Calamos Asset Management, Inc. Announces Assets Under Management as of June 30, 2007

Also Announces Termination of Additional Compensation Agreements on Two Closed-End Funds

     NAPERVILLE, Ill., July 11, 2007 — Calamos Asset Management, Inc. (NASDAQ: CLMS) today reported assets under management of $43.8 billion as of June 30, 2007, compared with $43.7 billion one month ago and $45.8 billion one year ago.

At Month End (in billions)	June 2007			May 2007			June 2006
Mutual funds		$	33.3		$	33.0		$	34.2
Separately managed accounts		$	10.5		$	10.7		$	11.6
Total assets under management		$	43.8		$	43.7		$	45.8

     Assets under management as of June 30, 2007 included $840.0 million raised in the initial public offering of the firm’s fifth closed-end fund, the Calamos Global Dynamic Income Fund (NYSE: CHW). If the underwriters’ over-allotment option is exercised, an additional $115.0 million in total common share assets could be raised. Related to this offering, Calamos incurred a $6.9 million one-time aggregate structuring fee, which is expected to reduce second quarter 2007 income by approximately 4 cents per diluted share.

Remaining Closed-End Fund Agreements Terminated

     In other developments, Calamos has agreed to terminate the remaining additional compensation agreements on two of its closed-end funds. The agreements required Calamos to make recurring payments over time based on the assets of the Calamos Convertible Opportunities and Income Fund (NYSE: CHI) and the Calamos Strategic Total Return Fund (NYSE: CSQ). In exchange for termination of these agreements, Calamos will make a lump-sum payment of approximately $19.5 million, or approximately 11.5 cents per diluted share. The expense will be recorded in the second quarter of 2007 as a marketing and sales promotion expense. Termination of these agreements is expected to have a positive impact on Calamos’ operating income by eliminating the approximately $2.6 million that it would have otherwise paid annually under the agreements, and to have a positive annualized after-tax impact of approximately 1.5 cents per diluted share.
