Textarea content gets filtered

I am using options-framework. And, when I add any data to it something like this:
———————-
Address Line 1
Address Line 2

Tel: 1111111111
Mob: 0000000000
———————-
then it is giving output:
———————-
Address Line 1 Address Line 2 Tel: 1111111111 Mob: 0000000000
———————-

And, even when i am using html tags textarea, the html tags are get filtered.
