The Merger Agreement provides for the merger of Mainland Bank with and into Investar Bank, with Investar Bank as the entity surviving the merger. Following the merger, Investar Bank will continue as a wholly-owned subsidiary of Investar.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Under the terms of the Merger Agreement, all of the issued and outstanding shares of Mainland Bank common stock will be converted into and represent the right to receive aggregate merger consideration consisting of an aggregate of 763,849 shares of Investar common stock (the &#8220;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Exchange Pool</font><font style="font-family:inherit;font-size:10pt;">&#8221;), which is subject to adjustment as described below. As a result of the merger, holders of shares of Mainland Bank common stock are expected to receive 3.0389 shares of Investar common stock for each share of Mainland Bank common stock held immediately prior to the merger. Mainland Bank shareholders will receive cash in lieu of fractional shares.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The aggregate merger consideration is subject to a downward adjustment to the extent that the aggregate expenses of Mainland Bank as described in the Merger Agreement (the &#8220;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Mainland Transaction Expenses</font><font style="font-family:inherit;font-size:10pt;">&#8221;) exceed $1,075,000 (the &#8220;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Expense Cap</font><font style="font-family:inherit;font-size:10pt;">&#8221;). If the aggregate Mainland Transaction Expenses are more than the Expense Cap, then the Exchange Pool will be reduced by a number of shares of Investar common stock equal to the quotient obtained by dividing: (i) the difference between the Mainland Transaction Expenses and the Expense Cap by (ii) $26.54.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Merger Agreement contains customary representations and warranties and covenants by the parties. Included among the covenants contained in the Merger Agreement is the obligation of Mainland Bank not to solicit, initiate, encourage or otherwise facilitate any inquiries or other proposals related to, participate in any discussions or negotiations regarding or furnish any nonpublic information related to, any alternative business combination transaction, subject to certain exceptions. In the event that Mainland Bank receives an unsolicited proposal with respect to an alternative business combination transaction that its board of directors determines to be superior to the merger, Investar will have an opportunity to match the terms of such proposal, subject to certain requirements.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The assertions embodied in the representations and warranties contained in the Merger Agreement were made solely for purposes of the Merger Agreement, and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating terms. Moreover, the representations and warranties are subject to contractual standards of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between Investar, Investar Bank and Mainland Bank, rather than establishing matters as facts. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding Investar, Investar Bank or Mainland Bank at the time they were made or otherwise. The representations and warranties of the parties will not survive the closing.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Consummation of the transactions contemplated by the Merger Agreement is subject to various customary conditions, including, without limitation (i) the approval of the shareholders of Mainland Bank, (ii) the receipt of certain regulatory approvals, (iii) the accuracy of the representations and warranties of the parties and compliance by the parties with their respective covenants and obligations under the Merger Agreement (subject to customary materiality qualifiers), and (iv) the absence of a material adverse effect with respect to Mainland Bank, Investar and Investar Bank.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Merger Agreement contains certain termination rights, including the right, subject to certain exceptions, of either party to terminate the Merger Agreement if the closing has not occurred by June 30, 2019, and the right of Mainland Bank to terminate the Merger Agreement, subject to certain conditions, to accept a business combination transaction deemed by its board of directors to be superior to the proposed merger. The Merger Agreement is subject to termination by either party under certain conditions and provides for the payment of a termination fee of $816,000 payable by Mainland Bank upon termination of the Merger Agreement under certain circumstances.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The foregoing summary of the Merger Agreement is qualified in its entirety by reference to the complete text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference in its entirety.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Merger Agreement has been approved by the boards of directors of each of Investar, Investar Bank and Mainland Bank, and the Merger Agreement has been executed and delivered by each of the parties.

