I, David A. Meinert, Executive Vice President and Chief Financial Officer,
certify that:



1. I have reviewed this quarterly report on
Form 10-Q of MidWestOne Financial Group, Inc.;



2. Based
on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with
respect to the period covered by this report;



3. Based on my
knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods
presented in this report;



4. The registrants other
certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:



(a) Designed such disclosure controls and procedures, or caused such
disclosure controls to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in
which this report is being prepared;



(b) Evaluated the
effectiveness of the registrants disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on
such evaluation; and



(c) Disclosed in this report any change
in the registrants internal control over financial reporting that occurred during the registrants most recent fiscal quarter (the registrants fourth fiscal quarter in the case of an annual report) that has materially affected, or
is reasonably likely to materially affect, the registrants internal control over financial reporting; and



5. The registrants other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting,
to the registrants auditors and the audit committee of registrants board of directors (or persons performing the equivalent function):



(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably
likely to adversely affect the registrants ability to record, process, summarize and report financial information; and



(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrants internal control
over financial reporting.
