                                 CERTIFICATIONS

I, Nimrod T. Frazer, Chairman of the Board of Directors and Chief Executive
Officer, certify that:

    1.   I have reviewed this annual report on Form 10-K of The Enstar Group,
Inc.;

    2.   Based on my knowledge, this annual 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
annual report;

    3.   Based on my knowledge, the financial statements, and other financial
information included in this annual 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 annual 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-14 and 15d-14) for the registrant and we have:

               (a) Designed such disclosure controls and procedures, or caused
         such 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 annual
         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 that has materially affected,
         or is reasonably likely to materially affect, the registrant's internal
         control over financial reporting;

    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 equivalent functions):

               (a) All significant deficiencies and material weaknesses in the
         design or operation of internal controls 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.
