Replace & sign to &amp word

Hi, I have text file abc.txt. In this file, I have the following data.

Input:
Code:
Mr Smith &amp Mrs Smith
Mr Smith &apos Mrs Smith
Mr Smith & Mrs Smith
Mr Smith& Mrs Smith
Mr Smith &Mrs Smith

Output:
Code:
Mr Smith &amp Mrs Smith
Mr Smith &apos Mrs Smith
Mr Smith &amp Mrs Smith
Mr Smith&amp Mrs Smith
Mr Smith &ampMrs Smith

In line 3, 4, and 5. I want to change & sign to &amp word but do not want to change anything in line 1, and line 2. If I use

Code:
sed 's/&/&amp/g' abc.txt

command, it changes to &amp everywhere.

Thanks for your help

Naveed
