. materially prejudices Middlefield Banc Corp. If a Claim is made before or after the Effective Time Middlefield Banc Corp. may assume the defense (and the Indemnified Parties will cooperate in the defense), and Middlefield Banc Corp. is not liable to any Indemnified Party for legal expenses of other counsel or other expenses subsequently incurred by any Indemnified Party. If Middlefield Banc Corp. elects not to assume the defense, or if counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are or may be (regardless of whether any have yet actually arisen) issues raising conflicts of interest between Middlefield Banc Corp. and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Middlefield Banc Corp. is responsible for paying reasonable fees and expenses of counsel for the Indemnified Parties. Middlefield Banc Corp. is obligated for no more than one counsel for all Indemnified Parties unless there is a conflict of interest requiring more than one counsel. Middlefield Banc Corp. is not liable for any settlement effected without its advance written, which consent may not be unreasonably withheld, conditioned, or delayed. Middlefield Banc Corp. will advance expenses as incurred in each case upon receipt of an undertaking from the Indemnified Party to repay advanced expenses if it is determined by a final and nonappealable judgment of a court of competent jurisdiction that the Indemnified Party is not entitled to indemnification.

7.12.3 If either Middlefield Banc Corp. or a successor or assign of Middlefield Banc Corp. consolidates with or merges into another Person and is not the continuing or surviving company or entity or transfers all or substantially all of its properties and assets to a Person, proper provision will be made so that the surviving company or entity or transferee assumes the obligations of

Middlefield Banc Corp. shall take all steps as may be necessary or appropriate to cause the transactions contemplated by Article 3 and any other acquisitions of equity securities of Middlefield Banc Corp. in connection with the consummation of the transactions contemplated by this Agreement to be exempt under Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended.

This Agreement, including the Exhibits and Disclosure Schedules and the documents and other writings referred to herein or delivered under this Agreement, the March 21, 2016 Confidentiality Agreement of Middlefield Banc Corp., and the Voting Agreements contain the entire agreement and understanding of the parties concerning the subject matter. There are no restrictions, agreements, promises, warranties, covenants, or undertakings between the parties other than those expressly set forth herein or therein.

11.6 Counterparts. This Agreement may be executed in one or more counterparts, all of which together will be considered one and the same agreement and each of which will be considered an original. A facsimile copy of a signature page is considered an original signature page.

11.7 Severability. If any provision of this Agreement is held invalid, illegal, or unenforceable by a court of competent jurisdiction, invalidity, illegality, or unenforceability does not affect any other provisions of this Agreement. The parties will use reasonable efforts to substitute a valid, legal, and enforceable provision implementing as far as possible the purpose and intent the affected provision of this Agreement.

11.8 Governing Law. This Agreement is governed by and will be construed in accordance with the laws of the State of Ohio, without giving effect to principles of conflicts of law.

11.9 Interpretation. When a reference is made in this Agreement to Articles, Sections or Exhibits, the reference is to an Article or Section of or Exhibit to this Agreement unless otherwise indicated. The recitals in this Agreement are an integral part of this Agreement. References to sections include subsections, which are part of the related Section (e.g., a section numbered “Section 5.5.1” is part of “Section 5.5” and references to “Section 5.5” also refer to material contained in the subsection described as “Section 5.5.1”). The table of contents and headings contained in this Agreement are for reference purposes only and do not affect the meaning or interpretation of this Agreement. Whenever the words “include,” “includes,” or “including” are used in this Agreement, they are deemed to be followed by the words “without limitation.” Unless the context otherwise requires, the phrases “the date of this Agreement,” “the date hereof,” and terms of similar import refer to the date in the Preamble to this Agreement. When this Agreement recites that a party will take a specified action, it means the party is required by this Agreement to take the specified action. The parties have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party based on authorship of any of the provisions of this Agreement.

11.10 Specific Performance. The parties hereto agree that irreparable damage will occur if the provisions contained in this Agreement are not performed in accordance with their specific terms or are otherwise breached. It is therefore agreed that the parties are entitled to an injunction or injunctions, without posting bond or other security, to prevent breaches of this Agreement and to enforce specifically the terms and provisions in any court of the United States or any state having jurisdiction, except where another remedy is expressly provided by this Agreement. Each party agrees that it will not seek and will agree to waive any requirement for securing or posting bond in the other party’s seeking or obtaining such relief.

11.11 Waiver of Trial by Jury. The parties hereto hereby knowingly, voluntarily and intentionally waive the right any may have to a trial by jury in any litigation based on or rising out of or under this Agreement and any agreement to be executed in accordance with this Agreement, or any course of conduct, course of dealing, statements (whether verbal or written) or actions of either party.

11.12 Amendment and Waiver. (a) Whether before or after Liberty Bank Stockholder Approval or Middlefield Shareholder Approval is obtained, by action of the Board of Directors of each of Liberty Bank, Middlefield Banc Corp., and The Middlefield Banking Company, this Agreement may be amended by an instrument in writing signed by Liberty Bank, Middlefield Banc Corp., and The Middlefield Banking Company.

##### Table of Contents

However, after approval of this Agreement and the Mergers by Liberty Bank stockholders, without further Liberty Bank Stockholder Approval an amendment of this Agreement is not effective if the amendment decreases the amount or value of Merger Consideration or changes the form of Merger Consideration.

