 I,
          Jerome
          I. Feldman, certify that:
 
 1.
              I
                  have reviewed this amended quarterly report on Form 10-Q/A of National
                  Patent Development Corporation; 
 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(s) 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 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 (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(s) 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 (or persons performing the equivalent functions): 
 (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.
