Item 2.  Acquisition or Disposition of Assets

         On July 5, 1995 (the "Closing Date"), Diagnostic/Retrieval Systems,
         Inc. (the "Company"), through a wholly-owned subsidiary of Photronics
         Corp., a New York corporation and a wholly-owned subsidiary of the
         Company ("Photronics"), acquired substantially all of the assets of
         Opto Mechanik, Inc. ("OMI"), a Delaware corporation, pursuant to an
         Agreement for Acquisition of Assets dated May 24, 1995, as amended July
         5, 1995, between Photronics and OMI (the "Agreement"), and approved by
         the United States Bankruptcy Court for the Middle District of Florida
         on June 23, 1995. Pursuant to the Agreement, the Company paid a total
         of $5,450,000 consisting of i) $1,150,000 in cash to PNC Bank,
         Kentucky, Inc. ("PNC"), ii) a note to PNC in the principal amount of
         $1,450,000 to be paid in 48 equal monthly installments of principal and
         interest commencing with the first day of the month following the
         Closing Date (the "PNC Note"), iii) $2,550,000 in cash to MetLife
         Capital Corporation and iv) a note in the principal amount of $300,000
         to OMI payable in 6 equal monthly installments of principal and
         interest commencing on August 5, 1995 (the "OMI Note"). The PNC Note
         bears interest at a floating rate equal to the lesser of i) PNC's
         stated prime interest rate plus 0.5%, or ii) the prime rate as reported
         by the Wall Street Journal plus 0.5%. The OMI Note bears interest at a
         rate of 9.5% per annum. The cash consideration paid in the acquisition
         was obtained from the Company's working capital.

         OMI, located in Melbourne, Florida, designs and manufactures
         electro-optical sighting and targeting systems used primarily in
         military fire control devices and in various weapons systems.

         For accounting purposes, the acquisition of OMI will be accounted for
         as a purchase. Reference is made to Item 7 for additional information.