(b) By action of its Board of Directors, Liberty Bank may (x) waive compliance with any of the agreements or conditions of Middlefield Banc Corp. and The Middlefield Banking Company, (y) waive any inaccuracies in the representations and warranties of Middlefield Banc Corp. and The Middlefield Banking Company, or (z) extend the time for performance of the obligations of Middlefield Banc Corp. and The Middlefield Banking Company.

An extension or waiver by a party is effective if and only if the extension or waiver is in writing and is signed by the party. A party’s failure to insist on strict compliance with an obligation, covenant, agreement, or condition is not a waiver of subsequent noncompliance.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement by their duly authorized officers as of the date first written above.

Exhibit A

July 28, 2016

Middlefield Banc Corp.

15985 East High Street

Middlefield, Ohio 44062-0035

Ladies and Gentlemen:

Concurrently with the execution of this letter agreement (“Voting Agreement”), Middlefield Banc Corp., The Middlefield Banking Company, and Liberty Bank, N.A. (“Liberty Bank”), are entering into an Agreement and Plan of Reorganization dated the date of this Voting Agreement (the “Merger Agreement”), whereby Liberty Bank will merge into The Middlefield Banking Company (the “Merger”) and stockholders of Liberty Bank will receive cash and shares of Middlefield Banc Corp. common stock on terms stated in the Merger Agreement, subject to closing of the Merger. All defined terms used but not defined in this Voting Agreement have the meanings given in the Merger Agreement.

A condition to Middlefield Banc Corp.’s obligations under the Merger Agreement is that I execute and deliver this Voting Agreement to Middlefield Banc Corp.

Intending to be legally bound, I irrevocably agree and represent as follows:

(a) As of the date of this Voting Agreement I have, and at all times during the term of this Voting Agreement I will have, beneficial ownership of, and good and valid title to, shares of Liberty Bank common stock, par value $10.00 per share. I hold options or rights to acquire shares of Liberty Bank common stock. All of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock are owned free and clear of any proxy or voting restriction, claims, liens, encumbrances, and security interests and any other limitation or restriction whatsoever (including any restriction on the right to dispose of the securities). None of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock are subject to a voting trust or other agreement or arrangement regarding voting rights of the securities. For purposes of this Voting Agreement beneficial ownership is defined in Rule 13d-3 under the Securities Exchange Act of 1934.

(b) Except for the shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock stated in paragraph (a), as of the date of this Voting Agreement I do not beneficially own any (x) shares of capital stock or voting securities of Liberty Bank, (y) securities of Liberty Bank convertible into or exchangeable for shares of capital stock or voting securities of Liberty Bank or (z) options or other rights to acquire from Liberty Bank any capital stock, voting securities, or securities convertible into or exchangeable for capital stock or voting securities of Liberty Bank. The shares of Liberty Bank common stock identified in paragraph (a), together with all shares of Liberty Bank common stock I acquire during the term of this Voting Agreement, including through exercise of options or rights, are subject to the terms of this Voting Agreement.

(c) At the Liberty Bank Stockholder Meeting at which the Merger Agreement and the Merger will be voted upon, and on every action or approval by written consent of stock of Liberty Bank, I will vote or cause to be voted all shares over which I have voting power to be voted in favor of approval and adoption of the Merger Agreement, the Merger, and other transactions under the Merger Agreement and in favor of any proposal to adjourn or postpone the meeting to a later date if there are not sufficient votes to approve the Merger Agreement, the Merger, and other transactions under the Merger Agreement.

(d) During the term of this Voting Agreement I will not offer, sell, transfer, pledge, encumber, or otherwise dispose of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock (or interest therein), and I will use my best efforts to not permit the offer, sale, transfer, pledge, encumbrance, or other disposition of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, except as may be permitted by paragraph (g).

A-63

##### Table of Contents

(e) I agree that Liberty Bank is not bound by any attempted sale of any of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, and Liberty Bank’s transfer agent will receive appropriate stop transfer orders and is not required to register any such attempted sale of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock, unless the sale is effected in compliance with this Voting Agreement.

(f) I have the legal capacity to enter into this Voting Agreement. I have duly and validly executed and delivered this Voting Agreement. This Voting Agreement is a valid and binding obligation enforceable against me in accordance with its terms, subject to bankruptcy, insolvency, and other laws affecting creditors’ rights and general equitable principles. No consent of my spouse, (if any), is necessary under any community property or other law in order for me to enter into and perform my obligations under this Voting Agreement.

(g) I may offer, sell, transfer, pledge, encumber, or otherwise dispose of my shares of Liberty Bank common stock or options or rights to acquire Liberty Bank common stock to my spouse, children, or grandchildren, but to do so I must first cause the person to whom I transfer the securities to execute and deliver to Middlefield Banc Corp. an agreement to be bound by the terms of this Voting Agreement. A transfer not preceded by the transferee’s executed Voting Agreement delivered to Middlefield Banc Corp. is not valid or effective and will not be honored.

I am signing this Voting Agreement solely in my capacity as a stockholder of Liberty Bank, and as an option holder if I hold options or rights to acquire Liberty Bank common stock. I am not signing this Voting Agreement in any other capacity, such as a director or officer of Liberty Bank or as a fiduciary of any trusts in which I am not a beneficiary. I make no agreement in this Voting Agreement in any capacity other than in my capacity as a beneficial owner of Liberty Bank common stock. Nothing in this Voting Agreement limits or affects any action or inaction by me or any of my representatives, as applicable, as a director or officer of Liberty Bank or affects my rights to exercise my fiduciary duties pursuant to Section 8.2(b) of the Merger Agreement.

