ITEM 2.          ACQUISITION
- ------

     On June 3, 1999, pursuant to a securities purchase agreement dated April
28, 1999, as amended, between the Registrant, Sterling Diagnostic Imaging, Inc.,
a Delaware corporation ("SDI") and SDI Investments, L.L.C., a Delaware limited
liability company ("SDI Investments") (the "Securities Purchase Agreement"), the
Registrant purchased 100% of the issued and outstanding shares of capital stock
of DRC Holding Corp., the parent company of Direct Radiography Corp., a Delaware
corporation ("DRC"), a manufacturer of digital X-ray systems for medical imaging
and non-destructive testing applications.  On June 3, 1999, pursuant to a
Contract of Sale between Glasgow Land Company ("Contract of Sale"), the
Registrant also purchased from Glasgow Land Company, L.L.C., a Delaware limited
liability company and a wholly-owned subsidiary of  SDI Investments, the land
and buildings in Glasgow, Delaware at which DRC conducts its business.   The
Registrant intends to continue to conduct the business operations of DRC as
conducted prior to the acquisition. The aggregate purchase price for the stock
of DRC Holding and for the real estate and buildings was approximately
$20,000,000, of which approximately $7,000,000 was paid in cash and of which
approximately $13,000,000 was paid by delivery of 1,857,142 shares of the
Registrant's Common Stock, par value $.01 per share (the "Purchase Price"). The
cash portion of the Purchase Price was paid out of working capital. Immediately
following the acquisition, SDI Investments transferred 473,571 shares to E. I.
Du Pont de Nemours and Company ("Dupont") and assigned to Dupont certain of its
rights under the Securities Purchase Agreement.

     Pursuant to the Securities Purchase Agreement, the Registrant granted
certain registration rights to SDI, Glasgow and Dupont.  The Registrant is
obligated to file a Registration Statement under the Securities Act of 1933 on
Form S-3 (or any successor short form registration involving a similar amount of
disclosure) to register for resale shares of Common Stock issued by the
Registrant in connection with the acquisitions.

     The terms of the stock purchase are more fully described in the Securities
Purchase Agreement and the terms of the real estate purchase are more fully
described in the Contract of Sale.  The terms of this transaction and the
consideration received by SDI and its affiliated entities were as a result of
arm's length negotiations between representatives of SDI, SDI Investments,
Glasgow and the Registrant.
