to $38  million  for the  quarter  ended March 31, 1998 from $36 million for the
first  quarter 1997 despite a reduction in first quarter 1998  operating  income
due to access charge/price cap and universal service fund reforms." Mr. DeSantis

first quarter 1997, reflecting the impact of certain rate reductions."

quarter 1998 was attributable to local dial tone services and enhanced  services

equipment at quarter end totaled $457 million as compared to $256 million a year
earlier."