This Voting Agreement terminates and is of no further force and effect on the earliest to occur of (a) the favorable vote of Liberty Bank stockholders for approval and adoption of the Merger Agreement and the Merger, (b) the Effective Time, (c) Middlefield Banc Corp. and I enter into a written agreement to terminate this Voting Agreement, or (d) any termination of the Merger Agreement in accordance with its terms, except that termination is without prejudice to Middlefield Banc Corp.’s rights if termination is a result of my willful breach of any covenant or representation in this Voting Agreement.

All notices and other communications under this Voting Agreement must be in writing and will be deemed given if delivered personally, sent by facsimile, mailed by registered or certified mail return receipt requested, or delivered by an express courier, to the other party at its addresses contained on the signature page.

This Voting Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties. This Voting Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, between the parties concerning the subject matter of this Voting Agreement.

I agree and acknowledge that Middlefield Banc Corp. may be irreparably harmed by, and that there is no adequate remedy at law for, a violation of this Voting Agreement by me. Without limiting other remedies, Middlefield Banc Corp. is entitled to enforce this Voting Agreement by specific performance or injunctive relief. This Voting Agreement and all claims arising hereunder or relating hereto are governed by and will be construed and enforced in accordance with the laws of the State of Ohio, without giving effect to the State of Ohio principles of conflicts of law. I hereby irrevocably and unconditionally submit to the exclusive jurisdiction of any Ohio state court or the United States District Court for the Northern District of Ohio in any action or proceeding arising out of or relating to this Voting Agreement.

If a term, provision, covenant, or restriction of this Voting Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void, or unenforceable, the remainder of the terms, provisions, covenants, and restrictions of this Voting Agreement remain in full force and effect and are not affected, impaired, or invalidated so long as the effect on the economic or legal substance is not materially adverse to a party. If a term, provision, covenant, or restriction of this Voting Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void, or unenforceable, the parties will negotiate in good faith to modify this Voting Agreement to effect the original intent of the parties as closely as possible.

This Voting Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed is deemed to be an original but all of which taken together constitute a single instrument.

Very truly yours,

ANNEX B

DISSENTERS’ RIGHTS UNDER 12 U.S.C. §215(b) – (d)

(b) Liability of consolidated association; capital stock; dissenting shareholders

The consolidated association shall be liable for all liabilities of the respective consolidating banks or associations. The capital stock of such consolidated association shall not be less than that required under existing law for the organization of a national bank in the place in which it is located: Provided, That if such consolidation shall be voted for at such meetings by the necessary majorities of the shareholders of each association and State bank proposing to consolidate, and thereafter the consolidation shall be approved by the Comptroller, any shareholder of any of the associations or State banks so consolidated who has voted against such consolidation at the meeting of the association or bank of which he is a stockholder, or who has given notice in writing at or prior to such meeting to the presiding officer that he dissents from the plan of consolidation, shall be entitled to receive the value of the shares so held by him when such consolidation is approved by the Comptroller upon written request made to the consolidated association at any time before thirty days after the date of consummation of the consolidation, accompanied by the surrender of his stock certificates.

(c) Valuation of shares

The value of the shares of any dissenting shareholder shall be ascertained, as of the effective date of the consolidation, by an appraisal made by a committee of three persons, composed of (1) one selected by the vote of the holders of the majority of the stock, the owners of which are entitled to payment in cash; (2) one selected by the directors of the consolidated banking association; and (3) one selected by the two so selected. The valuation agreed upon by any two of the three appraisers shall govern. If the value so fixed shall not be satisfactory to any dissenting shareholder who has requested payment, that shareholder may, within five days after being notified of the appraised value of his shares, appeal to the Comptroller, who shall cause a reappraisal to be made which shall be final and binding as to the value of the shares of the appellant.

(d) Appraisal by Comptroller; expenses of consolidated association; sale and resale of shares; State appraisal and consolidation law

If, within ninety days from the date of consummation of the consolidation, for any reason one or more of the appraisers is not selected as herein provided, or the appraisers fail to determine the value of such shares, the Comptroller shall upon written request of any interested party cause an appraisal to be made which shall be final and binding on all parties. The expenses of the Comptroller in making the reappraisal or the appraisal, as the case may be, shall be paid by the consolidated banking association. The value of the shares ascertained shall be promptly paid to the dissenting shareholders by the consolidated banking association. Within thirty days after payment has been made to all dissenting shareholders as provided for in this section the shares of stock of the consolidated banking association which would have been delivered to such dissenting shareholders had they not requested payment shall be sold by the consolidated banking association at an advertised public auction, unless some other method of sale is approved by the Comptroller, and the consolidated banking association shall have the right to purchase any of such shares at such public auction, if it is the highest bidder therefor, for the purpose of reselling such shares within thirty days thereafter to such person or persons and at such price not less than par as its board of directors by resolution may determine. If the shares are sold at public auction at a price greater than the amount paid to the dissenting shareholders the excess in such sale price shall be paid to such shareholders. The appraisal of such shares of stock in any State bank shall be determined in the manner prescribed by the law of the State in such cases, rather than as provided in this section, if such provision is made in the State law; and no such consolidation shall be in contravention of the law of the State under which such bank is incorporated.

