of the Federal Reserve System under the Bank Holding Company Act of 1956, having become the holding company of The Middlefield Banking Company on or about January&nbsp;13, 1989. Our principal executive offices are located at 15985 East High Street,
Middlefield, Ohio and our telephone number is (440)&nbsp;632-1666. We conduct business primarily through our bank subsidiaries: The Middlefield Banking Company, a commercial bank chartered under Ohio law in 1901 and operating in northeastern Ohio,
and Emerald Bank, also a commercial bank chartered under Ohio law, operating in central Ohio. Emerald Bank was established in June 2004 and acquired by Middlefield Banc Corp. on April&nbsp;19, 2007. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2013 we obtained regulatory approval to merge Emerald Bank into The Middlefield Banking Company, which we expect will eliminate duplicate
expenses and enhance operating efficiencies. We anticipate that the merger will be completed on or shortly after January&nbsp;20, 2014. Although delay is possible, we currently do not anticipate any material delays in completion of the merger, and
if any delays do occur we anticipate that they will be insignificant. We expect that the merger will have no impact on the business done by Emerald Bank. Emerald Bank&#146;s two offices are located in Franklin County in central Ohio. After the
merger, those two offices will be branches of The Middlefield Banking Company. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We engage in a general commercial banking business in
northeastern Ohio and in central Ohio, serving small and medium-sized businesses, professionals, small business owners, and retail customers with checking, savings, and negotiable order of withdrawal (NOW) accounts, money market accounts, time
certificates of deposit, commercial loans, real estate loans, and various types of consumer loans, safe deposit facilities, and travelers&#146; checks. We offer online banking and bill payment services to individuals and online cash management
services to business customers through websites at www.middlefieldbank.com and www.emeraldbank.com. Our business loans include operational and working capital loans, loans to finance capital purchases, term business loans, selected guaranteed or

FACTORS </B></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Investing in our shares involves significant risks. If you are considering purchasing or selling our shares, you should
consider (<I>x</I>)&nbsp;the risks described under the heading &#147;Item 1A. Risk Factors&#148; in Part I of our most recent Annual Report on Form 10-K and (<I>y</I>)&nbsp;any risks described under the heading &#147;Item 1A. Risk Factors&#148; in
Part II of our Quarterly Reports on Form 10-Q filed with the SEC after we filed our most recent Annual Report on Form 10-K, as well as any amendments thereto reflected in subsequent filings with the SEC. You should also carefully consider the
cautionary statements under the heading &#147;Cautionary Note About Forward-Looking Statements.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Because of regulatory criticisms of
our banking practices relating to capital, asset quality, compliance, and other issues, we have made commitments to or entered into agreements with the Federal Reserve Bank of Cleveland, the FDIC, and the Ohio Division of Financial Institutions, for
example committing to maintain total risk-based capital of at least 12% and leverage capital of at least 7.25%, both at Middlefield Banc Corp. and at The Middlefield Banking Company, committing to make improvements in our consumer compliance
management systems, and agreeing to specified improvements in our information technology and information security processes. We are taking the actions that we believe are necessary to correct the conditions that led to the regulatory criticisms,
seeking to satisfy all of the terms of our regulatory commitments and agreements. But as long as those commitments and agreements remain in effect we will be subject to enhanced regulatory scrutiny. We expect that the enhanced minimum capital
requirements will apply for the foreseeable future. If the conditions that led to the regulatory criticisms are not corrected or if other factors lead the state or Federal bank regulatory authorities to take action, we could become subject to formal
supervisory enforcement actions by the Federal Reserve Bank of Cleveland, by the FDIC, or by the Ohio Division of Financial Institutions. Additional information concerning applicable regulatory limitations and commitments and agreements we have
entered into with state and Federal bank regulatory agencies is contained in the documents incorporated herein by reference. For more information, see &#147;Information Incorporated by Reference.&#148; </P>

