Dear Fellow Shareholder:

We are sending you this reminder letter because we have not yet received your vote. As you know, the Special Meeting of Shareholders of PHC, Inc. is scheduled to be held on October 26, 2011, at 9:00 a.m., at the corporate offices of PHC, Inc. The merger requires 2/3 of the outstanding shares to vote in favor for approval. IT IS VERY IMPORTANT THAT YOU VOTE YOUR SHARES ON THE MERGER. IF YOU DO NOT VOTE YOUR SHARES, IT HAS THE SAME EFFECT AS A VOTE AGAINST THE MERGER.

Enclosed you will find another proxy card, which includes a control number that you will need to cast your vote. We kindly ask that you please take a moment to vote your shares via phone or internet if you are not planning to attend the meeting in person. If you have any question or need additional information, please contact our proxy solicitor, Georgeson Inc., toll-free at [phone]. They will be happy to assist.

Thank you for your time and consideration. We look forward to hearing from you soon.

Best Regards,

/s/ Bruce Shear