Board of Directors

Liberty Bank, National Association

Signature Square, Building One

25201 Chagrin Boulevard, Suite 120

Beachwood, OH 44122

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of shares of issued and outstanding common stock, $10.00 par value (the “Company Common Shares”), of Liberty Bank, National Association (“Liberty”) of the Merger Consideration (as defined below) to be received by such holders in the proposed merger (the “Proposed Merger”) of MBC Interim Bank., a wholly-owned subsidiary of Middlefield Banc Corp., with and into Liberty as set forth in the Agreement and Plan of Reorganization dated July 27, 2016 (the “Merger Agreement”). Middlefield Banc Corp. and MBC Interim Bank are referred to individually and collectively herein as “MBCN.” As detailed in the Merger Agreement, pursuant to the Proposed Merger, each Company Common Share issued and outstanding immediately prior to the effective time of the Proposed Merger will be converted, at the election of the holder thereof (subject to the cash/stock aggregate consideration provisions of the Merger Agreement), into the right to receive $37.96 in cash or 1.1934 shares of MBCN common stock, no par value, in addition to a cash special dividend of approximately $3.13 per share (the “Merger Consideration”).

In arriving at our opinion, we have, among other things: (i) reviewed the historical financial performance, current financial position and general prospects of each of MBCN and Liberty and reviewed certain internal financial analyses and forecasts prepared by the respective management teams of MBCN and Liberty, (ii) reviewed the Merger Agreement, (iii) reviewed and analyzed the stock performance and trading history of MBCN, (iv) studied and analyzed the consolidated financial and operating data of MBCN and Liberty, (v) reviewed the pro forma financial impact of the Proposed Merger on MBCN, based on assumptions relating to transaction expenses, purchase accounting adjustments, cost savings and other synergies determined by the respective management teams of MBCN and Liberty, (vi) considered the financial terms of the Proposed Merger as compared with the financial terms of comparable bank and bank holding company mergers and acquisitions, (vii) met and/or communicated with certain members of each of MBCN’s and Liberty’s senior management to discuss their respective operations, historical financial statements and future prospects, and (viii) conducted such other financial analyses, studies and investigations as we deemed appropriate.

Our opinion is given in reliance on information and representations made or given by MBCN, Liberty, and their respective officers, directors, auditors, counsel and other agents, and on filings, releases and other information issued by each of MBCN and Liberty, including financial statements and financial projections, stock price data, as well as certain other information from recognized independent sources. We have not independently verified the information or data concerning MBCN or Liberty nor any other data we considered in our review and, for purposes of the opinion set forth below, we have assumed and relied upon the accuracy and completeness of all

such information and data. We have assumed that all forecasts and projections provided to us have been reasonably prepared and reflect the best currently available estimates and good faith judgments of the respective management teams of MBCN and Liberty as to their most likely future financial performance. We express no opinion as to any financial projections or the assumptions on which they are based. We have not conducted any valuation or appraisal of any assets or liabilities of MBCN or Liberty, nor have any such valuations or appraisals been provided to us. Additionally, we assume that the Proposed Merger is, in all respects, lawful under applicable law.

With respect to anticipated transaction costs, purchase accounting adjustments, expected cost savings and other synergies and financial and other information relating to the general prospects of MBCN and Liberty, we have assumed that such information has been reasonably prepared and reflects the best currently available estimates and good faith judgment of the respective management teams of MBCN and Liberty as to their most likely future performance. We have further relied on the assurances of the respective management teams of MBCN and Liberty that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We have assumed that the allowance for loan losses indicated on the balance sheet of each of MBCN and Liberty is adequate to cover such losses; we have not reviewed loans or credit files of MBCN or Liberty. We have assumed that all of the representations and warranties contained in the Merger Agreement and all related agreements are true and correct, that each party under the agreements will perform all of the covenants required to be performed by such party under the agreements, and that the conditions precedent in the agreements will not be waived. Also, in rendering our opinion, we have assumed that in the course of obtaining the necessary regulatory approvals for the consummation of the Proposed Merger, no conditions will be imposed that will have a material adverse effect on the combined entity or contemplated benefits of the Proposed Merger, including the cost savings and related expenses expected to result from the Proposed Merger.

Our opinion is based upon information provided to us by the respective management teams of MBCN and Liberty, as well as market, economic, financial and other conditions as they exist and can be evaluated only as of the date hereof and accordingly, it speaks to no other period. We have not undertaken to reaffirm or revise this opinion or otherwise comment on events occurring after the date hereof and do not have an obligation to update, revise or reaffirm our opinion. Our opinion does not address the relative merits of the Proposed Merger or the other business strategies that Liberty’s Board of Directors has considered or may be considering, nor does it address the underlying business decision of Liberty’s Board of Directors to proceed with the Proposed Merger. We were not asked to and did not solicit or explore other strategic alternatives to the Proposed Merger. We are expressing no opinion as to the prices at which MBCN’s securities may trade at any time. Nothing in our opinion is to be construed as constituting tax advice or a recommendation to take any particular tax position, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that MBCN has obtained such advice as it deemed necessary from qualified professionals. Our opinion is for the information of Liberty’s Board of Directors in connection with its evaluation of the Proposed Merger and does not constitute a recommendation to the Board of Directors of Liberty in connection with the Proposed Merger or a recommendation to any shareholder of Liberty as to how such shareholder should vote or act with respect to the Proposed Merger. This opinion should not be construed as creating any fiduciary duty on Boenning & Scattergood, Inc.’s part to any party or person. Our opinion is not to be quoted or referred to, in whole or in part, in a registration statement, prospectus, proxy statement or in any other document, nor shall this opinion be used for any other purpose, without our prior written consent, except that, if required by applicable

law, this opinion may be referenced and included in its entirety in any filing made by MBCN in respect to the Proposed Merger with the Securities and Exchange Commission; provided, however, any description of or reference to our opinion or to Boenning & Scattergood, Inc. be in a form reasonably acceptable to us and our counsel. We shall have no responsibility for the form or content of any such disclosure, other than the opinion itself.