of our common stock does not purport to be a complete statement of the rights of our stockholders. This summary is qualified in its entirety by reference to our Second Amended and Restated Articles of Incorporation and our regulations, which are
incorporated by reference herein, and to the relevant provisions of Ohio law. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Authorized shares</B>. Our authorized capital stock
consists of 10,000,000 common shares, without par value. There were 2,026,568 shares outstanding on September&nbsp;30, 2013, held of record by approximately 1,051 stockholders. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Dividends</B>. Stockholders of an Ohio corporation are entitled to dividends when, as, and if declared by the corporation&#146;s board of
directors. Our ability to obtain funds for the payment of dividends and for other cash requirements largely depends on the amount of dividends paid by our subsidiaries. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Voting</B>. Each share of our common stock is entitled to one vote on all matters submitted to stockholders for consideration. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Number and election of directors</B>. The articles of incorporation or regulations of an Ohio corporation determine the authorized number
of the corporation&#146;s directors, but there generally must be at least three directors. Our regulations provide that the authorized number of directors may be fixed or changed within a range of five to 25 either by the board or &#150; at an
annual meeting &#150; by the affirmative vote of holders of a majority of the voting power of the shares represented at the meeting. Directors are elected by plurality vote, meaning the director nominees receiving the greatest number of votes are
elected. Directors may be elected by stockholders at annual meetings only. Stockholders do not have the right to vote cumulatively in the election or removal of directors. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Classification of the board and director terms</B>. An Ohio corporation&#146;s articles of incorporation or regulations may provide for the
classification of directors into either two or three classes, but each class must consist of at least three directors and none of the classes may have a term exceeding three years. Our board is divided into three classes of directors, each class
serving a three-year term. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Nomination of directors</B>. Our regulations impose restrictions on stockholders&#146; power to nominate

may be called by the Chairman of the Board, by the President, by the board acting at a meeting, by a majority of directors acting without a meeting, or by stockholders holding at least 25% of our shares. The request for a special meeting must be in
writing delivered to the President or the corporate Secretary and it must state the purpose for which the meeting is to be held. Our regulations contain in Article I, section 8 detailed rules governing the conduct of business at a meeting, whether
the meeting is an annual or special meeting. Among other things, these rules affirm the presiding officer&#146;s authority to determine who, other than stockholders, may attend the meeting and the presiding officer&#146;s authority to control the
conduct of the meeting, including the authority to remove a disruptive stockholder. Article I, section 8 also outlines the procedure to be followed by a stockholder who wishes to propose business for consideration and vote at a meeting. </P>

the stockholder&#146;s proposed action will not be considered. Specifically, the stockholder must give timely notice, meaning the stockholder&#146;s notice must be received by the Secretary at least 60 but no more than 120 days before the date in
the current year corresponding to the date of mailing of the proxy statement in the preceding year. But if the current year&#146;s annual meeting date is changed by more than 30 days from the preceding year&#146;s annual meeting date, the
stockholder&#146;s notice will be considered timely if it is received by the Secretary a reasonable time &#150; no fewer than 30 days &#150; before we mail the proxy statement for the current year&#146;s annual meeting. Identical deadlines apply to

is approved by the board before or at the same time the person or entity becomes the owner of 10% or more of the shares, or (<I>y</I>)&nbsp;if the board approves the transaction by a vote of two thirds of its members and a majority of the so-called
continuing directors, and if the per share price to be paid in the transaction by the interested party is an amount in cash equal to or greater than the highest price paid by the interested party for its shares. A continuing director is one who was
a director before the interested party became the owner of 4% of the shares. A person recommended by a majority of continuing directors to succeed a continuing director would also be considered a continuing director. Article Sixth creates incentive
for an acquiror to negotiate the terms of an acquisition directly with the board before the acquiror becomes a significant stockholder. Bypassing board approval can have adverse consequences, such as a greater stockholder approval threshold, a
requirement to pay a greater price than the acquiror might otherwise be willing to pay, potential resistance by the board, increased potential for delays, and potentially greater transaction costs. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Amendment of articles of incorporation</B>. An Ohio corporation&#146;s articles of incorporation may be amended by the affirmative vote of
two thirds of the shares entitled to vote on the proposal. However, the corporation&#146;s articles of incorporation may instead impose a different approval threshold, but never less than a majority of the shares entitled to vote. Our articles of
incorporation permit amendment by a majority of the voting power, except that Article Sixth alone may be amended solely by adherence to the special voting requirements discussed above. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Amendment of regulations</B>. By the affirmative vote of a majority of shares entitled to vote, stockholders of an Ohio corporation may
amend the regulations or adopt revised regulations. Stockholders may amend the regulations without a meeting by the affirmative vote of the holders of two thirds of the shares entitled to vote on the proposal. An Ohio corporation&#146;s articles of
incorporation or regulations may change the required stockholder vote but may not allow approval by less than a majority of the voting power. Our articles of incorporation provide that the regulations may be amended by the affirmative vote of
stockholders entitled to exercise a majority of the voting power if and only if the board first approves the amendment. Otherwise, the affirmative vote of stockholders entitled to exercise two thirds of the voting power is necessary. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Preemptive rights</B>. Our articles of incorporation explicitly provide that stockholders do not have preemptive rights. If a
corporation&#146;s stockholders have preemptive rights, this means the corporation must first give to stockholders the opportunity to purchase shares in proportion to their current holdings at a fixed price before the corporation may offer the
shares for sale to the public. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Liquidation rights</B>. If a liquidation, dissolution, or winding up occurs, each stockholder would be

