COMPANY AMENDS ITS $275 MILLION UNSECURED CREDIT FACILITY

Cleveland, Ohio (September 15, 2010)-CBIZ, Inc. (NYSE:CBZ)(“Company”) today announced that it has entered into an agreement with Westbury (Bermuda) Ltd. (“Westbury”), a company organized by CBIZ founder Michael G. DeGroote, to purchase approximately 7.7 million shares of the Company’s common stock at a price of $6.25 per share. The Company also agreed to purchase an option expiring on September 30, 2013 to purchase up to approximately 7.7 million shares of the Company held by Westbury at a price of $7.25 per share.

Westbury, the Company’s largest shareholder prior to the consummation of the transaction, has agreed to the sale and option arrangements with respect to its entire ownership interest in the Company as part of a program to facilitate Mr. DeGroote’s estate planning. Prior to the sale, Westbury’s holdings of approximately 15.4 million shares of the Company represented approximately 25% of the total shares outstanding of CBIZ.

Concurrently, the Company today also announced that it has amended its $275 million unsecured credit facility led by Bank of America, NA. The amendment provides the Company with the flexibility to purchase Westbury’s shares, to address a variety of options to refinance its Convertible Notes due in June of 2011, and to continue its strategic growth strategy which includes future acquisitions.

“We are pleased with our unique national position in the professional services marketplace and the underlying health of our business which enabled us to accommodate this transaction with Mr. DeGroote,” stated Steven Gerard, CBIZ Chairman and CEO. “We will continue to be opportunistic with our use of capital to create long-term value for the CBIZ shareholder. Our cash flow continues to be strong and we remain focused on our growth goals by focusing on strategic acquisitions that will complement the organic growth of our business. To reiterate our earlier guidance for 2010, we continue to expect to achieve earnings per share for the full year within a close range of the $0.52 per share reported for 2009 and full year EBITDA this year within a close range of the $85 million achieved in 2009,” concluded Gerard.
