How to find a certain string in a file and replace it with a value from another file using sed/awk?

I do not want to replace with fixed values. I have to search for the string OUT in the new file(data.txt) and replace the OUT in file1 with the corresponding value(it may be 0/1/2/3 , anything)
that is have to grep for OUT in the file and find the value that is beside it!!