Boenning & Scattergood, Inc., as part of its investment banking business, regularly is engaged in the valuation of assets, securities and companies in connection with various types of transactions, including mergers, acquisitions, private placements, public offerings and valuations for various other purposes, and in the determination of adequate consideration in such transactions. In the ordinary course of our business as a broker-dealer, we may, from time to time, purchase securities from, and sell securities to, MBCN, Liberty, and/or their respective affiliates. In the ordinary course of business, we may also actively trade the securities of MBCN for our own account and/or for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

We are acting as Liberty’s financial advisor in connection with the Proposed Merger and will receive a fee for our services, a significant portion of which is contingent upon consummation of the Proposed Merger. We will also receive a fee for rendering this opinion. Our fee for rendering this opinion is not contingent upon any conclusion that we may reach or upon completion of the Proposed Merger. Liberty has also agreed to indemnify us against certain liabilities that may arise out of our engagement.

Boenning & Scattergood, Inc. was engaged in February 2016 by MBCN to serve as placement agent for a private placement of common stock. The offering ultimately closed on June 30, 2016, and Boenning & Scattergood, Inc. was paid a commission for its role. Boenning & Scattergood, Inc., advised, and received compensation from, Liberty in 2014 relating to the exploration of strategic alternatives, although no transaction was consummated at that time.

Except for the arrangements between Boenning & Scattergood, Inc. and Liberty described in the preceding paragraphs, Boenning & Scattergood, Inc. has not had any material relationship with Liberty during the past two years in which compensation was received or was intended to be received. Boenning & Scattergood, Inc. may provide services to MBCN in the future (and/or to Liberty if the Proposed Merger is not consummated), although as of the date of this opinion, there is no agreement to do so nor any mutual understanding that such services are contemplated.

This opinion has been approved by Boenning & Scattergood, Inc.’s fairness opinion committee. We do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Proposed Merger by any of the officers, directors, or employees of any party to the Merger Agreement, or any class of such persons, relative to the compensation to be received by the holders of Company Common Shares in the Proposed Merger.

Middlefield, Ohio 44062

Attention: Tom Caldwell – President and CEO

Members of the Board of Directors:

Middlefield Banc Corp., holding company of The Middlefield Banking Company (collectively “MBCN” or the “Company”), has agreed to enter into an agreement and plan of reorganization (the “Agreement”), with Liberty Bank, N.A. (“Liberty”), and MBC Interim Bank pursuant to which the issued and outstanding shares of the capital stock of Liberty (which total 959,283 as of the date of this letter) will be acquired by MBCN in a transaction (the “Acquisition”) for which MBCN will issue stock consideration to Liberty shareholders at a fixed exchange ratio of 1.1934x or cash consideration of $37.96 per share, subject to proration to ensure that, in the aggregate, 45% of Liberty’s shares of common stock outstanding are converted into MBCN’s common stock for each share of Liberty common stock issued and outstanding (the “Merger Consideration”) as defined in the Agreement. In addition, and immediately prior to closing of the Acquisition, Liberty will declare a special cash dividend (“Special Dividend”) to be paid to Liberty shareholders in the amount of $3,000,000, or approximately $3.13 per share. Pursuant to the Agreement and assuming an MBCN stock price of $31.81 per share, the total consideration (Merger Consideration plus Special Dividend, together “Total Consideration”) to Liberty shareholders amounts to $41.09 per share, or $39,415,269. Additionally, Liberty has 91,561 stock options and phantom stock outstanding with a weighted average strike price of approximately $28.56 that will be cashed out at closing. The value of the stock option and phantom stock consideration is calculated by taking the difference between the consideration per share price of $41.09 and the weighted average strike price of $28.56, multiplied by the 91,561 stock options and phantom stock equaling $1,147,357 in stock option and phantom stock consideration. When added to the Total Consideration of $39,415,269, the aggregate value of the transaction consideration (the “Transaction Consideration”) is $40,562,627, including stock options and phantom stock, or $42.28 per share.

You have asked us whether, in our opinion, the Transaction Consideration is fair to the shareholders of MBCN from a financial point of view.

Donnelly Penman & Partners Inc. (“Donnelly Penman”) is an investment banking firm of recognized standing. As part of our investment banking services, we are continually engaged in the valuation of businesses and securities in connection with mergers and acquisitions, secondary distributions of securities, private placements and valuations for going private transactions, corporate and other purposes.

On April 19, 2016, Donnelly Penman was engaged by MBCN through a letter agreement (the “Engagement Letter”) to provide merger advisory services. Pursuant to the Engagement Letter, Donnelly Penman received an initial advisory fee, an additional advisory fee, will receive a portion of its transaction fee at signing of the

Agreement (30%), with the remainder of its transaction fee payable at closing of the Acquisition, and in connection with the issuance of this fairness opinion will receive a fee from MBCN. Additionally, MBCN has agreed to reimburse Donnelly Penman for its out-of-pocket expenses (up to $7,500) and has agreed to indemnify Donnelly Penman and certain related persons against certain liabilities possibly incurred in connection with services performed.

