Interstate Bank Great West Center, 1800 Sixth Avenue North, Billings, Montana 59101.  Among the matters to be considered for approval at the Annual Meeting is a Plan of Domestication and Conversion to change the Company&#8217;s state of incorporation from Montana to Delaware (the &#8220;Plan of Conversion&#8221;).</font></div><div style="margin-bottom:8pt"><font style="color:#000000;font-family:'Calibri',sans-serif;font-size:10pt;font-weight:700;line-height:110%">These definitive additional materials are being filed with the Commission and provided to shareholders to stress the importance of voting your shares in connection with the Annual Meeting because of the high voting standard that is required to approve the Plan of Conversion and to inform you that we engaged a proxy advisory firm to assist us with the solicitation of proxies for the Annual Meeting due to this higher voting standard.</font></div><div style="margin-bottom:8pt;text-align:center"><font style="color:#f58220;font-family:'Calibri',sans-serif;font-size:10pt;font-weight:700;line-height:110%">PROXY SOLICITOR</font></div><div style="margin-bottom:8pt"><font style="color:#000000;font-family:'Calibri',sans-serif;font-size:10pt;font-weight:400;line-height:110%">We have engaged MacKenzie Partners, Inc., 1407 Broadway, New York, New York 10018 (&#34;MacKenzie&#34;) to solicit proxies on our behalf for a fee of $15 thousand, plus reimbursement of customary disbursements.

It is therefore critical that your votes be represented at the Annual Meeting to provide the Plan of Conversion with the highest likelihood to be approved at the Annual Meeting.
