FOR VALUE RECEIVED, IT IS AGREED AS FOLLOWS:

         1 . The promissory notes and other indebtedness secured by the Mortgage
has been modified by that certain Third Modification Agreement of even date
herewith between Bowmar Instrument Corporation, an Indiana corporation
("Borrower") and Bank and consented to by Mortgagor (the "Third Modification
Agreement"). In addition, pursuant to the Third Modification
   2
Agreement, Bank has agreed to provide Borrower with an additional revolving line
of credit/term loan in the principal amount of $1,200,000.00 (the "RLT")
secured by, among other things, the Mortgage.  In connection with the
modification of such indebtedness and the extension of such additional credit,
the Mortgage is hereby modified as provided in this Modification.

         2. The Mortgage is hereby amended to secure, in addition to the
indebtedness and obligations of Borrower and Mortgagor described therein, the
obligation of Borrower to repay all advances made by the Bank to the Borrower
under the RLT. Hereinafter, the term "Obligations," as defined in the Mortgage,
shall include, in addition to the other indebtedness described in the Mortgage,
the RLT. The final maturity date of the RLT is March 31, 2002.

         3. This Modification shall not affect or impair the lien or priority of
the Mortgage, as amended, with respect to the property subjected to the
Mortgage.

         4. All terms and provisions of the Mortgage shall remain in full force
and effect except as specifically modified herein and in the Third Modification
Agreement.

         5. This Modification may be executed in counterparts, all of which
executed counterparts shall together constitute a single document. Signature
pages may be detached from the counterparts and attached to a single copy of
this Modification to physically form one document.

         IN WITNESS WHEREOF, these presents have been executed as of the date
first written above.
