                      RULE 13a-14/15d - 14(a) CERTIFICATION

I, Christopher L. Coccio, Chief Executive Officer and President (principal
executive and accounting officer), certify that:

1.    I have reviewed this quarterly report on Form 10-QSB of Sono-Tek
      Corporation;

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 circumstance under which such
      statements were made, not misleading with respect to the period covered by
      this quarterly report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this quarterly report, fairly present in all
      material respects the financial condition, results of operations and cash
      flows of the small business issuer as of, and for the periods presented in
      this quarterly report;

4.    I am 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) and 15d-15(f) for the small business issuer and I have:

            a) Designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under my
            supervision, to ensure that material information relating to the
            small business issuer, including its consolidated subsidiaries, is
            made known to me by others within those entities, particularly
            during the period in which this report is being prepared;

            b) Designed such internal control over financial reporting, or
            caused such internal control over financial reporting to be designed
            under my 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 small business issuer's
            disclosure controls and procedures and presented in this report my
            conclusions about the effectiveness of disclosure controls and
            procedures, as of the end of the period covered by this report based
            on such evaluation; and

            d) Disclosed in this report any change in the small business
            issuer's internal control over financial reporting that occurred
            during the small business issuer's most recent fiscal quarter that
            has materially affected, or is reasonably likely to materially
            affect, the small business issuer's internal control over financial
            reporting; and


                                       22


5.    I have disclosed, based on my most recent evaluation of internal control
      over financial reporting, to the small business issuer's auditors and the
      audit committee of the small business issuer'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 small business
            issuer'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 small business
            issuer's internal controls over financial reporting.