The support agreements provide generally that the executing party will not solicit the former employees or customers of Mainland Bank, or otherwise engage in banking activities, for a period of two years following the closing date of the merger, subject to certain exceptions. The voting agreements generally provide that the executing party will vote his or her shares in favor of the Merger Agreement and the transactions contemplated thereby at any meeting of the Mainland Bank shareholders called to consider such transaction(s). The foregoing description of the voting and support agreements do not purport to be complete, and is qualified in its entirety by reference to the forms of voting and support agreements, which are attached hereto as Exhibit 10.1 and Exhibit 10.2, respectively, and which are incorporated by reference herein.</font></div><div style="line-height:120%;padding-top:18px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Item 7.01  Regulation FD Disclosure</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">A press release issued by Investar announcing the transaction is attached as Exhibit 99.1 to this Current Report on Form 8-K.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">As provided in General Instruction B.2 to Form 8-K, the information furnished in Exhibit 99.1 of this Current Report on Form 8-K will not be deemed &#8220;filed&#8221; for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the &#8220;Exchange Act&#8221;), or otherwise subject to the liabilities of that section, and such information will not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, regardless of any general incorporation language in such filings.</font></div><div style="line-height:120%;padding-top:18px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Forward-Looking Statements</font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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 &#8220;may,&#8221; &#8220;will,&#8221; &#8220;anticipate,&#8221; &#8220;estimate,&#8221; &#8220;expect,&#8221; &#8220;project,&#8221; &#8220;intend,&#8221; &#8220;plan,&#8221; &#8220;believe,&#8221; &#8220;target,&#8221; &#8220;forecast,&#8221; and other words and terms of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Investar 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.

Item 1.01  Entry into a Material Definitive Agreement.
On October 10, 2018, Investar Holding Corporation (NASDAQ: ISTR) ("
Investar
") and its wholly-owned subsidiary, Investar Bank, Baton Rouge, Louisiana ("
Investar Bank
") entered into an Agreement and Plan of Reorganization (together with all exhibits thereto, the  "
Merger Agreement
") with Mainland Bank, Texas City, Texas ("
Mainland Bank
").  The Merger Agreement provides for the merger of Mainland Bank with and into Investar Bank, with Investar Bank as the entity surviving the merger. Following the merger, Investar Bank will continue as a wholly-owned subsidiary of Investar.
Under the terms of the Merger Agreement, all of the issued and outstanding shares of Mainland Bank common stock will be converted into and represent the right to receive aggregate merger consideration consisting of an aggregate of 763,849 shares of Investar common stock (the "
Exchange Pool
"), which is subject to adjustment as described below. As a result of the merger, holders of shares of Mainland Bank common stock are expected to receive 3.0389 shares of Investar common stock for each share of Mainland Bank common stock held immediately prior to the merger. Mainland Bank shareholders will receive cash in lieu of fractional shares.
The aggregate merger consideration is subject to a downward adjustment to the extent that the aggregate expenses of Mainland Bank as described in the Merger Agreement (the "
Mainland Transaction Expenses
") exceed $1,075,000 (the "
Expense Cap
"). If the aggregate Mainland Transaction Expenses are more than the Expense Cap, then the Exchange Pool will be reduced by a number of shares of Investar common stock equal to the quotient obtained by dividing: (i) the difference between the Mainland Transaction Expenses and the Expense Cap by (ii) $26.54.
The Merger Agreement contains customary representations and warranties and covenants by the parties. Included among the covenants contained in the Merger Agreement is the obligation of Mainland Bank not to solicit, initiate, encourage or otherwise facilitate any inquiries or other proposals related to, participate in any discussions or negotiations regarding or furnish any nonpublic information related to, any alternative business combination transaction, subject to certain exceptions. In the event that Mainland Bank receives an unsolicited proposal with respect to an alternative business combination transaction that its board of directors determines to be superior to the merger, Investar will have an opportunity to match the terms of such proposal, subject to certain requirements.
The assertions embodied in the representations and warranties contained in the Merger Agreement were made solely for purposes of the Merger Agreement, and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating terms. Moreover, the representations and warranties are subject to contractual standards of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between Investar, Investar Bank and Mainland Bank, rather than establishing matters as facts. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding Investar, Investar Bank or Mainland Bank at the time they were made or otherwise. The representations and warranties of the parties will not survive the closing.
Consummation of the transactions contemplated by the Merger Agreement is subject to various customary conditions, including, without limitation (i) the approval of the shareholders of Mainland Bank, (ii) the receipt of certain regulatory approvals, (iii) the accuracy of the representations and warranties of the parties and compliance by the parties with their respective covenants and obligations under the Merger Agreement (subject to customary materiality qualifiers), and (iv) the absence of a material adverse effect with respect to Mainland Bank, Investar and Investar Bank.
