<p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;">This Current Report on Form 8-K may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are typically identified by words or phrases such as &ldquo;may,&rdquo; &ldquo;will,&rdquo; &ldquo;anticipate,&rdquo; &ldquo;estimate,&rdquo; &ldquo;expect,&rdquo; &ldquo;project,&rdquo; &ldquo;intend,&rdquo; &ldquo;plan,&rdquo; &ldquo;believe,&rdquo; &ldquo;target,&rdquo; &ldquo;forecast,&rdquo; and other words and terms of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Business First cautions readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements. Such forward-looking statements include, but are not limited to, statements about the benefits of the merger of Business First and MBI, including future financial and operating results; Business First&rsquo;s plans, objectives, expectations and intentions and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include risks and uncertainties relating to: (i) the risk that the businesses will not be integrated successfully; (ii) the risk that the cost savings and any other synergies from the transaction may not be fully realized or may take longer to realize than expected; (iii) disruption from the transaction making it more difficult to maintain relationships with customers, employees or vendors; (iv) the diversion of management time on merger-related issues; and (v) other factors which Business First discusses or refers to in the &ldquo;Risk Factors&rdquo; section of its most recent Annual Report on Form 10-K filed with the Commission. Each forward-looking statement speaks only as of the date of the particular statement and Business First undertakes no obligation to update or revise its forward-looking statements, whether as a result of new information, future events or otherwise.</p>

Forward-Looking Statements
This Current Report on Form 8-K may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are typically identified by words or phrases such as "may," "will," "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," "target," "forecast," and other words and terms of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Business First cautions readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements. Such forward-looking statements include, but are not limited to, statements about the benefits of the merger of Business First and MBI, including future financial and operating results; Business First's plans, objectives, expectations and intentions and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include risks and uncertainties relating to: (i) the risk that the businesses will not be integrated successfully; (ii) the risk that the cost savings and any other synergies from the transaction may not be fully realized or may take longer to realize than expected; (iii) disruption from the transaction making it more difficult to maintain relationships with customers, employees or vendors; (iv) the diversion of management time on merger-related issues; and (v) other factors which Business First discusses or refers to in the "Risk Factors" section of its most recent Annual Report on Form 10-K filed with the Commission. Each forward-looking statement speaks only as of the date of the particular statement and Business First undertakes no obligation to update or revise its forward-looking statements, whether as a result of new information, future events or otherwise.