or its stockholders under the Ohio General Corporation Law unless it is proved by clear and convincing evidence that the director did not act (<I>x</I>)&nbsp;in good faith, (<I>y</I>)&nbsp;in a manner he or she reasonably believed to be in or not
opposed to the best interests of the corporation, or (<I>z</I>)&nbsp;with the care that an ordinarily prudent person in a like position would have used under similar circumstances. Additionally, a director is personally liable if and only if it is
proved by clear and convincing evidence that the director&#146;s act or omission occurred with deliberate intent to cause injury to the corporation or with reckless disregard for the corporation&#146;s best interests. Under limited circumstances
stated in section 1701.95 of the Ohio General Corporation Law however, a director of an Ohio corporation can be absolutely liable to the corporation, for example if the director votes in favor of an illegal dividend. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Changes in control</B>. A number of provisions within our articles of incorporation and regulations could have the effect of preventing,
delaying, or making more costly a change in control, whether the change in control is undertaken by a tender offer, a proxy contest, open-market purchases, or otherwise in a transaction not first approved by the board of directors. The provisions
having an anti-takeover impact could discourage altogether a takeover attempt that is not first approved by our board of directors, even though individual stockholders might consider a takeover to be in stockholders&#146; best interests and even
though a takeover might involve payment of a substantial premium to stockholders over the prevailing stock price. Accordingly, stockholders who wish to benefit from a takeover or takeover attempt might not have the opportunity to do so. These
provisions could also make removal of directors and management more difficult. Provisions in our articles of incorporation and regulations that could reduce our vulnerability to takeover attempts that are not first negotiated with and approved by
the board of directors and that could have an anti-takeover impact include these &#150; </P>

9.7% of the shares of our common stock. To the best of our knowledge, the selling stockholder and affiliates own no shares of our common stock other than the 196,635 shares offered by this prospectus. As explained under the subheading
&#147;Background of our issuance of shares to the selling stockholder,&#148; below, if the selling stockholder and affiliates acquire additional shares and increase their ownership to 10% or more of our common stock, whether acquiring the shares on
the open market or from us, we will become subject to restrictions discussed under that subheading. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Of the 196,635 shares being offered
by means of this prospectus, the selling stockholder may offer and sell any or all of the shares in any of the types of transactions described under the caption &#147;Plan of Distribution.&#148; We do not know when or in what amounts the selling
stockholder may offer shares for sale. It is possible that the selling stockholder will not sell any of the shares. Because the selling stockholder may sell all of the shares, some of the shares, or none of the shares, and because we have been
advised by the selling stockholder that there currently are no agreements, arrangements, or understandings for the sale of any of the shares, we cannot estimate the number of shares that will be held by the selling stockholder after completion of
the offering. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Except for the selling stockholder&#146;s acquisition of shares from us, which occurred in April of 2012, the selling
stockholder has not within the past three years had any position, office, or other material relationship with us. By the terms of the agreement under which we issued shares to the selling stockholder, however, the selling stockholder obtained the
right to designate one person to serve as a director of Middlefield Banc Corp. and as a director of our subsidiary banks. That designee, Mr.&nbsp;Joseph&nbsp;J. Thomas, was appointed in February of 2013 and is currently serving as a director in the
class whose term expires at the annual meeting in 2015. Directors and executive officers who were serving in those capacities when the selling stockholder&#146;s director designee was appointed are required to vote in favor of the director designee
at any meeting at which the designee stands for election. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">By offering shares using this prospectus the selling stockholder and any

