Item 2.     Acquisition or Disposition of Assets.
            ------------------------------------

            On March 24, 1998, pursuant to an Agreement and Plan of Merger dated
as of  October  31,  1997 (the  "Merger  Agreement")  among  Allegheny  Teledyne
Incorporated (the "Company"),  Sea Merger Inc. ("Sub") and Oregon  Metallurgical
Corporation  ("Oremet"),  Sub was merged with and into Oremet,  whereupon Oremet
became a wholly owned subsidiary of the Company (the "Merger").

            The Company is a group of technology-based  manufacturing  companies
with significant concentration in special metals,  complemented by aerospace and
electronics,  industrial and consumer products. Oremet is an integrated producer
and distributor of titanium sponge, ingot, mill products and castings for use in
the aerospace, industrial, golf and military markets.

            Pursuant  to the  Merger  Agreement,  at the  effective  time of the
Merger each  outstanding  share of Common Stock,  par value $1.00 per share,  of
Oremet (other than shares owned by the Company or any subsidiary of the Company,
or shares held in Oremet's  treasury  immediately prior to the effective time of
the  Merger)  was  converted  into the right to receive  1.296  shares of Common
Stock,,  par value $.10 per  share,  of the  Company  (with cash paid in lieu of
fractional shares).  The foregoing  conversion ratio was determined on the basis
of arms' length negotiations between representatives of the Company and Oremet.
