                    CERTIFICATION OF CHIEF EXECUTIVE OFFICER
      AS ADOPTED PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002
                            RULE 13a-14(a)/15d-14(a)

I, Glenn H. Epstein, certify that:

    1.            I have reviewed this quarterly report on Form 10-Q of
                  Intermagnetics General Corp. ("the Registrant");

    2.            Based on my knowledge, this quarterly 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 quarterly 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)) and internal control over financial
                  reporting (as defined in Exchange Act Rules 13a-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 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 the Registrant'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 annual report based on such evaluation; and

                      d.  disclosed in this annual 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 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:

                      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.
