DURING THE REPORTING PERIOD.

          (i)  Light. At December 31, 1996, the capitalization of Light was
               approximately $2.9 billion (calculated on the basis of an
               exchange ratio on December 31, 1996 of 1.0391 Brazilian reais to
               one U.S. dollar) based on the book value of its assets in
               accordance with generally accepted accounting principles in the
               U.S.

               During the twelve-month period ended December 31, 1996, Light had
               earnings of approximately $224 million (calculated on the basis
               of an exchange ratio of 1.0219 Brazilian reais to one U.S.
               dollar, the average exchange ratio during the year ended 
               December 31, 1996).

         (ii)  EDELAP and Central Dique. At December 31, 1996, the combined
               capitalization of EDELAP and Central Dique was approximately $218
               million (calculated on the basis of an exchange ratio of one
               Argentine peso to one U.S. dollar) based on the combined book
               value of their assets in accordance with generally accepted
               accounting principles in the U.S.

               and Central Dique had combined earnings of approximately $1
               million (calculated on the basis of an exchange ratio of one
               Argentine peso to one U.S. dollar).

               million (calculated on the basis of an exchange ratio of one
               Argentine peso to one U.S. dollar). During the twelve-month
               period ended December 31, 1996, neither HIE Argener nor HIE Opco
               had any earnings because the project was still under
