                                 CERTIFICATIONS

I, H. Douglas Chaffin, President and Chief Executive Officer of MBT Financial
Corp., certify that:

     1.  I have reviewed this Amendment No. 1 to Annual Report on Form 10-K/A of
         MBT Financial Corp.;

     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.  INTENTIONALLY OMITTED;

     4.  The registrant's other certifying officer(s) 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)) and internal
         control over financial reporting (as defined in Exchange Act Rules
         13a-15(f) and 15d-15(f)) for the registrant and have:

              (a) Designed such disclosure controls and procedures, or caused
              such disclosure controls and procedures 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) Designed such internal control over financial reporting, or
              caused such internal control over financial reporting to be
              designed under our supervision, to provide reasonable assurance
              regarding the reliability of financial reporting and the
              preparation of financial statements for external purposes in
              accordance with generally accepted accounting principles;

              (c) 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

              (d) 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(s) 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 the
         registrant's board of directors (or persons performing the equivalent
         functions):

              (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.
