                  ATTACHMENT TO REVOLVING LINE OF CREDIT DATED
                               DECEMBER 27, 1993

      Interest will be billed monthly. Interim quarterly financial statements
on Bankers Insurance Group, Inc. and National Flood Certification Services,
Inc. are due to Marine Bank within 30 days of Quarter ends.

      National Flood Certification Services, Inc. agrees to provide a full
accounts receivable aging within 10 business days of each month end. That aging
should support the outstanding balance on the Revolving Line (80%) advance on
eligible receivables, (less than 120 days).

      If there are not sufficient receivables to support the outstanding
balance, then a check will accompany the receivables aging report, reducing the
outstanding balance to compliance (aging report and check, if required, are due
and payable within 10 days of each month end). If there are sufficient
receivables, reflected in the report, to warrant an additional advance,
according to the above formula, that request may accompany the aging report up
to the maximum $600,000.00 approved line.

      Audited year end financial statements on Bankers Insurance Group, Inc.
and Bankers Insurance Company are due by May 31 of the year following the year
end.

      Dated this 23rd Day of December 1993.
