                                 CERTIFICATIONS


      I, Carl H. Guild, Jr., certify that:


      (1)  I have reviewed this quarterly report on Form 10-QSB of
           Technical Communications 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 small business issuer as of, and for, the periods
           presented in this report;


      (4)  The small business issuer'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 small business issuer 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 small business issuer, 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 small business issuer'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 small business
                 issuer's internal control over financial reporting that
                 occurred during the small business issuer's most recent fiscal
                 quarter (the small business issuer's fourth fiscal quarter in
                 the case of an annual report) that has materially affected, or
                 is reasonably likely to materially affect, the small business
                 issuer's internal control over financial reporting; and


      (5)  The small business issuer's other certifying officer and I have
           disclosed, based on our 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
           (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
                 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 control over financial reporting.
