Bash regex help

I've been using the following regex below in a bash script on RHEL 5.5 using version
GNU bash, version 3.2.25(1)-release

I've tried using the script on RHEL 6.3 which uses GNU bash, version 4.1.2(1)-release

I assume there's been alot of changes to bash since that's quite a jump in revisions. I'm wondering if anyone can help me sort what might have to be modified in the code to make this work again.

If I enter an e-mail address in a simple format like:

user.user@test.com the scripts sees this as an invalid e-mail now, whereas before this would pass the regex.


Code:
#!/bin/bash
echo Enter the users e-mail address.

read ADDRESS

if [[ "$ADDRESS" =~ "^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$" ]] ; then
   echo $?
   echo Proceeding!!
else
   echo $?
   echo You entered an invalid e-mail address!!!
exit 1
fi

NAME
bashbug - report a bug in bash SYNOPSIS
bashbug [--version] [--help] [email-address] DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be mailed, it is saved in the file dead.bashbug in the invoking user's home directory. The bug report format outline consists of several sections. The first section provides information about the machine, operating system, the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec- tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged. ENVIRONMENT
bashbug will utilize the following environment variables if they exist: EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs. HOME Directory in which the failed bug report is saved if the mail fails. TMPDIR Directory in which to create temporary files and directories. SEE ALSO