Donnelly Penman has previously been engaged by MBCN within the last two years to provide advisory services. In October 2015, Donnelly Penman was engaged by MBCN in connection with an acquisition opportunity, which was not consummated, for which it received an initial retainer. Additionally, in March 2015, Donnelly Penman was engaged by MBCN in connection with an acquisition opportunity, which was not consummated, for which it received an initial retainer. Donnelly Penman has not been engaged by Liberty for any purpose.

In arriving at our opinion, we engaged in discussions with members of the management teams of MBCN and Liberty concerning the historical and current business operations, financial conditions and prospects of MBCN and Liberty, as well as engaged in discussions with independent Board Directors of MBCN, and we reviewed, among other things:

| • |  | the Agreement and the exhibits thereto;

| • |  | certain public information for MBCN, including each of its audited financial statements and Form 10-Ks for the years ended December 31, 2015, 2014 and 2013, the interim financial results for the six months ended June 30, 2016 and 2015 as disclosed in Form 10-Q, and the quarterly call reports for The Middlefield Banking Company for the periods March 31, 2016 and December 31, September 30, June 30, and March 31, 2015;

| • |  | the capital ownership structure of MBCN, including information on the recent issuance of common equity;

| • |  | the historical market prices and trading volume for MBCN’s publicly traded common stock;

| • |  | certain information, including historical and forecasted financial information, relating to earnings, dividends, assets, liabilities and prospects of MBCN furnished and deemed reasonable by senior management of MBCN;

| • |  | MBCN’s senior management projected earnings estimates for fiscal years 2016 through 2018, which Donnelly Penman extrapolated into fiscal year 2020, which were deemed reasonable by MBCN management;

| • |  | certain nonpublic information for Liberty made available from the due diligence process managed by its advisors, including its audited financial statements for the year ended December 31, 2015, 2014 and 2013, and publicly-available information for Liberty, including the quarterly call reports in each of the quarterly periods ended on June 30 and March 31, 2016, and December 31, September 30, June 30, and March 31, 2015;

| • |  | Liberty’s problem loans report as of March 31, and June 30, 2016;

| • |  | Liberty’s senior management projected earnings estimates for fiscal years 2016 through 2018, which Donnelly Penman extrapolated into fiscal year 2020, which were deemed reasonable by MBCN management;

| • |  | various valuation analyses of MBCN that Donnelly Penman performed including an analysis of comparable transactions, a dividend discount model analysis on a standalone basis for MBCN and on a pro forma basis including Liberty, and an analysis of comparable public companies to MBCN on a standalone and pro forma basis;

| • |  | a summary merger model displaying the pro forma impacts of the transaction to MBCN;

| • |  | a contribution analysis of MBCN and Liberty to the combined entity with regard to certain financial metrics as of June 30, 2016; and

| • |  | such other information, financial studies, analyses and investigations and such other factors that Donnelly Penman deemed relevant for the purposes of our opinion.

We have also held discussions with the senior management of MBCN regarding past and current business operations, regulatory relations, financial condition and future prospects of MBCN and such other matters as we have deemed relevant to our inquiry. We have also held discussions with the senior management of Liberty with regard to their business operations, regulatory relations, earnings results and future prospects. We have relied upon the management team of MBCN and Liberty as to the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefore) prepared by and provided to us by management of MBCN and Liberty and we have assumed, at the direction of MBCN and Liberty, that such forecasts and projections reflect the best currently available estimates and judgments of such management and that such forecasts and projections will be realized in the amounts and in the time periods currently estimated by such management and that they provide a reasonable basis upon which we could form our opinion. Such forecasts and projections were not prepared with the expectation of public disclosure. All such projected financial information is based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in such projected financial information. We have relied on this projected information without independent verification or analysis and do not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

In conducting our review and arriving at our opinion, we, with your consent, have relied, without independent investigation, upon the accuracy and completeness of all financial and other information provided to us by MBCN and Liberty or upon publicly available information. We do not undertake any responsibility for the accuracy, completeness or reasonableness of, or any obligation independently to verify, such information. We have further relied upon the assurance of management of MBCN and Liberty that they were unaware of any facts that would make the information provided or available to us incomplete or misleading in any respect. We did not make any independent evaluations, valuations or appraisals of the assets or liabilities of MBCN or Liberty. We did not review any individual credit files and assumed that the aggregate allowances for credit losses relating to the loans of MBCN and Liberty were and will continue to be adequate after the Acquisition to cover such losses. Our opinion is necessarily based upon economic and market conditions and other circumstances as they existed and evaluated by us on the date of this letter. We do not have any obligation to update this opinion, unless requested by you in writing to do so, and we expressly disclaim any responsibility to do so in the absence of such a written request.

No limitations were imposed by MBCN or Liberty on us or on the scope of our investigation or the procedures that were followed by us in rendering this opinion. The form and amount of the Total Consideration was determined through arms’ length negotiations between MBCN and Liberty. We were not requested to opine as to, and this opinion does not address, MBCN’s underlying business decision to proceed with or effect the Acquisition or the relative merits of the Acquisition compared to any alternative transaction that might be available to MBCN. Further, this letter does not constitute a recommendation to the shareholders of MBCN with respect to any approval of the Agreement or the Acquisition. Additionally, we were not requested to opine as to, and this opinion does not address, the fairness of the amount or nature of the compensation to any of Liberty’s officers, directors or employees.

