business strategies and intended results and future performance. Forward-looking statements are preceded by terms such as &#147;expects,&#148; &#147;believes,&#148; &#147;anticipates,&#148; &#147;intends&#148; and similar expressions, as well as any
statements related to future expectations of performance or conditional verbs, such as &#147;will,&#148; &#147;would,&#148; &#147;should,&#148; &#147;could&#148; or &#147;may.&#148; </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Forward-looking statements are not a guarantee of future performance and actual future results could differ materially from those contained in forward-looking
information. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of Middlefield&#146;s control. Numerous
uncertainties, risks, and changes could cause or contribute to Middlefield&#146;s actual results, performance, and achievements to be materially different from those expressed or implied by the forward-looking statements. Factors that may cause or
contribute to these differences include, without limitation, the possibility that the closing of the proposed transaction is delayed or does not occur at all because conditions to the transaction are not obtained or satisfied on a timely basis or at
all; the possibility that the anticipated benefits of the transaction are not realized when expected or at all; Middlefield&#146;s failure to integrate Liberty Bancshares, Inc. and Liberty National Bank with Middlefield and The Middlefield Banking
Company in accordance with expectations; deviations from performance expectations related to Liberty Bancshares, Inc. and Liberty National Bank; diversion of management&#146;s attention on the proposed transaction; general economic conditions in
markets where Middlefield and Liberty Bancshares, Inc. conduct business, which could materially impact credit quality trends; effects of the <FONT STYLE="white-space:nowrap">COVID-19</FONT> pandemic on the local, national, and international economy,
Middlefield&#146;s or Liberty&#146;s organization and employees, and Middlefield&#146;s and Liberty&#146;s customers and suppliers and their business operations and financial condition; disruptions in the mortgage and lending markets and significant
or unexpected fluctuations in interest rates related to <FONT STYLE="white-space:nowrap">COVID-19</FONT> and governmental responses, including financial stimulus packages; general business conditions in the banking industry; the regulatory
environment; general fluctuations in interest rates; demand for loans in the market areas where Middlefield and Liberty conduct business; rapidly changing technology and evolving banking industry standards; competitive factors, including increased
competition with regional and national financial institutions; and new service and product offerings by competitors and price pressures; and other factors disclosed periodically in Middlefield&#146;s filings with the Securities and Exchange
Commission (the &#147;SEC&#148;). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Because of the risks and uncertainties inherent in forward-looking statements, readers are cautioned not to place undue
reliance on them, whether included in this release or made elsewhere from time to time by Middlefield. Forward-looking statements speak only as of the date made, and Middlefield assumes no duty and does not undertake to update forward-looking
statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Middlefield provides further detail regarding these risks and uncertainties in the latest&nbsp;Annual Report, including in the risk factors
section of Middlefield&#146;s latest Annual Report on Form <FONT STYLE="white-space:nowrap">10-K,</FONT> as well as in subsequent SEC filings, available on the SEC&#146;s website at www.sec.gov. </P>
