DESCRIPTION OF AMENDED LLC AGREEMENT

Item 1.01. Entry into a Material Definitive Agreement.

     On November 2, 2004, Calamos Asset Management, Inc. (the “Company”), upon consummation of its initial public offering of 20,000,000 shares of its Class A common stock, applied a portion of the net proceeds from the initial public offering to purchase 3,000,000 newly issued membership units from Calamos Holdings LLC and the remaining net proceeds to purchase from Calamos Family Partners, Inc. an additional 17,000,000 membership units in Calamos Holdings LLC. In connection with its acquisition of these membership units, the Company executed the Second Amended and Restated Limited Liability Company Agreement of Calamos Holdings LLC, effective as of November 2, 2003, by and among Calamos Family Partners, Inc., John P. Calamos and the Company (the “Amended LLC Agreement”) and became the sole Manager of Calamos Holdings LLC.

     The Amended LLC Agreement was executed on terms and conditions substantially as described in the Company’s Registration Statement on Form S-1 (Registration No. 333-117847) (the “Registration Statement”). The description of the Amended LLC Agreement, which appears in the Registration Statement under the heading “Management — Governance Documents — Limited Liability Company Agreement of Calamos Holdings LLC,” is incorporated herein by reference and a copy of such description is included herewith as Exhibit 99.1.

     Calamos Family Partners, Inc. owns all outstanding shares of the Company’s Class B common stock. John P. Calamos, through his control of Calamos Family Partners, Inc., beneficially owns all outstanding shares of the Company’s Class B common stock and, therefore, has approximately 97.1% of the combined voting power of all outstanding shares of the Company’s common stock.
