CERTIFICATION

I, Richard D. Mangiarelli, certify the following:

      1.    I have reviewed this annual report on Form 10-KSB of Global Resource
            Corporation;

      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 Global Resource Corporation as of, and for, the
            periods presented in this annual report;

      4.    I am responsible for establishing and maintaining disclosure
            controls and procedures (as defined in Exchange Act Rules 13a-15(f)
            and 15d-15(f)) for Global Resource Corporation and I have done the
            following:

            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 Global Resource Corporation, 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.    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 Global Resource Corporation's
                  disclosure controls and procedures and presented in this
                  annual 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 annual report any change in Global Resource
                  Corporation's internal control over financial reporting that
                  occurred during Global Resource Corporation's fourth fiscal
                  quarter that has materially affected, or is reasonably likely
                  to materially affect, Global Resource Corporation's internal
                  control over financial reporting; and

      5.    I have disclosed, based on my most recent evaluation of internal
            control over financial reporting, to Global Resource Corporation's
            auditors and the audit committee of the Global Resource
            Corporation's board of directors:

            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
                  Global Resource Corporation'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 Global
                  Resource Corporation's internal control over financial
                  reporting.
