Loop over multiple arrays

Hi All
I need really really help with this :-

I have two files ( File1 , File 2) both files are output of two different scripts.

File1 usually has a list of names ( sometimes 3 names sometimes 5 sometimes more , depends about the output of the script)
File2 usually has a list of numbers (ages) (depends about how many names in File1)

So if File1 has 3 names , File2 will have 3 different ages.

For example ,

If file1 has

Code:
Jon
Kim
Lee


File2 will has

Code:
23
44
21

I am trying to have my output to be like this :-

Code:
Jon is 23 
Kim is 44
Lee is 21

my current out put is :-

Code:
Jon is 23
Jon is 44
Jon is 21
Kim is 23
Kim is 44
Kim is 21
Lee is 23
Lee is 44
Lee is 21

here is my script :-

Code:
for NM in `cat /tmp/File1 | cut -d'=' -f2 | sort -u`; do 
  for AG in `cat /tmp/File2 | cut -d'=' -f2 | sort -u`; do 
 
    echo -ne  "$NM is $AG)"  >> /tmp/Output 
 
  done 
done


Can someone please help!
