Hi Nasser,
I found by trial and error that you can use the following:
ScientificForm[Column[{n, m}], {5, 4},
NumberPadding -> {"", "0"},
NumberFormat -> (Row[{#1, "E", #3}] &)]
This seems to be a lack in Documentation, because
ScientificForm[expr,{n,f}] is not told about in the help. But it seems
to go like NumberForm.
