UNIX for Dummies Questions & Answers

Hello all,
I have two files:
file1:
data1 data2 data3
data4 data5 data6
data7 data8 data9

file2:
reference

I need to paste both files with the following output:
data1 data2 data3 reference
data4 data5 data6 reference
data7 data8 data9 reference

I tried using the paste command, but the reference only apply to the first row.

Any suggestion?
thank you in advance.

Code:

mLine2=`cat file2`
while read mLine1
do
 echo ${mLine1}" "${mLine2}
done < file1

Hello shell_life,
A question, mLine1 = 'cat file1'

Thank you.

It is back tick, not single quote.
