PART I - REGISTRANT INFORMATION

- --------------------------------------------------------------------------------

      Full Name of Registrant

      Tridex Corporation

      Address of Principal Executive Office (Street and Number)

      61 Wilton Road

      Westport, CT 06880



PART II - RULES 12b-25(b) AND (c)

      If the subject report could not be filed without unreasonable effort or
      expense and the registrant seeks relief pursuant to Rule 12b-25(b) the
      following should be completed. (Check box if appropriate)

      |X|   (a) The reasons described in reasonable detail in Part III of this
            form could not be eliminated without unreasonable effort or expense;

      |X|   (b) The subject annual report, semi-annual report, transition report
            on Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof will
            be filed on or before the fifteenth calendar day following the
            prescribed due date; or the subject quarterly report or transition
            report on Form 10-Q, or portion thereof will be filed on or before
            the fifth calendar day following the prescribed due date; and

      |_|   (c) The accountant's statement or other exhibit required by
            Rule12b-25(c) has been attached if applicable.

- --------------------------------------------------------------------------------

PART III - NARRATIVE

State below in reasonable detail the reasons why the Form 10-K, 11-K, 10-Q,
N-SAR, or the transition report or portion thereof, could not be filed within
the prescribed time period.

During the first calendar quarter of the current year, the Registrant's Chief
Financial Officer, who was responsible for generating the Registrant's
accounting and financial reports and overseeing the public reporting process,
resigned. The Registrant hired a new Chief Financial Officer as of June 1, 2000.
The hiring of the new Chief Financial Officer late in the fiscal quarter has
hampered the Registrant's ability to finalize its interim financial statements
and Form 10-Q for the period ended June 30, 2000.

For the reasons set forth above, the Registrant's inability to timely file its
Quarterly Report on Form 10-Q for the period ended June 30, 2000 cannot be
eliminated without unreasonable effort or expense. The Registrant intends to
file its Quarterly Report no later than the fifth day after the due date of the
Quarterly Report.

PART IV - OTHER INFORMATION

- --------------------------------------------------------------------------------

      (1) Name and telephone number of persons to contact in regard to this
notification:

      Seth M. Lukash, Chairman and CEO (203) 226-1144

      (2) Have all other periodic reports required under section 13 or 15(d) of
the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940 during the preceding 12 months or for


                                       2


such shorter period that the registrant was required to file such report(s) been
filed? If the answer is no, identify report(s).

                                                                  |X| Yes |_| No

      (3) Is it anticipated that any significant change in results of operations
from the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

                                                                  |X| Yes |_| No

      If so: attach an explanation of the anticipated change, both narratively
and quantitatively, and if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

Operating losses reported in the first quarter 2000 continued in the second
quarter. The Company anticipates reporting a pre-tax loss from operations of
$2,267,000 in the second quarter of this year, and $6,008,000 for the six-month
period ended June 30, 2000, compared to a pre-tax loss from operations of
$982,000 in the first quarter 1999 and $2,031,000 during the first six months of
1999. The loss during the first quarter of this year, however, is offset by gain
on the sale of discontinued operations of approximately $5,588,000.

The Registrant has caused this notification to be signed on its behalf by the
undersigned thereunto duly authorized.
