AN OPEN LETTER TO JOHN PALMER AND RICHARD LASHLEY
OF PL CAPITAL GROUP

April 9, 2010

Mr. John Palmer, Principal	Mr. Richard Lashley, Principal

Naperville, Illinois 60540	Chatham, New Jersey 07928

Dear Mr. Palmer and Mr. Lashley:

We read with interest the material you made public recently that detailed your so-called “plan” for corporate governance and financial performance at CFS Bancorp, Inc. We will reserve comment on this material for the appropriate venue, but we generally found it to be overly simplistic in its approach and misleading and inflammatory in its content.

There was one comment that we cannot in good conscious let go unaddressed in public. You noted that your plan would “Instill a sense of urgency and work ethic. Banking is not about magic formulas, its [sic] blocking and tackling by the right management team and staff.”

It’s one thing for you to say that you don’t like the way our team blocks and tackles. It’s another thing completely toattack our teamof highly capable, dedicated, experienced business and retail bankers who work for CFS Bancorp or Citizens Financial Bank by implying that they lack “a sense of urgency and work ethic.”

That is categorically false. Each of our 342 team members has worked tirelessly, with great urgency, to improve the institution’s performance and execute our Strategic Growth Plan in the face of the most challenging economic and banking environment our country has faced since the Great Depression. We are not only proud of our team, but also impressed by the efforts that they have put forth and humbled by the dedication they have shown in dealing with this challenging environment, all while maintaining our position as a strong, stable institution. There isno lack of effort or urgency at CFS Bancorp.

You have insulted this fine group of people without reason, impugning their character, falsely condemning them in the eyes of their fellow shareholders. Over the past 15 months, we have remained focused on running our business and executing our Strategic Growth Plan as you have repeatedly attacked our Chairman, his family, our senior management team and our Board. We understand that enduring such attacks is part of life as named executives and/or board members of a publicly held company.In attacking our dedicated employees, you have overstepped your bounds.

This might just be another proxy fight over another investment to PL, but to our shareholders, the Board, management, our employees, our clients and the communities we serve, CFS Bancorp is a lot more than a mere investment.We are proud to work with and on behalf of this great teamin meeting the financial service needs of both individuals and businesses in the communities we serve. Citizens Financial Bank has had a great history of service and success since 1934.

Best regards,

/s/ Thomas F. Prisby	/s/ Gregory W. Blaine
