I, John F. Ambrose, President & Chief Executive Officer of IGI, Inc.,
certify that:

1. I have reviewed this quarterly report on Form 10-Q of IGI, 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 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) evaluated the effectiveness of the registrant's disclosure controls
      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; 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:

      a) all significant deficiencies 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 data; and

      b) any fraud, whether or not material, that involves management or
      other employees who have a significant role in the registrant's
      internal controls;
