    As previously reported, sales and operating income declined in the
first six months of fiscal year 2005, because of delays in deliveries
under existing contracts, and the award of new contracts, and as a
result of planned increased marketing and development costs for ITI.
In September, the Company received a $1,600,000 contract to supply
T-36M ramp test sets to the Army National Guard. Delivery of all units
under this contract is expected to be completed during the current
fiscal year

    Investment in new product development continues for both avionics
and ITI's marine systems in order to meet the expected customer needs
and to remain as leaders in the respective industries. For the
avionics division, TEL continues its work on the next generation of
IFF (Identification, Friend or Foe) test sets in anticipation of U.S.
and NATO requirements for more sophisticated IFF testing. The Company
anticipates that most of the AN/APM-480's, previously sold, will be
returned and modified, in the future, to accommodate more
sophisticated IFF testing. Although there is no assurance that the
Company will receive any such modification contracts, TEL believes
that it is well positioned to obtain such contracts. For marine
systems, engineering expenditures include improvements to its tide
gauge, and upgrading its sounders with a new Windows operating system
which will allow for further improvements to these instruments. The
Company has been active in responding to requests for quotation for
new government programs, which will award new test equipment
contracts, and is currently in the process of submitting proposals for
large government programs. Active pursuit of opportunities in both the
commercial and government avionics and marine systems markets, both
domestically and internationally, continues, along with its efforts
with Semaphore Capital Advisors LLC to pursue growth through
acquisitions and alliances of compatible businesses or technologies.

    The Annual Meeting of Shareholders will be held on December 8,
2004. The meeting will be at the Company's facilities at, 728 Garden
Street, Carlstadt, NJ, at 4:00 p.m.