In our analyses, we have made numerous assumptions with respect to industry performance, business and economic conditions, and other matters, many of which are beyond the control of MBCN and Liberty. The credit, financial and stock markets can experience unusual volatility and we express no opinion or view as to any potential effects of such volatility on MBCN, Liberty, or the Acquisition. No company or merger utilized in our analyses was identical to MBCN, Liberty, or the Acquisition. Accordingly, such analyses are not based solely on arithmetic calculations; rather, they involve complex considerations and judgments concerning differences in financial and operating characteristics of the relevant companies, the timing of the relevant mergers and prospective buyer interests, as well as other factors that could affect the public trading markets of companies to which MBCN is being compared. None of the analyses performed by us was assigned a greater significance than any other.

This opinion has been reviewed and approved by the Donnelly Penman Fairness Opinion Committee in conformity with our policies and procedures established under the requirement of Rule 5150 of the Financial Industry Regulatory Authority (FINRA).

Based upon and subject to the foregoing, we are of the opinion that, as of July 27, 2016, the Total Consideration to be paid by MBCN to Liberty shareholders under the Agreement is fair, from a financial point of view, to the shareholders of MBCN.

Very truly yours,

Donnelly Penman & Partners Inc.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

| (a) | Ohio General Corporation Law

Section 1701.13(E) of the Ohio Revised Code grants corporations broad powers to indemnify directors, officers, employees and agents. Section 1701.13(E) provides:

(E)(1) A corporation may indemnify or agree to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative, other than an action by or in the right of the corporation, by reason of the fact that he is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against expenses, including attorney’s fees, judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit, or proceeding, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, if he had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit, or proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful.

(2) A corporation may indemnify or agree to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that he is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against expenses, including attorney’s fees, actually and reasonably incurred by him in connection with the defense or settlement of such action or suit, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any of the following:

(a) Any claim, issue, or matter as to which such person is adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless, and only to the extent that, the court of common pleas or the court in which such action or suit was brought determines, upon application, that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court of common pleas or such other court shall deem proper;

(b) Any action or suit in which the only liability asserted against a director is pursuant to section 1701.95 of the Revised Code.

(3) To the extent that a director, trustee, officer, employee, member, manager, or agent has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in division (E)(1) or (2) of this section, or in defense of any claim, issue, or matter therein, he shall be indemnified against expenses, including attorney’s fees, actually and reasonably incurred by him in connection with the action, suit, or proceeding.

(4) Any indemnification under division (E)(1) or (2) of this section, unless ordered by a court, shall be made by the corporation only as authorized in the specific case, upon a determination that indemnification of the director, trustee, officer, employee, member, manager, or agent is proper in the circumstances because he has met

II-1

##### Table of Contents

the applicable standard of conduct set forth in division (E)(1) or (2) of this section. Such determination shall be made as follows:

(a) By a majority vote of a quorum consisting of directors of the indemnifying corporation who were not and are not parties to or threatened with the action, suit, or proceeding referred to in division (E)(1) or (2) of this section;

(b) If the quorum described in division (E)(4)(a) of this section is not obtainable or if a majority vote of a quorum of disinterested directors so directs, in a written opinion by independent legal counsel other than an attorney, or a firm having associated with it an attorney, who has been retained by or who has performed services for the corporation or any person to be indemnified within the past five years;

(c) By the shareholders;

(d) By the court of common pleas or the court in which the action, suit, or proceeding referred to in division (E)(1) or (2) of this section was brought.

Any determination made by the disinterested directors under division (E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this section shall be promptly communicated to the person who threatened or brought the action or suit by or in the right of the corporation under division (E)(2) of this section, and within ten days after receipt of such notification, such person shall have the right to petition the court of common pleas or the court in which such action or suit was brought to review the reasonableness of such determination.

(5) (a) Unless at the time of a director’s act or omission that is the subject of an action, suit, or proceeding referred to in division (E)(1) or (2) of this section, the articles or the regulations of a corporation state, by specific reference to this division, that the provisions of this division do not apply to the corporation and unless the only liability asserted against a director in an action, suit, or proceeding referred to in division (E)(1) or (2) of this section is pursuant to section 1701.95 of the Revised Code, expenses, including attorney’s fees, incurred by a director in defending the action, suit or proceeding shall be paid by the corporation as they are incurred, in advance of the final disposition of the action, suit, or proceeding upon receipt of an undertaking by or on behalf of the director in which he agrees to do both of the following:

(i) Repay such amount if it is proved by clear and convincing evidence in a court of competent jurisdiction that his action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation;

(ii) Reasonably cooperate with the corporation concerning the action, suit, or proceeding.

(b) Expenses, including attorney’s fees, incurred by a director, trustee, officer, employee, member, manager, or agent in defending any action, suit, or proceeding referred to in division (E)(1) or (2) of this section, may be paid by the corporation as they are incurred, in advance of the final disposition of the action, suit, or proceeding, as authorized by the directors in the specific case, upon receipt of an undertaking by or on behalf of the director, trustee, officer, employee, member, manager, or agent to repay such amount, if it ultimately is determined that he is not entitled to be indemnified by the corporation.

