Exhibit 99.1

Letter to Prospective Clients Engaged in a Procurement Process under which a PHS Proposal has
been Submitted but an Award has not Been Made

Dear [NAME]:

We recently announced an agreement to merge the parent companies of PHS Correctional Healthcare (PHS) and Correctional Medical Services (CMS). Combining two of the country’s leading correctional healthcare providers will create a single team with best-in-class experience, staffing depth, proven best practices and leadership on an unmatched, solid financial platform. We will also have the resources needed to invest in systems and innovations required to meet the evolving needs of clients such as [NAME OF PROSPECTIVE CLIENT].

Because you are currently considering a proposal from PHS, I want to make sure you are aware of this news and provide you with information about the intended transaction which we expect to finalize in the second quarter of 2011. Most importantly for the current procurement process, our merger is not yet final. That means:

	1)		Both companies remain completely separate organizations, competing in the open market and with rigid firewalls in place, which ensures there is no communication, collaboration or sharing of any proposal, cost proposals, market intelligence or any kind of proprietary information between the two organizations.
	2)		The PHS proposal submitted to work on behalf of [NAME OF PROSPECTIVE CLIENT] in response to your RFP stands completely as is; if our proposal is selected, we will honor and abide by all terms of our proposal.
	3)		The staff with whom you have been working at PHS will remain the same as you move forward through the procurement process.

Again, we believe this merger will bring together the best of both companies in ways that will directly benefit prospective clients like [NAME OF PROSPECTIVE CLIENT]. However, the merger is conditioned on appropriate regulatory and other approvals as a standard step in the process for any transaction such as this. Therefore, until the transaction is finalized it is business as usual and PHS stands fully behind all aspects of our proposal to you. If you have any questions, please contact me at your convenience.

Thank you.

Sincerely,