shares in the private placement, selling 138,150 shares in 2011, followed by a sale of 93,050 shares on April&nbsp;17, 2012 to the selling stockholder and a sale of another 103,585 shares to the
selling stockholder on April&nbsp;30, 2012. The private placement concluded on March&nbsp;8, 2013 with a sale of 13,320 shares to an institutional investor, completing the sale to that investor under the terms of a subscription agreement it entered
into in August of 2011. All sales in the private placement occurred at $16 per share. We made offers and sales solely to those qualifying as accredited investors, as defined in Rule 501 of the SEC&#146;s Regulation D. Our sale of shares was exempt
from registration under the Securities Act of 1933 because we relied on the private placement exemption in section 4 of that statute and on Rule 506 of Regulation D. Of the 348,105 shares sold in the private placement, we agreed to register for
resale solely the 196,635 shares sold to the selling stockholder. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our sale of 196,635 shares to the selling stockholder occurred
according to the terms of an August&nbsp;15, 2011 Stock Purchase Agreement with Bank Opportunity Fund LLC, an affiliate of the selling stockholder. As amended by amendments one through six, the Stock Purchase Agreement allowed Bank Opportunity Fund
LLC to acquire up to 24.99% of our common stock, assuming all necessary approvals of stockholders and federal and state bank regulatory authorities had first been obtained and assuming all conditions specified in the Stock Purchase Agreement had
been satisfied or waived. At the same time we entered into the Stock Purchase Agreement we and the directors and executive officers of Middlefield Banc Corp. also entered into a Purchaser&#146;s Rights and Voting Agreement with Bank Opportunity Fund
LLC. The Purchaser&#146;s Rights and Voting Agreement affirmed the right of Bank Opportunity Fund LLC to designate a director of Middlefield Banc Corp. and its subsidiary banks and the obligation of our directors and executive officers to vote in
favor of the director designee at any meeting at which the designee stands for election. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2011 Bank Opportunity Fund LLC began the
process of obtaining regulatory clearance for the acquisition of up to 24.99% of our common stock. On or about January&nbsp;14, 2013 the Ohio Division of Financial Institutions and the Federal Reserve Bank of Cleveland granted to Bank Opportunity
Fund LLC regulatory clearance to acquire up to 24.99% of our stock. The regulatory clearances were granted subject to conditions, however, including the condition that the shares be held by the selling stockholder rather than by Bank Opportunity
Fund LLC. The regulatory clearance granted by the Ohio Division of Financial Institutions includes conditions that would have a direct impact on us if the shares held by Bank Opportunity Fund LLC and affiliates, including the selling stockholder,
were to equal or exceed 10% of our common stock. Specifically, for three years after Bank Opportunity Fund LLC and affiliates become an owner of 10% or more of our stock we would have to obtain advance approval of the Ohio Division of Financial
Institutions for The Middlefield Banking Company to pay a dividend to us, and for 12 months we would have to obtain advance written approval of the Ohio Division of Financial Institutions for any changes in the composition of our board or executive
management. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">When regulatory clearance was obtained on January&nbsp;14, 2013, the selling stockholder had already acquired 196,635 shares
(at the time constituting approximately 9.9% of our stock), purchasing the shares in April of 2012 with the expectation that those shares would later be transferred to Bank Opportunity Fund LLC after regulatory clearance is obtained. Although we
disclosed in a Form 8-K Current Report filed with the SEC on January&nbsp;18, 2013 that sale of additional shares under the terms of the Stock Purchase Agreement will not occur, if the selling stockholder and affiliates nevertheless increase their
ownership to 10% or more of our common stock, whether acquiring the shares on the open market or otherwise, we will become subject to the restrictions under the terms of the regulatory clearance granted by the Ohio Division of Financial
Institutions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We agreed in the Stock Purchase Agreement to register for resale all shares sold under that agreement, agreeing to file
with the SEC under the Securities Act of 1933 a registration statement for the offer and sale of the shares. This prospectus forms a part of the registration statement that we filed with the SEC to enable resale of the shares by the selling
stockholder. We also agreed to use reasonable best efforts to cause the registration statement to be declared effective and to keep it continuously effective and in compliance with the Securities Act of 1933 until the shares issued to the selling
stockholder are sold, or until the shares may be sold by the selling stockholder in reliance on SEC Rule 144 without limitation on the volume or manner of sale, or until the shares cease to be outstanding, or until the shares are sold in a private
transaction in which the transferee does not acquire the transferor&#146;s rights under the Stock Purchase Agreement. By assignment from Bank Opportunity Fund LLC, the selling stockholder acquired the rights of that affiliated entity under the Stock
Purchase Agreement, as amended by amendments one through six, including the right to have us register for resale all of the 196,635 shares and the right to designate a director for service on our board and on the board of The Middlefield Banking
Company. References throughout this prospectus to the selling stockholder mean Eric D. Hovde and any affiliate of Mr.&nbsp;Hovde to whom or to which he may transfer both some or all of the 196,635 shares and the right to have us register the shares
for resale. </P>
