Item 5.   OTHER EVENTS
    
     Reference is made to Note J - "Commitments and
Contingencies" in Registrant's Notes to Consolidated Financial
Statements for the year ended December 31, 1996 set forth in
Registrant's 1996 Annual Report to Stockholders, regarding an
appeal by one of Registrant's insurance carriers from a
declaratory judgment obtained by Registrant requiring that the
insurance carrier pay clean-up costs in excess of the sum of
$6.7 million that Registrant had received in settlement with its
other three insurance carriers. Amounts paid by Registrant in
excess of the $6.7 million recovered, $1.5 million, plus the
discounted future costs of monitoring the site, $1.1 million,
totaled $2.6 million.

     On April 21, 1997, the California Court of Appeal issued its
decision in the case: Aydin Corporation, Respondent vs. First
State Insurance Company, Appellant, No. A068910 (97 Daily Journal
D.A.R. 5087), reversing the decision of the trial court that had
entered a judgment of Declaratory Relief in favor of the
Registrant regarding insurance coverage for the clean-up costs at
a site formerly leased by Registrant. The Court of Appeal ruled
that an "exception" to an exclusion in an insurance policy must
be treated as part of the policy's coverage provision, and that
the burden of proving the applicability of the exception be borne
by the insured. It was therefore prejudicial error for the trial
court to instruct the jury that it was the burden of the
insurance company to prove the nonexistence of the policy
coverage.

     The Registrant is reviewing the decision to determine
whether a further appeal to the California Supreme Court will be
made or allow the case to be returned to the trial court for a
new trial.

     As a result of this decision, the Registrant has recorded a
non-cash charge of $2.6 million for the First Quarter 1997.
