CBIZ TO OFFER $85 MILLION CONVERTIBLE SENIOR SUBORDINATED NOTES

NET SHARE SETTLEMENT FEATURE PROVIDES FOR PRINCIPAL TO BE REPAID IN CASH

Cleveland, Ohio (May 22, 2006)—CBIZ, Inc. (NASDAQ: CBIZ) today announced its intention to offer $85 million in aggregate principal amount of Convertible Senior Subordinated Notes due 2026. The Notes are being offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. The company also intends to grant the initial purchaser an option to purchase up to an additional $15 million in aggregate principal amount of the Notes.

The company intends to use approximately 50% of the proceeds from the sale of the Notes to repurchase shares of its common stock that may become available from certain institutional buyers of the Notes in connection with their hedging strategies concurrent with the issuance of the Notes. The remaining balance of the proceeds will be used to repay a portion of the $48 million outstanding balance under the company’s $100 million unsecured credit facility or for other general corporate purposes.

The Notes may be converted, under certain circumstances, into cash and, at the company’s election, shares of the company’s common stock at a conversion rate to be determined, subject to adjustment upon certain events. The Notes contain a net settlement feature so that upon conversion, the company will deliver cash equal to the lesser of the aggregate principal amount of Notes to be converted and the company’s total conversion obligation, plus cash or shares of the company’s common stock at the company’s election, for the remainder, if any, of the conversion obligation.

The Notes will rank junior in right of payment with all of the company’s existing and future senior indebtedness. The Notes will bear interest at a fixed rate, payable semiannually, and beginning on June 6, 2011 the company may be required to pay contingent interest under certain circumstances.