(6) The indemnification authorized by this section shall not be exclusive of, and shall be in addition to, any other rights granted to those seeking indemnification under the articles, the regulations, any agreement, a vote of shareholders or disinterested directors, or otherwise, both as to action in their official capacities and as to action in another capacity while holding their offices or positions, and shall continue as to a person who has ceased to be a director, trustee, officer, employee, member, manager, or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person.

(7) A corporation may purchase and maintain insurance or furnish similar protection, including, but not limited to, trust funds, letters of credit, or self-insurance, on behalf of or for any person who is or was a director,

II-2

##### Table of Contents

officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under this section. Insurance may be purchased from, or maintained with, a person in which the corporation has a financial interest.

(8) The authority of a corporation to indemnify persons pursuant to division (E)(1) or (2) of this section does not limit the payment of expenses as they are incurred, indemnification, insurance, or other protection that may be provided pursuant to divisions (E)(5),(6), and (7) of this section. Divisions (E)(1) and (2) of this section do not create any obligation to repay or return payments made by the corporation pursuant to divisions (E)(5),(6) or (7).

(9) As used in division (E) of this section, “corporation” includes all constituent entities in a consolidation or merger and the new or surviving corporation, so that any person who is or was a director, officer, employee, trustee, member, manager, or agent of such a constituent entity, or is or was serving at the request of such constituent entity as a director, trustee, officer, employee, member, manager, or agent of another corporation, domestic or foreign, nonprofit or for profit, a limited liability company, or a partnership, joint venture, trust, or other enterprise, shall stand in the same position under this section with respect to the new or surviving corporation as he would if he had served the new or surviving corporation in the same capacity.

| (b) | Articles of Incorporation and Regulations of Middlefield Banc Corp.

Middlefield Banc Corp.’s regulations contain the following provision having to do with indemnification of directors and officers:

ARTICLE VIII

INDEMNIFICATION AND INSURANCE

“SECTION 1 – INDEMNIFICATION. The Corporation shall indemnify, to the full extent then permitted by law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (and including, without limitation, any action, suit or proceeding by or in the right of the Corporation or otherwise), by reason of the fact that he is or was a member of the Board of Directors or an officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The Corporation shall pay, to the full extent then required by law, expenses, including attorney’s fees, incurred by a member of the Board of Directors in defending any such action, suit or proceeding as they are incurred, in advance of the final disposition thereof, and may pay, in the same manner and to the full extent then permitted by law, such expenses incurred by any other person. The indemnification and payment of expenses provided hereby shall not be exclusive of, and shall be in addition to, any other rights granted to those seeking indemnification under any law, the Articles, any agreement, vote of shareholders or disinterested members of the Board of Directors, or otherwise, both as to action in official capacities and as to action in another capacity while he or she is a member of the Board of Directors, or an officer, employee or agent of the Corporation, and shall continue as to a person who has ceased to be a member of the Board of Directors, trustee, officer, employee or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person.

SECTION 2 – INSURANCE. To the full extent then permitted by law and authorized by the Board of Directors, the Corporation may purchase and maintain insurance or furnish similar protection, including but not limited to trust funds, letters of credit or self-insurance, on behalf of or for any persons described in Section 1 of this article against any liability asserted against and incurred by any such person in any such capacity, or arising out of his status as such, regardless of whether the Corporation would have the power to indemnify such person against such liability. Insurance may be purchased from or maintained with a person in which the Corporation has a financial interest.

II-3

##### Table of Contents

SECTION 3 – AGREEMENTS. Upon approval by the Board of Directors, the Corporation may enter into agreements with any persons whom the Corporation may indemnify under these Regulations or under law and undertake thereby to indemnify such persons and to pay the expenses incurred by them in defending any action, suit or proceeding against them, regardless of whether the Corporation would have the power under law or these Regulations to indemnify any such person.

| (c) | Indemnification under private indemnification agreements

Directors and executive officers of Middlefield Banc Corp. entered into indemnification agreements with Middlefield Banc Corp. The indemnification agreements allow the directors and officers to select the most favorable indemnification rights provided under (1) Middlefield Banc Corp.’s articles of incorporation and regulations in effect on the date of the indemnification agreement or on the date expenses are incurred, (2) state law in effect on the date of the indemnification agreement or on the date expenses are incurred, (3) any liability insurance policy in effect when a claim is made or on the date expenses are incurred, and (4) any other indemnification arrangement otherwise available. The agreements cover all fees, expenses, judgments, fines, penalties, and settlement amounts paid in any matter relating to the director’s or officer’s role as Middlefield Banc Corp.’s director, officer, employee, agent or when serving as Middlefield Banc Corp.’s representative with another entity. Each indemnification agreement provides for the prompt advancement of all expenses incurred, subject to the obligation to repay those advances if the director or officer is later determined to be not entitled to indemnification. A form of the indemnification agreement is included as Exhibit 99.1 to the Form 10 Registration Statement, Amendment No. 1, filed by Middlefield Banc Corp. on June 14, 2001 and is incorporated herein by this reference.

Item 21. Exhibits and Financial Statement Schedules.

Item 22. Undertakings.

A. The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

II-4

##### Table of Contents

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. The undersigned Registrant hereby undertakes that prior to any public reoffering of the securities registered hereunder through use of a prospectus that is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

D. The Registrant undertakes that every prospectus (1) that is filed pursuant to paragraph C. immediately preceding, or (2) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

E. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

F. The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

G. The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
